Description

Technical Field

[0001] The utility model relates to the technical field of a strapping belt production line, and specifically relates to a conveying mechanism of a strapping belt production line. Background Art

[0002] In the existing strapping belt production line, the conveying mechanism is an important part to ensure the stable transmission of the strapping belt. The traditional conveying mechanism usually adopts idler wheels with a fixed layout. Although this design is simple, there are some obvious deficiencies in the actual production process.

[0003] First of all, the idler wheels with a fixed layout cannot be adjusted horizontally or vertically according to the actual production situation. During the production process, the specifications and requirements of the strapping belt may change, and the fixed idler wheel layout cannot flexibly respond to these changes, resulting in uneven tension and unstable transmission of the strapping belt during the conveying process. Especially when dealing with strapping belts of different specifications, the fixed idler wheel layout may not provide appropriate support, thus affecting the transmission quality and production efficiency of the strapping belt.

[0004] Secondly, in order to ensure the stable transmission of the strapping belt, the idler wheels must be able to rotate smoothly. However, in the existing technology, the design of the idler wheels with adjustable positions makes it difficult to stably transmit power to the idler wheels, which may cause some idler wheels to rotate unstably, affecting the reliability and efficiency of the overall conveying system.

[0005] Therefore, the existing conveying mechanism has certain limitations in meeting the requirements of stable transmission of the strapping belt. There is a need for a design of a conveying mechanism that can flexibly adjust the position of the idler wheels according to the actual production requirements to improve the stability and reliability of the strapping belt transmission, and at the same time ensure the stable transmission of power. Content of the Utility Model

[0006] Aiming at the above deficiencies existing in the prior art, the purpose of the utility model is to provide a conveying mechanism of a strapping belt production line, which overcomes the deficiencies of the traditional conveying mechanism and significantly improves the performance and reliability of the strapping belt production line.

[0007] The technical solution adopted by the present utility model to achieve the above object is: a conveying mechanism for a strapping tape production line, including a processing box and a plurality of groups of conveying units assembled in the processing box and arranged horizontally. The conveying unit includes a horizontal adjustment frame, a vertical adjustment frame, a mounting shaft, a supporting wheel, and a transmission component. The horizontal adjustment frame is movably installed in the processing box and slides horizontally. The vertical adjustment frame is slidably installed on the horizontal adjustment frame and moves up and down vertically. The vertical adjustment frame is associated with the horizontal adjustment frame through a lifting adjustment component. The mounting shaft is rotatably installed on the vertical adjustment frame, and a plurality of groups of the supporting wheels are fixedly connected to the mounting shaft at equal intervals. The transmission component is assembled on the vertical adjustment frame and is in power connection with the mounting shaft.

[0008] It further includes a driving motor fixedly installed outside the processing box. A spline main shaft arranged horizontally is fixedly connected to the output shaft of the driving motor. The spline main shaft is rotatably installed outside the processing box and is in power connection with each group of the transmission components.

[0009] In some embodiments, to ensure that the horizontal adjustment frame can slide stably horizontally to achieve the adjustment of the spacing between the conveying units, the following technical solution is provided.

[0010] Assembly beams arranged horizontally are fixedly connected to both ends of the processing box. A guiding shaft A arranged horizontally is fixedly connected between the two groups of assembly beams. A guiding sleeve A sleeved outside the guiding shaft A is fixedly connected to the horizontal adjustment frame.

[0011] In some embodiments, to ensure that the vertical adjustment frame can lift and lower stably on the horizontal adjustment frame and the height of the vertical adjustment frame can be adjusted and positioned through the lifting adjustment component, the following technical solution is provided.

[0012] A guiding shaft B arranged vertically is fixedly connected to the vertical adjustment frame. A guiding sleeve B sleeved outside the guiding shaft B is fixedly connected to the horizontal adjustment frame.

[0013] The lifting adjustment component includes a threaded rod and a threaded seat. The threaded rod is fixedly connected to the vertical adjustment frame and is arranged vertically. The threaded seat is rotatably installed on the horizontal adjustment frame and is in screw connection with the threaded rod.

[0014] In some embodiments, to ensure that the transmission component can be in power connection with the spline main shaft, avoid interference from the side wall of the processing box, and at the same time facilitate the adjustment of various components assembled on the processing box and the laying of the output strapping tape on each conveying unit, an operation window is opened on the side wall of the processing box, and the transmission component is arranged in the operation window.

[0015] In some of these embodiments, to ensure that the transmission assembly can be stably installed on the longitudinal adjustment frame and achieve power connection with the spline main shaft and the installation shaft, the following technical solutions are provided.

[0016] A lifting guide groove is formed on the longitudinal adjustment frame. The transmission assembly includes an assembly bracket, a spline sub-shaft, a driving bevel gear A, and a driving bevel gear B. The assembly bracket is slidably installed in the lifting guide groove. The driving bevel gear A is rotatably installed on the assembly bracket and is kept in sliding plug connection with the spline main shaft. The spline sub-shaft is rotatably installed on the assembly bracket and is arranged in the vertical direction. A transmission bevel gear A that meshes with the driving bevel gear A is fixedly connected to the spline sub-shaft. The driving bevel gear B is rotatably installed on the longitudinal adjustment frame and is kept in sliding plug connection with the spline sub-shaft. A transmission bevel gear B that meshes with the driving bevel gear B is fixedly connected to the installation shaft.

