Description

Technical Field

[0001] This utility model relates to the technical field of packaging box production equipment, specifically to a folding structure for packaging box production. Background Technology

[0002] In the packaging box manufacturing industry, the folding process is a crucial step that determines the quality and structural stability of the packaging box, directly affecting its appearance, sealing performance, and subsequent user experience. With the diversification of the commodity market, the size and shape of packaging boxes are becoming increasingly diverse, ranging from small jewelry boxes to large appliance packaging boxes. These different specifications place higher demands on the adaptability of production equipment.

[0003] Existing packaging box manufacturing folding structures have highly fixed positioning mechanisms, which can mostly only adapt to packaging boxes of a single size. When processing packaging boxes of different widths and lengths, the position of the positioning components cannot be flexibly adjusted, causing the packaging boxes to easily shift on the placement plate, and resulting in wrinkles and misalignments during folding, seriously affecting the product qualification rate.

[0004] Therefore, a folding structure for packaging box production is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a folding structure for packaging box production in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A folding structure for packaging box production includes a base, a mounting block fixedly connected to the top surface of the base, and a placement plate fixedly connected to the top surface of the mounting block for supporting the packaging box to be folded. The surface of the placement plate is provided with a lateral adjustment component for positioning packaging boxes of different sizes on the placement plate. A positioning rod is fixedly connected to the surface of the lateral adjustment component, a longitudinal adjustment component is provided to the surface of the positioning rod, and a positioning block is fixedly connected to the surface of the longitudinal adjustment component. By cooperating with the lateral and longitudinal adjustment components, the positions of the positioning rod and positioning block can be adjusted according to the size of the packaging box for precise positioning. The surface of the base is provided with a moving component for folding packaging boxes of different sizes. A connecting plate is fixedly connected to the surface of the moving component, a folding component is provided to the surface of the connecting plate, and a folding block is provided to the surface of the folding component. The surface of the placement plate has an adjustment opening. The moving component adjusts the position of the folding component, and the folding component drives the folding block to flip, realizing the folding of packaging boxes of different sizes.

[0008] Furthermore, the lateral adjustment component includes a moving groove, the surface of the placement plate is provided with the moving groove, the inner wall of the moving groove is fixedly connected with a slide rod, the surface of the slide rod is slidably connected with a slider, and the positioning rod is fixedly connected to the slider. The slider slides along the slide rod in the moving groove to realize the lateral position adjustment of the positioning rod.

[0009] Furthermore, the lateral adjustment assembly also includes a threaded sleeve. The surface of the slider is fixedly connected to the threaded sleeve, and the inner wall of the threaded sleeve is threadedly connected to a threaded locking rod. The threaded locking rod is threadedly connected to the slider. The slider is locked by screwing the threaded locking rod into the threaded sleeve, thus fixing the lateral position of the positioning rod.

[0010] Furthermore, the longitudinal adjustment assembly includes an adjustment groove, the surface of the positioning rod is provided with the adjustment groove, a locking rod is movably inserted into the inner wall of the adjustment groove, and the locking rod is locked to the positioning rod by a nut, and the positioning block is fixedly connected to the locking rod. The locking rod moves along the adjustment groove to adjust the longitudinal position of the positioning block, and the nut is locked and fixed.

[0011] Furthermore, the movable component includes a sliding groove, the top surface of the base has a sliding groove, a motor is fixedly connected to the surface of the base, a bidirectional screw is fixedly connected to the output end of the motor, and the bidirectional screw is rotatably connected to the base.

The motor drives the bidirectional screw to rotate, and the movable block moves along the sliding groove on the bidirectional screw, driving the connecting plate to move synchronously and adjusting the position of the folding component.

[0012] Furthermore, the folding assembly includes an electric push rod, which is fixedly connected to the surface of the connecting plate. A toothed plate is fixedly connected to the telescopic rod of the electric push rod. A rotating seat is fixedly connected to the surface of the connecting plate, and the folding block is fixedly connected to the rotating rod of the rotating seat. A gear is fixedly sleeved on the surface of the rotating rod of the rotating seat, and the toothed plate meshes with the gear.

