[0043] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.
[0044] Existing material-cutting devices use actuators such as cylinders, swing cylinders, and motors to drive the movement of the cutting component to achieve the cutting function. Typically, these actuators are made of cast iron or aluminum alloy, which meets the requirements of general industries and quantitative packaging equipment that does not require contact with materials. However, in some specialized industries, such as the lithium battery, pharmaceutical, and food industries, the control of material properties and foreign objects is extremely strict. In these cases, the actuator cannot be installed in the material channel and must be externally connected via complex mechanical mechanisms. This is extremely difficult to implement in confined material channels and cannot meet the protection requirements of these special industries.
[0045] To address the aforementioned issues, the applicant has developed a novel material-cutting component that effectively prevents material contamination and meets the requirements of quantitative packaging scenarios with stringent control over equipment materials and foreign matter.
[0046] Specifically, please refer to Figure 1 , Figure 1 This is a schematic diagram of one embodiment of the material cutting component of this application.
[0047] like Figure 1 The material cutting assembly 10 includes a material cutting member 100, and a through material channel 200 is formed inside the material cutting member 100. The material channel 200 is used to receive the material discharged from the outlet of the feeding system and guide the material into the packaging container.
[0048] In this embodiment, the material cutting component 100 is made entirely of flexible material. It can be driven by external force to deform in the direction pointing towards the center of the material channel 200 or away from the center of the material channel 200, thereby realizing the opening and closing of the material channel 200 and the adjustment of the channel opening, thus achieving the purpose of cutting material and controlling the feeding speed, and ensuring packaging accuracy.
[0049] Specifically, in this embodiment, the material cutting component 100 is controlled by fluid pressure, and the material cutting assembly 10 also includes a cylinder 300 sleeved outside the material cutting component 100. A fluid cavity 400 covering the outer wall of the material cutting component 100 is formed between the cylinder 300 and the material cutting component 100. At the same time, the cylinder 300 is also provided with a fluid port 304 communicating with the fluid cavity 400.
[0050] Understandably, by introducing fluid into the fluid cavity 400 through the fluid port 304 and extracting fluid from the fluid cavity 400, the fluid pressure inside the fluid cavity 400 can be controlled, thereby achieving the purpose of precisely controlling the deformation of the cutting component 100, and thus precisely controlling the opening and closing of the material channel 200 and the channel opening degree.
[0051] In one embodiment, gas can be introduced into the fluid cavity 400 to control the deformation of the cutting component 100 by air pressure. In another embodiment, liquid can be introduced into the fluid cavity 400 to control the deformation of the cutting component 100 by hydraulic pressure. Both embodiments can achieve the effect of this embodiment.
[0052] In addition, the material of the cutting part 100 in this application can be any flexible material that meets the contact requirements and elastic strength requirements of the packaging material, such as polyurethane elastomer, carbon fiber composite material, acrylic elastomer material, etc. It can be selected based on actual needs, and all of them can achieve the effect of this embodiment. It will not be elaborated here.
[0053] The following details the installation structure of the cutting component 100 and the cylinder 300 in this embodiment, such as... Figure 1 As shown, in this embodiment, the material cutting component 10 also includes an end cap 500, which is provided on the axial end of the cylinder 300, and the end cap 500 is provided with an opening 501 that matches the material channel 200. The end cap 500 and the cylinder 300 cooperate to clamp the material cutting component 100.
[0054] For further details, please refer to Figure 2 , Figure 2 yes Figure 1A magnified view of part A in the diagram.
[0055] like Figure 2 As shown, a first clamping surface 301 is arranged on the inner annular surface of the axial end of the cylinder 300, and a second clamping surface 502 is arranged on the outer annular surface of the end cap 500 facing the material channel 200. The first clamping surface 301 and the second clamping surface 502 cooperate to clamp the cutting component 100. Furthermore, in order to ensure the clamping stability of the cutting component 100, in this embodiment, the first clamping surface 301 or the second clamping surface 502 is a toothed surface with uneven surfaces. In order to improve the clamping stability of the cutting component 100 and at the same time improve the airtightness of the fluid cavity 400, in this embodiment, the first clamping surface 301 or the second clamping surface 502 is a frustum-shaped cone with the cone angle pointing towards the center of the material channel 200.
[0056] Specifically, in order to ensure that the fluid cavity 400 has a sufficient size and to provide sufficient deformation space for the cutting member 100, in this embodiment, the cylinder 300 includes a first extension section 302 extending along its axial direction and a second extension section 303 arranged at the end of the first extension section 302 and extending radially. The first extension section 302, the second extension section 303 and the cutting member 100 surround and form the fluid cavity 400.
[0057] Based on the material cutting component 10 of this embodiment, fluid can be introduced into or extracted from the fluid cavity 400 through the fluid port 304, thereby precisely controlling the deformation of the material cutting component 100 and achieving the purpose of controlling the opening and closing of the material channel 200 and the channel opening degree. Please refer to [link to relevant documentation]. Figure 3 , Figure 3 This is a schematic diagram of the working state of one embodiment of the material cutting component of this application. In the figure, a is a schematic diagram of the working state under normal pressure, b is a schematic diagram of the working state under low pressure, and c is a schematic diagram of the working state under high pressure.
[0058] like Figure 3 As shown, when the fluid chamber 400 is under normal pressure, the material channel 200 remains fully open; when the pressure inside the fluid chamber 400 is increased, the material-cutting component 100 deforms in the direction pointing towards the center of the material channel 200, thereby reducing the opening of the material channel 200, at which point the channel is half open; when the pressure inside the fluid chamber 400 is further increased, the material-cutting component 100 deforms to the position of completely closing the material channel 200, at which point the channel is fully closed, thus achieving material cutting.
