Abstract
Description
Technical Field
[0001] The present invention relates to the field of shoemaking machinery, and in particular to a driving device for a side pressing group of a sole pressing machine and a sole pressing machine, and specifically to a driving device for a side pressing group of a sole pressing machine that is driven by hydraulic oil to achieve rapid start-up. Background Art
[0002] In the process of shoemaking, a sole pressing machine is usually used to glue the sole to the upper. For example, the sole pressing machine disclosed in Taiwan Invention Patent No. M557534 needs to first drive the side pressing groups on the left and right sides to clamp the sides of the sole relatively before gluing the upper. The conventional side pressing group is provided with a plurality of hydraulic rods, which are arranged along the sides of the sole, and a pressure block is provided at the front end of each hydraulic rod.
[0003] The hydraulic rod of the conventional sole pressing machine is mainly moved by the thrust generated by the pressurized hydraulic oil. The driving end of each hydraulic rod is correspondingly inserted into an hydraulic chamber, and a spring is connected between the driving end and the hydraulic chamber. The hydraulic chamber is connected to the oil tank by an oil pipe, and the outside of the oil tank is connected to a pressurizing device. When in use, it is necessary to start the pressurizing machine to pressurize the inside of the oil tank to reach the preset pressure value. The hydraulic oil in the oil tank flows to each hydraulic chamber through the oil pipe under the action of pressure, and generates thrust on the driving end of each hydraulic rod. Each hydraulic rod moves in the thrust direction and compresses the spring, so that the pressurizing block presses against the side of the sole to clamp the sole. At this time, the pressurizing device needs to continue to operate to maintain the internal pressure of the oil tank, so that each hydraulic rod is maintained in a clamping state. After the shoe upper is adhered, the pressurizing machine stops operating, the pressure in the oil tank decreases, the hydraulic oil flows back to the oil tank along the oil pipe, and the hydraulic rod drives each pressurizing block to reset under the elastic restoring force of the spring.
[0004] However, after each operation is completed and the next processing is carried out, it is necessary to wait for the pressurizing device to re-pressurize the oil tank to the set value before the sole can be placed, which prolongs the processing time. In addition, the pressurizing device needs to continue to pressurize during operation, which consumes a lot of energy. The oil supply route is complicated, but it can only drive the hydraulic rod to move and extend in one direction, and cannot assist in resetting. Therefore, a spring is required between the driving end of each hydraulic cylinder and the hydraulic chamber to assist in resetting, resulting in a large number of assembly parts for the device, which is not in line with production costs and is not convenient for daily maintenance.
[0005] Therefore, it is necessary to develop a new technical solution to solve the above problems. Summary of the invention
[0006] In view of this, the present invention aims at the deficiencies in the prior art, and its main purpose is to provide a driving device for the side pressing group of a bottom pressing machine and a bottom pressing machine, which can control the side pressing block of the side pressing group to extend, clamp and reset by an oil circuit, so as to achieve precise pressurization, and does not require continuous pressurization to reduce energy consumption; The second main purpose is to provide a driving device of the side pressing group of the sole pressing machine and the sole pressing machine, wherein the driving group drives the hydraulic cylinder to pressurize the driving oil circuit so that each side pressing block extends and pushes against the sole, and then pressurizes the reset oil circuit so that each side pressing block is reset. The oil circuit design is simple and easy to maintain; Another object is to provide a driving device for a side pressing group of a bottom pressing machine and a bottom pressing machine, which can control the stroke of the piston rod of the hydraulic cylinder group driven by the driving group to accurately control the pressure applied to the driving oil circuit and the reset oil circuit; Another purpose is to provide a driving device and a bottom pressing machine for the side pressing group of a bottom pressing machine, which seal the hydraulic oil in the driving oil circuit and the reset oil circuit respectively, without the need for additional pressurization to transport the hydraulic oil to the oil circuit, thereby shortening the startup time and reducing energy consumption.
[0007] To achieve the above purpose, the present invention adopts the following technical solutions: A driving device for a side pressing group of a sole pressing machine comprises: A driving group, comprising a power motor, wherein the driving end of the power motor is connected to a guide rod; A hydraulic cylinder group, comprising a cylinder body capable of containing hydraulic oil and a piston rod, wherein one end of the cylinder body is provided with a first interface, and the other end of the cylinder body is provided with a second interface for the hydraulic oil to flow out and return; one end of the piston rod is located in the cylinder body, and the other end of the piston rod passes through the cylinder body and is connected to the guide rod by a guide block, so as to drive the piston rod to reciprocate along the axial direction of the cylinder body; Two side pressure groups are symmetrically arranged on both sides of a storage platform, each of the side pressure groups has a plurality of side pressure blocks, each of the side pressure groups is connected to the first interface by a driving oil circuit, and is connected to the second interface by a reset oil circuit, and the driving oil circuit and the reset oil circuit are respectively connected to each side pressure block, and the driving oil circuit and the reset oil circuit are both filled with hydraulic oil; When the power motor drives the guide rod to drive the piston rod to move toward the first interface direction, the hydraulic oil in the driving oil circuit is pushed to generate pressure, thereby driving each side pressure block to move and extend, and at the same time the hydraulic oil in the reset oil circuit flows back into the cylinder body; when the power motor drives the guide rod to drive the piston rod to move toward the second interface direction, the hydraulic oil in the reset oil circuit is pushed to generate pressure, thereby pushing each side pressure block back and resetting, and the hydraulic oil in the driving oil circuit flows back into the cylinder body through the first interface, and the driving oil circuit or the reset oil circuit is pressurized through the reciprocating movement of the piston rod to drive the side pressure blocks to telescope and move.
