Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastics processing, concretely to a polyamide plastic extrudate tensile reinforcement device. BACKGROUND

[0002] In modern industrial production, polyamide plastics are widely used in automobile manufacturing, electronic appliances, aerospace, textiles and many other fields due to their excellent mechanical properties, wear resistance, chemical corrosion resistance and good processing performance. The performance of polyamide plastics is largely dependent on their internal molecular structure and orientation state. After polyamide plastic extrusion, the molecular chains of polyamide plastic can be oriented and arranged along the stretching direction through the stretching reinforcement process, thereby significantly improving the tensile strength, modulus and other mechanical properties. However, in the polyamide plastic extrudate tensile reinforcement device, the traction roller as a key component directly affects the stretching effect. The common traction roller is composed of an outer roller and an inner roller. After a long time of operation, the outer roller is prone to looseness, which destroys the uniformity of the stretching force, and the extrudate is subjected to different forces at different parts, which seriously affects the product quality.

[0003] To solve the above problems, the utility model provides a polyamide plastic extrudate tensile reinforcement device. UTILITY MODEL CONTENTS

[0004] The utility model solves the technical problem of overcoming the defects in the prior art, and provides a polyamide plastic extrudate tensile reinforcement device.

[0005] To solve the above technical problems, the utility model adopts the technical scheme of a polyamide plastic extrudate tensile reinforcement device, which comprises an outer frame and a conveying main body installed on the inner wall of the outer frame. A plurality of stretching assemblies are arranged on the upper end of the conveying main body. Each stretching assembly is provided with a power main body on one side. The stretching assembly comprises an inner roller main body and an outer roller main body arranged on the outer wall of the inner roller main body. One end of the inner roller main body protrudes from the outer roller main body, and the end of the inner roller main body protruding from the outer roller main body is fixedly connected with the output end of the power main body.

[0006] An active channel is formed in the inner part of the inner roller main body. A threaded rod is rotatably connected to the inner wall of the active channel. An active block is threadedly connected to the outer wall of the threaded rod. The outer wall of the active block is slidably connected with the side wall of the active channel. A through opening is formed in the side wall of the inner roller main body. A side mounting block is arranged on the inner wall of the through opening. The outer wall of the side mounting block is fixedly connected with a top block main body.

[0007] Further, one end of the threaded rod penetrates the inner roller main body and the outer roller main body, and a control block is fixedly connected to the end of the threaded rod penetrating the inner roller main body and the outer roller main body. The control block is rotatably connected with the outer wall of the outer roller main body.

[0008] Furthermore, when the movable block and the side mounting block are not on the same horizontal line, the end of the top block body away from the side mounting block is attached to the inner wall of the outer roller body.

[0009] Furthermore, the outer wall of the side-mounted block away from the main body of the top block has an arc-shaped structure, and the side-mounted block is a component made of rubber.

[0010] Furthermore, the side-mounted block has an elastic cavity inside, and a rubber elastic column is fixedly connected to the inner wall of the elastic cavity.

[0011] Furthermore, multiple sets of the rubber elastic columns are provided, and all sets of elastic columns are evenly distributed about the inner wall of the elastic cavity.

[0012] Compared with the prior art, the beneficial effects of this utility model include: the operator can rotate the control block to drive the threaded rod to rotate. When the movable block and the side mounting block are not on the same horizontal line, the end of the top block body away from the side mounting block is tightly attached to the inner wall of the outer roller body, providing initial support for the outer roller. As the threaded rod continues to rotate, the movable block moves in the movable channel until it is on the same horizontal line as the side mounting block, thereby squeezing the side mounting block to deform it. The side mounting block is made of rubber, and its internal elastic cavity and multiple sets of rubber elastic columns play an elastic support role. Through elastic deformation, it provides stable support force to the top block body, pushing the top block body to fit more tightly to the inner wall of the outer roller body. This solves the problem that after long-term operation, the outer roller is prone to loosening, which leads to the destruction of the uniformity of tensile force, uneven force on different parts of the extrudate, and seriously affects product quality.

