Description

Technical Field

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

[0002] Plastic packaging film is a flexible plastic material widely used in daily life and industry. It is mainly used for wrapping, protecting, sealing or displaying products. After the plastic packaging film is produced, it needs to be wound onto a roll for transportation and storage. However, the film roll is usually placed horizontally after winding. When transportation is required, the film roll needs to be stood upright.

[0003] The traditional method of erecting film is manual. When erecting film, people usually pull one end of the cylindrical plastic film to stand it up. However, manual erection is not only labor-intensive, but also prone to causing edge damage to the ends of the roll material. Therefore, relevant professionals have developed a special device for erecting film. Using the erection device can not only reduce the labor intensity of erecting film, but also avoid edge damage to the ends of the roll material to a certain extent.

[0004] A membrane erection device generally consists of columns, booms, and a tilting structure. The tilting structure is equipped with fixing components for securing the membrane roll. During membrane erection, the fixing components secure the membrane roll to the tilting structure, which then completes the tilting and erection process. However, due to the weight and smooth surface of the membrane roll, coupled with the generally low reliability of the fixing structure, there is a risk of the membrane roll slipping during the tilting and erection process, which could cause the membrane roll to fall to the ground and become damaged. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the existing flipping structure has a poor gripping and fixing effect on the roll material, and to propose a flipping structure and an anti-squatting edge film device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A flipping structure and anti-squatting edge-standing film device include a support frame, a flipping frame rotatably connected to the lower part of the support frame, and a first power telescopic rod connected between the flipping frame and the support frame. An insert post is connected to the outside of the flipping frame for inserting into the roll at the center of the roll material. The insert post is hollow inside and has an internal fixing mechanism for fixing the insert post to the roll material. Several external fixing mechanisms are also connected to the outside of the flipping frame for clamping and fixing the roll material.

[0007] In some embodiments, the internal fixing mechanism includes an airbag and a plurality of friction block assemblies. A first connecting pipe is fixed to the outside of the airbag for connecting the airbag to an external air source. A plurality of through grooves extending into the inside are opened on the outer surface of the insert. The plurality of friction block assemblies are all connected to the outer surface of the airbag and are slidably connected in the plurality of through grooves respectively.

[0008] In some embodiments, the friction block assembly includes a compression block and a friction block, both of which are wedge-shaped and their inclined surfaces are arranged opposite each other. The compression block is connected to an airbag, the outer surface of the friction block is in contact with the inner wall of the drum, and a connecting spring is connected between the compression block and the friction block.

[0009] In some embodiments, a plurality of first pointed protrusions are fixed on the inclined surface of the extrusion block, the first pointed protrusions slide through the friction block, and a second pointed protrusion is fixed on the outer surface of the friction block. The first pointed protrusions and the second pointed protrusions are used to increase the friction between the friction block assembly and the drum.

[0010] In some embodiments, the external fixing mechanism includes a fixing beam with a hollow interior, a clamping assembly on the fixing beam, and a pneumatic transmission assembly inside the fixing beam for driving the clamping assembly.

[0011] In some embodiments, the clamping assembly includes a slider slidably connected inside the fixed beam, one end of which is fixed with a clamping plate for clamping the roll material, and the other end is connected to the fixed beam with a first return spring.

[0012] In some embodiments, the pneumatic transmission assembly includes a pneumatic telescopic mechanism fixed within a fixed beam and a sliding rod slidably connected within the fixed beam. A second connecting pipe is externally connected to the pneumatic telescopic mechanism. The telescopic end of the pneumatic telescopic mechanism is fixed to the sliding rod and is used to drive the sliding rod to slide. A second return spring is connected between the sliding rod and the fixed beam.

[0013] In some embodiments, a wedge-shaped top block is fixed to the outside of the sliding rod, and the wedge-shaped inclined surface of the top block is used to push the slider to slide.

[0014] An anti-squatting edge-standing membrane device includes a column, a boom rotatably connected to the upper part of the column, a second power telescopic rod connected between one end of the boom and the column, and a swing arm rotatably connected to the other end of the boom. The flipping structure is rotatably connected to the lower part of the swing arm.

[0015] Compared with the prior art, the present invention provides a flipping structure and an anti-squatting edge membrane device, which has the following beneficial effects.

