Description

Technical Field

[0001] The utility model relates to the field of sheet metal forming processing, and in particular to a building material surface grinding device. Background Art

[0002] Polishing refers to grinding or rubbing the surface of an object to make it smooth and delicate. Its function is to remove burrs, floating rust, oil stains, dust on the surface of the substrate, remove coarse particles and impurities on the surface of the coating, and obtain a smooth surface. The smooth coating surface should be polished to a certain degree of roughness to enhance the adhesion of the coating. The polishing area and depth depend on the degree of damage. According to regulations, it should be polished until there are no signs of damage or aging cracks.

[0003] As society develops faster and faster, the use and requirements of building materials are getting higher and higher. Polishing, cutting and grinding are commonly used processes in building materials processing. Especially in the process of grinding building materials, the existing grinding devices have complex structures, low grinding efficiency, low degree of automation, cannot effectively improve the grinding efficiency, and have high labor intensity.

[0004] However, the patents in the prior art have the following disadvantages:

[0005] (1) The prior art patent places the sheet metal into the placement slot during use, and then the pushing block pushes the sheet metal through the grinding shaft for grinding. However, since the width of the sheet metal may change, the sheet metal may not be placed in the placement slot, and the grinding work cannot be completed;

[0006] (2) The prior art patent uses a grinding shaft to grind the sheet metal during use, which can only remove the surface of the upper surface of the sheet metal, making it impossible to remove the surface of both sides of the sheet metal;

[0007] (3) In the prior art, all the waste generated when removing the surface is accumulated on the processing table. The long-term accumulation of waste will affect the environment of the processing table and also affect the service life of the grinding device. Utility Model Content

[0031] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0032] like Figures 1 to 7As shown, a building material surface grinding device includes a box body 1, a fixed bracket 2, a motor 3, a motor 4, a rocker 5, a moving structure 6, a telescopic structure 7, a conveying structure 8, a grinding structure 9, a first friction plate 10, a second friction plate 11, a first limiting groove 12, a second limiting groove 13, a third limiting groove 14, a collection box 15, a handle 16, a positioning hole 17, a positioning column 18, a threaded screw 601, a threaded sleeve 602, a limiting block 603, a threaded screw The second 701, two threaded sleeves 702, the second limit block 703, the threaded screw 801, the threaded sleeve 802, the limit block 803, the push plate 804, the electric telescopic rod 901, the motor 902, the grinding ball 903, the fan 904; the fixed brackets 2 are fixedly arranged on both sides of the middle of the box body 1, the mobile structure 6 is rotatably connected to the top of the fixed bracket 2, and the grinding structure 9 is fixedly connected to the bottom of the mobile structure 6, so that the mobile structure 6 drives the grinding structure 9 is moved laterally to remove the surface on the upper surface of the sheet metal. The motor 2 4 is fixedly connected to one side of the fixed bracket 2 and its drive shaft passes through the fixed bracket 2. The rocker 5 is located on one side of the box body 1 and passes through the box body 1. The telescopic structure 7 is rotatably connected to the bottom of the cavity of the box body 1 through a bearing and one end of it is plugged into the rocker 5. The rocker 5 is rotated to control the telescopic structure 7. The first friction plate 10 and the second friction plate 11 are both located inside the box body 1 and fixedly connected to the telescopic structure 7. Both ends of the first friction plate 10 and the second friction plate 11 pass through the box body 1. The motor 1 3 is fixedly connected to one side of the fixed bracket 2 and its drive shaft passes through the fixed bracket 2. The conveying structure 8 is rotatably connected to the middle part of the box body 1 through a bearing and one end of it is sleeved on the drive shaft of the motor 1 3. The motor 1 3 drives the conveying structure 8 to start, and the sheet metal is transported from one end of the box body 1 to the other end, and at the same time, both sides of the sheet metal contact the first friction plate 10 and the second friction plate 11 to remove the surface on both sides of the sheet metal.

[0033] like Figure 3 and Figure 4 As shown, the movable structure 6 includes a threaded screw 601, a threaded sleeve 602 and a limit block 603. The threaded screw 601 is rotatably connected to the top of the fixed bracket 2 through a bearing. One end of the threaded screw 601 is sleeved on the driving shaft of the motor 4. The rotation of the driving shaft of the motor 4 drives the threaded screw 601 to rotate. The threaded sleeve 602 is sleeved on the threaded screw 601 and cooperates with the thread on the threaded screw 601. The rotation of the threaded screw 601 drives the threaded sleeve 602 to rotate. The two limit blocks 603 are fixedly connected to both sides of the threaded sleeve 602 and both pass through the third limit groove 14. However, since the limit block 603 cooperates with the third limit groove 14, the threaded sleeve 602 can only move laterally.

