Description

Technical Field

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

[0002] As a core functional component of windshield wipers, the processing precision of the wiper flat wire directly affects the wiping performance and service life of the wipers. In the production process of wiper flat wires, the calendering process is a crucial step that determines key parameters such as cross-sectional dimensions and flatness. After calendering, the wiper flat wire needs to be guided and transported into subsequent processing steps.

[0003] However, existing calendering production lines have significant technical problems in the guiding and conveying process: the calendered wiper flat wires need to be continuously pulled out to achieve continuous production, but since the cycle time of subsequent processing is difficult to be completely synchronized with the calendering output speed, the wiper flat wires are easily pulled out excessively, which leads to the wiper flat wires accumulating and bending in the conveying path. This accumulation and bending not only affects the positioning accuracy of subsequent processing, but may also cause scratches, deformation and other damage to the surface of the wiper flat wires during the pulling process, seriously affecting product quality and production efficiency. Therefore, this utility model proposes a wiper flat wire guiding component for calendering production lines. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a wiper flat wire guide assembly for a calendering production line, so as to solve the problem that the wiper flat wire is easy to accumulate, bend and be damaged during the existing guiding and transmission process, and to achieve stable guidance and adaptive adjustment of the calendered wiper flat wire.

[0005] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a wiper flat wire guide assembly for a calendering production line is provided, including guide roller A and guide roller B. The two ends of guide roller A and guide roller B are symmetrically and rotatably connected to a mounting frame, and the mounting frame is used to stably fix guide roller A and guide roller B at the outlet of the calendering equipment. One end of the mounting frame is connected to an adaptation component, and the adaptation component is equipped with an adaptation roller that cooperates with guide roller A and guide roller B, so as to use the adaptation component to carry the adaptation roller to adjust the wiper flat wire after calendering.

[0006] The present invention is further configured such that: the inner walls of the guide roller A and the guide roller B are respectively rotatably connected to the positioning shaft A and the positioning shaft B, and both ends of the positioning shaft A and the positioning shaft B are bolted to the mounting brackets at both ends.

[0007] Through the above technical solution, positioning shaft A and positioning shaft B provide stable rotational support for guide roller A and guide roller B, respectively. The bolt connection between their two ends and the mounting bracket ensures the firmness of guide roller A and guide roller B installation and facilitates subsequent disassembly and maintenance. At the same time, the bolt connection allows for fine adjustment of the positioning shaft installation position, ensuring that the axes of guide roller A and guide roller B are parallel and guaranteeing the straightness of the wiper flat wire transmission.

[0008] The present invention is further configured such that: one end of the mounting bracket is fixedly connected to a mounting block, and the other end is provided with a connecting part A and a connecting part B; the two ends of the positioning shaft A and the positioning shaft B are respectively mounted on the connecting part A and the connecting part B, and a reinforcing rod is sleeved on both the positioning shaft A and the positioning shaft B near their two ends.

[0009] Through the above technical solution, the mounting block is used to realize the rapid docking and installation of the entire guide assembly with the outlet of the calendering equipment, thereby improving the assembly efficiency of the assembly; the connecting part A and the connecting part B provide a precise mounting and positioning surface for the positioning shaft A and the positioning shaft B, ensuring the relative position accuracy of the two guide rollers; the reinforcing rod is sleeved at the position near both ends of the positioning shaft, which can enhance the deformation resistance of the positioning shaft, avoid bending of the positioning shaft due to long-term stress, and thus ensure the rotational stability of the guide rollers.

[0010] The present invention is further configured such that: the adaptation component includes a rotating rod rotatably connected to the positioning shaft B, a limiting post is inserted into the outer wall of the rotating rod near the positioning shaft B, a locking post is fixedly connected to the outer wall of the rotating rod near the adaptation roller, and a tension spring is engaged with the outer wall of the locking post.

[0011] Through the above technical solution, the rotating rod, with the positioning shaft B as the rotation center, can drive the adapting roller to adjust its angle, thereby achieving adaptive pressing of the wiper cable; the limiting post, pressed against the top of the connecting part B, can limit the maximum rotation angle of the rotating rod and prevent the adapting roller from excessively squeezing the wiper cable and causing damage; the locking post provides a stable connection point for the tension spring, and the elastic tension of the tension spring can keep the rotating rod in the direction of the guide roller A, ensuring that the adapting roller is always in contact with the wiper cable.

[0012] The present invention is further configured such that the end face of the limiting post extends to the outer wall of the mounting frame and abuts against the top of the connecting part B.

[0013] Through the above technical solution, the tight fit between the limiting post and the top of the connecting part B forms a mechanical limiting structure, which can accurately control the initial position and maximum swing amplitude of the rotating rod, and prevent the gap between the adapting roller and the guide roller A from being too small due to excessive tension of the spring or external impact, thereby avoiding excessive compression of the wiper flat wire during transmission.

