[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0024] In the initial state, the binding platform 5 is in the initial position, the movable end of the cylinder push rod 4 is extended, and the two sliders 6 are away from each other. When in use, two separate cardboards are first bound into a carton prototype. The operation is as follows: the two cardboards are placed horizontally on the binding platform 5, so that the two cardboards are in contact with each other and overlapped, and the forward and reverse screws are driven to rotate forward, and the two sliders 6 are synchronously reversed to approach each other until the two sliders 6 are in contact with the cardboards and overlapped. In this process, the joints of the two cardboards are aligned by the two sliders 6, and then the pressing piece is used to align the two cardboards. The cardboard is pressed to keep the two pieces of cardboard aligned, and then the movable end of the cylinder push rod 4 is driven to be retracted, driving the binding platform 5 to slide to the limit position. At the same time, the two pieces of cardboard are bound by the binding head 2, and then the movable end of the cylinder push rod 4 is driven to extend, driving the binding platform 5 to slide to the initial position, driving the forward and reverse screws to reverse, and the two sliders 6 synchronously slide in the opposite direction until they are both away from the cardboard, and the cardboard is released by the pressing member, and then the carton prototype is bound. The operation method corresponds to the above, and no further description is given here;

[0025] To sum up, when the present application is used, the seams of two pieces of cardboard and the seams of the carton prototype can be automatically aligned and kept aligned, reducing the workload of manual participation. It is not only convenient for subsequent binding operations, but also reduces deviations and ensures the neatness of subsequent binding, so it is more practical.

[0026] like Figure 2-Figure 3As shown, in some embodiments, the pressing member includes a connecting rod 7 hinged on a slider 6, and a pressing block 8 having a frustum shape and in contact with the paperboard is provided at the free end of the connecting rod 7. The pressing block 8 is fixedly connected to the connecting rod 7. The shape of the pressing block 8 can increase the contact area with the paperboard, thereby improving the pressing effect.

[0027] In the initial state, the connecting rod 7 tends to the vertical direction. Referring to the above, when the two sliders 6 slide synchronously in opposite directions until they both contact and overlap with the cardboard, the connecting rod 7 is driven to rotate to the horizontal direction, and the holding block 8 contacts and overlaps with the cardboard, thereby pressing the cardboard. Conversely, the connecting rod 7 is driven to rotate to the vertical direction, and the holding block 8 moves away from the cardboard, thereby releasing the pressure on the cardboard.

[0028] like Figure 3 As shown, in some embodiments, a driving member is provided on the slider 6 and the connecting rod 7. When the slider 6 slides, the connecting rod 7 is driven to rotate by the driving member;

[0029] Referring to the above, when the two sliders 6 slide in opposite directions synchronously until they both come into contact with and overlap the cardboard, the connecting rod 7 is driven by the driving member to rotate to a horizontal direction, that is, the two connecting rods 7 rotate in opposite directions together, which is more convenient to use. Conversely, when the two sliders 6 slide in opposite directions synchronously until they are away from the cardboard, the connecting rod 7 is driven by the driving member to rotate to a vertical direction.

[0030] like Figure 3 As shown, in some embodiments, the driving member includes a slide bar 9 which is slidably arranged on the slider 6 and overlaps with the paperboard, the slide bar 9 slides in the horizontal direction, a driving rack 10 is arranged on the slide bar 9, the driving rack 10 is in the horizontal direction and fixed on the slide bar 9, a driving gear 11 which meshes with the driving rack 10 is arranged on the connecting rod 7, the driving gear 11 is in the vertical direction and fixed on the connecting rod 7, a torsion spring 12 is arranged at the hinge of the connecting rod 7 and the slider 6, and the two ends of the torsion spring 12 are fixedly connected to the connecting rod 7 and the slider 6 respectively;

[0031] Referring to the above, in the initial state, the connecting rod 7 tends to the vertical direction, the torsion spring 12 is in a natural state, and the two slide bars 9 approach each other. When the two sliders 6 slide in the opposite direction synchronously until they both contact and overlap with the cardboard, the cardboard forces the two slide bars 9 to slide in the opposite direction together until they are away from each other, and the two driving racks 10 move with the two slide bars 9 respectively. The two driving gears 11 rotate in the opposite direction together due to the meshing action, and the two connecting rods 7 rotate in the opposite direction together until they are both horizontal, and the two torsion springs 12 are squeezed. Conversely, when the two sliders 6 slide in the opposite direction synchronously until they are away from the cardboard, the two torsion springs 12 are reset to the natural state, and the two connecting rods 7 rotate in the opposite direction together due to elastic potential energy until they both tend to the vertical direction, and the two driving gears 11 rotate with the two connecting rods 7 respectively. The two driving racks 10 move in the opposite direction together, and the two slide bars 9 slide in the opposite direction together until they are close to each other.

