A sheath material extrusion molding machine for elevator compensation chain and use method thereof

Abstract

The invention discloses a sheath material extrusion molding machine for an elevator compensation chain and a use method thereof. The invention relates to the technical field of plastic molding. In the existing extruder, since the sheath material is hollow, during the extrusion process, when the raw material is molded, there is a certain gap inside due to air, which causes the surface of the raw material to be concave during the extrusion molding process, resulting in uneven thickness of the sheath material. Through the action of an elastic adjustment plate, the slip ring always extrudes the raw material to be extruded during the extrusion molding process, avoiding the presence of air gaps in the raw material during the extrusion process, causing the surface of the extruded sheath material to be concave, and ensuring the uniform thickness of the sheath material during the extrusion molding process. At the same time, by arranging a retaining ring, the raw material is blocked to a certain extent before extrusion molding, so that the raw material is extruded after being gathered to a certain extent, avoiding the intermittent forward extrusion of the raw material.

The output end of the machine 5 is fixedly connected, and the stirring component 32 includes a stirring chamber 321. The top of the stirring chamber 321 is fixedly connected to the bottom of the rotating shaft 31. The gap between the outer surface of the stirring chamber 321 and the inner wall of the hot melt barrel 33 gradually decreases from top to bottom. During the sliding process, the particles contact the inner wall of the hot melt barrel 33, heating the raw material particles, causing the raw material particles to gradually melt. After hot melting, the raw material particles pass through the gap and fall into the bottom and enter the molding mechanism 2.

[0052] The outer surface of the connecting column 326 is fixedly connected with a curved plate 323, and the curved plate 323 is symmetrically arranged on the outer surface of the connecting column 326. The curved plate 323 is an elastic metal plate. The end of the curved plate 323 away from the connecting column 326 is fixedly connected with a limiting plate 325.

[0053] The third embodiment is based on the first and second embodiments. Figures 9 to 11As shown, the screening mechanism 4 includes a screen cylinder 41, the bottom of which is fixedly connected to the top of the hot melt barrel 33 by rivets, the inner wall of the screen cylinder 41 is slidably connected with a screen plate 44, the top of the screen cylinder 41 is poured into the screen cylinder 41, and the raw material particles are screened through the screen holes on the surface of the screen plate 44, the inner wall of the screen plate 44 is slidably connected with a slide cylinder 45, the bottom of the slide cylinder 45 is fixedly connected with a bottom ring 47, and the bottom of the bottom ring 47 is fixedly connected with an inclined slide plate 43, the screened particles pass through the screen plate 44 and fall onto the top surface of the inclined slide plate 43, the falling speed of the raw material particles is slowed down by the inclined slide plate 43, and at the same time The top inclined slide plate 43 of the hot melt mechanism 3 is symmetrically installed at the bottom of the bottom ring 47 so that the raw material particles fall evenly into the hot melt mechanism 3. The bottom of the bottom ring 47 is fitted with a limiting ring 42. The inner wall of the limiting ring 42 is fixedly connected to the outer surface of the rotating shaft 31. The top of the bottom ring 47 is fixedly connected with an elastic plate 46. The elastic plate 46 is symmetrically installed at the top of the bottom ring 47. The elastic plate 46 is an elastic metal plate. When the raw material particles are poured into the impact screen plate 44, the impact force forces the elastic plate 46 to deform, so that the screen plate 44 slides down on the surface of the slide cylinder 45 to buffer the impact force. The top of the elastic plate 46 is fixedly connected to the bottom of the screen plate 44.

