Description

Technical Field

[0001] This utility model relates to the field of ABS granule processing technology, and in particular to a spreading device for drying ABS plastic granules. Background Technology

[0002] ABS is a high-strength, tough, and easily processed thermoplastic polymer material. It is a slightly yellow solid with a certain degree of toughness.

[0003] ABS granules need to be cooled and cut, and the cut granules need to be dried. Therefore, the collected ABS granules need to be spread out to ensure uniform and effective drying. Existing spreading devices can only spread ABS granules simply. They cannot adjust the outlet opening size in time when material accumulates at the feed port. When there are too many granules, some material will accumulate at both ends of the flat plate, which cannot be effectively cleaned and affects the drying effect. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a spreading device for drying ABS plastic granules.

[0005] This utility model is achieved through the following technical solution:

[0006] A spreading device for drying ABS plastic granules includes a conveyor belt, a scraper, columns, a hopper, a first screw, and a material control mechanism. The scraper is fixedly mounted on both sides of the upper surface of the conveyor belt, the columns are fixedly mounted on both sides of the conveyor belt, the hopper is fixedly mounted on the top inner side of the columns, the first screw is fixedly mounted on the bottom sides of the hopper, and the material control mechanism is sleeved on the outer side of the bottom of the hopper. The material control mechanism includes a lifting sleeve, a second screw, a flat plate, a clamping seat, a cylinder seat, a cylinder, a connecting block, an insert plate, and a sensing mechanism. The lifting sleeve is sleeved on the outer side of the bottom of the hopper, the second screw is fixedly mounted on the outer side of the lifting sleeve, the flat plate is sleeved on the outer side of the second screw, the clamping seat is fixedly mounted on the bottom of the lifting sleeve, the cylinder seat is fixedly mounted on the outer side of the lifting sleeve, the cylinder is connected to the cylinder seat, the connecting block is fixedly mounted on the telescopic end of the cylinder, the insert plate is fixedly mounted on the bottom of the connecting block, and the sensing mechanism is fixedly mounted on the bottom of the clamping seat.

[0007] In a preferred embodiment of the present invention, the sensing mechanism includes a connecting seat, a retaining shaft, a folding plate, a contact plate, and a spring. The folding plate is movably connected to the connecting seat via the retaining shaft. The contact plate is fixedly disposed on the back of the connecting seat, and the spring is disposed between the folding plate and the contact plate.

[0008] When material accumulates at the bottom of the lifting sleeve, the accumulated material pushes the folding plate, causing it to contact the contact plate, generating a control signal that controls the hydraulic cylinder to retract, thereby moving the insert plate and reducing the size of the discharge port at the bottom of the lifting sleeve, thus achieving the effect of controlling the discharge speed.

[0009] In a preferred embodiment of this utility model, the connecting seat is fixedly disposed at the bottom of the card seat, and the back of the folding plate is provided with a card hole that cooperates with the spring.

[0010] In a preferred embodiment of this utility model, the conveyor belt has discharge holes at both ends, and the bottom of the scraper is in contact with the surface of the conveyor belt.

[0011] The scraper removes the material accumulated on both sides of the conveyor belt after the particles are leveled, and discharges and collects it through the discharge hole, thus ensuring that only the leveled particles are left on the surface of the conveyor belt, which facilitates the drying process.

[0012] In a preferred embodiment of this utility model, the surface of the lifting sleeve is provided with a waist-shaped hole that mates with the first screw, and the surface of the flat plate is provided with a waist-shaped hole that mates with the second screw.

[0013] The height adjustment of the lifting sleeve is mainly used to adjust the distance between the bottom discharge port and the conveyor belt, thereby adjusting the discharge speed and discharge height. The height adjustment of the flat plate is mainly used to adjust the thickness of the flattened particles to adapt to the drying equipment.

[0014] In a preferred embodiment of this utility model, the top of the card holder is provided with a slot that mates with the insert plate, and the insert plate is fitted to the bottom of the lifting sleeve.

[0015] The beneficial effects of this utility model are:

[0016] This ABS plastic granule drying spreading device effectively controls the discharge speed, discharge material height, and thickness of the ABS granules after spreading. It can also control the movement of the bottom plate in real time according to the material accumulation state at the discharge port to change the discharge speed. After spreading, the accumulation areas at both ends of the granules are cleaned in time, which effectively ensures that the granules are spread evenly and thus ensures the drying effect.

Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0024] like Figure 1-5 The illustrated spreading device for drying ABS plastic granules includes a conveyor belt 1, a scraper 2, a column 3, a hopper 4, a first screw 5, and a material control mechanism 6. The scraper 2 is fixedly mounted on both sides of the upper surface of the conveyor belt 1, the column 3 is fixedly mounted on both sides of the conveyor belt 1, the hopper 4 is fixedly mounted on the top inner side of the column 3, the first screw 5 is fixedly mounted on the bottom sides of the hopper 4, and the material control mechanism 6 is sleeved on the outer side of the bottom of the hopper 4. The material control mechanism 6 includes a lifting sleeve 61, a second screw 62, a flat plate 63, a clamping seat 64, a cylinder seat 65, and a cylinder 66. The system includes a connecting block 67, an insert plate 68, and a sensing mechanism 69. A lifting sleeve 61 is fitted onto the outer side of the bottom of the hopper 4. A second screw 62 is fixedly installed on the outer side of the lifting sleeve 61. A flat material plate 63 is fitted onto the outer side of the second screw 62. A card seat 64 is fixedly installed at the bottom of the lifting sleeve 61. A cylinder seat 65 is fixedly installed on the outer side of the lifting sleeve 61. A cylinder 66 is connected to the cylinder seat 65. A connecting block 67 is fixedly installed at the telescopic end of the cylinder 66. An insert plate 68 is fixedly installed at the bottom of the connecting block 67. A sensing mechanism 69 is fixedly installed at the bottom of the card seat 64.

[0025] Specifically, the sensing mechanism 69 includes a connecting seat 691, a retaining shaft 692, a folding plate 693, a contact plate 694, and a spring 695. The folding plate 693 is movably connected to the connecting seat 691 via the retaining shaft 692. The contact plate 694 is fixedly disposed on the back of the connecting seat 691. The spring 695 is disposed between the folding plate 693 and the contact plate 694. The connecting seat 691 is fixedly disposed at the bottom of the retaining seat 64. The back of the folding plate 693 has a retaining hole that mates with the spring 695. The conveyor belt 1 has material dropping holes at both ends. The bottom of the scraper 2 contacts the surface of the conveyor belt 1. The lifting sleeve 61 has a waist-shaped hole that mates with the first screw 5. The flat plate 63 has a waist-shaped hole that mates with the second screw 62. The top of the retaining seat 64 has a slot that mates with the insert plate 68. The insert plate 68 is attached to the bottom of the lifting sleeve 61.

[0026] In this embodiment, the height of the material control mechanism 6 and the height of the flat plate 63 are adjusted. After loosening the fixing screw on the surface of the first screw 5, the height of the lifting sleeve 61 can be adjusted according to the oblong hole on the surface of the lifting sleeve 61 to ensure that the distance from the bottom outlet to the surface of the conveyor belt 1 is reasonable. Then, the height of the flat plate 63 is adjusted. After the nut on the surface of the second screw 62 is fed in, the height of the flat plate 63 can be adjusted according to the oblong hole on the surface of the flat plate 63. The height from the bottom of the flat plate 63 to the surface of the conveyor belt 1 is the thickness of the particles after spreading. In use, the material in the hopper 4... ABS granules are discharged from the bottom outlet of the lifting sleeve 61. After being flattened by the flat plate 63, the granules are conveyed to the drying equipment by the conveyor belt 1 with a certain thickness for rapid drying. When material accumulates at the outlet, excess material will be squeezed to the outside of both ends of the flat plate 63, resulting in granule accumulation. This part of the accumulated granules will be effectively cleaned when passing through the scraper 2 and discharged and collected through the drop holes opened on the surface of the conveyor belt 1, thereby ensuring that the granules entering the drying equipment are of uniform thickness and effectively flattened, which is convenient for drying.

[0027] Furthermore, when too many particles accumulate at the discharge port, the accumulated particles compress the folding plate 693, causing the spring 695 to contract under pressure. At this time, the folding plate 693 will contact the contact plate 694, thereby generating a control signal to cause the hydraulic cylinder 66 to contract and push the insert plate 68 into the holder 64, thereby reducing the size of the discharge port and slowing down the discharge. When the particles no longer accumulate, the contact plate 694 and the folding plate 693 separate under the action of the spring 695. At this time, the hydraulic cylinder 66 extends, increasing the size of the discharge port and ensuring the discharge effect.
