Description

Technical Field

[0001] This invention pertains to the field of rodless cylinders, specifically referring to an adjustable mechanical rodless cylinder for cleaning and dust removal. Background Technology

[0002] Rodless cylinders are playing an increasingly important role in industrial automation due to their simple structure, flexible operation, and wide range of applications. However, with technological advancements, the design of rodless cylinders has become increasingly sophisticated. While there are many types of existing rodless cylinders, pneumatic rodless cylinders are a superior choice due to their simple structure and convenient maintenance, making them a mainstream application in actual production.

[0003] However, most of the cleaning and dust removal technologies for pneumatic rodless cylinders on the market are external additional installations, which require additional cleaning after long-term use. Furthermore, the dust generated inside the cylinder due to wear and tear cannot be discharged, so effective improvements are urgently needed.

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

[0005] Prior art 2 (Chinese Invention Patent Announcement No. CN106837923B) discloses a rodless cylinder with a dust removal device, which is actually a magnetic couple rodless cylinder. An air blowing plate is added to the outside of the side cover, and multiple air blowing holes are set through the air blowing plate to remove dust when air is ventilated.

[0006] Existing technology 3 (Chinese Utility Model Patent Publication No. CN214617271U) discloses a rodless cylinder that can remove dust. It is actually a magnetic couple rodless cylinder. An air blowing plate is installed inside the side cover. Multiple air blowing holes are set through the air blowing plate. The air blowing plate optimizes the gas flow efficiency and allows air blowing to remove dust when air is ventilated.

[0007] However, this invention mainly targets pneumatic rodless cylinders. Based on previous development experience and feedback, it is known that the gas flow rate required for cleaning and dust removal is limited by the internal structure of the pneumatic rodless cylinder, resulting in limited dust removal effect. Therefore, the internal structure of the pneumatic rodless cylinder has been redesigned to effectively utilize the structure and passage to guide the airflow quickly, allowing the jet flow rate to achieve the purpose of dust removal more efficiently. In addition, it eliminates the need for additional dust collection boxes and allows for the adjustment of airflow strength according to needs, making it more flexible in use. Summary of the Invention

[0008] The main objective of this invention is to provide an adjustable rodless cylinder for cleaning and dust removal, comprising: a slide rail on the top of a rodless cylinder body for a slider to engage with a sealing strip; a rod-type actuating valve in a body channel located inside the rodless cylinder body below the slide rail; and a first end cap and a second end cap of the same structure on both sides of the rodless cylinder body.

[0009] The sealing strip is sandwiched between the slider and the rod-type actuating valve. The slider has a first exhaust passage and a first jet nozzle on each side, as well as a second exhaust passage and a second jet nozzle. The rod-type actuating valve has a first piston guide ring and a second piston guide ring, as well as a first air guide pipe and a second air guide pipe. When gas passes from the first end cap through the first air guide pipe, and then through the first piston guide ring to the first exhaust passage of the slider, it cooperates with the first jet nozzle to discharge the gas.

[0010] When the gas passes through the second end cap and the second air guide pipe, and then through the second piston guide ring to the second exhaust passage of the slider and cooperates with the second jet nozzle to discharge the gas, the rodless cylinder body can simultaneously remove internal and external dust during reciprocating operation.

[0011] Optionally, it also includes: a pair of throttling regulators, respectively disposed between the first exhaust passage and the first jet nozzle, and between the second exhaust passage and the second jet nozzle, for adjusting the flow rate of the gas discharged from the first jet nozzle and the second jet 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 rodless cylinder for cleaning and dust removal, comprising: a rodless cylinder body with a slide rail on its upper part for a slider to be fitted with a sealing strip; a rod-type direct-acting valve is also provided in a body channel located inside the rodless cylinder body below the slide rail; and a first end cap and a second end cap of the same structure are provided on both sides of the rodless cylinder body; the sealing strip is sandwiched between the slider and the rod-type direct-acting valve; and the slider has a first exhaust passage and a first air nozzle, and a second exhaust passage on each side. The rod-type direct-acting valve has a first side valve port and a second side valve port. The first side valve port is connected to the first exhaust passage, and the second side valve port is connected to the second exhaust passage. When gas passes through the first side valve port from the first end cover, it is discharged through the first exhaust passage of the slider in conjunction with the first air nozzle. When 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 conjunction with the second air nozzle, so that the rodless cylinder body can simultaneously remove internal and external dust during reciprocating operation.

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

[0014] This invention, by incorporating multiple exhaust passages and jet nozzles on the slider and integrating them with the air guide pipe within the rod-type actuated valve, enables the rodless cylinder to simultaneously clean both the internal and external surfaces during operation. In particular, the throttling regulator on the slider precisely controls the flow rate of the cleaning gas for optimal dust removal. This design not only improves the working efficiency of the rodless cylinder but also extends its service life, making it suitable for applications with high environmental cleanliness requirements, such as semiconductor manufacturing and precision instrument manufacturing. Compared to existing pneumatic rodless cylinders, it effectively increases the jet flow rate, making dust removal more efficient, and allows for adjustment of intensity according to needs, providing flexibility in production and use.

