Description

Technical Field

[0001] The utility model relates to the field of rodless cylinders, in particular to an adjustable cleaning and dust removal mechanical rodless cylinder. Background Art

[0002] Rodless cylinders are playing an increasingly important role in industrial automation, owing to their simple structure, flexible motion, and widespread application. However, with technological advancements, rodless cylinder design has also become increasingly sophisticated. While there are many types of rodless cylinders available, pneumatic rodless cylinders are a preferred choice due to their simple structure and ease of maintenance, making them a more mainstream option in actual production applications.

[0003] However, most of the structural application technologies for cleaning and dust removal of pneumatic rodless cylinders on the market are external additional installations, which require additional cleaning after long-term use. In addition, the dust generated by wear and tear inside the cylinder body cannot be discharged, so effective improvement is urgently needed.

[0004] Prior art 1 (China Invention Patent Publication No. CN108825586A) discloses a dustproof rodless cylinder, which is mainly a mechanical rodless cylinder with a through pipe set at the front end of the internal piston, further sucking dust from the non-moving piston end and then connecting it to an external dust removal box through the through pipe.

[0005] Prior art 2 (Chinese invention patent publication number CN106837923B) discloses a rodless cylinder with a dust removal device, which is actually a magnetic rodless cylinder. A blowing plate is installed on the outside of the side cover, and multiple blowing holes are set through the blowing plate, which can perform air blowing and dust removal during ventilation.

[0006] Prior art 3 (China Utility Model Patent Publication No. CN214617271U) discloses a rodless cylinder capable of removing dust, which is actually a magnetic rodless cylinder. A blowing plate is installed inside the side cover, and multiple blowing holes are set through the blowing plate. The blowing plate optimizes the gas circulation efficiency, allowing air blowing and dust removal during ventilation.

[0007] However, the present invention is mainly aimed at pneumatic rodless cylinders. Compared with previous development experience and feedback, it is known that the gas flow required for cleaning and dust removal will be limited by the internal structure of the pneumatic rodless cylinder, which in turn leads to limited dust removal effect. Therefore, the internal structure of the pneumatic rodless cylinder is redesigned, which can effectively utilize the structure and passages to quickly guide the airflow, so that the jet flow can be more efficient for the purpose of dust removal. There is no need to collect it through the additional installation of related dust removal boxes, and the strength of the airflow can be adjusted according to needs, making it more flexible in use. Utility Model Content

[0008] The main purpose of the utility model is to provide an adjustable cleaning and dust removal mechanical rodless cylinder, which includes: a slide rail is provided on the upper part of a rodless cylinder body, the slide rail is used for a slider to be sleeved with a sealing strip, a body channel located inside the rodless cylinder body below the slide rail is also provided with a rod-type actuating valve, and a first end cover and a second end cover of the same structure are provided on both sides of the rodless cylinder body;

[0009] The lower portion of the sealing strip is sandwiched between the slider and the rod-type actuated valve. A first exhaust passage and a first air nozzle, as well as a second exhaust passage and a second air nozzle, are respectively provided on both sides of the slider. A first piston guide ring, a second piston guide ring, and a first air duct and a second air duct are provided within the rod-type actuated valve. When gas passes from the first end cap through the first air duct, then through the first piston guide ring to the first exhaust passage of the slider, the gas is discharged in conjunction with the first air nozzle.

[0010] When the gas passes through the second air duct from the second end cover and then through the second piston guide ring to the second exhaust passage of the slider, the gas is discharged in conjunction with the second air nozzle, so that the rodless cylinder body can simultaneously remove internal and external dust during reciprocating operation.

[0011] Optionally, it also includes: a pair of throttling adjustment members, which are respectively arranged between the first exhaust passage and the first nozzle, and between the second exhaust passage and the second nozzle, for adjusting the flow rate of the gas discharged from the first nozzle and the second nozzle, so that the gas can be guided to be discharged below the slider.

