[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] The present invention provides Figure 1-8 The device for solid phase viscosity enhancement of polyester material shown in the figure comprises a processing device body 1, a cover plate 2 is movably installed on the top of the processing device body 1, a containing barrel 3 is rotatably connected inside the processing device body 1, and a rim 4 is fixedly connected to the top edge of the containing barrel 3, and the rim 4 is slidably connected to an annular groove 5 reserved inside the processing device body 1, a cavity 6 is reserved inside the processing device body 1, a motor 7 is fixedly connected to the bottom wall of the processing device body 1, and the output shaft of the motor 7 is transmission-connected to a drive shaft 8, the drive shaft 8 passes through the cavity 6 and is fixedly connected to the bottom wall of the containing barrel 3, and also comprises:

[0037] The rotating assembly 9 has a second cavity 91 reserved at the lower end of the holding barrel 3, and the two sides of the second cavity 91 are connected with notches 92, and the inside of the second cavity 91 is rotatably connected with a large gear 93, and the two sides of the large gear 93 are meshed with small gears 94, and the small gear 94 is meshed with a linkage gear 95;

[0038] The stirring assembly 10, the inner wall of the cavity 2 91 is rotatably connected to the stirring shaft 101, the stirring shaft 101 is fixedly sleeved on the inner ring of the large gear 93, the rotation of the large gear 93 drives the stirring shaft 101 to rotate, and the outer wall of the stirring shaft 101 is fixedly inserted with a stirring blade 102, the outer ring of the stirring shaft 101 is sleeved with a linkage shaft 103 through a linkage part 105, and the outer wall of the linkage shaft 103 is fixedly sleeved with a stirring blade 2 104.

[0039] The inner wall of the cover plate 2 is fixedly connected with an insertion rod 11, and the insertion rod 11 is movably connected to the columnar groove reserved inside the stirring shaft 101, so that the stirring shaft 101 can rotate more stably when the insertion rod 11 is rotationally connected to the stirring shaft 101.

[0040] The edge of the pinion gear 94 protrudes from the outer wall of the containing barrel 3, and the edge of the pinion gear 94 does not contact the inner wall of the processing device body 1, so that it is convenient for the pinion gear 94 to be meshed with the linkage gear 95, and the meshing connection between the pinion gear 94 and the linkage gear 95 does not affect the rotation of the containing barrel 3.

[0041] The linkage gear 95 is rotationally connected to the gear groove 96 reserved inside the processing device body 1 through a rotating rod 97, and the rotating rod 97 extends to the interior of the cavity 6 and is rotationally connected to the inner wall of the cavity 6 through a bearing, and the rotating rod 97 is transmission-connected to the drive shaft 8 through a belt 98.

[0047] The present invention also provides a method for solid phase viscosity enhancement of polyester materials, using the above-mentioned device for solid phase viscosity enhancement of polyester materials, and the specific operating steps are as follows:

[0048] Step 1: Open the cover plate 2 and put the material particles to be processed into the inside of the containing barrel 3, cover the cover plate 2, and ensure that the plug rod 11 fixedly connected to the inner wall of the cover plate 2 matches the columnar groove reserved inside the stirring shaft 101;

[0049] Step 2: Start the motor 7 to drive the barrel 3 fixedly connected to the end wall of the drive shaft 8 to rotate, and the rotating rod 97 connected to the drive shaft 8 through the belt 98 drives the linkage gear 95 to rotate. At this time, the large and small gears are meshed with the linkage gear 95 during the revolution to realize self-rotation. The U-shaped stirring blade 102 and the N-shaped stirring blade 2 104 rotate in different directions under the drive of the linkage 105 to fully stir the materials to be processed in the barrel 3 to prevent the polyester particles from sticking together during the heating process.

[0050] Step 3: Open the cover 2 to take out the material.

[0051] Working principle: When using a device for solid phase viscosity enhancement of polyester material, firstly, the driving shaft 8 connected to the output shaft of the motor 7 is started to rotate, thereby driving the rotation of the containing barrel 3 fixedly connected to the end wall of the driving shaft 8, and the mouth edge 4 fixedly connected to the outer wall of the upper end of the containing barrel 3 rotates inside the annular groove 5 reserved inside the processing device body 1, so as to ensure the stability of the rotation of the containing barrel 3. At the same time, when the driving shaft 8 rotates, the rotating rod 97 connected to the driving shaft 8 through the belt 98 rotates synchronously. During the rotation of the rotating rod 97, the linkage gear 95 is driven to rotate. At the same time, during the rotation of the containing barrel 3, the large gear 93 and the small gear 94 connected in rotation in the internal cavity 91 of the containing barrel 3 are driven to revolve synchronously. In this way, during the revolution of the large gear 93 and the small gear 94, the small gear 94 is intermittently meshed with the linkage gear 95 in the rotating state. At this time, the small gear 94 is intermittently meshed with the rotating linkage gear 95. 94 realizes self-rotation, thereby making the large gear 93 meshing with the small gear 94 rotate synchronously, and the stirring shaft 101 inserted into the inner ring of the large gear 93 realizes synchronous rotation, so that the rotation of the stirring shaft 101 makes the stirring blade 102 rotate to stir the material inside the barrel 3, and at the same time, during the rotation of the stirring shaft 101, the linkage shaft 103 sleeved on the outer ring of the stirring shaft 101 rotates synchronously under the transmission connection of the bevel gear set 1051. Due to the different directions of rotation of the gear meshing connection, the rotation directions of the stirring shaft 101 and the linkage shaft 103 are different. In this way, the rotation directions of the stirring blade 102 and the stirring blade 2 104 fixedly sleeved on the outer ring of the stirring shaft 101 and the linkage shaft 103 are different. The U-shaped stirring blade 102 and the N-shaped stirring blade 2 104 rotate in different directions to fully stir the material to be processed inside the barrel 3, thereby ensuring that the subsequent solid phase viscosity enhancement effect is better.

[0052] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
