Description

TECHNICAL FIELD

[0001] The utility model relates to the field of compatilizer, especially to a cutting equipment for compatilizer production. BACKGROUND

[0002] Compatilizer, also known as compatibilizer, is a kind of high molecular additive. It can promote the combination of two originally incompatible polymers by means of intermolecular bonding force, and then form a stable blend. Compatilizer plays a "bridge" role between two incompatible polymers through its special molecular structure. Its active functional groups can physically or chemically combine with the two polymers respectively, thereby enhancing their compatibility. In the production process, the premixed raw materials are first sent to a melt mixing device, such as a twin-screw extruder, for melt mixing and grafting reaction, so that the raw materials are fully melted and chemically reacted. Then the reacted melt is water-cooled and solidified to obtain a preliminary compatilizer product. Then cutting and granulation are carried out to obtain granular products meeting the requirements. The compatilizer particles after cutting have regular shape and size, which helps to reduce the space occupation during storage and transportation. In addition, cutting helps to quickly separate compatilizer from the production line, facilitating subsequent packaging and distribution.

[0003] For the above-mentioned related technology, the inventors found that after the compatilizer is melted by the extruder, continuous long strip-shaped materials are formed. These materials then enter the cold water tank for rapid cooling. The cooled materials are then transported to the cutting equipment for precise cutting. However, in this process, the extruder continuously extrudes the melted compatilizer into the cooling water tank, causing the water temperature in the cooling water tank to gradually rise as the cooling time prolongs. In the initial stage of cooling, the water temperature in the tank is relatively low, which can effectively cool the melted compatilizer quickly. As the cooling process continues, the water temperature gradually rises, causing the cooling speed of the compatilizer entering the tank subsequently to slow down. This temperature change can cause uneven temperature distribution inside the strip-shaped compatilizer to be cut.

[0004] If the cooling water temperature is too low, the compatilizer strip will solidify quickly, which not only increases the difficulty of cutting, but also may cause additional dust and debris during the cutting process. If these dust and debris are mixed into the finished product particles, they will seriously affect the appearance, color and transparency of the product, reducing the aesthetic and market acceptance of the product. In addition, too low cooling temperature may also cause uneven stress distribution inside the particles, making the particles more prone to breakage during use.

[0005] Conversely, if the temperature of the cooling water is too high, the solidification rate of the compatibilizer strip will slow down. This can easily lead to problems such as tailing and pellet sticking during pelleting, resulting in irregular pellet shapes. In the production of high-precision products, the use of irregularly shaped or sticky compatibilizer pellets will seriously affect product quality, such as reducing dimensional accuracy and increasing surface defects.

[0006] On the other hand, when the material strips are discharged from the cooling water tank and conveyed to the pelletizing equipment, some water stains will remain on the surface of the material strips. If there are water stains on the surface of the compatibilizer during the pelletizing process, it will also cause problems such as blockage and adhesion in the pelletizer. Therefore, how to prevent water stains from remaining on the surface of the material strips before pelletizing, while ensuring that the material strips are maintained within an appropriate temperature and stress range and meeting the quality requirements of the compatibilizer after pelletizing is the problem we need to solve. Now, a pelletizing equipment for compatibilizer production is proposed. Utility Model Content

[0007] The main technical problem solved by this utility model is to provide a pelletizing device for compatibilizer production, which effectively prevents residual water stains on the surface of the pellets before pelletizing, ensures that the pellets are maintained within an appropriate temperature and stress range, and meets the quality requirements of the compatibilizer after pelletizing.

[0008] To solve the above-mentioned technical problems, the present invention provides a pelletizing device for compatibilizer production, comprising: a housing and a pelletizing mechanism connected to one side of its top, wherein the inner cavity of the pelletizing mechanism is connected to the inner cavity of the housing, a filter guide plate located below the pelletizing mechanism and inclined is provided inside the housing, a discharge port is provided on one side of the housing, the bottom of the discharge port is not higher than the top of the lowest point of the filter guide plate, and one end of the discharge port is connected to an inclined guide shell;

[0009] A temperature control mechanism is connected to one side of the pelletizing mechanism. The temperature control mechanism includes a feed tube with a rectangular cross-section and a hollow cavity. Several guide rollers are installed at intervals on the inner side of the feed tube. Electric heating wires are connected to both sides of the inner wall of the feed tube. Several blowers are installed at intervals on the top of the feed tube. The blowing end of the blower is connected to the hollow cavity of the feed tube. Several air holes are opened on both sides of the inner wall of the feed tube.

