In this embodiment, the inner bottom surface of the box body 51 is square. The box body 51 is connected to the conveying device 11. The inner wall of the box body 51 is provided with an anti-sticking layer 52, such as a wax layer or a silicone oil coating.

[0029] The driving and conveying device 11 drives the box body 51 to the side of the injection device 2, and uses the injection device 2 to inject liquid hot-melt pressure-sensitive adhesive into the box body 51. Then, the driving and conveying device 11 drives the box body 51 to the side of the cooling and molding device 3, and uses the cooling and molding device 3 to cool the liquid hot-melt pressure-sensitive adhesive in the box body 51 into a solid state. Then, the driving and conveying device 11 drives the box body 51 to the slitting device 4, and the slitting device 4 cuts the solid hot-melt pressure-sensitive adhesive into adhesive blocks of a predetermined size.

[0033] Reference Figure 3 Since the viscosity of the liquid hot melt pressure-sensitive adhesive is related to the temperature, when the temperature is too low, the viscosity of the liquid hot melt pressure-sensitive adhesive will increase, which will affect the fluidity of the liquid hot melt pressure-sensitive adhesive; in order to make the viscosity of the liquid hot melt pressure-sensitive adhesive controllable, a heating pipe 221 is buried in the connection box 22, and the connection box 22 is also equipped with a control module 27 and a temperature sensor 28. The temperature sensor 28 is located in the connection box 22, and the control module 27 is connected to the heating pipe 221 and the temperature sensor 28. The control module 27 controls the heating pipe 221 to work in response to the detection signal of the temperature sensor 28; when the temperature sensor 28 detects that the temperature of the liquid hot melt pressure-sensitive adhesive is too low, the temperature sensor 28 sends a signal to the control module 27, and the control module 27 controls the heating pipe 221 to work to heat the liquid hot melt pressure-sensitive adhesive.

The blowing members 32 are preferably hair dryers. A cooling position 12 is formed above the conveying device 11, and a plurality of blowing members 32 are arranged facing the cooling position 12 and surrounding the cooling position 12.

[0036] The driving conveying device 11 drives the box body 51 to the cooling position 12, and drives the plurality of blowing members 32 to blow air to the liquid hot-melt pressure-sensitive adhesive in the box body 51 so as to turn it into a solid.

[0039] Reference Figure 5 and Figure 6 The locking assembly 44 includes a plurality of gas expansion members 441, such as rubber gas expansion strips. Each mounting slot 421 has a mounting slot 422 on its inner wall. One gas expansion member 441 is correspondingly arranged in one mounting slot 422. Each gas expansion member 441 is used to lock the pressing member 43 after expansion. The mounting block 42 has an air supply channel 423, which is connected to the inside of each gas expansion member 441. Figure 4 The mounting block 42 is provided with a ventilation hose 45 connected to the air supply passage 423 , and the ventilation hose 45 is connected to an air supply member 46 , which can maintain / stop supplying compressed gas to the air supply passage 423 .

One end of the return spring 47 is connected to the inner wall of the installation slot 421, and the other end of the return spring 47 is connected to the pressing member 43. Normally, the pressing member 43 does not participate in the pressing and cutting, and the return spring 47 is in a relaxed state. To allow the pressing member 43 to participate in the pressing and cutting, the pressing member 43 needs to be moved downward, and the return spring 47 will be compressed. In addition, in order to facilitate the pressing and cutting of the pressing member 43, the pressing and cutting member 43 includes a blade 432 at the bottom, so that the pressing and cutting member 43 can be pressed and cut easily. Figure 6For reference, the length of the blade 432 in the front-to-back direction is the same as the side length of the bottom surface of the box body 51.

[0042] To change the size of the cut rubber block, it is necessary to first release the lock of all the cutting pieces 43, then manually move the cutting pieces 43 that need to be involved in the cutting downward, and then reuse the air supply piece 46 to supply compressed gas to the air supply channel 423 so that the air expansion piece 441 locks the cutting piece 43.

[0043] If the rubber block is to be cut horizontally or vertically, it is only necessary to drive the rotary driving member 414 to drive the plurality of pressing and cutting members 43 to be distributed front and back, and then adjust the position of the pressing and cutting members 43 that need to participate in the pressing and cutting according to the needs.

At this time, the air expansion member 441 releases the lock on the pressing and cutting member 43. Then, the pressing and cutting member 43 that needs to participate in the pressing and cutting is manually moved down. Then, the air supply member 46 is used again to supply compressed air to the air supply passage 423 so that the air expansion member 441 locks the pressing and cutting member 43. The vertical driving member 412 and the horizontal driving member 413 are driven to drive the pressing and cutting member 43 to move and cut the solid hot-melt pressure-sensitive adhesive. Finally, when the box body 51 is transported by the transport device 11 to the point where the opening faces one side, the worker uses a tool to take out the rubber block in the box body 51 .
