Description

Technical Field

[0001] This utility model relates to the field of bottle cap printing technology, and in particular to a bottle cap side printing unit. Background Technology

[0002] When printing on the sides of bottle caps, screen printing is mostly used. However, for a small number of specially made bottle caps, in order to save costs, the screen pattern is often changed and then the printing is done manually.

[0003] These manually operated screen printing machines for bottle caps have a rotating wheel mechanism under the screen to hold the bottle caps. When placing the bottle caps, the screen needs to be moved aside, and the bottle caps need to be placed side up before the screen printing is completed. This makes it difficult to quickly place the bottle caps and guide them under the screen pattern, resulting in low efficiency. Utility Model Content

[0004] This invention provides a bottle cap side printing unit that, before screen printing, quickly places the bottle cap side upwards and guides it under the screen pattern, ensuring the bottle cap side adheres to the screen pattern, thereby solving the problems mentioned in the background art.

[0005] It is inefficient because it cannot quickly place bottle caps and guide them under the screen pattern.

[0006] To achieve the above objectives, this utility model provides a bottle cap side printing unit, including a printing body and a sliding screen mechanism disposed on the printing body. The sliding screen mechanism has a feeding component for rapid material addition on one side, and also includes a placement and transport mechanism. The placement and transport mechanism includes a circulating transport belt disposed at the lower end of the sliding screen mechanism and bottle cap holders disposed on the circulating transport belt. Multiple bottle cap holders are disposed on the circulating transport belt, and the movement path of the bottle cap holders is located directly below the screen pattern of the sliding screen mechanism. The circulating transport belt includes a guiding and bonding component located directly below the screen pattern of the sliding screen mechanism. The guiding and bonding component acts on the circulating transport belt and the bottle cap holders, forming an inclined lifting effect on the bottle cap holders, thereby allowing the bottle cap holders to carry the bottle caps obliquely upwards and bond with the screen pattern of the sliding screen mechanism.

[0007] By using a circulating transport belt and a bottle cap holder, the bottle cap is placed on the holder and transported directly below the screen pattern of the sliding screen printing mechanism. Guided by the guide bonding component, the bottle cap holder and the bottle cap move diagonally upwards and adhere to the screen pattern of the sliding screen printing mechanism during the movement, thus quickly placing the bottle cap and guiding it under the screen pattern. The screen printing is then completed by the printing body and the sliding screen printing mechanism, improving efficiency.

[0008] As a further embodiment of this utility model, the circulating transport belt also includes a concave base, a stepper motor, and a limiting belt. The concave base is located directly below the sliding wire mesh mechanism, the stepper motor is located outside the side wall of the concave base, and the limiting belt includes rotating wheels. Multiple rotating wheels are provided in the concave part of the concave base, and one of the rotating wheels is connected to the stepper motor.

[0009] As a further embodiment of this utility model, the limiting wheel belt also includes an outer ring belt, which is arranged around the concave part of the wheel body of the multiple rotating wheels, and the rotation path of the outer ring belt is located directly below the sliding wire mesh mechanism. The bottle cap holder is arranged on the outer ring belt.

[0010] Among them, the multiple rotating wheels increase in height and then decrease in height along the length of the concave base, and the middle rotating wheel is located directly below the center of the sliding wire mesh mechanism. The guide fitting component is located on both sides of the middle rotating wheel, guiding the middle of the outer ring belt to approach the sliding wire mesh mechanism.

[0011] Based on this, the guiding bonding component includes two parallel rotating shafts, which are distributed on both sides of the central rotating wheel. The outer ring belt wraps around the surface of the rotating shafts and is parallel to the central pattern of the sliding wire mesh mechanism under the support of the two rotating shafts and the central rotating wheel.

[0012] As a further embodiment of this utility model, the bottle cap mounting component includes an L-shaped base block that fits against the surface of the outer ring belt and a rotating wheel mounting bracket disposed on the L-shaped base block. The edges of the L-shaped base block and the rotating wheel mounting bracket are provided with limiting edge blocks for restricting the position of the bottle cap.

[0013] As a further embodiment of this utility model, the rotating wheel mounting bracket includes two parallel base wheels and a soft limiting pad disposed on the base wheels. The two base wheels are disposed on an L-shaped base block, and the soft limiting pad is disposed on the shaft of the base wheels, and the soft limiting pad forms a vertical space for placing the bottle cap between the two base wheels.

[0014] Based on this, the limiting edge block is an arc-shaped block, and the limiting edge block is set on the edge of the L-shaped base block. The concave arc surface of the limiting edge block faces the vertical space formed by the soft limiting pad between the two base wheels.

[0015] As a further embodiment of this utility model, a printing squeegee is provided on one side of the printing body, and the sliding screen mechanism includes a horizontal screen and a control component for controlling the horizontal sliding of the horizontal screen. A printing pattern is provided in the center of the horizontal screen, and the printing squeegee is located directly above the horizontal screen. The movement paths of the outer ring belt and the bottle cap holder are located directly below the printing pattern of the horizontal screen.

