Description

Technical Field

[0001] This utility model relates to the technical field of rubber and plastic material processing equipment, and in particular to a rubber and plastic reinforcing material molding device. Background Technology

[0002] In the production and processing of rubber and plastic reinforcing materials, extrusion molding is one of the key processes. Its core lies in shaping the material by extrusion rollers to meet the dimensional and performance requirements for subsequent use. In existing rubber and plastic reinforcing material molding equipment, the spacing of the extrusion rollers is mostly adjusted manually on one side or by independent drive, which presents the following problems.

[0003] 1. Poor synchronization of spacing adjustment and inconsistent adjustment speed of the two extrusion rollers can easily lead to uneven material stress, resulting in problems such as molding size deviation and edge cracking. 2. Insufficient adaptability of the drive mechanism. When the gap between the extrusion rollers is adjusted, the drive components (such as gears and drive shafts) are prone to disengagement or increased transmission clearance, resulting in unstable extrusion roller speed and further affecting the material forming quality. 3. The operation is complex. Some parts require multiple manual calibrations of the position of the extrusion rollers and the matching relationship of the drive components, which is time-consuming and not conducive to mass production. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a molding device for rubber and plastic reinforcing materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A molding device for rubber and plastic reinforcing materials includes a fixed plate with a through groove at its center. Two symmetrically arranged sliding grooves are formed on the upper surfaces of the fixed plate on both sides of the through groove. A slider is slidably connected to each of the two sliding grooves. A movable plate is fixedly connected to the upper end of each of the two sliders. A groove is formed at one opposite end of each of the two movable plates. An extrusion roller is rotatably connected between the inner walls of both ends of each groove. An adjustment mechanism for adjusting the distance between the two extrusion rollers is provided in each of the two sliding grooves. The adjustment mechanism includes an electric push rod fixedly connected to the inner wall of the sliding groove, with its telescopic end fixedly connected to the side wall of the slider. A drive mechanism for driving the two extrusion rollers is provided on the fixed plate.

[0006] Preferably, the two electric actuators are controlled by a synchronization controller.

[0007] Preferably, the driving mechanism includes two symmetrically arranged fixing blocks fixedly connected to the upper end of the fixing plate, and a key shaft is rotatably connected between the two fixing blocks.

[0008] Preferably, the central shafts of both extrusion rollers pass through the sidewall of the moving plate and are rotatably connected to it, and a first bevel gear is fixedly sleeved at one end of each of the two central shafts passing through the sidewall of the moving plate. A connecting block is fixedly connected to the sidewall of each of the two moving plates, and a through hole is opened on each of the two connecting blocks. A second bevel gear that meshes with the first bevel gear is rotatably connected to each of the two connecting blocks, and the second bevel gear is coaxial with the through hole.

[0009] Preferably, a keyway is provided at the center of the second bevel gear, and the key shaft passes through the keyway and is slidably connected to it.

[0010] Preferably, a motor is fixedly connected to the side wall of one of the fixing blocks.

[0011] Compared with the prior art, the advantages of this utility model are as follows: 1. By controlling the synchronous extension and retraction of two electric push rods through a synchronous controller, two sliders can be driven to slide synchronously along the chute, thereby realizing the synchronous adjustment of the distance between the two extrusion rollers. This effectively avoids the problem of uneven material force caused by asynchronous adjustment and improves the accuracy of molding dimensions.

[0012] 2. The keyway of the key shaft and the second bevel gear adopts a sliding connection structure. During the adjustment of the gap between the extrusion rollers, the second bevel gear can slide along the key shaft while maintaining synchronous rotation with the key shaft. The second bevel gear is always meshed with the first bevel gear, ensuring that the drive mechanism does not disengage and the transmission is stable during the adjustment process.

[0013] 3. Convenient operation and high efficiency: Automatic adjustment is achieved through electric push rods and synchronous controllers, eliminating the need for manual calibration and reducing operational complexity; the motor provides stable power to ensure uniform speed of the extrusion rollers, improving the molding efficiency and quality of rubber and plastic reinforcing materials.

