Technical Field

[0001] The invention relates to the technical field of plastic product manufacturing, and in particular to a mixing and feeding device and method for plastic product particle batching. Background Art

[0002] In the patent "A mixing and feeding device for plastic product granule batching" with publication number "CN110790039B", the solution not only improves the mixing efficiency of plastic product granules by directly adding plastic product granules into the mixing drum, and under the toggling of a plurality of inclined buffer plates connected to the rotating rod, but also cooperates with the screening holes on the side wall of the mixing drum to screen the plastic product granules, and large particles of plastic products fall into the bottom of the mixing drum and meet the particle requirements under the crushing of the crushing plate, thereby ensuring the quality of the mixed feeding of plastic product granules. However, the solution still has the following defects:

[0003] The diameter of the screening hole is fixed. When filtering plastic product particles, any plastic product particles larger than the screening hole will flow to the bottom of the mixing barrel and be crushed. This will result in a large number of large-particle plastic products accumulating on the upper end of the crushing plate. The crushing plate has different grinding pressures on different large-particle plastic products, which affects the crushing effect of different large-particle plastic products.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Reference Figure 1 - Fig. 9 A mixing and feeding device for plastic product granule batching comprises a mixing box 1, a mixing chamber 2 is provided at the bottom of the mixing box 1, and the mixing chamber 2 is circular.

[0037] The material discharge mechanism includes a plurality of annular grooves 3 provided in the mixing chamber 2, the plurality of annular grooves 3 are distributed from top to bottom, the inner wall of the annular groove 3 is slidably connected with a first ring 4 that can rotate, the inner wall of the first ring 4 is fixedly connected with a conical ring 5, the side wall of the conical ring 5 is provided with a plurality of filter holes 6, the inner bottom wall of the conical ring 5 is fixedly connected with a second ring 9, and the top of the mixing box 1 is rotatably connected with a first rod 7 (combined with Figure 2 and Figure 8 ), the side wall of the first rod 7 is fixedly connected with a crushing wheel 8 corresponding to the multiple second rings 9, the inner wall of the second ring 9 is fixedly connected with a multiple crushing teeth 10 corresponding to the crushing wheel 8, and the diameters of the filter holes 6 on the multiple conical rings 5 ​​decrease from top to bottom.

[0038] The diameters of the filter holes 6 on the multiple conical rings 5 ​​decrease from top to bottom, so the filter holes 6 from top to bottom can filter plastic products of different sizes. At this time, the large-particle plastic products blocked by the filter holes 6 will roll down to the top of the crushing wheel 8 at the filter hole 6. The rotating crushing wheel 8 and multiple crushing teeth 10 can crush the large-particle plastic products, and the diameters of the plastic product particles blocked by the multiple conical rings 5 ​​decrease from top to bottom. Then, the distance between the crushing wheel 8 and the multiple crushing teeth 10 from top to bottom can be set, so that the blocked plastic products of different particles can be better crushed. At the same time, the crushing wheel 8 and the multiple crushing teeth 10 located at the bottom can crush the plastic products into particles of the required size, avoiding the fixed diameter of the screening hole in the prior art. When filtering the plastic product particles, at this time, as long as the plastic product particles larger than the screening hole will flow to the bottom of the mixing barrel and be crushed, which leads to the accumulation of more large-particle plastic products at the upper end of the crushing plate. The crushing plate has different grinding pressures on different large-particle plastic products, which affects the crushing effect of different large-particle plastic products.

[0039] The inner wall of the mixing chamber 2 is fixedly connected with a plurality of partitions 36 (such as Figure 3As shown), the cross-section of the partition 36 is triangular, the side wall of the partition 36 is in contact with the side wall of the first rod 7, the lower surface of the partition 36 is close to the inner wall of the corresponding conical ring 5, and two feed pipes 43 are fixedly connected to the upper part of the inner wall of the mixing box 1. It should be noted that the two feed pipes 43 are both located above the uppermost conical ring 5, and different plastic products can be fed into the area above the uppermost conical ring 5 through the two feed pipes 43.

