Description

Technical Field

[0001] This invention relates to the field of partition wall panel processing equipment technology, specifically a positioning device for grooving and cutting lightweight partition wall panels. Background Technology

[0002] Lightweight partition boards are widely used in the building decoration industry, but their grooving and cutting operations often face the problem of insufficient positioning accuracy. Traditional positioning methods rely on manual adjustment, which can easily lead to unstable clamping of the partition board, displacement of the grooving position, and difficulty in controlling the depth. In addition, the operation can easily generate a lot of dust and pollute the environment. At the same time, when manually pushing the device to move the grooving, the shaking can affect the cutting quality, resulting in low processing efficiency and low finished product qualification rate.

[0003] Patent publication number CN110900852B relates to a positioning device for grooving and cutting lightweight partition boards. This patent discloses a positioning device for grooving and cutting lightweight partition boards, including a fixing mechanism, a first support column, a second support column, a support crossbar, a movable collar, a square fixing ring, a positioning plate, a locking mechanism, a wall-mounted panel, and a clamping mechanism. This positioning device for grooving and cutting ceramsite wall boards, through the cooperation of the support crossbar, positioning plate, locking mechanism, fixing mechanism, and clamping mechanism, makes grooving more convenient for workers. It can assist in marking lines, improving work efficiency, and also supports the grooving machine, reducing the labor intensity of workers. Furthermore, it limits the grooving machine, enabling it to be positioned correctly for grooving, resulting in better grooving. It solves the problem that when using a handheld grooving machine, generally, lines are first drawn, and then grooving is done along the lines. However, because handheld grooving machines are mostly heavy, it is very inconvenient for workers to cut horizontal grooves. On the one hand, the grooving machine is prone to deviation, resulting in crooked grooves; on the other hand, workers' hands become sore after holding it for a long time, increasing the burden on workers.

[0004] Although this patent solves the problem of easy deviation of the grooving machine, when the partition wall needs to be grooved a second time, the manual clamping action needs to be repeated, which increases the workload and reduces the efficiency of grooving. Therefore, a lightweight positioning device for grooving and cutting partition wall is designed to be easy to move. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a positioning device for grooving and cutting lightweight partition boards, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a positioning device for grooving and cutting lightweight partition boards, comprising a positioning device, an adjustment device and a grooving device; The positioning device includes an electric telescopic rod. A first fixing plate is fixedly installed on the side of the output end of the electric telescopic rod. A second fixing plate is fixedly installed on the side of the first fixing plate. A fixing rod is fixedly installed on the side of the second fixing plate. A caster wheel is provided at the lower end of the fixing rod.

A disc is fixedly installed below the rotating shaft. A third fixing plate is fixedly installed on the side of the fixing rod. A first groove is provided on the second fixing plate. A transmission rod is provided in the first groove. A first roller is rotatably installed on the side of the transmission rod. When the electric telescopic rod is started, the output end of the electric telescopic rod drives the first fixing plate to move to the left. The first fixing plate drives the second fixing plate to move to the left. The second fixing plate drives the rotating shaft, the transmission rod, the fixing rod, and the third fixing plate to move to the left.

[0007] Preferably, the positioning device is provided in two parts, except for the electric telescopic rod, and is symmetrically arranged on both sides of the electric telescopic rod. When the electric telescopic rod is retracted, the cylinder clamps and positions the two sides of the partition wall. At this time, although the partition wall is clamped from left to right, it can move back and forth.

[0008] Preferably, the adjusting device includes a threaded rod rotatably mounted on a fixed plate two. A turntable is fixedly mounted on the threaded rod, and a block is rotatably mounted below the threaded rod. A motor one is fixedly mounted on the side of the block, and a roller two is fixedly mounted on the side of the output end of the motor one. A triangular block one is fixedly mounted on the side of the block. A groove two is formed on the side of the transmission rod, and a long plate is slidably mounted in the groove two. Multiple triangular blocks two are fixedly mounted on the side of the long plate. A fixing member is fixedly mounted on the fixed plate two, and an L-shaped plate is fixedly mounted on the circumference of the fixing member. A stop block is fixedly mounted on the L-shaped plate. When the turntable is rotated, the turntable drives the threaded rod to rotate and move downward. The threaded rod drives the block to move downward, and the block drives the motor one and the triangular block one to move downward. The downward movement of the triangular block one and its contact with the triangular block two will not have any impact.

