Description

Technical Field

[0001] This invention relates to the field of stretch wrapping technology, specifically to a linear stretch wrapping device. Background Technology

[0002] After solid metal cylinders are manufactured, they need to be wrapped with wire. The purposes of using wire wrapping are: wire wrapping can provide an extra protective layer, wire wrapping can provide better stability for solid metal cylinders, and wire wrapping can keep solid metal cylinders clean. This is especially important for industries with special requirements, such as food, pharmaceuticals or semiconductors.

[0003] When solid metal cylinders are used for line winding packaging, the curved surface of the solid metal cylinder may cause the film to fall off due to excessive winding force. In addition, if the film is not wrapped tightly enough, the film winding effect on the solid metal cylinder will be poor. Summary of the Invention

[0004] Therefore, the present invention provides a linear winding packaging device that solves the above-mentioned technical problems.

[0005] The present invention provides a linear winding packaging device, comprising a base, a placement unit and a winding unit.

[0007] An anti-detachment mechanism is used to prevent the film from falling off when wrapping the edge of a solid metal cylinder. The anti-detachment mechanism is mounted on the clamping mechanism.

[0008] The clamping mechanism includes an adaptive component located on the right side of the base. Two symmetrical fixed columns are fixedly connected to the adaptive component, and a fitting component is provided on both fixed columns.

[0009] The anti-detachment mechanism includes an adjusting component located at the middle position above the winding unit, and auxiliary components are provided on both the front and rear sides above the winding unit. A pressing component is provided on both the adjusting component and the auxiliary components.

[0010] According to an embodiment of the present invention, the adaptive component includes a connecting groove formed on the right side of the base. Two elastic connecting telescopic rods symmetrically arranged front and rear are fixedly connected to the inner wall of the left side of the connecting groove. The right ends of the two elastic connecting telescopic rods are jointly fixedly connected to a sliding plate. The sliding plate is slidably connected to the connecting groove. The right end of the upper surface of the sliding plate is fixedly connected to a fixed column.

[0011] According to an embodiment of the present invention, the bonding component includes two symmetrical arc-shaped connecting plates fixedly connected to two fixed columns. Multiple evenly distributed mounting grooves are provided on the opposite surfaces of the two arc-shaped connecting plates. Sliding blocks are slidably connected inside the mounting grooves. A connecting spring is provided between the sliding blocks and the inner wall of the mounting groove. An extrusion roller is rotatably connected between the two vertically distributed sliding blocks.

[0012] According to an embodiment of the present invention, the adjusting member includes an electric telescopic rod fixedly connected to an upper arc-shaped connecting plate, a sliding rail fixedly connected to the top end of the electric telescopic rod, and an electric slider slidably connected to the outer surface of the sliding rail.

[0013] According to an embodiment of the present invention, the clamping member includes a connecting horizontal plate fixedly connected to the lower surface of the electric slider. Each of the four corners of the lower surface of the connecting horizontal plate is fixedly connected to an elastic telescopic connecting seat. The bottom ends of the two elastic telescopic connecting seats distributed on the left and right are fixedly connected to a fixing frame.

[0015] According to an embodiment of the present invention, the top ends of the two adjusting slide rods are fixedly connected to a fixed bracket, and the bottom end of the fixed bracket is fixedly connected to the upper surface of the arc-shaped connecting plate.

[0016] The technical solution of this invention is as follows: 1. By setting up an anti-detachment mechanism, when the film is wound on the solid metal cylinder, the film on the edge of the solid metal cylinder can be pressed in time when the film is wound to the edge of the solid metal cylinder, so as to avoid the film slipping off the solid metal cylinder due to the continuous tension when the film is wound on the edge of the solid metal cylinder, thus ensuring the normal progress of the winding work.

[0017] 2. By setting up a pressing mechanism, the film wrapped on the solid metal cylinder can be squeezed in time during the film winding process, so that the film can adhere tightly to the solid metal cylinder after being wound, improving the uniformity of film winding on the solid metal cylinder, and also making the film winding effect better.

