Description

Technical Field

[0001] This utility model belongs to the field of thin film production technology, specifically relating to a thin film coating and winding mechanism. Background Technology

[0002] Film is a thin, soft, transparent sheet made of plastic, adhesive, rubber, or other materials. After production, it needs to be rolled up according to the sales unit and finally sold in rolls. During the film rolling process, after one roll of film is rolled up, it needs to be cut to replace the core of the next roll. The taut film will loosen when cut, and the film needs to be tightened again and rolled up again when processing the next roll of film, which requires a certain amount of processing time.

[0003] To address this, a film winding device with announcement number "CN221565356U" is disclosed. This device includes a base and a positioning mechanism. The positioning mechanism comprises two side plates symmetrically positioned on the top surface of the base. Each side plate has an open, movable groove. A pressure rod is movably connected to the inside of the movable groove. There are two side plates, one vertically and one vertically, with the same number of pressure rods as the side plates. A rack is provided on the end face of each pressure rod furthest from the other. A gear is meshed with the outside of the rack, and an auxiliary rotating rod is provided inside the gear. The auxiliary rotating rod is connected to the side plate by a bearing. The rack, gear, and auxiliary rotating rod are all located on the outside of the side plates. When a section of film winding is completed and the next section needs to be moved, the pressure rods can clamp the film, keeping the cut film taut. This eliminates the need to re-arrange the film during the next winding stage, saving time when replacing the roll core.

[0004] However, for the aforementioned film processing winding device, although the upper winding drum can be fixed in place, the threaded rod rotates in the connecting groove when the detachable rotating rod rotates, which does not affect the normal operation of the detachable rotating rod. It can fix upper winding drums of different lengths on the detachable rotating rod, so that the upper winding drum will not rotate on its own when the detachable rotating rod drives the upper winding drum to rotate, thereby improving stability. At the same time, the design of this mechanism is flexible and can be freely adjusted according to the conditions of the upper winding drum. However, there are still the following obvious defects in use: Since the detachable rotating rods at both ends of the upper winding drum are inserted into the side plates on both sides, manual disassembly is required when unloading the rolled film. During disassembly, the increased weight of the upper winding drum after film winding makes unloading more difficult and prone to impact with the side plates and falling to the ground, which is unsafe. Manual unloading can easily lead to the film being scratched and damaged. Utility Model Content

[0005] The purpose of this invention is to provide a thin film coating and winding mechanism to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thin film coating and winding mechanism, comprising:

[0007] The upper winding base has an upper winding and unwinding block that is pneumatically lifted and lowered within the side plate of the upper winding fixing frame for winding and unwinding the rolled film and the roll roller. One side of the two side plates of the upper winding fixing frame is provided with a roll blocking block for automatically unwinding the rolled film. The two side plates of the upper winding fixing frame are provided with vertical sliding grooves that limit the lifting and sliding of the upper winding and unwinding block.

[0008] The pusher plate is located on the inner side of the bottom end of the vertical slide groove, and a through groove is provided on one side wall of the bottom end of the vertical slide groove to allow the rolled film to be fed out and the roll roller to be wound up for film winding. The upper end of one side of the upper winding fixing frame is provided with a cutting and pressing mechanism for cutting and pressing the film, and the vertical bottom end of the cutting and pressing mechanism is provided with a supporting cutting table for supporting cutting and pressing the film.

[0009] Preferably, the upper roll fixing frame is fixed to the end of the upper roll base, and the upper end of the inner two side walls of the upper roll fixing frame is provided with a limiting assembly block with an arc groove. The limiting assembly block is perpendicular to the upper roll unloading block, so as to realize the clamping and positioning function in the film rolling of the film roll body and ensure the stability of the film roll.

[0010] Preferably, cylinders A are provided on both sides of the bottom of the upper winding fixing frame, and the piston rod of cylinder A is fixed to the lower end face of the upper winding unloading block. A film rolling roller is horizontally placed at the end of the upper winding unloading block. The shafts at both ends of the film rolling roller are placed in the semi-circular groove of the upper winding unloading block and extend through the vertical slide groove to both sides of the upper winding fixing frame, so as to achieve effective limiting of the upper winding and unloading of the film rolling roller.

[0011] Preferably, a shrinkage groove is provided at the bottom of the inner side of the vertical chute, and the pusher plate is movably disposed inside the shrinkage groove. A cylinder B is installed on the outer side of the upper roll fixing frame through the inner side of the shrinkage groove, and one end of the cylinder B is fixed to one side of the pusher plate, so that the film roll body that has been rolled up inside the chute is pushed to automatically unload the film.

