[0007] The upper end of the working plate is fixedly connected to two first positioning strips located to the right of the glue box, and the upper end of the working plate is fixedly connected to a second positioning strip located behind the two first positioning strips;
[0008] The upper end of the working plate is fixedly connected to an arc-shaped positioning plate located to the left of the glue box;
[0009] Vertical plates are fixedly connected to both sides of the upper surface of the working plate. A lead screw is rotatably connected to one side of the two vertical plates facing each other. The lead screw is driven by a second motor installed at the right end of the right vertical plate. A moving block is threadedly connected to the outer wall of the lead screw. An electric telescopic rod is fixedly connected to the lower end of the moving block. A connecting plate is fixedly connected to the lower end of the electric telescopic rod. A guide block is provided below the connecting plate. A guide hole is opened at the upper end of the guide block. A sliding rod extending into the guide hole is fixedly connected to the lower end of the connecting plate. A spring sleeved on the outer wall of the sliding rod is fixedly connected between the guide block and the connecting plate. An electromagnet is installed at the lower end of the guide block.
[0010] To improve the stability of the moving block's movement, in a preferred embodiment of this utility model for applying adhesive to cardboard with metal sheets, a guide rod is fixedly connected between the two upright plates, penetrating the moving block and slidably connected thereto.
[0011] To prevent relative rotation between the slide rod and the guide block, and to prevent the slide rod from dislodging from the interior of the guide hole, in a preferred embodiment of the gluing device for attaching iron sheets to cardboard according to this utility model, limit grooves are provided on both the left and right sides of the inner wall of the guide hole, and limit sliders that are fixedly connected to the slide rod are slidably connected inside the two limit grooves.
[0012] To facilitate the placement of the cardboard between the two first positioning strips and the second positioning plate, in a preferred embodiment of the gluing device for attaching metal sheets to cardboard according to this utility model, the corners at the upper ends of the opposite sides of the two first positioning strips and the corners at the upper front side of the second positioning plate are both set as rounded corners.
[0013] In order to improve the ease of operation by pushing the iron sheet into the interior of the arc-shaped positioning plate at the upper end of the work plate, the arc-shaped positioning plate is preferably a semi-circular structure in the preferred glue application device for attaching iron sheets to cardboard according to this utility model.
[0014] To facilitate the support and fixation of the device, in a preferred embodiment of the present invention for applying adhesive to cardboard with metal sheets, the lower end of the working plate is fixedly connected with multiple mounting brackets.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] The iron sheet is positioned using an arc-shaped positioning plate, and the cardboard is positioned using two first positioning strips and a second positioning plate. The glue-soaked sponge at the bottom rotates to the upper position, where it comes into contact with the iron sheet via an electromagnet. A spring prevents direct collision between the electromagnet and the iron sheet. The electromagnet, when energized, provides attraction to the iron sheet. The electromagnet and the attracted iron sheet move upwards a certain distance and then to the right a certain distance. The iron sheet then moves downwards to contact the glue-soaked sponge, allowing glue to adhere to the lower end of the iron sheet. The iron sheet then moves upwards a certain distance and then to the right a certain distance, now positioned directly above the glued area on the cardboard. The iron sheet moves downwards to contact the cardboard again, again with the spring preventing direct collision. When the electromagnet is de-energized, it moves upwards a certain distance, completing both the glue application and the bonding of the iron sheet. This improves work efficiency and reduces operational difficulty. Attached Figure Description

[0022] Please see Figures 1 to 4 A gluing device for attaching metal sheets to cardboard includes a working plate 1, with a glue tank 2 connected through the upper end of the working plate 1. A rotating shaft 3 is rotatably connected inside the glue tank 2. A first motor 6 with its output end fixedly connected to the rotating shaft 3 is installed at the right end of the glue tank 2. A movable column 4 is fixedly connected to the outer wall of the rotating shaft 3. Adhesive-soaked sponges 5 are fixedly connected to both the upper and lower sides of the movable column 4 through mounting plates. A glue pump 20 with its discharge end extending into the glue tank 2 is installed at the left end of the glue tank 2.
[0023] The upper end of the working plate 1 is fixedly connected to two first positioning strips 7 located to the right of the glue box 2, and the upper end of the working plate 1 is fixedly connected to a second positioning strip 8 located behind the two first positioning strips 7.
