Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of bolt processing and conveying equipment, specifically a conveying device for multi-station bolt processing. Background Technology
[0002] The industrial production of bolts typically involves multiple processing stages, such as wire straightening, cold heading, thread rolling, and inspection and screening. The processing equipment at each stage operates independently, necessitating the transfer of semi-finished bolts between processes. Taking the inspection and screening station after thread rolling as an example, after the bolts are processed by the thread rolling machine, they usually fall directly from the discharge port into a collection box, and are then manually transported by workers to the loading station of the inspection equipment (such as an optical sorting machine). However, this manual handling method has the following drawbacks:
[0003] 1. Increased labor intensity for workers: Workers need to frequently move bolts, which is not only inefficient, but also prone to fatigue during mass production, affecting production stability;
[0004] 2. Discontinuous transmission process: Due to the intermittent nature of manual handling, bolts cannot be continuously and automatically conveyed, making it difficult to match the production rhythm between different workstations and affecting overall production efficiency. Furthermore, if the bolts in the collection box are poured into the vibratory feeder of the testing equipment all at once after handling, the vibratory feeder will be overloaded due to the excessive instantaneous discharge, which will affect the sorting effect of the subsequent workstations. If the bolts are poured in intermittently, workers need to repeatedly lift the collection box, which greatly increases the workload of workers. Utility Model Content
[0005] This utility model provides a transmission device for multi-station bolt processing, which can solve the technical problems of low transmission efficiency and poor continuity of production and transportation in existing multi-station processing.
[0006] This application provides the following technical solution:
[0007] A multi-station bolt processing transmission device includes a feeding channel and a conveyor belt. The feeding channel is located between the discharge port of the thread rolling machine and the feed port of the conveyor belt. The feeding channel is inclined downwards, and the conveyor belt is inclined upwards. The discharge port of the conveyor belt is located at the feed end of the inspection station. Side plates are provided on both sides of the conveyor belt, and several partitions are provided on the upper surface of the conveyor belt. The bottom plate of the feeding channel is grid-shaped, and a fan is also provided on the feeding channel. The fan is inclined upwards to blow away the debris carried by the bolts.
[0008] Beneficial effects:
[0009] 1. By setting up a feeding channel and conveyor belt, the threaded bolts are automatically and continuously transported to the testing station, eliminating the traditional manual handling method, significantly reducing the labor intensity of workers, avoiding fatigue caused by frequent handling, and ensuring production stability. Simultaneously, it achieves continuous automated transport of bolts from the thread rolling machine to the testing equipment, effectively matching the production rhythm of each station and significantly improving overall production efficiency. Furthermore, because the conveyor belt stably and continuously transports bolts to the loading station of the testing equipment, it avoids the problem of overloading the vibratory feeder at the loading station caused by manually dumping a large number of bolts at once, ensuring the sorting effect of subsequent stations, and eliminating the need for workers to repeatedly operate the collection box, further reducing the workload of workers.
[0010] 2. After thread rolling, the surface of the bolt will carry some debris or coolant. If the debris is not removed, it may affect the accuracy of the subsequent automatic screening of the bolt using an optical inspection instrument. Therefore, by setting the bottom plate of the feeding channel to a grid shape and installing a fan on the feeding channel, debris is removed and waste liquid is dried during the process of conveying the bolt to the conveyor belt. This effectively ensures the cleanliness of the bolt surface, avoids debris or residual coolant interfering with the detection results of the optical inspection instrument, improves the accuracy and reliability of bolt inspection, and ensures the precision of product quality inspection.
[0011] 3. The blower is angled upwards to dry the bolts and remove any debris, allowing it to fall off the grid base plate. It also slows the bolts' descent, extending their time in the feeding channel and giving the blower more time to clean them, ensuring thorough removal of debris and waste liquid. Furthermore, it reduces the impact of the bolts hitting the conveyor belt, minimizing surface damage and ensuring product quality. This allows the bolts to land more smoothly on the conveyor belt, facilitating subsequent transport and improving overall stability.
[0012] Furthermore, a collection box for collecting debris is provided at the bottom of the feeding channel, and a flared hood is provided at the top of the collection box, with the upper edge of the hood abutting against the bottom edge of the base plate.
