Description

Technical Field

[0001] This utility model relates to the field of raw material processing, specifically a raw material grinding device. Background Technology

[0002] Polyurethane is a polymer compound, known as the "fifth largest plastic". It is a polymer material formed by polycondensation reaction of polyols and polyisocyanates. It has good plasticity, wear resistance, chemical resistance, heat resistance and cold resistance.

[0003] Polyurethane grinding equipment is a specialized device for grinding polyurethane materials. It is a highly efficient, energy-saving, and easy-to-operate machine suitable for grinding polyurethane materials. It plays a vital role in the production and processing of polyurethane materials and has broad application prospects and market potential.

[0004] Existing raw material grinding devices generally use grinding rollers to squeeze and grind raw materials. However, during use and observation, it has been found that this grinding method is prone to causing raw materials to adhere to the surface of the grinding rollers, affecting subsequent grinding work.

[0005] Therefore, a raw material grinding device is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The raw material grinding device of this utility model includes a box; two sets of motors are fixedly connected to the middle of the box; a connecting shaft is fixedly connected to the output end of the motor; the connecting shaft and the box are through-connected and rotatably connected; a grinding roller is fixedly connected to the end of the connecting shaft; a pair of air supply pipes are through-connected to the side wall of the box; an air supply box is connected to the end of the air supply pipes; multiple air outlet pipes are fixedly connected to the air supply box; the air outlet pipes and the air supply pipes are connected. By through-connecting the air supply pipes to the side wall of the box, connecting the air supply box to the end of the air supply pipes, and connecting multiple air outlet pipes to the air supply box, air is injected into the air supply pipes during the grinding process and blown towards the surface of the grinding roller. This can clean the polyurethane raw material adhering to the surface of the grinding roller during the grinding process, reducing the situation where the polyurethane raw material adheres to the surface of the grinding roller, resulting in incomplete grinding of the polyurethane by the grinding roller.

[0008] Preferably, a pair of guide plates are fixed to the inner side wall of the box; multiple diverter plates are fixed to the surface of the guide plates; by fixing the guide plates to the inner side wall of the box and fixing multiple diverter plates to the guide plates, the raw materials can be guided when they are placed inside the box, and the situation where the raw materials fall onto the surface of the air box and cannot be ground can also be reduced when the raw materials are placed inside the box.

[0009] Preferably, a plurality of first striking blocks are fixedly connected to the connecting shaft; a second striking block is fixedly connected to the surface of the guide plate; the first striking blocks and the second striking blocks are arranged correspondingly. By fixing a plurality of first striking blocks to the connecting shaft and a second striking block to the surface of the guide plate, the rotating first striking blocks can strike the second striking blocks, thereby reducing the accumulation of polyurethane raw materials on the surface of the guide plate when the polyurethane raw materials are placed inside the box.

[0010] Preferably, a pair of connecting blocks are fixed to the inner side wall of the box; a dispersion plate is fixed between the pair of connecting blocks. By fixing the dispersion plate between the pair of connecting blocks, the polyurethane material after grinding can be dispersed, reducing the situation where the ground polyurethane raw material falls and accumulates directly, affecting subsequent grinding work.

[0011] Preferably, a diffuser plate is fixedly connected to the end of the air outlet pipe; the diffuser plate has a trumpet-shaped structure. When air is injected into the air supply pipe, the air is sprayed out through the air outlet pipe. At this time, the air is dispersed under the action of the diffuser plate. By fixing a diffuser plate to the end of the air outlet pipe, the gas can be diffused when the gas is sprayed out of the air outlet pipe, which can increase the contact area between the air and the grinding roller, thereby enhancing the cleaning effect of the air on the surface of the grinding roller.

[0012] Preferably, a cover plate is hinged to the diffuser plate; the cover plate is located between the diffuser plate and the grinding roller. When gas passes through the diffuser plate, the cover plate is pushed upward, and when the blowing stops, the cover plate moves downward to seal the diffuser plate. By fixing the cover plate to the diffuser plate, the diffuser plate can be sealed when the blowing stops, reducing the possibility of polyurethane raw materials entering the interior of the diffuser plate and accumulating, which could cause the diffuser plate to become blocked.

