Technical Field

[0001] The invention belongs to the technical field of packaging machines, in particular to an automatic packaging machine for prepared dishes. Background Art

[0002] Pre-prepared dishes are made from one or more edible agricultural products and their products as raw materials, and are made through industrial pre-processing such as mixing, pickling, tumbling, kneading, molding, frying, deep-frying, baking, boiling, steaming, etc., and then aseptically packaged in packaging boxes. At present, when packaging pre-prepared soup dishes, glass jars are usually used to store them. When packaging them, a label with the product name and the ratio of raw materials is directly sealed on the outside of the glass. When eating, the pre-packaged dishes only need to be heated or cooked before they can be eaten.

[0003] A patent application with publication number CN117485675A discloses an injection mold. The patent sets a guide component, a conveyor belt, etc. When starting to work, the pre-prepared food packaging box is placed on the conveyor belt. At this time, the packaging box will first pass through the guide plate. When the crooked packaging box hits the guide plate, it will be guided by the guide plate. At the same time, the roller on the guide plate will prevent the packaging box from getting stuck, and help the guide plate to guide the crooked packaging box to a vertical state for continued transmission, so as to facilitate the subsequent box packing of the pre-prepared food. Then, by setting a packaging component, etc., when the clamping component adjusts the packaging box loaded with the pre-prepared food to a horizontal vertical state and clamps it, the cylinder is started to push the fixed plate downward, so that the bellows is stretched, and the packaging box cover that is sucked by the air pump, the bellows, and the conduit is finally attached to the opening of the packaging box loaded with the pre-prepared food by the suction cup, and the packaging work can be completed. By straightening the packaging box in advance, the packaging efficiency is effectively improved, the work intensity is reduced, and the production efficiency of the pre-prepared food is greatly improved.

[0004] The above-mentioned prior art still has some problems in actual use. Before the packaged boxes storing the pre-prepared soup dishes are transported and packaged, it is inconvenient to limit the packaged boxes to ensure the stability of the packaged boxes during transportation.

Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1-7 , the present invention provides a technical solution:

[0034] A pre-prepared food automatic packaging machine comprises a mounting seat 1, a limiting groove 2 is provided in the middle of the upper end surface of the mounting seat 1, a conveyor belt 3 is arranged in the inner cavity of the limiting groove 2, and the conveyor belt 3 is used to transport the pre-prepared food packaging box 4, a plurality of L-shaped mounting frames 5 are symmetrically fixedly connected to the upper end surface of the mounting seat 1, and a limiting baffle 6 is fixedly connected between the plurality of L-shaped mounting frames 5, a winding column 15 is rotatably connected to one side of the upper end surface of the mounting seat 1, a packaging auxiliary roller 19 is rotatably connected to the upper end surface of the mounting seat 1, and the packaging auxiliary roller 19 is made of non-slip rubber material and is used to drive the pre-prepared food packaging box 4 to rotate to realize packaging and packaging, and a material discharge component 14 is rotatably connected to one side of the upper end surface of the mounting seat 1;

[0035] The discharge assembly 14 includes a rotating column 141 rotatably connected to one side of the upper end surface of the mounting base 1. A through slot 142 is provided inside the rotating column 141. A clamping plate 148 is slidably connected to the inner cavity of the through slot 142. The outside of the rotating column 141 is used to install the packaging label 13.

[0036] Specifically, in the prior art, before the packaged boxes storing pre-prepared dishes are transported and packaged, it is inconvenient to limit the position of the packaged boxes to ensure the stability of the packaged boxes during transportation. If the packaged boxes fall over, the operator needs to stop the packaging machine for adjustment, resulting in low packaging efficiency of the packaged boxes storing pre-prepared dishes.

[0037] When the pre-prepared food packaging box 4 is packaged, the present invention uses the conveyor belt 3 to drive the pre-prepared food packaging box 4 to be transported, and the pre-prepared food packaging box 4 is moved between the limit baffles 6, so that the limit baffles 6 can be used to limit the pre-prepared food packaging box 4, so as to ensure the stability of the pre-prepared food packaging box 4 during the transportation process, and at the same time, the winding column 15 is used to wind and pull the packaging label belt, so that the packaging label belt drives the packaging label 13 to rotate, and then the packaging label 13 drives the rotating column 141 to rotate, so that the packaging label 13 discharges the packaging label belt, and then when the pre-prepared food packaging box 4 moves to the packaging auxiliary roller 19, the pre-prepared food packaging box 4 is adhered to the packaging label on the packaging label belt, and at the same time, the pre-prepared food packaging box 4 is pushed to be tightly attached to the packaging auxiliary roller 19. The packaging auxiliary roller 19 is made of non-slip rubber material, so that the packaging auxiliary roller 19 can drive the pre-prepared food packaging box 4 to rotate clockwise, and then the packaging auxiliary roller 19 is used to drive the pre-prepared food packaging box 4 to rotate, so that the packaging label stuck to the outside of the pre-prepared food packaging box 4 is smoothed, so that the packaging label is completely adhered to the outside of the pre-prepared food packaging box 4, and then the pre-prepared food packaging box 4 is adhered and packaged, thereby solving the problem that the existing automatic packaging machine for pre-prepared food is inconvenient to limit the packaging box before conveying and packaging the packaging box storing the pre-prepared food, so as to ensure the stability of the packaging box during transportation. If the packaging box falls over, the operator needs to stop the packaging machine for adjustment, resulting in low packaging efficiency of the packaging box storing the pre-prepared food.

