Meanwhile, a shell 2 is arranged above the platform 9, a moving component 3 corresponding to the front side and the rear side of the raw material and a waste rejecting component 4 in transmission connection with the moving component 3 are arranged at the bottom of the shell 2, and a driving piece 5 for driving the shell 2 to move up and down relative to the platform 9 is fixedly arranged on the workbench 1. When the driving piece 5 is started to drive the shell 2, the moving component 3 and the reject component 4 to move towards the direction of the platform 9, the moving component 3 is attached to the front side and the rear side of the upper surface of the raw material, then the moving component 3 moves upwards relative to the shell 2 and drives the reject component 4 to rotate clockwise to correspond to defective parts on the raw material left and right, and then the winding roller 12 rotates to drive the raw material to move rightwards, so that the reject component 4 can automatically reject the defective parts.

In this embodiment, the raw material is rolled into a band shape, and the band shape is sleeved on the unreeling roller 11 and then detected by the detecting mechanism 10, the anti-counterfeit labels are arranged at equal intervals along the length direction of the band, and the front-back width dimension of the band is larger than the front-back width dimension of the anti-counterfeit labels. The starting piece can adopt a motor (not shown in the figure), the detection mechanism 10 can adopt the existing camera shooting detection mode, and meanwhile, a photoelectric sensor can be additionally arranged on the detection mechanism 10 to detect the distance between two adjacent anti-counterfeit labels, so that the detection range of the detection mechanism 10 is correspondingly adjusted, and the photoelectric sensor, the detection mechanism 10 and the starting piece of the winding roller 12 are all of the existing mature technology and are not described in detail herein.

Referring to fig. 1 to 4, in the present embodiment, it is preferable that: the moving assembly 3 comprises two supports 301 which are in up-down sliding fit with the bottom of the base and correspond to each other front and back, the supports 301 are of an inverted U-shaped design, rollers 302 are rotatably arranged in the supports, the two rollers 302 respectively correspond to the front side and the back side of the upper surface of the raw material in position, and the two rollers are in a dislocation state with the anti-counterfeit label. A first spring 304 is fixedly arranged between the top of the bracket 301 and the inside of the shell 2, the bracket 301 and the roller 302 have a trend of being away from the shell 2 downwards under the action of the first spring 304, a rack 303 in transmission connection with the waste picking assembly 4 is fixedly arranged on the right side surface of one bracket 301, and the waste picking assembly 4 can be driven to rotate clockwise through the rack 303 when the bracket 301 approaches to the shell 2.

Further, the waste rejecting assembly 4 comprises a vertical plate 401 fixedly connected with the bottom of the shell 2, a supporting rod 402 is rotatably arranged on the rear surface of the vertical plate 401, a gear 405 meshed with the rack 303 is fixedly arranged at the rear end of the supporting rod 402, the gear 405 is located above the rack 303, a cross rod 403 is fixedly arranged on the outer surface of the supporting rod 402, a rejecting block 404 is arranged at the end part, far away from the supporting rod 402, of the cross rod 403, and in order to guarantee the support of the rejecting block 404, the cross rod 403 is provided with two and front-back correspondence.

In the above structure, the entire rejecting block 404 is in an arc design, and a tip is disposed at one side of the rejecting block away from the cross bar 403, and when the rack 303 drives the gear 405 to rotate clockwise, the gear 405 drives the rejecting block 404 to rotate clockwise based on the support bar 402 through the support bar 402 and the cross bar 403, so that the tip of the rejecting block 404 abuts against the upper surface of the raw material.

Further, the driving member 5 may be a cylinder, and it is needless to say that an electric push rod, a conventional reciprocating screw, or the like may be used as long as the up-and-down reciprocating movement of the housing 2 is realized.

