Description

Technical Field

[0001] The utility model belongs to the technical field of labeling, and particularly relates to a device for pre-labeling bottle caps. Background Art

[0002] After the bottle caps are injection-molded, information about the corresponding bottle body or product needs to be posted and marked on their outer or inner surfaces, mainly including laser marking and attaching electronic tags. Laser marking technology mainly uses a laser beam to quickly scan the top or inner wall of the bottle cap and precisely engrave according to preset patterns, characters, two-dimensional codes, and other information; electronic tags usually integrate chips such as RFID and NFC, which can store and transmit more abundant and dynamic information. At a specific position reserved inside the bottle cap, the electronic tag is embedded through a precise labeling device.

[0003] However, after the bottle caps are injection-molded, they are usually stacked together. A common screening structure is a belt inclined at an angle, with protrusions provided on the belt. As the belt rotates, the protrusions continuously drive the bottle caps with their openings facing downwards to move upwards, and then they are collected. During this process, the bottle caps are continuously flipped until all the bottle caps are in a state with their openings facing downwards and are transported upwards by the belt. For some processes that require marking and labeling on the top of the inner wall of the bottle cap, the bottle caps with their openings facing downwards need to be flipped to have their openings facing upwards. Therefore, a device is provided to completely flip the bottle caps in preparation for marking and labeling the top of the inner wall of the bottle caps. Summary of the Utility Model

[0019] like Figures 1 to 4 The bottle cap pre-labeling device shown in the figure comprises a workbench 1, and hinge seats 2 are arranged on the front and rear sides of the top of the workbench 1, a flip rod 3 is rotatably connected between the hinge seats 2, a first receiving plate 5 is connected to the flip rod 3 through a first sleeve 4, and a first receiving groove 6 is opened on the first receiving plate 5, a cylinder 7 is arranged on the front side of the top of the workbench 1, and a push plate 9 is arranged on the telescopic end of the cylinder 7 through a connecting piece 8, and a mounting groove 10 is arranged on the left side of the push plate 9, and a rack 11 is arranged in the mounting groove 10, and a gear 12 is arranged on the flip rod 3 above the rack 11; the inner side of the hinge seat 2 is rotatable A second sleeve 13 is provided, a second receiving plate 14 is connected between the second sleeves 13, and a second receiving groove 15 is opened on the second receiving plate 14; the second sleeve 13 is movably sleeved on the flip rod 3; the length of the second receiving plate 14 is greater than that of the first receiving plate 5, and a connecting rod group 16 is connected between the front and rear sides of the first receiving plate 5 and the second receiving plate 14; a first clamping column 17 and a second clamping column 18 are provided on the inner side of the hinge seat 2; a slide rail 19 is provided at a position below the rack 11 on the top of the workbench 1, and a slider 20 is slidably arranged on the slide rail 19 to connect with the bottom of the rack 11.

[0020] The utility model realizes the collection of bottle caps with openings downward by setting a first receiving plate 5 flush with the output end of the feeding belt, and limits the turning of the bottle caps by the first receiving groove 6, and is also provided with a second receiving plate 14 whose length is greater than the first receiving plate 5. When the first receiving plate 5 rotates to turn the bottle caps, the upper part of the bottle caps can be limited by the second receiving plate 14, and then the first receiving plate 5 continues to rotate to push the second receiving plate 14 to rotate as well, until the second receiving plate 14 is located on the right side of the turning rod 3 and tilted downward, the turning of a large number of bottle caps is completed, the turning efficiency is improved, and the subsequent processing is convenient; a first clamping column 17 and a second clamping column 18 are also provided, and the first clamping column 17 and the second clamping column 18 can both resist the second receiving plate 14, cooperate with the rotation of the second receiving plate 14 to promote the turning of the bottle caps, avoid overload of the device, and effectively extend the service life of the device.

[0021] Example 2

[0022] like Figures 1 to 4The bottle cap pre-labeling device shown includes a workbench 1, which is used to carry all the components required for flipping, and the left side of the workbench 1 is connected to the feeding belt, and the right side is connected to the discharging belt, that is, the feeding belt transfers the bottle cap with the opening downward to the right onto the workbench 1, the workbench 1 flips the bottle cap until the opening is upward, and transfers the flipped bottle cap to the right to the discharging belt, and the discharging belt will continue to transfer to the right to cooperate with the marking inside the bottle cap.

[0023] Articulated seats 2 are provided on the front and rear sides of the top of the workbench 1, and a flip rod 3 is rotatably connected between the articulated seats 2. First sleeves 4 are symmetrically fixedly provided on the flip rods 3, and a first receiving plate 5 is connected between the first sleeves 4. The first receiving plate 5 is flush with the output end of the feeding belt and is used to receive the bottle caps with the opening downward; the first receiving groove 6 is opened on the first receiving plate 5, which drives the first receiving plate 5 to present a container with an opening on the left side, which is used to collect bottle caps. At this time, the bottle caps are opened downward.

