[0016] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0017] like Figure 1-8The figure shows an embodiment of the present invention. To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a crawler pin shaft efficient automatic packaging device, comprising a packaging rack 1 installed on a workbench, a conveying platform 11 for conveying products is arranged on both the front and rear sides of the packaging rack 1, a pin shaft 4 is placed on the conveying platform 11, and two positioning mechanisms 111 for positioning the pin shaft 4 to the center position are arranged on each conveying platform 11, a gear ring 2 is arranged in the gap of the packaging rack 1, and four gears 2 are meshed equidistantly on the outer edge of the gear ring 2 1, and a film roll 22 is fixedly installed on the front surface of the gear ring 2 for placing the film roll. The film roll 22 can be fixedly installed at any position on the gear ring 2 by bolts. When the gear ring 2 rotates, the film roll 22 rotates accordingly. When the pin shaft 4 is transmitted to the center position of the hollow part of the front surface of the packaging rack 1 through the transmission platform 11, the gear ring 2 starts to drive the film roll 22 to wrap the film around the pin shaft 4. The wrapping process continues until the pin shaft 4 is transmitted from the transmission platform 11 on the rear side of the packaging rack 1 to the transmission platform 11 on the front side; Among them, the conveying roller of the conveying platform 11 located at the rear side of the packaging rack 1 is close to the rear side wall of the packaging rack 1, such as Figure 4 and Figure 6 As shown, the positioning mechanism 111 includes a positioning frame installed on the conveying platform 11 and a plurality of rollers installed and vertically distributed on the positioning frame. A moving groove is opened on the connecting surface of the positioning frame and the conveying platform 11, and the positioning groove is penetrated by bolts to be connected to the conveying platform 11. The plurality of rollers are of the same size and are rotatably connected to the positioning frame. The spacing between the two symmetrical positioning mechanisms 111 is adjusted according to the size of the pin shaft 4. During the adjustment: first, the bolts that penetrate the moving groove and the conveying platform 11 at the same time are screwed out, and the two positioning mechanisms 111 are relatively moved at the same time, so that the moving distances of the two positioning mechanisms 111 are equal, so that the pin shaft 4 can be positioned to the center position. After adjusting the distance, the bolts are re-penetrated and connected to the moving groove and the conveying platform 11. After the pin shaft 4 is placed on the conveying platform 11, the two side surfaces of the pin shaft 4 are respectively in active contact with the plurality of rollers of the two symmetrical position positioning mechanisms 111. During the forward movement of the pin shaft 4, the plurality of rollers rotate accordingly, which helps to reduce the contact friction between the pin shaft 4 and avoid resistance to the movement of the pin shaft 4, and at the same time, avoid wear on the surface of the pin shaft 4.

[0018] Furthermore, a film-drawing assembly 3 is provided at the front side of the packaging rack 1 for drawing and cutting the film on the film roll 22. The film-drawing assembly 3 includes an upper film plate 31 and a lower film plate 32 which are integrally connected. A movable cutter 321 is provided inside the lower film plate 32. Cylinders 33 are installed on the two facing outer sides of the upper film plate 31 and the lower film plate 32. A film-pressing plate 311 connected to the output shaft of the cylinder 33 on the outer side of the upper film plate 31 is provided between the upper film plate 31 and the lower film plate 32 for clamping the film. The width of the film-pressing plate 311 is the same as that of the upper film plate 31 and the lower film plate 32, and the film-pressing plate 311 is parallel to the upper film plate 31 and the lower film plate 32 respectively. When clamping the film, the film-pressing plate 311 is driven to move by the cylinder 33 located on the outer side of the upper film plate 31 until the film is clamped between the film-pressing plate 311 and the lower film plate 32. The thickness of the lower membrane plate 32 is greater than the thickness of the upper membrane plate 31. Figure 3 As shown, a plurality of vertical grooves are provided on the surface of the lower membrane plate 32 on one side opposite to the upper membrane plate 31. The provision of the plurality of grooves can increase the contact friction between the lower membrane plate 32 and the membrane, making it difficult for the membrane to slip during clamping and having higher stability.

[0019] Furthermore, a cutter 321 connected to the output shaft of the cylinder 33 on its outer side is provided inside the lower film plate 32 for cutting the film. The upper film plate 31 and the lower film plate 32 are connected to form a "U"-shaped structure. The opening of the "U"-shaped structure faces the hollow position of the packaging frame 1. The horizontal position of the film pulling assembly 3 is between the film roll 22 and the pin 4. When the pin 4 is wrapped with the film, the film roll 22 is at the highest point of the hollow part of the packaging frame 1. Figure 6 As shown, at this time, the opening of the "U"-shaped structure of the film-pulling assembly 3 is facing the front side of the film on the pin shaft 4 and the film roll 22. At this time, the film-pulling assembly 3 is moved to the opening of its "U"-shaped structure to clamp the film, and then the cylinder 1 33 located on the upper film plate 31 is started to clamp the film, and then the cylinder 1 33 located on the lower film plate 32 is started to cut the film; Among them, Figure 7 As shown, a cutting knife groove which vertically penetrates all the grooves is horizontally opened on the surface of the side of the lower film plate 32 opposite to the upper film plate 31, and the cutting knife 321 is located inside the cutting knife groove. When the cutting knife 321 is not used, the cutting knife 321 is connected and driven by the film roll 22 outside the lower film plate 32 and is completely embedded in the cutting knife groove. When the cutting knife 321 is used to cut the film, the cylinder 33 therein drives the cutting knife 321 to move out of the cutting knife groove and cut the film. Among them, the cutting groove divides the side of the lower film plate 32 into a clamping surface and a cutting surface with the same upper and lower cross-sectional areas. The clamping surface is located above the cutting groove and is flush with the side of the lower film plate 32, and the cutting surface is located below the cutting groove and is recessed compared to the side of the lower film plate 32. Therefore, when the film pressing plate 311 and the lower film plate 32 are clamped, the film pressing plate 311 only fits with the clamping surface of the lower film plate 32, and there is a gap between the cutting surface of the lower film plate 32. When the cutter 321 cuts the film, the film on the film roll 22 is still clamped by the film pulling assembly 3, and the film wrapped on the pin 4 falls off downward, which is convenient for automatic packaging of subsequent products.