A driving motor is arranged inside the lower end of the mounting seat 1, and the output shaft end of the driving motor is fixedly connected to the winding column 15.

[0039] Specifically, when arranging the packaging label tape, the packaging label tape is limited by using a plurality of limit posts 16 to ensure the tension of the packaging label tape when it is discharged, and then the winding post 15 is driven to rotate by a driving motor, and the winding post 15 drives the waste packaging label tape to be wound up. During the winding up of the waste packaging label tape, the limiting post 16 is used to limit the packaging label tape carrying the packaging label, thereby improving the stability of the winding and discharge of the packaging label tape and ensuring the packaging efficiency of the packaging box.

[0040] like Figure 1 , Figure 2 and Figure 3As shown, the inner cavity of the through slot 142 is rotatably connected to a bidirectional threaded rod 143, and one end of the bidirectional threaded rod 143 passes through the rotating column 141 and is fixedly connected to a knob 144, the outer surface of the bidirectional threaded rod 143 is threadedly connected to two sliders 145, and the two sliders 145 are rotatably connected to a push rod 146 on the outside, one end of the push rod 146 is rotatably connected to a support block 147, and one end of the support block 147 is fixedly connected to a splint 148.

[0041] Specifically, when packaging the packaging box 4 storing pre-prepared dishes, the packaging label 13 is placed on the outside of the rotating column 141, and the knob 144 is twisted to rotate the bidirectional threaded rod 143, and the bidirectional threaded rod 143 is threaded to drive the two sliders 145 to move away from each other, so that the two sliders 145 drive the push rod 146 to move synchronously. During the movement of the push rod 146, the support block 147 is pushed to move, and the support block 147 pushes the splint 148 to slide out of the inner cavity of the through groove 142, and then the splint 148 is expanded to squeeze and fix the packaging label 13, thereby facilitating the installation and replacement of the packaging label 13 and improving the efficiency of packaging and packing the pre-prepared dishes.

[0042] like Figure 1 to Figure 2 As shown, a triangular label removal block 17 is fixedly connected to the upper end surface of the mounting seat 1, and the triangular label removal block 17 is set in an acute triangle shape for guiding the conveyance of the packaging label belt so that the packaging label can be removed from the packaging label belt.

[0043] Specifically, during the rotation of the winding column 15, the packaging label tape waste is driven to be wound up by the winding column 15, and during the process of the winding column 15 winding up the packaging label tape waste, the packaging label tape with the packaging label will be pulled to move, and the packaging label tape with the packaging label will be attached to the triangular label withdrawal block 17, and the triangular label withdrawal block 17 is set in the shape of an acute triangle, so that when the packaging label tape with the packaging label moves through the acute triangle of the triangular label withdrawal block 17, the packaging label can be separated from the packaging label tape, and then the packaging label is convenient for sticking to the packaging box conveyed by the conveyor belt 3, and the packaging box is packaged and packed at the same time.

[0044] like Figure 1 and Figure 7 As shown, a fixing sleeve 31 is fixedly connected to the outside of the winding column 15 , a tension spring 32 is fixedly connected to the bottom of the inner cavity of the fixing sleeve 31 , and one end of the tension spring 32 is fixedly connected to a T-shaped slider 33 , and one end of the T-shaped slider 33 is fixedly connected to a clamping rod 34 .

[0045] Specifically, when the waste packaging label tape is rolled up, the waste packaging label tape is placed outside the winding column 15, and then the tension spring 32 is used to pull the T-shaped slider 33 to move close to the winding column 15, and the T-shaped slider 33 drives the clamping rod 34 to clamp the waste packaging label tape, so that the waste packaging label tape fits the surface of the winding column 15, thereby facilitating the winding column 15 to clamp and fix the waste packaging label tape, so that the winding column 15 can drive the waste packaging label tape to be rolled up during the rotation process, thereby ensuring the discharge of the packaging label tape with the packaging label.

