Abstract
Description
Technical Field
[0001] This application relates to the field of chain guiding technology for chain conveyor equipment, and in particular to an auxiliary tool for guiding and positioning the chain of a chain feeder. Background Technology
[0002] Chain feeders, as a common type of continuous conveying equipment, are widely used in material conveying systems in industries such as mining, metallurgy, chemicals, and building materials. Their core working principle involves driving a conveyor chain through a drive gear, thereby achieving directional material transport.
[0003] However, during long-term continuous operation, the chain is prone to lateral swaying or deviation due to factors such as load, vibration, transmission inertia, and external disturbances. Traditional chain guiding mechanisms mostly use fixed guide plates or rigid block structures to restrict the chain displacement through mechanical constraints. Although such structures can maintain the chain's running trajectory to a certain extent, the high-frequency vibration and slight swaying of the chain during operation will continuously rub against the fixed guiding structure, leading to accelerated wear on the chain sidewalls and guide contact surfaces. This not only shortens the equipment's lifespan but also requires frequent maintenance and replacement.
[0004] As wear accumulates, the gap between the chain and the guide structure gradually increases, the guiding accuracy decreases, the chain swing amplitude increases further, and it may even cause failures such as chain derailment or jamming.
[0005] In other words, existing technologies have the following technical problems: ordinary chain guiding devices are prone to continuous friction damage from contact with the chain during operation. Therefore, to address the above problems, a chain guiding and positioning auxiliary tool for chain feeders is proposed. Summary of the Invention
[0006] This embodiment provides a chain guide and positioning auxiliary tool for a chain feeder to solve the problem that ordinary chain guide devices in the prior art are prone to continuous friction damage during chain operation due to contact with the chain.
[0007] According to one aspect of this application, a chain guide and positioning auxiliary tool for a chain feeder is provided, comprising: a rotating shaft, with transmission gears fixedly connected to both ends of the rotating shaft, and a conveyor chain sleeved on the transmission gears, wherein the transmission gears and the conveyor chain mesh with each other;
[0008] A fixed bracket is provided on the rotating shaft, and the rotating shaft and the fixed bracket are rotatably connected. A support part is fixedly connected to the upper surface of the fixed bracket, and a positioning component is fixedly connected to the top of the support part.
[0009] The positioning component consists of a rectangular fixed base and a movable positioning part, which is used to contact the conveyor chain and limit the movement of the conveyor chain.
[0010] Furthermore, the positioning component consists of a movable plate, a positioning rod, and a positioning sleeve. The movable plate is disposed on the upper surface of the rectangular fixed base and slides with the rectangular fixed base. The positioning rod is fixedly connected to the upper surface of the movable plate, and the positioning sleeve is rotatably sleeved on the outer surface of the positioning rod.
[0011] Furthermore, a plurality of balls are fitted and rotatably disposed on the inner wall of the positioning sleeve, and the balls are in contact with the outer surface of the positioning rod.
[0012] Furthermore, the rectangular fixing seat has a sliding groove cavity inside, and movable sliders are slidably connected to both sides of the sliding groove cavity of the rectangular fixing seat, and the movable sliders are fixedly connected to the movable plate.
[0013] Furthermore, a fixed guide rod is fixedly connected to the inner wall of the rectangular fixed seat, and the fixed guide rod passes through the movable slider and slides with the movable slider.
[0014] Furthermore, one end of a limiting spring is fixedly connected to the side wall of the movable slider, and the other end of the limiting spring is fixedly connected to the inner wall of the rectangular fixed seat.
[0015] Furthermore, a damping component is also provided at the movable slider, which is used to provide damping and buffering during movement.
[0016] Furthermore, the damping component is composed of a friction damping block and a spring plate. The movable slider has an internal cavity, in which the friction damping block is slidably connected. One end of the spring plate is fixedly connected to one side of the friction damping block, and the other end of the spring plate is fixedly connected to the inner wall of the movable slider.
[0017] Furthermore, the end face of the friction damping block is configured as an arc surface that mates with the fixed guide rod. The friction damping block contacts the surface of the fixed guide rod and is pressed together by a spring sheet.
[0018] In order to solve the problem in the prior art that the chain guiding mechanism of a conventional chain feeder is damaged due to continuous friction between the fixed guiding structure and the guiding structure during the long-term movement and oscillation of the chain, resulting in insufficient guiding effect, this application designs a positioning component. Through the movable positioning part on the positioning component, the chain can be guided and limited at the same time, and a slight displacement can be generated with the oscillation of the chain during the oscillation, and the large oscillation of the chain can be suppressed. While ensuring the normal guidance of the chain, the phenomenon of continuous friction damage between the chain and the guiding mechanism caused by vibration and oscillation can be reduced.

[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.
[0028] Please see Figure 1-6As shown, a chain guide and positioning auxiliary tool for a chain feeder includes: a rotating shaft 1, with transmission gears 2 fixedly connected to both ends of the rotating shaft 1, and a conveying chain 3 sleeved on the transmission gears 2, wherein the transmission gears 2 and the conveying chain 3 mesh with each other;
[0029] A fixed bracket 4 is provided on the rotating shaft 1, and the rotating shaft 1 and the fixed bracket 4 are rotatably connected. A support part 5 is fixedly connected to the upper surface of the fixed bracket 4, and a positioning component 6 is fixedly connected to the top of the support part 5.
