Description

Technical Field

[0001] The invention belongs to the technical field of daily necessities, and particularly relates to an integrated manufacturing device and a manufacturing method thereof, and indoor slippers manufactured thereby. Background Art

[0002] "Indoor slippers," as the name suggests, are shoes designed specifically for indoor wear. Existing indoor slippers are essentially based on the concept of "slippers." Slippers are divided into two types: reusable and disposable. Both are limited to a single style, presenting a clear shortcoming in a society and market with increasingly sophisticated aesthetic requirements.

[0003] Reusable slippers are typically manufactured using a one-shot polymer molding process. These slippers are typically sold in lower-end markets because the polymers used are not breathable and do not absorb foot sweat, leading to the widespread problem of "stinky feet." Alternatively, slippers are made by combining textile fabric with polymers through multiple production processes. These traditional processes, including gluing, sewing, and hot-melt, are difficult to guarantee the quality of the finished product. Often, different parts debond, threads break, and edges unravel before the material is even worn. Consequently, the entire pair of shoes faces premature scrapping, leading to an unnecessary increase in waste caused by product quality issues, a serious environmental issue.

[0004] Disposable hotel slippers are also manufactured using the traditional process mentioned above. However, because they are disposable, manufacturers often use less durable and long-lasting materials to produce them. As a result, many hotel slippers cannot even meet the service life of a day.

[0005] Of course, there are also more upscale disposable slippers made from blended linen or cotton toweling. However, this raises another issue: the world's arable land is insufficient to feed the world's population. Using arable land to grow crops for disposable, consumable products is a resource utilization issue worth considering. Summary of the Invention

[0006] In light of this, the primary objective of the present invention is to provide an integrated manufacturing device for indoor slippers, resolving the issues of existing manufacturing devices' inability to achieve integration and the resulting poor quality of indoor slippers. This invention extends product life. It leverages existing technology to shift production capacity to the production of diverse styles and designs of indoor slippers, which are in high demand globally. The ultrasonic welding technology involved in this invention is combined with various polymer materials suitable for this process. This invention eliminates the need for consumables such as adhesives and sewing thread, thus minimizing the cost of processing consumables without compromising product quality. Furthermore, the manufacturing process is non-toxic and odorless, generating no waste or exhaust gas pollution.

[0007] The present invention also aims to provide a manufacturing method using the above-mentioned manufacturing device;

[0008] The present invention also aims to provide indoor slippers manufactured using the above manufacturing method.

[0009] To achieve the above-mentioned purpose, the technical solution of the present invention is implemented as follows: an integrated manufacturing device for indoor slippers, comprising a sole mold, a shoe last, a positioning mold, a first material transmission and positioning component for transmitting the sole sheet, and a second material transmission and positioning component for transmitting the upper sheet, wherein the sole mold, the first material transmission and positioning component, the shoe last, the second material transmission and positioning component, and the positioning mold are arranged in sequence from bottom to top; when the first material transmission and positioning component and the second material transmission and positioning component respectively transmit the sole sheet and the upper sheet to positions corresponding to the sole mold and the shoe last, the sole mold, the shoe last, and the positioning mold are interlocked with each other, and the upper sheet, the sole sheet, and the position where the two are combined are respectively subjected to one-piece forming and welding processing using cold pressing technology and ultrasonic welding technology.

[0010] Preferably, the sole mold is provided with a first groove corresponding to the shape of the bottom of the shoe last, and when the shoe last is placed in the first groove, a gap is formed between the first groove and the shoe last; the positioning mold is provided with a second groove corresponding to the shape of the shoe last, and when the shoe last is placed in the second groove, a gap is formed between the second groove and the shoe last.

[0011] Preferably, a first ultrasonic welding head is provided in the first groove on the sole mold; an ultrasonic cutting welding head is provided extending downward from the edge of the second groove on the positioning mold, and a second ultrasonic welding head is provided in the second groove.

[0012] The second technical solution of the present invention is achieved as follows: a method for making indoor slippers using the above-mentioned integrated manufacturing device, the method being achieved by the following steps:

[0013] S1, placing the sole sheet on top of the sole mold;

[0014] S2, placing a shoe last on top of the sole sheet, and pressing the shoe last until the sole sheet fits the sole mold;

[0015] S3, placing a shoe upper sheet on the shoe last, and pressing a positioning mold on the shoe upper sheet to fit the shoe upper sheet to the shoe last;

[0016] S4, using cold pressing technology to process the sole material and the upper material respectively, and using ultrasonic welding technology to weld the position where the upper sheet material and the sole sheet material are combined to obtain indoor slippers.

