Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to a bottom-feed packaging device. Background Technology

[0002] Repackaging is the process of quantitatively dispensing pre-prepared or manufactured rubber compound into specific containers. Repackaging is a necessary process for making samples or products, and therefore, the quality of repackaging determines the quality of the product. If air is mixed into the specific container, it will affect the product quality.

[0003] Currently, whether it's laboratory sample packaging or mass production packaging, there are two main packaging methods: ① Direct pouring method, which involves pouring the adhesive directly from the top port of the bottle. This method is simple, convenient, and quick, but the disadvantage is that it's most prone to mixing in air and impurities, especially for high-viscosity adhesives, which are difficult to pour in; ② Mechanical top-feeding method, which involves extending the equipment's discharge pipe into the bottom of the tube and using machinery to press out the adhesive, filling the tube from bottom to top. The advantages are less air mixing, accurate metering, and a more mature process, making it a commonly used method in production. The disadvantages are high equipment costs, the inability to completely prevent air mixing, and the tendency to contaminate the tube.

[0004] In view of this, there is an urgent need for a bottom-feeding dispensing device to solve the above problems. Summary of the Invention

[0005] To help solve the problems existing in the prior art, this utility model provides a bottom-feed dispensing device, which adopts the following technical solution: it includes a container, a pressure plate, a glue bottle and a driving mechanism. The container opening is set upward. The outer diameter of the pressure plate is adapted to the inner diameter of the container. One end of the glue bottle is provided with a glue inlet and the other end is provided with a through hole. The glue inlet and the through hole of the glue bottle are respectively provided with a front cover and a rear cover. The pressure plate is provided with a dispensing hole for connecting with the glue inlet of the glue bottle.

[0006] The drive mechanism is used to drive the pressure plate to move up and down inside the container.

[0007] Its further feature is that,

[0008] The drive mechanism includes a cylinder and a pneumatic valve switch, the pneumatic valve switch being used to control the cylinder push rod to rise or fall.

[0009] The pressure plate has a plurality of first support rods on its top surface, and a top plate is provided on the top surface of the plurality of first support rods. The push rod of the cylinder is connected to the top of the top plate.

[0010] The pressure plate is equipped with an exhaust ball valve.

[0011] The dispensing hole is provided with a connector with external threads, and the glue inlet of the glue bottle has an internal thread that matches the connector.

[0012] It also includes a chassis, several second support rods disposed on the top surface of the chassis, and a mounting plate disposed on the top of the second support rods. The container is disposed above the chassis, and the cylinder is disposed on the mounting plate.

[0013] The top surface of the chassis is provided with a positioning groove.

[0014] The dispensing hole is located at the center of the pressure plate.

[0015] The glue bottle is threadedly connected to the front cover.

[0016] The above-described structure of this utility model can achieve the following beneficial effects:

[0017] When using, pour the adhesive into the container quickly to avoid air contamination. Then, press the pressure plate into the container. Next, connect the glue bottle inlet to the dispensing hole of the pressure plate. The drive mechanism drives the pressure plate to move downwards inside the container. As the pressure plate presses down, it forces the adhesive into the glue bottle through the dispensing hole. Once the adhesive reaches a specific position on the glue bottle, stop pressing. Insert the back cap of the glue bottle, then remove the glue bottle from the pressure plate and replace the front cap to complete the dispensing process. Attached Figure Description

[0020] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0021] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0022] The following is in conjunction with the appendix Figure 1 The present invention will be described in further detail below.

