Description

Technical Field

[0001] This utility model relates to the field of zongzi leaf packaging technology, and in particular to a zongzi leaf packaging device. Background Technology

[0002] A bamboo leaf packing machine is a specialized piece of equipment used to compress and pack bamboo leaves for making zongzi (sticky rice dumplings). It effectively reduces the volume of the leaves, facilitating transportation and storage. It is primarily suitable for bamboo leaf growers, buyers, and zongzi processing companies. Its core function is to compress loose bamboo leaves into neat bundles using mechanical pressure, improving logistics efficiency and reducing storage and transportation costs.

[0003] A zongzi leaf packing machine disclosed in Chinese Patent Publication No. CN221874577U, is equipped with a fixed rod, side plate, cylinder, and pressure plate. Workers place zongzi leaves inside the packing main frame, and then the output end of the cylinder moves downwards, causing the pressure plate to press down inside the packing main frame, thus compressing the zongzi leaves tightly. This facilitates packing a large quantity of zongzi leaves. However, according to related technologies and existing technologies, after compressing and packing the zongzi leaves, the packed leaves need to be removed from the placement space, which is located below the pressure plate. This restricts the removal of the leaves, making it inconvenient and posing certain safety hazards. Furthermore, because the zongzi leaves are compressed during packing, they expand slightly to both sides, pressing against the side walls. This increases friction when removing the leaves, making them difficult to remove and also causing wear and tear on the sides of the leaves. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art, solve the problems mentioned in the background art, and provide a zongzi leaf packaging device.

[0005] The purpose of this utility model is achieved through the following technical solution: a zongzi leaf packaging device, including a base plate, a lifting frame fixedly provided on the outer side of the base plate, a pressing component for compressing zongzi leaves installed on the top of the lifting frame, a supporting component for sliding zongzi leaves out of the bottom of the lifting frame located below the pressing component on the base plate, a limiting component for pushing the limiting component outward on both sides of the supporting component near the lifting frame, an expansion component for pushing the limiting component outward on the bottom of the supporting component, a trigger rack fixedly provided on the base plate for cooperating with the expansion component, a gate installed on the side of the lifting frame near the trigger rack, and a back plate fixedly provided on the side of the lifting frame away from the gate.

[0006] Preferably, the support assembly includes a support plate located at the bottom of the lifting frame, two horizontal mounting plates are fixedly provided at the bottom of the support plate, and two vertical sliding strips are fixedly provided at the bottom of the two mounting plates, and the mounting plates are slidably connected to the base plate through the sliding strips.

[0007] Preferably, the limiting component includes a side plate that fits against the side of the lifting frame, and two limiting strips are fixedly provided at the bottom of the side plate. The side plate is slidably connected to the mounting plate through the limiting strips.

[0008] Preferably, the expansion assembly includes a gear rotatably mounted at the center of the bottom of the support plate. Push rods are provided on both sides of the gear, and teeth are provided at the positions corresponding to the gear on both push rods. The teeth mesh with the upper half of the gear, and the ends of the two push rods away from the gear are fixedly connected to the two side plates respectively.

[0009] Preferably, the pressing assembly includes a hydraulic cylinder fixed to the top of the lifting frame, the output end of the hydraulic cylinder passing downward through the lifting frame and fixedly mounted with a pressure plate, and multiple sliding rods fixedly provided on the top of the pressure plate, the sliding rods being slidably connected to the lifting frame.

[0010] Preferably, a handle is fixedly provided on the side of the support plate near the gate.

[0013] Beneficial effects:

[0014] This bamboo leaf packaging device, by incorporating a support component, a limiting component, and an outward expansion component, features a pullable support plate. After packaging, the support plate, along with the bamboo leaves, is moved out from under the pressure plate, preventing operators from working near the pressure plate, reducing safety hazards, and making it easier to remove the bamboo leaves.

[0027] Additional aspects and advantages of this invention will be further set forth in the description which follows in conjunction with the accompanying drawings, in part of which will be obvious from the description or may be learned by practice of the invention.

