Description

Technical Field

[0001] This utility model relates to the field of plastic production technology, and in particular to a drying device for plastic raw materials. Background Technology

[0002] Plastic raw materials are high-molecular polymers produced through chemical synthesis or modification from petroleum, natural gas, or biomass. They possess plasticity and can be processed into various products through injection molding, extrusion, blow molding, and other processes, finding wide application in packaging, construction, automotive, and electronics industries. Depending on performance requirements, fillers, plasticizers, or flame retardants can be added for modification. In the plastics processing industry, moisture content in plastic raw materials can easily lead to defects such as bubbles and silver streaks in finished products, severely affecting product performance and quality. As the industry develops towards high-precision and sophisticated technologies, the requirements for the quality of raw material drying are becoming increasingly stringent.

[0003] However, most existing plastic raw material drying devices use static drying. The static nature of the raw materials leads to slow moisture dissipation and long drying time. Furthermore, the accumulation of particles causes uneven drying, affecting the stability of product quality and increasing the scrap rate. After drying, the raw materials are also prone to sticking together and clumping, making discharge difficult and slow, which affects the continuity of production. Utility Model Content

[0030] Example 1:

[0031] Reference Figures 1 to 7 This is the first embodiment of the present invention, which provides a drying device for plastic raw materials, including a base 100. The base 100 is configured to support the installation of a drying mechanism 200. The drying mechanism 200 is mounted on the base 100. By using the drying mechanism 200 to tumble the raw material, the plastic raw material is dried, which facilitates faster drying and convenient discharge. A vibration mechanism 300 is mounted on the drying mechanism 200. By using the vibration mechanism 300, vibration is performed synchronously during the tumbling process of the raw material, which, in conjunction with the drying mechanism 200, facilitates the drying of the raw material and also facilitates the discharge of the raw material. The drying mechanism 200 includes a support 201. By setting the drying mechanism 200, the plastic raw material is dried by tumbling the raw material, which is conducive to accelerating the drying of the raw material and facilitating material discharge. The support 201 is fixedly installed on the base 100. The support 201 is U-shaped and is set to support the rotation of the first mounting ring 206. The inner wall of the support 201 is rotatably connected to the first mounting ring 206. The first mounting ring 206 is set to support the rotation of the drying box 207. The inner wall of the first mounting ring 206 is rotatably connected to the drying box 207. The drying box 207 is set to store the plastic raw material.

[0032] The vibration mechanism 300 includes a mounting frame 302. By providing the vibration mechanism 300, vibration will occur synchronously during the turning of the raw material. This, in conjunction with the drying mechanism 200, facilitates the drying of the raw material and also facilitates its discharge. The mounting frame 302 is fixedly mounted on the top of the first mounting ring 206. The mounting frame 302 is L-shaped and is used to support the sliding of the slide rod 301. The slide rod 301 is slidably mounted on the inner wall of the mounting frame 302. The slide rod 301 consists of a square rod and a disc. The square rod is slidably mounted on the mounting frame 302, and the disc is fixedly mounted on the slide rod 301. A receiving frame 306 is fixedly mounted on the bottom end of the slide rod 301. The receiving frame 306 is U-shaped and is used to support the rotation of the roller 305. The roller 305 is rotatably connected to the inner wall of the receiving frame 306 and is used to strike the drying chamber 207.

[0033] Example 2:

[0034] Reference Figures 1 to 7 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, a first hinge seat 214 is fixedly installed on the base 100, and a cylinder 215 is rotatably connected to the inner wall of the first hinge seat 214.

[0036] The base 100 is set to support the installation of the first hinge seat 214. The first hinge seat 214 is set to support the rotation of the cylinder 215. The cylinder 215 is set to drive the drying chamber 207 to deflect around the support 201 until the drying chamber 207 deflects to a suitable tilt angle, which, in conjunction with the vibration mechanism 300, facilitates the discharge of plastic raw materials.

[0037] Specifically, a second mounting ring 205 is rotatably connected to the surface of the drying oven 207. The second mounting ring 205 is circular in shape, and a second hinge seat 216 is fixedly installed at the bottom end of the second mounting ring 205. The piston rod end of the cylinder 215 is rotatably connected to the inner wall of the second hinge seat 216.

[0038] The drying chamber 207 is designed to support the installation of the second mounting ring 205, which is circular in shape. The second mounting ring 205 is also designed to support the installation of the second hinge seat 216. The second hinge seat 216 is designed to support the installation of the piston rod of the cylinder 215. The cylinder 215 is designed to drive the drying chamber 207 to rotate around the support 201 until the drying chamber 207 is rotated to a suitable tilt angle, which, in conjunction with the vibration mechanism 300, facilitates the discharge of plastic raw materials.

[0039] Specifically, the inner wall of the drying oven 207 is fixedly installed with baffles 213, which are strip-shaped and there are eight baffles 213.

