Description

Technical Field

[0001] The invention relates to the technical field of raw material mixing equipment, and in particular to a raw material mixing device for processing degradable packaging bags. Background Art

[0002] Mixing means that various raw material components are mixed with each other under the action of external force, and the particles of various components are evenly distributed in any volume. It is an important link to ensure the quality of the raw materials and improve the effect of the raw materials. It also refers to the unit operation of using mechanical or fluid dynamic methods to disperse two or more raw materials to achieve a certain degree of uniformity. When preparing a uniform mixture, the mixing effect is measured by the degree of mixing of the mixture, that is, the uniformity achieved.

[0003] Packaging bags refer to bags used to package various supplies, which make it easy to transport and store goods during production and circulation. Degradation generally refers to the reduction of the number of carbon atoms in organic compound molecules and the reduction of molecular weight. Different scholars hold different views on degradation. One view is that degradation products must eventually be decomposed into carbon dioxide and water to be called degradation.

[0004] When the existing equipment processes the raw materials of the degradable packaging bag, the equipment is constantly rotating, and the raw materials inside are mixed evenly, but the contact area remains unchanged, so the raw materials are mixed evenly, which affects the working efficiency of the equipment. In addition, when the traditional mixing equipment mixes the raw materials, the stirring angle cannot be changed, and the direction is single, which affects the mixing efficiency of the equipment.

[0005] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0006] The object of the present invention is to provide a raw material mixing device for processing biodegradable packaging bags to solve the technical defects mentioned above. When the stirring rod reciprocates up and down, the concentric rod drives the self-locking plate to slide inside the annular tooth plate to realize the rotation of the concentric rod. At the same time, when the gear plate on the concentric rod engages with the annular tooth plate, the concentric rod realizes self-rotation, and then the concentric rod drives the stirring rod to rotate inside the connecting sleeve, thereby achieving the effect of changing the angle of the stirring blade. When the gear plate is separated from the annular tooth plate, due to the influence of the torsion spring restoring force, the stirring rod returns to its original position, thereby facilitating the changing of the stirring angle of the equipment again when engaging next time, which helps to achieve the effect of intermittently changing the angle of mixing, further improves the mixing efficiency of the equipment, and solves the existing problems of single mixing direction and fixed range.

[0014] Preferably, the method for using the raw material mixing device for processing degradable packaging bags comprises the following steps:

[0015] Step 1: When mixing the raw materials, add the raw materials into the mixing tank through the inside of the feed pipe, and then control the driving motor to work, so that the driving motor drives the reciprocating screw to rotate inside the mixing tank, and the reciprocating screw drives the moving slide plate to rotate in a circle through the hollow tube, and then the moving slide plate drives the stirring blades on the stirring rod to rotate through the connecting sleeve, so as to achieve the effect of mixing the raw materials;

[0016] Step 2: When the stirring blade rotates, it is affected by the centrifugal force, causing the stirring blade to slide outside the linkage rod, and at the same time stretching the hollow spring, thereby achieving the effect of changing the position of the stirring blade, that is, changing the stirring radius of the equipment by means of centrifugal force, which helps to change the radius of the stirring blade to improve the mixing effect of the raw materials;

[0017] Step 3: When the reciprocating screw is rotating, the reciprocating screw drives the external guide slider to reciprocate up and down inside the positioning plate. During the reciprocating movement of the guide slider, the guide slider pulls the connecting sleeve through the guide sleeve on the positioning sleeve to reciprocate up and down synchronously, so that the moving slide plate slides up and down inside the hollow tube, and then the stirring blades on the stirring rod under the connecting sleeve move synchronously, thereby achieving the effect of changing the stirring height of the equipment;

[0018] Step 4: When the stirring rod reciprocates up and down, the stirring rod drives the annular tooth plate to reciprocate up and down synchronously through the self-locking plate on the concentric rod, and causes the concentric rod to rotate. When the connecting sleeve drives the concentric rod to rotate inside the mixing tank, the concentric rod completes its self-rotation through the mutual cooperation between the gear plate and the annular tooth plate, that is, the concentric rod rotates while rotating, so that the concentric rod drives the stirring rod to rotate inside the connecting sleeve, thereby achieving the effect of changing the angle of the stirring blade, and when the gear plate and the annular tooth plate are separated, due to the influence of the torsion spring restoring force, the stirring rod returns to its original position, so that it is convenient to change the stirring angle of the equipment again when meshing next time, and further improve the mixing efficiency of the equipment, that is, the effect of improving the mixing of raw materials of the equipment is achieved by changing the stirring radius, stirring height and stirring angle.

[0019] The beneficial effects of the present invention are as follows:

[0020] (1) Due to the influence of centrifugal force, the present invention causes the stirring blade to slide outside the linkage rod and stretch the hollow spring at the same time, thereby achieving the effect of changing the position of the stirring blade, that is, changing the stirring radius of the equipment by means of centrifugal force, which helps to change the radius of the stirring blade to improve the effect of mixing the raw materials. When the reciprocating screw rotates, the movable slide plate slides up and down inside the hollow tube, thereby causing the stirring blade on the stirring rod below the connecting sleeve to move synchronously, thereby achieving the effect of changing the stirring height of the equipment, which helps to further improve the mixing effect of the equipment;

[0021] (2) When the stirring rod reciprocates up and down, the concentric rod drives the self-locking plate to slide inside the annular tooth plate to realize the rotation of the concentric rod. At the same time, when the gear plate on the concentric rod meshes with the annular tooth plate, the concentric rod realizes self-rotation, and then the concentric rod drives the stirring rod to rotate inside the connecting shaft sleeve, thereby achieving the effect of changing the stirring blade angle. When the gear plate is separated from the annular tooth plate, the stirring rod is restored to its original position due to the influence of the torsion spring restoring force, thereby facilitating the changing of the stirring angle of the equipment again when the equipment is meshed next time, which helps to achieve the effect of intermittently changing the angle of mixing and further improve the mixing efficiency of the equipment, that is, the effect of improving the mixing of raw materials of the equipment is achieved by changing the stirring radius, stirring height and stirring angle.
