Description

Technical Field

[0001] This utility model relates to the field of detonator lead wire production technology, specifically an extrusion device for detonator lead wire production. Background Technology

[0002] Detonator leads typically consist of a positive lead and a negative lead, which are fixed together by plastic plugs and arranged in parallel. A bending design maintains spacing to prevent short circuits. The leads are usually made of copper or iron core, with an outer layer of plastic insulation to improve mechanical strength and moisture resistance. The production of this insulation material requires an extruder. However, existing extruders sometimes experience material clumping due to long-term storage. Insufficient mixing leads to uneven distribution and poor quality. Furthermore, extruder head replacement is necessary when clogged, which is cumbersome in practice and consequently affects plastic processing efficiency.

[0003] Based on this, an extrusion device for producing detonator lead wire is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] In one embodiment, such as Figures 1-4As shown, an extrusion device for producing detonator lead wire includes an extruder 1. A base 11 is fixedly connected to the bottom end of the extruder 1. A mounting seat 12 is fixedly connected to the left side of the extruder 1. A protective shell 13 is fixedly connected to the outer wall of the mounting seat 12. Mounting blocks 15 are symmetrically arranged on the right side of the extruder 1. A guide block 16 is slidably connected to the inner wall of the mounting block 15. An extrusion port 14 is fixedly connected to the outer wall of the guide block 16. The outer wall of the extrusion port 14 fits against the outer wall of the outlet end of the extruder 1. A sealing ring 17 is fixedly connected to the right side of the extruder 1. The outer wall of the sealing ring 17 is inserted into the inner wall of the extrusion port 14. A feeding mechanism 2 is provided on the upper surface of the extruder 1 near the mounting seat 12. An extrusion mechanism 3 is provided on the outer wall of the base 11 near the protective shell 13. Limiting mechanisms 4 are symmetrically arranged on the outer wall of the extruder 1 near the extrusion port 14.

[0022] In this embodiment, the feeding mechanism 2 supplies material into the extruder 1, and the extrusion mechanism 3 extrudes the material into the extruder 1 to achieve the extrusion molding effect. At the same time, the extrusion mechanism 3 stirs the material in the extruder 1 to prevent the material from clumping. When it is necessary to replace or disassemble the extrusion port 14, the extrusion port 14 can be quickly removed by removing the limiting mechanism 4 to limit the extrusion port 14 for replacement or cleaning.

[0023] In an optional embodiment, such as Figures 1-4 As shown, the feeding mechanism 2 includes a storage tank 21. The outlet of the storage tank 21 passes through the outer wall of the extruder 1 and communicates with its inner cavity. A solenoid valve is installed on the outlet pipe of the storage tank 21, and the outer wall of the storage tank 21 is provided with a metering scale. A motor 22 is fixedly connected to the top of the storage tank 21. A rotating rod 23 is fixedly connected to the output end of the motor 22 through the outer wall of the storage tank 21. A stirring rod 24 is fixedly connected to the outer wall of the rotating rod 23. When the motor 22 is started, the material in the storage tank 21 is heated and stirred. Then, by opening the solenoid valve at the outlet, the material in the storage tank 21 enters the inner cavity of the extruder 1.

[0024] In an optional embodiment, such as Figures 1-4As shown, the extrusion mechanism 3 includes a second motor 31. The outer wall of the second motor 31 is fixedly connected to the outer wall of the base 11. The output end of the second motor 31 is driven by a synchronous belt 32 via a transmission wheel. The inner wall of the synchronous belt 32 near the mounting base 12 is driven by a rotating shaft 33 via a transmission wheel. The outer wall of the rotating shaft 33 is rotatably connected to the inner wall of the mounting base 12. The outer wall of the rotating shaft 33 is driven by a second synchronous belt 34 via a transmission wheel. The inner wall of the second synchronous belt 34 away from the rotating shaft 33 is driven by a rotating rod 35 via a transmission wheel. The outer wall of the rotating rod 35 is rotatably connected to the inner wall of the extruder 1. Spiral blades 36 are fixedly connected to the outer wall of extruder 1. Stirring rods 37 are evenly distributed on the outer wall of extruder 1. Motor 2 31 drives synchronous belt 1 32 to rotate, which in turn drives shaft 33 to rotate. Shaft 33 drives synchronous belt 2 34 to rotate, which in turn drives extruder 2 35 to rotate. This causes extruder 2 35 to drive spiral blades 36 and stirring rods 37 to rotate. Spiral blades 36 push and extrude the material entering the inner cavity of extruder 1. At the same time, stirring rods 37 stir the material in extruder 1 to prevent material from clumping and affecting subsequent extrusion.

