Description

Technical Field

[0001] This utility model belongs to the field of shoe manufacturing equipment technology, specifically a waterproofing agent application device for casual shoe production. Background Technology

[0002] With the continuous development of the footwear industry, the demand for waterproofing agent application devices in the production of casual shoes is increasing. However, existing application devices still have many shortcomings in practical applications, especially in terms of uniform application on complex surfaces, ease of operation, and waterproofing agent utilization.

[0003] A search revealed a coating device with publication number CN109382271B, published on July 10, 2020. This design utilizes the cooperation of a rotating component and a coating component, employing the relative rotation of a first and second scraper with a harmonic reducer to achieve uniform grease application. While this structure effectively coats the grease evenly and improves the surface appearance, it is primarily suitable for coating flat or regular surfaces. Its ability to handle irregular curved surfaces (such as shoe uppers and sole edges) commonly found in casual shoe production is limited, and it struggles to adapt to complex three-dimensional structures. Furthermore, the device lacks a quantitative control function for the waterproofing agent, which may lead to wasted waterproofing agent or uneven application in practical use.

[0004] A search revealed a coating device with publication number CN114887828B, published on April 2, 2024. This design employs a spray nozzle combined with an airbag plate, enabling adaptive dosage adjustment based on the viscosity of the viscous fluid material. Automatic coating is achieved through a reciprocating motion mechanism and a lifting mechanism. While this design improves coating efficiency and uniformity to some extent, it is primarily suitable for coating the end faces of flat workpieces and must avoid specific areas such as screw holes. For the waterproofing needs of casual shoe production, which requires covering various materials and shapes, this device lacks a targeted design and may not meet the high waterproofing requirements of footwear products. Furthermore, its complex multi-mechanism linkage design increases equipment cost and maintenance difficulty, hindering large-scale application.

[0005] The aforementioned problems indicate that existing coating devices still suffer from insufficient coating uniformity, poor applicability, and complex operation when facing the specific needs of casual shoe production. Therefore, this invention provides a waterproofing agent coating device for casual shoe production to overcome these shortcomings and achieve an efficient, precise, and highly adaptable waterproofing agent coating solution. Utility Model Content

[0006] This utility model relates to a waterproofing agent application device for casual shoe production, comprising a base, a coating assembly, an adaptability adjustment assembly, and a metering delivery assembly. The coating assembly is mounted on the top of the base, an adaptability adjustment assembly is connected to one side of the coating assembly, and the metering delivery assembly is disposed inside the base.

[0007] The coating assembly includes a coating head, a flexible coating sheet, elastic pressure strips, a coating cavity, and guide grooves. The coating head is fixed to the front end of the coating assembly via a threaded connection. A flexible coating sheet is located at the bottom of the coating head, and elastic pressure strips are symmetrically fixed to both sides of the flexible coating sheet. A coating cavity is formed inside the coating head, and guide grooves are evenly distributed at the bottom of the coating cavity. The rear end of the coating head is connected to the output end of a metering delivery assembly via a pipe, and a sealing ring is provided on the inner wall of the pipe to prevent liquid leakage.

[0008] The adaptive adjustment assembly includes an adjustment rod, a sliding block, a guide rail, an adjustment motor, and an eccentric wheel. One end of the adjustment rod is hinged to the top of the coating head, and the other end is fixedly connected to the sliding block. The sliding block is slidably connected to the inner wall of the guide rail, which is fixedly installed on the top of the base. An eccentric wheel is attached to one side of the sliding block, and the central shaft of the eccentric wheel is connected to the output shaft of the adjustment motor via a coupling. The adjustment motor is fixed to the top of the base with bolts.

[0009] The quantitative delivery assembly includes a storage tank, a metering pump, a flow sensor, a delivery pipe, and a control module. The storage tank is fixed inside the base by welding. The bottom of the storage tank is connected to the metering pump via a flange. The output end of the metering pump is connected to the rear end of the coating head via the delivery pipe. A flow sensor is installed on the outer wall of the delivery pipe. The flow sensor is connected to the control module via a signal line. The control module is fixed to the side wall of the base by screws.