[0024] An arc-shaped positioning plate 9 located to the left of the glue box 2 is fixedly connected to the upper end of the working plate 1;
[0025] Upright plates 10 are fixedly connected to both sides of the upper surface of the working plate 1. A lead screw 11 is rotatably connected to one side of the two upright plates 10. The lead screw 11 is driven by a second motor 21 installed at the right end of the right upright plate 10. A moving block 12 is threadedly connected to the outer wall of the lead screw 11. An electric telescopic rod 13 is fixedly connected to the lower end of the moving block 12. A connecting plate 14 is fixedly connected to the lower end of the electric telescopic rod 13. A guide block 15 is provided below the connecting plate 14. A guide hole 16 is opened at the upper end of the guide block 15. A slide rod 17 extending into the guide hole 16 is fixedly connected to the lower end of the connecting plate 14. A spring 18 sleeved on the outer wall of the slide rod 17 is fixedly connected between the guide block 15 and the connecting plate 14. An electromagnet 19 is installed at the lower end of the guide block 15.
[0026] In this embodiment: When in use, the circular iron sheet is first inserted into the arc-shaped positioning plate 9, and then the arc-shaped positioning plate 9 positions the iron sheet. At the same time, the cardboard is placed on the upper end of the working plate 1, and the cardboard is made to contact the opposite side of the two first positioning strips 7 and the front end of the second positioning strip 8, thereby positioning the cardboard. It should be noted that the spacing between the two first positioning strips 7 is set according to the length of the cardboard, and the position of the second positioning strip 8 is set according to the glue application position on the cardboard. Thus, when the cardboard contacts the front end of the second positioning strip 8, the iron sheet placed inside the arc-shaped positioning plate 9 is horizontally aligned with the glue application position on the cardboard.
[0027] Subsequently, the first motor 6 drives the rotating shaft 3 and the movable column 4 to rotate 180 degrees, thereby causing the glue-soaked sponge 5 on the lower side to rotate to the upper position. The glue will submerge the glue-soaked sponge 5 when it rotates to the lower position. Then, the electric telescopic rod 13 drives the connecting plate 14, the sliding rod 17, the guide block 15, and the electromagnet 19 to move downward a certain distance until the electromagnet 19 abuts against the iron piece inside the arc-shaped positioning plate 9. During the abutment process, the iron piece will provide a reaction force to the electromagnet 19 and the guide block 15, which will cause the spring 18 to contract, thereby avoiding direct collision between the electromagnet 19 and the iron piece and reducing mechanical stress. Then, the electromagnet 19 is energized to provide an attraction force to the iron piece. After the electromagnet 19 and the attracted iron piece move upward a certain position, the second motor 21 drives the lead screw 11 to rotate, thereby causing the moving block 12 to move to the right a specified distance, and at the same time driving the electric telescopic rod 17 to rotate downward. 3. The electromagnet 19 and the attracted iron sheet move a certain distance to the right. At this time, the iron sheet is directly above the glue-soaked sponge 5. Then, the iron sheet moves downward a certain distance to contact the glue-soaked sponge 5, so that the glue adheres to the lower end of the iron sheet. Then, the iron sheet moves upward a certain distance and then moves to the right a certain distance. At this time, the position of the iron sheet is directly above the glue application position on the cardboard. Then, the iron sheet moves downward until it abuts against the cardboard. Through the contraction of the spring 18, the iron sheet and the cardboard are prevented from directly colliding. At this time, the electromagnet 19 is de-energized. Then, the electromagnet 19 moves upward a certain distance, completing the glue application and the pasting of the iron sheet. During this process, another iron sheet can be placed. During the rework, the pasted cardboard is removed and another cardboard is placed, thereby improving work efficiency and reducing the difficulty of operation.
[0028] After working for a period of time, the glue pump 20 will automatically pump a certain amount of glue into the glue tank 2 to replenish the glue.
[0029] As a technical optimization of this utility model, a guide rod is fixedly connected between the two upright plates 10 and slidably connected to the through movable block 12.
[0030] In this embodiment, a guide rod is provided to improve the stability of the movement of the moving block 12.
