Description

Technical Field

[0001] This utility model belongs to the field of bottle cap processing mold technology, specifically a rapid processing mold for round plastic bottle caps. Background Technology

[0002] Round plastic bottle caps are sealing components widely used in the packaging of beverages, food, cosmetics, and daily necessities. They are made of plastic and are characterized by being lightweight, low-cost, easy to process and mold, and having excellent sealing performance.

[0003] When compressing round plastic bottle caps, heated plastic preforms are placed into a mold and shaped by the pressure of the mold. However, because the bottle caps have internal threads that fit into the threads inside the mold, they cannot fall off after the mold is separated. The bottle caps need to be rotated one by one to remove them, which affects the production efficiency of bottle caps. Therefore, this process needs to be improved. Utility Model Content

[0004] The purpose of this invention is to address the above problems by providing a rapid processing mold for round plastic bottle caps, which has the advantage of improving processing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rapid processing mold for circular plastic bottle caps, comprising a worktable, a top plate fixedly installed on the rear side of the top of the worktable, a servo motor fixedly installed on the top of the top plate, a circular shaft fixedly connected to the other end of the output shaft of the servo motor, the bottom end of the circular shaft penetrating the top plate and extending to the outside of the top plate and movably sleeved with the inner wall of the top plate, a disc fixedly connected to the bottom of the circular shaft, an upper mold fixedly connected to the bottom of the disc, two crossbars fixedly installed on the right side of the top plate, a slider movably sleeved on the right side of the outer surface of each of the two crossbars, a moving plate fixedly connected to the bottom of the slider, a friction plate fixedly connected to the left side of the moving plate, a drive motor fixedly installed on the right side of the top of the top plate, a rotating shaft fixedly connected to the other end of the output shaft of the drive motor, a rotating rod fixedly sleeved on the outer surface of the rotating shaft, a hinge rod hinged to the right end of the rotating rod, and the right end of the hinge rod hinged to the top of the moving plate.

[0006] As a preferred embodiment of this utility model, a pneumatic cylinder is fixedly installed at the bottom of the inner surface of the workbench. The top of the pneumatic cylinder penetrates the workbench and extends to the outside of the workbench and is movably sleeved with the inner wall of the workbench. A lower mold is fixedly connected to the top of the pneumatic cylinder.

[0007] As a preferred embodiment of this utility model, limit blocks are fixedly installed on both the left and right sides of the back of the lower mold. A vertical rod is movably sleeved inside the limit block. The top of the vertical rod is fixedly connected to the inner surface of the top plate, and the bottom of the vertical rod is fixedly connected to the top of the worktable.

[0008] As a preferred embodiment of this utility model, a collection frame is fixedly connected to the bottom of the movable plate, and an inclined block is fixedly connected to the left side inside the collection frame.

[0009] As a preferred embodiment of this utility model, a base plate located at the bottom of the inclined block is movably installed inside the collection frame. The top of the base plate is movably connected to the bottom of the inclined block. Connecting frames located outside the collection frame are fixedly installed at both the front and rear ends of the base plate. The outer surface of the connecting frames is movably connected to the outer surface of the collection frame.

[0010] As a preferred embodiment of this invention, a spring is fixedly installed on the right side of the collection frame, and the right end of the spring is fixedly connected to the outer surface of the connecting frame.

[0011] As a preferred embodiment of this utility model, a fixing plate is fixedly installed on the top right side of the workbench, a stop bar is fixedly installed on the right side of the top of the fixing plate, the left side of the stop bar is movably connected to the right side of the connecting frame, and a collection box is movably installed on the top of the fixing plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a servo motor, a moving plate, a friction plate, and a drive motor, allows the operator to start the servo motor after the compression molding is completed, causing the circular shaft to drive the disc to rotate. Then, the drive motor is started, causing the rotating shaft to drive the rotating rod to rotate, thereby enabling the hinge rod to drive the moving plate to move to the left. At this time, the friction plate will contact the bottle cap, and as the disc rotates, the upper mold will drive the bottle cap to rotate along the outer surface of the friction plate, thereby enabling the bottle cap to quickly detach from the surface of the upper mold and improving the processing efficiency of bottle cap production.

