Description

Technical Field

[0001] This utility model relates to a cleaning device for cigarette equipment, and more particularly to a cleaning device for paper feed rollers. Background Technology

[0002] The cigarette paper feeding and printing system mainly consists of a feeding device, a first feeding roller, a second feeding roller, and a printing system. Cigarette paper is output from the feeding device and, guided by the first feeding roller, passes sequentially through a paper belt tension control device, the first stamping roller of the first printing device, and the second stamping roller of the second printing device. The first and second stamping rollers of the first and second printing devices respectively print the trademark on the cigarette paper. After printing the trademark, the cigarette paper passes through a stamping adjustment device and enters the second feeding roller, finally passing through a paper feeder into the YJ116 type rolling mill. The purpose of the cigarette paper feeding and printing system is to provide pre-printed cigarette paper for the rolling mill and to enable non-stop paper replacement.

[0003] However, when the cigarette paper enters the second feed roller after the trademark is printed, the trademark-printed surface of the cigarette paper is in contact with the working surface of the second feed roller, and a pre-tightening force is applied by a pressure roller on the back of the cigarette paper. As a result, a small amount of incompletely solidified trademark printing ink will stick to the surface of the second feed roller. After a long period of operation, more and more dried ink blocks will accumulate on the surface of the feed roller, causing unstable cigarette paper feeding and cigarette paper surface contamination. Utility Model Content

[0004] This utility model provides a paper feed roller cleaning device that can automatically clean the ink on the paper feed roller, keep the surface of the paper feed roller clean, and ensure stable and clean delivery of cigarette paper, thereby solving the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above problems is: to provide a paper feed roller cleaning device, including a mounting base, a mounting rod, and a cleaning component. The mounting base is fixedly installed, one end of the mounting rod is inserted into the mounting base, the mounting rod is arranged parallel to the paper feed roller, and the cleaning component is fixedly installed on the mounting rod. The cleaning component has an abutment contact portion that seamlessly fits the uneven side surface of the paper feed roller.

[0006] Furthermore, the abutting contact portion includes multiple first cleaning brush surfaces that contact the concave paper feeding roller surface of the paper feeding roller for conveying cigarette paper, and multiple second cleaning brush surfaces that contact the raised separating roller surfaces between adjacent concave paper feeding roller surfaces of the paper feeding roller for conveying cigarette paper, with a second cleaning brush surface correspondingly provided between any two adjacent first cleaning brush surfaces.

[0007] Furthermore, the cleaning component is configured as a cleaning brush, which is inclinedly disposed above the paper feed roller, and the lower end of the cleaning component is in contact with the side surface of the paper feed roller.

[0008] Furthermore, the contact portion is configured as the lower end portion of the body of the cleaning component.

[0009] Furthermore, the cleaning component is configured as a sheet with a thickness of 1.5 mm made of polytetrafluoroethylene.

[0010] Furthermore, the cleaning component has a cleaning installation through hole, and the mounting rod has a radially threaded installation hole and a mounting bolt; the mounting bolt passes through the cleaning installation through hole to connect with the threaded installation hole, thereby fixing the cleaning component to the mounting rod.

[0011] Furthermore, the cleaning installation through hole is a strip-shaped through hole.

[0012] Furthermore, the mounting rod has an axially formed mounting surface, and the cleaning mounting through hole is located at the mounting surface.

[0013] Furthermore, the mounting base is provided with an adjustable clamping mounting hole and a clamping thread structure. The adjustable clamping mounting hole is used for inserting one end of the mounting rod into the mounting base. The clamping thread structure can be adjusted to fix one end of the mounting rod to the mounting base by adjusting the size of the adjustable clamping mounting hole.

[0014] Furthermore, the adjustable clamping mounting hole includes a clamping mounting shaft hole and an adjustable gap radially disposed relative to the clamping mounting shaft hole. The lower end of the adjustable gap communicates with the clamping mounting shaft hole, and the upper end extends to the surface of the mounting base. The clamping thread structure includes a threaded connection hole disposed on one side of the adjustable gap and opened on the mounting base, a clamping adjustment through hole disposed on the other side of the adjustable gap and extending through the mounting base, and a clamping bolt that passes through the clamping adjustment through hole to engage with the threaded connection hole.

[0015] The beneficial effects of this utility model are: This utility model discloses a paper feed roller cleaning device. Technicians can install a cleaning component onto a mounting rod. The cleaning component extends along the axial direction of the paper feed roller, with its lower end seamlessly contacting the circumferential surface of the roller. When the paper feed roller rotates to transport cigarette paper, the cleaning component continuously scrapes the circumferential surface of the roller to clean residual ink, preventing printing ink from remaining on the roller surface during cigarette paper transport. This ensures the surface structure of the roller, stabilizes cigarette paper transport, and prevents the cigarette paper surface from being contaminated by residual ink on the roller.

