Description

Technical Field

[0001] This utility model belongs to the technical field of film shrinking equipment, specifically relating to an automatic film shrinking machine for welding wire reels. Background Technology

[0002] Existing automatic shrink wrapping machines for welding wire spools typically consist of a feeding mechanism, a wrapping mechanism, a heat shrink chamber, a discharge mechanism, and a control system. The workflow is roughly as follows: the feeding mechanism transports the welding wire spool to be packaged to the wrapping station; the wrapping mechanism wraps the spool with heat shrink film; the wrapped spool is then sent into the heat shrink chamber, where a high-temperature environment is generated by heating elements (such as electric heating tubes or hot air circulation systems), causing the heat shrink film to shrink and tightly adhere to the surface of the welding wire spool; finally, the packaged spool is transported to a designated location by the discharge mechanism.

[0003] To ensure stable transport of the welding wire spool within the heat shrink chamber, existing technologies typically employ a roller conveyor assembly. The welding wire spool is placed on the rollers, and the rotation of the rollers drives the spool to move along the transport direction while simultaneously receiving high-temperature heating within the heat shrink chamber. When the welding wire spool is placed on the rollers, its bottom is in direct contact with the roller surface. The heat shrink film in the contact area is blocked by the rollers and cannot directly receive heat radiation or hot air, resulting in insufficient shrinkage and unevenness of the film in that area, making it prone to wrinkles and loosening. Utility Model Content

[0004] The purpose of this invention is to provide an automatic wire spool shrink wrapping machine, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic wire spool shrink wrapping machine includes an intermittent lifting assembly, which includes an external gear ring. A drive assembly for driving the external gear ring to rotate is located on the rear side of the external gear ring. The drive assembly is located in the equipment assembly. An auxiliary turbulence assembly includes multiple turbulence fan blades. Multiple protruding short striking shafts are fixedly connected to the front end of the external gear ring. The multiple protruding short striking shafts are arranged in a ring at equal intervals. A linkage rotation assembly for improving the turbulence intensity is provided in the multiple turbulence fan blades.

[0006] As a preferred embodiment of this utility model, the drive assembly includes a fixed bracket, with a bottom-opening ring-shaped guide rail fixedly connected to the upper end of the fixed bracket, and motors symmetrically fixedly connected to the left and right sides of the front end of the fixed bracket.

[0007] As a preferred embodiment of this utility model, a transmission gear ring is installed at the output end of the motor, and the two transmission gear rings are meshed with the external gear ring.

[0008] As a preferred embodiment of this utility model, the equipment components include a heating chamber, a roller-type electric conveyor belt installed on the lower inner wall of the heating chamber, and flexible baffles symmetrically fixedly connected to the front and rear ends of the heating chamber, with the two flexible baffles located at the inlet and outlet of the heating chamber respectively.

[0009] As a preferred embodiment of this utility model, the upper end of the roller-type electric conveyor belt is equipped with multiple sets of discs to be processed, and two fixed brackets are respectively fixedly connected to the left and right inner walls of the heating chamber.

[0010] As a preferred embodiment of this utility model, the linkage rotation assembly includes two side inner supports, which are respectively fixedly connected to the left and right inner walls of the heating chamber. A pair of transverse rotating shafts are mounted on the side inner supports near the outer gear ring. The two transverse rotating shafts are arranged vertically between each other. Multiple turbulence fan blades are sequentially fixedly connected to the end of the transverse rotating shafts near the outer gear ring, and the upper and lower multiple turbulence fan blades are staggered.

[0011] As a preferred embodiment of this utility model, a vertical spring is fixedly connected between two staggered turbulence fan blades, and a counter-rotating gear is fixedly connected to the middle of the horizontal rotating shaft. The two counter-rotating gears are meshed together, and the protruding striking short shafts are in intermittent contact with the nearest turbulence fan blades.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. In this solution, the workpiece is moved to the lifting assembly by the roller-type electric conveyor belt. The center hole is aligned with the end of the outer gear ring. The motor drives the transmission gear ring to rotate, and through meshing, drives the outer gear ring to rotate, so that the center hole of the workpiece is fitted into it. After the outer gear ring has rotated one full revolution, the workpiece falls back onto the conveyor belt through its opening. During this process, the workpiece is briefly lifted to separate it from the contact part of the conveyor belt, ensuring that all areas of the surface are heated evenly and ensuring that the shrinkage effect of the film is consistent.

