Detailed Implementation

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0049] See Figures 1 to 10 As shown, a bag spring processing device includes a support frame 1, with two spring processing structures 2 fixed at one end of the support frame. The support frame is equipped with two spring receiving structures 8 that cooperate with the two spring processing structures, and two double-belt spring conveying structures 3 that cooperate with the two spring receiving structures. The support frame also includes a face fabric feeding structure 4 and a bottom fabric feeding structure 5. The spring processing structures are mainly used to process the fed wire into springs. The spring receiving structures receive the processed springs and gradually compress them to a certain height before feeding them into the double-belt spring conveying structures. The face fabric feeding structure and the bottom fabric feeding structure are used for conveying the fabric and wrapping it after the spring is fed in. The fabric is then welded using a fabric welding structure to position the spring and complete the processing. This method improves processing efficiency and is highly practical.

[0050] In practical applications, the bracket is equipped with a main push spring structure 7 and a finished product pull-out structure 6; and the bracket is equipped with a fabric welding structure 9. The main push spring structure is mainly used to push the spring to the corresponding position, ensuring that the spring is in the fabric, improving processing accuracy, and also improving processing efficiency. The finished product pull-out structure is mainly used for the finished products to be collected and pulled out after processing. It is mainly realized by the active roller, the driven roller, the guide roller and the corresponding motor structure. This is a conventional structure in the prior art, so it is not described in detail.

[0051] During operation, the spring is gradually compressed to a certain height after passing through the spring receiving structure. The compressed spring is then pushed by the spring pusher into the double-belt spring conveyor structure, which delivers the compressed spring between the face fabric feeding structure and the back fabric feeding structure. Because the spring is already compressed to a certain height upon entering the double-belt spring conveyor structure, there is no need for further spring compression before the main spring pusher structure pushes the spring, thus saving the spring compression step and improving processing efficiency.

[0052] In practical applications, the spring processing structure is used to process the fed iron wire into finished springs; the double-belt spring conveying structure is used to feed the compressed springs between the face fabric feeding structure and the bottom fabric feeding structure; the main push spring structure is used to push the compressed springs between the face fabric feeding structure and the bottom fabric feeding structure; and the fabric welding structure is used to weld and position the fabric fed with the springs, and then pull them out through the finished product pull-out structure. These structural steps improve processing efficiency and ensure smooth and effective processing.

[0053] In practical applications, the dual-belt spring conveying structure includes a mounting plate 31, a drive motor 32, several belt-linked pulleys 33, several drive wheels 34, an upper belt 35, and a lower belt 36. During assembly, the drive motor is fixed to one of the belt-linked pulleys, and the several belt-linked pulleys are connected by a linkage belt 37. The drive wheels are connected to the belt-linked pulleys respectively, and the upper and lower belts are connected to the drive wheels to achieve transmission. The output end of the spring processing structure cooperates with the input end of the spring receiving structure, and the end of the dual-belt spring conveying structure cooperates with the output end of the spring receiving structure, conveying the springs compressed by the spring receiving structure to the fabric feeding structure and the bottom fabric feeding structure. In this embodiment, the upper and lower belts are stacked vertically. The synchronous transmission of the upper and lower belts is achieved through a single drive motor, which improves the smoothness and effectiveness of spring conveying and also increases conveying efficiency. Furthermore, the cooperation between the upper and lower belts better clamps the springs, thereby improving conveying accuracy and saving conveying time, making it highly practical.

[0054] In this embodiment, there are two double-belt spring conveying structures, each connected to a separate spring receiving structure. The tail of one double-belt spring conveying structure is aligned side-by-side with the front of the other double-belt spring conveying structure. A push-spring assembly pushes the spring from one double-belt spring conveying structure onto the other, ensuring all springs are conveyed in a straight line, thereby improving the conveying efficiency. In this embodiment, the push-spring assembly is identical to the push-spring device structure.

[0055] In practical applications, the total push spring structure includes a slider mounting plate 71, a guide rail slider 72, a push spring plate 73, a rack 74, a gear 75, a transmission shaft 76, and a control motor 77. In this embodiment, there are two racks arranged parallel to each other, and two gears are respectively located on the racks. The gears are fixed at both ends of the transmission shaft. The control motor can drive the two gears through the transmission shaft. During assembly, the slider mounting plate is fixed on the bracket, and the rack can be translatably mounted on the slider mounting plate through the guide rail slider. The gear is mounted on the rack and meshes with it. The transmission shaft is mounted on the frame through bearings. The push spring plate is fixed to the end of the rack. The control motor drives the transmission shaft and drives the gear to rotate. The gear drives the rack to translate and causes the push spring plate to translate, thus achieving the spring push.

[0056] In this embodiment, a spring receiving structure 8 is provided between the spring processing structure and the double-belt spring conveying structure. The spring receiving structure mainly facilitates the smooth transfer of the springs from the spring processing structure to the double-belt spring conveying structure, thus completing the transfer.

