Description

Technical Field

[0001] This invention belongs to the technical field of steel wool processing equipment, specifically relating to a steel wool drawing machine. Background Technology

[0002] Steel wool is used for everyday tasks such as washing and scrubbing dishes, and is a frequently consumed household item. There are many types of steel wool, including a type with a ring-shaped design, such as... Figure 6 As shown, a semi-finished product, a ring-shaped steel wire mesh, is formed by continuous rolling and turning. The resulting ring-shaped semi-finished product generally has a loose structure and excessive deformation, making it inconvenient for practical use. Therefore, it usually requires subsequent tightening to reduce the outer diameter of the steel wire ball, making the structure compact and ultimately forming a finished product with a regular shape and uniform appearance. Currently, the tightening of the semi-finished ring-shaped steel wire balls is generally done manually, which is slow, inefficient, and labor-intensive. Summary of the Invention

[0003] The present invention aims to overcome the defects of the prior art and solve the problems of slow operation, low production efficiency, high labor costs and inconsistent shape of existing ring steel wool production, which relies on manual wire pulling and tightening.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a steel wool drawing machine, comprising a conveying mechanism for feeding semi-finished steel wool and a tightening mechanism for drawing and tightening the semi-finished steel wool; the tightening mechanism includes a support plate, a pressure plate, a hook assembly, and a shearing assembly; the pressure plate is located above the support plate and can move up and down relative to the support plate; the hook assembly includes multiple hooks, which can move up and down through a notch in the middle of the pressure plate, and the multiple hooks can also rotate circumferentially as a whole; the shearing assembly is located above the pressure plate and is used to cut off the excess steel wire ends above the knotted part of the tightened steel wool; the conveying mechanism feeds the semi-finished steel wool onto the support plate.

[0005] In the above technical solution, the conveying mechanism realizes the automatic conveying, precise feeding and station limiting of the steel wool semi-finished product. The tightening mechanism automatically completes the entire process of positioning and pressing the steel wool semi-finished product, pulling up and twisting the steel wire at the center of the steel wool, and cutting off the excess steel wire ends above the twisted knot. Finally, the outer diameter of the steel wool is reduced to make its structure compact and form a finished product with a regular shape and uniform appearance, realizing fully automated industrial production.

[0006] Furthermore, the crochet assembly also includes a crochet base, on which the crochet hook is mounted. The rotation of the crochet base is driven by a tightening motor, and the up-and-down movement of the crochet base is pushed by a first cylinder.

[0007] Furthermore, a vertical mounting plate is provided for the tightening motor, and a first vertical guide rail is provided on the vertical mounting plate. A slide block is slidably mounted on the first vertical guide rail. The slide block is connected to the piston rod of the first cylinder, and the tightening motor is mounted on the slide block.

[0008] Furthermore, the hook assembly also includes a bidirectional screw, which is rotatably mounted on the hook seat. The threads at both ends of the bidirectional screw have opposite directions, and each end of the bidirectional screw is threaded with a hook, so that the two hooks are symmetrically mounted on the bidirectional screw for radial position adjustment. The hook is vertically positioned and has a barb structure at its bottom. A square guide block is provided at the top of the hook. A strip-shaped guide groove matching the square guide block is opened on the hook seat, and the square guide block is slidably engaged in the strip-shaped guide groove.

[0009] Furthermore, the pressure plate has an annular structure, including an upper plate and a lower plate spaced apart vertically, the upper plate and the lower plate being connected by a connecting rod; a second vertical guide rail is provided corresponding to the pressure plate, a slider is slidably mounted on the second vertical guide rail, a connecting frame is mounted on the slider, the pressure plate is mounted on the connecting frame, and a second cylinder is also included, the piston rod of the second cylinder being connected to the connecting frame, the shearing assembly being mounted on the connecting frame.

[0010] Furthermore, the shearing assembly includes a connecting seat connected to the connecting frame, an insertion guide rail is mounted on the bottom of the connecting seat, an insertion slider is slidably mounted on the insertion guide rail, a pneumatic shear is mounted on the insertion slider, and a third cylinder for driving the insertion slider to slide horizontally is mounted on the connecting seat.

[0011] Furthermore, the conveying mechanism includes a conveyor belt surrounding the frame and baffles on both sides of the conveyor belt. The baffles have a feeding inlet facing the material support plate, and a photoelectric sensor is provided at the feeding inlet. A scraper that can slide laterally is provided above the conveyor belt, and the scraper is driven by a scraper cylinder. A retractable baffle plate is provided at the tail end of the material support plate, and the baffle plate is driven to extend and retract by a baffle cylinder installed on the frame.

[0012] Furthermore, an adjustment knob is installed at the end of the bidirectional screw. The adjustment knob is exposed on the outside of the hook seat and is used to manually rotate the bidirectional screw to adjust the distance between the two hooks, so as to adapt to steel wool balls of different sizes.

