Description

Technical Field

[0001] This invention belongs to the field of cable production technology, and in particular relates to an intelligent control system for extrusion processes based on cable resistance prediction. Background Technology

[0002] Extrusion is a technology that uses mechanical force to continuously form materials through a die of a specific shape under high temperature and high pressure. After the materials are mixed and prepared in the barrel, they are conveyed forward by the rotating screw. At the same time, the materials are gradually melted and plasticized by the combined action of the heating device outside the barrel and the shear heat generated by the screw rotation. The fully plasticized melt is extruded through the die head under the pressure of the screw, and then rapidly cooled and solidified by the sizing device. Finally, the traction device provides a precise and stable traction force to pull the product out at a uniform speed, and the continuous product is cut into cable products of standard length by the fixed length cutting device.

[0003] In the field of cable manufacturing, existing cable resistance prediction technology is mainly based on the theoretical model of conductor material resistivity formula combined with real-time process parameters. It also uses machine learning methods such as random forest to integrate production data and environmental factors for error compensation to improve prediction accuracy, thus constructing a process-resistance coupling model. This method significantly improves the accuracy of cable resistance prediction and provides an effective means for intelligent control of extrusion processes.

[0004] A Chinese patent with publication number CN114474663B discloses a low-smoke halogen-free flame-retardant cable jacket forming device. In the process of mixing and formulating the extruded material in the barrel, the mixing of different materials is achieved by controlling the single rotation of the stirring plate by the driving rod. Moreover, this mixing and formulating method mainly achieves the mixing of materials in the circumferential direction, thereby reducing the efficiency of mixing and formulating different materials.

The through-and-close assembly includes a through-and-close plate rotatably fitted inside a hollow spherical cover. A linkage rod penetrating the extrusion control console is fixed to the top of the through-and-close plate. A one-way rotating plate is fixed to the top of the linkage rod. Baffle one and baffle two are respectively in close contact with the corresponding one-way rotating plates.

[0014] The present invention has the following beneficial effects: 1. When the auger shaft drives the auger blades to rotate clockwise, the clockwise rotating auger blades gradually transport the raw materials at the bottom of the material preparation box upwards along the lower port of the guide tube. A portion of the upwardly transported raw materials flows out along the radially arranged mixing holes at different heights, thereby achieving radial mixing of the raw materials inside the material preparation box. The other upwardly transported raw materials flow out through the upper port of the guide tube and return to the material preparation box, thereby achieving axial mixing of the raw materials inside the material preparation box. While controlling the auger blades to rotate clockwise, the guide tubes are driven to rotate counterclockwise. Under the combined action of the clockwise rotation of the auger blades and the counterclockwise rotation of the guide tubes, the lower layer of raw materials in the material preparation box can be continuously transported to the upper layer of raw materials to improve the mixing efficiency. The stirring component composed of the wall-scraping mixing plate and the circumferential mixing plate can fully mix the different raw materials in the material preparation box. Thus, the mixing effect and mixing efficiency of the raw materials in the material preparation box are greatly improved through multi-directional mixing.

[0015] 2. This invention controls the auger blades to rotate clockwise by a drive motor, which simultaneously drives the entire multi-point actuation assembly to rotate clockwise. During this process, the intermittent squeezing action of the unidirectional actuation plate on the unidirectional rotating plate achieves the intermittent opening and closing of each through-and-close plate, so that all materials in the internal mixer and the material tank are intermittently transported to the material preparation box. The materials transported to the inner wall of the material preparation box are fully mixed under the action of the stirring component composed of the wall scraping mixing plate and the circumferential mixing plate. While controlling the auger shaft to drive the auger blades to rotate counterclockwise, the entire multi-point actuation assembly is driven to rotate counterclockwise synchronously. During this process, the unidirectional actuation plates on the entire multi-point actuation assembly will not hinder the rotation of the auger blades. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] For a specific implementation example, please refer to Implementation Example 1. Figures 1-8 The present invention is an intelligent control system for extrusion process based on cable resistance prediction, including an extrusion control mechanism 1 and a multi-directional mixing mechanism 2 disposed therein; wherein, the extrusion control mechanism 1 includes a material preparation box 101, the bottom of the material preparation box 101 is connected to an outlet pipe 102, and the bottom of the outlet pipe 102 is connected to an extrusion molding part (the extrusion molding part is a common raw material extrusion structure in the cable sheath production process in the prior art).

