Description

Technical Field

[0001] This utility model relates to the field of slipper processing technology, and more specifically, to a slipper dipping and coating machine. Background Technology

[0002] Slippers are essential lightweight footwear for both home and leisure, made from soft materials such as EVA, PVC, or rubber, prioritizing comfort and slip resistance. They come in a variety of designs, including flip-flops, clogs, and single-strap sandals, catering to different needs. The production process typically involves injection molding, cutting, and assembly; some styles utilize water transfer printing to add patterns and enhance their aesthetics. Slippers are breathable, easy to put on and take off, and water-resistant, making them widely used in bathrooms, on the beach, and at home—a practical and stylish item.

[0003] In the current water transfer printing process for slippers, manual hand-held operation is commonly used, where workers directly place the slippers into the water transfer tank for pattern transfer. This method has significant drawbacks: First, it relies entirely on the operator's experience to control the angle and depth of the slippers entering the water, making it difficult to ensure consistent transfer results for each pair. Second, manual operation is unstable, easily leading to pattern misalignment or incomplete transfer due to shaking or uneven pressure. Third, prolonged repetitive work easily causes worker fatigue, affecting production efficiency and potentially causing product scrap due to operational errors. Furthermore, manual operation poses safety hazards, as workers are in close contact with chemical activators, which may impact their health. This traditional process can no longer meet the higher requirements of modern production for quality stability and efficiency, and urgently needs to be upgraded through automated equipment. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the problems existing in the prior art, this utility model provides a slipper dip coating machine to solve the technical problem mentioned in the background art where the slipper dip coating machine has poor stability due to manual operation.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A slipper dipping coating machine includes a water transfer printing tank. A mounting frame is mounted on the top of the water transfer printing tank. A drive shaft is mounted on the mounting frame, and a drive motor is mounted in conjunction with the drive shaft. Two sets of drive wheels are symmetrically arranged on the drive shaft, and each set of drive wheels is equipped with a drive belt. The drive motor controls the drive shaft to rotate the drive wheels, thereby moving the drive belt. Multiple mounting seats are evenly arranged on the outer sides of the two sets of drive belts. A first support frame and a second support frame are mounted on the mounting frame. The first support frame is located at the front end of the mounting frame and is equipped with a glue spraying assembly. The second support frame is located at the rear of the mounting frame and is equipped with a primer spraying assembly. A water transfer paint spraying structure is located behind the water transfer printing tank. A water transfer paint guiding structure is provided inside the water transfer printing tank. A partition plate is provided on the drive belt located between the two sets of mounting seats.

[0009] The present invention is further configured such that the glue spraying assembly includes a glue spraying tube, on which a plurality of glue spraying heads are evenly arranged; a glue supply assembly is connected to the glue spraying tube; the glue supply assembly includes a glue storage tank; a first pump body is provided on the glue storage tank; a glue supply pipe is provided between the output end of the first pump body and the glue spraying tube; when the first pump body is activated, liquid glue in the glue storage tank can be extracted under the action of the first pump body and delivered to the glue spraying tube through the glue supply pipe; and then evenly sprayed onto the corresponding mounting base through the glue spraying heads on the glue spraying tube. During the water transfer printing process of slippers, this temporary adhesive can be used to fix the slippers to the mounting base, so that the slippers can move with the drive belt, thereby realizing the automatic water transfer printing operation of slippers.

[0010] The present invention is further configured such that the primer spraying assembly includes a spray pipe, a plurality of spray nozzles are evenly arranged on the spray pipe, and a paint supply assembly is connected to the spray pipe.

[0011] The present invention is further configured such that the paint supply assembly includes a paint storage tank, a second pump body is provided on the paint storage tank, and a paint supply pipe is provided between the output end of the second pump body and the paint spraying pipe. When the second pump body is started, the primer paint in the paint storage tank is extracted and transported to the paint spraying pipe through the paint supply pipe. The primer paint is then evenly sprayed out through the spray nozzle on the paint spraying pipe, so that the surface of the slipper can be coated with primer before water transfer printing is performed. This improves the adhesion performance of the water transfer printing paint on the surface of the slipper.

