Description

Technical Field

[0001] This utility model relates to the field of linear feeder technology, specifically to a linear feeder cyclic feeding mechanism. Background Technology

[0002] Commonly used linear feeders have problems with small materials, such as single-row needles, getting stuck or leaking. This is especially noticeable at the turning points of the circulating material selection, which seriously affects on-site use. Switching to a bulk vibratory feeder can eliminate this problem, but this feeder is bulky and noisy, which is not accepted by customers. Summary of the Invention

[0003] In order to overcome the shortcomings of existing technical solutions, this utility model provides a linear feeder with a circulating feeding mechanism, which can effectively solve the problem of small material jamming and leakage proposed in the background technology.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a linear feeder circulating feeding mechanism, including a feeding module, a conveying module and a collecting module arranged in sequence; The feeding module includes: An upwardly inclined feed conveyor belt; An openable top cover covering the feed conveyor belt is hinged to the mechanism housing via a hinge; The feed inlet and baffle structure are provided at the starting end of the feed conveyor belt, and the baffle is located below the feed inlet; The conveying module includes: Two parallel and staggered screening conveyor belts; An arc-shaped guide plate is installed at the end of the screening conveyor belt; Air blowing devices are respectively installed at the beginning and end of the screening conveyor belt; The collection module includes: The receiving seat is connected to the conveyor module via a track; Material baffles are installed on the receiving seat and arranged on both sides along the material's direction of travel; A fixed seat and a limiting post are provided at the end of the receiving seat, and the limiting post is inserted into the upper part of the fixed seat; Through-beam photoelectric sensors are installed on both sides of the baffle plate.

[0005] Furthermore, the screening conveyor belt includes a horizontal conveyor belt and an upward conveyor belt.

[0006] Furthermore, the horizontal conveyor belt and the upward conveyor belt are driven by a first motor and a second motor, respectively.

[0007] Furthermore, the track is a detachable structure.

[0008] Furthermore, the top cover is a transparent cover plate.

[0009] Furthermore, the inclination angle of the feed conveyor belt is 15° to 40°, and its surface is provided with anti-slip texture.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This invention employs two parallel and staggered screening conveyor belts. Through the reasonable spacing design between the conveyor belts, the jamming phenomenon of small materials during the conveying process can be effectively reduced.

[0011] The curved guide plate allows the material movement direction to change smoothly, avoiding material jamming or splashing caused by right-angle turns.

[0012] Air blowing devices are installed at both the beginning and end of the screening conveyor belt. The air blowing device at the beginning can blow off materials that are not in the correct position or are messy, preventing material jamming; the air blowing device at the end can help the materials turn around faster, ensuring smooth entry into the next stage.

[0013] The airflow pressure of the blowing device is adjustable, which can precisely control the airflow for small materials of different weights and sizes, avoiding the material from scattering due to excessive airflow or failing to blow effectively due to insufficient airflow.

[0014] Through-beam photoelectric sensors detect the material's position in real time, ensuring that each material accurately enters the predetermined position and avoiding material jamming caused by positional deviation.

[0015] The limiting post at the end of the receiving seat can effectively block the material from moving forward and prevent the material from rushing out of the receiving seat area due to inertia, causing the material to fall.

[0016] By using two conveyor belts arranged in an alternating pattern and with the help of curved guide plates, the material can be circulated and screened during the conveying process, allowing for continuous processing of a large number of small materials and significantly increasing the screening quantity per unit time.

[0017] The air blowing device can quickly separate qualified and unqualified materials, reduce manual intervention time, and improve overall screening efficiency.

[0018] The modular design of the feeding module, conveying module, and collection module allows for flexible combination and expansion according to actual production needs, such as increasing the number of conveyor belts or adjusting the layout of the air blowing device to accommodate larger batch screening tasks.

[0019] The track has a detachable structure, which facilitates the quick replacement and position adjustment of the receiving seat to meet the collection needs of small materials of different sizes.

[0020] The feeding conveyor belt is inclined upwards, and with the baffle structure, the feeding speed of the material can be effectively controlled, avoiding the obstruction of the conveyor due to material accumulation and ensuring the continuity of the screening process.

[0021] The baffles on both sides of the receiving seat and the limiting post at the end work together to ensure that the materials are neatly arranged during the collection process, reducing the decrease in screening efficiency caused by disordered arrangement. Attached Figure Description

Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this disclosure.

