Description

Technical Field

[0001] This utility model relates to the field of adhesive application technology, and in particular to a double-sided adhesive application machine. Background Technology

[0002] In the production of circuit boards, battery electrodes, and other boards or sheets, adhesive application is often required, sometimes even double-sided. A Chinese patent application (application number 202111405325.4) discloses an electrode adhesive application device, an electrode adhesive application process, a battery cell, a battery, and an electrical device. The electrode adhesive application device includes an adhesive application mechanism used to apply adhesive to the electrode along its transport direction, forming an adhesive application area on the electrode. This adhesive application area is located along the width of the electrode at both edges, and the electrode has a coating area in the middle. The adhesive application area at least partially overlaps with the coating area and extends beyond the electrode along its width. While this patent achieves double-sided adhesive application, it cannot position moving electrodes and can only apply adhesive continuously, unable to cut the adhesive tape between adjacent electrodes. Therefore, its shortcomings are significant, and a solution is urgently needed. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a double-sided adhesive applicator.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A double-sided adhesive applicator includes a machine base, a roller pressing and feeding mechanism, a roller shaft feeding mechanism, a double-sided adhesive applicator, and a cutting mechanism. The machine base has a lower support, and the roller shaft feeding mechanism is mounted on the top of the lower support. A space is provided between the bottom surface of the roller shaft feeding mechanism and the top surface of the machine base. An upper support is mounted on the frame of the roller shaft feeding mechanism. The roller shaft feeding mechanism has, along the feeding direction, a feeding area, an adhesive applicator area, a roller pressing and feeding area, a cutting area, and an output area. The double-sided adhesive applicator is positioned corresponding to the adhesive applicator area. The roller pressing and feeding mechanism is located in the middle of the roller shaft feeding mechanism and corresponds to the roller pressing and feeding area. The cutting mechanism is mounted on the upper support, located above the roller shaft feeding mechanism, and corresponds to the cutting area. The cutting mechanism should be configured such that its cutting end can extend between two adjacent rollers of the roller feeding mechanism. The double-sided adhesive applicator includes a lower adhesive applicator mounted on the machine base and located within the accommodating space, and an upper adhesive applicator mounted on the upper support and symmetrically arranged with the lower adhesive applicator. When the board conveyed by the roller feeding mechanism passes the adhesive applicator ends of the upper and lower adhesive applicators, the upper and lower adhesive applicators respectively apply adhesive to the upper and lower surfaces of the board. The cutting mechanism is used to cut the tape between two adjacent boards. A positioning mechanism and a material sensor are provided at the board feeding area of ​​the roller feeding mechanism. The material sensor is electrically connected to the positioning mechanism, and the material sensor and the positioning mechanism are used to position the board at the board feeding area.

[0006] Furthermore, two feeding sensors are spaced apart on the bottom surface of the roller feeding mechanism. Both feeding sensors are located in the board feeding area. The two feeding sensors are electrically connected to the roller pressing feeding mechanism and the roller feeding mechanism, respectively. One feeding sensor is used to detect the rear edge of the board being glued by the double-sided adhesive applicator, and the other feeding sensor is used to detect the front edge of the board that has moved from the board feeding area to the adhesive applicator area.

[0007] Furthermore, a cutting sensor is provided on the bottom surface of the roller feeding mechanism. The cutting sensor is located in the cutting area and is electrically connected to the cutting mechanism, the roller pressing feeding mechanism and the roller feeding mechanism respectively. The cutting sensor is used to detect the rear edge of the plate that has moved from the cutting area to the plate exit area. The cutting sensor is exposed between two adjacent rollers of the roller feeding mechanism, and the cutting end of the cutting mechanism is offset from the cutting sensor.

[0008] Furthermore, there are two double-sided adhesive applicators, which are arranged side by side.

