Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment technology, and in particular to a sheet metal spraying and conveying device. Background Technology

[0002] In the field of sheet metal processing (such as metal sheets, wood sheets, and composite material sheets), surface coating is a key process for improving the weather resistance and aesthetics of products. Traditional coating production lines generally use the following two conveying methods: fixed conveyor lines horizontally transport sheets via chains or roller conveyors. Although continuous transport is possible, significant drawbacks exist: only one side of the sheet is exposed to the spray gun, requiring manual rotation for comprehensive coating, resulting in low efficiency. Furthermore, traditional conveying devices suffer from the following problems: inaccurate sheet positioning during transport leads to uneven coating; multi-angle continuous coating is impossible; the equipment occupies a large area with limited effective working space; and the complex mechanical structure results in high maintenance costs. Especially when processing large or irregularly shaped sheets, existing conveying devices struggle to maintain a stable transport trajectory, easily causing deviations or vibrations, severely impacting coating quality. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to provide a sheet metal spraying and conveying device that can improve spraying efficiency, achieve multi-angle continuous spraying, enhance conveying stability, and reduce maintenance costs.

[0004] This utility model is implemented using the following method: a sheet metal spraying and conveying device, comprising annular support frames at both ends, annular guide rails on the annular support frames, multiple support rods evenly spaced on the inner side of the annular guide rails, annular guide rods at the ends of the support rods, sliding members evenly spaced on the annular guide rods, a movable seat for placing the sheet metal on the sliding member, first guide wheels on all four sides of the lower surface of the movable seat, the first guide wheels being embedded in the annular guide rails, a first motor embedded in the middle of the upper surface of the movable seat, and a placement rotating plate for placing the sheet metal at the end of the output shaft of the first motor.

[0005] Furthermore, the sliding component includes a U-shaped sliding seat, on which the U-shaped sliding seat is sleeved. A rack is provided on the lower surface of the annular guide rod. A second motor is provided at the lower end of the right side of the U-shaped sliding seat. A U-shaped block is provided on the inner bottom surface of the U-shaped sliding seat. The end of the output shaft of the second motor is mounted in the U-shaped block via a bearing. A gear that meshes with the rack is provided on the output shaft of the second motor. A second guide wheel is provided on both the inner right side and the upper surface of the U-shaped sliding seat, and the second guide wheel is in contact with the annular guide rod. A support column is provided on the upper surface of the U-shaped sliding seat. A support sleeve is sleeved on the support column. The rear surface of the support sleeve is connected to the movable seat via a connecting block. The connecting block is connected to the movable seat via bolts.

[0006] Furthermore, limit blocks are provided inward at the lower ends of the two vertical plates of the U-shaped sliding seat.

[0007] The beneficial effects of this utility model are as follows: This utility model achieves multi-angle positioning of the plate by driving the sliding part through the ring guide rod, and ensures the conveying stability by combining the guide wheel and gear rack transmission structure. It effectively solves the problems of low single-sided spraying efficiency and poor positioning accuracy of traditional devices, and has the advantages of improving spraying efficiency, realizing multi-angle continuous spraying, enhancing conveying stability and reducing maintenance costs.

[0012] The present invention will be further described below with reference to the accompanying drawings.

[0013] Please see Figures 1 to 4As shown, this utility model provides an embodiment: a sheet metal spraying and conveying device, including annular support frames 1 at both ends, annular guide rails 2 on the annular support frames 1, multiple support rods 3 evenly spaced on the inner side of the annular guide rails 2, annular guide rods 4 at the ends of the support rods 3, sliding members 5 evenly spaced on the annular guide rods 4, and a movable seat 6 for placing the sheet metal on the sliding member 5. First guide wheels 61 are arranged around the lower surface of the movable seat 6, and the first guide wheels 61 are embedded in the annular guide rails 2. A first motor (not shown) is embedded in the middle of the upper surface of the movable seat 6, and a placement rotating plate 62 for placing the sheet metal is arranged at the end of the output shaft of the first motor.

