Description

Technical Field

[0001] This utility model relates to the field of cold-rolled steel sheet coating technology, and in particular to a convenient cold-rolled steel sheet surface coating equipment. Background Technology

[0002] Cold-rolled steel sheet is a steel sheet produced through a cold rolling process, also known as cold plate. Compared with hot-rolled steel sheet, cold-rolled steel sheet has a more precise thickness and a smoother, more attractive surface. During the processing of cold-rolled steel sheet, in order to add a protective film to the surface of the cold-rolled steel sheet during transportation to prevent it from being scratched and affecting its use, a coating operation is required on the surface of the cold-rolled steel sheet.

[0003] Currently available coating equipment can only coat one side of the steel sheet, requiring repeated coating of the other side. This reduces coating efficiency and can lead to misalignment of the coating layer, hindering long-term use and widespread adoption. Therefore, those skilled in the art have developed a user-friendly cold-rolled steel sheet surface coating equipment to address the problems described in the background section. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a convenient cold-rolled steel sheet surface coating equipment, which solves the problem mentioned in the background technology that only facilitates coating one side of the steel sheet, and then requires repeated coating of the other side of the steel sheet, thereby reducing coating efficiency. At the same time, repeated coating can easily lead to deviations in the coating position, which is not conducive to long-term use and promotion.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a convenient cold-rolled steel sheet surface coating equipment, including a base frame, with horizontal plates fixedly installed on both the front and rear ends of the outer top surface of the base frame, and rotating rollers arranged in an array symmetrically rotatably connected between the two horizontal plates, with the ends of the two sets of several rotating rollers extending to the opposite outer side walls of the two horizontal plates respectively, and a housing threadedly fixed to the right end of the outer top and bottom surfaces of the two horizontal plates, while a support plate is fixedly installed on the left end of the outer top and bottom surfaces of one of the horizontal plates, and rotating rollers are rotatably connected to the outer side walls of the two support plates, and a coating roll is limited and sleeved on the outer surface of the two rotating rollers; the interior of the two housings is provided with processing components for compacting and cutting double-sided coated steel sheets;

[0006] Positioning components for preventing the coated steel plate from shifting are provided on the corresponding inner sidewalls of the two horizontal plates and between the roller spacing of the two rotating rollers.

[0007] As a further technical solution of this utility model, the positioning component includes a bidirectional lead screw that is rotatably connected to the bottom of the inner sidewalls of the two horizontal plates and located between the two rotating rollers. A guide rod is fixedly installed on the top of the inner sidewalls of the two horizontal plates and located between the two rotating rollers. Sliding blocks are threaded onto both ends of the outer peripheral surface of the bidirectional lead screw. Straight plates are fixedly installed on the outer top surfaces of the two sliding blocks and located between the two sets of several rotating rollers. At the same time, square blocks are movably sleeved on the outer peripheral surfaces of both ends of the guide rod through fixedly installed square blocks on the outer top surfaces of the two straight plates.

[0008] As a further technical solution of this utility model, one end of the bidirectional lead screw extends to the outer wall of one of the horizontal plates and a limiting plate is fixedly installed on the outer peripheral surface. The limiting plate is threadedly fixed to one of the horizontal plates by a positioning screw.

[0009] As a further technical solution of this utility model, the processing component includes a connecting plate disposed on the left side inside the two housings. An arc-shaped pressure plate is fixedly connected to the corresponding outer surfaces of the two connecting plates by bolts. At the same time, a threaded rod is rotatably connected at the center position of the opposite outer surfaces of the two connecting plates. One end of the two threaded rods extends to the opposite outer side walls of the two housings respectively, and a knob is fixedly installed on the outer peripheral surface. Meanwhile, a cutter is provided on the right side inside the two housings.

[0010] As a further technical solution of this utility model, sliding rods are fixedly installed on opposite outer surfaces of the two connecting plates and at both ends of the two threaded rods, and the opposite ends of the two pairs of sliding rods extend to opposite outer walls of the two housings respectively.

[0011] As a further technical solution of this utility model, electric push rods are fixedly installed on the opposite outer surfaces of the two housings, and the output ends of the two sets of electric push rods extend into the interior of the two housings and are fixedly connected to the two cutters.

[0012] This invention provides a convenient-to-operate surface coating equipment for cold-rolled steel sheets, which has the following advantages compared with the prior art:

[0013] 1. This design provides an easy-to-operate surface coating equipment for cold-rolled steel sheets. By using the cooperation of a knob and a threaded rod, the connecting plate and the arc-shaped pressure plate move relative to each other, moving away from or closer to each other, so that they come into contact with the upper and lower surfaces of the cold-rolled steel sheet. This allows the protective film on both sides of the cold-rolled steel sheet to adhere tightly, ensuring the processing effect of double-sided coating.

