Description

Technical Field

[0001] This utility model relates to the field of sponge cutting technology, specifically a monitoring alarm protection device for a sponge cutting machine. Background Technology

[0002] A sponge is a porous, elastic material, typically made of wood cellulose fibers or foamed plastic polymers. It has excellent water absorption and is commonly used for cleaning items. During production and processing, sponges need to be cut into the required size and shape according to their intended use.

[0003] Sponge cutting requires a sponge cutting machine, which offers advantages such as high precision, high efficiency, ease of operation, and durability. The open work platform facilitates material placement and can be integrated into production lines to handle large-format materials.

[0004] For example, a laser cutting machine alarm device with application number 202122061732.X has detection heads set at multiple ends of a cross-shaped block, which can detect the laser cutter from multiple directions, thus enabling comprehensive detection. However, this device still has certain shortcomings.

[0005] When cutting sponges, the cutting location cannot be shielded or warned, allowing nearby workers to put their hands or other limbs near the cutting head without any warning, posing a significant safety hazard.

[0006] Therefore, we propose a monitoring and alarm protection device for sponge cutting machines to solve the problems mentioned above. Utility Model Content

[0007] The purpose of this utility model is to provide a monitoring and alarm protection device for a sponge cutting machine, in order to solve the problem mentioned in the background art that the current market cannot block and remind the cutting position when cutting sponges, so that the workers next to the machine can put their hands or other limbs near the cutting head when the machine is cutting, without any warning effect, thus posing a great safety hazard.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a monitoring alarm protection device for a sponge cutting machine, including a cutting table, a support frame installed above the cutting table, an alarm light installed above the support frame, and rectangular blocks installed on both the left and right sides of the support frame;

[0009] Protective strips are installed on the front surfaces of both sides of the support frame via rotating shaft assemblies. Electromagnets are installed on both sides of the support frame. An arc-shaped groove is opened on the right side of the rectangular block on the left side. A mounting platform is installed on the right side of the rectangular block on the left side, and a forward and reverse motor is installed on the right side of the mounting platform. A transmission shaft is installed on the left side of the forward and reverse motor via an output shaft. The transmission shaft is connected to the slider via a connecting strip. An infrared sensor is installed on the slider.

[0010] Preferably, a cutting control mechanism is installed on the support frame, and a sponge cutting head is installed below the cutting control mechanism. The cutting control mechanism can control the direction of the sponge cutting head.

[0011] With the above structural design, the cutting control mechanism can adjust the position of the sponge cutting head, making it convenient to cut different positions of the sponge. The cutting control mechanism is existing technology in this field, and its internal structure will not be described in detail here.

[0012] Preferably, a fixing block is installed on each opposite side of the rectangular block, and a support plate is installed above the fixing block by means of a shock-absorbing spring and a damper.

[0013] With the above structural design, when the electromagnet is de-energized, the protective strip rotates relative to the rotating shaft assembly under the action of the counterweight and gravity, so that the protective strip abuts against the support plate. Under the action of the shock-absorbing spring and damper, the support plate can reduce the impact force of the protective strip and make the protective strip less prone to damage.

[0014] Preferably, there are two damping springs, and the damping springs are located on the left and right sides of the damper, with the support plate located on the rectangular block near the bottom.

[0015] By adopting the above structural design, the support plate improves its shock absorption effect when subjected to the impact force of the protective strip.

[0016] Preferably, the protective strip is rotatably connected to the rotating shaft assembly, a warning light strip is installed on the front surface of the protective strip, and a counterweight is installed on the side of the protective strip.

[0017] With the above structural design, when the protective strip is in a horizontal state, the warning light strip on the protective strip can serve as a warning to remind staff not to put their hands near it.

[0018] Preferably, when the protective strip is rotated upwards to a vertical position, the electromagnet abuts against the side of the protective strip. At this time, the electromagnet is energized and can attract and fix the protective strip. The electromagnet is connected to the control button of the forward and reverse motor. When the electromagnet is energized, the output shaft of the forward and reverse motor rotates clockwise. When the electromagnet is de-energized, the output shaft of the forward and reverse motor rotates counterclockwise.

