Description

Technical Field

[0001] The utility model relates to the technical field of film packaging equipment, in particular to a film loading mechanism Background Art

[0002] In the prior art, there is a Chinese utility model patent with the patent number "201922022633.3". The patent name is: film loading mechanism, including a film roll carrying assembly for carrying a film roll, a film roll positioning assembly for adjusting the position of the film roll on the film roll carrying assembly, a film conducting assembly for conducting the film and adjusting the direction of the film, and a film loading assembly for completing the loading of the film. However, it uses a sliding method to load the film, which makes it difficult for the upper fork film guide plate to hook the film, and it is easy for the film to fall off during loading, and the sliding loading method is used, which requires a guide structure to prevent the upper fork film guide plate from deviating. Summary of the Invention

[0003] Purpose of the present invention: In order to overcome the defects of the prior art, the present invention provides a film loading mechanism, which adopts a flip insertion method to load the film, has a relatively simple structure, and does not require a guide structure for guidance.

[0004] The utility model discloses a film loading mechanism, comprising a frame, on which a film roller for sleeved film rolls and a reversing roller for film pulling and reversing are rotatably arranged, and is characterized in that it further comprises:

[0005] The film loading channel is provided on the frame for the film to pass through.

[0006] The film loading cover plate is hinged on the frame at two opposite sides and is arranged in a 7-shape as a whole, so that it can be turned over to hook the film on the reversing roller and rotate it to pull it onto the film loading channel.

[0007] By adopting the above technical solution, when in use, the film roll is placed on the film roller, and then the film on the film roll is reversed and pulled by the reversing roller. Further, the film loading cover is rotated to load the film into the film loading channel. The film loading cover adopts a flipping and inserting method to load the film. Its structure is relatively simple, and it does not require a guide structure for guidance. It can also prevent the film loading cover from falling, and is relatively stable when in use.

[0008] The utility model is further configured as follows: it also includes a split front film clamping seat and a rear film clamping seat, the frame is also provided with a driving component for driving the front film clamping seat to move forward and backward relative to the rear film clamping seat, the film loading channel is provided on the front film clamping seat and the rear film clamping seat, and the front film clamping seat and the rear film clamping seat are both provided with clamping parts for clamping or releasing the film.

[0009] By adopting the above technical solution, the film can be clamped by the clamping member of the front film clamping seat, and then the front film clamping seat can be driven to slide by the driving assembly so that the film can be pulled out. Furthermore, the clamping member on the rear film clamping seat will clamp the film in the corresponding film loading channel, which can prevent the film from escaping from the film loading channel when the film is cut and packaged.

[0010] The present invention is further configured as follows: a plurality of saw teeth are arranged at intervals on the bottom of the film loading cover plate, a avoidance groove is formed between two adjacent saw teeth, and the clamping piece located at the front film clamping seat corresponds to the avoidance groove.

[0011] By adopting the above technical solution, the serrations can better hook the film and guide it to the film loading channel, and form an avoidance groove to prevent the clamping parts on the front film clamping seat from being clamped on the film loading cover, so that the film can be clamped on the film loading channel of the front film clamping seat. Furthermore, the front film clamping seat can slide relative to each other to pull the film out for packaging.

[0012] A further configuration of the present invention is that the frame is further provided with a blocking member for limiting the flipping angle of the film loading cover.

[0013] The above technical solution has a positioning effect. When the film loading cover plate rotates at an excessively large angle, it is likely to affect subsequent film processing.

[0014] The utility model is further configured as follows: the blocking member includes a blocking block provided on the frame, the film loading cover is provided with a blocking sheet abutting against the blocking block, and a buffer pad is provided on the blocking sheet or the blocking block for buffering when the two come into contact.

[0015] With the above technical solution, when the film is loaded, the blocking sheet and the blocking block will contact each other and generate an impact force, so a buffer pad is used to buffer the impact, which can prevent hard collisions and thus increase the service life.

