Description

Technical Field

[0001] The utility model relates to the technical field of extrusion dies, in particular to an acetate diaphragm multi-stage independent temperature-controlled extrusion die. Background Art

[0002] Acetate diaphragms are primarily made from cellulose acetate (also known as cellulose acetate ester or vinegar sheet). Cellulose acetate is a white solid that is flexible, transparent, glossy, strong, tough, melt-flowable, easily moldable, and thermoplastic, making it suitable for use in a wide range of industries. However, the production process for acetate diaphragms places extremely high demands on temperature. The multi-stage, independently temperature-controlled extrusion die, through its built-in temperature control system, enables independent temperature control of different sections within the die. This precise temperature control ensures uniform heating of the cellulose acetate ester during extrusion, preventing overheating or overcooling that could degrade material performance or result in poor diaphragm quality.

[0003] However, the prior art has the following problems: when the extrusion head is in a non-working state, there is a lack of effective protection measures, which makes it easy for dust and impurities in the external environment to invade the interior of the extrusion head. Such pollution problems will cause impurities to adhere to the acetate film during the acetate film extrusion process, thereby reducing the production quality of the acetate film.

[0021] See Figure 1 and Figure 2 In the embodiment of the present invention, an acetic acid diaphragm multi-stage independent temperature control extrusion mold comprises: an extrusion head body 1, an unsealing component 2, the extrusion head body 1 is provided with four groups, and each two groups of unsealing components 2 are used in conjunction with each other. The unsealing components 2 are symmetrically arranged on both sides of the extrusion head body 1, and the unsealing components 2 are used to drive the sealing plate 4 to protect the extrusion port, the tightening structure 3, the tightening structure 3 is the same as the number of the extrusion head body 1, the tightening structure 3 is arranged on both sides of the extrusion head body 1, the tightening structure 3 is used to connect the unsealing component 2 and the sealing plate 4, the sealing plate 4, there are two sealing plates 4 symmetrically arranged up and down, the sealing plate 4 is arranged on one side of the extrusion port, the top and bottom sides of the sealing plate 4 are inclined, the top of the upper sealing plate 4 is rotatably provided with a side cover plate 401, and the bottom end of the lower sealing plate 4 is rotatably provided with a side cover plate 401, and a fixed slide 101 is slidably provided between the side covers 401, and the fixed slide 101 is fixedly provided at the top and bottom ends of the extrusion head body 1.

[0022] Driven by the unsealing component 2, the sealing plate 4 can slide from the top of the fixed slide 101 and slowly move to the extrusion port position until the two sealing plates 4 are aligned and fit together, thereby protecting the extrusion port, preventing the extrusion port from being contaminated, and improving the production quality of the acetic acid diaphragm.

[0023] See Figure 2 、 Figure 3 and Figure 4The unsealing component 2 includes an incomplete gear 201, an adapter column 202 is fixedly provided on the inner side of the incomplete gear 201, and the adapter column 202 is rotatably provided on one side of the extruder head body 1. The outer side of the incomplete gear 201 is meshed and connected with a driving tooth plate 203. The bottom end of the driving tooth plate 203 is slidably provided with a fixed rail frame 204. One side of the driving tooth plate 203 is detachably provided with a connecting plate frame 205. The top of the connecting plate frame 205 is fixedly provided with a handle 206. The fixed rail frame 204 is fixedly provided on one side of the extruder head body 1. The unsealing component 2 also includes a protective Shell 208, an anti-rotation slide plate 211 is slidingly provided on the inner side of the protective shell 208, and a sliding guide column 209 and a return spring 210 are fixedly provided on one side of the anti-rotation slide plate 211. The sliding guide column 209 passes through and is slidably provided on one side of the protective shell 208, and the return spring 210 is fixedly provided on one side of the inner part of the protective shell 208. A clamping block 212 is fixedly provided on the other side of the anti-rotation slide plate 211, and one side of the clamping block 212 is inclined. A connecting arm plate 207 is fixedly provided on one side of the protective shell 208, and the connecting arm plate 207 is detachably provided on one side of the connecting plate frame 205.

