Description
TECHNICAL FIELD
[0001] The embodiment of the present application relates to the technical field of gypsum board production, and particularly relates to a kind of automatic waste equipment for cutting not broken gypsum board. BACKGROUND
[0002] The production process of gypsum board mainly includes batching, mixing and stirring, forming, continuous conveying, cutting, drying and stacking, wherein the cutting process generally sets a liftable intercepting plate on the conveying roller belt near the cutting machine position to intercept the transported gypsum board, and the gypsum board is cut into boards of the same length by the cutting machine. In the continuous production process of gypsum board, the reliability of the cutting process directly affects the efficiency of the production line.
[0003] The core problem faced by the current industry is that when the cutting knife fails to completely cut the board, the unseparated board will cause subsequent roller stacking disorder (i.e., two control disorder), which will force the entire line to stop. The existing technology relies on manual visual inspection to detect the uncut state, which has the problems of response lag and high missed detection rate, further exacerbating downtime and scrap rate.
[0004] In addition, the traditional method lacks an automatic closed-loop control mechanism, and the manual intervention in the waste disposal operation makes it difficult to perform the waste disposal action in real time, which may cause the production loss to continue to expand. In order to improve the above technical problems, it is urgent to provide a system that can automatically identify the cutting knife failure state to dynamically diagnose the cutting abnormal state and perform the waste disposal operation in linkage, so as to eliminate the efficiency bottleneck of manual intervention.

[0039] The embodiments of the present application will be described in detail with specific embodiments, and those skilled in the art can easily understand other advantages and effects of the present application from the disclosure. Obviously, the described embodiments are part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0040] As shown in the drawings, the present embodiment provides a kind of for cutting automatically waste equipment of gypsum board, comprising: Figs. 1 to 3 Conveying roller belt 1 is used to transport the gypsum board to be cut, conveying roller belt 1 is sequentially provided with rack 2, intercepting plate 3 and sorting roller 4 along the direction of gypsum board transport, intercepting plate 3 is intercepted or passed by lifting to transport the gypsum board on conveying roller belt 1;
[0041] Waste roller belt 5 is arranged at one side of conveying roller belt 1 and opposite sorting roller 4, and sorting roller 4 can make the gypsum board transported thereon shift to conveying roller belt 1 or waste roller belt 5;
[0042] Cutting knife 6 is arranged on rack 2 and is used to cut the gypsum board below rack 2, and air cylinder 201 for controlling the lifting of cutting knife 6 is installed on rack 2;
[0043] First proximity switch 202 and second proximity switch 203 are installed on one side of rack 2, and one side of cutting knife 6 is provided with trigger block 7;
[0044] When cutting knife 6 is at the highest position, trigger block 7 contacts the detection end of first proximity switch 202, and first proximity switch 202 is triggered when cutting knife 6 descends to be separated from the detection end of first proximity switch 202;
[0045]
[0046] When the cutter 6 is lowered to a height capable of cutting the gypsum board, the trigger block 7 contacts the detection end of the second proximity switch 203 and triggers the second proximity switch 203;
[0047] The processor 204 is used for receiving the trigger signals of the first proximity switch 202 and the processor 204, and determining the cutting state of the gypsum board according to the interval of the triggering of the first proximity switch 202 and the second proximity switch 203 in sequence, so that the processor 204 can control the sorting roller 4 according to the cutting state.
[0048] The present application realizes real-time and accurate determination of the cutting state and full-automatic waste control through the timing mechanism of the double proximity switches and the trigger block in the above scheme, calculates the effective stroke of the cutter by using the signal interval time of the first proximity switch and the second proximity switch, and automatically determines that the gypsum board is not cut once the time is exceeded, so that the processor synchronously links the sorting roller to guide the uncut board into the waste roller, avoids the production line shutdown caused by the disorder of the board, and simultaneously triggers the alarm system, thereby improving the comprehensive efficiency of the production line and reducing the waste rate and labor cost.
[0049] Specifically, when the cylinder 201 drives the cutter 6 to descend from the highest position, the trigger block 7 is separated from the first proximity switch 202 to trigger the timing signal; if the cutter 6 normally cuts the gypsum board, the second proximity switch 203 will be triggered within a predetermined time; if the second proximity switch 203 is not triggered after the time is exceeded, the processor 204 determines that the cutting state is not cut, and immediately controls the sorting roller 4 to turn to guide the gypsum board into the waste roller 5.
[0050] Notably, the conveying roller 1 is supported by a plurality of transmission rollers distributed at equal intervals and transports the gypsum board, and the waste roller 5 is supported by a plurality of numerical control direction-changing transmission rollers and guides the transportation of the gypsum board; when the conveying roller 1 transports the gypsum board to the intercepting plate position, the lifting type intercepting plate 3 is lifted to block the board, and the intercepting plate 3 is pre-set at the corresponding position on the conveying roller 1 to ensure that the gypsum board can be intercepted and limited in the specified area after the intercepting plate 3 is lifted; different proximity switches are divided into two types of normally open and normally closed, so the triggering conditions of the first proximity switch 202 and the second proximity switch are different; the signal processor receives the signal and judges the processing result, and controls the different running states of the waste roller 5 according to the processing result; all the above are conventional technical means in the gypsum board production line, and will not be described in detail here.
