[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "rear", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the scope of protection of the present invention.

[0031] like Figure 1As shown, in some embodiments of the filter rod cutter cooling device provided by the utility model, the cooling device includes a conveying pipe 1, a cooling component 2 and a cooling body 3, the conveying pipe 1 is configured to convey a cooling medium, the cooling component 2 is configured to cool the cooling medium, the cooling body 3 is arranged downstream of the cooling component 2, and a conveying channel is provided inside the cooling body 3, the conveying channel is connected to the conveying pipe 1, and the outlet of the conveying channel faces the cutter 4 so that the cooling medium is sprayed toward the cutter 4.

[0032] In the above embodiment, the cooling medium can be cooled by the cooling component 2 to reduce the temperature of the cooling medium. The conveying channel in the cooling body 3 can spray the cooled cooling medium to the cutter 4 to cool the cutter 4, thereby preventing the temperature of the cutter 4 from being too high and causing part of the material in the filter rod to melt, affecting the quality of the cut end face of the filter rod, avoiding problems such as uneven cut end face of the filter rod, and effectively ensuring the normal progress of subsequent processes.

[0033] Furthermore, by lowering the temperature of the cutter 4 , it is also possible to prevent powder from adhering to the surface of the cutter due to the high temperature, which is beneficial to maintaining the cleanliness of the cutter 4 and ensuring the subsequent cutting effect of the cutter 4 .

[0034] In some embodiments, the cooling body 3 is configured to clean the surface of the cutter 4 .

[0035] In the above embodiment, the cooling body 3 is constructed to not only cool the cutter 4 to reduce the temperature of the cutter 4, but also clean the surface of the cutter 4, promptly rinse off the substances adhered to the surface of the cutter 4, keep the cutter 4 clean, and ensure the subsequent cutting effect.

[0036] In some embodiments, the cooling body 3 is provided with an open slot 31 , the outlet of the conveying channel is arranged on the slot wall of the open slot 31 , and the cutter 4 is inserted into the open slot 31 .

[0037] By providing the opening slot 31, the cutter 4 can be conveniently inserted into the opening slot 31 without affecting the rotation of the cutter 4. Moreover, an outlet is provided on the slot wall of the opening slot 31 so that the cooling medium can be sprayed onto the cutter 4 located in the opening slot 31, and the entire cutter 4 can be cooled by the rotation of the cutter 4.

[0038] like Figures 2 to 4 As shown, the cooling body 3 is in a square shape as a whole, and the opening slot 31 is in a U shape. The opening of the opening slot 31 faces the cutter 4, and a part of the cutter 4 is located in the opening slot 31.

[0039] The front and rear side walls of the opening slot 31 are connected so that the cutter 4 can rotate relative to the cooling body 3 to avoid the cooling body 3 restricting the rotation of the cutter 4.

[0040] like Figure 3 and Figure 4 As shown, in some embodiments, the conveying channel includes a first channel 32 and a second channel 33 and a third channel 34 respectively connected to the two ends of the first channel 32, the outlet of the second channel 33 is arranged at the first groove wall of the opening groove 31, the outlet of the third channel 34 is arranged at the second groove wall of the opening groove 31, and the first groove wall and the second groove wall are arranged opposite to each other.

[0041] The first channel 32 is connected between the second channel 33 and the third channel 34. The first channel 32 is connected to the delivery pipe 1. After the cooling medium delivered by the delivery pipe 1 enters the first channel 32, it flows to the second channel 33 and the third channel 34 respectively.

[0042] The outlets of the second channel 33 and the third channel 34 extend to the groove walls on both sides of the opening groove 31 respectively, so that the cooling medium flows out of the second channel 33 and the third channel 34 and sprays onto the cutter 4 located between the groove walls on both sides to cool the cutter 4.

[0043] By providing the second channel 33 and the third channel 34, both sides of the cutter 4 can be cooled simultaneously. Compared with the solution of cooling only one side, the cooling effect and cooling speed can be greatly improved, so that the cutter 4 can be cooled more quickly.

[0044] In some embodiments, the conveying direction of the second channel 33 is inclined relative to the end surface of the cutter 4 ; and / or the conveying direction of the third channel 34 is inclined relative to the end surface of the cutter 4 .

