Description

Technical Field

[0001] This application relates to the field of cardboard box processing equipment technology, and in particular to an automatic cardboard box pressing device. Background Technology

[0002] Cardboard boxes are rigid or semi-rigid packaging containers made primarily of paper materials, mainly used for the transportation, storage, and sales of goods.

[0003] In the production process of cardboard boxes, in order to improve the sturdiness of the boxes, multiple layers of structural paper are stacked in a specific order. Adhesive is then used to bond adjacent layers of structural paper together. After the adhesive is applied, the multiple layers of structural paper are pressed together to form a whole, thereby improving the sturdiness of the cardboard box.

[0004] Chinese Patent No. CN211195123U discloses a pressing plate device for carton production, including a mounting plate, a mounting groove, a conveyor belt, a bracket, a hydraulic cylinder, and a pressing plate. The mounting groove is opened on the top of the mounting plate, the conveyor belt is disposed in the mounting groove, and the top of the conveyor belt is horizontal with the mounting plate. The bracket is fixedly installed on the top of the mounting plate, the hydraulic cylinder is fixedly installed on the bracket, and the pressing plate is fixedly installed on the output shaft of the hydraulic cylinder.

[0005] In the process of using the above technology, the hydraulic cylinder can only press down one piece of cardboard at a time, and each piece of cardboard requires a certain amount of time to press down, which leads to low cardboard production efficiency and has shortcomings. Utility Model Content

[0006] To address the issue of low efficiency in cardboard production, this application provides an automatic cardboard box pressing device.

[0007] The automatic carton pressing device provided in this application adopts the following technical solution:

[0008] An automatic cardboard pressing device includes a processing frame and a feeding assembly. The processing frame has a guide post vertically arranged on it, and a plurality of extrusion plates are slidably sleeved on the guide post along its axial direction. A pull rope is arranged between each pair of adjacent extrusion plates. The lowermost extrusion plate is disposed on the processing frame. The processing frame is provided with an extrusion component that drives the uppermost extrusion plate to slide. The feeding assembly is used to feed cardboard between two adjacent extrusion plates.

[0009] By adopting the above technical solution, the extruder drives the uppermost extrusion plate to slide upwards, and the two adjacent extrusion plates gradually separate from each other through the pull ropes until all the pull ropes are in a taut state. Then, the feeding component conveys the cardboard between the two adjacent extrusion plates. Finally, the extruder drives the uppermost extrusion plate to slide downwards, so that the cardboard between the two adjacent extrusion plates is squeezed, thereby shortening the time spent squeezing multiple cardboards and improving the production efficiency of cardboard.

[0010] Optionally, the extrusion component includes a pressure plate cylinder disposed on the top of the processing frame. The pressure plate cylinder is electrically connected to the control system. An end plate is disposed on the piston rod of the pressure plate cylinder, and the uppermost extrusion plate is disposed on the end plate.

[0011] By adopting the above technical solution, the control system starts the pressure plate cylinder, the piston rod of the pressure plate cylinder extends, and the piston rod of the pressure plate cylinder drives the uppermost extrusion plate to slide synchronously through the end plate.

[0012] Optionally, the feeding assembly includes a feeding frame disposed next to the processing frame, a lifting frame slidably disposed vertically on the feeding frame, a lifting component disposed on the feeding frame for driving the lifting frame to slide vertically, a plurality of feeding rollers rotatably disposed on the lifting frame, the plurality of feeding rollers being arranged along the direction from the feeding frame to the processing frame, a conveyor belt being wound around the plurality of feeding rollers, a feeding motor electrically connected to the control system disposed on the lifting frame, one of the feeding rollers located at the end in the direction of the feeding roller arrangement being coaxially disposed on the output shaft of the feeding motor, and a plate-laying component disposed on the lifting frame for sequentially placing cardboard.

[0013] By adopting the above technical solution, the lifting component drives the lifting frame to slide vertically, so that the upper surface of the conveyor belt is parallel to the upper surface of one of the extrusion plates. Then, the plate-laying component places a cardboard on the conveyor belt. Then, the control system starts the feeding motor. The output shaft of the feeding motor drives the conveyor belt to rotate through the feeding roller. The rotating conveyor belt transports the cardboard to the upper surface of the extrusion plate. Then, the lifting component drives the lifting frame to slide vertically again. The operation is repeated until a cardboard is placed on each extrusion plate.