[0028] The multi-directional mixing mechanism 2 consists of a concentrically arranged and counter-rotating screw conveyor assembly and a multi-directional mixing assembly. It should be noted that the screw conveyor assembly and the multi-directional mixing assembly always rotate synchronously in opposite directions. The screw conveyor assembly extends from the material preparation box 101 to the outlet pipe 102. The multi-directional mixing assembly is located in the material preparation box 101 and is used to realize the mixing and preparation of different materials in the circumferential, radial and axial directions, so as to improve the mixing and preparation effect of different materials in the material preparation box 101.

[0029] In this embodiment of the invention, such as Figure 4As shown, the extrusion control mechanism 1 also includes an extrusion control console 103. A U-shaped support frame 104 is fixed at the top center of the extrusion control console 103. A drive motor 105 is installed on the top of the U-shaped support frame 104. A turntable cavity 106 coaxial with the drive motor 105 is provided on the top of the extrusion control console 103. A material preparation box 101 is fixedly installed at the bottom of the extrusion control console 103. The turntable cavity 106 and the material preparation box 101 are connected through a shaft hole 107. The turntable cavity 106, the shaft hole 107 and the material preparation box 101 are concentrically arranged.

[0030] In this embodiment of the invention, such as Figure 3 and Figure 5 As shown, the extrusion molding section includes an extrusion channel 108 connected to the bottom of the outlet pipe 102 (a heating device is installed outside the extrusion channel 108 to heat the extruded material flowing through the extrusion channel 108). An outlet 109 is installed at the end of the extrusion channel 108 away from the outlet pipe 102. The extruded material that has been mixed and formulated in the outlet pipe 102 is pressurized and flows along the extrusion channel 108, and is extruded and shaped through the outlet 109. The shaped product can be cooled and shaped by subsequent cooling and shaping equipment. A guide plate for guiding flow is fixed at the bottom of the outlet pipe 102 (not shown in the figure). After being pressurized, the extruded material that has been mixed and formulated in the outlet pipe 102 is guided by the guide plate and enters the extrusion channel 108. The top of the extrusion control console 103 is equipped with a mixer 110 and a feed tank 111 located on both sides of the U-shaped support frame 104. It should be noted that the internal mixer 110 is existing technology, used for crushing and mixing EVA / PE granules. The feed tank 111 is used to store additives and flame retardants, therefore the structure of the internal mixer 110 will not be described in detail. The material preparation tank 101 has two symmetrically arranged guide pipes 112 connected to its periphery. The internal mixer 110 and the feed tank 111 are respectively connected to the corresponding guide pipes 112. A hollow spherical cover 113 is fixed on the guide pipe 112 and connected to it. When the hollow spherical cover 113 on the guide pipe 112 is in the open state, the materials in the internal mixer 110 and the feed tank 111 can flow into the material preparation tank 101. The top of the extrusion control console 103 is fixed with a baffle 114 close to the internal mixer 110 and a baffle 215 close to the feed tank 111 (the specific positions of the baffle 114 and the baffle 215 are as follows). Figure 3 (As shown).

[0031] In this embodiment of the invention, such as Figure 6As shown, the screw conveyor assembly includes an auger shaft 201 that passes through a shaft hole 107 and is connected to the output shaft of a drive motor 105 (i.e., the rotation control of the auger shaft 201 is achieved through the drive motor 105). An auger plate 202 is fixedly installed on the circumferential side of the auger shaft 201. The bottom of the auger plate 202 extends into the outlet pipe 102 and is close to the inclined guide plate. A bevel gear 203 is fixedly installed on the circumferential side of the auger shaft 201. A bevel gear 116 is connected to the inner wall of the shaft hole 107 through a rotating shaft (the rotating shaft is fixedly connected to the bevel gear 116). The bevel gear 116 meshes with the bevel gear 203 above it for transmission.

