Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of production and processing of lightweight wall panels, and specifically relates to a fixed-length cutting device for production and processing of ALC lightweight wall panels. Background Art
[0002] Lightweight wallboard, referred to as ALC board, is prepared by mixing concrete base material, stirring for 5 to 10 minutes to mix evenly, casting and forming, and then hardening for 2 days, and then putting it into the steam chamber for steam processing. After steam processing, the ALC board is placed on the cutting machine after cooling and cut according to the required size.
[0003] The cutting machine uses a platform to place the ALC board flat, and after calibrating the ALC board, the cutting position is facing the circular saw. The ALC board on the platform is pressed tightly by a pressure plate from above, and the circular saw is restarted, rotating and moving in a straight line to cut the ALC board at the required cutting position.
[0004] When cutting existing ALC boards, a ruler or reserved scale is generally used to directly measure the length of the cut part. Manual measurement is time-consuming and laborious. Using a cylinder to push the baffle to limit the fixed length position will block the lateral unloading space of the cut part, so that the ALC board needs to be manually carried upward after cutting, which is not conducive to the convenience of unloading after fixed-length cutting. For this reason, we propose a fixed-length cutting device for the production and processing of ALC lightweight wall panels. Utility Model Content
[0005] The purpose of the utility model is to provide a fixed-length cutting device for the production and processing of ALC lightweight wall panels, which can quickly find the fixed-length cutting position of the ALC board. After the ALC board is cut, the unloading channel is unobstructed, which can improve the convenience of unloading after fixed-length cutting.
[0006] The technical solutions adopted in this utility are as follows:
[0007] A fixed-length cutting device for the production and processing of ALC lightweight wall panels comprises two conveyor belts, wherein a driving mechanism and a circular saw are sequentially arranged in the middle of the two conveyor belts from bottom to top, wherein the driving mechanism is used to rotate the circular saw, wherein one of the conveyor belts is used for loading, and the other conveyor belt is used for unloading and a displacement mechanism is fixed on the upper surface of the conveyor belt, and a crossbeam connected to the displacement mechanism is arranged above the other conveyor belt, a brake motor is fixed on one side of the crossbeam, and a baffle is fixed on the output end of the brake motor, and the baffle is rotated downward by the brake motor and fits with one side of the crossbeam. When cutting the ALC board, the ALC board is placed flat on the belt of the loading conveyor belt, and the crossbeam reaches a designated position and contacts the circular saw. The cutting surface maintains a specified distance, and the brake motor is controlled to rotate forward so that the baffle is in contact with one side of the beam. At this time, the lower end of the baffle is close to the belt of the unloading conveyor belt, and the ALC board is driven forward by the loading conveyor belt until one end of the ALC board is against the side of the baffle away from the beam. The fixed-length cutting position of the ALC board can be quickly found, and then the ALC board is pressed, and the circular saw is rotated in a straight line by the driving mechanism to cut the ALC board. After cutting, the displacement mechanism drives the beam and the baffle away from the ALC board, and the brake motor rotates in the opposite direction to disengage the baffle from the beam. After the ALC board is cut, the unloading channel is unobstructed, and the cut part of the ALC board is transported by the unloading conveyor belt. The coordination is good, which can improve the convenience of unloading after fixed-length cutting.
[0008] The displacement mechanism includes a screw rod rotatably connected to the upper surface of the conveyor belt, the screw rod thread penetrates the cross beam, and a servo motor is also fixedly installed on the upper surface of the conveyor belt. The output end of the servo motor is axially fixedly connected to one end of the screw rod. When the servo motor rotates the screw rod forward, the screw rod pushes the cross beam axially along the thread to approach the circular saw. Conversely, when the servo motor reverses the screw rod, the screw rod pushes the cross beam axially along the thread to move away from the circular saw, thereby realizing that the cross beam drives the baffle plate to approach or move away from the ALC plate, and limits the fixed length of the ALC plate.
[0009] A guide rod is fixed on the upper surface of the conveyor belt away from the screw rod. The guide rod passes through the crossbeam. The guide rod and the screw rod are parallel to each other. When the crossbeam moves, it slides along the guide rod, so that the screw rod and the guide rod form two fulcrums. The crossbeam can be supported and limited at the same time, so that the crossbeam is always parallel to the cutting surface of the circular saw.
[0010] A sliding tube is fixedly passed through one end of the cross beam, and the sliding tube is sleeved outside the guide rod. The sliding tube increases the contact area between the cross beam and the guide rod, and reduces the occurrence of cracks at the contact position.
