Description

Technical Field

[0001] This application relates to the field of dust bag technology, and in particular to a cutting device for dust bag production. Background Technology

[0002] Dust bags are an important protective tool used in industrial production and daily life, widely applied in material storage, transportation, and environmental cleaning to prevent dust from flying and protect the environment and human health. Most dust bags on the market are made of single or multiple layers of fabric, sealed by sewing or heat sealing processes to achieve dust protection.

[0003] Regarding the aforementioned technologies, the inventors believe that dustproof bags require cutting and processing during production. However, some existing dustproof cloth cutting devices struggle to secure the dustproof cloth flat on the cutting table, resulting in uneven edges on the cut fabric, affecting the product's aesthetics and sealing performance, and reducing the overall quality of the dustproof bags. Therefore, an improvement has been made to a cutting device for dustproof bag production to solve the aforementioned problems.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of this application. Therefore, it may contain information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0005] To address the aforementioned problems, this application provides a cutting device for producing dust bags.

[0006] The cutting device for producing dust bags provided in this application adopts the following technical solution:

[0007] A cutting device for producing dust bags includes a processing table with a cutting groove on its outer wall. A cutting blade is installed through the cutting groove on the processing table. Two support frames are fixedly connected to the outer walls of both sides of the processing table. A bidirectional lead screw is provided between the two support frames and is rotatably connected to the two support frames. Two drive seats are threaded to the outer walls of both sides of the bidirectional lead screw. A connecting plate is provided on the processing table below the two drive seats, and two connecting seats are fixedly connected to the outer wall of the connecting plate. Two connecting rods are provided between the two connecting seats and the two drive seats, and the two connecting rods are hinged to the two drive seats and the two connecting seats. A pressing plate is bolted to the outer wall of the connecting plate.

[0008] Preferably, the bottom outer wall of the processing table is fixedly connected to two second supports, and a reciprocating screw is provided between the two second supports. The reciprocating screw is rotatably connected to the two second supports, and a movable seat is threadedly connected to the outer wall of the reciprocating screw.

[0009] Preferably, two first supports are fixedly connected to the outer walls of both sides of the processing table, and a rolling roller is provided between the two first supports, and the rolling roller is rotatably connected to the two first supports.

[0010] Preferably, a limiting rod is provided between the two support frames, and the limiting rod is fixedly connected to the two support frames and slidably connected to the two drive seats.

[0013] Preferably, a drive motor is fixedly connected to the outer wall of the second bracket, and the output shaft of the drive motor is fixedly connected to a reciprocating lead screw.

[0014] In summary, this application has the following beneficial technical effects:

[0015] The dust bag is first slightly stabilized by rolling rollers on both sides. Then, the bidirectional screws on both sides rotate synchronously, causing the two drive seats to move up and down through the two connecting rods. This causes the connecting plate to press and fix the dust bag below, ensuring the stability of both sides of the dust bag at the cutting position. This facilitates cutting. Compared with existing technologies, this method can stabilize both sides of the dust bag during the cutting process, effectively ensuring the consistency of the cutting edges and improving the quality of cutting.

[0021] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0022] Example 1:

[0023] A cutting device for producing dust bags includes a processing table 1. A cutting groove 19 is formed on the outer wall of the processing table 1. A cutting blade 14 is installed through the cutting groove 19 on the processing table 1 for cutting the dust bags. Two support frames 4 are fixedly connected to the outer walls of both sides of the processing table 1. A bidirectional lead screw 6 is installed between the two support frames 4. The two sides of the bidirectional lead screw 6 have the same thread pitch but opposite thread directions, and are rotatably connected to the two support frames 4. Two drive seats 8 are threaded to the outer walls of both sides of the bidirectional lead screw 6. By driving the bidirectional lead screw 6 to rotate, the bidirectional lead screw 6 drives the drive seats 8 on both sides to move in opposite directions or towards each other. The processing table 1 is located between the two support frames 4. A connecting plate 9 is provided below each drive seat 8, and two connecting seats 11 are fixedly connected to the outer wall of the connecting plate 9. Two connecting rods 12 are provided between the two connecting seats 11 and the two drive seats 8, and the two connecting rods 12 are hinged to the two drive seats 8 and the two connecting seats 11. By moving the two drive seats 8, the two drive seats 8 drive the connecting plate 9 to move up and down through the two connecting rods 12. A pressing plate 10 is bolted to the outer wall of the connecting plate 9. By moving the two connecting plates 9 up and down, they drive the pressing plate 10 to move synchronously, so that the pressing plate 10 presses and stabilizes the dust bag placed below. Then, the blade 14 cuts it to improve the cutting quality.

