Description

Technical Field

[0001] This invention relates to the field of mineral wool board technology, and more particularly to a board-mounting machine and method suitable for mineral wool sound-absorbing boards. Background Technology

[0002] In the production of mineral wool boards, the loading process is the first and crucial step. Due to the large size of the mineral wool sound-absorbing boards, it's difficult to ensure consistent pushing force and uniform pressure during the pushing process, making it easy for the boards to be pushed askew. Impact after being pushed askew can cause dents, cracks, and other damage to the board surface. The surface of mineral wool sound-absorbing boards is usually quite fragile, and the impact force can damage its internal structure, exposing the mineral wool fibers, which not only affects aesthetics but also reduces its sound absorption performance. For mineral wool sound-absorbing boards with a decorative coating, impact can cause the coating to peel off, causing the board to lose its original decorative effect. Furthermore, once the coating is peeled off, the board is more susceptible to environmental damage, such as moisture and mold. Summary of the Invention

DETAILED DESCRIPTION

[0038] The technical solutions of the present application will be described clearly and completely below in combination with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0039] As described in the background, the mineral wool sound absorption board is prone to be pushed and skewed during the upper plate process, resulting in impact damage due to force deviation or asynchronization, affecting the product performance and surface decoration effect. Therefore, how to avoid the damage of the mineral wool sound absorption board caused by the pushing and skewing of the mineral wool sound absorption board has become a technical problem to be solved by those skilled in the art.

[0040] To solve the above problems, with reference to Figure 1 , Figure 2 and Figure 3 , the present application provides a plate upper machine suitable for mineral wool sound absorption board, comprising: an elevator 1, a conveying rubber roller 2, an elastic push plate machine 4, a position sensor 11, a driver 6 and a controller. The upper end surface of the elevator 1 contains the mineral wool sound absorption board 5, and the elevator 1 rises or falls to drive the mineral wool sound absorption board 5 to rise or fall. The conveying rubber roller 2 is located at the front end of the elevator 1, at the front end of the pushing direction of the mineral wool sound absorption board 5, and the conveying rubber roller 2 can convey the mineral wool sound absorption board 5. The elastic push plate machine 4 is arranged at the upper part of the elevator 1, and the height of the elastic push plate machine 4 is adjusted according to the thickness of the uppermost layer of mineral wool sound absorption board 5, so that the pushing height and force between the elastic push plate machine 4 and the mineral wool sound absorption board 5 are kept appropriate. The elastic push plate machine 5 pushes the uppermost layer of mineral wool sound absorption board 5 onto the conveying rubber roller 2, and then returns to the initial position. The elevator 1 is raised to drive the second layer of mineral wool sound absorption board 5 to rise. The elastic push plate machine 4 pushes the second layer of mineral wool sound absorption board 5 onto the conveying rubber roller 2. In this way, the process is repeated until all the mineral wool sound absorption boards 5 are pushed onto the conveying rubber roller 2.

[0041] The position sensor 11 is located on the side of the upper end surface of the elevator 1 and can detect the mineral wool sound-absorbing board 5. The driver 6 is installed at the front end of the elastic pusher 4. The controller is electrically connected with the position sensor 11 and the driver 6. The number of the position sensor 11, the elastic pusher 4 and the driver 6 is two. The two position sensors 11 are respectively located on the two sides of the mineral wool sound-absorbing board 5, and the connection lines of the two position sensors 11 are perpendicular to the length direction of the mineral wool sound-absorbing board 5, that is, the distance between the two position sensors 11 and the front end surface or the rear end surface of the mineral wool sound-absorbing board 5 is equal. The two position sensors 11 are defined as a first position sensor and a second position sensor. The two elastic pushers 4 are defined as a first elastic pusher and a second elastic pusher. The two drivers 6 are defined as a first driver and a second driver. The first driver is located at the front end of the first elastic pusher. The second driver is located at the front end of the second pusher. The first position sensor is located on the side close to the first driver. The second position sensor is located on the side close to the second driver.

