Description

Technical Field

[0001] The invention belongs to the technical field of plastic product processing equipment and relates to a quick-install integrated platform on a capping machine. Background Art

[0002] The capping machine is a device for pressing gaskets into plastic bottle caps. The basic action of completing the function online is: the actuator end of the cylinder is a reversible swing arm structure, which absorbs the gaskets one by one, then flips to the bottle cap on the conveyor belt, presses down, and presses the gasket into the inner wall of the bottle cap. Due to the various specifications of plastic packaging containers, a capping machine corresponds to many product models. When pressing gaskets into caps of different models (different sizes, gasket materials, etc.), it is necessary to replace the corresponding gasket feeding unit and cylinder actuator end. In addition, it is also necessary to adjust the cylinder position, gasket feeding position and cylinder stroke, etc. Therefore, in the prior art, each unit on the capping machine is a detachable part, and each unit needs to be re-disassembled and adjusted for different products. It takes two workers about half a day to complete the replacement and debugging to complete a capping product replacement, which seriously affects the processing efficiency. Especially when the number of a single product is small, frequent replacement greatly increases the cost of the product. Summary of the invention

[0003] The purpose of the present invention is to provide a quick-install integrated platform on a capping machine in view of the above-mentioned problems existing in the prior art. The technical problem to be solved by the present invention is how to improve the operating efficiency of the capping machine.

[0004] The objective of the present invention can be achieved through the following technical solutions: a quick-install integrated platform on a capping machine, the capping machine comprising a frame and a conveyor belt arranged on the frame, characterized in that the frame is provided with a mother seat located above the conveyor belt and a plurality of quick-install platforms cooperating with the mother seat, the cylinder required for pressing a single type of gasket into the corresponding cover body and the gasket guide frame are arranged on the same quick-install platform, the quick-install platform and the mother seat are detachably connected, and the corresponding quick-install platform is selected to be installed on the mother seat to complete the capping operation of the corresponding type of gasket.

[0005] One of the improvements of this solution compared with the prior art is that in the prior art, each unit of the capping mechanism located above the conveyor belt on the line is a detachable part, and each replacement requires the replacement of the corresponding cylinder and gasket guide frame, and debugging and adjustment thereof. The disassembly and assembly operation takes a long time, and the size of each component itself is also small, making the operation difficult. In this solution, the devices required for the capping operation of different gaskets are integrated into the same quick-release platform, and the quick-release platforms are made into the same specifications, so that each quick-release platform can be adapted to the motherboard and can be disassembled and assembled. In this way, when dealing with gaskets of different models, the corresponding quick-release platform can be directly replaced without the need to disassemble and assemble the small components thereon, so that matching components are integrated on one platform, and the capping operation of the corresponding gasket can be completed by replacing the corresponding platform. The integrated approach reduces the intensity of the operation, and after the installation is completed, it is only necessary to connect the pipeline circuit through a quick connector to start the operation.

[0006] Furthermore, the mother seat is a frame plate with a hollow middle portion, the quick-release platform includes two symmetrically arranged pressure cover units and a locking assembly for positioning the two pressure cover units on the mother seat, the pressure cover unit includes a mounting plate and at least two swinging members arranged on the outside of the mounting plate, the swinging members include a swing arm hinged on the mounting plate and a plug rod connected to the outer end of the swing arm, and the mother seat has a socket adapted for the plug rod; the locking assembly includes a first boss located at the front end of the mother plate, a second boss located at the rear end of the mother plate, and a locking plate connected between the first boss and the second boss, a screw threadedly matched therewith is passed through the middle of the locking plate, one end of the screw is rotatably connected to the first boss via a bearing, and the other end of the screw is rotatably connected to the second boss via a bearing, and the locking plate is T-shaped, and includes an intermediate plate located between the two mounting plates and an end plate perpendicular to the intermediate plate.

