Description

Technical Field

[0001] This utility model relates to the field of composite nonwoven fabric processing technology, and in particular to a device for uniformly cutting anti-displacement, antibacterial flash evaporation composite nonwoven fabric. Background Technology

[0002] Composite nonwoven fabric is a new type of material that is made by bonding two or more materials together through chemical or physical methods. In the processing of composite nonwoven fabric, it is necessary to cut the nonwoven fabric evenly. Traditional uniform cutting devices have difficulty limiting the displacement of the nonwoven fabric under compression during the cutting process. In other words, when the cutting equipment is cutting, the cutter will compress the stacked layers of nonwoven fabric, and the upper layers of nonwoven fabric will be displaced in turn. This causes errors in the subsequent cutting of nonwoven fabric, resulting in different dimensions of nonwoven fabric cut from different layers, which is difficult to meet the usage requirements, and will also lead to waste of material costs and affect the subsequent use of nonwoven fabric.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0004] This invention proposes a device for uniformly cutting anti-displacement, antibacterial flash evaporation composite nonwoven fabric, which solves the above-mentioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows: a device for uniformly cutting anti-displacement, antibacterial flash evaporation composite nonwoven fabric includes a gantry frame. A cutter is slidably installed inside the gantry frame. Both ends of one side of the cutter are fixedly connected to limiting sliders that slide inside the gantry frame. A mounting frame is detachably installed on one side of the two limiting sliders. Sliding screws are provided through the top two sides of the mounting frame. Pressure blocks are fixedly connected to the bottom ends of the two sliding screws. Springs are sleeved on the surface of the sliding screws. The two ends of the springs are fixedly connected to the mounting frame and the pressure blocks, respectively. Adjusting nuts adapted to the mounting frame are threaded on the surface of the sliding screws. A rubber strip is detachably installed on the bottom of the pressure block.

[0006] The present invention, as described above, is a device for uniformly cutting anti-displacement, antibacterial flash evaporation composite nonwoven fabric. Further, the bottom of the pressure block is provided with a groove adapted to the rubber strip, and a connecting bolt is provided through the bottom of the rubber strip. The rubber strip is fixedly installed on the pressure block by the connecting bolt.

[0007] The present invention, as described above, is a device for uniformly cutting anti-displacement, antibacterial flash-evaporation composite nonwoven fabric. Further, an electric push rod is fixedly installed on the top of the gantry frame, and the output end of the electric push rod extends through the interior of the gantry frame and is fixedly installed on the top of the cutter.

[0008] The present invention further comprises the following: a workbench is fixedly installed at the bottom of the gantry frame, and two limiting grooves adapted to the limiting slider are provided on one side of the gantry frame.

[0009] The present invention further comprises the following: a baffle is fixedly installed on one side of the workbench.

[0010] The present invention, as described above, is a device for uniformly cutting anti-displacement, antibacterial flash-evaporation composite nonwoven fabric. Further, four fixing blocks are fixedly connected to the bottom of the workbench, and a stepper motor is fixedly installed on one side of the workbench.

[0011] The present invention, as described above, is a device for uniformly cutting anti-displacement antibacterial flash-evaporation composite nonwoven fabric. Further, a rotating roller is rotatably installed between two fixed blocks, and the two rotating rollers are connected by a conveyor belt. The output shaft of the stepper motor is fixedly connected to one of the rotating rollers, and an opening adapted to the conveyor belt is provided on the top of the worktable.

[0012] In summary, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model adopts a design that adds a pre-compression structure that can move and work together with the cutting blade. Before the cutting blade cuts the non-woven fabric, it pre-compresses the non-woven fabric to prevent the non-woven fabric from shifting due to compression. This ensures that the size of the non-woven fabric cut each time is the same, so as to meet the subsequent use needs of the non-woven fabric, reduce the waste of material costs, and provide convenience for users' work.

[0014] 2. This utility model features connecting bolts and grooves. The grooves are used to install the rubber strip and also to position it, preventing it from moving freely during operation. The rubber strips also protect the non-woven fabric from damage, providing convenience for users. The connecting bolts are used to fix the rubber strip and also make it easy for users to disassemble and replace it.

[0015] 3. This utility model features an electric push rod, which drives the cutting blade to move up and down for cutting. Once the non-woven fabric is in place, the electric push rod can be activated to move the cutting blade down to cut the non-woven fabric, providing convenience for users.

[0016] 4. This utility model features a worktable and a limiting slide groove. The limiting slide groove is designed to allow the limiting slider to slide. When the cutting blade moves, the limiting slider will slide within the limiting slide groove, thereby limiting the movement of the limiting slider and the cutting blade, ensuring the stability of the cutting operation, and providing convenience for the user.

[0017] 5. This utility model incorporates a baffle to prevent the cut nonwoven fabric from falling to the ground before the user collects it, thus ensuring the cleanliness of the nonwoven fabric and providing convenience for the user's work.

