Description

Technical Field

[0001] This invention relates to the field of waste metal recycling technology, specifically to a waste corrugated steel tile recycling, crushing, and feeding device. Background Technology

[0002] Color steel roofing sheets are widely used in the construction industry as lightweight building materials, but their service life is only about 10 years. They are prone to safety hazards and environmental pollution due to corrosion, damage, or volatilization of toxic substances (such as polystyrene resin) in the interlayer. A large amount of waste color steel roofing sheets are generated in my country every year. Traditional recycling mainly relies on physical crushing and sorting. The width of traditional color steel roofing sheets is usually larger than the width of the feed inlet of small crushing equipment. Therefore, it is necessary to rely on manual bending or cutting operations before entering the crushing equipment for crushing. Manual operation is inefficient and costly. If large crushing equipment is used, it will increase the production cost. Therefore, we propose a waste color steel roofing sheet recycling, crushing and feeding equipment. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a waste corrugated steel tile recycling, crushing, and feeding device. It overcomes the deficiencies of existing technologies, has a reasonable design and compact structure, and solves the problems of high efficiency and low cost associated with the manual bending or cutting operations required for crushing waste corrugated steel tiles.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a waste corrugated steel tile recycling, crushing, and feeding device, comprising a crusher, a roller conveyor on the feed inlet side of the crusher, an mounting frame on the roller conveyor, a pressure plate at the bottom of the middle part of the mounting frame, a gap for the corrugated steel tile to pass through between the bottom of the pressure plate and the top of the conveying roller of the roller conveyor, and several pressure arm assemblies symmetrically arranged inside the roller conveyor, the pressure arm assemblies being located in the gap between two conveying rollers, one end of which is rotatably positioned below the conveying roller, and the other end being able to deflect upwards, so that the two sides of the corrugated steel tile on the roller conveyor bend towards the top of the pressure plate, thereby reducing the relative width of the corrugated steel tile.

[0005] Preferably, the pressure arm assembly is provided with a bending unit, the bending unit includes a sleeve, a pressure rod is slidably connected inside the sleeve, and a bending head is provided on one side of the pressure rod extending out of the sleeve, so as to squeeze the top of the color steel tile above the edge of the pressure plate when the pressure arm assembly deflects upward to bend the color steel tile.

[0006] Preferably, the pressure arm assembly includes a deflection arm and a pressure head component. The sleeve is disposed on the upper side of the deflection arm, and an insert plate is provided on one side of the pressure head component. A slot for inserting the insert plate is provided inside the end of the deflection arm, and a connecting spring connected to the insert plate is provided in the slot.

[0007] Preferably, the inner cavity of the sleeve is connected to the inner cavity of the slot, and one end of the pressure rod is connected to a triangular block that is inserted into the slot. A support spring is connected between the triangular block and the inner cavity of the sleeve. A push groove for the triangular block is provided on one side of the insert plate so as to push the triangular block toward the outside of the slot when the insert plate moves.

[0008] Preferably, the pressure head component includes a base connected to the end of the insert plate, and a pressure roller is rotatably connected inside the base.

[0009] Preferably, the roller conveyor is provided with a drive unit, the drive unit includes a drive gear connected to a drive source, a first driven gear is meshed with the outer wall of the drive gear, a second driven gear is meshed with the outer wall of the first driven gear, and both the first driven gear and the second driven gear are provided with a rotating shaft that follows their rotation, and each rotating shaft is provided with a plurality of pressure arm assemblies on its outer wall.

[0010] Preferably, the bottom of the pressure plate is provided with a plurality of rollers arranged at equal intervals along its length.

[0011] Preferably, the pressure plate is located at the middle of the top of the roller conveyor, and its width is greater than half the distance between the two side baffles on the roller conveyor, but less than the width of the feed inlet of the crusher.

[0012] This invention provides a waste corrugated steel tile recycling, crushing, and feeding device. It has the following beneficial effects:

[0013] 1. By setting up a pressure arm assembly and a pressure plate on the roller conveyor, when the color steel tile is conveyed to the bottom of the pressure plate, the pressure arm assembly flips upward synchronously, and works with the pressure plate to bend the two sides of the color steel tile, reducing the relative width. There is no need for manual bending or cutting, which greatly improves the crushing and processing efficiency, reduces the dependence on manual labor, and lowers labor costs.