[0013] The utility model is beneficial in that:

[0014] 1. The raw material grinding device of this utility model has an air supply pipe running through the side wall of the box, an air supply box connected to the end of the air supply pipe, and multiple air outlet pipes connected to the air supply box. During the grinding process, air is injected into the air supply pipe and blown towards the surface of the grinding roller. This can clean the polyurethane raw material adhering to the surface of the grinding roller during the grinding process, reducing the situation where polyurethane raw material adheres to the surface of the grinding roller, resulting in incomplete grinding of polyurethane by the grinding roller.

[0015] 2. The raw material grinding device of this utility model has a guide plate fixed to the inner side wall of the box, and multiple diverter plates fixed to the guide plate. This can guide the raw material when it is placed inside the box, and at the same time reduce the situation where the raw material falls to the surface of the air box and cannot be ground when it is placed inside the box.

[0023] 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 scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a raw material grinding device includes a housing 1; two sets of motors 11 are fixedly connected to the middle of the housing 1; a connecting shaft 12 is fixedly connected to the output end of the motor 11; the connecting shaft 12 and the housing 1 are through-connected and rotatably connected; a grinding roller 13 is fixedly connected to the end of the connecting shaft 12; a pair of air supply pipes 14 are through-connected to the side wall of the housing 1; the end of the air supply pipe 14 is connected to an air supply box 15; multiple air outlet pipes 16 are fixedly connected to the air supply box 15; the air outlet pipes 16 and the air supply pipes 14 are connected. When working, the motor 11 is turned on, and then polyurethane raw material is placed into the housing 1 from the inlet. When the motor 11 is turned on, it drives the connecting shaft 12 fixedly connected to its output end to rotate. The rotation of the connecting shaft 12 drives the grinding roller 13 to rotate simultaneously. The grinding roller 13 grinds the polyurethane raw material. When grinding the polyurethane raw material, air is injected into the air supply pipe 14. The gas enters the air supply box 15 through the air supply pipe 14 and is then ejected from the air outlet pipe 16 fixed to the air supply box 15. The ejected air blows towards the surface of the grinding roller 13 to clean the surface of the grinding roller 13. By providing the air supply pipe 14 through the side wall of the housing 1, and connecting the end of the air supply pipe 14 to the air supply box 15, and connecting multiple air outlet pipes 16 on the air supply box 15, air is injected into the air supply pipe 14 during the grinding process and blown towards the surface of the grinding roller 13. This can clean the polyurethane raw material adhering to the surface of the grinding roller 13 during the grinding process, reducing the situation where the polyurethane raw material adheres to the surface of the grinding roller 13 and causes the grinding roller 13 to not grind the polyurethane thoroughly.

[0026] like Figure 2 As shown, a pair of guide plates 2 are fixed to the inner wall of the housing 1; multiple flow dividers 21 are fixed to the surface of the guide plates 2; when the polyurethane raw material is placed inside the housing 1, the raw material passes over the surface of the guide plates 2, and when the raw material passes between the multiple flow dividers 21, the flow dividers 21 guide the raw material to the space between a pair of grinding rollers 13 for better grinding. By fixing the guide plates 2 to the inner wall of the housing 1 and fixing multiple flow dividers 21 to the guide plates 2, the raw material can be guided when it is placed inside the housing 1, and the situation where the raw material falls onto the surface of the gas delivery box 15 and cannot be ground can also be reduced when the raw material is placed inside the housing 1.

[0027] like Figure 3As shown, a plurality of first striking blocks 3 are fixedly connected to the connecting shaft 12; a second striking block 31 is fixedly connected to the surface of the guide plate 2; the first striking blocks 3 and the second striking blocks 31 are arranged correspondingly. When the connecting shaft 12 rotates, the first striking blocks 3 also rotate. The rotating first striking blocks 3 and the second striking blocks 31 come into contact and strike the second striking blocks 31. When the first striking blocks 3 strike the second striking blocks 31, the vibration is transmitted to the surface of the guide plate 2 through the second striking blocks 31. By fixing a plurality of first striking blocks 3 to the connecting shaft 12 and fixing a second striking block 31 to the surface of the guide plate 2, the rotating first striking blocks 3 can strike the second striking blocks 31, which can reduce the accumulation of polyurethane raw materials on the surface of the guide plate 2 when the polyurethane raw materials are placed inside the box 1.

