Description

Technical Field

[0001] This utility model relates to the field of plastic pipe processing technology, specifically to an extrusion device for MPP cable protection pipes. Background Technology

[0002] MPP cable protection pipe is a type of pipe made from modified polypropylene. It features high temperature resistance, high pressure resistance, and corrosion resistance, and is widely used in cable laying protection in power, communication, and other fields. The extrusion unit is the core equipment in the production of MPP cable protection pipe. It extrudes molten MPP raw material into shape, cools and solidifies it, and then draws and cuts it into pipes of a fixed length, directly affecting the dimensional accuracy and mechanical properties of the pipe.

[0003] According to a disclosed MPP cable protection tube extrusion device (publication number: CN219325506U), it includes: a main unit and a protection unit, which includes a connecting plate disposed on the upper surface of a power box, a motor disposed on the inner surface of the connecting plate, a rotating shaft disposed on the output end of the motor, a fan blade disposed on the outer surface of the rotating shaft, a suction pipe disposed on the outer right side of the connecting plate, a support plate disposed on the upper surface of the suction pipe, and a filter assembly disposed on the inner surface of the support plate. Its beneficial effects are: the support plate absorbs impurities from the air; when the MPP cable protection tube raw material enters the extrusion tube, it is filtered through the second filter plate and storage box in the filter assembly. The angle of the second filter plate is inclined, preventing the raw material from clogging. The operation of the protection unit provides sufficient protection for the raw material, resulting in a more aesthetically pleasing extruded appearance of the MPP cable protection tube and reduced impurity content, thereby improving the quality of the MPP cable protection tube.

[0004] In the above application, the filtering and dust collection structure of the protection unit effectively removes impurities from the raw materials and improves the basic quality of the MPP cable protection pipe. However, it lacks a precise cutting mechanism for the formed pipe. The existing cutting method is prone to skewed pipe cuts and large length errors due to unstable transmission. Therefore, we propose an extrusion device for MPP cable protection pipe. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides an MPP cable protection pipe extrusion device, which solves the problem of low cutting accuracy in the prior art.

[0006] According to one aspect, at least one embodiment of the present invention provides an extrusion device for MPP cable protection pipes, comprising: a processing frame, an extrusion box fixedly connected to the top of the processing frame, a cooling box fixedly connected to the top of the processing frame, a wire pulling box fixedly connected to the top of the processing frame, and a cutting device provided on the side of the processing frame; The cutting device includes a mounting plate, the side of which is fixedly connected to the side of the processing frame. A slide rail is fixedly connected to the side of the mounting plate, and a cutting plate is slidably connected to the side of the slide rail. A transmission block is fixedly connected to the side of the cutting plate. A transmission pulley is rotatably connected to the side of the mounting plate, and a positioning wheel is rotatably connected to the side of the mounting plate. A motor bracket is fixedly connected to the bottom of the processing frame, and a drive motor is fixedly connected to the inner circumferential surface of the motor bracket. The output shaft of the drive motor passes through and is rotatably connected to the side of the mounting plate, and a drive pulley is fixedly connected to the output shaft of the drive motor.

[0007] For example, in at least one embodiment of the present invention, an extrusion device for an MPP cable protection tube is provided, which further includes: a belt is provided on the circumferential surface of the drive pulley, the drive pulley is connected to the transmission pulley and the positioning wheel through the belt, the drive pulley drives the transmission pulley and the positioning wheel simultaneously through the belt, realizing the coordinated action of multiple components from a single power source and simplifying the transmission structure; the belt drive has a buffering and vibration reduction effect, which can reduce the rigid impact during cutting, protect the drive motor and transmission components, and extend the service life of the device.

[0008] The transmission pulleys are provided in two symmetrical configurations along the vertical central axis of the mounting plate. The outer circumferential surface of the positioning wheel is on the same horizontal line as the outer circumferential surface of the transmission pulley. The two symmetrical transmission pulleys ensure that the force on both sides of the belt is balanced, preventing belt deviation. The positioning wheel and the transmission pulley are kept on the same horizontal line to ensure consistent belt tension, stable transmission without slippage, and accurate movement of the cutting plate.

