A digital strip feeding mechanism

Abstract

This utility model discloses a digital strip feeding mechanism, belonging to the field of strip feeding technology. It includes a storage hopper, a movable frame mounted on the top of the hopper, a partition inside the hopper, a guide plate mounted on one side of the hopper, and electrical cabinets at both ends of the hopper. In this utility model, by setting up a conveying assembly, during the feeding process, the powder first falls onto the belt surface on the outer wall of the drive shaft and driven shaft, and moves with the belt. When it reaches above the driven shaft, it falls as the belt continues to move. Because the diameters of the drive shaft and driven shaft are different, the belt has a certain tilt angle, allowing the powder to gradually move downwards. Simultaneously, because the diameter of the driven shaft is smaller, its height above the brick surface is lower, resulting in less impact force when the powder falls onto the brick surface, thus preventing the powder from scattering and ensuring the integrity of the pattern.

Description

Technical Field

[0001] This utility model belongs to the field of strip feeding technology, and in particular relates to a digital strip feeding mechanism. Background Technology

[0002] A strip feeding machine is a feeding mechanism that controls the gate to feed material according to the width of the brick surface. It feeds strips of powder to the next process to generate patterns. At the same time, it can control the opening and closing of different gates so that the powder can fall into different positions to form different patterns.

[0003] During the material feeding process, the traditional material feeding method uses roller feeding. Due to issues with the material drop height, powder falls and spreads, and the positioning is inaccurate. Furthermore, the control gate is located too far back in the center of the roller, making it difficult for the powder to slide off when the gate is opened. If the center is too far forward, material leakage is likely, which affects the effect of the formed pattern and results in an unclear or even damaged pattern. Utility Model Content

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0026] 1. In this utility model, a conveying assembly is installed inside. During use, powder is placed into the storage hopper. The width of the pattern formed by the material is changed by adjusting the position of the partition. The first and second gates are controlled to discharge the powder. After the powder is discharged from the storage hopper, the drive motor is started to rotate the drive shaft. The rotation of the drive shaft drives the belt to rotate. At this time, the powder falls on the surface of the belt and moves with the belt. It then moves to the top of the driven shaft and slides off the surface of the belt as the belt continues to move, eventually landing on the brick surface. Because the diameter of the driven shaft is small, the belt can form a certain slope, thereby reducing the impact of the powder sliding off the belt surface. Furthermore, because the driven shaft and the brick... The surfaces are relatively close together, so that when the powder slides off the belt surface and comes into contact with the brick surface, it does not generate a large impact, thus avoiding the powder from scattering after falling and ensuring the stable formation of the pattern. Through this design, during the feeding process, the powder first falls on the belt surface on the outer wall of the drive shaft and driven shaft, and moves with the belt. When it reaches above the driven shaft, it falls as the belt continues to move. Because the diameters of the drive shaft and driven shaft are different, the belt has a certain tilt angle, which allows the powder to gradually move downward. At the same time, because the diameter of the driven shaft is smaller, its height above the brick surface is lower, which reduces the impact force of the powder falling on the brick surface, thus preventing the powder from scattering and ensuring the integrity of the pattern.

[0027] 2. In this utility model, by incorporating a gate assembly, during the material feeding process, the lifting and lowering of the second gate and the first gate can be controlled by the first and second cylinders. This allows powder to pass underneath the first and second gates at different positions, forming different patterns. During the lifting and lowering of the first and second gates, since they are located between the top plate and the guide plate, the top plate and guide plate can limit their movement, reducing powder leakage due to misalignment. Furthermore, since the second gate has limiting blocks on both sides that slide with the grooves on both sides of the first gate, the first and second gates are further connected, further preventing misalignment. During use, the first spring pushes the baffle to contact the belt surface. This design avoids gaps between the first and second gates and the belt caused by prolonged friction between the belt and the first and second gates during operation. By controlling the discharged powder through the gates, the guide plate and top plate limit the movement of the first and second gates, reducing the risk of gaps and powder leakage due to misalignment. Furthermore, the connection between the limiting blocks on both sides of the second gate and the first gate further strengthens the connection, preventing powder leakage from the gap. During the feeding process, the first spring ensures constant contact between the baffle and the belt, preventing gaps caused by prolonged friction between the gates and the belt.

