DETAILED DESCRIPTION
[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.
[0034] Combine the following Figures 1 to 8 The invention discloses a horizontal stirring device for mixing polypropylene particles.
[0035] like Figure 1 and Figure 2 As shown, in one embodiment, a horizontal stirring device for mixing polypropylene particles includes a stirring box 100, two rotating members 200, two stirring members 400, two pairs of adapters 300 and two transfer members 500; two stirring chambers 123 are arranged inside the stirring box 100, and the two stirring chambers 123 are horizontally adjacent; the two rotating members 200 are rotatably installed in the two stirring chambers 123, and the two rotation directions are opposite; the two stirring members 400 are respectively installed on the outer rings of the two rotating members 200, and are used to shovel and stir the particles and powder in the stirring chamber 123; the two pairs of adapters 300 are respectively installed on the inner rings of the two rotating members 200, and the two adapters 300 arranged in pairs are respectively located at the two ends of the rotating member 200; the two transfer members 500 are respectively sleeved on the two rotating members 200, and the two ends of the transfer member 500 are respectively fixed on the two adapters 300, and the transfer member 500 is used to regularly release the sputtered particles and powder.
[0036] The above-mentioned horizontal stirring device for mixing polypropylene particles puts plastic particles and modifier powder into the stirring chamber 123. When the rotating member 200 rotates, the stirring member 400 located on the outer ring of the rotating member 200 will shovel the particles and powder at the bottom of the stirring chamber 123, and then stir and mix them. During the stirring process, part of the plastic and powder will be rolled up and splashed everywhere, and the splashed particles and powder will fall on the surface of the transfer member 500, and pass through the transfer member 500 when the transfer member 500 rotates with the rotating member 200 and fall back to the bottom of the stirring chamber 123. Since there are two rotating members 200, and the two rotating members 200 rotate in opposite directions, the stirred particles and powder will contact and mix at the intersection of the two stirring chambers 123. The device can prevent powder with smaller particle size from accumulating at the bottom of the stirring chamber 123, and can regularly re-add the splashed particles and powder, so that the stirring and mixing effect is relatively better.
[0037] like Figure 3As shown, in one embodiment, the mixing box 100 includes a folding plate 110, a first bent plate 121 and a first inclined plate 122; both ends of the folding plate 110 are bent to be vertical, both ends of the first bent plate 121 are bent upward, and the center line of the first bent plate 121 is bent upward to form two mixing chambers 123 with semicircular bottoms, and a connecting chamber 124 is between the two mixing chambers 123. The first inclined plate 122 is arranged between the two side ends of the first bent plate 121 and the bent end of the folding plate 110, and a feeding pipe 130 is arranged above the connecting chamber 124, and the feeding pipe 130 passes through the outer surface of the folding plate 110.
[0038] Specifically, the two ends of the first bent plate 121 are parallel, and the part between the two ends and the middle position of the first bent plate 121 is bent to form a semicircular bottom of the stirring chamber 123, while the top of the stirring chamber 123 is arranged in a rectangular structure. The first bent plate 121 and the bent ends of the folding plate 110 are perpendicular to each other, and the first inclined plate 122 is at the same angle as the bent ends of the first bent plate 121 and the folding plate 110. Therefore, the front and rear ends of the stirring chamber 123 (the direction between the two bent ends of the folding plate 110) can be regarded as being provided with an oblique angle, and the feed pipe 130 is located between the bent ends of the first inclined plate 122 and the folding plate 110, and the two ends of the feed pipe 130 respectively pass through the bent ends of the first inclined plate 122 and the folding plate 110, so as to add plastic particles and modifier powder to the connecting chamber 124, and enter the stirring chamber 123 along the cavity.
[0039] like Figure 4 As shown, in one embodiment, the rotating member 200 includes a rotating tube 210 and a connecting rod 220; a first mounting hole 111 is opened at the bent end of the folding plate 110, and both ends of the rotating tube 210 are rotatably mounted in the two first mounting holes 111 respectively, and two groups of connecting rods 220 are provided, and each group of connecting rods 220 is provided with a plurality of connecting rods, and the connecting rods 220 are arranged in a circular array at one end of the rotating tube 210.
[0040] Furthermore, the stirring member 400 includes a second bent plate 411, a second inclined plate 412 and a stirring tooth 420; multiple second bent plates 411 are arranged in a ring array, and the two ends of the second bent plate 411 are respectively fixed on two connecting rods 220, the second bent plate 411 is arranged in an arc structure, and is movably fitted with the bottom of the stirring chamber 123, and second inclined plates 412 are arranged at both ends of the second bent plate 411, and the surface of the second inclined plate 412 is movably fitted with the surface of the first inclined plate 122, and each second bent plate 411 is provided with a plurality of stirring teeth 420 at one end facing the rotating tube 210, and the plurality of stirring teeth 420 are arranged at intervals along the length direction of the second bent plate 411.
[0041] Specifically, the second bent plate 411 and the second inclined plate 412 are integrally arranged, and the second bent plate 411 and the second inclined plate 412 are both arranged as arc-shaped plate structures, and when the rotating tube 210 rotates, the second bent plate 411 can scoop up the particles and powder located on the first bent plate 121, and the second inclined plate 412 can scoop up the particles and powder located on the first inclined plate 122.
[0042] In one embodiment, the stirring teeth 420 are arranged in a triangular structure, and a rounded corner is arranged at one end of the stirring tooth 420 away from the second bent plate 411. There is a certain angle between the surface of the stirring tooth 420 and the rotating surface of the rotating tube 210, and multiple stirring teeth 420 on the same second bent plate 411 are symmetrically arranged about the middle line of the second bent plate 411.
