DETAILED DESCRIPTION

[0018] The following will be combined with 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.

[0019] Embodiment 1:

[0020] refer to Figure 1-9 A fully automatic cutting device for sponge production includes a frame 1, and the frame 1 includes a first bracket 101 and a second bracket 102. The first bracket 101 and the second bracket 102 are both provided with a conveying mechanism 2 for conveying sponge, and the two conveying mechanisms 2 are connected by a first synchronous belt pulley mechanism 103. The transmission ratio of the first synchronous belt pulley mechanism 103 in this embodiment is 1, which belongs to a uniform speed transmission mechanism. The first synchronous belt pulley mechanism 103 is a conventional synchronous belt pulley transmission, which belongs to the prior art known to those skilled in the art, and therefore will not be described in detail.

[0021] The gap between the first bracket 101 and the second bracket 102 forms a cutting space 104, and cutting mechanisms for cutting sponges are provided on both the upper and lower sides of the cutting space 104; The fixing mechanism is used to fix the sponge and fix the sponge first when the cutting mechanism cuts the sponge; The driving mechanism is used to drive the conveying mechanism 2 to move the sponge, and when the conveying mechanism 2 stops transporting, the driving mechanism can simultaneously drive the two cutting mechanisms to cut the sponge.

[0022] By setting up the conveying mechanism 2, the cutting mechanism, the fixing mechanism and the driving mechanism, the cutting device can achieve efficient coordinated work in cutting and conveying the sponge. When the conveying mechanism 2 stops transporting, the cutting action can be seamlessly connected, effectively avoiding the problem of asynchrony between sponge conveying and cutting, greatly improving the smoothness and accuracy of cutting, thereby significantly improving cutting efficiency and reducing operation time. The fixing mechanism can first fix the sponge when the cutting mechanism starts cutting, preventing it from moving or elastically deforming during the cutting process, improving cutting stability, and ensuring a smooth cutting surface of the sponge.

[0023] Specifically, the cutting mechanism includes a connecting plate 3 connecting the first bracket 101 and the second bracket 102, a support block 301 arranged on the top of the connecting plate 3, and a cutting knife 302 slidably connected to the support block 301, a sliding groove 303 is provided on the support block 301, and a guide rod 304 is fixedly connected inside the sliding groove 303, sliders 305 are provided on both sides of the cutting knife 302, the slider 305 is slidably connected to the guide rod 304, one end of the slider 305 extends to the outside of the support block 301, and the slider 305 is linked to the driving mechanism.

[0024] The cutting knife 302 is slidably connected to the guide rod 304 through the slider 305, thereby providing a stable and accurate motion trajectory. During the cutting process, the cutting knife 302 can accurately move along the predetermined trajectory of the guide rod 304, effectively reducing the cutting error caused by the shaking or offset of the tool, thereby improving the flatness of the cutting surface. The slider 305 is linked to the driving mechanism to facilitate the precise control of the automated cutting operation. In addition, the structural design is simple and modular, which is convenient for equipment maintenance and troubleshooting, and significantly reduces the difficulty and cost of maintenance.

[0025] Furthermore, there are two fixing mechanisms, and the two fixing mechanisms are respectively arranged on one side of the top of the first bracket 101 and the second bracket 102 close to the support block 301. The fixing mechanism includes a fixing plate 4, a support rod 401 arranged on both sides of the first bracket 101, a first elastic member 402 and a power component that causes the fixing plate 4 to compress the first elastic member 402. A receiving groove 403 is provided on both sides of the first bracket 101, the bottom of the support rod 401 is fixedly connected to the bottom of the receiving groove 403, the fixing plate 4 is slidably connected to the support rod 401, the first elastic member 402 is arranged between the fixing plate 4 and the bottom of the receiving groove 403, the horizontal height of the fixing plate 4 is lower than the horizontal height of the cutting knife 302, one end of the first elastic member 402 is fixedly connected to the bottom of the fixing plate 4, the other end of the first elastic member 402 is fixedly connected to the bottom of the receiving groove 403, and the first elastic member 402 is sleeved on the outer surface of the support rod 401. Sleeving the first elastic member 402 on the outer surface of the support rod 401 helps reduce the risk of the first elastic member 402 being offset or misaligned during long-term use, extends its service life, and ensures the reliability and stability of the fixing mechanism during long-term use.

[0026] Secondly, the two fixing mechanisms can fix the two ends of the sponge to prevent the sponge from being displaced or deformed due to uneven force during cutting, thereby further improving the cutting accuracy.

