Description

Technical Field

[0001] This utility model relates to the field of bottle cap surface coating technology, and in particular to a positioning fixture for vacuum coating of bottle cap surface. Background Technology

[0002] In the packaging industry, bottle caps are an important part of the product, and their appearance and quality have a significant impact on the product image. Vacuum coating technology, due to its environmental friendliness and ability to present a unique luster and texture, has been widely used in the surface treatment of bottle caps. It evaporates and deposits metallic or non-metallic materials on the surface of the bottle cap to form a uniform film with specific properties, which can significantly improve the aesthetics, wear resistance and corrosion resistance of the bottle cap.

[0003] After the bottle caps are processed, they are arranged from top to bottom on the outside of the hooks. After hanging, the hooks are placed on the rack, and finally the rack is pushed into the coating chamber to coat the bottle caps using a vacuum method.

[0004] Existing positioning fixtures for vacuum coating on bottle cap surfaces are designed so that each fixture corresponds to only one type of bottle cap. When coating bottle caps of different diameters, different fixtures need to be changed, which is a cumbersome process. They lack the ability to adapt to a variety of bottle caps with a single fixture. Furthermore, they lack the ability to rotate and fix bottle caps when coating bottle caps of different shapes. Therefore, a positioning fixture for vacuum coating on bottle cap surfaces is proposed. Utility Model Content

[0016] (III) Beneficial Effects

[0017] This utility model provides a vacuum coating positioning fixture for bottle caps. It has the following advantages:

[0018] 1. The bottle cap is fixed by the internal support mechanism. Insert the bottle cap opening into the hollow rubber column and manually push the fixing block outward. After the fixing block moves to the appropriate position, release the pushing force applied to the fixing block. At this time, the limiting block is stuck inside the fixing block. Under the action of the first spring, the limiting block is kept in an outward state, thus restricting the fixing block to a fixed position. At this time, due to the movement of the fixing block, the middle part of the hollow rubber column expands outward. The expanded part is in close contact with the inside of the bottle cap, thus fixing the bottle cap. The remaining bottle caps are fixed in the same way. This has the function of quickly fixing bottle caps, improving the installation speed of bottle caps, thereby improving the coating efficiency of bottle caps.

[0019] 2. The adjustment mechanism facilitates the adjustment of irregular bottle cap angles. Manually push the slip ring towards the hanging rod, and the slip ring will cause several locking blocks to move out of the first locking slot of the rotating rod and into the first locking slot of the horizontal column. Manually rotate the rotating rod to rotate the bottle cap fixed by the inner support to a suitable angle. After completion, remove the force applied to the slip ring, and under the action of the second spring, push the slip ring in the opposite direction to make the locking blocks lock into the first locking slot of the rotating rod. This mechanism can adjust the rotation angle of irregular bottle caps and can accommodate more bottle cap coatings. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present utility model. This embodiment provides a vacuum coating positioning fixture for bottle cap surface, including a hanging rod 1. Several adjustment mechanisms 3 are evenly distributed from top to bottom on the outer surface of the hanging rod 1, and an inner support mechanism 2 is provided on one side of the adjustment mechanism 3.

[0031] The internal support mechanism 2 includes a rotating rod 201. A hollow rubber column 203 is fixedly installed at one end of the rotating rod 201. A fixing block 202 is symmetrically installed on one side of the hollow rubber column 203. A first spring 204 is symmetrically arranged inside the rotating rod 201. A limit block 205 is fixedly connected to one side of the first spring 204. A push plate 209 is arranged inside the fixing block 202. A guide block 207 is fixedly connected to the bottom of the push plate 209.

[0032] Specifically, the bottle cap opening is placed on the hollow rubber column 203, and the fixing block 202 is manually pushed towards the bottle cap. After the fixing block 202 is pushed to the appropriate position, the limiting block 205 is locked inside the fixing block 202 under the action of the first spring 204. When the fixing block 202 is pushed outward, the middle part of the hollow rubber column 203 expands outward, and the expanded part supports the inner side of the bottle cap to fix the bottle cap in an internal support manner.

[0033] Specifically, the hollow rubber column 203 is sleeved on the outside of the rotating rod 201. The outer surface of the rotating rod 201 is symmetrically provided with circular grooves that are adapted to the first spring 204. The limiting block 205 is slidably connected inside the circular groove. Under the action of the first spring 204, an outward pushing force is applied to the limiting block 205, so that the limiting block 205 always remains in an outward state.

[0034] Specifically, the inner surface of the fixing block 202 is symmetrically provided with grooves 208 that are adapted to the push plate 209. The push plate 209 is slidably connected inside the grooves 208. Under the action of the grooves 208, the push plate 209 can move back and forth stably when it moves, preventing the push plate 209 from deviating during the movement.

[0035] Specifically, a push rod 206 is fixedly connected to one side of the push plate 209. The push rod 206 is movably inserted into the inside of the fixed block 202. The guide block 207 is adapted to the limiting block 205. When the push rod 206 pushes the push plate 209 toward the limiting block 205, the push plate 209 pushes the limiting block 205 completely into the rotating rod 201. At this time, the guide block 207 contacts the outer surface of the rotating rod 201. When the fixed block 202 moves in the opposite direction, another limiting block 205 will be slowly pushed into the rotating rod 201 along the inclined surface of the guide block 207, so that the fixed block 202 can move in the opposite direction.

