Description

Technical Field

[0001] The utility model relates to the technical field of material strip processing, in particular to a device for cutting and gluing new and old material strips. Background Art

[0002] During the production process of the material tape, when the old material roll on the unwinding shaft is almost used up, the old material tape needs to be spliced. The common method is to use a splicing platform to manually place and limit the new and old material tapes on the operating panel, and then manually cut the new and old material tapes, and then discharge the cut new material tape waste and the old material tape tail, and then stick the tape on one side of the position to be connected. The traditional method not only fails to achieve double-sided gluing at the position to be connected, making the connection strength between the new and old material tapes weak and easy to break during the production process, but also requires manual limitation, cutting and gluing of the new and old material tapes, which reduces the efficiency of cutting and gluing the new and old material tapes, thereby affecting the processing efficiency of the material tape.

[0003] Therefore, a device for cutting and gluing new and old material strips that can solve the above-mentioned problems is needed. Utility Model Content

[0004] The utility model provides a new and old material tape cutting and gluing device, which realizes automatic cutting of the new and old material tapes after clamping and positioning through the coordinated cooperation of the cutting component and the gluing component, and sticks tapes on both sides of the butt joint position.

[0005] The technical solution of the utility model is achieved in this way:

[0006] The device for cutting and gluing new and old material tapes comprises a frame, on which a clamping and positioning assembly for clamping and positioning the new material tape and the old material tape is arranged, the frame is also provided with a cutting assembly for cutting the new material tape and the old material tape after clamping and positioning, and a gluing assembly for respectively sticking two tapes on both sides of the docking position, two sliding frames are slidably mounted on the frame along the Z-axis direction, the two sliding frames are respectively arranged on both sides of the clamping and positioning assembly, the cutting assembly comprises a cutting knife and a knife groove which are relatively arranged, the cutting knife is slidably mounted on one of the sliding frames along the X-axis direction, and the knife groove is slidably mounted on the other sliding frame along the X-axis direction, the gluing assembly comprises two tape adsorption plates which are relatively arranged, the inner side of each of the tape adsorption plates is provided with an adsorption hole for adsorbing the tape, and each of the sliding frames is equipped with a tape adsorption plate through an adsorption plate driving assembly.

[0007] As a preferred technical solution, each of the adsorption plate driving components includes an adsorption plate driving cylinder arranged along the X-axis direction, a slide rail is fixedly installed on the piston rod of each of the adsorption plate driving cylinders, and a tape adsorption plate is slidably installed on each of the slide rails along the Y-axis direction, and a limit assembly is arranged between each of the slide rails and the corresponding tape adsorption plate.

[0008] As a preferred technical solution, each of the limiting components includes an upper limiting plate hinged to the corresponding tape adsorption plate, a limiting groove is provided at the free end of each of the limiting plates, a limiting bolt is provided on each of the sliding rails, and the screw of each of the limiting bolts passes through the corresponding limiting groove and is threadedly installed on the corresponding sliding rail.

[0009] As a preferred technical solution, the clamping assembly positioning includes a partition fixedly installed on the frame, the partition is vertically arranged, and a first clamping plate for clamping and positioning the new material strip and the old material strip upstream of the cutting position is arranged on both sides of the partition, and each of the clamping plates is slidably installed on the frame along the X-axis direction, and a pair of second clamping plates for clamping and positioning the old material strip downstream of the cutting position are arranged downstream of the partition, and each of the second clamping plates is slidably installed on the frame along the X-axis direction.

[0010] As a preferred technical solution, in order to make the extension direction of the material strip after cutting consistent with the forward direction of the material strip, the partition, the two first clamping plates, the two second clamping plates and the two tape adsorption plates are all configured to be adaptive arcs.

[0011] As a preferred technical solution, two unwinding shafts for placing material rolls are rotatably mounted on the frame, and both of the unwinding shafts are arranged upstream of the clamping and positioning assembly.

