Abstract

The application relates to a reciprocating feeding mechanism, which comprises a frame assembly, a directional conveying belt arranged on the frame assembly and advancing in a conveying direction, the outer edge of the frame assembly being higher than the surface of the directional conveying belt to confine materials on the conveying belt, a change direction conveying belt arranged on the frame assembly and adjacent to and in the same plane as the directional conveying belt and reciprocating in the conveying direction, the width of the directional conveying belt and the change direction conveying belt being 1.2-1.8 times the width of the materials, and a chain plate arranged at the end of the advancing direction of the change direction conveying belt, the abutting plate on the chain plate being in contact with the materials and being obliquely arranged so that the length of the change direction conveying belt in the conveying direction gradually decreases from the side close to the directional conveying belt to the side far away from the directional conveying belt. The above scheme ensures no jamming in the conveying process, more materials can be fed at one time, and operators need not be on the production line to watch at all times, so that the feeding amount is large and efficient, and the working strength of the operators is reduced.

Description

Technical Field

[0001] This invention relates to the field of feeding equipment technology, and more specifically, to a reciprocating feeding mechanism. Background Technology

[0002] The existing feeding equipment is a long, straight conveyor line. Operators need to place materials—such as three-column housings—on the conveyor chain. However, due to space constraints, the conveyor line is limited in length, resulting in a small quantity that can be fed at a time. This necessitates repeated feeding, reducing production efficiency. Furthermore, during the material's movement, two parallel materials may jam, requiring operators to separate the jammed housings to restore normal flow. This unstable conveying requires constant monitoring of the parts' movement by the operators.

[0003] The existing conveying methods have the following drawbacks in actual use:

[0004] 1) The conveyor line is too long and occupies too much space. The existing conveyor line is a long straight conveyor line, which occupies a large space due to its excessive length.

[0005] 2) The number of materials that can be fed at one time is limited. The existing conveyor line can only feed about 15 materials at a time, which requires personnel to feed the materials repeatedly, which has a significant impact on production efficiency.

[0006] 3) Material jamming is prone to occur during the conveying process. In the existing conveyor line, two workpieces are easily squeezed and pushed against each other during the flow, causing them to get stuck and unable to be pushed. Operators need to separate them before the flow can continue, which affects production efficiency. Summary of the Invention

[0007] To address the problems of large space occupation and low feeding efficiency in feeding structures, this invention provides a reciprocating feeding mechanism, comprising:

[0008] Framework components;

[0009] A directional conveyor belt is disposed on the frame assembly for conveying materials to the worktable. The directional conveyor belt moves along the conveying direction, and the outer edge of the frame assembly is higher than the surface of the directional conveyor belt to confine the materials on the conveyor belt.

[0010] A deflector belt is disposed on the frame assembly, adjacent to the directional conveyor belt and located on the same plane, for conveying materials to the directional conveyor belt, and the deflector belt reciprocates along the conveying direction;

[0011] The width of the directional conveyor belt is 1.2 to 1.8 times the width of the material, and the width of the deflecting conveyor belt is 1.2 to 1.8 times the width of the material;

[0012] A chain plate is disposed at the end of the reversing conveyor belt in the forward direction to guide the material to move to the adjacent directional conveyor belt. The abutment plate on the chain plate that contacts the material is inclined so that the length of the reversing conveyor belt in the conveying direction gradually decreases from the side closer to the directional conveyor belt to the side farther away from the directional conveyor belt.

[0013] In some embodiments, the directional conveyor belt travels at a speed V along the conveying direction. 定 Not less than the speed V of the reversing conveyor belt moving along the conveying direction 变进 The speed V of the reversing conveyor belt moving along the conveying direction 变进 Not less than its backward speed V 变退 .

[0014] In some embodiments, the directional conveyor belt travels at a speed V along the conveying direction. 定 The speed V of the variable-direction conveyor belt moving along the conveying direction 变进 The relationship is: V 定 =1.1V 变进 The speed V of the reversing conveyor belt moving along the conveying direction 变进 Its backward speed V 变退 The relationship is: V 变进 =1.2V 变退 .

