Description

Technical Field

[0001] This utility model relates to the field of packaging technology for building material sales, specifically a packaging device for building material sales. Background Technology

[0002] In the field of building materials sales, cargo packaging equipment is a key piece of equipment to ensure the efficient operation of material transportation, storage and sales processes. By neatly bundling various building materials, it can effectively reduce the scattering and damage of materials during circulation, while improving transportation and loading efficiency. Among them, automatic strapping machines, as a highly automated packaging equipment, are widely used in the batch processing of building materials due to their fast strapping speed and stable strapping effect. They play an important role, especially in the pre-sales packaging of strip materials such as wood strips, square tubes, door and window profiles, stainless steel decorative strips, and aluminum alloy skirting boards. However, when handling strip materials such as wood strips, existing automatic strapping machines tend to have loose arrangement after the wood strips are placed on the worktable, with large gaps between adjacent strips, resulting in a loose overall structure. If directly strapped, this not only causes the material to shake during the strapping process, affecting the tightening effect of the strapping tape, but also results in poor overall structural stability after strapping. This makes the material prone to loosening during transportation and may even break due to uneven stress on the strapping tape, affecting packaging quality and transportation safety. Utility Model Content

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a goods packaging device for the sale of building materials. This device automatically tightens strip-shaped building materials before bundling, significantly reducing material gaps and improving bundling stability. It improves or solves, to some extent, the problems encountered by existing automatic bundling machines when handling strip-shaped materials such as wood strips. After the wood strips are placed on the worktable, they tend to be loosely arranged with large gaps between adjacent strips, resulting in a generally loose structure. Direct bundling not only causes the materials to wobble during the bundling process, affecting the tightening effect of the bundling straps, but also leads to poor overall structural stability after bundling. This makes the materials prone to loosening during transportation and may even cause breakage due to uneven stress on the bundling straps, affecting packaging quality and transportation safety.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein.

[0021] Example 1 Reference Figure 1-4 This is the first embodiment of the present utility model, which provides a goods packaging device for the sale of building materials, including a strapping machine body 1, a workbench 2 and a feeding tray 3. There are two workbench 2, which are respectively fixedly connected to the front and rear sides of the upper end of the strapping machine body 1. The feeding tray 3 is fixedly connected to the right side of the strapping machine body 1. The upper surface of the two workbench 2 is provided with a placement groove 4. The upper end of the two placement grooves 4 is fixedly connected with a sealing plate 5. The front and rear ends of the left and right sides of the upper surface of the sealing plate 5 are respectively provided with movable grooves 6, which penetrate into the interior of the placement groove 4. The interior of the two placement grooves 4 is provided with a tightening device 7. The clamping device 7 includes clamping components 8 and adjusting mechanism 9. There are two clamping components 8, which are respectively set on the left and right sides of the upper end of the placement groove 4. The adjusting mechanism 9 is set at the lower end of the placement groove 4.

[0022] Specifically, the automatic strapping machine, by setting a tightening device 7 on the workbench 2, can effectively tighten strip-shaped building materials such as wooden strips before strapping, greatly reducing the gap between materials and improving the structural stability and transportation safety after strapping.

[0023] Furthermore, the adjustment mechanism 9 drives the two clamping components 8 to move closer or separate from each other, achieving pre-tightening and loosening of the strip building material through mechanical linkage. The components work together to complete the tightening operation, providing a stable foundation for the subsequent bundling process.

[0024] Example 2 In the second embodiment of this utility model, limiting slide rods 10 are provided on both the front and rear sides of the upper end of the placement groove 4, and the left and right ends of the two limiting slide rods 10 are fixedly connected to the left and right side surfaces of the placement groove 4, respectively. The clamping assembly 8 includes a movable seat 81, a clamping plate frame 82, an extrusion groove 83, and auxiliary moving parts 84. The movable seat 81 is sleeved on the right end surface of the two limiting slide rods 10 and is slidably connected to the limiting slide rods 10. The upper ends of the front and rear sides of the movable seat 81 extend out of the worktable 2 through the two movable grooves 6 on the right side and are movably connected to the worktable 2. The clamping plate frame 82 is fixedly connected to the upper end of the movable seat 81. The extrusion groove 83 is opened on the front side of the lower surface of the movable seat 81. There are several auxiliary moving parts 84, which are evenly arranged inside the clamping plate frame 82. The auxiliary moving part 84 includes a rotating shaft 841 and a rubber roller 842. The rotating shaft 841 is disposed inside the clamping plate frame 82, and its upper and lower ends are rotatably connected to the upper and lower surfaces inside the clamping plate frame 82, respectively. The rubber roller 842 is sleeved on the surface of the rotating shaft 841 and is rotatably connected to the rotating shaft 841. The rubber rollers 842 inside the two clamping plate frames 82 extend out of each other from the side that is close to each other, and are movably connected to the clamping plate frames 82. Each of the upper parts of the movable groove 6 is provided with an elastic sealing gasket 11. The elastic sealing gasket 11 is fixedly connected to the inner wall of the movable groove 6, and is sleeved on the upper surface of the movable seat 81 and fixedly connected to the movable seat 81.