[0028] like Figures 1 to 9 As shown, a zongzi leaf packaging device includes a base plate 1, a lifting frame 2 fixedly mounted on the outer side of the base plate 1, a pressing component 3 for compressing zongzi leaves mounted on the top of the lifting frame 2, a supporting component 4 for sliding zongzi leaves out of the bottom of the lifting frame 2 located below the pressing component 3 on the base plate 1, and a limiting component 5 for pushing the limiting components 5 outwardly on both sides of the supporting component 4 near the lifting frame 2, and an expanding component 6 for pushing the limiting components 5 outwardly on the bottom of the supporting component 4, a trigger rack 7 for cooperating with the expanding component 6 fixed on the base plate 1, a gate 11 mounted on the side of the lifting frame 2 near the trigger rack 7, and a back plate 12 fixedly mounted on the side of the lifting frame 2 away from the gate 11; the gate 11, the back plate 12, and the limiting components 6 are all connected to the lifting frame 2. Component 5 encloses and forms a space for placing zongzi leaves. During operation, the zongzi leaves are first layered and placed into the space under the support of the supporting component 4. Then, the lifting frame 2 supports the pressing component 3 to compress and pack the zongzi leaves. After packing, the pressure plate 32 is reset. At this time, the gate 11 is opened, and the supporting component 4 is pulled out to the outside of the pressing component 3, which facilitates the removal of zongzi leaves and reduces safety hazards. In addition, during the process of pulling out the supporting component 4, the rack 7 and the outward expansion component 6 are triggered to move away from the zongzi leaves simultaneously, releasing the compression state on the zongzi leaves, reducing the resistance to the removal of zongzi leaves, and making it easier to remove zongzi leaves. At the same time, the zongzi leaves do not rub against the limiting component 5 when they are removed, avoiding wear and tear on the zongzi leaves and improving product quality.

[0029] like Figure 1 As shown, the pressing component 3 includes a hydraulic cylinder 31 fixed to the top of the lifting frame 2. The output end of the hydraulic cylinder 31 passes through the lifting frame 2 and is fixedly installed with a pressure plate 32. Multiple sliding rods 33 are fixedly provided on the top of the pressure plate 32. The sliding rods 33 are slidably connected to the lifting frame 2. The lifting frame 2 supports the hydraulic cylinder 31 to drive the pressure plate 32 to move downward under the guidance of the sliding rods 33, so as to compress and pack the zongzi leaves.

[0030] like Figure 1 , Figure 2 and Figure 7As shown, the supporting component 4 includes a supporting plate 41 located at the bottom of the lifting frame 2. Two horizontal mounting plates 42 are fixedly provided at the bottom of the supporting plate 41, and two vertical sliding strips 43 are fixedly provided at the bottom of the two mounting plates 42. The mounting plates 42 are slidably connected to the base plate 1 through the sliding strips 43. A handle 10 is fixedly provided on the side of the supporting plate 41 near the gate 11. When the gate 11 is opened, the supporting plate 41 is pulled by the handle 10, and the supporting plate 41 is pulled out as a whole under the sliding support of the sliding strips 43 at the bottom of the mounting plate 42, which facilitates the removal of the bamboo leaves and reduces safety hazards.

[0031] like Figure 4 and Figure 8 As shown, the limiting component 5 includes a side plate 51 that fits against the side of the lifting frame 2. Two limiting strips 52 are fixedly provided at the bottom of the side plate 51. The limiting strips 52 are T-shaped. The mounting plate 42 and the corresponding positions of the limiting strips 52 are provided with limiting grooves 8 for the limiting strips 52 to slide. The side plate 51 is slidably connected to the mounting plate 42 through the limiting strips 52. Under the constraint of the limiting strips 52, the side plate 51 expands outward along the limiting grooves 8, away from the zongzi leaves, relieves the squeezing state of the zongzi leaves, reduces the resistance to removing the zongzi leaves, and facilitates the removal of the zongzi leaves. At the same time, the zongzi leaves do not rub against the side plate 51 when they are removed, avoiding wear and tear on the zongzi leaves and improving product quality.

