Description

Technical Field

[0001] This utility model relates to the field of grease grinding technology, and in particular to a grinding device for grease processing. Background Technology

[0002] In the production process of grease, the grinding process is crucial. Its purpose is to fully disperse solid components such as thickeners, prevent particle agglomeration, and thus ensure the colloidal stability of the grease, thereby improving the performance and quality of the grease.

[0003] In existing technologies, grease grinding is typically accomplished using a three-roll mill. During grinding, continuous filling is required in the filling zone to ensure grinding continuity and effectiveness. However, high-viscosity greases, with their high viscosity and poor flowability, easily adhere to the inner wall of the container and have a low natural flow rate. When using traditional container-pouring methods for feeding, it is difficult to precisely control the feeding amount, easily resulting in over- or under-feeding, affecting production efficiency. While manual feeding can alleviate issues like material accumulation to some extent, it requires dedicated personnel, undoubtedly wasting human resources, increasing production costs, and making it difficult to guarantee the stability and consistency of feeding, thus affecting the quality and efficiency of grease grinding. Utility Model Content

[0004] In order to overcome the shortcomings of the above-mentioned background technology, the present invention provides a grinding device for processing grease that can automatically and accurately feed grease and is suitable for high viscosity grease.

[0005] The technical solution is as follows: A grinding device for processing grease includes a grinding machine and a hopper disposed above the feed inlet of the grinding machine. The width of the hopper gradually narrows from top to bottom. A feed inlet is opened on its top surface and a discharge outlet is opened on its bottom surface. A pair of relatively rotating rollers are horizontally disposed above the discharge outlet, and both ends of the rollers are rotatably connected to the hopper. One of the rollers is driven by a reduction motor. A gap is formed between the two rollers. A filler plate is disposed directly above the gap. The width of the filler plate is smaller than the width of the gap. The filler plate is slidably connected to the hopper. The hopper is provided with a driving mechanism for driving the filler plate to make linear reciprocating motion in the vertical direction. A cutting plate and a pressing component are respectively disposed on opposite sides of the filler plate. The cutting plate moves relative to the inner wall of the hopper and cooperates with the inner wall of the hopper to cut the grease raw material.

[0006] Preferably, the driving mechanism includes a push rod, a spring, and a cam. The push rod is vertically arranged, with its upper end slidably connected to the hopper via a bracket, and its middle part fixedly connected to the side of the packing plate via a bracket. The hopper has a vertical hole adapted to the bracket. The spring is fitted onto the push rod and located between the bracket and the bracket. The cam is rotatably arranged on one side of the hopper and located directly below the push rod. The side of the cam abuts against the lower end of the push rod, and the cam is drivenly connected to one of the rotating rollers.

[0007] Preferably, the cutting plate includes a plate body, which is parallel to the packing plate. A plurality of vertical sliding rods are provided at the upper end of the plate body. Each vertical sliding rod is fitted with a second spring and a horizontal support. The second spring is located between the horizontal support and the plate body. One end of the horizontal support is fixed to the packing plate.

[0008] Preferably, the pressing member includes a pressing foot and a support arm, the lower end of which is connected to the pressing foot and the upper end of which is connected to the end of the horizontal support away from the packing plate.

[0009] Preferably, the horizontal support has a straight adjustment hole, and the support arm is adjustablely mounted in the straight adjustment hole by bolts.

[0010] Preferably, the lower end of the plate body is bent toward the packing plate side.

[0011] Preferably, the hopper, plate body, and presser foot are all made of stainless steel.

[0012] Preferably, the equipment also includes a feeding plate, which is located below the discharge port of the grinding machine. A crossbeam is provided at the bottom of the feeding plate, and support members are provided at both ends of the crossbeam. An adjustment groove and a crossbeam support are formed on the support member. An adjustment bolt is provided in the adjustment groove. One end of the adjustment bolt is set on the frame of the grinding machine, and the end of the support member rests on the crossbeam support.

[0013] The beneficial effects of this invention are as follows: The narrowed structure of the hopper facilitates the flow of grease towards the outlet. Combined with the relatively rotating rollers, this accelerates grease feeding and overcomes its high viscosity and flow resistance. Under the action of the drive mechanism, the packing plate pushes the viscous grease into the gaps, achieving stable feeding. The cutter cuts the grease to achieve quantitative feeding and avoids blockages. The lower pressure component, in conjunction with the packing plate, presses the grease to ensure smooth entry into the gaps. This device improves the efficiency and stability of the grinding machine, achieves automated feeding, and saves manpower. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0020] like Figure 1-4 The grease-processing grinding device shown mainly consists of a grinding mill 1 and a hopper 2 located above its inlet. The grinding mill 1 is a three-roll grinding mill. The width of the hopper 2 gradually narrows from top to bottom, which facilitates the smooth flow and centralized processing of the grease material. The top surface of the hopper 2 has an inlet 21 for inputting the material, and the bottom surface has an outlet 22. Above the outlet 22, a pair of relatively rotating rollers 3 are horizontally arranged. The two ends of the rollers 3 are rotatably connected to the hopper 2. Each of the two rollers 3 is equipped with a gear 32, and the two gears 32 mesh to drive each other. One of the rollers 3 is connected to a reduction motor 31, which drives the roller 3 to rotate relative to each other. A gap is formed between the rollers 3 for the grease material to enter the grinding mill 1. The relatively rotating rollers 3 can accelerate the flow of grease.

