[0025] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but only represents selected embodiments of the present invention.

[0026] First embodiment

[0027] like Figures 1 to 8As shown, the present invention discloses a roller cleaning mechanism, comprising a frame 100 and a roller 6 and a knife roller 7 pivotally connected to the frame 100, and the roller 6 and the knife roller 7 can both rotate around their own axes, and the roller 6 and the knife roller 7 have opposite rotation directions. The roller 6 is located above the knife roller 7, and a facial mask cutter is integrally formed on the surface of the knife roller 7 facing upward. The roller 6 fits the knife roller 7, and the facial mask roll passes through the fitting surface of the roller 6 and the knife roller 7 to achieve cutting of the facial mask. A cleaning device 8 is also provided on the frame 100, and the cleaning device 8 is used to clean the roller 6. Therefore, the cleaning device 8 is provided to achieve real-time cleaning of the roller 6, thereby improving the cleaning effect, the yield rate of the finished product, and the processing efficiency, and eliminating the potential safety hazards of the staff in the process of cleaning the roller 6.

[0028] Further, such as Figure 3 As shown, the cleaning device 8 is provided with at least one scraper 20, one end of which abuts against the surface of the pressure roller 6 for cleaning the pressure roller 6; by arranging at least one scraper 20 on the surface of the pressure roller 6, the surface of the pressure roller 6 can be cleaned.

[0029] like Figure 3 As shown, in order to improve the cleaning effect, prevent impurities from being stuck between the scraper 20 and the pressure roller 6, and prevent the facial mask from sticking to the surface of the pressure roller 6, the scraper 20 is inclined relative to the vertical plane, and the cleaning device 8 is provided with a blowing device 24, and the blowing device 24 acts on the upper end surface of the scraper 20; thus, by providing the blowing device 24, and the blowing device 24 acts on the upper end surface of the scraper 20, the cleaning effect on the pressure roller 6 is improved.

[0030] like Figure 2 and Figure 3 As shown, the cleaning device 8 includes a second mounting frame 2 and a driving device 3, the second mounting frame 2 is pivoted on the frame 100, the driving device 3 is fixedly mounted on the frame 100 by bolts, the driving device 3 is used to drive the second mounting frame 2 to rotate, and the scraper 20 is arranged on the second mounting frame 2; the second mounting frame 2 includes a connecting shaft 43 and a mounting portion 21, the connecting shaft 43 is pivoted on the frame 100 and can rotate around its own axis, and the mounting portion 21 is fixedly mounted on the connecting shaft 43; thus, the connecting shaft 43 is driven to rotate by the driving device 3, and then the scraper 20 is abutted against the pressure roller 6, thereby realizing the installation and operation of the cleaning device 8.

[0031] To further improve the cleaning effect, Figure 3 and Figure 5As shown, the scraper 20 includes a first scraper 22 and a second scraper 23, the first scraper 22 is inclined relative to the vertical plane and is located above the second scraper 23, and the first scraper 22 does not contact the second scraper 23, there is a certain angle between the first scraper 22 and the second scraper 23, and the extension line of the end of the first scraper 22 close to the pressure roller 6 intersects with the upper end surface of the second scraper 23; the blowing device 24 includes an air duct opened on the mounting portion 21 and a blowing generating device connected to the air inlet of the air duct, the blowing generating device can be a blower or a suction fan, and a blower is preferably used in this embodiment, and the air duct is used to blow air to the first scraper 22 to remove impurities located on the first scraper 22, the second scraper 23 and the surface of the pressure roller 6; thereby, the wind acting on the first scraper 22 by the blowing device 24 can be directly blown on the side of the second scraper 23 close to the pressure roller 6, so that impurities can be cleaned in time.

