Description

Technical Field

[0001] The utility model relates to the technical field of raw tapes, in particular to a raw tape packaging shell which is easy to cut. Background Art

[0002] As a common auxiliary product in the installation of liquid pipelines, raw tape is a novel and ideal sealing material that is non-toxic, odorless, and has excellent sealing, insulation and corrosion resistance. It has been widely used in many fields such as water treatment, natural gas, chemical industry, plastics and electronic engineering. Since the raw tape needs to be cut to a specific length according to the interface size of different pipelines to ensure the high airtightness of the pipeline connection, the cutting process of the raw tape is extremely critical to work efficiency and material utilization.

[0003] However, in the traditional packaging method, due to its own toughness, when the raw tape is cut by tearing, the end part often curls due to elastic force, which not only leads to material waste, but also adds to the trouble of construction. Therefore, workers often need to use scissors or knives to make precise cuts. Although this approach can reduce material waste and improve cutting quality, it brings additional inconvenience and potential safety risks. Workers must carry cutting tools at all times, which not only increases the complexity of the work, but also poses the risk of accidentally cutting fingers. In view of this, we propose a raw tape packaging shell that is easy to cut. Utility Model Content

The raw tape reel 1 can rotate relative to the cylinder 20, so that the staff can use the raw tape;

[0031] The top of the outer wall of the annular fixed plate 23 is provided with a cutting assembly 3, which includes a connecting rod 30 fixedly connected to the outer wall of the annular fixed plate 23, a rectangular box 31 is provided at the top of the front side of the connecting rod 30, a moving plate 33 is slidably connected in the rectangular box 31, four springs 35 arranged in a matrix are provided between the bottom of the moving plate 33 and the bottom of the inner wall of the rectangular box 31, a cutter 34 is provided at the bottom of the moving plate 33, and a rectangular hole a310 for the cutter 34 to pass through is opened at the bottom of the rectangular box 31, so that the cutter 34 It can be moved out from the rectangular box 31. A pressing block 36 is provided on the top of the movable plate 33. When the raw tape needs to be cut, the staff presses the pressing block 36 downward, so that the pressing block 36 drives the movable plate 33 and the cutter 34 to move downward, and the cutter 34 cuts the raw tape, thereby facilitating the staff to quickly complete the cutting of the raw tape. The four springs 35 can make the cutter 34 reset upward after use, so that the blade of the cutter 34 moves into the rectangular box 31, to prevent the cutter 34 from accidentally cutting the raw tape.

[0032] In this embodiment, a threaded tube 21 is provided at the front end of the cylinder 20, and an annular limiting plate 22 is threadedly connected to the outer side of the threaded tube 21. The front and rear sides of the raw tape reel 1 are respectively fitted with the opposite sides of the annular limiting plate 22 and the annular fixing plate 23, so that the annular limiting plate 22 can be disassembled and assembled, so as to facilitate the staff to disassemble and assemble the raw tape reel 1.

[0033] Specifically, an arc-shaped bottom plate 32 is provided on the front side of the connecting rod 30 and near the bottom of the rectangular box 31. The concave surface of the arc-shaped bottom plate 32 fits with the convex surface of the raw tape reel 1. The convex surface of the arc-shaped bottom plate 32 is provided with an avoidance groove 320 for avoiding the cutter 34. The length of the cutter 34 is greater than the width of the raw tape. The raw tape passes between the arc-shaped bottom plate 32 and the rectangular box 31. When the cutter 34 cuts the raw tape, the blade of the cutter 34 is located in the avoidance groove 320, thereby ensuring that the cutter 34 completely cuts the raw tape. The cutter 34 generates pressure on the arc-shaped bottom plate 32, and the raw tape reel 1 supports the arc-shaped bottom plate 32, thereby improving the stability of the arc-shaped bottom plate 32.

[0034] Furthermore, four first annular positioning blocks 311 arranged in a matrix are provided at the bottom of the inner wall of the rectangular box 31 , and the bottom ends of the four springs 35 are respectively located in the four first annular positioning blocks 311 , which play a positioning role for the bottom ends of the four springs 35 .