[0042] In specific implementation, the elastic pusher 4 pushes the mineral wool sound-absorbing board 5 forward. The front end surface of the mineral wool sound-absorbing board 5 moves forward to the shielding position sensor 11. The position sensor 11 detects the time when the front end surface of the mineral wool sound-absorbing board 5 appears. If the time when the first position sensor 11 detects the left side of the front end of the mineral wool sound-absorbing board 5 appears is the same as the time when the second position sensor detects the right side of the front end of the mineral wool sound-absorbing board 5 appears, the mineral wool sound-absorbing board 5 moves along the axis perpendicular to the conveying rubber roller 2, and there is no push skew. The first driver and the second driver do not work and are in an invalid state. The mineral wool sound-absorbing board 5 continues to move forward. If the time when the first position sensor 11 detects the left side of the front end of the mineral wool sound-absorbing board 5 appears is different from the time when the second position sensor detects the right side of the front end of the mineral wool sound-absorbing board 5 appears, the two position sensors 11 transmit signals to the controller. The controller controls the driver 6 on the side of the mineral wool sound-absorbing board 5 which appears later to start. The driver 6 pushes the mineral wool sound-absorbing board 5 on the delayed side to move forward, so that the mineral wool sound-absorbing board 5 on the delayed side can catch up with the other side, and then the whole mineral wool sound-absorbing board 5 keeps moving along the axis perpendicular to the conveying rubber roller 2, avoiding the push skew. For example, the first position sensor 11 detects the time when the left side of the front end of the mineral wool sound-absorbing board 5 appears first. The second position sensor detects the time when the right side of the front end of the mineral wool sound-absorbing board 5 appears. The time difference between the two indicates that the right side of the mineral wool sound-absorbing board 5 moves slower than the left side, and there is a delay. The two position sensors 11 transmit signals to the controller. The controller controls the second driver on the right side to start. The second driver applies an additional pushing force to the right side of the mineral wool sound-absorbing board 5, so that the right side of the mineral wool sound-absorbing board 5 accelerates to catch up with the left side. The whole mineral wool sound-absorbing board 5 keeps moving along the axis perpendicular to the conveying rubber roller 2, and corrects the skewed mineral wool sound-absorbing board 5.

[0043] It should be noted that the length of the time difference detected by the two position sensors 11, the driving force and acceleration of the driver 6 are adjusted through a limited number of tests.

[0044] Preferably, the driver 6 comprises: a gas source 61, a gas pipe 63 and a gas bag 62 connected in sequence. When the driver 6 needs to start accelerating the mineral wool sound-absorbing board 5, the gas source 61 inflates the gas bag 62 through the gas pipe 63, and the gas bag 62 is inflated to push the mineral wool sound-absorbing board 5 on the slow side to move forward, so that it can catch up with the other side, that is, to correct the skewed mineral wool sound-absorbing board 5. The inflation amount of the gas bag 62 is adjusted by detecting the length of the time difference, and when the time difference is longer, the inflation amount of the gas bag 62 is increased, and if the time difference is shorter, only a small amount of gas needs to be filled into the gas bag 62.

[0045] Preferably, the upper plate machine for mineral wool sound-absorbing board of the present application further comprises: a traction assembly 7 installed on the elastic push plate machine 4 and capable of pulling the front end of the upper surface of the mineral wool sound-absorbing board 5. When the two elastic push plate machines 4 push the mineral wool sound-absorbing board 5 forward, the traction assembly 7 pulls the middle part of the front end of the upper surface of the mineral wool sound-absorbing board 5. On the one hand, the traction assembly 7 guides the front end of the mineral wool sound-absorbing board 5 to move forward, avoiding left and right skew; on the other hand, the traction assembly 7 lifts the front end of the mineral wool sound-absorbing board 5 a little, reducing the frictional resistance with the next layer of mineral wool sound-absorbing board 5, avoiding scratching between the mineral wool sound-absorbing boards 5 during the pushing process, and affecting the decorative surface. More importantly, the traction assembly 7 and the two elastic push plate machines 4 form a triangular structure, firmly controlling the forward direction of the mineral wool sound-absorbing board 5, avoiding pushing the mineral wool sound-absorbing board 5 skew.

The suction cup 72 adsorbs and fixes the mineral wool sound-absorbing board 5, and the elastic traction rope 71 can not only constrain and guide the direction of the mineral wool sound-absorbing board 5, but also can be adjusted adaptively according to the movement of the mineral wool sound-absorbing board 5.

[0047] Preferably, the elastic pusher 4 comprises a conveying belt 41, an elastic member 42 and a pusher 43, the conveying belt 41 is arranged on the elevator 1 at intervals, the elastic member 42 is fixedly installed on the lower end surface of the conveying belt 41 and can stretch in the vertical direction, and the pusher 43 is installed on the lower end surface of the elastic member 42. Two elastic pushers 4 are arranged in parallel, each of the elastic pushers 4 comprises the fixedly connected conveying belt 41, elastic member 42 and pusher 43, one motor is used to drive the two parallel synchronous conveying belts 41, and one motor is used to drive the transmission shaft to rotate, and the transmission shaft drives the two conveying belts 41 to rotate synchronously. In specific implementation, the elastic member 42 adjusts the height of the pusher 43 according to the height of the mineral wool sound-absorbing plate 5, the pusher 43 realizes the grabbing of the mineral wool sound-absorbing plate 5, the conveying belt 41 drives the elastic member 42 to move forward, the elastic member 42 drives the pusher 43 to move forward, and the pusher drives the mineral wool sound-absorbing plate 5 to move forward.

