Description

Technical Field

[0001] This invention relates to the field of paperboard production equipment technology, specifically to a paperboard bonding machine and its usage method. Background Technology

[0002] In current production, cardboard packaging boxes are ubiquitous. After the cardboard raw material for cardboard packaging boxes is produced, advertising paper needs to be glued onto the cardboard. After successful gluing, it is cut and bent into the corresponding packaging boxes.

[0003] Currently, cardboard bonding machines typically apply glue using a glue brush or a regular glue roller. However, glue brushes are prone to drying out, resulting in insufficient glue supply. Glue rollers, on the other hand, can force glue into the cardboard fibers due to pressure, causing the bonded cardboard to separate after pressing. Furthermore, current cardboard bonding machines often use only a conveyor belt and a pressing belt for pressing, which can also lead to insufficient pressure and separation. Summary of the Invention

[0004] The main objective of this application is to provide a baking oven mechanism and hot-drilling equipment to solve the problem of easy delamination of cardboard after pressing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cardboard bonding machine, comprising:

[0006] The feeding device includes a first fixed bracket, on which a first cardboard feeder, a second cardboard feeder, a first cardboard drive wheel frame, and a second cardboard drive wheel frame are mounted.

[0007] The glue application device includes a second fixed bracket, on which two limiting rollers are mounted, and two opposing second extrusion rollers and two opposing third extrusion rollers are also mounted. An applicator roller is mounted inside the second fixed bracket, located between the two limiting rollers. Several applicator brushes are mounted on the applicator roller, and these brushes are spiral-shaped and arranged in a circular array centered on the axis of the applicator roller.

[0008] The pressing device includes a third fixed bracket, on which a conveyor belt is fitted. A heating support plate is also fitted inside the third fixed bracket, and the heating support plate is located inside the conveyor belt and supports the conveyor belt.

[0009] In one exemplary embodiment, a plurality of first paperboard drive wheel frames are fitted together and installed at the paper outlet of a first paperboard feeder, the first paperboard drive wheel frames being used to transfer the paper output from the first paperboard feeder; and a plurality of second paperboard drive wheel frames are fitted together and installed at the paper outlet of a second paperboard feeder, the second paperboard drive wheel frames being used to transfer the paper output from the second paperboard feeder.

[0010] In one exemplary embodiment, the tangents at the discharge ends of the first cardboard drive wheel frame and the second cardboard drive wheel frame form an angle of 10-70 degrees.

[0011] In an exemplary embodiment, an adhesive applicator is installed inside the second fixed bracket. The adhesive applicator includes a fixed housing, and an adhesive storage tank is installed inside the fixed housing. A plurality of adhesive outlets are installed on one side of the adhesive storage tank. A first limiting plate and a second limiting plate are installed inside the second fixed bracket. The adhesive applicator is located between the first limiting plate and the second limiting plate. An adhesive storage box is installed on one side of the first fixed bracket. The adhesive storage box and the adhesive storage tank are connected by a connecting pipe. A corresponding adhesive pump is installed on the corresponding connecting pipe.

[0012] In one exemplary embodiment, a plurality of pressing belts are also installed on the third fixed bracket. The pressing belts are positioned above the conveyor belt and are installed in an obtuse triangle shape.

[0013] In one exemplary embodiment, the pressing belt is provided with a plurality of cardboard pressing pads arranged in a linear array, the cardboard pressing pads being in a herringbone shape.

[0014] In one exemplary embodiment, the pressing belt is provided with two cardboard edge pressing pads, which are disposed on both sides of the cardboard pressing pads.

[0015] The present invention also includes a method of using a cardboard bonding machine, comprising:

[0016] First adhesive paperboard, second adhesive paperboard and third adhesive paperboard;

[0017] The steps for converting the first and second adhesive paperboards into the third adhesive paperboard are as follows:

[0018] S1. Before use, place the first adhesive cardboard and the second adhesive cardboard to be bonded into the corresponding first cardboard feeder and second cardboard feeder respectively. The first cardboard feeder and the second cardboard feeder drive the first adhesive cardboard and the second adhesive cardboard toward the glue application device through the first cardboard drive wheel frame and the second cardboard feeder respectively.

