[0028] The technical solutions of the present invention will be further described in detail below with reference to the drawings and embodiments.

[0029] The present invention provides a strip positioning and aligning device. Through a series of mechanical actions, when the strip is conveyed to a certain position, the stop gauge starts to act to block the strip, and then the movable component also acts to align the strip left and right, greatly improving the cutting accuracy of the notebook. At the same time, after passing through this device, the strip will no longer rush forward, improving the production efficiency. As Figures 1 to 4 shown, in which a preferred embodiment of the present invention is shown.

[0030] As Figure 1 shown, the strip positioning and aligning device of the present invention includes: a frame, a cam transmission shaft 1 rotatably provided on the frame, a power mechanism connected to the cam transmission shaft 1, and a stop gauge positioning mechanism 2 and a side alignment mechanism 3 respectively connected to the cam transmission shaft 1.

[0031] As Figure 2 shown, the stop gauge positioning mechanism 2 includes a stop gauge cam 201 provided on the cam transmission shaft 1, a first swing arm fixed shaft 202 rotatably provided at the lower part of the frame, a first swing rod 203 provided between the stop gauge cam 201 and the first swing arm fixed shaft 202, a second swing rod 204 fixed on the first swing arm fixed shaft 202, a stop gauge mounting rod 207 rotatably provided at the upper part of the frame, a third swing rod 206 fixed on the stop gauge mounting rod 207, and a first joint pull rod 205 with two ends respectively connected to the second swing rod 204 and the third swing rod 206. A stop gauge 208 is further provided on the stop gauge mounting rod 207, and the stop gauge 208 swings under the pulling of the third swing rod 206.

[0032] Preferably, the stop gauge cam 201 is fixed in the middle of the cam transmission shaft 1, the second swing rod 204 is fixed at one end of the first swing arm fixed shaft 202, and the stop gauge mounting rod 207 is provided outside the frame. As Figure 3 shown, both ends of the stop gauge mounting rod 207 are cylindrical, the middle section of the stop gauge mounting rod 207 is prismatic, and the stop gauge 208 is fixed on the middle section of the stop gauge mounting rod 207. The stop gauge 208 is more stable when installed on the prismatic body and is suitable for paper slapping.

[0033] The cam transmission shaft 1 is connected to the power mechanism and is driven by the power mechanism to rotate. During the conveying process of the strip, the cam transmission shaft 1 rotates, and the stop gauge cam 201 fixed on the cam transmission shaft 1 also rotates simultaneously. Since the outer shape of the stop gauge cam 201 is a smooth curve with high and low points, as the stop gauge cam 201 rotates, the stop gauge cam 201 drives the first swing rod 203 to swing.

[0034] Moreover, since the first swing rod 203 is fixedly installed on the first swing arm fixed shaft 202, the first swing rod 203 drives the first swing arm fixed shaft 202 to rotate back and forth; the first swing arm fixed shaft 202 drives the second swing rod 204 to swing back and forth, the second swing rod 204 pulls the first joint pull rod 205 to move up and down, the first joint pull rod 205 pulls the third swing rod 206, and the third swing rod 206 is fixed on the stop gauge mounting rod 207. Therefore, the stop gauge mounting rod 207 can rotate within a certain range under the drive of the third swing rod 206, so that the stop gauge 208 realizes swinging.

[0035] As Figure 4 shown, the side alignment mechanism 3 includes a side alignment cam 301 provided on the cam transmission shaft 1, a right-angle roller swing rod 302 provided on the first swing arm fixed shaft 202, a second swing arm fixed shaft 306 rotatably provided on the upper side frame of the cam transmission shaft 1, a first swing arm 304 and a second swing arm 305 fixed on the second swing arm fixed shaft 306, a swing arm connecting rod 303 with two ends respectively connected to the right-angle roller swing rod 302 and the first swing arm 304, a sliding positioning mechanism provided on the upper part of the frame, and a second joint pull rod 307 with two ends respectively connected to the second swing arm 305 and the sliding positioning mechanism.

[0036] Preferably, one end of the right-angle roller swing rod 302 is connected to the swing arm connecting rod 303, and the other end is in contact with the side alignment cam 301. The first swing arm 304 and the second swing arm 305 are integrally formed and fixed on the second swing arm fixed shaft 306 at an angle to each other, or the first swing arm 304 and the second swing arm 305 are independently fixed on the second swing arm fixed shaft 306 at an angle to each other.

