Description

Technical Field

[0001] This utility model belongs to the field of shoemaking technology and relates to a footrest for a leather edge trimming machine used in shoemaking. Background Technology

[0002] In the shoemaking industry, the upper is made up of multiple upper pieces. To ensure that the thickness at the joint of the upper pieces is appropriate and to guarantee the strength of the connection, a leather edge-shaving machine is used to thin the edges of the upper pieces before joining them together.

[0003] The existing edge trimming machine includes a frame and, fixed on the frame and arranged sequentially along the moving direction of the edge piece, a support foot, a transmission wheel, and a cutting blade. The support foot structure is as follows: Figure 1 As shown, it includes a connecting part for mounting on the frame and a vertical working end face for abutting against the side plate. The positional relationship of the support foot, transmission wheel, and cutting tool is as follows: Figure 2 As shown, when using a beveling machine to cut the edge of a sheet, the operator holds the sheet horizontally with its edge against the working end face of the foot. Under the horizontal limit of the working end face, the operator manually moves the sheet horizontally along the working end face to above the conveyor wheel. Through the rolling conveyor wheel, the sheet continues to be conveyed forward. At the same time, the cutting blade thins the front edge of the sheet, thus achieving the cutting of the thickness at the joint of the sheet.

[0004] The following problems may occur in actual use: 1. Because the side plate is made of soft material, although the foot can restrict the horizontal position of the side plate, it cannot restrict the vertical position of the side plate. The difference in the vertical position of the side plate can easily lead to the difference in cutting thickness, making it difficult to control the cutting thickness; 2. After the side plate is against the working end face of the foot, it needs to be cut by the drive of the conveyor wheel. In the existing equipment, the distance between the foot and the conveyor wheel is too large. The operator has to press the edge of the side plate against the foot and then manually move the side plate to contact the conveyor wheel. During this process, it is difficult to control the positioning position of the side plate, which makes the position of the side plate entering the cutter different, thereby reducing the cutting accuracy. Summary of the Invention

[0005] The purpose of this invention is to provide a footrest for a leather edge trimming machine for shoemaking. This invention can control the cutting thickness and width when cutting the edge of the upper piece, and it is easy to control during edge trimming. It is simple, practical, and convenient for employees to operate.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A footrest for a leather edge trimming machine for shoemaking includes an elongated hole along the length of the footrest and a working end face located at one end of the footrest. A horizontal pressure plate is fixed on the top of the working end face. Below the working end face, a recessed groove matching the outer dimensions of the transmission wheel is provided.

[0008] The pressure plate extends from the working end face along the length of the foot.

[0009] As a limitation, the width of the pressure plate is greater than or equal to the width of the working end face.

[0010] As a second limitation, the side of the working end face used to resist the side plate is provided with a first arc surface.

[0011] As a third limitation, a second arc surface is provided on the side of the pressure plate used to resist the side plate.

[0012] As a fourth limitation, the maximum depth of the recessed groove is equal to the radius of the conveyor wheel.

[0013] As a further limitation, the height of the working end face is the sum of the thickness of the pressure plate and the maximum depth of the recessed groove.

[0014] As a limitation on the pressure plate, the upper surface of the pressure plate is provided with millimeter scale lines along the extension direction of the elongated hole.

[0015] The technological advancements achieved by this invention compared to existing technologies, due to the adoption of the aforementioned technical solution, are as follows:

[0016] (1) This utility model achieves the limitation of the horizontal and vertical direction of the side sheet by adding a pressure plate, and reduces the distance between the foot and the conveyor wheel by setting a recessed groove, thus completing the control of the cutting thickness and width of the side sheet;

[0017] (2) The present invention adds a first arc surface to the side of the working end face used to resist the side piece, which can effectively prevent the workers from scratching the side piece when placing it;

[0018] (3) The present invention adds a second arc surface to the side of the pressure plate used to block the side panel, which can effectively prevent workers from being scratched when placing the side panel and improve safety.

[0019] (4) By controlling the thickness of the pressure plate and the maximum depth of the recessed groove, this utility model ensures that the side piece is subjected to the maximum pressure of the pressure plate when passing through the conveyor wheel, which greatly increases the friction between the side piece and the conveyor wheel and reduces the workload of the workers.

