[0003] In the prior art, when film products are packaged into rolls, it is necessary to frequently change rolls. Before the film bag is rolled up, the head of the film bag needs to be guided and attached to the reel manually or by manual bonding. As the reel rotates, the film tape is wound around the reel for at least one circle to ensure that the reel can continue to roll the film bag.
[0004] However, there is a great risk in manually assisting the film bag to be attached to the rotating reel, and the head of the film bag is not easy to be wound onto the winding roller.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0021] like Figure 1 As shown, the present invention provides a winding device for processing thin environmentally friendly bags, comprising: A side plate 10 is installed, and two side plates are arranged opposite to each other. A winding roller 11 is connected to the shaft of the side plate 10, and the winding roller 11 is driven by a power motor to wind the film bag; A guide roller 20 is provided between the mounting side plates 10 and is parallel to the axis of the winding roller 11. The guide roller 20 is located above the winding roller 11 and can be driven by the winding roller 11 to rotate. The guide roller 20 can press the end of the film bag onto the roller surface of the winding roller 11 so that the end of the film bag can rotate and wind around the roller surface of the winding roller 11 for one circle. Among them, a telescopic rod 12 that can extend toward the guide roller 20 is provided on the mounting side plate 10, and the axes of the telescopic rod 12 and the guide roller 20 are perpendicular to each other. An annular connecting ring sleeve 13 is fixed to the movable end of the telescopic rod 12, and a bearing is provided inside the connecting ring sleeve 13 to connect the two ends of the guide roller 20, so the telescopic rod 12 is connected to the top of the connecting ring sleeve 13, so the extended line of the axis of the telescopic rod 12 passes through the center of the circle of the connecting ring sleeve 13; the fixed end of the telescopic rod 12 is hinged to the mounting side plate 10, and the guide roller 20 rotates together with the roller surface of the winding roller 11 as it rotates.
[0022] During the production process of film bags, the device provided by the present invention utilizes the guide roller 20 to fit the head of the semi-finished film bag produced during the production process onto the winding roller 11 by means of roller extrusion and guided transmission. As the winding roller 11 rotates, the film bag is wound around the winding roller 11 for at least one circle to ensure that the winding roller 11 can continuously roll up the film bag.
[0023] In this embodiment, the telescopic rod 12 is freely retractable, and can be extended by the gravity of the guide roller 20 itself, or retracted by the thrust generated by the thickening of the film bag on the winding roller 11 on the guide roller 20, so that the guide roller 20 can continuously limit the overall winding process of the film bag after assisting the film bag head to avoid wrinkles in the rolled film bag. Among them, the telescopic rod 12 matched with the guide roller 20 and the mounting side plate 10 are hinged. When the guide roller 20 is driven by the winding roller 11, it is affected by the friction force and causes the telescopic rod 12 to first swing away from the vertical direction, and gradually extends under the influence of the deadweight of the guide roller 20 during the swinging process. When the telescopic rod 12 reaches the maximum extension, it is preferably in a state that the telescopic rod 12 deviates from the vertical position of the initial state by 30°. This deflection angle is not fixed, so as to ensure that the position of the guide roller 20 will not interfere with the transmission of the surrounding film bags when the telescopic rod 12 is at the maximum extension after swinging.
[0024] In the above embodiment, since the telescopic rod 12 is freely retractable, after the film bag can be stably wound, even if the telescopic rod 12 can enable the guide roller 20 to continuously rotate in conjunction with the winding roller 11 in the extended state, the existence of the guide roller 20 forms a certain resistance to the winding of the film bag, which is not conducive to the improvement of the winding speed.
[0025] To solve the above problems, please continue to refer to Figure 3As shown, in a preferred embodiment provided by the present invention based on the above-mentioned embodiment, an inwardly extending mounting support plate 14 is provided on the mounting side plate 10, an actuating cylinder 15 is provided on the mounting support plate 14, and a lifting block 16 is provided at the free end of the actuating cylinder 15; wherein, the end of the telescopic rod 12 is hinged on the lifting block 16 to control the lifting and lowering of the guide roller 20 through the action of the actuating cylinder 15; when the actuating cylinder 15 is in a retracted state, the actuating cylinder 15 drives the guide roller 20 to rise, the guide roller 20 and the winding roller 11 are separated, and the telescopic rod 12 is in a fully extended state to leave an avoidance space for the film bag to be rolled up under the guide roller 20; when the actuating cylinder 15 is in an extended state, the actuating cylinder 15 drives the guide roller 20 to descend, the guide roller 20 and the winding roller 11 are close to each other, and the telescopic rod 12 is in a partially retracted state, so that the guide roller 20 presses the head of the film bag on the winding roller 11 and continues to move with the rotation of the winding roller 11.
