Description

Technical Field

[0001] The utility model relates to the technical field of paper mounting machines, in particular to a paper pushing mechanism of a paper mounting machine. Background Art

[0002] Paper laminating machines belong to the field of paper making machinery and are mainly used to paste two pieces of paper together.

[0003] When the paper laminating machine is in the paper collection stage after the paper laminating operation, it is necessary to push the cardboard to the designated area for transfer and transportation after the cardboard is piled up to a certain amount. Traditionally, when the cardboard is piled up, it uses its own weight to slide down to the stacking area. However, the potential energy generated by the sliding of the cardboard can easily cause the cardboard to break through the temporary stacking area, resulting in the cardboard stacking being unformed, which is not conducive to subsequent transportation. For this reason, we proposed a paper pushing mechanism for the paper laminating machine to solve the above problem. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a paper pushing mechanism for a paper laminating machine, which solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: a paper-pushing mechanism for a paper-mounting machine, comprising: a main frame, a guide plate fixedly mounted on the inner wall of the main frame, a transfer trolley arranged on the side of the main frame, a baffle and a push plate arranged at the inner cavity of the main frame, a driving assembly and an adjusting assembly further arranged on the main frame, the driving assembly comprising a connecting cylinder fixedly mounted on the side of the push plate away from the baffle, an auxiliary block fixedly mounted on the end of the connecting cylinder, an electric push rod and a square rod fixedly mounted on the inner wall of the main frame, a push block fixedly mounted on the end of the output shaft of the electric push rod, and a second limit block fixedly mounted on the end of the square rod; the adjusting assembly comprises a fixed A rod, an L-shaped connecting seat fixedly mounted on the top surface of the baffle, a screw rod rotatably arranged on the main frame, two first limit blocks fixedly mounted on the top surfaces of the fixed rod and the screw rod, a protective cover body fixedly mounted on the side surface of the main frame, an auxiliary gear rotatably arranged inside the main frame, an auxiliary rack slidably arranged on the main frame, a connecting block for realizing fixed connection between the auxiliary rack and the push block, a main transmission shaft fixedly mounted on the side surface of the auxiliary gear, a main bevel gear fixedly mounted on the end portion of the main transmission shaft passing through the main frame, a secondary transmission shaft rotatably arranged on the protective cover body, a secondary bevel gear fixedly mounted on the end portion of the secondary transmission shaft, and a pulley group for realizing transmission connection between the secondary transmission shaft and the screw rod.

[0006] Preferably, the square rod is in sliding connection with the connecting tube and the auxiliary block, the second limiting block is located inside the connecting tube, and the second limiting block is also in sliding connection with the connecting tube.

[0007] Preferably, the push block is designed as an annular structure, and the connecting tube is located in the inner cavity of the push block.

[0008] Preferably, the outer diameter of the auxiliary block is larger than the outer diameter of the connecting cylinder, and the auxiliary block can contact the push block.

[0009] Preferably, there are two L-shaped connecting seats, one of which is slidingly connected to the fixed rod, and the other L-shaped connecting seat is threadedly connected to the screw rod.

[0010] Preferably, the auxiliary rack is located above the auxiliary gear, and the auxiliary rack is meshed with the auxiliary gear.

[0011] Preferably, the main bevel gear, the auxiliary bevel gear and the pulley assembly are all located in the internal cavity of the protective cover body, and the main bevel gear and the auxiliary bevel gear are meshed and transmission-connected.

[0012] Preferably, the guide plate is designed as an inclined surface, and the baffle is located on the side of the lower end of the inclined surface of the guide plate.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. The paper pushing mechanism of the paper laminating machine sets a baffle at the end point of the guide plate to prevent the cardboard from sliding off the guide plate, ensuring that the cardboard can slide onto the temporary stacking area of ​​the main frame. At the same time, the baffle can cooperate with the push plate and the side wall of the main frame to ensure the neatness of the cardboard after stacking, so as to facilitate the subsequent transfer of cardboard by the transfer vehicle.

[0015] 2. The paper pushing mechanism of the paper laminating machine is configured with a driving component in the inner cavity of the main frame, so as to utilize the electric push rod in the driving component to drive the push plate to slide, and then utilize the push plate to transfer the stacked cardboard to the transfer vehicle. Because the entire action does not require much intervention from the user, its actual use efficiency is high, and the cardboard transfer can be completed quickly. The baffle is also connected to the driving component by an adjusting component, so that when the push plate contacts the cardboard, the baffle can be moved up to open the baffle, thereby ensuring that the cardboard accumulated on the main frame can be shifted to the transfer vehicle. At the same time, under the connection of the adjusting component, when the push plate retracts to the inner cavity of the main frame, the baffle moves down synchronously to close the opening of the main frame, so as to facilitate the subsequent restriction of the cardboard from sliding.