[0040] The drying chamber 207 is designed to store plastic raw materials, and the baffle 213 is designed to flip the plastic raw materials when the drying chamber 207 rotates, so as to dry the raw materials quickly.

[0041] Specifically, a motor 212 is fixedly mounted on the bottom end of the first mounting ring 206, and a first transmission wheel 202 is fixedly mounted on the shaft end of the motor 212.

[0042] The motor 212 is used to drive the first transmission wheel 202 to rotate. The first transmission wheel 202, together with the track 211, is used to drive the second transmission wheel 217 to rotate, thereby achieving the purpose of driving the drying box 207 to rotate, which is beneficial for turning the plastic raw materials.

[0043] Specifically, a second transmission wheel 217 is fixedly installed at the end of the drying box 207, and the second transmission wheel 217 is meshed with the first transmission wheel 202 by a track 211.

[0044] The second transmission wheel 217 is set up to drive the drying box 207 to rotate under the drive of the first transmission wheel 202 and the track 211. When the drying box 207 rotates, it works with the baffle 213 to facilitate the tumbling of the plastic raw materials, which helps to improve the drying efficiency.

[0045] Example 3:

[0046] Reference Figures 1 to 7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0047] Specifically, one end of the drying oven 207 is threadedly connected to a cover 204, and a first conduit 208 is fixedly installed at the axis of the cover 204. An air outlet pipe 203 is rotatably connected to the inner wall of the first conduit 208.

[0048] The lid 204 is designed to open the drying chamber 207 to allow for the loading and unloading of plastic raw materials. The first conduit 208 is designed to support the installation of the exhaust pipe 203. The exhaust pipe 203 is used for air discharge and also facilitates connection to a filter mechanism to filter the gas discharged from the drying chamber 207.

[0049] Specifically, a second conduit 210 is fixedly installed at one end of the drying oven 207, and an air inlet pipe 209 is rotatably connected to the inner wall of the second conduit 210. Screens are installed at the ends of the first conduit 208 and the second conduit 210.

[0050] The second conduit 210 is used to receive the air inlet pipe 209. The air inlet pipe 209 is used to connect to the hot air blower so that hot air can be introduced into the drying chamber 207. By setting a screen, plastic raw materials are prevented from entering the first conduit 208 and the second conduit 210.

[0051] Specifically, the mounting bracket 302 is L-shaped, the receiving bracket 306 is arched, and a spring 304 is fixedly installed on the mounting bracket 302. One end of the spring 304 is fixedly connected to the slide rod 301.

[0052] The mounting bracket 302 is designed to support the mounting of the spring 304. The spring 304 is designed to apply force to the slide bar 301 so that the roller 305 is in close contact with the surface of the drying oven 207.

[0053] Specifically, four protrusions 303 are fixedly installed on the drying oven 207. The cross-sectional shape of the protrusions 303 is a right triangle.

[0054] The protrusion 303 is designed so that when the drying chamber 207 rotates, it will drive the protrusion 303 to pass through the roller 305 so that the roller 305 can be lifted. When the protrusion 303 leaves the roller 305, the roller 305 will strike the drying chamber 207 under the action of the spring 304, thereby achieving vibration of the drying chamber 207, which is beneficial to the drying of plastic raw materials and also facilitates material discharge.

[0055] In use, open the lid 204, then put the plastic raw material into the drying chamber 207, and put the lid 204 back in place. Then connect the air outlet pipe 203 to the filter mechanism, connect the air inlet pipe 209 to the hot air blower, and start the hot air blower and motor 212. The hot air blower will deliver hot air into the drying chamber 207 through the rear air inlet pipe 209, while the motor 212 will drive the first transmission wheel 202 to rotate. When the first transmission wheel 202 rotates, it will drive the second transmission wheel 217 to rotate through the track 211. When the second transmission wheel 217 rotates, it will drive the drying chamber 207 to rotate along the inner wall of the first mounting ring 206. When the drying chamber 207 rotates, it will cause the plastic raw material to turn over through the baffle 213. Combined with the blowing action of the hot air blower, it helps to accelerate the drying of the plastic raw material.

[0056] Furthermore, during the rotation of the drying chamber 207, the drying chamber 207 will drive the protrusion 303 to perform circumferential motion. When the protrusion 303 contacts the roller 305, it will drive the roller 305 away from the surface of the drying chamber 207. Until the protrusion 303 leaves the roller 305, the roller 305 will once again adhere to the surface of the drying chamber 207 under the action of the spring 304, achieving the purpose of knocking, thereby realizing intermittent vibration of the drying chamber 207, which is beneficial to the drying of plastic raw materials.

[0057] When drying is complete and material needs to be discharged, first turn off the motor 212 and open the box cover 204. Then, the cylinder 215 drives the drying box 207 to deflect around the support 201 until the drying box 207 deflects to a suitable tilt angle. Then, start the motor 212. Driven by the motor 212, the drying box 207 will rotate and continuously tap with the roller 305 to facilitate the discharge of raw materials.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
