[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 1-5 The automatic roll changing device of the metal card clothing wrapping machine includes a base 1, two fixed frames 5 are symmetrically installed on the top surface of the base 1, and a cutting assembly 4 is commonly installed on the outer sides of the two fixed frames 5, and a turntable 2 is rotatably connected to the outer side of one of the fixed frames 5, and a plurality of first electric telescopic rods 8 are symmetrically rotatably connected to the outer side of the turntable 2, and a fixed seat 9 is fixedly installed on the outer side of each first electric telescopic rod 8, and a sealing cylinder 11 is fixedly installed on the outer side of each fixed seat 9 through a plurality of connecting rods 10, and a clamping assembly 3 is installed in each sealing cylinder 11, and a plurality of second electric telescopic rods 12 are symmetrically installed on the outer side of each sealing cylinder 11, and a clamping rod 13 is fixedly installed on the other end of each second electric telescopic rod 12.

[0027] It is worth noting that the rotation of each first electric telescopic rod 8 is driven by an external independent driving source.

[0028] like Figure 1-5 As shown, the embodiment is specifically as follows: by arranging a turntable 2, a first electric telescopic rod 8, and a clamping assembly 3, the clamping assembly 3 is used to clamp the rotating shaft from the inside, and the first electric telescopic rod 8 at the top is driven to rotate by an external driving source, thereby wrapping the metal card clothing. Then, when the rotating shaft at the top needs to be replaced, the turntable 2 can be rotated to rotate the rotating shaft to be replaced to the top, and the clamping rod 13 can be driven by the second electric telescopic rod 12 to clamp the metal card clothing. At the same time, the cutting assembly 4 facilitates cutting of the metal card clothing, and then the first electric telescopic rod 8 at the top is rotated to allow the replaced rotating shaft to continue to wrap the metal needle package.

[0029] In a preferred embodiment, each clamping assembly 3 includes a first piston 14, and each first piston 14 is slidably connected to the corresponding sealing cylinder 11, and the outer side of each first piston 14 is fixedly connected to the extended end of the corresponding first electric telescopic rod 8, the outer side of each sealing cylinder 11 is fixed and connected to the fixed cylinder 15, each fixed cylinder 15 is slidably connected to the second piston 18, and the outer side of each second piston 18 is installed with a support rod 16 through a connecting column 19. It is worth noting that the installation position of the fixed seat 9 is located outside the telescopic base of the first electric telescopic rod 8, and then the extension of the first electric telescopic rod 8 can drive the first piston 14 to slide, thereby pushing the air into the fixed cylinder 15, and causing the support rod 16 to slide outward through the second piston 18, thereby fixing and clamping the rotating shaft.

[0030] In a preferred embodiment, the cutting assembly 4 includes two tilting frames 7, and the two tilting frames 7 are respectively installed on the outside of the fixed frame 5 at corresponding positions. The two tilting frames 7 are jointly installed with an assembly seat 24, and a threaded rod 23 is rotatably connected inside the assembly seat 24. A threaded sleeve 21 is threadedly connected to the threaded rod 23, and a cutting blade 22 is fixedly installed on the bottom surface of the threaded sleeve 21.

[0031] In a preferred embodiment, an annular baffle 17 is installed in each fixed cylinder 15 , and each annular baffle 17 is provided with a through groove, so that the annular baffle 17 prevents the second piston 18 from entering the sealing cylinder 11 .

[0032] In a preferred embodiment, the second motor 20 is fixedly mounted on the outer side of the assembly seat 24 , and the output shaft of the second motor 20 passes through the assembly seat 24 and is connected to the threaded rod 23 .

[0033] In a preferred embodiment, a first motor 6 is fixedly mounted on the outer side of one of the fixing frames 5 , and an output shaft of the first motor 6 is connected to the turntable 2 .

[0034] In a preferred embodiment, a rubber plate is installed on the upper end surface of each support rod 16, and each clamping rod 13 is made of unidirectional rubber material. It is worth noting that each clamping rod 13 can be elastically deformed downward, and when an upward force is applied, the clamping rod 13 is rigid, so that when the metal card clothing is covered on the clamping rod 13, the clamping rod 13 is deformed, and the metal card clothing enters between the clamping rod 13 and the sealing cylinder 11, and then the clamping rod 13 can fix and clamp the metal card clothing through the second electric telescopic rod 12.

[0035] In a preferred embodiment, a square cavity is defined in the assembly seat 24 , and each side surface of the threaded sleeve 21 is in contact with the side wall of the square cavity, thereby limiting the threaded sleeve 21 and preventing it from rotating.

[0036] When the utility model is used, the first piston 14 is driven to slide in the sealing cylinder 11 by starting the multiple first electric telescopic rods 8, thereby pushing the air in the sealing cylinder 11 into the fixed cylinder 15, and then the support rod 16 is slid outward by the sliding of the second piston 18, and the rotating shaft is clamped from the inside, and the multiple rotating shafts are clamped on the outside of the turntable 2 through the clamping assembly 3, and then the rotating shaft at the highest point is rotated to wrap the metal card clothing. When the rotating shaft is wrapped, the first motor 6 is started to rotate the turntable 2 ninety degrees, thereby driving the empty rotating shaft to be at the highest point. At this time, the metal card clothing is The card clothing is in a tensioned state, and when the turntable 2 rotates, the metal card clothing exerts an extruding force on the clamping rod 13, thereby deforming the clamping rod 13 and entering between the clamping rod 13 and the sealing cylinder 11. Then, the clamping rod 13 is driven to slide downward by the second electric telescopic rod 12, thereby clamping the metal card clothing. Then, the second motor 20 is started to rotate the threaded rod 23, thereby driving the threaded sleeve 21 to slide and cutting the metal card clothing by the cutting blade 22. Then, the driving source is started to drive the first electric telescopic rod 8 located at the highest point to rotate to complete the reeling of the metal card clothing.

[0037] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
