Problems solved by technology

[0003] In order to improve production efficiency, the factory has also improved the feeding process. For example, in order to avoid multiple feedings, a large batch of one-time input will be used, which will easily lead to the possibility of blocking the feeding port. The current feeding device It will be equipped with transmission devices such as screw rods. Although this type of structure can also play a dredging effect when used, but when facing non-granular raw materials, the effect is relatively subtle and the dredging effect is poor. In addition, large-scale During production operations, the motor works uninterruptedly, which makes it unable to dissipate heat effectively, and the probability of motor damage is high

Embodiment 1

[0046] combine Figure 1-8As shown, a screw extruder for the production of plastic woven bags provided by the present invention includes a basic module 100, an anti-blocking module 200, an anti-blocking module 200 and a cooling module 400, and includes a base 110, which is used to carry out the overall structure. Support and connection, so that the overall structure of the equipment is more precise, reducing its space occupancy, the basic module 100 is installed on the top of the base 110 and the heating cylinder 120 is symmetrical about the vertical center line of the base 110, the heating cylinder 120 The cylinder 130 is used to melt the raw material and prepare for the extrusion molding of the raw material. It is located between the heating cylinder 120 of the screw. The cylinder 130 plays the role of raw material transmission and supporting the hopper 140. It is sleeved on the outside of the cylinder 130 The hopper 140, the transmission frame 150 connected between the heat...

Embodiment 2

[0056] combine Figure 1-3 and Figure 8 As shown, on the basis of Embodiment 1, the plastic woven bag production screw extruder also includes a matching module 500, including a cylindrical cavity 510 opened at the bottom of the connecting piece 320 and a cylindrical cavity 510 opened at the bottom of the connecting piece 320. The oblique openings 520 on both sides of the 320 and symmetrical to the cylindrical cavity 510 adopt this structural design, the connecting piece 320 can be separated from the connecting piece 320 and can be connected, and the mobility is good.

Embodiment 3

[0058] combine figure 1 , 3 and Figure 4 As shown, in the above embodiment, a one-way valve is installed on the outlet pipe 430, the two circulating water pipes 450 are located between the two heating cylinders 120 and the outer wall is in contact with the biaxial motor 270, and a one-way valve is set. The valve prevents liquid water from flowing back.

[0059] The working principle and application process of the present invention: in the initial state, the hopper 140 is filled with raw materials. When the present invention is put into practical use, the biaxial motor 270 is started, and the biaxial motor 270 drives the cam 280 to rotate. The support 250 is lifted upwards, and then the support 250 drives the rod body 210 to move upward through the U-shaped frame 240. During the period when the protruding part of the cam 280 is in contact with the bottom of the support 250, the first spring 260 shrinks under force, and then the rod body 210 is inserted into the connector 320...

Abstract

The invention discloses a screw extruder for plastic woven bag production. The screw extruder comprises a basic module, an anti-blocking module, an adjusting module and a cooling module, The basic module comprises a base, heating cylinders, a cylinder body and a hopper, wherein the heating cylinders are mounted at the top of the base and are symmetrical about the vertical center line of the base, the cylinder body is positioned between the heating cylinders, and the hopper is connected to the outer side of the cylinder body in a sleeving manner. According to the screw extruder, a double-shaft motor drives a cam to rotate, a support is jacked upwards every time the cam rotates by a circle, the support drives a rod body to move upwards through a U-shaped frame, a first spring of the cam is stressed and contracted, then the rod body is inserted into a connecting piece, when the protruding portion of the cam faces downwards, the first spring rebounds and then drives the rod body to descend through the support and the U-shaped frame, then plate bodies on the two sides of the rod body are inserted into inclined openings and are opened outwards, elastic ropes pull the plate bodies, the plate bodies pull the connecting piece to move downwards, and therefore raw materials in the hopper are extruded downwards, and the dredging effect is good.

Description

technical field [0001] The invention relates to the technical field of plastic woven bag production, in particular to a screw extruder for plastic woven bag production. Background technique [0002] Woven bag, also known as snakeskin bag. It is a kind of plastic bag, used for packaging, and its raw materials are generally various chemical plastic materials such as polyethylene and polypropylene. The main raw material for foreign production is polyethylene, and the domestic production is mainly polypropylene, which is a thermoplastic resin obtained by polymerization of ethylene. Products with different densities can be obtained by using different production methods. Polyethylene can be processed by general thermoplastic molding methods (see plastic processing). It has a wide range of uses, mainly used to manufacture films, containers, pipes, monofilaments, wires and cables, daily necessities, etc., and can be used as high-frequency insulating materials for TVs, radars, etc...
