DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] See also Figures 1 to 4 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: a film feeding fixture, comprising a mounting plate 1 and a base plate 2 mounted on one side of the mounting plate 1, a feeding seat 3 is fixed to the side of the base plate 2, a rectangular empty slot 31 is opened at the center of the feeding seat 3, a plurality of nozzle mounting slots 33 are opened at the two side edges of the feeding seat 3, and an air duct 32 communicating with the nozzle mounting slot 33 is opened inside the feeding seat 3, the bottom end of the air duct 32 extends all the way to the bottom of the feeding seat 3, a negative pressure nozzle 4 is installed in the nozzle mounting slot 33, and the front end of the negative pressure nozzle 4 extends to the feeding seat 3. On the surface of the material seat 3, the rear end of the negative pressure suction nozzle 4 is fixed with an end 41, and the end 41 penetrates into the airway 32. When used later, the airway 32 on the bottom surface of the feeding seat 3 can be connected to an external negative pressure air source, and then the external negative pressure air source is started, so that the end of the negative pressure suction nozzle 4 generates a negative pressure airflow, and then the film can be placed on the feeding seat 3 and adsorbed and clamped by multiple negative pressure suction nozzles 4. The feeding seat 3 and the film adsorbed and clamped on the feeding seat 3 can be normally driven by external force. The mounting plate 1 is sent into the mold to complete the feeding. A clamping structure 5 is provided between the negative pressure suction nozzle 4 and the feeding seat 3;

[0021] The clamping structure 5 includes two movable grooves 51 opened in the feeding seat 3, and the two movable grooves 51 are respectively located at the top and bottom of the suction nozzle installation groove 33. A spring 52 and a right-angled triangle telescopic clamping block 53 are arranged in the movable groove 51. The surface of the negative pressure suction nozzle 4 is provided with an annular clamping groove 54 corresponding to the right-angled triangle telescopic clamping block 53. The end of the right-angled triangle telescopic clamping block 53 pops out into the annular clamping groove 54, which can stably limit the negative pressure suction nozzle 4 to ensure the installation stability of the negative pressure suction nozzle 4. The clamping structure 5 also includes two side slide grooves 56 opened on the side of the feeding seat 3. A side slide block 57 is slidably arranged in the side slide groove 56. A connecting rod 55 is welded and fixed to one side surface of the side slide block 57. The end of the connecting rod 55 passes through the movable groove 51 and is fixedly connected to the right-angled triangle telescopic clamping block 53. One end of the side slide block 57 extends to the side of the feeding seat 3 and is fixed with a side shift block 58. If the negative pressure suction nozzle 4 is to be removed later, The two side shift blocks 58 only need to be shifted, so that the side slider 57 pulls the right-angled triangle telescopic block 53 into the movable groove 51 through the connecting rod 55, and compresses the spring 52 until the end of the right-angled triangle telescopic block 53 is completely moved out of the annular groove 54, and the limit of the negative pressure suction nozzle 4 can be released. At this time, the negative pressure suction nozzle 4 can be directly pulled out from the suction nozzle mounting groove 33 to achieve the rapid disassembly of the negative pressure suction nozzle 4. When the negative pressure suction nozzle 4 is subsequently installed, it is only necessary to insert the negative pressure suction nozzle 4 into the suction nozzle mounting groove 33, so that the end head 41 penetrates into the airway 32. During the insertion process of the negative pressure suction nozzle 4, the end of the right-angled triangle telescopic block 53 will be gradually squeezed into the movable groove 51, thereby achieving the smooth insertion of the negative pressure suction nozzle 4, until the negative pressure suction nozzle 4 is inserted into place, the end of the right-angled triangle telescopic block 53 will be pushed by the spring 52 to be stuck in the annular groove 54, and the rapid installation of the negative pressure suction nozzle 4 can be completed.

[0022] A rod hole is provided between the side sliding groove 56 and the movable groove 51 , and the rod hole corresponds to the connecting rod 55 , so that the connecting rod 55 can pass through smoothly.

[0023] Among them, the connecting rod 55 passes through the inner side of the spring 52, so that the connecting rod 55 will not affect the normal expansion and contraction of the spring 52. One end of the spring 52 is in close contact with the inner wall of the movable groove 51, and the other end of the spring 52 is fixedly connected to the right-angled triangle expansion block 53 to ensure the installation stability of the spring 52.

[0024] A pop-up hole is provided between the movable groove 51 and the nozzle mounting groove 33 , and the pop-up hole corresponds to the end of the right-angled triangle telescopic block 53 , so that the end of the right-angled triangle telescopic block 53 can be ejected smoothly.

[0025] Example 2

[0026] See also Figures 1 to 5, which is the second embodiment of the utility model, is based on the previous embodiment, but differs in that the overall sealing performance of the negative pressure nozzle 4 after installation can be improved by setting a sealing structure, thereby ensuring the use stability of the entire feeding fixture and the subsequent adsorption stability of the film.

[0027] Specifically, it also includes a sealing structure, which is arranged between the negative pressure suction nozzle 4 and the suction nozzle mounting groove 33. The sealing structure includes a rubber ring 42, an annular sealing protrusion 43 and an annular sealing groove 34. The rubber ring 42 is sleeved on the surface of the end head 41 and is located on the inner side of the suction nozzle mounting groove 33. The rubber ring 42 is pressed between the negative pressure suction nozzle 4 and the inner wall of the suction nozzle mounting groove 33, and an annular seal can be formed after the negative pressure suction nozzle 4 is installed. An integrated annular sealing protrusion 43 is arranged on one side surface of the rubber ring 42. The rubber ring 42 and the annular sealing protrusion 43 are both made of rubber material. An annular sealing groove 34 corresponding to the annular sealing protrusion 43 is opened on the inner wall of the suction nozzle mounting groove 33. The annular sealing protrusion 43 is squeezed into the annular sealing groove 34, which can further improve the sealing performance of the negative pressure suction nozzle 4 after installation, prevent air leakage, and ensure the stability of the subsequent negative pressure suction nozzle 4 when adsorbing film.

[0028] Although the embodiments of the present invention have been shown and described (see the above detailed description for details), it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
