Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1 - 4 , an embodiment of the present invention provides a stable feeding device for PVC pipe dry mix, including: a hopper 3, a PVC pipe forming raw material mixing mechanism 2, and a feeding mechanism 4. The hopper 3, the PVC pipe forming raw material mixing mechanism 2, and the feeding mechanism 4 are respectively arranged on the top of the base 1. The feeding mechanism 4 is communicated with the bottom of the hopper 3, and some components of the PVC pipe forming raw material mixing mechanism 2 rotate inside the hopper 3;

[0026] Among them, the hopper 3 is fixedly connected to the top of the base 1. The top of the hopper 3 is symmetrically installed with cover plates 301 through bolts 302, and a filling port 303 is opened on one of the cover plates 301.

[0027] Among them, the PVC pipe forming raw material mixing mechanism 2 includes a column 201. The column 201 is fixedly connected to the top of the base 1. A screw rod 202 is rotatably connected to the middle of the column 201. A support block 203 is screwed on the surface of the screw rod 202. The support block 203 is slidably connected inside the column 201. One end of the support block 203 is provided with a motor 204. The end of the output shaft of the motor 204 is fixedly connected with a stirring rod 205. The end of the stirring rod 205 extends into the hopper 3. A slot 207 is opened at the end of the stirring rod 205, and a cutting blade 206 is inserted into the slot 207. By setting the PVC pipe forming raw material mixing mechanism 2 and arranging the screw rod 202 in the middle of the column 201, the screw rod 202 rotates to drive the support block 203 to move up and down, thereby driving the motor 204 at the end of the support block 203 to move up and down, so that the stirring rod 205 connected to the end of the motor 204 moves up and down in the hopper 3, so that the cutting blade 206 at the end of the stirring rod 205 mixes and stirs the PVC pipe dry mix in the hopper 3. By driving the cutting blade 206 by the motor 204, dry mixes with different densities and particle sizes are fully mixed in the hopper, effectively preventing the occurrence of material stratification.

[0028] Among them, jacks 210 are provided at the ends of the stirring rod 205 and the cutting blade 206. A pin 208 is inserted into the jacks of the stirring rod 205 and the cutting blade 206. A spring 209 is sleeved on the surface of the pin 208, and both ends of the spring 209 are fixedly connected to the stirring rod 205 and the head of the pin 208 respectively. By inserting the pin 208 on the surface of the stirring rod 205, the elastic work of the spring 209 can stably fix the cutting blade 206 on the stirring rod 205. And when the cutting blade 206 is worn and needs to be replaced, the pin 208 is pulled out so that the end of the pin 208 is separated from the cutting blade 206, and then the cutting blade 206 can be replaced, which greatly facilitates the operation of the staff and saves time and effort.

[0029] Among them, one end of the screw rod 202 penetrates through the column 201 and is provided with a first gear 211. The first gear 211 meshes with a second gear 212, and the second gear 212 is installed on the output shaft of the stepping motor 213. The stepping motor 213 is fixed on one side of the column 201. By setting the stepping motor 213 and starting the stepping motor 213, the power of the stepping motor 213 is transmitted to the first gear 211 through the second gear 212, thereby driving the screw rod 202 to rotate, and the support block 203 screwed on the screw rod 202 moves up and down, so as to control the depth of the cutting blade 206 in the hopper 3.

[0030] Among them, the blanking mechanism 4 includes a discharging screw 402. The discharging screw 402 rotates in the groove 102 at the top of the base 1. The groove 102 is communicated with the bottom of the hopper 3. One end of the discharging screw 402 penetrates through the base 1 and is fixedly connected to the end of the output shaft of the second motor 401. The second motor 401 is fixedly installed on the base 1. By setting the blanking mechanism 4, the second motor 401 drives the discharging screw 402 to rotate in the groove 102, and the mixed materials can flow out evenly and stably.

[0031] Among them, a discharge port 101 is provided at one end of the base 1. The discharge port 101 is communicated with the groove 102. An insertion plate 403 is inserted into the discharge port 101, and the insertion plate 403 is inserted between the groove 102 and the hopper 3. By setting the discharge port 101, the mixed dry blend of PVC pipes can be discharged smoothly. And by inserting the insertion plate 403 on the discharge port 101, and the insertion plate 403 is inserted between the groove 102 and the hopper 3, it can play an isolation role between the groove 102 and the hopper 3 to prevent the unmixed materials from leaking out.

[0032] The working principle of the present utility model is as follows: During use, the base 1 is stably placed on the platform, and the PVC pipe dry mixture is put into the feeding hopper 3 from the filling port 303. The first motor 204 is started to drive the stirring rod 205 to rotate, thereby driving the cutting blade 206 at the end of the stirring rod 205 to rotate, so as to perform a mixing operation on the PVC pipe dry mixture in the hopper 3. The stepping motor 213 is started, and the second gear 212 on the output shaft of the stepping motor 213 drives the first gear 211 to rotate, thereby driving the screw rod 202 to rotate, causing the support block 203 to move up and down, so that the cutting blade 206 at the end of the output shaft of the first motor 204 moves up and down in the hopper 3. By driving the cutting blade 206 to rotate by the first motor 204, the dry mixtures with different densities and particle sizes are fully mixed in the hopper, effectively preventing the occurrence of material stratification. After the stirring is completed, the insertion plate 403 is pulled open, and the second motor 401 is used to drive the discharge screw rod 402 to rotate in the trough body 102, so that the mixed material can flow out evenly and stably, that is, the operation of the stable feeding device for the PVC pipe dry mixture is completed.
