Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the heating device of the existing screw extruder is not sensitive during use, which leads to uneven heating, and the heating effect cannot achieve the expected effect, which reduces the quality of the extruded product and requires time-consuming and labor-intensive removal. Repair equipment, or even replace the entire screw

Embodiment 1

[0027] like Figure 1~2 As shown, the present invention provides an extrusion mechanism conducive to uniform heating, which includes a screw extruder main body 1 , a cylindrical screw outer shell 2 and a heating device 3 . The heating device 3 includes two semi-cylindrical casings 4 , one side of the two semi-cylindrical casings 4 is connected by a connecting hinge 5 , and the other side is detachably connected by a compression plate 6 and a compression nut 7 . A flexible electric heating pad 8 is provided on the inner wall of the semi-cylindrical shell 4, and the two semi-cylindrical shells 4 are sleeved on the screw shell 2, and the flexible electric heating pad 8 is pressed and fixed on the inner wall of the semi-cylindrical shell 4 and the screw. Between the outer walls of the outer casing 2. Three heating devices 3 are arranged axially along the screw housing 2 .

Embodiment 2

[0029] Further improvement on the basis of Example 1, one side of the flexible electric heating pad 8 is protruded with four evenly distributed adsorption magnet blocks 9, and the inner wall of the semi-cylindrical shell 4 is concavely provided with the adsorption magnet blocks 9. The adsorption magnet groove 10. The connection between the flexible electric heating pad 8 and the semi-cylindrical housing 4 is realized by embedding and absorbing the magnet block 9 in the groove 10 of the magnet magnet.

[0030] real time 3

[0031] Further improvement on the basis of Example 2, a first temperature sensor is provided on the flexible electric heating pad 8 and the contact surface with the screw housing 2 , and a second temperature sensor is provided on the outer wall of the semi-cylindrical housing 4 . A temperature display 11 is provided outside the semi-cylindrical housing 4 for displaying the temperature readings of the first temperature sensor and the second temperature senso...

Embodiment 4

[0033] As a further improvement on the basis of Embodiment 3, heat-resistant rubber pads 12 are provided on both axial ends of the semi-cylindrical housing 4 along the circumference.

Abstract

The invention discloses an extrusion mechanism beneficial for uniform heating. The extrusion mechanism comprises a screw extruder body, a columnar screw outer shell and heating devices, and each heating device comprises two semi-cylinder-shaped shells, wherein one side edge of one semi-cylinder-shaped shell is connected with one side edge of the other semi-cylinder-shaped shell through a connection hinge, and the other side edge of one semi-cylinder-shaped shell is detachably connected with the other side edge of the other semi-cylinder-shaped shell through compression plates and a compression nut; and the inner wall of each semi-cylinder-shaped shell is provided with a flexible electric heating pad, every two corresponding semi-cylinder-shaped shells sleeve on the columnar screw outer shell, the flexible electric heating pads are fixed between the inner walls of the semi-cylinder-shaped shells and the outer wall of the columnar screw outer shell in a compressed manner, and the heating devices sleeve on the columnar screw outer shell in the axial direction. Assembling, disassembling and maintenance management are convenient to achieve, different heating requirements of the screw section are guaranteed, it is guaranteed that the screw section is evenly heated, and qualified extrusion products are obtained.

Description

technical field [0001] The invention relates to a material processing equipment, in particular to an extruding mechanism which facilitates uniform heating. Background technique [0002] At present, the use of straw in rural agriculture is still an important project. A large amount of crop straw is burned every year, and only a small part is used, such as: as combustion material, feed, etc. The burning straw produces a lot of smoke, causing environmental damage. Serious pollution, in addition to the straw used for combustion, the straw can also be crushed by a pulverizer, mixed with other materials and pressurized by an extruder to process furniture, so as to realize the environmental protection and recycling of straw. The screw extruder relies on the pressure and shear force generated by the rotation of the screw, so that the material can be fully plasticized and evenly mixed, and then formed through the die. The existing screw extruder has a fixed heating structure for the...
