Description

Technical Field

[0001] This utility model relates to the field of co-extrusion molding, specifically a co-extrusion molding device for cables and flexible flat cables. Background Technology

[0002] Co-extrusion molding of cables and flexible flat cables refers to the process of simultaneously extruding and fusing materials related to cables and flexible flat cables together through a specific co-extrusion molding device to form a composite material product with a multi-layer structure. The materials required for cables (such as insulation materials) and the materials required for flexible flat cables (such as flexible substrates) are melted and then combined in a pre-set structure and sequence within a co-extrusion die. Under the action of pressure and temperature, the materials of each layer are tightly bonded, ultimately forming a multi-layer composite product that possesses the characteristics and functions of both cables and flexible flat cables.

[0003] In existing technologies, multiple materials are typically melted and co-extruded to create composite materials. Co-extruding cables and flexible flat cables not only effectively reduces material waste but also significantly improves the quality and safety of the finished product. Generally, when co-extruding cables and flexible flat cables, a co-extrusion molding machine is used to extrude the molten cable, and a cutter is used to cut it into sections for subsequent use and storage. During cutting, one end of the extruded cable is usually inserted into the cutter, and tools such as transfer rollers are used to wind and pull out the extruded cable. However, when inserting the extruded cable into the cutter, the cable is prone to slant cuts or deformation due to its own shaking, insufficient tension, and vibration during the transfer process, which affects the normal use of the cable after molding and extrusion. Utility Model Content

[0004] To address the shortcomings of existing technologies, when the extruded cable is inserted into the cutter, the cable is prone to slant cuts and deformations due to its own shaking, insufficient sturdiness, vibration, etc. during transmission, which in turn affects the normal use of the cable after forming and extrusion. This utility model proposes a co-extrusion forming device for cables and flexible flat cables.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a co-extrusion molding device for cables and flexible flat cables, including a co-extrusion molding machine body, a cutter body is provided on one side of the co-extrusion molding machine body, a mounting frame is fixedly connected to one side of the cutter body, and a limiting mechanism is provided on one side of the mounting frame.

[0006] The limiting mechanism includes a mounting plate, the surface of which is fixedly connected to one side of a mounting frame. A cylinder is fixedly connected to one side of the mounting plate, and a movable plate is fixedly connected to the output end of the cylinder. A mounting rod is rotatably connected to the inner cavity of the movable plate, and a rotating plate is rotatably connected to the surface of the mounting rod. A connecting rod is rotatably connected to the inner cavity of the rotating plate, and a movable block is rotatably connected to the surface of the connecting rod. A limit component is provided on one side of the movable block, and a limiting block is fixedly connected to one side of the movable block.

[0007] Preferably, the limiting component includes a fixed block, one side of which is fixedly connected to one side of the moving block, and a limiting block is fixedly connected to one side of the mounting plate, with the inner cavity of the fixed block slidably connected to the surface of the limiting block.

[0008] Preferably, a limiting groove is formed on one side of the mounting plate, and a slider is fixedly connected to one side of the fixing block, with the surface of the slider slidably connected to the inner cavity of the limiting groove.

[0009] Preferably, a mounting groove is provided on one side of the limiting block, and a rotating wheel is rotatably connected to the inner cavity of the mounting groove.

[0010] Preferably, a limiting ring block is fixedly connected to the surface of the mounting rod, and one side of the limiting ring block is rotatably connected to one side of the rotating plate.

[0011] Preferably, a fixing sleeve is fixedly connected to one side of the mounting plate, and a fixing rod is fixedly connected to one side of the movable plate, with the inner cavity of the fixing sleeve slidably connected to the surface of the fixing rod.

[0012] Preferably, a rubber layer is movably bonded to the surface of the rotating wheel, and a limit rod is rotatably connected to the inner cavity of the mounting groove, with the surface of the limit rod rotatably connected to the inner cavity of the rotating wheel.

[0013] The advantages of this utility model are:

[0014] This invention utilizes a cylinder to smoothly drive a moving plate, which in turn pulls a rotating plate and a moving block via a mounting rod. This allows the moving block to move a limiting block and a mounting groove, and after moving a certain distance, it limits and clamps the co-extruded cable. This effectively reduces the poor cutting effect caused by vibration or shaking when cutting the co-extruded cable, increasing the stability of cutting the co-extruded cable. It also solves the problem that when the extruded cable is inserted into the cutter, the cable is prone to slant cuts or deformation due to its own shaking, insufficient straightening force, or vibration during transmission, which affects the normal use of the cable after forming and extrusion.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0025] This application discloses a co-extrusion molding apparatus for cables and flexible flat cables. (Refer to...) Figure 1 and Figure 3 A co-extrusion molding device for cables and flexible flat cables includes a co-extrusion molding machine body 1, a cutter body 2 is provided on one side of the co-extrusion molding machine body 1, a mounting frame 3 is fixedly connected to one side of the cutter body 2, and a limiting mechanism 4 is provided on one side of the mounting frame 3.

[0026] The limiting mechanism 4 includes a mounting plate 401, the surface of which is fixedly connected to one side of the mounting frame 3. A cylinder 402 is fixedly connected to one side of the mounting plate 401. A movable plate 403 is fixedly connected to the output end of the cylinder 402. A mounting rod 404 is rotatably connected to the inner cavity of the movable plate 403. A rotating plate 405 is rotatably connected to the surface of the mounting rod 404. A connecting rod 406 is rotatably connected to the inner cavity of the rotating plate 405. A movable block 407 is rotatably connected to the surface of the connecting rod 406. A limit component 409 is provided on one side of the movable block 407. A limiting block 408 is fixedly connected to one side of the movable block 407.

