Technical Field

[0001] This utility model belongs to the field of garbage bag processing technology, specifically relating to a pneumatic embossing device for bag making. Background Technology

[0002] With the advancement of household waste sorting and the upgrading of cleaning needs in commercial settings, the garbage bag market is showing characteristics of large-scale and multi-specification production. The core production materials are mainly polyethylene (PE) and polypropylene (PP). These thermoplastic plastics need to be mass-produced through a continuous process of "blown film - printing - bag making - embossing". Among them, the embossing process directly determines the performance and market competitiveness of garbage bags, making it a key link in the production line.

[0003] The prior art patent publication number CN213861000U describes a CPP film embossing device. This patent uses a preheating device on the left side of the embossing device to heat the air using a heating tube. A fan then delivers the heated air to the CPP film to preheat it, softening the film in advance. This facilitates subsequent embossing and reduces the difficulty of embossing. However, in practical use, this device still has the following shortcomings: In practice, when used to emboss garbage bags, the embossing roller is fixed and cannot be replaced. Therefore, it cannot meet the embossing requirements of different products, reducing the applicability and flexibility of the device.

[0004] Therefore, a pneumatic embossing device for bag making is needed to solve the problem that the fixed setting of the embossing roller in the existing technology cannot meet the embossing requirements of different products. Utility Model Content

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figure 1-4 This utility model provides a pneumatic embossing device for bag making, including a worktable 1, a support roller 2, a fixed bracket 3, a pressing mechanism 4, an embossing mechanism 5, and a transmission roller 6. The support roller 2 is symmetrically arranged on the upper left and right sides of the worktable 1. The fixed bracket 3 is fixedly connected to the upper middle part of the worktable 1. The pressing mechanism 4 is arranged below the fixed bracket 3. The embossing mechanism 5 is arranged inside the pressing mechanism 4. The transmission roller 6 is arranged below the embossing mechanism 5.

[0024] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that the pressing mechanism 4 consists of a cylinder 401, a U-shaped connecting frame 402, a moving block 403, and a roller 404. The cylinder 401 is fixedly connected to the top of the fixed bracket 3, the U-shaped connecting frame 402 is fixedly connected to the extended end of the cylinder 401, and the moving block 403 is symmetrically fixedly connected to the front and rear sides of the U-shaped connecting frame 402.

[0025] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that the rollers 404 are symmetrically fixedly connected to the left and right sides of the moving block 403, and the inner wall of the fixed bracket 3 is provided with limiting grooves 405 that are adapted to the rollers 404 on the front and rear sides.

[0026] The rollers 404 on the moving blocks 403 on both sides of the U-shaped connecting frame 402 cooperate with the limiting grooves 405 on the inner wall of the fixed bracket 3, which play a good role in limiting and guiding the movement of the U-shaped connecting frame 402, ensuring the stability of the embossing mechanism 5 during the pressing process.

[0027] As can be seen from the above working process: the pressing mechanism 4 is set up, and the cylinder 401 is used as the power source. The cylinder 401 can provide stable and large downward pressure to ensure that the embossing roller 512 has enough pressure to emboss the garbage bag. At the same time, the design of the moving block 403, the roller 404 and the limiting groove 405 plays a good role in limiting and guiding the movement of the U-shaped connecting frame 402, ensuring the stability of the embossing mechanism 5 during the pressing process, making the embossing quality more uniform and stable, and improving the product qualification rate.

[0028] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the embossing mechanism 5 consists of a rotating shaft 501, a mounting frame 502, a lead screw 503, a handle 504, a threaded block 505, a rotating disk 506, a rotating rod 507, a connecting block 508, a cross block 509, a clamping plate 510, a positioning block 511, an embossing roller 512, a mounting block 513, and a limiting block 514. The rotating shaft 501 is symmetrically rotatably connected to the front and rear sides of the interior of the U-shaped connecting frame 402. The mounting frame 502 is fixedly connected to one end of the rotating shaft 501, and an installation cavity is provided inside the mounting frame 502.

[0029] The rotating shaft 501 can drive the embossing roller 512 to rotate inside the U-shaped connecting frame 402, thereby embossing the garbage bag passing between the embossing roller 512 and the transmission roller 6.

[0030] Further as Figure 2 , Figure 3 and Figure 4As shown, it is worth noting that the lead screw 503 is rotatably connected to the inside of the mounting cavity, the handle 504 is fixedly connected to the right end of the lead screw 503, the threaded block 505 is threadedly connected to the outside of the lead screw 503, and a slider is fixedly connected to the rear side of the threaded block 505, which is slidably connected to the inside of the mounting cavity.

