Description

Technical Field

[0001] This utility model relates to the field of wood strip cutting control technology, specifically a wood strip cutting control device for a slitting machine. Background Technology

[0002] As a core piece of equipment for slitting metal, sheet, and strip materials, slitting machines often face the problem of strip jamming during the cutting process. When the blades cut the strip, the strip easily becomes embedded in the blade gap and is difficult to eject, not only interrupting the slitting process but also easily causing quality defects such as excessive burrs on the cut edge and deviations in straightness. To alleviate this problem, the industry generally uses fixed wooden strips to press down on the strip, using the pushing force of the wooden strips to help the strip detach from the blades.

[0003] However, traditional fixed wooden strip devices have significant limitations: the downward pressure cannot be dynamically adjusted, and the adaptability is extremely poor. When encountering thinner strips, the fixing pressure can easily cause the strips to bend and deform under pressure, affecting the accuracy of subsequent processing. When encountering thicker strips, the thrust is insufficient to push out the stuck strips, and the machine still frequently stops due to tool jamming. Utility Model Content

[0004] The purpose of this invention is to provide a control device for cutting wood strips in a slitting machine, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a slitting machine cutting wood strip control device, comprising: a mounting plate disposed above the cutter shaft, and further comprising: multiple equidistant sliding openings formed on the top outer wall of the mounting plate, a pressure sensor installed on one inner wall of one sliding opening, and a support assembly installed on the other inner wall of the sliding opening, multiple equidistant wood strip assemblies rotatably mounted on the bottom outer wall of the mounting plate, a connecting plate installed at one end of the top outer wall of the mounting plate, a controller installed on the top outer wall of the connecting plate, and multiple equidistant pressing assemblies installed on the bottom outer wall of the connecting plate, a mounting frame installed on the top outer wall of the mounting plate, and telescopic assemblies installed at both ends of the top outer wall of the mounting frame, with the same fixed plate installed on the top of the two telescopic assemblies.

[0006] The support assembly includes a sliding rod, a spring sleeved on the outside of the sliding rod, a slider sleeved on the outside of the sliding rod, and an arc-shaped plate mounted on the top of the slider.

[0007] The wood strip assembly includes a wood strip and a traction rod rotatably mounted on the outer wall of one side of the wood strip.

[0008] The top end of the traction rod is rotatably connected to the bottom outer wall of the slider.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-6The slitting control device for a longitudinal shearing machine provided by this utility model includes: a mounting plate 2 located above the cutter shaft 1; multiple equidistant sliding openings 3 opened on the top outer wall of the mounting plate 2; a pressure sensor 4 installed on one inner wall of one side of the sliding opening 3; a support component 5 installed on the other inner wall of the sliding opening 3; multiple equidistant wood strip components 6 rotatably mounted on the bottom outer wall of the mounting plate 2; a connecting plate 7 installed at one end of the top outer wall of the mounting plate 2; a controller 8 installed on the top outer wall of the connecting plate 7; multiple equidistant pressing components 9 installed on the bottom outer wall of the connecting plate 7; a mounting frame 10 installed on the top outer wall of the mounting plate 2; and telescopic components 11 installed at both ends of the top outer wall of the mounting frame 10. The same fixed plate 12 is installed on the top of the two telescopic components 11.

[0016] It should be noted here that: Basic anti-jamming function: When the slitting machine cuts the strip 13 through the blade of the cutter shaft 1, the wooden strip assembly 6 at the bottom of the mounting plate 2 acts directly on the reverse side of the strip 13 to push out the strip 13 that may be stuck in the blade, avoiding jamming that affects the continuity of cutting and the quality of the cut edge. Thin strip protection mechanism: The support component 5 inside the sliding opening 3 of the mounting plate 2 provides elastic support to the wood strip assembly 6. When cutting thinner strip 13, the elastic buffer of the support component 5 can prevent the wood strip assembly 6 from being under too much pressure and causing the strip 13 to bend. Thick strip pressure adjustment mechanism: When cutting a thicker strip 13, the original downward pressure of the wood strip assembly 6 is insufficient, and it will be pushed upward by the strip 13, thereby driving the support assembly 5 to move within the sliding port 3 and touch the pressure sensor 4; the pressure sensor 4 transmits the "pressure trigger signal" to the controller 8 on the connecting plate 7, and the controller 8 immediately controls the corresponding pressing assembly 9 at the bottom of the connecting plate 7 to descend; the pressing assembly 9 pushes the support assembly 5 to move, thereby driving the wood strip assembly 6 to rotate, causing the bottom of the wood strip assembly 6 to descend, increasing the downward pressure on the thick strip 13, and ensuring that the thick strip 13 can be smoothly pushed out; Device compatibility guarantee: The mounting bracket 10 on the mounting plate 2 and the telescopic components 11 at both ends can adjust the height of the top fixed plate 12, making it easy to adjust the installation height.

