一种可适应多卷径规格的封卷尾机构Sealing tail mechanism capable of adapting to multiple winding diameter specifications
本发明涉及卷状材料的生产加工设备技术领域，尤其涉及一种可适应多卷径规格的封卷尾机构。The invention relates to the technical field of production and processing equipment for rolled materials, in particular to a sealing tail mechanism which can adapt to a multi-roll diameter specification.
现有的卷筒在收卷后会在尾端使用胶水黏合进行封尾，以保持卷筒的稳定性，采用胶水粘合的封尾方式有以下三个缺点：第一，在使用前将卷尾撕开的过程中会破坏与尾端相黏合的卷筒外圈，使尾端的一部分不能正常使用；第二，由于胶水有一定的渗透性，一些情况下往往会黏住内层的纸，造成用户需要撕去多层才能使用，不仅浪费材料，而且操作不方便；第三，在现有的卷筒尾端封尾中要使用大量的胶水，不仅需要增加额外的材料成本，而且胶水是一种化学合成材料，具有一定的有害成分，而且具有一定的挥发性，无论是在生产过程中或者使用时均会对工人或者用户的健康产生负面的影响，并且大量胶水的使用不利于环保。The existing reel will be sealed with glue at the end after winding to maintain the stability of the reel. The sealing method using glue bonding has the following three disadvantages: First, the roll will be used before use. During the tearing process, the outer ring of the reel which is bonded to the tail end is destroyed, so that a part of the tail end cannot be used normally; secondly, due to the certain permeability of the glue, in some cases, the inner layer of paper is often adhered. The user needs to tear off the multi-layer to use, which not only wastes materials, but also is inconvenient to operate. Thirdly, a large amount of glue is used in the tail end sealing of the existing reel, which not only requires additional material cost, but also glue is one. A kind of chemical synthetic material has certain harmful components and has certain volatility. It will have a negative impact on the health of workers or users during the production process or during use, and the use of a large amount of glue is not conducive to environmental protection.
基于上述原因，本申请人于2015.11.12提交了名称为“一种卷筒无胶环保封尾的方法及卷筒”的发明专利申请，其公开号为CN 105293196A，公开日为2016.02.03。具体地，利用机械压合的方式对卷筒尾端进行压合，其过程无需采用胶水。然而申请人在该专利中仅公开了其加工的方法，并未公开实现该方法的具体设备结构。Based on the above reasons, the applicant filed an invention patent application entitled "A Method and Reel for a Reel-free Environmental Sealing of a Reel" on 2015.11.12, the publication number is CN 105293196A, and the publication date is 2016.02.03. Specifically, the end of the reel is press-fitted by mechanical pressing, and the process does not require glue. However, the Applicant only discloses the method of its processing in this patent, and does not disclose the specific device structure for implementing the method.
然而，上述的专利文件只公开了其工作方式，并没有公开其具体的设备结构；公开号为CN101674993A、CN104755400A的专利申请虽然公开了机械方式形成折叠部，但是它们效率低下，并不能一次性在卷筒尾端形成封尾。此外申请人在后续的实施过程中，发现现有技术仍存在以下不足：对于不同卷径的卷筒在进行封卷时，其模头的开合幅度必须要与卷径适配，假如模头的开合幅度过小，难以对多圈卷纸进行压合，使卷筒尾部容易散开；假如模头的开合幅度过大，则在进行压合时需要利用较高的压力进行压合，否则难以将卷尾部分压紧封卷。若模头在同一设备上的开合幅度不变，就需要针对不同卷径的卷筒配置不同的设备，使厂家的前期成本投入巨大，因此需要设计出一种能适应多种不同卷径的封卷机构。However, the above-mentioned patent documents only disclose the mode of operation thereof, and do not disclose the specific device structure thereof; while the patent applications published as CN101674993A and CN104755400A disclose mechanically forming the folded portions, they are inefficient and cannot be used at one time. The end of the roll forms a seal. In addition, in the subsequent implementation process, the applicant found that the prior art still has the following deficiencies: when the reel of different reel diameters is sealed, the opening and closing range of the die must be adapted to the winding diameter, if the die is used. The opening and closing range is too small, it is difficult to press the multi-roll paper, so that the tail of the reel is easy to spread; if the opening and closing of the die is too large, it is necessary to press with a higher pressure during the pressing. Otherwise, it is difficult to press the tail portion tightly. If the opening and closing amplitude of the die on the same device is the same, it is necessary to configure different devices for the reels of different roll diameters, so that the initial cost of the manufacturer is huge, so it is necessary to design a machine that can adapt to a variety of different winding diameters. Sealing mechanism.

