Description

Technical Field

[0001] This utility model relates to the field of stainless steel coil processing technology, and in particular to a stainless steel coil wire drawing machine. Background Technology

[0002] In the field of stainless steel coil processing, wire drawing can give the surface of stainless steel coils specific texture effects or improve surface properties. It is a key process to improve the surface quality and aesthetics of products.

[0003] Traditional wire drawing equipment often uses a fixed structure, making it difficult to dynamically adjust the contact force between the grinding belt and the surface of the coil according to actual processing needs. For example, when processing stainless steel coils of different thicknesses or materials, a fixed contact force design can lead to uneven wire drawing results, with some areas potentially being over- or under-ground, directly affecting the stability of product quality.

[0004] In addition, during the conveying process, the roll material is prone to vibration or displacement, which can cause deviation in the contact position with the polishing belt. This can easily lead to inconsistent brushing effects on different parts of the roll material surface, affecting the product's aesthetics.

[0005] To address the aforementioned problems, this utility model document proposes a stainless steel coil drawing machine. Utility Model Content

[0006] The purpose of this invention is to solve the shortcomings of existing technologies, such as the difficulty in dynamically adjusting the contact and grinding force between traditional wire drawing equipment and products, uneven wire drawing effect, easy conveying deviation, and impact on quality stability and product aesthetics. Therefore, a stainless steel coil wire drawing machine is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: A stainless steel coil drawing machine, comprising: A base, on top of which a conveyor belt is provided; A housing is fixedly installed on the top of the base, and the housing has openings on both sides. The conveyor belt is located inside the housing and extends through the openings at both ends. The wire drawing assembly is provided in two sets. Each set of the wire drawing assembly includes a rotating roller I, a rotating roller II and a polishing belt. The rotating roller I and the rotating roller II are arranged vertically, with the rotating roller I located below the rotating roller II. The polishing belt is driven and sleeved between the rotating roller I and the rotating roller II. An adjustment assembly, located between two sets of wire drawing assemblies, includes a lifting bracket, a servo motor, a ball screw, an extension plate, a limiting groove, and a positioning post. The extension plate is fixed to the wire drawing assembly and has an inclined limiting groove inside. The positioning post is fixed to both ends of the lifting bracket and is slidably connected to the limiting groove. The ball screw is rotatably mounted on the housing, and the servo motor drives and connects to the ball screw. The lifting bracket is fixedly sleeved on the outer wall of the ball nut of the ball screw. The servo motor drives the ball screw to rotate, which in turn raises and lowers the lifting bracket. The positioning column slides in the limit groove, changing the tilt angle of the wire drawing assembly, thereby adjusting the distance between the rotating roller I and the roll material on the conveyor belt.

[0008] In one possible design, the wire drawing assembly further includes a rotating plate I and a rotating plate II, with the two ends of the rotating roller I and the rotating roller II respectively rotatably connected to the rotating plate I and the rotating plate II, and the top ends of the rotating plate I and the rotating plate II rotatably connected to the inner wall of the housing; a drive motor is mounted on the rotating plate I, and the output shaft of the drive motor is connected to the rotating roller II.

[0009] In one possible design, the extension plate of the adjustment component is fixed to the rotating plate II, and the limiting groove is inclinedly opened on the extension plate.

[0010] In one possible design, a pressing mechanism is also included, located within the housing near the opening, the pressing mechanism comprising a pressure roller for pressing the roll on the conveyor belt.

[0011] In one possible design, the pressing mechanism further includes a fixed plate, a fixed bracket, a guide rod, and a spring; the fixed plate is fixed to the housing, a pressure roller is arranged below the fixed bracket, the guide rod slides through the fixed plate, and the spring is sleeved on the guide rod so that the pressure roller is in close contact with the conveyor belt.

[0012] In one possible design, an elastic sheet is also included, positioned above the conveyor belt, for guiding and positioning the roll.

[0013] In one possible design, the elastic sheet has two sets, one set located at the housing inlet and the other set located between the two sets of wire drawing assemblies, both of which are inclined.

[0014] In one possible design, the drive motor drives the rotating roller II to rotate, which in turn drives the grinding belt to grind the surface of the roll material.

[0015] In one possible design, two sets of wire drawing components are arranged in series, and the roll material passes through two sets of grinding belts in sequence to complete double grinding.

