Description

Technical Field

[0001] This invention relates to the field of disinfection technology, and in particular to a surface disinfection device. Background Technology

[0002] With the increasingly widespread application of packaging materials, turnover boxes, appliance shells, component surfaces, and various transferable items in medical and health, food packaging, logistics, and industrial manufacturing scenarios, the demand for continuous disinfection of object surfaces is gradually increasing. Especially in assembly line environments, workpieces to be processed often need to undergo surface disinfection, surface drying, or heat treatment during transport. Therefore, surface disinfection devices that can adapt to continuous transport cycles and provide stable treatment of workpiece surfaces have become an important development direction in related equipment fields.

[0003] In existing technologies, for continuous conveyor surface disinfection devices, disinfection lamps are usually installed on one side or above and below the conveyor channel, supplemented by components such as fans and heaters, so that the workpieces are irradiated and blown during the conveying process. Although some solutions have also attempted to set up air passage structures above and below the conveyor path, most of them are still simple superimposed layouts. The airflow has a single direction, uneven force, and limited coverage. For example, due to the obstruction and resistance of the workpiece itself, conventional airflow tends to have a strong force on one side, while the force on the side and back is very limited. The uneven force makes it difficult to form a stable and uniform disinfection environment around the workpiece surface when the workpiece passes through continuously. This can easily lead to inconsistent heating and disinfection effects on different surface areas of the workpiece, thus affecting the uniformity and stability of the overall surface disinfection treatment.

[0004] Therefore, it is necessary to improve the existing surface disinfection devices to solve the technical problem of limited coverage of the force applied to the workpiece surface. Summary of the Invention

A mounting frame is provided below the mounting plate, and multiple inclined support plates are provided between the mounting frame and the mounting plate. The multiple support plates are arranged around the mounting opening.

[0010] Optionally, the air guide assembly is disposed on the air outlet side of the second fan, and the air guide assembly includes an air guide port corresponding to the mounting port, and an air guide enclosure surrounding the air guide port.

[0011] Optionally, the heating assembly is provided in at least two sets, and the at least two sets of the heating assembly are respectively disposed at the air vent; The airflow amplification component is disposed at the air outlet end of the heating component. The airflow amplification component is provided with at least two sets of guide plates arranged circumferentially.

Along the direction from bottom to top, the cross-sectional area of ​​the airflow amplification channel gradually increases.

[0012] Optionally, the conveying mechanism includes a frame and a plurality of conveying rollers disposed on the frame, wherein the plurality of conveying rollers are arranged sequentially at intervals along the conveying direction and the axial directions of the plurality of conveying rollers are parallel to each other; The upper ends of the plurality of conveying rollers together form a conveying surface for carrying the workpiece, and an interval area is formed between two adjacent conveying rollers.

[0016] Compared with the prior art, the present invention has the following beneficial effects: During operation, the workpiece enters the disinfection space via the conveying mechanism along a preset conveying direction; after the first fan in the top control mechanism located above the conveying mechanism is started, a first air path is formed in the direction perpendicular to the conveying mechanism. The airflow is adjusted to a preset temperature after passing through the temperature control component on the first air path and acts on the upper surface area of ​​the workpiece from top to bottom; at the same time, the second fan in the lower control mechanism is started, the airflow flows towards the guide air component, and is guided and diffused by the flow expansion component in the second air path, wherein the guide plate in the flow expansion component is positioned relative to the direction of the first air path. The inclined posture at a preset angle causes the airflow in the second air path to change its flow direction and expand its range of action under the action of the guide plate. The heating component heats the airflow in the second air path, so that the lower control mechanism outputs airflow with heat diffusion characteristics. As a result, the hot airflow formed by the upper first air path and the hot airflow formed by the lower second air path converge around the workpiece and form thermal convection, performing cyclic heat exchange on the surface of the workpiece. At the same time, the side disinfection mechanism performs disinfection compensation on the side area of ​​the workpiece, thereby realizing continuous surface disinfection treatment of the workpiece during the conveying process and improving the uniformity and coverage of surface disinfection treatment.

[0021] To make the objectives, features, and advantages of this invention more apparent and understandable, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0022] In the description of this invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component positioned centrally in the connection.

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] Combination Figures 1 to 9 As shown, this embodiment of the invention provides a surface disinfection device, including a conveying mechanism 100, a top control mechanism 200 disposed at a preset position above the conveying mechanism 100, and a lower control mechanism 300 disposed opposite to the top control mechanism 200; a disinfection space is formed around the top control mechanism 200 and the lower control mechanism 300, and a side disinfection mechanism 400 is provided on at least one side of the disinfection space. The disinfection lamp of the side disinfection mechanism 400 in this solution can be an ultraviolet germicidal lamp. To avoid hot air affecting the operation of the disinfection lamp, the ultraviolet germicidal lamp is preferably a temperature-resistant model.

