Description

Technical Field

[0001] This utility model relates to the field of umbrella processing equipment, and in particular to an automatic wood ear flower making machine. Background Technology

[0002] An umbrella is a tool for providing shade or protection from rain and snow, and is generally made of oiled paper, oilcloth, or plastic sheeting.

[0003] The main components of an umbrella include the handle, center rod, ribs, fabric, straps, beaded tail, cap, and decorative trim. The decorative trim is placed under the cap to fill the gap between the umbrella fabric and the cap; it is currently made of plastic, fabric, or other materials.

[0004] For example, patent CN104652046B discloses an automatic processing equipment for wood ear flowers, including a feeding device, a folding and clamping device, and a cutting device. The cutting device is located between the feeding device and the folding and clamping device. The feeding device includes a feeding guide rail and a push rod. The folding and clamping device includes an upper clamping plate and a lower clamping plate, both with arc-shaped front ends. The upper clamping plate can rotate up and down, and the upper surface of the guide rail is located in the middle of the upper clamping plate. The push rod pushes the fabric forward. The fabric in front of the push rod is lifted up by the action of the upper clamping plate, and the fabric behind the push rod enters the gap between the upper and lower clamping plates. The folding and clamping device can also be moved back and forth to below the sewing machine needle.

[0005] In the above technical solution, the folded material is first cut into a fixed length, and then folded and sewn together with a sewing machine. The whole process requires the use of a feeding device, a folding clamping device, a cutting device and a sewing machine. The structure is complex, the failure rate of the processing parts between the components is relatively high, and the thread sewing not only damages the sealing of the wood ear flower, but also easily loosens, leading to the destruction of the wood ear flower structure. Utility Model Content

[0006] This utility model provides an automatic wood ear flower processing machine, which helps to solve the problems of complex structure, high failure rate of connection between processing parts in some current wood ear flower processing equipment, and the fact that wire sewing will affect the sealing and structural stability of the wood ear flower.

[0007] This utility model is implemented as follows: An automatic wood ear flower making machine includes a frame, a worktable on top of the frame, a fixture base on the worktable, and a material trough with a top opening on the fixture base. The material trough is used to hold round wood ear flower processing materials. A pressing die that can be vertically inserted into the material trough is located at the top of the material trough. The pressing die is connected to a transverse drive component and a lifting drive component. The pressing die can extrude and shape the wood ear flower processing materials in the material trough. Several shaping holes are arranged symmetrically on the inner wall of the material trough. The shaping holes transversely penetrate the fixture base. A shaping rod is movably installed in the shaping holes. The outer end of the shaping rod away from the material trough is connected to a centering clamping mechanism. Each shaping rod can move radially inward synchronously to press and shape the outer periphery of the wood ear flower processing materials after pressing and shaping in the material trough, resulting in a double-layered folded material with wrinkled outer periphery. A receiving module that can be lifted and moved is located at the top of the material trough. The receiving module has a lifting punch that can be lifted and moved. After the pressing die moves out of the material trough, the punch can extend into the material trough to perform heat-melt bonding at the threshold position of the double-layered folded material.

[0008] Based on the above technical solution, the top of the workbench has a horizontal end face, and the tooling seat is embedded in the center of the workbench, with the top end face of the tooling seat flush with the top end face of the workbench.

[0009] Based on the above technical solution, the outer lateral periphery of the mold is provided with a serrated structure.

[0010] Based on the above technical solution, the centering clamping mechanism includes a limiting rod fixedly connected to the outer end of the shaping rod. A connecting rod is hinged to the bottom of the limiting rod, and a drive frame is hinged to the bottom of the connecting rod. The drive frame is connected to a shaping cylinder. The main body of the shaping cylinder is fixed to the bottom of the tooling base. The shaping cylinder can control the longitudinal movement of the drive frame. When the drive frame moves downward, it can synchronously drive each connecting rod to swing in the threshold direction, thereby controlling each shaping rod to slide towards the material groove side. The shaping rod and the shaping hole form a transverse guide structure.

[0011] Based on the above technical solution, the tooling base is provided with a track groove at the bottom of the outer end of each shaping hole. The track groove is used to constrain the movement path of the limiting rod. Each track groove and the shaping hole corresponding to its top work together to form an inverted "L" shaped cavity.

[0012] Based on the above technical solution, the shaping rod has a rounded corner structure at the end near the material trough.

[0013] Based on the above technical solution, the top of the mold is connected to an installation rod, the installation rod is connected to a lifting cylinder, the main body of the lifting cylinder is fixed on a transverse support, the transverse support is connected to a transverse cylinder, the main body of the transverse cylinder is fixed on a mounting frame, and the bottom of the mounting frame is connected to the machine frame; the transverse cylinder can drive the transverse support to reciprocate transversely in the front and rear directions of the material trough, and the lifting cylinder can drive the installation rod and the mold to move up and down.

