Description

Technical Field

[0001] This invention relates to the technical field of control cabinets, and in particular to a modular universal control cabinet for woodworking equipment and a method for adapting to multiple models. Background Technology

[0002] Control cabinets are typically dedicated to a single purpose, one machine for one use. In practice, control cabinets for the same equipment are generally similar in appearance, internal control system components, and wiring methods. Therefore, universal control cabinets have emerged. Universal control cabinets can adapt to multiple types of equipment. They typically have component chambers for modular installation of control components and also include cabinet doors for operating modules. For example, Chinese invention patent CN201910269505.0 discloses a universal mine explosion-proof PLC control cabinet and its application for tunnel boring machines. This universal control cabinet includes a wiring chamber and a component chamber, with a base at the bottom of the component chamber. The wiring chamber has terminals, including intrinsically safe through-wall terminals, high-voltage terminals, network cable through-wall terminals, fiber optic through-wall terminals, explosion-proof through-wall terminals, low-voltage flared terminals, high-voltage flared terminals, and 24V power supply terminal blocks. This invention is highly versatile, greatly shortening the safety certification time and production cycle of explosion-proof tunnel boring machines. Mass production of the same type of explosion-proof cabinets will also greatly save on the processing and manufacturing costs of explosion-proof cabinets. A single PLC control cabinet can adapt to the control needs of tunnel boring machines of various diameters (the number of control cabinets can be increased or decreased depending on the equipment), thus achieving the goal of greatly saving manufacturing costs and shortening the production cycle.

[0003] However, when configuring a general-purpose control cabinet with woodworking equipment, both electrical and mechanical connections are required. Electrical connections involve connecting the control components within the control cabinet to the motion and monitoring units of the woodworking equipment. Mechanical connections involve connecting the control cabinet to the frame of the woodworking equipment. This requires extensive wiring work near the woodworking equipment, involving passing cables through multiple layers of the control cabinet's wiring compartment. Furthermore, the wiring work takes place within the limited space of the wiring compartment, making the process laborious and cumbersome. Similarly, the mechanical connections between the general-purpose control cabinet and the woodworking equipment often use bolts. While these connections are secure, the weight of the cabinet and the limited space between the cabinet and the frame further complicate the process. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides a modular woodworking equipment universal control cabinet and a multi-model adaptation method that adopts a modular design, with each module assembled independently and centrally, reducing assembly difficulty, enabling rapid adaptation to various types of woodworking equipment, and achieving high working efficiency.

[0005] This invention discloses a modular universal control cabinet for woodworking equipment, comprising a cabinet body, an internal component chamber, a mounting frame for installing electrical components within the component chamber, and a cabinet door mounted on the front operating port of the component chamber; it also includes a sub-frame connected to the frame or foundation of the woodworking equipment, a lower end of a plug plate connected to the sub-frame, and an upper end of the plug plate inserted into a slot mounted on the back or bottom of the mounting frame; multiple end posts mounted on the top of the cabinet body, with the lower ends of the end posts extending into the component chamber and the upper ends extending above the cabinet body; a housing sealed on the top of the cabinet body, a wiring chamber located on the lower end face of the housing, and multiple wiring sleeves mounted on the top of the housing. The conduits are aligned vertically with multiple end posts. The lower ends of multiple wiring sleeves extend into the wiring chamber of the housing, and the lower ends of the multiple wiring sleeves are matched with multiple end posts. The upper ends of the multiple wiring sleeves extend above the housing.

During operation, in the control cabinet workshop, the corresponding control buttons and displays are installed on the cabinet door, and the corresponding electrical components are installed on the mounting bracket. The wiring ports of the electrical components are connected to the lower ends of the corresponding multiple end posts through cables.

During the installation of the housing, it is gradually moved closer to the cabinet, thereby gradually inserting the multiple wiring sleeves and end posts into place. A sealing component is installed between the housing and the cabinet. Existing technologies will not be elaborated here. The sealing components maintain a seal between the housing and the cabinet, reducing the entry of sawdust, powder, and other impurities into the wiring chamber, which could cause problems such as leakage and corrosion. This allows for rapid electrical connection between the electrical components in the cabinet and the electrical components of the woodworking equipment. Compared to existing technologies, the control cabinet body, wiring section, and mechanical connection section are treated as independent modules, which are assembled independently in different work areas. This provides a larger operating space, more comprehensive supporting facilities, and eliminates the need for wiring operations.

