Description

Technical Field

[0001] This utility model belongs to the field of plastic granule processing technology, specifically relating to a rapid cooling device for continuous processing of plastic granules. Background Technology

[0002] Plastic granules refer to granular plastics, generally classified into more than two hundred types, with further subdivisions reaching thousands. Common types of plastic granules include general-purpose plastics, engineering plastics, and specialty plastics. Plastic granules can be made into many different objects. The production and processing of plastic granules involves multiple steps such as heating, extrusion granulation, and cooling. Cooling the extruded granules with cold water allows for rapid molding.

[0003] Patent CN215882529U discloses "A rapid cooling mechanism for plastic granule production, relating to the field of plastic granule cooling technology. The mechanism includes a mounting platform, a cooling box, and a water tank. This invention cools the plastic granules using the cooling box and water tank. Water cooling rapidly improves the cooling efficiency of the plastic granules. Furthermore, the mixing plate, second telescopic cylinder, and rotary cylinder agitate the inside of the water tank, accelerating heat dissipation and reducing cooling time, thereby further improving the cooling efficiency of the plastic granules."

[0004] Although the existing technology can quickly cool the extruded plastic granules, when the lifting plate moves upward to discharge the cooled plastic granules, the feeding needs to be paused to avoid mixing the incoming uncooled plastic granules with the cooled plastic granules. However, the extrusion production of plastic granules by extrusion equipment such as extruders is continuous. The cooling and processing of plastic granules by the cooling equipment after the feeding is paused is not continuous enough, which will reduce the production efficiency of plastic granules. Therefore, it needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide a rapid cooling device for continuous processing of plastic granules in order to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A rapid cooling device for continuous processing of plastic granules includes a cooling cylinder with water at the bottom, a feeding and storage mechanism installed at the top of the cooling cylinder for temporarily storing plastic granules, a discharging mechanism installed at the bottom of the cooling cylinder for discharging the cooled plastic granules by rotation, and a drive mechanism installed at the bottom of the cooling cylinder for driving the discharging mechanism to rise and fall. The feeding and storage mechanism includes a feeding hopper fixedly installed at the top of the cooling cylinder, a circular plate rotatably installed in the bottom end of the feeding hopper, and a first motor fixedly installed on the outside of the bottom end of the feeding hopper for driving the circular plate to rotate.

[0008] A concentrating hopper is fixedly provided on the bottom of the outer side of the cooling cylinder. A fan blade is provided on the outer side of the discharge mechanism to send air into the concentrating hopper as the discharge mechanism rotates. A blower pipe is fixedly provided between the top of the concentrating hopper and the bottom of the feeding hopper to cool down the plastic particles temporarily stored on the top of the circular plate.

[0009] As a further optimization of this utility model, a drain pipe is fixedly provided at the bottom of the inner side of the cooling cylinder, and a valve is provided inside the drain pipe.

[0010] As a further optimization of this utility model, a second motor is provided at the bottom of the cooling cylinder, and the discharge mechanism includes a rotating rod fixedly disposed at the top of the output end of the second motor and coaxial with the cooling cylinder, and a mesh plate fixedly disposed at the top of the rotating rod and movably connected in the matching cooling cylinder, and the fan blades are fixedly disposed on the outer wall of the bottom end of the rotating rod.

[0011] As a further optimization of this utility model, an inclined discharge hopper is fixedly provided in the discharge port opened on one side of the cooling cylinder, and a guide plate is fixedly provided in the middle of the inner side of the cooling cylinder, which abuts against the top of the mesh plate and is used to guide the plastic particles on the rotated mesh plate into the discharge hopper.

[0012] As a further optimization of this utility model, the bottom of the mesh plate is fixedly provided with several agitation plates for agitating the water stored at the bottom of the cooling cylinder.

[0013] As a further optimization of this utility model, the drive mechanism includes an electric push rod fixedly disposed at the bottom of the outer side of the cooling cylinder, and a connecting plate fixedly disposed between the bottom end of the electric push rod and the bottom of the second motor.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. The inner circular plate of the feed hopper can temporarily store the incoming plastic granules, so that the feeding will not be interrupted during the discharge process, thus ensuring the continuity of plastic granule production and improving the production efficiency. After the discharge mechanism rotates, it will drive the fan blades to rotate and generate wind. The wind is gathered by the air hopper and discharged through the air pipe to cool the plastic granules temporarily stored on the top of the circular plate. After discharge, the plastic granules can fall into the water at the bottom of the cooling cylinder by flipping the circular plate for rapid cooling. It is convenient and practical.

