Description

Technical Field

[0001] This invention relates to the field of shoe material production equipment technology, specifically to a polymer material foaming tank for shoe material production and its working method. Background Technology

[0002] Polymer materials are materials with macromolecular structures formed by polymerization reactions based on high molecular compounds. They have the characteristics of being lightweight, highly plastic, and having adjustable properties. They are widely used in industrial and daily life fields. In the production of shoe materials, polymer material products need to be pre-foamed in a foaming tank before molding.

[0003] In existing polymer foaming tanks, after the material is put into the foaming tank, the stirring shaft of the foaming tank is started to stir the material and mix the different materials. However, when the material is stirred in the existing foaming tank, the stirring blades can only stir in a circumferential direction, which makes the material prone to stratification during the stirring process, resulting in low material mixing efficiency. At the same time, some material will settle at the bottom of the tank and cannot participate in the stirring and mixing, resulting in poor mixing effect. Summary of the Invention

[0004] The purpose of this invention is to provide a polymer foaming tank for shoe material production and its working method, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A polymer foaming tank for shoe material production and its working method, comprising:

[0007] The tank body has a fixed shaft inside, and the surface of the fixed shaft has a waist groove, and the inside of the waist groove has an arc-shaped groove.

[0008] A rotating sleeve is fitted onto the surface of the fixed shaft. A stirring blade is fixedly provided on the surface of the rotating sleeve. A reinforcing tube is provided in the middle of the stirring blade. A turbulence-inducing blade is rotatably provided on the surface of the stirring blade.

[0009] The telescopic rod is slidably inserted into the interior of the reinforcing tube.

[0010] Preferably, a lid is provided on the top of the tank body, the lid is detachably connected to the tank body, and a drive motor is fixedly installed on the surface of the lid.

[0011] Preferably, the fixed shaft is fixedly connected to the bottom of the tank, and the fixed shaft is located in the middle of the tank.

[0012] Preferably, the waist groove has an annular groove structure, and multiple sets of waist grooves are formed along the axial direction of the fixed shaft. Multiple sets of arc-shaped grooves are formed inside each set of waist grooves, and the multiple sets of arc-shaped grooves inside each set of waist grooves are distributed in a circumferential array.

[0013] Preferably, the rotating sleeve is fixedly connected to the output shaft of the drive motor, and the rotating sleeve is rotatably connected to the fixed shaft.

[0014] Preferably, the stirring blades are inclined, and there are multiple sets of stirring blades arranged in a spiral shape, with the bottom of the lowest set of stirring blades slidingly attached to the bottom of the tank.

[0015] Preferably, the reinforcing tube and the stirring blade are integral structures, the reinforcing tube has an internal expansion groove, and multiple sets of rotating sleeves are fixedly installed on the surface of the reinforcing tube, with the rotating sleeves communicating with the interior of the expansion groove.

[0016] Preferably, a rotating shaft is fixedly connected to the bottom of the deflector blade, the rotating shaft is rotatably inserted into the interior of the rotating sleeve, a linkage rod is fixedly connected to the bottom of the rotating shaft, and a sliding groove is formed on the surface of the linkage rod.

[0017] Preferably, the surface of the telescopic rod is provided with a first clearance groove and a second clearance groove, the first clearance groove and the second clearance groove are connected, a fixed column is fixedly installed inside the second clearance groove, the fixed column is slidably disposed inside the sliding groove, the fixed column drives the linkage rod to swing through the sliding groove, a reciprocating roller is installed at the end of the telescopic rod near the fixed shaft, the reciprocating roller is slidably disposed inside the arc-shaped groove, and a compression spring is provided at the end of the telescopic rod away from the fixed shaft;

[0018] One end of the rotating sleeve is located inside the first clearance groove.

[0019] A working method for a polymer foaming tank used in shoe material production is as follows:

[0020] Step 1: Put the polymer material to be foamed into the inside of the tank, and then fix the tank cover on top of the tank so that the output shaft of the drive motor is connected to the rotating sleeve.

