Description

Technical Field

[0001] The utility model belongs to the technical field of shoe last processing, and particularly relates to a limiting and supporting structure for shoe last processing. Background Art

[0002] As a forming mold of shoes, the shoe last not only determines the shape and style of the shoes, but also determines whether the shoes fit well and can play a role in protecting the feet. The shoe last is usually made by injection molding, and there are injection plastic heads at the head and tail of the last. Subsequently, the injection plastic heads at the head and tail of the shoe last surface need to be cut and trimmed. When cutting and trimming the injection plastic heads at the head and tail of the shoe last surface, the shoe last needs to be installed on the fixture of the processing limiting and supporting structure. When the traditional fixture of the shoe last processing limiting and supporting structure is used, the staff needs to install and remove the shoe last repeatedly, with a large labor intensity, and the cutting and processing speed of the shoe last is relatively slow. Therefore, a new type of shoe last processing limiting and supporting structure is designed to change the above technical defects. Summary of the Utility Model

[0003] (1) Technical Problems to be Solved

[0004] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a limiting and supporting structure for shoe last processing, which aims to solve the technical problems that when the fixture of the existing shoe last processing limiting and supporting structure is used, the staff needs to install and remove the shoe last repeatedly, with a large labor intensity, and the cutting and processing speed of the shoe last is relatively slow.

[0005] (2) Technical Solutions

[0006] To solve the above technical problems, the utility model provides such a limiting and supporting structure for shoe last processing. The limiting and supporting structure includes a chain plate conveyor. A shoe last fixing shell is fixedly installed on the outer surface of each chain plate of the chain plate conveyor through a support plate, and a positioning rod is fixedly connected to the outer surface of each chain plate. A shoe last body is installed inside the shoe last fixing shell, and a last head and a last tail are arranged on the outer surface of the shoe last body. Through holes are arranged on the outer surface of the shoe last body, and the top end of the positioning rod is slidably installed inside the through holes. A pressing plate is fixedly installed on the outer surface of the chain plate conveyor through a positioning plate, and the bottom surface of the shoe last body is in contact with the bottom surface of the pressing plate. A last head cutter and a last tail cutter are arranged outside the chain plate conveyor. A last tail fixing shell is installed on the outer surface of the chain plate conveyor through a first support column, and a last head fixing shell is installed on the outer surface of the chain plate conveyor through a second support column.

[0007] When using the limit support structure of this technical solution, the chain conveyor intermittently operates and advances by using a stepping motor to send pulses through a controller. When the shoe last body is being cut, the chain conveyor is in an intermittent pause state. The operator holds the shoe last body and inserts the toe and heel of the last into the toe fixing shell and heel fixing shell respectively and presses downwards. The shoe last body falls into the shoe last fixing shell. The top of the positioning rod is inserted into the through hole on the surface of the shoe last body for positioning. Then the chain conveyor intermittently pauses and advances in contact. The chain conveyor drives the shoe last fixing shell, support plate and positioning rod on its surface forward, thereby driving the shoe last body installed by the operator forward to the lower part of the pressing plate. The toe and heel of the shoe last body are respectively pulled out from the toe fixing shell and heel fixing shell. Under the action of the pressing plate, the top of the shoe last body is pressed and fixed. As the chain conveyor intermittently advances and drives the shoe last body closer to the heel cutter and toe cutter, the heel cutter and the shoe last body automatically cut the toe and heel. When the cut shoe last body advances with the chain conveyor and disengages from the pressing plate, it advances with the chain conveyor, drives the shoe last fixing shell and the positioning rod downward, and the shoe last body automatically drops, realizing semi-automatic cutting and automatic discharging of the shoe last body, increasing the cutting speed of the shoe last body, and reducing the labor intensity of the operator.

[0008] Preferably, horn rings are fixedly connected to the tops of both the heel fixing shell and the toe fixing shell. Through the setting of the horn rings, it is convenient for the toe and heel of the shoe last body to be inserted into the heel fixing shell and toe fixing shell for installation.

[0009] Furthermore, the end of the positioning rod away from the chain of the chain conveyor is conical. Through the setting of the conical positioning rod, it is convenient for the positioning rod to be inserted into the through hole on the surface of the shoe last body for installation and fixation.

[0010] Even further, arc-shaped strips are fixedly connected to the outer surface of the pressing plate. Through the setting of the arc-shaped strips, it is convenient for the shoe last body to enter under the pressing plate for fixation, preventing the shoe last body from touching the pressing plate and causing jamming or damage.

[0011] Even further, a material box is arranged below the chain conveyor, and rollers are installed on the bottom surface of the material box. Through the setting of the rollers and the material box, it is convenient to collect the cut shoe last bodies dropped by the chain conveyor, and the material box can be moved out and its interior can be cleaned.

