Description

Technical Field

[0001] This utility model belongs to the technical field of cigarette packaging equipment, specifically relating to a lubrication device for trademark paper. Background Technology

[0002] In the packaging process of small cigarette packs, the original packaging equipment did not have a device to lubricate the surface of the label paper. Because the label paper was coated with glue, the thickness of the adhesive parts was increased. During the conveying, gluing and folding process, the corresponding thickened parts were prone to friction with the conveying channel, resulting in scratches.

[0003] To address the issues of scratches and wear that easily occur during the packaging of label paper, current technologies employ a label paper lubrication device. This device applies lubricant to the back of the label paper corresponding to the adhesive side, reducing friction during transport and minimizing the possibility of scratches and wear. However, existing label paper lubrication devices primarily consist of a felt-covered support structure. This felt-based lubrication structure design, over time, requires the entire felt sheet to be replaced if it deforms beyond its limits, resulting in a lengthy replacement process. Therefore, an improved label paper lubrication device is necessary. Utility Model Content

[0004] The purpose of this invention is to provide a label paper lubrication device to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A label paper lubrication device is provided for lubricating label paper when installed on a label paper conveying channel. It includes a support and a felt assembly. A pressure roller and a coating roller are rotatably mounted on the support, with a gap between the pressure roller and the coating roller for the label paper to pass through. Notches are provided on the support at both ends of the lower side of the coating roller, and clamping assemblies are installed on these notches. The felt assembly is mounted on the support via the clamping assemblies, and the felt on the top of the felt assembly contacts the coating roller. A height adjustment assembly is provided at the bottom of the support, which cooperates with the clamping assemblies to adjust the height of the felt assembly.

[0007] In this application, the height adjustment component, in conjunction with the clamping component, can flexibly adjust the height of the felt, achieving height compensation when the felt is worn out, improving the utilization rate of the felt and its fit with the coating roller; allowing the felt to fully contact the coating roller, lubricating the label paper conveyed through the gap on the label paper conveying channel; as the felt deforms and needs to be replaced over time, the clamping component, by clamping the felt component, can change the clamping state of the clamping component on the felt by operating the clamping component, facilitating the disassembly and assembly of the felt, thus making it convenient for operators to replace the felt; it is highly practical.

[0008] Furthermore, the felt assembly includes a mounting shell with a mounting opening at the top, and the felt is detachably mounted on the mounting opening. This allows for convenient disassembly of both the felt assembly and the felt itself.

[0009] Furthermore, the felt is provided with lubricating grease; or, the mounting housing is provided with an oil cavity, and an oil passage is provided between the oil cavity and the mounting port, through which the lubricating oil contained in the oil cavity is transported to the felt. The oil passage is configured as follows: a through hole is formed between the oil cavity and the mounting port, and an oil-absorbing cotton core thread is disposed within the through hole, capable of absorbing the lubricating oil contained in the oil cavity and transporting it to the felt inside the mounting port.

[0010] Furthermore, one end of the mounting shell is provided with a first limiting inclined surface symmetrically positioned vertically, and the top of the other end of the mounting shell is provided with a second limiting inclined surface; the clamping assembly includes an adjusting rod, which is installed on the outside of one of the notches of the bracket, and a passive limiting inclined block that abuts against the first limiting inclined surface is fitted on the adjusting rod, and a spring is installed between the adjusting rod and the passive limiting inclined block; an adjusting component is installed on the outside of the other notch of the bracket, and an active limiting inclined block is installed at the bottom end of the adjusting component, and the adjusting component drives the active limiting inclined block to abut against the second limiting inclined surface; the adjusting component is an actuator or an adjusting bolt. The first limiting inclined surface has a vertical limiting groove, which slides with the adjusting rod to horizontally limit and vertically guide the mounting shell.

[0011] Furthermore, the height adjustment assembly includes a connecting plate and an elastic support pair. The elastic support pair is mounted on the bottom of the bracket via the connecting plate, and slides against the bottom of the mounting shell to elastically support the mounting shell. The spring's elastic support of the passive limiting wedge can work in conjunction with the active limiting wedge to adjust the height of the mounting shell, and this height adjustment is relatively free. Simultaneously, the elastic support pair also elastically supports the bottom of the mounting shell, achieving height compensation for felt deformation or wear, thus improving the utilization rate of the felt.

[0012] Furthermore, a guide groove is provided at the bottom of the mounting shell, and the elastic support pair slides in conjunction with the guide groove; the elastic support pair is a linear array of spring sheets integrally formed; the guide groove can improve the accuracy of the mounting shell during installation.