[0010] The flexible coating sheet of the coating head is made of a polymer material with a microporous surface, which can evenly distribute the waterproofing agent to the surface to be treated through capillary action. The elastic pressure strip is made of spring steel, and its two ends are fixed to both sides of the coating head with screws. During the coating process, it can automatically adjust the pressure according to the curvature of the contact surface, thereby achieving a tight fit to complex surfaces. The width and depth of the guide groove are optimized to ensure that the flow rate of the waterproofing agent in the coating chamber is consistent, avoiding uneven coating caused by differences in flow rate.

[0011] The adaptive adjustment component drives an eccentric wheel to rotate via an adjustable motor, causing the sliding block to reciprocate along the guide rail, thereby adjusting the position of the coating head in the vertical direction. The eccentricity of the eccentric wheel can be adjusted according to actual needs to change the range of motion of the coating head. A lubricating coating is provided on the inner wall of the guide rail to reduce frictional resistance of the sliding block during movement and improve adjustment accuracy.

[0012] The metering delivery assembly uses a metering pump to deliver the waterproofing agent from the storage tank to the coating head at a set flow rate. A flow sensor monitors the liquid flow rate in the delivery pipe in real time and transmits the data to the control module. Based on the data from the flow sensor, the control module dynamically adjusts the operating parameters of the metering pump, thereby achieving precise supply of the waterproofing agent.

[0013] This invention solves the problem of adapting to complex curved surfaces in existing technologies by combining a flexible coating sheet and an elastic pressure strip in the coating assembly, enabling the device to uniformly coat irregular surfaces such as shoe uppers and sole edges. The adaptability adjustment assembly, through the linkage design of an eccentric wheel and a sliding block, achieves automatic height adjustment of the coating head, further enhancing the device's applicability. The quantitative delivery assembly, through the coordinated operation of a metering pump and a flow sensor, avoids waste of waterproofing agent or uneven application, significantly improving resource utilization.

[0014] This invention provides an efficient, precise, and highly adaptable waterproofing agent application solution through optimized design of the coating component, adaptability adjustment component, and quantitative delivery component. It meets the processing needs of various materials and complex shapes in casual shoe production, while reducing equipment costs and maintenance difficulty. It has high practical value and promising prospects for promotion. Attached Figure Description

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Specific implementation examples are given below.

[0022] This utility model relates to a waterproofing agent application device for casual shoe production, the structure of which includes a base, a coating assembly, an adaptability adjustment assembly, and a metering delivery assembly. The following description is in conjunction with the appendix. Figures 1 to 4 The specific embodiments of this utility model are described in detail with reference to the component numbers marked in the accompanying drawings.

[0023] like Figure 1 As shown, the core components of the entire device are all mounted on a base. The coating assembly is located at the front end of the top of the base, the adaptive adjustment assembly is arranged on the top of the base and close to the side of the coating assembly, and the quantitative delivery assembly is located inside the base and connected to the rear end of the coating assembly via a pipe. The coating assembly mainly includes a coating head 1, a flexible coating sheet 2, an elastic pressure strip 3, a coating chamber 4, and a flow guide channel 5. The coating head 1 is fixed to the front end of the coating assembly by a threaded connection. The flexible coating sheet 2 is installed at the bottom of the coating head 1, and elastic pressure strips 3 are symmetrically fixed to both sides of the flexible coating sheet 2. The coating head 1 has a coating chamber 4 inside, and multiple flow guide channels 5 are evenly distributed at the bottom of the coating chamber 4. The design of the flow guide channels 5 can ensure that the flow speed of the liquid in the coating chamber 4 is consistent. The rear end of the coating head 1 is connected to the output end of the quantitative delivery assembly via a pipe, and a sealing ring is provided on the inner wall of the pipe to prevent liquid leakage. The flexible coating sheet 2 is made of a polymer material, and its surface has a microporous structure, which can evenly distribute the waterproofing agent to the surface to be treated under capillary action. The elastic pressure strip 3 is made of spring steel and is fixed to both sides of the coating head 1 by screws at both ends. During the coating process, it automatically adjusts the pressure according to the curvature of the contact surface, thereby achieving a tight fit to complex surfaces.