[0027] In this embodiment, the power assembly includes a traction rope 404, a winding wheel 405, racks 406 arranged on both sides of the slider 305, and a first gear 407 meshing with the rack 406. Both sides of the slide groove 303 are provided with a receiving groove 408. The first gear 407 is arranged inside the receiving groove 408 through a first rotating shaft 409 and is rotatably connected to the receiving groove 408. The winding wheel 405 is arranged on the first rotating shaft 409 and is fixedly connected to the first rotating shaft 409. One end of the traction rope 404 is fixedly connected to the fixed plate 4, and the other end of the traction rope 404 is fixedly connected to the winding wheel 405 through a plurality of pulleys 410.

[0028] The power assembly force in this embodiment utilizes the movement of the slider 305 to drive the rack 406, the gear and the winding wheel 405, thereby realizing the linkage between the movement of the cutting knife 302 and the fixed action of the fixed plate 4, reducing additional power sources and complex control systems, simplifying the equipment structure, reducing manufacturing costs and failure rates, and thus improving the reliability and stability of the equipment.

[0029] When the driving mechanism drives the cutting knife 302 to cut the sponge, the slider 305 moves downward under the action of the driving mechanism, thereby driving the rack 406 to move downward. The movement of the rack 406 drives the first gear 407 to rotate, thereby driving the first rotating shaft 409 to rotate, and the first rotating shaft 409 drives the winding wheel 405 to rotate, and the winding wheel 405 winds up one end of the traction rope 404 (when the cutting knife 302 cuts the sponge, one end of the rack 406 will move to the outside of the support block 301 under the action of the slider 305). The other end of the traction rope 404 pulls the fixing plate 4 to move in the direction of compressing the first elastic member 402. Since the horizontal height of the fixing plate 4 is lower than that of the cutting knife 302, the fixing plate 4 will first fix the two sides of the sponge to prevent the sponge from shifting during the cutting process.

[0030] After the cutting is completed, the reel 405 rotates in the opposite direction under the action of the rack 406, releasing the traction rope 404, and the first elastic member 402 drives the fixing plate 4 and the traction rope 404 to return to their original positions. This linkage mode makes the cutting and fixing actions closely coordinated, quickly completes the sponge fixing before the cutting starts, and releases it in time after the cutting is completed, thereby improving the coordination of the production rhythm and improving the overall production efficiency.

[0031] In this embodiment, the conveying mechanism 2 includes a first pulley 201 arranged on one side of the first bracket 101, a second pulley 202 arranged on the other side of the first bracket 101, a third pulley 203 arranged at the bottom of the first bracket 101, and a synchronous belt 204 for connecting the first pulley 201, the second pulley 202, and the third pulley 203. The conveying mechanism 2 on the second bracket 102 is the same.

[0032] The driving mechanism includes a fourth pulley 5 meshed with the synchronous belt 204, an incomplete gear 2 501 coaxially arranged with the fourth pulley 5, a second gear 502 arranged on the side of the first bracket 101 away from the second bracket 102, a rotating motor 503 for driving the fourth pulley 5 to rotate, and a rotating assembly for driving the two cutting knives 302 to move in opposite directions at the same time. The pulley teeth on the fourth pulley 5 are concentrated on one side of the fourth pulley 5 (one side of the fourth pulley 5 is provided with pulley teeth, while the other side is not provided with pulley teeth, and is arranged in half), the teeth of the incomplete gear 2 501 are concentrated on the side of the incomplete gear 2 501 away from the pulley teeth of the fourth pulley 5, and the incomplete gear 2 501 is meshed with the second gear 502, the second gear 502 is rotatably connected to the side of the first bracket 101 through the second rotating shaft 504, and the second gear 502 has the same specifications as the incomplete gear 2, except for the number of teeth.

[0033] More specifically, the rotating assembly includes a third gear 6 arranged on the second bracket 102, a connecting rod 601 rotatably connected to the second bracket 102 at one end, and a volute spring 602. Extension blocks 603 are provided on the upper and lower sides of the second bracket 102, and a accommodating space 604 is provided inside the extension block 603. The third gear 6 is rotatably connected to the inner wall of the accommodating space 604 through a third rotating shaft 605. The volute spring 602 is arranged inside the accommodating space 604, and one end of the third rotating shaft 605 is fixedly connected to the volute spring 602. The second rotating shaft 504 and the third rotating shaft 605 are connected through a second synchronous pulley mechanism 7 (the transmission ratio of the second synchronous pulley mechanism 7 in this embodiment is 1, which is a uniform speed transmission mechanism. The second synchronous pulley mechanism 7 is a conventional synchronous pulley transmission, which is a prior art known to those skilled in the art and is therefore not described in detail), and the third gears 6 in the two rotating assemblies are meshed with each other.

