Description

Technical Field

[0001] The invention relates to the technical field of hot air penetration, and more particularly to a conversion impact hot air flow module and a hot air penetration paper machine and method. Background Art

[0002] In the process of papermaking, the pulp needs to be dehydrated to facilitate pulp forming. In the existing pulp dehydration device, during the dehydration process, the pulp is squeezed and the net is dehydrated by centrifugal force at high speed, and the white water is discharged into the white water tank. At the same time, there is still some moisture in the pulp, and secondary dehydration is required, resulting in slow work efficiency.

[0003] In order to improve the quality of tissue paper, Procter & Gamble has developed a hot air through-drying technology that can minimize paper web squeezing. This process technology allows the wet paper to be sucked onto a structural fabric that can give the paper a three-dimensional structure, and then the paper web and the structural fabric are transferred together to a large porous roller. At this time, hot dry air with a temperature of up to 350° passes through the structural fabric and the paper web, thereby achieving the purpose of drying the paper web.

[0004] When the paper web is transferred from the porous roller to the Yankee dryer, the paper web has a high dryness. Only 25% of the paper web on the Yankee dryer is compressed, while 100% of the paper web in the traditional dry creping process is compressed. Therefore, the household paper products produced by this new technology have high softness, bulk and absorbency. The processed paper towel can absorb 15 times its own weight in water, while the absorbency of traditional household paper products is only half of the above, making this model a mainstream model in the world.

[0005] With the continuous development of hot air penetration technology, there is a constant pursuit for paper processing with higher softness, bulk and absorbency. In the existing hot air penetration technology, hot air drying is an important core process. The continuous upgrading of the role of hot air in order to improve its processing effect is a problem that technical personnel in this field urgently need to solve. Summary of the invention

[0006] In view of this, the present invention provides a conversion impact hot air flow module and a hot air penetration paper machine and method, aiming to solve the above technical problems.

[0007] In order to achieve the above object, the present invention adopts the following technical solution:

[0008] A variable impingement hot air flow module, comprising:

[0009] An outer shell, one side of which has an opening, an inner wall of which is divided into a plurality of sliding channels by a partition, and the plurality of sliding channels all correspond to the opening;

[0010] A hot air outlet body, wherein the number of the hot air outlet bodies is the same as the number of the sliding channels, and the plurality of hot air outlet bodies are respectively slidably arranged in the sliding channels, the hot air outlet body has a hot air outlet on one side facing the opening, and the other side of the hot air outlet body is connected to a hot air supply pipeline; the distances between the planes where the hot air outlets of the plurality of hot air outlet bodies are located and the plane where the opening is located are not equal;

[0011] A driving mechanism is installed on the outer shell, and a power output end of the driving mechanism is connected to a side of the plurality of hot air outlet bodies away from the hot air outlets thereof, and the driving mechanism can simultaneously drive the plurality of hot air outlet bodies to perform reciprocating linear motion in the sliding channel.

[0012] Through the above technical scheme, the present invention provides a hot air penetration structure that can realize the change of the impact force of hot air blasting. The reciprocating motion of the hot air outlet body in the sliding channel is utilized to realize the alternating movement of multiple hot air outlet bodies, thereby making it possible for the air outlet distance of each hot air outlet body to be changed. At the same time, multiple bodies move together to meet the impact-type hot air fluctuations, thereby changing the traditional single hot air blasting operation and proposing a diversified hot air blasting form. Under the action of the hot air shock wave, the drying effect of the paper tape to be dried is better, which is beneficial to the improvement of softness, bulkiness and absorbency.

[0013] Preferably, in the above-mentioned conversion impingement hot air flow module, the driving mechanism is a crank-connecting rod structure with a motor as the driving force. In order to simplify the structure and improve the feasibility of the structure, the driving mechanism of the present invention adopts a crank-connecting rod structure with a motor as the driving force. It should be noted that the present invention adopts the same crank-connecting rod structure as the four-stroke internal combustion engine in the automotive field. The only difference is that the four-stroke internal combustion engine uses the action of the piston to drive the crank-connecting rod structure to move, and then realizes power output. The present invention operates in reverse, using the motor to provide motion power to the crank-connecting rod structure, thereby driving the hot air outlet body to move.

[0014] Preferably, in the above-mentioned conversion impingement hot air flow module, each of the sliding channels is provided with the crank-connecting rod structure, and the power of the plurality of crank-connecting rod structures is sequentially connected in series, and each crank-connecting rod structure comprises cam 1, cam 2 and a crank; the support shafts of cam 1 and cam 2 are respectively rotatably connected to the two side walls of the sliding channel, one end of the crank is hinged to the hot air outlet body, and the other end of the crank is rotatably connected between cam 1 and cam 2 through a pin shaft. The present invention uses a partition as a support body for the support shaft, replacing the bearing seat, and the bearing can be directly installed on the partition to connect the support shaft.