[0032] like Figures 4 to 8 As shown, the mounting portion 21 includes a mounting plate, an air outlet plate 214 and an air inlet plate 215, the first scraper 22 and the second scraper 23 are both mounted on the mounting plate, the mounting plate includes a first mounting plate 212 and a second mounting plate 213, the first scraper 22 and the second scraper 23 are respectively located above and below the first mounting plate 212, the air outlet plate 214 is mounted on the upper end surface of the first scraper 22, the air inlet plate 215 is mounted on the upper end surface of the air outlet plate 214, the air duct is arranged on the air inlet plate 215 and the air outlet plate 214, the air outlet plate 214 is provided with a plurality of air outlet slots 243 on the side away from the pressure roller 6, and the air inlet plate 215 is provided with an air outlet slot 244. The air duct 245 and the air inlet 244 connected to the air duct 245, one end of the air duct 245 is connected to the outside through the air inlet 244, and the other end extends to the upper end surface of the air outlet plate 214, one end of the air outlet slot 243 is connected to the air duct 245, and the other end is connected to the outside, so as to blow air toward the upper end surface of the first scraper 22, the air duct 245 of the air inlet plate 215 and the air outlet slot 243 of the air outlet plate 214 jointly form an air duct; thus, by jointly providing an air duct on the air inlet plate 215 and the air outlet plate 214, the wind generated by the blowing generating device is blown along the air duct toward the first scraper 22 and the second scraper 23 arranged below the first scraper 22.

[0033] Furthermore, the mounting portion 21 also includes a mounting base 211 arranged at the bottom thereof, and the first scraper 22 and the second scraper 23 are both mounted on the mounting base 211 through a mounting plate. Considering that the wind generated by the blowing device will be blown out in a fan shape through the wind slot 243, part of the wind will flow out from both sides of the mounting base 211 before being blown to the pressure roller 6, which will lead to an increase in energy consumption of the blowing device. At the same time, part of the dust will be blown to both sides of the mounting base 211 with the wind, making the surrounding area full of dust. Therefore, it is considered to install wind shields on both sides of the mounting base 211, and the wind shields are used to prevent the wind generated by the blowing device from overflowing to both sides of the mounting base 211 through the wind slot 243, while increasing the blowing acting on the pressure roller 6, thereby improving the blowing effect and reducing energy consumption.

[0034] Furthermore, the mounting base 211 and the windshield plates installed on both sides of the mounting base 211 together form a garbage collection box with an opening toward the pressure roller 6, and the garbage collection box is used to collect dust and debris on the first scraper 22 and the second scraper 23; thus, by providing a garbage collection box at the bottom of the mounting portion 21, the environmental sanitation around the equipment is improved.

[0035] Taking into account that the distance between the scraper 20 and the roller 6 cannot be accurately controlled during the actual working process, if the distance between the scraper 20 and the pressure roller 6 is too close, the scraper 20 will be crushed and damaged; if the distance is too far, the scraper 20 will not be able to abut the pressure roller 6 and cannot achieve the purpose of cleaning the roller 6. In order to control the relative distance between the scraper 20 and the pressure roller 6, a limiting device 5 is also provided on the connecting shaft 43. The limiting device 5 is used to limit the rotation angle of the connecting shaft 43 and thereby limit the second mounting frame 2. Specifically, the limiting device 5 is a turntable 51. A plurality of positioning holes are opened on the turntable 51. When the turntable 51 rotates to the target position, a positioning pin of a suitable length is inserted into the positioning hole so that the positioning pin abuts the mounting frame 100, thereby limiting the second mounting frame 2.

[0036] As a preference, the limiting device 5 may also have other implementations, such as Figure 2 As shown, the limiting device 5 includes at least one turntable 51 welded or installed on the connecting shaft 43 by screws, and a protrusion 52 is integrally formed on the turntable 51. When the turntable 51 rotates a certain angle, the protrusion 52 can abut the frame 100 to limit the rotation of the connecting shaft 43, thereby achieving the limitation of the second mounting frame 2.

[0037] like Figure 2As shown, the latter technical solution is preferred in this embodiment, whereby the connection shaft 43 is limited by setting a limit device 5, thereby controlling the distance between the scraper 20 and the pressure roller 6, thereby improving the cleaning effect and service life of the scraper 20.

[0038] In order to facilitate the adjustment of the position between the cleaning device 8 and the frame 100, a first mounting frame 1 is further provided on the cleaning device 8, and a plurality of mounting positions 11 are provided on the first mounting frame 1. The position between the cleaning device 8 and the frame 100 can be adjusted by installing different mounting positions 11 on the frame 100.

