Description

Technical Field

[0001] This utility model relates to the field of film cutting technology, and more specifically, to a film cutting device. Background Technology

[0002] Industrial X-ray film is short for "industrial X-ray film". Industrial X-ray film is widely used for non-destructive X-ray inspection of components, profiles, parts or welds made of ferrous and non-ferrous metals. Before use, industrial film usually needs to be cut to a specified size by a cutting device.

[0003] For example, patent CN217318234U discloses an automated industrial film cutting device, including a base, a support plate fixedly connected to the top of the base, a drive box fixedly connected to the top of one side of the support plate, and a fixing box located directly below the drive box fixedly connected to the top of the base. The fixing box contains a fixing assembly for fixing industrial films. Although this cutting device has the advantages of simple structure and easy operation, in actual use, because the L-shaped fixing plates are fixedly connected to the upper surface of the lifting plate, the distance between the L-shaped fixing plates is fixed and cannot be adjusted. This results in the L-shaped fixing plates only being able to fix industrial films of fixed length and width, leading to poor applicability and requiring improvement. Utility Model Content

[0027] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0028] The following is in conjunction with the appendix Figures 1-6 This embodiment will be described in further detail.

[0029] Please see Figures 1-4 A film cutting device in this embodiment includes a base plate 100, a connecting plate 110 on the top of the base plate 100, a support plate 111 on one side of the connecting plate 110, a movable cutting component on the support plate 111, a fixing box 120 on the upper surface of the base plate 100 and below the support plate 111, a fixing cavity 300 with an upper opening inside the fixing box 120, a support plate 200 with an upper opening and located in the middle of the fixing cavity 300, a lifting plate 130 that can be raised and lowered inside the fixing cavity 300, a movable fixing frame 210 opposite to the lifting plate 130, and a movable fixing claw 410 for fixing the film 140 inside the fixing frame 210.

[0030] In this embodiment, when cutting the film 140, the film 140 is placed on the support plate 200. At this time, the fixing claws 410 are brought close to each other and located above both sides of the film 140. The lifting plate 130 is moved down to drive the fixing claws 410 to move down and fix both ends of the film 140 to fix the film 140. The film 140 is then cut by starting the cutting assembly.

[0031] In order to prevent the cutting component from damaging the support plate 200, the upper side of the support plate 200 is recessed to form a cutting groove 201. When the cutting component is cutting, it will extend into the cutting groove 201. In order to support the base plate 100, the lower end surface of the base plate 100 and the four corners are provided with support legs 101, which can support the base plate 100.

[0032] Specifically, the support plate 111 has a sliding groove 116 along its width direction. The cutting assembly includes a T-shaped block 113 slidably disposed within the sliding groove 116. Support blocks 112 are provided opposite to each other at both ends of the sliding groove 116. A rotatable lead screw 114 is provided between the support blocks 112. The lead screw 114 is threaded through the T-shaped block 113. A first motor 115 for driving the lead screw 114 to rotate is provided on one side of the support block 112. A rotatable cutting blade 117 is provided on the lower side of the T-shaped block 113 via a second motor 118. 114 is rotatably mounted between support blocks 112 via bearings. The lead screw 114 is threaded through the T-block 113, and the lower end of the T-block 113 passes through the sliding groove 116. Thus, the T-block 113 is restricted by the sliding groove 116 when it moves. That is, the first motor 115 is started to drive the lead screw 114 to rotate, so that the T-block 113 moves along the axial direction of the lead screw 114, so that the cutting blade 117 can move along the cutting groove 201. At this time, the second motor 118 drives the cutting blade 117 to rotate, that is, to cut the film 140.

[0033] Specifically, in order to enable the cutting blade 117 to rotate and cut the film 140, in this embodiment, the lower side of the cutting blade 117 mounted on the T-block 113 extends into the cutting groove 201. Before cutting the film 140, the cutting blade 117 moves to the end of the cutting groove 201. At this time, the film 140 is placed on the support plate 200, and the cutting blade 117 can be cut. The movable arrangement of the fixing frame 210 and the fixing claw 410 allows for the fixing of films 140 of different lengths by moving the fixing frames 210 on both sides of the support plate 200 closer to or further away from the support plate 200. Moving the fixing claw 410 allows for the fixing of films 140 of different widths on the support plate 200. Compared with existing methods, this embodiment can fix films 140 of different lengths and widths, offering better applicability.

[0034] Combination Figure 3 As shown, in this embodiment, the side wall of the lifting plate 130 is slidably attached to the inner wall of the fixed cavity 300, and the fixed cavity 300 is provided with an electric push rod 310 for pushing the lifting plate 130 up and down.

