Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and in particular to a packaging machine with weighing function. Background Technology

[0002] Packaging machines are a type of machine used to package products, serving to protect and enhance their appearance. There are many types of packaging machines, and they can be classified in many ways. From different perspectives, they can be categorized by type of machine: liquid packaging machines, powder packaging machines, granule packaging machines, skin packaging machines, sauce packaging machines, electronic combination scale packaging machines, and pillow packaging machines.

[0003] A search revealed that CN217227976U discloses a packaging machine with weighing function. This utility model relates to the field of packaging machine technology. The packaging machine with weighing function includes a machine casing, a feeding hopper, and a packaging end. The feeding hopper is located at the upper part of the front surface of the machine casing, and the packaging end is located at the upper part of the middle of the front surface of the machine casing. A conveying component is provided at the front end of the machine casing, which includes a conveying frame, a first conveyor belt, and a second conveyor belt. The conveying component is used to transport and convey the packaging boxes. There are two conveying frames, which are respectively fixed on the left and right sides of the front end of the machine casing. The beneficial effect of this utility model is that, through the combination of a pull rod, a limiting block, a limiting groove, a sealing block, and a spring, the gap between the sealing block and the feeding pipe can be controlled by pulling the pull rod, which makes it easier for users to control the amount of material falling. This solves the problem that in the past, packaging machines had problems such as too much or too little material being injected, making it difficult to effectively control the amount of material injected.

[0004] When this technical solution is used, the staff needs to observe the quality of the material falling into the packaging box. When the required quality is reached, the staff stops the material feeding by moving the sealing block. This method requires the staff to observe and operate the material feeding and stopping in real time during packaging, which is very inconvenient and affects the degree of automation of packaging.

[0005] Therefore, we propose a packaging machine with weighing function. Utility Model Content

[0030] Example 1: A packaging machine with weighing function, such as Figure 1 , Figure 2 and Figure 3 As shown, including

[0031] The chassis 1 is equipped with a placement platform 4, a packaging end 5, a display 6, and a feeding hopper 7. The chassis 1 also includes a motor 9 for driving the placement platform 4, a transmission gear 10, a transmission block 11, and a rotating rod 12. A first conveyor belt 2 and a second conveyor belt 3 are located at both ends of the chassis 1 for conveying (the placement platform 4 is located in the middle of the outer wall of the chassis 1; the first and second conveyor belts 2 and 3 are located at opposite ends of the placement platform 4; the packaging end 5 is located at the top of the placement platform 4; the feeding hopper 7 is located on the outer wall of the chassis 1 at the top of the packaging end 5; the display 6 is located on one side of the outer wall of the chassis 1; a rotating rod 12 is fixedly connected to one side of the placement platform 4 and rotatably connected to the outer wall of the chassis 1; the motor 9 is fixedly connected to the outer wall of the chassis 1 via a motor frame; and the output end of the motor 9 is equipped with a transmission gear 10. The drive gear 10 and the outer wall of the placement platform 4 away from the rotating rod 12 are provided with an arc-shaped transmission block 11. The transmission block 11 meshes with the outer wall of the drive gear 10. The motor 9 is connected to the display 6 in the same channel via an electrical signal. (The part in parentheses is prior art.) When packaging is required, the packaging box is transported to the top of the placement platform 4 by the first conveyor belt 2. At this time, the material is dropped into the packaging box at the top of the placement platform 4 by the feeding hopper 7. When the material reaches the set mass, the packaging box is packaged by the packaging end 5. The display 6 drives the motor 9 to start and drive the drive gear 10 to rotate. The drive gear 10 can then drive the transmission block 11 meshing with it to rotate. The rotating rod 12 can then drive the placement platform 4 to turn to the second conveyor belt 3 and fall onto the second conveyor belt 3 by gravity for transportation.

[0032] Feeder 8 is located on the outer wall of the machine casing 1 and between the feeding hopper 7 and the packaging end 5. A rotating assembly is provided inside the feeder 8, which includes a rotating shaft 13, a rotating block 14 and a partition plate 15.

[0033] The lifting structure is located between two adjacent partition plates 15. The lifting structure includes a support plate 16, a trigger switch 18, and a reset spring 19.

[0034] like Figure 3 and Figure 4As shown, the feeder 8 has an inlet and an outlet at the top and bottom, respectively. The inlet is connected to the bottom of the feeding hopper 7, and the outlet is located at the top of the placement platform 4. The rotating shaft 13 is axially connected to the inner wall of the feeder 8 via a second motor. The second motor is connected to the display 6 in the same channel via an electrical signal. The rotating block 14 has a square cross-section and is fixedly connected to the outer wall of the rotating shaft 13. The partition plate 15 is located at both ends of the outer wall of the four sides of the rotating block 14. The other side of the partition plate 15 is attached to the inner wall of the feeder 8. The two sets of partition plates 15 located at the top and bottom are located on both sides of the inlet and outlet.

