Description

Technical Field

[0002] CPP film is the cast polypropylene film, also known as the un-stretched polypropylene film. CPP film has a wide range of applications in the packaging field. CPP film is made by blowing the molten finished plastic particles, and the corresponding plastic particles need to be mixed proportionally as raw materials first.

[0003] After retrieval, a Chinese invention patent with the publication number of CN113263654B discloses a device for mixing and proportioning raw material particles of CPP blown film, which includes a box body. Between the opposite sides of the inner wall of the box body, a granular material hopper, an antistatic agent hopper and a slip agent hopper are arranged through a partition board. The bottom of the granular material hopper is rotatably connected with a mixing material tray. The center of the bottom of the partition board is provided with a powder spraying rod. The inner wall of the box body is fixedly connected with a first mixing hopper through a fixing frame. A nozzle is arranged at a position near the top of the inner wall of the first mixing hopper. The bottom of the first mixing hopper is slidably connected with an adjusting discharge plate. The center of the bottom inside the first mixing hopper is provided with a first stirring rod. The bottom of the inner wall of the box body is fixedly connected with a second mixing hopper through a support leg. The center of the bottom of the second mixing hopper is provided with a second stirring rod. This patent solves the problems of uneven mixing of existing raw materials and the invisible increase in workload, and improves the mixing efficiency and quality.

[0004] However, the above invention has the following deficiencies: When the above patent is used, the materials fall from the leakage holes and the feeding holes and are mixed with the rest of the ingredients.

[0019] The present invention provides a CPP blown film raw material particle mixing ratio device through improvement. Compared with the prior art, it has the following improvements and advantages:

[0020] First: The present invention can first add multiple raw materials into the feeding pipe cylinder. While the feeding pipe cylinder is lifting and transporting, preliminary pre-mixing treatment is carried out, and then the materials are put into the mixing tank. The mixing tank is used to carry out in-depth mixing treatment on the materials. The stirred materials are input into the lifting pipe cylinder, and the materials are input into the feeding pipe cylinder again through the lifting pipe cylinder, so as to form a cycle to ensure the thorough mixing of the materials.

[0021] Second: When the stirring shaft rotates in the present invention, it can drive the sliding sleeve to rotate synchronously under the action of the limiting rib. Under the action of the tension spring, the ball rod on the sliding sleeve tightly abuts against the double-bevel sleeve. Since the end face of the double-bevel sleeve is a slope with a changing height, the sliding sleeve will also reciprocate in the vertical direction, increasing the stirring range; when the sliding sleeve rotates, it can drive a plurality of arc-shaped plates and extending ribs to rotate, and use them to stir the material; at the same time, since the arc-shaped plate has an arc-shaped structure, when the material falls, the arc-shaped plate can play a certain guiding role for the material. As shown in the attached drawing, since the opening formed by the upper arc-shaped plate faces upward, it can gather the material. On the contrary, the opening formed by the lower arc-shaped plate faces downward, which can play a guiding and dispersing role for the material. In this way, the falling process of the material can be made variable, which is beneficial to the mixing of the materials; when the sliding sleeve moves vertically, the tension spring can also be compressed and stretched, and the deformation of the tension spring can be used to disturb the material, thereby playing an auxiliary mixing role;

[0022] Third: When the side rod moves synchronously with a plurality of anti-blocking ball rods in the present invention, it can cooperate with the cross shaft to drive the rigid ring to move up and down reciprocally, and use the two perturbation rings to act on the corrugated discharge end pipe, causing the corrugated discharge end pipe to fluctuate, thereby effectively avoiding the blockage of the corrugated discharge end pipe;

[0023] Fourth: By controlling the rotation speeds of the servo motor and the rotary motor in the present invention, the feeding rate of the material can be adjusted to ensure that each portion of the material can be fully stirred. On the other hand, the mixing auger rod and the guiding auger in the present invention can turn the material while conveying the material, and can also indirectly play an auxiliary role in mixing the material.

