Description

Technical Field

[0001] The utility model relates to the field of surface connection using hot melt adhesive, in particular to a double-table bonding machine. Background Art

[0002] There are many types of lining packaging. For example, a packaging box made of pearl cotton is made by heat-bonding multiple pearl cotton sheets: after the pearl cotton is heated, the heated side becomes sticky, and the two sheets are combined to form the packaging box.

[0003] However, when the pearl cotton is thermally bonded, the heating effect will cause the heating surface of the pearl cotton to be lost, resulting in a decrease in the overall heating surface thickness. Therefore, the overall size of the assembled packaging material will also become smaller. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a double-table bonding machine, which reduces the overall heat loss of the packaging material and reduces production costs by coating a layer of glue on the pearl cotton.

[0005] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a double-table bonding machine, comprising a heating device and two movable workstations, the heating device being located between the two movable workstations, and characterized in that it also comprises a gluing device, the movable workstation having a placement surface for transporting the plate, and the liquid outlet on the gluing device facing the placement surface.

[0006] Furthermore, the gluing device includes a scraper, a glue coating roller, a heating tube, and a baffle. The scraper is inclined relative to the placement surface, and the baffles are distributed on both sides of the scraper surface. The glue coating roller is adjacent to the side of the scraper facing the placement surface, and after pressing against the baffle, it forms a glue groove for accommodating plastic particles. The heating tube is arranged in the lower heating plate, so that a liquid outlet for the flow of plastic solution is formed between the heating plate and the glue coating roller.

[0007] Furthermore, it also includes an adjustment mechanism for adjusting the size of the liquid outlet, and the adjustment mechanism includes a fixed seat, a top plate, and a first adjustment screw. The top plate is fixed on the fixed seat, and the first adjustment screw is rotatably set on the top plate, and its threaded end is threadedly connected to the scraper plate.

[0008] Furthermore, it also includes a manipulator and a linear motion mechanism, and the output end of the linear motion mechanism is connected to the manipulator.

[0009] Furthermore, it also includes a driving motor, the driving motor and a gear set, and the driving motor is connected to the glue coating roller through the gear set.

[0010] Furthermore, a second adjusting screw is included, which passes through the top plate and is threadedly connected to the baffle.

[0011] Beneficial effects of the utility model:

[0012] The gluing device included in the utility model applies a layer of glue on the plate. When the two plates are bonded to each other, the glue serves as a medium for connecting the two plates, which can reduce the loss caused by hot stamping, thereby eliminating the effect of the size reduction caused by the melting of the plates.

[0020] The gluing device included in the utility model applies a layer of glue on the plate. When the two plates are bonded to each other, the glue serves as a medium for connecting the two plates, which can reduce the loss caused by hot stamping, thereby eliminating the effect of the size reduction caused by the melting of the plates.

[0021] The above-mentioned gluing device includes a scraper 21, a glue roller 22, a heating tube 23, and a baffle 24. The heating plate 21 is inclined relative to the placement surface, and the baffles 24 are distributed on both sides of the surface of the scraper 21. The glue roller 22 is adjacent to the side of the scraper 21 facing the placement surface, and after resisting the baffle 24, it forms a glue groove for accommodating plastic particles. The heating tube 23 is arranged in the scraper 21, so that a liquid outlet for the flow of plastic solution is formed between the scraper 21 and the glue roller 22. It should be noted that the thickness of the pearl cotton in the moving station can support the contact between the pearl cotton and the glue roller 22. The glue flows to the glue roller 22, and the glue roller 22 evenly applies the glue on the pearl cotton.

[0022] Furthermore, it also includes an adjusting mechanism for adjusting the size of the liquid outlet, the adjusting mechanism includes a fixing seat 31, a top plate 32, and a first adjusting screw 33, the top plate 32 is fixed on the fixing seat 31, the first adjusting screw 33 is rotatably set on the top plate 32, and its threaded end is threadedly connected to the scraper plate 21; in the preparation material of the packaging box, pearl cotton is not the only choice, and the softening index of other materials may be higher or lower than that of pearl cotton. At this time, it is necessary to adjust the size of the liquid outlet to control the thickness of the glue on the pearl cotton. Therefore, the adjusting mechanism is to make further selections on the size of the liquid outlet based on the selected packaging box material.

[0023] Furthermore, it also includes a manipulator and a linear moving mechanism, the output end of the linear moving mechanism is connected to the manipulator; the pearl cotton is transported back and forth between the heating device 2 and the moving station.

[0024] Furthermore, it also includes a drive motor 34, which has a gear set, and the drive motor 34 is connected to the glue roller 22 through the gear set; its purpose is to save a lot of manpower through the electric form, and at the same time, the electric drive method can make the glue more uniform.

[0025] Furthermore, a second adjusting screw 35 is included, which passes through the top plate 32 and is threadedly connected to the baffle 24; its purpose is to provide an external force to ensure that the baffle 24 can fully contact with the glue roller 22 to prevent glue leakage.

[0026] The operating principle of this utility model:

[0027] S1, first heat the plastic particles so that the glue tank is filled with glue;

[0028] S2, the first pearl cotton and the second pearl cotton are placed on the two mobile stations respectively. When the first mobile station 41 is transporting the first pearl cotton to the rack 1, the glue flows from the sol tank to the glue coating roller, and the sol roller contacts the surface of the first pearl cotton to achieve uniform glue coating on the surface of the first pearl cotton; the second mobile station 42 transports the second pearl cotton to the rack 1, and the manipulator in the rack 1 clamps the second pearl cotton and sends the second pearl cotton to the heating device 2, which heats the second pearl surface and softens the side in contact with the heating device 2;

[0029] S3, the robot puts the second pearl cotton on the first pearl cotton, and after standing still, the two are attached to each other and then taken out from the rack 1.

The output end of the screw lifting mechanism 51 is connected to the needle box 54. The puncture needles are evenly distributed on the bottom surface of the needle plate 53. The needle plate 53 is located in the needle box 54 and is wrapped by the needle box 54. The needle feeding cylinder 52 is arranged on the needle box 54, and its piston rod is inserted into the needle box 54 and connected to the needle plate 53 to drive the needle plate 53 to move up and down. The bottom surface of the needle box 54 is provided with a through hole for the puncture needle to pass through. After the puncture needle passes through the through hole, it pierces into the pearl cotton, so that the pearl cotton is connected to the puncture needle, thereby moving the pearl cotton back and forth between different mobile stations and ironing plates.
