DETAILED DESCRIPTION

[0025] To describe the technical content, structural features, achieved purpose and effect 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 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.

[0026] The embodiment of the present application provides an integrated winding and unwinding machine for winding products and having the function of unwinding fully rolled products.

[0027] like Figure 1-3 As shown, the winding and unwinding integrated machine 100 includes a frame 1, a first roller 2, a driving mechanism 3, a second roller 4 and an unwinding mechanism 5. The frame 1 includes a pair of wall panels 11 arranged opposite to each other on the left and right sides, and the first roller 2 is arranged between the pair of wall panels 11 so as to be rotatable around its own axis. The driving mechanism 3 is connected to the first roller 2 in a transmission manner to drive the first roller 2 to rotate around its own axis. The first roller 2 and the second roller 4 are both extended in the left and right directions, and the second roller 4 is arranged at the rear side of the first roller 2 without contacting the first roller 2. The second roller 4 is connected to the first roller 2 in a transmission manner so as to rotate synchronously with the first roller 2 at the same linear speed. The synchronously rotating first roller 2 and second roller 4 are in contact with the product to realize friction winding of the product. The unwinding mechanism 5 can drive the second roller 4 to rotate around the first roller 2, and when the second roller 4 rotates to a position lower than the first roller 2, the product is unwound.

[0028] like Figure 2-4As shown in the figure, the driving mechanism 3 includes a driving motor 31 and a gear assembly 32 that is drivingly connected between the first roller 2 and the driving motor 31. The gear assembly 32 includes a first gear 321 coaxially arranged with the transmission shaft of the driving motor 31, a second gear 322 coaxially arranged with the first roller 2, and a third gear 323 that meshes with both the first gear 321 and the second gear 322. When the driving motor 31 operates, the sequentially meshing first gear 321, third gear 323, and second gear 322 transmit the power of the driving motor 31 to the first roller 2, causing the first roller 2 to rotate relative to a pair of wall plates 11 about its own axis X1. In the embodiment of the present application, the driving motor 31 is a torque motor, and the torque motor drives the first roller 2 to rotate continuously for winding, ensuring a stable winding tension.

[0029] As Figure 1-4 shown, a transmission mechanism 6 is drivingly connected between the first roller 2 and the second roller 4. The transmission mechanism 6 includes a fourth gear 61 coaxially arranged with the first roller 2, a fifth gear 62 coaxially arranged with the second roller 4, and a sixth gear 63 that meshes with both the fourth gear 61 and the fifth gear 62. The first roller 2 rotates about its own axis X1 under the drive of the driving mechanism 3, and the fourth gear 61 coaxially arranged with the first roller 2 also rotates. The sixth gear 63 that meshes with the fourth gear 61 transmits the power to the fifth gear 62, causing the second roller 4 coaxially arranged with the fifth gear 62 to rotate about its own axis X2. The roller diameter of the first roller 2 is the same as that of the second roller 4, and the specifications of the fourth gear 61 and the fifth gear 62 are the same, so that the second roller 4 rotates synchronously with the same linear speed as the first roller 2.

[0030] The gear assembly 32 transmits the power of the driving motor 31 to the first roller 2 to drive the first roller 2 to rotate actively; the transmission mechanism 6 transmits the power of the first roller 2 to the second roller 4, causing the second roller 4 to rotate actively. The actively rotating first roller 2 and second roller 4 perform friction winding on the product.

[0031] The unwinding mechanism 5 includes a pair of unwinding swing arms 51 and a pair of unwinding cylinders 52 respectively connected to the pair of unwinding swing arms 51. The pair of unwinding swing arms 51 are respectively located outside the pair of wall plates 11 and are rotatably arranged at both ends of the first roller 2. The second roller 4 is rotatably disposed through the pair of unwinding swing arms 51. When the pair of unwinding swing arms 51 swing around the first roller 2, the second roller 4 swings relative to the first roller 2 along with the unwinding swing arms 51.

[0032] As Figure 1 、 5As shown, a pair of uncoiling swing arms 51 swing back and forth around the first roller 2 driven by a pair of uncoiling cylinders 52. The pair of uncoiling swing arms 51 have a coiling position and an uncoiling position. When the pair of uncoiling swing arms 51 are in the coiling position, the axis line X2 of the second roller 4 is directly behind the axis line X1 of the first roller 2. The product is frictionally coiled on the horizontally placed first roller 2 and second roller 4 through the rotation of the first roller 2 and the second roller 4. When the pair of uncoiling swing arms 51 are in the uncoiling position, the axis line X2 of the second roller 4 is below the axis line X1 of the first roller 2. The downwardly inclined second roller 4 enables the coiled product to roll backward between the first roller 2 and the second roller 4, realizing uncoiling.

[0033] As Figure 2 , 4 shown, in order to avoid interference between the gear assembly 32 and the transmission mechanism 6, the gear assembly 32 is located inside a pair of wall plates 11, the transmission mechanism 6 is arranged outside the corresponding uncoiling swing arm 51, and the sixth gear 63 is rotatably arranged on the uncoiling swing arm 51.

[0034] When the coiling and uncoiling integrated machine is working, a pair of uncoiling cylinders 52 drive a pair of uncoiling swing arms 51 to swing to the coiling position. The second roller 4 is directly behind the first roller 2 and rotates synchronously with the first roller 2 under the action of the driving mechanism 3 and the transmission mechanism 6. The operator manually starts to wind the product onto the roll. After the product is wound onto the roll, the first roller 2 and the second roller 4 perform frictional coiling on the product. After the product is fully wound, the staff cuts the product and packs the fully wound product. A pair of uncoiling cylinders 52 drive a pair of uncoiling swing arms 51 to swing to the uncoiling position. The second roller 4 rotates to the lower side behind the first roller 2, and the fully wound product rolls backward to realize uncoiling. After the product is uncoiled, a pair of uncoiling cylinders 52 drive a pair of uncoiling swing arms 51 back to the coiling position for the next coiling.

[0035] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art of this industry should understand that the present application is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present application. Without departing from the spirit and scope of the present application, the present application will have various changes and improvements.
