AI Technical Summary
Existing pomelo cake demolding devices tend to cause pomelo cakes to stick together when using the cutting tool for demolding, resulting in uneven cutting and distorted cuts, leading to waste and a decline in the quality of the finished product.
An automatic demolding device was designed. Through the cooperation of the mold and the demolding component, the protective component is used to prevent the pomelo cake from sticking to the demolding component. During the demolding process, the powder replenishing device applies icing around the pomelo cake to prevent sticking. At the same time, the corrugated rod and the impact block are used to prevent blockage in the demolding frame.
This process ensures smooth demolding of pomelo cake, keeps the cut surface clean, avoids waste, improves the appearance quality of the finished product, and prevents blockage during demolding.

Description
Technical Field
[0001] This utility model relates to the field of demolding pomelo cakes, and more specifically, it relates to an automatic demolding device. Background Technology
[0002] Pomelo cake is a traditional dessert. To make it, pomelo pulp, sugar, pectin and water are put into a mixing tank in proportion and mixed evenly. Then, the pomelo paste is injected into molds through an automatic filling machine, cooled and shaped, then unmolded, and finally cut into standard sizes and packaged by an automatic cutting machine.
[0003] Existing demolding devices use blades to assist in demolding. However, when using blades for demolding, the pomelo cake sticks to the blades, making the cutting process rough and causing twisting at the cut. As a result, the twisted part needs to be discarded in the next cutting and packaging step to ensure product quality, leading to waste of pomelo cake.
[0004] Therefore, a new solution is needed to address this problem. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic demolding device. When demolding pomelo cake, the mold and demolding components can cooperate to remove the pomelo cake. When removing the pomelo cake, it can prevent the pomelo cake from sticking to the demolding components, thus making the demolding smoother and keeping the cut surface clean, thereby avoiding waste and improving the appearance of the finished product.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automatic demolding device includes a base, belt rollers rotatably connected to both sides of the base, and a motor fixedly connected to the base. The output shaft of the motor is fixedly connected to one end of one of the belt rollers. The two belt rollers are connected by a conveyor belt. A mold for holding pomelo paste is placed on the conveyor belt. A demolding component for removing pomelo cake is provided on the base.
[0007] The demolding assembly includes an electric slide rail fixedly connected to the base, a slider slidably connected to the electric slide rail, a demolding frame fixedly connected to the slider, and trigger rods fixedly connected to both sides of the demolding frame. The demolding frame is provided with a protective component to prevent the pomelo cake from sticking to the demolding frame.
[0008] Several stabilizing rods are fixedly connected to the base, and several fixing blocks are fixedly connected to the demolding frame. The fixing blocks are slidably connected to adjacent stabilizing rods.
[0009] A sliding rod is slidably connected to the stabilizer rod, and an impact block is fixedly connected to the sliding rod. A pressure spring is sleeved between the impact block and the stabilizer rod on the sliding rod. A corrugated rod is fixedly connected to the fixed block. When the impact block contacts the protrusion of the corrugated rod, the pressure spring is in a deformed state.
[0010] The present invention is further configured such that: the mold includes a support frame placed on a conveyor belt, a holding plate slidably connected on the support frame, two positioning rods fixedly connected on the support frame, and an elastic sheet fixedly connected on the positioning rods; the holding plate is provided with two through holes through which the elastic sheet can pass.
