Description

Technical Field

[0001] This utility model relates to the field of metal separator technology, specifically a PLC-based metal separator control system. Background Technology

[0002] A free-fall metal separator is a device that separates metals from non-metals through free-fall motion combined with detection technology. It is often used in injection molding workshops to remove metal impurities mixed in plastic raw materials or to recycle resources. Taking the free-fall PLC-based metal separator control system as an example.

[0003] The partial free-fall type PLC-based metal separator control system is inconvenient for controlling the discharge flow rate of the mixture of plastic granules and metal impurities, and it is also inconvenient for performing multiple controlled screening processes on the mixture of plastic granules and metal impurities. Therefore, a PLC-based metal separator control system is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a PLC-based metal separator control system to solve the problem that some drop-type PLC-based metal separator control systems are inconvenient to control the discharge flow rate of the mixture of plastic granules and metal impurities, and are inconvenient to perform multiple controlled screening processes on the mixture of plastic granules and metal impurities.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A PLC-based metal separator control system includes a free-fall metal separator body, a feeding assembly, and an adjustment and control assembly. The feeding assembly is located on top of the free-fall metal separator body, and the adjustment and control assembly is located inside the feeding assembly. The adjustment and control assembly includes a disc plate, connecting plates, a stepper motor, a shaft, a screw, a limit rod, a lower blocking block, an upper blocking block, a cylindrical ring, a platform, an inner ring plate, an outer ring plate, a silicone pad, and a guide shell. Two connecting plates are symmetrically and fixedly arranged on the left and right ends of the disc plate. A stepper motor is fixedly mounted on the top of the disc plate. A shaft is fixedly mounted on the end of the stepper motor spindle. A screw is fixedly mounted on the bottom end of the shaft. A limit rod and a cylindrical ring are fixedly mounted on the bottom end of the disc plate. A lower blocking block is fixedly mounted below the limit rod. An upper blocking block is fixedly mounted on the outer side of the middle part of the limit rod. A platform is mounted on the outer side of the screw and the outer side of the limit rod. An inner ring plate and an outer ring plate are fixedly mounted inside the upper part of the platform. A silicone pad is fixedly mounted on the outer side of the platform. A guide shell is fixedly mounted on the bottom end of the platform.

[0007] Preferably, the feeding assembly includes a feeding pipe, a discharging hopper, and ear plates. The discharging hopper is fixedly installed at the top of the feeding pipe, and two ear plates are symmetrically and fixedly installed on the inner walls of the left and right ends of the discharging hopper.

[0008] Preferably, the outer side of the screw is threadedly assembled with the inner side of the platform, and the inner side of the platform is slidably disposed with the outer side of the limiting rod.

[0009] Preferably, the bottom end of the connecting plate is placed in close contact with the top end of the ear plate, and the inside of the ear plate and the inside of the connecting plate are threaded together by studs.

[0010] Preferably, the inclined end face inside the hopper and the inclined end face outside the silicone pad are both set at 45 degrees to the horizontal plane.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the stepper motor starts rotating forward, causing the inside of the platform to slide vertically downward along the outside of the limiting rod, adding the mixture of plastic granules and metal impurities to be separated into the hopper. The stepper motor starts rotating in reverse, causing the inside of the platform to slide vertically upward along the outside of the limiting rod, thus controlling the size of the opening area between the hopper, the inner wall of the feed pipe, the platform, and the guide shell. The automatic rejection device inside the main body of the drop-type metal separator can discharge and reject metal impurities and a small amount of plastic granules in the nearby area. After the initially screened metal impurities and the small amount of plastic granules in the nearby area are gathered, they are put back into the hopper, and the size of the opening area between the hopper, the inner wall of the feed pipe, the platform, and the guide shell is reduced, allowing for multiple controlled screening processes. Through the above settings, the main body of the system device can easily control the discharge flow rate of the mixture of plastic granules and metal impurities, facilitating multiple controlled screening processes of the mixture.

