Description

Technical Field

Detailed Implementation

[0024] 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.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1 Reference Figures 1-3 This is the first embodiment of the present invention. This embodiment provides a cold-rolled steel strip slitting device. The cold-rolled steel strip slitting device includes a collection component 200 and a cooling component 300. The collection component 200 can collect steel chips, reducing the difficulty of manual cleaning. The cooling component 300 cools down the cutter roller 102, preventing the cutter roller 102 from wearing out faster and increasing the maintenance frequency.

[0028] Specifically, the main component 100 includes a frame 101, a cutter roller 102, an abutment roller 103, a drive unit 104, and a take-up roller 105. The cutter roller 102 is disposed on one side of the inner cavity of the frame 101, the abutment roller 103 is disposed on the top of the cutter roller 102, the drive unit 104 is disposed on one side of the cutter roller 102, and the take-up roller 105 is rotatably connected to the other side of the inner cavity of the frame 101 via bearings; and, The collection assembly 200 includes a collection frame 201, a collection pipe 202, an exhaust fan 203, a filter screen 204, a sliding member 205, a cleaning member 206, and a storage member 207. The collection frame 201 is fixedly connected to one side of the bottom of the inner cavity of the frame 101. The collection pipe 202 is disposed on one side of the frame 101, with one side of the collection pipe 202 penetrating the frame 101 and communicating with the collection frame 201. The exhaust fan 203 is fixedly connected to the other side of the collection pipe 202. The filter screen 204 is disposed on one side of the inner cavity of the exhaust fan 203. The sliding member 205 is disposed on one side of the filter screen 204. The cleaning member 206 is disposed on one side of the sliding member 205. The storage member 207 is located at the bottom of the filter screen 204. The cooling assembly 300 includes a cooling component 301 and a fan component 302. The cooling component 301 is fixedly connected to the other side of the bottom of the inner cavity of the frame 101, and the fan component 302 is fixedly connected to one side of the drive component 104.

[0029] The drive unit 104 can drive the cutter roller 102 and the abutment roller 103 to rotate, thereby slitting the steel coil, and the take-up roller 105 can take it back. This is the prior art, and those skilled in the art can set it up according to their needs.

[0030] Steel shavings can be collected through the collection box 201 to prevent them from falling directly onto the frame 101. The exhaust fan 203 generates airflow to collect the steel shavings in the collection box 201 into the collection pipe 202. The steel shavings are then filtered through the filter screen 204 and, under the action of the cleaning component 206, enter the inner cavity of the storage component 207 for storage, so as to facilitate centralized recycling. The sliding component 205 can limit the position of the filter screen 204 to increase its stability.

[0031] By providing coolant in the cooling component 301, the circular cutter on the surface of the cutter roller 102 will come into contact with the coolant when the roller rotates, thereby cooling it down. The fan-shaped component 302 can increase airflow, further cooling the circular cutter.

[0032] Specifically, the cooling component 301 includes a cooling frame 301a fixedly connected to the other side of the bottom of the inner cavity of the frame 101, a cutter roller 102 passing through the cooling frame 301a and extending into the cooling frame 301a, and a water storage tank 301b fixedly connected to one side of the frame 101 and cooperating with the cooling frame 301a.

[0033] The coolant in the cooling box 301a cools the cutter roller 102. During long-term use, the coolant stored in the water tank 301b can be circulated with the coolant in the cooling box 301a to ensure the cooling effect on the cutter roller 102. The water storage tank 301b is equipped with a circulation pump, which connects the cooling frame 301a and the water storage tank 301b. At the same time, a return pipe is also connected between the cooling frame 301a and the water storage tank 301b. Thus, the coolant in the cooling frame 301a and the water storage tank 301b can be circulated by the circulation pump. This is existing technology and will not be described in detail.

[0034] Specifically, the fan 302 includes a fan blade 302a fixedly connected to one side of the first rotating shaft 104d, and a ventilation hole 302b is provided on the other side of the frame 101.

[0035] When the first rotating shaft 104d drives the cutter roller 102 to rotate for slitting, it will simultaneously drive the fan blade 302a to rotate. At this time, the fan blade 302a can generate wind power, which enters the cutter roller 102 through the ventilation hole 302b, improving the air exchange efficiency and further cooling the cutter roller 102.

[0036] Example 2 Reference Figures 3-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the drive unit 104 includes a motor 104a fixedly connected to one side of the frame 101. The output shaft of the motor 104a is fixedly connected to a synchronous belt 104b. A drive gear 104c is provided on one side of the synchronous belt 104b. A first rotating shaft 104d is fixedly connected to one side of the drive gear 104c. The motor 104a and the first rotating shaft 104d are connected by transmission through the synchronous belt 104b. One side of the first rotating shaft 104d passes through the frame 101 and is fixedly connected to the fan-driven member 302. The cutter roller 102 is fixedly connected to the surface of the first rotating shaft 104d.

