[0031] The use principle of the present invention;

[0032] This production line is mainly composed of a sandblasting machine body 1, a lifting and dumping feeding mechanism 2, a discharging conveying mechanism 3, a vibrating screening mechanism 4 and a multi-station full inspection conveying mechanism 5. The overall design is segmented and continuous, and each segment specifically adopts an inclined forward structure. The lifting and dumping feeding mechanism 2 is used for front-end feeding of the sandblasting machine body 1. Mechanical parts enter the sandblasting machine body 1 through the lifting and dumping feeding mechanism 2. After the sandblasting process, they enter the discharging conveying mechanism 3. The discharging conveying mechanism 3 transports the mechanical parts to the vibrating screening mechanism 4. After the paving separation of the vibrating screening mechanism 4, they are transported to the multi-station full inspection conveying mechanism 5. Finally, the staff conducts quality inspection, turnover and other operations on the mechanical parts through the multi-station full inspection conveying mechanism 5.

[0033] It should be noted that: the design reference point of this production line is the inlet and outlet of the sandblasting machine body 1. The size range of the inlet is matched by the lifting and tilting height of the lifting and tilting feeding mechanism 2. If the height is less than 1.3m, it is advisable to adopt a one-stage lifting and tilting, and if it exceeds 1.3m, it is advisable to adopt a two-stage lifting and tilting. Under the premise that the size of the outlet (normally about 800mm) is fixed, considering the smoothness of the production line and the drop of each part (the maximum drop of the curvature radius R100 of the transmission belt roller should not be less than 100mm), if each section normally adopts a planar design with a staged drop, the height of the full inspection conveyor belt at the end of the production line will be too low (less than 600mm), causing the operator's operating surface to be too low whether standing or sitting, which does not conform to the habit of visual inspection and the physiological function of the human body. In order to overcome this drawback, the height of the assembly line is designed as a jumping forward mode, that is, the discharging conveying mechanism 3, the vibrating screening mechanism 4 and the multi-station full-inspection conveying mechanism 5 all adopt an inclined design, that is, the conveyor belt A306 of the discharging conveying mechanism 3 is from low to high; the vibrating screen 403 of the vibrating screening mechanism 4 is from high to bottom; the conveyor belt B506 of the multi-station full-inspection conveying mechanism 5 is from low to high; this inclined design realizes the perfect connection of each segmented space and a high degree of functional fit.

[0034] See also Figure 2In a normal state, the inner material box 203 of the lifting and dumping feeding mechanism 2 is located below the outer tilting frame 202; at the same time, the tilting cylinder 206 is in a retracted state, and the lifting cylinder 207 is in an extended state. The operator transports the material to the inner material box 203 through a transportation tool, and the remote control operates the lifting cylinder 207 to operate, and the cylinder contracts to lift the inner material box 203 to the inside of the outer tilting frame 202, that is, to the first level height; when reaching the predetermined position, the inner material box 203 will touch the configured limit switch, and the limit switch generates a signal and notifies the tilting cylinder 206 to operate, and the tilting cylinder 206 begins to extend, thereby driving the outer tilting frame 202 and the inner material box 203 to tilt together, and the angle can be greater than or equal to 60 degrees, and the parts in the inner material box 203 are then dumped downstream into the hopper of the sandblasting machine body 1.

[0035] The lifting and dumping feeding mechanism 2 can be adapted to multiple models of sandblasting machine bodies 1, and has high adaptability. Whether to use the secondary lifting structure can be appropriately selected according to the height of the feed port of the sandblasting machine body 1. If the height is less than 1.3m, the inner material box 203 and the lifting cylinder 207 can be omitted, and the outer tilting frame 202 can be directly placed on the ground (with a 10mm iron plate on the bottom), and the material turnover box can be pushed in manually.

