Description

Technical Field

[0001] This utility model relates to the field of rubber-impregnated line cutting technology, specifically a cutting mechanism for producing rubber-impregnated lines for brake hoses. Background Technology

[0002] Motor vehicle brake hoses are a crucial component of the automotive braking system. Their main function is to transmit braking force to the brake mechanism of the wheels. The rubber impregnation line is a production line used to produce motor vehicle brake hoses. Through the rubber impregnation process, rubber material is coated onto the skeleton material to form the inner or outer layer of the hose. During the production process of the rubber impregnation line, the hose is cut according to the length of the impregnation line.

[0003] For example, patent CN222553648U discloses a cutting mechanism for an impregnation production line, including support legs. A first conveyor table and a second conveyor table are respectively arranged on the upper surface of the support legs. A cutting mechanism is arranged between the first and second conveyor tables. The cutting mechanism includes an introduction frame, an opening, a narrow section, a movable sleeve, a movable column, a loading plate, an extension, a narrow cutter, an upper channel, a lower channel, a servo cylinder, and a top plate. Through the arrangement of the narrow cutter on the loading plate and the upper and lower channels, the cutting mechanism allows the impregnated material to be cut. While the process continues, the material is smoothly transported through these channels, greatly improving production efficiency. However, the dip-impregnation line needs to be stretched and taut during the cutting process to maintain the flatness and precision of the cutting. After cutting, the remaining dip-impregnation line is no longer taut on the cutting mechanism and needs to be manually stretched and adjusted to correspond to its position below the cutting mechanism. This is not conducive to the continuous and rapid cutting of the dip-impregnation line. In addition, motor vehicle brake hoses come in different sizes, and the required cutting length of the dip-impregnation line varies. Some existing cutting mechanisms are not convenient for adjusting the cutting length of the dip-impregnation line at a fixed distance, which is not conducive to diversified production of dip-impregnation lines.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing glue-dipping line cutting mechanism. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting mechanism for producing dipped lines for brake hoses, in order to solve the problem mentioned in the background art that the dipped lines need to be stretched and straightened during the cutting process to maintain the flatness and accuracy of the cutting process, and the remaining dipped lines after cutting are no longer straight on the cutting mechanism, requiring manual stretching and adjustment of the dipped lines to correspond to their position below the cutting mechanism, which is not conducive to the continuous and rapid cutting process of the dipped lines.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting mechanism for producing impregnated rubber lines for brake hoses, comprising a cutting table and a blade mounted on the cutting table for cutting the impregnated rubber lines. A support frame is fixedly mounted on the cutting table, and a take-up wheel for releasing the impregnated rubber lines is rotatably mounted on the support frame. A guide wheel for limiting the cutting direction of the impregnated rubber lines is also mounted on the support frame. A reciprocating conveying mechanism for conveying the impregnated rubber lines is provided on the cutting table, and a tensioning adjustment mechanism for adjusting the cutting length of the impregnated rubber lines is also provided on the cutting table. Both the conveying mechanism and the tensioning adjustment mechanism are provided with clamping components for clamping and limiting the impregnated rubber lines.

[0007] Preferably, the feeding mechanism includes two sets of drive shafts rotatably mounted on the cutting table, and drive belts are sleeved on the outside of the two sets of drive shafts; a servo motor is mounted on the outside of the cutting table, and the output end of the servo motor is coaxially connected to one of the drive shafts.

[0008] Preferably, two positioning supports are fixed on the transmission belt, and a lifting cylinder for adjusting the height of the clamping assembly is fixedly installed on the positioning supports.

[0009] Preferably, the tension adjustment mechanism includes an electric slide rail fixed to the inner wall of the cutting table, and an electric slide block for adjusting the distance between the clamping assembly and the blade is slidably mounted on the electric slide rail.

[0010] Preferably, the clamping assembly includes a fixed bracket fixed to the electric slide and the output end of the lifting cylinder, and a retaining ring is fixedly installed on the fixed bracket; a sliding frame is slidably sleeved on the fixed bracket, a movable bracket is fixedly connected to the sliding frame, and a retaining pin is fixedly installed on the movable bracket; a telescopic cylinder is fixedly installed on the fixed bracket, and the output end of the telescopic cylinder is fixedly connected to the movable bracket.

[0011] Preferably, the locking pins and locking rings are distributed laterally in correspondence, and the lateral movement of the locking pins engages with the locking rings.

[0012] Preferably, the retaining ring and retaining post in the clamping assembly of the lifting cylinder are located above the telescopic cylinder, and the retaining ring and retaining post in the clamping assembly of the electric slide are located below the telescopic cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the cutting mechanism for producing the dipped line for brake hoses can autonomously guide and release the dipped line through the winding wheel and guide wheel, maintaining a stable output of the dipped line for continuous cutting. The dipped line is set below the blade, and the cutting of the dipped line is completed when the blade rotates.

[0014] Furthermore, the cutting table is equipped with a reciprocating conveyor for the dip line. A servo motor controls the rotation of the drive shaft, which drives the belt to move back and forth. During the reciprocating movement of the belt, the positioning support moves synchronously. The corresponding clamping components on the positioning support can clamp the dip line and keep the dip line stretched and positioned below the blade for continuous cutting of the dip line.

[0015] The cutting table is also equipped with a tension adjustment mechanism to adjust the cutting length of the dip line. This mechanism controls the electric slide to move laterally on the electric slide rail. One side of the electric slide can adjust the cutting length of the dip line, while the other side can keep the dip line taut and stretched below the blade, assisting in the rapid cutting of the dip line.

