Description

Technical Field

[0001] This utility model relates to the field of resin filling technology, and more specifically, to a quantitative filling device for water-based resin. Background Technology

[0002] A resin metering filling device refers to a specialized piece of equipment used for the precise dispensing and filling of water-based resin materials (such as epoxy resin, polyurethane, silicone, etc.). It is widely used in electronic packaging, composite material manufacturing, adhesive production, and handicrafts. Its core function is to quantitatively fill liquid or semi-solid resin into filling barrels or other containers as needed.

[0003] Chinese Patent Announcement No. CN215402998U provides a large-volume resin filling assembly. This design features a lower cylinder portion positioned at the bottom of an upper cylinder portion. The upper cylinder portion has a feed inlet on its surface, while the lower cylinder portion has a water inlet on its surface. The assembly has a large volume, which improves the efficiency of a single filling operation. At the same time, the reasonable distribution of the inlets and outlets further ensures the filling efficiency of the product, prevents unnecessary waste, and reduces production costs.

[0004] Because of the high viscosity of resin, manufacturers use submersible filling to reduce the generation of gas inside the resin during filling. However, the current submersible filling process requires inserting the delivery tube into the bottom of the container. When the container is full and the delivery tube is removed, a large amount of viscous resin will adhere to the outer surface of the delivery tube. When switching containers, the resin will easily drip down, which not only results in waste but also contaminates the production line.

[0005] Therefore, a water-based resin quantitative container is proposed to address the above problems. Utility Model Content

[0006] 1. Technical problems to be solved

[0007] This invention provides a water-based resin quantitative filling device, which can improve the problems existing in related technologies: when the barrel is filled and the conveying pipe is taken out, a large amount of viscous resin will adhere to the outer surface of the conveying pipe. When switching barrels, the resin will easily drip down, which not only causes waste but also contaminates the production line.

[0008] 2. Technical Solution

[0009] To solve the above problems, the present invention adopts the following technical solution.

[0010] This application provides a water-based resin quantitative filling device, including a silo, a fixed support, a control center, and a mounting frame. The silo is used to store resin and is fixedly installed on the fixed support. The control center is used to control the discharge of resin from the silo. A base plate is fixedly connected to the bottom end of the mounting frame, and a telescopic cylinder is fixedly installed on the outer end of the mounting frame.

[0012] (1) Multiple scraper plates are rotatably installed at the bottom of the movable plate. The multiple scraper plates abut against each other to form a circle and wrap around the conveying pipe. When the conveying pipe is taken out of the bucket, the force of the telescopic spring will push the movable plate against the bucket opening. At this time, when the conveying pipe moves upward, the scraper plates surrounding the outer surface of the conveying pipe will scrape the outer surface of the conveying pipe, so that the resin adhering to the surface can be scraped off and enter the bucket, thereby preventing the resin from dripping down when changing buckets, which can prevent waste and pollution of the production line.

[0013] (2) When the conveying pipe is inserted into the barrel, its movable plate abuts against the barrel opening, the fixed plate moves downward to compress the telescopic spring, and the sleeve abuts against the outer ring of the barrel opening through the abutting ring. Thus, the sleeve can exert downward pressure on the barrel through the force of the telescopic spring, so that the barrel can be placed more stably on the bottom plate and prevent it from tipping over during filling.

[0014] In some embodiments, the bottom of the hopper is fixedly connected to an output pipe that communicates with the interior, and the end of the output pipe away from the hopper is mounted on the outer end of the mounting frame via a bracket.

[0015] In some embodiments, an input pipe is fixedly connected to the outer end of the output connector, and a connecting hose is fixedly installed between the input pipe and the output pipe. The material conveying pipe is connected to the hopper in sequence through the output connector, the input pipe, the connecting hose, and the output pipe.

[0016] In some embodiments, the pressure assembly includes a fixed plate and a movable plate. The fixed plate is fixedly installed on the outer end of the output connector, and a pair of slide rods are fixedly installed on the top of the movable plate. The end of the slide rod away from the movable plate passes through the fixed plate, and the slide rod is slidably connected to the fixed plate.