[0026] like Figure 1-4 As shown, this utility model provides a linear feeder circulating feeding mechanism, including a feeding module, a conveying module and a collecting module arranged in sequence; The feeding module includes: An upwardly inclined feed conveyor belt; An openable top cover covering the feed conveyor belt is hinged to the mechanism housing via a hinge; The feed inlet and baffle structure are provided at the starting end of the feed conveyor belt, and the baffle is located below the feed inlet to prevent the material from sliding down; The conveying module includes: Two parallel and staggered screening conveyor belts; The arc-shaped guide plate located at the end of the screening conveyor belt is used to guide the material to change its direction of movement and turn around. Air blowing devices are respectively installed at the beginning and end of the screening conveyor belt. The air blowing device at the beginning is used to blow off materials that are not in the correct posture or are messy, while the air blowing device at the end is used to assist materials to turn around more quickly. The collection module includes: The receiving seat is connected to the conveyor module via a track; Material baffles are installed on the receiving seat and arranged on both sides along the material's direction of travel; A fixed seat and a limiting post are provided at the end of the receiving seat. The limiting post is inserted into the upper part of the fixed seat to block the material from moving forward. Through-beam photoelectric sensors installed on both sides of the baffle plate are used to detect the material's arrival status.

[0027] This invention employs two parallel and staggered screening conveyor belts. Through the reasonable spacing design between the conveyor belts, the jamming phenomenon of small materials during the conveying process can be effectively reduced.

[0028] The curved guide plate allows the material movement direction to change smoothly, avoiding material jamming or splashing caused by right-angle turns.

[0029] Air blowing devices are installed at both the beginning and end of the screening conveyor belt. The air blowing device at the beginning can blow off materials that are not in the correct position or are messy, preventing material jamming; the air blowing device at the end can help the materials turn around faster, ensuring smooth entry into the next stage.

[0030] The airflow pressure of the blowing device is adjustable, which can precisely control the airflow for small materials of different weights and sizes, avoiding the material from scattering due to excessive airflow or failing to blow effectively due to insufficient airflow.

[0031] Through-beam photoelectric sensors detect the material's position in real time, ensuring that each material accurately enters the predetermined position and avoiding material jamming caused by positional deviation.

[0032] The limiting post at the end of the receiving seat can effectively block the material from moving forward and prevent the material from rushing out of the receiving seat area due to inertia, causing the material to fall.

[0033] By using two conveyor belts arranged in an alternating pattern and with the help of curved guide plates, the material can be circulated and screened during the conveying process, allowing for continuous processing of a large number of small materials and significantly increasing the screening quantity per unit time.

[0034] The air blowing device can quickly separate qualified and unqualified materials, reduce manual intervention time, and improve overall screening efficiency.

[0035] The modular design of the feeding module, conveying module, and collection module allows for flexible combination and expansion according to actual production needs, such as increasing the number of conveyor belts or adjusting the layout of the air blowing device to accommodate larger batch screening tasks.

[0036] The track has a detachable structure, which facilitates the quick replacement and position adjustment of the receiving seat to meet the collection needs of small materials of different sizes.

[0037] The feeding conveyor belt is inclined upwards, and with the baffle structure, the feeding speed of the material can be effectively controlled, avoiding the obstruction of the conveyor due to material accumulation and ensuring the continuity of the screening process.

[0038] The baffles on both sides of the receiving seat and the limiting post at the end work together to ensure that the materials are neatly arranged during the collection process, reducing the decrease in screening efficiency caused by disordered arrangement.

[0039] See Figure 4 The screening conveyor belt includes a horizontal conveyor belt and an upward conveyor belt. The beginning and end of the staggered conveyor belts form a drop, and the material is circulated and screened by blowing it down through a blowing device. The horizontal and upward conveyor belts are arranged in an alternating manner, so that the material forms a natural drop at the junction of the two conveyor belts. When the material falls from the end of the horizontal conveyor belt, the blowing device blows down the material that does not meet the requirements, while the qualified material continues to move upward with the upward conveyor belt, thereby realizing the automatic circulation and screening of the material.

[0040] See Figure 4 The horizontal conveyor belt and the upward conveyor belt are driven by a first motor and a second motor, respectively. Through independent driving, the speed of the horizontal conveyor belt and the upward conveyor belt can be adjusted separately, controlling the residence time of the material on the conveyor belt, extending the screening path, and giving the air blowing device more time to sort the material, thereby increasing the screening quantity per unit time.

[0041] The track is a detachable structure, which allows for easy adjustment of the track length and layout according to material specifications to adapt to different scenarios.

[0042] The top cover is a transparent cover, allowing users to directly observe the material inside the equipment without having to open it frequently.

[0043] The feed conveyor belt has an inclination angle of 15° to 40° and its surface is provided with anti-slip texture.

[0044] In this embodiment of the application, the material is cyclically screened. By adjusting the sheet metal, the gap between the sheet metal and the belt is reduced, and the guiding of the sheet metal on the belt is reduced. Instead, the material is dropped and connected naturally, so as to avoid jamming and dropping.

[0045] During operation, the feeding belt rotates to feed and screen materials. Materials of suitable orientation are fed forward, while materials of unsuitable orientation fall to the bottom of the circulating belt. The belt rotates backward and upward, moving the materials backward and upward. A slanted sheet metal block is welded below the end point of the belt to ensure that the materials fall onto the sheet metal. By tilting and blowing air, the circulating materials are sent onto the feeding belt, achieving the effect of circulating material selection.
