Description

Technical Field

[0001] This invention relates to the technical field of latex cylinder structures, and more particularly to a latex cylinder for a filter rod forming machine. Background Technology

[0002] The KDF4 forming machine's centerline glue cylinder is used to store latex. During filter rod production, latex is sprayed onto the center of the inner surface of the forming paper via a glue pump, glue hose, and glue gun. This ensures that the wound filaments adhere tightly to the forming paper, preventing separation of the filter nozzle filaments from the forming paper during suction. Latex easily oxidizes and solidifies in air. Solidified latex adheres to the inner wall of the glue cylinder and is difficult to clean. Furthermore, each time latex is replenished, the upper layer of oxidized and solidified latex in the cylinder must be removed; otherwise, it can easily lead to glue supply system malfunctions, resulting in glue interruptions or uneven glue levels, ultimately producing substandard filter rods. In addition, oxidized and solidified latex cannot be recycled, causing resource waste. Existing latex glue cylinders are open, with a box at the bottom and a lid at the top. The cylinder lid is not sealed; glue is added from the top after removing the lid. In open latex tanks, the latex is in direct contact with the air, which makes it prone to oxidation and solidification into dry glue. Dry glue can easily clog the glue supply system, leading to problems such as system malfunctions and uneven glue application. Therefore, each time latex is replenished, the solidified latex must be removed, and the glue tank and glue supply system must be cleaned once a week. The dry glue formed by oxidation and solidification cannot be recycled, resulting in resource waste. Summary of the Invention

[0003] This invention provides a latex cylinder for a filter rod forming machine, which solves the problem that the latex in the existing latex cylinder is prone to oxidation and solidification, and blockage of the glue supply system. It can prevent the latex in the latex cylinder from solidifying into dry glue, reduce resource waste, and improve the efficiency of glue supply.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A latex cylinder for a filter rod forming machine includes: a cylinder body, a cylinder cover, a piston, and a latex supply ball valve;

[0006] The glue cylinder body has a cylindrical structure, a glue supply pipe is provided at the bottom of the glue cylinder body, a glue supply ball valve is provided on the glue supply pipe, and a cylinder cover is provided at the top of the glue cylinder body;

An exhaust pipe passes through the piston and extends to the outside of the glue cylinder cover and is provided with a removable sealing cap.

[0008] The side of the glue cylinder body is fitted with a self-locking quick-connector. The external glue injection tube injects glue into the glue cylinder body through the glue injection self-locking quick-connector, so that the latex in the glue cylinder body squeezes the gas in the cylinder body to be discharged out of the cylinder, and pushes the piston upward to the set position.

[0009] Preferably, it also includes: a counterweight;

[0021] This invention provides a latex cylinder for a filter rod forming machine. A piston is slidably mounted inside the cylinder. A glue supply pipe is located at the bottom of the cylinder, and a self-locking quick-connect glue injection connector is located on the side. An external glue injection pipe injects glue into the cylinder through the self-locking quick-connect glue injection connector. This causes the latex inside the cylinder to compress the gas inside the cylinder and expel it, pushing the piston upward to a set position. This invention solves the problem of latex in existing latex cylinders easily oxidizing and solidifying, clogging the glue supply system. It prevents the latex in the cylinder from solidifying into dry glue, reducing resource waste and improving glue supply efficiency. Attached Figure Description

[0027] To enable those skilled in the art to better understand the embodiments of the present invention, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and implementation methods.

[0028] To address the problem of latex in current latex tanks easily oxidizing and solidifying in the air, resulting in resource waste, this invention provides a latex tank for a filter rod forming machine. This solution addresses the issue of latex in existing latex tanks easily oxidizing and solidifying, clogging the glue supply system. It prevents the latex in the tank from solidifying into dry glue, reducing resource waste and improving glue supply efficiency.

[0029] like Figure 1 and Figure 2 As shown, a latex cylinder for a filter rod forming machine includes: a cylinder body 2, a cylinder cover 4, a piston 6, and a latex supply ball valve 1;

[0030] The glue cylinder body 2 is cylindrical. A glue supply pipe is located at the bottom of the glue cylinder body 2, and a glue supply ball valve 1 is installed on the glue supply pipe. A cylinder cover 4 is located at the top of the glue cylinder body 2. A piston 6 is slidably disposed inside the glue cylinder body 2. The piston 6 has a circular structure and is perpendicular to the inner wall of the glue cylinder body 2. An exhaust pipe extends through the piston 6, reaching outside the glue cylinder cover 4 and is fitted with a removable sealing cap. A glue-filling self-locking quick-connect 7 is located on the side of the glue cylinder body 2. An external glue injection pipe injects glue into the glue cylinder body through the glue-filling self-locking quick-connect 7, causing the latex inside the glue cylinder body to compress the gas inside the cylinder body to be expelled outside, and pushing the piston 6 upward to a set position.