[0027] like Figure 1-5 As shown, a folding structure for packaging box production includes a base 1, a mounting block 2 fixedly connected to the top surface of the base 1, a placement plate 3 fixedly connected to the top surface of the mounting block 2, a lateral adjustment component 4 for positioning and placing packaging boxes of different sizes on the placement plate 3, a positioning rod 5 fixedly connected to the surface of the lateral adjustment component 4, a longitudinal adjustment component 6 fixedly connected to the surface of the positioning rod 5, a positioning block 7 fixedly connected to the surface of the longitudinal adjustment component 6, a moving component 8 for folding packaging boxes of different sizes on the surface of the base 1, a connecting plate 9 fixedly connected to the surface of the moving component 8, a folding component 10 on the surface of the connecting plate 9, a folding block 11 on the surface of the folding component 10, and an adjustment opening 12 on the surface of the placement plate 3. Specifically, in this folding structure for packaging box production, the placement plate 3 is used for placing packaging boxes, and the lateral adjustment component 4 is used for positioning and placing packaging boxes. The adjustment component 4 allows for the horizontal adjustment of the positioning rod 5 and its fixation. The vertical adjustment component 6 allows for the adjustment of the positioning block 7 on the positioning rod 5. Based on the size of the packaging box, the positioning rod 5 and positioning block 7 divide the corresponding area on the placement plate 3 for the installation and positioning of the packaging box on the placement plate 3. The opening of the adjustment port 12 allows the position of the folding block 11 to be adjusted according to different cartons. The moving component 8 moves the connecting plate 9 to a synchronous position that moves closer or further away from each other, thereby adjusting the position of the folding block 11. The folding component 10 causes the folding block 11 to flip, thereby folding the sides of the packaging carton placed on the placement plate 3.

[0028] like Figure 2 , Figure 5As shown, the lateral adjustment component 4 includes a moving groove 401. The surface of the placement plate 3 has a moving groove 401. A slide rod 402 is fixedly connected to the inner wall of the moving groove 401. A slider 403 is slidably connected to the surface of the slide rod 402, and the positioning rod 5 is fixedly connected to the slider 403. Specifically, in the lateral adjustment component 4, the moving groove 401 provides installation and movement space for the slide rod 402 and the slider 403. The slide rod 402 acts as a guide, allowing the slider 403 to slide smoothly along the length of the moving groove 401, thereby driving the positioning rod 5 fixed thereto to move laterally. This adapts to packaging boxes of different widths and adjusts the lateral position of the positioning rod 5 on the placement plate 3, creating conditions for the lateral positioning of the packaging box and ensuring that the position of the packaging box is stable and accurate during subsequent folding.

[0029] like Figure 2 , Figure 5 As shown, the lateral adjustment assembly 4 also includes a threaded sleeve 404. The threaded sleeve 404 is fixedly connected to the surface of the slider 403, and a threaded locking rod 405 is threadedly connected to the inner wall of the threaded sleeve 404. The threaded locking rod 405 is threadedly connected to the slider 403. Specifically, the threaded sleeve 404 and the threaded locking rod 405 in the lateral adjustment assembly 4 cooperate to mainly play a positioning and locking role. When the slider 403 drives the positioning rod 5 to move along the slide bar 402 to a lateral position that matches the size of the packaging box, the threaded locking rod 405 is tightened so that its end abuts against the slide bar 402, locking the positioning rod 5 in the adjusted lateral position.

[0030] like Figure 1 , Figure 5 As shown, the longitudinal adjustment component 6 includes an adjustment groove 601. The surface of the positioning rod 5 has the adjustment groove 601, and a locking rod 602 is movably inserted into the inner wall of the adjustment groove 601. The locking rod 602 is locked to the positioning rod 5 by a nut, and the positioning block 7 is fixedly connected to the locking rod 602. Specifically, the longitudinal adjustment component 6 is designed to adjust and fix the position of the positioning block 7 in the longitudinal direction to accommodate packaging boxes of different lengths. The adjustment groove 601 provides a guide rail for the movement of the locking rod 602, allowing the locking rod 602 to slide along the length of the positioning rod 5, thereby driving the fixedly connected positioning block 7 to move synchronously, thus adjusting the corresponding position of the positioning block 7 in the longitudinal direction relative to the packaging box. Once the positioning block 7 is moved to a position that matches the longitudinal dimensions of the packaging box, the locking rod 602 can be tightly locked onto the positioning rod 5 by tightening the nut on the locking rod 602, thereby fixing the longitudinal position of the positioning block 7. This ensures that the positioning block 7 provides stable and reliable longitudinal positioning of the packaging box during the folding process, preventing the packaging box from shifting due to the displacement of the positioning block 7 and ensuring the quality of the folding.

