Technical Field

[0001] The utility model relates to the technical field of heat shrink tube processing, in particular to a fixed-length shearing device used for heat shrink tube processing. Background Art

[0002] Heat shrink tubing is a special polyolefin heat shrink tubing. The outer layer is made of high-quality soft cross-linked polyolefin material and the inner layer is made of hot melt adhesive. The outer layer material has the characteristics of insulation, corrosion resistance, and wear resistance. The inner layer has the advantages of low melting point, waterproof sealing and high adhesion. Heat shrink tubing needs to be sheared and cut during the production process to meet production needs.

[0003] The existing Chinese patent with announcement number CN214818788U discloses a shearing device for heat shrink tube segmentation, including an operating table, a material pressing mechanism is movably installed on the outer side of the operating table, a guide rod is fixedly installed on the inner top wall of the operating table, an auxiliary motor is fixedly installed inside the operating table and is located on the right side of the guide rod, the output end of the auxiliary motor is transmission-connected to an auxiliary roller with one end extending above the operating table, and two hollow plates are fixedly installed on the top of the operating table and are located on the right side of the guide rod.

[0004] Although the adjustment process of the above scheme is cumbersome and difficult to control, it wastes time and energy and is inconvenient to use. However, according to different usage requirements, the length of the heat shrink tube is not fixed. The shearing device lacks precise fixed-length shearing when processing the heat shrink tube, resulting in the inability to meet the processing requirements well. Therefore, it does not meet the existing needs. In this regard, we propose a fixed-length shearing device for heat shrink tube processing. Utility Model Content

[0005] The purpose of the utility model is to provide a fixed-length cutting device for heat shrink tube processing, so as to solve the problem that the shearing device proposed in the above background technology lacks accurate fixed-length cutting when processing heat shrink tubes, resulting in failure to meet processing requirements.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model provides an upper clamping block above the lower clamping block. The user can pull the handle at the upper end of the upper clamping block to make the upper clamping block drive the second connecting block to move upward. The upward movement of the second connecting block will drive the lifting plate to compress the reset spring. At this time, the heat shrinkable tube can be placed between the lower clamping block and the upper clamping block. After releasing the handle, the upper clamping block can be moved downward by the elastic restoring action of the reset spring, so the heat shrinkable tube can be conveniently clamped and fixed. The user only needs to release the fixation of the heat shrinkable tube by pulling up the handle, so that the fixation of the heat shrinkable tube is convenient and quick.

[0017] 2. The utility model has linear guides installed on both sides inside the main body, and a first connecting block is arranged between the linear guides. When the heat shrink tube is cut, the heat shrink tube can be fixed by clamping the lower clamping block and the upper clamping block. The user can adjust the length of the heat shrink tube according to the length on the scale according to the cutting requirement. After the adjustment, the linear guide is started. The high precision of the linear guide ensures that the heat shrink tube can be moved accurately, so that the heat shrink tube is moved to the bottom of the shearing mechanism for shearing, so that the heat shrink tube can be cut according to the required length, which can meet different production requirements and is easy to use.

[0018] 3. The utility model opens a collecting chamber on the lower side of the main body, and the cut heat shrink tube will fall into the collecting chamber and the collecting box by gravity. The heat shrink tube can be guided by a triangular block to avoid accumulation directly below the falling point and affecting subsequent collection. The user only needs to open the rotating door to take out the collecting box, making discharge more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] When in use, the upper clamping block 8 can be moved downward by the elastic action of the reset spring 12, so that the heat shrink tube can be clamped and fixed, and the zero degree mark of the scale 5 faces the front side, so that the required length of the heat shrink tube can be positioned according to the extended length of the heat shrink tube after clamping, and then the heat shrink tube can be moved to the bottom of the shearing mechanism 3 by the linear guide rail 4, and shearing can be performed by the shearing mechanism 3, which can meet different production needs and is easy to use.

[0030] See also Figure 4 and Figure 5 The front and rear sides of the transmission cavity 9 are welded with guide rods 10, which penetrate the lifting plate 11 and slide with the lifting plate 11. The setting of the guide rods 10 can limit the axial position of the lifting plate 11 to prevent the movement of the lifting plate 11 from being offset;

[0031] See also Figure 4 and Figure 5, a return spring 12 is sleeved on the upper side of the outer portion of the guide rod 10, one end of the return spring 12 is connected to the transmission chamber 9, and the other end of the return spring 12 is connected to the lifting plate 11, and the upper clamping block 8 can be moved downward by the elastic action of the return spring 12, so as to clamp and fix the heat shrink tube;

The shearing mechanism 3 is started again to cut the heat shrink tube, thereby realizing the fixed-length shearing of the heat shrink tube to meet different production needs. It is easy to use. The cut heat shrink tube will fall into the collection box 16 inside the collection chamber 15 through gravity. The triangular stopper 17 inside the collection box 16 can prevent the heat shrink tube from accumulating just below the falling point and affecting subsequent collection. The user only needs to open the rotating door 18 to take out the collection box 16, making the discharge more convenient.
