In the technical scheme shown in the drawing, a longitudinal moving pair 2 and a first transverse moving pair 3 arranged on the longitudinal moving pair 2 are arranged on a machine frame 1. The moving supporting plate 30 is arranged on the first transverse moving pair 3, can move transversely based on the first transverse moving pair 3, and can move vertically based on the longitudinal moving pair 2. In the specific embodiment shown in fig. 2 and 3, the longitudinal moving pair 2 comprises a lifting frame 21 arranged on the machine frame 1 in a longitudinal sliding manner, a lifting rack 22 arranged on the lifting frame 21, and a longitudinal driving motor 23 fixed on the machine frame 1, wherein the output end of the longitudinal driving motor 23 is meshed with the lifting rack 22 by adopting a gear; when the longitudinal driving motor 23 rotates, the lifting rack 22 and the lifting frame 21 connected with the lifting rack are driven to move up and down. The first transverse moving pair 3 comprises a transverse moving plate 31 arranged on the lifting frame 21 in a sliding mode and a transverse driving motor 33 fixed on the lifting frame 21; the transverse moving plate 31 is provided with a transverse rack 32 arranged along the length direction of the transverse moving plate, and the output end of a transverse driving motor 33 is meshed with the transverse rack 32 by adopting a gear; the traverse motor 33 drives the gear to rotate, thereby moving the engaged traverse rack 32 and the connected traverse plate 31.

In this embodiment, the motion plate 30 is connected to and fixed on the lateral moving plate 31 of the first lateral moving pair 3 or is constructed by a part of the lateral moving plate 31. The upper end surface of the moving pallet 30 is recessed from the lateral moving plate 31 to form a hole plate positioning groove 301, and a plurality of positioning blocks 302 are arranged on the edge of the hole plate positioning groove 301. During installation, the orifice plate is embedded in the orifice plate positioning groove 301, and positioning is realized through a plurality of positioning blocks 302 on the edge of the orifice plate positioning groove.

As shown in fig. 4, a material anti-dropping claw block 5 is arranged on the lateral moving plate 31 beside the moving pallet 30, and a hook 51a for clamping the orifice plate is movably arranged in the material anti-dropping claw block 5. In the moving path of the traverse plate 31, the hook 51a releases the restriction of the orifice plate at the loading/unloading station. The moving support plate 30 in this scheme is used for installing and positioning the orifice plate, and is located on the transverse moving plate 31 or is a part of the transverse moving plate 31, that is, the moving plate 31 moves transversely, so that the station movement of the orifice plate is realized, and the film tearing or sealing is performed in a matching manner. On the basis, the scheme is that the material anti-falling claw block 5 is arranged on the transverse moving plate 31 beside the moving supporting plate 30, and the material anti-falling claw block 5 adopts the clamping hook 51a to be capable of clamping the positioning pore plate, so that the positioning pore plate is firmly positioned in the machining process, and the dislocation or falling-off condition is avoided.

And, pothook 51a in this scheme can remove the restriction to the orifice plate on material loading and unloading station, and at the in-process of carrying out orifice plate material loading and unloading, because pothook 51 a's restriction has already been removed to can not interfere to the orifice plate material loading and unloading, and then removed hasp and unblock operation, promote work efficiency.