[0014] Based on the above technical solution, the receiving module includes an ultrasonic welding mechanism, which includes an ultrasonic generator, a transducer, an amplitude transformer, and a welding head, with the welding head fixedly connected to the punch.

[0015] Based on the above technical solution, the front side of the frame is provided with a slide rail for finished product output.

[0016] Compared with the prior art, the present invention has at least the following advantages: This invention simplifies the equipment structure. Compared with the prior art, it reduces complex components such as feeding devices and cutting devices. The processing of wood ear flowers can be completed through the coordinated work of key components such as tooling base, pressing mold, shaping rod, and receiving module, which greatly simplifies the equipment structure and reduces equipment costs and maintenance difficulty.

[0017] Due to the simplified equipment structure, during operation, the operator places the wood ear flower processing material into the material trough. Subsequently, the wood ear flower processing material remains in the material trough throughout the forming process, avoiding the need for processing parts to be transferred between components. This reduces the failure rate of processing parts between components, improves the reliability and stability of the equipment, and reduces production interruptions and maintenance costs caused by equipment failures.

[0018] The use of hot-melt bonding technology instead of sewing machine stitching avoids damaging the seal of the wood ear flower with sewing thread, effectively preventing water ingress or moisture damage during use. At the same time, the ultrasonic welding creates a stronger bond that is less prone to loosening, ensuring the structural stability of the wood ear flower and improving the overall quality of the umbrella.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0023] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the element or there may be an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0026] Example 1: Combination Figures 1 to 5This embodiment discloses an automatic wood ear flower processing machine to solve the problems of complex structure, high failure rate, and the impact of threaded stitching on the sealing and structural stability of existing wood ear flower processing equipment. This automatic wood ear flower processing machine simplifies the processing flow, reduces equipment failure rate, and improves the sealing and structural stability of the wood ear flowers.

[0027] The automatic wood ear flower machine specifically includes a frame 1, which serves as the supporting structure for the entire equipment, providing a foundation for the installation of other components and ensuring the stability of the equipment during operation. The frame 1 is assembled from aluminum alloy profiles and plastic panels. The bottom of the frame 1 is equipped with support legs 11, which are height-adjustable support legs. This facilitates the leveling and fine-tuning of the installation height after the equipment is installed, ensuring the normal operation of all components.

[0028] The top of the frame 1 is equipped with a worktable 2, which is a boss structure with a horizontal end face on its top, providing a flat surface for the installation of components such as the tooling seat 21, and also facilitating the operation of the operator.

[0029] The workbench 2 is equipped with a fixture base 21, which is embedded in the center of the workbench 2. The top end face of the fixture base 21 is flush with the top end face of the workbench 2 to ensure stability during processing. The fixture base 21 is equipped with a material groove 22 with a top opening structure. The material groove 22 is used to place round pieces of wood ear flower processing material (in this embodiment, the processing part is a round thin sheet of raw material made of materials such as cloth and plastic).

[0030] A plurality of shaping holes 23 are centrally symmetrically arranged on the inner wall of the material trough 22. The shaping holes 23 transversely penetrate the tooling base 21. A shaping rod 25 is movably arranged within the shaping holes 23. The shaping rod 25 can slide along the shaping holes 23, that is, the shaping rod 25 can slide relative to the material trough 22 within the shaping holes 23. In order to avoid damage to the structure of the wood ear flower processing material due to sharp structures, the end of the shaping rod 25 near the material trough 22 has a rounded corner structure. This allows the shaping rod 25 to safely and reliably hold the wood ear flower processing material after it moves inward, thereby improving the processing quality and yield.

[0031] A mounting bracket 4 is provided on the top of the frame 1, directly behind the material trough 22. The mounting bracket 4 is a vertical plate structure, and its bottom is connected and fixed to the worktable 2.

[0032] The mounting frame 4 is provided with a pressing mold 6 above the material trough 22. That is, the top of the material trough 22 is provided with a pressing mold 6 that can be vertically inserted into the material trough 22. The outer lateral periphery of the pressing mold 6 is provided with a sawtooth structure. The specific structure of the pressing mold 6 is similar to the structure of a gear. Its function is that after the pressing mold 6 presses down on the flat wood ear flower processing material, it can cause the center of the wood ear flower processing material, which was originally flat, to be concave and the surrounding area to bend upward and form a fold. This lays the foundation for subsequent shaping into the shape of wood ear flowers.