[0015] Preferably, in the above-mentioned conversion impingement hot air flow module, the motor is fixed on the inner wall of the outer shell, and the power output shaft of the motor passes through the outer shell, and a driving pulley is fixed at the end; the support shafts at one end of the plurality of series-connected crank-connecting rod structures pass through the outer shell, and a driven pulley is fixed at the end, and a transmission belt is sleeved between the driving pulley and the driven pulley. Power is transmitted through the belt, the structure is simple, and the power transmission is stable and reliable.

[0016] Preferably, in the above-mentioned conversion impingement hot air flow module, the crank on each of the hot air outlet bodies is connected to the middle of its top surface, and each of the hot air outlet bodies is connected to two hot air supply pipes, which are symmetrically arranged on both sides of the crank. The connection position of the hot air outlet body, the crank and the hot air supply pipe is reasonable, and can reasonably avoid mutual interference during the action.

[0017] Preferably, in the above-mentioned conversion impingement type hot air flow module, a main interface is installed on a side wall of the outer shell away from the opening, and the main interface is connected to the plurality of hot air supply pipes.

[0018] Preferably, in the above-mentioned conversion impingement hot air flow module, a pressure sensor is installed inside the hot air outlet body. By arranging the pressure sensor inside the hot air outlet body, the hot air pressure can be monitored, which has a stronger intelligent adjustment effect.

[0019] Preferably, in the above-mentioned conversion impingement hot air flow module, the distance between the plane where the hot air outlets of the multiple hot air outlet bodies are located and the plane where the openings are located increases or decreases in sequence. By regularly arranging the positions of the multiple hot air outlets, regularity under irregular movements can be achieved, with more adjustable space.

[0020] The present invention also provides a conversion impact hot air penetrating paper machine, comprising:

[0021] A paper conveying part, the paper conveying part is used to convey the paper tape that needs to be dried, and the conveying surface of the paper conveying part is correspondingly provided with the above-mentioned conversion impact type hot air flow module, and the hot air outlets of the multiple hot air outlet bodies are oriented toward the paper tape that needs to be dried during the conveying process;

[0022] A moisture collecting part is arranged on a side of the paper conveying part facing away from the hot air outlet body, and is used to collect moisture separated during the drying process of the paper tape.

[0023] Through the above technical scheme, the present invention provides a transformable impact type hot air penetration paper machine based on the above hot air impact type structure, and cooperates with the setting of the paper surface conveying part and the moisture collection part to form a complete paper tape drying structure. Since the effect of hot air blowing is different from that of traditional stable hot air, the continuous impact change of hot air can have a stronger effect on the paper tape.

[0024] It should be noted that the principle of the present invention can be referred to blowing air at a paper placed on a desktop with a mouth. By controlling the size of the blowing force to imitate the adjustment of the distance, it can be found that the paper will produce certain fluctuations due to the change in force during the blowing process. This fluctuation can be used to enhance the hot air impact effect on the paper. At the same time, due to the fluctuation of the paper, the paper is not always pressed and penetrated, but has a certain degree of self-floating, which is conducive to improving the flexibility of the paper.

[0025] The present invention also provides a conversion impact hot air penetration method, which adopts the above conversion impact hot air penetration paper machine, specifically comprising:

[0026] By controlling the driving mechanism to switch the movement speed of the hot air outlet body, the intensity of the hot air impact can be changed;

[0027] By setting different numbers of the hot air outlet bodies, or matching different positions with the traditional hot air penetration structure, the performance change of the hot air impact can be achieved.

[0028] Through the above technical scheme, the present invention provides a variable impact hot air penetration method based on the above device structure, which can be adaptively adjusted according to the use requirements, or can be tentatively adjusted to change the movement speed of different hot air outlet bodies, or set different numbers, and arrange different positions, and can also be coordinated with traditional structures to meet different use requirements.

[0029] It can be seen from the above technical solutions that, compared with the prior art, the present invention discloses a conversion impingement hot air flow module and a hot air penetrating paper machine and method, which have the following beneficial effects:

[0030] 1. The present invention provides a hot air penetration structure that can achieve changes in the impact force of hot air blasting. The reciprocating motion of the hot air outlet body in the sliding channel is utilized to achieve the alternate movement of multiple hot air outlet bodies, thereby enabling the air outlet distance of each hot air outlet body to be changed. At the same time, multiple hot air outlet bodies move together to meet the impact-type hot air fluctuations, thereby changing the traditional single hot air blasting operation and proposing a diversified hot air blasting form. Under the action of the hot air shock wave, the drying effect of the paper tape to be dried is better, which is beneficial to the improvement of softness, bulkiness and absorbency.

[0031] 2. Based on the above hot air impact structure, the present invention provides a transformable impact hot air penetration paper machine, which cooperates with the setting of the paper surface conveying part and the moisture collection part to form a complete paper tape drying structure. Since the effect of hot air blowing is different from that of traditional stable hot air, the continuous impact change of hot air can have a stronger effect on the paper tape.

[0032] 3. Based on the above device structure, the present invention provides a method for changing the impact-type hot air penetration, which can be adaptively adjusted according to the use requirements, or can be tentatively adjusted to change the movement speed of different hot air outlet bodies, or set different numbers, and arrange different positions. It can also be coordinated with traditional structures to meet different use requirements. BRIEF DESCRIPTION OF THE DRAWINGS
