[0002] As people's living standards improve, quick-frozen food is becoming more and more popular among consumers due to its convenience and speed. Among them, quick-frozen glutinous rice balls, as a traditional festival food, are widely demanded in the market. In order to meet the market's requirements for packaging efficiency and quality of quick-frozen glutinous rice balls, automatic bagging machines have gradually become one of the indispensable equipment for production enterprises.

[0003] In the existing automatic bagging process of quick-frozen glutinous rice balls, a tray is usually used to separate and place the glutinous rice balls to avoid damage or adhesion during the packaging process. However, the existing technology has certain limitations: when the glutinous rice balls enter the tray through the feeding device, due to mechanical vibration or the irregular shape of the glutinous rice balls themselves, the glutinous rice balls may not fall accurately into the designated grooves in the tray, or there may be too much or too little material in a single groove. These problems not only affect the appearance quality of the product, but may also cause waste of resources and increase production costs. In order to solve this problem, in the actual packaging process, manual intervention is required to fill in the gaps or re-place the glutinous rice balls that are not placed correctly, but this obviously increases labor costs.

[0004] In order to solve the above problems, we propose an automatic bagging machine for quick-frozen glutinous rice balls and a method thereof, which can automatically adjust the position of glutinous rice balls that are not accurately placed in the grooves of the tray to ensure that the glutinous rice balls are neatly placed.

DETAILED DESCRIPTION

[0036] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Embodiment 1: A quick-frozen glutinous rice balls automatic bagging machine, such as Figure 1-Figure 10As shown, it includes an installation frame 1, a first conveying group 2, a placement frame 3, a first electric push rod 4, a first baffle 41, a fixed frame 51, a push plate 52, a hinge frame 53, a torsion spring 530, a second electric push rod 531, a contact frame 532, a cam 533, a tray 54, a second conveying member 55, a packaging structure 551, a push assembly and a sorting assembly. The first conveying group 2 is installed in the installation frame 1, and the conveyor belt of the first conveying group 2 is provided with equidistantly distributed convex strips. The left side of the installation frame 1 The upper part is fixedly connected with a placing frame 3, and five equally spaced partition plates are fixedly arranged at the lower part of the placing frame 3, which are used to divide the placing frame 3 into six independent channels for unloading the glutinous rice balls. The front side of the placing frame 3 is fixedly connected with a first electric push rod 4, and the lower part of the placing frame 3 is slidably connected with a first baffle 41, and the first baffle 41 is fixedly connected to the telescopic end of the first electric push rod 4. The lower side of the placing frame 3 is fixedly connected with a fixed frame 51, and six compartments are arranged in the fixed frame 51, which correspond to the unloading channels of the placing frame 3 one by one. The fixed frame 51 A push plate 52 is fixedly connected to the lower right part, three equally spaced articulated frames 53 are rotatably connected to the lower side of the fixed frame 51, eighteen equally spaced feed openings are opened on the lower side of the fixed frame 51, and six equally spaced opening and closing plates are arranged on the articulated frames 53 to block the adjacent feed openings. A torsion spring 530 is connected between the articulated frame 53 and the fixed frame 51, a second electric push rod 531 is fixedly connected to the front side of the fixed frame 51, and a contact frame 532 is fixedly connected to the telescopic end of the second electric push rod 531. A cam 533 is fixedly connected to the front of the frame 53, and the contact frame 532 moves downward to be squeezed and matched with the cam 533. Equidistantly distributed trays 54 are placed on the first conveying group 2, and a second conveying member 55 is installed on the right front side of the mounting frame 1. A packaging structure 551 is fixedly connected to the right front side of the mounting frame 1. A pushing component for pushing the tray 54 loaded with glutinous rice balls forward for packaging is provided on the right side of the mounting frame 1, and a sorting component for adjusting the glutinous rice balls that are not aligned with the grooves in the tray 54 is provided on the mounting frame 1.

