Description

Technical Field

[0001] This invention relates to the field of building material processing equipment technology, specifically to a keel conveying device. Background Technology

[0002] As a building material, the production process of light steel keel typically includes roll forming, length cutting, and finished product packaging. Currently, conventional forming machines are mostly equipped with horizontal or slightly inclined short-distance conveyor belts at the discharge end. The principle is to use the friction of the belt to horizontally feed the formed keel from below or to the side of the rolls, and then mechanically package it. At present, the conveyor devices and automatic packaging machines on the market are designed for standard profiles within 6 meters. For keels longer than 6 meters, manual handling and packaging are still necessary.

[0003] In actual production, when manually handling keels longer than 6 meters, it is necessary to rely on multiple workers (usually 8 people) to lift, pick up and carry them to the packaging area on the discharge side. This is labor-intensive and the keel surface is easily scratched or deformed due to human error.

[0004] To solve the problem of conveying long keels, some manufacturers have tried to lengthen the single straight conveyor belt or add multiple sets of driven roller conveyors to enable the long keels to be conveyed. However, for keels longer than 6 meters, such solutions are either limited by the limited floor space in the workshop and cannot be installed, or the single horizontal conveyor belt cannot avoid interference from the forming machine below. Summary of the Invention

[0005] This invention provides a keel conveying device to solve the problems of interference and space limitations in molding machines.

[0006] To solve the above-mentioned technical problems, the present invention specifically provides the following technical solution:

[0007] A keel conveying device, characterized in that it includes a conveying mechanism and a receiving platform, wherein the keel is conveyed to the receiving platform through the conveying mechanism;

[0008] The conveying mechanism consists of two conveyor belts, namely a first conveyor belt and a second conveyor belt. One end of the first conveyor belt is close to the discharge port of the forming machine and is set below the discharge port. The other end of the first conveyor belt overlaps with one end of the second conveyor belt in the vertical direction, and a material drop gap of 5cm to 20cm is formed at the overlap. The other end of the second conveyor belt overlaps with the receiving platform and is set above the receiving surface of the receiving platform. The first conveyor belt extends upward along the horizontal plane, and the second conveyor belt extends downward along the horizontal plane.

[0009] A buffer section is provided at the connection between the first conveyor belt and the second conveyor belt. The buffer section is an arc-shaped plate with its arc-shaped concave surface facing upward. One end of the buffer section extends to below the end of the first conveyor belt, and the other end extends to below the beginning of the second conveyor belt. The upper surface of the buffer section is tangent to the conveying direction of the conveyor belt.

[0010] Furthermore, the angle between the first conveyor belt and the horizontal plane is 40° to 60°, and the length of the first conveyor belt is 1m to 2m.

[0011] Furthermore, the angle between the second conveyor belt and the horizontal plane is 30° to 50°, and the length of the second conveyor belt is 2m to 4m.

[0012] Furthermore, the first conveyor belt and the second conveyor belt are mounted on a base plate, and two parallel and horizontally extending slide rails are provided on the base plate in a direction perpendicular to the conveying direction of the conveyor belts. The cross-section of the slide rails is a T-shaped groove or a dovetail groove.

[0013] Baffles are provided on both sides of the first and second conveyor belts. The baffles are perpendicular to the base plate and their height is higher than the upper surface of the conveyor belts. A protrusion matching the cross-section of the slide rail is provided at the bottom of the baffle. The cross-section of the protrusion is a T-shaped protrusion or a dovetail-shaped protrusion. The protrusion is embedded in the slide rail and can slide back and forth along the extension direction of the slide rail, so that the baffle can slide perpendicular to the conveying direction to block the two sides of the conveyor belt and prevent the keel from falling off from the two sides.

[0014] Furthermore, a plurality of springs are provided on the side of the baffle away from the conveyor belt. The springs are evenly distributed along the extension direction of the baffle. The axial direction of each spring is perpendicular to the surface of the baffle. One end of the spring is fixedly connected to the baffle, and the other end is fixedly connected to a support. The support is parallel to the baffle and fixed to the base plate.

