Description

Technical Field

[0001] This utility model is used for the automatic feeding of materials in the cross-linking process during the production of high-voltage power cables, specifically an automatic feeding device for cable production. Background Technology

[0002] The traditional production process for high-voltage power cables is: wire drawing—stretching—crosslinking—wrapping—metal sheath—PE sheath. VCV and CCV crosslinking processes are the core production processes for high-voltage power cables, and the vertical unloading of insulation materials in the cleanroom during the crosslinking process is the core of all core processes in high-voltage power cable production. Currently, there are various vertical unloading devices worldwide, among which the "Class 100 cleanroom and Class 100 glove box" are quite popular. However, in a Class 100 cleanroom, frequent personnel entry and exit are required for material changes, reducing the stability of the cleanliness level; in a Class 100 glove box, the limited operating space increases the risk of particulate contamination. Furthermore, both require manual operation in the unloading area, directly leading to difficulties in ensuring cleanliness. Statistics show that manual bag opening introduces over 100,000 dust particles with each operation, and wearing protective clothing increases sluggishness by 65%; especially with frequent personnel turnover, process stability fluctuations reach 30%.

[0037] Design concept: Design an automated device that covers all operational steps in the vertical material dropping process.

[0038] Example:

[0039] like Figures 1-11As shown, the present invention provides an automatic material feeding device for cable production, including a material preparation device 1, which is equipped with a bag opening device 10. The device includes a pulley bracket 101 and a bag lifting pulley group 102 located at the top. This product also includes a feeding workbench 2, a transmission device 3, a shearing support device 4, a cutting lifting device 5, an iris feeding device 6, and a discharge workbench 7. A transmission device 3 is provided between the feeding workbench 2 and the discharge workbench 7. The transmission device 3 includes a connecting hook 31, a conveyor chain 32, and a moving motor 33. The connecting hook 31 is located on the material preparation device 1. The moving motor 33 drives the connecting hook 31 to move through the conveyor chain 32. More specifically, the conveyor chain 32 is a standard 16A bent plate chain, whose ultimate tensile strength range ensures safe use. It also has a geared motor (moving motor 33) that can adjust the travel speed and accurately position the device. The discharge workbench 7 is equipped with a cutting lifting device 5 and an iris feeding device 6. The material preparation device 1 is moved from the feeding workbench 2 to the iris feeding device 6 via the transmission device 3 through the cutting lifting device 5. A shearing support device 4 is located at the bottom of the feeding workbench 2.

[0040] More specifically, the bottom of the feeding workbench 2 of this product is a fixed base 23, which is made of channel steel welded together and fixed with expansion bolts. The upper part is used to support the overall preparation frame, with a load-bearing capacity of >2t and a floor area of ​​1350mm*1200mm.

[0041] Furthermore, to facilitate material feeding and displacement, this product also includes a displacement frame 21 and a moving cart 22. The bottom of the feeding worktable 2 slides and moves through the displacement frame 21, and the material preparation device 1 slides and moves onto the feeding worktable 2 through the moving cart 22.

[0042] More specifically, the displacement frame 21 is made of welded square steel tubing and is supported by wheels on a fixed chassis 23. It can move back and forth in a directional manner by a cylinder installed at the bottom, with a moving distance of 200mm. The mobile vehicle 22 is also made of welded square steel tubing and is equipped with wheels, a load-bearing platform, a lifting bag opening suspension, a roller shutter frame, a support frame, and a strap-breaking scissor, etc., with a load-bearing capacity of >2t.

[0043] Furthermore, in order to cut the strip inside the material strip, the shearing support device 4 of this product includes a material support device 41 and a strip cutting device 42; the strip cutting device 42 includes a cutting cylinder 421, a left scissor blade 422 and a right scissor blade 423, the cutting cylinder 421 drives the left scissor blade 422 to rotate and cooperate with the right scissor blade 423 to perform the cutting action.

[0044] The strip cutting device 42 is equipped with a material support device 41 at the bottom, which is used to open the bag opening. The device is made of square steel pipe welded support structure and is equipped with bag opening lifting structure for vertical lifting. The frame includes four sets of robotic grippers and spring energy storage device, which are prepared for the automatic opening of the inner bag at the feeding port. The space can accommodate one person to stretch out and operate comfortably.

[0045] Furthermore, the cutting and lifting device 5 includes a lifting device 51 and a cutting device 52 arranged symmetrically on the left and right sides. The lifting device 51 includes a lifting cylinder 511, a lifting bracket 512, and bracket bearings 513.

The cutting device 52 includes a reciprocating cylinder 521, a cutting pressure plate 522, and a cutting knife device 523. The reciprocating cylinder 521 drives the cutting pressure plate 522, and the cutting pressure plate 522 is provided with a cutting knife device 523. Its cutting method is to cut the inner bag flat in one go, avoiding multiple cuttings that would generate debris and pollution, and achieving unified collection of waste materials.