[0054] A method for using a sheath material extrusion molding machine for an elevator compensation chain comprises the following steps:

[0055] S1, material screening, workers pour the granular raw materials from the top of the screening mechanism 4, and the large debris in the raw materials is screened through the screening mechanism 4;

[0056] S2, hot melting of raw materials, the electric heating tube 13 is energized to heat the hot melting mechanism 3, so that the screened raw materials enter the hot melting mechanism 3 and are heated and melted;

[0057] S2, raw material extrusion, the hot-melted raw material falls into the extrusion bin 201 of the molding mechanism 2 under the action of gravity, and the extrusion screw 202 is driven by the screw motor 6 to rotate to extrude the raw material;

[0058] S4, discharging and molding. During the extrusion of the raw materials, the inner ring 212 and the outer ring 204 cooperate with each other to make the raw materials squeeze out from the gap between the inner ring 212 and the outer ring 204 to form a tube sleeve.

[0059] When in use, workers pour plastic raw material particles from the top of the screening mechanism 4 so that the raw materials are screened and impurities and lumps in the raw materials are screened out. The screened particles fall into the hot melt mechanism 3, and the electric heating tube 13 is energized to heat the hot melt mechanism 3 to melt the raw material particles falling into the hot melt mechanism 3. The melted raw material falls into the molding mechanism 2 under the action of gravity, and is extruded and molded by the molding mechanism 2 to form a pipe sleeve product.

[0060] When the raw material is poured from the screening mechanism 4, it is poured from the top of the screen cylinder 41 in the screening mechanism 4. After being poured into the screen cylinder 41, the raw material particles are screened through the screen holes on the surface of the screen plate 44. When the raw material particles are poured into the impact screen plate 44, the impact force forces the elastic plate 46 to deform, so that the screen plate 44 slides downward on the surface of the slide cylinder 45 to buffer the impact force. At the same time, the screened particles pass through the screen plate 44 and fall onto the top surface of the inclined slide plate 43. The inclined slide plate 43 slows down the falling speed of the raw material particles, and at the same time, the raw material particles fall evenly onto the top of the hot melt mechanism 3.

[0061] When the raw material falls into the hot melt mechanism 3, the electric heating tube 13 heats the hot melt barrel 33 in the hot melt mechanism 3, and the raw material particles fall into the top of the stirring bin 321 in the stirring assembly 32, and slide down from the top of the stirring bin 321 to the surroundings, so that the raw material particles slide down from the gap between the stirring bin 321 and the hot melt barrel 33. In the process of sliding, the particles contact the inner wall of the hot melt barrel 33, and the raw material particles are heated, so that the raw material particles are gradually melted, and after hot melting, they pass through the gap and fall to the bottom and enter the molding mechanism 2.

[0062] As the raw material particles gradually melt and move downward, the rotating shaft 31 drives the stirring chamber 321 to rotate, which causes the stirring chamber 321 to drive the slide plate 324 to rotate. The slide plate 324 drives the scraper block 322 to scrape the inner wall of the hot melt barrel 33, thereby scraping the hot-melted raw material particles in the gap, so that the raw material particles rotate while hot-melting, and pass through the gradually decreasing gap after hot-melting.

[0063] After the raw material is hot-melted, it falls into the molding mechanism 2, and the raw material enters the extrusion bin 201 of the molding mechanism 2. The extrusion screw 202 is driven to rotate by the screw motor 6, so that the extrusion screw 202 drives the raw material particles entering the extrusion bin 201 to move toward one end of the fixed cylinder 209. In the process of driving the raw material to move, the extrusion screw 202 also stirs and mixes the raw material.

[0064] During the extrusion molding process of the raw materials, when the raw materials gradually gather towards the fixed cylinder 209 after hot melting, the raw materials gather inside the fixed cylinder 209, and the raw materials are first blocked by the retaining ring 210. When the raw materials gather to a certain extent, the pressure forces the raw materials to turn over the retaining ring 210, so that the raw materials are extruded through the gap between the outer ring 204 and the inner ring 212. During the extrusion process, when there are gaps in the raw materials, the elastic deformation of the adjustment plate 207 drives the slip ring 208 to slide, squeeze the raw materials, fill the gaps in the raw materials, and extrude the raw materials evenly.

[0065] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
