Description

Technical Field

[0001] This utility model belongs to the field of packaging machine technology, and in particular relates to an adaptive material metering device for vertical packaging machines. Background Technology

[0002] Vertical packaging machines are highly automated packaging equipment. Their core working principle is to use roll film (a roll of packaging film) to complete a series of actions such as bag making, metering and filling, sealing, and cutting from top to bottom on the machine frame, ultimately forming individual packaged products.

[0003] There are many types of vertical packaging machines on the market. For example, a multi-particle metering vertical packaging machine with publication number CN217598972U is disclosed on the China Patent Network. This type of vertical packaging machine has a metering function, but there are some defects and deficiencies that need to be improved: (1) When packaging materials, the vertical packaging machine needs to meter the materials so that a large amount of bulk materials can be accurately divided and introduced into each independent packaging bag according to a pre-set, uniform weight or volume. However, due to the structural design of some existing vertical packaging machine metering devices, most of them require manual adjustment of the metering device parameters, which is not only time-consuming and labor-intensive, but also has low efficiency. At the same time, it requires a high level of technical skills from the staff, and it is often difficult to guarantee the accuracy of the metering, thus leading to errors; (2) Some existing vertical packaging machine metering devices lack diversion measures. When the amount of material is large, it is easy to accumulate together and cause blockage, thus affecting the subsequent material metering and packaging. Therefore, in view of the above problems, the adaptive material metering device for vertical packaging machines provided by this utility model is of great significance. Utility Model Content

[0004] This utility model provides an adaptive material metering device for a vertical packaging machine. The automatic metering mechanism can automatically meter large quantities of bulk materials and then guide the metered materials into the vertical packaging machine for automatic packaging. The entire metering process requires no manual intervention, saving time and effort while avoiding errors caused by manual metering. Multiple diversion channels can divert the materials, allowing them to enter their respective guide channels, effectively preventing material accumulation and blockage. In summary, this invention solves the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] The adaptive material metering device for a vertical packaging machine of this utility model includes a guide platform, which is an isosceles trapezoid with an inclined top. A pair of mounting brackets are fixedly connected to the bottom of the guide platform, and mounting holes are opened at both ends of the mounting brackets. A support and a discharge bin are fixedly connected to both ends of the guide platform, respectively. A feeding hopper is installed on the support. A guide trough is fixedly connected to the top of the guide platform and is located directly below the feeding hopper. Several first partitions are fixedly connected to the bottom of the trough, and the first partitions divide the interior of the guide trough into several diversion channels. Fixed seats are fixedly connected to both outer walls of the discharge bin, and guide holes are opened on the fixed seats. Several second partitions are fixedly connected to the inner wall of the discharge bin, and the second partitions divide the interior of the discharge bin into several guide channels. An automatic metering mechanism is provided in the discharge bin, and several discharge ports are opened at the bottom of the discharge bin, with a discharge hopper fixedly connected to each discharge port.

[0007] The automatic metering mechanism includes a lifting plate, with guide rods fixedly connected to both ends of the top of the lifting plate. The diameter of the guide rod is equal to the diameter of the guide hole, and its top end passes through the corresponding guide hole and is provided with a protrusion. A spring is wound around the body of the guide rod, and the top and bottom ends of the spring are fixedly connected to the bottom of the fixed base and the top of the lifting plate, respectively. Several metering slots are fixedly connected to the top of the lifting plate. The metering slots are located in each material guide channel, and each metering slot has a material guide opening at its top.

[0008] Furthermore, the mounting bracket has L-shaped ends, and reinforcing blocks are fixedly connected between the inner walls on both sides and the bottom surface. The reinforcing blocks are triangular.

[0009] Furthermore, the support is C-shaped, with several insertion holes on its top. The insertion holes are square holes.

[0027] Please see Figure 1-5As shown, the adaptive material metering device for a vertical packaging machine of this utility model includes a guide platform 1, which is an isosceles trapezoid with an inclined top. A pair of mounting brackets 2 are fixedly connected to the bottom of the guide platform 1. Mounting holes 3 are provided at both ends of the mounting brackets 2, into which fasteners such as bolts can be inserted to fix the metering device in a suitable position on the vertical packaging machine. A bracket 4 and a discharge bin 5 are fixedly connected to both ends of the guide platform 1, respectively. A feed hopper 6 is installed on the bracket 4. A guide trough 7 is fixedly connected to the top of the guide platform 1, located directly below the feed hopper 6. Several first partitions 8 are fixedly connected to the bottom of the trough, and the first partitions 8 divide the interior of the guide trough 7. The material is divided into several diversion channels 9. A large batch of bulk materials to be packaged can be introduced into the guide channel 7 through the feeding hopper 6. After entering the guide channel 7, the material can slide down along the guide channel 7. The outer walls on both sides of the discharge bin 5 are fixedly connected with fixed seats 10. The fixed seats 10 are provided with guide holes 11. The inner wall of the discharge bin 5 is fixedly connected with several second partitions 12. The second partitions 12 divide the interior of the discharge bin 5 into several guide channels 13. After sliding down along the guide channel 7, the material can enter each guide channel 13. The discharge bin 5 is equipped with an automatic metering mechanism, and the bottom of the discharge bin 5 is provided with several discharge ports 14. Each discharge port 14 is fixedly connected with a discharge hopper 15.

