[0041] To fully understand this application, detailed steps and structures will be presented in the following description to illustrate the technical solution of this application. Preferred embodiments of this application are described in detail below; however, in addition to these detailed descriptions, this application may have other implementation methods.

[0042] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 5As shown in the preferred embodiment of this application, a multi-mode concealed cutter includes a base 1, a first film roll assembly 2, and a second film roll assembly 3. The base 1 is made of high-strength plastic. The first film roll assembly 2 includes a first tape reel 21. The second film roll assembly 3 is disposed on one side of the first film roll assembly 2. The first film roll assembly 2 and the second film roll assembly 3 provide tapes of different specifications. The second film assembly 3 includes a housing 31, a second tape reel 32 located within the housing 31, and a cutter 4 disposed on the extension line of the connection line between the first tape reel 21 and the second tape reel 32. The housing 31 also includes a first transition wheel 5 and a second transition wheel 6 located above the second tape reel 32. The first transition wheel 5 is disposed near the first tape reel 21, and the second transition wheel 6 is disposed near the cutter 4. The cutter has at least a first cutting mode and a second cutting mode. In the first cutting mode, the cutter is configured such that the tape on the first tape reel 21 passes sequentially above the first transition wheel 5 and below the second transition wheel 6 to be cut by the cutter 4. In the second cutting mode, the cutter is configured such that the tape on the second tape reel 32 passes through the second transition wheel 6 to be cut by the cutter 4.

[0043] Understandably, the different specifications mentioned above include differences in tape type, width, length, etc. It should be noted that in this embodiment, the tape length of the first film roll assembly 2 is greater than the length of the second film roll assembly 3. This is to allow for the use of the second film roll assembly 3 when a small amount of tape is needed (i.e., the second cutting mode), or the use of the first film roll assembly 2 when a large amount of tape is needed (i.e., the first cutting mode). In other embodiments, the tape on the first film roll assembly 2 and the second film roll assembly 3 may also have other differences, determined according to the actual situation.

[0044] Understandably, by setting the cutter 4 on the extension line connecting the first tape reel 21 and the second tape reel 32, the cutter can guide the position of the tape cutter 4 without complex mechanical transmission or position adjustment when switching between the two cutting modes, which simplifies the overall structure of the cutter and reduces production costs and maintenance difficulty.

[0045] Understandably, by setting the first film roll assembly 2 and the second film roll assembly 3, as well as the first transition wheel 5 and the second transition wheel 6, the cutter has at least two cutting modes, which can meet the needs of different tape types and cutting requirements, greatly improving the versatility and practicality of the cutter, and avoiding the inconvenience and time waste caused by replacing the cutter or adjusting the equipment.

[0046] For example, when it is necessary to cut the tape on the first tape reel 21, the cutter is adjusted to the first cutting mode. At this time, the tape on the first tape reel 21 passes sequentially above the first transition wheel 5 and below the second transition wheel 6. The first transition wheel 5 prevents the tape on the first tape reel 21 from contacting the second tape assembly 3, facilitating cutting by the cutter 4. Specifically, the tape on the first tape reel 21 is first pulled out a section, then one end of the tape is wrapped around the first transition wheel 5 from above, and then passed under the second transition wheel 6, making the tape adhere tightly to the surface of the second transition wheel 6. The end of the tape is then pulled to the cutter 4, where it is cut by the cutter 4, completing one cutting operation. During this process, the tape maintains a stable running path under the guidance of the first transition wheel 5 and the second transition wheel 6, ensuring cutting accuracy. When it is necessary to cut the tape on the second tape reel 32, the cutter is adjusted to the second cutting mode. At this time, the tape on the second tape reel 32 passes under the second transition wheel 6 to be cut by the cutter 4. The operating method is as follows: pull out the tape from the second tape reel 32, pass the tape directly under the second transition wheel 6 so that the tape contacts the second transition wheel 6, and then pull the tape to the cutter 4 for cutting. Due to the positional design of the second transition wheel 6, the tape can naturally adhere to the transition wheel during operation, ensuring smooth cutting.

[0047] Furthermore, in the height direction, the connecting line formed by the top end of the first transition wheel 5 and the bottom end of the second transition wheel 6 does not coincide with the second tape reel 32, so that the tape on the first tape reel 21 will not interfere with the second tape reel 32 during operation, ensuring that the tape can smoothly pass through the first transition wheel 5 and / or the second transition wheel 6 and reach the cutter 4 position.

