Technical Field

[0001] The utility model relates to the technical field of plastic particle processing, and more specifically, to an automatic proportioning device for plastic particles. Background Art

[0002] Plastic particles are raw materials for storage, transportation and processing of plastics in the form of semi-finished products. Plastics are a type of polymer material. Ethylene, propylene, vinyl chloride, styrene, etc. can be produced using petroleum as raw material. The molecules of these substances can react with each other under certain conditions to form compounds with large molecular weight.

[0003] During the processing of plastic particles, different raw materials need to be mixed and stirred in a certain proportion. The mixture of raw materials in different proportions can produce plastic particles with different characteristics. The mixing ratio of the raw materials can generally be controlled by controlling the opening and closing time of the electric valve. However, in the actual use of the existing proportioning device, due to the lack of corresponding sampling mechanism, the operator cannot collect samples in time during the mixing of raw materials, which easily leads to incomplete mixing. Therefore, it is necessary to improve this. Utility Model Content

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] like Figures 1 to 6 As shown, the utility model provides an automatic proportioning device for plastic particles, comprising:

[0030] A bracket 1, a mixing cylinder 2 is fixedly sleeved inside the top of the bracket 1, and a cover plate 3 is fixedly installed on the top of the mixing cylinder 2;

[0031] The sampling mechanism 4 is arranged on the left side of the top of the cover plate 3;

[0032] The driving mechanism 5 is arranged at the left rear of the top end of the cover plate 3;

[0033] Among them, the sampling mechanism 4 includes a limiting rod 401, which is fixedly installed on the left side of the top of the cover plate 3, and the top of the outer surface of the limiting rod 401 is movably sleeved with a horizontal block 402, and the left side of the bottom end of the horizontal block 402 is fixedly installed with a vertical block 403, the bottom end of the vertical block 403 passes through the cover plate 3 and extends to the inside of the mixing barrel 2, the bottom of the outer surface of the vertical block 403 and the inner surface of the cover plate 3 are movably sleeved, and the bottom end of the inside of the vertical block 403 is movably sleeved with a sampling box 404, and the right end of the horizontal block 402 is fixedly installed with a round block 405, which will cause the vertical block 403 to move.

[0034] When the round block 405 is pushed, it will move with the horizontal block 402, so that the vertical block 403 fixedly connected to the horizontal block 402 will move downward along the inner surface of the cover 3 with the sampling box 404. The existence of the limit rod 401 can limit the movement of the horizontal block 402 to prevent the horizontal block 402 from separating from the cover 3 with the vertical block 403, so that the sampling of the plastic particles in the mixing barrel 2 can be achieved during the mixing process, thereby determining the mixing quality of the plastic particles, thereby improving the practicality and convenience of the proportioning device.

[0035] Wherein, the driving mechanism 5 comprises:

[0036] A driving motor 501, the driving motor 501 is fixedly sleeved on the rear portion of the left side of the top end of the cover plate 3, and the other end of the output shaft of the driving motor 501 is fixedly sleeved with a driving shaft 502;

[0037] The rotating rod 503 is fixedly sleeved on the right side of the outer surface of the driving shaft 502 , and the inner surface of the rotating rod 503 is movably sleeved on the outer surface of the round block 405 .

[0038] When the driving motor 501 is started, the driving shaft 502 drives the rotating rod 503 to rotate, so that the inner wall of the rotating rod 503 generates a thrust on the outer surface of the round block 405, pushing the round block 405 to move.

[0039] Among them, a first motor 6 is fixedly installed in the middle of the top of the cover plate 3, and the other end of the output shaft of the first motor 6 is fixedly sleeved with a first rotating shaft 7. The bottom end of the first rotating shaft 7 passes through the cover plate 3 and extends to the inside of the cover plate 3. A stirring rod 8 is fixedly sleeved on the outer surface of the first rotating shaft 7.

[0040] When the first motor 6 is started, the first rotating shaft 7 drives the stirring rod 8 to rotate, thereby mixing the proportioned plastic particles.

[0041] A vertical plate 9 is fixedly mounted on the rear side of the middle portion of the top end of the cover plate 3 , and a horizontal plate 10 is movably sleeved on the bottom of the outer surface of the vertical plate 9 .

[0042] The outer surface of the vertical plate 9 and the inner surface of the horizontal plate 10 are both smooth, ensuring that the horizontal plate 10 will not get stuck when moving along the outer surface of the vertical plate 9.

[0043] Among them, the interiors of the front and rear ends of the horizontal plate 10 are respectively fixedly sleeved with a proportioning box 11, the bottom end of the proportioning box 11 is fixedly installed with an electric valve 12, the bottom end of the electric valve 12 is fixedly installed with a feed pipe 13, the bottom end of the feed pipe 13 passes through the cover plate 3 and extends to the interior of the mixing barrel 2, the proportioning box 11, the electric valve 12 and the feed pipe 13 are all two in number and are symmetrical with respect to the center of the horizontal plate 10.

[0044] Due to the existence of the electric valve 12 , automatic proportioning of the plastic particles can be achieved by controlling the opening and closing time of the electric valve 12 .

[0045] A second motor 14 is fixedly mounted on the right portion of the rear side of the top end of the cover plate 3 , a second rotating shaft 15 is fixedly sleeved on the other end of the output shaft of the second motor 14 , and a half gear 16 is fixedly sleeved on the outer surface of the second rotating shaft 15 .

[0046] When the second motor 14 is started, the second rotating shaft 15 drives the half gear 16 to rotate.

[0047] A toothed plate 17 is fixedly mounted in the middle of the right end of the transverse plate 10 , and the right end of the toothed plate 17 is meshedly connected with the left end of the outer surface of the half gear 16 , so that the toothed plate 17 causes the transverse plate 10 to vibrate up and down.

[0048] When the half gear 16 rotates, due to the half-tooth design of the half gear 16, the tooth plate 17 will drive the cross plate 10 and the proportioning box 11 to vibrate up and down.

[0049] The working principle and use process of this utility model:

[0050] First, the operator puts different raw materials into the two proportioning boxes 11 respectively, and then opens the electric valve 12 to allow the different raw materials to enter the mixing barrel 2 through the feed pipe 13. Then, the ratio of the plastic particles is controlled by controlling the opening and closing time of the two electric valves 12 respectively. At the same time, the second motor 14 is started to make the second rotating shaft 15 drive the half gear 16 to rotate. Since the half gear 16 is designed in a semi-toothed style and the half gear 16 is meshed with the tooth plate 17, as the half gear 16 rotates, the tooth plate 17 will vibrate up and down with the proportioning box 11 through the cross plate 10, thereby preventing the raw materials from being blocked and affecting the accuracy of the plastic particle ratio.

[0051] After different raw materials enter the mixing barrel 2 in proportion, the first motor 6 is started, so that the first rotating shaft 7 drives the stirring rod 8 to rotate, thereby mixing and stirring the raw materials. During the mixing process, the operator starts the driving motor 501 at different time points, so that the driving shaft 502 drives the rotating rod 503 to rotate, so that the inner wall of the rotating rod 503 generates a thrust on the outer surface of the round block 405, pushing the round block 405 through the horizontal block 402 and moving the vertical block 403 and the sampling box 404 downward, so that the sampling box 404 is immersed in the raw materials, and then the driving motor 501 is started again to move the vertical block 403 and the sampling box 404 upward. The operator can determine the mixing condition of the raw materials by detecting the sample inside the sampling box 404, thereby improving the convenience and practicality of the proportioning device.