[0009] Furthermore, the positioning mechanism includes a blocking ring, a guide ring, and a side-push positioning module. The blocking ring is located at one end of the roller of the roller feeding mechanism, and several guide rings are respectively located at the other end of several rollers of the roller feeding mechanism located at the feeding end of the feeding area. A guide plate channel is formed between the blocking ring and the guide ring. The side-push positioning module is installed on the frame of the roller feeding mechanism and located at the discharge end of the feeding area. The side-push positioning end of the side-push positioning module is positioned opposite to the blocking ring at a distance. Several guide rings and the side-push positioning module are arranged along the feeding direction of the roller feeding mechanism.

[0010] Furthermore, the side-push positioning module includes a mounting plate installed on the frame of the roller feeding mechanism, a positioning cylinder installed on the mounting plate, a side-push positioning plate installed on the piston rod of the positioning cylinder, and a positioning sensor embedded in the side-push positioning plate. The positioning sensor is electrically connected to the positioning cylinder. The positioning sensor is used to detect the plate, and the positioning cylinder is used to drive the side-push positioning plate to move closer to or away from the corresponding blocking ring.

[0011] Furthermore, both the upper and lower adhesive application mechanisms include a roll frame, a rotating shaft rotatably connected to the roll frame, a tensioner disposed on the roll frame and used to provide tension to the rotating shaft, an air shaft fitted onto one end of the rotating shaft, a guide roller rotatably connected to the roll frame and located on the lower side of the air shaft, a lifting cylinder mounted on the roll frame, a guide component mounted on the piston rod of the lifting cylinder, and an adhesive application pressure roller rotatably connected to the tape exit end of the guide component. The guide component has a guide channel. The adhesive application pressure rollers of the upper and lower adhesive application mechanisms are arranged vertically and vertically correspondingly and located between two adjacent rollers of the roller feeding mechanism.

[0012] Furthermore, both the upper and lower adhesive application mechanisms also include a position adjustment module. The roll rack is installed at the position adjustment end of the position adjustment module, the position adjustment module of the upper adhesive application mechanism is installed on the upper support, and the position adjustment module of the lower adhesive application mechanism is installed on the top surface of the machine.

[0013] Furthermore, the roller feeding mechanism is equipped with two sets of counter-pressure rollers. One set of counter-pressure rollers is located on the feeding side of the double-sided adhesive applicator, and the other set of counter-pressure rollers is located on the side of the cutting mechanism away from the roller feeding mechanism.

[0014] The beneficial effects of this utility model are as follows: In practical applications, the board is placed on the feeding area of ​​the roller feeding mechanism, which then conveys the board. The moving board passes through the double-sided adhesive applicator, that is, it passes between the adhesive applicator ends of the upper and lower adhesive applicators. During this process, the upper and lower adhesive applicators apply adhesive to the upper and lower surfaces of the board, respectively, to achieve double-sided adhesive application. As the roller feeding mechanism continues to convey the board to the double-sided adhesive applicator, the double-sided adhesive applicator continuously applies double-sided adhesive to the moving boards. Furthermore, while the double-sided adhesive applicator is applying double-sided adhesive to the board, the glued board is then conveyed by the roller pressing feeding mechanism. The roller feeding mechanism rolls and conveys the glued boards. During this process, the roller feeding mechanism not only presses the glued tape tightly onto the boards, but also improves the stability of the double-sided glue application device, ensuring that the boards do not loosen during the glue application process and improving the quality of the glue application. As the roller feeding mechanism conveys the glued boards, when the cutting end of the cutting mechanism is located between two adjacent glued boards, the roller feeding mechanism and the roller pressing feeding mechanism stop conveying the boards. The cutting end of the cutting mechanism cuts the tape between the two adjacent glued boards, and the cut glued boards are output through the roller feeding mechanism. This utility model features an automated positioning and conveying system for plates. It can continuously apply adhesive to both sides of plates and cut the adhesive tape between adjacent plates after application, thus improving the efficiency of applying adhesive to the plates. Furthermore, the plates after application are conveyed by a roller pressing and feeding mechanism, which ensures that the adhesive tape adheres firmly to both the top and bottom surfaces of the plates, thereby improving the quality of the adhesive application.

