Technical Field

[0001] The utility model relates to the technical field of labor protection shoe production, in particular to a labor protection shoe manufacturing and pressing device. Background Art

[0002] Safety shoes are special protective footwear worn during dangerous operations. Depending on the working conditions, the soles of safety shoes need to meet various requirements such as heat insulation, insulation, anti-slip, and anti-puncture, so the soles of safety shoes are usually multi-layer composite structures;

[0003] At present, the connection between the layers of the structure is usually achieved by bonding with special glue. During the bonding process, external force needs to be applied to make the parts that have been glued and need to be bonded fit together. At this time, a press machine is needed to mechanically press the sole;

[0004] However, during the pressing process of the existing shoe pressing equipment, the glue at the bonding point will inevitably seep out from the side and flow onto the positioning device or the workbench. If not handled in time, it will not only affect the appearance of the shoes, but also affect the subsequent pressing process. Utility Model Content

[0005] In order to solve the problems existing in the prior art, the utility model provides a labor protection shoe manufacturing and pressing device, which can quickly remove the overflowed glue and improve the aesthetics of the labor protection shoe production.

Detailed Embodiment

[0030] For the convenience of those skilled in the art to understand, the following further explains the utility model with reference to the drawings.

[0031] As Figures 1-4A labor protection shoe manufacturing pressing device shown in the figure includes a workbench 1, on which a lifting mechanism 2 is installed, and a pressing plate 15 is installed on the lifting mechanism 2. A lifting table 18 for placing the shoe sole 12 is installed on the workbench 1. The lifting table 18 is located below the pressing plate 15. The pressing plate 15 is a profiling plate with the same shape and size as the shoe sole 12. The shape of the lifting table 18 is also the same as that of the shoe sole 12, but the cross-sectional area of the lifting table 18 is larger than that of the pressing plate 15 and the shoe sole 12.

[0032] Specifically, the lifting table 18 can play a role in positioning the placement of the shoe sole 12. When the shoe sole 12 is placed on the lifting table 18, the pressing plate 15 above it will be driven by the lifting mechanism 2 to move downward and press the shoe sole 12 tightly, so that its various layers can be bonded together more closely.

[0033] A positioning mechanism is installed on the workbench 1 of the present utility model. The positioning mechanism includes a limiting roller 14 and a translation component. The limiting roller 14 and the translation component are respectively installed on both sides of the lifting table 18. The translation component includes a connecting frame 5 parallel to the length direction of the lifting table 18. Rotating drums 3 are installed at both ends of the connecting frame 5. One side of the connecting frame 5 away from the lifting table 18 is connected with a cylinder 4. One end of the cylinder 4 away from the connecting frame 5 is fixed on the workbench 1. The cylinder 4 is perpendicular to the connecting frame 5, and the cylinder 4 can drive the translation component to translate along the width direction of the lifting table 18.

[0034] Specifically, a driving component is installed on the workbench 1. The driving component is located on the side of the lifting table 18 close to the limiting roller 14. A cleaning belt 7 is sleeved outside the lifting table 18. The height of the cleaning belt 7 is greater than the height of the shoe sole 12, and the side of the shoe sole 12 is completely wrapped, which is convenient for wiping off the overflow glue.

[0035] The cleaning belt 7 of the present utility model includes a chain rod conveyor belt 20. A wiping rubber cloth 19 is fixed inside the chain rod conveyor belt 20. The driving component includes a spur gear 13 that cooperates with the chain rod conveyor belt 20. A motor 16 is installed on the workbench 1. The motor 16 is connected to the spur gear 13. The teeth of the spur gear 13 can be inserted into the gap between two adjacent chain rods. The motor 16 drives the spur gear 13 to rotate, thereby pushing the chain rod conveyor belt 20 that cooperates with it to move.

[0036] Specifically, after the shoe sole is placed, the pressing plate 15 descends and abuts against the shoe sole. At the same time, the lifting table 18 descends until its upper end surface is flush with the workbench 1. During the descent of the lifting table 18, the cleaning belt 7 is smoothly sleeved outside the placed shoe sole 12. The translation component pushes the cleaning belt 7, so that the whole shoe sole moves towards the direction of the limiting roller 14 until the cleaning belt 7 contacts the limiting roller 14 and the driving component.