[0023] Reference Figure 1 A bottom-feed dispensing device includes: a container 1 (the container 1 is a sufficiently thick stainless steel high-pressure container), a pressure plate 2, a glue bottle 3, and a driving mechanism. The container 1 has its opening facing upwards. The outer diameter of the pressure plate 2 is adapted to the inner diameter of the container 1. One end of the glue bottle 3 is provided with a glue inlet, and the other end is provided with a through hole. The glue inlet and the through hole of the glue bottle 3 are respectively provided with a front cover and a rear cover (the glue bottle 3 and the front cover are preferably threaded to facilitate quick closing and opening of the glue inlet). The pressure plate 2 is provided with a dispensing hole for connecting to the glue inlet of the glue bottle 3 (preferably...). (Set at the center of pressure plate 2); Thus, when using, pour the adhesive into container 1 quickly to avoid air mixing in, then press pressure plate 2 into container 1, and then connect the inlet of adhesive bottle 3 to the dispensing hole of pressure plate 2 (remove the front and back covers of adhesive bottle 3 beforehand). The drive mechanism drives pressure plate 2 to move downward in container 1. Pressure plate 2 presses down, pushing the adhesive into adhesive bottle 3 from the dispensing hole. After the adhesive reaches a specific position in adhesive bottle 3, the pressing stops. Insert the back cover of adhesive bottle 3, then remove adhesive bottle 3 from pressure plate 2, and put on the front cover to complete the dispensing.

[0024] like Figure 1 As shown, the driving mechanism specifically includes a cylinder 4 and a pneumatic valve switch. The pneumatic valve switch is used to control the push rod of the cylinder 4 to rise or fall, so as to drive the pressure plate 2 to rise or fall. In order to avoid interference with the glue bottle 3 when the cylinder 4 drives the pressure plate 2, a number of first support rods 5 are provided on the top surface of the pressure plate 2, and a top plate 6 is provided on the top surface of the number of first support rods 5. The push rod of the cylinder 4 is connected to the top of the top plate 6. The space between the pressure plate 2, the top plate 6 and the number of first support rods 5 is the installation space for the glue bottle 3.

[0025] Further optimizations include, for example Figure 1 As shown, the pressure plate 2 is equipped with an exhaust ball valve 7. When the pressure plate 2 is pressed into the container 1, the exhaust ball valve 7 is opened. When the pressure plate 2 is pressed onto the surface of the rubber material, the air in the container 1 is discharged through the exhaust ball valve 7 to prevent air from entering the rubber bottle 3.

[0026] Further optimization involves facilitating the assembly and disassembly of the glue bottle 3 and the pressure plate 2. A connector with external threads is provided at the dispensing hole, and the glue inlet of the glue bottle 3 has an internal thread that matches the connector. By screwing the glue bottle 3, the glue inlet of the glue bottle can be connected or separated from the connector.

[0027] like Figure 1As shown, this application also includes a chassis 8, a plurality of second support rods 9 disposed on the top surface of the chassis 8, and a mounting plate 10 disposed on the top of the second support rods 9. The container 1 is disposed above the chassis 8, and the cylinder 4 is disposed on the mounting plate 10. Thus, the chassis 8, the mounting plate 10, and the plurality of second support rods 9 form a dispensing space. During dispensing, the container 1, the pressure plate 2, and the glue bottle 3 are placed in the dispensing space for dispensing.

[0028] A further optimization is that, in order to facilitate the placement of container 1 into the designated position on chassis 8 for easy dispensing, a positioning groove 11 is provided on the top surface of chassis 8, which is adapted to the bottom of container 1.

[0029] A further optimization is that a sealing ring is provided on the circumferential side of the pressure plate 2.

[0030] In summary, after the experimental adhesive is prepared, pour the adhesive into container 1 quickly to avoid air contamination. Then, press the pressure plate 2 into container 1 and open the exhaust ball valve 7 to expel air when the pressure plate 2 presses against the adhesive surface. Then, close the exhaust ball valve 7. Next, screw the adhesive bottle 3 into the pressure plate 2. Finally, place container 1 with the pressure plate 2 in the dispensing space and start pressing down the cylinder 4 by switching the pneumatic valve. The pressure plate 2 presses down, drawing the adhesive from the dispensing port into the adhesive bottle 3. Once the adhesive bottle reaches a specific position, switch the pneumatic valve to stop the cylinder 4 from pressing. Insert the back cap of the adhesive bottle 3, unscrew the bottle 3 to separate it from the pressure plate 2, and then replace the front cap to complete the dispensing process.

[0031] This application allows for a simple and convenient way to dispense adhesive into glue bottles 3, especially for high-viscosity, non-flowing adhesives. During dispensing, air bubbles in container 1 are eliminated, preventing air bubbles from entering glue bottles 3, and quantitative dispensing into glue bottles 4 can be easily achieved.

[0032] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