[0014] 2. This design provides a convenient cold-rolled steel sheet surface coating equipment. By using a bidirectional lead screw and guide rod, the straight plate can be driven to move relative to each other, thereby limiting the two ends of the cold-rolled steel sheet to prevent displacement and affecting the subsequent coating effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6This utility model provides a convenient operating technical solution for a cold-rolled steel sheet surface coating equipment: It includes a base frame 1, with horizontal plates 101 fixedly installed at both ends of the outer top surface of the base frame 1. Two horizontal plates 101 are symmetrically rotatably connected to each other with an array of rotating rollers 102. The ends of two groups of rotating rollers 102 extend to opposite outer walls of the two horizontal plates 101. A housing 103 is threadedly fixed to the right ends of the outer top and bottom surfaces of both horizontal plates 101. A support plate 104 is fixedly installed to the left ends of the outer top and bottom surfaces of one of the horizontal plates 101, and rotating rollers 105 are rotatably connected to the outer walls of both support plates 104. A coating roll is fitted onto the outer surface of the two rotating rollers 105. A processing component 2 for compacting and cutting double-sided coated steel sheets is provided inside the housings 103. The processing component 2 includes components disposed on both housings 103. 3. The connecting plate 201 on the left side inside the two connecting plates 201 is fixedly connected to the arc-shaped pressure plate 202 by bolts on the corresponding outer surfaces of the two connecting plates 201. At the same time, the threaded rods 203 are rotatably connected at the center of the opposite outer surfaces of the two connecting plates 201. One end of the two threaded rods 203 extends to the opposite outer walls of the two housings 103, and the outer surface of the two connecting plates 201 is fixedly installed with a knob 204. Meanwhile, the right side inside the two housings 103 is provided with a cutter 205. The opposite outer surfaces of the two connecting plates 201 and the two ends of the threaded rods 203 are fixedly installed with sliding rods 206. The opposite ends of the two pairs of sliding rods 206 extend to the opposite outer walls of the two housings 103. The opposite outer surfaces of the two housings 103 are fixedly installed with electric push rods 207. The output ends of the two sets of electric push rods 207 extend into the interior of the two housings 103 and are fixedly connected to the two cutters 205.In use, first, the corresponding coated rolls are respectively positioned and fitted onto the outer surfaces of the two rotating rollers 105 as needed. Then, the protective film is extended between the two sets of rotating rollers 102. Next, the cold-rolled steel sheet to be coated is placed between the two sets of rotating rollers 102. Then, the drive unit on the outer wall of the horizontal plate 101 is controlled and activated to drive the rotating rollers 102 to rotate synchronously, thereby moving the cold-rolled steel sheet. During the movement, the protective film adheres to the upper and lower surfaces of the cold-rolled steel sheet. When the coated cold-rolled steel sheet moves into the interior of the housing 103, the knobs 204 are turned to drive the threaded rod 203 to rotate, thereby allowing the connecting plate 201 to move. The curved pressure plates 202 move relative to each other, either moving away or closer, so that the two curved pressure plates 202 abut against the upper and lower surfaces of the cold-rolled steel sheet, thereby making the protective film tightly adhere to the upper and lower sides of the cold-rolled steel sheet. At the same time, since the curved pressure plates 202 are threadedly connected to the connecting plate 201, the corresponding curved pressure plates 202 can be replaced according to the size of the cold-rolled steel sheet, which has good flexibility of use. Then, the cold-rolled steel sheet with double-sided film is moved to the bottom of the cutter 205. The electric push rod 207 is controlled and activated to drive the cutter 205 to cut the protective film, thereby completing the double-sided film processing of the cold-rolled steel sheet.

[0027] Positioning components 3 are provided on the inner sidewalls of the two horizontal plates 101 corresponding to each other and located between the roller spacing of the two rotating rollers 102 to prevent the coated steel plate from shifting. The positioning components 3 include a bidirectional lead screw 301 rotatably connected to the bottom of the inner sidewalls of the two horizontal plates 101 and located between the roller spacing of the two rotating rollers 102. A guide rod 302 is fixedly installed on the top of the inner sidewalls of the two horizontal plates 101 and located between the roller spacing of the two rotating rollers 102. Sliding parts are threaded onto both ends of the outer peripheral surface of the bidirectional lead screw 301. A straight plate 304 is fixedly installed on the outer top surface of two sliding blocks 303 and between two sets of rotating rollers 102. Simultaneously, square blocks are movably fitted onto the outer peripheral surfaces of both ends of the guide rod 302 via fixedly installed square blocks on the outer top surface of the two straight plates 304. One end of the bidirectional lead screw 301 extends to the outer wall of one of the horizontal plates 101, and a limiting plate 305 is fixedly installed on its outer peripheral surface. The limiting plate 305 is threadedly fixed to one of the horizontal plates 101 by a positioning screw 306. Twisting the limiting plate 305 drives the bidirectional lead screw 301 to rotate, thereby driving the sliding blocks 303, carrying the straight plates 304, to move axially relative to each other with the assistance of the guide rod 302. This limits the ends of cold-rolled steel sheets of different sizes, preventing the cold-rolled steel sheets from shifting and affecting the subsequent coating effect.

[0028] The working principle of this utility model is as follows: During use, the corresponding coated rolls are respectively limited and sleeved on the outer surfaces of the two rotating rollers 105. The cold-rolled steel sheet to be coated is placed between the two sets of rotating rollers 102. Then, the limiting plate 305 is turned to drive the bidirectional lead screw 301 to rotate, which drives the sliding block 303 to move axially relative to the straight plate 304, thereby limiting the two ends of the cold-rolled steel sheet.

[0029] At the same time, the drive unit is activated to drive the rotating roller 102 to rotate synchronously, thereby moving the cold-rolled steel plate, and during the movement, the protective film is attached to the upper and lower surfaces of the cold-rolled steel plate.

[0030] At the same time, when the coated cold-rolled steel sheet moves into the interior of the housing 103, the knobs 204 are turned to drive the threaded rod 203 to rotate, so that the connecting plate 201 and the arc-shaped pressure plate 202 move relative to each other, so that the two arc-shaped pressure plates 202 abut against the upper and lower surfaces of the cold-rolled steel sheet, and the protective film is tightly attached to the upper and lower sides of the cold-rolled steel sheet.

[0031] Finally, the electric push rod 207 is activated to drive the cutter 205 to cut the protective film, thereby completing the double-sided film coating process of the cold-rolled steel sheet.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
