Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a stirring device for producing plastic products. Background Technology

[0002] Plastic products are items made primarily from plastics, including household and industrial goods. Plastic granules are the raw material for processing plastic products. Plastic products are made by heating and melting plastic granules, then injecting them into molds and allowing them to cool and solidify. During production, various types of plastic granules are first mixed using a stirring device to ensure uniform mixing before being shaped using a melting device and molds.

[0003] Based on the above, the inventors have discovered the following problem: In the current production of plastic products, different types of plastic granules need to be poured into a mixing device, so that the plastic granules inside the mixing tank of the mixing device are piled up layer by layer in the order of pouring. When the mixing device starts mixing, it takes a long time to mix the bottom layer of plastic granules with the top layer of plastic granules, thereby reducing the mixing efficiency of different types of plastic granules.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a stirring device for the production of plastic products, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a stirring device for the production of plastic products, so as to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A mixing device for producing plastic products includes a feeding mechanism. The feeding mechanism includes a pair of supports, with a support cylinder connected to the center of the upper end of the pair of supports. A dispersing mechanism is provided inside the support cylinder. The dispersing mechanism includes a mixing cylinder. The bottom end of the mixing cylinder is connected to the bottom end of the inner part of the support cylinder, and a hollow cylinder is connected to the bottom end of the mixing cylinder. The bottom end of the hollow cylinder extends through the support cylinder to the outside. A top seat is provided at the upper end of the mixing cylinder. A circular hole is opened at the bottom end of the top seat. A circular plate is connected inside the circular hole. Two feed ports are opened on the upper end face of the circular plate, and a circular ring is connected to the upper end of the circular plate. The upper end face of the circular ring is inclined. A rotating rod is connected to the bottom end of the inner part of the mixing cylinder through a bearing. A dispersing block is connected to the upper end of the rotating rod. The outer wall of the dispersing block is inclined.

[0008] Furthermore, there is a distance between the upper end of the dispersion block and the upper end of the stirring cylinder, and the dispersion block and the circular plate are located on the same axis.

[0009] The beneficial effect of adopting the above-mentioned further solution is that by having a distance between the upper end of the dispersion block and the upper end of the mixing drum, there is a distance between the upper end of the dispersion block and the bottom end of the circular plate, so that the plastic particles can fall onto the dispersion block better.

[0010] Furthermore, four sets of stirring blades are connected to the outside of the rotating rod below the dispersing block.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by connecting four sets of stirring blades to the outside of the rotating rod below the dispersion block, it is convenient to mix and stir the two kinds of plastic particles in the mixing drum when the rotating rod rotates.

[0012] Furthermore, the bottom end of the mixing drum is connected to a discharge pipe, the bottom end of which extends through the hollow cylinder to the outside and is fitted with a solenoid valve.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by connecting the discharge pipe to the bottom of the mixing drum and extending the discharge pipe to the outside of the hollow drum, the plastic particles mixed inside the mixing drum can be discharged through the discharge pipe when the solenoid valve is opened.

[0014] Furthermore, a square groove is formed on the outer side of the hollow cylinder, and a driving mechanism is provided inside the square groove. The driving mechanism includes a power box, the outer wall of which is connected to the inner wall of the square groove. The bottom end of the rotating rod extends through the power box into the interior. A rotating shaft is rotatably connected to the side of the power box away from the rotating rod. Synchronous pulleys are fitted on the outside of both the rotating shaft and the rotating rod, and a synchronous belt is wound between a pair of synchronous pulleys.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, by setting a rotating shaft, when the rotating shaft rotates, it facilitates the rotation of the synchronous pulley sleeved on its outside, and under the transmission action of the synchronous belt, it causes another synchronous pulley and the rotating rod to rotate. Furthermore, a motor is provided on the bottom surface of the end of the power box away from the interior of the hollow cylinder, and the output end of the motor is connected to the rotating shaft via a transmission connection.

[0016] The advantage of adopting the above-mentioned further solution is that by setting up a motor, it is easy to drive the shaft to rotate when the motor is working.

[0017] Furthermore, mounting grooves are provided on both outer sides of the support cylinder, and screw feeders are connected inside the two mounting grooves. The opposite sides of the two screw feeders are connected to discharge pipes near the upper end, and the opposite ends of the two discharge pipes extend through the top seat into the interior.

[0018] The beneficial effect of adopting the above-mentioned further solution is that by opening mounting slots on both sides of the outside of the support cylinder, it is convenient to install the screw feeder. By setting up the screw feeder, the screw feeder consists of a shell, a drive motor, a drive shaft, and a screw conveying blade connected to the outside of the drive shaft. When the drive motor is started, it is convenient to realize the rotation of the drive shaft and the screw blade, so that the plastic particles move upward along the inside of the shell and are then discharged into the top seat through the discharge pipe.

