Description

Technical Field

[0001] This invention relates to the field of surface treatment equipment, and more particularly to a surface treatment apparatus for the production of curtain tracks. Background Technology

[0002] Currently, surface treatment equipment in the production of curtain tracks suffers from numerous technical limitations: traditional devices often separate grinding and debris removal into independent processes, requiring manual transfer of workpieces or replacement of modules, resulting in low production efficiency and the potential for residual debris to cause secondary scratches; in actual use, fixed brush bristles tend to accumulate metal debris after prolonged use, not only reducing cleaning effectiveness but also potentially scratching the already ground surface; furthermore, when grinding grooves for tracks of different specifications, existing equipment requires frequent changes of compatible grinding tools, making the adjustment process cumbersome, and the rigid grinding parts do not fit the curved surface of the groove well enough, often resulting in uneven grinding and excessive wear at the edges and corners, especially with poor compatibility with tracks made of different materials such as aluminum alloy and PVC, making it difficult to balance grinding precision and surface quality; in addition, existing equipment lacks a flexible control mechanism for grinding intensity, which can easily lead to fluctuations in product qualification rate due to fixed parameters, making it difficult to meet the high-efficiency and precise requirements of industrialized mass production. Therefore, we propose a surface treatment device for curtain track production to solve the aforementioned problems. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of the prior art by providing a surface treatment device for the production of curtain tracks.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a surface treatment device for curtain track production, comprising a frame, a control panel mounted on one side of the top of the frame, a vertical frame mounted on one side of the top of the frame, multiple horizontal frames mounted on the upper and lower parts of the vertical frame, threaded screws mounted on the bottom horizontal frames, stepper motors mounted at the top of the moving parts of the threaded screws, threaded rods mounted on the top driving ends of the middle stepper motors, and rotating shafts mounted on the top driving ends of the stepper motors on both sides. Grinding wheels are fixedly connected to the outer periphery of each rotating shaft, and evenly distributed fixing blocks are installed at intervals on the outer periphery of each grinding wheel. Each fixing block has an opening on one side. The device includes guide grooves, each with a guide bar slidably connected inside. A lifting frame is fixedly connected to the side of each guide bar away from the fixed block. A limit groove is formed on the top side of each lifting frame. A slider is rotatably connected to the top of the rotating shaft and the threaded rod. The sliders are slidably connected to the middle of the upper crossbar. A connecting frame is fixedly connected to the bottom of each slider. A fixed plate is fixedly connected to the bottom of each connecting frame. The fixed plates are all located on the upper part of the grinding wheel and are rotatably connected to the rotating shaft. A connecting piece is fixedly connected to the outer periphery of each fixed plate. A corrugated pipe is fixedly connected to the outer periphery of each connecting piece. The corrugated pipe is slidably connected inside the limit groove.

[0005] Preferably, the side of the lifting frame away from the fixed block is equipped with evenly distributed bristles, and the side of the lifting frame away from the fixed block is provided with a fixing plate.

[0006] Preferably, the lifting frame passes through the fixed plate and is slidably connected to the fixed plate, and connecting strips are fixedly connected to both sides of the fixed plate near the fixed block.

[0007] Preferably, the ends of the connecting strips away from the fixed plate are all fixedly connected to the fixed block, and the middle of the lifting frame has sliding grooves on both sides, with the connecting strips passing through the sliding grooves and slidably connected to the sliding grooves.

[0008] Preferably, roller frames are provided on both sides of the upright frame, and the roller frames are installed on both sides of the top of the machine frame. A curtain guide rail is provided on the top of the roller frame, and a fixing sleeve is provided on both sides of the roller frame.

[0009] Preferably, the fixed sleeves are all fixedly connected to the top of the frame, and the inner side of each fixed sleeve is rotatably connected to a rotating frame. Each rotating frame has a corner cylinder installed at its bottom, and the corner cylinder is installed inside the frame.

[0010] Preferably, each of the rotating frames is equipped with a motor, and each motor has a drive wheel fixedly connected to its bottom drive end. The drive wheels are located on both sides of the curtain track.

[0011] Preferably, the curtain rail has grooves on both sides, a fixing ring frame on both sides, a fixing bracket fixedly connected to the upper and lower parts of the fixing ring frame, a threaded connection between the middle of the fixing bracket and a threaded rod, and a polishing ring rotatably connected to the outer circumference of the fixing ring frame.

[0012] Preferably, the inner side of the grinding ring is provided with tooth grooves, and a gear is meshed with a portion of the inner side of each tooth groove. Each gear is set on one side of the fixed ring frame, and a servo motor is fixedly connected to the central shaft of each gear. Each servo motor is installed on one side of the fixed ring frame.