[0024] By holding the handle 206 in the unsealing assembly 2 and pulling the handle 206 to one side, the connecting plate frame 205 moves accordingly. The movement of the connecting plate frame 205 drives the two driving gear plates 203 to move together. The movement of the driving gear plates 203 causes the incomplete gear 201 and the adapter column 202 to rotate. The connection of the tensioning structure 3 drives the sealing plate 4 to move, so that the sealing plate 4 can achieve a protective effect on the extrusion outlet.

[0025] When the connecting plate frame 205 moves into place, it will contact the block 212, so that the block 212 will drive the anti-rotation slide plate 211 to move inside the protective shell 208, and the sliding guide column 209 will be compressed. Through the elastic force of the sliding guide column 209, the anti-rotation slide plate 211 and the block 212 will return to their original positions, thereby locking the connecting plate frame 205 to prevent the sealing plate 4 from being unlocked at will. When unlocking, pull the sliding guide column 209 to make the block 212 leave the connecting plate frame 205, and then the connecting plate frame 205 can be moved at will.

[0026] See Figure 1 and Figure 2 The tensioning structure 3 includes a tensioning spring 301, and the two ends of the tensioning spring 301 are respectively fixed with a first end seat 303 and a second end seat 304, and the top of the first end seat 303 and the second end seat 304 are rotatably provided with a connecting rod 302, and the connecting rods 302 are rotatably connected. The first end seat 303 is fixedly set on the outside of the adapter column 202, and the initial state of the tensioning spring 301 is extended, and the second end seat 304 is fixedly set on one side of the sealing plate 4.

[0027] Among them, the rotation of the adapter column 202 drives the first end seat 303 to rotate, so that the first end seat 303 drives the sealing plate 4 to move through the setting of the connecting rod 302 and the second end seat 304, and the sealing plate 4 slowly slides down from the top of the fixed slide plate 101, and the tensioning spring 301 is always in an extended state, providing tension for the sealing plate 4 to prevent the sealing plate 4 from deviating from the predetermined moving trajectory.

[0028] The working principle of the present invention is as follows: when the sealing plate 4 is not in use, the sealing plate 4 is fitted with the fixed slide 101, and the tensioning spring 301 in the tensioning structure 3 is in an extended state. When the extrusion port on one side of the extruder head body 1 is protected, the handle 206 in the unsealing component 2 is held and pulled to one side to cause the connecting plate frame 205 to move with it. The movement of the connecting plate frame 205 drives the two driving tooth plates 203 to move together. The movement of the driving tooth plates 203 causes the incomplete gear 201 and the adapter column 202 to rotate, and the rotation of the adapter column 202 drives the connecting plate frame 205 to move with it. The first end seat 303 rotates, so that the first end seat 303 drives the sealing plate 4 to move through the setting of the connecting rod 302 and the second end seat 304, and the sealing plate 4 slowly slides down from the top of the fixed slide plate 101, and the tension spring 301 is always in the extended state, providing tension for the sealing plate 4 to prevent the sealing plate 4 from deviating from the predetermined moving trajectory until the two sealing plates 4 are attached together. At this time, the sealing plate 4 can protect the extrusion port, and the side cover 401 prevents large particles of impurities from entering the gap between the sealing plate 4 and the extrusion port, thereby achieving a better protection effect;

[0029] It should be noted that when the connecting plate frame 205 moves into place, it will contact the block 212, so that the block 212 will drive the anti-rotation slide plate 211 to move inside the protective shell 208, and the sliding guide column 209 will be compressed. Through the elastic force of the sliding guide column 209, the anti-rotation slide plate 211 and the block 212 will return to their original positions, thereby locking the connecting plate frame 205 to prevent the sealing plate 4 from being unlocked at will. When unlocking, pull the sliding guide column 209 to make the block 212 leave the connecting plate frame 205, and then the connecting plate frame 205 can be moved at will.

[0030] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