[0016] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] Reference Figure 1-6 A molding device for rubber and plastic reinforcing materials includes a fixed plate 1, which is a horizontally arranged rectangular metal plate with a through groove 9 at its center for the rubber and plastic reinforcing material to pass through during molding. On the upper surfaces of the fixed plate 1 located on the left and right sides of the through groove 9, two symmetrical sliding grooves 3 extending along the length of the fixed plate 1 are provided. The openings of the two sliding grooves 3 face upwards, and each groove is slidably connected to a slider 10 adapted to the sliding groove 3. The upper surfaces of the two sliders 10 are each fixedly connected to a vertically arranged movable plate 6 by bolts. On the opposite side of the two movable plates 6 (i.e., the side closer to the through groove 9), a groove 7 is provided. The extension direction of the groove 7 is consistent with the extension direction of the through groove 9. An extrusion roller is rotatably connected between the inner walls of the two ends of the groove 7 via bearings. The outer wall of the extrusion roller is made of wear-resistant rubber material, used to directly contact the rubber and plastic reinforcing material and achieve extrusion molding. To achieve synchronous adjustment of the gap between the extrusion rollers, an adjustment mechanism is provided in each of the two chutes 3. The adjustment mechanism includes an electric push rod 2 that is fixedly connected to the inner wall of the chute 3 away from the through groove 9 by bolts. The telescopic end of the electric push rod 2 extends along the length of the chute 3, and its end is fixedly connected to the side wall of the slider 10 away from the through groove 9 by a flange. The two electric push rods 2 are electrically connected by a synchronous controller (not shown in the figure). The synchronous controller can control the telescopic speed and telescopic amount of the two electric push rods 2 to be completely consistent, thereby driving the two sliders 10 to slide synchronously along the chute 3, and finally achieving synchronous adjustment of the gap between the two extrusion rollers. To achieve stable driving of the extrusion rollers, a driving mechanism is also provided on the fixed plate 1, as follows: The driving mechanism includes two symmetrically arranged fixed blocks 4 bolted to the upper end face of the fixed plate 1. The two fixed blocks 4 are located on the outer sides of the two moving plates 6, and a key shaft 13 is rotatably connected between the two fixed blocks 4 via a bearing. The central shafts of the two extrusion rollers pass horizontally through the side wall of the moving plate 6 and are rotatably connected to the moving plate 6 via bearings. The ends of the two central shafts passing through the side wall of the moving plate 6 (the ends away from the through groove 9) are both fixedly sleeved with a first bevel gear 11 via a flat key. Horizontally arranged connecting blocks 8 are bolted to the side walls of the two moving plates 6 away from the through groove 9. The connecting blocks 8 have vertically penetrating openings. A through hole 14 is provided, and a second bevel gear 12 is rotatably connected to the connecting block 8 via a bearing. The second bevel gear 12 meshes with the first bevel gear 11, and the axis of the second bevel gear 12 is coaxial with the axis of the through hole 14. A keyway 15 adapted to the key shaft 13 is provided at the center of the second bevel gear 12. The key shaft 13 passes through the through hole 14 and extends into the keyway 15, and is slidably connected to the keyway 15 (that is, the key shaft 13 can drive the second bevel gear 12 to rotate synchronously, and the second bevel gear 12 can slide along the axis of the key shaft 13). A motor 5 is fixedly connected to the outer wall of one of the fixing blocks 4 via bolts. The output shaft of the motor 5 is fixedly connected to one end of the key shaft 13 via a coupling, which is used to provide power for the rotation of the key shaft 13.

[0018] When this utility model is used, according to the thickness requirements of the rubber and plastic reinforcing material to be processed, the extension and retraction amount of the electric push rod 2 is set by the synchronous controller. The synchronous controller controls the synchronous extension and retraction of the two electric push rods 2, which drives the slider 10 to slide along the slide groove 3, thereby adjusting the distance between the two extrusion rollers until the preset size is reached. The motor 5 is started, and the motor 5 drives the key shaft 13 to rotate. The key shaft 13 drives the second bevel gear 12 to rotate synchronously through the keyway 15. The second bevel gear 12 drives the first bevel gear 11 meshing with it to rotate, thereby driving the extrusion roller to rotate. One end of the rubber and plastic reinforcing material is fed from above the through groove 9 of the fixed plate 1 into the space between the two extrusion rollers. The rotating extrusion roller extrudes and shapes the material, and the shaped material is output from below the through groove 9. If different specifications of materials need to be changed, the distance between the extrusion rollers can be quickly adjusted by simply adjusting the electric push rod 2 through the synchronous controller. There is no need to disassemble the drive assembly, making the operation convenient.

[0019] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
