[0022] In order to describe the technical content, structural features, achieved purposes and effects of the application in detail, the technical solutions in the embodiments of the application will be described below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all of the embodiments. In the following description, for the purpose of explanation, many specific details are set forth to provide a detailed description of various exemplary embodiments or implementations of the invention. However, various exemplary embodiments may also be implemented without these specific details or in the case of one or more equivalent arrangements. In addition, various exemplary embodiments may be different, but are not necessarily exclusive. For example, without departing from the inventive concept, the specific shape, structure and characteristics of the exemplary embodiment may be used or implemented in another exemplary embodiment.

[0023] The present application embodiment provides a fully automatic winding machine, such as Figure 1 As shown, the fully automatic winding machine includes a storage mechanism 1, a traction mechanism 2, an upper roll cutting mechanism 3 and a winding mechanism 4 arranged in sequence from front to back. The traction mechanism 2 is installed at the rear end of the storage mechanism 1 to form an integral device, and the upper roll cutting mechanism 3 is installed on the winding mechanism 4 to form an integrated device, which saves installation space and is easy to install and maintain.

[0024] The storage mechanism 1 includes a frame 11 and a plurality of upper storage rollers 12 and a plurality of lower storage rollers 13 rotatably arranged on the frame 11 around their own axis. The plurality of upper storage rollers 12 and the plurality of lower storage rollers 13 are arranged alternately from front to back, and the products pass through the plurality of upper storage rollers 12 and the plurality of lower storage rollers 13 in an "S" shape from front to back. The storage mechanism 1 also includes a movable frame 14 slidably mounted on the frame 11. The movable frame 14 is mounted on the frame 11 so as to be movable in the up and down directions. The plurality of upper storage rollers 12 are rotatably mounted on the movable frame 14. When the movable frame 14 moves upward, the upper storage rollers 12 move away from the lower storage rollers 13 to increase the moving path of the products in the storage mechanism 1, thereby achieving temporary storage. When the movable frame 14 moves downward, the upper storage rollers 12 move closer to the lower storage rollers 13 to reduce the moving path of the products in the storage mechanism 1, thereby releasing the temporarily stored products. The storage mechanism 1 temporarily stores the products when the winding mechanism 4 is changing the roll, thereby realizing online roll changing and continuous winding, saving roll changing time and improving winding efficiency.

[0025] The traction mechanism 2 is installed at the rear end of the storage mechanism 1. The traction mechanism 2 is used to pull the product backward from the storage mechanism 1. The traction mechanism 2 includes a traction frame 21 and a pair of traction rollers 22 arranged opposite to each other up and down. The pair of traction rollers 22 are respectively installed on the traction frame 21 so as to rotate around their own axis. The upper traction roller 22 is installed on the traction frame 21 so as to be movable in the up and down directions. The upper traction roller 22 presses the product against the lower traction roller 22. The upper and lower traction rollers 22 rotate to pull the product toward the rear.

[0026] like Figure 1-3 As shown, the winding mechanism 4 is arranged at the rear side of the traction mechanism 2. The winding mechanism 4 includes a winding station 41, a pair of pneumatic shafts 42 that rotate alternately to the winding station 41, a main frame 43, a rotating bracket 44 rotatably mounted on the main frame 43 about a centerline X1, and an unwinding station 45. The winding station 41 is located at the front end of the main frame 43, and the unwinding station 45 is located at the rear end of the main frame 43. The pair of pneumatic shafts 42 extend in the left-right direction. After rotating to the winding station 41, the pneumatic shafts 42 rotate about their own axis within the winding station 41 to wind the product. A pair of inflatable shafts 42 are relatively arranged on a rotating bracket 44 with the center line X1 as the center. Each inflatable shaft 42 is installed on the rotating bracket 44 so that it can rotate around its own axis. The rotating bracket 44 flips 180° around the center line X1, so that the pair of inflatable shafts 42 rotate alternately to the winding station 41, and are wound at the winding station 41. The fully rolled inflatable shaft 42 is flipped to the unwinding station 45 to wait for unwinding.

[0027] like Figure 2-4As shown, the upper roll cutting mechanism 3 is mounted on the main frame 43 of the winding mechanism 4, and the upper roll cutting mechanism 3 is arranged adjacent to the winding station 41. The upper roll cutting mechanism 3 includes an upper roll assembly 31 and a cutting assembly 32.

