[0002] With the continuous advancement of industrialization in my country, the footwear industry has also entered a period of rapid growth. However, it remains a labor-intensive industry. This rapid development has also led to a shortage of workers and rising labor costs. In the shoemaking process, gluing is largely a manual process. This is inefficient, requires a high level of technical expertise, and comes with high labor costs. Furthermore, the treatment agents and oil-based glues are volatile chemicals, which can cause long-term damage to the human body. Furthermore, traditional gluing methods are no longer practical on automated production lines, hindering productivity. Summary of the Invention

[0003] The present invention aims to solve at least one of the above problems and provides a shoe upper gluing device for an automated footwear production line.

[0004] The technical solution adopted by the present invention is as follows:

[0005] The present application provides a shoe upper gluing device for an automated footwear production line, comprising a rotating main body mechanism, a floating mechanism, a glue discharging mechanism, and a brush head mechanism;

[0006] The rotating main body mechanism includes a base, a brush head shaft assembly arranged hollow on the base, and a rotating element driving the brush head shaft assembly to rotate;

[0007] The floating mechanism includes a floating base plate and a first telescopic element fixed on the floating base plate, wherein the first telescopic element is connected to the rotating main body mechanism and is used to drive the rotating main body mechanism to perform telescopic movement;

[0008] A pressure regulating element is connected to the first telescopic element, and the pressure regulating element is used to adjust the telescopic pressure of the first telescopic element;

[0009] The glue discharging mechanism includes a glue shaft base plate, a glue discharging shaft with a glue outlet, an ejector pin and a second telescopic element;

[0010] One end of the ejector pin is connected to the second telescopic element, and the other end is placed inside the glue discharge shaft. As the second telescopic element expands and contracts, it cooperates with the glue discharge port of the glue discharge shaft to form a seal or a glue discharge channel. The glue discharge shaft is installed on the glue shaft base plate, and the glue shaft base plate is fixed to the base of the rotating main body mechanism, so that the glue discharge shaft is built into the brush head shaft assembly;

[0011] The brush head mechanism includes a glue discharging shaft head, a brush, a spacer sleeve and an outer cover;

[0012] The outer cover is placed on the spacer sleeve, the brush is clamped between the outer cover and the spacer sleeve, and the glue-discharging shaft head is placed on the spacer sleeve and extends to a position above the bottom edge of the brush;

[0013] The glue discharging shaft head is a columnar structure;

[0014] The brush head mechanism is mounted on the brush head shaft assembly through the outer cover, and the glue discharging shaft head is communicated with the glue discharging shaft.

[0015] The rotating main body mechanism provides suitable rotation speed and torque for gluing, the floating mechanism provides stable flexible floating force for the brush head mechanism through a precise pressure regulating element, and the glue discharge component forms a switch valve port for controlling glue discharge near the end of the brush head mechanism, which is convenient for accurately controlling the glue discharge amount. The brush head mechanism provides better glue brushing quality through the glue discharge shaft head of the columnar structure and the brush. The shoe upper gluing device of the present invention is applied to an automated production line, and can replace manual labor with machines to complete the upper brushing work of various types of shoes, thereby protecting the health of the operating workers and reducing labor costs.

[0016] Furthermore, the spacer is a Teflon spacer, which makes the spacer more wear-resistant while being less sticky, and the Teflon spacer has a certain anti-loosening and pre-tightening effect on the brush.

[0017] Furthermore, the glue discharging shaft head includes a connecting portion and a glue coating portion, the glue discharging shaft head is sleeved on the spacer through the connecting portion, the connecting portion is hollow, and a glue guide table and a glue coating port are formed at the connection between the connecting portion and the glue coating portion, the glue coating port is communicated with the hollow connecting portion, and when the glue flows out of the glue coating port through the hollow connecting portion, the glue guide table is used to guide the glue to the brush located on the outer peripheral side of the glue discharging shaft head;

[0018] The glue coating portion is in a columnar structure.

