Description

Technical Field

[0001] The utility model relates to the technical field of blister punching and cutting, and more specifically to a blister shell punching and cutting device which is easy to adjust. Background Art

[0002] Blister forming is a plastic processing technology. The main principle is to heat and soften the flat plastic sheet, then use vacuum adsorption to the mold surface, and then cool it to form. It is widely used in plastic packaging, lighting, advertising, decoration and other industries. After the blister product is finalized, the excess part of the blister shell needs to be punched and separated by a punching device for subsequent use.

[0003] Based on the above, the inventors found that when the existing punching device is in use, the punching die is mainly driven by the cylinder to press down the blister die to complete the punching work of the blister shell. Since the punching speed of the punching die driven by the cylinder is relatively fast, the punching die wears relatively quickly and needs to be replaced frequently. The punching die is integrated and has a large weight, and it is inconvenient to adjust each time it is replaced. Therefore, in view of this, the existing structure is studied and improved, and a punching device for blister shells that is easy to adjust is provided, in order to achieve a more practical purpose.

[0026] Example:

[0027] See also Figure 1-5 , a punching device for a blister shell that is easy to adjust, comprises a frame 1, a blister template 2 is fixedly connected to the top surface of the frame 1 in the center, and two cylinders 4 are fixedly connected just above the frame 1, and the output ends of the two cylinders 4 are fixedly connected to the same punching mold 5, a sliding groove 6 is opened inside the punching mold 5, and a clamping block 7 is clamped in the center of the sliding groove 6, and a cutter 8 is fixedly connected to the bottom surface of the clamping block 7, and limiting blocks 9 are arranged on both sides of the clamping block 7, and a group of guide rods 10 are fixedly connected to the center of the outer sides of the two limiting blocks 9, and a handle 12 is fixedly connected to the outer side of the limiting block 9 on the outer side of the two limiting blocks 9, a self-locking spring 11 is sleeved on the outer side of the guide rod 10, and a synchronous adjustment mechanism 3 is arranged on the upper side of the opposite surfaces of the two limiting blocks 9, a flat plastic hard sheet is placed on the top surface of the blister template 2, and heated blister is carried out, and then the cylinder 4 is started to drive the punching mold 5 to descend, and the cutter 8 punches the excess part of the blister product.

[0028] See also Figure 5 The synchronous adjustment mechanism 3 includes a tooth column 13, both ends of which are fixedly connected to a limit ring 14, and the upper and lower sides of the tooth column 13 are respectively meshed and connected with a first connecting plate 15 and a second connecting plate 16. In order to facilitate the disassembly and replacement of the clamping block 7 and the cutter 8, a synchronous adjustment mechanism 3 is provided.

[0029] See also Figure 2 The limit block 9 is located inside the sliding groove 6, and the limit block 9 is slidably connected to the sliding groove 6 in the horizontal direction. The clamping block 7 is inserted into the sliding groove 6 from bottom to top. During the movement, the clamping block 7 squeezes the inclined surface of the limit block 9, so that the limit block 9 moves outward, and at the same time, the limit block 9 compresses the self-locking spring 11.

[0030] See also Figure 4 The guide rod 10 and the handle 12 both pass through the punching die 5, and the two ends of the self-locking spring 11 are fixedly connected to the limit block 9 and the inner surface of the sliding groove 6 respectively, until the slot on the side of the clamping block 7 and the limit block 9 move to the same horizontal height. Under the action of the self-locking spring 11, the limit block 9 is reset and clamped with the clamping block 7, so that the position of the clamping block 7 and the cutter 8 is fixed.

[0031] See also Figure 4 The limit block 9 is connected to the clamping block 7, and the inner side of the limit block 9 is inclined downward, and the movement stability of the limit block 9 is ensured by the guide rod 10.

[0032] See also Figure 5 The tooth column 13 is located inside the sliding groove 6, and the tooth column 13 is movably connected to the sliding groove 6. Pulling the two handles 12 outward drives the outer limit block 9 to move outward, and simultaneously moves the first connecting plate 15.

Under the action of the tooth column 13, the second connecting plate 16 and the inner limit block 9 are synchronously moved in the opposite direction, and the two limit blocks 9 are respectively separated from the two sides of the clamping block 7. Then, the clamping block 7 automatically falls from the inside of the sliding groove 6 under the action of gravity, completing the disassembly of the clamping block 7.

[0034] When in use: insert the clamping block 7 into the sliding groove 6 from bottom to top. During the movement, the clamping block 7 squeezes the inclined surface of the limit block 9 to move the limit block 9 outward. At the same time, the limit block 9 compresses the self-locking spring 11. The guide rod 10 ensures the movement stability of the limit block 9 until the clamping groove on the side of the clamping block 7 and the limit block 9 move to the same horizontal height. Under the action of the self-locking spring 11, the limit block 9 is reset and clamped with the clamping block 7, so that the position of the clamping block 7 and the cutter 8 is fixed. Then, the flat plastic hard sheet is placed on the top surface of the blister template 2 for heating and blistering. Then, the cylinder 4 is started to drive it. The punching die 5 descends, and the excess part of the blister product is punched out by the cutter 8. When the cutter 8 is severely worn and needs to be replaced, the two handles 12 are pulled outward to drive the outer limit block 9 to move outward, and the first connecting plate 15 is moved synchronously. Under the action of the tooth column 13, the second connecting plate 16 and the inner limit block 9 are moved in the opposite direction synchronously. The two limit blocks 9 are separated from the two sides of the clamping block 7 respectively, and the clamping block 7 automatically falls from the inside of the sliding groove 6 under the action of gravity, completing the disassembly of the clamping block 7 and the cutter 8, and the new cutter 8 can be installed.