[0008] As a preferred solution, the power motor is a servo motor.
[0009] As a preferred solution, the guide rod is a screw rod.
[0010] As a preferred solution, one end of the guide block is provided with a screw hole for being screwed to the guide rod, and the other end thereof is fixedly connected to the piston rod.
[0011] As a preferred solution, a fixing seat is provided at one end of the cylinder body adjacent to the piston rod for assembling the driving group, and a passage connecting the second interface and the interior of the cylinder body is provided in the fixing seat.
[0012] As a preferred solution, a reducer is connected between the driving end of the power motor and the guide rod, and the power motor drives the guide rod to rotate through the reducer.
[0013] A sole pressing machine, which is applied with a driving device of the side pressing group of the sole pressing machine as described in any of the above items.
[0014] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical scheme that it is mainly through the arrangement of a driving group, a hydraulic cylinder group, and two side pressure groups. The driving oil circuit and the return oil circuit are filled with hydraulic oil, and the hydraulic cylinder group is used as the pressurization source and hydraulic oil accommodating space of the driving oil circuit and the return oil circuit. The movement of the piston rod can pressurize one of the oil circuits and release the pressure of the other oil circuit, and then the pressurized oil circuit actuates each side pressure block, and there is no need to wait for the completion of the oil tank pressurization before delivering the hydraulic oil, thus shortening the starting time. A guide block is screwed to a screw rod and the guide block drives the piston rod to move, so that the position of the piston rod can be positioned to maintain the required pressure of each oil circuit. There is no need to continuously operate the driving group, and it can be used immediately after it is turned on, which significantly reduces energy consumption. Secondly, the servo motor is used to control the rotation speed of the screw through the reducer, so as to accurately control the movement position of the piston rod, so as to adjust the pressure applied to the driving oil circuit and the reset oil circuit, so as to achieve precise pressure application to adapt to clamping soles of different sizes; Furthermore, by moving the piston rod and pressurizing the driving oil circuit, the side pressure blocks can be driven to extend and press the sole, and then the side pressure blocks can be pushed back and reset by moving the pressurizing reset oil circuit in the reverse direction. The extension and retraction of the side pressure blocks can be controlled without adding additional components. Furthermore, the driving oil circuit and the reset oil circuit respectively drive the side pressure blocks to extend for clamping and push back for reset, without the need for additional reset components. The structure is simple, the difficulty of equipment processing is reduced, and daily maintenance is convenient.

DETAILED DESCRIPTION
[0018] Please refer to Figures 1 to 4 As shown, it shows the specific structure of an embodiment of the present invention.
[0019] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "up", "down", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0020] As shown in FIG. 1 to FIG. 2 , a driving device for the side pressing group of a bottom pressing machine includes a driving group 1 , a hydraulic cylinder group 2 and two side pressing groups 3 .
[0021] The driving group 1 has a power motor 11, and the driving end of the power motor 11 is connected to a guide rod 12. The present invention preferably uses a servo motor to control the rotation speed of the guide rod 12, and the guide rod 12 is preferably a screw.
[0022] The hydraulic cylinder group 2 has a cylinder body 21 that can accommodate hydraulic oil and a piston rod 22. One end of the cylinder body 21 is provided with a first interface 211, and the other end of the cylinder body 21 is provided with a second interface 212, so that the hydraulic oil can flow out and return. One end of the piston rod 22 is located in the cylinder body 21, and the other end thereof passes through the cylinder body 21 and is connected to the guide rod 12 through a guide block 23. Among them, one end of the guide block 23 is provided with a screw hole (not shown in the figure) for being screwed to the guide rod 12, and the other end thereof is fixedly connected to the piston rod 22. The power motor 11 drives the guide rod 12 to rotate, and the guide block 23 drives the piston rod 22 to reciprocate along the axial direction of the cylinder body 21.
[0023] In order to prevent the guide rod 12 from rotating too fast, a reducer 13 is connected between the driving end of the power motor 11 and the guide rod 12. The power motor 11 drives the guide rod 12 to rotate through the reducer 13 to reduce the rotation rate of the guide rod 12, which is conducive to accurately controlling the displacement stroke of the piston rod 22 and achieving precise pressurization.
