Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to an automatic wrapping and packaging device for gypsum board. Background Technology

[0002] Publication number "CN217477606U" discloses an automatic wrapping and packaging device for gypsum board, including a base, a first L-shaped plate, and a second L-shaped plate. The first L-shaped plate and the second L-shaped plate are located on both sides of the base. A cylinder is located on the inner side of the top of the second L-shaped plate. A rotating seat is located at the output end of the cylinder. A connecting plate is located at one end of the rotating seat. A connecting disk is located on one side of the connecting plate. The connecting disk is rotatably connected to the rotating seat via a rotating shaft. A clamping plate is located on the side of the connecting plate away from the connecting disk. Multiple telescopic rods are evenly connected between the connecting plate and the clamping plate. The two ends of the telescopic rods are respectively connected to the connecting plate and the clamping plate. A spring is sleeved on the outer side of the telescopic rod. A rotating motor is located at the top of the base below the clamping plate. The drive shaft of the rotating motor is connected to the rotating disk. This utility model eliminates the need for manual film coating, has a good fixing effect, and improves the film coating quality.

[0003] However, the above technologies cannot guarantee that the center of the gypsum board will always correspond to the center of the rotating disk when placing the gypsum board. If the gypsum board rotates eccentrically, the linear velocity of different points on its surface will be inconsistent. The linear velocity is lower on the side closer to the center of rotation and higher on the side farther from the center of rotation. This will cause different degrees of stretching on the surface of the gypsum board when the film is applied. The film may wrinkle near the center of rotation because the rotation speed of this part of the gypsum board is relatively slow, and the film cannot be stretched and unfolded well. On the other hand, the film may be overstretched in the part farther from the center of rotation, and may even tear, affecting the flatness and integrity of the coating. Utility Model Content

[0004] To address the problem that the gypsum board cannot be guaranteed to align perfectly with the center of the rotating disk each time it is placed, the purpose of this invention is to provide an automatic wrapping and packaging device for gypsum boards.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: an automatic wrapping and packaging device for gypsum board, comprising a base, a rotating motor fixedly installed on one side of the top of the base, a rotating shaft fixedly installed on the drive end of the rotating motor, a rotating plate fixedly installed on the top of the rotating shaft, a cross plate provided on the top of the rotating plate, and fixing blocks fixedly installed at the four corners of the top of the cross plate. A first double-ended screw with opposite threads is rotatably threaded through the tops of the two fixing blocks on the left and right sides. A first movable plate is threaded to the outer side of the first double-ended screw. A double-ended screw is rotatably threaded through the bottoms of the two fixing blocks on the front and rear sides. A second double-ended screw with opposite threads has two symmetrically distributed second movable plates connected to its outer threads. A turntable is fixedly mounted at one end of both the first and second double-ended screws. A handle is fixedly mounted on the side of the turntable away from the fixed block. Two sets of symmetrically distributed support legs are fixedly mounted on the upper surface of the turntable. A placement plate is fixedly mounted at the top of each support leg. A first slot for use with the first movable plate is formed through the top of the placement plate, and a second slot for use with the second movable plate is formed through the upper surface of the placement plate. The first double-ended screw is located above the second double-ended screw.

[0006] Preferably, a rubber pad is fixedly installed on the side of each of the first and second movable plates away from the fixed block.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0008] 1. This application ensures that the center position of the gypsum board always corresponds to the center position of the placement board each time it is placed on the placement board, thus avoiding the center position of the gypsum board from shifting and affecting the flatness and integrity of the film. At the same time, it can accommodate gypsum boards of different sizes.

[0009] 2. This application avoids damage to the surface of the gypsum board caused by the first and second movable boards when the gypsum board is placed. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example: Figure 1-3 As shown, this utility model provides an automatic wrapping and packaging device for gypsum board, including a base 1. A rotary motor 11 is fixedly installed on one side of the top of the base 1. A rotating shaft 12 is fixedly installed on the drive end of the rotary motor 11. A rotating plate 13 is fixedly installed on the top of the rotating shaft 12. A cross plate 14 is provided on the top of the rotating plate 13. Fixing blocks 15 are fixedly installed at the four corners of the top of the cross plate 14. The tops of the two fixing blocks 15 on the left and right sides are rotatably connected to the first double-ended screws 16 with opposite threads at both ends. The outer threads of the first double-ended screws 16 are connected to the first moving plate 17. The bottoms of the two fixing blocks 15 on the front and rear sides are rotatably connected to the second double-ended screws 18 with opposite threads at both ends. The outer side of the second double-ended screw 18 is threaded with two symmetrically distributed second moving plates 19. A turntable 2 is fixedly installed at one end of both the first double-ended screw 16 and the second double-ended screw 18. A handle 21 is fixedly installed on the side of the turntable 2 away from the fixed block 15. Two sets of symmetrically distributed support legs 22 are fixedly installed on the upper surface of the turntable 13. A placement plate 23 is fixedly installed at the top of the support legs 22. A first slot 24 for cooperating with the first moving plate 17 is opened through the top of the placement plate 23. A second slot 25 for cooperating with the second moving plate 19 is opened through the upper surface of the placement plate 23. The first double-ended screw 16 is located above the second double-ended screw 18.

