[0038] The embodiments of the present application will be described below. Figures 1 to 10 The embodiments of the present application will be described below.

[0039] Referring to Figure 1 The present embodiment relates to a hardcover cover packaging machine, comprising: a rack, a conveying device 1 is arranged on the rack, a bottom paper feeding device 4, a first gluing device 5, a interlayer feeding device 2, a glue coating device 3 and a cover paper feeding device 6 are arranged in turn along the conveying direction of the conveying device 1;

[0040] The bottom paper feeding device 4 comprises a bottom paper feeding member for transferring the bottom paper to the conveying device 1;

[0041] The first gluing device 5 comprises a gluing mechanism for gluing the top surface of the bottom paper;

[0042] The interlayer feeding device 2 comprises a horizontal transfer mechanism 21 and a grabbing mechanism 22 for transferring the interlayer to the glued bottom paper;

[0043] The glue coating device 3 comprises a glue gun 321 facing the conveying device 1;

[0044] The cover paper feeding device 6 comprises a cover paper feeding mechanism for transferring the cover paper to the interlayer coated with glue.

[0045] The hardcover cover packaging machine loads the bottom paper through the bottom paper feeding device 4, glues the bottom paper through the first gluing device 5, transfers the interlayer to the bottom paper and bonds the interlayer to the bottom paper through the interlayer feeding device 2, then glues the bottom paper through the first gluing device 5 to bond the soft material to the bottom paper, then coats glue on the interlayer through the glue coating device 3, and finally transfers the cover paper to the soft material through the cover paper feeding device 6 to bond the cover paper to the soft material, thereby automatically realizing the packaging of the hardcover cover in sequence.

[0046] The bottom paper feeding device 4 can adopt a bottom paper feeding device 4 in the prior art, which can include a bottom paper bin for storing bottom paper, a bottom paper outlet is designed below the bottom paper bin, and then a bottom paper ejection mechanism in the bottom paper ejection device drives the bottom paper on the lower side of the bottom paper bin to be ejected from the bottom paper outlet.

[0047] The gluing mechanism in the embodiment can be a gluing mechanism in a paper sheet gluing machine or a gluing mechanism in a local transfer gluing machine. The interlayer can be a sponge material.

[0048] Further, referring to Figures 2 to 4 The conveying device 1 comprises a conveying assembly and a positioning assembly; the conveying assembly comprises a first conveying surface 111 arranged on the rack; the positioning assembly comprises a first baffle 122 and an elastic positioning member 121, both of which are arranged on the rack, and a positioning channel is formed between the first baffle 122 and the elastic positioning member 121.

[0049] The conveying device 1 forms a positioning channel through the arrangement of the first baffle 122 and the elastic positioning member 121, and when the paperboard is conveyed along the first conveying surface 111, it enters the positioning channel, and under the action of the elastic positioning member 121, the paperboard is pressed on the first baffle 122, ensuring that the paperboard is attached to the first baffle 122, thereby achieving accurate lateral positioning of the paperboard on the conveying belt without the need for a driver and with high positioning accuracy.

[0050] The conveying assembly comprises a feeding support plate, a circulating mechanism and a push flag, the feeding support plate is fixed on the rack, the first conveying surface 111 is formed on the feeding support plate, the first conveying surface 111 is provided with a clearance groove for the movement of the push flag, and the circulating mechanism is arranged on the rack and drives the push flag to move back and forth along the clearance groove. Since the elastic positioning member 121 of the positioning assembly needs to be in contact with the material placed on the first conveying surface 111 for positioning when the first conveying surface 111 is positioned, the elastic positioning member 121 causes a certain resistance to the material, and the conveying assembly in the embodiment adopts the form of a feeding support plate, a circulating mechanism and a push flag, the pushing force of the push flag is strong when the material is placed on the first conveying surface 111, the pushing is stable, the material and the first conveying surface 111 do not slip, and the conveying of the material on the first conveying surface 111 is reliable. The conveying assembly in the embodiment is used in combination with the positioning assembly, which can ensure reliable positioning and reliable movement of the material on the first conveying surface 111. In addition, when the material is double-layer material, for example, when an interlayer is placed on the bottom paper, the pushing mode of the push flag can prevent the interlayer and the bottom paper from slipping, further ensuring reliable movement.

