Description

Technical Field

[0001] The embodiments of this disclosure relate to the field of cable processing technology, and more specifically, to a cable extruder with an easily replaceable extruder head. Background Technology

[0002] As a key piece of equipment in the wire and cable manufacturing industry, the cable extruder originated in the 1960s. Initially, it was mainly used for the production of insulation and sheathing layers of wires and cables. Early cable extruders had relatively simple structures, low levels of automation, and low production efficiency. With the continuous advancement of industrial technology, the increasing maturity of mechanical manufacturing processes, and significant progress in fields such as motor control technology and materials science, cable extruders have gradually developed towards automation and intelligence. From the initial simple manually operated equipment, they have gradually evolved into advanced production equipment with functions such as automatic feeding, precise temperature control, and automatic screw speed adjustment, greatly improving the production efficiency and product quality of wires and cables.

[0003] In actual production, the extruder head needs to be changed frequently according to different cable product specifications and process requirements. However, the extruder head replacement process of many existing cable extruders is complicated, requiring professional technicians to spend a lot of time and effort on disassembly, installation and debugging. This not only reduces production efficiency and increases labor costs, but also, if the operation is not done properly during the replacement process, it can easily damage equipment parts, further affecting the production progress and normal operation of the equipment.

[0004] Traditional cable extruders often have shortcomings in terms of cutting the output material and switching between different specifications. The output cutting component may not be able to accurately control the cutting length and cutting frequency, resulting in inconsistent material lengths after cutting, which affects subsequent processing. When switching between different orifice diameter output devices, the output switching component may have problems such as poor docking accuracy and poor sealing, which can cause material leakage, affect product quality, and make it difficult to quickly and accurately adapt to diverse production needs.

[0035] like Figures 1-4 As shown, this disclosure illustrates a cable extruder with an easily replaceable extruder head, comprising:

[0036] The extruder body 1 has a discharge port 2 at its extrusion end;

[0037] The discharge cutting assembly 3 is disposed on one side of the extruder body 1;

[0038] Discharge switching component 4 is located at discharge port 2;

[0039] The discharge cutting assembly 3 includes a discharge slide 3-1, which is connected to the discharge port 2. A support frame 3-2 is provided on the lower end face of the discharge slide 3-1. Drive frames 3-3 are provided on opposite sides of the discharge slide 3-1. A drive disk 3-4 is provided on the upper end of the drive frame 3-3. An output motor 3-5 is provided on the upper end of the drive disk 3-4. A drive cam 3-6 is provided on the output motor 3-5. A discharge grid 3-7 is provided on the lower end face of the drive disk 3-4. A cutting blade 3-8 is provided inside the discharge grid 3-7.

[0040] The discharge switching assembly 4 includes a rotating shaft 4-1, which is located on one side wall of the extruder body 1. A rotating disk 4-2 is mounted on the rotating shaft 4-1. A swing frame 4-3 is located on the side wall of the rotating disk 4-2. A discharge sleeve 4-4 is located on the swing frame 4-3. A feed port 4-5 is inserted into the discharge sleeve 4-4. A discharge extrusion screen 4-6 is located inside the feed port 4-5.

[0041] In some examples, one end of the discharge chute 3-1 is connected to the discharge port 2 of the extruder body 1. Since the internal diameter of the discharge chute 3-1 matches the diameter of the discharge port 2, the center lines of the two should be aligned during connection. A locating pin or other locating tool can be used for initial positioning. A support frame 3-2 is installed on the lower end face of the discharge chute 3-1. The lower end face of the support frame 3-2 should be flush with the bottom surface of the drive frame 3-3 to ensure the stability of the discharge chute 3-1. The support frame 3-2 is firmly fixed to the ground or workbench using bolts or welding. The discharge chute 3-1 is placed at an angle. The angle of inclination can be adjusted according to actual production needs and material characteristics. Generally, an angle between 5° and 15° is more suitable, which is conducive to the smooth sliding of materials under gravity.

