Description

Technical Field

[0001] This utility model relates to the technical field of rubber bottle stopper production equipment, and in particular to a bottle stopper film slitting device. Background Technology

[0002] In the production of rubber bottle stoppers, raw rubber sheets are placed in a vulcanizing machine for vulcanization and molding, forming semi-finished bottle stoppers. Afterward, a slitting process is required to separate the stoppers from the semi-finished products, essentially cutting the stoppers off each semi-finished product to form individual bottle stoppers. This process necessitates the use of a slitting device.

[0003] See Figure 1 The slitting device currently used by our company includes a slitting assembly 1, which includes a first template 10 and cylindrical stamping cutters 40. Several stamping cutters 40 are fixedly installed at the bottom of the first template 10. In use, the slitting assembly 1 is installed on the moving parts of the stamping equipment. A perforated plate mold 2 is fixedly installed on the base of the stamping equipment. The perforated plate mold 2 is provided with cutting holes 3 that correspond one-to-one with the positions of the stamping cutters 40. In use, the bottle stopper semi-finished products are laid on the perforated plate mold 2, with each bottle stopper's position corresponding one-to-one with the cutting hole 3. Then, the moving parts of the stamping equipment drive the slitting assembly 1 to move down, and the lower edge of the stamping cutter 40 engages with the upper end of the cutting hole 3, thereby slitting the bottle stopper off a semi-finished film.

[0004] Because the lower edge of the stamping cutter head 40 is matched with the upper port of the cutting hole 3, the stamping cutter head 40 cannot enter the cutting hole 3 too deeply. During use, the cut hole 3 will be blocked by the bottle stopper after slitting, which will cause the next bottle stopper semi-finished product to be laid flat on the perforated plate mold 2.

[0005] Therefore, based on the actual situation on site, our technical staff improved the existing slitting component 1. Utility Model Content

[0037] In the initial state, the fourth template 50 is as follows: Figure 4 As shown, when the cutting assembly 1 moves downward, the fourth template 50 first presses down on the bottle stopper semi-finished product. Then, the first template 10 moves further downward, and the lower end of the punching head 40 extends out from the sliding hole 51, thereby cutting the bottle stopper off the bottle stopper semi-finished product. Afterward, the cutting assembly 1 moves upward, at which point the fourth template 50 returns to its original position under the action of elasticity. Figure 4 state.

[0038] In this embodiment, see Figure 5 The third template 30 has guide shaft holes on both sides. Each guide shaft hole includes a guide hole 33 at the bottom and a limiting hole 34 located above the guide hole 33. The diameter of the limiting hole 34 is larger than the diameter of the guide hole 33. A guide shaft 60 is installed inside the guide shaft holes. A flange 61 is provided at the upper end of the guide shaft 60, and the flange 61 is located inside the limiting hole 34. The lower end of the guide shaft 60 slides downward through the guide hole 33. The lower end of the guide shaft 60 is connected and fixed to the fourth template 50. A spring 62 is fitted onto the guide shaft 60, and both ends of the spring 62 abut against the third template 30 and the fourth template 50, respectively. Through this structure, the fourth template 50 and the third template 30 are elastically and telescopically connected.

[0039] Further, see Figure 5 On the opposite side of the third template 30 and the fourth template 50, and around the guide shaft 60, there is an annular groove 35.
