[0046] Combine the following Figures 1 to 5 The embodiments of the utility model are described.

[0047] A positioning and pushing cardboard aligning device in this embodiment includes:

[0048] frame;

[0049] The book receiving mechanism comprises a first book receiving mounting plate 11, a second book receiving mounting plate 12, a first supporting plate 151 and a second supporting plate 152. The first book receiving mounting plate 11 and the second book receiving mounting plate 12 are arranged to be spaced apart from each other on the left and right sides. The first supporting plate 151 and the second supporting plate 152 are both arranged below the first book receiving mounting plate 11. The first supporting plate 151 and the second supporting plate 152 can be opened.

[0050] A front positioning mechanism, a front positioning plate 31 for positioning the cardboard book in the front-to-back direction, wherein the front positioning plate 31, the first book receiving mounting plate 11, the second book receiving mounting plate 12, the first support plate 151, and the second support plate 152 together define a book receiving position for positioning the cardboard book;

[0051] The pushing mechanism 5 is used to push the paperboard book into the book receiving mechanism to the front positioning plate 31;

[0052] A book receiving plate 4, located below the book receiving mechanism;

[0053] The ejection mechanism ejects the paperboard book from the book receiving plate 4 .

[0054] A positioning, pushing and aligning device for cardboards of the utility model is configured with a book receiving mechanism and a front positioning mechanism to form a book receiving position. When the cardboard book is pushed into the book receiving position by the aligning mechanism 5, it is positioned. After the cardboard book is positioned in the book receiving position, the first support plate 151 and the second support plate 152 are opened to make the cardboard book fall to the book receiving plate 4 below, and then the cardboard book is pushed out by the pushing mechanism, thereby realizing the positioning of the cardboard book. Since the cardboard book is opened and dropped when leaving the book receiving position, the wear on the bottom surface of the cardboard book is small.

[0055] After the cardboard book is pushed into the book receiving position by the pushing mechanism 5, the front side of the cardboard book contacts the front positioning plate 31, which may cause interference when the cardboard book falls. For this reason, the front positioning mechanism also includes a front positioning driver 37, which is arranged on the frame and is drivingly connected to the front positioning plate 31. After completing the positioning of the cardboard book, the front positioning driver 37 drives the front positioning plate 31 to retreat away from the cardboard book to avoid interference from the front positioning plate 31 when the cardboard book falls.

[0056] In order to adjust the position of the front positioning plate 31 to the cardboard book of suitable specifications, the front positioning mechanism also includes a front positioning guide sleeve 32 arranged on the frame, a front positioning guide column 33 sliding along the front positioning guide sleeve 32, a front positioning mounting plate 34 fixedly connected to the front positioning guide column 33, a front positioning screw rod 35 rotatably arranged on the frame, and a front positioning screw sleeve 36 fixedly connected to the front positioning mounting plate 34. The front positioning driver 37 is installed on the front positioning mounting plate 34, and the front positioning screw rod 35 is threadedly connected to the front positioning screw sleeve 36 to adjust the position of the front positioning plate 31. When the front positioning screw rod 35 rotates, the front positioning mounting plate 34 is driven to slide along the front positioning guide column 33 and the front positioning guide sleeve 32 through the front positioning screw sleeve 36, so that the position of the front positioning plate 31 can be adjusted. This structure simply realizes the front and rear position adjustment of the front positioning plate 31.

[0057] Specifically, the pushing mechanism 5 includes a pushing driver 51 provided on the frame, and a pushing plate 52 driven by the pushing driver 51, and the pushing plate 52 is used to push the cardboard book into the book receiving position for positioning. After the cardboard book falls on the first support plate 151 and the second support plate 152, the pushing driver 51 drives the pushing plate 52 to move to the front positioning plate 31, so that the cardboard book can be positioned at the book receiving position.

[0058] The ejection mechanism includes an ejection left and right driver 61 disposed on the frame and an ejection plate 62 driven by the ejection left and right driver 61. When the cardboard book falls on the book receiving plate 4, the ejection left and right driver 61 moves to extend rightward to eject the cardboard book from the book receiving plate 4 to the subsequent conveying belt.

[0059] In order to make the ejection plate 62 reset without being hindered by the cardboard book, the book receiving plate 4 is provided with an ejection lifting avoidance groove 41 for the ejection plate 62 to extend, and the ejection mechanism also includes an ejection lifting driver 63, which is driven by the ejection left and right drivers 61, and the ejection lifting driver 63 drives the ejection plate 62 to move up and down in and out of the ejection lifting avoidance groove 41. After the ejection left and right drivers 61 drive the ejection plate 62 to move right to eject the cardboard book, the ejection lifting driver 63 drives the ejection plate 62 to move down to below the ejection lifting avoidance groove 41 and return to the left of the book receiving position, and then the ejection lifting driver 63 drives the ejection plate 62 to return to the top of the ejection lifting avoidance groove 41 to reset the ejection plate 62.

[0060] Specifically, the book receiving mechanism includes:

[0061] A first opening and closing driver 13 is provided on the frame;

[0062] The first driving member 131 is driven by the first opening and closing driver 13 to move along a straight line;

[0063] A first guide rail 141 and a second guide rail 142, wherein the first guide rail 141 and the second guide rail 142 are respectively hinged to two ends of the first driving member 131;

[0064] A first sliding block 143 and a second sliding block 144 , wherein the first sliding block 143 slides along the first guide rail 141 , and the second sliding block 144 slides along the second guide rail 142 ;

[0065] The first support plate 151 is hinged to the first book receiving and mounting plate 11 and fixed to the first sliding block 143;

[0066] The second supporting plate 152 is hinged to the second book receiving and mounting plate 12 and fixed to the second sliding block 144 .

