Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of track plate heat treatment, and more specifically, to a feeding device for track plate heat treatment. Background Technology

[0002] In the field of construction machinery, track shoes are core components that withstand strong impacts and high loads, and their performance directly determines the reliability and service life of the equipment. Heat treatment is a key process to improve the strength and wear resistance of track shoes, and the feeding device, as the starting point of the heat treatment process, has a crucial impact on production efficiency and product quality.

[0003] Currently, most track plate heat treatment production lines use traditional feeding devices, which typically rely on manual assistance or simple mechanical structures for material conveying. In practical applications, traditional feeding devices have significant drawbacks: firstly, manual feeding is inefficient, labor-intensive, and difficult to ensure consistent feeding positions each time, leading to uneven heating of the track plates in the heat treatment equipment and affecting product quality stability; secondly, some automated feeding devices, due to insufficient positioning accuracy, are prone to track plate misalignment and jamming, not only reducing equipment operating efficiency but also potentially causing equipment failures or safety accidents. Furthermore, traditional devices lack the ability to adaptively adjust to track plates of different specifications, failing to meet diverse production needs.

[0004] Therefore, there is an urgent need to design a feeding device for heat treatment of track plates that can accurately control the feeding position and improve production efficiency and product quality, so as to solve the problems existing in the current technology. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a feeding device for heat treatment of track plates, which solves the technical problems of low efficiency, high labor intensity and difficulty in ensuring the consistency of feeding position each time in the prior art, resulting in uneven heating of track plates in heat treatment equipment and affecting the stability of product quality.

[0007] The equipment frame and several conveying rollers are rotatably connected inside the equipment frame;

[0008] An inlet and a feeding conveying assembly, wherein the inlet is formed on the side surface of the equipment frame and the feeding conveying assembly is mounted on the equipment frame;

[0009] The sliding plate and the pushing assembly are provided, wherein the sliding plate is fixed to the side end face of the equipment frame and the pushing assembly is disposed at one end inside the equipment frame;

[0010] The feeding and conveying assembly includes a pair of side baffles, which are fixed to the side surface of the equipment frame and located on both sides of the inlet. A discharge plate is rotatably connected to the inlet via a pin. A connecting rod is provided on the side surface of the equipment frame, and a cylinder is rotatably connected to the bottom surface of the discharge plate via a pin at one end of the connecting rod.

[0011] As a further technical solution, a main shaft is provided on one side of the equipment frame. The main shaft is driven to rotate by electricity. Several drive gears are provided on the main shaft, and several of the conveying rollers are provided with driven gears at one end. The driven gears mesh with the drive gears.

[0012] As a further technical solution, the pushing assembly includes a pair of positioning plates, which are disposed on both sides inside the equipment frame. The positioning plates are connected to the side surface of the equipment frame by a linear drive, and one end of the positioning plate is rotatably connected to the pushing plate via a rotating shaft.

[0013] As a further technical solution, the pusher plate is driven to rotate by electricity, a slide rod is provided on the side surface of the positioning plate, the slide rod is slidably fitted inside the side surface of the equipment frame, the positioning plate is 90° opposite to the conveying roller, and a baffle that is driven to rotate by electricity is provided inside the equipment frame, the lower end face of the baffle is attached to the surface of the pusher plate.

[0014] As a further technical solution, both the sliding plate and the baffle have a certain tilt angle.

[0015] As a further technical solution, a number of rolling rods are rotatably connected inside the equipment frame. The rolling rods are located between adjacent conveying rollers, and the upper end face of the rolling rod is at the same height as the upper end face of the conveying roller.

[0016] As a further technical solution, the surface of the feeding plate is higher than the upper surface of the conveying roller and the rolling rod.

[0017] As a further technical solution, several of the driving gears and the driven gears are all bevel gears.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. In this disclosure, the feeding and conveying assembly solves the problems of low efficiency and inconsistent positioning of manual feeding through the cooperation of side baffles, discharge plates, and conveying rollers. The side baffles ensure that the track plates do not deviate when sliding down, the angle adjustment of the discharge plate controls the sliding speed, and the conveying rollers rotate at a uniform speed under gear transmission, achieving smooth conveying and avoiding jamming in conjunction with the rolling rods. This design eliminates the need for manual handling, reduces labor intensity, and ensures consistent conveying position of the track plates, laying the foundation for subsequent accurate feeding and improving production efficiency and stability.

