[0001] This utility model relates to the field of glue coating machine feeding technology, specifically a glue coating machine feeding mechanism that improves the fixation of the core roll. Background Technology
[0002] Glue applicators are a common piece of equipment in our daily production. They use air pressure to spray liquids such as glue or paint onto the desired product. The equipment employs a three-axis linkage for automated operation and is equipped with computer-programmed control of the spraying path. Spraying thickness and time are both settable, making it simple and easy to operate. Its applications are wide-ranging, playing an important role in various industries such as packaging, furniture manufacturing, automotive manufacturing, electronics, textiles, building materials, and pharmaceuticals. By evenly applying glue to the surface of an object, the glue applicator can achieve the functions of bonding, sealing, and protection, improving product quality and added value. With the advancement of technology and the demands of industrial development, the application areas of glue applicators will become increasingly widespread, and their role in manufacturing will become increasingly important.
[0003] However, in the packaging industry, the mother roll substrate may deform due to transportation issues, and the original feeding air shaft cannot smoothly feed the material, affecting the production schedule, increasing labor costs, and reducing production efficiency. To address this, a glue coating machine feeding mechanism that improves the fixation of the mother roll core is proposed. Utility Model Content

[0010] The second conical limiting sleeve is set outside the left end of the feeding shaft. A limiting ring is set at one end of the outer side of the second conical limiting sleeve. An external threaded connecting pipe is fixed at the outer side of the limiting ring near the second conical limiting sleeve. The second conical limiting sleeve and the external threaded connecting pipe are connected by a threaded engagement. The outer side of the limiting ring is provided with a second threaded hole evenly distributed along the ring.
[0011] The internal hex bolts are respectively disposed inside the second screw hole and the first screw hole, and are connected to the second screw hole and the first screw hole by thread engagement. The internal hex bolts are adapted to the limiting hole.
[0012] Preferably, an auxiliary sleeve is provided on the outside of the internal hexagonal bolt, and the auxiliary sleeve is movably connected to the internal hexagonal bolt. Three of each of the first and second screw holes are provided, and the limiting holes are symmetrically and equidistantly arranged.

[0017] (III) Beneficial Effects
[0018] Compared with the prior art, this utility model provides a glue coating machine feeding mechanism that improves the core fixing degree, and has the following beneficial effects:
[0019] This invention reduces the diameter of the feeding shaft to create a feeding shaft that, in conjunction with the disassembly of the first and second conical limiting sleeves, facilitates the installation of the mother roll substrate. After the mother roll core is installed, the second conical limiting sleeve is moved toward the mother roll substrate, and the limiting ring is fixed using an internal hex bolt. The second conical limiting sleeve is rotated to change its position, thereby clamping the mother roll substrate. This method solves the problem of the mother roll core deforming and being unable to feed material, ensuring normal production progress, reducing labor costs, and improving production efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] This utility model provides a technical solution: a feeding mechanism for a glue applicator that improves the fixation of the core roll. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 4 ,include:
[0027] The feeding shaft 1 has limit holes 2 at both ends of its exterior.
[0028] The first conical limiting sleeve 3 is located on the outside of the right end of the feeding shaft 1, and the outside of the first conical limiting sleeve 3 is provided with first screw holes 4 evenly distributed in a ring.
[0029] The second conical limiting sleeve 5 is set on the outside of the left end of the feeding shaft 1. A limiting ring 6 is set on one end of the outer side of the second conical limiting sleeve 5. An external threaded connecting pipe 8 is fixed on the outer side of the limiting ring 6 near the second conical limiting sleeve 5. The second conical limiting sleeve 5 and the external threaded connecting pipe 8 are connected by threaded engagement. The outer side of the limiting ring 6 is provided with a second threaded hole 7 evenly distributed along the ring.
[0030] The inner diameter of the conventional core is the same as the outer diameter of the shaft, and the diameter of the conventional shaft is 75mm. However, the outer diameter of the feeding shaft 1 provided by this utility model is smaller than the inner diameter of the core. The length of the feeding shaft 1 is about 2m, the effective length is about 1.4m, the circumference of the ring shaft is 16cm, and the diameter of the feeding shaft 1 is about 50mm.
[0031] The internal hex bolts 9 are respectively set inside the second screw hole 7 and the first screw hole 4, and the internal hex bolts 9 are connected to the second screw hole 7 and the first screw hole 4 by thread engagement, and the internal hex bolts 9 are adapted to the limiting hole 2.
[0032] Please see Figure 1 and Figure 4 An auxiliary sleeve 10 is fitted around the hexagon socket head cap screw 9, and the auxiliary sleeve 10 is movably connected to the hexagon socket head cap screw 9. There are three screw holes 4 and three screw holes 7. The limiting holes 2 are symmetrically and equidistantly arranged.
[0033] Please see Figure 4 Both the outer end of the auxiliary sleeve 10 and the outer end of the internal hexagon bolt 9 are provided with internal hexagon holes, which are used for inserting internal hexagon wrenches.
[0034] Please see Figure 4 An external hexagonal head 12 is fixed inside the auxiliary sleeve 10 near the internal hexagonal hole. The external hexagonal head 12 is adapted to the internal hexagonal hole. When the external hexagonal head 12 is inserted into the internal hexagonal hole, it drives the internal hexagonal bolt 9 when the auxiliary sleeve 10 rotates.
[0035] Please see Figure 4 The auxiliary sleeve 10 has extension plates 13 on both sides of its exterior, and the extension plates 13 are fixedly connected to the auxiliary sleeve 10. The extension plates 13 allow the auxiliary sleeve 10 to be turned by hand-tightening the internal hex bolts 9.
[0036] Please see Figure 4 A magnetic ring 11 is provided on the lower outer edge of the auxiliary sleeve 10, and the magnetic ring 11 is fixedly connected to the auxiliary sleeve 10. The magnetic ring 11 makes it easy for the auxiliary sleeve 10 to be magnetically attached to the outside of the internal hexagon bolt 9.
[0037] This solution involves: fitting the master roll core onto the outside of the feeding shaft 1 from one end; fitting the second conical limiting sleeve 5 and the limiting ring 6 onto the left end of the master roll core outside the feeding shaft 1; tightening the internal hex bolt 9 on the outside of the limiting ring 6 so that one end engages with the limiting hole 2, thereby fixing the limiting ring 6; then rotating the second conical limiting sleeve 5, which, under the threaded engagement with the external threaded connecting pipe 8, converts the rotational motion of the second conical limiting sleeve 5 into linear motion, thereby causing the second conical limiting sleeve 5 to move toward the master roll core and clamp and fix it; fitting the auxiliary sleeve 10 onto the outside of the internal hex bolt 9; inserting the external hex bolt head 12 of the auxiliary sleeve 10 into the internal hex bolt hole of the internal hex bolt 9; and simultaneously, the magnetic ring 11 magnetically attracts the internal hex bolt 9, making it difficult for the auxiliary sleeve 10 to fall off; and using the extension plate 13 to make the auxiliary sleeve 10 easy to turn by hand, while retaining the internal hex bolt hole for rotation with an internal hex wrench.