[0040] When the first ring 4 rotates, the discharge areas corresponding to the discharge ports of the two feed pipes 43 can be changed, so that different plastic products are filtered in a disordered manner and plastic products of different qualities are better mixed. At the same time, the first ring 4 rotates, and the partition 36 can scrape the plastic products on the upper surface of the conical ring 5 into strips to avoid their accumulation and inconvenience in discharge.

[0041] It also includes a driving mechanism, which includes a through groove 11 opened on the inner wall of the annular groove 3, the inner wall of the through groove 11 is rotatably connected to a second rod 12, the side wall of the second rod 12 is fixedly connected to a gear 13, the outer wall of the first ring 4 is fixedly connected to a gear ring 14 meshing with the gear 13, the upper end of the mixing box 1 is fixedly connected to a motor 15 through a bracket, and the movable end of the motor 15 is fixedly connected to the upper end of the second rod 12.

[0042] The first rod 7 is provided with a rotating mechanism, which includes a fixed plate 16 fixedly connected to the upper end of the first rod 7, a plurality of first grooves 17 are provided on the side wall of the fixed plate 16, a T-shaped plate 18 is sealingly and slidably connected to the inner wall of the first groove 17, the side wall of the T-shaped plate 18 is elastically connected to the inner wall of the first groove 17 through a first spring 19, an arc plate 20 is fixedly connected to the side wall of the T-shaped plate 18 away from the first spring 19, and an arc groove 21 (such as Figure 5 shown).

[0043] A first wheel 22 is fixedly connected to the side wall of the movable shaft of the motor 15, a second groove 23 is opened at the upper end of the mixing box 1, a first block 24 is slidably connected to the inner wall of the second groove 23, and a second wheel 25 is rotatably connected to the upper end of the first block 24 through a rotating shaft, and a synchronous belt 26 is connected between the first wheel 22, the second wheel 25 and the multiple arc grooves 21.

[0044] When the multiple arc plates 20 slide synchronously toward each other or slide synchronously away from each other, the diameter of the approximately circular driving member formed by the multiple arc plates 20 will increase. At this time, the rotation speed of the fixed plate 16 can be changed, and the rotation speed of the first rod 7 can be adjusted. In this way, the rotation speed of the crushing wheel 8 can be adjusted, and corresponding adjustments can be made when crushing plastic products of different softness.

[0045] It should be noted that, although the plurality of arc-shaped plates 20 form a nearly circular driving member, the synchronous belt 26 will still fit with the inner walls of the plurality of arc-shaped grooves 21 , and will not affect the rotation of the fixed disk 16 .

[0046] The mixing box 1 is provided with an adjustment mechanism (such as Figure 7 As shown), the regulating mechanism includes an oil pump frame 30 fixedly connected to the side wall of the mixing box 1, the inner wall of the oil pump frame 30 is sealed and slidably connected with a first plate 31, the upper end of the mixing box 1 is fixedly connected with a rotary joint 27 through a bracket, the upper end of the fixed plate 16 is connected with a metal tube 28, the upper end of the metal tube 28 is fixedly connected to the lower end of the rotary joint 27, the inner wall of the metal tube 28 is connected to the inner wall of the first groove 17 through a first tube 29, and the inner wall of the oil pump frame 30 is fixedly connected to the upper end of the rotary joint 27 through a second tube 32.

[0047] The side wall of the oil pump frame 30 is fixedly connected to an electric push rod 33 through a support plate, and the output end of the electric push rod 33 is fixedly connected to a C-shaped rod 34. The side wall of the C-shaped rod 34 away from the electric push rod 33 is fixedly connected to the side wall of the first plate 31, and the side wall of the first plate 31 is fixedly connected to the side wall of the first block 24 through a connecting rod 35.

