Description

Technical Field

[0001] The utility model relates to the technical field of packaging bottle processing, and particularly relates to an inner seal paper pressing device for the cap of a plastic packaging bottle. Background Technique

[0002] For currently used packaging bottles, such as plastic or glass bottles for containing beverages or cleaning agents, an inner seal paper is pressed on the inner side of the cap. The functions of the inner seal paper are as follows: when the inner seal paper is pressed tightly at the bottom of the cap, a raised edge will be formed along the inner wall of the cap at the edge of the inner seal paper. This raised edge can form a sealing effect on the bottle mouth when the cap of the packaging is tightened. Second, the inner seal paper is pressed tightly at the bottom of the cap, so that there is a buffer between the cap and the bottle mouth, which can well protect the cap from being easily broken and protect the bottle mouth.

[0003] The prior art discloses an inner seal paper pressing device for the cap of a packaging bottle with the application number CN202322280779.4, which includes a bottom frame. The first roller and the second roller are rotatably installed on the left and right sides of the upper end of the bottom frame. A conveyor belt is connected between the first roller and the second roller. Side plates are fixedly installed on the front and rear sides of the second roller. A Y-shaped baffle is fixedly installed between the two side plates and the right side of the top of the bottom frame, and the Y-shaped baffle is located above the conveyor belt. A third support is fixedly installed above the bottom frame and is located on the front and rear sides of the conveyor belt. This utility model relates to the technical field of cap production. This inner seal paper pressing device for the cap of a packaging bottle uses the Y-shaped baffle to enable the caps to be transported on the conveyor belt in an orderly manner, so that the caps can travel along the correct direction to the lower part of the pressing device. At the same time, the caps can be lined up to make the caps travel in sequence, realizing the automation of the device and saving manpower. However, when this device is used, the conveyor belt is used to transport the caps, and the conveyor belt is closed when it is transported to the appropriate position, and then the capping mechanism presses downwards. However, when it is transported to the position, the caps may shift due to inertia, so that the caps are not directly below the capping device, resulting in inaccurate capping and poor practicability. Content of the Utility Model

[0004] Based on this, the purpose of the present utility model is to provide an inner seal paper pressing device for the cap of a plastic packaging bottle to solve the technical problems in the above background technique.

[0005] To achieve the above object, the utility model provides the following technical solution: an inner seal paper pressing device for the cap of a plastic packaging bottle, a packaging workbench. A first mounting frame and a second mounting frame are respectively arranged on the top of the workbench. A rotating shaft is mounted on the first mounting frame, and a rotating cylinder is arranged on the second mounting frame. One end of the rotating shaft extends into the rotating cylinder and is provided with a ratchet wheel. A bevel gear is fixed at the other end of the rotating shaft. A gear is arranged on the outer surface of the rotating cylinder. A ratchet pawl is arranged on the inner wall of the rotating cylinder, and a spring is arranged on one side of the ratchet pawl. A support frame is arranged on one side of the top of the workbench. A hydraulic rod is mounted on the top of the support frame, and a movable frame is arranged at the output end of the hydraulic rod. A pressing block is arranged at the bottom of the movable frame through a fixed rod, and a toothed rod is fixed on one side of the bottom of the movable frame. A storage cylinder is arranged on one side of the support frame. A turntable is fixed on the middle of the top of the workbench through a rotating shaft, and a limiting port is arranged on the top of the turntable. A toothed ring is arranged on the outer surface of the turntable.

[0006] Further, a chute is formed on the inner wall of the support frame, and the movable frame is in sliding fit with the chute.

[0007] By adopting the above technical solution, under the limiting action of the chute, the movable frame will not swing or deflect forward, backward, left or right during movement.

[0008] Further, a control panel is arranged on the other side of the support frame, and the control panel is electrically connected to the hydraulic rod.

[0009] By adopting the above technical solution, the staff can control the hydraulic rod through the control panel.

[0010] Further, a blanking port and an aggregate trough are respectively arranged at the bottom of the workbench, and the aggregate trough is located directly below the blanking port.

[0011] By adopting the above technical solution, the pressed caps will fall downward from the limiting port and then fall into the aggregate trough through the blanking port.

[0012] Further, several groups of limiting ports are provided, and several groups of limiting ports are equidistantly distributed in a ring shape.

[0013] By adopting the above technical solution, the caps will be adapted in the limiting ports, and when the turntable rotates, the limiting ports will drive the caps to rotate.

[0014] Further, the bevel gear is meshed with the toothed ring.

[0015] By adopting the above technical solution, when the bevel gear rotates, the toothed ring will rotate, and then the turntable will rotate.

[0016] Further, the toothed rod is meshed with the gear.

[0017] By adopting the above technical solution, when the rack moves upward or downward, the gear will rotate.

[0018] Furthermore, there are two sets of hydraulic rods, and the two sets of hydraulic rods are symmetrically distributed with the longitudinal axis of the movable frame as the center.

[0019] By adopting the above technical solution, when the movable frame moves up and down under the action of the two sets of hydraulic rods, the force is more evenly distributed.

