However, because the film covering the side walls of the goods is not rolled, it cannot adhere well to the surface of the goods, resulting in gaps between the film and the surface. When the total area of the gaps is too large, the film is prone to moving on the goods, leading to poor packaging effect.
[0004] In view of this, this utility model is proposed. Utility Model Content

The protective shell is fixedly connected to the first mounting frame. The ring plate is symmetrically provided with second limiting rollers, and each second limiting roller is driven and connected to the transmission belt.
[0008] In a preferred embodiment of this utility model, each of the second limiting rollers meshes with the main gear, and the upper end of the main gear is symmetrically meshed with abutting gears. The abutting gears are rotatably connected to the ring plate, and a fixing block is fixedly connected to the inner wall of the ring plate. An installation roller is fixedly connected to the fixing block, and the installation roller is used to install the film cylinder.
[0009] In a preferred embodiment of this utility model, a connecting block is fixedly connected to one side of the fixed block, a sliding rod is slidably connected inside the connecting block, a movable frame is slidably connected to the end of the sliding rod, a spring is provided between the movable frame and the sliding rod, the ends of the springs are fixedly connected to the corresponding sliding rods and the movable frame respectively, and the abutment wheel is rotatably connected to the movable frame.
[0010] In a preferred embodiment of this utility model, the ring plate is composed of two identical plates, with a connecting column fixedly connected between the ring plates. A guide block is fixedly connected to the ring plate, and a guide groove is provided on the guide block. The end of the sliding rod is slidably connected to the guide groove.
[0011] In a preferred embodiment of the present invention, a bracket is fixedly connected to the first mounting frame, a side clamp is fixedly connected to the bracket, and a main clamp is mounted on the bracket via an electric slide rail.
[0012] In a preferred embodiment of the present invention, a second mounting bracket is symmetrically and fixedly connected to the first mounting bracket. A drive motor is fixedly connected to one side of the second mounting bracket, and a lead screw is fixedly connected to the output end of the drive motor.

The end of the first limiting roller is rotatably connected to the corresponding slider. One side of the slider is threadedly connected to the lead screw, and the other side of the slider is slidably connected to the optical axis guide rail.
[0014] Compared with the prior art, the present invention has the following advantages:
[0015] 1. This film wrapping device includes an installation roller that wraps the film around the wall of the goods. As the installation roller moves, it drives the abutment wheel to move and make full contact with the wall of the goods. During the wrapping process, the film is pressed to prevent excessive space between the film and the goods, which would result in poor packaging effect. In addition, the device uses the installation roller to wrap the film around the goods, stretching and wrapping the film around the goods. This avoids excessive gaps, which would make the film easily move on the goods and result in poor packaging effect.
[0016] 2. In this film wrapping device, the main clamping plate moves the excess film at the end of the goods, and clamps the excess film between the main clamping plate and the side clamping plate. After the goods are transported, the film is torn. In the next film wrapping, there is no need for manual covering of the film end on the goods. This device directly wraps the film, and the clamped film is wrapped inside the film during the wrapping process. At this time, the electric slide rail drives the main clamping plate to separate from the side clamping plate and release the clamping.
[0017] 3. In this film wrapping packaging device, the slider drives the first limiting roller to rise and fall to a suitable position. During the process of the first limiting roller contacting the wall of the goods, the goods are limited to prevent them from shifting in the packaging and affecting the packaging quality.

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0027] Please see Figure 1-5A film wrapping device includes a wrapping assembly for rapid and stable wrapping. The wrapping assembly includes a first mounting frame 1, conveyor belts 11, a servo motor 31, ring plates 4, main gears 42, mounting rollers 6, and abutment rollers 68. The conveyor belts 11 are symmetrically arranged on the first mounting frame 1, and each conveyor belt 11 is fixedly mounted to the first mounting frame 1. The servo motor 31 is fixedly connected to the first mounting frame 1. The ring plates 4 are located in the middle of the conveyor belts 11 and are fixedly connected in the middle. The main gears 42 are located between the ring plates 4 and are driven by the servo motor 31. The mounting rollers 6 are located on the main gears 42. The abutment rollers 68 are elastically arranged with the ring plates 4 to wrap the goods. The goods are placed on the conveyor belt 11. The conveyor belt 11 moves the goods between the ring plates 4. The servo motor 31 drives the main gear 42 to rotate through the output end. The main gear 42 drives the mounting roller 6 to rotate. The mounting roller 6 wraps the film around the wall of the goods. As the mounting roller 6 moves, it drives the abutment wheel 68 to move and make full contact with the wall of the goods. During the wrapping of the goods, the film is pressed to avoid the space between the film and the goods being too large, which would result in poor packaging effect. In addition, the method of wrapping the film around the goods by the mounting roller 6 in this device stretches and wraps the film around the goods, avoiding the film from easily moving on the goods when the total area of the gap is too large, resulting in poor packaging effect of the film.