[0032] like Figures 2 to 9 As shown, the expansion assembly 6 includes a gear 61 rotatably mounted at the center of the bottom of the support plate 41. Push rods 62 are provided on both sides of the gear 61, and teeth 63 are provided at positions corresponding to the gear 61 on both push rods 62. The teeth 63 mesh with the upper half of the gear 61. The ends of the two push rods 62 away from the gear 61 are fixedly connected to two side plates 51 respectively. A clearance groove 9 is provided on the bottom plate 1 for the gear 61 to pass through. The lower half of the gear 61 extends into the clearance groove 9. The trigger rack 7 is fixed inside the clearance groove 9 and meshes with the gear 61 when the support plate 41 is moved out. During the process of pulling out the support plate 41, the gear 61 at the bottom of the support plate 41 moves within the clearance groove 9. When the support plate 41 moves out of the pressure plate 32, the rack 7 and gear 61 are engaged, forcing gear 61 to rotate and engage with the teeth 63 on push rod 62. This causes push rod 62 to push side plate 51 outward along limit groove 8 under the constraint of limit strip 52, so that the two side plates 51 automatically move away from the zongzi leaves, releasing the squeezing state of the zongzi leaves, reducing the resistance to removing the zongzi leaves, and facilitating the removal of the zongzi leaves. After the zongzi leaves are removed, push the support plate 41 to reset, triggering rack 7 to engage gear 61 again to reverse, and push rod 62 to pull side plate 51 to automatically retract, so that support plate 41 and side plate 51 are smoothly returned to the bottom of lifting frame 2, completing one packing cycle and preparing for the next operation.

[0033] The work process is as follows:

[0034] S1: As Figure 1As shown, the gate 11, back panel 12 and two side panels 51 enclose a space for placing zongzi leaves. When in use, the zongzi leaves are first laid in layers in the space under the support of the support plate 41. Then, the lifting frame 2 supports the hydraulic cylinder 31 to drive the pressure plate 32 down to compress and pack the zongzi leaves.

[0035] S2: As Figure 1 and Figure 7 As shown, after the packaging is completed, the pressure plate 32 is reset. At this time, the gate 11 is opened, and the support plate 41 is pulled by the handle 10. Under the sliding support of the bottom slide bar 43 of the mounting plate 42, the support plate 41 is pulled out to the outside of the pressure plate 32, which makes it easier to take out the bamboo leaves and reduces safety hazards.

[0036] S3: As Figure 3 and Figure 8 As shown, during the process of pulling out the support plate 41, the bottom gear 61 of the support plate 41 moves in the relief groove 9. When the support plate 41 just moves out of the range of the pressure plate 32, the trigger rack 7 starts to mesh with the gear 61, forcing the gear 61 to rotate and mesh with the teeth 63 on the push rod 62, so that the push rod 62 pushes the side plate 51 to expand outward along the limit groove 8 under the constraint of the limit strip 52.

[0037] S4: As Figure 7 As shown, when the two side plates 51 move away from the bamboo leaves simultaneously, they will release the pressure on the bamboo leaves, reduce the resistance to removing the bamboo leaves, and make it easier to remove the bamboo leaves. At the same time, the bamboo leaves will not rub against the side plates 51 when they are removed, thus avoiding wear and tear on the bamboo leaves and improving product quality.

[0038] S5: As Figures 1 to 3 As shown, after the bamboo leaves are removed, the support plate 41 is pushed to reset, triggering the rack 7 to re-engage the gear 61 and reverse. The push rod 62 pulls the side plate 51 to automatically retract, so that the support plate 41 and the side plate 51 are smoothly returned to the bottom of the lifting frame 2, completing one packing cycle and preparing for the next operation.

[0039] The hydraulic cylinder 31 in this application is a well-known technology in this field, therefore its specific structure and working principle are not described in detail.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
