[0036] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can also be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0037] Example:

[0038] At present, there is no equipment on the market that can be used for the disinfection of large quantities of paper, and traditional disinfection measures cannot be applied to paper disinfection. Therefore, we propose a device that can be used for the rapid disinfection of large quantities of paper. The specific plan is as follows:

[0039] like Figure 1 As shown, the present example discloses an automatic paper feeding ultraviolet paper sterilizer, which specifically includes a lower chassis 1 and an upper chassis 2. Paper inlet and outlet are respectively provided at the bottom of both sides of the upper chassis 2. A paper loading device 4 is installed at the paper inlet position of the bottom of the upper chassis 2, and a paper receiving tray 3 is provided at the top of the lower chassis 1 and at the paper outlet position of the bottom of the upper chassis 2. A paper feeding device 5 and a paper sterilizing mechanism 7 are respectively installed inside the upper chassis 2.

[0040] like Figure 2-5As shown, the paper disinfection mechanism 7 is installed on the top of the paper feeding device 5, and the paper disinfection mechanism 7 includes a mounting frame 701 installed on the inner wall of the upper chassis 2, and a mounting plate 702 horizontally installed on the mounting frame 701, and a high-energy pulse ultraviolet lamp source 703 is installed at the central position of the mounting plate 702. It is further explained that in the entire device, the paper loading device 4, the paper feeding device 5 and the paper inlet and outlet at the bottom of the upper chassis 2 are on the same line, and the paper is manually placed on the paper loading device 4, and the paper is transported from the paper loading device 4 to the paper feeding device 5 at a high speed. The paper feeding device 5 transfers the single paper from the paper inlet at the bottom of the upper chassis 2 to the paper outlet, and finally falls into the paper receiving tray 3. When the paper is translated and transported by the paper feeding device 5, the paper disinfection mechanism 7 quickly disinfects the paper.

[0041] Since the paper disinfection mechanism 7 adopts a high-energy pulse ultraviolet light source 703, this type of disinfection and sterilization light source equipment has a disinfection and sterilization effect far exceeding that of ordinary ultraviolet germicidal lamps. However, this light source will generate high heat during operation, and in order to avoid safety hazards caused by leakage of ultraviolet light, its upper chassis 2 adopts a closed and light-proof design to avoid damage to the light source caused by continuous high temperature. Figure 2-5 As shown, a heat dissipation system for dissipating heat for the paper disinfection mechanism 7 is installed inside the lower chassis 1. The heat dissipation system includes a coolant storage tank, a coolant heat exchanger 9 and a delivery pump 10 installed inside the lower chassis 1. The coolant heat exchanger 9 adopts a fin-tube heat exchanger. A fan is also installed on one side of the coolant heat exchanger 9. The inlet and outlet of the coolant heat exchanger 9 are respectively connected to the outlet of the coolant storage tank and the input end of the infusion pump through pipelines.

[0042] Among them, in order to cooperate with the disinfection system to complete the cooling of the light source equipment, a heat exchange device is installed inside the shell of the high-energy pulse ultraviolet lamp source 703; the inlet and outlet at both ends of the heat exchange device are connected with the output end of the delivery pump 10 in the heat dissipation system and the inlet of the coolant storage tank 8 through pipelines, and the delivery pump 10 is used to promote the coolant to form a closed-loop circulation in the heat dissipation system in conjunction with the pipeline. During the circulation process, the coolant is cooled by the coolant heat exchanger 9 and then transported to the heat exchange device inside the shell of the high-energy pulse ultraviolet lamp source 703 for heat exchange, and this cycle is repeated to achieve the purpose of continuously cooling the high-energy pulse ultraviolet lamp source 703.

[0043] In order to cooperate with the paper feeding mechanism to achieve the purpose of continuous paper transportation, such as Figure 6-7As shown, the paper feeding device 5 mainly includes a base and a paper feeding drive mechanism. The base is mainly composed of a square bracket 501 and a bottom support plate 502 installed on the bracket 501. Specifically, the paper feeding drive mechanism includes a wheel frame 503 installed in parallel on the top of the bottom support plate 502. The two ends of the wheel frame 503 are respectively rotatably installed with a transversely arranged rotating shaft A504 and a rotating shaft B505. In order to prevent the paper from shifting during transportation, it should be noted that the rotating shaft A504 and the rotating shaft B505 are parallel to the paper pickup wheel 405 in the paper loading device 4 described below.

