A non-standard can roll sealing and positioning device

Abstract

This application relates to a non-standard can roll-sealing positioning device, including a fixed platform. Multiple equidistant movable seats are slidably connected to the top of the fixed platform along its circumference. Multiple equidistant mounting seats are provided above the fixed platform. Positioning wheels are rotatably connected within the mounting seats. During positioning, the non-standard can and a second spring cause the positioning wheels to abut against the outer wall of the non-standard can. The position of the movable sleeve changes, pulling the connecting plate and causing it to move. This aligns the limiting bolt with a limiting screw hole near the fixed plate. The movement of the connecting plate drives the limiting rod and movable block to move. The limiting rod moves and enters the limiting hole to limit the movable sleeve. At this time, rotating the limiting bolt causes it to enter the limiting screw hole to limit the connecting plate, thus completing the positioning of the non-standard can. Subsequent non-standard cans of the same specifications can be positioned directly by driving the movable seats with a cylinder, which in turn drives the positioning wheels to move, facilitating the positioning of non-standard cans.

Description

Technical Field

[0001] This application relates to the technical field of irregular can processing, and in particular to an irregular can roll sealing and positioning device. Background Technology

[0002] Packaging cans (or cylinders) refer to packaging containers with roughly the same cross-sectional shape throughout the can body, a short neck, and an inner diameter of the neck slightly smaller than the inner diameter of the can body, or no neck at all. They are a type of rigid packaging. The packaging material has high strength, and the can body has strong resistance to deformation. The packaging operation involves filling the can and then sealing the opening. They can be used as transport packaging, outer packaging, or commercial packaging and inner packaging.

[0003] With the support of existing technologies, innovation is needed. In the current can manufacturing industry, the roll-sealing technology for cylindrical cans is relatively mature, and uniform roll-sealing pressure distribution can be achieved through rotational symmetry. However, with the increasing market demand for irregularly shaped cans such as square and elliptical cans, traditional roll-sealing equipment cannot adapt to asymmetrical geometries, resulting in frequent positioning deviations during the roll-sealing process. Currently, the industry mainly solves this problem through manual adjustment or customized fixtures, but this is inefficient and inconsistent. Utility Model Content

[0004] To facilitate the positioning of irregularly shaped cans, this application provides a roll-sealing positioning device for irregularly shaped cans.

[0005] This application provides a non-standard can roll-sealing positioning device, which adopts the following technical solution: A non-standard can roll-sealing positioning device includes a fixed platform. Multiple equidistant movable seats are slidably connected to the top of the fixed platform along its circumference. Multiple equidistant mounting seats are provided above the fixed platform. Positioning wheels are rotatably connected inside each mounting seat. A movable sleeve is fixedly connected to the side of each mounting seat near the movable seat. A fixed column is slidably connected to the inner wall of the movable sleeve. One end of the fixed column extending out of the movable sleeve is fixedly connected to the movable seat. Symmetrically distributed guide seats are provided on both sides of the fixed column. The guide seat is fixedly connected to the movable seat, and the guide seat has multiple equidistantly distributed limiting holes. A sliding strip, fixedly connected to the mounting seat, is slidably connected to the inner wall of the guide seat. A fixing plate, fixedly connected to the movable sleeve, is located between two sliding strips. Symmetrically distributed support plates are fixedly connected to the fixing plate. A limiting rod, slidably connected to the sliding strip, is slidably connected to the support plate, and the limiting rod matches the limiting hole. A connecting plate, slidably connected to the movable sleeve, is located on the side of the fixing plate near the mounting seat. Connecting rods are hinged to both sides of the connecting plate, and the other end of the connecting rod is hinged to the limiting rod. By adjusting the distance between the mounting seat and the movable seat, the positions of multiple positioning wheels can be adjusted to adapt to irregularly shaped tanks. The position of the movable sleeve is limited by the limiting rod and limiting holes.

[0006] In a preferred embodiment, the fixed plate has symmetrically distributed sliding grooves, and a movable block is slidably connected to the inner wall of the sliding groove. The movable block is fixedly connected to the limiting rod, and the limiting rod is guided by the sliding groove and the movable block.

[0007] In a preferred embodiment, a first spring is fixedly connected to one side of each of the two movable blocks that are close to each other, and the other end of the first spring is fixedly connected to the inner wall of the slide groove. The first spring enables the limiting rod and the movable block to return to their original positions after they have moved.

[0008] In a preferred embodiment, the movable sleeve has two limiting screw holes, and a limiting bolt is threaded onto the connecting plate. The limiting bolt is adapted to the limiting screw hole. The limiting bolt and the limiting screw hole facilitate the limiting of the connecting plate, and thus facilitate the limiting of the limiting rod.

[0009] In a preferred embodiment, a second spring is fixedly connected to one end of the fixed column that extends into the movable sleeve, and the other end of the second spring is fixedly connected to the mounting base. The second spring facilitates the reset of the mounting base, thereby facilitating the contact between the positioning wheel and the outer wall of the irregularly shaped tank.

[0010] In a preferred embodiment, a plurality of equidistant upright plates are fixedly connected to the top of the fixed platform along its circumference. A cylinder is fixedly connected to the upright plate, and the driving end of the cylinder is fixedly connected to the movable seat. The movable seat is moved by driving the cylinder.

