Description

Technical Field

[0001] This utility model relates to the field of fruit and vegetable processing technology, and in particular to a fruit and vegetable bagging and packaging machine. Background Technology

[0002] With the acceleration of agricultural modernization, the packaging process after fruit and vegetable harvesting has gradually become one of the key points for improving production efficiency. Traditional fruit and vegetable packaging mainly relies on manual operation, which suffers from low efficiency, high cost, and easy damage to fruits and vegetables. In recent years, the research and development of automated packaging equipment has gradually gained attention, and some fruit and vegetable packaging equipment has appeared on the market. However, these devices still have considerable room for improvement in terms of applicability, stability, and cost control.

[0003] Currently, the most common fruit and vegetable packaging equipment is the bagging machine, which requires manual assistance to complete the bagging operation. Although this reduces labor intensity, the efficiency improvement is limited. Furthermore, the use of a single heat-sealing method makes it easy for the opening of the produced product to leak, affecting product quality. Utility Model Content

[0004] This utility model proposes a fruit and vegetable bagging packaging machine, which aims to improve the problem that some existing devices are prone to leaks at the opening of the product, affecting product quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A fruit and vegetable bagging and packaging machine includes a packaging machine frame. A feeding mechanism is located on one outer side of the packaging machine frame, and a discharging mechanism is located on the other outer side of the packaging machine frame. A sealing mechanism is installed inside the packaging machine frame. The sealing mechanism includes a side mounting plate b, the outer side of which is fixedly connected to the inside of the packaging machine frame. A top mounting plate b is fixedly connected to the top of the side mounting plate b, and a thermoplastic sealing head is fixedly connected to the bottom of the top mounting plate b. Two protective components are fixedly connected to the inner side of the side mounting plate b. A drive shaft a is rotatably connected inside the protective components. A driving bevel gear is fixedly connected to one side of the drive shaft a. A rotating shaft b is rotatably connected inside the protective components. A driven bevel gear is fixedly connected to the top of the rotating shaft b. The outer sides of the driving bevel gear and the outer sides of the driven bevel gear are meshed with each other. A pressure roller is fixedly connected to the bottom of the driven bevel gear.

[0007] The above solution allows the fruit and vegetable bagging machine to achieve heat sealing through the heat sealing head of the sealing mechanism on the basis of feeding and discharging. At the same time, through the connection and cooperation of various components in the protective assembly, the pressing roller can play a pressing role in the sealing process, thereby effectively improving the quality and efficiency of fruit and vegetable bagging.

[0008] As a further description of the above technical solution:

[0009] The protective assembly includes a fixed base, one outer side of which is fixedly connected to the outside of the side mounting plate b, and a protective housing is fixedly connected to the outer side of the fixed base. The two rotating shafts b are rotatably connected to the inside of the protective housing.

[0010] The above solution securely connects the protective components to the packaging machine frame via a fixed base and protects the rotating shaft b with a protective shell. This not only prevents external debris from interfering with the rotation of the rotating shaft b but also provides a reliable support structure for the rotating shaft b. This ensures that the rotating shaft b rotates stably during the operation of the sealing mechanism and cooperates with components such as the driven bevel gear to achieve the pressing function, effectively improving the durability of the protective components and the reliability of the sealing mechanism.

[0011] As a further description of the above technical solution:

[0012] The bottom of the packaging machine frame is provided with a film packaging conveying mechanism, the bottom of the packaging machine frame and the side of the film packaging conveying mechanism are provided with a driving mechanism, and the inside of the packaging machine frame is provided with a cutting mechanism.

[0013] Through the above solution: the film packaging conveying mechanism set at the bottom of the packaging machine frame can realize the stable conveying of film packaging materials, the drive mechanism on its side can provide power support for film conveying and the operation of the whole machine, and the cutting mechanism inside the frame can accurately cut the film according to packaging needs. The three work together to form a continuous automated process in the film conveying, power supply and cutting links of the packaging machine, which effectively improves the efficiency and accuracy of film handling in the fruit and vegetable bagging process, ensures that packaging materials are conveyed and accurately cut as needed, and thus ensures the stability of the overall operation of the packaging machine and the orderliness of the packaging operation.

