[0007] According to the above design scheme, a connecting plate is fixedly connected to the top of the fixing plate. A round shaft penetrates through the side surface of the connecting plate. An acting block is fixedly connected to the circumferential surface of the round shaft. A screw assembly is arranged on the top of the acting block. Such a design is beneficial for the acting block to rotate through the round shaft when the acting block is toggled.

[0008] According to the above design scheme, the top of the fixed plate is set to an adaptive semicircular shape, and the top of the fixed plate and the winding shaft are adapted to each other. Such a design is conducive to the winding shaft being able to be placed stably on the top of the fixed plate.

[0009] According to the above design scheme, a dust removal device is provided on the side of the fixed plate, and the dust removal device includes a receiving plate, and the receiving plate is fixedly connected to the side of the fixed plate. The side of the fixed plate is rotatably connected to a rotating shaft, and the circumferential surface of the rotating shaft is fixedly connected to a worm gear.

[0010] According to the above design scheme, the circumferential surface of the rotating shaft is fixedly connected to a fixing ring, the circumferential surface of the fixing ring is fixedly connected to a fan blade, and a vacuum cleaner is arranged inside the support plate. Such a design is conducive to driving the fixing ring to rotate clockwise when the rotating shaft is forced to rotate clockwise.

[0011] According to the above design scheme, there are two worm wheels, which are symmetrical to each other along the vertical central axis of the top of the support plate.

[0012] According to the above design scheme, the winding shaft is located directly above the motor, and two trimming assemblies are provided, and the distance between the two is adapted to the width of the cold-rolled steel strip. Such a design is advantageous in that when the cold-rolled steel strip is wound into the circumferential surface of the winding shaft, the burrs on both sides of the cold-rolled steel strip can be ground off by the trimming circular knife on the inner wall of the trimming assembly.

[0013] According to the above design scheme, there are several fan blades, and they are arranged in a circular array on the circumferential surface of the rotating shaft. The teeth and gears are engaged with each other. This design is beneficial for the fan blades to rotate when the fixing ring rotates clockwise, generating wind.

Specific Embodiments

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0025] Embodiment 1

[0026] As Figures 1 to 2, in this embodiment, a cold-rolled steel strip fixing and trimming device is proposed, which includes a support plate 1 and a trimming assembly 2. The trimming assembly 2 is fixedly connected to the top of the support plate 1. A trimming circular knife 3 is arranged on the inner wall of the trimming assembly 2. A unwinding assembly 4 is fixedly connected to the top of the support plate 1. A trimming device 5 is arranged on the top of the support plate 1; The trimming device 5 includes a fixing plate 51, the fixing plate 51 is fixedly connected to the top of the support plate 1. A motor 52 penetrates through the side of the fixing plate 51. The end of the output shaft of the motor 52 is fixedly connected to a rotating shaft 53. A first worm 54 is fixedly connected to the circumferential surface of the rotating shaft 53. One end of the first worm 54 far from the rotating shaft 53 is fixedly connected to a rotating rod 55. A second worm 56 is fixedly connected to the circumferential surface of the rotating rod 55. One end of the second worm 56 far from the rotating rod 55 is fixedly connected to a stress shaft 57. A gear 58 is fixedly connected to the circumferential surface of the stress shaft 57. A winding shaft 59 is arranged on the top of the fixing plate 51. Tooth teeth 510 are arranged on the circumferential surface of the winding shaft 59.

[0027] A connecting plate 511 is fixedly connected to the top of the fixing plate 51. A round shaft 512 penetrates through the side of the connecting plate 511. An acting block 513 is fixedly connected to the circumferential surface of the round shaft 512. A screw assembly 514 is arranged on the top of the acting block 513. Such a design is beneficial to the acting block 513 rotating through the round shaft 512 when the acting block 513 is toggled.

[0028] The top of the fixing plate 51 is set to an adaptive semi-circular shape, and the top of the fixing plate 51 is adapted to the winding shaft 59. Such a design is beneficial to the winding shaft 59 being able to be placed stably on the top of the fixing plate �1.

