The middle position of the top side of the buffer shell is fixedly connected to the bottom end of the piston rod of the telescopic cylinder. A limiting hole is opened at the center position of the bottom side of the buffer shell, and the limiting hole is connected to the interior of the buffer shell. A fixed column is slidably installed in the limiting hole, and the top end of the fixed column is fixedly connected to a buffer disk, and the buffer disk slides inside the buffer shell. A buffer spring is provided in the buffer shell.

[0007] As a further improvement of this technical solution, the top end of the clamping spring is fixedly connected to the inner wall of the clamping groove, and the bottom end of the clamping spring is fixedly connected to the top side of the clamping strip. The clamping spring drives the clamping strip to move vertically in the clamping groove through a sliding pin.

[0008] As a further improvement of the present technical solution, the bottom end of the fixing column is fixedly connected to the center position of the top side of the clamping block, and the clamping block is driven by the fixing column to slide between the two support plates.

The buffer spring is used to buffer the fixed column and the buffer disk.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] In the automatic die-cutting mechanism for double-sided laminated paper cup-type cardboard, through the disassembly assembly, when replacing the mold, pull the two sliding pins to disengage the upper mold and the clamping strip, slide the upper mold out of the clamping groove, and then slide the new upper mold along the clamping groove. At the same time, the upper mold squeezes the clamping strip. When the upper mold slides in completely, the two clamping springs drive the two sliding pins and the clamping strip to move vertically downward, and at the same time, the clamping strip clamps the upper mold in the clamping groove, thereby reducing equipment downtime, thereby improving productivity and reducing production costs.

[0021] See also Figures 1-4As shown, this embodiment provides an automatic die-cutting mechanism for double-sided laminated paper cup-shaped cardboard, including a bottom plate 1, and support feet are fixedly installed at the four corners of the bottom side of the bottom plate 1. The die-cutting mechanism is stably supported by multiple support feet to prevent the die-cutting mechanism from moving during operation. A lower mold 2 is fixedly installed at the middle position of the top side of the bottom plate 1, and a support plate 3 is fixedly connected to the top side of the bottom plate 1 near the two sides. The top sides of the two support plates 3 are fixedly connected to the receiving plate 4, and the receiving plate 4 is supported by the two support plates 3. The bottom side of the receiving plate 4 A telescopic cylinder 5 is fixedly installed in the middle position, and a disassembly component 6 is provided between the two support plates 3. The upper mold 65 can be quickly replaced by the disassembly component 6 to avoid long equipment downtime and affect the production progress. The disassembly component 6 includes a clamping block 61, which slides between the two support plates 3. At the same time, the two support plates 3 limit the clamping block 61 to avoid the clamping block 61 from offsetting when it moves vertically up and down. A clamping groove is provided on the clamping block 61, and the four corners of the top side of the clamping block 61 are provided. The sliding hole is connected to the card slot, and a sliding pin 62 is slidably installed in the sliding hole. The bottom end of the sliding pin 62 is fixedly connected to the top side of the card strip 63. The outer side of the card strip 63 is provided with a card spring 64. The top end of the card spring 64 is fixedly connected to the inner wall of the card slot. The bottom end of the card spring 64 is fixedly connected to the top side of the card strip 63. The card spring 64 drives the card strip 63 to move vertically in the card slot through the sliding pin 62. An upper mold 65 is slidably installed in the card slot. When replacing the mold, pull the two sliding Pin 62 causes the upper mold 65 and the clamping strip 63 to be disengaged, and the upper mold 65 is slid out of the clamping groove, and then the new upper mold 65 is slid along the clamping groove. At the same time, the upper mold 65 squeezes the clamping strip 63. When the upper mold 65 slides in completely, the two clamping springs 64 drive the two sliding pins 62 and the clamping strip 63 to move vertically downward, and at the same time, the clamping strip 63 clamps the upper mold 65 in the clamping groove. When the equipment is performing die-cutting, the equipment downtime can be reduced, thereby improving productivity and reducing production costs.

[0022] The bottom end of the piston rod of the telescopic cylinder 5 is provided with a buffer assembly 7, which can play a buffering role through the buffer assembly 7 to prevent the upper mold 65 from causing damage to the product due to excessive impact force. The buffer assembly 7 includes a buffer shell 71, and the middle position of the top side of the buffer shell 71 is fixedly connected to the bottom end of the piston rod of the telescopic cylinder 5. A limiting hole is provided at the center position of the bottom side of the buffer shell 71, and the limiting hole is connected to the interior of the buffer shell 71. A fixing column 72 is slidably installed in the limiting hole, and the bottom end of the fixing column 72 is fixedly connected to the top center position of the clamping block 61. The locking cam 73 is fixedly secured to the locking cam 76 and secured to the support cam 76. The locking cam 76 is secured to the support cam 76 with respect to the support cam 76. The cam 76 is secured to the support cam 76 with respect to the support cam 76.

[0023] When the double-sided laminated paper cup type cardboard automatic die-cutting mechanism of this embodiment is used, first, when replacing the mold, pull the two sliding pins 62 to disengage the upper mold 65 from the clamping strip 63, slide the upper mold 65 out of the clamping groove, and then slide the new upper mold 65 along the clamping groove. At the same time, the upper mold 65 squeezes the clamping strip 63. When the upper mold 65 slides in completely, the two clamping springs 64 drive the two sliding pins 62 and the clamping strip 63 to move vertically downward, and at the same time, the clamping strip 63 clamps the upper mold 65 in the clamping groove. When the equipment is performing die-cutting, the buffer shell 71 is driven by the telescopic cylinder 5 to move vertically downward. At the same time, when the upper mold 65 contacts the driven cardboard, the fixed column 72 squeezes the buffer spring 74 through the buffer plate 73, thereby starting the buffering effect.