[0043] Specifically, since the stirring teeth 420 are inclined and the stirring teeth 420 on both sides of the second bent plate 411 are symmetrical, when the rotating tube 210 rotates, the particles and powder in the stirring chamber 123 will be pushed toward the connecting chamber 124 by the pushing influence of the symmetrically arranged stirring teeth 420, and the particles and powder will gather in the middle of the connecting chamber 124 during the pushing process. When the rotating tube 210 rotates in the opposite direction, the particles and powder in the stirring chamber 123 will be pushed away from the connecting chamber 124, and the particles and powder will be diverted to the front and rear ends of the stirring chamber 123 during the pushing process.
[0044] like Figure 5 As shown, in one embodiment, the horizontal stirring device for mixing polypropylene particles also includes a driving shaft 610, a driving wheel 620, a driven wheel 630 and a transmission belt 640; the two driving wheels 620 are respectively installed at the ends of the two rotating tubes 210, the driving shaft 610 is located between the two rotating tubes 210 and is installed on the folding plate 110, the driven wheel 630 is installed on the driving shaft 610, the driving wheel 620 and the driven wheel 630 are connected by the transmission belt 640, and the driving shaft 610 is connected to the driving motor.
[0045] like Figure 6 As shown, in one embodiment, the adapter 300 includes a positioning ring 310 and a fastener 320; a plurality of long holes 311 are provided on the outer ring of the positioning ring 310, and the plurality of long holes 311 are arranged in a ring array, and a plurality of pairs of second mounting holes 312 are provided on the surface of the positioning ring 310 along the central axis direction, and each pair of second mounting holes 312 penetrates and communicates with the long hole 311, and a plurality of connecting rods 220 are respectively inserted into the plurality of long holes 311, and when the connecting rod 220 abuts against one end of the long hole 311, the fastener 320 is installed in a second mounting hole 312 close to the connecting rod 220, for fixing the connecting rod 220.
[0046] Specifically, the positioning ring 310 is configured as a tubular structure. In the present embodiment, the long hole 311 may also be referred to as a waist hole. Unlike the traditional waist hole, the waist hole surface in the present embodiment is configured in an arc-shaped structure. Therefore, the central axes of the two ends of the waist hole are compared to one point, and the point is located at the exact center of the positioning ring 310. Since the positioning ring 310 is configured as a tubular structure, the long hole 311 opened on the outer ring of the positioning ring 310 will pass through to the inner ring of the positioning ring 310, and one side of the connecting rod 220 can simultaneously abut against one end of the two long holes 311. At this time, the fastener 320 is installed in a second mounting hole 312 close to the connecting rod 220, so that one side of the fastener 320 can abut against the connecting rod 220, thereby completing the fixation of the connecting rod 220 and effectively avoiding the stress deformation caused by the excessive length of the connecting rod 220, thereby making the strength of the stirring device higher.
[0047] like Figure 7 As shown, in one embodiment, the transfer member 500 also includes a plurality of positioning rods 330, which are arranged in a circular array, and the two ends of the positioning rods 330 are respectively inserted into two second mounting holes 312 where fasteners 320 are not installed, and a slot 331 is provided on the side of the positioning rods 330 away from the rotating tube 210.
[0048] Further, such as Figure 8 As shown, the transfer member 500 includes a plurality of first curved plates 510 and a plurality of second curved plates 520; the plurality of first curved plates 510 and the plurality of second curved plates 520 are arranged in a circular array, and are cross-arranged and connected to each other, the radius of the first curved plate 510 is greater than the radius of the second curved plate 520, and a second storage space 540 is formed between the inner surface of the first curved plate 510 and two adjacent second curved plates 520, and a first storage space 530 is formed between the outer surface of the second curved plate 520 and two adjacent first curved plates 510.
[0049] Specifically, the inner surface of the first arc plate 510 is fitted on the slot 331, and the multiple slots 331 respectively form a limit for the multiple first arc plates 510. When the rotating tube 210 rotates, the particles and powder sputtered in the stirring chamber 123 will fall on the outer circle of the transfer member 500, that is, the multiple first storage spaces 530, and enter the stirring chamber 123 along the side away from the two stirring chambers 123 during the rotation of the transfer member 500.
[0050] In one embodiment, a plurality of discharge holes 511 are provided on the surface of the first curved plate 510 for discharging particles and powder in the second storage space 540 from the discharge holes 511, and a plurality of feed ports 521 are provided on the surface of the second curved plate 520 at intervals in a linear direction for particles and powder in the first storage space 530 to enter the second storage space 540 from the feed ports 521.
[0051] Specifically, when the rotating tube 210 rotates, the particles and powder sputtered in the stirring chamber 123 will fall on the outer circle of the transfer member 500, that is, multiple first storage spaces 530. Since the bottom of the first storage space 530 has multiple feed ports 521, the particles and powder will enter the inner circle of the transfer member 500 along the feed ports 521 and directly fall into the second storage space 540. They will slide along the inner surface of the transfer member 500 to the second storage space 540, and finally fall back into the bottom of the stirring chamber 123 along the discharge hole 511 set at the bottom of the second storage space 540. This structural setting makes the mixing of particles and powders relatively regular, and avoids the concentration of particles or powders at a certain position in the stirring chamber 123, resulting in uneven mixing.
[0052] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0053] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