[0016] In this application, during use, the stainless steel coil is conveyed by a conveyor belt and enters the housing through an opening at one end. Before entering the housing, two elastic tabs located at one end of the housing guide the stainless steel coil, ensuring that the coil moves along a preset path.

[0017] The conveyor belt operates continuously, feeding the stainless steel coils to the pressing mechanism. The pressure rollers in the pressing mechanism, under the elastic force of springs, press firmly against the top of the conveyor belt, providing stable pressure to the passing stainless steel coils and ensuring stable transport of the coils.

[0018] The stainless steel coil continues to move until it reaches the first set of wire drawing components. At this point, the drive motor starts, and the output shaft drives the rotating roller II to rotate. The rotating roller II drives the grinding belt to rotate through the transmission relationship with the rotating roller I. The rotating grinding belt contacts the surface of the stainless steel coil, performing preliminary grinding on the coil to complete the corresponding wire drawing process.

[0019] After initial polishing, the stainless steel coil is repositioned by the elastic sheet between the two sets of wire drawing components to ensure accurate positioning when entering the second set of wire drawing components.

[0020] Based on the processing requirements of stainless steel coils, the contact force between the grinding belt and the surface of the stainless steel coil can be adjusted via a servo motor. The servo motor drives the ball screw to rotate, causing the lifting bracket, which is sleeved on the outer wall of the ball screw sleeve, to move up and down. The positioning pins at both ends of the lifting bracket slide within the limiting grooves of the extension plate. Due to the inclined setting of the limiting grooves, the vertical movement of the lifting bracket can push rotating plate II and rotating plate I to rotate around the connection point with the inner wall of the housing, thereby changing the tilt angle of the two sets of wire drawing components. The change in tilt angle can change the distance between rotating roller I and the stainless steel coil, thereby adjusting the contact force between the grinding belt and the surface of the stainless steel coil, and thus adjusting the wire drawing depth of the stainless steel coil to adapt to different processing requirements.

[0021] The drive motor in the second wire drawing assembly also drives the corresponding rotating roller II to rotate, causing the grinding belt of that assembly to operate and further grind the stainless steel coil. During this process, the grinding belts of both wire drawing assemblies work continuously to complete the wire drawing treatment on the surface of the stainless steel coil.

[0022] During the processing, operators can observe the internal processing conditions through an observation window on one side of the casing to ensure that the equipment operates normally and the processing results meet the requirements.

[0023] After being processed by two sets of wire drawing components, the stainless steel coil can continue to be conveyed by the conveyor belt and finally sent out from the opening at the other end of the shell, completing the entire wire drawing process.

[0024] Beneficial Effects: In this utility model, the stainless steel coil drawing machine uses a servo motor to drive a ball screw, which in turn drives the lifting bracket to move vertically. Combined with an inclined limiting groove and positioning column structure, the vertical motion can be converted into an adjustment of the tilt angle of the drawing assembly. This design allows for precise control of the distance between the rotating roller I and the coil surface, thereby dynamically adjusting the contact force of the grinding belt to adapt to the processing needs of coils of different thicknesses or materials, significantly improving the uniformity of drawing depth and the stability of product quality. In this utility model, the stainless steel coil drawing machine adopts a spring-driven pressure roller structure for the pressing mechanism, which ensures that the coil is always in close contact with the conveyor belt during the conveying process, effectively suppressing vibration and deviation; with the inclined guide design of the elastic sheet, the coil can automatically correct its position before entering the drawing assembly, ensuring the contact position accuracy with the grinding belt and avoiding the problem of local over-grinding or under-grinding caused by position deviation. In this utility model, the stainless steel coil wire drawing machine features an integrated design between the adjustment component and the wire drawing component, which supports online adjustment. The contact force can be adjusted without stopping the machine, significantly shortening the equipment debugging time. The series arrangement of the two sets of wire drawing components enables double polishing of the coil surface, and the preset wire drawing effect can be achieved in a single pass, effectively improving the production and processing efficiency of the product. In this invention, the equipment uses a servo motor and ball screw to drive the lifting bracket to move vertically, and a linkage tilting limit groove structure to precisely control the distance between the rotating roller I and the roll material. This dynamically adjusts the contact force between the grinding belt and the product surface, improving the uniformity of the drawing depth and adaptability to different roll materials. The spring pressure roller and elastic sheet work together to ensure stable and accurate roll material conveying, avoiding deviations during conveying that could affect the drawing effect. The adjustment component supports adjusting the contact force during operation, and combined with the series-connected double-set drawing components, it achieves efficient and uniform double grinding, significantly improving production efficiency and product quality stability.

