Description

Technical Field

[0001] This application relates to the field of automotive sealing strip manufacturing technology, and in particular to a traction machine for manufacturing automotive sealing components. Background Technology

[0002] In the production process of automotive seals, the traction machine is a key piece of equipment to ensure continuous forming and dimensional stability of the seals. It needs to achieve stable clamping and precise conveying of the sealing strip blank to meet the processing requirements of subsequent cutting, vulcanization and other processes. Existing automotive seal traction machines generally have the following problems: First, the clamping force adjustment of the upper and lower conveying components is not flexible enough to adapt to sealing strips with different cross-sectional sizes and hardness. It is easy to cause damage to the surface of the seal due to excessive clamping, or slippage and conveying deviation due to excessive clamping. Second, the limiting mechanism of the conveying path has poor adaptability and lacks flexible adjustable lateral and longitudinal limiting structures. The sealing strip is prone to deviation and warping during feeding and discharging, affecting the straightness and dimensional accuracy of the product. Third, during the operation of the equipment, it is difficult for operators to observe the internal clamping and traction status in real time, and the degree of automation control is low. Frequent manual adjustment of parameters is required, resulting in low production efficiency and poor product consistency. Therefore, there is an urgent need to design a traction machine for the production of automotive seals that is flexible in clamping and adjustment, precise in positioning, can be observed in real time, and has a high degree of automation, in order to solve the technical problems of insufficient conveying stability, poor adaptability, and inconvenient operation of existing equipment, and to ensure the quality and efficiency of seal production. Utility Model Content

[0003] In order to overcome the problems existing in the prior art, this application provides a traction machine for the production of automotive seals.

[0004] The technical solution provided in this application for a traction machine used in the production of automotive sealing components is as follows: A traction machine for producing automotive sealing components includes a frame and a conveying device mounted on the frame. The conveying device includes an upper conveying assembly and a lower conveying assembly. The lower conveying assembly is fixedly mounted on the frame, and the upper conveying assembly is driven to move up and down by a lifting mechanism. Both the upper and lower conveying assemblies include a conveyor belt and side plates located on both sides of the conveyor belt. A drive roller and a driven roller for driving the conveyor belt to rotate are installed between the side plates, and several sets of support rollers are installed between the drive roller and the driven roller. The support rollers are used to support the conveyor belt and ensure its smooth transmission. The drive roller drives the conveyor belt to drive through a servo motor. The conveyor belt of the upper conveying assembly and the conveyor belt of the lower conveying assembly are clamped and cooperated vertically to realize the traction and conveying of the sealing strip. The frame has an inlet and an outlet at both ends of the conveying path corresponding to the lower conveying assembly.

[0005] Furthermore, the lifting mechanism includes a hinge plate and a cylinder. The two ends of the hinge plate are rotatably connected to the side plate of the upper conveying assembly and the frame, respectively. A connecting plate is fixed to the top outer side of the side plate. The cylinder body is rotatably connected to the frame, and the piston rod is rotatably connected to the connecting plate. The upper conveying assembly is lifted and lowered by the extension and retraction of the cylinder. An L-shaped fixing plate is installed in the middle of the outer side of the side plate of the upper conveying assembly. A lifting cylinder is installed on the frame corresponding to the bottom of the L-shaped fixing plate. A universal conveying ball is fixedly installed at the output end of the lifting cylinder, and the universal conveying ball rolls in contact with the bottom surface of the L-shaped fixing plate.

[0006] Furthermore, both the inlet and outlet are equipped with a lateral limiting mechanism and a longitudinal limiting mechanism. The lateral limiting mechanism includes a horizontal slide bar and two sets of opposing adjusting rollers slidably mounted on the horizontal slide bar. The longitudinal limiting mechanism includes a vertical slide bar and adjusting rollers fitted on the vertical slide bar. The adjusting rollers are all locked and fixed to the horizontal or vertical slide bar by an adjustable handle. An anti-tilting roller is added above the longitudinal limiting mechanism at the outlet. The anti-tilting roller is rotatably mounted on the frame, and its axis is parallel to the traction direction.

[0007] Furthermore, at least two sets of rectangular connecting frames are fixed between the two side plates of the upper or lower conveying assembly. The connecting frames adopt a frame structure, and their two ends are detachably connected to the side plates by bolts. The inner contour of the side plates is adapted to the running path of the conveyor belt to limit the lateral deviation of the conveyor belt.