[0028] 3. In this utility model, by incorporating a cleaning component, during the conveyor belt transport of powder, a cleaning plate can clean the surface of the belt as it rotates back up from below. This cleaning plate removes residual powder from the belt surface, preventing it from affecting the transport of powder again and ensuring the quality of the pattern formed by the powder. After cleaning the belt surface with the cleaning plate, a cleaning roller adheres any remaining powder to the belt surface, further preventing powder residue. A second spring pushes a slider to ensure the cleaning roller remains in contact with the belt surface. This design achieves continuous cleaning of the belt surface during powder transport via the cleaning plate and cleaning roller, ensuring the belt surface remains clean after each rotation and preventing powder residue from affecting transport and thus ensuring the quality of the pattern formed by the powder.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0041] Please see Figures 1-9 This utility model provides a technical solution: a digital strip-shaped feeding mechanism, including a storage hopper 2, a movable frame 1 installed at the top of the storage hopper 2, a partition 3 inside the storage hopper 2, a guide plate 8 installed on one side of the storage hopper 2, and electrical cabinets 4 at both ends of the storage hopper 2; a gate assembly 6 installed on one side of the storage hopper 2, with the bottom end of the gate assembly 6 located on the side of the discharge port of the storage hopper 2; a conveying assembly 5 installed below the discharge port of the storage hopper 2, with the bottom end of the gate assembly 6 in contact with the surface of the conveying assembly 5; and a cleaning assembly 7 installed on the other side of the discharge port of the storage hopper 2, with the bottom end of the cleaning assembly 7 in contact with the surface of the conveying assembly 5.

[0042] The conveying assembly 5 includes a support plate 56, a bearing 57 mounted on one side of the support plate 56, a bearing base plate 58 mounted on the other side of the support plate 56, a first fixing plate 59 mounted on the top of the bearing base plate 58, a drive shaft 52 mounted on the inner ring of the bearing 57, a drive motor 51 mounted on one end of the drive shaft 52, a belt 55 provided on the outer wall of the drive shaft 52, a side plate 53 mounted on one end of the bearing base plate 58, a driven shaft 54 ​​rotatably mounted on the side plate 53 through a through hole, the outer wall of the driven shaft 54 ​​contacting the inner side of the belt 55, one side of the drive motor 51 fixed to the support plate 56, and one side of the first fixing plate 59 fixedly connected to one side of the storage hopper 2.

[0043] The specific implementation is as follows: When in use, the powder is placed into the storage hopper 2. The width of the pattern formed by the material is changed by adjusting the position of the partition 3. The first gate 67 and the second gate 69 are controlled to discharge the powder. After the powder is discharged from the storage hopper 2, the drive motor 51 is started to drive the drive shaft 52 to rotate. The rotation of the drive shaft 52 drives the belt 55 to rotate. At this time, the powder falls on the surface of the belt 55 and moves with the belt 55. It then moves to the top of the driven shaft 54 ​​and slides off the surface of the belt 55 as the belt 55 continues to move, and then falls onto the brick surface. At the same time, because the diameter of the driven shaft 54 ​​is small, the belt 55 can form a certain slope, thereby reducing the impact of the powder sliding off the surface of the belt 55. Also, because the driven shaft 54 ​​is relatively close to the brick surface, the powder does not produce a large impact when it comes into contact with the brick surface after sliding off the surface of the belt 55, thereby avoiding the powder from scattering after falling and ensuring that the pattern can be formed stably.

[0044] The gate assembly 6 includes a third fixing plate 62, with second fixing plates 61 mounted at both ends of the third fixing plate 62. An adjusting block 64 is mounted on one side of the third fixing plate 62, and a top plate 63 is mounted on one end of the adjusting block 64. A first cylinder 65 is mounted on one side of the third fixing plate 62, and a second cylinder 66 is mounted on the same side, with the first cylinder 65 located below the second cylinder 66. A second gate 69 is mounted on the telescopic end of the first cylinder 65, and limit blocks 68 are mounted on both sides of the second gate 69. A first gate 67 is mounted on the telescopic end of the second cylinder 66, with grooves on both sides of the first gate 67, and the limit blocks 68 are slidably connected to the grooves. Gate 67 and second gate 69 are arranged in a cross pattern, with the bottom ends of the first gate 67 and second gate 69 at the same height. A sliding groove 612 is provided on one side of the bottom end of the first gate 67 and the second gate 69. A baffle 611 is slidably installed in the sliding groove 612. A first spring 610 is installed on one side of the baffle 611. The other end of the first spring 610 is fixedly connected to the gate and is in a compressed state. One side of the second fixing plate 61 is fixedly connected to the storage hopper 2. The first gate 67 and second gate 69 are located on one side of the guide plate 8 and are in contact with the guide plate 8. The other side of the first gate 67 and second gate 69 is in contact with the top plate 63.