[0018] 6. This utility model, through the setting of a fixed block, rotating roller, stepper motor and conveyor belt, enables the stepper motor to start and drive one of the corresponding rotating rollers to rotate during operation. Then, with the cooperation of the conveyor belt, the other rotating roller will also rotate. In this way, the cut non-woven fabric pushed onto the conveyor belt will be transported out, avoiding the cut non-woven fabric from clogging the machine and providing convenience for the user's cutting work.

Detailed Implementation

[0025] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0026] A device for uniformly cutting anti-displacement antibacterial flash-evaporation composite nonwoven fabric includes a gantry frame 1. A cutter 2 is slidably mounted inside the gantry frame 1. Both ends of one side of the cutter 2 are fixedly connected to limiting sliders 3 that slide inside the gantry frame 1. A mounting frame 4 is detachably mounted on one side of the two limiting sliders 3. Sliding screws 5 are provided through the top of the mounting frame 4 on both sides. A pressure block 6 is fixedly connected to the bottom end of the two sliding screws 5. A spring 8 is sleeved on the surface of the sliding screw 5. Both ends of the spring 8 are fixedly connected to the mounting frame 4 and the pressure block 6, respectively. An adjusting nut 7 adapted to the mounting frame 4 is threaded onto the surface of the sliding screw 5. A rubber strip 9 is detachably mounted on the bottom of the pressure block 6.

[0027] The specific usage process is as follows: During the cutting process, the user places multiple layers of non-woven fabric stacked together onto the machine and measures the required size of the non-woven fabric according to the machine's built-in measuring structure. During this process, the user needs to continuously adjust the position of the non-woven fabric; this is existing technology, and most cutting machines on the market have measuring scales. Then, the machine can be turned on for cutting. During operation, the electric push rod 12 starts and pushes the cutter 2 downwards within the gantry 1. Simultaneously, the cutter 2 also drives the limiting slider 3 to slide within the corresponding limiting groove 19. Thus, the cooperation of the limiting slider 3 and the limiting groove 19 limits the downward movement of the cutter 2, ensuring that the cutter 2 moves straight up and down, and guaranteeing the accuracy of the non-woven fabric cutting. To facilitate the user's cutting work, the mounting bracket 4, installed on the two limit sliders 3, and all components mounted on the mounting bracket 4 will also move downwards. That is, the mounting bracket 4 will drive the two sliding screws 5 downwards, which in turn will drive the pressure block 6 downwards. Simultaneously, the rubber strip 9 installed on the pressure block 6 will also move downwards. Finally, the rubber strip 9 will press firmly onto the non-woven fabric, thus compressing the non-woven fabric and preventing displacement. Then, the cutting blade 2 continues to move downwards. At this time, the mounting bracket 4 also continues to move downwards along with the cutting blade 2. Because the rubber strip 9 has already pressed firmly onto the non-woven fabric, the rubber strip 9, pressure block 6, and sliding screws 5 are all restricted and will not move downwards further. The mounting bracket 4 is movably mounted on the two sliding screws 5, therefore, as the cutting blade... As the cutting blade 2 moves downwards, the mounting frame 4 can continue to move downwards, simultaneously sliding on the two sliding screws 5. Supported by the mounting frame 4, the sliding screws 5 remain upright in their current position. Guided by the sliding screws 5, the mounting frame 4 moves vertically up and down with the cutting blade 2. Finally, the cutting blade 2 can cut the non-woven fabric. After cutting, the electric push rod 12 retracts, causing the mounting frame 4, pressure block 6, rubber strip 9, and other components to move upwards away from the non-woven fabric. The machine then pauses. The user then pushes the non-woven fabric forward again, moving the portion to be cut below the cutting blade 2. The previously cut non-woven fabric is then pushed onto the conveyor belt 18. With the cooperation of the stepper motor 17, rotating roller 16, and conveyor belt 18, the cut non-woven fabric is delivered. The non-woven fabric, already positioned by the user, is placed correctly. The user then activates the electric push rod 12 again, causing the cutter 2 to move downwards for cutting. As before, the rubber strip 9 first presses firmly onto the non-woven fabric, and then the cutter 2 continues to move downwards to cut the fabric, thus completing the cutting process. This prevents displacement of the non-woven fabric during cutting, providing convenience and improving the accuracy of the cutting. It should be noted that the spring 8 can apply further pressure when the rubber strip 9 presses against the non-woven fabric, enhancing the pressing effect. It also provides the necessary force for the rubber strip 9 and pressure block 6 to reset after cutting, ensuring a smooth and quick reset for the next use.The adjusting nut 7 can adjust the clamping strength of the pressure block 6 and rubber strip 9 on the non-woven fabric to meet the user's work needs. When adjusting, to achieve the required clamping strength, the adjusting nut 7 is turned upwards. This shortens the distance the mounting frame 4 travels downwards with the cutter 2. Therefore, after the pressure block 6 and rubber strip 9 press onto the non-woven fabric, they will continue to apply pressure to the fabric along with the cutter 2. The mounting frame 4, however, cannot adapt to the downward movement of the cutter 2, thus increasing the clamping force on the non-woven fabric. Conversely, when the adjusting nut 7 is turned downwards, the mounting frame... 4. Sufficient distance allows for appropriate movement and adaptation with the cutting blade 2, thus reducing the clamping force on the non-woven fabric and achieving the purpose of adjusting the clamping strength, providing convenience for the user's work. The groove 11 is used to install the rubber strip 9 and can also position the rubber strip 9 to prevent it from moving freely during operation. At the same time, the setting of the rubber strip 9 can also protect the non-woven fabric and prevent damage to it, providing convenience for the user's work. The connecting bolt 10 is used to fix the rubber strip 9 and also... The rubber strip 9 is easy for users to disassemble and replace. The electric push rod 12 is used to drive the cutter 2 to move up and down for cutting. After the non-woven fabric is placed, the electric push rod 12 can be activated to drive the cutter 2 to move down and cut the non-woven fabric, providing convenience for users. The limiting groove 19 is opened for the sliding of the limiting slider 3. In this way, when the cutter 2 moves, the limiting slider 3 will slide in the limiting groove 19, thereby limiting the limiting slider 3 and the cutter 2, ensuring the stability of the cutter 2's cutting work, and providing convenience for users. To facilitate use, the baffle 14 is used to prevent the cut non-woven fabric from falling to the ground before the user collects it, ensuring the cleanliness of the non-woven fabric and providing convenience for the user's work. During operation, the stepper motor 17 starts, driving one corresponding rotating roller 16 to rotate. Then, with the cooperation of the conveyor belt 18, the other rotating roller 16 will also rotate. In this way, the cut non-woven fabric pushed onto the conveyor belt 18 will be conveyed out, preventing the cut non-woven fabric from clogging the machine and providing convenience for the user's cutting work.