[0008] Furthermore, the front side of the frame is provided with an observation window for observing the clamping and traction status of the conveying device. The observation window is embedded in the lifting plate. The two ends of the lifting plate are provided with sliders. The frame is provided with a sliding groove along the height direction. The sliders slide in the sliding groove. The bottom of the frame is provided with a drive cylinder corresponding to the lower part of the lifting plate. The output end of the drive cylinder is fixedly connected to the lifting plate, driving the lifting plate to rise and fall along the sliding groove.

[0009] Furthermore, a control panel is installed on the front of the frame. The control panel includes a display panel for displaying equipment operating parameters and control buttons for inputting control commands. A PLC controller is installed inside the frame. The PLC controller is electrically connected to the control panel, servo motor, cylinder of the lifting mechanism, lifting cylinder, and drive cylinder to realize the automated control of the traction machine.

[0010] In summary, this application includes at least one of the following beneficial technical effects: 1. This application utilizes the upper and lower clamping cooperation of the upper and lower conveying components, combined with the precise transmission driven by the servo motor and the flat support of the conveyor belt by the support roller, to effectively ensure the stability of the sealing strip traction conveying. With the lifting mechanism composed of the hinge plate and the cylinder, and the auxiliary support structure composed of the lifting cylinder and the universal conveying ball, the clamping distance and force of the upper and lower conveying components can be flexibly adjusted to adapt to sealing strips with different cross-sectional sizes and hardness, avoiding surface damage caused by excessive clamping or slippage and offset caused by excessive clamping. 2. The horizontal and vertical limiting mechanisms that can be locked and fixed at the inlet and outlet by the adjustable handle in this application can accurately limit the conveying path of the sealing strip. The anti-warping roller added at the outlet further prevents the sealing strip from warping. The cooperation between the side plate and the rectangular connecting frame avoids the lateral deviation of the conveyor belt, which significantly improves the straightness and dimensional accuracy of the product. 3. The liftable observation window on the front of the frame in this application allows operators to observe the internal clamping and traction status in real time. The electrical connection between the PLC controller, control panel, and various power components enables automated control of the equipment, reduces manual intervention, and improves production efficiency and product consistency. The overall structural design is reasonable and effectively solves the problems of poor adaptability, insufficient conveying stability, and inconvenient operation of existing traction machines, providing a reliable guarantee for the high-quality continuous production of automotive seals.

[0013] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0014] This application discloses a traction machine for the production of automotive seals.

[0015] Reference Figures 1 to 5A traction machine for producing automotive sealing components includes a frame 1 and a conveying device 2 mounted on the frame 1. The conveying device 2 includes an upper conveying assembly 21 and a lower conveying assembly 22. The lower conveying assembly 22 is fixedly mounted on the frame 1. The upper conveying assembly 21 is driven to lift by a lifting mechanism 3. Both the upper conveying assembly 21 and the lower conveying assembly 22 include a conveyor belt 23 and side plates 24 located on both sides of the conveyor belt 23. A drive roller 25 and a driven roller 26 for driving the conveyor belt 23 are installed between the side plates 24. Several sets of support rollers 27 are installed between the drive roller 25 and the driven roller 26 to support the conveyor belt 23 and ensure its smooth transmission. The drive roller 25 is driven by a servo motor 28 to drive the conveyor belt 23. The conveyor belt 23 of the upper conveying assembly 21 and the conveyor belt 23 of the lower conveying assembly 22 are clamped and cooperated vertically to realize the traction and conveying of the sealing strip. The frame 1 has an inlet 11 and an outlet 12 at both ends of the conveying path corresponding to the lower conveying assembly 22. During operation, the lower conveying component 22 remains fixed, while the upper conveying component 21 is adjusted to a height suitable for the sealing strip via the lifting mechanism 3. After the servo motor 28 starts, it drives the active roller 25 to rotate. The active roller 25 drives the conveyor belt 23 and the driven roller 26 to rotate synchronously. The support roller 27 between the active roller 25 and the driven roller 26 provides stable support for the conveyor belt 23. The roller surfaces of the active roller 25, the driven roller 26, and the support roller 27 mesh with the conveyor belt 23 to ensure that the conveyor belt 23 always remains flat. The sealing strip blank enters from the feed port 11 of the frame 1, and after being clamped by the upper and lower conveyor belts 23 of the upper conveying component 21 and the lower conveying component 22, it is precisely pulled by the transmission of the conveyor belt 23 and finally sent out from the discharge port 12, providing a stable conveying guarantee for subsequent processes.