[0012] The present invention is further configured such that the water transfer printing paint spraying structure includes a spray head, a spray frame is provided on the water transfer printing tank, a movable adjustment structure is provided between the spray head and the spray frame, and a spray supply component is connected to the spray head.

[0013] The present invention is further configured such that the spraying supply component includes a storage tank, a third pump body is provided on the storage tank, and a spraying hose is provided between the output end of the third pump body and the spraying head. When the third pump body is started, the water transfer printing paint in the storage tank can be extracted under the action of the third pump body and transported to the spraying head through the spraying hose to realize the spraying operation of the water transfer printing paint in the water transfer printing tank.

[0014] The present invention is further configured such that the movable adjustment structure includes a ball screw, the ball screw is mounted on the spraying frame, and a screw motor and a screw nut are provided in conjunction with the ball screw. The spraying head is mounted on the screw nut. When the screw motor controls the ball screw to run, the screw nut will drive the spraying head to move on the water transfer tank, thereby realizing flexible adjustment when the water transfer ink is sprayed into the water transfer tank.

[0015] The present invention is further configured such that the water transfer printing paint guiding structure includes a guide shaft, the guide shaft is disposed in the water transfer printing tank through a sealed bearing, two sets of guide wheels are symmetrically arranged on the guide shaft, and a guide chain is disposed between each set of guide wheels. A guide motor is disposed on the outside of the water transfer printing tank in conjunction with the guide shaft. When the guide motor is started, the guide shaft can be controlled to drive the guide wheels to rotate, and the rotation of the guide wheels drives the rotation of the guide chain, thereby realizing the movement and conveying of the water transfer printing paint in the water transfer printing tank. This allows the paint required for the water transfer printing of slippers to move forward synchronously or approximately synchronously with the slippers, achieving a one-to-one correspondence.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a slipper dipping coating machine, which has the following beneficial effects:

[0018] 1. This utility model, through the setting of a drive belt and mounting base, etc., allows the drive motor to control the movement of the drive belt, thereby realizing the movement of the mounting base and partition plate located on the drive belt. First, a temporary adhesive (such as low-viscosity hot melt adhesive or special water transfer printing adhesive) is sprayed onto the corresponding mounting base through the cooperation of the spray tube and the spray head. Then, the bottom of the slipper to be water-transfer printed is glued to the mounting base and moves with the drive belt. When it moves to the position of the spray tube, the spray tube and the spray head can spray the primer on the surface of the slipper before water transfer printing. Afterwards, the drive belt drives the slipper with the primer sprayed to move and flip, so that the slipper can be stably flipped and immersed in the water transfer printing tank, contacting the water transfer printing paint in the water transfer printing tank to achieve immersion printing. In this way, manual intervention can be reduced, and the stability and efficiency are high during the water transfer printing process of the slipper.

[0019] 2. This utility model provides a partition plate between two adjacent mounting seats, so that when the drive belt moves the moving seat, it can move the partition plate synchronously. After the previous group of slippers is dipped and coated, the partition plate will be immersed in the water transfer printing tank to separate the previous group of slippers from the subsequent water transfer printing paint, thus ensuring the water transfer printing effect of the subsequent slippers.

[0020] 3. This utility model includes a water transfer printing paint spraying structure and a water transfer printing paint guiding structure. In the above process, the water transfer printing paint can be sprayed onto the water surface in the water transfer tank through the cooperation of the spraying pipe and the spraying head to form a water transfer printing pattern. At the same time, the guide motor is started, which controls the guide shaft to drive the guide wheel to rotate. The rotation of the guide wheel drives the movement of the guide chain, thereby guiding the water transfer printing pattern formed on the water surface in the water transfer tank. This realizes the movement and transportation of the water transfer printing paint in the water transfer tank, so that the paint required for the water transfer printing of slippers can move forward synchronously or roughly synchronously with the slippers, achieving a one-to-one correspondence.
