Description

Technical Field

[0001] The utility model relates to the technical field of circular knife machines, in particular to a docking type continuous material changing device. Background Art

[0002] Circular knife machines are now more and more widely used in various industries. With the update of products, the process is becoming more and more complicated. Some products require a variety of different materials to be compounded, resulting in an increase in the number of rolls during unloading. As a result, when the rolls are about to be unloaded, new rolls need to be used to connect the old rolls to ensure production;

[0003] At present, the general practice is to manually replenish and switch the material rolls after the equipment is shut down. However, equipment shutdown will result in no output, and it is very troublesome to restart some equipment after shutdown. The process needs to be readjusted, and manual material connection cannot meet the simultaneous material change. When the number of material rolls increases, the time occupied by manual material change will gradually increase, which in disguise reduces the machine operation time and affects the equipment utilization rate.

[0004] Therefore, a docking type continuous material changing device is needed to solve the above problems. Utility Model Content

[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 sticking plates are all configured to be compatible arcs.

[0011] As a preferred technical solution, each of the pasting plate driving components includes a pasting plate driving cylinder arranged along the X-axis direction, a first slide rail is fixedly installed on the piston rod of each of the pasting plate driving cylinders, a tape pasting plate is slidably installed on each of the first slide rails along the Y-axis direction, and a limit assembly is arranged between each of the first slide rails and the corresponding tape pasting plate.

[0012] As a preferred technical solution, each of the limiting components includes a pull-out handle installed on the corresponding tape adhering plate, each of the pulling handles is hinged with a limit plate, the free end of each limit plate is provided with a limit groove, each of the first slide rails is provided with a limit bolt, and the screw of each limit bolt passes through the corresponding limit groove and is threadedly installed on the corresponding first slide rail.

[0013] As a preferred technical solution, a waste discharge assembly for discharging waste cut from the new material strip is provided on both sides of the material strip positioning and clamping assembly, and each of the waste discharge assemblies includes a waste discharge roller and a traction rubber roller, and the two waste discharge rollers are rotatably mounted on the frame, and two mounting plates are hinged on the frame, and each of the traction rubber rollers is rotatably mounted on the corresponding mounting plate through a rubber roller drive motor, and each of the rubber roller drive motors is mounted on the corresponding mounting plate, and a compression spring is provided between each mounting plate and the frame to make the outer peripheral surface of the traction rubber roller press against the outer peripheral surface of the corresponding waste discharge roller.

[0014] As a preferred technical solution, a plurality of guide shafts for guiding the head of a new material strip are arranged downstream of the two material strip cutting positions, each of the guide shafts extends along the Y-axis direction, and each of the guide shafts is mounted on the frame.

[0015] As a preferred technical solution, a second slide rail is provided on the frame, a slider is slidably installed on the second slide rail, the cache roller is rotatably installed on the slider, a rodless cylinder is provided on the frame along the X-axis direction, and the slider is slidably installed on the frame along the X-axis direction through the rodless cylinder.

[0016] By adopting the above technical solution, the beneficial effects of the utility model are as follows:

[0017] Since the docking type continuous material changing device includes a material tape positioning and clamping component and a cutting and gluing component, when using this device, if an old material tape is placed on the unwinding shaft near the cutting blade, a new material tape is placed on the other unwinding shaft, and the material head of the new material tape passes through between the partition and the first clamping plate near the new material roll, and then is guided by the guide shaft, and finally passes through between the waste discharge roller and the traction rubber roller near the new material roll, and the new material tape is clamped and positioned by the corresponding first clamping plate and partition, the two tape pasting plates are pulled out and the tape is placed on the inner side of the two tape pasting plates, and under the action of the air pump, the two tapes are adsorbed on the inner side of the tape pasting plates, and the two tape pasting plates are reset and limited, thus completing the preparation work before material changing.

