Description

Technical Field

[0001] The utility model relates to the technical field of mechanical pulping, in particular to a novel double-screw extrusion impregnation machine. Background Art

[0002] The entire pulping and papermaking process includes but is not limited to: shredders, washers, dehydrators, steaming chambers, squeeze impregnation machines, reaction chambers, latent pulp removal tanks, fiber separators, purification devices, pulp storage devices, etc. The impregnation machine is one of the industrial equipment used in the production of film paper. It can impregnate decorative printing paper, plain paper, surface paper, etc. for subsequent coating and gluing, and finally dry and cut or reel it into sheets for use in artificial board veneer, etc.

[0003] In the existing extrusion impregnation machines, the extrusion screw and the overall equipment are mostly integrated structures, which are driven by a motor. However, the equipment with an integrated structure requires manual addition when adding the impregnation liquid. Manual addition may result in excessive or insufficient addition, which may affect the quality of the product.

[0004] A Chinese patent (authorization announcement date: CN218951839U) proposes a positive and negative pressure double-screw extrusion impregnation machine, in which a transmission gear and two rotating gears located on both sides of the transmission gear and meshing with the transmission gear are installed in the transmission box; a first transmission rod is fixed to the central axis of each rotating gear, and a mounting block is provided at one end of the first transmission rod, and the mounting block has a hollow cavity; two slots are symmetrically opened on the upper and lower sides of the inner surface of the cavity of the mounting block, and a pressure spring and an inner shaft are provided in each slot; one end of the inner shaft extends through the slot to the outside of the mounting block and is fixedly connected to the handle, and the other end of the inner shaft is fixedly connected to the triangular fixing block; the other end of the pressure spring is fixedly connected to the triangular fixing block. In the utility model, when the connector enters the cavity, regardless of whether the clamping strip can directly pop into the clamping slot of the connector, the clamping strip will automatically engage with the clamping slot when the working mounting block of the equipment rotates, and it is easy to disassemble, which facilitates the loading and unloading and replacement of the screw.

[0005] When the above solution is used, it is necessary to add impregnation liquid when making the material, but it is only for quick disassembly and installation, and it is impossible to automatically add impregnation liquid. In order to solve the problem of not being able to automatically add impregnation liquid, we propose a new double-screw extrusion impregnation machine. Utility Model Content

[0035] See also Figure 6 、 Figure 7 、 Figure 8 、 Figure 9, the outer wall of the matching rectangular tube 22 is also fixedly connected to multiple groups of fixed plates 21, and each group of movable arms 23 is fixedly connected to the inside of a second matching tube 26, the inside of the second matching tube 26 is fixedly connected to the first matching tube 25, and the inside of the first matching tube 25 is fixedly connected to a plurality of fixed tubes 29, the fixed tubes 29 are fixedly connected to the second matching tubes 26, and the plurality of fixed tubes 29 are circumferentially released inside the corresponding first matching tube 25, and each group of fixed tubes 29 is fixedly connected to the inside of a second elastic telescopic arm 30, and the output end of the second elastic telescopic arm 30 is fixedly connected to a contact ball 32, and the contact ball 32 is spherical, and the fixed tube 29 An abutment ring is fixedly connected to the bottom end of the inner wall, and the outer wall of the abutment ball 32 abuts against the outer wall of the abutment ring. It is worth noting that when the diameter of the abutment ring is smaller than the diameter of the abutment ball 32, a conical block 24 is provided on the left side of each set of second matching tubes 26, and the conical block 24 is fixedly connected to the upper end of the movable arm 23. The diameter of the conical block 24 is larger than the inner wall diameter of the first matching tube 25, and the conical block 24 is made of rubber. The rubber material has good elasticity and good high temperature resistance and corrosion resistance. The outer wall of the fixed plate 21 is also fixedly connected to a delivery pipe 27, and the delivery pipe 27 is connected to the first matching tube 25.

[0036] See also Figure 2 The outer wall of the storage box 1 is also fixedly connected to the liquid storage tank 6, and the inside of the liquid storage tank 6 is slidably connected to a push plate 7, and the outer wall of the push plate 7 is fixedly connected to a sealing ring, and the outer wall of the sealing ring and the inner wall of the push plate 7 abut against each other. The sealing ring is made of silicone and has good elasticity.

The push plate 7 and the inner wall of the liquid storage tank 6 are fixedly connected by a first elastic telescopic arm 8, and the liquid storage tank 6 and the second matching tube 26 are fixedly connected by a rubber tube. The first elastic telescopic arm 8 will squeeze the impregnation liquid inside the liquid storage tank 6 into the inside of the second matching tube 26 through the push plate 7.

[0037] Working principle: When in use, the drive motor 5 is started, and the drive motor 5 drives the two sets of screw rods 9 to rotate through the first gear 16 and the second gear 19. The screw rods 9 will drive the material inside the storage box 1 to squeeze and move. At this time, the first gear 16 will drive the rotating circular plate 10 to rotate, and the rotating circular plate 10 will drive the moving rod 17 to move back and forth in the inner wall of the moving groove 18. Since the displacement bar 12 will move up and down under the limit of the fixed rod 13, the fixed rod 13 will drive the connecting arm 14 and the bending block 15 to move up and down. When the bending block 15 abuts against the matching wheel 31, the matching wheel 31 will drive the moving arm 23 to move in the inner wall of the matching rectangular tube 22.

[0038] When the movable arm 23 drives the conical block 24 into the first matching tube 25, the outer wall of the conical block 24 will abut against the inner wall of the first matching tube 25. At this time, when the abutting ball 32 abuts against the conical block 24, the abutting ball 32 moves toward the inner wall of the fixed tube 29. At this time, the internal impregnation liquid will enter the first matching tube 25 through the second matching tube 26. The impregnation liquid inside the first matching tube 25 enters the storage box 1 through the conveying tube 27, completing the sowing of the raw materials. Since the displacement bar 12 moves up and down, all the sowing of the impregnation liquid is intermittent, completing the limited sowing, and reciprocating in sequence according to the above working principle.

[0039] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
