Description

Technical Field

[0001] This utility model relates to a combined clamp used in the spraying process of cup lids. It is designed with a clamp for fixing the mouth of the cup lid and a transfer clamp for quick-release engagement with the mouth clamp. The quick-release engagement relationship allows the clamp to be used while a shielding structure is designed to prevent the clamp from sticking. Background Technology

[0002] The surface coating of cup lids often uses electrostatic powder coating. In this process, the coated cup lids need to be transferred to a high-temperature curing oven for powder melting and curing. This requires a transfer operation from the coating station to the high-temperature curing oven. This necessitates avoiding the situation where residual plastic powder cures and causes the clamps to stick and become unremovable. Therefore, the clamps should support quick release to meet the process and operation requirements. Utility Model Content

[0003] The purpose of this utility model is to provide a spraying fixture assembly for a cup lid. The technical problem to be solved is to design a quick-release structure for spraying a cup lid while avoiding the solidification of plastic powder on the fixture assembly.

[0004] A cup lid spraying fixture assembly includes a mouth clamp and a transfer clamp that can be quickly detached and assembled with each other; the outer side of the mouth clamp has a first shielding cover, and the outer side of the transfer clamp has a second shielding cover. The combination of the first shielding cover and the second shielding cover prevents the plastic powder from adhering to the mouth clamp and the transfer clamp. The transfer clamp has protruding ribs on the surface that engages with the mouth clamp to reduce the contact area between the two.

[0005] The mouth clamp has an insertion hole inside, and the transfer clamp has a protruding insertion protrusion at the corresponding position. The insertion protrusion and the insertion hole correspond to form a quick-release assembly.

[0006] The first shield is a hollow cylindrical shaft structure that completely wraps the outer part of the mouth clamp, and the mouth of the cup lid is fixed in the gap between the first shield and the mouth clamp; the second shield is a hollow cylindrical shaft structure that wraps the outside of the transfer clamp, and the bottom position of the first shield corresponds to the top position of the second shield.

[0007] Both the first and second shielding covers are silicone shielding covers.

[0008] The transfer fixture includes a lifting component and a transfer component; the lifting component has a base and a support rod; a plug-in protrusion and a rib are arranged on the base, and the top of the support rod has a support part, the shape of which corresponds to the bottom position of the base and remains independent of each other.

[0009] The base has a limiting part and a gripping part. The limiting part is located above the gripping part. Insertion protrusions and ribs are fixed to the limiting part. The limiting part is in limiting cooperation with the guide cylinder of the transfer component. The limiting part is movably and vertically arranged inside the guide cylinder. The bottom of the gripping part cooperates with the support part.

[0010] The second shielding cover has an upper shielding cover and a lower shielding cover, wherein the upper shielding cover completely covers the outer part of the base, and the lower shielding cover covers the outer part of the guide cylinder.

[0011] The transfer component has a fixed rod that penetrates the interior of the guide cylinder and engages with it. The fixed rod has a long, longitudinally extending groove at its bottom. A support rod has a through-hole at its engagement point with the groove. The fixed rod is also fitted with a lifting flange, which also has a through-hole. Pins are installed in both the support rod's and the lifting flange's through-holes, engaging with the groove. The lifting flange is positioned between two gapped lifting rails. The lifting rails have internal grooves that slide with the pins, allowing the support rod to move up and down.

[0012] The raised ribs are arranged in a radiating pattern on the top of the base.

[0013] The lifting flange is an integral round cap structure.

[0014] The beneficial effects of this utility model are as follows: by designing the mouth clamp and the transfer clamp as quick-release structures, the entire mold assembly can be quickly disassembled; by designing the first shielding cover and the second shielding cover, plastic powder residue is prevented from remaining on the outer surface of the mold assembly, making it less prone to adhesion and thus easier to disassemble; by designing the ribs, the mouth clamp and the transfer clamp are less prone to adhesion to each other due to the reduction of the mating surface; by designing the transfer clamp as a two-part structure of lifting component and transfer component, and matching it with lifting rail, lifting flange and other components, the lifting component can automatically lift relative to the transfer component, thus facilitating fully automated operation, realizing automatic transfer between the spraying station and the high-temperature curing oven without manual intervention, making the transfer automatic and continuous, thereby improving production efficiency and equipment utilization.

