[0047] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:

[0048] Embodiment 1

[0049] Depend on Figures 1 to 4 As shown, the present invention provides a plate grinding device, which includes a shell component, a fixing component and a grinding component.

[0050] The housing assembly includes a fixing seat 18. The fixing assembly includes a mounting post 16 rotatably disposed on the fixing seat 18, and a fixing member 11 disposed on the mounting post 16. The grinding assembly includes at least two grinding members 4 slidably disposed on the fixing seat 18, and grinding discs 10 respectively disposed on the grinding members 4.

[0051] The grinding component 4 can drive the grinding disc 10 to rotate to grind the plate fixed to the fixing component 11. The grinding component 4 can also slide to move away from the fixing component so that the fixing component can rotate and drive the plate to another grinding component 4 for secondary grinding.

[0052] Specifically, the plate is quickly fixed by the fixing component 11, and the plate is driven to switch between the two stations, so that the plate can be quickly subjected to a more refined secondary grinding. There is no need to move the plate on different machines or replace the grinding disc 10, which greatly improves production efficiency. In addition, the double stations can grind at the same time, which greatly improves production efficiency.

[0053] It is understandable that in this embodiment, there are two grinding parts 4 and they are symmetrically arranged. The grinding disc 10 includes a primary grinding disc and a secondary grinding disc respectively arranged on the two grinding parts 4. In other embodiments, multiple grinding discs can be arranged around the mounting column 16, and they only need to be directly opposite to the mounting column 16, and do not need to be symmetrically arranged. As long as it can grind the plate close to the fixed component and is away from the fixed component so that the fixed component can rotate, the present invention does not make specific restrictions on this, and only changes in quantity belong to the protection scope of the present invention.

[0054] In addition, if Figure 2 As shown, in this embodiment, the number of fixing components 11 is two. In other embodiments, the number of fixing components 11 can be multiple, and the circumference is evenly distributed on the mounting column 16, so that the fixing assembly can clamp and fix more plates at the same time. When there are only two grinding components 4, only two plates can be ground at a time. While grinding the plates, the fixing components 11 outside the grinding station can be clamped and removed. That is, the plates can be taken in and out while grinding, which further improves the production efficiency.

[0055] like Figure 3 and Figure 4 As shown, based on the above embodiment, in an optional embodiment of the present invention, the fixing component 11 includes a support plate 36 configured on the mounting column 16, a limit plate 24 configured on the support plate 36, a front support seat 21 and a second spring rod 23. A clamping groove for clamping a plate is formed between the limit plate 24 and the front support seat 21. The front support seat 21 is movably configured on the support plate 36, and the second spring rod 23 is used to drive the front support seat 21 to move closer to the limit plate 24.

[0056] Specifically, the spring rod refers to a spring sleeved on a guide rod. The guide rod of the first spring rod 27 is slidably arranged on the support plate 36, and one end is arranged on the front support seat 21. When the front support seat 21 approaches the support plate 36, the spring is compressed. The limit plate 24 is arranged above the front support seat 21, and when the spring drives the front support seat 21 away from the support plate 36, a clamping structure is formed between the limit plate 24. Through this structure, the plate can be clamped quickly, thereby saving the clamping time.

[0057] like Figure 3 and Figure 4 As shown, based on the above embodiment, in an optional embodiment of the present invention, the fixing component 11 further includes an inner slide bar 22 slidably disposed on the support plate 36, and a rear support seat 35 disposed at one end of the inner slide bar 22. The inner slide bar 22 slidably passes through the support plate 36. The front support seat 21 is disposed at the other end of the inner slide bar 22.

[0058] The front support seat 21 and the rear support plate 36 are linked together by the inner slide rod 22, and can be driven by the rear support plate 36 during clamping, thereby reducing the parts on the fixed component 11 facing the grinding component side, reducing the probability of collision during rotation, and preventing the dust generated during the grinding process from causing the parts of the fixed component to become stuck.

[0059] like Figure 3 and Figure 4As shown, on the basis of the above embodiment, in an optional embodiment of the present invention, the support plate 36 is provided with a slide groove located on the side of the front support seat 21. The fixing component 11 also includes a slide seat 26 and a first spring rod 27 configured in the slide groove. The limit plate 24 is configured on the slide seat 26. The first spring rod 27 is used to drive the slide seat 26 to approach the front support seat 21. The fixing component 11 also includes a wire pulley 28 configured on the side of the support plate 36 and a hanging ear 31 configured on the rear support seat 35, and a traction line 29 bypassing the wire pulley 28 and connected to the hanging ear 31 and the slide seat 26.

