Description

Technical Field

[0001] This utility model relates to the field of plastic pipe production technology, specifically to a winding pultrusion equipment with a cleaning function. Background Technology

[0002] As an advanced plastic pipe production equipment, the filament winding and pultrusion equipment plays a key role in the plastic pipe manufacturing industry. Through its unique design and advanced control technology, the equipment realizes the automatic winding and pultrusion molding of the outer wall material of plastic pipes, which greatly improves production efficiency and product quality.

[0003] In the production process of this equipment, after the outer wall of the plastic pipe is wrapped, the pipe needs to be cut. However, the cutting process inevitably generates shavings and dust, which are very easy to adhere to and remain on the inner wall of the pipe.

[0004] The mechanical vibrations generated by the equipment during operation, along with its own motion, cause the dust inside the plastic tube to be shaken off and carried out. Since the servo motor generates a lot of heat during operation, heat sinks are usually provided to ensure stable operation of the motor and achieve effective heat dissipation. However, in the actual production environment, due to the dust generated by the cutting spreading everywhere, the heat sinks are easily clogged by dust, which seriously affects the service life of the motor and the reliability of the entire equipment.

[0005] Meanwhile, due to the diverse demands of the plastic pipe market, different application scenarios have different requirements for the inner diameter of the pipes, resulting in significant differences in the size of the inner diameter opening. Most existing cleaning equipment has a fixed structure and lacks a flexible adjustment mechanism, making it difficult to adapt to the cleaning needs of pipes with different inner diameters. Using incompatible cleaning equipment will lead to incomplete cleaning of the inside of the pipes.

[0006] In view of the above, this application is hereby submitted. Utility Model Content

[0007] The purpose of this invention is to provide a winding pultrusion device with a cleaning function to solve the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, this utility model provides a winding pultrusion device with a cleaning function, including a fixed plate and two abutments. An internal gear ring is rotatably mounted on the sidewall of each abutment. Twenty-four driven gears are meshed with the inner wall of each internal gear ring. Clamping plates are fixedly mounted on the outer walls of the twenty-four driven gears, and adjacent clamping plates are arranged alternately. An external tooth groove is formed on the outer wall of the internal gear ring, and a drive gear is meshed with the outer wall of the external tooth groove. The drive gear is fixedly mounted on the drive end of a motor. A clamping rod is fixedly mounted on the sidewall of the motor. A sealing ring is fixedly mounted on the sidewall of the internal gear ring. A clamping plate is slidably mounted on the sidewall of the sealing ring. An air blowing pipe is fixedly connected to the inner wall of one clamping plate, and a dust suction pipe is fixedly mounted on the inner wall of the other clamping plate.

[0009] Furthermore, a connecting rod 1 is rotatably mounted at both ends of the pull plate, a connecting rod 2 is rotatably mounted at one end of the connecting rod 1, a connecting rod 3 is rotatably mounted at the other end of the connecting rod 2, and the end of the connecting rod 3 is rotatably connected to the inner wall of the clamping rod.

[0010] A connecting rod four is rotatably mounted on the end of the fixed plate away from the motor, and the end of the connecting rod four is rotatably connected to the inner wall of the clamping rod.

[0011] Furthermore, a semi-fixed ring is fixedly installed on the side of the abutment away from the sealing ring. The semi-fixed ring is made of flexible rubber. An air blowing device is connected to the end of the air blowing pipe, and a dust collection device is connected to the end of the dust suction pipe.

[0012] Furthermore, a sealing gasket is provided at the end of the clamp away from the driven gear, and the surface of the rubber gasket is coated with an anti-stick coating.

[0013] Furthermore, a motor is fixedly installed on the top of the fixing plate, a screw is fixedly installed on the drive end of the motor, and a pull plate is threaded onto the outer wall of the screw.

[0014] Furthermore, the outer wall of the abutment is fixedly connected to the end of the clamping rod, and the abutment is coated with an anti-stick coating.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The blowing device blows high-speed airflow through the blowing pipe to the inner wall of the plastic tube, thoroughly blowing up the dust and shavings attached to the inner wall. At the same time, the dust collection device generates a strong negative pressure through the suction pipe, quickly sucking in the blown-up impurities. This synergistic effect of blowing and suction achieves efficient cleaning of the inner wall of the plastic tube, effectively preventing dust from being carried out and diffused into the external environment during the feeding process due to mechanical vibration and equipment movement.

[0017] This eliminates the spread of dust at the source, ensures the cleanliness of the environment around the motor heat sink, and allows the heat generated by the motor to be dissipated in a timely and effective manner through the heat sink. This avoids problems such as decreased motor performance, reduced operating efficiency, or even damage caused by overheating, and extends the service life of the motor.

