Description

Technical Field

[0001] This utility model belongs to the field of packaging machine technology, and in particular relates to a screening device for packaging machines. Background Technology

[0002] As the name suggests, a packaging opener is used to open sealed materials. Most packaging openers currently use blades or similar tools to automatically open the sealing tape and then remove the materials from the sealed bag, thus improving the processing efficiency of materials. Some materials are often mixed together during packaging, so the materials need to be screened after opening.

[0003] Chinese patent discloses a screening device (CN220862013U). This utility model provides a screening device comprising: a driving device, a screen frame, and a screen surface; the driving device is connected to the screen frame and drives the screen frame to vibrate, and the screen surface is installed inside the screen frame; the screen surface is composed of multiple spaced-apart string bodies, the string bodies being made of a flexible material, and all string bodies corresponding to various tensions, with screen holes formed between adjacent string bodies for screening materials. The screen surface is set inside the screen frame, and the driving device is connected to the screen frame and drives the screen frame to vibrate, thereby causing the screen surface to vibrate, so that the material to be screened can quickly pass through the screen surface, avoiding blockage of the material on the screen surface. By setting multiple tension string bodies, during use, the different tension string bodies have different amplitudes. Under the action of alternating amplitudes, sheet-like materials can be broken up, and wet, sticky materials can be dispersed. Compared with the prior art, it can be used for screening sheet-like materials, and the screening effect is better. Packaging machines often encounter packaging bags containing materials with high levels of dust during operation. The opening and screening processes generate a large amount of dust, which pollutes the working environment. The dust generated during screening not only affects the operators but also enters the packaging machine and screening device. As the usage time increases, a large amount of dust accumulates on the packaging machine, leading to malfunctions. Therefore, a screening device for packaging machines is provided. Utility Model Content

[0018] 1. In this utility model, by setting up a dust suppression component, the conveyor belt drives the second conveyor roller to rotate when it moves. At this time, the second conveyor roller drives the drive disc to rotate through the fixed rod. As the drive disc rotates, under the action of the movable rod, the piston plate moves back and forth in the piston cylinder through the mounting clamp. Water from the water tank is drawn into the piston cylinder through the water inlet pipe, and then transported to the water spray pipe through the water outlet pipe and sprayed from the water spray hole to the surrounding area of ​​the mounting frame. This process suppresses the dust generated during material screening, reduces the degree of dust pollution to the working environment during opening, ensures the freshness of the working environment air, further reduces the impact of dust on operators and machines, and improves the service life of the opening machine.

[0019] 2. In this utility model, a screening component is provided. The drive motor inside the mounting cover drives the connecting rod to rotate. When the connecting rod rotates, it drives the rotating disk to rotate. Under the connection of the rotating shaft, the screening frame moves within the mounting frame to screen the material. The material that falls off the screen falls onto the conveyor belt. When the connecting rod rotates, it drives the first toothed sprocket to rotate. Under the action of the toothed chain, the second toothed sprocket drives the first conveyor roller to rotate through the positioning rod, thereby causing the conveyor belt to move under the support of the second conveyor roller. Then, the material on the conveyor belt is moved out of the mounting frame. At the same time as screening, the material that falls off the screen is automatically transported out of the screening device, reducing the subsequent material processing steps and improving the working efficiency and convenience of the screening device.

Under the action of the toothed chain, the second toothed sprocket 46 drives the first conveyor roller 45 to rotate through the positioning rod, thereby causing the conveyor belt 48 to move on the second toothed sprocket 48. Supported by the conveyor roller 47, the material on the conveyor belt 48 is moved out of the mounting frame 1. When the conveyor belt 48 moves, it will drive the second conveyor roller 47 to rotate. At this time, the second conveyor roller 47 drives the drive disc 6 to rotate through the fixed rod. As the drive disc 6 rotates, under the action of the movable rod 58, the piston plate 56 is driven to move back and forth in the piston cylinder 51 through the mounting clamp 57. Water from the water tank is drawn into the piston cylinder 51 through the water inlet pipe 52, and then transported to the water spray pipe 54 through the water outlet pipe 53 and sprayed from the water spray hole to the surrounding area of ​​the mounting frame 1 to reduce dust generated during the material screening process.
