Description

Technical Field

[0001] This utility model relates to the technical field of plastic packaging film erection equipment, and in particular to an anti-squatting edge erection device. Background Technology

[0002] During production, plastic packaging film is wound onto a cylinder to form a columnar structure. When the wound plastic film is removed from the production equipment, the axis of the columnar plastic film is placed horizontally on the material platform. This facilitates the external packaging protection of the packaging film. After packaging the columnar plastic film, each plastic film needs to be placed upright on a material pallet for easy loading and transportation.

[0003] When changing the cylindrical plastic film from horizontal to vertical placement, it is usually done manually by pulling one end of the film upright. This manual uprighting process can cause the plastic film to buckle at the edges, which can damage packaging films coated with aluminum foil. Utility Model Content

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] Please refer to Figure 1-5 As a specific implementation method, the technical solution of this utility model is: a device for preventing squatting and erecting membrane structures, comprising:

[0031] Column 1, installed vertically;

[0032] The first swing arm 3 is hinged at one end to the column 1 and hinged at the other end to the connecting seat 34;

[0033] The first power telescopic rod 2 is hinged to the first swing arm 3 and is used to drive the first swing arm 3 to swing up and down around the position hinged to the column 1.

[0034] The second swing arm 4 is rotatably connected to the connecting seat 34 at one end and rotatably connected to the rotating beam 5 at the other end. The rotation axis of the second swing arm 4 and the rotation axis of the rotating beam 5 are both set vertically.

[0035] The tilting frame 6 is rotatably mounted on the lower end of the rotating beam 5 about a horizontal axis of rotation;

[0036] The insertion post 7 is set on the tilting frame 6, and the axis of the insertion post 7 is set perpendicular to the rotation axis of the tilting frame 6.

[0037] For details, please refer to Figures 1-5 The bottom of column 1 is fixed to the ground and is vertically installed. A support base 13 is installed at the top of column 1. The first swing arm 3 is rotatably engaged with the support base 13. The other end of the support arm is hinged to a connecting seat 34. Both ends of the first power telescopic rod 2 are hinged to the first swing arm 3 and column 1 respectively. When the first power telescopic rod 2 extends or retracts, it can drive the end of the first swing arm 3 with the connecting seat 34 to swing up and down. The connecting seat 34 rotatably engages with the second swing arm 4. The other end of the second swing arm 4 is rotatably equipped with a rotating beam 5, which can swing along a known axis. A tilting frame 6 is rotatably installed at the lower end of the rotating beam 5. A plug-in post 7 is installed on the tilting frame 6. With this arrangement, during use, the tilting frame 6 is held in place... Figure 1 In the aforementioned state, the insertion post 7 is in a horizontal position. At this time, the height of the insertion post 7 can be adjusted by controlling the extension and retraction of the first power telescopic rod 2, so that the height of the insertion post 7 is equal to the axis of the cylindrical plastic film to be erected. Then, the flipping frame 6 is pushed to make the second swing arm 4 swing, inserting the insertion post 7 into the cylinder at the center of the cylindrical plastic film. Then, the insertion post 7 is locked to the cylinder, and the first power telescopic rod 2 is controlled to retract, causing the connecting seat 34 to rise, which in turn raises the plastic film. After rising to a suitable height, the retraction is stopped, and the flipping frame 6 is controlled to flip, causing the insertion post 7 to flip downward to a vertical position, thereby making the cylindrical plastic film vertical. Then, the first power telescopic rod 2 is controlled to work, causing the connecting seat 34 to descend, placing the cylindrical plastic film on the tray. Then, the insertion post 7 is released from the cylinder, and the first swing arm 3 is controlled to swing, causing the insertion post 7 to rise, completing the erection of the film. The erection device can assist in erecting the film and effectively avoid the problem of the plastic film squatting at the edges.

