[0026] like Figure 1 , Figure 2and Figure 3 As shown, the embodiment of the present application provides a locking end cap of a rubber roller. The rubber roller may be a rubber control roller or a rubber application roller as described in the background technology section. For example, the rubber roller may be a rubber control roller of a rubber application device of a YJ216 filter tip adapter. Figure 3 The inside of the rubber roller 7 forms a cooling channel along its axial direction for the cooling medium to pass through. In the present application, the cooling medium can be a gas, such as air, or other fluids such as liquid. The flow direction of the cooling medium can be Figure 3 As shown by the arrow in , when the cooling medium flows through the rubber roller 7, the rubber roller 7 can be cooled, thereby further reducing the temperature of the glue on the rubber roller 7, thereby ensuring the performance of the glue. The outlet of the cooling channel is formed by an end head with a through hole, an outer thread is provided on the outer periphery of the end head, and a bearing 8 is provided on one side of the end head adjacent to the middle of the rubber roller 7 to facilitate the rotation of the rubber roller 7. In this embodiment, the end head can be the end of the mounting shaft of the rubber roller 7.

[0027] See also Figure 1 and Figure 2 The locking end cap comprises a locking end cap body 1 and a cover body 4. A screw hole is provided in the middle of the locking end cap body 1. The locking end cap body 1 can realize threaded matching with the end head through the screw hole and the external thread to limit the movement of the bearing 8 along the axial direction of the end head; the cover body 4 is arranged on the top surface of the locking end cap body 1 away from the rubber roller 7, and a gap is formed between the cover body 4 and the top surface. When the locking end cap is installed on the rubber roller 7, the gap is connected with the cooling channel, so that the cooling medium flowing out of the cooling channel can flow out to the outside through the gap. In this embodiment, the cover body 4 can be made of stainless steel, and the cover body 4 can be installed on the locking end cap body 1 in a variety of ways, such as screw connection, welding, riveting, etc. The cooling medium flowing out of the cooling channel changes its flow direction after encountering the cover body 4 and flows out to the outside environment along the gap. The cover body 4 can disperse the gas in the cooling channel and protect the cooling channel at the same time. The gap formed between the cover body 4 and the top surface can be determined according to the flow rate of the discharged fluid, and the gap can ensure the gas flowability inside the rubber roller 7. In some embodiments, the locking end cap body 1 may be cylindrical, the cover body 4 may be circular, and the cover body 4 is mounted on the locking end cap body 1. A 360° gap may be formed between the locking end cap body 1 and the cover body 4, so that cooling media such as air can flow out of the gap 360° into the atmosphere and effectively take away heat, thereby improving the cooling effect and achieving the purpose of cooling the rubber roller 7. The thickness of the cylindrical locking end cap body 1 may be about 3 mm longer than the threaded section of the end head, so that the airflow in the rubber roller 7 can flow out smoothly.

[0028] When the locking end cover provided in the embodiment of the present application is installed on the end head of the rubber roller 7, the locking end cover body 1 can limit the axial movement of the bearing 8 of the rubber roller 7 to axially lock the rubber roller 7. At the same time, a gap for the cooling medium to pass through is formed between the cover body 4 and the locking end cover body 1 to facilitate the discharge of the cooling medium of the rubber roller 7.

[0029] In some embodiments, the top surface forms a recessed portion capable of accommodating the cover body 4, and the size of the side wall of the recessed portion gradually decreases inwardly along the axial direction of the locking end cap body 1, so that the side wall of the recessed portion forms a trumpet shape. In this embodiment, this arrangement allows the cover body 4 to be embedded in the locking end cap body 1, making the structure of the locking end cap more compact; at the same time, the side wall of the recessed portion forms a trumpet shape, which can facilitate the oblique outflow of the fluid. Preferably, the side wall of the recessed portion can be a 45° chamfered slope.

[0030] In some embodiments, the cover body 4 is truncated, and the inclination of the side of the cover body 4 corresponds to the inclination of the side wall of the recess, for example, both are chamfered at 45°, and the side of the cover body 4 is spaced apart from the side wall of the recess. In this embodiment, this arrangement can make the cover body 4 and the locking end cover body 1 more compatible, and at the same time, the side of the cover body 4 is parallel to the side wall of the recess, forming a uniform flow channel, making the outflow direction of the cooling medium easier to control. Exemplarily, the interval between the side of the cover body 4 and the side wall of the recess can be 3 mm to facilitate the discharge of gas.

[0031] In some embodiments, the locking end cap further includes a plurality of first spacers 3, which are arranged between the cover body 4 and the top surface to form a gap, and the plurality of first spacers 3 are distributed along the circumference of the screw hole. In this embodiment, the first spacers 3 are arranged to maintain a gap between the cover body 4 and the top surface, and the size of the gap is determined by the thickness of the first spacers 3. At the same time, the plurality of first spacers 3 are distributed along the circumference of the screw hole, so that the spacers can support the cover body 4 more stably.