[0017] In some embodiments, the movable plate has a through hole at its outer end, one end of the conveying pipe extends downward through the fixed plate and the through hole, and the slide rod is fitted with a telescopic spring at its outer end, with both ends of the telescopic spring abutting against the fixed plate and the movable plate respectively.

An abutment ring is fixedly connected to the bottom end of the sleeve, and an adhesive strip is installed at the bottom of the abutment ring.

[0019] In some embodiments, the scraping assembly further includes a plurality of mounting blocks, and the scraper has two mounting notches at its outer end. The plurality of mounting blocks are fixedly mounted on the bottom of the movable plate. The scraper is rotatably mounted on the bottom of the movable plate through the mounting notches and the mounting blocks. A baffle is fixedly mounted on the bottom of the scraper.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0041] Please see Figures 1-6 A water-based resin quantitative storage device includes a silo 1, a fixed support 2, a control center 3, and a mounting frame 8. The silo 1 is used to store resin and is fixedly mounted on the fixed support 2. The control center 3 is used to control the discharge of resin from the silo 1. A base plate 10 is fixedly connected to the bottom end of the mounting frame 8. A telescopic cylinder 11 is fixedly mounted on the outer end of the mounting frame 8. An output connector 6 is fixedly connected to the output end of the telescopic cylinder 11. A conveying pipe 9 for discharging resin is fixedly connected to the bottom end of the output connector 6. A pressing component 7 is provided at the bottom end of the pressing component 7. A scraping component 12 is provided at the bottom end of the pressing component 7. The scraping component 12 includes multiple petal-shaped scraping blades 125. The multiple scraping blades 125 are arranged in a ring, and the two sides of the multiple scraping blades 125 abut against each other. The bottom of the multiple scraping blades 125 abuts against the outer surface of the conveying pipe 9.

[0042] The bottom of the hopper 1 is fixedly connected to an output pipe 4 that communicates with the interior. The end of the output pipe 4 away from the hopper 1 is installed on the outer end of the mounting frame 8 via a bracket.

[0043] An input pipe 5 is fixedly connected to the outer end of the output connector 6. A connecting hose 13 is fixedly installed between the input pipe 5 and the output pipe 4. The material conveying pipe 9 is connected to the hopper 1 through the output connector 6, the input pipe 5, the connecting hose 13 and the output pipe 4 in sequence.

[0044] The device in this solution is mainly used for quantitative filling of water-based resin into packaging barrels. Due to the high viscosity of the resin, a submersible filling process is adopted, that is, the delivery pipe 9 is inserted into the bottom of the barrel to prevent the resin from fluctuating during filling and to prevent the formation of air bubbles inside. However, the resin will also adhere to the delivery pipe 9, which can be improved in this solution. The hopper 1 is installed on the fixed support 2. The interior of the hopper 1 is hollow and stores the resin for filling. A pressure pump is built into the bottom outlet of the hopper 1. It is not only used for pressurization, but also works with the control center 3 to realize quantitative filling. The control center 3 is mainly used for system logic control. It receives sensor signals such as flow rate, temperature, and pressure, executes preset logic programs, and controls the start, stop, and speed of the metering pump, valves, and mixer, thereby realizing automatic quantitative filling.

[0045] A base plate 10 is fixed at the bottom of the mounting frame 8. In addition to placing the filling barrel, the base plate 10 also houses a weighing scale, which works in conjunction with the control center 3 to more accurately control the filling volume. A telescopic cylinder 11 is installed at the outer end of the mounting frame 8. An output connector 6 is fixed on the telescopic piston rod of the telescopic cylinder 11, and a conveying pipe 9 is fixed at the bottom of the output connector 6. This pipe is mainly used to insert into the filling barrel to output resin. The telescopic cylinder 11 requires an external air supply device, which works in conjunction with the control center 3 to control the raising and lowering of the output connector 6 and the conveying pipe 9. The telescopic cylinder 11 is mainly composed of a cylinder barrel, piston, piston rod, and seals. With the cooperation of the air supply device and the control center 3, it can achieve linear motion with high repeatability.

