Description

Technical Field

[0001] The utility model relates to the field of rodless cylinders, and in particular to a rodless cylinder that is energy-saving and clean. Background Art

[0002] Compared with other types, rodless cylinder is a relatively new type of cylinder. The existing structure is mainly composed of piston and cylinder, while rodless cylinder is composed of slide rail and slider. Because of this, rodless cylinder has the advantages of small size, light weight, high precision and long life, and has been widely used in recent years.

[0003] The aforementioned rodless cylinders are roughly divided into magnetic rodless cylinders, hydraulic rodless cylinders, and pneumatic rodless cylinders; magnetic rodless cylinders usually have a simple structure and are easy to manufacture, but have a small driving force and low precision, and are only suitable for occasions where precision requirements are not high. Hydraulic rodless cylinders have a large driving force and high precision, but a relatively complex structure and high maintenance costs. Pneumatic rodless cylinders have a simple structure and are easy to maintain, but have a small driving force and high energy consumption, and pneumatic rodless cylinders are more commonly used on the market. The improvements of this utility model focus on a simpler structure, which is relatively easy to manufacture and maintain, as well as being able to effectively remove dust and reduce energy consumption. Utility Model Content

[0004] The main purpose of the utility model is to provide a rodless cylinder with energy saving and cleaning, which includes: a rodless cylinder body mainly composed of a slide rail and a slider, the two sides of the slide rail are provided with end covers of the same structure, the slider is arranged above the slide rail, and the slide rail has a body channel inside for the pair of end covers to communicate with each other;

[0005] A dust scraping mechanism is arranged on both sides of the slider, and a zipper sealing structure is arranged between the slide rail and the slider to provide waterproof and dustproof purposes, and a zipper sealing channel is formed between the zipper sealing structures, and a first channel and a second channel are arranged inside the end cover. When the airflow passes through a quick exhaust valve arranged in the first channel and is connected to a vacuum valve in the second channel, the main body channel is connected to a vacuum channel, and the vacuum valve cooperates with the second channel and the vacuum channel to generate a vacuum state so that the dust in the zipper sealing channel is discharged through the vacuum channel through a discharge hole of the vacuum valve.

[0006] Optionally, the zipper sealing structure is mainly composed of an upper sealing strip and a lower sealing strip clamped on the slide rail, and further cooperates with an upper guide block and a lower guide block of the slider. The upper guide block is arranged on the outside of the upper sealing strip, and the lower guide block is arranged between the upper sealing strip and the lower sealing strip. The slider is moved to push open and close, so that the zipper sealing structure has airtightness.

[0007] Optionally, at least one steel cable is disposed inside each of the upper sealing strip and the lower sealing strip to enhance the tensile strength.

[0008] Optionally, a barrier is provided inside the slider, which is roughly in the shape of a double lip to block splashing liquid and a large amount of falling dust.

[0009] Optionally, the dust scraping mechanism further includes: a scraping member, which is locked and cooperated with both sides of the slider, and an elastic member is provided between the scraping member and the slider to make the scraping member fit tightly with the zipper sealing structure.

[0010] Optionally, it also includes: a protective frame, which is arranged below the slider and cooperates with the zipper sealing structure to make the stability of the slider displacement more stable.

[0011] The utility model uses the original internal space of the end cover to establish multiple channels to cooperate with the installation of the vacuum generator and the quick exhaust valve, and is further assisted by the setting of the zipper sealing structure, so as to ensure that the slide rail is waterproof and dustproof. When the air is normally inlet and outlet, the dust can be sucked out in a vacuum manner by the vacuum generator and then discharged and collected together. Compared with the previous existing technology, there is no need to construct a relatively complex collection structure that is difficult to ensure the leakage of dust, and it also has a waterproof design. The above are the improved advantages of the utility model. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Generally, according to the best feasible embodiment of the utility model, and in conjunction with the accompanying drawings Figures 1 to 5 After the detailed description, the understanding of the utility model is increased. The utility model is a rodless cylinder with energy-saving and cleaning functions, which includes: a rodless cylinder body 10, which is composed of a slide rail 20 and a slider 30, a pair of end covers 40 of the same structure are arranged on both sides of the slide rail 20, the slider 30 is arranged above the slide rail 20, and a blocking member 303 is also arranged inside the slider 30, which is roughly in the shape of a double lip to block splashing liquid and a large amount of falling dust, and the slide rail 20 has a body channel 11 inside for connecting the pair of end covers 40, a dust scraping mechanism 31 is arranged on both sides of the slider 30, and a zipper sealing structure 32 is arranged between the slide rail 20 and the slider 30, and a zipper sealing channel 323 is formed between the zipper sealing structures 32;

[0042] The aforementioned dust scraping mechanism 31 is also provided with a scraping member 313 that is locked and cooperated on both sides of the slider 30, and an elastic member 312 is provided between the scraping member 313 and the slider 30 to enable the scraping member 313 to fit tightly with the zipper sealing structure 32, and a protective frame 311 is also provided under the slider 30, and the protective frame 311 can cooperate with the zipper sealing structure 32 for greater stability.

[0043] The aforementioned zipper sealing structure 32 is mainly composed of an upper sealing strip 321 and a lower sealing strip 322 which are clamped on the slide rail 20, and further cooperate with an upper guide block 301 and a lower guide block 302 of the slider 30. The upper guide block 301 is arranged on the outside of the upper sealing strip 321, and the lower guide block 301 is arranged between the upper sealing strip 321 and the lower sealing strip 322. The slider 30 is displaced to push open and close, so that the zipper sealing structure 32 has airtightness. The interior of the upper sealing strip 321 and the lower sealing strip 322 are each provided with at least one steel cable 3211 to enhance the tensile strength. Two steel cables are used in the present invention, but the number is not limited to this.

[0044] like Figure 4 As shown, first of all, Figure 4 From top to bottom, they are (a) standby state, (b) start-up state, and (c) pressure-maintaining state. The standby state is initially unused. When the airflow starts to push the slider 30, the slider 30 moves from left to right. This is the (b) start-up state. After the airflow continues to push the slider 30 to the right end cover 40, it is the (c) pressure-maintaining state. From the start-up state to the pressure-maintaining state, it can be seen that the relevant vacuum valves 42 are all in the start-up state, and the exhaust volume is limited at the vacuum nozzle of the vacuum valve 42 to produce a deceleration effect.

[0045] Please see again Figure 5 A first channel 41 and a second channel 42 are provided inside the end cover 40. When the airflow passes through a quick exhaust valve 411 provided in the first channel 41 and is connected to a vacuum valve 421 in the second channel 42, the main body channel 11 is connected to a vacuum channel 43. The vacuum valve 421 cooperates with the second channel 42 and the vacuum channel 43 to generate a vacuum state so that the dust in the zipper sealing channel 323 is discharged through the vacuum channel 43 through a discharge hole 4211 of the vacuum valve 421, thereby achieving the purpose of cleaning.

[0046] In summary, the utility model is a rodless cylinder with energy-saving and cleaning functions. The passage in the end cover can be used to cooperate with the installation of the quick exhaust valve 411 and the vacuum valve 421. When the slider 30 is pushed and displaced by the airflow, the dust can be absorbed by the vacuum action and discharged outside the rodless cylinder for collection. In addition, the zipper sealing structure 32 and the dust scraping mechanism 31 can enhance the dust collection and waterproofing effects, so that the rodless cylinder can save energy and achieve the purpose of cleaning at the same time.