[0046] Embodiment 2: Figures 1 to 7 As shown in Comparative Example 1, another embodiment of the present invention is:

[0047] like Figure 1 , Figure 4 and Figure 6 As shown, a transmission roller 35 is rotatably connected to the inner cavity of the conveyor belt 3 , one end of the transmission roller 35 is fixedly connected to a transmission bevel gear 36 , the transmission bevel gear 36 is meshingly connected to a driven bevel gear 37 , and the driven bevel gear 37 is fixedly connected to the packaging auxiliary roller 19 .

[0048] Specifically, when the pre-prepared food packaging box 4 is moved by the conveyor belt 3, the conveyor belt 3 drives the transmission roller 35 to rotate, and the transmission roller 35 drives the transmission bevel gear 36 to rotate, and at the same time, the transmission bevel gear 36 engages the driven bevel gear 37 to rotate, and then the driven bevel gear 37 drives the packaging auxiliary roller 19 to rotate, and then the packaging auxiliary roller 19 is used to drive the pre-prepared food packaging box 4 to rotate, and then the pre-prepared food packaging box 4 is packaged and packaged.

[0049] like Figure 1 , Figure 4 and Figure 6 As shown, a fixing plate 7 is fixedly connected to one side of the upper end surface of the mounting seat 1, and a groove 8 is opened on the upper end surface of the fixing plate 7. A screw rod 9 is rotatably connected to the inner cavity of the groove 8, and a T-shaped fixing rod 10 is threadedly connected to the outer surface of the screw rod 9. One end of the screw rod 9 is fixedly connected to the transmission roller 35.

[0050] like Figure 1 , Figure 4 and Figure 6 As shown, a U-shaped push frame 21 is fixedly connected to one end of the T-shaped fixed rod 10, a receiving groove 25 is opened inside one end of the U-shaped push frame 21, a spring 26 is fixedly connected to the bottom of the inner cavity of the receiving groove 25, a T-shaped slide bar 27 is fixedly connected to one end of the spring 26, and an auxiliary roller 20 is rotatably connected inside the T-shaped slide bar 27.

[0051] like Figure 1 , Figure 4 and Figure 6As shown, an L-shaped fixing frame 11 is fixedly connected to one side of the T-shaped fixing rod 10, a push plate 12 is fixedly connected to one end of the L-shaped fixing frame 11, and one end surface of the push plate 12 is fixedly connected to fixing blocks 23 at four corners, pulleys 22 are rotatably connected between the fixing blocks 23, and the pulleys 22 are externally connected to the belts 24 for transmission.

[0052] Specifically, when the conveyor belt 3 drives the transmission roller 35 to rotate, the transmission roller 35 drives the screw rod 9 to rotate, and the screw rod 9 threadably drives the T-shaped fixing rod 10 to move in the inner cavity of the groove 8, and at the same time, the T-shaped fixing rod 10 pushes the U-shaped pushing frame 21 to move close to the packaging auxiliary roller 19, and in the process of the U-shaped pushing frame 21 approaching the packaging auxiliary roller 19, the spring 26 in the inner cavity of the storage groove 25 will bounce up the T-shaped sliding bar 27, and the T-shaped sliding bar 27 drives the auxiliary roller 20 to move close to the packaging auxiliary roller 19, and then the auxiliary roller 20 squeezes and pushes the pre-prepared food packaging box 4 between the packaging auxiliary rollers 19, and then the pre-prepared food packaging box 4 is fitted with the packaging auxiliary rollers 19, and at the same time, the packaging auxiliary rollers 19 are used to drive the pre-prepared food packaging box 4 to rotate, so that the packaging auxiliary rollers 19 cooperate with the auxiliary rollers 20 to roll the packaging label on the outside of the pre-prepared food packaging box 4, so that the packaging label seals and packs the pre-prepared food packaging box 4, and at the T-shaped fixing rod 10 When the fixed rod 10 pushes the U-shaped pushing frame 21 to move close to the packaging auxiliary roller 19, the T-shaped fixed rod 10 will drive the L-shaped fixed frame 11 to move synchronously, and at the same time drive the pushing plate 12 to move, and then use the pushing plate 12 to drive the fixing block 23 to move, and make the fixing block 23 drive the pulley 22 to move synchronously, so that the pulley 22 drives the belt 24 to fit with the pre-prepared food packaging box 4, and then use the pulley 22 to cooperate with the belt 24 to squeeze the pre-prepared food packaging box 4 to prevent the pre-prepared food packaging box 4 from contacting the pre-prepared food packaging box 4 being packaged and packaged, affecting the packaging and packaging of the pre-prepared food packaging box 4, thereby solving the problem that when the existing automatic packaging machine for pre-prepared food is transporting and packaging the packaging box storing pre-prepared food, it is inconvenient to control the entry of the pre-prepared food packaging box to be packaged, resulting in a large number of pre-prepared food packaging boxes to be packaged being accumulated at the packaging and packaging mechanism, making it difficult to remove the packaging label from the packaging label belt of the packaging box, affecting the packaging and packaging of the packaging box.

