A waste plastic masterbatch recycling, drying and screening machine

Abstract

This invention discloses a waste plastic masterbatch recycling, drying, and screening machine, relating to the field of plastic masterbatch recycling technology. It includes a machine body with a screen fixedly installed on one side and a conveyor platform fixedly connected to the bottom of the inner wall. It also includes a material agitation mechanism and a swing drying mechanism. The swing drying mechanism is driven by the material agitation mechanism, which agitates the material above the conveyor platform. The swing drying mechanism increases the uniformity of material drying. By swinging the agitator, the material is turned over, ensuring that all parts are fully exposed to hot air, thus avoiding over-drying of some parts while under-drying others, improving drying uniformity. Simultaneously, the rotating wheel drives the agitator to swing back and forth while agitating the material, further enhancing the turning effect and thus improving the uniformity of material drying.

[0033] The present invention is further described in detail below based on the accompanying drawings and embodiments.

[0034] Embodiments of the present invention

[0035] Please refer to Figures 1 to 7 As shown:

[0036] In order to solve the problems mentioned in the technical solution, the embodiment of the present application provides a waste plastic masterbatch recycling drying and screening machine, including a machine body 1, a sifter 12 is fixedly installed on one side of the machine body 1, a conveying platform 2 is fixedly connected to the bottom of the inner wall of the machine body 1, and also includes: a material shifting mechanism and a swing drying mechanism, the swing drying mechanism is driven by the material shifting mechanism;

[0037] The material moving mechanism is used to move the material above the conveying platform 2;

[0038] The swing drying mechanism is used to increase the uniformity of material drying.

[0039] The material moving mechanism includes a mounting rod 301, which is fixedly connected to the bottom of the inner wall of the machine body 1. Two guide columns 302 are slidably inserted on the top of the mounting rod 301. The top of the guide column 302 is fixedly connected to a connecting seat 303. A driving cylinder 316 is fixedly connected to the bottom of the inner wall of the machine body 1. The output end of the driving cylinder 316 is fixedly connected to the bottom of the connecting seat 303. Two support rods 304 are fixedly connected to one side of the connecting seat 303. A support block 305 is fixedly connected to the bottom of the support rod 304. A rotating shaft 306 is connected to one side of the support block 305. The movable sleeve 306 has a gear 307 fixedly sleeved on the outer surface of the rotating sleeve 306, a rack 308 is fixedly connected to the bottom of the inner wall of the body 1, the gear 307 is meshed with the rack 308, and a sliding rod 309 is slidably inserted at one end of the rotating sleeve 306 away from the gear 307, and a T-shaped slide bar is equidistantly fixedly connected to the outer surface of the sliding rod 309, the T-shaped slide bar is slidably inserted into the rotating sleeve 306, and the sliding rod 309 is fixedly connected to a rotating wheel 310 at one end away from the rotating sleeve 306, and the rotating wheel 310 is rotatably connected to one side of the support rod 304 at one end away from the sliding rod 309.

[0040] The outer surface of the rotating wheel 310 is fixedly connected with a toggle rod 311 at equal intervals, and one end of the toggle rod 311 is set to a multi-finger shape. The outer surface of the sliding rod 309 is fixedly connected with a fixed disk 312, and a protrusion 313 is fixedly connected to one side of the fixed disk 312 at equal intervals. The protrusion 313 is set to a hemispherical shape. A return spring 314 is fixedly connected between the fixed disk 312 and the rotating sleeve 306. The support block 305 is fixedly connected to one side close to the fixed disk 312 with two push posts 315, and one end of the push post 315 close to the protrusion 313 is set to a spherical shape.

[0041] Among them: through the setting of the T-shaped slide bar, the T-shaped structure can increase the contact area with the slideway of the rotating sleeve 306 when the sliding rod 309 slides, thereby improving its bearing capacity and being able to withstand greater weight and pressure. At the same time, it provides a good guiding effect, making the sliding more precise and smooth, reducing errors and friction. At the same time, through the multi-finger setting of the toggle rod 311, it has multiple branches, thereby increasing the angle when turning the material, reducing dead angles, and thus improving the toggle efficiency.

[0042] In the prior art, after the plastic is screened, it is transported to the drying equipment through the conveyor platform 2, so that the plastic is dried in the process of passing through the drying equipment. However, when the plastic material passes through the drying equipment of the drying screening machine, the plastic material is mostly fixed, and the drying head of the drying equipment is also fixed, so that the bottom part of the material is subjected to heat radiation more slowly, which prolongs the drying time and affects the drying efficiency. Compared with the prior art, in the implementation of this embodiment, the sliding rod 309 drives the rotating wheel 310 and the toggle rod 311 to rotate while continuously approaching the material below, and then the material can be turned over by the swing of the toggle rod 311 to ensure that each part can fully contact the hot air, thereby avoiding the situation that some materials are over-dried while other parts are insufficiently dried, and improving the uniformity of drying. The rotating wheel 310 drives the toggle rod 311 to shake back and forth while shifting the material, and the shaking further improves the turning effect of the material, thereby further improving the uniformity of material drying.