[0016] 1. In this utility model, the internal fixing mechanism can double the friction between the insertion post and the inner wall of the roll by the extrusion block and the friction block, thereby improving the fixing ability of the roll material. Moreover, when the roll material is flipped and erected, the first pointed protrusion inserted into the roll material is facing diagonally upward, which can effectively prevent the roll material from sliding down and thus improve the stability of the roll material when flipping and erecting the film.

[0017] 2. This utility model, through the setting of an external fixing mechanism, not only fixes the inside of the roll through the internal fixing mechanism, but also achieves the purpose of fixing the outside of the roll material. This can effectively prevent the roll material from slipping or rotating during the film erection process, thereby ensuring the stability of the roll material during the film erection process, and further improving the fixing effect of the roll material, thus preventing damage caused by the roll material slipping, and avoiding corresponding losses.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1 A flipping structure includes a support 10, a flipping frame 11 rotatably connected to the lower part of the support 10, and a first power telescopic rod 12 connected between the flipping frame 11 and the support 10. An insertion post 14 is connected to the outside of the flipping frame 11 for insertion into the roll 61 at the center of the roll material 60. The insertion post 14 is hollow inside and has an internal fixing mechanism 15 for fixing the insertion post 14 to the roll 61. Several external fixing mechanisms 16 are also connected to the outside of the flipping frame 11 for clamping and fixing the roll material 60. The several external fixing mechanisms 16 are arranged divergently along the axis of the insertion post 14, and preferably two external fixing mechanisms are symmetrically distributed.

[0028] Reference Figure 2-5 The internal fixing mechanism 15 includes an airbag 151 and several friction block assemblies 153. The airbag 151 is fixed with a first connecting pipe 152 for connecting the airbag 151 to an external air source. The outer surface of the insert 14 is provided with several through grooves 141 extending into the interior. The several friction block assemblies 153 are all connected to the outer surface of the airbag 151 and are slidably connected in the several through grooves 141 respectively.

[0029] The friction block assembly 153 includes a compression block 1531 and a friction block 1532. Both the compression block 1531 and the friction block 1532 are wedge-shaped and their inclined surfaces are arranged opposite each other. The compression block 1531 is connected to the airbag 151. The outer surface of the friction block 1532 is in contact with the inner wall of the drum 61, and a connecting spring 1533 is connected between the compression block 1531 and the friction block 1532.

[0030] Several first pointed protrusions 1534 are fixed on the inclined surface of the extrusion block 1531, and the first pointed protrusions 1534 gradually tilt towards the flipping frame 11. The first pointed protrusions 1534 slide through the friction block 1532, and the outer surface of the friction block 1532 is fixed with second pointed protrusions 1535. The first pointed protrusions 1534 and the second pointed protrusions 1535 are used to increase the friction between the friction block assembly 153 and the drum 61.

[0031] Reference Figure 2 and 6 The external fixing mechanism 16 includes a fixed beam 161 with a hollow interior. The fixed beam 161 is provided with a clamping assembly 164, and the interior of the fixed beam 161 is provided with a pneumatic transmission assembly 162 for driving the clamping assembly 164. Multiple clamping assemblies 164 can be provided along the length of the fixed beam 161 as needed to ensure the clamping effect.

[0032] The clamping assembly 164 includes a slider 1641 slidably connected inside the fixed beam 161. One end of the slider 1641 is fixed with a clamping plate 1642 for clamping the roll 60, and the other end is connected to the fixed beam 161 with a first return spring 1644.

[0033] The pneumatic transmission assembly 162 includes a pneumatic telescopic mechanism 17 fixed in the fixed beam 161 and a sliding rod 1624 slidably connected in the fixed beam 161. The pneumatic telescopic mechanism 17 is externally connected to a second connecting pipe 163. The telescopic end of the pneumatic telescopic mechanism 17 is fixed to the sliding rod 1624 and is used to drive the sliding rod 1624 to slide. A second return spring 1626 is connected between the sliding rod 1624 and the fixed beam 161.

[0034] The pneumatic telescopic mechanism 17 includes an air cylinder 1621, which is connected to the second connecting pipe 163. A piston 1622 is slidably connected inside the air cylinder 1621. A piston rod 1623, which is fixed to the sliding rod 1624, is fixed on the piston 1622 and is used to drive the sliding rod 1624 to slide.

