[0022] The present invention will be further described below in conjunction with the drawings and specific embodiments:

[0023] Such as figure 1 The dry powder mortar packaging machine shown includes a frame 1 and a shut-off fan 2. A vertical feeding channel 3 is provided in the frame. The upper end of the feeding channel is connected with the discharge port of the shut-off blower. The bin 4 is connected, the lower end of the feeding channel 3 is provided with a closed baffle 5, the lower end of the feeding channel is provided with a discharging tube 6, the outer end of the discharging tube is provided with a discharging nozzle 7, and the lower end of the feeding channel is provided with a horizontal Rotating shaft 8, the left end of the rotating shaft extends out of the feeding channel and is rotatably connected with the rotating shaft fixing seat 81, the right end of the rotating shaft extends into the discharge pipe and is coaxially distributed with the discharge pipe. The bottom of the frame 1 is provided with a motor 9 connected to the motor There is a motor controller, the gray box 14 is provided under the shaft fixing seat 81, and the motor is located directly under the gray box; figure 2 As shown, the upper side of the frame is also provided with a control box 10, the motor and the left end of the rotating shaft are equipped with a pulley, the motor is connected to the rotating shaft through a belt, and the rotating shaft is also provided with a spiral belt 11, and the outside of the frame is located below the discharge nozzle There are also an electronic scale 12 and a bag support frame 13 arranged above the electronic scale. The electronic scale and the motor controller are connected to the control box; the bag support frame 13 includes a support rod 131, a support seat 132, and a bag support plate 133, The support rod is vertically and fixedly connected with the top surface of the electronic scale 12, the upper end of the support rod is softly connected with the side of the frame, the support base is fixedly connected with the support rod, and the middle part of the bag pallet is rotatably connected with the support base. The outer end and the lower end of the support base are connected by an elastic telescopic rod 134.

[0024] Such as figure 1 with image 3 As shown, the outer diameter of the spiral belt 11 gradually increases from the end of the discharge nozzle to the end of the rotating shaft fixing seat. The baffle 5 is an arc-shaped plate and is distributed obliquely along the outer diameter of the spiral belt. The baffle 5 is also provided with maintenance Port 19, an inspection port cover 20 is provided on the inspection port; a flexible hose 67 is arranged between the discharge nozzle 7 and the discharge pipe 6, and both ends of the flexible hose are connected to the discharge nozzle and the discharge pipe through a clamp 68 respectively After the shut-off fan and the motor are started, the dry mortar enters the shut-off fan from the silo and then falls into the feeding channel. The rotating shaft drives the spiral belt to rotate. The dry mortar enters the discharge pipe along the spiral belt from the bottom of the feeding channel, and finally from the discharge nozzle In the feeding process, the dry mortar will circulate and stir around the shaft as the spiral belt rotates. At the same time, the diameter of the left end of the spiral belt is large and the diameter of the right end is small. Therefore, when the dry mortar moves from the left end to the right end , There is a quantity difference, the excess dry mortar will fall back to the bottom of the feeding channel along the inclined surface of the baffle, and then will be sent into the discharge pipe again along with the falling material, so as to realize the axial circulation stirring. The dry powder mortar in the medium has been mixed and stirred before entering the silo. At this time, the mixing and stirring is a large amount of mixing together, and a small amount of side feeding is performed in the feeding channel, which is equivalent to a small batch of secondary stirring, and the mixing effect is good. The various particle components in the dry powder mortar are stirred more evenly, which improves the quality of the dry powder mortar; the material bag is sleeved on the discharge nozzle, and the flexible hose connection can prevent the vibration of the frame from being transmitted to the discharge nozzle, improving the weight measurement of the electronic scale Accuracy.

[0025] Such as figure 1 with Figure 4 As shown, the upper end of the frame 1 is located above the discharge nozzle and is provided with a dust suction cover 15, and the lower end of the dust cover on the frame is provided with a cylinder 16 for pressing the bag. The shaft end of the cylinder is provided with a pressing block 161. It is connected with the frame through the cylinder fixing seat 17, the cylinder controller is connected to the cylinder, and the cylinder controller is connected with the control box; a tension spring 18 is arranged between the discharge nozzle 7 and the cylinder fixing seat 17, and the outer end of the discharge nozzle is open Tilt upwards, when the bag is removed, the height of the outer end of the discharge nozzle is higher than the height of the inner end of the discharge nozzle. When the cylinder is pressed down, the height of the outer end of the discharge nozzle is lower than the height of the inner end of the discharge nozzle. The mouth of the material bag is sleeved on the discharge nozzle, and the bag pressing cylinder is lowered to make the connection between the material bag and the discharge nozzle play a positioning role, preventing the upper end of the material bag from being separated from the discharge nozzle during the discharge process of the discharge nozzle and causing material leakage At the same time, under the pressure of the cylinder, the outer end of the discharge nozzle is lower than the inner end, which is convenient for blanking. When the electronic scale detects that the weight of the material bag reaches the set value, the cylinder rises and the motor stops rotating. The outer end of the material nozzle is higher than the inner end under the action of the tension spring, thereby preventing the dry mortar from continuing to fall into the material bag, and the weighing is more accurate.

[0026] With reference to the drawings, the method of use of the present invention is as follows: the material bag is placed on the material bag support frame, the upper opening of the material bag is sleeved on the discharge nozzle, and the control box controls the cylinder to press down so that the material bag and the discharge nozzle are easily positioned, preventing The material bag is disengaged, and the discharge nozzle has no pulling force on the material bag. At the same time, the outer end of the discharge nozzle is lower than the inner end under the action of the pressing block, which is convenient for blanking. At this time, the fan is turned off and the motor is opened under the action of the control box. The dry mortar in the silo enters the feeding channel and is fed into the material bag under the action of the rotating shaft and the spiral belt. The dry mortar is stirred circumferentially and axially at the bottom of the feeding channel to further mix and improve the quality of the dry mortar. The weight of the dry mortar in the material bag increases. When the weight reaches the rated weight, the control box controls the motor and shuts off the fan to notify the rotation, and the cylinder retracts so that the outer end of the discharge nozzle is higher than the inner end, and the dry mortar stops feeding instantly , The weighing accuracy is high, and then the material bag pallet is manually turned over, the elastic telescopic rod retracts, so that the material bag tray rotates 45 degrees and then the material bag is unloaded, then a new material bag is installed, and the control box is opened for the next packaging . Therefore, the invention has the beneficial effects of high discharging efficiency, anti-clogging, and further improving the uniform mixing of dry powder mortar. At the same time, the invention also has the beneficial effects of accurate packing and weighing and convenient unloading.