[0013] Preferably, an air pump is installed on the other side of the fixed ring frame, and the output of the air pump is connected to an expansion tube. The expansion tube is located on one side of the grinding ring, and lubricating oil and a lubricating coating are provided on the outer periphery of the expansion tube and the inner side of the grinding ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This invention integrates grinding and cleaning, improving work efficiency and cleanliness. By linking the bottom stepper motor with the threaded rod and rotating shaft, the grinding wheel is driven to rotate at high speed to achieve precise polishing. Innovatively, intermittently distributed lifting frames and bristles are set on the outer periphery of the grinding wheel, so that grinding and debris cleaning are completed simultaneously. More importantly, the lifting frame is in continuous contact with the corrugated tube on the outer periphery of the fixed plate through the limiting groove, and achieves continuous up and down reciprocating motion during rotation. Compared with the existing fixed cleaning structure, it significantly expands the cleaning coverage of the bristles, effectively solves the problems of debris residue and cleaning dead corners in traditional cleaning methods, greatly improves the continuity of operation and the cleanliness of the guide rail surface, and is more suitable for the needs of industrial mass production.

[0016] 2. This invention optimizes the brush cleaning mechanism to avoid secondary pollution and efficiency reduction. Addressing the problem in existing technologies where brush cleaning efficiency decreases due to debris adhesion, this invention utilizes a coordinated design of the fixing block and connecting strip. As the lifting frame moves up and down, the brush bristles and fixing plate form a continuous staggered motion, driving the bristles to oscillate at high frequency. This structure not only enhances the friction between the bristles and the guide rail surface, improving debris removal, but also completely removes adhered debris through centrifugal force. This solves the secondary pollution problem of traditional brushes that "get dirtier the more they sweep," easily scratching the polishing surface. It significantly extends the effective working time of the brush bristles and reduces equipment maintenance frequency.

[0017] 3. This invention achieves flexible and precise grinding by using adaptive multi-specification guide rails. When grinding the grooves of curtain guide rails of different specifications, traditional rigid grinding components often fail to fit the grooves properly, leading to uneven grinding. By employing a threaded rod to drive the lifting and lowering of the fixing frame and fixing ring, it can quickly adapt to guide rail grooves of different widths and depths. Furthermore, an air pump and expansion tube adjustment assembly are introduced. The air pump injects gas into the expansion tube, causing the expansion tube to drive the grinding ring to expand adaptively, achieving a perfect fit with the curved surface of the guide rail groove. Compared to rigid grinding components, this significantly improves the grinding uniformity of the inner side of the groove. By precisely adjusting the air pump's injection rate, the pressure of the grinding ring can be flexibly controlled, achieving flexible adjustment of the grinding intensity. This effectively avoids the problems of over-grinding or under-grinding caused by fixed intensity in existing technologies, adapting to the grinding needs of guide rails of different materials and significantly improving the finished product qualification rate.

[0028] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0029] like Figures 1-9The surface treatment device for producing curtain tracks shown includes a frame 101. A control panel 102 is installed on one side of the top of the frame 101. A vertical frame 111 is installed on one side of the top of the frame 101. Multiple horizontal frames 103 are installed on the upper and lower parts of the vertical frame 111. A threaded screw 114 is installed on each of the bottom horizontal frames 103. A stepper motor 132 is installed at the top of the moving part of each threaded screw 114. A threaded rod 131 is installed at the top drive end of each middle stepper motor 132. A rotating shaft 126 is installed at the top drive end of each side stepper motor 132. A grinding wheel 112 is fixedly connected to the outer periphery of each rotating shaft 126. Evenly distributed fixing blocks 120 are installed at intervals on the outer periphery of each grinding wheel 112. A guide groove 119 is opened on one side of each fixing block 120. The guide groove 119 has a sliding groove inside. A guide bar 128 is dynamically connected. A lifting frame 115 is fixedly connected to the side of the guide bar 128 away from the fixed block 120. A limit groove 130 is opened on the top side of the lifting frame 115. A slider 116 is rotatably connected to the top of the outer periphery of the rotating shaft 126 and the threaded rod 131. The slider 116 is slidably connected to the middle of the upper cross frame 103. A connecting frame 124 is fixedly connected to the bottom of the slider 116. A fixed plate 117 is fixedly connected to the bottom of the connecting frame 124. The fixed plate 117 is set on the upper part of the grinding wheel 112. The fixed plate 117 is rotatably connected to the rotating shaft 126. A connecting piece 125 is fixedly connected to the outer periphery of the fixed plate 117. A bellows 123 is fixedly connected to the outer periphery of the connecting piece 125. The bellows 123 is slidably connected to the inner side of the limit groove 130.

