Description
Technical Field
[0001] This utility model belongs to the technical field of cutting beds, and relates to a partitioned air suction duct component for a cutting bed. Background Technology
[0002] The cutting table is usually equipped with an air extraction hole for vacuum extraction, which firmly adheres the material laid on the worktable to the worktable surface, preventing the material from shifting during cutting, thus affecting the accuracy of the cutting size and the pattern of the garment.
[0003] To accommodate more cutting needs, extra-long models such as 6 meters, 9 meters, 15 meters, and 18 meters have emerged. Due to the excessive length of the bed, existing suction equipment cannot generate sufficient suction, affecting the cutting effect.
[0004] Chinese utility model patent CN215613740U (publication date: 2022.01.25) discloses a suction system for a cutting bed, including a partitioned suction structure and a vacuum suction plate. The vacuum suction plate and the partitioned suction structure are connected by a suction pipe. The suction pipe is connected to a suction device. The vacuum suction plate includes a perforated plate, a partitioned grid plate, and a base plate arranged sequentially from top to bottom. The perforated plate has multiple suction holes. It also includes a mounting frame fixed to the upper surface of the partitioned grid plate. The upper surface of the mounting frame abuts against the lower surface of the perforated plate. The upper surface of the mounting frame has several suction holes. The mounting frame is a hollow U-shaped channel steel. The U-shaped end of the mounting frame has a suction end. The suction end pipe of the mounting frame is connected to the suction device. The partitioned grid plate has ventilation pipes.
[0005] The aforementioned suction system uses zoned vacuum suction, which can reduce excess energy consumption, but its suction volume cannot be adjusted, making it unable to meet diverse needs. Utility Model Content
[0006] This invention addresses the shortcomings of existing technologies by providing a partitioned air suction duct component for a cutting bed. While generating sufficient air suction effect, it can also provide multiple air suction modes to meet diverse air suction needs.
[0007] To solve the above-mentioned technical problems, the objective of this utility model is achieved through the following technical solution:
[0008] A partitioned suction duct component for a cutting bed includes several mutually isolated segmented bed bodies equipped with suction inlets. The suction inlets are connected to a main suction duct via a partitioned suction control component. The partitioned suction control component is equipped with a control valve that controls the connection state of the partitions. A pump assembly is correspondingly arranged on the outer side of each segmented bed body. The pump assembly is also connected to the main suction duct. The control valve and the pump assembly control the switching of suction modes. The suction modes include a small suction mode that only activates some pump assemblies, a large suction mode that activates all pump assemblies, and a follow-up suction mode that activates the control valve as the cutting area changes.
[0009] In the aforementioned partitioned air suction duct component of a cutting bed, the partitioned air suction control component includes a partitioned air suction duct, one end of which is connected to the main air suction duct and the other end is connected to the air suction port of the segmented bed body. The control valve is installed inside the partitioned air suction duct and is driven by a power device.
[0010] In the aforementioned partitioned air intake duct component of a cutting bed, the control valve includes a valve stem and a valve disc. The valve stem is rotatably mounted on the partitioned air intake duct, and the valve disc is circular with a diameter that matches the inner diameter of the partitioned air intake duct. The power device drives the valve stem to rotate and causes the valve disc to rotate in order to control the connection state of the partitioned air intake duct. When the valve disc rotates to a position coaxial with the partitioned air intake duct, the valve disc cuts off the inner cavity of the partitioned air intake duct.
[0011] In the aforementioned partitioned suction duct component of a cutting bed, the power unit is a cylinder, the cylinder body of the cylinder is hinged to the partitioned suction duct, the piston rod of the cylinder is hinged to one end of a connecting rod, and the other end of the connecting rod is hinged to a valve rod; furthermore, a pin for connecting the cylinder is connected to the partitioned suction duct.
[0012] In the above-mentioned partitioned air suction duct component of a cutting bed, a pipe clamp is fitted on the partitioned air suction duct, the valve stem passes through the pipe clamp and the partitioned air suction duct, a bushing is provided between the valve stem, the pipe clamp, and the partitioned air suction duct, a retaining ring is fitted on the valve stem outside the pipe clamp, and a pair of bushings and retaining rings are provided.
[0013] In the partitioned air intake duct component of the cutting bed described above, the power unit can also use other mechanisms, such as an electric motor, which drives the valve stem to rotate via a gear set.
[0014] In the partitioned air intake duct component of the cutting bed described above, the control valve may also use other structures, such as a valve stem that is driven by a power unit to extend and retract, with a valve core connected to the valve stem to cut off the duct.
[0015] In the aforementioned partitioned air intake duct component of a cutting bed, the main air intake duct is composed of multiple pipe sections, with a T-joint between each pipe section. The pump assembly and the partitioned air intake control assembly are both connected to the main air intake duct via the T-joint.
[0016] In the aforementioned partitioned air intake duct component of a cutting bed, the length of the cutting bed body is 6-18 meters, and the bed body is divided into a segmented bed body every 3 meters.
[0017] Compared with the prior art, this utility model has the following advantages:
[0018] 1. This utility model provides a zoned suction duct component for a cutting bed, comprising a segmented bed body, zoned suction control components, and pump components to form a suction system. Multiple pump components concentrate the suction airflow into the main suction duct, while multiple zoned suction control components separately control the suction of multiple segmented bed areas, ensuring that the suction in each area reaches its maximum value. This utility model allows for switching suction modes via control valves and pump components, including a low suction mode with only some pump components activated, a high suction mode with all pump components activated, and a follow-up suction mode where the control valves activate according to changes in the cutting area. Through various combinations, it flexibly adsorbs fabrics of different difficulty and length, providing ample and flexible adsorption options for cutting ultra-long and difficult-to-adsorb fabrics; it solves the adsorption problem for cutting ultra-long fabrics while also saving customers' electricity.