[0053] like Figure 1 and Figure 5 As shown, the upper end of the limit baffle 6 is located on one side of the packaging auxiliary roller 19 and is fixedly connected to a fixed column 28. The fixed column 28 is rotatably connected to the rotating cylinder 18 outside. A torsion spring 29 is fixedly connected to the upper end of the fixed column 28, and one end of the torsion spring 29 is fixedly connected to the inner wall of the rotating cylinder 18. A plurality of baffle rods 30 are evenly fixedly connected to the outside of the rotating cylinder 18.

[0054] Specifically, after the pre-prepared food packaging box 4 is packaged and packaged, the pre-prepared food packaging box to be packaged is transported in through the conveyor belt and squeezes the packaged pre-prepared food packaging box 4, so that the packaged pre-prepared food packaging box 4 pushes the blocking rod 30 to move, and the blocking rod 30 drives the rotating cylinder 18 to rotate, and the rotating cylinder 18 will drive the torsion spring 29 to twist during the rotation process, so that the packaged pre-prepared food packaging box 4 is discharged and collected, and after the packaged pre-prepared food packaging box 4 moves past the blocking rod 30, the rotating cylinder 18 is twisted to reset by the torsion spring 29, and the rotating cylinder 18 drives the blocking rod 30 to reset, thereby blocking and limiting the pre-prepared food packaging box to be packaged entering the packaging mechanism again, thereby solving the problem that when the existing automatic packaging machine for pre-prepared food is discharging the packaged pre-prepared food packaging box, because the conveyor belt is always in a rotating running state, when the auxiliary roller does not squeeze the packaging box, the packaging box is suddenly affected by the conveying of the conveyor belt, and there will be shaking, tilting and getting stuck on the conveyor belt, which affects the discharge and collection of the packaging box in the later stage.

[0055] According to the working principle, when the pre-prepared food packaging box 4 is packaged, the conveyor belt 3 is used to drive the pre-prepared food packaging box 4 to be transported, and the pre-prepared food packaging box 4 is moved between the limit baffles 6, so that the limit baffles 6 can be used to limit the pre-prepared food packaging box 4 to ensure the stability of the pre-prepared food packaging box 4 during transportation. At the same time, the winding column 15 is used to wind and pull the packaging label belt, so that the packaging label belt drives the packaging label 13 to rotate, and then the packaging label 13 drives the rotating column 141 to rotate, so that the packaging label 13 discharges the packaging label belt, and then the pre-prepared food packaging box 4 moves to When the packaging auxiliary roller 19 is at the packaging auxiliary roller 19, the pre-prepared food packaging box 4 is adhered to the packaging label on the packaging label belt, and at the same time, the pre-prepared food packaging box 4 is pushed to fit closely with the packaging auxiliary roller 19. Since the packaging auxiliary roller 19 is made of non-slip rubber material, the packaging auxiliary roller 19 can drive the pre-prepared food packaging box 4 to rotate clockwise. Then, during the process of driving the pre-prepared food packaging box 4 to rotate by the packaging auxiliary roller 19, the packaging label adhered to the outside of the pre-prepared food packaging box 4 is smoothed, so that the packaging label is completely adhered to the outside of the pre-prepared food packaging box 4, thereby realizing the adhesive packaging of the pre-prepared food packaging box 4.

[0056] After the pre-prepared food packaging box 4 is packaged and packed, the pre-prepared food packaging box to be packaged is transported in through the conveyor belt and squeezes the packaged pre-prepared food packaging box 4, so that the packaged pre-prepared food packaging box 4 pushes the blocking rod 30 to move, and the blocking rod 30 drives the rotating cylinder 18 to rotate, and the rotating cylinder 18 drives the torsion spring 29 to twist during the rotation process, so that the packaged pre-prepared food packaging box 4 is discharged and collected, and after the packaged pre-prepared food packaging box 4 moves past the blocking rod 30, the rotating cylinder 18 is twisted to reset by the torsion spring 29, and the rotating cylinder 18 drives the blocking rod 30 to reset, thereby blocking and limiting the pre-prepared food packaging box to be packaged entering the packaging mechanism again.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
