Description

Technical Field

[0001] This utility model relates to the field of stretch wrap packaging technology, and in particular to a tie rope structure for stretch wrap. Background Technology

[0002] A stretch film packaging machine is a device that uses a motor-driven sprocket to compress stretch film or other materials into different widths or a single strand of rope via pressure rollers. It can be configured according to customer requirements to help users accurately pack each box.

[0003] The existing tie-rope structure for stretch wrap film cannot be arbitrarily narrowed to a specified height; it must be tied into a single rope at the very least, which increases working time, reduces work efficiency and packaging effect, and is inconvenient for subsequent packaging and handling. Therefore, there is an urgent need to design a tie-rope structure for stretch wrap film to solve the above problems. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution: a tie rope structure for stretch wrapping film, comprising a fixing frame, a positioning frame, and a wrapping film roller. A motor is detachably mounted on the top of the fixing frame, and a drive sprocket is fixedly mounted on the output shaft of the motor. A positioning hole is provided at the lower end of the fixing frame, and a rotating shaft is detachably mounted inside the positioning hole. A driven sprocket is movably mounted on the upper side of the rotating shaft. A chain is meshed with the outer sides of the drive sprocket and the driven sprocket. A fixing seat is fixedly mounted on the upper side of the fixing frame, and a film pressing wheel frame is fixedly mounted on the fixing seat. A film pressing wheel body is movably mounted on the inner side of the film pressing wheel frame.

[0005] As an improvement to the above technical solution, a positioning frame is detachably installed on the upper side of the fixing frame, and a winding film roller is movably installed on the upper side of the positioning frame.

[0006] As an improvement to the above technical solution, the rotating shaft extends to the rear side of the fixed frame, the rotating shaft passes through the positioning hole, and a limiting piece can be detachably installed on the rear side of the rotating shaft.

[0007] As an improvement to the above technical solution, an L-shaped positioning block is detachably installed on the upper side of the fixing frame, and a photoelectric monitor is detachably installed on the upper side of the L-shaped positioning block.

[0008] As an improvement to the above technical solution, positioning screws are evenly installed on the upper side of the pressing wheel frame, and the fixing seat and the pressing wheel frame are positioned by the positioning screws.

[0009] As an improvement to the above technical solution, a rotating rod is movably mounted on the upper side of the motor, and a monitoring gear is detachably mounted on the upper side of the rotating rod.

[0010] As an improvement to the above technical solution, a fixing block is fixedly installed on the upper side of the fixing frame, a fixing bracket is detachably installed on the upper side of the fixing block, and a positioning bolt is detachably installed on the upper side of the fixing bracket. The fixing block and the fixing bracket are positioned using the positioning bolt.

[0011] The beneficial effects of this utility model are:

[0012] The inclusion of a motor and drive sprocket facilitates the use of the stretch film binding mechanism after inspection. A chain mounted on the outside of the rotating shaft drives the driven sprocket at the bottom to rotate. Using a fixed base, pressure roller frame, and pressure roller body, the film is bound into a single rope, effectively reinforcing the packaging with a rope-like structure. This allows the stretch film to provide both thin-film covering and rope-reinforced packaging, ensuring a stable shape. It effectively binds and compresses stretch film of different sizes, significantly improving the film's compactness. When compressing short-length stretch film, it effectively prevents loosening, thus improving the overall forming effect of the stretch film.

[0013] The positioning frame, which is positioned by screws, is used to position the winding film roller.

[0014] The positioning hole is set on the upper side of the fixed frame. The rotating shaft passes through the positioning hole, which facilitates the movement of the rotating shaft. At the same time, the limiting piece can effectively position the rotating shaft.

[0015] An L-shaped positioning block is installed, and the L-shaped positioning block and the fixing frame are positioned using screws, which facilitates the installation of the photoelectric monitor. The photoelectric monitor can detect the position reached by the pressing wheel.

[0016] Using a positioning screw made of cast iron, the positioning screw can position the fixing seat and the pressure roller frame.

[0017] Using a rotating rod, the motor is started, which drives the rotating rod to rotate. This allows the monitoring gear to rotate, and the monitoring gear, together with the photoelectric sensor, can detect the number of rotations of the motor. This allows the motor to control the height of the film-taking wheel, achieving film output of different widths and completing the operation.

[0018] Using fixing blocks and fixing brackets, the membrane frame can be easily supported and the membrane can be placed. Using positioning bolts, the fixing blocks and fixing brackets can be positioned and installed, and the fixing brackets can be easily removed from the fixing blocks, reducing the operator's labor.

It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution for a tie rope structure for stretch wrapping film: A tie rope structure for stretch wrapping film includes a fixed frame 1, a positioning frame 2, and a wrapping film roller 3. A motor 4 is detachably installed on the top of the fixed frame 1. A drive sprocket 6 is fixedly installed on the output shaft of the motor 4. A positioning hole 7 is opened at the lower end of the fixed frame 1. A rotating shaft 8 is detachably installed inside the positioning hole 7. A driven sprocket 9 is movably installed on the upper side of the rotating shaft 8. A chain 10 is meshed with the outer sides of the drive sprocket 6 and the driven sprocket 9. A fixed seat 14 is fixedly installed on the upper side of the fixed frame 1. A pressure roller frame 15 is fixedly installed on the fixed seat 14. A pressure roller body 16 is movably installed on the inner side of the pressure roller frame 15.

