Abstract
Description
Technical Field
[0001] This utility model relates to the field of MPP pipe technology, and in particular to a traction conveying device for MPP pipe production. Background Technology
[0002] In the production process of MPP pipes (modified polypropylene pipes), the traction conveyor is a key piece of equipment connecting extrusion molding, cooling and shaping, and subsequent cutting and inspection processes. Its core function is to achieve stable transmission and posture calibration of the MPP pipes, directly affecting the production efficiency and finished product quality. However, existing traction conveyor devices for MPP pipe production still have certain shortcomings in practical applications, making it difficult to meet the needs of efficient and precise transmission of MPP pipes of different specifications.
[0003] Existing traction conveying devices mostly use fixed welded side limiting structures, whose spacing cannot be flexibly adjusted according to the diameter of the MPP pipe. When conveying MPP pipes with smaller diameters, a large gap is easily generated between the pipe body and the side structure, causing the pipe body to shift laterally, roll, or even get stuck during the conveying process. When conveying MPP pipes with larger diameters, the fixed spacing of the side structure will squeeze the pipe body, which may cause scratches and deformation on the pipe surface. In severe cases, it may also damage the uniformity of the pipe wall thickness and increase the defect rate. Therefore, this application proposes a traction conveying device for MPP pipe production. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a traction conveying device for MPP pipe production, so as to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a traction conveying device for MPP pipe production, comprising: The processing table has a transport trough on the top, and a conveyor belt is installed inside the transport trough. A first motor is installed on the outside of the processing table, and the output end of the first motor is connected to one end of the conveyor belt. There are two sets of movable plates. Both movable plates are located on the top of the processing table and on both sides of the conveyor belt, and the tops of both movable plates are inclined towards the conveyor belt. The side baffle assembly is provided in two sets and is installed on the top of the two moving plates respectively. Both side baffle assemblies are inclined and symmetrically arranged on the top of the conveyor belt. The synchronization component is located at the middle position of the bottom of the processing table and is connected to the two moving plates.
[0006] Optionally, the top of the conveyor belt is higher than the processing table. Guide rods are installed at both ends of the top of the processing table. Both guide rods pass through the conveyor belt. Through holes are opened at the two corners of the bottom side of the two moving plates, and the two through holes at the bottom of the moving plates are respectively fitted onto the two guide rods.
[0007] Optionally, the side guard assembly includes a fixed frame, rollers, a first gear, and an extension plate. Several fixed frames are arranged in an orderly manner, and each fixed frame is fixedly installed on the top of the movable plate. The number of rollers is the same as the number of fixed frames, and each roller is rotatably installed on the corresponding fixed frame. The shaft at the top of each roller passes through the fixed frame. The number of first gears is the same as the number of rollers, and each first gear is installed on the shaft at the top of the corresponding roller. The extension plate is installed on the side of the top of several fixed frames away from the rollers.
[0008] Optionally, the side stop assembly also includes a transmission gear, a second motor, and a second gear. A fixed shaft is fixedly installed on the top of the extension plate between each pair of adjacent first gears. A bearing is fixedly sleeved on each fixed shaft. The number of transmission gears is the same as the number of bearings. Each transmission gear is sleeved on a corresponding bearing. The size of the transmission gear is larger than that of the first gear, and the sidewall of each transmission gear is meshed with the sidewall of each of the two adjacent first gears. The second motor is installed at the bottom of one end of the extension plate, and the output end of the second motor passes through the extension plate. The second gear is installed at the output end of the second motor, and the sidewall of the second gear is meshed with one of the transmission gears.
[0009] Optionally, slots are provided at the middle positions on both sides of the processing table, and an opening is provided at the lower position between the two slots. The synchronization component is installed in the two slots and the opening.
[0010] Optionally, the synchronization component includes two support plates, a third motor, and a third gear. The support plates are L-shaped, with the tops of the vertical sections of the two support plates fixedly connected to the outer sides of the two movable plates. The vertical sections of the two support plates are located in two notches, and the horizontal sections of the two support plates are inserted into the through-hole. The horizontal sections of the two support plates are distributed vertically within the through-hole. The horizontal sections of the two support plates are provided with toothed grooves, and the teeth on the inner walls of the two toothed grooves are staggered, one on the left and one on the right. The third motor is installed at the center of the bottom of the processing table, and the output end of the third motor extends into the through-hole. The third gear is fixedly installed on the output end of the third motor and is located in the toothed grooves of the horizontal sections of the two support plates. The two sides of the third gear are respectively engaged with the teeth in the two toothed grooves.