[0015] In some embodiments, the deflecting conveyor belt includes a first conveyor belt, a second conveyor belt, and a third conveyor belt distributed from one side close to the directional conveyor belt to the other side away from the directional conveyor belt.

[0016] In some embodiments, the speeds of the directional conveyor belt, the first conveyor belt, the second conveyor belt, and the third conveyor belt decrease sequentially along the conveying direction.

[0017] In some embodiments, the width of the directional conveyor belt is 1.5 times the width of the material, and the width of the deflecting conveyor belt is 1.5 times the width of the material.

[0018] In some embodiments, the abutment plate is a straight plate or an outwardly convex arc plate, and the outermost tangent line of the arc plate away from the directional conveyor belt has an angle greater than zero with the frame tail plate of the frame assembly.

[0019] In some embodiments, the abutment plate and the frame tail plate of the frame assembly are provided with an angle of 10° to 45°.

[0020] In some embodiments, a 35° angle is provided between the abutment plate and the frame tail plate of the frame assembly.

[0021] In some embodiments, the system further includes a first motor and a second motor. The first motor is connected to the directional conveyor belt and drives it to move forward along the conveying direction. The second motor is connected to the deflecting conveyor belt and drives it to reciprocate along the conveying direction.

[0022] The reciprocating feeding mechanism provided by this invention transports materials through the cooperation of a directional conveyor belt and a reversible conveyor belt. During the conveying process, the directional conveyor belt always moves forward to ultimately deliver the material to the operating table; while the reversible conveyor belt moves back and forth, alternating between forward and backward. A chain plate limits the furthest position the material can be conveyed on the reversible conveyor belt, and with the assistance of an inclined abutment plate, the reversible conveyor belt pushes the material onto the directional conveyor belt. By simultaneously setting up the directional conveyor belt and the adjacent reversible conveyor belt, the width of the conveying mechanism is increased, allowing it to accommodate more material at once. This significantly increases the material conveying capacity, avoids repeated loading, and improves loading efficiency. Furthermore, this arrangement reduces the length of the conveyor line, thereby saving space occupied by the feeding mechanism.

[0023] In addition, the widths of both the directional conveyor belt and the deflector belt are set to 1.2 to 1.8 times the width of the material. Therefore, the materials can be staggered during transport. Under the inclination of the abutment plate, the materials on the deflector belt will generate a mutual inward pushing force. Combined with the reciprocating motion of the deflector belt moving forward and backward, the continuous inward pushing force between the materials and the force of the conveyor belt can push the materials on the deflector belt to the adjacent directional conveyor belt. The above-mentioned solution of the present invention ensures that there is no jamming during the transport process, and more materials can be loaded at one time. It also eliminates the need for operators to be constantly on the production line, resulting in a large and efficient loading capacity and reducing the workload of operators.

[0032] This application provides a reciprocating feeding mechanism, including a frame assembly 10, a directional conveyor belt 20, a reversible conveyor belt 30, and a chain plate 40.

[0033] A directional conveyor belt 20 is mounted on the frame assembly 10 to transport materials to the operating table 14. The directional conveyor belt 20 advances in the conveying direction, and the outer edge of the frame assembly 10 is higher than the surface of the directional conveyor belt 20 to confine the materials on the conveyor belt, thereby preventing materials from falling off during conveying. Figure 1 As shown, the directional conveyor belt 20 is located on the side of the frame assembly 10 near the frame directional side plate 12. Its exposed length for placing materials extends from the frame tail plate 11 of the frame assembly 10 to the operating table 14, as shown. Figure 3 As shown.