[0046] An output pipe 4 is installed at the bottom of the silo 1. The output pipe 4 is mainly used to output the resin in the silo 1. Valves, temperature sensors and pressure sensors are installed at the outer end of the output pipe 4. The end of the output pipe 4 away from the silo 1 is mounted on the mounting frame 8 by a bracket. The outer end of the output connector 6 is connected to the input pipe 5. Both the input pipe 5 and the output pipe 4 are made of hard metal or plastic. The output pipe 4 and the input pipe 5 are connected by a connecting hose 13. The connecting hose 13 is made of deformable rubber, so that the connection can be kept stable when the telescopic cylinder 11 drives the output connector 6 and the conveying pipe 9 to move up and down. At the same time, through the cooperation of the output pipe 4, the connecting hose 13, the input pipe 5 and the output connector 6, the resin in the silo 1 can be filled into the barrel through the conveying pipe 9.

[0047] A pressing component 7 is installed at the bottom of the output connector 6, and a scraping component 12 is installed at the bottom of the pressing component 7. Multiple scraping plates 125 are rotatably installed at the bottom of the movable plate 74. The multiple scraping plates 125 abut against each other to form a circle and wrap around the conveying pipe 9. When the conveying pipe 9 is taken out of the barrel, the force of the telescopic spring 72 will push the movable plate 74 against the barrel opening. At this time, when the conveying pipe 9 moves upward, the scraping plates 125 surrounding the outer surface of the conveying pipe 9 will scrape the outer surface of the conveying pipe 9, so that the resin adhering to the surface can be scraped off and put into the barrel, thereby preventing the resin from dripping when changing barrels, preventing waste and contamination of the production line.

[0048] Please see Figure 3 The pressing component 7 includes a fixed plate 71 and a movable plate 74. The fixed plate 71 is fixedly installed on the outer end of the output connector 6. A pair of slide rods 73 are fixedly installed on the top of the movable plate 74. The end of the slide rod 73 away from the movable plate 74 passes through the fixed plate 71 and is slidably connected to the fixed plate 71.

[0049] The movable plate 74 has a through hole 75 at its outer end. One end of the conveying pipe 9 passes through the fixed plate 71 and the through hole 75 and extends downward. The slide rod 73 is fitted with a telescopic spring 72 at its outer end. The two ends of the telescopic spring 72 abut against the fixed plate 71 and the movable plate 74, respectively.

[0050] In this design, the pressing component 7 can not only press the scraping component 12 downwards so that it can scrape off the resin adhering to the surface of the conveying pipe 9, but also press the mouth of the barrel to improve the stability of the barrel during filling. The fixed plate 71 is fixed to the bottom of the output connector 6, and two symmetrical sliding rods 73 are fixed on the movable plate 74. The fixed plate 71 and the movable plate 74 are coaxially arranged, and both sliding rods 73 pass through the fixed plate 71 and are slidably connected to it. A through hole 75 is opened at the outer end of the movable plate 74, which is mainly used to allow the conveying pipe 9 to pass through. The conveying pipe 9 passes through both the fixed plate 71 and the through hole 75 and extends into the scraping component 12 below. A telescopic spring 72 is sleeved on the outer end of the sliding rod 73. The two ends of the telescopic spring 72 abut between the fixed plate 71 and the movable plate 74, and the movable plate 74 is pushed downward by the force of the telescopic spring 72.

[0051] When the feed pipe 9 is inserted into the filling barrel, the movable plate 74 will press the scraper assembly 12 against the barrel opening, while the fixed plate 71 will move downward with the output connector 6, compressing the telescopic spring 72, so that the telescopic spring 72 can press the scraper assembly 12 tightly against the barrel through the force.

[0052] Please see Figures 4-6The scraper assembly 12 also includes a sleeve 121, which is fixedly installed at the bottom of the movable plate 74. Multiple annularly distributed spring pieces 124 are fixedly installed on the inner side wall of the sleeve 121. The outer ends of the spring pieces 124 abut against the scraper plate 125. An abutment ring 122 is fixedly connected to the bottom end of the sleeve 121, and a rubber strip 123 is installed at the bottom of the abutment ring 122.

