Technical Field

[0001] The utility model relates to the technical field of packaging, in particular to a film bundling device for a wrapping packaging machine. Background Art

[0002] Wrapping the goods with stretch film can not only provide a tight protective layer for the goods, effectively preventing them from being damaged by dust, moisture and mechanical damage during transportation, and ensuring that the goods arrive at the destination safely; at the same time, this layer of stretch film can also firmly fix the goods to prevent them from shifting or tipping over during transportation, thereby improving the overall stability of the goods. Therefore, it is particularly necessary to wrap the goods with stretch film. The existing wrapping packaging machine is an important tool to achieve this packaging process. It greatly improves packaging efficiency and reduces labor costs through automated operation, and ensures the uniformity and stability of packaging quality. For the modern logistics industry, the wrapping packaging machine is undoubtedly an indispensable and important equipment.

[0003] The existing wrapping packaging machine includes a lifting mechanism, on which a film frame is installed. The film frame is wrapped with a stretch film. It only needs to fix the movable end of the stretch film on the goods, rotate the goods, and control the lifting of the film frame through the lifting mechanism, so that the stretch film can be evenly wrapped on the goods, thereby achieving effective packaging of the goods.

[0004] In actual applications, since the stretch film is very thin, in order to ensure that the goods can be stably fixed, it is often necessary to control the film frame to rise and fall repeatedly through a lifting mechanism, so as to achieve multiple wrapping of the goods. However, this repeated wrapping operation mode will reduce the overall packaging efficiency. Summary of the invention

[0005] The utility model aims at solving the problem that in order to ensure the strength of the wrapping, the goods need to be wrapped multiple times, which will lead to a decrease in packaging efficiency. The utility model provides a film bundling device for a wrapping packaging machine which can ensure the strength of the wrapping without wrapping the goods multiple times and will not lead to a decrease in packaging efficiency.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is a film bundle device for a wrapping packaging machine, including a bracket, a roller is installed on the upper end of the bracket, the lower end of the bracket is fixedly connected to one side of the support plate, and the other side of the support plate is rotatably connected to the base. The base is fixed on the film frame of the wrapping packaging machine, and one side of the stretch film is squeezed by the roller, so that the overall width of the stretch film is reduced, and the thickness of the squeezed side of the stretch film is increased. This reduces the number of wrapping times, and even only a single wrapping is required, which significantly improves the packaging efficiency. At the same time, the stretch film will form wrinkles on the side squeezed by the roller. These wrinkles can generate bubbles during the wrapping process, providing an additional buffer layer for the goods, improving the safety of the goods during transportation and storage, and providing better protection for the goods.

[0007] Preferably, a mounting frame is provided at the upper end of the bracket, the mounting frame is in a "concave" shape, and the mounting frame includes a bottom plate and two parallel side plates, the lower surface of the bottom plate is fixedly connected to the upper end of the bracket, the two side plates are provided with mounting holes, and the center lines of the two mounting holes coincide, and a mounting shaft passing through the two mounting holes is provided between the two side plates, and the roller is sleeved on the mounting shaft. The roller can flexibly rotate around the mounting shaft to ensure that the stretch film passes smoothly.

[0008] Preferably, an annular groove is provided on the outer wall of the roller, and the annular groove is located in the middle of the roller. The annular groove can more effectively restrain the stretch film and prevent it from slipping during the rotation of the roller, thereby ensuring the accuracy and stability of the packaging.

[0009] Preferably, a screw hole is provided on the side of the support plate close to the bracket, and a locking hole is provided at the lower end of the bracket, the size of the locking hole is adapted to the screw hole, and a bolt is installed in the locking hole. The bracket can be firmly fixed on the support plate by passing the bolt through the locking hole and screwing it into the screw hole.

[0010] Preferably, the locking hole is a long slotted hole, and the length direction of the long slotted hole is parallel to the vertical direction. By adjusting the position of the bolt in the locking hole, the height of the roller can be easily adjusted, thereby achieving accurate control of the width of the stretch film.

