Description

Technical Field

[0001] This utility model relates to the technical field of fruit packaging devices, specifically a packaging bag feeding mechanism for a fruit packaging machine. Background Technology

[0002] A fruit packaging machine is a type of mechanical equipment specifically designed for packaging fruit. Its main function is to package the fruit to ensure that it remains fresh and intact during transportation and sales.

[0003] For example, a packaging machine for walnut processing, with publication number CN221017410U, uses a push rod to push the walnuts over a slag-blocking bar, which in turn blocks the smaller, broken fruits and shells, thus separating the broken fruits and shells from the walnuts and improving the quality of the packaged walnuts. Furthermore, by repeatedly lifting the support with a lever, the sorting channel vibrates, causing the broken fruits and shells to slide into the discharge channel and be discharged, preventing the broken fruits and shells from accumulating in the sorting channel.

[0004] However, in the aforementioned prior art, when using sorting components to sort walnuts and feed them into packaging bags, the sorting components cannot classify and group walnuts of different sizes. Directly putting walnuts of different sizes into packaging bags without sorting them will reduce the neatness and aesthetics of the packaging. Utility Model Content

[0005] The purpose of this utility model is to provide a bag feeding mechanism for a fruit packaging machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bag feeding mechanism for a fruit packaging machine, comprising a base frame, a feeding assembly, and a sieving assembly. Both the sieving assembly and the feeding assembly are mounted on the base frame. The feeding assembly includes a brake motor, a feeding frame, a first sieve barrel, a second sieve barrel, and a third sieve barrel. The inner wall of the feeding frame has a first groove, a second groove, and a third groove. The output shaft of the brake motor is fixedly connected to a first shaft. One end of the first sieve barrel is fixedly connected to a second shaft. A driving wheel and a driven wheel are respectively fixedly sleeved on the first and second shafts. The driving wheel and the driven wheel are connected by a first conveyor belt. A third shaft is fixedly connected inside the first sieve barrel. Four... Shafts 1 and 5 are connected. One end of shafts 3 and 4 is fixedly fitted with drive wheels 1 and 2, respectively. Drive wheels 1 and 2 are connected by a conveyor belt 2. One end of shaft 4, away from drive wheel 2, and one end of shaft 5 are fixedly fitted with drive wheels 3 and 4, respectively. Drive wheels 3 and 4 are connected by a conveyor belt 3. The side wall of the feeding frame has discharge holes 1, 2, and 3. Discharge holes 1, 2, and 3 are connected to slots 1, 2, and 3, respectively. A collection frame is placed below the outer side of each discharge hole 1, 2, and 3, and each of the three collection frames contains a packaging bag. After the fruit residue and debris are removed by the screening mechanism, the brake motor can be started to rotate shaft one, which in turn drives shaft two and screen barrel one via conveyor belt one. Then, drive wheels one and two, through conveyor belt two, drive wheels three and four, drive screen barrel two and screen barrel three to rotate respectively. At this time, the fruit passes through the surfaces of screen barrel one, screen barrel two and screen barrel three in sequence within the feeding frame, and falls into the discharge holes one, two and three through their different holes. This completes the feeding process of the fruit in the packaging bags in the three collection frames, making the fruit in the packaging bags the same size, more neat and beautiful.

[0007] Preferably, the screening assembly includes a feeding seat, a feeding hopper, an inclined hopper plate, two guard plates, and a conveyor belt. The conveyor belt is disposed between the two guard plates. The output shaft of the brake motor is fixedly connected to the drive wheel of the conveyor belt. The inclined hopper plate is disposed on the lower side wall of the feeding hopper. A waste frame is placed on the base frame. The side wall of the feeding seat has a retrieval opening that matches the waste frame. By setting up the screening assembly, after the fruit is poured into the feeding hopper, it will slide along the side wall of the inclined hopper plate onto the conveyor belt. The debris and residual fruit in the fruit will fall into the waste frame below through the holes in the inclined hopper plate to avoid entering the packaging bag through the screening assembly and the feeding assembly, thereby reducing the defect rate of the fruit in the packaging bag.

[0008] Preferably, the feeding frame has a discharge hole on the side wall opposite to the feeding hopper, and a discharge gate is hinged inside the discharge hole. By opening the discharge hole and setting the discharge gate, the fruit that remains on the surface of the first, second, and third sieve barrels after passing through them can be removed by the staff by opening the discharge gate, thus avoiding long-term accumulation on the feeding frame and reducing the fruit feeding effect on the packaging bag.

[0009] Preferably, the inner walls of the first, second, and third feeding holes are all provided with a buffer layer, which is a sponge pad. By providing the buffer layer, during the feeding process into the packaging bag, the fruit is protected when it comes into contact with the inner walls of the first, second, and third feeding holes, thus preventing the fruit from breaking due to impact after contact with the inner walls of the first, second, and third feeding holes.

[0010] Preferably, the side wall of the feeding frame has three holes that match the No. 1, No. 2, and No. 3 screen barrels, and the end of the No. 5 shaft opposite to the No. 4 transmission wheel is rotatably connected to the inner wall of the feeding frame. By providing three holes that match the No. 1, No. 2, and No. 3 screen barrels, the No. 1, No. 2, and No. 3 screen barrels can be disassembled and replaced within the feeding frame, thus improving the service life of the feeding frame.