[0032] Furthermore, the multi-directional mixing assembly includes a guide tube 204 sleeved on the outside of the auger plate 202. The top of the guide tube 204 is connected to a support ring 205 through a fixing plate. The support ring 205 is rotatably disposed at the bottom of the extrusion control console 103, that is, the extrusion control console 103 supports the entire multi-directional mixing assembly. A bevel gear 206 is fixedly installed on the top of the support ring 205, located inside the shaft hole 107. The bevel gear 216 meshes with the bevel gear 206 below it, that is, the synchronous linkage between the multi-directional mixing component and the screw conveyor component is realized through the transmission cooperation between the bevel gear 1203, the bevel gear 216 and the bevel gear 206. The circumferential side of the guide cylinder 204 is provided with several radial mixing holes 207. The radial mixing of materials is realized through the circumferentially arranged radial mixing holes 207. Several scraper mixing plates 208 are slidably provided on the inner wall of the material preparation box 101. The scraper mixing plates 208 are connected to the guide cylinder 204 through the circumferential mixing plate 209. The stirring component composed of the scraper mixing plate 208 and the circumferential mixing plate 209 can fully mix the different raw materials in the material preparation box 101.

[0033] When the drive motor 105 controls the auger shaft 201 to drive the auger plate 202 to rotate clockwise (as shown in the image), Figure 3As shown), the clockwise rotating auger plate 202 gradually conveys the raw material at the bottom of the material preparation box 101 upwards along the lower port of the guide tube 204. A portion of the upward-conveyed raw material flows out through the radially arranged mixing holes 207 at different heights, achieving radial mixing of the raw material inside the material preparation box 101. The remaining upward-conveyed raw material flows out through the upper port of the guide tube 204 and returns to the material preparation box 101, achieving axial mixing of the raw material inside the material preparation box 101 (i.e., continuously conveying the lower layer of raw material to the upper layer of raw material in the material preparation box 101; this cycle greatly improves the mixing effect). During this process, the clockwise rotation of the auger plate 202 prevents the raw material in the material preparation box 101 from flowing downwards along the outlet pipe 102. The first bevel gear 203, which rotates synchronously with the auger shaft 201, drives the second bevel gear 116 to rotate. Under the transmission action of the second bevel gear 116, the third bevel gear 206 rotates counterclockwise. Thus, while controlling the clockwise rotation of the auger plate 202, the guide cylinder 204 is driven to rotate counterclockwise. Under the combined action of the clockwise rotation of the auger plate 202 and the counterclockwise rotation of the guide cylinder 204, the lower layer of raw materials in the material preparation box 101 can be continuously transported to the upper layer of raw materials to improve the mixing efficiency. The stirring component composed of the scraper mixing plate 208 and the circumferential mixing plate 209 can fully mix the different raw materials in the material preparation box 101. Thus, the mixing effect and mixing efficiency of the raw materials in the material preparation box 101 are greatly improved by the above-mentioned multi-directional mixing method.

[0034] After the different raw materials in the material preparation box 101 are mixed and prepared, the drive motor 105 controls the auger shaft 201 to drive the auger plate 202 to rotate counterclockwise. Under the action of the auger plate 202, the extruded raw materials in the material preparation box 101 are gradually transported to the outlet pipe 102. The extruded material that has been mixed and prepared in the outlet pipe 102 is pressurized and guided by the inclined guide plate into the extrusion channel 108, and is extruded and formed through the discharge port 109. The formed product can be cooled and shaped by the subsequent cooling and shaping equipment, thus realizing the extrusion production of cable sheaths.

[0035] For a specific embodiment two, please refer to Figure 2 , Figure 7 and Figure 8 The extrusion control console 103 is equipped with a one-to-one opening and closing assembly 3 corresponding to the internal mixer 110 and the feed tank 111. The opening and closing assembly 3 includes an opening and closing plate 301 rotatably fitted inside the hollow spherical cover 113. A linkage rod 302 is fixedly fixed to the top of the opening and closing plate 301, penetrating the extrusion control console 103. The linkage rod 302 is rotatably connected to the extrusion control console 103. A one-way rotating plate 303 is fixedly installed on the top of the linkage rod 302. Baffle 1 114 and baffle 2 115 are respectively in close contact with the corresponding one-way rotating plate 303 (e.g., Figure 3As shown), a torsion spring cover 304 fixed to the bottom of the extrusion control console 103 is sleeved on the outer side of the linkage rod 302. A reset torsion spring connected to the linkage rod 302 is provided inside the torsion spring cover 304 (this is prior art and will not be described in detail here). Figure 3 As shown, in the initial state, baffle 114 is tightly fitted with the corresponding one-way rotating plate 303, and baffle 215 is also tightly fitted with the corresponding one-way rotating plate 303.