[0034] A deflecting conveyor belt 30 is mounted on the frame assembly 10, adjacent to and in the same plane as the directional conveyor belt 20. It is used to transport materials onto the directional conveyor belt 20, thereby enabling the directional conveyor belt 20 to transport the materials to the operating table 14. During the conveying process, the deflecting conveyor belt 30 reciprocates along the conveying direction, that is, the deflecting conveyor belt 30 sometimes moves forward and sometimes backward. Figure 1 As shown, the deflecting conveyor belt 30 is positioned between the directional conveyor belt 20 and the deflecting side plate 13 of the frame assembly 10. One or more belts can be used, which reduces the length of the feeding mechanism's conveyor line and widens the conveying space, thereby increasing the single-pass material conveying capacity and improving conveying efficiency while avoiding an excessively long feeding mechanism. The directional side plate 12, the tail plate 11, and the deflecting side plate 13 of the frame assembly 10 are positioned around the outer periphery of the directional conveyor belt 20 and the deflecting conveyor belt 30, with a height higher than the material's center of gravity. This creates a material conveying space and prevents materials from falling out of the feeding mechanism during conveying. The deflecting conveyor belt 30 extends from the tail plate 11 of the frame assembly 10 to the abutment plate 41, extending beyond the frame assembly 10 to hold the material. Figure 3 As shown.

[0035] The chain plate 40 is located at the end of the deflecting conveyor belt 30 in the forward direction, and its contact plate 41, which contacts the material, is inclined, so that the length of the deflecting conveyor belt 30 in the conveying direction gradually decreases from the side closer to the directional conveyor belt 20 to the side farther away from the directional conveyor belt 20. Figure 1 As shown. Under the tilting action of the abutment plate 41, the materials on the deflecting conveyor belt 30 will generate a mutual pushing force. Combined with the reciprocating motion of the deflecting conveyor belt 30, which moves forward and backward, the continuous pushing force between the materials and the force of the conveyor belt can push the materials on the deflecting conveyor belt 30 to the adjacent directional conveyor belt 20. This arrangement, with the widened feeding space of the feeding structure, allows the materials to push and move towards the direction of the directional conveyor belt 20. Therefore, while increasing the conveying capacity, it ensures efficient and smooth feeding.

[0036] The width of the aforementioned directional conveyor belt 20 is 1.2 to 1.8 times the width of the material, and the width of the deflecting conveyor belt 30 is 1.2 to 1.8 times the width of the material. At this time, the directional conveyor belt 20 and the deflecting conveyor belt 30 can each accommodate one material in the width direction, and cannot accommodate two materials side by side. Therefore, during the conveying process, the materials can be kept in a staggered state, which facilitates the materials to enter the operating table 14 in sequence, avoids jamming during the conveying process, and makes the feeding more efficient.

[0037] In one embodiment of this application, the width of the directional conveyor belt 20 is 1.5 times the width of the material, and the width of the deflecting conveyor belt 30 is also 1.5 times the width of the material. This allows the material to be staggered more orderly on the conveyor belts, resulting in smoother movement. Of course, the widths of the directional conveyor belt 20 and the deflecting conveyor belt 30 can be set to be exactly the same, or different widths can be selected within the above range for conveying, all of which are within the protection scope of this application.

[0038] In a preferred embodiment of this application, the directional conveyor belt 20 moves at a speed V along the conveying direction. 定 Not less than the speed V of the reversing conveyor belt 30 moving in the conveying direction 变进 The speed V of the reversing conveyor belt 30 moving along the conveying direction 变进 Not less than its backward speed V 变退 This ensures that during the material conveying process, the directional conveyor belt 20 and the deflecting conveyor belt 30 have a certain speed difference, and the reciprocating motion of the deflecting conveyor belt 30 also has a certain speed difference, thereby creating a continuous internal thrust between the materials, which can continuously push them onto the directional conveyor belt 20.

[0039] In this embodiment, V 定 ≥V 变进 ≥V 变退 To ensure the stability of materials on the conveyor belts during transport and to prevent materials in simultaneous contact with both the directional conveyor belt 20 and the deflecting conveyor belt 30 from tipping over, it is necessary to consider the stability of materials on the V belt. 定 V 变进 and V 变退 The speed difference between the three is limited, preferably 1.2V. 变进 ≥V 定 ≥V 变进 1.35V 变退 ≥V 变进 ≥V 变退This speed difference setting enables sufficient pushing force between adjacent materials, thereby achieving continuous and stable pushing of materials from the deflecting conveyor belt 30 to the directional conveyor belt 20. Utilizing the speed difference between the directional conveyor belt 20 and the deflecting conveyor belt 30, and the speed difference of the deflecting conveyor belt 30 pushing forward and backward, the inclined abutment plate 41 allows materials near the deflecting side plate 13 of the frame to move onto the directional conveyor belt 20 through mutual inward pushing. This setting achieves the effects of no jamming during the conveying process, large-volume feeding, and labor saving.

