Description

Technical Field

[0001] This invention relates to the technical field of small round can body processing, specifically a general-purpose production line for small round can body manufacturing. Background Technology

[0002] When manufacturing small round cans, after assembling the can body and bottom cover, the outer circumference of the bottom needs to be machined to form the corresponding shape. Currently, this is generally done through a linear production line. Linear production lines occupy relatively long workshop spaces and have high requirements for the workshop. In addition, existing small round cans generally require transfer tools to be transferred when entering the production line, which directly leads to high transfer costs. Therefore, there is an urgent need to develop a universal workstation production line for small round can bodies to reduce the space requirements of the workshop and reduce transfer costs. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a universal workstation production line for small round can bodies, which allows the production line to be arranged in a small workshop and eliminates the need for additional transfer equipment during transport, thereby reducing the space requirements of the workshop and lowering transport costs.

[0004] A universal production line for manufacturing small round can bodies, characterized in that it comprises:

[0005] A frame is provided with a positioning plate, a vertical rotating shaft is provided at the center of the positioning plate, a rotating frame is provided on the positioning plate, the upper output end of the vertical rotating shaft is connected to the rotating frame, a rotating motor is fixedly connected to the lower part of the vertical rotating shaft, and a number of inner mold installation stations are evenly distributed around the circumference of the rotating frame, and a corresponding inner mold is fixedly installed at each inner mold installation station.

[0006] Input the belt cable;

[0007] And the output belt cable;

[0008] The upper surface of the positioning disk has an input notch at one radial position and an output notch at another radial position. The input belt is inclined at an angle α along the width direction and extends to the position of the input notch. The positioning disk has a transition slope at the connection position of the input notch. The transition slope is used to guide the small round can into the processing area of ​​the upper surface of the positioning disk. The input end of the output belt is located at the output notch. The positioning disk has a guide slope at the connection position of the output notch. The guide slope guides the small round can into the input end of the output belt at the output notch.

[0009] The upper surface of the positioning disk is provided with a fixed-position annular outer mold, and the outer mold and several inner molds are combined to process the small round can body;

[0010] Each set of inner molds is fixed to the inner mold installation position of the rotating frame by the installation head. Each installation head includes an upper small gear, and an inner gear ring is provided on the periphery formed by the combination of several small gears. The inner gear ring is fixed at the height of the outer collar. The small gears mesh with and connect the inner gear ring. During the rotation of the rotating frame, all the small gears rotate, thereby driving the inner mold to rotate and performing shaping operations on the small round can body.

[0011] The outer mold is provided with an avoidance notch groove corresponding to the input notch position of the positioning plate. The output notch of the positioning plate is lower than the lower surface of the outer mold to ensure that the small round can body flows out along the output belt line.

[0012] Its further features are:

[0013] The inner and outer molds of each group are at the same height and horizontal level facing the small round can body for can body processing and shaping operations;

[0014] The outer collar is fixed to the lower positioning collar by several support blocks. The positioning collar is sleeved on the outer periphery of the positioning disk. The positioning collar is provided with installation notches corresponding to the output end of the input belt and the input end of the output belt.

[0015] The mounting head includes a fixed frame, a pinion assembly, a hollow assembly shaft, a stop cover, and a push pin. The stop cover, pinion assembly, and fixed frame are stacked sequentially from top to bottom. The hollow assembly shaft includes a shaft body, a bottom stop side protrusion, and a support ring. The support ring is sleeved on the bottom of the shaft body. The pinion assembly includes a bushing and a pinion. The pinion is fixed to the upper outer circumference of the bushing. The fixed frame is used to fix the mounting head to the corresponding inner mold mounting position of the rotating frame. The fixed frame includes an upper fixed plate, a central mounting cavity, an upper bearing, and a lower bearing. The upper bearing is provided on the upper outer ring of the central mounting cavity, and the lower outer ring of the central mounting cavity is provided with... The lower bearing has a shaft that runs from bottom to top through the central mounting cavity and the inner cavity of the bushing, and is then threaded to the inner thread of the outer ring. The upper part of the support ring is tightly attached to the inner ring of the lower bearing. A linear guide spring is fitted on the lower small diameter end. The push pin is located in the central inner cavity of the shaft. The linear guide spring is located in the large diameter cavity, and the lower part of the linear guide spring is mounted on the lower wall of the large diameter cavity. The upper part of the linear guide spring is mounted on the lower surface of the upper large diameter end. When the linear guide spring is not compressed, the upper surface of the upper large diameter end is attached to the lower surface of the upper end plate, and the top convex end protrudes from the central hole. The lower surface of the support ring is used to press and attach the upper surface of the inner mold.

