Description

Technical Field

[0001] This invention relates to the field of shoe manufacturing technology, and in particular to a reverse-stitched synchronous reinforcement belt device and its usage method. Background Technology

[0002] In existing shoe manufacturing processes, two steps—reverse stitching and reinforcement—are required at the joints to ensure their strength. The reinforcement process includes attaching and cutting reinforcing tape. Typically, these three steps require different workers, reducing production efficiency and increasing working time. Therefore, a device that integrates reverse stitching, reinforcing tape attachment, and cutting is needed. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a reverse stitching synchronous reinforcement tape device, which realizes the integrated operation of reverse stitching of shoe upper, reinforcement tape bonding and cutting, thereby improving production efficiency and reducing time costs.

[0004] This invention is accomplished using the following technical solution: a reverse-stitching synchronous reinforcement tape device, comprising a base, a sewing mechanism, a reinforcement tape feeding mechanism, a reinforcement tape bonding mechanism, a conveying mechanism, and a cutting mechanism. The conveying mechanism includes a front conveyor belt and a rear conveyor belt, which are respectively mounted on the base. The sewing mechanism is positioned between the front and rear conveyor belts. The reinforcement tape bonding mechanism and the cutting mechanism are sequentially mounted on the housing and located above the rear conveyor belt. The reinforcement tape feeding mechanism is positioned above the housing. The housing is mounted on the base via multiple support frames. Clamping and conveying mechanisms are symmetrically arranged on both sides of the housing. The reinforcement tape is installed in the reinforcement tape feeding mechanism and sequentially passes through two transmission wheels to the reinforcement tape bonding mechanism. The shoe upper is conveyed to the sewing mechanism via the front conveyor belt for reverse stitching. The stitched shoe upper is then conveyed to the rear conveyor belt, which drives the stitched shoe upper to the reinforcement tape bonding mechanism. The rear conveyor belt, in cooperation with the reinforcement tape bonding mechanism, bonds the reinforcement tape to the stitched area of ​​the shoe upper and then conveys it to the cutting mechanism for cutting.

[0005] The reinforcing tape feeding mechanism includes a belt reel and an adhesive applicator. The adhesive applicator includes an adhesive applicator box and an adhesive applicator roller, an adhesive box, and a scraper placed inside the adhesive applicator box. The adhesive box has a first adhesive applicator roller and a second adhesive applicator roller that cooperate with each other. The first adhesive applicator roller is placed inside the adhesive box, and the second adhesive applicator roller passes through the side wall of the adhesive box. The second adhesive applicator roller is located between and abuts against the first adhesive applicator roller and the adhesive applicator roller. One end of the scraper is fixed to the inner wall of the adhesive box, and the other end of the scraper extends to the adhesive applicator roller. The adhesive box has symmetrical inlet and outlet ports on both sides. A drive roller is provided at the inlet port. The reinforcing tape roll is installed on the belt reel. The reinforcing tape is wound around the drive roller and passes through the inlet port and outlet port in sequence. The bottom of the adhesive applicator roller abuts against the reinforcing tape, and the adhesive is applied to the reinforcing tape by the adhesive applicator roller.

[0006] The two drive wheels are located at the end of the housing near the needle mechanism. The two drive wheels are symmetrically arranged at the upper and lower ends of the housing. The adhesive-coated reinforcing strip passes through the two drive wheels in sequence to the space between the reinforcing strip bonding mechanism and the rear conveyor belt. The reinforcing strip bonding mechanism presses the reinforcing strip towards the rear conveyor belt. The transmission frequencies of the front conveyor belt, the rear conveyor belt and the clamping conveyor mechanism are the same.

[0007] The reinforcing strip bonding mechanism consists of at least two pressing roller devices. Each pressing roller device includes a roller support, a first telescopic rod, and a pressing roller. The first telescopic rod is installed between the roller support and the pressing roller, and a return spring is sleeved on the first telescopic rod.

[0008] The clamping and conveying mechanism consists of a conveyor belt support and two sets of conveyor belts. The two sets of conveyor belts are tractably mounted on the conveyor belt support, and a channel for the shoe fabric to pass through is formed between the two sets of conveyor belts.

[0009] Furthermore, an infrared sensor is provided between the cutting mechanism and the reinforcing strip bonding mechanism. After the shoe upper is bonded by the reinforcing strip bonding mechanism, the infrared sensor monitors the position of the shoe upper and transmits the signal to the cutting mechanism. The cutting mechanism then starts working and cuts the reinforcing strip downwards.

