Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a thickness detection mechanism and a bidirectional automatic grooving machine. Background Technology

[0002] In the panel processing industry, such as the production of building panels and furniture panels, grooving is an important process. The depth and positional accuracy of the grooving directly affect the quality of subsequent processes such as splicing and assembly of the panels.

[0003] Existing thickness detection mechanisms and bidirectional automatic grooving machines still have some shortcomings in practical use: 1. Most existing grooving machines on the market have only one function and can only perform unidirectional grooving operations. For plates that require bidirectional grooving, manual secondary clamping and adjustment are required, which not only results in low production efficiency, but also makes it difficult to guarantee the accuracy and consistency of bidirectional grooving due to the uncertainty of manual operation.

[0004] 2. The thickness of the board may have some errors or fluctuations. Traditional grooving machines lack an effective thickness detection mechanism and cannot obtain the thickness information of the board in real time. This makes it difficult to accurately control the grooving depth, which can easily lead to problems such as grooving too deep or too shallow, affecting the performance and processing quality of the board. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies that can only perform unidirectional grooving operations. For boards requiring bidirectional grooving, manual secondary clamping and adjustment are necessary, resulting in low production efficiency. Furthermore, due to the uncertainty of manual operation, it is difficult to guarantee the accuracy and consistency of bidirectional grooving. Traditional grooving machines lack an effective thickness detection mechanism, making it impossible to obtain the thickness information of the board in real time. This leads to difficulty in accurately controlling the grooving depth, resulting in problems such as grooving that is too deep or too shallow, affecting the performance and processing quality of the board. Therefore, this invention proposes a thickness detection mechanism and a bidirectional automatic grooving machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A thickness detection mechanism and a bidirectional automatic grooving machine include a frame, a U-shaped frame fixedly installed on the top of the frame, a sliding frame slidably connected inside the U-shaped frame, a sliding block slidably connected inside the sliding frame, a connecting column slidably passing through the sliding block, a spring sleeved on the outer wall of the connecting column, a movable wheel fixedly connected to the bottom of the connecting column, and the top and bottom of the spring fixedly connected to the bottom of the sliding block and the top of the movable wheel, respectively. A proximity sensor is fixedly connected to the inner top wall of the sliding frame, and the proximity sensor is located above the connecting column.

[0007] In one possible design, a reciprocating lead screw is rotatably connected inside the U-shaped frame, the reciprocating lead screw passes through a sliding frame, a connecting frame is fixedly connected inside the sliding frame, and a slider is fixedly connected inside the connecting frame, with the slider sliding in the helical groove on the outer wall of the reciprocating lead screw.

[0008] In one possible design, the frame is provided with multiple conveying rollers, each of which is fixedly connected to a support wheel at both ends. The support wheel is rotatably connected to the frame via a rotating shaft. A grooved wheel is fixedly fitted on the outer wall of the rotating shaft of the support wheel at one end of one of the conveying rollers. A second drive motor is fixedly installed on the inner wall of one side of the frame, and the rotating shaft of the second drive motor extends through one side of the frame. A cylindrical pin is fixedly fitted on the outer wall of the rotating shaft of the second drive motor, and the grooved wheel and the cylindrical pin are rotatably engaged.

[0009] In one possible design, double-row sprockets are fixedly fitted on the outer wall of the rotating shaft of the support wheel at the other end of multiple conveying rollers, and adjacent double-row sprockets are connected by sprocket drive.

[0010] A bidirectional automatic grooving machine includes a thickness detection mechanism and a top frame fixedly installed on the top of the machine frame. The top frame contains two push frames arranged in a cross-shaped staggered configuration. One end of each push frame is fixedly connected to a mating block, and the other end of each push frame is fixedly connected to a nut. Both the push frames and the nuts slide within the top frame. Two lead screws are rotatably connected within the top frame, and each lead screw is threaded through a nut. Two third drive motors are fixedly installed within the top frame, and one end of each lead screw is fixedly connected to one end of the rotating shaft of each of the two third drive motors. The two push frames are slidably connected to the same mounting bracket.