[0030] Furthermore, in specific implementation, the bottom threaded screw 114 can drive the polishing structures on both sides to approach the side wall of the curtain rail 110, thereby facilitating subsequent polishing work. The operation of each stepper motor 132 at the bottom can drive each threaded rod 131 and the rotating shaft 126 to rotate. The rotating shaft 126 can drive each polishing wheel 112 to rotate. The high-speed rotation of the polishing wheels 112 can achieve polishing of the contacting curtain rail 110. The intermittent rotation of the outer circumference of the polishing wheels 112... The distributed lifting frame 115 and brush bristles 118 can sweep and clean up the debris after the grinding and polishing process, which is beneficial to practical use. During the grinding process, the limiting groove 130 on the lifting frame 115 will continuously contact the corrugated pipe 123 on the outer periphery of the fixed plate 117. Under the guidance of the corrugated pipe 123, when the grinding wheel 112 and the lifting frame 115 rotate, the lifting frame 115 will be driven to move up and down continuously, which can further improve the working effect of the lifting frame 115 and is beneficial to practical use.

[0031] The lifting frame 115 has evenly distributed bristles 118 installed on the side away from the fixed block 120. The lifting frame 115 is also provided with a fixed plate 121 on the side away from the fixed block 120. The lifting frame 115 passes through the fixed plate 121 and is slidably connected to the fixed plate 121. Connecting strips 129 are fixedly connected to both sides of the fixed plate 121 near the fixed block 120. The ends of the connecting strips 129 away from the fixed plate 121 are fixedly connected to the fixed block 120. Slide grooves 127 pass through both sides of the middle of the lifting frame 115. The connecting strips 129 pass through the slide grooves 127 and are slidably connected to the slide grooves 127.

[0032] Furthermore, in specific implementation, during the up-and-down movement of the lifting frame 115, the fixing block 120 and the connecting strip 129 can fix the fixing plate 121, so that when the lifting frame 115 moves up and down, the bristles 118 will continuously misalign with the fixing plate 121, thereby enabling the bristles 118 on the lifting frame 115 to continuously swing, thereby further improving the cleaning effect of the bristles 118. At the same time, the continuous swinging of the bristles 118 can shake off the debris adhering to the bristles 118, which is conducive to improving the continuous working effect of the bristles 118.

[0033] The stand 111 has roller frames 105 on both sides, which are installed on the top of the frame 101. A curtain rail 110 is installed on the top of the roller frame 105. Fixed sleeves 107 are installed on both sides of the roller frame 105 and are fixedly connected to the top of the frame 101. A rotating frame 104 is rotatably connected to the inside of the fixed sleeve 107. A corner cylinder is installed at the bottom of the rotating frame 104 and is installed inside the frame 101. A motor is installed at the end of the rotating frame 104 and a drive wheel 106 is fixedly connected to the bottom drive end of the motor. The drive wheel 106 is located on both sides of the curtain rail 110.

[0034] Furthermore, in specific implementation, the equipment can be used to grind and polish the curtain rail 110. During operation, the roller frame 105 supports and guides the curtain rail 110. At the same time, the corner cylinders at the bottom of the fixed sleeves 107 on both sides can drive the rotating frame 104 and the drive wheel 106 to deflect. The drive wheels 106 on both sides can center and clamp and limit the curtain rail 110. The motor installed at the end of the rotating frame 104 can drive the drive wheel 106 to rotate. The drive wheel 106 can drive the curtain rail 110 in contact with it to move, so that the curtain rail 110 can move along the roller frame 105. This allows the roller frame 105 to pass stably through the grinding and polishing structure at the top of the frame 101, thus achieving the grinding work on the roller frame 105.

[0035] The curtain track 110 has grooves on both sides and a fixing ring 133 on both sides. The fixing ring 133 is fixedly connected to the upper and lower parts of the fixing frame 108. The middle part of the fixing frame 108 is threadedly connected to the threaded rod 131. The outer circumference of the fixing ring 133 is rotatably connected to the polishing ring 113. The inner side of the polishing ring 113 is provided with a toothed groove 122. A gear 135 is meshed with a part of the inner side of the toothed groove 122. The gear 135 is located inside the fixing ring 133. The middle shaft of the gear 135 is fixedly connected to a servo motor. The servo motor is installed inside the fixing ring 133. An air pump 134 is installed on the other side of the fixing ring 133. The output part of the air pump 134 is connected to an expansion tube 109. The expansion tube 109 is located inside the polishing ring 113. The outer circumference of the expansion tube 109 and the inner side of the polishing ring 113 are provided with lubricating oil and lubricating coating.

