[0009] As a further solution of the present invention: a cleaning groove is provided on the side of the storage groove facing the fixed bracket. A partition is installed inside the storage groove in the cleaning groove. The partition is connected to a first lifting cylinder. The cleaning groove is connected to a guiding sliding groove.

[0011] As a further solution of the present invention: the end of the leveling plate close to the conveyor belt is inclined and a roller is provided between it and the conveyor belt. A receiving groove is provided at the end of the leveling plate close to the conveyor belt.

[0012] As a further solution of the present invention: connecting flanges are provided at both ends of the leveling plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: (1) By reciprocally controlling the reciprocating movement of the storage tank and the intermediate separation rack, the stratification of plastic particles is achieved. Among them, the particles with a diameter larger than the standard size remain in the storage tank, and those equal to or smaller than the standard size fall onto the intermediate separation rack. The reciprocating intermediate separation rack separates the plastic particles smaller than the standard size to the bottom separation rack. The plastic particles that meet the size requirements remain on the intermediate separation rack. The inclined intermediate separation rack combined with the reciprocating movement causes the plastic particles to continuously slide onto the conveyor belt, and feeding and conveying are carried out in combination with the conveyor belt.

[0015] (2) The storage tank and the intermediate separation rack are slidably and reciprocally installed in combination with the sliding rack and the installation slide rail. The angle of the installation slide rail is controlled by an inclined cylinder, so that the angles of the storage tank and the intermediate separation rack can be adjusted, and further the separation and falling speed of the plastic particles can be adjusted, avoiding the falling material speed being too fast to exceed the conveying capacity of the conveyor belt.

[0016] (3) The storage tank and the intermediate separation rack are reciprocally installed by driving through a rotating disk and an eccentric rod. Among them, the eccentric rod is electromagnetically adsorbed and connected with the storage tank in combination with a cross hinge rack and an electromagnetic adsorption block. When adjusting the angles of the storage tank and the intermediate separation rack, the connection between the electromagnetic adsorption block and the storage tank needs to be disconnected to avoid the limitation of the connection part between the electromagnetic adsorption block and the storage tank affecting the angle adjustment of the storage tank.

[0017] (4) By setting a smoothing plate, when the partition strip carrying plastic particles encounters the smoothing plate during the rising process, the partition strip will push the smoothing plate to rise. During the rising process, the receiving groove at the end of the smoothing plate levels the protruding plastic particles, and makes the protruding plastic particles slide along the edge of the partition strip, avoiding the accumulation of protruding plastic particles on the edge of the partition strip during the conveying process of the conveyor belt.

Detailed implementation manners

[0030] The technical solutions of the present invention will be further described in detail below in combination with the detailed implementation manners.

[0031] As Figure 1 、 Figure 2 shown, a granule raw material feeding device for plastic product processing includes multiple groups of conveyor belts 2 arranged around the plastic processing equipment. Partition strips 20 are evenly spaced on the conveyor belts 2. The conveyor belts 2 are rotatably installed between the mounting frame 1. The conveyor belts 2 are arranged in a step-like structure. The bottom of the conveyor belts 2 is connected with a particle uniformity mechanism 3. The conveying end of the conveyor belts 2 points to the central axis part of the plastic processing equipment. A mixing mechanism 5 is arranged on the plastic processing equipment.

[0032] As Figure 3As shown, the particle uniform mechanism 3 includes a storage groove 30, an intermediate separation frame 31, and a bottom separation frame 32. A first separation hole is provided in the storage groove 30, and a second separation hole is provided on the intermediate separation frame 31. The storage groove 30 and the intermediate separation frame 31 are slidably installed at the upper end of the mounting frame 1. The intermediate separation frame 31 is inclined towards the conveying direction of the conveyor belt 2, and the bottom separation frame 32 is inclined towards the end of the mounting frame 1 and fixedly installed on the inner side wall of the mounting frame 1.

