Description

Technical Field

[0001] The utility model relates to an improved invention of a shoe-making device with uppers, in particular to an improved invention of a shoe-making device with uppers having both casting and spraying functions. Background Art

[0002] In my country's rapidly developing shoemaking industry, the casting process has been used for a long time and has the advantages of fast foaming and high output. However, it also has the disadvantages of low molding density of the soles produced and large molding dosage. If a release agent is used, the material consumption is relatively high. Due to limited conditions, spraying has become a popular shoemaking process in recent years. It has the advantages of delicate patterns and few surface bubbles, but low output and relatively complex process. The existing upper shoemaking equipment does not have the function of alternating casting and spraying. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a shoe-making device with uppers having both casting and spraying functions.

[0004] In order to solve the above technical problems, the utility model is implemented by adopting the following technical scheme: the upper shoe-making equipment with both casting and spraying functions includes a mixing chamber and a screw, the mixing chamber is provided with a cleaning liquid inlet, a plurality of multi-component polymer inlets and a spray gas inlet, the screw can be rotatably arranged in the mixing chamber, and the tail end of the screw is equipped with a rotating power source, characterized in that: the screw can also move axially in the mixing chamber, and is equipped with an axial driving structure, the corresponding screw is also provided with an axial locking structure, the front end of the mixing chamber is detachable and replaceable and is equipped with a spray nozzle or a casting nozzle; when the mixing chamber is equipped with a spray nozzle, the corresponding screw is axially locked; when the mixing chamber is equipped with a casting nozzle, the corresponding screw can move axially.

[0005] The axial locking structure includes a magnetic lock, which is installed on the machine base. The rotary power source is installed on a mounting plate, which can be slidably arranged on the machine base. The mounting plate is transmission-connected to the axial driving structure. The mounting plate is locked with the magnetic lock, and a lock hole is provided on the corresponding mounting plate.

[0006] The axial driving structure is a servo electric cylinder.

[0007] A guide rail and a sliding block that are slidably matched are arranged between the mounting plate and the machine base.

[0008] The spray nozzle is provided with a gas restriction hole, which is communicated with the spray gas inlet.

[0009] The shoe-making equipment is installed on a robot.

[0010] The front end of the mixing chamber is also detachably and replaceably provided with an injection nozzle.

[0011] On the corresponding side molds, there are left and right feeding guide blocks that cooperate with each other. The front end of the feeding guide block is provided with an upper inclined surface, and there are two feeding ports on the upper inclined surface, which respectively conduct the outsole forming cavity and the midsole forming cavity.

[0012] The beneficial effect of the present utility model is that the improved integral shoe-making equipment with both pouring and spraying functions can switch between using the pouring and spraying functions. When using the spraying function, it is only turned on in the processes with high surface forming requirements such as the outsole, and cleaning is carried out by the mutual cooperation of the cleaning liquid and the high-pressure air source. At this time, the screw is axially locked; while in the pouring process, pouring is carried out in the mold cavity after spraying to quickly form the shoe sole. Cleaning is carried out by the axial movement of the screw rotating at high speed in the mixing chamber, and physical cleaning of the screw and the inner wall of the through hole is carried out by dry friction without using the cleaning liquid, saving material consumption. The switching between the two functions of pouring and spraying can be controlled and operated on the human-machine interface. BRIEF DESCRIPTION OF THE DRAWINGS

In this embodiment, refer to the attached Figures 1-6The uppered shoe-making equipment with both casting and spraying functions includes a mixing chamber 11 and a screw 8. The mixing chamber 11 is provided with a cleaning liquid inlet 14, a plurality of multi-component polymer inlets 15 and a spray gas inlet 16. The plurality of multi-component polymer inlets 15 are equipped with a needle valve 10. The screw 8 is rotatably arranged in the mixing chamber 11, and a rotary power source 7 is arranged at the rear end of the screw 8. The rotary power source 7 is preferably an electric spindle. The screw 8 can also move axially in the mixing chamber 11 and is equipped with an axial driving structure. The corresponding screw 8 is also provided with an axial locking structure. The front end of the mixing chamber 11 is detachably and replaceably equipped with a spray nozzle 13 or a pouring nozzle 12. Specifically, the spray nozzle 13 and the pouring nozzle 12 have a shoulder step and are connected to the mixing chamber 11 by a bolt 9; when the mixing chamber 11 is equipped with the spray nozzle 13, the corresponding screw 8 is axially locked; when the mixing chamber 11 is equipped with the pouring nozzle 12, the corresponding screw 8 can move axially.

