Description

Technical Field

[0001] This invention belongs to the technical field of plastic tablet presses, specifically relating to a tablet press for processing plastic sheets. Background Technology

[0002] Plastic is a material with high molecular organic matter as its main component. It has high plasticity and is widely used. In the manufacturing process, plastic is made by combining synthetic resin, fillers, plasticizers, stabilizers, lubricants and colorants, etc., and then undergoing processes such as uniform pressing, heating and melting, stretching and cooling, and cutting and forming.

[0003] A plastic tablet press is a mechanical device used to compress primary plastic granules into sheet or plate-like materials. The uniformity, efficiency, and variety of tablet specifications of a plastic tablet press are closely related to the production efficiency and economic benefits of an enterprise.

[0004] Currently, most plastic tableting machines on the market rely on manual feeding, which is time-consuming and labor-intensive. Existing feeding devices for plastic tableting machines cannot control the flow rate of plastic granules, resulting in reduced tableting uniformity and significantly reduced tableting efficiency. Furthermore, the raw materials may contain impurities or dust, which cannot be detected in time, affecting the quality of the finished product. Summary of the Invention

[0005] The purpose of this invention is to provide a tablet press for processing plastic sheets, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tablet press for processing plastic sheets, comprising a base, a fixing rod, and a feeding box. The fixing rod is fixedly connected to the feeding box. Two feeding box outlets are provided below the feeding box. One end of each feeding box outlet is connected to a conduit. A connecting plate is fitted onto each conduit. The other end of the two conduits is connected to a pipe inlet. The two pipe inlets are respectively connected to a detection pipe and a conveying pipe. One end of a compression spring is connected to the connecting plate. A pushing block is provided inside each detection pipe and conveying pipe. Each detection pipe and conveying pipe is provided with a pipe cover. The pipe cover is connected to the other end of the compression spring.

[0007] Preferably, the front and rear push blocks are respectively connected to one end of telescopic rod one and telescopic rod two, and the other end of telescopic rod one and telescopic rod two are connected to a fixed block. The fixed block is slidably connected to a rotating block. A screw is connected below the rotating block. The screw is connected to a forward and reverse motor. A fixed plate is provided below the rotating block. The fixed plate has a groove in the middle. The screw passes through the groove. The fixed plate is fixed on the base.

[0008] Preferably, one end of the detection pipe is connected to a detection pipe sleeve, the conveying pipe is connected to a conveying pipe sleeve, the outlet of the detection pipe sleeve is connected to a weighing box, and the outlet of the conveying pipe sleeve is connected to the inlet of the plastic tablet press.

[0009] Preferably, the fixing blocks connecting the first and second telescopic rods are symmetrically arranged on the rotating block about the screw, and the detection pipe and the conveying pipe are the same size.

[0010] Preferably, the distance from the left side of the two front and rear push blocks to the end of the detection pipe and the conveying pipe is greater than the distance from the left side of the feed inlet of the two front and rear pipes to the end of the detection pipe and the conveying pipe, respectively.

[0011] Preferably, the forward and reverse rotation angles of the forward and reverse motors are fixed.

[0012] The technical effects and advantages of this invention are as follows: 1. Due to the symmetry of telescopic rod one and telescopic rod two, that is, the rotating block drives telescopic rod one and telescopic rod two to travel the same distance but in opposite directions, it indicates that the weight of the material discharged from the detection pipe and the weight of the material discharged from the conveying pipe are the same. By detecting the weight of the material discharged from the pipe within a certain period of time, the weight of the material discharged into the tablet press from the conveying pipe can be known. If there are impurities or dust, it can be detected by detecting the abnormal weight of the material discharged from the pipe, and the processing can be stopped in time and the raw materials can be processed.

[0013] 2. Since the forward and reverse rotation angles of the motor are fixed, the distance between the push blocks can be changed when the tablet press needs to process different plastic sheets. For example, when processing larger plastic sheets, the telescopic rod is swung to the left to its maximum angle, and then the weight of the raw material is placed into the detection pipe. The telescopic rod is then pulled to move the push block to the left so that it can just fit the raw material. At the same time, the telescopic rod is extended by the corresponding distance, and the position of the rotating block and screw changes accordingly. The material entering from the feeding box in the conveying pipe also changes accordingly. This method is suitable for processing different plastic sheets and has high accuracy.

