Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, and in particular to a continuous conveying device for sheet metal. Background Technology

[0002] In the production and processing of sheet materials (such as wood-based panels, metal panels, and stone panels), continuous conveying is a crucial link in ensuring production efficiency. It requires stable, efficient, and damage-free transfer of the sheets to connect with subsequent processes such as cutting, sanding, and coating. Currently, commonly used continuous conveying devices for sheet materials in the industry mainly include roller conveyors, belt conveyors, and chain conveyors.

[0003] Roller conveyors, due to their strong load-bearing capacity and suitability for medium and heavy-duty sheet metal, are widely used in various sheet metal production lines. However, they suffer from the following drawbacks in actual use: First, the roller surface easily accumulates debris, dust, and other impurities generated during sheet metal processing. Long-term accumulation can lead to slippage, deviation, or even scratches on the sheet metal surface during transport, affecting product quality. Second, existing cleaning mechanisms for rollers mostly employ a method of contacting a fixed brush with the rotating roller. However, after prolonged use, the brush itself accumulates impurities. If not cleaned promptly, this reduces the cleaning effect on the roller and may even cause secondary contamination. Therefore, a continuous sheet metal conveying device needs to be designed.

[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0005] This utility model provides a continuous conveying device for sheet metal to solve the problem that impurities easily accumulate on the rollers of roller conveyors, causing damage to the sheet metal, and that the fixed brush cleaning mechanism is also prone to impurities, reducing efficiency or even causing secondary pollution.

[0006] The present invention adopts the following technical solution: a continuous conveying device for sheet metal, mainly comprising a roller conveyor, the roller conveyor having two sets of frames, with multiple sets of roller shafts arranged between the two sets of frames and stepped portions extending outward from the mutually distant sides of the frames; a cleaning assembly connected to the two sets of frames, the cleaning assembly including a cleaning part arranged on the stepped portion for cleaning the roller shafts, the cleaning part having a cleaning brush, and a shaking part arranged on the cleaning part for shaking the cleaning brush to remove impurities; and a limiting assembly arranged on the mutually close sides of the two sets of frames.

[0007] Furthermore, the cleaning unit includes guide rods fixed to two sets of stepped portions and extending through them. The guide rods are trapezoidal, and one end of each set of guide rods is connected to a support plate. A fixed seat slides between the two sets of guide rods. The cleaning brush is fixed between the two fixed seats by fasteners. The cleaning brush is arranged parallel to the roller shaft portion, and a through groove is provided on the stepped portion for the fixed seat to pass through.

[0008] Furthermore, the cleaning brush has a brush shaft that movably passes through the frame. The frame has an open waist groove. The shaking part includes a support shaft fixed to the bottom of the fixed seat. The support shaft movably passes through a support plate. A spring is sleeved on the support shaft. One end of the spring is connected to the bottom surface of the fixed seat, and the other end is connected to the support plate.

[0009] Furthermore, a rotating wheel is fixed at one end of the support shaft that movably passes through the support plate.

[0010] Furthermore, the limiting component includes two sets of mounting seats symmetrically arranged along the center line of the waist groove. Each mounting seat has a protrusion, which is a hollow columnar structure. The two sets of protrusions have an opening at their adjacent ends, and a convex ball is provided at the opening. The convex ball is connected to the inner wall of the protrusion by a spring, and there is a gap between the two sets of convex balls.

[0011] Furthermore, a concave protective cover is fixed to the side of the frame that is far apart from each other.

[0012] Furthermore, the elastic force of the second spring is greater than that of the first spring.

[0013] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0014] A continuous sheet metal conveying device utilizes a cleaning component with a cleaning brush that contacts the roller shaft to promptly remove debris, dust, and other impurities generated during sheet metal processing. This prevents long-term accumulation of impurities that could cause slippage, misalignment, or even scratches on the sheet metal surface during conveying. Simultaneously, a vibrating component on the cleaning component shakes the cleaning brush, removing impurities adhering to the brush itself. This prevents the brush from reducing its cleaning effectiveness on the roller shaft due to impurities and avoids secondary contamination of the roller shaft. The limiting component further optimizes the working state of the cleaning brush, maintaining a suitable gap between the brush and the roller shaft while cleaning its own impurities. This ensures more thorough cleaning without re-contaminating the roller shaft, thus improving the overall cleaning reliability and conveying stability of the device. Attached Figure Description

