Description

Technical Field

[0001] This invention relates to the field of abrasive belt technology, and more specifically, to an abrasive belt thickness measuring mechanism. Background Technology

[0002] A grinding belt is a tool used for grinding, polishing, or finishing the surface of a workpiece; it is usually a strip of abrasive material.

[0003] The current method of driving the grinding belt is to drive the driving wheel through the grinding motor, and the grinding belt is wound around the driven wheel of the driving wheel. When the driving wheel rotates, it drives the grinding belt to rotate, thereby achieving the grinding and cleaning function.

[0004] Currently, to ensure the grinding belt remains relatively flat during the grinding process, paper-based grinding belts are typically used as the base material. Paper-based grinding belts are suitable for light grinding and polishing of flat surfaces, providing sufficient support to ensure the grinding belt remains relatively flat. However, during the grinding process, the abrasive grains on the grinding belt surface wear or fall off, becoming blunt. Consequently, after prolonged use, the grinding belt thickness decreases, affecting product quality during grinding. Therefore, to ensure grinding quality, the grinding belt needs to be replaced. Currently, the degree of wear and falloff of the abrasive grains on the grinding belt is manually observed to determine whether replacement is necessary, but it is difficult to accurately assess the degree of wear and falloff. Summary of the Invention

[0031] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0032] Refer to the instruction manual appendix Figures 1-11 A grinding belt thickness measuring mechanism includes: a grinding mechanism 1 and a thickness measuring component 3. A grinding belt 11 is disposed on the grinding mechanism 1 and the grinding belt 11 is driven on the grinding mechanism 1. The thickness measuring component 3 includes a fixed plate 31 and a power component 34. Both the fixed plate 31 and the power component 34 are fixedly disposed on the grinding mechanism 1. A thickness measuring base plate 33 is disposed below the fixed plate 31. The output end of the power component 34 is fixedly connected to the thickness measuring base plate 33. The power component 34 is used to drive the thickness measuring base plate 33 to move vertically. A displacement sensor 32 is fixedly disposed on one side of the fixed plate 31. The bottom of the detection end of the displacement sensor 32 is flush with the bottom of the fixed plate 31. The grinding belt 11 passes between the fixed plate 31 and the thickness measuring base plate 33. During measurement, the power component 34 drives the thickness measuring base plate 33 to move upward, so that the thickness measuring base plate 33 and the fixed plate 31 clamp the grinding belt 11. The displacement sensor 32 is used to measure the distance between the displacement sensor 32 and the thickness measuring base plate 33.

[0033] It should be noted that the power component 34 is a cylinder.

[0034] In this embodiment, the specific implementation scenario is as follows: During testing, the cylinder drives the thickness measuring base plate 33 to move upward, so that the thickness measuring base plate 33 contacts the bottom of the grinding belt 11, and drives the grinding belt 11 to move upward, so that the top of the grinding belt 11 contacts the bottom surface of the fixing plate 31, thereby pressing the grinding belt 11 tightly with the thickness measuring base plate 33 and the fixing plate 31. At this time, the displacement sensor 32 measures the distance between the displacement sensor 32 and the thickness measuring base plate 33. This distance is the thickness of the grinding belt 11. If the thickness of the grinding belt 11 is less than the set value, the grinding belt 11 needs to be replaced in time to avoid affecting the grinding quality of the product.

[0035] Furthermore, the thickness measuring component 3 also includes a control unit 35 and an alarm unit 36, with the displacement sensor 32 connected to the control unit 35 and the control unit 35 connected to the alarm unit 36.

[0036] It should be noted that the control unit 35 is a PLC controller and the alarm unit 36 ​​is a buzzer. The measured thickness of the grinding belt 11 is transmitted to the PLC controller. If the thickness of the grinding belt 11 is not sufficient to meet the set value, the PLC controller will transmit a signal to the buzzer to sound an alarm and promptly remind the staff to replace the grinding belt 11.

[0037] However, in the above technical solution, in order to leave transmission space for the grinding belt 11, the grinding belt 11 is set between the thickness measuring base plate 33 and the fixing plate 31, and there will be a certain distance between the grinding belt 11, the thickness measuring base plate 33 and the fixing plate 31. Therefore, when the thickness measuring base plate 33 is driven to move upward and the grinding belt 11 is clamped by the fixed plate 31, the thickness measuring base plate 33 will apply an upward force to the grinding belt 11. This will cause the base material of the grinding belt 11 to be squeezed and deformed when the grinding belt 11 is clamped, which will cause the measurement data to be too small when measuring the thickness of the grinding belt 11. Furthermore, after long-term use, the grinding belt 11 will become thinner and harder due to wear. Therefore, when measuring the thickness of the grinding belt 11, the deformation of the grinding belt 11 cannot be predicted, resulting in the inability to measure the accurate thickness of the grinding belt 11. Therefore, this embodiment provides a clamping and lifting component to solve the above problems.

