Abstract
Description
Technical Field
[0001] This utility model belongs to the field of thermos cup processing technology, and more specifically, it relates to a fine powder coating device for the surface of thermos cups. Background Technology
[0002] The powder coating on a thermos cup forms a dense polymer film that prevents the metal substrate from directly contacting the external environment, thus extending the lifespan of the thermos cup. The automatic powder coating device fixes the cup body with an interference fit clamp and rotates it at a uniform speed. Through the reciprocating motion of the spray gun in the vertical direction, it ensures that the coating on the outer surface of the thermos cup is evenly covered. Compared with traditional manual spraying, it is more refined. The existing automatic powder coating device generally consists of an operating table, a material storage machine for storing powder coating raw materials, a spray arm that slides up and down, a spray gun, a ring clamp that fixes the thermos cup with an interference fit from the inner wall of the thermos cup, and a lifting electric cylinder that lifts the thermos cup after powder coating.
[0003] Based on the above, when the model of the thermos cup changes, resulting in a change in the inner wall diameter, the size of the annular clamp that is interference-fitted with the inner wall diameter must be strictly matched, and the stroke of the piston rod of the lifting electric cylinder must also meet the height change of the new clamp. Therefore, the inner wall annular clamp and the lifting electric cylinder need to be replaced simultaneously. The overall replacement of the clamp and the electric cylinder is costly and requires professional personnel to operate, making it highly dependent on technology. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a fine powder coating device for the surface of a thermos cup. This device addresses the issue that when the inner diameter of the thermos cup changes due to a model change, the dimensions of the annular clamp that is interference-fitted with the inner diameter must be strictly matched, and the stroke of the piston rod of the lifting cylinder must also meet the height change of the new clamp. Therefore, the inner annular clamp and the lifting cylinder must be replaced simultaneously. The overall replacement of the clamp and cylinder is costly and requires professional personnel to operate, making it highly dependent on technical expertise.
[0005] The purpose and effect of this utility model's fine powder coating device for the surface of a thermos cup are achieved by the following specific technical means:
[0006] A fine powder coating device for the surface of a thermos cup includes an operating table, a material storage machine, a spraying arm, a spray gun, a rotary electric cylinder, a support plate, an annular component, a thermos cup workpiece, lifting columns, a knob, a separation component, and an adjustment component.

The thermos cup workpiece is sleeved on the outside of the annular component. Three lifting columns are provided, with the bottom lifting column fixedly connected to the piston rod end of the rotary electric cylinder, and the top two lifting columns located above the bottom lifting column. The knob is rotatably connected to the right end of the spraying arm. The separation component is located above the operating table.

[0007] Furthermore, the separation component includes: a limiting box, a sliding paddle, and a limiting plate; the limiting box is fixedly connected inside the support plate; the sliding paddle is slidably connected inside the limiting box; and the limiting plate is fixedly connected behind the sliding paddle.
[0008] Furthermore, the separation assembly also includes: a reset spring and a plug block; the rear end of the reset spring is fixedly connected to the rear of the sliding paddle, and the front end of the reset spring is fixedly connected to the inside of the limiting box; the plug block has a square slot inside, the plug block is inserted into the inside of the support plate, and the plug block is fixedly connected to the bottom of the annular part.
[0009] Furthermore, the separation component also includes: square pillars and square slots; two square pillars are provided, and the two square pillars are respectively fixedly connected to the bottom and middle lifting pillars; two square slots are provided, and the two square slots are respectively provided inside the two top lifting pillars.
[0010] Furthermore, the separation assembly also includes a threaded post and a contact element; the threaded post is fixedly connected to the top lifting post; the contact element is threadedly connected to the outside of the threaded post.
[0011] Furthermore, the adjustment assembly includes: a transmission worm gear, a connecting shaft, a transmission worm wheel, and a fixing component; the transmission worm gear is coaxially and fixedly connected to the front end of the knob; the connecting shaft is rotatably connected to the inside of the right end of the spray arm; the transmission worm wheel is coaxially and fixedly connected to the bottom of the connecting shaft, and the transmission worm wheel meshes with the transmission worm gear; the fixing component is fixedly connected to the top of the connecting shaft, and the fixing component is fixedly connected to the bottom of the spray gun.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] First, the ring-shaped part used to match the inner diameter of the thermos cup adopts a separate detachable and replaceable design, which has a low technical threshold and can be easily operated by ordinary workers. The lifting column used to lift the thermos cup adopts a separate plug-in design, which can be plugged in with the original lifting column to achieve height adjustment. The overall design saves time and effort and has a low cost.
[0014] Secondly, if it is necessary to fine-tune the spray angle of the spray gun to obtain a better spraying effect, the operator only needs to rotate the knob to drive the connecting shaft and the fixing part to rotate together, thereby changing the spray angle of the spray gun. Thanks to the self-locking characteristics of the worm gear transmission mechanism, even if the equipment vibrates during operation, the spray angle of the spray gun will not shake or change, ensuring the accuracy and stability of the spraying angle.
[0015] The annular component of this invention features a separate detachable design, allowing for quick matching with the inner diameter of the thermos cup. It is easy to operate. The lifting column uses a separate plug-in design, which can be used with the original lifting column to achieve raising. This effectively improves the flexibility and economy when dealing with changes in thermos cup models. The spray gun angle can be easily and finely adjusted, reducing overall operating and maintenance costs and improving production efficiency and product quality. Attached Figure Description