[0014] Optionally, the lifting component includes a winding wheel rotatably mounted on the top of the loading rack, with a pull wire wound on the winding wheel. One end of the pull wire facing away from the winding wheel is mounted on the lifting frame. A vision camera electrically connected to the control system is mounted on the lifting frame. The vision camera is used to capture images of the extrusion plate. An avoidance slot is provided on the top of the loading rack for the pull wire to pass through. A lifting motor electrically connected to the control system is mounted on the top of the loading rack. The winding wheel is coaxially mounted on the output shaft of the lifting motor.

[0015] By adopting the above technical solution, the control system starts the lifting motor, the output shaft of the lifting motor drives the winding wheel to rotate in the forward direction, the winding wheel rotates to wind up the wire, the wire pulls the lifting frame up, at this time the visual camera constantly feeds back the position of the extrusion plate until the design position is reached, the control system stops the lifting motor.

[0016] Optionally, the board placement component includes a board placement box disposed on the lifting frame. The top and bottom of the board placement box are connected. The cardboard is vertically stacked inside the board placement box. The open bottom end of the board placement box is located directly above the conveyor belt. A board placement slot is provided between the inner and outer walls of the bottom end of the board placement box near the processing frame. The vertical width of the board placement slot is greater than the thickness of one cardboard but less than the thickness of two cardboards.

[0017] By adopting the above technical solution, when the conveyor belt rotates, a piece of cardboard attached to the conveyor belt slides out from the plate release slot under the action of the conveyor belt friction. The width of the plate release slot will limit that only one piece of cardboard can be released at a time, thereby controlling the effect that only one piece of cardboard can be released at a time on each extrusion plate.

[0018] Optionally, a pusher plate is provided between the plate placement slot and the extrusion plate of the plate placement box. A baffle is rotatably provided on the side of the pusher plate facing away from the plate placement box. The end of the baffle away from its rotation center is close to the conveyor belt. A paper pushing cylinder electrically connected to the control system is provided on the plate placement box. The pusher plate is provided on the piston rod of the paper pushing cylinder.

[0019] By adopting the above technical solution, when the conveyor belt slides onto the extrusion plate, the cardboard will first be pushed by the baffle and rotate until the cardboard separates from the baffle. At this time, the baffle rotates and falls back under the action of gravity. As the conveyor belt continues to rotate until the cardboard separates from the conveyor belt, the end of the cardboard is not completely within the extrusion range of the extrusion plate. Then the control system starts the paper pushing cylinder. The piston rod of the paper pushing cylinder extends. Since the pushing plate will prevent the baffle from rotating toward the board box at this time, the baffle will push the cardboard to continue sliding a distance on the extrusion plate, thereby completing the cardboard feeding process.

[0020] Optionally, the baffle is made of a lightweight material.

[0021] By adopting the above technical solution, the cardboard can be used to drive the baffle to rotate.

[0022] Optionally, a door panel is rotatably mounted on the tray box, and a latch is provided between the door panel and the tray box.

[0023] By adopting the above technical solution, workers can quickly open the door panel using the buckle, which makes it convenient for workers to replenish cardboard into the cardboard box.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. The extrusion drive moves the top extrusion plate upwards, and the two adjacent extrusion plates gradually separate from each other through the pull ropes until all the pull ropes are taut. Then the feeding assembly feeds the cardboard between the two adjacent extrusion plates. Finally, the extrusion drive moves the top extrusion plate downwards, so that the cardboard between the two adjacent extrusion plates is squeezed. This shortens the time spent squeezing multiple cardboards and improves the production efficiency of cardboard.

[0026] 2. The lifting mechanism drives the lifting frame to slide vertically, so that the upper surface of the conveyor belt is parallel to the upper surface of one of the extrusion plates. Then, the plate-laying component places a cardboard on the conveyor belt. The control system then starts the feeding motor. The output shaft of the feeding motor drives the conveyor belt to rotate through the feeding roller. The rotating conveyor belt transports the cardboard to the upper surface of the extrusion plate. Then, the lifting mechanism drives the lifting frame to slide vertically again. The operation is repeated until a cardboard is placed on each extrusion plate.

[0027] 3. As the conveyor belt slides onto the extrusion plate, the cardboard is first pushed by the baffle and rotates until the cardboard separates from the baffle. At this point, the baffle rotates and falls back under the action of gravity. As the conveyor belt continues to rotate until the cardboard separates from the conveyor belt, the end of the cardboard is not completely within the extrusion range of the extrusion plate. Then, the control system activates the paper-pushing cylinder, and the piston rod of the paper-pushing cylinder extends. Since the pushing plate will prevent the baffle from rotating toward the board box at this time, the baffle will push the cardboard to continue sliding a distance on the extrusion plate, thus completing the cardboard feeding process.

