It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] Please also read Figure 1 and Figure 2 , the raw material mixing and feeding device for PVC pipes provided by the utility model is now described. The raw material mixing and feeding device for PVC pipes comprises a base 100, a baffle 200, a driving member 300 and a mixing mechanism 400. The base 100 has a accommodating cylinder cavity 110 with an open top. The baffle 200 is slidably connected to the base 100, and the baffle 200 divides the accommodating cylinder cavity 110 into a stirring cavity 111 and a buffer cavity 112 arranged at intervals in the vertical direction. The base 100 is provided with a port 120 for connecting to the air pipe and communicating with the buffer cavity 112. The driving member 300 is arranged on the base 100 and connected to the baffle 200, and is used to drive the baffle 200 to slide, so as to connect the stirring cavity 111 and the buffer cavity 112, or to separate the stirring cavity 111 and the buffer cavity 112. The mixing mechanism 400 is arranged on the base 100, and has a stirring portion extending into the stirring cavity 111.

[0028] The base 100 is provided with a sliding cavity for the baffle 200 to slide and communicated with the accommodating cylinder cavity 110 .

[0029] The working principle of the raw material mixing and feeding device for PVC pipes provided in this embodiment is as follows: by pouring raw materials and masterbatches into the containing barrel cavity 110, the raw materials and masterbatches in the stirring chamber 111 are evenly mixed by the stirring part of the mixing mechanism 400. When it is necessary to mix the raw materials, the stirring chamber 111 and the buffer chamber 112 are first connected by the baffle 200, the materials in the stirring chamber 111 are transported to the buffer chamber 112, and then the stirring chamber 111 and the buffer chamber 112 are separated by the baffle 200 to mix the newly entered raw materials and masterbatches.

[0030] Compared with the prior art, the raw material mixing and feeding device for PVC pipes provided in this embodiment is provided with a base 100, and the accommodating cylinder cavity 110 with an open top on the base 100 can carry raw materials. A baffle 200 is slidably provided on the base 100, which can separate the accommodating cylinder cavity 110 into a stirring chamber 111 and a buffer chamber 112 arranged at intervals in the vertical direction, the stirring chamber 111 can be used for mixing raw materials, and the buffer chamber 112 can be used for storing raw materials. A driving member 300 is provided on the base 100, which can be connected to the baffle 200 and drive the baffle 200 to slide, connect or separate the stirring chamber 111 and the buffer chamber 112. A mixing mechanism 400 is provided on the base 100, which can extend into the stirring chamber 111 to stir the materials in the stirring chamber 111. The problem of large lateral space occupation is solved, and the adaptability and practicality are good.

[0031] In some embodiments, the mixing mechanism 400 may be used as follows: Figure 1 See the structure shown. Figure 1 The mixing mechanism 400 includes: a suspension arm 410, a rotating shaft 420, a stirring structure 430 and a driver 440. The suspension arm 410 is disposed on the base 100 and has a mounting end located above the accommodating cylinder chamber 110. The rotating shaft 420 is rotatably disposed on the mounting end along the vertical direction, and the bottom end of the rotating shaft 420 extends into the stirring chamber 111. A plurality of stirring structures 430 are provided, and the plurality of stirring structures 430 are spaced apart along the vertical direction on the rotating shaft 420 for stirring the materials in the stirring chamber 111. The driver 440 is used for driving the rotating shaft 420 to rotate.

[0032] In some embodiments, the driver 440 may be implemented as follows: Figure 1 See the structure shown. Figure 1 , the driver 440 is a servo motor.

[0033] The boom 410 can fix the rotating shaft 420 and the driver 440. The boom 410 can be understood as a cantilever that is arranged on a column on the base 100 and extends above the accommodating cylinder cavity 110. It can also be a gantry. The rotating shaft 420 can rotate along the vertical direction and is arranged on the mounting end to drive the stirring structure 430 to stir the material in the stirring cavity 111. The driver 440 can be a servo motor or a torque motor.

[0034] The baffle 200 can be understood as an insert plate slidably set on the side wall of the base 100. When the insert plate slides outward under the drive of the driving member 300, a through opening is formed between the stirring chamber 111 and the buffer chamber 112. The through opening can be understood as a feed port arranged at the bottom of the stirring chamber 111 and connected to the buffer chamber 112. The shape of the feed port is a long strip hole with a length equal to the radius of the accommodating barrel chamber 110.

[0035] The stirring structure 430 located at the bottom among the multiple stirring structures 430 is in contact with the baffle 200. When the baffle 200 opens to connect the stirring chamber 111 and the buffer chamber 112, the material in the stirring chamber 111 can be pushed into the long hole through the stirring structure 430, thereby ensuring that no material from the previous batch remains in the stirring chamber 111, and the color of the next batch of pipes can be changed by changing the color of the masterbatch.

[0036] In some embodiments, the driver 440 may be implemented as follows: Figure 1 See the structure shown. Figure 1 , the driver 440 is a servo motor.

[0037] The servo motor can control the speed and position with high accuracy, and can convert the voltage signal into torque and speed to drive the control object. The servo motor is a prior art and will not be described in detail here.

[0038] In some embodiments, the stirring structure 430 may be configured as follows: Figure 1 , Figure 2 See the structure shown. Figure 1 , Figure 2 Each stirring structure 430 includes a plurality of stirring arms 431 , which are arranged on the rotating shaft 420 at annular intervals along the axial direction of the rotating shaft 420 , and one end of each stirring arm 431 is fixed on the rotating shaft 420 , and the other end extends outward along the radial direction of the rotating shaft 420 .

[0039] Wherein, every two adjacent stirring structures 430 are staggered.

[0040] The stirring structure 430 disposed at the bottom abuts against the baffle 200 , and the stirring arm 431 of the stirring structure 430 can be understood as a scraper, which can push the material at the bottom of the stirring chamber 111 into the buffer chamber 112 to ensure uniform mixing of the next batch of materials.

[0041] In some embodiments, the driving member 300 may be configured as follows: Figure 1 See the structure shown. Figure 1 , the driving member 300 is a cylinder.

[0042] The cylinder refers to a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder. The air in the engine cylinder converts heat energy into mechanical energy by expansion. The cylinder is a prior art and will not be described in detail here.

[0043] In some embodiments, the base 100 may be formed as follows: Figure 1 See the structure shown. Figure 1 The base 100 also has a guide tube 130, which is funnel-shaped. The small opening of the guide tube 130 is arranged at the open opening of the accommodating tube cavity 110, and the large opening of the guide tube 130 is arranged above the small opening of the guide tube 130 in the vertical direction.

[0044] The guide cylinder 130 can prevent the material from splashing out of the containing cylinder cavity 110 during the stirring process.

[0045] It is only a preferred embodiment of the present invention and is not intended to limit the present invention.