[0037] The present invention will be described in detail below. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] The present invention provides an apparatus for mixing and proportioning raw material particles of CPP blown film by improvement. The technical solution of the present invention is as follows:

[0039] As Figures 1 to 10 shown, an embodiment of the present invention provides an apparatus for mixing and proportioning raw material particles of CPP blown film, including a device main body 1. A feeding pipe cylinder 4, a stirring tank 5 and a lifting pipe cylinder 2 are fixedly installed inside the device main body 1. The feeding pipe cylinder 4 and the lifting pipe cylinder 2 are both inclined, and the stirring tank 5 is vertically arranged. The feeding pipe cylinder 4, the stirring tank 5 and the lifting pipe cylinder 2 are connected to each other pairwise and form a circulating mixing mechanism. Through the above structure, multiple raw materials can be first added into the feeding pipe cylinder 4. While the feeding pipe cylinder 4 is lifting and transporting, preliminary premixing treatment is carried out, and then the material is put into the stirring tank 5. The stirring tank 5 is used to carry out deep mixing treatment on the material. The stirred material is input into the lifting pipe cylinder 2, and the material is input into the feeding pipe cylinder 4 again through the lifting pipe cylinder 2, thus forming a cycle to ensure the thorough mixing of the material. On the other hand, the lifting pipe cylinder 2 can also actively send out the material to achieve rapid blanking. It also includes;

[0040] A stirring assembly, the stirring assembly is arranged inside the stirring tank 5. The stirring assembly includes a stirring shaft 501 arranged inside the stirring tank 5 and coaxially arranged with the stirring tank 5. A double-bevel sleeve 503 is rotatably sleeved in the middle of the stirring shaft 501. The double-bevel sleeve 503 is fixed to the inner wall of the stirring tank 5 by square steel. Sliding sleeves 504 are arranged above and below the double-bevel sleeve 503, and the sliding sleeves 504 are all sleeved on the stirring shaft 501. Limiting ribs 510 are fixedly arranged at both ends of the stirring shaft 501 close to the double-bevel sleeve 503, and the limiting ribs 510 are in sliding fit with the sliding sleeves 504 in the vertical direction;

[0041] Two connecting end blocks 506 are respectively fixedly installed at positions of the stirring shaft 501 close to the two sliding sleeves 504. A tension spring 507 is fixedly connected between each connecting end block 506 and the adjacent sliding sleeve 504. The tension spring 507 is in a "shuttle" shape. A plurality of arc-shaped plates 508 distributed in an annular array are fixedly installed on the circumferential outer wall of one end of the two sliding sleeves 504 close to each other, and a plurality of extending dialing ribs 509 are fixedly connected to one side of each arc-shaped plate 508. A ball abutting rod 505 is fixedly installed on one side wall of the two sliding sleeves 504 close to each other, and the end of the ball abutting rod 505 abuts against the slope of the double-bevel sleeve 503;

[0042] The specific usage method of the stirring assembly is that when the stirring shaft 501 rotates, it can drive the sliding sleeve 504 to rotate synchronously under the action of the limiting rib 510. Under the action of the tension spring 507, the ball pressing rod 505 on the sliding sleeve 504 tightly abuts against the double-bevel sleeve 503. Since the end face of the double-bevel sleeve 503 is a slope with a changing height, the sliding sleeve 504 will also reciprocate in the vertical direction, thereby realizing an increase in the stirring range;

[0043] When the sliding sleeve 504 rotates, it can drive a plurality of arc-shaped plates 508 and extension ribs 509 to rotate, and use them to stir the material; at the same time, since the arc-shaped plate 508 has an arc-shaped structure, when the material falls, the arc-shaped plate 508 can play a certain guiding role for the material. As shown in the attachment Figure 7 As shown, since the opening formed by the upper arc-shaped plate 508 faces upward, it can play a role in collecting the material. On the contrary, the opening formed by the lower arc-shaped plate 508 faces downward, which can play a role in guiding and dispersing the material. In this way, the falling process of the material can be made variable, which is conducive to the mixing of the materials;

[0044] Finally, the tension spring 507 in the stirring assembly can also be compressed and stretched when the sliding sleeve 504 moves vertically. The deformation change of the tension spring 507 can play a disturbing role on the material, and thus play an auxiliary mixing role.

[0045] There are multiple feeding hoppers 3, and the multiple feeding hoppers 3 are fixed to the top of the device main body 1.