[0024] The second sleeve 13 is rotatably provided on the inner side of the hinge seat 2, and the second sleeve 13 is also movably sleeved on the flip rod 3, so that the rotation of the flip rod 3 will only drive the first sleeve 4 and the first receiving plate 5 to rotate, and will not affect the rotation of the second sleeve 13; the second sleeve 13 is connected with the second receiving plate 14, and the second receiving plate 14 is provided with a second receiving groove 15, which also presents the first receiving plate 5 as a container with an opening on the left side. It should be noted that the first receiving groove 6 and the second receiving groove 15 are arranged relative to each other. When the first receiving groove 6 collects the bottle caps with the opening facing downward, the second receiving groove 15 is located above the first receiving groove 6. When the embodiment specifies that the length of the second receiving plate 14 is greater than that of the first receiving plate 5, the rotation of the second receiving plate 14 can be affected and driven by the first receiving plate 5.

[0025] like Figure 1 As shown, the second receiving plate 14 needs to be suspended above the first receiving plate 5 in its initial state, so the present application also provides a first clamping column 17 at the corresponding position of the hinge seat 2 to prevent the second receiving plate 14 from directly rotating to the left and blocking the first receiving groove 6, so that the bottle caps cannot enter. At this time, the first receiving plate 5 is aligned with the feeding belt, and the bottle caps with the openings downward will continue to accumulate and enter the first receiving groove 6. After the first receiving groove 6 is filled with accumulation, the feeding belt is stopped, and the turning rod 3 is driven to rotate and drive the first receiving plate 5 to rotate to the right until it contacts the second receiving plate 14, wherein the interval angle between the first receiving plate 5 and the second receiving plate 14 is small, and the bottle caps will not undergo unnecessary rotation when the first receiving plate 5 approaches the second receiving plate 14.

[0026] When the first receiving plate 5 continues to rotate to the right, it will push the second receiving plate 14 to rotate. At this time, the second sleeve 13 also rotates on the hinge seat 2. At this time, the bottle cap is located in the flipping cavity formed by the relative arrangement between the first receiving groove 6 and the second receiving groove 15, preventing the bottle cap from coming off. Considering that after the second receiving plate 14 rotates to the vertical state, it will directly rotate to the right under the influence of gravity, causing the bottle cap to also fall. A torsion spring (not shown in the drawing) is connected between the second sleeve 13 and the hinge seat 2. Thus, the second receiving plate 14 can always closely adhere to the first receiving plate 5 under the action of the torsion spring, limiting the bottle cap in the flipping cavity until the second receiving plate 14 rotates to the right and tilts downward.

[0027] The discharge belt can rotate continuously. When the second receiving plate 14 rotates to the right and tilts downward, it means that the first receiving plate 5 is above the second receiving plate 14 at this time. The bottle cap lies on the second receiving plate 14 with the opening facing upward, and the flipping is completed. At this time, the opening of the flipping cavity is also on the right side. The bottle cap that has completed the flipping slides naturally to the right along the second receiving plate 14 and falls onto the discharge belt. The discharge belt rotates to convey the bottle cap with the opening facing upward, cooperating with the subsequent marking operation. In the above operation, to prevent the second receiving plate 14 from rotating excessively and not being able to align with the discharge belt, a second clamping post 18 is also provided at the corresponding position on the hinge seat 2 to block the continuous rotation of the second receiving plate 14 and limit the lowest position of the second receiving plate 14, cooperating with the sliding of the bottle cap.

[0028] After the bottle cap with the opening facing upward after flipping slides to the right onto the discharge belt, the flipping rod 3 rotates in reverse to drive the first receiving plate 5 to rotate back to its original position. At this time, the second flipping plate can also rotate back to its original position under the action of the restoring force of the torsion spring and the connecting rod group 16. During this period, the second receiving plate 14 flips until it contacts the first clamping post 17 and stops rotating. The first receiving plate 5 then continues to rotate back to its original position, waiting for the conveyance of the next batch of bottle caps. The connecting rod group 16 can fold under a certain applied force to prevent the device from being overloaded.

[0029] Continuing, a cylinder 7 is also provided at the front side of the top of the workbench 1. The telescopic end of the cylinder 7 is provided with a push plate 9 through a connecting piece 8. An installation groove 10 is provided on the left side of the push plate 9, and a rack 11 is arranged in the installation groove 10. Further, when a gear 12 is provided at a position on the turning rod 3 above the rack 11, the continuous telescoping of the cylinder 7 can drive the rack 11 to slide left and right through the connecting piece 8, the push plate 9, and the installation groove 10. The number of teeth of the rack 11 is 1 / 2 of that of the gear 12. In this way, the turning rod 3 can be driven to swing left and right by 180° through the meshing of the rack 11 and the gear 12. To cooperate with the precise meshing of the rack 11 and the gear 12, a slide rail 19 is also provided at the position below the rack 11 on the top of the workbench 1, and a slider 20 is slidably arranged on the slide rail 19 and connected to the bottom of the rack 11. In this way, the rack 11 can move horizontally left and right under the action of the slider 20, preventing the rack 11 from disengaging from the meshing with the gear 12 and affecting the operation of the device.
