Description

Technical Field

[0001] The utility model belongs to the technical field of cosmetic production equipment, and particularly relates to an adaptive capping machine for cosmetic container bottles. Background Art

[0002] At present, there are more and more categories of cosmetics, and the classification is becoming more and more detailed. Cosmetic containers are used to package cosmetics and are usually made of materials such as plastic or glass. Cosmetics are in liquid or paste form. After the production of cosmetics is completed, the cosmetic containers will be filled in sequence. After filling, they need to be screwed with lids to prevent the cosmetics inside from leaking out of the bottle mouth due to tilting or inversion of the cosmetic containers during shipment and transportation. In the past production process, there were special capping machines for screwing lids into the bottle mouths of cosmetic containers for mass production. However, since it is impossible for factories to have only one specification of cosmetic containers during production, different lids will be screwed into different cosmetic containers. The current capping machines need to be manually adjusted for different sizes of lids. The process is cumbersome, and if the adjustment is not in place, the lids will not be screwed on, or the force of clamping the lids will be too large, resulting in subsequent rework and affecting production progress. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides an adaptive capping machine for cosmetic container bottles. By setting a matching groove for matching sample caps on the capping assembly, the sample caps and the caps to be screwed are of the same specifications. Therefore, after the sample caps are placed, the rotating wheel component will abut against the sample caps during the advancement process, and its lower end will also just clamp the cap, driving the sample cap to rotate so that the cap at the lower end is rotated and screwed into the container bottle. For caps of different specifications, the same sample caps are placed in the matching groove to achieve adaptive matching capping.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] The machine is equipped with a plurality of control wheels, each of which is connected to the control wheel to control the rotation of the control wheel, and the control wheel is connected to the control wheel to control the rotation of the control wheel.

[0006] The rotating wheel component includes a first cylinder, a hollow tube and a rotating shaft, the first cylinder is arranged on a support plate, the output end of the first cylinder is connected to the hollow tube, the hollow tube passes through the long hole on the support plate up and down, and bearings are provided at the upper and lower ends of the hollow tube, the rotating shaft is coaxial with the hollow tube and embedded in the bearings at the upper and lower ends, and the upper and lower ends of the rotating shaft are respectively provided with a first roller and a second roller, the first roller is abutted and connected to the outer wall of the sample cover under the drive of the first cylinder, and the second roller is abutted and connected to the outer wall of the cover under the drive of the first cylinder; the hollow tube and the rotating shaft include two groups, the two groups of hollow tubes are vertically arranged and parallel to each other; the rotating wheel component includes two groups, the two groups of rotating wheel components are symmetrically arranged on the support plate with the adapting component as the symmetry center, the four groups of first rollers on the two groups of rotating wheel components are circumferentially distributed on the outer wall of the sample cover, and the four groups of second rollers on the two groups of rotating wheel components are circumferentially distributed on the outer wall of the cover.

[0007] The adapter component includes a bearing seat and a support seat, the bearing seat is arranged on the support plate, the lower end of the support seat is embedded in the bearing seat, the upper end of the support seat is provided with a matching groove, and the sample cover is placed in the matching groove; the adapter component also includes a fixed seat, a second cylinder, a push plate, a rotating motor and a butt joint, the fixed seat is a "X"-shaped structure, the bottom of the fixed seat is detachably connected to the support plate, the second cylinder is arranged on the fixed seat, the output end of the second cylinder passes through the fixed seat and is connected to the push plate, a rotating motor is provided on the push plate, the output end of the rotating motor passes through the push plate and is connected to the butt joint, and the butt joint is driven by the second cylinder to make a butt connection with the top end of the sample cover.

[0008] The adaptive capping machine for cosmetic container bottles adopts this structure. After the container bottle has the cap to be screwed in pre-placed at its bottle mouth in the previous process, it is conveyed by a conveyor belt into the clamping area surrounded by two sets of clamping components. In order to enable the container bottle to stay at a predetermined position, this can be achieved through the start and stop of the detection head and the conveyor belt. Since this content is existing technology, how the conveyor belt is driven is also existing technology, so how it is achieved will not be described in detail here. The container bottle is clamped, fixed and straightened during the simultaneous start-up of the two groups of clamping components. In order to clamp the lid placed on the container bottle, two groups of rotating wheel components are set on the frame. The first cylinder on the rotating wheel component pushes the two groups of vertically arranged hollow tubes to move horizontally in the long hole. The coaxial rotating shaft in the hollow tube can rotate in the hollow tube due to the setting of the bearing. The second roller at the lower end of the rotating shaft, when the two groups of first cylinders are started at the same time, the four groups of second rollers will simultaneously abut against the outer wall of the lid to clamp the lid. At the same time, the four groups of first rollers will also clamp the sample placed in the matching groove on the support seat. The outer wall of the lid, since the sample lid and the lid are of the same size, the second roller will also clamp the lid just right when the first roller stably clamps the sample lid. In order to drive the lid to be screwed into the bottle mouth of the container bottle, the second cylinder on the fixed seat pushes the push plate to move downward, so that the abutment head abuts against the upper end of the sample lid, clamping the sample lid between the abutment head and the support seat, and the lower end of the support seat is embedded in the bearing seat. Therefore, when the rotating motor is started, the sample lid will rotate, thereby driving the rotating shaft, linking to the second roller, and synchronously driving the lid to rotate, thereby screwing the lid into the bottle mouth of the container bottle.