[0015] When the baffle is subjected to lateral pressure from the keel, it can slide outward along the slide rail through the protrusion, compress the spring, and return to its original position under the elastic restoring force of the spring, so as to guide and buffer the keel.

[0016] Furthermore, anti-slip ridges are provided on the outer surfaces of the first conveyor belt and the second conveyor belt. The anti-slip ridges are evenly distributed along the conveying direction of the conveyor belt and are parallel to the rollers of the conveyor belt. The distance between two adjacent anti-slip ridges is 3cm to 10cm, and the height of the anti-slip ridges is 2mm to 8mm.

[0017] Furthermore, anti-slip textures are provided on the outer surfaces of the first conveyor belt and the second conveyor belt. The anti-slip textures are multiple diamond-shaped grooves or ridges distributed between two adjacent anti-slip ridges.

[0018] Furthermore, the anti-slip texture is evenly distributed in an array between two adjacent anti-slip ridges.

[0019] Furthermore, the buffer section is fixed to the base plate by a bracket, and gaps are maintained between the buffer section and the end of the first conveyor belt and between the buffer section and the beginning of the second conveyor belt.

[0020] Furthermore, the end of the first conveyor belt is located directly above the starting end of the second conveyor belt, and the horizontal overlap length between the two is 10cm to 30cm, while the vertical height of the material drop gap is 5cm to 20cm.

[0021] Compared with the prior art, the present invention has the following advantages:

[0022] By adopting a segmented bending conveyor structure in which the first conveyor belt extends upward along the horizontal plane and the second conveyor belt extends downward along the horizontal plane, a spatial transition path with a high front and low back is formed, allowing the keel to avoid interference from the forming machine below and conveying the long keel out. At the same time, relying on the segmented conveyor structure with two different inclination angles, the impact of workshop space on the layout of the conveyor device is reduced.

[0023] The arc-shaped buffer section at the connection between the first and second conveyor belts extends with its concave-facing arc-shaped plate to the bottom of the ends and starting ends of the two conveyor belts, respectively. Its upper surface is tangent to the conveying direction, so that the keel is smoothly supported and guided when crossing the gap, thus avoiding bending or impact damage caused by excessive suspended span.

[0036] 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, and 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.

[0037] In existing light steel keel production lines, the forming machine 1 and its subsequent conveying equipment are usually limited by the packaging device, and can only automatically convey keels with a length of less than 6 meters. When it is necessary to produce keels longer than 6 meters, the equipment cannot complete the automatic conveying, and manual material receiving and conveying must be used. A single production line requires at least 8 people to operate.

[0038] This method is not only labor-intensive and costly, but also prone to scratching the keel surface during manual material handling, affecting the product's appearance quality. In addition, the discharge port of molding machine 1 has a certain height. If a single horizontal conveyor belt is used, it is easy to cause spatial interference with the lower structure of molding machine 1, and it is difficult to achieve stable long-distance transportation due to the limited length of the workshop space.

[0039] To address the aforementioned problems, this invention provides a keel conveying device, which is installed on the molding machine 1 and is a modification and upgrade based on the specific structure of the molding machine 1. The molding machine 1 itself can be considered prior art, and its components such as rollers and frame near the discharge port will not be described in detail here.

[0040] The following describes in detail a keel conveying device of the present invention, with reference to its specific structure. Figures 1 to 7 As shown, the keel conveying device includes a conveying mechanism 2 and a receiving platform 3. The keel 4 is conveyed to the receiving platform 3 through the conveying mechanism 2. The cooperation of each structure realizes the stable conveying operation of the keel.

[0041] like Figure 1 The conveyor mechanism 2 consists of two conveyor belts, namely the first conveyor belt 21 and the second conveyor belt 22.

