Description

Technical Field

[0001] This utility model relates to the field of sealant processing technology, specifically to a base material metering device for processing silicone sealant finished products. Background Technology

[0002] Silicone sealant is a paste-like substance made primarily of polydimethylsiloxane, supplemented with crosslinking agents, fillers, plasticizers, coupling agents, and catalysts, mixed under vacuum. It cures at room temperature by reacting with moisture in the air to form an elastic silicone rubber. It exhibits strong adhesion, high tensile strength, and also possesses weather resistance, vibration resistance, moisture resistance, odor resistance, and adaptability to large temperature variations, enabling bonding between most building materials. Silicone sealant requires a disperser for mixing during processing.

[0003] Utility model CN212283987U discloses a dynamic mixing reaction device for silicone sealant, including a frame, a stirring mechanism, a reaction tank, a vacuum device, and a metering device. The stirring mechanism is installed on the upper part of the frame, the reaction tank is installed on the bottom of the frame, and the tank cover is located in the lower middle part of the stirring mechanism and connected to the reaction tank. The vacuum device and the metering device are respectively installed on the upper two sides of the frame. The vacuum device is connected to the tank cover through a connecting air pipe, and the metering device is connected to the tank cover through a conveying pipe. The advantages of this utility model are: the stirring mechanism, reaction tank, vacuum device, and metering device allow the stirring mechanism to stir the sealant material in the reaction tank, the vacuum device to remove air from the reaction tank, thus preventing air from affecting the reaction quality, and the metering device to facilitate quantitative conveying, resulting in a proper reaction material ratio and improved sealant quality.

[0004] However, the aforementioned existing technology still has shortcomings in use: its metering device can only inject one type of base material (such as vulcanized silicone rubber, methyl MQ silicone resin, petroleum resin, etc.) into the reaction tank at a time, which results in low base material addition efficiency, thus affecting the overall processing efficiency of the finished product.

[0005] Therefore, this utility model provides a base material metering device for processing silicone sealant finished products. Utility Model Content

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide a base material metering device for processing silicone sealant finished products, thereby solving the problems mentioned in the background art. This invention has the function of adding two base materials simultaneously in a single operation, which greatly improves the efficiency of base material addition.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: a metering device for base material in the processing of silicone sealant finished products, comprising a support frame and a piston-type metering cylinder. The piston-type metering cylinder is provided with an outlet pipe and an inlet pipe on its body. Two adjacent piston-type metering cylinders are arranged in the support frame. A metering limiting structure is provided on one side of the piston-type metering cylinder on the support frame. This limiting structure has the function of adjusting the stroke limit of the stopper rod on the adjacent piston-type metering cylinder. A lifting rod is provided at the top of the support frame. The moving end of the lifting rod is connected to a differential assembly. Arms are provided on both sides of the differential assembly and are respectively fixedly connected to the top of the stopper rod on the two adjacent piston-type metering cylinders.

[0008] Furthermore, the support frame is a rectangular frame structure, the cylinder is set through the bottom of the support frame from top to bottom, and the liquid outlet pipe and liquid inlet pipe are both located below the support frame.

[0009] Furthermore, the limiting structure includes a grooved frame, a lead screw, and a threaded sleeve. The grooved frame is fixedly installed on one side of the support frame. The two ends of the lead screw are fixedly connected to the upper and lower sides of the grooved frame. The threaded sleeve is screwed onto the lead screw. A cantilever is fixedly connected to the outer wall of the stopper rod. One end of the cantilever is fixedly connected to a limiting sleeve that is sleeved on the lead screw and located below the threaded sleeve.

[0010] Furthermore, a scale plate located on one side of the lead screw is fixedly connected to one side of the slotted frame.

[0011] Furthermore, the differential assembly includes a suspension frame and sliding plates located on both sides of the suspension frame. The top of the suspension frame is fixedly connected to the actuating end of the lifting rod, and its two sides slide vertically with the sliding plates. A transmission gear that meshes with one side of the sliding plate is provided in the middle of the suspension frame, and one end of the boom is fixedly connected to one side of the sliding plate.

[0012] Furthermore, a C-shaped notch is provided on one side of the crossbeam at the bottom of the support frame for fixed connection with the cylinder.

[0013] Furthermore, the bottom of the crossbeam is fixedly connected to support legs near both ends.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, a support frame is provided, and two piston-type metering cylinders are set inside the support frame. A lifting rod for controlling the injection of materials into the two piston-type metering cylinders is set at the top of the support frame, so that the metering device can add two base materials at the same time, which greatly improves the efficiency of base material addition.

[0016] 2. In this utility model, a limiting structure is set in the support frame. The function of the limiting structure is to control the amount of base material added by the piston metering cylinder. A differential combination is set between the lifting rod and the two piston metering cylinders, so that the two piston metering cylinders can add two different base materials in a variable manner, which has the advantage of adding various base materials in proportion at the same time.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Please see Figures 1 to 3 This utility model provides a technical solution: a metering device for base material in the processing of silicone sealant finished products, including a support frame 1 and a piston-type metering cylinder 2. The cylinder body 24 of the piston-type metering cylinder 2 is equipped with an outlet pipe 21 and an inlet pipe 22. The outlet pipe 21 is located at the bottom of the cylinder body 24. One-way valves are connected in series to both the outlet pipe 21 and the inlet pipe 22. A piston is installed inside the cylinder body 24, and a stopper rod 23 is fixedly connected to one side of the piston. When the piston moves up and down, liquid enters through the inlet pipe 22 and exits through the outlet pipe 21. The cylinder body 24 is equipped with graduations. The support frame 1 has a rectangular frame structure, and the cylinder body 24 extends vertically through the bottom of the support frame 1. Both the outlet pipe 21 and the inlet pipe 22 are located below the support frame 1.