[0021] As a further improved specific implementation method, the axial locking structure includes a magnetic lock 4, which is installed on the machine base 6.

The mounting plate 2 is locked with the magnetic lock 4. A locking hole is provided on the corresponding mounting plate 2. When the mounting plate 2 is driven to the desired position by the axial drive structure, the magnetic lock 4 is energized for locking.

[0022] As a further improved specific implementation, the axial drive structure is a servo electric cylinder 1 with controllable power and high precision.

[0023] As a further improved specific implementation, a gas restriction hole is provided on the spray nozzle 13, and the gas restriction hole is communicated with the spray gas inlet 16, and the spray gas inlet 16 is connected to the gas source.

[0024] As a further improved specific implementation, the shoe-making equipment is installed on a robot 17, and the robot 17 is a multi-axis robot to achieve the transfer between the spraying and pouring stations.

[0025] As a further improved specific implementation method, the front end of the mixing chamber 11 can be removably and replaceably equipped with an injection nozzle, and the injection process is used to replace the pouring process and cooperate with the spraying process. The principle is the same as the cooperation between the pouring process and the spraying process, or the injection process is used alone, and the sole formed by the injection process has the advantage of high density.

[0026] See attached Figure 6, in order to adapt to the combination of the injection process and the robot, corresponding left and right injection guide blocks are provided on the corresponding side mold 18. The left and right injection guide blocks are respectively arranged on the left and right side molds, and a complete injection guide block 19 is formed when the mold is closed. The front end of the injection guide block 19 is provided with an upper inclined surface, and two injection ports 20 are arranged on the upper inclined surface, which respectively conduct the outsole forming cavity and the midsole forming cavity. The outsole can be formed by spraying, and the midsole is formed by injection molding, or both the outsole and the midsole are formed by injection molding.

[0027] The operation sequence of the present utility model:

[0028] Step 1: As Figure 1 The servo cylinder 1 drives the mounting plate 2 and the rotary power source 7 to move forward, driving the screw rod 8 forward and entering the inside of the mixing chamber 11. The magnetic lock 4 is energized to lock the mounting plate 2 so that it cannot move axially;

[0029] Step 2: After the rotary power source 7 is started, the screw rod 8 rotates at a high speed. The cleaning liquid inlet 14 is connected to a high-pressure air source to blow air into the gap between the screw rod 8 and the through hole, removing the easily detachable multi-component polymer residues attached to the inner wall of the screw rod 8 and the through hole, and discharging them through the nozzle;

[0030] Step 3: The robot 17 moves to the spraying position of the work station, and the needle valve 10 is opened at the same time. The multi-component polymer A and B stock solutions are ejected for the spraying process of the sole. The spraying position is mainly the outsole, where the pattern is relatively dense, or other parts with few bubbles, beautiful patterns, and high process requirements;

[0031] Step 4: The robot 17 retreats to the initial position. The cleaning liquid inlet 14 injects a chemical cleaning solvent to clean the gap between the screw rod 8 and the through hole, removing the multi-component polymer residues that are difficult to detach from the inner wall of the screw rod 8 and the through hole, and discharging them through the spraying nozzle 13; then the cleaning liquid inlet 14 is connected to the high-pressure air source again to blow air into the gap between the screw rod 8 and the through hole, thoroughly removing the residual chemical cleaning solvent, multi-component polymer and its reaction products, and discharging them through the spraying nozzle 13;

[0032] Step 5: The robot 17 installs the pouring nozzle 12 by setting and quickly disassembling the spraying nozzle 13;

[0033] Step 6: The work station enters the next process, such as Figure 2 , the robot 17 moves to the pouring position of the next work station, the magnetic lock 4 is powered off, and the needle valve 10 is opened at the same time. The multi-component polymer A and B stock solutions are ejected to pour the sprayed mold cavity, and after foaming, the sole is formed;

[0034] Step 7: After completion, such as Figure 3, the rotary power source 7 drives the screw 8 to rotate at a high speed. At the same time, the servo electric cylinder 1 drives the screw 8 to advance to a position flush with the outer end face of the pouring nozzle. The screw 8 moves axially back and forth, and uses dry friction to physically clean the inner wall of the screw 8 and the through hole. This section is the cleaning process, and the cleaning time of the inner wall is set through the human-machine interface;

[0035] Thus, the production of one shoe is completed. Then, the robot 17 disassembles the pouring nozzle 12 and installs the spraying nozzle 13. Then, repeat the above steps to produce the next shoe.

[0036] In summary, the above is only the preferred embodiment of the present invention and is not used to limit the protection scope of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