[0011] In summary, this application includes at least one of the following beneficial technical effects: In this invention, during positioning, the movable seat is moved by a cylinder, with multiple cylinders advancing at the same rate. The shaped can and the second spring cause the positioning wheel to abut against the outer wall of the shaped can, changing the position of the movable sleeve. When all positioning wheels have abutted against the outer wall of the shaped can, the connecting plate is pulled to move the connecting plate, aligning the limiting bolt with a limiting screw hole near the fixed plate. The movement of the connecting plate drives the connecting rod to move, causing the limiting rod and the movable block to move. The movement of the movable block deforms the first spring, causing the limiting rod to move and enter the limiting hole to limit the movable sleeve. At this time, rotating the limiting bolt causes it to enter the limiting screw hole to limit the connecting plate, thus completing the positioning of the shaped can. Subsequent shaped cans of the same specifications can be positioned by directly moving the movable seat with a cylinder, which in turn drives the positioning wheel to move, facilitating the positioning of shaped cans.

[0014] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0015] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0016] A non-standard can roll sealing and positioning device includes a fixed platform 1. Multiple equidistant movable seats 2 are slidably connected to the top of the fixed platform 1 along its circumference. Multiple equidistant mounting seats 6 are provided above the fixed platform 1. Positioning wheels 7 are rotatably connected inside the mounting seats 6. A movable sleeve 5 is fixedly connected to the side of the mounting seat 6 near the movable seats 2. A fixed column 4 is slidably connected to the inner wall of the movable sleeve 5. One end of the fixed column 4 extending out of the movable sleeve 5 is fixedly connected to the movable seat 2. Guide seats 9 are symmetrically distributed on both sides of the fixed column 4. The guide seats 9 are fixedly connected to the movable seats 2. Multiple equidistant limiting holes 10 are opened on the guide seats 9. A sliding strip 8 fixedly connected to the mounting seat 6 is slidably connected to the inner wall of the guide seat 9. A fixed plate 11 fixedly connected to the movable sleeve 5 is provided between the two sliding strips 8. A symmetrically distributed support plate 16 is fixedly connected to the fixed plate 11. A limiting rod 17 that is slidably connected to the sliding strip 8 is slidably connected to the support plate 16, and the limiting rod 17 is adapted to the limiting hole 10. A connecting plate 12 that is slidably connected to the movable sleeve 5 is provided on the side of the fixed plate 11 near the mounting seat 6. A connecting rod 15 is hinged on both sides of the connecting plate 12, and the other end of the connecting rod 15 is hinged to the limiting rod 17. By adjusting the distance between the mounting seat 6 and the movable seat 2, the position of multiple positioning wheels 7 can be adjusted to adapt to the irregularly shaped tank. The position of the movable sleeve 5 is limited by the limiting rod 17 and the limiting hole 10.

[0017] The fixed plate 11 has symmetrically distributed sliding grooves, and the inner wall of the sliding groove is slidably connected to the movable block 18, which is fixedly connected to the limiting rod 17. The limiting rod 17 is guided by the sliding groove and the movable block 18.

[0018] Two movable blocks 18 are fixedly connected to a first spring 19 on the side that is close to each other. The other end of the first spring 19 is fixedly connected to the inner wall of the slide groove. The first spring 19 enables the limit rod 17 and the movable block 18 to be reset after they move.

[0019] The movable sleeve 5 has two limit screw holes 14. The connecting plate 12 is threaded with a limit bolt 13, and the limit bolt 13 is adapted to the limit screw hole 14. The limit bolt 13 and the limit screw hole 14 facilitate the limiting of the connecting plate 12, and thus facilitate the limiting of the limit rod 17.

[0020] The fixed column 4 is fixedly connected to a second spring 20 at one end of the movable sleeve 5. The other end of the second spring 20 is fixedly connected to the mounting base 6. The second spring 20 facilitates the reset of the mounting base 6, thereby facilitating the positioning wheel 7 to abut against the outer wall of the irregular tank.

[0021] Multiple equidistant vertical plates 21 are fixedly connected to the top of the fixed platform 1 along its circumference. Cylinders 3 are fixedly connected to the vertical plates 21, and the driving end of the cylinders 3 is fixedly connected to the movable seat 2. The movable seat 2 is moved by driving the cylinders 3.

[0022] Working principle: In this application, there are two limiting screw holes 14, which correspond to the position of the connecting plate 12 when the limiting hole 10 is disengaged from the limiting rod 17 and the position of the connecting plate 12 when the limiting rod 17 enters the limiting hole 10. In this application, during positioning, the movable seat 2 is moved by the cylinder 3. The multiple cylinders 3 have the same thrust. The positioning wheel 7 abuts against the outer wall of the shaped can through the shaped can and the second spring 20. The position of the movable sleeve 5 changes. When all the positioning wheels 7 have abutted against the outer wall of the shaped can, the connecting plate 12 is pulled to move the connecting plate 12, so that the limiting bolt 13 is aligned with a limiting screw hole 14 near the fixed plate 11. The movement of the connecting plate 12 drives the connecting rod 15 to move, so that the limiting rod 17 and the movable block 18 move. The movement of the movable block 18 causes the first spring 19 to deform. The limiting rod 17 moves and enters the limiting hole 10 to limit the movable sleeve 5. At this time, the limiting bolt 13 is rotated so that the limiting bolt 13 enters the limiting screw hole 14 to limit the connecting plate 12, thus completing the positioning of the shaped can. Subsequently, shaped cans of the same specifications can be positioned by directly driving the movable seat 2 to move through the cylinder 3, thereby pushing the positioning wheel 7 to move. This facilitates the positioning of shaped cans. In this application, multiple cylinders 3 are electrically connected to the control panel in actual use, and the propulsion amount of multiple cylinders 3 is controlled by the control panel.

[0023] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
