[0076] The driving mechanism includes:

[0077] The motor 22 is fixedly connected to one side of the chassis 1, and its output end is transmission-connected to the transmission assembly 23. The motor 22 provides torque, which is then transmitted to the groove wheel mechanism 24 through the transmission assembly 23, thereby causing the underground tunnel transmission shaft 5 to rotate periodically.

[0078] The grooved wheel mechanism 24 is rotatably connected to the chassis 1 and is transmission-connected to the transmission assembly 23;

[0079] A transmission shaft 5, which is rotatably connected to the chassis 1 and is transmission-connected to the grooved wheel mechanism 24;

[0080] The first gear 26 is rotatably connected to the transmission shaft 26, and one side of the first gear 26 is meshedly connected to a transmission wheel 28. The middle of the transmission wheel 28 is fixedly connected to an intermediate shaft 27 rotatably connected to the chassis 1. The outer wall of the intermediate shaft 27 is fixedly sleeved with a missing gear 25. One side of the missing gear 25 is meshedly connected to a driving tooth 21 connected to the feeder 9. During the rotation of the transmission 5, the first gear 26 is mobilized to rotate, which further drives the transmission wheel 28 to rotate. The missing gear 25 is driven by the intermediate shaft 27 to rotate, and then the driving tooth 21 is periodically driven to rotate periodically.

[0081] The sprocket wheel 6 is fixedly sleeved on the outer wall of the transmission shaft 5, and a chain is meshedly connected thereon. The clamp 3 is connected to two adjacent chains. The transmission shaft 5 rotates periodically, driving the sprocket wheel 6 to rotate, thereby driving the chain and the clamp 3 to move.

[0082] The blanking device 9 includes:

[0083] A drive pipe 70, which is rotatably connected to the chassis 1, fixedly sleeved with the drive gear 21, and has one end connected to a vacuum pump 29 through a rotary joint. The drive pipe rotates with the rotation of the drive gear 21, and the vacuum pump 29 performs the work of extracting internal gas.

[0084] A diversion pipe 73, which is fixedly connected to the drive pipe 70, and has the other end fixedly connected to a first spring 74. One end of the first spring 74 is fixedly connected to a sliding frame 76 that is slidably sleeved with the diversion pipe 73. Contact rollers 92 are rotatably connected to the periphery of the sliding frame 76. The sliding frame 76 can move on the diversion pipe 73, and the first spring 74 causes the sliding frame 76 to return to its position.

[0085] A diversion channel 77, which is located inside the sliding frame 76, has one end connected to the diversion pipe 73 and the other end connected to the outside. Through the guide channel 77, the diversion pipe 73 is communicated with the outside, and the diaphragm 19 can be sucked.

[0086] An intermediate pipe 72, which is arranged on the diversion pipe 73, has one end communicated with the drive pipe 70 and the other end communicated with the diversion pipe 73. Through the intermediate pipe 72, the drive pipe 70 and the diversion pipe 73 are communicated to ensure the flow of gas.

[0087] A control pipe 71, which is connected inside the diversion pipe 73, has one end connected to the outside and one end connected to the diversion pipe 73. The control pipe 7 performs necessary auxiliary control to control the air pressure inside the diversion pipe 73.

[0088] A control unit, which is connected to the diversion pipe 73;

[0089] An annular plate 8, which is fixedly connected to the chassis 1 and is in flat cooperation with the sliding frame 76. The annular plate 8 limits the sliding frame 76, forcing the first spring 74 to compress, so that the internal gas is discharged.

[0090] A limiting unit, which is connected to the guide cylinder 18. The limiting unit performs necessary limitation.

[0091] The limiting unit includes a guide rod 81 fixedly connected to the chassis 1. A moving frame 82 is slidably sleeved on the outer wall of the guide rod 81. One side of the moving frame 82 is fixedly connected to a second spring 80 fixedly connected to the chassis 1. Without interference, the second spring 80 forces the moving frame 82 to return to its position, and then blocks the diaphragm 19 to prevent the diaphragm 19 from falling. When the sliding frame 76 moves to this position, it forces the moving frame 82 to move, and the diaphragm 19 loses its limitation and the blanking is carried out.

