[0012] 1. The present invention is provided with a release unit. When the anti-pinch rubber strip on one roller is completely released and replaced with another roller, the release and discharge of the anti-pinch rubber strip is facilitated. When producing the anti-pinch rubber strip for the revolving door, one end of the anti-pinch rubber strip on the roller is pulled out, and the roller is rotated by the release unit. After the anti-pinch rubber strip on one roller is completely released, the motor 5 rotates the connecting block 5 and replaces it with another roller.

In the stage of the releasing unit releasing the anti-pinch rubber strips, the released roller is conducive to winding the anti-pinch rubber strips that have not been sorted. Through the releasing unit, when releasing the anti-pinch rubber strips, it is convenient to wind the anti-pinch rubber strips that have not been sorted through another roller, and the frequency of the roller releasing the anti-pinch rubber strips is the same as the frequency of the other roller winding the new anti-pinch rubber strips. After the anti-pinch rubber strips on the roller are released, the two rollers are rotated to replace the operation, thereby avoiding unnecessary waste of material resources in the roller replacement stage.

[0013] 2. The present invention is provided with a replacement unit, and the replacement unit is based on the remaining part of the anti-pinch rubber strip on the roller. The replacement unit determines the timing of replacing the roller according to the remaining part of the anti-pinch rubber strip. After the anti-pinch rubber strip on one roller is released, the motor 5 is used to rotate the connecting block 5, so that the linkage block 5 is rotated, and the pressing plate presses the cross block and the threaded beryllium copper wire 5, so that the cross block presses the cutting blade 5 downward into the receiving block to cut the anti-pinch rubber strip in the receiving block. After the cutting blade 5 cuts off the anti-pinch rubber strip, the pressing plate is released from the cross block, and the pressing plate is then rotated, and the other rollers are connected with the other releasing rollers. The units are connected, the horizontal block is pressed and moved upward, and the anti-pinch rubber strip in the connecting block 6 is cut after connecting with the cutting blade 6, and the connection with the horizontal block is released and the horizontal block returns to its original state. The anti-pinch rubber strips on the two rollers are released from the connection with the outside. With the positive rotation of the connecting block 5, the circle block 8 of the other roller is engaged and rotated with the linkage block 6 on the supporting seat. The circle block 8 makes the circle block 5 rotate, and the anti-pinch rubber strip is pulled out from the roller through the circle block 5. After the connecting block 5 rotates a flat angle, the pulled anti-pinch rubber strip falls into the receiving block and is pulled to the outside through the conveyor belt, which is convenient for replacing the rollers. After the drum is wound, there is no need to connect the anti-pinch rubber strip, and one end of the anti-pinch rubber strip is extended out of the connecting block six and a pair of circle blocks five, and is fixedly connected to the drum waiting to be wound, and the circle block seven is rotated by the motor six to release the anti-pinch rubber strip. At this stage, the unsorted anti-pinch rubber strip is wound through the circle block six, so that the release and winding of the anti-pinch rubber strip are carried out at the same time, and the two have the same frequency, which is conducive to maintaining the release and replenishment of the anti-pinch rubber strip at the same time, ensuring the efficient production of the anti-pinch rubber strip. After the anti-pinch rubber strip on the drum at one end of the circle block seven is released, the connecting lever five and the connecting lever six follow the anti-pinch rubber strip. The distance between them is shortened, and the threaded beryllium copper wire 6 and the threaded beryllium copper wire 7 are moved toward the roller through the elasticity, until the push block 5 at one end of the connecting rod 5 is in contact with the opening and closing button 5, and the opening and closing button 5 makes the motor 5 rotate forward by a right angle to replace the roller. When the anti-pinch rubber strip on the roller at the end of the ring block 7 is wound more, the connecting rod 6 stretches the threaded beryllium copper wire 7 and moves in the supporting mouth 5, until the push block 6 at the end of the connecting rod 6 is in contact with the opening and closing button 6, the motor 5 is rotated forward by a right angle to replace the roller, so as to replace the two rollers according to the increase or decrease of the anti-pinch rubber strip on the roller.

[0014] 3. The present invention is provided with a receiving block, a roller, a fifth connecting rod and a sixth connecting rod. The smooth receiving block is beneficial to reducing the resistance between the anti-pinch rubber strip and the receiving block when one end of the anti-pinch rubber strip moves along the receiving block, so as to facilitate the traction and release of the anti-pinch rubber strip, so that the anti-pinch rubber strip can be attached to, pulled and released by the conveyor belt through the receiving block. The smooth roller is beneficial to protecting the side wall of the anti-pinch rubber strip when in use, and the resistance of the side wall of the fifth connecting rod and the sixth connecting rod is increased through the leather cover, so as to facilitate the rotation of the fifth connecting rod and the sixth connecting rod along the anti-pinch rubber strip on the roller.