[0044] Both ends of the rotating shaft A504 and the rotating shaft B505 are equipped with a paper feeding main wheel 507 and a linkage wheel 506. The linkage wheels 506 at both ends of the rotating shaft A504 and the rotating shaft B505 are connected by a linkage belt 508. The paper feeding drive mechanism also includes a paper feeding motor 509 and four paper feeding auxiliary wheels 513. The four paper feeding auxiliary wheels 513 are installed at the bottom of the bottom support plate 502 and correspond to the positions of the four paper feeding main wheels 507. Avoidance holes are opened at the positions corresponding to the four paper feeding main wheels 507 on the bottom support plate 502. The corresponding paper feeding auxiliary wheels 513 roll with the paper feeding main wheels 507 through the avoidance holes. The paper feeding motor 509 is installed on the wheel frame 503. On the side, a driving wheel 510 is installed on the driving shaft of the paper feeding motor 509, and a pressure wheel 511 rolling with the driving wheel 510 is also installed at the end of the paper feeding motor 509. The linkage belt 508 on the wheel frame 503 close to the paper feeding motor 509 is connected to the driving wheel 510 through the pressure wheel 511. In order to ensure the normal paper loading and transportation of paper, the interval between the rotating shaft A504 and the rotating shaft B505 is smaller than the length of A4 paper, and the interval between the two sets of paper feeding main wheels 507 on the rotating shaft A504 and the rotating shaft B505 is smaller than the width of A4 paper. The emergence of this design can make the paper transfer smoother.

[0045] In order to realize paper disinfection counting, a paper output monitoring sensor 512 is installed on the side of one end of the bottom support plate 502 close to the paper output port.

[0046] In order to realize automatic single-sheet feeding, such as Figure 6-7As shown, the paper loading device 4 includes a base 401, a slanted paper slot 402 is installed on the top of the base 401, a paper sorting slider 403 is slidably installed on the inner side of the paper slot 402, and a paper loading motor 404 is installed on the side of the paper slot 402, and the paper loading motor 404 is transmission-connected to a paper pickup wheel 405 installed at the bottom of the paper slot 402, wherein, in order to achieve the pick-up and delivery coordination between the paper loading device 4 and the paper feeding device 5, the wheel body of the paper pickup wheel 405 adopts a semicircular design, and the paper outlet at the bottom of the paper slot 402 is close to the rotating shaft B505 in the paper feeding device 5; a bracket 407 for supporting paper is also obliquely inserted on the back of the paper slot 402, and a paper feeding monitoring sensor 406 is installed on the side of the paper pickup wheel 405 to facilitate the user to perform disinfection work on the specified number of sheets according to needs and realize the intelligent control effect of paper loading.

[0047] Furthermore, a lower disinfection unit installation chamber 6 is formed between the bottom area of ​​the bottom support plate 502 and the top of the lower chassis 1; the bottom support plate 502 adopts a high-transmittance quartz glass plate; and the interior of the lower disinfection unit installation chamber 6 is equipped with a group of high-energy pulse ultraviolet lamp sources 703 according to actual disinfection needs, so as to achieve double-sided disinfection and sterilization of paper simultaneously, and it should be noted that after the high-energy pulse ultraviolet lamp source 703 is installed in the lower disinfection unit installation chamber 6, it is necessary to connect the newly added high-energy pulse ultraviolet lamp source 703 to the heat dissipation system through a pipeline.

[0048] like Figure 1-4 As shown, in order to facilitate the user to operate the device, a control panel (not shown) connected to the paper loading motor 404, the paper feeding motor 509, the paper feeding monitoring sensor 406, the paper output monitoring sensor 512, the high-energy pulse ultraviolet light source 703, and the heat dissipation system is installed on the top of the upper chassis 2; and a power supply 11 is also installed inside the lower chassis 1, and the power supply 11 is respectively electrically connected to the heat dissipation system, the high-energy pulse ultraviolet light source 703, the paper loading motor 404, the paper feeding motor 509, and the control panel and supplies power to them.

The adjustable installation design is realized between the two sides of the mounting plate 702 and the mounting frame 701 through the cooperation between the bolts and the mounting slots.