[0048] When it is necessary to slide multiple arc-shaped plates 20 synchronously, the electric push rod 33 is adjusted to extend, and the first plate 31 is driven to move outward through the U-shaped rod 34 (such as Figure 7 As shown), the oil pump frame 30 then absorbs oil from the multiple first grooves 17 through the second pipe 32, the rotary joint 27, the metal pipe 28 and the multiple first pipes 29. At this time, the multiple arc plates 20 approach each other under the action of the multiple first springs 19 and the hydraulic oil. At this time, the multiple arc plates 20 form a circular driving member that is reduced, speeding up the rotation speed of the first rod 7 and the crushing wheel 8, but at this time, the first plate 31 will drive the first block 24 to move outward through the connecting rod 35 (as shown in FIG. Figure 7 As shown), the synchronous belt 26 is tensioned to ensure that the fixed disk 16 can rotate;

[0049] When the multiple arc-shaped plates 20 need to be slid away synchronously, the electric push rod 33 is adjusted to retract, and the first plate 31 is driven to move inwards through the U-shaped rod 34 (such as Figure 7 As shown), the oil pump frame 30 pumps oil from the first grooves 17 through the second tube 32, the rotary joint 27, the metal tube 28 and the first tubes 29. At this time, the arc plates 20 move away from each other under the pressure of the oil. At this time, the arc plates 20 form a circular driving member that increases, reducing the rotation speed of the first rod 7 and the crushing wheel 8. However, at this time, the first plate 31 drives the first block 24 to move inward through the connecting rod 35 (as shown in FIG. Figure 7 As shown), loosen the synchronous belt 26 to ensure that the fixed plate 16 can rotate.

[0050] It should be noted that, due to the provision of the adjustment mechanism, the rotational speeds of the crushing wheel 8 and the plurality of crushing teeth 10 are inconsistent, so that the extrusion forces applied to the plastic products during crushing are different, thereby crushing them better.

[0051] like Fig. 9As shown, a dredging mechanism is provided on the partition 36, and the dredging mechanism includes two third grooves 37 opened at the lower end of the partition 36, and the inner wall of the third groove 37 is sealed and slidably connected with the second plate 38, and a fourth groove 39 connected with the two third grooves 37 is opened in the partition 36, and a reciprocating thread 40 is opened on the side wall of the first rod 7 located in the fourth groove 39, and the side wall of the reciprocating thread 40 is connected to the second block 41, and the side wall of the second block 41 is rotatably connected to the side wall of the second plate 38 close to it through a rotating rod 42.

[0052] During the rotation of the first rod 7, the reciprocating thread 40 drives the second block 41 to move up and down. At this time, the second block 41 will drive the two second plates 38 to slide up and down on the inner walls of the two third grooves 37 respectively through the two rotating rods 42. At this time, the third grooves 37 can blow air into the corresponding multiple filter holes 6 to avoid plastic products being blocked in the filter holes 6 and affecting the filtering effect. In addition, as the conical ring 5 rotates, the inside of all the filter holes 6 on the conical ring 5 can be cleaned.

[0053] A mixing and feeding method for plastic product granule batching, comprising the following steps;

[0054] S1, adding different plastic products into the mixing chamber 2 through two feeding pipes 43;

[0055] S2, start the motor 15, the motor 15 rotates through the second rod 12, the plurality of gears 13 and the plurality of gear rings 14 to drive the first ring 4 to rotate, drive the plurality of conical rings 5 ​​to rotate, speed up the filtration of the plastic products on the conical rings 5, and can also mix different plastic products;

[0056] S3, the motor 15 rotates through the first wheel 22, the second wheel 25, the synchronous belt 26 and the multiple arc-shaped grooves 21 to drive the fixed plate 16 to rotate, drive the first rod 7 to rotate, drive the crushing wheel 8 to rotate, and then the crushing wheel 8 and the multiple crushing teeth 10 can crush the large particles of plastic products and flow out;

[0057] S4. The staff collects the mixed plastic products at the bottom of the mixing chamber 2.

