Description

Technical Field

[0001] The utility model relates to the field of high-sizing and fast-curing AKD emulsions, and particularly relates to a feeding mechanism for high-sizing and fast-curing AKD emulsions. Background Art

[0002] The feeding mechanism of high-sizing and fast-curing AKD emulsions is usually a device that can evenly and accurately apply AKD emulsions to the paper surface. The specific design of this mechanism may vary depending on the production equipment and processes. Generally speaking, it may include the following parts: a storage container for storing AKD emulsions, usually a sealed tank or container to prevent the emulsions from being contaminated or volatilized; a feeding device, which is the core part of the feeding mechanism, and evenly applies the emulsions to the paper surface.

[0003] However, other substances are usually added to high-sizing and fast-curing AKD emulsions, such as cationic starch, wax powder, etc. These additives may affect the fluidity of the emulsions and make them thick. The addition of cationic starch may, due to its own properties and interactions with AKD emulsions, change the overall structure and performance of the emulsions to a certain extent, thereby affecting the fluidity of the emulsions and causing them to tend to become thick; for additives such as wax powder, their own physical and chemical properties may also interact with the emulsions, may interfere with the dispersion state and movement laws of the particles in the emulsions, and thus cause viscosity changes in the emulsions, resulting in the situation of becoming thick. The presence of these additives and their complex interaction mechanisms with AKD emulsions may all be important factors leading to changes in the fluidity of the emulsions and becoming thick. The thickened high-sizing and fast-curing AKD emulsions are more troublesome to feed and flow relatively slowly.

[0004] Therefore, we propose a feeding mechanism for high-sizing and fast-curing AKD emulsions. Content of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a feeding mechanism for high-sizing and fast-curing AKD emulsions, and solve the problem that the thickened high-sizing and fast-curing AKD emulsions are difficult to feed through an extrusion feeding method.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions:

[0007] A feeding mechanism for high-sizing and fast-curing AKD emulsions includes a bottom plate. A telescopic rod is fixedly connected to the middle of the bottom plate. The upper end of the telescopic rod is fixedly connected to a connecting rod. A feeding assembly is arranged at the lower end of the connecting rod. A pair of symmetrically arranged liquid storage tanks are also fixedly connected to the middle of the bottom plate. Connecting pipes are communicated with the upper ends of the pair of liquid storage tanks;

[0008] In this solution, the manufactured paper is placed at the upper end of the bottom plate. The telescopic rod drives the connecting rod to drive the blanking component to lift and lower. After descending and approaching the upper end of the bottom plate, the mixed high-sizing fast-curing AKD emulsion is provided to the blanking component through the liquid storage tank and the connecting pipe, and blanking is carried out through the blanking component.

[0009] Furthermore, the blanking component includes a connecting block fixedly connected to the lower end of the connecting rod. The lower end of the connecting block is fixedly connected with an electromagnetic housing. The lower end of the electromagnetic housing is fixedly connected with a blanking housing, and the inside of the blanking housing is communicated with the inside of a pair of connecting pipes.

[0010] Furthermore, a plurality of blanking hoppers are fixedly connected to the middle of the blanking housing. Rubber blocks are slidably connected inside the plurality of blanking hoppers. The upper end of the rubber block is fixedly connected with a moving rod, and the upper end of the moving rod is fixedly connected with a magnetic block.

[0011] Furthermore, a plurality of electromagnets are fixedly connected inside the electromagnetic housing. The plurality of electromagnets and the plurality of magnetic blocks are arranged in one-to-one correspondence, and the electromagnets and the magnetic blocks are arranged with the same poles facing each other;

[0012] In this solution, a pair of liquid storage tanks provide the high-sizing fast-curing AKD emulsion to the inside of the blanking housing. The high-sizing fast-curing AKD emulsion inside enters the inside of the plurality of blanking hoppers respectively through a plurality of holes opened in the middle of the blanking hoppers. By controlling the plurality of electromagnets to cut off the power supply, the plurality of electromagnets repel the plurality of magnetic blocks. The magnetic blocks are repelled and move away from the electromagnets. The movement of the magnetic blocks drives the moving rods fixedly connected to the middle thereof to move. The movement of the moving rods drives the rubber blocks fixedly connected to the lower ends thereof to move, thereby squeezing the high-sizing fast-curing AKD emulsion inside the blanking hoppers to make it release outward. Discharging is carried out through a plurality of separation control squeezing methods. The blanking of a single blanking hopper 605 can be carried out separately. At the same time, in cooperation with the control squeezing method of the electromagnet 604 and the magnetic block 608, it is possible to more easily control the discharging of a single blanking hopper 605. In this way, blanking can be carried out for a local area of the paper, or it can be adjusted according to the size of the paper.

[0013] Furthermore, the lower end of the blanking hopper is arranged in a conical shape.

[0014] Furthermore, a plurality of feed holes are opened in the middle of the blanking hopper. The inside of the blanking hopper is communicated with the inside of the blanking housing through the feed holes;

[0015] In this solution, due to the lower end of the blanking hopper being arranged in a conical shape, the conical opening can make the material converge and extrude more concentratedly, which is beneficial to improving the directivity and accuracy of discharging.

[0016] Furthermore, a through hole is formed at the lower end of the material discharging outer shell for the through of the discharging hopper;

[0017] In this solution, a through hole is formed at the lower end of the material discharging outer shell for the through of the discharging hopper, which plays a role in facilitating installation.