[0012] (3) Beneficial effects

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] The chain plate conveyor of the utility model uses a stepping motor to send pulses through a controller to make it run intermittently forward. When the shoe last body is being cut, the chain plate conveyor is in an intermittent pause state. The worker holds the shoe last body and inserts the toe and heel ends into the toe fixing shell and the heel fixing shell respectively and presses down. The shoe last body falls into the shoe last fixing shell. The top of the positioning rod is inserted into the through hole on the surface of the shoe last body for positioning. Then the chain plate conveyor advances intermittently in contact. The chain plate conveyor drives the shoe last fixing shell, the support plate and the positioning rod on its surface forward, and then drives the shoe last body installed by the worker forward to the lower part of the pressing plate. The toe and heel ends on the surface of the shoe last body are respectively pulled out from the toe fixing shell and the heel fixing shell, and the top of the shoe last body is pressed and fixed under the action of the pressing plate. As the chain plate conveyor advances intermittently with the shoe last body approaching the heel cutter and the toe cutter, the heel cutter and the shoe last body automatically cut the toe and heel ends. When the cut shoe last body advances with the chain plate conveyor and separates from the pressing plate, it advances with the chain plate conveyor, drives the shoe last fixing shell and the positioning rod downward, and the shoe last body automatically falls off, realizing the semi-automatic cutting and automatic discharging of the shoe last body, increasing the cutting speed of the shoe last body and reducing the labor intensity of the worker.

[0021] This detailed embodiment is a limit support structure for shoe last processing, and its structural schematic diagram is asFigures 1-5 As shown in the figure, the limit support structure includes a chain plate conveyor 1. On the outer surface of each chain plate of the chain plate conveyor 1, a shoe last fixing shell 17 is fixedly installed through a support plate 18, and a positioning rod 19 is fixedly connected to the outer surface of each chain plate. A shoe last body 11 is installed inside the shoe last fixing shell 17, and a last head 12 and a last tail 13 are arranged on the outer surface of the shoe last body 11. A through hole 20 is arranged on the outer surface of the shoe last body 11, and the top end of the positioning rod 19 is slidably installed inside the through hole 20. A pressing plate 4 is fixedly installed on the outer surface of the chain plate conveyor 1 through a positioning plate 5, and the bottom surface of the shoe last body 11 is in contact with the bottom surface of the pressing plate 4. A last head cutter 10 and a last tail cutter 8 are arranged outside the chain plate conveyor 1. A last tail fixing shell 3 is installed on the outer surface of the chain plate conveyor 1 through a first support column 2, and a last head fixing shell 15 is installed on the outer surface of the chain plate conveyor 1 through a second support column 16.

[0022] Among them, horn rings 14 are fixedly connected to the top ends of the last tail fixing shell 3 and the last head fixing shell 15. Through the arrangement of the horn rings 14, it is convenient for the last head 12 and the last tail 13 of the shoe last body 11 to be inserted into the last tail fixing shell 3 and the last head fixing shell 15 for installation. One end of the positioning rod 19 away from the chain plate of the chain plate conveyor 1 is conical. Through the arrangement of the conical positioning rod 19, it is convenient for the positioning rod 19 to be inserted into the through hole 20 on the surface of the shoe last body 11 for installation and fixation. An arc-shaped strip 9 is fixedly connected to the outer surface of the pressing plate 4. Through the arrangement of the arc-shaped strip 9, it is convenient for the shoe last body 11 to enter below the pressing plate 4 for fixation, preventing the shoe last body 11 from touching the pressing plate 4 and causing jamming or damage.

[0023] In addition, a material box 7 is arranged below the chain plate conveyor 1, and rollers 6 are installed on the bottom surface of the material box 7. Through the arrangement of the rollers 6 and the material box 7, it is convenient to collect the shoe last body 11 that has been cut and dropped by the chain plate conveyor 1, and the material box 7 can be moved out and its interior can be cleaned.

[0024] Working principle: When using the limit support structure of this technical solution, the chain plate conveyor 1 intermittently operates and advances by using a stepping motor to send pulses through a controller. When the shoe last body 11 is being cut, the chain plate conveyor 1 is in an intermittent pause state. The operator holds the shoe last body 11 and inserts the toe 12 and the heel 13 into the toe fixing shell 15 and the heel fixing shell 3 respectively and presses downwards. The shoe last body 11 falls into the shoe last fixing shell 17. The top end of the positioning rod 19 is inserted into the through hole 20 on the surface of the shoe last body 11 for positioning. Then the chain plate conveyor 1 intermittently pauses and advances in contact. The chain plate conveyor 1 drives the shoe last fixing shell 17, the support plate 18 and the positioning rod 19 on its surface to advance, thereby driving the shoe last body 11 installed by the operator to advance under the pressing plate 4. The toe 12 and the heel 13 on the surface of the shoe last body 11 are respectively pulled out from the toe fixing shell 15 and the heel fixing shell 3. Under the action of the pressing plate 4, the top end of the shoe last body 11 is pressed and fixed. As the chain plate conveyor 1 intermittently advances and drives the shoe last body 11 closer to the heel cutter 8 and the toe cutter 10, the heel cutter 8 and the shoe last body 11 automatically cut the toe 12 and the heel 13. When the shoe last body 11 after cutting advances with the chain plate conveyor 1 and disengages from the pressing plate 4, it advances with the chain plate conveyor 1, drives the shoe last fixing shell 17 and the positioning rod 19 downwards, and the shoe last body 11 automatically drops, realizing the semi-automatic cutting and automatic discharging of the shoe last body 11, increasing the cutting speed of the shoe last body 11 and reducing the labor intensity of the operator.

[0025] All technical features in this embodiment can be freely combined according to actual needs.

[0026] The above embodiment is a preferred implementation solution of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of this technical solution is within the protection scope of the present invention.