[0010] The feed tube body has a clearance opening on the side wall near the pelletizing mechanism, and a closing door is connected to one side of the clearance opening via a hinge.

[0011] By adopting the above technical solution, the electric heating wire is used to heat and maintain a constant temperature environment inside the feed tube. When the feed strip enters the feed tube, the fan blows air onto the surface of the material through the air hole, which helps to remove water stains and impurities from the surface of the material, improves the pelleting quality, and blows the heat of the electric heating wire onto the feed strip and the inner cavity of the feed tube, so that the cut feed strip is within an appropriate temperature and stress range, so that the subsequent pelleting mechanism can pelletize it and obtain compatibilizer particles that meet the requirements. The compatibilizer particles are then transferred to the filter guide plate, guiding the cut particles to slide smoothly, and filtering out any dust and debris that may be present in the process, effectively improving the purity of the product and reducing the impact of dust and debris on the final product. At the same time, the inclined feed shell further guides the particles to flow out in an orderly manner. In addition, when the initial end of the feed strip is fed into the pelleting mechanism, the clearance port is opened by rotating the closing door to provide a channel for the feed strip to enter the pelleting mechanism, and the closing door is closed to prevent external contamination and heat loss.

[0012] In a preferred embodiment, the present invention can be further configured as follows: the pelletizing mechanism includes a pelletizing shell with a bottom opening and a movable blade rotatably connected therein. A drive motor for driving the movable blade to rotate is connected to one side of the pelletizing shell. A feed inlet is provided on the side of the pelletizing shell near the feed tube. A feed guiding assembly located inside the feed tube is provided on one side of the pelletizing shell. A fixed blade connected to the pelletizing shell is provided below one side of the movable blade. An electric roller is connected to the side of the fixed blade away from the movable blade. The top of the electric roller is located above the top of the fixed blade. A pressing assembly and an electric push rod for driving the pressing assembly to move up and down are connected above the electric roller. The electric push rod is installed on the top of the pelletizing shell. A second guide roller is rotatably connected to the side of the pelletizing shell near the feed inlet. The top of the second guide roller is located above the top of the electric roller.

[0013] By adopting the above technical solution, the material guiding component guides the material strip smoothly into the pelletizing shell, and the electric push rod drives the pressing component to contact the material strip, so that the material strip is located between the electric roller and the pressing component and in close contact. As the electric roller rotates, it is gradually conveyed so that the drive motor drives the moving blade to rotate and cooperates with the fixed blade to cut the compatibilizer strip material entering the pelletizing shell.

[0014] In a preferred embodiment, the present invention can be further configured as follows: the feeding assembly includes a feeding housing with an opening on one side, a guide roller three is rotatably connected inside the feeding housing, a plurality of annular grooves are spaced apart on the guide roller three, a limiting plate is inclinedly provided on the side of the feeding housing near the feeding port, and a limiting port corresponding to the annular grooves is spaced apart at the bottom of the limiting plate.

[0015] By adopting the above technical solution, multiple annular grooves are used to accommodate and support the material strip, making the material strip more stable during the conveying process, reducing cutting errors caused by shaking or deviation, preventing the material strip from clustering together for pelleting, ensuring consistent pellet size, improving finished product quality, and working in conjunction with the limiting port to restrict the conveying direction of the material strip and ensure its accurate guidance to the guide roller two, so that the material strip can pass smoothly and enter the cutting area, avoiding cutting errors caused by incorrect conveying direction.

