Description

Technical Field

[0001] The utility model relates to the technical field of slipper processing, and particularly relates to an edge grinding device for producing PU slippers. Background Art

[0002] PU slippers refer to slippers made of polyurethane (abbreviated as PU) materials. Polyurethane is a synthetic organic polymer material with the following characteristics: light weight, softness, good elasticity, wear resistance, shock absorption, anti-slip, temperature resistance, chemical stability, environmental protection, breathability, etc., making it one of the preferred materials for making slippers.

[0003] In modern shoe-making industry, especially for the production of PU (polyurethane) slippers, an efficient and precise edge treatment process is one of the key links to improve product quality and production efficiency. Traditional manual or simple mechanical edge grinding often fixes the slippers and removes burrs and grinds the edges along the perimeter of the slippers with a razor, which cannot ensure stable gripping during the edge grinding process and cannot effectively collect the debris generated during grinding, resulting in direct discharge of the debris polluting the environment. Summary of the Utility Model

[0004] In view of this, the utility model provides an edge grinding device for producing PU slippers, which can not only fixedly clamp the slippers through a clamping assembly, rotate the slippers through a rotating turntable and a pressing plate, so that a grinding shaft and a razor perform precise edge grinding and removal work on the perimeter of the slippers, but also adsorb the debris generated during grinding through an adsorption assembly and collect it inside a collection pipeline, optimize the management of waste, and thus reduce the pollution to the environment.

[0005] To solve the above technical problems, the utility model provides an edge grinding device for producing PU slippers, which includes a processing platform, and an edge grinding mechanism for processing the slippers is arranged on the processing platform. The edge grinding mechanism includes a clamping assembly arranged inside the processing platform for fixing the slippers and an adsorption assembly arranged at the bottom of the processing platform for discharging the waste chips after edge grinding.

[0006] The clamping assembly includes a fixed frame, on which a turntable is rotatably provided. A column is provided on the right side of the turntable, and an extension column is provided at the top of the column. A hydraulic push rod is fixedly provided on the extension column, and a pressing plate is connected to the tail end of the hydraulic push rod. Two gaskets are symmetrically provided on the pressing plate; the adsorption assembly includes a collection pipe and a placement table provided at the bottom of the processing platform. An air extractor is provided on the placement table. Through the combined use of the clamping assembly and the adsorption assembly, the edge grinding work of PU slippers is optimized, so that the slippers can be clamped by the rotatable clamping assembly, and during edge grinding, the four sides of the slippers can be precisely ground in a controllable manner, and the waste chips generated during the grinding process are adsorbed by the adsorption device, and the waste chips are centrally collected, optimizing the management of waste and avoiding environmental pollution.

[0007] An installation table is provided at the bottom of the fixed frame, and a rotating motor is fixedly provided on the installation table. The end of the output shaft of the rotating motor is connected to the bottom of the turntable. The turntable is driven to rotate by the rotating motor, and the grinding position of the razor and the grinding shaft on the slippers is adjusted by rotation.

[0008] The pressing plate and the hydraulic push rod are connected by a bearing. Two connecting rods are symmetrically provided on the pressing plate, and a collar is connected to the tail ends of the two connecting rods. The pressing plate and the hydraulic push rod are connected by a bearing, so that when the hydraulic push rod pushes the pressing plate to clamp the slippers, it rotates in coordination with the turntable, and the two connecting rods and the collar assist the pressing plate to rotate.

[0009] The collar is sleeved on the push rod of the hydraulic push rod. A control rod is connected to the tail end of the hydraulic push rod, and a handle is connected to the tail end of the control rod. The hydraulic push rod in the processing platform is controlled through the extended control rod and the handle.

[0010] A valve is connected to the bottom of the collection pipe. An air duct is connected between the input end of the air extractor and the collection pipe, and a filter screen is connected in the air duct. The bottom of the collection pipe is blocked by the valve, so that when the air extractor rotates, the debris in the processing platform is adsorbed, and under the filtration of the filter screen, it falls on the top of the valve. After the grinding is completed, the valve is opened to centrally process the waste chips.

[0011] The clamping assembly further includes a grinding module, and the grinding module includes two electric cylinders provided on the fixed frame.

[0012] The telescopic end of an electric cylinder is connected with a tool holder, and a razor is fixedly arranged inside the tool holder. The telescopic end of another electric cylinder is connected with a fixed frame, and a servo motor is arranged on the top of the fixed frame. The output end of the servo motor is connected with a grinding shaft. The positions of the razor and the grinding shaft are adjusted by the two electric cylinders, so that the razor and the grinding shaft can adapt to the edge grinding work of different styles of slippers. And through the control of the electric cylinders, when the turntable drives the slippers to rotate, the grinding position can be accurately adjusted to prevent waste of materials.

[0013] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0014] 1. When the utility model is in use, the slippers are clamped and fixed by the turntable and the pressing plate equipped with a rotating shaft, and at the same time, the slipper rack is rotated. When the grinding module grinds the slippers, the grinding position of the slippers is adjusted, so as to accurately grind the slippers and prevent waste of materials.

[0015] 2. When the utility model is in use, the waste chips generated during grinding are adsorbed and collected by the induced draft fan in the adsorption assembly, and the waste chips are centrally collected through the valve. After the grinding is completed, the valve is opened to centrally process the waste chips.

[0016] 3. When the utility model is in use, the positions of the razor and the grinding shaft are adjusted by the electric cylinders in the grinding module, so that the razor and the grinding shaft closely fit around the slippers, and the razor and the grinding shaft are adjusted along the contour of the slippers.
