Description

Technical Field

[0001] This utility model relates to the field of plastic recycling and reuse technology, and in particular to a feeding device for recycling waste plastics. Background Technology

[0002] Waste plastic is a colloquial term and does not refer to discarded, old, or useless plastic products. The vast majority of plastic products, especially those used in large quantities for single purposes, do not undergo significant changes in the properties of the plastic material itself after use. Therefore, they can be recycled and reprocessed into plastic products for reuse. This includes plastic pellets produced from waste plastic. Since the hoppers of plastic product manufacturing equipment are often located at high positions, feeding equipment is needed to save labor and make feeding more labor-saving and time-saving. Therefore, this application discloses a feeding device for waste plastic recycling. Utility Model Content

[0003] The purpose of this invention is to address existing problems by providing a feeding device for recycling waste plastics.

[0004] This utility model is achieved through the following technical solution: A feeding device for waste plastic recycling includes a base frame, a conveyor rotatably mounted above the base frame, a hopper at one end of the conveyor, a bucket frame connected to the outside of the hopper, the bucket frame connected to one end of the base frame, an adjustment mechanism between the base frame and the conveyor, a material flow plate below the other end of the conveyor, baffles symmetrically connected to both sides of the material flow plate, and a discharge mechanism at the lower end of the hopper.

[0005] As a further improvement to the above solution, the adjustment mechanism includes a hinge seat one, which is symmetrically connected to the lower side of the conveyor near one end of the hopper and one end of the bottom frame. A hinge seat two is installed at the other end of the bottom frame. A hydraulic cylinder is installed on the hinge seat two. The working rod of the hydraulic cylinder is connected to a support lug. The support lug is rotatably connected to a support rod. Support blocks are symmetrically arranged at the ends of the support rods. The support blocks are connected to the lower side of the end of the conveyor away from the hopper. The discharge end of the conveyor is driven to rotate by a hydraulic cylinder. At the same time, the hinge seat one below the inlet end of the conveyor is used as the support origin. During the process of the discharge end of the conveyor being driven to rotate by the hydraulic cylinder, the hydraulic cylinder also rotates along with the hinge seat two and the support lug.

[0006] As a further improvement to the above solution, the material flow plate is connected to the inner side of the support block on the side close to the conveyor. By connecting the material flow plate with support blocks, the load on the material flow plate is balanced when bearing the falling plastic fragments, thereby enhancing the load-bearing capacity of the material flow plate.

[0007] As a further improvement to the above solution, the discharge mechanism includes a blocking plate connected to the lower end of the hopper. Baffles are symmetrically connected to both sides of the blocking plate. A material inlet is provided on the side of the lower end of the hopper close to the conveyor belt. A discharge plate is provided on the material inlet. Guide grooves are symmetrically arranged on the discharge plate. Bolts are provided in the guide grooves and are connected to the side wall of the hopper. A rod seat is connected to the upper edge of the discharge plate. The working rod of a cylinder is connected to the rod seat and the cylinder is connected to the bucket frame. The discharge plate is raised and lowered by a cylinder, thereby controlling the size of the discharge port to achieve the discharge volume of plastic granules. At the same time, the discharge plate is moved upward by a bolt to prevent it from leaving the discharge port. The plastic granules are discharged from the hopper onto the blockage plate and then flow onto the conveyor. In addition, when the plastic granules are on the blockage plate, they are guided by a baffle.

[0008] As a further improvement to the above solution, the conveyor is provided with a conveyor belt, and side guards are symmetrically arranged on both sides of the conveyor belt. Several partitions are arranged between the side guards, and a support rod is arranged below the upper conveyor belt used for conveying plastic. The support rod is connected to the inner side of the conveyor frame. Plastic is transported using a conveyor belt above the conveyor, and the plastic is blocked by side guards to prevent it from falling off the conveyor belt. In addition, the spacers on the conveyor belt separate the plastic in sections, which facilitates the smooth and continuous transport of plastic through the conveyor belt.

[0009] Compared with the prior art, this utility model has the following advantages: it has a simple structure, reasonable design, and novel and unique concept. It feeds plastic into the hopper, and the discharge amount of plastic is controlled by the discharge mechanism in the hopper. It is transported from low to high position by an intermittent conveyor belt. At the same time, the partition strip prevents the plastic from flowing downward. When the plastic is transported to the high position, it falls from the high end of the conveyor belt onto the flow plate. The plastic slides from the flow plate onto the processing equipment, thereby achieving the purpose of feeding. Attached Figure Description

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figure 1-4 As shown, a feeding device for recycling waste plastics includes a base frame 1, a conveyor 2 rotatably mounted above the base frame 1, a hopper 6 at one end of the conveyor 2, a bucket frame 5 connected to the outside of the hopper 6, the bucket frame 5 connected to the front end of the base frame 1, an adjustment mechanism 3 between the base frame 1 and the conveyor 2, a material flow plate 4 below the rear end of the conveyor 2, baffles 41 symmetrically connected to both sides of the material flow plate 4, and a discharge mechanism 7 at the lower end of the hopper 6.