[0033] Specifically, the number of conveyor belts 2 is set according to the types of raw materials of plastic products, and various raw material particles are conveyed through the conveyor belts 2 respectively. The plastic particles are put into the storage groove 30, and the storage groove 30 and the intermediate separation frame 31 are reciprocally controlled to move back and forth, so as to realize the layering of the plastic particles. Among them, the particles with a diameter larger than the standard size remain in the storage groove 30, and the particles equal to or smaller than the standard size fall onto the intermediate separation frame 31. The reciprocally moving intermediate separation frame 31 separates the plastic particles smaller than the standard size to the bottom separation frame 32. The plastic particles meeting the size requirements remain on the intermediate separation frame 31. The inclined intermediate separation frame 31 combined with the reciprocating motion enables the plastic particles to continuously slide onto the conveyor belt 2, and the feeding and conveying are carried out in combination with the conveyor belt 2.

[0034] Further, as Figure 3 shown, a mounting slide rail 33 is provided on the mounting frame 1. The storage groove 30 and the intermediate separation frame 31 are fixedly connected. The storage groove 30 and the intermediate separation frame 31 are slidably installed with the mounting slide rail 33 through a sliding frame 37. One end of the mounting slide rail 33 is rotatably installed with the mounting frame 1. A side chute 36 is provided on the side of the other end of the mounting slide rail 33, and an inclined air cylinder 34 is provided on the side of the mounting frame 1. A rotating slider 35 is slidably installed in the side chute 36, and the rotating slider 35 is connected to the inclined air cylinder 34.

[0035] Specifically, the storage groove 30 and the intermediate separation frame 31 are slidably reciprocally installed in combination with the sliding frame 37 and the mounting slide rail 33. The angle of the mounting slide rail 33 is controlled by the inclined air cylinder 34, so that the angles of the storage groove 30 and the intermediate separation frame 31 can be adjusted, and further the separation and falling speed of the plastic particles can be adjusted, avoiding the falling material speed being too fast to exceed the conveying capacity of the conveyor belt 2.

[0036] It should be noted that the whole composed of the storage groove 30, the intermediate separation frame 31, and the sliding frame 37 is slidably installed with the mounting slide rail 33. Therefore, the storage groove 30, the intermediate separation frame 31, and the sliding frame 37 perform reciprocating motions synchronously.

[0037] Further, as Figure 4 、 Figure 5As shown in the figure, a fixed bracket 39 is provided at the end of the mounting bracket 1. A rotating disk 310 is rotatably mounted in the middle of the fixed bracket 39. The rotating disk 310 is connected to a first motor 311. An eccentric rod 312 is rotatably mounted on the rotating disk 310. The end of the eccentric rod 312 is rotatably connected to a cross hinge bracket 313. An electromagnetic adsorption block 314 is rotatably mounted on the cross hinge bracket 313. The electromagnetic adsorption block 314 is electromagnetically adsorbed and connected to the side wall of the storage groove 30.

[0038] Specifically, the storage groove 30 and the intermediate separation frame 31 are reciprocally installed by driving the rotating disk 310 and the eccentric rod 312. Among them, the eccentric rod 312 is combined with the cross hinge bracket 313 and the electromagnetic adsorption connection between the electromagnetic adsorption block 314 and the storage groove 30. When adjusting the angles of the storage groove 30 and the intermediate separation frame 31, the connection between the electromagnetic adsorption block 314 and the storage groove 30 needs to be disconnected to avoid the limitation of the connection part between the electromagnetic adsorption block 314 and the storage groove 30 from affecting the angle adjustment of the storage groove 30.

[0039] Furthermore, as Figure 4 、 Figure 6 shown, a cleaning groove 300 is provided on one side of the storage groove 30 facing the fixed bracket 39. A partition 315 is installed inside the cleaning groove 300 of the storage groove 30. The partition 315 is connected to a first lifting cylinder 316. The cleaning groove 300 is connected to a guiding chute 38. The guiding chute 38 extends towards the upper surface of the bottom separation frame 32.

[0040] Specifically, the large-sized plastic particles separated and left in the storage groove 30 are cleaned through the cleaning groove 300. The inclination of the storage groove 30 towards the cleaning groove 300 is adjusted by combining the tilting cylinder 34. Subsequently, the partition 315 is driven to rise by combining the first lifting cylinder 316 to open the cleaning groove 300. The plastic particles in the storage groove 30 enter the bottom separation frame 32 along the guiding chute 38 after passing through the cleaning groove 300 and finally leave the end of the conveyor belt 2.