[0009] Preferably, the threaded rod is threadedly connected to the fixed plate two, and multiple springs are provided between the groove two and the long plate. The triangular block two drives the long plate to move upward, the long plate drives the transmission rod to move upward, and the transmission rod drives the roller one to move upward.

[0010] Preferably, a third groove is provided on one side of the first groove. The third groove is on the movement trajectory of the stop block. When the L-shaped plate is rotated clockwise, the L-shaped piece drives the stop block to insert into the third groove. The stop block contacts the second triangular block. After being pushed by the stop block, the second triangular block drives the long plate to slide to the left in the second groove, and the second triangular block separates from the first triangular block.

[0011] Preferably, the grooving device includes a hollow tube, which is fixedly installed on both sides of a fixed plate. A square tube is slidably installed inside the hollow tube. A toothed block 1 is provided on the side of the hollow tube, and a toothed block 2 is provided on the top and bottom of the square tube. A pulley 1 is provided on the side of the toothed block 2. A U-shaped component is rotatably installed on the pulley 1. A pulley 2 is rotatably installed on the circumferential surface of the U-shaped component. A frame is fixedly installed on the circumferential surface of the U-shaped component. A shell is fitted onto the frame. A handle is fixedly installed on the side of the shell. A motor 2 is fixedly installed below the shell. A circular box is fixedly installed below the motor 2. A circular component is fixedly installed below the output end of the motor 2. A tube is provided between the circular box and the shell. The fixed plate 2 drives the hollow tube to move to the left, and the hollow tube and the square tube form a long track. The motor 2 is started, and the output end of the motor 2 drives the circular component to rotate.

[0012] Preferably, the second toothed block is mounted on the inner wall of the hollow tube and slides. A nozzle is provided below the round box. The output end of the second motor rotates through the center of the round box. After the water pipe is connected to the outside of the tube, the water flows into the round box through the pipe and then flows out from the nozzle, preventing dust from being generated during the grooving process.

[0013] Preferably, the circular component has toothed blocks three on both its bottom and circumferential surfaces. A water pipe is connected to the outside of the pipe. The output end of the second motor drives the circular component to rotate, and the circular component drives the toothed blocks three to rotate, thus creating grooves on the surface of the partition wall.

[0014] This invention provides a positioning device for grooving and cutting lightweight partition boards. It has the following advantages:

[0015] (1) After the electric telescopic rod is started, the power is transmitted through the first fixed plate and the second fixed plate in sequence, which synchronously drives the rotating shaft, the transmission rod, the fixed rod and the third fixed plate to move, ensuring that all components work together. The fixed rod drives the universal wheel to slide, the rotating shaft drives the cylinder and the transmission rod drives the first roller to move, which facilitates the adjustment of the partition wall position. After the partition wall is placed on the first roller and the electric telescopic rod is retracted, the cylinder can clamp and position the two sides of the partition wall.

[0016] (2) In this positioning device, the rotating turntable drives the square block, motor one and triangular block one to move through the threaded rod. Motor one drives roller two to form an upper and lower clamp with roller one. Control motor one to make roller two drive the partition board to move back and forth. Cooperate with fixed plate three to scrape off the side. Rotate the turntable in the opposite direction. Triangular block one drives triangular block two, long plate and transmission rod to move. Roller one adjusts the upper and lower position of the partition board, which is convenient for setting the groove depth and can be adapted to partition boards of different thicknesses.