[0018] When changing materials, the old material strip is first positioned and clamped by the positioning and clamping assembly. Under the drive of the mounting frame driving cylinder, the cutting blade and the knife groove move to the waiting cutting position. Under the drive of the cutting blade driving cylinder and the knife groove driving cylinder, the cutting blade and the knife groove cooperate to cut the two material strips at the same time. After the two material strips are cut, the waste of the new material strip is discharged under the action of the waste discharge assembly. 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 tail of the old material strip is drawn away, that is, the waste discharge is completed, and then on the mounting frame Driven by the driving cylinder, the two tape pasting plates move to the tape connection position, and then the pasting plate driving cylinder is used to paste the two tapes on both sides of the tape connection position respectively. The material tape positioning and clamping assembly and the cutting adhesive assembly are reset to complete a docking-type material replacement of the material tape. In the utility model, the two material tapes are positioned and clamped by the tape positioning and clamping assembly, the two material tapes after positioning and clamping are cut by the cutting adhesive assembly, and the two tapes are pasted on both sides of the position to be connected respectively, thereby realizing automatic and continuous material replacement of the material tape without stopping the machine, improving the material connection efficiency while ensuring the accuracy of the material connection, and thereby reducing the impact of material replacement on the material tape production efficiency.

[0019] Since the partition, the two first clamping plates, the two second clamping plates and the two tape pasting 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 two material strips 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 pasting. 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.

[0020] The setting of two first clamping plates and one partition plate realizes the separate positioning and clamping of the new material strip and the old material strip. After cutting the two material strips, the device can discharge the tail of the old material strip without affecting the positioning and clamping of the head of the new material strip, thereby avoiding the influence of the position of the head of the new material strip when discharging waste materials, thereby improving the accuracy of material connection.

[0021] Since the two tape sticking plates are both mounted on the corresponding mounting frames by a limiting assembly, when the tape needs to be placed, the two limiting plates are rotated, and the screw rods of the two limiting bolts are moved out of the corresponding limiting holes, thereby releasing the lock of the two tape sticking plates, so that the tape sticking plates can be pulled out along the Y-axis direction and the tape can be placed. After the tape sticking plates are pulled out, the operating space for placing the tape is increased, which facilitates manual placement of the tape.

[0022] Since the docking type continuous material changing device includes two waste discharge components, each waste discharge component includes a waste roller and a traction rubber roller. Under the action of the compression spring, the outer peripheral surface of each traction rubber roller is pressed against the outer peripheral surface of the corresponding waste discharge roller. After the new material roll is placed, the head of the new material roll is positioned between the waste discharge roller and the traction rubber roller. After the two material strips are cut, the traction rubber roller rotates under the drive of the rubber roller driving motor to discharge the waste of the new material strip. In the utility model, the waste discharge component plays a role of positioning and clamping the head of the new material strip after the new material roll is installed, and the waste discharge component plays a role of discharging the waste of the new material strip after the two material strips are cut. One component realizes two functions, which simplifies the structure of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] A cutting blade driving cylinder 31 and a knife groove driving cylinder 32 are respectively installed on the two mounting frames 6.

[0043] Two unloading shaft driving motors 33 are arranged on the frame 1 , and each unloading shaft driving motor 33 is drivingly connected to the corresponding unloading shaft 2 .

[0044] The adsorption holes 10 are all connected to an air pump, which is not shown in the figure.

[0045] The method of using the utility model is as follows:

[0046] In the first step, before changing the material, the two first clamping plates 4, the two second clamping plates 5, the two tape sticking plates 9, the cutting blade 7 and the knife groove 8 are all in a separated state. If the old material strip is placed on the discharge shaft 2 near the cutting blade 7, the old material strip passes between the first clamping plate 4 and the partition plate 3 near the cutting blade 7, and then passes between the two second clamping plates 5. After being guided by the guide roller 12 and cached by the cache roller 11, it moves forward normally along the forward direction of the material strip.