Detailed Implementation

[0018] To facilitate understanding of the present invention, a more complete description will be given below with reference to the accompanying drawings. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

[0019] A method for adapting a modular woodworking equipment universal control cabinet to multiple models, including: S1. In the control cabinet assembly workshop, install electrical control components onto the mounting frame 2, assemble multiple end posts 7 onto the cabinet 1, and assemble multiple wiring sleeves 9 onto the housing 8. S2. Electrically connect the electrical control components to the lower ends of the corresponding multiple end posts 7, and close the cabinet door 3; S3. In the woodworking equipment assembly workshop, install the sub-frame 4 onto the woodworking equipment or foundation, connect the electrical components that drive the equipment to the upper end of the corresponding wiring sleeve 9 via cables, and place multiple cable clips into the multiple wire holes 22 of the bracket 21. S4. Transport cabinet 1 to the woodworking equipment assembly workshop, adjust the position of cabinet 1 so that the upper end of the insert plate 5 is inserted into the slot 6, and complete the quick installation of cabinet 1. S5. Lower the housing 8 and install it onto the cabinet 1. During the installation of the housing 8, drive multiple wiring sleeves 9 to be fitted onto the upper ends of multiple end posts 7 to complete the electrical connection of multiple cables. S6. The wiring chamber inside the housing 8 is evacuated or inflated through the air nozzle 10. The pressure change in the wiring chamber is monitored by the pressure sensor 11. Based on the pressure change, the sealing status is alarmed by the corresponding electrical components in the cabinet 1.

[0020] Based on the above adaptation method, the following embodiments are proposed: Example 1, as Figures 1 to 5 As shown, a modular woodworking equipment universal control cabinet adopts a modular design, consisting of three independent modules: a main cabinet module, a wiring module, and a mechanical connection module. The main cabinet module includes a cabinet body 1, a mounting bracket 2, and a cabinet door 3. The wiring module includes a housing 8, multiple wiring sleeves 9, a sealing kit 12, an air nozzle 10, and a pressure sensor 11. The mechanical connection module includes a sub-frame 4, a plug plate 5, and a slot 6. Specifically, the cabinet body 1 has a component chamber inside, and the component chamber is equipped with a mounting bracket 2 for installing electrical components. The front operating port of the component chamber is equipped with... Cabinet door 3 and sub-frame 4 are connected to the frame or foundation of the woodworking equipment. The lower end of insert plate 5 is connected to sub-frame 4, and the upper end of insert plate 5 is inserted into slot 6. Slot 6 is installed on the back or bottom of mounting bracket 2. Multiple end posts 7 are installed on the top of cabinet 1. The lower ends of multiple end posts 7 extend into the component chamber of cabinet 1, and the upper ends of multiple end posts 7 extend above cabinet 1. Housing 8 is sealed and installed on the top of cabinet 1. A wiring chamber is set on the lower end face of housing 8. Multiple wiring sleeves 9 are installed on the top of housing 8. Multiple wiring sleeves 9 are aligned vertically with multiple end posts 7. Multiple wiring sleeves 9 are installed vertically with multiple end posts 7. The lower end of the sleeve 9 extends into the wiring chamber of the housing 8. The lower ends of multiple wiring sleeves 9 are respectively matched with multiple end posts 7. The upper ends of multiple wiring sleeves 9 extend above the housing 8. A sealing kit 12 is provided between multiple wiring sleeves 9 and the housing 8. A vent hole 14 is provided on the lower side wall of multiple wiring sleeves 9. A sealing kit 2 13 is provided between multiple end posts 7 and the cabinet 1. An air nozzle 10 is installed on the housing 8. The inner end of the air nozzle 10 extends into the wiring chamber of the housing 8. A pressure sensor 11 is installed at the lower end of the air nozzle 10. The pressure sensor 11 is located at the junction of the housing 8. In the cable cavity; it should be understood that multiple sealing kits 12 and multiple sealing kits 13 can be sealed by methods such as potting, spiral fastening or epoxy resin casting. Multiple sealing kits 12 improve the sealing performance between multiple wiring sleeves 9 and housing 8, and multiple sealing kits 13 improve the sealing performance between multiple end posts 7 and cabinet 1. The air nozzle 10 is preferably a universal air nozzle for automobile tires, but it can also be replaced by a quick connector with a one-way valve. The cabinet door 3 is connected to the cabinet 1 by a hinge, and a sealing ring is provided between the cabinet door 3 and the cabinet 1 to prevent sawdust and other powders from entering the interior of the cabinet 1.