[0038] When using the device, the first electric push rod 4 extends and drives the first baffle 41 to slide to the left. After the first baffle 41 slides to the left and opens, the glutinous rice balls in the placement frame 3 will enter each compartment of the fixed frame 51 one by one along the unloading channel. When each compartment of the fixed frame 51 is filled with three glutinous rice balls, the glutinous rice balls on the top can no longer enter, and the first electric push rod 4 shortens and drives the first baffle 41 to slide to the right. The first baffle 41 has to block the glutinous rice balls behind in the placement frame 3 to the right. When the first conveying group 2 drives the tray 54 to move to the right to the bottom of the fixed frame 51, the second electric push rod 531 extends and drives the contact frame 532 to move downward. The contact frame 532 moves downward to squeeze the cam 533, and then drives the hinged frame 53 to rotate downward and open. The torsion spring 530 is deformed. After the hinged frame 53 rotates downward and opens, the eighteen glutinous rice balls in the fixed frame 51 fall out through the unloading port and fall into the tray 54. After the glutinous rice balls fall, the second electric push rod 531 shortens and drives the contact frame 532 to move downward. The contact frame 532 moves downward to squeeze the cam 533, and then drives the hinged frame 53 to rotate downward and open. The torsion spring 530 is deformed. After the hinged frame 53 rotates downward and opens, the eighteen glutinous rice balls in the fixed frame 51 fall out through the unloading port and fall into the tray 54. After the glutinous rice balls fall, the second electric push rod 531 shortens and drives the first baffle 41 to slide to the right. The contact frame 532 is driven to move upward and reset. At this time, under the action of the torsion spring 530 resetting, the hinge frame 53 is closed upward, and the eighteen dumplings falling into the tray 54 just correspond to the eighteen placement grooves, avoiding the situation where there are too many or too few dumplings. After the tray 54 is loaded with dumplings, it continues to be transported to the right. When the tray 54 moves under the pushing plate 52, the pushing plate 52 can push the accumulated dumplings flat, which helps the dumplings to enter each placement groove. After the tray 54 loaded with dumplings is transported to the right, the next empty tray 54 moves to the bottom of the fixed frame 51, and the above action is repeated to load the next tray 54. The tray 54 loaded with dumplings continues to move to the right and will be sorted by the sorting component, and then the dumplings that have not entered the placement grooves will be pushed into the placement grooves to ensure the placement position of each dumpling. Then the tray 54 is pushed forward to the second conveying member 55 by the pushing component, and is bagged and packaged by the packaging structure 551.

[0039] like Figure 2 , Figure 6 and Figure 7 As shown, the push-out assembly includes an electric slide rail 56 and a push rack 561 . The electric slide rail 56 is fixedly connected to the upper right portion of the mounting frame 1 , and the push rack 561 is slidably connected inside the electric slide rail 56 .

[0040] When using this device, after the tray 54 loaded with glutinous rice balls moves to the right to under the electric slide rail 56, the electric slide rail 56 controls the pushing frame 561 to slide forward, so that the tray 54 on the first conveying group 2 can be pushed forward to the second conveying member 55, and the tray 54 is conveyed forward by the second conveying member 55, and then bagged and packaged by the packaging structure 551. After the tray 54 is pushed forward, the electric slide rail 56 drives the pushing frame 561 to slide backward and reset.

[0041] like Figure 2 , Figure 8 , Fig. 9and Fig.10 As shown, the finishing assembly includes a fixed plate 61, a connecting plate 62, a first spring 621, a guide rail 622, a contact plate 63, a guide plate 64, a connecting frame 65, a contact rod 66 and a second spring 661. A front-to-rear symmetrical fixed plate 61 is fixedly connected to the right upper side of the mounting frame 1. A connecting plate 62 is slidably connected inside the fixed plate 61. Two first springs 621 are connected between the connecting plate 62 and the adjacent fixed plate 61. A guide rail 622 is slidably connected to the connecting plate 62. A contact plate 63 is fixedly connected between the front and rear guide rails 622. The lower side of the contact plate 63 is provided with a left-right symmetrical arc-shaped protrusion, which is used to align with the gap between the grooves of the tray 54 and push the offset glutinous rice balls into the grooves. The upper side of the contact plate 63 is fixedly connected to a guide plate 64, and the upper side of the pushing frame 561 is fixedly connected to a connecting frame 65. The left part of the connecting frame 65 is slidably connected to a contact rod 66. The rear end of the guide plate 64 is wedge-shaped, and a guide groove is opened on the upper side of the guide plate 64. The rear part of the guide groove is straight and the front part is serrated. The contact rod 66 is inserted into the guide groove, and a second spring 661 is connected between the contact rod 66 and the connecting frame 65.