[0034] A sliding column 606 is connected to the side of the slider 305 away from the support block 301, a first sliding groove 607 is provided at the end of the connecting rod 601 close to the sliding column 606, the sliding column 606 is slidably connected to the inner wall of the first sliding groove 607, a sliding rod 608 is provided at the top of the side of the third gear 6 away from the extension block 603, a second sliding groove 609 is provided on the side of the connecting rod 601 close to the sliding rod 608, the sliding rod 608 is slidably connected to the inner wall of the second sliding groove 609.

[0035] When in use, the staff drives the output end of the rotating motor 503 to rotate clockwise, and the output end of the rotating motor 503 will simultaneously drive the fourth pulley 5 and the second incomplete gear 501 to rotate clockwise. When the output end of the rotating motor 503 rotates half a circle, the pulley teeth on the fourth pulley 5 first drive the synchronous belt 204 on the first bracket 101 to move, and at the same time, the synchronous belt 204 on the first bracket 101 drives the conveying mechanism 2 on the second bracket 102 to move through the first synchronous pulley mechanism 103, thereby transporting the sponge on the synchronous belt 204.

[0036] When the output end of the rotating motor 503 rotates from half a circle to one circle, the pulley teeth on the fourth pulley 5 cannot mesh with the synchronous belt 204, causing the synchronous belt 204 to stop transporting. However, the incomplete gear 2 501 is provided with gear teeth on the side away from the pulley teeth, so the gear teeth on the incomplete gear 2 501 will mesh with the second gear 502, thereby driving the second gear 502 to rotate half a circle counterclockwise. The second gear 502 drives the second rotating shaft 504 to rotate half a circle counterclockwise, and the second rotating shaft 504 drives the third rotating shaft 605 to rotate half a circle through the second synchronous pulley mechanism 7. The third rotating shaft 605 drives the third gear 6 to rotate half a circle counterclockwise, and the rotation of the third gear 6 causes the volute spring 602 to retract. Then, the sliding rod 608 on the third gear 6 drives the connecting rod 601 to rotate counterclockwise, and the sliding rod 608 slides in the second sliding groove 609, and the other end of the connecting rod 601 drives the sliding column 606 to move downward. Since the guide rod 304 limits the freedom of the slider 305 , the sliding column 606 drives the slider 305 to move downward along the axis direction of the guide rod 304 , thereby driving the cutting knife 302 to cut the sponge. At the same time, the sliding column 606 slides in the first sliding groove 607 .

[0037] When the output end of the rotating motor 503 rotates from one circle to one and a half circles, since there is no gear tooth on the other side of the incomplete gear 2 501, the incomplete gear 2 501 cannot drive the second gear 502 to rotate, and the volute spring 602 is quickly relaxed, driving the third rotating shaft 605 to rotate clockwise. The third rotating shaft 605 drives the third gear 6 to rotate clockwise, and the sliding rod 608 on the third gear 6 drives the connecting rod 601 and the sliding column 606 to return to their original positions.

[0038] In this embodiment, through the cooperation of the incomplete second gear 502 and the power component, precise switching and coordination of the conveying and cutting actions are achieved. Through the drive of the rotating motor 503, the cutting mechanism can be accurately started at the moment the conveying stops, reducing mechanical action delays and energy losses, making the production process more efficient and energy-saving.

[0039] The purpose of setting the third pulley 203 in the conveying mechanism 2 in this embodiment is to provide sufficient space between the upper and lower synchronous belts 204 so that the staff can replace the fourth pulley 5 of different sizes, thereby controlling the length of the cut sponge according to actual needs, thereby improving the applicability of the equipment.

[0040] Furthermore, one end of the connecting rod 601 away from the sliding column 606 is fixedly connected with a fourth gear 610, and the fourth gear 610 is rotatably connected to the side of the second bracket 102 through a fourth rotating shaft 611, and the fourth gears 610 on the connecting rods 601 in the two rotating components are meshed with each other. By setting the fourth gear 610, when the third gear 6 drives the sliding rod 608 to rotate, the connecting rod 601 can synchronously drive the other group of connecting rods 601 to rotate. It can effectively reduce the torque required for the sliding column 606 to drive the connecting rod 601 and the cutting knife 302 to move, and at the same time reduce the load of the connecting rod 601, thereby increasing the service life of the power component and ensuring the stability and reliability of the driving mechanism during long-term use.

[0041] In this embodiment, the sliding column 606 and the sliding rod 608 are both cylindrical in structure, and the sliding column 606 and the sliding rod 608 are rotatably connected to the slider 305 and the third gear 6 respectively. The cylindrical sliding column 606 and the sliding rod 608 can reduce the contact area with the first sliding groove 607 and the second sliding groove 609, thereby reducing the resistance when the sliding column 606 or the sliding rod 608 moves, making the movement between the components smoother, and improving the operating efficiency and reliability of the equipment. At the same time, the sliding column 606 and the sliding rod 608 are rotatably connected to the slider 305 and the third gear 6 respectively because the force received by dynamic friction is smaller than that received by static friction. Therefore, by rotatably connecting the sliding column 606 and the sliding rod 608, the resistance generated by them during movement can be further reduced.

