Description

Technical Field

[0001] The utility model relates to the technical field of parts sandblasting equipment, in particular to a sandblasting parts spreading and full inspection production line. Background Art

[0002] Sandblasting is a common surface treatment technology, also known as sand grinding, sandblasting cleaning, etc. Sandblasting is to spray sand grains or other granular materials at high speed and impact them on the surface of the object to be treated, so as to achieve the purposes of cleaning, removing dirt, and improving surface quality. Its principle is to use the impact force of the high-speed sprayed sand grains to remove dirt, oxide layer, coating and other substances on the surface of the object to be treated, so that the surface is restored to be smooth and has an appropriate roughness, providing a good foundation for subsequent processes such as painting, spraying, electroplating, etc.

[0003] Sandblasting can be applied to the surface treatment of various materials, such as metals, glass, ceramics, plastics, etc. In the industrial field, sandblasting is often used for the surface treatment of metal products, such as automotive parts, mechanical equipment, pipelines, etc. In the construction field, sandblasting can be used to clean the surfaces of walls, stones, concrete, etc. to remove dirt and aging layers, so as to restore their original beauty and texture. In addition, sandblasting can also be used in the fields of art production, mold repair, etc.

[0004] In the mechanical forging industry or casting industry, the parts are relatively precise, and small parts with high precision or appearance requirements must be sandblasted to ensure product quality. After the parts are processed by the sandblasting machine, it is necessary to pick out the unqualified products. The existing operation is as follows: First, a large number of workers manually load the parts into the sandblasting machine. After the sandblasting process, they are then loaded into the turnover iron box through the sandblasting outlet and dumped on the ground iron plate or large workbench by manual or forklift. At this time, a large pile of parts are stacked on top of each other. The operator needs to manually spread them out and carefully pick out the defective or quality-defective substandard or defective products. The qualified products normally flow into the next process, and the unqualified products are collected for repair or scrapping. This traditional operation method requires repeated dumping many times, resulting in a large labor intensity for workers, wasting a lot of labor, and moreover, the sandblasted parts are accompanied by a large amount of steel sand powder, which is prone to dust and affects the health of workers.

A conveyor belt B506 is provided on the driving roller B502, the driven roller B503, and the supporting rollers B505.

[0031] The working principle of the present utility model;

[0032] This production line mainly consists of a sandblasting machine main body 1, a lifting and tilting feeding mechanism 2, a discharging conveyor mechanism 3, a vibrating screening mechanism 4, and a multi-station full-inspection conveyor mechanism 5. The overall adopts a segmented continuous design, and each segment specifically adopts an inclined forward structure. Among them, the lifting and tilting feeding mechanism 2 is used for feeding at the front end of the sandblasting machine main body 1. Mechanical parts enter the sandblasting machine main body 1 through the lifting and tilting feeding mechanism 2. After being processed by the sandblasting process, they enter the discharging conveyor mechanism 3. The discharging conveyor mechanism 3 transports the mechanical parts to the vibrating screening mechanism 4. After being spread and separated by the vibrating screening mechanism 4, they are transported to the multi-station full-inspection conveyor mechanism 5. Finally, the staff conducts quality inspection, turnover and other operations on the mechanical parts through the multi-station full-inspection conveyor 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 main body 1. The size range of the inlet is matched by the lifting and tilting height of the lifting and tilting feeding mechanism 2. For those with a height lower than 1.3m, a first-level lifting and tilting is advisable; for those exceeding 1.3m, a two-level lifting plus tilting is advisable. On the premise that the outlet size (normally about 800mm) is fixed, considering the smoothness of the production line and the drop degree of the connection of each part (when the radius of curvature R100 of the conveyor belt roller is relatively large, the drop should not be less than 100mm), if each section normally adopts a planar design plus a staged drop, the height of the full inspection conveyor belt at the end of the production line will be too low (lower than 600mm), resulting in too low an operating surface for the operator whether standing or sitting, which does not conform to the habits of visual inspection and human physiological functions. To overcome this drawback, the height of this production line is designed in a jumping-forward mode, that is: the discharge conveyor mechanism 3, the vibrating screening mechanism 4, and the multi-station full inspection conveyor mechanism 5 all adopt an inclined design, that is: the conveyor belt A306 of the discharge conveyor mechanism 3 goes from low to high; the vibrating screen 403 of the vibrating screening mechanism 4 goes from high to low; the conveyor belt B506 of the multi-station full inspection conveyor mechanism 5 goes from low to high; this inclined design realizes the perfect connection in space and the high fit in function of each section.

