Description

Technical Field

[0001] This application relates to the field of plant product processing technology, and in particular to a shaping device for thin plant sheet or filament materials. Background Technology

[0002] When shaping thin plant flakes or filaments less than 1mm thick, the material is brittle and easily broken, making it difficult to shape. Generally, workers need to bake the material by hand before manually bending and shaping it. During this manual bending and shaping, tools such as clamps and metal rods are used for assistance in shaping and positioning. Workers must rely on experience to frequently apply force at specific points on the plant flakes or filaments to bend them into the desired shape. This method is not only inefficient, with low yield and low quality, but also requires a very high level of skill from the workers. Especially when bending thin plant flakes into small-radius curls or multiple loops, the skill required is extremely high. Furthermore, manually bending thin plant flakes or filaments inevitably involves frequent contact between the hands and the sharp edges of the flakes or filaments, as well as frequent concentrated force applied to the tools and materials. These factors cause significant damage to the hands, and over time, can easily lead to occupational diseases such as finger deformities and skin abrasions. To address the shortcomings of existing technologies in manually shaping thin plant flakes or filaments less than 1 mm thick, such as low work efficiency, risk of hand injury, low yield and quality, and high skill requirements for workers, this application proposes a machine processing equipment to assist in the processing.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0020] like Figures 1-5 As shown, this application provides a plant thin-film shaping device, including a shape reference 1 and a presser 2, which are respectively mounted on a support surface 4 via end shafts 3 at their respective ends; At least one of the shape reference device 1 and the presser 2 is connected to a drive device; Presser 2 is used to apply pressure to the plant thin material 7 after it is placed on the shape reference 1 and the drive device is started, so that the plant thin material 7 gradually adheres to the surface of the shape reference 1.

[0021] In this embodiment, the shape reference 1 and the presser 2 can be mounted on a single equipment frame via their end shafts 3, or they can be mounted on different equipment frames via their end shafts 3, as long as they can provide stable support during use. The shape reference 1 and the presser 2 can both be connected to a driving device, or either the shape reference 1 or the presser 2 can be connected to a driving device. In actual production, the driving device can be a motor 5, a cylinder 6, or an electric cylinder. If the driving device is a motor 5, the relative rotation of the shape reference 1 and the presser 2 will cause the surface of the plant thin material 7 to be processed to be gradually pressed against the surface of the shape reference 1 by the presser 2, thus achieving a shaping effect. If the driving device is an electric cylinder or a cylinder 6, the relative distance between the shape reference 1 and the presser 2 will be changed, causing the surface of the plant thin material 7 to be processed to be gradually pressed against the surface of the shape reference 1 by the presser 2, thus achieving a shaping effect. The shaping equipment of this application is particularly suitable for shaping thin sheet or filamentous plant materials (such as bamboo products) with a thickness of less than 1 mm. It should be noted that after the drive device is started, there is a gap between the shape reference 1 and the presser 2 to ensure that the thin plant material can be placed into the gap between the shape reference 1 and the presser 2 for shaping. Furthermore, a certain gap will still exist between the shape reference 1 and the presser 2 when the pressure is reached at its limit.

[0022] Compared to the traditional method of manually shaping plant veneer 7, the veneer shaping equipment of this application not only improves the shaping efficiency of plant veneer 7 but also reduces the risk of hand injury to workers during the processing. Furthermore, in this application, the final shape of plant veneer 7 is primarily determined by the surface shape of the shape reference device 1 during processing. This reduces the need for workers' personal experience and effectively ensures the yield and quality of the finished products.

[0023] In one possible implementation, such as Figure 1 As shown, the cross-sections at different positions of the shape reference 1 present different shapes or patterns.

[0024] In this embodiment, the shape setting of the shape reference 1 is determined based on the final shaping requirements of the plant thin film 7. For example... Figure 8 and Figure 9 As shown, in actual production, the cross-section of the shape reference 1 can be circular, elliptical, or even irregular. When different shaping requirements are needed for some plant thin sheets 7 at different locations, the cross-sections of the shape reference 1 at different locations can be set to different shapes or graphics, which can improve the flexibility of processing the plant thin sheets 7.

[0025] In another possible implementation, such as Figure 6 and Figure 7 As shown, shape reference 1 is conical, or shape reference 1 is cylindrical.

[0026] In this embodiment, the common plant thin material 7 is mostly rolled into a regular shape during production and processing. Setting the shape reference 1 of this application to a conical or cylindrical shape can not only be applicable to most plant thin material 7 production and processing scenarios, but also reduce the processing difficulty and processing cost when making the shape reference 1.

[0027] Optional, such as Figure 6 and Figure 7 As shown, the presser 2 is cylindrical.