[0009] Therefore, the working method of the adaptive capping machine is to randomly select one of the caps that need to be screwed in as a sample cap, place it with its opening downward in the matching groove, and there is no need to adjust the position, just embed it in the matching groove, start the two groups of first cylinders, and simultaneously push the two groups of hollow tubes toward the sample cap, so that the four groups of first rollers are circumferentially distributed and abut against the outer wall of the sample cap, and the sample cap is pre-pushed by the four groups of first rollers in the transverse direction to achieve the correct position of the tube in the matching groove, and then drive the second cylinder to move the abutment downward and abut against the upper end face of the sample cap, so that the sample cap is abutted and clamped in the matching groove by the abutment, so as to fix the position of the sample cap, and then drive the two groups of first cylinders back to their original position, disengaging the abutment between the four groups of first rollers and the sample cap, so as to prepare for the start of batch capping.

[0010] The container bottles with the caps placed in advance enter the area where the two groups of clamping components are located under the conveyor belt. The two groups of clamping components start at the same time and clamp the container bottles. After ensuring that the container bottles are fixed, the first cylinder is driven to push the two groups of hollow tubes. The four groups of second rollers at the lower end of the rotating shaft in the hollow tube abut against the outer wall of the cap, and the four groups of first rollers at the upper end of the rotating shaft also abut against the outer wall of the sample cap at the same time. Since the cap and the sample cap are of the same size, the cap can be clamped exactly. At this time, the rotating motor is started to drive the abutment head to drive the sample cap to move on the support The sample cap in the rotation process will drive the first roller of the four sets of abutment processes to rotate, so the second roller will also rotate synchronously, thereby driving the cap to rotate and screw it into the bottle mouth of the container bottle. After the capping is completed, the first cylinder and the clamping assembly are driven to return to their original position, and the conveyor belt is started to send the container bottles with completed capping to the next process. Subsequent container bottles can be capped in batches under the continuous drive of the conveyor belt. When different caps need to be replaced, repeated operations can be performed for quick adaptation, which saves time and effort and is simple to operate.

[0011] Furthermore, the clamping assembly includes a third cylinder and a clamping head, the third cylinder is arranged on the frame, the output end of the third cylinder is connected to the clamping head, and the end of the clamping head is an arc structure; the frame is also provided with a stud, the support plate passes through the stud, and the upper and lower end surfaces of the support plate are respectively fixed by two nuts screwed on the stud; a clamping rail is provided above the conveyor belt, and the container bottle is fitted in the clamping rail.

[0012] Compared with the prior art, the advantages of the present invention are: among the caps of the same specification that need to be screwed together, any one of them can be selected as a sample cap, and before the capping machine performs batch capping, the sample cap is used as a basic clamping member, and during the synchronous clamping, it can ensure that the lower cap can be just clamped, and will not cause empty clamping or excessive clamping, and the sample cap is driven to rotate to provide rotational force for the cap, thereby ensuring that the cap can be smoothly screwed into the bottle mouth of the container bottle, realizing batch automatic capping, and when different caps need to be replaced, repeated operations can be performed for quick adaptation, which saves time and effort and is simple to operate.