[0060] Specifically, the front support seat 21 and the rear support plate 36 are linked together through the inner slide bar 22, and the limit plate 24 and the rear support plate 36 are linked together through the slide seat 26, the first spring rod 27, the guide wheel 28, the hanging ear 31 and the traction line 29. When the fixed seat 18 is away from the support plate 36, not only the front support seat 21 can be driven away from the limit plate 24 through the inner slide bar 22, but also the slide seat 26 can be driven away from the front support seat 21 through the traction line 29. It is ensured that the plate can be clamped easily. And it will not be stuck because the clamping position is too small.

[0061] The guide rod of the second spring rod 23 is slidably arranged at the end of the slide groove, and the end is fixed on the slide seat 26. When the slide seat 26 is away from the front support seat 21, the spring can be compressed. The slide groove is provided to make the slide seat 26 slidable on the support plate 36, which belongs to the conventional technical means in the art, and its specific structure is not repeated.

[0062] In this embodiment, the support plate 36 is rectangular, and except for one side close to the feed port 3, the other three sides are provided with slide seats 26 for clamping the plate, and each side is provided with two slide grooves to ensure that the plate can be fixed on the fixing component 11 more stably.

[0063] like Figure 1 and Figure 2 As shown, based on the above embodiment, in an optional embodiment of the present invention, the housing assembly further includes a base 1 for supporting a fixing seat 18, and a top box 2 and a first motor 17 disposed on the base 1. The first motor 17 is used to drive the mounting column 16 to rotate. The top box 2 is used to cover the mounting column 16, the fixing component 11, and the grinding assembly. The top box 2 is provided with a feed port 3 facing the fixing component 11.

[0064] Specifically, the first motor 17 is used to drive the mounting column 16 to rotate, which can not only save manpower but also improve efficiency. The top box 2 is used to cover the mounting column 16, the fixing component 11, and the grinding assembly, which can effectively isolate the noise generated during the grinding process.

[0065] like Figure 1 and Figure 2As shown, based on the above embodiment, in an optional embodiment of the present invention, the housing assembly further includes a water tank 20 disposed on the base 1, a nozzle 25 disposed on the top box 2 or the slide 26, and a water pump for connecting the water tank 20 and the nozzle 25. The water tank 20 is connected to the liquid collecting tank below the fixed seat 18 through the conduit 19.

[0066] Specifically, a liquid collecting tank is provided on the base 1, and water is sprayed into the top box 2 through the nozzle 25, which can not only effectively reduce the dust generated during the grinding process, but also cool the grinding disc 10 and the plate to prevent stress from being generated during the grinding process. It has good practical significance. Preferably, the nozzle 25 sprays water directly at the grinding station.

[0067] like Figure 3 and Figure 4 As shown, based on the above embodiment, in an optional embodiment of the present invention, the fixing assembly further includes a movable seat 34 configured on the rear support seat 35, a pressure spring 14 configured on the movable seat 34, and a pressure sensor 33 configured between the pressure spring 14 and the movable seat 34. The fixing assembly further includes a screw rod 15 rotatably configured on the top box 2, a spring seat 12 configured on the screw rod 15, and a second motor 13 transmission-connected to the screw rod 15. The pressure spring 14 is configured on the spring seat 12.

[0068] Specifically, the second motor 13 can drive the screw 15 to rotate, so as to drive the rear support seat 35 away from the support plate 36 through the pressure spring 14. The clamping and loosening of the fixing component 11 are driven by the second motor 13, which greatly saves manpower. A pressure sensor 33 is provided, and the specific height of the spring seat 12 can be controlled by the second motor 13, so as to adjust the supporting force applied to the front support seat 21. When grinding, the grinding disc 10 abuts against the front of the plate, and the front support seat 21 abuts against the back of the grinding disc 10. The pressure between the plate and the grinding disc 10 can be adjusted by the second motor 13.

[0069] like Figure 4 As shown, based on the above embodiment, in an optional embodiment of the present invention, the front support seat 21 is provided with a dust removal hole. The rear support seat 35 is provided with a cavity. The shell is provided with a dust discharge port. The fixed component 11 also includes an air pump 32 configured in the cavity, and a dust removal pipe 30 configured in the air pump 32. The input end of the air pump 32 is connected to the dust removal hole. The dust removal pipe 30 extends outward from the side of the rear support seat 35 and faces the dust discharge port.

[0070] Specifically, the vacuum pump 32 can be used to suck the dust generated by grinding to a predetermined position for collection, thereby preventing the dust from flying around during the grinding process, which has a very good practical significance for maintaining a clean and tidy grinding environment.

