Description

Technical Field

[0001] This utility model relates to the field of rubber strip processing technology, and in particular to a rubber strip traction device for modified plastic production. Background Technology

[0002] In the large-scale production of modified plastic strips (such as sealing strips and functional profile strips), the core process is "raw material mixing, extrusion by extruder, strip shaping, subsequent cutting, and winding, while the traction equipment is the key intermediate equipment connecting extrusion molding and downstream processing."

[0003] Considering that the modified plastic strips molten and extruded by the extruder are still in a high-temperature softened state when they leave the extrusion die, if they are directly guided into the traction device through the front guide assembly of the equipment at this time, the strips are prone to problems such as not being able to stably embed into the clamping area of ​​the traction roller or undergoing irreversible deformation due to the pressure of the traction roller at the moment of contact. This makes it difficult for the traction device to form an effective and stable connection and traction cooperation with the strips. Therefore, a strip traction device for the production of modified plastics is proposed. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the existing technology that when the rubber strip is still in a high-temperature softened state after leaving the extrusion mold, it is easy for it to be unable to be stably embedded in the clamping area of ​​the traction roller or to undergo irreversible deformation due to the pressure of the traction roller at the moment of contact. Therefore, this invention proposes a rubber strip traction device for the production of modified plastics.

[0005] To address the problems existing in the prior art, the present invention adopts the following technical solution:

[0006] A traction device for producing rubber strips from modified plastics includes a main frame, inside which are two tension regulating and cooling components, and on the top of the main frame is a traction component.

[0007] The tension regulating cooling assembly includes a cold water tank fixedly connected inside the main frame. A first rotating block is provided in the inner cavity of the cold water tank, and the first rotating block can move in a direction perpendicular to the bottom of the cold water tank.

[0008] Preferably, an electric telescopic rod is fixedly connected to the top of the main frame, a connecting rod is fixedly connected to the output end of the electric telescopic rod, a sleeve is fixedly connected to the surface of the connecting rod, and the surface of the sleeve is fixedly connected to the first rotating block.

[0009] Preferably, the cold water tanks of the two sets of tension regulating cooling components are arranged alternately back and forth along the conveying direction of the rubber strip.

[0010] Preferably, the traction assembly includes a support frame fixedly connected to the bottom of the inner cavity of the main frame, a roller rotatably connected inside the support frame, and a second rotating block fixedly connected to the surface of the roller.

[0011] Preferably, the second rotating block and the first rotating blocks of the two sets of tension regulating and cooling assemblies are arranged collinearly along the rubber strip conveying direction.

[0012] Preferably, a drive motor is fixedly connected to the surface of the main frame, and the output end of the drive motor passes through the support frame and is fixedly connected to the end of the second rotating block.

[0013] Preferably, a wear-resistant rubber layer is fixedly connected to the outer wall of the first rotating block, and the surface of the wear-resistant rubber layer is provided with anti-slip texture.

[0014] Preferably, an inlet pipe is fixedly connected to one side of the cold water tank, and an outlet pipe is fixedly connected to the other side of the cold water tank. Both the inlet and outlet pipes are equipped with flow control valves.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: In the modified plastic strip traction device, the first rotating block drives the strip to be immersed in the cooling liquid of the cold water tank for cooling and shaping, so that the strip hardens. At the same time, the tension is adjusted to keep the strip straight, so as to avoid clamping failure due to irregular shape when it enters the traction component. This ensures that the traction component can stably grab the strip and transport it along the preset path. Considering that if the tension of the strip is uneven before entering the traction component, the traction force of the traction component will easily aggravate the deformation of the strip. The first rotating block adjusts the tension synchronously during the cooling process, so that the strip enters the traction component with uniform tension, avoiding local stretching or wrinkling of the strip due to sudden tension changes during traction.

[0027] Example: This example provides a rubber strip traction device for the production of modified plastics. See [link to example]. Figure 1-4 Specifically, it includes a main frame 1, inside which are two tension adjustment and cooling components 2, and on the top of the main frame 1 is a traction component 3;

[0028] The tension regulating cooling assembly 2 includes a cold water tank 21 fixedly connected inside the main frame 1. A first rotating block 230 is provided in the inner cavity of the cold water tank 21. The first rotating block 230 can move in a direction perpendicular to the bottom of the cold water tank 21.

[0029] In this optional embodiment, coolant of a preset level is first injected into the inner cavity of the cold water tank 21 of the tension regulating cooling assembly 2. The rubber strip is pulled by the traction assembly 3. When the rubber strip enters the inner cavity area of ​​the cold water tank 21, the first rotating block 230 moves downward in a direction perpendicular to the bottom of the cold water tank 21 until it contacts the surface of the rubber strip and applies a preset pressure. During this process, the first rotating block 230 adjusts the conveying tension of the rubber strip by contacting and cooperating with the rubber strip, and drives the rubber strip to move towards the coolant in the inner cavity of the cold water tank 21, so that the rubber strip is partially or completely immersed in the coolant, and cooling and shaping are achieved through heat exchange.

