Description

Technical Field

[0001] This utility model relates to the field of nylon film molding technology, specifically to an intelligent adjustment die head for nylon films. Background Technology

[0002] In the field of nylon film production, the die head is the core component of melt forming. The die head, together with the bottom die, forms the extrusion gap, and its performance directly determines the film thickness uniformity, production efficiency, and product quality. With the increasing demands for nylon film quality from high-precision applications such as food packaging and electronic insulation, traditional nylon film dies exhibit the following defects during use, as detailed below: Traditional nylon film dies require manual adjustment of the die lip gap and melt film thickness during the melt forming process. Operators need to visually inspect or use offline measuring tools to check the melt film thickness and then manually adjust the die position to correct the gap. This manual adjustment method makes it difficult to accurately control the melt film thickness, resulting in poor uniformity of film thickness in the transverse direction, which makes it difficult to meet the high precision requirements of food packaging for film barrier properties and electronic insulation for film insulation. On the other hand, when the deviation in the melt film thickness is discovered, a large number of defective products have already been produced, and the adjustment process requires frequent machine shutdowns, which seriously reduces production efficiency. In addition, traditional die heads have a height adjustment threaded hole directly on one side. When the threaded hole wears out, the entire die head needs to be replaced, which increases the replacement cost due to thread wear. Utility Model Content

A multi-element sensor 204 has a mounting hole in its center for mounting a micro-actuator 205. An isolation glass 206 is mounted inside the mounting hole, located at the bottom of the micro-actuator 205. The multi-element sensor 204 and micro-actuator 205 have a rectangular stepped structure. The mounting hole allows for precise positioning of the multi-element sensor 204 and micro-actuator 205, while the isolation glass 206 effectively prevents contact between the molten film and the micro-actuator 205. An extension plate is provided on one side of the bottom mold 201, aligned with the multi-element sensor 204. The multi-element sensor 204 combines conventional temperature and displacement sensing technologies as needed. The temperature sensing component monitors the molten film exit temperature, eliminating interference from temperature fluctuations on thickness detection. The displacement sensing component detects the distance between the bottom mold 201 and the die head 202, thereby automatically detecting the thickness of the extruded die lip.

[0016] The positioning plate 20201 has two sliding holes inside, through which the second positioning rod 3 passes. A clamping plate 301 is located on one side of the second positioning rod 3. There are two clamping plates 301, each with a U-shaped structure. The clamping plates 301 are positioned above the multi-element sensor 204 and the micro-actuator 205. The bottom side of the clamping plates 301 is in close contact with the upper surfaces of the multi-element sensor 204 and the micro-actuator 205. Specifically, the clamping plates 301 stably clamp the multi-element sensor 204 and the micro-actuator 205 respectively. A support spring is installed on the outer side of the second positioning rod 3. The support spring is located between the clamping plate 301 and the positioning plate 20201. Between 201, the elastic force of the support spring is selected according to actual needs. The support spring pushes the positioning plate 20201 to move closer to the multi-element sensor 204 and the micro actuator 205. An annular groove is opened on one side of the second positioning rod 3, and a retaining spring is installed inside the annular groove. The specific function is: the support spring pushes the clamping plate 301 to quickly clamp the multi-element sensor 204 and the micro actuator 205 through elastic force. After pushing the clamping plate 301 to one side, the multi-element sensor 204 and the micro actuator 205 can be unlocked, realizing the effect of convenient assembly and maintenance of the multi-element sensor 204 and the micro actuator 205, while improving the convenience of assembly and maintenance of the mold head 202.

The threaded rod 207 passes through the rotating hole and is threadedly connected to the nut 209. The thread pitch is processed according to actual needs. Specifically, the positioning groove hides and positions the nut 209 circumferentially. The electric motor 203 drives the threaded rod 207 to rotate. Through the thread engagement of the nut 209, the mold head 202 is automatically adjusted up and down, thereby realizing the gap adjustment between the mold head 202 and the bottom mold 201. With the functions of the micro actuator 205 and the multi-element sensor 204, it meets the production needs of nylon films of different thicknesses. A set of sliding holes is opened on the side of the mold head 202. A first positioning rod 208 is installed through the sliding holes. An external thread is opened at the bottom of the first positioning rod 208. A threaded hole is opened on one side of the stabilizing seat 1, corresponding to the external thread at the bottom of the first positioning rod 208. The external thread at the bottom of the first positioning rod 208 is installed inside the threaded hole. The thread pitch is processed according to actual needs, so that the threaded hole can stably lock the first positioning rod 208. The bottom mold 201, mold head 202, positioning plate 20201, electric motor 203, multi-element sensor 204, micro actuator 205, isolation glass 206, threaded rod 207, first positioning rod 208, and nut 209 cooperate to form the forming mechanism 2. Specifically, the first positioning rod 208 cooperates with the sliding hole to guide the movement direction of the mold head 202, so that the mold head 202 can move vertically up and down stably. The forming mechanism 2, which is composed of various components, realizes the integrated functions of positioning, monitoring, adjustment, and fixing, ensuring that the nylon melt film is always in a precise control state during the forming process, improving the uniformity of film thickness and forming quality.

[0018] Example 2, based on Example 1, such as Figures 1-8 As shown, a baffle plate is provided at the bottom of the die head 202. The baffle plate has a U-shaped structure. A sliding groove corresponding to the baffle plate is opened at the outer periphery of the bottom die 201. The baffle plate extends into the interior of the sliding groove. The sides of the baffle plate and the sliding groove are in slight contact. The specific function is that the cooperation between the baffle plate and the sliding groove forms a sealing structure, which can effectively prevent the overflow of molten material during the melt forming process. The multi-element sensor 204, micro-actuator 205, and electric motor 203 are electrically connected according to the conventional steps. The multi-element sensor 204, micro-actuator 205, and electric motor 203 need to be connected to the controller of the nylon film manufacturing equipment body with a power cord. The controller of the body controls the multi-element sensor 204, micro-actuator 205, and electric motor 203.

A first positioning rod 208 is installed through the sliding hole on the side of the mold head 202. The bottom of the first positioning rod 208 is threaded and installed in the threaded hole of the stabilizing seat 1 to stabilize it, thus completing the positioning of the mold head 202. The clamping plate 301 is pushed to one side to compress the support spring, and the multi-element sensor 204 and the micro actuator 205 are installed in the rectangular mounting holes of the mold head 202 respectively. Then the clamping plate 301 is released, and the clamping plate 301 is reset under the support of the spring to quickly lock the multi-element sensor 204 and the micro actuator 205. Following standard electrical connection procedures, connect the terminals of the multi-element sensor 204, micro-actuator 205, and electric motor 203 to the controller of the nylon film manufacturing equipment via power cables. Control the electric motor 203 to drive the threaded rod 207 to rotate, thereby moving the die head 202 up and down. In conjunction with the multi-element sensor 204 and micro-actuator 205, control the film extrusion gap between the die head 202 and the bottom die 201. Following standard procedures, connect the connecting sleeve at the bottom of the bottom die 201 with the drainage pipe to the material storage position of the nylon film manufacturing equipment. Start the nylon film manufacturing equipment. The extrusion system delivers the molten nylon raw material to the discharge tank of the bottom die 201.
