Technical Field
[0001] This application relates to the field of cardboard conveying technology, and in particular to a cardboard conveying limiting mechanism. Background Technology
[0002] A cardboard conveyor limiting mechanism is a device installed on a cardboard conveyor line. Its main function is to limit the movement range of the cardboard during the conveying process, ensuring that the cardboard is conveyed according to a predetermined path and position. Through the action of the limiting mechanism, displacement of the cardboard caused by vibration, wind, or other external factors during conveying can be avoided, thereby improving the accuracy and efficiency of cardboard processing.
[0003] Limiting mechanisms typically use nuts and threaded knobs to adjust the height according to the cardboard size. However, machine vibrations may cause the screws to loosen, affecting the limiting effect. Over time, the screws may also rust and strip, making adjustment impossible. Utility Model Content
[0004] In order to improve the problem of loosening and stripping of the adjusting screw due to vibration, which affects the limiting effect, this application provides a cardboard conveying limiting mechanism.
[0005] The paperboard conveying and limiting mechanism provided in this application adopts the following technical solution:
[0006] A cardboard conveying limiting mechanism includes a conveying plate and a conveyor belt. A fixed rod is provided on one side of the conveyor belt. A T-shaped slide bar for adjusting the position of the entire device is slidably provided on one side of the fixed rod. A horizontal plate for supporting rollers is rotatably provided on one side of the T-shaped slide bar. One side of the horizontal plate is connected to a fixed block through a threaded knob, thereby limiting the cardboard that the rollers are sliding over.
[0007] An adjustment mechanism is provided on one side of the T-shaped slide bar. The adjustment mechanism includes a base plate fixed to one side of the T-shaped slide bar. A lead screw is rotatably provided on one side of the base plate to drive several threaded moving blocks to reciprocate synchronously. Each of the moving blocks has a guide post at both ends that is fixed to a trapezoidal connecting rod that pushes the horizontal plate up and down. A gripping knob is fixed on the side of the lead screw away from the moving blocks. A knob cover is provided on one side of the gripping knob. A limit buckle is provided on one side of the knob cover to limit the movement of the lead screw. A fixing plate is fixed on one side of the fixing rod to fix the adjustment mechanism.
[0008] By adopting the above technical solution, the height of the rollers rotating on the horizontal plate can be adjusted through the cooperation of the adjustment mechanism and the horizontal plate. This allows for better limiting of the cardboard during the cardboard conveying process, reduces loosening caused by machine vibration, and minimizes factors that affect the limiting effect.
[0009] Preferably, the adjustment mechanism further includes an L-shaped back plate fixed to one side of the fixed plate, and one side of the L-shaped back plate is provided with an internal thread that is threaded to the external thread of the twist cover.
[0010] By adopting the above technical solution, the internal and external threads can help the L-shaped back plate and the twist cap to be connected more easily.
[0011] Preferably, the inside of one side of the twisted cap is provided with an inclined groove for insertion with the limiting buckle.
[0012] By adopting the above technical solution, by twisting the cover, the cover with the inclined groove abuts against the limit buckle, thereby enabling the inclined groove and the limit buckle to cooperate to fix the screw.
[0013] Preferably, one side of each of the trapezoidal connecting rods is fixed with a rotating shaft that is connected to a plurality of internal grooves opened on one side of the fixing block.
[0014] By adopting the above technical solution, the trapezoidal connecting rod can drive the fixed block to rise and fall without the inability to achieve the rising and falling due to the angle between the trapezoidal connecting rod and the fixed block.
[0015] Preferably, a plurality of mutually symmetrical transverse sliding grooves are provided on one side of the fixing plate, and the transverse sliding grooves are slidably connected to the trapezoidal connecting rod.
[0016] By adopting the above technical solution, the transverse groove can limit the trapezoidal connecting rod while also serving as a guide.
[0017] Preferably, a fixing plate that is fixedly connected to the fixing rod is fixed on one side of the fixing plate.
[0018] By adopting the above technical solution, the fixing plate can help fix the entire device to the fixing rod.
[0019] Preferably, a second rotating shaft that is rotatably connected to the cross plate is rotatably provided at the middle of one side of the T-shaped slide bar.
[0020] By adopting the above technical solution, the second pivot can help support the T-shaped slide bar when it is connected to the horizontal plate and allow the horizontal plate to rotate freely.
[0021] Preferably, both ends of the guide posts are fixedly connected to one side of the movable blocks and movably connected to the other side.
[0022] By adopting the above technical solution, the guide posts and the moving blocks on both sides are fixed and connected through each other, so that the moving blocks can move the guide posts while limiting the guide posts.
[0023] In summary, this application includes at least one of the following beneficial technical effects:
[0024] 1. By using the screw and the moving block in cooperation, the guide column and the trapezoidal connecting rod can adjust the height of the horizontal plate and the fixed block, thereby adjusting the height of the roller to limit the cardboard.