[0032] like Figure 5 As shown, in some embodiments, the machine body 1 is provided with two synchronously oppositely sliding moving frames 13, the moving frames 13 slide in the horizontal direction, and the moving frames 13 are rotatably provided with a plurality of supporting wheels 14 which are all in rolling contact with the paperboard, and the plurality of supporting wheels 14 are all in the horizontal direction and are distributed in an array in the horizontal direction;

[0033] Referring to the above, in the initial state, the two moving frames 13 are close to each other. When in use, the two moving frames 13 are driven to slide in opposite directions synchronously to move away from each other. When the two pieces of cardboard are placed horizontally on the binding platform 5, the two pieces of cardboard are respectively in contact with and overlapped with the multiple support wheels 14 on the two moving frames 13. The cardboard is supported by the multiple support wheels 14 together, so that there is no need for manual support of the cardboard, which is more convenient to use. At the same time, it avoids bending of the cardboard due to gravity and improves the stability of use. When the binding platform 5 slides, the cardboard and the multiple support wheels 14 are rolled and overlapped. Conversely, when binding the carton prototype, the two moving frames 13 are driven to slide in opposite directions synchronously to move closer to each other.

[0034] like Figure 5 As shown, in some embodiments, an electric push rod 15 is provided on the machine body 1, the electric push rod 15 is in a horizontal direction and fixed on the machine body 1, a transverse block 16 is provided at the movable end of the electric push rod 15, the transverse block 16 is fixed at the movable end of the electric push rod 15, two connecting rods 17 are symmetrically hinged on the transverse block 16, the two connecting rods 17 are both in a horizontal direction, and the free ends of the two connecting rods 17 are respectively hinged to the two moving frames 13;

[0035] Referring to the above, in the initial state, the two mobile frames 13 are close to each other, the movable end of the electric push rod 15 is retracted, and the two connecting rods 17 tend to be parallel. When in use, the movable end of the electric push rod 15 is extended to drive the transverse block 16 to move in the horizontal direction. The two connecting rods 17 rotate synchronously in opposite directions around their respective corresponding hinge points until they tend to be collinear. The two mobile frames 13 are driven to slide synchronously in opposite directions until they are away from each other through the two connecting rods 17. Conversely, when the movable end of the electric push rod 15 is retracted, the two mobile frames 13 slide synchronously in opposite directions until they are close to each other.

[0036] like Figure 6 As shown, in some embodiments, a support member acting on the carton prototype is provided on the machine body 1, which is used to support or release the support of the carton prototype;

[0037] Referring to the above, when the carton prototype is bound, it is supported by the support member, so that there is no need for manual support of the carton prototype, which is more convenient to use and avoids bending of the cardboard due to gravity, thereby improving the stability of use. Conversely, when the carton prototype is bound, the support member is used to release the support.

[0038] like Figure 6 As shown, in some embodiments, the support member includes two moving blocks 18 that are both slidably arranged on the machine body 1, and the moving blocks 18 slide in the horizontal direction. The machine body 1 is rotatably provided with a positive and negative screw rod 19, and the positive and negative screw rod 19 is in the horizontal direction. The two moving blocks 18 are respectively threadedly matched with the positive and negative thread segments of the positive and negative screw rod 19, and the moving block 18 is hinged with a support rod 20, and the free ends of the two support rods 20 are hinged with a support plate 21, and the support plate 21 is in the horizontal direction.

[0039] With reference to the above, in the initial state, the two moving blocks 18 are away from each other, the two support rods 20 are both tending to the horizontal direction, and the support plate 21 is close to the positive and negative screw rods 19. When in use, the positive and negative screw rods 19 are driven to rotate forward, and the two moving blocks 18 are synchronously slid in the opposite directions due to the action of the positive and negative threads until they are close to each other, and the two support rods 20 are synchronously rotated around their respective corresponding hinge points until they are both tending to the vertical direction, and the two support rods 20 are used to drive the support plate 21 to slide upward together until the carton prototype is rolled and overlapped with multiple support rollers 22, so as to support the carton prototype, and at the same time can adapt to carton prototypes of different sizes, improve applicability and flexibility, conversely, the positive and negative screw rods 19 are driven to reverse, and the two moving blocks 18 are synchronously slid in the opposite directions due to the action of the positive and negative threads until they are away from each other, and the two support rods 20 are synchronously rotated around their respective corresponding hinge points until they are both tending to the horizontal direction, and the two support rods 20 are used to drive the support plate 21 to slide downward together until the carton prototype is away from the multiple support rollers 22, and the support of the carton prototype can be released.
