[0001] This invention relates to the field of food machinery technology, specifically to a crystal bag forming device and its forming process. Background Technology

[0002] Crystal dumplings are a common snack, prized for their pure white color, soft texture, attractive appearance, and delicious taste. They have gained popularity in recent years, resulting in high market demand. While crystal dumplings come in various shapes on the market, the most popular are those resembling flowers. However, these flower-shaped dumplings are typically handmade, and traditional handmade production methods, due to their slow speed, lack of hygiene, and difficulty in controlling specifications, can no longer meet market demands.

[0003] In view of this, the inventors of this case conducted in-depth research on the above-mentioned problems, which led to the creation of this case. Summary of the Invention

[0004] The first objective of this invention is to address the above-mentioned shortcomings by providing a crystal bag forming device that can quickly form flower-shaped crystal bags with high efficiency and uniform quality.

[0005] The first solution adopted by the present invention to solve the technical problem is: a crystal bag forming device, including a frame, a forming mold mounted on the frame, and a mold opening and closing mechanism. The forming mold includes a circular lower mold for placing crystal skin and several petal molds rotatably mounted on the lower mold. The petal molds are arranged around the outer periphery of the lower mold. The upper side of the lower mold is a concave arc surface. The petal molds are provided with forming cavities with openings facing the lower mold. The lower cavity surface of the forming cavity is connected to the upper side surface of the lower mold to form the crystal bag body. A gap is provided between the inner sides of two adjacent petal molds to form crystal bag pleats. The mold opening and closing mechanism is connected to the petal molds to drive the petal molds to rotate relative to the lower mold to open and close the mold. The crystal bag forming device also includes a pinching mechanism for pinching the lower side of the crystal bag pleats to the crystal bag body.

[0006] Furthermore, in order to form the main body of the crystal bag, the petal mold has a fan-shaped structure, and the forming inner cavity includes an arc-shaped lower cavity that is radially recessed from the lower side of the petal mold and a sealing part provided on the upper side of the petal mold for sealing the crystal bag. The lower cavity surface of the arc-shaped lower cavity is connected to the upper side surface of the lower mold, and the distance between the sealing part and the central axis of the lower mold is less than the thickness of the crystal skin to ensure that the crystal bag is sealed.

[0007] Furthermore, in order to form the crystal pleats, the outer sides of two adjacent pleats are connected, and the inner sides of two adjacent pleats are recessed inward to form a gap for forming the crystal pleats. The width of the gap is less than the sum of the thicknesses of the two crystal layers to ensure that the crystal pleats adhere.

[0008] Furthermore, in order to rotatably mount the petal mold onto the lower mold, the molding die also includes a lower template. The lower mold is provided with a connecting shaft extending axially downward. The connecting shaft is mounted on the lower template. The connecting shaft is provided with a hinge arm extending obliquely upward. The lower side of the petal mold is provided with a hinge plate. The inner side of the hinge plate is hinged to the hinge arm, thereby rotatably mounting the petal mold onto the lower mold.

[0009] Furthermore, in order to drive the petal mold to rotate and open / close the mold, the mold opening / closing mechanism includes a sliding sleeve and a mold opening / closing cylinder. The sliding sleeve is movably sleeved on the connecting shaft. An upper connecting rod is hinged to the outer side of the hinge plate. A lower connecting rod is hinged to the lower end of the upper connecting rod. The lower end of the lower connecting rod is hinged to the sliding sleeve so that the petal mold can rotate relative to the lower mold to open / close the mold through the up and down movement of the sliding sleeve.

[0010] The mold opening and closing cylinder is mounted on the machine frame. Several guide rods are provided on the lower side of the sliding sleeve. The lower end of the guide rod moves through the lower template and is connected to a drive plate. The drive plate is mounted on the cylinder rod of the mold opening and closing cylinder so that the mold opening and closing cylinder can drive the sliding sleeve to slide up and down, thereby driving the petal mold to rotate relative to the lower mold to open and close the mold.

