Description

Technical Field

[0001] This invention relates to the technical field of sealant processing, and in particular to a mobile spraying device for the production of PP spare tire cover plates. Background Technology

[0002] As an important component of automotive interiors, PP spare tire covers not only need to possess certain structural strength, but their surface coatings also need to meet multiple requirements such as wear resistance, dirt resistance, and aesthetics. Therefore, the spraying process is one of the core steps in the production of PP spare tire covers. Currently, the demand for PP spare tire covers in the automotive interior parts manufacturing industry is increasing, while the requirements for production efficiency and coating quality are also constantly rising. At present, most of the PP spare tire cover spraying equipment widely used in the market is a single-station structure, which creates a bottleneck in the process that spraying and drying operations cannot be carried out in parallel. Statistics show that the production cycle of a single piece of traditional single-station equipment is as long as 8-10 minutes, with extremely low production efficiency, making it difficult to meet the needs of large-scale production of automotive parts. In addition, it can only process one workpiece at a time, and the equipment capacity gap is particularly obvious when facing large-volume orders.

[0003] To address the aforementioned issues, a mobile spraying device for the production of PP spare tire covers is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a mobile spraying device for the production of PP spare tire covers, so as to solve the problems of the existing mobile spraying devices for the production of PP spare tire covers mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mobile spraying device for producing PP spare tire cover plates, characterized in that it includes a bottom mounting base, an alternating moving component is arranged above the bottom mounting base, a drying component is arranged above one side of the alternating moving component, and a mobile spraying component is arranged above the other side of the alternating moving component. The alternating moving assembly includes a first mounting side plate and a second mounting side plate arranged in parallel and spaced apart, and a column support plate installed vertically on one side of the second mounting side plate. The inner sides of the first mounting side plate and the second mounting side plate are each equipped with a first guide rail, and the two sides of the column support plate are each equipped with a second guide rail. The first guide rail on the inner side of the first mounting side plate and the second guide rail on the outer side of the column support plate are respectively slidably connected to a first cover plate support platform. The first guide rail on the inner side of the second mounting side plate and the second guide rail on the inner side of the column support plate are respectively slidably connected to a second cover plate support platform. The height of the first cover plate support platform is higher than that of the second cover plate support platform, and the width of the second cover plate support platform is narrower than that of the first cover plate support platform. The drying component is fixedly installed on one side of the alternating moving component by pre-embedded bolts, and the working area of ​​the drying component corresponds to the moving path of the first cover plate support platform. The mobile spraying assembly is positioned directly above the alternating mobile assembly, and its spraying range completely covers the bearing areas of the first cover plate support and the second cover plate support.

[0006] Preferably, the alternating movement assembly further includes an end mounting platform, which is an L-shaped metal plate, and its vertical section is welded to the end between the first mounting side plate and the second mounting side plate.

[0007] Preferably, the horizontal section of the end mounting platform is rotatably mounted with a transmission wheel via a bearing seat. There are two transmission wheels, which are installed at both ends of the first mounting side plate and the second mounting side plate, and the central axes of the two transmission wheels remain parallel.

[0008] Preferably, a transmission belt is fitted on the outer side of the transmission wheel. The transmission belt is a synchronous belt, and its inner teeth mesh with the teeth of the transmission wheel for transmission.

[0009] Preferably, a first fixed seat is installed on the bottom side of the first cover plate support platform near the transmission belt. The first fixed seat is detachably fixed to the transmission belt by a set bolt, so that the movement of the transmission belt can drive the first cover plate support platform to slide synchronously.

[0010] Preferably, a second fixed seat is installed on the bottom side of the second cover plate support platform near the transmission belt. The second fixed seat has the same structure as the first fixed seat and is fixedly connected to the transmission belt by a set bolt. The fixed positions of the second fixed seat and the first fixed seat on the transmission belt are staggered, so that the two support platforms move in opposite directions when the transmission belt is running.

[0011] Preferably, a first movable slider is fixedly installed on the first guide rail on the side of the first mounting side plate corresponding to the first cover plate support platform by bolts, and a second movable slider is fixedly installed on the second guide rail on the right side of the first cover plate support platform corresponding to the column support plate by bolts. The inner sides of the first movable slider and the second movable slider are provided with sliding grooves that are adapted to the cross sections of the first guide rail and the second guide rail. The smooth movement of the first cover plate support platform is achieved by sliding cooperation with the first guide rail through the sliding grooves.

[0012] Preferably, a third movable slider is fixedly installed on the first guide rail on the side of the second mounting side plate corresponding to the second cover plate support platform by bolts, and a fourth movable slider is fixedly installed on the second guide rail on the left side of the second cover plate support platform corresponding to the column support plate by bolts. The inner sliding grooves of the third and fourth movable sliders are slidably engaged with the first and second guide rails respectively, and cooperate with the second fixed seat to realize the guiding movement of the second cover plate support platform.