[0017] In a preferred embodiment, the support assembly 5 includes a sliding rod 501, a spring 502 sleeved on the outside of the sliding rod 501, a slider 503 sleeved on the outside of the sliding rod 501, and an arc-shaped plate 504 mounted on the top of the slider 503.

[0018] It should be noted here that: the sliding rod 501 is fixed to the inner wall on the other side of the sliding opening 3, the spring 502 is sleeved on the outside of the sliding rod 501 and connected to the slider 503, and the slider 503 can slide along the sliding rod 501; when the wood strip assembly 6 is pushed upward by the reaction force of the strip 13, it will drive the slider 503 to move along the sliding rod 501 towards the pressure sensor 4. At this time, the spring 502 is stretched (or compressed), and the elastic force of the spring 502 offsets part of the reaction force, so as to avoid the wood strip assembly 6 applying too much pressure to the thin strip 13; The arc-shaped plate 504 at the top of the slider 503 can adapt to the pressure of the pressing component 9, while the bottom of the slider 503 is connected to the wooden strip component 6. When the slider 503 is pushed by the strip 13 to contact the pressure sensor 4, the "pressure trigger signal" is directly transmitted to the controller 8 through the pressure sensor 4. When the pressing component 9 descends, it will first act on the arc-shaped plate 504, and then push the slider 503 along the sliding rod 501 through the arc-shaped plate 504 to ensure the uniform transmission of force.

[0019] In a preferred embodiment, the wood strip assembly 6 includes a wood strip 601 and a traction rod 602 rotatably mounted on one side of the outer wall of the wood strip 601; the top end of the traction rod 602 is rotatably connected to the bottom outer wall of the slider 503.

[0020] It should be noted that: the wood strip 601 in the wood strip assembly 6 is rotatably mounted on the bottom outer wall of the mounting plate 2, and its bottom is in direct contact with the strip 13; when the blade of the slitting machine cutter shaft 1 jams the strip 13, the wood strip 601, supported by its own mounting position, can push the strip 13 out of the blade, preventing the strip 13 from jamming and affecting the continuity of slitting or the quality of the cut edge; the traction rod 602 is rotatably mounted on one side of the outer wall of the wood strip 601, and its top is rotatably connected to the support assembly 5, which plays a role in force transmission - when the thickness of the strip 13 changes, the reaction force of the strip 13 on the wood strip 601 will be transmitted to the support assembly 5 through the traction rod 602. For example, when the thick strip 13 pushes up the wood strip 601, the wood strip 601 drives the traction rod 602 to move upward, and the traction rod 602 then pulls the support assembly 5 to move towards the pressure sensor 4, triggering pressure detection and subsequent pressurization action.

[0021] In a preferred embodiment, the pressing assembly 9 includes an electric push rod 901 and a pressure block 902 mounted on the bottom of the piston rod of the electric push rod 901.

[0022] It should be noted that when the pressing component 9 does not receive an action signal, the piston rod of the electric push rod 901 is in a retracted state, and the pressing block 902 is away from the support component 5. When the thick strip 13 pushes up the wood strip component 6, causing the support component 5 to touch the pressure sensor 4, the pressure sensor 4 transmits a signal to the controller 8, and the controller 8 sends an action command to the corresponding electric push rod 901. After receiving the command, the piston rod of the electric push rod 901 extends downward, causing the pressing block 902 at the bottom to descend synchronously. After the pressing block 902 descends, it contacts the support component 5 (the arc plate 504 at the top of the slider 503) and applies a downward thrust to the support component 5, pushing the slider 503 to move away from the pressure sensor 4 along the sliding rod 501. When the slider 503 moves, it drives the wood strip plate 601 to rotate around the bottom of the mounting plate 2 through the traction rod 602, so that the bottom of the wood strip plate 601 moves closer to the strip 13, increasing the downward pressure on the strip 13 and ensuring that the thick strip 13 can be successfully ejected from the blade.

