Description

Technical Field

[0001] This application relates to the field of automotive seat leather, and more specifically, to a leather antibacterial and anti-mite treatment device. Background Technology

[0002] Car seat leather is in a closed, warm and humid environment inside the car for a long time, which makes it easy for bacteria and mites to grow. Their excrement may also cause allergies and harm the health of drivers and passengers. With the rise of the demand for "healthy cabin", consumers have paid more attention to the antibacterial and anti-mite performance of seat leather. Antibacterial and anti-mite treatment devices are needed in the production and processing of car seat leather.

[0003] Currently, antibacterial and anti-mite treatment devices typically use spraying antibacterial agents to treat the leather surface. However, the effect of antibacterial agents is mostly limited to the surface of the leather and cannot effectively penetrate into the leather fiber layer and deep crevices. They cannot reach the adult mites, eggs, and deep-seated bacteria hidden within. These unremoved organisms will continue to multiply, resulting in short-lived and recurring antibacterial and anti-mite effects. At the same time, mite excrement (allergens) mostly exist on the leather surface in the form of solid deposits. Antibacterial agents can only kill bacteria and mites and do not have the ability to physically remove them. These residual allergens will remain on the leather surface for a long time and may easily trigger allergic reactions in people during subsequent use. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] The purpose of this application is to address the shortcomings of existing technologies by providing a leather antibacterial and anti-mite treatment device. This addresses the problem that existing technologies generally use spraying antibacterial agents to achieve antibacterial and anti-mite treatment on the leather surface. However, the effect of antibacterial agents is mostly limited to the leather surface and cannot effectively penetrate into the leather fiber layer and deep crevices. They cannot reach the adult mites, mites, and bacteria hidden within. These unremoved organisms will continue to reproduce, resulting in short-lived and recurring antibacterial and anti-mite effects. At the same time, mite excrement (allergens) mostly exist on the leather surface in the form of solid attachments. Antibacterial agents can only kill bacteria and mites and do not have the ability to physically remove them. These residual allergens will remain on the leather surface for a long time, which may easily cause allergic reactions in humans during subsequent use.

[0006] To achieve the above objectives, this application provides the following technical solution:

[0007] A leather antibacterial and anti-mite treatment device includes: a treatment box, with assembly frames fixed at the front and rear ends of the treatment box, and a unwinding roller installed in the middle of the front assembly frame and a winding roller installed in the middle of the rear assembly frame; guide rollers are provided on both sides of the middle of the treatment box; a physical cleaning mechanism is provided on one side of the middle of the treatment box; a tensioning mechanism is provided in the middle section of the middle of the treatment box; a liquid pipe is provided on one side of the outer side of the treatment box, and a liquid distribution pipe is connected to the end of the liquid pipe; spraying frames are connected to both ends of the liquid distribution pipe; a fan is fixedly installed on one side of the outer side of the treatment box, and a heating box is installed on the outside of one end of the fan; convection ventilation filters are provided at the outer opening of the heating box and the opposite opening on the other side of the treatment box; the physical cleaning mechanism includes a cleaning component, which is located inside the treatment box; the cleaning component includes a pair of first guide frames, and a suction component is installed on the same side of the pair of first guide frames.

[0008] Furthermore, the cleaning component includes a first preset slot, which is located on both sides of one side of the processing box. A first motor is installed at the top of one of the first preset slots, and the output end of the first motor is connected to a positive and negative lead screw. First lead screw sleeves are screwed on both sides of the middle section of the positive and negative lead screws, and a first guide frame is fixed on the same side of the two first lead screw sleeves. A first guide rod is fixed in the middle of the other first preset slot. Fixing blocks are fixed on both sides of the opposite ends of the two first guide frames, and a brush roller is provided in the middle of the two pairs of fixing blocks. A second motor is installed at the same end of the two brush rollers.

[0009] Furthermore, the first guide rod is vertically connected to its two opposite first guide frames.