[0019] 2. This utility model adopts a modular design. Each segmented bed corresponds to a main suction pipe segment, a zone suction control component, and a pump assembly. Each main suction pipe segment, zone suction control component, and pump assembly constitutes a modular unit. Combining multiple modular units forms the entire suction system. The pump assembly and zone suction control component can be added or removed modularly as the machine length changes, making it very convenient to use.
[0020] 3. This utility model also provides a zoned air intake control component, which controls the connection status of the pipeline by rotating a circular valve disc pulled by a cylinder. It has a simple structure, low cost, and low assembly precision requirements, making it particularly suitable for the modular installation method of this utility model. Attached Figure Description

[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-4 :
[0027] A partitioned suction duct component for a cutting bed includes several mutually isolated segmented bed bodies equipped with suction ports. The suction ports are connected to a main suction duct 2 via a partitioned suction control component 1. The partitioned suction control component 1 is equipped with a control valve 3 that controls the connection state of the partitions. A pump assembly 4 is correspondingly arranged on the outer side of each segmented bed body. The pump assembly 4 is also connected to the main suction duct 2. The control valve 3 and the pump assembly 4 control the switching of suction modes. The suction modes include a small suction mode that only activates a portion of the pump assembly 4, a large suction mode that activates all of the pump assembly 4, and a follow-up suction mode that activates the control valve 3 as the cutting area changes.
[0028] Comparison Appendix Figure 1 This embodiment shows an extra-long, special model measuring 18 meters. The entire bed is divided into six sections, with six pump assemblies 4 supplying air to the main suction duct 2. The main suction duct 2 further branches into six zone suction control assemblies 1, each controlling a specific cutting and adsorption area. For example, when cutting ordinary fabrics, all control valves 3 and pump assemblies 4 can be opened to adsorb the fabric, generating sufficient suction – this is the high suction mode. When cutting easily adsorbed fabrics, all control valves 3 and some pump assemblies 4 are opened, significantly saving power – this is the low suction mode. When cutting special, difficult-to-adsorb fabrics, only one valve is opened to adsorb the fabric. Then, as the cutting area changes, the six valves alternately open and close, always following the cutting area to maximize the adsorption force – this is the follow-up suction mode. This embodiment provides a new model that integrates simple and super-strong adsorption, short and extra-long cutting, especially addressing the pain point of cutting extra-long and difficult-to-adsorb fabrics.
[0029] Comparison Appendix Figure 2 The partitioned air intake control component 1 includes a partitioned air intake duct 5, one end of which is connected to the main air intake duct 2 and the other end is connected to the air intake of the segmented bed. The control valve 3 is installed inside the partitioned air intake duct 5 and is driven by a power device.
[0030] Comparison Appendix Figure 3 The control valve 3 includes a valve stem 6 and a valve disc 7. The valve stem 6 is rotatably mounted on the partitioned air intake duct 5. The valve disc 7 is circular, and its diameter is adapted to the inner diameter of the partitioned air intake duct 5. The power device drives the valve stem 6 to rotate and drives the valve disc 7 to rotate to control the connection state of the partitioned air intake duct 5. When the valve disc 7 rotates to a position coaxial with the partitioned air intake duct 5, the outer circumferential surface of the valve disc 7 is in contact with the inner wall of the partitioned air intake duct 5, and the valve disc 7 cuts off the inner cavity of the partitioned air intake duct 5. When the valve disc 7 rotates a certain angle from the coaxial position, the valve disc 7 is in an inclined state relative to the partitioned air intake duct 5, and a certain gap is formed between the outer circumferential surface of the valve disc 7 and the inner wall of the partitioned air intake duct 5, and the inner cavity of the partitioned air intake duct 5 is connected. Figure 4 The state shown.
[0031] Furthermore, the power device is a cylinder 8, the cylinder body of the cylinder 8 is hinged to the partitioned air intake pipe 5, the piston rod of the cylinder 8 is hinged to one end of the connecting rod 9, and the other end of the connecting rod 9 is hinged to the valve rod 6; furthermore, the partitioned air intake pipe 5 is connected to the hinged cylinder 8 pin; when the piston rod of the cylinder 8 extends or retracts, it pulls or pushes the valve rod 6 to rotate through the connecting rod 9, and at the same time the cylinder body and piston rod of the cylinder 8 also rotate adaptively at a certain angle. When the valve rod 6 rotates, the valve disc 7 fitted on the valve rod 6 rotates accordingly.
[0032] To increase the connection strength between the valve stem 6 and the partitioned air intake duct 5, a pipe clamp 10 is fitted onto the partitioned air intake duct 5. The valve stem 6 passes through the pipe clamp 10 and the partitioned air intake duct 5. A bushing 11 is provided between the valve stem 6, the pipe clamp 10, and the partitioned air intake duct 5. A retaining ring 12 is fitted onto the valve stem 6 outside the pipe clamp 10. A pair of bushings 11 and retaining rings 12 are provided. The bushing 11 forms a sealing structure between the valve stem 6, the pipe clamp 10, and the partitioned air intake duct 5, and also supports the rotation of the valve stem 6. The retaining ring 12 forms an axial limiting structure for the valve stem 6.
[0033] Comparison Appendix Figure 2 This embodiment adopts a modular design, with attached... Figure 2 The image shows one of the modules: the main suction duct 2 is composed of multiple pipe sections, with a T-joint 13 between each pipe section. The pump assembly 4 and the zoned suction control assembly 1 are both connected to the main suction duct 2 through the T-joint 13.
[0034] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
