Description

Technical Field

[0001] This application relates to the field of grooving tools, and in particular to a grooving tool for interior decoration. Background Technology

[0002] As a tool that uses a high-speed rotating blade to cut objects, the cutting machine is widely used in various fields due to its simple operation and low cost. In the grooving of interior decoration, it is necessary to first draw auxiliary lines on the wall and then cut the auxiliary lines with a cutting machine. In this process, the water pipes that are inserted after grooving often protrude from the surface of the wall due to the improper control of the depth and distance by the cutting personnel, which requires grooving again, wasting time and manpower. During the grooving process, a lot of dust is generated, which requires the grooving personnel to wear masks to work, and it also makes the construction site dirty. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this application provides a grooving tool for interior decoration, which can effectively solve the above problems.

[0004] The technical solution adopted by this application to solve its technical problem is: a grooving tool for interior decoration, including a cutting machine and a dust collection bag. The cutting machine includes a fixed part and a moving part. The moving part can move left and right on the fixed part. A distance measuring device is provided on the fixed part. A handle is provided on the moving part. The handle is used to pull the moving part backward and trigger a switch provided on the fixed part. A locking device is provided between the fixed part and the moving part. When the locking device is triggered, a sealed space is formed between the moving part and the wall. When the locking device is triggered, it drives a reset rod to move. A bimetallic strip is provided on the moving part. The bimetallic strip is used to drive a dust collection device provided on the moving part. The dust collection device is provided with a replacement device for automatically replacing the dust collection bag.

[0005] In the above technical solution, the fixed part is further connected to the motor, the motor is located outside the moving part, a hinge is provided at the connection between the motor and the moving part, a spring is provided between the handle and the fixed part, and a sliding groove is provided on the moving part, which cooperates with the bearing sleeved on the outside of the main shaft. When the moving part is in operation, the sliding groove moves on the bearing.

[0006] In the above technical solution, the locking device further includes a cam and a wedge block. The cam is connected to a fixed shaft, and the cam has a groove that connects to the reset rod. The wedge block has gear teeth. When the locking device is triggered, the cam pushes the wedge block upward, and the gear teeth mesh with the rack on the fixed part and push the reset rod backward.

[0007] In the above technical solution, further, when the cutting machine is cutting the wall, it activates the bimetallic strip. The bimetallic strip is connected to the push rod, and the push rod is equipped with a gear. When the bimetallic strip is activated, it moves the push rod backward, so that the gear meshes with the main shaft and the fan, thereby causing the main shaft to drive the dust collection device to start.

[0008] In the above technical solution, further, after the bimetallic strip is activated, when the switch is triggered again, the push rod will trigger the rotating part, which is sleeved on the fixed part, and the upper end of the rotating part will be shifted forward, so that the rotating part pushes the reset rod to push the cam out, at which time the locking device is reset.

[0009] In the above technical solution, the dust collection device further includes the fan disposed on the moving part, a dust outlet is provided between the fan and the moving part, and the dust collection bag is installed at the dust outlet.

[0010] In the above technical solution, the replacement device further includes an inclined groove disposed on the outside of the moving part. The inclined groove can accommodate multiple dust collection bags. A stop block is disposed at the end of the inclined groove. A torsion spring is disposed between the stop block and the inclined groove. The stop block opens after the dust collection bag has collected a certain amount of dust, so that the dust collection bag falls off and is replaced by the next dust collection bag.

[0011] The beneficial effects of this application are as follows: It provides a grooving tool for interior decoration, which is equipped with a distance measuring device to measure the depth of the blade in the wall, and a locking device. After the distance is measured, the locking device can be activated to lock the moving part on the fixed part. The moving part is close to the wall surface when cutting, so that the cutting depth of the blade in the wall is uniform and a sealed space is formed in the moving part. It is equipped with a dust collection device to suck the dust generated during cutting into the dust collection bag, and a replacement device to automatically replace the dust collection bag.

[0020] Please refer to Figure 1-6 The following is a specific embodiment of this application: A grooving tool for interior decoration includes a cutting machine 1 and a dust collection bag 2. The cutting machine 1 includes a fixed part 3 and a moving part 4. The moving part 4 is made of transparent material to facilitate observation of the position of the cutting auxiliary line and the internal condition of the cutting machine 1. The moving part 4 can move left and right on the fixed part 3. A distance measuring device 5 is provided on the fixed part 3, including a camera 51 and a display screen 52. The distance measuring device 5 is used to measure the distance between the blade 12 and the wall. A handle is provided on the moving part 4. 41. The handle 41 is used to pull the moving part 4 backward and trigger the switch 31 provided on the fixed part 3. A locking device 6 is provided between the fixed part 3 and the moving part 4. When the locking device 6 is triggered, a sealed space is formed between the moving part 4 and the wall. When the locking device 6 is triggered, it drives the reset rod 61 to move. A bimetallic strip 71 is provided on the moving part 4. The bimetallic strip 71 is used to drive a dust collection device 7 provided on the moving part 4. The dust collection device 7 is provided with a replacement device 8 for automatically replacing the dust collection bag 2.