[0016] This technical solution, with its height-gradiently distributed rotating wheels and outer ring belt, along with the auxiliary lifting of the guiding bonding components, allows multiple bottle cap holders on the outer ring belt to pass sequentially below the sliding screen mechanism. The stepper motor controls their stopping, ensuring that the bottle caps on the holders can be precisely stopped below the sliding screen mechanism for printing. Multiple bottle cap holders can simultaneously perform bottle cap loading, unloading, and printing, enabling continuous transport of bottle caps and shortening the operation time for placing bottle caps.

[0017] Compared with the prior art, the present invention provides a bottle cap side printing unit, which has the following beneficial effects:

[0018] This invention uses a stepper motor to drive a rotating wheel to rotate and move an outer belt. By vertically placing the bottle cap on the bottle cap holder and moving it with the outer belt, and through the tilting guidance of the rotating wheel and the tilting and lifting of the bonding component, the bottle cap is quickly moved to the bottom of the sliding screen mechanism. This ensures that the bottle cap accurately fits the screen pattern during transportation, guaranteeing consistent printing position and quickly completing screen printing. This enables continuous transportation and printing of bottle caps, improving efficiency.

[0019] In addition, the combination of the limiting edge block and soft limiting pad of the bottle cap holder stabilizes and fixes the vertical posture of the bottle cap, avoiding printing offset or misalignment. The multi-station bottle cap holder design can perform loading and unloading and printing simultaneously, shortening the single operation cycle. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Reference Figure 1 , Figure 3 and Figure 6 To quickly position the bottle cap side-up and guide it under the screen pattern before screen printing, ensuring the bottle cap side adheres to the pattern, this utility model discloses a bottle cap side printing unit. This unit includes a printing body 1 and a sliding screen mechanism 2 mounted on the printing body 1. A feeding component 5 for rapid material addition is located on one side of the sliding screen mechanism 2. The feeding component 5 is a device for adding printing material to the sliding screen mechanism 2 (details omitted here). The unit also includes a placement and transport mechanism, which includes a circulation system located at the lower end of the sliding screen mechanism 2. The conveyor belt 3 and the bottle cap holder 4 are provided on the circulating conveyor belt 3. Multiple bottle cap holders 4 are provided on the circulating conveyor belt 3, and the movement path of the bottle cap holder 4 is located directly below the screen pattern of the sliding screen mechanism 2. The circulating conveyor belt 3 includes a guide bonding component 31 located directly below the screen pattern of the sliding screen mechanism 2. The guide bonding component 31 acts on the circulating conveyor belt 3 and the bottle cap holder 4 to tilt and lift the bottle cap holder 4, so that the bottle cap holder 4 carries the bottle cap and moves obliquely upward to bond with the screen pattern of the sliding screen mechanism 2.

[0029] like Figure 3 As shown, the circulating transport belt 3 also includes a concave base 32, a stepper motor 33, and a limiting belt 34. The concave base 32 is located directly below the sliding wire mesh mechanism 2. The stepper motor 33 is located outside the side wall of the concave base 32. The limiting belt 34 includes a rotating wheel 341. Multiple rotating wheels 341 are provided in the concave part of the concave base 32, and one of the rotating wheels 341 is connected to the stepper motor 33.

[0030] like Figure 5As shown, the limiting wheel belt 34 also includes an outer ring belt 342, which is arranged around the concave part of the wheel body of the multiple rotating wheels 341, and the rotation path of the outer ring belt 342 is located directly below the sliding wire mesh mechanism 2. The bottle cap holder 4 is arranged on the outer ring belt 342.

[0031] Among them, multiple rotating wheels 341 increase in height and then decrease in height along the length of the concave base 32, with the middle rotating wheel 341 located directly below the center of the sliding wire mesh mechanism 2. The guide fitting component 31 is located on both sides of the middle rotating wheel 341, guiding the middle of the outer ring belt 342 towards the sliding wire mesh mechanism 2. Figure 4 and Figure 5 As shown, the bottle cap holder 4 is mounted on the outer ring belt 342. When the outer ring belt 342 rotates with the rotating wheel 341, the bottle cap holder 4 can gradually approach the sliding wire mesh mechanism 2. Under the control of the stepper motor 33, the bottle cap holder 4 stops when it reaches directly below the sliding wire mesh mechanism 2.

[0032] like Figure 5 As shown, the guide bonding component 31 includes two parallel rotating shafts, which are distributed on both sides of the central rotating wheel 341. The outer ring belt 342 wraps around the surface of the rotating shafts, and the outer ring belt 342 is parallel to the central pattern of the sliding screen printing mechanism 2 under the support of the two rotating shafts and the central rotating wheel 341. This allows the bottle cap holder 4 and the bottle cap to move directly below the central pattern of the sliding screen printing mechanism 2 with the outer ring belt 342, and under the support of the two rotating shafts and the central rotating wheel 341, the bottle cap holder 4 and the bottle cap will also be parallel to the central pattern of the sliding screen printing mechanism 2. At this time, the bottle cap will be attached to the screen printing pattern, which can better facilitate screen printing.