[0028] In this embodiment, the main function of the presser 2 is to apply a uniform force to the plant thin material 7, causing it to bend on the surface of the shape reference 1. By setting the presser 2 to a cylindrical shape, it can produce a uniform pressure effect on the surface of the plant thin material 7 regardless of whether it rotates or moves relative to the shape reference 1.

[0029] In some embodiments, the shape reference 1 and / or the presser 2 are made of silicone.

[0030] In this embodiment, the shape reference 1 and / or the presser 2 of this application are made of silicone material because, compared with traditional metal materials, the elasticity of silicone can protect the integrity of bamboo fiber and reduce the risk of texture wear or breakage of the plant thin material 7 due to rigid contact during the processing.

[0031] In some embodiments, at least one of the shape reference 1 and the presser 2 is provided with a heating device.

[0032] In this embodiment, the plant thin material 7 can be heated to the target temperature by a heating device during processing, so that when pressing, it can assist in shaping some brittle materials at room temperature.

[0033] In some embodiments, the heating device is a resistance wire disposed within the shape reference 1 or the presser 2.

[0034] In this embodiment, the shape reference 1 or the presser 2 of this application has a cavity inside, which can be used to place a heating wire with heating capability. After being energized, the heating wire can heat the shape reference 1 or the presser 2 from the inside, so that it can act on the plant thin material 7 during the processing of the plant thin material 7. Generally, the temperature of the shape reference 1 or the presser 2 after being heated by the heating wire reaches 150~350 degrees Celsius, which is sufficient to meet the deformation requirements of the plant thin material 7. However, the specific parameters depend on the actual thickness of the material to be processed, the temperature and humidity of the processing environment. The thicker the material to be processed, the lower the temperature of the processing environment, and the higher the humidity, the higher the target temperature needs to be. In order to avoid the material of the shape reference 1 or the presser 2 from softening or deforming during the high-temperature heating process, the material of the shape reference 1 and the presser 2 of this application can be a high-temperature resistant material, such as high-temperature resistant silicone.

[0035] In some embodiments, the heating device is an electromagnetic induction coil wound around the shape reference 1 or the presser 2, and the shape reference 1 or the presser 2 is made of a conductive material.

[0036] In this embodiment, when the shape reference 1 or the presser 2 of this application is heated using the principle of electromagnetic induction, the shape reference 1 and the presser 2 should be made of conductive materials, such as iron alloy.

[0037] Optionally, the electromagnetic induction coil is wound around the end away from the shape reference 1 or the presser 2 that is in contact with the plant material 7, so as to avoid interference from the electromagnetic induction coil during the shaping process of the plant material 7.

[0038] Optionally, regardless of whether an electromagnetic induction coil or a resistance wire is used for heating, when processing bamboo sheet or filament materials of 0.1-0.2mm thickness, for example, at 20-25℃ and humidity around 70%, the target temperature should be set to 180℃. Alternatively, during the plum rain season or the yellow plum season, when humidity increases to 90% or higher, the temperature needs to be increased to 200-210℃.

[0039] In some embodiments, such as Figure 1 and Figure 2 As shown, the end shaft 3 is a cylindrical support member. Both ends of the shape reference device 1 or the presser 2 are fixedly installed with an end shaft 3. The end shaft 3 is installed on the side plate of the equipment housing and is used to provide support force for the shape reference device 1 or the presser 2.

[0040] In this embodiment, the shape reference 1 or the presser 2 of this application should be installed at a certain height to facilitate worker operation. Therefore, a matching equipment housing can be fabricated according to the actual site environment. The shape reference 1 and the presser 2 are mounted on the side plates of the corresponding positions of the equipment housing through cylindrical support members at their respective ends. In this way, the equipment housing can support the shape reference 1 and the presser 2 at a certain distance from the ground, so that the worker can place the plant veneer 7 to be processed on the shape reference 1 for shaping. To provide installation stability, the shape reference 1 and the presser 2 are mounted on the two side plates of the corresponding positions of the equipment housing through cylindrical support members at their respective two ends, so that both ends of the shape reference 1 and the presser 2 are installed between the opposite side plates of the equipment housing.

[0041] In some embodiments, such as Figure 1 As shown, the driving device is a motor 5, and the output shaft of the motor 5 is connected to one end shaft 3 of the shape reference device 1 or the presser 2 via a belt drive or chain drive.

