Description

Technical Field

[0001] This utility model relates to the field of cutting bed equipment technology, and in particular to an auxiliary device for a cutting bed. Background Technology

[0002] As the core equipment in textile cutting, the cutting table's operational stability and processing precision directly affect production efficiency and finished product quality. Currently, to ensure that fabric remains flat and tightly adhered to the worktable during the cutting process, negative pressure adsorption technology is commonly used. This involves creating a negative pressure environment inside the cutting table using a fan, causing the fabric to be firmly adsorbed. However, in practical applications, during continuous operation, the fan is easily affected by factors such as mechanical vibration, airflow pulsation, and motor performance fluctuations, which can easily generate unstable airflow. This not only leads to uneven fabric adsorption and cutting deviations but may also cause fabric edges to curl or shift due to turbulent airflow, severely affecting cutting accuracy. Simultaneously, the combined effect of multiple noise sources during fan operation—mechanical friction, aerodynamic noise, and motor electromagnetic noise—significantly increases the noise level of the working environment. Long-term exposure to high noise levels not only damages the hearing health of operators but also reduces work efficiency.

[0003] While existing technologies offer solutions for airflow stabilization and noise reduction, these devices are often complex in structure and bulky, requiring valuable installation space on the cutting table and limiting the compact design and functional integration of the cutting table. Utility Model Content

[0009] Preferably, the pressure stabilizing box has an air guide hole for connecting to the cutting bed. The air guide hole is located on the side wall of the pressure stabilizing box away from the fan. The first air inlet pipe and the second air inlet pipe are respectively connected from the side walls on opposite sides of the pressure stabilizing box to the pressure stabilizing chamber.

[0010] Preferably, the air vent is located at the center of the side wall of the voltage regulator box.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. 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.

[0017] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figures 1 to 2 As shown, an auxiliary device for a cutting table, used to generate stable negative pressure adsorption of fabric on the cutting table, includes a fan 1, a pressure stabilizing box 2, and a silencer box 3. The pressure stabilizing box 2 has a pressure stabilizing chamber 21, and the silencer box 3 has a silencer chamber 31. The fan 1 is connected to a first air inlet pipe 41 and a first air outlet pipe 42. The first air inlet pipe 41 is connected to the pressure stabilizing chamber 21 of the pressure stabilizing box 2, which is used to generate negative pressure in communication with the cutting table. The first air outlet pipe 42 is connected to the silencer chamber 31 of the silencer box 3 to reduce the noise of the airflow output by the fan 1. The fan 1 provides strong adsorption force to adsorb the fabric, the pressure stabilizing box 2 effectively balances the negative pressure fluctuations, ensuring that the fabric is adsorbed flat and stable, preventing cutting displacement; the silencer box 3 significantly reduces the noise pollution of the fan 1 during operation, thus creating an efficient, stable, and quiet working state.

[0020] In this embodiment, the voltage stabilizing box 2 and the silencer box 3 are stacked vertically, with the voltage stabilizing box 2 located at the bottom of the silencer box 3, to reduce the area occupied by both. The fan 1 is disposed on the common side of the voltage stabilizing box 2 and the silencer box 3.

[0021] like Figure 3 As shown, the top of the voltage stabilizer box 2 is provided with a first clearance slope 22, and the bottom of the silencer box 3 is provided with a second clearance slope 32. The first clearance slope 22 and the second clearance slope 32 are arranged parallel to the first clearance slope 22. The stacked layout of the voltage stabilizer box 2 and the silencer box 3 lowers the overall center of gravity of the entire structure, making it more stable in operation and reducing the risk of shaking caused by the vibration of the fan 1.

[0022] In this embodiment, the silencer box 3 is fixed to the cutting bed by the bracket 6. A gap is formed between the first clearance slope 22 and the second clearance slope 32. The gap between the two slopes can serve as a buffer and heat dissipation space, preventing the two boxes from directly contacting each other due to vibration and generating additional noise, while also facilitating ventilation. In other embodiments, the silencer box 3 is fixedly connected to the voltage stabilizing box 2 by the first clearance slope 22 and the second clearance slope 32. The voltage stabilizing box 2 and the silencer box 3 are integrated into a single module. This integrated structure facilitates transportation, installation, and overall maintenance, and improves structural rigidity and stability.

[0023] Preferably, the pressure stabilizing box 2 and the silencer box 3 are coplanar in the vertical direction on the side away from the fan 1, eliminating the extra space waste caused by the unevenness of the box body.

[0024] In this embodiment, the fan 1 is a double-suction fan 1, that is, the fan 1 has two air inlets 11 and two air outlets 12. Inside the fan 1, a single rotating shaft drives two impellers to rotate, generating equal negative pressure at the two air inlets 11. The fan 1 is also connected to a second air inlet pipe 43 and a second air outlet pipe 44. The two air inlets 11 of the fan 1 are located at opposite ends of the fan 1, and the two air outlets 12 of the fan 1 are both located on the side of the fan 1 facing the silencer box 3. like Figure 2 and Figure 4 As shown, one end of the first air inlet pipe 41 is connected to one air inlet 11 of the ventilator 1, and the other end is connected to the pressure stabilizing chamber 21. One end of the second air inlet pipe 43 is connected to the other air inlet 11 of the ventilator 1, and the other end is connected to the pressure stabilizing chamber 21. The pressure stabilizing box 2 has an air guide hole 23 for connecting to the cutting bed, and the air guide hole 23 is located on the side wall of the pressure stabilizing box 2 away from the ventilator 1. Preferably, the air guide hole 23 is located at the center of the side wall. The first air inlet pipe 41 and the second air inlet pipe 43 are connected to the side walls on opposite sides of the pressure stabilizing box 2, that is, the first air inlet pipe 41 is located on both sides of the side wall where the air guide hole 23 is located.

[0025] When fan 1 is drawing in air, the rotation of the impeller generates periodic, minute pulsations. If there is only a single air intake pipe, these pulsations will be directly transmitted to the pressure stabilizing chamber 21 and the cutting bed working area, causing minute but potentially harmful fluctuations in the suction force. For high-precision cutting beds, these fluctuations may cause minute material displacements, affecting the cutting quality.

[0026] When the impeller of the dual-suction fan 1 rotates, at any given moment, one inlet 11 may be in a relatively strong suction state, while the other inlet 11 has a weaker suction. However, due to the symmetrical arrangement of the two inlet pipes, the airflow pulsations they generate are complementary in phase. When these two airflows converge in the pressure stabilizing chamber 21, their pulsations will interfere with, cancel each other out, and average out. When the instantaneous intake flow rate is slightly large, the pressure inside the chamber increases slightly, storing some gas; when the instantaneous flow rate is slightly small, the gas stored in the chamber is released to replenish it. This process effectively smooths the flow fluctuations from the fan 1, ensuring the airflow stability of the air guide 23.

[0027] The silencing chamber 3 is equipped with a partition 33, which divides the silencing cavity 31 into a first chamber 311 and a second chamber 312 that are interconnected. Both air outlets 12 of the fan 1 are connected to the first chamber 311. The silencing chamber 3 is also equipped with an exhaust port 34, which is connected to the second chamber 312. In this embodiment, the partition 33 has an L-shaped cross-section to increase the airflow path. Part of the sound wave propagates towards the exhaust port 34, while the other part is reflected back by the partition 33. The reflected sound wave interferes with and cancels out the incident sound wave, thereby attenuating the sound energy and achieving a silencing effect.

[0028] Preferably, the top of the fan 1 is provided with a protective cover 5, the fan 1 is built into the protective cover 5, and the protective cover 5 is fixed to the cutting bed.

[0029] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
