The figures respectively show the schematic diagrams of the adhesive tape cutting device before mounting the adhesive tape (state I), after mounting the adhesive tape (state II), clamping the adhesive tape (state III), pulling and cutting the adhesive tape (state IV) and completing and resetting the cutting (state V). In the tape cutting apparatus after these 5 steps, the holding portion 1 releases the holding force of the tape a, and then the holding portion 1 is retracted to the position of the state v, thereby preparing for the next cutting. Wherein, the three arrows shown in the state III and the state IV are the moving directions of the components of the adhesive tape cutting device in the process of cutting the adhesive tape A.

Fig. 8 is an enlarged schematic view of the area f in fig. 7, in which the adhesive tape passing through the nip portion 1 is divided into 2 conveying directions, in which the recovery surface B is conveyed to the upper left and peeled off from the adhesive tape a, and the peeled adhesive tape a is pushed to the cutting portion 2.

As shown in fig. 1-8, the adhesive tape cutting device of the present embodiment includes a feeding turntable 4, a receiving turntable 3, a cutting portion 2 and a clamping portion 1, wherein the receiving turntable 3 is used for pulling and recovering a recovering surface B of an adhesive tape a to drive the adhesive tape to convey. The cutting portion 2 has a cutting hole 21, and the cutting hole 21 is used for cutting the adhesive tape a from which the recovery surface B is torn. The clamping part 1 is provided with a clamping block 12 and a guide block 13 which are oppositely arranged, the guide block 13 is provided with a tape guide surface 11 which extends towards the cutting hole 21 and is far away from the material receiving rotary disc 3, the clamping part 1 is configured to move relative to the cutting part 2 and is matched with the material feeding rotary disc 4, so that the adhesive tape A has a tensile force and the recovery surface B is kept attached to the tape guide surface 11. The clamp block 12 and the guide block 13 are configured to clamp the adhesive tape a and to cause the receiving turntable 3 to pull the recovery surface B from the guide block 13 toward the side of the cutting section 2 to peel the recovery surface B from the adhesive tape a.

The sticky tape spigot surface 11 of this embodiment can laminate with sticky tape a's recovery face B when leading sticky tape a, and sticky tape spigot surface 11 is located the direction of keeping away from receipts material carousel 3 on the guide block 13 simultaneously, also retrieves face B towards the direction of receiving material carousel 3 promptly. Therefore, after the adhesive tape A is driven by the material receiving turntable 3 to slide out of the adhesive tape guide surface 11, the recovery surface B can be quickly peeled off from the adhesive tape A by the material receiving turntable 3, so as to ensure that the clamping part 1 is pulled to the non-recovery surface (shown as an area f in fig. 7) on the adhesive tape A of the cutting part 2.

Preferably, the position of the clamping portion 1 can be set below the feeding turntable 4 and the receiving turntable 3, and at this time, when the guide block 13 slides relative to the adhesive tape a (after the clamping portion 1 pulls the adhesive tape a to the cutting portion 2, the clamping block 12 and the guide block 13 release the clamping of the adhesive tape a, and at this time, the guide block 13 returns to the position before pulling), the adhesive tape guide surface 11 is always attached to the recovery surface B, so as to ensure that the adhesive tape a is consistently in a tightened state in the whole process.

Optionally, the moving mode of the clamping portion 1 in this embodiment can be realized by a slide rail and other mechanisms, so that the smoothness of movement is ensured, and the guide of the slide rail to the clamping portion 1 can also ensure the relatively stable movement stroke in the advancing process, so that the length of the adhesive tape for pulling and shearing the adhesive tape a is relatively fixed every time.

The adhesive tape cutting device of the embodiment utilizes the cooperation of the material receiving rotary disc 3 and the clamping part 1 to recover the recovery surface B, and further utilizes the cooperation of the clamping part 1 and the cutting part 2 to cut the adhesive tape A. Therefore, on one hand, the recycling surface B is convenient to effectively recycle, and the pollution to the working environment is avoided. On the other hand, the length of each cut adhesive tape A is relatively fixed, so that workers can conveniently wind the adhesive tape A, and the waste of the adhesive tape can be reduced. Meanwhile, the adhesive tape cutting device also saves the operation flow of manually tearing the recovery surface B and cutting the adhesive tape A, and greatly improves the working efficiency.