[0024] The adaptive adjustment assembly includes an adjusting rod 6, a sliding block 7, a guide rail 8, an adjusting motor 9, and an eccentric wheel 10. For example... Figure 3As shown, one end of the adjusting rod 6 is hinged to the top of the coating head 1, and the other end is fixed to the sliding block 7. The sliding block 7 is slidably connected to the inner wall of the guide rail 8, which is bolted to the top of the base. An eccentric wheel 10 is attached to one side of the sliding block 7. The central shaft of the eccentric wheel 10 is connected to the output shaft of the adjusting motor 9 via a coupling, and the adjusting motor 9 is bolted to the top of the base. A lubricating coating is provided on the inner wall of the guide rail 8 to reduce the frictional resistance of the sliding block 7 during movement and improve the adjustment accuracy. When the adjusting motor 9 drives the eccentric wheel 10 to rotate, the eccentricity of the eccentric wheel 10 pushes the sliding block 7 to reciprocate along the guide rail 8, thereby driving the adjusting rod 6 to move up and down, ultimately achieving the vertical position adjustment of the coating head 1. The eccentricity of the eccentric wheel 10 can be adjusted according to actual needs to change the range of motion of the coating head 1.

[0025] The metering delivery assembly includes a storage tank 11, a metering pump 12, a flow sensor 13, a delivery pipe 14, and a control module 15. For example... Figure 4 As shown, the storage tank 11 is welded and fixed inside the base, and a metering pump 12 is connected to its bottom via a flange. The output end of the metering pump 12 is connected to the rear end of the coating head 1 via a delivery pipe 14, and a flow sensor 13 is installed on the outer wall of the delivery pipe 14. The flow sensor 13 is connected to the control module 15 via a signal line, and the control module 15 is fixed to the side wall of the base with screws. The storage tank 11 is used to store the waterproofing agent, and the metering pump 12 draws the waterproofing agent from the storage tank 11 according to a set flow rate and delivers it to the coating head 1 through the delivery pipe 14. The flow sensor 13 monitors the liquid flow rate in the delivery pipe 14 in real time and transmits the data to the control module 15. The control module 15 dynamically adjusts the operating parameters of the metering pump 12 based on the data fed back by the flow sensor 13, thereby achieving precise supply of the waterproofing agent.

[0026] In actual operation, the waterproofing agent is first injected into the storage tank 11. After the metering pump 12 is started, the waterproofing agent is transported to the coating chamber 4 of the coating head 1 through the delivery pipe 14. The waterproofing agent in the coating chamber 4 is evenly distributed onto the flexible coating sheet 2 through the guide groove 5. Then, the flexible coating sheet 2 uses its microporous structure to evenly coat the waterproofing agent onto irregular surfaces such as the shoe upper or sole edge. During this process, the elastic pressure strip 3 automatically adjusts the pressure according to the curvature of the contact surface, so that the flexible coating sheet 2 can closely adhere to the complex surface, thereby achieving uniform coating. At the same time, the adaptive adjustment component drives the eccentric wheel 10 to rotate through the adjustment motor 9, which drives the sliding block 7 to move back and forth along the guide rail 8, and then adjusts the height of the coating head 1 through the adjustment rod 6 to adapt to the surface to be treated at different heights. In addition, the quantitative delivery component monitors the flow rate of the waterproofing agent in real time through the flow sensor 13 and transmits the data to the control module 15. The control module 15 dynamically adjusts the operating parameters of the metering pump 12 according to the feedback information to ensure that the supply of waterproofing agent is always kept within the set range.

[0027] This invention solves the problem of existing technologies being unable to adapt to complex curved surfaces by utilizing the flexible coating sheet 2 and the elastic pressure strip 3 in the coating assembly, enabling the device to uniformly coat irregular surfaces such as shoe uppers and sole edges. The adaptability adjustment assembly, through the linkage design of the eccentric wheel 10 and the sliding block 7, achieves automatic height adjustment of the coating head 1, further improving the applicability of the device. The quantitative delivery assembly, through the coordinated operation of the metering pump 12 and the flow sensor 13, avoids waste of waterproofing agent or uneven coating, significantly improving resource utilization. To better enable those skilled in the art to fully understand and implement this invention, the specific implementation principle of this invention is further explained below with reference to a specific application scenario.

