Description

Technical Field

[0001] This utility model relates to the field of microgram weight controller technology, specifically to an integrated microgram weight control device for color masterbatch. Background Technology

[0002] In the plastics processing industry, the microgram weight controller is a control device used to control the feeding of plastic products such as plastic films, pipes, and cables. This is because the actual bulk density of raw materials like plastic granules changes constantly, resulting in uneven flow, and factors such as day-night temperature differences, power grid voltage fluctuations, and filter clogging can cause uneven thickness in the finished product. The controller is installed above the feed inlet and collects material input through a weighing module. Its built-in algorithm adjusts the main unit's speed to stabilize the output. By installing encoders, the main unit's speed and traction speed can be adjusted separately to strictly control the weight per meter of pipe, achieving a constant weight per meter. In existing technologies, color masterbatch plastic granules and corresponding functional material components are usually added during the molding process of plastic products. To ensure uniform color and stable performance of the molded plastic parts, the microgram weight controller is typically used to adjust and mix the proportions of these materials, ensuring uniform processing and producing stable products. The existing technology has the following problems:

[0003] Chinese patent document CN221249459U discloses a color masterbatch weight integrated control device, relating to the field of weight controller technology. It includes a weight controller body with a CNC panel on one side, a feeding frame above the body, a screening mechanism inside the feeding frame, and a clearing mechanism below the screening mechanism. The screening mechanism includes a mounting frame, a screen, and a supporting recess. The clearing mechanism includes a slider, a connecting block, and a clearing plate. This invention uses a motor to drive a lead screw to move the slider up and down, which in turn moves the connecting block on a limit rod up and down. The connecting block then moves the clearing plate up and down, scraping off the raw material adsorbed on the inner wall of the feeding frame. The spring force allows the clearing plate to adapt to the inner wall of the feeding frame during movement, always maintaining contact with it, thus facilitating clearing.

[0004] The aforementioned literature mainly utilizes sieves to screen impurities in masterbatch raw materials. Although the sieve is easy to disassemble and clean, it remains fixed during screening. When the masterbatch raw material is placed directly into the feed frame, it falls directly onto the sieve, making rapid screening difficult and resulting in poor screening efficiency. Furthermore, in the aforementioned literature, both the lead screw and the spring inside the concave block are exposed within the feed frame and come into direct contact with the masterbatch raw material. Over time, this can affect the transmission efficiency of the lead screw and clog the spring, preventing it from releasing its elastic force properly. Ultimately, this leads to an inability to reliably remove the masterbatch raw material adsorbed and accumulated at the feed frame outlet. Utility Model Content

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1 , Figure 2 As shown, this utility model provides an integrated control device for the gram weight of color masterbatch, including a gram weight controller body 1. The specific structure and operating principle of the gram weight controller body 1 are common knowledge in the field, so they will not be described in detail here. The top of the gram weight controller body 1 is provided with a feed inlet 2, and the top of the feed inlet 2 is provided with a discharge cylinder 3. The top of the discharge cylinder 3 is fixedly connected to a screening cylinder 4. The rear side of the inner wall of the screening cylinder 4 is provided with a drive groove 41. A servo motor 42 is fixedly installed on the rear side of the screening cylinder 4. The servo motor 42 is powered by an external power supply through a wire. The output shaft of the servo motor 42 passes through the inner cavity of the drive groove 41 and is fixedly installed with a cam 43. Telescopic rods 411 are fixedly installed on the left and right sides of the top of the inner wall of the drive groove 41. A lifting plate 412 is fixedly installed at the bottom of 411. A spring 413 is fixedly installed at the top center of the lifting plate 412. The top of the spring 413 is fixedly connected to the bottom of the inner wall of the drive groove 41. A drive groove 44 is opened on the front side of the inner wall of the screening cylinder 4. Two slide rods 441 are fixedly installed between the upper and lower sides of the inner wall of the drive groove 44. A slide plate 442 is slidably installed on the outer wall of the two slide rods 441. A spring 443 is fixedly installed at the top center of the slide plate 442. The top of the spring 443 is fixedly connected to the bottom of the inner wall of the drive groove 44. Telescopic rubber belts 45 are fixedly installed on the upper and lower sides of the lifting plate 412 and the slide plate 442. The telescopic rubber belts 45 are fixedly connected to the upper and lower sides of the inner wall of the drive groove 41 and the upper and lower sides of the inner wall of the drive groove 44, respectively.

