[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0025] Example 1: This utility model embodiment discloses a soundproof box for a dispensing machine, according to the attached... Figure 1-3 As shown, it includes a soundproof box frame 1, an automatic lifting door 2, and an intelligent linkage control system 3;

[0026] The soundproof enclosure frame 1 is constructed from welded square tubing to form a hexahedral structure. Sound-absorbing strips are installed at each connection point to effectively reduce sound leakage at the enclosure joints. The inner lining is a micro-perforated aluminum plate 121; the small pores on its surface absorb sound energy, reducing noise reflection. The porous sound-absorbing cotton 122, fixedly connected to the micro-perforated aluminum plate 121, further enhances the sound absorption effect. The porous structure causes sound waves to repeatedly reflect and rub within the pores, converting sound energy into heat energy. A damping adhesive layer 123 is attached to the porous sound-absorbing cotton 122, increasing the structure's damping characteristics, suppressing enclosure vibration, and thus reducing noise transmission caused by vibration.

[0027] The automatic lifting door 2 is slidably connected to the soundproof box frame 1. The soundproof box frame 1 is provided with a drive mechanism 23 for controlling the automatic lifting door 2 to lift. The automatic lifting door 2 is provided with an observation window 22. The observation window 22 includes an outer tempered glass 221 on the outside, an inner tempered glass 223 on the inside, and a soundproof membrane 222 between the outer tempered glass 221 and the inner tempered glass 223.

[0028] The design of the outer tempered glass 221, the middle soundproof membrane 222 and the inner tempered glass 223 ensures that the observation window 22 is clear while also providing sound insulation to reduce equipment noise.

[0029] The automatic lifting door 2 is slidably connected to the soundproof box frame 1 and its lifting and lowering are controlled by the drive mechanism 23. The drive mechanism 23 adopts a linear guide rail + cylinder method. The linear guide rail ensures that the lifting door lifts and lowers smoothly and accurately, while the cylinder provides power and has a fast response speed, enabling the lifting and lowering action to be completed in a short time. A magnetic sealing strip 21 is installed on the door, which is composed of an aluminum silicate fiber layer and has good flexibility and magnetism. When the automatic lifting door 2 is closed, the magnetic sealing strip 21 is tightly attached to the soundproof box frame 1. Utilizing magnetic adsorption and the sealing performance of aluminum silicate fiber, noise is effectively prevented from leaking from the gap between the door and the frame.

[0030] In the initial state of the equipment, the automatic lifting door 2 is in the open position. When the work is ready to begin, pressing the start button 33 activates the intelligent linkage control system 3, which controls the drive mechanism 23 to lower the automatic lifting door 2. After the work is completed, a work completion signal is received, and the automatic lifting door 2 rises to facilitate the removal of the workpiece.

[0031] The intelligent linkage control system 3 is installed on the soundproof box frame 1 and is used to control the operation of the automatic lifting door 2.

[0032] The intelligent linkage control system 3 includes:

[0033] Infrared light curtain 31 is mounted on the soundproof box frame 1 and is used to set the light curtain detection area;

[0034] An emergency stop button 32 is located on the front of the soundproof box frame 1. The emergency stop button 32 is used to control the automatic lifting door 2.

[0035] The start button 33 is located on the front of the soundproof box frame 1. The start button 33 is used to control the start of the equipment.

[0036] Infrared light curtain 31 is configured with a detection area. When an object or person enters the detection area, infrared light curtain 31 will emit a signal, interlocking with automatic lifting door 2 to prevent automatic lifting door 2 from closing in the presence of obstacles, ensuring operational safety. Emergency stop button 32 is located on the front of the soundproof box frame 1. In case of emergency, the operator can quickly press emergency stop button 32 to stop the automatic lifting door 2, ensuring the safety of equipment and personnel.

[0037] The start button 33 is used to control the start of the equipment. When pressed, it triggers the start of the entire operation process.

[0038] The intelligent linkage control system 3 also includes an equipment linkage interface 34 mounted on the soundproof box frame 1. The equipment linkage interface 34 establishes a bidirectional communication connection with the dispensing machine 4. The equipment linkage interface 34 supports PLC / IO signal interface, enabling bidirectional communication with the dispensing machine 4 and achieving automated control. For example, when the automatic lifting door 2 descends to its designated position, it sends a start signal to the dispensing machine 4 via the equipment linkage interface 34 and simultaneously receives a completion signal from the dispensing machine 4, controlling the lifting door to rise.

[0039] The soundproof enclosure frame 1 is a hexahedral structure formed by welding square tubes, with sound-absorbing strips installed at each connection point. The frame 1 is lined with a micro-perforated aluminum plate 121, and porous sound-absorbing cotton 122 is fixedly connected to the micro-perforated aluminum plate 121. A damping adhesive layer 123 is fixedly connected to the porous sound-absorbing cotton 122. A magnetic sealing strip 21 is fixedly connected to the automatic lifting door 2.

[0040] The multi-layer sound insulation structure design, including a square tube welded hexahedron, sound-absorbing strips, micro-perforated aluminum plate 121, porous sound-absorbing cotton 122, and damping adhesive layer 123, can effectively attenuate noise, achieving a noise reduction of ≥25dB(A), providing a relatively quiet working environment for staff.

[0041] The infrared light curtain 31 has a response time of ≤10ms and is interlocked with the door, improving operational safety. Emergency stop button 32 and start button 33 facilitate operator control of the equipment. The equipment linkage interface 34 supports PLC / IO signal interface, enabling intelligent linkage with dispensing machine 4, optimizing the work process and avoiding cycle time loss.

[0042] This invention effectively solves the noise problem generated during operation of traditional desktop dispensing machines 4 without modifying existing equipment, protecting the health of workers. Compared with replacing with silent equipment, the modification cost is only 18% to 22% of purchasing new silent equipment, significantly reducing enterprise costs. Furthermore, it has good compatibility, adapting to mainstream desktop dispensing machines 4 on the market, with an installation and adaptation time of ≤2 man-hours, reducing downtime for modification. At the same time, the operator's field of vision is preserved at least 70% of the original field of vision, ensuring that the sound insulation device does not severely affect the operator's vision and guaranteeing smooth operation.
