Description

Technical Field

[0001] This utility model relates to the field of extrusion machine technology, and in particular to an extrusion machine for wires with a cleaning structure. Background Technology

[0002] Wire extrusion machines are used to melt insulating materials at high temperatures and then uniformly extrude them onto the conductors of wires to form an insulation layer with specific properties.

[0003] However, during the initial startup of the extrusion machine, the heating system needs time to reach a stable operating temperature, which may result in incompletely melted gel-like substances. For example, Chinese invention patent application number CN202310386296.4 describes an electrical wire coating device, including a coating device body. A feed inlet is fixedly installed on one side of the upper end face of the coating device body, and a raw material pipe is fixedly installed on one side of the front face of the coating device body. An extrusion head is fixedly installed on one side of the outer surface of the raw material pipe. The coating device body is used to melt the adhesive at high temperature and then transport it to the extrusion head through the raw material pipe. If the adhesive melted by the coating device body is not completely melted, these incompletely melted gel-like substances will directly participate in the extrusion process of the electrical wire, causing defects on the surface of the wire. This seriously affects the electrical and mechanical properties of the wire, reduces the overall quality of the wire, and may even lead to safety hazards during use. Utility Model Content

[0004] To address the problem that incompletely melted gel-like material can directly participate in the wire extrusion process, causing defects on the wire surface, this invention provides a wire extrusion machine with a cleaning structure.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] An embodiment of this utility model provides a wire extrusion machine with a cleaning structure, comprising:

[0009] A clamping device, comprising two clamping arms, wherein when the extrusion head abuts against the discharge head, the two clamping arms can clamp the discharge head and the extrusion head;

[0010] When the clamping device releases the discharge head from the extrusion head and the extrusion head moves away from the discharge head, the extrusion machine body is in a cleaning state; when the extrusion head is connected to the discharge head and the clamping device clamps the discharge head and the extrusion head, the extrusion machine body is in a working state.

[0011] According to some embodiments of the present invention, the discharge head is provided with a first annular groove, the extrusion head is provided with a second annular groove, and the clamping arm is provided with a clamping groove. When the clamping device clamps the discharge head and the extrusion head, the two side walls of the clamping groove are respectively embedded in the first annular groove and the second annular groove.

[0012] According to some embodiments of the present invention, the sidewall of the first annular groove near the extrusion head and the sidewall of the second annular groove near the discharge head are both formed with slope portions. In the direction from the extrusion head to the discharge head, the diameter of the slope portion on the extrusion head gradually increases; in the direction from the discharge head to the extrusion head, the diameter of the slope portion on the discharge head gradually increases.

[0013] According to some embodiments of the present invention, the clamping device further includes a fastening structure for fastening the two clamping arms.

[0014] According to some embodiments of the present invention, the fastening structure includes a screw rotatably connected to one of the clamping arms and a nut screwed to the screw. The other clamping arm is provided with a fastening groove. When the screw passes through the fastening groove, the nut can prevent the screw from disengaging from the fastening groove.

[0015] According to some embodiments of the present invention, the clamping device further includes a fixed base fixed to the body of the extruder, and the clamping arm is rotatably connected to the fixed base.

[0016] According to some embodiments of the present invention, the moving device includes a rotating rod assembly rotatably connected to the extruder body, and the extrusion head is rotatably connected to the rotating rod assembly.

[0017] According to some embodiments of the present invention, the rotating rod assembly includes a first rotating rod, a second rotating rod, and a third rotating rod.

[0018] According to some embodiments of the present invention, a wire extrusion machine with a cleaning structure further includes a filter cover, the filter cover having a plurality of filter holes, and the discharge head having a placement groove for placing the filter cover.

[0019] This invention has at least the following beneficial effects: By using a movable discharge head and an extrusion head, along with the cooperation of a moving device and a clamping device, this invention can clean up the incompletely melted gel at the discharge head by separating the discharge head and the extrusion head. Normal operation can only begin after the gel at the discharge head is completely melted, thus preventing these impurities from entering the extrusion head and participating in the wire extrusion process. This effectively solves the problem of surface defects, decreased electrical and mechanical properties of wires caused by incompletely melted gel in the initial stage of operation of existing wire extrusion machines.

[0025] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0026] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0028] An embodiment of this utility model provides a wire extrusion machine with a cleaning structure, such as... Figure 1-5 As shown, it includes:

[0029] The extruder body 100 has a cleaning state and a working state. The extruder body 100 includes a discharge head 110 and an extrusion head 120.

[0030] The moving device 300 connects the discharge head 110 and the extrusion head 120. The extrusion head 120 can move away from or closer to the discharge head 110.