[0040] Specifically, the speed V of the directional conveyor belt 20 moving along the conveying direction 定 The speed V of the reversing conveyor belt 30 moving in the conveying direction 变进 The relationship is: V 定 =1.1V 变进 The speed V of the reversing conveyor belt 30 moving along the conveying direction 变进 Its backward speed V 变退 The relationship is: V 变进 =1.2V 变退 At this point, the conveying and mutual pushing of materials become more stable. The aforementioned V 定 V 变进 and V 变退 Alternatively, the materials can be pushed to each other at the same speed, or two of them can be at the same speed. In this case, the materials can be pushed to each other by relying on the reciprocating motion of the deflecting conveyor belt 30 and the tilting action of the abutment plate 41.

[0041] As a preferred option, such as Figure 3 As shown, the deflecting conveyor belt 30 includes a first conveyor belt, a second conveyor belt, and a third conveyor belt distributed from the side closest to the directional conveyor belt 20 to the side furthest from the directional conveyor belt 20. Specifically, the first conveyor belt is adjacent to the directional conveyor belt 20, and the third conveyor belt is adjacent to the deflecting side plate 13 of the frame. Preferably, the speeds of the directional conveyor belt 20, the first conveyor belt, the second conveyor belt, and the third conveyor belt decrease sequentially along the conveying direction. Furthermore, when three deflecting conveyor belts 30 are provided, the length of the feeding mechanism can be significantly reduced, the feeding width can be greatly increased, and more materials can be conveyed simultaneously, thus resulting in greater conveying efficiency.

[0042] Furthermore, the forward speeds of the first, second, and third conveyor belts are each greater than their corresponding backward speeds, and the backward speeds of the first, second, and third conveyor belts decrease sequentially. This maintains the speed difference between adjacent conveyor belts, thereby ensuring a more continuous, stable, and efficient thrust between materials. Of course, the number of deflecting conveyor belts 30 can be specifically set according to the actual space and material size; this application does not impose any specific limitations.

[0043] This embodiment sets up multiple parallel conveyor belts. By reasonably controlling the forward and backward speeds of the conveyor belts, the width of the conveyor belts, and setting an inclined angle at the front end, it can be ensured that the materials are not jammed during the conveying process. By increasing the width and reducing the length, space is also saved, and the amount of materials that can be loaded at one time can be increased. The smooth conveying process avoids the problem of personnel having to keep an eye on the work, allowing operators to go to other processes to solve other problems, thereby improving production efficiency and saving labor.

[0044] In this embodiment of the application, an angle of 10° to 45° is provided between the abutment plate 41 and the frame tail plate 11 of the frame assembly 10, such as... Figure 3 As shown. This tilt range allows the material to be better propelled toward the directional conveyor belt 20 during transport. Preferably, a 35° angle is set between the abutment plate 41 and the frame tail plate 11 of the frame assembly 10 to make the material propulsion smoother and more efficient.

[0045] In a preferred embodiment of this application, the abutment plate 41 can be configured as a straight plate or a convex arc-shaped plate. When configured as a straight plate, the structure is as follows: Figure 2 and Figure 4 As shown, the material gradually approaches the frame tail plate 11 from one end near the directional conveyor belt 20 to the end of the frame deflector side plate 13, thereby allowing the material to be propelled towards one side of the directional conveyor belt 20 along the inclined direction under the action of mutual pushing force. Preferably, the straight plate and the frame deflector side plate 13 are connected by an arc-shaped smooth connection. During the conveying process, in order to avoid the material from getting stuck at the connection and being difficult to move, the arc of the arc connection can be set to an arc with a diameter not less than the maximum width of the material, or a certain number of circular protrusions can be set at the arc connection to reduce the friction between the material and the plate, so that it has a certain rolling force at the connection, thereby assisting the material to move quickly and efficiently.