There are two L-shaped connecting seats 52, one of which is slidingly connected to the fixed rod 51, and the other L-shaped connecting seat 52 is threadedly connected to the screw 53. The auxiliary rack 58 is located above the auxiliary gear 56, and the auxiliary rack 58 is meshed with the auxiliary gear 56. The main bevel gear 510, the auxiliary bevel gear 511 and the pulley group 513 are all located in the internal cavity of the protective cover body 55. The main bevel gear 510 is meshed with the auxiliary bevel gear 511 for transmission connection. The guide plate 2 is designed with an inclined surface, and the baffle 4 is located on the side of the lower end of the inclined surface of the guide plate 2.

[0025] Working principle: Place the cardboard processed by the paper laminating machine on the guide plate 2. Under the impact force when the cardboard is placed, the cardboard will slide down along the inclined surface of the guide plate 2 until the cardboard hits the baffle 4. The cardboard falls vertically to the temporary stacking area formed by the baffle 4, the push plate 6 and the side wall of the main frame 1. After the cardboard is piled up to a certain amount, the electric push rod 74 is started, and the push block 72 connected to the output shaft of the electric push rod 74 slides toward the push plate 6. Because the connecting cylinder 71 fixed on the push plate 6 and the square rod 75 fixed on the inner wall of the main frame 1 are in a sliding connection relationship, when the push block 72 contacts the push plate 6, the cardboard can be pushed to the transfer vehicle 3 through the push plate 6. The push block 72 also uses a connecting block 57 to be fixedly connected to the auxiliary rack 58, which is an auxiliary The rack 58 slides inside the main frame 1 together with the push block 72, and the auxiliary gear 56 meshing with the auxiliary rack 58 rotates as the auxiliary rack 58 slides, and the main bevel gear 510 is also fixed on the outer surface of the main transmission shaft 59 fixed on the auxiliary gear 56, and the sub-bevel gear 511 meshing with the main bevel gear 510 for transmission connection is fixed on the end of the sub-transmission shaft 512, and the sub-transmission shaft 512 is established in a rotationally connected relationship inside the protective cover body 55 fixed on the side of the main frame 1, and the sub-transmission shaft 512 is connected to the screw 53 through the pulley group 513. Therefore, after the auxiliary gear 56 rotates, the main transmission shaft 59, the main bevel gear 510, the sub-bevel gear 511, the sub-transmission shaft 512 and the pulley group 513 are connected. Under the transmission of the equal structure, the screw 53 rotates synchronously, and the two L-shaped connecting seats 52 fixed on the bottom surface of the baffle 4, one of the L-shaped connecting seats 52 is slidably connected to the fixed rod 51 fixed to the main frame 1, and the other L-shaped connecting seat 52 is threadedly connected to the screw 53. Therefore, when the push block 72 slides toward the push plate 6, the screw 53 rotates forward, and then drives the baffle 4 to move up through the L-shaped connecting seat 52, opening the opening of the main frame 1, and then runs the electric push rod 74 until the push plate 6 is driven to push all the accumulated cardboards into the transfer vehicle 3. The output shaft of the electric push rod 74 can be retracted, and the push block 72 drives the auxiliary rack 58 to slide back, so that the auxiliary gear 56 rotates in the opposite direction, and then the screw 53 rotates in the opposite direction synchronously, and then the L-shaped connecting seat 52 is used to drive the baffle 4 to move upward. When the push plate 72 is in the forward direction and the sliding movement is stopped, the plate 4 is in the forward direction and the sliding movement is stopped, so that the cardboard 4 is pushed upwards and the cardboard 4 is pushed downwards, and the cardboard 4 is pushed upwards and the sliding movement is stopped, so that the cardboard 4 is pushed upwards and the cardboard 4 is pushed upwards. When the push plate 72 is in the forward direction and the sliding movement is stopped, the cardboard 4 is pushed upwards and the cardboard 4 is pushed upwards, the cardboard 4 is pushed upwards and the sliding movement is stopped, so that the cardboard 4 is pushed upwards and the sliding movement is stopped,Phase 3: Push block 72 slides toward auxiliary block 73, and auxiliary rack 58 slides back, driving auxiliary gear 56 to rotate in the opposite direction. Screw 53 rotates in the opposite direction synchronously, driving baffle 4 to slide downward. Phase 4: After push block 72 contacts auxiliary block 73, it drives auxiliary block 73, connecting cylinder 71, and push plate 6 to slide back into the inner cavity of main frame 1 until push plate 6 returns to its initial position. Baffle 4 also slides down to the opening of main frame 1 synchronously, closing the opening of main frame 1.