[0014] 2. There is no need to use large crushing equipment to process the wide color steel tiles; small crushing equipment can be used, saving on equipment purchase and maintenance costs.

[0015] 3. The pressure arm assembly is equipped with a bending unit. The bending head presses the bending part of the color steel tile to prevent it from rebounding and causing the overall height to be too high, which would affect the subsequent crushing. The pressure arm assembly has elasticity when under force, which can buffer and avoid damage. It also makes the pressure head part fit better against the surface of the color steel tile, ensuring uniform and stable extrusion and improving the bending effect. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] See attached document Figure 1-8 A waste corrugated steel tile recycling, crushing, and feeding device includes a crusher 1. A roller conveyor 2 is provided on the feed inlet side of the crusher 1 for conveying corrugated steel tiles. The distance between the baffles on both sides of the roller conveyor 2 is adapted to the width of the corrugated steel tiles to ensure the stability of the conveying.

[0027] The roller conveyor 2 is equipped with a mounting frame 3. The mounting frame 3 is in the shape of an inverted "mountain". The bottom of the middle part of the mounting frame 3 is equipped with a pressure plate 4. A gap is left between the bottom of the pressure plate 4 and the top of the conveyor roller of the roller conveyor 2 for the color steel tile to pass through.

[0028] Several pressure arm assemblies 5 are symmetrically arranged along the conveying centerline inside the roller conveyor 2. The pressure arm assembly 5 is located in the gap between two conveying rollers. One end of the pressure arm assembly 5 is rotatably located below the conveying roller, and the other end can be deflected upwards, so that the two sides of the color steel tile on the roller conveyor 2 bend towards the top of the pressure plate 4 to reduce the relative width of the color steel tile.

[0029] When the corrugated steel sheet is conveyed on the roller conveyor 2 to the bottom of the pressure plate 4, several symmetrically arranged pressure arm assemblies 5 simultaneously flip upwards and cooperate with the pressure plate 4, causing the two sides of the corrugated steel sheet on the roller conveyor 2 to bend towards the top of the pressure plate 4, thereby reducing the relative width of the corrugated steel sheet. This solves the problem that the width of traditional corrugated steel sheets is greater than the feed inlet width of small crushing equipment, requiring manual bending or cutting. It greatly improves processing efficiency, reduces labor costs, and eliminates the need for large crushing equipment, saving costs.

[0030] The pressure arm assembly 5 is equipped with a bending unit, which includes a hollow sleeve 61. A pressure rod 62 is slidably connected inside the sleeve 61. A bending head 63 is provided on one side of the pressure rod 62 extending out of the sleeve 61. The bending head 63 has a trapezoidal structure that is narrow at the top and wide at the bottom. When the pressure arm assembly 5 deflects upward to bend the corrugated steel sheet, the bending head 63 will squeeze the top of the corrugated steel sheet above the edge of the pressure plate 4, causing the bend of the corrugated steel sheet to deform downward. This is to avoid the corrugated steel sheet from rebounding too much when the pressure arm assembly 5 is not squeezing it, which would cause its overall height to be too high and affect its subsequent crushing.

[0031] The pressure arm assembly 5 includes a deflection arm 51 and a pressure head component. A sleeve 61 is disposed on the upper side of the deflection arm 51. An insert plate 53 is provided on one side of the pressure head component. A slot 54 for inserting the insert plate 53 is provided inside the end of the deflection arm 51. Both the insert plate 53 and the slot 54 are arc-shaped structures. A connecting spring 55 connected to the insert plate 53 is provided in the slot 54. When the two sides of the color steel tile are pressed above the pressure plate 4 by the pressure head component of the pressure arm assembly 5, the pressure arm assembly 5 as a whole has a certain degree of elasticity when subjected to force, which can effectively buffer and prevent the pressure arm assembly 5 from being damaged due to excessive force. Moreover, its elasticity allows the pressure head component to better fit the surface of the color steel tile, ensuring the uniformity and stability of the extrusion, and effectively reducing the rebound of the color steel tile.