[0041] It should be noted that the bottom separation frame 32 has two functions. One is to receive the plastic particles leaking from the second separation holes on the intermediate separation frame 31, that is, the plastic particles smaller than the standard size. The inclined bottom separation frame 32 directly guides the plastic particles smaller than the standard size. The small-sized plastic particles leave the end of the conveyor belt 2 and are collected by the collection device. The other is to receive the plastic particles larger than the standard size remaining in the storage groove 30. When the plastic particles larger than the standard size are being cleaned, they slide down to the bottom separation frame 32 through the cleaning groove 300 and the guiding chute 38, and then leave the end of the conveyor belt 2 through the inclined bottom separation frame 32 and are collected by the collection device.

[0042] Furthermore, as Figure 7 、Figure 8 As shown in the figure, a leveling assembly 4 is provided at the bottom end of the inclined part of the mounting frame 1 where the conveyor belt 2 is located. The leveling assembly 4 includes mating sliding columns 40 provided on the two side mounting frames 1. A leveling plate 41 is slidably mounted on the mating sliding columns 40. The leveling plate 41 is horizontally arranged, and a counterweight 43 is provided at one end of the leveling plate 41 away from the conveyor belt 2.

[0043] Further, as Figure 8 shown in the figure, one end of the leveling plate 41 close to the conveyor belt 2 is inclined and a roller 45 is provided between the leveling plate 41 and the conveyor belt 2. A receiving groove 44 is provided at one end of the leveling plate 41 close to the conveyor belt 2.

[0044] Further, as Figure 8 shown in the figure, connecting flanges 42 are provided at both ends of the leveling plate 41. The leveling plate 41 is slidably mounted between the mating sliding columns 40 through the connecting flanges 42. Two groups of mating sliding columns 40 are symmetrically arranged, and a supporting block 400 is provided on the mating sliding columns 40.

[0045] Specifically, in order to prevent the plastic particles bulging and accumulating during the conveying process of the conveyor belt 2 from sliding off at the edge of the partition strip 20, by providing the leveling plate 41, when the partition strip 20 carrying the plastic particles encounters the leveling plate 41 during the rising process, the partition strip 20 will push the leveling plate 41 to rise. During the rising process, the receiving groove 44 at the end of the leveling plate 41 levels the bulging plastic particles and makes the bulging plastic particles slide along the edge of the partition strip 20. Among them, the edge of the leveling plate 41 reduces the frictional resistance with the surface of the conveyor belt 2 through the roller 45.

[0046] Further, as Figure 9 、 Figure 10 、 Figure 11As shown in the figure, the mixing mechanism 5 includes a receiving cylinder 50, the bottom of the receiving cylinder 50 is butted with a processing cylinder 55, the processing cylinder 55 is connected to plastic processing equipment, a circular connecting groove 501 is arranged at the bottom of the receiving cylinder 50, support sliders 502 are distributed in the circular connecting groove 501, the support sliders 502 are connected with a connecting frame 51, the connecting frame 51 is connected to a support frame 100, a second motor 53 is arranged on one of the connecting frames 51, the second motor 53 is connected with a mating gear 52, an external gear ring 54 is arranged at the bottom of the receiving cylinder 50, and the mating gear 52 meshes with the external gear ring 54. An inclined groove 500 is arranged in the receiving cylinder 50, a frustum-shaped frame 58 is fitted and installed at the central part of the inclined groove 500, the frustum-shaped frame 58 is hollow, a telescopic motor 59 is fixedly installed at the bottom of the frustum-shaped frame 58, the telescopic motor 59 is connected with a telescopic rod 510, and the telescopic rod 510 is fixedly connected to the inner surface of the upper end of the frustum-shaped frame 58. A mounting rod 56 is fixedly arranged on the inner wall of the receiving cylinder 50, a second lifting cylinder 57 is arranged on the mounting rod 56, and the second lifting cylinder 57 is fixedly connected to the upper end of the frustum-shaped frame 58.

