[0015] The beneficial effects of this application are mainly: 1. Wrap the tape with a protective layer around the No. 2 drive shaft in advance, and wrap one end of the tape around the bottom of the roller and extend it through the other side of the arc groove. Then install the fixed cover on the base. At this time, the fixed plate, telescopic motor and pressing plate are located in the roller. Start the telescopic motor to make the pressing plate squeeze the pressing plate, and then make the pressing plate drive the pressing mold installed on it to press the tape, so as to adjust the shape of the special-shaped tape.

[0016] 2. When the pressing shape of the special-shaped tape needs to be changed, start the No. 1 motor. Through the continuous engagement of the No. 1 gear and the No. 2 gear, the rotation of the No. 2 gear drives the mold assembly to rotate through the roller. By placing different mold assemblies under the pressing plate, the output of different special-shaped tapes can be achieved during the subsequent pressing action.

[0017] 3. During the pressing process, the pressing plate is mainly used to drive the pressing mold to press the tape. The displacement distance of the pressing plate is directly reflected by the pressing force of the pressing mold on the tape. The first distance sensor monitors the distance change of the pressing plate, which represents the pressing force of the pressing mold on the tape. It can adapt to different situations or the use of tapes of different thicknesses to ensure the pressing effect.

[0018] 4. The number of rotations and angles of gear No. 1 are consistent with those of the output end of motor No. 1. Since the number of teeth of gear No. 1 and gear No. 2 are in proportional relationship, the rotation angle of gear No. 2 can be known by knowing the number of teeth of gear No. 1 and the number of rotations and angle of gear No. 1. Therefore, by monitoring the number of rotations and angles of the output end of motor No. 1 through the first encoder, the rotation angle of gear No. 2 can be calculated, thereby realizing the adjustment of the positions of different mold components.

[0019] 5. The second encoder and the third encoder monitor the rotation speed of the output ends of the No. 2 motor and the No. 3 motor respectively. Since the No. 2 motor drives the transmission roller to rotate through the No. 1 drive shaft, the transmission roller will come into contact with the tape. As the transmission roller rotates, the friction between the transmission roller and the tape is used to realize the outflow of the tape. At the same time, the No. 3 motor drives the No. 2 drive shaft to rotate, thereby realizing the unwinding action of the tape wrapped on the No. 2 drive shaft. By monitoring and controlling the rotation speed of the output ends of the No. 2 motor and the No. 3 motor, the outflow speed of the tape is guaranteed.

[0020] 6. Since the tape will wrap around the surface of the No. 2 drive shaft, the distance between the No. 2 drive shaft and the inner wall of the placement cavity will be shortened. The second distance sensor can monitor the distance between the No. 2 drive shaft and the inner wall of the placement cavity to obtain the tape wrapping condition.

[0021] 7. The working conditions of motor No. 1, motor No. 2, motor No. 3, the first encoder, the second encoder, the third encoder, the first distance sensor and the second distance sensor will be transmitted to the controller, and the controller will synchronously transmit it to the display screen and the wireless communicator. The user can learn about the working conditions by observing the display screen, and the wireless communicator will display the received data through the display, thereby achieving the effect of remote monitoring.

The pressing plate 204 is detachably connected to a pressing mold on the side facing the arc groove 101, and there is a distance gap between the second gear 200 and the roller 201 and the arc groove 101. The mold assembly 2 07 is multiple in number, and the multiple pressing molds have different shapes; a fixed cover 300, the fixed cover 300 is detachably connected to the base 100, a fixed plate 301 is provided on the surface of the fixed cover 300, the fixed plate 301 extends to the inner cavity of the drum 201, a telescopic motor 302 is provided at the bottom of the fixed plate 301, a pressing plate 303 is provided at the output end of the telescopic motor 302, the bottom of the pressing plate 303 can be abutted against the surface of the pressing plate 204, and the telescopic motor 302 is electrically connected to the controller 106.