[0028] The output end of the servo motor 31 is connected to a transmission belt 33. A second limiting roller 34 is symmetrically arranged on the wall of the transmission belt 33. A protective shell 32 is rotatably connected to the second limiting roller 34 and fixedly connected to the first mounting frame 1. Second limiting rollers 34 are symmetrically arranged on the ring plate 4. Each second limiting roller 34 is connected to the transmission belt 33 and meshes with a main gear 42. An abutment gear 41 is symmetrically meshed at the upper end of the main gear 42 and rotatably connected to the ring plate 4. A fixing block 63 is fixedly connected to the inner wall of the ring plate 4. An installation roller 6 is fixedly connected to the fixing block 63. The installation roller 6 is used to install the film cylinder. A connecting block 65 is fixedly connected to one side of the fixing block 63. A sliding rod 64 is slidably connected inside the connecting block 65. A movable frame 67 is slidably connected to the end of the sliding rod 64. A spring 66 is provided between the movable frame 67 and the sliding rod 64. The ends of the springs 66 are fixedly connected to the corresponding sliding rods 64 and movable frames 67 respectively. An abutment wheel 68 is rotatably connected to the movable frame 67. The ring plate 4 is composed of two identical plates. A connecting post 3 is fixedly connected between the ring plates 4. A guide block 61 is fixedly connected to the ring plate 4. A guide groove 62 is provided on the guide block 61. The end of the sliding rod 64 is slidably connected to the guide groove 62. The servo motor 31 drives the transmission belt 33 through its output end. The transmission belt 33 drives the second limit roller 34 to rotate. The transmission belt 33 is kept in place by the influence of the second limit roller 34 during transmission. In a taut state, the protective shell 32 protects components such as the conveyor belt 33 and the second limiting roller 34. The second limiting roller 34 is synchronized with the conveyor belt 33 and meshes with the main gear 42. During the rotation of the main gear 42, the abutting gear 41 meshes with it, allowing for free rotation. Through multiple meshing, power distribution is achieved during the rotation of the main gear 42, stabilizing its speed. The rotation of the main gear 42 also drives the corresponding fixed block 63 to move accordingly. The mounting roller 6 on the fixed block 63 follows the main gear 42 and rotates around the goods, wrapping the film around the goods' surface during the wrapping and stretching process, quickly completing the packaging operation. The stretching method straightens the film and brings it into close contact with the goods. As the fixing block 63 moves, it drives the connecting block 65, which in turn drives the sliding rod 64. The end of the sliding rod 64 slides in the guide groove 62 and is guided by the guide groove 62. The other end of the sliding rod 64 moves intermittently and squeezes the film to stretch it, improving the film's wrapping and covering efficiency. The sliding rod 64 also drives the end of the abutting wheel 68 to make intermittent contact with the wall of the goods. The abutting wheel 68 is pushed and compresses the spring 66, causing the spring 66 to deform and apply the deformation force to the abutting wheel 68. The abutting wheel 68 brings the film into close contact with the wall of the goods, avoiding gaps caused by the deformation characteristics of the film and the shape of the goods after wrapping.
[0029] The first mounting frame 1 is fixedly connected to a bracket 5, and a side clamping plate 52 is fixedly connected to the bracket 5. The bracket 5 is equipped with a main clamping plate 51 via an electric slide rail. After the winding is completed, the internal components of the electric slide rail drive the main clamping plate 51 to move toward the side clamping plate 52. During the movement, the main clamping plate 51 moves the excess film at the end of the goods, and clamps the excess film between the main clamping plate 51 and the side clamping plate 52. After the goods are transported, the film is torn. In the next packaging of the goods, there is no need for manual covering of the film end on the goods. This device directly winds the film. During the winding, the film simultaneously winds the clamped film inside. At this time, the electric slide rail drives the main clamping plate 51 to separate from the side clamping plate 52 and releases the clamping.
[0030] It is worth noting that the electric slide rail includes an outer frame, an inner frame, and a ball bearing structure. The ball bearing structure is located within the slide rails on both sides of the outer frame. The inner frame is slidably connected to the outer frame through cooperation with the ball bearing structure. An electric drive structure is located at the rear end of the inner side of the outer frame, and a transmission structure is connected to the front end of the electric drive structure. The inner frame is located above the transmission structure. The transmission structure includes a lead screw, which is located on the inner side of the outer frame along its length. A lead screw nut is located on the lead screw, and the lead screw nut is fixedly connected to the inner side of the inner frame. The electric drive structure is connected to the rear end of the lead screw, and the electric drive structure drives the lead screw nut to move linearly along the lead screw. This utility model places the drive motor inside the slide rail, making the internal structure of the slide rail more compact and saving a lot of space on the outside of the slide rail. Furthermore, this utility model makes the slide rail a miniature electric slide rail, resulting in a smaller overall structural size and greatly improving the utilization of the external space of the slide rail. The electric slide rail has been fully disclosed in the document CN202420203012.3, a miniaturized electric slide rail, and will not be repeated here.