[0019] Furthermore, the two screw feeders are connected to feed pipes near the bottom on opposite sides, and feeding boxes are connected to the bottom of both sides of the support cylinder. The bottom sides of the two feeding boxes are respectively connected to the upper ends of a pair of brackets, and the two feed pipes are located in the two feeding boxes respectively.

[0020] The beneficial effect of adopting the above-mentioned further solution is that, by setting up feeding boxes, the feed pipes of the two screw feeders are located in the two feeding boxes respectively. After the plastic granules are poured into the feeding boxes, they enter the screw feeders through the feed pipes. By connecting the bottom two sides of the feeding boxes to the upper ends of the two supports, the overall stability of the device is achieved.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: This stirring device for plastic product production, by setting a pair of supports, with a support cylinder connected to the upper center of the pair of supports, supports the cylinder. Through the coordinated use of a top seat, a ring, and a circular plate, when plastic granules are conveyed into the top seat, they fall under gravity and land on the upper surface of the ring. Since the upper surface of the ring is inclined inward, the plastic granules on the upper surface of the ring roll towards the center and fall onto the upper surface of the dispersion block through the center of the ring and the feed inlet. Since the outer wall of the dispersion block is inclined outward, the plastic granules on the dispersion block roll outward. By setting a rotating rod, when the rotating rod rotates, the dispersion block rotates, thereby achieving the umbrella-shaped flying and scattering of the two types of plastic granules, avoiding the accumulation of the two types of plastic granules in the stirring drum layer by layer according to the order of pouring, and improving the subsequent stirring and mixing efficiency.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-5This utility model provides a technical solution: a stirring device for producing plastic products, including a feeding mechanism 100, which includes a pair of supports 1001. A support cylinder 1002 is connected to the center of the upper end of the pair of supports 1001. A dispersing mechanism 200 is provided inside the support cylinder 1002. The dispersing mechanism 200 includes a stirring cylinder 2001. The bottom end of the stirring cylinder 2001 is connected to the bottom end of the inner part of the support cylinder 1002, and a hollow cylinder 2002 is connected to the bottom end of the stirring cylinder 2001. The bottom end of the 2 extends through the support cylinder 1002 to the outside. The upper end of the mixing cylinder 2001 is provided with a top seat 2003. A circular hole is opened at the bottom end of the top seat 2003, and a circular plate 2004 is connected inside the circular hole. Two feed inlets 2005 are opened on the upper surface of the circular plate 2004, and a circular ring 2006 is connected to the upper end of the circular plate 2004. The upper surface of the circular ring 2006 is inclined. A rotating rod 2007 is connected to the bottom end of the mixing cylinder 2001 through a bearing. A dispersing block 2008 is connected to the upper end of the rotating rod 2007. The outer wall of block 2008 is inclined. A pair of supports 1001 are provided, with a support cylinder 1002 connected to the upper center of each support 1001, thus supporting the support cylinder 1002. Through the coordinated use of a top seat 2003, a ring 2006, and a circular plate 2004, when plastic granules are conveyed into the top seat 2003, they fall under gravity and land on the upper surface of the ring 2006. Because the upper surface of the ring 2006 is inclined inwards, the plastic granules on the upper surface of the ring 2006... The particles roll towards the center and fall onto the upper surface of the dispersing block 2008 through the center of the ring 2006 and the feed inlet 2005. Since the outer wall of the dispersing block 2008 is inclined outward, the plastic particles on the dispersing block 2008 roll outward. By setting the rotating rod 2007, when the rotating rod 2007 rotates, the dispersing block 2008 rotates, thereby realizing the umbrella-shaped flying and scattering of the two types of plastic particles, avoiding the accumulation of the two types of plastic particles in the mixing drum 2001 layer by layer according to the order of pouring, and improving the subsequent mixing efficiency.