[0045] The specific implementation is as follows: During the feeding process, the lifting and lowering of the second gate 69 and the first gate 67 can be controlled by the first cylinder 65 and the second cylinder 66. The powder passes through the first gate 67 and the second gate 69 at different positions to form different patterns. During the lifting and lowering of the first gate 67 and the second gate 69, since the first gate 67 and the second gate 69 are located between the top plate 63 and the guide plate 8, the top plate 63 and the guide plate 8 can limit the movement of the first gate 67 and the second gate 69, reducing powder leakage due to misalignment between the first gate 67 and the second gate 69. Meanwhile, since the second gate plate 69 is provided with limiting blocks 68 on both sides, and the limiting blocks 68 slide with the grooves on both sides of the first gate plate 67, the first gate plate 67 and the second gate plate 69 are further connected, thereby further preventing the first gate plate 67 and the second gate plate 69 from shifting. At the same time, during the use of the first gate plate 67 and the second gate plate 69, the first spring 610 can push the baffle 611 to contact the surface of the belt 55, thereby preventing the belt 55 from rubbing against the first gate plate 67 and the second gate plate 69 for a long time during operation, which would cause gaps to form between the first gate plate 67, the second gate plate 69 and the belt 55.

[0046] The cleaning assembly 7 includes a cover plate 76, a support block 74 is installed on one side of the cover plate 76, a slider 75 is slidably installed on the support block 74 through a groove opened inside, a second spring 73 is installed on the top of the slider 75, the top of the second spring 73 is fixedly connected to the support block 74, the slider 75 is rotatably installed with an installation shaft 77 through a through hole opened inside, a cleaning roller 72 is installed on the outer wall of the installation shaft 77, a cleaning plate 71 is installed on one side of the support block 74, one side of the cover plate 76 is fixedly connected to the bottom of the storage hopper 2, the bottom of the cleaning plate 71 is in contact with the surface of the belt 55, and the cleaning roller 72 is in contact with the surface of the belt 55 under the action of the second spring 73.

[0047] The specific implementation is as follows: During the process of conveying powder by belt 55, the surface of belt 55 that has restarted from below can be cleaned by cleaning plate 71, thereby cleaning off the residual powder on the surface of belt 55, preventing the belt 55 from affecting the transport of powder again, and thus ensuring the quality of the pattern formed by the powder. After cleaning the surface of belt 55 by cleaning plate 71, the remaining powder on the surface of belt 55 can be adhered by cleaning roller 72, thereby further preventing powder residue on the surface of belt 55. The second spring 73 pushes slider 75 to ensure that cleaning roller 72 always keeps in contact with the surface of belt 55.

[0048] Working principle: During use, powder is placed into the storage hopper 2. The width of the pattern formed by the material is changed by adjusting the position of the partition 3. The raising and lowering of the second gate 69 and the first gate 67 are controlled by the first cylinder 65 and the second cylinder 66. The powder passes through the first gate 67 and the second gate 69 at different positions to form different patterns. During the raising and lowering process of the first gate 67 and the second gate 69, since the first gate 67 and the second gate 69 are located between the top plate 63 and the guide plate 8, the top plate 63 and the guide plate 8 can move the first gate 67 and the second gate 69. The limiting mechanism reduces powder leakage caused by misalignment between the first gate plate 67 and the second gate plate 69. Furthermore, the limiting blocks 68 on both sides of the second gate plate 69 slide against the grooves on both sides of the first gate plate 67, further connecting the first gate plate 67 and the second gate plate 69 and preventing misalignment. During use, the first spring 610 pushes the baffle 611 to contact the surface of the belt 55, preventing prolonged friction between the belt 55 and the first and second gate plates 67 and 69 during operation. This results in gaps between the first gate plate 67 and the second gate plate 69 and the belt 55. After the powder is discharged from the storage hopper 2, the drive motor 51 is started to drive the drive shaft 52 to rotate, thereby driving the belt 55 to rotate. At this time, the powder falls on the surface of the belt 55 and moves with the belt 55, moving to the top of the driven shaft 54. As the belt 55 continues to move, it slides off the surface of the belt 55 and falls onto the brick surface. At the same time, because the diameter of the driven shaft 54 ​​is small, the belt 55 can form a certain slope, thereby reducing the impact of the powder sliding off the surface of the belt 55. During the process of conveying powder, the surface of the belt 55 that is restarting from below can be cleaned by the cleaning plate 71, thereby removing the powder residue on the surface of the belt 55 and preventing it from affecting the powder when the belt 55 is transported again, thus ensuring the quality of the pattern formed by the powder. After the surface of the belt 55 is cleaned by the cleaning plate 71, the remaining powder on the surface of the belt 55 can be adhered by the cleaning roller 72, thereby further preventing powder residue on the surface of the belt 55. The second spring 73 pushes the slider 75 to ensure that the cleaning roller 72 always keeps in contact with the surface of the belt 55.

[0049] 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.