[0017] (3) In this positioning device, the fixed plate 2 drives the hollow tube and the square tube to form a long track, providing a trajectory for the grooving device to move left and right. When the motor 2 is started, its output end drives the circular part and the toothed block 3 to rotate, which can grooving the surface of the partition board. Combined with the up and down position adjustment of the partition board, the grooving depth can be precisely controlled. Pushing the handle can drive the outer shell, frame and U-shaped part to move. The U-shaped part drives the pulley 1 and pulley 2 to slide the toothed block 1 and toothed block 2. Multiple pairs of pulley groups can prevent the device from shaking when sliding. After the water pipe is connected to the outside of the pipe, the water flows through the round box and flows out from the nozzle, which can effectively prevent dust from being generated during grooving.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-11 One embodiment of the present invention is: a positioning device for grooving and cutting lightweight partition boards. The positioning device includes a positioning device, an adjusting device, and a grooving device. The positioning device includes an electric telescopic rod 1. A fixing plate 101 is fixedly installed on the side of the output end of the electric telescopic rod 1. A fixing plate 102 is fixedly installed on the side of the fixing plate 101. A fixing rod 103 is fixedly installed on the side of the fixing plate 102. A caster wheel 104 is rotatably installed at the end of the fixing rod 103 away from the fixing rod 103. A rotating shaft 105 is fixedly installed below the fixing plate 102. A cylinder 106 is rotatably installed on the circumference of the rotating shaft 105. A disc 107 is fixedly installed below the rotating shaft 105. The fixing rod 104... 3. A fixing plate 3 108 is fixedly installed on the side. A groove 1 is opened on the fixing plate 2 102. A transmission rod 109 is set in the groove 1. A roller 110 is rotatably installed on the side of the transmission rod 109. When the electric telescopic rod 1 is started, the output end of the electric telescopic rod 1 drives the fixing plate 1 101 to move to the left. The fixing plate 1 101 drives the fixing plate 2 102 to move to the left. The fixing plate 2 102 drives the rotating shaft 105, the transmission rod 109, the fixing rod 103 and the fixing plate 3 108 to move to the left. After the electric telescopic rod 1 is driven, the power is transmitted through the fixing plate 1 101 and the fixing plate 2 102 in sequence, which synchronously drives the rotating shaft 105, the transmission rod 109, the fixing rod 103 and the fixing plate 3 108 to move, ensuring that all components work together.

[0032] The positioning device is provided in two parts except for the electric telescopic rod 1, and is symmetrically arranged on both sides of the electric telescopic rod 1. When the electric telescopic rod 1 is retracted, the cylinder 106 clamps and positions the two sides of the partition wall. At this time, although the partition wall is clamped from left to right, it can move back and forth. After the electric telescopic rod 1 is retracted, the cylinder 106 can clamp and position the two sides of the partition wall.

[0033] In this embodiment, during operation: The electric telescopic rod 1 is activated. The output end of the electric telescopic rod 1 drives the first fixed plate 101 to move to the left. The first fixed plate 101 drives the second fixed plate 102 to move to the left. The second fixed plate 102 drives the rotating shaft 105, the transmission rod 109, the fixed rod 103, and the third fixed plate 108 to move to the left. The fixed rod 103 drives the universal wheel 104 to slide to the left. The rotating shaft 105 drives the cylinder 106 to move to the left. The transmission rod 109 drives the first roller 110 to move to the left, placing the partition board on the first roller 110. At this time, the electric telescopic rod 1 is retracted. After the electric telescopic rod 1 is retracted, the cylinder 106 clamps and positions the partition board on both sides. Although the partition board is clamped on both sides, it can move back and forth. During the movement, the third fixed plate 108 scrapes the left and right sides of the partition board, which can prevent the partition board from tilting after clamping due to some rough edges during the positioning process.

