Description
Technical Field
[0001] This utility model relates to the technical field of needle tooth feeding equipment, and more specifically, to a needle tooth feeding device applied to a needle tooth grinding device. Background Technology
[0002] In the production and processing of needle teeth, grinding is a crucial step that ensures the surface quality and dimensional accuracy of the teeth to meet subsequent usage requirements. However, existing needle tooth feeding methods have several problems.
[0003] Generally, needles are fed using a conveyor belt and then transported to the grinding device for the grinding process. Traditional feeding devices only have a conveying function, and the needles are prone to different placement states during transport, such as tilting, inversion, or stacking. Needles in a disordered placement state are collectively referred to as defective products or substandard needles. If substandard needles in a disordered placement state are directly fed to the grinding device, it will cause uneven grinding, damage to the needles, and other problems. Furthermore, disordered needles tend to accumulate at the grinding device inlet, affecting the grinding effect and production efficiency. Manually intervening to place the needles evenly and orderly before conveying them is inefficient and will seriously affect the efficiency of subsequent production steps.
[0004] On the other hand, existing feeding devices are unable to accurately count the number of pins entering the grinding device, making it difficult to reasonably arrange production schedules, calculate production costs, and ensure product quality stability, which brings inconvenience to production management and quality control.
[0005] Therefore, there is a need for a needle feeding device that can effectively solve the above problems in order to improve the production efficiency and product quality of the needle grinding process. Utility Model Content
[0006] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a needle tooth feeding device for use in needle tooth grinding equipment. This needle tooth feeding device for needle tooth grinding equipment has efficient needle tooth conveying and sorting functions, and can accurately count the number of needle teeth entering the grinding equipment, thereby improving the production efficiency and product quality of the needle tooth grinding process.
[0007] To achieve the above objectives, this utility model adopts the following technical solution:
[0008] A needle tooth feeding device for use in a needle tooth grinding device includes a material box, a transmission structure is provided on the top of one side of the outer wall of the material box, and a feeding component is provided on the inner wall of the material box near the transmission structure. The feeding component is used to move the needle teeth in the material box from bottom to top to the transmission structure.
[0009] The transmission structure is provided with a return component and a counting component in sequence along the travel path of the needle teeth;
[0010] The reflux assembly is installed between the hopper and the conveying structure to recycle defective pins from the conveying structure back into the hopper.
[0011] The counting component is mounted on the transmission structure, and the hopper is also provided with a drive structure for moving the transmission structure and the feeding component.
[0012] Furthermore, the feeding assembly includes multiple push plates and fixed plates, with each push plate and fixed plate corresponding to the other. The tops of the push plates and fixed plates are inclined downwards from the side away from the transmission structure to the side closer to the transmission structure, and the push plates move up and down along the inner wall of the material box.
[0013] Furthermore, the top surfaces of both the push plate and the fixing plate are inclined from the end closer to the return assembly to the end farther away from the return assembly.
[0014] Furthermore, the transmission structure is provided with a first baffle, on which an L-shaped baffle is detachably fixed. The L-shaped baffle includes a straight plate connected to the first baffle and a side plate perpendicular to the straight plate. The side plate is coplanar with one side of the material box.
[0015] Furthermore, the reflux assembly includes a reflux channel and a first limiting block; the reflux channel includes a slide plate and a third baffle; the first limiting block is "L"-shaped, and one side of the first limiting block is fixed to the first baffle, and the third baffle and the side of the first limiting block away from the first baffle are on the same plane.
[0016] Furthermore, one end of the return channel is connected to the transmission structure, and the other end is connected to the material box. The return channel is located on the side of the material box away from the side plate.
[0017] Furthermore, a fourth baffle is provided on the first limiting block.
[0018] Furthermore, the first limiting block is provided with an installation groove, and the fourth baffle is connected to the installation groove via a slider, and the slider can slide back and forth in the installation groove.
[0019] Furthermore, the counting component includes multiple sets of telescopic plates, which are driven to extend and retract by a drive cylinder.

[0027] The present invention will be further described below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the present invention. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.
[0028] Example 1
[0029] like Figure 1-3As shown, the needle feeding device for a needle grinding apparatus provided by this utility model includes a material box 1. A transmission structure 2 is provided on the top of one side of the outer wall of the material box 1. A feeding component 3 is provided on the inner wall of the material box 1 near the transmission structure 2. The feeding component 3 is used to move the needles in the material box 1 from bottom to top to the transmission structure 2. A return component 4 and a counting component 5 are sequentially provided on the transmission structure 2 along the travel path of the needles. The return component 4 is installed between the material box 1 and the transmission structure 2 to collect unqualified needles on the transmission structure 2 back into the material box 1. The counting component 5 is installed on the transmission structure 2 to detect the number of needles entering the needle grinding apparatus. The material box 1 is also provided with a drive structure for driving the transmission structure 2 and the feeding component 3 to move.