[0012] Preferably, the cutting and pressing mechanism includes a top plate fixed to the upper end of one side of the upper roll fixing frame, and a cylinder C is provided on the lower end of the top plate. A film cutting blade is fixed at the bottom end of the cylinder C. A cylinder D is provided on the same side of the cylinder C and located on the lower end of the top plate. A positioning pressure roller for pressing and cutting the film is provided at the lower end of the cylinder D. The film can be pressed at the end to be cut during feeding, so as to facilitate the film being wound by the upper roll film roller.

[0013] Preferably, the lower end of the support cutting table is provided with strip-shaped support plates fixed to one side of the upper roll fixing frame, and a film support roller is rotatably provided between the inner sides of the strip support plates to achieve the function of pressing and supporting one end of the cut film, thereby improving the tension of the film.

[0014] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This film coating winding mechanism, through a winding fixing frame at the end of the winding base, a winding unloading block slidably mounted within the winding fixing frame via a vertical slide groove, and a fixed connection between the winding unloading block and the piston rod of cylinder A, and with the communication between a through groove on one side of the winding fixing frame and the bottom of the vertical slide groove, and in conjunction with a winding material blocking block, after the end of the completed film winding roller is cut, the retraction of the piston rod by cylinder A causes the winding unloading block to move downward within the winding fixing frame, and the film winding roller... The rotating shafts at both ends of the roll automatically move down to the bottom through slot in the vertical slide. At the same time, the upper winding unloading block continues to move down, so that the film roll body is supported in the through slot by the shafts at both ends. Then, the cylinder B moves the pusher plate forward to push the film roll body through the through slot and slides at an angle. The sliding film roll body is blocked by the winding material blocking plate at both ends of its shafts. This realizes the automatic unloading of the completed film roll body from the upper winding fixing frame, so that the automatic unloading of the film roll body will not cause the problem of bumping, falling and scratching damage, thus ensuring the safety of unloading the rolled film.

[0015] By connecting the through groove on one side of the upper winding fixing frame with the bottom of the vertical slide groove, and by using the upper winding unloading block to lift the unwound film roll body, while the upper winding unloading block and the limiting combination block combine to press the rotating shafts at both ends of the film roll body, when the film roll body needs to be wound up after film winding is completed, the unwound film roll body can be placed between the upper winding fixing frame and the inner side of the upper winding fixing frame using the through groove support, so that the rotating shafts at both ends are supported in the vertical slide groove. Then, the cylinder A pushes the loading block to lift the arc groove of the shaft to the film winding position, so that the upper winding unloading block and the limiting combination block combine to position the film roll body, thereby realizing the automatic winding of the film roll body, thus improving the accuracy of the winding position of the film roll body, and preventing the phenomenon of positional deviation during film winding.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: a thin film coating and winding mechanism, comprising:

[0022] The upper winding base 1 has an upper winding and unwinding block 3 that is pneumatically lifted and lowered within the side plate of the upper winding fixing frame 2. This block is used to roll up and unwind the film and the roll roller. The upper winding base 1 has a vertical limit movement for the upper winding and unwinding of the film roller 11 to keep it stable. The upper winding fixing frame 2 has a roll material blocking block 4 on one side of each of its two side plates to block the automatic unwinding of the film. This block blocks the film roller 11 after it slides out of the upper winding fixing frame 2. The end of the roll material blocking block 4 has a blocking and limiting groove that is inclined and penetrates the pith. The upper winding fixing frame 2 has vertical sliding grooves 5 on its two side plates to limit the lifting and lowering of the upper winding and unwinding block 3. This allows the rotating shafts at both ends of the film roller 11 to extend to the outside of the upper winding fixing frame 2 and be connected to the winding mold transmission mechanism.

[0023] The pusher plate 13 is located on the inner side of the bottom end of the vertical slide 5. It allows the film roll body 11, after the film is wound up, to be pushed out automatically for unloading. A through groove 6 is provided on one side wall of the bottom end of the vertical slide 5 to allow the rolled film to be unloaded and the film roll to be wound up, which facilitates the unloading and unloading of the film roll body 11. A cutting and pressing mechanism 7 is provided on the upper end of one side of the upper winding fixing frame 2 to cut and press the film. It can press the film during cutting to maintain the tension of the film and avoid wrinkles during film winding. The vertical bottom end of the cutting and pressing mechanism 7 is provided with a support cutting table 8 to support the film during cutting and pressing. The film cutting table 8 has a V-shaped cutting groove at its end.