Further, the guide block 13 has a tape guide groove 131 facing the clamp block 12, and a bottom of the tape guide groove 131 is used to form at least a part of the tape guide surface 11. The depth and width of sticky tape guide way 131 in this embodiment can with the width and the thickness looks adaptation of sticky tape to guarantee that sticky tape A can be smooth and easy slide in sticky tape guide way 131, can also play the guide effect to sticky tape A simultaneously. The clamping block 12 in this embodiment is opposite to the clamping block 12, so as to ensure that the adhesive tape a can be tightly attached to the bottom of the adhesive tape guide groove 131 when the adhesive tape a is clamped.

Further, the clamping block 12 has a convex contact 121, the guide block 13 has a recess 132 disposed opposite to the convex contact 121, and the bottom of the recess 132 is used to form part of the tape guide surface 11. The convex contact 121 and the concave recess 132 cooperate to contact the adhesive tape a at the same time when clamped. In this embodiment, the recess 132 is located at the position of the tape guide groove 131 and has the same depth as the tape guide groove 131, so that the tape a can smoothly slide in the two.

Specifically, the cross section of the recess 132 in the present embodiment may be configured as a rectangle, and the cross section of the contact 121 may be configured as a circle having a diameter smaller than the short side of the rectangle, and the end of the contact 121 may be partially inserted into the recess 132 while avoiding interference when the tape a is clamped.

As shown in fig. 4, in some embodiments, the clamping block 12 further has a boss 122 disposed at a distance from the contact 121, and the height of the boss 122 is configured to be smaller than the height of the contact 121 to limit the clamping force to the adhesive tape a when the boss 122 abuts on the guide block 13. The height of the contact 121 is configured in this embodiment, so that when the clamping block 12 and the guiding block 13 clamp the tape a, the boss 122 contacts with the side wall of the guiding block 13, and the contact 121 keeps a distance from the bottom of the recess 132, but the distance is smaller than the thickness of the tape a. Thereby can guarantee the centre gripping to sticky tape A, still restricted the centre gripping dynamics at certain limit simultaneously.

As shown in fig. 3, in some embodiments, the nip portion further has an avoidance surface 14, and the avoidance surface 14 is used for avoiding the recovery surface B and forms an acute angle with the tape guide surface 11. In order to make the recovering surface B easier to peel off from the adhesive tape A, the angle between the recovering surface B and the advancing direction of the adhesive tape A can be adjusted, and when the included angle is larger than 90 (as shown in state III in FIG. 7), the adhesive tape A is easier to tear off. For this reason, the escape surface 14 in the present embodiment is disposed in such a manner that the recovery surface B does not interfere with the guide block 13.

As shown in fig. 3-4, in some embodiments, the clamp 1 also has a linear guide 15, a first linear actuator 16, a support bracket 18, and a second linear actuator 17. The guide block 13 is movably arranged on a linear guide 15, and the output shaft of a first linear drive 16 is connected with the clamping block 12. The support bracket 18 is used to fix the linear guide 15 and the first linear actuator 16. The second linear actuator 17 is fixed to the support frame 18 and is used to drive the first linear actuator 16, the guide block 13 and the clamping block 12 in a synchronous reciprocating motion. The second linear driver 17 in this embodiment can simultaneously drive the first linear driver 16, the guide block 13 and the clamping block 12 to move together, so as to complete the pulling of the adhesive tape a to the cutting part 2 and the resetting after the pulling. So that the guide block 13 and the clamping block 12 can simultaneously realize a movement in two mutually perpendicular directions.

As shown in fig. 1 to 8, in some embodiments, the tape cutting apparatus further includes at least one guide post 5 for guiding a conveying direction of the adhesive tape a. A guide post 5 is provided in the extending direction of the tape guide surface 11 opposite to the cutting hole 21 so that the conveying direction of the tape A is kept in agreement with the extending direction of the tape guide surface 11 before the tape A reaches the nip portion 1. The region h of state i of fig. 7 shows the guide post 5 for keeping the conveying direction in line with the extending direction of the tape guide surface 11. The guide post 5 can prevent the adhesive tape from being scratched by the edge of the guide block 13 before the adhesive tape is guided into the adhesive tape guide surface 11, and the smoothness of the transmission of the adhesive tape A is also improved.

Further, another guide post 5 is provided in a region between the nip 1 and the receiving turntable 3 so that the recovery surface B comes close to the escape surface 14 when peeled off. The area g of the state I in fig. 7 shows the guide post for adjusting the conveying direction of the recovery surface B and the adhesive tape A, and the guide post 5 can make the setting area of the material receiving turntable have various choices and keep the included angle between the recovery surface B and the adhesive tape A, thereby improving the tearing effect.