[0021] In an embodiment of the present invention, the working process of the above-mentioned modular woodworking equipment universal control cabinet is as follows: In the control cabinet workshop, the corresponding control buttons and displays are installed on the cabinet door 3, the corresponding electrical components are installed on the mounting frame 2, and the wiring ports of the electrical components are connected to the lower ends of the corresponding multiple end posts 7 through cables. The wiring and wiring methods, the selection of electrical components, etc. are all existing technologies and will not be described in detail here. In the woodworking equipment workshop, the wiring ports of each electrical component on the woodworking equipment are connected to the upper ends of the corresponding multiple wiring sleeves 9 through cables. The sub-frame 4 is installed with the frame or foundation of the woodworking equipment through bolt pairs. The cabinet 1 is transported to the woodworking equipment workshop, and the position of the cabinet 1 is adjusted so that the upper end of the insert plate 5 is inserted into the slot 6, completing the quick mechanical connection between the cabinet 1 and the woodworking equipment. The position of the housing 8 is adjusted so that the multiple wiring sleeves 9 are aligned vertically with the multiple end posts 7. The housing 8 is fastened to the top of the cabinet 1 using multiple bolts. During the process, it gradually approaches the cabinet 1, thereby driving multiple wiring sleeves 9 and multiple end posts 7 to be gradually inserted into place. When the end post 7 is inserted and connected to the wiring sleeve 9, the air in the wiring sleeve 9 is discharged through the exhaust hole 14, which improves the smoothness of the wiring connection between the wiring sleeve 9 and the end post 7. A sealing component is set between the housing 8 and the cabinet 1. The sealing component is existing technology and will not be described in detail here. The sealing component keeps the housing 8 and the cabinet 1 sealed. After the housing 8 is sealed and installed on the cabinet 1, the air pipe of the vacuum pump or air pump is connected to the outer end of the air nozzle 10. When the vacuum pump is running, it evacuates the wiring chamber of the housing 8. The vacuum state is beneficial to improving the insulation performance between the multiple end posts 7 and the multiple wiring sleeves 9 and reducing the corrosion of moisture and impurities in the air. When the air pump is running, it fills the wiring chamber with inert gas (such as nitrogen or argon). The inert atmosphere is beneficial to improving the insulation performance between the multiple end posts 7 and the multiple wiring sleeves 9 and reducing the corrosion of moisture and impurities in the air, thus improving the reliability of the wiring.The pressure sensor 11 is wirelessly connected to the corresponding monitor installed on the mounting bracket 2. As an intelligent control scheme, the pressure sensor 11 can be a diffused silicon pressure transmitter, which outputs a 4-20mA analog signal or an RS485 digital signal (Modbus RTU protocol) to the programmable logic controller (PLC) inside the cabinet 1. The PLC has preset upper and lower pressure thresholds. When the monitored pressure value exceeds the threshold range or the pressure drop rate exceeds the set value, the PLC determines that the seal has failed and drives the alarm indicator and buzzer to sound an alarm. At the same time, the fault information can be uploaded to the factory's host computer system. The above control scheme is all existing technology, and those skilled in the art can implement it based on the description in this specification and the accompanying drawings. The pressure sensor 11 detects the air pressure in the wiring chamber of the housing 8. When the air pressure is excessively depressurized, it determines that the seal between the housing 8 and the cabinet 1 has failed, and the monitor sounds an alarm to remind the staff to carry out maintenance, thereby reducing the problem of leakage and corrosion caused by sawdust and other impurities entering the wiring chamber, thus completing the rapid electrical connection between the electrical components in the cabinet 1 and the electrical components of the woodworking equipment.