[0030] The feeding component 3 rapidly conveys the needle teeth from bottom to top to the transmission structure 2, achieving continuous feeding of the needle teeth and avoiding the tediousness and inefficiency of manual feeding. At the same time, the return component 4 can promptly screen out needle teeth with unqualified posture and recycle them. Only needle teeth with qualified posture can enter the needle tooth grinding device through the return component 4, reducing downtime and adjustment time of the grinding device caused by needle tooth posture problems and improving overall production efficiency. The counting component 5 can accurately count the number of needle teeth entering the needle tooth grinding device, providing important data support for production management. Operators can reasonably arrange production plans, calculate production costs, and promptly detect abnormalities in the production process based on the counting data, achieving precise control of the production process. This needle tooth feeding device integrates the material box 1, transmission structure 2, feeding component 3, return component 4, and counting component 5 into one compact structure with a small footprint. At the same time, the drive structure can simultaneously drive the transmission structure 2 and the feeding component 3 to move, making operation simple and convenient and reducing the labor intensity of operators.
[0031] Furthermore, in another embodiment, the feeding assembly 3 includes a plurality of push plates 301 and fixed plates 302, the push plates 301 and fixed plates 302 corresponding one to one, the top ends of the push plates 301 and fixed plates 302 tilt downward from the side away from the transmission structure 2 to the side closer to the transmission structure 2, and the push plates 301 move up and down along the inner wall of the material box 1.
[0032] In practical applications, multiple push plates 301 and fixed plates 302 are located on the inner wall of the material box 1 near the conveying structure 2. The multiple push plates 301 and fixed plates 302 correspond one-to-one, that is, the push plates 301 and fixed plates 302 are alternately arranged. During operation, the fixed plate 302 is fixed and the push plates 301 move up and down. The needle teeth are first pushed from the bottom of the material box to the top surface of the fixed plate 302 by the lifting and lowering movement of the push plates 301, and then moved from the top surface of the fixed plate 302 to the top surface of another push plate 301. The feeding component 3 conveys the needle teeth to the conveying structure 2 through the above reciprocating motion. The tops of the push plates 301 and fixed plates 302 tilt downward from the side away from the conveying structure 2 to the side closer to the conveying structure 2. The needle teeth are transported towards the conveying structure 2 by natural guidance, reducing manual intervention and avoiding material accumulation at the edge of the material box 1. At the same time, it can adapt to different material densities and flowability to ensure stable material supply.
[0033] Furthermore, the top surfaces of the push plate 301 and the fixing plate 302 are inclined from the end closer to the return component 4 to the end farther away from the return component 4; the inclination angle of the top surfaces of the push plate 301 and the fixing plate 302 is 15°, or it can be 20°.
[0034] The top surfaces of the push plate 301 and the fixed plate 302 are inclined at 15°-20°. When the push plate 301 moves upward and pushes the pins from the bottom of the material box to the fixed plate 302, some pins that are upright will tilt to one end due to the inclined design, becoming parallel to the push plate 301 or the fixed plate 302, or fall into the material box 1. This corrects some pins with incorrect posture and improves the working efficiency of the entire production line.
[0035] Furthermore, in another embodiment, the transmission structure 2 is provided with a first baffle 201, and an L-shaped baffle 202 is detachably fixed on the first baffle 201. The L-shaped baffle 202 includes a straight plate connected to the first baffle 201 and a side plate 2021 perpendicular to the straight plate. The side plate 2021 is coplanar with one side of the material box 1. The first baffle 201 and the L-shaped baffle 202 can restrict the position of the needle teeth when the needle teeth move to the transmission structure 2.
[0036] When the needle teeth are transported from the feeding assembly 3 to the transmission structure 2, the first baffle 201 and the L-shaped baffle 202 constrain the needle teeth from different directions, jointly constructing a limiting space. This restricts the needle teeth to a certain range on the transmission structure 2, ensuring that the needle teeth move on the transmission structure 2 according to the preset path and direction, guaranteeing processing quality and conveying effect, and improving work accuracy and quality. Moreover, the design of the side plate 2021 of the L-shaped baffle 202 being coplanar with one side of the material box 1 not only saves space occupied by the device, but also makes the connection between various components more compact and orderly, further improving the overall performance and working efficiency of the device.
