Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] The embodiment of the present application solves the problems of poor accuracy and convenience in the mortar proportioning process by providing an automatic proportioning device, thereby realizing automatic proportioning of the mortar.

[0033] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0034] The utility model embodiment discloses an automatic proportioning device for feeding glue raw materials.

[0035] According to the attached Figure 1-5 As shown, including:

[0036] The weighing unit comprises a bracket 1 , a powder scale 101 arranged on the bracket 1 , and a control valve 102 arranged at the bottom end of the powder scale 101 .

[0037] The material holding unit includes a first material holding barrel 2 and a second material holding barrel 3. The bottom ends of the first material holding barrel 2 and the second material holding barrel 3 are connected to the weighing unit. The bottom end face of the first material holding barrel 2 is provided with a first unloading valve 201. One end of the first unloading valve 201 is provided with a group of conveying pipes 4 connected to the inside of the powder scale 101. The bottom end face of the second material holding barrel 3 is provided with a second unloading valve 301. One end of the second unloading valve 301 is provided with another group of conveying pipes 4 connected to the inside of the powder scale 101. The first material holding barrel 2 and the second material holding barrel 3 are used for receiving different mortar raw materials. In addition, the number of material holding barrels can be increased according to actual needs.

[0038] The conveying unit includes a conveying pipe 4 connected to the control valve 102 and an automatic feeding pump 5 connected to the conveying pipe 4 for automatically feeding powder.

[0039] The weighing unit, the material holding unit and the conveying unit constitute a powder vacuum weighing system with model number zks-1---ZKS-20-5. When in use, the amount of raw materials to be added is first set according to the formula, so that the raw materials inside the first material holding barrel 2 and the second material holding barrel 3 can be subsequently fed to the inside of the powder scale 101 through a group of conveying pipes 4 through the PLC control system, so that the powder scale 101 weighs the weight of the powder raw materials. After the weighing is completed, the control valve 102 is automatically opened, so that at this time, under the extraction action of the automatic feeding pump 5, the weighed powder raw materials are moved through the conveying pipe 4 to the inside of the stirring device connected to one end of the automatic feeding pump 5.

[0040] An anti-caking mechanism 6 is arranged between the weighing unit and the conveying unit. The anti-caking mechanism 6 can prevent agglomerated powder from directly entering the automatic feeding pump 5 and the interior of the stirring device. The anti-caking mechanism 6 includes a processing cylinder 601. The outer wall of the processing cylinder 601 is fixedly connected to one end of the conveying pipe 4.

A positioning seat 605 is fixedly connected to the inner bottom of the processing cylinder 601. The bottom end of the movable rod 603 is clamped and arranged inside the positioning seat 605. After the automatic feeding pump 5 is turned on, it will form a suction force, so that under the action of the external suction force, the multiple groups of crushing knives 604 rotate inside the processing cylinder 601, and then the powder raw materials entering the processing cylinder 601 are crushed.

[0041] The auxiliary component 606 is used to drive the crushing knife 604 to crush the powder with the help of the external force generated by the automatic feeding pump 5. The auxiliary component 606 includes a connecting hole 6061, and the connecting hole 6061 is opened on the outer wall of the processing cylinder 601. The processing cylinder 601 is connected with the interior of the conveying pipe 4 through the connecting hole 6061. A plurality of groups of hollow plates 6062 are fixedly arranged on the outer wall of the movable rod 603, and the positions of the hollow plates 6062 and the connecting holes 6061 correspond, so that the external force generated after the automatic feeding pump 5 is turned on will directly act on the hollow plate 6062, thereby driving the crushing knife 604 coaxially arranged with the hollow plate 6062 to rotate.

[0042] A locking assembly 607 is arranged between the processing cylinder 601 and the cylinder cover 602, and the locking assembly 607 includes a clamping block 6071 and a clamping seat 6072. The clamping block 6071 and the clamping seat 6072 are respectively fixedly connected to the outer walls of the cylinder cover 602 and the processing cylinder 601, and the clamping block 6071 and the clamping seat 6072 are clamped together. The locking screw 6073 is used for locking between the clamping block 6071 and the clamping seat 6072, and the locking screw 6073 is rotatably arranged on the outer wall of the clamping seat 6072.

[0043] The automatic proportioning device for feeding the mortar raw materials, through the automatic feeding pump, weighing unit, PLC control system and anti-caking mechanism 6, enables the proportioning device to set the required amount of raw materials to be added according to the requirements of the formula, thereby realizing automatic feeding into the mixing equipment, and the feeding will not cause blockage inside the proportioning device, effectively improving the feeding speed, reducing the batch quality risk caused by deviations caused by human operation, reducing labor intensity, and being able to freely switch between different formulas, with good practicality.

[0044] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
