Description

Technical Field

[0001] This utility model relates to the field of spray equipment technology, and in particular to a vertical rotating spray equipment with a toothed chain drive and a limit release mechanism. Background Technology

[0002] In the field of vertical rotary spray equipment, existing technologies typically use an independent power source to drive the rotation of the fixture to ensure that the product is evenly sprayed during the spraying process. This design relies on an additional rotary drive mechanism, which enables the fixture to rotate during the conveying process, thereby improving the spraying effect and coverage.

[0003] However, the existing technology has the drawback of controlling the start and stop of the rotation power source of the conveying device and the fixture separately. In actual operation, the product passes through the production line while being sprayed and does not stop in one place to wait for a long time to be sprayed. Therefore, this separate control not only increases the complexity of the system, but is also unnecessary in practical applications, resulting in cumbersome equipment structure and low control efficiency.

[0004] Therefore, the inventors urgently need a vertical rotating spray device with a toothed chain drive and a limit release mechanism to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned defects in the prior art, this utility model provides a vertical rotating spraying device with a toothed chain drive and a limit release mechanism, which aims to solve the problems of complex equipment structure and low control efficiency caused by the separate control of the conveying device and the rotation power source of the fixture in the existing vertical rotating spraying device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a vertical rotating spraying device with a toothed chain drive and a limit release mechanism, comprising a drive line, a spraying line disposed on one side of the drive line, and a rotating drive line disposed between the drive line and the spraying line. The drive line includes a conveying device and a plurality of vertical rotating devices disposed on the conveying device. The vertical rotating device includes a mounting frame, anti-rotation components respectively hinged to both sides of the mounting frame, and a gear jig assembly rotatably fitted to the outer end of the mounting frame. The rotating drive line includes a continuous rack structure and an anti-rotation control structure. The access end of the anti-rotation control structure is closer to the input end of the conveying device than the access end of the continuous rack structure. The anti-rotation component includes a hinge plate, an anti-rotation control handle disposed at the lower end of the hinge plate, and a return spring disposed at the upper end of the hinge plate. The other end of the return spring is connected to the mounting frame.

[0007] Based on the above, the beneficial effect of a vertical rotating spraying device with a toothed chain drive and limit release mechanism is to solve the problems of complex equipment structure and low control efficiency caused by the separate control of the conveying device and the rotation power source of the fixture in the existing vertical rotating spraying device; mainly reflected in: 1. In this utility model, the access end of the anti-rotation control structure is closer to the input end of the conveying device than the access end of the continuous rack structure. This allows the anti-rotation control structure to act on the vertical rotation device before the continuous rack structure. The anti-rotation control structure acts on the anti-rotation control handle of the anti-rotation assembly, forcing the hinge plate to rotate against the tension of the return spring. This releases the rotation restriction of the anti-rotation end on the gear fixture assembly, realizing the automatic and reliable release of the rotation limit before the fixture enters the spray area, thus preparing for the subsequent continuous rotation drive. 2. This utility model, after the limit of the drive gear is released by the anti-rotation control structure, allows the continuous rack structure to mesh with the drive gear in the released gear fixture assembly. Due to the continuous movement of the conveying device, the drive gear passively rolls on the continuous rack, thereby driving the entire fixture mounting column and the product on it to rotate at a constant speed within the spray line. This achieves simultaneous driving of fixture translation and rotation using only a single power source of the conveying device, simplifying the power system. 3. This utility model, through the cooperation of the hinge plate and the mounting frame with the return spring, after the vertical rotation device moves out of the spray area and disengages from the anti-rotation control structure, the return spring, under its restoring force, drives the hinge plate and the anti-rotation end to reset, so that the anti-rotation end is re-engaged into the rotation limit port of the drive gear. This realizes automatic locking of the fixture's rotation in the non-spray area, preventing unnecessary shaking or rotation during the conveying process and ensuring operational stability.