[0027] Description of the working method of this utility model:

[0028] The adaptive capping machine for cosmetic container bottles adopts this structure. After the container bottle 5 has a cap 6 to be screwed in pre-placed at its bottle mouth in the previous process, it is conveyed by the conveyor belt 2 into the clamping area surrounded by two sets of clamping components 3. In order to enable the container bottle 5 to stay at a predetermined position, this can be achieved through the start and stop of the detection head and the conveyor belt 2. Since this content is existing technology, how the conveyor belt 2 is driven is also existing technology, so how it is achieved will not be repeated here. The second roller 426 at the lower end of the rotating shaft 423 can abut the outer wall of the lid 6 on the container bottle 5 when the two sets of first cylinders 421 are started at the same time, and the four sets of second rollers 426 will simultaneously abut the outer wall of the lid 6, thereby clamping the lid 6 on the container bottle 5. The second roller 426 also clamps the lid 6 just right while the first roller 425 is clamping the sample lid 7. In order to drive the lid 6 to be screwed into the bottle mouth of the container bottle 5, the second cylinder 435 on the fixed seat 434 pushes the pushing plate 436 to move downward, so that the abutment 438 abuts against the upper end of the sample lid 7, clamping the sample lid 7 between the abutment 438 and the support seat 432. The lower end of the support seat 432 is embedded in the bearing seat 431. Therefore, when the rotating motor 437 is started, the sample lid 7 will rotate, thereby driving the rotating shaft 423, linking to the second roller 426, and synchronously driving the lid 6 to rotate, thereby screwing the lid 6 into the bottle mouth of the container bottle 5.

[0029] Therefore, the working method of the adaptive capping machine is to adjust the spacing of the clamping rails 21 so that the container bottles 5 on the conveyor belt 2 can be guided by the clamping rails 21 and enter the area between the two groups of clamping heads 32; by screwing the nuts 12 on the studs 11, adjust the upper and lower positions of the support plate 41 so that the second roller 426 can be located exactly at the position of the cap 6 placed on the container bottle 5; randomly select one of the caps 6 to be screwed in as a sample cap 7, place it with its opening downward in the matching groove 433, and there is no need to adjust the position, just insert it into the matching groove 433, start the two groups of first cylinders 421, and push the two at the same time. The hollow tube 422 is moved toward the sample cover 7, so that the four groups of first rollers 425 are circumferentially distributed against the outer wall of the sample cover 7. The sample cover 7 is pre-pushed by the four groups of first rollers 425 in the transverse direction so as to realize the correct position of the tube in the matching groove 433. Then the second cylinder 435 is driven to move the abutment 438 downward to abut against the upper end surface of the sample cover 7, so that the sample cover 7 is abutted and clamped in the matching groove 433 by the abutment 438, so as to fix the position of the sample cover 7. Then the two groups of first cylinders 421 are driven back to their original positions, disengaging the abutment between the four groups of first rollers 425 and the sample cover 7, so as to prepare for the start of batch screwing of the covers.

[0030] The container bottle 5 with the cap 6 placed in advance enters the area where the two groups of clamping assemblies 3 are located under the conveyance of the conveyor belt 2. The third cylinders 31 of the two groups of clamping assemblies 3 are started at the same time and clamp the container bottle 5 through the clamping head 32. The arc structure on the clamping head 32 can abut against the outer wall of the container bottle 5. After ensuring that the container bottle 5 is fixed, the first cylinder 421 is driven to push the two groups of hollow tubes 422. The four groups of second rollers 426 at the lower end of the rotating shaft 423 in the hollow tube 422 abut against the outer wall of the cap 6, and the four groups of first rollers 425 at the upper end of the rotating shaft 423 also abut against the outer wall of the sample cap 7 at the same time. Since the cap 6 and the sample cap 7 are of the same size, the cap 6 can be clamped just right. At this time, the rotating motor 437 is started to drive the abutment head 438 to drive the sample cover 7 to rotate on the support seat 432. The sample cover 7 in the rotation process will drive the first roller 425 in the four sets of abutment processes to rotate, so the second roller 426 will also rotate synchronously, thereby driving the cover 6 to rotate and screw it into the bottle mouth of the container bottle 5. After the capping is completed, the first cylinder 421 and the clamping assembly 3 are driven to return to their original positions, and the conveyor belt 2 is started to send the container bottles 5 with completed capping to the next process. Subsequent container bottles 5 can be capped in batches under the continuous drive of the conveyor belt 2. When different caps 6 need to be replaced, repeated operations can be performed to quickly adapt, saving time and effort and simple operation.

[0031] The beneficial effect of the present invention is that: among the caps 6 of the same specification that need to be screwed together, any one of them can be selected as the sample cap 7. Before the capping machine performs batch capping, the sample cap 7 is used as the basic clamping member. During the synchronous clamping, it can be ensured that the lower cap 6 can be just clamped, which will not cause empty clamping or excessive clamping. In addition, by driving the sample cap 7 to rotate, a rotational force is provided to the cap 6, thereby ensuring that the cap 6 can be smoothly screwed into the bottle mouth of the container bottle 5, realizing batch automatic capping. When different caps 6 need to be replaced, repeated operations can be performed for quick adaptation, which saves time and effort and is simple to operate.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
