Description
Technical Field
[0001] The utility model relates to an auxiliary device for splicing lining paper of high-speed cigarette packaging equipment. Background Art
[0002] The high-speed development of cigarette manufacturing equipment is the future development direction of cigarette machine equipment. In order to ensure smooth operation, reduce the impact of the internal transmission structure caused by frequent speed increase and speed decrease, and also to ensure that the equipment operation efficiency is at a high level, high-speed cigarette packaging equipment, mainly the ZB416 series packaging machine, mostly adopts dynamic splicing of auxiliary materials, that is, the splicing of auxiliary materials such as lining paper and inner frame paper is completed while ensuring that the equipment operation speed remains unchanged or slightly reduced. Taking the ZB416 high-speed packaging machine as an example, when splicing the lining paper, the lining paper tightening roller will first release a certain amount of margin to ensure that the speed of the paper tape near the incision position is relatively static during the splicing action so that the tape can be pasted and spliced. However, due to the influence of factors such as inertia during the operation of the paper tape, the cut paper tape still has a speed of moving downstream at the splicing point. This phenomenon will cause gaps to appear at the joints after the lining paper is spliced, which will affect the normal splicing of the paper tape and cause it to break. In severe cases, the paper tape will be abnormal and rolled into other parts of the equipment, resulting in damage and failure. Utility Model Content
[0003] In order to solve the above technical problems, the utility model proposes an inner lining paper splicing auxiliary device for high-speed cigarette packaging equipment to help the high-speed cigarette packaging equipment to complete the stable splicing of auxiliary materials such as inner lining paper.
[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] The splicing mechanism includes a splicing cutter, a positioning block, and a tape sticking block that can swing toward / away from the splicing position of the inner liner paper respectively;
[0007] The separation guide plate is suspended parallel to the inner lining paper tape in use and the inner lining paper tape to be used, and is located above the inner lining paper splicing part, and a gap is left between the plate surface and the inner lining paper tape in use and the inner lining paper tape to be used respectively;
[0008] The conveying and supporting mechanism for the inner lining paper tape in use is located at the rear side of the splicing mechanism as a whole, and includes a guide upper pressure roller, a guide lower pressure roller, an adsorption guide plate, and a conveying guide plate, which are vertically aligned, arranged in sequence from top to bottom, and have gaps between them. The guide upper pressure roller and the guide lower pressure roller rotate in the same direction at a constant speed, and the speed is adjustable. The front side plate surfaces of the adsorption guide plate and the conveying guide plate serve as working surfaces, and are vertically flush with the front side outer roller surfaces of the guide upper pressure roller and the guide lower pressure roller. The width of the working surfaces is greater than the width of the inner lining paper tape in use. The working surface of the adsorption guide plate is provided with a plurality of adsorption holes connected to an external negative pressure pipeline. When the negative pressure is connected, the adsorption of the inner lining paper tape in use on the working surface can be maintained by relying on the negative pressure through each adsorption hole. The inner lining paper tape in use passes through the gap between the guide upper pressure roller and the guide lower pressure roller, and is pulled between the guide upper pressure roller and the guide lower pressure roller. The upper end extends horizontally and backward, and is conveyed to the downstream station from bottom to top as a whole. The lower end is cantilevered and contacts with the working surfaces of the adsorption guide plate and the conveying guide plate.
[0009] The standby inner lining paper tape guide mechanism is located above the splicing mechanism and in front of the inner lining paper tape conveying and supporting mechanism in use. It includes a pair of traction rollers spaced apart in front and back and of equal height. The upper end of the standby inner lining paper tape is supported and pulled by a pair of traction rollers relying on the outer roller surface. The upper end extends upward and horizontally forward, and the whole is conveyed from bottom to top. The lower end is cantilevered and separated from the inner lining paper tape in use by a separation guide plate. The paper tape faces each other and is parallel to each other.
