Description

Technical Field

[0001] This utility model relates to the field of plastic grinding mills, specifically a multi-functional plastic grinding mill. Background Technology

[0002] Plastic grinding mills are widely used in the grinding and processing of various plastic materials in fields such as chemical industry, waste recycling, plastic pipe and profile manufacturing, and plastic modification. According to the grinding principle, grinding mills are mainly divided into two categories: rotor turbine grinding mills and disc grinding mills. According to the grinding method, they are divided into ambient temperature grinding mills and cryogenic grinding mills. The most common type we see is the ambient temperature grinding mill, also known as mechanical crushing.

[0003] Currently, plastic grinding mills require feeding plastic product scraps before grinding them. However, during the feeding process, dust and impurities in the plastic product scraps generate smoke and dust. When this smoke and dust diffuses into the air and is inhaled by workers, it can damage their respiratory tract and lungs. Therefore, a multi-functional plastic grinding mill is proposed to address the above problems. Utility Model Content

[0004] To overcome the shortcomings of existing technologies and solve the problem that existing plastic grinding mills require feeding plastic product scraps before grinding, and that the feeding process generates smoke and dust due to the dust and impurities contained in the plastic product scraps, which can damage the respiratory tract and lungs of workers when inhaled, this utility model proposes a multi-functional plastic grinding mill.

The other end of the filter element is fixedly connected to a dust collection shell. The bottom of the dust collection shell contacts the inner wall of the protective box. The top of the dust collection shell is fixedly connected to a suction pipe. One end of the suction pipe is fixedly connected to the inner cavity of the hopper. The top of the hopper is fixedly connected to a feed pipe. A second motor is fixedly connected to one side of the hopper. The output end of the second motor passes through the inner cavity of the hopper and is fixedly connected to a stirring rod. One end of the stirring rod is rotatably connected to the inner wall of the hopper through a bearing.

[0007] Preferably, a support frame is fixedly connected to the bottom of the protective box, and one side of the support frame is fixedly connected to the surface of the box.

[0008] Preferably, a filter screen is fixedly installed in the inner cavity of the suction pipe, and the filter screen is made of metal.

[0009] By setting up a filter screen, plastic product debris inside the hopper can be filtered out, preventing the debris from being sucked into the dust collection shell when the dust collection component removes dust from the hopper, thus avoiding waste of raw materials.

[0010] Preferably, a fixing ring is fixedly fitted onto the surface of the second motor, and one side of the fixing ring is fixedly connected to the surface of the hopper.

[0011] Preferably, a guide plate is fixedly sleeved on the surface of the grinding roller, and the guide plate is located at the upper end of the inner cavity of the box.

[0012] By setting up a guide plate, when the first motor drives the grinding roller to rotate, the guide plate rotates under the drive of the grinding roller, which can throw the plastic product debris on its surface to the inner wall of the box, thereby improving the grinding efficiency of the plastic grinding mill.

[0013] Preferably, a positioning ring is fixedly fitted on the surface of the first motor, and the bottom of the positioning ring is fixedly connected to the top of the housing.

[0014] Preferably, a limiting frame is movably fitted on the surface of the discharge pipe, and one side of the limiting frame is fixedly connected to the surface of the frame.

[0015] The advantages of this utility model are:

[0016] This invention, by incorporating a dust-collecting component, can adsorb and collect dust and impurities from plastic product scraps. Simultaneously, by utilizing a second motor to drive the stirring rod to rotate, it can reduce the feeding speed of plastic product scraps into the hopper cavity, thereby improving dust removal quality. This solves the problem of existing plastic grinding mills requiring the prior feeding of plastic product scraps before grinding. During the feeding process, the dust and impurities contained in the plastic product scraps generate smoke and dust, which, when diffused into the air and inhaled by workers, can damage their respiratory tract and lungs.

