Description

Technical Field

[0001] This utility model relates to the field of polyester chip melting technology, specifically to an improved polyester chip screw melt extruder. Background Technology

[0002] Currently, polyester chips are used as raw materials for melt extrusion in the geotextile production field. The traditional melt extrusion equipment is also a screw extruder, which consists of a screw rotating in a heated barrel. Due to its simple structure, ease of manufacturing, high processing efficiency, and low price, it is widely used and is the most technologically mature and widely used type of extruder.

[0003] However, in existing screw extruders, the granules or raw materials sometimes stick together when the granular raw materials are poured from the feed hopper. This can easily cause blockage at the feed inlet. At the same time, the sticky raw materials can lead to incomplete melting of the granular raw materials when they are melted at high temperatures, thus affecting subsequent processing.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an improved polyester chip screw melt extruder to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] An improved polyester chip screw melt extruder includes a base and a processing box. The processing box is located on the top of the base. A feed box is provided on one side of the top of the processing box. A separation mechanism for separating polyester chips is provided in the feed box. The separation mechanism includes two sets of symmetrically arranged staggered plates. A plurality of evenly distributed rubber actuating columns are provided on the side of the two sets of staggered plates that are close to each other.

[0008] Preferably, the separation mechanism further includes a housing located inside the feed box, with vertically arranged movable columns symmetrically arranged inside the housing. The top ends of the two sets of movable columns extend to the outside of the housing and are respectively connected to the two sets of staggered plates. A sleeve block connected to the housing is movably fitted on the movable column.

[0009] Preferably, the two sets of movable columns are provided with toothed plates on one side that is close to each other, and a semi-circular toothed disc is provided on one side of the toothed plate to mesh with it. A sleeve is provided on one side of the toothed disc, and a fixed shaft that is movably connected to the housing is provided at the connection between the sleeve and the toothed disc.

[0010] Preferably, the housing is provided with symmetrically arranged gears on one side of the two sets of sleeves, and a sliding shaft is provided on one side of the gear at an eccentric position, which passes through the sleeve on one side. The sleeve is provided with a stroke hole for the sliding shaft to pass through.

[0011] Preferably, a driven gear meshes between the two sets of gears, and the gear is connected to the housing via a rotating shaft.

[0012] Preferably, the housing is located on one side inside the feed box, and one end of one of the rotating shafts is connected to the output shaft of a servo motor inside the housing.

[0013] Preferably, the rubber actuating posts on the two sets of interlaced plates are staggered.

[0014] The beneficial effects of this utility model are as follows: by setting up the separation mechanism, two sets of movable columns can alternately lift two sets of staggered plates. The staggered plates can drive several staggered rubber actuating columns to move up and down. In this way, the raw material will gradually fall down as the rubber actuating columns move up and down. The rubber actuating columns separate the granular raw materials that are stuck together, thus solving the problem of easy blockage at the feed inlet. Attached Figure Description

The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0024] According to an embodiment of the present invention, an improved polyester chip screw melt extruder is provided.

[0025] Example 1:

[0026] like Figure 1-5 As shown, the improved polyester chip screw melt extruder according to an embodiment of the present invention includes a base 1 and a processing box 2. The processing box 2 is located on the top of the base 1. A feed box 3 is provided on one side of the top of the processing box 2. A separation mechanism for separating polyester chips is provided in the feed box 3. The separation mechanism includes two sets of symmetrically arranged staggered plates 4. A plurality of evenly distributed rubber actuating columns 10 are provided on the side of the two sets of staggered plates 4 that are close to each other.

[0027] Example 2:

[0028] like Figure 1-5As shown, the separation mechanism also includes a housing 11 located inside the feed box 3. The housing 11 contains symmetrically arranged vertically positioned movable columns 12. The tops of the two sets of movable columns 12 extend outside the housing 11 and are respectively connected to the two sets of staggered plates 4. Sleeve blocks 13 connected to the housing 11 are movably fitted onto the movable columns 12. A toothed plate 14 is provided on one side of the two sets of movable columns 12 that are close to each other. A semi-circular toothed disc 15 meshes with the toothed plate 14 on one side. A sleeve 16 is provided on one side of the toothed disc 15. A fixed shaft 17 movably connected to the housing 11 is provided at the connection between the sleeve 16 and the toothed disc 15. A symmetrically arranged gear 18 is provided inside the housing 11 and on one side of the two sets of sleeves 16. A sliding shaft 19, penetrating the sleeve 16 on one side, is provided eccentrically on one side of the gear 18. A stroke hole 20 is provided on the sleeve 16 for the sliding shaft 19 to pass through.

[0029] Example 3:

[0030] like Figure 1-5 As shown, there is a driven gear 21 meshing between the two sets of gears 18. The gears 18 are connected to the housing 11 through a rotating shaft. The housing 11 is located on one side inside the feed box 3, and one end of one of the rotating shafts is connected to the output shaft of the servo motor inside the housing 11. Several rubber actuating posts 10 on the two sets of interleaved plates 4 are distributed in an interleaved manner.

[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0032] In practical applications, raw materials are fed into the upper part of the feed box 3 and gradually enter the processing box 2. The servo motor is started to drive one of the gears 18 to rotate. Gear 18 meshes with the driven gear 21 to drive the other set of gears 18 to rotate, so that the two sets of gears 18 rotate in opposite directions respectively. During the rotation of gear 18, its sliding shaft 19 makes a circular motion. The sliding shaft 19 makes a reciprocating motion in the stroke hole 20 and drives the gear disk 15 to reciprocate around the fixed shaft 17 as the axis through the sleeve 16. The gear disk 15 meshes with the gear plate 14 to drive the movable column 12 to make a reciprocating motion up and down. The two sets of movable columns 12 alternately lift the two sets of staggered plates 4. The staggered plates 4 can drive several staggered rubber actuating columns 10 to move up and down. In this way, the raw materials will gradually fall down as the rubber actuating columns 10 move up and down. The rubber actuating columns 10 separate the granular raw materials that are stuck together.

[0033] In summary, by means of the above-mentioned technical solution of this utility model, through the setting of the separation mechanism, the two sets of movable columns 12 can alternately lift the two sets of staggered plates 4. The staggered plates 4 can drive a number of staggered rubber actuating columns 10 to move up and down. In this way, the raw material will gradually fall down as the rubber actuating columns 10 move up and down. The rubber actuating columns 10 separate the granular raw materials that are stuck together, thus solving the problem of easy blockage of the feed inlet.