[0031] The clamping device 200 includes two clamping arms 210. When the extrusion head 120 abuts against the discharge head 110, the two clamping arms 210 can clamp the discharge head 110 and the extrusion head 120.

[0032] When the clamping device 200 releases the discharge head 110 and the extrusion head 120 and the extrusion head 120 moves away from the discharge head 110, the extruder body 100 is in a cleaning state; when the extrusion head 120 is connected to the discharge head 110 and the clamping device 200 clamps the discharge head 110 and the extrusion head 120, the extruder body 100 is in a working state.

[0033] The extruder body 100 includes a discharge head 110 and an extrusion head 120, which are movably connected. This design facilitates their separation when cleaning is required. The extruder body 100 has a cleaning state and a working state.

[0034] Cleaning state: When the clamping device 200 releases the discharge head 110 and the extrusion head 120, and the extrusion head 120 moves to a position away from the discharge head 110, the extruder is in the cleaning state. In this state, unmelted adhesive coming out of the discharge head 110 can be directly removed, preventing this adhesive from entering the extrusion head 120. After observing that the adhesive coming out of the discharge head 110 has reached a normal melting state, the wire extrusion operation can begin.

[0035] Working status: When the extrusion head 120 is connected to the discharge head 110 and the clamping device 200 clamps them, the extrusion machine is in working status and can perform wire extrusion operations normally.

[0036] The clamping device 200 includes two clamping arms 210, which are used to clamp the discharge head 110 and the extrusion head 120, ensuring that they are tightly connected in the working state and preventing loosening or separation during the extrusion process. The clamping device 200 can clamp and release the device mechanically or hydraulically. In the cleaning state, the clamping device 200 is released, allowing the discharge head 110 and the extrusion head 120 to be separated; in the working state, the clamping device 200 is clamped, ensuring that the discharge head 110 and the extrusion head 120 are tightly connected.

[0037] The extrusion head 120 can be moved away from or closer to the discharge head 110 via the moving device 300. The moving device 300 can be driven by a hydraulic cylinder, pneumatic cylinder, or manual push rod to achieve precise movement of the extrusion head 120. This design allows the extruder to quickly switch between cleaning and working states.

[0038] The movably connected discharge head 110 and extrusion head 120, along with the coordination of the moving device 300 and clamping device 200, allow the extruder to easily separate the discharge head 110 and extrusion head 120 during cleaning, facilitating the removal of unmelted adhesive. This design enables the extruder to quickly switch between cleaning and operating states, reducing cleaning and maintenance time, improving equipment efficiency, and ensuring high-quality electrical components.

[0039] In some embodiments, the discharge head 110 is provided with a first annular groove 111, the extrusion head 120 is provided with a second annular groove 121, and the clamping arm 210 is provided with a clamping groove 220. When the clamping device 200 clamps the discharge head 110 and the extrusion head 120, the two side walls of the clamping groove 220 are respectively embedded in the first annular groove 111 and the second annular groove 121.

[0040] The first annular groove 111 is located at the discharge head 110 and is a groove surrounding the outer periphery of the discharge head 110. The second annular groove 121 is located at the extrusion head 120 and is a groove surrounding the outer periphery of the extrusion head 120. The clamping groove 220 is located on the clamping arm 210 and is used to cooperate with the annular groove.

[0041] When the clamping device 200 clamps the discharge head 110 and the extrusion head 120, the two side walls of the clamping groove 220 are respectively embedded in the first annular groove 111 and the second annular groove 121. This design ensures that the clamping device 200 can firmly clamp the discharge head 110 and the extrusion head 120 together, preventing them from loosening or separating during operation. Through the engagement of the annular groove and the clamping groove 220, the clamping device 200 can apply pressure evenly, making the discharge head 110 and the extrusion head 120 tightly connected, while avoiding damage caused by excessive local force. The matching design of the annular groove and the clamping groove 220 is simple, but can achieve a reliable clamping function. This design makes the operation of the clamping device 200 more intuitive, and the operator can quickly complete the clamping or releasing action. Through the engagement method, the clamping device 200 can better adapt to the shape of the discharge head 110 and the extrusion head 120, ensuring their stability during operation.

[0042] The principle of this embodiment is as follows:

[0043] Cleaning status: When the extruder needs to be cleaned, the clamping device 200 is released, the clamping groove 220 exits from the annular groove, and the discharge head 110 and the extrusion head 120 can be separated.

[0044] Working status: After cleaning, the extrusion head 120 is connected to the discharge head 110, and the clamping groove 220 of the clamping device 200 is embedded in the first annular groove 111 and the second annular groove 121 to complete the clamping action and put the extruder into working status.