[0048] Preferably, the plate feeding machine suitable for the mineral wool sound-absorbing plate of the present application further comprises a motor and a transmission shaft 8, the transmission shaft 8 is connected with one elastic pusher 4 at each end and connected with a traction rope 71 in the middle, the motor drives the transmission shaft 8 to rotate, and the traction rope 71 is wound on the transmission shaft 8 in the clockwise direction. In specific implementation, the motor drives the transmission shaft 8 to rotate clockwise, the transmission shaft 8 drives the two conveying belts 41 to rotate synchronously in the clockwise direction, the conveying belts 41 drive the elastic pusher 4 to move forward, at the same time, the transmission shaft 8 rotates clockwise to drive the traction rope 71 to constantly disengage from the transmission shaft, that is, the length of the traction rope 71 between the transmission shaft 8 and the suction cup 72 constantly elongates, which is just suitable for the traction requirement in the forward movement of the mineral wool sound-absorbing plate 5; when the elastic pusher 4 is reset backward, the motor drives the transmission shaft 8 to rotate counterclockwise, the transmission shaft 8 drives the two conveying belts 41 to rotate synchronously in the counterclockwise direction, the conveying belts 41 drive the elastic pusher 4 to move backward to reset, at the same time, the transmission shaft 8 drives the traction rope 71 to constantly wind on the transmission shaft 8 to perform rewinding.

[0049] On the other hand, the present application further provides a plate feeding method suitable for a mineral wool sound-absorbing plate, which adopts the plate feeding machine for the mineral wool sound-absorbing plate, and the method comprises the following steps:

[0050] The elastic pusher 4 is started, the elastic pusher 4 pushes the mineral wool sound-absorbing plate 5 forward, the position sensor 11 detects the position of the front end surface of the mineral wool sound-absorbing plate 5, if there is a time difference in the arrival time of the front end surface of the mineral wool sound-absorbing plate 5 detected by the two position sensors 11, a signal is sent to the controller, and the controller controls the drive 6 on one side of the mineral wool sound-absorbing plate 5 detected later to push the mineral wool sound-absorbing plate 5 forward.

[0051] Preferably, the plate feeding method further comprises:

[0052] The suction cup 72 is adsorbed to the middle of the upper surface of the front end of the mineral wool sound absorption plate 5, the motor drives the transmission shaft 8 to rotate clockwise, the transmission shaft 8 drives the elastic push plate machine 4 to push the mineral wool sound absorption plate 5 forward, and synchronously drives the traction rope 71 to be elongated, and the traction rope 71 pulls the middle part of the fixed mineral wool sound absorption plate 5.

The mounting member can be a mounting plate or a rectangular frame. The conveying belt 41 is fixedly connected with the upper surface of the rectangular frame, and the lower surface of the rectangular frame is fixedly connected with the elastic member 42. This facilitates the mounting of the elastic member 42 on the conveying belt 41 and ensures the stable operation of the elastic member 42 and reduces the upward extrusion deformation of the elastic member 42 on the conveying belt 41.

[0054] Preferably, the elastic member 42 is a spring, which is vertically arranged, and the upper end surface of the spring is fixedly connected with the conveying belt 41, and the lower end surface of the spring is fixedly connected with the pusher 43. When the pusher 43 approaches the mineral wool plate 5, the spring starts to work. If the mineral wool sound absorption plate 5 is relatively low, the spring only produces a small compression, so that the pusher 43 can gently and stably contact the mineral wool sound absorption plate 5, and enough pushing force is ensured. If the mineral wool sound absorption plate 5 is relatively high, the spring will increase the compression amount according to the increased resistance, so as to automatically adjust the effective height of the push plate, thereby avoiding excessive extrusion on the mineral wool sound absorption plate 5. This self-adaptive adjustment mechanism enables the push plate to always maintain the optimal pushing height and intensity under various conditions of the mineral wool plate, effectively protects the integrity of the mineral wool sound absorption plate 5, and improves the efficiency and reliability of the mineral wool sound absorption plate 5 conveying.

[0055] Preferably, the pusher 43 comprises a guide plate, a pressing plate, a push plate and a tail plate connected in sequence. The guide plate and the pressing plate are arranged at an acute angle, the pressing plate is horizontally arranged, the push plate is vertically arranged, and the tail plate is in a V-shaped structure. The guide plate plays a guiding role, the pressing plate fixes the mineral wool sound absorption plate 5 downward, the push plate is used to push the mineral wool sound absorption plate 5 to move forward, and the tail plate can avoid the bottom of the push plate from scratching the mineral wool plate 5.