[0024] Please see Figure 1-7 This utility model provides a technical solution:

[0025] A PLC-based metal separator control system includes a free-fall metal separator body 1, a feeding assembly 2, and an adjustment and control assembly 3. The feeding assembly 2 is located on the top of the free-fall metal separator body 1, and the adjustment and control assembly 3 is located inside the feeding assembly 2. The adjustment and control assembly 3 includes a disc plate 301, a connecting plate 302, a stepper motor 303, a shaft 304, a screw 305, a limit rod 306, a lower blocking block 307, an upper blocking block 308, a cylindrical ring 309, a platform 310, an inner ring plate 311, an outer ring plate 312, a silicone pad 313, and a guide shell 314. Two connecting plates 302 are symmetrically and fixedly arranged on the left and right ends of the disc plate 301. A stepper motor 303 is fixedly installed at the top of the plate 301. A shaft 304 is fixedly installed at the end of the main shaft of the stepper motor 303. A screw 305 is fixedly installed at the bottom of the shaft 304. A limit rod 306 and a cylindrical ring 309 are fixedly installed at the bottom of the plate 301. A lower blocking block 307 is fixedly installed below the limit rod 306. An upper blocking block 308 is fixedly installed on the outer side of the middle part of the limit rod 306. A platform 310 is installed on the outer side of the screw 305 and the outer side of the limit rod 306. An inner ring plate 311 and an outer ring plate 312 are fixedly installed inside the upper part of the platform 310. A silicone pad 313 is fixedly installed on the outer side of the platform 310. A guide shell 314 is fixedly installed at the bottom of the platform 310.

[0026] The feeding assembly 2 includes a feeding pipe 21, a discharge hopper 22, and ear plates 23. The discharge hopper 22 is fixedly installed at the top of the feeding pipe 21. Two ear plates 23 are symmetrically and fixedly installed on the inner walls of the left and right ends of the discharge hopper 22. Through the above arrangement, an integrated feeding assembly 2 is formed.

[0027] The screw 305 is threaded to rotate on the outside of the platform 310, and the platform 310 is slidably connected to the outside of the limiting rod 306. Through the above arrangement, the screw 305 and the limiting rod 306 together limit the sliding of the platform 310.

[0028] The bottom end of the connecting plate 302 is placed in close contact with the top end of the ear plate 23. The inside of the ear plate 23 and the inside of the connecting plate 302 are threaded together by studs. The above arrangement facilitates the installation of the feeding component 2 and the adjustment and control component 3.

[0029] The inclined end face inside the hopper 22 and the inclined end face outside the silicone pad 313 are both set at 45 degrees to the horizontal plane. This setting facilitates the silicone pad 313 to fit and contact the inner wall of the hopper 22, allowing the addition of a mixture of plastic granules and metal impurities to be separated into the hopper 22.

[0030] Workflow: This utility model provides a PLC-based metal separator control system. The main body of the system device facilitates the control of the discharge flow rate of the mixture of plastic granules and metal impurities, and facilitates multiple controlled screening processes of the mixture of plastic granules and metal impurities.

[0031] The front end of the free-fall metal separator body 1 is equipped with a PLC controller device. The PLC controller device performs power supply control processing on the stepper motor 303 and the internal electrical components of the free-fall metal separator body 1. The free-fall metal separator body 1 is an existing technology device, which will not be described in detail in this article.

[0032] First, the adjustment and control component 3 is installed inside the feeding component 2. The ear plate 23 and connecting plate 302 are threaded together using studs. The stepper motor 303 starts rotating forward, driving the shaft 304 and screw 305 to rotate. The outer side of the screw 305 rotates threadedly inside the platform 310. The limiting rod 306 limits the movement of the platform 310, causing it to slide vertically downwards along the outer side of the limiting rod 306 until the silicone pad 313 contacts the inner wall of the discharge hopper 22. A mixture of plastic granules and metal impurities to be separated is added into the discharge hopper 22. The stepper motor 303 then starts rotating in reverse, driving the shaft 304 and screw 305 to rotate. The outer side of the screw 305 rotates threadedly inside the platform 310. The limiting rod 306 then limits the movement of the platform 310. The limiting function of plate 310 allows the inside of the plate 310 to slide vertically upward along the outside of the limiting rod 306, thereby controlling the size of the opening area between the inner wall of the hopper 22 and the feed pipe 21 and the plate 310 and the guide shell 314. This allows for adjustment of the feeding speed of the input mixture. The automatic rejection device inside the main body 1 of the drop-type metal separator can discharge and reject metal impurities and a small amount of plastic particles in the nearby area. After the metal impurities and the small amount of plastic particles in the nearby area are gathered together, they are put back into the hopper 22, and the size of the opening area between the inner wall of the hopper 22 and the feed pipe 21 and the plate 310 and the guide shell 314 is reduced, which facilitates multiple controlled screening processes for the mixture of plastic particles and metal impurities.

[0033] Although embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined by the appended claims and their equivalents.