[0011] Furthermore, in order to pinch the lower side of the crystal bag pleats together with the crystal bag body, the crystal bag pleats are pinched into a petal shape; the upper side of the frame is provided with a worktable, and the pinching mechanism includes a mounting frame, a silicone pinching head for pressing against the outer side of the lower part of the crystal bag pleats, a drive component for driving the silicone pinching head to move towards the crystal bag body, a turntable on the worktable, and a turntable motor for driving the turntable to rotate. The drive component is mounted on the mounting frame, the silicone pinching head is mounted on the drive component, and the molding mold and the mold opening and closing mechanism are both mounted on the turntable so that when the drive component drives the silicone pinching head to move towards the crystal bag body, the turntable drives the crystal bag body to rotate and cooperate with the silicone pinching head to pinch the lower side of the crystal bag pleats together with the crystal bag body.

[0012] Furthermore, in order to drive the silicone kneading head to move downward to the mold, causing the lower side of the crystal bag pleats to bend towards the crystal bag body; the driving assembly includes a driver, a fixed plate and a rotating ring, the driver and the fixed plate are both mounted on the mounting bracket and the fixed plate is located next to the driver, the rotating ring is rotatably mounted on the fixed plate, and the driver is connected to the rotating ring in a transmission connection to drive the rotating ring to rotate;

[0013] The fixed plate has several T-shaped grooves radially arranged, and a slider is slidably installed in the T-shaped groove. The rotating ring has several arc-shaped guide grooves corresponding to the T-shaped grooves. The slider has a sliding rod that moves downward through the arc-shaped guide groove. The silicone pinch head is installed at the bottom of the sliding rod so that the rotation of the rotating ring drives the silicone pinch head to move radially to pinch the lower side of the crystal bag pleats together with the crystal bag body.

[0014] Furthermore, in order to drive the rotating ring to rotate, and thus drive the slider to slide radially, the driver is a servo motor, which is mounted on a mounting bracket. A drive gear is coaxially fixed on the motor shaft of the servo motor. A toothed ring is provided on the outer circumference of the rotating ring. The drive gear meshes with the toothed ring to drive the rotating ring to rotate.

[0015] Furthermore, to prevent the upper part of the crystal bag pleats from sticking to the main body of the crystal bag, the pleating mechanism also includes a turntable, several silicone pressure heads for pressing against the inside of the crystal bag pleats to prevent the upper part of the crystal bag pleats from sticking to the main body of the crystal bag, and a lifting cylinder for driving the silicone pressure heads to move up and down. The lifting cylinder is mounted on a mounting frame, and the cylinder rod of the lifting cylinder passes through the mounting frame and is connected to the turntable. The turntable is rotatably mounted on a fixed plate through bearings. The rotating ring has a through hole in the middle, and the turntable has several pressure rods that move downward through the through hole of the rotating ring. The silicone pressure heads are mounted on the bottom of the pressure rods.

[0016] The second objective of this invention is to address the above-mentioned shortcomings by providing a crystal bag forming device that can quickly form flower-shaped crystal bags with high efficiency and uniform quality.

[0017] The second solution adopted by the present invention to solve the technical problem is: a process for forming crystal bags using a crystal bag forming device, comprising the following steps:

[0018] (1) Place the crystal skin on the lower mold, inject the filling into the crystal skin, and then drive the petal mold to rotate relative to the lower mold by the opening and closing mold mechanism, so that the crystal skin can wrap the filling to form the main body of the crystal bag. At the same time, the crystal bag pleats are formed.

[0019] (2) The lifting cylinder drives the fixed plate to move down, causing the silicone pressure head to press against the inner side of the upper part of the crystal pleats. At the same time, the silicone pinching head moves to the outer side of the lower part of the crystal pleats.

[0020] (3) The turntable motor drives the turntable to rotate at a small angle, which causes the main body of the crystal bag to rotate slightly. The silicone pressure head rotates slightly with the main body of the crystal bag. At the same time, the servo motor drives the rotating ring to rotate, and the slide rod slides along the slide groove, which causes the silicone kneading head to move radially, gradually kneading the lower side of the crystal bag pleats with the main body of the crystal bag, and kneading the crystal bag pleats into a petal shape.

[0021] (4) After kneading and shaping, the servo motor drives the rotating ring to reverse, the silicone kneading head moves away from the main body of the crystal bag, the lifting cylinder contracts, and the silicone pressing head moves away from the main body of the crystal bag, thus completing the shaping of the crystal bag.