[0019] S2, the first adhesive paperboard driven by the first paperboard drive wheel frame passes around the corresponding limiting roller, and the second adhesive paperboard driven by the second paperboard drive wheel frame first passes through the first extrusion roller and then passes around the corresponding limiting roller;

[0020] S3. The gluing device transfers the glue to the gluing roller, and the gluing roller sequentially transfers the glue to the opposite surfaces of the first bonding paperboard and the second bonding paperboard;

[0021] S4. After the first adhesive paperboard and the second adhesive paperboard are coated with glue, they are extruded and formed by the second extrusion roller and the third extrusion roller arranged opposite to each other.

[0022] The pressing step of the third adhesive cardboard is as follows:

[0023] S11, The extruded third adhesive cardboard falls onto the conveyor belt and is transported therethrough, while the heating support plate is activated to heat it.

[0024] S12. When the third adhesive paperboard passes through the pressing belt, the paperboard edge pressing pad on the pressing belt first completes the pressing and bonding operation on the two sides of the third adhesive paperboard.

[0025] S13. Next, the cardboard pressing pad on the pressing belt will further press and bond the third adhesive cardboard.

[0026] The glue application device of this invention includes a glue-applying roller and a glue-applying device arranged opposite to each other. In the actual production process, while the glue-applying roller is driven to rotate, the relative rotation direction between the glue-applying roller and the first and second adhesive paperboards installed in the glue application device is opposite. The length of the glue-applying roller from the first adhesive paperboard is greater than the length of the glue-applying roller from the second adhesive paperboard. The glue dots come into contact with the first and second adhesive paperboards in sequence. When the glue outlet of the glue application device applies glue to the glue-applying roller, the glue is first scraped off by the glue-applying brush on the glue-applying roller, forming intermittent glue dots on the spiral-shaped glue-applying brush. Under the action of the rotating glue-applying roller and the continuously moving first adhesive paperboard, the glue dots on the glue-applying brush draw diagonal glue strips on the first adhesive paperboard, and the remaining glue dots on the glue-applying brush draw diagonal glue strips on the second adhesive paperboard. The two glue strips form an "X" shaped glue strip. This glue application method can make the adhesion between the first and second adhesive paperboards tighter and effectively prevent the paperboard from cracking due to insufficient glue bonding between the first and second adhesive paperboards.

[0027] When the pressing device of this invention is in use, after the first and second adhesive cardboard are pressed together by the first and second extrusion rollers to form the third adhesive cardboard, it falls onto the conveyor belt and is transported to the area below the pressing belt. The square inlet between the pressing belt and the conveyor belt is open, which facilitates the entry of the third adhesive cardboard between the pressing belt and the conveyor belt. When the pressing belt presses the third adhesive cardboard, the third adhesive cardboard is first pressed on both sides by the cardboard edge pressing pad. This can effectively prevent the third adhesive cardboard from coming apart or the edges of the cardboard from not being pressed. After the third adhesive cardboard enters between the pressing belt and the conveyor belt, the cardboard pressing pad on the pressing belt is in a "V" shape, which allows the cardboard pressing pad to first press the middle of the third adhesive cardboard, and then gradually press other parts of the third adhesive cardboard. This makes the adhesion of the pressed third adhesive cardboard tighter and effectively prevents the cardboard from coming apart. Attached Figure Description

[0055] Reference Figure 2 As shown, according to an embodiment of this application, the feeding device 100 includes a first fixed bracket 101, on which a first cardboard feeder 102, a second cardboard feeder 104, a first cardboard drive wheel frame 103, and a second cardboard drive wheel frame 105 are mounted. The first cardboard feeder 102 is filled with a first adhesive cardboard 401, which is advertising paper. The second cardboard feeder 104 is filled with a second adhesive cardboard 402, which is cardboard.

[0056] Several first paperboard drive wheel frames 103 are installed in cooperation with the paper outlet of the first paperboard feeder 102. The first paperboard drive wheel frames 103 are used to transfer the paper output by the first paperboard feeder 102. Several second paperboard drive wheel frames 105 are installed in cooperation with the paper outlet of the second paperboard feeder 104. The second paperboard drive wheel frames 105 are used to transfer the paper output by the second paperboard feeder 104.

