Description

Technical Field

[0001] This utility model relates to the field of automatic weighing, counting and packaging machine technology, and in particular to an automatic weighing, counting and packaging machine with a slow feeding control structure. Background Technology

[0002] Automatic weighing and counting packaging machines are highly efficient devices that integrate precision weighing, automatic counting, and packaging. They play an important role in modern industrial production. The weighing hopper is equipped with a high-precision weighing sensor that monitors the weight of the material in real time and transmits the data to the control system. The control system calculates based on the preset quantitative value to ensure the accuracy of each weighing. When the material weight reaches the preset value, the control system records the quantity of the material and performs accurate counting. The weighed and counted material then enters the packaging bag or container.

[0003] However, traditional automatic weighing and counting packaging machines often rely on vibration devices to achieve the uniform falling and stacking of plastic pads during the feeding process. Although this method is simple and direct, vibration feeding can easily cause the plastic pads to clump together, making it difficult to accurately control the amount of material fed each time, thus affecting the subsequent weighing and counting accuracy.

[0004] For example, when plastic pads are being weighed, the vibration device may cause some plastic pads to continue to be fed, resulting in accumulation and affecting the accuracy of the weighing. At the same time, since the number of plastic pads is difficult to control, workers often need to manually adjust or perform secondary screening, which greatly increases labor intensity and time costs. Utility Model Content

[0005] This utility model discloses an automatic weighing and counting packaging machine with a slow feeding control structure. It aims to solve the technical problem that traditional automatic weighing and counting packaging machines often rely on vibration devices to achieve uniform falling and stacking of plastic pads in the feeding stage. Although this method is simple and direct, vibration feeding can easily cause plastic pads to clump together, making it difficult to accurately control the amount of each feeding, thus affecting the subsequent weighing and counting accuracy.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic weighing, counting, and packaging machine with a slow-speed feeding control structure includes a mounting frame and a support frame. The top outer wall of the mounting frame is equipped with a conveyor belt, and the top of the support frame is equipped with a feeding hopper. The machine further includes: a quantitative feeding mechanism located at the bottom of the feeding hopper; the quantitative feeding mechanism includes a fixed frame; an electric telescopic rod is provided on the inner wall of one side of the fixed frame; a baffle is fixedly connected to the movable end of the electric telescopic rod; a connecting plate is hinged to one side of the outer wall of the baffle; five mounting slots are opened on the top outer wall of the connecting plate; the baffle is slidably connected to the inner wall of the opposite side of the fixed frame; a limiting plate is provided on the inner wall of the opposite side of the fixed frame; a feeding cylinder is provided on the bottom outer wall of the feeding hopper; the feeding hopper communicates with the feeding cylinder; five fixing openings are opened on the bottom outer wall of the feeding cylinder, and the fixing openings correspond to the positions of the mounting slots; and a driving mechanism located inside the feeding hopper.

[0008] The above technical solution can control the amount of plastic pads being fed. Compared with the traditional method of relying on vibration to pile up the pads, it improves the accuracy of weighing and counting, and reduces the workload of workers. Specifically, during use, the plastic pads are conveyed into the hopper by a conveyor belt. Then, the drive mechanism rotates and pushes the plastic pads that have fallen into the hopper, so that some of the plastic pads fall into the mounting slot. Then, the movable end of the electric telescopic rod drives the baffle and connecting plate to move forward under the limit of the fixed frame. At this time, the baffle will replace the position of the connecting plate to block the fixing port at the bottom of the hopper. When the connecting plate is completely closed... When the connecting plate extends beyond the support range of the limiting plate, it will rotate and fall due to its own gravity, thus forming a 90-degree angle with the baffle. Then, the plastic pads on the mounting slot will automatically fall into the collection tray, where they will be automatically weighed and counted by an electronic scale. Based on the measurement results of the electronic scale, the equipment can automatically calculate the number of plastic pads and perform subsequent packaging work. When the movable end of the electric telescopic rod drives the baffle and connecting plate to retract, the connecting plate will fall back onto the upper surface of the limiting plate, and the mounting slot on the connecting plate will correspond to the fixed opening on the feeding cylinder, waiting for the drive mechanism to push multiple plastic pads to fall in for the next time.

