Description

Technical Field

[0001] The utility model relates to the technical field of bag production, in particular to a workbench for bag production. Background Art

[0002] Bag manufacturing is a complex process involving multiple steps, including design, material preparation, cutting, punching, sewing, assembly, and quality inspection. Throughout these steps, the workbench, as an important auxiliary device, plays an indispensable role. It is primarily used to support and secure various tools and materials used in the bag production process, allowing operators to work in a stable and comfortable environment.

[0003] Existing workbenches for luggage production often fail to properly secure luggage, especially during the production of trolley cases, which can affect cutting and punching. For example, utility model patent application number 202223060338.5 discloses a workbench for luggage production, comprising a workbench and a processing plate. The processing plate is rotatably mounted on the upper end of the workbench via a bearing. An L-shaped frame is mounted on the upper end of the workbench. A control cylinder is mounted on the bottom inner end of the L-shaped frame. A pressing head is rotatably mounted on the output end of the control cylinder via a bearing.

[0004] While the aforementioned patent's technical solution utilizes a rotatable processing plate to process other sidewalls of the suitcase, eliminating the need for workers to repeatedly move around and improving work efficiency, this solution, however, relies solely on a control cylinder at the top of the workbench to drive a pressing head to press and secure the middle of the suitcase. When punching or trimming the sidewalls using punching or trimming equipment, the soft texture of the suitcase can easily lead to displacement and deformation, thus affecting production quality.

[0005] Therefore, it is necessary to develop a workbench for bag production to address the above-mentioned defects. Utility Model Content

[0024] With reference to the accompanying drawings, Figure 1 This is a schematic diagram of the top view of the workbench for producing bags and cases of the present invention; Figure 2 for Figure 1 Schematic diagram of the cross-sectional structure at AA in the middle; Figure 3 for Figure 1 A partial enlarged view of part I in the middle.

[0025] In one embodiment, Figures 1 to 3 As shown, the workbench 1 includes a rotating square plate 2 rotatably connected to the middle of the top surface of the workbench 1. The top surface of the rotating square plate 2 is provided with a positioning mechanism 3. The positioning mechanism 3 includes a first drive unit, a second drive unit, a mounting plate 301, and a limit plate 302. The two mounting plates 301 are arranged parallel to each other along the length of the rotating square plate 2 and are slidably connected to the rotating square plate 2. Four limit plates 302 are symmetrically slidably connected to the two mounting plates 301 in pairs. The first drive unit synchronously drives the two limit plates 302 on each mounting plate 301 to move in opposite directions on the mounting plates 301.

[0026] The present invention, through the arrangement of a first drive unit, a second drive unit, a mounting plate 301, and a limiting plate 302, can support and secure a suitcase from within. Depending on the size of the suitcase, the first drive unit synchronously drives the two limiting plates 302 on the two mounting plates 301 to move in opposite directions, adjusting the spacing between the two limiting plates 302 on the same mounting plate 301. The second drive unit drives the two mounting plates 301 to move in opposite directions along the width direction of the rotating square plate 2, adjusting the spacing between the two limiting plates 302 on different mounting plates 301. The spacing between the four limiting plates 302 is matched to the dimensions of the suitcase's interior, supporting and securing the four corners of the suitcase from within, improving the securing effect and preventing displacement and deformation during the suitcase's production and processing, which could affect the suitcase's production quality.

[0027] In a specific embodiment, the first drive unit includes a first servo motor 303, a first bidirectional screw rod 304, a first slider 305, a connecting plate 306 and a connecting column 307; the top surfaces of the two mounting plates 301 are provided with a slide groove 308, and the two ends of the first bidirectional screw rod 304 are rotatably connected to the side walls of the slide groove 308; the first servo motor 303 is fixedly connected to the outer wall of the mounting plate 301 and the output end shaft is coaxially fixedly connected to the first bidirectional screw rod 304; the two first sliders 305 are respectively threadedly connected to the positive and negative thread sections of the first bidirectional screw rod 304; the bottom surface of the connecting plate 306 is fixedly connected to the top surface of the first slider 305, the bottom surface of the connecting column 307 is fixedly connected to the top surface of the connecting plate 306, and the bottom surface of the limit plate 302 is fixedly connected to the top surface of the connecting column 307.

