[0032] The following disclosure provides many different implementations or examples for different ways of implementing the present invention.

[0033] Reference Figures 1 to 9As shown, the present invention provides a proportioning mechanism for plastic bottle production and processing, including a frame 1 and a partition structure 5. A funnel 2 is fixedly connected to the inner wall of the frame 1, and a connecting frame 3 is fixedly connected to the inner wall of the frame 1. A cylinder 4 is connected to the bottom end of the connecting frame 3, and a partition structure 5 is provided inside the funnel 2.

[0034] A raw material formula for the production and processing of plastic bottles includes the following raw materials:

[0035] The composition includes 80-84% polyvinyl chloride resin, 1.1-2.2% whitening agent, 10-15% ethylene propylene rubber, 2% silicone oil, 1% stabilizer, 0.8%-5% coupling agent, and 0.1% antibacterial agent.

[0036] In some embodiments of the present invention, the antibacterial agent is ammonium dihydrogen phosphate, the coupling agent is 4% by weight, the stabilizer is organotin, and the polyvinyl chloride resin is 83% by weight.

[0037] The following section will explain the specific settings and functions of its partition structure 5, cleaning structure 6, and auxiliary structure 7.

[0038] In some embodiments of the present invention, such as Figure 1 and Figure 4As shown, the partition structure 5 includes a partition plate 501, the surface of which is slidably connected to the funnel 2. A cylinder 503 is fixedly connected to the side wall of the partition plate 501. A rectangular plate 502 is slidably fitted onto the surface of the cylinder 503. A square plate 507 is fixedly connected to the inner wall of the cylinder 503. A spring is welded to the surface of the square plate 507. A slider 504 is fixedly connected to the end of the spring away from the square plate 507. A long column 508 is fixedly connected to the surface of the funnel 2. A rectangular groove 513 is formed on the arc surface of the long column 508. A connecting plate 509 is fixedly connected to the side wall of the partition plate 501. A component is rotatably connected to the surface of the connecting plate 509. A circular ring 510 has a sliding insert post 511 inside. When raw materials need to be proportioned, the bottom of the funnel 2 is first plugged with a stopper, and then the raw materials are poured into the two funnels 2 respectively. When the funnels 2 are full, a rectangular plate 502 is inserted into the surface of the cylinder 503. At this time, the rectangular plate 502 pushes the four partition plates 501, and the partition plates 501 are simultaneously inserted into the funnels 2. Since the part of the partition plate 501 inside the funnel 2 is chamfered, the resistance to insertion of the partition plate 501 can be reduced. When all the partition plates 501 are inserted, the distance between each partition plate 501 is reduced. The dimensions are precisely measured, and the amount of raw material between each partition plate 501 can be calculated. This calculation only needs to be done once, and the amounts will remain consistent thereafter. When the rectangular plate 502 is fitted onto the surface of the cylinder 503, the spring on the surface of the rectangular plate 507 will push the two sliders 504 to slide away from each other. At this time, the two sliders 504 will slide out of the cylinder 503. The sliders 504 will then press against the rectangular plate 502, preventing it from detaching from the surface of the cylinder 503 when pulled away from the funnel 2. A disc 512 is fixedly connected to the surface of the insert post 511. A spring is fixedly connected to the surface of disk 512. The end of the spring away from disk 512 is fixedly connected to ring 510. The surface of the insert post 511 has rounded corners, and a rectangular groove 513 is used for inserting the insert post 511. The inner diameter of ring 510 is adapted to the size of long post 508. The surface of connecting plate 509 has a round hole, the size of which is adapted to the size of long post 508. A round bar 505 is fixedly connected to the surface of slider 504. A baffle 506 is fixedly connected to the inner wall of cylinder 503. The baffle 506 is used to restrict the movement of round bar 505. The end of slider 504 near round bar 505 has a chamfer.

