At present, the structure of the rubber slicer on the market is a guillotine type structure, which is completely different from our company’s drum type structure. The following is an introduction to their respective working principles, structural characteristics and how to select them.
1 The common guillotine structure on the market
The schematic diagram of its structure is shown in Figure 1. Place the rubber block (2) flat on the workbench (1), and the guillotine knife (3) will reciprocate up and down under the action of the drive system (4) to cut the rubber block. The drive system can be electromechanical drive or hydraulic system drive.
Figure 1: The working principle of the guillotine glue cutting machine
The drive system of the guillotine type glue cutting machine generally adopts a combination of electric power system and hydraulic system, while the drum type glue cutting machine generally adopts the direct drive of the motor-reducer transmission device. The appearance comparison is as follows.
Guillotine Glue Cutter VS Roller Glue Cutter
2 Performance comparison of guillotine type and drum type glue cutting machine
2.1 Capacity comparison experiment
2.1.1 Test equipment: For the convenience of comparison, two glue cutting machines with the same shear force were used for comparison. That is, a 100KN guillotine type glue cutting machine and a 100KN drum type glue cutting machine each;
2.1.2 Test raw materials: SBR block (SBR1712), each with a net weight of 35 kg; its cross-sectional size: 500×110, and a length of about 650; the number of test raw materials: 10 packs;
2.1.3 Test purpose: Cut 10 packs of test raw materials into rubber sheets with a thickness of about 20~40mm along the section. Compare the time and production efficiency required for shearing with these two equipments.
2.1.4 Test method:
1) Guillotine type glue cutting machine: place the test material flat on the roller on the surface of the workbench at a suitable position, start the hydraulic system, and the guillotine knife moves downward to cut the test material from the section, and then lift the guillotine knife to complete a cut ; Move the test material about 20~40mm to the position of the guillotine knife, start the motion of the guillotine knife, cut the test material from the cross section, and complete the secondary shearing; in turn, it is necessary to repeat the above operation for about 30 times to complete a package of test materials. Cut complete.
In order to make the test data more accurate and in line with reality, repeat the operation with 10 packs of test raw materials, and take the average value of the required time. See Table Performance comparison of guillotine type and drum type glue cutting machine
In order to make the test data more accurate and in line with reality, repeat the operation with 10 packs of test raw materials, and take the average value of the required time. See Table 1.1.
Table 1: The average time required for shearing work per package of test material is listed below:
| Step | Implementation content | Time required (seconds) |
| 1 | Put the test material flat on the roller on the surface of the worktable in a suitable position | 32 |
| 2 | Start the hydraulic system, and the guillotine moves downward to cut the test material from the section to complete the first shearing | 11.5 |
| 3 | Move the test material about 20~40mm to the position of the guillotine | 18.5 |
| 4 | Start the hydraulic system, and the guillotine moves downward to cut the test material from the section to complete the second shearing | 11.8 |
| 5 | Repeat steps 3 and 4 above to complete the next 30 cuts | 909 |
Based on the above data, the time required to complete the shearing work of each package of test raw materials is: 952.5 seconds.
2) Roller type rubber cutting machine: start the motor and start working, place the test material in the guide trough from top to bottom, and cut off the rubber blocks continuously under the action of the shearing pair formed by the hob and the roller. and fall into the receiving trough. The thickness of the sheared rubber block is automatically controlled by the machine. The time required to complete the shearing work of each package of test raw materials is shown in Table 2.
Repeat the above operation with 10 packs of test raw materials, and take the average value of the required time. List Table 2.
Table 2: The average time required for shearing work per package of test material is listed below:
| Step | Implementation content | Time required (seconds) |
| 1 | Manually place the test materials in the guide trough from top to bottom | 26 |
| 2 | Drum type glue cutting machine automatically completes the shearing of a package of test raw materials | 15 |
Based on the above data, the time required to complete the shearing work of a package of test raw materials is: 41 seconds.
3) Test results:
The time required for the guillotine cutter to complete the shearing work of each package of test raw materials is 952.5 seconds;
The time required for the drum-type glue cutter to complete the shearing work of each package of test raw materials is 41 seconds.
Compared with the two, the time required to complete the shearing work of each package of test raw materials differs by nearly 23 times;
Compared with the cutting effect, it is found that the drum type glue cutting machine cuts into a uniform thickness, and the guillotine type glue cutting machine has a large thickness deviation.
4) Reason analysis:
The guillotine type glue cutting machine adopts manual operation in the whole cutting process, while the drum type glue cutting machine adopts manual operation only when feeding each package, and other links are automatically controlled by the machine. Therefore, the slicing efficiency is high; since the thickness of the guillotine type glue cutting machine is completely controlled by manually pushing the glue block, the deviation is large; while the drum type glue cutting machine is completely controlled by the machine, which is related to the speed of the machine and the structure of the drum , the deviation is small.