[0025] Specifically, by setting up the clamping component 8, the limiting slide bar 10 and the elastic sealing gasket 11 together, the wooden strips can be stably clamped to achieve pre-tightening, the damage to the wood surface can be reduced and the internal cleanliness of the equipment can be ensured, and the movement and adjustment of the wooden strips can be maintained.

[0026] Furthermore, the two L-shaped bending parts 912 rotate and approach each other with the two rotating rods 911 as fulcrums. While rotating, they will drive the two pressure rods 913 to move and press the inner walls of the two extrusion grooves 83 together inside the two extrusion grooves 83. This will cause the two moving seats 81 to be subjected to the extrusion force and slide along the limiting slide rod 10 to the middle position, thereby driving the upper clamping plate frame 82 to move closer to the wooden strip to clamp and tighten it. While clamping and tightening the wooden strips, multiple rotating shafts 841 inside the clamping frame 82 move with the frame. Rubber rollers 842, which are sleeved on the surface of the rotating shafts 841, come into contact with the surface of the wood. While clamping and tightening, the rubber material reduces frictional damage to the surface of the wood during the clamping process. When the two clamping frames 82 tighten the wood to a preset degree, the control motor 924 stops running, completing the pre-tightening operation. At this time, the wood is stably clamped, and the gap between adjacent wooden strips is eliminated, providing a solid foundation for the subsequent binding process. At the same time, the auxiliary moving part 84 can also move the auxiliary wooden strips after the wooden strips are clamped. When it is necessary to adjust the front and rear binding position of the wooden strips on the worktable 2, the wooden strips are pushed to move. The rubber rollers 842 can rotate flexibly with the movement of the wooden strips, reducing the frictional resistance between the wooden strips and the clamping frame 82 when they move. At the same time, when the movable seat 81 moves, the upper ends of its front and rear sides slide synchronously through the movable groove 6. The elastic sealing gasket 11 in the movable groove 6 deforms with the displacement of the movable seat 81, tightly adhering to the surface of the movable seat 81, preventing dust and debris in the placement groove 4 from entering the equipment through the gaps in the movable groove 6.

[0027] Example 3 In the third embodiment of this utility model, the adjustment mechanism 9 includes a linkage component 91 and a control component 92. There are two linkage components 91, which are respectively arranged below the two movable seats 81 and correspond to the two extrusion grooves 83. The control component 92 is arranged between the lower ends of the two linkage components 91. The linkage component 91 includes a rotating rod 911, an L-shaped bent part 912, a pressure rod 913, and a stroke groove 914. The rotating rod 911 is located below the rear side of the movable seat 81 and is fixedly connected to the bottom surface inside the mounting groove 4. The middle end of the L-shaped bent part 912 is sleeved on the upper surface of the rotating rod 911 and is rotatably connected to the rotating rod 911. The pressure rod 913 is fixedly connected to the front end of the L-shaped bent part 912, and its upper end is located inside the extrusion groove 83 and is movably connected to the extrusion groove 83. The stroke groove 914 is opened on the left side of the rear end of the L-shaped bent part 912. The control component 92 includes a slide rail 921, a slide plate 922, a pull rod 923, a motor 924, and a screw 925. There are two slide rails 921, which are fixedly connected to the left and right sides of the bottom surface of the mounting groove 4, respectively. The slide plate 922 is fitted onto the rear end surface of the two slide rails 921 and is slidably connected to the slide rails 921. There are two pull rods 923, which are fixedly connected to the left and right sides of the upper surface of the slide plate 922, respectively. The upper ends of the two pull rods 923 are respectively set inside the two travel grooves 914 and are movably connected to the travel grooves 914. The motor 924 is fixedly connected to the front side of the bottom surface inside the mounting groove 4. The screw 925 is fixedly connected to the rear output end of the motor 924, and its rear end passes through the slide plate 922 and is rotatably connected to the rear surface inside the mounting groove 4. The screw 925 is threadedly connected to the slide plate 922.

[0028] Specifically, by setting up the adjustment mechanism 9, the linkage component 91 and the control component 92 work together to simultaneously link the two clamping components 8 to open and close, completing the clamping and loosening operation of the wooden strip, which facilitates the clamping and subsequent release operation.