[0023] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0024] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1-3 As shown in the figure, the present invention provides a continuous sheet material conveying device, including a roller conveyor 1. The roller conveyor 1 is used to realize the continuous conveying operation of sheet material. The roller conveyor 1 includes two sets of frames 11, which are connected and supported by a support frame 12 on the bottom surface of the frames 11. Multiple sets of roller shafts 15 are arranged between the two sets of frames 11 and bearings. The roller shafts 15 are used to contact the sheet material. The sheet material is placed on the roller shafts 15 and conveyed as the roller shafts 15 rotate.

[0026] A drive unit for driving multiple sets of roller shafts 15 to rotate is fixed on the side of a set of frames 11. The drive unit includes a gearbox 14 fixed on the side of a set of frames 11. A drive motor 13 is fixed on the side of the gearbox 14. The gearbox 14 consists of a bevel gear set, an input shaft and an output shaft. The input shaft is fixed to the output end of the drive motor 13 through a coupling. The output shaft is fixed to a set of roller shafts 15. Thus, the power of the drive motor 13 is transmitted to the roller shafts 15 through the gearbox 14. A sprocket 16 is fixed at both ends of the remaining roller shafts. A sprocket 17 is provided on the side bearing of a set of frames 11. A guide rail 19 is fixed on the side of a set of frames 11 below the sprocket 16. A chain 18 is sleeved on the guide rail 19.

[0027] In actual operation, the chain 18 moves along the guide rail 19, maintaining good motion stability. The chain 18 is connected to the teeth of the second sprocket 17 through chain links. At the same time, the first sprocket 16 of the roller shaft 15 meshes with the second sprocket 17. Furthermore, a support sprocket 110 is provided on the side bearing of a set of frames 11 to support the chain 18 and mesh with it. The support sprocket 110 can support and guide the chain 18, preventing the chain 18 from sagging or deviating, ensuring stable and reliable meshing transmission between the first sprocket 16, the second sprocket 17, and the chain 18, and ensuring the synchronous rotation of the roller shaft 15, thereby achieving smooth and continuous conveying of the sheet material.

[0028] Reference Figure 2 and Figure 4 As shown, a cleaning component 2 is provided below the gap between the two sets of frames 11 and the two sets of roller sections 15. There are multiple sets of cleaning components 2 arranged in an orderly manner, and the multiple sets of cleaning components 2 can thoroughly clean the multiple sections of roller section 15. In this application, only one set is shown in the drawings, and the frame 11 has stepped portions extending outward from the opposite sides. The cleaning assembly 2 includes a cleaning part disposed on the stepped portion. The cleaning part includes guide rods 22 fixed to the two sets of stepped portions and passing through them. The guide rods 22 are trapezoidal, and one end of the two sets of guide rods 22 is connected to a support plate 21. At the same time, a fixing seat 27 slides between the two sets of guide rods 22. A cleaning brush 28 parallel to the roller shaft portion 15 is fixed between the two sets of fixing seats 27 by fasteners. The cleaning brush 28 can contact and clean the two sets of roller shaft portions 15 at the same time. The cleaning brush 28 has a brush shaft, which passes through the fixing seats 27 at both ends and is locked and fixed by fasteners to ensure that the cleaning brush 28 will not easily loosen during use. At the same time, a through groove 111 is provided on the stepped portion for the fixing seat 27 to pass through, which facilitates the installation and movement of the fixing seat 27.

[0029] It should be noted that the brush shaft is movably installed through the frame 11, and an open groove 112 is provided on the frame 11 to provide vertical movement space for the brush shaft. The brush shaft can move up and down along the open groove 112. At the same time, a shaking part is provided at the bottom of the fixed base 27. The shaking part includes a support shaft 23 fixed to the bottom of the fixed base 27. The support shaft 23 is movably installed through the support plate 21, and a spring 24 is sleeved on the support shaft 23. One end of the spring 24 is connected to the bottom surface of the fixed base 27, and the other end is connected to the support plate 21. The spring 24 is used to support the cleaning brush 28. A rotating wheel 25 is fixed to one end of the support shaft 23 that movably passes through the support plate 21. The worker can hold the rotating wheel 25 and apply a downward force to the cleaning brush 28 to squeeze the spring 24. After releasing, the spring force of the spring 24 shakes the impurities attached to the cleaning brush 28, shakes off the impurities, and maintains the cleaning effect of the cleaning brush 28.