[0045] In some embodiments, a sealing ring is provided between the annular groove and the clamping groove 220. The sealing ring prevents impurities from entering, further improving the reliability and service life of the equipment.

[0046] Furthermore, the sidewall of the first annular groove 111 near the extrusion head 120 and the sidewall of the second annular groove 121 near the discharge head 110 are both formed with slope portions 112. In the direction from the extrusion head 120 to the discharge head 110, the diameter of the slope portion 112 on the extrusion head 120 gradually increases; in the direction from the discharge head 110 to the extrusion head 120, the diameter of the slope portion 112 on the discharge head 110 gradually increases.

[0047] Both the discharge head 110 and the extrusion head 120 are provided with ramp portions 112. When the clamping device 200 clamps the discharge head 110 and the extrusion head 120, the two side walls of the clamping groove 220 respectively abut against the ramp portions 112. This design creates a wedge-shaped fit between the clamping groove 220 and the ramp portions 112. The diameter of the ramp portions 112 gradually increases, so that when the clamping groove 220 abuts against the ramp portions 112, the clamping force gradually increases with the clamping action of the clamping device 200 through the wedge effect, thereby achieving a more secure clamping effect. The design of the ramp portions 112 also helps the discharge head 110 and the extrusion head 120 to automatically align during the clamping process, reducing the problem of uneven clamping caused by positional deviation. The wedge-shaped fit makes the clamping device 200 more stable in the working state, and the discharge head 110 and the extrusion head 120 are not easy to loosen even under vibration or impact.

[0048] In some embodiments, the clamping device 200 further includes a fastening structure 230 for fastening the two clamping arms 210.

[0049] The main function of the fastening structure 230 is to securely fix the two clamping arms 210 together, ensuring that the clamping arms 210 will not loosen or shift when clamping the discharge head 110 and the extrusion head 120. This design improves the overall rigidity of the clamping device 200, thereby better transmitting the clamping force and ensuring a tight connection between the discharge head 110 and the extrusion head 120 in the working state. The fastening structure 230 can take various forms, including:

[0050] Bolted connection: The two clamping arms 210 are secured together by bolts. Bolted connection is a simple and reliable method, and the tightening force between the clamping arms 210 can be adjusted by tightening the bolts.

[0051] Snap-fit ​​structure: The snap-fit ​​design allows the two clamping arms 210 to snap together quickly. The advantage of the snap-fit ​​structure is its ease of operation, enabling the clamping arms 210 to be fixed in a short time.

[0052] Hydraulic or pneumatic fastening: The two clamping arms 210 are pressed together using the thrust of a hydraulic or pneumatic cylinder. This design enables automated fastening operations.

[0053] Furthermore, the fastening structure 230 includes a screw 231 rotatably connected to one of the clamping arms 210 and a nut 232 screwed to the screw 231. The other clamping arm 210 is provided with a fastening groove 233. When the screw 231 passes through the fastening groove 233, the nut 232 can prevent the screw 231 from disengaging from the fastening groove 233.

[0054] The width of nut 232 is greater than the overall width of the fastening groove 233. When the screw 231 passes through the fastening groove 233, tightening nut 232 restricts the screw 231 from disengaging from the fastening groove 233, thus firmly fixing the two clamping arms 210 together. By rotating nut 232, nut 232 is tightened onto screw 231 until it contacts the edge of the fastening groove 233, thereby restricting the movement of screw 231. When clamping device 200 needs to clamp discharge head 110 and extrusion head 120, the two clamping arms 210 are connected together by fastening structure 230. By tightening nut 232, screw 231 is fixed in the fastening groove 233, and the two clamping arms 210 are firmly fixed together, thus achieving the clamping function. When it is necessary to release clamping device 200, nut 232 is rotated in the opposite direction to release nut 232 from screw 231. The screw 231 can move freely, thereby releasing the fixation on the two clamping arms 210. The engagement of the screw 231 and the nut 232 is a common mechanical connection method, with a simple structure that is easy to manufacture and maintain. Tightening the screw 231 by the nut 232 can achieve a reliable fastening effect, ensuring the stability of the clamping device 200 in the working state.

[0055] In some embodiments, the clamping device 200 further includes a fixed base 234 fixed to the extruder body 100, and the clamping arm 210 is rotatably connected to the fixed base 234.