[0058] When mixing different plastic products, firstly, different plastic products are added into the mixing chamber 2 through two feeding pipes 43, and at this time, different plastic products are located in two areas on the conical ring 5;

[0059] The motor 15 is started, and the motor 15 rotates through the second rod 12, the plurality of gears 13 and the plurality of gear rings 14 to drive the plurality of first rings 4 to rotate, and then the plurality of conical rings 5 ​​rotate. Under the action of the partition 36, the discharge area corresponding to the discharge port of the two feed pipes 43 can be changed, so that different plastic products are filtered in a disordered manner, and plastic products of different qualities are better mixed. At the same time, the first ring 4 rotates, and the partition 36 can scrape the plastic products on the upper surface of the conical ring 5 into a strip shape to prevent them from piling up and being inconvenient to discharge;

[0060] At the same time, the motor 15 rotates through the first wheel 22, the second wheel 25, the synchronous belt 26 and the plurality of arc-shaped slots 21 to drive the fixed plate 16 to rotate, thereby driving the first rod 7 to rotate and driving the crushing wheel 8 to rotate;

[0061] Since the diameters of the filter holes 6 on the multiple conical rings 5 ​​decrease from top to bottom, the filter holes 6 from top to bottom can filter plastic products of different sizes. At this time, the large particles of plastic products blocked by the filter holes 6 will roll over the crushing wheel 8 at the filter holes 6. The rotating crushing wheel 8 and the multiple crushing teeth 10 can crush the large particles of plastic products. The diameters of the plastic product particles blocked by the multiple conical rings 5 ​​decrease from top to bottom, and the distance between the crushing wheel 8 and the multiple crushing teeth 10 from top to bottom can be set, so that the blocked plastic products of different particles can be better crushed.

[0062] When the rotation speed of the crushing wheel 8 is adjusted according to the softness of the plastic product, it is only necessary to adjust the diameter of the approximately circular driving member composed of the multiple arc plates 20, that is, to adjust the multiple arc plates 20 to slide closer or farther synchronously;

[0063] When it is necessary to slide multiple arc-shaped plates 20 synchronously, the electric push rod 33 is adjusted to extend, and the first plate 31 is driven to move outward through the U-shaped rod 34 (such as Figure 7 As shown), the oil pump frame 30 then absorbs oil from the multiple first grooves 17 through the second pipe 32, the rotary joint 27, the metal pipe 28 and the multiple first pipes 29. At this time, the multiple arc plates 20 approach each other under the action of the multiple first springs 19 and the hydraulic oil. At this time, the multiple arc plates 20 form a circular driving member that is reduced, speeding up the rotation speed of the first rod 7 and the crushing wheel 8. At this time, the first plate 31 will drive the first block 24 to move outward through the connecting rod 35 (as shown in FIG. Figure 7 As shown), the synchronous belt 26 is tensioned to ensure that the fixed disk 16 can rotate;

[0064] When the multiple arc-shaped plates 20 need to be slid away synchronously, the electric push rod 33 is adjusted to retract, and the first plate 31 is driven to move inwards through the U-shaped rod 34 (such as Figure 7As shown), the oil pump frame 30 pumps oil from the multiple first grooves 17 through the second tube 32, the rotary joint 27, the metal tube 28 and the multiple first tubes 29. At this time, the multiple arc plates 20 move away from each other under the pressure of the oil. At this time, the multiple arc plates 20 form a nearly circular driving member, which increases and reduces the rotation speed of the first rod 7 and the crushing wheel 8. At this time, the first plate 31 will drive the first block 24 to move inward through the connecting rod 35 (as shown in FIG. Figure 7 As shown), loosen the synchronous belt 26 to ensure that the fixed plate 16 can rotate;

[0065] During the rotation of the first rod 7, the reciprocating thread 40 drives the second block 41 to move up and down. At this time, the second block 41 drives the two second plates 38 to slide up and down on the inner walls of the two third grooves 37 through the two rotating rods 42. At this time, the third grooves 37 can blow air into the corresponding multiple filter holes 6 to avoid plastic products being blocked in the filter holes 6 and affecting the filtering effect. In addition, as the conical ring 5 rotates, the inside of all the filter holes 6 on the conical ring 5 can be cleaned;

[0066] Finally, the staff can collect the mixed and crushed plastic products at the bottom of the mixing chamber 2.

[0067] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
