Technical Field

[0001] This application relates to the technical field of rubber shoe production, and particularly to a bonding machine for rubber shoe production. Background Art

[0002] As a type of footwear for daily wear, the production process of rubber shoes involves multiple technological steps, among which applying glue and pressing are key links.

[0003] The bonding process of the sole and upper mainly relies on manual operation: First, workers apply glue to the top periphery of the inner side of the sole and the bottom periphery of the outer side of the upper with a shoe last. Then, the upper is placed on the sole and aligned. Subsequently, pressure is applied to the bonding area between the sole and the upper by both hands and maintained for a period of time to initially cure and shape the glue. Then, the shoes are placed in a heating device to further cure the glue.

[0004] Regarding the above related technology, the bonding process is time-consuming, requires workers to continuously apply pressure, has a high labor intensity, and insufficient production efficiency. Utility Model Content

Detailed implementation manners

[0039] The following will further describe the present application in detail Figures 1-4 in conjunction with the attached drawings.

[0040] An embodiment of the present application discloses an adhesive machine for rubber shoe production. Referring to Figure 1 , the adhesive machine includes a machine table 1, a positioning frame 2, a positioning device 3, a fixing device 4, and a driving device 5. The machine table 1 mainly functions to install equipment. The positioning frame 2 is fixedly installed on the panel of the machine table 1 by bolts or the like, and is used to place the sole. The sole can be clamped and fixed in the positioning frame 2 through the positioning device 3; the fixing device 4 is arranged above the positioning frame 2, and the fixing device 4 is used to clamp and fix the shoe last, thereby fixing the upper. The driving device 5 can drive the fixing device 4 and the upper to move up and down, thereby driving the fixing device 4 and the upper to move downward, bonding the upper and the sole, and applying pressure to the upper through the fixing device 4 to make the sole and the upper tightly adhered.

[0041] Referring to Figure 1 and Figure 2 , specifically, the positioning frame 2 is integrally arranged as a rectangular frame body with a hollow interior and an open upper end. A positioning groove 21 is formed on the inner bottom wall of the positioning frame 2. The shape of the positioning groove 21 is the same as that of the sole, and it is mainly used to place the sole, and the positioning groove 21 can be used to initially position the sole. The positioning device 3 is arranged in the positioning frame 2 and is used to clamp and fix the sole; it includes a plurality of slidable positioning blocks 31 and a first cylinder 32 for driving the positioning blocks 31 to slide, so as to ensure the stability of the sole during the bonding process through the positioning blocks 31.

[0042] Preferably, four positioning blocks 31 are arranged along the circumference of the positioning groove 21, and correspondingly, four first cylinders 32 are arranged around the positioning frame 2, respectively. The telescopic shaft of the first cylinder 32 is connected to the side wall of the positioning block 31 away from the positioning groove 21, and the side wall of the positioning block 31 facing the positioning groove 21 is a curved surface, and fits with the curved surface of the corresponding side wall of the sole. After the sole brushed with glue is placed in the positioning groove 21, all the first cylinders 32 are started at the same time, and all the positioning blocks 31 are driven to approach the positioning groove 21, so as to clamp and fix the sole, and by setting the moving distance of all the first cylinders 32, the sole can be positioned to a preset position, thereby improving the accuracy when the sole and the upper are bonded. Preferably, in order to improve the convenience of operation, a sensing device can be set in the positioning frame 2, and when the sole is placed in the positioning groove 21, the sensing device controls the first cylinder 32 to start.

[0043] Reference Figure 1 and Figure 2 In an optional embodiment, a plurality of protrusions 22 may be provided on the inner bottom wall of the positioning groove 21 of the positioning frame 2. The protrusions 22 are provided corresponding to the depressions on the sole surface. When the upper is pressed downward, the protrusions 22 squeeze the depressions on the sole, thereby improving the bonding effect between the sole and the upper.

[0044] Reference Figure 1 and Figure 3 In this embodiment, the fixing device 4 includes a mounting seat 41, two clamping blocks 42 slidably arranged on both sides of the mounting seat 41, and a power member 43 for driving the two clamping blocks 42 to move closer to or farther from each other. Specifically, the clamping block 42 includes a first block 421 arranged along the vertical direction, and a second block 422 arranged along the horizontal direction. The first block 421 and the second block 422 form an "L" shape, and the second blocks 422 of the two clamping blocks 42 both extend toward the middle direction; correspondingly, the upper end of the shoe last arranged on the upper extends out of the upper, and the shoe last is provided with a slot for the second block 422 to be plugged in on both sides, so that when the two second blocks 422 are close to each other and plugged into the slot, the column shoe last can be fixed, thereby fixing the upper.