[0011] The driving mechanism includes an electric shift rail fixedly connected to both conveyor belts, a rotating motor is slidably mounted on the upper surface of the electric shift rail, an output end of the rotating motor is connected to the middle transmission of the circular saw, starting the rotating motor can rotate the circular saw, starting the electric shift rail can drive the rotating motor and the circular saw forward or backward, so that the circular saw is displaced to a position between the two conveyor belts with a stroke wider than the width of the conveyor belt, so as to cut the ALC board in a straight line.
[0012] A reinforcing ring is fixed through one end of the crossbeam away from the sliding tube. The reinforcing ring is sleeved on the outside of the screw rod. The reinforcing ring increases the thickness of the contact position between the crossbeam and the screw rod, improves the structural strength at the corresponding screw rod fulcrum, and reduces the occurrence of cracks at the contact position.
[0013] The technical effects achieved by this utility model are:
[0014] The present invention discloses a fixed-length cutting device for producing and processing ALC light wall panels. When cutting the ALC board, the ALC board is placed flat on the belt of the loading conveyor belt. The crossbeam reaches the specified position and keeps a specified distance from the cutting surface of the circular saw. The brake motor is controlled to rotate the baffle in the forward direction to fit with one side of the crossbeam. At this time, the lower end of the baffle is close to the belt of the unloading conveyor belt, and the ALC board is driven forward by the loading conveyor belt until one end of the ALC board is against the side of the baffle away from the crossbeam. The fixed-length cutting position of the ALC board can be quickly found, and then the ALC board is pressed, and the circular saw is rotated by the driving mechanism to move in a straight line to cut the ALC board. After cutting, the displacement mechanism drives the crossbeam and the baffle away from the ALC board, and the brake motor rotates in the reverse direction to disengage the baffle from the crossbeam. After the ALC board is cut, the unloading channel is unblocked, and the cut part of the ALC board is transported by the unloading conveyor belt. The coordination is good, and the convenience of unloading after fixed-length cutting can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.
[0023] like Figure 1-5 As shown, a fixed-length cutting device for the production and processing of ALC lightweight wall panels includes two conveyor belts 1 and an industrial control host. The industrial control host can be a Micro-ATX series industrial computer, supporting 2 RS232 / 422 / 485 and 8 RS232 serial ports. The industrial control host signal is connected to the two conveyor belts 1. A driving mechanism and a circular saw 2 are arranged in sequence from bottom to top in the middle of the two conveyor belts 1. The driving mechanism is used to rotate the circular saw 2. One of the conveyor belts 1 is used for loading. A cylinder and a pressing plate are fixed on the top of the conveyor belt 1 from top to bottom. This technology The scheme is the existing technology, which is not shown in the figure. The cylinder signal is connected to the industrial control host. The cylinder is fixedly connected to the frame of the conveyor belt 1 through a steel frame. Another conveyor belt 1 is used for unloading and a displacement mechanism is fixed on the upper surface of the conveyor belt 1. A beam 3 connected to the displacement mechanism is arranged above the other conveyor belt 1. A brake motor 4 is fixed on one side of the beam 3. The brake motor 4 can choose a YEJ series three-phase asynchronous motor. A baffle 5 is fixed on the output end of the brake motor 4. The baffle 5 is rotated downward by the brake motor 4 and fits with one side of the beam 3. The concrete mixture is cast and formed through steam processing to form a ALC board, when cutting the ALC board, start the two conveyor belts 1 to rotate synchronously, place the ALC board flat on the belt of the feeding conveyor belt 1, and start the displacement mechanism to push the beam 3 to the specified position of the unloading conveyor belt 1, keep a specified distance from the cutting surface of the circular saw 2, control the brake motor 4 to rotate the baffle 5 in the forward direction to fit one side of the beam 3, at this time, the lower end of the baffle 5 is close to the belt of the unloading conveyor belt 1, and the ALC board is driven forward by the feeding conveyor belt 1 until one end of the ALC board is against the side of the baffle 5 away from the beam 3, so that the side of the baffle 5 away from the beam 3 and the cutting surface of the circular saw 2 are The spacing is the cutting length of the ALC board, which can quickly find the fixed-length cutting position of the ALC board, and then start the cylinder to push the pressure plate downward to press the ALC board. The driving mechanism rotates the circular saw 2 and drives the circular saw 2 to move in a straight line between the two conveyor belts 1 to cut the ALC board. After cutting, the displacement mechanism drives the beam 3 and the baffle 5 away from the ALC board, and the brake motor 4 rotates the baffle 5 in the opposite direction to disengage the beam 3. After the ALC board is cut, the unloading channel is unobstructed, and the unloading conveyor belt 1 is used to transport the cut part of the ALC board. The coordination is good, which can improve the convenience of unloading after fixed-length cutting.
[0024] The industrial control host signal is connected to the driving mechanism, brake motor 4 and displacement mechanism, and can be controlled by a preset program so that after one-key start, the ALC board is automatically loaded, pressed, cut and unloaded. After unloading, the cylinder is controlled to lift the pressure plate and release the remaining part of the ALC board.
