By adopting the relationship between the width of the base 11 and the width of the support plate 21, not only can the exposed part of the waste paper block be suspended for bundling, but also the base 11 cooperates with the rectangular bottom plate 12 to jointly form the square seat plate 1 with the same size as the square pressing plate 51 during the compression of the waste paper, so as to ensure that the waste paper is stably compressed into the required block shape.

[0026] Further, the turnover assembly one 4 includes a pair of hinge seats one 41 fixed to one side of the two L-shaped door plate one 22 or the two L-shaped door plate two 23, a pair of sliding blocks one 42 slidingly arranged on one side of the support plate 21, a pair of connecting rods one 43 having two ends respectively hinged to the two pairs of hinge seats one 41 and the sliding blocks one 42, a hydraulic telescopic cylinder two 44 fixed to one side of the support plate 21, a connecting plate 45 fixed to the head of the piston rod of the hydraulic telescopic cylinder two 44, and a pair of connecting rods two 46 having one end hinged to the connecting plate 45 and the other end hinged to the two sliding blocks one 42, the two sliding blocks one 42 being located in the middle of the two hinge seats one 41 and horizontally sliding relative to the side wall of the support plate 21, and the piston rod of the hydraulic telescopic cylinder two 44 driving the connecting plate 45 to rise and fall in the middle of the two sliding blocks one 42.

[0027] By adopting the above-mentioned turnover assembly one 4, when it is necessary to drive the two L-shaped door plate one 22 or the two L-shaped door plate two 23 to turn over, first, the hydraulic telescopic cylinder two 44 retracts or extends the piston rod, so that the connecting plate 45 connected to the top end of the piston rod rises or falls, then the two connecting rods two 46 hinged to one end of the connecting plate 45 pull or push the two sliding blocks two 62 to slide away from or close to each other on one side of the support plate 21, since the two ends of the connecting rod one 43 are respectively hinged to the two pairs of sliding blocks two 62 and the hinge seats one 41, and the two hinge seats one 41 are respectively fixed to the two L-shaped door plate one 22 or the L-shaped door plate two 23, therefore, under the sliding of the two sliding blocks two 62 away from or close to each other, finally the two connecting rods one 43 pull or push the two L-shaped door plate one 22 or the L-shaped door plate two 23 to turn over relative to the support plate 21 away from or close to the base 11, so as to realize the effect of controlling the synchronous relative turning of the two L-shaped door plate one 22 or the two L-shaped door plate two 23.

[0028] Further, a horizontal T-shaped slide rail 211 is fixedly arranged on the side wall of the support plate 21, and a T-shaped slide groove 421 is formed in the two slide blocks 42 to allow the T-shaped slide rail 211 to slide through. The connecting plate 45 is arranged below the T-shaped slide rail 211 to ascend and descend. By using the sliding connection structure of the T-shaped slide rail 211 and the T-shaped slide groove 421, the sliding stability of the two slide blocks 42 on the side of the support plate 21 can be effectively ensured.

[0029] Further, the locking assembly 7 for locking the horizontal posture of the turnover plates 52 is further included. The locking assembly 7 includes two pairs of locking seats 71 fixed to the sides of the two turnover plates 52, a moving plate 72 slidingly arranged on the top of the pressing plate 51, two pairs of locking rods 73 fixed to the opposite sides of the two moving plates 72, locking holes 711 formed in the locking seats 71 and allowing the locking rods 73 to pass through, a rotating shaft 74 horizontally arranged on the moving plate 72 and slidingly passing through the two moving plates 72, two external threads 741 formed in the side walls of the rotating shaft 74 and having opposite rotation directions, a pair of nuts 75 fixed to the opposite sides of the two moving plates 72 and threadedly connected to the two external threads 741 of the rotating shaft 74, a bevel gear one 76 fixed to the middle part of the rotating shaft 74, a motor 77 fixed to the top of the pressing plate 51, and a bevel gear two 78 fixed to the output end of the motor 77 and engaged with the bevel gear one 76. The two moving plates 72 are slidingly arranged on the pressing plate 51 to approach or move away from the two pairs of locking seats 71. A pair of support seats one 511 is fixedly arranged on the top of the pressing plate 51, and the two ends of the rotating shaft 74 are rotatably connected to the two support seats one 511. The motor 77 is located between the two moving plates 72.

[0030] By using the above locking assembly 7, when it is necessary to lock the horizontal and flush posture of the turnover plates 52 and the pressing plate 51, the motor 77 is first driven to drive the bevel gear two 78 to engage and drive the bevel gear one 76 to rotate the rotating shaft 74. Then, the two nuts 75 threadedly connected to the two external threads 741 of the rotating shaft 74 are driven to move the two moving plates 72 to approach the two turnover plates 52, respectively. Finally, the locking rods 73 on the sides of the two moving plates 72 are inserted into the locking holes 711 of the two pairs of locking seats 71 on the two turnover plates 52, respectively, to lock the turnover movement of the turnover plates 52 and keep the flush state with the pressing plate 51, thereby stabilizing the top of the compacted waste paper.

[0031] Further, a guide rod one 512 slidingly passing through the two moving plates 72 is fixedly arranged on the top of the pressing plate 51. A pair of support seats two 513 supporting the two ends of the guide rod one 512 are fixedly arranged on the top of the pressing plate 51. The guide rod one 512 and the rotating shaft 74 are parallel to each other and close to the two ends of the moving plate 72, respectively. By using the guide rod one 512 and the support seats, the sliding arrangement of the moving plate 72 on the pressing plate 51 can be reasonably achieved, and the sliding stability of the two moving plates 72 above the pressing plate 51 can be effectively ensured.