[0036] Furthermore, a multi-point toggle assembly 4 is provided below the U-shaped support frame 104. The multi-point toggle assembly 4 includes a turntable body 401 rotatably fitted inside the turntable cavity 106. A sealed cover 402 coaxial with the top of the turntable body 401 is fixed thereon. The bottom of the turntable body 401 is provided with a shaft hole 2 communicating with the sealed cover 402. The output shaft of the drive motor 105 extends to the inside of the sealed cover 402 and the two are fixedly connected. In this way, the drive motor 105 can control the auger plate 202 to rotate while driving the entire multi-point toggle assembly 4 to rotate synchronously.

[0037] Furthermore, the top of the turntable body 401 is provided with a plurality of one-way deflecting plates 403 that are rotatably connected thereto. A stop block 404 fixed to the turntable body 401 is attached to one side of the one-way deflecting plate 403. A connecting plate 405 corresponding to the one-way deflecting plate 403 is fixed on the top of the turntable body 401. The connecting plate 405 is connected to the corresponding one-way deflecting plate 403 through an arc-shaped elastic element 406 (it should be noted that the stop block 404 is arranged relative to the compression direction of the corresponding arc-shaped elastic element 406, that is, each one-way deflecting plate 403 can only rotate in the compression direction of the arc-shaped elastic element 406).

[0038] like Figure 3As shown, while the auger plate 202 is controlled to rotate clockwise by the drive motor 105, the entire multi-point actuation assembly 4 is driven to rotate clockwise synchronously. When one one-way actuation plate 403 contacts the one-way rotating plate 303 at the position of the internal mixer 110, the other one-way actuation plate 403 just contacts the one-way rotating plate 303 at the position of the feed tank 111. As the turntable 401 continues to rotate clockwise, the one-way actuation plates 403 on it are limited by the corresponding stops 404, so that the one-way actuation plates 403 rotating clockwise with the turntable 401 cannot rotate on their own. In this way, the one-way actuation plates 403 can apply a pushing force to the one-way rotating plate 303 at the position of the internal mixer 110 and the one-way rotating plate 303 at the position of the feed tank 111 through the one-way actuation plates 403. When the one-way rotating plate 303 rotates, the through-and-close plates 301 inside each hollow spherical cover 113 gradually rotate and open. The materials in the internal mixer 110 and the feed tank 111 flow into the inner wall of the material preparation box 101 along the feed pipe 112. When the one-way actuating plate 403 disengages from the one-way rotating plate 303, the through-and-close plates 301 are reset and returned to the closed state under the action of the reset torsion spring. The subsequent one-way actuating plate 403 intermittently opens and closes the through-and-close plates 301 as the turntable body 401 rotates clockwise. In this way, all the materials in the internal mixer 110 and the feed tank 111 are intermittently transported to the material preparation box 101. The materials transported to the inner wall of the material preparation box 101 are fully mixed under the action of the stirring components composed of the wall scraping mixing plate 208 and the circumferential mixing plate 209.

[0039] After the different raw materials in the material preparation box 101 are mixed and prepared, the drive motor 105 controls the auger shaft 201 to drive the auger plate 202 to rotate counterclockwise, while simultaneously driving the entire multi-point actuation assembly 4 to rotate counterclockwise. Under the action of the auger plate 202, the extruded raw materials in the material preparation box 101 are gradually transported to the outlet pipe 102. During this process, the one-way actuation plates 403 that rotate counterclockwise with the turntable body 401 are not limited, so that when the one-way actuation plate 403 contacts the one-way rotating plate 303, it begins to gradually compress the arc-shaped elastic element 406 and rotates. The one-way rotating plate 303 at the position of the internal mixer 110... 3. Due to the obstruction of baffle 114, the unidirectional rotating plate 303 at the position of material tank 111 cannot rotate. At the same time, due to the obstruction of baffle 215, the unidirectional rotating plate 303 at the position of material tank 111 cannot rotate. This ensures that while controlling the auger shaft 201 to drive the auger plate 202 to rotate counterclockwise, it will not be hindered by the movement of each unidirectional rotating plate 403 on the entire multi-point toggle assembly 4. After the unidirectional rotating plate 403 is disengaged from the unidirectional rotating plate 303, the unidirectional rotating plate 403 can be reset by the compressed arc-shaped elastic element 406, so that each unidirectional rotating plate 403 presses against the corresponding stop 404 again.