[0034] Please see Figures 1-11 Based on the above embodiments, in another embodiment of the present invention, the adjusting device includes a threaded rod 2, which is rotatably mounted on a fixed plate 102. A turntable 201 is fixedly mounted on the threaded rod 2, and a block 202 is rotatably mounted below the threaded rod 2. A motor 203 is fixedly mounted on the side of the block 202, and a roller 204 is fixedly mounted on the side of the output end of the motor 203. A triangular block 205 is fixedly mounted on the side of the block 202. A groove 2 is provided on the side of the transmission rod 109, and a long plate 206 is slidably mounted in the groove 2. Multiple triangular blocks 207 are fixedly mounted on the side of the long plate 206. A fixed plate 207 is mounted on the top of the fixed plate 102. A fixing component 208 is installed, and an L-shaped plate 209 is fixedly installed on the circumference of the fixing component 208. A stop block 210 is fixedly installed on the L-shaped plate 209. When the turntable 201 is rotated, the turntable 201 drives the threaded rod 2 to rotate and move downward. The threaded rod 2 drives the block 202 to move downward. The block 202 drives the motor 1 203 and the triangular block 1 205 to move downward. The downward movement of the triangular block 1 205 will not affect the contact with the triangular block 207. The rotation of the turntable 201 drives the block 202, the motor 1 203 and the triangular block 1 205 to move through the threaded rod 2. The motor 1 203 drives the roller 2 204 and the roller 1 110 to form an upper and lower clamp.

[0035] The threaded rod 2 is threadedly connected to the fixed plate 102. Multiple springs are installed between the groove 2 and the long plate 206. The triangular block 207 drives the long plate 206 to move upward. The long plate 206 drives the transmission rod 109 to move upward. The transmission rod 109 drives the roller 110 to move upward. The control motor 203 causes the roller 204 to drive the partition plate to move back and forth, which works with the fixed plate 108 to scrape the side.

[0036] A groove three is provided on one side of the groove. The groove three is on the movement trajectory of the stop block 210. The L-shaped part drives the stop block 210 to insert into the groove three. The stop block 210 releases the triangular block two 207. The triangular block two 207 drives the long plate 206 to slide to the left. The triangular block two 207 disengages from the triangular block one 205. The transmission rod 109 slides down and rotates the turntable 201 in the opposite direction. The triangular block one 205 drives the triangular block two 207, the long plate 206 and the transmission rod 109 to move, so that the roller one 110 can adjust the upper and lower positions of the partition wall, which is convenient for setting the groove depth and can adapt to partition wall panels of different thicknesses.

[0037] In this embodiment, during operation: Rotating turntable 201 causes the threaded rod 2 to rotate and move downwards. The threaded rod 2 then moves block 202 downwards. Block 202 drives motor 1 203 and triangular block 1 205 downwards. Triangular block 1 205's downward movement and contact with triangular block 2 207 will not cause any impact. Motor 1 203 drives roller 2 204 downwards to press the upper surface of the partition wall panel, forming a clamping action with roller 1 110. Controlling motor 1 203 to rotate causes roller 2 204 to move the partition wall panel back and forth. Simultaneously, this back-and-forth movement creates grooves and scrapes away rough edges on the side of the partition wall panel using fixing plate 3 108. When adjusting the partition wall panel's position, rotating turntable 201 in the opposite direction causes block 202 to rise, driving triangular block 1 205 upwards. Triangular block 1 205's upward movement drives triangular block 2 207 upwards, which in turn drives the long... The plate 206 moves upward, and the long plate 206 drives the transmission rod 109 to move upward. The transmission rod 109 drives the roller 110 to move upward, thereby adjusting the upper and lower positions of the partition wall to facilitate setting the groove depth. When the partition wall needs to be lowered, the L-shaped plate 209 is rotated 180 degrees clockwise. The L-shaped part drives the stop block 210 to insert into the groove three. The stop block 210 contacts the triangular block 207. After being pushed by the stop block 210, the triangular block 207 drives the long plate 206 to slide to the left in the groove two. The triangular block 207 disengages from the triangular block 1 205, and the transmission rod 109 is no longer limited by the triangular block 1 205 to slide down. The partition wall and the transmission rod 109 fall together. When the partition wall is thick, the stop block 210 can be inserted directly. When the partition wall is thin, the turntable 201 needs to be rotated. When the triangular block 1 205 and the triangular block 207 are below the fixed plate 2 102, they can be inserted.