[0039] The overall effect of the partition structure 5 is as follows: when raw materials need to be proportioned, the bottom of the funnel 2 is first plugged with a stopper, and then the raw materials are poured into the two funnels 2 respectively. When the funnels 2 are full, the rectangular plate 502 is inserted into the surface of the cylinder 503. At this time, the rectangular plate 502 pushes the four partition plates 501, and the partition plates 501 will be inserted into the funnels 2 simultaneously. Since the part of the partition plate 501 inside the funnel 2 is chamfered, the resistance to insertion of the partition plate 501 can be reduced. When all the partition plates 501 are inserted, the distance between each partition plate 501 is precisely measured, and at this time, each partition plate 501... The amount of raw material between 0 and 1 can be calculated, and only needs to be calculated once; the amounts will remain consistent thereafter. When the rectangular plate 502 is fitted onto the surface of the cylinder 503, the spring on the surface of the rectangular plate 507 will push the two sliders 504 to slide away from each other. At this time, the two sliders 504 will slide out of the cylinder 503. The sliders 504 will then press against the rectangular plate 502, preventing the rectangular plate 502 from detaching from the surface of the cylinder 503 when pulled away from the funnel 2. The circular bar 505 and the baffle 506 restrict the movement of the sliders 504, thus preventing the sliders 504 from completely sliding out of the cylinder 503. When the partition plate... When 501 is inserted into the funnel 2, the connecting plate 509 on the surface of the partition plate 501 will approach the long column 508. At this time, the long column 508 will pass through the round hole on the surface of the connecting plate 509. Since the part of the insert 511 located inside the ring 510 has rounded corners, when the long column 508 is inserted, the long column 508 will squeeze the rounded corners of the insert 511, thereby squeezing the insert 511 out of the ring 510. When the rectangular groove 513 on the surface of the long column 508 approaches the insert 511, the spring on the surface of the disc 512 will pull the disc 512 to return to its original position. The disc 512 will then drive the insert 511 into the rectangular groove 513. At this time, the insert 511 will pass through the rectangular groove 513. The movement of the long column 508 is restricted. At this time, the partition plate 501 will be restricted inside the funnel 2 by the connecting plate 509, the ring 510, and the insert column 511 to prevent accidental contact that would cause the partition plate 501 to slide out of the funnel 2, thus affecting the subsequent mixing ratio. When mixing is required, the plug at the bottom of the funnel 2 is opened. At this time, the partition plate 501 is pulled out according to different mixing ratios, so that the raw materials in the funnel 2 fall from the bottom. The raw materials will fall directly into the production device through the connecting frame 3 and the cylinder 4 at its bottom. The whole structure solves the problem that before mixing, weighing often requires transporting the raw materials to the stirring and melting device, which would greatly waste production time.

[0040] In some embodiments of the present invention, such as Figure 1 and Figure 6As shown, the surface of the connecting frame 3 is provided with a cleaning structure 6, which includes a sliding plate 61. The surface of the sliding plate 61 is slidably connected to the connecting frame 3. An insert plate 62 is slidably inserted inside the sliding plate 61. A fixing block 63 is fixedly connected to the surface of the insert plate 62. An insert strip 64 is slidably inserted inside the fixing block 63. A rectangular frame 66 is fixedly connected to the surface of the insert strip 64. The surface of the rectangular frame 66 is fixedly connected to the sliding plate 61. A rectangular block 67 is slidably inserted inside the rectangular frame 66. A spring is sleeved on the surface of the insert strip 64. The two ends of the spring are fixedly connected to the fixing block 63 and the rectangular frame 66, respectively. When the raw materials fall into the connecting frame 3, since the inside of the connecting frame 3 is inclined downwards, different raw materials will slide down the inner wall and fall into the cylinder 4 to mix and fall. After the mixing is completed, the rotating rod 65 is rotated, and the rotating rod 65 will wind the rope 68 on its surface. At this time, the rope 68 will drive the slide plates 61 at both ends of the connecting frame 3 to move closer to each other. As the slide plates 61 move, the insert plate 62 will also move. At the same time, since the inner wall of the connecting frame 3 is inclined downward, when the insert plate 62 moves, the fixing block 63 on the surface of the insert plate 62 will be pulled downward by the spring on the surface of the rectangular frame 66. At this time, the insert plate 62 will always be in contact with the inner wall of the connecting frame 3. At this time, the bottom end of the insert plate 62 will scrape the material that is stuck to the inner wall of the connecting frame 3 and has not slid into the cylinder 4. The connecting frame 3 is rotatably connected to a rotating rod 65. The surface of the rotating rod 65 is fixedly connected to a rope 68. The end of the rope 68 away from the rotating rod 65 is fixedly connected to the slide plate 61. The end of the insert plate 62 near the rectangular frame 66 has a square groove. The size of the square groove is adapted to the size of the rectangular block 67. The square groove is used for the insertion of the rectangular block 67.

