Description

Technical Field

[0001] The utility model relates to the technical field of rubber dehydration equipment, in particular to an extrusion dehydration device for rubber production. Background Technique

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature, can produce large deformation under very small external forces, and can return to its original state after removing the external forces. Rubber belongs to a completely amorphous polymer. Its glass transition temperature is low, and its molecular weight is often very large, greater than several hundred thousand. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is processed from the gum extracted from plants such as rubber trees and rubber grasses, while synthetic rubber is obtained by polymerization of various monomers.

[0003] In the prior art, there is an extrusion dehydration device for rubber production with the patent publication number of CN211926316U. Through the settings of a box body, a driven roller, a shell, a slider, a first bearing, a second bearing, a threaded shaft, a rotating roller, a third bearing, a motor, a connecting shell, a filter box, activated carbon, and filter cotton, the above patent solves the problems that the existing dehydration device cannot effectively adjust according to the thickness of rubber and cannot filter the discharged water. This device can be adjusted according to the thickness of rubber, is convenient for users to use, and can also filter the discharged water, thus avoiding environmental pollution.

[0004] However, in practice, the power structures at both ends of the driven roller are relatively independent. Therefore, when actually adjusting the distance between the driven roller and the rotating roller, two people need to synchronously rotate the threaded shafts on the shells on both sides of the box body. It is very difficult for two people to ensure that the two threaded shafts rotate at the same speed, and it is easy for the driven roller to be skewed, unable to ensure good horizontalness, so that manual adjustment is required multiple times, wasting manpower. Content of the Utility Model

[0005] To solve the above technical problems, an extrusion dehydration device for rubber production is provided, which solves the problem that when adjusting the distance between the driven roller and the rotating roller in the prior art, two people need to synchronously rotate the threaded shafts on the shells on both sides of the box body. It is very difficult for two people to ensure that the two threaded shafts rotate at the same speed, and it is easy for the driven roller to be skewed, unable to ensure good horizontalness, so that manual adjustment is required multiple times, wasting manpower.

[0006] To achieve the above object, the technical solution adopted by the present utility model is as follows: An extrusion and dehydration device for rubber production, comprising an extrusion box and a water discharge tank fixedly connected to the bottom end of the extrusion box.

Moreover, a rotating roller is tightly sleeved on the rod body of the rotating rod. A lifting rod is slidably arranged above the inner side of the extrusion box, and a lifting rod is tightly sleeved on the rod body of the lifting rod. A driving motor is installed on the outer wall of one side of the extrusion box, and the output shaft of the driving motor rotates and penetrates into the extrusion box and is fixedly connected to one end of the rotating rod. Fixed shells are fixedly connected to both sides of the extrusion box, and a movable block is slidably arranged in each fixed shell. Both ends of the lifting rod penetrate into the two fixed shells respectively and are rotatably connected to the two movable blocks respectively. A pushing and pulling mechanism for synchronously lifting and moving the two movable blocks is arranged on the top of the extrusion box;

[0007] The pushing and pulling mechanism includes a threaded tube vertically rotatably arranged in the middle of the top surface of the extrusion box and a movable plate threadedly connected to the rod body of the threaded tube. Two push rods are vertically fixed to both sides of the bottom surface of the movable plate. The ends of the two push rods are respectively vertically inserted into the two rotating rods and are fixedly connected to the two movable blocks respectively. A fixed ring plate fixedly connected to the top surface of the extrusion box is sleeved on the bottom of the rod body of the threaded tube, and a power component for providing a rotational force for the threaded tube is arranged in the fixed ring plate.

[0008] Preferably, the power component includes a control rod rotatably penetrating through the outer wall of the fixed ring plate. A second bevel gear is tightly sleeved on one end of the control rod located inside the fixed ring plate. A first bevel gear meshing with the second bevel gear is tightly sleeved on the rod body of the threaded tube.

[0009] Preferably, a connecting rod is vertically arranged inside the threaded tube. One end of the connecting rod is vertically and fixedly connected to the top surface of the extrusion box. The other end of the connecting rod vertically penetrates through the threaded tube and is fixed with a connecting disc.

[0010] Preferably, a second corrugated pipe sleeve is sleeved on the rod body of the threaded tube between the movable plate and the fixed ring plate. Both ends of the second corrugated pipe sleeve are fixedly connected to the movable plate and the fixed ring plate respectively.

[0011] Compared with the prior art, the advantages of the present utility model are as follows:

[0012] (1) Through the setting of the push-pull mechanism, the threaded pipe can be easily controlled to rotate, causing the movable plate to move up and down under the threaded structure. In this way, the two movable blocks can move synchronously, at the same speed, and in the same direction by the push-pull rod during the up-and-down movement of the movable plate, thus ensuring that the lifting rod and the lifting roller can be lifted smoothly as a whole and avoiding skew.