[0036] Furthermore, in specific implementation, the operation of the threaded rod 131 drives the fixing frame 108 and the fixing ring frame 133 to move up and down, so that the polishing ring 113 can correspond to the grooves on both sides of the curtain rail 110, enabling it to accommodate curtain rails 110 of different specifications. Furthermore, during operation, the operation of the servo motor drives the gear 135 to rotate, which in turn drives the polishing ring 113 to rotate rapidly. This high-speed rotation of the polishing ring 113 achieves the desired effect on the curtain rail. The polishing of the grooves on both sides of the curtain track 110 is beneficial for practical use. During this process, the air pump 134 will start working. The operation of the air pump 134 can pump gas into the expansion tube 109, thereby expanding the expansion tube 109. This allows the polishing ring 113 at the expansion tube 109 to fit more perfectly into the grooves on both sides of the curtain track 110, which helps to improve the polishing effect. At the same time, by adjusting the pumping amount of the air pump 134, the polishing intensity of the polishing ring 113 can be adjusted, making it more suitable for polishing the curtain track 110.

[0037] Working principle:

[0038] In practical use, the equipment allows for the grinding and polishing of the curtain track 110. During operation, the roller frame 105 supports and guides the curtain track 110. Simultaneously, the corner cylinders at the bottom of the fixed sleeves 107 on both sides drive the rotating frame 104 and the drive wheel 106 to deflect. The drive wheels 106 on both sides center and clamp the curtain track 110. The motor installed at the end of the rotating frame 104 drives the drive wheel 106 to rotate, which in turn moves the curtain track 110 in contact with it, allowing the curtain track 110 to move along the roller frame 105. This ensures that the roller frame 105 can stably pass over the grinding and polishing area at the top of the frame 101. The structure enables the grinding of the roller frame 105. The bottom threaded screw 114 drives the grinding and polishing structures on both sides to approach the side wall of the curtain rail 110, facilitating subsequent grinding. The operation of each stepper motor 132 at the bottom drives each threaded rod 131 and rotating shaft 126 to rotate. The rotating shaft 126 drives each grinding wheel 112 to rotate. The high-speed rotation of the grinding wheels 112 achieves grinding and polishing of the contacting curtain rail 110. The intermittently distributed lifting frames 115 and brush bristles 118 on the outer periphery of the grinding wheels 112 enable the sweeping and cleaning of grinding debris after the polishing process, which is beneficial for practical use. During the grinding process, the limiting groove 130 on the lifting frame 115 will engage with the fixed... The corrugated pipe 123 on the outer periphery of the disc 117 is in continuous contact. Guided by the corrugated pipe 123, the grinding wheel 112 and the lifting frame 115 rotate, causing the lifting frame 115 to move continuously up and down. This further improves the working effect of the lifting frame 115 and is beneficial for practical use. Furthermore, during the up-and-down movement of the lifting frame 115, the fixing block 120 and connecting strip 129 fix the fixing plate 121, causing the bristles 118 to continuously misalign with the fixing plate 121 as the lifting frame 115 moves up and down. This allows the bristles 118 on the lifting frame 115 to continuously oscillate, further improving the cleaning effect of the bristles 118. Simultaneously, the continuous oscillation of the bristles 118... This mechanism effectively removes debris adhering to the bristles 118, improving their continuous working efficiency. In actual use, the threaded rod 131 moves the fixing bracket 108 and the fixing ring bracket 133 up and down, allowing the polishing ring 113 to align with the grooves on both sides of the curtain track 110, accommodating different sizes of curtain tracks 110. Furthermore, during operation, the servo motor drives the gear 135 to rotate, which in turn drives the meshing polishing ring 113 to rotate rapidly. This high-speed rotation of the polishing ring 113 polishes the grooves on both sides of the curtain track 110, enhancing its practical use. During this process, the air pump 134 also starts operating.The air pump 134 pumps air into the expansion tube 109, inflating it and allowing the polishing ring 113 to fit more perfectly into the grooves on both sides of the curtain track 110. This improves the polishing effect. Furthermore, by adjusting the pumping rate of the air pump 134, the polishing intensity of the polishing ring 113 can be adjusted, making it more suitable for polishing the curtain track 110.