[0012] Another object of the present invention is to provide an adjustable cleaning and dust removal mechanical rodless cylinder, which includes: a rodless cylinder body with a slide rail on the top, the slide rail is used for a slider to be sleeved with a sealing strip, a body channel located below the slide rail inside the rodless cylinder body is also provided with a rod-type straight-through actuating valve, and a first end cover and a second end cover of the same structure are provided on both sides of the rodless cylinder body; the lower part of the sealing strip is clamped between the slider and the rod-type straight-through actuating valve, and the slider is provided with a first exhaust passage and a first air nozzle, as well as a second exhaust passage on both sides.

When the gas passes through the second side valve port from the second end cover, it is discharged through the second exhaust passage of the slider in cooperation with the second air nozzle. This allows the rodless cylinder body to simultaneously remove internal and external dust during reciprocating operation.

[0013] Optionally, it also includes: a pair of throttling adjustment members, which are respectively arranged between the first exhaust passage and the first nozzle, and between the second exhaust passage and the second nozzle, for adjusting the flow rate of the gas discharged from the first nozzle and the second nozzle, so that the gas can be guided to be discharged below the slider.

[0014] The utility model provides multiple exhaust passages and air nozzles on the slider, and matches it with the air guide tube inside the rod-type actuator valve, so that the rodless cylinder can clean the inside and outside synchronously during operation. In particular, the throttling adjustment part on the slider can accurately control the flow of the cleaning gas to achieve the best dust removal effect. This design not only improves the working efficiency of the rodless cylinder, but also extends its service life.

[0052] Generally, according to the best feasible embodiment of the present invention, and in conjunction with the accompanying drawings Figures 1 to 2 After a detailed explanation, in order to increase the understanding of the utility model, the utility model is an adjustable cleaning and dust removal mechanical rodless cylinder, which includes: a rodless cylinder body 10, with a slide rail 20 on the top, the slide rail 20 is used for a slider 30 to be sleeved with a sealing strip 31 to achieve the purpose of waterproofing and dustproofing, and a body channel 11 located inside the rodless cylinder body 10 below the slide rail 20 is also provided with a rod-type actuating valve 40, and a first end cover 50 and a second end cover 51 of the same structure are provided on both sides of the rodless cylinder body 10.

[0053] See also Figures 3 and 4 The lower portion of the sealing strip 31 is sandwiched between the slider 30 and the rod-type actuated valve 40. The slider 30 is provided with a first exhaust passage 301 and a first air nozzle 303, as well as a second exhaust passage 302 and a second air nozzle 304 on both sides. The rod-type actuated valve 40 is provided with a first piston guide ring 401 and a second piston guide ring 402, as well as a first air guide pipe 403 and a second air guide pipe 404. The first piston guide ring 401 allows the rod-type actuated valve 40 to transfer the gas 60 along the annular path to the first exhaust passage 301 via the first air guide pipe 403. Figure 3 The state is divided into a initial state, b moving state, and c stop state. The main judgment is based on the displacement direction of the slider 30 and the input of the first end cover 50 or the second end cover 51. Figure 3 The rodless cylinder body 10 is driven by inputting gas 60 from the first end cover 50 on the right side, and the direction of the arrow in the figure represents the displacement direction of the slider. Therefore, when a gas 60 passes through the first air duct 403 from the first end cover 50, then through the first piston guide ring 401 to the first exhaust passage 301 of the slider 30 to cooperate with the first air nozzle 303 to discharge the gas 60.

[0054] See also Figure 5Since the rodless cylinder of the present invention is divided into left and right blocks by the center, its structure and operation are designed to be symmetrical with each other, so the repeated parts of the structure are not explained in detail. It can be seen that when the gas 60 passes through the second air duct 404 from the second end cover 51, and then through the second piston guide ring 402 to the second exhaust passage 302 of the slider 30, the gas 60 is discharged in conjunction with the second air nozzle 304. Therefore, in summary, when the rodless cylinder body 10 is in reciprocating operation, it can simultaneously remove internal and external dust.

