Embodiment 1

[0043] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the post-processing system for degradable matte film casting includes a slitting device 1, and the slitting device 1 includes a cutter mechanism 11 for cutting off the side waste film 10 of the casting film and a In the cutting process, the support mechanism 12 that presses and supports the waste film 10; the buffer device 2, the buffer device 2 is arranged behind the cutting device 1, the buffer device 2 includes a water tank 21, and is arranged in the water tank 21 A buffer mechanism 22 for making the waste film 10 into a U-shaped transmission from the inside of the water tank 21; a winding device 3, which is arranged behind the buffer device 2, and the winding device 3 includes a winding A mechanism 31 and a control mechanism 32 , the winding mechanism 31 is used for winding the waste film 10 , and the control mechanism 32 adjusts the winding speed of the winding me...

Embodiment 2

[0058] Such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the components that are the same as or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. The difference between the second embodiment and the first embodiment is that further, a blowing mechanism 4 for drying the waste film 10 coming out of the water tank 21 is provided between the water tank 21 and the winding device 3, The blowing mechanism 4 includes a blower 41 and a blower cover 42 communicating with the blower 41 , and a plurality of support rollers 43 are arranged below the air outlet of the blower cover 42 .

[0059] In this embodiment, the blowing mechanism 4 is set so that the waste film 10 can remove the moisture brought by the waste film 10 from the water tank 21 by the blowing mechan...

Embodiment 3

[0061] Such as Figure 8 As shown, the post-processing process of degradable matt film tape casting includes the following production steps:

[0062] a. Slitting process, the cast film is transported to the slitting station, and the slitting device 1 at the slitting station cuts off the waste film 10 on the side of the cast film and removes the waste film 10 during the cutting process. The membrane 10 is pressed down to support;

[0063] b. buffering process, the cut waste film 10 is transported to the buffer station, and the buffer device 2 makes the waste film 10 into a U shape and is transported through the water tank 21;

[0064] c. Rewinding process, the waste film 10 transmitted through the water tank 21 is transported to the rewinding station, and the rewinding mechanism 31 located at the rewinding station rewinds the waste film 10;

[0065] d. Adjustment process, during the process of winding up the waste film 10 by the winding mechanism 31 in step c, the control mec...

Abstract

The invention relates to a tape-casting post-treatment system and technology for a degradable matte film. The system comprises a cutting device, a buffering device and a winding device, wherein the cutting device comprises a cutter mechanism for cutting off a side edge waste film of a casting film and a supporting mechanism for pressing and supporting the waste film in a cutting process; the buffering device is arranged behind the cutting device; the buffering device comprises a water tank and a buffering mechanism which is arranged in the water tank and is used for enabling the waste film topass through the water tank in a U shape; the winding device is arranged behind the buffering device; the winding device comprises a winding mechanism and a control mechanism; the winding mechanism isused for winding the waste film; the control mechanism is used for adjusting a winding speed of the winding mechanism under the action of the buffering mechanism. According to the tape-casting post-treatment system and technology, provided by the invention, the problems that cutting is not stable in a cutting process of the side edge waste film of the casting film, the cut-off waste film is difficult to wind intensively, the casting film is easily dragged in a winding process so that the quality of the tape-casting film is influenced are solved.

Description

technical field [0001] The invention relates to the technical field of tape casting equipment, in particular to a post-processing system and process for tape casting of a degradable matte film. Background technique [0002] In the process of casting film production, the sides of the film generally need to be cut off, and the cut waste film needs to be recycled. When the waste film is reused, the ratio between it and the raw material masterbatch needs to be controlled within a certain range. The existing technology is unstable when recycling the film, which is easy to cause damage to the film. [0003] The authorized announcement number is a Chinese utility model patent of CN104626434B, which discloses a high-speed casting machine and a method for producing a breathable film. The casting machine includes a frame, casting rollers arranged on the frame in turn, The pressing roller for printing, the sub-cooling roller assembly for film cooling and setting, the casting roller an...