[0027] After the anti-pinch rubber strip on one roller 8 is completely released, the motor 53 causes the connecting block 54 to rotate, causing the linkage block 59 to rotate, and the pressing plate 21 presses the cross block 22 and the threaded beryllium copper wire 5 24, causing the cross block 22 to press the cutting blade 5 26 downward to the receiving block 5 to cut the anti-pinch rubber strip in the receiving block 5. After the cutting blade 5 26 cuts off the anti-pinch rubber strip, the pressing plate 21 is disconnected from the cross block 22, and the pressing plate 21 is then rotated, and the other roller 8 is connected to the other release unit, pressing the cross block 22 to move upward, and the anti-pinch rubber strip in the connecting block 6 27 is cut after connecting with the cutting blade 6, and the connection with the cross block 22 is released, and the cross block 22 returns to its original state, and the anti-pinch rubber strips on the two rollers 8 are disconnected from the outside. With the positive rotation of the connecting block 54, the ring block 810 of the other roller 8 is connected to the supporting seat 2 The upper linkage block six 31 interlocks and rotates, and the circle block eight 210 causes the circle block five 10 to rotate, and the anti-pinch rubber strip is pulled out from the roller 8 through the circle block five 10. After the connecting block five 4 rotates a flat angle, the pulled anti-pinch rubber strip falls into the receiving block 5 and is pulled to the outside through the conveyor belt 6, which is beneficial for replacing the roller 8 without docking the anti-pinch rubber strip. One end of the anti-pinch rubber strip is extended out of the connecting block six 27 and a pair of circle blocks five 10, and is fixedly connected to the roller 8 waiting to be wound, and the circle block seven 29 is rotated by the motor six 33 to release the anti-pinch rubber strip. At this stage, the unsorted anti-pinch rubber strip is wound through the circle block six 28, so that the release and winding of the anti-pinch rubber strip are carried out simultaneously, and the two have the same frequency, which is beneficial to maintaining the release and replenishment of the anti-pinch rubber strip at the same time, ensuring the efficient production of the anti-pinch rubber strip.

[0028] The replacement unit includes a support port 5 37 and a support port 6 41, which are respectively mounted at the two ends of the drum 8, and one end of the support port 5 37 and the support port 6 41 are respectively connected to the connecting block 5 4, and a connecting rod 5 32 is mounted on the support port 6 41, and one end of the connecting rod 5 32 is movably mounted in the support port 6 41, and a threaded beryllium copper wire 6 35 is fixedly connected to the support port 6 41, and the lower end of the support port 6 41 is fixedly connected to the opening and closing button 5 36, and the lower end of the connecting rod 5 32 is fixed. The push piece 5 34 is connected, and the push piece 5 34 can be attached to the opening and closing button 5 36; a connecting rod 6 310 is installed on the support mouth 5 37, and one end of the connecting rod 6 310 can be movably installed in the support mouth 5 37, and the support mouth 5 37 is fixedly connected to the threaded beryllium copper wire 7 38, and the lower end of the support mouth 5 37 is fixedly connected to the opening and closing button 6 39, and the lower end of the connecting rod 6 310 is fixedly connected to the push piece 6, and the push piece 6 can be attached to the connecting rod 6 310, and the opening and closing button 5 36 and the opening and closing button 6 39 are respectively electrically connected to the motor 5 3;

[0029] After the anti-pinch rubber strip on the roller 8 at one end of the ring block 729 is completely released, the distance between the connecting rod 5 32 and the connecting rod 6 310 shortens as the anti-pinch rubber strip decreases, and the connecting rod 5 and the connecting rod 6 310 move toward the roller 8 through the elasticity of the threaded beryllium copper wire 6 35 and the threaded beryllium copper wire 7 38, until the push block 5 34 at one end of the connecting rod 5 32 touches the opening and closing button 5 36, and the opening and closing button 5 36 causes the motor 5 3 to rotate forward by a right angle to replace the roller 8. When the anti-pinch rubber strip on the roller 8 at one end of the ring block 729 is wound more, the connecting rod 6 310 stretches the threaded beryllium copper wire 7 38 and moves in the supporting port 5 37, and when the push block 6 at one end of the connecting rod 6 310 touches the opening and closing button 6 39, the motor 5 3 rotates forward by a right angle to replace the roller 8, which is convenient for replacing the two rollers 8 according to the increase or decrease of the anti-pinch rubber strip on the roller 8.

[0030] The upper wall surface of the receiving block 5 is a smooth surface, and the lower end of the cutting blade 5 26 can be in tight contact with the upper wall surface of the receiving block 5;

[0031] The smooth receiving block 5 is beneficial to reducing the resistance between the anti-pinch rubber strip and the receiving block 5 when one end of the anti-pinch rubber strip moves along the receiving block 5, thereby facilitating the traction and release of the anti-pinch rubber strip, so that the anti-pinch rubber strip can be attached, pulled and released to the conveyor belt 6 through the receiving block 5.

