Description

Technical Field

[0001] The utility model belongs to the technical field of pneumatic equipment, in particular to a dustproof protection device for a cylinder. Background Art

[0002] Existing filling machines easily generate dust around the machine during the canning process or before the bag is dropped and sealed, especially when canning sugar powder. These sugar powders are easy to adhere to the surface of the machine. Due to long-term use, sugars will continue to accumulate or melt and adhere to the surface of components, especially when attached to the repeatedly extended and retracted cylinder piston rod. As the piston rod retracts and retracts, dust will be brought into the cylinder, causing damage to the seal and air leakage in the cylinder itself, which will lead to damage to the cylinder, causing equipment shutdown and production suspension, greatly affecting the equipment life and increasing equipment maintenance costs.

[0005] Furthermore, the sleeve is a cylindrical structure with a through cavity in the middle, and the sleeve includes a fixing portion and an annular groove portion located at the upper end of the fixing portion and integrally formed with the fixing portion, and a plurality of threaded holes are evenly arranged on the side of the fixing portion, and the threaded holes are connected to the through cavity, and the annular groove portion is matched with the telescopic rubber sleeve, and one end of the telescopic rubber sleeve is sleeved on the annular groove portion.

[0006] Furthermore, the number of the threaded holes is 4 or more.

[0007] Furthermore, an air nozzle joint is installed on the vent hole, and the air nozzle joint is connected to the muffler through an air pipe.

[0008] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0009] 1. The utility model sets the telescopic rubber sleeve on the telescopic rod of the cylinder and fixes it through the shaft sleeve and the pipe clamp, so that the telescopic rod of the cylinder is completely in the telescopic rubber sleeve, providing a clean and closed space for the telescopic rod of the cylinder and prolonging the service life of the cylinder;

[0010] 2. In the cylinder dust protection device of the utility model, a vent hole is provided on the shaft sleeve, and the vent hole is connected with the inside of the telescopic rubber sleeve. When the cylinder performs telescopic action, it can effectively avoid the generation of vacuum in the rubber telescopic sleeve, which causes excessive resistance of the cylinder telescopic rod and affects the stable operation of the cylinder.

[0016] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0017] like Figure 1-Figure 4 As shown, the cylinder dust protection device includes a cylinder body 1, a sleeve 2 fixedly mounted on the front cylinder cover of the cylinder body 1, and a telescopic rubber sleeve 3 mounted on the telescopic rod of the cylinder body 1, one end of the telescopic rubber sleeve 3 is fixedly connected to the sleeve 2, and the other end of the telescopic rubber sleeve 3 is fixedly arranged at the front end of the telescopic rod through a pipe clamp 4, and a vent hole 5 is arranged on the side wall of the sleeve 2, and the vent hole 5 is connected with the interior of the telescopic rubber sleeve 3.

[0018] Specifically, by sleeve-mounting the telescopic rubber sleeve 3 onto the telescopic rod of the cylinder body 1 and fixing it by the shaft sleeve 2 and the pipe clamp 4, the telescopic rod of the cylinder is completely in the telescopic rubber sleeve 3, providing a clean and enclosed space for the telescopic rod of the cylinder, effectively preventing external sugar dust and the like from adhering to the telescopic rod, and improving the service life of the cylinder; in addition, by arranging an air vent 5 on the shaft sleeve 2 and making the air vent 5 communicate with the inside of the telescopic rubber sleeve 3, during the operation of the cylinder, the telescopic rod of the cylinder extends, driving the telescopic rubber sleeve 3 to extend, and in this process, air is sucked in through the air vent 5 to avoid the generation of a vacuum inside the telescopic rubber sleeve 3, resulting in excessive resistance of the telescopic rod of the cylinder, thereby affecting the stable operation of the cylinder; when the telescopic rod of the cylinder contracts, the telescopic rubber sleeve 3 is recovered at the same time, and the air is exhausted outwardly through the air vent 5 at this time.

[0019] Furthermore, an air nozzle joint 10 is installed on the air vent 5, and the air nozzle joint 10 is connected to the muffler 12 through an air pipe 11. Specifically, the air pipe 11 is extended to a dust-free area and is equipped with a muffler 12, which can effectively block external dust or air impurities from entering the air vent, thereby providing good protection for the cylinder and extending the service life of the cylinder.

[0020] Furthermore, the shaft sleeve 2 is a cylindrical structure with a through cavity 6 in the middle. The shaft sleeve 2 includes a fixing portion 7 and an annular groove portion 8 located at the upper end of the fixing portion 7 and integrally formed with the fixing portion 7. A plurality of threaded holes 9 are evenly arranged on the side of the fixing portion 7. The threaded holes 9 are connected to the through cavity 6. The annular groove portion 8 is matched with the telescopic rubber sleeve 3, and one end of the telescopic rubber sleeve 3 is sleeved on the annular groove portion 8.

[0021] Specifically, the installation process of the cylinder dust protection device is as follows: first, the through cavity 6 of the sleeve 2 is sleeved on the front cylinder head, and the bolts are screwed into the threaded holes 9 and connected with the front cylinder head, wherein the number of evenly arranged threaded holes 9 is more than 4, which can make the connection between the sleeve 2 and the front cylinder head more stable, and then the telescopic rubber sleeve 3 is sleeved on the telescopic rod, and one end of the telescopic rubber sleeve 3 is sleeved into the annular groove portion 8, and the other end is fixed to the front end of the telescopic rod through the pipe clamp 4, and the air nozzle joint 10 is installed at the vent hole 5, which is extended to the dust-free area by connecting the air pipe 11, and the muffler 12 is installed at the tail of the air pipe 11; the utility model fixes the sleeve 2 to the front cylinder head by bolts, and fixes the telescopic rubber sleeve 3 by the pipe clamp 4 and the annular groove portion 8, and the installation structure is simple, which achieves the purpose of facilitating the installation and replacement of wearing parts.

[0022] The dustproof protection device for the cylinder of the utility model can effectively ensure the cleanliness of the telescopic rod of the cylinder and prevent the adhesion of sugar powder by the telescopic rubber sleeve 3 which is telescopic along with the telescopic rod of the cylinder. At the same time, combined with the vent hole 5, the movement of the cylinder will not be affected, so that it can run stably, prolonging the service life of the cylinder and ensuring continuous and stable canning production tasks.
