Description

Technical Field

[0001] This utility model relates to the field of resin production technology, specifically to a mixing device for resin production that assists in crushing. Background Technology

[0002] As a core raw material for polymer materials, resin is widely used in plastics, coatings, adhesives, composite materials and other fields. The production process usually includes the pretreatment of raw materials (crushing, screening), mixing, reaction polymerization, granulation and other steps. Among them, the uniformity of resin mixing directly affects the physical and chemical properties of resin products. Traditional processing technology requires first crushing and dispersing the agglomerates in the resin raw materials with a crusher, and then transferring them to a mixer for mixing after screening.

[0003] However, this method requires manually or pneumatically conveying the crushed material to the mixing equipment, which poses a risk of dust leakage and waste. In addition, the step-by-step operation results in long idle time of the equipment and a large footprint. It is particularly unsuitable for small-batch, multi-variety production scenarios and is inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to provide a mixing device for resin production that assists in crushing, so as to solve the problems of inconvenient transportation and waste of resin materials after crushing mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for resin production with auxiliary crushing, comprising a mixing bin, one end of which is a bucket-shaped design, and an electromagnetic valve is fixedly installed on the outer surface of one end of the mixing bin. An installation platform is fixedly installed on the end of the mixing bin away from the electromagnetic valve, and a drive motor is fixedly installed on the end of the installation platform away from the mixing bin. The output end of the drive motor penetrates through the outer surface of the installation platform. A crushing bin is fixedly installed on one outer surface of the mixing bin. A crushing blade is rotatably installed inside the crushing bin, and one end of the crushing blade penetrates through the outer surface of the crushing bin. The crushing blade is rotatably installed inside the crushing bin and is connected to the output end of the drive motor.

[0006] Preferably, an inspection door is rotatably installed on the side surface of the crushing chamber, and the outer surface of the inspection door is tightly fitted with the outer surface of the crushing chamber. The crushing chamber and the inspection door are fixed together with bolts. The bottom of the crushing chamber is designed to be inclined, and a filter screen is inserted and installed on the side surface of the crushing chamber. A screw handle is threaded on the side surface of the crushing chamber, and the screw handle is fitted with the outer surface of the filter screen.

[0007] Using the above technical solution, the inside of the crushing chamber can be cleaned or the crushing blades repaired through the inspection door. At the same time, the filter screen can be fixed by using the screw handle, so that the filter screen can separate the resin crushed to the qualified size. The resin particles can move along the inclined surface of the crushing chamber, and the unqualified resin can be left in the crushing chamber for further crushing. Different specifications of filter screens can be replaced according to different processing and mixing requirements to obtain resin particles of different sizes. There will be no quality problems caused by the size of the resin particles. It is convenient to use and improves the mixing quality of resin.

[0008] Preferably, a first pulley is fixedly installed on the outer surface of the crushing blade, an agitator is rotatably installed inside the mixing chamber, and the agitator and the mixing chamber are concentrically designed. A second pulley is rotatably installed on the outer surface of the mounting platform, and a belt is provided between the second pulley and the first pulley. The diameter of the second pulley is smaller than the diameter of the first pulley.

[0009] Using the above technical solution, the rotation of the drive motor can drive the first pulley to rotate, which in turn drives the second pulley to rotate simultaneously. This allows the crushing blade to break up the resin while simultaneously rotating the stirring blade. After a certain amount of resin material is added and crushed, the resin of the appropriate size will gradually enter the mixing chamber, allowing the resin to gradually mix with the auxiliary materials during mixing. At the same time, the diameter difference between the first and second pulleys allows the stirring blade to rotate at a low speed while the crushing blade rotates, improving the uniformity of mixing.

[0010] Preferably, a coupling is fixedly installed on the outer surface of the second pulley, and the coupling is connected to the stirring blade, and another coupling is provided between the first pulley and the drive motor.

[0011] By adopting the above technical solution, the use of a coupling allows the drive motor and the crushing blade to be connected to each other, and the second pulley and the stirring blade to be connected to each other, which improves the protection of the drive motor. At the same time, when the belt is worn and damaged, the coupling can be removed, and the belt can be quickly installed without disassembling a large number of parts.

[0012] Preferably, an exhaust vane is rotatably mounted inside the installation platform and is connected to a second pulley. A filter dust collection drawer is slidably installed inside the installation platform and is in close contact with the outer surface of the installation platform.

[0013] Using the above technical solution, when the second pulley rotates, the suction blades will rotate along with it, allowing the device to work simultaneously with crushing and mixing, and drawing air into the installation platform. The dust generated during the operation of the device is filtered and collected through the dust collection drawer, reducing environmental pollution and resin waste caused by dust spreading everywhere during processing.