[0021] Step 2: Start the drive motor. The drive motor drives the rotating column sleeve to rotate, and the rotating column sleeve drives multiple sets of stirring blades to rotate simultaneously, stirring the material inside the tank and mixing the material. The set of stirring blades at the bottom pushes the material at the bottom of the tank up during the rotation. Then, the multiple sets of stirring blades arranged in a spiral shape push the material upwards in one go, and then the material falls down under the action of gravity.

[0022] Step 3: As the rotating column sleeve drives the stirring blade to rotate, the reciprocating rollers move in multiple sets of arc grooves inside the waist groove, causing the telescopic rod to reciprocate inside the reinforcing tube.

[0023] Step 4: The fixed column drives the linkage rod to swing, and the linkage rod drives the turbulence blade to swing through the rotating shaft, thus disturbing the material flow pushed up by the stirring blade.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. By setting multiple sets of spirally arranged stirring blades, the materials inside the tank are stirred and mixed. The bottom set of stirring blades pushes the materials at the bottom of the tank up during rotation. Then, the multiple sets of spirally arranged stirring blades push the materials upward in one go. Under the action of gravity, the materials fall down, thus avoiding the formation of stratification during the stirring process and preventing the materials from settling at the bottom of the tank. This improves the mixing efficiency and foaming effect of the materials.

[0026] 2. By setting up turbulence blades, the rotating column sleeve drives the stirring blades to rotate, and the reciprocating rollers move in multiple sets of arc grooves inside the waist groove, causing the telescopic rod to reciprocate inside the reinforcing tube, driving the linkage rod to swing. The linkage rod drives the turbulence blades to swing through the rotating shaft, disturbing the material flow pushed up by the stirring blades, thereby forming a complex material flow inside the tank, further improving its mixing degree and foaming efficiency.

[0042] Please see the appendix Figure 1 To be continued Figure 9 As shown, the present invention provides a polymer foaming tank for shoe material production and its working method, comprising:

[0043] The tank body 1 has a lid 11 on its top, which is detachably connected to the tank body 1. A drive motor 2 is fixedly mounted on the surface of the lid 11. A fixed shaft 4 is provided inside the tank body 1 and is fixedly connected to the bottom of the tank body 1. The fixed shaft 4 is located in the middle of the tank body 1. A waist groove 41 is formed on the surface of the fixed shaft 4. The waist groove 41 has an annular groove structure. Multiple sets of waist grooves 41 are formed along the axial direction of the fixed shaft 4. Arc grooves 42 are formed inside the waist grooves 41. Multiple sets of arc grooves 42 are formed inside each set of waist grooves 41, and the multiple sets of arc grooves 42 inside each set of waist grooves 41 are arranged in a circumferential array.

[0044] A rotating sleeve 3 is fitted onto the surface of the fixed shaft 4. The rotating sleeve 3 is fixedly connected to the output shaft of the drive motor 2 and rotatably connected to the fixed shaft 4. A stirring blade 5 is fixedly mounted on the surface of the rotating sleeve 3. The stirring blade 5 is inclined and consists of multiple sets arranged in a spiral pattern. The bottom of the lowest set of stirring blades 5 slides against the bottom of the tank body 1. A reinforcing tube 51 is provided in the middle of each stirring blade 5. The tube 51 and the stirring blade 5 are integral structures. The inside of the reinforcing tube 51 is provided with a telescopic groove 53. Multiple sets of rotating sleeves 52 are fixedly installed on the surface of the reinforcing tube 51. The rotating sleeves 52 are connected to the inside of the telescopic groove 53. The surface of the stirring blade 5 is rotatably provided with a baffle 6. The bottom of the baffle 6 is fixedly connected with a rotating shaft 61. The rotating shaft 61 is rotatably inserted into the inside of the rotating sleeve 52. The bottom of the rotating shaft 61 is fixedly connected with a linkage rod 62. The surface of the linkage rod 62 is provided with a sliding groove 63.

[0045] The telescopic rod 7 is slidably inserted into the interior of the reinforcing tube 51. The surface of the telescopic rod 7 has a first clearance groove 71 and a second clearance groove 72, which are connected. A reciprocating roller 74 is installed at one end of the telescopic rod 7 near the fixed shaft 4. The reciprocating roller 74 is rolled inside the arc-shaped groove 42.

