Description

Technical Field

[0001] The present invention relates to a cutter structure, and in particular to a cutter structure for cutting labels fed from a printing device. Background Art

[0002] With the advancement of society and the rapid development of industry, labels are widely used in supermarket retail, clothing tags, logistics labels, public transportation tickets, pharmaceutical labels, and barcode printing. However, most label printers currently available are only suitable for printing labels with a backing paper. This backing paper must be removed before the label is affixed to the object. While these backing paper labels meet most needs, the backing paper is discarded after use, resulting in wasted resources and increased costs. Furthermore, these backing paper labels are relatively complex to use.

[0003] In light of this, the use of linerless labels as a substrate for label printing has gradually become a trend. Linerless labels not only make label printing more environmentally friendly, but also eliminate the liner, allowing more labels to be printed per roll, reducing waste and contributing to environmental sustainability. Furthermore, linerless labels require less raw material, resulting in a lesser impact on the environment. Eliminating the liner also benefits label printing by reducing storage space requirements and lowering transportation, storage, and raw material management costs.

[0004] Currently, there are more and more linerless labels. During use, the adhesive on the linerless labels is very easy to adhere to other components such as the cutter and the cardboard. If the adhesive of the linerless labels adheres to the cutter, it will directly affect the service life of the cutter. The current solution on the market is to oil the cutter to reduce the adhesion of the adhesive, but most of the oiling is a one-time application (that is, oiling when the cutter is made). The cutter is not oiled during use. Even if it is oiled during use, it is done manually, which is very inconvenient. Whether it is a one-time application or manual oiling during use, after the oil stains on the cutter surface are exhausted, the label adhesive and label debris will stick to it. The adhesive and label debris will make the cutter blunt and easy to damage, thereby reducing the cutting life of the cutter.

[0005] Therefore, how to improve the above-mentioned problems has become a focus of relevant personnel in this field. Summary of the Invention

[0006] One of the objectives of the present invention is to provide a cutting knife structure that effectively prevents the cutting knife from being contaminated by residual glue or foreign matter, thereby extending the service life of the cutting knife.

[0007] Other purposes and advantages of the present invention can be further understood from the technical features disclosed in the present invention.

[0008] In order to achieve one or part or all of the above-mentioned purposes or other purposes, the present invention provides a cutter structure for cutting labels fed from a printing device. The cutter structure includes a shell, a cutter assembly and a lubrication assembly. The shell includes an opening. The cutter assembly is arranged in the shell. The cutter assembly includes a base and a movable knife arranged on the base. The movable knife can be raised and lowered relative to the base to cut the label, and the movable knife is exposed from the opening. The lubrication assembly includes a support frame and at least one oil-absorbing material arranged on the support frame. The oil-absorbing material includes lubricating oil. The lubrication assembly is pivotally connected to the shell by the support frame, so that the oil-absorbing material extends into the opening and contacts the movable knife of the cutter assembly, and during the process of the movable knife being raised and lowered, the lubricating oil of the oil-absorbing material adheres to the movable knife.

[0009] In one embodiment of the present invention, the support frame of the lubrication assembly can pivot relative to the housing between a first position and a second position. When the support frame is in the first position, the oil-absorbing material extends into the opening and contacts the movable tool. When the support frame pivots from the first position to the second position, the support frame drives the oil-absorbing material out of contact with the movable tool.

[0010] In one embodiment of the present invention, the support frame of the lubricating assembly is pivotally connected to the housing in a detachable manner.

[0011] In one embodiment of the present invention, the support frame of the lubricating assembly includes at least one accommodating portion for accommodating the oil absorbing material.

[0012] In one embodiment of the present invention, the oil-absorbing material is felt or porous foam material.

[0013] In one embodiment of the present invention, the weight of the lubricating oil in the oil absorbing material is between 5 grams and 7 grams.

[0014] In one embodiment of the present invention, the cutting blade structure further includes an anti-adhesion layer. The anti-adhesion layer covers the surface of the support frame of the lubricating component.

[0015] In one embodiment of the present invention, the above-mentioned shell also includes a paper outlet port and a guide plate body, the paper outlet port and the opening correspond to each other, the guide plate body extends from the opening and is located above the lubrication assembly, a paper feed port corresponding to the paper outlet port is defined between the guide plate body and the lubrication assembly, and the base of the cutter assembly defines a channel between the paper feed port and the paper outlet port.

[0016] In one embodiment of the present invention, the lubrication assembly further comprises a roller assembly, which is disposed on the support frame and located above the oil absorbing material. The roller assembly and the guide plate of the housing correspond to each other and define a paper feed port.

[0017] In one embodiment of the present invention, the cutting blade structure further includes an anti-adhesion layer, the roller assembly includes a plurality of rollers, and the anti-adhesion layer covers the surfaces of the rollers.

