Description

Technical Field

[0001] The utility model belongs to the technical field related to the hot melt bonding of cotton swabs, and particularly relates to a hot melt bonding device for the production of dust-free cotton swabs. Background Technique

[0002] At present, dust-free cotton swabs are a widely used product, and the hot melt bonding link in the production process is crucial for production efficiency and product quality. Traditional production methods have problems such as insecure bonding and low production efficiency. To solve these problems, the utility model proposes a brand-new hot melt bonding device for the production of dust-free cotton swabs. The hot melt bonding device includes components such as a base, a left side plate, a right side plate, a dust-free cotton swab conveyor belt, a heat insulation support plate, an electric heating top seat, and a lifting heat shielding plate. Through the heating effect of the electric heating top seat and the transmission of the conveyor belt, the bonding and fixing of the cotton swab and the rod are realized. At the same time, the device also includes a cotton swab regular conveying device, which is used to ensure that the cotton swabs before bonding are correctly placed and stably conveyed to the bonding area.

[0003] However, there are still some deficiencies in the hot melt bonding device for the production of dust-free cotton swabs. When hot melt bonding dust-free cotton swabs, a large number of semi-finished dust-free cotton swabs are placed on the conveyor belt, and then the conveyor belt conveys the semi-finished dust-free cotton swabs to the drying area. The drying area will dry the dust-free cotton swabs, making the bonding on the dust-free cotton swabs solidify, so that the cotton ball can be firmly sleeved and fixed on the outside of one end of the rod. However, because a large number of dust-free cotton swabs are directly placed on the conveyor belt and conveyed to the drying area, some dust-free cotton swabs will stack together, which will affect heat transfer, resulting in the lowest layer of dust-free cotton swabs being heated less and prone to incomplete bonding and hot melting. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] The present utility model provides as Figures 1-3A hot melt bonding device for the production of dust-free cotton swabs as shown, includes a base 5 and a right side plate 10 arranged at the top right end of the base 5. A left side plate 11 is arranged at the top left end of the base 5. A dust-free cotton swab conveyor belt 6 is arranged between the base 5 and the left side plate 11 and the right side plate 10. Heat insulation support plates 9 are arranged at the tops of the left side plate 11 and the right side plate 10. An electric heating top seat 8 is connected to the tops of the two heat insulation support plates 9. Lifting heat shielding plates 7 are arranged at the front, rear, left, and right ends between the electric heating top seat 8 and the two heat insulation support plates 9, and the lifting heat shielding plates 7 can be adjusted up and down. The inside of the lifting heat shielding plates 7 is provided with heat insulation cotton. Electric heating wires are fixed on the inner wall of the top end of the electric heating top seat 8. An electric control box is arranged on the outer wall of the left end of the left side plate 11. The electric heating wires are electrically connected to the electric control box through wires. The top end inner wall of the electric heating top seat 8 is parallel to the outer wall of the top end of the dust-free cotton swab conveyor belt 6. Support columns 1 are arranged at the four corners of the bottom end of the base 5. Strengthening connecting rods 4 are connected between the bottom ends of the multiple support columns 1. The outer walls of the bottom ends of the multiple support columns 1 are on the same horizontal plane. A motor box 3 is arranged at the bottom rear of the base 5. A transmission protection cover 2 is connected between the motor box 3 and the outer wall of the right end of the right side plate 10. A main transmission roller is connected between the rear ends of the left side plate 11 and the right side plate 10. A plurality of driven transmission rollers are equidistantly arranged on the front side of the main transmission roller. The main transmission roller and the plurality of driven transmission rollers are all arranged inside the dust-free cotton swab conveyor belt 6. A motor is arranged inside the motor box 3. The right end of the roller shaft of the main transmission roller and the right end of the output shaft of the motor are both located inside the transmission protection cover 2. Pulley wheels are arranged outside the roller shaft and the right end of the motor output shaft. Transmission belts are connected outside the two pulley wheels. When using this hot melt bonding device for the production of dust-free cotton swabs, first, this hot melt bonding device for the production of dust-free cotton swabs needs to be placed on the workshop floor through the multiple support columns 1. Then, power is connected to the motor inside the motor box 3 and the electric heating wires on the inner wall of the top end of the electric heating top seat 8. Then, the motor inside the motor box 3 and the electric heating wires on the inner wall of the top end of the electric heating top seat 8 need to be started through the electric control box. The electric heating wires can heat up the area between the electric heating top seat 8 and the two heat insulation support plates 9 to the temperature for hot melt processing of dust-free cotton swabs. The motor will drive the main transmission roller through the transmission belt, so that the main transmission roller and the plurality of driven transmission rollers drive the dust-free cotton swab conveyor belt 6 to rotate. Then, the dust-free cotton swabs that need to be hot melt bonded are placed on the dust-free cotton swab conveyor belt 6. At this time, the cotton heads of the dust-free cotton swabs are sleeved on the outside of one end of the rod through glue. When the dust-free cotton swabs are conveyed to the lower side of the electric heating top seat 8, the high temperature in the area between the electric heating top seat 8 and the two heat insulation support plates 9 will dry the glue, so that the cotton heads can be firmly bonded to the outside of one end of the rod. Finally, the hot melt bonded dust-free cotton swabs are conveyed to the tail of the dust-free cotton swab conveyor belt 6 and fall into the collection box.

[0022] As Figure 1 and Figure 3As shown, a cotton swab regular conveying device 12 is provided on the outer wall of the dust-free cotton swab conveyor belt 6. The cotton swab regular conveying device 12 includes heat-resistant soft rubber strips 13, heat-insulating rubber pads 14 and cotton swab regular grooves 15. There are multiple heat-resistant soft rubber strips 13, and the multiple heat-resistant soft rubber strips 13 are equidistantly arranged on the outer wall of the dust-free cotton swab conveyor belt 6. Heat-insulating rubber pads 14 are connected between adjacent heat-resistant soft rubber strips 13. A plurality of inwardly recessed cotton swab regular grooves 15 are equidistantly arranged on the outer wall of the heat-insulating rubber pads 14. The heat-resistant soft rubber strips 13 and the heat-insulating rubber pads 14 are made of the same material. The inner walls of the heat-resistant soft rubber strips 13 and the heat-insulating rubber pads 14 are both fixedly attached to the outer wall of the dust-free cotton swab conveyor belt 6. The heat-resistant soft rubber strips 13 are connected end to end and fixed on the outer wall of the dust-free cotton swab conveyor belt 6. After the cotton head of the dust-free cotton swab is sleeved on the outside of one end of the rod through glue, it is necessary to place the dust-free cotton swab in this state on the dust-free cotton swab conveyor belt 6 and convey it to the hot melt area for glue drying processing. When placing the dust-free cotton swab with wet glue, just place the dust-free cotton swab on the heat-insulating rubber pad 14, and then push the dust-free cotton swab back and forth. At this time, a relatively large number of dust-free cotton swabs will automatically stay in the cotton swab regular grooves 15 on the heat-insulating rubber pad 14, and only one dust-free cotton swab will stay in each cotton swab regular groove 15. Therefore, after a plurality of dust-free cotton swabs are placed on the heat-insulating rubber pad 14, they can be regularly placed. Moreover, the heat-resistant soft rubber strips 13 on both sides of the heat-insulating rubber pad 14 can prevent the dust-free cotton swabs from falling to one side, ensuring that the dust-free cotton swabs can stably stay on the heat-insulating rubber pad 14. In this way, the dust-free cotton swab conveyor belt 6 can convey the regular dust-free cotton swabs to the lower side of the electric heating top seat 8 for hot melt bonding processing.

[0023] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
