Description

Technical Field

[0001] This utility model relates to the field of biscuit filling technology, and in particular to a biscuit filling injection machine. Background Technology

[0002] Sandwich cookies are cookies with a filling of butter, egg yolk, or red bean paste in the center. To make them, first, a mixture of flour and water is kneaded into a dough, which is then baked in an oven. Afterward, the filling is inserted into the center of the dough, and the two cookie pieces are gently pressed together.

[0003] The biscuits commonly used in sandwich biscuits are usually called "single slices" in factories. Their production process is the same as that of regular sweet biscuits. Nowadays, automated filling machines are mostly used to inject the prepared filling material into the upper center of the single slice when filling it. However, the extruded filling material does not adhere evenly and stably to the single slice, and is often a thick blob. As a result, when the single slices are stacked and sandwiched, the degree of outward diffusion is different, making it difficult to keep the spread between the single slices even. It is also easy for the filling material to be extruded to the outside of the single slice during the sandwiching process, causing waste and corresponding contamination problems. Utility Model Content

[0004] The purpose of this invention is to provide a biscuit filling injection machine that can maintain a uniform and stable attachment shape, ensuring that it spreads evenly to the outside during the subsequent single-piece stacking and clamping process, thereby uniformly adhering to the surface of the single piece and avoiding the problem of excessive filling material on one side being squeezed out to the outside.

[0005] To achieve the above objectives, a biscuit filling injection machine is provided, comprising: an injection platform, a working groove on the lower right side of the injection platform, a conveyor belt slidably fitted to the bottom of the working groove in a front-to-back direction, a plurality of single pieces being placed equidistantly on the conveyor belt, an automatic filling machine fitted into the top right side of the injection platform, a filling nozzle fixedly connected to the bottom center of the automatic filling machine, a filling tube fixedly connected to the bottom output end of the filling nozzle, the bottom end of the filling tube penetrating downward through the injection platform and vertically mounted on the lower layer of the working groove, a slip ring slidably fitted to the outer side of the filling tube, an electric push rod mounted on the top left side of the slip ring, and limiting telescopic rods symmetrically mounted on the top right side of the slip ring, the upper ends of the electric push rod and the limiting telescopic rods being embedded in and fixedly connected to the inner wall of the injection platform, the bottom output end of the electric push rod and the bottom telescopic end of the limiting telescopic rod being perpendicular to the slip ring. The bottom of the slip ring is fixedly connected to an isolation ring sleeve. The inner surface of the semi-enclosed structure formed by the slip ring and the isolation ring sleeve is covered with a layer of anti-adhesion polymer film. By setting the slip ring and the isolation ring sleeve to form a frustum-shaped semi-enclosed space on the outside of the core injection tube, and using an electric push rod to control the slip ring to slide up and down along the outside of the core injection tube, the isolation ring sleeve can be attached to the upper side of the single piece to form a frustum-shaped enclosed space before the single piece on the conveyor belt below is injected. Then, the core material is injected through the core injection tube and filled into the enclosed space, thereby shaping the core material on the single piece into a frustum shape. Then, the electric push rod drives the isolation ring sleeve to mechanically and uniformly detach from the single piece and the core material on it at an upward speed, maintaining a uniform and stable attachment shape, ensuring that it diffuses evenly to the outside in the subsequent single piece stacking and clamping process, thereby uniformly adhering to the surface of the single piece and avoiding the problem of excessive core material on one side being squeezed out to the outside.

[0006] According to the aforementioned biscuit filling injection machine, an elastic washer is fixedly wrapped around the bottom outer edge of the isolation ring, and the bottom of the elastic washer is pressed and adhered to the upper surface of the biscuit. This avoids the problem of breakage caused by hard pressure on the biscuit.

[0007] According to the aforementioned biscuit filling injection machine, a limiting sleeve is fixedly connected to the top center of the slip ring, and the inner side of the limiting sleeve slides vertically with the filling tube. This helps maintain the vertical movement of the slip ring and the isolation ring sleeve.

[0008] According to the aforementioned biscuit filling injection machine, a feeding port is fixedly connected to the top left side of the automatic filling machine, and a sealing cap is threaded onto the outer side of the top of the feeding port. This facilitates the replenishment of filling material at any time.

[0009] According to the aforementioned biscuit filling injection machine, a gas balancing valve is fixedly connected to the top right side of the automatic filling machine. This valve balances the internal and external air pressure, preventing the formation of negative pressure inside.

[0010] According to the biscuit filling injection machine, a counterweight pad is fitted and mounted on the outer bottom of the injection platform, and a rubber pad is fixedly attached to the bottom of the counterweight pad. This lowers the overall center of gravity while maintaining the anti-slip stability of the bottom.

[0011] According to the aforementioned biscuit filling injection machine, a dustproof top is erected parallel to the conveyor belt directly above it, and the dustproof top is fixedly connected to the injection table. This provides dust protection for the individual biscuits and filling materials transported below.

[0012] The above-mentioned solution has the following beneficial effects:

[0013] In this invention, a slip ring is used in conjunction with an isolation ring to form a frustum-shaped semi-enclosed space on the outside of the core injection tube. An electric push rod controls the slip ring to slide up and down along the outside of the core injection tube. This allows the isolation ring to be attached to the upper side of the single piece before the single piece on the lower conveyor belt is injected to form a frustum-shaped enclosed space. Then, the core material is injected through the core injection tube and filled into the enclosed space, thus shaping the core material on the single piece into a frustum shape. Afterward, the electric push rod drives the isolation ring to mechanically and uniformly detach from the single piece and its core material at an upward speed, maintaining a uniform and stable attachment shape. This ensures that the core material spreads evenly to the outside during the subsequent single piece stacking and clamping process, thus uniformly adhering to the surface of the single piece and avoiding the problem of excessive core material on one side being squeezed out.