[0011] The beneficial effects of this utility model are: Through the coordinated action of the synchronization component and the moving plate, the spacing between the side baffle components on both sides can be flexibly adjusted. In the synchronization component, when the third motor drives the third gear to rotate, because the tooth grooves on the horizontal parts of the two support plates are staggered, the third gear can simultaneously drive the two support plates to move synchronously in opposite directions, thereby driving the moving plates on both sides to slide smoothly along the guide rod, realizing precise adjustment of the spacing between the side baffle components. This broadens the adaptability of the device to MPP pipes of different specifications and reduces production interruptions and defective products caused by insufficient equipment adaptability.
[0012] The side baffle assembly adopts a multi-roller array design. The rollers are rotatably mounted on the top of the moving plate through a fixed frame and are inclined to fit the side wall of the MPP tube. When the MPP tube is conveyed on the conveyor belt, there is rolling friction between the tube body and the rollers. Compared with the sliding friction of the traditional fixed side baffle, the frictional resistance and wear probability of the tube surface are greatly reduced, effectively protecting the surface smoothness and wall thickness uniformity of the MPP tube, and reducing quality problems such as surface scratches and uneven wall thickness caused by friction.
[0013] In the side baffle assembly, the second motor drives the transmission gear to rotate through the second gear, and the transmission gear then drives the adjacent first gear to rotate synchronously through meshing, ultimately achieving the same direction and speed rotation of all rollers. The active rotation of the rollers can generate auxiliary traction force on the MPP pipe, which works in coordination with the conveyor belt to avoid the pipe from jamming or deviating due to uneven force during the conveying process, further ensuring the stability of the conveying process.

Detailed Implementation
[0015] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0016] Please see Figures 1-7 This utility model provides a technical solution: a traction conveying device for MPP pipe production, including a processing table 1, a transport trough 11 on the top of the processing table 1, a conveyor belt 12 arranged inside the transport trough 11, a first motor 13 installed on the outside of the processing table 1, the output end of the first motor 13 connected to one end of the conveyor belt 12, and movable plates 22 arranged on the top of the processing table 1 and on both sides of the conveyor belt 12, the tops of the two movable plates 22 inclined towards the conveyor belt 12, and side baffle assemblies 3 installed on the tops of the two movable plates 22, the two side baffle assemblies 3 being inclined and symmetrically arranged on the conveyor belt 12. At the top of the processing table 1, a synchronization component is set at the middle position of the bottom. The synchronization component is connected to two moving plates 22. The first motor 13 drives the conveyor belt 12 to realize the basic conveying of MPP pipes. The moving plates 22 and side baffle components 3 set on both sides can limit the pipe body. The synchronization component provides power for the adjustment of the moving plates 22. The overall structure breaks through the traditional fixed limit design. The side baffle spacing can be adjusted by the cooperation of the synchronization component and the moving plates 22 to adapt to different specifications of MPP pipes, reduce production interruptions and defective products caused by insufficient adaptation. At the same time, the inclined side baffle components 3 can better fit the pipe body and ensure the stability of conveying.
[0017] like Figure 1 and Figure 2As shown, the top of the conveyor belt 12 is higher than the processing table 1. Guide rods 21 are installed at both ends of the top of the processing table 1, and both guide rods 21 pass through the conveyor belt 12. Through holes 221 are opened at the two corners of the bottom side of the two moving plates 22, and the two through holes 221 at the bottom of the moving plates 22 are respectively fitted onto the two guide rods 21. Setting the height of the conveyor belt 12 higher than the processing table 1 can avoid friction between the pipe and the processing table 1 during pipe transportation. The guide rods 21 at both ends pass through the conveyor belt 12 and cooperate with the through holes 221 at the bottom of the moving plates 22 to provide a precise sliding track for the moving plates 22. This design allows the moving plates 22 to move smoothly along the guide rods 21 under the drive of the synchronous components, preventing deviation and jamming during adjustment, ensuring symmetrical and precise adjustment of the spacing between the side baffle components 3 on both sides, further improving the adaptation accuracy of MPP pipes of different diameters, while reducing wear on the moving plates 22 and extending the service life of the device.
[0018] like Figure 3 , Figure 4 and Figure 5 As shown, the side guard assembly 3 includes a fixed frame 31, rollers 32, first gears 33, and an extension plate 34. Several fixed frames 31 are arranged in an orderly manner, and each fixed frame 31 is fixedly mounted on the top of the movable plate 22. The number of rollers 32 is the same as the number of fixed frames 31, and each roller 32 is rotatably mounted on its corresponding fixed frame 31. The shaft at the top of each roller 32 passes through the fixed frame 31. The number of first gears 33 is the same as the number of rollers 32, and each first gear 33 is mounted on the shaft at the top of its corresponding roller 32. The extension plate... The 34 is installed on the side away from the roller 32 at the top of several fixed frames 31. The several fixed frames 31 are arranged in an orderly manner to provide a stable installation base for the roller 32. The roller 32 is rotated and installed between the fixed frames 31. When it comes into contact with the MPP pipe, it forms rolling friction, which greatly reduces the wear on the pipe surface and protects the smoothness and uniformity of the pipe wall thickness. The first gear 33 is connected to the shaft of the roller 32 to provide a transmission base for the subsequent active rotation of the roller 32. The outer plate 34 integrates the fixed frames 31, enhances the overall structural stability of the side baffle assembly 3, and makes the limiting and conveying process more reliable.