[0046] As a further solution of the present invention, the bottoms of the multiple feeding hoppers 3 penetrate through the top of the device main body 1 and are connected to the feeding pipe cylinder 4. A synchronous connecting rod 32 is commonly arranged above the multiple feeding hoppers 3, and a plurality of anti-blocking ball rods 31 coaxially arranged with the feeding hoppers 3 are fixedly connected to the synchronous connecting rod 32. A conical spring 34 is fixedly connected between the end of each anti-blocking ball rod 31 near the bottom and the feeding hopper 3. The conical spring 34 can play a reset role. At the same time, when the conical spring 34 itself is subjected to a force, it can generate vibrations to ensure the movement frequency of the anti-blocking ball rod 31. In the natural state, the ball end of the anti-blocking ball rod 31 is located inside the feeding pipe cylinder 4.

[0047] With the above structure, when the device is in use, various raw materials can be directly added into multiple feeding hoppers 3. When the mixing auger rod 45 rotates subsequently, the materials added into the feeding hopper 3 can be lifted towards the material discharge port 43. During this process, the mixing auger rod 45 can exert a force on the spherical end of the anti-blocking ball rod 31, causing the anti-blocking ball rod 31 to move in the vertical direction, thereby playing a role in dredging the feeding hopper 3. At the same time, when the anti-blocking ball rod 31 moves, it can also drive the conical spring 34 to move, causing the conical spring 34 to undergo reciprocating deformation, thereby exerting a force on the materials through the conical spring 34, improving the dredging effect on the feeding hopper 3 and avoiding blockage.

[0048] Furthermore, side rods 33 are fixedly connected to the ends of the synchronous connecting rod 32, and the side rods 33 are in an inverted U-shaped structure. The side rods 33 are slidably engaged with the top of the device main body 1 in the vertical direction; with the above structure, the side rods 33 can slide with the device main body 1, and play a guiding role for multiple anti-blocking ball rods 31 by means of the synchronous connecting rod 32.

[0049] Furthermore, a mixing auger rod 45 is rotatably installed inside the feeding pipe cylinder 4, and one end of the mixing auger rod 45 is connected to a rotating motor 41 through a coupling. The rotating motor 41 is fixedly connected to one end of the feeding pipe cylinder 4; with the above structure, when mixing, the rotating motor 41 operates and drives the mixing auger rod 45 inside the feeding pipe cylinder 4 to rotate, completing the feeding operation.

[0050] As a further solution of the present invention, a guiding auger 23 is rotatably installed inside the lifting pipe cylinder 2, and one end of the guiding auger 23 is connected to a servo motor 21 through a coupling. The servo motor 21 is fixed inside the lifting pipe cylinder 2. A sealing circular plate 24 is fixedly installed at one end of the guiding auger 23 close to the servo motor 21, and the diameter of the sealing circular plate 24 matches the inner diameter of the lifting pipe cylinder 2. A discharge port is opened at one end of the bottom side of the lifting pipe cylinder 2 close to the sealing circular plate 24, and a discharge box 22 is fixedly installed on the inner wall of the discharge port; by using the provided sealing circular plate 24, one end of the lifting pipe cylinder 2 can be blocked.

[0051] With the above structure, when the servo motor 21 runs forward, by driving the guiding auger 23 to rotate, the materials sent out from the mixing tank 5 are conveyed obliquely upward until they are conveyed into the feeding pipe cylinder 4 to achieve the cyclic mixing of the materials; when the servo motor 21 rotates in the reverse direction, the guiding auger 23 can convey the materials towards the discharge box 22 to achieve active discharging.

[0052] As a further solution of the present invention, a corrugated discharge end pipe 51 is fixedly connected between the mixing tank 5 and the lifting pipe cylinder 2. A rigid ring 52 is fixedly connected to the middle end of the corrugated discharge end pipe 51. Cross ribs 521 are fixedly connected to the inner side wall of the rigid ring 52. Disturbing rings 522 are fixedly installed at both the upper and lower ends of the cross ribs 521. Horizontal shafts 332 are fixedly connected to both sides of the circumferential outer wall of the rigid ring 52. The bottom end of the side rod 33 is fixedly connected to a transmission inclined rod 331, and the transmission inclined rod 331 is fixedly connected to the horizontal shaft 332.