[0022] The technical advantages of this embodiment are as follows: Compared with the prior art, the control cabinet body, wiring section, and mechanical connection section are treated as independent modules, and are assembled independently in different working areas. This provides a larger operating space, more comprehensive supporting facilities, and eliminates the need for wiring operations. Furthermore, the independent modules can be quickly connected and adapted to adapt to various types of woodworking equipment without modifying the wiring inside the cabinet, simplifying on-site adaptation and installation operations, reducing wiring errors, and improving work efficiency. At the same time, by setting up the vent 14, sealing kit one 12, and sealing kit two 13, the smoothness of the insertion and the overall sealing performance are improved. By setting up the air nozzle 10 and the pressure sensor 11, active control and real-time monitoring of the internal environment of the wiring chamber are realized, and automatic alarm of the sealing status is realized through PLC, further improving the reliability and intelligence level of the electrical connection. As an alternative, the air nozzle 10 can also be integrally formed with the housing 8 as an interface with internal threads, directly connecting to a standard air pipe quick connector. The air extraction or inflation operation can be completed by a handheld air pump, or it can be integrated into the control cabinet and automatically executed by a miniature air pump.

[0023] Example 2, as Figure 6 and Figure 7As shown, based on Embodiment 1, the modular woodworking equipment universal control cabinet provided in this embodiment further includes a guide shell 15, a guide shell 27, a handle 16, a handle 28, a hinge component 19, a secondary upright plate 20, a bracket 21, a wire hole 22, a protrusion 1 23, and a protrusion 24. The guide shell 15 and the guide shell 27 are semi-funnel-shaped, and are arranged opposite to each other to form a funnel. The small end of the funnel matches the wiring sleeve 9. One edge of the guide shell 15 and the guide shell 27 is connected by the hinge component 19. The handle 16 is installed on the other side of the guide shell 15, and the handle 28 is installed on the other side of the guide shell 27. 18 is arranged opposite to handle 16. The lower end of the sub-upper plate 20 is connected to the insert plate 5. The upper end of the sub-upper plate 20 is equipped with bracket 21. Multiple wire holes 22 are provided on the bracket 21. Multiple slots are provided on both the upper and lower end surfaces of the bracket 21. The multiple slots are connected to the multiple wire holes 22 respectively. A protrusion 23 is provided on the left side of one end of the multiple slots. A protrusion 24 is provided on the right side of the other end of the multiple slots. The gap between protrusion 23 and the slot and the gap between protrusion 24 and the slot are slightly larger than the cable diameter. The guide shell 15 and the guide shell 27 are both made of high temperature resistant materials, such as ceramic materials or polyether ether ketone (PEEK) composite materials, to withstand the high temperature when the solder melts.

[0024] Furthermore, the working process of this embodiment is as follows: When connecting the cables of the electrical components of the woodworking equipment to the wiring sleeve 9, the end of the cable is inserted into the upper end of the corresponding wiring sleeve 9. The guide shell 15 and guide shell 2 17 are opened around the hinge component 19 and fitted onto the outside of the cable using handle 16 and handle 2 18, with the small end of the funnel aligned with the upper end of the wiring sleeve 9. Solder is then filled into the funnel formed by guide shell 15 and guide shell 2 17. A handheld... A hot air gun or high-frequency induction heater is used to heat and melt the solder. The molten solder is poured into the gap between the connector sleeve 9 and the cable end under the gravity of the funnel. After the solder cools and solidifies, the guide shell 15 and guide shell 27 are opened and removed around the hinge component 19 by using handle 16 and handle 2 18. The heat shrink tubing is then fitted onto the sealing kit 12, the connector sleeve 9, and the cable end. The residual heat of the solder causes the heat shrink tubing to shrink, completing the connection of one cable. The above operation is repeated to complete all connections. The cable connection is secure and reliable, significantly reducing the gap between the wiring sleeve 9 and the cable end, resulting in excellent connection performance. Simultaneously, the gaps between protrusion 1 23 and the slot, protrusion 2 24 and the slot, and the slot itself form a winding cable routing groove. Multiple cables of the woodworking equipment's electrical components are inserted into multiple wire holes 22 through this groove, allowing each cable to pass through one of the holes. Protrusions 1 23 and 2 24 prevent the cables from slipping out of the holes 22, allowing the support structure formed by the sub-plate 20 and bracket 21 to further support the cables. The multiple wire holes 22 guide the cables, making it easier to adjust the curvature of the cables between the bracket 21 and the housing 8. This reduces stress on the cables after the housing 8 is installed on the cabinet 1. As an alternative, soldering can be replaced with conductive silver adhesive bonding or cold-pressed terminals pressed into the pre-installed metal springs in the wiring sleeve 9 to accommodate lead-free processes or improve production efficiency.