The fixed post 73 drives the linkage rod 62 to swing through the sliding groove 63.

[0046] A working method for a polymer foaming tank used in shoe material production is as follows:

[0047] Step 1: Put the polymer material to be foamed into the inside of the tank 1, and then fix the tank cover 11 on top of the tank 1 so that the output shaft of the drive motor 2 is connected to the rotating sleeve 3.

[0048] Step 2: Start the drive motor 2. The drive motor 2 drives the rotating column sleeve 3 to rotate. The rotating column sleeve 3 drives multiple sets of stirring blades 5 to rotate simultaneously, stirring the material inside the tank 1 and mixing the material. The set of stirring blades 5 at the bottom pushes the material at the bottom of the tank 1 up during the rotation. Then, the multiple sets of stirring blades 5 arranged in a spiral shape push the material upwards in one go. Then, the material falls down under the action of gravity.

[0049] Step 3: As the rotating column sleeve 3 drives the stirring blade 5 to rotate, the reciprocating roller 74 moves in the multiple sets of arc grooves 42 inside the waist groove 41, causing the telescopic rod 7 to reciprocate inside the reinforcing tube 51.

[0050] Step 4: The fixed column 73 drives the linkage rod 62 to swing, and the linkage rod 62 drives the turbulence vane 6 to swing through the rotating shaft 61, thereby disturbing the material flow pushed up by the stirring blade 5.

[0051] This invention proposes a foaming tank for polymer materials used in shoe material production. In use, the polymer material to be foamed is placed inside the tank body 1, and then the tank lid 11 is fixed above the tank body 1. The output shaft of the drive motor 2 is connected to the rotating sleeve 3. The drive motor 2 is started, causing the rotating sleeve 3 to rotate. The rotating sleeve 3 drives multiple sets of stirring blades 5 to rotate simultaneously, stirring the material inside the tank body 1 and mixing it. The bottom set of stirring blades 5 pushes the material at the bottom of the tank body 1 up during rotation, and then the multiple sets of stirring blades 5 arranged in a spiral shape push the material upwards in one go. Under the action of gravity, the material falls down, thus avoiding stratification during stirring and preventing material deposition at the bottom of the tank body 1, improving the mixing efficiency and foaming effect.

[0052] As a further improvement of the present invention, by setting up the turbulence vane 6, the rotating column sleeve 3 drives the stirring blade 5 to rotate, and the reciprocating roller 74 moves in multiple sets of arc grooves 42 inside the waist groove 41, so that the telescopic rod 7 reciprocates inside the reinforcing tube 51, driving the linkage rod 62 to swing. The linkage rod 62 drives the turbulence vane 6 to swing through the rotating shaft 61, disturbing the material flow pushed up by the stirring blade 5, thereby forming a complex material flow inside the tank 1, further improving its mixing degree and foaming efficiency.

[0053] Working Principle: This invention proposes a foaming tank for polymer materials used in shoe material production. In use, the polymer material to be foamed is placed inside the tank body 1, and the tank cover 11 is fixed above the tank body 1. The output shaft of the drive motor 2 is connected to the rotating sleeve 3. The drive motor 2 is started, causing the rotating sleeve 3 to rotate. The rotating sleeve 3 drives multiple sets of stirring blades 5 to rotate simultaneously, stirring the material inside the tank body 1 and mixing it. The bottom set of stirring blades 5 pushes the material at the bottom of the tank body 1 up during rotation. Then, the multiple sets of stirring blades 5 arranged in a spiral shape push the material upwards in one go. Under the action of gravity, the material falls. As the rotating sleeve 3 drives the stirring blades 5 to rotate, the reciprocating roller 74 moves in multiple arc-shaped grooves 42 inside the waist groove 41, causing the telescopic rod 7 to reciprocate inside the reinforcing tube 51, driving the linkage rod 62 to swing. The linkage rod 62 drives the turbulence blade 6 to swing through the rotating shaft 61, disturbing the material flow pushed up by the stirring blades 5.
