Description

Technical Field

[0001] This utility model relates to the field of sheet material conveying technology, and in particular to a push-type sheet material cutting mechanism. Background Technology

[0002] The existing patent publication number CN218227008U discloses a double-head saw for cutting wood panels, including a machine base and a drive platform. An adjustment chamber is fixedly installed on the machine base, and a screw is movably installed on the inner wall of the adjustment chamber. A support base is fixedly installed on the bottom inner wall of the adjustment chamber, while a T-shaped seat is fixedly installed on the top. A fixed seat is slidably connected to the inner wall of the T-shaped seat. In this application, when the fixed seat is manually pulled, it pulls the connecting rod upwards via a pull rod, stretching the spring. Under the action of the connecting rod, the limiting ring causes the elastic pad to press tightly against the outer wall of the open end of the screw. After the moving plug rod engages with the slot and is mounted on top of the T-shaped seat, the fixed seat is released. At this point, the fixed seat and pull rod remain stable, while the limiting ring is fixed to the outer wall of the open end of the screw, providing axial constraint to limit the self-deflection of the screw caused by vibration, thereby ensuring the stability of the drive platform and improving the stability of the double-head saw.

[0003] However, this device has the following drawbacks during use: It requires manual pushing during material feeding, which can easily cause the material to shift, leading to cutting errors. Furthermore, the close proximity of the cutting disc to the operator during manual pushing increases the risk of injury. To address these drawbacks, we propose a push-type material cutting mechanism. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a push-type sheet metal cutting mechanism.

[0005] To address the problems existing in the prior art, this utility model adopts the following technical solution: a push-type sheet metal cutting mechanism, comprising:

[0006] The conveyor frame includes a support frame, a first drive shaft and a second drive shaft rotatably mounted on the inner wall of the support frame, two drive sprockets and two driven sprockets symmetrically fixedly mounted on the surfaces of the first drive shaft and the second drive shaft, a chain that is connected to the drive sprockets and driven sprockets, a plurality of push blocks that are fixedly mounted at equal intervals on the surface of the chain, and a first motor fixedly mounted on the front of the support frame for driving the first drive shaft to rotate.

[0007] The cutting mechanism includes a gantry frame, a guide column fixedly installed on the inner wall of the gantry frame, a bidirectional lead screw rotatably installed on the inner wall of the gantry frame, two nut seats that are helically driven by the bidirectional lead screw, a cutting component set below the nut seats, and a second motor fixedly installed on the front of the gantry frame. The surface of the bidirectional lead screw is provided with two sections of threads with opposite rotation directions.

[0008] A plate positioning mechanism is provided on the front of the support frame and is used to position the plate.

[0009] A sheet metal auxiliary conveying mechanism is installed inside the gantry frame and is used for auxiliary conveying of sheet metal.

[0010] Preferably, the cutting component includes a mounting plate fixedly mounted on the lower ends of two nut seats, a cutting disc rotatably mounted on the surface of the mounting plate, and a third motor fixedly mounted on the surface of the mounting plate for driving the cutting disc to rotate.

[0011] Preferably, the sheet metal auxiliary conveying mechanism includes a mounting base fixedly mounted on the surface of the guide column, a cylinder fixedly mounted on the lower end of the mounting base, a roller seat fixedly mounted on the lower end of the cylinder, and a conveying roller rotatably mounted on the inner wall of the roller seat.

[0012] Preferably, the surface of the nut seat is provided with a guide hole, and the nut seat slides with the guide post through the guide hole.

[0013] Preferably, the plate positioning mechanism includes an L-shaped connecting plate fixedly installed on the front of the support frame, an adjusting bolt threadedly connected to the surface of the L-shaped connecting plate, and a positioning plate rotatably installed on the threaded end of the adjusting bolt.

[0014] Preferably, the inner bottom wall of the L-shaped connecting plate is provided with a track groove, and the positioning plate slides in conjunction with the track groove.

[0015] Preferably, the surfaces of the L-shaped connecting plate and the guide post are provided with scale markings.