In a specific embodiment, the hook 51a in the material anti-falling claw block 5 is slidably disposed on the lateral moving plate 31, and the hook 51a can slide relative to the lateral moving plate 31 in the moving direction of the lateral moving plate 31. When the movable pallet 30 moves to the loading and unloading station, the hook 51a slides relative to the transverse moving plate 31 to withdraw from the movable pallet 30. In this scheme, the hooks 51a in the material anti-falling claw block 5 realize the adjustment of the hooks 51a relative to the moving pallet 30 based on the relative sliding between the hooks and the lateral moving plate 31 on the basis of the transfer of the lateral moving plate 31, and further realize the release of the limitation on the orifice plate in the loading and unloading station. As shown in fig. 3 and 4, a positioning support plate 52 is slidably disposed on the lateral moving plate 31 along the moving direction thereof, and at least two positioning posts 53 located in the material anti-falling claw block 5 are disposed on the positioning support plate 52. The material anti-drop claw block 5 is internally provided with a positioning strip 51, the positioning strip 51 is positioned between two positioning columns 53, and at least one end part of the positioning strip 51 extends out of the material anti-drop claw block 5 to form the hook 51a. The positioning support plate 52 in this solution is disposed on the lateral moving plate 31, and the lateral moving plate 31 can drive the positioning support plate 52 to move. Meanwhile, the positioning pallet 52 is slidably engaged with the traverse plate 31, and in the moving path of the traverse plate 31, the positioning pallet 52 moves relative to the traverse plate 31 first, and then moves in synchronization with the traverse plate 31.

Based on the above structure, during the moving process of the lateral moving plate 31, the two positioning columns 53 on the positioning support plate 52 and the moving support plate 30 generate relative displacement, and at the same time, the positioning strip 51 is located between the two positioning columns 53, and the two positioning columns 53 push the positioning strip 51, so that the hooks 51a at the end portions of the positioning strip 51 can extend out of the buckling hole plate or retreat to release the buckling relation.

The positioning support plate 52 is positioned below the transverse moving plate 31, and a strip-shaped through hole 521 arranged along the moving direction of the transverse moving plate 31 above the front end part of the positioning support plate 52 is arranged on the transverse moving plate 31. The two positioning columns 53 penetrate through the strip-shaped through hole 521 at the front side and extend into the material anti-falling claw block 5. In this embodiment, two positioning posts 53 pass through the strip-shaped through hole 521. At the beginning of the movement of the lateral moving plate 31, the positioning posts 53 move in the through holes 521 until the positioning posts 53 abut against the inner walls of the through holes 521, and the lateral moving plate 31 does not move synchronously with the positioning pallet 52. Moreover, rolling parts 54 are sleeved on the two positioning columns 53 in the strip-shaped through hole 521, and the rolling parts 54 can reduce the friction resistance between the transverse moving plate 31 and the two positioning columns 53. In addition, in order to prevent the front end portion of the positioning plate 52 from coming off the strip-shaped through hole 521, a plate may be provided below the positioning plate 52.

In a further embodiment, the lateral moving plate 31 above the rear end of the positioning support plate 52 is also provided with a strip-shaped through hole 521 along the moving direction thereof, the rear end of the positioning support plate 52 is provided with a post passing through the strip-shaped through hole 521 at the rear side, and the upper end thereof is provided with a rolling member 54. The rear end of the positioning blade 52 is suspended from the lateral moving plate 31 by a rolling member 54. With the above structure, the positioning of the positioning pallet 52 and the lateral moving plate 31 is achieved.

As shown in fig. 1 and 5, a second transverse moving pair 6 is further disposed on the frame 1 above the moving pallet 30, a bracket 61 is mounted on the second transverse moving pair 6, and the film clamping device 4 and the detecting member are mounted on the bracket 61. The second traverse pair 6 is the same in structure as the first traverse pair 3, and will not be described in detail here. But the second transverse moving pair 6 is perpendicular to the moving direction of the first transverse moving pair 3, so that the moving supporting plate 30 and the film clamping device 4 can move transversely along the frame 1 and the transverse moving directions of the two are perpendicular. According to the scheme, the detection part 62 is used for detecting the height of the pore plate, and the moving supporting plate 30 and/or the film clamping device 4 adjust the longitudinal moving distance based on a detection signal of the detection part 62, so that the film end angle of the pore plate can extend into the clamping end of the film clamping device 4.