[0027] The co-extrusion molding machine body 1 can convey and extrude the molten cable and flexible flat cable material. The extruded cable can be smoothly pulled into the interior of the cutter body 2. The cable is cut by the external transmission roller. The cutting of the cutter body 2 is mainly achieved by the operation of the motor and other equipment to drive the cutting blade to move back and forth to cut the formed cable. The co-extrusion molding machine body 1, the cutter body 2 and the external transmission roller are all existing technologies in this field, so the specific working principle will not be elaborated here.

[0028] The cutter body 2 can be installed and fixed on the mounting plate 401 via the mounting bracket 3. The mounting plate 401 can be connected to the moving plate 403 via the cylinder 402. The mounting rod 404 installed inside the moving plate 403 can be connected to the connecting rod 406 via the rotating plate 405. The rotating plate 405 can rotate on the surface of the connecting rod 406. While the moving block 407 is connected to the connecting rod 406, the limiting component 409 can restrict the moving block 407, allowing the moving block 407 to slide smoothly on one side of the mounting plate 401. The rotation of the rotating plate 405 can pull or push the moving block 407 via the connecting rod 406, so that the moving block 407 can drive the limiting block 408 to slide together when it moves, thereby achieving the limiting and clamping of the extruded cable.

[0029] Reference Figure 4 and Figure 5The limiting component 409 includes a fixed block 4091, one side of which is fixedly connected to one side of the moving block 407. A limiting block 4092 is fixedly connected to one side of the mounting plate 401. The inner cavity of the fixed block 4091 is slidably connected to the surface of the limiting block 4092. The moving block 407 can connect to the fixed block 4091, while the mounting plate 401 can connect to the limiting block 4092. At the same time, the limiting block 4092 can limit the moving block 407 through the fixed block 4091, so that the moving block 407 can move smoothly and stably when pushed or pulled by the rotating plate 405.

[0030] Reference Figure 5 and Figure 6 A limiting groove 10 is provided on one side of the mounting plate 401, and a slider 11 is fixedly connected to one side of the fixing block 4091. The surface of the slider 11 is slidably connected to the inner cavity of the limiting groove 10. The cooperation between the limiting groove 10 and the slider 11 can further increase the stability and smoothness of the fixing block 4091 when sliding on one side of the mounting plate 401, thereby reducing the possibility that the moving block 407 and the fixing block 4091 cannot move smoothly and stably due to shaking during sliding.

[0031] Reference Figure 4 and Figure 5 The limiting block 408 has an installation groove 5 on one side. The inner cavity of the installation groove 5 is rotatably connected to a rotating wheel 6. The limiting block 408 can connect to the rotating wheel 6 through the installation groove 5. The rotating wheel 6 not only reduces wear when clamping the extruded cable, but also increases the stability of the cable during transmission.

[0032] Reference Figure 5 and Figure 6 A limiting ring 9 is fixedly connected to the surface of the mounting rod 404. One side of the limiting ring 9 is rotatably connected to one side of the rotating plate 405. The limiting ring 9 can restrict the rotation of the rotating plate 405, so that the rotating plate 405 can be stable enough when rotating on the surface of the mounting rod 404. The rotating plate 405 is not easy to slip or deviate during rotation, thereby increasing the stability of the rotating plate 405 during use.

[0033] Reference Figure 3 and Figure 4 A fixing sleeve 8 is fixedly connected to one side of the mounting plate 401, and a fixing rod 7 is fixedly connected to one side of the moving plate 403. The inner cavity of the fixing sleeve 8 is slidably connected to the surface of the fixing rod 7. The setting of the fixing rod 7 and the fixing sleeve 8 allows the movement of the moving plate 403 to be smoothly restricted by the connection between the fixing rod 7 and the fixing sleeve 8 when the moving plate 403 is moved by the operation of the cylinder 402, thereby increasing the stability of the moving plate 403 when it moves.

[0034] Reference Figure 3 and Figure 4 The surface of the rotating wheel 6 is movably bonded with a rubber layer 12, and the inner cavity of the mounting groove 5 is rotatably connected to a limit rod 13. The surface of the limit rod 13 is rotatably connected to the inner cavity of the rotating wheel 6. The rubber layer 12 can further reduce the wear on the surface of the cable when clamping the formed cable, and the limit rod 13 can increase the stability of the mounting groove 5 during use and rotation, making it less prone to shaking during use.

[0035] Working principle: The operator adds molten cable and flexible flat cable material into the co-extrusion molding machine body 1. The co-extrusion molding machine body 1 conveys and extrudes the molten cable and flexible flat cable material. The cable is then pulled into the cutter body 2, passing through the mounting plate 401 and the moving plate 403. The shaped cable is then transported by the transmission rollers inside the cutter body 2. During this transport, the operator can adjust the positions of the mounting groove 5 and the limiting block 408 according to the diameter of the shaped cable. When adjusting their positions, the operator can activate the cylinder 402, which smoothly drives the moving plate 403. The movable plate 403 moves, and when it moves, it can pull the rotating plate 405 through the mounting rod 404. When the rotating plate 405 is pulled, it can smoothly pull the moving block 407 through the connecting rod 406. When the moving block 407 is pulled, it will move along the surface of the limiting block 4092, and in the process of moving, it will drive the limiting block 408 and the mounting groove 5 to move together. When the mounting groove 5 moves to a certain distance, it can smoothly limit and slightly clamp the formed cable, thereby reducing the shaking or vibration of the formed cable when it is transmitted, so that the cutter body 2 can cut the formed cable more smoothly and stably.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