[0026] In this embodiment, the stroke of the actuating cylinder 15 is at least greater than the sum of the maximum extension of the telescopic rod 12 and the maximum thickness of the stacked film bag on the winding roller 11. After the guide roller 20 guides the film bag to roll at least one circle, the film bag can be stably wound on the winding roller 11. The actuating cylinder 15 actively rises to completely lift the guide roller 20 to separate it from the winding roller 11, waiting for the next roll change to repeat the action, thereby avoiding contact between the guide roller 20 and the film bag, which is beneficial to increasing the winding speed of the winding roller 11.
[0027] In order to enable the telescopic rod 12 to automatically return to the vertical initial state after the winding roller 11 stops rotating, as shown in FIG. Figure 7-9 , Fig.11 As shown, in a preferred embodiment provided by the present invention based on the above-mentioned embodiment, a tension spring 17 is obliquely arranged between the telescopic rod 12 and the lifting block 16, and the tension spring 17 is stretched as the telescopic rod 12 swings; wherein, the tension spring 17 is arranged on one side of the telescopic rod 12, and the tension spring 17 can be stretched toward one side of the film bag transmission direction. When the winding roller 11 stops, the tension spring 17 contracts to reset the telescopic rod 12.
[0028] In this embodiment, the tension spring 17 is obliquely arranged between the telescopic rod 12 and the mounting support plate 14, which can not only increase the pressure of the guide roller 20 when pressing the film bag through its own deformation tension, so as to avoid the guide roller 20 from exerting insufficient pressure on the film bag, causing the guide roller 20 to separate from the winding roller 11, but also the setting of the tension spring 17 can automatically reset the telescopic rod 12 to its vertical initial state after the winding roller 11 stops rotating, so that the telescopic rod 12 always remains in a vertical state during the process of being lifted by the actuating cylinder 15.
[0029] In the above embodiment, after the film bag head passes under the winding roller 11 , it cannot be automatically wound up from the side of the winding roller 11 .
[0030] In order to solve the above problems, Figure 1 , 7 As shown, in a preferred embodiment provided by the present invention based on the above-mentioned embodiment, an auxiliary roller 30 is connected to the shaft on the mounting side plate 10, and the auxiliary roller 30 and the winding roller 11 are located at the same horizontal height and are arranged parallel to each other; wherein, the auxiliary roller 30 is arranged close to one side of the winding roller 11, the winding roller 11 rotates counterclockwise, and the auxiliary roller 30 rotates clockwise, and the auxiliary roller 30 can roll the end of the guide film bag upward; a slide groove 18 is provided on the mounting side plate 10, and a slider 19 is provided in the slide groove 18, and both ends of the auxiliary roller 30 are slidably connected in the slide groove 18 through the slider 19, and the auxiliary roller 30 gradually slides away as the stacking height of the film bag on the winding roller 11 increases.
[0031] In this embodiment, by providing the auxiliary roller 30, the head of the film bag can be sandwiched between the winding roller 11 and the auxiliary roller 30 during the conveying process, and then it is easy to be wound above the winding roller 11 for further winding. When the thickness of the film bag folded by the winding roller 11 gradually increases, the folded film bag roll will generate a thrust on the guide roller 20, so that the auxiliary roller 30 slides outward along the slide groove 18 to provide space for the folding of the film bag.
[0032] In the above embodiment, after the auxiliary roller 30 slides outward along the slide groove 18 , it cannot automatically return to the initial position close to the winding roller 11 .
[0033] In order to solve the above problems, Figure 4-6 As shown, in a preferred embodiment provided by the present invention based on the above-mentioned embodiment, the slide groove 18 gradually tilts from a position close to the winding roller 11 to form a slope that can guide the slider 19, and the slope has a highest point and a lowest point in the gravity direction. The auxiliary roller 30 can slide to the highest point of the slide groove 18 and separate from the winding roller 11 by relying on the squeezing thrust force generated by the increase in diameter during the winding of the film bag into a tube, so as to form an escape space for the winding of the film bag; wherein, when the auxiliary roller 30 is located at the lowest point of the slide groove 18, the auxiliary roller 30 is tangent to the roller surface of the winding roller 11, and the central axes of the auxiliary roller 30 and the winding roller 11 are at the same horizontal height; when the auxiliary roller 30 is located at the highest point of the slide groove 18, the auxiliary roller 30 is separated from the winding roller 11, and the horizontal height of the central axis of the auxiliary roller 30 is higher than the horizontal height of the central axis of the winding roller 11.
[0034] In this embodiment, the inclination angle of the middle surface of the slide groove 18 relative to the horizontal plane is preferably within 5° to avoid excessive inclination angle causing the auxiliary roller 30 to be pushed upward with excessive force and thus affecting the winding and stacking of the film bag.