[0010] Furthermore, the cutting mechanism includes a base, a cylinder, and a cutting blade assembly. The cylinder is mounted on the base, which is located on the housing. The cutting blade assembly is located at the bottom of the cylinder. The cylinder is connected to a cylinder control valve via an air pipe. The cylinder control valve is connected to an external air source and has a signal receiving device.

[0011] Furthermore, the needle-making mechanism includes a machine base and a worktable. The machine base is equipped with a needle, and the upper surface of the worktable is flush with the upper surfaces of the front and rear conveyor belts and located below the needle.

[0012] In this invention, the sewing mechanism, reinforcing tape bonding mechanism, and cutting mechanism work sequentially in cooperation with the conveying mechanism to realize an integrated production line system for reverse sewing, reinforcing tape bonding, and reinforcing tape cutting of shoe uppers, thereby improving production efficiency and saving production time.

[0022] The technical solutions in the embodiments of this patent will be clearly and completely described below with reference to the present invention. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0023] Reference Figures 1-7 As shown, the present invention provides a first embodiment of a reverse-stitched synchronous reinforcing tape device, including a base 1, a needle-stitching mechanism 2, a reinforcing tape feeding mechanism 3, a reinforcing tape bonding mechanism 4, a conveying mechanism 5, and a cutting mechanism 6. The conveying mechanism includes a front conveyor belt 51 and a rear conveyor belt 52, which are respectively mounted on the base 1. The needle-stitching mechanism 2 is positioned between the front conveyor belt 51 and the rear conveyor belt 52. The reinforcing tape bonding mechanism 4 and the cutting mechanism 6 are sequentially mounted on a housing 7 and located above the rear conveyor belt 52. The reinforcing tape feeding mechanism 3 is positioned above the housing 7, wherein the housing 7 is mounted on the base 1 via multiple support frames 71. The reinforcing tape 11 is installed in the reinforcing tape feeding mechanism 3 and sequentially passes through two drive wheels 9 to the reinforcing tape bonding mechanism 4. The workflow is as follows: the shoe upper is conveyed by the front conveyor belt 51 to the sewing mechanism 2 for reverse sewing. The sewn shoe upper is then transferred to the rear conveyor belt 52, which drives it towards the reinforcing tape bonding mechanism 4. The rear conveyor belt 52, in conjunction with the reinforcing tape bonding mechanism 4, bonds the reinforcing tape to the seam of the shoe upper and then transmits it to the cutting mechanism 6 for shearing, completing the reverse sewing and reinforcing tape bonding process of the shoe upper. This device is preferably used for reverse sewing and reinforcing tape bonding at the heel of two pieces of shoe upper.

[0024] The sewing mechanism 2 includes a machine base 21 and a worktable 22. The worktable 22 is disposed between the front conveyor belt 51 and the rear conveyor belt 52, and the upper surface of the worktable 22 is flush with the upper surfaces of the front conveyor belt 51 and the rear conveyor belt 52. The machine base is equipped with a sewing needle 23, and the worktable 22 is located below the sewing needle 23.

[0025] The reinforcing tape feeding mechanism 3 includes a winding pulley 31 and an adhesive applicator 32. The winding pulley 31 and the adhesive applicator 32 are mounted on a feeding frame 33. The reinforcing tape roll is mounted on the winding pulley, and the reinforcing tape 11 can be continuously pulled out with the cooperation of the winding pulley 31. The adhesive applicator 32 includes an adhesive applicator box 321 and an adhesive applicator roller 322, an adhesive applicator box 323, and a scraper 324 placed inside the adhesive applicator box. The adhesive applicator box has symmetrically arranged inlet ports 325 and outlet ports 326 on both sides, and a drive roller 327 is provided at the inlet port 325. The glue application box 323 is equipped with a first glue application roller 328 and a second glue application roller 329 that cooperate with each other. The first glue application roller 328 is placed inside the glue application box and is in contact with the glue inside the box. The second glue application roller 329 is inserted through the side wall of the glue application box (i.e., part of the glue application roller is located in the inner cavity of the glue application box, and the other part of the glue application roller is located outside the glue application box). The second glue application roller 329 is located between and abuts against the first glue application roller 328 and the glue spreading roller 322. One end of the scraper 324 is fixed to the inner wall of the glue application box, and the other end of the scraper extends to the glue spreading roller 322. The first glue application roller 328 transfers the glue to the second glue application roller 329, and then the second glue application roller 329 transfers it to the glue spreading roller 322. The scraper 324 smoothly spreads the glue evenly on the surface of the glue spreading roller. As the reinforcing strip passes around the drive roller 327 and sequentially through the feed inlet 325 into the glue application box 321, the bottom of the glue application roller 322 abuts against the reinforcing strip 11, and the glue is evenly applied to the reinforcing strip 11 by the glue application roller 322. The glued reinforcing strip 11 then exits through the discharge port 326. Two drive wheels 9 are provided at the end of the housing 7 near the needle-making mechanism. The two drive wheels 9 are symmetrically arranged at the upper and lower ends of the housing end, respectively. After being glued, the reinforcing strip sequentially passes around the two drive wheels 9 to the space between the reinforcing strip bonding mechanism 4 and the rear conveyor belt 52. The reinforcing strip bonding mechanism 4 presses the reinforcing strip 11 tightly towards the rear conveyor belt.

