Description

Technical Field

[0001] This utility model relates to the field of footwear processing technology, and in particular to a glue spraying device for rain boot production. Background Technology

[0002] Rain boots are waterproof shoes worn in the rain. Most rain boots are made of rubber. In the final step of rain boot production, adhesive is sprayed onto the surface of the boots to improve their aging resistance and extend their service life. When spraying adhesive, the rain boots need to be inserted into a fixing bracket for fixation. However, the fixing brackets in most adhesive spraying devices are generally fixed structures that can only be used to fix one type of rain boot, which limits their use.

[0003] For example, a Chinese patent document discloses a glue spraying device for rain boot production (publication number: CN221492919U). This patent uses an L-shaped support rod to squeeze the L-shaped support rod towards the fixed rod, and then puts the rain boot that needs to be sprayed with glue on the outside of the fixing mechanism. After the rain boot is completely on the outside of the fixing mechanism, the L-shaped support rod is released, so that the L-shaped support rod and the fixed rod together support and fix the rain boot. The L-shaped support rod is connected to the fixed rod by three springs, so that the fixing mechanism can fix different models and types of rain boots.

[0004] However, during the glue spraying process, workers need to wait for the spraying to finish before they can remove the rain boots and replace them with new ones. This means that the equipment is in a stopped state every time the rain boots are changed. The accumulation of this downtime causes the overall production process to be interrupted, making it impossible to achieve continuous and efficient production, which seriously reduces production efficiency. In addition, the support plate has an open structure, and when the glue spraying operation is performed, the glue is easy to splash into the space around the support plate, making it difficult to collect and collect the splashed glue. This not only wastes glue and increases production costs, but also makes the working environment dirty and messy. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the tendency of glue to splatter everywhere during the spraying process, making it difficult to recycle, and the long downtime of the machine when changing rain boots, which seriously reduces production efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A glue spraying device for producing rain boots includes a material cylinder, and a rotation switching mechanism is provided above the material cylinder;

[0008] The rotation switching mechanism includes an open protective cover, the lower end of which is fixedly connected to the upper end of the material cylinder. A drive rod is rotatably connected to the inner wall of the upper end of the open protective cover via a bearing. A baffle arranged in a circular array is fixedly connected to the outside of the drive rod. An mounting plate is fixedly connected between two adjacent baffles. A rotating rod is rotatably connected to the inner wall of the mounting plate via a bearing. A driven gear is fixedly sleeved on the upper end of the rotating rod.

[0009] The material cylinder is equipped with a glue spraying mechanism on its exterior.

[0010] Preferably, the rotating rod is externally fixedly connected to a telescopic rod arranged in a linear array, and one end of each of the multiple telescopic rods is fixedly connected to a support mold, and one side of the support mold is fixedly connected to a support spring arranged in a linear array.

[0011] Preferably, one end of each of the plurality of support springs is fixedly connected to the outside of the rotating rod, and a first servo motor is fixedly installed at the upper end of the opening protective cover. The output shaft of the first servo motor is fixedly installed with a first rotating shaft through a coupling.

[0012] Preferably, one end of the first rotating shaft extends into the interior of the opening protective cover and is fixedly fitted with a drive gear, the tooth surface of the drive gear meshing with the tooth surface of one of the driven gears.

[0013] Preferably, a drive wheel is fixedly sleeved on the upper end of the drive rod, and an arc-shaped limiting groove and a drive groove are respectively opened on the outside of the drive wheel in a ring array. A second servo motor is fixedly installed on the upper end of the opening protective cover, and a second rotating shaft is fixedly installed on the output shaft of the second servo motor through a coupling.

[0014] Preferably, a turntable and an arc-shaped limiting block are fixedly sleeved on the outside of the second rotating shaft, a lever is fixedly connected to the upper end of the turntable, and the outer surface of the arc-shaped limiting block contacts the inner wall of one of the arc-shaped limiting grooves.

[0015] Preferably, the glue spraying mechanism includes a pressure pump, one side of which is fixedly installed to the outside of the material cylinder, and the upper end of the pressure pump is fixedly connected to a delivery pipe. One end of the delivery pipe passes through the inner wall of the opening protective cover and is fixedly connected to a flow divider block. One side of the flow divider block is fixedly connected to the inner wall of the opening protective cover, and the other side of the flow divider block is fixedly installed with nozzles arranged in a linear array.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] In this invention, the combined use of the rotation switching mechanism and the glue spraying mechanism enables automatic switching of workstations. Glue spraying and loading / unloading can be carried out simultaneously without machine downtime, significantly shortening the glue spraying cycle for a single pair of rain boots and greatly improving overall production efficiency. Furthermore, the glue splashed during spraying is intercepted by the baffle and flows back into the material cylinder, achieving glue recycling and reuse, reducing material waste, maintaining a clean working environment, and reducing cleaning costs. Moreover, the rain boots rotate at a uniform speed during glue spraying, and the nozzle sprays glue evenly, ensuring consistent glue thickness on the surface of the rain boots without any missed areas, thus improving product quality.

