Referring to fig. 1-5, the present embodiment provides an automatic roll changing mechanism 100 for completing a roll changing operation in a tape adhering apparatus 300, wherein the automatic roll changing mechanism 100 includes a worktable 110, a material preparing unit 120, a rotating unit, a detecting unit 140, and a material clamping unit 150; in order to detachably receive the material roll and discharge the used material roll, the rotating unit may include an air shaft 130 and a motor (not shown) for driving the air shaft 130 to rotate. It will be understood that the rotating unit may also be in the form of a three-jaw chuck, which can grip an unused roll/discharge a used roll, and can grip the reel of the roll and perform rotation to achieve the taking and releasing of the roll and the unwinding of the adhesive tape.

The stock preparation unit 120 is connected to the work table 110 and is used for placing at least one stock roll 10; the inflatable shaft 130 is used for clamping the material roll 10, and the inflatable shaft 130 is movably connected with the workbench 110 along a first preset direction (as shown by an arrow B in FIG. 1) and is provided with a loading position for loading the material roll 10 and a discharging position for removing the material roll 10; the detection unit 140 is connected to the air expansion shaft 130 and is used for detecting the allowance of the material roll 10 clamped on the air expansion shaft 130; the material clamping unit 150 is movably connected to the table 110 along a first predetermined direction, and has a material clamping position for clamping the material roll 10 in the material preparing unit 120, and a loading position for loading the clamped material roll 10 into the air-expansion shaft 130 at the loading position.

Referring to fig. 1-5, the automatic reel changer 100 operates as follows:

the automatic roll changing mechanism 100 can detect the allowance of the material roll 10 clamped on the air expansion shaft 130 through the detection unit 140, and can stop to change the roll when the allowance of the adhesive tape on the material roll 10 reaches the preset amount of the roll change;

before the reel change action is performed, the air shaft 130 needs to be reversed to withdraw the released adhesive tape portion; then, the material roll 10 on the air expansion shaft 130 can be moved to the discharging position through the movement of the air expansion shaft 130 along the first preset direction, and then the material roll 10 on the air expansion shaft 130 can be moved out at the discharging position;

after the material roll 10 on the air expansion shaft 130 is moved out, the air expansion shaft 130 can move to the loading position along the first preset direction;

then moving to a clamping position along a first preset direction through the clamping unit 150, clamping out one of the material rolls 10 in the preparation units 120, and loading the clamped material roll 10 to a loading position of the air expansion shaft 130 at a loading position through the movement along the first preset direction;

thus, the roll change operation is completed;

as can be seen from the above, in the process of performing the roll change operation, the automatic roll change mechanism 100 can complete the detection of the remaining amount of the material roll 10 through the detection unit 140, and further automatically perform the subsequent roll change operation, thereby reducing the number of the attended staff and reducing the labor intensity of the attended staff; in the process of changing the coil, the air expansion shaft 130 can automatically unload materials, and meanwhile, the loading position is the position for releasing the material coil 10 in the normal working state, so that the moving stroke of the air expansion shaft 130 can be reduced, and the loading action can be quickly completed through the position change of the clamping unit 150 between the clamping position and the loading position in the process of changing the coil; that is, the operations of the discharging and charging steps can be simplified to improve the efficiency of reel change, thereby shortening the time required for reel change and the time required for shutdown of reel change, thereby improving the productivity.

Further, referring to fig. 1-5, in the present embodiment, in order to improve the stability of the material roll 10 loaded on the air shaft 130 during the loading process and prevent the material roll 10 from being separated from the air shaft 130 during the releasing process of the adhesive tape, the automatic roll changing mechanism 100 further includes a pressing head 160, and the pressing head 160 is movably connected to the air shaft 130 along a second predetermined direction (as shown by an arrow C in fig. 1) and has a pressing position and a spacing position; the first preset direction is vertical to the second preset direction;

when the pressing head 160 is in the pressing position, the pressing head 160 is used for pressing the material roll 10 clamped on the air expansion shaft 130 so as to limit the movement of the material roll 10 in the direction away from the air expansion shaft 130; when the pressing head 160 is in the spaced position, the pressing head 160 is spaced from the air shaft 130, and the spaced area between the air shaft 130 and the pressing head 160 is used for the material roll 10 to pass through.

Therefore, when the inflatable shaft 130 is in a state of normally releasing the adhesive tape, the pressing head 160 which is out of the liquid pressing position can limit the movement of the material roll 10 along the direction of separating from the inflatable shaft 130, thereby maintaining the installation stability of the material roll 10; furthermore, in order to prevent the clamp head from limiting the movement of the to-be-removed material roll 10 or the to-be-loaded material roll 10 during the process of releasing or loading a new material roll 10 by the inflatable shaft 130, the clamp head 160 further includes a spacing position, when the spacing position is located, the spacing area between the clamp head 160 and the inflatable shaft 130 can be used for the material roll 10 to pass through, so that the clamp head can be prevented from limiting the movement of the to-be-removed material roll 10 or the to-be-loaded material roll 10, and the normal operation of the to-be-removed material roll 10 and the loaded material roll 10 can be ensured.

