Description

Technical Field

[0001] The utility model belongs to the technical field of sheet material processing, and particularly relates to a raw material drying device for polyethylene sheet extrusion molding. Background Technique

[0002] In plastic extrusion molding equipment, the plastic extruder is usually called the main machine, and the subsequent plastic extrusion molding machine supporting it is called the auxiliary machine. After more than 100 years of development, the plastic extruder has evolved from the original single screw to various models such as double screw, multi screw, and even screwless; the plastic extruder belongs to one of the types of plastic machinery and originated in the 18th century; according to the direction of the material flow at the die head and the included angle between the screw center line, the die head can be divided into a right-angle die head and an inclined-angle die head, etc.:

[0003] The main raw material of the polyethylene sheet is polyethylene resin, which is a high molecular polymer formed by the polymerization of ethylene monomers under certain conditions. Before producing the polyethylene sheet, it is necessary to dry the raw materials to improve the production quality:

[0004] When the existing equipment is in use, since raw materials such as plastic particles will agglomerate in a humid environment, if they are not vibrated and crushed during the drying process to restore them to a small size, it may lead to low-quality finished products produced by the raw materials in the subsequent equipment. Therefore, we have proposed a raw material drying device for polyethylene sheet extrusion molding. Content of the Utility Model

[0005] The purpose of the utility model is to provide a raw material drying device for polyethylene sheet extrusion molding. Through the sieving mechanism and the stirring mechanism, it solves the problem that when the existing equipment is in use, since raw materials such as plastic particles will agglomerate in a humid environment, if they are not vibrated and crushed during the drying process to restore them to a small size, it may lead to low-quality finished products produced by the raw materials in the subsequent equipment.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a raw material drying device for polyethylene sheet extrusion molding, including a drying cylinder. The outer wall of the drying cylinder is fixedly connected with a discharge pipe, and the inner wall of the drying cylinder is fixedly connected with a partition cylinder. A sieving mechanism is arranged on the outer wall of the partition cylinder;

[0008] The sieving mechanism includes a sliding rod sleeve, the outer wall of which is fixedly connected to the inner wall of the separator cylinder. The inner wall of the sliding rod sleeve has several limiting grooves. A rotating rod is rotatably connected to the inner wall of the sliding rod sleeve. An arc-shaped groove is formed on the inner wall of the rotating rod. A sliding rod is slidably connected to the inner wall of the arc-shaped groove. The outer wall of the sliding rod is slidably connected to the inner wall of the limiting groove. A sieve plate is fixedly connected to the top outer wall of the sliding rod. The outer wall of the sieve plate is slidably connected to the inner wall of the separator cylinder. A motor is fixedly connected to the inner wall of the drying cylinder. Several limiting shafts are slidably connected to the bottom outer wall of the separator cylinder. The outer wall of the limiting shaft on the left side is fixedly connected to the bottom output of the motor.

[0009] Furthermore, the outer wall of the limiting shaft located on the right side is rotatably connected to the inner wall of the drying cylinder. A pulley is fixedly connected to the outer wall of the limiting shaft near the separator cylinder. A belt is drivenly connected to the outer wall of the pulley. A half gear is fixedly connected to the outer wall of the limiting shaft near the separator cylinder. A gear is fixedly connected to the outer wall of the rotating rod near the half gear. The outer wall of the gear meshes with the outer wall of the half gear. A stirring mechanism is provided on the inner wall of the drying cylinder.

[0010] Furthermore, the stirring mechanism includes a limiting rod, the outer wall of which is fixedly connected to the outer wall of the sliding rod.

[0011] Furthermore, a number of stirring rods are fixedly connected to the outer wall of the limiting rod, and a number of support rods are fixedly connected to the outer wall of the limiting rod.

[0012] Furthermore, a protective cover is fixedly connected to the outer wall of the support rod, and the outer wall of the protective cover is rotatably connected to the outer wall of the slide rod sleeve.

[0013] Furthermore, the inner wall of the protective cover is rotatably connected to several rotating shafts, and a limit rod is fixedly connected to the outer wall of the rotating shaft at the end away from the protective cover.

[0014] Furthermore, a plurality of stirring rods are fixedly connected to the outer wall of the limiting rod 2, and a crown gear is fixedly connected to the outer wall of the end of the rotating shaft away from the stirring rods 2.