[0031] Since the threaded block 505 is threadedly connected to the lead screw 503, and the threaded block 505 is limited in the mounting cavity by the slider, the rotation of the lead screw 503 will cause the threaded block 505 to move.

[0032] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the rotating disk 506 is rotatably connected to the inside of the mounting cavity, the rotating rod 507 is symmetrically rotatably connected to the left and right sides of the rotating disk 506, a cross groove is provided on the front side of the mounting cavity, the cross block 509 is slidably connected to the inside of the cross groove, the connecting block 508 is fixedly connected to the rear side of the cross block 509, one end of the rotating rod 507 is rotatably connected to the connecting block 508, the threaded block 505 is fixedly connected to the rear of the right connecting block 508, the clamping plate 510 is fixedly connected to the front side of the cross block 509, and the positioning block 511 is fixedly connected to the opposite side of the clamping plate 510.

[0033] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth noting that the mounting block 513 is symmetrically rotated and connected to the front and rear sides of the embossing roller 512, the limiting block 514 is fixedly connected to the front side of the mounting block 513, and the mounting frame 502 has a limiting groove adapted to the limiting block 514 inside, and the mounting block 513 has positioning grooves adapted to the positioning block 511 on the left and right sides.

[0034] Align the limiting block 514 with the limiting groove of the mounting frame 502 and insert it to initially position the mounting block 513, so that the mounting block 513 can be fixedly installed inside the mounting frame 502 later.

[0035] The front end of the transmission roller 6 is equipped with a synchronous wheel and a motor. The motor drives the synchronous wheel to rotate the transmission roller 6, thereby transporting the garbage bag.

[0036] The solution has the following working process: First, according to the actual use requirements, select a suitable embossing roller 512, insert the limiting block 514 into the limiting groove of the mounting frame 502, and at the same time make the positioning groove of the mounting block 513 correspond to the positioning block 511. Then, turn the handle 504 to drive the screw 503 to rotate, and drive the right connecting block 508 to move to one side of the rotating disk 506 through the threaded block 505. Drive the rotating disk 506 to rotate through the rotating rod 507. The rotating rod 507 on the other side of the rotating disk 506 drives the left connecting block 508 and the cross block 509 to slide in the cross groove at the same time, and then drive the two clamping plates 510 to move towards the middle, so that the positioning block 511 is inserted into the positioning groove of the mounting block 513, and fix the embossing roller 512 on the mounting frame 502.

[0037] Start the motor at the front end of the drive roller 6. The motor drives the synchronous pulley to rotate, and the synchronous pulley drives the drive roller 6 to rotate. Place the garbage bag to be embossed on the worktable 1, so that one end of the garbage bag passes between the embossing roller 512 and the drive roller 6. Under the rotation of the drive roller 6, the garbage bag is continuously transported, and at the same time, the embossing roller 512 is driven to rotate inside the U-shaped connecting frame 402 through the rotating shafts 501 at both ends. The U-shaped connecting frame 402 drives the embossing mechanism 5 to move downward, so that the garbage bag between the embossing roller 512 and the drive roller 6 is subjected to pressure. Under the action of the embossing roller 512, the surface of the garbage bag is pressed with the corresponding texture, completing the embossing operation.

[0038] When it is necessary to replace the embossing roller 512 with a different texture, turn the handle 504 in the opposite direction and follow the reverse process of installing the embossing roller 512 to move the two clamps 510 outward at the same time, release the fixation of the embossing roller 512, then take out the embossing roller 512, and repeat the installation steps to replace it with a new embossing roller 512.

[0039] In summary: The pressing mechanism 4, powered by cylinder 401, provides stable and significant downward pressure, ensuring sufficient pressure on the embossing roller 512 for embossing the garbage bag. Simultaneously, the design of the moving block 403, roller 404, and limiting groove 405 effectively limits and guides the movement of the U-shaped connecting frame 402, ensuring the stability of the embossing mechanism 5 during the pressing process. This results in more uniform and stable embossing quality, improving the product qualification rate. Furthermore, the embossing mechanism 5 allows for easy movement of the two side clamps 510 by rotating the handle 504, facilitating the installation and removal of the embossing roller 512. This enables operators to quickly change the embossing roller 512 according to different embossing needs, significantly reducing changeover time, improving production efficiency, and simultaneously reducing operational difficulty and labor intensity.