[0030] Example

[0031] like Figure 1-7 As shown, this utility model provides a technical solution: a glue spraying device for rain boot production, including a material cylinder 1, a rotation switching mechanism, and a glue spraying mechanism. The various parts cooperate with each other to complete the processes of rain boot clamping, station switching, glue spraying, and glue recycling.

[0032] The material cylinder 1 serves as the basic component for glue storage and recycling. Its upper end is fixedly connected to the lower end of the opening protective cover 2 by welding or bolting. The opening protective cover 2 provides switching space for the rotation switching mechanism and realizes the glue recycling function with the help of the baffle 22.

[0033] The upper end of the drive rod 21 is rotatably connected to the inner wall of the upper end of the opening protective cover 2 via a bearing to ensure smooth rotation. The drive rod 21 is fixedly connected to the outside of the baffles 22 arranged in a ring array by welding or other means. The mounting plates 23 are welded between adjacent baffles 22. The inner wall of the mounting plate 23 is rotatably connected to the rotating rod 24 via a bearing. The upper end of the rotating rod 24 is fixedly sleeved with the driven gear 25 by key connection or other means.

[0034] The rotating rod 24 is fixedly connected to the outside of the telescopic rods 26 arranged in a linear array by welding or other means. One end of the telescopic rods 26 is fixedly connected to the support mold 27 by bolts or other means. Support springs 28 arranged in a linear array are welded to one side of the support mold 27. The other end of the support springs 28 is welded to the outside of the rotating rod 24 to achieve elastic adaptation and clamping for different models of rain boots.

[0035] The first servo motor 29 is fixedly installed on the upper end of the opening protective cover 2 by screws. Its output shaft is fixedly connected to the first rotating shaft 210 by a coupling. One end of the first rotating shaft 210 passes through the inside of the opening protective cover 2 and is fixedly connected to the drive gear 211 by a key. The tooth surface of the drive gear 211 can mesh with the tooth surface of the driven gear 25 to transmit rotational power.

[0036] The upper end of the drive rod 21 is fixedly connected to the drive wheel 212 by a key. The drive wheel 212 has arc-shaped limiting grooves 213 and drive grooves 214 arranged in a ring array on its outer side. The upper end of the opening protective cover 2 is fixedly installed with the second servo motor 215 by screws. Its output shaft is fixedly connected to the second rotating shaft 216 by a coupling.

[0037] The second rotating shaft 216 is externally connected by a key, and the rotating disk 217 and the arc-shaped limiting block 218 are fixedly sleeved together. The upper end of the rotating disk 217 is welded with a lever 219. The outer surface of the arc-shaped limiting block 218 is adapted to contact the inner wall of the arc-shaped limiting groove 213 to achieve precise switching of work positions.

[0038] In the glue spraying mechanism, the pressure pump 3 is connected to the outside of the material cylinder 1 by means of screw fixing or other methods. The upper end of the pressure pump 3 is fixedly connected to the conveying pipe 31 by means of welding or threaded connection or other methods. One end of the conveying pipe 31 passes through the inner wall of the open protective cover 2 and is fixedly connected to the diverter block 32 by means of welding or threaded connection or other methods.

[0039] One side of the diverter block 32 is welded and fixed to the inner wall of the opening protective cover 2, and the other side is fixed with screws and other means to install nozzles 33 arranged in a linear array to realize the delivery and atomization of glue.

[0040] The working process of this utility model:

[0041] Step 1: Based on the size of the rain boots, manually compress the telescopic rod 26. The support spring 28 adaptively adjusts the position of the support mold 27 so that the support mold 27 fits against the inner wall of the rain boot, completing the fixed clamping of the rain boots and preparing for continuous production. The second servo motor 215 starts, and the output shaft drives the second rotating shaft 216 to rotate, synchronously driving the turntable 217 and the arc-shaped limit block 218 to rotate. The lever 219 on the turntable 217 is embedded in the drive groove 214 of the drive rod 21. As the turntable 217 rotates, the lever 219 pushes the drive rod 21 to rotate. The arc-shaped limit block 218 cooperates with the arc-shaped limit groove 213 to ensure that for every rotation of the turntable 217, the drive rod 21 rotates 90 degrees to switch work positions.

[0042] Step two: When the mounting plate 23 drives the rain boot to switch to the glue spraying station, the driven gear 25 meshes with the driving gear 211, the first servo motor 29 starts, and the output shaft drives the first rotating shaft 210 to rotate. The driving gear 211 rotates accordingly. Through gear meshing, the driven gear 25, the rotating rod 24 and the rain boot rotate at a uniform speed. At the same time, the pressure pump 3 works, and the glue in the material cylinder 1 is transported to the nozzle 33 through the conveying pipe 31 and the diverting block 32. After atomization, it is evenly sprayed on the surface of the rotating rain boot, achieving comprehensive and uniform glue spraying. During the glue spraying process, the splashed glue is blocked by the baffle 22 inside the opening protective cover 2 and falls back into the material cylinder 1 along the baffle 22, completing the glue recycling. After the glue spraying is completed, the second servo motor 215 drives the station switch again. The glued rain boots are rotated to the upper and lower material positions for unloading, and the new rain boots are rotated to the glue spraying position to enter the next glue spraying cycle, continuously realizing continuous production.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