[0015] Furthermore, a second gear is fixedly connected to the outer wall of the sliding sleeve near the crown gear, and the outer wall of the second gear meshes with the inner wall of the crown gear. Several heating rods are fixedly connected to the inner wall of the drying cylinder.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model features an arc-shaped sliding groove on the rotating rod. When the equipment is needed, the motor is started, and then raw materials such as plastic granules are poured into the separator. Since the holes in the separator are small, the plastic granules will not pass through the separator. The heating rod and motor are started, and the heat generated by the heating rod passes through the holes in the separator to dry the raw materials. The rotation of the motor can drive the limit shaft on the motor to rotate, causing the pulley near the motor to rotate. This achieves the simultaneous drying of raw materials such as plastic granules, filtering and vibration of the raw materials, breaking down large lumps of raw materials into smaller pieces for easier subsequent processing. At the same time, it can prevent raw materials from clogging the screen plate, which would lead to low working efficiency of the device.

[0018] 2. This utility model incorporates a stirring rod on a limiting rod. During operation, the rotation of the sliding rod drives the limiting rod to rotate, causing the stirring rod to move. The movement of the limiting rod, in turn, drives the support rod to move, causing the protective cover to move. The movement of the protective cover, in turn, causes the rotating shaft to rotate around the sliding rod. Because the crown gear and gear two mesh with each other, the movement of the protective cover causing the rotating shaft to rotate will cause the rotating shaft to rotate, which in turn causes the stirring rod two to rotate. This achieves the goal of simultaneously agitating the raw materials during drying, improving the contact between the raw materials and heat, increasing drying efficiency, and breaking up clumps of raw materials, thereby improving the production quality of subsequent equipment.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 As shown, this utility model is a raw material drying device for polyethylene sheet extrusion molding, including a drying cylinder 1, a discharge pipe 101 fixedly connected to the outer wall of the drying cylinder 1, and a separator cylinder 102 fixedly connected to the inner wall of the drying cylinder 1. The outer wall of the separator cylinder 102 is provided with a screening mechanism 2. Through the discharge pipe 101, the discharge rate of the device can be freely controlled, and it is also convenient for the user to discharge the heated plastic particles.

[0030] The screening mechanism 2 includes a sliding rod sleeve 201. The outer wall of the sliding rod sleeve 201 is fixedly connected to the inner wall of the separator cylinder 102. The inner wall of the sliding rod sleeve 201 has several limiting grooves 202. A rotating rod 203 is rotatably connected to the inner wall of the sliding rod sleeve 201. An arc-shaped groove 204 is provided on the inner wall of the rotating rod 203. The arc-shaped groove 204 can limit the position of the sliding rod 205, so that the sliding rod 205 can only move up and down in an arc around the arc-shaped groove 204. The sliding rod 205 is slidably connected to the inner wall of the arc-shaped groove 204. The outer wall of the sliding rod 205 is slidably connected to the inner wall of the limiting groove 202. A screen plate 20 is fixedly connected to the top outer wall of the sliding rod 205. 6. The screen plate 206 can filter impurities in raw materials such as plastic granules to prevent impurities from entering the device and affecting subsequent production efficiency. The outer wall of the screen plate 206 is slidably connected to the inner wall of the separator cylinder 102. The inner wall of the drying cylinder 1 is fixedly connected to the motor 207. Several limiting shafts 208 are slidably connected to the bottom outer wall of the separator cylinder 102. The outer wall of the left limiting shaft 208 is fixedly connected to the bottom output of the motor 207. The limiting shaft 208 can limit the position of the pulley 209 to prevent the pulley 209 from falling off. At the same time, the pulley 209 on the limiting shaft 208 can transmit power to the half gear 211.

[0031] The outer wall of the right-side limiting shaft 208 is rotatably connected to the inner wall of the drying cylinder 1. A pulley 209 is fixedly connected to the outer wall of the end of the limiting shaft 208 near the separator cylinder 102. A belt 210 is driven to the outer wall of the pulley 209. Through the belt 210, the belt 210 can drive the limiting shaft 208. When the limiting shaft 208 of the motor 207 rotates, it will drive the pulley 209 on the side near the motor 207 to rotate. The rotation of the belt 210 can drive the pulley 209 on the other side of the limiting shaft 208 to rotate. A half gear 211 is fixedly connected to the outer wall of the end of the limiting shaft 208 near the separator cylinder 102. The outer wall of the rotating rod 203 near the half gear 211 is fixed. A gear 212 is connected, and the outer wall of the gear 212 meshes with the outer wall of the half gear 211. Since multiple half gears 211 mesh with the gear 212, the rotation of the half gear 211 can drive the gear 212 to reciprocate. The inner wall of the drying cylinder 1 is provided with a stirring mechanism 3. The stirring mechanism 3 includes a limiting rod 301. The outer wall of the limiting rod 301 is fixedly connected to the outer wall of the slide rod 205. Several stirring rods 302 are fixedly connected to the outer wall of the limiting rod 301. When the slide rod 205 rotates, it can drive the limiting rod 301 to rotate, thereby causing the multiple stirring rods 302 to rotate, stirring the plastic particles inside the separator cylinder 102, so that heat can be evenly introduced into the plastic particle pile.