[0017] The beneficial effects of the present utility model:

[0018] 1. Flexibility in position adjustment: Different from the traditional fixed-layout idler wheels, the conveying unit in this solution has horizontal and vertical adjustment functions. Through the settings of the horizontal adjustment frame and the longitudinal adjustment frame, the position of the idler wheel can be adjusted in the horizontal and vertical directions according to actual production requirements. This characteristic enables the conveying mechanism to adapt to packing belts of different specifications and requirements, effectively solving the problem that the traditional fixed-layout idler wheels cannot be flexibly adjusted, and ensuring the stability and uniformity of the packing belt during conveying.

[0019] 2. Stable power transmission: In this solution, through the power connection between the transmission assembly and the installation shaft, the stable operation of the idler wheel is ensured. The driving motor fixedly installed outside the processing box transmits power to each group of transmission assemblies through the spline main shaft, realizing the uniform distribution of power. Since the idler wheel can be adjusted according to requirements, the stability of power transmission is significantly improved, avoiding the problem of unstable operation of some idler wheels in the traditional design, thereby improving the overall reliability and efficiency of the conveying system.

[0020] 3. Effective cooling and temperature reduction: Cooling water can be injected into the processing box or an air distribution plate can be assembled, which helps to effectively cool and reduce the temperature of the passing packing belt. This design ensures that the packing belt can be quickly cooled during conveying, with a better shaping effect, and avoids deformation or transmission problems of the packing belt caused by excessive temperature. The configuration of the cooling system improves the accuracy of the production process and the product quality.

[0021] 4. Enhanced production adaptability: Through flexible adjustment and stable power transmission, the conveying mechanism of this solution can adapt to different production environments and requirements. This adaptability enhances the versatility of the production line, enabling it to process various types and specifications of packing belts, and improving the production efficiency and flexibility.

[0022] In summary, by introducing flexible adjustment functions, stable power transmission, and effective cooling designs, the conveying mechanism of this solution overcomes the deficiencies of traditional conveying mechanisms and significantly improves the performance and reliability of the packing belt production line.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-4, A conveying mechanism for a strapping belt production line, including a processing box 1 and multiple groups of conveying units 2 assembled in the processing box 1 and arranged horizontally. The conveying unit 2 includes a horizontal adjustment frame 21, a vertical adjustment frame 22, a mounting shaft 23, a supporting wheel 24, and a transmission assembly 25. The horizontal adjustment frame 21 is movably installed in the processing box 1 and slides horizontally. The vertical adjustment frame 22 is slidably installed on the horizontal adjustment frame 21 and moves up and down vertically. The vertical adjustment frame 22 is associated with the horizontal adjustment frame 21 through a lifting adjustment assembly. The mounting shaft 23 is rotatably installed on the vertical adjustment frame 22, and multiple groups of supporting wheels 24 are uniformly fixed on the mounting shaft 23. The transmission assembly 25 is assembled on the vertical adjustment frame 22 and is in power connection with the mounting shaft 23.

[0030] It also includes a driving motor 3 fixedly installed outside the processing box 1. A spline main shaft 31 arranged horizontally is fixed on the output shaft of the driving motor 3. The spline main shaft 31 is rotatably installed outside the processing box 1, and the spline main shaft 31 is in power connection with each group of transmission assemblies 25.

[0031] The processing box 1 is assembled and welded with steel plates, which can ensure the stable installation of the conveying unit 2, the driving motor 3, and the spline main shaft 31 on it. During the production process of the strapping belt (mostly nylon belt), the strapping belt extruded by the extruder is placed on the supporting wheels 24 in each conveying unit 2, and the driving motor 3 drives the mounting shaft 23 and the supporting wheels 24 in each group of conveying units 2 to rotate stably through the spline main shaft 31 and the transmission mechanism, so as to drive the extruded strapping belt for transmission.

[0032] Cooling water can be injected into the processing box 1 to cool down the passing strapping belt, or a air distribution plate for supplying natural wind is assembled at the bottom of the processing box 1. The blown natural wind can cool down the strapping belt transmitted above, so that the strapping belt is cooled and shaped.

[0033] During the actual production and conveying process of the strapping belt, the distance between each group of conveying units 2 and the installation height of the supporting wheels 24 can be adjusted according to specific conditions. By controlling the horizontal movement of the horizontal adjustment frame 21, the distance between adjacent conveying units 2 can be adjusted. By operating the lifting adjustment assembly to drive the vertical adjustment frame 22 and the supporting wheels 24 thereon to move up and down synchronously, the adjustment of the installation height of the supporting wheels 24 is realized.

[0034] During the horizontal and vertical adjustment process of the conveying unit 2, the power of the driving motor 3 can always be transmitted to the transmission mechanism through the spline main shaft 31, and then the transmission mechanism drives the mounting shaft 23 and the supporting wheels 24 to rotate stably.

