DETAILED DESCRIPTION

[0019] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1 , Figure 2As shown, a bottom glue machine comprises a base 1, frame plates 2 are symmetrically arranged on both sides of the base 1, the frame plates 2 are vertically arranged on both sides of the base 1, and a glue application area is formed between them, a glue application groove 3 is fixedly arranged in the glue application area, and the glue application groove 3 can be arranged on the crossbeam between the frame plates 2, a bearing seat is arranged on the frame plate 2 above the glue application area, and a glue application roller 4 is arranged on the bearing seat, and a part of the glue application roller 4 is located in the glue application groove 3 when working, and a scraper mechanism for controlling the glue layer is also arranged in the glue application area; a side of the frame plate 2 is directed to The upper extension forms a frame arm 5, and a machine head 6 is arranged on the top of the frame arm 5. A guide device for the product to be glued and a winding roller 8 for winding the product after gluing are arranged in the machine head 6; adjusting arms 9 are hingedly arranged on both sides of the outside of the frame arm 5, one end of the adjusting arm 9 extends above the upper glue roller 4, and a gluing roller 10 is rotatably arranged at the end, and the gluing roller 10 corresponds to the position of the gluing roller 4, and an adjusting mechanism is arranged at the other end of the adjusting arm 9; the gluing roller 4 and the winding roller 8 are both driven by a motor arranged on the base 1.

[0021] During operation, the adjustment arm 9 is raised by the adjustment mechanism to separate the glue roller 10 from the glue roller 4, and the glued product is passed around the guide device and then passed between the glue roller 10 and the glue roller 4 and wound around the glue roller 10. The end is stuck on the winding roller 8, and glue is injected into the glue groove 3 so that the glue roller 4 is partially submerged in the glue. The position of the scraper mechanism is adjusted according to the thickness of the required glue layer so that the end of the scraper is parallel to the surface of the glue roller 4 and has an appropriate gap, and then the adjustment mechanism is used to bring the glue roller 10 and the glue roller 4 close to the working position. Start the equipment, the scraper will smooth and evenly spread the glue, and then apply it to the product to be glued at the contact position between the glue roller 10 and the glue roller 4. The glue roller 10 itself does not need to be driven, and can be driven by the rotation of the winding roller 8.

[0022] In a preferred embodiment of the present invention, Figure 1 As shown, the guide device includes a plurality of guide rollers 7 which are staggeredly distributed in the machine head 6 and are parallel to the glue coating roller 10. The guide rollers 7 are alternately arranged to play a certain tensioning role on the glue-coated product during the operation of the equipment.

[0023] In a preferred embodiment of the present invention, Figure 1 The adjustment mechanism includes an adjustment cylinder 11, which is arranged on the side of the frame arm 5 away from the glue roller 4. One end of the adjustment cylinder 11 is hinged to the end of the adjustment arm 9 away from the glue roller 4, and the other end is hinged to the base 1. The adjustment cylinder 11 can be a pneumatic cylinder or a hydraulic cylinder, which is driven by an external hydraulic station.

[0024] In a preferred embodiment of the present invention, Figure 1, a limiting device is also provided on the adjusting mechanism. The limiting devices are generally arranged in groups, including a limiting base 121 fixedly arranged on the machine head 6, a limiting rod 13 fixedly arranged on the limiting base 121, the limiting rod 13 extends vertically downward, and is arranged directly opposite the top of the adjusting arm 9. The extension length of the limiting rod 13 can be adjusted, and a high-strength screw rod can generally be used. A corresponding limiting surface is provided on the top of the adjusting arm 9. The limiting device can extend a sufficient length as needed to control the distance between the glue coating roller 10 and the upper glue roller 4 to ensure uniform coating thickness. At the same time, it can also be used as a locking mechanism during equipment maintenance or preparation for operation to prevent the adjusting arm 9 from falling and injuring people due to failure of the adjusting cylinder 11.

[0025] In a preferred embodiment of the present invention, Figure 1 The glue tank 3 is fixedly connected to the base 1 through a support rod 14, and the support rod 14 is height-adjustable.

The first scraper 18 mechanism includes an adjustment seat 15 fixedly arranged above the gluing groove 3 and located on the side of the gluing roller 4 close to the adjustment arm 9. The adjustment seat 15 generally uses a rotatable cylinder 16. The surface of the cylinder 16 structure is provided with a plurality of mounting holes extending through the middle shaft. The first scraper 18 is fixed in the mounting hole by a locking nut 17. The direction is adjusted by rotating the cylinder 16. When the position is appropriate, the locking nut 17 is rotated to the deepest position to support the shaft and lock the cylinder 16. Figure 3 Generally, the first scraper 18 extends obliquely upward to the surface of the glue roller 4, mainly to scrape off the excess glue and make it flow back into the glue groove 3. Since there is no contact, the scraper will not be subjected to too much force, and the locking nut 17 can be locked.

[0027] In a preferred embodiment of the present invention, Figure 1 and Figure 4 The first scraper 18 mechanism is also provided with a second scraper 21 mechanism, and the second scraper 21 mechanism includes a fixed seat 19 fixedly provided on the frame plate 2, and a second scraper 21 tilted downward is slidably provided on the top of the fixed seat 19. The second scraper 21 can be fixed on the fixed seat 19 by a lockable sliding guide rail 20, and the end of the second scraper 21 is parallel to the surface of the glue roller 4, and the distance is adjusted and locked by the sliding guide rail 20, which is mainly used to control the thickness of the glue layer. The material of the scraper is generally selected according to the material of the glue, which is not easy to be bonded with glue.

[0028] In a preferred embodiment of the present invention, Figure 5 The bearing seats at both ends of the glue coating roller 10 and the upper glue roller 4 can be buckled on the frame arm 5 or the adjustment arm 9 through a press sleeve. Taking the upper glue roller 4 as an example, the press sleeve includes a press sleeve seat 22 fixed to the frame arm 5, one end of the press sleeve seat 22 is hingedly provided with a buckling plate 23, and the other end is provided with a threaded hole, and the other end of the buckling plate 23 is provided with a corresponding hole, and a closed press sleeve is formed by bolts, and a slot 24 for placing the bearing seat is provided inside the press sleeve, and the bearing seat is arranged in the slot 24 according to different bearings.