[0046] Furthermore, to further widen the material strip opening, a support frame 81 and its opening support device 82 are provided between the cutting lifting device 5 and the iris feeding device 6. More specifically, the support frame 81 is made of welded square tubing and is installed in a fixed manner. Its function is to complete the opening transition of the opening support frame, making the opening of the opening support frame smooth, improving its service life, and ensuring the working stability of the opening support frame. Its excellent and simple structure is more conducive to the stable operation of the equipment.

[0047] Furthermore, to facilitate material unloading, the iris unloading device 6 is equipped with a symmetrically arranged lifting frame device 91 and its lifting cylinder 92. More specifically, the lifting system is composed of a lifting frame made of square tubes driven by two sets of four cylinders. Bearings are installed on the lifting frame to make the support frame roll rather than slide during movement, thus avoiding contamination inside the equipment caused by friction of the frame.

[0048] In this embodiment, the lower part of the unloading workbench 7 is provided with an iris feeding device 6, an inlet conduit 71, and an outlet conduit 72. The upper end of the inlet conduit 71 is provided with the iris feeding device 6, and the lower end is fitted into the outlet conduit 72. Figure 12 As shown, the iris dispensing device 6 is the core component of this feeding system. It is primarily made of precision-machined stainless steel and consists of a fixed template and a moving template. This allows for the opening to close. Its superior structural characteristics ensure the integrity of the inner bag, achieving docking between the inner bag and the dispensing port without damaging the inner bag. Power is supplied by a cylinder, and it has six diaphragms, each with a double precision sealing surface. Figure 13 As shown, the iris feeding device 6 of this product can also be modified to use a servo motor to drive the ring rack to open.

[0049] Furthermore, it also includes an iris adjustment cylinder 73, a cylinder mounting base 74, and an iris lifting device 75. The upper part of the cylinder mounting base 74 is connected to the iris feeding device 6 via the iris adjustment cylinder 73, and the lower part of the cylinder mounting base 74 is further connected to the iris lifting device 75. More specifically, the main body is made of stainless steel and is equipped with six cylinders and cylinder mounting bases 74, etc. Its function is to cooperate with the iris feeding device 6 to ensure a tight seal after the inner bag is closed. The cylinders are arranged in groups of three, evenly distributed circumferentially, to ensure the translational sealing of the iris mechanism.

[0050] Working principle explanation:

[0051] like Figures 2-4 As shown, the entire feeding workbench 2 is first moved horizontally to the unloading workbench 7 via the displacement frame 21 at the bottom. The material preparation device 1 on the upper moving car 22 is moved to the left above the cutting lifting device 5 via the docking transmission device 3. The cutting lifting device 5 cuts open the inner bag of the material preparation device 1 and completes the lifting. Then, the lower opening of the inner bag is fully opened by the support frame 81 and its opening support device 82.

[0052] The device is further displaced above the iris feeding device 6. The iris adjusting cylinder 73 can finely adjust the height, while the iris lifting device 75 lifts the entire iris feeding device 6 and the infeed guide tube 71 upwards. After the iris feeding device 6 is locked, the iris lifting device 75 returns to its original position, tightening the film. The iris adjusting cylinder 73 then returns to its original position to prevent the iris lifting device 75 from failing to tighten the film. It should be noted that the discharge guide tube 72 is the discharge port and is fixed, while the infeed guide tube 71 moves within the sealed environment of the discharge guide tube 72.

[0053] After the above operations, the feed tube 71 has now been inserted into the inner bag opening, and the docking work has been completed. Finally, the strip cutting device 42 is activated to cut the last strip inside the inner bag, and with the help of the bag lifting device, the material can be dropped vertically.

[0054] Some additional technologies of this product:

[0055] I. Vacuum material unloading auxiliary mechanism

[0056] The vacuum unloading auxiliary mechanism consists of a set of vacuum valves installed in the piping. These vacuum valves provide superior protection for the cleanliness of the materials. They can automatically open and close, serving as the final sealed section of the entire production line. This high level of automation ensures the equipment's information-based protection at the automation level.

[0057] II. Electrical Control System

[0058] This equipment uses a Siemens PLC as the logic control terminal, and the human-machine interface is displayed on a Kunlun Tongtai touchscreen. Each action point is equipped with a sensor, allowing real-time viewing of the I / O status of each point on the screen. A comprehensive alarm system ensures that personnel can monitor and adjust any point of the equipment from outside. Data storage and external data interfaces are also provided to ensure the equipment can be integrated into the production system in the future.

[0059] III. Purification System

[0060] 1. Protective and airtight roller shutter

[0061] The protective airtight roller shutter is made of three-proof fabric, which prevents dust during operation and maintains positive pressure inside the equipment.

[0062] 2. Positive pressure air supply system

[0063] The equipment has an air inlet. Finite element analysis and biomimetic design are used to ensure that the air inlet conforms to fluid dynamics design.

[0064] 3. Removable inner sealing plate mechanism

[0065] The interior of the equipment is sealed with stainless steel plates to minimize the possibility of the inner bag penetrating the equipment structure.

[0066] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