[0027] 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.

[0028] In one embodiment: Refer to Figure 1-6 A wire drawing machine includes: a base 1, a housing 2, a conveyor belt 3, a wire drawing assembly, an adjusting assembly, a pressing mechanism, and an elastic sheet 4.

[0029] In this embodiment, the base 1 serves as the supporting foundation for the entire equipment. A conveyor belt 3 is mounted on its top via a support frame to transport the stainless steel coil to be processed. A housing 2 is fixedly installed on the top of the base 1. Openings are provided on both sides of the housing 2 near the bottom. The conveyor belt 3 is located inside the housing 2, and both ends of the conveyor belt 3 extend outside the housing 2 through the openings to facilitate the entry and exit of the stainless steel coil.

[0030] In this embodiment, two sets of wire drawing assemblies are provided. Each set of wire drawing assemblies includes a rotating roller I5, a rotating roller II6, a rotating plate I13, a rotating plate II14, and a drive motor 15. The rotating rollers I5 and II6 are arranged vertically, with I5 located below II6. A common grinding belt 7 is sleeved between them. The grinding belt 7 is used to grind and polish the stainless steel coil to be processed, thus completing the corresponding wire drawing process. The two ends of the rotating rollers I5 and II6 are rotatably connected to the adjacent rotating plates I13 and II14 on their closest sides. The positions of the rotating plates I13 and II14 near their top ends are rotatably connected to the inner wall of one side of the adjacent housing 2. A mounting groove is provided on the top of the rotating plate I13, and the drive motor 15 is fixedly installed in the mounting groove. One end of the output shaft of the drive motor 15 is fixedly connected to one end of the rotating roller II6, providing rotational power to the rotating roller II6, thereby driving the grinding belt 7.

[0031] In this embodiment, the adjustment assembly is located between two sets of wire drawing assemblies and includes two extension plates 16, a ball screw 18, a servo motor 19, and a lifting bracket 20. The two extension plates 16 are respectively fixedly installed on the sides of the two rotating plates II 14 that are close to each other. Each extension plate 16 has a corresponding limiting groove 17 inside, and both limiting grooves 17 are inclined. The lifting bracket 20 is located between the two extension plates 16, and positioning posts 21 are fixedly installed at both ends of the bracket. Both positioning posts 21 are slidably connected to the inner wall of the limiting groove 17. A ball screw 18 is rotatably installed on one side of the inner wall of the housing 2 via a bracket. A servo motor 19 is installed at the top of the ball screw 18. The servo motor 19 is fixedly connected to one side of the inner wall of the housing 2 via a bracket. One end of the output shaft of the servo motor 19 is fixedly connected to the top of the ball screw 18. The lifting bracket 20 is fixedly sleeved on the outer wall of the ball sleeve of the ball screw 18. When the servo motor 19 is started, it can drive the ball screw 18 to rotate precisely, which in turn can drive the lifting bracket 20 to move up and down precisely. Since the positioning column 21 slides in the limiting groove 17 and the limiting groove 17 is set at an angle, the up and down movement of the lifting bracket 20 can adjust the tilt angle of the two sets of wire drawing components, thereby realizing the adjustment of the distance between the two rotating rollers I5 and the stainless steel coil to be processed.

[0032] In this embodiment, four elastic plates 4 are arranged above the conveyor belt 3, in pairs. Two elastic plates 4 from one group are located at one end of the housing 2, while two elastic plates 4 from the other group are located inside the housing 2 and between the two wire drawing assemblies. Both elastic plates 4 in the same group are fixedly connected to the inner wall of the adjacent housing 2 via brackets, and both elastic plates 4 in the same group are inclined. Their function is to complete the conveying and positioning of the stainless steel coil, ensuring that the stainless steel coil remains in the correct position during conveying.

[0033] This application can be used in the field of stainless steel coil processing technology, or in other fields applicable to this application.