[0014] 2. This utility model, by setting up a collection frame, a base plate, a connecting frame, and a stop bar, allows the spring to push the connecting frame to the right under the restoring force of the spring plate when the moving plate moves to the left. This causes the connecting frame to move the base plate to the right, thus moving the base plate to the right side of the inclined block and sealing the bottom of the collection frame. At this time, the detached bottle caps will fall and stay inside the collection frame. As the collection frame resets, the stop bar will press against the connecting frame, causing the base plate to gradually move below the inclined block, thus causing the bottle caps to fall into the collection box, achieving the effect of automatic collection of bottle caps.

[0021] 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.

[0022] like Figures 1 to 5 As shown, this utility model provides a rapid processing mold for round plastic bottle caps, including a workbench 1. A top plate 2 is fixedly installed on the rear side of the top of the workbench 1. A servo motor 3 is fixedly installed on the top of the top plate 2. The other end of the output shaft of the servo motor 3 is fixedly connected to a circular shaft 4. The bottom end of the circular shaft 4 passes through the top plate 2 and extends to the outside of the top plate 2 and is movably sleeved with the inner wall of the top plate 2. A disc 5 is fixedly connected to the bottom of the circular shaft 4. An upper mold 6 is fixedly connected to the bottom of the disc 5. A horizontal... There are two rods 7 and two crossbars 7. A slider 8 is movably sleeved on the right side of the outer surface of each crossbar 7. A movable plate 9 is fixedly connected to the bottom of the slider 8. A friction plate 10 is fixedly connected to the left side of the movable plate 9. A drive motor 11 is fixedly installed on the right side of the top of the top plate 2. A rotating shaft 12 is fixedly connected to the other end of the output shaft of the drive motor 11. A rotating rod 13 is fixedly sleeved on the outer surface of the rotating shaft 12. A hinge rod 14 is hinged to the right end of the rotating rod 13. The right end of the hinge rod 14 is hinged to the top of the movable plate 9.

[0023] After the compression molding is completed, the operator can start the servo motor 3 to make the circular shaft 4 drive the disc 5 to rotate, which in turn makes the upper mold 6 drive the bottle cap to rotate around the circular shaft 4. At this time, the drive motor 11 is started, which makes the rotating shaft 12 drive the rotating rod 13 to rotate, so that the hinge rod 14 can pull the moving plate 9 to move to the left under the guidance of the crossbar 7, so that the friction plate 10 contacts the bottle cap on the outer surface of the upper mold 6, so that the bottle cap can roll along the left surface of the friction plate 10 and thus detach from the outer surface of the upper mold 6.

[0024] Among them, a pneumatic cylinder 15 is fixedly installed at the bottom of the inner surface of the workbench 1. The top of the pneumatic cylinder 15 passes through the workbench 1 and extends to the outside of the workbench 1 and is movably sleeved with the inner wall of the workbench 1. The top of the pneumatic cylinder 15 is fixedly connected to the lower mold 16.

[0025] As a technical optimization of this utility model, the operator can start the pneumatic cylinder 15, which will cause the lower mold 16 to rise, thereby pressing the plastic bottle cap.

[0026] Among them, limit blocks 17 are fixedly installed on both the left and right sides of the back of the lower mold 16. A vertical rod 18 is movably sleeved inside the limit block 17. The top of the vertical rod 18 is fixedly connected to the inner surface of the top plate 2, and the bottom of the vertical rod 18 is fixedly connected to the top of the worktable 1.

[0027] As a technical optimization of this utility model, when the lower mold 16 rises, it will drive the limiting block 17 to rise along the outer surface of the vertical rod 18, thereby making the lower mold 16 rise and fall more stably.

[0028] The bottom of the movable plate 9 is fixedly connected to a collection box 19, and the left side inside the collection box 19 is fixedly connected to a slant block 20.