[0023] In this technical solution, two adjacent piston-type metering cylinders 2 are arranged in the support frame 1. The piston-type metering cylinders 2 are vertically arranged. A metering limiting structure 3 is arranged on one side of the piston-type metering cylinders 2 on the support frame 1. The limiting structure 3 has the function of limiting and adjusting the stroke of the stopper rod 23 on the adjacent piston-type metering cylinders 2. That is, by controlling the stroke of the stopper rod 23 extending outward, the dosage of liquid entering the cylinder 24 through the liquid inlet pipe 22 can be adjusted, thereby realizing the function of quantitative liquid aspiration.

[0024] Specifically, the limiting structure 3 includes a channel frame 31, a lead screw 32, and a threaded sleeve 33. The channel frame 31 is fixedly installed on one side inside the support frame 1. The two ends of the lead screw 32 are fixedly connected to the upper and lower sides inside the channel frame 31. The threaded sleeve 33 is screwed onto the lead screw 32. A cantilever 231 is fixedly connected to the outer wall of the stopper rod 23. One end of the cantilever 231 is fixedly connected to a limiting sleeve 2311 that is sleeved on the lead screw 32 and located below the threaded sleeve 33. The limiting sleeve 2311 and the lead screw 32 are in clearance fit. When the threaded sleeve 33 rotates, it will move up and down, thereby limiting the height of the limiting sleeve 2311. A scale plate 311 located on one side of the lead screw 32 is fixedly connected to one side inside the channel frame 31. The scale plate 311 is consistent with the scale on the cylinder 24. The position where the threaded sleeve 33 needs to stop can be determined by the scale plate 311.

[0025] A lifting rod 4 is provided on the top of the support frame 1. The lifting rod 4 is a cylinder structure. The actuating end of the lifting rod 4 is connected to a differential assembly 6. When the lifting rod 4 is actuated, it can control the overall up and down movement of the differential assembly 6. The differential assembly 6 is provided on both sides with arms 61 that are fixedly connected to the top of the stopper rods 23 on two adjacent piston-type measuring cylinders 2. The differential assembly 6 can ensure that the stopper rods 23 on the two piston-type measuring cylinders 2 can move up to the position defined by the corresponding threaded sleeve 33.

[0026] Specifically, the differential assembly 6 includes a hanging frame 62 and sliding plates 63 located on both sides of the hanging frame 62. The top of the hanging frame 62 is fixedly connected to the actuating end of the lifting rod 4, and its two sides slide up and down with the sliding plates 63. A transmission gear 64 is provided in the middle of the hanging frame 62, which meshes with one side of the sliding plate 63. In this embodiment, there are two sliding plates 63, and teeth that mesh with the transmission gear 64 are provided on opposite sides of the two sliding plates 63. That is to say, the sliding directions of the two sliding plates 63 are opposite. One end of the arm 61 is fixedly connected to one side of the sliding plate 63, and one sliding plate 63 corresponds to one arm 61.

[0027] In this embodiment, a C-shaped notch 111 is provided on one side of the crossbeam 11 at the bottom of the support frame 1, which is fixedly connected to the cylinder 24. The C-shaped notch 111 is provided to prevent the crossbeam 11 from obscuring the scale on the cylinder 24.

[0028] In this embodiment, the bottom of the crossbeam 11 is fixedly connected to the support legs 112 near both ends. The bottom of the support legs 112 is welded with a mounting base, which allows the device to be installed in the desired position.

[0029] Working principle: Before use, install multiple units of this device as needed according to the type of base material to be added. During use, connect the inlet pipe 22 of the two piston metering cylinders 2 to the corresponding base material cylinders through hoses, and then connect the outlet pipe 21 to the reaction tank through a pipeline. When base material needs to be added, manually rotate the threaded sleeve 33 to determine the height of the stopper rod 23 according to the required base material dosage ratio. Then control the lifting rod 4 to drive the lifting frame 62 to rise. At this time, the two stopper rods 23 will passively and adaptively rise, and the corresponding cylinder 24 will suck up the material through the inlet pipe 22. When the limiting sleeve 2311 corresponding to one of the stopper rods 23 presses against the corresponding threaded sleeve 33, the slide plate 63 corresponding to that stopper rod 23 will stop moving upward, and the cylinder 24 will finish sucking up the liquid. As the lifting frame 62 continues to rise, the other slide plate 63 will accelerate upward under the action of the transmission gear 64 until the corresponding cylinder 24 finishes sucking up the liquid. At this time, the two cylinders 24 have completed quantitative liquid sucking. Then control the lifting rod 4 to drive the differential combination 6 to descend as a whole. At this time, the different base materials in the two cylinders 24 are injected into the reaction tank.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
