[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-3 As shown, a cardboard bonding device for corrugated cardboard production includes a shell component 1, an interior of the shell component 1 is provided with a through slot 102 communicating on both sides, and the inner walls on opposite sides of the through slot 102 are provided with bonding slots 105 distributed in an array and communicating with the outside, and bonding components 2 are inserted into the bonding slots 105, and the ends of each row of bonding components 2 away from the through slot 102 remain connected, the inside of the bonding components 2 is poured with adhesive, and the ends of the bonding components 2 located inside the through slot 102 remain open, and the top of the bonding component 2 is provided with an extrusion block 206 to maintain communication with the inside of the bonding component 2, and the end of the bonding component 2 located inside the through slot 102 is set as a rounded corner 208, and the top of the through slot 102 is provided with a pressing plate 104 that can maintain vertical reciprocating motion.

[0026] The main purpose of the cardboard bonding device for corrugated cardboard production is to use the squeezing block 206 located at the top of the bonding slider 201 and the rounded corner 208 at the end of the bonding slider 201 so that when the pressing plate 104 is pressed down, the corrugated cardboard on the top of the bonding slider 201 is first squeezed, and then the squeezing block 206 is driven to slide and squeeze into the inside of the bonding slider 201, so that the internal adhesive is sprayed from the spray slot 205 onto the corrugated cardboard located at the bottom of the bonding slider 201. The rounded corner 208 is set so that when the bonding slider 201 is squeezed, a lateral driving force is generated, causing it to slide outward and be removed from between the two corrugated cardboards. Then, the two corrugated cardboards are bonded by continuous downward pressure of the pressing plate 104. By pressing the squeezing block 206 downward, the bonding slider 201 can slide freely in the bonding slot 105, so that different layers of bonding sliders 201 can be extracted according to the corrugated cardboards of different thicknesses, and corrugated cardboards of different thicknesses can be bonded.

[0027] In the technical solution provided by this utility, Figure 1 、 Figure 2 and Figure 3 It can be seen that the shell component 1 includes a shell 101, and a telescopic column 103 is symmetrically arranged on the top of the through slot 102 to connect to the pressure plate 104, so as to drive the pressure plate 104 to maintain vertical reciprocating motion to squeeze the bonding component 2, drive the bonding component 2 to apply adhesive to the corrugated cardboard, and slide outward from the inside of the corrugated cardboard to perform bonding work, and a motor is arranged inside the shell component 1 to drive the telescopic column 103 to perform telescopic movement.

[0028] Furthermore, the bonding component 2 specifically includes a bonding slider 201 inserted into each bonding slot 105, and a bonding groove 202 is provided inside the bonding slider 201 for placing adhesive, and an injection groove 203 is provided at the top of the end of the bonding slider 201 away from the through groove 102 to connect to the bonding groove 202. Adhesive can be injected into the bonding groove 202 through the injection groove 203 to perform bonding on the corrugated cardboard.

[0029] Furthermore, a spraying slot 205 is provided at the end of the bonding slider 201 away from the injection slot 203 to connect to the bonding slot 202. Through the spraying slot 205, the adhesive can be applied to the top of the corrugated cardboard located at the bottom of the spraying slot 205, thereby bonding with the upper layer of corrugated cardboard.

[0030] Furthermore, rollers 207 distributed in a linear array are provided on the top of the extrusion block 206. Through the arrangement of the rollers 207, when the bonding slider 201 slides laterally by generating a lateral thrust through the arrangement of the rounded corners 208, the top of the extrusion block 206 and the corrugated cardboard placed on the top of the bonding slider 201 can maintain rolling friction, thereby reducing friction and facilitating the separation between the layers of corrugated cardboard for bonding the corrugated cardboard.

[0031] Furthermore, a connecting rod 204 is provided between the ends of each row of adhesive sliders 201 away from the through slots 102 to connect the adhesive sliders 201 of each layer and drive the adhesive sliders 201 of each layer to maintain synchronous sliding.

[0032] Furthermore, the contact surface between the adhesive slider 201 and the adhesive slot 105 is provided with a smooth coating, which can reduce friction and facilitate the adhesive slider 201 to be squeezed out of the layers of corrugated cardboard.

[0033] Working principle: First, according to the different thicknesses of corrugated cardboard, the bonding sliders 201 of each layer connected by the connecting rod 204 are inserted and pulled out, thereby changing the distance between the bonding sliders 201 of each layer to adapt to the clamping of corrugated cardboards of different thicknesses;

[0034] After all layers of corrugated cardboard are aligned and placed, the telescopic column 103 is activated to drive the pressing plate 104 downward. When the first layer of corrugated cardboard is pressed, the extrusion block 206 of the gluing slider 201 at the bottom of the corrugated cardboard is driven to slide and press into the gluing slider 201, thereby spraying the adhesive inside from the spraying slot 205 onto the top of the corrugated cardboard at the bottom of the gluing slider 201.

[0035] The rounded corners 208 are provided so that when the bonding slider 201 is squeezed, a lateral driving force is generated, causing it to slide outward and separate from between the two corrugated paperboards. Then, the pressing plate 104 is continuously pressed downward to bond the two corrugated paperboards.

[0036] By continuously pressing down the pressing plate 104, each layer of corrugated cardboard at the bottom can be bonded.

[0037] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