As shown in fig. 1 and 7, in some embodiments, the tape cutting apparatus further includes a tape position adjusting block 6 fixedly attached to the guide post 5, and a bottom of the tape position adjusting block 6 contacts the tape a for controlling a position of the tape a on the guide post 5. The tape position adjusting block 6 of the present embodiment allows the tape to be accurately fitted to a component part passing through during the transfer. The tape position adjusting block 6 shown in fig. 1 is provided on the guide post located in the area h in fig. 7 so as to cooperate with the guide post to guide the tape a in the height and horizontal directions simultaneously before it reaches the tape guide groove 131.

Further, the feed turntable 4 is provided with damping members for damping the rotational direction of the feed turntable 4. In order to keep the adhesive tape a in a taut state after being fed out from the feeding turntable 4, the embodiment uses the damping member to limit the rotation of the feeding turntable 4, so as to increase the tension of the feeding side of the adhesive tape.

As shown in fig. 1 to 7, in some embodiments, the tape cutting apparatus further includes a tension wheel 7 movably disposed in an area between the receiving turntable 3 and the nip 1 to adjust a tension of the recovery surface B. The state ii and the state iii in fig. 7 show two positions of the guiding block, in which the length of the recovering surface B between the guiding block 13 and the tensioning wheel 7 is changed, so that the tensioning force of the recovering surface B is continuously changed in use, and in order to compensate for the distance, the tensioning wheel 7 of the embodiment can move between the receiving turntable 3 and the clamping part 1 to compensate for the changed distance, so as to keep the tensioning force of the recovering surface B in the area relatively stable.

Alternatively, the position of the tension wheel 7 can be changed by a linear guide rail, and an elastic device such as a spring can be arranged at one end of the linear guide rail, the compression of the spring can make the tension wheel 7 have a space for moving when the tension force is increased, and the tension wheel can automatically reset when the tension force is reduced.

Further, the adhesive tape cutting device further comprises a material receiving driver 8, a material receiving sensor 9 and a controller 10 which is in communication connection with the material receiving driver 8 and the material receiving sensor 9. The output shaft of the material receiving driver 8 is connected with the rotating shaft of the material receiving rotary disc 3, and the material receiving sensor 9 is used for detecting the position of the tensioning wheel 7 to generate a position signal. The controller 10 is configured to adjust the rotational speed of the material receiving drive 8 depending on the position signal. When the tensioning force increases in this embodiment, directly reduce the rotational speed of receiving material carousel 3, reduced the speed of taking out of retrieving face B to prevent that the tensioning force from continuing to increase, vice versa. The embodiment further controls the tension through an electromechanical system to achieve a fast response to changes in tension.

As shown in fig. 3, in some embodiments, the cutting portion includes a holder 22 and a cutter 23, and the cutter 23 is movably disposed at a position opposite to the holder 22 to form the cutting hole 21. The present embodiment cuts the adhesive tape a torn off the recovery surface B by the cooperation of the cutter 23 and the cutter holder 22, thereby reducing the operating strength of the site worker.

Further, the first linear actuator 16 and the second linear actuator 17 in the above embodiment may be a first cylinder and a second cylinder, respectively. The cutter 23 may also be connected to the output shaft of the third cylinder. Each air cylinder can also be in communication connection with the controller 10 in the above embodiment, so that the tape cutting device can operate according to a predetermined program, so that the tape cutting device of the present embodiment can automatically complete the recovery and cutting of the adhesive tape a.

The tape cutting device of the above embodiment can be operated as follows. As shown in fig. 1-8, in some embodiments, the mode of operation may include three steps of tape clamping, device running, and device resetting.

In the apparatus operation steps (states ii, iii, and iv in fig. 7), the tape cutting apparatus is started and the plurality of air cylinders are controlled by the controller 10. Specifically, the controller 10 first controls the first cylinder to cause the clamp block 12 to clamp the adhesive tape a (arrow e in fig. 7). Then, the second cylinder is activated to push the gripped adhesive tape a to the cut portion 2 (arrow d in fig. 7). Meanwhile, the material receiving turntable 3 is always kept rotating in the process, and the recovery surface B is continuously pulled, so that the recovery surface B is stripped from the adhesive tape A. In this process, the recovery surface B is pulled, and therefore the tension pulley 7 moves to the left (arrow c in fig. 7) to compensate. And finally, starting a third air cylinder to pull the cutter 23 to cut the adhesive tape A.

In the device resetting step (state v in fig. 7), the first cylinder pulls the clamp block 12 away from the guide block 13, and the second cylinder pulls the clamp 1 to reset. In order to ensure that the adhesive tape A is always in a stretched state, the material receiving turntable 3 can keep a certain torque.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