[0026] The reinforcing strip bonding mechanism 4 consists of at least two pressing roller devices. Each pressing roller device includes a roller support 41, a first telescopic rod 42, and a pressing roller 43. The first telescopic rod 42 is installed between the roller support 41 and the pressing roller 43. A return spring 44 is sleeved on the first telescopic rod 42. With the cooperation of the return spring 44, the pressing roller 43 always presses in the direction of the rear conveyor belt, which facilitates bonding the reinforcing strip to the shoe upper.

[0027] An infrared sensor 10 is installed between the cutting mechanism 6 and the reinforcing strip bonding mechanism 4. After the shoe upper is bonded by the reinforcing strip bonding mechanism 4, the infrared sensor 10 monitors the position of the shoe upper and transmits a signal to the cutting mechanism 6. The cutting mechanism then starts working and cuts the reinforcing strip 11 downwards. Specifically, the cutting mechanism 6 includes a base 61, a cylinder 62, and a cutting blade assembly 63. The base 61 is mounted on the housing 7, the cylinder 62 is mounted on the base 61, and the cutting blade assembly 63 is located at the bottom of the cylinder 62. The cylinder 62 is connected to a cylinder control valve via an air pipe. The cylinder control valve is connected to an external air source and has a signal receiving device (the connection method between the cylinder and the cylinder control valve and the signal receiving device are existing technologies and are not shown in the figures). When the infrared sensor 10 detects the shoe upper, it transmits a signal to the signal receiving device. The cylinder control valve then drives the cutting blade assembly 63 to fall according to a set time interval, thereby cutting the reinforcing strip 11. The cutting mechanism 63 includes a cutter holder 631 and a cutter 632 mounted on the holder. The cutter holder 631 is installed at the bottom of the cylinder 62. There is one cutter 632. The interval between the start-up of the cylinder control valve is set according to the required length of the reinforcing strip. An infrared sensor detects the shoe upper leaving the reinforcing strip bonding mechanism and transmits a signal to the cylinder control valve, driving the cylinder to start working. The cutter falls twice to complete one cutting process. The interval between the two falls is set according to the required length of the reinforcing strip to be cut.

[0028] The housing 7 is symmetrically equipped with clamping and conveying mechanisms 8 on both sides. The transmission frequencies of the front conveyor belt 51, the rear conveyor belt 52, and the clamping and conveying mechanisms 8 are the same. Each clamping and conveying mechanism 8 consists of a conveyor belt support 81 and two sets of conveyor belts. The two sets of conveyor belts are mounted on the conveyor belt support 81, and a conveying channel for the shoe fabric to pass through is formed between the two sets of conveyor belts 82. The conveyor belt includes a drive track 82, a drive wheel 83, a driven wheel 84, and multiple sets of drive wheel assemblies 85. The drive wheel 83 and the driven wheel 84 are respectively located at both ends of the inner side of the drive track 82. The drive wheel 83 is connected to the support motor 86 through a drive shaft 831, and the driven wheel 84 is mounted on the conveyor belt support 81 through a connecting shaft 841. Multiple sets of drive wheel assemblies 85 are evenly arranged between the drive wheel 83 and the driven wheel 84. The transmission wheel assembly 85 includes a rotating wheel 851 and a pressure wheel 852. The rotating wheel is connected to the conveyor belt support 81 via a second connecting shaft 853 and can rotate along the second connecting shaft 853. The pressure wheel 852 is connected to the second connecting shaft via a third connecting shaft 855 through a second telescopic rod 856. A return spring 857 is sleeved on the second telescopic rod. Preferably, there are two second telescopic rods 856, distributed at the upper and lower ends of the third connecting shaft. The pressure wheel 852 can rotate along the third connecting shaft 855. The driving wheel 83, driven wheel 84, pressure wheel 852, and rotating wheel 851 all abut against the inner side of the transmission track 82. The pressure wheels 852 in the two sets of conveyor belts press against the direction of the transmission channel, so that the shoe upper is clamped in the transmission channel and sequentially transmitted in the direction of the cutting mechanism. The clamping and conveying mechanism 8 holds both ends of the shoe upper to prevent displacement, ensuring that the stitching of the shoe upper is sequentially located below the stitching mechanism, the reinforcing tape bonding mechanism, and the cutting mechanism, thus ensuring that the stitching, reinforcing tape bonding, and reinforcing tape cutting processes are accurately aligned and carried out smoothly.

