Description

Technical Field

[0001] This application relates to the field of cardboard cutting and processing, and in particular to a highly stable board support or comb pushing mechanism. Background Technology

[0002] Corrugated cardboard production mainly uses computer-controlled slitting and trimming machines for cutting, which not only has high production efficiency but also high cutting accuracy. The cutting quality of corrugated cardboard by the computer-controlled slitting and trimming machine is mainly determined by the board support (comb) that cooperates with the cutting wheel. The more fully the board support supports the corrugated cardboard, the smaller the rough edges after cutting. During the cardboard cutting process, the cutting wheel engages between adjacent comb teeth to cut the cardboard.

[0003] Chinese utility model patent CN221756153U discloses a board tray or comb pushing device, relating to the field of cardboard cutting and processing. It includes a mounting base and a push block slidably connected to the mounting base. The mounting base has a board drop groove, and the push block slides closer to or away from the drop groove. The mounting base is equipped with a driving component to move the push block. When the comb teeth on the board tray / comb are worn, the driving component drives the push block to move closer to the drop groove. The speed and distance of the push block's movement can be adjusted according to actual needs, allowing the intact board tray / comb to move to the cutting wheel and engage with it. This eliminates the need to stop the machine to replace the board tray / comb, saving replacement time and reducing the impact on cardboard cutting efficiency. Furthermore, the same batch of board trays / combs can be reused multiple times among multiple computerized slitting and trimming machines, improving the utilization rate of the board trays / combs.

[0004] In actual use, gaps may appear between the board support and the comb, causing the cutting wheel to not be positioned within the comb teeth during cutting. This can easily result in rough edges after the cardboard is cut, affecting the quality of the cardboard cutting. Summary of the Invention

[0005] In order to ensure the board support is firmly positioned during corrugated cardboard production and improve the cutting quality of the cardboard, this application provides a highly stable board support or comb pushing mechanism.

[0006] This application provides a highly stable plate support or comb pushing mechanism, which adopts the following technical solution: A high-stability plate support or comb pushing mechanism includes a mounting base and a slide rail on the mounting base for sliding the plate support. One end of the slide rail is a loading end and the other end is a unloading end. The mechanism also includes a first driving structure that drives the plate support to move towards the unloading end and a second driving structure that drives the plate support to move towards the loading end. When a row of plate supports on the slide rail is in operation, the first driving structure and the second driving structure clamp the row of plate supports on the slide rail.

[0007] By adopting the above technical solution, the board support in this solution can be replaced by a comb. When in use, the mounting base is installed on the computer slitting and trimming machine. During normal operation, the first drive structure and the second drive structure clamp a row of board supports on the slide rail, so that there is no gap between the board supports, thereby making the cutting wheel stably located in the comb teeth to cut the cardboard, resulting in good cardboard cutting quality and no burrs. After the board tray wears out, the first and second drive structures, after being set by the control system, slide a certain distance toward the unloading end at regular intervals. The distance can be set by the control system. The cutting wheel cuts the cardboard between different comb teeth. When the sliding distance is close to that of one board tray, the control system controls the second drive structure to release the board tray. After the second drive structure releases the board tray, a gap of at least one board tray is left between the second drive structure and the unloading end of the slide rail. The first drive structure pushes one board tray away from the slide rail, so that it falls down, allowing the worn board tray to be unloaded. Then, the staff uses the control system to move the first drive structure away from the slide rail by at least one plate support gap. After the plate support is loaded, the control system controls the first drive structure and the second drive structure to re-clamp the row of plate supports on the slide rail, so that the row of plate supports abut against each other.

[0008] Optionally, the mounting base is provided with a drop plate groove, which is used for plate support and material unloading, and the drop plate groove is located on one side of the material unloading end of the slide rail.

[0009] By adopting the above technical solution, the drop groove is used to reach the plate support after it is removed from the slide rail, so that the plate support can move away from the slide rail. At this time, the second drive structure can easily clamp the row of plate supports on the slide rail again.

[0010] Optionally, the first drive structure includes a first pusher and a first push block of a sliding connection mounting base, wherein the first pusher drives the first push block to slide toward or away from the unloading end.

[0011] By adopting the above technical solution, when the plate support is worn, the first pushing member drives the first pushing block to slide a certain distance towards the side of the drop plate groove, so that the cutting wheel is located in another toothed comb for cutting, resulting in a good cutting effect.

[0012] Optionally, the second drive structure includes a second pusher and a second push block of a sliding connection mounting base, wherein the second pusher drives the second push block to slide toward or away from the feeding end.

[0013] By adopting the above technical solution, when a row of plate supports is working, the second pusher drives the second push block to press against the plate support, preventing the cutter from not being located within the comb teeth when cutting.

[0014] Optionally, the slide rail includes a guide block disposed on the mounting base, and a sliding groove is provided on the plate support to accommodate the guide block. The sliding groove fits with the guide block, and the plate support slides along the length direction of the guide block.

[0015] By adopting the above technical solution, the guide block and sliding groove make the plate support slide stably, while the first driving structure and the second driving structure stably abut against the plate support.

[0016] Optionally, the slide rail further includes a pressure block disposed on the mounting base, a receiving groove is provided between the guide block and the pressure block, the end of the plate support is slidably connected in the receiving groove, the pressure block slidably contacts the upper surface of the plate support, and the pressure block is used to restrict the plate support to be located in the receiving groove.

[0017] By adopting the above technical solution, the pressure block further stabilizes the sliding of the plate support, and restricts the sliding of the plate support along a path perpendicular to the guide block.