[0029] As a technical optimization of this utility model, the outer surface of the inclined block 20 is inclined from left to right and from top to bottom, so that the fallen bottle cap can continue to slide to the right through the inclined surface of the inclined block 20.

[0030] The bottom plate 21 located at the bottom of the inclined block 20 is movably installed inside the collection box 19. The top of the bottom plate 21 is movably connected to the bottom of the inclined block 20. Both the front and rear ends of the bottom plate 21 are fixedly installed with connecting frames 22 located outside the collection box 19. The outer surface of the connecting frame 22 is movably connected to the outer surface of the collection box 19.

[0031] As a technical optimization of this utility model, when the connecting frame 22 moves to the right, it will drive the bottom plate 21 to move to the right inside the collecting frame 19, so that the collecting frame 19 moves to the right side of the inclined block 20, thereby sealing the bottom of the collecting frame 19 and allowing the bottle cap to stay inside the collecting frame 19.

[0032] A spring 23 is fixedly installed on the right side of the collection frame 19, and the right end of the spring 23 is fixedly connected to the outer surface of the connecting frame 22.

[0033] As a technical optimization of this utility model, the spring 23 is in a compressed state. When the moving plate 9 moves to the left, the spring 23 will gradually push the connecting frame 22 to the right under the elastic recovery action, so that the base plate 21 can move to the right side of the inclined block 20.

[0034] Among them, a fixing plate 24 is fixedly installed on the top right side of the workbench 1, a stop bar 25 is fixedly installed on the right side of the top of the fixing plate 24, the left side of the stop bar 25 is movably connected to the right side of the connecting frame 22, and a collection box 26 is movably installed on the top of the fixing plate 24.

[0035] As a technical optimization of this utility model, due to the design of the stop bar 25, when the moving plate 9 moves to the rightmost side, the stop bar 25 will abut against the connecting frame 22, thereby causing the connecting frame 22 to drive the base plate 21 to move to the left, so that the bottle cap inside the collecting frame 19 can fall into the collecting box 26.

[0036] Working principle and usage process of this utility model:

[0037] The operator places the heated plastic preform into the lower mold 16, then activates the pneumatic cylinder 15, causing the lower mold 16 to rise, thus inserting the upper mold 6 into the lower mold 16 to complete the compression molding of the round plastic bottle cap. After the round plastic bottle cap cools, the operator activates the pneumatic cylinder 15 again, causing the lower mold 16 to reset. At this time, the operator activates the servo motor 3, causing the circular shaft 4 to drive the disc 5 to rotate, thus causing the upper mold 6 to rotate around the circular shaft 4. Then, the operator activates the drive motor 11, causing the rotating shaft 12 to drive the rotating rod 13 to rotate, thus allowing the hinge rod 14 to pull the moving plate 9 to move to the left under the guidance of the crossbar 7, so that the friction plate 10 contacts the bottle cap. At this time, as the disc 5 rotates, the bottle cap will roll along the left surface of the friction plate 10, thus quickly detaching from the outer surface of the upper mold 6, improving the processing efficiency of bottle cap production.

[0038] When the moving plate 9 moves to the left, it will drive the collection frame 19 to move to the left. This will cause the spring 23 to gradually push the connecting frame 22 to the right under the elastic recovery action. The connecting frame 22 will then move the bottom plate 21 to the right side of the inclined block 20, thereby sealing the bottom of the collection frame 19. After the bottle cap falls off, it will fall into the inside of the collection frame 19. When the operator restarts the drive motor 11, the rotating shaft 12 will reverse and the moving plate 9 will gradually return to its original position. At this time, the connecting frame 22 will contact the stop bar 25, and the stop bar 25 will press against the connecting frame 22. This will cause the bottom plate 21 to gradually move to the bottom of the inclined block 20, so that the bottle cap inside the collection frame 19 will fall into the inside of the collection box 26, completing the automatic collection of the bottle cap.