[0029] Furthermore, after placing the front end of the wood on the workbench 2 between the two clamping frames 82, the motor 924 is controlled to drive the screw 925 to rotate. As the screw 925 rotates, because it is threadedly connected to the slide plate 922 and the slide plate 922 is fitted onto the two slide rails 921, it drives the slide plate 922 to slide backward along the slide rails 921. The pull rods 923 on the left and right sides of the upper surface of the slide plate 922 move synchronously with the slide plate 922, and the upper ends of the two pull rods 923 are embedded in the rear ends of the two L-shaped bent parts 912. Within the stroke groove 914, the L-shaped bending piece 912 is pushed by moving and pressing the inner wall of the stroke groove 914, causing the two L-shaped bending pieces 912 to rotate and approach each other with the two rotating rods 911 as fulcrums. At the same time, the rotation will drive the two pressure rods 913 to move and press the inner walls of the two pressing grooves 83 together, causing the two moving seats 81 to be pushed by the pressure and slide along the limiting slide rod 10 to the middle position, thereby driving the upper clamping plate frame 82 to move closer to the wooden strip to clamp and tighten it.

[0030] Working principle: In use, the front end of the wood is placed on the workbench 2, between the two clamping frames 82. The motor 924 is then used to drive the screw 925 to rotate. As the screw 925 rotates, it is threadedly connected to the slide plate 922, which is fitted onto the two slide rails 921. This causes the slide plate 922 to slide backward along the slide rails 921. The pull rods 923 on the left and right sides of the upper surface of the slide plate 922 move synchronously with it. The upper ends of the two pull rods 923 are embedded in the rear ends of the two L-shaped bent parts 912. Within the stroke groove 914, the L-shaped bending piece 912 is pushed by moving and pressing the inner wall of the stroke groove 914, causing the two L-shaped bending pieces 912 to rotate and approach each other with the two rotating rods 911 as fulcrums. At the same time, the rotation will drive the two pressure rods 913 to move and press the inner walls of the two pressing grooves 83 together, causing the two moving seats 81 to be subjected to the pressing force and slide along the limiting slide rod 10 to the middle position, thereby driving the upper clamping plate frame 82 to move closer to the wooden strip to clamp and tighten it. While clamping and tightening the wooden strips, multiple rotating shafts 841 inside the clamping frame 82 move with the frame. Rubber rollers 842, which are sleeved on the surface of the rotating shafts 841, come into contact with the surface of the wood. While clamping and tightening, the rubber material reduces frictional damage to the surface of the wood during the clamping process. When the two clamping frames 82 tighten the wood to a preset degree, the control motor 924 stops running, completing the pre-tightening operation. At this time, the wood is stably clamped, and the gap between adjacent wooden strips is eliminated, providing a solid foundation for the subsequent binding process. At the same time, the auxiliary moving part 84 can also move the auxiliary wooden strips after the wooden strips are clamped. When it is necessary to adjust the front and rear binding position of the wooden strips on the worktable 2, the wooden strips are pushed to move. The rubber rollers 842 can rotate flexibly with the movement of the wooden strips, reducing the frictional resistance between the wooden strips and the clamping frame 82 when they move. At the same time, when the movable seat 81 moves, the upper ends of its front and rear sides slide synchronously through the movable groove 6. The elastic sealing gasket 11 in the movable groove 6 deforms with the displacement of the movable seat 81, tightly adhering to the surface of the movable seat 81, preventing dust and debris in the placement groove 4 from entering the equipment through the gap of the movable groove 6. When the clamping is released, the control motor 924 reverses to drive the screw 925 to rotate in the opposite direction, driving the slide plate 922 to slide forward along the slide rail 921. The pull rod 923 moves forward with the slide plate 922 and squeezes the stroke groove 914 to pull the L-shaped bending piece 912 to rotate in the opposite direction with the rotating rod 911 as the fulcrum. The two L-shaped bending pieces rotate in the opposite direction, driving the two pressure rods 913 to squeeze the inner walls of the two compression grooves 83 to the left and right sides. This causes the two moving seats 81 to be subjected to the compression thrust and move away from the left and right sides along the limiting slide rod 10. The clamping frame 82 then separates, releasing the clamping state of the wood strips so that the bundled wood can be taken out.

[0031] In summary, by using the bundled machine body 1, workbench 2, feeding tray 3, placement slot 4, sealing plate 5, movable slot 6, tightening device 7, clamping assembly 8, moving seat 81, clamping plate frame 82, extrusion slot 83, auxiliary moving part 84, rotating shaft 841, rubber roller 842, adjusting mechanism 9, linkage assembly 91, rotating rod 911, L-shaped bending part 912, pressure rod 913, stroke slot 914, control assembly 92, slide rail 921, sliding plate 922, pull rod 923, motor 924, screw 925, limit slide rod 10, and elastic sealing gasket 11 in combination, the automatic tightening of strip building materials before bundling is achieved, significantly reducing material gaps and improving bundling stability.