[0042] Install drive frames 3-3 on opposite sides of the discharge chute 3-1. Fix the drive frames 3-3 to the ground or workbench using bolts or welding. Ensure that the two drive frames 3-3 are at the same height and parallel to each other to ensure that the drive disc 3-4 installed later can rotate smoothly. Install the drive disc 3-4 on the upper end of the drive frame 3-3. The drive disc 3-4 should be able to rotate flexibly on the drive frame 3-3. A bearing can be installed at the connection between the drive frame 3-3 and the drive disc 3-4 to reduce rotational friction. Install the motor platform 5 on the upper end of the drive disc 3-4. The motor platform 5 and the drive disc 3-4 are fixed and screwed together with bolts to ensure a firm connection and prevent loosening during equipment operation.

[0043] A discharge grid 3-7 is installed on the lower end face of the drive plate 3-4. The lower end of the discharge grid 3-7 should fit against the discharge slide 3-1 to ensure that the material can smoothly enter the discharge grid 3-7 from the discharge slide 3-1. The discharge grid 3-7 is provided with a drive cavity 3-10. The cutting blade 3-8 is embedded in the drive cavity 3-10. The cutting blade 3-8 has the same structure as the discharge grid 3-7, and a drive block 3-9 is provided on the upper end face of the cutting blade 3-8. The drive block 3-9 is connected to the drive cam 3-6 by a pin to ensure a firm connection and free movement.

[0044] Install a self-rotating shaft 4-1 on one side wall of the extruder body 1. The self-rotating shaft 4-1 should be driven to rotate by a motor. First, drill a suitable mounting hole on the side wall of the extruder body 1, then install the self-rotating shaft 4-1 in the mounting hole and support it with a bearing to ensure that the self-rotating shaft 4-1 can rotate flexibly. Install the motor that drives the self-rotating shaft 4-1 in a suitable position, and connect the motor to the self-rotating shaft 4-1 through a coupling or belt or other transmission device. Adjust the tension of the transmission device to ensure stable power transmission.

[0045] Mount the spinner 4-2 onto the spin shaft 4-1 to ensure that the spinner 4-2 can rotate freely around the spin shaft 4-1. Install the swing frame 4-3 on the side wall of the spinner 4-2. The number of swing frames 4-3 is as follows: the specific number is determined according to the actual production needs, and generally 3 to 5 is more appropriate.

[0046] like Figures 1-4 As shown, in this embodiment, a drive block 3-9 is provided on the upper end face of the cutting blade 3-8. The drive block 3-9 is connected to the drive cam 3-6 by a pin. The cutting blade 3-8 has the same structure as the discharge grid 3-7. The discharge grid 3-7 is provided with a drive cavity 3-10 inside, and the cutting blade 3-8 is embedded inside the drive cavity 3-10.

[0047] In some examples, when the output motor 3-5 drives the drive cam 3-6 to rotate, the drive cam 3-6 can drive the cutter 3-8 to reciprocate up and down in the drive cavity 3-10 of the discharge grid 3-7 through the drive block 3-9, thereby realizing the function of cutting the material.

[0048] For example, such as Figure 2 As shown, there are several swing frames 4-3, and each swing frame 4-3 is equipped with a discharge extrusion screen 4-6, and the aperture of the multiple discharge extrusion screens 4-6 is different.

[0049] In some examples, a discharge extrusion mesh 4-6 is installed inside the feed port 4-5. The discharge extrusion mesh 4-6 on multiple swing frames 4-3 has different apertures. The discharge extrusion mesh 4-6 with different apertures can be switched by rotating the self-rotating disk 4-2 according to the needs of producing cables of different specifications.

[0050] For example, such as Figure 1 As shown, the inner bottom surface of the discharge chute 3-1 is a semi-circular structure, the bottom of the cutting blade 3-8 and the discharge grid 3-7 are both semi-circular structures, and the lower end of the discharge grid 3-7 is in contact with the discharge chute 3-1.

[0051] For example, such as Figure 3 As shown, a motor platform 5 is provided on the lower end face of the output motor 3-5. The motor platform 5 is located on the upper end face of the drive disk 3-4. The motor platform 5 and the drive disk 3-4 are connected by bolts.

[0052] In some examples, the output motor 3-5 is mounted on the motor platform 5 with its lower end face in close contact with the motor platform 5. The mounting position of the output motor 3-5 is checked to ensure that its drive shaft is concentric with the central axis of the drive disk 3-4. Then, the output motor 3-5 is fixed to the motor platform 5 with bolts.

