Description

Technical Field

[0001] The utility model relates to the field of laminating machines, in particular to an anti-film-jamming structure and a laminating machine. Background Art

[0002] When the laminator is laminating, the closed end is normally placed at the front end and inserted into the glue inlet to complete the laminating and film coating normally. If the open end is placed at the front end and inserted into the glue inlet, the two pieces of film will stick tightly to and adhere to the curved surface of the rubber roller after passing through the high-temperature rubber roller, causing the front end of the film to fork and roll outward along its respective curved surfaces, and eventually the film will be stuck between the rubber roller and the special-shaped aluminum, resulting in failure of laminating and film coating.

[0018] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only."

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] like Figure 1 and Figure 2 As shown, an anti-film jamming structure is characterized in that it includes a shell, the shell is provided with a glue inlet 1 and a glue outlet 2, two corresponding rubber rollers 3 are provided in the shell, a guide part 4 is provided on the outside of the rubber roller 3, and the guide part 4 extends to the position of the glue inlet 1, a plurality of annular grooves 31 are provided on the outside of the rubber roller 3, and a limiting rope 5 is provided at the position of the annular groove 31, one end of the limiting rope 5 is fixed to the outside of the first fixed shaft 61, and the other end of the limiting rope 5 is fixed to the second fixed shaft 62 by a tension spring 7, the first fixed shaft 61 and the second fixed shaft 62 are respectively located on both sides of the rubber roller 3, and the limiting rope 5 is in contact with the outer side of the guide part 4.

[0022] Under the action of the tension spring 7, the limit rope 5 is tightened and set at the outer side of the rubber roller 3. In this way, the limit rope 5 is tightened and not easy to loosen, and the operation is reliable. At this time, since the two limit ropes 5 are clamped in the annular groove 31 of the rubber roller 3, even if the film is placed incorrectly, the film can be prevented from winding around the outer side of the rubber roller 3. The film will be guided out along the channel between the two limit ropes 5, thereby realizing the anti-film jamming function.

[0023] At this time, two groups of the first fixed shaft 61 and the second fixed shaft 62 are set, and each group corresponds to a rubber roller 3. At this time, the first fixed shaft 61 and the second fixed shaft 62 are respectively located on both sides of the rubber roller 3. In this way, the limiting rope 5 tightened and fixed between the first fixed shaft 61 and the second fixed shaft 62 can pass through the annular groove 31 of the corresponding rubber roller 3. Since multiple annular grooves 31 and limiting ropes 5 are set, during use, if the rubber film is placed in the wrong direction and tends to be wound to the outside of the rubber roller 3, it will be blocked by the limiting rope 5 and continue to move along the direction of the limiting rope 5, so as to be exported at the glue outlet 2.

[0024] At this point, the gap between the two limiting ropes 5 represents the moving position of the film. Therefore, in this embodiment, to ensure smooth film delivery from the laminating outlet 2, the spacing between the two limiting ropes 5 is greater on the side closer to the laminating outlet 2 than on the side closer to the laminating inlet 1. The limiting ropes 5 between the two rubber rollers 3 form an "eight" shape, with the spacing gradually increasing near the laminating outlet 2 until they are fixed to the first fixed shaft 61. This further increases the spacing near the laminating outlet 2, facilitating the film delivery process.

[0025] In order to extend the service life of the limiting rope 5, in this embodiment, the limiting rope 5 is a steel wire rope. At this time, since the limiting rope 5 is in contact with the rubber roller 3, which has a certain temperature, the use of a steel wire rope as the limiting rope 5 can prevent the limiting rope 5 from being damaged during use, thereby affecting the normal use of the anti-jamming function.

[0026] At the same time, the limiting ropes are spaced apart from each other at the contact positions of the two rubber rollers. Specifically, multiple limiting ropes are provided with the two rubber rollers, and the limiting ropes corresponding to the two rubber rollers are alternately spaced apart. This can increase the distribution density of the limiting ropes, thereby achieving a better anti-film jamming effect.