[0013] Furthermore, the pneumatic scissors are connected to an air compressor via a solenoid valve, and the photoelectric sensor, each cylinder, tightening motor, and air compressor are all electrically connected to the equipment controller.

[0014] The conveying mechanism uses a conveyor belt to continuously transport steel wool, and baffles limit the material to prevent it from shifting during transport. Photoelectric sensors at the feeding inlet can accurately detect the material in place, and the scraper driven by the scraper cylinder automatically pushes the steel wool to be processed onto the support plate. The retractable baffle plate at the end of the support plate can limit the steel wool during processing and retract after processing, realizing automatic discharge of finished products and fully automated linkage operation.

[0015] The beneficial technical effects of this invention are as follows: This invention integrates automatic feeding, station limiting, automatic wire pulling and tightening, automatic wire cutting, and automatic material discharge functions, thereby automatically realizing the wire pulling and tightening operation of steel wool, completely eliminating the manual operation mode, greatly reducing the intensity of manual labor, effectively reducing production labor costs, improving production efficiency, and achieving a finished steel wool product structure with regular shape and uniform appearance; moreover, the hook assembly of this invention can adaptively adjust the hook spacing, which can adapt to the processing of various specifications and sizes of annular steel wool, making the equipment highly versatile and applicable to a wide range of fields.

[0019] The present invention will be specifically described below through embodiments, which are only used to further illustrate the present invention and should not be construed as limiting the scope of protection of the present invention.

[0020] like Figure 1 — Figure 5 As shown, this embodiment discloses a steel wool drawing machine, including a frame, on which a conveying mechanism 100 and a tightening mechanism 200 are installed. The conveying mechanism is used to continuously convey loose steel wool to be processed and accurately push the material to the processing station of the tightening mechanism. The tightening mechanism completes the pressing, tightening and wire cutting of the steel wool, realizing fully automatic operation.

[0021] The tightening mechanism includes a material support plate 1, a hook assembly 2, a pressure plate 3, pneumatic shears, and a vertical mounting plate 5. The material support plate 1 is horizontally mounted on the side wall of the frame, serving as a platform for processing steel wool. The vertical mounting plate 5 is vertically mounted on the frame and located behind the material support plate 1. A first vertical guide rail 6 is mounted on the upper part of the vertical mounting plate 5, and a slide block 7 is slidably mounted on the first vertical guide rail 6. A first cylinder 8 is mounted on the top of the vertical mounting plate 5, and the piston rod of the first cylinder 8 is connected to the slide block 7, which can drive the slide block 7 to slide vertically up and down along the first vertical guide rail 6. A tightening motor 9 is mounted on the slide block 7, with the output shaft of the tightening motor 9 pointing vertically downwards. The bottom end of the output shaft is connected to the hook assembly 2.

[0022] The hook assembly 2 includes a hook seat 10, a bidirectional screw 11, and two symmetrically arranged hooks 12. The top surface of the hook seat 10 is mounted to the output shaft of the tightening motor 9. The bidirectional screw 11 is horizontally rotatably mounted on the hook seat 10, with the threads at the left and right ends of the bidirectional screw 11 rotating in opposite directions. One end of the bidirectional screw 11 extends to the outside of the hook seat 10 and is fitted with an adjustment knob 34 for easy manual adjustment. The two hooks 12 are vertically symmetrically arranged, each with a square guide block 13 at its top. The bottom surface of the hook seat 10 has two parallel strip-shaped guide grooves 14 corresponding to each other. The square guide blocks 13 slide and engage inside the strip-shaped guide grooves 14 to limit the sliding of the hooks 12. The middle parts of the two hooks 12 are threaded into the two ends of the bidirectional screw 11. Rotating the adjustment knob 34 drives the bidirectional screw 11 to rotate, which can drive the two hooks 12 to slide synchronously relative to each other or in opposite directions, achieving stepless adjustment of the distance between the hooks 12 and adapting to different sizes of steel wool. The bottom of the crochet hook 12 is equipped with an acute-angled barb, which can effectively hook the center wire of the steel wool ball and prevent it from twisting and slipping.

[0023] A second vertical guide rail 18 is installed at the lower part of the vertical mounting plate 5. A slider 19 is slidably mounted on the second vertical guide rail 18. A connecting frame 20 is located on the outer side of the slider 19. A second cylinder 21 is installed on the vertical mounting plate 5. The piston rod of the second cylinder 21 is connected to the connecting frame 20, which can drive the connecting frame 20 and the slider 19 to rise and fall vertically along the second vertical guide rail 18. A pressure plate 3 is installed at the front end of the connecting frame 20. The pressure plate 3 has a circular structure and consists of an upper plate 15, a lower plate 16, and multiple connecting rods 17. The upper plate 15 and the lower plate 16 are arranged parallel to each other vertically and spaced apart. The edges are connected as one piece by the connecting rods 17. The double-layer hollow structure can avoid the lifting and rotating motion of the hook 12, while also stably pressing the end face of the steel wool ball. The inner diameter of the upper plate 15 is larger than the outer diameter of the maximum adjustment distance of the hook 12, ensuring that the hook can pass smoothly through the pressure plate 3.

