The top inner wall of the collection cylinder 401 is slidably connected with the rod body 402, which keeps the rod body 402 moving vertically along the top inner wall of the collection cylinder 401. The top of the rod body 402 is fixedly connected with a driving rod 409, so that when the driving rod 409 is moved upward by the force of the pushing block 8, the driving rod 409 drives the rod body 402 to move vertically at the same time. The bottom of the driving rod 409 is supported by the spring A5 It is elastically connected to the top of the collecting cylinder 401, and the compression force of the spring A5 drives the driving rod 409 to move downward, so that the driving rod 409 drives the closing ball 403 at the bottom to fit and seal with the top of the discharge pipe 405. The bottom of the rod body 402 is fixedly connected with the closing ball 403, so that the closing ball 403 is driven to move vertically at the same time during the vertical movement of the rod body 402. The inner wall of the driving rod 409 is slidably connected with the wedge block 411, so that the wedge block 411 moves vertically along the inner wall of the driving rod 409. The bottom of the wedge block 411 is connected to the inner wall of the driving rod 409 by the spring B404. The inner wall of the driving rod 409 is elastically connected, and the force of the spring B404 drives the wedge block 411 to move upward, so that the wedge block 411 maintains the clamping and fixing effect with the card slot. The outer wall of the driving rod 409 is plugged with a rubber head 410, and the rubber head 410 is installed and removed by plugging. The outer wall of the rubber head 410 is provided with a card slot, and the inner wall of the card slot is clamped with the outer wall of the wedge block 411 to achieve the effect of fixing the rubber head 410, and the outer end bottom of the rubber head 410 is made of flexible rubber material to reduce the wear on the push block 8.

[0033] Reference Figure 1-Figure 3The bottom of the collecting cylinder 401 is fixedly connected with a discharge pipe 405, and the bottom of the discharge pipe 405 is fixedly connected with a metering cylinder 406, so that the liquid stored in the inner wall of the collecting cylinder 401 is transmitted to the inner wall of the metering cylinder 406 through the discharge pipe 405. The bottom of the metering cylinder 406 is fixedly connected with an extraction pump 407. By starting the extraction pump 407, the extraction pump 407 extracts liquid from the inner wall of the metering cylinder 406 for spraying. The bottom of the extraction pump 407 is fixedly connected with a transmission pipe 408, so that the extraction pump 407 transmits the glue to the nozzle 6 through the transmission pipe 408 for spraying. The transmission pipe 408 is fixedly connected to It is connected to a nozzle 6, and both ends of the nozzle 6 are fixedly connected to the front and rear sides of the inner wall of the shell 1, so that the shell 1 provides a supporting and fixing effect for the nozzle 6. Two groups of transmission rollers 3 are provided, one group of transmission rollers 3 is arranged at the upper end of the inner wall of the shell 1, and the outer wall of one group of transmission rollers 3 is fixedly connected to a pushing block 8, so that the pushing block 8 is driven to rotate and move at the same time during the rotation of the transmission rollers 3, and the outer wall of the pushing block 8 contacts the bottom of the outer wall of the rubber head 410. The other group of transmission rollers 3 is arranged at the lower end of the inner wall of the shell 1, and the top of the collecting cylinder 401 is fixedly connected to an injection pipe 7, through which glue can be continuously provided to the collecting cylinder 401.

[0034] Working principle: During the production and processing of the sealing easy-tear film, the staff winds the material for making the film on the outer wall of the winding roller 2, and then starts the winding roller 2 to rotate the winding roller 2 to pull and rewind the two groups of materials from right to left.

[0035] At the same time, the transmission roller 3 rotates and cooperates with the winding roller 2 to transport the material. During the rotation and transmission of the winding roller 2, the pushing block 8 set on the outer wall of the winding roller 2 rotates and moves at the same time, so that the outer wall of the pushing block 8 squeezes the bottom of the rubber head 410, causing the rubber head 410 to move upward, and the rubber head 410 drives the rod body 402 to move vertically. During the vertical movement of the rod body 402, the sealing ball 403 is separated from the top of the discharge pipe 405, thereby opening the discharge pipe 405, and allowing the glue stored in the inner wall of the collecting cylinder 401 to be discharged downward into the inner wall of the metering cylinder 406. At the same time, after the pushing block 8 moves away from the rubber head 410, the force of the spring B404 drives the driving rod 409 to reset downward, so that the rod body 402 drives the sealing ball 403 to close the top of the discharge pipe 405, thereby achieving the effect of automatically closing the discharge pipe 405 to discharge material.

[0036] And after long-term use, considering that the rubber head 410 is a flexible material and is prone to wear or damage, the wedge block 411 can be separated from the inner wall of the slot by pressing the wedge block 411, so as to release the fixed installation effect of the rubber head 410 and the driving rod 409, and the rubber head 410 can be disassembled outward, thereby achieving the purpose of replacing the rubber head 410 and preventing the rubber head 410 from being excessively worn after long-term use, thereby affecting the quantitative spraying effect.