[0038] Furthermore, the thickness measuring mechanism also includes a clamping and lifting assembly for clamping the grinding belt 11 and lifting the grinding belt 11 to a position that contacts the bottom surface of the fixed plate 31.

[0039] It should be noted that pressure sensors are provided on both the fixed plate 31 and the thickness measuring base plate 33. The pressure sensor on the fixed plate 31 is used to stop the grinding belt 11 from moving when the pressure sensor detects that the grinding belt 11 just comes into contact with the bottom surface of the fixed plate 31 (just generating pressure) during the upward movement of the clamping and lifting assembly. The pressure sensor on the thickness measuring base plate 33 is used to stop the thickness measuring base plate 33 from moving when the pressure sensor detects that the thickness measuring base plate 33 just comes into contact with the bottom surface of the grinding belt 11 (just generating pressure) during the upward movement of the thickness measuring base plate 33. This prevents the grinding belt 11 from being deformed by pressure during the thickness measurement of the grinding belt 11, which could affect the measurement data.

[0040] like Figure 2 , Figure 3 and Figure 4As shown, this embodiment provides a specific structure of a clamping and lifting assembly, namely, a clamping and lifting component 4. The clamping and lifting assembly is the clamping and lifting component 4, which includes two clamping plates 41 that can move closer or further apart simultaneously. The two clamping plates 41 are located at the top and bottom of the grinding belt 11, respectively. The clamping and lifting component 4 also includes a fixed base 42. Both clamping plates 41 are slidably mounted on the fixed base 42. A power component 43 is fixedly mounted on the fixed base 42, and the output end of the power component 43 is fixedly connected to... A drive gear 44 is connected to the fixed base 42, and a driven gear 45 and two driven gears 46 are rotatably arranged inside the fixed base 42. The drive gear 44 meshes with the driven gear 45 and one of the driven gears 46. The driven gear 45 also meshes with the other driven gear 46. A rack 47 is fixedly arranged on each of the two clamping plates 41. The two driven gears 46 mesh with the corresponding racks 47. A power component 48 is fixedly arranged on the fixed base 42. The power component 48 is used to drive the fixed base 42 to move vertically.

[0041] It should be noted that there are two clamping and lifting components 4. The two clamping and lifting components 4 are located on both sides of the thickness measuring component 3. The power component 43 is a motor and the power component 48 is a cylinder. During measurement, the motor drives the drive gear 44 to rotate, and under the action of the driven gear 45, it drives the two driven gears 46 to rotate simultaneously. The two driven gears 46 rotate in opposite directions, so that under the action of the two racks 47, the two clamping plates 41 can move closer together to clamp the grinding belt 11. Then the cylinder drives the clamped grinding belt 11 to move upward, so that the top of the grinding belt 11 can contact the bottom surface of the fixed plate 31.

[0042] like Figure 5 and Figure 6 As shown, this embodiment provides a specific structure of a clamping and lifting assembly, namely, a clamping and lifting component 2 5. The clamping and lifting assembly is the clamping and lifting component 2 5, which includes two clamping plates 2 51 that can move closer or further apart synchronously. The two clamping plates 2 51 are located at the top and bottom of the grinding belt 11, respectively. The clamping and lifting component 2 5 also includes a fixed base 2 52. A power component 6 53 is fixedly installed on the fixed base 2 52. A connecting rod 54 is fixedly connected to the output end of the power component 6 53. Two hinge rods 55 are hinged to the connecting rod 54. A slider 56 is hinged to each of the two hinge rods 55. The two sliders 56 are slidably connected to the fixed base 2 52. The two clamping plates 2 51 are fixedly installed on the corresponding sliders 56. A power component 7 57 is fixedly installed on the fixed base 2 52. The power component 7 57 is used to drive the fixed base 2 52 to move vertically.

[0043] It should be noted that there are two clamping and lifting components 2 5, which are located on both sides of the thickness measuring component 3. The power component 6 53 is a motor, and the power component 7 57 is a cylinder. The motor drives the connecting rod 54 to rotate, which in turn drives the two hinge rods 55 to rotate. This causes the two hinge rods 55 to move the two clamping plates 2 51 closer together and clamp the grinding belt 11 through the two sliders 56. Then, the cylinder drives the clamped grinding belt 11 to move upward, so that the top of the grinding belt 11 can contact the bottom surface of the fixed plate 31.