[0053] The scraper assembly 12 also includes multiple mounting blocks 126. The scraper plate 125 has two mounting notches 128 at its outer end. The multiple mounting blocks 126 are fixedly installed at the bottom of the movable plate 74. The scraper plate 125 is rotated and installed at the bottom of the movable plate 74 through the mounting notches 128 and mounting blocks 126. A baffle 127 is fixedly installed at the bottom of the scraper plate 125.

[0054] In this design, the sleeve 121 is fixed to the bottom of the movable plate 74, and the conveying pipe 9 extends into the inside of the sleeve 121. At the bottom of the movable plate 74, multiple mounting blocks 126 are fixed in a ring and are evenly distributed. The scraper 125 has mounting notches 128 on the top of both sides. The mounting notches 128 match the mounting blocks 126. The scraper 125 is rotatably connected to the mounting blocks 126 through the mounting notches 128, and is thus rotatably mounted on the bottom of the movable plate 74. Multiple scraper 125 are arranged together to form a circle. Since the scraper 125 is petal-shaped, it will form a semi-spherical shape when they are arranged together. The conveying pipe 9 passes through the middle. The bottom of the scraper 125 abuts against the outer surface of the conveying pipe 9 to scrape the surface of the conveying pipe 9. A baffle 127 is fixed at the bottom of the scraper 125. The baffle 127 is inclined relative to the scraper 125.

[0055] At the bottom of the sleeve 121, an abutment ring 122 is fixed, and at the bottom of the abutment ring 122, a rubber strip 123 is fixed to increase friction. On the inner side of the sleeve 121, multiple spring pieces 124 corresponding one-to-one with the number of scraper plates 125 are fixed. The spring pieces 124 are inclined and their bottoms abut against the outer surface of the scraper plate 125. The spring pieces 124 are made of elastic plastic. The force of the spring pieces 124 can push the scraper plate 125 inward so that the scraper plate 125 can always abut against the surface of the conveying pipe 9.

[0056] When the conveying pipe 9 moves downward and inserts into the barrel under the action of the telescopic cylinder 11, the barrel opening will be located between the baffle 127 and the sleeve 121. Its movable plate 74 abuts against the barrel opening, and the fixed plate 71 moves downward to compress the telescopic spring 72. The sleeve 121 abuts against the outer ring of the barrel opening through the abutment ring 122 and the rubber strip 123. Thus, the force of the telescopic spring 72 can make the sleeve 121 exert downward pressure on the barrel, so that the barrel can be placed more stably on the bottom plate 10 and prevent it from tipping over during filling.

[0057] When the feed pipe 9 moves upward, the force of the telescopic spring 72 keeps the movable plate 74 pressed against the barrel opening. At this time, the slide bar 73 will also slide and reset on the fixed plate 71. Simultaneously, the scraper 125 will scrape the surface of the feed pipe 9, scraping off the resin adhering to the surface of the feed pipe 9 and letting it fall into the barrel. The baffle 127 fixed at the bottom of the scraper 125 serves to prevent the resin from spreading to the outer surface of the scraper 125, causing it to fall into the barrel under the obstruction of the baffle 127. Through the cooperation of the scraper 125 and the baffle 127, the resin adhering to the surface of the feed pipe 9 can be scraped off, reducing waste during filling and preventing dripping resin from contaminating the production line.

[0058] Working principle: When using this device for filling, the conveying pipe 9 is first inserted into the barrel by the drive of the telescopic cylinder 11. At this time, the movable plate 74 is pressed against the barrel opening. The sleeve 121 can exert downward pressure on the barrel by the force of the telescopic spring 72 to prevent the barrel from tipping over during filling. Then, the resin is poured into the barrel by the cooperation of the control center 3 and the hopper 1.

[0059] When the conveying pipe 9 moves upward, the force of the telescopic spring 72 keeps the movable plate 74 pressed against the barrel opening. At the same time, the scraper plate 125 scrapes the surface of the conveying pipe 9, scraping off the resin adhering to the surface of the conveying pipe 9 and letting it fall into the barrel, reducing waste during filling and preventing dripping resin from contaminating the production line.