[0025] The technical advantages of this embodiment are as follows: the funnel structure formed by the first guide shell 15 and the second guide shell 17 enables rapid and high-quality welding at the connection between the cable and the connector sleeve 9, improving the conductivity and mechanical strength of the connection. Furthermore, the funnel structure is reusable, reducing costs. By setting the secondary upright plate 20, the bracket 21, and the wire hole 22 with protrusions, effective support, guidance, and fixation of the cable are achieved, reducing cable stress and improving the long-term reliability of the connection. It should be noted that a smooth nylon bushing can be provided on the inner wall of the wire hole 22 on the bracket 21 to reduce wear during cable insertion, which is particularly important in high-frequency vibration environments.

[0026] Example 3, as Figures 8 to 10As shown, based on Embodiment 1, the modular woodworking equipment universal control cabinet provided in this embodiment further includes a limiting protrusion 25, a top rod 26, a limiting pressure block 27, a spring 28, a shock-absorbing pad 29, a connecting frame 30, a horizontal shaft 31, a rubber sleeve 1 32, a spring shock absorber 33, a rubber sleeve 2 34, and a rubber sleeve 35. The upper end of the insert plate 5 has protruding limiting protrusions 25 on both sides. Two top rods 26 are slidably inserted into both sides of the slot 6. Limiting pressure blocks 27 are installed on the inner ends of both top rods 26. The inner ends of two springs 28 are connected to both sides of the slot 6, and the outer ends of two springs 28 are connected to the two top rods 26. The shock-absorbing pad 29 is installed inside the slot 6. The top rods 26 are placed between the insert plate 5 and the slot 6. The sub-frame 4 includes a connecting frame 30. One end of the connecting frame 30 facing the insert plate 5 has a connecting hole, and the other end of the connecting frame 30 has a connecting hole. Multiple mounting holes are provided. A horizontal shaft 31 is installed at the lower end of the insert plate 5. The horizontal shaft 31 passes through the connecting hole of the connecting frame 30. A rubber sleeve 32 is provided between the horizontal shaft 31 and the connecting hole of the connecting frame 30. One end of the spring damper 33 is rotatably connected to the insert plate 5 through a shaft 1. A rubber sleeve 34 is provided between the shaft 1 and the spring damper 33. The other end of the spring damper 33 is rotatably connected to the connecting frame 30 through the shaft 2. A rubber sleeve 35 is provided between the shaft 2 and the spring damper 33. It should be noted that the insert plate 5, the horizontal shaft 31, the shaft 1 and the shaft 2 are all metal parts, and the surface can be galvanized or Dacromet treated to prevent rust. The rubber sleeves 32, 34 and 35 are preferably natural rubber or polyurethane elastomers, which have good wear resistance and damping characteristics. The spring damper 33 can be a commercially available cylindrical helical spring damper or a rubber-metal composite damper.