[0043] For further examples, please refer to Figures 1 to 7 As shown:

[0044] The swing drying mechanism includes a drying tube 401, which is rotatably connected to the top of the inner wall of the machine body 1, and the bottom end of the drying tube 401 is equidistantly fixedly connected to a drying nozzle 402, and the outer surface of the drying nozzle 402 is fixedly connected to a linkage column 403, and the top of the inner wall of the machine body 1 is slidably connected to a reciprocating rod 404, and the bottom of the reciprocating rod 404 is fixedly connected to two push-pull columns 405, and the top of the connecting seat 303 is rotatably connected to a connecting rod 406, and the top of the connecting rod 406 is rotatably connected to the reciprocating rod 404, and the drying nozzle 402 is set to be conical, and the linkage column 403 is located between the two push-pull columns 405;

[0045] Among them: the tapered setting of the drying nozzle 402 makes the cross section of the drying nozzle 402 gradually increase from top to bottom, thereby expanding the blowing range of the drying gas, and during use, the reciprocating rotation of the drying nozzle can reduce the drying blind area of ​​the material and ensure that the material is heated evenly.

[0046] In the implementation of this embodiment, the push-pull column 405 pushes the linkage column 403 to move, so that the linkage column 403 makes an arc motion and drives the drying tube 401 and the drying nozzle 402 to rotate reciprocatingly. Therefore, through the reciprocating rotation of the drying nozzle 402, the drying blind area of ​​the material can be reduced to ensure that the material is heated evenly.

[0047] Everything in the above example works like this:

[0048] In the initial state: the return spring 314 is in a normal state, and the top of the drying tube 401 is rotatably connected to the output end of the dryer.

[0049] The following is the working process of the material moving mechanism for moving the material above the conveyor platform 2:

[0050] When in use, the dryer is started so that the dryer dries the material below through the drying pipe 401 and the drying nozzle 402. When the material screened by the sifter 12 is transported to the bottom of the support rod 304 through the conveying platform 2, the driving cylinder 316 can be started and under the guidance of the guide column 302, the output end of the driving cylinder 316 can continuously push and pull the connecting seat 303 to slide up and down. When the connecting seat 303 slides up and down, the connecting seat 303 drives the support rod 304 to move up and down, thereby driving the gear 307 to move downward. Because the gear 307 is in a meshing state with the rack 308, during the process of the gear 307 moving downward, the rack 308 is engaged with the gear 307. 08, the gear 307 can be rotated, and then the rotating sleeve 306 can be driven to rotate under the support of the support block 305. Because the outer surface of the sliding rod 309 is slidably connected with the rotating sleeve 306 through the T-shaped sliding strip, when the rotating sleeve 306 rotates, the sliding rod 309 can be driven to rotate at the same time, so that the sliding rod 309 drives the rotating wheel 310 and the toggle rod 311 to rotate while constantly approaching the material below, and then the swing of the toggle rod 311 can turn the material to ensure that each part can fully contact the hot air, thereby avoiding the situation where some materials are over-dried while other parts are not dried sufficiently, and improving the uniformity of drying;

[0051] When the cam 315 is in the state of being moved, the cam 313 is moved back and forth, and the cam 313 is moved back and forth, so that ...

[0052] In addition, by setting the T-shaped slide bar, the T-shaped structure of the sliding rod 309 increases the contact area with the slideway of the rotating sleeve 306 when sliding, thereby improving its load-bearing capacity and being able to withstand greater weight and pressure, while providing a good guiding effect, making the sliding more precise and smooth, reducing errors and friction, and at the same time, through the multi-finger setting of the toggle rod 311, it has multiple branches, thereby increasing the angle when turning the material, reducing dead angles, and thus improving the efficiency of toggling.

[0053] Please refer to the above working process Figures 1 to 7 .

[0054] The following is the working process of the swing drying mechanism to increase the uniformity of material drying:

[0055] Furthermore, when the material moving mechanism is turning the material over, the connecting seat 303 moves up and down, thereby pushing and pulling the lower end of the connecting rod 406, and then under the action of the connecting rod 406, the upper end of the connecting rod 406 pushes and pulls the reciprocating rod 404, so that the reciprocating rod 404 slides back and forth on the top of the inner wall of the body 1. When the reciprocating rod 404 slides back and forth, the reciprocating rod 404 drives the push-pull column 405 to slide back and forth at the same time, so that the push-pull column 405 pushes the linkage column 403 to move, so that the linkage column 403 moves in an arc and drives the drying. The tube 401 and the drying nozzle 402 reciprocate, so that the drying blind area of ​​the material can be reduced through the reciprocating rotation of the drying nozzle 402, ensuring that the material is heated evenly. At the same time, the conical setting of the drying nozzle 402 makes the cross section of the drying nozzle 402 gradually increase from top to bottom, thereby expanding the blowing range of the drying gas. At the same time, the rotation of the drying tube 401 is driven by the driving cylinder 316 in the material shifting mechanism, so that the material shifting work and the rotation work of the drying tube 401 are carried out simultaneously, saving the installation of an additional driving source and improving the efficiency.