[0021] Furthermore, it should be noted that a filler plate 4 is installed directly above the gap, with a width smaller than the gap width. The left and right ends of the filler plate 4 are slidably connected to the hopper 2. The hopper 2 is equipped with a drive mechanism that drives the filler plate 4 to perform linear reciprocating motion in the vertical direction. The drive mechanism can be a cylinder, electric cylinder, or reciprocating slide table, etc. A cutting plate 5 and a pressing component 6 are respectively installed on opposite sides of the filler plate 4. The cutting plate 5 moves relative to the inner wall of the hopper 2, working in conjunction with the inner wall to cut the lubricating grease material, achieving segmented and quantitative feeding, avoiding blockage, improving the grinding efficiency and accuracy of the grinder, and ensuring feeding stability.

[0022] In one specific embodiment, the cutting plate 5 consists of a plate body 51, vertical sliding rods 52, springs 53, and a horizontal support 9. The plate body 51 is parallel to the packing plate 4, and multiple vertical sliding rods 52 are provided at the upper end. Each vertical sliding rod 52 is fitted with a spring 53 and a horizontal support 9. The spring 53 is located between the horizontal support 9 and the plate body 51, and one end of the horizontal support 9 is fixed to the packing plate 4. When the packing plate 4 reciprocates, the cutting plate 5 abuts against the hopper 2, causing the vertical sliding rods 52 to slide relative to the horizontal support 9. After the two disengage, they are driven to return to their original positions by the springs 53. Therefore, the movement of the plate body 51 is buffered and stable by means of the vertical sliding rods 52 and springs 53, which not only achieves precise segmented and quantitative feeding, but also effectively avoids the clogging problem caused by the continuity of grease, improves the grinding efficiency and accuracy of the grinder 1, and ensures the stability and reliability of the feeding process.

[0023] refer to Figure 2 and Figure 3 The lower pressure component 6 specifically includes a pressure foot 61 and a support arm 62. The lower end of the support arm 62 is connected to the pressure foot 61, and the upper end is connected to the end of the horizontal bracket 9 away from the filler plate 4. When the filler plate 4 pushes the grease to feed, the side of the lower pressure component 6 works in conjunction with the filler plate 4 to press the grease, increasing the force and preventing local obstruction of high-viscosity grease feeding, ensuring smooth grease entry into the gaps, and improving feeding reliability. The horizontal bracket 9 has a straight adjustment hole 91, and the support arm 62 can be adjusted in the hole by bolts. According to production needs and grease characteristics, the position of the lower pressure component 6 can be flexibly adjusted to enhance the versatility and applicability of the device, meet the grinding needs of greases with different viscosities and formulations, and improve the flexibility and practicality of the device.

[0024] In a preferred embodiment, the lower end of the plate body 51 is bent toward the packing plate 4, which facilitates the guidance of lubricating grease to the gap during cutting and pushing, improving feeding efficiency, and preventing the cutting edge of the plate body 51 from colliding with the side wall of the hopper 2 and causing damage to both. Furthermore, the hopper 2, plate body 51, and pressure foot 61 are made of stainless steel, which has good corrosion resistance and wear resistance, adapts to complex grinding environments, and has strong anti-sticking properties.

[0025] like Figure 2As shown, the drive mechanism includes a push rod 71, a spring 72, and a cam 73. The push rod 71 is a round rod arranged vertically. Its upper end is slidably connected to the hopper 2 via a bracket 74, and its middle part is fixedly connected to the side of the filler plate 4 via a bracket 75. The hopper 2 has a vertical hole 23 adapted to the bracket 75. One side of the bracket 75 passes through the vertical hole 23 and is fixed to the filler plate 4. The spring 72 is sleeved on the push rod 71 and is located between the bracket 74 and the bracket 75. The spring 72 is a high-strength spring and is the power source for pressing down the filler plate 4. The cam 73 is rotatably mounted on one side of the hopper 2, located directly below the push rod 71. The side of the cam 73 abuts against the lower end of the push rod 71 and is connected to one of the rotating rollers via a belt pulley. When the rotating roller 3 rotates, the cam 73 rotates, driving the filler plate 4 to move vertically back and forth via the push rod 71 and the spring 72, ensuring that the lubricating grease material is pushed and cut rhythmically.

[0026] like Figure 1 and Figure 4 As shown, this device is also equipped with a feeding plate 8, which is located below the discharge port of the grinding machine 1. A crossbeam 81 is located at the bottom of the feeding plate 8, and support members 82 are located at both ends of the crossbeam 81. The support members 82 have an adjustment groove 821 and a crossbeam support portion 822. An adjustment bolt 83 is installed in the adjustment groove 821. One end of the adjustment bolt 83 is fixed to the frame of the grinding machine 1, and the end of the support member 82 rests on the crossbeam support portion 822. This structure allows for flexible adjustment of the height and position of the feeding plate 8, facilitating coordination with subsequent processes or collection devices, improving production continuity and automation, and facilitating the collection and treatment of lubricating grease after grinding, thus increasing the practicality of the device. Furthermore, multiple tension springs 84 are located on the back of the feeding plate 8 near the discharge port of the grinding machine 1. One end of the tension spring is connected to the back of the feeding plate 8, and the other end is connected to the frame of the grinding machine 1. Through the action of the tension springs 84, the upper end of the feeding plate 8 can be pressed against the discharge port of the grinding machine 1, improving the discharge efficiency.