[0016] In a preferred embodiment, the present invention can be further configured such that: the clamping assembly includes a U-shaped mounting base, a clamping roller is rotatably connected to the inner side of the U-shaped mounting base, the bottom of the clamping roller is located below the bottom of the U-shaped mounting base, and a rubber gasket is connected to the surface of the clamping roller.

[0017] By adopting the above technical solution, the U-shaped mounting base provides a stable support structure for the clamping roller, while allowing the clamping roller to rotate freely inside the U-shaped mounting base. This ensures that the clamping roller can flexibly adapt to material strips of different thicknesses. At the same time, it works with the electric push rod to maintain a stable clamping force. The clamping roller applies a uniform clamping force to the material strip by rotating, ensuring that the material strip can be tightly adhered to the electric roller during the conveying process. This allows the material strip to be conveyed with the rotation of the electric roller and prevents deviation or jumping during the conveying process, thereby improving cutting efficiency. In addition, the rubber gasket is used to increase the friction between the clamping roller and the material strip and ensure a tighter clamping process. The rubber gasket is made of soft and wear-resistant material, which can adapt to material strips of different materials and reduce damage to the material strip.

[0018] In a preferred embodiment, the present invention can be further configured such that: a vibration motor is connected to the bottom of the filter guide plate, a collection box with a top opening is placed below the filter guide plate, and the collection box is detachably connected to the housing.

[0019] By adopting the above technical solution, the vibration motor generates vibration to promote the separation and movement of the cut particles on the filter guide plate, prevent the particles from accumulating on the guide plate, and screen out the dust in the compatibilizer particles after pelleting, thereby improving product quality. At the same time, the screened compatibilizer dust is collected through the collection box for subsequent recycling.

[0020] In a preferred embodiment, the present invention can be further configured such that: universal wheels are connected to the bottom four sides of the box, and anchor bolts are symmetrically installed on the front and rear sides of the box.

[0021] By adopting the above technical solution, the casters are connected to the bottom of the box around the perimeter, providing mobility for the entire pelletizing system. Operators can move the system to a suitable position at any time according to production needs, thereby improving production efficiency and ease of operation. During use, the anchor bolts fix the box to the ground to prevent it from moving or shaking during operation.

[0022] In summary, the present invention includes at least one of the following beneficial technical effects of a pelletizing device for producing compatibilizers:

[0023] 1. The fan blows air onto the material surface through the air hole to remove water stains and impurities. At the same time, it blows the heat from the electric heating wire onto the inner cavity of the material strip and the guide tube, so that the material strip being granulated is within a suitable temperature and stress range, so that the subsequent pelletizing mechanism can pelletize it and obtain compatibilizer granules that meet the requirements.

[0024] 2. The material guiding assembly guides the material strip smoothly into the pelletizing shell, and the electric push rod drives the pressing assembly to contact the material strip, so that the material strip is located between the electric roller and the pressing assembly and is in close contact. As the electric roller rotates, the material strip is conveyed along with the rotation of the electric roller, and deviation or jumping occurs during the conveying process. At the same time, the drive motor drives the moving blade to rotate, and cooperates with the fixed blade to cut the compatibilizer strip material entering the pelletizing shell, thereby improving the cutting efficiency.

A closing door 67 is connected to one side of the clearance opening 66 via a hinge. A control electrical box is installed on the surface of the housing 1 to control the operation of various components and the temperature release of the electric heating wire 63. The clearance opening 66 is opened by rotating the closing door 67, providing a channel for the feed strip to enter the pelletizing mechanism 20. As the feed strip is gradually conveyed, the electric heating wire 63 heats and maintains a constant temperature environment inside the feed tube 61. The air holes 65 are also connected. 4. Air is blown onto the material surface through the air blowing hole 65 to remove water stains and impurities from the material surface. At the same time, the heat from the electric heating wire 63 is blown onto the inner cavity of the material strip and the guide tube 61, so that the material strip being granulated is within a suitable temperature and stress range, so that the subsequent pelletizing mechanism 20 can pelletize it and obtain compatibilizer particles that meet the requirements. In addition, the pelletized compatibilizer particles are transferred to the filter guide plate 3 to guide the cut particles to slide smoothly, and in this process, any dust and debris that may be present are filtered out, which effectively improves the purity of the product and reduces the impact of dust and debris on the final product.