[0042] Both the first conveyor belt 21 and the second conveyor belt 22 include a conveyor belt, a drive roller, a driven roller, and a drive motor for rotating the drive roller, which are existing technologies and will not be described in detail here. The drive motor can be fixed below or to the side of the base plate 201 and connected to the drive roller via chain drive or belt drive. The switch controlling the start and stop of the drive motor can be interlocked with the controller of the molding machine 1 to achieve synchronous conveying.

[0043] Furthermore, one end of the first conveyor belt 21 is close to the discharge port of the molding machine, and this end is set lower than the discharge port. The other end of the first conveyor belt 21 overlaps with one end of the second conveyor belt 22 in the vertical direction, and a material drop gap of 5cm to 20cm is formed at the overlap. The other end of the second conveyor belt 22 overlaps with the receiving platform 3, and this end is set higher than the receiving surface of the receiving platform 3. The first conveyor belt 21 extends upward along the horizontal plane, and the second conveyor belt 22 extends downward along the horizontal plane.

[0044] The discharge port of the molding machine 1 is relatively narrow. The material is first lifted upward by the first conveyor belt 21 and then tilted downward by the second conveyor belt 22, which allows the keel 4 to avoid the interference area at the bottom of the molding machine 1. At the same time, relying on the segmented conveyor structure with two different inclination angles, the entire support and conveying distance of the keel is extended, which is not limited by the space of the workshop.

[0045] Specifically, the angle between the first conveyor belt 21 and the horizontal plane is 40° to 60°, and the length of the first conveyor belt 21 is 1m to 2m. The angle between the second conveyor belt 22 and the horizontal plane is 30° to 50°, and the length of the second conveyor belt 22 is 2m to 4m.

[0046] The above-mentioned angle and length range can be adjusted according to the actual workshop height and the discharge port position of molding machine 1.

[0047] The large angle and short length of the first conveyor belt 21 can quickly lift the keel from the molding machine and remove it from the molding machine's discharge area. The small angle and long length of the second conveyor belt 22 can smoothly transition the keel's conveying height, achieving stable transport of the keel to the receiving platform 3.

[0048] In this embodiment, the first conveyor belt 21 and the second conveyor belt 22 are mounted on the base plate 201. Two parallel and horizontally extending slide rails 206 are provided on the base plate 201 in a direction perpendicular to the conveying direction of the conveyor belts. The cross-section of the slide rails 206 is a T-shaped groove or a dovetail groove.

[0049] To prevent the keel from falling to either side of the conveyor belt during transport, such as Figures 5 to 7 As shown, baffles 203 are provided on both sides of the first conveyor belt 21 and the second conveyor belt 22. The baffles 203 are perpendicular to the bottom plate 201 and their height is higher than the upper surface of the conveyor belt. A protrusion 207 matching the cross-section of the slide rail 206 is provided at the bottom of the baffle 203. The cross-section of the protrusion 207 is a T-shaped protrusion or a dovetail-shaped protrusion. The protrusion 207 is embedded in the slide rail 206 and can slide back and forth along the extension direction of the slide rail, so that the baffle 203 can slide perpendicular to the conveying direction to block the two sides of the conveyor belt and prevent the keel from falling off from the two sides.

[0050] Furthermore, multiple springs 205 are provided on the side of the baffle 203 away from the conveyor belt. The springs 205 are evenly distributed along the extension direction of the baffle 203. The axial direction of each spring 205 is perpendicular to the surface of the baffle 203. One end of the spring 205 is fixedly connected to the baffle 203, and the other end is fixedly connected to a support 204. The support 204 is parallel to the baffle 203 and fixed to the base plate 201.

[0051] When the baffle 203 is subjected to lateral pressure from the keel 4, it can slide outward along the slide rail 206 through the protrusion 207, while compressing the spring 205, and then return to its original position under the elastic restoring force of the spring 205, so as to guide and buffer the keel 4.

[0052] Specifically, when the keel 4 shifts laterally during transport, its side first contacts and pushes the baffle 203. Under this force, the baffle 203 slides along the slide rail 206 away from the conveyor belt via the protrusion 207, simultaneously compressing the spring 205. The reaction force generated by the compressed spring 205 is applied to the side of the keel 4 through the baffle 203, pushing the keel 4 back towards the center of the conveyor belt, thus achieving automatic correction of the keel 4. Once the correction is complete, the spring 205 pushes the baffle 203 back to its original position.