[0025] Specifically, the surface disinfection device adopts a continuous structural layout along the conveying direction. The conveying mechanism 100 forms the passage path for the workpiece. The top control mechanism 200 is set at a preset position above the conveying mechanism 100, and the lower control mechanism 300 is set below the conveying mechanism 100 and is set opposite to the top control mechanism 200 in the vertical direction, thereby forming a disinfection space in the middle area of ​​the conveying path for the workpiece to pass through continuously.

[0026] The side disinfection mechanism 400 is disposed on at least one side of the disinfection space, so that the disinfection space forms a processing area enclosed by at least three directions: top, bottom, and sides, during the passage of the workpiece. The "at least one side" can be any arrangement of one side, opposite two sides, or multiple adjacent sides of the workpiece conveying path, to accommodate workpieces of different shapes and sizes and with different surface exposure characteristics. Through this spatial layout, the workpiece can enter the disinfection space without stopping during transport and receive combined treatment from the top, bottom, and side areas during passage, which helps improve the spatial coverage integrity and processing stability under continuous operation.

[0027] The top control mechanism 200 includes a first fan 210, and a first air passage 201 formed by the first fan 210 is arranged perpendicular to the conveying mechanism 100. A temperature control component 220 is provided on the first air passage 201. The bottom control mechanism 300 includes a second fan 310 arranged opposite to the first fan 210. A guide component 320 is arranged facing the second fan 310. A heating component 330 and a flow-expanding component 340 are arranged sequentially on the second air passage 301 formed by the guide component 320. The flow-expanding component 340 includes a guide plate 341 that is inclined at a preset angle to the direction of the first air passage 201. The first air passage 201 and the second air passage 301 form a heat convection that acts on the surface of the workpiece.

[0028] It should be noted that the first fan 210 in the top control mechanism 200 forms the first air passage 201. The first air passage 201 is arranged vertically towards the conveying mechanism 100, so that the airflow acts on the upper surface area of ​​the workpiece from top to bottom. The temperature control component 220 on the first air passage 201 is used to regulate the temperature of the airflow so that the airflow entering the upper part of the disinfection space is kept at a preset temperature suitable for surface treatment.

[0029] The second fan 310 in the lower control mechanism 300 is arranged vertically opposite to the first fan 210. The airflow output by the second fan 310 is introduced into the second air path 301 through the air guide assembly 320. In the second air path 301, the airflow is first compensated for by the flow expansion assembly 340, and then the direction is adjusted and the flow field is expanded so that the airflow from below forms a hot airflow with diffusion characteristics when it is close to the bottom area of ​​the workpiece.

[0030] The guide plate 341 is inclined relative to the first air path 201, so that the second air path 301 does not form a simple vertical straight relationship with the first air path 201, but forms a heat convection path with converging and surrounding characteristics around the workpiece. As a result, the problem of insufficient local treatment or uneven surface heating that is prone to occur under the action of a single air direction can be alleviated, so that the surface of the workpiece can obtain a more uniform and stable heat exchange and disinfection effect when it is transported through the disinfection space.

[0031] The working principle of this invention is as follows: During operation, the workpiece enters the disinfection space via the conveying mechanism 100 along a preset conveying direction; after the first fan 210 in the top control mechanism 200 located above the conveying mechanism 100 is started, a first air path 201 is formed in the direction perpendicular to the conveying mechanism 100. The airflow is adjusted to a preset temperature after passing through the temperature control component 220 on the first air path 201, and acts on the upper surface area of ​​the workpiece from top to bottom; at the same time, the second fan 310 in the lower control mechanism 300 is started, the airflow flows towards the guide air component 320, and is guided and diffused in the second air path 301 by the flow expansion component 340, wherein the guide plate 341 in the flow expansion component 340 is positioned relative to the first The airflow path 201 is set at a preset angle, causing the airflow in the second airflow path 301 to change its flow direction and expand its range under the action of the guide plate 341. The heating component 330 heats the airflow in the second airflow path 301, thereby causing the lower control mechanism 300 to output airflow with heat diffusion characteristics. As a result, the hot airflow formed by the upper first airflow path 201 and the hot airflow formed by the lower second airflow path 301 converge around the workpiece and form heat convection, performing cyclic heat exchange on the surface of the workpiece. At the same time, the side disinfection mechanism 400 disinfects and compensates the side area of ​​the workpiece, thereby realizing continuous surface disinfection treatment of the workpiece during the conveying process and improving the uniformity and coverage of the surface disinfection treatment.

