Description

Technical Field

[0001] This utility model relates to the field of shoe upper making machine technology, and in particular to a shoe upper making machine. Background Technology

[0002] The mid-to-rear lasting machine is a commonly used production machine in automated shoe production. It is primarily used to form the mid-to-rear upper and midsole of the shoe last after the fore-toe part of the shoe has been formed by the fore-toe lasting machine. During operation, the fore-toe lasted upper, along with the shoe last and midsole, is placed on a last support column within the machine. The last support column is pulled forward by an oil rod, while simultaneously being pushed up by a support rod. As the shoe last rises, it is pressed down by a control rod on the mid-to-rear lasting machine, triggering a positioning switch to stop the shoe last from rising. Then, the mid-toe lasting tensioner and the rear lasting mechanism of the mid-to-rear lasting machine press against the upper, causing it to adhere to the midsole, achieving the desired mid-to-rear lasting effect.

[0003] For example, the authorization announcement number "CN217161230U" is named an improved shoe upper making machine. Compared with conventional shoe upper making machines, it can simultaneously complete the processing of the shoe upper and the material change of the upper, saving loading and unloading time and improving processing efficiency.

[0004] The above-mentioned and existing technologies have the following defects: the pressing column of the back lasting machine makes hard contact with the shoe upper when it comes into contact with the shoe upper, which can easily cause damage to the shoe upper; the eccentric hydraulic rod of the back lasting machine cannot move left and right, which makes the back lasting machine inflexible in operation; when the mounting plate of the back lasting machine rotates, it is supported by the column, which will cause the mounting plate to be unstable when rotating. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a shoe upper manufacturing machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a shoe upper making machine, including a worktable, movable support legs, and a vertical plate. A column is located in the center of the upper surface of the worktable. An installation groove is formed on the upper surface of the column. A first motor is located on the lower inner wall of the installation groove. An installation plate is located at the output end of the first motor. Support columns are located on both sides of the column on the upper surface of the worktable. A first annular groove and a second annular groove are formed on the lower surface of the installation plate. Rotating devices are located between the upper surface of the column and the inner wall of the first annular groove on both sides of the installation groove. Rotating devices are also located between the upper ends of the two support columns and the inner wall of the second annular groove. Multiple clamping blocks are evenly arranged in a ring on the upper surface of the worktable. Shoe upper molds are inserted into the upper surfaces of the multiple clamping blocks. Shoe uppers are detachably clamped onto the upper surfaces of the multiple shoe upper molds. A horizontal plate is fixedly connected to the upper left side of the vertical plate. A processing device is located on the lower surface of the horizontal plate.

[0008] Preferably, the processing device includes a first electric push rod, which is positioned directly above the heel counter of the rightmost shoe upper. A synchronization plate is fixedly connected to the lower end of the first electric push rod. An upper block is provided on the left side of the upper surface of the synchronization plate, and a second electric push rod is provided on the right side of the upper block. A groove is formed on the surface of the synchronization plate, and a slide rod is slidably connected inside the groove. A push block is provided at the upper end of the slide rod. The right end of the second electric push rod is fixedly connected to one side of the push block. A second motor is provided at the lower end of the slide rod. An eccentric disc is fixedly connected to the output shaft of the second motor. An eccentric hydraulic rod is provided on one side of the lower surface of the eccentric disc, and a clamping component is provided on the right side of the lower surface of the synchronization plate.

[0009] Preferably, the clamping assembly includes two clamping columns, both of which are slidably connected to the synchronization plate. Each of the two clamping columns has a limit block fixedly connected to its upper end and a clamping block provided at its lower end. Each of the two clamping columns is fitted with a buffer spring, the upper end of which is connected to the synchronization plate and the lower end of which is connected to the clamping block.

[0010] Preferably, a fixing block is fixedly connected to the upper end of the first motor output shaft, and a fixing block is also fixedly connected to the lower surface of the mounting plate. The two fixing blocks are connected by multiple bolts.

[0011] Preferably, the rotating device includes a connecting rod, the lower end of which is fixedly connected to a column or support column, and the upper end of which is rotatably connected to a roller, the upper end of which is in contact with the surface of a first annular groove or a second annular groove.

[0012] Preferably, the inner wall of the mounting groove is provided with multiple heat dissipation holes.

[0013] The shoe upper manufacturing machine proposed in this utility model has the following advantages: The processing device, when the second motor is started, can change the position of the eccentric hydraulic rod, thereby enabling processing of multiple positions on the shoe upper. By activating the second electric push rod, the eccentric hydraulic rod is moved left and right via the push block and slide rod, allowing the machine to operate flexibly. The clamping assembly, through the clamping block, clamps against the shoe upper. The buffer spring ensures elastic contact between the clamping block and the shoe upper, preventing damage. The rotating device, when the mounting plate rotates, supports the mounting plate by having one set of rollers abut against the corresponding first annular groove and another set of rollers abut against the corresponding second annular groove, ensuring stable rotation of the mounting plate.