[0020] 2. In this disclosure, the pushing assembly achieves precise positioning and pushing of the track plates through the coordinated action of the positioning plate, the pushing plate, and the baffle, solving the problem of uneven heating caused by deviations in the feeding position. The positioning plate adjusts the position of the track plates in the center, the pushing plate pushes the track plates in a directional manner, the baffle precisely limits the movement, and the inclined design of the sliding plate assists the material in entering the equipment. The cooperation of each component ensures that the track plates are fed in the same position each time, resulting in uniform heating during heat treatment, improving product quality stability, and adapting to different specifications of track plates, thus enhancing the versatility of the device.

[0032] like Figures 1-3 As shown, it illustrates a feeding device for heat treatment of track plates according to an embodiment of the present disclosure, comprising:

[0033] The equipment frame 1 and several conveying rollers are rotatably connected inside the equipment frame 1.

[0034] The inlet 3 and the feeding conveying assembly 5 are provided. The inlet 3 is opened on the side surface of the equipment frame 1, and the feeding conveying assembly 5 is disposed on the equipment frame 1.

[0035] The sliding plate 4 and the pushing assembly 6 are provided. The sliding plate 4 is fixed to the side end face of the equipment frame 1, and the pushing assembly 6 is disposed at one end inside the equipment frame 1.

[0036] The feeding and conveying assembly 5 includes a pair of side baffles 5-1, which are fixed to the side surface of the equipment frame 1. The side baffles 5-1 are located on both sides of the inlet 3. A discharge plate 5-2 is rotatably connected to the inlet 3 via a pin. A connecting rod 5-3 is provided on the side surface of the equipment frame 1. A cylinder 5-4 is rotatably connected between one end of the connecting rod 5-3 and the bottom surface of the discharge plate 5-2 via a pin. A main shaft 5-5 is provided on one side of the equipment frame 1. The main shaft 5-5 is driven to rotate by electricity. Several drive gears 5-6 are provided on the main shaft 5-5. One end of several conveying rollers is provided with a driven gear 5-7, which meshes with the drive gears 5-6.

[0037] In some examples, in order to achieve a stable feeding and conveying effect, a feeding and conveying assembly 5 is designed. This assembly includes a pair of side baffles 5-1 on both sides of the inner surface of the equipment frame 1, which are symmetrically fixed on both sides of the inlet 3 and can provide lateral limiting for the track plates. The discharge plate 5-2 inside the inlet 3 is rotatably connected by a pin and can be flexibly flipped. The bottom surface of the discharge plate 5-2 is rotatably connected to the connecting rod 5-3 on the side surface of the equipment frame 1 by a pin and a cylinder 5-4. The extension and retraction of the cylinder 5-4 can drive the discharge plate 5-2 to rotate and adjust the tilt angle to control the track plates to slip.

[0038] The main shaft 5-5 on one side of the equipment frame 1 is electrically driven (e.g., by a motor). Several drive gears 5-6 on the main shaft mesh with driven gears 5-7 at one end of some of the conveyor rollers. When the main shaft 5-5 rotates, it drives the conveyor rollers to rotate synchronously through gear transmission. The conveyor rollers cooperate with each other to stably convey the track plates that slide off the discharge plate 5-2 forward. The side baffle 5-1, discharge plate 5-2, cylinder 5-4, and conveyor rollers work together to realize the process of the track plates sliding off and being smoothly conveyed, providing a stable material supply for subsequent processing.

[0039] like Figures 1-3 As shown in the figure, the pusher assembly 6 in this embodiment includes a pair of positioning plates 6-1. The positioning plates 6-1 are disposed on both sides inside the equipment frame 1. The positioning plates 6-1 are connected to the side surface of the equipment frame 1 by a linear drive. One end of the positioning plate 6-1 is rotatably connected to a pusher plate 6-2 by a rotating shaft. The pusher plate 6-2 is rotated by electric drive. A slide rod 6-3 is provided on the side surface of the positioning plate 6-1. The slide rod 6-3 is slidably fitted inside the side surface of the equipment frame 1. The positioning plate 6-1 is 90° opposite to the conveying roller. A baffle 6-4 is provided inside the equipment frame 1 and is rotated by electric drive. The lower end face of the baffle 6-4 is attached to the surface of the slide plate 4.

