Description

Technical Field

[0001] This utility model relates to the field of refrigerated truck body panel production technology, and specifically discloses a hot pressing device for refrigerated truck body panel production. Background Technology

[0002] Refrigerated trucks, as the name suggests, are transport vehicles with refrigeration capabilities. During transportation, goods are usually placed inside the truck bed, which requires the truck bed to have a certain degree of sealing and strong insulation. This places certain requirements on the truck bed panels that make up the truck bed, and these truck bed panels are usually made by hot pressing to press various materials together.

[0003] When using existing refrigerated truck body panel hot pressing devices, the hot-pressed panels are located between the upper and lower hot pressing plates, which obstructs the material discharge, making it inconvenient to discharge. Furthermore, the panels cannot be limited during hot pressing, causing them to easily deviate from their original position, resulting in poor performance. Therefore, a new hot pressing device for refrigerated truck body panel production is needed to solve this problem. Utility Model Content

[0004] This utility model proposes a hot pressing device for the production of refrigerated truck body panels. Driven by a servo motor, the heating plate automatically completes precise pressing and separation along an L-shaped trajectory. Combined with a spring-buffered baffle, it achieves adaptive limiting, effectively improving the production efficiency and product forming quality of hot pressing of refrigerated truck body panels.

[0005] This utility model is implemented as follows: a hot pressing device for producing refrigerated truck body panels includes a base plate and an upper heating plate. A lower heating plate is provided on the upper end surface of the base plate via a driving mechanism. The driving mechanism includes two support plates fixedly connected to the upper end surface of the base plate. A threaded rod is rotatably connected between the two support plates. A servo motor with its output end fixedly connected to the threaded rod is installed on the outer wall of one of the support plates. A sliding plate is threadedly connected to the outer wall of the threaded rod. Two connecting rods are movably connected to the upper end surface of the sliding plate via hinges. The other ends of the two connecting rods are movably connected to the lower heating plate via hinges. Two symmetrically distributed rollers are rotatably connected to the outer wall of the lower heating plate via a coupling shaft. Two symmetrically distributed side plates are fixedly connected to the upper end surface of the base plate. An L-shaped groove is provided through the outer wall of the side plate to slide with the rollers.

[0006] As a preferred embodiment of the hot pressing device for producing refrigerated truck body panels according to this utility model, the upper end face of the lower heating plate is provided with a U-shaped groove, the inner wall of the U-shaped groove is slidably connected with a U-shaped baffle, and a plurality of evenly distributed springs are fixedly connected between the lower end face of the U-shaped baffle and the bottom end face of the U-shaped groove.

[0007] As a preferred embodiment of the hot pressing device for producing refrigerated truck body panels according to this utility model, the outer wall of the U-shaped baffle is fixedly connected with a plurality of limiting blocks, and the inner wall of the U-shaped groove is provided with a limiting groove that is slidably connected to the limiting blocks.

[0008] As a preferred embodiment of the hot pressing device for producing refrigerated truck body panels according to this utility model, both the lower heating plate and the upper heating plate have cavities inside, the cavities are filled with heat-conducting oil, and the outer walls of both the lower heating plate and the upper heating plate are provided with oil inlets and outlets communicating with the cavities.

[0009] As a preferred embodiment of the hot pressing device for producing refrigerated truck body panels according to this utility model, two limiting rods that are slidably connected to the slide plate are fixedly connected between the two support plates.

[0010] As a preferred embodiment of the hot pressing device for producing refrigerated truck body panels according to this utility model, a controller is provided on the outer wall of one of the side panels, and the servo motor and the controller are electrically connected.

[0011] The beneficial effects of this utility model are:

[0012] 1. Driven by a servo motor, the threaded rod precisely controls the movement of the lower heating plate along a preset L-shaped path, automatically completing the pressing and separation process with the upper heating plate. The panel requires no additional lateral movement or lifting during the entire loading, hot pressing, and unloading process, ensuring smooth and unobstructed discharge. This significantly simplifies operation and improves the automation and efficiency of production.

[0013] 2. The spring-supported U-shaped baffle on the lower heating plate can play a precise limiting role when placing the panel to prevent misalignment. During the pressing process, it is compressed into the U-shaped groove, effectively compensating for the thickness error of the panel, ensuring the stability of the baffle movement, and improving the stability of the hot pressing process and the molding quality of the product.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0020] Please see Figure 1-3 A hot pressing device for producing refrigerated truck body panels includes a base plate 1 and an upper heating plate 12. A lower heating plate 7 is provided on the upper end surface of the base plate 1 via a drive mechanism. The drive mechanism includes two support plates 2 fixedly connected to the upper end surface of the base plate 1. A threaded rod 3 is rotatably connected between the two support plates 2. A servo motor 4 with its output end fixedly connected to the threaded rod 3 is installed on the outer wall of one of the support plates 2. A slide plate 5 is threadedly connected to the outer wall of the threaded rod 3. Two connecting rods 8 are movably connected to the upper end surface of the slide plate 5 via a hinge. The other ends of the two connecting rods 8 are movably connected to the lower heating plate 7 via hinges. Two symmetrically distributed rollers 11 are rotatably connected to the outer wall of the lower heating plate 7 via a coupling. Two symmetrically distributed side plates 9 are fixedly connected to the upper end surface of the base plate 1. An L-shaped groove 10 is slidably connected to the rollers 11 through the outer wall of the side plates 9.

