Description

Technical Field

[0001] This utility model relates to the field of building material processing technology, specifically to a composite polystyrene board cutting machine. Background Technology

[0002] In the processing of composite polystyrene boards, the positioning accuracy of the boards on the transport platform is a key factor determining the final cutting dimensional accuracy. Existing equipment is often equipped with simple limit baffles, which have limited correction capabilities. When the boards are significantly offset or skewed due to improper placement or slippage during transport, simple calibration mechanisms are insufficient to restore them to the precise preset position, resulting in out-of-tolerance dimensions of the cut workpieces and material waste. This is especially critical when processing precision assembled components or irregularly shaped parts, where the positioning accuracy requirements for the substrate are particularly stringent. Summary of the Invention

[0003] The present invention aims to provide a composite polystyrene board cutting machine with high efficiency and high precision positioning.

[0004] To achieve the above objectives, this utility model provides a composite polystyrene board cutting machine, comprising: a frame; a conveyor belt disposed within the frame, the conveyor belt including multiple conveyor shafts arranged side by side; a cutting system disposed at the end of the frame away from the feeding direction, located above the conveyor belt; a preliminary guiding mechanism fixedly disposed on the frame, located at the inlet end of the conveyor belt; a sensing and detection unit disposed at the rear station of the preliminary guiding mechanism; a correction mechanism disposed between the cutting system and the sensing and detection unit, the correction mechanism having a general position and a restricted position; and an electrical control system electrically connected to the sensing and detection unit and the correction mechanism, the electrical control system controlling the correction mechanism to move between the general position and the restricted position by receiving electrical signals from the sensing and detection unit.

[0005] Furthermore, the preliminary guiding structure includes two guide plates, forming an "eight"-shaped channel between them. The larger end of the channel forms the channel inlet, facing the feed end of the conveyor belt, while the smaller end forms the channel outlet, facing the cutting system.

[0006] Furthermore, the sensing and detection unit includes at least two sets of through-beam photoelectric sensor groups arranged at intervals along the feeding direction. Each sensor group contains two sensors, which are arranged opposite each other on both sides of the conveyor belt.

[0007] Furthermore, the correction mechanism includes two parallel ball screws, each of which is driven by an independent servo motor. The direction of movement of the ball screws is perpendicular to the transport direction of the conveyor belt in the horizontal plane. Each ball screw is equipped with a baffle. The servo motors are electrically connected to the electrical control system, which can control the movement of the two servo motors separately.

[0008] Furthermore, the inner surface of the baffle is provided with an engineering plastic with a low coefficient of friction.

[0009] In the technical solution of this utility model, the feeding direction of the composite polystyrene board is guided by the preliminary guiding mechanism, and then the deviation position of the composite polystyrene board is detected by the sensing and detection unit and the position information is converted into an electrical signal and transmitted to the electrical control system. The electrical control system controls the correction mechanism to restrict the composite polystyrene board to the correct cutting position according to the received electrical signal, which greatly improves the positioning accuracy during processing. Attached Figure Description

[0010] Figure 1 A partial structural schematic diagram of Embodiment 1 of the composite polystyrene board cutting machine of this utility model is shown. Detailed Implementation

[0011] See also Figure 1 As shown in the figure, the composite polystyrene board cutting machine of Embodiment 1 includes: a frame 10; a conveyor belt 20 disposed within the frame of the frame 10, the conveyor belt 20 including multiple conveyor shafts arranged side by side; a cutting system 30 disposed at the end of the frame 10 away from the feeding direction, located above the conveyor belt 20; a preliminary guiding mechanism 40 fixedly disposed on the frame 10, located at the inlet end of the conveyor belt 20; a sensing and detection unit 50 disposed at the rear station of the preliminary guiding mechanism 40; a correction mechanism disposed between the cutting system 30 and the sensing and detection unit 50, the correction mechanism having a normal position and a restricted position; and an electrical control system electrically connected to the sensing and detection unit 50 and the correction mechanism, the electrical control system controlling the correction mechanism to move between the normal position and the restricted position by receiving electrical signals from the sensing and detection unit 50.

