Description

Technical Field

[0001] The invention relates to the technical field of gypsum board processing, and in particular to an automatic integrated cutting and drying device for paper-faced gypsum boards and a control method. Background Art

[0002] After the gypsum board wet board is formed, it needs to be cut into fixed sizes and then dried. In fact, in the gypsum board wet board forming process, generally only a long strip of gypsum board wet board can be formed, and then gradually cut into several gypsum board wet boards. The cut gypsum board wet boards are generally transported along the length direction.

[0003] After the upper surface of the wet gypsum board is formed, the upper surface of the wet board is basically solidified, and the curing effect of the bottom surface is not good. In order to avoid the bottom surface from being scratched on the roller when entering the dryer, the wet gypsum board needs to be turned over for secondary drying. However, since the wet gypsum board is still transported along the length direction after being formed and cut, the turning mechanism needs to reserve a turning space for the gypsum board to turn over along the length direction. The turning space has a side length of at least not less than the length of the gypsum board. Moreover, the gypsum board single board is dried, transported and dried in sequence. The whole process is inefficient, and each batch of gypsum boards is transported out of the dryer after drying, which also has a certain impact on the drying effect of other gypsum boards.

[0004] In summary, the prior art has the following technical problems: a certain amount of turning space needs to be reserved for the transportation and turning of the gypsum board veneer in the length direction, and the transportation and drying of the gypsum board veneer are carried out in batches, which can easily lead to low efficiency of the entire process and poor gypsum board drying effect.

[0062] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0063] like Figure 1As shown, the present invention provides an integrated automatic cutting and drying device for paper-faced gypsum board, which comprises a slitting machine 1, a single board feeding mechanism 2, a single board microwave dryer 3, a material adding and turning conveying mechanism 4, a multi-board feeding mechanism 5 and a multi-board dryer 6, wherein the slitting machine 1 is used to slit the wet gypsum board into preset sizes; the single board feeding mechanism 2 is connected to the unloading part of the slitting machine 1, and is used to convey the slit wet gypsum board; the single board microwave dryer 3, whose inlet end is connected to the end of the single board feeding mechanism 2, and the single board feeding mechanism 2 is used to feed the wet gypsum board into the single board microwave dryer 3 directly Drying is carried out; a material-increasing and overturning conveying mechanism 4, whose upstream end is connected to the output end of the single-board microwave dryer 3, and the conveying direction of the material-increasing and overturning conveying mechanism 4 is perpendicular to the discharge direction of the single-board microwave dryer 3; a multi-board feeding mechanism 5, whose upstream end is connected to the downstream end of the material-increasing and overturning conveying mechanism 4, and the width of the multi-board feeding mechanism 5 is at least not less than twice the width of the wet gypsum board, so as to convey multiple wet gypsum boards at the same time; a multi-board dryer 6, whose inlet section is connected to the output end of the multi-board feeding mechanism 5, and the multi-board dryer 6 is used to simultaneously receive multiple wet gypsum boards and perform secondary drying.

[0064] In the embodiment of the present invention, a material-increasing and overturning conveying mechanism 4 is provided, which gradually adjusts the transportation and drying process of a single gypsum board into the transportation and drying of multiple gypsum boards through transportation and overturning, thereby increasing the number of gypsum boards that have completed drying in the same batch, and improving the transportation and drying efficiency of the gypsum boards by at least two times while ensuring the drying effect; and through the material-increasing and overturning conveying mechanism 4, the transportation direction of the gypsum boards is adjusted from the length direction to the width direction before the gypsum boards enter the overturning work, thereby reducing the overturning space that needs to be reserved for the overturning part, reducing the transportation time of the gypsum boards, saving a certain amount of machine manufacturing costs, and improving the transportation efficiency of the gypsum boards.

[0065] Traditional dryers often dry gypsum boards for a period of time and then discharge them, and then dry the next section of gypsum boards. In order to improve the drying efficiency of wet gypsum boards, a single-board microwave dryer 3 is set up for the first drying. During this process, the next section of gypsum boards needs to wait, which takes a long time and has low drying efficiency. In order to improve the drying efficiency of gypsum boards, the single-board microwave dryer 3 and the multi-board dryer 6 in the present invention both have multi-layer drying and conveying channels 8, wherein the drying and conveying channels 8 are composed of multiple first transport rollers 81, and the first transport rollers 81 are coaxially connected to the first drive shaft 82.