[0010] At the lining paper splicing part, the positioning pressing block swings back and forth between the original position and the paper pressing position, the splicing cutter swings back and forth between the original position and the paper cutting position, and the adhesive tape pasting pressing block swings back and forth between the original position and the pasting position. There is a spacing in the front-to-back direction between the positioning pressing block, the splicing cutter, the adhesive tape pasting pressing block and the lining paper splicing part at the original position. The lining paper tape in use and the lining paper tape to be used at the lining paper splicing part are pressed on the working surface of the conveying guide plate by the positioning pressing block at the paper pressing position with a vertical and flat pressing surface. The splicing cutter at the paper cutting position cuts with its blade at the gap between the adsorption guide plate and the conveying guide plate. Corresponding to the cutting position, the stand-by liner paper tape is bounded by the cutting position. The above part is reset to its original position as the splicing cutter from the paper cutting position. An upward displacement is generated through contact with the splicing cutter. With the cutting position as the boundary, the cut surfaces of the stand-by liner paper tape and the upper part of the liner paper tape in use are bonded by the tape carried by the tape bonding block at the bonding position, thereby forming a splicing of the liner paper tape in use and the stand-by liner paper tape.
[0011] The structural features of the utility model also lie in:
[0012] The working surface of the adsorption guide is made of self-lubricating nylon.
[0013] The adsorption guide plate is a cavity structure, a negative pressure pipeline is led out from one side of the plate body through a pipe joint, and each adsorption hole is connected to an external negative pressure gas source through the negative pressure pipeline.
[0014] The adhesive tape pasting pressing block at the pasting position is pasted between the standby inner lining paper tape and the cut surface of the part above the cut position of the inner lining paper tape in use by means of the adhesive tape carried by the vertical and flat pasting surface.
[0015] The inner lining paper tape conveying and supporting mechanism in use also includes a guide roller, which is vertically aligned and arranged below the conveying guide plate, leaving a gap between the outer roller surface and the conveying guide plate in the vertical direction, and the outer roller surface is vertically aligned with the working surface of the conveying guide plate, and contacts the lower end of the inner lining paper tape in use through the outer roller surface.
[0016] Compared with the prior art, the beneficial effects of the utility model are embodied in:
[0017] The utility model is used for stabilizing the inner lining paper tape when high-speed cigarette packaging equipment splices the inner lining paper tape to be used with the inner lining paper tape in use, thereby improving the accuracy and stability of the splicing. The negative pressure suction of the adsorption guide plate is used to stably adsorb the inner lining paper tape in use that has been cut to avoid it from falling. The separation guide plate is used to keep the inner lining paper tape in use and the inner lining paper tape to be used separated, so that when the cut surfaces of the inner lining paper tape in use and the inner lining paper tape to be used are spliced, the position of the joint can be more stable and accurate, thereby avoiding the appearance of gaps between the paper tapes after splicing.

[0032] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0033] Please refer to Figures 1 to 6 The liner paper splicing auxiliary device of the high-speed cigarette packaging equipment of this embodiment includes:
[0034] The splicing mechanism includes a splicing cutter 11, a positioning pressing block 12, and a tape sticking pressing block 13, which can swing toward / away from the splicing position of the inner liner paper respectively;
[0035] The separation guide plate 2 is suspended in parallel between the lining paper tape in use and the lining paper tape to be used, and is located above the splicing part of the lining paper, and there are gaps between the plate surface and the lining paper tape in use and the lining paper tape to be used respectively;
[0036] The inner lining paper tape conveying and supporting mechanism in use is located at the rear side of the splicing mechanism as a whole, and includes a guide upper pressure roller 31, a guide lower pressure roller 32, an adsorption guide plate 33, and a conveying guide plate 34, which are vertically aligned and arranged in sequence from top to bottom with gaps left between them. The guide upper pressure roller 31 and the guide lower pressure roller 32 rotate in the same direction at a constant speed, and the speed is adjustable. The front side plate surfaces of the adsorption guide plate 33 and the conveying guide plate 34 serve as working surfaces, which are vertically flush with the front side outer roller surfaces of the guide upper pressure roller 31 and the guide lower pressure roller 32, and the width of the working surface is greater than the width of the inner lining paper tape in use. The working surface of the adsorption guide plate 33 is provided with a plurality of adsorption holes 333 connected to the external negative pressure pipeline 332. When the negative pressure is turned on, the adsorption holes 333 can rely on the negative pressure to maintain the adsorption of the inner lining paper tape in use on the working surface. The inner lining paper tape 6 in use passes through the gap between the guide upper pressure roller 31 and the guide lower pressure roller 32, and is pulled by the guide upper pressure roller 31 and the guide lower pressure roller 32. The upper end of the inner lining paper tape 6 extends upward and horizontally backward, and is transported from bottom to top to the downstream station as a whole. The lower end of the inner lining paper tape 6 is suspended and contacts the working surfaces of the adsorption guide plate 33 and the transport guide plate 34.
