Description

Technical Field

[0001] This application relates to the field of glove manufacturing technology, and in particular to an automatic glue-applying device for glove manufacturing. Background Technology

[0002] Currently available gloves need to improve their heat resistance and insulation properties, and work gloves require automatic gluing during production. Chinese patent CN218835033U discloses an automatic gluing device for work glove production, comprising a frame, a rotating device installed within the frame, a gluing device installed within the frame, and a glove fitted onto the rotating device. The rotating device includes a bearing, a servo motor, and a glove last. The bearing is installed within the frame, the servo motor is mounted on the frame, the output shaft of the servo motor is installed within the inner ring of the bearing, the output shaft of the servo motor extends into the frame, the glove last is mounted on the output shaft of the servo motor, and the glove is fitted onto the glove last. Compared with traditional technology, this automatic glue-applying device for the production of work gloves has the following advantages: when the glove is placed on the glove last, the glove last can support the glove and make its surface rounded, so that it will not deform during glue application. As the glove rotates, an external air pump pressurizes the glue tank through a hose, and the glue in the glue tank is sprayed out through the nozzle and sprayed onto the surface of the glove to perform the glue application.

[0003] In the prior art, after the adhesive is sprayed onto the surface of the gloves, it is generally necessary to dry them to accelerate the drying of the coating. The drying box in the prior art transfers heat energy through thermal radiation from top to bottom, so the inside of the glove last receives less heat, which reduces the drying effect. Utility Model Content

[0004] In order to overcome the problems existing in the prior art, this application provides an automatic glue-applying device for glove production.

[0005] The automatic gluing device for glove production provided in this application adopts the following technical solution:

[0006] An automatic glove-applying device for glove production includes a frame, within which an electric turntable is installed. The turntable has a circumferential array of several sets of glove lasts for glove assembly. A spraying mechanism and a drying mechanism are respectively installed on the inner walls of both sides of the frame. A conductive mechanism for energizing the glove lasts is also installed on the inner wall of the frame near the drying mechanism. Heating resistors are evenly distributed on the surface of the glove lasts. The electric turntable is driven by a first motor and also has a central gear and planetary gears arranged in a ring around the central gear. The system includes a central gear driven by a second motor, planetary gears mounted at the ends of the glove last, a spraying mechanism comprising a spray nozzle and a glue tank connected to the spray nozzle via a hose, wherein a glue pump connected to the hose is installed inside the glue tank, and the spray nozzle moves up and down on the inner wall of the frame; and a drying mechanism comprising a heating box mounted on the outer side of the frame, wherein the heating box is connected to an air pump via a pipe, and the air outlet of the air pump is connected to the drying surface on the inner side of the frame, wherein several sets of air outlets are provided on the drying surface, and the height of the air outlets is adapted to the height of the glove.

[0007] By adopting the above technical solution, a glove last for glove assembly is installed on the electric turntable within the frame. Driven by a first motor, the electric turntable rotates the gloves between the spraying mechanism and the drying mechanism, enabling continuous operation of glove spraying and drying. The spraying mechanism uses a glue pump located in the glue tank to spray glue onto the gloves on the glove last through nozzles. The drying mechanism generates high-temperature gas in a heating chamber, which is then extracted through pipes by a vacuum pump and dried on a drying surface on the vacuum pump's outlet pipe. Several sets of air outlets on the drying surface are adapted to the height of the gloves, ensuring thorough drying of the glue on the outer surface. Simultaneously, a conductive mechanism installed on the side of the electric turntable near the drying mechanism contacts the corresponding glove last on the turntable, energizing the heating resistor on the surface of the corresponding glove last to heat the inner side of the glove, thus improving the drying effect on the inner side of the glove. During the glove spraying and drying process on the glove last, the second motor drives the central gear of the electric turntable to rotate. The central gear drives the planetary gears around it to rotate, thereby rotating the glove during spraying and drying and improving the uniformity of automatic glue application.

[0008] Preferably, the bottom of the planetary gear in the electric turntable is detachably connected to the glove last, wherein the connecting protrusion at the bottom center of the planetary gear engages with the connecting groove at the top of the glove last, and a bolt is installed on the connecting groove to limit the connection protrusion.

[0009] Preferably, one end of the glove last located in the connecting groove is made of a conductor, which is connected to a heating resistor on the surface of the glove last, and the conductor is in contact with the conductive mechanism.

[0010] Preferably, the conductive mechanism includes an arc-shaped conductive strip installed on the side wall of the frame, wherein the end of the arc-shaped conductive strip is connected to an external AC power source via an electric wire, and the side of the arc-shaped conductive strip closest to the inner wall of the frame is connected to the frame via a spring, and an insulating sleeve is fitted on the spring.