[0047] Specifically, after the plastic particles lifted and fed by multiple conveyor belts 2 fall into the receiving cylinder 50, it is necessary to mix the plastic particles evenly before sending them into the plastic processing equipment. By rotating and installing the receiving cylinder 50, the plastic particles continuously falling into the receiving cylinder 50 are evenly mixed through the rotating receiving cylinder 50. At the same time, after receiving a certain amount, the feeding operation of the conveyor belt 2 is paused. The top of the frustum-shaped frame 58 is arched upward by the telescopic motor 59, and the frustum-shaped frame 58 is lifted as a whole by the second lifting cylinder 57. At this time, all the plastic particles in the receiving cylinder 50 will enter the plastic processing equipment through the processing cylinder 55.

[0048] The working principle of the embodiment of the present invention is: As Figures 1 - 11As shown, the number of conveyor belts 2 is set according to the types of raw materials of plastic products, and various raw material particles are conveyed through the conveyor belts 2 respectively. The plastic particles are put into the storage tank 30, and the storage tank 30 and the intermediate separation frame 31 are reciprocally controlled to move back and forth, so as to realize the stratification of the plastic particles. Among them, the particles with a diameter larger than the standard size remain in the storage tank 30, and those equal to or smaller than the standard size fall onto the intermediate separation frame 31. The reciprocally moving intermediate separation frame 31 separates the plastic particles smaller than the standard size to the bottom separation frame 32. The plastic particles that meet the size requirements remain on the intermediate separation frame 31. The inclined intermediate separation frame 31 combined with the reciprocating motion enables the plastic particles to continuously slide onto the conveyor belt 2, and the feeding and conveying are carried out in combination with the conveyor belt 2. The storage tank 30 and the intermediate separation frame 31 are slidably and reciprocally installed in combination with the sliding frame 37 and the installation slide rail 33. The angle of the installation slide rail 33 is controlled by the inclined cylinder 34, so that the angles of the storage tank 30 and the intermediate separation frame 31 can be adjusted, and further the separation and falling speed of the plastic particles can be adjusted to avoid the falling speed being too fast and exceeding the conveying capacity of the conveyor belt 2. The storage tank 30 and the intermediate separation frame 31 are reciprocally installed by the rotating disk 310 and the eccentric rod 312. Among them, the eccentric rod 312 is electromagnetically adsorbed and connected with the storage tank 30 in combination with the cross hinge frame 313 and the electromagnetic adsorption block 314. When adjusting the angles of the storage tank 30 and the intermediate separation frame 31, the connection between the electromagnetic adsorption block 314 and the storage tank 30 needs to be disconnected to avoid the limitation of the connection part between the electromagnetic adsorption block 314 and the storage tank 30 affecting the angle adjustment of the storage tank 30. The large-size plastic particles separated and left in the storage tank 30 are cleaned through the cleaning tank 300. The inclination of the storage tank 30 towards the cleaning tank 300 is adjusted in combination with the inclined cylinder 34, and then the partition plate 315 is driven to rise by the lifting cylinder 1 316 to open the cleaning tank 300. The plastic particles in the storage tank 30 enter the bottom separation frame 32 through the cleaning tank 300 and finally leave the end of the conveyor belt 2. In order to prevent the plastic particles protruding and piling up during the conveying process on the conveyor belt 2 from slipping at the edge of the partition strip 20, a leveling plate 41 is provided. When the partition strip 20 carrying the plastic particles rises and encounters the leveling plate 41, the partition strip 20 will push the leveling plate 41 to rise. During the rising process, the accommodating groove 44 at the end of the leveling plate 41 levels the protruding plastic particles and enables the protruding plastic particles to slide along the edge of the partition strip 20. Among them, the friction resistance between the edge of the leveling plate 41 and the surface of the conveyor belt 2 is reduced by the roller 45.After the plastic particles lifted and fed by multiple conveyor belts 2 fall into the receiving cylinder 50, it is necessary to mix the plastic particles evenly before sending them to the plastic processing equipment. By rotating the installation of the receiving cylinder 50, the continuously falling plastic particles in the receiving cylinder 50 are evenly mixed through the rotating receiving cylinder 50. At the same time, after receiving a certain amount, the feeding operation of the conveyor belt 2 is paused. The top of the frustum frame 58 is arched upward by the telescopic motor 59, and at the same time, the lifting cylinder II 57 drives the whole frustum frame 58 to rise. At this time, all the plastic particles in the receiving cylinder 50 will enter the plastic processing equipment through the processing cylinder 55.