[0026] As attached Figure 1 To be continued Figure 6 As shown:
[0027] This utility model provides a fine powder coating device for the surface of a thermos cup, including an operating table 1, a storage machine 2, a spraying arm 3, a spray gun 301, a rotating electric cylinder 4, a support plate 5, an annular component 6, a thermos cup workpiece 7, lifting columns 11, a knob 15, and a separation assembly; the storage machine 2 is fixedly connected to the left side of the operating table 1; the spraying arm 3 is slidably connected to the upper end of the storage machine 2; the spray gun 301 is located at the right end of the spraying arm 3; the rotating electric cylinder 4 is rotatably connected to the operating table 1; the support plate 5 is fixedly connected to the top of the rotating electric cylinder 4; the annular component 6 is located on the support plate 5; the thermos cup workpiece 7 is sleeved on the outside of the annular component 6; three lifting columns 11 are provided, the bottom lifting column 11 is fixedly connected to the piston rod end of the rotating electric cylinder 4, and the top two lifting columns 11 are located above the bottom lifting column 11; the knob 15 is rotatably connected to the right end of the spraying arm 3; the separation assembly is located above the operating table 1.
[0028] The separation component includes: a limiting box 8, a sliding paddle 9, and a limiting plate 901; the limiting box 8 is fixedly connected inside the support plate 5; the sliding paddle 9 is slidably connected inside the limiting box 8; and the limiting plate 901 is fixedly connected behind the sliding paddle 9.
[0029] The separation assembly also includes: a reset spring 902 and a plug block 10; the rear end of the reset spring 902 is fixedly connected to the rear of the sliding paddle 9, and the front end of the reset spring 902 is fixedly connected to the inside of the limit box 8; the plug block 10 has a square slot inside, the plug block 10 is inserted into the inside of the support plate 5, and the plug block 10 is fixedly connected to the bottom of the ring part 6.
[0030] The separation component also includes: a square column 1101 and a square slot 1102; two square columns 1101 are provided, and the two square columns 1101 are fixedly connected to the bottom and middle lifting columns 11 respectively; two square slots 1102 are provided, and the two square slots 1102 are respectively provided inside the two lifting columns 11 at the top.
[0031] The separation assembly also includes a threaded post 13 and a contact 14; the threaded post 13 is fixedly connected to the top lifting post 11; the contact 14 is threadedly connected to the outside of the threaded post 13.
[0032] The specific usage and function of this embodiment are as follows: During use, if the model of the thermos cup workpiece 7 changes or its inner diameter changes, move the sliding paddle 9 forward to disengage the limiting plate 901 from the square slot in the insertion block 10. Then, the annular part 6 can be lifted upwards. When the annular part 6 moves below the contact member 14, the contact member 14 is rotated down through the threaded engagement between the contact member 14 and the threaded post 13, facilitating the continued upward movement and removal of the annular part 6. After obtaining a new annular part 6, first, it is fitted onto the outside of the lifting post 11. The insertion blocks 10 at the bottom of different models of annular parts 6 are the same size. Then, move the sliding paddle 9 forward again to insert the insertion block 10 at the bottom of the new annular part 6 into the support plate 5. Release the sliding paddle 9 and return to the starting position. Under the rebound action of spring 902, sliding paddle 9 and limiting plate 901 move backward and insert into the square slot in the plug-in block 10, so that the new annular part 6 is fixed with the support plate 5. At the same time, if the new thermos cup workpiece 7 is too deep, the lifting column 11 cannot lift the thermos cup workpiece 7 when it is lifted by the piston rod of the rotating electric cylinder 4. In this case, a new lifting column 11 can be added. In specific operation, first pull out the topmost lifting column 11 upward, and then take a new lifting column 11 with the same shape as the middle lifting column 11. The new lifting column 11 is then inserted into the original lifting column 11 through the cooperation of square column 1101 and square slot 1102. Thus, the total height of multiple lifting columns 11 changes with the change of thermos cup workpiece 7 model.
[0033] Example 2:
[0034] Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 6 As shown, it also includes an adjustment component, which is located at the right end of the spray arm 3.

[0036] The specific usage and function of this embodiment: If it is necessary to fine-tune the spray angle of the spray gun 301 to achieve a better spraying effect, the knob 15 can be rotated. The worm gear transmission mechanism, which is formed by the meshing of the transmission worm wheel 1601 and the transmission worm 1501, drives the connecting shaft 16 and the fixing part 1602 to rotate, thereby changing the spray angle of the spray gun 301. At the same time, due to the self-locking characteristic of the worm gear transmission mechanism, the spray angle of the spray gun 301 will not be changed by the vibration of the equipment.
