[0011] The constant tension tape rewinder with controllable exit position provided by this invention has the following beneficial effects:

[0012] (1) The present invention is provided with a dual cleaning structure. The impurity cleaning fan in the dual cleaning structure rotates, and the impurity cleaning fan generates wind power through rotation. The wind power generated by the impurity cleaning fan is released on the tape during the rewinding process by the air collecting tube and the cleaning nozzle, which performs the first step of cleaning the tape. At the same time, the impurity cleaning bladder in the dual cleaning structure is also subjected to reciprocating compression, which generates airflow through reciprocating compression. The airflow is released on the tape through the impurity cleaning tube and the cleaning oblique hole, which performs the second step of cleaning the tape. In this way, in conjunction with the cleaning shaft A and the cleaning shaft B, the dust and impurities on the tape are cleaned, and the dust and impurities are prevented from being rewound along with the tape, which would reduce the quality of the tape after rewinding.

[0013] (2) The present invention is provided with a linkage operation structure. By setting the linkage operation structure, the power of the take-up shaft when rewinding the tape can be converted into the rotation power of the impurity cleaning fan and the power of squeezing the impurity cleaning bag. Thus, the power of the tape rewinding process is used to trigger the operation of the dual cleaning structure in the present invention. This can not only avoid impurities from affecting the tape rewinding, but also eliminate the need to provide dedicated power equipment for the tape cleaning work, effectively reducing the number of power equipment and lowering the manufacturing cost of the rewinding machine.

[0029] To make the objectives, solutions, and advantages of the technical solutions of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments of the present invention.

[0030] Please refer to Figures 1 to 10 As shown:

[0031] Example 1:

[0032] This invention provides a constant tension tape rewinding machine with controllable unwinding position, including a rewinding body 1, a control plate 2 disposed on the top left side of the rewinding body 1; a control groove 3 is provided on the control plate 2; a sliding post 4 is slidably installed inside the control groove 3; an unwinding shaft 5 is disposed on the front side of the sliding post 4; a control screw 6 is disposed on the control plate 2; the control screw 6 is connected to the sliding post 4 through threads; an operation button 7 is disposed on the top of the control screw 6; a cleaning plate 10 is disposed at the center of the top of the rewinding body 1; a connecting cross plate A8 is disposed between the left side of the cleaning plate 10 and the right side of the control plate 2.

[0033] The system includes a limiting shaft 9 on the front side of the connecting horizontal plate A8; a winding plate 32 on the top right side of the rewinding body 1; a connecting horizontal plate B17 between the left side of the winding plate 32 and the right side of the cleaning plate 10; a cleaning shaft B44 on the front side of the cleaning plate 10; a power shaft 11 on the rear side of the cleaning plate 10; a connecting synchronous pulley A12 at the rear end of the power shaft 11; an impurity cleaning fan 13 on the outer circumference of the power shaft 11; an air collecting duct 14 on the top front side of the cleaning plate 10; and the impurity cleaning fan 13 located inside the air collecting duct 14. The drive motor 36 drives the upper take-up shaft 33 to rotate, which in turn drives the connecting synchronous pulley D37 to rotate. Under the action of the synchronous belt, the connecting synchronous pulley D37 drives the connecting synchronous pulley A12 and the power shaft 11 to rotate. The rotation of the power shaft 11 drives the impurity cleaning fan 13 to rotate, which generates airflow and releases the airflow into the air collection duct 14. The air collection duct 14 then reduces the airflow and releases it onto the conveyor belt under the action of the cleaning nozzle 16, performing basic cleaning of the conveyor belt and preventing dust from affecting the subsequent rewinding of the conveyor belt.

[0034] Example 2:

[0035] This invention provides a constant tension tape rewinding machine with controllable unwinding position, and further includes a circulation hole 15 provided on the outer circumference of the air collecting duct 14; cleaning nozzles 16 arranged at equal intervals at the bottom of the air collecting duct 14; a slitting shaft 18 provided at the bottom front side of the connecting horizontal plate B17; a slitting blade 19 provided at the center of the slitting shaft 18; a cleaning shaft A20 also provided on the front side of the connecting horizontal plate B17; the cleaning shaft A20 is located above the slitting shaft 18; a connecting seat 21 is provided at the top of the connecting horizontal plate B17; a guide groove 22 is provided on the rear side of the connecting horizontal plate B17; a sliding plate 23 is slidably installed inside the guide groove 22; and an extrusion plate 24 is provided on the rear side of the sliding plate 23.

[0036] The extrusion disc 24 has a disc-shaped structure; one end of a restoring spring A25 is embedded in the top of the sliding plate 23; the other end of the restoring spring A25 is embedded in the top of the guide groove 22; a force transmission block 26 is centrally located at the bottom of the extrusion disc 24; the bottom of the force transmission block 26 has an inclined structure; a guide pipe 27 is provided on the connecting seat 21; the guide pipe 27 has an L-shaped structure; an impurity cleaning bag 28 is provided at the bottom end of the guide pipe 27; the impurity cleaning bag 28 is located above the extrusion disc 24; a connecting synchronous pulley B29 is provided on the slitting shaft 18; and an impurity cleaning pipe 3 is provided on the front side of the guide pipe 27. 0. The inclined surface of the trigger plate 41 pushes the inclined surface of the force transmission block 26, causing the force transmission block 26 to move upward along the guide groove 22 due to the pushing effect of the inclined surface. During the movement, the extrusion plate 24 pushes and squeezes the impurity cleaning bag 28, causing the impurity cleaning bag 28 to generate airflow due to the squeezing effect. The airflow enters the interior of the impurity cleaning pipe 30 under the action of the guide pipe 27. The impurity cleaning pipe 30 then releases the airflow onto the conveyor belt under the action of the cleaning inclined hole 31, performing secondary cleaning of impurities. This facilitates the thorough removal of impurities from the conveyor belt and improves the cleaning effect of impurities.

