Description

Technical Field

[0001] The present invention relates to the field of shoe manufacturing and production, and specifically to a bonding and pressing machine for the sole of a slipper. Background Art

[0002] Slippers are usually formed by bonding a rubber sole and a shoe upper. In order to efficiently bond the sole and the shoe upper and ensure the shape and structural stability of the slipper, it is necessary to apply a certain pressure to the connection between the shoe upper and the sole through a sole pressing machine, so that the glue can fully exert its viscosity between the sole and the shoe upper.

[0003] The existing sole pressing machine mainly consists of a pressing bottom plate and side pressing plates. When pressing the sole and the shoe upper, the worker first places the slipper outside the pressing bottom plate, so that the sole is located under the pressing bottom plate. Then, the pressing bottom plate is driven by a hydraulic cylinder on the upper side to move downward, so that the pressing bottom plate presses the sole against the tabletop, thereby fixing the sole. Then, the side pressing plates on both sides are simultaneously pushed by the hydraulic cylinders on both sides to apply pressure to the connection between the sole and the shoe upper.

[0004] However, when the rubber sole of the slipper is squeezed by the pressing bottom plate, it will extend to both sides, so that the pressing bottom plate cannot completely cover the upper side of the sole. When the side pressing plate squeezes the connection between the sole and the shoe upper, the side pressing plate will squeeze and warp the parts of the sole protruding from the pressing bottom plate on both sides, thereby reducing the pressing effect on the connection between the sole and the shoe upper. And in order to facilitate the worker to quickly pick up and place the slipper on the sole pressing machine, a pressing bottom plate slightly smaller than the width of the sole is usually used, which makes the warping of both sides of the sole during pressing more serious, thus further affecting the pressing effect of the sole and the shoe upper. In addition, the existing sole pressing machine can only perform the steps of feeding, pressing, and discharging in a step-by-step cycle, so that when pressing the sole and the shoe upper, the operation of feeding and discharging cannot be performed, resulting in low pressing efficiency.

Detailed implementation manner

[0029] The embodiments of the present invention will be described in detail below. The embodiments described below are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention. For those not specified in the embodiments regarding specific technologies or conditions, they shall be carried out according to the technologies or conditions described in the literature in this field or according to the product specifications.

[0030] Refer to Figure 1 and Figure 2 , a bonding and pressing machine for the sole of a slipper, comprising an operating platform 1, a U-shaped plate 2 is fixedly installed at the rear part of the upper side of the operating platform 1, a first hydraulic rod 3 is fixedly installed on the upper side of the U-shaped plate 2, second hydraulic rods 4 are fixedly installed on the left and right sides of the U-shaped plate 2 symmetrically, side extrusion plates 5 are slidably arranged along the left and right directions on the left and right side walls of the U-shaped plate 2 through guide columns, the side extrusion plates 5 are fixedly connected to the telescopic sections of the corresponding second hydraulic rods 4, a rotating column 6 is rotatably arranged in the middle of the operating platform 1, a square rod 7 is fixedly installed on the upper part of the rotating column 6, and a limiting mechanism 8 for limiting the slipper is arranged on the square rod 7 and the rotating column 6 together.

[0031] When it is necessary to press the sole and the upper of the slipper, the operator first places the slipper inside the limiting mechanism 8, then moves the slipper to the inside of the U-shaped plate 2 through the limiting mechanism 8, and then extends the telescopic section of the first hydraulic rod 3 to drive the limiting mechanism 8 to press the sole of the slipper on the operating platform 1, and at the same time, the limiting mechanism 8 can automatically adapt to the width of the sole of the slipper.

[0032] Then the operator places the slippers to be pressed inside the limiting mechanism 8 again. When the limiting mechanism 8 squeezes the soles of the slippers onto the operating table 1, the limiting mechanism 8 can adapt to the deformed and expanded soles again according to the squeezing force of the slippers, and then extends the telescopic sections of the two No. 2 hydraulic rods 4, so that the No. 2 hydraulic rods 4 drive the side squeezing plates 5 to squeeze on the connection between the soles and the uppers of the slippers, thereby pressing the slippers. After the pressing is completed, the limiting mechanism 8 drives the rotating column 6 to rotate half a circle, so that the slippers to be pressed on the limiting mechanism 8 and the pressed slippers are exchanged.