The motion layer board 30 in the above-mentioned scheme is used for installing the orifice plate (the background art is called the kit), and film clamping device 4 is used for centre gripping the film end angle on the orifice plate, and after film clamping device 4 gripped the film end angle, motion layer board 30 and film clamping device 4 monarch transverse motion relatively frame 1, because the moving direction of both is mutually perpendicular, so the film can be torn from one side end angle gradually, accomplishes the dyestripping process. And, because the orifice plate specification is different to lead to the orifice plate height difference, this scheme is in order to be applicable to the dyestripping of not co-altitude orifice plate. At least one of the moving blade 30 and the film sandwiching means 4 is provided so as to be movable up and down, and a detecting member 62 is employed for detecting the height of the orifice plate. Based on the detection of the detection part 62, the moving supporting plate 30 is controlled to move upwards and/or the film clamping device 4 moves downwards, so that the film end corner of the orifice plate can extend into the clamping end of the film clamping device 4.

In a specific embodiment, the detecting member 62 is a travel switch disposed on the bracket 61. When the film clamping device 4 moves above the moving supporting plate 30, the longitudinal moving pair 2 drives the moving supporting plate 30 and the pore plate on the moving supporting plate to move upwards until the travel switch is triggered to acquire the height data of the pore plate. In the technical scheme, the second transverse moving pair 6 drives the film clamping device 4 to transversely move. The detection component 62 is a travel switch, and the orifice plate on the moving pallet 30 moves upwards under the driving of the longitudinal moving pair 2, so that the travel switch can be directly or indirectly triggered, and the height of the orifice plate can be further known. In the solution shown in the figure, the orifice plate indirectly triggers the travel switch, i.e. the orifice plate first abuts against the movable clamping block of the film clamping device 4, and the travel switch can be triggered by the longitudinal movement of the movable clamping block.

Further as shown in fig. 7, the film clamping device 4 includes two clamping blocks disposed opposite to each other in the up-down direction, and at least one of the clamping blocks is movably disposed so that the two clamping blocks can move closer to or away from each other. The clamping surfaces of the two clamping blocks are provided with concave-convex textures which are matched with each other. This press from both sides membrane device 4 adopts two grip blocks that set up in opposite directions to press from both sides and gets film end angle, and the activity of at least one grip block sets up in its scheme, makes two grip blocks can be close to relatively or keep away from, can realize getting or unclamping. And, all be equipped with the unsmooth texture of mutual adaptation on the clamping face of two grip blocks in this scheme for stabilize centre gripping film end angle, avoid the film to deviate from two grip blocks.

The film clamping device 4 adopting the scheme is more suitable for clamping the film end corner on the edge of the pore plate, and the film is torn from the film end corner, so that the film has the advantages of small tearing force, stable tearing process and difficulty in tearing.

In the specific scheme, the lower clamping block is a fixed clamping block 41, and the upper clamping block is a movable clamping block 42. The movable clamp block 42 is connected to the output end of the clamp driving part 43, and the clamp driving part 43 drives the movable clamp block 42 to approach or separate from the fixed clamp block 41. The clamp driving member 43 here is an electromagnet that can move axially by an air cylinder, an oil cylinder, or an output shaft. In this embodiment, the fixed holding block 41 and the movable holding block 42 are used, and only the movable holding block 42 is driven by the holding drive member 43 to move, thereby realizing the film holding operation. Compared with the scheme that the two clamping blocks move, the scheme is simple in structure, low in cost and easy to control.

Further, the fixed holding block 41 is connected to a rotating shaft 44, the rotating shaft 44 passes through the upper movable holding block 42, and the upper end of the rotating shaft 44 is connected to the output end of the stripping driving part 45. The fixed clamping block 41 is connected with a demoulding shifting rod 46, the support 61 beside the fixed clamping block 41 is also provided with a fixed shifting rod 47, one end of the fixed shifting rod 47 is fixedly arranged, and the other end of the fixed shifting rod 47 is wound on the clamping block below.