[0042] Working principle: When in use, the staff drives the output end of the rotating motor 503 to rotate clockwise, and the output end of the rotating motor 503 will simultaneously drive the fourth pulley 5 and the second incomplete gear 501 to rotate clockwise. When the output end of the rotating motor 503 rotates half a circle, the pulley teeth on the fourth pulley 5 first drive the synchronous belt 204 on the first bracket 101 to move, and at the same time, the synchronous belt 204 on the first bracket 101 drives the conveying mechanism 2 on the second bracket 102 to move through the first synchronous pulley mechanism 103, thereby transporting the sponge on the synchronous belt 204.

[0043] When the output end of the rotating motor 503 rotates from half a circle to one circle, the pulley teeth on the fourth pulley 5 cannot mesh with the synchronous belt 204, causing the synchronous belt 204 to stop transporting. However, the incomplete gear 2 501 is provided with gear teeth on the side away from the pulley teeth, so the gear teeth on the incomplete gear 2 501 will mesh with the second gear 502, thereby driving the second gear 502 to rotate half a circle counterclockwise. The second gear 502 drives the second rotating shaft 504 to rotate half a circle counterclockwise, and the second rotating shaft 504 drives the third rotating shaft 605 to rotate half a circle through the second synchronous pulley mechanism 7. The third rotating shaft 605 drives the third gear 6 to rotate half a circle counterclockwise, and the rotation of the third gear 6 causes the volute spring 602 to retract. Then, the sliding rod 608 on the third gear 6 drives the connecting rod 601 to rotate counterclockwise, and the sliding rod 608 slides in the second sliding groove 609, and the other end of the connecting rod 601 drives the sliding column 606 to move downward. Since the guide rod 304 limits the freedom of the slider 305 , the sliding column 606 drives the slider 305 to move downward along the axis direction of the guide rod 304 , thereby driving the cutting knife 302 to cut the sponge. At the same time, the sliding column 606 slides in the first sliding groove 607 .

[0044] When the slider 305 moves downward under the action of the driving mechanism, it drives the rack 406 to move downward. The movement of the rack 406 drives the first gear 407 to rotate, which in turn drives the first rotating shaft 409 to rotate, and the first rotating shaft 409 drives the winding wheel 405 to rotate. The winding wheel 405 winds up one end of the traction rope 404, and the other end of the traction rope 404 pulls the fixing plate 4 to move in the direction of compressing the first elastic member 402. Since the horizontal height of the fixing plate 4 is lower than the cutting knife 302, the fixing plate 4 will first fix the two sides of the sponge to prevent the sponge from shifting during the cutting process.

[0045] When the output end of the rotating motor 503 rotates from one circle to one and a half circles, since there is no gear tooth on the other side of the incomplete gear 2 501, the incomplete gear 2 501 cannot drive the second gear 502 to rotate, and the volute spring 602 is quickly relaxed, driving the third rotating shaft 605 to rotate clockwise. The third rotating shaft 605 drives the third gear 6 to rotate clockwise, and the sliding rod 608 on the third gear 6 drives the connecting rod 601 and the sliding column 606 to return to their original positions. The connecting rod 601 will drive the sliding column 606 to move upward, and at the same time the sliding column 606 will drive the slider 305 to move upward, the slider 305 will synchronously drive the rack 406 to move, and the winding wheel 405 will rotate in the opposite direction under the action of the rack 406 to release the traction rope 404, and the first elastic member 402 will drive the fixed plate 4 and the traction rope 404 to return to their original positions (it is worth noting that in order to ensure that the fixed plate 4 can be separated from the sponge surface when the conveying mechanism 2 conveys the sponge, the number of teeth on the gear of the fourth pulley 5 can be reduced so that it appears in neutral when switching, thereby driving the fixed plate 4 to separate from the sponge surface through the first elastic member 402).

[0046] Embodiment 2:

[0047] Based on Example 1, refer to Fig.10 In this embodiment, a squeezing plate 801 is connected to the bottom of the fixed plate 4 through a plurality of second elastic members 8 (the second elastic member 8 can be a cylindrical compression spring). When the fixed plate 4 moves downward under the action of the traction rope 404, the squeezing plate 801 will first contact the surface of the sponge and fix the sponge. The purpose of setting the second elastic member 8 is to allow a certain movable space to be maintained between the fixed plate 4 and the squeezing plate 801, so as to avoid excessive compression of the sponge by the fixed plate 4.

[0048] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
