Description

Technical Field

[0001] The utility model relates to a pattern making machine, in particular to a pressing frame structure of a school uniform pattern making machine. Background Art

[0002] A pattern machine is a type of clothing processing equipment that can weave various silk, cotton, chemical fiber and other fabrics by regulating the lifting, movement and matching of rail hooks, rapiers, shuttles and other components. It can also process various embroidery, jacquard and other patterns on clothing.

[0003] During the processing, the clothing pieces to be processed are first placed on the work surface of the pattern machine, and then the pressing frame is driven by the pressing mechanism to press and fix the clothing pieces. The pressing method is used to avoid displacement and bending deformation of the clothing pieces during the processing, so as to ensure the processing quality of the clothing pieces. However, since the existing pressing mechanism has a relatively complex design structure and is generally driven by a power source, the production cost of the existing pressing mechanism is relatively high, and the complexity of the structure and intelligent control also greatly increase its failure rate, resulting in the existing pressing frame structure being unsuitable for later installation on some old equipment; and once a failure occurs, more professional personnel are required to repair it, and general production enterprises are rarely equipped with professional maintenance personnel. As a result, the existing structure does not have good practicality for some special working conditions. Based on the above problems, the present invention was conceived. Utility Model Content

[0004] The purpose of the utility model is to provide a school uniform pattern machine frame pressing structure, which has a low failure rate and is convenient for later installation and maintenance, so as to improve the practicability and processing efficiency of the structure.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a school uniform pattern machine pressing frame structure, including a fixed seat for fixing to a pattern machine base and a pressing frame body connected to the fixed seat, the pressing frame body and the fixed seat are rotatably connected to allow the pressing frame body to reciprocate in a vertical direction, a manual pressing and holding component is provided between the pressing frame body and the fixed seat, the manual pressing and holding component cooperates with the rotating connection between the pressing frame body and the fixed seat to give the pressing frame body a rotation stroke and a pressing stroke that drives the pressing frame body to be pressed against the work surface.

[0006] By adopting the above technical solution, the separation of the pressing frame body and the work surface is achieved through the formed rotation stroke, so as to facilitate the picking and placing operation of the clothing pieces to be processed. After the clothing pieces to be processed are placed on the work surface, the pressing frame body is flipped to switch it from the rotation stroke to the pressing stroke, and then the pressing operation of the clothing pieces on the work surface can be completed by cooperating with the set manual pressing and holding assembly. The structure is simple, the failure rate is low, and it is more convenient for simple maintenance in the later stage. The later installation operation of the pressing frame structure can be completed by fixing the fixing seat to the pattern machine base through fasteners, so that the structure can better adapt to special working conditions and application environments, thereby improving the practicality of the structure.

[0007] It is further configured that: there is damping rotation between the pressing frame body and the fixing seat, and when the pressing frame body is in a rotation stroke state, the manual pressing and holding assembly will not interfere with the rotation of the pressing frame body.

[0008] By adopting the above technical solution, the real-time positioning of the pressing frame body during the flipping is given by the damping rotation method, so that the pressing frame body will not interfere with the normal operation of other components, thereby improving the convenience of operation. And the pressing frame body in the rotation stroke is prevented from being subjected to the force from the manual pressing component in a non-interference manner, so that it will not interfere with the real-time positioning function of the pressing frame body during the flipping.

[0009] It is further configured as follows: the pressure frame body and the fixed seat are rotationally connected via a rotating shaft, the manual pressing assembly includes an elastic pressing member with two connecting ends and a detachable force-bearing structure, one connecting end of the elastic pressing member is connected to the pressure frame body, and the other connecting end is connected to the fixed seat via the force-bearing structure, when the force-bearing structure connects the fixed seat and the elastic pressing member, the elastic pressing member imparts a pressing force to the pressure frame body.

[0010] By adopting the above technical solution, when the force-bearing structure is in a connected state, the two ends of the elastic pressing piece are limited and thus in a force storage state, thereby driving the pressing frame body to be pressed against the work surface; when the force-bearing structure is in a disengaged state, the two ends of the elastic pressing piece are not limited and thus in a free state without force storage, so that the manual pressing and holding component will not interfere with the damping rotation positioning function of the pressing frame body.

[0011] It is further configured as follows: the force-bearing structure includes a force-bearing pin arranged at the connecting end of the elastic pressing piece and a force-bearing hole arranged at the fixing seat and for the force-bearing pin to be inserted into.

[0012] By adopting the above technical solution, the force-bearing pin is inserted into the force-bearing hole to realize the detachable fixed connection between the elastic pressing member and the fixing seat, which has a simple structure and is easy to operate.

[0013] It is further configured as follows: an elastic docking groove with an opening is provided on the pressure frame body, the elastic pressing piece is a torsion spring, the opening of the elastic docking groove is arranged parallel to the axis of the rotating shaft, when the torsion spring is sleeved on the rotating shaft, one of the connecting ends of the torsion spring can enter and exit the elastic docking groove, and an abutment block is provided in the elastic docking groove for limiting the torsion spring from escaping from the elastic docking groove.

[0014] By adopting the above technical solution, the torsion spring is sleeved on the rotating shaft, and then one of the connecting ends of the torsion spring is embedded into the elastic docking groove along the rotating shaft, so as to realize the convenient assembly of the torsion spring and the pressing frame body. Then, the abutment block is provided to limit the separation of the torsion spring and the elastic docking groove, thereby making it easier to disassemble and assemble the manual pressing assembly.

[0015] It is further configured as follows: a plurality of adjusting waist-shaped holes are provided on the fixing seat, and each of the adjusting waist-shaped holes is vertically arranged.

[0016] By adopting the above technical solution, the setting of the waist-shaped hole is adjusted to adjust the distance between the pressing frame body and the work surface, so as to ensure that the pressing frame body can stably press and hold the clothing pieces on the work surface.

[0017] In summary, the utility model has the following beneficial effects: the utility model has a low failure rate and is convenient for later installation and maintenance, thereby improving the practicality and processing efficiency of the structure. BRIEF DESCRIPTION OF THE DRAWINGS