参见图6和图7所示，本实施例中的钳臂21的头部均设置有夹模安装座25和夹模24，所述夹模安装座25与夹模24之间通过连接螺栓26连接，并且夹模安装座25在其外侧面螺纹连接有多个调节螺栓27，该多个调节螺栓27沿夹模安装座25的宽度方向布置并贯穿夹模安装座25对夹模24顶压以调节两夹模24之间的平行度。具体地当两夹模24闭合时，若两夹模24之间出现局部的缝隙时，对旋转对应缝隙位置处的调节螺栓27，从而调节两者的平行度消除两者之间的缝隙。在本实施例中，夹模24的夹嘴241凸出于其内侧面，同时两夹模24均在其夹嘴241上成形有相互啮合的细齿242。也可以根据实际需要在两夹模24中择一设置细齿242，利用细齿242能提高夹模24闭合时的压强使卷纸压合更加紧密。Referring to FIG. 6 and FIG. 7 , the heads of the caliper arms 21 in this embodiment are each provided with a clamp mounting seat 25 and a clamping die 24 , and the clamping die mounting seat 25 and the clamping die 24 are connected by a connecting bolt 26 . Connected, and the die mount 25 is screwed on its outer side with a plurality of adjusting bolts 27 arranged along the width direction of the die mount 25 and pressed against the clamp 24 through the die mount 25 To adjust the parallelism between the two jaws 24.

驱动单元3一侧移动时，伸缩驱动单元3与封尾夹2之间的距离更小，从而使钳臂21的可打开幅度更小，适用于卷径较小的卷筒；当水平滑块4背向伸缩驱动单元3一侧移动时，伸缩驱动单元3与与封尾夹2之间的距离更大，从而使钳臂21的可打开幅度更大，适用于卷径较大的卷筒。The sealing tail mechanism of the present embodiment works as follows: First, the worker adjusts the opening and closing range of the caliper arm 21 according to the current winding diameter of the reel, and specifically, the rotating screw 51 slides the horizontal slider 4 in the horizontal direction when the level Slider 4 telescopic
When the driving unit 3 moves on one side, the distance between the telescopic driving unit 3 and the sealing clip 2 is smaller, so that the openable range of the caliper arm 21 is smaller, and is suitable for a reel having a smaller winding diameter; 4 When the back of the telescopic drive unit 3 moves, the distance between the telescopic drive unit 3 and the tail clamp 2 is larger, so that the openable range of the clamp arm 21 is larger, and is suitable for a reel having a larger winding diameter. .
封尾夹2的两钳臂21在伸缩驱动单元3的推动下开合，由于两钳臂21以及两连杆22相互首尾铰接，因此当其中一根钳臂21受伸缩驱动单元3推动而摆动时，另一根钳臂21也同时受带动进行反向摆动，实现两钳臂21同步开合，使卷筒被夹持时均匀受力，避免卷筒在封尾时受损。在第一夹模21a和第二夹模21b开口时，控制它们的弧形切面与卷筒4切面夹角大于15度小于50度，夹角可以通过销轴进行调节。这样便于夹嘴214与卷筒形成合适的受力部位，以给予卷筒足够的夹力使其能够紧密结合，又不至于夹力过大损坏卷筒。The two caliper arms 21 of the sealing clip 2 are opened and closed by the telescopic driving unit 3, and since the two caliper arms 21 and the two connecting rods 22 are hinged to each other, one of the caliper arms 21 is swayed by the telescopic driving unit 3 At the same time, the other caliper arm 21 is also driven to perform reverse swing, so that the two caliper arms 21 are synchronously opened and closed, so that the reel is evenly stressed when being clamped, and the reel is prevented from being damaged during sealing. When the first jaw 21a and the second jaw 21b are opened, the angle between the curved section of the control and the section of the reel 4 is controlled to be greater than 15 degrees and less than 50 degrees, and the angle can be adjusted by the pin. This facilitates the formation of a suitable force receiving portion of the gripper 214 and the reel to give the reel a sufficient clamping force to enable it to be tightly coupled without damaging the reel by excessive clamping force.