[0040] In some examples, to achieve the desired feeding effect, a pusher assembly 6 is designed. This assembly includes positioning plates 6-1 on both sides inside the equipment frame 1, which are connected to the side surface of the equipment frame 1 via a linear drive device. A slide rod 6-3 on the side surface of the 6-1 slides within the side surface of the equipment frame 1, ensuring stable translation of the positioning plates 6-1. A pusher plate 6-2 at one end of the positioning plate 6-1 is rotatably connected via a rotating shaft and is electrically driven, allowing for angle adjustment.

[0041] The baffle 6-4 inside the equipment frame 1 is electrically driven to rotate, and its lower end face is attached to the surface of the sliding plate 4, which can prevent the track plate from moving further and accurately position it. When the track plate is conveyed to the designated position, the linear drive drives the positioning plate 6-1 to move towards the center, centering the track plate. Then, the pusher plate 6-2 rotates and pushes the track plate along the sliding plate 4 into the heat treatment equipment. The cooperation of all components ensures that the track plate enters the heat treatment equipment accurately, improving the feeding accuracy.

[0042] For example, such as Figure 1 As shown, both the sliding plate 4 and the baffle 6-4 have a certain tilt angle.

[0043] In some examples, the tilt angles of the sliding plate 4 and the baffle 6-4 are matched. The tilt of the sliding plate 4 guides the track plate to slide towards the heat treatment equipment under gravity, while the tilt of the baffle 6-4 precisely blocks the track plate, stopping it at a preset position before it is pushed. The matching angles of the two ensure smooth conveying and accurate positioning, thus improving pushing efficiency.

[0044] For example, such as Figure 1 As shown, a plurality of rolling rods 7 are rotatably connected inside the equipment frame 1. The rolling rods 7 are located between adjacent conveying rollers, and the upper end face of the rolling rod 7 is at the same height as the upper end face of the conveying roller.

[0045] In some examples, the rolling rod 7 within the equipment frame 1 is rotatably connected between adjacent conveyor rollers, with its upper end face flush with the conveyor rollers. The rolling rod 7 rotates as the track plates move, reducing friction at the bottom of the track plates and preventing jamming during conveying. At the same time, the rolling rod 7 fills the gaps between the conveyor rollers, preventing the edges of the track plates from getting stuck, ensuring smooth conveying, and adapting to track plates of different specifications.

[0046] For example, such as Figure 1 As shown, the plane of the feeding plate 5-2 is higher than the upper surface of the conveying roller and the rolling rod 7.

[0047] In some examples, the surface of the feed plate 5-2 is higher than the upper surfaces of the conveyor rollers and the rolling rods 7. This design allows the track plates to move smoothly from the feed plate 5-2 onto the conveyor assembly using the inertia generated by the height difference, avoiding stagnation. At the same time, the height difference, combined with the tilt angle of the feed plate 5-2, can control the sliding speed of the track plates, ensuring orderly entry into the conveying process.

[0048] For example, such as Figure 1 As shown, several of the driving gears 5-6 and the driven gears 5-7 are all bevel gears.

[0049] In some examples, the driving gear and driven gear 5-7 are bevel gears, which mesh perpendicularly to transmit power. Bevel gears can change the transmission direction to adapt to the spatial layout of the main shaft 5-5 and the conveyor rollers. They offer high meshing accuracy and smooth transmission, ensuring consistent conveyor roller speeds, allowing the track plates to be conveyed at a uniform speed, and reducing positional deviations caused by speed fluctuations.

[0050] In actual use: The track plate is placed on the feeding plate 5-2, and the side baffles 5-1 on both sides restrict its lateral displacement. The cylinder 5-4 is activated to extend and retract, causing the feeding plate 5-2 to rotate around the pin shaft, so that the track plate slides down the feeding plate 5-2 onto the conveyor roller. The electric drive spindle 5-5 rotates, and through the meshing of the drive gear 5-6 and the driven gear 5-7, it drives the conveyor roller to rotate. The track plate moves forward with the conveyor roller. The rolling rods 7 between adjacent conveyor rollers provide auxiliary support to prevent jamming. When the track plate touches the baffle 6-4, it stops moving. The linear drive pushes the positioning plate 6-1 to move towards the center along the slide bar 6-3 to center and position the track plate. The pusher plate 6-2 rotates and pushes it onto the sliding plate 4. The baffle 6-4 rotates to release the track plate, and the track plate enters the heat treatment equipment along the inclined sliding plate 4, completing the feeding process.