[0008] Furthermore, the rotation-stopping assembly also includes a rotation-stopping end, which is located in the middle of the connecting piece between the two symmetrically arranged hinge pieces. The gear fixture assembly includes a drive gear, a fixing ring coaxially arranged on the outer end face of the drive gear, and a fixture mounting post installed in the fixing ring. The drive gear is provided with a rotation limiting port. When the vertical rotation device is located in the starting area of ​​the drive line, the rotation-stopping end is adapted to the rotation limiting port.

[0009] Based on the above, the beneficial effects of the anti-rotation end are: providing reliable single-point limiting, enabling the gear fixture assembly to be firmly locked in the initial angular position in the starting area of ​​the drive line; the beneficial effect of the hinge plate is: realizing a symmetrical linkage control method, allowing synchronous rotation when the anti-rotation control handle is subjected to external force, ensuring that the anti-rotation end smoothly disengages from the rotation limit port; the beneficial effect of the drive gear is: simultaneously undertaking the dual functions of transmission and limiting, both meshing with the continuous rack structure to transmit rotational power and cooperating with the anti-rotation end through its rotation limit port to achieve angular positioning, realizing that a single component simultaneously meets the requirements of rotational drive and precise positioning; the beneficial effect of the fixed ring is: providing a stable installation benchmark, ensuring that the rotation center of the fixture mounting column is completely consistent with the rotation center of the drive gear; the beneficial effect of the fixture mounting column is: realizing the bearing and positioning of the product fixture, achieving stable fixation of the product during rotation; the beneficial effect of the rotation limit port is: providing a clear mechanical limit point on the drive gear.

[0010] Furthermore, the resistance control structure includes a release ramp located on the input side of the transmission device and a sustaining release plane extending from the release ramp to the output side of the transmission device.

[0011] Based on the above, the beneficial effects of the release slope are that it provides a smooth initial release guide, and through its inclined slope structure, it gradually acts on the anti-rotation control handle, realizing a smooth transition of the anti-rotation component from the locked state to the released state, avoiding rigid impact; the beneficial effect of maintaining the release plane is that it provides a continuous and stable release retention, and by maintaining continuous contact with the anti-rotation control handle, it realizes the reliable maintenance of the release state of the anti-rotation component throughout the entire spray area.

[0012] Furthermore, the rack region of the continuous rack structure corresponds to the extended region of the maintaining unrestricted plane.

[0013] Furthermore, the vertical rotation device also includes a drive base and a counterweight seat disposed on the drive base. The mounting frame is disposed on the counterweight seat near the spray line, and a counterweight block is installed on the other side of the counterweight seat.

[0014] Based on the above, the beneficial effects of the drive base are that it provides a stable and reliable installation foundation, and its sturdy base design supports the counterweight seat and mounting frame above, enabling the entire device to operate smoothly on the conveyor. The beneficial effect of the counterweight seat is that it achieves a reasonable layout and balance of the load. By arranging the mounting frame near the spray line and installing the counterweight on the other side, the center of gravity of the rotating device is optimized. The beneficial effect of the counterweight is that it provides precise balance, and the balancing torque generated by its mass counteracts the overturning torque generated by the fixture mounting column and its load, thus achieving dynamic stability during the operation of the device.

[0015] Furthermore, the fixture mounting post has a plurality of fixture mounting holes evenly arranged on it.

[0016] Based on the above, the beneficial effect of the fixture mounting holes is that they provide fixture mounting points. The regular distribution of the fixture mounting holes provides multiple mounting positions for the fixture, enabling multiple fixture products to perform spraying operations simultaneously.

[0017] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the following description, in conjunction with the accompanying drawings and specific embodiments, will further explain this utility model. Attached Figure Description

