Description

Technical Field

[0001] The utility model relates to the technical field of food forming and processing, in particular to a food mould upper mould turning and resetting device. Background Art

[0002] In order to meet the preferences of different people for food shapes, food molds are becoming more and more diversified. The food mold demoulding production line improves the degree of automation in the food production process and is widely used in the production of hawthorn, biscuits and other foods.

[0003] The applicant in this case disclosed a molded food automated production line in the Chinese newly applied utility model patent applied for and authorized on April 1, 2024, with the authorization announcement number CN221996708U. In order to improve the efficiency of food demolding, the applicant in this case improved the molded food automated production line in the patent and designed a food mold synchronous demolding production line. The basic principle is to design a die-connecting station for transition between the mold stay station and the demolding station. When the flipping mechanism transfers the upper mold from the mold stay station to the die-connecting station, it can directly return to the next step without waiting. The upper mold on the die-connecting station is transferred to the demolding station for demolding by an upper mold conveying device, so that the demolding station and the mold stay station can operate synchronously, thereby improving the efficiency of food demolding.

[0004] When the upper mold is transported to the mold connection station, the lower mold continues to advance under the action of the mold conveyor, and the upper mold also continues to advance under the conveyor of the upper mold, and the two proceed synchronously. After the upper mold is demolded, it is necessary to re-fasten the upper mold on the lower mold downstream of the demolding station so that it can be refilled in the subsequent filling station. Therefore, it is necessary to design a reset device to merge the upper mold with the lower mold after demolding.

[0005] The design requirements of the reset device are: 1. It can stably and accurately transfer the upper mold to the position of the lower mold so that the upper mold and the lower mold are merged; 2. It has a simple structure and is easy to manufacture. Utility Model Content

[0006] The purpose of the utility model is to provide a food mold upper mold turning and resetting device which can stably and accurately merge the upper mold and the lower mold and has a simple structure and is easy to manufacture in order to solve the above problems.

[0007] The utility model is realized by using the following technical scheme: a food mold upper mold flipping and resetting device, comprising a first frame and a second frame, the second frame is equipped with a flipping frame for receiving the upper mold and driving the upper mold to flip to the lower mold, and the second frame is also equipped with a first driving mechanism for driving the flipping frame to rotate.

[0008] Through the above structure, the upper mold reaches the position of the flip frame after demolding. Driven by the first driving mechanism, the flip frame can stably and accurately flip the upper mold to the position of the lower mold and merge the two. This is achieved by the flip frame and the first driving mechanism, with a simple structure and easy manufacturing.

[0009] Furthermore, the first drive mechanism includes a motor fixedly mounted on the front side of the second frame, the output shaft of the motor being fixedly connected to a rotating shaft, both ends of the rotating shaft being rotatably engaged with the second frame, and the rotating shaft being fixedly connected to the flip frame. The cooperation between the motor and the rotating shaft enables the flip frame to perform stable flipping.

[0010] Furthermore, the flip frame includes a U-shaped frame fixedly mounted on the rotating shaft, with a bottom frame fixedly mounted at the bottom of the frame, and the frame opening faces right. The frame makes it easier for the upper mold to enter the flip frame, while the bottom frame supports the upper mold, making the flipping process more stable.

[0011] Furthermore, the frame opening is larger than the upper mold. When the upper mold is within the frame, a gap is left between the front and rear ends and the left side of the upper mold and the frame. The frame is also fixed with a limiting mechanism for positioning the upper mold within the frame. The gap between the frame and the upper mold allows the flip frame to better lower the upper mold when it rotates 180 degrees to the position of the lower mold. The setting of the limiting mechanism can prevent the upper mold from getting loose or even falling off during the flipping process due to the gap.

[0012] Furthermore, the limiting mechanism includes a second cylinder fixedly mounted on the inner side of the frame. The output end of the second cylinder is hingedly connected to one end of a connecting block, the other end of which is fixedly connected to a limiting plate. The second cylinder is also fixedly mounted to a fixing block, which is hingedly connected to a connecting plate. The top end of the connecting plate is hingedly connected to the middle of the connecting block. This structure allows the second cylinder to control the raising and lowering of the limiting plate, thereby achieving the release and locking of the upper mold.

[0013] Furthermore, there are four limiting mechanisms, and when the upper mold is located within the frame, the limiting mechanisms correspond to the four corners of the upper mold. By setting the four limiting mechanisms, the upper mold can be more stable when it is driven by the turning frame to turn over.