[0016] The upper surface of the outer collar is covered with a ring plate. A pusher protrusion is provided on the ring plate at the position directly above the guide slope. The pusher protrusion is used to push the pusher pin and disengage the product from the inner mold, so that the product falls.

[0017] With this invention, the small round can enters the input notch along the input belt line. After the inner mold rotates, one end presses against the inner wall of the small round can at its height position. Then, it drives the small round can to rise along the transition slope until the small round can rises to the upper surface of the positioning plate to complete the loading operation. Afterward, the inner mold revolves around the vertical rotation axis and rotates on its own axis. It works with the outer mold to shape the small round can. Finally, the small round can falls down along the guide slope to the output belt line corresponding to the output notch and is sent out. It only requires a ring structure on the machine to set up a production line in a small workshop. Moreover, no additional transfer equipment is needed during the transfer process, which reduces the space requirements of the workshop and reduces the transfer cost. Attached Figure Description

Detailed Implementation

[0034] A general-purpose production line for manufacturing small round can bodies, see Figures 1-11 It includes a frame 100, an input belt conveyor 200, and an output belt conveyor 300; both the input belt conveyor 200 and the output belt conveyor 300 are equipped with independent conveyor motors;

[0035] A positioning disk 1 is provided on the frame 100. A vertical rotating shaft 2 is provided at the center of the positioning disk 1. A rotating frame 3 is provided on the positioning disk 1. The upper output end of the vertical rotating shaft 2 is connected to the rotating frame 3. The lower part of the vertical rotating shaft 2 is connected to a rotating motor 5 through a coupling 4. Several inner mold installation stations 6 are evenly distributed around the circumference of the rotating frame 3. A corresponding inner mold 500 is fixedly installed on each inner mold installation station 6.

[0036] The upper surface of the positioning disk 1 has an input notch 101 at one radial position and an output notch 102 at another radial position. The input belt 200 is inclined at an angle α along the width direction. In specific implementation, the value of α is 10° to 15° to ensure reliable and stable conveying.

[0037] The input belt 200 extends to the input notch 101. The positioning disk 1 is provided with a transition slope 8 at the connection position of the input notch 101. The transition slope 8 is used to guide the small round can body 400 into the upper surface processing area of ​​the positioning disk 1. The input end of the output belt 300 is located at the output notch 102. The positioning disk 1 is provided with a guide slope 9 at the connection position of the output notch 102. The guide slope 9 guides the small round can body 400 into the input end of the output belt 300 at the output notch 102.

[0038] The upper surface of the positioning disk 1 is provided with a fixed-position annular outer mold 600, and the outer mold 600 and several inner molds 500 are combined to process the small round can body 400.

[0039] Each set of inner molds 500 is fixed to the inner mold mounting station 6 of the rotating frame 3 via a mounting head 700. Each mounting head 700 includes an upper small gear 22. An inner gear ring 800 is also provided on the periphery formed by the combination of several small gears 22. The inner gear ring 800 is fixed at the height of the outer collar 900. The small gears 22 mesh with the inner gear ring 800. During the rotation of the rotating frame 3, the small gears 22 revolve around the central axis. Then, due to the presence of the inner gear ring 800, all the small gears 22 rotate on their own axis, thereby driving the inner mold 500 to rotate and perform shaping operations on the small round can body 400.

[0040] The outer mold 600 is provided with an avoidance notch groove 601 corresponding to the input notch 101 position of the positioning disk 1. The output notch 102 of the positioning disk 1 is lower than the lower surface of the outer mold 600 to ensure that the small round can body 400 flows out along the output belt line 300.

[0041] In practice:

[0042] The input belt 200 is arranged perpendicular to the output belt 300. The sizing arc distance of the small round tank body is about 270°. Three internal mold installation stations 6 are set on the entire rotating frame 3.

[0043] The inner mold 500 and the outer mold 600 of each group are at the same height and horizontal face to perform the can body processing and shaping operation of the small round can body 400;

[0044] The outer collar 900 is fixed to the lower positioning collar 1000 by a number of support blocks 901. The positioning collar 1000 is sleeved on the outer periphery of the positioning disk 1. The positioning collar 1000 is provided with an installation notch 1001 corresponding to the output end of the input belt 200 and the input end of the output belt 300.