[0038] The motor 104a drives the synchronous belt 104b, the drive gear 104c and the first rotating shaft 104d to rotate, thereby driving the cutter roller 102 to rotate and slit the steel strip. The slitting width can be changed by adjusting the blade spacing of the circular blades on the cutter roller 102. This is existing technology and can be set by those skilled in the art according to actual needs.

[0039] Specifically, the drive component 104 also includes a driven gear 104e meshing with the top of the drive gear 104c. A second rotating shaft is fixedly connected to one side of the driven gear 104e. The second rotating shaft passes through the frame 101 and is rotatably connected to the frame 101 through a bearing. The abutment roller 103 is fixedly connected to the surface of the second rotating shaft.

[0040] By meshing the drive gear 104c and the driven gear 104e, the abutment roller 103 and the cutter roller 102 can rotate in opposite directions. When the steel strip passes between the abutment roller 103 and the cutter roller 102, the steel strip can be slit by the cooperation of the abutment roller 103 and the cutter roller 102. This is existing technology and will not be described in detail.

[0041] Specifically, the sliding member 205 includes a slider 205a fixedly connected to both sides of the filter screen 204, and grooves 205b are provided on both sides of the inner cavity of the collection tube 202, which cooperate with the slider 205a.

[0042] The cooperation between slider 205a and groove 205b allows the filter screen 204 to be guided along the direction of groove 205b when it moves, thus preventing it from colliding with the collection pipe 202.

[0043] Specifically, the cleaning component 206 includes a drive shaft 206a fixedly connected to one side of the exhaust fan 203, a push plate 206b fixedly connected to one side of the drive shaft 206a, a triangular block 206c provided on one side of the push plate 206b and in contact with the push plate 206b, and the triangular block 206c fixedly connected to one side of the filter screen 204.

[0044] The rotation of the exhaust fan 203 will drive the drive shaft 206a and the push plate 206b to rotate together. One side of the triangular block 206c is a slope. When the push plate 206b contacts the slope, it will push the triangular block 206c to move the filter screen 204, causing the steel chips on the filter screen 204 to shake and fall off, thus preventing the steel chips from clogging and affecting the ventilation efficiency.

[0045] Specifically, the cleaning component 206 also includes a spring 206d fixedly connected to one side of the slider 205a, and one side of the spring 206d is fixedly connected to one side of the inner cavity of the slide groove 205b.

[0046] When the filter screen 204 moves, it will cause the slider 205a to squeeze the spring 206d. Conversely, when the push plate 206b moves away from the triangular block 206c, the spring 206d will release elastic potential energy to drive the slider 205a and the filter screen 204 to reset. This causes the filter screen 204 to cycle through the above process of movement and reset, thereby shaking off the steel chips on the filter screen 204.

[0047] Specifically, the cleaning component 206 also includes a limiting plate 206e that is rotatably connected to the surface of the drive shaft 206a via a bearing, and the limiting plate 206e is fixedly connected to the top of the inner cavity of the collection tube 202.

[0048] The limiting plate 206e serves to limit and support the drive shaft 206a, making the drive shaft 206a more stable during rotation.

[0049] Specifically, the storage device 207 includes a through groove 207a opened at the bottom of the inner cavity of the collection tube 202, and a storage box 207b is fixedly connected to the bottom of the collection tube 202. The storage box 207b is connected to the collection tube 202 through the through groove 207a.

[0050] The dislodged steel shavings will enter the inner cavity of the storage box 207b through the channel 207a for centralized collection. It should be noted that a door is opened on one side of the storage box 207b to facilitate subsequent cleaning. This is existing technology and will not be elaborated further.

[0051] In operation, the motor 104a drives the synchronous belt 104b and the first rotating shaft 104d to rotate. This, through the meshing of the driving gear 104c and the driven gear 104e, causes the cutter roller 102 and the abutment roller 103 to rotate in opposite directions, thus slitting the steel strip. During slitting, steel chips are collected by the collection frame 201, and the exhaust fan 203 generates suction to draw the chips into the collection pipe 202, where they are filtered by the filter screen 204. The exhaust fan 203, while operating, will... The drive shaft 206a and push plate 206b rotate, causing the triangular block 206c to move the filter screen 204. During the movement, the slider 205a compresses the spring 206d. Then, when the push plate 206b moves away from the triangular block 206c, the spring 206d will cause the filter screen 204 to return to its original position. The movement and return of the filter screen 204 are then repeated, causing the steel chips to fall off and enter the storage box 207b for collection, which can effectively reduce the difficulty of subsequent cleaning.

[0052] When the cutter roller 102 rotates, the circular cutter on its surface comes into contact with the coolant in the cooling frame 301a, thereby cooling it down. At the same time, when the first rotating shaft 104d rotates, it drives the fan blade 302a to rotate together, thereby accelerating the airflow through the fan blade 302a, which can further cool the cutter roller 102 and reduce the wear of the cutter roller 102.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. 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.