[0022] Compared with the prior art, the present invention has the following advantages:

[0023] (1) The present invention uses a mold to automatically form crystal bags. When in use, the crystal skin is placed on the lower mold, the filling is poured into the crystal skin, and the sliding sleeve is driven by the mold opening and closing cylinder to slide upward, causing the petal mold to rotate and close relative to the lower mold, causing the crystal skin to close and cover the filling. The arc-shaped lower cavity can form the main body of the crystal bag, the sealing part can seal the crystal bag, and the gap can form the crystal bag pleats. After the crystal bag is formed, the sliding sleeve is driven by the mold opening and closing cylinder to slide downward, causing the petal mold to rotate and open relative to the lower mold, thus completing the mold opening of the crystal bag. At this time, the crystal bag on the lower mold can be taken out to continue the production of the next crystal bag.

[0024] (2) This invention forms a crystal bag with five corners by creating five gaps in the molding mold, making the crystal bag look like a flower. It is beautiful in appearance, and has high production efficiency and stable quality. The crystal bag with five corners can be directly put into the market for sale. Alternatively, it can be further pleated by machine or by hand, pinching the bottom of the five corners of the crystal bag to the side to make the pleats into petal shape, symbolizing wealth and prosperity, and then put into the market for sale.

[0025] (3) By setting up a flower-pinching mechanism, the five corners of the crystal bag can be further bent into petal shapes. Specifically, after the molding mold is opened, the lifting cylinder drives the fixed plate to move down, which drives the silicone pressure head to press against the inner side of the upper part of the crystal bag pleats. At the same time, it drives the silicone pinching head to move to the outer side of the lower part of the crystal bag pleats. The servo motor drives the rotating ring to rotate, and the guide rod slides radially along the slide groove, which drives the silicone pinching head to move radially, gradually pinching the lower side of the crystal bag pleats with the crystal bag body, pinching the crystal bag pleats into petal shapes. After the shape is formed, the servo motor drives the rotating ring to reverse, the silicone pinching head moves away from the crystal bag body, the lifting cylinder contracts, and the silicone pressure head moves away from the crystal bag body, thus forming a petal-shaped crystal bag.

[0037] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0038] Example 1: As Figure 1-9 As shown, a crystal bag forming device includes a frame, a forming mold 1 mounted on the frame, and a mold opening and closing mechanism 2. The forming mold 1 includes a circular lower mold 11 for placing crystal skin and several petal molds 12 rotatably mounted on the lower mold 11. The petal molds 12 are arranged around the outer periphery of the lower mold 11. The upper side of the lower mold 11 is a concave arc surface. The petal molds 12 have forming cavities with openings facing the lower mold 11. The lower cavity surface of the forming cavity is connected to the upper side surface of the lower mold 11 to form the crystal bag body 4. A gap 124 is provided between the inner sides of two adjacent petal molds 12 to form crystal bag pleats 5. The mold opening and closing mechanism 2 is connected to the petal molds 12 to drive the petal molds 12 to rotate relative to the lower mold 11 to open and close the mold. The crystal bag forming device also includes a pinching mechanism 3 for pinching the lower side of the crystal bag pleats 5 to the crystal bag body 4.

[0039] In this embodiment, in order to form the crystal bag body 4, the petal mold 12 has a fan-shaped structure, and the forming inner cavity includes an arc-shaped lower cavity 121 that is radially recessed from the lower side of the petal mold 12 and a sealing part 122 provided on the upper side of the petal mold 12 for sealing the crystal bag. The lower cavity surface of the arc-shaped lower cavity 121 is connected to the upper side surface of the lower mold 11, and the distance between the sealing part 122 and the central axis of the lower mold 11 is less than the thickness of the crystal skin to ensure that the crystal bag is sealed.

[0040] In this embodiment, in order to form the crystal pleated piece 5, the outer sides of two adjacent petal molds 12 are connected, and the inner sides of the two adjacent petal molds 12 are recessed inward to form a gap 124 for forming the crystal pleated piece 5. The width of the gap 124 is less than the sum of the thicknesses of the two crystal skins to ensure that the crystal pleated piece 5 is adhered.

