Description

Technical Field

[0001] This utility model relates to the field of material cutting machine technology, and in particular to a material cutting machine. Background Technology

[0002] During the cutting and processing of thermoplastic elastomer masterbatches, the high viscosity of the material itself causes it to easily stick together at the pelletizer's discharge port, affecting the smoothness and efficiency of the discharge. This sticking not only leads to material agglomeration, increasing the difficulty of subsequent processing, but can also cause equipment blockage and reduce production efficiency.

[0003] Currently, the main method for addressing the issue of material sticking at the pelletizer outlet is to manually loosen it with sticks. While this method can alleviate the sticking phenomenon to some extent, it has the following drawbacks: low efficiency, safety risks, and inconsistent quality. Given these shortcomings, the pelletizer should be able to effectively reduce material sticking at the outlet by dispersing, guiding, and blowing away the material, thereby improving production efficiency and quality stability.

[0004] When the pelletized material passes through the discharge port, it sticks to each other or adheres to the inner wall due to its high viscosity, resulting in poor discharge and material agglomeration that causes equipment blockage. In view of this, a material cutting machine is provided. Utility Model Content

[0032] In order to further explain the technical means and effects that the utility model adopts to realize the predetermined utility model purposes, the following will be combined with the preferred embodiments, and the specific implementation, structure, features and effects according to the utility model will be described in detail as follows.

[0033] Please refer to Figures 1-8The purpose of the present embodiment is to provide a cutting machine, which comprises a cutting machine 1 for cutting thermoplastic elastomer master batch and a discharge port 11 fixedly connected to the bottom of the cutting machine 1, a circular fixed plate 2 is fixedly arranged at the upper end of the discharge port 11, a plurality of shunt strips 21 are arranged in an annular array on the fixed plate 2, an air outlet ring 3 for uniformly blowing the cut particles is embedded in the discharge port 11, and a vibrating part 6 is fixedly arranged at the lower end of the discharge port 11, which is used to further disperse the material.

[0034] During the cutting and processing of thermoplastic elastomer master batch, the materials are easy to stick together due to friction and static electricity. The upper end of the discharge port 11 is cylindrical, and the lower end is conical, gradually guiding the material to pass through.

[0035] The fixed plate 2 is a ring with a diameter gradually decreasing from one end to the other, which helps to further guide the material to the center of the discharge port 11, preparing for subsequent dispersion and discharge. The shunt strips 21 are streamline-shaped, which can guide the material to flow smoothly along the surface, thereby more effectively dispersing the material and reducing the risk of blockage. The inclination angles of the shunt strips 21 are different, ranging from 0 to 45 degrees.

[0036] The fixed plate 2 is in an inwardly inclined state, and a plurality of limiting protrusions 22 are arranged on the upper surface of the fixed plate 2. When the materials that stick together pass through the limiting protrusions 22, these limiting protrusions 22 will play a rough separation role. They separate the materials that stick together through physical contact and friction, thereby reducing the agglomeration of materials during the discharging process and helping to improve the dispersibility and uniformity of the materials, providing better conditions for subsequent processing steps. The lower surface of the fixed plate 2 is fixedly connected with an elastic layer 23.

[0037] A plurality of air outlets 31 are arranged in an annular array on the inner side of the air outlet ring 3. The annular air outlet ring 3 ensures that the air can be uniformly blown from all directions to the material, and the air outlets 31 are arranged in a downward inclination, reducing the risk of the material being blown upward, ensuring that the material can stably flow downward along the discharge port 11. The downwardly inclined air outlets 31 can also provide a certain degree of guiding force to help the material flow more smoothly through the discharge port 11. Even if a small amount of material is bounced upward due to the collision with the inner wall of the discharge port 11, it will be bounced downward when it encounters the elastic layer 23 on the lower surface of the fixed plate 2. The softness and elasticity of the elastic layer 23 not only can absorb the impact force of these materials, but also can guide them back to the correct flow path, thereby avoiding the risk of material blockage or bouncing back into the cutting machine 1.

[0038] Therefore, the fixed plate 2 not only can guide the material to flow into the discharge port 11, but also can further block the material from being blown or bounced into the cutting machine 1, thereby ensuring the continuity and stability of the discharging process.