[0035] In another embodiment of the invention, an elastic member 181 fixed to the slider 19 is provided in the slide 18, and the auxiliary roller 30 relies on the elastic force of the elastic member 181 to maintain a state of abutting against the winding roller 11, and the central axes of the auxiliary roller 30 and the winding roller 11 are located at the same horizontal height; wherein, when the auxiliary roller 30 is located at the lowest point of the slide 18, the elastic member 181 is in a partially contracted state, and the thrust of the elastic member 181 toward the winding roller 11 keeps the auxiliary roller 30 and the winding roller 11 in a state where the roller surfaces are tangent; when the auxiliary roller 30 is located at the highest point of the slide 18, the elastic member 181 is in a fully contracted state, and the auxiliary roller 30 is separated from the winding roller 11.
[0036] In this embodiment, the elastic member 181 can adopt a gas spring with stable elastic potential energy change, so that the elastic force on the winding roller 11 is constant when the thickness of the film bag stacking increases, avoiding the squeezing of the auxiliary roller 30 to hinder the winding of the film bag stacking.
[0037] In the above embodiment, when the end of the film bag is transported upward between the winding roller 11 and the auxiliary roller 30, it is easy to lift up and separate from the winding roller 11 during the continuous rotation of the winding roller 11, affecting the winding operation of the end of the film bag.
[0038] In order to solve the above problem, as shown in the figure, in a preferred embodiment provided by the present invention based on the above embodiment, a guide wind knife 40 is provided above the auxiliary roller 30, and the guide wind knife 40 makes the film bag close to the winding roller 11 by blowing out an oblique airflow.
[0039] In this embodiment, by setting the guide wind knife 40, it is possible to blow air tangentially to the winding roller 11, so that the film bag is tightly attached to the winding roller 11 during the winding process and is transported accordingly, thereby ensuring the stability of the film bag end during the winding process; wherein, the guide wind knife 40 is rotatably connected to the mounting side plate 10, and the air outlet of the guide wind knife 40 is along the tangential direction of the winding roller 11.
[0040] In order to increase the tension of the film bag during the transmission process, as shown in the figure, a tensioning roller 50 is provided on one side of the winding roller 11 and is located obliquely above it. The film bag is tensioned and transmitted between the winding roller 11 and the tensioning roller 50. The tensioning roller 50 is axially connected to the mounting side plate 10 and is driven by a power motor.
[0041] In the above embodiment, since the roller surface of the guide roller 20 is usually a rubber roller, it is easy to produce adhesion between it and the film bag, resulting in the guide roller 20 easily sticking to the end of the film bag during the driven rotation process, thereby causing it to be separated from the winding roller 11.
[0042] In order to solve the above problems, Figure 1-2As shown, in a preferred embodiment provided by the present invention based on the above embodiment, an anti-slip sleeve 21 is sleeved on the guide roller 20, and both ends of the anti-slip sleeve 21 are at least partially and equidistantly exposed from the guide roller 20; wherein, the outer wall of the anti-slip sleeve 21 is circumferentially provided with pressing comb teeth 22 along its normal direction, and the pressing comb teeth 22 are used to press the film bag on the winding roller 11; the end of the pressing comb teeth 22 is sleeved with a flexible sleeve head 23, and the flexible sleeve head 23 replaces the end of the pressing comb teeth 22 to rest on the film bag.
[0043] In this embodiment, by providing an anti-slip sleeve 21 on the guide roller 20 and fixing it on the guide roller 20, and by adding a pressing comb 22 on the anti-slip sleeve 21, the pressure exerted by the guide roller 20 on the film bag can be enhanced, and the contact area between the two can be reduced, which can effectively prevent the guide roller 20 from sticking to the film bag, so that the film bag can be stably wound by the winding roller 11. In this embodiment, the flexible sleeve 23 is provided to protect the film bag surface from being punctured and damaged by the tip of the pressing comb 22.
[0044] In order to facilitate the removal of the fully loaded film bag on the winding roll 11 and the replacement of the new roll, as Fig.12 As shown, in a preferred embodiment provided by the present invention based on the above-mentioned embodiment, a detachable inner cylinder 111 is provided on the winding roller 11, and the inner cylinder 111 and the winding roller 11 are fixed by a limiting sleeve 112; wherein, after the inner cylinder 111 is inserted into the winding roller 11, an annular space is left, and the limiting sleeve 112 is inserted from both ends of the winding roller 11 and embedded in the annular ends of the annular space at the same time; the limiting sleeve 112 is limited against the winding roller 11 by a limiting screw 113.
[0045] In this embodiment, when the film bag is fully rolled up on the winding roller 11, it is necessary to replace the inner cylinder 111 to realize the packaging operation of the film bag. After the replacement of the inner cylinder 111 is completed, the head of the film bag is assisted by the guide roller 20 to be rewound on the inner cylinder 111 at least one circle, and then the film bag is rewound onto the newly replaced inner cylinder 111 through the rotation of the winding roller 11 to form a new roll.
[0046] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
