Description

Technical Field

[0001] This utility model relates to the field of heat sealing machine technology, and in particular to a leveling mechanism for an environmentally friendly heat sealing machine for plastic products. Background Technology

[0002] With the booming development of the plastic products processing industry, the quality requirements for plastic products are becoming increasingly stringent. As a key step in the molding of plastic products, heat sealing can make the materials bond tightly. However, due to factors such as uneven temperature and pressure, unevenness such as wrinkles and deformation often occur on the surface of plastic products during the heat sealing process. These defects not only affect the appearance of plastic products and reduce their market competitiveness, but may also cause stress concentration during subsequent use and shorten the product's life.

[0003] Currently, traditional leveling methods mostly rely on manual operation of simple tools, which is inefficient and produces unstable leveling results, making it difficult to meet the needs of large-scale, high-precision production. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem of low efficiency in leveling by manually operating simple tools in the existing technology, and to propose a leveling mechanism for an environmentally friendly heat sealing machine for plastic products.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a leveling mechanism for an environmentally friendly heat sealing machine for plastic products, comprising a worktable, support rods symmetrically fixedly installed at the bottom of the worktable, connecting rods symmetrically fixedly installed on both sides of the worktable, a top plate fixedly installed at the top of the connecting rods, a hydraulic cylinder fixedly installed at the top of the top plate, a heat sealing plate fixedly installed at the output end of the hydraulic cylinder, a fixed frame fixedly installed at the bottom of the worktable, a drive motor one fixedly installed at one end of the fixed frame, a threaded rod fixedly installed at the output end of the drive motor one, a long plate threadedly connected to the outer wall of the threaded rod, a toothed rod slidably connected inside the long plate, a connecting frame fixedly installed on one side of the top of the toothed rod, a leveling roller rotatably connected inside the connecting frame, an L-plate fixedly installed on one side of the long plate, a drive motor two fixedly installed on one side of the L-plate, and a gear fixedly installed at the output end of the drive motor two.

[0006] Preferably, the gear and the rack mesh with each other, and the long plate and the fixed frame are slidably connected.

[0007] Preferably, a limiting plate is fixedly installed at the bottom of the toothed rod, and a pad is fixedly installed at the bottom end of the support rod.

[0008] Preferably, the top of the heat-sealed plate is symmetrically fixedly installed with connecting columns, the top of the connecting columns is fixedly installed with limiting round blocks, and the outer wall of the connecting columns is sleeved with buffer springs.

[0009] Preferably, one end of the buffer spring is fixedly connected to the limiting block, and the other end of the buffer spring is fixedly connected to the top plate.

[0010] Preferably, the connecting column and the top plate are slidably connected.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, by cooperating with the second drive motor and gears and racks, the leveling roller can be precisely controlled to move downward and fit against the plastic product, ensuring the accuracy of the initial leveling position and laying the foundation for subsequent effective leveling. By driving the first drive motor to rotate the threaded rod, the long plate is moved laterally using the thread transmission principle, which in turn drives the leveling roller to move synchronously. This design can efficiently level the wrinkles on the surface of the plastic product, ensure the appearance quality of the product, improve the yield rate, reduce the scrap loss caused by appearance defects, and effectively avoid the problem of low efficiency of manual operation of simple tools for leveling.

[0013] 2. In this utility model, by placing the plastic product on the workbench and then activating the hydraulic cylinder, the output end of the cylinder will push the heat-sealing plate downward. During the downward movement of the heat-sealing plate, the connecting column will slide along the corresponding hole on the top plate, providing guidance for the movement of the heat-sealing plate. At the same time, the buffer spring sleeved on the outer wall of the connecting column is compressed. The buffer spring plays a crucial role in buffering, absorbing the impact force when the heat-sealing plate moves downward, avoiding damage to the plastic product or the heat-sealing plate itself due to rigid contact, and ensuring that the heat-sealing pressure is applied evenly.

