Description

Technical Field

[0001] This utility model relates to the field of paper tray ring cutting, and in particular to a demolding device for a paper tray ring cutting machine. Background Technology

[0002] In the packaging material processing industry, paper tray ring cutters are key equipment for the production of environmentally friendly packaging materials such as eco-friendly paper trays and honeycomb paper trays. However, traditional paper tray ring cutters have significant shortcomings in terms of production efficiency, automation level, and operational stability, which restricts the further development of the industry.

[0031] Reference Figures 1 to 10 A demolding device for a paper tray ring cutting machine includes a demolding mechanism 7 and a first plate 5. The first plate 5 is used to support the paper tray. The first plate 5 is provided with a first groove 52, which is adapted to the shape of the outer mold 212. The demolding mechanism 7 includes a stop member 71 and a sixth driving member 72 for driving the stop member 71 to reciprocate. The stop member 71 is driven by the sixth driving member 72 to stop the first plate 5, so as to realize the movement of the first plate 5 to separate the formed paper tray and waste from the mold base 21.

[0032] The first plate 5 and the first groove 52 on it allow the mold 212 to pass through and fit against the first plate 5, thus realizing the function of supporting the paper tray. This ensures that the paper tray and waste material can be stably supported after cutting, avoiding shaking and misalignment during the separation process, and improving the stability and reliability of bearing and positioning. By setting the demolding mechanism 7, which includes a stop 71 and a sixth driving member 72, the function of the sixth driving member 72 is to drive the stop 71 to reciprocate, so that the stop 71 can stop the first plate 5 and realize the function of pushing or blocking the movement of the first plate 5. This achieves the effect of reliably separating the formed paper tray and waste material from the mold base 21, avoiding the inefficiency and instability of manual separation, and thus improving the automation level of the separation process and the overall production efficiency.

[0033] Specifically, the demolding device also includes a second plate 62, on which an external mold base 21 is provided. The mold base 21 includes a base 211 and a mold 212.

[0034] Specifically, the first plate 5 has a protrusion 53 on the side near the second plate 62, and the second plate 62 has a second groove 621 for accommodating the protrusion 53. The cooperation between the protrusion 53 and the second groove 621 realizes the limiting and guiding of the first plate 5 and the second plate 62, thereby ensuring the stability and accuracy of the first plate 5 during the movement process, avoiding deviation or misalignment, and improving the reliability of the separation action.

[0035] Specifically, there are two protrusions 53. The two protrusions 53 are located at both ends of the length of the first plate 5 and extend toward the second plate 62. The protrusions 53 are rectangular and housed in the second groove 621, forming a double-point stable limiting effect, which makes the guidance of the first plate 5 more stable during the separation process, thereby improving the stability and durability of the overall demolding device.

[0036] Specifically, the first plate 5 and the second plate 62 are magnetically connected.