[0013] Preferably, the drying assembly includes a mounting base and a drying fan. The mounting base is a door frame type frame, and its bottom is fixed to the bottom mounting base by expansion bolts. The top crossbeam is detachably fixed to the drying fan by clamps. There are two drying fans, and the air outlets are both set downwards, directly opposite the moving endpoint positions of the first cover plate support platform and the second cover plate support platform.

[0014] Preferably, the mobile spraying assembly includes a support column, an X-axis, a Y-axis, a Z-axis, and a spraying actuator. Two sets of support columns are arranged in a rectangular pattern and fixed to the base by anchor bolts. The top of the support column is fixedly connected to both ends of the X-axis by bolts. A support seat for the Y-axis is slidably fitted onto the outer side of the X-axis, and the extension direction of the Y-axis is perpendicular to the X-axis. A slider for the Z-axis is slidably fitted onto the outer side of the Y-axis, and the Z-axis extends vertically. Its bottom is fixedly connected to the spraying actuator via a flange, enabling the spraying actuator to move in three-dimensional space.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The core innovation of this device lies in the double-layered staggered support platform of the alternating moving components, combined with the synchronous belt reverse transmission design. The first and second cover plate support platforms adopt a double-layered staggered layout. Through the staggered fixation of the first and second fixed seats on the synchronous belt, the transmission belt drives the two support platforms to move in opposite directions when it is running. This ensures that when one support platform accurately enters the drying station of the drying component, the other support platform just reaches the spraying station of the moving spraying component. This design fundamentally breaks the bottleneck of the traditional equipment where spraying and drying cannot be carried out in parallel. It keeps the spraying and drying mechanisms in a working state at all times without idle time, improving efficiency by more than 60% compared with traditional single-station equipment and greatly increasing the production capacity of large-scale production.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0019] Example like Figure 1 As shown, this device is supported by a base 1 and has a rectangular frame structure. Its bottom is fixed to the concrete foundation of the ground by expansion bolts, and the top surface is milled to ensure flatness, providing a stable installation reference for the upper components. An alternating moving component 2 is fixedly installed on the top of the base 1 to realize the reverse alternating movement of the two workpiece bearing platforms. A drying component 3 is set on the upper left side of the alternating moving component 2. Its working area corresponds precisely to the movement path of the bearing platform and is used to quickly dry and cure the sprayed PP spare tire cover. A mobile spraying component 4 is installed across the upper right side of the alternating moving component 2. Its spraying range completely covers the bearing area of ​​the two bearing platforms, realizing all-round automated spraying of the workpiece.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the alternating moving component 2 is the core transmission component of this device, including a first mounting side plate 201 and a second mounting side plate 202 arranged in parallel and spaced apart. Both are vertically arranged rectangular steel plates and are detachably fixed to the top surface of the bottom mounting base 1 by pre-embedded bolts. On the right side of the second mounting side plate 202 (the side close to the second mounting side plate 201), column support plates 203 are installed at intervals in the vertical direction.

[0021] To achieve smooth sliding of the two support platforms, the inner sides (opposite surfaces) of the first mounting side plate 201 and the second mounting side plate 202 are fixedly installed with first guide rails 204 by hexagon socket bolts. The two first guide rails 204 are located at the same vertical height. On both sides of the column support plate 203, second guide rails 205 are installed parallel to the first guide rails 204. The first cover plate support platform 206 is a rectangular metal platform. Its right side (the side closest to the column support plate 203) is fixed to the second movable slider 214 by bolts, and its left side is fixed to the first movable slider 213 by bolts. The first movable slider 213 slides with the first guide rail 204 on the inner side of the first mounting side plate 201, and the second movable slider 214 slides with the second guide rail 205 on the right side of the column support plate 203, so as to achieve horizontal movement. The second cover plate support platform 207 is fixed to the third movable slider 215 by bolts on its left side, and to the fourth movable slider 216 by bolts on its right side. The third movable slider 215 slides with the first guide rail 204 on the inner side of the second mounting side plate 202, and the fourth movable slider 216 slides with the second guide rail 205 on the left side of the column support plate 203, forming a double-layer moving structure that intersects with the first cover plate support platform 206. The transmission components include an end mounting platform 208, a transmission wheel 209, and a transmission belt 210. The end mounting platform 208 is an L-shaped stainless steel plate. Its vertical section is fixed by welding to the end between the first mounting side plate 201 and the second mounting side plate 202. The horizontal section is arranged upwards. A transmission wheel 209 is rotatably mounted on the horizontal section through a bearing seat. The central axes of the two transmission wheels 209 at both ends are kept parallel, and the distance between them is consistent with the distance between the two mounting side plates. A transmission belt 210, which is a synchronous belt, is sleeved on the outside of the transmission wheel 209. The inner teeth of the transmission belt 210 mesh with the teeth of the transmission wheel 209 to ensure the accuracy of transmission. A first fixed seat 211 is installed on the bottom side of the first cover plate bearing platform 206 near the transmission belt 210, and a second fixed seat 212 is installed on the bottom side of the second cover plate bearing platform 207 near the transmission belt 210. Both are fixed to different sides of the synchronous belt by set bolts, and the fixing positions are staggered so that when the transmission belt 210 is running, it drives the two bearing platforms to move in opposite directions. The first cover plate support platform 206 is higher than the second cover plate support platform 207, and the second cover plate support platform 207 is narrower than the first cover plate support platform 207, so that the two support platforms do not affect each other during movement.