[0013] Beneficial effects: The grid-like base plate allows debris blown off by the fan to fall smoothly, and the flared hood can expand the collection range, allowing debris to fall accurately into the collection box, avoiding debris from scattering around the equipment or other work areas, reducing the accumulation of debris on the workshop floor and in equipment gaps, and effectively improving the workshop production environment.
[0014] Furthermore, there are two sets of fans, which are respectively installed on the left and right side walls at the lower end of the material feeding channel, and the air outlets of the fans are tilted upwards.
[0015] Beneficial effects: Two sets of fans blow air from both sides of the feeding channel, forming a cross-shaped inclined airflow. During the bolt's descent, this airflow exerts forces on the debris in multiple directions, accelerating the debris from the bolt surface and causing it to fall downwards, achieving more comprehensive cleaning. In addition, the airflow generated by the two sets of fans acts on the bolt from different directions, which helps the bolt maintain a relatively stable posture during its descent, reducing surface damage caused by collisions and tumbling, while also preventing the bolt from being directly ejected from the conveyor belt due to excessive falling speed.
[0016] Furthermore, the feeding channel has a U-shaped structure, and protective pads are installed on the left and right side walls of the feeding channel.
[0017] Beneficial effects: The protective pad protects the bolt, preventing it from colliding significantly with the inner wall of the feed channel after the thread rolling is completed. This avoids scratches and other damage to the bolt surface, ensuring that the bolt's appearance and dimensional accuracy meet production standards and effectively improving product quality.
[0018] Furthermore, the discharge port of the feeding channel is also equipped with an inwardly converging feeding pipe, and the discharge port of the feeding pipe is located directly above the conveyor belt.
[0019] Beneficial effect: The inward-converging feed pipe gathers and guides the falling bolts, concentrating the originally scattered bolts to the center of the conveyor belt and preventing them from deviating from the conveyor belt when they fall.
[0020] Furthermore, the conveyor belt is a chain-plate track conveyor belt.
[0021] Beneficial effects: The surface structure of the chain plate provides significant friction for the bolts, effectively preventing them from slipping during transport even when the conveyor belt runs at an incline, ensuring that the bolts are accurately and smoothly delivered to the inspection station.
[0022] Furthermore, the high-end frame of the conveyor belt is equipped with a downward-sloping guide plate, and the outlet of the guide plate is located directly above the feed end of the inspection station.
[0023] Furthermore, the feeding end of the inspection station is equipped with a vibratory feeder for sorting and feeding materials, and the discharge port of the guide plate is located above the vibratory feeder.
[0024] Beneficial effects: The guide plate provides a clear guiding path for the bolts output from the conveyor belt, accurately guiding the bolts to the feed end directly above the inspection station. This prevents the bolts from deviating from the predetermined landing point due to the inertia of the conveyor belt or their own gravity, ensuring that the bolts can enter the vibratory feeder accurately, reducing the need for manual secondary adjustments, and improving the level of production automation and the accuracy of feeding.

[0028] The following detailed description illustrates the specific implementation method:
[0029] The markings in the attached drawings of the instruction manual include: feeding channel 1, side wall 11, protective pad 111, feeding pipe 12, conveyor belt 2, side plate 21, partition 22, protrusion 23, fan 3, collection box 4, cover opening 41, guide plate 5, wire rolling machine 100, and vibratory plate 200.
[0030] Example
[0031] like Figure 1 As shown, a multi-station bolt processing transmission device includes a feeding channel 1 and a conveyor belt 2. The feeding channel 1 is located between the discharge port of the thread rolling machine 100 and the feed port of the conveyor belt 2. The feeding channel 1 is inclined downwards, and the conveyor belt 2 is inclined upwards, with the discharge port of the conveyor belt 2 located at the feed end of the inspection station. Figure 2 As shown, side plates 21 are provided on both sides of the conveyor belt 2, and several partitions 22 are provided on the upper surface of the conveyor belt 2. The partitions 22 are used to ensure that the bolts do not slide down when they are conveyed upward.