[0013] 2. When the external gear ring rotates, the protruding short shaft at the front end also makes a circular motion. When it rotates to the position of the turbulence component, it intermittently pushes the adjacent turbulence fan blades to swing. The vertical horizontal rotating shaft is meshed through the opposing linkage gear. When the upper one rotates, it drives the lower one to rotate in the opposite direction, so that the staggered turbulence fan blades form a reverse turbulence. With the help of the vertical spring, it can buffer the impact and assist in the reset, improve the turbulence intensity, and ensure that the heat in the heating chamber is evenly applied to the disc wheel to be processed.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Example 1 Reference Figure 1-4 This is the first embodiment of the present invention. This embodiment provides an automatic wire spool shrinking machine, including an intermittent lifting assembly, which includes an outer gear ring 10. A drive assembly 11 for driving the outer gear ring 10 to rotate is provided on the rear side of the outer gear ring 10. The drive assembly 11 is located in the equipment assembly 12. An auxiliary turbulence assembly includes multiple turbulence fan blades 20. Multiple protruding striking short shafts 21 are fixedly connected to the front end of the outer gear ring 10. The multiple protruding striking short shafts 21 are arranged in a ring at equal intervals. A linkage rotation assembly 22 for improving the turbulence intensity is provided in the multiple turbulence fan blades 20.

[0018] Furthermore, the drive assembly 11 includes a fixed bracket 111, with a bottom-opening ring-shaped guide rail 112 fixedly connected to the upper end of the fixed bracket 111. Motors 113 are symmetrically fixedly connected to the left and right sides of the front end of the fixed bracket 111. A transmission gear ring 114 is installed at the output end of the motor 113, and the two transmission gear rings 114 are meshed with the external gear ring 10.

[0019] The motor 113 drives the transmission gear ring 114 to rotate, which in turn drives the outer gear ring 10 to rotate through meshing, so that the center hole of the disc wheel 124 to be processed is inserted into it. After the outer gear ring 10 has rotated one full revolution, the disc wheel 124 to be processed falls back onto the conveyor belt through its opening. During this process, the workpiece is briefly lifted so that it is separated from the contact part of the conveyor belt, ensuring that the surface is heated evenly and that the shrinkage effect of the film is consistent.

[0020] Preferably, the equipment component 12 includes a heating chamber 121, a roller-type electric conveyor belt 122 installed on the lower inner wall of the heating chamber 121, flexible baffles 123 symmetrically fixedly connected to the front and rear ends of the heating chamber 121, the two flexible baffles 123 being located at the inlet and outlet of the heating chamber 121 respectively, multiple sets of processing discs 124 are assembled at the upper end of the roller-type electric conveyor belt 122, and two fixed brackets 111 are fixedly connected to the left and right inner walls of the heating chamber 121 respectively.

[0021] The heating chamber 121 provides core heat energy for the disc wheel 124 to be processed. The flexible curtains 123 at the front and rear inlets and outlets can effectively block the heat from leaking out of the chamber, maintain a stable high-temperature environment inside the chamber, reduce energy consumption, and prevent external dust and impurities from entering, thus avoiding contamination of the disc wheel 124 to be processed. Moreover, the flexible material can open and close naturally with the workpiece entering and exiting, without affecting the conveying process.