[0057] Reference Figure 8 As shown, according to an embodiment of this application, the tangents at the discharge ends of the first cardboard drive wheel frame 103 and the second cardboard drive wheel frame 105 form an angle of 10-70 degrees. In this embodiment, the tangents at the discharge ends of the first cardboard drive wheel frame 103 and the second cardboard drive wheel frame 105 form an angle of 40 degrees, and the lateral directions of the drive of the first adhesive cardboard 401 and the second adhesive cardboard 402 are the same.

[0058] Reference Figure 7-9 As shown in the embodiment of this application, the glue application device 200 includes a second fixed bracket 201. Two limiting rollers 203 are installed on the second fixed bracket 201. Two opposing second extrusion rollers 205 and two opposing third extrusion rollers 206 are also installed on the second fixed bracket 201. A glue application roller 202 is installed inside the second fixed bracket 201. The glue application roller 202 is located between the two limiting rollers 203. A plurality of glue application brushes 2021 are installed on the glue application roller 202. The glue application brushes 2021 are spiral-shaped and arranged in a circular array with the axis of the glue application roller 202 as the center.

[0059] A gluing device 220 is installed inside the second fixed bracket 201. The gluing device 220 includes a fixed housing 227, and a glue storage tank 226 is installed inside the fixed housing 227. Several glue outlets 225 are installed on one side of the glue storage tank 226. A first limiting plate 207 and a second limiting plate 208 are installed inside the second fixed bracket 201. The gluing device 220 is located between the first limiting plate 207 and the second limiting plate 208. The relative rotation direction between the gluing roller 202 and the first adhesive cardboard 401 and the second adhesive cardboard 402 installed in the glue brushing device 200 is opposite. The length of the gluing roller 202 from the first adhesive cardboard 401 is greater than the length of the gluing roller 202 from the second adhesive cardboard 402.

[0060] In some embodiments of this application, the glue-applying roller 202 is positioned 0.5 mm from the first adhesive cardboard 401 and 0.25 mm from the second adhesive cardboard 402. The spiral-shaped glue-applying brush 2021 on the glue-applying roller 202 is positioned 0.4 mm from the first adhesive cardboard 401 and 0.15 mm from the second adhesive cardboard 402. In this embodiment, when the glue-applying roller 202 rotates, the glue scraped off from the glue outlet 225 by the glue-applying brush 2021 is in a hemispherical shape with a radius of 0.6 mm, and is applied to the spiral-shaped glue-applying brush 2021. Intermittent glue dots are formed. Under the action of the rotating glue roller 202 and the continuously moving first bonding cardboard 401, the glue dots on the glue brush 2021 draw diagonal glue strips on the first bonding cardboard 401, and the remaining glue dots on the glue brush 2021 draw diagonal glue strips on the second bonding cardboard 402. The two glue strips form a letter "X" shaped glue strip. This glue application method can make the adhesion between the first bonding cardboard 401 and the second bonding cardboard 402 tighter, effectively preventing the cardboard from cracking due to insufficient glue adhesion between the first bonding cardboard 401 and the second bonding cardboard 402.

[0061] Reference Figure 10-14 As shown, according to an embodiment of this application, the pressing device 300 includes a third fixed bracket 301, on which a conveyor belt 305 is mounted, and a heating support plate 306 is also mounted on the inner side of the third fixed bracket 301. The heating support plate 306 is disposed on the inner side of the conveyor belt 305 and supports the conveyor belt 305.

[0062] Several pressing belts 302 are also installed on the third fixed bracket 301. The pressing belts 302 are positioned above the conveyor belt 305. The installation shape of the pressing belts 302 is an obtuse triangle. According to the embodiment of this application, the square inlet between the pressing belts 302 and the conveyor belt 305 is open. First, it facilitates the entry of the third adhesive cardboard 403 between the pressing belts 302 and the conveyor belt 305. Second, it allows the pressure to increase linearly when pressure is applied between the pressing belts 302 and the conveyor belt 305.

[0063] In some embodiments of this application, the pressing belt 302 is provided with a plurality of cardboard pressing pads 303 arranged in a linear array. The cardboard pressing pads 303 are in a "V" shape, which allows the cardboard pressing pads 303 to first press the middle of the third adhesive cardboard 403, and then gradually press the other parts of the third adhesive cardboard 403. This makes the adhesion of the third adhesive cardboard 403 after pressing tighter and effectively prevents the cardboard from coming apart.