[0035] The support plate 16 is slidably connected to the opposite walls of two adjacent partition plates 15. A telescopic rod 17 is provided at the bottom of the support plate 16. The telescopic rod 17 has a fixed end and an extended end. The fixed end is fixedly connected to the outer wall of the rotating block 14. The extended end is slidably connected to the inner wall of the fixed end and fixedly connected to the bottom outer wall of the support plate 16. A return spring 19 is fixedly connected to the opposite walls of the rotating block 14 and the support plate 16. The return spring 19 is sleeved on the outer wall of the telescopic rod 17.

[0036] When material is fed into the hopper 7, it falls into the top support plate 16 through the feed port at the top of the feeder 8. The material falls into the support plate 16 and squeezes it. The bottom return spring 19 is squeezed and retracts, which drives the telescopic rod 17 to retract synchronously.

[0037] like Figure 4 As shown, the trigger switch 18 is located at the fixed end of the telescopic rod 17 near the rotating block 14, and the trigger switch 18 is connected to the second motor in the same path.

[0038] When the telescopic rod 17 retracts to a certain extent, the extended end of the telescopic rod 17 presses against the trigger switch 18. The trigger switch 18, when pressed, will start the second motor. The start of the second motor will cause the rotating shaft 13 to rotate 90 degrees, rotating the support plate 16 containing the material to the side wall. At this time, the material falls back onto the top support plate 16. The second motor can then be started again to rotate the rotating shaft 13, rotating the support plate 16 containing the material to the bottom position. The material can then fall into the packaging box on the top of the placement platform 4 through the discharge port by gravity.

[0039] In summary, by using the feeder 8 and lifting structure, when the material quality reaches the threshold, the second motor can be started by squeezing the trigger switch 18, which in turn drives the rotating shaft 13 and the rotating block 14 and the partition plate 15 on it to rotate and unload the material. This eliminates the need for staff to operate the loading and unloading of the material, thus improving the automation level of packaging.

[0040] like Figure 5As shown, scrapers 20 are provided on all four sides of the top of the bearing plate 16. The scrapers 20 are in contact with the wall of the partition plate 15, and the inner side of the cross-section of the scraper 20 is concave.

[0041] When the support plate 16 moves to unload material, the spring force of the return spring 19 drives the support plate 16 to move away from the rotating block 14, so that the concave structure of the scraper 20 on it can scrape off the material remaining at the partition plate 15.

[0042] like Figure 6 As shown, the partition plate 15 has a connected scraper groove 21 and guide groove 22 on the side near the inner wall of the feeder 8. The scraper groove 21 is concave and the guide groove 22 is convex and extends to the side wall of the partition plate 15.

[0043] When the partition plate 15 rotates, the material remaining on the inner wall of the feeder 8 can be scraped off by the concave shape of the scraper groove 21 and guided to the bearing plate 16 by the guide groove 22, and then rotated to the bottom with the bearing plate 16 for feeding.

[0044] The scraper 20, scraper groove 21 and guide groove 22 can scrape off the material remaining on the walls of the separator 15 and feeder 8, preventing material retention from affecting the accuracy of its quality and packaging.

[0045] Example 2: Based on Example 1, with reference to Figure 7 A threaded rod 23 is fixedly connected to the middle position of the bearing plate 16, and a threaded groove is opened in the counterweight block 24. The counterweight block 24 is threadedly connected to the outer wall of the threaded rod 23.

[0046] When it is necessary to change the threshold of the material quality, simply screw the counterweight 24 to be modified onto the threaded rod 23. The counterweight 24 will then compress the return spring 19 to produce a certain amount of deformation, thereby retracting the telescopic rod 17 to change the threshold of compressing the trigger switch 18.

[0047] With the threaded rod 23 and counterweight 24, the weight of the material can be adjusted by simply screwing the counterweight 24 into the threaded rod 23, thus facilitating the packaging of materials of different weights and meeting actual production needs.

[0048] The working principle of this utility model is as follows: When packaging is required, the packaging box is transported to the top of the placement platform 4 via the first conveyor belt 2. At this time, when material is fed from the hopper 7, it falls into the top support plate 16 through the feed inlet at the top of the feeder 8. The material pressing against the support plate 16 causes the bottom return spring 19 to retract, simultaneously retracting the telescopic rod 17. When the telescopic rod 17 retracts to a certain extent, its extended end presses against the trigger switch 18. This pressure activates the second motor, which in turn rotates the rotating shaft 13 by ninety degrees. Rotate the material-containing support plate 16 to the side wall. At this time, the material falls back onto the top support plate 16. Then, the second motor is started again to drive the rotating shaft 13 to rotate, which will rotate the material-containing support plate 16 to the bottom position. The material will then fall into the packaging box on the top of the placement platform 4 by gravity through the discharge port. The packaging box is then packaged through the packaging end 5. The display 6 drives the motor 9 to start and drive the transmission gear 10 to rotate. The transmission gear 10 will drive the transmission block 11 meshing with it to rotate. The rotating rod 12 will drive the placement platform 4 to turn to the second conveyor belt 3, and the material will fall onto the second conveyor belt 3 by gravity for conveying.
