Description

Technical Field

[0001] The utility model relates to the technical field of film blowing printing machines, in particular to a film blowing printing machine with stable operation. Background Art

[0002] The film blowing machine heats and melts plastic particles and then blows them into thin films. There are many types of film blowing machines, including PE, POF, PVC, etc. The new materials blown out with new particles are new materials with uniform color, clean, and good bag stretching. Most of the machines used to make plastic products on the market integrate film blowing, printing, and winding. During the film blowing process, the uniformity of the raw materials is an important indicator of the quality of the film.

[0003] The feed hopper of the existing film blowing machine lacks a screening structure for plastic particles, which causes incomplete melting of plastic particles with larger particle sizes in the film blowing machine. This not only affects the quality of the film blowing, but also the incompletely melted plastic particles easily cause problems such as blockage of the film blowing machine, affecting the working stability of the film blowing machine. In this regard, we propose a stable film blowing printing machine. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: a stable film blowing printing machine, comprising:

[0021] A machine body 1 is provided, with a feed hopper 2 installed on the machine body 1, a storage hopper 3 is provided above the feed hopper 2, a mounting frame 4 is fixedly installed on the storage hopper 3, the mounting frame 4 is fixedly installed on the feed hopper 2, a screen 5 is provided in the feed hopper 2, a pair of fixing seats 6 are fixedly bonded to the inner walls on both sides of the feed hopper 2, a pair of slide bars 7 are fixedly bonded to the bottom wall of the screen 5, the slide bars 7 are slidably connected to the fixing seats 6, a spring 8 is sleeved on the slide bar 7, the two ends of the spring 8 are respectively fixedly connected to the bottom wall of the screen 5 and the top wall of the fixing seat 6, and a pull rod 9 is fixedly bonded to the top wall of the screen 5.

[0022] A portal frame 10 is fixedly installed on the side wall of the feed hopper 2, and a driving motor 11 is fixedly installed on the portal frame 10. The output end of the driving motor 11 is transmission-connected with a first rotating rod 12, and a cam 13 is fixedly installed on the first rotating rod 12. An L-shaped connecting rod 14 is fixedly installed on the top of the pull rod 9, and a roller 15 is fixedly installed on the bottom end of the L-shaped connecting rod 14. The roller 15 is rollingly connected with the cam 13. After the driving motor 11 is started, it can drive the first rotating rod 12 to rotate. When the first rotating rod 12 rotates, it can drive the cam 13 to rotate. During the rotation of the cam 13, the roller 15 can be circulated and squeezed, so that the L-shaped connecting rod 14 drives the pull rod 9 to move up and down reciprocatingly, thereby driving the screen 5 to vibrate, screen the plastic particles, and improve the screening effect.

[0023] A lower material barrel 16 is fixedly installed below the storage hopper 3, and a second rotating rod 17 is rotatably installed at the center of the lower material barrel 16. A mounting sleeve 18 is fixedly installed on the second rotating rod 17, and a plurality of annular rotating plates 19 equidistantly distributed are fixedly installed on the mounting sleeve 18. The rotating plates 19 are slidably connected in the inner cavity of the lower material barrel 16. When the second rotating rod 17 rotates, it can drive the plurality of rotating plates 19 to rotate, so that the plastic particles in the storage hopper 3 fall onto the screen 5 in batches.

[0024] One end of the second rotating rod 17 extends to the outside of the discharge barrel 16 and a first pulley 20 is fixedly installed at the end. A second pulley 21 is fixedly installed on the first rotating rod 12. The first pulley 20 and the second pulley 21 are connected by a transmission belt 22. Through the cooperation of the first pulley 20, the second pulley 21 and the transmission belt 22, the second rotating rod 17 can be driven to rotate when the first rotating rod 12 rotates, thereby reducing the setting of the driving source.

[0025] The diameter of the first pulley 20 is greater than that of the second pulley 21 , so that the rotation speed of the first rotating rod 12 is higher than that of the second rotating rod 17 , so that each drop of material on the screen 5 can be effectively vibrated and screened multiple times.

[0026] Working principle: The utility model screens the plastic particles entering the machine body 1 through the screen 5 set in the feed hopper 2. During the screening process, the driving motor 11 can drive the first rotating rod 12 to rotate after it is started. When the first rotating rod 12 rotates, it can drive the cam 13 to rotate. During the rotation of the cam 13, the roller 15 can be squeezed cyclically, so that the L-shaped connecting rod 14 drives the pull rod 9 to move up and down reciprocatingly, thereby driving the screen 5 to vibrate, screen the plastic particles, improve the screening effect, and avoid the incomplete melting of some plastic particles due to the excessive particle size, which not only affects the quality of the blown film, but also the incomplete melting. Plastic particles can easily cause problems such as clogging of the film blowing machine, affecting the working stability of the film blowing machine. By cooperating with the first pulley 20, the second pulley 21 and the transmission belt 22, the second rotating rod 17 can be driven to rotate when the first rotating rod 12 rotates, and the second rotating rod 17 can drive multiple rotating plates 19 to rotate when it rotates, so that the plastic particles in the storage hopper 3 fall into the screen 5 in batches, and multiple vibration screening is performed, thereby realizing vibration screening of plastic particles in batches, avoiding the accumulation of plastic particles on the screen 5, causing screening inconvenience, and further improving the screening effect of the screen 5.