[0064] Reference Figure 3-6As shown in the embodiment of this application, the pressing belt 302 is provided with two paperboard edge pressing pads 304. The two paperboard edge pressing pads 304 are disposed on both sides of the paperboard pressing pad 303. When the pressing belt 302 presses the third adhesive paperboard 403, the third adhesive paperboard 403 will first be pressed by the paperboard edge pressing pads 304 on both sides of the third adhesive paperboard 403. This can effectively prevent the third adhesive paperboard 403 from coming apart or the paperboard edge lines from not being pressed.

[0065] A method of using a cardboard gluing machine includes:

[0066] The steps for converting the first adhesive paperboard 401, the second adhesive paperboard 402, and the third adhesive paperboard 403 into the third adhesive paperboard 403 are as follows:

[0067] S1. Before use, place the first adhesive cardboard 401 and the second adhesive cardboard 402 to be bonded into the corresponding first cardboard feeder 102 and second cardboard feeder 104 respectively. The first cardboard feeder 102 and the second cardboard feeder 104 drive the first adhesive cardboard 401 and the second adhesive cardboard 402 toward the glue application device 200 through the first cardboard drive wheel frame 103 and the second cardboard feeder 104 respectively. The first adhesive cardboard 401 and the second adhesive cardboard 402 form an acute angle.

[0068] S2. The first adhesive paperboard 401 driven by the first paperboard drive wheel frame 103 passes around the corresponding limiting roller 203, and the second adhesive paperboard 402 driven by the second paperboard drive wheel frame 105 first passes through the first extrusion roller 204 and then passes around the corresponding limiting roller 203.

[0069] S3. The gluing device 220 transfers the glue to the gluing roller 202. The gluing roller 202 rotates in the opposite direction to the first and second adhesive paperboards 401 and 402 installed in the gluing device 200. The distance between the gluing roller 202 and the first adhesive paperboard 401 is greater than the distance between the gluing roller 202 and the second adhesive paperboard 402. The glue dots contact the first and second adhesive paperboards 401 and 402 in sequence. The glue outlet 225 of the gluing device 200 faces the gluing roller 202. 2. When applying glue, the glue is first scraped off by the glue brush 2021 on the glue roller 202, forming intermittent glue dots on the spiral-shaped glue brush 2021. Under the action of the rotating glue roller 202 and the continuously moving first adhesive cardboard 401, the glue dots on the glue brush 2021 draw diagonal glue strips on the first adhesive cardboard 401, and the remaining glue dots on the glue brush 2021 draw diagonal glue strips on the second adhesive cardboard 402. The two glue strips form a glue strip in the shape of the letter "X".

[0070] S4. After the first adhesive paperboard 401 and the second adhesive paperboard 402 are coated with glue, they are pressed into the third adhesive paperboard 403 by the second extrusion roller 205 and the third extrusion roller 206 which are arranged opposite to each other.

[0071] The pressing steps for the third adhesive paperboard 403 are as follows:

[0072] S11. The extruded third adhesive paperboard 403 falls onto the conveyor belt 305 and is transported therethrough. The heating support plate 306 starts heating, which can accelerate the drying speed of the third adhesive paperboard 403.

[0073] S12. When the third adhesive paperboard 403 passes through the pressing belt 302, the paperboard edge pressing pad 304 on the pressing belt 302 first completes the pressing and bonding operation on the two sides of the third adhesive paperboard 403, effectively preventing the third adhesive paperboard 403 from coming apart or the paperboard edge lines from not being pressed.

[0074] S13. Next, the cardboard pressing pad 303 on the pressing belt 302 will further press and bond the third adhesive cardboard 403. The cardboard pressing pad 303 on the pressing belt 302 is in the shape of a "V". This allows the cardboard pressing pad 303 to first press the middle of the third adhesive cardboard 403, and then gradually press the other parts of the third adhesive cardboard 403. This makes the bond of the third adhesive cardboard 403 after pressing tighter and effectively prevents the cardboard from coming apart.

[0075] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0076] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application. The above description is merely a preferred embodiment of this application and is not intended to limit this application. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