[0036] The dimensions of the inner material box 203 are 1150mm long*800mm wide*1000mm high, and it is highly adaptable to accommodating existing material turnover boxes. The conventional turnover weight of conventional mechanical hydraulic carts and forklifts is 500kg-1000kg, and the dimensions are usually ≤1000mm in length, ≤700mm in width, and ≤700mm in height. If the dimensions are too large and the weight is too heavy, it is not easy to take into account the feed port of the sandblasting machine body 1 when directly using conventional mechanical hydraulic carts and forklifts.

[0037] Since the inner material box 203 is heavy and high after loading, in order to ensure safety, it is operated by a long-distance remote control, abandoning the traditional relay button control, and adopting a six-way wireless receiving controller. The power supply is Dc-12-36V, and the receiving sensitivity is higher than -105dbm; and the cylinder load is 500-1000kg. In order to ensure high safety and work efficiency, the cylinder adopts D80-B type, and the oil pump power is greater than or equal to 5.5kw; at the same time, the tilting angle of the outer tilting frame 202 and the inner material box 203 is large, ≥60 degrees, the material is poured thoroughly, and the work efficiency is high.

[0038] In order to improve the strength and rigidity of the outer tilting frame 202 and the inner material box 203 and reduce their own weight, the outer tilting frame 202 mainly uses No. 10 channel steel as the skeleton and is covered with 6mm iron plate, and the inner material box 203 mainly uses 10mm iron plate welded into a single-sided open basket box type. The outer tilting frame 202 and the inner material box 203 are conveniently connected by the guide rail 208 for sliding connection, thereby achieving smooth contact without jamming, and the structure has higher strength, more reasonable force, and more convenient maintenance, making it stronger and more durable.

[0039] There are one tilt cylinder 206 and one lift cylinder 207 on the left and right sides, and each inlet and outlet pipe of the hydraulic oil circuit is divided into two paths. It is easy to cause unbalanced load, resulting in asynchronism of the two cylinders in a set of actions, which is specifically manifested as uneven force on the left and right sides of a set of cylinders, and the hydraulic cylinders vibrate and tremble. In order to solve this problem, a hydraulic synchronous motor is added to the hydraulic oil circuit, model selection: SHxy-2R-4.2S. Through the use of hydraulic synchronization technology, the on-site problems of the equipment are well solved, the operation effect is very stable, and the effect is ideal.

[0040] See also Figure 3 and Figure 4 In order to facilitate the discharge and receiving of the sandblasting machine body 1, the discharge conveying mechanism 3 adopts the design of side receiving, and the width is as wide as possible. The bearing surface is ≥600mm, the length is 3m, and it matches the conventional sandblasting machine body 1. Among them, the slope of the conveyor belt A306 is 1:15, and the conveyor belt A306 is designed to be forward and reverse, which can prevent blockage during discharge. The matching drive motor A304 is 1.5kw, the reduction ratio i=29 and the linear speed is 30m / min. In order to reduce flying dust and improve the on-site environment, the conveyor belt A306 adopts a closed design: that is, the single-sided guard plate is fixed, and the guard plate on the easy-to-operate side can be removed, which is convenient for cleaning sand leakage and maintenance; at the same time, in order to extend the service life of the conveyor belt A306, reduce the impact of the falling parts on the belt and rollers, and improve the force structure, the roller A305 adopts a high-density close-distance design on the upper layer and a sparse and long-distance arrangement on the lower layer. Combined with the actual spatial structure layout, the drive motor A304 is set above the conveyor belt A306 to facilitate the tightness adjustment and equipment maintenance of the conveyor belt A306; and according to the load and force structure of the conveyor belt A306, the conveyor belt A306 adopts B600*t10, 6 rubber 5 wire (full inspection conveyor belt B500*t10). Therefore, the curvature radius of the transmission roller A302 is too small to make it difficult for the conveyor belt to bend, and the use of D200 can also take into account the spatial installation of the roller A305.