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0021] Referring to Figures 1-4As shown in the figure, an extrusion dehydration device for rubber production includes an extrusion box 1 and a water discharge tank 2 fixedly connected to the bottom end of the extrusion box 1. A rotating rod 3 is horizontally arranged below the inner side of the extrusion box 1. The two ends of the rotating rod 3 are respectively rotatably connected to the inner walls on both sides of the extrusion box 1. And a rotating roller 4 is tightly sleeved on the rod body of the rotating rod 3. A lifting rod 6 is slidably arranged above the inner side of the extrusion box 1. A lifting rod 6 is tightly sleeved on the rod body of the lifting rod 6. A driving motor 5 is installed on the outer wall of one side of the extrusion box 1. The output shaft of the driving motor 5 rotates and penetrates into the extrusion box 1 and is fixedly connected to one end of the rotating rod 3;

[0022] During use, first adjust the lifting rod 6 in the inner side of the extrusion box 1 according to the thickness of the rubber in advance, and adjust the distance between the lifting roller 7 and the rotating roller 4 so that the distance between the lifting roller 7 and the rotating roller 4 is consistent with the thickness of the rubber. Then turn on the driving motor 5 to make the rotating rod 3 and the rotating roller 4 rotate as a whole. Immediately afterwards, convey the rubber to be processed between the lifting roller 7 and the rotating roller 4. The lifting roller 7 and the rotating roller 4 cooperate to extrude the rubber, so that the rubber is dehydrated, and the generated liquid can be discharged outwards through the water discharge tank 2.

[0023] Furthermore, referring to Figure 3 As shown in the figure, it is worth noting that fixed shells 8 are fixedly connected and communicated on both sides of the extrusion box 1. An active block 9 is slidably arranged in the fixed shell 8. The two ends of the lifting rod 6 respectively penetrate into the two fixed shells 8 and are respectively rotatably connected to the two active blocks 9. A push-pull mechanism for synchronously lifting and moving the two active blocks 9 is arranged on the top of the extrusion box 1;

[0024] The push-pull mechanism includes a threaded tube 12 vertically rotatably arranged in the middle of the top surface of the extrusion box 1 and a movable plate 10 threadedly connected to the rod body of the threaded tube 12. Two push-pull rods 11 are vertically fixed on both sides of the bottom surface of the movable plate 10. The ends of the two push-pull rods 11 are respectively vertically inserted into the two rotating rods 3 and are respectively fixedly connected to the two active blocks 9;

[0025] Through the setting of the push-pull mechanism, simply control the rotation of the threaded tube 12, and act on the lifting and moving of the movable plate 10 under the threaded structure. In this way, the two active blocks 9 can be synchronously, at the same speed and in the same direction by the push-pull rods 11 during the lifting process of the movable plate 10. Furthermore, when the lifting rod 6 and the lifting roller 7 can be lifted smoothly as a whole, skewing is avoided.

[0026] Furthermore, referring to Figures 1-4 As shown in the figure, it is worth noting that a fixed ring plate 13 fixedly connected to the top surface of the extrusion box 1 is sleeved at the bottom of the rod body of the threaded tube 12. A power component for providing rotational power for the threaded tube 12 is arranged in the fixed ring plate 13;

[0027] The power component includes a control rod 15 rotatably passing through the outer wall of the fixed ring plate 13. At one end of the control rod 15 located inside the fixed ring plate 13, a second bevel gear 16 is tightly sleeved. A first bevel gear 14 meshing with the second bevel gear 16 is tightly sleeved on the rod body of the threaded tube 12.

[0028] Through the setting of the power component, by simply rotating the control rod 15, the second bevel gear 16 can continuously mesh with the first bevel gear 14 inside the fixed ring plate 13, providing rotational force for the threaded tube 12.

[0029] Further, as shown in Figure 1 , Figure 3 and Figure 4 it is worth noting that a connecting rod 17 is vertically arranged inside the threaded tube 12. One end of the connecting rod 17 is perpendicularly and fixedly connected to the top surface of the extrusion box 1. The other end of the connecting rod 17 vertically penetrates upward through the threaded tube 12 and is fixed with a connecting plate 18. A first bellows sleeve 19 is sleeved on the rod body of the threaded tube 12 above the movable plate 10. Both ends of the first bellows sleeve 19 are fixedly connected to the connecting plate 18 and the movable plate 10 respectively;

[0030] A second bellows sleeve 20 is sleeved on the rod body of the threaded tube 12 between the movable plate 10 and the fixed ring plate 13. Both ends of the second bellows sleeve 20 are fixedly connected to the movable plate 10 and the fixed ring plate 13 respectively;

[0031] Through the setting of the second bellows sleeve 20 and the first bellows sleeve 19, when the movable plate 10 moves downward, the movable plate 10 can stretch the first bellows sleeve 19 to deform on one side and compress the second bellows sleeve 20 to deform on the other side. In this way, by utilizing the elastic characteristics of the first bellows sleeve 19 and the second bellows sleeve 20, the flexibility of the movable plate 10 during lifting and lowering is not hindered. Moreover, the first bellows sleeve 19, the second bellows sleeve 20 and the fixed ring plate 13 cooperate with each other to form a protection outside the threaded tube 12, thereby avoiding the direct exposure of the threaded tube 12 to a large amount of dust and impurities and improving the service life of the threaded tube 12.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present utility model.