[0030] Meanwhile, a concave protective cover 26 is fixed on the side of the two sets of frames 11 that are far apart from each other. The protective cover 26 is used to protect the fixed base 27.

[0031] To further avoid the problem of the cleaning brush 28 contacting the two sets of roller shafts 15 due to the support of spring 24, and then contacting the roller shafts 15 again when shaking off impurities, refer to... Figure 4 As shown, a limiting component 3 is provided on the side of the two sets of frames 11 that are close to each other. The limiting component 3 includes two sets of mounting seats 31 symmetrically arranged along the center line of the waist groove 112. Each mounting seat 31 has a protrusion 32, which is a hollow columnar structure. The two sets of protrusions 32 have an opening at the end that is close to each other, and a convex ball 33 is provided at the opening. The convex ball 33 is connected to the inner wall of the protrusion 32 by a spring 2 (not shown in the figure). There is a gap between the two sets of convex balls 33. It should be noted that the elastic force of the spring 2 is much greater than that of the spring 1 24.

[0032] When a downward force is applied to the cleaning brush 28 by holding the rotating wheel 25, the brush shaft of the cleaning brush 28 squeezes the two sets of convex balls 33 and passes between them. At this time, the tension on the rotating wheel 25 is loosened, and the cleaning brush 28 contacts the bottom surface of the two sets of convex balls 33 through the brush shaft, and there is a gap between the cleaning brush 28 and the roller shaft 15. At this time, when the rotating wheel 25 is held again and a downward force is applied to the cleaning brush 28, the spring 24 is squeezed. After being released, the spring force of the spring 24 shakes the impurities attached to the cleaning brush 28 and shakes them off. At this time, since the spring force of the second spring is much greater than that of the spring 24, the brush shaft of the cleaning brush 28 will not pass the two sets of convex balls 33 unless manually pushed, so as to ensure that the cleaning brush 28 is in a position with a gap with the roller shaft 15 when shaking off impurities, and avoids the impurities from contacting the roller shaft 15 again.

[0033] Working principle: During operation, the drive motor 13 starts, and the power is transmitted to the input shaft of the gearbox 14 via the coupling. The input shaft drives the output shaft to rotate through the bevel gear set, and the output shaft in turn drives a set of roller shafts 15 fixed to it to rotate. At the same time, the sprockets 16 at both ends of the remaining roller shafts 15 rotate with the roller shafts 15. The sprockets 16 mesh with the sprockets 17 and the chain 18, and the support sprockets 110 support and guide the chain 18, so that multiple sets of roller shafts 15 rotate synchronously. The plate is placed on the roller shafts 15 and continuously conveyed as the roller shafts 15 rotate.

[0034] During the conveying of the sheet metal in the roller section 15, the cleaning brush 28 of the cleaning assembly 2 contacts the roller section 15 and cleans the surface of the roller section 15. When it is necessary to clean the impurities attached to the cleaning brush 28, the worker holds the rotating wheel 25 and applies a downward force to the cleaning brush 28. The brush shaft of the cleaning brush 28 squeezes the two sets of convex balls 33 and passes between the two sets of convex balls 33. At this time, the tension on the rotating wheel 25 is released, and the brush shaft of the cleaning brush 28 contacts the bottom surface of the two sets of convex balls 33, so that a gap is formed between the cleaning brush 28 and the roller section 15. Then, the rotating wheel 25 is held again, and a downward force is applied to the cleaning brush 28 to squeeze the spring 24. After that, the rotating wheel 25 is released, and the elastic force of the spring 24 causes the cleaning brush 28 to shake, shaking off the attached impurities. Because the elastic force of spring 22 is much greater than that of spring 24, the brush shaft of cleaning brush 28 will not pass over the two sets of convex balls 33, ensuring that cleaning brush 28 maintains a gap with roller shaft 15 when shaking off impurities, thus preventing impurities from contacting roller shaft 15 again. After cleaning, if it is necessary for cleaning brush 28 to contact roller shaft 15 again for cleaning, simply push the brush shaft of cleaning brush 28 to pass over the two sets of convex balls 33.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