[0017] Preferably, in S1, the sole sheet is made of at least one sheet selected from meltblown non-woven fabric, spunbond fabric, PVC foam, and honeycomb 3D mesh.

[0018] Preferably, the sole sheet is one layer or multiple layers.

[0019] Preferably, in S3, the upper sheet is made of at least one sheet selected from meltblown non-woven fabric, spunbond fabric, PVC foam, and honeycomb 3D mesh.

[0020] Preferably, the upper sheet is one layer or multiple layers.

[0021] Preferably, the at least two layers of upper sheets are welded together.

[0022] The third technical solution of the present invention is achieved as follows: a pair of indoor slippers is prepared according to the above-mentioned manufacturing method.

[0036] The first material transport and positioning assembly 6 and the second material transport and positioning assembly 7 described in the following embodiment 1 are both existing technologies and therefore do not need to be introduced in detail in this document.

[0037] Example 1

[0038] An integrated manufacturing device provided by embodiment 1 of the present invention is as follows: Figure 1-8As shown, it includes a sole mold 1, a shoe last 3, a positioning mold 5, a first material transmission and positioning component 6 for transmitting the sole sheet 2, and a second material transmission and positioning component 7 for transmitting the upper sheet 4. The sole mold 1, the first material transmission and positioning component 6, the shoe last 3, the second material transmission and positioning component 7 and the positioning mold 5 are arranged in sequence from bottom to top; when the first material transmission and positioning component 6 and the second material transmission and positioning component 7 respectively transmit the sole sheet 2 and the upper sheet 4 to the positions corresponding to the sole mold 1 and the shoe last 3, the sole mold 1, the shoe last 3 and the positioning mold 5 are interlocked with each other, and the cold pressing technology and the ultrasonic welding technology are used to perform one-piece welding treatment on the upper sheet 4, the sole sheet 2 and the position where the two are combined; in the specific implementation process, the cold pressing technology is mainly used to weld the upper sheet 4 and the sole sheet 2, and the ultrasonic welding technology is mainly used to perform one-piece welding treatment on the position where the upper sheet 4 and the sole sheet 2 are combined.

[0039] By adopting the above scheme, the manufacturing device of the present invention not only achieves the goal of integrated shoemaking, but also reduces production costs and increases production efficiency. It also improves the quality of indoor slippers, extends their service life, and reduces waste caused by premature scrapping. Furthermore, the production process of the present device requires no processing consumables, generating no waste, exhaust gas, or harmful particles from processing consumables, thus reducing the environmental impact of the production process. Furthermore, the integrated manufacturing device can flexibly adapt to high-speed mass production of a variety of cost-effective and fashionable indoor slippers, further meeting the trend of consumers' increasing aesthetic demands in a progressive society. More importantly, the present invention utilizes polymers that are amenable to ultrasonic welding and does not contain natural fibers that require cultivation, thus avoiding the waste of scarce and precious arable land.

When the shoe last 3 is accommodated in the second groove 51, a gap is formed between the second groove 51 and the shoe last 3.

[0041] In this way, when the shoe last 3 is accommodated in the first groove 11, a gap is formed between the first groove 11 and the shoe last 3 to accommodate a sole sheet 2 of a certain thickness. When the shoe last 3 is accommodated in the second groove 51, a gap is formed between the second groove 51 and the shoe last 3 to accommodate an upper sheet 4 of a certain thickness, allowing the upper sheet 4 to be sandwiched therebetween for processing, thereby laying the foundation for producing high-quality indoor slippers.

[0042] Further, if Figure 1 and Figure 2 As shown, a first ultrasonic welding head 12 is provided in the first groove 11 on the sole mold 1; an ultrasonic cutting welding head 52 is provided downwardly extending from the edge of the second groove 51 on the positioning mold 5, and a second ultrasonic welding head 53 is provided in the second groove 51.

[0043] In this way, by respectively arranging the first ultrasonic welding head 12 and the second ultrasonic welding head 53 in the first groove 11 and the second groove 51, and arranging the ultrasonic cutting welding head 52 at the edge of the second groove 51, during the shoemaking process, the welding technology at the junction of the upper sheet 4 and the sole sheet 2 and the welding technology of the upper area can be carried out simultaneously, thereby laying a solid foundation for realizing the one-piece molding process.

[0044] The operating principle of the integrated production device provided in Example 1 is as follows:

[0045] When indoor slippers need to be made, the making device is started.