[0028] Therefore, a pre-compression structure is added to the design, which can move and work together with the cutting blade. Before the cutting blade cuts the non-woven fabric, the non-woven fabric is pre-compressed to prevent it from shifting due to compression. This ensures that the size of the non-woven fabric cut each time is the same, so as to meet the subsequent use needs of the non-woven fabric, reduce the waste of material costs, and provide convenience for users' work.

[0029] The bottom of the pressure block 6 is provided with a groove 11 that matches the rubber strip 9, and a connecting bolt 10 is provided through the bottom of the rubber strip 9. The rubber strip 9 is fixedly installed on the pressure block 6 by the connecting bolt 10.

[0030] Specifically, the connecting bolt 10 and the groove 11 are designed to install the rubber strip 9 and to position it, preventing it from moving freely during operation. The rubber strip 9 also protects the non-woven fabric from damage, providing convenience for users. The connecting bolt 10 is used to fix the rubber strip 9 and also makes it easy for users to disassemble and replace it.

[0031] An electric push rod 12 is fixedly installed on the top of the gantry frame 1. The output end of the electric push rod 12 passes through the inside of the gantry frame 1 and is fixedly installed on the top of the cutter 2.

[0032] Specifically, the electric push rod 12 is used to drive the cutter 2 to move up and down for cutting. After the non-woven fabric is placed, the electric push rod 12 can be started to drive the cutter 2 to move down to cut the non-woven fabric, providing convenience for users.

[0033] A workbench 13 is fixedly installed at the bottom of the gantry frame 1, and two limiting grooves 19 adapted to the limiting sliders 3 are opened on one side of the gantry frame 1.

[0034] Specifically, the worktable 13 and the limiting slide 19 are designed so that the limiting slide 3 can slide. When the cutting blade 2 moves, the limiting slide 3 will slide in the limiting slide 19, thereby limiting the limiting slide 3 and the cutting blade 2, ensuring the stability of the cutting work of the cutting blade 2, and providing convenience for the user's work.

[0035] A baffle 14 is fixedly installed on one side of the workbench 13.

[0036] Specifically, the baffle 14 is designed to block the cut non-woven fabric from falling to the ground before the user collects it, thus ensuring the cleanliness of the non-woven fabric and providing convenience for the user's work.

[0037] The bottom of the workbench 13 is fixedly connected to four fixed blocks 15. A stepper motor 17 is fixedly installed on one side of the workbench 13. A rotating roller 16 is rotatably installed between two fixed blocks 15. The two rotating rollers 16 are connected by a conveyor belt 18. The output shaft of the stepper motor 17 is fixedly connected to one of the rotating rollers 16. The top of the workbench 13 has an opening that matches the conveyor belt 18.

[0038] Specifically, the arrangement of the fixed block 15, rotating roller 16, stepper motor 17, and conveyor belt 18 ensures that during operation, the stepper motor 17 starts and drives one of the rotating rollers 16 to rotate. Then, with the cooperation of the conveyor belt 18, the other rotating roller 16 will also rotate. In this way, the cut non-woven fabric pushed onto the conveyor belt 18 will be conveyed out, avoiding the cut non-woven fabric from clogging the machine and providing convenience for the user's cutting work.

[0039] It should be noted that the functions to be achieved by each hardware component in this utility model are supported by a large number of mature technologies and belong to the prior art. The essence of this utility model is to optimize and combine existing hardware and its connection methods for specific application scenarios to meet the adaptation requirements of specific application scenarios and solve the problems raised in the background technology (without involving improvements to the internal software of the hardware).