[0034] See Figure 2 , under normal conditions, the inner material box 203 of the lifting and tilting feeding mechanism 2 is located below the outer tilting frame 202; at the same time, the tilting oil cylinder 206 is in a contracted state, and the lifting oil cylinder 207 is in an extended state. The operator transports the materials into the inner material box 203 through a transportation tool, and operates the lifting oil cylinder 207 with a remote control. The oil cylinder contracts to lift the inner material box 203 into the outer tilting frame 202, that is, to the first-level height; when the predetermined position is reached, the inner material box 203 will touch the configured limit switch, and the limit switch generates a signal and notifies the tilting oil cylinder 206 to act. The tilting oil cylinder 206 starts to extend to drive 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. The parts in the inner material box 203 will then be dumped and flow smoothly into the hopper of the sandblasting machine main body 1.

[0035] The lifting and tilting feeding mechanism 2 can adapt to multiple models of sandblasting machine main bodies 1, with high adaptability. Whether to use a two-level lifting structure can be appropriately selected according to the inlet height of the sandblasting machine main body 1. If the height is within the range of lower than 1.3m, the inner material box 203 and the lifting oil cylinder 207 can be omitted, and the outer tilting frame 202 can be directly placed on the ground (with a 10mm iron plate sealed at the bottom), and the operator can push the material turnover box in manually.

[0036] The inner material box 203 has dimensions of 1150 in length * 800 in width * 1000 in height, and has a high adaptability to accommodate the existing material turnover boxes. The conventional turnover weight of a conventional mechanical hydraulic trolley and a forklift is 500 kg - 1000 kg, and the size specifications are usually length ≤ 1000 mm, width ≤ 700 mm, and height ≤ 700 mm. If the size is too large and the weight is too heavy, it is not easy to take into account the feed inlet of the sandblasting machine main body 1 when directly using a conventional mechanical hydraulic trolley and a forklift.

[0037] Since the inner material box 203 is heavy and tall after loading, for safety, the operation is controlled by a remote controller at a distance. The traditional relay button control is abandoned, and a six-way wireless receiving controller is adopted. The power supply is Dc - 12 - 36V, and the receiving sensitivity is higher than -105 dbm; and the cylinder load is 500 - 1000 kg. To ensure high safety and take into account work efficiency, the cylinder adopts the D80 - B type, and the oil pump power is greater than or equal to 5.5 kw; at the same time, the outer tilting frame 202 and the inner material box 203 have a large tilting angle, ≥ 60 degrees, the pouring is complete, and the work efficiency is high.

[0038] To improve the strength and stiffness of the outer tilting frame 202 and the inner material box 203 and reduce their own weight, the outer tilting frame 202 mainly uses 10 - channel steel as the skeleton and is covered with 6 - mm iron plate. The inner material box 203 is mainly welded into a single - sided open - basket type with 10 - mm iron plate. The outer tilting frame 202 and the inner material box 203 are slidably connected by the guide rail 208, so that the contact is smooth without jamming, and the structure has higher strength, more reasonable force, and more convenient maintenance, thus being more durable.

[0039] There is one tilting cylinder 206 and one lifting cylinder 207 on each side. Each hydraulic oil circuit inlet and outlet oil pipe is divided into two paths, and it is easy to produce imbalance in the load - bearing, resulting in asynchronous phenomena of the two cylinders in a set of actions. Specifically, the left and right forces of a set of cylinders are uneven, and the hydraulic cylinder trembles weakly and shakes; to solve this problem, a hydraulic synchronous motor is added to the hydraulic oil circuit. Model selection: SHxy - 2R - 4.2S. Through the application of hydraulic synchronous technology, the on - site problems of the equipment are well solved, and the operation effect is very stable and the effect is ideal.