[0033] See also Figure 1 and Figure 5 The limiting mechanism 8 includes two supporting plates 81 symmetrically arranged on the square rod 7, the supporting plates 81 are slidably connected to the square rod 7 in the vertical direction, a coil spring is arranged between the rotating column 6 and the supporting plate 81, an L-shaped plate 82 is fixedly installed on the middle part of the upper side of the supporting plate 81, and the lateral section of the L-shaped plate 82 faces the direction away from the axis of the rotating column 6. Two symmetrically arranged expansion plates 83 are arranged on the side of the supporting plate 81 away from the axis of the rotating column 6, and the expansion plate 83 is slidably connected to the supporting plate 81 along the width direction through the support plate thereon.

[0034] Continue reading Figure 1 and Figure 5 The limiting mechanism 8 also includes a moving component 84 for pushing and pulling the expansion plate 83. The moving component 84 includes a moving square rod 841 that slides along the length direction of the supporting plate 81 and is inserted into the vertical section of the L-shaped plate 82. A tension spring is arranged between the moving square rod 841 and the vertical section of the L-shaped plate 82 at the corresponding position. A connecting plate 842 is hinged on the upper side of the support plate of the expansion plate 83 away from the axis of the rotating column 6. The two connecting plates 842 at the same supporting plate 81 are hinged to the moving square rod 841 at the corresponding position at one end close to the axis of the rotating column 6.

[0035] In the initial state, the two supporting plates 81 are arranged front and back, and the rear supporting plate 81 drives the L-shaped plate 82 thereon to be located at the lower part of the No. 1 hydraulic rod 3. In the initial state, the tension spring drives the movable square rod 841 to move toward the direction close to the axis of the rotating column 6 through its own tension, so that the movable square rod 841 drives the corresponding two expansion plates 83 to be close to the supporting plate 81 through the two connecting plates 842 connected to it, thereby shortening the distance between the two expansion plates 83 on the same supporting plate 81, making it convenient for the operator to place the slippers on the outside of the supporting plate 81.

[0036] Continue reading Figure 1 and Figure 5An anti-drop component 85 is provided on the L-shaped plate 82 and the operating table 1. The anti-drop component 85 includes a blocking square rod 851 which is slidably arranged in the vertical direction on the side of the L-shaped plate 82 away from the axis of the rotating column 6. A semicircular magnetic block 852 is fixedly installed on the upper part of the blocking square rod 851. A fixing frame 853 is fixedly installed on the upper left front part of the operating table 1. A spiral metal plate 854 is fixedly installed on the lower part of the fixing frame 853 close to the axis of the rotating column 6.

[0037] Continue reading Figure 1 and Figure 5 The spiral metal plate 854 is in a quarter arc structure, the center of the spiral metal plate 854 is located on the axis of the rotating column 6, the end of the spiral metal plate 854 close to the shaped plate 2 is lower than the other end, and the end of the spiral metal plate 854 away from the shaped plate 2 is located directly in front of the rotating column 6.

[0038] In the initial state, the front support plate 81 drives the blocking square rod 851 at the corresponding position to be located on the front lower side of the spiral metal plate 854 through the L-shaped plate 82 thereon, and at the same time, the magnetic block 852 is adsorbed on the lower side of the spiral metal plate 854, so that the magnetic block 852 adsorbed on the spiral metal plate 854 drives the blocking square rod 851 at the corresponding position to move upward relative to the L-shaped plate 82, so that the blocking square rod 851 does not block the vertical section of the L-shaped plate 82. When the slippers need to be pressed together, the operator places the slippers on the outside of the front support plate 81, so that the slipper cover is arranged on the outside of the support plate 81 and the two expansion plates 83 thereon, and at the same time, the sole of the slippers is located on the lower side of the front support plate 81 and the two expansion plates 83 thereon.

[0039] See also Figure 1 and Figure 2 The limiting mechanism 8 also includes a rotating component 86, which includes a groove 861 opened on the left side wall of the operating table 1, and an execution motor 862 is fixedly installed inside the groove 861. The output shaft of the execution motor 862 is connected to the rotating column 6 through a belt 863. The rotating column 6 and the operating table 1 are jointly provided with a fixed angle component 864 for limiting the angle of each rotation of the rotating column 6.

[0040] When the operator places the slippers on the outside of the front support plate 81, the execution motor 862 is started to drive the rotating column 6 to rotate. The rotating column 6 drives the two support plates 81 to rotate synchronously through the square rod 7, so that the front support plate 81 drives the slippers thereon to rotate to the rear side in the direction away from the spiral metal plate 854. When the front support plate 81 rotates, the front support plate 81 drives the blocking square rod 851 at the corresponding position through the L-shaped plate 82 thereon to gradually rotate to the right side of the spiral metal plate 854, so that the blocking square rod 851 drives the magnetic block 852 thereon to rotate until it is not in contact with the spiral metal plate 854, so that the blocking square rod 851 falls to the front side of the corresponding L-shaped plate 82 under the action of gravity, and then the blocking square rod 851 blocks the upper part of the slippers to prevent the rotating support plate 81 from throwing the slippers out.