[0031] The first mounting frame 1 is symmetrically and fixedly connected to a second mounting frame 2. A drive motor 21 is fixedly connected to one side of the second mounting frame 2, and a lead screw 22 is fixedly connected to the output end of the drive motor 21. The lead screw 22 is rotatably connected to the second mounting frame 2. An optical axis guide rail 23 is fixedly connected to the other side of the second mounting frame 2. Each second mounting frame 2 is provided with a first limiting roller 25. A slider 24 is symmetrically arranged on the first limiting roller 25, and the end of the first limiting roller 25 is rotatably connected to the corresponding slider 24. One side of the slider 24 is connected to the lead screw. The two sides are connected by threads, and the slider 24 on the other side is slidably connected to the optical axis guide rail 23. When the goods are transported on the conveyor belt 11, the drive motor 21 drives the lead screw 22 to rotate through the output end. The lead screw 22 drives the slider 24 on one side to rise and fall to a suitable position through thread transmission. The slider 24 on the other side rises and falls through the optical axis guide rail 23. The slider 24 drives the first limiting roller 25 to rise and fall to a suitable position. The first limiting roller 25 limits the goods during the process of contacting the wall of the goods, so as to prevent the goods from shifting in the packaging and affecting the packaging quality.
[0032] It is worth noting that the drive motor 21, servo motor 31 and other components are controlled by corresponding switches, and the corresponding switches are electrically connected to the drive motor 21, servo motor 31 and other components. Since switch control is an existing mature technology and is not an improvement of this optimization solution, it is not described in detail in the manual and will not be repeated here.
[0033] Working Principle: Goods are placed on conveyor belt 11. Conveyor belt 11 moves the goods between the ring plates 4. Servo motor 31 drives main gear 42 to rotate via its output end. The main gear 42 rotates, driving mounting roller 6. Mounting roller 6 wraps the film around the wall of the goods. As mounting roller 6 moves, it drives abutment roller 68 to move, ensuring full contact with the wall of the goods. During the wrapping process, the film is pressed to prevent excessive space between the film and the goods, which would result in poor packaging. Furthermore, this device uses mounting roller 6 to wrap the film around the goods, stretching and wrapping the film to prevent excessive gaps that could cause the film to move easily on the goods, leading to poor packaging. Servo motor 31... 1. The output end drives the conveyor belt 33, which in turn drives the second limiting roller 34 to rotate. During transmission, the conveyor belt 33 remains taut due to the influence of the second limiting roller 34. The protective shell 32 protects the conveyor belt 33, the second limiting roller 34, and other components. The second limiting roller 34 is synchronized under the transmission of the conveyor belt 33 and meshes with the main gear 42. During the meshing and rotation of the main gear 42, the abutment gear 41 meshes with the main gear 42 and rotates freely. Through multiple sets of meshing, power distribution is formed during the rotation of the main gear 42, making the speed of the main gear 42 more stable. During the rotation of the main gear 42, the corresponding fixed block 63 moves accordingly. The mounting roller 6 on the fixed block 63 follows the main gear 42 and moves with the fixed block 63. Block 63 rotates around the goods, wrapping the film around the goods' wall surface during the circumferential stretching process, quickly completing the packaging operation. The circumferential stretching method straightens the film and ensures tight contact with the goods. As the fixed block 63 moves, it drives the connecting block 65, which in turn drives the sliding rod 64. The end of the sliding rod 64 slides within the guide groove 62, guided by the groove. The other end of the sliding rod 64 moves intermittently, squeezing and stretching the film to improve the film's wrapping efficiency. The sliding rod 64 also causes the end of the abutment wheel 68 to intermittently contact the goods' wall surface. The abutment wheel 68 is pushed and compresses the spring 66, causing the spring 66 to deform and apply the deformation force to the abutment wheel 68. The abutment wheel 68 ensures tight contact between the film and the goods' wall surface, avoiding... To prevent gaps from forming after wrapping due to the deformation characteristics of the film and the shape of the goods, after wrapping, the internal components of the electric slide rail drive the main clamping plate 51 to move towards the side clamping plate 52. During this movement, the main clamping plate 51 moves the excess film at the end of the goods, clamping it between the main clamping plate 51 and the side clamping plate 52. After the goods are transported, the film is broken. In the next packaging, there is no need for manual covering of the film end with the goods; this device directly wraps the film, simultaneously encasing the clamped film within it. At this point, the electric slide rail separates the main clamping plate 51 from the side clamping plate 52, releasing the clamp. When the goods are transported on the conveyor belt 11, the drive motor 21 drives the lead screw 22 to rotate via its output end.The lead screw 22 drives one side slider 24 to rise and fall to a suitable position via threaded transmission. The other side slider 24 rises and falls via the optical axis guide rail 23. The slider 24 drives the first limiting roller 25 to rise and fall to a suitable position. The process of the first limiting roller 25 contacting the wall of the goods limits the goods and prevents them from shifting in the packaging, thus affecting the packaging quality.