[0025] 2. By using the twist cap and the L-shaped back plate to cooperate, the inclined groove and the limit buckle abut against each other and squeeze each other, so that the limit buckle and the lead screw are in contact and rub against each other to limit the movement.

[0034] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.
[0035] This application discloses a cardboard conveying limiting mechanism.
[0036] Reference Figures 1-3A cardboard conveying limiting mechanism includes a conveyor plate 1 that supports the cardboard during conveying and a conveyor belt 2 arranged in an array at intervals on the conveyor plate 1. The conveyor belt 2 needs to be adjusted according to the width of the cardboard to facilitate normal transport of the cardboard. A fixed rod 3 is provided on one side of the upper end of the conveyor belt 2 to support and slide the entire adjustment mechanism 5. There is a certain distance between the fixed rod 3 and the conveyor belt 2 to facilitate the cardboard to pass through the middle. A smooth T-shaped groove is provided on one side of the fixed rod 3, so that the T-shaped slide bar 4, which also has a smooth surface, can slide and limit each other with the T-shaped slide bar. Thus, the T-shaped slide bar 4 can support the entire device and adjust the position of the entire device on the fixed rod 3.
[0037] Reference Figures 2-5 An adjustment mechanism 5 is provided on one side of the T-shaped slide bar 4. The adjustment mechanism 5 includes a base plate 51 fixedly installed at the lower end of the surface of the T-shaped slide bar 4 away from the fixed rod 3. A lead screw 52 is rotatably installed in the middle of one side of the base plate 51. The threads at both ends of the lead screw 52 are opposite, so that several moving blocks 53 connected by external threads can move relative to each other. That is, two moving blocks 53 can move closer or further away from each other when the lead screw 52 rotates. The end of the lead screw 52 away from the base plate 51 moves through the fixed plate 9 and is located in the middle between two transverse slide grooves 14. A gripping knob 54 is fixedly installed at the end of the lead screw 52 away from the base plate 51. Rotating the gripping knob 54 can drive the lead screw 52 to rotate in the middle of the base plate 51, thereby driving the mutually symmetrical and identical moving blocks 53 to perform synchronous reciprocating motion.
[0038] Reference Figures 2-5 Each of the several movable blocks 53 has a guide post 55 with the same structure and a smooth surface at both ends. One of the guide posts 55 on both sides of the movable block 53 is fixedly connected to one side of the upper movable block 53 and movably connected to the lower movable block 53. Conversely, the other guide post 55 is movably connected to the upper movable block 53 and fixedly connected to the lower movable block 53. Thus, when the movable blocks 53 at both ends move closer to each other, the guide posts 55 on both sides can guide and limit the movement of the movable blocks 53, but will not restrict the movement of the movable blocks 53. The farthest distance that the two movable blocks 53 can move is the length of the guide post 55.
[0039] Reference Figures 2-5A trapezoidal connecting rod 56 is fixedly installed through the middle of the guide post 55, and a rotating shaft 57 is fixedly installed through the end of the trapezoidal connecting rod 56 away from the guide post 55. The rotating shaft 57 is rotatably connected to the inner groove 11 opened on the surface opposite to the fixed block 10. As the moving block 53 pushes the guide post 55 to rise and fall, the trapezoidal connecting rods 56 on both sides can rotate the fixed block 10 to adjust the height of both ends. At the same time, the height of both ends of the horizontal plate 6 fixed to the fixed block 10 is adjusted, so that the roller 7 on one side of the horizontal plate 6 can accurately contact the cardboard and limit the cardboard.
[0040] Reference Figures 2-5 A toggle cover 510 is movably installed through the grip knob 54 on one side of the moving block 53. An external thread 511 is formed on the outside of the toggle cover 510, and an internal thread 512 is connected to the external thread 511. The internal thread 512 is located in the middle of the surface of the L-shaped back plate 58 on one side of the grip knob 54. The other side of the L-shaped back plate 58 is fixedly connected to the fixing plate 9, thus allowing the L-shaped back plate 58 to support and limit the toggle cover 510. A sloping groove 513 is formed in the inner cavity of the toggle cover 510 on the side away from the grip knob 54. The sloping groove 513 is designed with a larger lower diameter and a smaller upper diameter. The upper diameter is larger than that of the inclined groove 513. A limit buckle 59 is inserted and installed on the side of the inclined groove 513 away from the grip knob 54. The diameter of the opening of the limit buckle 59 is the same as the maximum diameter of the inclined groove 513. When the limit buckle 59 is closed, its diameter is the same as the minimum diameter of the inclined groove 513. This allows the inclined groove 513 to abut against the limit buckle 59 when it moves down with the twist cover 510, thereby squeezing the limit buckle 59 and closing it. This allows the inner wall of the limit buckle 59 to abut against and rub against the upper side wall of the lead screw 52, thus preventing the lead screw 52 from rotating due to vibration or other non-human causes, which would affect the limiting of the paperboard by the roller 7.