[0041] The overall cleaning structure 6 achieves the following effect: when raw materials fall into the connecting frame 3, because the interior of the connecting frame 3 is inclined downwards, different raw materials will slide down the inner wall and fall into the cylinder 4 to mix and fall. After the mixing is completed, the rotating rod 65 is rotated, and the rotating rod 65 will wind the rope 68 on its surface. At this time, the rope 68 will drive the sliding plates 61 at both ends of the connecting frame 3 to move closer to each other. As the sliding plates 61 move, the insert plate 62 will also move accordingly. At the same time, because the connecting frame 3... The inner wall is inclined downwards. When the insert plate 62 moves, the fixing block 63 on the surface of the insert plate 62 will be pulled downwards by the spring on the surface of the rectangular frame 66. At this time, the insert plate 62 will always be in contact with the inner wall of the connecting frame 3. At this time, the bottom end of the insert plate 62 will scrape the raw material that is stuck to the inner wall of the connecting frame 3 and has not slid into the cylinder 4. The whole structure solves the problem that the raw material will be adsorbed on the inner wall of the connecting frame 3, thus affecting the next raw material ratio. The rectangular block 67 and the square groove on the surface of the insert plate 62 are used to limit the sliding of the insert plate 62.

[0042] Example 2, based on Example 1, such as Figure 1 and Figure 9As shown, the funnel 2 has an auxiliary structure 7 inside, which includes a square column 71. The surface of the square column 71 is slidably connected to the funnel 2. A collar 72 is rotatably connected to the surface of the square column 71. A gear 76 is rotatably connected to the square column 71 relative to the collar 72. A round bar 75 is threaded into the inside of the gear 76. A conical block 74 is fixedly connected to the surface of the round bar 75. A locking block 73 is slidably inserted into one end of the funnel 2 near the square column 71. A connecting groove 77 is formed on the surface of the square column 71. First, the square column 71 is inserted into the bottom of the funnel 2. Then, the locking block 73 is inserted into the funnel 2 and simultaneously into the connecting groove 77 on the surface of the square column 71, thereby restricting the sliding of the square column 71. The bottom end of the square column 71 is close to the connecting frame 3. The square column 71 guides the material to fall, avoiding the problem that the material will break out after contacting the connecting frame 3 due to its excessive height when falling directly from the bottom of the funnel 2. Then, the conical block 74 is placed at the bottom end of the square column 71 and close to the square column 71. When the round bar 75 on the surface of the conical block 74 is inserted into the gear 76, the collar 72 is rotated. The collar 72 will drive the gear 76 to rotate. The gear 76 will pull the conical block 74 closer to the square column 71 through the round bar 75. The conical block 74 restricts the flow speed of the material. The inner wall of the collar 72 meshes with the gear 76. The connecting groove 77 is used to lock the insertion of the block 73.

[0043] The overall effect of the auxiliary structure 7 is as follows: by setting the auxiliary structure 7, the square column 71 is first inserted from the bottom of the funnel 2, and then the locking block 73 is inserted into the funnel 2 and simultaneously into the connecting groove 77 on the surface of the square column 71, thereby restricting the sliding of the square column 71. At the same time, the bottom of the square column 71 is close to the connecting frame 3, and the square column 71 plays the role of guiding the material to fall, avoiding the problem that the material will break out after contacting the connecting frame 3 due to its excessive height when it falls directly from the bottom of the funnel 2. Next, the conical block 74 is placed at the bottom of the square column 71 and close to the square column 71. When the round bar 75 on the surface of the conical block 74 is inserted into the gear 76, by rotating the collar 72, the collar 72 will drive the gear 76 to rotate. The gear 76 will pull the conical block 74 closer to the square column 71 through the round bar 75. The conical block 74 plays the role of restricting the flow speed of the material.