[0041] And when the rear support plate 81 rotates from the direction close to the spiral metal plate 854 to the lower side of the spiral metal plate 854, the rear support plate 81 drives the magnetic block 852 thereon to contact the rear end of the spiral metal plate 854, and then the rear support plate 81 drives the magnetic block 852 to continue to rotate forward, so that the magnetic block 852 gradually rises along the lower side of the spiral metal plate 854, and then the magnetic block 852 on the rear support plate 81 drives the blocking square rod 851 at the corresponding position to move up to a position where it does not block the vertical section of the L-shaped plate 82, so that the operator can place the slippers to be pressed on the rear support plate 81.

[0042] See also Figure 2 , Figure 3 and Figure 4 The fixed angle assembly 864 includes a follower ring plate 8641 which is slidably arranged on the upper outer side of the rotating column 6, a resisting spring is arranged between the follower ring plate 8641 and the rotating column 6, two sliders 8642 are arranged at equal intervals along the circumference of the follower ring plate 8641, the sliders 8642 are slidably connected with the follower ring plate 8641 along the circumference, an arc groove 8643 corresponding to the slider 8642 is opened on the follower ring plate 8641, a blocking column 8644 sliding in the arc groove 8643 is fixedly installed on the upper part of the slider 8642, an active spring is arranged between the slider 8642 and the follower ring plate 8641, a limit block 8645 is fixedly installed on the left upper part of the operating table 1, and the right side of the limit block 8645 is located on the upper part of the follower ring plate 8641.

[0043] In the initial state, the active spring pushes the slider 8642 to move by its own elastic force, so that the slider 8642 drives the blocking column 8644 thereon along the arc groove 8643 to the end of the arc groove 8643 away from the active spring. The blocking column 8644 located on the side close to the limit block 8645 is at the front side of the limit block 8645 in the initial state. When the rotating column 6 rotates, the rotating column 6 drives the follower ring plate 8641 to rotate synchronously, and the follower ring plate 8641 rotates synchronously with the blocking column 8644 through the two sliders 8642 of the active spring.

[0044] When the rotating column 6 rotates half a circle, the rotating column 6 drives the blocking column 8644, which was originally far away from the position of the limit block 8645, to rotate until it is close to the rear side of the limit block 8645, and the reaction force of the limit block 8645 on the blocking column 8644 pushes the blocking column 8644 to move to the end of the arc groove 8643 close to the active spring, and at the same time compresses the active spring, so that the limit block 8645 blocks the rotation of the rotating column 6 through the blocking column 8644, which facilitates the rotating column 6 to quickly rotate half a circle, thereby reducing the rotation time and improving the pressing efficiency.

[0045] See also Figure 5 and Figure 6 The moving component 84 also includes a rectangular groove 843 opened on the side of the supporting plate 81 close to the axis of the rotating column 6, a rectangular frame 844 is slidably arranged inside the rectangular groove 843 along the length direction of the supporting plate 81, and an active push plate 845 is slidably arranged inside the rectangular frame 844 along the vertical direction. The lower side of the active push plate 845 is slidably connected to the rotating column 6, and the upper side of the active push plate 845 is provided with an inclined surface which gradually inclines from bottom to top toward the direction close to the axis of the rotating column 6.

[0046] See also Figure 5 , Figure 6 and Figure 7 An adjustment block 846 is slidably provided inside the rectangular groove 843 along the length direction of the supporting plate 81. The adjustment block 846 is located on the side of the rectangular frame 844 in the same rectangular groove 843 close to the axis of the rotating column 6. A No. 1 screw 847 is rotatably provided on the adjustment block 846. The No. 1 screw 847 is threadedly connected to the rectangular frame 844 in the same rectangular groove 843. A right-angled trapezoidal block 848 is slidably provided on the side wall of the rectangular groove 843 close to the axis of the rotating column 6 along the vertical direction. The inclined surface of the right-angled trapezoidal block 848 is slidably connected to the adjustment block 846.