[0048] Furthermore, the housing 31 includes a lower housing 311 and an upper housing 312 rotatably connected to the lower housing 311. The first transition wheel 5 and the second transition wheel 6 are connected to the upper housing 312. In this embodiment, the lower housing 311 is a box-shaped structure with an upward opening, and the upper housing 312 is a semi-circular cover. The two are rotatably connected by a pivot 7, so that the upper housing 312 can rotate around the pivot 7, facilitating the opening and closing of the housing 31 for the installation and replacement of internal components such as the second tape reel 32 and the transition wheels.

[0049] In this embodiment, the upper housing 312 has a two-half structure, and the two halves of the upper housing 312 are rotatably connected to the lower housing 311 respectively. The purpose of this arrangement is to simplify the manufacturing process of the housing 31 on the one hand, and to facilitate the replacement of the first tape reel 21 and the guidance of the tape through it on the other hand, thereby improving the maintainability and replaceability of the components.

[0050] Furthermore, both the first film assembly 2 and the second film assembly 3 are detachably mounted on the base 1. Specifically, the first film assembly 2 is detachably mounted on the base 1 using bolts 8. (Reference) Figure 4 As shown, the cutter also includes a pair of fixing components 9 mounted on both sides of the base 1. Each fixing component 9 includes a connecting plate 91 connected to the base 1 and a fixing member 92 disposed through the connecting plate 91. The fixing member 92 can move closer to or away from the housing 31 under the action of external force to fix or loosen the housing 31. Specifically, the fixing member 92 includes an operating part 921 and a supporting part 922 connected to the operating part 921. The supporting part 922 is used to support the housing 31. The operating part 921 is provided with threads. When it is necessary to fix the housing 31, the operating part 921 is tightened so that the supporting part 922 fits tightly against the outer surface of the housing 31. When it is necessary to loosen the housing 31, the operating part 921 is loosened so that the supporting part 922 moves away from the housing 31, thereby facilitating the installation and removal of the second film assembly 3.

[0051] It should be noted that, in this embodiment, in addition to the two modes mentioned above, the cutter can also be used separately by disassembling the entire second film roll assembly 3.

[0052] Understandably, a rubber gasket may be provided on the supporting part 922 to prevent damage caused by hard contact between the supporting part 922 and the housing 31, while the operating part 921 is provided with threads to increase the friction between the force application part and the operating part 921, thereby making it easy to fix the housing 31.

[0053] Furthermore, the second film assembly 3 also includes a first gear 10 and a second gear 11, at least partially located within the housing 31; the cutter 4 is connected to a rack 12, the first gear 10 engages with the rack 12, and the second gear 11 meshes with the first gear 10. The tape contacts the second gear 11 to drive the second gear 11 and the first gear 10 to rotate, thereby exposing the cutter 4 to the outside of the housing 31. In this embodiment, the cutter 4 is also provided with a counterweight to drive the cutter 4 back into the housing 31.

[0054] Furthermore, the rack 12 includes a toothed portion 121 located at the top and a smooth portion 122 located below the toothed portion 121. This arrangement is designed to meet the needs of the user in different situations. For example, in one scenario, the user can continuously rub the tape against the second gear 11 to drive the first gear 10 and the second gear 11 to rotate until the cutter 4 is delivered to the top through the toothed portion 121 of the rack 12, and the tape is cut by the cutter 4. In another scenario, the user can continuously rub the tape against the second gear 11 to drive the first gear 10 and the second gear 11 to rotate until the cutter 4 is delivered to the top through the toothed portion 121 of the rack 12. Afterward, the angle at which the tape is pulled out can be controlled so that the tape continues to rub against the second gear 11. At this time, the first gear 10 will not mesh with the toothed portion 121, but will correspond to the smooth portion 122 of the rack 12, until the tape needs to be cut by the cutter 4.

[0055] It should be noted that since the tape is constantly rubbing against the second gear 11, the first gear 10 is also constantly subjected to the force from the tape. This force can counteract the gravity of the counterweight and keep the cutter 4 always exposed. After the tape is cut, the friction between the tape and the second gear 11 is removed. Under the action of the counterweight, the first gear 10 and the second gear 11 are driven to rotate in opposite directions, so that the cutter 4 retracts into the housing 31.

[0056] Furthermore, the tape is formed at an angle by the second transition wheel 6, with the angle being 100°-150°, preferably 130°, so that the tape can maintain appropriate tension during cutting while also achieving a labor-saving effect.

[0057] The above is only one specific implementation of this application, and any other improvements made based on the concept of this application shall be considered within the scope of protection of this application.
