Description

TECHNICAL FIELD

[0001] The application relates to the technical field of cutting equipment, in particular to cutting equipment for electric sofa support production. BACKGROUND

[0002] The electric sofa support is a core component for ensuring the function and stability of the sofa, mainly including a support frame, a driving assembly, a connecting hinge and a C-shaped guide rail. Among them, the support frame bears the overall weight of the sofa and the user's pressure, and maintains the basic form of the sofa; the driving assembly provides power for the angle adjustment of the sofa, and is the key to realize the inclination of the backrest and the extension of the footrest; the connecting hinge is responsible for connecting the backrest, the footrest and the main frame, and ensures smooth rotation and stable connection of the active parts.

[0003] In the electric sofa support, the C-shaped guide rail is a common structural design, which plays an important role in the angle adjustment system and is mainly used to realize multi-angle adjustment and smooth movement of the backrest, footrest and other components, so that users can flexibly adjust to a comfortable state according to the use requirements, and avoid jamming or shaking during adjustment. The C-shaped guide rail is generally formed by a bending machine, and the bending process can accurately shape the C-shaped cross-section structure that meets the design requirements, ensuring the adaptability of the C-shaped guide rail and the structural strength thereof; however, due to the differences in the length requirements of the C-shaped guide rail for different specifications of electric sofas, a cutting machine is needed to cut and segment the C-shaped guide rail, so that the length of the C-shaped guide rail can accurately match the overall assembly size of the sofa support, ensuring the cooperation of the components and further improving the use stability and adjustment smoothness of the electric sofa.

[0004] The existing cutting equipment for electric sofa support production has significant process shortcomings when cutting the C-shaped guide rail. Since the side wall of the C-shaped guide rail lacks a special supporting structure during cutting, when the cutting blade contacts and cuts the C-shaped guide rail, the cutting force generated by the blade will directly extrude the side wall of the C-shaped guide rail. Without support and buffering, this extrusion is easy to cause bending deformation of the side wall of the C-shaped guide rail, which further affects the assembly precision of the C-shaped guide rail and other components of the sofa support, causing installation jamming or abnormal clearance, and also reducing the stability of the adjustment function of the C-shaped guide rail, ultimately resulting in poor overall cutting effect and difficulty in meeting the production quality requirements of the electric sofa support.

[0018] 2.

[0034] A driving motor 10 is fixedly installed at the outside of one side of the C-shaped mounting bracket 7 close to one of the driving rollers 8, and the output end of the driving motor 10 is coaxially fixed with one end of one of the driving rollers 8.

[0035] A plurality of friction blocks 11 are fixedly installed at equal intervals on the outside of the driving belt 9.

[0036] The telescopic regulation assembly comprises a liquid collecting cavity 12 and a first air cylinder 13, the liquid collecting cavity 12 is arranged in the middle of the inside of the positioning cross beam 6, the first air cylinder 13 is vertically fixedly installed on the outside of the bottom end of the cutting table 1 close to the liquid collecting cavity 12, the output end of the first air cylinder 13 penetrates through and is slidingly installed on one side of the inside of the liquid collecting cavity 12, the output end of the first air cylinder 13 is fixedly installed with a piston block 14 at the top end, and the piston block 14 is in sliding sealing connection with the inner wall of the liquid collecting cavity 12.

[0037] The limiting through hole 15 is horizontally arranged in the inside of the two side edges of the positioning cross beam 6, two piston rods 16 are symmetrically slidingly and sealingly installed in the inside of the limiting through hole 15, one end of each piston rod 16 is fixedly installed on the outside of one side of the C-shaped mounting bracket 7, the positioning cross beam 6 is provided with a liquid guide channel 17 at the position between the limiting through hole 15 and the liquid collecting cavity 12, one end of the liquid guide channel 17 is in conductive connection with the top end of the inside of the liquid collecting cavity 12, and the other end of the liquid guide channel 17 is in conductive connection with the middle of the inside of the limiting through hole 15.

[0038] In this embodiment, when the C-shaped guide rail is cut by using the cutting equipment for producing the electric sofa support, the working process thereof is gradually developed around the logic of “C-shaped guide rail conveying and positioning, support spacing regulation, accurate cutting and product conveying”, and each component cooperates to realize deformation prevention cutting, and the specific principle is as follows:

[0039] Firstly, after the equipment is started, the operator issues an operation instruction through the control panel 5, starts the driving motor 10, and drives one of the driving rollers 8 coaxially fixed to the output end of the driving motor 10 to rotate, since the driving rollers 8 are all penetratingly and rotatably installed in the inside of the C-shaped mounting bracket 7 and the external transmission sleeve is provided with the driving belt 9, the rotation of the single driving roller 8 can drive the remaining driving rollers 8 to synchronously rotate through the driving belt 9, thereby forming continuous conveying power. At this time, the C-shaped guide rail to be cut is placed between the driving belts 9 of the two C-shaped mounting brackets 7, the friction blocks 11 fixedly arranged at equal intervals outside the driving belts 9 can increase the friction force with the surface of the C-shaped guide rail, so that slipping in the conveying process is avoided, and then the C-shaped guide rail is stably conveyed to the above of the cutting seam 2 in the middle of the cutting table 1, and the positioning cross beams 6 on both sides of the cutting seam 2 of the cutting table 1 can play a preliminary positioning role from both sides of the C-shaped guide rail, so as to ensure that the cutting position of the C-shaped guide rail is aligned with the cutting seam 2.