[0037] At this time, the driving component cooperates with the cleaning belt 7 to drive the cleaning belt 7 to rotate around the sole. A liquid sprayer capable of spraying glue remover is installed on the workbench 1. The liquid sprayer includes a columnar nozzle 8. A plurality of liquid outlet holes 17 are provided on the side wall of the columnar nozzle 8. The columnar nozzle 8 is rotatably installed on the workbench 1. The lower end of the columnar nozzle 8 is connected to a liquid storage tank and an air pump. The columnar nozzle 8 is in contact with the inner side of the cleaning belt 7. The columnar nozzle 8 sprays the glue remover on the wiping cloth 19. As the cleaning belt 7 rotates, the glue that seeps to the side during the pressing process of the sole 12 is wiped off, ensuring the aesthetics of the production of the sole 12. At the same time, it can also prevent the overflowing glue from flowing onto the workbench 1 or the positioning mechanism, affecting subsequent processing.

[0038] In the utility model, the lifting mechanism 2 is located at one end of the lifting table 18, and the liquid sprayer is located at the other end of the lifting table 18. An inclined chute 11 is provided on the workbench 1. The inclined chute 11 is located on the side of the lifting table 18 close to the limiting roller 14. One end of the inclined chute 11 close to the lifting table 18 is located between the lifting table 18 and the liquid sprayer. A rotating shaft 9 is slidably installed on the inclined chute 11. A tension spring 10 is connected between the other end of the inclined chute 11 and the rotating shaft 9;

[0039] Specifically, the rotating shaft 9 abuts against the outer side of the cleaning belt 7. When the cleaning belt 7 rotates, it sequentially passes through the translation component, the rotating shaft 9 and the liquid sprayer. The rotating shaft 9 connected to the tension spring 10 plays a role in tensioning the cleaning belt 7, so that the wiping cloth 19 on the inner side of the cleaning belt 7 can tightly wrap around the sole 12 or the outer side of the lifting table 18, and also keeps the outer link belt conveyor 20 in a tensioned state, which can better cooperate with the spur gear 13 for transmission. In addition, it can adapt to soles 12 of different sizes, improving the application range of the device.

[0040] In the utility model, retaining rings 6 in contact with the upper end surface of the cleaning belt 7 are provided on both the limiting roller 14 and the two rollers 3. The ring width of the retaining ring 6 is the same as the thickness of the cleaning belt 7. When the lifting table 18 rises, the retaining ring 6 can limit the upward movement of the cleaning belt 7. An arc chamfer 21 is provided at the turning point between the upper end surface and the side of the lifting table 18.

[0041] Specifically, after the pressing is completed, the lifting table 18 and the pressing plate 15 rise simultaneously. Since the lifting table 18 is larger than the sole 12, when the lifting table 18 rises, the air cylinder 4 contracts to drive the two rollers 3 away from the limiting roller 14, avoiding interference with the upper part of the lifting table 18. At the same time, the retaining rings 6 provided on the limiting roller 14 and the two rollers 3 can abut against the upper end surface of the cleaning belt 7, preventing the cleaning belt 7 from moving upward together with the lifting table 18. The arc chamfer 21 provided on the lifting table 18 plays a certain transitional role. Under the limitation of the retaining ring 6, the cleaning belt 7 can gradually disengage from the sole 12 and be sleeved on the larger lifting table 18 for the next pressing.

[0042] Specific working process

[0043] First step, place the sole 12 to be laminated on the lifting table 18, and place the entire sole 12 inside the area surrounded by the cleaning belt 7;

[0044] Second step, the lifting table 18 descends until its upper end face is flush with the workbench 1, and the cleaning belt 7 gradually slips onto the side of the sole 12 while the lifting table 18 is descending;

[0045] Third step, the air cylinder 4 extends to push the entire sole 12 towards the direction of the limiting roller 14 until the limiting roller 14, the spur gear 13, and the two rollers 3 all abut against the outside of the cleaning belt 7, realizing the automatic positioning of the sole 12;

[0046] Fourth step, the lifting structure drives the pressing plate 15 to move downward to press the sole 12

[0047] Fifth step, the motor 16 is turned on, the spur gear 13 drives the cleaning belt 7 to rotate around the sole 12, and the liquid sprayer is also turned on at the same time to spray the glue remover onto the wiping cloth 19 of the cleaning belt 7. As the cleaning belt 7 rotates, the glue overflowing during the lamination process is wiped off;

[0048] Sixth step, the lifting table 18 and the pressing plate 15 rise simultaneously, the air cylinder 4 drives the two rollers 3 to move in the reverse direction, and the laminated sole 12 is pushed out during the rising process of the lifting table 18, and the cleaning belt 7 also slips onto the lifting table 18 to complete the reset.
