Description

Technical Field

[0001] This utility model relates to the technical field of pressure roller devices, specifically a pressure roller device for a powder coating twin-screw extrusion tablet press. Background Technology

[0002] A twin-screw extruder for powder coating typically consists of a feeding device, a screw, and a barrel. The feeding device is responsible for stably conveying the powder coating raw materials into the barrel. The screw rotates in the same direction within the barrel. Through the precise cooperation between the screw and the barrel, the material is conveyed, compacted, and plasticized. The screw design includes a combination of threaded blocks and mixing blocks, which can be optimized according to different production process requirements to meet the mixing needs of different powder coating formulations.

[0003] Currently, after a period of use, tablet presses often require the screw to be removed for cleaning. However, the screw is generally quite long, and during the process of pulling it out of the screw barrel, its surface slides against the inner wall of the barrel, causing structural damage to the screw surface and affecting subsequent use. Therefore, a new type of pressure roller device for a powder coating twin-screw extrusion tablet press is needed to solve the above problems. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0024] This embodiment provides a pressure roller device for a twin-screw extrusion tablet press for powder coatings. It primarily addresses the problem that after a period of use, tablet presses often require the screw to be removed for cleaning. However, the screw is typically quite long, and during the process of pulling it out of the barrel, its surface slides against the inner wall of the barrel, causing structural damage and affecting subsequent use. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-5 Please provide a detailed explanation:

[0025] A pressure roller device for a twin-screw extruder tablet press for powder coatings includes: a placement frame 1, two mounting rings 2, and a screw barrel 3 fixedly mounted on the top of the placement frame 1. Two screws 5 are rotatably inserted into the inner wall of the screw barrel 3. During use, the user adds material through a feeding port 4 located at the top of the screw barrel 3. A drive unit 8 drives the two screws 5 to rotate, thus processing the material inside the screw barrel 3. Regarding the rotatable mounting method of the two screws 5 on the inner wall of the screw barrel 3, this device uses an interference fit bearing 6 at both ends of each screw 5. It also includes two... Mounting rings 2 are fixedly fitted onto the outer rings of several bearings 6. In use, the user inserts one mounting ring 2 and two screws 5 sequentially into the inner wall of the screw cylinder 3, so that the surface of the other mounting ring 2 abuts against the opening of the screw cylinder 3. Finally, the mounting unit 7 installs both mounting rings 2 onto the surface of the screws 5, completing the operation. The main components of the mounting unit 7 are: a mounting edge 71 on the surface of the screw cylinder 3 and several mounting bolts 72. In use, the user threads several of the mounting bolts 72. Insert one end of the screw cylinder 3 so that the surfaces of the mounting bolts 72 are threaded into the surface of one of the mounting rings 2. Then, insert several other mounting bolts 72 into the surface of another mounting ring 2 and then into the surface of the mounting edge 71. This achieves the installation of the two mounting rings 2 on the surface of the screw cylinder 3. The main components of the drive unit 8 are: two drive wheels 81. One end of one drive wheel 81 is fixedly installed on one end of one of the screws 5, and the other end of the drive wheel 81 is fixedly installed on the output end of the drive motor 83, which is fixedly installed on the surface of the screw cylinder 3. In use, the user connects the other end of the other drive wheel 81 to the surface of the other screw 5 through the connecting unit 85. By controlling the output end of the drive motor 83 to rotate through the controller 84 fixedly installed on the surface of the mounting bracket 1, one of the drive wheels 81 can be driven to rotate. At the same time, the drive belt 82, which is slidably sleeved on the surface of the two drive wheels 81, drives the two drive wheels 81 and the two screws 5 simultaneously. It should be noted that the bearing 6 has an outer ring and an inner ring. When the outer ring is fixed, the inner ring can rotate independently.

[0026] By fixing a screw barrel 3 to the top of the placement frame 1, and providing a feeding port 4 at the top of the screw barrel 3, the user pours the material into the feeding port 4 during use. The two screws 5 are driven to rotate by the drive unit 8, thus processing the material. After a period of use, the user first removes the two mounting rings 2 from the surface of the screw barrel 3 by using the installation unit 7, pulls one of the mounting rings 2, and causes the other mounting ring 2 to slide on the inner wall of the screw barrel 3. Finally, the two screws 5 are removed, thus preventing the two screws 5 from sliding on the inner wall of the screw barrel 3 and causing damage to the surface of the screws 5.

[0027] By setting a movable frame 9 on one side of the placement frame 1 and a placement ring 11 above the movable frame 9, the user controls the hydraulic rod 10 to extend and retract via the controller 84, causing the placement ring 11 to descend. Then, the user pulls the movable frame 9 so that the placement ring 11 is positioned below one of the mounting rings 2. Finally, the user controls the hydraulic rod 10 to extend and retract via the controller 84, causing the limiting groove 12 on the surface of the placement ring 11 to fit onto the surface of one of the mounting rings 2, thus supporting the mounting ring 2. Subsequently, the user pulls the movable frame 9, which allows the two screws 5 to slide smoothly out from the inner wall of the screw barrel 3, facilitating the user's operation.

[0028] like Figure 4 As shown, in some embodiments, the main components of the connecting unit 85 are: a plug 852 fixedly installed at one end of another transmission wheel 81, and an mounting block 851 fixedly installed at one end of the screw 5. In use, the user inserts the screw 5 into the inner wall of the screw barrel 3 and simultaneously inserts the plug 852 into the inner wall of the mounting block 851. The position of the plug 852 is then limited by the limiting unit 853, thereby achieving the connection between one end of one transmission wheel 81 and one end of one screw 5. The main component of the limiting unit 853 is a plug rod 8531. In use, the user slides the plug rod 8531 into the surface of the mounting block 851 and then into the surface of the plug 852. Finally, the user threadedly fits the abutment nut 8532 onto the surface of the plug rod 8531, thereby limiting the position of the plug 852 on the inner wall of the mounting block 851.

[0029] like Figure 1As shown, in some embodiments, a movable frame 9 and a hydraulic rod 10 are provided at one end of the placement frame 1. A placement ring 11 is provided above the movable frame 9, and the two ends of the hydraulic rod 10 are respectively fixedly installed on the surfaces of the movable frame 9 and the placement ring 11. When the user needs to pull the mounting ring 2, the hydraulic rod 10 can be controlled by the controller 84 to adjust the spatial height of the placement ring 11. Finally, the surface of one of the mounting rings 2 is placed on the inner wall of the limiting groove 12 on the surface of the placement ring 11. Finally, the movable frame 9 is pulled to move the placement ring 11 and the screw 5 away from it. At the same time, during the movement, the guide plate 13 fixedly installed on the surface of the movable frame 9 will slide on the inner wall of the placement frame 1 to ensure the stability of the movable frame 9 during the movement.

[0030] The working process of this utility model is as follows:

[0031] First, the user needs to pour the material into the inner wall of the feeding port 4. The controller 84 controls the output end of the drive motor 83 to rotate, which will drive the two screws 5 to rotate and realize the processing of the material.

[0032] Secondly, when the screw 5 needs to be cleaned and replaced after a period of processing, the user needs to control the hydraulic rod 10 to extend and retract through the controller 84, drive the moving frame 9 to rise and fall, so that the mounting ring 2 is inserted into the inner wall of the limit groove 12, and then pull the moving frame 9 to easily pull the two screws 5.

[0033] 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.
