Description

Technical Field

[0001] The utility model relates to the technical field of punching devices, and particularly relates to a shoe upper punching device. Background Art

[0002] The shoe upper means the vamp, the surface above the sole, the part covering the instep. The shoe upper is usually made of natural leather, super fiber (fiber leather), PU space leather, mesh cloth, canvas and other materials.

[0003] During the production process of the shoe upper, it is necessary to punch the shoe string holes on the shoe upper through a punching machine. First, the unperforated shoe upper needs to be placed on the workbench, and the position of the punch of the punching machine is adjusted so that its position corresponds to the shoe string holes on the shoe upper, and then the subsequent batch of shoe uppers can be punched.

[0004] However, when punching a batch of shoe uppers traditionally, it is impossible to position the position of the shoe upper placed on the workbench, so that it is difficult for the position of the shoe string holes to correspond to the punch of the punching machine when placing the shoe upper subsequently, and the phenomenon of shoe string hole deviation is likely to occur during punching, thus reducing the production yield of the shoe upper. Content of the Utility Model

[0005] The purpose of the utility model is to provide a shoe upper punching device aiming at the defects and deficiencies of the prior art.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions: a shoe upper punching device, including a frame, a workbench arranged on the upper end surface of the frame, a driving frame arranged on the upper end of the frame above the workbench, a lifting plate arranged at the lower end of the driving frame above the workbench, a plurality of punching heads adjustably arranged at the lower end of the lifting plate, a lifting device arranged on the driving frame and connected to the upper end of the lifting plate for driving the lifting plate to descend or ascend, and further including a right limiting block arranged on the upper end surface of the workbench, a right blocking block arranged at the right end of the right limiting block, a side limiting block arranged on the upper end surface of the workbench on the left side of the right limiting block, and two side blocking blocks respectively arranged at the front and rear ends of the side limiting block.

[0007] Further improvement is that: a right adjusting member for horizontally adjusting the position of the right blocking block on the right limiting block is arranged between the right limiting block and the right blocking block.

[0008] Further improvement is as follows: The right regulating member includes a right sliding groove formed on the right end face of the right limiting block, a right sliding rod with its left end slidably disposed on the right limiting block within the right sliding groove and its right end fixedly connected to the left end face of the right blocking block, a right waist-shaped hole formed on the upper end face of the right limiting block and communicating with the right sliding groove, a right connecting rod vertically disposed at the upper end of the right sliding rod and in clearance fit with the right waist-shaped hole, and a right nut threadedly connected to the upper end of the right connecting rod and located on the upper end face of the right limiting block.

[0009] Further improvement is as follows: Side-end regulating members are respectively disposed between the two side blocking blocks and the side-end limiting block for obliquely adjusting the positions of the two side blocking blocks on the side-end limiting block.

[0010] Further improvement is as follows: The side-end regulating member includes two obliquely arranged inclined sliding grooves symmetrically formed at the front and rear ends of the side-end limiting block, two inclined sliding rods with one end respectively slidably disposed on the side-end limiting block within the inclined sliding grooves and the other end fixedly connected to the upper end face of the side blocking block, two inclined waist-shaped holes symmetrically formed on the upper end face of the side-end limiting block and respectively communicating with the two inclined sliding grooves, two side connecting rods respectively disposed at the upper ends of the two inclined sliding rods and in clearance fit with the inclined waist-shaped holes, and two side nuts respectively threadedly connected to the upper ends of the two side connecting rods and located on the upper end face of the side-end limiting block.

[0012] Further improvement is as follows: The two side blocking blocks are arc-shaped blocks.