[0020] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0021] To address the problem that the outer roller easily loosens after prolonged operation, leading to uneven tension and inconsistent stress on different parts of the extrudate, which severely affects product quality, the following preferred technical solution is provided:

[0022] A polyamide plastic extrusion stretching and strengthening device includes an outer frame 1 and a conveying body 2 installed on the inner wall of the outer frame 1, which is responsible for smoothly conveying the polyamide plastic extrusion to the subsequent processing area. Multiple sets of stretching components 3 are arranged at the upper end of the conveying body 2. A power unit 4 is arranged on one side of each set of stretching components 3, providing the power required for the rotation of the stretching components 3. The stretching components 3 include an inner roller body 31 and an outer roller body 32 disposed on the outer wall of the inner roller body 31. One end of the inner roller body 31 protrudes from the outer roller body 32, and the protruding end of the inner roller body 31 is fixedly connected to the output end of the power unit 4. An active channel 33 is provided inside the inner roller body 31 for the active... A threaded rod 34 is rotatably connected to the inner wall of channel 33, and a movable block 36 is threadedly connected to the outer wall of the threaded rod 34. The outer wall of the movable block 36 is slidably connected to the side wall of the movable channel 33. An opening is provided on the side wall of the inner roller body 31, and a side mounting block 37 is provided on the inner wall of the opening. A top block body 38 is fixedly connected to the outer wall of the side mounting block 37. One end of the threaded rod 34 passes through the inner roller body 31 and the outer roller body 32, and a control block 35 is fixedly connected to the end of the threaded rod 34 that passes through the inner roller body 31 and the outer roller body 32. The control block 35 is rotatably connected to the outer wall of the outer roller body 32. When the movable block 36 and the side mounting block 37 are not on the same horizontal line, the end of the top block body 38 away from the side mounting block 37 is attached to the inner wall of the outer roller body 32.

[0023] The outer wall of the side mounting block 37 away from the top block body 38 has an arc-shaped structure. The side mounting block 37 is a component made of rubber. An elastic cavity 39 is opened inside the side mounting block 37. A rubber elastic column 310 is fixedly connected to the inner wall of the elastic cavity 39. Multiple sets of rubber elastic columns 310 are provided, and the multiple sets of elastic columns 310 are evenly distributed about the inner wall of the elastic cavity 39.

[0024] Specifically, in the stretching and strengthening process, the polyamide plastic extrusion is smoothly conveyed to the working area of ​​the stretching assembly 3 via the conveying body 2. The power body 4 is started, and its output end drives the inner roller body 31 to rotate. Since the inner roller body 31 and the outer roller body 32 cooperate with each other, their friction causes the outer roller body 32 to rotate synchronously, thereby applying a stretching force to the polyamide plastic extrusion and achieving the stretching and strengthening treatment.

[0025] If the outer roller becomes loose, the operator can rotate the control block 35 to rotate the threaded rod 34. When the movable block 36 and the side mounting block 37 are not on the same horizontal line, the end of the top block body 38 away from the side mounting block 37 is tightly attached to the inner wall of the outer roller body 32, providing initial support for the outer roller. As the threaded rod 34 continues to rotate, the movable block 36 moves in the movable channel 33 until it is on the same horizontal line as the side mounting block 37, thereby squeezing the side mounting block 37 to deform it. The side mounting block 37 is made of rubber, and its internal elastic cavity 39 and multiple sets of rubber elastic columns 310 play an elastic support role. Through elastic deformation, it provides stable support force to the top block body 38, pushing the top block body 38 to fit more tightly to the inner wall of the outer roller body 32. This solves the problem that after long-term operation, the outer roller is prone to loosening, which leads to the destruction of the uniformity of the tensile force, uneven force on different parts of the extrudate, and seriously affects the product quality.

[0026] In addition, the end of the side block 37 away from the top block body 38 is arc-shaped, which increases the contact area with the inner wall of the outer roller body 32 and improves the support stability. When the device is running, the rubber elastic column 310 can also elastically compensate for the small displacement of the outer roller body 32 caused by the force, which enhances the stability of the outer roller body 32 in the stretching operation from multiple dimensions and ensures the stability and consistency of the stretching strengthening effect.