[0024] The cylinder body 21 is provided with a fixing seat 24 at one end adjacent to the piston rod 22, and the reducer 13 and the power motor 11 are sequentially assembled on one side thereof, and the driving end of the reducer 13 passes through the fixing seat 24 and is connected to the guide rod 12 to prevent the guide rod 12 from rotating due to the shaking of the power motor 11 when rotating, thereby ensuring smooth displacement of the piston rod 22. As shown in FIG. 3, a channel 241 is provided in the fixing seat 24 to connect the second interface 212 and the inside of the cylinder body 21, so that the hydraulic oil can be output from the cylinder body 21 or flow back to the cylinder body 21.
[0025] The two side pressure groups 3 are symmetrically arranged on both sides of a storage platform 4, and each of the side pressure groups 3 has a plurality of side pressure blocks 31. Each of the side pressure groups 3 is connected to the first interface 211 by a driving oil circuit 5, and is connected to the second interface 212 by a reset oil circuit 6. The driving oil circuit 5 and the reset oil circuit 6 are respectively connected to each side pressure block 31. It is particularly noted that the driving oil circuit 5 and the reset oil circuit 6 are both filled with hydraulic oil. The driving oil circuit 5 can drive each side pressure block 31 to move out toward the storage platform 4 to position the sole, and the reset oil circuit 6 pushes each side pressure block 31 back to reset and release the positioning.
[0026] In actual use, as shown in FIG. 3 and in combination with the numbering instructions of FIG. 1 and FIG. 2, the power motor 11 and the reducer 13 are started synchronously, and when the reducer 13 drives the guide rod 12 to drive the piston rod 22 to move toward the first interface 211, the hydraulic oil in the driving oil circuit 5 is pushed and flows to the driving end of each side pressure block 31 respectively, thereby pushing each side pressure block 31 to move and extend toward the storage table 4. At the same time, the hydraulic oil in the reset oil circuit 6 flows back to the cylinder body 21 through the second interface 212 to avoid the hydraulic oil in the reset oil circuit 6 increasing the resistance to the movement of each side pressure block 31, ensuring that each side pressure block 31 can be moved into place. Since the guide block 23 connected to the piston rod 22 is screwed to the guide rod 12, the relative position of the piston rod 22 and the guide rod 12 can be positioned. Therefore, after each side pressure block 31 reaches the clamping position, the power motor 11 and the reducer 13 can stop operating.
[0027] After the upper is bonded, as shown in FIG. 4 and in conjunction with the reference numerals in FIG. 1 and FIG. 2, the power motor 11 and the reducer 13 are started again to drive the guide rod 12 to drive the piston rod 22 to move toward the second interface 212, and the pressurization of the drive oil circuit 5 is released. As the piston rod 22 moves, the hydraulic oil in the cylinder body 21 is pushed into the reset oil circuit 6 toward the second interface 212, and the hydraulic oil in the drive oil circuit 5 flows back into the cylinder body 21 through the first interface 211. The hydraulic oil in the reset oil circuit 6 is pushed to generate pressure, which acts on each side pressure block 31 to push it back and reset it, thereby releasing the positioning of the sole.
[0028] Also, a sole pressing machine is provided, which is applied with a driving device of the side pressing group of the sole pressing machine as described in any of the above items.
[0029] The key point of the design of the present invention is that it mainly adopts the arrangement of a driving group, a hydraulic cylinder group and two side pressure groups, fills the driving oil circuit and the return oil circuit with hydraulic oil, and uses the hydraulic cylinder group as the pressurization source and hydraulic oil storage space of the driving oil circuit and the return oil circuit. The movement of the piston rod can pressurize one of the oil circuits and release the pressure of the other oil circuit, and then the pressurized oil circuit actuates each side pressure block, and there is no need to wait for the completion of the oil tank pressurization before delivering the hydraulic oil, thus shortening the starting time, and a guide block is screwed to a screw rod and driven by the guide block to move the piston rod, so that the position of the piston rod can be positioned to maintain the required pressure of each oil circuit, and there is no need to continuously operate the driving group, so it can be used immediately after it is turned on, and the energy consumption is significantly reduced; Secondly, the servo motor is used to control the rotation speed of the screw through the reducer, so as to accurately control the movement position of the piston rod, so as to adjust the pressure applied to the driving oil circuit and the reset oil circuit, so as to achieve precise pressure application to adapt to clamping soles of different sizes; Furthermore, by moving the piston rod and pressurizing the driving oil circuit, the side pressure blocks can be driven to extend and press the sole, and then the side pressure blocks can be pushed back and reset by moving the pressurizing reset oil circuit in the reverse direction. The extension and retraction of the side pressure blocks can be controlled without adding additional components. Furthermore, the driving oil circuit and the reset oil circuit respectively drive the side pressure blocks to extend for clamping and push back for reset, without the need for additional reset components. The structure is simple, the difficulty of equipment processing is reduced, and daily maintenance is convenient.
[0030] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