When in use, raw materials are pulled out from the unreeling roller 11, are guided to the top of the platform 9 after being detected by the detection mechanism 10, and are led out from the right side of the platform 9 and are recycled to the reeling roller 12. When the detecting mechanism 10 detects a defective part, the raw material continues to move to drive the defective part to move to the platform 9, then the cylinder drives the shell 2, the support 301, the roller 302, the support 402 and the rejecting block 404 to synchronously descend, and when the roller 302 contacts with the front side/rear side of the raw material, the roller 302, the support 301 and the rack 303 simultaneously contact with the top of the platform 9, at this time, the roller 302, the support 301 and the rack 303 rise relative to the shell 2 and squeeze the first spring 304, and the rack 303 drives the rejecting block 404 to rotate clockwise based on the support 402 through the gear 405, the support 402 and the cross bar 403, so that the rejecting block 404 contacts with the upper surface of the raw material and is in a state corresponding to the defective part (at this time, the rejecting block 404 is in a relatively tight fit state with the raw material). Then the raw materials continue to move to drive the defective parts to be in contact with the rejecting block 404, so that the rejecting block 404 rejects the defective parts from the raw materials, and the roller 302 can freely rotate in the process without influencing the movement of the raw materials; when the removing is completed, the rear cylinder drives the shell 2 and the vertical plate 401 to ascend, so that the rack 303 drives the gear 405 to reversely rotate in the ascending process of the shell 2, and then the support rod 402, the removing block 404 and the defective parts attached to the removing block 404 reversely rotate, so that interference is not caused to the continuous movement of the raw materials.

In summary, through the cooperation of the structures such as the roller 302, the gear 405, the supporting rod 402 and the rejecting block 404, when the defective part moves to the platform 9, the rejecting block 404 can be driven to rotate to correspond to the defective part left and right, and rapid rejection can be automatically realized along with continuous movement of the raw material, at this time, the rotation of the roller 302 does not influence the movement of the raw material and has a limiting effect on the raw material, forward and backward offset of the raw material when the defective part is rejected is avoided, and the buffer effect is also provided when the defective part descends to contact with the raw material, so that damage to the raw material can be effectively reduced, and meanwhile, the wrinkle of the raw material can be reduced and the damage can be reduced by the mode of left and right corresponding rejection. The whole operation utilizes the movement of the raw materials to realize automatic rejection, and the reject block 404 can drive the bad parts to reversely rotate and move away after the reject is finished, so that interference is not caused to the movement of the raw materials, and the whole reject process does not need to stop and the like until the raw materials are not moved, thereby avoiding the damage to the machine caused by repeated start-stop machine, effectively improving the whole working efficiency and having higher practicability.

Embodiment two:

referring to fig. 1 to 6, in order to ensure effective reject of defective parts, in the first embodiment, a rotary component 7 is disposed on the reject block 404, the cross bar 403 and the strut 402, and in an initial state, the rotary component 7 corresponds to a side of the surface of the reject block 404 away from the tip. Specifically, a round rod 305 is rotatably installed inside the bracket 301, a roller 302 is fixedly sleeved on the outer surface of the round rod 305 to form a rotary fit, the rear end of the round rod 305 extends to the outside of the bracket 301 and is fixedly provided with a worm wheel 306, and an adjusting assembly 6 in transmission connection with the worm wheel 306 and corresponding to the position of the rotating assembly 7 is jointly arranged between the bracket 301 and the housing 2.

When the roller 302 rotates, the round rod 305 drives the rotating assembly 7 to rotate anticlockwise through the adjusting assembly 6, so that the rotating assembly 7 corresponds to the tip end of the reject block 404 up and down, the right side of the reject block 404 is stably fixed on the reject block 404 by the rotating assembly 7 to avoid falling, and meanwhile, the adjusting assembly 6 drives the rotating assembly 7 to rotate with time delay, namely, the rotating assembly 7 does not rotate vertically when the roller 302 rotates, so that time is reserved for the contact between the reject block 404 and the reject block 404, and after the reject block 404 starts to start from the right side of the reject block 404, the rotating assembly 7 rotates again to realize the effective contact between the reject block 404 and the reject block 404.