[0016] 2. By lifting the discharge mechanism through the drive mechanism, the inner screen plate of the discharge mechanism can be moved up and separated from the water at the bottom of the cooling cylinder. The discharge mechanism is driven to rotate by the second motor, so that the cooled plastic particles on the top of the screen plate can move to the edge of the screen plate due to centrifugal force when the screen plate rotates. Under the guidance and obstruction of the guide plate, they are quickly discharged from the discharge hopper, thus quickly discharging the cooled plastic particles. After the screen plate rotates in the water at the bottom of the cooling cylinder, it will use the stirring plate to stir the water, so that the water can contact the plastic particles more evenly, thereby improving the cooling effect of the plastic particles.

[0021] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example

[0023] like Figure 1-3 As shown, a rapid cooling device for continuous processing of plastic granules includes a cooling cylinder 1 with water at the bottom, a feeding temporary storage mechanism, a discharging mechanism, and a driving mechanism. The feeding temporary storage mechanism is installed at the top of the cooling cylinder 1 and is used to temporarily store the plastic granules. The discharging mechanism is installed at the bottom of the cooling cylinder 1 and is used to discharge the cooled plastic granules by rotation. The driving mechanism is installed at the bottom of the cooling cylinder 1 and is used to drive the discharging mechanism to rise and fall. A drain pipe 11 is fixedly provided at the bottom inside the cooling cylinder 1. A valve is provided inside the drain pipe 11. Cooling water is contained at the bottom inside the cooling cylinder 1.

[0024] Water can be added to the cooling cylinder 1 through the feeding temporary storage mechanism, or the water in the cooling cylinder 1 can be drained through the drain pipe 11 to replace the water in the cooling cylinder 1. The valve in the drain pipe 11 can be switched to control the flow of water in the drain pipe 11. An observation window can be provided on one side of the cooling cylinder 1 for staff to observe the internal condition of the cooling cylinder 1.

[0025] like Figure 1-2 As shown, the feeding temporary storage mechanism includes a feeding hopper 2 fixedly installed at the top of the cooling cylinder 1, a circular plate 21 rotatably installed in the bottom end of the feeding hopper 2, and a first motor 22 fixedly installed on the outside of the bottom end of the feeding hopper 2 to drive the circular plate 21 to rotate. The extruder can feed material into the cooling cylinder 1 through the feeding hopper 2. When the discharge mechanism discharges material, the circular plate 21 can block the bottom end of the feeding hopper 2, so that the feeding and discharge of plastic particles in the device will not affect each other, so that the device will not pause feeding when discharging, thus ensuring the continuity of plastic particle production and processing.

[0026] The first motor 22 can be a servo motor. After the first motor 22 runs, it will drive the circular plate 21 to rotate and flip the circular plate 21. After the material is discharged, the plastic particles can fall into the water at the bottom of the cooling cylinder 1 by flipping the circular plate 21, so as to quickly cool the plastic particles.

[0027] like Figure 2-3 As shown, a concentrating air hopper 5 is fixedly provided at the bottom of the outer side of the cooling cylinder 1. A fan blade 51 is provided on the outer side of the discharge mechanism for blowing air into the concentrating air hopper 5 as the discharge mechanism rotates. A blowing pipe 52 is fixed between the top of the concentrating air hopper 5 and the bottom of the feed hopper 2 for blowing air to cool down the plastic particles temporarily stored on the top of the circular plate 21. After the discharge mechanism rotates, it will drive the fan blade 51 to rotate and generate wind. The wind will be concentrated by the concentrating air hopper 5 and discharged through the blowing pipe 52 to blow air to cool down and initially cool the plastic particles temporarily stored on the top of the circular plate 21.

[0028] like Figure 2-3 As shown, a second motor 3 is provided at the bottom of the cooling cylinder 1. The discharge mechanism includes a rotating rod 31 fixedly installed at the top of the output end of the second motor 3 and coaxial with the cooling cylinder 1, and a mesh plate 32 fixedly installed at the top of the rotating rod 31 and movably connected to the cooling cylinder 1. The fan blade 51 is fixedly installed on the outer wall of the bottom end of the rotating rod 31. After the second motor 3 runs, it will drive the rotating rod 31 to drive the mesh plate 32 to rotate at high speed. After the rotating rod 31 rotates, it will drive the fan blade 51 to rotate and generate wind. The rotating rod 31 is rotatably connected to the cooling cylinder 1, and a sealing element can be provided between the rotating rod 31 and the cooling cylinder 1.