[0025] In an optional embodiment, such as Figures 1-4 As shown, the outer wall of the spiral blade 36 is clearance-fitted with the inner cavity of the extruder 1, and the diameter of the spiral blade 36 is adapted to the diameter change of the inner cavity of the extruder 1, so that no motion interference will occur when the spiral blade 36 rotates.

[0026] In an optional embodiment, such as Figures 1-4 As shown, the stirring rod 37 is fishbone shaped, which makes the stirring rod 37 more effective in stirring the material in the extruder 1.

[0027] In an optional embodiment, such as Figures 1-4As shown, the limiting mechanism 4 includes a fixed block 41. The outer wall of the fixed block 41 is fixedly connected to the outer wall of the extruder 1, and the outer wall of the fixed block 41 is slidably connected to the outer wall of the extrusion port 14. A connecting block 45 is fixedly connected to the fixed block 41 near the outer wall of the extruder 1. An insert block 43 is slidably connected to the inner cavity of the fixed block 41. A spring 42 is fixedly connected to the outer wall of the insert block 43, and the end of the spring 42 is fixedly connected to the inner cavity of the fixed block 41. A limiting block 44 is inserted into the outer wall of the insert block 43. The outer wall of the limiting block 44 is slidably connected to the inner walls of the fixed block 41 and the connecting block 45. The outer wall of the limiting block 44 is inserted into the inner wall of the extrusion port 14. A pull rod 46 is fixedly connected to the end of the limiting block 44. The outer wall of the pull rod 46 is slidably connected to the inner wall of the connecting block 45. A slider is fixedly connected to the outer wall of the limiting block 44. 47. The outer wall of slider 47 is slidably connected to the inner wall of connecting block 45. A slide rod 48 is slidably connected to the inner wall of slider 47. One end of slide rod 48 is fixedly connected to the inner cavity of connecting block 45. A second spring 49 is sleeved on the outer wall of slide rod 48. One end of spring 49 is fixedly connected to the outer wall of slider 47, and the other end is fixedly connected to the inner cavity of connecting block 45. By pulling insert block 43, spring 42 is contracted, so that the outer wall of insert block 43 is no longer inserted into the inner wall of limit block 44. Then, pull rod 46 can be pulled to move limit block 44 synchronously, so that limit block 44 drives slider 47 to slide on the outer wall of slide rod 48, so that spring 49 is contracted, so that the outer wall of limit block 44 is no longer inserted into the inner wall of extrusion port 14. Then, extrusion port 14 can be removed for cleaning or replacement.

[0028] In an optional embodiment, such as Figures 1-4 As shown, the insert block is L-shaped, and the vertical part of the insert block is 10-20mm smaller than the width of the horizontal part, so that when the insert block 43 is pulled, the insert block 43 will not come out of the inner cavity of the fixing block 41.

[0029] In an optional embodiment, such as Figures 1-4 As shown, the pull rod 46 is T-shaped, which makes it easier to pull the pull rod 46 and also makes it easier to fix the pull rod 46.

[0030] The above embodiment discloses an extrusion device for producing detonator lead wire. When the outer insulation layer of the detonator lead wire needs to be produced, motor 22 is started to heat and stir the material in the storage tank 21. Then, the solenoid valve at the discharge port is opened, allowing the material in the storage tank 21 to enter the inner cavity of the extruder 1. Motor 31 drives synchronous belt 32 to rotate, which in turn drives shaft 33 to rotate. Shaft 33 drives synchronous belt 34 to rotate, which in turn drives rotating rod 35 to rotate. Rotating rod 35 then drives spiral blades 36 and stirring support rod 37 to rotate. Spiral blades 36 push and extrude the material entering the inner cavity of the extruder 1. Simultaneously, stirring rod 37 stirs the material in the extruder 1 to prevent material agglomeration, which would affect subsequent extrusion. If the extrusion port becomes blocked, it needs to be disassembled. When the insert block 43 is pulled, the spring 42 contracts, so that the outer wall of the insert block 43 is no longer inserted into the inner wall of the limiting block 44. Then the pull rod 46 can be pulled, so that the limiting block 44 moves synchronously, so that the limiting block 44 drives the slider 47 to slide on the outer wall of the slide rod 48, so that the spring 49 contracts, thus so that the outer wall of the limiting block 44 is no longer inserted into the inner wall of the extrusion port 14. Then the extrusion port 14 can be removed for cleaning or replacement. In summary, the feeding mechanism 2 provides material into the extruder 1, and the extrusion mechanism 3 extrudes the material entering the extruder 1, so as to achieve the extrusion molding effect. At the same time, the extrusion mechanism 3 stirs the material in the extruder 1 to prevent the material from clumping. When it is necessary to replace or disassemble the extrusion port 14, the limiting mechanism 4 can be removed to limit the extrusion port 14, so that the extrusion port 14 can be quickly removed for replacement or cleaning.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
