Description

Technical Field

[0001] The utility model relates to the technical field of die head maintenance tools, in particular to a die head disassembly and assembly auxiliary device. Background Art

[0002] In the film extrusion process, the die head is a core component, and its performance directly affects the quality of the film product. After the die head has been used for a period of time, the surface of the extrusion channel will be worn and scaled, so the die head needs to be cleaned and maintained regularly. In order to achieve the diversity and flexibility of extruded products, a complex die head composed of multiple sub-die bodies is generally used, such as a four-petal die head. However, the four-petal die head also puts forward higher requirements for maintenance.

[0003] In order to facilitate the cleaning of the four-petal die head, there is a four-petal die head disassembly and assembly auxiliary device on the market. The patent number is: ZL202010324457.3, and the patent name is: An invention patent for a die head disassembly and assembly auxiliary device and a disassembly method. The patent discloses the following content: The device includes a first frame and two groups of second frames, and two parallel tracks are arranged on the first frame. Two first movable plates are movably arranged on each track. The second frame is provided with a second movable plate on the first frame on which the second frame is slidably installed through the track. The two first movable plates and the two second movable plates are respectively used to clamp the four parts of the four-petal die head, and the first movable plate and the second movable plate move along the track to disassemble the four parts, which is convenient for cleaning the internal structure.

[0004] However, although the device realizes the disassembly of the die head by moving along the track, the fixed moving path and limited moving distance of the track limit the separation distance of the various parts of the die head, resulting in the operator inevitably needing to enter the frame for deep cleaning. The small space inside the frame and limited vision not only increase the labor intensity of the operator, but also pose certain safety hazards. In addition, the installation height of the die head on the extruder is different, so each time the die head is disassembled and assembled, it is necessary to use other lifting equipment. The disassembly and assembly process is relatively cumbersome, increasing maintenance costs and downtime. Summary of the invention

[0029] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] It should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0031] like Figure 1 , 2 As shown in Figure 3, a die disassembly and assembly auxiliary device is provided with a first disassembly and assembly mechanism 1 and a second disassembly and assembly mechanism 2, the first disassembly and assembly mechanism 1 and the second disassembly and assembly mechanism 2 are symmetrically arranged, the first disassembly and assembly mechanism 1 includes a frame 3, the first support unit 4 and the second support unit 5 are respectively arranged on both sides of the frame 3, the first support unit 4 and the second support unit 5 are both provided with a die clamping unit 6, the frame 3 is provided with a translation unit 7, the second support unit 5 is arranged on the translation unit 7, and the first disassembly and assembly mechanism 1 and the second disassembly and assembly mechanism 2 are independently arranged.

[0032] Specifically, the first disassembly and assembly mechanism 1 and the second disassembly and assembly mechanism 2 need to be used at the same time, and the die head clamping unit 6 is used to clamp and lock the die head 9. The two groups of first support units 4 and second support units 5 are provided with die head clamping units 6 to facilitate clamping the four parts of the die head 9. When in use, the four parts of the die head 9 (left half mold, right half mold and respective die lips) are clamped respectively by the die head clamping units 6 on the first disassembly and assembly mechanism 1 and the second disassembly and assembly mechanism 2, and the die head parts (left half mold and right half mold) originally connected together are separated by dragging the first disassembly and assembly mechanism 1 and the second disassembly and assembly mechanism 2. The translation unit 7 drives the second support unit 5 to move horizontally, so that the die lip is further separated from the half mold body, and the die head 9 is completely separated for easy cleaning. In the present application, the first disassembly and assembly mechanism 1 and the second disassembly and assembly mechanism 2 are independently arranged, so that the die head 9 is more fully separated and is not limited by the length of the track. The cleaning and maintenance work can be completed without the need for operators to go deep into the frame, which significantly reduces the difficulty of operation and safety risks; the first disassembly and assembly mechanism 1 and the second disassembly and assembly mechanism 2 have the same structure and can be used interchangeably, which greatly improves the use efficiency of the equipment.

[0033] like Figure 2 As shown, lifting drives 8 are arranged on both sides of the frame 3, and the lifting drives 8 include a first lifting drive 81 and a second lifting drive 82, and the first supporting unit 4 and the second supporting unit 5 are arranged on the first lifting drive 81 and the second lifting drive 82 respectively.

[0034] Specifically, the first lifting drive 81 and the second lifting drive 82 respectively drive the first support unit 4 and the second support unit 5 to move in the vertical direction until the support surface reaches a height matching the die head 9. Through the first lifting drive 81 and the second lifting drive 82, the equipment can adapt to dies 9 of different heights, and the installation and disassembly of the die head 9 can be completed without additional equipment, thereby improving the flexibility of operation.

[0035] like Figure 2 , 3 As shown, the first support unit 4 is provided with a first fixed support frame 41, and a first support lifting plate 42 is provided on the first fixed support frame 41, the first support lifting plate 42 is connected to the first lifting drive 81, and first fixed support vertical plates 43 are slidably provided on both sides of the first support lifting plate 42, and the first fixed support vertical plates 43 are fixedly provided on the first fixed support frame 41.

[0036] Specifically, the first lifting driver 81 can drive the first support lifting plate 42 to slide between the first fixed support vertical plates 43 to achieve vertical ascent or descent. Since the first fixed support vertical plates 43 are fixedly arranged on the first fixed support frame 41, the stability of the first support lifting plate 42 during the lifting process is ensured.