[0032] Several support rods 303 are fixedly connected to the outer wall of the limiting rod 301. A protective cover 304 is fixedly connected to the outer wall of the support rod 303. The outer wall of the protective cover 304 is rotatably connected to the outer wall of the slide sleeve 201. Several rotating shafts 305 are rotatably connected to the inner wall of the protective cover 304. When the limiting rod 301 rotates, it will drive the support rods 303 to rotate, thereby causing the protective cover 304 to rotate. The protective cover 304 can drive the rotating shafts 305 to make circular motion around the slide 205. A second limiting rod 306 is fixedly connected to the outer wall of the end of the rotating shaft 305 away from the protective cover 304. Several stirring rods are fixedly connected to the outer wall of the second limiting rod 306. A crown gear 308 is fixedly connected to the outer wall of the rotating shaft 305 away from the stirring rod 307. Since the crown gear 308 and the second gear 309 mesh with each other, the rotating shaft 305 will rotate when it rotates. A second gear 309 is fixedly connected to the outer wall of the sliding sleeve 201 near the crown gear 308. The outer wall of the second gear 309 meshes with the inner wall of the crown gear 308. Several heating rods 310 are fixedly connected to the inner wall of the drying cylinder 1. When multiple heating rods 310 are activated, the heating rods 310 can generate heat. The heat passes through the holes of the separator cylinder 102 and enters the plastic particles to dry them.

[0033] One specific application of this embodiment is:

[0034] When the equipment is needed, the motor 207 is started, and then raw materials such as plastic granules are poured into the separator cylinder 102. Because the holes in the separator cylinder 102 are small, the plastic granules will not pass through it. The heating rod 310 and motor 207 are then started. The heat generated by the heating rod 310 passes through the holes in the separator cylinder 102 to dry the raw materials. The rotation of motor 207 drives the limiting shaft 208 on motor 207 to rotate, causing the pulley 209 near motor 207 to rotate, which in turn causes the belt 210 to rotate. The rotation of belt 210 drives the pulley 209 away from motor 207. The pulley 209 on the limiting shaft 208 on one side of the motor 207 rotates, causing the limiting shaft 208 on the side away from the motor 207 to rotate. The rotation of the limiting shaft 208 drives the half gear 211 to rotate, causing gear 212 to rotate. When the half gear 211 on the side closer to the motor 207 just disengages from gear 212, the half gear 211 on the side away from the motor 207 has just completed one revolution and successfully engaged with gear 212, allowing gear 212 to rotate in the opposite direction. When the half gear 211 on the side away from the motor 207 just disengages from gear 212, the half gear 209 on the side closer to the motor 207 has just completed one revolution and successfully engaged with gear 212, allowing gear 212 to rotate in the opposite direction. The half gear 211 on one side of the motor 207 also rotates one revolution and successfully engages with gear 212, allowing gear 212 to rotate in the opposite direction. When gear 212 reciprocates, it drives the rotating rod 203 to reciprocate. The rotation of the rotating rod 203 causes the sliding rod 205 to slide within the arc-shaped groove 204. The limiting groove 202 corrects the arc of the sliding rod 205 to a straight up-and-down movement along the direction of the limiting groove 202, thus causing the sliding rod 205 to reciprocate up and down, causing the screen plate 206 to vibrate and crush the raw material. Simultaneously, it prevents the raw material from clogging the screen plate 206. Above 6, the rotation of the slide bar 205 can drive the limit bar 301 to rotate, causing the stirring rod 302 to move. The movement of the limit bar 301 will drive the support rod 303 to move, causing the protective cover 304 to move. The movement of the protective cover 304 can drive the rotating shaft 305 to rotate around the slide bar 205. Since the crown gear 308 and the second gear 309 are meshed with each other, when the movement of the protective cover 304 drives the rotating shaft 305 to move, the rotating shaft 305 will rotate, which in turn causes the second stirring rod 307 to rotate, stirring the material in the separator 102, increasing the contact between the raw materials and heat, and improving the heat dissipation efficiency.
