Description

Technical Field

[0001] The utility model belongs to the field of dry-mix mortar packaging, and in particular relates to an automatic packaging machine for dry-mix mortar production. Background Art

[0002] Dry-mix mortar is a granular or powdered material made by physically mixing dried and sieved aggregate, inorganic binders (such as cement), and additives in a specific proportion. It is delivered to the construction site in bags or bulk and can be used directly after adding water and mixing. Dry-mix mortar is widely used in the construction industry for its bonding, cushioning, protective, and decorative properties in thin layers.

[0003] After the production of dry-mix mortar is completed, it is often necessary to pack the dry-mix mortar and transport it to the construction site. During the packing process, a large amount of fly ash will be generated when the dry-mix mortar falls from the barrel into the packing bag, resulting in waste of dry-mix mortar and chaos at the packing site. For this reason, an automatic packing machine for dry-mix mortar production is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an automatic packaging machine for dry mortar production, which solves the problems in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions:

[0006] An automatic baler for dry mortar production includes a base plate with a rotatable turntable above the base plate. A plurality of outer cylinders evenly distributed in the circumferential direction are fixed to the turntable. The outer cylinders are fitted with inner cylinders, which are sleeved with baling bags. A fixing frame is fixed to the upper end of the base plate. A mixing box is fixed to the fixing frame. A sleeve is fixed to the outlet of the mixing box. The inner diameter of the inner cylinder is equal to that of the sleeve. When the outer cylinder rotates to the position directly below the mixing box, the sleeve and the inner cylinder become coaxial.

[0007] A lifting assembly is provided directly below the mixing box. The lifting assembly includes a lifting tray. A through hole is provided at the bottom of the outer cylinder. The tray can pass through the through hole to lift the inner cylinder and make the inner cylinder contact with the lower end surface of the sleeve.

[0008] Furthermore, a rotating shaft is coaxially fixed to the lower end of the turntable, a driving motor is fixed to the upper end of the bottom plate, and a driving shaft of the driving motor is coaxially fixed to the rotating shaft.

[0009] Furthermore, a plurality of positioning holes are provided on the upper end of the turntable and are evenly distributed in the circumferential direction. The positioning holes penetrate the turntable in the vertical direction. The outer cylinder and the positioning holes cooperate with each other.

A through hole is provided on the disc, and a threaded hole is provided corresponding to the side of the positioning hole. The bolt passes through the through hole and is screwed into the threaded hole.

[0011] Furthermore, a through slot is provided on one side of the mixing box near the discharge port, the through slot passes through the side wall of the mixing box, and a sliding baffle is provided in the through slot to seal the discharge port of the mixing box.

[0012] Furthermore, a stirring assembly is provided in the mixing box, and the stirring assembly includes a rotatable rotating rod, and a plurality of stirring blades are provided circumferentially of the rotating rod.

[0014] Furthermore, two fixed plates are provided on the upper end of the base plate, the sliding plate is slidably connected to the base plate, a rotatable screw rod is provided between the two fixed plates, the screw rod passes through the sliding plate and is threadedly connected thereto.

[0015] Furthermore, the thread lead angle of the screw rod is smaller than the equivalent friction angle.

[0016] Beneficial effects of the utility model:

[0017] 1. By evenly fixing multiple outer cylinders on the circumference of the turntable, multiple inner cylinders are installed in the outer cylinders, and a packing bag is set in the inner cylinder. At the same time, a sleeve is connected to the discharge port at the lower end of the mixing box, and a jacking assembly is set at the upper end of the bottom plate. When the outer cylinder rotates to the bottom of the mixing box, the jacking assembly can lift the inner cylinder and make the inner cylinder contact with the upper end of the sleeve. The inner diameter of the inner cylinder and the sleeve are equal and coaxial, so that the dry mortar can be prevented from generating fly ash overflow when receiving the material, causing chaos on site and waste of dry mortar.