[0024] The bottom outer wall of the processing table 1 is fixedly connected to two second supports 16, and a reciprocating screw 18 is provided between the two second supports 16. The reciprocating screw 18 is provided with two threaded grooves with the same pitch and opposite directions. The reciprocating screw 18 is rotatably connected to the two second supports 16. The outer wall of the reciprocating screw 18 is threadedly connected to a movable seat 15. The movable seat 15 is slidably connected to the cutting groove 19 and has a certain limit on it. The blade 14 is fixedly installed on the outer wall of the movable seat 15. The drive motor 17 is started by an external power switch, so that the output shaft of the drive motor 17 drives the reciprocating screw 18 to rotate, thereby driving the movable seat 15 to move back and forth, and then the movable seat 15 drives the blade 14 to move back and forth for cutting.

[0025] The processing table 1 has two first supports 3 fixedly connected to the outer walls on both sides. A rolling roller 2 is provided between the two first supports 3 and the rolling roller 2 is rotatably connected to the two first supports 3. By setting the rolling roller 2 on both sides, the dust bag passes through the rolling roller 2 to the rolling roller 2 on the other side, which facilitates the slight stability of cutting it.

[0026] A limiting rod 7 is provided between the two support frames 4, and the limiting rod 7 is fixedly connected to the two support frames 4. The limiting rod 7 is slidably connected to the two drive seats 8. The slidable connection between the limiting rod 7 and the two drive seats 8 facilitates the limiting of the two drive seats 8.

[0027] The outer walls of the two support frames 4 are provided with sliding grooves 13, and the connecting plate 9 is slidably connected to the two sliding grooves 13. By sliding the connecting plate 9 through the sliding grooves 13, the connecting plate 9 can be limited to prevent it from shifting.

[0028] Servo motors 5 are fixedly connected to the outer side walls of both support frames 4, and the output shafts of the servo motors 5 are fixedly connected to the bidirectional lead screws 6. By connecting an external power switch, the servo motors 5 on both sides are started synchronously, so that their output shafts drive the two bidirectional lead screws 6 to rotate synchronously.

[0029] The outer wall of the second bracket 16 is fixedly connected to a drive motor 17, and the output shaft of the drive motor 17 is fixedly connected to the reciprocating lead screw 18. The drive motor 17 is started by an external power supply, so that the output shaft of the drive motor 17 drives the reciprocating lead screw 18 to rotate.

[0030] The implementation principle of the cutting device for dust bag production in this embodiment is as follows: First, the dust bag to be cut is passed through the rolling roller 2 to the other side of the rolling roller 2 to place the dust bag. Then, the servo motors 5 on both sides are started synchronously by an external power switch. The output shafts of the servo motors 5 on both sides drive the bidirectional lead screw 6 to rotate synchronously at the same frequency. Then, the bidirectional lead screw 6 drives the drive seats 8 on both sides to move relative to each other. This ensures that the two drive seats 8 drive the connecting plate 9 to move down through the two connecting rods 12. The connecting plate 9 drives the pressing plate 10 to press and fix the dust bag below. After the dust bag production material is stabilized, the drive motor 17 can be started by an external power supply. Its output shaft drives the reciprocating lead screw 18 to rotate. This causes the reciprocating lead screw 18 to drive the moving seat 15 to move back and forth. Then, the moving seat 15 drives the blade 14 to cut the dust bag to ensure that it is easy to process in subsequent processes.

[0031] The foregoing description, with reference to preferred embodiments, illustrates an exemplary implementation of a cutting device for producing dust bags provided by this disclosure. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, the protection scope of which is determined by the appended claims.