[0016] In addition, the tilt angle of the cleaning component and the distance from its lower end to the mounting rod can be adjusted so that the cleaning device of this utility model can be applied to paper feed rollers of different sizes and models, with high adaptability and strong practicality.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The following will be based on Figures 1 to 5 The present invention will now be described in more detail.

[0023] Please see Figure 1 and Figure 2 ,by Figure 1 Taking the orientation shown as an example, a paper feed roller cleaning device of a specific embodiment of this utility model includes a mounting base 11, a mounting rod 12, and a cleaning component 13. In this embodiment, the mounting base 11 is also used for the through-hole insertion of the drive shaft of the paper feed roller 14. The mounting base 11 is located on the right rear side. The paper feed roller 14 and the mounting rod 12 are both fixed on the mounting base 11 and are both facing the left front side. The paper feed roller 14 and the mounting rod 12 are parallel vertically. The cleaning component 13 is a sheet-like object. The upper end of the cleaning component 13 is fixed to the mounting rod 12 by a threaded structure, and the lower end of the cleaning component 13 abuts against the circumferential side surface of the paper feed roller 14.

[0024] Furthermore, given that the circumferential surface of the paper feed roller 14 is not flat, it is alternately provided with raised dividing roller surfaces 142 and concave paper feed roller surfaces 141 in the axial direction. The concave paper feed roller surfaces 141 are used to contact and transport cigarette paper, while the raised dividing roller surfaces 142 are used to maintain an appropriate distance between adjacent concave paper feed roller surfaces 141 to avoid mutual contact and interference between adjacent cigarette paper being transported. In this embodiment, the lower end of the cleaning member 13 also has a contact portion that can simultaneously maintain seamless contact with all raised dividing roller surfaces 142 and all concave paper feed roller surfaces 141 on the circumferential surface of the paper feed roller 14.

[0025] When the paper feed roller 14 is driven to rotate to move the cigarette paper, the cleaning member 13 can scrape the circumferential surface of the paper feed roller 14 through its lower end contact portion to prevent printing ink residue from remaining on the paper feed roller 14.

[0026] Further, please refer to Figure 1 , Figure 2 ,by Figure 1 Taking the orientation shown as an example, in this embodiment, the lower end of the cleaning component 13 is also provided with multiple first cleaning surfaces 131 and multiple second cleaning surfaces 132 corresponding to the paper feed roller 14. The height positions of the first cleaning surfaces 131 and the second cleaning surfaces 132 are also different. The multiple first cleaning surfaces 131 and the multiple second cleaning surfaces 132 are also arranged alternately along the axial direction of the paper feed roller 14. These first cleaning surfaces 131 and second cleaning surfaces 132 are connected to form an abutting contact portion, so as to ensure that when the cleaning component 13 is arranged to extend along the axial direction of the paper feed roller 14, the cleaning component 13 can maintain full and seamless contact with the paper feed roller 14 through the abutting contact portion, so as to ensure that the cleaning component 13 can fully clean the side surface of the paper feed roller 14 without any omissions.

[0027] Here it needs to be explained that, Figure 1 Taking the orientation shown as an example, in this embodiment, neither the first cleaning surface 131 nor the second cleaning surface 132 is a single plane. Both the first cleaning surface 131 and the second cleaning surface 132 include the lower end face of the cleaning component 13 and the side slope on the left side of the lower end of the cleaning component 13. In this way, the contact part can ensure full and seamless contact with the circumferential side surface of the paper feeding roller 14.

[0028] Furthermore, in this embodiment, when the paper feed roller 14 is running, the cleaning component 13 remains in contact with the paper feed roller 14. As a result, the cleaning component 13 will generate heat due to continuous friction with the circumferential surface of the paper feed roller 14. In order to prevent the cleaning component 13 from melting and deforming due to frictional heat, the cleaning component 13 in this embodiment is configured as a sheet made of polytetrafluoroethylene with a thickness of 1.5 mm. The sheet made of polytetrafluoroethylene with a thickness of 1.5 mm has good high temperature resistance and maintains appropriate flexibility due to its thickness characteristics. Therefore, it can better meet the working requirements of closely contacting the paper feed roller 14 to clean residual ink on the roller surface and not melting and deforming.