[0024] A shearing assembly 4 is installed at the bottom of the connecting frame 20. The shearing assembly 4 includes a connecting seat 22 connected to the connecting frame 20. An insertion guide rail 23 is installed at the bottom of the connecting seat 22. An insertion slider 24 is slidably mounted on the insertion guide rail 23. A pneumatic shear 41 is installed on the insertion slider 24. A third cylinder 25 for driving the insertion slider 24 to slide horizontally is installed on the connecting seat 22. The third cylinder 25 is installed on the upper part of the connecting seat 22. The piston rod of the third cylinder 25 is connected to the insertion slider 24 or the pneumatic shear 41 through a transmission plate. It can drive the insertion slider 24 to slide horizontally along the insertion guide rail 23, thereby driving the pneumatic shear 41 to horizontally insert into the gap between the upper plate 15 and the lower plate 16 to complete the wire cutting operation. The pneumatic shear 41 is connected to an air compressor through a solenoid valve to provide power for the cutting action.

[0025] The conveying mechanism includes a conveyor belt 26, baffles 27, scrapers 30, and retaining plates 32. The conveyor belt 26 is mounted around the frame for continuously conveying steel wool to be processed. Baffles 27 are symmetrically installed on both sides of the conveyor belt 26 to prevent material conveying deviation. A feeding inlet 28 is provided on the baffle 27 corresponding to the position of the support plate 1. A photoelectric sensor 29 is installed at the feeding inlet 28 to detect passing steel wool. A scraper 30 is horizontally arranged above the conveyor belt 26. The scraper 30 is driven laterally by a scraper cylinder 31 mounted on the frame, which pushes the detected steel wool through the feeding inlet 28 onto the support plate 1.

[0026] A baffle plate 32 is slidably installed at the tail end of the material support plate 1. A baffle cylinder 33 is installed on the frame and its piston rod is connected to the baffle plate 32, which can drive the baffle plate 32 to extend and retract vertically. During steel wool processing, the baffle plate 32 extends out of the end face of the material support plate 1 to limit the steel wool and prevent processing deviation. After processing is completed, the baffle plate 32 retracts, and the new steel wool pushed in later can push the finished steel wool out of the station, realizing automatic material discharge.

[0027] The equipment is equipped with a controller, photoelectric sensor 29, first cylinder 8, second cylinder 21, third cylinder 25, scraper cylinder 31, stop cylinder 33, tightening motor 9, and solenoid valves, all of which are electrically connected to the controller to achieve fully automated linkage control.

[0028] The specific working process of this equipment is as follows: Loose steel wool balls to be processed are continuously conveyed by conveyor belt 26. After photoelectric sensor 29 detects that the steel wool balls have reached the correct position, it sends a feedback signal to the controller. The controller controls scraper cylinder 31 to drive scraper 30 to move laterally, pushing the steel wool balls through feeding inlet 28 onto the support plate 1. At the same time, blocking cylinder 33 drives blocking plate 32 to extend and limit the steel wool balls. Subsequently, second cylinder 21 drives pressure plate 3 to move down, pressing the upper end face of the steel wool balls to complete the positioning. First cylinder 8 drives slide 7 to move down, causing hook 12 of hook assembly 2 to pass through the hole in pressure plate 3 and insert into the steel wool balls. The steel wool ball is centered; then the first cylinder 8 drives the hook 12 to rise, passing over the pressure plate 3. The hook hook hooks the center wire through the bottom barb, pulling up the center of the steel wool ball and tightening it. At this time, the tightening motor 9 starts, driving the hook 12 to rotate. The bottom barb hooks the center wire and twists it, causing the steel wool ball to continuously contract and tighten from the outside to the inside. After tightening is completed, the tightening motor 9 stops. The third cylinder 25 drives the pneumatic shears 41 to be horizontally inserted between the upper plate 15 and the lower plate 16 of the pressure plate 3, cutting off the excess steel wire brought out by the hook 12 barb. After the wire is cut, the pneumatic shears reset. Figure 7 As shown, a knot is formed in the center of the steel wool, keeping the steel wool in a tight state. The pressure plate 3 rises and resets; the baffle plate 32 retracts, and the next steel wool to be processed is pushed to the support plate 1 by the scraper 30. At the same time, the finished steel wool is pushed out of the station, and the continuous processing is completed in a cycle.