[0014] Furthermore, the front and rear sides of the first frame are both equipped with lifting plates that can be driven by the second driving mechanism to slide up and down, and the front and rear ends of the upper mold can be overlapped on the lifting plates. Through the arrangement of the lifting plates, the upper mold can fall on the lower mold more stably.

[0015] Furthermore, the first frame is provided with lifting openings on both sides, and the second drive mechanism includes a first cylinder fixedly mounted on the first frame, the output end of the first cylinder being fixedly connected to a connecting beam, the ends of which are respectively fixedly connected to the bottom ends of the two lifting plates, and the connecting beams slidingly engage with the lifting openings. The arrangement of the connecting beams and the first cylinder enables the two lifting plates to move up and down synchronously.

[0016] Furthermore, the lower mold is equipped with right-angled grooves at both its front and rear ends. The top ends of the two lifting plates extend inward to form receiving plates, which are located at the right-angled grooves and have a thickness equal to the depth of the right-angled grooves. The provision of the receiving plates ensures greater stability when the upper mold is attached to the lifting plates, while the provision of the right-angled grooves prevents the receiving plates from interfering with the merging of the upper and lower molds.

[0017] Furthermore, a buffer block is fixedly mounted on the second frame, and the end of the frame away from the motor can be overlapped on the buffer block. By setting the buffer block, the turning frame can be limited and shock-absorbing, thereby increasing the stability of the device.

[0018] In summary, the beneficial effects of the present invention are:

[0019] Through the setting of the turning frame and the lifting plate, the turning frame drives the upper mold to turn over, so that the upper mold falls on the lifting plate, and then the turning frame returns, and the lifting plate falls until the upper mold and the lower mold are merged, thereby making the upper mold able to be more stably and accurately merged with the lower mold. At the same time, the structure of this device is simple, the manufacturing is convenient, and it is suitable for mass production. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] In the description of this application, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.

[0027] The following is a description of preferred embodiments of the present invention with reference to the accompanying drawings.

[0028] like Figures 1 to 3 As shown, the present invention provides a food mold upper mold flipping and resetting device, comprising a first frame 1 and a second frame 2. The first frame 1 is provided with a mold conveying device 4 for conveying the mold, and the second frame 2 is provided with a tray conveying device for conveying the material tray. A flip frame, which can be driven to rotate by a first drive mechanism, is also mounted on the second frame 2. The right side and top of the flip frame are open. The right side of the flip frame is open to allow the upper mold 7 to enter the flip frame from the right side, and the top of the flip frame is open to allow the upper mold 7 to cover the lower mold 11 from this location. The flip frame can drive the upper mold 7 in the flip frame to transfer to the lower mold 11 on the first frame 1. The mold conveying device 4, the tray conveying device 3, the material tray, the upper mold 7, and the lower mold 11 are all prior art. For details, please refer to the newly applied Chinese utility model patent application, "An Automated Production Line for Molded Food," with authorization announcement number CN221996708U.

[0029] The first driving mechanism mentioned above can be any mechanism that can drive the flip frame to rotate. In this embodiment, the first driving mechanism includes a motor 9 fixedly installed on the front side of the second frame 2, and the output shaft of the motor 9 is fixedly connected to the rotating shaft 10. The two ends of the rotating shaft 10 are rotatably matched with the second frame 2, and the rotating shaft 10 is fixedly connected to the flip frame.

[0030] The flip frame includes a U-shaped frame 6 fixedly mounted on the rotating shaft 10, and a base frame 18 is fixedly mounted on the bottom of the frame 6, with the opening of the frame 6 facing right. The base frame 18 is provided so that the flip frame provides support for the upper mold 7 when driving the upper mold 7 to rotate.

[0031] As a further illustration of this example, the size of the opening of the frame 6 is larger than that of the upper mold 7, that is, when the upper mold 7 is in the frame 6, there is a gap between the front and rear ends and the left side of the upper mold 7 and the frame 6. Through this gap, when the flip frame is covered on the top of the lower mold 11, the upper mold 7 can be better separated from the flip frame, so that the upper mold 7 falls on the lower mold 11 and merges with it. In order to prevent the upper mold 7 from deviating or detaching from the flip frame when the flip frame drives the upper mold 7 to flip due to the existence of the gap, a limiting mechanism 8 is fixedly installed on the frame 6 for positioning the upper mold 7 in the frame 6.