[0045] By setting the second channel 33 and the third channel 34 to be inclined relative to the end face of the cutter 4, the cooling medium can be sprayed toward the cutter 4 at an angle, which not only cools the cutter 4, but also helps to flush away the substances adhering to the surface of the cutter 4, thereby cleaning the cutter 4.

[0046] In some embodiments, the angle between the conveying direction of the second channel 33 and the end face of the cutter 4 is an acute angle; and / or the angle between the conveying direction of the third channel 34 and the end face of the cutter 4 is an acute angle.

[0047] The second channel 33 and the third channel 34 are both arranged such that the angle between the conveying direction and the end surface of the cutter 4 is an acute angle, so that a better cooling and flushing effect can be achieved.

[0048] In some embodiments, the cooling body 3 is arranged above the cutter 4, and the conveying direction of the second channel 33 is inclined downward relative to the end surface of the cutter 4. Such an arrangement can make the cooling medium have a downward tilting tendency, and even if the area of ​​the portion of the cutter 4 located in the opening groove 31 is small, the downward tilting tendency of the cooling medium can be utilized to enable the cooling medium to cover a larger range, increase the cooling area, and improve the cooling effect; of course, the downward tilting tendency is also conducive to enhancing the flushing effect, so that the adhesion material falls down.

[0049] like Figure 1 As shown, in some embodiments, the delivery pipe 1 includes a first delivery pipe 11 and a second delivery pipe 12, the outlet of the first delivery pipe 11 is connected to the inlet of the cooling component 2, the outlet of the cooling component 2 is connected to the inlet of the second delivery pipe 12, and the outlet of the second delivery pipe 12 is connected to the inlet 30 of the delivery channel.

[0050] By providing the first delivery pipe 11 and the second delivery pipe 12 , the cooling component 2 can be provided between the first delivery pipe 11 and the second delivery pipe 12 , so that the cooling medium is cooled in the cooling component 2 and then enters the cooling body 3 through the second delivery pipe 12 .

[0051] In some embodiments, the filter rod cutter cooling device further comprises a supply device connected to the inlet of the conveying pipe 1 , and the supply device is configured to provide compressed air.

[0052] In the above embodiment, compressed air is used as the cooling medium, which can prevent the cooling medium from contaminating the material of the filter rod, and can keep the filter rod clean and safe to the greatest extent, which is conducive to ensuring the quality of the filter rod.

[0053] In some embodiments, the cooling component 2 includes a vortex cooler. The vortex cooler can cool the cooling medium. After the compressed air enters the vortex tube, the flow rate inside the vortex tube is converted and cold air can be output, thereby achieving the purpose of reducing the temperature of the compressed air.

[0054] In some embodiments, the filter rod cutter cooling device further comprises a flow regulating valve 5 disposed on the delivery pipe 1 , and the flow regulating valve 5 is configured to adjust the delivery flow of the delivery pipe 1 .

[0055] By setting the flow regulating valve 5, the delivery flow of the delivery pipe 1 can be adjusted. For example, when the flow regulating valve 5 is adjusted to the minimum gear, the delivery flow of the delivery pipe 1 is zero, which is equivalent to closing the valve port of the flow regulating valve 5; when the flow regulating valve 5 is adjusted to the maximum gear, the delivery flow of the delivery pipe 1 is the maximum, which is equivalent to fully opening the valve port of the flow regulating valve 5, and the flow of the delivery pipe 1 reaches the maximum at this time; when the flow regulating valve 5 is adjusted to other gears, the delivery flow of the delivery pipe 1 can be set to a set size, which can be adjusted according to needs.

[0056] In other embodiments, if there is no need to adjust the flow rate, the flow regulating valve 5 can be replaced by a switch valve.

[0057] In some embodiments, the filter rod cutter cooling device also includes a control device and a driving device, the driving device is configured to drive the cutter 4 to rotate, the control device is connected to the flow regulating valve 5 and the driving device signal, and the control device is configured to make the flow regulating valve 5 and the driving device open or close synchronously.