Detailed Implementation

[0022] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0023] like Figures 1 to 5 As shown, this utility model provides a double-sided adhesive applicator, which includes a machine base 1, a roller pressing and feeding mechanism 2, a roller shaft feeding mechanism 3, a double-sided adhesive applicator 4, and a cutting mechanism 5. The machine base 1 is provided with a lower support 6, and the roller shaft feeding mechanism 3 is mounted on the top of the lower support 6. A receiving space 7 is provided between the bottom surface of the roller shaft feeding mechanism 3 and the top surface of the machine base 1. An upper support 8 is mounted on the frame of the roller shaft feeding mechanism 3. The roller shaft feeding mechanism 3 is provided with a board feeding area, an adhesive applicator area, a roller pressing and feeding area, a cutting area, and a board output area in sequence along the board feeding direction. The double-sided adhesive applicator 4 is provided corresponding to the adhesive applicator area. The roller pressing and feeding mechanism 2 is located in the middle of the roller shaft feeding mechanism 3 and corresponds to the roller pressing and feeding area. The cutting mechanism 5 is mounted on the upper support 8. The cutting mechanism 5 is located above the roller feeding mechanism 3 and is positioned corresponding to the cutting area. The cutting end of the cutting mechanism 5 can extend between two adjacent rollers of the roller feeding mechanism 3. The double-sided adhesive applicator 4 includes a lower adhesive applicator 9 mounted on the machine base 1 and located in the accommodating space 7, and an upper adhesive applicator 10 mounted on the upper support 8 and symmetrically arranged with the lower adhesive applicator 9. When the board conveyed by the roller feeding mechanism 3 passes the adhesive applicator end of the upper adhesive applicator 10 and the adhesive applicator end of the lower adhesive applicator 9, the upper adhesive applicator 10 and the lower adhesive applicator 9 respectively apply adhesive to the upper and lower surfaces of the board. The cutting mechanism 5 is used to cut the tape between two adjacent boards.

[0024] In practical applications, the board is placed in the feeding area of ​​the roller feeding mechanism 3. The roller feeding mechanism 3 conveys the board, and the moving board passes through the double-sided adhesive applicator 4. That is, the moving board passes between the adhesive applicator ends of the upper adhesive applicator 10 and the lower adhesive applicator 9. During this process, the upper adhesive applicator 10 and the lower adhesive applicator 9 apply adhesive to the upper and lower surfaces of the board, respectively, to achieve double-sided adhesive application. As the roller feeding mechanism 3 continues to convey the board to the double-sided adhesive applicator 4, the double-sided adhesive applicator 4 continuously applies double-sided adhesive to the moving boards. While the double-sided adhesive applicator 4 is applying double-sided adhesive to the board, the glued board passes through the roller pressing and feeding mechanism 2. The feeding mechanism 2 rolls and conveys the glued boards. During this process, the rolling feeding mechanism 2 not only presses the glued tape tightly onto the boards, but also improves the stability of the double-sided glued board device 4 in applying glue to both sides of the boards. This ensures that the boards do not loosen during the glue application process, thus improving the quality of the glue application. As the roller feeding mechanism 3 conveys the glued boards, when the cutting end of the cutting mechanism 5 is located between two adjacent glued boards, the roller feeding mechanism 3 and the rolling feeding mechanism 2 stop conveying the boards. The cutting end of the cutting mechanism 5 cuts the tape between the two adjacent glued boards, and the cut glued boards are output via the roller feeding mechanism 3.

[0025] In this embodiment, a positioning mechanism 11 and a material sensor are provided in the feeding area of ​​the roller feeding mechanism 3. The material sensor is electrically connected to the positioning mechanism 11. The material sensor and the positioning mechanism 11 are used to position the board in the feeding area.

