Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of film production, in particular to a die head disassembly and assembly structure for a capacitor film production line. Background Art
[0002] The BOPP capacitor film production line generally uses a single-layer hanger die head. After the die head is used for a certain period of time, carbon deposition will occur in the die cavity, affecting the thickness uniformity of the produced BOPP capacitor film products. Therefore, it is necessary to regularly disassemble and clean the die head to remove the internal carbon deposition and ensure the uniformity and quality of the products. According to the instructions of the original equipment manufacturer, the die head is laid down for disassembly, but in the actual process of disassembling the die head, many operation inconveniences and risks will be caused. For example, there are steel wire ropes around, which hinder the disassembly of the back screws. Hexagon keys and extended iron rods are required for the internal hexagon screws on the back. The four corners are lifted by the steel wire ropes, which hinders the normal rotation of the extended iron rod and delays the operation of disassembling the screws; during the disassembly process, high control precision of the crane is required. If the speed control is too fast or the shaking is too large, it is easy to knock and damage the most important film lip part of the die head, resulting in fatal defects in the products. Therefore, during the hoisting process, a person needs to hold a copper sheet in front of the film lip position to prevent sudden situations from knocking and damaging the film lip; during the hoisting process, it is necessary to frequently check the alignment of the die head to prevent excessive hoisting deviation; after separating the two side die cavities, the die head also needs to be flipped 180 degrees so that the die cavity surface faces up, facilitating personnel to clean. Summary of the Utility Model

[0023] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.
[0024] Reference Figures 1 to 2 The utility model provides a capacitive film production line die head disassembly structure, and makes the following embodiments:
[0025] In some embodiments, a capacitive film production line die head assembly and disassembly structure includes: a first side mold 100 and a second side mold 200, the first side mold 100 and the second side mold 200 are both provided with grooves, the first side mold 100 and the second side mold 200 are connected by screws to form a mold cavity, a film lip is formed between the first side mold 100 and the second side mold 200, and auxiliary plates 300 are removable at both the front and rear ends of the first side mold 100 and the second side mold 200.
[0026] During disassembly and assembly, the auxiliary plate 300 is installed at both ends of the first side mold 100 and the second side mold 200, and then the mold head is removed to the ground, and then the back screws are removed to avoid operation on a narrow machine platform, which makes it more convenient for personnel to remove the screws; after the first side mold 100 and the second side mold 200 are separated, the auxiliary plate 300 is used to flip them over so that the mold head lies flat, the mold cavity leaks out, and the mold cavity faces upward, which is convenient for personnel to clean.
[0027] For further improvement, the first side mold 100 is threadedly connected with a setscrew 400 that abuts against the first side mold 100. By rotating the setscrew 400, the setscrew 400 extends towards the second side mold 200, pushing the first side mold 100 and the second side mold 200 apart, and it is not easy to damage the lip film. Since the setscrew 400 advances gradually, it can apply force evenly to the second side mold 200, avoiding the impact and damage caused by instant strong force. The setscrew 400 itself is made of high-strength alloy steel, and its end is designed to be conical or spherical, so as to gradually push open the adjacent second side mold 200 during rotation while reducing damage to the contact surface.
[0028] The setscrew 400 can effectively protect the lip film from being damaged. In the traditional mold structure, if the side molds are directly pried open or impacted with great force to separate them, it is very easy to cause damage such as scratches, deformation, and even rupture to the lip film. However, by using the method of pushing open with the setscrew 400, the direct impact and damage to the lip film can be avoided by controlling the advancing speed and force of the setscrew 400. In addition, since the setscrew 400 applies force evenly, it can also ensure that the lip film remains flat and intact during the separation process.
[0029] For further improvement, two setscrews 400 are provided, and the two setscrews 400 are arranged at intervals front and back. The first side mold 100 and the second side mold 200 have a certain length, and setting multiple setscrews can evenly separate the first side mold 100 and the second side mold 200.
[0030] For further improvement, backing plates are provided at the bottoms of the first side mold 100 and the second side mold 200.
[0031] For further improvement, the auxiliary plates 300 are each provided with a lifting lug 500, and the multiple lifting lugs 500 are respectively arranged on the upper sides of the auxiliary plates 300, which is convenient for the lifting rope of the crane to be connected to the lifting lugs 500 to drive the first side mold 100 and the second side mold 200 to flip.
[0032] When it is necessary to flip the first side mold 100 and the second side mold 200 to clean the grooves or adjust the die head, the operator only needs to connect the lifting rope to the corresponding lifting lug 500, and then use a lifting device such as a crane or a hoist to slowly lift and flip the side mold.
[0033] For further improvement, multiple said lifting lugs 500 are respectively rotatably arranged on the auxiliary plate 300, enabling the lifting lugs 500 to have a rotating function and automatically adapt to the angle changes during the flipping process. Therefore, the risks such as wear and breakage of the lifting ropes caused by improper angles are reduced. The rotating lifting lugs 500 facilitate the flipping of the first side mold 100 and the second side mold 200 driven by the lifting ropes, making the grooves face upward, which is convenient for cleaning and the flipping of the mold head is smoother. During the flipping process, the rotating mechanism of the lifting lugs 500 will automatically adjust the angle to enable the side mold to complete the flipping action smoothly. After the flipping is completed, the groove surface faces upward, facilitating the cleaning and maintenance work for the operator.
[0034] For further improvement, the auxiliary plate 300 is detachably fixed by screws and can be fixed by using the original screw holes on the first side mold 100 and the second side mold 200 without the need to additionally set screw holes.
[0035] It should be noted that after the original mold head is unloaded to the ground, there will be installation screw holes, which can be used to install the auxiliary plate 300. The first side mold 100 is provided with screw holes for fixing the auxiliary plate 300.
[0036] Among them, the auxiliary plates 300 are all metal components, generally made of metal materials such as stainless steel and iron. As support plate members, the auxiliary plates 300 not only need to have sufficient load-bearing capacity but also ensure the structural stability and durability. The high-strength characteristics of metal materials enable them to bear large loads without being easily deformed or damaged.
[0037] The thickness of the auxiliary plate 300 is two centimeters to ensure strength. The two-centimeter thickness not only ensures that the plate member has sufficient rigidity but also avoids unnecessary material waste, achieving the maximization of cost-effectiveness. This thickness can effectively disperse and bear the weight from the upper structure or equipment, preventing damage caused by local stress concentration. In addition, the appropriate thickness also helps to resist external impacts and vibrations, ensuring the stability of the entire support system.
[0038] The vertical disassembly of the present utility model has several advantages compared to the horizontal disassembly:
[0039] 1. After the mold head is unloaded to the ground, the back screws can be disassembled, avoiding operations on the narrow machine table and making it more convenient for personnel to disassemble the screws.
[0040] 2. The vertical disassembly does not require a crane, eliminating the risk of damaging the die lip due to crane operation and not needing to frequently check the gap position between the two side mold heads.
[0041] 3. The vertical disassembly method is simple to operate and can improve the disassembly and assembly efficiency by 50%.
[0042] 4. After disassembling the mold head, the operation of flipping the mold head is simple.
[0043] The above has specifically described the preferred embodiments of the present utility model. However, the present invention is not limited to the embodiments. Those skilled in the art can also make various equivalent modifications or substitutions without departing from the spirit of the present utility model. These equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
