Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic pipe body forming, specifically to a pipe drawing machine with a guide mechanism. BACKGROUND

[0002] Plastic pipe extrusion forming technology has been widely used in the field of plastic product production, and the extruded plastic pipe body often needs to enter different subsequent processes according to different production needs or customization requirements, for example, a part of the plastic pipe body needs to enter the printing process for surface pattern processing, and another part only needs to be simply cut.

[0003] However, the pipe drawing part of the current extruder mostly adopts a single-direction straight-line traction method, so that the extruded plastic pipe body can only move in a fixed direction, and secondly, even if it needs to turn, it needs to be reinstalled with a turning device according to the turning direction, therefore, it lacks flexible and convenient adjustment function of the traction path, cannot flexibly adjust the traction direction of the pipe body according to the accurate position of different processes, and is difficult to meet various processing needs. UTILITY MODEL CONTENTS

[0004] The utility model provides a pipe drawing machine with a guide mechanism to solve the problem that the pipe drawing part of the current extruder mostly adopts a single-direction straight-line traction method, so that the extruded plastic pipe body can only move in a fixed direction, and secondly, even if it needs to turn, it needs to be reinstalled with a turning device according to the turning direction, therefore, it lacks flexible and convenient adjustment function of the traction path, and is difficult to meet various processing needs.

[0005] The technical scheme for solving the above technical problems is as follows: a pipe drawing machine with a guide mechanism, comprising:

[0006] A machine table;

[0007] An extruder body arranged on the machine table;

[0008] A cooling assembly arranged on one side of the extruder body for cooling the extruded plastic pipe body;

[0009] A pipe drawing assembly, which comprises a dragging part for dragging the plastic pipe body away from the extruder body and a guide part for adjusting the dragging direction, the dragging part is located on one side of the cooling assembly and arranged on the machine table, wherein the guide part comprises a bearing plate, a magnetized object and a plurality of guide elements movably arranged on the bearing plate, the bearing plate is arranged on the machine table, the magnetized object is arranged in the bearing plate, each guide element comprises a guide wheel and a metal column that can be magnetically attracted, the metal column is magnetically attracted to any position on the bearing plate, and the guide wheel is sleeved on the outside of one end of the metal column.

[0010] The beneficial effects of this utility model are:

[0011] 1. This device features multiple quickly adjustable guides in the tube-drawing section after the extruder has formed the tube. Combined with the effect of magnets flexibly fixing the metal column and guide wheel, the guide wheel is magnetically fixed to any position on the support plate. This allows the device to quickly adjust the traction path of the plastic tube according to actual production needs, making the traction direction adjustable instead of fixed. This reduces the adjustment complexity of traditional steering devices and greatly improves the dynamic adjustment capability of the production line.

[0012] Based on the above technical solution, the present invention can be further improved as follows.

[0013] Furthermore, the cooling assembly includes a cooling chamber, a water outlet pipe, a cooling pool, a clearance groove, and a through hole. The cooling chamber is located on the axis of the die opening of the extruder body. The cooling pool is fixed inside the cooling chamber. One end of the water outlet pipe extends to the top of the cooling pool. The clearance groove is opened on both sides of the cooling chamber. The through hole is opened on both sides of the cooling pool.

[0014] The beneficial effect of adopting the above-mentioned further solution is that cooling water is continuously injected into the cooling pool through the water outlet pipe, so that the inside of the cooling pool is always kept at a low temperature. After the plastic pipe body is formed by the extruder body, it enters the cooling chamber along the clearance groove and is immersed in the cooling pool through the penetration hole to achieve the cooling treatment of the pipe body. This avoids deformation or damage to the pipe body caused by the subsequent pipe pulling operation and ensures the molding stability of the plastic pipe body.

[0015] Furthermore, the axis of the through hole is coaxial with the die opening of the extruder body, and the depth of the clearance groove is greater than the diameter of the through hole.

[0016] The beneficial effect of adopting the above-mentioned further solution is that by keeping the axis of the through hole coaxial with the die opening, the movement path of the tube after extrusion molding is precisely aligned with the through hole, reducing the possibility of offset or jamming. At the same time, the depth of the clearance groove is greater than the diameter of the through hole, providing sufficient space to accommodate the tube and allowing it to smoothly enter the cooling pool.

[0017] Furthermore, the dragging unit includes a fixed plate in the shape of an inverted "U", a motor, a first drag wheel, and a second drag wheel. The fixed plate is located on one side of the cooling chamber. The first drag wheel and the second drag wheel are distributed opposite to each other, and one side of both is rotatably connected to the fixed plate via a rotating shaft.

[0018] Furthermore, the motor is fixed to the top of the fixed plate, and the drive end of the motor passes through the fixed plate and is connected to the first drag wheel.

[0019] The beneficial effect of adopting the above-mentioned further solution is that, by driving the first traction wheel to rotate through the motor, and since the pipe body is placed between the first traction wheel and the second traction wheel, the rotating first traction wheel can pull the pipe body to move.

[0020] Furthermore, the magnetized material is configured as an electromagnet.

[0021] The beneficial effect of adopting the above-mentioned further solution is that by controlling the on and off of the electromagnet, the magnetic state of the carrier plate can be flexibly switched, so that it has the ability to attract when needed (magnetic state) and loses its magnetism when not needed (non-magnetic state), which improves the convenience of operation and makes the movement or positioning of the metal column more efficient.