[0051] The elastic positioning piece 121 is a spring. The spring has the advantage of low cost.

[0052] The elastic positioning piece 121 is inclinedly arranged, and gradually approaches the first baffle along the running direction of the first conveying surface 111. When the paperboard is placed on the first conveying surface 111 and moves, the paperboard is easily positioned in the positioning channel between the first baffle 122 and the elastic positioning piece 121.

[0053] The number of the elastic positioning piece 121 is multiple, and the elastic positioning piece 121 gradually approaches the first baffle 122 along the advancing direction of the first conveying surface 111. The multiple elastic positioning pieces 121 are arranged, and the elastic force of the elastic positioning piece 121 acts on the paperboard more uniformly, and the paperboard is better attached to the first baffle.

[0054] The positioning assembly further comprises a spring connecting plate 123 and a spring screw. The spring connecting plate 123 comprises a vertical plate 1231 and a horizontal plate 1232 connected together. The vertical plate 1231 is provided with a protruding hole 12311 and a fixing hole 12312. The elastic positioning piece 121 passes through the protruding hole 12311 and extends to the first baffle 122. The spring screw is screwed with the fixing hole 12312 through the elastic positioning piece 121. The horizontal plate 1232 is provided with a limiting groove 12321 adjacent to one side of the vertical plate 1231. The elastic positioning piece 121 abuts against the side surface of the limiting groove 12321 adjacent to the first baffle 122 under the pressing action of the spring screw. The elastic positioning piece 121 passes through the protruding hole 12311 and has a tendency to swing towards the first baffle under the action of the spring screw. The abutment between the limiting groove 12321 and the elastic positioning piece 121 determines the position of the first end of the elastic positioning piece 121 adjacent to the first baffle 122, eliminates the influence of the uncertain position of the spring screw fixing the spring, ensures the accurate position of the elastic positioning piece 121, and thus the stress on the paperboard entering the positioning channel is more uniform, which is more conducive to accurately positioning the paperboard and protecting the paperboard.

[0055] The conveying assembly further comprises a width adjusting member for adjusting the distance between the elastic positioning piece and the first baffle 122. The width adjusting member is arranged to adjust the distance between the elastic positioning piece and the first baffle 122, so that the width of the positioning channel is adjustable.

[0056] The width adjusting member comprises a first width adjusting screw 131 and a first nut seat 132, the first width adjusting screw 131 is rotationally connected to the frame, the first nut seat 132 is threadedly connected to the first width adjusting screw 131, and the first nut seat 132 is connected to the first baffle 122. Thus, the first baffle 122 is moved by rotating the first width adjusting screw 131 through the first nut seat 132, so as to adjust the distance between the first baffle 122 and the elastic positioning member 121, and adjust the width of the positioning channel.

[0057] The width adjusting member further comprises a second nut seat 134 and a second width adjusting screw 133, the second width adjusting screw 133 is drivingly connected to the first width adjusting screw 131, the rotation direction of the second width adjusting screw 133 is opposite to that of the first width adjusting screw 131, and the second nut seat 134 is connected to the elastic sheet connecting plate 123. When the first width adjusting screw 131 is rotated, the first width adjusting screw 131 and the second width adjusting screw 133 will move the first nut seat 132 and the second nut seat 134 in opposite directions at the same time due to the opposite rotation directions of the first width adjusting screw 131 and the second width adjusting screw 133, which is convenient for adjustment on one hand, and keeps the middle line position of the positioning channel unchanged, which is better matched with the production line on the other hand.
