Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mechanical equipment, in particular to a structure and process for uninterrupted material replacement. BACKGROUND

[0002] In the fields of die cutting, printing, packaging and material processing, the production line usually uses a feeder to perform directional feeding treatment on the material belt. The material belt is driven by the feeder and moves directionally to the next production and processing process.

[0003] In related technologies, the feeder usually includes a rack and a feeding roller rotatably arranged on the rack. In use, a material belt roll is sleeved and fixed on the feeding roller, and the feeding roller rotates to directionally feed the material belt.

[0004] However, the feeder in the related art can only feed a single material belt roll. When the material belt on the material belt roll is used up, the machine needs to be stopped, a new material belt roll needs to be reinstalled on the feeding roller, and then the machine can continue to work. This material replacement method is time-consuming and labor-intensive, and the production efficiency is low. SUMMARY

[0005] In order to improve the phenomenon that the feeder in the related art can only feed a single material belt roll, when the material belt on the material belt roll is used up, the machine needs to be stopped, a new material belt roll needs to be reinstalled on the feeding roller, and then the machine can continue to work. This material replacement method is time-consuming and labor-intensive, and the production efficiency is low, the present application provides a structure and process for uninterrupted material replacement.

[0006] The purpose of the present application is to provide a structure for uninterrupted material replacement, which adopts the following technical scheme:

[0007] A structure for uninterrupted material replacement includes a rack, a feeding follower device and a material belt traction device arranged on the rack, the feeding follower device is provided with two groups, and the two groups of feeding follower devices are symmetrically arranged on the rack;

[0008] The feeding follower device includes a feeding roller rotatably arranged on the rack and a following adhesive mechanism arranged on the rack, the two feeding rollers can be independently driven to rotate forward or reverse, the material belt roll is fixedly sleeved on the two feeding rollers, and the following adhesive mechanism is arranged between the feeding roller and the material belt traction device;

[0009] The following adhesive mechanism includes a lifting seat arranged on the rack in a lifting manner, a sliding seat arranged on the lifting seat in a sliding manner, and an adsorption plate arranged on the sliding seat, the sliding seat can slide horizontally on the lifting seat, the adsorption plate is provided with a first vacuum cavity for adsorbing and positioning the material belt, and the adsorption plate is also provided with a lamination assembly for laminating two material belts.

[0010] By adopting the technical scheme, when the uninterrupted material changing structure is used, two material belt rolls are taken out and fixed on two feeding rollers respectively, and the fitting assembly is fixed on one of the adsorption plates.

[0011] The lifting seat carrying the adsorption plate slides upward, the material belt in the material belt roll close to the adsorption plate is pulled out, and the pulled-out material belt is connected with the fitting assembly.

[0012] At this time, the other lifting seat slides upward, the material belt in the material belt roll close to the lifting seat is pulled out, and the pulled-out material belt passes through between the two adsorption plates and the material belt traction device in sequence, so that the material belt roll close to the lifting seat is used as the first material belt roll for normal feeding.

[0013] When the first material belt roll is used close to the end, the adsorption plate close to the first material belt roll adsorbs the material belt in the first material belt roll, so that the material belt in the first material belt roll is not easy to fall off while continuing to feed.

[0014] When the tail end of the material belt in the first material belt roll approaches the fitting assembly, the two sliding seats slide towards each other, so that the two adsorption plates are quickly closed, and the fitting assembly bonds the tail end of the material belt in the first material belt roll with the head end of the material belt which has not been fed. At the same time when the two adsorption plates are quickly closed, the two lifting seats descend along the transmission direction of the material belt, and the descending speed of the two lifting seats is consistent with the transmission speed of the material belt.

[0015] After the fitting assembly bonds the tail end of the material belt in the first material belt roll with the head end of the material belt which has not been fed, the two sliding seats slide away from each other, so as to facilitate the material belt roll which has not been fed as the second material belt roll for feeding.

[0016] When the second material belt roll is fed, the lifting seat close to the second material belt roll slides upward, the fitting assembly is fixed on the adsorption plate away from the second material belt roll, and the third material belt roll is re-fed on the feeding roller away from the second material belt roll.

[0017] The lifting seat close to the third material belt roll slides upward, the material belt of the third material belt roll is pulled out, and the pulled-out material belt is connected with the fitting assembly. After the second material belt roll is used close to the end, the similar steps can be repeated for uninterrupted material changing.

[0022] By adopting the above technical scheme, since the driving gear is in meshing connection with the driven gear and the driven gear is fixed on the adsorption plate, when the driving gear rotates, the adsorption plate can rotate around the wheel shaft of the driven gear, thereby achieving the purpose of overturning the adsorption plate. After the adsorption plate is overturned, one side of the adsorption plate provided with the first vacuum cavity is exposed, thereby facilitating adsorption and fixation of the first adhesive tape on the adsorption plate through the first vacuum cavity.