[0022] like Figure 5 As shown, the drying assembly 3 includes a mounting base 301 and a drying fan 302. The mounting base 301 is a rectangular frame, and its bottom is fixed to the top left side of the bottom mounting base 1 by expansion bolts. The internal width of the frame is adapted to the width of the alternating moving assembly 2 to ensure that the support platform can smoothly enter the drying area. On the top crossbeam of the mounting base 301, two drying fans 302 are symmetrically fixed by clamps. The drying fans 302 are electric heating hot air fans with a rated power of 3kW. The air outlets are all set downward so that the hot air can cover the moving end point of the first cover plate support platform 206 and the second cover plate support platform 207.

[0023] like Figure 4 As shown, the mobile spraying assembly 4 includes a support column 401, an X-axis 402, a Y-axis 403, a Z-axis 404, and a spraying actuator 405. Two sets of support columns 401 are symmetrically distributed on both sides of the alternating moving assembly 2. Each set of columns is fixed to the base 1 with anchor bolts. The top is precision-machined and then fixedly connected to both ends of the X-axis 402 with bolts. The X-axis 402 is a linear module driven by a ball screw, and a support seat for the Y-axis 403 is slidably fitted on its outer side. Similarly, the Y-axis 403... It is a linear module, extending perpendicular to the X-axis 402. A slider of the Z-axis 404 is slidably fitted on its outer side. The Z-axis 404 is a vertically arranged linear module used to adjust the height of the spraying actuator 405. The Z-axis 404 is fixedly connected to the spraying actuator 405 through a flange. The spraying actuator 405 uses a high-pressure airless spray gun, which can adjust the spraying pressure according to the coating requirements of the PP spare tire cover. With the linkage control of the X, Y and Z axes, it can achieve all-round spraying without dead angles on the surface of the workpiece.

[0024] Working principle of this invention: Refer to the instruction manual appendix Figure 1-5 Before the device is started, the first cover plate support platform 206 is located at the spraying station, and the second cover plate support platform 207 is located at the drying station and ready to be started. The operator places the PP spare tire cover plate to be sprayed on the top surface of the first cover plate support platform 206. The positioning boss on the top surface of the support platform accurately positions the workpiece. After the device is started, the X-axis 402, Y-axis 403 and Z-axis 404 of the moving spraying component 4 operate in conjunction with the three-dimensional model parameters of the workpiece, driving the spraying actuator 405 to move along the preset path. At the same time, the spraying actuator 405 is turned on, and the paint is evenly sprayed on the upper surface of the workpiece. During the spraying process, the drying component 3 is in standby mode, and the second cover plate support platform 207 remains stationary.

[0025] After the workpiece on the first cover plate support platform 206 completes single-sided spraying, the control system issues an alternating movement command. The transmission wheel 209 rotates clockwise under the drive of the drive motor, driving the first fixed seat 211 and the second fixed seat 212 to move in opposite directions through the transmission belt 210. The first cover plate support platform 206 moves from the spraying station to the drying station along the first guide rail 204 and the second guide rail 205. At the same time, the second cover plate support platform 207 moves from the standby position to the spraying station. When it moves to the preset position, the transmission mechanism stops running. At this time, the first cover plate support platform 206 is located directly below the two drying fans 302 of the drying component 3. The drying fans 302 start and blow hot air onto the surface of the workpiece to accelerate the curing of the coating. At the same time, the operator places the new workpiece to be sprayed on the second cover plate support platform 207 located at the spraying station. The mobile spraying component 4 immediately starts the single-sided spraying operation on the new workpiece, realizing the simultaneous spraying and drying.

[0026] When the new workpiece on the second cover plate support 207 has completed single-sided spraying and the workpiece on the first cover plate support 206 has completed drying, the control system issues an alternating movement command again. The transmission wheel 209 rotates counterclockwise, driving the two support plates to move in opposite directions. The second cover plate support 207 moves to the drying station for drying, and the first cover plate support 206 returns from the drying station to the spraying station. At this time, the operator flips the workpiece on the first cover plate support 206 that has been dried on one side so that the unsprayed side is facing up. The moving spraying component 4 then sprays the other side of the workpiece. At the same time, the workpiece on the second cover plate support 207 completes drying at the drying station.

[0027] After the workpiece on the first cover plate support 206 has completed double-sided spraying and the workpiece on the second cover plate support 207 has completed single-sided drying, the transmission mechanism is restarted, driving the first cover plate support 206 to move to the drying station to dry the second coating. The second cover plate support 207 returns to the spraying station, and the operator flips the workpiece on the second cover plate support 207 that has been dried on one side and starts spraying. After the workpiece on the first cover plate support 206 has completed double-sided drying, it is removed as a finished product, and a new workpiece to be sprayed is placed. The device then repeats the above process of feeding-spraying-alternating-drying-flipping-spraying-drying-removing to achieve continuous production.
