Description

Technical Field

[0001] The utility model relates to a grinding device, and more particularly to a grinding device for artificial boards. Background Art

[0002] To ensure the flatness of the surface of artificial boards, both sides must be polished. Therefore, artificial board polishing equipment capable of double-sided polishing is widely used in board manufacturing plants, effectively meeting production needs. The main body 1 of existing artificial board polishing equipment is equipped with a lower polishing roller 2, an upper polishing roller 3, and guide pressure rollers 4 located on either side of the polishing rollers. During polishing, the upper polishing roller moves downward under the drive of a hydraulic device, polishing both sides of the artificial board together with the lower polishing roller. The guide pressure rollers on either side of the polishing rollers provide pressure and conveyance for the artificial board. As polishing progresses, the polishing rollers wear. Once the wear reaches a certain level, the polishing rollers or the polishing layer on the polishing rollers need to be replaced. Currently, the degree of wear on the polishing rollers is mainly determined manually by visual inspection, such as visually inspecting the wear on the polishing rollers or visually inspecting the polished surface of the artificial board after polishing. However, this inspection method requires considerable worker experience and often results in inaccurate judgments. Utility Model Content

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the embodiments, but this does not constitute any limitation to the present invention. Any limited modifications made by anyone within the scope of the claims of the present invention are still within the scope of the claims of the present invention.

[0020] See Figure 1-Figure 3The present invention provides a wood-based panel grinding device comprising a main body 1, which is provided with a lower grinding roller 2 and an upper grinding roller 3. A loading mechanism 5 is provided on one side of the main body 1. When the wood-based panel needs to be ground, the upper grinding roller 3 moves downward under the drive of a hydraulic device and grinds both sides of the wood-based panel with the lower grinding roller 2. Guide pressure rollers 4 on either side of the grinding rollers compress and transport the wood-based panel. The above is a brief introduction to the grinding function of the wood-based panel grinding device. Since it is prior art, it will not be further elaborated.

[0021] In order to detect the degree of wear of the grinding roller in the artificial board grinding equipment, the present invention makes the following improvements based on the traditional artificial board grinding equipment: a mounting cavity 6 is provided above the main body 1, and a transverse drive 7, such as an electric slide rail, is installed in the mounting cavity 6. An electric telescopic device 8, such as an electric push rod, is installed at the driving end of the transverse drive 7. A mounting box 9 is installed at the end of the electric telescopic device 8, and a motor 19 is installed in the mounting box 9. A connecting rod 10 is fixed to the driving end of the motor 19, and the connecting rod 10 passes through and extends to the outside of the mounting box 9. A detection end 15 is provided on the connecting rod 10. The thickness of the detection end 15 is consistent with the thickness of the artificial board. A pressure sensor 16 is embedded in the detection end 15, and the pressure sensor 16 is electrically connected to the controller. During testing, the detection end 15 is moved to the top of the lower grinding roller 2 and into contact with it by the driving action of the electric telescopic device 8 and the motor 19. Then, the upper grinding roller 3 is controlled to move down to the position when grinding the artificial board, so that the pressure sensor 16 can generate a pressure signal. After the controller reads the pressure signal, it compares the collected pressure with the set pressure range. If it does not exceed the pressure range, it means that the wear of the grinding roller is within the normal range; if it exceeds the pressure range, it means that the wear of the grinding roller is too great, causing the distance between the two grinding rollers to increase, resulting in less pressure applied to the pressure sensor 16. In this case, the grinding roller / the grinding layer on the grinding roller is replaced. When no testing is required, the connecting rod 10 is stored in the mounting cavity 6 and will not affect the grinding function of the equipment. The transverse drive 7 can drive the connecting rod 10 to move along the axial direction of the grinding roller to detect different positions of the grinding roller.