[0009] The inner wall of the transmission block is fixedly connected to the side of the belt. There are two cutting plates, which are symmetrical to each other along the vertical central axis of the mounting plate. The transmission block is fixed to the belt so that the cutting plates can move synchronously with the belt. The transmission response is fast. The two symmetrical cutting plates can cut the MPP cable protection pipe from both sides at the same time. The force is balanced to avoid pipe deformation and improve the flatness of the cut surface.

[0010] An auxiliary light rod is fixedly connected to the side of the mounting plate. The circumferential surface of the auxiliary light rod passes through and is slidably connected to the side of the cutting plate. The auxiliary light rod provides additional guiding support for the cutting plate, restricting the cutting plate to slide only along a straight line, avoiding tilting or deviation during movement, further ensuring accurate cutting position and improving cutting stability.

[0011] According to another aspect, at least one embodiment of the present invention also provides an MPP cable protection pipe extrusion device, comprising: a cleaning device, the cleaning device including a mounting base, the top of the mounting base being fixedly connected to the bottom of a processing frame, a cleaning box being fixedly connected to the top of the mounting base, a drive wheel being fixedly connected to the output end of a drive motor, an extension rod being fixedly connected to the side of the drive wheel, a transmission shaft being fixedly connected to the side of the extension rod, a push-pull rod being rotatably connected to the outer circumferential surface of the transmission shaft, and a cleaning rod being rotatably connected to the inner circumferential surface of one end of the push-pull rod.

[0012] For example, in at least one embodiment of the present invention, an extrusion device for an MPP cable protection tube is provided, which further includes: a rack fixedly connected to the inner wall side of the cleaning box, and a gear fixedly connected to one end of the cleaning rod. The gear and the rack mesh with each other, and the meshing of the gear and the rack converts the linear motion of the cleaning rod into rotational motion, so that the cleaning rod rotates while moving, thereby enhancing the wiping effect on the surface of the MPP cable protection tube. The meshing transmission accuracy is high, ensuring that the rotation and movement of the cleaning rod are synchronized, and improving the uniformity of cleaning.

[0013] The rack and gear are provided in pairs, and they are symmetrical to each other along the vertical central axis of the cleaning rod. The two symmetrical racks and gears drive the cleaning rod from both sides, so that the cleaning rod is subjected to balanced force, avoiding tilting or jamming caused by unilateral force, ensuring smooth and stable rotation and movement, and improving the operational reliability of the cleaning device.

[0014] A limiting rod is fixedly connected to the side of the gear, and a limiting groove is opened on the side of the cleaning box. The circumferential surface of the limiting rod is slidably connected to the inner wall of the limiting groove. The limiting rod slides in the limiting groove to further restrict the movement trajectory of the cleaning rod, prevent the gear and rack from disengaging, ensure stable transmission, and avoid radial shaking of the cleaning rod during movement, thus ensuring accurate cleaning position.

[0015] Rubber blades are fixedly connected to the circumference of the cleaning rod. Several rubber blades are arranged in a circular array along the vertical central axis of the cleaning rod. The rubber blades are soft and can effectively remove dust and residual impurities from the surface of the MPP cable protection pipe without scratching the pipe surface. The circular array distribution allows the cleaning rod to contact the pipe surface in all directions when it rotates, ensuring that there are no dead angles in the cleaning and improving the cleaning effect.

[0016] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model, a cutting device is used to achieve precise and stable cutting of MPP cable protection pipes. The drive motor drives the transmission pulley and positioning wheel to operate in coordination via the drive pulley and belt. The buffering effect of the belt drive reduces the cutting impact. Two symmetrical cutting plates move synchronously with the belt, cutting the pipe from both sides simultaneously. With the guidance of the auxiliary guide rod, the pipe is prevented from deforming under stress, ensuring a flat cut surface. The symmetrically distributed transmission pulley and positioning wheel ensure the stability of the belt drive and improve the cutting position accuracy, making it suitable for efficient cutting of pipes of different specifications.