[0035] In this embodiment, the electric push rod 310 enables the lifting plate 130 to rise and fall within the fixed cavity 300, and the side wall of the lifting plate 130 is in contact with the inner wall of the fixed cavity 300, so that the lifting plate 130 can rise and fall relatively stably within the fixed cavity 300 and is less prone to tilting.

[0036] Combination Figure 3 As shown, in this embodiment, the lifting plate 130 is provided with T-shaped grooves 340 along its length direction, the fixing frame 210 is provided with T-shaped sliders 430 that slide within the corresponding T-shaped grooves 340, the lifting plate 130 is provided with a plurality of fixing holes 131 along its length direction, the fixing frame 210 is provided with an extension plate 440 on the side away from the support plate 200, and the extension plate 440 is provided with hand-tightening screws 441 that can be inserted into the corresponding fixing holes 131.

[0037] In this embodiment, when it is necessary to adjust the position of the fixing frame 210 on the lifting plate 130, the lower end of the hand screw 441 can be extended from the corresponding fixing hole 131 by rotating the hand screw 441. At this time, the fixing frame 210 can be moved. When it is moved to the desired position, the hand screw 441 can be rotated again to extend into the fixing hole 131 at the corresponding position, so that the fixing frame 210 can be fixed so that the fixing frame 210 can adapt to films 140 of different lengths.

[0038] The T-shaped slide 340 and T-shaped slider 430 restrict the movement of the fixed frame 210, allowing it to move only along the extension direction of the T-shaped slide 340, thus better enabling the fixed frame 210 to be moved and installed on the lifting plate 130.

[0039] Combination Figure 4-6 As shown, in this embodiment, the fixed frame 210 is provided with a movable cavity 400, one end of the fixed claw 410 extends out of the movable cavity 400, and the movable cavity 400 is provided with a rotatable rotating shaft 420. The rotating shaft 420 is threaded through the fixed claw 410, and the rotation of the rotating shaft 420 is used to drive the fixed claw 410 to move relative to each other.

[0040] In this embodiment, the two ends of the rotating shaft 420 are rotatably mounted in the fixed cavity 300 by bearings. When the rotating shaft 420 rotates, the fixed claw 410 is restricted by the moving cavity 400, so that the fixed claw 410 will move along the axial direction of the rotating shaft 420. The fixed claws 410 approach each other to fix the film 140.

[0041] In order to enable the rotating shaft 420 to rotate and drive the fixed claw 410 to move relative to each other, in this embodiment, the rotating shaft 420 is provided with symmetrical and opposite threads, which respectively engage with the corresponding fixed claw 410 threads, thereby enabling the rotating shaft 420 to rotate and drive the fixed claw 410 to move relative to each other.

[0042] In order to facilitate the rotation of the rotating shaft 420, a third motor 211 for driving the rotating shaft 420 to rotate is provided at one end of the fixed frame 210.

[0043] Combination Figure 1-5 As shown, in this embodiment, a closable door 121 is provided on one side of the fixed cavity 300. One side of the door 121 is hinged to the fixed box 120. An elastic clip 330 is provided opposite to the side of the door 121 near the fixed cavity 300. A detachable brush 331 is provided between the elastic clips 330.

[0044] In this embodiment, one side of the box door 121 is hinged to one side wall of the fixed box 120 by a hinge, and the other side is detachably connected to one side wall of the fixed box 120 by bolts, thereby enabling the box door 121 to be opened and closed. When cleaning the debris on the lifting plate 130 after the film 140 is cut, the box door 121 can be opened and the brush 331 can be taken out to brush the debris on the lifting plate 130 and the debris in the T-shaped slide 340, so that the debris can enter the fixed box 120 for the film 140 cutting operation to be carried out again.

[0045] It should be noted that a side door is provided on the side of the fixing box 120 to facilitate the cleaning of debris inside the fixing box 120.

[0046] In order to facilitate the rotation of the box door 121, a handle 320 is provided on the side of the box door 121 away from the fixed cavity 300.

[0047] Combination Figure 4 As shown, in this embodiment, the fixing claw 410 has an elastic pad at one end face near the film 140.

[0048] In this embodiment, the elastic pad allows the fixing claw 410 to contact the film 140 more gently, thereby reducing damage to the film 140.

[0049] In actual use, when the film 140 needs to be cut, the film 140 is first placed on the support plate 200, and the hand screw 441 is turned so that the hand screw 441 extends out of the fixing hole 131. At this time, the fixing frame 210 is moved. When it is moved to the desired position, the hand screw 441 is turned so that it extends into the fixing hole 131 to fix the fixing frame 210. Then, the third motor 211 is started so that the fixing claws 410 move closer to each other along the rotating shaft 420 to fix the film 140. Then, the electric push rod 310 is started to drive the lifting plate 130 to descend and press the film 140 onto the support plate 200. The first motor 115 is started to drive the cutting blade 117 to rotate and cut the film 140.

[0050] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