[0031] In this embodiment, the glue is arranged on the arc groove, and one end of the tape is extended out of the arc groove, and then the second gear drives the roller 201 and the mold assembly 207 to be placed on the arc groove, the second gear is located between the limit plates 120, and the second gear and the first gear are in a meshing relationship, and the fixed cover 300 is installed on the base 100.

The rotation of the second gear 200 drives the mold assembly 207 to rotate through the roller 201, and the pressing plates 204 of different mold assemblies 207 are placed under the pressing plate 303 to achieve the output of different shaped tapes during the subsequent pressing action; it should be noted that the fixed cover 300 and the base 100 are detachably connected by bolts, locks and other structures, and the detachable connection between the pressing plate 204 and the pressing mold is mainly achieved by providing a card slot matching the pressing mold on the pressing plate 204, and providing a compression pad and other structures in the card slot, and squeezing the pressing mold inserted into the card slot to achieve a detachable connection, so as to facilitate the subsequent replacement of the pressing mold and the difficulty of cleaning and disinfection; a cutting knife 121 can be provided on the top of the base 100 and on the side where the tape flows out. When the tape flows out, the user presses down the tape and cuts the tape through the cutting knife 121 to meet the user's needs.

[0032] See also Figure 1 , Figure 3 , Figure 5 and Figure 6 In some embodiments, a transmission cavity 107 is opened inside the base 100, and the transmission cavity 107 is connected to the arc-shaped groove 101. A No. 2 motor 108 is arranged inside the base 100, and the output end of the No. 2 motor 108 is connected to a No. 1 driving shaft 109, and the other end of the No. 1 driving shaft 109 is movably connected to the inner wall of the transmission cavity 107. A transmission roller 110 is arranged on the surface of the No. 1 driving shaft 109, and the surface of the transmission roller 110 extends to the inside of the arc-shaped groove 101.

[0033] In this embodiment, the second motor 108 rotates the transmission roller 110 through the first drive shaft 109, wherein the transmission roller 110 will come into contact with the tape. When the transmission roller 110 rotates, the tape will flow out under the action of friction. The transmission roller 110 is provided with anti-slip grooves or anti-slip particles and other structures to increase friction, thereby ensuring the stable flow of the tape.

[0034] See also Figure 1 , Figure 2 , Figure 3 , Figure 5 and Fig. 9 In some embodiments, a placement cavity 111 and a limiting groove 112 are provided inside the base 100, and the arc grooves of the limiting groove 112 are all connected to the placement cavity 111.

[0035] In this embodiment, after one end of the tape is fixed to the No. 2 drive shaft 114, the No. 3 motor 113 is started to rotate the drive shaft, thereby causing the tape to be rolled up onto the No. 2 drive shaft 114. During this process, the tape is squeezed through the clamping plate 116 under the action of the rebound force of the extrusion spring 115, thereby limiting the position of the tape. When the No. 3 motor 113 causes the No. 2 drive shaft 114 to rotate in the opposite direction, the tape is unrolled.

[0036] See also Figure 1 , Figure 8 and Fig.10 In some embodiments, a first distance sensor is disposed inside the fixing plate 301 . The first distance sensor is used to monitor the distance change of the pressing plate 204 . The first distance sensor is electrically connected to the controller 106 .

[0037] In this embodiment, during the pressing process, the pressing plate 204 is mainly used to drive the pressing mold to press the tape. The displacement distance of the pressing plate 204 is directly reflected as the pressing force of the pressing mold on the tape. The first distance sensor monitors the distance change of the pressing plate 204, which represents the pressing force of the pressing mold on the tape. It can adapt to different situations or the use of tapes of different thicknesses to ensure the pressing effect.

The surface teeth of the No. 1 gear 105 and the No. 2 gear 200 are in proportional relationship, and the first encoder is electrically connected to the controller 106.

