Description

Technical Field

[0001] This utility model relates to the field of wiper flat wire processing and application technology, and in particular to a wiper flat wire guide wheel structure for a calendering and winding machine. Background Technology

[0002] As the core transmission component of a windshield wiper, the processing precision of the wiper flat wire directly affects the operational stability and service life of the wiper. In the production process of the wiper flat wire, the calendering and winding machine is responsible for conveying and winding the flat wire after calendering, while the guide wheel structure is a key component to ensure the stability and precise positioning of the flat wire during the conveying process. Its performance plays a decisive role in the quality of the final product.

[0003] Existing calender winding machines mostly employ a fixed guide wheel design, making it impossible to flexibly adjust the guide angle and guide spacing according to actual processing needs. This structure struggles to achieve precise guidance when dealing with wiper flat wires of different specifications, or due to equipment installation errors or minor adjustments to the conveying path. This can easily lead to problems such as wire misalignment, jamming, and surface wear, reducing processing accuracy and product yield. Furthermore, uneven force on the flat wire can cause equipment malfunctions, impacting production efficiency. Therefore, this invention proposes a new guide wheel structure for wiper flat wires in a calender winding machine. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wiper flat wire guide wheel structure for a calender take-up machine. Through an adjustable structural design, it can achieve precise control of the guide position of the wiper flat wire, thereby improving guide stability and processing accuracy.

[0005] To solve the above technical problems, the present invention provides a technical solution: a windshield wiper flat wire guide wheel structure for a calender winding machine, including a mounting block installed on the calender winding machine, a positioning wheel assembly being disposed through the interior of the mounting block, a connecting block being bolted to the top of the mounting block, an adjusting frame being movably assembled inside the connecting block, and a guide wheel assembly being fixedly connected to the end face of the adjusting frame by bolts. By adjusting the assembly position of the adjustment frame on the connecting block, the guide wheel assembly connected to its end face is driven to form an adjustable tilt angle relative to the positioning wheel assembly, thereby achieving precise adjustment of the guide position of the wiper flat wire conveyed by the calender take-up machine.

[0006] The present invention is further configured such that: the positioning wheel assembly includes a positioning shaft that passes through the mounting block and is fixed to the mounting block by a nut; a positioning disc is fixedly connected to one end of the outer wall of the positioning shaft; and an adjusting disc is sleeved on one end of the outer wall of the positioning shaft.

[0007] Through the above technical solution, the positioning shaft is fixedly assembled with the mounting block by the nut, providing a stable installation base for the positioning wheel assembly; the positioning plate and the adjusting plate cooperate to form a guide space, wherein the adjusting plate can be finely adjusted along the axial direction of the positioning shaft, thereby adapting to the positioning requirements of different specifications of wiper flat wires, ensuring that the flat wires maintain a basic positioning posture during transportation and avoiding lateral deviation.

[0008] The present invention is further configured such that: the other side of the adjusting plate is fastened to the outer wall of the positioning shaft by bolts, and a guide ring is fixedly connected at the middle position of the opposite wall of the adjusting plate and the positioning plate, and the guide ring is sleeved on the outer wall of the positioning shaft.

[0009] Through the above technical solution, the bolt fastening method can lock the adjustment position of the adjustment plate on the positioning shaft to prevent it from loosening during equipment operation; the guide ring is located between the positioning plate and the adjustment plate, forming an annular guide channel. When the wiper flat cable passes through this channel, the inner wall of the guide ring can play a circumferential limiting role on the flat cable, further improving the stability of the basic positioning, while reducing the frictional loss between the flat cable and the positioning wheel assembly.

[0010] The present invention is further configured such that: the adjusting frame includes an adjusting shaft inserted into the connecting block and rotatably adjustable; a fixed cylinder is fixedly connected to the end face of the adjusting shaft; an adjusting rod is inserted into the inside of the fixed cylinder; and the adjusting rod is fastened to the inside of the fixed cylinder by bolts; the end face of the adjusting rod is bolted to the guide wheel assembly.

[0011] Through the above technical solution, the adjusting shaft can rotate around its own axis inside the connecting block, thereby driving the fixed cylinder and the adjusting rod to rotate synchronously, realizing the adjustment of the tilt angle of the guide wheel assembly; the adjusting rod can be extended and retracted along the axial direction of the fixed cylinder, and the length can be locked by bolt fastening, which can change the distance between the guide wheel assembly and the positioning wheel assembly to adapt to different conveying path requirements; through the combination of angle adjustment and length adjustment, multi-dimensional precise control of the position of the guide wheel assembly can be achieved, ensuring that the guiding angle and guiding distance of the wiper flat wire reach the optimal state.