[0033] Furthermore, the pressing die 6 is connected to a transverse drive assembly and a lifting drive assembly, enabling the pressing die 6 to extrude and shape the wood ear flower processing material located in the material trough 22. Combined with... Figure 4 As shown, the top of the mold 6 is connected to a mounting rod 61, which is an L-shaped rod structure. The mounting rod 61 is connected to a lifting cylinder 62, the main body of which is fixed to a transverse support 63. The transverse support 63 is connected to a transverse cylinder 64, the main body of which is fixed to a mounting frame 4. The bottom of the mounting frame 4 is connected to the machine frame 1. The transverse cylinder 64 can drive the transverse support 63 to reciprocate transversely in the front-rear direction of the material trough 22, and the lifting cylinder 62 can drive the mounting rod 61 and the mold 6 to move up and down. This allows for precise control of the mold 6 and provides misalignment and anti-interference capabilities relative to the material trough 22, which helps to provide sufficient space for the operation of the receiving module 5.

[0034] Combination Figure 2 and Figure 3 As shown, the outer end of the shaping rod 25 away from the material trough 22 is connected to a centering clamping mechanism. Each shaping rod 25 can move radially inward synchronously to press and shape the outer periphery of the wood ear flower processing material after pressing and shaping in the material trough 22, resulting in a double-layer folded material with pleats on the outer periphery.

[0035] Furthermore, the centering and clamping mechanism includes a limiting rod 251 fixedly connected to the outer end of the shaping rod 25. A connecting rod 26 is hinged to the bottom of the limiting rod 251, and a drive frame 271 is hinged to the bottom of the connecting rod 26. The drive frame 271 is connected to a shaping cylinder 27. The main body of the shaping cylinder 27 is fixed to the bottom of the tooling base 21. The shaping cylinder 27 can control the longitudinal movement of the drive frame 271. When the drive frame 271 moves downward, it can synchronously drive each connecting rod 26 to swing in the threshold direction, thereby controlling each shaping rod 25 to slide towards the material groove 22. The shaping rod 25 and the shaping hole 23 form a transverse guide structure. The tooling base 21 is provided with a track groove 24 at the bottom of the outer end of each shaping hole 23. The track groove 24 is used to constrain the movement path of the limiting rod 251. Each track groove 24 and the shaping hole 23 corresponding to its top form an inverted "L" shaped chamber, further ensuring the stable operation of the centering and clamping mechanism. It should be noted that other centering and clamping mechanisms with different structures can be used in other embodiments, and the appropriate type can be flexibly selected from the existing technology according to actual production needs.

[0036] The top of the material trough 22 is equipped with a lifting and lowering receiving module 5. Specifically, the receiving module 5 is mounted on the mounting frame 4, and its top is connected to a stamping cylinder 52. The stamping cylinder 52 can control the up and down movement of the entire receiving module 5. The receiving module 5 is equipped with a lifting and lowering punch 51. After the pressing mold 6 moves out of the material trough 22, the punch 51 can extend into the material trough 22 to perform heat-melting bonding at the threshold position of the double-layer folded material. In this embodiment, the receiving module 5 includes an ultrasonic welding mechanism, which includes an ultrasonic generator, a transducer, an amplitude transformer, and a welding head. This is prior art, and its specific structure and working principle will not be described in detail here. Those skilled in the art can select and implement it from the prior art according to the actual operation.

[0037] In this embodiment, the welding head is fixedly connected to the punch 51, which allows the punch 51 to press down on the wood ear flower processing material and complete the hot melt bonding operation under controlled shape.

[0038] refer to Figure 5 , Figure 5 The longitudinal section diagram shows the morphological changes of the wood ear flower processing material during the processing. Initially, the wood ear flower processing material is placed in the material groove 22 in a flat sheet-like structure. After being pressed down by the pressure mold 6, its outer periphery bends upward, and the longitudinal section outline has a "U" shape. In this state, the outer periphery of the wood ear flower processing material also has a pleated structure. Then, the shaping rod 25 moves inward to press and hold it, causing the top of the outer periphery of the wood ear flower processing material to fold and compress inward, forming a double-layer stacked shape. Then, the punch 51 of the receiving module 5 moves down to press and shape the top center area, and heat-melt bond the upper stacked section with the original bottom section to obtain the finished wood ear flower.

[0039] To make material discharge more convenient, the front side of the frame 1 is provided with a slide rail 3 for finished product output. The top of the slide rail 3 is open, so that the operator can easily put the finished product into the slide rail 3 and let the finished product slide down along the slide rail 3 in a directional manner. The material box can be placed at the drop position for easy collection.

[0040] Example 2: Based on Example 1, combined with Figure 6 As shown, in order to make the operation safer, the workbench 2 is equipped with a sensor module 7, which is a photoelectric sensor. Its detection position is located above the material trough 22 and is used to detect the top area of ​​the material trough 22. For example, if the operator's limbs are in the threshold area, a safety alarm signal is triggered. In this state, the punch 51 cannot move down to work, thereby improving the safety of the operation.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