[0027] In an embodiment of the present invention, the working process is as follows: multiple bolts are used to pass through multiple mounting holes of the connecting frame 30 and securely connect it to the frame or foundation of the woodworking equipment, thereby realizing the installation of the connecting frame 30 and the insert plate 5. The spring shock absorber 33 assists in supporting the insert plate 5, so that the connecting frame 30, the insert plate 5 and the spring shock absorber 33 form a triangular support structure, improving the support stability of the cabinet 1. When the upper end of the insert plate 5 is inserted into the slot 6, the two limiting protrusions 25 push the two limiting pressure blocks 27 outward. When the upper end of the insert plate 5 is inserted into the slot, the two limiting protrusions 25 pass over the two limiting pressure blocks 27 respectively, and the elastic force of the two springs 28 pushes the two top rods 26 inward, so that the two The top rod 26 presses the two limiting blocks 27 tightly against the outer walls of the two insert plates 5 on both sides. At the same time, the upper ends of the two limiting blocks 27 are engaged with the lower edges of the two limiting protrusions 25, producing a "click" sound to remind the operator of the insertion status and improve the insertion reliability of the insert plates 5 and slots 6. At this time, the shock-absorbing pad 29 is placed between the insert plates 5, slots 6 and cabinet 1 to achieve a certain shock absorption effect. By setting rubber sleeve 1 32, rubber sleeve 2 34 and rubber sleeve 3 35, the vibration of the woodworking equipment is consumed. By setting spring shock absorber 33, the vibration is further consumed, so that the vibration generated by the woodworking equipment during operation is transmitted to the insert plates 5 and cabinet 1 as little as possible, thereby reducing the vibration of electrical components and wiring inside cabinet 1.

[0028] The technical advantages of this embodiment are as follows: Through the cooperation of the limiting protrusion 25, the limiting pressure block 27, and the spring 28, automatic limiting and positioning prompts (click sound) are achieved when the insert plate 5 and slot 6 are inserted into place, improving the convenience and reliability of installation; by setting a multi-stage damping structure (dampening pad 29, rubber sleeve 1 32, rubber sleeve 2 34, rubber sleeve 35, spring damper 33), an effective damping path is formed, significantly reducing the impact of woodworking equipment vibration on the precision electrical components inside the control cabinet, and improving the long-term stability and service life of the equipment; as an alternative, if the vibration amplitude on site is small, the spring damper 33 can be omitted, and only rubber sleeve 1 32, rubber sleeve 2 34, and rubber sleeve 35 can be retained as damping elements to reduce costs and simplify the structure.

[0029] The overall work process, such as Figures 1 to 10As shown, this invention discloses a modular universal control cabinet for woodworking equipment. During operation, firstly, in the control cabinet assembly workshop, electrical control components are installed onto the mounting frame 2, multiple end posts 7 are assembled onto the cabinet body 1, and a second sealing kit 13 is installed between the multiple end posts 7 and the cabinet body 1. Multiple wiring sleeves 9 are assembled onto the housing 8, and a first sealing kit 12 is installed between the multiple wiring sleeves 9 and the housing 8. The electrical control components are electrically connected to the lower ends of the corresponding multiple end posts 7, and the cabinet door 3 is closed. In the woodworking equipment assembly workshop, the sub-frame 4 (including the connecting frame 30) is bolted onto the woodworking equipment or foundation. The cables of the electrical components driving the equipment are guided through the wire holes 22 on the bracket 21, and then, using a funnel formed by the first guide shell 15 and the second guide shell 17, along with solder, the cable ends are securely connected to the upper ends of the corresponding wiring sleeves 9. Finally, the cabinet body 1 is transported to the woodworking equipment assembly workshop. In the equipment assembly workshop, the position of cabinet 1 is adjusted so that the upper end of the insert plate 5 is inserted into the slot 6. When a "click" sound is heard, the fitting is in place. During this insertion process, components such as spring shock absorbers 33 and rubber sleeves provide shock absorption. The position of housing 8 is adjusted so that multiple wiring sleeves 9 are aligned vertically with multiple end posts 7. Multiple bolts are used to fasten housing 8 to the top of cabinet 1. During the installation of housing 8, it is gradually moved closer to cabinet 1, thereby driving multiple wiring sleeves 9 and multiple end posts 7 to be gradually inserted into place. Air is pumped or inflated into the wiring chamber inside housing 8 through air nozzle 10. Pressure sensor 11 monitors the pressure change in the wiring chamber and transmits the signal to PLC inside cabinet 1. PLC judges the sealing status according to the preset threshold. When the pressure is abnormal, an alarm is issued through the indicator light or buzzer on cabinet door 3, thereby realizing automatic early warning of sealing failure.