Referring to fig. 1 to 8, in the present embodiment, it is preferable that: the adjusting component 6 comprises a connecting rod in running fit with the bottom of the shell 2, the connecting rod is divided into an upper section and a lower section, the upper section and the lower section are respectively a threaded section 602 and a worm section 601 in transmission connection with a worm wheel 306, and a sliding block 603 in sliding fit with the bracket 301 up and down and corresponding to the position of the rotating component 7 is sleeved on the outer surface of the threaded section 602. When the roller 302 starts to rotate, the round rod 305, the worm wheel 306 and the worm section 601 drive the threaded section 602 to synchronously rotate, so that the sliding block 603 vertically ascends relatively close to the shell 2 and contacts with the rotating assembly 7 during the ascending process.

Further, the rotating assembly 7 comprises a long rod 701 rotatably mounted on the rejecting block 404 and a convex rod 702 slidably engaged with the rod 402 and corresponding to the position of the slide 603, wherein the convex rod 702 can slide back and forth relative to the axial center of the rod 402, and a second spring (not shown) is fixedly mounted between the convex rod 702 and the rod 402, and the convex rod 702 has a tendency to slide outwards relative to the rod 402 under the action of the second spring. The outer surface of the long rod 701 is fixedly provided with a pressing plate 703, and when the pressing plate 703 rotates anticlockwise, the pressing plate 703 is matched with the tip of the rejecting block 404 up and down. The outer surface of the long rod 701 is fixedly wound with a pull rope 704 fixedly connected with the convex rod 702, and the pull rope 704 passes through the inner part of the corresponding cross rod 403, then enters the inner part of the supporting rod 402 and is fixedly connected with the convex rod 702. When the sliding block 603 contacts with the protruding rod 702, the protruding rod 702 is extruded to enable the protruding rod 702 to be relatively contracted into the supporting rod 402, release of the pull rope 704 is achieved, meanwhile, a torsion spring (not shown in the drawing) is sleeved on the outer surface of the long rod 701, the long rod 701 has a counterclockwise rotation trend under the action of the torsion spring, and therefore when the pull rope 704 is released, the long rod 701 can drive the pressing plate 703 to rotate counterclockwise under the action of the torsion spring.

In the above structure, in order to achieve good contact between the slider 603 and the boss 702, a rounded corner is formed at the top of the right side of the slider 603, which can contact with the boss 702 and push the boss 702 into the strut 402, and a certain vertical height difference exists between the slider 603 and the boss 702 in the initial state, so that the slider 603 cannot contact with the boss 702 immediately in the initial stage of lifting, and even if the reject block 404 has been rotated clockwise, a height difference exists between the slider 603 and the boss 702 in the vertical direction. Meanwhile, in order to realize automatic resetting of the sliding block 603 relative to the threaded section 602, so as to prepare for next defective piece rejection, a coil spring (not shown in the figure) is arranged on the outer surface of the round rod 305 or the outer surface of the connecting rod, so that when raw materials move towards the winding roller 12, the roller 302 is driven to rotate, the coil spring is stressed, and subsequently when the roller 302 is separated from the raw materials, the coil spring drives the worm wheel 306 and the connecting rod to rotate, so that the sliding block 603 automatically descends to realize resetting, and then the convex rod 702 and the pressing plate 703 realize resetting.

