Description

Technical Field

[0001] The present application relates to the technical field of rubber production, and in particular to a rubber production screening mechanism. Background Art

[0002] During the production process of rubber, its raw materials may be mixed with impurities, such as foreign matter, particles or other impurities, which may affect the quality and performance of rubber products. These impurities can be effectively removed through screening to ensure the purity of the raw materials.

[0003] Currently, rubber raw materials are mostly screened by passing them through an inclined filter screen. Under the action of gravity, the rubber raw materials are screened on the surface of the filter screen. However, the speed of the raw materials moving down through the filter screen is relatively fast, which can easily lead to the filtration process being too fast and ineffective screening. Utility Model Content

[0004] In view of this, the purpose of the utility model is to solve the shortcomings existing in the background technology and to propose a rubber production screening mechanism to solve the problems existing in the prior art.

[0006] Preferably, the driving mechanism comprises a motor fixedly mounted on a device frame, the output end of the motor is fixedly connected to a driving shaft, and the end of the driving shaft away from the motor is fixedly connected to a driving wheel, so that the screening frame can be rocked back and forth through the driving mechanism.

[0007] Preferably, the outer surface of the driving wheel is slidably connected to a conveyor belt, and the inner end of the conveyor belt away from the driving wheel is slidably connected to a driven wheel.

[0008] Preferably, a support platform is fixedly connected to the top of the device frame, a rotating shaft is rotatably connected to the inner surface of the support platform, and an outer surface of the rotating shaft is fixedly connected to the inner surface of the driven wheel.

[0009] Preferably, one end of the rotating shaft is fixedly connected to an end plate, and one end of the end plate away from the rotating shaft is rotatably connected to a first shaft, and the end plate can drive the deflection strip via the first shaft during rotation.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The rubber production screening mechanism uses a driving mechanism and a spring to elastically support the screening frame, so that the rubber raw materials are more fully dispersed and mixed in the screening frame. At the same time, the rubber raw materials can be more evenly distributed during the screening process. With the control of the motor and the transmission device, the back and forth pulling speed of the screening frame can be accurately adjusted, avoiding the problem of excessive speed when the raw materials pass through the screening process, ensuring that the screening process is slower and more effective, and improving the screening efficiency and screening accuracy.

[0013] 2. The rubber production screening mechanism, the back and forth movement of the material rake can make the rubber material in the screening frame more evenly distributed, avoiding the formation of material clumps. The movement of the material rake promotes the interaction and mixing between materials, improving the screening effect and screening uniformity. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Through the above technical solution, when the device is in use, the rubber raw material is put into the screening frame 3, and the screening frame 3 can be shaken back and forth through the driving mechanism. In combination with the elastic support of the spring 2 on the screening frame 3, the rubber raw material can be shaken and screened, and the screened raw material slides down and is collected through the guide plate 4.

[0021] Specifically, the driving mechanism includes a motor 5 fixedly mounted on the device frame 1 , an output end of the motor 5 is fixedly connected to a driving shaft 6 , and an end of the driving shaft 6 away from the motor 5 is fixedly connected to a driving wheel 7 .

[0022] Through the above technical solution, the motor 5 can drive the driving wheel 7 to rotate through the driving shaft 6 after being turned on. During the rotation process, the driving wheel 7 can drive the driven wheel 9 to rotate through the tight conveyor belt 8.

[0023] Specifically, the outer surface of the driving wheel 7 is slidably connected to the conveyor belt 8 , and the inner end of the conveyor belt 8 away from the driving wheel 7 is slidably connected to the driven wheel 9 .

[0024] Through the above technical solution, the driven wheel 9 will be linked with the rotating shaft 11 at the axis to rotate synchronously during the rotation process.

[0025] Specifically, a support platform 10 is fixedly connected to the top of the device frame 1 , a rotating shaft 11 is rotatably connected to the inner surface of the support platform 10 , and an outer surface of the rotating shaft 11 is fixedly connected to the inner surface of the driven wheel 9 .

[0026] Through the above technical solution, the two groups of support platforms 10 support the rotating shaft 11 and the driven wheel 9. When the driven wheel 9 rotates, the end plate 12 at the end thereof will rotate synchronously.

[0027] Specifically, one end of the rotating shaft 11 is fixedly connected to an end plate 12 , and one end of the end plate 12 away from the rotating shaft 11 is rotatably connected to a first shaft 13 .

[0028] Through the above technical solution, the end plate 12 will make a circular motion with the rotating shaft 11 as the center when rotating with the rotating shaft 11.

[0029] Specifically, the outer surface of the first shaft 13 is rotatably connected with the deflection bar 14 , the inner side of the screening frame 3 is fixedly penetrated with the second shaft 15 , and the outer surface of the second shaft 15 is rotatably connected with one end of the deflection bar 14 away from the first shaft 13 .

[0030] Through the above technical solution, the end plate 12 can deflect the deflection strip 14 through the first shaft 13 during the circular motion.

[0031] Working principle: When the device is in use, first put the rubber raw material into the screening frame 3, then turn on the motor 5 to drive the driving shaft 6 to rotate. During this process, the driving wheel 7 will rotate synchronously with the driving shaft 6, and then the driven wheel 9 will rotate through the conveyor belt 8, and the rotating shaft 11 will rotate with the rotation of the driven wheel 9. At this time, the end plate 12 at the end of the rotating shaft 11 will make a circular motion. When the end plate 12 moves in a circle, one end of the deflection bar 14 will rotate along the first axis 13, and the other end will rotate along the second axis 15. The entire deflection bar 14 will deflect back and forth, so that the screening frame 3 is pulled back and forth through the deflection bar 14, and the rubber raw materials are more fully dispersed and mixed in the screening frame 3, thereby improving the screening efficiency and screening accuracy. With the elastic support of the spring 2 on the screening frame 3, it can effectively perform the rubber material during the back and forth shaking process. The rubber material screened out can fall on the guide plate 4 and slide down for unified collection during the whole screening process. During the whole screening process, the back and forth swinging of the screening frame 3 enables the rubber raw material to be more evenly distributed during the screening process, reduces the stratification phenomenon, and ensures the uniformity and consistency of the screening results. Meanwhile, during the back and forth swinging of the screening frame 3 to screen the rubber material, the dividing rake 17 can move the material in the screening frame 3 back and forth. The back and forth movement of the dividing rake 17 can make the rubber material in the screening frame 3 be more evenly distributed, and avoid the formation of material clumps. The moving action of the dividing rake 17 promotes the interaction and mixing between the materials, helps to disperse the larger materials into smaller particles, can effectively prevent the accumulation of materials in the sieve holes, reduces the blockage of the sieve holes, keeps the screening smooth, and thus improves the screening effect and screening uniformity.