[0019] In existing structures, the glue-dispensing shaft head of the brush head mechanism, where it cooperates with the brush to apply glue, is spherical in structure. When applying glue, the top of the spherical structure contacts the workpiece to be coated, and the glue-applying point is located at the top of the spherical structure, making the glue-applying position difficult to control and adjust. In the present invention, the glue-dispensing shaft head of the columnar structure cooperates with the brush to apply glue, and the glue-applying point is located at the edge line of the glue-dispensing shaft head of the columnar structure. Compared with the glue-dispensing shaft head of the spherical structure, by controlling the glue-applying direction of the brush head mechanism, it is possible to apply glue to a narrower or wider adhesive strip.

[0020] During actual use, the connection portion of the glue discharging shaft head is connected to the sealing valve port of the glue discharging mechanism.

[0021] Further, the brush comprises a brush ring and a plurality of bristles, the bristles being fastened on the brush ring; the material of the brush is PBT;

[0022] The distance between the lower bottom surface of the glue applying part and the lower bottom surface of the bristles is 2-3 mm;

[0023] The distance between the lower bottom surface of the glue applying part and the end surface of the outer cover near the glue applying part is 4-6 mm.

[0024] The PBT material brush is more tenacious, and the PBT material brush is suitable for coating of water-based glue, oil-based glue and treating agent. Compared with the pig bristle brush used in the existing equipment, the PBT material brush has more accurate and neater glue edge line.

[0025] If the length of the brush beyond the glue applying part of the glue outlet shaft is too long, it is not conducive to the width control of the glue tape, and if the length is too short, it is not conducive to uniform glue brushing.

[0026] Further, the glue outlet mechanism further comprises a glue inlet pipeline, a thimble connecting shaft, an elastic element, a tee joint and a sealing plug, the glue inlet pipeline is used for conveying glue into the glue outlet shaft;

[0027] The tee joint has a first interface, a second interface and a third interface;

[0028] The first interface of the tee joint is in communication with the glue outlet shaft, the second interface is in communication with the glue inlet pipeline, and the third interface is connected with the sealing plug;

[0029] The second stretching and contracting element is a second air cylinder, and the second stretching and contracting rod is arranged on the second air cylinder;

[0030] The sealing plug is connected with the second stretching and contracting element above;

[0031] The thimble is connected with the second stretching and contracting rod of the second stretching and contracting element through the thimble connecting shaft;

[0032] The elastic element is sleeved on the second stretching and contracting rod of the second stretching and contracting element and is arranged between the sealing plug and the second stretching and contracting element.

[0033] Further, the thimble is sleeved with a thimble sealing head at one end matched with the glue outlet, and the glue outlet shaft is sleeved with a sealing valve port at one end away from the second stretching and contracting element, the thimble sealing head and the sealing valve port form sealing or the glue outlet channel when the thimble is stretched or contracted with the second stretching and contracting rod.

[0034] The glue outlet mechanism adopts thimble type sealing, and the glue outlet mechanism is controlled to open and close glue by the air cylinder and the elastic element, so that the glue amount can be more accurately controlled, and glue overflow, glue blockage and glue waste can be prevented.

[0035] Furthermore, the gluing device further includes a quick-insertion mechanism, which includes a first flange, a second flange, a wire support disc, and a wire fastener provided on the wire support disc;

[0036] The wire supporting plate is arranged between the first flange and the second flange, and the first flange is fixed to the second flange by fasteners;

[0037] The quick-insertion mechanism is fixed to the floating mechanism via the first flange.

[0038] The quick-insertion mechanism can be used to quickly replace tooling, making equipment maintenance easier.

[0039] During actual use, the gluing device is connected to the robot through a quick-insertion mechanism, and the robot automatically drives the gluing device to perform gluing operations on the periphery of the workpiece to be glued.

[0040] Furthermore, the quick plug mechanism also includes a motor plug-in female terminal, a motor plug-in male terminal and a pneumatic connector;

[0041] The pneumatic joint is mounted on the end of the first flange through a pneumatic joint fixing plate;

[0042] The motor plug-in male terminal is arranged on the first flange, and the motor plug-in female terminal is fixed on the second flange.