When the automatic rolling device is used, raw materials move from the unreeling roller 11, the detection mechanism 10 and the platform 9 to the wind-up roller 12, after the roller 302 is contacted with the raw materials, the rejecting block 404 is driven by the structures such as the rack 303 and the gear 405 to rotate clockwise based on the supporting rod 402, so that the rejecting block 404 is contacted with the upper surface of the raw materials and corresponds to defective parts left and right, and the rejecting block 404 of the defective parts is automatically realized along with the continuous right movement of the raw materials. The difference is that: when the roller 302 contacts with the raw materials and starts to rotate, the round rod 305 and the worm wheel 306 are driven to rotate, the worm wheel 306 drives the sliding block 603 to vertically ascend through the worm section 601 and the thread section 602, the sliding block 603 is not contacted with the convex rod 702 in the initial stage of ascending, and at the moment, the tip of the rejecting block 404 starts to contact with a defective part; the middle rising stage starts to contact with the convex rod 702 and enables the convex rod 702 to shrink inwards towards the supporting rod 402, the supporting rod 402 drives the pressing plate 703 to rotate anticlockwise through the structures of the pull rope 704, the long rod 701 and the like to form an up-down joint state with the tip of the rejecting block 404, at the moment, the part of the defective part above the tip of the rejecting block 404 is stably limited, and smooth separation of the defective part and raw materials can be ensured. Subsequently, when the roller 302 is separated from the raw material, the worm wheel 306, the worm section 601 and the thread section 602 can reversely rotate under the action of the coil spring, so that the sliding block 603 vertically slides down and returns to the original position, and accordingly reciprocates.

In the first embodiment, the reject block 404 is driven to rotate clockwise to correspond to the reject in left and right, and automatic reject is realized by using the movement of the raw material, but effective fixation cannot be formed between the reject and the tip of the reject block 404 in the reject process and after the reject and the raw material are completely separated, so that the reject may fall onto the raw material again after being separated from the reject block 404, which affects the collection of the reject and the rolling of the raw material, and has a certain use limitation.

Compared with the first embodiment, through the cooperation of the structures of the worm section 601, the convex rod 702, the sliding block 603, the pull rope 704 and the like, when the raw materials move, the roller 302 can be matched to form power transmission, so that the sliding block 603 vertically ascends to reduce the distance between the sliding block 603 and the convex rod 702 and form contact, and the position of the pressing plate 703 can be kept unchanged at the initial stage of the poor piece moving towards the rejecting block 404 along with the raw materials and the poor piece contacting with the rejecting block 404; when the defective piece is contacted with the upper surface of the rejecting block 404, the pressing plate 703 is in rotating fit with the rejecting block 404 to clamp the defective piece in the middle, so that the defective piece and the rejecting block 404 can be prevented from falling off, an auxiliary effect is provided for separating the defective piece from the raw material, stable collection of the defective piece is realized, and smooth rolling of the raw material is also ensured. The whole scheme utilizes the continuous movement of the raw materials, is combined with the rotation of the roller 302, cannot interfere the movement of the raw materials, reserves time for the contact of the defective parts and the rejection block 404, and has stronger applicability.

Embodiment III:

referring to fig. 1 to 9, in order to further ensure effective reject of defective parts, based on the second embodiment, a reject block 404 and a cross bar 403 are in sliding fit with each other through a sliding component 8, the reject block 404 can slide reciprocally relative to the length direction of the cross bar 403 based on the sliding component 8, and a lower support bar 604 corresponding to the position of the sliding component 8 is fixedly mounted on the right side of the sliding block 603.

Further, the lower abutment 604 is arranged in a front-back offset manner with respect to the protruding rod 702 of the rotating assembly 7, i.e. the lower abutment 604 does not interfere with the protruding rod 702 during the vertical lifting of the slide 603.

Referring to fig. 1 to 10, in the present embodiment, it is preferable that: the sliding assembly 8 comprises an L-shaped seat 801 fixedly connected with the rejecting block 404 and in sliding fit with the cross bar 403, the part of the L-shaped seat 801 protruding out of the cross bar 403 corresponds to the position of the lower supporting rod 604, when the sliding block 603 starts to contact with the protruding rod 702, the lower supporting rod 604 is just contacted with the protruding part of the L-shaped seat 801, and when the sliding block 603 starts to push the protruding rod 702 to retract inwards towards the supporting rod 402, the lower supporting rod 604 can enable the L-shaped seat 801 to ascend and drive the rejecting block 404 to synchronously move based on the cross bar 403. In order to achieve the resetting of the L-shaped seat 801, a third spring 802 is fixedly mounted between the surface of the L-shaped seat 801 and the cross bar 403, and the L-shaped seat 801 tends to move away from the strut 402 under the action of the third spring 802.