[0016] Preferably, both ends of the support frame extend through the interior of the gantry frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. The support frame uses a first motor to drive a closed-loop pusher block, enabling continuous directional conveying of the sheet metal. After the sheet metal is conveyed to the cutting head, it can be cut. The cylinder-driven conveying rollers can dynamically adjust their height to adapt to sheet metal of different thicknesses. At the same time, rolling friction suppresses cutting vibration and improves the cross-sectional quality. The conveying, positioning, and cutting modules form a continuous processing flow, reducing manual intervention. On the one hand, it can avoid sheet metal deviation, and on the other hand, it can avoid excessive contact between the operator and the cutting head, thus improving cutting quality and safety.

[0019] 2. The transmission system consisting of a two-way lead screw and a guide column controls the two cutting discs to move synchronously in opposite or the same direction through a second motor, thereby adjusting the cutting width. The guide hole and sliding fit structure eliminate motion deviation and ensure the straightness of the cut.

[0020] 3. By rotating the adjusting bolt, the positioning plate is driven to move horizontally along the track groove of the L-shaped connecting plate. The scale marks are used to accurately calibrate the front and rear positioning positions of the plate. When the plate is placed on the support frame, the front end of the plate contacts the positioning plate to achieve rapid positioning of the plate and prevent the plate from shifting after placement.

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Please see Figures 1-4 This utility model provides a technical solution: a push-type board cutting mechanism, including: a conveyor frame, a cutting mechanism, a board positioning mechanism, and a board auxiliary conveying mechanism.

[0029] The conveyor frame includes a support frame 10, a first drive shaft and a second drive shaft rotatably mounted on the inner wall of the support frame 10, two drive sprockets 11 and two driven sprockets 12 symmetrically fixed on the surfaces of the first drive shaft and the second drive shaft, a chain 13 that is connected to the drive sprockets 11 and the driven sprockets 12, a plurality of push blocks 14 that are equidistantly fixed on the surface of the chain 13, and a first motor 15 fixed on the front of the support frame 10 for driving the first drive shaft to rotate.

[0030] The first motor 15 drives the first drive shaft to rotate, which in turn drives the drive sprocket 11 fixed on it to rotate. The drive sprocket 11 meshes with the driven sprocket 12 through the chain 13 to form a closed-loop transmission system, causing the second drive shaft to rotate synchronously. The push block 14 fixed on the chain 13 moves with the chain 13. When the plate is placed on the support frame 10, the moving push block 14 will push the plate to move directionally along the upper surface of the support frame 10. The linear speed of the chain 13 can be controlled by adjusting the speed of the first motor 15, thereby adjusting the plate conveying efficiency.

[0031] The cutting mechanism includes a gantry frame 20, a guide column 21 fixedly mounted on the inner wall of the gantry frame 20, a bidirectional lead screw 22 rotatably mounted on the inner wall of the gantry frame 20, two nut seats 23 that are helically driven by the bidirectional lead screw 22, a cutting component located below the nut seats 23, and a second motor 24 fixedly mounted on the front of the gantry frame 20 to drive the bidirectional lead screw 22 to rotate. The surface of the bidirectional lead screw 22 is provided with two sections of threads with opposite rotation directions. The surface of the nut seats 23 is provided with guide holes, and the nut seats 23 slide with the guide column 21 through the guide holes. The two ends of the support frame 10 penetrate the interior of the gantry frame 20. The second motor 24 drives the bidirectional lead screw 22 to rotate. Since the surface of the bidirectional lead screw 22 is designed with two sections of threads with opposite rotation directions, when rotating, it can drive the two nut seats 23 to move relative to each other along the guide column 21. The nut seats 23 slide with the guide column 21 through the guide holes on their surfaces to ensure stable movement without rotational deviation, thereby achieving precise adjustment of the position of the cutting component.

