Automatic PUR laminator for shoemaking

Abstract

The utility model discloses an automatic PUR (Polyurethane) laminator for shoemaking, which comprises a rack, a pump body is arranged on the rack, and the pump body is connected and communicated with a glue storage tank arranged on the rack; a glue rolling device is further arranged on the machine frame and located under a glue outlet pipe arranged on the pump body. The glue rolling device comprises a roller used for driving the insole to move towards the interior of the glue rolling device, a material supporting frame and a glue scraping plate. Due to the fact that the roller is located under the glue outlet pipe, when glue drips on the roller and is matched with the arranged glue scraping plate, the dripped glue can be evenly distributed on the roller, at the moment, the insole is placed on the material supporting frame, the rolling roller drives the insole to move, and the glue is evenly smeared on the insole. In addition, due to the arrangement of the material supporting frame, the insole can be prevented from being rolled into the glue rolling device, so that the insole gluing can be continuously carried out; therefore, the automatic gluing device not only realizes automatic gluing, but also can improve the gluing efficiency.

Description

Technical Field

[0001] This utility model relates to the field of shoemaking technology, specifically to an automatic PUR gluing machine for shoemaking. Background Technology

[0002] With the development of technology, reactive polyurethane hot melt adhesives (hereinafter referred to as "PUR adhesives") have emerged. These adhesives are produced by heating and melting into a fluid under conditions that inhibit chemical reactions, facilitating application. After the two substrates are bonded together, the adhesive layer solidifies, providing adhesion. Subsequently, with the help of moisture present in the air or adhering to the surfaces of the substrates, they react and extend their chains, generating a high-polymer with strong cohesion, significantly improving adhesion and heat resistance. Compared with ordinary hot melt adhesives, it possesses superior comprehensive properties such as heat resistance, cold resistance, creep resistance, and resistance to various media. Its application temperature is also lower than that of ordinary hot melt adhesives, leading to its increasing application and rapid development in modern industry.

[0003] However, the existing glue application methods are mostly manual, which is not only inefficient but also results in uneven glue application. In addition, shoe manufacturing companies are labor-intensive enterprises, and purchasing large equipment not only occupies factory space but also seriously consumes the company's funds.

[0006] As a preferred technical solution of this utility model: it also includes a frame, and a glue storage tank is provided on the frame, and a pump body is provided at the glue outlet of the glue storage tank. The pump body is connected to the glue outlet pipe, and the glue rolling device is fixedly connected to the frame by a bracket.

[0007] As a preferred technical solution of this utility model: the bracket is further provided with a first cylinder, the cylinder body of the first cylinder is fixed on the bracket, and the rod body of the first cylinder is connected to a second linkage rod through a first linkage rod, and the other end of the second linkage rod is linked with the scraper.

[0008] As a preferred technical solution of this utility model: the support frame is further provided with a support plate with an opening at one end; wherein, the support plate is used to connect the scraper, the material support frame and the roller shaft pin to the support frame; a second cylinder is also provided on the side of the support plate away from the opening end, the second cylinder passes through the support plate and is connected to a brush plate, and the bristles of the brush plate face the roller.

[0009] As a preferred technical solution of this utility model: the brush plate is slidably connected to the support plate by a provided slide plate, and the brush plate slides on the slide plate by pushing and pulling the provided pull rod.

[0010] As a preferred technical solution of this utility model: the bracket is further provided with an outer cover, the outer cover is used to cover the first cylinder on the bracket, and a shaft pin seat is fixedly connected below the outer cover, the shaft pin seat is used to support the first linkage rod and allow the first linkage rod to rotate axially inside it.

[0011] As a preferred technical solution of this utility model: a pressure roller is also slidably connected to the bracket, and the roller meshes with the driving gear on the external motor through a driven gear.

[0012] The beneficial effects of this utility model by adopting the above technical solution are as follows: 1.

