DETAILED DESCRIPTION

[0021] In order to better illustrate the content of the utility model, the following is a description with reference to the accompanying drawings and implementation examples:

[0022] have Figure 1As shown, the utility model discloses a mixing extruder for processing refrigerator door seals, including a base 1, an extruder 4 is arranged on the upper side of the base 1, a support portion 2 fixedly arranged on the base 1 is arranged on the upper side of the extruder 4, a support column 3 is fixedly arranged on the upper side of the support portion 2, an extrusion tube 19 is fixedly arranged on the upper side of the support column 3, the middle part of the extrusion tube 19 is connected with an intermediate tube 5 connected with the extruder 4, and stirring mechanisms 900 for melting and mixing raw materials are respectively connected to the upper sides of both ends of the extrusion tube 19.

[0023] Furthermore, the stirring mechanism 900 includes a support rod 16 fixed on the support portion 2, a stirring drum 9 is fixed on the support rod 16, a first heating plate 10 is provided on the inner wall of the stirring drum 9, and the bottom of the stirring drum 9 is connected to the extrusion tube 19 via a connecting tube 8.

[0024] Furthermore, a mounting rod 13 is fixedly disposed on the support rod 16 , and a first motor 12 is fixedly disposed on the mounting rod 13 . The first motor 12 is motively connected to a stirring rod 11 located inside the stirring drum 9 .

[0025] Furthermore, first spiral extrusion shafts 17 are rotatably connected inside both ends of the extrusion tube 19 , and the first spiral extrusion shaft 17 is motively connected to a second motor 7 .

[0026] Furthermore, a mounting plate 14 is fixedly provided between the support rods 16 , a third motor 15 is fixedly provided on the mounting plate 14 , and a second spiral extrusion shaft 6 penetrating through and extending into the intermediate tube 5 is dynamically connected to the lower side of the third motor 15 .

[0027] Furthermore, a one-way transport plate 20 located inside the extrusion tube 19 is also provided at the tail of the first spiral extrusion shaft 17 , and the one-way transport plate 20 is hinged to the inside of the extrusion tube 19 .

[0028] Furthermore, the one-way transport plate 20 can only rotate toward one side of the second screw extrusion shaft 6 .

[0029] Furthermore, a second heating plate 18 is disposed on the inner wall of the extrusion tube 19 .

[0030] Furthermore, a switch valve (not shown) is provided at the upper end of the connecting pipe 8 .

[0031] Specifically, when in use, raw materials are added into the mixing drum 9, the raw materials are melted by the first heating plate 10, and then the first motor 12 is started to drive the mixing rod 11 to rotate, so as to achieve mixing of the raw materials;

[0032] After the mixing is completed, the switch valve is opened, so that the mixed material enters the extrusion tube 19 on the right through the connecting tube 8. At this time, the second motor 7 is started, and then the first spiral extrusion shaft 17 squeezes the raw material to the upper side of the middle tube 5. At this time, the one-way transport plate 20 on the right is pushed away by the raw material and rotates clockwise by a certain angle, so that the raw material enters the middle tube 5.

[0033] However, due to the existence of the one-way transport plate 20 on the left, the raw material cannot enter the extrusion tube 19 on the left, so that the raw material can only move downward and enter the extruder 4 under the drive of the second screw extrusion shaft 6;

[0034] While the raw materials on the right are being extruded, the mixing drum 9 on the left starts to add raw materials and stir them. After all the raw materials on the right have been extruded, the mixing drum 9 on the left has just finished stirring and starts to extrude the raw materials from the extrusion tube 19 at the left end.

[0035] That is, the two mixing drums 9 perform mixing and stirring operations in sequence, and continuously provide mixed raw materials to the extruder 4 .