[0018] In one embodiment of the present invention, the cutter assembly further comprises a fixed cutter, which is disposed on the base and located above the movable cutter. The movable cutter engages with the fixed cutter during the upward movement to cut the label.

[0019] In one embodiment of the present invention, the above-mentioned cutting knife assembly also includes a hollow area, which is opened on the base and corresponds to the opening of the shell. The movable knife is exposed from the hollow area, and the oil-absorbing material of the lubrication assembly extends into the opening and the hollow area and contacts the movable knife.

[0020] In one embodiment of the present invention, the label is a linerless label.

[0021] The cutter structure of an embodiment of the present invention comprises an oil-absorbing material containing lubricating oil mounted on a detachable and pivotable support frame. The lubricating oil-absorbing material is then pre-pressed against the movable blade of the cutter assembly. As the movable blade of the cutter assembly reciprocates, it continuously contacts and rubs against the oil-absorbing material. The lubricating oil in the oil-absorbing material adheres to the movable blade, achieving continuous lubrication of the movable blade. This ensures that the surface of the movable blade remains lubricated and prevents it from being contaminated by adhesive residue or foreign matter generated by cutting labels. This effectively keeps the movable blade clean and prolongs the life of the blade. The cutter structure of the embodiment of the present invention is particularly effective in addressing the large amount of adhesive residue generated when cutting linerless media. By maintaining the surface of the movable blade in a continuously lubricated state, the surface of the movable blade is protected from contamination by rapidly generated adhesive residue.

[0054] like Figures 1 to 7 As shown, the cutter structure 1 of this embodiment is, for example, configured on one side of a printing device (not shown), but the present invention does not limit the relative configuration position between the cutter structure 1 and the printing device. The cutter structure 1 of this embodiment is used to cut labels fed from the printing device. In this embodiment, the labels fed by the printing device are, for example, linerless media labels, but the present invention is not limited to this. The detailed structure of the printing device capable of producing labels is well known in the art and will not be described in detail. The detailed structure of the cutter structure 1 of this embodiment is further described below.

[0055] like Figures 1 to 7As shown, the cutter structure 1 of this embodiment includes a housing 10, a cutter assembly 11 and a lubricating assembly 12. The housing 10 includes an opening 100. The cutter assembly 11 is disposed in the housing 10, and the cutter assembly 11 includes a base 111 and a movable knife 112 disposed on the base 111. The movable knife 112 of the cutter assembly 11 can be raised and lowered relative to the base 111, and cuts the labels fed by the printing device during the upward movement of the movable knife 112, and the movable knife 112 is exposed from the opening 100 of the housing 10. The lubricating assembly 12 includes a support frame 121 and at least one oil-absorbing material 122 disposed on the support frame 121. Lubricating oil is adsorbed in the oil-absorbing material 122.

[0056] In this embodiment, the cutter assembly 11 further includes a hollow area 1110. The hollow area 1110 of the cutter assembly 11 is formed in the base 111 and corresponds to the opening 100 of the housing 10. The movable blade 112 is exposed through the hollow area 1110. The oil-absorbing material 122 of the lubricating assembly 12 extends into the opening 100 of the housing 10 and the hollow area 1110 of the cutter assembly 11, directly contacting the movable blade 112.

[0057] In this embodiment, the lubricating assembly 12 is pivotally connected to the housing 10 by the support frame 121, so that the lubricating assembly 12 can be pivotally moved relative to the housing 10 and can be opened in the open state (such as Figure 7 ) and the closed state (as shown Figure 2 When the lubrication assembly 12 is in the closed position relative to the housing 10, the lubrication assembly 12 covers the opening 100 of the housing 10. The oil-absorbing material 122 of the lubrication assembly 12 extends into the opening 100 of the housing 10 and the hollow area 111 of the base 111, directly contacting the movable blade 112 of the cutter assembly 11. As the movable blade 112 moves up and down relative to the base 111, lubricating oil absorbed by the oil-absorbing material 122 adheres to the movable blade 112, coating the side surfaces and blade edge (tip) of the movable blade 112 with lubricating oil, achieving a lubricating effect.

[0058] Specifically, the support frame 121 of the lubricating assembly 12 can pivot relative to the housing 10 between a first position P1 and a second position P2. Figure 2 and Figure 5 As shown, when the support frame 121 is located at the first position P1, that is, the relative position between the lubricating assembly 12 and the housing 10 is in a closed state, the oil absorbing material 122 on the support frame 121 extends into the opening 100 of the housing 10 and the hollow area 1110 of the base 111 and contacts the movable knife 112 of the cutting assembly 11. Figure 7As shown, when the support frame 121 pivots from the first position P1 to the second position P2, that is, when the lubrication assembly 12 and the housing 10 are in an open state relative to each other, the support frame 121 drives the oil absorbing material 122 to break away from contact with the movable knife 112 of the cutter assembly 11.