[0014] Preferably, a threaded steel wire hose is fixedly installed on the outer surface of the crushing chamber, and the other end of the threaded steel wire hose is connected to the installation platform.

[0015] Using the above technical solution, the crushing chamber and the installation platform can be connected by a threaded steel wire hose. At the same time, the rigidity of the threaded steel wire hose itself ensures that the hose will not deform and cause airflow obstruction when the exhaust blades rotate to extract air.

[0016] Preferably, a feeding hopper is fixedly installed on the outer surface of the mixing hopper, and the feeding hopper is located outside the installation platform. A through hole is opened on the outer surface of the crushing hopper, and the through hole of the crushing hopper is connected to the feeding pipe.

[0017] Using the above technical solution, auxiliary materials can be fed into the mixing bin through the feeding hopper, while the through holes on the outer surface of the crushing bin allow resin materials to be fed through the feeding pipe. At the same time, when the exhaust blades rotate to extract air, external air can enter the mixing bin and crushing bin through the through holes of the feeding hopper and the mixing bin, preventing dust generated during mixing and crushing from escaping. This facilitates feeding while reducing the probability of dust escaping from the through holes of the feeding hopper and the mixing bin.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the mixing device for resin production with auxiliary crushing function:

[0019] 1. By connecting the mixing chamber and the crushing chamber, after the resin raw material is put into the crushing chamber, the rotation of the drive motor can drive the crushing blade to rotate, so that the crushing blade can crush the resin material in the crushing chamber. The crushed resin particles of the appropriate size can pass through the filter screen and move along the inclined surface of the crushing chamber. After the resin is crushed to the appropriate size, it can be directly discharged into the mixing chamber for mixing, without the need to transport and move the crushed resin, which improves the convenience of use and reduces resin waste.

[0020] 2. When different sizes of resin particles are required, simply loosen the screw handle and pull the filter screen out of the crushing chamber to easily clean the filter screen. Different sizes of filter screens can be replaced to obtain resin particles of different sizes after crushing, allowing the device to be flexibly adjusted and used according to processing requirements.

[0021] 3. When the drive motor rotates, it will drive the first pulley to rotate, which in turn drives the second pulley to rotate. The difference in diameter between the first and second pulleys prevents the stirring blades from rotating too fast, thus reducing the heat generated by excessive stirring blade speed. This allows the crushing blades and stirring blades to rotate synchronously, working together to crush and discharge the resin. This ensures that the resin can be evenly mixed with the auxiliary materials and reduces resin adhesion caused by high temperature.

[0022] 4. When the drive motor is running, the suction blades will rotate along with it. At this time, the suction blades will extract the gas and dust from the mixing chamber and crushing chamber, allowing the gas and dust to move along the direction of the threaded steel wire hose and enter the interior of the installation platform. The gas can then be filtered and collected through the dust collection drawer, preventing the dust generated during the operation of the device from spreading around and causing environmental pollution, and enabling the dust to be recycled.

Detailed Implementation

[0030] 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.

[0031] Please see Figure 1-6 This utility model provides a technical solution: a mixing device for resin production with auxiliary crushing, including a mixing bin 1. One end of the mixing bin 1 is designed as a bucket, and an electromagnetic valve 18 is fixedly installed on the outer surface of one end of the mixing bin 1. An installation platform 4 is fixedly installed on the end of the mixing bin 1 away from the electromagnetic valve 18, and a drive motor 5 is fixedly installed on the end of the installation platform 4 away from the mixing bin 1. The output end of the drive motor 5 passes through the outer surface of the installation platform 4. A crushing bin 2 is fixedly installed on one outer surface of the mixing bin 1. A crushing blade 6 is rotatably installed inside the crushing bin 2, and one end of the crushing blade 6 passes through the outer surface of the crushing bin 2. The crushing blade 6 is rotatably installed inside the crushing bin 2 and is connected to the output end of the drive motor 5.

[0032] The hopper design of the mixing hopper 1 allows the resin to be easily discharged from the mixing hopper 1 after mixing by simply opening the solenoid valve 18. The rotation of the drive motor 5 drives the crushing blade 6 to rotate, allowing the resin fed into the crushing hopper 2 to be crushed as the crushing blade 6 rotates. After the resin is crushed to the required level, it is discharged into the mixing hopper 1. This eliminates the need for transportation after the resin is crushed, allowing it to directly enter the mixing hopper 1. This improves the convenience of use and prevents the waste of resin during transportation.

[0033] A maintenance door 3 is rotatably installed on the side surface of the crushing chamber 2, and the outer surface of the maintenance door 3 is tightly fitted with the outer surface of the crushing chamber 2. The crushing chamber 2 and the maintenance door 3 are fixed with bolts. The bottom of the crushing chamber 2 is designed to be inclined, and a filter screen 8 is inserted and installed on the side surface of the crushing chamber 2. A screw handle 9 is threaded on the side surface of the crushing chamber 2, and the screw handle 9 is fitted with the outer surface of the filter screen 8.