[0034] In another embodiment: Reference Figure 1 , 3 4. A stainless steel coil drawing machine, which is applied to the field of stainless steel coil processing technology; In this embodiment, two sets of pressing mechanisms are provided inside the housing 2, and the two sets of pressing mechanisms are located near the openings at both ends of the housing 2. Each pressing mechanism includes a fixed plate 11, a fixed bracket 9, a pressure roller 8, a guide rod 10, and a spring 12. The fixed plate 11 is fixedly installed on the inner wall of one side of the housing 2. The fixed bracket 9 is provided below the fixed plate 11, and the pressure roller 8 is provided below the fixed bracket 9. The pressure roller 8 is rotatably connected to the inner wall of the fixed bracket 9, and the pressure roller 8 cooperates with the conveyor belt 3. Three guide rods 10 are fixedly installed on the top of the fixed bracket 9. The top ends of the three guide rods 10 slide through the fixed plate 11. Springs 12 are sleeved on the outer walls of the three guide rods 10. The top ends of the multiple springs 12 are fixedly connected to the bottom of the fixed plate 11 through spring 12 seats, and the bottom ends of the multiple springs 12 are fixedly connected to the top of the fixed bracket 9 through spring 12 seats. Under the action of spring 12, the pressure roller 8 can be kept close to the top of the conveyor belt 3, thereby pressing the stainless steel coil in the conveying process and preventing the stainless steel coil from jumping during the conveying process.

[0035] In this embodiment, an observation window is provided on one side of the housing 2, through which the interior of the housing 2 can be observed so as to understand the operation of the equipment and the processing status of the stainless steel coil in a timely manner.

[0036] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive motor 15 and the servo motor 19 are conventional methods or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0037] The working principle and usage process of this technical solution are as follows: During use, the stainless steel coil is conveyed by the conveyor belt 3 and enters the housing 2 through an opening at one end. Before entering the housing 2, two elastic plates 4 located at one end of the housing 2 guide the stainless steel coil, ensuring that the coil moves along a preset path.

[0038] The conveyor belt 3 operates continuously, feeding the stainless steel coil to the pressing mechanism. The pressure roller 8 in the pressing mechanism is pressed tightly against the top of the conveyor belt 3 under the elastic force of the spring 12, forming a stable pressure on the passing stainless steel coil to ensure stable conveying of the coil.

[0039] The stainless steel coil continues to move until it reaches the first set of wire drawing components. At this point, the drive motor 15 starts, and its output shaft drives the rotating roller II 6 to rotate. The rotating roller II 6 drives the grinding belt 7 to rotate through the transmission relationship with the rotating roller I 5. The rotating grinding belt 7 contacts the surface of the stainless steel coil, performing preliminary grinding on the coil to complete the corresponding wire drawing process.

[0040] After the initial grinding is completed, the stainless steel coil is repositioned by the elastic sheet 4 between the two sets of wire drawing components to ensure accurate positioning when entering the second set of wire drawing components.

[0041] According to the processing requirements of stainless steel coils, the contact force between the grinding belt 7 and the surface of the stainless steel coil can be adjusted by the servo motor 19. The servo motor 19 drives the ball screw 18 to rotate, causing the lifting bracket 20, which is sleeved on the outer wall of the ball sleeve of the ball screw 18, to move up and down. The positioning pins at both ends of the lifting bracket 20 slide within the limiting groove 17 of the extension plate 16. Due to the inclined setting of the limiting groove 17, the vertical movement of the lifting bracket 20 can push the rotating plate II 14 and the rotating plate I 13 to rotate around the connection point with the inner wall of the housing 2, thereby changing the tilt angle of the two sets of wire drawing components. The change of tilt angle can change the distance between the rotating roller I 5 and the stainless steel coil, thereby adjusting the contact force between the grinding belt 7 and the surface of the stainless steel coil, and thus adjusting the wire drawing depth of the stainless steel coil to adapt to different processing requirements.

[0042] The drive motor 15 in the second wire drawing assembly also drives the corresponding rotating roller II 6 to rotate, causing the grinding belt 7 of this assembly to operate and further grind the stainless steel coil. During this process, the grinding belts 7 of both wire drawing assemblies work continuously to complete the wire drawing treatment on the surface of the stainless steel coil.

[0043] During the processing, the operator can observe the internal processing through the observation window on one side of the housing 2 to ensure that the equipment operates normally and the processing effect meets the requirements.

[0044] After being processed by the two sets of wire drawing components, the stainless steel coil can continue to be conveyed by the conveyor belt 3 and finally sent out from the opening at the other end of the housing 2, completing the entire wire drawing process.

[0045] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