[0021] The processing device includes a first electric push rod 15, which is located directly above the heel of the rightmost shoe upper 13. A synchronization plate 16 is fixedly connected to the lower end of the first electric push rod 15. An upper block 17 is provided on the left side of the upper surface of the synchronization plate 16, and a second electric push rod 18 is provided on the right side surface of the upper block 17. A sliding groove 19 is opened on the surface of the synchronization plate 16, and a sliding rod 20 is slidably connected inside the sliding groove 19. A push block 21 is provided at the upper end of the sliding rod 20. The right end of the second electric push rod 18 is fixedly connected to one side surface of the push block 21. A second motor 32 is provided at the lower end of the sliding rod 20. An eccentric disk 33 is fixedly connected to the output shaft of the second motor 32. An eccentric hydraulic rod 22 is provided on one side of the lower surface of the eccentric disk 33, and a clamping component is provided on the right side of the lower surface of the synchronization plate 16.

[0022] The clamping assembly includes two clamping columns 23, both of which are slidably connected to the synchronization plate 16. Limiting blocks 24 are fixedly connected to the upper ends of both clamping columns 23, and clamping blocks 25 are provided at the lower ends of both clamping columns 23. Buffer springs 26 are fitted on the outside of both clamping columns 23. The upper ends of the buffer springs 26 are connected to the synchronization plate 16, and the lower ends of the buffer springs 26 are connected to the clamping blocks 25.

[0023] A fixing block 27 is fixedly connected to the upper end of the output shaft of the first motor 6, and a fixing block 27 is also fixedly connected to the lower surface of the mounting plate 7. The two fixing blocks 27 are connected by multiple bolts 28. The connection by bolts 28 facilitates the inspection and maintenance of the first motor 6 and the components on the mounting plate 7.

[0024] The rotating device includes a connecting rod 29, the lower end of which is fixedly connected to the column 4 or the support column 8, and a roller 30 is rotatably connected to the upper end of the connecting rod 29. The upper end of the roller 30 contacts the surface of the first annular groove 9 or the second annular groove 10. By having one set of rollers 30 roll in contact with the first annular groove 9 and another set of rollers 30 roll in contact with the second annular groove 10, the friction between the mounting plate 7 and the column 4 and the support column 8 can be reduced.

[0025] The inner wall of the mounting slot 5 is provided with multiple heat dissipation holes 31. The multiple heat dissipation holes 31 can dissipate heat from the first motor 6.

[0026] In this invention, during use, a suitable shoe upper mold 12 is first selected according to the specifications of the shoe upper 13. Then, the shoe upper mold 12 and the clamping block 11 are clamped together, and shoe uppers 13 are clamped inside multiple shoe upper molds 12, with the heel of the shoe upper 13 facing inward. Through the processing device, the first electric push rod 15 is activated, which drives the synchronous plate 16 to move downward. The two clamping blocks 25 first press the rightmost shoe upper 13. At this time, the eccentric hydraulic rod 22 is located directly above the heel of the rightmost shoe upper 13, and the heel of the rightmost shoe upper 13 is processed. How to process it is existing technology and will not be described here. When the second motor 32 is activated, the position of the eccentric hydraulic rod 22 can be changed. This allows for processing of multiple areas of the shoe upper. By activating the second electric push rod 18, the push block 21 and slide rod 20 drive the eccentric hydraulic rod 22 to move left and right. The eccentric hydraulic rod 22 can move left and right, making the shoe upper machine flexible in operation. When the rightmost shoe upper 13 is processed, the first motor 6 is activated simultaneously. The output shaft of the first motor 6 drives the mounting plate 7 to rotate. Each time the first motor 6 is activated, it can complete the exchange of shoe upper mold 12 and shoe upper 13. The above processing operation is repeated. During the processing, the worker replaces the processed shoe upper 13. Compared with conventional shoe upper making machines, it can simultaneously complete the processing of the shoe upper and the replacement of the shoe upper 13. The clamping component, with clamping block 25 clamping against the upper 13, and buffered by the buffer spring 26, ensures that the clamping block 25 makes elastic contact with the upper 13, thus avoiding damage to the upper 13. The rotating device, when the mounting plate 7 rotates, provides support for the mounting plate 7 by having one set of rollers 30 abut against the corresponding first annular groove 9 and another set of rollers 30 abut against the corresponding second annular groove 10, ensuring that the mounting plate 7 can rotate stably.