[0031] Example 1

[0032] Please refer to Figures 1 to 2The figure shows a spraying fixture assembly for a cup cap, mainly designed with a synchronously rotatable mouth clamp 1 and a transfer clamp 2. The mouth clamp 1 is used to fix the bottle cap, facilitating spraying. The mouth clamp 1 is detachable, specifically mounted on top of the transfer clamp 2 using a plug-in method. Specifically, the mouth clamp 1 has a plug-in hole 11 inside, and the transfer clamp 2 has a corresponding protruding plug-in protrusion 211. This protrusion 211 corresponds to the plug-in hole 11, forming a quick-release assembly. After spraying at the spraying station in the spray booth, the mouth clamp 1, along with the container, can simply be pulled out and placed onto the fixture inside the high-temperature curing oven, thus supporting quick assembly and disassembly. The fixture inside the high-temperature curing oven and the transfer clamp 2 have the same plug-in interface. The transfer clamp 2 is connected to a rotating shaft on the spraying conveyor line, allowing it to move along with the spraying conveyor line and rotate with the shaft.

[0033] The outer sides of the mouth clamp 1 and the transfer clamp 2 are respectively fitted with a first shielding cover 3 and a second shielding cover 4 made of silicone material, as shown in the figure. The first shielding cover 3 adopts a hollow cylindrical shaft structure, which completely wraps the outer part of the mouth clamp 1, and the mouth of the cup lid 8 is fixed in the gap between the first shielding cover 3 and the mouth clamp 1. The second shielding cover 4 is a hollow cylindrical shaft structure, which wraps the outer part of the transfer clamp 2. The outer wrapping can be a one-piece wrapping or a two-part wrapping, as shown in the figure, which adopts a two-part wrapping. The bottom position of the first shielding cover 3 corresponds to the top position of the second shielding cover 4, so as to minimize the adhesion area of ​​the plastic powder. The surface of the above-mentioned silicone material is not easy to adhere to the plastic powder, thus forming a double shielding combination, which has good anti-sticking performance. Of course, other materials can also be used in practical applications. Meanwhile, the top surface of the second shield 4 is provided with several radiating protruding ribs 212, which can reduce the contact area with the mouth clamp 1 and more effectively prevent the clamps from sticking together after the residual plastic powder solidifies.

[0034] Example 2

[0035] Please refer to Figures 3 to 7 This embodiment is based on embodiment 1. In order to facilitate the fully automated operation of the process, eliminate manual transfer between the spraying station and the high-temperature curing oven, realize the automated and continuous operation of the transfer, and improve production efficiency and equipment utilization, the specific improvements in this embodiment are as follows: First, a lifting track 7 is added to the spraying conveyor line. At the same time, the transfer fixture 2 is optimized, and components such as the lifting flange 6 are added.

[0036] As shown in the figure, both the mouth clamp 1 and the first shield 3 can adopt the style of Embodiment 1.

[0037] The second shielding cover 4 used in this embodiment adopts a split structure, which has an upper shielding cover 41 and a lower shielding cover 42. The upper shielding cover 41 completely covers the outer part of the base 213 of the transfer fixture 2, and the lower shielding cover 42 covers the outer part of the guide cylinder 221 of the transfer fixture 2. In this way, when the support rod 214 of the transfer fixture 2 is raised, the upper shielding cover 41 can also cover the outer wall of the base 213.