[0044] In this invention, by setting a partition structure, when raw materials need to be proportioned, the bottom of the funnel is first sealed with a stopper, and then the raw materials are poured into two funnels respectively. When the funnels are full, a rectangular plate is inserted into the cylindrical surface. At this time, the rectangular plate pushes four partition plates, and the partition plates are simultaneously inserted into the funnels. Since the part of the partition plate inside the funnel has a chamfer, the resistance to insertion is reduced. After all the partition plates are inserted, the distance between each partition plate is precisely measured, and the amount of raw material between each partition plate can be calculated. This calculation only needs to be done once, and the amounts will remain consistent thereafter. When the rectangular plate is fitted onto the cylindrical surface, the spring on the rectangular plate pushes two sliders to slide away from each other. At this time, the two sliders will slide out of the cylinder. The sliders will then press against the rectangular plate, preventing the rectangular plate from falling off the cylindrical surface when pulled away from the funnel. The circular strip and baffle limit the movement of the sliders, thus preventing the sliders from completely sliding out of the cylinder. When the plate is inserted into the funnel, the connecting plate on the surface of the partition plate will approach the long column. At this time, the long column will pass through the round hole on the surface of the connecting plate. Since the part of the column inside the ring has rounded corners, when the long column is inserted, the long column will squeeze the rounded corners of the column, thus squeezing the column out of the ring. When the rectangular groove on the surface of the long column approaches the column, the spring on the surface of the disc will pull the disc back to its original position. The disc will then drive the column into the rectangular groove. At this time, the column will restrict the movement of the long column through the rectangular groove. At this time, the partition plate will pass through the connecting plate and the round hole. The ring and insert are confined inside the funnel to prevent accidental contact that could cause the partition plate to slide out of the funnel, thus affecting subsequent mixing. When mixing is required, the plug at the bottom of the funnel is opened, and the partition plate is then removed according to the different mixing ratios, allowing the raw materials in the funnel to fall from the bottom. The raw materials will fall directly into the production device through the connecting frame and the cylinder at its bottom. The entire structure solves the problem that weighing before mixing often requires transporting the raw materials to the stirring and melting device, which would greatly waste production time.

[0045] In this invention, by setting up a cleaning structure, when the raw materials fall into the connecting frame, since the inside of the connecting frame is inclined downwards, different raw materials will slide down the inner wall and fall into the cylinder to mix and fall. After the mixing is completed, the rotating rod is rotated, and the rotating rod will wrap the rope on its surface. At this time, the rope will drive the slide plates at both ends of the connecting frame to move towards each other. As the slide plates move, the insert plate will also move. At the same time, since the inner wall of the connecting frame is inclined downwards, when the insert plate moves, the fixing block on the surface of the insert plate will be pulled downwards by the spring on the surface of the rectangular frame. At this time, the insert plate will always be in contact with the inner wall of the connecting frame. Then, the bottom end of the insert plate will scrape the raw materials that have not slid into the cylinder and are stuck to the inner wall of the connecting frame. The whole structure solves the problem that the raw materials will be adsorbed on the inner wall of the connecting frame, thus affecting the next raw material mixing. The rectangular block and the square groove on the surface of the insert plate are used to limit the sliding of the insert plate.

[0046] In this invention, by setting an auxiliary structure, a square column is first inserted from the bottom of the funnel. Then, a locking block is inserted into the funnel and simultaneously into the connecting groove on the surface of the square column, thereby restricting the sliding of the square column. At the same time, the bottom of the square column is close to the connecting frame, and the square column plays the role of guiding the material to fall, avoiding the problem that the material will break out after contacting the connecting frame due to its excessive height when falling directly from the bottom of the funnel. Next, a conical block is placed at the bottom of the square column and close to the square column. When the round bar on the surface of the conical block is inserted into the gear, by rotating the collar, the collar will drive the gear to rotate. The gear will pull the conical block closer to the square column through the round bar. The conical block plays the role of restricting the flow speed of the material.

[0047] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
