Description

Technical Field

[0001] This utility model belongs to the field of 3C metal parts processing technology, specifically relating to a brush roller spraying device for a cleaning machine. Background Technology

[0002] In industrial metal processing, metal grinding helps remove surface defects, oxide layers, and other contaminants to ensure the precision and smoothness of metal parts. However, grinding generates a large amount of metal shavings, dust, and abrasive residue. If these contaminants are not removed promptly, they will seriously affect the quality of metal parts and subsequent processing. Currently, the main methods for removing dust from metal surfaces are chemical methods, electrolytic methods, and manual cleaning. Manual cleaning is inefficient and difficult to perform on complex parts. Electrolytic methods are prone to over-etching, and the bath solution has a short service life. Traditional chemical methods use strong acids and strong oxidants, which affect the health of operators and cause significant environmental pollution.

[0003] A single-sided brush roller cleaning machine disclosed in patent CN107931199A includes a brush roller driven by a transmission gear. Both the brush roller and the transmission gear are mounted on a frame. A front belt roller and a rear belt roller are mounted at both ends of the frame, driving a conveyor belt. The frame is equipped with a touch screen, which controls a first frequency converter and a second frequency converter via a control bus. The first and second frequency converters drive a first motor and a second motor, respectively. The first motor drives the transmission gear via a first chain, and the second motor drives the rear belt roller via a second chain, a double gear, and a third chain. This invention has a reasonable structure. The material is conveyed by the conveyor belt, cleaned by the brush roller, and output through the feeding nozzle. By changing the speed of the first and second motors via the touch screen, different cleaning efficiencies and cleaning effects can be achieved.

[0004] In the above scheme, the conveyor belt is tensioned and driven by two front and rear rollers, forming an operation mode in which the upper layer carries the workpiece and the lower layer rotates and circulates. However, the sewage after the upper layer is cleaned will contaminate the rotating lower layer conveyor belt when it falls, and the constantly moving lower layer conveyor belt will carry the sewage to other parts of the device, causing pollution. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems by providing a brush roller spraying device for a cleaning machine that can solve the above-mentioned technical issues.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: The brush roller spraying device of the cleaning machine includes a support frame, on which a circulating transport chain is provided. A part of the transport chain is located in the cleaning passage. Several spraying components are arranged on the upper and lower sides of the transport chain in the cleaning passage. A spray liquid recovery container is correspondingly arranged below the spraying components. Another part of the transport chain passes under the spray liquid recovery container.

[0007] In the brush roller spraying device of the cleaning machine, the support frame is rotatably equipped with transmission gears at both ends of the cleaning passage, the transport transmission chain is meshed with the two transmission gears, and the transmission gears are coaxially equipped with an input gear that is connected to the drive motor.

[0008] In the brush roller spraying device of the cleaning machine, the transport drive chain includes a loaded section between the two drive gears and an unloaded section for the remainder. The loaded section is located in the cleaning passage, and the unloaded section is guided by a tensioning assembly disposed on the support frame to pass under the spray liquid recovery container.

[0009] In the brush roller spraying device of the cleaning machine, the tensioning component includes fixed tensioning gears disposed on both sides of the spray liquid recovery container, and an adjusting tensioning gear located between the transmission gear and the fixed tensioning gear. The horizontal height of the fixed tensioning gear is lower than the bottom surface of the spray liquid recovery container.

[0010] In the brush roller spraying device of the cleaning machine, the support frame is provided with a slide groove for the slider to move laterally, the rotating shaft of the adjusting tension gear is rotatably mounted on the slider, the slider moves laterally in the slide groove provided in the support frame, and is threadedly connected to the support frame through a rotatable adjusting screw.

[0011] In the brush roller spraying device of the cleaning machine, the operation sequence of the cleaning passage includes a feeding section and a cleaning section in sequence, and a plurality of spraying components are arranged on the upper and lower sides of the transport transmission chain of the cleaning section and spray liquid recovery containers are arranged below them.

[0012] In the brush roller spraying device of the cleaning machine, the spraying assembly includes a spray pipe and spray nozzles radially arranged on the spray pipe. The spray pipe is connected to a pump, and the spray nozzles face the conveyor chain.

[0013] In the brush roller spraying device of the cleaning machine, the upper spray nozzle sprays perpendicularly to the transport drive chain, and the western spray nozzle sprays at an angle toward the direction of travel of the transport drive chain.

[0014] In the brush roller spraying device of the cleaning machine, a protective shell is provided over the cleaning passage, and a number of brush rollers are provided on the protective shell above the transport transmission chain. The brush rollers are driven by a brush roller motor in the forward direction of the transport transmission chain.

[0015] In the brush roller spraying device of the cleaning machine, there is a corresponding spraying component above each of the brush rollers.

[0016] The advantages of this utility model are: The lower side of the support frame is also equipped with multiple tension gears to guide the movement of the transport chain, so that the transport chain coming out of the cleaning passage passes under the spray liquid recovery container, avoiding the spray wastewater flowing down from the cleaning section in the cleaning passage. This prevents the transport chain from being re-contaminated during the rotation process and avoids wastewater being carried to other parts of the equipment by the lower transport chain, causing pollution.

Detailed Implementation

[0023] The following are specific embodiments of the utility model, which are described in conjunction with the accompanying drawings to further illustrate the technical solution of the utility model. However, the utility model is not limited to these embodiments.

[0024] like Figures 1-5As shown, the brush roller spraying device of the cleaning machine includes a support frame 1, on which a circulating transport chain 11 is provided. A part of the transport chain 11 is located in the cleaning passage. Several spraying components 2 are distributed on the upper and lower sides of the transport chain 11 in the cleaning passage. A spray liquid recovery container 12 is correspondingly provided below the spraying components 2. The other part of the transport chain 11 passes under the spray liquid recovery container 12.