Detailed Implementation

[0029] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] like Figure 1 and Figure 2 As shown, a linear wrapping packaging device includes a base 1, a placement unit 2, and a wrapping unit 4. The upper surface of the base 1 is rotatably connected to the placement unit 2 for placing the solid metal cylinder to be wrapped, and the rear side of the base 1 is fixedly connected to the wrapping unit 4 for conveying the wrapping film.

[0031] A clamping mechanism 5 is used to press the position of a solid metal cylinder after it has been wrapped with a film. The clamping mechanism 5 is mounted on the base 1.

[0032] An anti-detachment mechanism 3 is used to prevent the film from falling off when wrapping the edge of a solid metal cylinder. The anti-detachment mechanism 3 is installed on the pressing mechanism 5.

[0033] like Figure 3 and Figure 4 As shown, the clamping mechanism 5 includes an adaptive component 51 located on the right side of the base 1. Two symmetrical fixed columns 52 are fixedly connected to the adaptive component 51, and a fitting component 53 is provided on both fixed columns 52.

[0034] like Figure 4 and Figure 5As shown, the adaptive component 51 includes a connecting groove 512 opened on the right side of the base 1. Two elastic connecting telescopic rods 513 symmetrically connected to the left inner wall of the connecting groove 512 are fixedly connected. The right ends of the two elastic connecting telescopic rods 513 are fixedly connected to a sliding plate 511. The sliding plate 511 is slidably connected to the connecting groove 512. The right end of the upper surface of the sliding plate 511 is fixedly connected to the fixed column 52.

[0035] like Figure 3 , Figure 4 and Figure 6 As shown, the bonding component 53 includes two symmetrical arc-shaped connecting plates 531 fixedly connected to two fixed columns 52. Multiple evenly distributed mounting grooves 533 are provided on the opposite surfaces of the two arc-shaped connecting plates 531. Sliding blocks 534 are slidably connected inside the mounting grooves 533. A connecting spring is provided between the sliding blocks 534 and the inner wall of the mounting grooves 533. The two sliding blocks 534 distributed vertically are rotatably connected to a squeezing roller 532.

[0036] In practical use, the solid metal cylinder is first placed on the placement unit 2. The position of the anti-detachment mechanism 3 is then adjusted so that it is positioned above the edge of the solid metal cylinder. Then, the winding unit 4, in conjunction with the placement unit 2, rotates on the base 1 to begin film winding onto the surface of the solid metal cylinder on the placement unit 2. During the winding process, as the solid metal cylinder passes the extrusion roller 532, the extrusion roller 532 rotates on the sliding block 534. Because the solid metal cylinder is not circular, as it rotates with the placement unit 2 and passes the extrusion roller 532, it generates a pushing force on the extrusion roller 532. At this time, the extrusion roller 532 pushes the sliding block 534 to slide inside the mounting groove 533, and the extrusion roller 532 is connected by the arc-shaped connecting plate 531. The sliding plate 511 slides inside the base 1. At this time, the connecting spring is deformed by the force, and the connecting groove 512 is compressed. When the solid metal cylinder does not exert a pushing force on the extrusion roller 532, the sliding plate 511 and the extrusion roller 532 are restored to their original positions under the action of the elastic force of the connecting spring and the connecting groove 512. This ensures that the extrusion roller 532 is always in contact with the winding surface of the solid metal cylinder. It should be noted that there are multiple extrusion rollers 532. During the rotation, the solid metal cylinder will pass through the extrusion rollers 532 at different positions on the arc-shaped connecting plate 531. After being pushed, the extrusion roller 532 at each position will push the sliding block 534 to slide inside the mounting groove 533 and the sliding plate 511 to slide inside the connecting groove 512.

[0037] like Figure 7 As shown, the anti-detachment mechanism 3 includes an adjustment component 32 located at the middle position above the winding unit 4, and auxiliary components 33 located at the front and rear sides above the winding unit 4. A pressing component 31 is provided on both the adjustment component 32 and the auxiliary components 33.

[0038] like Figure 7 and Figure 8 As shown, the adjusting component 32 includes an electric telescopic rod 323 fixedly connected to the upper arc-shaped connecting plate 531. The top end of the electric telescopic rod 323 is fixedly connected to a sliding rail 322, and an electric slider 321 is slidably connected to the outer surface of the sliding rail 322.