[0032] like Figure 3 、 Figure 4 As shown, the limiting mechanism 8 includes a second cylinder 19 fixedly mounted on the inner side of the frame 6. The output end of the second cylinder 19 is hingedly connected to one end of a connecting block 20, the other end of which is fixedly connected to a limiting plate 22. A fixing block 23 is also fixedly mounted on the second cylinder 19, and a connecting plate 21 is hingedly connected to the fixing block 23. The top end of the connecting plate 21 is hingedly connected to the middle of the connecting block 20. When the output shaft of the second cylinder 19 is extended, the limiting plate 22 presses down on the upper mold 7. When the output end of the second cylinder 19 is retracted, the limiting plate 22 is lifted upward, thereby not affecting the upper mold 7 from separating from the flip frame.

[0033] As a further illustration of this example, in order to stably limit the upper mold 7 in the flip frame, four limiting mechanisms 8 are provided. When the upper mold 7 is located in the frame 6, the limiting mechanisms 8 correspond to the four corners of the upper mold 7.

[0034] like Figure 1 、 Figure 2 As shown, both the front and rear sides of the first frame 1 are equipped with lifting plates 12 that can be driven by the second driving mechanism to slide up and down, and the front and rear ends of the upper mold 7 can be overlapped on the lifting plates 12.

[0035] Since the height of the turning frame is higher than the lower mold 11 on the first frame 1 when the turning frame is placed horizontally on the second frame 2, there is a certain distance between the upper mold 7 and the lower mold 11 after the turning frame is turned 180 degrees. If the upper mold 7 is directly released at this time, the upper mold 7 will fall freely onto the lower mold 11. This method makes the merging of the upper mold 7 and the lower mold 11 unstable. Therefore, a lifting plate 12 is provided to solve this problem.

[0036] Specifically, lift openings 15 are provided on both sides of the first frame 1. The second drive mechanism includes a first cylinder 17 fixedly mounted on the first frame 1. The output end of the first cylinder 17 is fixedly connected to a connecting beam 16. The ends of the connecting beam 16 are respectively fixedly connected to the bottom ends of the two lift plates 12. The connecting beam 16 slidably engages with the lift openings 15. The first cylinder 17 drives the middle portion of the connecting beam 16. Alternatively, multiple first cylinders 17 can be provided to drive the connecting beam 16 up and down, thereby achieving synchronous up and down movement of the two lift plates 12.

[0037] As a further illustration of this embodiment, right-angled grooves 13 are provided at both the front and rear ends of the lower mold 11. The top ends of the two lifting plates 12 extend inward to form receiving plates 14. The receiving plates 14 are located at the right-angled grooves 13, and the thickness of the receiving plates 14 is the same as the depth of the right-angled grooves 13. The provision of the receiving plates 14 makes the upper mold 7 more stable when it is overlapped on the lifting plates 12, while the provision of the right-angled grooves 13 prevents the receiving plates 14 from affecting the merging of the upper mold 7 and the lower mold 11.

[0038] As a further illustration of this example, a buffer block 5 is fixedly mounted on the second frame 2, and the end of the frame 6 away from the motor 9 can be overlapped on the buffer block 5. When the turning frame is placed flat on the second frame 2, the buffer block 5 provides a support for the rear end of the turning frame.

[0039] The operating principle of this device is as follows: first, the upper mold 7 enters the interior of the turning frame under the drive of the conveying device. When it reaches the specified position, the second cylinder 19 starts to lock the upper mold 7 on the turning frame, and then the motor 9 starts to drive the turning frame to turn over. During the turning process of the turning frame, the first cylinder 17 is also started at the same time, driving the lifting plate 12 to rise. When the two ends of the upper mold 7 on the turning frame contact the top surface of the lifting plate 12, the output end of the second cylinder 19 is retracted, so that the upper mold 7 is overlapped on the lifting plate 12, and then the turning frame returns to the second frame 2 under the drive of the motor 9. At the same time, the first cylinder 17 drives the lifting plate 12 to fall, so that the upper mold 7 falls smoothly on the lower mold 11. The upper mold 7 and the lower mold 11 are merged together by magnetic attraction, and then continue to move to the right for seasoning under the drive of the mold conveying device.

[0040] To sum up, the present invention provides a food mold upper mold flipping and resetting device. Through the setting of the flip frame and the lifting plate 12, the flip frame drives the upper mold 7 to flip, so that the upper mold 7 falls on the lifting plate 12, and then the flip frame returns, and the lifting plate 12 falls until the upper mold 7 is merged with the lower mold 11, thereby enabling the upper mold 7 to be more stably and accurately merged with the lower mold 11. At the same time, the structure of the device is simple, the manufacturing is convenient, and it is suitable for mass production.

[0041] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