[0045] The mounting head 700 includes a fixed frame 10, a pinion assembly 20, a hollow assembly shaft 30, a stop cover 40, and a pusher pin 50. The stop cover 40, pinion assembly 20, and fixed frame 10 are stacked sequentially from top to bottom. The hollow assembly shaft 30 includes a shaft body 31, a bottom stop side protrusion 32, and a support ring 33. The support ring 33 is sleeved on the bottom of the shaft body 31, and the bottom stop side protrusion 32 is provided at the bottom of the shaft body 31. The pinion assembly 20 includes a bushing 2. 1. A small gear 22 is fixed to the upper outer periphery of the bushing 21. The fixed frame 10 is used to fix the mounting head 700 to the corresponding inner mold mounting position 6 of the rotating frame. The upper outer periphery of the top of the shaft 31 has an external thread structure. The central inner cavity of the shaft 31 is a cavity that is larger at the top and smaller at the bottom, including a large-diameter cavity 34 at the top and a small-diameter cavity 35 at the bottom. A bottom stop side protrusion 32 is provided on the bottom outer periphery of the shaft 31. The bottom stop side protrusion 32 is used to position the inner mold 500.

[0046] The stop cover 40 includes an upper end plate 41 and an outer ring sleeve 42. The upper end plate 41 is provided with a central hole 411, and the inner circumference of the outer ring sleeve 42 is provided with an internal thread. In a specific embodiment, the bottom of the outer ring sleeve 42 of the stop cover is a side-convex fitting outer ring 421. The lower surface of the fitting outer ring 421 is in close contact with the center surface of the pinion 22 to ensure a stable and reliable press-fit connection. In a preferred embodiment, the stop cover 40 is a specially designed locking nut structure, which ensures a stable and reliable threaded connection.

[0047] The pusher pin 50 includes a top convex end 51, an upper large-diameter end 52, and a middle and lower small-diameter end 53;

[0048] The stop cover 40, pinion assembly 20, and fixed frame 10 are stacked sequentially from top to bottom. A support ring 33 is fitted above the bottom of the shaft 31. The shaft 31 passes through the inner cavity of the central mounting cavity 12 and the bushing 21 from bottom to top and is then threaded to the inner thread of the outer ring 42. The outer wall of the shaft 31 is fitted to the inner rings of the upper bearing 13 and the lower bearing 14. The upper part of the support ring 33 is tightly fitted to the inner ring of the lower bearing 14. A linear guide spring 60 is fitted at the lower small diameter end 53. The pusher pin 50 is located at... The linear guide spring 60 is located in the large-diameter cavity 34 in the central cavity of the shaft body 31. The lower part of the linear guide spring 60 is mounted on the lower wall of the large-diameter cavity 34, and the upper part of the linear guide spring 60 is mounted on the lower surface of the upper large-diameter end 52. When the linear guide spring 60 is not compressed, the upper surface of the upper large-diameter end 52 is in contact with the lower surface of the upper end plate 41, and the top convex end 51 protrudes from the central hole 411. The lower surface of the support ring 33 is used to press and attach the upper surface of the mold 500 in the mold assembly.

[0049] The upper surface of the outer ring 900 is covered with a ring plate 1100. The ring plate 1100 is provided with a pusher protrusion 7 at the position directly above the guide slope 9. The pusher protrusion 7 is used to push the pusher needle 50 and disengage the small round can body 400 from the inner mold 500, so that the small round can body 400 falls.

[0050] Its working principle is as follows: the small round can enters the input gap along the input belt line. After the inner mold rotates, one end presses against the inner wall of the small round can at the height position. Then, it drives the small round can to rise along the transition slope until the small round can rises to the upper surface of the positioning plate to complete the feeding operation. After that, the inner mold revolves around the vertical rotation axis as the central axis and rotates on its own axis at the same time. It works with the outer mold to perform the shaping operation of the small round can. The pusher is used to push the pusher pin to remove the small round can from the inner mold. After the small round can is pushed off the inner mold, it falls along the guide slope to the output belt line corresponding to the output gap and is sent out. It only sets a ring structure on the machine, which allows the production line to be set up in a small workshop. Moreover, no additional transfer equipment is required during the transfer process, which reduces the space requirements of the workshop and reduces the transfer cost.
