A quick tool changing structure for front lasting machine

Abstract

The utility model discloses a quick blade changing structure of a sweeping knife of a front-end gang machine. When installing the sweeping knife, a part of the front end of the sweeping knife is extended into the accommodating space through the side opening of the accommodating space, and a first positioning piece is made to enter the first positioning hole to realize the detachable pivotal cooperation between the sweeping knife and the knife sleeve. Then, the sweeping knife is swung to make the second positioning piece swing to enter the second positioning hole, and the moving piece is driven to move to a position against the second positioning piece to lock the sweeping knife and the knife sleeve, thereby completing the assembly of the sweeping knife and the knife sleeve. When releasing the assembly, it is only necessary to move the moving piece to a position away from the second positioning piece, and then the sweeping knife can be taken out from the accommodating space after being swung to a certain amplitude. When the sweeping knife is taken out of the accommodating space, the first positioning hole is moved and separated from the first positioning piece. Compared with the traditional one, the utility model has a simple structure, is easy to operate, and has a fast blade changing speed, which effectively improves the production efficiency and reduces the production cost.

Description

Technical Field

[0001] The utility model relates to the technical field of shoemaking machinery, in particular to a quick knife-changing structure for a knife-wiping machine for a toe-lasting machine. Background Art

[0002] At present, in the process of shoemaking, the bonding of the upper and the sole needs to be completed by the fore-lasting machine. A layer of glue is applied to the periphery of the sole, and the upper is adhered to the sole under the pressure of the splint. Then, the pusher moves forward and backward to drive the splint to press forward, so that the upper and the sole fit better. However, the middle waist of the sole is not suitable for the pressure of the splint. Therefore, a pair of sweeping knives are set above the splint to press the middle waist part (i.e. the arch of the sole) to complete the fore-lasting operation.

[0003] The sweeping blade in the prior art is mainly locked on the execution end of the driving mechanism by a plurality of bolts, so that the driving mechanism can drive the sweeping blade to press the middle waist part. Since the sweeping blade occupies a large area, multiple bolts are required to lock it. However, the shoe shapes are diverse, resulting in different middle waist parts, and the corresponding sweeping blades are also different. Therefore, the sweeping blade needs to be replaced frequently. Although the bolt locking has a simple structure, the replacement time is long. It takes about 10-20 minutes to replace the sweeping blade each time. If the sweeping blade is replaced 3-4 times a day, the output will be reduced by 200-400 pairs of shoes, resulting in low production efficiency and increased production costs. Utility Model Content

[0004] The main purpose of the utility model is to provide a quick tool changing structure for a toe lasting machine sweeping knife, aiming to improve the tool changing efficiency of the toe lasting machine sweeping knife, improve production efficiency and reduce production costs.

[0005] To achieve the above-mentioned purpose, the utility model proposes a quick tool changing structure of a front-side ganging machine sweeping knife, comprising an upper clamping plate, a lower clamping plate and a driving mechanism, a pair of sweeping knives are mirror-imaged between the upper clamping plate and the lower clamping plate, the sweeping knives can press the product by the drive of the driving mechanism, a knife sleeve connected to the execution end of the driving mechanism is movably installed between the upper clamping plate and the lower clamping plate, the knife sleeve is formed with a accommodating space open on one side, a first positioning member is provided in the accommodating space, a second positioning member and a first positioning hole adapted to the first positioning member are respectively provided at the front end and the middle part of the sweeping knife, the sweeping knife is detachably pivoted with the knife sleeve through the cooperation of the first positioning hole and the first positioning member, the knife sleeve is also provided with a second positioning hole and a moving member, the sweeping knife can swing relative to the knife sleeve between a position where the second positioning member enters the second positioning hole and exits, the moving member is movably installed on the knife sleeve and can move between a position where it abuts against the second positioning member to lock the sweeping knife and the knife sleeve and a position away from the unlocking position.

[0006] The technical solution of the utility model is that a knife sleeve connected to the execution end of the driving mechanism is arranged between the upper clamping plate and the lower clamping plate, and the knife sleeve is installed with a sweeping knife, so that the driving mechanism can drive the knife sleeve to drive the sweeping knife to press the product, and a storage space with an opening on one side is arranged on the knife sleeve, and a first positioning member, a second positioning hole and a moving member are arranged in the storage space, and a first positioning hole and a second positioning member are arranged on the sweeping knife.

The sweeping knife is then swung to make the second positioning member swing into the second positioning hole, and the moving member is driven to move to a position against the second positioning member to lock the sweeping knife and the knife sleeve, thereby completing the assembly of the sweeping knife and the knife sleeve. When releasing the assembly, it is only necessary to move the moving member to a position away from the second positioning member, and then swing the sweeping knife to a certain amplitude and then take it out from the accommodating space. When the sweeping knife is taken out of the accommodating space, the first positioning hole is separated from the first positioning member.