[0031] like Figure 3 , Figure 4As shown, the moving assembly 8 includes a slide groove 801. The slide groove 801 is formed on the top surface of the base 1. A motor 802 is fixedly connected to the surface of the base 1. A bidirectional screw 803 is fixedly connected to the output end of the motor 802, and the bidirectional screw 803 is rotatably connected to the base 1. A moving block 804 is threadedly connected to the surface of the bidirectional screw 803, and a connecting plate 9 is fixedly connected to the moving block 804. Specifically, in the moving assembly 8, the slide groove 801 provides guidance and limitation for the movement of the moving block 804, ensuring its stable sliding. The motor 802 serves as a power source, driving the bidirectional screw 803 to rotate in both directions. Utilizing its special thread structure, the bidirectional screw 803 can drive two moving blocks 804 to move synchronously closer or further apart along the slide groove 801. The movement of the moving blocks 804 will cause the connecting plate 9 fixed thereto to move synchronously, thereby causing the folding component 10 and folding block 11 on the connecting plate 9 to adjust their positions, so that the folding block 11 can accurately correspond to the folding edge of packaging boxes of different widths, ensuring the accuracy and adaptability of the folding operation.

[0032] like Figure 3 , Figure 4 As shown, the folding assembly 10 includes an electric push rod 1001. The electric push rod 1001 is fixedly connected to the surface of the connecting plate 9. A toothed plate 1002 is fixedly connected to the telescopic rod of the electric push rod 1001. A rotating seat 1003 is fixedly connected to the surface of the connecting plate 9. The folding block 11 is fixedly connected to the rotating rod of the rotating seat 1003. A gear 1004 is fixedly sleeved on the surface of the rotating rod of the rotating seat 1003, and the toothed plate 1002 meshes with the gear 1004. Specifically, in the folding assembly 10, the electric push rod 1001 serves as the power source. The telescopic movement of the telescopic rod can stably drive the toothed plate 1002 to move linearly. The meshing transmission between the toothed plate 1002 and the gear 1004 converts the linear movement of the electric push rod 1001 into the rotational movement of the gear 1004. The gear 1004 is fixedly sleeved on the rotating rod of the rotating seat 1003. This rotational movement is transmitted to the folding block 11 through the rotating rod, so that the folding block 11 can perform a flipping action around the rotating seat 1003. The folding block 11 applies a force to the side of the packaging box positioned on the placement plate 3 by flipping, thus completing the folding operation.

[0033] In summary: Component installation and initial debugging

[0034] Place base 1 stably, and fix mounting block 2 to base 1 and placement plate 3 in sequence. Insert slide rod 402 of horizontal adjustment component 4 into moving groove 401 of placement plate 3, slide block 403 is sleeved on slide rod 402, and positioning rod 5 is fixed to slide block 403; insert locking rod 602 of vertical adjustment component 6 into adjusting groove 601 of positioning rod 5, and connect positioning block 7 to locking rod 602. Install bidirectional screw 803 of moving component 8 into sliding groove 801 of base 1, and connect motor 802, moving block 804, and connecting plate 9 in sequence; install electric push rod 1001 and rotating seat 1003 of folding component 10 on connecting plate 9, assemble gear 1004, toothed plate 1002, and folding block 11 according to meshing and rotational relationships, and check whether the connection and movement of each component are smooth.

[0035] Size adaptation adjustment

[0036] Lateral positioning adjustment: Loosen the threaded locking rod 405, push the positioning rod 5, and slide the slider 403 along the slide rod 402 in the moving groove 401 to adjust to the position that matches the lateral size of the packaging box. Tighten the threaded locking rod 405 and lock the slider 403 through the threaded sleeve 404 to fix the lateral position of the positioning rod 5.

[0037] Longitudinal positioning adjustment: Loosen the nut on the locking rod 602, move the locking rod 602 in the adjustment groove 601, drive the positioning block 7 to adjust the longitudinal position, align with the longitudinal dimension of the packaging box, tighten the nut to fix the locking rod 602 and the positioning rod 5, and complete the longitudinal positioning.

[0038] Folding position adjustment: Start motor 802, bidirectional screw 803 rotates, moving block 804 moves along slide 801, driving connecting plate 9 and folding component 10 to move synchronously, so that folding block 11 corresponds to the position of the packaging box to be folded, and motor 802 stops.

[0039] Folding process

[0040] Loading and positioning: Place the packaging box on the placement plate 3, and use the positioning rod 5 and positioning block 7, which are adjusted to hold the packaging box in place, to ensure accurate positioning.

[0041] Folding operation: Activate the electric push rod 1001 of the folding assembly 10. The telescopic rod extends and pushes the toothed plate 1002 to move. The toothed plate 1002 meshes with the gear 1004, causing the rotating rod of the rotating seat 1003 to rotate. The folding block 11 flips accordingly, folding the side of the packaging box. After the folding is completed, the telescopic rod of the electric push rod 1001 retracts, driving the toothed plate 1002 to move back, and the folding block 11 returns to its original position.

[0042] Material feeding and recycling: Take out the folded packaging box. If you need to continue working, repeat the feeding, positioning, and folding steps to achieve continuous production.