[0059] As described above, the advantage of the lubricating assembly 12 pivoting relative to the housing 10 and switching between an open and closed state is that the user only needs to pivot the lubricating assembly 12 relative to the housing 10 to the open state to replace or add lubricant to the oil-absorbing material 122 located on the support frame 121, and to simultaneously clean the movable blade 112 of the cutter assembly 11. Furthermore, it is worth mentioning that the lubricating assembly 12 of this embodiment is, for example, pivotally connected to the housing 10 in a detachable manner. In other words, the lubricating assembly 12 can be directly removed from the housing 10. This not only facilitates replacement of the oil-absorbing material 122 or addition of lubricant, but also facilitates further cleaning of the support frame 121 or the direct replacement of the support frame 121 with a new one.

[0060] As can be seen from the above description, the cutter structure 1 of this embodiment secures the oil-absorbing material 122 to the support frame 121 and pre-presses the oil-absorbing material 122 against the movable blade 112 of the cutter assembly 11. As the movable blade 112 continuously rises and falls to cut labels, it continuously rubs against the oil-absorbing material 122. Lubricating oil absorbed by the oil-absorbing material 122 continuously adheres to the movable blade 112, thereby lubricating the movable blade 112. It is worth noting that, after actual testing, the cutter structure 1 of this embodiment has been verified to remain lubricated even after cutting 100,000 high-viscosity linerless labels, without becoming contaminated by the adhesive backing of the linerless labels or by label debris. In other words, the cutter structure 1 of this embodiment does not require frequent lubrication during use, effectively resolving the issues associated with conventional lubrication methods, such as one-time lubrication or frequent manual lubrication during use.

[0061] In this embodiment, the housing 10 includes a front cover 101 and a rear cover 102 assembled together. The front cover 101 and the rear cover 102 are assembled together to define a housing space, and the opening 100 of the housing 10 is formed in the rear cover 102. The cutter assembly 11 is disposed within the housing space of the housing 10, and the lubrication assembly 12 is pivotally connected to the rear cover 102 of the housing 10. In other words, the lubrication assembly 12 pivots relative to the rear cover 102 of the housing 10 to switch between an open state and a closed state.

[0062] In this embodiment, the oil-absorbing material 122 of the lubricating assembly 12 is made of felt because it is structurally stable, non-deformable, and highly elastic. These properties ensure reliable contact and contact with the movable cutter 112. In this embodiment, the lubricating oil absorbed by the oil-absorbing material 122 is silicone oil because silicone oil is resistant to high and low temperatures, resists oxidation, and has low volatility, allowing the oil-absorbing material 122 to maintain its oil content for a long time.

[0063] It should be noted that the use of felt as the oil-absorbing material 122 is merely one embodiment of the present invention and is not intended to be limiting. In other embodiments, the oil-absorbing material 122 may alternatively be a porous foam material. The use of silicone oil as the lubricating oil is merely one embodiment of the present invention and is not intended to be limiting. In other embodiments, the lubricating oil may alternatively be other oils having similar properties to silicone oil.

[0064] like Figure 4 As shown, the support frame 121 of the lubrication assembly 12 of this embodiment includes at least one receiving portion 1210. Each receiving portion 1210 is used to accommodate an oil-absorbing material 122. In this embodiment, the number of oil-absorbing materials 122 is, for example, three, and the number of receiving portions 1210 of the support frame 121 corresponds to the number of oil-absorbing materials 122. When these oil-absorbing materials 122 are accommodated in their corresponding receiving portions 1210, the lubricating oil absorbed by the oil-absorbing materials 122 is prevented from leaking outwards when squeezed. This ensures that the lubricating oil absorbed by the oil-absorbing materials 122 adheres securely to the movable blade 112 of the cutter assembly 12.

[0065] It is worth noting that in this embodiment, the weight of the lubricating oil absorbed by the oil-absorbing material 122 is between 5 grams and 7 grams. When the lubricating assembly 12 and the housing 10 are in a closed position relative to each other, such that the oil-absorbing material 122 contacts the movable cutting tool 112, the oil-absorbing material 122 is not squeezed, causing the absorbed lubricating oil to overflow and contaminate other components besides the movable cutting tool 112. In other words, the lubricating oil in the oil-absorbing material 122 can fully adhere to and lubricate the movable cutting tool 112.

