Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This embodiment provides a technical solution: a shoe cutting machine, including a worktable 1 and a material feeding mechanism 4; Workbench 1: A four-column hydraulic press 2 is provided on its upper side. An installation box 3 is provided on the upper front side of the workbench 1. An external oil pump is connected to the oil inlet and outlet of the four-column hydraulic press 2. A vertical clearance opening is provided on the front side of the machine table of the four-column hydraulic press 2. A controller 9 is located on the right side of the workbench 1. The input terminals of the solenoid valve and relief valve on the four-column hydraulic press 2 are electrically connected to the output terminal of the controller 9, and the input terminal of the controller 9 is electrically connected to an external power source. A hydraulic pump for control is placed around the workbench 1. When the hydraulic pump operates, it converts mechanical energy into hydraulic energy, causing the hydraulic oil to generate pressure in a closed pipeline. The high-pressure hydraulic oil enters the upper or lower chamber of the hydraulic cylinder of the four-column hydraulic press 2 through the solenoid valve, relief valve, and other control components at the upper end of the four-column hydraulic press 2. According to Pascal's law, hydraulic... The oil pressure is uniformly transmitted in the closed system, driving the piston in the hydraulic cylinder to move. If the oil enters the upper chamber of the hydraulic cylinder of the four-column hydraulic press 2, the piston drives the machine table to move downward to realize the cutting action. If the oil enters the lower chamber, the piston drives the machine table to return to its original position. The input ends of the control components such as the solenoid valve and overflow valve at the upper end of the four-column hydraulic press 2 are electrically connected to the output end of the controller 9. When the machine table of the four-column hydraulic press 2 moves up and down, it is precisely guided by the four vertical columns to ensure that the machine table and the table surface of the worktable 1 always remain parallel, thus ensuring processing accuracy. The upper mold 7 is fixedly connected to the middle of the lower surface of the four-column hydraulic press 2, and the lower mold 8 is fixedly connected to the middle of the upper surface of the worktable 1. The upper mold 7 and the lower mold 8 are vertically aligned. When the cutting machine is needed, the leather material for shoe making that needs to be cut can be placed on the upper surface of the worktable 1 through the unwinding machine. When it moves between the upper mold 7 and the lower mold 8, the controller 9 can be adjusted to start the four-column hydraulic press 2. The machine base of the four-column hydraulic press 2 moves down, driving the upper mold 7 to apply downward pressure. The die cutting edge on the upper mold 7 cooperates with the cutting groove on the lower mold 8 to separate the shoe material along the mold outline. The ejector mechanism 4 includes a mounting base 42, a gear 43, a slide groove 45, a slider 46, a movable rack plate 47, and a push rod 48. The slide groove 45 is located on the rear side wall of the mounting box 3. The slider 46 is slidably connected inside the slide groove 45. The push rod 48 is located at the lower end of the slider 46. The movable rack plate 47 is fixedly connected to the front side of the slider 46. The mounting base 42 is located in the middle of the mounting box 3. The gear 43 is rotatably connected inside the mounting base 42. The gear 43 meshes with the movable rack plate 47. The ejector mechanism 4 also includes a fixed rack plate 44, which is fixedly connected to the lower side of the front side wall of the mounting box 3. The teeth on plate 44 mesh with the teeth on gear 43. The push rod 48 passes vertically through the round hole opened in the lower side wall of the mounting box 3. The pushing mechanism 4 also includes a connecting arm 41 and a transverse clearance opening 49. The transverse clearance openings 49 are respectively opened on the lower side of the left side wall and the lower side of the right side wall of the mounting box 3. The left and right sides of the mounting base 42 are respectively fixedly connected to the connecting arm 41. The two connecting arms 41 pass horizontally through the transverse clearance openings 49 located on the same side. The ends of the two connecting arms 41 are fixedly connected to the inner wall of the vertical clearance opening. During the downward movement of the four-column hydraulic press 2, the mounting base 42 will be driven to move downward synchronously through the connecting arm 41. During the movement, gear 43 maintains meshing with fixed rack plate 44. As mounting base 42 moves downward, it drives gear 43 to rotate clockwise. During this time, gear 43 maintains meshing with moving rack plate 47, which in turn drives slider 46 to move downward, thereby driving push rod 48 to move downward and extend into ejector mold 5. As the four-column hydraulic press 2 retracts, push rod 48 also returns to its original position. If the cutting machine is operating in harsh environments, a bellows-type telescopic device needs to be fixedly connected to the upper and lower surfaces of mounting box 3 respectively. The ends of the two accordion-style telescopic covers are fixed to the outer surface of the connecting arm 41. As the connecting arm 41 moves vertically up and down, the two accordion-style telescopic covers will also adapt to the expansion and contraction, sealing the front, back, left, and right sides of the mounting box 3 and preventing the lateral clearance opening 49 from being directly exposed. This prevents dust and other contaminants from entering the mounting box 3 along the lateral clearance opening 49 and contaminating the outer surfaces of the gear 43, fixed rack plate 44, and movable rack plate 47, thereby affecting the transmission effect of the gear 43, fixed rack plate 44, and movable rack plate 47. The gear 43, fixed rack plate 44, and movable rack plate 47 should be cleaned and maintained regularly. The upper surface of the workbench 1 is provided with a material ejection mold 5 on the front side, and a material discharge channel 6 is provided on the lower side of the material ejection mold 5. The material ejection mold 5 is vertically aligned with the push rod 48. When the cut leather material moves to the upper side of the material ejection mold 5, a material ejection hole is opened on the upper surface of the material ejection mold 5. The cut leather material will be pushed into the material discharge channel 6 through the material ejection hole and discharged along the material discharge channel 6. The waste material will move forward along the upper surface of the workbench 1, automatically separating the waste material from the finished product.

[0016] The working principle of the shoe cutting machine provided by this utility model is as follows: When the cutting machine is needed, the leather material for shoe making to be cut can be placed on the upper surface of the workbench 1 through the unwinding machine. When it moves between the upper mold 7 and the lower mold 8, the controller 9 can be adjusted to start the four-column hydraulic press 2. The machine platform of the four-column hydraulic press 2 moves down, driving the upper mold 7 to apply downward pressure. The die cutting edge on the upper mold 7 cooperates with the cutting groove on the lower mold 8 to separate the shoe material along the mold outline. During the downward movement of the machine platform of the four-column hydraulic press 2, the mounting base 42 will move downward synchronously through the connecting arm 41. During this period, the gear 43 and the fixed rack plate 44 remain meshed. In the process of the mounting base 42 moving downward, it will drive the gear 43 to rotate clockwise. During this period, the gear 43 will maintain a meshing relationship with the moving rack plate 47. At this time, the moving rack plate 47 will drive the slider 46 to move downward, which in turn will drive the push rod 48 to move downward and extend into the unloading mold 5. As the machine table of the four-column hydraulic press 2 retracts, the push rod 48 will also return to its original position. When the cut leather material moves to the upper side of the unloading mold 5, it will push the cut leather into the discharge channel 6 and discharge it along the discharge channel 6. The waste material will move forward along the upper surface of the worktable 1, automatically separating the waste material from the finished product.

[0017] It is worth noting that the controller 9 disclosed in the above embodiments uses a single-chip microcomputer as its core chip, specifically the STC89C54. The four-column hydraulic press 2 can be freely configured according to the actual application scenario. It is recommended to use an HG series four-column hydraulic press with a cutting force of 30T. The controller 9 controls the operation of the four-column hydraulic press 2 using methods commonly used in the prior art.

[0018] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