[0039] In this embodiment, the number of rotations and angles of the output end of the No. 1 gear 105 and the No. 1 motor 104 are consistent. Since the number of teeth of the No. 1 gear 105 and the No. 2 gear 200 are in proportional relationship, the rotation angle of the No. 2 gear 200 can be known by knowing the number of teeth of the No. 1 gear 105 and the number of rotations and angle of the No. 1 gear 105. Therefore, by monitoring the number of rotations and angles of the output end of the No. 1 motor 104 through the first encoder, the rotation angle of the No. 2 gear 200 can be calculated, and the position of different mold assemblies 207 can be adjusted.

[0040] See also Figure 1 , Figure 2 , Figure 3 , Figure 6 and Fig.10 In some embodiments, a second encoder is disposed on the surface of the second motor 108, and a third encoder is disposed on the surface of the third motor 113.

[0041] In this embodiment, the second encoder and the third encoder monitor the rotation speed of the output ends of the No. 2 motor 108 and the No. 3 motor 113 respectively. Since the No. 2 motor 108 drives the transmission roller 110 to rotate through the No. 1 drive shaft 109, the transmission roller 110 will come into contact with the tape. As the transmission roller 110 rotates, the friction between the transmission roller 110 and the tape is used to realize the outflow of the tape. At the same time, the No. 3 motor 113 drives the No. 2 drive shaft 114 to rotate, thereby realizing the unwinding action of the tape wrapped on the No. 2 drive shaft 114. By monitoring and controlling the rotation speed of the output ends of the No. 2 motor 108 and the No. 3 motor 113, the outflow speed of the tape is guaranteed.

The second distance sensor is electrically connected to the controller 106 .

[0043] In this embodiment, since the tape will be wrapped around the surface of the No. 2 drive shaft 114, the distance between the No. 2 drive shaft 114 and the inner wall of the placement cavity 111 will be shortened. The second distance sensor monitors the distance between the No. 2 drive shaft 114 and the inner wall of the placement cavity 111 to obtain the tape wrapping condition.

At this time, the fixed plate 301, the telescopic motor 302 and the pressing plate 303 are located in the roller 201; The telescopic motor 302 is started to make the pressing plate 303 squeeze the pressing plate 204, and then the pressing plate 204 drives the pressing mold installed thereon to press the tape, so as to adjust the shape of the tape. Since the pressing molds on different mold assemblies 207 have different shapes to adapt to the pressing of different shapes of special-shaped tapes, when the pressing shape of the special-shaped tape needs to be changed, the No. 1 motor 104 is started, and the No. 1 gear 105 and the No. 2 gear 200 are continuously engaged, and the No. 2 gear 200 rotates and then drives the mold assembly 207 to rotate through the roller 201. By placing the pressing plates 204 of different mold assemblies 207 under the pressing plate 303, the output of different special-shaped tapes during the subsequent pressing action can be achieved; When the tape flows out, the second motor 108 and the third motor 113 work at the same time, thereby rotating the first drive shaft 109 and the second drive shaft 114. When the second drive shaft 114 rotates in the opposite direction, the tape is unwound, and the transmission roller 110 is used to achieve the tape outflow effect under the action of friction during the rotation process. The speed of the output end of the second motor 108 and the third motor 113 is monitored and controlled to ensure the tape outflow speed. The first distance sensor monitors the distance change of the pressing plate 204 to represent the pressing force of the pressing mold on the adhesive tape, so as to adapt to different situations or the use of adhesive tapes of different thicknesses; By monitoring the rotation number and angle of the output end of the No. 1 motor 104 through the first encoder, the rotation angle of the No. 2 gear 200 can be calculated, and the position of different mold assemblies 207 can be adjusted; The second distance sensor monitors the distance between the second drive shaft 114 and the inner wall of the placement cavity 111 to obtain the tape winding condition; The working conditions of motor No. 104, motor No. 208, motor No. 313, the first encoder, the second encoder, the third encoder, the first distance sensor and the second distance sensor are transmitted to the controller 106, and the controller 106 synchronously transmits the data to the display screen 117 and the wireless communicator. The user can learn about the working conditions by observing the display screen 117, and the wireless communicator displays the received data through the display, thereby achieving a remote monitoring effect.