[0034] The crushing blades 6 inside the crushing chamber 2 can be maintained and cleaned through the inspection door 3, and can also be replaced. After the resin is crushed by the crushing blades 6 in the mixing chamber 1, the crushed resin will move with the rotation of the crushing blades 6 and be filtered by the filter screen 8. This allows resin particles of different sizes to enter the interior of the mixing chamber 1 along the inclined surface of the crushing chamber 2. When resin particles of different diameters are needed, the filter screen 8 can be pulled out from the crushing chamber 2 simply by loosening the screw handle 9. By replacing the filter screen 8 with different specifications, resin particles of different sizes can be obtained. The filter screen 8 can also be easily pulled out for cleaning, making it easy to filter out qualified resin particles and continue to crush unqualified resin particles. This allows for flexible adjustment according to processing needs while reducing the decline in mixing quality caused by unqualified particles.

[0035] A first pulley 10 is fixedly installed on the outer surface of the crushing blade 6. An agitator 13 is rotatably installed inside the mixing chamber 1, and the agitator 13 and the mixing chamber 1 are concentrically designed. A second pulley 11 is rotatably installed on the outer surface of the mounting platform 4, and a belt 12 is provided between the second pulley 11 and the first pulley 10. The diameter of the second pulley 11 is smaller than the diameter of the first pulley 10.

[0036] By using the diameter difference between the first pulley 10 and the second pulley 11, the rotation speed of the stirring blade 13 can be reduced, preventing the resin from softening and sticking due to excessive rotation speed. At the same time, when the drive motor 5 drives the first pulley 10 to rotate, the belt 12 will drive the second pulley 11 to rotate together, allowing the crushing blade 6 and the stirring blade 13 to rotate simultaneously. This allows the resin to be crushed and stirred at the same time, so that the qualified resin particles can be evenly discharged into the mixing chamber 1, so as to evenly mix the resin material and auxiliary materials.

[0037] A coupling 7 is fixedly installed on the outer surface of the second pulley 11, and the coupling 7 is connected to the stirring blade 13. Another coupling 7 is provided between the first pulley 10 and the drive motor 5.

[0038] By using coupling 7, the probability of damage to drive motor 5 due to jamming between crushing blade 6 and stirring blade 13 can be reduced. At the same time, when belt 12 is damaged and broken, coupling 7 can be loosened and removed, thereby disconnecting the second pulley 11, stirring blade 13, drive motor 5 and first pulley 10, allowing belt 12 to pass through and be installed between first pulley 10 and second pulley 11, reducing the difficulty of replacing belt 12 and reducing the probability of damage to drive motor 5.

[0039] An exhaust vane 14 is rotatably mounted inside the mounting platform 4, and the exhaust vane 14 is connected to the second pulley 11. A filter dust collection drawer 16 is slidably inserted inside the mounting platform 4, and the filter dust collection drawer 16 is tightly fitted to the outer surface of the mounting platform 4.

[0040] As the drive motor 5 starts, the exhaust vane 14 rotates along with it, allowing the dust generated during the operation of the device to be drawn into the interior of the mounting platform 4. At the same time, the air can be filtered through the dust filter drawer 16, allowing the dust to be collected in the dust filter drawer 16, so that the dust generated during the operation of the device will not spread around and cause environmental pollution. At the same time, the dust can also be recycled to reduce the waste of resin.

[0041] A threaded steel wire hose 15 is fixedly installed on the outer surface of the crushing chamber 2, and the other end of the threaded steel wire hose 15 is connected to the installation platform 4.

[0042] The use of threaded steel wire hose 15 allows the crushing chamber 2 and the installation platform 4 to be connected to each other. At the same time, the rigidity of the threaded steel wire hose 15 itself ensures that it will not deform or become blocked during use, thus preventing poor air intake.

[0043] A feeding hopper 17 is fixedly installed on the outer surface of the mixing bin 1, and the feeding hopper 17 is located outside the installation platform 4. A through hole is opened on the outer surface of the crushing bin 2, and the through hole of the crushing bin 2 is connected to the feeding pipe.

[0044] The auxiliary materials can be easily fed into the feeding hopper 17, preventing them from scattering. At the same time, the through holes on the outer surface of the crushing chamber 2 allow the feeding pipe to be inserted to send the resin raw materials into the crushing chamber 2. The through holes of the feeding hopper 17 and the crushing chamber 2 allow air to circulate in the device when the exhaust vane 14 rotates to extract air, so that negative pressure can be formed inside the mixing chamber 1 and the crushing chamber 2, preventing the dust generated during the operation of the device from floating out.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
