Description

Technical Field

[0001] The utility model relates to the technical field of chemical machinery, in particular to a three-roll grinder for processing paste-like gels. Background Art

[0002] The three-roll grinder is the most effective grinding and dispersing equipment for high-viscosity materials. Its principle is to achieve the grinding effect through the mutual extrusion of the surfaces of three horizontal rollers and the friction at different speeds. The three-roll grinder is mainly used for grinding various liquid slurries and paste-like materials such as paints, inks, pigments, plastics, cosmetics, soaps, ceramics, and rubbers.

[0003] When processing paste-like gels with a three-roll grinder, the paste-like gels are poured between the grinding rollers of the three-roll grinder through a hopper. Since the grinding rollers of the three-roll grinder have a certain length, and the discharge port of the hopper is relatively small compared to the length of the grinding rollers, the paste-like gels poured on the three-roll grinder will accumulate concentratedly. The paste-like gels poured on the grinding rollers cannot be evenly and effectively dispersed, resulting in uneven shear force and friction force on the paste-like gels during the grinding process, and further causing the problem of low grinding uniformity. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problem that the paste-like gel materials poured during the grinding of paste-like gels by the existing three-roll grinder cannot be evenly dispersed on the grinding rollers, resulting in uneven shear force and friction force on the paste-like gels during the grinding process, and further causing the problem of low grinding uniformity, and to propose a three-roll grinder for processing paste-like gels.

[0005] To achieve the above purpose, the utility model adopts the following technology: A three-roll grinder for processing paste-like gels, including a frame, a grinding roller is arranged on the frame, a feeding hopper that reciprocates along the length direction of the grinding roller is arranged on the top of the frame through a driving component, the discharge port of the feeding hopper is located above the grinding roller, a heating component is arranged on the feeding hopper, a discharge plate is fixedly installed on the front side of the frame, and a base is arranged at the bottom of the frame.

[0006] As a further description of the above technical solution: The driving component includes a bracket fixed on the top of the frame, a screw rod is arranged on the bracket through a motor, and a sliding seat that is threadedly matched with the screw rod is arranged on the screw rod;

[0007] The feeding hopper is connected to the sliding seat.

[0008] As a further description of the above technical solution: A fixed sleeve is fixedly installed on one side of the sliding seat close to the feeding hopper, and an insertion plate that is matched with the fixed sleeve is arranged on the outer side of the feeding hopper through a mounting plate;

[0009] The feeding hopper is detachably connected to the sliding seat through the cooperation of the plug board and the fixed sleeve.

[0010] As a further description of the above technical solution: an installation groove is formed on the plug board, and a limiting block abutted against the bottom of the fixed sleeve is arranged on the installation groove, and a spring is arranged between the limiting block and the inner wall of the installation groove.

[0011] As a further description of the above technical solution: the limiting block is wedge-shaped, and a pair of handles is arranged on the feeding hopper near the top thereof.

[0012] As a further description of the above technical solution: the heating component includes a mounting seat detachably mounted on the feeding hopper through a fixing plate, a wiring head is arranged at one end of the mounting seat, and an electric heating tube electrically connected to the wiring head is arranged inside the mounting seat.

[0013] As a further description of the above technical solution: the number of the electric heating tubes is several and they are uniformly arranged in the mounting seat along the width direction thereof.

[0014] As a further description of the above technical solution: a baffle for controlling the flow of the paste is arranged on the frame at a position above the grinding roller.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0017] 2. By arranging a heating component on the feeding hopper, it is possible to heat the paste-like gel with higher hardness or viscosity during grinding, thereby reducing its hardness and viscosity and making it easier to grind the paste-like gel with higher hardness or viscosity.

Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0027] Refer to Figures 1-6 , a three-roll grinding machine for paste-like gel processing provided in this embodiment includes a frame 1, a grinding roller 2 is arranged on the frame 1, a feeding hopper 4 that reciprocates along the length direction of the grinding roller 2 is arranged on the top of the frame 1 through a driving assembly 3, the discharge port of the feeding hopper 4 is located above the grinding roller 2, a heating assembly 5 is arranged on the feeding hopper 4, a discharge plate 6 is fixedly installed on the front side of the frame 1, and a base 8 is arranged at the bottom of the frame 1.

[0028] In the present utility model, the frame 1 is stably placed through the base 8. When it is necessary to process the paste-like gel, the paste-like gel is first put into the feeding hopper 4. The feeding hopper 4 reciprocates along the length direction of the grinding roller 2 under the driving action of the driving assembly 3. During the reciprocating movement of the feeding hopper 4, the paste-like gel in the feeding hopper 4 can be evenly distributed on the grinding roller 2. The power mechanism on the frame 1 drives the grinding roller 2 to rotate, so that the paste-like gel is subjected to uniform shear force and friction force during the grinding process, improving the uniformity of grinding. The ground material is discharged through the discharge plate 6;

[0029] When the paste gel to be processed has a high hardness or a high viscosity, the paste gel with a high hardness or a high viscosity is heated by the heating component 5 on the feeding hopper 4, thereby reducing its hardness and viscosity, making the paste gel with a high hardness or a high viscosity easier to grind;

[0030] It should be noted that the power mechanism on the frame 1 drives the grinding roller 2 to rotate using the existing commonly used three-roller grinding machine driving method, so it will not be described in detail.