[0029] Further, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5 ,by Figure 2 Taking the orientation shown as an example, in this embodiment, in order to enable the cleaning component 13 to adapt to contact with various sizes and models of paper feed rollers 14, so as to meet the cleaning requirements of paper feed rollers 14 used to transport cigarette paper of different sizes, three cleaning mounting through holes 133 are axially equidistantly provided on the cleaning component 13, and the three cleaning mounting through holes 133 are all vertically extending strip-shaped through holes; at the same time, three threaded mounting holes 121 and three mounting bolts 122 are correspondingly equidistantly provided on the mounting fixing rod 12.

[0030] To address this, technicians can pass three mounting bolts 122 through a cleaning mounting through hole 133 and thread them into a threaded mounting hole 121. The nut ends of the three mounting bolts 122 engage with the mounting rod 12 to clamp and fix the cleaning component 13, thus securing the cleaning component 13 onto the mounting rod 12. Simultaneously, since the cleaning mounting through hole 133 is a strip-shaped through hole, technicians can also loosen the three mounting bolts 122 to allow the cleaning component 13 to move downwards in a straight line, enabling it to contact different sizes of paper feed rollers 14.

[0031] Further, please refer to Figure 2 , Figure 3 , Figure 5 ,by Figure 2Taking the orientation shown as an example, in this embodiment, in order for the cleaning component 13 to also be able to rotate around the central axis of the mounting rod 12, so that the cleaning component 13 can also swing to further fit the side surface of the paper feed roller 14 of different sizes; the mounting base 11 is provided with an adjustable clamping mounting hole 111 and a clamping thread structure 112. The adjustable clamping mounting hole 111 includes a cylindrical clamping mounting shaft hole 1111 and an adjustable gap 1112 vertically opened in the upper part of the mounting base 11. The lower end of the adjustable gap 1112 extends and connects to The clamping thread structure 112 extends to the upper end face of the mounting base 11 to form an opening, and includes a threaded connection hole 1121 on the body of the mounting base 11 located on the left side of the adjustable gap 1112, a clamping adjustment through hole 1122 on the body of the mounting base 11 located on the right side of the adjustable gap 1112, and a clamping bolt 1123 that passes through the clamping adjustment through hole 1122 and the adjustable gap 1112 in sequence to engage with the threaded connection hole 1121.

[0032] In this embodiment, the diameter of the clamping mounting hole 1111 is slightly larger than the diameter of the mounting fixing rod 12.

[0033] In response, Figure 2 Taking the orientation shown as an example, technicians can move the clamping bolt 1123 to the right by tightening it, thereby restoring the adjustable gap 1112 to its initial width. At this time, the clamping mounting shaft hole 1111 will also return to its initial diameter. Technicians can then replace the new mounting fixing rod 12, or remove the original mounting fixing rod 12 from the clamping mounting shaft hole 1111 for cleaning and maintenance, or rotate the mounting fixing rod 12 to adjust the orientation angle of the cleaning part 13.

[0034] Similarly, with Figure 2 Taking the orientation shown as an example, technicians can also move the clamping bolt 1123 to the left by tightening it. At this time, with the help of the threaded connection hole 1121, the nut structure at the right end of the clamping bolt 1123 will cooperate with the body of the mounting base 11 located on the left side of the adjustable gap 1112, so as to force the width of the adjustable gap 1112 to become smaller, thereby making the clamping mounting shaft hole 1111 correspondingly smaller, so as to fix the mounting fixing rod 12 inserted therein, restrict its rotation, and ensure that the cleaning part 13 can be stably attached to the side surface of the paper feed roller 14, so as to stably and continuously clean the paper feed roller 14.

[0035] It should be noted that, in this embodiment, in order to facilitate the rotation and replacement of the mounting rod 12, the mounting base 11 is generally not made of hard metal material, but of hard plastic with appropriate toughness and elasticity.

[0036] It should be noted that, in this embodiment, in order to reduce material consumption and facilitate processing and replacement of the cleaning component 13, the upper end of the cleaning mounting hole extends to the upper edge of the cleaning component 13 and forms an opening.

[0037] Further, please refer to Figure 4 In this embodiment, in order to prevent the cleaning component 13 from swinging around the mounting rod 12, the mounting rod 12 is provided with an axial mounting plane 123. The cleaning mounting through hole 133 is provided at the mounting plane 123. When the cleaning component 13 is fixed to the mounting rod 12, the mounting bolt 122 cooperates with the mounting plane 123 instead of the circumferential side surface of the mounting rod 12 to stably clamp and fix the cleaning component 13.

[0038] Anything not mentioned above applies to existing technologies.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