[0021] The fixed part 3 is connected to the motor 11, so that the position of the blade 12 is fixed. The motor 11 is located outside the moving part 4. A hinge 42 is provided at the connection between the motor 11 and the moving part 4, which can keep the internal space of the moving part 4 sealed when it is in operation. A spring 32 is provided between the handle 41 and the fixed part 3. A sliding groove 43 is provided on the moving part 4, which cooperates with the bearing 44 sleeved on the outside of the main shaft. When the moving part 4 is in operation, the sliding groove 43 moves on the bearing 44. When the handle 41 is pulled backward, the moving part 4 moves backward, so that the blade 12 is exposed in the moving part to the maximum depth of the cutting machine 1.

[0022] Specifically, in order to achieve a uniform cutting depth during the cutting process, a locking device 6 is provided, including a cam 62, a wedge block 63, and a locking block 64 for fixing the position below the wedge block 63. The cam 62 is connected to the fixed shaft 65 and initially protrudes from the surface of the moving part 4. The cam 62 is provided with a groove 66 that connects to the reset rod 61. The wedge block is provided with gear teeth 631. When the locking device 6 is triggered, the cam 62 retracts into the moving part 4, and the cam 62 pushes the wedge block 63 upward. The gear teeth 631 mesh with the rack 33 provided on the fixed part 3 and push the reset rod 61 backward.

[0023] Specifically, in order to activate the dust collection device 7 when cutting the wall, the cutting machine 1 activates the bimetallic strip 71 when cutting the wall. The bimetallic strip 71 is set to change its state when it reaches 100 degrees Celsius. Its initial state is protruding to the left. The bimetallic strip 71 is connected to the push rod 72. The push rod 72 is equipped with a gear 73. When the blade 12 contacts the wall, it generates high temperature. When the bimetallic strip 71 is activated, it moves the push rod 72 backward, so that the gear 73 meshes with the main shaft and the fan 74, thereby causing the main shaft to drive the dust collection device 7 to start.

[0024] Specifically, in order to reset the device after cutting, when the switch 31 is triggered again after the bimetallic strip 71 is activated, the push rod 72 moves backward, which triggers the rotating part 34, pushing the rear end of the rotating part 34 backward. The rotating part 34 is sleeved on the fixed part 3. When the upper end of the rotating part 34 is shifted forward and the moving part 4 is pulled backward, the front end of the rotating part 34 will contact the reset rod 61, causing the rotating part 4 to push the reset rod 61 to push the cam 62 out. At this time, the locking device 6 is reset.

[0025] In order to absorb the dust generated during cutting within the moving part 4, a dust collection device 7 is provided, including a fan 74 mounted on the moving part 4, a transmission bar 75 mounted on the slide groove 43, and a transmission gear 76 mounted on the moving part 4. The transmission bar 75 meshes with the main shaft and the transmission gear 76, enabling the main shaft to drive the transmission gear 76 to rotate. A dust outlet 45 is provided between the fan 74 and the moving part 4, and the dust collection bag 2 is installed at the dust outlet 45.

[0026] Furthermore, in order to achieve automatic replacement of the dust collection bag 2, a replacement device 8 is provided, including an inclined groove 81 located on the outside of the moving part 4. The inclined groove 81 can accommodate multiple dust collection bags 2. A stop block 82 is provided at the end of the inclined groove 81. A torsion spring 83 is provided between the stop block 82 and the inclined groove 81. The stop block 82 opens after the dust collection bag 2 has collected a certain amount of dust, allowing the dust collection bag 2 to fall off and be replaced by the next dust collection bag 2. When the dust collection bag 2 has collected two-thirds of the dust, its gravity causes the stop block 82 to move to both sides. After the dust collection bag 2 falls off, the stop block returns to its original position.

[0027] Working process: During construction, pull the handle 41 backward to move the moving part 4 to its maximum distance, triggering the switch 31. At this time, start the cutting machine 1, then align the blade 12 with the auxiliary line and push it inward while observing the display screen 52. At this time, start the dust collection device 7 and drive the push rod 72 to move backward. When the required depth is reached, release the handle 41, allowing the moving part 4 to move forward and contact the wall, triggering the locking device 6 to fix the moving part 4 to the fixed part 3. At this time, drive the reset rod 61 to move backward. When the dust bag 2 has collected a certain amount of dust, start the replacement device 8 to remove the current dust bag 2 and replace it with a spare dust bag 2. After construction is completed, pull the handle 41 again to trigger the switch 31. At this time, the cutting machine 1 stops, and the reset rod 61 contacts the rotating part 34 to reset the device.
