Abstract
Description
Technical Field
[0001] This utility model relates to the field of bag making machine technology, specifically to an intermittent feeding mechanism for granules in a bag making machine. Background Technology
[0002] A bag-making machine is a machine that produces various plastic or other material packaging bags. Its processing range includes packaging bags of various sizes, thicknesses, and specifications made of plastic or other materials, with plastic packaging bags being the main product.
[0003] During the use of a bag-making machine, it is necessary to feed material into the hopper inside the machine. Currently, the feeding is usually done manually by pouring the plastic granules into the hopper. The hopper is connected to the inside of the bag-making machine. After the whole bag of products is poured in, the melting chamber of the bag-making machine will melt the plastic granules and perform injection molding to form a plastic bag.
[0004] In the current bag-making machine's feeding operation, the lack of a quantitative feeding control function in the hopper causes plastic particles to clog the melting chamber during the feeding process, which in turn affects the melting efficiency of the plastic particles. Furthermore, loading a large amount of plastic particles into the injection molding machine will leave a significant amount of unused molten plastic particles and unmelted plastic particles stuck in the hopper after processing. Cleaning these residual impurities is time-consuming and labor-intensive. Therefore, the feeding section of the existing bag-making machine has the problem of being unable to quantitatively feed the material. Utility Model Content
[0005] The purpose of this invention is to set up an adjustable feeding component that can magnetically induct the feeding opening based on the weight of the material, allowing for the feeding of a specific weight and controlling the feeding rhythm, thereby quantitatively feeding plastic particles.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an intermittent feeding mechanism for granules in a bag-making machine, comprising a feeding mounting base, wherein a feeding port is provided on the feeding mounting base, and an adjusting feeding component is slidably disposed on the feeding mounting base. The adjusting feeding component includes several vertical sliding columns fixedly connected to the surface of the feeding mounting base, each vertical sliding column having a vertical sliding groove. The adjusting feeding component further includes an upper feeding hopper and a lower feeding hopper disposed below the upper feeding hopper, wherein a lower feeding hopper is provided with a lower feeding feed. The lower feed hopper is slidably connected within the vertical slide groove. A sealing plate is slidably connected to the bottom surface of the lower feed hopper. A driving assembly for driving the sealing plate to slide is provided on one side of the lower feed hopper. The driving assembly includes a driving cylinder. A Hall switch is fixedly provided on one side of the upper feed hopper. A magnetic component matching the Hall switch is fixedly connected to the feed mounting base. The Hall switch controls the driving cylinder. A reset spring for pushing the lower feed hopper away from the top surface of the feed mounting base is fixedly connected within the slide rail.
[0007] Preferably, the drive assembly further includes a drive support plate fixedly connected to the drive cylinder. The drive support plate and the side wall of the lower feed hopper are riveted together by a connecting rod. A rotating block is fixedly connected to the piston rod end of the drive cylinder. A shaped plate is rotatably connected to one side of the rotating block. An extension block is fixedly connected to the side wall of the lower feed hopper. The shaped plate and the extension block are rotatably connected. A drive shaft extends from the surface of the shaped plate. A horizontal sliding block is slidably connected to one end of the drive shaft. The horizontal sliding block is fixedly connected to the surface of the closing plate.
[0008] Preferably, the horizontal sliding block is provided with a driving groove, and the driving shaft slides within the driving groove.
[0009] Preferably, a horizontal slide bar extends from one side of the feed hopper, and the horizontal sliding block is slidably connected to the horizontal slide bar.
[0010] Preferably, a partition plate opposite to the bottom surface of the upper feed hopper is fixedly connected inside the cavity of the lower feed hopper, and a telescopic rod is fixedly connected to the partition plate, with the telescopic end of the telescopic rod fixedly connected to the bottom surface of the upper feed hopper.
[0011] Preferably, the telescopic rod is provided with a telescopic groove, and a fixing nut for fixing the output end of the telescopic rod is threaded into the telescopic groove.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. An adjustable feeding component is installed to adjust the feeding. Gravity causes the Hall switch on the feeding hopper to move closer to the magnetic component below. Feeding only occurs when the switch moves closer. Gravity controls the amount of feed, achieving an intermittent feeding effect.
[0014] 2. A drive component is installed that can drive the bottom sealing plate of the hopper through a cylinder. The sealing plate is linked with a Hall switch to switch between closed and open states, further improving the intermittent feeding effect. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.
[0025] refer to Figure 1-5 A feeding mounting base 1 is provided, and a feeding port 11 is opened on the feeding mounting base 1. The feeding port 11 is connected to the inside of the bag making machine. The feeding mounting base 1 is installed at the feeding point of the bag making machine and can be disassembled and replaced.