[0041] The fixed rod 3 supports the entire limiting device and adjusts its position by cooperating with the T-shaped slide rod 4. By twisting the grip knob 54, the grip knob 54 rotates the lead screw 52 on the base plate 51 and the fixed plate 9, which in turn causes the lead screw 52 to move the moving block 53 towards the center. This causes the guide column 55 to move the trapezoidal connecting rod 56 in opposite directions, thereby lifting and pressing down both ends of the fixed block 10 through the trapezoidal connecting rod 56. This results in the horizontal plate 6, which is fixed to the fixed block 10, being higher at one end and lower at the other, thus achieving the purpose of height adjustment according to the size of the cardboard.
[0042] At this time, by twisting the cap 510, the external thread 511 and the internal thread 512 are spirally connected, which in turn makes the inclined groove 513 contact the limit buckle 59. This causes the inclined groove 513 to slowly push the limit buckle 59 inward until the limit buckle 59 is completely closed and fully fits the lead screw 52, thereby achieving a frictional reinforcement effect on the lead screw 52. Furthermore, the surfaces of the lead screw 52 and the limit buckle 59 can be set to a frosted surface or a striped surface, which can increase the friction and improve the fixing effect.
[0043] Reference Figures 1-5 A rotating shaft 12 is rotatably installed in the middle of the side of the T-shaped slide bar 4 away from the fixed rod 3, and the T-shaped slide bar 4 is rotatably connected to the horizontal plate 6 through the rotating shaft 12. A roller 7 is rotatably installed at the end of the side of the horizontal plate 6 away from the T-shaped slide bar 4, and the roller 7 is used to limit the sliding cardboard. A threaded knob 8 is threaded through the side of the horizontal plate 6 away from the roller 7, and the horizontal plate 6 is fixedly connected to one of the fixed blocks 10 through the threaded knob 8. The movable shaft in the middle of the roller 7 passes through the horizontal plate 6 and is connected to the other fixed block 10, so that the fixed blocks 10 on both sides of the horizontal plate 6 are connected to the horizontal plate 6 and can rotate with the horizontal plate 6.
[0044] Reference Figures 1-5 A fixing plate 9 is abutting against the upper end of one side of the fixing rod 3, and a fixing piece 13 is fixed to the lower end of the fixing plate 9 by screws. The fixing piece 13 can be inserted into the upper end of the T-shaped slide groove opening in the middle of the fixing rod 3 for locking, and is fixed to the fixing rod 3 by screws fixed to the fixing plate 9. Thus, the fixing plate 9 can fix the adjustment mechanism 5 set on the side away from the fixing piece 13. Several transverse slide grooves 14 are opened on the side of the fixing plate 9 away from the fixing piece 13. It is best to set two transverse slide grooves 14 that are symmetrical to each other. The width of the two transverse slide grooves 14 is the same and is greater than the width of the trapezoidal connecting rod 56, so that the trapezoidal connecting rod 56 can slide through the transverse slide grooves 14.
[0045] Tightening the threaded knob 8 can fix the fixed block 10 to one end of the horizontal plate 6, and the movable shaft of the roller 7 passes through the horizontal plate 6 and connects to the fixed block 10, so that the horizontal plate 6 and the fixed block 10 can form a whole. This makes it convenient for the adjustment mechanism 5 to adjust the height of the fixed block 10, and the horizontal plate 6 and the roller 7 can be adjusted synchronously. The fixed plate 9 can be fixed to the fixed rod 3 through the fixed piece 13. The fixed plate 9 is connected to the lead screw 52 and the L-shaped back plate 58, which indirectly supports the adjustment mechanism 5. The transverse sliding groove 14 opened on one side of the fixed plate 9 and the trapezoidal connecting rod 56 can also play an auxiliary role and limit and guide the trapezoidal connecting rod 56.
[0046] The implementation principle of the cardboard conveying limiting mechanism in this application embodiment is as follows: When it is necessary to adjust the position of the device on the fixed rod 3, the fixing screw on one side of the fixed plate 9 can be loosened so that the entire device can move on the fixed rod 3 until it moves to the designated position. Then, the screw is tightened for reinforcement. Then, the screw rod 52 is rotated by twisting the grip knob 54, which drives the two moving blocks 53 to move towards the middle. This causes the guide column 55 to move in opposite directions with the trapezoidal connecting rod 56. The trapezoidal connecting rod 56 lifts and presses down both ends of the fixed block 10, so that the fixed block 10 and the horizontal plate 6, as well as the roller 7 and the threaded knob 8, achieve the same phenomenon of one end being higher and the other lower, thereby enabling the roller 7 to adjust its height according to the cardboard size.
[0047] When the height adjustment is complete, the external thread 511 and the internal thread 512 are connected by twisting the cap 510, which in turn connects the inclined groove 513 with the limit buckle 59, thereby causing the limit buckle 59 to move towards the lead screw 52 and close until it is completely in contact with the lead screw 52, thus strengthening the lead screw 52.
[0048] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