[0032] The side walls of the two rollers 8 are smooth surfaces;

[0033] The smooth roller 8 is beneficial to protecting the side wall surface of the anti-pinching rubber strip when in use.

[0034] The side walls of the connecting rod 5 32 and the connecting rod 6 310 are respectively fixedly connected to leather covers with high resistance.

[0035] The resistance of the side walls of the connecting rod 5 32 and the connecting rod 6 310 is increased through the leather cover, which facilitates the connecting rod 5 32 and the connecting rod 6 310 to rotate along the anti-pinching rubber strip on the drum 8.

[0036] The specific implementation method is as follows: during operation, in the stage of producing anti-pinch rubber strips for revolving doors, one end of the anti-pinch rubber strip on the roller 8 is pulled out, and the roller 8 is rotated through the releasing unit. After the anti-pinch rubber strip on one roller 8 is completely released, the connecting block 54 is rotated and replaced to another roller 8 through the motor 53. In the stage when the connecting block 54 rotates the two rollers 8, the releasing unit is conducive to cutting the wound or released anti-pinch rubber strip, so that the released anti-pinch rubber strip is replaced with the wound anti-pinch rubber strip, which is conducive to timely replenishing new anti-pinch rubber strips for the roller 8 that has released the anti-pinch rubber strips, and is conducive to sorting the anti-pinch rubber strips that have not been wound. In the stage when the releasing unit releases the anti-pinch rubber strips, the released roller 8 is convenient for winding the anti-pinch rubber strips that have not been sorted, and the releasing unit is conducive to the release of the anti-pinch rubber strips. The unit, when releasing the anti-pinch rubber strip, is convenient for winding the unsorted anti-pinch rubber strip through another roller 8, and the frequency of the roller 8 releasing the anti-pinch rubber strip is the same as the frequency of the other roller 8 winding the new anti-pinch rubber strip. After the anti-pinch rubber strip on the roller 8 is completely released, the two rollers 8 are rotated to replace the working state, thereby avoiding unnecessary waste of material resources in the stage of replacing the rollers 8. After the anti-pinch rubber strip on one roller 8 is completely released, the motor 53 is used to rotate the connecting block 54, so that the linkage block 59 is rotated, and the pressing plate 21 presses the cross block 22 and the threaded beryllium copper wire 5 24, so that the cross block 22 presses the cutting blade 5 26 downward to the receiving block 5 to cut the anti-pinch rubber strip in the receiving block 5. After the cutting blade 5 26 cuts off the anti-pinch rubber strip, the pressing plate 21 is released from the cross block 22, and the pressing plate 21 is connected As the connecting block 54 rotates in the forward direction, the circle block 8 210 of the other roller 8 engages with the linkage block 6 31 on the supporting seat 2 and rotates. The circle block 8 210 causes the circle block 5 10 to rotate, and the anti-pinch rubber strip is pulled out of the roller 8 through the circle block 5 10. After the connecting block 54 rotates a flat angle, the pulled anti-pinch rubber strip falls into the receiving block 5 and is pulled to the outside through the conveyor belt 6, which is beneficial for pulling one end of the anti-pinch rubber strip out of the roller 8 without docking the anti-pinch rubber strip after replacing the roller 8. The connecting block 6 27 and a pair of circle blocks 5 10 are extended out and fixedly connected to the roller 8 waiting to be wound. The circle block 7 29 is rotated by the motor 6 33 to release the anti-pinch rubber strip. In this stage, the circle block 6 28 is used to wind the unsorted anti-pinch rubber strip, so that the release and winding of the anti-pinch rubber strip are carried out simultaneously. The two have the same frequency, which is conducive to maintaining the release and replenishment of the anti-pinch rubber strip at the same time, ensuring the efficient production of the anti-pinch rubber strip. After the anti-pinch rubber strip on the roller 8 at one end of the circle block 7 29 is released, the connecting rod 5 32 and the connecting rod 6 310 are shortened in distance with the decrease of the anti-pinch rubber strip, and move closer to the roller 8 through the elasticity of the threaded beryllium copper wire 6 35 and the threaded beryllium copper wire 7 38, until the push block 5 34 at one end of the connecting rod 5 32 is in contact with the opening and closing button 5 36.After the opening and closing button 536 rotates the motor 53 in the forward direction by a flat angle, the roller 8 is replaced. When the anti-pinch rubber strip on the roller 8 at the end of the ring block 729 is wound more, the connecting rod 6310 stretches the threaded beryllium copper wire 738 and moves in the support port 537. After the pressing block 6 at one end of the connecting rod 6310 is in contact with the opening and closing button 639, the motor 53 rotates in the forward direction by a flat angle to replace the roller 8, which is conducive to replacing two rollers 8 according to the increase or decrease of the anti-pinch rubber strip on the roller 8.