[0053] With the above structure, when the side rod 33 moves synchronously with a plurality of anti-blocking rod balls 31, it can drive the rigid ring 52 to reciprocate up and down in cooperation with the horizontal shaft 332, and generate a force on the corrugated discharge end pipe 51 by using the two disturbing rings 522, causing the corrugated discharge end pipe 51 to fluctuate, thereby effectively avoiding the blockage of the corrugated discharge end pipe 51.

[0054] As a further solution of the present invention, a blanking port 43 is opened at one end of the bottom side wall of the feeding pipe cylinder 4 close to the rotating motor 41. A feeding box 42 is fixedly connected between the blanking port 43 and the top of the mixing tank 5. Horizontally arranged cross support rods 502 are fixedly installed on one side of the inner walls of the feeding box 42 and the mixing tank 5. The two cross support rods 502 are rotationally connected to the mixing shaft 501. A pair of meshing transmission conical teeth 44 are key-connected between the mixing shaft 501 and the mixing auger rod 45; with the above structure, the materials sent out by the feeding pipe cylinder 4 in cooperation with the mixing auger rod 45 can pass through the blanking port 43 and the feeding box 42 and fall into the mixing tank 5; at the same time, when the mixing auger rod 45 rotates, it can drive the mixing shaft 501 to rotate through the transmission of the two transmission conical teeth 44.

[0055] As a further solution of the present invention, horizontally arranged mounting cross plates 511 are fixedly installed at both ends of the mixing shaft 501 close to the double-bevel sleeve 503. The two mounting cross plates 511 form a 90-degree angle. A plurality of slow-flow hoppers 512 are fixedly installed on each mounting cross plate 511. Brush wall rods 513 in contact with the inner wall of the mixing tank 5 are fixedly installed at the ends of the two mounting cross plates 511.

[0056] With the above structure, when the mixing shaft 501 rotates, it can drive the two mounting cross plates 511 and a plurality of slow-flow hoppers 512 to rotate. When the materials fall into the slow-flow hoppers 512, they can be temporarily stored and slowly fall in a circular path when rotating around the mixing shaft 501, so that the materials received by the slow-flow hoppers 512 can be effectively mixed with the other materials; when the mounting cross plates 511 rotate, the provided brush wall rods 513 can scrape the inside of the mixing tank 5 to reduce the adhesion of materials.

[0057] As a further solution of the present invention, a plurality of staggered convex chutes 451 are provided on the circumferential outer wall of the mixing auger rod 45, and a matching slider 452 is slidably connected to the inside of each convex chute 451. A vibration spring 453 is fixedly connected between the slider 452 and the convex chute 451. A shielding plate 454 is fixedly installed on the top of each slider 452, and the arc of the shielding plate 454 matches the circumferential outer wall of the mixing auger rod 45. An extending swing piece 455 is fixedly connected to the outer side wall of each shielding plate 454, and a plurality of stirring blades 456 are fixedly connected to one end of the outer side walls on both sides of each extending swing piece 455. Through the arrangement of the shielding plate 454, it is possible to prevent materials from falling into the convex chute 451.

[0058] With the above structure, the provided slider 452 can rotate together with the shielding plate 454 and the extending swing piece 455 following the mixing auger rod 45, so as to realize the pre-mixing treatment of the materials while feeding. Since the mixing auger rod 45 is inclined, under the influence of gravity, the vibration springs 453 on both sides of each slider 452 are subjected to different forces. At the same time, as shown in the attached Figure 9 figure, the stirring blades 456 on each extending swing piece 455 are mainly concentrated on one side. Therefore, in actual use, the two vibration springs 453 will vibrate due to the factors of uneven force and the reaction force of the actual materials. While increasing the action range of the extending swing piece 455, the plurality of stirring blades 456 can exert a force on the materials in the axial direction of the mixing auger rod 45, so as to achieve the purpose of improving the pre-mixing effect.

[0059] Furthermore, support brackets 101 are fixedly installed between the lifting tube 2 and the feeding tube 4 and the device main body 1; the support brackets 101 are used to fix the lifting tube 2 and the feeding tube 4.