[0066] like Figure 1 、 Figure 2 Figure 5 and Figure 6As shown, the housing 10 of this embodiment further includes a paper outlet port 103 and a guide plate 104. The paper outlet port 103 is provided in the front cover 101 of the housing 10, and corresponds to the opening 100 provided in the rear cover 102. The guide plate 104 extends from the opening 100 of the rear cover 102 and is located above the lubrication assembly 12. A paper feed port 105 corresponding to the paper outlet port 103 is defined between the guide plate 104 and the lubrication assembly 12. In this embodiment, the base 111 of the cutter assembly 11 disposed within the housing 10 defines a channel C between the paper outlet port 103 and the paper feed port 105. Linerless labels fed from a printing device (not shown) can enter the channel C from the paper feed port 105. The linerless labels are cut to an appropriate size by the movable cutter 112 that rises within the channel C and are then output through the paper outlet port 103.

[0067] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, the lubrication assembly 12 of this embodiment further includes a roller assembly 123. The roller assembly 123 is disposed on the support frame 121 and positioned above the oil-absorbing material 122. In this embodiment, the roller assembly 123 of the lubrication assembly 12 and the guide plate 104 of the housing 10 face each other and define the aforementioned paper feed port 105. The roller assembly 123 of the lubrication assembly 123 guides linerless labels fed from the printing device through the paper feed port 105 and into the channel C.

[0068] like Figure 5 and Figure 6 As shown, the cutter assembly 11 of this embodiment also includes a fixed cutter 113. The fixed cutter 113 of the cutter assembly 11 is configured on the base 111 and is located above the movable cutter 112, that is, the fixed cutter 113 and the movable cutter 112 are respectively located at corresponding upper and lower positions. When the linerless labels fed from the printing device enter the channel C from the paper feed port 105, the movable cutter 112 fits with the fixed cutter 113 during the upward movement, and then cuts the linerless labels located in the channel C into appropriate sizes. It should be noted that when the movable cutter 112 fits with the fixed cutter 113 during the upward movement, the lubricating oil attached to the movable cutter 112 is also attached to the fixed cutter 113, so that the fixed cutter 113 is also lubricated.

[0069] It is worth mentioning that, in order to prevent adhesive residue from remaining on related components during the process of guiding linerless labels from the paper feed port 105 of the housing 10 into the channel C, in this embodiment, an anti-adhesive layer (not shown) can be applied to the roller assembly 123 of the lubrication assembly 12. Specifically, the anti-adhesive layer is applied to the surfaces of the multiple rollers of the roller assembly 123. When the roller assembly 123 guides the linerless labels fed from the printing device from the paper feed port 105 into the channel C, the anti-adhesive layer applied to the roller assembly 123 effectively prevents the adhesive of the linerless labels from adhering to these rollers. Furthermore, the anti-adhesive layer can also be sprayed onto the surface of the support frame 121 of the lubrication assembly 12 to further prevent the adhesive of the linerless labels from adhering to the support frame 121 of the lubrication assembly 12. In this embodiment, the anti-adhesive layer is, for example, a UV-curable coating (e.g., UV lacquer), but the present invention is not limited thereto.

[0070] In summary, the cutter structure of the present invention is characterized by mounting an oil-absorbing material containing lubricating oil on a detachable and pivotable support frame, and further pre-pressing the lubricating oil-absorbing material against the movable blade of the cutter assembly. As the movable blade of the cutter assembly performs a reciprocating motion, the movable blade continuously contacts and rubs against the oil-absorbing material. The lubricating oil in the oil-absorbing material continuously adheres to the movable blade, achieving continuous lubrication of the movable blade. This ensures that the surface of the movable blade remains lubricated and prevents adhesion to residual adhesive or foreign matter generated by cutting labels, thus maintaining a long-term cleanliness of the movable blade and extending the life of the blade. The cutter structure of the present invention is particularly effective in addressing the large amount of residual adhesive generated when cutting linerless media. By maintaining the surface of the movable blade in a continuously lubricated state, the movable blade is prevented from becoming stuck to by the rapidly generated residual adhesive.

[0071] The cutting knife structure of the embodiment of the present invention also has the following advantages: 1. The cutting knife structure does not need to use a space-consuming trough to store lubricating oil. It only needs to control the amount of lubricating oil (5 grams to 7 grams) and apply it on the felt, so that it can directly contact the movable tool to achieve the lubrication effect. 2. The lubrication component can be disassembled from the housing, that is, the support frame that fixes the oil-containing felt is pivoted relative to the housing and then opened, thereby facilitating the replacement of the felt and the cleaning of the movable tool. 3. In order to ensure that the linerless labels can be smoothly transported without sticking to the path, a roller group is added to the lubrication component to reduce the resistance of the adhesive backing of the linerless labels on the moving path. 4. In order to prevent the adhesive backing of the linerless labels from remaining on the path during the transport process, an anti-sticking layer is sprayed on the relevant components and roller group to prevent the adhesive backing from sticking.

[0072] However, the above is only a preferred embodiment of the present invention, and it cannot be used to limit the scope of implementation of the present invention. That is, all simple equivalent changes and modifications made according to the claims of the present invention and the content of the invention description are still within the scope of the patent of the present invention.