[0037] Example 3:

[0038] This invention provides a constant tension tape rewinding machine with controllable unwinding position, and further includes a cleaning oblique hole 31 on the left side of the impurity cleaning tube 30; the cleaning oblique hole 31 has an inclined structure; a take-up shaft 33 is provided on the take-up plate 32; a connecting synchronous pulley C34 is provided on the take-up shaft 33; the connecting synchronous pulley C34 and the connecting synchronous pulley B29 are connected by a synchronous belt; a mounting plate 35 is provided on the rear side of the take-up plate 32; the mounting plate 35 has a rectangular structure; a drive motor 36 is provided on the top of the mounting plate 35; the rear end of the upper take-up shaft 33 is connected to the output shaft of the drive motor 36; a connecting synchronous pulley D37 is provided on the upper take-up shaft 33; the connecting synchronous pulley D37 is connected to the connecting synchronous pulley A12 by a synchronous belt.

[0039] A transmission gear 38 is mounted on the lower take-up shaft 33; the transmission gear 38 is an incomplete gear; a follower rack 39 is slidably mounted on the rear side of the take-up plate 32; the follower rack 39 intermittently meshes with the transmission gear 38; a connecting plate 40 is mounted on the rear side of the follower rack 39; a trigger plate 41 is mounted on the connecting plate 40; the left end of the trigger plate 41 has an inclined structure; the inclined surface of the trigger plate 41 contacts the inclined surface of the force transmission block 26; an insert plate 42 is mounted on the right end of the follower rack 39; one end of a restoring spring B43 is embedded in the left side of the insert plate 42; the other end of the restoring spring B43 is embedded in the right side of the take-up plate 32. On the wall; a tape is wound and installed on the unwinding shaft 5, and the other end of the tape is successively bonded to the take-up shaft 33 via the limiting shaft 9, the cleaning shaft B44, and the cleaning shaft A20. When the take-up shaft 33 located below rotates, it drives the transmission gear 38 to rotate. Under the action of intermittent meshing with the follower rack 39, the transmission gear 38 drives the connecting plate 40 and the trigger plate 41 to move to the left. This makes it easier for the inclined surface of the trigger plate 41 to push against the inclined surface of the force transmission block 26, thereby converting the winding power of the take-up shaft 33 into a squeezing power, which is convenient for the subsequent squeezing of the impurity cleaning bag 28.

[0040] The specific usage and function of this embodiment are as follows: In use, first, one end of the tape is wound onto the unwinding shaft 5. Then, the other end of the tape passes sequentially through the limiting shaft 9, the cleaning shaft B44, and the cleaning shaft A20, and is finally attached to the take-up shaft 33. Then, by starting the drive motor 36, the drive motor 36 drives the upper take-up shaft 33 to rotate. This take-up shaft 33, under the action of the connecting synchronous pulleys C34 and B29, drives the lower take-up shaft 33 and the slitting shaft 18... The slitting blade 19 rotates, cutting the entire tape into two strips. Two take-up shafts 33 then rewind the two strips, achieving the slitting and rewinding of the tape. Simultaneously, the upper take-up shaft 33 drives the connecting synchronous pulley D37 to rotate. Under the action of the synchronous belt, the connecting synchronous pulley D37 drives the connecting synchronous pulley A12 and the drive shaft 11 to rotate. The drive shaft 11, through rotation, drives the impurity cleaning fan 13 to rotate, generating airflow and releasing the air. Inside the air collecting duct 14, the air collecting duct 14 reduces the airflow released onto the conveyor belt by the cleaning nozzle 16, performing basic cleaning of the conveyor belt and preventing dust from affecting the subsequent rewinding of the conveyor belt. At the same time, the winding shaft 33 below drives the transmission gear 38 to rotate. Under the action of the intermittent meshing of the transmission gear 38 with the follower rack 39, the connecting plate 40 and the trigger plate 41 move to the left. This allows the inclined surface of the trigger plate 41 to push against the inclined surface of the force transmission block 26. The force transmission block 26, under the influence of the inclined surface being pushed, drives the extrusion plate 24 and the sliding plate 23 to move upward along the guide groove 22. During the movement, the extrusion plate 24 pushes and squeezes the impurity cleaning bladder 28, causing the impurity cleaning bladder 28 to generate airflow under the influence of the extrusion. The airflow enters the interior of the impurity cleaning pipe 30 under the action of the guide pipe 27. The impurity cleaning pipe 30 then releases the airflow onto the conveyor belt under the action of the cleaning inclined hole 31, performing secondary cleaning of impurities, making it easier to thoroughly remove impurities from the conveyor belt and improving the cleaning effect of impurities.