[0016] As a further improvement to the above solution, the adjustment mechanism 3 includes a hinge seat 31, which is symmetrically connected to the lower side of the conveyor 2 near one end of the hopper 6 and the front end of the bottom frame 1. A second hinge seat 32 is installed at the rear end of the bottom frame 1. A hydraulic cylinder 33 is installed on the second hinge seat 32. The working rod of the hydraulic cylinder 33 is connected to a support lug 34. The support lug 34 is rotatably connected to a support rod 35. Support blocks 36 are symmetrically arranged at the end of the support rod 35. The support blocks 36 are connected to the lower rear end of the conveyor 2 away from the hopper 6. The discharge end of the conveyor 2 is driven to rotate by the hydraulic cylinder 33. At the same time, with the hinge seat 31 below the inlet end of the conveyor 2 as the support origin, the hydraulic cylinder 33 rotates along with the hinge seat 32 and the lug 34 as the discharge end of the conveyor 2 is driven to rotate by the hydraulic cylinder 33.

[0017] As a further improvement to the above solution, the material flow plate 4 is connected to the inner side of the support block 36 on the side close to the conveyor 2. By connecting the support block 36 to the material flow plate 4, the load on the material flow plate 4 is balanced when bearing the falling plastic fragments, thereby enhancing the load-bearing capacity of the material flow plate 4.

[0018] As a further improvement to the above scheme, the discharge mechanism 7 includes a blocking plate 72, which is connected to the lower end of the hopper 6. Baffles 73 are symmetrically connected on both sides of the blocking plate 72. A material outlet 71 is provided on the side of the lower end of the hopper 6 near the conveyor belt. A discharge plate 74 is provided on the material outlet 71. Guide grooves 77 are symmetrically provided on the discharge plate 74. Bolts 78 are provided in the guide grooves 77. Bolts 78 are connected to the side wall of the hopper 6. A rod seat 76 is connected to the upper edge of the discharge plate 74. The working rod of the cylinder 75 is connected to the rod seat 76. The cylinder 75 is connected to the bucket frame 5. The cylinder 75 controls the lifting and lowering displacement of the discharge plate 74, thereby controlling the size of the material outlet 71 to achieve the discharge amount of plastic fragments. At the same time, the bolt 78 controls the upward displacement of the discharge plate 74 to prevent the discharge plate 74 from detaching from the material outlet 71. The plastic fragments are discharged from the hopper 6 onto the blocking plate 72 and then flow onto the conveyor 2. In addition, when the plastic fragments are on the blocking plate 72, the baffle 73 guides the plastic fragments.

[0019] As a further improvement to the above solution, a conveyor belt is provided on the conveyor 2, and side guards 21 are symmetrically arranged on both sides of the conveyor belt. Several spacers 22 are arranged between the side guards 21, and a support rod 8 is provided below the upper conveyor belt used for conveying plastic. The support rod 8 is connected to the inner side of the frame 23 of the conveyor 2. Plastic is transported using the conveyor belt above the conveyor 2, and the plastic on the conveyor belt is blocked by the side guard 21 to prevent the plastic from falling off the conveyor belt from the edge. In addition, the partition strip 22 on the conveyor belt separates the plastic on the conveyor belt into sections, which facilitates the smooth and continuous transport of plastic through the conveyor belt.

[0020] The working principle of a feeding device for waste plastic recycling is as follows: Waste plastic fragments are fed into the hopper 6. The discharge plate 74 is raised and lowered by the cylinder 75 to open and close the feed port 71, causing the plastic fragments in the hopper 6 to be discharged from the feed port 71 onto the blocking plate 72. The plastic fragments discharged through the blocking plate 72 are fed to the conveyor 2, ensuring that the plastic fragments falling onto the conveyor 2 are uniform, so that the conveyor belt on the conveyor 2 is evenly loaded, and preventing the plastic fragments in the grooves between the partitions 22 on the conveyor belt from overflowing and scattering. After being transported from a low position to a high position by the conveyor 2, the plastic fragments fall from the high position onto the flow plate 4, and are then fed to the plastic product manufacturing equipment through the flow plate 4.

[0021] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