[0010] Furthermore, the suction assembly includes connecting blocks, which are respectively disposed on both sides of a pair of first guide frames. The ends of the two pairs of connecting blocks are fixedly connected to oppositely arranged vacuum cleaner frames, and the opposite ends of the pair of vacuum cleaner frames are equipped with vacuum cleaner covers. The same end of the pair of vacuum cleaner frames is connected to a secondary vacuum cleaner pipe, and the opposite ends of the pair of secondary vacuum cleaner pipes are connected to a telescopic hose. The opposite ends of the two telescopic hoses are connected to a three-way air pipe, and the other end of the three-way air pipe is connected to a main vacuum cleaner pipe.

[0011] Furthermore, the main suction pipe is connected to the secondary suction pipe and the corresponding suction frame via a three-way air pipe, two sets of telescopic hoses, and the suction frame.

[0012] Furthermore, the tensioning mechanism includes a second preset groove, which is located on both sides of the middle section inside the processing box. A third motor is installed above the interior of one of the second preset grooves, and the output end of the third motor is connected to a transmission screw. A second screw sleeve is screwed around one side of the transmission screw, and a second guide frame is fixed at the inner end of the second screw sleeve. A second guide rod is fixed in the middle of the other second preset groove, and a tensioning roller is installed below the second guide frame.

[0013] Furthermore, the tensioning roller is connected to the second guide frame and the second guide rod to form a lifting guide connection.

[0014] The beneficial effects of this application are as follows:

[0015] When processing automotive seat leather, the operator can activate the drive motor at one end of the take-up roller. The leather roll on the unwind roller will then be sequentially wound up under the guidance of two sets of guide rollers and a tension roller. During this process, the operator can pre-activate the first motor to rotate the lead screws. The pair of first lead screw sleeves, threaded with the lead screws, will move closer together, guided by their respective fixed first guide frames and the first guide rods. This allows the brush rollers, positioned on opposite sides of the first guide frames, to precisely adhere to the upper and lower surfaces of the leather. Driven by the second motors at their respective ends, the brush rollers pre-brush the upper and lower surfaces of the leather, using the physical friction of the bristles to remove mites from the leather surface and fiber layer, eliminating mite eggs and impurities. Simultaneously, the industrial vacuum cleaner connected to the end of the main suction pipe is activated. The suction power generated by the vacuum cleaner passes through the three-way air hose and a pair of telescopic hoses. The suction power is transmitted to the corresponding suction hoods through the connection between the suction pipe and the suction frame. The suction end of the pair of suction hoods is directly opposite the peeling surface of the pair of brush rollers and the working leather section. Thus, the suction can directly act on the peeled mites and impurities, effectively improving the cleanliness of the leather. Then, the leather will continue to be conveyed through the middle of the pair of spray racks. At this time, the liquid pump connected to one end of the liquid pipe is activated. The liquid in the liquid tank (pool, box, etc.) containing antibacterial liquid is guided to the distribution pipe through the pipe connected to the other end of the liquid pump until it is evenly sprayed from the spray heads set opposite the working surface of the pair of spray racks, thereby improving the antibacterial and mite removal effect. Next, the heating wire in the heating box is activated to provide a heat source. Then, the fan is activated to generate airflow to the heat source. Under the guidance and dust filtering effect of the convection ventilation filter set on the outside of the heating box and the side of the processing box, the heat source can be evenly guided to the upper and lower surfaces of the sprayed leather, thereby improving the drying effect and preventing bacteria from growing after the leather is rolled up in a damp state.

[0016] Workers can adjust the height of the tension roller corresponding to the leather according to the tension of the leather. The specific adjustment method is as follows: the worker starts the third motor to rotate the transmission screw. At this time, the second screw sleeve, which is threaded with the transmission screw, will drive the second guide frame and the tension roller set below. With the guidance of the second guide rod, the roller moves up and down, thereby achieving the purpose of adjusting the tension of the leather. Attached Figure Description