[0043] Furthermore, the rotating main body mechanism further includes a first connecting assembly, the first connecting assembly including an adjusting support plate and a guide rail fixing plate, one end of the guide rail fixing plate is fixed to the base, and the other end is connected to the adjusting support plate;

[0044] The guide rail fixing plate is connected to a guide rail and a slider arranged on the guide rail, and the slider is fixed to the floating base plate of the floating mechanism;

[0045] The floating mechanism further comprises a stabilizing member, which is clamped on the slide rail, with one end fixed to the slider and the other end fixed to the floating base plate. The stabilizing member is used to maintain the straightness of the slider running on the slide rail.

[0046] Furthermore, the pressure regulating element is a precision pressure reducing valve.

[0047] Furthermore, the floating mechanism further comprises a cylinder top block, a floating joint, a floating air intake joint and a dustproof muffler, wherein the floating air intake joint is arranged on the first telescopic element;

[0048] The first telescopic element is a first cylinder, and the first telescopic rod is provided on the first cylinder;

[0049] One end of the floating joint is connected to the first telescopic rod, and the other end is connected to the cylinder top block; at the same time, the cylinder top block is fixed to the base of the rotating main body mechanism;

[0050] The dustproof muffler is arranged on the first telescopic element and is used to protect the first telescopic element from being damaged by dust.

[0051] The first telescopic element is a thin free-mounted cylinder. The floating mechanism uses a precision pressure reducing valve to adjust the air intake pressure of the thin free-mounted cylinder. Guided by the micro-guide rails on both sides, it floats vertically to resist the downward pressure when gluing the shoe upper, ensuring that the bristles fit the shoe upper and achieving more precise and flexible gluing.

[0052] Furthermore, the rotating element is a brushless motor, and the output end of the rotating element is sleeved with a driving gear.

[0053] The brush head shaft assembly includes a driven shaft, a bearing, a bearing gland and a brush head shaft; the driven shaft is a hollow shaft;

[0054] The bearing sleeve is arranged on the driven shaft and is arranged on the base through a bearing cover. The brush head shaft sleeve is arranged on the driven shaft and is arranged below the bearing cover. A driven gear meshing with the driving gear is fixed on the outer periphery of the brush head shaft.

[0055] The driving gear is a steel gear and the driven gear is a resin gear. The rotating main body mechanism drives the steel gear to drive the resin gear through a DC brushless motor, thereby realizing the silent rotation of the driven shaft coated with glue.

[0056] The beneficial effects of the present invention are:

[0057] (1) The rotating main body mechanism provides a suitable rotation speed and torque for gluing, and the floating mechanism provides a stable flexible floating force for the brush head mechanism through a precise pressure regulating element.

[0058] (2) The glue-discharging shaft head of the columnar structure cooperates with the brush to apply glue. The point of applying glue is located on the edge line of the glue-discharging shaft head of the columnar structure. Compared with the glue-discharging shaft head of the spherical structure, by controlling the brushing direction of the brush head mechanism, the glue-discharging of a narrower or wider glue-coating belt can be achieved.

[0059] (3) The glue discharging mechanism adopts a pin-type seal, and the glue discharging mechanism is controlled by a cylinder and an elastic element to switch the glue on and off, which can more accurately control the glue discharging amount and prevent glue overflow, glue blockage and glue waste.

[0060] (4) The PBT brush has stronger toughness. The new PBT brush is suitable for the coating of water-based glue, oil-based glue, and treatment agent. Compared with the existing equipment using pig bristle brushes, the new PBT brush can produce more precise and neat glue edges. BRIEF DESCRIPTION OF THE DRAWINGS

The shoe upper gluing device of the present invention is applied to an automated production line, and machines can replace manual labor to complete the upper brushing work of various types of shoes, thereby protecting the health of operators and reducing labor costs.

[0092] The glue coating part 412 is in a columnar body structure.