[0014] As a further description of the above technical solution:

[0015] The feeding mechanism includes a feeding conveyor belt frame, a baffle-type conveyor belt a is rotatably connected to the inner side of the feeding conveyor belt frame, a drive motor a is fixedly connected to one side of the feeding conveyor belt frame, a plurality of conveyor belt rotating shafts are rotatably connected inside the feeding conveyor belt frame, and two conveyor belt inner support frames are provided inside the feeding conveyor belt frame, with the tops of the two conveyor belt inner support frames contacting the inner wall of the baffle-type conveyor belt a.

[0016] Through the above scheme: the feeding mechanism, through the baffle conveyor belt a rotatably connected to the inner side of the feeding conveyor belt frame, cooperates with the drive motor a on one side and multiple internal conveyor belt rotating shafts. Under the power drive of the drive motor a, the baffle conveyor belt a can be stably operated to transport the fruits and vegetables to be packaged. The two conveyor belts inside the frame that contact the inner wall of the baffle conveyor belt a are supported by the support frame, which can effectively support the conveyor belt and prevent it from deforming or shifting during the transportation process. This ensures the smoothness and continuity of the fruit and vegetable transportation during the feeding process, and ensures that the fruits and vegetables to be packaged can enter the packaging machine accurately and orderly for subsequent processing.

[0017] As a further description of the above technical solution:

[0018] The discharge mechanism includes a baffle-type conveyor belt b, which is installed on the other side of the packaging machine frame. A linkage shaft a is fixedly connected to the bottom of the packaging machine frame, and a transmission belt a is provided between the linkage shaft a and the baffle-type conveyor belt b.

[0019] Through the above solution: the baffle conveyor belt b of the discharge mechanism is installed on the other side of the packaging machine frame to transport the packaged fruits and vegetables. The linkage shaft a at the bottom of the packaging machine frame is connected to the baffle conveyor belt b through the transmission belt a. This structural design can use the linkage shaft a to stably transmit the power of the drive mechanism to the baffle conveyor belt b through the transmission belt a, realizing the linkage between the discharge process and the whole machine power system. This can ensure that the baffle conveyor belt b and the feeding mechanism, sealing mechanism and other components operate in the same rhythm, and can reduce the impact and vibration during the power transmission process through the flexible transmission of the transmission belt a. This ensures that the packaged fruits and vegetables can be output from the packaging machine smoothly and efficiently, avoiding problems such as discharge jamming or unstable conveying caused by poor power connection.

[0020] As a further description of the above technical solution:

[0021] The film packaging conveying mechanism includes a mounting plate a, which is externally and fixedly connected to the inside of the packaging machine frame. An extension frame is fixedly connected to one side of the top of the mounting plate a, and an inlet guide roller is rotatably connected to the inner side of the extension frame. A film roll placement roller is rotatably connected to the inner side of the bottom of the mounting plate a, and a middle connecting guide roller is rotatably connected to the top of the mounting plate a.

[0022] Through the above scheme: the film packaging conveying mechanism is fixed inside the packaging machine frame by the mounting plate a to form a stable support structure. The inner side of the extension frame on the top side is rotatably connected to the feed port guide roller, which can guide the path of the film into the packaging machine. The inner side of the bottom film roll placement roller is used to carry the film roll and enable it to unfold smoothly. The middle connecting guide roller rotatably connected at the top can play a transition support and tension adjustment role during the film conveying process. This multi-component cooperative structural design can ensure that the film is conveyed smoothly and orderly from the placement roll to the feed port, effectively avoiding problems such as film deviation, wrinkles or uneven tension during the conveying process.

[0023] As a further description of the above technical solution:

[0024] The driving mechanism includes a drive motor b, which is externally fixedly connected to the bottom of the packaging machine frame. Two connecting shafts a are rotatably connected to the top inner side of the packaging machine frame. A transmission sprocket a is fixedly connected to the outside of the connecting shaft a. A transmission chain a is externally coupled to the two transmission sprockets a. Multiple connecting gears are provided on the inner wall of the packaging machine frame. The multiple connecting gears are externally coupled to the drive chain a.