[0041] See also Figure 5 and Figure 6, combined with the actual production situation, the vibrating screening mechanism 4 adopts a dustpan type, and its vibrating screen 403 adopts a polarization structure, that is, the vibrating screen 403 is an inclined structure that gradually decreases along the feeding direction; the model of the vibration motor 405 is selected as ZFB-9-0.75kw, the exciting force is 15KN, the vibration frequency is 3000 times / min, and the vibration motor 405 is installed at the high end of the vibrating screen 403. This design is not only conducive to maintenance, but also conducive to generating the reciprocating force of the forward circulating feeding, which effectively improves the vibration screening effect; the vibrating screen 403 is surrounded by a closed and detachable guard plate, which is dust-proof and convenient for maintenance and disassembly. The vibrating screen 403 has a slope of 1:10 and a sand leakage hole is designed at the bottom, which is conducive to vibration discharging and easy to completely separate the steel sand powder particles. It should be noted that the vibration damping spring 402 is designed with a limited dust cover; due to the high vibration frequency of the vibration motor 405, the vibrating screening mechanism 4 is easy to change position, and the frame B401 of the vibrating screening mechanism 4 can be fixed to the ground with expansion bolts.

[0042] See also Figure 7 The multi-station full inspection conveyor mechanism 5 is controlled by the control console 509 to match the material discharging speed of the vibrating screen 403 and the full inspection speed of the operator. The conveyor belt B506 adopts a variable frequency speed regulation design, and the speed of the conveyor belt B506 can be adjusted in real time. Among them, the conveyor belt B506 is 6m long, and the conveyor belt B506 is designed to be forward and reverse, so as to prevent the inspection from being missed due to excessive speed at startup or in the early stage, so that it can be returned for inspection in real time according to the site. As conveyor belt B506 is relatively long and requires a large amount of power, a 4kw cycloidal pinwheel drive motor B504 is used, which has a compact bottom layer layout and model number Xwd-4-i17; conveyor belt B506 has a height of 750-950mm, which is a relatively suitable height for both standing and sitting positions according to the height of a normal person, and is also more suitable for the physiological habits of the human body; in order to extend the service life of conveyor belt B506 and improve the force structure, rollers B505 are designed with high density and close distance on the upper layer and sparse and long distance on the lower layer; the multi-station full-inspection transmission mechanism 5 is the very end of this assembly line. This process has very little sand and dust, and the second layer can be designed to receive sand trays for auxiliary use. It is an open design and does not need to be closed.

[0043] In one of the embodiments, a material guide plate 308 is provided on one side of the frame A301 close to the material outlet of the sandblasting machine body 1 , and a material blocking plate 309 is provided on the other side of the frame A301 corresponding to the material guide plate 308 .

[0044] In one embodiment, a sand receiving tray 307 is provided inside the frame A 301 and is located below the conveyor belt A 306. The sand receiving tray 307 is provided with a steel sand storage box A 6. In order to facilitate the separation and cleaning of the steel sand powder, a sand receiving tray 307 is designed below the conveyor belt A 306.

[0045] In one embodiment, a sand receiving tray 406 is provided inside the frame B401 and is located below the damping spring 402. The sand receiving tray 406 is an inclined structure that gradually decreases from the lower end to the higher end of the vibrating screen 403. The sand receiving tray 406 is provided with a steel sand storage box B. In order to facilitate the collection of steel sand particles, the sand receiving tray 406 is designed below the vibrating screen 403.

[0046] In one embodiment, a plurality of operating stations 507 are evenly arranged on one side of the frame C501, and a slide plate 508 corresponding to the operating station 507 is provided on the other side of the frame C501; the discharge end of the multi-station full inspection conveying mechanism 5 is provided with a qualified product turnover box 7, and the slide plate 508 of the multi-station full inspection conveying mechanism 5 is provided with a defective product turnover box. The design of multiple operating stations 507 is not only conducive to the sparse arrangement of workpieces on the conveyor belt B506, but also conducive to the operator to perform flip inspection, which is helpful for intuitive inspection. After the operator's quality inspection, most of the qualified products are transported to the qualified product turnover box 7 at the discharge end of the multi-station full inspection conveying mechanism 5 through the conveyor belt B506, and a few defective products are picked out and flow into the defective product turnover box through the slide plate, which greatly reduces the labor intensity of the workers.