[0022] In use, when the disc wheel 124 to be processed is in an upright state and moves on the roller-type electric conveyor belt 122, it can move through to the position of the intermittent lifting component. When the central hole of the disc wheel 124 to be processed is aligned with the end of the external gear ring 10, the drive component 11 immediately starts to work. The fixed bracket 111 provides stable support for each component of the drive component 11, and the bottom open ring-shaped guide rail 112 at its upper end provides a precise movement trajectory for the external gear ring 10 to avoid jamming during its movement. After the motor 113 on the fixed bracket 111 starts, it will drive the transmission gear ring 114 at its output end to rotate synchronously. Since the transmission gear ring 114 and the external gear ring 10 are in a meshing connection, the rotation of the transmission gear ring 114... The external gear ring 10 will be directly driven to rotate along the bottom open circular guide rail 112. During this process, the central hole of the disc wheel 124 to be processed will be inserted into the external gear ring 10. As the external gear ring 10 completes a full rotation, the disc wheel 124 to be processed will slowly descend through the bottom opening structure of the external gear ring 10 and return to the initial bearing position of the roller-type electric conveyor belt 122. The entire lifting and resetting process realizes a brief lifting operation of the disc wheel 124 to be processed, so that the part that was originally in contact with the roller-type electric conveyor belt 122 is temporarily separated, so that all areas of the surface of the disc wheel 124 to be processed can be evenly contacted with the heat energy in the heating chamber 121, ensuring that the subsequent film shrinkage effect is uniform.

[0023] Example 2 Reference Figure 2-4 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a linkage rotation assembly 22 including two side inner supports 221. The two side inner supports 221 are respectively fixedly connected to the left and right inner walls of the heating chamber 121. A pair of transverse rotating shafts 222 are assembled at the end of the side inner supports 221 near the outer gear ring 10. The two transverse rotating shafts 222 are arranged vertically. Multiple turbulence fan blades 20 are sequentially fixedly connected to the end of the transverse rotating shafts 222 near the outer gear ring 10. The multiple upper and lower turbulence fan blades 20 are staggered. A vertical spring 223 is fixedly connected between the two staggered turbulence fan blades 20. A counter-rotating linkage gear 224 is fixedly connected to the middle of the transverse rotating shaft 222. The upper and lower counter-rotating linkage gears 224 are meshed together. The protruding striking short shaft 21 is in intermittent contact with the nearest turbulence fan blade 20.

[0024] Specifically, when the external gear ring 10 rotates, the protruding short shaft 21 at the front end makes a circular motion. When it rotates to the position of the turbulence component, it intermittently pushes the adjacent turbulence fan blades 20 to swing. The vertical horizontal rotating shaft 222 meshes with the opposing linkage gear 224. When the upper one rotates, it drives the lower one to rotate in the opposite direction, so that the staggered turbulence fan blades 20 form a reverse turbulence. With the help of the vertical spring 223, it can buffer the impact and assist in the reset, improve the turbulence intensity, and ensure that the heat in the heating chamber 121 is evenly applied to the disc wheel 124 to be processed.

[0025] In use, when the external gear ring 10 rotates, the multiple protruding striking short shafts 21 fixed at its front end will also perform circular motion. When the protruding striking short shafts 21 rotate to the position of the auxiliary turbulence assembly 20, they will intermittently contact the nearest turbulence fan blade 20 and push the turbulence fan blade 20 to swing. The turbulence fan blade 20 is fixed on the transverse rotating shaft 222 of the linkage rotating assembly 22. The side inner bracket 221 provides assembly support for the transverse rotating shaft 222. The two transverse rotating shafts are arranged vertically. 222 meshes with the opposing linkage gear 224 in the middle. When the upper horizontal rotating shaft 222 rotates, it will drive the lower horizontal rotating shaft 222 to rotate in the opposite direction through the opposing linkage gear 224, so that the upper and lower staggered turbulence fan blades 20 form reverse turbulence. At the same time, the vertical spring 223 between the upper and lower turbulence fan blades 20 can buffer the swing impact force and assist the turbulence fan blades 20 to reset, thereby improving the turbulence intensity of the entire component and ensuring that the heat in the heating chamber 121 is evenly applied to the disc wheel 124 to be processed.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