[0037] The standby inner lining paper tape guide mechanism is located above the splicing mechanism and in front of the inner lining paper tape conveying and supporting mechanism in use, and includes a pair of traction rollers 4 spaced apart and of equal height. The upper end of the standby inner lining paper tape 7 is supported and pulled by the pair of traction rollers 4 on the outer roller surface, and the upper end extends upward and horizontally forward, and the whole is conveyed from bottom to top. The lower end is cantilevered and separated from the inner lining paper tape in use by the separation guide plate 2, and the paper tapes are opposite and parallel to each other in front and back.
[0038] At the lining paper splicing part, the positioning pressing block 12 reciprocates between the original position and the paper pressing position, the splicing cutter 11 reciprocates between the original position and the paper cutting position, and the adhesive tape pasting pressing block 13 reciprocates between the original position and the pasting position. There is a spacing between the positioning pressing block 12, the splicing cutter 11, and the adhesive tape pasting pressing block 13 in the original position and the lining paper splicing part in the front-to-back direction. The lining paper tape in use and the lining paper tape to be used at the lining paper splicing part are pressed on the working surface of the conveying guide 34 by the positioning pressing block 12 in the paper pressing position with a vertical and flat pressing surface. On the top, the splicing cutter 11 in the paper cutting position cuts with its blade at the gap between the adsorption guide 33 and the conveying guide 34. Corresponding to the cut position, the stand-by liner paper tape is bounded by the cut position, and the above part is reset to the original position as the splicing cutter 11 from the paper cutting position. The upward displacement is generated by the contact with the splicing cutter 11. The cut surface of the stand-by liner paper tape and the upper part of the liner paper tape in use is bonded by the tape carried by the tape bonding block 13 in the bonding position, forming a splicing of the liner paper tape in use and the stand-by liner paper tape.
[0039] In a specific implementation, the corresponding structural setting of the device also includes:
[0040] The device is installed on the frame 5 as a whole.
[0041] The working surface of the adsorption guide plate 33 is made of self-lubricating nylon material, which can reduce the friction force on the paper tape when the inner lining paper tape is adsorbed during its running process.
[0042] The adsorption guide plate 33 is a hollow structure, and a negative pressure pipeline 332 is led out from one side of the plate body through a pipe joint 331 , and each adsorption hole 333 is connected to an external negative pressure gas source through the negative pressure pipeline 332 .
[0043] The adhesive tape pasting pressing block 13 at the pasting position is pasted between the standby inner lining paper tape and the cut surface of the inner lining paper tape in use above the cut position by means of the adhesive tape carried by the vertical and flat pasting surface 131 .
[0044] The inner lining paper tape conveying and supporting mechanism in use also includes a guide roller 35, which is vertically aligned and arranged below the conveying guide plate 34, leaving a gap between the conveying guide plate 34 in the vertical direction, and the front side of the outer roller surface is vertically aligned with the working surface of the conveying guide plate 34, and contacts the lower end of the inner lining paper tape in use through the outer roller surface.