[0021] In this embodiment: the panel to be hot-pressed is placed in the U-shaped baffle 14 on the lower heating plate 7. The servo motor 4 is started, and the servo motor 4 drives the threaded rod 3 to rotate, which in turn drives the slide plate 5 to move to the right along the limit rod 6. The slide plate 5 further drives the lower heating plate 7 to move to the right through the connecting rod 8. At the same time, the slide plate 5 drives the roller 11 to roll on the inner wall of the L-shaped slide groove 10. When the roller 11 moves to the right end of the L-shaped slide groove 10, the slide plate 5 continues to move to the right, which drives the roller 11 to move upward, which in turn drives the lower heating plate 7 to move upward and press against the upper heating plate 12 to hot-press the panel. After the hot pressing is completed, the servo motor 4 drives the threaded rod 3 to rotate in the opposite direction, which in turn drives the lower heating plate 7 to reset. The panel is not obstructed when loading and unloading, which facilitates material discharge.

[0022] As a technical optimization of this utility model, a spiral groove 13 is provided on the upper end surface of the lower heating plate 7, and a spiral baffle 14 is slidably connected to the inner wall of the spiral groove 13. A plurality of evenly distributed springs 15 are fixedly connected between the lower end surface of the spiral baffle 14 and the bottom end surface of the spiral groove 13.

[0023] In this embodiment: the internal dimensions of the U-shaped baffle 14 are the same as those of the panel to be pressed. The panel is placed inside the U-shaped baffle 14 to facilitate the limiting of the panel. When the lower heating plate 7 and the upper heating plate 12 are pressed together, the U-shaped baffle 14 is pressed into the U-shaped groove 13 and the spring 15 is compressed. When the lower heating plate 7 and the upper heating plate 12 are separated, the U-shaped baffle 14 is reset under the elastic force of the spring 15.

[0024] As a technical optimization of this utility model, the outer wall of the herringbone 14 is fixedly connected with a plurality of limiting blocks 16, and the inner wall of the herringbone groove 13 is provided with a limiting groove 17 that is slidably connected to the limiting blocks 16.

[0025] In this embodiment, the limiting block 16 and the limiting groove 17 cooperate to limit the position of the spiral baffle 14 and prevent the spiral baffle 14 from coming out of the spiral groove 13.

[0026] As a technical optimization of this utility model, both the lower heating plate 7 and the upper heating plate 12 have cavities inside, and the cavities are filled with heat-conducting oil. The outer walls of both the lower heating plate 7 and the upper heating plate 12 are provided with oil inlets and oil outlets that communicate with the cavities.

[0027] In this embodiment, the heat transfer oil is easily circulated into the cavity through the oil inlet and outlet, so that the heating plate is maintained at the temperature required for operation.

[0028] As a technical optimization of this utility model, two limiting rods 6 that are slidably connected to the slide plate 5 are fixedly connected between the two support plates 2.

[0029] In this embodiment, the limiting rod 6 facilitates the limiting of the slide plate 5, thereby stabilizing the movement of the slide plate 5.

[0030] As a technical optimization of this utility model, a controller is provided on the outer wall of one of the side plates 9, and the servo motor 4 is electrically connected to the controller.

[0031] In this embodiment, the controller facilitates the normal operation of the servo motor 4.

[0032] The working principle and usage process of this utility model are as follows: First, the plate to be hot-pressed is placed inside the U-shaped baffle 14 on the lower heating plate 7. Then, the servo motor 4 is started, driving the threaded rod 3 to rotate, which in turn drives the slide plate 5 to move to the right along the limiting rod 6. The slide plate 5 further drives the lower heating plate 7 to move to the right via the connecting rod 8. Simultaneously, the slide plate 5 drives the roller 11 to roll on the inner wall of the L-shaped groove 10. When the roller 11 moves to the right end of the L-shaped groove 10, the slide plate 5 continues to move to the right, driving the roller 11... The upward movement causes the lower heating plate 7 to move upward and press against the upper heating plate 12, thus hot-pressing the box panel. When the lower heating plate 7 presses against the upper heating plate 12, the U-shaped baffle 14 is pressed into the U-shaped groove 13 and the spring 15 is compressed. When the lower heating plate 7 separates from the upper heating plate 12, the U-shaped baffle 14 resets under the elastic force of the spring 15. After the hot pressing is completed, the servo motor 4 drives the threaded rod 3 to rotate in the opposite direction, thereby driving the lower heating plate 7 to reset. The box panel is unobstructed during loading and unloading, which facilitates material discharge.