[0007] Furthermore, the mounting plate is rectangular, and the other three sides of the mounting plate except the side on which the swinging member is mounted have wedge-shaped guide bars, the second boss has a positioning groove adapted to the wedge-shaped guide bar on the corresponding side of the mounting plate, the middle plate is wedge-shaped, and the two side surfaces of the middle plate are respectively adapted to the wedge-shaped guide bars on the corresponding sides of the two mounting plates; the inner end surface of the end plate is adapted to the wedge-shaped guide bar on the corresponding side of the mounting plate.

[0008] Furthermore, a plurality of guide pillars are fixedly arranged on the end plate, and the guide pillars are slidably connected to the first boss.

[0009] Furthermore, one end of the screw rod close to the second boss is connected to a crank handle.

[0010] Another core difference between the present solution and the prior art is that the existing quick disassembly and assembly method cannot complete the high-precision installation of a "panel" by only using one locking piece. Generally speaking, a panel requires at least four latch structures to be well positioned, but it can only achieve the determination of the plane position of the panel. There are still positioning defects in the longitudinal direction parallel to the axis of the latch. In the present solution, the one-time positioning of the two mounting plates can be achieved by rotating the screw, which includes not only the longitudinal positioning but also the determination of the horizontal position.

[0011] Specifically, each mounting plate is provided with a set of gland accessories, and the outer edge of the mounting plate has at least two swing arms, one end of the swing arm is hinged on the mounting plate, and the other end of the swing arm has a plug rod, which is adapted to the socket on the motherboard. When the plug rod is inserted into the corresponding socket, each swing arm forms a parallel connecting rod structure. The mounting plate has a certain range of movable space due to the swing of the swing arm. The existence of this movable space is not only conducive to the disassembly and assembly of the mounting plate, but also because the parallel connecting rod determines the movable trajectory of the mounting plate in the plane, thereby realizing preliminary positioning. However, this positioning is based on the premise that it can be quickly Under the premise of completing the initial positioning of the two mounting plates quickly, the screw is rotated to make the locking plate push the two mounting plates with a large distance to each other, and tend to approach the second boss during the approaching process until the mounting plate is pressed by the second boss and the end plate. During and after the pressing process, the wedge-shaped guide bar and the position in contact with it realize the guidance and longitudinal locking, and determine the longitudinal position of the mounting plate. In this way, the three-dimensional position of the mounting plate is determined. The operation is very simple, and the positioning accuracy and positioning reliability are extremely high. The disassembly and assembly space is also increased due to the existence of the swing arm, which improves the ease of operation. A locking nut can be set on the second boss to press the screw after it is rotated to the specified position to prevent the screw from loosening. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figures 1 to 5 As shown, the capping machine includes a frame 1 and a conveyor belt 2 arranged on the frame 1, and the frame 1 is provided with a mother seat 3 located above the conveyor belt 2 and a plurality of quick-loading platforms cooperating with the mother seat 3. The cylinder required for pressing a single type of gasket into the corresponding cover body and the gasket guide frame are arranged on the same quick-loading platform, and the quick-loading platform and the mother seat 3 are detachably connected. The corresponding quick-loading platform is selected to be installed on the mother seat 3 to complete the capping operation of the corresponding type of gasket.

[0020] The mother seat 3 is a frame plate with a hollow middle part. The quick-loading platform includes two symmetrically arranged pressure cover units and a locking assembly for positioning the two pressure cover units on the mother seat 3. The pressure cover unit includes a mounting plate 4 and at least two swinging members arranged on the outside of the mounting plate 4. The swinging member includes a swing arm 15 hinged on the mounting plate 4 and a plug rod 5 connected to the outer end of the swing arm 15. The mother seat 3 has a socket 6 adapted to the plug rod 5; the locking assembly includes a first boss 7 located at the front end of the mother plate, a second boss 8 located at the rear end of the mother plate, and a locking plate connected between the first boss 7 and the second boss 8. A screw 9 threadedly matched with the screw is passed through the middle of the locking plate. One end of the screw 9 is rotatably connected to the first boss 7 through a bearing, and the other end of the screw 9 is rotatably connected to the second boss 8 through a bearing. The locking plate is T-shaped, and the locking plate includes an intermediate plate 10 located between the two mounting plates 4 and an end plate 11 perpendicular to the intermediate plate 10.