[0033] like Figure 2 As shown, a printing squeegee 11 is provided on one side of the printing body 1. The printing squeegee 11 can be controlled by the printing body 1 to move vertically. The sliding screen mechanism 2 includes a horizontal screen 21 and a control component for controlling the horizontal sliding of the horizontal screen 21. A printing pattern is provided in the center of the horizontal screen 21, and the printing squeegee 11 is located directly above the horizontal screen 21. The movement paths of the outer ring belt 342 and the bottle cap holder 4 are located directly below the printing pattern of the horizontal screen 21. The bottle cap can be transported to the bottom of the printing pattern and attached to it in a vertical position on its side by the bottle cap holder 4 and the outer ring belt 342. At this time, the printing squeegee 11 can be controlled to attach to the top of the horizontal screen 21. Then, the horizontal screen 21 is controlled to slide horizontally by the control component. At this time, the horizontal screen 21 will be pressing the vertical side of the bottle cap, and the bottle cap will rotate on the base wheel 421, so that the printing squeegee 11 can print the pigment on the side of the bottle cap through the printing pattern, thus completing the side printing of the bottle cap.

[0034] It should be clarified that one end of the concave base 32 extends beyond the edge of the sliding screen mechanism 2, providing space for placing bottle caps. Multiple bottle cap holders 4 are on the outer ring belt 342. As the outer ring belt 342 moves, bottle caps can be placed onto the bottle cap holders 4 in sequence. Under the control of the stepper motor 33, the bottle caps of the multiple bottle cap holders 4 pass under the sliding screen mechanism 2 in sequence to complete the screen printing, thereby improving efficiency.

[0035] like Figure 3 and Figure 6 As shown, the bottle cap mounting component 4 includes an L-shaped base block 41 that fits the surface of the outer ring belt 342 and a rotating wheel mounting bracket 42 disposed on the L-shaped base block 41. Limiting edge blocks 43 for limiting the position of the bottle cap are provided at the edges of the L-shaped base block 41 and the rotating wheel mounting bracket 42.

[0036] The rotating mounting bracket 42 includes two parallel base wheels 421 and a soft limiting pad 422 disposed on the base wheels 421. The two base wheels 421 are disposed on an L-shaped base block 41, and the soft limiting pad 422 is disposed on the shaft of the base wheels 421. The soft limiting pad 422 forms a vertical space for placing the bottle cap between the two base wheels 421. When the bottle cap is restricted by the soft limiting pad 422, it is placed vertically against the two base wheels 421. When the bottle cap is against the screen, the horizontal displacement of the screen can drive the bottle cap to rotate between the two base wheels 421, thereby facilitating the screen to print the pattern on the side of the bottle cap.

[0037] like Figure 6 As shown, the limiting block 43 is an arc-shaped block, and the limiting block 43 is set on the edge of the L-shaped base block 41. The concave arc surface of the limiting block 43 faces the vertical space formed by the soft limiting pad 422 between the two base wheels 421. This means that after the bottle cap is vertically placed in the vertical space between the soft limiting pads 422, one side of the bottle cap will fit against the concave arc surface of the limiting block 43, thereby further restricting the rotation of the bottle cap.

[0038] Working principle: First, printing material is added to the sliding screen mechanism 2 via the feeding component 5. Then, the printing squeegee 11 is controlled to adhere to the surface of the horizontal screen 21. At this time, on one side of the concave base 32, the bottle cap is placed vertically between the two base wheels 421 with the side facing upwards. The soft limiting pad 422 adheres to both sides of the bottle cap to form a constraint, thus placing the bottle cap vertically upwards on the bottle cap holder 4. The stepper motor 33 is started to drive the rotating wheel 341 to rotate. Under the guidance of the guiding bonding component 31 and multiple rotating wheels 341, the entire bottle cap holder 4 and the bottle cap will tilt upwards and gradually approach the sliding screen mechanism 2. Under the control of the stepper motor 33, the bottle cap holder 4 and the bottle cap stop when they reach directly below the sliding screen mechanism 2. At this time, the bottle cap on the bottle cap holder 4 will adhere to the screen pattern in the center of the horizontal screen 21. Since the printing squeegee 11 is attached to the surface of the horizontal screen 21, the horizontal screen 21 can be controlled to slide horizontally by the control components. At this time, the horizontal screen 21 will be pressed against the vertical side of the bottle cap, and the printing squeegee 11 can print the printing material through the screen pattern onto the vertical side of the bottle cap. At the same time, since the horizontal screen 21 slides against the bottle cap, it can drive the bottle cap to rotate on the base wheel 421, so that the printing squeegee 11 can print the pigment through the printing pattern completely on the curved side of the bottle cap. After the side printing of the bottle cap is completed, the stepper motor 33 continues to work, driving the rotating wheel 341 and the outer ring belt 342 to continue to move. At this time, the bottle cap holder 4 and the bottle cap will tilt downward and gradually move away from the bottom of the sliding screen mechanism 2, and finally move away from the bottom of the sliding screen mechanism 2 from the other side of the concave base 32, and the bottle cap can be removed.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