[0039] like Figure 7 and Figure 8 As shown, the clamping component 31 includes a connecting horizontal plate 314 fixedly connected to the lower surface of the electric slider 321. Each of the four corners of the lower surface of the connecting horizontal plate 314 is fixedly connected to an elastic telescopic connecting seat 315. The bottom ends of the two elastic telescopic connecting seats 315 distributed on the left and right are fixedly connected to a fixing frame 313. The bottom ends of the two fixing frames 313 are fixedly connected to two left and right symmetrical mounting plates 312. A rotating belt 311 is rotatably connected between the opposite surfaces of the two mounting plates 312.

[0040] like Figure 7 and Figure 8 As shown, the auxiliary component 33 includes two connecting columns 332 fixedly connected to the front and rear ends of the upper surface of the connecting horizontal plate 314. A telescopic connecting rod 331 is fixedly connected to the top of the connecting column 332. A vertically penetrating connecting hole is opened at the end of the telescopic connecting rod 331 away from the connecting column 332. An adjusting slide rod 333 is slidably connected inside the connecting hole. The bottom end of the adjusting slide rod 333 is fixedly connected to the upper surface of the arc-shaped connecting plate 531. The top ends of the two adjusting slide rods 333 are fixedly connected to a fixed bracket. The bottom end of the fixed bracket is fixedly connected to the upper surface of the arc-shaped connecting plate 531.

[0041] In practical use, when the position of the anti-detachment mechanism 3 is adjusted after the solid metal cylinder is placed, the electric slider 321 first slides on the sliding track 322 to adjust the left and right position of the connecting horizontal plate 314, so that the rotating belt 311 on the connecting horizontal plate 314 is above the edge of the solid metal cylinder. Then, the electric telescopic rod 323 pushes the sliding track 322 up and down, so that the lower surface of the rotating belt 311 on the connecting horizontal plate 314 is in contact with the top edge of the solid metal cylinder. When adjusting the left and right position of the rotating belt 311, the telescopic connecting rod 331 telescopically moves the connecting horizontal plate 314 left and right. When adjusting the up and down position of the rotating belt 311, the telescopic connecting rod 331 slides up and down on the adjusting slide rod 333 to move the connecting horizontal plate 314 up and down.

[0042] When the film winding begins on the solid metal cylinder, the lower surface of the rotating belt 311 is in contact with the top of the solid metal cylinder. As the solid metal cylinder begins to rotate, the rotating belt 311 can rotate on the mounting plate 312, allowing the top of the solid metal cylinder to slide more smoothly against the lower surface of the rotating belt 311 without damaging the film wound on the solid metal cylinder. At this point, when the film begins to be wound around the edge of the solid metal cylinder, after the film is wound around the edge of the solid metal cylinder, the rotating belt 311 can... Pressing the film firmly onto the edge of the solid metal cylinder in a timely manner can prevent the film from slipping off the edge of the solid metal cylinder. At the same time, under the action of the elastic telescopic connector 315, after the rotating belt 311 is attached to the edge of the solid metal cylinder, the elastic telescopic connector 315 still has a certain distance to move. This ensures that the rotating belt 311 is tightly attached to the top of the solid metal cylinder, while preventing the rotating belt 311 from being too tightly attached to the edge of the solid metal cylinder as the film wraps around it, which would affect the normal winding of the film.

[0043] Working principle: In actual use, the solid metal cylinder is first placed on the placement unit 2. At this time, the position of the clamping member 31 is adjusted by the adjusting member 32 so that the clamping member 31 is above the edge of the solid metal cylinder. Then, the winding unit 4 cooperates with the placement unit 2 to rotate on the base 1 to start film winding on the surface of the solid metal cylinder on the placement unit 2. During the winding process, the winding surface of the solid metal cylinder is in contact with the bonding member 53 and rotates synchronously with the placement unit 2. When the solid metal cylinder rotates in contact with the bonding member 53, it will push the bonding member 53 to drive the self-adaptive member 51 to slide back and forth in the left and right direction on the base 1. At the same time, the clamping member 31 moves synchronously with the bonding member 53, so as to smoothly wind the solid metal cylinder with film.