[0053] Meanwhile, an elastic material can be installed on the side of the baffle 203 closest to the conveyor belt to prevent scratches on the keel surface. The elastic material is preferably a rubber strip, silicone strip, or brush strip, which is fixed to the inner side of the baffle 203 by adhesive or slots.

[0054] Because the first conveyor belt 21 is inclined upwards and the second conveyor belt 22 is inclined downwards, the keel 4 may slip due to gravity on the inclined section.

[0055] Therefore, such as Figure 4 Anti-slip ridges 208 are provided on the outer surfaces of the first conveyor belt 21 and the second conveyor belt 22. The anti-slip ridges 208 are evenly distributed along the conveying direction of the conveyor belt and parallel to the rollers of the conveyor belt. The distance between two adjacent anti-slip ridges 208 is 3cm to 10cm, and the height of the anti-slip ridges 208 is 2mm to 8mm. The directional arrangement of the anti-slip ridges 208 increases the contact friction between the conveyor belt and the bottom of the keel, and restricts the keel from slipping on the inclined conveyor belt.

[0056] Anti-slip patterns 209 are also provided on the outer surfaces of the first conveyor belt 21 and the second conveyor belt 22. The anti-slip patterns 209 are multiple diamond-shaped grooves or ridges distributed between two adjacent anti-slip ridges 208. The anti-slip patterns 209 are evenly distributed in an array between two adjacent anti-slip ridges 208. The array-distributed anti-slip patterns 209 can fill the blank areas between the anti-slip ridges 208, improve the anti-slip performance of the conveyor belt surface, and form a double-layer anti-slip structure with the anti-slip ridges 208, further reducing the slippage and displacement of the conveyor belt.

[0057] A buffer section 2010 is provided at the connection between the first conveyor belt 21 and the second conveyor belt 22. The buffer section 2010 is an arc-shaped plate with its arc-shaped concave surface facing upward. One end of the buffer section 2010 extends to below the end of the first conveyor belt 21, and the other end extends to below the beginning of the second conveyor belt 22. The upper surface of the buffer section 2010 is tangent to the conveying direction of the conveyor belt.

[0058] Specifically, the buffer section 2010 is fixed to the base plate 201 by a bracket, and gaps are maintained between the buffer section 2010 and the end of the first conveyor belt 21, as well as between the buffer section 2010 and the beginning of the second conveyor belt 22. The arc-shaped plate structure of the buffer section 2010 conforms to the conveying trajectory of the two conveyor belts. The tangential structure design can eliminate conveying inflection points, and the gap setting can avoid frictional interference between the conveyor belt and the buffer section 2010 during operation, ensuring the normal operation of the conveyor belt.

[0059] The end of the first conveyor belt 21 is located directly above the beginning of the second conveyor belt 22, and the horizontal overlap between the two is 10cm to 30cm, while the vertical height of the material drop gap is 5cm to 20cm. The overlapping structure of the two conveyor belts, combined with the supporting structure of the buffer section 2010, supports and guides the keel at the gap, avoiding deformation and impact problems caused by the suspended span of the keel.

[0060] When the front end of the keel 4 leaves the first conveyor belt 21, it first contacts the arc surface of the buffer section 2010, and under the guidance of the arc surface, it smoothly changes its direction of movement and then enters the second conveyor belt 22, reducing the impact force caused by the sudden change in angle.

[0061] Compared to existing manual material handling methods, this device reduces the number of operators required for a single production line from 8 to 1, and avoids scratches on the keel surface during manual material handling. Through segmented inclined conveying, adaptive correction baffles, anti-slip surfaces, and curved buffer transitions, the device achieves smooth and automatic transport of long keels from the forming machine to the receiving platform, overcoming spatial interference problems while ensuring conveying quality.

[0062] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
