Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Embodiment:

[0024] Please refer to Figure 1 and Figure 2 , the present invention provides an injection molding material drying device, which is improved based on the existing dryer. The structure of the existing dryer mainly includes a box body 1, a mesh belt conveyor, electric heating rods, a feed hopper, etc. A plurality of mesh belt conveyors are installed inside the box body 1. The mesh belt conveyors are arranged parallel and staggered with each other. The electric heating rods are evenly arranged above the mesh belt conveyors. After the materials are put in, they are alternately conveyed along with the mesh belt conveyors and dried by the electric heating rods, and then discharged from the output end. The above is the prior art and will not be elaborated here.

[0025] The innovative part lies in that: a frame 5 is installed inside the box body 1 through an elastic support member 2. The frame 5 is arranged parallel above each mesh belt conveyor. Shovel blades 4 are evenly and fixedly installed on the lower surface of the frame 5. Through holes 10 aligned with the frame 5 are opened on the side wall of the box body 1. A drive plate 7 is fixedly installed on one side of each frame 5. The drive plate 7 passes through the through hole 10. A drive mechanism 8 connecting the drive plate 7 and a drive mechanism 9 driving the drive mechanism 8 are installed on the side wall of the box body 1;

[0026] The drive mechanism 9 can intermittently drive the drive plate 7 at the same time through the drive mechanism 8, so that the frame 5 and the shovel blades 4 reciprocate on the elastic support member 2. The shovel blades 4 shovel the materials conveyed on the mesh belt conveyor, playing a role of turning and loosening the materials, thereby preventing the injection molding materials from sticking tightly to each other and improving the drying efficiency.

[0027] Specifically, as Figure 3As shown in the figure, the elastic support member 2 includes a pin 21, a spring 22, and a support plate 23. The support plate 23 is fixedly installed inside the box body 1, and a support plate 23 is provided above each frame 5. The support plate 23 is provided with through holes, and the through holes are inserted with pins 21. The lower end of the pin 21 is fixedly assembled with the frame 5. The pin 21 is sleeved with a spring 22, and the spring 22 abuts between the support plate 23 and the cap of the pin 21;

[0028] The support plate 23 plays a supporting role, and the spring 22 enables the pin 21 to have an elastic restoring force upward along the through hole, so that the frame 5 has the ability to move elastically and reciprocally.

[0029] Furthermore, the support plates 23 are 2 to 4 and are evenly distributed along the material conveying direction to ensure the support strength. In addition, the through holes are 2 to 3 and are evenly distributed along the support plate 23. Correspondingly, the number of the springs 22 is the same as the number of the through holes to ensure the effectiveness of the elastic support.

[0030] Furthermore, the elastic support members 2 and the shovel blades 4 above the same belt conveyor are both inclined in the same direction, and the included angle between the inclined direction and the conveying direction is 30° to 45°; so that the reciprocating movements of the frame 5 and the shovel blade 4 are also inclined, which is beneficial to shoveling and turning the injection molding material.

[0031] Specifically, as Figure 4 shown in the figure, the transmission mechanism 8 includes a double-row sprocket 82, a sector gear 83, and a chain 84. The double-row sprocket 82 is rotatably installed on the side wall of the box body 1, and a double-row sprocket 82 is provided below each through hole 10. The adjacent double-row sprockets 82 are connected by a chain 84. A sector gear 83 is fixedly installed at the rear end of each double-row sprocket 82. A tooth groove 81 is formed on one side of the transmission plate 7, and the sector gear 83 is meshed and assembled with the tooth groove 81;

[0032] The transmission of the double-row sprocket 82 and the chain 84 can rotate the sector gear 83 at the same time. The sector gear 83 intermittently meshes with the tooth groove 81, and can push the transmission plate 7 upward or downward, so that the frame 5 and the shovel blade 4 can swing reciprocally and obliquely.

[0033] Furthermore, 1 to 3 sector gears 83 are evenly distributed in a circumferential manner at the rear end of each double-row sprocket 82. That is, when the double-row sprocket 82 rotates one week, the transmission plate 7 can be pushed one to three times accordingly, which is set according to the production requirements.

[0034] Specifically, the driving mechanism 9 includes a reduction motor 91 and a single-row sprocket 92. The reduction motor 91 is fixedly installed on the side wall of the box body 1, and the output end of the reduction motor 91 is fixedly installed with a single-row sprocket 92. The single-row sprocket 92 and the lowermost double-row sprocket 82 are connected by a chain 84;

[0035] The reduction motor 91 can rotate the single-row sprocket 92 to drive the transmission mechanism 8. Furthermore, the diameter of the single-row sprocket 92 is smaller than the diameter of the double-row sprocket 82, which plays the role of reducing speed and increasing torque to ensure driving power.

[0036] Specifically, a pair of baffles 3 are fixedly mounted on one side of each frame 5 , and the baffles 3 shield the through holes 10 ; the baffles 3 move with the frame 5 and can always shield the through holes 10 to prevent heat loss.

[0037] Specifically, a protection box 6 is installed on the side wall of the box body 1, and a transmission plate 7, a transmission mechanism 8, and a driving mechanism 9 are located in the protection box 6 to play a role of isolation and protection.

[0038] The working principle of this embodiment:

[0039] The crushed and cleaned injection molding materials are put into the box 1 of the dryer through the conveyor, transported back and forth along the mesh belt conveyor and dried by the electric heating rod; at the same time, the driving mechanism 9 and the transmission mechanism 8 can intermittently move the transmission plate 7, so that the frame 5 and the shovel blade 4 can reciprocate on the elastic support member 2 while tilting on the ground, shoveling the material transported on the mesh belt conveyor, playing the role of turning the material over and loosening it, which can further improve the drying efficiency.

[0040] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