[0012] The present invention is further configured such that: the guide wheel assembly includes a mounting shaft mounted on an adjusting rod, a guide disc and a limiting disc are sleeved on the outer wall of the mounting shaft, and multiple guide blocks are uniformly fixedly connected to the opposite walls of the guide disc and the limiting disc in the circumferential direction.

[0013] Through the above technical solution, the mounting shaft provides a mounting carrier for the guide disc, limiting disc, and guide blocks, ensuring stable assembly of each component; multiple evenly distributed guide blocks form a ring-shaped guide structure, which cooperates with the guide ring of the positioning wheel assembly to form a secondary guide and limit from the downstream of the wiper flat wire; when the guide block contacts the flat wire, it can reduce the contact area and reduce frictional resistance through its own structure, while the evenly distributed circumference design can ensure that the flat wire is subjected to balanced force, avoid excessive local pressure that could cause deformation of the flat wire, and further improve the stability and accuracy of the guide and conveying.

[0014] The present invention is further configured such that all of the guide blocks are cylindrical structures and have the same axial length as the guide ring.

[0015] Through the above technical solution, the cylindrical guide block has a smooth curved surface, which causes rolling friction when in contact with the wiper blade flat wire, thus minimizing friction loss and avoiding scratches on the surface of the flat wire. The design that the axial length of the guide block and the guide ring are equal ensures that the wiper blade flat wire is always guided and limited by the guide ring and the guide block throughout the entire guide stroke, avoiding local situations where there is no guide constraint and ensuring the consistency of guide accuracy.

[0016] The present invention is further configured such that the limiting disc is fastened to one end of the mounting shaft by a nut and abuts against the end face of multiple guide blocks.

[0017] Through the above technical solution, the nut fastening method can firmly fix the limiting plate on the mounting shaft. The limiting plate abuts and limits the end face of the guide block, preventing the guide block from moving axially along the mounting shaft during equipment operation, and ensuring the stability and reliability of the annular guide structure formed by the guide block. At the same time, this fixing method is easy to disassemble and maintain, and guide blocks of different specifications can be replaced according to actual use needs, improving the versatility and practicality of the structure.

[0018] The beneficial effects of this utility model are as follows: 1. The wiper flat wire guide wheel structure of the calender winding machine proposed in this utility model realizes the dual limiting guidance of the wiper flat wire through the cooperation of the positioning wheel assembly and the guide wheel assembly. Combined with the multi-dimensional adjustment function of the adjustment frame, it can accurately adapt to different specifications of flat wire and different conveying path requirements, effectively solving the problem that the traditional fixed guide structure cannot be flexibly adjusted, and greatly improving the guiding accuracy and processing adaptability. 2. The wiper flat wire guide wheel structure of the calendering take-up machine proposed in this utility model reduces friction loss during flat wire conveying through the design of guide ring and cylindrical guide block, avoids flat wire deviation, jamming and deformation, and improves product qualification rate; at the same time, the components are fastened with bolts and nuts, which makes disassembly and maintenance convenient, reduces equipment maintenance costs and downtime, and ensures production efficiency.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] like Figures 1-5 As shown, a wiper flat wire guide wheel structure for a calender take-up machine includes a mounting block 1 installed on the calender take-up machine. A positioning wheel assembly 2 is disposed inside the mounting block 1. The positioning wheel assembly 2 includes a positioning shaft 21 that passes through the mounting block 1 and is fixed to the mounting block 1 by a nut. A positioning disc 22 is fixedly connected to one end of the outer wall of the positioning shaft 21, and an adjusting disc 23 is sleeved on one end of the outer wall of the positioning shaft 21. The positioning shaft 21 is fixedly assembled with the mounting block 1 by a nut, providing a stable mounting base for the positioning wheel assembly 2. The positioning disc 22 and the adjusting disc 23 cooperate to form a guide space, wherein the adjusting disc 23 can be finely adjusted along the axial direction of the positioning shaft 21 to adapt to the positioning requirements of wiper flat wires of different specifications, ensuring that the flat wire maintains its basic positioning posture during the conveying process and avoiding lateral deviation. The other side of the adjusting disc 23 is fastened to the outer wall of the positioning shaft 21 by bolts. A guide ring 231 is fixedly connected to the middle of the opposite wall of the adjusting disc 23 and the positioning disc 22. The guide ring 231 is sleeved on the outer wall of the positioning shaft 21. The bolt fastening method can lock the adjustment position of the adjusting disc 23 on the positioning shaft 21 to prevent it from loosening during equipment operation. The guide ring 231 is located between the positioning disc 22 and the adjusting disc 23, forming an annular guide channel. When the wiper flat wire passes through this channel, the inner wall of the guide ring 231 can play a circumferential limiting role on the flat wire, further improving the stability of the basic positioning, and reducing the frictional loss between the flat wire and the positioning wheel assembly 2.