[0045] Reference Figure 3 and Figure 4, in this embodiment, the power member 43 can drive the two first blocks 421 to approach or move away from each other, thereby driving the second block 422 to slide. Specifically, the power member 43 includes a bidirectional screw 431, a worm gear 432, a worm 433, and a motor 434. Among them, the bidirectional screw 431 passes through the mounting seat 41 in the horizontal direction and is rotatably arranged on the driving seat by means of bearings or the like. The two ends of the bidirectional screw 431 have positive threads and reverse threads with opposite directions, and the two ends respectively pass through the two first blocks 421. At the same time, a guide rod 411 is also arranged on the mounting rod in the horizontal direction. The guide rod 411 is parallel to the bidirectional screw 431. The two ends of the guide rod 411 respectively pass through the mounting rod and slidably pass through the two first blocks 421. Thus, rotating the bidirectional screw 431 can drive the two first blocks 421 and the second block 422 to approach or move away from each other.

[0046] The worm gear 432 is sleeved on the side wall of the bidirectional screw 431, and is preferably arranged at the central position of the bidirectional screw 431. The worm 433 is rotatably arranged on the mounting seat 41. The motor 434 is also arranged on the mounting seat 41, and the worm gear 432 meshes with the worm 433. The output end of the motor 434 is connected to the worm 433. Starting the motor 434 can drive the worm 433 to rotate, and drive the bidirectional screw 431 to rotate through the transmission of the worm gear 432, thereby driving the two second blocks 422 to approach each other to clamp the shoe last. Preferably, in order to facilitate the positioning of the shoe upper, when the upper surface of the shoe last abuts against the lower surface of the mounting seat 41, the card slot on the shoe last and the second block 422 are located on the same horizontal plane. At the same time, chamfers are provided at the ends of the two second blocks 422 that approach each other. Thus, the long plate second block 422 is inserted into the card slot, and the shoe last and the shoe upper are positioned by the second block 422.

[0047] Refer to Figure 1 and Figure 3 , in this embodiment, the driving device 5 is a second cylinder 51. The second cylinder 51 is arranged on the machine table 1. The telescopic shaft of the second cylinder 51 extends vertically downward and is connected to the mounting seat 41. Thus, the mounting seat 41 can be conveniently driven to move up and down by the second cylinder 51. Further optionally, a contact head 6 and an adjusting screw 7 are also arranged on the mounting seat 41. Among them, the upper end of the adjusting screw 7 is fixedly connected to a handle, and the lower end is threadedly connected through the mounting seat 41 and is connected to the contact head 6. The lower surface of the contact head 6 is an arc surface. When the mounting seat 41 moves downward and drives the inclined surface to adhere to the sole, the contact head 6 can abut against the shoe upper and apply pressure to it, thereby improving the adhesion effect between the sole and the shoe upper.

[0048] Refer to Figure 1 and Figure 2, in an optional embodiment, the gluing machine further includes a heating lamp 8, which is arranged on the side wall of the positioning frame 2 and extends along the length direction of the positioning frame 2. When the shoe upper is pressed onto the sole, starting the heating lamp 8 can further cure the glue.

[0049] The implementation principle of the gluing machine for rubber shoe production in the embodiment of the present application is as follows: when gluing the sole and the shoe upper, first apply glue to the connection parts of the sole and the shoe upper respectively, then place the sole in the positioning groove 21 and start the first cylinder 32 to move the positioning block 31 to position the sole; then place the shoe last in the shoe upper under the mounting seat 41 and fix it through the clamping block 42, and then drive the shoe upper to move downward by the second cylinder 51 to press it tightly against the sole and maintain for a certain period of time. At this time, the first cylinder 32 can be started again to move the positioning block 31 a certain distance to squeeze the connection part on the side of the sole and the shoe upper; at the same time, after pressing the sole and the shoe upper tightly, the heating lamp 8 can be turned on to improve the gluing effect.

[0050] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