[0017] 2. In this utility model, automatic pipe cleaning is achieved through the linkage of the cleaning device and the cutting device. The drive motor drives the drive wheel, extension rod and other components to push the cleaning rod to move. The meshing of the gear and rack makes the cleaning rod rotate simultaneously. The circumferential array of rubber blades can remove impurities from the pipe surface in all directions without causing scratches. The symmetrical rack and gear and the limiting rod limiting groove structure ensure the stable movement of the cleaning rod. Cleaning can be completed without an additional power source, saving energy while improving the cleanliness of the pipe after processing and ensuring the quality of subsequent use.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0022] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] like Figures 1-5 The present invention illustrates an MPP cable protection pipe extrusion device in one embodiment of the present invention, comprising: a processing frame 1, an extrusion box 2 fixedly connected to the top of the processing frame 1, a cooling box 3 fixedly connected to the top of the processing frame 1, a wire pulling box 4 fixedly connected to the top of the processing frame 1, and a cutting device 5 provided on the side of the processing frame 1. The cutting device 5 includes a mounting plate 501, the side of which is fixedly connected to the side of the processing frame 1. A slide rail 502 is fixedly connected to the side of the mounting plate 501. A cutting plate 503 is slidably connected to the side of the slide rail 502. A transmission block 504 is fixedly connected to the side of the cutting plate 503. A transmission pulley 505 is rotatably connected to the side of the mounting plate 501. A positioning wheel 506 is rotatably connected to the side of the mounting plate 501. A motor bracket 507 is fixedly connected to the bottom of the processing frame 1. A drive motor 508 is fixedly connected to the inner circumferential surface of the motor bracket 507. The output shaft of the drive motor 508 passes through and is rotatably connected to the side of the mounting plate 501. A drive pulley 509 is fixedly connected to the output shaft of the drive motor 508.

[0028] In some examples, a belt 510 is provided on the circumferential surface of the drive pulley 509. The drive pulley 509 is connected to the transmission pulley 505 and the positioning wheel 506 via the belt 510. The drive pulley 509 drives the transmission pulley 505 and the positioning wheel 506 simultaneously via the belt 510, realizing the coordinated action of multiple components from a single power source and simplifying the transmission structure. The belt 510 transmission has a buffering and vibration reduction effect, which can reduce the rigid impact during cutting, protect the drive motor 508 and transmission components, and extend the service life of the device. There are two drive pulleys 505, which are symmetrical to each other along the vertical central axis of the mounting plate 501. The outer circumferential surface of the positioning wheel 506 is on the same horizontal line as the outer circumferential surface of the drive pulley 505. The two symmetrical drive pulleys 505 make the force on both sides of the belt 510 even, and prevent the belt 510 from deviating. The positioning wheel 506 and the drive pulley 505 are on the same horizontal line to ensure that the belt 510 has consistent tension, the transmission process is stable and does not slip, and the cutting plate 503 moves accurately. The inner wall of the transmission block 504 is fixedly connected to the side of the belt 510. There are two cutting plates 503, which are symmetrical to each other along the vertical central axis of the mounting plate 501. The transmission block 504 is fixed to the belt 510 so that the cutting plates 503 can move synchronously with the belt 510. The transmission response is fast. The two symmetrical cutting plates 503 can cut the MPP cable protection pipe from both sides at the same time. The force is balanced to avoid pipe deformation and improve the flatness of the cut surface. An auxiliary light rod 511 is fixedly connected to the side of the mounting plate 501. The circumferential surface of the auxiliary light rod 511 passes through and is slidably connected to the side of the cutting plate 503. The auxiliary light rod 511 provides additional guiding support for the cutting plate 503, restricting the cutting plate 503 to slide only in a straight line, avoiding tilting or displacement during movement, further ensuring accurate cutting position and improving cutting stability.

[0029] For example, such as Figures 1-5 The operator starts the drive motor 508, whose output shaft drives the drive pulley 509 to rotate. The drive pulley 509 drives two symmetrical transmission pulleys 505 and positioning wheels 506 to rotate synchronously via the belt 510. Since the transmission block 504 is fixed to the side of the belt 510, the cyclical motion of the belt 510 drives the transmission block 504 and the cutting plate 503 to slide along the slide rail 502. At the same time, the auxiliary guide rod 511 guides the cutting plate 503 to prevent it from tilting. When the MPP cable protection pipe is transported to the cutting position through the cable box 4, the two symmetrical cutting plates 503 move towards the pipe with the belt 510 and cut the pipe from both sides simultaneously. After the cutting is completed, the belt 510 reverses its rotation, causing the cutting plates 503 to reset.

