DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 4As shown, the utility model discloses a laminating device for producing cardboard 10, which is composed of a workbench 1, a conveying assembly 2 and a pressing roller 3. The conveying assembly 2 is located on the workbench 1, and the pressing roller 3 is located above the workbench 1 and is rotatably connected to the workbench 1. The cardboard 10 is formed by bonding multiple plate-like structures together. Therefore, when laminating is required: after the cardboard 10 to be laminar is placed on the workbench 1, the cardboard 10 can be driven by the conveying assembly 2 to move toward the bottom of the pressing roller 3. When the pressing roller 3 contacts the cardboard 10, the rotating pressing roller 3 can apply pressure to the cardboard 10 during the movement of the cardboard 10 so that the various parts of the cardboard 10 are tightly combined. The utility model also includes a plate placing frame 4 whose shape is adapted to the cardboard 10 located on the conveying assembly 2, and left limit members located on the left and right sides of the plate placing frame 4. 5 and the right limit member 6 and the transmission assembly 7 for driving the pressing roller 3 and the conveying assembly 2 to work, the length directions of the left limit member 5 and the right limit member 6 are extended forward and backward, the pressing roller 3 is against the upper end surface of the plate setting frame 4, and the cardboard 10 to be pressed is placed in the plate setting frame 4. At this time, since the left limit member 5 is located on the left side of the plate setting frame 4 and the right limit member 6 is located on the right side of the plate setting frame 4, when the plate setting frame 4 is located on the workbench 1 and moves toward the bottom of the pressing roller 3, the path of the plate setting frame 4 moving forward and backward can be limited by the left limit member 5 and the right limit member 6. Therefore, when the pressing roller 3 is located directly above the plate setting frame 4 and the pressing roller 3 presses the cardboard 10 in the plate frame 4, the plate setting frame 4 pressed by the pressing roller 3 will not appear on the workbench 1. Shaking and offset will not affect the pressing effect.

[0021] The transmission assembly 7 includes a motor 71, a working gear 72, a front gear 73 and a rear gear 74. The conveying assembly 2 includes a front conveying rod 21 extending in the longitudinal direction along the front and rear directions, a plurality of front conveying wheels 211 arranged at intervals on the front conveying rod 21, a rear conveying rod 22 and a plurality of rear conveying wheels 221 located on the rear conveying rod 22. The rear gear 74 is located on the rear conveying rod 22 and is fixedly connected to the motor 71 by means of a key connection, a coupling, etc. The front gear 73 is located on the front conveying rod 21 and meshes with the rear gear 74. The working gear 72 is located on the pressure roller 3 and meshes with the rear gear 74. After the motor 71 is started, the motor 71 can drive the rear gear 74 and the rear conveying rod 22 fixed with the rear gear 74 to rotate and drive the rear conveying rod 2 2 rotates, and because the front gear 73 and the working gear 72 are both engaged with the rear gear 74, the pressure roller 3, the front conveying rod 21 and the front conveying wheel 211 can be driven to rotate. Since the motor 71 is started, the pressure roller 3, the front conveying rod 21 and the rear conveying rod 22 can be driven to rotate synchronously. Therefore, the rotating front conveying wheel 211 and the rear conveying wheel 221 can drive the plate placing frame 4 to move so that it moves to the right below the pressure roller 3, so that the cardboard 10 located in the plate placing frame 4 is pressed by the force of the pressure roller 3. Since the front gear 73 is engaged with the rear gear 74 and the working gear 72, after starting the motor 71, the pressure roller 3, the front conveying rod 21 and the rear conveying rod 22 can be started and work synchronously at the same time without starting multiple power sources, making the operation more convenient.