[0013] Further improvement is as follows: The lifting device includes a longitudinal sliding hole longitudinally formed on the driving frame, a longitudinal sliding rod liftably disposed on the driving frame within the longitudinal sliding hole, an installation slot formed on the driving frame and communicating with the longitudinal sliding hole, a rotating shaft rotatably disposed on the driving frame within the installation slot, an avoidance opening formed on the longitudinal sliding rod near the end face of the installation slot, first engaging teeth longitudinally and equidistantly arranged on the longitudinal sliding rod within the avoidance opening, second engaging teeth annularly and equidistantly arranged on the outer periphery of the rotating shaft and meshing with the first engaging teeth for driving the longitudinal sliding rod to descend or ascend within the longitudinal sliding hole when the rotating shaft rotates forward or backward, and a servo rotating motor with its fixed end disposed on the driving frame and its output end connected to the rotating shaft for driving the rotating shaft to rotate forward or backward.

[0014] After adopting the above technical solution, the beneficial effects of the present utility model are as follows: When it is necessary to punch the shoe upper in batches, first place a shoe upper on the upper end surface of the workbench, put the left opening and the right opening of the shoe upper on the outer sides of the side end limiting block and the right limiting block respectively. The right limiting block limits the rightmost end of the right opening. Then, pull the left side of the shoe upper so that the inner sides of the left opening are in contact with the two side blocks respectively, thereby limiting the left opening of the shoe upper. At this time, adjust the position of the punching head to make the punching head correspond to the position of the shoelace hole.

[0015] Further effect: When it is necessary to adjust the position of the right block according to the length of the right opening of the shoe upper so that the right block can position the right end face of the right opening, use a tool to reverse-twist the right nut to rise on the right connecting rod, so that the right nut no longer abuts against the upper end face of the right limiting block, thereby releasing the sliding fixation of the right connecting rod. At this time, horizontally push the right connecting rod to drive the right sliding rod to move horizontally in the right sliding groove, thereby driving the right block to be adjusted according to the position of the right end face of the right opening. After adjustment, use the tool to forward-twist the right nut again so that the right nut abuts against the upper end face of the right limiting block, thereby fixing the right connecting rod in the right waist-shaped hole to fix the position of the right block.

[0016] Further effect: When it is necessary to adjust the position of the side blocks according to the width of the left opening of the shoe upper so that the two side blocks can position the left opening, use a tool to reverse-twist the two side nuts so that the two side nuts no longer abut against the upper end face of the side end limiting block, thereby releasing the sliding fixation of the side connecting rod. At this time, push the side connecting rod in an inclined direction to drive the inclined sliding rod to move in an inclined direction in the inclined sliding groove, thereby driving the side blocks to be adjusted according to the width of the left opening. After adjustment, use the tool to forward-twist the side nuts again so that they abut against the upper end face of the side end limiting block, thereby fixing the side connecting rod in the inclined waist-shaped hole to fix the positions of the two side blocks.

[0027] A right adjusting member is arranged between the right limiting block 6 and the right blocking block 7 for horizontally adjusting the position of the right blocking block 7 on the right limiting block 6.

[0028] The right adjusting member includes a right sliding groove 10 opened on the right end surface of the right limiting block 6, a right sliding rod 11 with its left end slidably arranged in the right sliding groove 10 on the right limiting block 6 and its right end fixedly connected to the left end surface of the right blocking block 7, a right waist-shaped hole 12 opened on the upper end surface of the right limiting block 6 and communicating with the right sliding groove 10, a right connecting rod 13 vertically arranged at the upper end of the right sliding rod 11 and in clearance fit with the right waist-shaped hole 12, and a right nut 14 threadedly connected to the upper end of the right connecting rod 13 and located on the upper end surface of the right limiting block 6.

[0029] Side end adjusting members are respectively arranged between the two side blocking blocks 9 and the side end limiting block 8 for obliquely adjusting the positions of the two side blocking blocks 9 on the side end limiting block 8.

