Abstract
Description
Technical Field
[0001] This utility model relates to the field of material feeding technology, and in particular to a new type of raw material feeding device for optically variable functional masterbatch. Background Technology
[0002] The full name of color masterbatch is masterbatch, which is a new type of special coloring agent for polymer materials, also known as pigment preparation. The processing of masterbatch mainly includes weighing, stirring, extrusion, strip drawing, pelletizing and packaging. During processing, a feeding device is required to add the masterbatch into the processing machinery.
[0003] The patent with patent publication number CN217478562U discloses a carbon black masterbatch feeding device. The patent proposes that by using the cooperation of the slider and the limiting block on the transmission rod, the telescopic rod can move back and forth, thereby knocking off the material adhering inside the material bag. However, the patent still has some shortcomings in actual use. Since the capacity of each processing machine is different and the processing machine is usually a closed structure, it is not convenient for the staff to judge the amount of material to be fed. Utility Model Content
[0004] To overcome the shortcomings of inconsistent capacity of each processing machine and the fact that processing machines are usually enclosed structures, making it inconvenient for workers to judge the amount of material to be fed, this utility model provides a new type of raw material feeding device for optically variable functional masterbatch. This feeding device achieves quantitative feeding by setting baffles and elastic elements.
[0005] A novel raw material feeding device for photochromic masterbatch includes a feeding cylinder, a support frame, a screw, and a nut. The feeding cylinder is fixedly connected to the middle of the support frame, and the screw is rotatably mounted at the front of the support frame. The screw is threaded with a nut. The device also includes a baffle and elastic elements. The bottom of the feeding cylinder is symmetrically and rotatably mounted with baffles. Two elastic elements are sleeved on the baffles, and the two ends of the elastic elements are connected to the baffles and the feeding cylinder, respectively.
[0006] Furthermore, it also includes a limiting cylinder, a guide cover, a magnet, and a collection frame. The limiting cylinder is fixed to the top of the feeding cylinder, and guide covers are fixed to both the left and right sides of the limiting cylinder. A magnet is embedded in the guide cover, and a collection frame is slidably installed at the bottom of the guide cover.
[0007] Furthermore, it also includes a support rod, a pulley, a pull rope, and a top block. The support rod is fixedly connected inside the limiting cylinder. A pulley is rotatably installed in the middle of the support rod. A pull rope is wound around the pulley. A top block is fixedly connected to the bottom end of the pull rope. The top block is in contact with the baffle.
[0008] Furthermore, it also includes a protective frame, which is fixed to the support rod.
[0009] Furthermore, it also includes a scraper, which is slidably installed inside the guide cover and contacts the magnet.
[0010] Furthermore, it also includes a support plate, which is slidably installed at the bottom of the feed cylinder, and the support plate locks the baffle.
[0011] Based on the above description of the structure of this utility model, the design starting point, concept, and advantages of this utility model are as follows:
[0012] 1. By pouring the masterbatch into the feeding cylinder, the masterbatch falls onto the baffle. When the masterbatch reaches a certain amount, it squeezes the baffle to rotate, thus allowing a certain amount of masterbatch to fall into the feeding port of the processing machine, thereby achieving the purpose of quantitative feeding.
[0013] 2. Iron filings contained in the masterbatch are attracted away by magnets and guide covers. The iron filings are attracted to the magnets, thereby improving the purity of the masterbatch.
[0014] 3. By inserting a quantitative weight into one end of the pull rope and locking the top block into the baffle, if the weight of the raw material on the baffle is greater than the weight, the baffle rotates and squeezes the top block to move downward, causing the pull rope to move downward and the pulley to rotate. Thus, the quantitative value can be controlled according to the weight, thereby meeting different feeding requirements. Attached Figure Description

Detailed Implementation
[0022] The present invention will now be described in detail with reference to the accompanying drawings.