[0018] When clamping plastic pipes, the motor drives the screw to rotate, which moves the pull plate. This, in turn, causes the clamping rod to move the abutment plates closer together to clamp the pipe through the linkage mechanism. Subsequently, the motor drives the drive gear to rotate, which in turn causes the internal gear ring to rotate on the side wall of the abutment plate. This causes the clamping plate, which is fixedly connected to the driven gear, to rotate accordingly. Because the adjacent clamping plates are arranged in an alternating manner, the opening between the clamping plates can be automatically adjusted according to the size of the opening on the inner wall of the pipe during rotation. This eliminates the need to customize special cleaning equipment for pipes of different diameters, reducing the company's equipment procurement costs and customization cycle.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4This utility model provides a technical solution: a winding pultrusion device with a cleaning function, comprising two abutment plates 11 with internal gear rings 16 rotatably mounted on their side walls, twenty-four driven gears 18 meshing with the inner walls of the internal gear rings 16, and a clamping plate 12 fixedly mounted on the outer wall of each driven gear 18, with adjacent clamping plates 12 arranged alternately to form a ring cleaning array. When the motor 14 drives the drive gear 15 at its drive end to rotate, the drive gear 15 precisely meshes with the outer tooth groove 17 on the outer wall of the internal gear ring 16, efficiently transmitting power to the internal gear ring 16, allowing it to rotate smoothly. As the internal gear ring 16 rotates, the twenty-four driven gears 18 rotate synchronously, thereby adjusting the opening between the clamping plates 12 to be equal to the size of the inner wall of the tube. At this time, the blowing device delivers a high-speed airflow to the blowing pipe 19, which thoroughly blows away the chips and dust attached to the corners of the inner wall of the plastic tube, freeing them from the tube wall. At the same time, the dust collection device starts synchronously, generating negative pressure through the suction pipe 20, realizing seamless coordinated operation of blowing and suction, which can thoroughly remove impurities in the tube, improve the thoroughness of cleaning, and avoid impurity residue affecting the quality of subsequent processing.

[0026] Please see Figure 1 This utility model provides a technical solution: a winding pultrusion device with cleaning function, including a motor 2 fixedly installed on the top of a fixed plate 1, whose drive end is directly connected to a screw 3. The rotational kinetic energy is precisely converted into linear motion through threaded engagement. When the motor 2 starts, the rotation of the screw 3 drives the pull plate 4, which is threadedly engaged with it, to move smoothly along the axial direction. The axial movement of the pull plate 4 is further converted into clamping force through a multi-link mechanism with double-end hinges. The first link 5 is rotatably connected to the third link 7 after passing through the second link 6, and finally transmits the power to the rotation fulcrum of the inner wall of the clamping rod 9. At the same time, the fourth link 8 set at the far end of the fixed plate 1 and the inner wall of the clamping rod 9 form a spatial four-bar linkage structure with the aforementioned three links. When the pull plate 4 moves, the four links convert the linear displacement into the precise opening and closing movement of the clamping rod 9 through compound oscillation, ensuring that the end of the clamping rod 9 always moves in a planar parallel motion along a predetermined path.

[0027] Please see Figure 2 This utility model provides a technical solution: a filament winding pultrusion device with cleaning function, including a backing plate 11 whose outer wall is fixedly connected to the end of a clamping rod 9. The backing plate 11 is coated with an anti-stick coating. A semi-fixed ring 10 is fixedly installed on the side of the backing plate 11 away from the sealing ring 13. The semi-fixed ring 10 is made of flexible rubber. During the filament winding pultrusion process, the pipe needs to undergo multiple processes such as resin impregnation, fiber winding, and high-temperature curing. The anti-stick coating can effectively prevent resin residue or cured material from adhering to the surface of the backing plate 11, reducing the frequency of equipment downtime for cleaning and improving production continuity. The flexible rubber absorbs the impact energy between the pipe and the backing plate 11 at the moment of clamping, avoiding cracking or deformation of the pipe end caused by hard contact.

[0028] Working principle: Start motor 2, which drives screw 3 to rotate. Since pull plate 4 is threadedly connected to screw 3, under the action of threaded transmission, pull plate 4 moves axially along screw 3. During the movement of pull plate 4, it drives connecting rod 5 to move, which in turn drives connecting rods 6, 7, and 8 to move, causing clamping rod 9 to move towards the center. The end of clamping rod 9 is fixedly connected to the outer wall of abutment plate 11, thereby causing the two abutment plates 11 to move closer together, clamping the plastic tube between the two abutment plates 11. At this time, start motor 14, and the drive gear 15 fixed at the drive end of motor 14 begins to rotate. Since drive gear 15 meshes with the outer tooth groove 17 on the outer wall of inner gear ring 16, the rotation of drive gear 15 drives inner gear ring 16 to rotate on the side wall of abutment plate 11. Twenty-four driven gears 18 are meshed on the inner wall of inner gear ring 16. When inner gear ring 16 rotates, it drives the driven gears 18 to rotate, thereby causing clamping plate 12 fixedly installed on the outer wall of driven gears 18 to rotate. Adjacent clamping plates 12 are arranged in an alternating pattern until the opening between the clamping plates 12 is equal to the opening of the inner wall of the pipe. At this time, the air blowing device is activated, blowing a high-speed airflow through the air blowing pipe 19 to the inner wall of the plastic pipe, blowing up the chips and dust attached to the inner wall. At the same time, the dust collection device is activated, generating negative pressure through the dust suction pipe 20 to quickly suck up the blown dust and chips, thus cleaning the inner wall of the plastic pipe. This effectively prevents dust from being carried out and spreading to the external environment due to mechanical vibration and equipment movement during subsequent material feeding. After the inner wall of the plastic pipe is cleaned, the motor 2 rotates in the reverse direction, driving the screw 3 to rotate in the reverse direction, causing the pull plate 4 to move in the reverse direction along the screw 3, driving the linkage mechanism to move. The clamping rod 9 unfolds outward, and the two abutment plates 11 move away from each other, releasing the plastic pipe. At this time, the cleaned plastic pipe can be taken out of the equipment for subsequent material feeding or other processing procedures.

[0029] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