[0016] Reference Figures 1 to 5The lifting mechanism 3 includes a hinge plate 31 and a cylinder 32. Both ends of the hinge plate 31 are rotatably connected to the side plate 24 of the upper conveying assembly 21 and the frame 1, respectively. A connecting plate 241 is fixed to the top outer side of the side plate 24. The cylinder body of the cylinder 32 is rotatably connected to the frame 1, and the piston rod end is rotatably connected to the connecting plate 241. The upper conveying assembly 21 is lifted and lowered by the extension and retraction of the cylinder 32. An L-shaped fixing plate 242 is installed in the middle of the outer side of the side plate 24 of the upper conveying assembly 21. A lifting cylinder 13 is installed on the frame 1 corresponding to the bottom of the L-shaped fixing plate 242. A universal conveying ball 131 is fixedly installed at the output end of the lifting cylinder 13, and the universal conveying ball 131 rolls in contact with the bottom surface of the L-shaped fixing plate 242. When it is necessary to adjust the clamping distance between the upper conveying component 21 and the lower conveying component 22, the cylinder 32 of the lifting mechanism 3 extends and retracts after receiving the control command. Its piston rod pushes or pulls the connecting plate 241 on the side plate 24 of the upper conveying component 21. Combined with the rotational connection between the hinge plate 31 and the frame 1 and the side plate 24, the upper conveying component 21 is driven to rotate and rise around the hinge point. At the same time, the lifting cylinder 13 operates synchronously. The universal conveying ball 131 at its output end supports the L-shaped fixing plate 242 of the side plate 24 of the upper conveying component 21. Without affecting the lifting action of the upper conveying component 21, the universal conveying ball 131 provides stable support for the upper conveying component 21 through rolling contact, ensuring the positional accuracy of the upper and lower conveying components 22 during the clamping process.

[0017] Reference Figures 1 to 5 Both the feed inlet 11 and the discharge outlet 12 are equipped with a lateral limiting mechanism 4 and a longitudinal limiting mechanism 5. The lateral limiting mechanism 4 includes a horizontal slide bar 41 and two sets of opposing adjusting rollers 42 slidably mounted on the horizontal slide bar 41. The longitudinal limiting mechanism 5 includes a vertical slide bar 51 and adjusting rollers 42 fitted on the vertical slide bar 51. The adjusting rollers 42 are locked and fixed to the horizontal slide bar 41 or the vertical slide bar 51 by an adjustable handle 43. An anti-tilting roller 121 is added above the longitudinal limiting mechanism 5 at the discharge outlet 12. The anti-tilting roller 121 is rotatably mounted on the frame 1, and its axis is parallel to the traction direction. According to the cross-sectional dimensions and specifications of the sealing strip, the operator loosens the adjustable handle 43 and slides the two sets of adjusting rollers 42 of the transverse limiting mechanism 4 along the horizontal slide bar 41 to match the width of the sealing strip. The operator then adjusts the height of the adjusting rollers 42 of the longitudinal limiting mechanism 5 along the vertical slide bar 51 to match the thickness of the sealing strip. After adjustment, the operator tightens the adjustable handle 43 to lock and fix the sealing strip. When the sealing strip enters from the feed inlet 11, its posture is corrected by the limiting of the transverse and longitudinal adjusting rollers 42 to avoid conveying deviation. When discharging, in addition to the transverse and longitudinal limiting mechanisms 5 continuing to play their role, the upper anti-warping roller 121 contacts the upper surface of the sealing strip and prevents the sealing strip from warping through rotation, ensuring the straightness of the conveying process.

[0018] Reference Figures 1 to 5At least two sets of rectangular connecting frames 243 are fixed between the two side plates 24 of the upper conveyor assembly 21 or the lower conveyor assembly 22. The connecting frames 243 adopt a frame structure, and their two ends are detachably connected to the side plates 24 by bolts. The inner contour of the side plates 24 is adapted to the running path of the conveyor belt 23 to limit the lateral deviation of the conveyor belt 23. Before the upper conveyor assembly 21 or the lower conveyor assembly 22 is put into operation, the rectangular connecting frames 243 are fixed between the two side plates 24 by bolts to enhance the structural stability of the side plates 24. When the conveyor belt 23 is running, the inner contour of the two side plates 24 is precisely adapted to the running path of the conveyor belt 23, forming a physical block against the lateral movement of the conveyor belt 23. At the same time, the rectangular connecting frames 243 further restrict the deformation of the side plates 24, ensuring the limiting effect of the side plates 24 on the conveyor belt 23, and effectively preventing the conveyor belt 23 from shifting laterally when it is under high-speed transmission or clamping force.

