Description

Technical Field

[0001] This utility model relates to the field of grinding mills, and in particular to an adjustable blade holder for grinding mills. Background Technology

[0002] A grinding mill is an important type of pulverizing equipment, widely used in food processing, chemical industry, building materials, and many other fields. Its main function is to grind materials to the required fineness to meet diverse production needs. A grinding mill typically consists of a drive unit, a grinding unit, and a collection unit, with the grinding unit being the core component responsible for crushing and grinding the materials. With continuous technological advancements, the performance and efficiency of grinding mills are constantly improving, providing strong support for production in various industries.

[0003] The tool holder on the grinding mill is an important component. It is mainly used to fix and coordinate the cutting tools, ensuring that the tools can perform efficient and precise machining in the appropriate position. The tool holder can fix the appropriate tool length, weight and cutting performance, thereby improving the rigidity of the tool and avoiding excessive deformation during the machining process, thus improving cutting accuracy and machining efficiency.

[0004] Traditional grinding mill blade holders are usually designed with a fixed shape, meaning that the position and extension length of the blades are not adjustable. When changing different blades, corresponding extension parts need to be installed, and the blades need to be constantly adjusted after installation to ensure that the distance between each blade and the blade holder is consistent. Otherwise, if the gap between the blade and the fixed blade is too large, the grinding efficiency will be reduced. Utility Model Content

[0005] In order to overcome the shortcomings of existing technical solutions, this utility model provides an adjustable blade holder for a grinding mill, which can effectively solve the technical problem of complex blade adjustment.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] An adjustable blade holder for a grinding mill includes a frame and several blade holders. The blade holders are used to mount blades. The blade holders are evenly distributed around the axis of the frame on the side wall of the frame. The frame is provided with positioning grooves that match the blade holders. The blade holders are installed in the positioning grooves and can move along the positioning grooves. One end of the blade holder for mounting the blade extends out of the frame. An adjusting turntable is provided inside the blade holder. The adjusting turntable is rotatably mounted in the blade holder and its rotation axis coincides with the axis of the blade holder. A positioning sleeve is provided on the inner wall of the blade holder. A drive shaft is provided on the adjusting turntable and passes through the adjusting turntable. One end of the drive shaft is inserted into the positioning sleeve. The adjusting turntable is provided with a raised guide rail. The blade holders are provided with slots that match the guide rail. The drive shaft can drive the adjusting turntable to rotate clockwise or counterclockwise. When the adjusting turntable rotates, it drives the blade holders to move in the positioning grooves through the guide rails and slots, thereby adjusting the length of the blade holders extending out of the frame.

[0008] Furthermore, the tool holder is provided with a turntable groove at one end near the adjusting turntable, the edge of the adjusting turntable can be inserted into the turntable groove, a slot is provided on the side wall of the turntable groove, and a guide rail is provided on the front of the adjusting turntable.

[0009] Furthermore, the guide rail extends in a spiral shape, and each tool holder is provided with several evenly arranged slots, each slot engaging with multiple sections of the guide rail in the radial direction of the turntable slide.

[0010] Furthermore, the surface of the frame is provided with a rotating sleeve that coincides with the axis, and the end of the drive shaft away from the positioning sleeve passes through the rotating sleeve. The surface of the rotating sleeve is provided with a ring of drive teeth for connecting the grinding mill drive assembly.

[0011] Furthermore, the two ends of the drive shaft are rotatably connected to the rotating sleeve and the positioning sleeve respectively via bearings.

[0012] Furthermore, the tool holder is provided with a guide limit strip for easy installation and positioning, and the side wall of the guide limit strip is slidably connected to the surface of the frame.

[0013] Furthermore, the adjusting turntable is provided with a limiting boss, and the side wall of the limiting boss is provided with a buffer pad.

[0014] Compared with existing technologies, the advantages of this invention are as follows: By designing a positioning groove and a movable blade holder along it, along with a matching adjustment turntable and guide rail, the length of the blade holder extending out of the frame is flexibly adjustable. This design not only allows the blade holder to be precisely adjusted according to different grinding requirements, but also ensures that the installed blades can closely cooperate with the fixed blades of the mill, avoiding poor grinding effects or equipment malfunctions caused by excessive gaps. The blade holder can be controlled to extend and retract according to actual grinding requirements by rotating the adjustment turntable. When the adjustment turntable rotates, the guide rail slides in the slot, thereby causing the blade holder to extend and retract relative to the blade holder along the positioning groove. This ensures that each blade holder extends and retracts synchronously, making it easier to adjust the blade extension length without the need for individual adjustment of each blade holder. When it is necessary to disassemble the blade, the blade holder can be quickly retracted by adjusting the turntable to separate the blade from the fixed blade, making disassembly more convenient.

[0020] 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 protection scope of the present utility model.

