Description

Technical Field

[0001] The invention relates to the technical field of decoration slotting equipment, in particular to a wall wire slot slotting and cutting machine for decoration. Background Art

[0002] In the decoration of modern homes and commercial spaces, in order to hide wires, pipes and other facilities, it is often necessary to open cable troughs on the walls. The traditional grooving method relies on some semi-automatic or fully automatic wall grooving equipment, which can increase the grooving speed and reduce the workload of workers. However, when workers are performing grooving construction, the cutting machines or electric picks they use will generate a lot of dust during use, causing the workers' working environment to become very bad, and will also affect the construction environment.

[0003] The Chinese invention patent with announcement number: CN112060373B discloses a construction grooving device, which uses a grooving mechanism to cut and crush the wire grooves at one time, and uses a grooving wheel to knock and crush the wire grooves cut by the cutting blade and the connecting blade, so that construction workers do not need to knock the wire grooves for a second time, thereby improving the work efficiency of construction workers. The protective mechanism uses a dust suction mechanism to absorb the dust generated by the high-speed rotation friction between the grooving mechanism and the wall, and the dust suction mechanism sends the dust into the dust filter cylinder. The dust filter cylinder uses the design between the No. 1 cross and the No. 2 cross to increase the processing space of the cylinder for dust filtration, thereby avoiding clogging of the filter screen and affecting the purification of dust.

[0004] The existing device or the above-mentioned technology integrates the cutting blade of the slotting machine so that the integral wire groove can be cut directly, but does not consider whether the heat of the cutting blade can be dissipated during the cutting process, or the problem of cutting speed during the cutting process.

[0029] like Figure 2 , Figure 6 , Figure 7 As shown, a partition plate 104 is also fixedly installed in the fuselage 101, and the partition plate 104 is fixedly connected to the power box 105. A swing frame 309 is rotatably installed at one end of the partition plate 104 away from the power box 105, and swing springs 310 are fixedly installed on both sides of the swing frame 309.

The end of the sliding column 306 away from the pick head is provided in the fixed cylinder 304. A return spring 305 is fixedly installed in the fixed cylinder 304, and the other end of the return spring 305 is fixedly installed on the sliding column 306 to limit the position of the sliding column 306.

A connecting rod 302 is rotatably installed on the collision plug 303, and a driving wheel 301 is rotatably installed on the connecting rod 302. The connection between the driving wheel 301 and the connecting rod 302 is eccentrically arranged. The driving wheel 301 is rotatably connected to the fuselage 101. An electric pick motor is arranged in the fuselage 101. The output shaft of the electric pick motor is fixedly connected to the driving wheel 301 to drive the driving wheel 301 to rotate. When the driving wheel 301 rotates, the sliding column 306 can be driven to reciprocate on the fixed cylinder 304 and the limiting frame 307 through the collision plug 303. like Figure 2 , Figure 6 , Figure 7As shown, a limit screw 103 is provided on the fuselage 101, and the limit screw 103 is connected to the fuselage 101 by a thread, and a rotating handle is provided at one end of the limit screw 103 outside the fuselage 101, and an extrusion plate 308 is provided at one end of the limit screw 103 inside the fuselage 101, and the extrusion plate 308 can contact with the swing frame 309, and the extrusion plate 308 is used to limit the swing range of the swing frame 309. The user can adjust the position of the extrusion plate 308 by rotating the rotating handle on the limit screw 103, thereby changing the rotation angle of the swing frame 309.

[0030] like Figures 1 to 3 and Fig. 9 As shown, a main slide 402 is slidably mounted on the front cover shell 106, and the main slide 402 is also slidably connected to the fuselage 101, and the multiple main slides 402 are symmetrically arranged, and a side resistance frame 401 is also slidably mounted on the side cover shell 205, and a rolling wheel 403 is rotatably mounted on the outer side of the side resistance frame 401, and the rolling wheel 403 is made of rubber material, and the side resistance frame 401 and the main slide 402 are both provided with wear-resistant strips at one end away from the fuselage 101, and the main slide 402 and the side resistance frame 401 are both provided with a filter 404, and the filter 404 is made of polyester needle felt, and the filter 404 is used to reduce dust emission, and the filter 404 is arranged in a foldable form, and the fuselage 101, the front cover shell 106 and the multiple filters 404 form a dust blocking chamber, and the dust in this chamber cannot pass through the filter 404, thereby improving the user's working environment.

[0031] Working principle: When the device is in use, the user holds the handle 102 with his hand, and then rotates the limit screw 103. First, the extrusion plate 308 on the limit screw 103 is moved away from the swing frame 309. After the extrusion plate 308 moves to the limit position away from the swing frame 309, the swing angle of the swing frame 309 is also the largest at this time. This is to allow the sliding column 306 to have a swing space, so that the side resistance frame 401 and the main slide frame 402 on the device can be attached to the wall later. When the cutting blade 210 penetrates into the wall for cutting, the sliding column 306 will not limit the movement of the cutting blade 210 After adjusting the position of the extrusion plate 308, the device can also rotate the adjusting drum 202 to drive the width screw 203 after the adjusting drum 202 rotates, and then the width screw 203 drives the side cover 205 to move, thereby adjusting the position of the cutting blade 210 on the main shaft 207, and when the main shaft 207 moves, the side resistance frame 401 will also move together, thus completing the width adjustment of the cutting groove, and the ash blocking chamber will be adjusted at the same time as the width is adjusted, and then the side resistance frame 401 and the main slide 402 of the device are set with one end of the wear-resistant strip in contact with the wall, and then the cutting work can be started.

[0032] When the device is cutting, it is necessary to start the cutting motor 201 first, so that the cutting motor 201 drives the main shaft 207 to rotate through the toothed belt 216, the intermediate shaft 217, the transmission gear 215, and the main shaft gear 214, and the main shaft 207 drives the cutting blade 210 to rotate. After the cutting blade 210 rotates, the user can press the device to move the cutting blade 210 into the wall, so that the wall can be cut by the rotation of the cutting blade 210. At this time, the filter screen 404 on the side blocking frame 401 and the main slide 402 will gradually fold up, and when the cutting blade 210 is cutting, the airflow driven by the cutting blade 210 will carry a large amount of dust generated after the cutting blade 210 cuts. When these airflows pass through the filter screen 404, the filter screen 404 will block them in the dust blocking chamber, so that the dust can be controlled in the device, thereby improving the working environment.

[0033] When the cutting blade 210 of the present device is cutting, the sliding column 306 can also be used to directly impact and crush the cut wall. At this time, the electric pick motor is started to drive the driving wheel 301 to rotate. The driving wheel 301 can drive the collision plug 303 to slide in the fixed cylinder 304 through the connecting rod 302. When the collision plug 303 slides, the collision plug 303 will hit one end of the sliding column 306 in the fixed cylinder 304, so as to drive the pick head on the sliding column 306 to impact the cut wall. When the impact is in progress, the reset spring 305 will also be stretched for the subsequent reset movement of the sliding column 306. When the impact and crushing are in progress, the user can also adjust the position of the extrusion plate 308 by rotating the limit screw 103, thereby changing the swing state of the swing frame 309. The purpose of this is to change the impact angle and impact depth of the pick head on the sliding column 306.