[0014] The present invention is further configured such that the end of the tension spring away from the locking post is engaged with the end face of the connecting part A.

[0015] Through the above technical solution, the two ends of the tension spring are respectively connected to the locking post and the connecting part A, forming a stable elastic tension structure, so that the rotating rod is always subjected to a tension towards the connecting part A; when the wiper flat wire tends to pile up, its pressure on the adapting roller will overcome the tension of the tension spring, pushing the rotating rod to swing to increase the transmission path space and avoid pile-up bending; when the pulling speed increases, the tension of the tension spring will drive the adapting roller to reset, re-press the wiper flat wire, and ensure the tension of transmission.

[0016] The present invention is further configured such that: the inner wall of the adapting roller is rotatably connected to a positioning shaft C, and the two ends of the positioning shaft C are respectively rotatably connected to the rotating rods at both ends; the outer walls of the guide roller A, guide roller B and adapting roller are all provided with multiple arc-shaped grooves at equal intervals along the length direction.

[0017] Through the above technical solution, the positioning shaft C provides rotational support for the adapting roller, enabling it to rotate synchronously with the transmission of the wiper flat wire, reducing sliding friction between the two and preventing scratches on the surface of the wiper flat wire; the arc-shaped grooves on the outer walls of the guide roller A, guide roller B and adapting roller are adapted to the cross-sectional shape of the wiper flat wire, which can accurately limit the wiper flat wire and prevent it from shifting left or right during transmission. At the same time, the design of multiple arc-shaped grooves can meet the simultaneous guidance and transmission of multiple wiper flat wires, improving production efficiency.

[0018] The beneficial effects of this utility model are as follows: 1. The wiper flat wire guide assembly for calendering production line proposed in this utility model, through the cooperation of guide roller A, guide roller B and adapting roller, combined with the elastic adaptive structure of the adapting assembly, can effectively alleviate the problem of accumulation and bending during the pull-out of wiper flat wire: when the pull-out is excessive, the adapting roller can swing with the rotating rod to release space; when the pull-out speed increases, the tension spring drives the adapting roller to reset and tighten, avoiding damage to the wiper flat wire due to accumulation or excessive tension, and significantly improving the product qualification rate; 2. The wiper flat wire guide assembly for a calendering production line proposed in this utility model, through the design of the guide roller and the arc-shaped groove on the outer wall of the adaptation roller, not only achieves precise positioning of the wiper flat wire and prevents transmission deviation, but also adapts to the simultaneous transmission of multiple flat wires, improving production efficiency; at the same time, the bolt connection between the positioning shaft and the mounting frame, the setting of the reinforcing rod and other structures ensure the installation firmness and operation stability of the assembly, and extend its service life.

[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 1-4 As shown, a wiper flat wire guide assembly for a calendering production line includes a guide roller A1 and a guide roller B2. Positioning shafts A11 and B21 are rotatably connected through the inner walls of guide rollers A1 and B2, respectively. Both ends of positioning shafts A11 and B21 are bolted to mounting brackets 4 at both ends. Positioning shafts A11 and B21 provide stable rotational support for guide rollers A1 and B2, respectively. The bolted connection between their ends and the mounting brackets 4 ensures the secure installation of guide rollers A1 and B2 and facilitates subsequent disassembly and maintenance. Simultaneously, the bolted connection allows for fine-tuning of the positioning shaft installation position, ensuring the parallelism of the axes of guide rollers A1 and B2 and guaranteeing the straightness of the wiper flat wire transmission.

[0023] like Figure 5As shown, guide rollers A1 and B2 are symmetrically rotatably connected to mounting brackets 4 at both ends. The mounting brackets 4 stably fix guide rollers A1 and B2 at the outlet of the calendering equipment. One end of the mounting bracket 4 is fixedly connected to a mounting block 41, and the other end is provided with connecting parts A42 and B43. The two ends of positioning shafts A11 and B21 are respectively mounted on connecting parts A42 and B43. Reinforcing rods 44 are sleeved near both ends of positioning shafts A11 and B21. The mounting block 41 enables rapid docking and installation of the entire guide assembly with the outlet of the calendering equipment, improving assembly efficiency. Connecting parts A42 and B43 provide precise mounting surfaces for positioning shafts A11 and B21, ensuring the relative positional accuracy of the two guide rollers. The reinforcing rods 44, sleeved near the ends of the positioning shafts, enhance the positioning shafts' resistance to deformation, preventing bending due to long-term stress and thus ensuring the rotational stability of the guide rollers.