[0026] By adopting the above technical scheme, the material tape in the material tape roll that is about to be used up is cut off by the cutting mechanism before the material tape roll is connected with the next material tape roll, and the cut end of the cut material tape is flat, thereby facilitating connection with the material tape in the next material tape roll.

[0027] And, when the cutting mechanism cuts the material tape in the material tape roll about to be used up, the distance from the cutting mechanism to the following adhesive mechanism is fixed, so that the time when the tail end of the cut material tape is transported to the fitting assembly can be predicted, thereby facilitating the control of the time when the two suction plates are quickly closed to make the fitting assembly connect the two material tapes more accurately.

[0063] The following will be described in detail with reference to the accompanying drawings. Figure 1 - the accompanying drawings Figure 9 , the present application will be further described in detail.

[0064] Embodiment One:

Among them, the feeding following device 2 is provided with two groups, and the two groups of feeding following devices 2 are symmetrically arranged on the rack 1, and the tape traction device 3 is located below the two groups of feeding following devices 2.

[0066] Referring to Figure 1 , specifically, the feeding following device 2 comprises a feeding roller 21, a cutting mechanism 22 and a following and pasting mechanism 23 arranged in sequence on the rack 1, and the feeding roller 21 is rotatably connected to the rack 1. The feeding roller 21 is located above the cutting mechanism 22, the cutting mechanism 22 is located above the following and pasting mechanism 23, and the following and pasting mechanism 23 is located above the tape traction device 3. In this embodiment, the feeding roller 21 in the two groups of feeding following devices 2 is fixedly sleeved with a tape roll 4, and the two feeding rollers 21 can be independently driven to rotate forward and reverse.

[0067] Referring to Figure 1 , the cutting mechanism 22 comprises an upper roller 221 rotatably connected to the rack 1, a lower roller 222 rotatably connected to the rack 1, and a cutting knife 223 installed on the upper roller 221.

The side of each of the two adsorption plates 233 facing each other is provided with a first vacuum cavity 6 for adsorbing and positioning the tape 41, and the adsorption plate 233 is also provided with a lamination assembly for laminating two tapes 41.

[0069] Referring to Figure 1 and Figure 2 , specifically, the lamination assembly comprises a first adhesive tape 7 adsorbed and fixed on the adsorption plate 233 through the first vacuum cavity 6, and the adhesive surface of the first adhesive tape 7 is located on the side of the first adhesive tape 7 away from the adsorption plate 233.

[0070] Referring to Figure 1 and Figure 2In this embodiment, the adsorption plate 233 is rotatably mounted on the sliding seat 232.

The material belt traction mechanism 24 is located between the feeding roller 21 and the cutting mechanism 22. Specifically, the material belt traction mechanism 24 includes two second traction rollers 241 rotatably connected to the frame 1. The two second traction rollers 241 cooperate to form a second traction groove 12 for feeding the material belt 41 through. The two opposite sidewalls of the material belt 41 respectively abut against the two second traction rollers 241.

[0075] Reference Figure 1In addition, the feeding following device 2 further comprises a plurality of paper guide rollers 25 rotatably connected to the frame 1, which are distributed between the feeding roller 21 and the tape traction mechanism 24, and between the cutting mechanism 22 and the following sticking mechanism 23. In the embodiment, the number of the paper guide rollers 25 in one feeding following device 2 is two, which are respectively located between the feeding roller 21 and the tape traction mechanism 24, and between the cutting mechanism 22 and the following sticking mechanism 23.

[0076] With reference to Figure 1 The frame 1 is provided with two sets of auxiliary sticking mechanisms 13 for assisting in sticking the two tapes 41, which are distributed between the following sticking mechanism 23 and the tape traction device 3. The two sets of auxiliary sticking mechanisms 13 correspond to the two sets of following sticking mechanisms 23 one by one, and the following sticking mechanism 23 and the corresponding auxiliary sticking mechanism 13 are respectively used for sticking the two sides of the joint of the two tapes 41.

[0077] With reference to Figure 1 And Figure 3 Specifically, the auxiliary sticking mechanism 13 comprises a rotating sticking roller 131 rotatably connected to the frame 1 and a rubber wheel 132 rotatably connected to the frame 1, the rotating sticking roller 131 and the rubber wheel 132 are oppositely arranged, and a second through slot 14 for the tape 41 to pass through is formed between the rotating sticking roller 131 and the rubber wheel 132. The rotating sticking roller 131 is provided with a second vacuum cavity 15, and the rotating sticking roller 131 is adsorbed and fixed with a second adhesive tape 16 for assisting in sticking the two tapes 41 through the second vacuum cavity 15, and the adhesive surface of the second adhesive tape 16 is located on the side of the second adhesive tape 16 away from the rotating sticking roller 131.