[0047] See also Figure 6 and Figure 7A return spring is arranged between the right-angled trapezoidal block 848 and the supporting plate 81, and a bottom plate 849 is arranged on the lower part of the right-angled trapezoidal block 848 to slide in the vertical direction through a guide rod, and a No. 2 screw 840 is rotatably arranged on the bottom plate 849, and the No. 2 screw 840 is threadedly connected to the right-angled trapezoidal block 848. The inclined surface of the right-angled trapezoidal block 848 is a structure that gradually inclines from bottom to top toward the direction close to the axis of the rotating column 6, and the length of the lower base of the right-angled trapezoidal block 848 is equal to its height, and the length of the upper base of the right-angled trapezoidal block 848 is equal to half of its height.

[0048] In the initial state, the return spring pushes the right-angled trapezoidal block 848 downward by its own elastic force, so that the lower side of the right-angled trapezoidal block 848 is flush with the lower side of the supporting plate 81. At the same time, the right-angled trapezoidal block 848 pulls the adjustment block 846 in the direction close to the axis of the rotating column 6 through its inclined surface, so that the position of the adjustment block 846 in the initial state is fixed. The operator turns the No. 1 screw 847 with the Allen wrench according to the width of the sole in advance, so that the No. 1 screw 847 drives the rectangular frame 844 relative to the adjustment block 846 moves along the rectangular groove 843, and the rectangular frame 844 drives the active push plate 845 inside it to move synchronously, so that the active push plate 845 moves to a suitable position on the lower side of one end of the movable square rod 841 close to the axis of the rotating column 6. The operator pre-rotates the No. 2 screw 840 with an Allen wrench according to the thickness of the sole, so that the No. 2 screw 840 drives the bottom plate 849 to move downward, so that the distance between the lower side surface of the bottom plate 849 and the lower side surface of the supporting plate 81 is equal to the thickness of the sole.

[0049] Then, the telescopic section of the No. 1 hydraulic rod 3 is extended to abut against the upper side of the horizontal section of the L-shaped plate 82 at the corresponding position, so that the No. 1 hydraulic rod 3 drives the supporting plate 81 located at the position of the L-shaped plate 2 to move downward through the L-shaped plate 82, and the L-shaped plate 82 and the supporting plate 81 simultaneously drive the expansion plate 83, the movable square rod 841 and the connecting plate 842 thereon to move downward, so that the side of the movable square rod 841 close to the axis of the rotating column 6 moves downward to the inclined surface of the active push plate 845, so that the active push plate 845 pushes the movable square rod 841 in the direction away from the axis of the rotating column 6, and the movable square rod 841 pushes the expansion plate 83 in the direction away from the supporting plate 81 through the connecting plate 842, thereby making the two expansion plates 83 on the same supporting plate 81 move to the position corresponding to the width of the slippers sole.

[0050] The supporting plate 81 and the expansion plate 83 jointly drive the sole of the slippers onto the operating table 1, and the supporting plate 81 and the expansion plate 83 move downward to rest against the upper side of the sole. At this time, the supporting plate 81 drives the bottom contact plate 849 to rest against the operating table 1 through the right-angle trapezoidal block 848, and then continues to extend the telescopic section of the No. 1 hydraulic rod 3, so that the supporting plate 81 and the expansion plate 83 squeeze the sole, thereby fixing the sole on the operating table 1. At the same time, the sole is squeezed by the supporting plate 81 and the expansion plate 83, and the thickness becomes smaller and the width becomes larger.

[0051] When the supporting plate 81 and the expansion plate 83 squeeze the sole, the reaction force of the operating table 1 on the bottom contact plate 849 pushes the bottom contact plate 849 upward, so that the bottom contact plate 849 drives the right-angled trapezoidal block 848 to move upward relative to the supporting plate 81, and the right-angled trapezoidal block 848 pushes the adjustment block 846 in the direction away from the axis of the rotating column 6. The adjustment block 846 drives the expansion plates 83 on both sides to move synchronously with the expansion of the sole through the rectangular frame 844, the active push plate 845, the movable square rod 841, and the connecting plate 842 in sequence, so that the expansion plate 83 can prevent the two sides of the sole from curling up.

[0052] It should be noted that since the length of the lower base of the right-angled trapezoidal block 848 is equal to its height, and the length of the upper base of the right-angled trapezoidal block 848 is equal to half of its height, the displacement of the adjustment block 846 pushed by the right-angled trapezoidal block 848 is equal to half of the upward displacement of the right-angled trapezoidal block 848, so that the right-angled trapezoidal block 848 can evenly convert the upward displacement into the displacement of the two expansion plates 83, so that the expansion plates 83 can change with the change of the sole width.