[0024] like Figure 4 and Figure 5 As shown, one end of the mounting bracket 4 is connected to an adaptation component 5, and the adaptation component 5 is equipped with an adaptation roller 3 that cooperates with the guide rollers A1 and B2, so as to adjust the wiper flat wire after calendering by using the adaptation component 5 to carry the adaptation roller 3. The adaptation component 5 includes a rotating rod 51 rotatably connected to the positioning shaft B21. A limit post 52 is inserted into the outer wall of the rotating rod 51 near the positioning shaft B21. A locking post 53 is fixedly connected to the outer wall of the rotating rod 51 near the adaptation roller 3, and the outer wall of the locking post 53 is engaged. With a tension spring 54 attached, the rotating rod 51 rotates around the positioning shaft B21, which can drive the adapting roller 3 to adjust its angle, thus achieving adaptive pressing of the wiper cable. The limiting post 52 abuts against the top of the connecting part B43, which can limit the maximum rotation angle of the rotating rod 51 and prevent the adapting roller 3 from excessively squeezing the wiper cable and causing damage. The locking post 53 provides a stable connection point for the tension spring 54. The elastic tension of the tension spring 54 can keep the rotating rod 51 in the direction of the guide roller A1 with a preload, ensuring that the adapting roller 3 is always in contact with the wiper cable. The end face of the limiting post 52 extends to the outer wall of the mounting bracket 4 and abuts against the top of the connecting part B43. The abutting fit between the limiting post 52 and the top of the connecting part B43 forms a mechanical limiting structure, which can accurately control the initial position and maximum swing amplitude of the rotating rod 51, and prevent the gap between the adapting roller 3 and the guide roller A1 from being too small due to excessive tension of the tension spring 54 or external impact, thereby avoiding excessive compression of the wiper flat wire during transmission. One end of the tension spring 54 away from the locking post 53 is engaged with the end face of the connecting part A42. The two ends of the tension spring 54 are connected to the locking post 53 and the connecting part A42 respectively, forming a stable elastic tension structure, so that the rotating rod 51 is always subjected to a tension towards the connecting part A42. When the wiper wire tends to pile up, its pressure on the adapting roller 3 will overcome the tension of the tension spring 54, pushing the rotating rod 51 to swing to increase the transmission path space and avoid pile-up and bending. When the pulling speed increases, the tension of the tension spring 54 will drive the adapting roller 3 to reset and re-press the wiper wire to ensure the tension of the transmission.

[0025] like Figure 4 As shown, a positioning shaft C31 is rotatably connected through the inner wall of the adapting roller 3, and the two ends of the positioning shaft C31 are rotatably connected to the rotating rods 51 at both ends. The outer walls of the guide rollers A1, B2, and adapting roller 3 are all equidistantly provided with multiple arc-shaped grooves along their length. The positioning shaft C31 provides rotational support for the adapting roller 3, enabling it to rotate synchronously with the transmission of the wiper flat wire, reducing sliding friction between the two and preventing scratches on the surface of the wiper flat wire. The arc-shaped grooves on the outer walls of the guide rollers A1, B2, and adapting roller 3 are adapted to the cross-sectional shape of the wiper flat wire, which can accurately limit the position of the wiper flat wire and prevent it from shifting left or right during transmission. At the same time, the design of multiple arc-shaped grooves can meet the simultaneous guidance and transmission of multiple wiper flat wires, improving production efficiency.

[0026] In use, the assembly is fixed to the outlet of the calendering equipment by the mounting block 41 of the mounting bracket 4. The positioning shafts A11 and B21 cooperate with the connecting part A42, the connecting part B43 and the reinforcing rod 44 respectively to keep the guide rollers A1 and B2 in a stable and parallel rotational state. The calendered wiper wire passes between the guide roller A1 and the adapting roller 3 and outside the guide roller B2. In the adapting assembly 5, the rotating rod 51 uses the positioning shaft B21 as a fulcrum and is driven by the preload of the tension spring 54 and the connecting part A42. The adaptive roller 3 presses the flat wire, and the limiting post 52 abuts against the connecting part B43 to limit the excessive swing of the rotating rod 51. When the flat wire is pulled too much and tends to pile up, its thrust on the adaptive roller 3 overcomes the tension of the tension spring 54, causing the rotating rod 51 to swing, increasing the transmission space and preventing bending. When the pulling speed increases, the tension spring 54 drives the adaptive roller 3 to reset and keep the flat wire taut. At the same time, the arc-shaped groove on the outer wall of the guide roller A1, guide roller B2 and adaptive roller 3 realizes the flat wire limit. The three rotate synchronously to reduce friction, and finally realize the stable guidance and adaptive adjustment of the flat wire.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
