Description

Technical Field

[0001] This utility model belongs to the field of gift box production technology, and more specifically, it relates to an auxiliary positioning device for high-precision gift box lamination production. Background Technology

[0002] By laminating the surface of paper gift boxes, the aesthetics and waterproof performance of the gift boxes can be greatly enhanced. Laminating machines are commonly used gift box laminating equipment. They generally consist of an equipment frame, a film unwinding section, a conveyor belt for transporting gift boxes, an adhesive coating system, and a hot pressing system. The conveyor belt has a mechanical auxiliary positioning mechanism for fixing the gift boxes, which generally consists of baffles on both sides and pressing rollers to prevent the paper boxes from undulating.

[0003] Existing application number: CN202022842553.5, this utility model discloses a cardboard box bottom sealing laminating machine, relating to the field of laminating machines. It includes a worktable, with a motor mounted on the outer surface of the worktable, and a drive wheel mounted on the output end of the motor via a rotating shaft. This utility model, by configuring a fixed plate, a first sliding groove, a pressing plate, a movable rod, and a first spring, allows the user to accurately control the downward movement of the pressing plate when applying adhesive film to the cardboard box. This allows the user to press the movable rod downwards, causing it to push the pressing plate downwards within the first sliding groove. The pressing plate then pulls the first spring downwards, allowing for precise control of the downward movement distance of the pressing plate. This ensures that the adhesive film is compressed during lamination, resulting in a smooth and even application to the cardboard box, effectively laminating the box and improving its performance. Subsequently, after lamination is completed, the first spring, having been compressed, returns to its original position, causing the pressing plate and movable rod to move upwards.

[0004] Based on the above, when the width of the cardboard box changes, the baffles used to guide and limit its transmission angle need to be adjusted accordingly. The traditional adjustment method requires adjusting the front and rear baffles inward or outward one by one. During the operation, not only do they need to be operated one by one, but it is also difficult to ensure that the adjustment length of the baffles on both sides is consistent, which makes it difficult for the cardboard box to be accurately positioned in the middle of the conveyor belt. The pressing rollers used to suppress the undulations of the cardboard box also need to be added or removed according to the width of the cardboard box. The whole adjustment process is cumbersome. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an auxiliary positioning device for high-precision gift box lamination production. This device solves the problem that when the width of a paper box changes, the baffles used for guiding and limiting its transmission angle need to be adjusted accordingly. Traditional adjustment methods require adjusting the front and rear baffles inward or outward one by one. This not only requires individual operation but also makes it difficult to ensure that the adjustment lengths of the baffles on both sides are consistent, resulting in the paper box being difficult to accurately position in the middle of the conveyor belt. Furthermore, the pressing rollers used to suppress the undulations of the paper box also require adding or removing excess rollers according to the width of the paper box, making the entire adjustment process cumbersome.

[0006] The purpose and effect of this utility model, an auxiliary positioning device for high-precision gift box lamination production, are achieved by the following specific technical means:

[0007] A high-precision auxiliary positioning device for gift box lamination production includes a laminating machine body, a conveyor belt, a fixed plate, a transmission box, a first operating handwheel, a transmission worm gear, a support frame, a guide adjustment assembly, and a spacing adjustment assembly. The conveyor belt is disposed inside the laminating machine body. The fixed plate is fixedly connected inside the laminating machine body.

Two transmission worm gears are provided; the right transmission worm gear is coaxially fixedly connected to the left side of the first operating handwheel, and the left transmission worm gear is coaxially fixedly connected to the left end of the right transmission worm gear. Three support frames are provided, and the three support frames are dispersedly fixedly connected to the fixed plate. Two sets of guide adjustment assemblies are provided, each set positioned behind the two transmission worm gears. Three sets of spacing adjustment assemblies are provided, each set positioned inside one of the three support frames.

[0008] Furthermore, the guiding adjustment assembly includes: a transmission worm gear, a connecting shaft, and a first transmission screw; the transmission worm gear is rotatably connected inside the transmission box and meshes with the transmission worm; the connecting shaft is rotatably connected inside the fixed plate; two first transmission screws are provided, with opposite threads on the surfaces of the two first transmission screws, the front first transmission screw having its front and rear ends coaxially fixedly connected to the transmission worm and the inner end of the connecting shaft respectively, and the rear first transmission screw being coaxially fixedly connected to the rear end of the connecting shaft.

