[0039] The following describes the specific implementation of the present invention in more detail with reference to specific embodiments:

[0040] See also Figure 1-3 The embodiment of the present invention provides an automatic heel pressing machine, which includes a shoe upper fixing component 100, a flip driving component 200 and a heel pressing component 300. It should be noted that in this embodiment, the operator's preset position is used as the front side of the automatic heel pressing machine, and the following is established: Figure 1 The rectangular coordinate system shown is used to describe the structure of the automatic heel pressing machine in detail.

[0041] Among them, the upper fixing component 100 includes a supporting shaft 110 extending along the front-to-back direction and two upper support platforms 120 arranged on opposite sides of the supporting shaft 110. The upper support platforms 120 are used to support the upper 100' put on the shoe last and the heel placed on the upper at the pressing station; the flip driving component 200 is used to drive the supporting shaft 110 to rotate around the first axis to drive each upper support platform 120 to pass through the pressing station respectively; when the upper support platform 120 is in the pressing station and the upper 100' and the heel are supported by the upper support platform 120, the heel pressing component 300 is on the upper side of the upper support platform 120 and can be used to press the heel down to fix the heel to the upper 100'.

[0042] It should be noted that the support shaft 110 extending in the front-to-back direction can simultaneously support the two upper support platforms 120, and under the drive of the flip drive assembly 200, the support shaft 110 can drive the two upper support platforms 120 to rotate synchronously around a first axis, wherein the first axis coincides with the centerline of the support shaft 110. Preferably, the two upper support platforms 120 are symmetrically arranged with respect to the support shaft 110. When the support shaft 110 drives one of the upper support platforms 120 to rotate to the pressing station, the upper support platform 120 will be relatively on the upper side of the support shaft 110. At this time, the operator can place the shoe last with the upper on the upper support platform 120, and place the heel at the heel position of the upper 100'. When the upper is placed on the upper support platform 120, the sole faces upward. At this time, the upper 100' at the pressing station can be pressed down by the heel pressing assembly 300 to tightly fix the heel to the heel position of the upper 100', thereby achieving the fixation of the upper 100' and the heel. After the upper 100' on the upper support platform 120 completes the heel pressing operation, the support shaft 110 will drive another upper support platform 120 to rotate to the pressing station to facilitate the operator to perform the next heel pressing operation. At the same time, the upper support platform 120 with the fixed upper 100' and heel will be rotated to the lower side of the support shaft 110 under the synchronous drive of the support shaft 110. At this time, the fixed upper 100' and heel will be placed downward and automatically fall under the action of gravity, thereby automatically unloading. This cycle is repeated, and the heel pressing operation of the upper 100' can be continuously performed with a small interruption time.

[0043] In summary, the automatic heel pressing machine provided by the embodiment of the present invention first places the upper 100' on the shoe last before the upper support platform 120 in the pressing position, and places the matching heel at the heel position of the upper 100'. Then, the heel and the upper 100' are pressed down by the heel pressing component 300 to fix the heel and the upper 100'. Then, the other upper support platform 120 is flipped to the pressing position by the flip driving component 200. Based on this, the operator The operator can continue to place the upper 100' and the heel on the upper support platform 120 at the pressing station and perform the heel pressing operation again. At the same time, the upper support platform 120 supporting the pressed upper 100' and heel will be synchronously flipped, and the pressed upper 100' and heel will be placed downward. Based on this, the upper 100' and heel fixed to each other will fall from the upper support platform 120 under the action of gravity to complete automatic unloading. Therefore, the automatic heel pressing machine provided by the embodiment of the present invention can simplify the process of the operator needing to perform the unloading operation in time after the heel is fixed, and can shorten the interval time between two adjacent heel pressing operations to a certain extent, thereby reducing labor costs, reducing labor intensity, and improving heel pressing efficiency, and is suitable for large-scale heel pressing operations.

[0044] See also Figure 1 、 3 -4. In this embodiment, the flip drive assembly 200 includes at least one flip gear 210 sleeved on the support shaft 110, at least one flip rack 220 meshing with the flip gear 210 and extending in the left-right direction, and a flip driver 230 for driving the flip rack 220 to move in the left-right direction. Driven by the flip driver 230, the flip rack 220 can drive the flip rack 220 and the support shaft 110 to rotate about a first axis. It should be noted that the flip driver 230 can drive the flip rack 220 to move in the left-right direction. When the flip rack 220 moves in the left-right direction, the flip gear 210 meshing with the flip rack 220 will rotate relative to the flip rack 220, driven by the flip rack 220, thereby driving the support shaft 110 connected to the flip gear 210 to rotate about the first axis. Therefore, through the configuration of this embodiment, not only can the rotational drive of the support shaft 110 be easily achieved and the support shaft 110 can be ensured to rotate stably around the first axis, but the rotation angle of the support shaft 110 can also be precisely controlled by adjusting parameters such as the length limit of the flip rack 220 and the number of teeth of the flip rack 220 and the flip gear 210, so as to ensure that each upper support platform 120 can accurately reach the pressing station. Preferably, to further ensure and improve the rotation stability of the support shaft 110, this embodiment is provided with two flip gears 210 spaced apart from each other on the support shaft 110, and two corresponding flip racks 220 are provided to mesh with the two flip gears 210.