[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0019] 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. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0020] Example 1: As Figures 1-3 As shown, this utility model provides a technical solution: a leveling mechanism for an environmentally friendly heat sealing machine for plastic products, including a worktable 1, support rods 2 symmetrically fixedly installed at the bottom of the worktable 1, connecting rods 3 symmetrically fixedly installed on both sides of the worktable 1, a top plate 4 fixedly installed at the top of the connecting rods 3, a hydraulic cylinder 5 fixedly installed at the top of the top plate 4, a heat sealing plate 6 fixedly installed at the output end of the hydraulic cylinder 5, a fixing frame 7 fixedly installed at the bottom of the worktable 1, a drive motor 8 fixedly installed at one end of the fixing frame 7, a threaded rod 9 fixedly installed at the output end of the drive motor 8, and the outer wall of the threaded rod 9... A long plate 10 is threadedly connected, and a toothed rod 11 is slidably connected inside the long plate 10. A connecting frame 12 is fixedly installed on one side of the top of the toothed rod 11. A leveling roller 13 is rotatably connected inside the connecting frame 12. An L-plate 14 is fixedly installed on one side of the long plate 10. A second drive motor 15 is fixedly installed on one side of the L-plate 14. A gear 16 is fixedly installed at the output end of the second drive motor 15. The gear 16 meshes with the toothed rod 11. The long plate 10 is slidably connected to the fixed frame 7. A limit plate 17 is fixedly installed at the bottom of the toothed rod 11. A pad 21 is fixedly installed at the bottom end of the support rod 2.

[0021] In this embodiment, the drive motor 15, in conjunction with the gear 16 and rack 11, can precisely control the downward movement of the leveling roller 13 to fit against the plastic product, ensuring accurate initial leveling position and laying the foundation for subsequent effective leveling. The drive motor 8 drives the threaded rod 9 to rotate, and the threaded transmission principle is used to move the long plate 10 laterally, thereby driving the leveling roller 13 to move synchronously. This design can efficiently level wrinkles on the surface of plastic products, ensuring product appearance quality, improving yield, reducing scrap losses caused by appearance defects, and effectively avoiding the problem of low efficiency in leveling by manually operating simple tools.

[0022] Example 2: Figure 1As shown, a connecting column 18 is symmetrically fixedly installed on the top of the heat-sealed plate 6. A limiting block 19 is fixedly installed on the top of the connecting column 18. A buffer spring 20 is sleeved on the outer wall of the connecting column 18. One end of the buffer spring 20 is fixedly connected to the limiting block 19, and the other end of the buffer spring 20 is fixedly connected to the top plate 4. The connecting column 18 and the top plate 4 are slidably connected.

[0023] In this embodiment, by placing the plastic product on the workbench 1, the hydraulic cylinder 5 is activated, and its output end pushes the heat-sealing plate 6 downward. During the downward movement of the heat-sealing plate 6, the connecting column 18 slides along the corresponding hole on the top plate 4, providing guidance for the movement of the heat-sealing plate 6. At the same time, the buffer spring 20 sleeved on the outer wall of the connecting column 18 is compressed. The buffer spring 20 plays a crucial buffering role. It can absorb the impact force when the heat-sealing plate 6 moves downward, avoid damage to the plastic product or the heat-sealing plate 6 itself due to rigid contact, and ensure that the heat-sealing pressure is applied evenly.

[0024] The working principle of this embodiment is as follows: When in use, the plastic product is first placed on the workbench 1. After placement, the hydraulic cylinder 5 is started, and its output end will push the heat-sealing plate 6 downward. During the downward movement of the heat-sealing plate 6, the connecting column 18 will slide along the corresponding hole on the top plate 4 to guide the movement of the heat-sealing plate 6. At the same time, the buffer spring 20 sleeved on the outer wall of the connecting column 18 is compressed. The buffer spring 20 plays a crucial role in buffering. It can absorb the impact force when the heat-sealing plate 6 moves downward, avoid damage to the plastic product or the heat-sealing plate 6 itself due to rigid contact, and ensure that the heat-sealing pressure is applied evenly. After the heat-sealing plate 6 moves downward a certain distance, it will heat-seal the plastic product on the workbench 1. After heat sealing is completed, the hydraulic cylinder 5 is controlled to return the heat-sealing plate 6 to its original position. If wrinkles, deformation, or other unevenness are found on the surface of the heat-sealed plastic product after restoration, the drive motor 15 can be started. When the drive motor 15 is working, it will drive the gear 16 to rotate. During the rotation of the gear 16, it will drive the meshing toothed rod 11 to slide downward inside the long plate 10. During the downward sliding of the toothed rod 11, it will drive the leveling roller 13 installed through the connecting frame 12 to move downward synchronously. After moving downwards a certain distance, the leveling roller 13 will adhere to the heat-sealed plastic product. After adhesion, the drive motor 8 will be started. When the drive motor 8 is working, it will drive the threaded rod 9 to rotate. Since the threaded rod 9 is threadedly connected to the long plate 10, and the long plate 10 is constrained within the fixed frame 7 and can only slide in a straight line, under the action of the thread transmission principle, the long plate 10 moves laterally along the fixed frame 7. When the long plate 10 moves, it will drive the leveling roller 13 installed through the connecting frame 12 to move synchronously. During the movement, the leveling roller 13 can level the wrinkles on the surface of the plastic product.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
