Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, and in particular to a transport and guiding device for stone cutting. Background Technology

[0002] In the field of stone cutting and processing, transport guidance equipment is crucial for ensuring the accurate and stable transport of stone. Existing stone transport guidance devices usually have guide wheels on both sides above the conveyor belt to guide the direction of the stone's movement, ensuring that it accurately enters the cutting area, thereby improving cutting accuracy and production efficiency.

[0003] However, a key problem with current guide wheels is the difficulty in monitoring and judging their wear in real time and accurately. Under the long-term contact with stone and the pressure and friction of the stone, the surface of the guide wheel inevitably wears down. Once the guide wheel wears to a certain extent, the contact state between it and the stone changes, leading to a decrease in guiding accuracy. This can cause the stone to deviate, shake, or even jam during transport, severely affecting the quality and efficiency of stone cutting, increasing the scrap rate, and potentially negatively impacting subsequent processing steps. It can even damage other parts of the equipment, increasing maintenance costs and downtime. Currently, guide wheel wear detection mostly relies on manual inspection by workers, which suffers from untimely and inaccurate detection. Furthermore, the environment in stone processing plants is usually harsh and dusty, further increasing the difficulty and inaccuracy of manual inspection. Utility Model Content

[0004] Therefore, this utility model proposes a transport and guiding device for stone cutting, which can detect the wear condition of the guide wheels so as to replace the guide wheels in a timely manner, thereby ensuring the stability of stone transport and cutting.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A transport and guiding device for stone cutting includes a frame, a mounting frame, a transport roller, support columns, a load-bearing rod, guide wheels, and a wear detection mechanism.

The electric push rod is mounted on the bottom surface of the horizontal plate, and its output shaft is connected to the top surface of the pulling block. The tension sensor is mounted on the bottom surface of the pulling block. The side wall of the contact block is slidably connected to the side wall of the vertical plate and is located on one side of the guide wheel. The tension spring connects the bottom surface of the tension sensor and the top surface of the contact block. The main control unit is mounted on the side wall of the vertical plate and is electrically connected to the electric slide table, the rotating mechanism, the electric push rod, and the tension sensor respectively.

[0007] Preferably, it also includes an extension rod, one end of which is connected to the top of the support column and the other end of which is connected to the side wall of the bearing rod.

[0008] Preferably, the wear detection mechanism further includes an indicator light, which is disposed on the bottom surface of the support plate and corresponds to the position of the guide wheel, and the main control unit is electrically connected to the indicator light.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention provides a transport and guiding device for stone cutting. The mounting frame is installed on the machine frame, and the transport rollers mounted on it can transport the stone. Guide wheels on the side wall of the bearing rod guide the stone, ensuring stable transport. When not in operation, the rotating structure drives the rotating rod to rotate, which in turn rotates the horizontal and vertical plates. The final contact block rotates to the side of the guide wheel and contacts it. Then, the electric push rod drives the pulling block upwards, pulling the contact block via a tension spring. When the contact block moves, the tension sensor collects data about the tension spring as the contact friction force between the contact block and the guide wheel, thus assessing the wear condition of the guide wheel. When the guide wheel is worn, it can be replaced promptly, ensuring stable stone transport. Attached Figure Description

[0021] To better understand the technical content of this utility model, a specific embodiment is provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0022] See Figures 1 to 4 This utility model provides a transport and guiding device for stone cutting, including a frame body 1, a mounting frame 2, a transport roller 3, a support column 4, a bearing rod 5, a guide wheel 6, and a wear detection mechanism. The mounting frame 2 is mounted on the frame body 1, the transport roller 3 is mounted on the mounting frame 2, the support column 4 is symmetrically arranged on the top surface of the frame body 1 and located on both sides of the transport roller 3, the side wall of the bearing rod 5 is connected to the top of the support column 4, and the guide wheel 6 is located on the opposite side wall of the bearing rod 5. The wear detection mechanism includes an electric slide table 7, a rotating rod 8, a rotating mechanism, a horizontal plate 9, a vertical plate 10, an electric push rod 11, a pulling block 12, a tension sensor 13, a tension spring 14, a contact block 15, and a main control unit 16. The electric slide 7 is mounted on the top surface of the support rod 5. The rotating mechanism is mounted on the mover of the electric slide 7 and is used to drive the rotating rod 8 to rotate. One end of the horizontal plate 9 is connected to the circumferential surface of the rotating rod 8, and the other end is connected to the top of the vertical plate 10. The electric push rod 11 is mounted on the bottom surface of the horizontal plate 9, and its output shaft is connected to the top surface of the pull block 12. The tension sensor 13 is mounted on the bottom surface of the pull block 12. The side wall of the contact block 15 is slidably connected to the side wall of the vertical plate 10 and is located on one side of the guide wheel 6. The tension spring 14 connects the bottom surface of the tension sensor 13 and the top surface of the contact block 15. The main control unit 16 is mounted on the side wall of the vertical plate 10 and is electrically connected to the electric slide 7, the rotating mechanism, the electric push rod 11, and the tension sensor 13 respectively.