[0019] like Figure 3 , Figure 4 and Figure 5As shown, the side guard assembly 3 also includes a transmission gear 36, a second motor 37, and a second gear 38. A fixed shaft is fixedly installed on the top of the extension plate 34 between each pair of adjacent first gears 33. A bearing 35 is fixedly sleeved on each fixed shaft. The number of transmission gears 36 is the same as the number of bearings 35. Each transmission gear 36 is sleeved on a corresponding bearing 35. The size of the transmission gear 36 is larger than that of the first gear 33, and the sidewall of each transmission gear 36 meshes with the sidewall of each of the two adjacent first gears 33. The second motor 37 is installed at the bottom of one end of the extension plate 34, and the output end of the second motor 37 penetrates through the extension plate 34. The second gear 38 is installed on... The output end of the second motor 37 and the side wall of the second gear 38 are meshed with one of the transmission gears 36. The second motor 37 drives the transmission gear 36 through the second gear 38. The transmission gear 36 then meshes with and drives the adjacent first gear 33, ultimately achieving the same rotation speed and direction of all rollers 32. The active rotation of the rollers 32 can provide auxiliary traction force for the MPP pipe, coordinating with the conveyor belt 12 to prevent the pipe from jamming or shifting due to uneven force. The transmission gear 36 is larger than the first gear 33, which can optimize transmission efficiency and stability. The bearing 35 reduces the rotational friction of the transmission gear 36, ensuring long-term stable operation of the transmission system and significantly improving the smoothness and efficiency of the conveying process.
[0020] like Figure 2 and Figure 6 As shown, slots 14 are provided in the middle of both sides of the processing table 1, and an opening 15 is provided in the lower part between the two slots 14. The synchronization component is installed in the two slots 14 and the opening 15. The design of the slots 14 on both sides of the processing table 1 and the middle opening 15 allows the synchronization component to be embedded in the processing table 1, avoiding the occupation of external space and making the overall structure of the device more compact. The slots 14 play a limiting and guiding role for the vertical part of the support plate 41, while the opening 15 provides space for the horizontal part of the support plate 41 to move, ensuring that the components of the synchronization component do not interfere with the processing table 1 when the synchronization component is running. At the same time, it protects the synchronization component from external collisions and dust, extends its service life, and provides a stable environment for the precise adjustment of the distance between the two sets of side baffle components 3.
[0021] like Figure 3 , Figure 6 and Figure 7As shown, the synchronization assembly includes two support plates 41, a third motor 43, and a third gear 44. The support plates 41 are L-shaped. The top ends of the vertical parts of the two support plates 41 are fixedly connected to the outer sides of the two moving plates 22, and the vertical parts of the two support plates 41 are respectively located in the two notches 14. The horizontal parts of the two support plates 41 are inserted into the through-holes 15, and the horizontal parts of the two support plates 41 are distributed vertically within the through-holes 15. The horizontal parts of the two support plates 41 are provided with toothed grooves 42, and the teeth on the inner walls of the two toothed grooves 42 are staggered from left to right. The third motor 43 is installed at the center of the bottom of the processing table 1, and the output end of the third motor 43 extends into the through-hole 15. The third gear 44 is fixedly installed on the output end of the third motor 43, and the third gear 44 is located in the two notches 14. Within the toothed grooves 42 of the horizontal section of the support plate 41, the two sides of the third gear 44 mesh with the teeth in the two toothed grooves 42 respectively. The L-shaped support plate 41 connects the moving plate 22 and the synchronization component. The horizontal section is distributed vertically and the toothed grooves 42 are staggered. When the third motor 43 drives the third gear 44, the third gear 44 meshes with the teeth in the two toothed grooves 42 and rotates simultaneously. This can simultaneously drive the two support plates 41 to move synchronously in opposite directions, realizing symmetrical adjustment of the distance between the two moving plates 22 and the side stop components 3, avoiding pipe body offset caused by unilateral adjustment. The gear meshing transmission has high precision, can accurately control the distance between the side stop components 3, adapts to MPP pipes of different diameters, and the transmission process is stable without slippage, ensuring the reliability of the side stop components 3 in limiting the pipe body after adjustment, further reducing the generation of defective products.