[0028] In actual operation, the waterproofing agent is first injected into the storage tank 11. The initial operating parameters of the metering pump 12 are set by the control module 15, and the metering pump 12 is started. At this time, the waterproofing agent is drawn from the storage tank 11 and delivered through the delivery pipe 14 to the coating chamber 4 of the coating head 1. The flow sensor 13 installed on the outer wall of the delivery pipe 14 monitors the liquid flow rate in real time and transmits the data to the control module 15. The control module 15 dynamically adjusts the operating parameters of the metering pump 12 based on the data fed back by the flow sensor 13, ensuring that the supply of waterproofing agent is always kept within the preset range. This process, through the coordinated action of the flow sensor 13 and the metering pump 12, achieves precise delivery of the waterproofing agent, avoiding uneven application caused by excessive or insufficient application.

[0029] Once the waterproofing agent enters the coating chamber 4, the uniformly distributed guide channels 5 within it play a crucial role. The design of the guide channels 5 optimizes the liquid flow path, allowing the waterproofing agent to flow to the flexible coating sheet 2 at a consistent speed. The flexible coating sheet 2 is made of a polymer material with a microporous surface, which, under capillary action, evenly adsorbs and distributes the waterproofing agent onto the surface to be treated. During this process, the elastic pressure strip 3 automatically adjusts the applied pressure according to changes in the curvature of the contact surface, ensuring that the flexible coating sheet 2 can closely conform to complex curved surfaces. For example, when the coating head 1 contacts the edge of the shoe sole, the spring steel material of the elastic pressure strip 3 allows it to bend flexibly, providing appropriate support for the flexible coating sheet 2, thereby ensuring that the waterproofing agent is evenly covered on irregular surfaces.

[0030] Meanwhile, the adaptive adjustment mechanism comes into play. The adjusting motor 9 drives the eccentric wheel 10 to rotate, and the eccentricity of the eccentric wheel 10 pushes the sliding block 7 to reciprocate along the guide rail 8. The movement of the sliding block 7 is transmitted to the coating head 1 via the adjusting rod 6, causing the coating head 1 to adjust its position in the vertical direction. For example, when coating a higher part of the shoe upper, the rotation of the eccentric wheel 10 causes the sliding block 7 to move upward, thereby raising the height of the coating head 1; while when processing a lower area, the sliding block 7 moves downward, lowering the position of the coating head 1. This height adjustment mechanism allows the device to adapt to surfaces of different heights, significantly improving the applicability of the equipment.

[0031] Furthermore, the lubricating coating in the adaptive adjustment assembly reduces the frictional resistance of the sliding block 7 as it moves within the guide rail 8, improving adjustment accuracy. The eccentricity of the eccentric wheel 10 can be adjusted according to actual needs to expand or shrink the range of motion of the coating head 1, meeting the requirements of different production scenarios. For example, for fine areas such as the edge of the shoe sole, the eccentricity can be reduced for finer adjustment; while for larger areas of the shoe upper, the eccentricity can be increased to improve work efficiency.

[0032] After completing the above steps, the entire device enters a stable operating state. The coating head 1, through the cooperation of the flexible coating sheet 2 and the elastic pressure strip 3, can achieve uniform coating on irregular surfaces such as shoe uppers and sole edges. Simultaneously, the metering delivery component continuously monitors and adjusts the supply of waterproofing agent to ensure consistent dosage for each application. For example, when the flow sensor 13 detects that the flow rate in the delivery pipe 14 is lower than the set value, the control module 15 immediately instructs the metering pump 12 to increase its output power to compensate for the insufficient flow; conversely, if the flow rate exceeds the set value, the control module 15 reduces the workload of the metering pump 12 to avoid waste.

[0033] Through the coordinated operation of the above steps, this invention solves the problem of existing technologies being unable to adapt to complex curved surfaces, and achieves effective processing of various materials and shapes for casual shoes. The automatic height adjustment function of the adaptive adjustment component further enhances the flexibility of the device, while the quantitative conveying component significantly improves resource utilization and reduces production costs. These improvements not only meet the special requirements of casual shoe production, but also possess high practical value and promising prospects for promotion.