[0028] The first bidirectional screw rod 304 can be driven to rotate by the first servo motor 303, and the two first sliders 305 are threadedly connected to the forward and reverse thread segments of the first bidirectional screw rod 304, driving the two first sliders 305 to move in opposite directions along a straight line in the slide groove 308, and further driving the limit plate 302 fixedly connected to the slider 305 through the connecting plate 306 and the connecting column 307 to move in opposite directions along a straight line on the mounting plate 301, thereby adjusting the distance between the two limit plates 302 on the same mounting plate 301.

[0029] It should be noted that the first servo motors 303 on the two mounting plates 301 are controlled to move synchronously through the control system, so that the limiting plates 302 on the two mounting plates 301 can move synchronously.

[0030] In a specific embodiment, the second drive unit includes a second servo motor 309, a second bidirectional screw rod 310 and a second slider 311; the rotating square plate 2 is fixedly connected to the middle position of the front and rear ends with a support 312, and the second bidirectional screw rod 310 is horizontally mounted on the two supports 312; the second servo motor 309 is fixedly connected to the outer wall of the support 312 and the output end shaft is coaxially fixedly connected to the second bidirectional screw rod 310; the two second sliders 311 are respectively fixedly connected to the middle position of the bottom surface of the two mounting plates 301, and the two second sliders 311 are respectively threadedly connected to the forward and reverse thread sections of the second bidirectional screw rod 310.

[0031] The second bidirectional screw rod 310 can be driven to rotate by the second servo motor 309, and the two second sliders 311 are threadedly connected to the positive and negative threaded ends of the second bidirectional screw rod 310, driving the two mounting plates 301 fixedly connected to the two second sliders 311 to move in opposite directions along a straight line, thereby adjusting the distance between the limit plates 302 on different mounting plates 301.

[0032] Specifically, two parallel mounting bosses 313 are fixedly connected along the width direction on the left and right sides of the rotating square plate 2, and a guide rail 314 is fixedly connected to the top surface of each mounting boss 313. A third slider 315 is slidably connected to the front and rear ends of each guide rail 314, and the third slider 315 is fixedly connected to the two sides of the bottom surface of the two mounting plates 301 respectively.

[0033] Through such an arrangement, the guide rail 314 and the third slider 315 can support both sides of the mounting plate 301 , and at the same time can guide the movement of the mounting plate 301 , so that the mounting plate 301 can move better under the drive of the second bidirectional screw rod 310 .

[0034] In a specific embodiment, the positioning member includes a limiting column 316, a threaded hole 318 is provided at the top of the limiting column 316, an adjustment plate 319 is provided at the top of the limiting column 316, a strip-shaped movable groove 320 is provided in the middle position of the adjustment plate 319, and a rubber pad 317 is fixedly connected to one end of the top surface of the adjustment plate 319.

[0035] This arrangement avoids the problem of unstable support for the suitcase, which may occur if the limiting post 316 is directly used for support, as the top corners of the suitcase are usually rounded. By moving or rotating the adjustment plate 319 at the top of the limiting post 316, the threaded hole 318 on the limiting post 316 is adjusted to the position of the movable groove 320, thereby adjusting the position of the rubber pad 317 on the adjustment plate 319 on the suitcase. This allows the rubber pad 317 to be supported in a flat position near the corner of the top wall of the suitcase, thereby improving the stability of the support for the suitcase. The adjustment plate 319 is then fixed to the limiting post 316 by screwing the screw 321 through the movable groove 320 and into the threaded hole 318 of the limiting post 316.

[0036] Specifically, two pillars 4 are vertically provided in the middle of the rotating square plate 2 , and the top ends of the pillars 4 are horizontally fixedly connected with support plates 5 ; the end faces of the support plates 5 and the end faces of the rubber pads 317 are at the same height.

[0037] By providing the support plate 5, the middle position of the top wall of the trolley case can be supported and fixed, thereby further improving the fixing effect of the trolley case.

[0038] Working principle of the present invention: The present invention is a workbench for producing luggage. Taking a trolley case as an example, the trolley case is divided into an upper and lower box shells before assembly.

Reverse movement, thereby adjusting the distance between the two limit plates 302 on the same mounting plate 301. Then, the second servo motor 309 is turned on to drive the second bidirectional screw 310 to rotate. The two second sliders 311 are threadedly connected to the positive and negative threaded ends of the second bidirectional screw 310, driving the two mounting plates 301 fixedly connected to the two second sliders 311 to move in opposite directions along a straight line, thereby adjusting the distance between the limit plates 302 on different mounting plates 301. With the open end of the trolley case shell 6 facing downward, it is buckled onto the four limit plates 302, so that the limit plates 302 support and fix the four corners of the inner wall of the trolley case.