[0029] The steps for using the aforementioned reverse suture synchronous reinforcement belt device are as follows:

[0030] 1) Install the reinforcing tape 11. Install the reinforcing tape roll on the reel. One end of the reinforcing tape is pulled out from the reinforcing tape roll and passes through the drive roller 327 into the gluing device 32. The glue application roller 322 in the gluing device evenly applies glue to the reinforcing tape and passes out of the gluing device. The glued reinforcing tape 11 passes through the two drive rollers 9 in sequence and is transported between the reinforcing tape bonding mechanism 4 and the rear conveyor belt 52.

[0031] 2) Reverse stitching of shoe upper. Take two pieces of fabric to be stitched, and clamp the ends of the two pieces away from the stitching area onto the two clamping conveyor mechanisms 8 on both sides. Position the inner surface of the shoe upper with the stitching facing upwards to facilitate reverse stitching. The worker arranges the two pieces of fabric at the stitching area on the upper end of the front conveyor belt and manually positions the stitching point. The fabric is then conveyed to the sewing mechanism 2 via the front conveyor belt, where the sewing mechanism 2 stitches the seam of the shoe upper. Once the sewing mechanism 2 completes the reverse stitching of the shoe upper, the worker repeats step 2 to reverse stitch the next set of shoe uppers.

[0032] 3) Reinforcing tape bonding. The sewn shoe upper is moved towards the rear conveyor belt 52 with the cooperation of the clamping and conveying mechanisms 8 on both sides. The rear conveyor belt 52 and the clamping and conveying mechanisms work together to transfer the sewn shoe upper to the space between the reinforcing tape bonding mechanism 4 and the rear conveyor belt 52. The reinforcing tape 11 with glue applied is located below the pressing roller 43. The sewn part of the shoe upper is transferred to the area below the reinforcing tape via the rear conveyor belt and pressed onto the sewn part of the shoe upper by the pressing roller 43, thus completing the bonding of the reinforcing tape.

[0033] 4) Cutting the reinforcing tape. After the reinforcing tape is bonded to the shoe upper, it passes through the rear conveyor belt 52 and the clamping conveyor mechanism 8 and leaves the pressing roller device. When the infrared sensor 10 detects the position of the shoe upper, it sends a signal to the cutting mechanism. The cutting mechanism receives the signal and starts working, controlling the time and speed of the cutter's descent to complete the cutting of the reinforcing tape.

[0034] The aforementioned reverse stitching synchronous reinforcement tape device can be installed on the operating table 12 and operated by the worker. At the same time, a placement frame 13 can be placed at the rear end of the operating table. After the shoe upper reinforcement tape is cut, the clamping and conveying mechanism continues to convey it backward until the stitched shoe upper falls into the placement frame.

[0035] Reference Figure 8As shown, this invention provides a second embodiment of a reverse-stitched synchronous reinforcement belt device, which is basically the same as the first embodiment, except that: the cutter assembly 63 includes a cutter seat 631 and two cutters 632 adjustablely mounted on the cutter seat. The cutter seat 631 is mounted on the bottom of the cylinder 62, and the distance between the two cutters is adjustable on the cutter seat 631. The distance between the two cutters 632 is adjusted according to the required length of the reinforcement belt. Specifically, the bottom of the cutter seat 631 is provided with a mounting groove 633, and the two sides of the cutter seat have symmetrical connecting channels 634 that penetrate the mounting groove. An adjusting screw 635 passes through the connecting channel 634 and the mounting groove 633 in sequence. The two cutters are connected to the adjusting screw 635 with forward and reverse threads, respectively. An adjusting handwheel 636 is fixed to the end of the adjusting screw. Rotating the adjusting screw 635 drives the two cutters 632 to move in opposite directions, thereby adjusting the distance between the cutters. The placement groove has a positioning groove 637 at its top, and the cutter has a positioning block 638 at its top. The positioning block engages with the positioning groove to prevent the cutter from rotating, allowing the cutter to move along the trajectory of the positioning groove. The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
