Technical Field
[0001] This utility model relates to the field of plastic particle screening, specifically a multi-layer screening machine for plastic particle processing. Background Technology
[0002] The working principle of a multi-layer screening machine is to use the vibration force generated by the vibrator to screen the material on multiple layers of screens. When the vibrator starts working, upward and downward vibration forces are generated inside the screen box. These forces will throw the material onto the screen. Materials of different sizes will be screened step by step on different layers of screens. Larger particles are screened out, while smaller particles pass through the screen to the next layer for further screening, ultimately achieving the desired grading effect.
[0003] Multi-layer screening machines mainly consist of a screen box, vibrator, liner, and screen mesh. The screen box is an integral structure welded from steel plates, with multiple layers of screen mesh inside. Each layer of screen mesh has different aperture and mesh size to meet the screening needs of materials with different particle sizes. During use, the equipment body will vibrate. Moreover, multi-layer screening machines have multiple discharge ports, making it impossible to use large-diameter containers for receiving materials. Nowadays, most materials are received using woven bags, which are tied to the discharge port with ropes. When the ropes are not tied tightly, the bags are prone to falling off. Utility Model Content
[0004] To overcome the shortcomings of existing technology, most materials are currently collected using woven bags, which are tied to the discharge port with ropes. When the ropes are not tied tightly, the bags are prone to falling off. This utility model proposes a multi-layer screening machine for processing plastic granules.

[0008] Preferably, a knob is fixedly connected to the surface of the screw, a protective pad is fixedly connected to the top of the movable block, the inner cavity of the protective pad is movably connected to the surface of the screw, the protective pad is made of rubber, and the top of the protective pad is in close contact with the bottom of the fixing ring.
[0009] Preferably, a limiting block is fixedly connected to the bottom of the screw, and the top of the limiting block is in contact with the bottom of the movable block.
[0010] Preferably, the top of the movable ring is fixedly connected to a bottom connecting block, and there are two bottom connecting blocks.

[0013] The advantages of this utility model are:
[0014] This invention first involves evenly placing the opening of the woven bag on top of the fixing ring, then holding the movable ring and moving it downwards. The movement of the movable ring causes the screw block to move downwards, which in turn causes the movable block and other components to move downwards. At this point, the insertion post moves downwards until it penetrates the bottom of the woven bag, thus fixing the woven bag in place. This solves the problem that most materials are now received using woven bags, which are tied to the outlet with ropes. When the ropes are not tied tightly, the bags are prone to falling off.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0025] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.
[0026] This application discloses a multi-layer screening machine for processing plastic granules. (Refer to...) Figure 1-7 A multi-layer screening machine for processing plastic granules includes a multi-layer screening machine body 1. The multi-layer screening machine body 1 includes four support legs 101. A first spring 102 is fixedly connected to the top of the support legs 101. A cross frame 103 is fixedly connected to the other end of the first spring 102. There are two cross frames 103. A machine body 104 is fixedly connected to the top of the cross frames 103. A vibration motor 106 is installed at the bottom of the machine body 104. Three screens 107 are fixedly connected to the inner cavity of the machine body 104. A sliding plate 105 is fixedly connected to the bottom of the inner cavity of the machine body 104. A fixing mechanism 2 is fixedly provided on the right side of the bottom of the machine body 104.
[0027] The fixing mechanism 2 includes a support ring 201, a discharge pipe 202 is fixedly connected to the bottom of the support ring 201, a movable ring 203 is slidably connected to the surface of the discharge pipe 202, a fixing ring 204 is fixedly connected to the bottom surface of the discharge pipe 202, the top of the fixing ring 204 contacts the bottom of the movable ring 203, the surface of the fixing ring 204 is provided with six insertion holes 213, and an insertion post 214 is fixedly connected to the bottom of the movable ring 203, the insertion post 214 is inserted into the interior of the insertion hole 213.
[0028] Reference Figure 3 and Figure 4 The top of the movable ring 203 is fixedly connected with two screw blocks 205. The inner cavity of the screw block 205 is threadedly connected with a screw rod 206. The surface of the screw rod 206 is movably connected with a movable block 208. The movable block 208 fixes the fixed ring 204 and the movable ring 203. When screening plastic granules, the whole equipment will shake. The movable block 208 can firmly fix the fixed ring 204 below the movable ring 203, thereby preventing the movable ring 203 from separating from the fixed ring 204 during the screening process.