[0026] In practical applications, the roller feeding mechanism 3 conveys the board. When the incoming material sensor detects the board, it sends a signal to the positioning mechanism 11, which positions the board and improves the positional accuracy of the board. This improves the positional accuracy of the board from the board feeding area to the adhesive application area, and thus improves the quality of double-sided adhesive application on the board.

[0027] This utility model features an automated positioning and conveying system for plates. It can continuously apply adhesive to both sides of the plates and cut the tape between adjacent plates after application, thus improving the efficiency of applying adhesive to the plates. After application, the plates are conveyed by a roller pressing and feeding mechanism 2, which ensures that the tape adheres firmly to both the top and bottom surfaces of the plates, thereby improving the quality of the adhesive application.

[0028] In this embodiment, two feeding sensors 12 are arranged at intervals on the bottom surface of the roller feeding mechanism 3. Both feeding sensors 12 are located in the board feeding area. The two feeding sensors 12 are electrically connected to the roller feeding mechanism 2 and the roller feeding mechanism 3, respectively. One feeding sensor 12 is used to detect the rear edge of the board to be glued by the double-sided adhesive applicator 4, and the other feeding sensor 12 is used to detect the front edge of the board that has moved from the board feeding area to the adhesive applicator area.

[0029] In practical applications, the roller feeding mechanism 3 transports the boards in the board feeding area to the double-sided adhesive applicator 4. The upper adhesive applicator 10 and the lower adhesive applicator 9 of the double-sided adhesive applicator 4 apply adhesive to the upper and lower surfaces of the boards, respectively. When one feeding sensor 12 detects the rear edge of the board being glued or the rear edge of the board about to be glued, the board being glued or the board after glue application is in the roller feeding mechanism 2, and the other feeding sensor 12 cannot detect the front edge of the next board to be glued, both feeding sensors 12 send feedback signals to the roller feeding mechanism 2, causing the roller feeding mechanism 2 to stop working. At this time, the roller feeding mechanism 2 presses the board being glued or the board after glue application, so that the board is glued to the roller feeding mechanism 2. If the roller feeding mechanism 3 slips, the board will be slowly conveyed or unable to be conveyed until another board feeding sensor 12 detects the front edge of the next board to be glued. The board feeding sensor 12 then sends a signal to the roller feeding mechanism 2, causing the roller feeding mechanism 2 to re-feed the glued board. This structural design ensures that the spacing between two adjacent boards after gluing is constant, avoiding the phenomenon of excessive spacing or uneven spacing between two adjacent boards after gluing due to untimely supply of subsequent boards, thus preventing waste of tape. It also helps the subsequent cutting mechanism 5 to accurately cut the tape between two adjacent boards, reducing the probability of the cutting mechanism 5 cutting the board.

[0030] In this embodiment, a cutting sensor 13 is provided on the bottom surface of the roller feeding mechanism 3. The cutting sensor 13 is located in the cutting area and is electrically connected to the cutting mechanism 5, the roller feeding mechanism 2 and the roller feeding mechanism 3 respectively. The cutting sensor 13 is used to detect the rear edge of the plate that has moved from the cutting area to the plate exit area. The cutting sensor 13 is exposed between two adjacent rollers of the roller feeding mechanism 3. The cutting end of the cutting mechanism 5 is offset from the cutting sensor 13.

[0031] In practical applications, during the process of the board moving from the cutting area to the board exit area, when the cutting sensor 13 detects the rear edge of the board, the cutting sensor 13 sends a signal to the roller feeding mechanism 2, the roller feeding mechanism 3, and the cutting mechanism 5, causing the roller feeding mechanism 2 and the roller feeding mechanism 3 to stop working. At this time, the cutting end of the cutting mechanism 5 is located between two adjacent boards after adhesive application. The cutting end of the cutting mechanism 5 descends and cuts the adhesive tape between the two adjacent boards. After the cutting mechanism 5 completes one cutting action, the roller feeding mechanism 2 and the roller feeding mechanism 3 continue to work, and the board in the board exit area can be sent out by the roller feeding mechanism 3.