[0035] A wedge-shaped top block 1625 is fixed to the outside of the sliding rod 1624. The wedge-shaped inclined surface of the top block 1625 is used to push the slider 1641 to slide.

[0036] The slider 1641 has a through hole 1645 inside, and a roller 1643 is rotatably connected inside the through hole 1645. The top block 1625 slides inside the through hole 1645, and the wedge-shaped inclined surface of the top block 1625 contacts the roller 1643.

[0037] Reference Figure 7 An anti-squatting edge-standing membrane device includes a column 20, a boom 30 rotatably connected to the upper part of the column 20, a second power telescopic rod 40 connected between one end of the boom 30 and the column 20, and a swing arm 50 rotatably connected to the other end of the boom 30. A flipping structure is rotatably connected to the lower part of the swing arm 50.

[0038] In this invention, when erecting the horizontally placed roll 60, the boom 30 is first lifted or lowered by extending and retracting the second power telescopic rod 40 to adjust the height of the flipping structure. The horizontal position of the flipping structure is then adjusted by rotating the swing arm 50. Finally, the orientation of the insertion post 14 and the external fixing mechanism 16 is adjusted by controlling the bracket 10 to rotate on the swing arm 50, thereby aligning the insertion post 14 with the inner hole of the roll 61 at the center of the roll 60. The insertion post 14 is then inserted into the inner hole of the roll 61, and the air bladder 151 and the air cylinder 1621 are inflated by an external air source.

[0039] like Figure 5 As shown, when the airbag 151 is not inflated, the compression block 1531 and the friction block 1532 do not contact each other under the support of the connecting spring 1533. When the airbag 151 is inflated, it will expand and deform to a certain extent, and push the compression block 1531 to slide. The compression block 1531 then pushes the friction block 1532 to slide through the connecting spring 1533 until the friction block 1532 contacts the inner wall of the roll 61. The friction block 1532 then compresses the inner wall of the roll 61. In addition, the second pointed protrusion 1535 can increase the friction between the friction block 1532 and the inner wall of the roll 61, thereby improving the fixing ability of the roll 60. Then, under the push of the airbag 151, the squeezing block 1531 will continue to slide until it contacts the friction block 1532. During this process, the connecting spring 1533 will be compressed to a certain extent, and the first pointed protrusion 1534 will be inserted into the inner wall of the drum 61 at an angle. This will further increase the friction between the friction block assembly 153 and the drum 61, thereby improving the fixing effect between the insert 14 and the drum 61, and thus improving the fixing ability of the roll 60.

[0040] After the air cylinder 1621 is inflated, the piston 1622 pushes the piston rod 1623 and the sliding rod 1624 to slide, compressing the second return spring 1626. At the same time, the top block 1625 slides with the sliding rod 1624 and pushes the slider 1641 and the clamping plate 1642 towards the roll material 60 through the roller 1643. During this process, the first return spring 1644 is stretched until the clamping plate 1642 contacts the roll material 60. The outer clamping plate 1642 can then clamp and fix the roll material 60, thereby achieving the purpose of fixing the exterior of the roll material 60. This can effectively prevent the roll material 60 from slipping or rotating during the film erection process, and further support and stabilize the roll material 60, thereby further improving the fixing effect of the roll material 60, preventing damage caused by the roll material 60 slipping, and avoiding corresponding losses.

[0041] After the roll material 60 is fixed, the retraction of the first power telescopic rod 12 is controlled by a certain distance, which can pull the flipping frame 11 to rotate 90 degrees. This allows the roll material 60 to be flipped synchronously through the insert post 14 and the external fixing mechanism 16, thus realizing the flipping and erecting of the film. Moreover, when the roll material 60 is flipped and erected, the first pointed protrusion 1534 inserted into the roll 61 is facing diagonally upward, which can further prevent the roll material 60 from sliding down and further improve the stability of the roll material 60 when flipping and erecting the film.

[0042] After placing the roll 60 in the appropriate position, deflate the airbag 151 and the air cylinder 1621 through an external air source. Then, the friction block assembly 153 will reset under the rebound force of the airbag 151, the clamping assembly 164 will also reset under the elastic force of the first reset spring 1644, and the sliding rod 1624 will also reset under the elastic force of the second reset spring 1626. Finally, the insert 14 can be pulled out from the roll 61.