[0027] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0028] Plastic tube extrusion molding technology has been widely used in the field of plastic product manufacturing. After extrusion molding, the plastic tubes often need to go into different subsequent processes according to different production needs or customization requirements. For example, some plastic tubes need to go into the printing process to process surface patterns, while others only need to be simply cut.

[0029] However, most extruders currently use a single-direction linear traction method for the tube drawing section, which means that the extruded plastic tube can only move in a fixed direction. Furthermore, even if a turn is required, the turning device needs to be reinstalled according to the turning direction. Therefore, it lacks a flexible and convenient adjustment function for the traction path and cannot flexibly adjust the traction direction of the tube according to the accurate position of different processes, making it difficult to meet various processing needs. In response, the inventor has proposed a tube drawing machine with a guiding mechanism to solve the above problems.

[0030] The present invention provides the following preferred embodiments.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, a tube drawing machine with a guiding mechanism includes:

[0032] 100 machines;

[0033] Extruder body 200, which is mounted on machine base 100;

[0034] Cooling component 300 is located on one side of extruder body 200 and is used to cool the extruded plastic tube.

[0035] The tube pulling assembly 400 includes a dragging part 410 for dragging the plastic tube away from the extruder body 200 and a guide part 420 for adjusting the dragging direction. The dragging part 410 is located on one side of the cooling assembly 300 and is mounted on the machine base 100. The guide part 420 includes a support plate 421, a magnet 422, and a plurality of guide members 423 that move on the support plate 421. The support plate 421 is mounted on the machine base 100, the magnet 422 is located inside the support plate 421, and each guide member 423 includes a guide wheel 423b and a magnetically attracted metal column 423a. The metal column 423a is magnetically attracted to any position on the support plate 421, and the guide wheel 423b is sleeved on the outside of one end of the metal column 423a.

[0036] The device is designed with multiple quickly adjustable guides 423 in the tube pulling section after the extruder extrudes the tube. Combined with the effect of magnets 422 flexibly fixing the metal column 423a and the guide wheel 423b, the guide wheel 423b is magnetically fixed to any position on the support plate 421. This allows the device to quickly adjust the traction path of the plastic tube according to actual production needs, changing the traction direction from fixed to adjustable. This reduces the adjustment complexity of traditional steering devices and greatly improves the dynamic adjustment capability of the production line.

[0037] In this embodiment, as Figure 1 , Figure 2 and Figure 3As shown, the cooling assembly 300 includes a cooling chamber 301, a water outlet pipe 302, a cooling pool 303, a clearance groove 304, and a through hole 305. The cooling chamber 301 is located on the axis of the die opening of the extruder body 200. The cooling pool 303 is fixed inside the cooling chamber 301. One end of the water outlet pipe 302 extends to the top of the cooling pool 303. The clearance groove 304 is opened on both sides of the cooling chamber 301, and the through hole 305 is opened on both sides of the cooling pool 303. Cooling water is continuously injected into the cooling pool 303 through the water outlet pipe 302, so that the interior of the cooling pool 303 is always kept at a low temperature. After the plastic tube is formed by the extruder body 200, it enters the cooling chamber 301 along the clearance groove 304 and is immersed in the cooling pool 303 through the through hole 305 to achieve the cooling treatment of the tube. This avoids deformation or damage to the tube during subsequent tube pulling operations and ensures the forming stability of the plastic tube.

[0038] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the axis of the through hole 305 is coaxial with the die opening of the extruder body 200, and the depth of the clearance groove 304 is greater than the diameter of the through hole 305. By keeping the axis of the through hole 305 coaxial with the die opening, the movement path of the tube after extrusion is precisely aligned with the through hole 305, reducing the possibility of offset or jamming. At the same time, the depth of the clearance groove 304 is greater than the diameter of the through hole 305, providing sufficient space to accommodate the tube so that the tube can smoothly enter the cooling pool 303.

[0039] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the dragging unit 410 includes a fixed plate 411 in the shape of an inverted "U", a motor 412, a first drag wheel 413, and a second drag wheel 414. The fixed plate 411 is located on one side of the cooling chamber 301. The first drag wheel 413 and the second drag wheel 414 are distributed opposite to each other, and one side of both are rotatably connected to the fixed plate 411 through a rotating shaft. The motor 412 is fixed to the top of the fixed plate 411, and the drive end of the motor 412 passes through the fixed plate 411 and is connected to the first drag wheel 413. The motor 412 drives the first drag wheel 413 to rotate. Since the tube is placed between the first drag wheel 413 and the second drag wheel 414, the rotating first drag wheel 413 can pull the tube to move.

[0040] In this embodiment, as Figure 3 As shown, the magnet 422 is an electromagnet. By controlling the on and off of the electromagnet, the magnetic state of the carrier plate 421 can be flexibly switched, so that it has the ability to attract when needed (magnetic state) and loses its magnetism when not needed (non-magnetic state), which improves the convenience of operation and makes the movement or positioning of the metal column 423a more efficient.

[0041] The specific working process of this utility model is as follows:

[0042] First, based on different production needs or customization requirements, the subsequent processing position of the tube body is determined. For example, some plastic tube bodies need to enter the printing process for surface pattern printing, while others only need simple cutting. When targeting the processing position of the printing process, a guide 423 that can guide the tube body to move along the printing process direction is placed on the support plate 421 to form a moving path to the printing process. At the same time, the electromagnet is energized so that the support plate 421 has the ability to attract (magnetic state), which can strongly attract the metal column 423a (the metal column 423a is made of steel or iron), thereby fixing the position of the fast guide wheel 423b.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