[0027] Since the ends of the limiting rope 5 are respectively positioned with the first fixed shaft 61 and the second fixed shaft 62, in order to prevent the ends of the limiting rope 5 from sliding on the first fixed shaft 61 and the second fixed shaft during use, in this embodiment, the surfaces of the first fixed shaft 61 and / or the second fixed shaft 62 are provided with positioning grooves corresponding to the limiting rope 5, and the ends of the limiting rope 5 and / or the tension spring 7 are clamped in the positioning grooves. After the positioning grooves are provided, the ends of the positioning rope can be fixed in the positioning grooves, and the middle of the limiting rope 5 is clamped in the annular groove 31 of the rubber roller 3, which can better position the limiting rope 5, prevent the limiting rope 5 from sliding left and right during use, and further prevent the limiting rope 5 from affecting the normal gluing and heat sealing process.

[0028] The two rubber rollers 3 are in contact with each other, and the rubber film passes between the two rubber rollers 3 to complete the glue heat sealing. Therefore, the rubber rollers 3 need to have a certain temperature to achieve heat sealing. In this embodiment, a heating sheet 8 is provided on the outside of the rubber rollers 3, and the heating sheet 8 is spaced apart from the rubber rollers 3. The external heating sheet 8 transfers the temperature to the rubber rollers 3 through heat radiation, thereby heating the rubber rollers 3.

[0029] In order to better transfer the heat from the heating element 8 to the rubber roller 3, in this embodiment, a heat conducting member 9 is provided on the outside of the rubber roller 3, which is arranged around the rubber roller 3. The heat conducting member 9 has an opening near the contact position of the two rubber rollers 3, and the two rubber rollers 3 abut at the opening of the rubber roller 3. After the heat conducting member 9 is provided around the rubber roller 3, the heat transferred by the heating element is more evenly transferred to the position of the rubber roller 3. In addition, when the rubber roller 3 rotates, the temperature of the rubber roller 3 is more uniform during use, thereby ensuring a better heat sealing effect.

[0030] Furthermore, in order to better transfer the temperature of the heating sheet 8 to the heat-conducting member 9, in this embodiment, a fixing groove 91 is provided inside the heat-conducting member 9. The fixing groove 91 opens toward the rubber roller 3, and the heating sheet 8 is fixed in the fixing groove 91. By arranging the heating sheet 8 inside the heat-conducting member 9, the heating member can better and faster transfer heat to the heat-conducting member 9, thereby achieving stable heating of the rubber roller 3.

[0031] The guide member 4 is positioned at the gluing entrance 1 to guide the incoming film. Therefore, in this embodiment, the guide member 4 is a lateral extension of the heat-conducting member 9. The guide member 4 comprises a horizontal portion and an arc portion, with the outer side of the arc portion being closer to the gluing entrance 1. In this case, by positioning the guide member 4 as part of the heat-conducting member 9, the guide member 4 also maintains a certain temperature, allowing for preliminary heating of the film entering the gluing entrance 1, thereby improving the heat sealing effect during the gluing process.

[0032] Since the guide member 4 has a certain temperature and the limiting rope 5 is located at the outer side of the guide member 4, in order to avoid excessive contact between the limiting rope 5 and the film during use and leave marks on the surface of the film, in this embodiment, the outer side of the guide member 4 is provided with a groove corresponding to the limiting rope 5, and the limiting rope 5 is clamped in the groove. The limiting rope 5 is not higher than the outer side surface of the guide member 4. In this way, the film will not contact the limiting rope 5 at the position of the guide member 4, but will only contact the outer arc surface of the guide member 4, thereby realizing the normal entry of the film.

[0033] The utility model also provides an embodiment, a laminating machine, which adopts the above-mentioned anti-film-jamming structure.

[0034] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