[0014] The components are as follows: 1. Annular support frame: This refers to the main frame structure supporting the entire conveying device. It can be made of welded steel, and its annular structure provides a circulating running path for the moving parts. 2. Annular guide rail: This refers to the guide structure set on the support frame. It can be made of I-beam steel rails and is used to constrain the running trajectory of the moving seat. 3. Support rod: This refers to the rigid component connecting the annular guide rail and the guide rod. It can be made of rectangular steel tubing, and its equidistant distribution ensures uniform force distribution. 4. Annular guide rod: This refers to the annular component set at the end of the support rod. It can be made of hollow round tubes bent into shape and serves as the moving reference for the sliding parts. 5. Sliding part: This refers to the bearing mechanism that moves along the guide rod. It can be made of a sliding seat with rollers and is used to transmit power and support the moving seat. 6. Moving seat: This refers to the component that directly supports the plate material. It can be made of welded steel plate box structure, and its bottom guide wheel ensures smooth movement along the track. 61. First guide wheel: This refers to the rolling component installed at the bottom of the moving seat. It can be made of nylon-coated rollers and works with the track to achieve low-friction movement. The first motor refers to the power device that drives the rotation of the placement plate, which can be implemented using a servo motor. Precise control allows for adjustment of the plate's angle. The placement and rotating plate is the working platform for fixing the plate, which can be made of aluminum alloy flat plate with positioning clamps on its surface to ensure the plate's stability.

[0015] Specifically, the moving seat circulates along a circular guide rail via bottom guide wheels. When the moving seat enters the spraying area, the first motor drives the rotating plate to rotate axially. This rotation automatically changes the spraying surface of the sheet material during transport, allowing operators to complete double-sided spraying without interrupting the production line. The spatial frame structure composed of the support rod and the circular guide rod provides stable support for the sliding components and ensures that multiple moving seats maintain equidistant movement. The embedded design of the guide wheels and the rail effectively prevents the moving seat from shifting during high-speed operation, ensuring the positioning accuracy of the spraying operation.

[0016] Compared to existing technologies, traditional fixed conveyor lines require manual intervention in the orientation of the sheet metal. This solution, however, achieves fully automated spraying by integrating a rotating mechanism and a circulating conveyor system. Existing technologies can only process one side of the sheet metal at a time, while this solution allows for full-surface spraying during continuous conveying, significantly improving production line efficiency. Furthermore, the composite structure of the circular guide rail and guide rod effectively increases the number of workstations per unit area compared to traditional linear tracks.

[0017] Through the above technical solution, this application achieves automatic rotation of the sheet material during the conveying process, enabling continuous multi-sided spraying of the sheet material and eliminating the efficiency loss caused by manual rotation. The coordinated design of the moving seat and guide wheels ensures the stability of the sheet material conveying and avoids uneven spraying caused by vibration. The circular guide rail layout optimizes the space utilization of the equipment, allowing more spraying stations to be arranged within the same area.

[0018] Please continue reading. Figures 1 to 4 As shown in one embodiment of the present invention, the sliding member 5 includes a U-shaped sliding seat 51. The U-shaped sliding seat 51 is sleeved on the annular guide rod 4. A rack (not shown) is provided on the lower surface of the annular guide rod 4. A second motor 52 is provided at the lower end of the right side of the U-shaped sliding seat 51. A U-shaped block 53 is provided on the inner bottom surface of the U-shaped sliding seat 51. The end of the output shaft of the second motor 52 is provided in the U-shaped block 53 via a bearing. A gear 54 that meshes with the rack is provided on the output shaft of the second motor 52. A second guide wheel 55 is provided on both the inner right side and the upper surface of the U-shaped sliding seat 51. The second guide wheel 55 is in contact with the annular guide rod 4. A support column 56 is provided on the upper surface of the U-shaped sliding seat 51. A support sleeve 57 is sleeved on the support column 56. The rear surface of the support sleeve 57 is connected to the movable seat 6 via a connecting block 58. The connecting block 58 is connected to the movable seat 6 via bolts.