[0023] Example 1
[0024] A novel raw material feeding device for optically variable functional masterbatch, see reference. Figures 1-5 As shown, it includes a feeding cylinder 1, a support frame 2, a screw 3, a nut 4, and a support plate 16. The feeding cylinder 1 is welded to the middle of the support frame 2. The screw 3 is rotatably mounted at the front of the support frame 2. The nut 4 is threaded onto the screw 3. The support plate 16 is slidably mounted at the bottom of the feeding cylinder 1. The support plate 16 holds the baffle 5 and prevents the baffle 5 from rotating. It also includes the baffle 5 and elastic elements 6. The baffle 5 is symmetrically rotatably mounted at the bottom of the feeding cylinder 1. Two elastic elements 6 are fitted on the baffle 5. The two ends of the elastic elements 6 are connected to the baffle 5 and the feeding cylinder 1, respectively.
[0025] When using this device, the operator removes the support plate 16 and places the device on the feeding port of the processing machine. The operator then rotates the screw 3 to engage the support frame 2, and then rotates the nut 4 to move it inward, thereby tightening the support frame 2 and fixing it on the feeding port of the processing machine. After fixing, the operator pours the masterbatch into the feeding cylinder 1, where it falls onto the baffle 5. When the masterbatch reaches a certain amount, it compresses the baffle 5 to rotate, and the operator stops feeding. The elastic element 6 deforms accordingly, allowing a certain amount of masterbatch to fall into the feeding port of the processing machine, thus achieving the purpose of quantitative feeding. After feeding, the elastic element 6 drives the baffle 5 to reverse back to its original position, and then the operator locks the support plate 16 back into its original position before proceeding with the subsequent masterbatch processing operation.
[0026] Example 2
[0027] Based on Example 1, see [link to Example 1] Figure 1 and Figure 4 As shown, it also includes a limiting cylinder 7, a guide cover 8, a magnet 9, a collection frame 10, and a scraper 15. The limiting cylinder 7 is welded to the top of the feeding cylinder 1. The guide cover 8 is fixed to both the left and right sides of the limiting cylinder 7. The magnet 9 is embedded in the guide cover 8. The collection frame 10 is slidably installed at the bottom of the guide cover 8. The scraper 15 is slidably installed in the guide cover 8. The scraper 15 contacts the magnet 9 and can scrape off the iron filings on the magnet 9.
[0028] When the masterbatch is poured into the feeding cylinder 1, the magnet 9 attracts the iron filings contained in the masterbatch through the guide cover 8. The iron filings are attracted to the magnet 9, thereby improving the purity of the masterbatch. After the feeding is completed, the worker pushes the scraper 15 downward, so that the scraper 15 scrapes the iron filings on the magnet 9 into the collection frame 10. Then the worker pulls out the collection frame 10 to clean up the iron filings. After cleaning, the worker puts the collection frame 10 back in its original position.
[0029] See Figure 5 and Figure 6 As shown, it also includes a support rod 11, a pulley 12, a pull rope 1201, a top block 13, and a protective frame 14. The support rod 11 is installed inside the limiting cylinder 7 by welding. The pulley 12 is rotatably installed in the middle of the support rod 11. The pull rope 1201 is wound around the pulley 12. The bottom end of the pull rope 1201 is fixed to the top block 13. The top block 13 is in contact with the baffle 5. The protective frame 14 is fixed to the support rod 11 to protect the weight.
[0030] Before feeding, the worker inserts a quantitative weight into one end of the pull rope 1201, and the top block 13 locks the baffle 5. If the weight of the raw material on the baffle 5 is greater than the weight, the baffle 5 rotates and presses the top block 13 downward. The downward movement of the baffle 5 drives the pull rope 1201 downward, which in turn drives the pulley 12 to rotate. This allows the quantitative value to be controlled according to the weight, thus meeting different feeding requirements. After feeding is completed, the weight pulls the pull rope 1201 downward, causing the pulley 12 to reverse and drive the top block 13 upward. The upward movement of the top block 13 causes the baffle 5 to reverse back to its original position. Repeating the above operation allows for further adjustment of the quantitative feeding amount.

The scope of the following claims should be given the broadest interpretation in order to cover all variations and equivalent structures and functions.
