Description

Technical Field

[0001] This utility model relates to the field of cutting equipment, and in particular to a die-cutting device for a drain bowl lid. Background Technology

[0002] Drain bowl lids are commonly used sealing products on convenience foods (including but not limited to instant rice noodles). The structure of commonly used drain bowl lids is shown in patent publication document CN114474941B. The common manufacturing method for this type of drain bowl lid is to first use a film composite molding, and then punch holes where holes are needed. After punching, the easy-open sheet is cut. This method of punching holes first and then cutting the easy-open sheet has two problems: first, the work efficiency is relatively low; second, film may remain at the hole opening after the hole is made, which leads to a certain probability of jamming when the final drain bowl lid is used. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a die-cutting device for drain bowl lids. It employs a cutting base plate with a blade and a cutting pressure plate to squeeze the bowl lid sheet from both sides, allowing the bowl lid sheet to be cut into shape in one go. Furthermore, the probability of residual film on the drain holes after the bowl lid is die-cut is relatively low.

[0004] The technical solution adopted by this utility model is as follows: A die-cutting device for drain bowl lids includes a frame, telescopic rods, a cutting base plate, and a cutting pressure plate. The cutting base plate is mounted on the frame, and the telescopic rods are mounted on the frame. There are multiple telescopic rods distributed around the cutting base plate. The cutting pressure plate indirectly cooperates with the telescopic ends of the telescopic rods. The cutting base plate has a bottom plane with several closed protruding cutting edges. The cutting pressure plate has a pressing plane with open U-shaped cutting edges and a cutting blade. The bottom plane has a receiving groove with the same size and shape as the cutting blade.

[0005] In this die-cutting device, the telescopic rod extends and retracts, causing the cutting pressure plate to move towards the cutting base plate. When a drain bowl lid needs to be cut, the lid piece is first placed on the cutting base plate. Then, the telescopic rod extends and retracts, causing the cutting pressure plate to move towards the cutting base plate. When the bottom surface of the cutting base plate and the pressing surface of the cutting pressure plate are pressed against the lid piece from both sides, the closed-shaped raised cutting edge on the bottom surface cuts out the drain holes on the lid piece. The U-shaped cutting edge on the pressing surface cuts out the easy-open sheet on the lid piece. Then, the cutting edge on the pressing surface and the receiving groove on the bottom surface together cut out the shape of the lid piece. During cutting, the cutting edge is located in the receiving groove. Furthermore, in this die-cutting device, because a closed-shaped raised cutting edge is used to cut out the drain holes, compared to the piercing and punching method, film is less likely to remain at the drain holes.

[0006] In summary, this die-cutting device uses a cutting base plate with a blade and a cutting pressure plate to squeeze the bowl lid sheet from both sides, which can cut the bowl lid sheet into shape in one go. Moreover, the probability of residual film on the drain hole after the bowl lid is die-cut is relatively low.

[0007] Optionally, the cutting blade is a closed cutting blade, and the receiving groove is a closed receiving groove.

[0008] Optionally, it also includes a bottom support plate, which is disposed on the frame platform, and the cutting base plate is disposed on the bottom support plate.

[0009] Optionally, the bottom support plate is provided with a clamping groove, and the cutting bottom plate is clamped in the clamping groove by its own protrusion.

[0010] The cutting base plate is clamped onto the clamping groove of the base support plate by its own protrusions. This facilitates the replacement of different cutting base plates when needed and also facilitates maintenance. Specifically, the clamping groove is a square-shaped groove, and the protrusions on the cutting base plate are adapted to the shape of the clamping groove.

[0011] Optionally, an auxiliary mesh plate is also included, which is engaged with the telescopic end of the telescopic rod, and the cutting pressure plate is directly or indirectly disposed on the auxiliary mesh plate.

[0012] Optionally, a transition plate is also included, which is disposed on the auxiliary mesh plate. The transition plate has a slot, and the cutting pressure plate has an embedding part that is inserted and engaged with the slot.

[0013] The cutting plate is engaged with the slot on the transition plate through its own embedded part. This makes it easy to replace the cutting plate with different sizes when needed, and also facilitates maintenance. The slot is an isosceles trapezoidal slot, and the embedded part on the cutting plate is adapted to the shape of the slot.

[0014] Optionally, a rotating roller is rotatably mounted on the platform.

[0015] The function of the rotating roller is to guide and clamp the bowl lid piece before cutting and the drain bowl lid formed after cutting.

[0016] Optionally, a suspension guide plate is provided on the platform.

[0017] The function of the suspension guide plate is to guide the cut drain bowl lid.

[0018] Optionally, there are four telescopic rods, which are parallel and do not contact each other, and are arranged in a rectangular shape.

[0019] The four telescopic rods can drive the cutting pressure plate to move stably relative to the cutting base plate.

[0020] The beneficial effects of this utility model are: by using a cutting base plate with a blade and a cutting pressure plate to squeeze the bowl lid piece from both sides, the bowl lid piece can be cut into shape in one go, and the probability of residual film on the drain hole after the bowl lid is die-cut is relatively low.

When a drain bowl lid needs to be cut, the bowl lid is first placed on the cutting base plate 7. Then, the telescopic rod 3 extends and retracts, causing the cutting pressure plate 8 to move towards the cutting base plate 7. When the bottom surface of the cutting base plate 7 and the pressing surface of the cutting pressure plate 8 are pressed against the bowl lid from both sides, the closed-shaped protruding blade 701 on the bottom surface cuts out the drain hole on the bowl lid.