[0032] The cutting component includes mounting plates 30 fixedly installed at the lower ends of two nut seats 23, a cutting disc 31 rotatably mounted on the surface of the mounting plates 30, and a third motor 32 fixedly mounted on the surface of the mounting plates 30 to drive the cutting disc 31 to rotate. The movement of the nut seats 23 is linked to the synchronous movement of the cutting component. The third motor 32 of the cutting component drives the cutting disc 31 to rotate at high speed, generating cutting force to cut both ends of the board. The board is transported to the inside of the gantry frame 20 through the support frame 10. The second motor 24 and the third motor 32 work together, and the bidirectional lead screw 22 drives and controls the distance between the two mounting plates 30, thereby controlling the cutting width. The rotating cutting disc 31 performs the cutting task, realizing efficient board cutting.

[0033] The auxiliary conveying mechanism for sheet metal is located inside the gantry 20 and is used to assist in conveying the sheet metal. The auxiliary conveying mechanism includes a mounting base 40 fixedly installed on the surface of the guide column 21, a cylinder 41 fixedly installed at the lower end of the mounting base 40, a roller seat 42 fixedly installed at the lower end of the cylinder 41, and a conveying roller 43 rotatably installed on the inner wall of the roller seat 42. The cylinder 41 drives the roller seat 42 and the conveying roller 43 to rise and fall vertically through telescopic movement, so as to realize the adaptive height adjustment for sheet metal of different thicknesses. The conveying roller 43 rotates freely in the roller seat 42. When the sheet metal passes through, the conveying roller 43 contacts the upper surface of the sheet metal to generate rolling friction, thereby avoiding excessive vertical jumping of the sheet metal when the cutting disc 31 cuts the sheet metal.

[0034] The plate positioning mechanism is located on the front of the support frame 10 and is used to position the plate. The plate positioning mechanism includes an L-shaped connecting plate 50 fixedly installed on the front of the support frame 10, an adjusting bolt 51 threadedly connected to the surface of the L-shaped connecting plate 50, and a positioning plate 52 rotatably installed on the threaded end of the adjusting bolt 51. The inner bottom wall of the L-shaped connecting plate 50 has a track groove, and the positioning plate 52 slides in the track groove. The surfaces of the L-shaped connecting plate 50 and the guide post 21 are both marked with scale marks. By rotating the adjusting bolt 51, the positioning plate 52 is driven to move horizontally along the track groove of the L-shaped connecting plate 50. The scale marks are used to accurately calibrate the front and rear positioning positions of the plate. When the plate is placed on the support frame 10, the front end of the plate contacts the positioning plate 52 to achieve rapid positioning of the plate and prevent the plate from shifting after placement.

[0035] The device forms a continuous processing flow through conveying, positioning, and cutting modules, reducing manual intervention. On the one hand, it can avoid material deviation, and on the other hand, it can prevent operators from having excessive contact with the cutting disc 31, thus improving cutting quality and safety.

[0036] Specifically, the working principle and operation method of this utility model are as follows:

[0037] The positioning plate 52 is driven to slide horizontally along the track groove of the L-shaped connecting plate 50 by rotating the adjusting bolt 51. The front and rear positioning positions of the plate are precisely calibrated using scale markings to ensure that the front end of the plate contacts the positioning plate 52 each time the plate is placed. Then, the second motor 24 is started to drive the bidirectional lead screw 22 to rotate. The two nut seats 23 slide relative to each other along the guide column 21 using the reverse thread section. The spacing of the mounting plates 30 is adjusted synchronously to control the width of the plate after cutting. The operator places the plate on the upper surface of the support frame 10 and starts the first motor 15 to drive the first drive shaft to rotate. The chain 13 runs in a closed loop through the drive sprocket 11 and the driven sprocket 12. The pusher block 14 pushes the plate to move in a direction to the inside of the gantry 20. When the plate enters the cutting area, the cylinder 41 extends and retracts to adjust the height of the conveying roller 43 to match the plate thickness. The roller contacts the upper surface of the plate to form rolling friction, suppressing cutting vibration and preventing the plate from jumping and deviating. At the same time, the third motor 32 is activated to drive the cutting disc 31 to rotate at high speed to cut the two ends of the plate. After cutting, the chain 13 continues to push the plate out of the gantry 20.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