[0020] (5) The present invention sets a scale line on the upper surface of the pressure plate. By adjusting the bolt at the fixed position of the elongated hole, the width of the cutting of the side plate can be adjusted conveniently and quickly.

[0021] This utility model belongs to the field of shoemaking technology. It can control the cutting thickness and width when cutting the edge of the upper piece, and it is easy to control during edge trimming. It is simple, practical and convenient for employees to operate. Attached Figure Description

[0029] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0030] like Figures 3 to 4 As shown, this embodiment includes an elongated hole 1 along the length of the foot rest and a working end face 2 located at one end of the foot rest. The working end face 2 is vertical during operation, and a pressure plate 3 is fixed on the top of the working end face 2. The pressure plate 3 extends from the working end face 2 along the length of the foot rest, and the width of the pressure plate 3 is the same as the width of the working end face 2. The pressure plate 3 on the foot rest and the working end face 2 cooperate with the worktable to form a groove that can accommodate the passage of the support piece.

[0031] To facilitate identification of the horizontal limit of the support plate, a 10 mm scale line is provided on the upper surface of the pressure plate 3, and the scale line is set along the extension direction of the elongated hole.

[0032] A recessed groove 6 is also provided below the working end face 2 to facilitate the installation of the conveyor wheel closer to the foot, reducing the gap between the foot and the conveyor wheel and ensuring the uniformity of the positioning of the support piece during the conveying process. The overall shape of the recessed groove 6 corresponds to the outer dimensions of the conveyor wheel, and the conveyor wheel, after installation, can fit perfectly into the recessed groove 6 without rubbing against the foot. The maximum depth of the recessed groove 6 is equal to the radius of the conveyor wheel.

[0033] To ensure the firmness between the conveyor wheel and the support plate when the conveyor wheel drives the support plate, the height of the working end face 2 is the sum of the thickness of the pressure plate 3 and the maximum depth of the recessed groove 6.

[0034] To prevent the sharp points on the working end face 2 and the pressure plate 3 from damaging the side sheet and causing injury to personnel, a first arc surface 4 is provided on the side of the working end face 2 used to resist the side sheet, and a second arc surface 5 is provided on the side of the pressure plate 3 used to resist the side sheet.

[0035] In this embodiment, the height of the working end face 2 is 10mm, the thickness of the pressure plate 3 is 3mm, the axis of the conveyor wheel is located at one corner of the working end face 2, and the radius of the conveyor wheel is 7mm.

[0036] In this embodiment, bolts are first used to pass through the elongated hole 1 to fix the support foot to the workbench, with the working end face 2 of the support foot facing the worker. The pressure plate 3 on the support foot and the working end face 2 cooperate with the workbench to form a groove that can accommodate the passing piece of fabric. The worker needs to manually feed the fabric into the groove. The first arc surface 4 and the second arc surface 5 can effectively protect the fabric and the worker's hands. The edge of the fabric slides horizontally against the working end face 2, and the workbench and pressure plate 3 provide good vertical upper limit. When the fabric contacts the conveyor wheel, it will slide horizontally under the drive of the conveyor wheel to complete the cutting. Since the height of the working end face 2 is equal to the sum of the thickness of the pressure plate 3 and the radius of the conveyor wheel, the fabric is squeezed by the conveyor wheel and pressure plate 3 when passing through the conveyor wheel, so that the fabric can be firmly fixed on the conveyor wheel. This ensures the completion of the cutting and facilitates the operation of the worker, reducing the worker's workload.

[0037] If it is necessary to adjust the horizontal limit of the side panel, loosen the fixing bolts and adjust the horizontal limit of the side panel by the scale on the upper surface of the pressure plate 3.

[0038] In this embodiment, the scale lines on the surface of the pressure plate 3 are 10 mm scale lines, which can be adjusted according to actual conditions, as long as the cutting width is met. The width of the pressure plate 3 is the same as the width of the working end face 2, and can be adjusted according to actual conditions, as long as the width of the pressure plate 3 is greater than or equal to the width of the working end face 2.

[0039] In summary, this embodiment can control the cutting thickness and width when cutting the edge of the sheet, and it is easy to control during edge trimming. It is simple, practical, and convenient for employees to operate.