[0024] When the color masterbatch material is poured from the top of the screening cylinder 4, it falls directly onto the screen 471 inside the screening ring plate 47. Simultaneously, the servo motor 42 drives the cam 43 in the drive groove 41 to rotate. The protrusion of the cam 43 presses against the lifting plate 412, causing it to move upwards. As the telescopic rod 411 shortens, the spring 413 is compressed. When the protrusion of the cam 43 moves away from the lifting plate 412, the lifting plate 412 quickly falls back due to the rebound of the spring 413, thus driving the plates fixed to the lifting plate 412 and the slide plate 44... 2. The top screening ring plate 47 vibrates up and down to improve the screening efficiency of the masterbatch material on the screen 471. At the same time, when the slide plate 442 moves up and down with the screening ring plate 47, it also slides up and down on the outer wall of the slide rod 441 and performs compression and rebound operations on the second spring 443 to ensure that the screening ring plate 47 can vibrate up and down stably. When the slide plate 442 and the lifting plate 412 move up and down, the telescopic rubber belt 45 can block the inner cavity of the second drive groove 44 and the first drive groove 41, thereby effectively preventing the masterbatch material from entering its inner cavity and affecting normal vibration.

[0025] like Figure 3 As shown, the opposite ends of the lifting plate 412 and the sliding plate 442 both extend into the inner cavity of the screening cylinder 4, and each is fixedly equipped with a plate 46 at its top. Both plates 46 have through-hole locking threads 461. A screening ring plate 47 is engaged within the inner cavity of the screening cylinder 4. The top of the screening ring plate 47 is inclined inwards to prevent the accumulation and residue of color masterbatch material at its top. A screen 471 is fixedly installed below the inner ring of the screening ring plate 47. The bottom of the screening ring plate 47 has locking grooves 472 on both the front and rear sides. The two locking grooves 472 engage with the two plates 46 respectively. The screen has threaded holes 473 that extend to the inner ring of the screen ring plate 47. The two threaded holes 473 are aligned with the two locking threaded holes 461. The inner ring of each of the two threaded holes 473 is threaded with a locking thread rod 477. A knob 476 is fixedly installed at the end of each locking thread rod 477 away from the threaded hole 473. A retaining ring 475 is movably installed on the outer wall of each of the two knobs 476. A connecting band 474 is fixedly installed on the outer wall of each of the two retaining rings 475. The other ends of the two connecting bands 474 are fixedly connected to the front and rear sides of the inner ring of the screen ring plate 47.

[0026] When the screening is finished and the filter material on the screen 471 needs to be cleaned, simply rotate the two knobs 476 on the inner ring of the screening ring plate 47. This will rotate the locking threaded rod 477 until it is completely disengaged from the mating threaded hole 473 and the locking threaded hole 461 in the insert plate 46. This releases the fixation of the screening ring plate 47, and using the rotatable fixing ring 475 on the outer wall of the knob 476 and the connecting belt 474, the entire screening ring plate 471 can be lifted upwards directly with the help of the locking threaded rod 477. 7. For easy disassembly and installation, align the screening ring plate 47 with the inner cavity of the screening cylinder 4 and insert it until the insert plate 46 is inserted into the snap-fit ​​groove 472, so that the locking thread hole 461 and the mating thread hole 473 are aligned front and back. Then, align the locking thread rod 477 with the mating thread hole 473 and rotate the knob 476 to tighten and fix the screening ring plate 47, so that the screening ring plate 47 is fixed with the lifting plate 412 and the slide plate 442, and the newly added color masterbatch raw material can be vibrated and screened again.

