Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, and in particular to an adjustable angle stone grinding head structure. Background Technology

[0002] Adjustable angle stone grinding head structure is usually an optimized design based on traditional grinding heads. By adding an angle adjustment component, the grinding parts of the grinding head can flexibly adjust the tilt angle or rotation angle within a certain range according to processing requirements. This structure generally includes a drive mechanism, angle adjustment component, fixed base and some grinding unit parts. The angle adjustment method adopts manual knob, hydraulic drive or electric control, and precise angle positioning is achieved with scale marks or sensors. It can meet the grinding processing requirements of different edges, curved surfaces or bevels of stone, improve the adaptability and processing accuracy of equipment to diverse stone products, and is widely used in the field of stone processing machinery.

[0003] A search revealed a Chinese patent publication number: CN201446471U, which discloses a fully automatic stone edge grinding machine capable of producing high-quality products in an assembly line manner. This machine improves the processing efficiency and yield of high-grade stone, while reducing processing costs. The structure includes a conveying mechanism with input and output directions, a grinding mechanism, and a power mechanism. The grinding mechanism comprises a set of upward-facing edge grinding heads driven by the power mechanism. These grinding heads are arranged sequentially from the input direction to the output direction, with each head forming a certain angle with the stone's conveying direction. By sequentially grinding the stone with these heads, the process from coarse grinding to fine grinding can be completed in one pass. The angle between the grinding heads and the stone's conveying direction prevents the stone from hitting the sides of the grinding heads during transport, thus ensuring grinding quality. However, due to the varying shapes of the stones, some stones may not be able to be fixed in place, affecting processing efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an adjustable angle stone grinding head structure, which aims to improve the problem in the prior art that some stones cannot be fixed due to the different shapes of the stones, thus affecting the processing efficiency.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an adjustable-angle stone grinding head structure, comprising a body, a fixing mechanism installed on the top of the body for fixing the stone, a cleaning mechanism installed on the rear side of the top of the body for cleaning debris, the fixing mechanism comprising a vertical plate fixedly connected to the front side of the top of the body, a plurality of threaded rods threadedly connected at equal intervals in the middle of the vertical plate, a knob fixedly connected to the front side of the threaded rods, a U-shaped plate threadedly connected to the rear side of the threaded rods, a plurality of mounting blocks equidistantly arranged on the top of the body, fixing plates fixedly connected to the left and right sides of the top of each mounting block, a spring fixedly connected to the outer side of the fixing plate, and a clamping block fixedly connected to the outer side of the spring.

[0006] The above technical solution involves first placing the stone on the top mounting block of the machine body. The spring applies an initial clamping force to the clamping block through the fixing plate to initially fix the stone. Then, by rotating the knob in the middle of the upright plate, the threaded rod is rotated, causing the U-shaped plate, which is threaded to the rear end of the threaded rod, to move towards the stone. The U-shaped plate and the clamping block work together to adjust the clamping position and force according to the shape of the stone, thereby achieving stable fixation of stones of various shapes.

[0007] As a further description of the above technical solution: The cleaning mechanism includes an L-shaped plate, which is located at the top of the machine body. A connecting rope is located on the right side of the top of the machine body. A moving block is fixedly connected to the other end of the connecting rope. A fan is located on the front side of the moving block. An elastic rope is fixedly connected to the left side of the moving block. The other end of the elastic rope is fixedly connected to the left side of the L-shaped plate. A drive assembly is located on the outside of the connecting rope.

[0008] The above technical solution involves tightening the connecting rope to move the movable block. This stretches the elastic rope, causing the fan at the front end of the movable block 303 to move and activate, blowing away debris. When the motor stops or reverses, the elastic rope releases its stored elastic potential energy, pushing the movable block back to its original position, and the fan resumes its cleaning task. By adjusting the motor's operating state, the fan's reciprocating movement and multi-angle blowing are achieved, effectively preventing debris accumulation and ensuring that subsequent processing is not affected.

[0009] As a further description of the above technical solution: The drive assembly includes a motor, which is located on the top right side of the machine body, and the output end of the motor is fixedly connected to a rotating shaft.

[0010] The above technical solution involves a rotating shaft fixed at the output end of the motor, which will drive the rotating shaft to rotate.

[0011] As a further description of the above technical solution: A support plate is provided on the outer side of the machine body, and the front side of the support plate is fixedly connected to the rear side of the motor.

[0012] The above technical solution uses a support plate to support the motor.

[0013] As a further description of the above technical solution: The outer side of the body is provided with a threaded groove, which is located in the middle of the vertical plate.

[0014] The above technical solution involves providing threaded grooves on the upright plate.

[0015] As a further description of the above technical solution: Multiple rubber pads are provided in the middle of the body, and the rear side of the rubber pads is fixedly connected to the rear side of the inner wall of the U-shaped plate.

[0016] The above technical solution involves installing rubber pads on the U-shaped plate.

[0017] As a further description of the above technical solution: A support frame is fixedly connected to the bottom of the machine body, and mounting plates are fixedly connected to the four corners of the bottom of the support frame.

[0018] The above technical solution involves installing a support frame at the bottom of the machine body, and installing a mounting plate at the bottom of the support frame.

[0019] As a further description of the above technical solution: A sliding groove is provided on the outer side of the body, and the sliding groove is opened on the top of the L-shaped plate.