[0045] See also Figure 1 、 3 -4. In this embodiment, the flip drive assembly 200 further includes a support slider 240 connected to the flip drive 230 and configured to simultaneously support each flip rack 220, and a guide rail 250 extending in the left-right direction and configured to slidably engage with the support slider 240. It should be noted that the guide rail 250 extends in the left-right direction, and when driven by the flip drive 230, the support slider 240 can drive each flip rack 220 supported thereby to synchronously slide back and forth along the guide rail 250. Therefore, based on the configuration of the support slider 240 and the guide rail 250, on the one hand, the maximum travel range of the flip rack 220 can be limited by the length of the guide rail 250, thereby achieving precise control of the rotation angle of the flip gear 210. On the other hand, the extension direction of the guide rail 250 can also guide the movement direction of the flip rack 220, thereby ensuring that the movement direction of the flip rack 220 is always parallel to the left-right direction, thereby ensuring that the rotation axis of the flip gear 210 coincides with the first axis. In other words, this embodiment can improve the control accuracy of the flip drive assembly 200 over the flip rack 220 and flip gear 210 to a certain extent, and ensure the smoothness and reliability of the movement of the flip rack 220 and flip gear 210. In addition, based on the configuration of the guide rail 250 and the support slider 240, the friction of the flip rack 220 during movement can be reduced, thereby further ensuring its smooth movement.

[0046] See also Figure 1 、 3 -4. In this embodiment, the flip drive assembly 200 further includes two flip buffers 260 symmetrically disposed on the left and right sides of the support slider 240. The flip buffers 260 are configured to elastically abut the support slider 240 when the support slider 240 moves to the left and right ends of the guide rail 250. It should be noted that the two flip buffers 260 are disposed on the left and right ends of the guide rail 250 to elastically abut the support slider 240 when the support slider 240 moves to the left and right ends of the guide rail 250. On the one hand, the flip buffers 260 can prevent the support slider 240 from sliding out of the guide range of the guide rail 250, thereby further ensuring the guiding and restraining effect of the guide rail 250 on the support slider 240 and the flip rack 220. On the other hand, the flip buffers 260 can buffer and decelerate the support slider 240 when the support slider 240 moves to the left and right ends of the guide rail 250 under the drive of the flip drive 230, thereby facilitating a quick and stable fixation of the support slider 240.

[0047] See also Figure 1 、 3-4. In this embodiment, the automatic heel pressing machine further includes a toe lifting assembly 400, which includes two toe supports 410 respectively provided on one side of the two upper support platforms 120 facing the support shaft 110, and a lifting driver 420 for driving the toe supports 410 to reciprocate between a supporting position and a waiting position. The distance from the supporting position to the support shaft 110 is greater than the distance from the waiting position to the support shaft 110. When the upper 100' and the heel are supported by the upper support platforms 120 and the toe support 120 is in the supporting position, the toe support 120 can support the front side of the upper 100'. It should be noted that the lifting driver 420 can drive the toe support 410 to gradually approach and eventually abut against the toe of the upper 100' from the waiting position. At this time, the toe support 410 is in the supporting position. When the upper support platform 120 is in the pressing position and the upper 100' and the heel are supported by the upper support platform 120, the toe support 410 is relatively located on the lower side of the toe of the upper 100', so that when the heel pressing component 300 performs heel pressing on the upper 100' placed on the upper support platform 120, the toe of the upper 100' can be supported by the toe support 410, thereby balancing the force on the front and rear ends of the upper 100', avoiding the upper 100' from being tilted up, resulting in the heel and the upper 100' being unsecured, and avoiding the upper 100' from being damaged due to unbalanced force, that is, the heel pressing effect of the automatic heel pressing machine can be further guaranteed, and the quality of the upper 100' produced by it can be guaranteed.