[0030] The side end adjusting member includes two inclined sliding grooves 15 symmetrically opened at the front and rear ends of the side end limiting block 8 and obliquely arranged, two inclined sliding rods 16 with one end respectively slidably arranged in the inclined sliding grooves 15 on the side end limiting block 8 and the other end fixedly connected to the upper end surface of the side blocking block 9, two inclined waist-shaped holes 17 symmetrically opened on the upper end surface of the side end limiting block 8 and respectively communicating with the two inclined sliding grooves 15, two side connecting rods 18 respectively arranged at the upper ends of the two inclined sliding rods 16 and in clearance fit with the inclined waist-shaped holes 17, and two side nuts 19 respectively threadedly connected to the upper ends of the two side connecting rods 18 and located on the upper end surface of the side end limiting block 8.

[0034] The working principle of the present utility model: When it is necessary to punch the shoe upper in batches, first place a shoe upper on the upper end surface of the workbench 2, sleeved the left opening and the right opening of the shoe upper on the outer sides of the side end limiting block 8 and the right limiting block 6 respectively, limit the rightmost end of the right opening through the right limiting block 6, and then pull the left side of the shoe upper so that the inner side surfaces of the left opening are in contact with the two side blocking blocks 9 respectively, thereby limiting the left opening of the shoe upper. At this time, adjust the position of the punching head 5 to make the punching head 5 correspond to the position of the shoelace hole. During subsequent punching processing, the position of the shoe upper placed on the table can be positioned, and the position of the shoelace hole can correspond to the position of the punching head 5 during subsequent placement of the shoe upper, so that it is not easy to have the phenomenon of shoelace hole offset during punching processing, thereby improving the production yield of the shoe upper;

[0035] When it is necessary to adjust the position of the right blocking block 7 according to the length of the right opening of the shoe upper so that the right blocking block 7 can position the right end face of the right opening, reverse the tool to screw the right nut 14 up on the right connecting rod 13 so that the right nut 14 no longer abuts against the upper end face of the right limiting block 6, thereby releasing the sliding fixation of the right connecting rod 13. At this time, horizontally push the right connecting rod 13 to drive the right sliding rod 11 to move horizontally in the right sliding groove 10, thereby driving the right blocking block 7 to be adjusted according to the position of the right end face of the right opening. After the adjustment is completed, then screw the right nut 14 forward with the tool so that the right nut 14 abuts against the upper end face of the right limiting block 6, thereby fixing the right connecting rod 13 in the right waist-shaped hole 12 to fix the position of the right blocking block 7;

[0036] When it is necessary to adjust the position of the side stoppers 9 according to the width of the left opening of the shoe upper so that the two side stoppers 9 can position the left opening, use a tool to reverse-twist the two side nuts 19 so that the two side nuts 19 no longer abut against the upper end surface of the side end limit block 8, thereby releasing the sliding fixation of the side connecting rod 18. At this time, push the side connecting rod 18 in an inclined direction to drive the inclined sliding rod 16 to move in the inclined sliding groove 15 in an inclined direction, thereby driving the side stopper 9 to be adjusted according to the width of the left opening. After the adjustment is completed, use a tool to forward-twist the side nut 19 so that it abuts against the upper end surface of the side end limit block 8, thereby fixing the side connecting rod 18 in the inclined waist-shaped hole 17 to fix the positions of the two side stoppers 9;

[0037] The arc surface can reduce the damage of the right stopper 7 to the shoe upper; the arc-shaped block can increase the contact area between the side stopper 9 and the shoe upper and reduce the damage of the side stopper 9 to the shoe upper;

[0038] When it is necessary to drive the lifting plate 4 to descend so that the punching head 5 punches the shoe upper, drive the rotating shaft 23 to rotate forward through a servo rotating motor (not shown in the figure). When the rotating shaft 23 rotates, it is meshed and connected through the second mating teeth 26 and the first mating teeth 25, thereby driving the longitudinal sliding rod 21 to descend in the longitudinal sliding hole 20, so that the lifting plate 4 drives the punching head 5 to descend to perform a punching action on the shoe upper. After the punching is completed, drive the rotating shaft 23 to rotate reversely through a servo rotating motor (not shown in the figure), thereby driving the longitudinal sliding rod 21 to ascend in the longitudinal sliding hole 20.
