Technical Field

[0001] This utility model relates to the field of tape cutting technology, and in particular to a tape cutting device. Background Technology

[0002] In the packaging industry, tape plays an important role in both sealing the outer packaging of products and securing the inner packaging. In the electronics industry, tape is used to fix and insulate electronic components and to mask circuit boards during production. In the construction and decoration industry, tape can be used for sealing and bonding decorative materials. In daily life, people also frequently use tape for pasting and repairing items.

[0003] Place the tape ring in the device, apply the tape to the desired location, and cut the tape after application.

[0004] Existing tape cutting devices are not convenient for clamping tape rings of different diameters, thus they cannot accommodate a large number of tape rings. They also lack the function of clamping tape rings in the right position. Therefore, a tape cutting device has been developed. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0028] Example 1

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a tape cutting device, including a housing 1, a shrinking structure 2 provided in the inner cavity of the housing 1, a limiting mechanism 3 provided inside the housing 1, a cutting blade 5 fixedly installed on one side of the housing 1, and an auxiliary roller 4 installed in the inner cavity of the housing 1.

[0030] The shrinking structure 2 includes a rotating shaft 201 rotatably mounted on the inner surface of the housing 1, a rotating cylinder 203 movably mounted on the inner surface of the rotating shaft 201, and a plurality of semi-circular blocks 205 distributed on the outer circumference of the rotating cylinder 203.

[0031] The inner surface of the housing 1 is circumferentially distributed with sliding plates 202 adapted to the semi-circular dome block 205, and connecting rods 204 are symmetrically installed at the bottom of the semi-circular dome block 205.

[0032] Specifically, since the number of slide plates 202 is the same as the number of semi-circular blocks 205, one end of the semi-circular block 205 moves inside the slide plate 202, while the other semi-circular blocks 205 slide in the corresponding slide plate 202, thereby changing the expansion size of the three semi-circular blocks 205, thus having fixed tape rings of different diameters.

[0033] Limiting rings 206 are fixedly connected to both sides of the rotating drum 203. A first spring 208 is provided on the side of the limiting ring 206 opposite to the housing 1. A nut 207 is threadedly connected to one end of the rotating shaft 201.

[0034] Specifically, by manually tightening the nut 207, the rotating drum 203 is pushed inward. At this time, the first spring 208 is compressed. When the rotating drum 203 moves, with the assistance of the slide plate 202, the two connecting rods 204 move the semi-circular dome block 205 upward inside the slide plate 202, thereby changing the degree of expansion of the semi-circular dome block 205, thus having the function of changing the expansion size of the three semi-circular dome blocks 205.

[0035] One side of the semi-circular dome block 205 is slidably connected to the inside of the slide plate 202, the other end of the connecting rod 204 is rotatably connected to the outside of the rotating cylinder 203, the first spring 208 is located on the outside of the rotating shaft 201, and the nut 207 is located on one side of another limiting ring 206.

[0036] Furthermore, manually rotating the nut 207 presses the rotating drum 203 inward. As the rotating drum 203 moves, it compresses the first spring 208, causing it to deform. The rotating drum 203 pushes the multiple semi-circular blocks 205 on the outside to expand outward. At this time, one end of the semi-circular block 205 moves in the slide plate 202. Under the action of the first spring 208, the expanded semi-circular block 205 is stabilized to prevent it from moving in the opposite direction, thus adapting to tape rings of different sizes.

[0037] Example 2

[0038] Reference Figure 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment and includes a limiting mechanism 3 that can stabilize and clamp the tape ring.

[0039] The limiting mechanism 3 includes a hole 302 on the outside of the housing 1, a slider 305 is movably installed inside the hole 302, and a baffle 301 is fixedly connected to one side of the slider 305 in the inner cavity of the housing 1.

[0040] A number of grooves 307 are provided on one side of the hole 302. A second spring 304 is provided inside the groove 307. A limit ball 303 is fixedly installed at one end of the second spring 304. A push handle 306 is fixedly connected to the side of the slider 305 located outside the housing 1.

[0041] Specifically, since multiple limiting balls 303 are arranged in multiple grooves 307, and since a second spring 304 is provided on one side of each limiting ball 303, when the slider 305 moves to the side of any limiting ball 303, the limiting ball 303 is pushed into the slider 305 under the action of the second spring 304, thereby restricting the movement of the slider 305.

[0042] The slider 305 is slidably connected inside the hole 302, and the limiting ball 303 is slidably connected in the inner cavity of the groove 307. The limiting ball 303 is adapted to the slider 305.

[0043] Specifically, manually pushing the push handle 306 causes the slider 305 to move in the hole 302, which in turn moves the baffle 301 to block tape rings of different thicknesses, thereby stabilizing and clamping the tape rings, thus facilitating clamping.

[0044] Furthermore, manually push the push handle 306, which drives the slider 305 to move in the hole 302, thereby driving the baffle 301 to move. Under the action of the second spring 304, the limiting ball 303 is pushed into the slider 305, restricting the slider 305 from moving in the hole 302. After the baffle 301 is moved to a suitable position, it is convenient to clamp the tape ring.

[0045] Working principle: Holding the handle at the top of the housing 1, first place the tape loop around the outside of multiple sliders 305, then manually push the push handle 306. The push handle 306 drives the sliders 305 to move, and the sliders 305 drive the baffle 301 to move within the cavity of the housing 1. As the sliders 305 move, under the action of the second spring 304, the second spring 304 pushes the limiting ball 303 into the sliders 305, controlling the stability of the sliders 305. Under the action of the baffle 301, the tape loop is positioned at a suitable position on the semi-circular dome block 205. After controlling the tape loop to a suitable position, manually turn the nut 207 to push the rotating cylinder 203 inward. At this time, the rotating cylinder 203 pushes the limiting ring 206 to move, thereby compressing the first spring 208. As the rotating cylinder 203 moves, it pushes several connecting rods 204 on the outside. One end is pushed forward. Since one end of the semi-circular dome 205 is controlled in the slide plate 202, when the end of the connecting rod 204 connected to the rotating drum 203 moves, the semi-circular dome 205 can be pushed upward, pushing all three semi-circular domes 205 to the inside of the tape ring. Since the outer side of the semi-circular dome 205 is serrated, the tape ring is clamped in an expanding form under the action of multiple semi-circular domes 205. Under the action of the first spring 208, the limiting ring 206 is pushed in the opposite direction. The limiting ring 206 pushes the rotating drum 203, preventing the semi-circular dome 205 from shrinking inward. After stabilizing the tape ring, the tape is pulled off the tape ring. One end of the tape is moved from the top of the auxiliary roller 4. After the tape is used, the handle is held and pushed downward with force. Under the action of the cutting blade 5, the tape is cut.