Detailed Implementation

[0020] like Figures 1-3As shown, a vertical rotating spray device with a toothed chain drive and a limit release mechanism includes a drive line 1, a spray line 2 disposed on one side of the drive line 1, and a rotating drive line 3 disposed between the drive line 1 and the spray line 2. The drive line 1 includes a conveying device 11 and a plurality of vertical rotating devices 12 disposed on the conveying device 11. Each vertical rotating device 12 includes a mounting frame 121, anti-rotation components 122 respectively hinged to both sides of the mounting frame 121, and teeth rotatably engaged with the outer end of the mounting frame 121. The wheel fixture assembly 123 includes a rotary drive line 3 comprising a continuous rack structure 31 and a rotation-stopping control structure 32. The access end of the rotation-stopping control structure 32 is closer to the input end of the conveying device 11 than the access end of the continuous rack structure 31. The rotation-stopping assembly 122 includes a hinge plate 1221, a rotation-stopping control handle 1222 disposed at the lower end of the hinge plate 1221, and a return spring 1223 disposed at the upper end of the hinge plate 1221. The other end of the return spring 1223 is connected to the mounting frame 121.

[0021] The anti-rotation assembly 122 further includes an anti-rotation end 1224, which is located in the middle of the connecting piece between two symmetrically arranged hinge pieces 1221. The gear fixture assembly 123 includes a drive gear 1231, a fixing ring 1232 coaxially arranged on the outer end face of the drive gear 1231, and a fixture mounting post 1233 installed in the fixing ring 1232. The drive gear 1231 is provided with a rotation limiting port 12311. When the vertical rotation device 12 is located in the starting area of ​​the drive line 1, the anti-rotation end 1224 is adapted to the rotation limiting port 12311.

[0022] The resistance control structure 32 includes a release slope 321 located on the input side of the transmission device 11 and a maintenance release plane 322 extending from the release slope 321 to the output side of the transmission device 11.

[0023] The rack region of the continuous rack structure 31 corresponds to the extended region of the maintaining release plane 322.

[0024] The vertical rotation device 12 also includes a drive base 124 and a counterweight seat 125 disposed on the drive base 124. The mounting frame 121 is disposed on the counterweight seat 125 near the spray line 2, and a counterweight block 1251 is installed on the other side of the counterweight seat 125.

[0025] The fixture mounting post 1233 has a plurality of fixture mounting holes 12331 evenly arranged on it.

[0026] In summary, the specific embodiments of this utility model are as follows: When the vertical rotation device 12 enters the starting area of ​​the drive line 1 through the conveying device 11, the anti-rotation end 1224 of the anti-rotation assembly 122 is locked into the rotation limit port 12311 of the drive gear 1231 under the action of the return spring 1223. At this time, the gear fixture assembly 123 is locked and cannot rotate. As the conveying device 11 continues to operate, the vertical rotating device 12 first approaches the rotating drive line 3. The release limit slope 321 of the anti-rotation control structure 32 contacts the anti-rotation control handle 1222 before the continuous rack structure 31, and pushes the anti-rotation control handle 1222 through its inclined slope, forcing the hinge piece 1221 to rotate against the tension of the return spring 1223, thereby driving the anti-rotation end 1224 to exit from the rotation limit port 12311, releasing the rotation restriction on the drive gear 1231. The vertical rotation device 12 continues to move forward, and the anti-rotation control handle 1222 enters the area of ​​the maintenance release plane 322. Under the continuous resistance of this plane, the anti-rotation component 122 remains in the release state at a certain angle with the mounting frame 121. At the same time, the released drive gear 1231 and the continuous rack structure 31 enter the meshing state. Due to the linear motion of the conveying device 11, the drive gear 1231 passively rolls on the fixed continuous rack structure 31, thereby driving the fixed ring 1232, the fixture mounting column 1233 and the products installed on it to rotate at a constant speed together next to the spray line 2 to complete the spraying operation. After the vertical rotation device 12 finishes spraying and moves out of the spraying area, the anti-rotation control handle 1222 gradually moves away from the range of action of the maintaining release plane 322. The restoring force of the reset spring 1223 pulls the hinge plate 1221 to rotate, causing the anti-rotation end 1224 to reset and re-engage in the rotation limit port 12311 of the drive gear 1231. The gear fixture assembly 123 is locked again until the next working cycle begins.

[0027] The above description is only the optimal solution embodiment of this utility model and is not intended to limit this utility model. Various modifications or substitutions made by those skilled in the art to this utility model without departing from the essence and protection scope of this utility model should also be within the protection scope of this utility model.