[0040] Then, according to the actual specifications such as width and thickness of the C-shaped guide rail to be cut, the telescopic control assembly is controlled to act through the control console 5, the distance between the two C-shaped mounting frames 7 is adjusted, and the conveying and abutting assembly can accurately fit the side wall of the C-shaped guide rail to form support. Specifically, the first cylinder 13 in the telescopic control assembly will receive the instruction and extend the output end upward, driving the piston block 14 fixed at the top to slide upward in the liquid collecting cavity 12 inside the positioning cross beam 6. The hydraulic oil in the liquid collecting cavity 12 will flow through the liquid guide channel 17 opened in the positioning cross beam 6 to the two limiting through holes 15 on the sides under the extrusion of the piston block 14. The hydraulic oil entering the limiting through hole 15 will respectively push the two piston rods 16 slidingly installed in the limiting through hole 15 on the sides, and one end of each piston rod 16 is fixed outside the C-shaped mounting frame 7. Therefore, the extension of the piston rod 16 will drive the two C-shaped mounting frames 7 on the sides to move horizontally away from the center of the positioning cross beam 6, until the driving belt 9 closely fits the two side walls of the C-shaped guide rail to form stable lateral support, avoiding the C-shaped guide rail from being offset or deformed due to stress during subsequent cutting.

[0041] Subsequently, the cutting stage is entered, the driving sliding table 3 at the top of the cutting table 1 is started by the control console 5, and the sliding block of the driving sliding table 3 will drive the cutting machine 4 fixed at the top to move smoothly along the length direction of the cutting seam 2. The cutting machine 4 starts the cutting function during the movement process to cut the C-shaped guide rail supported by the conveying and abutting assembly below. The cutting seam 2 provides a space for the cutting blade to avoid being damaged. During this process, the driving belt 9 on the two C-shaped mounting frames 7 always fits the side wall of the C-shaped guide rail, which on the one hand keeps the C-shaped guide rail from being horizontally displaced during cutting through the friction block 11, and on the other hand forms a supporting force that can offset the extrusion force of the cutting blade on the side wall of the C-shaped guide rail, fundamentally avoiding the bending and deformation of the side wall of the C-shaped guide rail.

[0042] Finally, when the C-shaped guide rail cutting is completed, the control console 5 first controls the cutting machine 4 to stop cutting and resets through the driving sliding table 3, then controls the output end of the first cylinder 13 to retract, driving the piston block 14 to slide downward in the liquid collecting cavity 12. A negative pressure is formed in the liquid collecting cavity 12, the hydraulic oil in the limiting through hole 15 will flow back to the liquid collecting cavity 12 through the liquid guide channel 17, and the piston rod 16 will retract and drive the C-shaped mounting frame 7 to reset. At the same time, the driving motor 10 continues to drive the driving belt 9 to rotate, conveying the C-shaped guide rail cut completed from above the cutting seam 2 out of the equipment, completing a complete C-shaped guide rail cutting operation cycle.

[0043] Example Two: Please refer to Figure 7 - Figure 10 The present embodiment further illustrates example one, and one side of each positioning cross beam 6 is provided with a correction assembly. The cutting table 1 is fixedly installed near one side of one of the positioning cross beams 6, and the top of the fixed plate 25 is provided with a cover support assembly.

[0044] The correcting assembly comprises an electric telescopic rod 18 and a double-sided rack 19. The electric telescopic rod 18 is vertically and fixedly installed outside one side of the positioning cross beam 6. The double-sided rack 19 is vertically and fixedly installed outside the output end of the electric telescopic rod 18. The positioning cross beam 6 is fixedly installed with a guide strip 34 on the side close to the double-sided rack 19. The double-sided rack 19 is vertically and slidingly and clampingly installed outside one side of the guide strip 34. The double-sided rack 19 is symmetrically and meshingly connected with two limiting gears 22. Each limiting gear 22 is provided with a rotating rod 21 on one side.

[0045] The rotating rod 21 is rotatably installed through the two ends. The rotating seat 20 is fixedly connected to the side of the positioning cross beam 6 close to the bottom end. The rotating rod 21 is rotatably installed through the middle of the limiting gear 22 on the corresponding side. The connecting plate 23 is fixedly installed on the bottom end of the rotating rod 21. The cylindrical rubber strip 24 is fixedly installed on the end of the connecting plate 23 away from the rotating rod 21.