[0039] The pelletizing mechanism 20 includes a pelletizing shell 21 with an open bottom and a movable blade 22 rotatably connected inside it. A drive motor 2a for driving the movable blade 22 to rotate is connected to one side of the pelletizing shell 21.

A feed guide assembly 24 located inside the feed tube 61 is provided on one side of the pelletizing shell 21. A fixed blade 25 connected to the pelletizing shell 21 is provided below one side of the movable blade 22. An electric roller 26 is connected to the side of the fixed blade 25 away from the movable blade 22. The top of the electric roller 26 is located above the top of the fixed blade 25.

The top of the guide roller 29 is located above the top of the electric roller 26.

As the electric roller 26 rotates, it is gradually conveyed, and the fixed blade 25 is fixed, forming a stable cutting area with the rotating moving blade 22. The material strip is guided into the cutting area by the electric roller 26. The moving blade 22 rotates under the drive of the drive motor 2a, and cooperates with the fixed blade 25 to form a shearing force, cutting the input material into uniform particles.

[0040] The feeding assembly 24 includes a feeding housing 241 with an opening on one side. A guide roller 242 is rotatably connected inside the feeding housing 241.

The bottom of the limiting plate 244 has limiting openings 245 corresponding to the annular grooves 243. The multiple annular grooves 243 are used to accommodate and support the material strip. By dispersing the support points, the stability of the material strip during the conveying process is improved, the cutting error caused by shaking or deviation is reduced, and the material strip is prevented from clustering together for cutting, ensuring that the particle size of the cut particles is consistent and improving the quality of the finished product. In addition, the limiting openings 245 are used to limit the conveying direction of the material strip and ensure that it is accurately guided to the guide roller 29, so that the material strip can pass smoothly and enter the cutting area, avoiding the cutting error caused by incorrect conveying direction and improving the accuracy and efficiency of cutting.

[0041] The clamping assembly 27 includes a U-shaped mounting base 271, with a clamping roller 272 rotatably connected to the inner side of the U-shaped mounting base 271. The bottom of the clamping roller 272 is located below the bottom of the U-shaped mounting base 271, and a rubber gasket 273 is connected to the surface of the clamping roller 272. The electric push rod 28 drives the U-shaped mounting base 271 to move downward, so that the clamping roller 272 applies a clamping force to the material strip, ensuring that the material strip can be tightly attached to the electric roller 26 during the conveying process. This allows the material strip to be conveyed with the rotation of the electric roller 26 and prevents deviation or jumping during the conveying process, thereby improving the cutting efficiency. The rubber gasket 273 is used to increase the friction between the clamping roller 272 and the material strip and ensure a tighter clamping process.

[0042] The implementation principle of this embodiment is as follows: During use, the electric heating wire 63 heats and maintains a constant temperature environment inside the feed tube 61. The blower 64 blows air onto the material surface through the blower hole 65 to remove water stains and impurities from the material surface. At the same time, the heat from the electric heating wire 63 is blown onto the material strip and the inner cavity of the feed tube 61, so that the cut material strip is within a suitable temperature and stress range. Then, the operator opens the closing door 67, and through the clearance port 66, the initial section of the material strip is inserted into the feed tube 61 and manually guided into the feed assembly 24. Through the guide roller 29, its end is guided to the electric feed assembly 24. Between the roller 26 and the pressing roller 272, the electric push rod 28 drives the U-shaped mounting base 271 to move downward, so that the pressing roller 272 applies a pressing force to the material strip. At this time, the material strip is located between the electric roller 26 and the pressing assembly 27 and is in close contact. As the electric roller 26 rotates, it is gradually conveyed. The fixed blade 25 is fixed and forms a stable cutting area with the rotating moving blade 22. The material strip is guided into the cutting area by the electric roller 26. The moving blade 22 rotates under the drive of the drive motor 2a and cooperates with the fixed blade 25 to form a shearing force, cutting the input material into uniform particles.