A convection ventilation filter 13 is provided at the side opening and the opposite opening on the other side of the processing box 1. The physical cleaning mechanism 6 includes a cleaning component 61, which is located inside the processing box 1. The cleaning component 61 includes a first preset groove 611, which is located on both sides of the inside of the processing box 1. A first motor 612 is provided at the top of one of the first preset grooves 611, and the output end of the first motor 612 is connected to a positive and negative lead screw 613. First lead screw sleeves 614 are screwed on both sides of the middle section of the positive and negative lead screw 613, and a first guide bracket 615 is fixed on the same side of the two first lead screw sleeves 614. A first guide rod 616 is fixed in the middle of the other first preset groove 611. A guide frame 615 has fixed blocks 617 on both sides of its opposite ends, and a brush roller 619 is provided in the middle of the two pairs of fixed blocks 617. A second motor 618 is installed at the same end of the two brush rollers 619. A first guide rod 616 is vertically connected to the two opposite first guide frames 615. A suction assembly 62 is installed on the same side of the pair of first guide frames 615. The suction assembly 62 includes connecting blocks 621, which are respectively located on both sides of one side of the pair of first guide frames 615. The ends of the two pairs of connecting blocks 621 are fixedly connected to oppositely arranged vacuum cleaner frames 622. A vacuum hood 623 is installed at the opposite ends of the pair of vacuum cleaner frames 622. A vacuum secondary pipe 624 is connected to the same end of the pair of vacuum cleaner frames 622. A pair of secondary suction hoses 624 are connected to telescopic hoses 625 at opposite ends. Two telescopic hoses 625 are connected to a three-way air hose 626 at opposite ends. The other end of the three-way air hose 626 is connected to a main suction hose 627. The main suction hose 627 is connected to the three-way air hose 626, the two sets of telescopic hoses 625, the secondary suction hoses 624, the suction frame 622, and the corresponding suction frame 622. When processing automotive seat leather, the operator can start the drive motor at one end of the take-up roller 4. The leather roll on the unwind roller 3 will then be sequentially wound up under the guidance of two sets of guide rollers 5 and a tension roller 77. During this process, the operator can pre-start the first motor 612 to rotate the forward and reverse lead screws 613.At this time, the pair of first screw sleeves 614, which are threaded with the positive and negative screws 613, will move relatively close to each other with their respective fixed first guide brackets 615 and the guiding action of the first guide rods 616. Thus, the brush rollers 619, which are respectively set on opposite sides of the pair of first guide brackets 615, can accurately adhere to the upper and lower surfaces of the leather. At this time, the pair of brush rollers 619 can pre-brush the upper and lower surfaces of the leather under the drive of the second motors 618 at their respective ends. Relying on the physical friction of the bristles, they peel off mites from the surface of the leather and the fiber layer, and remove mite eggs and impurities hidden therein. At the same time, the industrial vacuum cleaner connected to the end of the main suction pipe 627 is started. The suction power generated by the vacuum cleaner can be transmitted to the corresponding section of the vacuum hood 623 through the connection of the three-way air pipe 626, the pair of telescopic hoses 625, the secondary suction pipe 624 and the vacuum frame 622. The suction end of the pair of vacuum hoods 623 Directly facing the peeling surface of the pair of brush rollers 619 and the working leather section, the suction can directly act on the peeled mites and impurities, effectively improving the cleanliness of the leather. The leather then continues to be conveyed through the middle of the pair of spray racks 10. At this time, the liquid pump connected to one end of the liquid pipe 8 is activated, guiding the liquid in the tank (pool, box, etc.) containing antibacterial liquid to the distribution pipe 9 through the pipe connected to the other end of the pump, until it is evenly sprayed from the spray nozzles of the pair of spray racks 10 opposite the working surface, thereby improving the antibacterial and mite-removing effect. Next, the heating wire in the heating box 12 is activated to provide a heat source, and the fan 11 is activated to generate airflow to the heat source. Under the guidance and dust filtering effect of the convection ventilation filter 13 set on the outside of the heating box 12 and on one side of the processing box 1, the heat source can be evenly guided to the upper and lower surfaces of the sprayed leather, thereby improving the drying effect and preventing bacteria from growing after the leather is rolled up in a damp state.

[0031] It should be noted that the industrial vacuum cleaner and liquid pump mentioned in this solution are both existing devices on the market, and their related technologies are common knowledge in the field. Furthermore, this solution has clearly disclosed the connection method and usage steps of the two devices with the device, so they are not shown in the accompanying drawings.