[0071] like Figure 2As shown, based on the above embodiment, in an optional embodiment of the present invention, the grinding assembly includes a support rod 5 and a driving motor 6 slidably configured on a fixed seat 18, a sleeve 7 configured on the support rod 5, and a transmission shaft 8 rotatably configured on the sleeve 7. The grinding disc 10 is configured on the transmission shaft 8. The driving motor 6 is used to drive the transmission shaft 8 to rotate, and drive the grinding disc 10 to rotate.

[0072] Specifically, the grinding disc 10 and the drive motor 6 are connected by the support rod 5, the shaft sleeve 7, and the transmission shaft 8, so that the angle of the grinding disc 10 can be fixed to be tilted. Similarly, the fixing component 11 and the grinding disc 10 are set to be parallel and tilted. It is more convenient to take and put the plate. In addition, the motor can also be wrapped by the motor shell to prevent the dust generated by grinding from directly contacting the motor, thereby ensuring the life of the drive motor 6.

[0073] like Figure 2 As shown, based on the above embodiment, in an optional embodiment of the present invention, the grinding component 4 further includes a slide plate, a motor housing and a grinding disc seat 9. The grinding disc seat 9 is arranged on the transmission shaft 8 to fix the grinding disc 10. The slide plate is slidably arranged on the fixing seat 18. The driving motor 6 is fixed on the slide plate through the motor housing. The housing assembly also includes an electric push rod arranged on the fixing seat 18. The electric push rod is used to drive the slide plate to slide.

[0074] Specifically, the support rod 5 can be directly slidably configured on the fixed seat 18, or can be fixed on a slide plate and slide relative to the fixed seat 18 through the slide plate. Through the slide plate, the grinding component 4 can slide on the fixed seat 18, thereby adjusting the distance between the grinding disc 10 and the plate. When the fixed component is to be rotated, the grinding disc 10 is kept away from the plate to avoid collision during the rotation process.

[0075] In this embodiment, the grinding disc 10 is fixed to the transmission shaft 8 via the grinding disc seat 9, which greatly facilitates the replacement of the grinding disc 10. In other embodiments, the grinding disc 10 can also be directly fixed to the transmission shaft 8, and the present invention does not make specific limitations on this.

[0076] Embodiment 2

[0077] The present invention provides a control method for a plate grinding device, which is used to control the plate grinding device as described in any paragraph of the first aspect to grind the plate, and the method comprises the following steps:

[0078] S1. The fixing assembly fixes the plate and places the plate at the first grinding station.

[0079] S2. The first grinding component drives the first grinding disc to rotate, and performs the first grinding on the plate.

[0080] S3. Move the grinding part away from the fixed component.

[0081] S4. Rotate the mounting column to move the plate to the second grinding station.

[0082] S5. Move the grinding part to bring it closer to the fixed component.

[0083] S6. The second grinding component drives the second grinding disc to rotate, and performs a second grinding on the plate.

[0084] S7. Release the plate.

[0085] Specifically, when fixing the plate, the second motor drives the spring seat away from the support plate through the screw rod. The spring seat drives the rear support plate, the inner slide rod, and the front support seat to move backward through the pressure spring, and the rear support plate drives the slide seat to move outward through the traction line, thereby forming a space for accommodating the plate.

[0086] After the plate is placed in the space, the second motor rotates in the reverse direction to make the fixing component clamp the plate. The first spring rod and the second spring rod can offset the vibration of the plate during the grinding process, thereby ensuring the quality of the grinding, and the plate will not break during the grinding process.

[0087] The first grinding component drives the primary grinding disc to rotate to perform the first grinding on the plate. The primary grinding disc is for rough grinding.

[0088] After the first grinding is completed, the electric push rod drives the slide away from the fixed component, and then the first motor drives the fixed component to rotate to move the plate to the second grinding station. The second grinding station is the position of the second grinding disc.

[0089] After the plate is moved into position, the electric push rod drives the second grinding component to approach the fixed component, so that the secondary grinding disc abuts against the plate.

[0090] Then, the second grinding component drives the secondary grinding disc to rotate and grind the plate for the second time. The secondary grinding disc is for fine grinding.

[0091] After the grinding is completed, the plate can be taken out. Or the plate can be rotated to another position and then taken out.

[0092] The plate can be quickly fixed by the fixing parts, and the plate can be switched between two stations, so that the plate can be quickly and finely ground again. There is no need to move the plate on different machines or change the grinding disc, which greatly improves production efficiency. In addition, the double stations can grind at the same time, which greatly improves production efficiency.

[0093] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
