Description

Technical Field

[0001] This utility model relates to the field of defoaming masterbatch processing technology, specifically to a defoaming masterbatch production equipment. Background Technology

[0002] Defoaming masterbatch is a functional additive used in the processing of polymer materials such as plastics and rubber. Its main function is to eliminate or inhibit bubbles generated during processing, and improve the appearance quality and performance of the product. The current production of defoaming masterbatch requires mixing, extrusion, cooling and pelletizing. In the pelletizing process, a rotary pelletizer is used to cut the cooled and solidified melt strip into pellets.

[0003] However, some polymer materials, such as polyethylene, polypropylene, and rubber, still have a certain degree of stickiness on their surface even after cooling. Therefore, after being cut by a rotary pelletizer, some granular defoaming masterbatch will stick together and form clumps, resulting in the particle size of the defoaming masterbatch exceeding the standard, affecting subsequent processing. Furthermore, a screening device is required to screen the clumped defoaming masterbatch in the later stage, which prolongs the production cycle. In view of the shortcomings of existing technology, we propose a defoaming masterbatch production equipment to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a defoaming masterbatch production equipment, which solves the problem that some polymer materials still have a certain degree of stickiness on their surface even after cooling. As a result, after being cut by a rotary pelletizer, some granular defoaming masterbatches will stick together and form clumps, leading to excessive particle size of the defoaming masterbatch produced and affecting subsequent processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a defoaming masterbatch production equipment, comprising a rotary pelletizer body, an equipment bin, a longitudinal cutter, a conveyor roller, a transverse rotary cutter, a feeding channel, and a discharging channel. The discharging channel is internally equipped with a dispersing mechanism, which includes:

[0006] A support rod is rotatably mounted on the inner wall of the discharge channel, and multiple sets of dispersing blades for dispersing the defoaming masterbatch after cutting are fixedly connected to the outer wall of the support rod.

[0007] The drive motor is located inside the main body of the rotary pelletizer and is connected to one end of the support rod.

[0008] The filter plate is fixedly installed on the inner wall of the discharge channel, and one end of the multiple sets of dispersing blades is in intermittent contact with the surface of the filter plate.

[0009] Preferably, the equipment compartment is provided with an anti-sticking component inside one end of the upper part of the discharge channel. The anti-sticking component is used to prevent the defoaming masterbatch from sticking together after cutting.

[0010] Preferably, the anti-adhesion component includes a rotatable funnel cylinder disposed on the inner wall of the equipment compartment and a connecting belt disposed between the funnel cylinder and the support rod, wherein the funnel cylinder contains anti-adhesion powder.

[0011] Preferably, one end of both the sluice tube and the support rod is fixedly connected to a pulley for positioning and supporting the connecting belt.

[0012] Preferably, the outer wall of the sieve cylinder is provided with a feeding port, and a sealing plate is snapped into the inside of the feeding port.

[0013] Preferably, the inner wall of the discharge channel has a cavity for receiving the drive motor and connecting belt, and the cavity is not connected to the interior of the discharge channel.

[0014] Preferably, the outer wall of the dispersing blade is fixedly connected with multiple sets of protrusions.

[0015] Preferably, a protective cover is rotatably connected to the end of the equipment compartment near the transverse roller cutter.

[0016] This utility model discloses a defoaming masterbatch production equipment, which has the following beneficial effects: The defoaming masterbatch production equipment, by setting a filter plate inside the discharge channel of the rotary pelletizer, can intercept the agglomerated defoaming masterbatch. Then, the agglomerated defoaming masterbatch is broken up by the dispersing blades controlled by the drive motor inside the discharge channel. The dispersing blades drive the funnel cylinder that receives anti-sticking powder to rotate under the action of the connecting belt, so that the anti-sticking powder can be sprayed on the surface of the defoaming masterbatch, avoiding the adhesion between the defoaming masterbatch, so that the size of the defoaming masterbatch corresponds to the required production size, thereby improving the overall production efficiency.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This application provides a defoaming masterbatch production equipment that solves the problem that some polymer materials still have a certain degree of stickiness on their surface even after cooling. As a result, after being cut by a rotary pelletizer, some granular defoaming masterbatches will stick together and form clumps, leading to excessive particle size of the defoaming masterbatch after production and affecting subsequent processing. The equipment breaks up the clumps of defoaming masterbatch.

[0027] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0028] This utility model discloses a defoaming masterbatch production equipment.