[0011] By adopting the above technical solution, the connecting protrusion at the bottom of the planetary gear mates with the connecting groove at the top of the glove last, and the two are fixedly connected by bolts on the connecting groove, facilitating disassembly and maintenance of the glove last after use. The conductor at the top of the glove last is used to connect the heating resistor on the surface of the glove last and the conductive mechanism. The conductive mechanism connects the arc-shaped conductive strip to the conductor under the action of a spring, and supplies power to the heating resistor on the surface of the glove last through an external AC current, thereby achieving the drying of the glove lining.

[0012] Preferably, the nozzle includes a body and a bracket, wherein a hose is connected to the top of the body, and the bracket is longitudinally distributed on the inner side wall of the frame. A strip-shaped through groove is formed on the bracket along its length direction, and an adjusting gear is installed in the strip-shaped through groove. The adjusting gear meshes with a rack at the end of the body and is driven by a servo motor.

[0013] Preferably, the two ends of the bracket are connected to the top plate and bottom plate of the frame, respectively, and the range of motion of the main body is adapted to the height of the glove last.

[0014] By adopting the above technical solution, the adjusting gear on the bracket in the nozzle is driven by a servo motor. The adjusting gear meshes with the rack on the main body, thereby driving the main body of the nozzle to move up and down on the longitudinally distributed bracket, so as to evenly spray glue onto the glove surface of the glove, ensuring the uniformity of glue application on the glove. The two ends of the bracket are connected to the top and bottom of the frame respectively to prevent the main body of the nozzle from slipping out. The movement of the main body is adapted to the height of the glove last, so that the glove surface can be fully coated with glue.

[0015] Preferably, the drying surface has an arc-shaped structure, and the air outlet on the side of the drying surface facing the glove faces the center of the arc.

[0016] Preferably, the air inlet of the heating chamber is located at the end away from the air pump, and a filter plate is installed on the air inlet.

[0017] By adopting the above technical solution, the arc-shaped structure of the drying surface can concentrate the heat discharged from the air inlet, efficiently drying the adhesive on the glove surface. Furthermore, a filter plate is installed at the air inlet of the heating chamber to reduce impurities entering the heating chamber, thus minimizing their impact on the normal operation of the heating chamber and the drying of the adhesive on the gloves.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. This application uses a drying mechanism to fully dry the glue on the outer surface of the glove. A conductive mechanism installed on one side of the drying mechanism can contact the corresponding glove last on the electric turntable, energize the heating resistor on the surface of the glove last, and heat the inner side of the glove, thereby improving the overall drying effect of the glove.

[0020] 2. In the process of glove spraying and drying on the glove last, the rotation of the planetary gear drives the rotation of the glove last, thereby rotating the glove during the spraying and drying process and improving the uniformity of automatic glue application.

[0026] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0027] This application discloses an automatic glue-applying device for glove production.

[0028] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4An automatic glove-applying device for glove production includes a frame 1, an electric turntable 2 installed inside the frame 1, a plurality of glove lasts 3 arranged in a circular array on the electric turntable 2 for glove fitting, and a spraying mechanism 4 and a drying mechanism 5 respectively installed on the inner walls of both sides of the frame 1. A conductive mechanism 6 for energizing the glove lasts 3 is also installed on the inner wall of the frame 1 near the drying mechanism 5 of the electric turntable 2, and heating resistors are evenly distributed on the surface of the glove lasts 3. The electric turntable 2 is driven by a first motor 21, and a central gear 22 and planetary gears 23 arranged in a ring around the central gear 22 are also installed on the electric turntable 2. The central gear 22 is driven by a second motor 21. A motor 221 drives a planetary gear 23 mounted on the end of the glove last 3. A spraying mechanism 4 includes a nozzle 41 and a glue tank 42 connected to the nozzle 41 via a hose 413. A glue pump 421 connected to the hose 413 is installed inside the glue tank 42. The nozzle 41 moves up and down on the inner wall of the frame 1. A drying mechanism 5 includes a heating box 51 installed on the outside of the frame 1. The heating box 51 is connected to an air pump 52 via a pipe. The air outlet of the air pump 52 is connected to a drying surface 53 inside the frame 1. The drying surface 53 has several sets of air outlets 531, the height of which is adapted to the height of the gloves. A glove last 3 for glove fitting is mounted on an electric turntable 2 inside the frame 1. Driven by the first motor 21, the electric turntable 2 can rotate the gloves between the spraying mechanism 4 and the drying mechanism 5, achieving continuous glue spraying and drying of the gloves. The spraying mechanism 4 uses a glue pump 421 located on the glue tank 42 to spray glue onto the gloves on the glove last 3 through the nozzle 41. The drying mechanism 5 generates high-temperature gas through the heating chamber 51, and the high-temperature gas is extracted through the pipe by the vacuum pump 52. The glued gloves are dried through the drying surface 53 on the exhaust pipe of the vacuum pump 52. The several sets of air outlets 531 on the drying surface 53 are adapted to the height of the gloves, which can fully dry the glue on the outer surface of the gloves. At the same time, the conductive mechanism 6 installed on the side of the electric turntable 2 near the drying mechanism 5 can contact the corresponding glove last 3 on the electric turntable 2, thereby energizing the heating resistor on the surface of the corresponding glove last 3, heating the inner side of the gloves, and improving the drying effect of the inner side of the gloves. During the glove spraying and drying process on the glove last 3, the second motor 221 drives the central gear 22 in the center of the electric turntable 2 to rotate. The central gear 22 drives the planetary gears 23 around it to rotate, thereby rotating the glove during spraying and drying and improving the uniformity of automatic glue application to the glove.