[0032] Further, the top of the pressing plate 51 is fixedly provided with a protective box 514 covering the bevel gear one 76 and the bevel gear two 78, the rotating shaft 74 penetrates through the protective box 514, the motor 77 is fixed on the top of the protective box 514, and the output end of the motor 77 penetrates into the protective box 514 to connect the bevel gear two 78. By adopting the protective box 514, the engagement transmission safety of the bevel gear one 76 and the bevel gear two 78 can be safely protected.

[0033] Further, the turnover assembly two 6 includes four connecting rods three 61 hingedly connected to two pairs of locking seats 71 respectively, two pairs of sliding blocks two 62 slidingly arranged on the top of the pressing plate 51 and hingedly connected to the other ends of the four connecting rods three 61 respectively, and a push plate 63 fixed to one side of the sliding blocks two 62. The moving plates 72, the rotating shaft 74 and the guide rod one 512 are located between the two pairs of sliding blocks two 62. The push plate 63 is arranged on the side of the sliding blocks two 62 facing the rotating shaft 74 or the guide rod one 512 and is parallelly located between the two moving plates 72. When the moving plates 72 move away from the locking seats 71, the push plate 63 and the sliding blocks two 62 can be pushed to slide relative to the pressing plate 51.

[0034] By adopting the turnover assembly two 6, when the locking assembly 7 releases the locking of the turnover plate 52, the two moving plates 72 will jointly slide toward the middle of the pressing plate 51. After the locking rods 73 exit the locking holes 711 and move away from above the turnover plate 52, the two moving plates 72 continue to slide. In the process of sliding, the push plate 63 in the turnover assembly two 6 pushes the sliding blocks two 62 to slide relative to the pressing plate 51. Finally, the connecting rods three 61 hingedly connected to the sliding blocks two 62 and the locking seats 71 at two ends will pull the turnover plate 52 to turn relative to the pressing plate 51 under the sliding of the sliding blocks two 62, so as to realize the effect of automatic turnover of the turnover plate 52 by using the power of the movement of the moving plates 72. When the locking assembly 7 locks the turnover plate 52, the moving plates 72 move toward the direction of the turnover plate 52, and the locking rods 73 on one side of the moving plates 72 push the side of the turnover plate 52, so that the turnover plate 52 turns back to the horizontal state.

[0035] Further, the top of the pressing plate 51 is provided with four guide rods two 515 slidingly penetrating through the four sliding blocks two 62 respectively, and a pair of support seats three 516 fixedly arranged on the top of the pressing plate 51 and supporting the two ends of the guide rods two 515 respectively. By adopting the guide rods two 515 and the support seats three 516, the sliding arrangement of the sliding blocks two 62 on the pressing plate 51 can be reasonably realized, and the sliding stability of the sliding blocks two 62 on the pressing plate 51 can be effectively guaranteed.

[0036] Further, the guide rod two 515 is sleeved with a spring 517, and two ends of the spring 517 are fixedly connected with the support seat three 516 and the sliding block two 62 respectively. By adopting the spring 517, when the locking assembly 7 locks the turnover plate 52, the moving plate 72 moves towards the direction of the turnover plate 52, and the spring 517 which is compressed in advance pushes the sliding block two 62 reversely, and the turnover plate 52 is reversely turned over through the connecting rod three 61. When the locking rod 73 on one side of the moving plate 72 enters the active area of the turnover plate 52, the turnover plate 52 is completely turned over to the horizontal state, so that the locking rod 73 does not need to push the turnover plate 52 to turn over.

[0037] The working principle of the embodiment is as follows: when the waste paper is compressed, first, the waste paper to be compressed is poured into the square frame 2 composed of the two L-shaped door plates one 22, the two L-shaped door plates two 23 and the two support plates 21, then the hydraulic telescopic cylinder one 31 is started to drive the square plate body 5 composed of the pressing plate 51 and the two turnover plates 52 to horizontally descend from the top opening of the square frame 2 into the interior, and finally the square seat plate 1 composed of the base 11 and the rectangular bottom plate 12 turns the waste paper in the square frame 2 into waste paper blocks under the continuous approach of the square plate body 5. When the waste paper blocks need to be bundled and taken out, first, the two sets of turnover assemblies one 4 drive the two pairs of L-shaped door plates one 22 and L-shaped door plates two 23 to turn over relative to the two support plates 21 away from the base 11, then the turnover assemblies two 6 drive the two turnover plates 52 to turn over relative to the two sides of the pressing plate 51 away from the waste paper blocks, and finally when the angle between the rectangular bottom plate 12 at the bottom of the L-shaped door plate one 22 and the L-shaped door plate two 23 and the base 11 is more than ninety degrees and the angle between the turnover plate 52 and the pressing plate 51 is more than ninety degrees, the two end portions of the waste paper blocks are exposed. At this time, the exposed portions of the waste paper blocks are only needed to be bundled and tightened, so that the waste paper block bundling process can be easily completed, and the whole process does not need complicated traction and banding tasks. Since the inner walls of the support plates 21 and the base 11 are smooth and complete, and the opening positions on the two sides are not blocked, the taking-out process is relatively easier than that of the traditional waste paper compression and packaging machine.