[0019] With the above structural design, when the electromagnet is de-energized, the output shaft of the forward and reverse motors rotates counterclockwise. The forward and reverse motors drive the transmission shaft to rotate counterclockwise, and the transmission shaft drives the slider to slide along the arc-shaped groove through the connecting strip, moving the slider to a position near the front of the rectangular block. This positions the infrared sensor near the front of the rectangular block. When a worker approaches the infrared sensor, the infrared sensor transmits a signal to the controller, which then activates the alarm light, serving as a second warning. When the electromagnet is energized, the output shaft of the forward and reverse motors rotates clockwise, similarly moving the slider to a position near the rear of the rectangular block. This positions the infrared sensor near the rear of the rectangular block, preventing the infrared sensor from triggering an alarm when workers place the sponge.

[0020] Preferably, the slider is located in the arc-shaped groove and is slidably connected to the arc-shaped groove. The infrared sensor is connected to the controller, and the controller is connected to the alarm light.

[0021] With the above structural design, the slider can slide along the arc groove when subjected to force, thus making the slider more stable when sliding.

[0022] Compared with the prior art, the beneficial effects of this utility model are: the sponge cutting machine uses a monitoring alarm protection device:

[0023] 1. Equipped with shock-absorbing springs and dampers, when the electromagnet is de-energized, the protective strip rotates relative to the rotating shaft assembly under the action of the counterweight and gravity, causing the protective strip to abut against the support plate. Under the action of the shock-absorbing springs and dampers, the support plate can reduce the impact force of the protective strip, making the protective strip less prone to damage.

[0024] 2. A warning light strip is installed. When the protective strip is in a horizontal position, the warning light strip on the protective strip can serve as a warning to remind staff not to put their hands near it.

[0025] 3. Equipped with an electromagnet, a forward / reverse motor, and an infrared sensor, when the electromagnet is de-energized, the output shaft of the forward / reverse motor rotates counterclockwise. The motor drives the transmission shaft to rotate counterclockwise, and the transmission shaft, through a connecting strip, moves the slider along the arc-shaped groove, placing it on the rectangular block near the front. This positions the infrared sensor on the rectangular block near the front. When a worker approaches the infrared sensor, it transmits a signal to the controller, which then activates the alarm light, serving as a secondary warning. When the electromagnet is energized, the output shaft of the forward / reverse motor rotates clockwise, similarly moving the slider to the rectangular block near the rear. This positions the infrared sensor on the rectangular block near the rear, preventing the infrared sensor from triggering an alarm when workers place the sponge. Attached Figure Description

[0033] 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.

[0034] Please see Figures 1-6This utility model provides a technical solution: a monitoring and alarm protection device for a sponge cutting machine, including a cutting table 1, a support frame 2, a cutting control mechanism 3, a sponge cutting head 4, an alarm light 5, a rectangular block 6, a fixing block 7, a shock-absorbing spring 8, a damper 9, a support plate 10, a rotating shaft assembly 11, a protective strip 12, a warning light strip 13, a counterweight 14, an electromagnet 15, an arc groove 16, a mounting platform 17, a forward and reverse motor 18, a transmission shaft 19, a connecting strip 20, a slider 21, and an infrared sensor 22. The support frame 2 is mounted above the cutting table 1, and the cutting control mechanism 3 is mounted on the support frame 2. The sponge cutting head 4 is mounted below the cutting control mechanism 3. The cutting control mechanism 3 can control the direction of the sponge cutting head 4 and adjust the position of the sponge cutting head 4 to facilitate cutting at different positions of the sponge. Mechanism 3 is existing technology in this field, and its internal structure will not be described in detail here. An alarm light 5 is installed above the support frame 2. Rectangular blocks 6 are installed on both the left and right sides of the support frame 2. Fixing blocks 7 are installed on the opposite side of the rectangular blocks 6. A support plate 10 is installed above the fixing blocks 7 via shock-absorbing springs 8 and dampers 9. When the electromagnet 15 is de-energized, the protective strip 12 rotates relative to the rotating shaft assembly 11 under the action of the counterweight 14 and gravity, so that the protective strip 12 abuts against the support plate 10. Under the action of shock-absorbing springs 8 and dampers 9, the support plate 10 can reduce the impact force of the protective strip 12, making the protective strip 12 less prone to damage. There are two shock-absorbing springs 8, and the shock-absorbing springs 8 are located on the left and right sides of the dampers 9. The support plate 10 is located on the rectangular blocks 6 near the bottom. When the support plate 10 is subjected to the impact force of the protective strip 12, the shock absorption effect of the support plate 10 is improved.