[0019] Among them, the U-shaped sliding seat 51 refers to a metal component with a U-shaped cross-section and an opening facing left, which can be made by bending steel plate, and is used to wrap the annular guide rod and form a sliding track. The rack refers to a strip-shaped gear structure continuously arranged along the lower surface of the annular guide rod, which can be made by milling 45# steel, and is used to mesh with the gear to form a transmission pair. The second guide wheel refers to a nylon roller with a bearing, which can be made by polyurethane-coated wheel, and is used to constrain the movement trajectory of the U-shaped sliding seat on the annular guide rod. The support sleeve refers to a metal tube with internal threads, which can be made by turning aluminum alloy tube, and is used to adjust the height position of the moving seat through the threads.

[0020] Specifically, when the second motor drives the gear to rotate, the meshing action of the gear and rack pushes the U-shaped sliding seat to move along the annular guide rod. The second guide wheel rolls on the upper and lower surfaces of the annular guide rod, forming a double limit. The vertical distance between the moving seat and the U-shaped sliding seat can be adjusted by rotating the support sleeve via a thread. The connecting block achieves a detachable connection between the moving seat and the support sleeve through bolts. This structure ensures the accuracy of the moving seat's movement on the annular track through gear and rack transmission, while also allowing the height of the moving seat to be adjusted according to the thickness of the sheet metal.

[0021] Compared with existing technologies, traditional fixed conveyor lines require manual flipping of the plates for double-sided spraying. This solution, however, uses a movable U-shaped sliding seat and a height-adjustable moving seat to automatically complete the positioning and posture adjustment of the plates during the conveying process, enabling multi-angle spraying operations without interrupting the production line.

[0022] Through the above technical solution, this application achieves precise positioning and height adjustment of the sheet material during the conveying process, solving the problem that traditional equipment needs to stop to adjust the position of the sheet material, enabling sheet materials of different thicknesses to continuously enter the spraying area, and significantly improving the automation level of the production line.

[0023] Please continue reading. Figure 4 As shown, in one embodiment of the present invention, a limiting block 50 is provided inward at the lower end of the two vertical plates of the U-shaped sliding seat 51.

[0024] Among them, the U-shaped sliding seat 51 refers to a U-shaped metal component consisting of a bottom horizontal plate and two side vertical plates. Specifically, it can be made of welded steel plate and is used to support the gear transmission mechanism.

[0025] The lower surface end of the vertical plate refers to the bottom edge area of ​​the vertical plates on both sides of the U-shaped component. Specifically, it can be milled to form a flat end face for installing the limiting structure.

[0026] Among them, the limiting block 50 refers to the blocking component protruding from the inner side of the vertical plate. Specifically, it can be implemented by a rectangular steel block fixed with bolts. Its function is to limit the axial displacement range of the sliding seat on the annular guide rod.

[0027] Specifically, as the sliding seat moves along the annular guide rod, the limiting block physically interferes with both sides of the guide rod. When the sliding seat reaches the turning section of the track, the limiting block contacts the side wall of the guide rod, generating a restraining force that prevents the sliding seat from shifting laterally due to centrifugal force. This structure maintains the relative positional relationship between the sliding component and the guide rod through mechanical limiting, preventing the sliding seat from detaching from the track and causing an interruption in the spraying process.

[0028] Compared to existing technologies, traditional sliding components rely on the friction between the guide wheel and the track to maintain their position during turns, which carries the risk of derailment due to accumulated sliding component offset. This solution actively constrains the displacement of the sliding component through a rigid limiting structure, maintaining stable guidance even under sharp turns or high-speed operation, significantly reducing the frequency of equipment downtime for maintenance.

[0029] Through the above technical solution, this application effectively prevents the sliding parts from shifting laterally in the turning section of the circular track, avoids the problem of spraying interruption caused by the sliding parts derailing, and ensures continuous and stable operation of the sheet material conveying process.

[0030] The above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall be covered by the present utility model.