[0035] The driving motor 3 adopts a reduction motor, and the output torque is amplified by reducing speed and increasing torque to drive the supporting wheels 24 on each group of conveying units 2 to rotate stably.

[0036] To ensure that the horizontal adjustment frame 21 can slide stably in the horizontal direction to achieve the adjustment of the spacing of the conveying unit 2, the following technical solutions are provided.

[0037] At both ends of the processing box 1, there are horizontally arranged mounting beams 11 fixedly connected. Between the two groups of mounting beams 11, there is a horizontally arranged guide shaft A12 fixedly connected. On the horizontal adjustment frame 21, there is a guide sleeve A211 sleeved on the outside of the guide shaft A12.

[0038] The setting of the mounting beam 11 can ensure the stable erection of the guide shaft A12 in the processing box 1. Through the cooperation of the guide shaft A12 and the guide sleeve A211, it can ensure the stable sliding of the horizontal adjustment frame 21 in the horizontal direction. A radially arranged locking nut can also be screwed onto the guide sleeve A211. After the position adjustment of the horizontal adjustment frame 21 is completed, by screwing the locking nut to abut against the inner guide shaft A12, the positioning of the horizontal adjustment frame 21 is achieved.

[0039] To ensure the stable lifting of the vertical adjustment frame 22 on the horizontal adjustment frame 21 and to adjust and position the height of the vertical adjustment frame 22 through the lifting adjustment assembly, the following technical solutions are provided.

[0040] On the vertical adjustment frame 22, there is a vertically arranged guide shaft B221 fixedly connected. On the horizontal adjustment frame 21, there is a guide sleeve B212 sleeved on the outside of the guide shaft B221.

[0041] The lifting adjustment assembly includes a threaded rod 261 and a threaded seat 262. The threaded rod 261 is fixedly connected to the vertical adjustment frame 22 and is arranged vertically. The threaded seat 262 is rotatably installed on the horizontal adjustment frame 21 and is screwed with the threaded rod 261.

[0042] The combination of the guide shaft B221 and the guide sleeve B212 can ensure the stable lifting of the vertical adjustment frame 22 in the vertical direction. When adjusting the height position of the vertical adjustment frame 22, by rotating the threaded seat 262, the threaded rod 261 can be driven to move up and down, thereby realizing the height adjustment of the vertical adjustment frame 22.

[0043] To ensure that the transmission component 25 can be power-connected to the spline main shaft 31, avoid interference from the side wall of the processing box 1, and at the same time facilitate the adjustment of the various components assembled on the processing box 1 and the erection of the output packing tape on each conveying unit 2, an operation window 13 is opened on the side wall of the processing box 1, and the transmission component 25 is arranged in the operation window 13.

[0044] The setting of the operation window 13 can ensure that the transmission component 25 is power-connected to the outside spline main shaft 31 through the operation window 13, and it is also convenient to adjust the horizontal position and height position of each conveying unit 2, and it is also convenient to erect the packing tape on the idler wheels 24 of each conveying unit 2.

[0045] To ensure that the transmission assembly 25 can be stably installed on the longitudinal adjustment frame 22 and achieve power connection with the spline main shaft 31 and the mounting shaft 23, the following technical solutions are provided.

[0046] The longitudinal adjustment frame 22 is provided with a lifting guide groove 222. The transmission assembly 25 includes an assembly bracket 251, a spline sub-shaft 252, a driving bevel gear A 253, and a driving bevel gear B 254. The assembly bracket 251 is slidably installed in the lifting guide groove 222. The driving bevel gear A 253 is rotatably installed on the assembly bracket 251 and is kept in sliding insertion with the spline main shaft 31. The spline sub-shaft 252 is rotatably installed on the assembly bracket 251 and is arranged in the vertical direction. A transmission bevel gear A 2521 that meshes with the driving bevel gear A 253 is fixedly connected to the spline sub-shaft 252. The driving bevel gear B 254 is rotatably installed on the longitudinal adjustment frame 22 and is kept in sliding insertion with the spline sub-shaft 252. A transmission bevel gear B 231 that meshes with the driving bevel gear B 254 is fixedly connected to the mounting shaft 23.

[0047] The setting of the lifting guide groove 222 enables the assembly bracket 251 to always maintain a specific height during the lifting movement of the longitudinal adjustment frame 22, so that the driving bevel gear A 253 thereon is always kept in sliding insertion with the spline main shaft 31. When the conveying unit 2 adjusts the horizontal position, the power of the spline main shaft 31 can always be transmitted to the driving bevel gear A 253, and then the power is always transmitted to the spline sub-shaft 252 through the transmission bevel gear A 2521.

[0048] During the lifting movement of the longitudinal adjustment frame 22, the spline sub-shaft 252 is always kept in sliding insertion with the driving bevel gear B 254 installed on the longitudinal adjustment frame 22, so that the power is stably transmitted to the driving bevel gear B 254, and then the mounting shaft 23 and the supporting wheel 24 thereon are driven to rotate stably through the transmission bevel gear B 231.