[0037] Furthermore, in another embodiment, the reflux assembly 4 includes a reflux channel 401 and a first limiting block 402; the first limiting block 402 is fixed on the first baffle 201; the reflux channel 401 includes a sliding plate and a third baffle 403; the first limiting block 402 is "L"-shaped, and one side of the first limiting block 402 is fixed on the first baffle 201, and the third baffle 403 and the side of the first limiting block 402 away from the first baffle 201 are on the same plane.
[0038] The first limiting block 402 is fixedly connected to the first baffle 201. The distance between the first limiting block 402 and the transmission structure 2 is greater than the diameter of the needle teeth but less than twice the diameter of the needle teeth. That is, by setting the first limiting block 402, the needle teeth are only allowed to pass laterally. Needles that are upright or stacked upwards are blocked by the first limiting block 402 and return to the material box 1 through the slide plate of the return channel 401. At the same time, by setting the third baffle 403, and the third baffle 403 is on the same plane as the first limiting block 402, the recycling path of the needle teeth can be precisely controlled, reducing the number of incorrectly positioned needle teeth entering the grinding device. This not only improves the working efficiency and stability of the entire device, but also reduces the probability of needle teeth getting stuck, extends the service life of the device, and reduces maintenance costs.
[0039] Furthermore, in another embodiment, one end of the return channel 401 is connected to the transmission structure 2 and the other end is connected to the material box 1. The return channel 401 is located on the side of the material box 1 away from the side plate 2021.
[0040] Furthermore, in another embodiment, the first limiting block 402 is provided with a fourth baffle 404, which is used to block the horizontally arranged needle teeth so that the needle teeth enter the grinding device one by one in sequence.
[0041] When horizontally arranged pin teeth enter the grinding device, the fourth baffle 404 blocks excess pin teeth, allowing only one pin tooth to enter the grinding area horizontally in sequence. This not only reduces interference and collision between pin teeth, avoiding uneven grinding or equipment failure caused by pin tooth accumulation or misalignment, but also improves the accuracy of the equipment. Furthermore, it makes the pin tooth grinding process more automated and controllable, reducing the need for manual intervention, thereby improving production efficiency and reducing labor costs.
[0042] Furthermore, in another embodiment, the first limiting block 402 has a mounting groove 4021, and the fourth baffle 404 is connected to the mounting groove 4021 via a slider 4041, which can slide back and forth within the mounting groove 4021. Through the cooperation of the slider 4041 and the sliding groove 4021, the fourth baffle 404 can be stably connected to the first limiting block 402 and slide along the trajectory of the sliding groove 4021 to adapt to different needle tooth sizes, enhancing its adaptability and versatility. It also facilitates installation and disassembly, making it easy to replace fourth baffles 404 of different sizes.
[0043] Furthermore, in another embodiment, the counting component 5 includes multiple sets of telescopic plates 501, which are driven to extend and retract by a drive cylinder 502. The drive cylinder 502 is located on the side of the transmission structure 2 near the material box 1. The counting component 5 is also equipped with a counting sensor, which counts the number of needle teeth that pass through by detecting the number of times the telescopic plates 501 extend and retract.
[0044] The drive cylinder 502 is installed on the side of the transmission structure 2 near the material box 1 to ensure that the needle teeth can be effectively counted during the transmission process. When the needle teeth pass through the counting component, it will trigger the extension and retraction of the telescopic plate 501. Each extension and retraction is counted by the counting sensor to calculate the number of needle teeth that have passed. This not only realizes the automatic counting of the number of needle teeth, but also accurately captures the extension and retraction of the telescopic plate 501 through the counting sensor, effectively avoiding counting errors caused by human factors or environmental factors, and improving the accuracy and reliability of counting.
[0045] Furthermore, in another embodiment, the counting component 5 may also be a telescopic rod or a lever.
[0046] Working Principle: The material bin 1 serves as a storage container for the pins, containing the pins to be ground. After the drive structure is activated, it drives the feeding assembly 3 to start working. The feeding assembly 3 moves the pins at the bottom of the material bin 1 from bottom to top to the transmission structure 2. After reaching the transmission structure 2, the pins move forward along the travel path. When passing the return assembly 4, the return assembly 4 detects the posture of the pins. If the posture of the pins is not qualified, such as standing upright or piling up, the return assembly 4 will separate these pins with unqualified posture from the transmission structure 2 and collect them back into the material bin 1 to ensure that the pins entering the pin grinding device are all in the correct posture, thus improving the grinding quality. After the posture screening, the pins continue to move on the transmission structure 2. When they reach the counting assembly 5, the counting assembly 5 will detect and count the pins that have passed through.