[0051] Among them, the inner side of the rack 2 is provided with at least two longitudinally distributed slide rails 205, the top end of the cutter 6 is slidably connected to all the slide rails 205 through a movable knife holder 601, and the output end of the cylinder 201 is connected to the movable knife holder 601, so that the output end of the cylinder 201 can be extended or retracted to vertically lift the movable knife holder 601 along the slide rails 205.
[0052] Specifically, the design of the movable cutter seat 601 vertically lifting along the longitudinal slide rail 205 eliminates the lateral deviation in the cutting process of the cutter 6, ensures the alignment accuracy of the trigger block 7 with the double proximity switches, avoids the misjudgment 2 caused by mechanical vibration, and limits the gypsum board transported on the conveying roller belt 1 to the preset position below the rack 2 by the intercepting plate 3. When the movable cutter seat 601 completes the lowering action, it ensures that the cutter 6 can cut the preset area of the gypsum board below.
[0053] The machine frame 2 is provided with a longitudinal sliding groove 206 on the side, and the trigger block 7 is provided with a connecting block 701 penetrating the sliding groove 206 and connected to the movable cutter seat 601. The sliding groove 206 is located between the first proximity switch 202 and the second proximity switch 203, and one side of the trigger block 7 penetrates the sliding groove 206 through the connecting block 701 and is connected to the cutter 6;
[0054] When the connecting block 701 slides to the uppermost of the sliding groove 206, the trigger block 7 contacts the detection end of the first proximity switch 202.
[0055] When the connecting block 701 slides to the lowermost of the sliding groove 206, the trigger block 7 contacts the detection end of the second proximity switch 203, and the cutter 6 descends to a height capable of cutting the gypsum board.
[0056] Specifically, the trigger block 7 is fixed to the side wall of the movable cutter seat 601 through the connecting block 701. When the connecting block 701 moves up and down in the sliding groove 206 of the machine frame 2, it accurately covers the detection interval of the first proximity switch 202 and the second proximity switch 203. The up-down limit design of the sliding groove 206 ensures that the trigger position is constant.
[0057] When the cutter 6 starts to descend from the top point, the first trigger 703 at the top of the trigger block 7 separates from the state of adhering to the detection end of the first proximity switch 202, so that the first proximity switch 202 sends a signal to the processor 204.
[0058] When the cutter 6 descends to the cutting position, the second trigger 705 at the bottom of the trigger block 7 contacts the detection end of the second proximity switch 203, so that the second proximity switch 203 sends a signal to the processor 204.
[0059] When the cutter 6 rises to the top point, the first trigger 703 at the top of the trigger block 7 contacts the detection end of the first proximity switch 202, so that the first proximity switch 202 is reset to the off state.
[0060] During the lifting process of the lifting knife seat 601 together with the trigger block 7, it is necessary to ensure that the trigger block 7 can contact the detection end of the first proximity switch 202 and the second proximity switch 203, and it is necessary to ensure that the trigger block 7 can fully contact the detection end of the first proximity switch 202 when it is in the highest position, and reduce the contact force with the detection end of the second proximity switch 203 during the process of descending to the lowest position, so as to prevent damage to the second proximity switch.
[0061] Wherein, the trigger block 7 is located directly below the first proximity switch 202 and directly above the second proximity switch 203, the top end of the trigger block 7 is provided with a first threaded hole 702 and a first trigger piece 703 is threadedly connected through the first threaded hole 702, the trigger block 7 contacts the detection end of the first proximity switch 202 and triggers the first proximity switch 202 through the first trigger piece 703 when it rises to the highest position, and the inside of the trigger block 7 is provided with an inner sliding cavity 704 and a second trigger piece 705 is connected at the bottom of the trigger block 7 through the inner sliding cavity 704, the trigger block 7 contacts the detection end of the second proximity switch 203 and triggers the second proximity switch 203 through the second trigger piece 705 when it descends.
[0062] The first trigger piece 703 is composed of a threaded rod 7031 and a first trigger piece 7032, the threaded rod 7031 is connected in the first threaded hole 702, the depth of the first threaded hole 702 is greater than the length of the threaded rod 7031, the first trigger piece 7032 is located directly below the detection end of the first proximity switch 202, and the threaded rod 7031 rotates in the inner sliding cavity 704 to adjust the distance between the first trigger piece 7032 and the trigger block 7.
[0063] Specifically, the threaded rod 7031 of the first trigger piece 703 is screwed into the first threaded hole 702 at the top of the trigger block 7, and the initial gap between the first trigger piece 7032 and the detection end of the first proximity switch 202 can be changed by rotating adjustment, which compensates for the accumulated error of mechanical wear after long-term operation of the equipment, ensures that the cutter can reliably trigger the first proximity switch every time it is reset, and eliminates the risk of signal loss caused by vibration.