[0029] In this embodiment, first, when the staff needs to trim the cold-rolled steel strip, the cold-rolled steel strip is placed in the unwinding assembly 4 and the reeling shaft 59, the external power supply is turned on, and the motor 52 is started. When the motor 52 drives the rotating shaft 53 to rotate clockwise, it drives the first worm 54 to rotate clockwise, prompting the rotating rod 55 to rotate under force. When the rotating rod 55 rotates clockwise under force, the second worm 56 fixed on the circumferential surface of the rotating rod 55 is forced to rotate clockwise, causing the force-bearing shaft 57 to rotate accordingly under force. When the force-bearing shaft 57 rotates clockwise, the gear 58 fixed on the circumferential surface of the force-bearing shaft 57 rotates clockwise, forcing the reeling shaft 59 to rotate through the teeth meshing with the gear 58. 510 is rotated counterclockwise under the force. When the reel 59 rotates counterclockwise, a pulling force is applied to the cold-rolled steel strip, causing the unwinding component 4 to rotate counterclockwise. In this process, the cold-rolled steel strip is subjected to the pulling force, and the burrs on both sides of the cold-rolled steel strip are polished off after passing through the circumferential surface of the trimming circular knife 3. The cold-rolled steel strip is then slowly rolled on the circumferential surface of the reel 59. When the trimming work is completed, in order to facilitate the staff to disassemble the reel 59, the staff can unscrew the screw assembly 514 and move the action block 513 so that the action block 513 is forced to rotate through the circular shaft 512, making it convenient for the staff to remove the reel 59, thereby improving the staff's work efficiency and facilitating the staff to disassemble the reel 59.

[0030] Example 2

[0031] like Figures 3 to 5 Based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a dust removal device 6 is provided on the side of the fixed plate 51, and the dust removal device 6 includes a receiving plate 61, and the receiving plate 61 is fixedly connected to the side of the fixed plate 51. The side of the fixed plate 51 is rotatably connected to a rotating shaft 62, and the circumferential surface of the rotating shaft 62 is fixedly connected to a worm gear 63. Such a design is conducive to the rotation of the rotating shaft 62 when the worm gear 63 is forced to rotate clockwise.

[0032] The circumferential surface of the rotating shaft 62 is fixedly connected to a fixing ring 64, and the circumferential surface of the fixing ring 64 is fixedly connected to a fan blade 65. A dust collector 66 is provided inside the support plate 1. This design is conducive to driving the fixing ring 64 to rotate clockwise when the rotating shaft 62 is forced to rotate clockwise.

[0033] There are two worm wheels 63, which are symmetrical to each other along the vertical center axis of the top of the support plate 1. The worm wheel 63 is engaged with the first worm 54 and the second worm 56. This design is conducive to forcing the worm wheel 63 to rotate clockwise when the first worm 54 and the second worm 56 are both subjected to clockwise force.

[0034] The take-up reel 59 is located directly above the motor 52. There are two trimming assemblies 2, and the distance between them is adapted to the width of the cold-rolled steel strip. Such a design is beneficial for when the cold-rolled steel strip is wound onto the circumferential surface of the take-up reel 59, the burrs on both sides of the cold-rolled steel strip can be ground off by the trimming circular knives 3 on the inner wall of the trimming assembly 2.

[0035] A number of fan blades 65 are provided and are circumferentially arrayed on the circumferential surface of the rotating shaft 62. The teeth 510 are meshed with the gear 58. Such a design is beneficial for when the fixed ring 64 rotates clockwise, the fan blades 65 also rotate accordingly to generate wind.

[0036] In this embodiment, in the trimming device 5, when the trimming device 5 is working normally, since a large amount of waste chips will be generated when the cold-rolled steel strip is trimmed by the trimming circular knives 3, when the first worm 54 and the second worm 56 are forced to rotate clockwise, the worm wheel 63 is forced to rotate clockwise. When the worm wheel 63 rotates clockwise, it drives the rotating shaft 62 to rotate clockwise, prompting the fixed ring 64 fixed on the circumferential surface of the rotating shaft 62 to rotate clockwise. When the fixed ring 64 rotates clockwise, the fan blades 65 fixed on the circumferential surface of the fixed ring 64 rotate clockwise. When the fan blades 65 rotate clockwise, the fan blades 65 store and blow air towards the trimming assembly 2. At this time, when the trimming circular knives 3 perform the trimming work on the cold-rolled steel strip, the generated waste chips are further blown by the fan blades 65 towards the unwinding assembly 4. When the waste chips are blown towards the unwinding assembly 4, the dust collector 66 provided inside the support plate 1 sucks the waste chips into the dust collector 66, which is beneficial for the staff to collect the waste chips and saves the working time of the staff.

[0037] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