[0021] The following is combined with Figures 1-4 This invention provides a detailed description of an adjustable blade holder for a grinding mill:

[0022] An adjustable blade holder for a grinding mill includes a frame 1 and several blade holders 2. The blade holders 2 are used to mount blades. The blade holders 2 are evenly distributed around the axis of the frame 1 on the side wall of the frame 1. The frame 1 is provided with positioning grooves 101 that match the blade holders 2. The blade holders 2 are installed in the positioning grooves 101 and can move along the positioning grooves 101. One end of the blade holder 2 for mounting the blade extends outward from the outside of the frame 1. An adjusting turntable 3 is provided inside the blade holder. The adjusting turntable 3 is rotatably mounted in the blade holder, and its rotation axis coincides with the axis of the blade holder. The tool holder has a positioning sleeve 102 on its inner wall. The adjustment turntable 3 has a drive shaft 4 that passes through it. One end of the drive shaft 4 is inserted into the positioning sleeve 102. The adjustment turntable 3 has a raised guide rail 301. The tool holder 2 has a matching slot 203. The drive shaft can drive the adjustment turntable 3 to rotate clockwise or counterclockwise. When the adjustment turntable 3 rotates, it drives the tool holder 2 to move in the positioning groove 101 through the guide rail 301 and the slot 203, thereby adjusting the length of the tool holder 2 extending out of the frame 1.

[0023] By designing a positioning slide 101 and a movable blade holder 2 along it, along with a matching adjusting turntable 3 and guide rail 301, the length of the blade holder 2 extending out of the frame 1 is flexibly adjustable. This design not only allows the blade holder 2 to be precisely adjusted according to different grinding requirements, but also ensures that the installed blades can closely cooperate with the fixed blades of the mill, avoiding poor grinding effect or equipment failure caused by excessive gaps. The blade holder 2 can be controlled to extend and retract according to actual grinding requirements by rotating the adjusting turntable 3. When the adjusting turntable 3 rotates, the guide rail 301 slides in the slot 203, thereby allowing the blade holder 2 to extend and retract relative to the blade holder along the positioning slide 101. This ensures that each blade holder 2 extends and retracts synchronously, making it easier to adjust the extension length of the blades without the need for individual adjustment of each blade holder 2. When it is necessary to disassemble the blades, the blade holder 2 can be quickly retracted by adjusting the turntable 3 to separate the blades from the fixed blades, making disassembly more convenient.

[0024] The tool holder 2 has a turntable groove 202 at one end near the adjusting turntable 3. The edge of the adjusting turntable 3 can be inserted into the turntable groove 202. A retaining groove 203 is provided on the side wall of the turntable groove 202, and a guide rail 301 is provided on the front of the adjusting turntable 3, enhancing the connection stability between the tool holder 2 and the adjusting turntable 3. The turntable groove 202 ensures that the adjusting turntable 3 can more firmly drive the tool holder 2 when rotating, avoiding inaccurate adjustment or tool holder 2 wobbling caused by loose connection, thus improving stability and durability.

[0025] The guide rail 301 extends in a spiral shape, and each tool holder 2 is provided with several evenly arranged slots 203. Each slot 203 engages with multiple sections of guide rail 301 in the radial direction of the turntable slide groove 202, thereby improving the stability and accuracy of the tool holder 2 during the adjustment process.

[0026] The surface of the frame 1 is provided with a rotating sleeve 5 that coincides with the axis. The end of the drive shaft 4 away from the positioning sleeve 102 passes through the rotating sleeve 5. The surface of the rotating sleeve 5 is provided with a ring of drive teeth for connecting the grinding mill drive assembly, so that the drive shaft 4 can be more stably supported on the frame 1. The two ends of the drive shaft 4 are rotatably connected to the rotating sleeve 5 and the positioning sleeve 102 respectively through bearings 6. The supporting and lubricating effect of the bearings 6 reduces friction and wear of the drive shaft 4 during rotation, thereby extending the service life of the equipment. At the same time, this design also allows the drive shaft 4 to transmit torque and rotation angle more accurately, ensuring the precise adjustment of the tool holder 2.

[0027] The tool holder 2 is provided with a guide limit strip 201 for easy installation and positioning. The side wall of the guide limit strip 201 is slidably connected to the surface of the frame 1, which makes the tool holder 2 more convenient and quick to install and position. It can ensure that the turntable slide 202 of the tool holder 2 can be aligned with the adjustment turntable 3 during the installation process, thereby improving the accuracy and stability of the installation.

[0028] The adjusting turntable 3 is provided with a limiting boss, and a buffer pad is provided on the side wall of the limiting boss. The limiting boss and the buffer pad serve to protect the tool holder and the adjusting turntable 3. When the adjusting turntable 3 rotates to its limit position, the limiting boss can prevent it from continuing to rotate and damaging the equipment. At the same time, the buffer pad also reduces the friction and impact between the limiting boss and the tool holder, thereby extending the service life of the equipment. This design improves the reliability and safety of the tool holder.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