[0009] In a preferred embodiment, the driving mechanism includes a connecting block, a fixing groove is formed on the bottom outer wall of the connecting block, a motor is provided on the inner wall of the fixing groove, a connecting rod is fixedly connected to the output shaft of the motor, a fixing frame is provided on the circumferential inner wall of the feeding cylinder, one end of the connecting rod is connected to the bottom inner wall of the feeding cylinder through a bearing, limiting frames are provided on both sides of the outer wall of the connecting block, one end of the limiting frame is fixedly connected to the circumferential inner wall of the feeding cylinder, and a scraper is provided on the circumferential outer wall of the connecting rod, the scraper dividing the internal space of the feeding cylinder into two.

[0010] In this design, plastic pads are placed in the placement slot of the conveyor belt and transported into the hopper by the movement of the conveyor belt. When feeding is required, the motor starts, driving the connecting rod to rotate via the output shaft. As the connecting rod rotates, a scraper continuously scrapes the inner wall of the feeding cylinder, pushing the plastic pads from one side to the other. Simultaneously, the scraper prevents the plastic pads from accumulating or getting stuck in the feeding cylinder, ensuring even distribution of the pads within the cylinder. When the connecting rod rotates to a certain position, some plastic pads fall through the fixed opening at the bottom of the feeding cylinder into the mounting slot of the connecting plate of the quantitative feeding mechanism. This device can precisely control the feeding amount, prevent the plastic pads from accumulating or getting stuck in the feeding cylinder, reduce manual operation by workers, and lower labor intensity.

[0011] In a preferred embodiment, the outer circumferential wall of the feeding cylinder is provided with an installation port, and the inner wall of the installation port is provided with five equally spaced slots and four partition plates. The partition plates separate two adjacent slots, and the slots are connected to the installation slot.

[0012] In this solution, the user can change the feeding amount by adjusting the number of fixed ports on the feeding cylinder according to the actual weighing and metering needs. For example, the number of fixed ports can be controlled by inserting a plate into the slot to block the fixed ports. This design makes the equipment highly flexible and can adapt to plastic pads with different weighing requirements, as well as different production and packaging requirements.

[0013] As described above, an automatic weighing, counting, and packaging machine with a slow-speed feeding control structure includes a mounting frame and a support frame. The top outer wall of the mounting frame is equipped with a conveyor belt, and the top of the support frame is equipped with a feeding hopper. The machine also includes: a quantitative feeding mechanism located at the bottom of the feeding hopper; the quantitative feeding mechanism includes a fixed frame; an electric telescopic rod is provided on the inner wall of one side of the fixed frame; a baffle is fixedly connected to the movable end of the electric telescopic rod; a connecting plate is hinged to one side of the baffle; five mounting slots are opened on the top outer wall of the connecting plate; the baffle is slidably connected to the inner wall of the opposite side of the fixed frame; a limiting plate is provided on the inner wall of the opposite side of the fixed frame; a feeding cylinder is provided on the bottom outer wall of the feeding hopper; the feeding hopper communicates with the feeding cylinder; five fixing ports are opened on the bottom outer wall of the feeding cylinder; the fixing ports correspond to the positions of the mounting slots; and a driving mechanism located inside the feeding hopper. The automatic weighing and counting packaging machine with a slow feeding control structure provided by this utility model can control the feeding amount of plastic pads. Compared with the traditional method of feeding by vibration and piling, it improves the accuracy of weighing and counting and reduces the workload of workers. Attached Figure Description

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0021] The automatic weighing and counting packaging machine with a slow feeding control structure disclosed in this utility model is mainly used in scenarios where traditional automatic weighing and counting packaging machines often rely on vibration devices to achieve uniform falling and stacking of plastic pads during the feeding process. Although this method is simple and direct, vibration feeding can easily cause the plastic pads to clump together, making it difficult to accurately control the amount of material fed each time, thus affecting the subsequent weighing and counting accuracy.

