Description

Technical Field

[0001] This utility model relates to the field of woven bag technology, specifically to a mixing device for producing waterproof and high-temperature resistant woven bags. Background Technology

[0002] Plastic woven bags are typically made from polypropylene and polyethylene as main raw materials. During production, the plastic matrix, inorganic fillers, interface modifiers, and processing aids are blended, then extruded at high temperatures to form a film, drawn into fibers, and woven and sewn. Calcium carbonate is a commonly used inorganic filler, which can improve the rigidity and strength of woven bags and control costs. However, inorganic fillers such as calcium carbonate have a certain degree of hygroscopicity. During storage and transportation, if the ambient humidity is high, these raw materials easily absorb moisture from the air, causing water bridges to form between particles and leading to clumping. Therefore, it is necessary to break up and stir the clumped raw materials to achieve the best mixing effect.

[0003] Existing technologies have simple mixing mechanisms and few types of mixing blades, which cannot quickly break up clumps of raw materials, resulting in reduced mixing efficiency. Utility Model Content

[0004] In order to solve the technical problems of existing mixing mechanisms being simple and having few types of mixing blades, which makes it impossible to quickly disperse clumps of raw materials and thus reduce mixing efficiency, this utility model provides a mixing device for the production of waterproof and high-temperature resistant woven bags.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for producing waterproof and high-temperature resistant woven bags, comprising: a mixing tank, a discharge pipe connected to the bottom of the mixing tank, a valve installed inside the discharge pipe, a stirring shaft rotatably connected to the bottom wall of the mixing tank, a grid sliding chamber connected to the middle of the mixing tank, a horizontally arranged vibrating grid slidably connected inside the grid sliding chamber, a rotary cutter in contact with the lower surface of the vibrating grid, the rotary cutter connected to the stirring shaft, a stirring blade connected to the lower part of the stirring shaft, a vibration structure installed on the upper part of the stirring shaft, the vibration structure being able to drive the vibrating grid to slide back and forth inside the grid sliding chamber, and a hopper connected to and connected to the top wall of the mixing tank.

[0006] Preferably, an input shaft is concentrically arranged inside the hopper, the input shaft is rotatably connected to a bearing bracket, the bearing bracket is connected to the upper surface of the hopper, and an elbow discharge pipe is rotatably connected to the top wall of the mixing tank. The upper part of the elbow discharge pipe is inserted into the hopper and is concentrically arranged with the hopper. The input shaft is connected to the inner wall of the elbow discharge pipe.

[0007] Preferably, the stirring blades include straight stirring blades and spiral stirring blades, which are alternately arranged and connected to the stirring shaft.

[0008] Preferably, the vibration structure includes a central block connected to the vibration grid. The central block has a shaped groove, and a cam is provided in the shaped groove. The cam is connected to the upper end of the stirring shaft, and the rotating cam can drive the central block to move through the shaped groove.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. After the agglomerated raw material is injected, it falls into the vibrating grid. Under the vibration of the vibrating grid, the agglomerated raw material is broken up. Some of the raw material that is not completely broken down falls and is cut and crushed by the high-speed rotating rotary cutter. Through multiple processes of crushing and cutting, the raw material is already in a broken state when it is stirred, and it can be quickly mixed with other raw materials to improve the mixing efficiency.

[0011] 2. While the material is being discharged from the elbow discharge pipe, the lower elbow rotates eccentrically, so that the raw material falls evenly into the vibrating grid, avoiding the accumulation of raw material and affecting the crushing efficiency. Attached Figure Description

[0019] The present invention will now be described in detail with reference to the accompanying drawings.

[0020] The following is in conjunction with the appendix Figure 1-4 This embodiment describes a mixing device for producing waterproof and high-temperature resistant woven bags, comprising: a mixing tank 1, a discharge pipe 2 connected to the bottom of the mixing tank 1, a valve installed in the discharge pipe 2, a stirring shaft 3 rotatably connected to the bottom wall of the mixing tank 1, a grid sliding chamber 4 connected to the middle of the mixing tank 1, a horizontally arranged vibrating grid 5 slidably connected in the grid sliding chamber 4, a rotary cutter 6 in contact with the lower surface of the vibrating grid 5, the rotary cutter 6 connected to the stirring shaft 3, a stirring blade 7 connected to the lower part of the stirring shaft 3, a vibration structure 8 provided on the upper part of the stirring shaft 3, the vibration structure 8 being able to drive the vibrating grid 5 to slide back and forth in the grid sliding chamber 4, and a hopper 9 connected and communicated to the top wall of the mixing tank 1.

[0021] The vibration structure 8 and stirring shaft 3 are activated, and the agglomerated raw materials are injected into the mixing tank 1 through the hopper 9. The agglomerated raw materials fall into the vibrating grid 5. The vibration structure 8 drives the vibrating grid 5 to slide back and forth at high frequency in the grid sliding chamber 4. Under the vibration of the vibrating grid 5, the inner wall of the vibrating grid 5 crushes the agglomerated raw materials. Some of the raw materials that are not completely crushed fall and are cut and broken by the rotary cutter 6 driven by the stirring shaft 3 at high speed. The crushed raw materials fall to the bottom of the mixing tank 1 and are stirred by the stirring blade 7 driven by the stirring shaft 3 at high speed. Through multiple processes of crushing and cutting, the raw materials are already in a broken state when they are stirred, and they are quickly mixed with other raw materials, improving the mixing efficiency.

[0022] An input shaft 10 is concentrically arranged inside the hopper 9. The input shaft 10 is rotatably connected to the bearing bracket 11.

The upper part of the bent discharge pipe 12 is inserted into the hopper 9 and is concentrically arranged with the hopper 9. The input shaft 10 is connected to the inner wall of the bent discharge pipe 12.

[0023] When feeding material, the power connected to the input shaft 10 is turned on. The input shaft 10 drives the elbow discharge pipe 12 to rotate. While the elbow discharge pipe 12 discharges material, the lower elbow rotates eccentrically, so that the raw material falls evenly into the vibrating grid 5, avoiding the accumulation of raw material and affecting the crushing efficiency.

[0024] The stirring blade 7 includes a straight stirring blade 71 and a spiral stirring blade 72, which are alternately arranged and connected to the stirring shaft 3.

[0025] The spiral stirring blade 72 lifts the raw material to the flat stirring blade 71, where it is stirred by the flat stirring blade 71, thus improving the stirring efficiency by enhancing the fluidity of the raw material.

[0026] The vibration structure 8 includes a central block 81, which is connected to the vibration grid 5. A shaped groove 82 is provided in the central block 81, and a cam 83 is provided in the shaped groove 82. The cam 83 is connected to the upper end of the stirring shaft 3. The rotating cam 83 can drive the central block 81 to move through the shaped groove 82.

[0027] The stirring shaft 3 drives the cam 83 to rotate. The cam 83 drives the central block 81 and the vibrating grid 5 to slide back and forth at high frequency in the grid sliding chamber 4 through the irregular groove 82, thereby achieving vibration.