The fan 301 is fixedly installed on the top of the frame 1, the protective box 302 is fixedly installed on one side of the box 2, and the hopper 303 is fixedly installed on the top of the box 2. The inner cavity of the hopper 303 is connected to the inner cavity of the box 2. The input end of the fan 301 is fixedly connected to a duct 304. One end of the duct 304 passes through the inner cavity of the protective box 302 and is fixedly connected to a filter element 305. The other end of the filter element 305 is fixedly connected to a dust collection shell 306. The bottom of the dust collection shell 306 contacts the inner wall of the protective box 302, and the top of the dust collection shell 306 is fixedly connected to a suction pipe 307. One end of the suction pipe 307 is fixedly connected to the inner cavity of the hopper 303. The top of the hopper 303 is fixedly connected to the feed pipe 308. A second motor 309 is fixedly connected to one side of the hopper 303. The output end of the second motor 309 passes through the inner cavity of the hopper 303 and is fixedly connected to the stirring rod 310. One end of the stirring rod 310 is rotatably connected to the inner wall of the hopper 303 through a bearing. By setting the suction assembly 3, dust and impurities in plastic product debris can be adsorbed and collected. At the same time, the second motor 309 drives the stirring rod 310 to rotate, which can reduce the feeding speed of plastic product debris in the inner cavity of the hopper 303, thereby improving the dust removal quality.

[0028] Reference Figure 4The bottom of the protective box 302 is fixedly connected to a support frame 311, and one side of the support frame 311 is fixedly connected to the surface of the box 2. By setting the support frame 311, the protective box 302 can be supported and fixed, preventing the protective box 302 from falling off during use.

[0029] Reference Figure 4 The inner cavity of the suction pipe 307 is fixedly equipped with a filter screen 312, which is made of metal. By setting the filter screen 312, the plastic product debris in the inner cavity of the hopper 303 can be filtered, so as to avoid the plastic product debris being sucked into the inner cavity of the dust collection shell 306 when the suction component 3 removes dust from the inner cavity of the hopper 303, thus causing waste of raw materials.

[0030] Reference Figure 4 A fixing ring 313 is fixedly sleeved on the surface of the second motor 309, and one side of the fixing ring 313 is fixedly connected to the surface of the hopper 303. By setting the fixing ring 313, the second motor 309 can be fixed, and the second motor 309 on the ground will fall off during use.

[0031] Reference Figure 2 and Figure 3 A guide plate 9 is fixedly sleeved on the surface of the grinding roller 5. The guide plate 9 is located at the upper end of the inner cavity of the box 2. By setting the guide plate 9, when the first motor 4 drives the grinding roller 5 to rotate, the guide plate 9 rotates under the drive of the grinding roller 5, which can throw the plastic product debris on its surface to the inner wall of the box 2, thereby improving the grinding efficiency of the plastic grinding mill.

[0032] Reference Figure 3 A positioning ring 10 is fixedly sleeved on the surface of the first motor 4, and the bottom of the positioning ring 10 is fixedly connected to the top of the housing 2. By setting the positioning ring 10, the first motor 4 can be fixed and the position of the first motor 4 can be prevented from shifting during use.

[0033] Reference Figure 2 and Figure 3 A limiting frame 11 is movably sleeved on the surface of the discharge pipe 8, and one side of the limiting frame 11 is fixedly connected to the surface of the frame 1. By setting the limiting frame 11, the discharge pipe 8 can be limited, thereby improving the stability of the discharge pipe 8.

[0034] Working principle: During use, the operator starts the blower 301 and the second motor 309 using an external control switch. The second motor 309 rotates, driving the stirring rod 310 to rotate as well. The stirring rod 310 stirs the plastic product scraps inside the hopper 303, slowing down the feeding speed of the scraps. While the stirring rod 310 is stirring the plastic product scraps, the blower 301 draws air from the hopper 303, causing impurities and dust in the plastic product scraps to be sucked into the dust collection shell 306 through the filter screen 312. This process cleans the material before grinding. The plastic product debris is dusted. After dust removal, the plastic product debris falls into the inner cavity of the box 2 through the hopper 303. The operator starts the first motor 4 and the powder suction machine 7 using an external control switch. The powder suction machine 7 evacuates the air inside the box 2, making it a negative pressure state. Under the influence of air pressure, the plastic product debris moves downward. During the movement, the first motor 4 drives the grinding roller 5 to rotate at high speed, which can grind the plastic product debris. After grinding, the powder suction machine 7 sucks the powdered plastic into its inner cavity and discharges it into the discharge pipe 8.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