[0029] like Figure 2-3As shown, an inclined discharge hopper 34 is fixedly installed in the discharge port on one side of the cooling cylinder 1. A guide plate 35 is fixedly installed in the middle of the inner side of the cooling cylinder 1, which abuts against the top of the screen plate 32 and is used to guide the plastic particles on the rotated screen plate 32 into the discharge hopper 34. When the screen plate 32 is immersed in the water in the cooling cylinder 1, the plastic particles fed in by the feed hopper 2 will fall into the water in the cooling cylinder 1. At this time, the screen plate 32 will be located below the plastic particles immersed in the water.

[0030] When the screen plate 32 moves upward and abuts against the bottom of the guide inclined plate 35, the screen plate 32 will scoop up and lift the plastic particles cooled in the water at the bottom of the cooling cylinder 1. After the second motor 3 runs, it will drive the rotating rod 31 to drive the screen plate 32 to rotate at high speed. At this time, the plastic particles cooled on the top of the screen plate 32 will move to the edge of the screen plate 32 due to centrifugal force when the screen plate 32 rotates, and will be quickly discharged from the discharge hopper 34 under the guidance and obstruction of the fixed guide inclined plate 35, thereby quickly discharging the cooled plastic particles.

[0031] like Figure 2-3 As shown, the drive mechanism includes an electric push rod 4 fixedly installed at the bottom of the outer side of the cooling cylinder 1, and a connecting plate 41 fixedly installed between the bottom of the electric push rod 4 and the bottom of the second motor 3. The connecting plate 41 can connect the electric push rod 4 and the second motor 3. After the electric push rod 4 extends and retracts, it will drive the second motor 3 and the discharge mechanism and other structures to move up and down.

[0032] like Figure 2 As shown, the bottom of the mesh plate 32 is fixed with several agitator plates 33 for stirring the water at the bottom of the cooling cylinder 1. When the mesh plate 32 is immersed in the water in the cooling cylinder 1, the agitator plates 33 and other components can be rotated by the drive of the second motor 3. The rotated agitator plates 33 will stir the water at the bottom of the cooling cylinder 1, so that the water can come into more uniform contact with the plastic particles, thereby improving the cooling effect on the plastic particles.

[0033] It should be noted that, in use, the rapid cooling device for continuous processing of plastic granules allows external extrusion equipment such as extruders to feed plastic granules into the cooling cylinder 1 through the feed hopper 2, causing the plastic granules to fall into the water stored at the bottom of the cooling cylinder 1 for rapid cooling.

[0034] Simultaneously, after the electric push rod 4 extends and retracts, it will drive the second motor 3 and the discharge mechanism to move up and down. When the mesh plate 32 is immersed in the water in the cooling cylinder 1 after it moves down, the second motor 3 can drive the rotating rod 31, the mesh plate 32 and the stirring plate 33 to rotate. The rotating stirring plate 33 will stir the water at the bottom of the cooling cylinder 1, so that the water can contact the plastic particles more evenly, thereby improving the cooling effect on the plastic particles.

[0035] During discharge, the screen plate 32 can be controlled to move upward and abut against the bottom of the guide inclined plate 35. The screen plate 32 will scoop up and lift the plastic particles cooled in the water at the bottom of the cooling cylinder 1. After the second motor 3 runs, it will drive the rotating rod 31 to drive the screen plate 32 to rotate at high speed. At this time, the plastic particles cooled at the top of the screen plate 32 will move to the edge of the screen plate 32 due to centrifugal force when the screen plate 32 rotates. Under the guidance and obstruction of the fixed guide inclined plate 35, they will be quickly discharged from the discharge hopper 34, thereby quickly discharging the cooled plastic particles.

[0036] Simultaneously, the first motor 22 can be controlled to drive the circular plate 21 to rotate, so that the rotated circular plate 21 can block the bottom of the feed hopper 2, so that the incoming plastic granules can be temporarily stored through the circular plate 21 inside the feed hopper 2. This prevents the feeding and discharging of plastic granules in the device from affecting each other, so that the device will not pause feeding during discharging, thus ensuring the continuity of plastic granule production and processing. After the rotating rod 31 and other discharging mechanisms rotate, they will drive the fan blades 51 to rotate and generate wind. The wind is gathered by the wind concentrator 5 and discharged through the blower pipe 52 to blow and cool the plastic granules temporarily stored on the top of the circular plate 21. After discharging, by rotating and flipping the circular plate 21, the plastic granules can fall into the water at the bottom of the cooling cylinder 1 for rapid cooling, thus enabling continuous processing of plastic granules.

[0037] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