[0016] A further configuration of the present invention is that a pull ring is further provided on the rear side of the film loading cover.

[0017] By adopting the above technical solution, it is convenient to pull the film loading cover plate and rotate it to open and rotate it to load the film. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings:

[0026] In the description of the present invention, it should be understood that the terms "upper", "lower", "bottom", "top", "front", "back", "inside", "outside", "left", "right", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0027] The utility model discloses a film loading mechanism, comprising a frame 1, on which a film roller 2 for sleeved film roll 4 and a reversing roller 3 for film pulling and reversing are rotatably provided. In an embodiment of the utility model, the mechanism further comprises:

[0028] The film loading channel 5 is provided on the frame 1 for the film to pass through.

[0029] The film loading cover 6 is hinged on the frame 1 at two opposite sides (which can support the film loading cover 6 to prevent it from falling and enable it to rotate relatively), and the overall arrangement is in a 7 shape so that it can be flipped to hook the film on the reversing roller 3 and rotate and pull it to the film loading channel 5.

[0030] By adopting the above technical solution, when in use, the film roll 4 is placed on the film roller 2, and then the film on the film roll 4 is reversed and pulled by the reversing roller 3. Further, the film loading cover 6 is rotated to load the film onto the film loading channel 5. The film loading cover 6 adopts a flipping and inserting method to load the film. Its structure is relatively simple, and it does not require a guide structure for guidance. It can also prevent the film loading cover 6 from falling, and it is relatively stable when used.

[0031] The film loading channel 5 is provided on the front film clamping seat 71 and the rear film clamping seat 72, and the front film clamping seat 71 and the rear film clamping seat 72 are both provided with a driving assembly 8 for driving the front film clamping seat 71 to move forward and backward relative to the rear film clamping seat 72. The film is opened by the clamping member 9 (the clamping member 9 can be an electromagnet or a push pin, and when the push pin is used, it needs to be used in conjunction with an inflation channel. When the inflation channel is inflated, the push pin pops out to clamp the film, and when it is deflated, the push pin falls back to its position). The film can be clamped by the clamping member 9 of the front film clamping seat 71, and then the front film clamping seat 71 can be driven to slide by the driving component 8 so that the film can be pulled out. Furthermore, the clamping member 9 on the rear film clamping seat 72 clamps the film in the corresponding film loading channel 5, which can prevent the film from completely detaching from the front film clamping seat 71 and the rear film clamping seat 72 when the film is cut and packaged.

[0032] The bottom of the film loading cover 6 is provided with a plurality of serrations 61 at intervals, and an avoidance groove 62 is formed between two adjacent serrations 61. The clamping member 9 located at the front film clamping seat 71 corresponds to the avoidance groove 62. The serrations 61 can better hook the film and guide it to the film loading channel 5, and the avoidance groove 62 is formed to prevent the clamping member 9 on the front film clamping seat 71 from being clamped on the film loading cover 6, so that the film can be clamped on the film loading channel 5 of the front film clamping seat 71. Furthermore, the relative sliding of the front film clamping seat 71 can pull the film out for packaging.

[0033] The frame 1 is also provided with a blocking member 10 for limiting the flipping angle of the film loading cover 6, which has a positioning effect. When the film loading cover 6 rotates at an excessively large angle, it is easy to affect the subsequent film processing.

[0034] The blocking member 10 includes a blocking block provided on the frame 1, and a blocking sheet 20 is provided on the film loading cover 6 to abut against the blocking block, and a buffer pad 30 is provided on the blocking sheet 20 or the blocking block to buffer when the two come into contact. When the film is loaded, the blocking sheet 20 contacts the blocking block and generates an impact force, so a buffer pad 30 is used for buffering, which can prevent hard collisions and thus increase service life.

[0035] A pull ring 40 is further provided on the rear side of the film loading cover 6 , which can be used to pull the film loading cover 6 to rotate it open and rotate it to load the film.