[0022] Reference Figure 1 and Figure 2An automatic weighing and counting packaging machine with a slow-speed feeding control structure includes a mounting frame 1 and a support frame 5. The top outer wall of the mounting frame 1 is provided with a conveyor belt 2, and the top of the support frame 5 is provided with a feeding hopper 4. The machine also includes: a quantitative feeding mechanism located at the bottom of the feeding hopper 4, which includes a fixed frame 11. An electric telescopic rod 12 is provided on the inner wall of one side of the fixed frame 11. A baffle 14 is fixedly connected to the movable end of the electric telescopic rod 12. A connecting plate 15 is hinged to one side of the outer wall of the baffle 14. Five mounting slots 16 are opened on the top outer wall of the connecting plate 15. The baffle 14 is slidably connected to the inner wall of the opposite side of the fixed frame 11. A limiting plate 17 is provided on the inner wall of the opposite side of the fixed frame 11. A feeding cylinder 10 is provided on the bottom outer wall of the feeding hopper 4. The feeding hopper 4 communicates with the feeding cylinder 10. Five fixing ports are opened on the bottom outer wall of the feeding cylinder 10, and the fixing ports correspond to the positions of the mounting slots 16. A drive mechanism is located inside the feeding hopper 4.

[0023] The outer wall of the conveyor belt 2 is provided with several equally spaced partitions 3. Two adjacent partitions 3 form a placement slot. The plastic pads are placed in the placement slot of the conveyor belt 2 and transported to the inside of the hopper 4 by the movement of the conveyor belt 2. Since each placement slot is composed of two adjacent partitions 3, each plastic pad is placed and transported separately, avoiding stacking or confusion.

[0024] In the specific implementation process, both the connecting plate 15 and the limiting plate 17 are arc-shaped structures, and the positions of the connecting plate 15 and the limiting plate 17 correspond. The connecting plate 15 is set to be arc-shaped mainly to correspond to the distribution position of the five mounting ports 13, and the limiting plate 17 is set to be arc-shaped to facilitate the support of the connecting plate 15.

[0025] Among them, a support plate 6 is fixedly connected to one side of the outer wall of the support frame 5, and an electronic scale 7 is provided on the top outer wall of the support plate 6. A collection tray 8 is provided on the top outer wall of the electronic scale 7. The electronic scale 7 is used to accurately measure the weight of the plastic pads falling into the collection tray 8, thereby realizing the automatic weighing function.

[0026] Specifically, in use, the plastic gaskets are conveyed to the inside of the hopper 4 via the conveyor belt 2. Then, the drive mechanism rotates and pushes the plastic gaskets that have fallen into the hopper 10, causing some of the plastic gaskets to fall into the mounting slot 16. Then, the movable end of the electric telescopic rod 12 drives the baffle 14 and the connecting plate 15 to move forward under the limitation of the fixed frame 11. At this time, the baffle 14 will replace the position of the connecting plate 15 to block the fixed opening at the bottom of the hopper 10. When the connecting plate 15 is fully extended beyond the support range of the limiting plate 17, the connecting plate 15 will rotate and fall due to its own gravity, thus forming a 90-degree angle with the baffle 14. Then, the mounting slot 16... The plastic pads will automatically fall into the collection tray 8, and the electronic scale 7 will automatically weigh and count them. Based on the measurement results of the electronic scale 7, the equipment can automatically calculate the number of plastic pads and carry out subsequent packaging work. When the movable end of the electric telescopic rod 12 drives the baffle 14 and the connecting plate 15 to retract, the connecting plate 15 will fall again on the upper surface of the limiting plate 17, and the mounting groove 16 on the connecting plate 15 corresponds to the fixed port position on the feeding cylinder 10, waiting for the drive mechanism to push multiple plastic pads to fall in for the next time. This device can control the amount of plastic pads fed, which improves the accuracy of weighing and counting and reduces the workload of workers compared with the traditional method of feeding by vibration and piling.

[0027] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 In a preferred embodiment, the driving mechanism includes a connecting block, a fixing groove is provided on the bottom outer wall of the connecting block, a motor is provided on the inner wall of the fixing groove, a connecting rod 19 is fixedly connected to the output shaft of the motor, a fixing frame is provided on the circumferential inner wall of the feeding cylinder 10, one end of the connecting rod 19 is connected to the bottom inner wall of the feeding cylinder 10 through a bearing, a limiting frame is provided on both sides of the outer wall of the connecting block, one end of the limiting frame is fixedly connected to the circumferential inner wall of the feeding cylinder 10, and a scraper 18 is provided on the circumferential outer wall of the connecting rod 19, the scraper 18 divides the internal space of the feeding cylinder 10 into two.