For example, it can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection, an electrical connection, or a connection that can communicate with each other; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two elements or an interaction relationship between two elements. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] Please see Figure 1-3 This utility model provides an embodiment of an automatic PUR gluing machine for shoe manufacturing, including a gluing device 3 located below a glue dispensing tube 6. The gluing device 3 includes a support frame 31, and a roller 37 is provided on the support frame 31. A material support frame 39 for supporting the midsole and a scraper 310 for evenly applying the glue dripping from the glue dispensing tube 6 onto the roller 37 are provided on one side of the roller 37. Through the above technical solution, the device can evenly apply the glue onto the midsole. At the same time, the material support frame 39 can prevent the roller 37 from rolling the midsole into the inside of the gluing device 3, thus greatly reducing the downtime of the device, improving work efficiency, and preventing the glue from solidifying due to downtime.

[0020] To further integrate the PUR coating machine, a frame 5 is also included, on which a glue storage tank 1 is mounted. A pump body 7 is located at the glue outlet of the glue storage tank 1, and the pump body 7 is connected to the glue outlet pipe 6. The roller coating device 3 is fixedly connected to the frame 5 via a bracket 4. By setting the frame 5 to concentrate the glue storage tank 1 and the pump body 7 on one side of the frame 5, and installing the roller coating device 3 on the other side of the frame 5, the installation positions of the roller coating device 3, the pump body 7, and the glue storage tank 1 are further optimized, resulting in a more compact structure and significantly reducing the size of existing coating machines. Furthermore, the compact structure and concentrated components facilitate maintenance and repair, further reducing downtime due to maintenance.

[0021] To ensure a uniform thickness of the adhesive on the roller 37, a first cylinder 36 is provided on the support 4. The cylinder body of the first cylinder 36 is fixed on the support 4, and the rod body of the first cylinder 36 is connected to a second linkage rod 33 via a first linkage rod 35. The other end of the second linkage rod 33 is linked to the scraper 310. The first cylinder 36 drives the scraper 310 to move away from or towards the roller 37, thus making the thickness of the adhesive coating on the roller 37 easier to control and ensuring a uniform coating.

[0022] To facilitate the installation of the roller 37, the scraper 310, and the material support frame 39, and to ensure that all three can rotate on the support frame 31, the support frame 31 is also provided with a support plate 312 with an opening at one end; wherein, the support plate 312 is used to connect the scraper 310, the material support frame 39, and the roller 37 to the support frame 31 by a pin.

[0023] Since a second cylinder 30 is provided on the side of the support plate 312 away from the opening end, the second cylinder 30 passes through the support plate 312 and is connected to a brush plate 38, and the bristles of the brush plate 38 face the roller 37, the brush plate 38 can clean the adhesive on the roller 37, thereby facilitating the cleaning of the roller 37 and ensuring the quality of the midsole adhesive.

[0024] To further ensure the quality of the adhesive application and facilitate the cleaning of the adhesive on the roller 37, the brush plate 38 is slidably connected to the support plate 312 via a sliding plate 313. The brush plate 38 slides on the sliding plate 313 by pushing and pulling the pull rod 32. The back-and-forth pulling of the pull rod 32 and the friction between the brush bristles and the outer wall of the roller 37 further clean the adhesive.

[0025] To further optimize the external structure of the device and ensure the smooth axial rotation of the first linkage rod 35, thereby achieving smooth power output, the bracket 4 is also provided with an outer cover 8. The outer cover 8 is used to cover the first cylinder 36 on the bracket 4, and a shaft pin seat 34 is fixedly connected below the outer cover 8. The shaft pin seat 34 is used to support the first linkage rod 35 and allow the first linkage rod 35 to rotate axially inside it.

[0026] Since the roller coating device 3 applies the adhesive to the midsole, it can only ensure that the adhesive adheres to the midsole and penetrates deeper into the midsole, thus not solving the above-mentioned problems. The support 4 of the device is also slidably connected to a pressure roller 2, which is slidably connected to a slide rail on the support 4 via a slider. Therefore, the specific position of the pressure roller 2 pressing the midsole can be adjusted. At the same time, the pressure roller 2 can be adjusted up and down via a handwheel 9. Thus, the position of the pressure roller 2 can be adjusted in multiple directions, thereby ensuring full contact between the adhesive and the midsole, further improving the adhesive coating quality of the midsole and avoiding rework. This greatly improves the adhesive coating efficiency. In addition, the roller 37 meshes with the drive gear on the external motor through a driven gear 311, which ensures reliable power transmission and smooth power transmission, thus also helping to improve the adhesive coating quality.

[0027] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