[0035] Protective strips 12 are mounted on the left and right sides of the support frame 2 via rotating shaft assemblies 11. The protective strips 12 are rotatably connected to the rotating shaft assemblies 11. Warning light strips 13 are mounted on the front surface of the protective strips 12, and counterweights 14 are mounted on the sides of the protective strips 12. When the protective strips 12 are horizontal, the warning light strips 13 on the protective strips 12 serve as a warning, reminding workers not to bring their hands near them. Electromagnets 15 are mounted on both the left and right sides of the support frame 2. When the protective strips 12 are rotated upwards to a vertical position, the electromagnets 15 abut against the sides of the protective strips 12, at which point the electromagnets 15 are activated. The protective strip 12 is attracted and fixed by electricity. The control buttons of the electromagnet 15 and the forward / reverse motor 18 are connected. When the electromagnet 15 is energized, the output shaft of the forward / reverse motor 18 rotates clockwise. When the electromagnet 15 is de-energized, the output shaft of the forward / reverse motor 18 rotates counterclockwise. The forward / reverse motor 18 drives the transmission shaft 19 to rotate counterclockwise. The transmission shaft 19 drives the slider 21 to slide along the arc groove 16 through the connecting strip 20, moving the slider 21 to a position near the front of the rectangular block 6, thereby placing the infrared sensor 22 in the rectangular block. On block 6, near the front, when a worker approaches the infrared sensor 22, the sensor transmits a signal to the controller, which then activates alarm light 5, serving as a secondary warning. When electromagnet 15 is energized, the output shaft of the forward / reverse motor 18 rotates clockwise, similarly moving slider 21 to a position near the rear on rectangular block 6. This positions the infrared sensor 22 near the rear on rectangular block 6, preventing the sensor from triggering an alarm when workers place the sponge. An arc-shaped groove 16 is located on the right side of the left rectangular block 6. A mounting platform 17 is installed on the right side of the rectangular block 6, and a forward / reverse motor 18 is installed on the right side of the mounting platform 17. A transmission shaft 19 is installed on the left side of the forward / reverse motor 18 via an output shaft. The transmission shaft 19 is connected to the slider 21 via a connecting strip 20. An infrared sensor 22 is installed on the slider 21. The slider 21 is located in the arc groove 16 and is slidably connected to the arc groove 16. The infrared sensor 22 is connected to the controller, and the controller is connected to the alarm light 5. When the slider 21 is subjected to force, it can slide along the arc groove 16, thereby making the slider 21 more stable when sliding.

[0036] Working Principle: When using the monitoring and alarm protection device for this sponge cutting machine, firstly, the electromagnet 15 is energized, and the output shaft of the forward and reverse motor 18 rotates clockwise, moving the slider 21 to a position near the rear of the rectangular block 6. This positions the infrared sensor 22 near the rear of the rectangular block 6, preventing the infrared sensor 22 from triggering an alarm when the worker places the sponge. Then, the protective strip 12 is rotated to a vertical position, attracting and fixing the electromagnet 15. The sponge is then placed on the cutting table 1. Finally, the electromagnet 15 is de-energized, and the forward and reverse motors... The output shaft 18 rotates counterclockwise, driving the transmission shaft 19 to rotate counterclockwise. The transmission shaft 19, via the connecting strip 20, drives the slider 21 to slide along the arc-shaped groove 16, moving the slider 21 to a position near the front of the rectangular block 6. This positions the infrared sensor 22 near the front of the rectangular block 6. The cutting control mechanism 3 controls the sponge cutting head 4 to cut the sponge. When a worker approaches the infrared sensor 22, the sensor transmits a signal to the controller, which activates the alarm light 5, serving as a secondary warning. This completes a series of operations. Content not described in detail in this specification is prior art known to those skilled in the art.