[0026] refer to Figure 1-5 An adjustable feeding assembly 2 is slidably mounted on the feeding mounting base 1. The adjustable feeding assembly 2 includes several vertical sliding columns 21 fixedly connected to the surface of the feeding mounting base 1. Each vertical sliding column 21 has a vertical sliding groove 211. The adjustable feeding assembly 2 also includes an upper feeding hopper 22 and a lower feeding hopper 23 located below the upper feeding hopper 22. The upper feeding hopper 22 and the lower feeding hopper 23 move along the length of the vertical sliding columns 21. The lower feeding hopper 23 is provided with a lower feeding port 231. The hopper 23 is slidably connected in the vertical slide groove 211. A sealing plate 232 is slidably connected to the bottom surface of the feed inlet 231 to close it when no feeding is needed and to increase the overall weight of the feed hopper 23. A return spring 212 is fixedly connected in the vertical slide groove 211 to push the feed hopper 23 away from the top surface of the feed mounting seat 1. When the feed particles in the feed hopper 23 are discharged, the weight at the feed hopper 23 is lower than the elastic force of the return spring 212, and it will be reset by the return spring 212.
[0027] refer to Figure 1-5A drive assembly 3 for sliding the closing plate 232 is provided on one side of the lower feed hopper 23. The drive assembly 3 includes a drive cylinder 31, which controls the opening and closing of the closing plate 232. A Hall switch 221 is fixedly provided on one side of the upper feed hopper 22. A magnetic component 12 matching the Hall switch 221 is fixedly connected to the feed mounting base 1. The Hall switch 221 controls the drive cylinder 31. The Hall switch 221 is activated by the magnetic component 12, which in turn controls the movement of the drive cylinder 31. The drive assembly 3 also includes a drive support plate 32 fixedly connected to the drive cylinder 31. The drive support plate 32 and the side wall of the lower feed hopper 23 are riveted together by a connecting rod. A rotating block 34 is fixedly connected to the piston rod end of the drive cylinder 31. One side of the rotating block 34 is rotatably connected to... The hopper 23 has a shaped plate and an extension block 36 fixedly connected to the side wall. The shaped plate and the extension block 36 are rotatably connected. A drive shaft 361 extends from the surface of the shaped plate. A horizontal sliding block is slidably connected to one end of the drive shaft 361. The horizontal sliding block is fixedly connected to the surface of the sealing plate 232. A drive groove 363 is provided on the horizontal sliding block. The drive shaft 361 slides in the drive groove 363. A horizontal sliding rod 233 extends from one side of the hopper 23. The horizontal sliding block 362 is slidably connected to the horizontal sliding rod 233. When the Hall switch 221 starts the drive cylinder 31, the piston rod of the drive cylinder 31 moves downward, causing the sealing plate 232 to move and open the discharge port at the bottom of the hopper. The product inside will be poured into the bag making machine, realizing a linkage effect.
[0028] refer to Figure 1-5 A partition 24 is fixedly connected inside the cavity of the lower feed hopper 23, which is opposite to the bottom surface of the upper feed hopper 22. A telescopic rod 241 is fixedly connected to the partition 24. The telescopic end of the telescopic rod 241 is fixedly connected to the bottom surface of the upper feed hopper 22. A telescopic groove 242 is provided on the telescopic rod 241. A fixing nut 243 that fixes the output end of the telescopic rod 241 is threaded into the telescopic groove 242. The distance between the upper feed hopper 22 and the lower feed hopper 23 can be adjusted to accommodate different feed volumes.
[0029] The working principle of this mechanism is as follows: When feeding materials into the bag-making machine, the plastic granules to be bagged are poured in through the opening of the upper feed hopper 22. The plastic granules accumulate on the closing plate 232 of the lower feed hopper 23, increasing the weight of the closing plate 232 and driving the lower feed hopper 23 to drive the upper feed hopper 22 to descend vertically. When the descending position causes the Hall switch 221 and the magnetic component 12 to come into contact, under the action of electromagnetic induction, the Hall switch 221 will activate the drive cylinder 31. The piston rod of the drive cylinder 31 extends and drives the closing plate 232 to open the opening of the lower feed hopper 23, and the plastic granules accumulated on the closing plate 232 of the lower feed hopper 23 are released. Plastic particles fall into the bag making machine. As the amount of plastic particles inside the feed hopper 23 decreases and the weight decreases, the feed hopper 23 will move upward under the action of the return spring 212, causing the magnetic component 12 and the Hall switch 221 to move away from each other. When they move away to the point that the Hall switch 221 can no longer sense the magnetic component 12, the drive cylinder 31 moves in the opposite direction and drives the sealing plate 232 to close the opening of the feed hopper 23, forming an intermittent feeding effect. During feeding, the height of the telescopic rod 241 can be adjusted according to different feeding requirements, thereby adjusting the distance between the Hall switch 221 and the magnetic component 12 to adapt to different feeding requirements.
[0030] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