[0012] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0013] Since the device for cutting and gluing new and old material tapes includes a cutting component and a gluing component, when using this device, if the old material tape is placed on the unwinding shaft near the cutting knife, place the new material tape on the other unwinding shaft, pass the material head of the new material tape between the partition and the first clamping plate near the new material roll, and pull it down to the downstream of the cutting position, pull out the two tape adsorption plates and place the tape on the inner side of the two tape adsorption plates, under the action of the air pump, the two tapes are adsorbed on the inner side of the tape adsorption plates, reset and limit the two tape adsorption plates, and the preparation work before material replacement is completed.

[0014] The material change starts. Under the drive of the sliding frame driving cylinder, the cutting knife and the knife groove move to the waiting cutting position. Under the drive of the cutting knife driving cylinder and the knife groove driving cylinder, the cutting knife and the knife groove cooperate to cut the new material strip and the old material strip at the same time. After the new material strip and the old material strip are cut, the waste of the new material strip is discharged manually or by a waste discharge device. Under the action of the first clamping plate driving cylinder, the first clamping plate close to the old material roll moves away from the partition, and the tail of the old material strip placed on the unwinding shaft releases the clamping lock. Under the rotation of the unwinding shaft, the old material strip is The tail is pulled away, that is, the waste is discharged, and then the two tape adsorption plates are moved to the tape connection position by the driving cylinder of the sliding frame, and then the two tapes are respectively pasted on both sides of the tape connection position by the adsorption plate driving cylinder, and the tape positioning clamping component and the cutting and gluing component are reset to complete the cutting and gluing of a new tape and an old tape. In the utility model, through the coordinated cooperation of the cutting component and the gluing component, the new tape and the old tape after clamping and positioning are automatically cut at the same time, and the tapes are pasted on both sides of the docking position.

[0015] Since the new and old material tape cutting and gluing device includes a clamping and positioning assembly, the first clamping plate and the partition plate cooperate with each other to realize the separate positioning and clamping of the new and old material tapes upstream of the cutting position. After cutting the new and old material tapes, the device can discharge the tail of the old material tape without affecting the positioning and clamping of the head of the new material tape, thereby avoiding the position deviation of the new material tape caused by discharging the tail of the old material tape and improving the accuracy of the docking and material replacement of the new and old material tapes.

[0016] Since the two tape adsorption plates are installed on the corresponding sliding frame through a limit assembly, when the tape needs to be placed, the two limit plates are rotated, and the screws of the two limit bolts are moved out from the corresponding limit holes, thereby releasing the lock of the two tape adsorption plates, so that the tape adsorption plates can be pulled out along the Y-axis direction and the tape can be placed. After the tape adsorption plates are pulled out, the operating space for placing the tape is increased, which facilitates manual placement of the tape.

[0017] Since the partition, the two first clamping plates, the two second clamping plates and the two tape adsorption plates are all arranged in an arc shape and matched with each other, the head of the old material strip is the material strip downstream of the cutting position. After the new material strip and the old material strip are cut, under the action of the two second clamping plates, the head of the old material strip is positioned and clamped, and at the same time, both sides of the head of the old material strip are bent toward the middle with a certain arc, so that the extension direction of the head of the material strip is consistent with the forward direction of the material strip, that is, the end of the head of the old material strip is prevented from bending in the perpendicular direction of the forward release direction of the material strip after cutting, causing the failure of tape sticking. Under the action of the middle partition and the corresponding first clamping plate, both sides of the head of the new material strip are bent toward the middle with a certain arc, so as to be consistent with the head of the old material strip, thereby improving the accuracy of docking.

[0035] The adsorption holes 6 are all connected to an air pump, which is not shown in the figure.

[0036] The method of using the utility model is as follows:

[0037] In the first step, before cutting and gluing the new and old material tapes, the two first clamping plates 13, the two second clamping plates 14, the two tape adsorption plates 5, the cutting knife 3 and the knife groove 4 are all in a separated state. If the old material tape is placed on the discharge shaft 15 near the cutting knife 3, the old material tape passes between the first clamping plate 13 and the partition plate 12 near the cutting knife 3, and then passes between the two second clamping plates 14, and moves forward normally along the forward direction of the material tape.