[0040] See Figure 3 and Figure 4, for the convenience of discharging and receiving materials of the sandblasting machine main body 1, the discharging conveyor mechanism 3 adopts a side-receiving design. As much as possible, a large-width receiving surface with a width of ≥600 mm and a length of 3 m is used to match the conventional sandblasting machine main body 1. Among them, the slope of the conveyor belt A306 is 1:15, and the conveyor belt A306 is designed to rotate forward and backward to prevent blockage during discharging. The matching driving motor A304 is 1.5 kw, the reduction ratio i = 29, and the linear speed is 30 m / min. To reduce flying dust and improve the on-site environment, the conveyor belt A306 adopts a closed design: that is, one-sided guard plates are fixed, and the easy-to-operate side has detachable guard plates, which are convenient for cleaning leaked sand and maintenance; at the same time, to extend the service life of the conveyor belt A306, reduce the impact of falling parts on the belt and rollers, and improve the force structure, the rollers A305 adopt a design with a high density in the upper layer and a close distance, and a sparse and long-distance layout in the lower layer. Combining with the actual spatial structure layout, the driving motor A304 is arranged above the conveyor belt A306 to facilitate the tension 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 wires (fully inspected conveyor belt B500*t10). Based on this, the curvature radius of the driving roller A302 is too small and it is not easy for the conveyor belt to bend. Using D200 can also take into account the space installation of the roller A305.

[0041] See Figure 5 and Figure 6 , combining with the actual production situation, the vibrating screening mechanism 4 adopts a dustpan type, and its vibrating screen 403 adopts a polarized structure, that is, the vibrating screen 403 is an inclined structure that gradually decreases along the material discharging direction; the model of the vibrating motor 405 is selected as ZFB-9-0.75 kw, the exciting force is 15 KN, the vibration frequency is 3000 times / min, and the vibrating motor 405 is installed at the high end of the vibrating screen 403. This design not only facilitates maintenance but also helps to generate a reciprocating force for forward circulating feeding, effectively improving the vibrating screening effect; a closed and detachable guard plate is provided around the vibrating screen 403, which is both dust-proof and conducive to maintenance and disassembly. The slope of the vibrating screen 403 is 1:10 and leak holes are designed at the bottom, which is not only conducive to vibrating discharging but also easy to completely separate the steel sand powder particles. It should be noted that the damping spring 402 is designed with a limit dust-proof sleeve; due to the high vibration frequency of the vibrating motor 405, the vibrating screening mechanism 4 is prone to displacement, and the frame B401 of the vibrating screening mechanism 4 can be fixed by driving expansion bolts on the ground.

[0042] See Figure 7, in order to match the feeding speed of the vibrating screen 403 and the full inspection speed of the operators, the multi-station full inspection conveyor mechanism 5 is controlled by the console 509. 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 length of the conveyor belt B506 is 6m, and the conveyor belt B506 is designed to rotate forward and backward to prevent missing inspections due to excessive speed at startup or in the initial stage, so that it can be returned for inspection in real time according to the site. Since the conveyor belt B506 is relatively long and requires a large amount of power, a 4kw cycloidal pinwheel drive motor B504 is used, which is compactly arranged at the bottom layer, with the model Xwd-4-i17; the height of the conveyor belt B506 is 750-950mm, which is a suitable height that is easy to take into account whether standing or sitting according to the normal human height, and is more suitable for human physiological habits; in order to extend the service life of the conveyor belt B506 and improve the stress structure, the idler B505 adopts a design with a high density and close distance on the upper layer and a sparse and long distance arrangement on the lower layer; as the end of this production line, there is very little dust in this process, and a sand receiving tray can be designed on the second layer for auxiliary use, which is an open design and does not require enclosure.

[0043] In one embodiment, a guide plate 308 is provided on one side of the frame A301 close to the discharge port of the sandblasting machine main body 1, and a baffle plate 309 is provided on the other side of the frame A301 corresponding to the guide plate 308.

[0044] In one embodiment, a sand leakage receiving tray 307 is provided inside the frame A 301 below the conveyor belt A306. The sand leakage receiving tray 307 is equipped with a steel sand storage box A6. In order to facilitate the separation and cleaning of the steel sand powder attached, the sand leakage receiving tray 307 is designed below the conveyor belt A306.

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

[0046] In one of the embodiments, a number of operating stations 507 are evenly arranged on one side of the frame C501, and a slide plate 508 corresponding to the operating stations 507 is provided on the other side of the frame C501; a qualified product turnover box 7 is provided at the discharge end of the multi-station full inspection conveyor mechanism 5, and a non-conforming product turnover box is provided for the slide plate 508 of the multi-station full inspection conveyor mechanism 5.