[0020] Furthermore, one side of the bottom of the workbench is penetrated by a notch, and the notch is located directly below the rack.

[0021] By adopting the above technical solution, under the action of the notch, when the rack moves downward, it will not touch the workbench.

[0022] In summary, the main beneficial effects of the present utility model are as follows: The present utility model can place the bottle caps with inner seal papers one by one into the storage cylinder through the storage cylinder. When the pressing block moves downward, the rack also moves downward, thereby causing the gear to rotate clockwise. The clockwise rotation of the gear causes the rotating cylinder to drive the pawl to rotate clockwise. The pawl will not drive the ratchet to rotate. When the pressing is completed, the pressing block and the rack move upward synchronously, so that the gear drives the rotating cylinder to rotate counterclockwise, and then the pawl rotates following the rotating cylinder. Since the pawl is clamped on the ratchet, the pawl drives the ratchet to rotate. After the ratchet rotates, it drives the bevel gear to rotate through the rotating shaft. The rotation of the bevel gear causes the toothed ring to rotate, and then the turntable rotates by a certain angle. In this way, the bottle cap can be positioned directly below the pressing block, and the pressed bottle cap is toggled above the discharge opening, so that the pressed bottle cap falls into the collection tank. Moreover, the limiting opening without a bottle cap will rotate to a position directly below the storage cylinder, and the bottle cap will fall from the storage cylinder into the limiting opening to wait for pressing. By this means, the coherence during the operation of the pressing device is improved, the degree of automation is high, and the pressing is more accurate. BRIEF DESCRIPTION OF THE DRAWINGS

A control panel 3 is provided on the other side of the support frame 2, and the control panel 3 is electrically connected to the hydraulic rod 4. The staff can control the hydraulic rod 4 through the control panel 3. The bottom of the movable frame 5 is provided with a pressing block 8 through a fixed rod 7, and a rack 9 is fixed on one side of the bottom of the movable frame 5. The rack 9 is meshed with the gear 18. When the rack 9 moves up or down, the gear 18 will rotate. A storage cylinder 10 is provided on one side of the support frame 2. The middle of the top of the workbench 1 is fixed with a turntable 12 through a rotating shaft 11, and a limiting port 25 is provided on the top of the turntable 12. A toothed ring 24 is provided on the outer surface of the turntable 12. The bevel gear 20 is meshed with the toothed ring 24. When the bevel gear 20 rotates, the toothed ring 24 will rotate, and then the turntable 12 will rotate.

[0031] Refer to Figure 1, in the above embodiment, a blanking port 13 and an aggregate chute 14 are respectively provided at the bottom of the workbench 1, and the aggregate chute 14 is located directly below the blanking port 13. The tightly pressed bottle caps will fall downward from the limiting port 25 and then fall into the aggregate chute 14 through the blanking port 13.

[0032] Refer to Figure 1 4, in the above embodiment, several groups of the limiting ports 25 are provided, and several groups of the limiting ports 25 are equidistantly distributed in an annular shape. The bottle caps will be fitted in the limiting ports 25, and when the turntable 12 rotates, the limiting ports 25 will drive the bottle caps to rotate.

[0033] Refer to Figure 1 , in the above embodiment, two sets of hydraulic rods 4 are provided, and the two sets of hydraulic rods 4 are symmetrically distributed with the longitudinal axis of the movable frame 5 as the center. The two sets of hydraulic rods 4 make the force more uniform when the movable frame 5 moves up and down.

[0036] The implementation principle of the present utility model is as follows: First, the staff place the bottle caps with inner sealing papers one by one into the storage cylinder 10, and then place a bottle cap with an inner sealing paper into the limiting port 25 directly below the pressing block 8. When the pressing block 8 moves downward, the toothed rod 9 also moves downward, thereby causing the gear 18 to rotate clockwise. The clockwise rotation of the gear 18 causes the rotating cylinder 17 to drive the pawl 22 to rotate clockwise. The pawl 22 will not drive the ratchet wheel 21 to rotate. After the pressing is completed, the pressing block 8 and the toothed rod 9 move upward synchronously, so that the gear 18 drives the rotating cylinder 17 to rotate counterclockwise, and then the pawl 22 rotates following the rotating cylinder 17. Since the pawl 22 is clamped on the ratchet wheel 21, the pawl 22 drives the ratchet wheel 21 to rotate. After the ratchet wheel 21 rotates, it drives the bevel gear 20 to rotate through the rotating shaft 19. The rotation of the bevel gear 20 causes the toothed ring 24 to rotate, and then the turntable 12 rotates by a certain angle. In this way, the bottle cap can be positioned directly below the pressing block 8, and the pressed bottle cap is dialed above the blanking port 13, so that the pressed bottle cap falls into the collection tank. Moreover, the limiting port 25 without a bottle cap will rotate to a position directly below the storage cylinder 10, and the bottle cap will fall from the storage cylinder 10 into the limiting port 25 waiting to be pressed.