[0022] To improve the stability of the connecting rod 10 and ensure the horizontal position of the detection end 15, a positioning groove 17 is formed on the inner wall of the mounting box 9 of this embodiment. A positioning end 18 is provided at the end of the connecting rod 10 away from the detection end 15. The positioning end 18 is inserted into the positioning groove 17, and the height of the positioning groove 17 is consistent with the thickness of the positioning end 18. The positioning groove 17 positions the other end of the connecting rod 10, which can effectively improve the horizontal stability of the connecting rod 10.

[0023] Preferably, the mounting box 9 is cylindrical, with a notch on the side wall thereof having a length of 1 / 4 of its circumference, through which the connecting rod 10 is inserted. This arrangement is to ensure that the connecting rod 10 does not rotate excessively, so that after rotation, the connecting rod 10 can only be positioned perpendicular or parallel to the grinding roller, thereby avoiding interference between the connecting rod 10 and the guide pressure wheel 4.

[0024] Preferably, the connecting rod 10 is a square rod, which is convenient for installing the pressure sensor. The interior of the connecting rod 10 is provided with a honeycomb structure, which makes the connecting rod 10 lightweight.

[0025] The connecting rod 10 can be made of a metal rod or a carbon fiber rod. In this embodiment, a carbon fiber rod is preferably selected to further reduce the weight of the connecting rod 10.

[0026] The drive end of the transverse actuator 7 in this embodiment is equipped with a distance sensor 11, which is electrically connected to the controller and is used to detect the distance between it and the connecting rod 10. Because the height of the distance sensor 11 relative to the lower grinding roller 2 remains constant, when the connecting rod 10 is in contact with the lower grinding roller 2, the distance between it and the distance sensor 11 is fixed. Therefore, the installation of the distance sensor 11 can detect whether the connecting rod 10 is in place, ensuring smooth and accurate testing of grinding roller wear. Furthermore, the state of the electric expander 8 at its maximum extension can be set as the contact state of the connecting rod 10 and the lower grinding roller 2, thus eliminating the need to calculate and design the extension length of the electric expander 8.

[0027] In addition, the discharge end of the main body 1 of this embodiment is equipped with a laser beam 14, which is electrically connected to the controller and is used to count the number of boards being polished. When a wood-based panel passes through the laser beam 14, the laser is blocked, and the output state of the laser beam 14 changes, causing the controller to count +1, thereby counting the number of boards being polished. When the count reaches a set value, the feed is stopped, and the wear of the grinding roller is checked.

[0028] There are longitudinal actuators 12 below the main body 1 at both ends of the installation cavity 6, which can be electric slides. A closed door 13 is fixed to the driving ends of the two longitudinal actuators 12 to seal the installation cavity 6 and prevent dust from entering the installation cavity 6.

[0029] The working principle of the present invention is as follows: when the equipment is started, the longitudinal drive 12 is started to open the closed door 13, and then the electric telescopic device 8 is started to drive the installation box 9 to move downward.

[0030] When the electric expander 8 stops moving, the motor 19 starts to drive the connecting rod 10 to move above the lower grinding roller 2. The controller then reads the distance value from the distance sensor 11. If the distance value matches the preset value, it indicates that the connecting rod 10 is in contact with the grinding roller. The upper grinding roller 3 is then controlled to move down to the grinding position, and the controller reads the pressure signal from the pressure sensor 16. This pressure signal is compared with the preset range to determine whether the wear level of the grinding roller exceeds the wear level. If not, the motor 19 resets the connecting rod 10, and the transverse drive 7 drives the connecting rod 10 to another position. The wear level of the corresponding position on the grinding roller is then tested.

[0031] After the test is completed, the installation box 9, connecting rod 10 and closing door 13 are reset and stored in the installation cavity 6, and then the material can be loaded and polished. When the controller counts the laser beam 14 to the set value, the feeding is stopped and the wear of the grinding roller is tested again.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention. These modifications and improvements will not affect the effect of the implementation of the present invention and the practicality of the patent.