[0037] like Figure 3 As shown, the second support unit 5 is provided with a second support lifting plate 51, the second support lifting plate 51 is connected to the second lifting drive 82, and second fixed support vertical plates 52 are slidably provided on both sides of the second support lifting plate 51, and the second fixed support vertical plates 52 are fixedly provided on the translation unit 7.

[0038] Specifically, the second lifting driver 82 can drive the second supporting lifting plate 51 to slide between the second fixed supporting vertical plates 52 to achieve vertical ascent or descent, and the translation unit 7 can also move horizontally as needed to adjust the overall position of the second supporting unit 5.

[0039] like Figure 2 , 3 As shown, the translation unit 7 includes a translation rail 71 arranged on both sides of the frame 3, a translation slider 72 is arranged on the translation rail 71, a translation connecting plate 73 is arranged between the two translation sliders 72, and the translation unit 7 also includes a translation driver 74 arranged on the frame 3, and the translation driver 74 is connected to the translation connecting plate 73.

[0040] Specifically, the second fixed support upright plate 52 is fixedly arranged on the translation slider 72, and the translation slider 72 is installed on the translation track 71 and can move along the translation track 71. The translation driver can be a motor or a cylinder. In this embodiment, the translation driver 71 is a hand-cranked screw rod, which is sleeved on the translation connecting plate 73. The position of the translation connecting plate 73 is adjusted by rotating the screw rod. When it is necessary to adjust the horizontal position of the second support unit 5 (and the die lip thereon), the screw rod rotates. Due to the sleeve connection relationship between the screw rod and the translation connecting plate 73, the rotating screw rod drives the translation connecting plate 73 to move along the translation track 71, thereby realizing the horizontal position adjustment of the second support unit 5.

[0041] like Figure 3 As shown, the die head clamping unit 6 includes a clamping plate 61 , and a telescopic shaft 62 is provided on the clamping plate 61 . The telescopic shaft 62 is provided on the first supporting unit 4 and the second supporting unit 5 .

[0042] Specifically, the clamping plate 61 is used to directly clamp the die head 9, and the telescopic shaft 62 is installed on the first support unit 4 and the second support unit 5. When the telescopic shaft 62 is extended, the clamping plate 61 is pushed toward the die head 9, thereby clamping the die head 9; when the telescopic shaft 62 is retracted, the clamping plate 61 releases the die head 9.

[0043] like Figure 3As shown, a rotating disk 63 is provided on the telescopic shaft 62 , and a plurality of positioning holes 64 are evenly distributed on the outer edge of the rotating disk 63 . A locking pin 65 is movably provided in the positioning hole 64 , and the locking pin 65 serves to lock the rotating disk 63 .

[0044] Specifically, the angle of the half die head or the die lip can be adjusted by rotating the rotating disk 63, which is convenient for cleaning and maintenance. The rotating disk 63 is locked to the support unit by inserting the locking pin 65 into the positioning hole 64.

[0045] like Figure 2 As shown, the first lifting drive 81 and the second lifting drive 82 are screw lifts, and a synchronous connecting rod 83 is provided between the two first lifting drives 81 and the two second lifting drives 82.

[0046] Specifically, a synchronous connecting rod 83 is provided between the two first lifting drivers 81 and the two second lifting drivers 82 to ensure more stable and precise lifting control of the first lifting drivers 81 and the second lifting drivers 82 .

[0047] like Figure 1 As shown, the frame 3 is provided with universal wheels 31 .

[0048] Specifically, by installing the universal wheels 31 , operators can easily push or pull the frame 3 , which reduces labor intensity.

[0049] The present application discloses a die disassembly and assembly auxiliary device, which is provided with a first disassembly and assembly mechanism 1 and a second disassembly and assembly mechanism 2. The first disassembly and assembly mechanism 1 includes a frame 3, and a first support unit 4 and a second support unit 5 are respectively provided on both sides of the frame 3. The first support unit 4 and the second support unit 5 are both provided with a die clamping unit 6, and the second support unit 5 is provided on a translation unit 7. The first disassembly and assembly mechanism 1 and the second disassembly and assembly mechanism 2 are independently provided. When in use, the four parts of the die 9 (left half-mold, right half-mold and respective die lips) are clamped respectively by the die clamping units 6 on the first disassembly and assembly mechanism 1 and the second disassembly and assembly mechanism 2, and the die parts (left half-mold and right half-mold) originally connected together are separated by dragging the first disassembly and assembly mechanism 1 and the second disassembly and assembly mechanism 2. The translation unit 7 drives the second support unit 5 to move horizontally, so that the die lips are further separated from the half-mold body, and the die 9 is completely separated for easy cleaning. In the present application, the first disassembly and assembly mechanism 1 and the second disassembly and assembly mechanism 2 are independently arranged, so that the die head 9 is more fully separated and is not limited by the length of the track. The cleaning and maintenance work can be completed without the need for operators to go deep into the frame, which significantly reduces the difficulty of operation and safety risks; the first disassembly and assembly mechanism 1 and the second disassembly and assembly mechanism 2 have the same structure and can be used interchangeably, which greatly improves the use efficiency of the equipment.