[0027] In this embodiment, the motor 4 and the drive sprocket 6 are provided to facilitate the use of the wrapping film binding mechanism after inspection. The chain 10 installed on the outside of the rotating shaft 8 drives the driven sprocket 9 at the bottom to rotate. Using the fixed seat 14, the film pressing wheel frame 15 and the film pressing wheel body 16, the film can be bound into a rope, which is equivalent to the reinforcement packaging by rope binding. This allows the wrapping film to have both thin film covering packaging and rope binding reinforcement packaging, making it stable and effective for binding and compressing wrapping films of different sizes. It can effectively improve the compactness of the wrapping film, thereby effectively preventing the wrapping film from becoming loose when compressing small-sized and long wrapping films, thus improving the forming effect of the wrapping film.

[0028] Specifically, a positioning frame 2 is detachably installed on the upper side of the fixing frame 1, and a wrapping film roller 3 is movably installed on the upper side of the positioning frame 2.

[0029] In this embodiment, the positioning frame 2 is used, and the positioning frame 2 and the fixing frame 1 are positioned by screws, which can play a positioning role for the winding film roller 3.

[0030] As an improvement to the above technical solution, the rotating shaft 8 extends to the rear side of the fixed frame 1, the rotating shaft 8 passes through the positioning hole 7, and the limiting piece 11 can be detachably installed on the rear side of the rotating shaft 8.

[0031] In this embodiment, a positioning hole 7 is provided on the upper side of the fixed frame 1, through which the rotating shaft 8 passes, which facilitates the movement of the rotating shaft 8. At the same time, the limiting piece 11 can effectively position the rotating shaft 8.

[0032] As an improvement to the above technical solution, an L-shaped positioning block 12 is detachably installed on the upper side of the fixing frame 1, and a photoelectric monitor 13 is detachably installed on the upper side of the L-shaped positioning block 12.

[0033] In this embodiment, an L-shaped positioning block 12 is provided. The L-shaped positioning block 12 and the fixing frame 1 are positioned by screws, which facilitates the installation of the photoelectric monitor 13. The photoelectric monitor 13 can detect the position reached by the pressing wheel.

[0034] As an improvement to the above technical solution, positioning screws 17 are evenly installed on the upper side of the pressing wheel frame 15, and the fixing seat 14 and the pressing wheel frame 15 are positioned by the positioning screws 17.

[0035] In this embodiment, a positioning screw 17 is used. The positioning screw 17 is made of cast iron and can position the fixing seat 14 and the pressure roller frame 15.

[0036] As an improvement to the above technical solution, a rotating rod 18 is movably mounted on the upper side of the motor 4, and a monitoring gear 19 is detachably mounted on the upper side of the rotating rod 18.

[0037] In this embodiment, the rotating rod 18 is used to start the motor 4, which drives the rotating rod 18 to rotate. This allows the monitoring gear 19 to rotate easily. The monitoring gear 19, together with the photoelectric sensor, can detect the number of rotations of the motor 4. This allows the motor 4 to control the height of the film-taking wheel, thereby achieving film output of different widths and completing the operation.

[0038] As an improvement to the above technical solution, a fixing block 20 is fixedly installed on the upper side of the fixing frame 1, a fixing bracket 21 is detachably installed on the upper side of the fixing block 20, and a positioning bolt 22 is detachably installed on the upper side of the fixing bracket 21. The fixing block 20 and the fixing bracket 21 are positioned by the positioning bolt 22.

[0039] In this embodiment, the fixing block 20 and the fixing bracket 21 can be used to easily support the fixed membrane frame and place the membrane. The fixing block 20 and the fixing bracket 21 can be positioned and installed using the positioning bolt 22, making it easy to remove the fixing bracket 21 from above the fixing block 20 and reducing the operator's labor.

[0040] When using the device, first inspect the entire device. After inspection, place the device in the designated position. Then, when turning it on, start the motor 4. The motor 4 drives the drive sprocket 6 to rotate. At the same time, with the cooperation of the driven sprocket 9 installed on the upper side of the rotating shaft 8, the chain 10 can be rotated. Goods with a height of less than 500mm can be packaged at any height because it can automatically sense the height of the goods and automatically change the height of the film. After the film is narrowed, it automatically adapts to different heights of the goods. Using the fixed seat 14, the film pressing wheel frame 15 and the film pressing wheel body 16, the film can be tied into a rope, which is equivalent to the reinforcement packaging of the rope method. This allows the stretch film to have both thin film covering packaging and rope reinforcement packaging, with a stable shape. It can effectively bundle and compress stretch films of different sizes, effectively improving the compactness of the stretch film. Therefore, when compressing small-sized stretch films, it can effectively prevent the stretch film from becoming loose and improve the forming effect of the stretch film.

[0041] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