[0011] In one possible design, a servo motor is provided at the bottom of the mounting bracket, a mounting frame is provided inside the mounting bracket and slides through to the bottom of the mounting bracket, and the servo motor is fixedly installed at the bottom of the mounting frame. A lead screw is rotatably connected inside the mounting bracket, and the mounting frame is threaded onto the outer wall of the lead screw. A fourth drive motor is fixedly connected inside the mounting bracket, and gears are fixedly fitted on the outer wall of the rotating shaft of the fourth drive motor and the top of the mounting frame, and the two gears mesh with each other.

[0012] In one possible design, a lifting frame slides through the top frame, two pressure plates are fixedly connected to the bottom of the lifting frame, a cylinder is fixedly installed on the top of the top frame, and the top end of the cylinder's output shaft is fixedly connected to the bottom of the lifting frame.

[0013] In this application, the sheet material is placed on multiple conveyor rollers, each with a support wheel connected to both ends. The support wheels receive and convey the sheet material. A second drive motor is activated, and its output shaft drives a cylindrical pin to rotate. The cylindrical pin engages with a grooved wheel, thus intermittently rotating the conveyor rollers connected to the two support wheels. Support wheels located at the same end of the multiple conveyor rollers are connected to sprockets via chains. Adjacent sprockets are sequentially connected via chain drive, thus intermittently conveying the sheet material. As the sheet material moves, a first drive motor on one side of the U-shaped frame is activated, and its output shaft... The shaft drives the reciprocating lead screw to rotate. The reciprocating lead screw engages with the connecting frame on the outer wall of the reciprocating lead screw via a groove on its outer wall. The connecting frame, through a slider inside the groove, moves the connecting frame back and forth on the reciprocating lead screw. During this movement, the connecting frame causes the sliding frame to slide at the bottom of the U-shaped frame. The sliding frame drives the sliding block, which in turn drives the connecting column. The moving wheel at the bottom of the connecting column rolls on the surface of the sheet metal. A proximity sensor monitors the distance between the top of the connecting column and the proximity sensor to determine the thickness of the sheet metal. When the moving wheel moves upward or downward while rolling on the sheet metal surface, the distance between the top of the connecting column and the proximity sensor is monitored. The distance between the sensors changes, allowing the thickness of the sheet metal at corresponding locations to be read by proximity sensors. This facilitates subsequent control of the servo motor height for grooving the sheet metal. When the sheet metal moves below the top frame, the lifting frame moves downwards via the retraction of the cylinder output shaft. Two pressure plates at the bottom of the lifting frame press and limit the sheet metal from above on both sides. Depending on the desired grooving position, two third drive motors are activated. These motors drive lead screws to rotate, which in turn drive nuts to slide. The nuts then drive push frames to slide, creating a staggered cross shape between the two push frames. The placement is achieved by moving two push frames, which in turn moves the mounting frame. The mounting frame can be moved to any position on the board and can be cut from either end of the groove via a servo motor, thus achieving bidirectional automatic grooving of the board. Simultaneously, the servo motor's lifting and lowering is achieved by activating a fourth drive motor. The output shaft of the fourth drive motor drives two meshing gears to rotate, one of which drives a lead screw to rotate. The mounting frame is threaded onto the outer wall of the lead screw, thereby driving the mounting frame to lift and lower. The mounting frame drives the servo motor, which can be adjusted to drive the milling cutter to the required grooving height on the board for grooving.

