Technical Field
[0001] This utility model relates to the field of demolding devices, and more particularly to a pneumatic demolding device for making gummy candies. Background Technology
[0002] Demolding is a crucial step in the gummy production process, referring to the removal of cooled and shaped gummies from the mold. This process requires both efficiency and maintaining the integrity and appearance of the gummies. Due to the stickiness and softness of gummies, problems such as sticking, deformation, or damage can easily occur during demolding.
[0003] The prior art (authorization announcement number CN203416780U) discloses a pneumatic demolding device for a gummy candy casting machine, and its instruction manual specifically discloses that "a high-pressure air pipe is installed on the side and rear of the ejector control rod." One end of the high-pressure air pipe is closed, and the other end is equipped with a valve. The other end of the valve is connected to a high-pressure air source. A row of air nozzles is installed on the high-pressure air pipe, and each air nozzle is directly facing a through hole at the bottom of a molding mold. Understandably, because the gummies adhere to the molding mold container during molding, and the gummies themselves have a certain degree of elasticity, when the ejector pin pushes into the through hole, some gummies cannot be ejected from the container, resulting in the gummies not being able to demold properly and the demolding effect being poor. To solve the problem of gummies not being able to demold properly, the existing technology uses a pneumatic mechanism, that is, a high-pressure air source, in conjunction with air nozzles for demolding. However, because the air nozzles are only set close to the through hole of the mold, the sealing between the air nozzles and the through hole of the mold is poor, and the airflow can easily leak from around the air nozzles, resulting in uneven airflow distribution. This will affect the demolding effect, which may result in the gummies not being able to completely detach from the mold, or the demolding time being too long, reducing production efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a pneumatic demolding device for gummies to solve the problems of existing technologies where the air nozzle is only located near the through-hole of the mold, resulting in poor sealing between the air nozzle and the through-hole. This allows airflow to easily leak from around the air nozzle, leading to uneven airflow distribution, which affects the demolding effect. This may result in the gummies not being completely removed from the mold, or excessive demolding time, leading to reduced production efficiency. The specific technical solution is as follows:
[0005] A pneumatic demolding device for forming soft candy is applied to a candy mold. The candy mold has a forming groove, and the bottom surface of the forming groove has an air inlet. The device includes a telescopic rod, an air compressor, and a cylinder. The first end of the telescopic rod is disposed in the air inlet, and the second end of the telescopic rod is connected to the cylinder. The end face of the first end of the telescopic rod has a groove, and a vent valve is installed at the opening of the groove. The air compressor is connected to the telescopic rod, and the air compressor delivers the generated compressed air to the groove.
[0006] As an improvement to the above technical solution, the air inlet includes a central inlet and several edge inlets. The central inlet is located at the center of the bottom surface of the forming groove, and the several edge inlets are arranged in a ring at equal intervals along the bottom edge of the forming groove.
[0007] As an improvement to the above technical solution, the end face of the first end of the telescopic rod is not higher than the bottom surface of the forming groove.
[0008] As an improvement to the above technical solution, the end face of the first end of the telescopic rod is flush with the bottom surface of the forming groove.
[0009] As an improvement to the above technical solution, the vent valve includes a cover plate, a spring, and a limiting plate. The cover plate is disposed at the opening of the groove and covers the groove. A support column is connected to the end face of the cover plate. The support column is disposed in the groove. The limiting plate is connected to the inner wall of the groove. The center of the limiting plate has an opening for receiving the support column. The support column passes through the limiting plate and its end is connected to a base plate. The spring is sleeved on the support column and is disposed between the limiting plate and the base plate.
[0010] As an improvement to the above technical solution, the limiting plate is provided with several through holes.
[0011] As an improvement to the above technical solution, an annular baffle is connected to the limiting plate, the annular baffle is arranged around the opening, and the spring is arranged in the annular baffle.
[0012] The beneficial effects of this invention are as follows: By starting the air compressor, the air compressor supplies gas to the groove inside the telescopic rod. When the gas in the groove reaches a certain level, the gas in the groove will be discharged out through the vent valve. The air compressor continues to supply gas, and the gas discharged through the vent valve will quickly fill the space. Continuing to supply gas will squeeze the candy out of the molding groove and complete the demolding. Since the telescopic rod is in the air inlet throughout the process, the airflow is not easy to leak, the sealing is guaranteed, and there is a better demolding effect.