[0030] The positioning component 6 consists of a rectangular fixed base 601 and a movable positioning part. The positioning part is used to contact the conveyor chain 3 and limit the movement of the conveyor chain 3.
[0031] To address the problem in existing chain feeders where the chain guiding mechanism suffers damage due to continuous friction between the fixed guiding structure and the chain during prolonged oscillation, leading to increased gaps and insufficient guiding effect, this application designs a positioning component 6. The movable positioning parts on the positioning component 6 can simultaneously guide and limit the chain while also allowing for slight displacement as the chain oscillates, suppressing large-scale chain oscillations. This ensures proper chain guidance while mitigating the continuous friction damage caused by vibration and oscillation between the chain and the guiding mechanism.
[0032] The positioning component consists of a movable plate 602, a positioning rod 603, and a positioning sleeve 604. The movable plate 602 is disposed on the upper surface of the rectangular fixed base 601 and slides with the rectangular fixed base 601. The positioning rod 603 is fixedly connected to the upper surface of the movable plate 602, and the positioning sleeve 604 is rotatably sleeved on the outer surface of the positioning rod 603.
[0033] The inner wall of the positioning sleeve 604 is fitted with a plurality of balls 605 that rotate in a rotatable manner. The balls 605 contact the outer surface of the positioning rod 603. Through this technical solution, the setting of the balls 605 can make the rotation of the positioning sleeve 604 smoother. When in contact with the surface of the conveyor chain 3, they can effectively play a rolling role and avoid damage caused by continuous friction with the chain.
[0034] The rectangular fixing base 601 has an internal sliding groove cavity. Movable sliders 606 are slidably connected to both sides of the sliding groove cavity of the rectangular fixing base 601. The movable sliders 606 are fixedly connected to the moving plate 602. Through this technical solution, the movable sliders 606 guide the sliding of the moving plate 602, preventing skewing during movement and making the positioning component's constraint on the chain more stable. Furthermore, the cross-section of the sliding groove cavity of the rectangular fixing base 601 is rectangular or T-shaped, and the shape of the movable sliders 606 matches this shape to prevent twisting during movement.
[0035] A fixed guide rod 607 is fixedly connected to the inner wall of the rectangular fixed base 601. The fixed guide rod 607 passes through the movable slider 606 and slides with the movable slider 606.
[0036] One end of a limiting spring 608 is fixedly connected to the side wall of the movable slider 606, and the other end of the limiting spring 608 is fixedly connected to the inner cavity wall of the rectangular fixed seat 601. Preferably, the limiting spring 608 is a stainless steel compression spring, and its elastic coefficient is designed according to the chain tension and expected offset force, typically ranging from 50 to 200 N / mm. The spring preload is adjustable to adapt to the chain limiting requirements under different working conditions. Through this technical solution, the position of the moving slider 606 can be positioned by the setting of the limiting spring 608, and the position of the positioning part can also be positioned, so that the positioning part is located on both sides of the conveyor chain 3. When the conveyor chain 3 deviates, the positioning sleeve 604 acts as a limiting guide through the blocking effect. When the conveyor chain 3 deviates slightly, the lateral force generated by the deviation of the conveyor chain 3 can act on the positioning sleeve 604, thereby overcoming the initial elastic force of the limiting spring 608, so that the positioning sleeve 604 deviates slightly by a certain distance to adapt to the vibration deviation of the conveyor chain 3 and avoid damage caused by long-term continuous squeezing and friction. When the conveyor chain 3 deviates significantly, the lateral force generated by the deviation of the conveyor chain 3 can no longer overcome the elastic force of the limiting spring 608, so that the conveyor chain 3 can no longer deviate, thus playing a limiting and positioning role and ensuring the guiding role of the conveyor chain 3 during its movement.
[0037] A damping component is also provided at the movable slider 606, which is used to provide damping and buffering during movement.
[0038] The damping component consists of a friction damping block 609 and a spring plate 610. The movable slider 606 has an internal cavity. The friction damping block 609 is slidably connected in the internal cavity of the movable slider 606. One end of the spring plate 610 is fixedly connected to one side of the friction damping block 609. The other end of the spring plate 610 is fixedly connected to the inner wall of the movable slider 606.
[0039] The end face of the friction damping block 609 is set as an arc surface that cooperates with the fixed guide rod 607. The friction damping block 609 contacts the surface of the fixed guide rod 607 and is pressed together by the spring plate 610. Through this technical solution, the friction damping block 609 can play a role in friction damping. During the movement of the moving slider 606, friction plays a damping and buffering role, thereby further suppressing vibration, reducing reciprocating swaying, and improving the positioning effect of the conveyor chain 3.
[0040] Specifically, the positioning components 6 are symmetrically arranged on both sides of the conveyor chain 3, with at least one set of positioning components on each side to form a guide channel, effectively limiting the horizontal displacement of the chain.
[0041] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.
[0042] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