[0046] When configured as an arc-shaped plate, the arc-shaped plate has an outward convex structure. This outward convexity refers to the outward convexity towards the material placement space, and towards the frame directional side plate 12 and the frame tail plate 11. Furthermore, a non-zero angle is formed between the outer tangent of the arc-shaped plate near the frame deflection side plate 13 and the frame tail plate 11, ensuring the inclination of the abutment plate 41 and preventing material from getting stuck and affecting conveying. In a preferred embodiment, the angle between the outer tangent of the arc-shaped plate and the frame tail plate 11—referring to an acute angle—gradually increases from the end near the frame deflection side plate 13 to the end away from it. This configuration makes the material on the deflection conveyor belt 30 increasingly smooth and efficient as it moves towards the directional conveyor belt 20.

[0047] The reciprocating feeding mechanism of this application also includes a first motor 50 and a second motor 60. The first motor 50 is connected to the directional conveyor belt 20 and drives it to move forward along the conveying direction. The second motor 60 is connected to the deflecting conveyor belt 30 and drives it to reciprocate along the conveying direction. Of course, in addition to the second motor 60, other structures capable of reciprocating motion, such as connecting rods or cylinders, can also be used to drive the deflecting conveyor belt 30 to move forward and backward, with motors being the most suitable.

[0048] In addition, a control device is included, which can control the first motor 50 and the second motor 60. If the power unit is another structure instead of a motor, the control device can also perform control. By controlling the power unit, the forward and backward speeds of the directional conveyor belt 20 and the deflecting conveyor belt 30 can be adjusted, as well as the forward and backward duration of the deflecting conveyor belt 30, thereby making adaptive adjustments according to different material conditions to make the feeding process more efficient.

[0049] The reciprocating feeding mechanism provided in this embodiment transports materials through the cooperation of a directional conveyor belt 20 and a deflecting conveyor belt 30. During the transport process, the directional conveyor belt 20 always moves forward to ultimately deliver the material to the operating table 14; while the deflecting conveyor belt 30 reciprocates, sometimes moving forward and sometimes backward. The chain plate 40 limits the farthest position of the material transported on the deflecting conveyor belt 30, and with the cooperation of the inclined abutment plate 41, the deflecting conveyor belt 30 pushes the material on it onto the directional conveyor belt 20. By setting up the directional conveyor belt 20 and the adjacent deflecting conveyor belt 30, the width of the conveying mechanism is increased, allowing it to accommodate more materials simultaneously. Therefore, the material transport capacity is greatly increased, repeated loading is avoided, and the loading efficiency is improved. Furthermore, the above arrangement can reduce the length of the conveyor line, thereby saving space occupied by the feeding mechanism.

[0050] Furthermore, the widths of both the directional conveyor belt 20 and the deflecting conveyor belt 30 are set to 1.2 to 1.8 times the width of the material. Therefore, the materials can be staggered during transport, preventing two parallel conveyors from causing jamming and affecting subsequent transport. Under the tilting action of the abutment plate 41, the materials on the deflecting conveyor belt 30 will generate mutual inward pushing forces. Combined with the reciprocating motion of the deflecting conveyor belt 30, which moves forward and backward, the continuous inward pushing force between the materials and the force of the conveyor belt can push the materials on the deflecting conveyor belt 30 to the adjacent directional conveyor belt 20. The above-mentioned solution in this embodiment ensures that there is no jamming during the transport process, and more materials can be loaded at once. It also eliminates the need for operators to constantly monitor the production line, resulting in large and efficient material loading and reducing the workload of operators.

[0051] See Figure 2 and Figure 4This is a schematic diagram of the feeding process when the material is a three-column shell. At this time, the material placement space is the area provided by the entire conveyor belt. It can be seen that it can accommodate more three-column shells at the same time. The material on the deflecting conveyor belt 30 located between the frame tail plate 11 and the abutment plate 41 is pushed to the directional conveyor belt 20 under the action of the pushing force. Driven by the directional conveyor belt 20, it is transported to the operating table 14 through the channel between the frame directional side plate 12 and the chain plate 40 side plate opposite to the frame directional side plate 12. The whole conveying process is smoother and more efficient, while greatly reducing the workload of the operator.

[0052] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