[0028] The automatic metering mechanism includes a lifting plate 16. Guide rods 17 are fixedly connected to both ends of the top of the lifting plate 16. The diameter of the guide rods 17 corresponds to the diameter of the guide holes 11. The top of each guide rod passes through the corresponding guide hole 11 and is provided with a protrusion. A spring 18 is wound around the body of the guide rod 17. The top and bottom ends of the spring 18 are fixedly connected to the bottom of the fixed base 10 and the top of the lifting plate 16, respectively. Several metering slots 19 are fixedly connected to the top of the lifting plate 16. The metering slots 19 are located within each material guide channel 13, and each metering slot 19 has a guide port 20 at its top. Material entering the material guide channel 13 can fall into the corresponding metering slot 19. As the amount of material increases, the metering slots... As the weight of metering trough 19 increases, under the influence of gravity, it will cause the lifting plate 16 to move downward and stretch the spring 18. When the weight of the material in metering trough 19 exceeds a certain level, the height of the guide port 20 on metering trough 19 will be flush with the height of the discharge port 14 on discharge bin 5. At this time, the material will be discharged through the guide port 20 and guided into the feed port of the vertical packaging machine along the discharge port 14 and discharge hopper 15. As the material in metering trough 19 gradually decreases, the weight of metering trough 19 also decreases. At this time, under the elastic reset action of spring 18, the lifting plate 16 will return to the initial position along with metering trough 19, thus completing the automatic metering of materials without manual intervention.

[0029] The mounting frame 2 has L-shaped ends, and reinforcing blocks 21 are fixedly connected between the inner walls on both sides and the bottom surface. The reinforcing blocks 21 are triangular and can support and reinforce the mounting frame 2 to improve the structural strength of the mounting frame 2, thereby preventing it from bending and deforming after being subjected to force for a long time, which would affect the installation stability of the metering device.

[0030] The support 4 is C-shaped, with several insertion holes 22 on its top. The insertion holes 22 are square holes. Several insertion blocks 23 are fixedly connected to the outer wall of the feed hopper 6. The insertion blocks 23 are L-shaped, and their width and thickness correspond to the length and width of the insertion holes 22, respectively. The center of each insertion block 23 corresponds to the center of each insertion hole 22. Each insertion block 23 can be inserted into and fit into the corresponding insertion hole 22. At this time, the feed hopper 6 can be fixed by insertion. After long-term use, the feed hopper 6 can be removed from the support 4 by pulling out the insertion blocks 23 so that the material residue adhering to the inner wall of the feed hopper 6 can be cleaned regularly.

[0031] The number of material guiding channels 13 and the diversion channels 9 are the same, and their widths are equal. The center of each material guiding channel 13 corresponds one-to-one with the center of each diversion channel 9. After the material enters the material guiding trough 7, it can slide down along the material guiding trough 7 and enter each diversion channel 9. At this time, the material can be diverted through multiple diversion channels 9. The diverted material can enter each corresponding material guiding channel 13, thereby effectively preventing the material from accumulating together and causing blockage.

[0032] The metering troughs 19 and the guiding channels 13 are both rectangular in cross-section, and the number of them is the same. The length and width of their outer walls correspond to the length and width of the guiding channels 13, respectively. The center of each metering trough 19 corresponds one-to-one with the center of each guiding channel 13. The inner wall of the top opening of each metering trough 19 is inclined downward. Each metering trough 19 can be attached to the inner wall of the corresponding guiding channel 13. When the diverted material enters each guiding channel 13, it can slide down along the inner wall of the top opening of the metering trough 19 until it falls into the metering trough 19, thereby effectively preventing the material from falling into the gap between the metering trough 19 and the guiding channel 13.

[0033] The guide port 20 and the discharge port 14 are both rectangular, with the same number and corresponding length and width. The center of each guide port 20 corresponds to the center of each discharge port 14. The guide port 20 is located above the discharge port 14. When the automatic metering mechanism moves downward as the weight of the material increases until the height of the discharge port 14 and the guide port 20 are level, each discharge port 14 can completely overlap with the corresponding guide port 20, thereby ensuring that the material in each metering tank 19 can be smoothly discharged along the corresponding discharge port 14 and discharge hopper 15.

[0034] All standard parts used in the application documents can be purchased from the market. All components in this application documents can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art.

[0035] The working principle of this utility model is as follows:

[0036] In use, this utility model allows the metering device to be fixedly installed in a suitable position on a vertical packaging machine via the mounting bracket 2, ensuring that each discharge hopper 15 is aligned with the inlet of the vertical packaging machine. Then, the large batch of bulk material to be packaged is guided into the guide trough 7 through the feed hopper 6. After entering the guide trough 7, the material slides downwards along the guide trough 7 and enters each diversion channel 9. At this point, the material is diverted through multiple diversion channels 9, and the diverted material enters its corresponding guide channel 13, effectively preventing material from accumulating and causing blockage. The material entering the guide channel 13 falls into the corresponding metering trough 19. As the amount of material increases, the weight of the metering trough 19 continuously increases. Under the action of gravity, the metering tank 19 will drive the lifting plate 16 to move downward and stretch the spring 18. When the weight of the material in the metering tank 19 exceeds a certain level, the height of the guide port 20 on the metering tank 19 will be flush with the height of the discharge port 14 on the discharge bin 5. At this time, the material will be discharged through the guide port 20 and introduced into the feed port of the vertical packaging machine along the discharge port 14 and the discharge hopper 15. Then, the vertical packaging machine can automatically package the metered material. As the material in the metering tank 19 gradually decreases, the weight of the metering tank 19 also decreases. At this time, under the elastic reset action of the spring 18, the lifting plate 16 will return to the initial position along with the metering tank 19, so that the automatic metering of the material can be completed without manual intervention.

[0037] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.

This utility model is limited only by the claims and their full scope and equivalents.