[0027] like Figure 4 , Figure 5 As shown, an extension rod 31 is fixedly installed on the upper rear side of the inner wall of the feeding cylinder 3. A servo motor 32 is fixedly installed at the front end of the extension rod 31. The servo motor 32 is powered by an external power supply through a wire. A conical top cover 33 is fixedly installed on the top of the servo motor 32. The bottom diameter of the conical top cover 33 is larger than the top diameter of the servo motor 32. A feeding funnel 34 is fixedly connected to the bottom of the feeding cylinder 3. The bottom of the feeding funnel 34 is fixedly connected to the top of the feed inlet 2. L-shaped hanging rods 321 are fixedly installed on both sides of the output shaft of the servo motor 32. The vertical sides of the two L-shaped hanging rods 321 overlap with the inner wall of the feeding cylinder 3. Inclined scrapers 322 are fixedly installed at the bottom of the vertical sides of the two L-shaped hanging rods 321. The opposite sides of the two inclined scrapers 322 overlap with the inner ring of the feeding funnel 34.

[0028] After screening, the masterbatch material will fall directly into the inner cavity of the feeding cylinder 3. The conical top cover 33 can prevent the masterbatch material from accumulating on the top of the servo motor 32. At the same time, starting the servo motor 32 can drive the two L-shaped lifting rods 321 and the two inclined scrapers 322 to rotate clockwise, scraping off the masterbatch material attached to the inner ring of the feeding cylinder 3 and the inner ring of the feeding funnel 34. The inclined nature of the inclined scraper 322 can make the scraped masterbatch material move closer to the bottom of the feeding cylinder 3 until it enters the inner cavity of the micrometer weight controller body 1 through the feed inlet 2.

[0029] The working principle of this color masterbatch weight integrated control device will be explained in detail below.

[0030] like Figure 1-5As shown, when the masterbatch material is poured from the top of the screening cylinder 4, it falls directly onto the screen 471 inside the screening ring plate 47. Simultaneously, the servo motor 42 drives the cam 43 in the drive groove 41 to rotate. The protrusion of the cam 43 presses against the lifting plate 412, causing it to move upwards. As the telescopic rod 411 shortens, the spring 413 is compressed. When the protrusion of the cam 43 moves away from the lifting plate 412, the lifting plate 412 quickly falls back due to the rebound of the spring 413. This causes the screening ring plate 47, fixed to the top of the lifting plate 412 and the slide plate 442, to vibrate up and down, improving the coloring effect on the screen 471. The screening efficiency of the raw material is improved. Simultaneously, as the sliding plate 442 moves up and down following the screening ring plate 47, it also slides up and down on the outer wall of the sliding rod 441, compressing and rebounding the second spring 443. This ensures that the screening ring plate 47 can vibrate stably up and down. Furthermore, when the sliding plate 442 and the lifting plate 412 move up and down, the telescopic rubber belt 45 can shield the inner cavity of the second drive groove 44 and the first drive groove 41, effectively preventing the raw material from entering the inner cavity and affecting normal vibration. When the screening is finished and the filter material on the screen 471 needs to be cleaned, simply rotate the two knobs 476 on the inner ring of the screening ring plate 47 to drive the locking threaded rod 477. Rotate until it is completely disengaged from the mating threaded hole 473 and the locking threaded hole 461 of the insert plate 46, thereby releasing the fixation of the screening ring plate 47. Using the rotatable fixing ring 475 on the outer wall of the knob 476 and the connecting strap 474, the entire screening ring plate 47 can be lifted upwards directly with the locking threaded rod 477 for easy disassembly. During installation, align the screening ring plate 47 with the inner cavity of the screening cylinder 4 and lower it into place until the insert plate 46 engages in the locking groove 472, aligning the locking threaded hole 461 with the mating threaded hole 473. Then, align the locking threaded rod 477 with the mating threaded hole 473 and rotate the knob 476 to tighten and fix the screening ring plate 47. The screening ring plate 47 is fixed with the lifting plate 412 and the sliding plate 442, so that the newly added color masterbatch raw material can be vibrated and screened again. The screened color masterbatch raw material will fall directly into the inner cavity of the feeding cylinder 3. The conical top cover 33 can prevent the color masterbatch raw material from accumulating on the top of the servo motor 32. At the same time, the servo motor 32 can drive the two L-shaped hanging rods 321 and the two inclined scrapers 322 to rotate clockwise, scraping off the color masterbatch raw material attached to the inner ring of the feeding cylinder 3 and the inner ring of the feeding funnel 34. The inclined nature of the inclined scraper 322 can make the scraped color masterbatch raw material approach the bottom of the feeding cylinder 3 until it enters the inner cavity of the micrometer weight controller body 1 through the feed inlet 2.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
