Description

Technical Field

[0001] This utility model relates to the field of building material cutting technology, and in particular to a cutting device for processing building materials. Background Technology

[0002] Cutting is an essential step in the processing of building materials (such as gypsum board and cement fiberboard). After cutting, the materials need to be smoothly and neatly transferred from the processing position to a designated location (such as the next process or stacking area). This process is called unloading. Common unloading methods include: Manual handling: Inefficient, labor-intensive, poses safety hazards for large materials, and it's difficult to ensure neatness during manual placement. Simple pusher / baffle: Materials are pushed off the production line using a cylinder or manually pushed baffle. This method often suffers from limited pusher stroke, low alignment accuracy, easy jamming, inability to control the falling posture of materials, easy damage to materials, and difficulty in automatically stacking neatly.

[0024] Example 1

[0025] A blanking device for processing building panels, such as Figure 1 and 3 As shown, the device includes a base frame 1, on which a conveying mechanism is provided. The conveying mechanism includes a first conveyor belt 2 mounted on the base frame 1. A feeding mechanism is provided on one side of the base frame 1 in the conveying direction. The feeding mechanism includes a side plate 3. Two rows of retractable guide columns are provided on one side of the side plate 3, namely a left guide column 401 and a right guide column 402. Each row of guide columns is staggered and the distance between each row of guide columns is equal in the vertical direction. A retractable receiving column 5 is provided between the two rows of guide columns and is flush with the top left guide column. One end of the guide column and the receiving column are fixedly connected to the piston rod of the telescopic cylinder to realize the telescopic function. The surface of the guide column is covered with a polyurethane buffer layer.

[0026] A limiting plate 6 is symmetrically provided on the outer side of the guide column. Each limiting plate 6 is laterally equidistant from its nearest guide column. A transfer mechanism is provided below the side plate 3. The transfer mechanism includes a second conveyor belt 7 located below the side plate. The conveying directions of the first conveyor belt 2 and the second conveyor belt 7 are perpendicular to each other. Push plates 8 that can move in opposite directions are symmetrically provided on both sides along the conveying direction of the second conveyor belt 7 to further align all the plates.

[0027] Both the left guide post and the receiving post at the top are roller structures. When the leftmost end of the plate leaves the conveyor belt, it can still move a certain distance on the left guide post and the receiving post due to inertia. A limit switch is provided on the side plate (located on the movement path of the plate). When the plate 9 moves on the first conveyor belt 2 and passes the left guide post and the receiving post at the top in sequence, it will trigger the limit switch when it continues to move to the right (at this time, the plate 9 completely leaves the first conveyor belt 2). The limit switch is linked with the telescopic cylinder corresponding to the receiving post. The working process is as follows: When no object triggers the limit switch, the normally open contact of the limit switch opens, the relay and the solenoid valve are de-energized, compressed air enters the rodless chamber of the cylinder, pushing the piston rod to extend. When the object moves and contacts the actuator plate, it pushes the actuator plate to touch the limit switch roller, the normally open contact inside the limit switch closes, the relay coil is energized, the normally open contact of the relay closes, the solenoid valve coil is energized, the solenoid valve core reverses, the compressed air enters the rod chamber of the cylinder, the gas exhaust port of the rodless chamber is discharged, and the piston rod retracts. When the plate moves away, the actuator plate loses its thrust, the limit switch roller resets under the action of the internal spring, the normally open contact opens, the relay coil is de-energized, the relay contact opens, and the solenoid valve coil is de-energized; the solenoid valve core resets, compressed air re-enters the rodless chamber, the piston rod extends, and the actuator plate returns to its initial position, waiting for the next trigger.

[0028] It also includes a controller, with an infrared distance sensor at the top of the side panel. The output of the infrared distance sensor is electrically connected to the input of the controller, and the output of the controller is connected to the telescopic cylinder of the guide column.

[0029] Multiple sets of infrared sensors can be deployed, each corresponding to a different distance range. Alternatively, high-precision infrared sensors (such as laser rangefinders) can be used, with multiple distance thresholds programmed to replace multiple sets of sensors. A multi-channel controller (such as a PLC expansion module) supports simultaneously receiving signals from multiple sensors or processing multiple threshold outputs from a single sensor. It has multi-port control capabilities, with each cylinder corresponding to an independent solenoid valve, controlled individually by different ports of the controller. Application scenario: As the sheet material accumulates and its thickness gradually increases, multiple guide pillars above it will have an impact. As the distance detected by the infrared sensors from the sheet material decreases, the sensing range is divided into multiple intervals. Each interval corresponds to a specific cylinder action, gradually retracting the guide pillars from bottom to top.

[0030] The telescopic cylinder and other structures are existing technologies and will not be described in detail here. In addition, this utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail here.

[0031] Working and usage process:

[0032] This utility model is used for sheet materials that are not easily damaged by impacts and is suitable for sheet materials of fixed size. To better understand the entire working process, the guide columns are first numbered. The left guide columns are numbered from top to bottom as Left 1, Left 2, Left 3...Left n, and the right guide columns are numbered from top to bottom as Right 1, Right 2, Right 3...Right n, as follows. Figure 2 As shown, firstly, the cut sheet material gradually moves towards the side plate on the first conveyor belt. The front end of the sheet material passes through Left 1, the receiving column, and the limit switch in sequence. After the limit switch is triggered, the receiving column retracts, the middle of the sheet material loses support, and its right end tilts towards Right 1 and gradually slides downward to the right. After the sheet material is received by Right 1 and its right end touches the limit plate, the left end leaves the support of Left 1 and tilts towards Left 2, gradually sliding downward to the left. After the sheet material is received by Left 2 and its left end touches the limit plate, the right end leaves the support of Right 1 and tilts towards Right 2, gradually sliding downward to the right. After the sheet material is received by Right 2 and its right end touches the limit plate, the left end leaves the support of Left 2 and tilts towards Left 3, gradually sliding downward to the left, and so on, until the sheet material falls onto the bottom transfer mechanism. Figure 2 The last figure shows a schematic diagram of the plate about to fall onto the transfer mechanism. Then the second and third plates are stacked together. As the thickness of the plates increases, the guide columns gradually retract from bottom to top.

[0033] The stacked boards are taken away by the transfer mechanism. When they pass the pusher, the second conveyor belt stops and the pusher moves in opposite directions to further align all the boards. The pusher has a connecting rod on its back, which is connected to an existing drive device, such as a cylinder.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