[0055] In addition, there is a pair of throttling adjustment members 305, which are respectively arranged between the first exhaust passage 301 and the first air nozzle 303, and between the second exhaust passage 302 and the second air nozzle 304, for adjusting the flow rate of the gas 60 discharged from the first air nozzle 303 and the second air nozzle 304, so that the gas 60 can be guided to be discharged below the slider 30, and the flow rate can be concentrated.

[0056] Another preferred embodiment of the present invention is shown in the accompanying drawings. Figures 6 to 15 , which is different from the main embodiment in that the original rod-type actuating valve 40 has the first air duct 403 and the second air duct 404 inside, while this other embodiment replaces the original rod-type actuating valve 40 with a structurally modified rod-type straight-through actuating valve 70, which does not have the two air ducts inside. This design allows the gas 60 to be input from both side end covers and push the rod-type straight-through actuating valve 70 to change the subsequent path of the gas 60, thereby effectively reducing the input of the gas 60 to achieve energy saving. In the following description, if there are explanations of the repeated structure or the same principle as the main embodiment, they will not be repeated one by one. Please refer to the explanation in the main embodiment.

[0057] Therefore, another embodiment of the present invention includes a structure comprising: a rodless cylinder body 10 having a slide rail 20 on the top thereof, the slide rail 20 being used for a slider 30 to be sleeved with a sealing strip 31, a body channel 11 located inside the rodless cylinder body 10 below the slide rail 20 is also provided with a rod-type direct-acting valve 70, and a first end cover 50 and a second end cover 51 of the same structure are provided on both sides of the rodless cylinder body 10.

[0058] The lower part of the sealing strip 31 is sandwiched between the slider 30 and the rod-type direct-acting valve 70. The slider 30 is provided with a first exhaust passage 301 and a first air nozzle 303, and a second exhaust passage 302 and a second air nozzle 304 on both sides. The rod-type direct-acting valve 70 is provided with a first side valve port 71 and a second side valve port 72. The first side valve port 71 is connected to the first exhaust passage 301, and the second side valve port 72 is connected to the second exhaust passage 302.

[0059] When a gas 60 passes through the first side valve port 71 from the first end cover 50, the gas 60 is then discharged through the first exhaust passage 301 of the slider 30 in cooperation with the first air nozzle 303; when the gas 60 passes through the second side valve port 72 from the second end cover 51, the gas 60 is then discharged through the second exhaust passage 302 of the slider 30 in cooperation with the second air nozzle 304, so that the rodless cylinder body 10 can simultaneously remove internal and external dust during reciprocating operation.

[0060] A pair of throttling adjustment members 305 are respectively arranged between the first exhaust passage 301 and the first air nozzle 303, and between the second exhaust passage 302 and the second air nozzle 304, for adjusting the flow rate of the gas 60 discharged from the first air nozzle 303 and the second air nozzle 304, so that the gas 60 can be guided to be discharged below the slider 30 and the flow rate can be concentrated.

[0061] In summary, the present invention provides an adjustable cleaning and dust removal mechanical rodless cylinder. Its design cleverly integrates a cleaning system into the rodless cylinder's structure, effectively solving the problem of traditional rodless cylinders easily accumulating dust and affecting performance during operation. Furthermore, by providing multiple exhaust passages and air nozzles on the slider, and using a rod-type actuating valve or a rod-type straight-through actuating valve, the rodless cylinder can simultaneously clean both the interior and exterior during each reciprocating motion. Therefore, when compressed air or other gases enter the system, they are directed to the exhaust passages on the slider and ejected from the air nozzles, forming a strong airflow that blows away dust adhering to the exterior and interior of the rodless cylinder. Furthermore, the design of the throttling adjustment element further enhances the precision of the cleaning effect. Whether using a rod-type actuating valve or a rod-type straight-through actuating valve, the present invention can effectively clean the rodless cylinder and reduce gas consumption. This self-cleaning rodless cylinder is particularly suitable for applications with strict environmental cleanliness requirements, and can effectively improve production efficiency and extend equipment life.