[0066] The present invention transports the wet gypsum board to the front end of the single board microwave dryer 3 through the single board loading mechanism 2. The single board loading mechanism 2 is composed of a plurality of second transport rollers 21. The second transport rollers 21 form a single-row transport roller group. A second drive shaft 22 is coaxially arranged on the second transport roller 21. A first mounting frame 23 is arranged on the side of the second transport roller 21. The second drive shaft 22 is rotatably mounted on the first mounting frame 23. A first fixed seat 24 is arranged at the end of the first mounting frame 23. The end of the first mounting frame 24 is rotatably mounted on the first fixed seat 24. The tilting lifting mechanism 7 is arranged at the bottom of the first mounting frame 23.

[0067] The single batch of gypsum boards in the present invention that is transported to the multi-board loading mechanism 5 via the material adding and flipping conveying mechanism 4 contains multiple gypsum boards (at least two). The multi-board loading mechanism 5 of the present invention transports multiple gypsum boards as a single batch at the same time. The multi-board loading mechanism 5 is composed of multiple sixth transport rollers 51, and the sixth transport rollers form at least two rows of transport roller groups. The sixth transport roller 51 is coaxially connected with the sixth drive shaft 52, and a second mounting frame 53 is arranged on the side of the sixth transport roller 51. The sixth drive shaft 52 is rotatably mounted on the second mounting frame 53, and a second fixed seat 54 is arranged at the end of the second mounting frame 53. The end of the second mounting frame 53 is rotatably mounted on the second fixed seat 54; the inclined lifting mechanism 7 is arranged at the bottom of the second mounting frame 53.

[0068] In the present invention, in order to enable the single-sheet loading mechanism 2 and the multi-sheet loading mechanism 5 to dock with the corresponding drying conveying channel 8 during the loading process, the drying conveying channel 8 is set to be inclined, and an inclined lifting mechanism 7 is provided at the bottom of the single-sheet loading mechanism 2 and the multi-sheet loading mechanism 5. The inclined lifting mechanism 7 is used to make the downstream end of the single-sheet loading mechanism 2 and / or the multi-sheet loading mechanism 5 tilt upward around its upstream end to dock with the drying conveying channels 8 of different layers.

[0069] The drying and conveying passage 8 at the bottom is in a horizontal state, and the inclination angle of the drying and conveying passage 8 decreases gradually from top to bottom.

[0070] In order to drive the single-plate feeding mechanism 2 and the multi-plate feeding mechanism 5 to rotate, the tilting lifting mechanism 7 of the present invention mainly adopts the following preferred embodiments, such as Figure 2 and Figure 3 As shown, the tilt lifting mechanism 7 includes a sliding groove 71 arranged on the lower end surfaces of the first mounting frame 23 and the second mounting frame 53, a sliding seat 72 slidably arranged in the sliding groove 71, a lifting threaded shaft 73 connected to the lower end of the sliding seat 72, and a threaded barrel 74 threadedly connected to the end of the lifting threaded shaft 73; a first driving motor 75 is connected to the bottom of the threaded barrel 74, the threaded barrel 74 is connected to the output end of the first driving motor 75, and the sliding seat 72 is rotatably connected to the upper end of the lifting threaded shaft 73.

[0071] The process of the tilting and lifting mechanism 7 driving the end of the first mounting frame 23 to rise and fall is that the first driving motor 75 drives the threaded cylinder 74 to rotate. Under the rotation of the threaded cylinder 74 and the limiting action of the upper sliding seat 72, the lifting threaded shaft 73 gradually moves upward, driving the end of the first mounting frame 23 to move upward. During the upward movement of the first mounting frame 23, the sliding seat 72 slides in the sliding groove 71.

[0072] In order to realize the overturning and material addition transmission of the gypsum board, the present invention is provided with a material addition overturning and conveying mechanism 4. The material addition overturning and conveying mechanism 4 mainly adopts the following preferred embodiments, such as Figure 1 and Figure 2 As shown, the material adding and turning conveying mechanism 4 includes a lifting and conveying roller 41, a first conveying roller 42 and a second conveying roller 43 which are sequentially arranged at the downstream end of the single plate microwave dryer 3; the lifting and conveying roller 41 can be lifted and lowered to connect with the drying conveying channels 8 of different layers.