[0037] As Figure 1 shown, the sliding positioning mechanism includes a runner 308 rotatably fixed on the upper part of the frame, a linear shaft arranged in parallel on the upper part of the frame, a first movable component 311 and a second movable component 312 slidably arranged on the linear shaft, a first positioning plate 313 fixed on the first movable component 311, a second positioning plate 314 fixed on the second movable component 312, a third joint pull rod 316 with two ends respectively connected to the runner 308 and the first movable component 311, a fourth joint pull rod 315 with two ends respectively connected to the runner 308 and the second movable component 312, and one end of the second joint pull rod 307 is connected to the runner 308. Under the action of the second joint pull rod 307, the first movable component 311 and the second movable component 312 respectively make relative reciprocating motions along the linear shaft through the third joint pull rod 316 and the fourth joint pull rod 315.

[0038] Specifically, the linear axis includes a first linear axis 309 disposed on the upper side and a second linear axis 310 disposed on the lower side. The first movable assembly 311 includes a first slider slidably disposed on the first linear axis 309 and the second linear axis 310 and a second slider slidably disposed on the second linear axis 310. A first connecting rod is provided between the first slider and the second slider, and the first positioning plate 313 is fixed to the second slider; the second movable assembly 312 includes a third slider slidably disposed on the first linear axis 309 and the second linear axis 310 and a fourth slider slidably disposed on the second linear axis 310. A second connecting rod is provided between the third slider and the fourth slider, and the second positioning plate 314 is fixed to the fourth slider.

[0039] Further, one end of the first slider is connected to one end of the third joint pull rod 316, and one end of the third slider is connected to one end of the fourth joint pull rod 315. Driven by the third joint pull rod 316 and the fourth joint pull rod 315, the first positioning plate 313 and the second positioning plate 314 move relatively back and forth left and right simultaneously on the second linear axis 310.

[0040] During the conveying process of the thin strip, the cam transmission shaft 1 rotates, and the flat cam 301 fixed on the upper side of the cam transmission shaft 1 also rotates simultaneously. Since the outer shape of the cam transmission shaft 1 is a smooth curve with high and low points, as the cam transmission shaft 1 rotates, the cam transmission shaft 1 drives the right-angle roller swing rod 302 to swing. The right-angle roller swing rod 302 pulls the first swing arm 304 to swing through the swing arm connecting rod 303. The first swing arm 304 is fixed to the second swing arm fixing shaft 306, so the first swing arm 304 drives the rotation of the second swing arm fixing shaft 306. The second swing arm fixing shaft 306 drives the second swing arm 305 installed on the second swing arm fixing shaft 306 to swing. The up and down movement of the second joint pull rod 307 is driven by the swing of the second swing arm 305, so that the runner 308 rotates. The rotation of the runner 308 drives the third joint pull rod 316 and the fourth joint pull rod 315, causing the first movable assembly 311 and the second movable assembly 312 to move left and right. The positioning plates 1 and 2 fixed to the first movable assembly 311 and the second movable assembly 312 also move left and right simultaneously, so as to place the thin strip between the first positioning plate 313 and the second positioning plate 314.

[0041] Preferably, the second joint pull rod 307, the third joint pull rod 316 and the fourth joint pull rod 315 are arranged at intervals on the runner 308. The relative positional relationship among the second joint pull rod 307, the third joint pull rod 316 and the fourth joint pull rod 315 can ensure their relative positions by finely adjusting the lengths of the three joint pull rods through the threads on the joint pull rods. Other major positional relationships are determined by the cam curve, the length of the pull rod and the position where the runner fixes the pull rod. The stop gauge driven by the power mechanism just swings to be perpendicular to the conveying table to firmly block the thin strip, and then the power mechanism drives the positioning plate to move left and right to align the thin strips left and right; the power mechanism continues to provide the restoring power to drive the stop gauge and the positioning plate back to their original positions. Preferably, the power mechanism includes a motor or an internal combustion engine to provide rotational power for the cam transmission shaft 1.

[0042] When the thin strip is about to be conveyed to the specified position, the stop gauge driven by the rotation of the stop gauge cam just swings to be perpendicular to the conveying table (the angle of the stop gauge cam needs to be adjusted according to the product) to firmly block the thin strip, and then the positioning plate is driven to move left and right by the rotation of the side alignment cam (the angle of the side alignment cam needs to be adjusted according to the product) to align the thin strips left and right; the stop gauge cam and the side alignment cam continue to rotate to drive the stop gauge and the positioning plate back to their original positions, and the thin strip continues to be conveyed to the cross-cutting part through the intermittent mechanism (this mechanism can ensure consistent step distance and prevent forward rushing).

[0043] The thin strip positioning and aligning device of the present invention ensures that the front and rear positions of the thin strips are consistent and the left and right are aligned, providing a guarantee for improving the cutting accuracy of the notebooks, significantly improving the cutting accuracy of the notebooks. At the same time, after passing through this device, the thin strips will no longer rush forward, the thin strips are conveyed orderly, and no matter how fast the speed is, the thin strips will not be crowded and cause paper jams, improving the production efficiency.

[0044] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: the specific embodiments of the present invention can still be modified or some technical features can be equivalently replaced; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