[0033] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0034] This application discloses an automatic carton pressing device.

[0035] Reference Figure 1 An automatic carton pressing device includes a processing frame 2 and a feeding assembly 3. A base plate 13 is welded to the bottom of the processing frame 2. A guide post 4 is vertically welded to the base plate 13. Multiple extrusion plates 5 are vertically slidably mounted on the guide post 4 along its axis. A pull rope 6 is tied between each adjacent extrusion plate 5. The pull rope 6 can be a steel wire rope in the prior art. The extrusion plate 5 located at the bottom is bolted to the base plate 13 at the bottom of the processing frame 2.

[0036] Reference Figure 1 and Figure 2 The processing frame 2 is equipped with an extrusion component 7 that drives the uppermost extrusion plate 5 to slide. The extrusion component 7 includes a pressure plate cylinder 71 bolted to the top of the processing frame 2. The pressure plate cylinder 71 is electrically connected to the control system. An end plate 72 is welded to the piston rod of the pressure plate cylinder 71, and the uppermost extrusion plate 5 is bolted to the end plate 72.

[0037] The control system starts the pressure plate cylinder 71, the piston rod of the pressure plate cylinder 71 retracts, and the piston rod of the pressure plate cylinder 71 drives the uppermost extrusion plate 5 to slide vertically upward through the end plate 72. At the same time, the extrusion plate 5 in the middle gradually slides vertically upward in sequence under the action of the pull rope 6 until the pull rope 6 is tightened. At this time, the pressure plate cylinder 71 stops working.

[0038] Reference Figure 1 and Figure 2 The feeding assembly 3 is used to feed the cardboard 1 between two adjacent extrusion plates 5. The feeding assembly 3 includes a feeding rack 31 arranged next to the processing rack 2. A lifting frame 32 is vertically slidably arranged on the feeding rack 31. A lifting component 33 is arranged on the feeding rack 31 to drive the lifting frame 32 to slide vertically.

[0039] Reference Figure 1 and Figure 3 The lifting component 33 includes a winding wheel 331 rotatably connected to the top of the feeding frame 31. A pull wire 332 is wound on the winding wheel 331. The pull wire 332 can be a steel wire rope in the prior art. One end of the pull wire 332 facing away from the winding wheel 331 is tied to the lifting frame 32. A vision camera 333 electrically connected to the control system is attached to the lifting frame 32. The vision camera 333 is used to photograph the extrusion plate 5.

[0040] Reference Figure 1 The top of the feeding rack 31 is provided with a clearance slot 334 for the pull wire 332 to pass through. The top of the feeding rack 31 is bolted with a lifting motor 335 that is electrically connected to the control system. The lifting motor 335 can be a double-headed motor as in the prior art. The winding wheel 331 is coaxially connected to the output shafts at both ends of the lifting motor 335.

[0041] Reference Figure 2 Multiple conveying rollers 34 are rotatably connected to the lifting frame 32. The multiple conveying rollers 34 are arranged along the direction from the loading frame 31 to the processing frame 2. A conveyor belt 35 is wound around the multiple conveying rollers 34. A conveying motor 36 electrically connected to the control system is bolted to the lifting frame 32. One of the conveying rollers 34 located at the end in the arrangement direction of the conveying rollers 34 is coaxially bolted to the output shaft of the conveying motor 36.

[0042] Reference Figure 3 and Figure 4 The lifting frame 32 is provided with a board placement component 37 for placing cardboard 1 in sequence. The board placement component 37 includes a board box 371 bolted to the lifting frame 32. The top and bottom of the board box 371 are connected. The cardboard 1 is vertically stacked in the board box 371. A door panel 11 is rotatably connected to the board box 371. A buckle 12 is arranged between the door panel 11 and the board box 371.

[0043] Reference Figure 2 , Figure 3 and Figure 4 The bottom open end of the plate holder 371 is located directly above the conveyor belt 35. A plate placement slot 372 is provided between the inner and outer walls of the bottom end of the plate holder 371 near the processing frame 2. The vertical width of the plate placement slot 372 is greater than the thickness of one piece of cardboard 1 but less than the thickness of two pieces of cardboard 1.

[0044] Reference Figure 2 , Figure 3 and Figure 4A pusher plate 8 is arranged between the plate placement slot 372 of the plate placement box 371 and the extrusion plate 5. The pusher plate 8 is located above the conveyor belt 35. A baffle 9 is rotatably connected to the side of the pusher plate 8 facing away from the plate placement box 371. The baffle 9 is made of lightweight material. The end of the baffle 9 away from its rotation center is close to the conveyor belt 35. A paper pushing cylinder 10 electrically connected to the control system is bolted to the plate placement box 371. The pusher plate 8 is bolted to the piston rod of the paper pushing cylinder 10.

