As shown in fig. 2, the present invention discloses a paper tape unwinding apparatus 10, including: a paper tape unwinding mechanism 20, a paper tape stretching and holding mechanism 30 and a paper tape punching mechanism 40. The paper tape unreeling device 10 of the present invention realizes unreeling, unfolding holding, and blanking of a paper tape 100. Through the processing of one set of paper tape unwinding equipment 10 realization paper tape 100's multichannel process, the mechanism between the multichannel process closely cooperates, promotes each other for paper tape 100 rationally passes between the multichannel process and optimizes each other, and then makes paper tape 100 machining efficiency high, effectual.
As shown in FIG. 1, paper strap 100 is a thin, flexible paper. Therefore, the paper strap 100 is generally packaged and stored by winding. When processing paper tape 100, paper tape 100 needs to be unwound first. The paper tape unwinding mechanism 20 (as shown in fig. 8) provided by the present invention unwinds the paper tape 100, and slips the paper tape 100 when punching the paper tape, so as to ensure that the paper tape 100 is accurately punched and prevent the paper tape 100 from breaking.
As shown in fig. 8, in the present invention, the tape unwinding mechanism 20 includes: a driving unreeler 210, a driven unreeler 220 and an unreeling driver 230. The driving unreeling device 210 is in driving connection with the unreeling driver 230, and the driven unreeling device 220 is matched with the driving unreeling device 210.
As shown in fig. 8, in particular, the driving unreeling device 210 includes a driving rotary wheel 211 and a driven matching wheel 212. The paper tape unwinding mechanism 20 further includes a supporting base 240, the driven matching wheel 212 is connected to the supporting base 240 through an elastic connection member 213, the driven matching wheel 212 is disposed opposite to the driving rotating wheel 211, and the driving rotating wheel 211 is drivingly connected to the unwinding driver 230. In this embodiment, the unwinding driver 230 is connected to the driving pulley 211 through a power output gear 214. In a preferred embodiment, the power take-off gear 214 is coupled to the drive pulley 211 via a rack 215. Specifically, the driven fitting wheel 212 is connected to the elastic member connection member 213 through the connection post 216.
As shown in fig. 8, in particular, the elastic connection 213 is a spring, and the number of the springs is two so that the stability of the slave engaging wheel 212 is better.
As shown in fig. 8, in detail, the tape unwinding mechanism 20 further includes a driving guide wheel 260 and a driven guide wheel 270, and the driving guide wheel 260 is disposed on the supporting seat 240. The active guide wheels 260 orient and stabilize the web 100 toward the web equal length slitting mechanism 50. The driven guide wheel 270 directionally positions and transfers and guides the paper tape 100 unwound from the driven unwinder 220, so that the paper tape punching mechanism 40 stably punches the paper tape 100.
As shown in fig. 8, in particular, the paper tape unwinding mechanism 20 further includes a support frame 280, the driven guide wheel 270 is disposed on the support frame 280, and the driven unwinding device 220 is disposed on the support frame 280.
Specifically, as shown in fig. 2 and 8, the paper tape punching mechanism 40 is disposed between the driving unreeler 210 and the driven unreeling device 220, and the paper tape 100 is punched by the paper tape punching mechanism 40 during unreeling of the paper tape 100.
The operation of the tape unwinding mechanism 20 is described below (please refer to fig. 2 and 8):
after being unwound from the driven unwinding device 220, the paper tape 100 passes through a gap between the driving rotating wheel 211 and the driven matching wheel 212, and at the moment, the driving rotating wheel 211 and the driven matching wheel 212 form a clamping posture for the paper tape 100;
the unreeling driver 230 drives the driving rotating wheel 211 to rotate, and when the driving rotating wheel 211 rotates, the driving rotating wheel 211 and the driven matching wheel 212 clamp and drive the paper tape 100 to move; in the process, the paper tape 100 is continuously unreeled from the driven unreeling device 220, so that the unreeling of the paper tape 100 is realized;
it should be noted that the paper tape punching mechanism 40 is disposed between the driving unreeling device 210 and the driven unreeling device 220, and the paper tape 100 is punched by the paper tape punching mechanism 40 in the unreeling process of the paper tape 100;
at the moment that the paper tape punching mechanism 40 punches the paper tape 100, the paper tape punching mechanism 40 applies a punching pressure to the paper tape 100, wherein the punching pressure is perpendicular to the unwinding direction of the paper tape 100, and the paper tape 100 tends to stop unwinding momentarily due to the punching pressure; in addition, since the driven engaging wheel 212 is connected to the supporting base 240 through the elastic connecting member 213, the gap between the driving pulley 211 and the driven engaging wheel 212 is elastic and non-fixed; therefore, although the unreeling driver 230 continuously drives the driving roller 211 to rotate, the driving roller 211 and the driven matching roller 212 do not drive the paper tape 100 to move any more; at this time, although the driving rotating wheel 211 keeps rotating, the driven matching wheel 212 stops rotating, and the paper tape 100 also stops moving, namely, the paper tape 100 slips; when the paper tape 100 slips, the friction force of the driving rotating wheel 211 and the driven matching wheel 212 on the paper tape 100 is greatly reduced, when the paper tape punching mechanism 40 punches the paper tape 100, the paper tape 100 stops moving for a short time to enable punched holes to be accurate, the phenomenon that the paper tape 100 is broken due to the fact that the punching pressure and the unreeling tension are in opposition to each other when the paper tape 100 punches the holes is effectively avoided, and the phenomenon that the paper tape 100 keeps moving at the moment of punching the paper tape 100 to enable the paper tape punching mechanism 40 to punch a long strip-shaped through groove instead of a point-shaped through hole on the paper tape 100 is also effectively avoided;
after the paper tape punching mechanism 40 completes one-time punching, the paper tape punching mechanism 40 leaves the paper tape 100, and at the moment, the paper tape punching mechanism 40 does not form punching pressure on the paper tape 100 any more, so that the driving rotating wheel 211 and the driven matching wheel 212 clamp the paper tape 100 again and drive the paper tape 100 to move; namely, the slipping phenomenon disappears at this time, and the paper tape 100 returns to the normal unwinding state;
namely, the paper tape 100 is continuously switched between the unwinding state and the slipping state, so that the unwinding and normal punching of the paper tape 100 are realized.