[0023] like Figure 6 As shown, the top of the mounting block 1 is bolted to a connecting block 3. An adjusting frame 4 is movably mounted inside the connecting block 3. The adjusting frame 4 includes an adjusting shaft 41 inserted into the connecting block 3 and rotatably adjustable. A fixed cylinder 42 is fixedly connected to the end face of the adjusting shaft 41. An adjusting rod 43 is inserted inside the fixed cylinder 42 and bolted to it. The end face of the adjusting rod 43 is bolted to the guide wheel assembly 5. The adjusting shaft 41 can rotate around its own axis inside the connecting block 3, thereby driving the fixed cylinder 42 and the adjusting rod 43 to rotate synchronously, thus adjusting the tilt angle of the guide wheel assembly 5. The adjusting rod 43 can extend and retract along the axial direction of the fixed cylinder 42, and its length is locked by bolt fastening, allowing for changes in the distance between the guide wheel assembly 5 and the positioning wheel assembly 2 to adapt to different conveying path requirements. Through the combination of angle adjustment and length adjustment, multi-dimensional precise control of the guide wheel assembly 5's position can be achieved, ensuring that the guiding angle and guiding distance of the wiper cable reach the optimal state.

[0024] like Figure 5 As shown, the end face of the adjusting frame 4 is fixedly connected to the guide wheel assembly 5 by bolts. The guide wheel assembly 5 includes a mounting shaft 51 mounted on the adjusting rod 43. The outer wall of the mounting shaft 51 is sleeved with a guide disc 52 and a limiting disc 54. Multiple guide blocks 53 are evenly fixedly connected to the opposite walls of the guide disc 52 and the limiting disc 54 in the circumferential direction. The mounting shaft 51 provides a mounting carrier for the guide disc 52, the limiting disc 54 and the guide blocks 53, ensuring the stable assembly of each component. Multiple evenly distributed guide blocks 53 form a ring guide structure, which cooperates with the guide ring 231 of the positioning wheel assembly 2 to form a secondary guide and limit from the downstream of the wiper flat wire. When the guide block 53 contacts the flat wire, it can reduce the contact area and reduce frictional resistance through its own structure. At the same time, the evenly distributed circumferential design can ensure that the flat wire is subjected to balanced force, avoid excessive local pressure that causes deformation of the flat wire, and further improve the stability and accuracy of the guide and conveying. Multiple guide blocks 53 are cylindrical in structure and have the same axial length as the guide ring 231. The cylindrical guide blocks 53 have smooth curved surfaces and roll friction when in contact with the wiper blade flat wire, which can minimize friction loss and avoid scratching the surface of the flat wire. The design that the guide blocks 53 and the guide ring 231 have the same axial length ensures that the wiper blade flat wire is always guided and limited by the guide ring 231 and the guide blocks 53 throughout the entire guide stroke, avoiding the situation of no local guidance constraint and ensuring the consistency of guidance accuracy.

[0025] The limiting plate 54 is fastened to one end of the mounting shaft 51 by a nut and abuts against the end faces of multiple guide blocks 53. The nut fastening method can firmly fix the limiting plate 54 to the mounting shaft 51. The limiting plate 54 abuts against and limits the end faces of the guide blocks 53 to prevent the guide blocks 53 from moving axially along the mounting shaft 51 during equipment operation, ensuring that the annular guide structure formed by the guide blocks 53 is stable and reliable. At the same time, this fixing method is easy to disassemble and maintain, and guide blocks 53 of different specifications can be replaced according to actual use needs, improving the versatility and practicality of the structure. By adjusting the assembly position of the adjustment frame 4 on the connecting block 3, the guide wheel assembly 5 connected to its end face is driven to form an adjustable tilt angle relative to the positioning wheel assembly 2, thereby achieving precise adjustment of the guide position of the calender winding machine for conveying the wiper flat wire.

[0026] In use, this invention first adjusts the positioning wheel assembly 2 by adjusting the adjusting disc 23 along the positioning shaft 21, forming a basic guide channel adapted to the specifications of the wiper flat cable, thus achieving initial positioning of the flat cable. Then, the tilt angle of the guide wheel assembly 5 is adjusted by rotating the adjusting shaft 41 of the adjusting frame 4, and the distance between the guide wheel assembly 5 and the positioning wheel assembly 2 is adjusted by extending and retracting the adjusting rod 43, thus completing the precise calibration of the guide position. When the wiper flat cable is being transported, it passes through the channel formed by the guide ring 231 of the positioning wheel assembly 2 and the guide block 53 of the guide wheel assembly 5 in sequence. Under the double limiting and guiding action, it is stably transported along the preset path, ensuring guiding accuracy and stability.