[0045] The control system starts the lifting motor 335. The output shaft of the lifting motor 335 drives the winding wheel 331 to rotate in the forward direction. The winding wheel 331 rotates to wind up the pull wire 332. The pull wire 332 pulls the lifting frame 32 up. At the same time, the vision camera 333 continuously feeds back the position of the extrusion plate 5 until it reaches the design position. At this time, the control system stops the lifting motor 335.

[0046] Then the control system starts the feeding motor 36. The output shaft of the feeding motor 36 drives the conveyor belt 35 to rotate through the feeding roller 34. The rotating conveyor belt 35 drives the cardboard 1 to slide through friction. Due to the size limitation of the board slot 372, the conveyor belt 35 can only convey one cardboard 1 at a time.

[0047] After the cardboard 1 slides out of the plate slot 372, it will push the baffle 9 to rotate until the cardboard 1 slides onto the extrusion plate 5. At this time, as the conveyor belt 35 continues to transport the cardboard 1, the cardboard 1 will gradually separate from the baffle 9. At this time, the baffle 9 will rotate and remain vertically arranged.

[0048] The conveyor belt 35 continues to transport the cardboard 1 until the cardboard 1 separates from the conveyor belt 35. Then the control system starts the paper-pushing cylinder 10. The piston rod of the paper-pushing cylinder 10 extends. Since the pusher plate 8 will prevent the baffle 9 from rotating toward the plate box 371 at this time, the baffle 9 will push the cardboard 1 to a suitable position on the extrusion plate 5, thereby completing the feeding process of a single cardboard 1.

[0049] Then repeat the operation until each extrusion plate 5 is filled with cardboard 1. Finally, the control system starts the pressure plate cylinder 71. The piston rod of the pressure plate cylinder 71 extends and drives the uppermost extrusion plate 5 to descend through the end plate 72, thereby squeezing multiple cardboard pieces 1.

[0050] The implementation principle of the automatic carton pressing device in this application embodiment is as follows: the control system starts the pressing cylinder 71, the piston rod of the pressing cylinder 71 retracts, and the piston rod of the pressing cylinder 71 drives the uppermost pressing plate 5 to slide vertically upward through the end plate 72. At the same time, the pressing plate 5 in the middle gradually slides vertically upward in sequence under the action of the pull rope 6 until the pull rope 6 is tightened. At this time, the pressing cylinder 71 stops working.

[0051] The control system starts the lifting motor 335. The output shaft of the lifting motor 335 drives the winding wheel 331 to rotate in the forward direction. The winding wheel 331 rotates to wind up the pull wire 332. The pull wire 332 pulls the lifting frame 32 up. At the same time, the vision camera 333 continuously feeds back the position of the extrusion plate 5 until it reaches the design position. At this time, the control system stops the lifting motor 335.

[0052] Then the control system starts the feeding motor 36. The output shaft of the feeding motor 36 drives the conveyor belt 35 to rotate through the feeding roller 34. The rotating conveyor belt 35 drives the cardboard 1 to slide through friction. Due to the size limitation of the board slot 372, the conveyor belt 35 can only convey one cardboard 1 at a time.

[0053] After the cardboard 1 slides out of the plate slot 372, it will push the baffle 9 to rotate until the cardboard 1 slides onto the extrusion plate 5. At this time, as the conveyor belt 35 continues to transport the cardboard 1, the cardboard 1 will gradually separate from the baffle 9. At this time, the baffle 9 will rotate and remain vertically arranged.

[0054] The conveyor belt 35 continues to transport the cardboard 1 until the cardboard 1 separates from the conveyor belt 35. Then the control system starts the paper-pushing cylinder 10. The piston rod of the paper-pushing cylinder 10 extends. Since the pusher plate 8 will prevent the baffle 9 from rotating toward the plate box 371 at this time, the baffle 9 will push the cardboard 1 to a suitable position on the extrusion plate 5, thereby completing the feeding process of a single cardboard 1.

[0055] Then repeat the operation until each extrusion plate 5 is filled with cardboard 1. Finally, the control system starts the pressure plate cylinder 71. The piston rod of the pressure plate cylinder 71 extends and drives the uppermost extrusion plate 5 to descend through the end plate 72, thereby squeezing multiple cardboard pieces 1.

[0056] 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.