[0041] In this embodiment, in order to rotatably mount the petal mold 12 onto the lower mold 11, the molding die 1 further includes a lower template 25, which is mounted on the frame via a support frame 26. The lower mold 11 is provided with a connecting shaft 111 extending axially downward, which is mounted on the lower template 25. The connecting shaft 111 is provided with a hinge arm 125 extending obliquely upward. The lower side of the petal mold 12 is provided with a hinge plate 123, and the inner side of the hinge plate 123 is hinged to the hinge arm 125, thereby rotatably mounting the petal mold 12 onto the lower mold 11.

[0042] In this embodiment, in order to drive the petal mold 12 to rotate and open / close the mold, the mold opening and closing mechanism 2 includes a sliding sleeve 21 and a mold opening and closing cylinder 24. The sliding sleeve 21 is movably sleeved on the connecting shaft 111. The outer side of the hinge plate 123 is hinged to an upper connecting rod 22. The lower end of the upper connecting rod 22 is hinged to a lower connecting rod 23. The lower end of the lower connecting rod 23 is hinged to the sliding sleeve 21 so that the petal mold 12 can be driven to rotate relative to the lower mold 11 to open and close the mold through the up and down movement of the sliding sleeve 21.

[0043] The mold opening and closing cylinder 24 is mounted on the machine frame. Several guide rods 28 are provided on the lower side of the sliding sleeve 21. The lower end of the guide rod 28 moves through the lower template 25 and is connected to the drive plate 27. The drive plate 27 is mounted on the cylinder rod of the mold opening and closing cylinder 24 so that the mold opening and closing cylinder 24 can drive the sliding sleeve 21 to slide up and down, thereby driving the petal mold 12 to rotate relative to the lower mold 11 to open and close the mold.

[0044] In this embodiment, in order to pinch the lower side of the crystal bag pleat 5 together with the crystal bag body 4, the crystal bag pleat 5 is pinched into a petal shape; the upper side of the frame is provided with a worktable, and the pinching mechanism 3 includes a mounting frame 32, a silicone pinching head 31 for pressing against the lower outer side of the crystal bag pleat 5, a drive component for driving the silicone pinching head 31 to move closer to the crystal bag body 4, a turntable on the worktable, and a turntable motor for driving the turntable to rotate. The drive component is mounted on the mounting frame 32, the silicone pinching head 31 is mounted on the drive component, and the molding mold 1 and the mold opening and closing mechanism 2 are both mounted on the turntable so that when the drive component drives the silicone pinching head 31 to move closer to the crystal bag body 4, the turntable drives the crystal bag body 4 to rotate and cooperate with the silicone pinching head 31 to pinch the lower side of the crystal bag pleat 5 together with the crystal bag body 4.

[0045] In this embodiment, in order to drive the silicone kneading head 31 to move downward to the mold 11, causing the lower side of the crystal bag pleat 5 to bend towards the crystal bag body 4; the driving assembly includes a driver, a fixed plate 34 and a rotating ring 35. The driver and the fixed plate 34 are both mounted on the mounting bracket 32 ​​and the fixed plate 34 is located next to the driver. The rotating ring 35 is rotatably mounted on the fixed plate 34, and the driver is connected to the rotating ring 35 in a transmission connection to drive the rotating ring 35 to rotate.

[0046] The fixed plate 34 has several T-shaped grooves 341 radially arranged, and a slider 312 is slidably installed in the T-shaped grooves 341. The rotating ring 35 has several arc-shaped guide grooves 351 corresponding to the T-shaped grooves 341. The slider 312 has a sliding rod 311 that moves downward through the arc-shaped guide grooves 351. The silicone pinching head 31 is installed at the bottom of the sliding rod 311 so that the rotation of the rotating ring 35 drives the silicone pinching head 31 to move radially and pinch the lower side of the crystal bag pleats 5 and the crystal bag body 4 together. Here, the rotation of the slider can be slow or it can be gradually and repeatedly rotated, that is, rotate once and reset, rotate again and reset again, and the angle of each rotation gradually increases to simulate the pinching effect.