[0018] Optionally, the first push block includes a first sliding part and a first push plate part. The first sliding part has a first through groove, the length direction of which is parallel to the sliding direction of the first push block. The mounting base is provided with at least one first limiting post. The at least one first limiting post is horizontally distributed along the sliding direction of the first push block, and the first limiting post passes through the first through groove. The first limiting post is provided with a first limiting member, and the first sliding part is limited between the first limiting member and the mounting base.

[0019] By adopting the above technical solution, the first limiting post abuts against the inner wall of the first through groove, thereby limiting the movement stability of the first push block and preventing the first limiting post from disengaging from the first through groove.

[0020] Optionally, the second push block includes a second sliding part and a second push plate part. The second sliding part is provided with a second through groove. The length direction of the second through groove is parallel to the sliding direction of the second push block. The mounting base is provided with at least one second limiting post. The at least one second limiting post is horizontally distributed along the sliding direction of the second push block, and the second limiting post passes through the second through groove. The second limiting post is provided with a second limiting member. The second sliding part is limited between the second limiting member and the mounting base.

[0021] By adopting the above technical solution, when the second pusher drives the second push plate to slide, the second limiting post abuts against the inner wall of the second through groove, thereby limiting the second sliding part, improving the sliding stability of the second sliding part, and the second limiting member prevents the second limiting post from disengaging from the second through groove.

[0022] Optionally, the plate support is symmetrically arranged on both sides.

[0023] By adopting the above technical solution, the board tray can be used on both sides. When one side of the board tray is worn, the board tray can be replaced on another computerized longitudinal cutting and trimming machine and flipped to the other side for continued use. The wear degree of the board trays on one computerized longitudinal cutting and trimming machine is similar.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. The control system controls the first and second drive structures to clamp a row of plate supports on the slide rail, so that the row of plate supports abut against each other. When the cutting wheel cuts, it is located inside the comb teeth, which makes it less likely to produce burrs and improves the cutting quality of the cardboard. 2. The pressure block stabilizes the sliding of the plate support; 3. The tray is double-sided. When one side of the tray is worn, it can be flipped to the other side for continued use.

The second sliding part 411 is slidably connected to the mounting base 1 through cooperation with the second pusher 42. The first drive structure 3 has the same structure as the second drive structure 4.

[0036] Reference Figure 1 , Figure 2 , Figure 3 Two second limiting posts 72 are fixed on the mounting base 1. The two second limiting posts 72 are horizontally distributed along the sliding direction of the second push block 41, and the second limiting posts 72 pass through the second through groove 71. A second limiting member 73 is fixed on the second limiting post 72. The second sliding part 411 is limited between the second limiting member 73 and the mounting base 1.

[0037] Reference Figure 1 , Figure 4The slide rail 2 includes a guide block 21 mounted on the mounting base 1. A sliding groove 52 is provided on the plate support 8 to accommodate the guide block 21. The sliding groove 52 engages with the guide block 21, and the plate support 8 slides along the length of the guide block 21. The guide block 21 extends to the end of the mounting base 1 near the loading end, facilitating the installation of the plate support 8. The slide rail 2 also includes a pressure block 22 fixed to the mounting base 1. A receiving groove 53 is provided between the guide block 21 and the pressure block 22. The end of the plate support 8 is slidably connected within the receiving groove 53, and the pressure block 22 slidably contacts the upper surface of the plate support 8, thus restricting the plate support 8 to remain within the receiving groove 53.

[0038] The implementation principle of a high-stability board support or comb pushing mechanism in this application embodiment is as follows: The board support 8 in this application can be replaced by a comb. When in use, the mounting base 1 is installed on the computer longitudinal cutting and trimming machine, and several board supports 8 are placed between the first push plate part 312 and the second push plate part 412. The first drive structure 3 and the second drive structure 4 clamp a row of board supports 8 on the slide rail 2, so that gaps are not likely to occur between the board supports 8, thereby making the cutting wheel stably located in the comb teeth 9 to cut the cardboard, so that the cardboard cutting quality is good and no burrs are produced. When the board support 8 is worn, the first drive structure 3 and the second drive structure 4, after being set by the control system, slide a certain distance toward the unloading end at regular intervals. The sliding distance can be set by the control system as needed. The cutting wheel cuts the cardboard between different comb teeth 9. The first pusher 32 drives the first extension 313 to move the first sliding part 311 closer to the board drop groove 51. At the same time, the second pusher 42 drives the second pusher part 412 to slide synchronously. When the sliding distance is close to that of one board support 8, the control system controls the second drive structure 4 to release the board support 8. After the second drive structure 4 releases the board support 8, a gap of at least one board support 8 is left between the second drive structure 4 and the unloading end of the slide rail 2. The first drive structure 3 pushes one board support 8 away from the slide rail 2, and the worn board support 8 falls into the board drop groove 51. At this time, the first pusher 32 drives the first sliding part 311 to move in the opposite direction, thereby creating a gap of at least one plate holder 8 between the first push plate part 312 and the slide rail 2, so that a new plate holder 8 can be placed into the gap. When the plate holder 8 is put back into the slide rail 2, the second pusher 42 drives the second push plate part 412 to press against the plate holder 8 on the unloading end side, while the first pusher 32 drives the first push plate part 312 to press against the plate holder 8 on the loading end side. Through the first drive structure 3 and the second drive structure 4, a row of plate holders 8 press against each other.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