[0078] With reference to Figure 1 And Figure 3 In the embodiment, the up-and-down positions of the rotating sticking roller 131 and the rubber wheel 132 in the two sets of auxiliary sticking mechanisms 13 are opposite, and the rotating sticking roller 131 in the two sets of auxiliary sticking mechanisms 13 can be independently driven to rotate.

[0079] With reference to Figure 1 In the embodiment, the frame 1 is provided with two tape sensors 17 for detecting the remaining amount of the tape roll 4, and the two tape sensors 17 correspond to the two feeding rollers 21 one by one.

[0080] The implementation principle of the embodiment is that when the structure of the application is used, two tape rolls 4 are taken out first, and the two tape rolls 4 are respectively fixedly sleeved on the two feeding rollers 21, the adhesive surface of the first adhesive tape 7 is adsorbed and fixed on one of the adsorption plates 233, and the adhesive surface of the second adhesive tape 16 is adsorbed and fixed on the rotating sticking roller 131 corresponding to the adsorption plate 233.

[0081] The lifting seat 231 carrying the adsorption plate 233 slides upward, pulls out the tape 41 in the tape roll 4 close to the adsorption plate 233, and then the pulled-out tape 41 is sequentially threaded through the adjacent second traction groove 12 and first threading groove 5, and then is attached to the upper end position of the second adhesive tape 16.

[0082] At this time, the other lifting seat 231 slides upward, pulls out the tape 41 in the tape roll 4 close to the lifting seat 231, and then the pulled-out tape 41 is sequentially threaded through the adjacent second traction groove 12, first threading groove 5, two adsorption plates 233, second threading groove 14, and first traction groove 11, so that the tape roll 4 close to the lifting seat 231 is used as the first tape roll for normal feeding.

[0083] When the first tape roll is used for normal feeding, the tape sensor 17 close to the first tape roll detects the remaining amount of the first tape roll. When the first tape roll is about to be used up, the tape sensor 17 sends a signal, and the cutting mechanism 22 close to the first tape roll cuts the tape 41 for normal feeding in the first tape roll, and the adsorption plate 233 close to the first tape roll adsorbs the cut tape 41, so that the cut tape 41 is not easily dropped while continuing to be fed.

[0084] When the tail end of the cut tape 41 approaches the first adhesive tape 7, the two sliding seats 232 slide towards each other, so that the two adsorption plates 233 quickly close, and after the two adsorption plates 233 close, the first adhesive tape 7 bonds the tail end of the cut tape 41 with the head end of the tape 41 that has not been fed. At the same time that the two adsorption plates 233 quickly close, the two lifting seats 231 descend along the transmission direction of the tape 41, and the descending speed of the two lifting seats 231 is consistent with the transmission speed of the tape 41.

[0085] After the first adhesive tape 7 bonds the tail end of the cut tape 41 with the head end of the tape 41 that has not been fed, the two sliding seats 232 slide away from each other, so as to facilitate the tape roll 4 that has not been fed to be used as the second tape roll for feeding.

[0086] According to the requirements of the product receiving tape, if double-sided tape 41 is required, after the first adhesive tape 7 bonds the tail end of the cut tape 41 with the head end of the tape 41 that has not been fed, the transfer roller 131 with the second adhesive tape 16 adsorbed rotates, the transfer roller 131 drives the second adhesive tape 16 to rotate synchronously, and the second adhesive tape 16 is pasted to the joint of the two tapes 41, at this time, the first adhesive tape 7 and the second adhesive tape 16 are respectively located on both sides of the joint of the two tapes 41, so as to achieve the effect of double-sided adhesive tape of the product.

[0087] When the second material tape roll is fed, the lifting seat 231 close to the second material tape roll slides upward, the adhesive surface of the first adhesive tape 7 is adsorbed and fixed outward on the adsorption plate 233 away from the second material tape roll, the adhesive surface of the second adhesive tape 16 is adsorbed and fixed outward on the transfer roller 131 corresponding to the adsorption plate 233, and the third material tape roll is re-fed on the feeding roller 21 away from the second material tape roll.

[0088] The lifting seat 231 close to the third material tape roll slides upward, the material tape 41 of the third material tape roll is pulled out, and the pulled-out material tape 41 is sequentially threaded through the adjacent second traction groove 12 and the first threading groove 5 and then attached to the upper end position of the second adhesive tape 16.

[0089] The material tape sensor 17 close to the second material tape roll detects the remaining amount of the second material tape roll, and when the second material tape roll is close to being used up, the material tape sensor 17 detects the same and repeats the above steps to continuously change the material.

[0090] Therefore, the application does not need to stop and change the material, and continuously changes the material without stopping, has the effect of saving time and labor in changing the material, and has high production efficiency.