[0034] The polishing structure 9 includes an electric telescopic rod 901, a motor three 902, a polishing ball 903 and a fan 904. The electric telescopic rod 901 is fixedly connected to the bottom end of the threaded sleeve one 602 and passes through the third limiting groove 14. The electric telescopic column moves laterally with the threaded sleeve one 602. The motor three 902 is fixedly connected to the bottom end of the electric telescopic rod 901. When the sheet metal moves to a certain position, the electric telescopic rod 901 will be extended to make the polishing ball 903 contact the upper surface of the sheet metal. The fan 904 is fixedly connected to the driving shaft of the motor three 902. When the polishing ball 903 is polishing, the fan 904 will blow the removed surface into the collection box 15 to keep the polishing device clean. The polishing ball 903 is fixedly connected to the bottom end of the motor three 902.

[0035] like Figure 5 As shown, the conveying structure 8 includes a threaded screw 3 801, a threaded sleeve 3 802, a limit block 3 803 and a push plate 804. The threaded screw 3 801 is rotatably connected to the inside of the box body 1 through a bearing and one end of the threaded screw 3 801 is sleeved on the driving shaft of the motor 1 3. The rotation of the driving shaft of the motor 1 3 drives the threaded screw 3 801 to rotate. The threaded sleeve 3 802 is sleeved on the threaded screw 3 801 and cooperates with the thread on the threaded screw 3 801. The rotation of the threaded screw 3 801 drives the threaded sleeve 3 802 to rotate. The two limit blocks 3 803 are fixedly connected to both sides of the threaded sleeve 3 802 and both pass through the second limit groove 13. The limit blocks 3 803 cooperate with the second limit groove 13 to enable the threaded sleeve 3 802 to move longitudinally. The push plate 804 is fixedly connected to one side of the threaded sleeve 3 802 and is slightly higher than the upper surface of the threaded sleeve 3 802, so that the sheet metal can move on the upper surface of the threaded sleeve 3 802.

[0036] like Figure 6 and Figure 7 As shown, the telescopic structure 7 includes a threaded screw rod 2 701, two threaded sleeves 2 702 and a limit block 2 703. The threaded screw rod 2 701 is rotatably connected to the bottom of the cavity of the box body 1 through a bearing and one end of the threaded screw rod 2 701 is sleeved on the rocking plate 5. The rocking plate 5 is rotated to drive the threaded screw rod 2 701 to rotate. The two threaded sleeves 2 702 are sleeved on the threaded screw rod 2 701 and cooperate with the threads on the threaded screw rod 2 701. The rotation of the threaded screw rod 2 701 drives the two threaded sleeves 2 702 to rotate. The tops of the two threaded sleeves 2 702 are respectively fixedly connected to the first friction plate 10 and the second friction plate 11. The four limit blocks 2 703 are respectively fixedly connected to the two ends of the two threaded sleeves 2 702 and all pass through the first limit groove 12. Due to the cooperation between the limit block 3 803 and the first limit groove 12, the two threaded sleeves 2 702 move toward or away from each other, thereby adjusting the distance between the first friction plate 10 and the second friction plate 11.

[0037] A collection box 15 is slidably connected to the bottom of the box body 1, and the collection box 15 passes through the box body 1. A handle 16 is provided on one side of the collection box 15. After the grinding device has been used for a period of time, the collection box 15 can be pulled out of the box body 1 and cleaned to keep the grinding device tidy. A plurality of positioning holes 17 are provided on the front surface of the box body 1, and positioning columns 18 are slidably connected in the positioning holes 17. The positioning columns 18 pass through the box body 1. When the distance between the first friction plate 10 and the second friction plate 11 is adjusted, the positioning columns 18 are inserted into the positioning holes 17 to fix the first friction plate 10 and the second friction plate 11.

[0038] In specific use, first rotate the shaking plate 5 to adjust the distance between the first friction plate 10 and the second friction plate 11, insert the positioning column 18 into the positioning hole 17, so that the first friction plate 10 and the second friction plate 11 are fixed, and then the sheet metal is placed in the conveying structure 8 and the motor 24 is started. The motor 24 drives the shaft to rotate to drive the threaded screw 3 801 to rotate, and the second drives the threaded sleeve 3 802 to rotate. However, due to the cooperation between the limit block 3 803 and the second limit groove 13, the threaded sleeve 3 802 can only drive the push plate 804 to move, so that the two sides of the sheet metal rub against the first friction plate 10 and the second friction plate 11, thereby removing the surface of the two sides of the sheet metal, and then start the motor 13, and the motor 14. The driving shaft drives the threaded screw 1 601 to rotate, thereby rotating the threaded sleeve 1 602. However, due to the cooperation between the limiting block 1 603 and the third limiting groove 14, the threaded sleeve 1 602 drives the grinding structure 9 to move laterally. Then, the electric telescopic column is driven to make the grinding ball 903 contact the upper surface of the sheet metal. The motor 3 902 is started. The driving shaft of the motor 3 902 drives the fan 904 and the grinding ball 903 to rotate together. The grinding ball 903 removes the surface of the sheet metal. At the same time, the fan 904 blows the removed surface waste into the collection box 15 at the bottom of the box body 1. The collection box 15 is regularly taken out of the box body 1 and cleaned, which can extend the service life of the grinding device.

[0039] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