[0028] like Figure 4 As shown, a pair of connecting blocks 4 are fixed to the inner side wall of the box 1; a dispersing plate 41 is fixed between the pair of connecting blocks 4. When the polyurethane raw material is ground by the grinding roller 13, it falls onto the surface of the dispersing plate 41. At this time, the ground raw material slides from the surface of the dispersing plate 41 to both sides. By fixing the dispersing plate 41 between the pair of connecting blocks 4, the polyurethane pigment after grinding can be dispersed, reducing the situation where the ground polyurethane raw material falls directly and accumulates, affecting subsequent grinding work.

[0029] like Figure 5 As shown, a diffuser plate 5 is fixedly connected to the end of the air outlet pipe 16. The diffuser plate 5 has a trumpet-shaped structure. When air is injected into the air supply pipe 14, the air is sprayed out through the air outlet pipe 16. At this time, the air is dispersed under the action of the diffuser plate 5. By fixing the diffuser plate 5 to the end of the air outlet pipe 16, the gas can be diffused when the gas is sprayed out of the air outlet pipe 16, which can increase the contact area between the air and the grinding roller 13, thereby enhancing the cleaning effect of the air on the surface of the grinding roller 13.

[0030] like Figure 5 As shown, a cover plate 6 is hinged to the diffuser plate 5; the cover plate 6 is located between the diffuser plate 5 and the grinding roller 13. When gas passes through the diffuser plate 5, the cover plate 6 is pushed upward. When the blowing stops, the cover plate 6 moves downward to seal the diffuser plate 5. By fixing the cover plate 6 to the diffuser plate 5, the diffuser plate 5 can be sealed when the blowing stops, reducing the possibility of polyurethane raw materials entering the interior of the diffuser plate 5 and accumulating, which could cause the diffuser plate 5 to become blocked.

[0031] Working principle: The motor 11 is turned on, and then the polyurethane raw material is placed into the housing 1 through the inlet. When the motor 11 is turned on, it drives the connecting shaft 12 fixed to its output end to rotate. Simultaneously, the rotating connecting shaft 12 drives the grinding roller 13 to rotate. The rotating grinding roller 13 grinds the polyurethane raw material. During the grinding process, air is injected into the air supply pipe 14. The gas enters the air supply box 15 through the air supply pipe 14 and is then ejected from the air outlet pipe 16 fixed to the air supply box 15. The ejected air blows towards the grinding roller 13. The surface of the grinding roller 13 is cleaned. When the polyurethane raw material is put into the housing 1, the material slides across the surface of the guide plate 2. When the material passes between multiple diverter plates 21, the diverter plates 21 guide the material to the pair of grinding rollers 13 for better grinding. When the connecting shaft 12 rotates, the first striking block 3 also rotates. The rotating first striking block 3 contacts the second striking block 31 and strikes the second striking block 31. When the first striking block 3 strikes the second striking block 31, the vibration is transmitted through the second striking block 31. When the polyurethane raw material is ground by the grinding roller 13, it falls onto the surface of the dispersion plate 41. At this time, the ground raw material slides from the surface of the dispersion plate 41 to both sides. By fixing the dispersion plate 41 between a pair of connecting blocks 4, the ground polyurethane pigment can be dispersed, reducing the situation where the ground polyurethane raw material falls directly and accumulates, affecting subsequent grinding work. When air is injected into the air supply pipe 14, the air is sprayed out through the air outlet pipe 16. At this time, the air is dispersed under the action of the diffuser plate 5. By fixing the diffuser plate 5 at the end of the air outlet pipe 16, the gas can be diffused when the gas is sprayed out of the air outlet pipe 16, which can increase the contact area between the air and the grinding roller 13, thereby enhancing the cleaning effect of the air on the surface of the grinding roller 13. When the gas passes through the diffuser plate 5, the cover plate 6 is pushed upward. When the blowing stops, the cover plate 6 moves downward to seal the diffuser plate 5. By fixing the cover plate 6 on the diffuser plate 5, the diffuser plate 5 can be sealed when the blowing stops, reducing the situation where the polyurethane raw material enters the interior of the diffuser plate 5 and accumulates, causing the diffuser plate 5 to become blocked.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