[0014] Beneficial effects: In this utility model, the thickness detection mechanism and bidirectional automatic grooving machine, through the coordinated action of components such as connecting column, spring, moving wheel, and sliding block, the distance sensing of the connecting column by the proximity sensor, and the reciprocating sliding groove cooperation between the reciprocating screw and the connecting frame, can ensure the stability and accuracy of the measurement results, and greatly improve the accuracy of thickness detection. In this utility model, the thickness detection mechanism and bidirectional automatic grooving machine can precisely control the position and movement trajectory of the grooving tool through the drive of the lead screw and the third drive motor in the top frame, as well as the sliding cooperation of the push frame, nut and mounting bracket, to achieve bidirectional grooving operation. This not only improves grooving efficiency, but also reduces manual intervention, operation difficulty and human error. This invention significantly shortens the production cycle and improves production efficiency. At the same time, due to the significant improvement in the accuracy of thickness detection and grooving operations, the quality and consistency of the products are effectively guaranteed, thereby enhancing the market competitiveness of the products.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1: Refer to Figure 1 Know Figure 3A thickness detection mechanism includes a frame 1, a U-shaped frame 2 fixedly installed on the top of the frame 1, a sliding frame 10 slidably connected inside the U-shaped frame 2, a sliding block 14 slidably connected inside the sliding frame 10, a connecting column 11 slidably passing through the sliding block 14, a spring 12 sleeved on the outer wall of the connecting column 11, a movable wheel 13 fixedly connected to the bottom of the connecting column 11, and the top and bottom of the spring 12 fixedly connected to the bottom of the sliding block 14 and the top of the movable wheel 13, respectively. A proximity sensor 29 is fixedly connected to the top inner wall of the sliding frame 10, and the proximity sensor 29 is located above the connecting column 11. The object whose thickness is to be detected is placed under the moving wheel 13, and the surface of the plate comes into contact with the moving wheel 13. Depending on the thickness of the plate surface, the connecting column 11 will slide up and down through the sliding block 14. When it rises, the spring 12 is compressed and the connecting column 11 moves upward and closer to the proximity sensor 29. When it falls, the spring 12 unfolds and the connecting column 11 moves downward and closer to the proximity sensor 29. The proximity sensor 29 detects the change in the position of the connecting column 11, which can then be converted into relevant information about the thickness of the object.

[0019] Reference Figure 3 A reciprocating lead screw 16 is rotatably connected inside the U-shaped frame 2. The reciprocating lead screw 16 passes through the sliding frame 10. A connecting frame 15 is fixedly connected inside the sliding frame 10, and a slider is fixedly connected inside the connecting frame 15. The slider slides in the helical groove on the outer wall of the reciprocating lead screw 16. In use, the first drive motor drives the reciprocating lead screw 16 to rotate. Because the slider in the connecting frame 15 slides in the helical groove on the outer wall of the reciprocating lead screw 16, the sliding frame 10 can reciprocate within the U-shaped frame 2, thereby driving the moving wheel 13 and proximity sensor 29 and other components to reciprocate together, realizing the thickness detection of different positions of the object.

[0020] Reference Figure 2 The frame 1 contains multiple conveying rollers 3, each with a support wheel 6 fixedly connected to both ends. The support wheel 6 is rotatably connected to the frame 1 via a rotating shaft. A grooved wheel 7 is fixedly fitted onto the outer wall of the rotating shaft of one of the support wheels 6 at one end of the conveying roller 3. A second drive motor 9 is fixedly installed on the inner wall of one side of the frame 1, and the rotating shaft of the second drive motor 9 extends through one side of the frame 1. A cylindrical pin 8 is fixedly fitted onto the outer wall of the rotating shaft of the second drive motor 9, and the grooved wheel 7 rotatably engages with the cylindrical pin 8. When the second drive motor 9 is started, it drives the cylindrical pin 8 to rotate. The cylindrical pin 8 engages with the grooved wheel 7, causing the grooved wheel 7 to rotate intermittently, which in turn drives the conveying roller 3 connected to the grooved wheel 7 to rotate intermittently, realizing the intermittent conveying of the object to be inspected, facilitating the thickness inspection mechanism to inspect the object.