[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Of course, implementing any product or method of this application does not necessarily require achieving all of the advantages described above at the same time. Attached Figure Description

[0019] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0020] Please see Figures 1-3 In this embodiment of the utility model, a pneumatic demolding device for gummy candy molding is provided to improve the efficiency and quality of demolding during candy production. It is particularly suitable for candy molds with molding grooves 1. Generally, the candy mold has an air inlet 11. The basic structure of the pneumatic demolding device includes a telescopic rod 2, an air compressor 3, a cylinder 5, and a specially designed air inlet 11 and a vent valve 4. It can effectively remove the gummy candy from the mold and avoid problems such as incomplete gummy candy shape that may occur with traditional demolding methods.
[0021] Specifically, an air inlet 11 is provided on the bottom surface of the forming groove 1, and the first end of the telescopic rod 2 is disposed in the air inlet 11. A groove 21 is provided on its end face to receive compressed air delivered by the air compressor 3. The second end of the telescopic rod 2 is connected to a cylinder 5, which is used to drive the telescopic rod 2 to extend and retract. The air compressor 3 is connected to the telescopic rod 2 through a pipe. When the device is running, the air compressor 3 delivers the generated compressed air to the groove 21, thereby generating airflow at the bottom of the forming groove 1 of the mold. Preferably, a flexible hose is connected between the telescopic rod 2 and the air compressor 3.
[0022] A vent valve 4 is installed at the opening of the groove 21. The function of the vent valve 4 is to release excess air under a specific pressure, which helps the gummy candy separate from the mold and allows the gummy candy to be demolded smoothly.
[0023] In the actual application of gummy candy demolding, cylinder 5 drives the movement of telescopic rod 2, causing the first end of telescopic rod 2 to extend and retract back and forth along the direction of air inlet 11. During this process, in order to ensure the integrity of the gummy candy in the molding groove 1, it is necessary to ensure that the end face of the first end of telescopic rod 2 is not higher than the bottom surface of molding groove 1. Preferably, the end face of the first end of telescopic rod 2 is usually flush with the bottom surface of molding groove 1. When it is necessary to demold the gummy candy, cylinder 5 will drive telescopic rod 2 to retract. At this time, the first end of telescopic rod 2 is still in the air inlet 11, and there is a space between the end face of the first end of telescopic rod 2 and the gummy candy. By starting air compressor 3, air compressor 3 delivers gas to groove 21 in telescopic rod 2. When the gas in groove 21 reaches a certain level, the gas in groove 21 will be discharged out through vent valve 4. Air compressor 3 continues to deliver gas. The gas discharged from vent valve 4 will quickly fill the space. Continuing to deliver gas can squeeze the gummy candy out of molding groove 1 and complete demolding.
[0024] Furthermore, this invention can also be applied to extruding hard candies. It is understood that, due to the presence of cylinder 5, cylinder 5 can directly drive telescopic rod 2 into molding groove 1, thereby helping the hard candy to be demolded. This technical solution can flexibly select the working mode as needed.
[0025] The vent valve 4, through an automatic control device, regulates the airflow to ensure that the air pressure does not become excessive during demolding, preventing the gummies from deforming or breaking due to excessive airflow. This device is compatible with existing gummy production lines, features high integration, and is easy to operate, while simultaneously improving the automation and efficiency of production, thus meeting the needs of large-scale gummy production.
[0026] This pneumatic demolding device significantly improves demolding efficiency, reduces manual intervention, lowers production costs, and enhances product quality consistency, making it an indispensable piece of equipment in modern gummy candy production.
[0027] Considering that the soft candy in the molding tank 1 is mainly adhered to the inner wall of the molding tank 1 around the perimeter, the air inlet 11 of the candy mold can be further improved. Specifically, the air inlet 11 includes a central inlet and several edge inlets. The central inlet is set at the center of the bottom surface of the molding tank 1, and the several edge inlets are arranged in a ring at equal intervals along the bottom edge of the molding tank 1.
[0028] The vent valve 4 includes a cover plate 41, a spring 45, and a limiting plate 43. The cover plate 41 is located at the opening of the groove 21 and covers the groove 21. A support column 42 is connected to the end face of the cover plate 41. The support column 42 is located inside the groove 21. The limiting plate 43 is connected to the inner wall of the groove 21. The center of the limiting plate 43 has an opening for receiving the support column 42. The support column 42 passes through the limiting plate 43 and its end is connected to a base plate 44. The spring 45 is sleeved on the support column 42 and is located between the limiting plate 43 and the base plate 44. The limiting plate 43 has several through holes 431. An annular baffle 432 is connected to the limiting plate 43 and surrounds the opening. The spring 45 is located in the annular baffle 432. The base plate 44 is limited by the annular baffle 432.
[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