[0052] Generally, according to the preferred and feasible embodiments of the present invention, and in conjunction with the accompanying drawings Figures 1 to 2 To enhance understanding of the invention, a detailed description is provided below. The invention is an adjustable rodless cylinder for cleaning and dust removal, comprising: a rodless cylinder body 10, with a slide rail 20 on its upper part. The slide rail 20 is used for a slider 30 to be fitted with a sealing strip 31 to achieve waterproofing and dustproofing. Below the slide rail 20, a body channel 11 located inside the rodless cylinder body 10 is also provided with a rod-type actuating valve 40. The rodless cylinder body 10 is provided with a first end cap 50 and a second end cap 51 of the same structure on both sides.

[0053] Please see again Figures 3 to 4 The sealing strip 31 is sandwiched between the slider 30 and the rod-type actuating valve 40. The slider 30 has a first exhaust passage 301 and a first jet nozzle 303 on each side, and a second exhaust passage 302 and a second jet nozzle 304 on each side. The rod-type actuating valve 40 has 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 actuating valve 40 to guide gas 60 through the first air guide pipe 403 along the annular design to the first exhaust passage 301. Figure 3 The state is divided into three phases: a) initial state, b) moving state, and c) stopped state. The main determination is based on the direction of displacement of the slider 30 relative to the input of the first end cap 50 or the second end cap 51. Figure 3 Gas 60 is input from the first end cap 50 on the right side of the rodless cylinder body 10 to drive it. The arrow in the figure represents the displacement direction of the slider. Therefore, when gas 60 passes from the first end cap 50 through the first air guide pipe 403, and then through the first piston guide ring 401 to the first exhaust passage 301 of the slider 30, it is discharged from the first jet nozzle 303.

[0054] Please see again Figure 5Since the rodless cylinder of the present invention is divided into left and right blocks with the center as the center, its structure and operation are symmetrically designed. Therefore, the repeated parts of the structure will not be explained again. It can be seen that when the gas 60 passes from the second end cover 51 through the second air guide pipe 404, and then through the second piston guide ring 402 to the second exhaust passage 302 of the slider 30 and cooperates with the second jet nozzle 304 to discharge the gas 60, in summary, when the rodless cylinder body 10 reciprocates, it can simultaneously remove the dust inside and outside.

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

[0056] Another preferred embodiment of the present invention is shown in the accompanying drawings. Figures 6 to 15 The difference from the main embodiment is that the original rod-type actuating valve 40 has the first air guide tube 403 and the second air guide tube 404 inside. In this other embodiment, the original rod-type actuating valve 40 is replaced with a rod-type straight-through actuating valve 70 with a modified structure. The original rod-type actuating valve 40 does not have the configuration of two air guide tubes inside. This design allows the rod-type straight-through actuating valve 70 to be pushed when gas 60 is input from both end caps, thereby changing the subsequent path of gas 60. This can effectively reduce the input of gas 60 to achieve the purpose of energy saving. If there are explanations that are repeated in structure or have 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 rodless cylinder body 10, with a slide rail 20 on its upper part, the slide rail 20 being used for a slider 30 to be fitted with a sealing strip 31, a rod-type direct-acting valve 70 being provided in a body channel 11 located inside the rodless cylinder body 10 below the slide rail 20, and a first end cap 50 and a second end cap 51 of the same structure being provided on both sides of the rodless cylinder body 10.

[0058] The sealing strip 31 is sandwiched between the slider 30 and the rod-type direct-flow actuation valve 70. The slider 30 has a first exhaust passage 301 and a first jet nozzle 303, a second exhaust passage 302 and a second jet nozzle 304 on each side. The rod-type direct-flow actuation valve 70 has 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 gas 60 passes through the first side valve port 71 from the first end cap 50, and then exits through the first exhaust passage 301 of the slider 30 in conjunction with the first jet nozzle 303; when gas 60 passes through the second side valve port 72 from the second end cap 51, and then exits through the second exhaust passage 302 of the slider 30 in conjunction with the second jet nozzle 304, the rodless cylinder body 10 can simultaneously remove internal and external dust during reciprocating operation.

[0060] A pair of throttling regulators 305 are respectively disposed between the first exhaust passage 301 and the first jet nozzle 303, and between the second exhaust passage 302 and the second jet nozzle 304, for adjusting the flow rate of the gas 60 discharged from the first jet nozzle 303 and the second jet 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, this invention provides an adjustable rodless mechanical cylinder for cleaning and dust removal. Its ingenious design integrates the cleaning system into the cylinder's structure, effectively solving the problem of dust accumulation and performance degradation inherent in traditional rodless cylinders during operation. Furthermore, by incorporating multiple exhaust passages and nozzles on the slider, coupled with a rod-type actuated valve or a rod-type direct-flow actuated valve, the rodless cylinder can simultaneously clean both the internal and external surfaces with each reciprocating motion. When compressed air or other gases enter the system, they are guided to the exhaust passages on the slider and ejected from the nozzles, forming a strong airflow that blows away dust adhering to the exterior and interior of the rodless cylinder. In addition, the design of the throttling adjustment component further enhances the precision of the cleaning effect. Whether employing a rod-type actuated valve or a rod-type direct-flow actuated valve, this invention effectively cleans the rodless cylinder and reduces gas consumption. This self-cleaning rodless cylinder is particularly suitable for applications with stringent environmental cleanliness requirements and can effectively improve production efficiency and extend equipment lifespan.
