Description

Technical Field

[0001] The utility model relates to the field of umbrella processing equipment, in particular to an automatic edge-collecting and rolling machine. Background Art

[0002] Umbrella is a tool that people often use in their daily lives to protect themselves from the sun and rain. The structure of an umbrella is generally composed of four parts: an umbrella handle, an umbrella stick, an umbrella rib, and an umbrella cover.

[0003] Among them, the umbrella cover is an important part of the umbrella, which is responsible for sheltering from rain. The fabrics used are generally polyester plain cloth, polyester silver tape, impact cloth, nylon cloth, etc. In the production and processing of umbrellas, the cloth of each umbrella is cut from a long piece of cloth. In order to ensure the processing quality of the umbrella cloth, the long piece of cloth needs to be edged and cut before it is made into an umbrella cloth. In these processes, strip-shaped edge materials are often produced at the edges of both sides of the cloth, which need to be collected by a trimming mechanism. The structure of the current trimming mechanism is relatively simple, such as the edge material collection device described in patent CN202020925798.1, which only sets a material roller to adapt to the material feeding speed of the cloth cutting machine for rotating and collecting the material. The applicant found that this structure is uncontrollable in the actual use of the coiled material position, and is easily affected by the change in the tension of the strip edge material, which is specifically reflected in the easy occurrence of entanglement and knotting, and when the tension is relatively stable, it is easy to be over-concentrated, resulting in frequent manual material guiding or replacement of the material roller.

[0004] Therefore, a new edge trimming mechanism is urgently needed to solve the problem of poor material trimming effect. Utility Model Content

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the utility model clearer, a detailed description is given below in conjunction with the accompanying drawings and specific implementation methods. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model. Therefore, the utility model is not limited by the specific implementation disclosed below.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to an element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0027] See also Figures 1 to 6 As shown, this embodiment discloses an automatic edge winding machine, including a frame 1, which mainly plays a bearing and supporting role. The frame 1 is welded by a plurality of metal profile components (H-shaped steel and C-shaped steel), and its bottom can be directly matched with the ground locking bolts for fixed assembly, and can also be connected and combined with external equipment (cloth cutting machine, etc.) through the openings on the frame 1.

[0028] The frame 1 is movably connected with a material roller 2, which can rotate relative to the frame 1 and serves as a winding device for the strip edge material. In this embodiment, the material roller 2 includes a rotating shaft 21 pivotally connected to the frame 1, and three T-shaped sets 22 are sleeved on the rotating shaft 21. Figure 5 and Figure 6 As shown, two T-shaped kits 22 are arranged opposite to each other to form an "H"-shaped edge material collecting roller structure, and the other T-shaped kit 22 and the outer side wall of the adjacent T-shaped kit 22 form a second material cavity, which can be used to separate and collect materials and synchronously reel in two types of edge materials. The specific usage method can be flexibly selected according to actual needs.

[0029] Furthermore, the axial inner end of the rotating shaft 21 is connected to the frame 1 through the bearing seat 3, and the rotating shaft 21 is vertically arranged with the side wall of the frame 1 and is in a horizontal state. The axial outer end of the rotating shaft 21 is a free end, and the free end area is provided with an external thread structure, which can form a meshing connection structure with a nut. The nut is locked at the outer end of the T-shaped kit 22 through the threaded connection structure with the rotating shaft 21 to form a limit locking structure ( Figure 6 Middle lock nut not shown).

The flange body 23 is a truncated cone structure, and its outer end forms a reduced diameter structure. This structure forms a "V"-shaped sinking groove structure at the center position of the "H"-shaped edge material collection roller structure, which is conducive to guiding the material during the winding process, so that the edge material is preferentially moved to the center position on the flange body 23, further improving the winding effect.

[0031] The material roller 2 is connected to a transmission member 4, and the transmission member 4 is used to connect the driving member to drive the material roller 2 to rotate. Specifically, the transmission member 4 includes a belt and a pulley, and the belt is connected between the rotating shaft 21 and the pulley. The pulley is connected to a tensioning adjustment member 5, and the tensioning adjustment member 5 can adjust the assembly position of the pulley. In this embodiment, the pulley is connected to the output end of the external motor, so the figure shows the driving member structure. In other embodiments, an independent driving motor can also be directly configured on the frame 1.

[0032] Further, combined with Figure 4As shown, the tension adjustment member 5 includes an adjustment base 51 fixedly connected to the frame 1, an adjustment slider 52 is movably connected to the adjustment base 51, a linear guide structure is formed between the adjustment slider 52 and the adjustment base 51, and the adjustment slider 52 can slide linearly back and forth relative to the adjustment base 51.

When in use, the adjustment cylinder 54 can control the position of the adjustment slider 52, that is, it can adjust the position of the pulley, thereby controlling the tension of the belt, so that the transmission structure is in a suitable working state.

[0033] The frame 1 is also provided with a material guide 6, and the material guide 6 is connected to a material guide structure capable of axially reciprocating parallel to the central rotation axis 21 of the material roller 2. Figure 3 As shown, the material guide member 6 includes a material guide frame 61 fixed on the frame 1, and a material guide slider 62 is provided on the material guide frame 61, and the bottom of the material guide slider 62 is used to be detachably connected to the material guide structure. In this embodiment, a linear module is provided at the bottom of the material guide frame 61, and the material guide slider 62 is arranged on the linear module. The material guide structure includes an extension rod 63 and a guide ring 64, and the stroke of the guide ring 64 corresponds to the winding area of ​​the material roller 2. In other embodiments, the driving structure of the material guide slider 62 can also adopt a screw motor combination structure, a cylinder, a hydraulic cylinder, etc.