[0064] Wherein, the second trigger piece 705 includes a sliding block 7051 movably connected in the inner sliding cavity 704, the bottom end of the sliding block 7051 is provided with a connecting rod 7052 penetrating the trigger block 7, the bottom end of the connecting rod 7052 is provided with a second trigger piece 7053 for contacting the second proximity switch 203, and the second trigger piece 7053 is located directly below the detection end of the second proximity switch 203.
[0065] The diameter of the sliding block 7051 is smaller than the inner diameter of the inner sliding cavity 704, and the sliding block 7051 is located at the bottommost part inside the trigger block 7 in the initial state, and the sliding block 7051 rises in the trigger block 7 which is continuously descending when the second trigger piece 7053 contacts the detection end of the second proximity switch 203.
[0066] Specifically, the slider 7051 of the second trigger piece 705 keeps an axial floating gap in the inner sliding cavity 704, when the second trigger piece 7053 contacts the detection end of the second proximity switch 203, the slider 7051 can move upward relative to the trigger block 7, ensuring that no excessive pressure is applied to the detection end of the second proximity switch 203, preventing the proximity switch from being damaged due to overload, the slider 7051 is always located at the lowest part of the inner sliding cavity 704 by gravity (or a spring is arranged in the inner sliding cavity 704 to elastically support the top of the slider 7051), maintaining the stability of the signal triggering process.
[0067] The trigger block 7 protects the constant downward pressure of the second proximity switch 202 by the second trigger piece 705 in the descending process, and also needs to provide buffer protection during the upward process of the trigger block 7, so that the first trigger piece 703 on the trigger block 7 can contact the detection end of the first proximity switch 202 at a relatively slow speed, preventing the first trigger piece 703 from colliding with the detection end of the first proximity switch 202.
[0068] Among them, the inside of the connecting block 701 is provided with a closed upper cavity 7011 and a lower cavity 7012, the upper cavity 7011 and the lower cavity 7012 are communicated through a flow-through hole 7013, the diameter of the flow-through hole 7013 is smaller than the diameter of the upper cavity 7011 and the lower cavity 7012, the first piston 7014 is slidably connected in the upper cavity 7011, the top end of the first piston 7014 is provided with a top rod 7015 penetrating through the connecting block 701, the second piston 7016 is slidably connected in the lower cavity 7012, the lower cavity 7012 is provided with a spring 7017 for elastically supporting the bottom of the second piston 7016, the first piston 7014 and the second piston 7016 are filled with hydraulic oil, and the flow-through hole 7013 contacts the inner wall of the sliding groove 206 when the connecting block 701 rises.
[0069] Specifically, the closed cavity of the connecting block 701 is filled with hydraulic medium, when the cutter 6 rises rapidly to the top rod 7015 contacting the inner wall of the sliding groove 206, the top rod 7015 pushes the hydraulic oil in the upper cavity 7011 downward through the first piston 7014 and pushes it into the lower cavity 7012 through the flow-through hole 7013, so that the second piston 7016 slowly descends in the lower cavity 7012 and extrudes the spring 7017, the hydraulic resistance makes the top rod 7015 only slowly descend, so that the first trigger piece 703 contacts the detection end of the first proximity switch 20 at a slow speed, and this mechanism avoids the connecting block 701 from impacting the inner wall of the sliding groove 206 at high speed.
[0070] The second threaded hole 7018 is in threaded connection with a sealing bolt 7019, the sealing bolt 7019 rotates in the second threaded hole 7018 and extends into the flow hole 7013 to adjust the flow capacity of the flow hole 7013.
[0071] Specifically, if it is needed to adjust the speed of the upward buffering of the trigger block 7, the sealing bolt 7019 is continuously screwed into the second threaded hole 7018, the tapered end of the sealing bolt 7019 continuously inserts into the flow hole 7013, thereby continuously reducing the cross-sectional area of the flow hole 7013, forming an annular throttling gap; by adjusting the screwing depth of the sealing bolt, the effective flow area of the flow hole can realize linear change; the small flow capacity setting enhances the damping effect, and is used for emergency braking of high-speed operation of the cutter; the large flow capacity setting reduces the flow resistance, and meets the rapid circulation demand of continuous cutting of the thin plate.
[0072] Specifically, after receiving the instruction of the processor 204, the buzzer 207 triggers the intermittent short buzzing alarm according to the uncut event.
[0073] Specifically, after receiving the instruction of the processor 204, the buzzer 207 triggers the intermittent short buzzing alarm according to the uncut event.
[0074] Although the present application has been described in detail with general description and specific embodiments above, some modifications or improvements can be made on the basis of the present application, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not deviating from the spirit of the present application, all belong to the scope of the present application claimed.