[0032] In some embodiments, a first through hole is provided on the first spacer 3, a second through hole corresponding to the number of the first spacer 3 is provided on the cover body 4, a first mounting hole is provided at a position on the top surface corresponding to the second through hole, and an internal thread is provided in the first mounting hole; the locking end cover also includes a first screw 5 corresponding to the number of the second through holes, the first screw 5 passes through the second through hole and the first through hole in sequence and is threadedly engaged with the first mounting hole. In this embodiment, the first screw 5 can simultaneously fix the cover body 4 and the first spacer 3, further ensuring the working stability of the locking end cover. Preferably, the first screw 5 can be a countersunk screw, which can be immersed in the cover body 4, making the locking end cover structure more compact.

[0033] In some embodiments, the locking end cap also includes a plurality of second spacers 2, the second spacers 2 are arranged between the cover body 4 and the top surface, the thickness of the second spacer 2 is the same as that of the first spacer 3, and the plurality of second spacers 2 are distributed along the circumference of the screw hole, and the second spacers 2 and the first spacers 3 are alternately distributed along the circumference of the screw hole; a mounting shaft is provided on the second spacer 2, and a second mounting hole is also provided on the top surface, and the mounting shaft is provided in the second mounting hole. The second mounting hole can be a pin hole without threads. In this embodiment, by providing the second spacer 2, the stability of the gap size is further ensured, the first spacer 3 and the second spacer 2 can improve the airflow dispersion effect of the rubber roller 7, and at the same time, the second spacer 2 can be directly inserted into the second mounting hole for installation, which is convenient for the assembly and disassembly of the locking end cap. The depth of the second mounting hole can be determined based on the length of the mounting shaft of the second spacer 2. For example, the depth of the second mounting hole can be approximately 2 mm greater than the length of the mounting shaft. In some embodiments, such as Figure 2 As shown, the number of the first spacers 3 and the second spacers 2 can be two each. In this case, the two first spacers 3 are positioned by the first screws 5, and the two second spacers 2 are positioned by the mounting shafts. This arrangement ensures that the cover body 4 is stably fixed while ensuring the stability of the gap size with as few spacers as possible.

[0034] In some embodiments, the locking end cap body 1 is provided with a notch, and the notch extends from the screw hole along the radial direction of the locking end cap body 1 to the outer periphery of the locking end cap body 1, so that the locking end cap body 1 is in a "C" shape; the side of the locking end cap body 1 is also provided with a locking hole, the locking hole is communicated with the notch and the extension direction is perpendicular to the extension direction of the section of the notch, and the section of the notch without the locking hole is also provided with a third mounting hole with an internal thread, and the third mounting hole is aligned with the locking hole, and the locking end cap also includes a second screw 6, and the second screw 6 passes through the locking hole and the third mounting hole in sequence to achieve the locking of the locking end cap body 1 on the end head. In this embodiment, through this setting, when tightening the second screw 6, the locking end cap can be more reliably connected to the rubber roller 7. Exemplarily, the second screw 6 can be a hexagon socket screw, and the size of the notch can be 2mm.

[0035] like Figure 4 As shown, in some embodiments, a circular boss is provided on the bottom surface of the locking end cover body 1 close to the rubber roller 7, concentrically with the screw hole, and the circular boss protrudes from the bottom surface. The height of the circular boss can be 2 mm. By providing a circular boss on the side of the locking end cover body 1 close to the rubber roller 7, better axial positioning of the bearing 8 can be achieved. In some embodiments, the bearing 8 can be provided on a bearing seat, and the circular boss can axially position the bearing 8 and the bearing seat.

[0036] In some embodiments, the direction of the thread in the screw hole is set so that when the rubber roller 7 works normally, the rubber roller 7 drives the end head to generate a movement trend of screwing into the screw hole. In this embodiment, this setting method can prevent the locking end cap from loosening when the rubber roller 7 rotates normally, thereby realizing a self-locking function. For example, for the YJ216 filter tip installation machine, the thread in the thread can be a left-handed thread.

[0037] In some embodiments, the side of the locking end cap body 1 is provided with an anti-slip structure to facilitate the screwing in and out of the locking end cap. The anti-slip structure can be formed by knurling.

[0038] The locking end cap provided in the embodiment of the present application has a simple structure, is easy to install and disassemble, has few parts, and is highly practical. In the cigarette equipment of tobacco enterprises, especially for the rubber roller of the YJ216 filter tip assembling machine, it not only has a locking function but also has an exhaust function, effectively solving the problem of the flow direction of the internal hot air flow after the rubber roller has been running for a long time, and at the same time enhancing the cooling effect of the rubber roller, which is convenient for maintenance.

[0039] Based on the above-mentioned embodiments of the present application, in the absence of explicit negation or conflict, the technical features of one embodiment may be beneficially combined with one or more other embodiments.

[0040] Although some specific embodiments of the present application have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are only for illustration and not for limiting the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified or some technical features may be replaced by equivalents without departing from the scope and spirit of the present application.