[0029] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The planetary gear 23 in the electric turntable 2 is detachably connected to the glove last 3. A connecting protrusion 231 at the bottom center of the planetary gear 23 engages with a connecting groove 31 at the top of the glove last 3, and a bolt 311 is installed on the connecting groove 31 to limit the position of the connecting protrusion 231. One end of the glove last 3 located in the connecting groove 31 is a conductor, connected to a heating resistor on the surface of the glove last 3, and in contact with the conductive mechanism 6. The conductive mechanism 6 includes an arc-shaped conductive strip 61 mounted on the side wall of the frame 1. The end of the arc-shaped conductive strip 61 is connected to AC power via an external wire. The side of the arc-shaped conductive strip 61 closest to the inner wall of the frame 1 is connected to the frame 1 via a spring 62, and an insulating sleeve is fitted onto the spring 62. The connecting protrusion 231 at the bottom of the planetary gear 23 mates with the connecting groove 31 at the top of the glove last 3, and the two are fixedly connected by the bolt 311 on the connecting groove 31, facilitating the disassembly and maintenance of the glove last 3 later. The conductor at the top of the glove last 3 is used to connect the heating resistor on the surface of the glove last 3 and the conductive mechanism 6. The conductive mechanism 6 connects the arc-shaped conductive strip 61 to the conductor under the action of the spring 62. The heating resistor on the surface of the glove last 3 is powered by an external AC power supply to achieve the drying of the inside of the glove.

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The nozzle 41 includes a main body 411 and a bracket 412. The top of the main body 411 is connected to a flexible hose 413. The bracket 412 is longitudinally distributed on the inner wall of the frame 1. A strip-shaped through groove 4121 is formed on the bracket 412 along its length, and an adjusting gear 4122 is installed in the strip-shaped through groove 4121. The adjusting gear 4122 meshes with a rack 4111 at the end of the main body 411 and is driven by a servo motor 4123. The two ends of the bracket 412 are connected to the top plate and the bottom plate of the frame 1, respectively, and the range of motion of the main body 411 is adapted to the height of the glove last 3. The adjusting gear 4122 on the bracket 412 in the nozzle 41 is driven by the servo motor 4123. The adjusting gear 4122 meshes with the rack 4111 on the main body 411, thereby driving the main body 411 of the nozzle 41 to move up and down on the longitudinally distributed bracket 412, so as to evenly spray glue onto the glove on the surface of the glove last 3, ensuring the uniformity of glue application. The two ends of the bracket 412 are connected to the top and bottom of the frame 1 respectively to prevent the main body 411 of the nozzle 41 from slipping out. The movement of the main body 411 is adapted to the height of the glove last 3, so that the glove surface can be fully coated with glue.

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4The drying surface 53 has an arc-shaped structure, and the air outlet 531 on the side of the drying surface 53 facing the glove points towards the center of the arc. The air inlet 511 of the heating chamber 51 is located at the end away from the suction pump 52, and a filter plate 512 is installed on the air inlet 511. The arc-shaped structure of the drying surface 53 can concentrate the heat discharged from the air inlet 511, efficiently drying the adhesive on the glove surface. Furthermore, the filter plate 512 installed at the air inlet 511 of the heating chamber 51 can reduce impurities entering the heating chamber 51, which could affect the normal operation of the heating chamber 51 and the drying of the adhesive on the glove.

[0032] Working principle: First, gloves to be coated are placed on the glove lasts 3 of the electric turntable 2 inside the frame 1. The gloves are rotated by the electric turntable 2 and enter the spraying mechanism 4 for coating. The nozzle 41 in the spraying mechanism 4 moves up and down and, in coordination with the rotation of the glove lasts 3, sprays the coating evenly on the surface of the gloves. After the coating is completed, the electric turntable 2 rotates the glove lasts 3 to the drying mechanism 5. At this time, the drying mechanism 5 vents hot air through the air outlet 531 on the drying surface 53 to dry the outer surface of the gloves. The top of the glove lasts 3 is energized by the arc-shaped conductive adjustment contact of the conductive mechanism 6, which heats the heating resistor on the surface of the glove lasts 3, thereby heating the inside of the gloves. After drying is completed, the gloves are removed from the glove lasts 3 on the electric turntable 2.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