[0020] Further, such as Figure 8 As shown, the hollow part of the packaging rack 1 is circular and its diameter is larger than the inner diameter of the gear ring 2. The film roller 22 is vertically fixed to the outer surface of the gear ring 2 by bolts. The distance between the conveying roller of the conveying platform 11 on the front side of the packaging rack 1 and the front surface of the packaging rack 1 is larger than the length of the film roller 22. The diameter of the gear ring 2 is larger than the diameter of the gear 21. The four gears 21 are of the same size and are respectively installed on the inner wall of the gap of the packaging rack 1 through a rotating shaft. Gaps are provided between the front and rear sides of the gear ring 2 and the inner wall of the gap of the packaging rack 1. Any gear 21 can be connected to a servo motor through a shaft. According to the actual installation position of the equipment, a servo motor can be selected to be connected to a gear 21 at a suitable position. The servo motor drives the gear 21 to rotate and further drives the gear ring 2 to rotate. The process of rotation of the gear ring 2 drives the film roller 22 to roll the film.

[0021] Further, such as Figure 5 and Figure 6 As shown, a holder 5 is installed on one side surface of the packaging rack 1 by bolts, a slide rail 51 is fixedly connected to the holder 5, a cylinder 52 is slidably connected to the slide rail 51, the output shaft of the cylinder 52 is fixedly connected to the holder 5 by bolts, the outer surface of the cylinder 52 is fixedly connected to a support plate 53 arranged parallel to the packaging rack 1 by bolts, the film pulling component 3 is fixedly connected to the support plate 53 by bolts, the film pulling component 3 is arranged parallel to the cylinder 52, and one end of the output shaft of the cylinder 52 is fixedly connected to the holder 5 by bolts. The film pulling component 3 and the cylinder 52 are arranged parallel to each other. Since one end of the output shaft of the cylinder 52 is fixed to the holder 5, after the holder 5 is started, its output end can move in and out from the inside to drive the cylinder 52 to move on the slide rail 51. During the movement of the cylinder 52, the film pulling component 3 is driven to move synchronously through the support plate 53, and the moving trajectory of the film pulling component 3 is a horizontal displacement forward and backward along a fixed height, so that the opening of the "U"-shaped structure of the film pulling component 3 is inserted in and removed from the side of the film.

[0022] When the above embodiment is working, in the initial state: the film drawing assembly 3 is located at the front side of the film rolling roller 22, and the film rolling roller 22 will not touch the film drawing assembly 3 when rotating, there is a certain gap between the film pressing plate 311 and the lower film plate 32 to facilitate the insertion of the film, and the cutter 321 is completely embedded in the cutter groove, and the film rolling roller 22 is located at the highest point of the hollow part of the packaging frame 1. At this time, the end of the film on the film rolling roller 22 naturally droops to a horizontal position lower than the film drawing assembly 3; Before the roll film packaging of the pin shaft 4 is carried out: the pin shaft 4 is clamped and positioned by the positioning mechanism 111 and the pin shaft 4 is conveyed forward by the conveying platform 11, and the cylinder 2 52 is started to retract its output shaft. At this time, the cylinder 2 52 moves toward the direction of the clamping seat 5. When the cylinder 2 52 moves, it drives the film-drawing assembly 3 to move synchronously through the support plate 53 until the film-drawing assembly 3 is moved to the opening of its "U"-shaped structure and clamped from the side of the film. Then, the cylinder 1 33 located on the upper film plate 31 is started to drive the film pressing plate 311 to clamp the film, and then the film-drawing assembly 3 is returned to its original position by the drive of the cylinder 2 52; When the pin 4 is being wrapped with film: when the pin 4 moves to a point where its front end is close to the front surface of the packaging frame 1, the servo motor connected to the gear 21 is started, and the servo motor drives the gear 21 to rotate and further drives the gear ring 2 to rotate. The rotation of the gear ring 2 drives the film roll 22 to rotate and wrap the film around the pin 4. After the film on the pin 4 is wrapped 1-2 times, the film pressing plate 311 returns to its original state to loosen the film. The wrapping process continues until the pin 4 is completely wrapped with the film. After the pin 4 is wrapped, the air is started again. The cylinder 2 52 drives the opening of the "U"-shaped structure of the film-pulling assembly 3 to be clamped again from the side of the film, and the film is re-clamped. Then the cylinder 1 33 on the lower film plate 32 is started to drive the cutter 321 to move out of the cutter groove and cut the film. At this time, the film on the film roll 22 is still clamped by the film-pulling assembly 3, and the film wrapped on the pin 4 falls off downward, completing the film roll packaging of the pin 4. The above steps can be repeated when packaging the next pin 4. Continuous automation can be carried out, and the packaging process completely replaces manual labor, which helps to improve packaging efficiency.