[0029] Reference Figure 4 and Figure 5 A knob 212 is fixedly connected to the surface of the screw 206, and a protective pad 207 is fixedly connected to the top of the movable block 208. The inner cavity of the protective pad 207 is movably connected to the surface of the screw 206. The protective pad 207 is made of rubber, and the top of the protective pad 207 is in close contact with the bottom of the fixed ring 204. The knob 212 provides a point of leverage for the operator, making it easier for the operator to rotate the screw 206. The protective pad 207 protects the bottom of the fixed ring 204, preventing the movable block 208 from being in close contact with the fixed ring 204 and causing wear between the bottom of the fixed ring 204 and the top of the movable block 208.
[0030] Reference Figure 5 A limiting block 209 is fixedly connected to the bottom of the screw 206. The top of the limiting block 209 contacts the bottom of the movable block 208. By setting the limiting block 209, the movable block 208 is limited, so that the movable block 208 moves more stably on the surface of the screw 206, and at the same time, the movable block 208 is prevented from falling off the surface of the screw 206, thereby preventing the movable ring 203 and the fixed ring 204 from being unable to be fixed.
[0031] Reference Figure 6 and Figure 7The top of the movable ring 203 is fixedly connected to a bottom connecting block 210, and there are two bottom connecting blocks 210. The top of the bottom connecting block 210 is fixedly connected to a snap-fit block 211. The bottom of the support ring 201 is fixedly connected to a top connecting block 215, and there are two top connecting blocks 215. The bottom of the top connecting block 215 is rotatably connected to an arc plate 217, and there are four arc plates 217. An extension plate 218 is fixedly connected to one side of the arc plate 217. The snap-fit block 211 snaps into the inside of the arc plate 217 and the extension plate 218. Through the cooperation of the arc plate 217, the extension plate 218 and the snap-fit block 211, when it is necessary to replace the woven bag, the movable ring 203 can be moved upward and the snap-fit block 211 can be snapped into the inside of the extension plate 218 and the arc plate 217 to fix the position of the movable ring 203, thereby making the replacement of the woven bag faster and more convenient.
[0032] Reference Figure 6 A rotating shaft 216 is fixedly connected to the inner cavity of the top connecting block 215. The surface of the rotating shaft 216 is rotatably connected to the inner cavity of the arc plate 217. The rotating shaft 216 supports the arc plate 217, allowing the arc plate 217 to rotate more stably inside the top connecting block 215, while preventing the arc plate 217 from detaching from the interior of the top connecting block 215.
[0033] Reference Figure 6 A support plate 220 is fixedly connected to one side of the arc plate 217 and the extension plate 218. There are four support plates 220. A second spring 219 is fixedly connected to the top of the support plate 220. There are eight second springs 219. The other end of the second spring 219 is fixedly connected to the bottom of the top connecting block 215. The support plate 220 provides support for the second spring 219, making the second spring 219 more stable. It avoids the second spring 219 not having a fixed point at the bottom, which would prevent the second spring 219 from not being able to exert its elastic effect. The second spring 219 can also quickly snap the snap-fit block 211, preventing the extension plate 218 and the arc plate 217 from being too loose and unable to fix the snap-fit block 211.
[0034] Working Principle: The multi-layer screening machine body 1 for plastic granule processing is mainly used for screening, grading, and removing impurities from plastic granules. This equipment plays a crucial role in the processing of plastic granules, improving production efficiency and ensuring product quality. When using the multi-layer screening machine body 1, first, evenly spread the opening of the woven bag on top of the fixed ring 204. Then, hold the movable ring 203 and move it downwards. The movement of the movable ring 203 drives the screw block 205 downwards. The movement of the screw block 205 drives the movable block 208 and other components downwards. At this time, the insertion post 214 moves downwards until it penetrates the bottom of the woven bag and inserts into the insertion hole 213. Then, rotate the movable block 208. The rotation of the movable block 208 drives the protective pad 207 to rotate. After rotating the protective pad 207 to the bottom of the fixed ring 204, hold the knob 212. As the knob 212 rotates, the screw 206 begins to move upward. The movement of the screw 206 drives the protective pad 207 to move until the bottom of the protective pad 207 is in close contact with the bottom of the fixed ring 204, thus fixing the fixed ring 204 and the movable ring 203. At this point, the vibration motor 106 can be started and material can be added to the feed inlet. The screened plastic granules flow from the inside of the discharge pipe 202 into the woven bag after being screened by the screen 107. When the woven bag is full of plastic granules, it needs to be replaced. At this time, the knob 212 is rotated to separate the fixed ring 204 from the movable ring 203 and move the movable ring 203 upward. The movement of the movable ring 203 drives the snap-fit block 211 to move upward until the snap-fit block 211 snaps into the inside of the arc plate 217 and the extension plate 218, and the woven bag can be replaced. After replacement, the above operation can be repeated.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