[0025] Through the above scheme: the drive mechanism is powered by a drive motor b fixed to the bottom of the packaging machine frame. The two connecting shafts a rotatably connected to the top of the inner side of the frame and the external transmission sprockets a transmit power synchronously through the transmission chain a. Multiple connecting gears set on the inner wall form a linkage structure through the drive chain a. This design can stably and efficiently transmit the power of the drive motor b to each moving part of the packaging machine. By cooperating with the transmission sprocket and chain, and the connecting gears and drive chain, slippage or energy loss during power transmission is reduced, ensuring that the feeding mechanism, discharging mechanism, sealing mechanism and film packaging conveying mechanism and other components operate in a coordinated manner according to the set rhythm.

[0026] As a further description of the above technical solution:

[0027] The cutting mechanism includes a drive shaft a and a drive shaft b. The drive shaft a and the drive shaft b are rotatably connected to the inside of the packaging machine frame. A drive gear a and a driven gear b are fixedly connected to the outside of the drive shaft a and the drive shaft b, respectively. The drive gear a and the driven gear b are meshed with each other. A lower cutter and an upper cutter are fixedly connected to the outside of the drive shaft a and the drive shaft b, respectively.

[0028] Through the above solution: the drive shafts a and b of the cutting mechanism are rotatably connected inside the packaging machine frame. The drive gear a and driven gear b, which are fixed externally, are connected by meshing to achieve stable power transmission, so that the drive shafts a and b can rotate synchronously and in coordination. This drives the lower cutter and upper cutter fixed on the two shafts to form a precise cutting action. This gear transmission structure can ensure that the movement rhythm of the upper and lower cutters is consistent and the force is uniform during the cutting process, effectively avoiding the problem of film cutting deviation or tearing caused by unstable transmission. This achieves precise cutting of film packaging materials, provides packaging materials with uniform size for the subsequent sealing process, and ensures the standardization of fruit and vegetable bagging and the quality of finished products.

[0049] Specifically, the film packaging conveying mechanism 4 at the bottom of the packaging machine frame 1 is fixed inside the frame via mounting plate a401 to form a stable support structure. The feed guide roller 403, rotatably connected to the inner side of the extension frame 402 on the top side, guides the path of the film entering the packaging machine. The film roll placement roller 404, rotatably connected to the inner side of the bottom, carries the film roll and allows it to unfold smoothly. The middle connecting guide roller 405, rotatably connected to the top, plays a transitional support and tension adjustment role during film conveying. The three components work together to ensure that the film is conveyed smoothly and orderly from placement to the feed inlet, avoiding problems such as offset, wrinkles, or uneven tension. The drive mechanism 5 at the bottom of the packaging machine frame 1 and located on the side of the film packaging conveying mechanism 4 is fixed to the bottom of the frame via drive motor b501. The power source is provided by two connecting shafts a502 rotatably connected to the top of the inner side of the frame. The external transmission sprocket a503 transmits power synchronously through the transmission chain a504. Multiple connecting gears set on the inner wall form a linkage structure through the drive chain a505, ​​which stably and efficiently transmits the power of the drive motor b501 to each moving part of the packaging machine, reducing slippage and energy loss in power transmission. This ensures that the film packaging conveying mechanism 4, the feeding mechanism 2, the discharging mechanism 3, the sealing mechanism 6 and other components operate in coordination according to the set rhythm.

[0050] Reference Figure 1 , Figure 3 , Figure 6The packaging machine frame 1 is equipped with a cutting mechanism 7. The cutting mechanism 7 includes a drive shaft a701 and a drive shaft b704. The drive shaft a701 and the drive shaft b704 are rotatably connected to the outside of the packaging machine frame 1. The drive shaft a701 and the drive shaft b704 are respectively fixedly connected to the outside of the drive shaft a702 and the driven gear b705. The drive gear a702 and the driven gear b705 are meshed with each other. The drive shaft a701 and the drive shaft b704 are respectively fixedly connected to the outside of the drive shaft a703 and the upper cutter 706.