[0023] In a preferred embodiment, the telescopic assembly 11 includes a square tube 1101, a movable rod 1102 slidably connected to the inner wall of the square tube 1101, first through holes opened on the outer walls of both sides of the square tube 1101, a plurality of second through holes equally distributed on one side of the outer wall of the movable rod 1102, and a fixing pin 1103 adapted to the through holes.

[0024] It should be noted that: the square tube 1101 in the telescopic assembly 11 is fixed to the top outer wall of the mounting bracket 10, and the movable rod 1102 is slidably connected to the inner wall of the square tube 1101, and can slide up and down along the square tube 1101; when it is necessary to adjust the height of the fixing plate 12 to adapt to the installation height of different cutter shafts 1 or the thickness of the strip 13, first pull out the fixing pin 1103 that passes through the first through hole of the square tube 1101 and the second through hole of the movable rod 1102, and then push the movable rod 1102 to slide inside the square tube 1101 until the fixing plate 12 reaches the required height; at this time, observe the first through hole of the square tube 1101 and the second through hole on the movable rod 1102. When the two are aligned, re-insert the fixing pin 1103 into the aligned through hole to fix the relative position of the square tube 1101 and the movable rod 1102, thereby fixing the overall length of the telescopic assembly 11.

[0025] Working principle: Basic ejection and elastic buffering stage: The wooden strip assembly 6 (including wooden strip 601 and traction rod 602) installed on the bottom outer wall of the mounting plate 2 directly contacts the strip 13, which can eject the strip 13 stuck in the blade of the cutter shaft 1; at the same time, the support assembly 5 (composed of sliding rod 501, spring 502, slider 503 and arc plate 504) in the sliding port 3 at the top of the mounting plate 2 provides elastic support for the wooden strip assembly 6. The slider 503 is sleeved on the outside of the sliding rod 501, and the spring 502 is also sleeved on the sliding rod 501 and connected to the slider 503. When encountering a thinner strip 13, the spring 502 can buffer the force movement of the slider 503, and then reduce the pressure of the wooden strip 601 on the strip 13 through the traction rod 602 adapted to the bottom of the slider 503, so as to prevent the strip 13 from being bent.

[0026] Pressure detection and pressurization adjustment stage: If a thicker strip 13 is encountered, the strip 13 will push the wooden strip plate 601 of the wooden strip assembly 6 upwards. After the wooden strip plate 601 is subjected to force, it will drive the traction rod 602 on one side to move upwards. Because the top of the traction rod 602 is adapted to the bottom of the slider 503, the traction rod 602 will pull the slider 503 to slide along the sliding rod 501 towards the pressure sensor 4 on the side of the sliding port 3, until the slider 503 (or its top arc plate 504) touches the pressure sensor 4. The pressure sensor 4 will transmit the trigger signal to the controller 8 installed on the top of the connecting plate 7 (the connecting plate 7 is fixed on the controller 8). After receiving the signal, the controller 8 controls the corresponding pressing component 9 (including electric push rod 901 and pressure block 902) at the bottom of the connecting plate 7 to move. The piston rod of the electric push rod 901 extends downward, causing the pressure block 902 at the bottom to descend. The pressure block 902 contacts the arc plate 504 and pushes the slider 503 to move in the opposite direction along the sliding rod 501. When the slider 503 moves, it drives the wooden strip 601 to rotate around the bottom of the mounting plate 2 through the traction rod 602, so that the bottom of the wooden strip 601 moves closer to the strip 13, increasing the downward pressure on the strip 13 and ensuring that the thick strip 13 can be smoothly ejected from the blade.

[0027] Device height adaptation stage: Both ends of the mounting bracket 10 on the top outer wall of the mounting plate 2 are equipped with telescopic components 11 (composed of square tube 1101, movable rod 1102, and fixed pin 1103). The tops of the two telescopic components 11 are connected to the same fixed plate 12. When it is necessary to adapt to different tool shaft 1 heights or strip (13) processing scenarios, pull out the fixed pin 1103 that passes through the first through hole of square tube 1101 and the second through hole of movable rod 1102, push the movable rod 1102 to slide on the inner wall of square tube 1101 to adjust the overall length of the telescopic component 11. After the fixed plate 12 reaches the required height, re-insert the fixed pin 1103 into the aligned through hole for fixation.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