[0018] In summary, the utility model has the following beneficial effects:

[0019] 1. Through the mutual cooperation between the parts of the material discharging assembly, the high sizing fast curing AKD emulsion can be extruded and discharged by extrusion, preventing the problem of difficult discharging due to the thick and slow flowing of the high sizing fast curing AKD emulsion;

[0020] 2. Through the setting of separated extrusion of multiple discharging hoppers, a single discharging hopper can be extruded and discharged alone. At the same time, by cooperating with the electromagnet and the magnetic block to control the extrusion method, it is possible to more easily control the discharging of a single discharging hopper, so that the material can be discharged locally for the paper or adjusted according to the size of the paper.

A telescopic rod 2 is fixedly connected to the middle of the bottom plate 1. The upper end of the telescopic rod 2 is fixedly connected to a connecting rod 3. A feeding component 6 is arranged at the lower end of the connecting rod 3. A pair of symmetrically arranged liquid storage tanks 4 are also fixedly connected to the middle of the bottom plate 1. Connecting pipes 5 are communicated with the upper ends of the pair of liquid storage tanks 4;

[0030] In this solution, the produced paper is placed on the upper end of the bottom plate 1. The telescopic rod 2 is driven to drive the connecting rod 3 to drive the feeding component 6 to lift and lower. After descending and approaching the upper end of the bottom plate 1, the mixed high-sizing and fast-curing AKD emulsion is provided for the feeding component 6 through the liquid storage tank 4 and the connecting pipe 5, and the feeding is carried out through the feeding component 6.

[0031] Referring to Figures 2 to 5 As shown, the feeding component 6 includes a connecting block 603 fixedly connected to the lower end of the connecting rod 3. An electromagnetic housing 601 is fixedly connected to the lower end of the connecting block 603. A discharging housing 602 is fixedly connected to the lower end of the electromagnetic housing 601, and the inside of the discharging housing 602 is communicated with the inside of the pair of connecting pipes 5;

[0032] A plurality of discharging hoppers 605 are fixedly connected to the middle of the discharging housing 602. Rubber blocks 606 are slidably connected inside the plurality of discharging hoppers 605. A moving rod 607 is fixedly connected to the upper end of the rubber block 606. A magnetic block 608 is fixedly connected to the upper end of the moving rod 607;

[0033] A plurality of electromagnets 604 are fixedly connected to the inside of the electromagnetic housing 601. The plurality of electromagnets 604 and the plurality of magnetic blocks 608 are arranged in one-to-one correspondence, and the electromagnets 604 and the magnetic blocks 608 are arranged with the same poles facing each other;

[0034] In this solution, a pair of liquid storage tanks 4 provides a high-sizing and fast-curing AKD emulsion for the interior of the discharging housing 602. The high-sizing and fast-curing AKD emulsion inside enters the interiors of multiple discharging hoppers 605 respectively through a plurality of holes opened in the middle of the discharging hopper 605. By controlling the energization and disconnection of multiple electromagnets 604, the multiple electromagnets 604 repel multiple magnetic blocks 608. The magnetic blocks 608 are repelled and move away from the electromagnets 604. The movement of the magnetic blocks 608 drives the moving rod 607 fixedly connected to the middle thereof to move. The movement of the moving rod 607 drives the rubber block 606 fixedly connected to the lower end thereof to move, thereby squeezing the high-sizing and fast-curing AKD emulsion inside the discharging hopper 605 to make it release outward. The discharging is carried out by means of multiple separation-controlled squeezes. It is possible to squeeze and discharge a single discharging hopper 605 alone. At the same time, in cooperation with the control squeeze method of the electromagnet 604 and the magnetic block 608, it is possible to more easily control the discharging of a single discharging hopper 605. In this way, it is possible to carry out discharging for a local part of the paper, or to adjust according to the size of the paper.

[0036] A plurality of feed holes are opened in the middle of the discharging hopper 605, and the interior of the discharging hopper 605 is communicated with the interior of the discharging housing 602 through the feed holes;

[0037] In this solution, due to the tapered setting of the lower end of the discharging hopper 605, the tapered opening can make the material converge and extrude more concentratedly, which is beneficial to improving the directivity and accuracy of discharging.

[0038] Refer to Figure 4 As shown, a through hole for the discharging hopper 605 to pass through is opened at the lower end of the discharging housing 602;

[0039] In this solution, by opening a through hole at the lower end of the discharging housing 602 for the discharging hopper 605 to pass through, it plays a role of facilitating installation.

Control the multiple electromagnets 604 to cut off the power supply, so that the multiple electromagnets 604 repel the multiple magnetic blocks 608. The magnetic blocks 608 are repelled and move away from the electromagnets 604. The movement of the magnetic blocks 608 drives the moving rod 607 fixedly connected to the middle thereof to move. The movement of the moving rod 607 drives the rubber block 606 fixedly connected to the lower end thereof to move, thereby squeezing the high-sizing fast-curing AKD emulsion inside the blanking hopper 605 to release it outward. Carry out discharging through multiple separation control squeezing methods. The blanking of a single blanking hopper 605 can be carried out separately. At the same time, in cooperation with the control squeezing method of the electromagnet 604 and the magnetic block 608, it is possible to more easily control the discharging of a single blanking hopper 605. In this way, blanking can be carried out for the local part of the paper, or it can be adjusted according to the size of the paper. The lower end of the blanking hopper 605 is provided in a conical shape, and the conical opening can make the material converge and extrude more concentratedly, which is beneficial to improving the directionality and accuracy of discharging.