[0032] To ensure the accuracy of the cutting mechanism 5 in cutting the tape between two adjacent boards, preferably, there are two cutting sensors 13. Both cutting sensors 13 are located within the cutting area and are electrically connected to the cutting mechanism 5, the roller feeding mechanism 2, and the roller feeding mechanism 3, respectively. One cutting sensor 13 detects the rear edge of the board moving from the cutting area to the exit area, and the other cutting sensor 13 detects the front edge of the board in the cutting area. The two cutting sensors 13 are exposed between two adjacent rollers of the roller feeding mechanism 3, and the cutting end of the cutting mechanism 5 is located between the two cutting sensors 13. In practical applications, when one cutting sensor 13 detects the rear edge of the previous board (the board in the exit area) and the other cutting sensor 13 detects the front edge of the next board (the board in the cutting area), it proves that the cutting end of the cutting mechanism 5 is located precisely between the tapes between the two adjacent boards, effectively preventing the cutting end of the cutting mechanism 5 from colliding with the boards.

[0033] In this embodiment, there are two double-sided adhesive applicators 4, which are arranged side by side. In practical applications, as the roller feeding mechanism 2 and the roller feeding mechanism 3 convey the board, the two double-sided adhesive applicators 4 simultaneously apply adhesive to both sides of the board, so that the two double-sided adhesive applicators 4 respectively apply adhesive to the upper and lower sides of the two edges of the board.

[0034] In this embodiment, the positioning mechanism 11 includes a blocking ring 14, a guide ring 15, and a side-push positioning module 16. The blocking ring 14 is disposed at one end of the roller of the roller feeding mechanism 3. Several guide rings 15 are respectively disposed at the other end of several rollers of the roller feeding mechanism 3 located at the feeding end of the feeding area. A guide plate channel is formed between the blocking ring 14 and the guide ring 15. The side-push positioning module 16 is mounted on the frame of the roller feeding mechanism 3 and located at the discharge end of the feeding area. The side-push positioning end of the side-push positioning module 16 is disposed opposite to the blocking ring 14 at a distance. Several guide rings 15 and the side-push positioning module 16 are arranged along the feeding direction of the roller feeding mechanism 3.

[0035] In practical applications, as the roller feeding mechanism 3 conveys the plate, the plate first moves in the guide plate channel between the guide ring 15 and the blocking ring 14. When the incoming material sensor detects the plate, the incoming material sensor sends a signal to the side-push positioning module 16. The side-push positioning end of the side-push positioning module 16 pushes the plate to abut against the blocking ring 14, so that the side of the plate moves against the blocking ring 14, thereby realizing the positioning and conveying of the plate.

[0036] In this embodiment, the side-push positioning module 16 includes a mounting plate 17 mounted on the frame of the roller feeding mechanism 3, a positioning cylinder 18 mounted on the mounting plate 17, and a side-push positioning plate 19 mounted on the piston rod of the positioning cylinder 18. The positioning cylinder 18 is used to drive the side-push positioning plate 19 to move closer to or further away from the corresponding blocking ring 14. The material sensor is embedded in the side-push positioning plate 19 or mounted on the frame of the roller feeding mechanism 3.

[0037] In practical applications, when the material sensor detects the plate, it sends a signal to the positioning cylinder 18, causing the piston rod of the positioning cylinder 18 to extend and drive the side-push positioning plate 19 to move horizontally. This causes the side-push positioning plate 19 to push the plate against the blocking ring 14, thereby positioning the plate.