[0053] For example, such as Figure 1As shown, the inner diameter of the discharge chute 3-1 matches the diameter of the discharge port 2. The discharge chute 3-1 is inclined. The lower end face of the support frame 3-2 is flush with the bottom face of the drive frame 3-3. The self-rotating shaft 4-1 is driven to rotate by a motor. The diameter of the material passage 4-5 matches that of the discharge port 2. The positions of the material passage 4-5 and the discharge port 2 are corresponding.

[0054] For example, such as Figure 2 As shown, a discharge pipe 6 is provided at the outer end of the discharge sleeve 4-4, and a sealing sleeve 7 is provided on the outer side wall of the discharge pipe 6. The discharge pipe 6 is inserted into the discharge port 2.

[0055] In some examples, a discharge sleeve 4-4 is installed on each swing frame 4-3, a discharge pipe 6 is installed on the outer end of the discharge sleeve 4-4, and a sealing sleeve 7 is installed on the outer side wall of the discharge pipe 6. The discharge pipe 6 is inserted into the discharge port 2. The sealing sleeve 7 can ensure the sealing between the discharge pipe 6 and the discharge port 2 to prevent material leakage. A material passage 4-5 is inserted into the discharge sleeve 4-4. The diameter of the material passage 4-5 matches that of the discharge port 2 and the position corresponds to that of the material passage 2.

[0056] When in use, turn on the main power switch in the electrical control cabinet to connect the equipment power supply. At this time, the indicator light in the electrical control cabinet should light up, indicating that the power supply is on. Press the start button of the extruder body 1 to start the drive motor of the extruder body 1. Observe the motor start-up process. It should be smooth without abnormal noise and vibration. After the start-up is completed, check the operating parameters of the extruder body 1, such as screw speed and temperature, and adjust them according to the production process requirements. After the extruder body 1 is running stably, turn on the material conveying device to slowly feed the material into the hopper of the extruder body 1. Pay attention to the material feeding situation to ensure that the material can enter the extruder body 1 evenly and smoothly, and avoid the phenomenon of material interruption or excessive feeding.

[0057] After the extruder body 1 is running and the material begins to be extruded from the discharge port 2, start the output motor 3-5 of the discharge cutting assembly 3. Press the start button of the output motor 3-5, and the motor should start smoothly, driving the drive cam 3-6 to start rotating. Observe the movement of the cutting blade 3-8. The cutting blade 3-8 should move up and down in the drive chamber 3-10 of the discharge grid 3-7 under the drive of the drive cam 3-6 to cut the material extruded from the discharge port 2. According to the extrusion speed and cutting length requirements of the material, the cutting frequency of the cutting blade 3-8 is controlled by adjusting the speed of the output motor 3-5. Generally, the cutting frequency can be adjusted by a frequency converter. The adjustment range can be set between 10-100 times / minute according to the actual production situation. Check whether the length of the cut material meets the requirements. If there is a deviation, it can be adjusted by adjusting the eccentricity of the drive cam 3-6 or by replacing the drive cam 3-6 with a different specification. At the same time, observe the fit between the cutting blade 3-8 and the bottom of the discharge grid 3-7 to ensure good cutting effect and a flat material cutting surface.

[0058] When switching between different aperture sizes of the discharge extrusion mesh 4-6, start the motor that drives the rotating shaft 4-1 to rotate. Press the motor start button, and the motor will drive the rotating shaft 4-1 to start rotating, thereby causing the rotating disk 4-2 and the swing frame 4-3 mounted on it to rotate together. Observe the rotation of the rotating disk 4-2; it should be smooth and without jamming. During the rotation, according to the required aperture size of the discharge extrusion mesh 4-6, use the operating control button or manual adjustment device to align the feed port 4-5 with the discharge port 2 with the corresponding aperture size of the discharge extrusion mesh 4-6. Check the alignment of the feed port 4-5 and the discharge port 2 to ensure that their center lines coincide and that the sealing sleeve 7 is well sealed without material leakage. After the switching is completed, the extrusion effect of the material after passing through the discharge extrusion mesh 4-6 can be observed to further confirm whether the switching was successful. If uneven discharge or leakage is found, the machine should be stopped immediately for adjustment.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
