Description

Technical Field

[0001] The utility model relates to the technical field of plastic particle production, in particular to a drying device for modified plastic production. Background Art

[0002] Plastic is a very common material in industrial production and daily life. At present, various plastic products are usually produced from plastic particles through extrusion or injection molding. During the storage of plastic particles, affected by the environment and storage conditions, the external moisture makes the plastic particles easy to get damp, thus affecting the quality of the product. Therefore, it is necessary to use special plastic particle drying equipment to dry the plastic particles before use to remove moisture to ensure product quality.

DETAILED DESCRIPTION

The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0026] like Figures 1 to 6 As shown, the utility model is a drying device for modified plastic production, comprising: a box body 1, a feed pipe plugged and installed on the top of the box body 1, a drying box 20 rotatably installed in the inner cavity of the box body 1 for storing plastic particles, a guide plate 21 fixedly installed at the bottom of the inner cavity of the drying box 20, a discharge pipe plugged on the side wall of the drying box 20 and the guide plate 21, a solenoid valve fixedly installed on the discharge pipe, a heating plate 23 for drying the plastic particles in the inner cavity of the drying box 20, a stirring mechanism for stirring the plastic particles in the inner cavity of the drying box 20 during drying, a rotating mechanism for driving the drying box 20 to rotate during drying, and a driving member for synchronously driving the stirring mechanism and the rotating mechanism to operate;

[0027] An appropriate amount of plastic particles are added to the inner cavity of the drying box 20 through the feed pipe, and the heating plate 23 is started. The plastic particles can be heated and dried by the heating plate 23. Since the heating plates 23 are provided with multiple groups, which are respectively fixedly installed on the inner cavity side walls of the box body 1, the plastic particles in the inner cavity of the drying box 20 can be dried in multiple directions, thereby improving the drying efficiency. At the same time, the driving member is started to synchronously drive the stirring mechanism and the rotating mechanism to operate. The plastic particles in the inner cavity of the drying box 20 are stirred by the stirring mechanism, thereby avoiding the accumulation of plastic particles, so that the plastic particles are heated evenly, thereby the plastic particles can be dried evenly, and the drying quality is improved. The drying box 20 is driven to rotate by the rotating mechanism, thereby driving the plastic particles to rotate as a whole. The movement further makes the plastic particles evenly heated and dried, further improves the drying quality, speeds up the drying efficiency, and solves the problems that the existing plastic particle raw materials are prone to pile up after cleaning. The raw materials stacked on each other during the drying process are prone to incomplete drying. The plastic particles inside are difficult to heat, and the plastic particles outside are overheated, resulting in uneven heating of the plastic particles, which reduces the quality of the finished product and is not conducive to the subsequent storage and processing of the raw materials. In addition, the existing drying device cannot stir and dry the plastic particles, and the drying rate is low, which affects the production efficiency and brings certain adverse effects to people's use process. After the drying is completed, the solenoid valve is opened by starting the plastic particles to be discharged through the discharge pipe.

[0028] It is supplemented here that the top of the guide plate 21 is arranged on an arc-shaped groove, and the plastic particles can slide along the arc surface of the arc-shaped groove toward the discharge pipe, thereby improving the discharge efficiency.

[0029] The driving member is preferably a motor 22; the drying box 20 is a mesh structure, so that the plastic particles are heated well.

[0030] The stirring mechanism includes: a rotating shaft rotatably mounted on the top of the box body 1, the top of the rotating shaft is fixedly mounted on the power output end of the motor 22, a movable tube 7 sleeved on the outer edge of the long shaft, a limit groove is provided on the inner wall of the movable tube 7, a limit strip 10 is fixedly mounted on the outer side of the rotating shaft, the limit strip 10 is slidably mounted in the inner cavity of the limit groove, a spiral blade 24 is fixedly sleeved on the outer edge of the movable tube 7, a scraper 8 is fixedly mounted on the bottom end of the movable tube 7, a stirring plate 9 is fixedly mounted on the inner side of the scraper 8, and a linkage component that drives the scraper 8 to rotate and rise and fall; the linkage component includes : A cylinder 2 is fixedly sleeved on the outer edge of the rotating shaft, a ring 3 is sleeved on the outer edge of the cylinder 2, a rolling member is rotatably installed on the inner side of the ring 3, a guide groove is opened on the outer edge of the cylinder 2, the rolling member is slidably installed in the inner cavity of the guide groove, and a limiting unit is used to limit the ring 3. The limiting unit includes: a limiting tube 4 inserted on the side wall of the ring 3, and a limiting rod 5 inserted in the inner cavity of the limiting tube 4; a circular plate 6 is fixedly installed on the bottom end of the limiting tube 4, a movable tube 7 is rotatably installed on the side wall of the circular plate 6, and the top of the limiting rod 5 is fixedly installed on the top of the inner cavity of the box body 1.

[0031] It should be noted here that the rolling element is preferably: a bull's eye ball; the guide groove is composed of two U-shaped grooves with opposite directions and inner cavities interpenetrating each other, and the guide groove is a closed-loop design.