[0028] The roll-up assembly 31 includes a roll-up support 311 that can move vertically, a spring shaft 312 rotatably mounted on the roll-up support 311, and a rubber roller 313. The roll-up support 311 is slidably mounted on the main frame 43. A lifting assembly 33 is drivingly connected between the roll-up support 311 and the main frame 43. The lifting assembly 33 includes a lifting cylinder 331, a lifting guide rail 332 extending vertically, and a slider 333 that slidably engages with the lifting guide rail 332. The lifting guide rail 332 is mounted on the main frame 43, and the slider 333 is mounted on the roll-up support 311. The cylinder body of the lifting cylinder 331 is mounted on the main frame 43, and the gas rod of the lifting cylinder 331 is connected to the roll-up support 311. The lifting cylinder 331 drives the roll-up support 311 to move vertically. Driven by the lifting cylinder 331, the roll-up support 311 has a first position positioned within the winding station 41 and a second position positioned below the winding station 41, and can switch back and forth between the first and second positions. When the pneumatic shaft 42 for roll change rotates to the winding station 41, the lifting cylinder 331 drives the upper roll bracket 311 to move upward to the first position, so that the upper roll assembly 31 and the cutting assembly 32 are close to the pneumatic shaft 42 of the winding station 41, thereby facilitating the cutting assembly 32 to cut the product and roll up the pneumatic shaft 42 of the winding station 41; after the pneumatic shaft 42 after roll change is rolled up, the lifting cylinder 331 drives the winding bracket 311 to move downward to the second position.

[0029] The spring shaft 312 and the rubber roller 313 are both parallel to the air shaft 42. The rubber roller 313 is located on the front side of the spring shaft 312, and presses the product onto the air shaft 42 from the front and rear sides of the air shaft 42 on the winding station 41, ensuring that the end surface of the product is neat when the cutting assembly 32 cuts it.

[0030] The upper winding assembly 31 includes a pressing cylinder 314 connected to the rubber roller 313 and a support seat 315 connected to the spring shaft 312. The pressing cylinder 314 can drive the rubber roller 313 to move from front to back to press the product onto the inflatable shaft 42.

[0031] A spring member is connected between the spring shaft 312 and the support base 315, allowing the spring shaft 312 to be floatingly mounted on the support base 315. A gear assembly is transmission-connected between the support base 315 and the upper roll support 311. When the upper roll support 311 is in the first position, the gear assembly can drive the support base 315 and the spring shaft 312 on the support base 315 to rotate along the axis of the pneumatic shaft 42 located in the winding station 41.

[0032] The cutting assembly 32 includes a cutting blade 321 for cutting the product. The cutting blade 321 is mounted on the upper roll support 311 so as to be movable in the left-right direction.

[0033] The working principle of the fully automatic winding machine is as follows: the product is rolled up onto the inflatable shaft 42 of the winding station 41 after passing through the storage mechanism 1 and the traction mechanism 2, and the inflatable shaft 42 on the winding station 41 rotates around its own axis, so that the product is wound on the inflatable shaft 42; when the inflatable shaft 42 of the winding station 41 is fully rolled, the storage mechanism 1 temporarily stores the product in advance, the rotating bracket 44 flips 180°, the fully rolled inflatable shaft 42 enters the unloading station 45, and the empty inflatable shaft 42 flips and enters the winding station 41; the upper rolling bracket 311 moves to the first position, and the rubber roller 313 moves backward under the drive of the pressing cylinder 314 to press part of the product against the front side of the inflatable shaft 42 of the winding station 41, and the spring shaft 312 presses the product against the winding under the elastic action of the spring member The rear side of the air shaft 42 of station 41 tightens the product between the unwinding station 45 and the spring shaft 312. The cutter 321 moves left and right behind the spring shaft 312 to cut the product between the spring shaft 312 and the unwinding station 45. Driven by the gear assembly, the spring shaft 312 rotates counterclockwise along the circumference of the air shaft 42 of the winding station 41, causing the beginning of the cut product to be wound onto the air shaft 42. The air shaft 42 of the winding station 41 rotates several times to complete the winding. The rubber roller 313 moves forward to move away from the air shaft 42. The spring shaft 312 rotates clockwise along the circumference of the air shaft 42 of the winding station 41. The winding support 311 moves downward to its second position. The air shaft 42 of the winding station 41 rotates again to resume normal winding. The air shaft 42 of the unwinding station 45 and the fully wound product thereon are unloaded from the unwinding station 45.

[0034] The fully automatic winding machine of the present application has a simple structure and low cost. The material storage and traction are integrated into an integral device. The traction, roll changing and rolling are integrated into an integral device, which saves installation space and realizes automatic roll changing, automatic rolling and automatic winding. It has a high degree of automation and improves the winding efficiency.