[0073] Among them, the lifting and transmission roller 41 can be lifted and lowered to connect with the drying conveying channels 8 on different layers. The lifting and transmission roller 41 is composed of multiple third transport rollers 411, and the first transmission belt 412 is arranged on every two third transport rollers 411; a lifting frame 413 is arranged on the side of the third transport roller 411, and a hydraulic cylinder 414 is arranged under the lifting frame 413. The hydraulic cylinder 414 is driven to drive the lifting frame 413 to perform lifting and lowering movements. The hydraulic cylinder 414 in this embodiment drives the lifting frame 413 to lift and lower as a whole.

[0074] In the above embodiment, starting from the first transmission roller 42, the transmission direction of the wet gypsum board changes. On the third transport roller 411, it is transported along the length direction, and when it reaches the first transmission roller 42, it starts to be transported along the width direction of the wet gypsum board. The first transmission roller 42 is composed of a plurality of fourth transport rollers 421. The fourth transport roller 421 is provided with a second transmission belt 422. The second transmission belt 422 is interspersed between each group of third transport rollers 411. The second transmission belt 422 is used to drive the wet gypsum board to be transported along the width direction.

[0075] In the above embodiment, during the process of being transported to the top of the first transmission belt 412, the wet gypsum board is gradually transported to the top of the second transmission belt 422. During the forward transportation of the first transmission belt 412, the second transmission belt 422 remains stationary. After the transmission of the first transmission belt 412 is completed, the fourth transport roller 421 is driven to drive the second transmission belt 422 to transport forward.

[0076] The wet gypsum board is flipped during the transmission process of the second transmission belt 422. In order to flip the wet gypsum board, the present invention makes the following design: a flip motor 423 is arranged between the second transmission belts 422, and a flip supply plate 424 and a flip connecting plate 425 are arranged on the flip motor 423; the flip motor 423 rotates to drive the flip supply plate 424 and the flip connecting plate 425 to rotate.

[0077] In order to restore the wet gypsum board to its initial transmission state along the length direction, the present invention arranges a second transmission roller. The second transmission roller 43 and the first transmission roller 42 also increase the number of gypsum boards in a single batch during the transmission process. The second transmission roller 43 is composed of a plurality of fifth transport rollers 431, and the fifth transport rollers 431 are interspersed between the second transmission belts 422. The fifth transport roller 431 is coaxially connected to a fifth drive shaft 432, and the fifth transport roller 431 corresponds to the sixth transport roller 51 in a row.

[0078] Originally, one gypsum board was transported at the same time in a single batch. Now, the number of gypsum boards transported in a single batch is determined by the number of columns set by the sixth transport roller 51. Each column of the sixth transport roller 51 transports one gypsum board. Assuming that the number of columns set by the sixth transport roller 51 is 2, during the transportation process, the second transmission belt 422 transports the first wet gypsum board to the end of the second transmission belt 422, and then the second transmission belt 422 stops transmitting forward, and the fifth transport roller 431 drives the wet gypsum board to enter above the first column of the sixth transport roller 51. Then, the second transmission belt 422 transports the second wet gypsum board to the position on the second transmission belt 422 corresponding to the second column of the sixth transport roller 51, and then the second transmission belt 422 stops transmitting forward, and the fifth transport roller 431 drives the wet gypsum board to enter above the second column of the sixth transport roller 51. The two gypsum boards in the single batch are in place. At this time, the two gypsum boards are transported forward at the same time by the sixth transport roller 51.

[0079] In order to avoid the wet gypsum board head not being flush with the drying conveying channel and colliding with it after the inclined lifting mechanism 7 lifts the single-board feeding mechanism 2 and the multi-board feeding mechanism 5, a specific detection structure and a lifting and transporting component 9 are set up, wherein the detection structure is mainly as follows, Figure 2 and Figure 3 As shown, an infrared transmitter 83 is provided on the first driving shaft 82, and the infrared transmitter 83 is installed at the side center position of the first driving shaft 82 located at the front end. The infrared transmitter is used to emit infrared rays. Detection receivers 10 are provided on the sides of the second driving shaft 22 and the sixth driving shaft 52. The detection receiver 10 and the infrared transmitter 83 are arranged on the same straight line. The detection receiver 10 is used to receive the infrared rays emitted by the infrared transmitter 83 to detect whether the upper end surfaces of the single-plate feeding mechanism 2 and the multi-plate feeding mechanism 5 are aligned with the plane where the drying conveying channel 8 is located.