[0056] The clamping arm 210 is rotatably connected to the fixed base 234, allowing the clamping arm 210 to rotate freely within a certain range. One end of the clamping arm 210 is mounted on the fixed base 234 via a shaft hole, ensuring smooth rotation of the clamping arm 210. The clamping arm 210 can rotate around the fixed base 234, allowing the operator to easily move the clamping arm 210 to the connection point between the discharge head 110 and the extrusion head 120 for clamping or releasing operations.

[0057] In some embodiments, the mobile device 300 includes a rotating rod assembly 310 rotatably connected to the extruder body 100, and the extrusion head 120 is rotatably connected to the rotating rod assembly 310.

[0058] The rotating rod assembly 310 is rotatably connected to the extruder body 100 and also to the extrusion head 120. This design allows the extrusion head 120 to move freely within a certain range, thus enabling the extruder to switch between cleaning and working states. The rotating rod assembly 310 is connected to the extruder body 100 and the extrusion head 120 via a rotatable connection, which can be a shaft-hole fit, bearing connection, or other similar mechanical connection method. One end of the rotating rod assembly 310 is rotatably connected to the extruder body 100 and can be mounted in a fixed position on the extruder body 100 via a bearing. This connection method allows the rotating rod assembly 310 to rotate freely around its axis. The extrusion head 120 can move closer to or further away from the discharge head 110 by rotating the rotating rod assembly 310. The rotating rod assembly 310 can be composed of multiple rotating rod segments connected by joints or bearings to form a foldable or telescopic structure to adapt to different working requirements. By rotating the rotating rod assembly 310, the extrusion head 120 can be easily moved to the cleaning or working position, allowing operators to easily clean and maintain the equipment. The design of the rotating rod assembly 310 effectively utilizes space, enabling the extrusion head 120 to be moved to a suitable position during cleaning, avoiding interference with other equipment or components. The rotating rod assembly 310 has a simple structure, is easy to maintain and replace, and reduces equipment maintenance costs.

[0059] Furthermore, the rotating rod assembly 310 includes a first rotating rod 311, a second rotating rod 312, and a third rotating rod 313. The first rotating rod 311 is rotatably connected to the extruder body 100, the second rotating rod 312 is rotatably connected to the first rotating rod 311, the third rotating rod 313 is rotatably connected to the second rotating rod 312, and the extrusion head 120 is rotatably connected to the third rotating rod 313.

[0060] The connection between each rotating rod segment and between the rotating rod and the extrusion head 120 can be achieved through the fit of shafts and holes, which is simple and reliable. Alternatively, bearing connections can be used, which reduce friction and improve rotational flexibility and lifespan. Hinged connections, similar to door hinges, can also be used, allowing the rotating rod to rotate freely within a certain angle range. The multi-segment design allows the extrusion head 120 to move freely in multiple directions, better adapting to different working positions and cleaning needs. This design effectively utilizes space, allowing the extrusion head 120 to be moved to a suitable position during cleaning, avoiding interference with other equipment or components.

[0061] In some embodiments, a wire extrusion machine with a cleaning structure further includes a filter cover 400, the filter cover 400 having a plurality of filter holes 410, and the discharge head 110 having a placement groove 113 for placing the filter cover 400.

[0062] like Figure 5 As shown, the filter cover 400, through its filter holes 410, can effectively filter impurities, particles, or debris generated during the extrusion process, preventing these impurities from entering the wire extrusion material and thus improving wire quality. The filter cover 400 can reduce wear on the internal components of the extruder caused by impurities, extending the equipment's service life. The design of the filter cover 400 makes cleaning the extruder easier; the filter cover 400 can be quickly removed to clean out impurities and maintain the cleanliness of the equipment's interior. The discharge head 110 is provided with a placement groove 113 for placing the filter cover 400, a design that allows for easy installation and removal of the filter cover 400. The shape and size of the placement groove 113 match the shape and size of the filter cover 400, ensuring that the filter cover 400 is stably fixed to the discharge head 110 after installation.

[0063] The working process of this embodiment is as follows:

[0064] Installation process: Before the extruder starts working, place the filter cover 400 in the placement slot 113 of the discharge head 110 and ensure that the filter cover 400 is installed firmly.

[0065] Working process: During the extrusion process, when the material passes through the filter cover 400, impurities are intercepted by the filter holes 410, and the pure material continues to enter the extrusion head 120 through the discharge head 110.

[0066] Cleaning process: When the extruder needs to be cleaned, the operator can quickly remove the filter cover 400, clean the impurities inside, and then reinstall the filter cover 400 to restore the equipment to working condition.

Therefore, those skilled in the art should understand that the foregoing description of various embodiments of the present invention is for illustrative purposes only, and not intended to limit the present invention as defined by the appended claims and their equivalents.