[0030] Optionally, an electric telescopic rod 22 is fixedly connected to the top inside the main frame 1, a connecting rod 220 is fixedly connected to the output end of the electric telescopic rod 22, a sleeve 23 is fixedly connected to the surface of the connecting rod 220, and the surface of the sleeve 23 is fixedly connected to the first rotating block 230.

[0031] In this optional embodiment, the electric telescopic rod 22 is initially in a retracted state, driving the sleeve 23 and the first rotating block 230 fixedly connected to it to remain in the initial position above the inner cavity of the cold water tank 21, ensuring that the rubber strip does not directly contact the coolant when it enters; after the traction component 3 is started, the electric telescopic rod 22 works and drives the connecting rod 220 to move downward, driving the first rotating block 230 fixed on the surface of the sleeve 23 to move downward in a direction perpendicular to the bottom of the cold water tank 21 until the first rotating block 230 contacts the surface of the rubber strip and applies pressure. During this process, the first rotating block 230 adjusts the conveying tension of the rubber strip by contacting and cooperating with the rubber strip, and drives the rubber strip to move towards the coolant in the inner cavity of the cold water tank 21, so that the rubber strip is partially or completely immersed in the coolant, and cooling and shaping are achieved through heat exchange;

[0032] Optionally, the cold water tanks 21 of the two sets of tension regulating cooling components 2 are arranged alternately back and forth along the conveying direction of the rubber strip;

[0033] In this optional embodiment, the electric telescopic rods 22 of the two sets of tension-adjustable cooling components 2 can be independently controlled to achieve the alternating driving of the rubber strips by the two sets of first rotating blocks 230 to contact the coolant in the corresponding cold water tank 21 cavity.

[0034] Optionally, the traction assembly 3 includes a support frame 32 fixedly connected to the bottom of the inner cavity of the main frame 1, a roller 320 rotatably connected inside the support frame 32, and a second rotating block 33 fixedly connected to the surface of the roller 320.

[0035] In this optional embodiment, the rotation of the roller 320, which is rotatably connected inside the support frame 32, drives the second rotating block 33, which is fixed on its surface, to rotate synchronously. The second rotating block 33 generates traction force through friction with the surface of the rubber strip, which, together with the supporting effect of the roller 320, enables the winding device to wind up the rubber strip.

[0036] Optionally, the second rotating block 33 and the first rotating block 230 of the two sets of tension regulating and cooling assemblies 2 are arranged collinearly along the rubber strip conveying direction;

[0037] In this optional embodiment, the second rotating block 33 and the first rotating block 230 of the two sets of tension adjustment and cooling components 2 are arranged collinearly along the conveying direction of the rubber strip. This ensures that the rubber strip always moves in a straight line during the conveying process, avoids uneven force on the rubber strip due to path deviation, and prevents stretching deformation or twisting, thus ensuring the shape and dimensional accuracy of the rubber strip.

[0038] Optionally, a drive motor 31 is fixedly connected to the surface of the main frame 1, and the output end of the drive motor 31 passes through the support frame 32 and is fixedly connected to the end of the second rotating block 33.

[0039] In this optional embodiment, the operation of the drive motor 31 can drive the roller 320 inside the support frame 32 to rotate, thereby providing driving force for the rubber strip;

[0040] Optionally, a wear-resistant rubber layer is fixedly connected to the outer wall of the first rotating block 230, and the surface of the wear-resistant rubber layer is provided with anti-slip texture;

[0041] In this optional embodiment, a wear-resistant rubber layer is fixed to the outer wall of the first rotating block 230 and anti-slip texture is provided on the surface. This can enhance the friction with the rubber strip, prevent the rubber strip from slipping during traction, and ensure the stability and accuracy of conveying. The wear-resistant rubber layer can reduce the direct wear between the first rotating block and the rubber strip, extend the service life of both, and the rubber material has a certain elasticity, which can buffer the pressure of the first rotating block on the rubber strip, prevent the rubber strip from being damaged, and protect the product quality.

[0042] Optionally, an inlet pipe is fixedly connected to one side of the cold water tank 21, and an outlet pipe is fixedly connected to the other side of the cold water tank 21. Both the inlet pipe and the outlet pipe are equipped with flow control valves.

[0043] In this optional embodiment, the use of inlet and outlet pipes can achieve cold water circulation, continuously replenishing the cold water tank with low-temperature water, promptly removing heat from the rubber strip, ensuring stable cooling effect, and the flow control valve can precisely adjust the inlet and outlet water flow, and adjust the cooling intensity according to the rubber strip material, production speed, etc., to avoid insufficient or excessive cooling. By controlling the flow, water resources can also be saved, unnecessary waste can be avoided, and production energy consumption can be reduced.

[0044] 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.