[0024] The upper winding fixing frame 2 is fixed to the end of the upper winding base 1. The upper ends of the two inner side walls of the upper winding fixing frame 2 are provided with limiting blocks 9 with arc grooves. The limiting blocks 9 are perpendicular to the upper winding unloading block 3 and can be used to position the shafts at both ends of the film roll body 11. The two sides of the bottom of the upper winding fixing frame 2 are provided with cylinders A10. The top of the piston rod of the cylinder A10 is fixed to the lower end face of the upper winding unloading block 3, which pushes the film roll body 11 to move up and down to realize automatic winding and unloading. The film roll body 11 is placed horizontally at the end of the upper winding unloading block 3. The shafts at both ends of the film roll body 11 are limited. The film roll 11 is placed in the semi-circular groove of the upper roll unloading block 3 and extends through the vertical slide 5 to both sides of the upper roll fixing frame 2. This facilitates the positioning of the film roll 11 during the upper roll and unloading process. A shrinkage groove 12 is provided at the bottom of the inner side of the vertical slide 5. The pusher plate 13 is movably arranged inside the shrinkage groove 12. A cylinder B14 is installed on the outer side of the upper roll fixing frame 2 through the inner side of the shrinkage groove 12. One end of the cylinder B14 is fixed to one side of the pusher plate 13. This allows the film roll 11 to be automatically pushed and unloaded after the film is wound up. The unloading can be done by manual disassembly and assembly of the clamps by personnel.

[0025] The film cutting and pressing mechanism 7 includes a top plate 15 fixed to the upper end of one side of the upper roll fixing frame 2, and a cylinder C16 is provided on the lower end face of the top plate 15 to push the film cutting blade 17 to move up and down to cut the film. The film cutting blade 17 is fixed at the bottom end of the cylinder C16 to realize automatic cutting of the film. A cylinder D18 is provided on the same side of the cylinder C16 and located on the lower end face of the top plate 15. A positioning roller 19 for pressing and cutting the film is provided at the lower end of the cylinder D18. The downward positioning during film cutting maintains tension. A strip support plate 20 fixed to one side of the upper roll fixing frame 2 is provided on the front and back of the lower end face of the support cutting table 8. A film support roller 21 is rotatably provided between the inner sides of the strip support plate 20 to realize the pressing and positioning of the film after cutting.

[0026] Specifically, in use, the winding mechanism is fixed to one side of the coating machine's output end using the winding base 1, and the strip support plate 20 corresponds to the film output end of the coating machine. The winding mechanism is connected to the bottom of the vertical slide 5 via a through groove 6 on one side of the winding fixing frame 2. The cylinder A10 uses the winding unloading block 3 to lift the unwound film roller 11. Simultaneously, the winding unloading block 3 and the limiting assembly block 9 press the rotating shafts at both ends of the film roller 11 together, allowing the film to be wound up. When unwinding requires film winding, the unwound film roller 11 can be supported by the through groove 6 and placed inside the upper winding fixing frame 2, so that the rotating shafts at both ends are supported in the vertical slide groove 5. Then, the cylinder A10 pushes the upper winding unloading block 3 so that its arc groove positions the shaft and lifts it to the film winding position. The upper winding unloading block 3 and the limiting combination block 9 combine to position the film roller 11, thereby realizing the automatic winding of the film roller 11. After the film winding is completed... After the end of the roll body 11 is cut, the positioning pressure roller 19 is pushed down by the cylinder D18 to combine with the film support roller 21 to press the film and maintain tension. At the same time, the film cutting blade 17 is pushed down by the cylinder C16 to cut the film. After the film is cut, the upper roll unloading block 3 moves down in the upper roll fixing frame 2 by the contraction of the piston rod by the cylinder A10. The rotating shafts at both ends of the roll body 11 automatically move down to the position of the bottom through groove 6 in the vertical slide groove 5. At the same time, the upper roll unloading block 3 continues to move down. The film roll body 11 continues to move downward, supported by the shafts at both ends in the through groove 6. Then, the pusher plate 13 is moved forward by the cylinder B14 to push the film roll body 11 through the through groove 6 and slide at an angle. The sliding film roll body 11 is blocked by the roll material blocking block 4, so that the film roll body 11 can be automatically unloaded and separated from the upper roll fixing frame 2 after the film is rolled. This ensures that the automatic unloading of the film roll body 11 will not cause the problem of bumping, falling and scratching, thus ensuring the safety of unloading the rolled film.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