[0036] Next, place the bottle cap onto the hollow rubber column 203, and manually push the fixing block 202 toward the bottle cap. After the fixing block 202 is pushed to the appropriate position, the fixing block 202 will expand the middle part of the hollow rubber column 203 outward, and the expanded part will be tightly attached to the inside of the bottle cap. At this time, the limiting block 205 is stably locked inside the fixing block 202 under the action of the first spring 204, fixing the fixing block 202 in this position. Fix the remaining bottle caps in the same way, and finally coat the bottle caps.

[0037] Example 2

[0038] Reference Figure 2 , Figure 5 and Figure 6 This is the second embodiment of the present invention, which is based on the previous embodiment and includes an adjustment mechanism 3 that facilitates flipping irregular bottle caps at a certain angle.

[0039] The adjustment mechanism 3 includes a horizontal column 303 fixedly installed on the outer surface of the hanging rod 1. A slip ring 304 is movably installed on the outer side of the horizontal column 303. Several locking blocks 305 are circumferentially distributed on the inner surface of the slip ring 304. The outer surfaces of the horizontal column 303 and the rotating rod 201 are both provided with first slots 302 that are adapted to the locking blocks 305. A T-shaped column 301 is fixedly connected to one side of the rotating rod 201. The T-shaped column 301 is rotatably connected to the inside of the horizontal column 303.

[0040] Specifically, by manually pulling the slip ring 304 in the opposite direction to the hanging rod 1, the slip ring 304 pulls several locking blocks 305 from the first locking groove 302 of the rotating rod 201 into the first locking groove 302 of the horizontal column 303, thereby rotating the rotating rod 201 to a suitable angle. Then, by moving the slip ring 304 in the opposite direction, the locking blocks 305 are locked into the first locking groove 302 of the rotating rod 201, thus fixing the rotating rod 201 and facilitating the adjustment of the bottle cap rotation angle.

[0041] Specifically, a limiting ring 307 is fixedly installed on the outer surface of the horizontal column 303. The limiting ring 307 is located inside the slip ring 304. A second spring 306 is provided on one side of the limiting ring 307. The second spring 306 is located on the opposite side of the slip ring 304 and the horizontal column 303. Under the action of the limiting ring 307, the slip ring 304 is prevented from disengaging from the outside of the horizontal column 303 when it moves, thus limiting the stable movement of the slip ring 304. Under the action of the second spring 306, a thrust is applied to the slip ring 304 in the direction of the rotating rod 201. A T-shaped groove adapted to the T-shaped column 301 is opened at the center of one side of the horizontal column 303. The T-shaped column 301 is rotatably connected in the T-shaped groove.

[0042] Furthermore, manually push the slip ring 304 toward the hanging rod 1. At this time, the slip ring 304 drives several locking blocks 305 to move out of the first locking slot 302 of the rotating rod 201. Move the locking blocks 305 into the first locking slot 302 of the horizontal column 303. Manually rotate the rotating rod 201 to adjust the bottle cap to a suitable angle. Then, remove the thrust applied to the slip ring 304. Under the action of the second spring 306, push the slip ring 304 in the opposite direction to restore the locking blocks 305 to their original position, thereby fixing the rotating rod 201.

[0043] Working principle: The open end of the bottle cap is secured to the hollow rubber column 203. Then, the fixing block 202 is manually pushed towards the bottle cap, causing it to press the hollow rubber column 203 inwards. This causes the middle portion of the hollow rubber column 203 to expand outwards, tightly adhering to the inner surface of the bottle cap. At this point, the limiting block 205, under the action of the first spring 204, is locked inside the fixing block 202, thus securing the bottle cap internally. Using the same method, the remaining bottle caps are secured to one side of the hanging rod 1 from top to bottom. After this, the hanging rod 1 is suspended on the rack. Once the rack is full of bottle caps, the coating chamber is pushed in for vacuum coating. After coating, the push rod 206 is manually pressed, pushing the push plate 209 towards the limiting block 205, fully pushing the limiting block 205 into the rotating rod 201. At this point, the guide block 207 adheres to the outer surface of the rotating rod 201, pushing the fixing block 202 in the opposite direction. With the assistance of the inclined surface of the guide block 207, the limiting block 205 in contact with the guide block 207 is pushed into the rotating rod 201 by the inclined surface. After the hollow rubber column 203 is fully extended, the bottle cap can be removed from the hollow rubber column 203. The remaining bottle caps can be removed in the same way. When coating bottle caps of different shapes, it is necessary to rotate the bottle caps fixed on the outside of the hollow rubber column 203 by a certain angle. At this time, manually push the slip ring 304 in the opposite direction of the hanging rod 1. The slip ring 304 moves the locking block 305 out of the first slot 302 of the rotating rod 201 and into the first slot 302 of the horizontal column 303. After rotating the rotating rod 201 by a certain angle, the first slot 302 of the rotating rod 201 is aligned with the opening of the first slot 302 of the horizontal column 303. The force applied to the slip ring 304 is removed. Under the action of the second spring 306, the slip ring 304 is pushed in the opposite direction, so that the locking block 305 returns to its original position.

[0044] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