[0013] The utility model adopting the above technical solution has the following advantages:

[0014] In this application, the felt assembly is clamped by a clamping component during use. This clamping method facilitates the installation and disassembly of the felt assembly, improving efficiency and making it easier for operators to replace the felt. A height adjustment component works in conjunction with the clamping component to adjust the height of the felt assembly, thereby adjusting the adhesion between the felt and the label paper. This lubrication of the non-adhesive surfaces of the label paper reduces friction between the label paper and the conveyor channel during transport, protecting the label paper. Furthermore, the clamping component and the height adjustment component work directly together, offering flexible and convenient functional adjustments and a compact structural connection. The overall structure is simple, low-cost, and highly practical. Attached Figure Description

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0026] like Figures 1-5 As shown in the figure, a label paper lubrication device according to an embodiment of the present invention is used to lubricate label paper on a label paper conveying channel 102. It includes a support 100 and a felt assembly 103. The support 100 is installed on the label paper conveying channel 102, and a pressure roller 101 and a coating roller 106 are rotatably mounted on the support 100, positioned opposite each other. The pressure roller 101 and the coating roller 106 are located on the upper and lower sides of the label paper conveying channel 102. The power of the coating roller 106 can be shared with a stepper motor on the label paper conveying channel 102. A gap is left between the pressure roller 101 and the coating roller 106 for the label paper to pass through. When the label paper passes through the gap, the pressure roller 101 applies downward pressure to ensure that the coating roller 106 can contact the label paper and apply coating to lubricate it. Notches 105 are provided on the supports 100 at both ends of the lower side of the paint roller 106. Clamping components 200 are installed on the notches 105. The felt assembly 103 is installed on the support 100 through the clamping components 200. The felt 1032 on the top of the felt assembly 103 is in contact with the paint roller 106. Lubricant, such as fixing paraffin, can be provided on the felt 1032. After the fixing paraffin is applied to the label paper, it can reduce the friction between the label paper and the label paper conveying channel 102, and also reduce the friction between the label paper and the components of the subsequent process, thus protecting the label paper. A height adjustment component 300 is provided at the bottom of the support 100. The height adjustment component 300 works with the clamping components 200 to adjust the height of the felt assembly 103.

[0027] In this embodiment, the felt assembly 103 includes a mounting shell 1031, with a mounting opening at the top of the mounting shell 1031. The felt 1032 is detachably mounted in the mounting opening. When the felt assembly 103 is inserted into the notch 105 of the bracket 100 from one side notch, the felt 1032 is first mounted in the mounting opening; then the felt assembly 103 is inserted and clamped and fixed by the clamping assembly 200. The height adjustment assembly 300 includes a connecting plate 104 and an elastic support pair 301. The elastic support pair 301 is mounted on the bottom of the bracket 100 via the connecting plate 104, and slides with the bottom of the mounting shell 1031, elastically supporting the mounting shell 1031.

[0028] In practice, the bracket 100 and the connecting plate 104 can be integrally formed from a single sheet of material. Threaded holes are machined on the bracket 100 and the connecting plate 104, allowing the bracket 100 to be installed onto the label paper conveying channel 102. Rotating holes are then machined on the bracket 100, through which the pressure roller 101 and the coating roller 106 are installed. When the coating roller 106 does not share the power of the label paper conveying channel 102, a drive motor can be installed independently on the bracket 100 to drive the coating roller 106.

[0029] Among them, the elastic support pair 301 is a linear array of spring sheets integrated together; the spacing of the linear array is less than the length of a single spring sheet. In this way, the middle part of the elastic support pair 301 can provide concentrated elastic support force, and the two ends of the elastic support pair 301 can provide reduced elastic support force. This facilitates the insertion of the mounting shell 1031 and the cooperation with the clamping assembly 200.

[0030] In this embodiment, a guide groove 1035 is provided at the bottom of the mounting shell 1031, and the elastic support pair 301 slides in the guide groove 1035; the elastic support pair 301 is limited in the guide groove 1035, which improves the docking accuracy between the mounting shell 1031 and the clamping assembly 200 during the installation process; the mounting shell 1031 can also be limited when applying lubricating coating, and the clamping assembly 200 can limit the relative position of the felt 1032.

[0031] In this embodiment, an oil cavity may also be provided inside the mounting shell 1031, and an oil passage may be provided between the oil cavity and the mounting opening. The lubricating oil contained in the oil cavity is transported to the felt 1032 through the oil passage and the mounting opening. The oil passage is configured as follows: a through hole is formed between the oil cavity and the mounting opening, and an oil-absorbing cotton core wire is provided in the through hole. The oil-absorbing cotton core wire can absorb the lubricating oil contained in the oil cavity and transport it to the felt 1032 in the mounting opening; thus supplying oil to the felt 1032 and replenishing the wear caused by the felt 1032 brushing oil onto the paint roller 106.