[0092] The control unit includes:

[0093] A limiting block 83, which is fixedly connected to the diversion pipe 73. A drainage pipe 91 communicating with the diversion pipe 73 is connected inside the limiting block 83. The limiting block 83 performs necessary limitations so that a stable connection can be established between the drainage pipe 91 and the contact pipe 84.

[0094] A contact pipe 84, which is located inside the limiting block 83. One end of it is connected to the drainage pipe 91, and the other end is sleeved with a sealing block 85. The sealing block 85 is made of rubber material and can undergo a certain amount of deformation, thereby sealing the port of the contact pipe 84 to prevent the flow of gas.

[0095] A sliding plate 87, which is slidably connected to the limiting block 83 and fixedly connected to the sealing block 85. The sliding plate 87 can move under the drive of the limiting sleeve 90 from the outside, causing the sealing block 85 to move and lose the seal of the contact pipe 84.

[0096] A third spring 88, one end of which is fixedly connected to the sliding plate 87, and the other end is fixedly connected to a regulating plate 89. The outer wall of the regulating plate 89 is slidably sleeved with a limiting sleeve 90 fixedly connected to the sliding plate 87. Both sides of the limiting sleeve 90 are fixedly connected to fourth springs 86 fixedly connected to the limiting block 83. A contact rod in contact with the regulating plate 89 is provided on the dust-proof box 1. When contacting the regulating plate 89, it causes the regulating plate 89 to move against the third spring 88 while driving the limiting sleeve 90 to move, realizing the change of the sealing state.

[0097] One side of the guiding cylinder 18 is rotatably connected to a limiting door 78 through a spring hinge. A collecting door rotatably connected to the chassis 1 is provided below the guiding cylinder 18. The limiting door 78 performs certain limitations to ensure the execution of the work, and the collecting door is convenient for taking.

[0098] The accompanier 4 includes:

[0099] An accompanying block 40, at the bottom of which there is a connection groove 51. The connection groove 51 cooperates with the clamp 3. The accompanying block 40 provides necessary support, is positioned through the connection groove 51, and is then clamped by the clamp 3 to form a stable transportation environment.

[0100] A functional cavity 50, which is arranged inside the accompanying block 40. An air suction pump 49 is arranged inside it. The output end of the air suction pump 49 extends to the outside of the accompanying block 40. The functional cavity 50 provides necessary placement, and then the work requirements are realized through the air suction pump 49.

[0101] An air suction channel 48, which is located inside the accompanying block 40. One end of it communicates with the functional cavity 50, and the other end communicates with a sliding cavity 46 located inside the accompanying block 40. The gas that the air suction pump 49 needs to suck is absorbed through the air suction channel 48, and then necessary suction is carried out through the air suction nozzle 43 to form a negative pressure and achieve necessary limitations.

[0102] The fifth spring 47 has one end fixedly connected to the cavity wall of the sliding cavity 46, and the other end is connected to a suction nozzle 43 that is slidably sleeved in the sliding cavity 46. The fifth spring 47 provides a certain amount of buffering, enabling the suction nozzle 43 to slide.

[0103] The base plate 30 is placed on the suction nozzle 43, and sliding sleeves 42 are provided on all four sides thereof. The bottom end of the sliding sleeve 42 is fixedly connected to a sixth spring 45, and the other end of the sixth spring 45 is fixedly connected to a fixed cylinder 41 connected to the accompanying block 40. The base plate 30 is the device for applying the film. Through the limitation of the sixth spring 45 and the fixed cylinder 41, the sliding sleeve 42 can move to a certain extent to adapt to the progress of the work.

[0104] A plurality of auxiliary arcs 44 are provided and are fixedly connected to the accompanying block 40. The auxiliary arcs 44 provide certain assistance.

[0105] A plurality of triggers 52 are provided and are fixedly connected to the accompanying block 40. The triggers 52 cooperate with other devices to be triggered, causing the clamp 3 to release and the accompanying block 40 to drop.

[0106] An energizing block in contact with the connection groove 51 is provided on the clamp 3. A control cavity 53 is provided inside the accompanying block 40. A trigger point cooperating with the trigger 52 is provided on one side of the chassis 1. The energizing block supplies power to the inside of the accompanying block 40, and the trigger point triggers the trigger 52.