[0047] In the second step, the new material roll is placed on another unwinding shaft 2, and the material head of the new material belt passes through between the partition 3 and the other first clamping plate 4, and then is guided by the guide shaft 24, and then passes through between the corresponding waste discharge roller 19 and the traction rubber roller 20. Under the action of the first clamping plate driving cylinder 29 close to the new material belt, the new material belt is pressed between the partition 3 and the corresponding first clamping plate 4. At this time, the new material belt between the first clamping plate 4 and the traction rubber roller 20 is guaranteed to be in a taut state.

[0048] The third step is to rotate the two limiting plates 16 to release the limiting of the two tape pasting plates 9, pull out the two tape pasting plates 9 along the Y-axis direction, and place the two tapes on the inner sides of the two tape pasting plates 9 respectively. Under the action of the air pump, a negative pressure is formed at the adsorption holes 10, and the two tapes are adsorbed on the inner sides of the corresponding tape pasting plates 9. After the tapes are adsorbed, push the two tape pasting plates 9 to reset along the Y-axis direction, rotate the two limiting plates 16, and the screws of the two limiting bolts 18 are respectively located in the corresponding limiting grooves 17. The two tape pasting plates 9 are limited, and the placement of the tapes on both sides is completed.

[0049] The fourth step is to start material replacement. The unloading shaft 2 with the old material belt placed on it stops working. Under the action of the first clamping plate driving cylinder 29 close to the old material belt, the corresponding first clamping plate 4 moves along the direction of the X-axis towards the direction close to the partition 3 until the old material belt is pressed against between the corresponding first clamping plate 4 and the partition 3. At the same time, under the action of the second clamping plate driving cylinder 28, the two second clamping plates 5 move along the direction of the X-axis towards the direction close to the old material belt until the old material belt is clamped, thus completing the positioning and clamping of the old material belt. At this time, the new material belt and the old material belt upstream of the guide roller 12 are both in a stationary state, and the old material belt cached by the cache roller 11 downstream of the guide roller 12 provides material for non-stop processing of subsequent material belts.

[0050] In the fifth step, the position to be cut is located between the two first clamping plates 4 and the two second clamping plates 5. After the two material strips are positioned and clamped, the two mounting frames 6 are driven by the two mounting frame driving cylinders 30 and move simultaneously along the direction of the Z axis, and the cutting blade 7 and the knife groove 8 are moved to the position to be cut. Then, driven by the cutting blade driving cylinder 31 and the knife groove driving cylinder 32, the cutting blade 7 and the knife groove 8 are moved in the direction close to the two material strips, that is, the two material strips are cut simultaneously at the position to be cut.

[0051] The sixth step, after the two material strips are cut at the same time, under the drive of the two mounting frame driving cylinders 30, the two mounting frames 6 move simultaneously along the direction of the Z axis, and the two tape pasting plates 9 move to the cutting position. At the same time, under the action of the first clamping plate driving cylinder 29, the first clamping plate 4 close to the old material roll moves along the direction of the X axis away from the partition 3, and the tail of the old material strip wound on the unwinding shaft 2 is separated from the clamping of the partition 3 and the first clamping plate 4. Under the action of the corresponding unwinding shaft 2, the tail of the old material strip is drawn away. At the same time, under the drive of the rubber roller driving motor 22, the traction rubber roller 20 rotates, that is, the waste of the new material strip is discharged.

[0052] In the seventh step, after the tailings of the old material and the waste of the new material strip are discharged, the two tape pasting plates 9 are driven by the two pasting plate driving cylinders 13 to move closer to the position to be connected, that is, the two tapes are pasted on both sides of the position to be connected at the same time, thus completing a docking-type automatic material change of the material strips.

[0053] Step 8. After the two tapes are pasted, the first clamping plate 4, the second clamping plate 5 and the two tape pasting plates 9 are reset to prepare for the next material change. At this time, the unwinding shaft 2 with the new material roll 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 unwinding shaft 2 near the cutting blade 7.

[0054] In summary, the utility model realizes automatic and continuous material replacement of material strips without stopping the machine by butting and pasting the new and old material strips, thereby improving the material splicing efficiency while ensuring the accuracy of the material splicing.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