[0012] The composite polystyrene board cutting machine of this embodiment guides the feeding direction of the composite polystyrene board through the preliminary guiding mechanism 40, and then detects the deviation position of the composite polystyrene board through the sensing and detection unit 50 and converts the position information into an electrical signal and transmits it to the electrical control system. The electrical control system controls the correction mechanism to move to the limit position according to the received electrical signal, thereby limiting the composite polystyrene board to the correct cutting position, which greatly improves the positioning accuracy during processing.

[0013] In a preferred embodiment, the preliminary guiding mechanism 40 includes two guide plates fixedly mounted on the frame 10, forming a figure-eight channel. The larger end of the channel forms the inlet, facing the feed end of the conveyor belt 20, and the smaller end forms the outlet, facing the cutting system 30. When the composite polystyrene board is placed on the conveyor belt 20 for transport, the channel shape, from large to small, allows the initial placement position of the composite polystyrene board on the conveyor belt to be disregarded. After transport by the conveyor belt and the limiting action of the guide plates, the axis of the composite polystyrene board after passing the guide plates is ensured to be parallel to the transport axis of the conveyor belt, thus restoring the composite polystyrene board to the correct feeding direction.

[0014] A sensing and detection unit 50 is installed at the rear station of the initial guiding mechanism 40. The sensing and detection unit 50 has at least two sets of through-beam photoelectric sensor groups spaced apart along the feeding direction. Each sensor group contains two sensors, which are positioned opposite each other on both sides of the conveyor belt 20, forming a detection point. As the conveyor belt 20 moves, the composite polystyrene board will reach the detection range of the sensing and detection unit 50 after the initial limit position and pass through the detection point. The current position of the composite polystyrene board is detected through at least two monitoring points. By comparing the detected signal with a predetermined signal, the deviation value of the current composite polystyrene board relative to the predetermined processing position can be calculated. In this embodiment, the photoelectric sensor can be a photoelectric sensor of model HG-400-A from the brand "Photonics".

[0015] Following the sensing and detection unit 50 is a web-correcting mechanism, which includes two parallel ball screws 61. The movement direction of the ball screws 61 is perpendicular to the transport direction of the conveyor belt 20 in the horizontal direction. Each ball screw is equipped with a baffle 62 and a servo motor. Both servo motors are electrically connected to the electronic control system, which can control the movement of the two servo motors independently. The baffle 62, driven by the motors of the ball screws 61, can reciprocate in the horizontal direction perpendicular to the feeding direction. The baffle 62 has a general position located outside the conveyor belt and a limiting position located inside the conveyor belt, which restricts the composite polystyrene board to a predetermined processing position. The electronic control system is electrically connected to both the servo motor and the sensing unit 50. The system records the position of the ball screw and receives the deviation signal transmitted from the sensing unit 50. By calculating the current position and deviation signal of the ball screw 61, the system determines the movement distance of the ball screw 61 and controls the output of the servo motor. This causes both ball screws 61 to move simultaneously, moving the baffle 62 from its normal or current position to a restricted position, thereby changing the position of the composite polystyrene board to the predetermined processing position. When the sensing unit 50 detects that no composite polystyrene board is currently passing, the electronic control system controls the motor to return the baffle 62 to its normal position. To reduce friction between the baffle 62 and the composite polystyrene board, a low-friction coefficient engineering plastic can be used on the inner surface of the baffle 62 that contacts the composite polystyrene board. This reduces the contact resistance, allowing the baffle 62 to better guide the composite polystyrene board to the predetermined processing position and reducing frictional wear on the composite polystyrene board.

[0016] In another preferred embodiment, the two baffles 62 may move as follows: one baffle 62 is first positioned parallel to the material conveying direction and located on a boundary of the predetermined processing position to act as a limit; then the other baffle 62 moves toward the composite polystyrene board on the other side until the two baffles 62 are respectively in the restricted position to ensure that the composite polystyrene board between the two baffles is in the predetermined processing position.

[0017] In this embodiment, the photoelectric sensor can be selected as the HG-400-A model photoelectric sensor from the brand Photonics.