[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the displacement mechanism includes a screw rod 6 rotatably connected to the upper surface of the conveyor belt 1. The outside of the screw rod 6 is rotatably connected to the upper surface of the conveyor belt 1 through a bearing. The screw rod 6 threads through the crossbeam 3. A servo motor 7 is also fixedly installed on the upper surface of the conveyor belt 1. The signal of the servo motor 7 is connected to the industrial control host. The servo motor 7 can use a YEJ series three-phase asynchronous motor. The output end of the servo motor 7 is axially fixedly connected to one end of the screw rod 6. The servo motor 7 rotates the screw rod 6 forward, and the screw rod 6 pushes the crossbeam 3 axially along the thread to approach the circular saw 2. Conversely, the servo motor 7 reverses the screw rod 6, and the screw rod 6 pushes the crossbeam 3 axially away from the circular saw 2 along the thread, so that the crossbeam 3 drives the baffle 5 to approach or move away from the ALC board, and the ALC board is limited in fixed length.
[0026] like Figure 1 and Figure 3 As shown, a guide rod 8 is fixed on the upper surface of the conveyor belt 1 away from the screw rod 6. The guide rod 8 passes through the crossbeam 3. The guide rod 8 and the screw rod 6 are parallel to each other. When the crossbeam 3 moves, it slides along the guide rod 8, so that the screw rod 6 and the guide rod 8 form two fulcrums, which can support the crossbeam 3 and limit it at the same time, so that the crossbeam 3 is always parallel to the cutting surface of the circular saw 2.
[0027] like Figure 1 and Figure 3 As shown, a sliding tube 9 is fixedly passed through one end of the cross beam 3, and the sliding tube 9 is sleeved on the outside of the guide rod 8. The sliding tube 9 increases the contact area between the cross beam 3 and the guide rod 8, and reduces the occurrence of cracks at the contact position.
[0028] like Figure 1 , Figure 2 and Figure 5 As shown, the driving mechanism includes an electric rail shift 10 fixedly connected to the two conveyor belts 1. The electric rail shift 10 can use a HIWINCG torque-resistant ball guide rail. A rotating motor 11 is slidably installed on the upper surface of the electric rail shift 10. The signal of the rotating motor 11 is connected to the industrial control host. The rotating motor 11 can use a YEJ series three-phase asynchronous motor. The output end of the rotating motor 11 is connected to the intermediate transmission of the circular saw 2. Starting the rotating motor 11 can rotate the circular saw 2. Starting the electric rail shift 10 can drive the rotating motor 11 and the circular saw 2 to move forward or backward, so that the circular saw 2 is displaced in the middle of the two conveyor belts 1 with a stroke wider than the width of the conveyor belt 1, so as to cut the ALC board in a straight line.
[0029] like Figure 1 and Figure 3As shown, a reinforcing ring 12 is fixed through one end of the cross beam 3 away from the sliding tube 9. The reinforcing ring 12 is sleeved on the outside of the screw rod 6. The reinforcing ring 12 increases the thickness of the contact position between the cross beam 3 and the screw rod 6, improves the structural strength at the corresponding fulcrum of the screw rod 6, and reduces the occurrence of cracks at the contact position.
[0030] The working principle of the utility model is: when cutting the ALC board, the two conveyor belts 1 are started to rotate synchronously, the ALC board is placed flat on the belt of the feeding conveyor belt 1, and the displacement mechanism is started to push the beam 3 to the specified position of the unloading conveyor belt 1, and keep a specified distance from the cutting surface of the circular saw 2, and the brake motor 4 is controlled to rotate the baffle 5 in the forward direction to fit with one side of the beam 3. At this time, the lower end of the baffle 5 is close to the belt of the unloading conveyor belt 1, and the ALC board is driven forward by the feeding conveyor belt 1 until one end of the ALC board is against the side of the baffle 5 away from the beam 3, so that the distance between the side of the baffle 5 away from the beam 3 and the cutting surface of the circular saw 2 is the cutting length of the ALC board, and the fixed-length cutting position of the ALC board can be quickly found.
[0031] Then start the cylinder to push the pressure plate downward to press the ALC board, use the driving mechanism to rotate the circular saw 2 and drive the circular saw 2 to move in a straight line between the two conveyor belts 1 to cut the ALC board. After cutting, the displacement mechanism drives the beam 3 and the baffle 5 away from the ALC board, and the brake motor 4 rotates the baffle 5 in the opposite direction to disengage the beam 3. After the ALC board is cut, the unloading channel is unobstructed, and the unloading conveyor belt 1 is used to transport the cut part of the ALC board, which has good coordination and can improve the convenience of unloading after fixed-length cutting.