[0038] In this embodiment, both the upper adhesive applicator 10 and the lower adhesive applicator 9 include a roll holder 20, a rotating shaft 21 rotatably connected to the roll holder 20, a tensioner 23 disposed on the roll holder 20 and used to provide tension to the rotating shaft 21, an air shaft 22 fitted onto one end of the rotating shaft 21, a guide roller 24 rotatably connected to the roll holder 20 and located on the lower side of the air shaft 22, a lifting cylinder 25 mounted on the roll holder 20, a guide component 26 mounted on the piston rod of the lifting cylinder 25, and an adhesive applicator pressure roller 27 rotatably connected to the tape exit end of the guide component 26. The guide component 26 has a guide channel. The adhesive applicator pressure roller 27 of the upper adhesive applicator 10 and the adhesive applicator pressure roller 27 of the lower adhesive applicator 9 are arranged vertically correspondingly and located between two adjacent rollers of the roller feeding mechanism 3. Specifically, the tensioner 23 can be an existing device such as a hysteresis tensioner 23, which will not be described in detail here.

[0039] In practical applications, the tape roll is mounted on the air shaft 22. The air shaft 22 expands to clamp the inner wall of the tape roll's paper tube, thus fixing the tape roll. The tape roll passes through the guide roller 24 and then through the guide channel of the guide member 26. The tape output from the guide channel is located on the feeding side of the adhesive roller 27. Before the machine is started, the free ends of the tape on the upper adhesive mechanism 10 and the lower adhesive mechanism 9 are first pasted together. As the roller feeding mechanism 3 conveys the board, the board will carry the pasted tape into the gap between the two adhesive rollers 27. The adhesive rollers 27 will press the tape onto the side of the board to achieve double-sided adhesive application on the upper and lower sides of the board. As the tape roll rotates with the air shaft 22 and the rotating shaft 21, the tensioner 23 provides tension to the rotating shaft 21 to ensure that the tape roll maintains a constant tension. The piston rod of the lifting cylinder 25 extends and retracts to drive the guide belt 26 and the adhesive application roller 27 to rise and fall, thereby adjusting the gap between the adhesive application roller 27 of the upper adhesive application mechanism 10 and the adhesive application roller 27 of the lower adhesive application mechanism 9, so as to meet the adhesive application of boards or tapes of different thicknesses.

[0040] Specifically, the surface of the guide pulley 24 is provided with a non-stick coating so that even if the adhesive side of the tape wraps around the guide pulley 24, it will not stick to the guide pulley 24.

[0041] Specifically, the tensioner 23 can use an existing tensioning mechanism, which will not be described in detail here.

[0042] In this embodiment, both the upper adhesive applicator 10 and the lower adhesive applicator 9 further include a position adjustment module 28. The roll holder 20 is mounted on the position adjustment end of the position adjustment module 28, the position adjustment module 28 of the upper adhesive applicator 10 is mounted on the upper support 8, and the position adjustment module 28 of the lower adhesive applicator 9 is mounted on the top surface of the machine base 1. In practical applications, the position adjustment module 28 can adjust the position of the roll holder 20, thereby adjusting the adhesive application position of the tape. This facilitates aligning the tape with the adhesive application position of the board to be glued, and allows for adjustment of the tape position according to different board specifications to meet the adhesive application requirements of different specifications.

[0043] In this embodiment, the roller feeding mechanism 3 is provided with two sets of counter-pressure roller groups 29; one set of counter-pressure roller groups 29 is located on the adhesive feeding side of the double-sided adhesive applicator 4, and the distance between this set of counter-pressure roller groups 29 and the roller feeding mechanism 2 is less than the length of a plate; the other set of counter-pressure roller groups 29 is located on the side of the cutting mechanism 5 away from the roller feeding mechanism 2, and the distance between this set of counter-pressure roller groups 29 and the roller feeding mechanism 2 is less than the length of a plate.

[0044] In practical applications, as the roller feeding mechanism 3 conveys the board, the board in the board feeding area is pressed by a set of pressure rollers 29 and then conveyed to the adhesive application area. This improves the quality of double-sided adhesive application by the double-sided adhesive application device 4. When the double-sided adhesive application device 4 applies adhesive to the board, either a set of pressure rollers 29 presses the board, or a set of pressure rollers 29 and the roller feeding mechanism 2 jointly press the board, or the roller feeding mechanism 2 presses the board. This ensures that the board is always pressed during the adhesive application process, improving the stability of the board movement and thus improving the quality of adhesive application. During the process of the roller feeding mechanism 2 conveying the board from the roller feeding area to the cutting area, the roller feeding mechanism 2 always presses the board. When the board moves to the cutting area, another set of pressure rollers 29 presses the board, ensuring that the board is always pressed. This improves the stability and quality of the cutting end of the cutting mechanism 5 cutting the tape between two adjacent boards.