[0046] The cover setting supporting assembly comprises a limiting groove 26 and a limiting rotating shaft 27. The limiting groove 26 is formed in the top end of the fixed plate 25. The limiting rotating shaft 27 is rotatably installed through the inside of one side edge of the limiting groove 26. The limiting rotating shaft 27 is fixedly installed through the end. The driving gear 28 is fixedly installed through the end of the limiting rotating shaft 27. The driving gear 28 is laterally and meshingly connected with the driving gear 30.

[0047] The second air cylinder 29 is fixedly installed on the side of the fixed plate 25 close to the driving gear 30 through the support. The output end of the second air cylinder 29 is fixedly connected with one side of the driving gear 30. The limiting rotating shaft 27 is fixedly installed with a rotating plate 31 on one side. The top end of the rotating plate 31 is provided with a placing groove 32. The plastic cover 33 is placed in the inside of the placing groove 32.

[0048] In this embodiment, the correcting assembly and the cover setting supporting assembly are added on the basis of the first embodiment to further strengthen the precision guarantee and subsequent protection during the cutting of the C-shaped guide rail. The working process connects the “C-shaped guide rail conveying, positioning and spacing regulation” link of the first embodiment. The specific principle is as follows:

[0049] Firstly, after the C-shaped guide rail has been conveyed to above the cutting slot 2 by the conveying interference assembly, and the telescopic adjustment assembly drives the C-shaped mounting frame 7 to form lateral support, the console 5 will simultaneously start the correction assembly outside one side of the positioning cross beam 6 to accurately correct and prevent deformation of the inner concave side wall of the opening end of the C-shaped guide rail. The action logic of the correction assembly is as follows: the console 5 sends instructions to the electric telescopic rod 18, and the output end of the electric telescopic rod 18 extends vertically downward, driving the double-sided rack 19 fixed at the top end to move downward synchronously. Since the positioning cross beam 6 is fixed on one side close to the double-sided rack 19, and the double-sided rack 19 is vertically slidingly engaged on the outside of the guide bar 34, the guide bar 34 can limit the movement direction of the double-sided rack 19, avoiding horizontal deviation during the downward and upward process, and ensuring stable meshing transmission.

[0050] As the double-sided rack 19 moves downward, the two limit gears 22 symmetrically engaged on both sides will be synchronously driven to rotate. The rotation of the limit gear 22 will drive the rotating rod 21 to rotate synchronously inside the rotating seat 20. When the rotating rod 21 rotates, the connecting plate 23 will drive the cylindrical rubber strip 24 to flip towards the inner concave side wall of the opening end of the C-shaped guide rail until the cylindrical rubber strip 24 tightly interferes with the inner concave side wall of the C-shaped guide rail.

[0051] Due to the synchronous rotation of the two limit gears 22 and the synchronous flipping of the connecting plate 23, the cylindrical rubber strips 24 on both sides will exert uniform interference expansion force on the inner concave side wall of the C-shaped guide rail, which can correct the slight verticality deviation of the C-shaped guide rail caused by previous processing or conveying, ensuring that the side wall remains vertical; on the other hand, it can further offset the extrusion force of the cutting blade on the side wall of the C-shaped guide rail during the subsequent cutting process, avoiding deformation of the slot, providing double protection for cutting accuracy and subsequent assembly (the cylindrical rubber strip 24 is made of elastic rubber material, which can provide support while avoiding scratching the inner wall of the C-shaped guide rail).

[0052] When the correction assembly completes the interference expansion and the cutting machine 4 completes the C-shaped guide rail cutting according to the process of embodiment one, the console 5 will start the cover setting support assembly to support and protect one end of the cut C-shaped guide rail, preventing the C-shaped guide rail from sagging and deforming due to the lack of constraint on one end during subsequent transportation or temporary storage. The working principle of the cover setting support assembly is as follows: the console 5 sends instructions to the second air cylinder 29, the output end of the second air cylinder 29 extends horizontally, driving the fixed driving rack 30 at the top to move synchronously, the movement of the driving rack 30 will drive the meshing driving gear 28 to rotate, in turn driving the fixed limiting shaft 27 of the driving gear 28 to rotate inside the limiting groove 26 on one side edge, when the limiting shaft 27 rotates, the rotating plate 31 will be flipped to one end of the C-shaped guide rail, the top of the rotating plate 31 is provided with a placing groove 32, and a plastic cover 33 is pre-placed in the placing groove 32, when the rotating plate 31 is flipped to align with the port of the C-shaped guide rail, the plastic cover 33 will be embedded into the inside of one end of the C-shaped guide rail under the pushing of the rotating plate 31, and the outer wall of the plastic cover 33 tightly fits with the inner wall of the C-shaped guide rail, forming stable internal support, which can effectively prevent the C-shaped guide rail from sagging or slightly deforming due to the lack of constraint on one end during transportation and temporary storage after cutting, at the same time, the material of the plastic cover 33 can avoid scratching the inner wall of the C-shaped guide rail, reserving an intact structure basis for the subsequent precise assembly with other parts of the sofa support, at the same time, an existing feeding device can be installed on one side of the cutting table 1 to transport and place the plastic cover 33.