[0067] The book receiving mechanism is provided with a first support plate 151 and a second support plate 152. After the back of the cardboard book is sent to the book receiving position, the first support plate 151 and the second support plate 152 are swung outward by the opening and closing driver, so that the cardboard book can fall away from the book receiving position used as a positioning position. The cardboard book does not need to leave the positioning position in a sliding manner, thereby reducing the wear on the bottom surface of the cardboard book.

[0068] In the initial state, the first support plate 151 and the second support plate 152 are both located below the first book receiving mounting plate 11 and the second book receiving mounting plate 12 to support the cardboard book. The action process of the opening and closing driver driving the first support plate 151 and the second support plate 152 is as follows: the opening and closing driver drives the first driving member 131 to extend outward, so that the first guide rail 141 and the second guide rail 142 expand outward and open outward, and the first guide rail 141 and the second guide rail 142 open outward through the first slider 143 and the second slider 144 respectively, so that the first support plate 151 set on the first slider 143 and the second support plate 152 set on the second slider 144 are also opened respectively, and the cardboard book falls from between the first support plate 151 and the second support plate 152, and the cardboard book leaves the book receiving position. When leaving, the cardboard book does not rub against the first support plate 151 and the second support plate 152 of the book receiving position, thereby reducing the wear on the cardboard book.

[0069] The first book receiving mounting plate 11 slides left and right along the frame; the book receiving mechanism also includes a book receiving width adjustment component, which is used to adjust the distance between the first book receiving mounting plate 11 and the second book receiving mounting plate 12, so that the first book receiving mounting plate 11 and the second book receiving mounting plate 12 can be adjusted to adapt to different widths.

[0070] In this embodiment, the second book receiving installation plate 12 slides left and right along the frame to increase the adjustment range of the distance between the first book receiving installation plate 11 and the second book receiving installation plate 12 and to increase the adaptation range.

[0071] Specifically, the book receiving width adjustment assembly includes a first guide post 171 provided on the frame, and a first guide sleeve (not shown) sliding along the first guide post 171, wherein the first guide post 171 and the first guide sleeve are respectively fixedly connected to the frame and the first book receiving mounting plate 11;

[0072] The book receiving width adjustment assembly includes a first screw sleeve 163 connected to the first book receiving installation plate 11, a first screw rod 161 threadedly connected to the first screw sleeve 163, and a second driving member driving the first screw rod 161 to rotate. When the first screw rod 161 is driven to rotate by the second driving member, the first screw rod 161 causes the first screw sleeve 163 to drive the first book receiving installation plate 11 to slide along the first guide column 171, thereby changing the distance between the first book receiving installation plate 11 and the second book receiving installation plate 12. This structure simply and conveniently realizes the distance adjustment between the first book receiving installation plate 11 and the second book receiving installation plate 12.

[0073] Furthermore, the book receiving and width adjusting component also includes a second guide column 172 arranged on the frame and a second guide sleeve (not shown in the figure) sliding along the second guide column 172, and the second guide column 172 and the second guide sleeve are respectively fixed to the frame and the second book receiving mounting plate 12; the book receiving and width adjusting component includes a second screw sleeve 164 connected to the second book receiving mounting plate 12, and a second screw rod 162 threadedly connected to the second screw sleeve 164, the second screw rod 162 has an opposite rotation direction to the first screw rod 161, and the second screw rod 162 is transmission-connected to the first screw rod 161. The second screw rod 162 is transmission connected to the first screw rod 161 and rotates in opposite directions. When the first screw rod 161 is driven by the second driver to rotate, the first screw rod 161 and the second screw rod 162 respectively drive the first screw sleeve 163 and the second screw sleeve 164 to rotate in opposite directions, thereby driving the first book receiving mounting plate 11 and the second book receiving mounting plate 12 to move in the desired direction, so that the front and rear center positions of the first book receiving mounting plate 11 and the second book receiving mounting plate 12 remain unchanged when the spacing is adjusted, so as to dock with the upstream and downstream of the production line.

[0074] The first supporting plate 151 is in an “L” shape, the upper side of the first supporting plate 151 is hinged to the first book receiving and mounting plate 11 , and the lower side of the first supporting plate 151 extends between the first book receiving and mounting plate 11 and the second book receiving and mounting plate 12 .

[0075] The second supporting plate 152 is L-shaped, the upper side of the second supporting plate 152 is hinged to the second book receiving and mounting plate 12 , and the lower side of the second supporting plate 152 extends between the second book receiving and mounting plate 12 and the second book receiving and mounting plate 12 .

[0076] The second driving member is a knob, which can conveniently and manually rotate and drive the first screw rod 161.

[0077] Furthermore, the first book receiving installation plate 11 and the second book receiving installation plate 12 are respectively provided with a first guide plate 181 and a second guide plate 182 on the entrance side of the book receiving position, and the first guide plate 181 and the second guide plate 182 together form an open structure so that the paperboard book can enter the book receiving position through the first guide plate 181 and the second guide plate 182.