[0014] 3. When processing the same plastic sheet, since the pushing distance of the pusher block is constant, the amount of raw material entering the tablet press is constant, which improves the stability of the processing. Attached Figure Description

Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] This invention provides, for example Figure 1-5 A plastic sheet processing tablet press, as shown, includes a base 100, a fixing rod 110, and a feeding box 200. The fixing rod 110 is fixed to the feeding box 200. Two feeding box outlets 210 are provided below the feeding box 200. The two feeding box outlets 210 are connected to one end of a conduit 220. A connecting plate 230 is fitted on the two conduits 220. The other end of the two conduits 220 is connected to a pipe inlet 240. The two pipe inlets 240 are respectively connected to a detection pipe 250 and a conveying pipe 260. The connecting plate 230 is connected to one end of a compression spring 270. A push block 440 is provided inside the detection pipe 250 and the conveying pipe 260. Both the detection pipe 250 and the conveying pipe 260 are provided with pipe covers 280. The pipe covers 280 are connected to the other end of the compression spring 270.

[0019] Specifically, the two push blocks 440 are respectively connected to one end of the telescopic rod 400 and the telescopic rod 450. The other end of the telescopic rod 400 and the telescopic rod 450 is connected to the fixing block 410. The fixing block 410 is slidably connected to the rotating block 420. The screw 500 is connected to the bottom of the rotating block 420. The screw 500 is connected to the forward and reverse motor 510. A fixing plate 430 is provided below the rotating block 420. The fixing plate 430 has a groove in the middle. The screw 500 passes through the groove. The fixing plate 430 is fixed on the base 100.

[0020] Specifically, one end of the detection pipe 250 is connected to the detection pipe sleeve 300, the conveying pipe 260 is connected to the conveying pipe sleeve 310, the outlet of the detection pipe sleeve 300 is connected to the weighing box, and the outlet of the conveying pipe sleeve 310 is connected to the feed port of the plastic tablet press.

[0021] Specifically, the fixing block 410 connecting the first telescopic rod 400 and the second telescopic rod 450 is symmetrically arranged on the rotating block 420 about the screw 500, and the detection pipe 250 and the conveying pipe 260 are the same size.

[0022] Specifically, the distance from the left side of the two front and rear push blocks 440 to the end of the detection pipe 250 and the conveying pipe 260 is greater than the distance from the left side of the two front and rear pipe inlets to the end of the detection pipe 250 and the conveying pipe 260, respectively, to prevent material from entering the left side of the push blocks during feeding.

[0023] Specifically, the forward and reverse rotation angles of the forward and reverse motor 510 are fixed.

[0024] Working principle: During operation, when the forward and reverse motor 510 is started, the upper part of the rotating block 420 swings to the right, driving the telescopic rod 400 to move to the right, pushing the block 440 to push the raw material to the right, opening the pipe cover 280, and allowing the raw material in the detection pipe 250 to enter the weighing box for weighing. Subsequently, due to the action of the forward and reverse motor 510, after the material is discharged, the upper part of the rotating block 420 will rotate to the left. At this time, the pipe cover 280, due to the action of the compression spring 270, will close the outlet of the detection pipe 250. When the pushing block 440 travels to the left side of the pipe inlet 240, the raw material enters from the feeding box 200. Similarly, when the detection pipe 250 is fed, the conveying pipe 260 sends the raw material into the tablet press inlet for processing. Because the detection pipe 250 and the conveying pipe... The material discharge volume is the same each time, and the raw materials in the weighing box can be weighed within a certain period of time to detect whether the raw materials contain impurities. If it is necessary to process larger plastic sheets, the telescopic rod 400 is swung to the left to the maximum angle by the forward and reverse motor 510. Then, the weight of the raw material is placed into the detection pipe 250, and the telescopic rod 400 is pulled to move the push block 440 to the left so that it can just fit the raw material. At the same time, the telescopic rod 400 is extended by a corresponding distance, and the position of the rotating block 420 and the screw 500 changes accordingly. The distance of the telescopic rod 450 in the conveying pipe 260 also changes accordingly, so the material fed into the feeding box 200 also changes accordingly. The same principle applies when processing smaller plastic sheets. This invention is applicable to the processing of different plastic sheets and has high accuracy.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