[0028] It should be noted that the connecting block is attached Figure 3 and attached Figure 4 As can be seen, the mounting slot and motor are not shown in the attached diagram due to obstruction, but according to the attached diagram... Figure 3 and attached Figure 4 The exact location can be deduced.

[0029] The scraper 18 has a stop 9 on its top outer wall. The stop 9 covers the outer circumference of the connecting block. When the motor starts and drives the connecting rod 19 to rotate, the scraper 18 can push multiple plastic pads to rotate inside the feed cylinder 10. At this time, the stop 9 not only protects the connecting block, but also ensures that the plastic pads are more effectively distributed and pushed out. Under the combined action of the scraper 18 and the stop 9, the plastic pads are scraped and pushed evenly to the outlet position of the feed cylinder 10. When the connecting rod 19 rotates to a certain angle, the plastic pads fall into the mounting groove 16 through the fixing port at the bottom of the feed cylinder 10.

[0030] In practical use, the outer circumferential wall of the feeding cylinder 10 is provided with an installation port 13. The inner wall of the installation port 13 is provided with five equally spaced slots and four partition plates. The partition plates separate two adjacent slots. The slots are connected to the installation groove 16. According to the actual weighing and metering needs, the user can change the feeding amount by adjusting the number of fixed ports on the feeding cylinder 10. For example, the number of fixed ports can be controlled by inserting a plate into the slot to block the fixed port. This design makes the equipment highly flexible and can adapt to plastic pads with different weighing requirements, as well as different production and packaging requirements.

[0031] Specifically, the plastic pads are placed in the placement groove of the conveyor belt 2 and transported to the inside of the feeding hopper 4 by the movement of the conveyor belt 2. When feeding is required, the motor starts and drives the connecting rod 19 to rotate through the output shaft. As the connecting rod 19 rotates, the scraper 18 continuously scrapes the inner wall of the feeding cylinder 10, pushing the plastic pads from one side of the feeding cylinder 10 to the other side. At the same time, the scraper 18 also prevents the plastic pads from accumulating or getting stuck in the feeding cylinder 10. Under the action of the scraper 18, the plastic pads are evenly distributed in the feeding cylinder 10. When the connecting rod 19 rotates to a certain position, some of the plastic pads will fall into the mounting groove 16 of the connecting plate 15 of the quantitative feeding mechanism through the fixed opening at the bottom of the feeding cylinder 10. This device can accurately control the feeding amount, prevent the plastic pads from accumulating or getting stuck in the feeding cylinder 10, reduce manual operation by workers, and reduce labor intensity.

[0032] Working principle: During use, the plastic pads are conveyed into the hopper 4 via the conveyor belt 2. Then, the drive mechanism rotates and pushes the plastic pads that have fallen into the discharge cylinder 10, causing some of the plastic pads to fall into the mounting groove 16. Then, the movable end of the electric telescopic rod 12 drives the baffle 14 and the connecting plate 15 to move forward under the limitation of the fixed frame 11. At this time, the baffle 14 will replace the position of the connecting plate 15 to block the fixed opening at the bottom of the discharge cylinder 10. When the connecting plate 15 is fully extended beyond the support range of the limiting plate 17, the connecting plate 15 will rotate and fall due to its own gravity. This creates a 90-degree angle with the baffle 14. The plastic pads on the mounting groove 16 then automatically fall into the collection tray 8. The electronic scale 7 automatically weighs and counts the plastic pads. Based on the measurement results of the electronic scale 7, the equipment can automatically calculate the number of plastic pads and perform subsequent packaging work. When the movable end of the electric telescopic rod 12 drives the baffle 14 and the connecting plate 15 to retract, the connecting plate 15 will fall again on the upper surface of the limiting plate 17. The mounting groove 16 on the connecting plate 15 corresponds to the fixed opening on the feeding cylinder 10, waiting for the drive mechanism to push multiple plastic pads to fall in for the next time.

[0033] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