[0009] Furthermore, the guide adjustment assembly also includes: a transmission slider and a baffle; two transmission sliders are provided, and the two transmission sliders are slidably connected inside the fixed plate, and the two transmission sliders are respectively threadedly connected to two first transmission screws; the baffle has an "L" shaped structure, and two baffles are provided, and the two baffles are respectively fixedly connected to the two transmission sliders.

[0010] Furthermore, the guide adjustment assembly also includes: guide blocks and contact springs; the guide blocks are arranged in two sets, each set having three pieces, and the two sets of guide blocks are slidably connected inside the two baffles respectively; the contact springs are arranged in two sets, each set having three pieces, the upper ends of the two sets of contact springs are dispersedly and fixedly connected inside the baffles, and the lower ends of the two sets of contact springs are fixedly connected to the two sets of guide blocks respectively.

[0011] Furthermore, the spacing adjustment assembly includes: a second operating handwheel, a second transmission screw, and a connecting slider; the second operating handwheel is rotatably connected to the front of the support frame; the second transmission screw is coaxially fixedly connected to the right end of the second operating handwheel; the connecting slider is slidably connected inside the support frame, and the connecting slider is threadedly connected to the second transmission screw.

[0012] Furthermore, the spacing adjustment assembly also includes: a scissor mechanism, pressing rollers, and a guide rod; the front end of the scissor mechanism is rotatably connected to the connecting slider at its hinge, and the middle part of the scissor mechanism is rotatably connected to the inside of the support frame at its hinge; multiple pressing rollers are provided, and these multiple pressing rollers are rotatably connected below multiple hinge points of the scissor mechanism; the guide rod is fixedly connected to the inside of the support frame, and the multiple pressing rollers are slidably connected to the guide rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, by rotating the first operating handwheel, the baffles on both sides are driven to move inward or outward simultaneously, quickly adapting to gift boxes of different widths. The guide blocks inside the baffles are in elastic contact with the surface of the gift box through contact springs, which can both restrict the lateral movement of the gift box and adapt to the slight undulations of the conveyor belt, ensuring the guiding and positioning effect of the gift box.

[0015] Secondly, by turning the second operating handwheel, multiple pressing rollers can be driven to adjust the spacing synchronously along the guide rod. The design of the scissor mechanism ensures that the roller group moves synchronously when adjusting the spacing. The front and rear pressing rollers can cover and press the front and rear ends of cardboard boxes of different widths, eliminating the need to disassemble or add additional pressing rollers, making the operation faster.

[0016] This utility model can drive the two side baffles to move inward or outward synchronously, quickly adapting to gift boxes of different widths. The guide block makes elastic contact with the gift box through a contact spring, thereby adapting to the undulations of the conveyor belt and ensuring the guiding and positioning effect. The multiple pressing rollers can adjust their spacing synchronously along the guide rod to achieve covering and pressing of the front and rear ends of paper boxes of different widths. There is no need to disassemble and assemble the rollers separately, making the operation faster. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0026] Example 1:

[0027] As attached Figure 1 To be continued Figure 6 As shown:

[0028] This utility model provides an auxiliary positioning device for high-precision gift box lamination production, including a laminating machine body 1, a conveyor belt 2, a fixed plate 3, a transmission box 4, a first operating handwheel 5, a transmission worm gear 501, a support frame 10, and a guide adjustment assembly; the conveyor belt 2 is disposed inside the laminating machine body 1; the fixed plate 3 is fixedly connected inside the laminating machine body 1; the transmission box 4 is fixedly connected to the front of the fixed plate 3; the first operating handwheel 5 is rotatably connected to the right side of the transmission box 4; two transmission worm gears 501 are provided, the right transmission worm gear 501 is coaxially fixedly connected to the left side of the first operating handwheel 5, and the left transmission worm gear 501 is coaxially fixedly connected to the left end of the right transmission worm gear 501; three support frames 10 are provided, and the three support frames 10 are dispersedly fixedly connected to the fixed plate 3; two sets of guide adjustment assemblies are provided, and the two sets of guide adjustment assemblies are respectively disposed behind the two transmission worm gears 501.