[0020] The above technical solution involves providing a sliding groove on the L-shaped plate.

[0021] This utility model has the following beneficial effects: 1. In this utility model, during the stone fixing process, the stone is first placed on the mounting block at the top of the machine body. The spring provides initial clamping force to the clamping block through the fixing plate. Then, the knob in the middle of the upright plate is turned to drive the threaded rod to rotate, so that the U-shaped plate moves towards the stone and works in conjunction with the clamping block to adjust the clamping position and force, so as to firmly fix stones of different shapes and meet the needs of complex stone processing.

[0022] 2. In this invention, the motor drives the shaft to rotate, the connecting rope tightens and pulls the moving block, the elastic rope extends, and the fan moves and turns on to remove debris. When the motor stops or reverses, the elastic rope releases energy, causing the moving block to reset, and the fan cleans again. Controlling the motor allows for the fan to move back and forth and blow at multiple angles, preventing debris accumulation from affecting processing. Attached Figure Description

Rotating the knob 203... 03 will drive the threaded rod 202 fixed thereto to rotate. The threaded rod 202 is threadedly connected to a U-shaped plate 204 on the rear side. Multiple mounting blocks 205 are equidistantly arranged on the top of the machine body 1. Fixing plates 206 are fixedly connected to the left and right sides of the top of the mounting blocks 205. Springs 207 are fixedly connected to the outside of the fixing plates 206. Clamping blocks 208 are fixedly connected to the outside of the springs 207. Threaded grooves 5 are provided on the outside of the machine body 1. The threaded grooves 5 are opened in the middle of the upright plate 201. The threaded grooves 5 allow the threaded rod 202 to slide on its inner wall. Specifically, during the stone fixing process, the stone is first placed on the top mounting block 205 of the machine body 1. The spring 207 applies an initial clamping force to the clamping block 208 through the fixing plate 206 to initially fix the stone. Then, by rotating the knob 203 in the middle of the vertical plate 201, the threaded rod 202 is rotated, causing the U-shaped plate 204, which is threaded to the rear end of the threaded rod 202, to move towards the stone. The U-shaped plate 204 and the clamping block 208 work together to adjust the clamping position and force according to the shape of the stone, thereby achieving stable fixing of stones of various shapes and meeting the needs of processing complex-shaped stones. The outer side of the machine body 1 is provided with a threaded groove 5, which is located in the middle area of ​​the vertical plate 201, allowing the threaded rod 202 to slide in it.

[0027] Reference Figure 2 , Figure 3 and Figure 5The cleaning mechanism 3 includes an L-shaped plate 301, which is located at the top of the body 1. A connecting rope 302 is located on the right side of the top of the body 1, which can be wound and tightened. The other end of the connecting rope 302 is fixedly connected to a moving block 303. A fan 306 is located on the front side of the moving block 303. An elastic rope 304 is fixedly connected to the left side of the moving block 303, which serves to reset it.

The drive assembly 305 includes a motor 3051. The motor 3051 is located on the top right side of the body 1. The output end of the motor 3051 is fixedly connected to the rotating shaft 3052. The kinetic energy of the motor 3051 drives the rotating shaft 3052 to rotate. A support plate 4 is provided on the outside of the body 1. The front side of the support plate 4 is fixedly connected to the rear side of the motor 3051. The support plate 4 is used to fix the motor 3051. A sliding groove 9 is provided on the outside of the body 1. The sliding groove 9 is opened on the top of the L-shaped plate 301. The moving block 303 can slide in the sliding groove 9. Specifically, the motor 3051 is started, driving the rotating shaft 3052 to rotate, which in turn winds the connecting rope 302 to tighten it, pulling the moving block 303 to move. The elastic rope 304 is stretched, and the fan 306 at the front end of the moving block 303 moves and starts to blow away debris. When the motor 3051 stops or reverses, the elastic rope 304 releases its stored elastic potential energy, causing the moving block 303 to reset, and the fan 306 resumes its cleaning work. By controlling the operating state of the motor 3051, the reciprocating movement and multi-angle blowing of the fan 306 are achieved, effectively preventing debris accumulation and thus not affecting subsequent processing.

[0029] Working principle: When fixing the stone, the stone is placed on the mounting block 205 at the top of the machine body 1. The spring 207 provides initial clamping force to the clamping block 208 through the fixing plate 206 to initially fix the stone. Rotating the knob 203 in the middle of the vertical plate 201 drives the threaded rod 202 to rotate, causing the U-shaped plate 204 connected by the rear thread to move towards the stone. The U-shaped plate 204 and the clamping block 208 work together to adjust the clamping position and force according to the shape of the stone, so as to achieve stable fixing of stones of different shapes and adapt to the processing needs of complex shapes of stones. The motor 3051 is started, which drives the rotating shaft 3052 to rotate. The connecting rope 302 is wound around and tightened, which pulls the moving block 303 to move. The elastic rope 304 is stretched, and the fan 306 on the front side of the moving block 303 moves and turns on, blowing away the debris. When the motor 3051 stops or reverses, the elastic rope 304 releases its elastic potential energy, pulling the moving block 303 to reset. The fan 306 cleans again. By controlling the operating state of the motor 3051, the reciprocating movement of the fan 306 and multi-angle blowing are realized, avoiding the accumulation of debris that will affect subsequent processing.