[0029] According to the appendix Figure 1-6As shown, the device includes a rotary pelletizer body 1, an equipment chamber 2 fixedly mounted on the top surface of the rotary pelletizer body 1, a longitudinal cutter 3, a conveyor roller 4, and a transverse rotary cutter 5 rotatably mounted inside the equipment chamber 2, a feeding channel 6 located on one side of the equipment chamber 2, and a discharge channel 7 located on the bottom surface of one end of the equipment chamber 2. A protective cover 21 is rotatably connected to the end of the equipment chamber 2 near the transverse rotary cutter 5. The inner wall of the discharge channel 7 is smooth, and the discharge channel 7 is designed with an inclination to reduce the retention of granular defoaming masterbatch inside the discharge channel 7. The rotary pelletizer body 1, equipment chamber 2, longitudinal cutter 3, conveyor roller 4, transverse rotary cutter 5, feeding channel 6, and discharge channel 7 constitute a rotary pelletizer. After the raw materials required for the production of defoaming masterbatch are prepared, the raw materials are fed into the extrusion equipment to produce strip-shaped melt. The strip-shaped melt is then cooled and fixed by a cooling device. After cooling and solidification, the strip-shaped melt enters the interior of the equipment chamber 2 through the feeding channel 6. At this time, the strip-shaped melt is located between the longitudinal cutter 3 and the conveyor roller 4. The longitudinal cutter 3 and the conveyor roller 4 are controlled by the drive equipment inside the equipment chamber 2 to feed the strip-shaped melt. When the strip-shaped melt is fed to a position close to the transverse roller cutter 5, the transverse roller cutter 5 is rolled and cut by the drive equipment inside the equipment chamber 2. After cutting, granular defoaming masterbatch is formed. The granular defoaming masterbatch is discharged in a concentrated manner through the discharge channel 7.

[0030] See attached document Figure 2-5 The discharge channel 7 is equipped with a dispersing mechanism 8. The dispersing mechanism 8 can prevent the granular defoaming masterbatch from sticking together. The dispersing mechanism 8 includes a support rod 81, which is rotatably mounted on the inner wall of the discharge channel 7. The outer wall of the support rod 81 is fixedly connected with multiple sets of dispersing blades 82 for dispersing the cut defoaming masterbatch. The outer wall of the dispersing blades 82 is fixedly connected with multiple sets of protrusions 821, which can increase the contact area between the granular defoaming masterbatch and the dispersing blades 82. The drive motor 83 is connected to one end of the support rod 81. The inner wall of the discharge channel 7 is provided with a set of cavities 85 for receiving the drive motor 83. The set of cavities 85 is not connected to the interior of the discharge channel 7. The filter plate 84 is fixedly mounted on the inner wall of the discharge channel 7, and one end of the multiple sets of dispersing blades 82 is intermittently in contact with the surface of the filter plate 84.

[0031] See attached document Figure 2-6An anti-sticking component 9 is installed inside one end of the equipment chamber 2 located at the top of the discharge channel 7. The anti-sticking component 9 is used to prevent the defoaming masterbatch from sticking together after cutting. The anti-sticking component 9 includes a rotatable hopper 91 installed on the inner wall of the equipment chamber 2 and a connecting belt 92 installed between the hopper 91 and the support rod 81. The inner wall of the discharge channel 7 has another set of cavities 85 for receiving the connecting belt 92. The other set of cavities 85 is not connected to the interior of the discharge channel 7. The inside of the hopper 91 contains anti-sticking powder, such as calcium carbonate and mica powder. One end of the hopper 91 and the support rod 81 are fixedly connected to a pulley 93 for positioning and supporting the connecting belt 92. The outer wall of the hopper 91 has a feeding port 94. A sealing plate 95 is snapped into the inside of the feeding port 94 so that anti-sticking powder can be added to the inside of the hopper 91 through the feeding port 94.

[0032] Specifically, when the granular defoaming masterbatch is discharged into the discharge channel 7, it will first accumulate on the surface of the filter plate 84. At this time, the granular defoaming masterbatch that is compatible with the filter holes of the filter plate 84 can pass directly through the filter plate 84. However, for the granular defoaming masterbatch that is stuck together, its overall volume is larger than the filter holes of the filter plate 84. Therefore, the drive motor 83 can be turned on. The drive motor 83 drives the multiple sets of dispersing blades 82 on the outer wall of the support rod 81 to rotate, so that the dispersing blades 82 can stir and disperse the granular defoaming masterbatch that is stuck together on one side of the filter plate 84.

[0033] At the same time, when the support rod 81 rotates, under the connection of the connecting belt 92, it will also drive the sieve cylinder 91 located at the top of the discharge channel 7 to rotate, so that the anti-sticking powder inside the sieve cylinder 91 falls into the interior of the discharge channel 7 under the action of power, and comes into contact with the granular defoaming masterbatch located on one side of the filter plate 84 of the discharge channel 7, so that the anti-sticking powder adheres to the outer surface of the granular defoaming masterbatch, further preventing the granular defoaming masterbatch from sticking and clumping together.

[0034] 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 claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