[0032] In this embodiment, there are two first fans 210, which are arranged side by side and spaced apart. The two first fans 210 are connected to a mounting plate 250, which has multiple air outlets. The lower end face of the mounting plate 250 is provided with at least one set of temperature control components 220. The temperature control components 220 include a first housing 221 and a heating tube disposed in the first housing 221. The upper end face of the first housing 221 is provided with an opening that connects with the air outlets, and the lower end face of the first housing 221 is provided with an air outlet for air discharge, which has filter holes.

[0033] Specifically, the temperature control component 220 located on the lower end face of the mounting plate 250 forms a vertical connection with the corresponding air outlet. This allows the airflow to enter the first housing 221 from the air outlet, contact the heating tube inside the first housing 221, complete heat exchange within the first housing 221, and then exit from the lower air outlet. Because the first housing 221 adopts a vertically continuous structure with an upper opening for air intake and a lower air outlet for air exhaust, the first air path 201 can form a relatively clear vertical guiding path within the top control mechanism 200. Simultaneously, the filter holes on the air outlet not only form a mesh-like dispersion structure in the air outlet area but also help to homogenize the airflow discharged from the temperature control component 220 to a certain extent before entering the space below. This results in a more stable downward coverage of the airflow output by the top control mechanism 200, which is beneficial for subsequently forming a uniform heat treatment area facing the upper surface of the workpiece.

[0034] In this embodiment, each first fan 210 is further provided with two sets of spaced temperature control components 220, and the air outlets of the two sets of temperature control components 220 respectively form a hot air duct; a spacer 230 is formed between the two sets of temperature control components 220, and the spacer 230 has an air outlet to form a normal temperature air duct.

[0035] Below the temperature control component 220 is a flow guiding component 240, which includes a straight opening 241 and flow guiding surfaces 242 on both sides of the straight opening 241. The distance between the two flow guiding surfaces 242 gradually decreases from top to bottom. The hot air duct corresponds to the flow guiding surface 242, and the normal temperature air duct corresponds to the straight opening 241, so that the hot air duct and the normal temperature air duct converge.

[0036] It should be noted that two sets of spaced-apart temperature control components 220 are installed below each first fan 210, so that the top control mechanism 200 does not form a single, integral hot air column when discharging downwards, but rather forms two relatively separate hot air ducts on both sides, with a gap 230 maintained between the two sets of temperature control components 220 to form a normal temperature air duct in the central area. This "hot air on both sides, normal temperature in the middle" airflow layout gives the airflow output by the top control mechanism 200 a differentiated distribution characteristic before entering the space below.

[0037] The airflow guiding component 240, located below the temperature control component 220, further integrates the airflow. The straight inlet 241 corresponds to the normal temperature air duct, and the two airflow guiding surfaces 242 correspond to the two hot air ducts respectively. The distance between the two airflow guiding surfaces 242 gradually decreases from top to bottom, so that the hot air ducts on both sides gradually converge towards the central region during the downward process and converge with the normal temperature air duct that is led down through the straight inlet 241.

[0038] This structural arrangement allows the originally separate hot air duct and normal temperature air duct to form a composite airflow near the upper area of ​​the workpiece. On the one hand, it helps to improve the problem of excessive local heat concentration when a single hot air is directly pressed down. On the other hand, it also helps to improve the coverage balance of the downward airflow of the top control mechanism 200 in the width direction, thereby making the thermal convection formed by the cooperation of the upper and lower air ducts more stable.

[0039] Since conventional heating elements have a relatively high lower temperature limit, if hot air is used alone, it is easy for high-temperature hot air to act on the side disinfection mechanism 400 on the side wall, affecting the operation of the disinfection lamp 420. To avoid this situation, a method of combining normal temperature air duct and hot air duct is adopted to achieve thermal balance.

[0040] In this embodiment, the second fan 310 includes a mounting plate 311, a circular mounting opening 312 is provided on the mounting plate 311, an annular enclosure is formed on the inner circumference of the circular mounting opening 312, and a plurality of fan blades 313 are provided in the circular mounting opening 312 at intervals along the circumference.

[0041] Below the mounting plate 311 is a mounting bracket 314. Between the mounting bracket 314 and the mounting plate 311 are multiple inclined support plates 315. The multiple support plates 315 are arranged around the mounting opening. Between the mounting bracket 314 and the mounting plate 311 is a drive component 316 located at the center of multiple fan blades 313. The drive end of the drive component 316 is connected to the multiple fan blades 313.