[0019] Reference Figures 1 to 5 The front side of the frame 1 is provided with an observation window 14 for observing the clamping and traction state of the conveying device 2. The observation window 14 is embedded in the lifting plate 15. The two ends of the lifting plate 15 are provided with sliders 151. The frame 1 is provided with a slide groove 16 along the height direction. The sliders 151 and the slide groove 16 are slidably engaged. The bottom of the frame 1 is provided with a drive cylinder 17 below the lifting plate 15. The output end of the drive cylinder 17 is fixedly connected to the lifting plate 15, driving the lifting plate 15 to rise and fall along the slide groove 16. During the operation of the traction machine, if the operator needs to observe the internal clamping and traction status, he can start the drive cylinder 17 through the control command. The output end of the drive cylinder 17 pushes the lifting plate 15. The lifting plate 15 slides up and down along the slide groove 16 of the frame 1 through the sliders 151 at both ends, which drives the observation window 14 embedded in the lifting plate 15 to adjust to a suitable height. The operator can clearly see the clamping status of the sealing strip, the running status of the conveyor belt 23, etc. through the observation window 14. After the observation is completed, the operator can control the drive cylinder 17 to drive the lifting plate 15 to reset, so that the observation window 14 returns to the initial position.

[0020] Reference Figures 1 to 5The front of the frame 1 is equipped with a control panel 18, which includes a display panel for displaying equipment operating parameters and control buttons for inputting control commands. A PLC controller 19 is installed inside the frame 1. The PLC controller 19 is electrically connected to the control panel 18, servo motor 28, and cylinders 32, 13, and 17 of the lifting mechanism 3, respectively, to achieve automated control of the traction machine. Before operation, the operator inputs parameters such as traction speed and clamping distance through the control buttons on the control panel 18 on the front of the frame 1. After receiving the commands, the PLC controller 19 sends control signals to components such as the servo motor 28, cylinders 32, 13, and 17 of the lifting mechanism 3. During operation, the PLC controller 19 receives real-time operating feedback data from each component and displays the equipment operating parameters through the display panel. If parameter adjustments are needed, the operator can input new commands through the control buttons, and the PLC controller 19 will immediately coordinate the responses of each component, achieving automated and coordinated operation of the traction machine's clamping, conveying, and observation actions.

[0021] Working principle: When this automotive sealing component production traction machine is working, the operator first inputs parameters such as the sealing strip size and traction speed through the control panel 18 on the front of the frame 1. After receiving the command, the PLC controller 19 coordinates the start of each component. First, the cylinder 32 of the lifting mechanism 3 drives the upper conveying assembly 21 to rotate and rise along the hinge plate 31. At the same time, the lifting cylinder 13 pushes the universal conveying ball 131 to support the L-shaped fixed plate 242, precisely adjusting the clamping distance and force of the upper and lower conveying assemblies 22 to adapt to the cross-sectional size and hardness of the sealing strip being processed. Then, according to the sealing strip specifications, the adjustable handles 43 of the horizontal limiting mechanism 4 and the vertical limiting mechanism 5 at the inlet 11 and outlet 12 are loosened. The adjusting roller 42 is slid along the horizontal slide bar 41 and the vertical slide bar 51 to the appropriate position and then locked. The anti-tilting roller 121 of the outlet 12 is simultaneously at the preset height. The system forms an all-around limiting channel; the servo motor 28 is started to drive the active roller 25 to rotate, which drives the conveyor belt 23 of the upper and lower conveyor components 22 to drive synchronously. The support roller 27 ensures that the conveyor belt 23 runs smoothly, while the side plate 24 and the rectangular connecting frame 243 prevent the conveyor belt 23 from shifting laterally. The sealing strip blank enters from the feed port 11, and after the posture is corrected by the limiting mechanism, it is smoothly clamped and precisely pulled by the upper and lower conveyor belts 23. During the process, the operator can control the lifting plate 15 to rise and fall along the slide 16 through the drive cylinder 17, and adjust the height of the observation window 14 to observe the internal clamping and traction status in real time. The PLC controller 19 receives the operating parameters in real time and displays them on the display panel. If adjustments are needed, instructions can be input through the control panel 18 to realize the automated and precise operation of the traction machine. Finally, the sealing strip is sent out through the discharge port 12 to adapt to subsequent cutting, vulcanization and other processes.

[0022] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