[0016] Furthermore, both the delivery mechanism and the tensioning adjustment mechanism are equipped with clamping components for clamping and restricting the impregnation line. The telescopic cylinder controls the lateral movement of the moving bracket, which in turn drives the clamping pin to move laterally in sync. The position of the clamping pin on the side of the clamping ring is adjusted to clamp and restrict the processing position of the impregnation line.

[0017] The positions of the pins and rings in the clamping components of the transfer mechanism and tension adjustment mechanism correspond to each other, ensuring that the limited impregnation line can be clamped in the same axial direction to assist in its cutting process.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1: Please refer to Figures 1-7 The present invention provides the following technical solution: a cutting mechanism for producing impregnated rubber lines for brake hoses, comprising a cutting table 1 and a blade 2 mounted on the cutting table 1 for cutting the impregnated rubber lines. A support frame 3 is fixedly mounted on the cutting table 1, and a winding wheel 4 for releasing the impregnated rubber lines is rotatably mounted on the support frame 3. A guide wheel 5 for limiting the cutting direction of the impregnated rubber lines is also mounted on the support frame 3. A reciprocating conveying mechanism for conveying the impregnated rubber lines is provided on the cutting table 1, and a tensioning adjustment mechanism for adjusting the cutting length of the impregnated rubber lines is also provided on the cutting table 1. Both the conveying mechanism and the tensioning adjustment mechanism are provided with clamping components for clamping and limiting the impregnated rubber lines.

[0028] The feeding mechanism includes two sets of drive shafts 6 rotatably mounted on the cutting table 1, and drive belts 7 are sleeved on the outside of the two sets of drive shafts 6; a servo motor 8 is mounted on the outside of the cutting table 1, and the output end of the servo motor 8 is coaxially connected to one of the drive shafts 6.

[0029] Two positioning supports 9 are fixed on the transmission belt 7, and a lifting cylinder 10 for adjusting the height of the clamping assembly is fixedly installed on the positioning supports 9.

[0030] The dipped wire is wound around the outside of the take-up reel 4. The take-up reel 4 is rotated by the motor to release the dipped wire. The released dipped wire is guided outward by the guide wheel 5. The output dipped wire is stretched and set below the blade 2 by the clamping assembly. The motor controls the blade 2 to rotate, and the blade 2 quickly cuts the dipped wire.

[0031] The clamping components on both sides of the blade 2 tighten and stretch the dip line below the blade 2. The two sets of clamping components above the drive belt 7 are positioned on the side of the blade 2 closest to the take-up reel 4 before cutting. These clamping components assist in clamping the outside of the dip line. After cutting, the dip line on one side is disconnected from the dip line in the output direction of the take-up reel 4. At this point, the remaining dip line is no longer stretched below the blade 2. The lifting cylinder 10 then controls the clamping components to move downwards to avoid the lowest position of the blade 2. The servo motor 8 controls the drive shaft 6 to rotate, which in turn drives the drive belt 7 to move. The positioning support 9 fixed on the drive belt 7 moves synchronously with this rotation. This causes the two sets of clamping components on the transmission belt 7 to move towards the clamping components fixed on the electric slide 18 on the other side. The movement of the two sets of clamping components on the transmission belt 7 corresponds to the positions on both sides of the clamping components on the electric slide 18. The operating lifting cylinder 10 controls the clamped impregnated line to move upward, so that the clamping components on the electric slide 18 can re-clamp and limit the impregnated line, so that the impregnated line is re-clamped and stretched below the blade 2. The height of the clamping components on the transmission belt 7 is lowered and reset. This process is repeated to continuously clamp and transport the impregnated line, so that the impregnated line can be continuously stretched and cut, improving the cutting efficiency.

[0032] Example 2: Based on Example 1, a tension adjustment mechanism is also disclosed, the specific structure of which is as follows: The tension adjustment mechanism includes an electric slide rail 17 fixed to the inner side wall of the cutting table 1, and an electric slide block 18 for adjusting the distance between the clamping assembly and the blade 2 is slidably installed on the electric slide rail 17.

[0033] The clamping assembly includes a fixed bracket 11 fixed to the electric slide 18 and the output end of the lifting cylinder 10, and a retaining ring 12 fixedly installed on the fixed bracket 11; a sliding frame 13 is slidably sleeved on the fixed bracket 11, a movable bracket 14 is fixedly connected to the sliding frame 13, and a retaining post 15 is fixedly installed on the movable bracket 14; a telescopic cylinder 16 is fixedly installed on the fixed bracket 11, and the output end of the telescopic cylinder 16 is fixedly connected to the movable bracket 14.

[0034] The locking pin 15 and the locking ring 12 are distributed laterally in correspondence, and the locking pin 15 moves laterally to engage with the locking ring 12.

[0035] The retaining ring 12 and retaining post 15 in the clamping assembly of the lifting cylinder 10 are located above the telescopic cylinder 16, while the retaining ring 12 and retaining post 15 in the clamping assembly of the electric slide block 18 are located below the telescopic cylinder 16.

[0036] The telescopic cylinder 16 pushes the movable bracket 14 to move, and the movable bracket 14 controls the locking pin 15 to move synchronously, adjusting the distance between the locking pin 15 and the locking ring 12 to keep the locking pin 15 and the locking ring 12 in a state of moving apart or moving to clamp the dipped line.

[0037] According to the required length of the dipped line, adjust the distance between the clamping component on the side away from the take-up wheel 4 and the blade 2, control the electric slide 18 to engage and slide on the electric slide rail 17, thereby adjusting the position of the clamping component on the electric slide 18 corresponding to the side of the blade 2. After clamping the dipped line in the clamping components on both sides of the blade 2, move the electric slide 18 on the other side to keep the dipped line taut and stretched between the clamping components on the left and right sides of the blade 2, thereby improving the accuracy of the dipped line processing and the flatness of the cut.