[0029] The guide adjustment assembly includes: a transmission worm gear 6, a connecting shaft 7, and a first transmission screw 701; the transmission worm gear 6 is rotatably connected inside the transmission box 4 and meshes with the transmission worm 501; the connecting shaft 7 is rotatably connected inside the fixed plate 3; two first transmission screws 701 are provided, with opposite threads on their surfaces, the front first transmission screw 701 being coaxially fixed at its front and rear ends to the transmission worm 501 and the inner end of the connecting shaft 7 respectively, and the rear first transmission screw 701 being coaxially fixedly connected to the rear end of the connecting shaft 7.

[0030] The guide adjustment assembly also includes: a transmission slider 8 and a baffle 801; two transmission sliders 8 are provided, and the two transmission sliders 8 are slidably connected inside the fixed plate 3, and the two transmission sliders 8 are respectively threadedly connected to two first transmission screws 701; the baffle 801 has an "L" shaped structure, and two baffles 801 are provided, and the two baffles 801 are respectively fixedly connected to the two transmission sliders 8.

[0031] The guide adjustment assembly also includes: guide blocks 9 and contact springs 901; two sets of guide blocks 9 are provided, each set of guide blocks 9 has three pieces, and the two sets of guide blocks 9 are slidably connected inside the two baffles 801 respectively; two sets of contact springs 901 are provided, each set of contact springs 901 has three pieces, the upper ends of the two sets of contact springs 901 are dispersedly and fixedly connected inside the baffles 801, and the lower ends of the two sets of contact springs 901 are fixedly connected to the two sets of guide blocks 9 respectively.

[0032] The specific usage and function of this embodiment are as follows: When in use, if the width of the gift box changes, the first operating handwheel 5 is rotated, which simultaneously drives the two transmission worm gears 501 to rotate. The transmission worm gears 501 drive the two sets of first transmission screws 701 to rotate simultaneously through the worm gear transmission mechanism formed by meshing with the transmission worm wheel 6. The two sets of first transmission screws 701 drive the two baffles 801 to move simultaneously through the threaded transmission mechanism formed by the two sets of transmission sliders 8. Since the threads on the surfaces of the first transmission screws 701 at the front and rear ends are set oppositely, the movement direction of the two baffles 801 is simultaneously towards the inward or outward side. After the movement is completed, during the paper box transportation process, the multiple guide blocks 9 can make the paper box transported in the center on the conveyor belt 2. At the same time, the guide blocks 9 are connected to the baffles 801 through the contact springs 901. Therefore, the bottom of the guide blocks 9 will always be in contact with the surface of the conveyor belt 2, thereby adapting to the tension fluctuations of the conveyor belt 2 and ensuring the restriction effect on the position of the paper box.

[0033] Example 2:

[0034] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 6 The system also includes a spacing adjustment assembly, with three sets of the spacing adjustment assembly, each set being installed inside one of the three support frames 10.

[0035] The spacing adjustment assembly includes: a second operating handwheel 11, a second transmission screw 1101, and a connecting slider 12; the second operating handwheel 11 is rotatably connected to the front of the support frame 10; the second transmission screw 1101 is coaxially fixedly connected to the right end of the second operating handwheel 11; the connecting slider 12 is slidably connected inside the support frame 10, and the connecting slider 12 is threadedly connected to the second transmission screw 1101.

[0037] The specific usage and function of this embodiment: When in use, if the width of the cardboard box becomes narrower or wider, and the position of the multiple pressing rollers 14 cannot press the cardboard box from all directions, then the second operating handwheel 11 can be rotated. Through the threaded transmission mechanism formed by the second transmission screw 1101 and the connecting slider 12, the scissor mechanism 13 is driven to contract or extend. Thus, under the guidance of the guide rod 15, the distance between two adjacent pressing rollers 14 can be widened or narrowed at the same time. Therefore, without disassembling or adding pressing rollers 14, cardboard boxes of different widths can be pressed from all directions to prevent the cardboard box from undulating.