[0011] Preferably, the first sieve barrel has an opening on the side opposite to the second shaft, and the second and third sieve barrels also have openings on their sides. The openings of the first, second, and third sieve barrels all face the holes opposite to the sidewall of the feeding frame. By aligning the openings of the first, second, and third sieve barrels with the holes opposite to the sidewall of the feeding frame, it is possible to effectively prevent residual fruit from rolling into the holes through the openings. Furthermore, the openings of the first, second, and third sieve barrels facilitate the removal of any stuck or residual fruit.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] This invention, through the setting of a feeding assembly, allows the rotation of shaft one via a sieving mechanism after fruit residue is removed. This, in turn, drives shaft two and the first sieve barrel via a conveyor belt. Then, drive wheels one and two, via conveyor belts two, three, and four, drive sieve barrels two and three to rotate. At this point, all three sieve barrels rotate clockwise. Fruit passes sequentially through the surfaces of sieve barrels one, two, and three within the feeding frame, falling through their respective holes into the first, second, and third discharge holes. This completes the feeding process for the fruit in the packaging bags within the three collection frames, ensuring that the fruit in the packaging bags is of uniform size, resulting in a neater and more aesthetically pleasing appearance.

[0014] This utility model is achieved through the following design. Attached Figure Description

Detailed Implementation

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example 1

[0021] like Figure 1 , Figure 2 , Figure 3and Figure 4 As shown, the present invention proposes a bag feeding mechanism for a fruit packaging machine, comprising a base frame 1, a feeding assembly, and a sieving assembly. Both the sieving assembly and the feeding assembly are mounted on the base frame 1. The feeding assembly includes a brake motor 7, a feeding frame 9, a first sieve barrel 11-1, a second sieve barrel 11-2, and a third sieve barrel 11-3. The inner wall of the feeding frame 9 has a first groove 10-1, a second groove 10-2, and a third groove 10-3. The output shaft of the brake motor 7 is fixed... A first shaft 8 is fixedly connected to one end of a first screen barrel 11-1. A second shaft 12 is fixedly connected to one end of the first shaft 8 and the second shaft 12. A driving wheel and a driven wheel are respectively fixedly sleeved on the first shaft 8 and the driven wheel are connected by a first conveyor belt 13. A third shaft 14-1 is fixedly connected inside the first screen barrel 11-1. A fourth shaft 14-2 and a fifth shaft 14-3 are respectively fixedly inserted into the second screen barrel 11-2 and the third screen barrel 11-3. The third shaft 14-1 and the fourth shaft 14-2 are connected to the second screen barrel 11-3. One end of shaft 14-2 is fixedly sleeved with a first transmission wheel 20 and a second transmission wheel 21, respectively. The first transmission wheel 20 and the second transmission wheel 21 are connected by a second conveyor belt 22. The end of shaft 14-2 opposite to the second transmission wheel 21 and the end of shaft 14-3 are fixedly sleeved with a third transmission wheel 15 and a fourth transmission wheel 16, respectively. The third transmission wheel 15 and the fourth transmission wheel 16 are connected by a third transmission belt 17. The side of the feeding frame 9 The wall has a first discharge hole 18-1, a second discharge hole 18-2, and a third discharge hole 18-3. The first discharge hole 18-1, the second discharge hole 18-2, and the third discharge hole 18-3 are connected to the first trough 10-1, the second trough 10-2, and the third trough 10-3, respectively. The same collection frame is placed on the lower outer side of the first discharge hole 18-1, the second discharge hole 18-2, and the third discharge hole 18-3. Packaging bags are placed in the three collection frames.

[0022] The working principle of the bag feeding mechanism for a fruit packaging machine based on Embodiment 1 is as follows: After the residual fruit debris in the fruit is removed by the screening mechanism, the brake motor 7 can be started to rotate the first shaft 8, which in turn drives the second shaft 12 and the first screen barrel 11-1 to rotate via the first conveyor belt 13. Then, the first drive wheel 20 and the second drive wheel 21, via the second conveyor belt 22, the third drive wheel 15, and the fourth drive wheel 16, via 17, respectively drive the second screen barrel 11-2 and the third screen barrel 11-3 to rotate. At this time, one... Screen 11-1, Screen 2-2, and Screen 3-3 all rotate clockwise. The fruit passes through the surfaces of Screen 1-1, Screen 2-2, and Screen 3-3 in sequence within the feeding frame 9 and falls into the discharge holes 18-1, 18-2, and 18-3 through their different holes. This completes the feeding process of the fruit in the packaging bags in the three collection frames, making the fruit in the packaging bags the same size, more neat and beautiful. Example 2

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the present invention proposes a bag feeding mechanism for a fruit packaging machine. Compared with Embodiment 1, this embodiment further includes: a screening component including a feeding seat 2, a feeding hopper 3, an inclined hopper plate 4, two guard plates 5, and a conveyor belt 6. The conveyor belt 6 is disposed between the two guard plates 5. The output shaft of the brake motor 7 is fixedly connected to the drive wheel of the conveyor belt 6. The inclined hopper plate 4 is disposed on the lower side wall of the feeding hopper 3. A waste frame 19 is placed on the base frame 1. The side wall of the feeding seat 2 is provided with a pick-up opening that matches the waste frame 19.

[0024] In this embodiment, as Figure 2 As shown, after the fruit is poured into the feed hopper 3 of the screening component, it slides along the side wall of the inclined hopper plate 4 onto the conveyor belt 6. The debris and residual fruit in the fruit will fall from the holes of the inclined hopper plate 4 into the waste frame 19 below to avoid entering the packaging bag through the screening component and the feeding component, thereby reducing the defect rate of the fruit fed into the packaging bag.

[0025] The above specific embodiments are merely several preferred embodiments of this utility model.