As shown in fig. 1, the paper tape 100 is a thin, flexible tape-like structure, so that the paper tape 100 is easily twisted or deflected during long-distance transportation during unwinding of the paper tape 100. If the paper tape 100 is twisted or deflected when the paper tape 100 is punched, the holes of the paper tape 100 may be displaced or the shape of the holes may not meet the requirement. Therefore, in order to ensure that the paper tape 100 does not twist or deflect when the paper tape 100 is punched, and ensure the accuracy of punching, the present invention provides a paper tape stretching holding mechanism 30. The paper tape stretching and holding mechanism 30 holds the stretched state of the unwound paper tape 100 to ensure that the paper tape 100 is punched in the stretched state, thereby ensuring the accuracy of punching.
As shown in fig. 2 and 8, in the present invention, the tape unwinding holding mechanism 30 is disposed between the driving unwinding unit 210 and the driven unwinding unit 220 of the tape unwinding mechanism 20.

As shown in fig. 6, in particular, the spreader holder 322 includes: the clamping device comprises a clamping support 323, an elastic clamping block 324 and a clamping matching piece 325, wherein the clamping support 323 is arranged on the supporting base plate 321, the elastic clamping block 324 is pivoted on the clamping support 323, and the clamping matching piece 325 is arranged on the clamping support 323.
As shown in fig. 6, in particular, the unfolding clamp 322 further includes an elastic abutting member 326, and the elastic abutting member 326 is disposed on the clamping support 323; the elastic supporting member 326 supports against the elastic clamping block 324, so that the elastic clamping block 324 is pressed against the clamping fitting member 325, and the elastic clamping block 324 and the clamping fitting member 325 form a clamping receiving groove 327. Both sides of the paper tape 100 (shown in fig. 1) are respectively accommodated in the clamping accommodating grooves 327, and the elastic clamping blocks 324 and the clamping mating members 325 form a clamping structure for the paper tape 100 accommodated in the clamping accommodating grooves 327. As shown in fig. 8, when the end of the clamping fitting member 325 with the arc-shaped guide surface 328 is provided with the arc-shaped guide surface 328, and the paper tape 100 enters the clamping receiving groove 327 from the end of the clamping fitting member 325 with the arc-shaped guide surface 328, the arc-shaped guide surface 328 has an avoiding and guiding function on the paper tape 100, so that the paper tape 100 can enter the clamping receiving groove 327 more smoothly, and the paper tape 100 can be prevented from being turned over and twisted when entering the clamping receiving groove 327, and the paper tape 100 can be kept in an unfolded state when entering the clamping receiving groove 327. As shown in fig. 7, in the present embodiment, the elastic support 326 is a spring.
As shown in fig. 5, in particular, the stretching holding assembly 320 further comprises a fine adjustment screw 330, and the fine adjustment screw 330 is in driving connection with the stretching gripper 322. The number of the fine adjustment screws 330 is two, and the two fine adjustment screws 330 correspond to the two unfolding holders 322 one by one.
As shown in fig. 6, specifically, the elastic abutting member 326 has an arc abutting portion 340, the arc abutting portion 340 abuts against the elastic clamping block 324, and the elastic abutting member 326 is disposed in an inclined manner relative to the elastic clamping block 324.
As shown in fig. 3, in particular, the paper tape unwinding holding mechanism 30 further includes a blanking support platform 350 disposed on the unwinding holding base 310. The number of the spreader holding assemblies 320 is two, and the two spreader holding assemblies 320 are respectively disposed at both sides of the blanking support table 350.