[0029] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5This utility model provides a technical solution: the upper end of the dispersing block 2008 is at a distance from the upper end of the stirring cylinder 2001, and the dispersing block 2008 and the circular plate 2004 are located on the same axis. Four sets of stirring blades 2009 are connected to the outside of the rotating rod 2007 below the dispersing block 2008. A discharge pipe 2010 is connected to the bottom end of the stirring cylinder 2001. The bottom end of the discharge pipe 2010 extends through the hollow cylinder 2002 to the outside and is fitted with a solenoid valve. The outside of the hollow cylinder 2002... A square groove is provided on the side, and a drive mechanism 300 is provided inside the square groove. The drive mechanism 300 includes a power box 3001. The outer wall of the power box 3001 is connected to the inner wall of the square groove. The bottom end of the rotating rod 2007 extends through the power box 3001 into the interior. A rotating shaft 3002 is rotatably connected to the side of the power box 3001 away from the rotating rod 2007. Synchronous pulleys 3003 are sleeved on the outside of both the rotating shaft 3002 and the rotating rod 2007. A synchronous belt is wound between a pair of synchronous pulleys 3003. 3004. By maintaining a distance between the upper end of the dispersion block 2008 and the upper end of the mixing drum 2001, and a distance between the upper end of the dispersion block 2008 and the bottom end of the circular plate 2004, the plastic particles can fall more effectively onto the dispersion block 2008. Four sets of stirring blades 2009 are connected to the outside of the rotating rod 2007, below the dispersion block 2008. When the rotating rod 2007 rotates, the four sets of stirring blades 2009 work together to stir the two types of plastic particles inside the mixing drum 2001. The mixing process is achieved by connecting a discharge pipe 2010 to the bottom of the mixing drum 2001, which extends to the outside of the hollow cylinder 2002. When the solenoid valve is opened, the mixed plastic granules inside the mixing drum 2001 are discharged through the discharge pipe 2010. A rotating shaft 3002 is provided; when the shaft rotates, the synchronous pulley 3003 mounted on its outside rotates, and under the transmission action of the synchronous belt 3004, another synchronous pulley 3003 and the rotating rod 2007 rotate. The technical solutions of the present invention 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 invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-5This utility model provides a technical solution: a motor 3005 is installed on the bottom surface of the end of the power box 3001 away from the interior of the hollow cylinder 2002. The output end of the motor 3005 is connected to the rotating shaft 3002. Mounting slots 1003 are provided on both outer sides of the support cylinder 1002. Screw feeders 1004 are connected inside the two mounting slots 1003. Discharge pipes 1005 are connected to the upper ends of the opposite sides of the two screw feeders 1004. The opposite ends of the two discharge pipes 1005 extend through the top seat 2003 into the interior. Feed pipes are connected to the bottom ends of the opposite sides of the two screw feeders 1004. Feed boxes 1006 are connected to both outer sides of the support cylinder 1002 near the bottom. The bottom ends of the two feed boxes 1006 are respectively connected to the upper ends of a pair of brackets 1001. Two feed pipes are located inside the two feed boxes 1006. The motor 3005... When the motor 3005 is working, it facilitates the rotation of the shaft 3002. By opening mounting slots 1003 on both sides of the support cylinder 1002, it is easy to install the screw feeder 1004. The screw feeder 1004 consists of a housing, a drive motor, a drive shaft, and screw conveying blades connected to the outside of the drive shaft. When the drive motor is started, it is easy to realize the rotation of the drive shaft and the screw blades, so that the plastic granules move upward along the inside of the housing and are discharged into the top seat 2003 through the discharge pipe 1005. By setting the feeding box 1006, the feeding pipes of the two screw feeders 1004 are located in the two feeding boxes 1006 respectively. When plastic granules are poured into the feeding box 1006, they enter the screw feeder 1004 through the feeding pipe. By connecting the bottom two sides of the feeding box 1006 to the upper ends of the two supports 1001, the overall stability of the device is achieved.

[0032] Specifically, the working principle of this mixing device for plastic product production is as follows: During use, plastic granules are poured into the feeding box 1006 and then enter the screw feeder 1004 through the feed pipe. Activating the screw feeder 1004 causes the plastic granules to be conveyed upwards within it, and then discharged through the discharge pipe 1005 into the top seat 2003. Once inside the top seat 2003, the plastic granules fall under gravity onto the upper surface of the ring 2006. Because the upper surface of the ring 2006 is inclined inwards, the plastic granules on the upper surface of the ring 2006 roll towards the center and pass through the center of the ring 2006 and the feed inlet 2005 onto the upper surface of the dispersing block 2008. Because the outer wall of the dispersing block 2008 is inclined outwards, the plastic granules on the dispersing block 2008 roll outwards. When the motor 3005 is started, it drives the rotating shaft 3002 to rotate, which facilitates the rotation of the synchronous pulley 3003 mounted on its outside. Under the transmission action of the synchronous belt 3004, another synchronous pulley 3003 and the rotating rod 2007 rotate, so that when the dispersion block 2008 rotates, the two kinds of plastic particles are scattered in an umbrella shape, which prevents the two kinds of plastic particles in the mixing drum 2001 from piling up layer by layer in the order of pouring, and improves the subsequent mixing efficiency. At the same time, when the rotating rod 2007 rotates, it is convenient to cooperate with the four sets of stirring blades 2009 to mix the two kinds of plastic particles in the mixing drum 2001. The discharge pipe 2010 is connected to the bottom of the mixing drum 2001 and extends to the outside of the hollow cylinder 2002. When the solenoid valve is opened, the mixed plastic particles in the mixing drum 2001 can be discharged through the discharge pipe 2010.