Based on the above, please refer to fig. 1 to 5, in the present embodiment, in order to control the movement of the air shaft 130, the movement of the material clamping unit 150 and the movement of the pressing head 160 in the above, so as to improve the automation degree and the operation stability of the automatic roll changing mechanism 100, therefore, the automatic roll changing mechanism 100 further includes a first driving unit 101, a second driving unit 102 and a third driving unit 103;

the first driving unit 101 is used for driving the air expansion shaft 130 to change positions between a loading position and a discharging position along a first preset direction; the second driving unit 102 is configured to drive the clamping unit 150 to change positions between the clamping position and the loading position along a first preset direction; the third driving unit 103 is configured to drive the pressing head 160 to change positions between the pressing position and the spacing position along the second preset direction. It should be noted that, when the first driving unit 101, the second driving unit 102 and the third driving unit 103 are disposed, the motion form between the two positions may adopt a linear motion mode, and thus, a linear driving structure in the prior art, such as one or more of a track moving structure, a motor moving structure or a screw transmission structure, may be adopted, and the specific driving structure and driving principle thereof are not described herein again.

Further, referring to fig. 1-5, in the present embodiment, the automatic roll changing mechanism 100 further includes a cutting unit 170 and a fourth driving unit 104;

the cutting unit 170 is movably connected to the worktable 110 along a third predetermined direction (as shown by an arrow D in fig. 1), and the fourth driving unit 104 is configured to drive the cutting unit 170 to move along the third predetermined direction, and has a feeding position and a material cutting position; the first preset direction, the second preset direction and the third preset direction are vertical to each other;

when the cutting unit 170 is in the upper tape position, the cutting unit 170 is for receiving an external adhesive tape; when the cutting unit 170 is in the cutting position, the cutting unit 170 is used to cut the adhesive tape.

As can be seen from the above, through the arrangement of the cutting unit 170, when the cutting unit 170 is located at the material cutting position, the cutting unit 170 performs the cutting operation of the adhesive tape, so that the required adhesive tape can be cut quickly, and the adhesive tape sticking efficiency can be improved; in addition, in order to match the roll changing operation in the above structure, the cutting unit 170 further includes a feeding position, and when the cutting unit 170 is located at the feeding position, the cutting unit 170 is configured to receive an external adhesive tape, that is, the cutting unit 170 can match the inflatable shaft 130 and the material clamping unit 150 to complete the tape threading operation of the tape after roll changing, so that the automatic roll changing mechanism 100 can quickly perform the tape threading operation of the roll 10 after roll changing, and further improve the working efficiency of the automatic roll changing mechanism 100.

Specifically, when the cutting unit 170 is provided, the cutting unit 170 includes a main body 171, a cutting portion 172, and a fifth driving unit 105;

Thus, when the roll changing operation is completed, the fourth driving unit 104 drives the main body 171 to change from the cutting position to the upper belt position; meanwhile, the fifth driving unit 105 drives the cutting part 172 to change from the cutting position to the threading position, so that the channel on the main body 171 is opened, so that the external adhesive tape can move into the channel, i.e. the tape threading action is completed; after the threading is completed, the fourth driving unit 104 drives the main body 171 to change from the feeding position to the cutting position, and meanwhile, the fifth driving unit 105 drives the cutting portion 172 to change from the threading position to the cutting position, so that the cutting portion 172 can cut the adhesive tape, and the threading can be completed quickly.

In addition, the automatic reel changing mechanism 100 further includes an attaching bar 180 connected to the stock preparation unit 120, the attaching bar 180 being used to attach the free end of the roll 10 in the stock preparation unit 120. It should be noted that the attaching rod 180 is used for attaching the free end of the material roll 10 in the preparation unit 120, so as to facilitate the subsequent tape threading operation, and the free end of the material roll 10 can be manually operated when being attached to the attaching rod 180.

Therefore, the free end of the material roll 10 attached to the attaching rod 180 can be clamped by the tape threading clamping jaw 190, and the clamping position is changed to the tape threading position after the free end of the material roll 10 is clamped under the driving action of the sixth driving unit 106, so that the adhesive tape can be moved into the channel, and the tape threading action is completed; before the belt threading position is changed, the fourth driving unit 104 drives the main body 171 to change from the cutting position to the upper belt position; meanwhile, the fifth driving unit 105 has driven the cutting part 172 to change from the tape cutting position to the tape passing position, so that the channel on the main body 171 is opened, and the adhesive tape between the tape threading clamping jaw 190 and the air expansion shaft 130 can be moved into the channel in the process of changing the tape threading clamping jaw 190 from the clamping position to the tape threading position, thereby completing the tape threading action.