[0030] like Figures 1-5 This illustration shows an MPP cable protection pipe extrusion device according to another embodiment of the present invention, comprising: a cleaning device 6 provided on the side of the processing frame 1, the cleaning device 6 including a mounting base 601, the top of the mounting base 601 being fixedly connected to the bottom of the processing frame 1, a cleaning box 602 being fixedly connected to the top of the mounting base 601, a drive wheel 604 being fixedly connected to the output end of the drive motor 508, an extension rod 605 being fixedly connected to the side of the drive wheel 604, a drive shaft 606 being fixedly connected to the side of the extension rod 605, a push-pull rod 607 being rotatably connected to the outer circumferential surface of the drive shaft 606, and a cleaning rod 608 being rotatably connected to the inner circumferential surface of one end of the push-pull rod 607.

[0031] In some examples, a rack 603 is fixedly connected to the inner wall of the cleaning box 602, and a gear 609 is fixedly connected to one end of the cleaning rod 608. The gear 609 and the rack 603 mesh with each other, and the meshing of the gear 609 and the rack 603 converts the linear motion of the cleaning rod 608 into rotational motion, so that the cleaning rod 608 rotates while moving, which enhances the wiping effect on the surface of the MPP cable protection tube. The meshing transmission precision is high, ensuring that the rotation and movement of the cleaning rod 608 are synchronized, and improving the uniformity of cleaning. There are two racks 603 and two gears 609, and they are symmetrical to each other along the vertical central axis of the cleaning rod 608. The two symmetrical racks 603 and gears 609 drive the cleaning rod 608 from both sides, so that the cleaning rod 608 is subjected to balanced force, avoiding tilting or jamming caused by force on one side, ensuring smooth and stable rotation and movement, and improving the operational reliability of the cleaning device 6.

[0032] A limiting rod 610 is fixedly connected to the side of the gear 609, and a limiting groove 611 is opened on the side of the cleaning box 602. The circumferential surface of the limiting rod 610 is slidably connected to the inner wall of the limiting groove 611. The limiting rod 610 slides in the limiting groove 611, further restricting the movement trajectory of the cleaning rod 608, preventing the gear 609 from disengaging from the rack 603, ensuring stable transmission, and avoiding radial wobbling of the cleaning rod 608 during movement, thus ensuring accurate cleaning position. Rubber blades are fixedly connected to the circumference of the cleaning rod 608. Several rubber blades are arranged in a circular array along the vertical central axis of the cleaning rod 608. The rubber blades are soft and can effectively remove dust and residual impurities from the surface of the MPP cable protection pipe without scratching the pipe surface. The circular array distribution allows the cleaning rod 608 to contact the pipe surface in all directions when it rotates, ensuring that there are no dead corners in the cleaning and improving the cleaning effect.

[0033] For example, such as Figures 1-5 When the drive motor 508 is running, its output synchronously drives the drive wheel 604 to rotate. The drive wheel 604 drives the transmission shaft 606 to rotate in a circular motion via the extension rod 605. The transmission shaft 606 pulls the push-pull rod 607 to swing back and forth, causing the cleaning rod 608 to move linearly back and forth within the cleaning box 602. When the cleaning rod 608 moves, the gear 609 at its end meshes with the rack 603 on the inner wall of the cleaning box 602, causing the cleaning rod 608 to rotate while moving. The circular array of rubber blades rotates accordingly, wiping the surface of the MPP cable protection pipe passing through the cleaning box 602 in all directions. The limiting rod 610 on the side of the gear 609 slides along the limiting groove 611, ensuring that the gear 609 and the rack 603 are always meshed and that the cleaning rod 608 moves stably. The cleaning device 6 achieves automatic cleaning of the pipe and removes surface impurities without consuming additional power.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