[0038] Specifically, it should be noted that the reference is... Figure 8One embodiment of the plug-in post 7 is as follows: The plug-in post 7 is a column made of steel, with an internal cavity 70. One end is provided with a third flange 73, which is detachably and fixedly connected to the flipping frame 6. A strip-shaped channel 701 is provided on the side wall of the internal cavity 70. An airbag 72 is provided inside the internal cavity 70. A strip-shaped protrusion corresponding to the channel 701 is provided on the side wall of the airbag 72. The strip-shaped protrusion can be made of hard plastic and includes a friction surface 720. With this arrangement, the airbag 72 can be connected to a high-pressure air source. A control valve is provided between the airbag 72 and the air source. When the part is connected to the atmosphere, the airbag 72 contracts. At this time, the friction surface 720 is located in the channel 701, which facilitates the insertion of the plug 7 into the cylinder and its removal. When the cylinder needs to be locked, the airbag 72 is supplied with air by connecting the air source to the airbag 72, which causes the airbag 72 to expand and push the strip protrusion outward, so that the friction surface 720 abuts against the inner wall of the cylinder. Under the action of friction, the cylinder is locked, achieving the locking effect. It should be noted that the control method for controlling the air source to connect with the airbag 72 and supplying air, and for deflating the airbag 72 in this application adopts the prior art, wherein the high-pressure air source adopts the compressed air supplied in the workshop.

[0039] Furthermore, as a specific implementation method, refer to Figures 1-3 The specific structure of the first swing arm 3 is as follows: The first swing arm 3 includes a first arm 30 and a second arm 31 arranged at intervals. The first arm 30 and the second arm 31 are both hinged to the column 1 through the second pin 32. The ends of the first arm 30 and the second arm 31 are both hinged to the connecting seat 34 through the third pin 33. The two second pins 32 and the two third pins 33 are arranged at intervals in the vertical direction, and the axis connecting line of the two second pins 32 and the axis connecting line of the two third pins 33 are arranged parallel to each other. Specifically, the connecting line between the axes of the two second pins 32 is vertically arranged. Both ends of the first power telescopic rod 2 are provided with first pins 21, which are hinged to the first beam and the support arm 121 respectively. The first pins 21 are parallel to the second pins 32. With this arrangement, when the first power telescopic rod 2 extends and retracts to drive the first arm 30 to swing and drive the second arm 31 to swing synchronously, the vertical posture of the connecting seat 34 is not inconvenient. Therefore, when swinging up and down, the rotating beam 5 can always be kept in a vertical state, ensuring the effective operation of the membrane structure.

[0040] Furthermore, as a specific implementation, the first arm 30 is hinged to a first power telescopic rod 2 at the end of the second pin 32 away from the third pin 33, and the other end of the first power telescopic rod 2 is hinged to the column 1.

The first brake shoe is driven by a cylinder, a hydraulic cylinder, or an electric push rod. With this arrangement, the rotation of the rotating column 12 can be controlled by controlling the locking and unlocking of the first brake shoe on the first friction disc. The rotating column 12 can be locked and released as needed. The cooperation between the brake shoe and the first friction disc can adopt the structure of a disc brake on a vehicle in the prior art, which will not be described in detail here.

[0043] Furthermore, as a preferred embodiment, refer to Figure 1 , Figure 4 , Figure 5 The top of the column 1 is detachably and fixedly connected to a connecting column 11, and the lower end of the rotating column 12 is rotatably engaged with the connecting column 11. Specifically, a first flange 101 is welded to the upper end of the base 10, and a second flange 110 connected to the first flange 101 is welded to the lower end of the connecting column 11. The length of the connecting column 11 is 10cm-30cm. A bearing seat 111 is provided at the upper end of the connecting column 11.

The support shaft 123 passes through the first bearing 124 and the second bearing 125 in sequence. A limit nut 126 is provided at the lower end, thereby realizing the rotational engagement between the rotating column 12 and the base 10. By setting the connecting column 11, the connecting column 11 and the rotating shaft can be assembled, which facilitates the installation and disassembly of the first bearing 124 and the second bearing 125, and facilitates disassembly and maintenance. After connecting the connecting column 11 and the rotating column 12, the connecting column 11 is then connected to the base 10.

[0044] Further, as a specific implementation, the second swing arm 4 has a first rotating shaft 41 at one end and a second bushing 40 at the other end. The axis of the second bushing 40 is parallel to the axis of the first rotating shaft 41, and the rotating beam 5 is rotatably engaged with the second bushing 40. Specifically, the first rotating shaft 41 is rotatably connected to the support base 13, and the upper end of the rotating beam 5 is rotatably engaged with the second bushing 40 with axial anti-movement fitting. The upper end of the rotating beam 5 is coaxially welded with a connecting shaft that engages with the second bushing 40. The engagement structure of the shaft and bushing with rotation and anti-movement fitting is a common structure in the prior art. The engagement method of the rotating beam 5 and the second bushing 40 in this application adopts the prior art.