[0025] In other words, the transport chain in the cleaning path carries the workpiece from the loading section through the cleaning section, cleaning the dust and fingerprints from the workpiece surface. The spray assembly sprays cleaning fluid and rinses the workpiece on the transport chain from both the top and bottom, while the recovery container below the cleaning section collects the sprayed fluid for reuse. The return section of the transport chain avoids the area where the sprayed fluid falls, bypassing the recovery container to prevent secondary contamination.

[0026] In this embodiment, a transmission gear 13 is rotatably mounted on the support frame 1 at both ends of the cleaning passage. The transport transmission chain 11 is meshed with the two transmission gears 13. An input gear 15 is coaxially mounted on the transmission gear 13 and is connected to the drive motor 14.

[0027] The two transmission gears are positioned at both ends of the cleaning passage, enabling the transmission chain of the cleaning section that needs to carry the workpiece to have more efficient power. Furthermore, the tensioning device on the return section of the transmission chain allows the transmission chain to operate continuously.

[0028] The drive motor can be installed on the transmission gear near the feeding section or on the transmission gear near the cleaning section.

[0029] In this embodiment, the transport transmission chain 11 includes a loaded section between two transmission gears 13 and an unloaded section for the remainder. The loaded section is located in the cleaning passage, and the unloaded section is guided by a tensioning assembly 3 disposed on the support frame 1 to pass under the spray liquid recovery container 12.

[0030] The loaded section carries the workpiece and is sprayed with cleaning fluid and washed with clean water from the brush rollers. Therefore, in order to keep the unloaded section clean during the return process, the unloaded section is guided by the tensioning assembly to pass under the recovery container.

[0031] In this embodiment, the tensioning assembly 3 includes a fixed tensioning gear 31 disposed on both sides of the spray liquid recovery container 12, and an adjusting tensioning gear 32 located between the transmission gear 13 and the fixed tensioning gear 31. The fixed tensioning gear 31 is horizontally lower than the bottom surface of the spray liquid recovery container 12.

[0032] The fixed tension gear determines the meshing connection fulcrum on both sides of the spray liquid recovery container, so that the unloaded section of the transmission chain forms a stroke that goes around the upper side of the spray liquid recovery container, and the transmission chain is tightened by the fixed tension gear on the load section side near the input gear, so that the coaxial transmission gear outputs more efficient power to the transmission chain.

[0033] In this embodiment, the support frame 1 is provided with a slide groove 34 for the slider 33 to move laterally. The rotating shaft of the tensioning gear 32 is rotatably mounted on the slider 33. The slider 33 moves laterally in the slide groove 34 provided in the support frame 1 and is threadedly connected to the support frame 1 through a rotatable adjusting screw 35.

[0034] The upper and lower walls of the slide block abut against the slider, leaving only lateral space for the slider to move. At the same time, a self-rotating screw is installed on the slider and threadedly connected to the side wall of the slide block. By rotating the screw, the distance between the slider and the transmission gear is changed, thereby adjusting the tension of the transmission chain.

[0035] In this embodiment, the operation sequence of the cleaning passage includes a feeding section and a cleaning section in sequence. Several spraying components 2 are arranged on the upper and lower sides of the transport transmission chain 11 of the cleaning section and spray liquid recovery containers 12 are arranged below them.

[0036] The workpiece is placed on the conveyor chain from the loading section and enters the cleaning section with the transmission chain. First, the spray assembly sprays cleaning agent from the top and bottom, and then the spray assembly sprays rinsing water to remove the cleaning agent. The spray liquid recovery container at the bottom collects the washed-off cleaning agent, which can be reused after treatment.

[0037] In this embodiment, the spray assembly 2 includes a spray pipe 21 and spray nozzles 22 radially disposed on the spray pipe 21. The spray pipe 21 is connected to the pump 23, and the spray nozzles 22 face the transport drive chain 11.

[0038] The pump draws in the cleaning fluid, which is collected through the spray pipe and then evenly sprayed onto the upper and lower surfaces of the workpiece from each spray nozzle. The cleaning fluid is then rinsed with water by the subsequent spray assembly to clean the surface of the workpiece.

[0039] In this embodiment, the upper spray nozzle 22 sprays perpendicularly to the transport chain 11, while the western spray nozzle 22 sprays at an angle toward the direction of travel of the transport chain 11.

[0040] The upper spray nozzles spray vertically to ensure even coverage, while the lower spray nozzles need to be deflected at a certain angle to avoid obstructing the dripping cleaning liquid and achieve a uniform spray area.

[0041] In this embodiment, a protective shell 16 is provided over the cleaning passage, and several washing brush rollers 24 are provided on the protective shell 16 above the transport transmission chain 11. The washing brush rollers 24 are driven by the brush roller motor 25 in the direction of running of the transport transmission chain 11.

[0042] In the spray rinsing water section, a scrubbing roller that rotates in the same direction as the drive chain is also installed. The rotation speed of the scrubbing roller is different from the travel speed of the workpiece, so that the scrubbing roller can wash the surface of the workpiece together with the rinsing water to remove oil and dust.

[0043] In this embodiment, each brush roller 24 has a corresponding spray assembly 2 above it.

[0044] The upper spray assembly sprays rinsing water onto the brush roller to wet it, while the continuous flow of rinsing water from top to bottom reduces damage to the workpiece surface caused by the brush roller. The lower spray assembly rinses the wastewater that hangs and collects on the lower side of the workpiece.

[0045] The aforementioned drive motor and brush roller motor were both purchased commercially.

[0046] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