[0011] Preferably, a fixed shaft is fixed on the base, the upper end of the fixed shaft is fixedly connected to the bottom of the base, the lower end of the fixed shaft is rotatably connected to the support plate, and a thread is arranged on the outer circumferential surface of the lower end of the fixed shaft. The support plate is flexibly rotatably connected to the base through the fixed shaft, ensuring that the roller can move according to the movement of the stretch film.

[0012] Preferably, a groove is provided on the upper surface of the support plate away from the bracket, and a connection hole is provided at the bottom of the groove, the size of the connection hole is adapted to the lower end of the fixed shaft, and the lower end of the fixed shaft passes through the connection hole and is fixed with a nut. The nut is tightly matched with the thread at the lower end of the fixed shaft, and the support plate is stably restricted between the nut and the base, so that the support plate can rotate smoothly around the axis of the fixed shaft.

[0013] Preferably, a bearing is installed in the groove, the outer ring of the bearing is fixedly connected to the inner wall of the groove, and the inner ring of the bearing is fixedly connected to the outer wall of the fixed shaft. The bearing ensures that the support plate can achieve stable and smooth rotation.

[0014] It can be seen from the above technical solutions that the advantages of the utility model are: the base is installed on the film frame of the wrapping packaging machine, and one side of the stretch film is squeezed by the roller, which effectively reduces the overall width of the stretch film and increases the thickness of the squeezed side. By fine-tuning the position of the bolt in the locking hole, the height of the roller can be easily and accurately adjusted, thereby accurately controlling the width of the stretch film. In summary, the device significantly reduces the number of wrappings, and even enables packaging to be completed with a single wrapping, greatly improving packaging efficiency. In addition, the wrinkles formed by the roller extrusion produce bubbles during the wrapping process, providing an additional buffer layer for the goods, effectively enhancing the safety of the goods during transportation and storage, and providing more comprehensive protection for the goods.

[0025] like Figure 1-3 As shown, in this specific embodiment, the base 1 specifically adopts the following structure: the base 1 adopts a rectangular plate, and a fixed shaft 13 is arranged below the base 1. The fixed shaft 13 is a stepped shaft, and the upper end of the fixed shaft 13 is an end with a larger diameter, and the lower end of the fixed shaft 13 is an end with a smaller diameter. The upper end of the fixed shaft 13 is fixed to the lower surface of the base 1 by welding, and a thread 131 is arranged on the outer circumferential surface of the lower end of the fixed shaft 13.

[0026] like Figure 4 As shown, a countersunk hole 12 is provided on the lower surface of the base 1, and a countersunk screw 11 is installed in the countersunk hole 12. In this embodiment, two countersunk holes 12 and two countersunk screws 11 are provided, and the two countersunk holes 12 are distributed on both sides of the fixed shaft 13, and the positions and sizes of the two countersunk holes 12 are adapted to the holes on the film frame 6. The countersunk screw 11 is inserted through the countersunk hole 12 and into the hole on the film frame 6, so that the base 1 can be fixed on the film frame 6.

[0027] In this specific embodiment, the support plate 2 specifically adopts the following structure: a groove 21 is provided on the upper surface of the support plate 2 near the base 1, the groove 21 is circular, and the groove 21 does not penetrate the support plate 2. A connecting hole is provided at the middle position of the bottom of the groove 21, the connecting hole penetrates the entire support plate 2, and the size of the connecting hole is adapted to the lower end of the fixed shaft 13. The lower end of the fixed shaft 13 is passed through the connecting hole and a nut is installed, so that the support plate 2 can be stably restricted between the nut and the base 1.

[0028] A bearing 22 is installed in the groove 21, and the outer ring of the bearing 22 is fixedly connected to the inner wall of the groove 21 by interference fit, and the inner ring of the bearing 22 is fixedly connected to the outer wall of the fixed shaft 13 by interference fit. A retaining ring 1 is installed above the bearing 22, and the retaining ring is sleeved on the fixed shaft 13. The outer diameter of the retaining ring 1 is the same as the diameter of the groove 21, and the inner diameter of the retaining ring 1 is the same as the diameter of the lower end of the fixed shaft 13, that is, the top of the retaining ring 1 abuts against the upper end of the fixed shaft 13, and the bottom of the retaining ring 1 abuts against the bearing 22. The retaining ring 1 can press the bearing 22 to prevent the bearing 22 from escaping from the groove 21.