[0107] The cleaning and drying mechanism includes:

[0108] The feeding roller 2 is rotatably connected to the chassis 1 and is in transmission connection with the transmission mechanism. The feeding roller 2 is connected to an external feeding device to add water to the substrate, and then the glue is preliminarily dried through the preheater 7, reducing overflow while ensuring subsequent bonding.

[0109] The preheater 7 is fixedly connected to the chassis 1 and is located above the accompanier 4;

[0110] The first dryer 10 is fixedly connected to the chassis 1 and is located above the accompanier 4. The first dryer 10 performs initial drying to ensure the drying of the colloid and the firmness of the bonding.

[0111] The sliding rail 12 is fixedly connected to the chassis 1 and is located on the lower side of the chassis 1. The sliding rail provides guidance, enabling the accompanier 2 to move along the sliding rail 12. At the same time, through the gravitational potential energy and the push of water, the other end moves out.

[0112] The circulating pump 15 is fixedly connected to one side of the chassis 1. Its input end is connected to the filter 14, and one side of the filter 14 is connected to the suction pipe 13 located inside the chassis 1. The output end of the circulating pump 15 is connected to the return pipe 11 connected to the chassis 1. The circulating pump 15 extracts the liquid at the bottom, then filters it through the filter 14, and then sprays it out through the return pipe 11 to promote the water flow and circulate the liquid.

[0113] The drain pipe 17 is fixedly connected to the chassis 1 and is located above the sliding rail 12. Above the drain pipe 17, there is a U-shaped transport channel 32 fixedly connected to the chassis 1. The drain pipe 17 returns the liquid that may drip.

[0114] During operation, the accompanier 4 with the bottom plate 30 is placed on the fixture 3. Then, when passing through the feeding roller 2, glue is applied to the surface of the bottom plate 30. After that, it passes through the preliminary drying of the preheater 7 to reduce the fluidity of the glue. Then it reaches below the blanking device 9. Through the limitation of the annular plate 8 and the feeding of the blanking device 9, film sticking is achieved. Then, after being dried again by the first dryer 10, through triggering, the accompanier 4 is separated from the fixture 3 and falls into the sliding rail 12. Then, under the action of gravity and the thrust of the liquid, it is discharged from the other end of the sliding rail 12. During this process, the excess glue is discharged, then enters one side of the chassis 1 for draining, and the work is completed. During this period, driven by the motor 22 and the transmission of the transmission component 23 and the sheave mechanism 24, the transmission shaft 5 rotates periodically. Then, through transmission, the intermediate shaft 27, the transmission wheel 28, the missing gear 25, and the driving tooth 21 are driven to rotate, further driving the driving pipe 70 to rotate. During this process, the guide pipe 73 and the sliding frame 76 are driven to rotate, so that the sliding frame 76 contacts the annular plate 8. During the contact process, the sliding frame 76 moves against the first spring 74, reducing the space between the guide pipe 73 and the sliding frame 76. The gas inside is discharged through the control pipe 71. Then, when reaching the top, the limitation is lost, and it sucks air from the outside. Then, under the action of the external atmospheric pressure and the first spring 74, it is pressed onto the diaphragm 19 and sucks the diaphragm 19. During the downward rotation process, it maintains this state until reaching the bottom. Through triggering, the regulation plate 89 moves, further driving the sliding plate 87 and the sealing block 85 to move, so that the external gas enters the guide pipe 73 through the drainage pipe 91 to achieve stable air pressure. Under the action of the first spring 74, the diaphragm 19 is pressed onto the bottom plate 30 with glue to achieve patch sticking. At the same time, with the transmission of the gear and the sheave mechanism, periodic and stable patch sticking is achieved.

[0115] Embodiment 2:

[0116] The second dryer 31 is located above the transport path 32 and is fixedly connected to the chassis 1. The second dryer 31 performs secondary drying to ensure overall dryness, and the transport path 21 is for transportation.

[0117] An air suction mechanism 20 is connected to one side of the chassis 1, and a filling pipe is fixedly connected to one side of the chassis 1. The air suction mechanism performs negative pressure air suction to achieve high pressure inside the chassis, prevent dust from overflowing, and reduce dust pollution. The filling pipe facilitates the addition of other liquids.

[0118] The produced device is placed on the transport path 32 manually or mechanically, and then dried by the second dryer 31 to complete the production process.