[0059] Understandably, in actual packaging scenarios, the opening of the material channel 200 can be adjusted based on the target packaging weight. For example, when the real-time weight of the packaging container approaches the target packaging weight, the opening of the material channel 200 can be reduced by driving the cutting component 100 to deform until the target packaging weight is reached, thus completing the cutting and effectively ensuring packaging accuracy. After completing one batch of material packaging, the pressure inside the fluid chamber 400 can be quickly adjusted to atmospheric pressure, causing the cutting component 100 to reset and allowing the next batch of material packaging to proceed, ensuring the material packaging speed.
[0060] In particular, the opening of the material channel 200 in this application can be linearly varied with the degree of deformation of the cutting component 100. By controlling the pressure inside the fluid cavity 400, the opening of the material channel 200 can be steplessly adjusted, which is significantly better than conventional cutting devices and helps to improve packaging accuracy.
[0061] In addition, Figure 3 In the embodiment shown, the opening of the material channel 200 is reduced by increasing the pressure inside the fluid cavity 400 to drive the cutting member 100 to deform in the direction pointing towards the center of the material channel 200. In other embodiments, the fluid cavity 400 can also be made to have a negative pressure, thereby driving the cutting member 100 to deform in the direction away from the center of the material channel 200 to increase the opening of the material channel 200.
[0062] In the above embodiments, the cutting component 100 is clamped by the end cap 500 and the cylinder 300. In other embodiments, the cutting component 100 and the cylinder 300 can also be fixed in other ways. For example, the two ends of the cutting component 100 can be directly glued and fixed to the end of the cylinder 300, or the two ends of the cylinder 300 can be provided with slots that match the cutting component 100, and the cutting component 100 can be inserted into the slots for fixation, etc., which can also achieve the effect of this embodiment.
[0063] In the above embodiments, the entire cutting member 100 is made of a deformable flexible material. In other embodiments, only a portion of the cutting member 100 may be a deformable flexible part 101, which can also achieve the effect of this embodiment. Please refer to [link to relevant documentation]. Figure 4 , Figure 4 This is a schematic diagram of another embodiment of the material cutting component of this application.
[0064] like Figure 4 As shown, only one annular segment in the middle of the material cutting member 100 is a deformable flexible part 101, while the other parts are rigid parts 102. By synchronously deforming all parts of the annular flexible part 101, the purpose of cutting material and adjusting the channel opening can also be achieved. It can be understood that in other embodiments, the material cutting member 100 may also include multiple annular flexible parts 101 in the extension direction of the material channel 200, which can also achieve the effect of this embodiment.
[0065] In other embodiments, the material cutting member 100 may also include a plurality of non-annular flexible parts 101 that are isolated from each other. For example, it may include two flexible parts 101 arranged opposite to each other on both sides of the material channel 200. The two flexible parts 101 cooperate to achieve the purpose of controlling the opening and closing of the material channel 200 and adjusting the channel opening. As long as the effect of this embodiment can be achieved, the effect of this embodiment can be achieved, and it will not be described in detail here.
[0066] Based on the above embodiments, the material cutting component 10 can accurately control the opening of the material channel 200 through a minimalist structural design, ensuring packaging accuracy. It effectively solves the problem of needing an external driver with a complex mechanical structure in material packaging scenarios in special industries, effectively avoids the problem of material contamination, and can meet the quantitative packaging scenario requirements with very strict control over equipment materials and foreign objects.
[0067] This application also provides a material cutting control system 1 employing the above-described material cutting component 10. Please refer to [link to relevant documentation]. Figure 5 , Figure 5 This is a schematic diagram of one embodiment of the material cutting control system of this application.
[0068] like Figure 5 As shown, the material cutting control system 1 includes a material cutting component 10, a control mechanism 20, a fluid source 30, and a fluid suction mechanism 40 according to any of the above embodiments.
[0069] The fluid source 30 and the fluid suction mechanism 40 are connected to the fluid port 304 of the material interception assembly 10 through the first passage 50 and the second passage 60, respectively. The fluid source 30 is used to introduce fluid into the fluid cavity 400 to drive the flexible part 101 to deform in the direction pointing towards the center of the material channel 200. The fluid suction mechanism 40 is used to extract the fluid from the fluid cavity 400 to drive the flexible part 101 to deform in the direction away from the center of the material channel 200.
[0070] The control mechanism 20 is used to control the opening and closing of the first passage 50 and the second passage 60, thereby achieving the purpose of controlling the feeding speed and material cutting.
[0071] In one embodiment, the material cutting assembly 10 can be driven by air pressure, the fluid source 30 can be an air source, and the fluid suction mechanism 40 can be a vacuum generator.
[0072] This application also provides a quantitative packaging device; please refer to [link / reference]. Figure 6 , Figure 6 This is a schematic diagram of one embodiment of the quantitative packaging equipment of this application.
[0073] like Figure 6As shown, the quantitative packaging equipment includes a material cutting control system 1 and a weighing system 2 according to any of the above embodiments.
[0074] The material-cutting component 10 is arranged at the outlet of the feeding system 3 so that the material can enter the packaging container 4 through the material channel 200. The weighing system 2 is used to weigh the packaging container 4 in real time and feed the weight back to the material-cutting control system 1.
[0075] Specifically, the weighing system 2 may include a weighing sensor 21, which can feed back the real-time weight to the control mechanism 20 of the material cutting control system 1. The control mechanism 20 can calculate the target pressure of the current fluid cavity based on the real-time weight and the target weight, and adjust the pressure of the fluid cavity to the target pressure by controlling the operation of the fluid source 30 and the fluid suction mechanism 40, thereby realizing the control of the material cutting or feeding speed.