[0021] The mounting plate 4 is rectangular, and the other three sides of the mounting plate 4 except the side on which the swinging member is mounted are provided with wedge-shaped guide bars 12. The second boss 8 is provided with a positioning groove adapted to the wedge-shaped guide bars 12 on the corresponding side of the mounting plate 4. The middle plate 10 is wedge-shaped, and the two side surfaces of the middle plate 10 are respectively adapted to the wedge-shaped guide bars 12 on the corresponding sides of the two mounting plates 4; the inner end surface of the end plate 11 is adapted to the wedge-shaped guide bars 12 on the corresponding side of the mounting plate 4.

[0022] A plurality of guide posts 13 are fixedly arranged on the end plate 11, and the guide posts 13 are slidably connected to the first boss 7. A crank 14 is connected to one end of the screw rod 9 close to the second boss 8.

[0023] One of the improvements of the present scheme compared with the prior art is that in the prior art, each unit of the capping mechanism located above the online conveyor belt 2 is a detachable part, and each replacement requires the replacement of the corresponding cylinder and gasket guide frame, and debugging and adjustment thereof. The disassembly and assembly operation takes a long time, and the size of each component itself is also small, making the operation difficult. In the present scheme, the devices required for the capping operation of different gaskets are integrated into the same quick-release platform, and the quick-release platforms are made into the same specifications, so that each quick-release platform can be adapted to the motherboard and can be disassembled and assembled. In this way, when dealing with gaskets of different models, the corresponding quick-release platform can be directly replaced without the need to disassemble and assemble the small components thereon, so that matching components are integrated on one platform, and the capping operation of the corresponding gasket can be completed by replacing the corresponding platform. The integrated approach reduces the intensity of the operation, and after the installation is completed, it is only necessary to connect the pipeline circuit through a quick connector to start the operation.

[0024] Another core difference between the present solution and the prior art is that the existing quick disassembly and assembly method cannot complete the high-precision installation of a "panel" by only using one locking piece. Generally speaking, a panel requires at least four latch structures to be well positioned, but it can only achieve the determination of the plane position of the panel. There are still positioning defects in the longitudinal direction parallel to the axis of the latch. In the present solution, the one-time positioning of the two mounting plates 4 can be achieved by rotating the screw 9, which includes not only the longitudinal positioning but also the determination of the horizontal position.

[0025] Specifically, each mounting plate 4 is provided with a set of gland accessories, and the outer edge of the mounting plate 4 is provided with at least two swing arms 15, one end of the swing arm 15 is hinged on the mounting plate 4, and the other end of the swing arm 15 is provided with a plug rod 5, and the plug rod 5 is adapted to the socket 6 on the motherboard. When the plug rod 5 is inserted into the corresponding socket 6, each swing arm 15 forms a parallel connecting rod structure. The mounting plate 4 has a certain range of activity space due to the swing of the swing arm 15. The existence of the activity space is not only conducive to the disassembly and assembly of the mounting plate 4, but also because the parallel connecting rod determines the activity trajectory of the mounting plate 4 in the plane, and realizes the preliminary positioning. However, this positioning is established. Under the premise of being able to be completed quickly, after completing the preliminary positioning of the two mounting plates 4, the screw rod 9 is rotated so that the locking plate pushes the two mounting plates 4, which were originally spaced far apart, to approach each other, and in the process of approaching, they tend to approach the second boss 8 until the mounting plates 4 are pressed by the second boss 8 and the end plate 11. During and after the pressing process, the wedge-shaped guide bar 12 and the position in contact with it realize the guiding and longitudinal locking, and determine the longitudinal position of the mounting plate 4. In this way, the three-dimensional position of the mounting plate 4 is determined, and the operation is very simple, and the positioning accuracy and positioning reliability are extremely high. The disassembly and assembly space is also increased due to the existence of the swing arm 15, which improves the ease of operation. A locking nut can be set on the second boss 8 to press the screw rod 9 after rotating to the specified position to prevent the screw rod 9 from loosening.

Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