[0051] Specifically, in the cutting mechanism 7 inside the packaging machine frame 1, the drive shafts a701 and b704 are rotatably connected inside the frame. The drive gears a702 and b705, which are fixed externally to the two shafts, are meshed to form a stable power transmission structure. This structure can drive the drive shafts a701 and b704 to rotate synchronously and in a coordinated manner, thereby driving the lower cutter 703 and upper cutter 706 fixed on the two shafts to achieve precise cutting. This meshing transmission method composed of the drive gear a702 and the driven gear b705 can ensure that the movement rhythm of the upper and lower cutters 703 and 706 is consistent and the force is uniform during the cutting process. This effectively avoids the problem of film cutting deviation or tearing caused by unstable transmission, thereby achieving precise cutting of film packaging materials. This provides packaging materials with uniform size for the subsequent sealing process, ensuring the standardization of fruit and vegetable bagging and the quality of finished products. At the same time, the high reliability of the gear transmission also provides support for the long-term stable operation of the cutting mechanism 7, ensuring the efficiency and accuracy of the packaging machine in the film processing stage.

[0052] Compared with some existing devices, the packaging machine frame 1 is equipped with a sealing mechanism 6 inside. Rotating pressing rollers 6010 are provided on both sides of the heat-sealing head 603, which can press out a certain shape and make its position more accurate before sealing. After heat sealing, pressing is performed again, making the sealed edge more secure and preventing opening. This reduces the risk of leakage at the opening of products produced by some devices, which affects product quality. The drive mechanism 5 is used for driving, so that the drive motor b501 in the drive mechanism 5 can drive the structure at multiple different positions of the device to rotate through multiple chain structures, thereby enhancing the linkage of the device, making its processing coordination higher, and improving efficiency.

[0053] Working principle: When the packaging machine is working, the fruits and vegetables to be packaged are driven by the drive motor a203 of the feeding mechanism 2 to rotate the baffle conveyor belt a202. With the auxiliary rotation of the conveyor belt rotating shaft 204 and the support of the inner support frame 205 of the conveyor belt, they are conveyed to the inside of the packaging machine frame 1 through the feeding conveyor belt frame 201. At the same time, the film roll placement roller 404 on the inner side of the bottom of the mounting plate a401 in the film packaging conveying mechanism 4 carries the film roll. After the film is unfolded, it is guided in sequence through the top rotating connecting guide roller 405 and the feed port guide roller 403 on the inner side of the extension frame 402, and conveyed towards the cutting mechanism 7. The drive motor b501 of the drive mechanism 5 is fixed to the bottom of the packaging machine frame 1 to provide power. Through the linkage of the transmission sprocket a503 on the inner top rotating connecting shaft a502, the transmission chain a504, and the connecting gear set on the inner wall with the drive chain a505, ​​the power is transmitted to each moving part. The main cutting mechanism 7... Driven shaft a701 and driven shaft b704 rotate synchronously under the meshing transmission of driven gear a702 and driven gear b705, driving the lower cutter 703 and upper cutter 706 fixed on the two shafts to cut the conveyed film to the required size; the cut film wraps the fruits and vegetables and enters the sealing mechanism 6, where the thermoplastic sealing head 603 at the bottom of the top mounting plate b602 heat seals the film, while the active bevel gear on one side of the drive shaft a606 in the inner protective assembly of the side mounting plate b601 heat seals the film. Wheel 607 meshes with the driven bevel gear 609 at the top of the rotating shaft b608, driving the pressing wheel 6010 at the bottom of the driven bevel gear 609 to rotate and press the edges of the film before and after heat sealing; finally, the packaged fruits and vegetables are conveyed by the baffle conveyor belt b301 of the discharge mechanism 3. This conveyor belt is driven by the drive mechanism 5 through the linkage shaft a302 at the bottom of the packaging machine frame 1 and the transmission belt a303 between them, and outputs the finished product from the other side of the packaging machine frame 1.