[0038] Please see Figures 1-11Based on the above embodiments, in another embodiment of the present invention, the grooving device includes a hollow tube 3, which is fixedly installed on the side of the fixing plate 102. A square tube 301 is slidably installed inside the hollow tube 3. A toothed block 1 is provided on the side of the hollow tube 3, and a toothed block 2 is provided on the upper and lower surfaces of the square tube 301. A pulley 302 is provided on the side of the toothed block 2. A U-shaped part 303 is rotatably installed on the pulley 302. A pulley 304 is rotatably installed on the circumferential surface of the U-shaped part 303. A frame 305 is fixedly installed on the circumferential surface of the U-shaped part 303. A shell 306 is sleeved on the frame 305. A handle 307 is fixedly installed on the side of the shell 306. A handle 307 is fixedly installed on the lower surface of the shell 306. A motor 308 is fixedly installed, and a circular box 309 is fixedly installed below the motor 308. A circular component 310 is fixedly installed below the output end of the motor 308. A tube 311 is provided between the circular box 309 and the outer shell 306. The fixed plate 102 drives the hollow tube 3 to move to the left, and the hollow tube 3 and the square tube 301 form a long track. When the motor 308 is started, the output end of the motor 308 drives the circular component 310 to rotate. The fixed plate 102 drives the hollow tube 3 and the square tube 301 to form a long track, providing a trajectory for the grooving device to move left and right. When the motor 308 is started, its output end drives the circular component 310 and the toothed block 3 to rotate, which can grooving the surface of the partition wall.

[0039] The second toothed block slides on the inner wall of the hollow tube 3. A nozzle is provided below the round box 309. The output end of the second motor 308 rotates through the middle of the round box 309. After the water pipe is connected to the outside of the pipe 311, the water flows into the round box 309 along the pipe 311 and then flows out from the nozzle, preventing dust from being generated during the grooving process. Combined with the adjustment of the upper and lower positions of the partition plate, the grooving depth can be precisely controlled. Pushing the handle 307 can drive the outer shell 306, frame 305, and U-shaped part 303 to move. The U-shaped part 303 drives the pulley 1 302 and pulley 2 304 to slide against the toothed block 1 and toothed block 2. Multiple pairs of pulleys can prevent the device from shaking when sliding.

[0040] The circular component 310 has toothed blocks on both its bottom and circumferential surfaces. A water pipe is connected to the outside of the pipe 311. The output end of the motor 308 drives the circular component 310 to rotate, which in turn drives the toothed blocks to rotate, thus creating grooves on the surface of the partition wall. After the water pipe is connected to the outside of the pipe 311, the water flows through the circular box 309 and out of the nozzle, which can effectively prevent dust from being generated during the grooving process.

[0041] In this embodiment, during operation: the fixed plate 102 drives the hollow tube 3 to move to the left, forming a long track with the square tube 301. The motor 308 is started, and the output end of the motor 308 drives the circular part 310 to rotate. The circular part 310 drives the toothed block 3 to rotate, thus slotting the surface of the partition board. The vertical position of the partition board is adjusted to control the slotting depth. If left or right slotting is required, the handle 307 is pushed. The handle 307 drives the outer shell 306 to move, the outer shell 306 drives the frame 305 to move, and the frame 305 drives the U-shaped part 303 to move. The U-shaped part 303 drives the pulley 302 and pulley 304 to slide against the toothed block 1 and toothed block 2. Multiple pairs of pulleys ensure that the device will not shake during the sliding process, thus enabling left and right slotting. After the water pipe is connected to the pipe 311, the water flows into the circular box 309 along the pipe 311 and then flows out from the nozzle, preventing dust from being generated during the slotting process.