The operation of the tape stretching and holding mechanism 30 will be described below (please refer to fig. 3 to 7 together):
after being unwound from the driven unwinder 220 of the paper tape unwinding mechanism 20, the paper tape 100 enters the paper tape unwinding holding mechanism 30 in an unwinding state, and the paper tape unwinding holding mechanism 30 holds the paper tape 100 in the unwinding state;
the two stretching maintaining assemblies 320 are respectively arranged at two sides of the blanking support platform 350, and when the paper tape punching mechanism 40 punches the paper tape 100 on the blanking support platform 350, the stretching maintaining assemblies 320 at two sides of the blanking support platform 350 maintain the stretching state of the paper tape 100, so that the paper tape punching mechanism 40 precisely punches the paper tape 100, and the hole position of the paper tape 100 is ensured to be accurate;
it should be noted that, the stretching holding assembly 320 has two stretching holders 322, and the two stretching holders 322 are disposed oppositely, so that the holding grooves 327 of the stretching holders 322 are disposed oppositely and are respectively disposed on two sides of the paper tape 100, that is, the two holding grooves 327 receive two sides of the paper tape 100 and form holding structures for two sides of the paper tape 100, so that the paper tape 100 is held in a stretched state;
it should be noted that the elastic clamping block 324 is pivoted on the clamping support 323, and the elastic abutting member 326 abuts against the elastic clamping block 324, so that the elastic clamping block 324 is pressed on the clamping fitting member 325; this allows the resilient clamping block 324 to be resiliently clamped to the clamping engagement member 325; when the paper tape 100 initially enters the clamping receiving groove 327, in order to facilitate the entry of the paper tape 100, the elastic clamping block 324 may be pressed against one end of the clamping mating member 325 to be broken, so that the elastic clamping block 324 is separated from the clamping mating member 325, and at this time, the elastic clamping block 324 rotates along the clamping support 323 by an angle; after the paper tape 100 enters the clamping accommodation groove 327, the elastic clamping block 324 is released, and the elastic clamping block 324 is restored to a state of being pressed on the clamping fitting member 325 under the action of the elastic restoring force of the elastic abutting member 326, so as to form a clamping structure for the paper tape 100, and further keep the paper tape in a stretched state;
it should be noted that, since the elastic clamping block 324 is pivoted on the clamping support 323, and the elastic abutting member 326 abuts against the elastic clamping block 324, the elastic clamping block 324 is pressed against the clamping mating member 325; this allows the resilient clamping block 324 to be resiliently clamped to the clamping engagement member 325; thereby allowing the tape roll out retention mechanism 30 to be adapted to different thicknesses of the tape 100; the normal unwinding of the paper tape 100 is not influenced while the paper tape 100 is stretched and maintained;
it should be noted that the arc-shaped abutting portion 340 of the elastic abutting member 326 abuts against the elastic clamping block 324, and the elastic abutting member 326 is disposed obliquely relative to the elastic clamping block 324, so that the elastic abutting member 326 keeps abutting against the elastic clamping block 324, and the elastic clamping block 324 is not hindered from rotating along the clamping support 323, thereby ensuring that the paper tape stretching and retaining mechanism 30 works normally;
it should be further noted that the fine tuning screw 330 of the stretching holding assembly 320 is in driving connection with the stretching clamper 322, and the two fine tuning screws 330 correspond to the two stretching clampers 322 one by one; the position of the stretching clamp 322 is adjusted by fine-tuning the screw 330, so that on one hand, the distance between the two stretching clamps 322 can be adjusted, and thus the distance between the two clamping and accommodating grooves 327 can be adjusted, so that the stretching and holding assembly 320 can be suitable for stretching and holding paper tapes 100 with different widths, and thus the paper tape stretching and holding mechanism 30 can be suitable for paper tapes 100 with different widths, and the paper tape 1 stretching and holding mechanism 30 has strong adaptability and good flexibility; on the other hand, when the two stretching holders 322 are respectively adjusted in position in the same direction by the two fine adjustment screws 330, the position of the stretching holding assembly 320 is adjusted, so that the stretching holding assembly 320 drives the paper tape 100 to adjust in position, the punching position of the paper tape 100 is adjusted, and the adaptability and flexibility of the paper tape stretching holding mechanism 30 are further improved;
it should be noted that, in the present invention, the elastic clamping block 324 has an elongated structure, and the clamping engaging member 325 has an elongated structure, so that the stretching holding effect of the paper tape 100 is better.
As shown in fig. 2, in the present invention, the paper tape punching mechanism 40 is disposed above the paper tape stretching and holding mechanism 30, the paper tape 100 is stretched and held by the paper tape stretching and holding mechanism 30, and the paper tape punching mechanism 40 punches the paper tape 100 in a stretched state on the punching and supporting table 350 (shown in fig. 3), and the paper tape punching mechanism 40 and the paper tape stretching and holding mechanism 30 are tightly fitted, so that the punching effect of the paper tape 100 is good.