[0030] What needs to be understood is: (1) Exposed moving parts: The sliding fit between the push rod 26 and the slot 6 is in long-term contact with wood dust, which may cause jamming. As a preferred solution, a dustproof sealing ring (such as an O-ring made of nitrile rubber or a dustproof felt ring) is set at the fit gap between the push rod 26 and the slot 6, and high-temperature resistant grease is applied during assembly. (2) Wear of relatively moving parts: The limiting protrusion 25 and the limiting pressure block 27 may wear during repeated insertion and removal. Surface hardening or wear-resistant alloy plates can be embedded in the contact surface of the limiting pressure block 27 to improve service life. (3) Ease of replacement of shock-absorbing components: Rubber sleeve 1 32, rubber sleeve 2 34, rubber sleeve 3 35 and spring shock absorber 33 are all consumables and may age and fail after long-term operation. The end of the horizontal shaft 31 can be fixed with a cotter pin or snap ring to facilitate the replacement of the rubber sleeve after disassembly. The two ends of the spring shock absorber 33 can be connected to shaft 1 and shaft 2 by threaded connection with locking nuts to facilitate replacement. (4) Heat dissipation and protection of electrical components: The electrical components (such as frequency converters, PLCs, etc.) installed inside the cabinet 1 will generate heat when working. Ventilation louvers can be installed on the side wall or cabinet door 3 of the cabinet 1 and dust filters can be installed. At the same time, an axial flow fan can be installed inside the cabinet 1 for forced convection heat dissipation. These are all conventional designs in this field and will not be elaborated here. For equipment that operates in a high dust environment for a long time, a positive pressure dust prevention system can also be installed inside the cabinet 1. That is, clean compressed air is introduced through the air nozzle to make the pressure inside the cabinet slightly higher than that outside, effectively preventing sawdust dust from entering. (5) Existing technology description of the control scheme: The signal processing of pressure sensor 11, the communication protocol with PLC (such as 4-20mA two-wire system or RS485 Modbus), the pressure threshold comparison and alarm output program inside PLC are all existing mature technologies. Those skilled in the art can implement them based on conventional electrical control principles without any creative effort.

[0031] The main functions achieved by this invention are: - Adopting a modular design, the control cabinet body, wiring section, and mechanical connection section are treated as independent modules, which are assembled independently in different work areas. This simplifies on-site adaptation and installation operations, reduces wiring and threading errors, improves work efficiency, and truly achieves "plug and play" equipment adaptation. - By setting up a funnel structure consisting of a first guide shell and a second guide shell, a fast and high-quality welding connection between the cable and the connecting sleeve is achieved, replacing the traditional method of screwing or crimping in a confined space. The connection is firm and has good sealing performance. Furthermore, the funnel assembly can be reused, reducing the manufacturing cost of auxiliary tools. - By setting up a secondary support plate and a bracket with guide holes and anti-detachment protrusions, effective support and stress relief of the cable are achieved, avoiding loosening of the connection point due to the cable's own weight or vibration. At the same time, the slot structure on the bracket allows the cable to be inserted without disassembling the terminal, which is convenient for later maintenance. - By setting limit protrusions, spring-loaded limit pressure blocks, and positioning prompts, the mechanical connection can be quickly positioned and reliably locked, reducing installation difficulty and avoiding poor contact or mechanical loosening caused by improper insertion. - By setting up multi-level damping elements (damping pads, multiple rubber sleeves, spring dampers), an effective vibration isolation path is formed, protecting the precision electrical components inside the cabinet. It is especially suitable for high-frequency vibration environments generated by woodworking equipment (such as planers, milling machines, and sanders). - By installing air nozzles and pressure sensors on the sealed wiring chamber and integrating them into the PLC control system, active intervention in the wiring environment (vacuum or inert gas protection) and real-time monitoring and automatic alarm of the sealing status are realized, which significantly improves the corrosion resistance and insulation performance of electrical connections and extends the service life of the equipment in harsh woodworking dust environments. - The multi-model adaptation method of the present invention decomposes the assembly work into different workshops and different time periods, which reduces the skill requirements of on-site technicians, shortens the equipment delivery cycle, and has strong industrial practical value.
