Description

Technical Field

[0001] This utility model relates to the field of composite material production and processing technology, and in particular to an adhesive injection device. Background Technology

[0002] In the production and processing of composite materials, one step is to mix the raw materials (such as the ratio of resin and curing agent) and then inject the mixed materials into the mold to form the final product.

[0003] Currently, common mixing methods include manual mixing and mixing using a pre-made dispensing machine. Manual mixing typically involves using a tank or mixing equipment to mix the hardener and resin in the correct proportions. This process is physically demanding, and the raw materials are easily exposed to the air, resulting in a strong, pungent odor that is detrimental to workers' health. Furthermore, the accuracy of manual mixing is slightly lower, affecting the quality of the final product. On the other hand, existing pre-made dispensing machines are relatively expensive and bulky. They are mostly used at fixed locations, making them inconvenient to move and transport, and lacking flexibility in use.

[0004] Therefore, it is necessary to develop a glue dispensing device to overcome the above-mentioned technical problems. Utility Model Content

[0023] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0024] Example

[0025] like Figure 1 and 2 As shown, the glue dispensing equipment close to production in this embodiment includes a mobile carrier 1 and a glue dispensing tank 2, a curing agent tank 3, and two sets of media pumping components 4 installed on the mobile carrier 1. The media pumping components 4 have media inlets and media outlets. The media inlets of the two sets of media pumping components 4 are respectively connected to the outlets of the glue dispensing tank 2 and the curing agent tank 3. The media outlets of the two sets of media pumping components 4 are respectively connected to glue dispensing pipes 8 through pipelines. The end of the glue dispensing pipe 8 is provided with a glue dispensing connector.

[0026] This embodiment of the glue-dispensing equipment, designed for close proximity to production, employs a skid-mounted design. All components are mounted on a movable carrier 1, allowing for flexible movement to any location requiring operation. During operation, resin and hardener are added to the glue-dispensing tank 2 and the hardener tank 3, respectively. Then, two sets of media pumping components 4 simultaneously pump the materials from the glue-dispensing tank 2 and the hardener tank 3 to the glue-dispensing pipe 8 (this process mixes the two materials in different ratios). The mixture is then injected into the mold through the glue-dispensing connector of the glue-dispensing pipe 8 for molding. During operation, the output flow rates of the glue-dispensing tank 2 and the hardener tank 3 can be flexibly adjusted according to actual needs, thereby achieving real-time adjustment of the material ratio. The entire equipment has a relatively simple structure, low-cost core components, small overall size, light weight, facilitates real-time adjustment of material ratios, has minimal irritating odor, and is relatively safe to operate.

[0027] In this embodiment, the mobile carrier 1 includes a frame and wheels mounted at the bottom of the frame, with a handrail at one end of the frame. The frame is a conventional metal frame, with wheels mounted at different positions on the bottom. The entire device can be moved by pushing it through the handrail, making it quite flexible to use.

[0028] Of course, the walking wheels can also be set to electric walking wheels (such as hub motors), connected to a power supply and controller to achieve automated control of walking.

[0029] In this embodiment, both the top of the dispensing tank 2 and the curing agent tank 3 are provided with openings, and stirring components 5 extending into the openings are respectively provided inside the tanks. The stirring components 5 can be used to thoroughly mix the raw materials in the dispensing tank 2 and the curing agent tank 3, resulting in better raw material quality. Simultaneously, the stirring components 5 can be used to mix and adjust the curing agent and resin raw materials in real time within the dispensing tank 2 and the curing agent tank 3, thereby improving the quality of the final molded product.

[0030] In a preferred embodiment, the stirring assembly 5 includes a motor 51, a mounting cover 52, and a stirring rod 53. The mounting cover 52 is detachably mounted on the opening at the top of the corresponding glue dispensing tank 2 or curing agent tank 3. The motor 51 is mounted on the upper end of the mounting cover 52. The stirring rod 53 is vertically arranged, with its upper end passing through the mounting cover 52 and connected to the shaft of the motor 51. The lower end of the stirring rod 53 is provided with stirring blades.

[0031] In the above implementation scheme, flanges are provided at the top openings of the glue dispensing tank 2 and the curing agent tank 3 respectively. The mounting cover plate 52 is placed on the flange and can be pre-tightened by bolts. When stirring, the motor 51 is energized and turned on, and the stirring rod 53 is driven to rotate, thereby driving the stirring blade to fully stir and mix the material in the tank.

[0032] The motor 51 can be any existing compatible model available on the market. The stirring blades are standard components and will not be described in detail here.

[0033] Of course, the stirring blades can be replaced with multiple horizontally arranged rods that are spaced vertically apart.

[0034] In a preferred embodiment, the aforementioned medium pumping assembly 4 includes a plunger pump 41, an oil pump 42, and an oil tank 43. The suction port of the oil pump 42 is connected to a pipeline extending into the oil tank 43. The plunger pump 41 has an oil chamber and a pump chamber. The oil chamber has an oil inlet and an oil return port. The oil inlet is connected to the discharge port of the oil pump 42 via a first pipeline. The oil return port is connected to the interior of the oil tank 43 via a second pipeline. The pump chamber has a suction port and a discharge port. The suction port is connected to the outlet of the corresponding dispensing tank 2 or curing agent tank 3 via a third pipeline. The discharge port is connected to the dispensing pipe 8 via a pipeline. Buffer tanks 44 are respectively connected to the third pipeline.