[0032] When the motor 22 is started, the shaft can be driven to rotate, and the cylinder 2 and the limit bar 10 can be driven to rotate through the shaft. When 10 rotates, the limit bar 10 slides in the inner cavity of the limit groove on the inner wall of the movable tube 7, thereby driving the movable tube 7 to rotate. The rotation of the movable tube 7 can drive the scraper 8, the stirring plate 9, and the spiral blade 24 to rotate. The rotation of the spiral blade 24 can flip the plastic particles from bottom to top, so that the plastic particles at the top of the drying box 20 and the plastic particles at the bottom are mixed, ensuring that the plastic particles are evenly mixed in the vertical direction. The rotation of the scraper 8 can flip the plastic particles attached to the inner wall of the drying box 20. The particles are scraped off, so that the plastic particles are fully mixed. The stirring plate 9 rotates with the rotation of the scraper 8, and the plastic particles turned up by the spiral blade 24 can be scattered and stirred. Through the cooperation of the scraper 8 and the stirring plate 9, the plastic particles can be stirred in the horizontal direction, so that the plastic particles are evenly mixed in the horizontal direction. Through the cooperation of the scraper 8, the stirring plate 9 and the spiral blade 24, the plastic particles can be turned and mixed synchronously, and the plastic particles can be mixed horizontally and vertically, ensuring the uniformity of the plastic particles, thereby ensuring the uniform drying of the plastic particles and improving the drying quality.

[0033] When the cylinder 2 rotates, since the rolling element is slidably installed in the inner cavity of the guide groove, under the limiting effect of the guide groove, the rolling element slides along the inner cavity of the guide groove, thereby driving the ring 3 to move, and the limiting effect of the limiting tube 4 and the limiting rod 5 on the ring 3 makes the ring 3 move up and down reciprocatingly, and the limiting tube 4 is driven to move up and down by the ring 3, and the circular plate 6 is driven to move up and down by the limiting tube 4, and the movable tube 7 is driven to move up and down by the circular plate 6, and then the scraper 8, the stirring plate 9, and the spiral blade 24 can be driven to move up and down reciprocatingly, thereby expanding the stirring range of the plastic particles in the inner cavity of the drying box 20, avoiding the occurrence of stirring dead corners, and making the plastic particles in the inner cavity of the drying box 20 mixed uniformly as a whole, further ensuring the uniform drying of the plastic particles and improving the drying quality.

[0034] By rotating the scraper 8, the stirring plate 9 and the spiral blade 24 and reciprocating up and down, the plastic particles in the inner cavity of the drying box 20 can be fully mixed, so that the plastic particles in the inner cavity of the drying box 20 are mixed uniformly as a whole, ensuring uniform drying of the plastic particles and improving the drying quality.

[0035] The rotating mechanism includes: a driving gear 11 fixedly sleeved on the outer edge of the rotating shaft, a driven gear 12 meshingly installed on one side of the driving gear 11, a rotating rod inserted on the side wall of the driven gear 12, a driving bevel gear 13 fixedly sleeved on the outer edge of the rotating shaft, a driven bevel gear 14 meshingly installed on one side of the driving bevel gear 13, a linkage shaft fixedly installed on one side of the driven bevel gear 14, a driving pulley 15 fixedly installed on the other end of the linkage shaft, a transmission bevel gear 19 fixedly sleeved on the outer edge of the drying box 20, a linkage bevel gear 18 meshingly installed on one side of the transmission bevel gear 19, a transmission shaft fixedly installed on one side of the linkage bevel gear 18, a driven pulley 17 fixedly installed on one end of the transmission shaft, and a linkage belt 16 installed between the driving pulley 15 and the driven pulley 17.

[0036] When the shaft rotates, the driving gear 11 can be driven to rotate, and the driven gear 12 can be driven to rotate through the driving gear 11, so that the driving bevel gear 13 can be driven to rotate, and the driven bevel gear 14 can be driven to rotate through the driving bevel gear 13, so that the driving pulley 15 can be driven to rotate, and the linkage belt 16 of the driving pulley 15 can be rotated, and the driven pulley 17 can be driven to rotate through the linkage belt 16, so that the linked bevel gear 18 can be driven to rotate, and the transmission bevel gear 19 can be driven to rotate through the transmission bevel gear 19, so that the plastic particles can be driven to rotate as a whole, so that the plastic particles are further evenly heated and dried, and the drying quality is further improved, and the drying efficiency is accelerated.

[0037] By rotating the scraper 8, the stirring plate 9 and the spiral blade 24 and reciprocatingly moving up and down, and synchronously rotating the drying box 20, the plastic particles in the inner cavity of the drying box 20 can be fully mixed, so that the plastic particles in the inner cavity of the drying box 20 are mixed uniformly as a whole, thereby ensuring uniform drying of the plastic particles and improving the drying quality.

[0038] Working principle: When in use, add an appropriate amount of plastic particles into the inner cavity of the drying box 20 through the feed pipe, start the heating plate 23, and heat and dry the plastic particles through the heating plate 23. At the same time, start the driving member to synchronously drive the stirring mechanism and the rotating mechanism to operate. The plastic particles in the inner cavity of the drying box 20 are stirred by the stirring mechanism to avoid the accumulation of plastic particles, so that the plastic particles are heated evenly, so that the plastic particles can be dried evenly, and the drying quality is improved. The drying box 20 is driven to rotate by the rotating mechanism, so that the plastic particles can be driven to rotate as a whole, and the plastic particles are further heated and dried evenly, and the drying quality is further improved. After drying is completed, the solenoid valve is opened by starting the plastic particles to be discharged through the discharge pipe.