[0031] Specifically, Figure 2 and Figure 3 As shown, the driving assembly 3 includes a bracket 31 fixed on the top of the frame 1, a screw 33 is arranged on the bracket 31 through a motor 32, a slide seat 34 matched with its thread is arranged on the screw 33, and the feeding hopper 4 is connected to the slide seat 34.

[0032] Among them, the bracket 31 is fixed to the top of the frame 1 by fasteners, and the motor 32 on the bracket 31 drives the screw 33 to rotate, and then the slide 34 on the screw 33 that cooperates with its thread will move linearly on the screw 33, and the feeding hopper 4 is connected to the slide 34, so that the feeding hopper 4 can be driven to move when the slide 34 moves. As the feeding hopper 4 moves, the paste gel in the feeding hopper 4 will fall evenly on the grinding roller 2, ensuring that the paste gel can be evenly ground.

[0033] Specifically, Figures 2-4 As shown, a fixing sleeve 35 is fixedly installed on one side of the slide seat 34 close to the feeding hopper 4, and a plug plate 41 matching with the fixing sleeve 35 is provided on the outer side of the feeding hopper 4 through a mounting plate 42;

[0034] The feeding hopper 4 is detachably connected to the sliding seat 34 through the cooperation between the insert plate 41 and the fixing sleeve 35 .

[0035] Among them, when the feeding hopper 4 is connected with the slide seat 34, the feeding hopper 4 is installed from top to bottom so that the plug plate 41 of the feeding hopper 4 is aligned with the fixed sleeve 35 of the slide seat 34. As the feeding hopper 4 descends, the L-shaped plug plate 41 is inserted into the fixed sleeve 35, and then the top of the plug plate 41 is against the top of the fixed sleeve 35, so that the feeding hopper 4 and the slide seat 34 are connected. When the feeding hopper 4 needs to be cleaned or repaired, the feeding hopper 4 is lifted up to make the plug plate 41 detach from the fixed sleeve 35, which facilitates the installation and disassembly of the feeding hopper 4 and the slide seat 34.

[0036] Specifically, Figure 2 and Figure 5 As shown, a mounting groove 411 is formed on the plug plate 41 , and a limiting block 412 is disposed on the mounting groove 411 to abut against the bottom of the fixing sleeve 35 , and a spring 413 is disposed between the limiting block 412 and the inner wall of the mounting groove 411 .

[0037] Among them, when the insertion plate 41 is inserted into the fixed sleeve 35, the limiting block 412 compresses the spring 413 and is squeezed in the installation groove 411. After the insertion plate 41 is completely inserted into the fixed sleeve 35, the limiting block 412 pops out under the action of the spring 413 and abuts against the bottom of the fixed sleeve 35, thereby realizing the limit of the insertion plate 41 and the fixed sleeve 35 in the longitudinal direction, avoiding the separation of the feeding hopper 4 and the sliding seat 34 caused by the shaking of the feeding hopper 4 in the longitudinal direction, and improving the connection stability between the feeding hopper 4 and the sliding seat 34.

[0038] It should be noted that the limiting block 412 is wedge-shaped, and a pair of handles 43 are arranged at a position near the top of the feeding hopper 4. The wedge-shaped limiting block 412 can facilitate the extrusion of the limiting block 412 in the installation groove 411 when the insertion plate 41 is inserted. When disassembling the feeding hopper 4, the operator only needs to squeeze the limiting block 412 by hand, and there is no need to manually squeeze the limiting block 412 when installing the feeding hopper 4. The handle 43 can facilitate the operator's grip and can quickly and conveniently remove the feeding hopper 4 when the feeding hopper 4 needs to be disassembled.

[0039] Specifically, as Figure 2 and Figure 6 shown, the heating component 5 includes a mounting seat 51 detachably mounted on the feeding hopper 4 through a fixing plate 54. One end of the mounting seat 51 is provided with a wiring head 52, and an electric heating tube 53 electrically connected to the wiring head 52 is arranged inside the mounting seat 51. The number of electric heating tubes 53 is several and they are evenly arranged along the width direction of the mounting seat 51.

[0040] Among them, the wiring head 52 is connected to an external power supply line. When it is necessary to grind a paste-like gel with a relatively high hardness or viscosity, the electric heating tube 53 in the mounting seat 51 is used to heat the paste-like gel in the feeding hopper 4, thereby reducing its hardness and viscosity and making it easier to grind the paste-like gel with a relatively high hardness or viscosity.

[0041] Specifically, as Figure 1 shown, a baffle 7 for controlling the flow of the paste is arranged at a position above the grinding roller 2 on the frame 1. The baffle 7 is located in the feeding direction. By adjusting the position or angle of the baffle 7, the feeding speed and flow rate of the material can be controlled to ensure that the material can enter the grinding area evenly and stably, thereby improving the grinding efficiency and effect.

[0042] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