[0080] When the detection receiver 10 does not detect the infrared signal emitted by the infrared transmitter 83, it means that the corresponding single-board loading mechanism 2 and the multi-board loading mechanism 5 are not flush with the corresponding drying and conveying channel 8. At this time, it is necessary to lift the wet gypsum board by lifting the transfer component 9 so that it is higher than the drying and conveying channel 8 to avoid hitting the drying and conveying channel 8.

[0081] The lifting and transfer component 9 is arranged between the multi-board loading mechanism 5 and the multi-board dryer 6, and between the single-board loading mechanism 2 and the single-board microwave dryer 3. The lifting and transfer component 9 is used to lift the heads of multiple wet gypsum boards transported to the front end of the multi-board dryer 6 so that the heads of the wet gypsum boards are slightly higher than the drying conveying channel 8.

[0082] The lifting and transporting component 9 of the present invention mainly adopts the following preferred embodiments, such as Figure 2 and Figure 3 The lifting and transfer component 9 includes a transfer roller 91 arranged between the first transport roller 81 and the sixth transport roller 51, a connecting frame 92 arranged on the side of the transfer roller 91, and a tilting frame 93 arranged on the connecting frame 92; the connecting frame 92 is connected to the second mounting frame 53, the transfer roller 91 is rotatably arranged in the tilting frame 93, the end of the tilting frame 93 is rotatably arranged on the connecting frame 92, and a lifting cylinder 94 is arranged on the connecting frame 92, and the output end of the lifting cylinder 94 abuts against the end of the tilting frame 93 away from the rotation point.

[0083] The lifting cylinder 94 drives the end of the tilting frame 93 to move upward, causing the tilting frame 93 to tilt, and the first transfer roller 91 is lifted as a whole, so that the wet gypsum board is lifted to a certain position during the transmission process, and then enters the drying and conveying channel 8.

[0084] In summary, the present invention provides a control method for an automatic gypsum board cutting and drying device, comprising the following steps:

[0085] Step 100, the slitting machine 1 cuts the wet gypsum board into preset sizes;

[0086] Step 200, the single board feeding mechanism 2 is adjusted by the tilting and lifting mechanism 7 so that the single board feeding mechanism 2 is tilted to dock with the drying and conveying channels 8 of different layers, and the wet gypsum board is conveyed to the corresponding drying and conveying channel 8 of the single board microwave dryer 3 through the single board feeding mechanism 2 after cutting;

[0087] Step 300, the material adding and turning conveying mechanism 4 transports and turns the wet gypsum boards that have completed the drying in batches, and transports them to the front end of the multi-board feeding mechanism 5 corresponding to different column positions;

[0088] Step 400, after the multi-board loading mechanism 5 receives the wet gypsum boards to a full row, the multi-board loading mechanism 5 is adjusted by the tilting and lifting mechanism 7 so that the multi-board loading mechanism 5 is tilted to dock with the drying and conveying channels 8 on different layers, and the wet gypsum boards are conveyed to the corresponding drying and conveying channels 8 of the multi-board dryer 6 via the multi-board loading mechanism 5.

[0089] In the above embodiment, the time for the wet gypsum board to be dried in the single-board microwave dryer 3 is t1, the time for the wet gypsum board to be dried in the multi-board dryer 6 is t2, and the time for the wet gypsum board to be discharged from the single-board microwave dryer 3 and transported to the feeding end of the multi-board dryer 6 via the material-increasing turning conveying mechanism 4 and the multi-board loading mechanism 5 is t3; wherein, t1<t2, and t2=t3.

[0090] In actual application, in order to reduce the time that wet gypsum boards wait for a full row at the feeding end of the multi-board feeding mechanism 5, it is necessary to make t1 < t2. In the present invention, the single-board microwave dryer 3 has a high efficiency, which just makes t1 < t2, and secondary drying is required in the multi-board dryer 6. The condition of t1 < t2 (uneven drying time for the two times) does not affect the drying effect of the gypsum boards. In addition, in order to ensure that the wet gypsum boards can enter the multi-board dryer 6 immediately after being transported to the feeding end of the multi-board dryer 6, it is necessary to make t2 = t3. When t2 = t3, when a batch of wet gypsum boards is transported to the feeding end of the multi-board dryer 6, another batch of wet gypsum boards has just been dried. At this time, the loading work of a batch of wet gypsum boards and the unloading work of another batch of wet gypsum boards are carried out simultaneously. The time when a batch of gypsum boards starts to dry is exactly the time when the wet gypsum boards in the single-board microwave dryer 3 are unloaded after the first drying is completed.