[0057] In practical applications, the spring receiving structure includes a spring receiver 81 and a spring pusher 82 connected to the output end of the spring receiver. The output end of the spring processing structure is connected to the spring receiver, and the output end of the spring pusher is connected to the input end of the double-belt spring conveying structure. Furthermore, the spring pusher includes a spring pusher mounting plate 821, a pusher motor 822, a crankshaft 823, a connecting rod 824, a guide rail slider 825, and a spring pusher block 826. During assembly, the spring pusher mounting plate is fixed to a bracket, the pusher motor is fixed to one end of the spring pusher mounting plate, and the crankshaft is connected to the main shaft of the pusher motor. The connecting rod connects the crankshaft and the guide rail slider. The spring pusher block 826 is fixed to the tail of the guide rail slider, and the guide rail slider moves horizontally on the spring pusher block under the action of the connecting rod to push the spring. The push motor converts rotational force into horizontal thrust through the connecting rod by rotating the crankshaft, and pushes the spring on the push spring plate onto the double belt spring conveyor structure through the guide rail slider;

[0058] Furthermore, the spring receiver includes a spring compression plate 811, a cam mounting plate 812, a micro motor 813, a cam 814, a brush 815, a spring receiving turntable 816, a spring receiving optical shaft 817, a divider, and a spring receiving motor. During assembly, the spring compression plate is fixed to a bracket, the cam mounting plate is fixed to the spring compression plate, and the cam is mounted on the cam mounting plate. The spring receiving optical shafts are evenly spaced on the spring receiving turntable, which is mounted on the divider. The divider is mounted on a frame and connected to the spring receiving motor. The micro motor is fixed to the cam mounting plate, and a brush is fixed to the main shaft of the micro motor. The spring receiving optical shaft receives the spring. During use, the finished spring is fitted onto the spring receiving optical shaft and rotates with the spring receiving turntable under the action of the cam. It then enters the spring compression plate to compress the spring and detach it from the spring receiving optical shaft. After compression, the spring enters the spring pusher. The brush is mainly used to clean the spring receiving optical shaft, preventing impurities from affecting its normal operation. In practical applications, a spring-connecting motor is fixed on its cam mounting plate to connect with the spring-connecting turntable to achieve its rotation drive. It can also be equipped with a divider for dividing operations to ensure the effectiveness and stability of the spring connection.

[0059] In practical applications, the fabric welding structure 9 includes a cylinder mounting plate 91, a transverse cylinder 92, a longitudinal cylinder 93, a longitudinal welding knife mounting plate 94, a transverse welding knife mounting plate 95, a longitudinal welding knife 96, a transverse welding knife 97, an ultrasonic base 98, and an ultrasonic welder 99. During assembly, the cylinder mounting plate is fixed to a bracket; the transverse cylinder is fixed to the side of the cylinder mounting plate; the transverse welding knife mounting plate is fixed to the piston shaft fixing plate of the transverse cylinder, and the transverse welding knife is fixed to the bottom of the transverse welding knife mounting plate; the longitudinal welding knife mounting plate is located at the bottom of the cylinder mounting plate, the longitudinal cylinder is located at the bottom of the cylinder mounting plate, and the longitudinal welding knife mounting plate is installed below the piston shaft fixing plate of the longitudinal cylinder, and the longitudinal welding knife is fixed to the bottom of the longitudinal welding knife mounting plate; the ultrasonic base is fixed to a bracket; the welder body is mounted on the ultrasonic base and is directly below the positions of the longitudinal and transverse welding knives, and the welding surface of the welder body can just accommodate the transverse and longitudinal welding knives, for completing the welding operation of the bottom fabric. The ultrasonic welding head features a close proximity between its transverse and longitudinal welding blades, and its wide welding surface perfectly accommodates both blades. This eliminates the need to move the blades, allowing for welding of the bottom surface fabric, thus saving costs and improving production efficiency. The ultrasonic welder is fixed to the top of the ultrasonic base and directly below the longitudinal and transverse welding blades for welding operations. This design enhances welding efficiency and stability, and the blade positions can be adjusted and controlled using only the longitudinal and transverse cylinders.

[0060] This utility model has positive effects: its structure is reasonably designed, featuring two spring processing structures, a double-belt spring conveying structure, a main push spring structure, and a fabric welding structure. This facilitates the rapid processing, conveying, and assembly of springs with fabric, as well as welding positioning, thereby improving processing accuracy and efficiency. Furthermore, the double-belt spring conveying structure provides better clamping and fixing, saving conveying time and increasing conveying efficiency. The main push spring structure ensures rapid and effective spring pushing, guaranteeing accurate spring positioning, improving processing efficiency, and providing stable and reliable operation with strong practicality.

[0061] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0062] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