[0032] In this embodiment, one end of the mounting shell 1031 is provided with a first limiting inclined surface 10311 that is symmetrically positioned vertically, and the top of the other end of the mounting shell 1031 is provided with a second limiting inclined surface 10312; the clamping assembly 200 includes an adjusting rod 205, which is installed on the outside of one of the notches 105 of the bracket 100 (i.e., Figure 2 (On the left side of the bracket 100), mounting plates can be welded to the upper and lower notches 105 of the bracket 100. Holes are made on the mounting plates to install the adjusting rod 205. The adjusting rod 205 is fitted with passive limiting inclined blocks that abut against the first limiting inclined surface 10311. The two passive limiting inclined blocks are the upper passive limiting inclined block 204 and the lower passive limiting inclined block 206. A spring 302 is installed between the adjusting rod 205 and the passive limiting inclined blocks. The two ends of one spring 302 abut against the bottom wall of the upper mounting plate 203 and the top wall of the upper passive limiting inclined block 206. The two ends of the other spring 302 abut against the top wall of the lower mounting plate 203 and the bottom wall of the lower passive limiting inclined block 204. Under the elastic support of the springs 302, the upper passive limiting inclined block 204 and the lower passive limiting inclined block 206 both exhibit a tendency to compress the symmetrical first limiting inclined surface 10311, thereby clamping one end of the mounting shell 1031. The other notch 105 on the outside of the stent 100 (i.e. Figure 2 An adjusting component is installed on the right side of the mounting shell 1031. An active limiting inclined block 201 is installed at the bottom of the adjusting component. The adjusting component drives the active limiting inclined block 201 to abut against the second limiting inclined surface 10312. The other end of the mounting shell 1031 is clamped, and the two passive limiting inclined blocks cooperate to achieve complete clamping of the mounting shell 1031.

[0033] In practice, this embodiment can select actuator 202 as the adjusting component based on cost or needs. Actuator 202 can specifically be an electric actuator or a pneumatic actuator. This, combined with a conventional microcontroller, achieves automated control of height adjustment.

[0034] In order to reduce costs, such as Figure 6 As shown, in this embodiment, the adjusting component can also be selected as the adjusting bolt 2021 as needed; a mounting plate is welded and installed above the notch 105 on the right side of the bracket 100, and an adjusting nut is fixed on the mounting plate 203. The adjusting bolt 2021 is screwed into the adjusting nut, and a retaining ring extends out from the bottom of the mounting plate and is connected to it. The retaining ring is rotatably engaged with the top of the active limiting inclined block 201; the downward pressing height of the active limiting inclined block 201 is adjusted by adjusting the adjusting bolt, and the second limiting inclined surface 10312 is abutted.

[0035] In this embodiment, a feed inlet 1033 is provided on the side of the mounting shell 1031 near the second limiting inclined surface 10312. The feed inlet 1033 is connected to the oil cavity and supplies oil to the oil cavity. A plug can be installed on the feed inlet 1033 to achieve closure. A disassembly and installation force application port 1034 is machined on the bottom of the mounting shell 1031 below the feed inlet 1033. The disassembly and installation force application port 1034 is not connected to the feed inlet 1033 or the oil cavity. The disassembly and installation force application port 1034 facilitates the application of pulling force to pull out the mounting shell 1031 for convenient replacement of the felt 1032.

[0036] In this embodiment, as Figure 4 , Figure 7 As shown, a limiting groove is vertically formed on the first limiting inclined surface 10311. The limiting groove slides with the adjusting rod 205 to limit the horizontal position and guide the vertical position of the mounting shell 1031. This ensures that after the felt assembly 103 is clamped by the clamping assembly 200, the height adjustment of the height adjustment assembly 300 does not affect the clamping effect.

[0037] This structural design, through the height adjustment component 300 and the clamping component 200, allows for flexible adjustment of the height of the felt 1032. This enables height compensation for wear and tear on the felt 1032, improving its utilization rate and adhesion to the coating roller 106. It also ensures full contact between the felt 1032 and the coating roller 106, lubricating the label paper conveyed through the gaps in the label paper conveying channel 102. As the felt 1032 deforms and needs replacement over time, the clamping component 200, by clamping the felt component 1032, allows for easy adjustment of the clamping state, facilitating the installation and removal of the felt 1032. The overall structure is simple and highly practical.

[0038] The above provides a detailed description of a trademark paper lubrication device provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