In the above structure, when the L-shaped seat 801 is lifted up based on the cross bar 403, the rejecting block 404 is driven to move synchronously, and the rejecting block 404 is driven to move synchronously with the pressing plate 703 and the long rod 701, although the long rod 701 pulls the pull rope 704 to a certain extent, the length of the pull rope 704 released by the protruding rod 702 when the protruding rod 702 is pressed by the sliding block 603 is enough.

When the device is in use, after the roller 302 contacts with the raw material, the rejecting block 404 is driven to rotate clockwise based on the supporting rod 402 through the structures such as the rack 303 and the gear 405, so that the rejecting block 404 contacts with the upper surface of the raw material and corresponds to the defective part left and right, the roller 302 starts to rotate along with the continuous movement of the raw material, and the right part of the defective part is pressed on the upper surface of the rejecting block 404 through the structures such as the convex rod 702, the sliding block 603 and the pull rope 704, and the working process and the effect of the part are the same as those of the second embodiment, and the repeated description is omitted. The difference is that: when the roller 302 rotates, the structure such as the worm wheel 306, the worm section 601 and the thread section 602 can drive the sliding block 603 and the lower supporting rod 604 to vertically ascend, the sliding block 603 is not contacted with the convex rod 702 at the initial stage of ascending, the lower supporting rod 604 is not contacted with the L-shaped seat 801, in the process, a defective part is contacted with the upper surface of the rejecting block 404, then the sliding block 603 is contacted with the convex rod 702, the lower supporting rod 604 is contacted with the L-shaped seat 801, the lower supporting rod 604 can drive the rejecting block 404 and the pressing plate 703 to ascend for a small distance through the L-shaped seat 801, and further the pressed part of the pressing plate 703 and the rejecting block 404 is driven to ascend for a small distance, so that the defective part can be separated from raw materials more easily.

In the second embodiment, the pressing plate 703 is driven to perform time-delay rotation to match with the rejecting block 404 to limit the right part of the defective part, so that the defective part can be separated from the raw material, but the defective part is always kept at a synchronous height with the raw material when separated from the raw material due to the fixing of the upper and lower positions of the rejecting block 404 and the pressing plate 703, so that the defective part is damaged by the folds, and part of defective parts can be continuously used after being repaired (removing the adhesive), the overall quality of the defective part damaged by the folds is reduced after being repaired, and the defective part cannot be put into use again, so that certain use limitations exist.

Compared with the second embodiment, through the cooperation of structures such as the sliding block 603, the lower supporting rod 604 and the L-shaped seat 801, when the sliding block 603 contacts with the convex rod 702 to enable the pressing plate 703 to rotate, the lower supporting rod 604 can be driven to contact with the L-shaped seat 801, so that the rejecting block 404 can move a small distance towards the direction of the supporting rod 402 relative to the cross rod 403, the bottom surface of the rejecting block 404 is further separated from the upper surface of the raw material, a height difference is formed between the right part of the defective part and the upper surface of the raw material, the defective part can be separated from the raw material more easily, meanwhile, the friction damage of the rejecting block 404 to the raw material can be reduced due to the separation of the defective part and the raw material, and the moving resistance of the raw material towards the winding roller 12 can be reduced. The whole scheme combines with the removal of slider 603 together, and bad piece right side rise and the mode of raw materials separation also accords with daily step of tearing the label more, and provides beneficial effect to the removal of raw materials, has satisfied more demands in the in-service use.