[0039] Several blowers 7 are arranged in a ring array through the side wall of the discharge port 11, and one end of each blower 7 is fixedly connected to the air outlet ring 3, so that the airflow can be directly transmitted from the blower 7 to the air outlet 31 of the air outlet ring 3. This tight integration not only reduces airflow loss, but also ensures that the air can be blown evenly and stably onto the material. The blowers 7 are small blowers 7, and the wind force is not enough to disturb the material and make it collide. However, the airflow provided by these small blowers 7 can act gently on the material, promote its dispersion and reduce adhesion, and avoid the problems of material loss and unstable discharge caused by excessive wind force.

[0040] The inner wall of the discharge port 11 is provided with several guide plates 4 in a ring array hinged together. The guide plates 4 are arc-shaped and located below the air outlet ring 3. The downward tilt angle of the guide plates 4 can be adjusted according to the characteristics or quantity of the material. The airflow generated by the air outlet ring 3 can be further guided by the guide plates 4 to enhance the dispersion effect. By adjusting the tilt angle of the guide plates 4, the flow path of the material can be further optimized, reducing the wear and deformation of the material during the flow process and improving the product quality.

[0041] The material blown by the air outlet ring 3 may not be completely dispersed. Therefore, the discharge port 11 is embedded with several elastic strips 5 in a ring array. The material of the elastic strips 5 is preferably polyurethane, which has good elasticity and wear resistance, can withstand the impact force when the material hits, and also has good self-recovery properties, which can quickly return to the original shape after the material hits, thereby continuously providing effective rebound force. The elastic strips 5 are located in the conical section of the discharge port 11. Since the materials stuck together have a certain weight, when the materials stuck together hit the elastic strips 5, they will be rebounded and dispersed due to the elasticity of the elastic strips 5. This can effectively break the sticky state between the materials and promote their further dispersion. Moreover, the elasticity of the elastic strips 5 only works on the sticky materials with a certain weight, and will not affect the small materials that have already been dispersed. This means that while promoting the dispersion of materials, no additional disturbance or damage to the already formed good flow state will be introduced, which helps to reduce the loss of materials during the discharge process.

[0042] The vibrating part 6 includes a mounting base 62 fixedly installed at the lower end of the discharge port 11. A vibrating motor 621 is fixedly installed inside the mounting base 62. A connecting plate 61 is provided above the mounting base 62. The connecting plate 61 is conical and has an uneven texture on its surface. The output shaft of the vibrating motor 621 is fixedly connected to the center of the connecting plate 61.

[0043] Several springs 63 are fixedly arranged in a circular array on the upper surface of the mounting base 62. These springs 63 serve as connecting parts, with one end fixedly connected to the mounting base 62 and the other end fixedly connected to the inner wall of the connecting plate 61. The connecting plate 61 is driven to vibrate and disperse the material by the vibration motor 621. Under the action of the springs 63, the connecting plate 61 has a certain floating range. This floating can further enhance the material dispersion effect because the material is subjected to slight impacts and rebounds from different directions of the connecting plate 61 while being vibrated.

[0044] For some thermoplastic elastomers, temperature changes can significantly affect their viscosity. A cavity 111 is provided on the inner wall of the discharge port 11. The cavity 111 is used to install a temperature control device, which can be a heating device or a cooling device. By adjusting the temperature of the discharge port 11 through the temperature control device, the viscosity of the material is reduced, preventing it from adhering to the inner wall of the discharge port 11. The heating device is preferably an electric heating wire, and the cooling device is preferably a cooling water pipe. By adjusting the temperature of the discharge port 11, the viscosity of the material during the discharge process is effectively reduced, thereby reducing the possibility of it adhering to the inner wall of the discharge port 11.

[0045] In practical use, the temperature control device inside the cavity 111 is activated to preheat or precool the discharge port 11 to the set temperature to reduce the viscosity of the material. The cutting machine 1 is started to cut the thermoplastic elastomer masterbatch, and the blower 7 is activated to blow air evenly into the discharge port 11 through the air outlet ring 3. The cut material enters the discharge port 11 through the fixed plate 2. The diverting strip 21 on the fixed plate 2 guides the material to gather towards the center, and the limiting protrusion 22 on it roughly separates the material. The airflow generated by the blower 7 is blown evenly into the material through the air outlet ring 3 to further disperse the sticky material. The angle of the guide plate 4 is adjusted according to the material characteristics to optimize the flow path of the material. Subsequently, when the sticky material hits the elastic strip 5, it is bounced and dispersed due to the elasticity of the elastic strip 5. The vibration part 6, through the action of the vibration motor 621 and the spring 63, causes the connecting plate 61 to vibrate, further enhancing the dispersion effect of the material, until the material is completely discharged through the discharge port 11, and the equipment is turned off.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
