Description

Technical Field

[0001] The utility model relates to the technical field of sealing and laminating of eyeglass packaging bags, in particular to a bag opening sealing cover folding device of an eyeglass packaging bag. Background Art

[0002] After the spectacle lenses are cast, they are usually packed into packaging bags A, such as Figure 1 As shown, the packaging bag A is composed of a bag body 1 and a bag cover 2 integrally formed with the bag body 1. Before the eyeglasses are put into the bag body 1, information such as parameters of the eyeglasses will be printed on the bag body 1 so that sellers and others can identify the information of the eyeglasses.

[0003] When the packaging bag A containing the lenses arrives at the seller, it needs to go through the process of handling and transportation. During this process, if the mouth of the packaging bag is not closed, the lenses are likely to fall out of the packaging bag. Therefore, in the current technology, the usual practice is to fold the bag mouth cover 2 along the mouth of the bag body 1 and insert the folded bag mouth cover 2 into the bag body 1, so that the mouth of the bag body 1 is in a closed state, thereby preventing the lenses from falling out of the packaging bag.

[0004] In addition, simply inserting the bag cover 2 into the bag body 1 cannot completely ensure that the bag cover 2 will not be removed from the bag body 1. For example, during transportation, if the eyeglass lens is subjected to a large vibration force, the impact force generated by the eyeglass lens on the bag cover 2 may cause the bag cover 2 to be removed from the bag body 1. Therefore, a sealing sticker is currently used to stick the bag cover 2 to the bag body 1. After the sealing sticker is stuck, it not only plays a role in firmly fixing the bag cover 2 to the bag body 1, but also plays a role similar to a seal, that is, the lens can only be taken out by destroying the sealing sticker or the packaging bag.

[0005] The above-mentioned method of folding the bag cover 2 and inserting the bag cover 2 into the bag body 1, as well as the method of sticking the bag cover 2 to the bag body 1 with a sealing sticker, were all done manually in the early days. The disadvantage of manual operation is that the cost is high.

[0006] Although, with the advancement of technology, mechanical equipment has been used to fold the bag cover 2, but the existing mechanical equipment, when operating, absorbs the packaging bag A and directly folds the bag cover 2 through the folding mechanism. Then, before folding the bag cover 2, the bag cover 2 is parallel to the bag body 1, and direct folding easily causes the bag cover 2 to be skewed (such as Figure 2 ), resulting in the bag mouth cover 2 being unable to form a closed state for the mouth of the bag body 1 well.

DETAILED DESCRIPTION

[0030] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] like Figure 3 to Figure 4 As shown, the automatic sealing device for eyeglass packaging bags includes a frame 10, a packaging bag conveying device 20, a first driving mechanism 30, a crease forming device 40, and a folding mechanism 50. Each part and the relationship between the parts are described in detail below:

[0032] The packaging bag conveying device 20 is slidably matched with the frame 10. The structure of the packaging bag conveying device 20 is the prior art, for example, the packaging bag conveying device disclosed in CN117002778A is adopted. Therefore, the structure of the packaging bag conveying device in the utility model is not repeated here. A first slide rail 10a is provided on the frame 10, and a slider is provided at the bottom of the packaging bag conveying device 20. The slider and the first slide rail 10a are slidably combined to form a sliding match. The packaging bag conveying device 20 is used to receive the packaging bag A containing the eyeglass lens, and is driven by the first driving mechanism 30 to move from the starting position to the position corresponding to the crease forming device 40.

[0033] The first driving mechanism 30 drives the packaging bag conveying device 20 to reciprocate on the frame 10, and the first driving mechanism 30 is connected to the packaging bag conveying device 20. Since the packaging bag conveying device 20 receives the packaging bag A at the first position (the first position is a position corresponding to the discharge port of the lens packaging machine) and unloads the packaging bag A at the second position (the second position is a position aligned with the fold forming device 40), there is a distance between the first position and the second position. Therefore, the first driving mechanism 30 is used to drive the packaging bag conveying device 20 to switch between the first position and the second position.