[0045] Specifically, the cutting mechanism 5 includes a cutting cylinder 30 mounted on the upper support 8, a lifting plate 31 mounted on the piston rod of the cutting cylinder 30, and a cutting blade 32 mounted on the lifting plate 31. The cutting blade 32 is located between two adjacent rollers of the roller feeding mechanism 3 and is inclined. The lifting plate 31 is located above the roller feeding mechanism 3. The cutting cylinder 30 is used to drive the lifting plate 31 to rise and fall. The cutting sensor 13 is electrically connected to the cutting cylinder 30. In practical applications, when the cutting sensor 13 detects the rear edge of the board, the cutting sensor 13 sends a signal to the cutting cylinder 30, causing the piston rod of the cutting cylinder 30 to extend and drive the lifting plate 31 and the cutting blade 32 to fall, so that the cutting blade 32 cuts the tape between two adjacent boards.

[0046] Specifically, the roller pressing and feeding mechanism 2 includes a lower roller pressing and feeding roller 33 rotatably connected to the middle of the frame of the roller pressing and feeding mechanism 3, two seats 34 respectively mounted on the two opposite side walls of the frame of the roller pressing and feeding mechanism 3, two sliders 35 respectively slidably connected to the two seats 34, an upper roller pressing and feeding roller 36 rotatably connected between the two sliders 35, two disassembly plates 37 respectively detachably mounted on the top surface of the two seats 34, two lifting adjustment components 38 respectively mounted on the two disassembly plates 37, and a rotation driver mounted on the machine base 1 or the frame of the roller pressing and feeding mechanism 3. The rotation driver is used to drive the lower roller pressing and feeding roller 33 to rotate. The upper roller pressing and feeding roller 36 is arranged vertically and vertically corresponding to the lower roller pressing and feeding roller 33. The two lifting adjustment components 38 are respectively arranged one-to-one with the two sliders 35. The lifting adjustment components 38 are used to adjust the height position of the sliders 35 on the seats 34. Specifically, the rotary drive can adopt a transmission structure of motor, synchronous belt and synchronous pulley, and the lifting adjustment assembly 38 can adopt an existing adjusting bolt assembly, which will not be described in detail here.

[0047] In practical applications, the rotary driver drives the lower roller 33 to rotate, and the rotating lower roller 33 cooperates with the upper roller 36 to drive the plate to move. According to the thickness of different plates, the slider 35 is adjusted by the lifting adjustment component 38 to lift and slide. The sliding slider 35 drives the upper roller 36 to lift and adjust, so as to adjust the gap between the upper roller 36 and the lower roller 33 to meet the needs of conveying plates of different thicknesses. When it is necessary to disassemble the upper roller 36, simply remove the disassembly plate 37 from the base 34 to remove the upper roller 36 from the base 34.

[0048] Specifically, the inner wall of the base 34 is recessed from top to bottom with a groove 39, and the slider 35 is slidably connected to the inner wall of the groove 39. The disassembly plate 37 is covered on the top end of the groove 39. During the lifting and lowering movement of the slider 35, the slider 35 slides up and down along the groove 39, which improves the stability of the lifting and lowering movement of the slider 35.

[0049] Specifically, the pressure roller group 29 can adopt the structure of the roller pressing and feeding mechanism 2 after removing the rotation driver, and the pressure roller group 29 and the roller feeding mechanism 3 share a common driving source.

[0050] All technical features in this embodiment can be freely combined according to actual needs.

[0051] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