[0047] In this embodiment, in order to drive the rotating ring 35 to rotate, and thus drive the slider 312 to slide radially, the driver is a servo motor 36, which is mounted on the mounting bracket 32. The servo motor 36 has a drive gear 37 coaxially fixedly mounted on the motor shaft of the servo motor 36. The outer periphery of the rotating ring 35 is provided with a toothed ring, and the drive gear 37 meshes with the toothed ring to drive the rotating ring 35 to rotate.

[0048] In this embodiment, to prevent the upper part of the crystal bag pleat 5 from sticking to the crystal bag body 4, the pinching mechanism 3 also includes a turntable, several silicone pressure heads 38 for pressing against the inside of the crystal bag pleat 5 to prevent the upper part of the crystal bag pleat 5 from sticking to the crystal bag body 4, and a lifting cylinder 33 for driving the silicone pressure heads 38 to move up and down. The lifting cylinder 33 is mounted on the mounting frame 32. The cylinder rod of the lifting cylinder 33 passes through the mounting frame 32 and is connected to the turntable. The turntable is rotatably mounted on the fixed plate 34 through the bearing. The rotating ring 35 has a through hole in the middle. The turntable has several pressure rods 381 that move downward through the through hole of the rotating ring 35. The silicone pressure heads 38 are mounted on the bottom of the pressure rods 381.

[0049] In this embodiment, to further improve the flower-pinching effect, the present invention can also be equipped with a lifting mechanism that drives the turntable to rise and fall. While the turntable rotates, it is driven to fall, bending the crystal bag pleats 5 inward and upward toward the crystal bag body 4, making the crystal bag pleats 5 more aesthetically pleasing. Specifically, by setting a lifting cylinder, a lifting plate is installed on the cylinder rod of the lifting cylinder, the turntable motor is installed on the lifting plate, and the turntable is installed on the turntable motor, so that when pinching flowers, the crystal bag body 4 rotates itself and moves downward at the same time, cooperating with the pinching silicone head to move radially inward, thereby bending the crystal bag pleats 5 upward and inward, pinching the crystal bag pleats 5 into a petal shape.

[0050] Example 2: A process for forming crystal bags using a crystal bag forming device, comprising the following steps:

[0051] (1) Place the crystal skin on the lower mold 11, inject the filling into the crystal skin, and then drive the petal mold 12 to rotate relative to the lower mold 11 by the opening and closing mold mechanism 2, so that the crystal skin can wrap the filling to form the crystal bag body 4, and at the same time, the crystal bag pleats 5 are formed.

[0052] (2) The lifting cylinder 33 drives the fixed plate 34 to move down, which drives the silicone pressure head 38 to press against the inner side of the upper part of the crystal pleated 5. At the same time, the silicone pinching head 31 moves to the outer side of the lower part of the crystal pleated 5.

[0053] (3) The turntable motor drives the turntable to rotate at a small angle, which causes the crystal bag body 4 to rotate slightly. The silicone pressure head 38 rotates slightly with the crystal bag body 4. At the same time, the servo motor 36 drives the rotating ring 35 to rotate. The slide rod 311 slides along the slide groove, which drives the silicone pinching head 31 to move radially, gradually pinching the lower side of the crystal bag pleat 5 with the crystal bag body 4, and pinching the crystal bag pleat 5 into a petal shape.

[0054] (4) After kneading and shaping, the servo motor 36 drives the rotating ring 35 to reverse, the silicone kneading head 31 moves away from the crystal bag body 4, the lifting cylinder 33 retracts, and drives the silicone pressing head 38 away from the crystal bag body 4, thus completing the shaping of the crystal bag.

[0055] This invention uses an automatic mold to form crystal bags. In use, the crystal skin is placed on the lower mold 11, and the filling is poured onto the crystal skin. The opening and closing cylinder 24 drives the sliding sleeve 21 to slide upward, causing the petal mold 12 to rotate and close relative to the lower mold 11, thus closing the crystal skin to cover the filling. The arc-shaped lower cavity 121 can form the crystal bag body 4, the sealing part 122 can seal the crystal bag, and the gap 124 can form the crystal bag pleats 5. After the crystal bag is formed, the opening and closing cylinder 24 drives the sliding sleeve 21 to slide downward, causing the petal mold 12 to rotate and open relative to the lower mold 11, thus completing the mold opening of the crystal bag. At this time, the crystal bag on the lower mold 11 can be taken out to continue the production of the next crystal bag.