[0032] The inner cavity of the sleeve 61 is connected to the inner cavity of the slot 54, and one end of the pressure rod 62 is connected to a triangular block 64 that is inserted into the slot 54. A support spring 65 is connected between the triangular block 64 and the inner cavity of the sleeve 61. A push groove 56 that matches the triangular block 64 is opened on one side of the insert plate 53. When the insert plate 53 is subjected to a reaction force and moves into the slot 54, the push groove 56 will push the triangular block 64 and make it move towards the outside of the slot 54. This further causes the pressure rod 62 to drive the bending head 63 to squeeze the bending part of the color steel tile, reduce the rebound of the color steel tile after bending, and facilitate subsequent crushing.

[0033] The pressure head component includes a base 521 connected to the end of the insert plate 53. A pressure roller 522 is rotatably connected inside the base 521. When the pressure head component comes into contact with the color steel tile, the pressure roller 522 will roll on the surface of the color steel tile. On the one hand, it can provide uniform pressure and improve the bending effect. On the other hand, it can also reduce the pressure on the pressure head component and protect the pressure head component.

[0034] The roller conveyor 2 is equipped with a drive unit, which includes a drive gear 71 connected to a drive source. The outer wall of the drive gear 71 is meshed with a first driven gear 72, and the outer wall of the first driven gear 72 is meshed with a second driven gear 73. Both the first driven gear 72 and the second driven gear 73 are equipped with rotating shafts 74 that follow their rotation. The outer wall of each rotating shaft 74 is equipped with several pressure arm assemblies 5. The drive source uses a servo motor or motor to provide power to drive the drive gear 71 to rotate, which further causes the first driven gear 72 and the second driven gear 73 to rotate in opposite directions. That is, at this time, the two rotating shafts 74 rotate in opposite directions, so that the several symmetrically arranged pressure arm assemblies 5 will flip upward synchronously, ensuring that the bending of the color steel tile is efficient and accurate.

[0035] The bottom of the pressure plate 4 is provided with several rollers 41 arranged at equal intervals along its length to reduce the friction between the color steel tile and the pressure plate 4 as a whole, and to prevent the roller conveyor 2 from being unable to transport the bent color steel tile after bending.

[0036] To further reduce the friction between the corrugated steel sheet and the pressure plate 4, several rollers 41 arranged at equal intervals along the length of the pressure plate 4 can also be provided on the top of the pressure plate 4.

[0037] To ensure that the bent corrugated steel sheet can enter the crusher 1, the pressure plate 4 is located in the middle of the top of the roller conveyor 2, and its width is greater than half the distance between the two side baffles on the roller conveyor 2, but less than the width of the feed inlet of the crusher 1.

[0038] Working principle: When the color steel tile is conveyed on the roller conveyor 2 to the pressure plate 4, the drive unit starts to work. The drive source drives the drive gear 71 to rotate. Through the first driven gear 72 and the second driven gear 73, the two rotating shafts 74 rotate in opposite directions, thereby causing the symmetrically arranged pressure arm assemblies 5 to flip upward synchronously.

[0039] The pressure head of the pressure arm assembly 5 contacts the color steel tile, and the pressure roller 522 on it rolls on the surface of the color steel tile, providing uniform pressure and reducing its own stress. When the pressure arm assembly 5 is under overall stress, due to the arc structure of the insert plate 53 and the slot 54 and the connecting spring 55, it has a certain degree of elasticity, which can buffer and avoid damage, and better fit the surface of the color steel tile, ensuring uniform and stable extrusion.

[0040] At the same time, the bending unit plays a role. When the insert plate 53 moves into the slot 54 under the reaction force, the pusher 56 pushes the triangular block 64 to move outward from the slot 54, the support spring 65 is compressed, and the pressure rod 62 drives the bending head 63 to squeeze the bending part of the color steel tile, reducing the rebound and making it easier for the bent color steel tile to enter the crusher 1 for crushing. This solves the problem that traditional color steel tiles need to be manually processed due to width issues, improves processing efficiency, and reduces costs.