[0029] The side of the support plate 2 away from the base 1 is provided with screw holes, and the screw holes are used to be fixedly connected with the bracket 3. In this embodiment, there are two screw holes, and the two screw holes are symmetrically distributed along the middle position of the support plate 2.

[0030] In this specific embodiment, the bracket 3 specifically adopts the following structure: the bracket 3 is placed vertically, and a locking hole 31 is provided at the lower end of the bracket 3, and the size of the locking hole 31 is adapted to the screw hole. In this embodiment, the locking hole 31 is a long slot hole, and the length direction of the long slot hole is parallel to the vertical direction. There are two locking holes 31, and the positions of the two locking holes 31 match the positions of the two screw holes respectively, and bolts are installed in the two locking holes 31. The bolts are passed through the locking holes 31 and screwed into the screw holes, so that the bracket 3 can be firmly fixed on the support plate 2. By adjusting the position of the bolt in the locking hole 31, the height of the bracket 3 can be adjusted.

[0031] In this specific embodiment, the mounting frame 4 specifically adopts the following structure: the mounting frame 4 is in a "concave" shape, and the mounting frame 4 includes a base plate and two mutually parallel side plates, the base plate and the two mutually parallel side plates are connected by welding, and the lower surface of the base plate is connected to the upper end of the bracket 3 by welding.

[0032] The two side plates are provided with mounting holes, and the center lines of the two mounting holes coincide. A mounting shaft 41 is provided between the two side plates and passes through the two mounting holes. The two ends of the mounting shaft 41 are sleeved with a second retaining ring 42, and the second retaining ring 42 can fix the mounting shaft 41 on the mounting frame 4.

[0033] The roller 5 is sleeved in the middle of the mounting shaft 41, and the roller 5 can rotate around the axis of the mounting shaft 41. An annular groove 51 is provided on the outer wall of the roller 5, and the annular groove 51 is a "V" shape with high sides and low middle, and the annular groove 51 is located in the middle of the roller 5.

[0034] The specific use process of the utility model is as follows: Figure 5 As shown, first, the base 1 is fixed on the film frame 6 of the wrapping machine, and the position of the bolt in the locking hole 31 is accurately adjusted and tightened. Next, the movable end of the stretch film 7 on the film frame 6 is fixed on the goods. At this time, the stretch film 7 is placed vertically, and the lower side of the stretch film 7 is stuck in the annular groove 51 of the roller 5. The roller 5 applies an upward squeezing force to the lower side of the stretch film 7, so that the lower side of the stretch film 7 is thickened and the overall width of the stretch film 7 is narrowed.

[0035] After the wrapping machine is started, the film frame 6 starts to move upward, and the turntable under the goods rotates synchronously. During this process, since the upper side of the stretch film 7 is thinner and the lower side is thicker, the thick part naturally covers the thin part during wrapping, and a single wrapping can achieve a thicker and stronger packaging effect, thereby improving packaging efficiency.

[0036] It can be seen from the above embodiments that the beneficial effect of the utility model is that the base is installed on the film frame of the wrapping packaging machine, and one side of the stretch film is squeezed by the roller, which effectively reduces the overall width of the stretch film and increases the thickness of the squeezed side. By fine-tuning the position of the bolt in the locking hole, the height of the roller can be easily and accurately adjusted, thereby accurately controlling the width of the stretch film. In summary, the device significantly reduces the number of windings, and even enables packaging to be completed with a single winding, greatly improving packaging efficiency. In addition, the wrinkles formed by the roller extrusion generate bubbles during the winding process, providing an additional buffer layer for the goods, effectively enhancing the safety of the goods during transportation and storage, and providing more comprehensive protection for the goods.

[0037] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