[0058] By setting up a control device, the flow regulating valve 5 and the driving device can be opened or closed synchronously, so that the cooling body 3 and the cutter 4 can work synchronously, which can effectively control the utilization rate of the cooling medium and reduce waste.

[0059] The following is combined with Figures 1 to 4 , the structure and working process of an embodiment of the filter rod cutter cooling device of the utility model are described:

[0060] like Figure 1 As shown, the filter rod cutter cooling device includes a conveying pipe 1, a cooling component 2, a cooling body 3 and a flow regulating valve 5.

[0061] The flow regulating valve 5 is arranged on the first delivery pipe 11, the outlet of the first delivery pipe 11 is connected to the inlet of the cooling component 2, and the outlet of the cooling component 2 is connected to the delivery channel in the cooling body 3 through the second delivery pipe 12. Part of the cutter 4 is inserted into the opening groove 31 on the cooling body 3.

[0062] like Figure 2 As shown, the cutter 4 is in the shape of a disc, the cooling body 3 is in the shape of a square, an inlet 30 is provided on the side of the cooling body 3, and the outlet of the second delivery pipe 12 is connected to the inlet 30 to deliver the cooling medium to the delivery channel in the cooling body 3.

[0063] In other embodiments, the inlet 30 may also be disposed on other side surfaces of the cooling body 3 , such as on the top surface.

[0064] The opening groove 31 of the cooling body 3 opens downward, the groove bottom is upward, and both sides of the opening groove 31 are connected. The cutter 4 is inserted into the opening groove 31 from bottom to top.

[0065] like Figure 3 and Figure 4 As shown, the delivery channel in the cooling body 3 includes a first channel 32 , a second channel 33 and a third channel 34 .

[0066] The first channel 32 is located above the bottom surface of the opening groove 31, and the second channel 33 and the third channel 34 are respectively located inside the groove walls on both sides of the opening groove 31. The outlets of the second channel 33 and the third channel 34 are respectively located on the groove walls on both sides of the opening groove 31.

[0067] The first channel 32 is arranged horizontally, and the conveying direction of the first channel 32 is parallel to the central axis of the cutter 4. The angle between the conveying direction of the second channel 33 and the conveying direction of the first channel 32 is approximately 60°, and the angle between the conveying direction of the third channel 34 and the conveying direction of the first channel 32 is approximately 60°.

[0068] The working process of the filter rod cutter cooling device embodiment provided by the utility model is as follows:

[0069] When it is necessary to start the cutting operation, the control device controls the flow regulating valve 5 and the driving device for driving the cutter 4 to open synchronously, and the compressed air supplied by the supply device is delivered to the cooling component 2 through the first delivery pipe 11. The cooling component 2 undergoes energy conversion inside and delivers a cooling medium with a lower temperature, which is then delivered to the delivery channel of the cooling body 3 through the second delivery pipe 12; the cooling medium first enters the first channel 32, and then enters the second channel 33 and the third channel 34 respectively, and finally sprays out from the outlets of the second channel 33 and the third channel 34, spraying to both sides of the cutter 4, cooling both sides of the cutter 4 at the same time, and the cutter 4 can also be rinsed at the same time.

[0070] The embodiment of the utility model adopts the method of generating cold air through a vortex cooler with compressed air to reduce the temperature of the cutter during cutting, thereby ensuring the cutting quality of the filter rod; at the same time, the high-pressure gas of the compressed air is used to clean the cutting surface of the cutter, thereby ensuring that the cutter is in a good cutting state.

[0071] Based on the above filter rod cutter cooling device, the utility model further proposes a filter rod cutting device, which includes a cutter 4 and the above filter rod cutter cooling device.

[0072] The positive technical effects of the filter rod cutter cooling device in the above-mentioned embodiments are also applicable to the filter rod cutting device, which will not be described in detail here.

[0073] The filter rod cutting device provided by the utility model can be applied to a winding device to cut a longer filter rod into a plurality of shorter filter rods.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that without departing from the principle of the utility model, the specific implementation method of the utility model can still be modified or some technical features can be replaced by equivalents, and these modifications and equivalent replacements should be included in the scope of the technical solution for protection of the utility model.