[0044] like Figure 7 , Figure 8 and Figure 9 As shown, this embodiment provides a specific structure of a clamping and lifting assembly, namely, a clamping and lifting component 36. The clamping and lifting assembly is the clamping and lifting component 36, which includes two clamping plates 361 that can move closer or further apart synchronously. The two clamping plates 361 are located at the top and bottom of the grinding belt 11, respectively. The clamping and lifting component 36 also includes a fixed seat 362. A power component 8 63 is fixedly installed on the fixed seat 362. A worm gear 64 is fixedly connected to the output end of the power component 8 63. Two connecting rods 1 65 and two connecting rods 2 66 are rotatably installed inside the fixed seat 362. A worm wheel 67 is fixedly installed inside each of the two connecting rods 1 65. The worm gear 64 meshes with the two worm wheels 67. The ends of the connecting rods 1 65 and connecting rods 2 66 located on the same side are hinged to connecting blocks 68. The two clamping plates 361 are fixedly installed on the corresponding connecting blocks 68. A power component 9 69 is fixedly installed on the fixed seat 362. The power component 9 69 is used to drive the fixed seat 362 to move vertically.

[0045] It should be noted that there are two clamping and lifting components 36, which are located on both sides of the thickness measuring component 3. The power component 8 63 is a motor, and the power component 9 69 is a cylinder. The connecting rod 1 65, connecting rod 2 66, connecting block 68 and fixing seat 3 62 on the same side form a parallelogram structure. The motor drives the worm gear 64 to rotate, so that the two worm wheels 67 can drive the corresponding connecting rod 1 65 to rotate. Thus, under the combined action of the two connecting rods 2 66 and the two connecting blocks 68, the two clamping plates 3 61 move closer together to clamp the grinding belt 11. Then, the cylinder drives the clamped grinding belt 11 to move upward, so that the top of the grinding belt 11 can contact the bottom surface of the fixing plate 31.

[0046] like Figure 10 and Figure 11As shown, this embodiment provides a specific structure of a clamping and lifting assembly, namely, a clamping and lifting component 7. The clamping and lifting assembly is the clamping and lifting component 7, which includes a fixed base 72 and four clamping plates 71. The four clamping plates 71 are slidably disposed on the fixed base 72. A power component 73 is fixedly disposed on the fixed base 72. The output end of the power component 73 is fixedly connected to a driving helical gear 74. A rotating shaft 75 is drivenly disposed on the fixed base 72. A driven helical gear 76 and two discs 77 are fixedly disposed on the rotating shaft 75. The driving helical gear 74 and the driven helical gear 76 mesh with each other. Two dials 78 are fixedly connected to each of the two discs 77. The four clamping plates 71 are sleeved on the outside of the corresponding dials 78. A power component 79 is fixedly disposed on the fixed base 72. The power component 79 is used to drive the fixed base 72 to move vertically.

[0047] It should be noted that there is only one clamping and lifting component 7, the power component 73 is a motor, the power component 79 is a cylinder, and the clamping plate 71 has a long slot adapted to the dial shaft 78. The motor drives the active helical gear 74 to rotate, which causes the driven helical gear 76 to drive the two discs 77 to rotate through the rotating shaft 75. The discs 77 drive the two dial shafts 78 on the discs 77 to revolve. Thus, while the two discs 77 are rotating, the four dial shafts 78 can move in the corresponding long slots, causing the four dial shafts 78 to move the two clamping plates 71 on the same side closer together, so that they can clamp the grinding belt 11. Then the cylinder drives the clamped grinding belt 11 to move upward, so that the top of the grinding belt 11 can contact the bottom surface of the fixed plate 31.

[0048] Furthermore, two limiting rods are fixedly installed on the fixed base 4 72, and four clamping plates 4 71 are slidably sleeved on the outside of the corresponding limiting rods.

[0049] It should be noted that the limiting rod can provide a vertical limiting effect on the clamping plate 71.

[0050] like Figure 1 As shown, a driving wheel 12 and a driven wheel 13 are rotatably mounted on the grinding mechanism 1. The grinding belt 11 is connected to the driving wheel 12 and the driven wheel 13. A power component 14 is fixedly mounted on the grinding mechanism 1. The output end of the power component 14 is fixedly connected to the driving wheel 12. The power component 14 is used to drive the grinding belt 11 to perform grinding.

[0051] It should be noted that the power component 14 is an electric motor, which drives the drive wheel 12 to rotate and drives the grinding belt 11 through the driven wheel 13 to perform grinding work.

[0052] like Figure 1As shown, a tensioning mechanism 2 is provided on the grinding mechanism 1. The tensioning mechanism 2 includes a power component 21 and a tensioning wheel 22, which are fixedly installed on the grinding mechanism 1. The tensioning wheel 22 is in contact with the grinding belt 11. The power component 21 is used to drive the tensioning wheel 22 to move vertically.

[0053] It should be noted that the second power component 21 is a cylinder. Before measurement, the cylinder drives the tensioning wheel 22 to move downward to tension the grinding belt 11. Then, the clamping and lifting assembly clamps the grinding belt 11, so that the grinding belt 11 is in a straight state when clamped, to avoid the grinding belt 11 being loose and affecting the measurement results. The cylinder drives the tensioning wheel 22 to move upward and separate from the grinding belt 11, so that the grinding belt 11 is in a loose state, so as to lift the grinding belt 11.

[0054] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