[0042] In this embodiment, if the driving device of this application is a motor 5, the output shaft of the motor 5 can be connected to one end shaft 3 of the shape reference 1 or the presser 2 via belt drive or chain drive. Alternatively, one end shaft 3 of the shape reference 1 or the presser 2 can be directly connected to the output shaft of the motor 5. For ease of understanding, this is further explained by taking the connection between one end shaft 3 of the presser 2 and the output shaft of the motor 5 via a transmission belt. Because the motor 5 needs to drive the presser 2 to rotate around its own axis via the transmission belt after starting, the two end shafts 3 of the presser 2 and the device housing should be rotatably connected during installation. However, the shape reference 1 does not need to rotate at this time, and its end shaft 3 can be fixedly connected to the device housing during assembly. Figure 3As shown, during the counterclockwise rotation of the presser 2, a compressive force is generated on the plant material 7 placed on the upper side of the shape reference 1. This compressive force is along the tangential direction of the presser 2. When this force acts on the plant material 7 on the shape reference 1, it generates downward pressure, thereby completing the shaping effect by adhering the plant material 7 to the surface of the shape reference 1. The final processing effect is as follows. Figure 5 As shown. If the output shaft of motor 5 is connected to one end of shaft 3 on shape reference 1 via a transmission belt, its operating principle is similar to that of motor 5 and presser 2, which will not be elaborated here. The main difference is that the rotation direction of shape reference 1 is related to the rotation direction of presser 2. The working diagram is shown below. Figure 4 As shown.

[0043] In some embodiments, such as Figure 2 As shown, the driving device is a pneumatic cylinder 6 or an electric cylinder. The output end of the pneumatic cylinder 6 or the electric cylinder is connected to the shape reference device 1 or the presser 2. The gap width between the shape reference device 1 and the presser 2 can be changed by the pneumatic cylinder 6 or the electric cylinder.

[0044] In this embodiment, when the driving device of this application is a cylinder 6 or an electric cylinder, their working principles are similar regardless of whether they are connected to a shape reference device 1 or a presser 2. Therefore, only the connection between the cylinder 6 and the presser 2 is used as an example for illustration. The working principles of other possible methods can be referred to the working principle of the connection between the cylinder 6 and the presser 2.

[0045] If the presser 2 and the cylinder 6 are connected, the cylinder 6 is mounted on the equipment housing by a bracket and located outside the housing. The output shaft of the cylinder 6 is connected to the end shaft 3 of the presser 2. After the cylinder 6 is started, its output end needs to push the presser 2 toward the shape reference 1. This requires that a keyway facing the shape reference 1 be opened on the side wall of the equipment housing used to install the end shaft 3 of the presser 2. The length of the keyway meets the requirement of the maximum displacement of the presser 2. The shape reference device 1 primarily provides support for the plant veneer 7 to be processed. Therefore, the end shaft 3 of the shape reference device 1 can be fixedly connected to the equipment housing. After the worker places the plant veneer 7 between the shape reference device 1 and the presser 2, the cylinder 6 is activated. The cylinder 6 pushes the presser 2 closer to the shape reference device 1. During this process, the gap between the shape reference device 1 and the presser 2 continuously decreases, and the pressure applied by the presser 2 to the plant veneer 7 pushes it to bend towards the surface of the shape reference device 1. As the plant veneer 7 adheres to the surface of the shape reference device 1, the external contour of the plant veneer 7 is shaped by the shape reference device 1. This process is completed by mechanical equipment, and the degree of shaping of the plant veneer 7 can be adjusted by controlling the extension and retraction of the cylinder 6. It is not only simple and labor-saving to use, but also provides good controllability of the shaping effect.

[0046] In actual production, to ensure the stability of the presser 2 driven by the cylinder 6 during movement, a cylinder 6 can be installed at each end shaft 3 of the presser 2. The output end of the cylinder 6 is sleeved on the end shaft 3 of the presser 2. The two cylinders move synchronously during use, which can make the presser 2 bear force evenly, thereby increasing the stability of the presser 2 during movement. Alternatively, one end shaft 3 of the presser 2 can be connected to the cylinder 6, and the other end shaft 3 can be connected to the telescopic rod. During the process of the cylinder 6 driving the presser 2 through one end shaft 3, the telescopic rod can guide the other end shaft 3 of the presser 2, thereby assisting the cylinder 6 in enabling the presser 2 to move smoothly towards the shape reference device 1.

[0047] In some embodiments, the presser 2 and the shape reference 1 may also be connected to the cylinder 6 and the motor 5, respectively.

[0048] In this embodiment, the shape reference device 1 connected to it is driven by the motor 5 to rotate, which, in conjunction with the presser 2, achieves the shaping effect of the plant veneer 7. The presser 2 connected to it is driven by the cylinder 6 (or electric cylinder) to adjust the gap between the presser 2 and the shape reference device 1. Thus, in production, the device of this application can be applied to plant veneers 7 of various thicknesses. In addition, the same effect can be achieved by connecting the presser 2 to the motor 5 and the shape reference device 1 to the cylinder 6.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