[0021] Reference Figure 1Each of the multiple conveying rollers 3 has a double-row sprocket fixedly fitted on the outer wall of the rotating shaft of the support wheel 6 at the other end. Adjacent double-row sprockets are connected by sprocket drive. Through the transmission action of the double-row sprockets and chains, the other conveying rollers 3 can rotate synchronously, ensuring the smooth operation of the object during the conveying process and guaranteeing the accuracy of thickness detection.

[0022] Example 2: Reference Figure 4 and Figure 5 An improvement based on Embodiment 1: A bidirectional automatic grooving machine includes the aforementioned thickness detection mechanism, and also includes a top frame 4 fixedly installed on the top of the frame 1. The top frame 4 has two push frames 20 arranged in a cross-shaped staggered arrangement. One end of each push frame 20 is fixedly connected to a mating block 22, and the other end of each push frame 20 is fixedly connected to a nut 21. Both the push frames 20 and the nuts 21 slide within the top frame 4. Two lead screws 27 are rotatably connected within the top frame 4, and the two lead screws 27 are threaded through the nuts 21 respectively. Two third drive motors 19 are fixedly installed within the top frame 4, and one end of each of the two lead screws 27 is fixedly connected to one end of the rotating shaft of each of the two third drive motors 19. The same mounting bracket 23 is slidably connected within the two push frames 20. The thickness detection mechanism first detects the thickness of the object, and then, based on the detection results, it starts two third drive motors 19, which drive two lead screws to rotate respectively. Since the nut 21 is threadedly connected to the lead screw, the two push frames 20 slide within the top frame 4. Since the two push frames 20 are arranged in a cross-shaped staggered position, they drive the mounting frame 23 to move in two directions to adjust its position for subsequent grooving operations.

[0023] refer to Figure 5 A servo motor 28 is located at the bottom of the mounting bracket 23. A mounting frame 26 is located inside the mounting bracket 23, sliding through to the bottom of the mounting bracket 23. The servo motor 28 is fixedly mounted on the bottom of the mounting frame 26. A lead screw 27 is rotatably connected inside the mounting bracket 23, and the mounting frame 26 is threaded onto the outer wall of the lead screw 27. A fourth drive motor 24 is fixedly connected inside the mounting bracket 23. Gears 25 are fixedly fitted onto the outer wall of the rotating shaft of the fourth drive motor 24 and the top of the mounting frame 26, and the two gears 25 mesh with each other. After the mounting bracket 23 is moved to a suitable position, the fourth drive motor 24 is started. The fourth drive motor 24 drives one of the gears 25 to rotate. Through the meshing of the two gears 25, the lead screw 27 rotates. Because the mounting frame 26 is threaded onto the outer wall of the lead screw 27, the mounting frame 26 slides up and down inside the mounting bracket 23, thereby driving the servo motor 28 to move up and down, adjusting the height of the grooving tool. Then, the servo motor 28 is started to perform the grooving operation.

[0024] refer to Figure 4A lifting frame 5 slides through the top frame 4. Two pressure plates 18 are fixedly connected to the bottom of the lifting frame 5. A cylinder 17 is fixedly installed on the top of the top frame 4, and the top end of the output shaft of the cylinder 17 is fixedly connected to the bottom of the lifting frame 5. When the cylinder 17 is activated, the output shaft of the cylinder 17 extends, pushing the lifting frame 5 downward, which in turn drives the two pressure plates 18 downward, pressing and fixing the object to be grouted onto the conveyor roller 3 to prevent the object from moving during the grooving process and to ensure the quality and accuracy of the grooving.

[0025] However, as is well known to those skilled in the art, the working principles and wiring methods of the second drive motor 9, cylinder 17, third drive motor 19, fourth drive motor 24 and servo motor 28 are commonplace and belong to conventional methods or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0026] In this utility model, the proximity sensor 29 is the same as the proximity sensor of the Zhican E2F series.

The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