[0056] This invention creates a crystal bag with five corners by forming five gaps 124 in the molding mold 1, making the crystal bag look like a flower. It is aesthetically pleasing, has high production efficiency, and stable quality. The crystal bag with five corners can be directly put on the market for sale, or it can be further pleated mechanically or manually by pinching the bottom of the five corners of the crystal bag to the side to form a petal shape, symbolizing wealth and prosperity, before being put on the market for sale.

[0057] This invention, by setting a flower-pinching mechanism 3, can further bend the five corners of the crystal bag into petal shapes. Specifically, after the molding mold 1 is opened, the lifting cylinder 33 drives the fixed plate 34 to move down, causing the silicone pressing head 38 to press against the upper inner side of the crystal bag pleats 5. At the same time, it drives the silicone pinching head 31 to move to the lower outer side of the crystal bag pleats 5. The servo motor 36 drives the rotating ring 35 to rotate, and the slide rod 311 slides radially along the slide groove, causing the silicone pinching head 31 to move radially, gradually pinching the lower side of the crystal bag pleats 5 with the crystal bag body 4, pinching the crystal bag pleats 5 into a petal shape. After the shape is formed, the servo motor 36 drives the rotating ring 35 to reverse, the silicone pinching head 31 moves away from the crystal bag body 4, the lifting cylinder 33 retracts, and the silicone pressing head 38 moves away from the crystal bag body 4, thus forming a petal-shaped crystal bag.

The lower side of the petal mold has a hinge plate. The inner side of the hinge plate is hinged to the hinge arm, thereby rotating the petal mold onto the lower mold.

5. The crystal packaging forming apparatus according to claim 4, characterized in that: The mold opening and closing mechanism includes a sliding sleeve and a mold opening and closing cylinder. The sliding sleeve is movably sleeved on the connecting shaft. An upper connecting rod is hinged to the outer side of the hinge plate. A lower connecting rod is hinged to the lower end of the upper connecting rod. The lower end of the lower connecting rod is hinged to the sliding sleeve so that the up and down movement of the sliding sleeve can drive the petal mold to rotate relative to the lower mold to open and close the mold. The mold opening and closing cylinder is mounted on the machine frame. Several guide rods are provided on the lower side of the sliding sleeve. The lower end of the guide rod moves through the lower template and is connected to a drive plate. The drive plate is mounted on the cylinder rod of the mold opening and closing cylinder so that the mold opening and closing cylinder can drive the sliding sleeve to slide up and down, thereby driving the petal mold to rotate relative to the lower mold to open and close the mold.

6. A process for forming crystal bags using the crystal bag forming apparatus according to any one of claims 1-5, characterized in that: Includes the following steps: (1) Place the crystal skin on the lower mold, inject the filling into the crystal skin, and then drive the petal mold to rotate relative to the lower mold by the opening and closing mold mechanism, so that the crystal skin can wrap the filling to form the main body of the crystal bag. At the same time, the crystal bag pleats are formed. (2) The lifting cylinder drives the fixed plate to move down, causing the silicone pressure head to press against the inner side of the upper part of the crystal pleats. At the same time, the silicone pinching head moves to the outer side of the lower part of the crystal pleats. (3) The turntable motor drives the turntable to rotate at a small angle, which causes the main body of the crystal bag to rotate slightly. The silicone pressure head rotates slightly with the main body of the crystal bag. At the same time, the servo motor drives the rotating ring to rotate, and the slide rod slides along the slide groove, which causes the silicone kneading head to move radially, gradually kneading the lower side of the crystal bag pleats with the main body of the crystal bag, and kneading the crystal bag pleats into a petal shape. (4) After kneading and shaping, the servo motor drives the rotating ring to reverse, the silicone kneading head moves away from the main body of the crystal bag, the lifting cylinder contracts, and the silicone pressing head moves away from the main body of the crystal bag, thus completing the shaping of the crystal bag.