[0042] Specifically, the second fan 310 adopts an assembly structure consisting of a mounting plate 311, a mounting bracket 314, a support plate 315, a fan blade 313, and a drive component 316. The mounting plate 311 serves as the upper mounting base of the second fan 310, and the circular mounting port 312 is used to define the main air outlet area of ​​the second fan 310. The annular enclosure formed on the inner circumference of the circular mounting port 312 forms a circumferential enclosure on the rotation area of ​​the fan blade 313, so that the airflow output when the fan blade 313 rotates can be concentrated and discharged along the corresponding area of ​​the mounting port.

[0043] The mounting bracket 314 is located below the mounting plate 311, and the driving component 316 is located at the center of the multiple fan blades 313, so that the fan blades 313 form a rotating structure driven around the center in the circumferential direction, thereby enabling the airflow output by the second fan 310 to form a relatively concentrated upward airflow in the mounting port area.

[0044] In this embodiment, the air guide assembly 320 is disposed on the air outlet side of the second fan 310. The air guide assembly 320 includes an air guide port 321 corresponding to the installation port, and an air guide enclosure 322 disposed around the air guide port 321.

[0045] It should be noted that the air guide plate 322 surrounding the air guide 321 defines the outer contour of the second air passage 301, keeping the airflow output by the second fan 310 within a relatively confined flow channel before entering the subsequent structure. Preferably, the air guide plate 322 can be continuously arranged along the extension direction of the second air passage 301, or formed by splicing multiple plate segments, so that the air guide assembly 320 structurally forms a transitional flow guiding area between the second fan 310 and the flow expansion assembly 340. With this arrangement, the airflow output by the second fan 310 can be rectified and path-limited by the air guide assembly 320 after leaving the fan blade 313 area, which helps to improve the flow direction stability of the front section of the second air passage 301 and reduce the occurrence of flow deviation and turbulence in the lower airflow when it is first output.

[0046] In this embodiment, it is further explained that the heating component 330 is provided with at least two sets, and the at least two sets of heating components 330 are respectively disposed at the air guide 321; the flow expansion component 340 is disposed at the air outlet end of the heating component 330, and the flow expansion component 340 is provided with at least two sets of guide plates 341 arranged circumferentially, and the at least two sets of guide plates 341 are arranged around the second air passage 301 to form an air expansion channel, and the cross-sectional area of ​​the air expansion channel gradually increases along the direction from bottom to top.

[0047] It should be noted that the airflow expansion component 340 is disposed at the air outlet end of the heating component 330, and is arranged around the second air passage 301 by at least two sets of guide plates 341 arranged circumferentially, so as to form multiple airflow expansion channels between adjacent guide plates 341; wherein, the cross-sectional area of ​​each airflow expansion channel gradually increases from bottom to top, so that the airflow gradually expands outward from a relatively concentrated flow bundle state during the upward process.

[0048] This gradually expanding flow channel structure means that the second air path 301 does not directly rush towards the bottom of the workpiece with a single column of air, but gradually expands its coverage area during the upward process, which helps to reduce the situation of excessive wind speed and heat concentration in local areas. At the same time, multiple circumferentially distributed air expansion channels can also make the airflow from the second fan 310 disperse and spread in the circumferential direction, so as to form a more balanced distribution of hot airflow in the bottom area of ​​the workpiece, and together with the first air path 201 above, form a more stable convection treatment environment.

[0049] In this embodiment, the conveying mechanism 100 includes a frame 110 and a plurality of conveying rollers 120 disposed on the frame 110. The plurality of conveying rollers 120 are arranged sequentially at intervals along the conveying direction, and the axial directions of the plurality of conveying rollers 120 are parallel to each other. The upper ends of the plurality of conveying rollers 120 together form a conveying surface for carrying the workpiece. An interval area 130 is formed between two adjacent conveying rollers 120. The lower control mechanism 300 is at least partially disposed corresponding to the interval area 130.