[0035] In the above implementation scheme, the oil pump 42 draws the oil from the oil tank 43 through the oil inlet to the oil chamber of the plunger pump 41, and then drives the plunger to move back and forth, thereby generating negative or positive pressure in the pump chamber. Under negative pressure, the raw material in the dispensing tank 2 or the curing agent tank 3 is drawn into the pump chamber. Under positive pressure, the raw material sucked into the pump chamber is pushed out from the outlet (the specific principle of the plunger pump 41 is existing technology and will not be described in detail here), and transported to the downstream dispensing pipe 8, thereby completing the injection of material into the mold. Its structural design is relatively reasonable and the delivery of raw materials is relatively stable.

[0036] It should be noted that in this embodiment, the two sets of media pumping components 4 can share one oil tank 43.

[0037] In a preferred embodiment, the outlets of the pump chambers in the two sets of media pumping components 4 are respectively connected to the confluence chamber 45 via pipelines, and the confluence chamber 45 is connected to the glue injection pipe 8 via pipelines.

[0038] In the above implementation scheme, the design of the merging cavity 45 allows the two raw materials to be premixed (mixed) within the merging cavity 45. Subsequently, after entering the dispensing tube 8, the mixing process continues to complete, and the mixture is finally injected into the mold. The shape of the merging cavity 45 is not particularly limited, as long as it has a certain internal cavity.

[0039] In this embodiment, the merging cavity 45 has an inlet and an outlet. The inlet is connected to a tee, and the remaining two ports of the tee are respectively connected to a third pipeline. The outlet of the merging cavity 45 is connected to a glue injection pipe 8.

[0040] In a preferred embodiment, a cleaning system is also included, which includes a cleaning fluid tank 61 and a cleaning fluid pump 62 connected to the interior of the cleaning fluid tank 61 via a pipeline. The confluence chamber 45 is provided with an inlet connector communicating with its interior. The outlet of the cleaning fluid pump 62 is connected to the inlet connector via a pipeline, and a first control valve is provided on the pipeline.

[0041] In the above implementation scheme, after the glue injection is completed, the glue injection tube 8 is cleaned by the cleaning system. Specifically, the cleaning fluid pump 62 pumps the cleaning medium in the cleaning fluid tank 61 into the confluence chamber 45, and then flows through the confluence chamber 45 to the glue injection tube 8. During the flow, the inside of the glue injection tube 8 is cleaned, which is beneficial for the next glue injection operation. When cleaning is not required, the pipeline can be closed by operating the first control valve.

[0042] In a preferred embodiment, the first pipeline and the second pipeline are respectively equipped with a second control valve, the downstream section of the third pipeline is equipped with a first check valve, and the third pipeline is respectively equipped with a pressure gauge (b in the figure) and a flow control valve (c in the figure).

[0043] In the above implementation scheme, the design of the second control valve allows for the reasonable opening of the hydraulic circuit according to actual operational needs. For example, when injecting oil into the oil chamber, the second control valve on the first pipeline opens, and the second control valve on the second pipeline closes; conversely, during oil return, the second control valve on the first pipeline closes, and the second control valve on the second pipeline opens. Furthermore, the pressure gauge design allows for real-time monitoring of the pipeline pressure, and the flow control valve design allows for adjustment of the medium flow rate within the pipeline, ensuring that the two raw materials are mixed in a suitable ratio and injected into the mold for molding. The design of the first check valve allows the medium pumping assembly 4 to smoothly extract raw materials from the dispensing tank 2 or the curing agent tank 3, while preventing backflow of the raw materials when pushing them into the dispensing pipe 8.

[0044] In a preferred embodiment, the side walls of the glue dispensing tank 2 and the curing agent tank 3 are respectively provided with heating devices 7 for heating the internal medium.

[0045] In the above implementation scheme, the heating device 7 can heat the raw materials in the dispensing tank 2 and the curing agent tank 3, ensuring that the raw materials are maintained at a temperature that is easy to process. For example, the resin in the dispensing tank 2 is maintained at 30℃-50℃, with suitable resin viscosity and good fluidity. Especially when operating in low-temperature environments, the heating device 7 can ensure the smooth operation of the entire equipment.

[0046] In this embodiment, the heating device 7 can be an electric heating blanket wrapped around the glue injection bucket 2 and the curing agent bucket 3. The electric heating blanket is made of a fabric material that is easy to conduct heat and has heating resistance wires inside.

[0047] As a preferred embodiment, the side walls of the above-mentioned glue dispensing tank 2 and curing agent tank 3 are provided with level gauges (d in the figure).

[0048] In the above implementation scheme, the level gauge can reflect the liquid level of the medium in the dispensing tank 2 and the curing agent tank 3 in real time, and replenish it in time when the liquid level is low.

[0049] In this embodiment, the top of the glue dispensing tank 2 and the curing agent tank 3 are provided with dispensing ports that can be opened or closed.

[0050] In this embodiment, a power supply and a controller (which can be a PLC controller, an industrial computer, or other existing types of controllers) can be configured on the mobile carrier 1. The controller connects the power supply and the electrical components in the equipment to achieve automated control.