[0048] See also Figure 2 、 5-6. In this embodiment, the heel pressing assembly 300 includes a pressing mold 310 for pressing the heel, a pressing driver 320 for driving the pressing mold 310 to reciprocate in the vertical direction, and an adjustment driver 330 for driving the pressing mold 310 to reciprocate in the front-to-back direction. It should be noted that the shape and size of the pressing mold 310 can be set according to the type of the upper 100'. In this embodiment, the adjustment driver 330 can drive the pressing mold 310 to move back and forth relative to the upper support platform 120, thereby adjusting the front-to-back alignment accuracy of the pressing mold 310 and the upper support platform 120. This ensures that when the upper 100' and the heel supported by the upper support platform 120 are pressed downward, the pressing mold 310 can accurately contact the heel, tightly wrapping and adhering to the upper 100' and the heel, ensuring that the pressing mold 310 has an appropriate contact area and appropriate force application points with the heel, thereby ensuring the heel pressing effect of the heel pressing assembly 300. The downward pressing mold 310 can be driven to move up and down relative to the upper support platform 120 by the downward pressing driver 320, so that the heel pressing operation of the downward pressing mold 310 can be precisely controlled by controlling the moving distance of the downward pressing mold 310, thereby easily and stably realizing the heel pressing operation, and also ensuring and improving the heel pressing effect of the automatic heel pressing machine.

[0049] See also Figure 2 、 5 -6. In this embodiment, the heel pressing assembly 300 further includes at least one pressing buffer 350 connected to the upper side of the pressing mold 310. The pressing buffer 350 is used to cushion the pressing mold 310 when the pressing mold 310 moves to the uppermost position. It should be noted that the pressing buffer 350 is located at the uppermost position within the range of movement of the pressing mold 310 to elastically support the pressing mold 310 when the pressing mold 310 moves to the uppermost position under the drive of the pressing driver 320. Therefore, based on the setting of the downward pressure buffer 350, on the one hand, the moving range of the downward pressure mold 310 can be limited and guaranteed to prevent the downward pressure mold 310 from leaving the driving range of the downward pressure driver 320. On the other hand, when the downward pressure mold 310 moves to the uppermost side, the downward pressure mold 310 can be buffered and decelerated, so that the downward pressure mold 310 can be fixed faster and more stably, and the collision between the downward pressure mold 310 and the downward pressure driver 320 can be avoided, thereby ensuring the service life of the downward pressure mold 310 to a certain extent; on the other hand, on the basis of ensuring the downward pressure effect of the downward pressure mold 310, the reciprocating movement distance of the downward pressure mold 310 can be correspondingly reduced to shorten the time interval between two adjacent heel pressing operations of the downward pressure mold 310, thereby further improving the heel pressing efficiency.

[0050] See also Figure 5-7In this embodiment, the heel pressing component 300 also includes a positioning member 340 connected to the front side of the pressing mold 310 and used to position the pressing mold 310. The positioning member 340 includes a positioning function member 341 for positioning the pressing mold 310, a positioning support member 342 for supporting the positioning function member 341, and a positioning adjustment screw 343 for connecting the positioning support member 342 and the pressing mold 310. The positioning adjustment screw 343 can be used to adjust the distance between the positioning function member 341 and the pressing mold 310. It should be noted here that the heel is relatively higher than the sole of the upper 100'. Therefore, through the setting of the positioning part 340, the pressing depth of the pressing mold 310 can be positioned when the pressing mold 310 presses the heel, that is, the distance between the pressing mold 310 and the sole of the upper 100' can be determined, so that on the basis of ensuring the pressing effect of the pressing mold 310, the pressing depth of the pressing mold 310 can be avoided, resulting in pressure damage to the upper 100', and the pressing mold 310 can be avoided. Excessive pressure on the heel caused by cracks in the heel can be avoided, thereby further ensuring and improving the heel pressing effect of the automatic heel pressing machine, that is, ensuring the quality of the upper 100' produced by it, and further improving the heel pressing efficiency. Specifically, the positioning function part 341 is supported and fixed by the positioning support part 342, and the positional relationship between the positioning function part 341 and the pressing mold 310 can be adjusted by the positioning adjustment screw 343, so that when the pressing mold 310 presses the heel, it can be judged whether the pressing mold 310 has been pressed down to an appropriate depth by whether the positioning function part 341 contacts the shoe upper 100'.

[0051] See also Figure 5-7In this embodiment, the positioning functional component 341 includes a positioning connection portion 3411 for connecting to the positioning support member 342, a positioning interference portion 3412 connected to the positioning connection portion 3411 and used to contact the shoe upper 100' when the pressing mold 310 presses down the heel, and a rolling interference wheel 3413 connected to one end of the positioning interference portion 3412 away from the positioning connection portion 3411 and capable of rotating around a second axis. The cam 3412 is adapted to engage the shoe 100' and engage the support 342 to engage the shoe 100' and engage the support 342 to engage the shoe 100'.