[0060] The specific working method is as follows: When in use, various raw materials are added into multiple feeding hoppers 3. The rotating motor 41 is started to drive the mixing auger rod 45 inside the feeding pipe barrel 4 to rotate. When the mixing auger rod 45 rotates, the materials added from the feeding hopper 3 are lifted towards the blanking port 43. During this process, the auger blades of the mixing auger rod 45 exert a force on the ball end of the anti-blocking ball rod 31, causing the anti-blocking ball rod 31 to move in the vertical direction, thus playing a role in dredging the feeding hopper 3. At the same time, when the anti-blocking ball rod 31 moves, it also drives the conical spring 34 to move, causing the conical spring 34 to undergo reciprocating deformation, thereby exerting a force on the materials through the conical spring 34, improving the dredging effect on the feeding hopper 3 and avoiding blockage; After the materials pass through the blanking port 43 and the material passing box 42 and fall into the mixing tank 5, they are deeply mixed by the mixing tank 5. The mixed materials are input into the lifting pipe barrel 2, and the materials are input into the feeding pipe barrel 4 again through the lifting pipe barrel 2, thus forming a cycle to ensure the thorough mixing of the materials. On the other hand, the lifting pipe barrel 2 also actively sends out the materials to achieve rapid blanking;

[0061] The specific process is as follows: The mixing auger rod 45 drives the mixing shaft 501 to rotate through the transmission of two driving conical teeth 44, and drives the sliding sleeve 504 to rotate synchronously under the action of the limit rib 510. Under the action of the tension spring 507, the ball rod 505 on the sliding sleeve 504 tightly abuts against the double-bevel sleeve 503. Since the end face of the double-bevel sleeve 503 is a slope with a changing height, the sliding sleeve 504 will also perform reciprocating motion in the vertical direction, thus realizing an increase in the mixing range; When the sliding sleeve 504 rotates, it drives a plurality of arc-shaped plates 508 and extension ribs 509 to rotate, and uses them to mix the materials; At the same time, because the arc-shaped plate 508 has an arc-shaped structure, when the materials fall, the arc-shaped plate 508 plays a certain guiding role for the materials, as attached Figure 7As shown, since the opening formed by the upper arc plate 508 faces upward, it plays a role in gathering the materials. On the contrary, the opening formed by the lower arc plate 508 faces downward, playing a role in guiding and dispersing the materials. Thus, the falling process of the materials becomes variable, which is beneficial to the mixing between the materials. Finally, the tension spring 507 in the stirring assembly is compressed and stretched when the sliding sleeve 504 moves vertically. The deformation change of the tension spring 507 plays a disturbing role on the materials, thereby playing an auxiliary mixing role. When the side rod 33 moves synchronously with a plurality of anti-blocking ball rods 31, it drives the rigid ring 52 to move up and down reciprocally in cooperation with the cross shaft 332, and uses the two disturbing rings 522 to exert a force on the corrugated discharge end pipe 51, causing the corrugated discharge end pipe 51 to fluctuate, thereby effectively avoiding the blockage of the corrugated discharge end pipe 51. When the servo motor 21 runs forward, it drives the material guide auger 23 to rotate, and conveys the materials sent out from the mixing tank 5 obliquely upward until they are conveyed into the feeding pipe cylinder 4 to achieve the cyclic mixing of the materials. After cyclic stirring for an appropriate time, the servo motor 21 is controlled to rotate reversely, and the material guide auger 23 conveys the materials towards the discharge box 22, and actively discharges the mixed materials from the discharge box 22 to achieve active discharging.

[0062] The provided slider 452 together with the shielding plate 454 and the extending swing piece 455 rotate along with the mixing auger rod 45. Thus, while the mixing auger rod 45 feeds the materials, it performs pre-mixing treatment on the materials. Since the mixing auger rod 45 is inclined, under the influence of gravity, the vibration springs 453 on both sides of each slider 452 receive different magnitudes of force. At the same time, as shown in the appendix Figure 9 As shown, the blades 456 on each extending swing piece 455 are mainly concentrated on one side. Therefore, in actual use, the two vibration springs 453 will vibrate due to the factors of uneven force and the reaction force of the actual materials. While increasing the action range of the extending swing piece 455, multiple blades 456 can exert a force on the materials along the axial direction of the mixing auger rod 45, thereby achieving the purpose of improving the pre-mixing effect.