[0038] The transfer fixture 2 in this embodiment has a lifting component 21 and a transfer component 22. The transfer fixture 2 in this embodiment consists of two separate, relatively movable components. The transfer fixture 2 in embodiment 1, however, is a single component without relative movement. The choice between these components depends on the application scenario. In practical applications, the transfer fixture 2 can also be referred to as the transfer component 22, with the lifting component 21 added as an additional component. The transfer component 22 encloses the lifting component 21, ensuring stable lifting. After being lifted, the lifting component 21 is gripped by a gripper or robotic arm, allowing the base 213 of the lifting component 21, along with the mouth clamp 1 and the bottle cap, to be transferred to a fixture inside the high-temperature curing oven, eliminating the need for manual transfer. The transfer component 22 is connected to a rotating shaft on the spraying conveyor line, allowing it to move along with the spraying conveyor line and rotate with the rotating shaft.

[0039] The aforementioned lifting component 21 is designed with a base 213 and a support rod 214. The base 213 is designed with a limiting part 2131 and a gripping part 2132. The limiting part 2131 is located above the gripping part 2132 and protrudes laterally, engaging with the upper end of the guide cylinder 221 of the transfer component 22 for limiting its position and ensuring that the limiting part 2131 is movably and vertically arranged inside the guide cylinder 221. The gripping part 2132 is a hollow cylindrical structure. The bottom of the gripping part 2132 contacts the support part 2131 at the top of the support rod 214, thus forming a corresponding shape and maintaining an independent and non-fixed assembly relationship. In this way, the base 213 can be freely removed and placed from the support part 2131. The gripping part 2132 is movably and vertically arranged within the internal cavity of the guide cylinder 221 of the lifting component 21. That is, the gripping part 2132 can be exposed upward outside the guide cylinder or hidden downward inside the guide cylinder. When exposed upward outside the guide cylinder 221, the gripper or robot arm can grip the gripping part 2132 and transfer the base 213 together with the mouth clamp 1 and the bottle cap to the clamp in the high-temperature curing oven. As shown in the figure, the insertion and removal protrusion 211 and the protrusion rib 212 are both arranged on the base 213. In the figure, the protrusion rib 212 is arranged in a radiating shape on the top of the base 213.

[0040] In this embodiment, the transfer component 22 includes a fixing rod 222 and a guide cylinder 221. The fixing rod 222 is connected to the rotating shaft of the spraying conveyor line and has a hollow cylindrical structure. It penetrates the interior of the guide cylinder 221 and is assembled with it. The fixing rod 222 has a long, longitudinally penetrating groove 2221 at its bottom, which is assembled with a subsequent pin 5. The pin 5 is also assembled with a support rod 214. Specifically, the support rod 214 has a through-hole 2142 at the position where it mates with the groove 2221, and the through-hole 2142 is assembled with the pin 5. The guide cylinder 221 is a conventional hollow cylindrical structure, which limits the position of the support rod 214 and fixes the fixing rod 222.

[0041] To ensure the smooth movement of the entire transfer clamp 2 on the lifting rail 7, a lifting flange 6 is fitted onto the aforementioned fixed rod 222. The lifting flange 6 has a round cap structure and is designed with an insertion hole 2142 that penetrates the entire side wall of the lifting flange 6. A pin 5 is inserted into the insertion hole 2142 of the lifting flange 6, the insertion hole 2142 of the support rod 214, and the sliding groove 2221 of the fixed rod 222. This pin 5 keeps the lifting flange 6 and the support rod 214 in a fixed assembly and allows it to slide within the sliding groove 2221. The lifting flange 6 is positioned between two lifting rails 7 with a gap. The lifting rails 7 have an inner groove 71 that slides with the pin 5. Because the lifting rails 7 are designed with a height difference in their lifting trajectory, when the combined clamp moves from the lower part of the lifting rails 7 to the higher part, the lifting flange 6 can drive the support rod 214 upwards, causing the base 213 to rise and protrude from the guide cylinder 221 for easy gripping.