[0045] During use, the lining paper tape is located between the separation guide and the adsorption guide, and the height position of the lower edge of the separation guide is slightly higher than the height position of the gap between the adsorption guide and the conveying guide to avoid interference with the splicing cutter cutting paper.
[0046] The above-mentioned splicing and cutting mechanism is an existing structure of the high-speed cigarette packaging equipment, and the reciprocating swing of the positioning block, splicing cutter, and adhesive tape pasting block is also an existing function of the high-speed cigarette packaging equipment. As another optional scheme: through reciprocating swing, the positioning block switches between the original position and the paper pressing position, the splicing cutter switches between the original position and the paper cutting position, and the adhesive tape pasting block switches between the original position and the pasting position. The implementation means can also be to configure independent driving devices for the positioning block, the splicing cutter, and the adhesive tape pasting block respectively. For example, one end of the positioning block is sleeved on the positioning shaft, and the positioning shaft is driven to reciprocate by the corresponding driving device, thereby driving the positioning block to swing back and forth around the central axis of the positioning shaft between the original position and the paper pressing position. The reciprocating swing of the splicing cutter and the adhesive tape pasting block is the same.
[0047] This device can be used in conjunction with high-speed cigarette packaging equipment. It is set at the position where the equipment splices the inner lining paper. When the splicing cutter in the splicing mechanism splices and replaces the inner lining paper, this device stabilizes the inner lining paper belt and improves the splicing accuracy and stability. The working process example is as follows:
[0048] When in the state of waiting for splicing, the lining paper tape in use is closely attached to the working surface of the conveying guide plate and the adsorption guide plate, and is transported upward and backward under the traction of the upper guide roller and the lower guide roller. The adsorption guide plate uses negative pressure to adsorb the lining paper tape in use through the adsorption holes. The use of self-lubricating nylon material prevents the friction force on the paper tape from being too large. The lining paper tape to be used is placed on the front side of the separation guide plate from bottom to top, and is transported upward and forward under the traction of a pair of traction rollers.
[0049] When performing the splicing action, the upper guide roller and the lower guide roller first increase their rotation speeds to convey more of the lining paper tape in use to the downstream workstation, in preparation for normal use when the device slows down for splicing; subsequently, the rotation speeds of the upper guide roller and the lower guide roller decrease rapidly, causing the running speed of the lining paper tape in use to decrease accordingly, and the positioning pressing block swings backwards rapidly to the paper pressing position, pressing the standby lining paper tape and the lining paper tape in use at the same time at the lining paper splicing position; thereafter, the splicing cutter swings backwards to the paper cutting position, cutting the standby lining paper tape and the lining paper tape in use at the same time at the gap between the adsorption guide plate and the conveying guide plate, with the cutting position as the boundary, at this time, the upper part of the lining paper tape in use is completely adsorbed on the adsorption plate under the action of negative pressure adsorption. The guide plate working surface has its movement speed at the cut-off point reduced to 0, and the lower part naturally falls off the conveying guide plate under the action of gravity; after the splicing cutter completes the cutting, it returns to its original position immediately. During this process, the upper part of the standby lining paper tape bounded by the cut-off point contacts the splicing cutter, and produces an upward displacement as the splicing cutter is reset. At this time, the separation guide plate plays an auxiliary supporting role for the lining paper tape in use adsorbed on the adsorption guide plate working surface, preventing it from being lifted up at the same time as the standby lining paper tape, thereby avoiding the appearance of a splicing gap; subsequently, the adhesive tape pasting block swings backward to the pasting position, and the adhesive tape that has been placed on its pasting surface in advance is pasted between the cut-off surface of the standby lining paper tape and the lining paper tape in use, thereby completing the splicing of the lining paper;
[0050] After the splicing is completed, the positioning block, splicing cutter and tape pasting block are in place, and the guide upper pressure roller and the guide lower pressure roller resume rotation. The pulling force applied to the liner paper tape makes the liner paper tape tight, which can overcome the adsorption force of the adsorption guide plate and resume normal operation, and transport it to the downstream station.
[0051] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