[0038] In the second step, the new material roll is placed on another unwinding shaft 15, the material head of the new material strip passes through between the partition 12 and the other first clamping plate 13, and is pulled down to the downstream of the cutting position. Under the action of the first clamping plate driving cylinder 16 close to the new material strip, the new material strip is pressed against the partition 12 by the corresponding first clamping plate 13, thus completing the clamping and positioning of the new material strip.

[0039] The third step is to rotate the two limit plates 9 to release the limit of the two tape adsorption plates 5, pull out the two tape adsorption plates 5 along the Y-axis direction, and place the two tapes on the inner sides of the two tape adsorption plates 5 respectively. Under the action of the air pump, a negative pressure is formed at the adsorption holes 6, and the two tapes are adsorbed on the inner sides of the corresponding tape adsorption plates 5. After the tapes are adsorbed, push the two tape adsorption plates 5 to reset along the Y-axis direction, rotate the two limit plates 9, and the screws of the two limit bolts 11 are respectively located in the corresponding limit grooves 10. The two tape adsorption plates 5 are limited, and the placement of the tapes on both sides is completed.

[0040] In the fourth step, under the action of the first clamping plate driving cylinder 16 close to the old material strip, the old material strip upstream of the cutting position is pressed against the partition 12 by the corresponding first clamping plate 13, and under the action of the two second clamping plate driving cylinders 17, the two second clamping plates 14 move along the direction of the X-axis toward the direction close to the old material strip until the old material strip downstream of the cutting position is clamped, thereby completing the clamping and positioning of the old material strip.

[0041] In the fifth step, the cutting position is located between the two first clamping plates 13 and the two second clamping plates 14, and the cutting of the new material strip and the old material strip begins. The unloading shaft 15 on which the old material strip is placed stops working. After the new material strip and the old material strip are clamped and positioned, the two sliding frames 2 move simultaneously along the Z-axis direction under the drive of the two sliding frame driving cylinders 18, and the cutting knife 3 and the knife groove 4 move to the cutting position, and then under the drive of the cutting knife driving cylinder 19 and the knife groove driving cylinder 20, the cutting knife 3 and the knife groove 4 move towards the direction close to the new material strip and the old material strip, that is, the new material strip and the old material strip are cut simultaneously at the cutting position.

[0042] The sixth step is to remove the waste of the new material tape cut from the new material tape manually or through a waste discharge device after the new material tape and the waste of the old material tape cut from the new material tape are removed manually or through a waste discharge device. Driven by the two slide frame driving cylinders 18, the two slide frames 2 move simultaneously along the direction of the Z axis, and the two tape adsorption plates 5 move to the cutting position. At the same time, under the action of the first clamping plate driving cylinder 16, the first clamping plate 13 close to the old material roll moves along the direction of the X axis away from the partition 12, and the tail of the old material tape wound on the unwinding shaft 15 is separated from the clamping of the partition 12 and the first clamping plate 13. Under the action of the corresponding unwinding shaft 15, the tail of the old material tape is drawn away.

[0043] In the seventh step, after the tailings of the old material and the waste of the new material tape are discharged, the two tape adsorption plates 5 are driven by the two adsorption plate driving cylinders 7 to move closer to the position to be connected, thus completing the gluing of the new material tape and the old material tape on both sides of the position to be connected.

[0044] In the eighth step, after the two tapes are pasted, the first clamping plate 13, the second clamping plate 14 and the two tape adsorption plates 5 are reset. At this time, the unloading shaft 15 with the new material roll placed on it starts to rotate, and the new material tape replaces the old material tape and continues to run. When the material is changed next time, the new material roll is placed on the unloading shaft 15 near the cutting knife 3.

[0045] In summary, the utility model realizes the simultaneous automatic cutting of the new material strip and the old material strip after clamping and positioning through the coordinated cooperation of the cutting component and the gluing component, and the gluing of tapes on both sides of the docking position.