[0032] The tensioning mechanism 7 includes a second preset groove 71, which is located on both sides of the middle section inside the processing box 1. A third motor 72 is installed above the interior of one of the second preset grooves 71, and the output end of the third motor 72 is connected to a transmission screw 73. A second screw sleeve 74 is screwed onto one side of the transmission screw 73, and a second guide frame 75 is fixed to the inner end of the second screw sleeve 74. A second guide rod 76 is fixed to the middle of the other second preset groove 71, and a tensioning mechanism is installed below the second guide frame 75. The tension roller 77 is connected to the second guide frame 75 and the second guide rod 76 to form a lifting guide connection. The operator can adjust the height of the tension roller 77 corresponding to the leather according to the tension of the leather. The specific adjustment method is as follows: the operator starts the third motor 72 to rotate the transmission screw 73. At this time, the second screw sleeve 74, which is threaded with the transmission screw 73, will drive the second guide frame 75 and the tension roller 77 set below it to move up and down in conjunction with the guiding action of the second guide rod 76, thereby achieving the purpose of adjusting the tension of the leather.

[0033] Working principle: When using this leather antibacterial and anti-mite treatment device to treat car seat leather, the operator can start the drive motor at one end of the take-up roller 4. At this time, the leather roll set on the unwind roller 3 will be sequentially wound up under the guidance of the two sets of guide rollers 5 and a tension roller 77. During this process, the operator can start the first motor 612 in advance to rotate the positive and negative lead screws 613. At this time, the pair of first lead screw sleeves 614 that are threaded with the positive and negative lead screws 613 will move closer to each other with their respective fixed first guide frames 615 and the guidance of the first guide rods 616. Thus, the leather rolls set on opposite sides of the pair of first guide frames 615 will move closer to each other. The brush rollers 619 have bristles that can precisely adhere to the upper and lower surfaces of the leather. At this time, the pair of brush rollers 619 can pre-brush the upper and lower surfaces of the leather under the drive of the second motors 618 at their respective ends. Relying on the physical friction of the bristles, they remove mites from the surface of the leather and the fiber layer, removing mite eggs and impurities hidden therein. At the same time, the industrial vacuum cleaner connected to the end of the main suction pipe 627 is started. The suction power generated by the vacuum cleaner can be transmitted to the corresponding section of the vacuum hood 623 through the connection of the three-way air pipe 626, a pair of telescopic hoses 625, the secondary suction pipe 624, and the vacuum holder 622. The suction end of the pair of vacuum hoods 623 is directly facing the pair of brush rollers 629. The brush roller 619 separates from the working leather section, allowing the suction to directly act on the removed mites and impurities, effectively improving the cleanliness of the leather. The leather then continues to be conveyed through the middle of a pair of spray nozzles 10. At this point, a liquid pump connected to one end of the liquid pipe 8 is activated, guiding the liquid containing the antibacterial solution from the tank (pool, box, etc.) to the distribution pipe 9 through the pipe connected to the other end of the pump. The liquid is then evenly sprayed from the spray nozzles on the pair of spray nozzles 10 opposite the working surface, further enhancing the antibacterial and mite-removing effect. Next, the heating wire inside the heating box 12 is activated to provide a heating source, and the fan 11 is activated to generate airflow that pulls on the heating source, spraying the outside of the heating box 12 and... Under the guiding dust filtering effect of the convection ventilation filter 13 set on one side of the processing box 1, the heat source can be evenly guided to the upper and lower surfaces of the leather after spraying, thereby improving the drying effect and preventing bacteria from growing after the leather is rolled up in a damp state. Secondly, the staff can adjust the height of the tension roller 77 corresponding to the leather according to the tension of the leather. The specific adjustment method is as follows: the staff starts the third motor 72 to rotate the transmission screw 73. At this time, the second screw sleeve 74, which is threaded with the transmission screw 73, will drive the second guide frame 75 and the tension roller 77 set below, and move up and down in conjunction with the guiding action of the second guide rod 76, thereby achieving the purpose of adjusting the tension of the leather.