[0032] Specifically, in this embodiment, the conveyor belt 2 is an existing chain-plate track conveyor belt, and the surface of the conveyor belt 2 is also provided with a number of protrusions 23 for anti-slip purposes; such as Figure 1 As shown, the high-end frame of the conveyor belt 2 is also equipped with a guide plate 5 that is inclined downward. The guide plate 5 is detachably connected to the frame by bolts. The discharge port of the guide plate 5 is located directly above the feed end of the inspection station. In this embodiment, the feed end of the inspection station is equipped with a vibratory feeder 200 for sorting and feeding. After sorting by the vibratory feeder 200, the bolts are orderly transported to the inspection station for optical inspection.
[0033] like Figure 3As shown, the bottom plate of the feeding channel 1 is grid-shaped, and a blower 3 is also installed on the feeding channel 1. The blower 3 is inclined upward to blow away the debris carried by the bolt. Specifically, there are two sets of blowers 3, which are respectively installed on the left and right side walls 11 at the lower end of the feeding channel 1. The air outlets of the blowers 3 are inclined upward. The two sets of blowers 3 blow air from both sides of the feeding channel 1 to form a cross-shaped inclined airflow. During the bolt falling, it will exert forces on the debris in multiple directions, accelerating the debris to detach from the bolt surface and fall from the grid, so as to achieve more comprehensive cleaning. In addition, the airflow generated by the two sets of blowers 3 acts on the bolt from different directions, which can keep the bolt in a relatively stable posture during the falling process, reduce surface damage caused by collision and tumbling, and prevent the bolt from directly rushing into the conveyor belt 2 due to excessive falling speed.
[0034] The feeding channel 1 has a U-shaped structure, and protective pads 111 are provided on the left and right side walls 11 of the feeding channel 1. The protective pads 111 protect the bolts and prevent them from colliding with the inner wall of the feeding channel 1 after the thread rolling is completed. The discharge port of the feeding channel 1 is also welded with an inwardly converging feeding pipe 12. The discharge port of the feeding pipe 12 is located directly above the conveyor belt 2. The inwardly converging feeding pipe 12 gathers and guides the falling bolts, concentrating the originally scattered bolts to the center of the conveyor belt 2.
[0035] like Figure 1 As shown, in this embodiment, the bottom of the feeding channel 1 is also provided with a collection box 4 for collecting debris. The top of the collection box 4 is provided with a funnel-shaped hood 41, and the upper edge of the hood 41 abuts against the bottom edge of the base plate. The grid-like base plate allows the debris blown off by the fan 3 to fall smoothly. The funnel-shaped hood 41 can expand the collection range, allowing the debris to fall accurately into the collection box 4, avoiding debris from scattering around the equipment or other working areas, reducing the accumulation of debris on the workshop floor and in the gaps of the equipment, and effectively improving the workshop production environment.
[0036] During use, the bolts rolled by the thread rolling machine 100 fall onto the feeding channel 1. As the bolts fall along the feeding channel 1, the fan 3 generates an upward airflow within the feeding channel 1, thereby removing debris and waste liquid carried by the bolts. This effectively ensures the cleanliness of the bolt surface and prevents debris or residual coolant from interfering with the detection results of the optical inspection instrument. Subsequently, under the action of gravity, the bolts continue to enter the feeding pipe 12 along the feeding channel 1 and fall from the feeding pipe 12 onto the conveyor belt 2, where they are transported to the vibrating plate 200 at the inspection station.
[0037] This application utilizes a feeding channel 1 and a conveyor belt 2 to automatically and continuously transport threaded bolts to the testing station, eliminating the need for traditional manual handling, significantly reducing worker fatigue, preventing fatigue from frequent handling, and ensuring production stability. Simultaneously, it achieves continuous automated transport of bolts from the thread rolling machine 100 to the testing equipment, effectively matching the production rhythm of each station and significantly improving overall production efficiency. Furthermore, because the conveyor belt 2 stably and continuously transports bolts to the loading station of the testing equipment, it avoids the overload problem of the vibratory feeder 200 at the loading station caused by manually dumping a large number of bolts at once, ensuring the sorting effect of subsequent stations and eliminating the need for workers to repeatedly operate the collection box, further reducing worker workload.