[0053] When the supporting plate 81 and the expansion plate 83 are pressing the sole, the operator simultaneously places the slippers to be pressed on the supporting plate 81 away from the side of the shaped plate 2, so that the pressing operation is carried out simultaneously with the loading and unloading operation, thereby increasing the pressing efficiency.

[0054] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The fixed angle assembly 864 also includes an L-shaped push plate 8646 that is slidably arranged on the upper part of the operating table 1 in the vertical direction. The front end of the longitudinal section of the push plate 8646 is rotatably connected to the follower ring plate 8641. A triangular block 8647 is fixedly installed on the upper left part of the transverse section of the push plate 8646. The triangular block 8647 is located on the right side of the side extrusion plate 5 on the left side.

[0055] When the supporting plate 81 and the expansion plate 83 squeeze the sole onto the operating table 1, the telescopic sections of the two No. 2 hydraulic rods 4 are extended at the same time to drive the two side squeezing plates 5 to squeeze the positions on both sides of the sole, thereby pressing the connection between the sole and the upper through the side squeezing plates 5.

[0056] When the side extrusion plate 5 on the left moves to the right, the side extrusion plate 5 contacts the inclined surface of the triangular block 8647, so that the side extrusion plate 5 pushes the triangular block 8647 downward, and the triangular block 8647 drives the follower ring plate 8641 to move downward through the pushing plate 8646, and the follower ring plate 8641 drives the blocking column 8644 to move downward to the lower side of the limit block 8645 through the slider 8642, so that the limit block 8645 no longer blocks the blocking column 8644, and then the active spring pushes the blocking column 8644 to move to the corresponding arc groove 8643 away from the end of the resisting spring through its own elastic force, and at the same time makes the blocking column 8644 move to the front side of the limit block 8645, so that the rotating column 6 can rotate again.

[0057] See also Figure 1-Figure 7 When pressing the slippers, the present invention also includes the following steps: In the first step, the operator places the slippers on the outside of the front supporting plate 81, so that the slipper cover is arranged on the outside of the supporting plate 81 and the two expansion plates 83 thereon, and at the same time makes the slipper sole located on the lower side of the front supporting plate 81, and starts the execution motor 862 to drive the rotating column 6 to rotate, so that the front supporting plate 81 drives the slippers thereon to rotate to the rear side in the direction away from the spiral metal plate 854.

[0058] In the second step, the support plate 81 on the rear side drives the magnetic block 852 thereon to contact the rear end of the spiral metal plate 854, so that the magnetic block 852 drives the blocking square rod 851 at the corresponding position to move up to a position where it does not block the vertical section of the L-shaped plate 82, making it convenient for the operator to place the slippers to be pressed on the support plate 81 on the rear side.

[0059] In the third step, the rotating column 6 drives the blocking column 8644 to rest against the limit block 8645, and at the same time compresses the active spring, so that the limit block 8645 blocks the rotation of the rotating column 6 through the blocking column 8644, making it easier for the rotating column 6 to quickly rotate half a circle, thereby reducing the rotation time and improving the pressing efficiency.

[0060] In the fourth step, the telescopic section of the No. 1 hydraulic rod 3 is then extended to rest against the upper side of the horizontal section of the L-shaped plate 82 at the corresponding position, so that the No. 1 hydraulic rod 3 drives the supporting plate 81 to move downward through the L-shaped plate 82, so that the side of the moving square rod 841 close to the axis of the rotating column 6 moves downward to the inclined surface of the active push plate 845, so that the active push plate 845 moves to the position corresponding to the width of the slipper sole by pushing the two expansion plates 83 of the moving square rod 841.

[0061] In the fifth step, the supporting plate 81 and the expansion plate 83 jointly drive the sole of the slippers onto the operating table 1 and squeeze the sole so that the thickness of the sole becomes smaller and the width becomes larger due to the squeezing of the supporting plate 81 and the expansion plate 83. At the same time, the bottom contact plate 849 drives the expansion plates 83 on both sides to move synchronously with the expansion of the sole, so that the expansion plate 83 can prevent the two sides of the sole from curling up.

[0062] In the sixth step, the telescopic sections of the two No. 2 hydraulic rods 4 are extended at the same time to drive the two side extrusion plates 5 to squeeze the positions on both sides of the sole, so that the connection between the sole and the upper is pressed by the side extrusion plates 5. When the supporting plate 81 and the expansion plate 83 squeeze the sole, the operator simultaneously places the slippers to be pressed on the supporting plate 81 away from the side of the shaped plate 2, so that the pressing operation is carried out simultaneously with the loading and unloading operation, thereby improving the pressing efficiency.

A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention and they are still covered by the protection scope of the present invention.