[0050] Specifically, the conveying mechanism 100 adopts a roller-type conveying structure in which a frame 110 cooperates with multiple conveying rollers 120. The multiple conveying rollers 120 are arranged sequentially at intervals along the conveying direction and are set on the frame 110 with a parallel axial relationship, thereby forming a continuously extending conveying surface on the upper part of the conveying mechanism 100. This structure can provide stable rolling support for the workpiece, allowing the workpiece to continuously pass through the disinfection space in a preset direction. On the other hand, the interval area 130 formed between two adjacent conveying rollers 120 provides structural space for the arrangement of the lower control mechanism 300, allowing at least a part of the lower control mechanism 300 to be set from below corresponding to the interval area 130. As a result, the second air passage 301 output by the lower control mechanism 300 can act towards the bottom area of ​​the workpiece through the interval area 130, thereby reducing the obstruction of the lower air passage and the lower processing area by the conveying components, and facilitating the formation of an upper and lower convection processing state in conjunction with the upper first air passage 201.

[0051] In this embodiment, it is further explained that the side disinfection mechanism 400 includes a mounting base 410, which extends along the conveying direction of the conveying mechanism 100, and a disinfection lamp 420 is provided on the mounting base 410; the side disinfection mechanism 400 is provided with at least two sets, and the at least two sets of side disinfection mechanisms 400 are respectively provided on opposite sides of the disinfection space, and multiple disinfection lamps 420 are arranged facing the disinfection space.

[0052] The side disinfection mechanism 400 uses a mounting base 410 extending along the conveying direction as its mounting foundation, and disinfection lamps 420 are arranged on the mounting base 410, so that the side disinfection mechanism 400 forms a lateral processing unit that unfolds along the workpiece conveying path in terms of structure. After at least two sets of side disinfection mechanisms 400 are respectively arranged on opposite sides of the disinfection space, they can perform corresponding treatment on the side walls, edges or corner areas of the workpiece from the left and right sides when the workpiece passes through the disinfection space.

[0053] Preferably, the mounting base 410 can be continuously arranged along the side of the disinfection space, or it can be formed by splicing multiple segmented bases to adapt to processing areas of different lengths. Through this double-sided opposing structure, the side disinfection mechanism 400, together with the top control mechanism 200 and the lower control mechanism 300, can form a multi-directional surrounding processing layout, which is beneficial to improving the overall spatial coverage of the outer surface of the workpiece, especially to improving the problem of insufficient processing in the side area.

[0054] In this embodiment, the surface disinfection device further includes an entrance gate 500 and an exit gate 600 disposed on both sides of the disinfection space. The entrance gate 500 is disposed at the input end of the conveying mechanism 100 and located on the entrance side of the disinfection space, and the exit gate 600 is disposed at the output end of the conveying mechanism 100 and located on the exit side of the disinfection space. The entrance gate 500 and the exit gate 600 each include a support frame 510 and a gate assembly 520 disposed on the support frame 510. The gate assembly 520 is disposed across the conveying mechanism 100 to define the entrance boundary and the exit boundary of the disinfection space, respectively.

[0055] The two gates are respectively installed on both sides or above the conveying mechanism 100 via support frames 510, and the front and rear boundaries of the disinfection space are defined by gate components 520 spanning the conveying mechanism 100. This arrangement gives the disinfection space relatively clear entry and exit zones in the conveying direction, which helps to place the workpiece in a relatively independent processing area after entering the disinfection space. Furthermore, the inlet gate 500 and the outlet gate 600 can be opened and closed in coordination according to the conveying rhythm and the workpiece passage status to reduce the interference of external ambient air on the airflow organization inside the disinfection space, and to help maintain a relatively stable thermal convection and lateral processing environment inside the disinfection space.

[0056] In this embodiment, the gate assembly 520 of the outlet gate 600 includes a roller shutter door 530 and a retracting part disposed above the mounting frame 314. The upper end of the roller shutter door 530 is connected to the retracting part. The mounting frame 314 has guide parts disposed opposite to each other on both sides. The roller shutter door 530 is located between the two guide parts and is raised and lowered along the extension direction of the guide parts.

[0057] It should be noted that the upper end of the roller shutter door 530 is connected to the retracting section located above the mounting frame 314, enabling the roller shutter door 530 to be rolled up and lowered under the action of the retracting section. The guide sections on both sides of the mounting frame 314 provide lateral limiting and guidance for the roller shutter door 530, allowing it to move along a preset trajectory during lifting and lowering. When this roller shutter structure is arranged on the exit side, it occupies less lateral space overall, and the roller shutter door 530 can be rolled up upwards to the upper area of ​​the exit gate 600 after opening, thereby reducing the obstruction to the conveying path and the workpiece output path. At the same time, when the roller shutter door 530 is lowered to the closed position, it can form a relatively complete vertical shielding relationship with the exit side boundary, which is beneficial for defining the boundary of the rear end of the disinfection space and improving the stability of the internal environment of this area before the workpiece leaves the disinfection space.