[0052] See also Figure 1 、 3-4. In this embodiment, the automatic heel pressing machine also includes two upper limiting assemblies 500, and the upper limiting assemblies 500 include at least one first abutment buffer 510 provided on one side of the upper support platform 120, at least one second abutment buffer 520 provided on the side of the upper support platform 120 away from the first abutment buffer 510, and a limiting abutment driver 530 for driving the first abutment buffer 510 and the second abutment buffer 520 to move toward or away from the upper support platform 120. The first abutment buffer 510 and the second abutment buffer 520 are jointly used to elastically abut the upper 100' when the upper support platform 120 is in the pressing position and the upper 100' is supported by the upper support platform 120. It should be noted here that one upper support platform 120 is correspondingly provided with an upper limiting component 500. When the upper support platform 120 is in the pressing position and the upper 100' is supported by the upper support platform 120, the limiting abutment driver 530 can drive the first abutment buffer 510 and the second abutment buffer 520 to move toward each other relative to the upper support platform 120 until the first abutment buffer 510 and the second abutment buffer 520 jointly elastically abut the upper 100' placed on the upper support platform 120. Based on this, the first abutment buffer 510 and the second abutment buffer 520 can maintain a relatively fixed state of the upper, so that when the heel pressing component 300 presses the upper 100', the upper 100' can be prevented from having a poor fixation effect on the heel and the upper 100' due to lateral displacement.

[0053] It should also be noted here that when the support shaft 110 drives the fixed upper and the corresponding upper support platform 120 to rotate around the first axis, the first abutment buffer 510 and the second abutment buffer 520 still maintain the relatively fixed state of the upper 100' until the other upper support platform 120 rotates to the pressing station and the support shaft 110 stops rotating. The first abutment buffer 510 and the second abutment buffer 520 release their abutting force on the upper 100' to facilitate the upper falling from the upper support platform 120. Based on this, the upper 100' can be prevented from falling off the upper support platform 120 during the rotation process, thereby reducing the unloading height of the upper 100' to a certain extent, and allowing the heel of the upper 100' to land first relative to other parts, thereby further ensuring and improving the quality of the upper 100' produced.

[0054] See also Figure 1-2In this embodiment, the automatic heel pressing machine further includes a shoe upper feeding assembly 600, which includes a shoe upper conveyor belt 610 disposed on the underside of the shoe upper fixing assembly 100 and configured to receive shoe uppers dropped from the shoe upper support platform 120, a first conveyor driver 620 configured to drive the shoe upper conveyor belt 610 to move up and down relative to the shoe upper fixing assembly 100, and a second conveyor driver 630 configured to drive the shoe upper conveyor belt 610 to move left and right relative to the shoe upper fixing assembly 100. It should be noted that by driving the shoe upper conveyor belt 610 up and down relative to the shoe upper fixing assembly 100 by the first conveyor driver 620, the distance between the shoe upper conveyor belt 610 and the shoe upper support platform 120 can be adjusted, thereby adjusting the height to which the shoe upper 100' falls when dropped from the shoe upper support platform 120, thereby further ensuring and improving the quality of the produced shoe upper 100'. The upper conveyor belt 610 is driven by the second conveying driver 630 to move left and right relative to the upper fixing assembly 100. On the one hand, the alignment accuracy of the upper conveyor belt 610 and the upper fixing assembly 100 can be adjusted to ensure that the upper conveyor belt 610 can accurately and without omission receive the upper 100'. On the other hand, the conveying position of the upper conveyor belt 610 to the upper 100' can be adjusted accordingly, so that the upper 100' can be accurately collected to the discharge position under the conveyance of the upper conveyor belt 610.

[0055] The automatic heel pressing machine provided by the embodiment of the present invention first places the upper 100' on the shoe last before the upper support platform 120 in the pressing position, and an adapted heel is placed at the heel position of the upper 100'. Then, the heel and the upper 100' are pressed down by the heel pressing component 300 to fix the heel and the upper 100'. Then, the other upper support platform 120 is flipped to the pressing position by the flip driving component 200. Based on this, the operator can continue to place the upper 100' and the heel on the upper support platform 120 in the pressing position, and perform the heel pressing operation again. At the same time, the upper support platform 120 supporting the pressed upper 100' and heel will be flipped synchronously, and the pressed upper 100' and heel will be set downward. Based on this, the upper 100' and the heel fixed to each other will fall from the upper support platform 120 under the action of gravity to complete automatic unloading. Therefore, the automatic heel pressing machine provided by the embodiment of the present invention can simplify the process of the operator needing to perform the material cutting operation in time after the heel is fixed, and can shorten the interval time between two adjacent heel pressing operations to a certain extent, thereby reducing labor costs, reducing labor intensity, and improving heel pressing efficiency, and is suitable for large-scale heel pressing operations.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