[0023] The frame 1 is installed in the stone processing plant. A mounting frame 2 is set on top of the frame 1 to install multiple transport rollers 3. The stone can be moved by the transport rollers 3. On both sides above the transport rollers 3 are bearing rods 5, which are supported by support columns 4. Guide wheels 6 are set on the opposite side walls of the bearing rods 5. When the stone is transported on the transport rollers, its side walls can move stably under the guidance of the guide wheels 6 to avoid deviation during movement. After the stone cutting equipment is placed above the frame 1, the stone can be cut, ensuring the stability of the cutting.

[0024] An electric slide 7 is installed at the top of the support rod 5, which can drive the rotating mechanism and the rotating rod 8 to move. The rotating rod 8 can drive the horizontal plate 9 and the vertical plate 10 to rotate under the drive of the rotating mechanism. The contact block 15 on the side wall of the vertical plate 10 can rotate to the side of the guide wheel 6 and contact the guide wheel 6. At this time, the main control unit 16 can drive the electric push rod 11 to drive the pulling block 12 to move slowly upward. During the upward movement of the pulling block 12, the contact block 15 will be pulled by the tension spring 14. In the early stage, due to the friction between the contact block 15 and the guide wheel 6... The friction force causes the tension spring 14 to be stretched while the contact block 15 remains stationary. When the tension force of the tension spring 14 on the contact block 15 is greater than the friction force, the contact block 15 will be pulled. The tension data collected by the tension sensor 13 when the contact block 15 is pulled is regarded as the friction force between the guide wheel 6 and the contact block 15. By comparing the friction force with the preset standard friction force of the guide wheel 6, it can be determined whether the guide wheel 6 is worn. If wear exists, it can prompt the staff to replace it in time to ensure that the stone can be stably transported on the transport roller 3.

[0025] When friction detection is not required, the rotating rod 8 can drive the horizontal plate 9 and the vertical plate 10 to rotate to the outer side above the transport roller 3 to avoid affecting the normal transport of the stone. The main control unit 16 of this utility model is implemented by a single-chip microcomputer of the STM32 series, while the tension sensor 13 is of the STW28 model.

[0026] Preferably, it also includes an extension rod 17, one end of which is connected to the top of the support column 4, and the other end is connected to the side wall of the bearing rod 5.

[0027] The extension rod 17 is used to install the support rod 5, and at the same time, the support rod 5 can extend above the edge of the transport roller 3 to ensure that the guide wheel 6 can contact the side wall of the stone.

[0028] Preferably, the wear detection mechanism further includes an indicator light 18, which is disposed on the bottom surface of the support plate and corresponds to the position of the guide wheel 6. The main control unit 16 is electrically connected to the indicator light 18.

[0029] Each indicator light 18 corresponds to a guide wheel 6. When the guide wheel 6 is worn, the main control unit 16 can drive the corresponding indicator light 18 to light up, so as to remind the staff that there is a worn guide wheel 6.

[0030] Preferably, the rotating mechanism includes a U-shaped frame 19 and an electric turntable 20. The U-shaped frame 19 is disposed on the top surface of the moving part of the electric slide table 7, and the electric turntable 20 is disposed on the inner side wall of the U-shaped frame 19. Its rotating surface is connected to the end of the rotating rod 8, and the main control unit 16 is electrically connected to the electric turntable 20.

[0031] The electric slide table 7 can move the U-shaped frame 19, so that the contact block 15 can move to the outside of different guide wheels 6, while the electric turntable 20 can drive the rotating rod 8 to rotate, so as to realize the rotation of the horizontal plate 9 and the vertical plate 10, thereby switching between the two working processes of wear detection or stone conveying.

[0032] Preferably, the sidewall of the contact block 15 is provided with a T-shaped block 21, the sidewall of the vertical plate 10 is provided with a T-shaped groove 22, and the T-shaped block 21 is located in the T-shaped groove 22.

[0033] When the tension sensor 13 pulls the contact block 15 upward, the T-shaped block 21 can move along the T-shaped groove 22, which can prevent the contact block 15 from falling off the vertical plate 10, and at the same time limit the movement of the contact block 15.

[0034] Preferably, the wear detection mechanism further includes a fan 23, which is disposed on the side wall of the pull block 12 and located above the guide wheel 6, and the main control unit 16 is electrically connected to the fan 23.

[0035] The fan 23 can blow away dust or particles on the guide wheel 6 before wear detection, so as to avoid affecting the wear detection results of the guide wheel 6.

[0036] Preferably, the wear detection mechanism further includes an arc-shaped plate 24, which is disposed on the side wall of the contact block 15 and is used to abut against the outer wall of the guide wheel 6.

[0037] The arc-shaped plate 24 is designed to fit against the circumferential surface of the guide wheel 6 in order to accurately detect the wear condition of the guide wheel 6.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
