Description

Technical Field

[0001] The utility model relates to the technical field of belt processing, in particular to an edge trimming device for belts. Background Art

[0002] At present, in the production process of belts, the rolled leather needs to be initially cut first, and the rolled leather needs to be divided into leather pieces of a certain width. The leather pieces are cut by a slitting machine into semi-finished leather strips with a width of 5-10 belt bodies. The width of the belt body and the cross-sectional surfaces on both sides of the belt body are rough after slitting, which cannot meet the requirements of belt fitting. It is necessary to further chamfer the cross-sectional surfaces on both sides of the belt body to meet the requirements of smooth cross-sectional surfaces on both sides of the belt, so as to facilitate other subsequent processing of the belt. However, the existing chamfering device can only operate on one side, so both sides of the belt body of a belt need to be chamfered twice, which is inefficient. Moreover, during the chamfering process of the belt, it is easy to mix in the situation that only one side of the individual belt is chamfered, which causes belt defects in the subsequent processing of the belt. Utility Model Content

[0003] The utility model aims to provide an edge trimming device for a belt, aiming to solve the problem that the existing belt can only be edge trimmed on one side, thereby improving the efficiency of the belt edge trimming.

[0005] Furthermore, a motor is coaxially provided on the rotating wheel, and the motor is installed on the side wall of the support. The power output shaft of the motor is connected to the rotating wheel through the side wall of the support, and the rotation of the rotating wheel is driven by the motor.

[0006] Furthermore, the upper roller comprises a first upper roller, a second upper roller and a third upper roller, the gap between the first upper roller and the second convex plate is larger than the gap between the second upper roller and the second convex plate, the gap between the second upper roller and the second convex plate is the same as the gap between the third upper roller and the second convex plate, and thus, in the process of the belt entering the channel for edge chamfering, the belt is initially positioned by the first upper roller and then pressed against the surface of the rotating wheel by the second upper roller and the third upper roller, so that the belt can move toward the tool driven by the rotation of the rotating wheel.

[0007] Furthermore, a work-shaped seat for supporting and positioning the belt is provided between the tools, and the work-shaped seat includes an upper support surface, and the support surface is flush with the surfaces of the first convex plate and the second convex plate, and the bottom of the work-shaped seat is provided with two wings for fixing, and the two wings are provided with second fixing screws and fixedly connected with the support. After the belt is edge-cut by the tool, the belt is supported by the support surface flush with the surfaces of the first convex plate and the second convex plate, so that the belt remains straight and positioned to move, thereby ensuring that the tool can be positioned to cut the edges on both sides of the belt.

[0008] Furthermore, the base is provided with a pair of first adjustment slots for adjusting the positioning of the supports, and two supports arranged opposite to each other are adjustably fixed to the first adjustment slots of the base by third fixing screws. Through the first adjustment slots, the two supports can form an adjustment structure for adjusting the distance between them, and in the process of trimming the belts of different widths, the distance between the supports can be adjusted to adapt to the different widths of the belts.

[0009] Furthermore, the support is provided with a support plate for fixing the tooling seat, and the support plate is provided with a pair of second adjustment slots. When the distance between the two supports is adjusted, the tooling seat is correspondingly adjusted and fixed through the second adjustment slots on the support plate, so that the support surface of the tooling seat can be guaranteed to be located between the two tools.

[0010] Furthermore, the bottom of the support is provided with side holes, and a waste tray for receiving waste is provided between the side holes. The belt edge waste generated during the belt edge cutting process is collected by the waste tray, and the waste tray is conveniently taken out and processed by using the side holes of the support.

[0011] The utility model discloses an edge trimming device which can trim the edges of two sides of a belt at the same time by arranging two oppositely arranged cutting tools, thereby greatly improving the speed and efficiency of the edge trimming of the belt. The edge trimming device can meet the requirements of adjusting the belt width of belts of different specifications through the adjustable structure of the support, thereby greatly improving the application of the edge trimming device.

[0012] The utility model uses a work-shaped seat arranged between the cutting tools, so that one side of the belt after edge trimming is supported by the supporting surface of the work-shaped seat, thereby ensuring that the belt remains straight during the edge trimming process, thereby ensuring accurate positioning and edge trimming of the belt, and the work-shaped seat is also adjustable and fixedly installed through the second adjustment groove, so that it can well adapt to the corresponding adjustment and installation of the work-shaped seat after the adjustment distance of the support.

A convex edge 215 is provided at the front end of the support 21, and a tool holder 23 is installed on the convex edge 215. The convex edge 215 is plugged and installed in the tool holder 23. A first fixing screw 24 is provided on the upper part of the tool holder 23 to be fixed and locked on the convex plate 215 plugged in the tool holder 23 to form a fixed connection Next, a tool 22 is installed on the surface of the tool holder 23, and the blade of the tool 22 faces the entry channel in the forward direction of the belt 6. The tools 22 on the two supports 21 are aligned with the moving belt 6 from both sides, so that the edge is cut in the process of the belt 6 moving toward the tool 22 from the entry. The two supports 21 are provided with a rotating wheel 3 that drives the belt 6 to move toward the tool 22 below the second convex plate 214. An upper roller 26 is rotatably provided above the rotating wheel 3. The upper roller 26 is rotatably installed between the roller holes 214 on the baffle 211, and the upper roller 26 is located above the second convex plate 214.

[0024] In order to ensure that the belt 6 remains straight during the process of edge trimming on both sides, thereby ensuring the accurate positioning and edge trimming of the belt 6, a work-shaped seat 25 for supporting and positioning the belt 6 is provided between the cutters 22 on the support 21. The work-shaped seat 25 includes an upper support surface 251, and the support surface 251 is flush with the surfaces of the first convex plate 212 and the second convex plate 214. The bottom of the work-shaped seat 25 is provided with two wings 252 for fixing. The two wings 252 are provided with second fixing screws 253 and are fixedly connected to the support 21. Figure 5 After the belt 6 is chamfered by the tool 22, the belt 6 is supported by the support surface 251 flush with the surface of the first convex plate 212 and the second convex plate 214, so that the belt 6 can maintain a straight positioning and movement, thereby ensuring that the tool 22 can be positioned to chamfer both sides of the belt 6. Correspondingly, a support plate 216 for fixing the work-shaped seat 25 is provided on the support plate 216, and a pair of second adjustment grooves 217 are opened on the support plate 216.