[0017] Each of the first movable plate 17 and the second movable plate 19 has a rubber pad 3 fixedly installed on the side away from the fixed block 15.

[0018] Each of the first moving plate 17 and the second moving plate 19 has a T-shaped block 4 fixedly installed at its bottom end. The upper surface of the cross plate 14 is provided with a limiting groove 41 that cooperates with the T-shaped block 4. By setting the T-shaped block 4 and the limiting groove 41, the first moving plate 17 is limited to prevent it from rotating with the rotation of the first double-headed screw 16, which would affect the first moving plate 17 from moving to the middle or to the sides. Similarly, the second moving plate 19 is prevented from rotating with the rotation of the second double-headed screw 18, which would affect the second moving plate 19 from moving to the middle or to the sides.

[0019] An electric telescopic rod 5 is fixedly installed at the top center of the rotating plate 13. The drive end of the electric telescopic rod 5 is fixedly connected to the cross plate 14. By setting the electric telescopic rod 5, when the electric telescopic rod 5 is started, it drives the cross plate 14 to rise, so that the tops of the first moving plate 17 and the second moving plate 19 pass through the placement plate 23, thereby positioning the gypsum board. After positioning is completed, when the gypsum board needs to be automatically wrapped and packaged, the electric telescopic rod 5 drives the cross plate 14 to move down, so that the top surfaces of the first moving plate 17 and the second moving plate 19 are flush with the top surface of the placement plate 23, thus avoiding the first moving plate 17 and the second moving plate 19 affecting the automatic wrapping of the gypsum board during the automatic wrapping and packaging.

[0020] Two symmetrically distributed telescopic rods 51 are fixedly installed at the bottom of the cross plate 14. The bottom of the telescopic rods 51 are fixedly connected to the rotating plate 13. By setting the telescopic rods 51, the cross plate 14 becomes more stable when it rises or falls.

[0021] A controller 52 is fixedly installed at the top edge of the rotating plate 13. The controller 52 is electrically connected to the electric telescopic rod 5. By setting the controller 52, it is easier to control the start and stop of the electric telescopic rod 5.

[0022] A U-shaped support frame 6 is rotatably mounted on the outside of the rotating shaft 12. The bottom end of the U-shaped support frame 6 is fixedly connected to the base 1. The rotating plate 13 is in contact with the U-shaped support frame 6. By setting the U-shaped support frame 6, the rotating plate 13 is supported, making the rotating plate 13 more stable when rotating.

[0023] A rubber sleeve 7 is fixedly installed on the outside of the handle 21. The rubber sleeve 7 can be a rubber sleeve with rubber particles. By setting the rubber sleeve 7, the comfort between the hand and the handle 21 is increased. Furthermore, by using a rubber sleeve 7 with rubber particles, slippage is prevented when rotating the rubber sleeve 7, thus making it easier to rotate the handle 21.

[0024] Working principle: In actual use, first place the plasterboard on board 23, then raise the cross plate 14 so that the top surfaces of the first moving plate 17 and the second moving plate 19 exceed the top surface of the board 23. Then, turn the two handles 21 respectively, driving the corresponding turntable 2 to rotate, thereby driving the first double-ended screw 16 to rotate. Since the threads of the two ends of the first double-ended screw 16 are opposite, when rotating, it will cause the two first moving plates 17 to move to the sides or to the middle, so that the rubber pads 3 on the first moving plates 17 are in contact with the left and right sides of the plasterboard. Similarly, the rotation of the turntable 2 drives the second double-ended screw 18 to rotate. The double-ended screw 18 has opposite threads at both ends. When it rotates, it causes the two second moving plates 19 to move to the sides or towards the center, so that the rubber pads 3 on the second moving plates 19 fit against the front and back sides of the gypsum board. This ensures that when gypsum boards of different sizes are placed on the placement plate 23, the center position of the gypsum board is always in one place. When the distance between the first moving plate 17 and the second moving plate 19 is adjusted, and the automatic wrapping of the gypsum board begins, the first moving plate 17 and the second moving plate 19 are moved down away from the gypsum board. Each time a gypsum board is placed, the cross plate 14 needs to be placed on it, and then the cross plate 14 is moved down.

[0025] The winding assembly and fixing mechanism are described in this publication number CN217477606U, therefore, they will not be described here. The fixing assembly is shown in the accompanying drawings.

[0026] Turning the handle rotates the first and second double-ended screws. Because the threads on the two ends of the first double-ended screw are opposite, rotation causes the two first moving plates to move towards or away from each other; similarly, rotation of the second double-ended screw causes the two second moving plates to move towards or away from each other. In this way, the positions of the first and second moving plates are adjusted according to the size of the plasterboard, ensuring they fit tightly against the side of the plasterboard and achieving clamping and fixing. Simultaneously, the T-shaped blocks at the bottom of the first and second moving plates slide within the limiting grooves on the cross plate, ensuring that the moving plates can only move linearly and do not rotate with the screws.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