[0042] When using the device, the push frame 561 slides forward and drives the connecting frame 65 to move forward. The connecting frame 65 moves forward and drives the contact rod 66 to move forward. The contact rod 66 moves forward to squeeze the guide plate 64 to move downward. The guide plate 64 moves downward and drives the contact plate 63, the guide rail 622 and the connecting plate 62 to move downward. The first spring 621 is deformed, and the contact plate 63 moves downward and covers the tray 54 below. At this time, the arc-shaped protrusion below the contact plate 63 is aligned with the gap between the grooves of the tray 54. When the contact rod 66 moves forward to the serrated part of the guide groove, the contact rod 66 continues to move forward and squeezes the guide plate 64 to move left and right. The guide plate 64 The left and right movement drives the contact plate 63 to move left and right. When the contact plate 63 moves left and right, the offset glutinous rice balls can be pushed into the groove to ensure the placement of each glutinous rice ball. Under the action of the expansion and contraction of the second spring 661, the connecting frame 65 can slide on the contact rod 66 to adapt to the continued forward travel of the pushing frame 561 to avoid being stuck by the contact rod 66. When the pushing frame 561 moves backward and resets, the connecting frame 65 will also drive the contact rod 66 to move backward. When the contact rod 66 moves backward and no longer squeezes the guide plate 64, under the action of the first spring 621 resetting, the connecting plate 62 drives the guide rail 622, the contact plate 63 and the guide plate 64 to move upward and reset.

[0043] Embodiment 2: Based on embodiment 1, Figure 1 , Figure 2 , Fig.11 and Fig.12As shown, it also includes an insulation component for preventing the glutinous rice balls from softening. The insulation component includes a shell 71, a first temperature control plate 72, a second temperature control plate 721 and a fan 73. The shell 71 is fixedly connected to the upper side of the mounting frame 1, the first temperature control plate 72 is fixedly connected to the upper part of the placement frame 3, the second temperature control plate 721 is fixedly connected to the middle part of the shell 71, and the fan 73 is fixedly connected to the left part of the shell 71.

[0044] When the device is used, the shell 71 covers the entire first conveying group 2 to keep warm and delay the softening of the glutinous rice balls, while the first temperature control plate 72 and the second temperature control plate 721 can directly perform cooling to ensure that the interior of the shell 71 remains low in temperature to prevent the glutinous rice balls from softening. The fan 73 can blow cold air to the right to ensure that the glutinous rice balls will not soften when being conveyed to the right.

[0046] When the device is used, the tray 54 is stacked in the material frame 81 and blocked by the second baffle 82. When the convex strip on the first conveying group 2 moves to the right, it squeezes the rubber rod 83 to move to the right. The rubber rod 83 moves to the right and drives the second baffle 82 to slide to the right. The first elastic rope 821 is deformed. When the second baffle 82 slides to the right, it drives the third baffle 85 to move to the right through the telescopic frame 86. After the third baffle 85 moves to the right, it is inserted into the material frame 81, and then blocks the top of the bottom tray 54. The second elastic rope 84 and the telescopic frame 86 can also adapt to the extra travel of the second baffle 82 to the right. When the second baffle 82 slides to the right and completely disengages from the tray 54, the bottom tray 54 is 4 falls on the first conveying group 2. When the second baffle 82 slides to the right for a limit distance, the convex strip on the first conveying group 2 continues to move to the right and squeezes the rubber rod 83 to deform and then detach. At this time, under the action of the first elastic rope 821 being restored, the second baffle 82 slides to the left and restores accordingly. The second baffle 82 slides to the left and drives the third baffle 85 to slide to the left and restore through the telescopic frame 86. At this time, the rear tray 54 falls downward on the second baffle 82. When the next convex strip moves to the right and contacts the rubber rod 83, the above actions are repeated to place the trays 54 in the material frame 81 one by one on the first conveying group 2, so that the trays 54 containing the glutinous rice balls can be transported to the right for packaging.