[0031] As a technical optimization of this utility model, limit grooves are provided on both the left and right sides of the inner wall of the guide hole 16, and limit sliders that are fixedly connected to the slide rod 17 are slidably connected inside the two limit grooves.
[0032] In this embodiment, by setting two limiting slide grooves, the relative rotation between the slide rod 17 and the guide block 15 is prevented, and the slide rod 17 is prevented from leaving the interior of the guide hole 16.
[0033] As a technical optimization of this utility model, the corners at the upper ends of the opposite sides of the two first positioning strips 7 and the corners at the upper front side of the second positioning strip 8 are all set as rounded corners.
[0034] In this embodiment, a rounded corner is set to facilitate the cardboard entering the position between the two first positioning strips 7 and the second positioning plate strip 8.
[0035] As a technical optimization of this utility model, the arc-shaped positioning plate 9 has a semi-circular structure.
[0036] In this embodiment, by setting the arc-shaped positioning plate 9 as a semi-circular structure, it is not necessary to pick up the iron sheet. The iron sheet can be directly pushed into the interior of the arc-shaped positioning plate 9 from the upper end of the working plate 1, which improves the convenience of operation.
[0037] As a technical optimization of this utility model, the lower end of the working plate 1 is fixedly connected with multiple mounting brackets.
[0038] In this embodiment, multiple mounting brackets are provided to facilitate the support and fixation of the device.
[0039] Working principle: In use, firstly, the circular iron sheet is inserted into the arc-shaped positioning plate 9, and then the arc-shaped positioning plate 9 positions the iron sheet. At the same time, the cardboard is placed on the upper end of the working plate 1, and the cardboard is in contact with the opposite side of the two first positioning strips 7 and the front end of the second positioning strip 8, thereby positioning the cardboard. It should be noted that the spacing between the two first positioning strips 7 is set according to the length of the cardboard, and the position of the second positioning strip 8 is set according to the glue application position on the cardboard. When the cardboard contacts the front end of the second positioning strip 8, the iron sheet placed inside the arc-shaped positioning plate 9 is horizontally aligned with the glue application position on the cardboard.
[0040] Subsequently, the first motor 6 drives the rotating shaft 3 and the movable column 4 to rotate 180 degrees, thereby causing the glue-soaked sponge 5 on the lower side to rotate to the upper position. The glue will submerge the glue-soaked sponge 5 when it rotates to the lower position. Then, the electric telescopic rod 13 drives the connecting plate 14, the sliding rod 17, the guide block 15, and the electromagnet 19 to move downward a certain distance until the electromagnet 19 abuts against the iron piece inside the arc-shaped positioning plate 9. During the abutment process, the iron piece will provide a reaction force to the electromagnet 19 and the guide block 15, which will cause the spring 18 to contract, thereby avoiding direct collision between the electromagnet 19 and the iron piece and reducing mechanical stress. Then, the electromagnet 19 is energized to provide an attraction force to the iron piece. After the electromagnet 19 and the attracted iron piece move upward a certain position, the second motor 21 drives the lead screw 11 to rotate, thereby causing the moving block 12 to move to the right a specified distance, and at the same time driving the electric telescopic rod 17 to rotate downward. 3. The electromagnet 19 and the attracted iron sheet move a certain distance to the right. At this time, the iron sheet is directly above the glue-soaked sponge 5. Then, the iron sheet moves downward a certain distance to contact the glue-soaked sponge 5, so that the glue adheres to the lower end of the iron sheet. Then, the iron sheet moves upward a certain distance and then moves to the right a certain distance. At this time, the position of the iron sheet is directly above the glue application position on the cardboard. Then, the iron sheet moves downward until it abuts against the cardboard. Through the contraction of the spring 18, the iron sheet and the cardboard are prevented from directly colliding. At this time, the electromagnet 19 is de-energized. Then, the electromagnet 19 moves upward a certain distance, completing the glue application and the pasting of the iron sheet. During this process, another iron sheet can be placed. During the rework, the pasted cardboard is removed and another cardboard is placed, thereby improving work efficiency and reducing the difficulty of operation.
[0041] After working for a period of time, the glue pump 20 will automatically pump a certain amount of glue into the glue tank 2 to replenish the glue.
[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