[0034] The crease forming device 40 cooperates with the packaging bag conveying device 20 to form a crease on the bag mouth cover 2 on the packaging bag A. The crease forming device 40 includes a first adsorption component 41, a first support plate 42, and a crease generating component. The structure of the first adsorption component 41 is the prior art and is not described here. The first adsorption component 41 is connected to the first support plate 42. The crease generating component includes a connecting seat 43a and a protrusion 43b. One end of the connecting seat 43a is fixed to the first support plate 42, and the protrusion 43b is arranged at the other end of the connecting seat 43a. An L-shaped notch 43c is formed between the protrusion 43b and the connecting seat 43a. The end surface of the other end of the connecting seat 43a is located on the same plane as the adsorption surface of the first adsorption component 41.

[0035] The crease forming device 40 further includes a first linear driver 44, the power output end of which is fixed to the first support plate 42. The first linear driver 44 can be a cylinder, a hydraulic cylinder, an electric screw, etc. In the present invention, the first linear driver 44 preferably uses a cylinder. When the packaging bag conveying device 20 conveys the packaging bag A to the position corresponding to the crease forming device 40, the first linear driver 44 drives the first support plate 42 to move the first adsorption component 41 and the crease generating component toward the packaging bag conveying device 20, and at the same time, the packaging bag conveying device 20 pushes the packaging bag A therein to move toward the crease forming device 40.

[0036] The crease forming device 40 also includes a lifting adjustment mechanism for adjusting the height of the first linear drive 44. The lifting adjustment mechanism includes a fixed seat 45 and a first lifting drive 46. The fixed seat 45 is fixed to the first lifting drive 46, and the first linear drive 44 is fixed to the fixed seat 45. The first lifting drive 46 can be a cylinder, a hydraulic cylinder, an electric screw mechanism, a manual screw mechanism, etc. In this embodiment, a manual screw mechanism is preferably used. The height position of the crease forming device 40 is adjusted by the lifting adjustment mechanism, thereby adjusting the height position of the packaging bag A adsorbed by the first adsorption component 41.

[0037] The folding mechanism 50 folds the bag cover 2 with the crease and keeps the folded state of the bag cover 2, and the folding mechanism 50 is located on one side of the crease forming device 40. The folding mechanism 50 includes a rotary driver 51, a first connecting component 52, a folding arm 53, and a second adsorption component 54 for adsorbing the bag cover 2. The rotary driver 51 preferably adopts a rotary cylinder, the output end of the rotary driver 51 is fixed to the first connecting component 52, the folding arm 53 is fixed to the first connecting component 52, and the second adsorption component 54 is connected to the folding arm 53. The structure of the second adsorption component 54 is the same as that of the first adsorption component 41, and will not be repeated here.

[0038] The working process of the utility model is:

[0039] After the packaging bag A containing the eyeglass lenses enters the packaging bag conveying device 20, the first driving mechanism 30 drives the packaging bag conveying device 20 to move to a position corresponding to the crease forming device 40. The packaging bag conveying device 20 pushes the packaging bag A containing the eyeglass lenses toward the crease forming device 40. At the same time, the first linear driver 44 drives the first supporting plate 42 to move the first adsorption component 41 and the crease generating component toward the packaging bag conveying device 20. The bag body 1 of the packaging bag A is adsorbed by the first adsorption component 41, and the vertical bag cover 2 is bent by the compression of the protrusion 43b. When the bag cover 2 and the upper end of the bag body 1 enter the L-shaped notch 43c, a part of the bag body 1 cooperates with the end face of the other end of the connecting seat 43a, and the upper surface of a part of the bag cover 2 cooperates with the lower surface of the protrusion 43b. The angle formed by the bag cover 2 and the bag body 1 is 90°. At this time, the bag body 1 is adsorbed by the first adsorption component 41 so that the position of the entire packaging bag A remains unchanged, and the second adsorption component 54 applies adsorption force to the bag cover 2, and the bag cover 2 is adsorbed by the second adsorption component 54. The rotary drive 51 works, and the rotary drive 51 drives the first connecting component 52 and the folding arm 53 to rotate 90 degrees, and the second adsorption component 54 drives the bag cover 2 to rotate 90 degrees, so that a fold is formed at the root of the bag cover 2.
