[0002] When producing and preparing adhesives, a professional reaction kettle is usually used. Materials and solvents are added into the reaction kettle, and adhesives are generated through stirring, mixing and mutual reaction. Then, a feeding pipe is arranged at the bottom of the reaction kettle for discharging the produced adhesives.

[0003] However, due to the physical properties of adhesives, they have a high viscosity. After flowing out from the discharging pipe during discharging, when the discharging valve is closed, there will still be some remaining materials slowly dripping out of the discharging nozzle, polluting the external environment. Therefore, the discharging nozzle is usually set to be rotatable. First, the valve is closed, and then the discharging nozzle is turned upwards so that the remaining materials inside the discharging nozzle flow back and are stored inside the discharging nozzle. However, this process is troublesome to operate, and the turned-up discharging nozzle also needs to be fixed additionally to prevent it from naturally turning downwards due to gravity. Therefore, a discharging device for adhesive preparation is provided specifically to solve the above problems. Content of the Utility Model

[0019] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model are described clearly and completely. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0020] By providing a discharging device for adhesive preparation in the embodiments of the present application, the problem that in the existing discharging structure during the adhesive preparation process, after discharging, it is necessary to first close the valve, and then turn the discharging nozzle upward so that the remaining material inside the discharging nozzle flows back and is stored inside the discharging nozzle, and the turned discharging nozzle also needs to be fixed additionally, which is troublesome to operate, is solved.

[0021] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific implementation modes.

[0022] The embodiments of the present utility model disclose a discharging device for adhesive preparation.

[0023] According to the attached Figures 1 - 3 As shown, it includes a glue outlet pipe 1. Glue outlet nozzles 2 are rotatably arranged on both sides of the front end of the glue outlet pipe 1. A sealing and driving integrated part 3 is arranged between the glue outlet pipe 1 and the glue outlet nozzles 2. The sealing and driving integrated part 3 includes a pull rod 31, a piston head 310, a rack 38 and a gear 39;

[0024] The pull rod 31 is movably inserted into the glue outlet pipe 1. The piston head 310 is fixedly installed at the end of the pull rod 31. The gear 39 is fixedly installed on the outer wall of the glue outlet nozzle 2. The racks 38 are fixedly arranged on both sides of the pull rod 31. The racks 38 and the gear 39 are meshed with each other. An inner conical seal 12 is fixedly arranged inside the glue outlet pipe 1. The pull rod 31 penetrates through the inner conical seal 12, and the piston head 310 is movably inserted into the inner conical seal 12.

[0025] After blanking is completed, by pulling the extraction rod 31 outwards, the extraction rod 31 drives the piston head 310 to move into the inner conical seal 12. When the end of the piston head 310 just enters the inner conical seal 12, the material stop is completed. At the same time, the rack 38 contacts the gear 39, and then continue to pull, so that the rack 38 drives the gear 39 to rotate, so that the two groups of glue nozzles 2 are turned upwards, synchronously realizing the material stop and the turning action of the glue nozzles 2. The operation is convenient, and the material inside the glue outlet pipe 1 presses against the piston head 310, so that the glue nozzles 2 cannot automatically rotate downwards.

[0026] On both sides of the glue outlet pipe 1, there are integrally formed connecting parts 11. The end of the glue nozzle 2 is fixedly provided with a rotary joint 21. The rotary joint 21 is rotationally and sealingly connected to the connecting part 11. A rubber seal is used for installation at the rotary connection to ensure the sealing effect while enabling rotation, so that the glue nozzle 2 can rotate on the side of the glue outlet pipe 1 and avoid leakage at the connection.

[0027] The outer surface of the connecting part 11 is fixedly provided with a fixed bracket 33. The gear 39 is fixedly sleeved on the outer wall of the rotary joint 21. The gear 39 and the rack 38 are both arranged inside the fixed bracket 33. The bottom of the extraction rod 31 is fixedly connected with a T-shaped connecting piece 32. Both ends of the bottom of the T-shaped connecting piece 32 are fixedly connected with sliding rods 34. The sliding rods 34 are movably inserted into the fixed bracket 33 and are fixedly connected with the rack 38. In this way, when the extraction rod 31 is pulled outwards, the sliding rods 34 are driven to slide outwards through the T-shaped connecting piece 32, thereby driving the rack 38 to move outwards and rotatingly driving the gear 39.

[0028] The outer end of the extraction rod 31 is rotatably connected with a fixed handle 35. An opening groove 36 is provided at the top of the fixed handle 35. The end of the glue outlet pipe 1 is fixedly provided with a T-shaped shaft 37. The fixed handle 35 is movably clamped on the outer surface of the T-shaped shaft 37 through the opening groove 36. When the extraction rod 31 is pushed into the glue outlet pipe 1, the piston head 310 is moved out of the inner conical seal 12. At this time, the glue can be discharged outwards through the inner conical seal 12 into the glue nozzle 2. At this time, the fixed handle 35 is fixed by the T-shaped shaft 37 to prevent the glue from pushing the piston head 310 outwards and avoid automatic blockage.

[0029] A connecting flange 13 is fixedly installed on the top of the glue outlet pipe 1 for assembling with the reaction kettle for producing adhesives, and it is convenient to disassemble after use to clean the inside of the reaction kettle and the entire discharging device to avoid the influence of colloid solidification on subsequent use.

[0030] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above-mentioned embodiments, and what is described in the above-mentioned embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