[0031] In practical applications, such as Figures 1-4As shown, the glue supply ball valve 1 is connected to the bottom of the glue cylinder body. A vent hole 61 is installed on the piston 6, and a vent pipe is installed on the vent hole 61. When not venting, the vent pipe is sealed with a sealing cap. A glue-adding self-locking quick-connect is installed on the side of the bottom edge of the glue cylinder. The glue supply ball valve 1 is connected to the glue supply pump. The opening and closing of the ball valve is controlled by the extended valve stem 8. When the glue cylinder needs to be removed, the ball valve is closed. During normal production, the glue supply ball valve is opened by the extended valve stem 8, and the glue flows into the glue supply pump, where it is applied to the forming paper. When adding glue, the glue supply ball valve is closed by controlling the extended valve stem 8, and the external pump pumps the glue from the glue bucket into the glue cylinder body 2. When adding latex, the external glue pump injects latex into the glue cylinder through the glue-adding self-locking quick-connect 7. The piston inside the cylinder pressurizes the latex liquid, squeezing and expelling the air inside the cylinder. This reduces the oxidation reaction between the latex liquid and the air, slows down the latex oxidation rate, reduces resource waste caused by oxidation and solidification, and minimizes the need for frequent cleaning of the latex cylinder. It solves the problem of latex in existing latex cylinders easily oxidizing and solidifying, clogging the glue supply system. It also prevents the latex in the latex cylinder from solidifying into dry glue, reducing resource waste and improving the efficiency of glue supply.

[0032] The latex cylinder also includes a counterweight 5; the counterweight 5 is disposed on the upper top surface of the piston 6 and is used to counterweight the piston 6 so that the piston can compress the latex in the cylinder with a set weight.

[0033] In practical applications, different counterweights exert varying degrees of pressure on the latex within the cylinder. Larger counterweights result in greater gas discharge pressure and higher glue supply pressure. Counterweight 5 moves upward along with piston 6. When the amount of glue in the cylinder decreases, the piston moves downward along with the amount of glue due to the gravity of counterweight 5.

[0034] Furthermore, the counterweight is equipped with a handle so that the operator can move the counterweight by using the handle.

[0035] like Figure 4 As shown, the piston 6 is provided with an annular groove, and an O-ring 62 is provided in the annular groove. This is used to seal the cylinder body of the glue cylinder with the piston and the O-ring, isolating the latex in the glue cylinder from the air. During use, when the amount of glue in the glue cylinder decreases, the piston, under the gravity of the counterweight, forces the gas out of the cylinder or moves downwards along with the amount of glue.

[0036] Furthermore, limit blocks are symmetrically arranged on the inner wall of the cylinder to limit the upward position of the piston.

[0037] In practical applications, two 180°-arranged limit blocks are designed on the inner side of the top of the glue cylinder to prevent the counterweight and piston from being pushed out of the glue cylinder.

[0038] like Figure 3 As shown, the outer side wall of the rubber cylinder cover 4 is symmetrically provided with side ears 42.

[0039] Furthermore, the inner bottom surface of the glue cylinder cover 4 is provided with a rib 41. A rib is designed on the inner side of the glue cylinder cover to prevent the glue cylinder cover and glue cylinder seal from being difficult to open. Two side ears arranged at 180° are designed on the outer side of the cover for opening the glue cylinder cover.

[0040] The glue cylinder is equipped with a liquid level detection sensor (not shown in the figure) for real-time detection of the glue liquid level.

[0041] In practical applications, photoelectric sensors can be used for liquid level detection, such as... Figure 1 As shown, the photoelectric sensor is mounted on the cylinder cover, and wire 3 enters through a hole in the cylinder cover and connects to the photoelectric sensor. Of course, other types of level gauges can also be used for the liquid level detection sensor.

[0042] The latex tank also includes a controller (not shown in the figure); the controller is connected to the liquid level detection sensor, and the controller reports an alarm when the latex liquid level is less than a set threshold.

[0043] The latex tank also includes a display screen; the display screen is connected to the controller via a signal and is used to display the latex liquid level in real time.

[0044] As can be seen, the present invention provides a latex cylinder for a filter rod forming machine. A piston is slidably arranged inside the cylinder. A glue supply pipe is provided at the bottom of the cylinder, and a glue-adding self-locking quick connector is provided on the side. An external glue injection pipe injects glue into the cylinder through the glue-adding self-locking quick connector, causing the latex inside the cylinder to compress the gas inside the cylinder and expel it out, thus pushing the piston upward to a set position. This solves the problem of latex in existing latex cylinders easily oxidizing and solidifying, clogging the glue supply system. It can prevent the latex in the latex cylinder from solidifying into dry glue, reduce resource waste, and improve the efficiency of glue supply.

The above description is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the figures. Any changes made in accordance with the concept of the present invention, or equivalent embodiments modified to have equivalent changes, shall be within the protection scope of the present invention as long as they do not exceed the spirit covered by the specification and figures.