[0039] In order to improve the cleaning effect of the pressure roller 6, as Figure 3 As shown, a cleaning sponge 25 is also installed on the mounting portion 21 , and the cleaning sponge 25 is used to clean the surface of the pressure roller 6 ; thus, by installing the cleaning sponge 25 on the mounting portion 21 , the cleaning effect on the pressure roller 6 is improved.

[0040] The driving device 3 can be a motor or a cylinder, and the connecting shaft 43 is installed at the power output end of the motor to drive the connecting shaft 43. Figure 1 As shown, this embodiment is driven by a cylinder, and a swing arm 42 is welded or bolted to one end of the connecting shaft 43, and the swing arm 42 is pivotally connected to the power output end of the cylinder, thereby realizing the cylinder driving the connecting shaft 43.

[0041] During operation, the cylinder is started, and the cylinder drives the connecting shaft 43 to rotate. The protrusion 52 on the connecting shaft 43 abuts against the frame 100, and the connecting shaft 43 stops rotating. At this time, the first scraper 22 and the second scraper 23 are both in contact with the surface of the pressure roller 6, and the knife roller 6 is cleaned in real time. The blower is turned on, and the blowing device 24 blows air to the first scraper 22 to remove impurities on the surface of the first scraper 22, the second scraper 23 and the pressure roller 6.

[0042] Second embodiment

[0043] Based on the first embodiment, the difference of this embodiment is that: a third scraper is also installed on the mounting portion 21, and one end of the third scraper abuts against the surface of the pressure roller 6 for cleaning the surface of the pressure roller. Specifically, the third scraper is installed on the mounting plate and is located between the first scraper 22 and the second scraper 23, and the first scraper 22, the third scraper, and the second scraper 23 all abut against the lower half of the pressure roller 6. At this time, the distances between the first scraper 22, the third scraper, and the second scraper 23 and the vertical plane where the central axis of the pressure roller 6 is located are reduced in sequence. The first scraper 22 is small, and the first scraper 22 intersects with the upper end face of the third scraper along the extension line close to the pressure roller 6, and the third scraper intersects with the upper end face of the second scraper along the extension line close to the pressure roller 6. The air generated by the blower of the blowing device 24 enters through the air inlet 244, passes through the air flow channel 245, and is blown from the air outlet slot 243 to the first scraper 22, the third scraper, and the second scraper 23 in sequence; therefore, by adding the third scraper, the blowing device 24 can blow air to the first scraper 22, the third scraper, and the second scraper 23 to remove impurities, thereby improving the cleaning effect of the cleaning device 8.

[0044] Third embodiment

[0045] Based on the first embodiment, the difference of this embodiment lies in: considering that the blowing device blows from the side of the first scraper 22 away from the pressure roller 6 to the side close to the pressure roller 6, the second scraper 23 is located below the first scraper 22, and the wind can only blow to the side of the second scraper 23 close to the pressure roller 6, and the debris on other parts of the second scraper 23 cannot be removed by blowing. Therefore, it is considered to open a second air duct on the mounting plate, and the air outlet of the second air duct faces the upper end surface of the second scraper 23, thereby, the blowing can cover the upper end surface of the second scraper 23, thereby improving the cleaning effect of the second scraper 23.

[0046] Fourth embodiment

[0047] Based on the first embodiment, the difference of this embodiment lies in that: no wind shield plates are installed on both sides of the mounting base 211, and the coverage of the blowing air can be controlled by changing the position and opening angle of the air outlet slots 243 on the air outlet plate 214 to prevent the blowing air from overflowing from both sides of the mounting base 211 and causing environmental pollution. Specifically, the air outlet plate 214 is provided with a plurality of air outlet slots 243 on the side away from the pressure roller 6, and the opening angle of the air outlet slots 243 and the opening position on the air outlet plate 214 are changed to prevent the blowing air from overflowing from both sides of the air outlet plate 214, thereby reducing the dust content in the air around the equipment, improving the production environment, simplifying the equipment and saving production materials.

[0048] The above description is only a preferred embodiment of the present invention, and the present invention is not limited to the above embodiment. As long as the technical solutions for achieving the purpose of the present invention by basically the same means are achieved, they all fall within the protection scope of the present invention.