[0022] The conveying assembly 2 further includes a front mating rod 23 and a rear mating rod 24 extending in the longitudinal direction. The front mating rod 23 is provided with front mating wheels 231 at intervals, and the rear mating rod 24 is provided with rear mating wheels 241 at intervals. The front mating rod 23 is located at the front side of the front conveying rod 21, and the rear mating rod 24 is located at the rear side of the rear conveying rod 22. The transmission assembly 7 further includes a front mating gear 75 on the front mating rod 23, a rear mating gear 242 on the rear mating rod 24, a first mating gear 232 on the front conveying rod 21, and a rear mating gear 241 on the rear conveying rod 22. The second mating gear 76 on the feeding rod 22, the first synchronous belt 77 transmitted between the rear mating gear 242 and the second mating gear 76, and the second synchronous belt 78 transmitted between the first mating gear 232 and the front mating gear 75, 1. Due to the existence of the front mating rod 23 and the rear mating rod 24 and the front mating wheel 231 and the rear mating wheel 241, the plate frame 4 can be affected by the front conveying wheel 211 and the rear conveying wheel 221 when it is located on the front mating wheel 231 and the rear mating wheel 241, and continue to move backwards. After being pressed, it can be away from the pressing roller 3, and because the front mating wheel 231 and the rear mating wheel 241 make the stroke of the plate frame 4 longer, the stroke of manual movement is reduced, which brings convenience to use; 2. Because the first synchronous belt 77 is transmitted and arranged between the rear mating gear 242 and the second mating gear 76, and the second synchronous belt 78 is transmitted and arranged between the first mating and the front mating gear 75, when the motor 71 is started and drives the front conveying rod 21, the rear conveying rod 22 and the pressing roller 3 to rotate, at this time, the front conveying rod 21 drives the first mating gear 232 to rotate to realize the passage The front mating gear 75 is driven to rotate by the first synchronous belt 77. Similarly, the rear conveying rod 22 drives the second mating gear 76 to rotate, and the rear mating gear 242 is driven to rotate by the second synchronous belt 78. The front mating gear 75 and the rear mating gear 242 are respectively fixed on the front mating rod 23 and the rear mating rod 24, thereby realizing the rotation of the front mating rod 23 and the rear mating rod 24 to realize the rotation of the front mating wheel 231 and the rear mating wheel 241. Therefore, while the front mating wheel 231 and the rear mating wheel 241 extend the stroke of the plate frame 4, no new power source is added.

[0023] Preferably, it further includes a left guide 8 and a right guide 9. The length direction of the plate placing frame 4 extends left and right. The plate placing frame 4 includes a placing cavity 41. The left guide 8 and the right guide 9 are respectively slidably installed on the left and right sides of the placing cavity 41. Since the left guide 8 and the right guide 9 are respectively slidably installed on the left and right sides of the placing cavity 41, when the width of the cardboard 10 loaded into the placing cavity 41 changes, the positions of the left guide 8 and the right guide 9 can be adjusted so that the left guide 8 is located on the left side of the cardboard 10 in the placing cavity 41, and the right guide 9 is located on the right side of the cardboard 10 in the placing cavity 41, thereby limiting the position of the cardboard 10 in the placing cavity 41 and reducing the possibility of the cardboard 10 in the placing cavity 41 moving randomly due to size changes and affecting the pressing effect.

[0024] Among them, positioning columns 81 are protrudingly provided on the front and rear sides of the left guide member 8, and the plate placing frame 4 is provided with positioning grooves 42 corresponding to the intervals between the left guide columns. After the cardboard 10 to be pressed is placed in the placing cavity 41, the left guide member 8 is placed in the placing cavity 41 so that each positioning column 81 can be respectively inserted into the corresponding positioning groove 42, thereby realizing the position determination of the left guide member 8 in the plate placing frame 4, so that the left guide member 8 can be against the left side of the cardboard 10.

[0025] Preferably, the plate frame 4 is made of a material that is easily deformed, such as rubber. Therefore, when the left guide member 8 needs to be removed from the plate frame 4, the front and rear sides of the plate frame 4 can be stretched and deformed outward more smoothly, thereby separating the positioning column 81 from the corresponding positioning groove 42 to achieve the position adjustment of the left guide member 8 in the plate frame 4.

[0026] Preferably, the workbench 1 includes a baffle 11 at the rear side. Due to the existence of the baffle 11, after the cardboard 10 is pressed, the cardboard placing frame 4 moving backward will not separate from the workbench 1 and fall down, causing the cardboard 10 to fall.

[0027] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
