Description

Technical Field

[0001] The present invention relates to a compression and conveying device for bagged springs, belonging to the technical field of bagged spring processing equipment. Background Art

[0002] The manufacturing of bagged springs usually involves first winding springs by a spring winding machine, then conveying the springs to a compression mechanism through a spring conveying mechanism for compression. After being compressed to a certain extent, they are conveyed to a bagging mechanism, and the bagging mechanism wraps and seals each adjacent spring front and back with cloth to form a bagged spring string. The prior art "Application No.: 2014100791737" discloses a compression and conveying mechanism for bagged springs, which discloses the compression and conveying mechanism of bagged springs, that is, "the spring compression and conveying mechanism includes two pairs of baffles arranged on a frame and a conveyor belt wound around the outside of the baffles. The distance between the two baffles gradually decreases from one end to the other end. The spring conveying mechanism conveys the spring between the two baffles and drives the spring to move so that the spring moves from the end with a larger distance between the two baffles to the other end with a smaller distance between the two baffles. When the spring moves horizontally, it is gradually compressed as the distance between the two baffles gradually decreases. After the spring is compressed to a certain extent, it disengages from the spring conveying mechanism and is conveyed by the spring compression and conveying mechanism."

[0003] The above technology has the following defects: Since the spring is not fully cooled after coming out of the spring winding machine and has poor resistance to deformation, when the spring is compressed while moving between the two baffles, it will be affected by the forward acting force of the conveyor belt outside the baffles, resulting in the two ends of the spring being prone to bending forward, affecting the product quality.

[0004] Therefore, how to provide a compression and conveying device that can not only achieve rapid compression of the spring but also avoid bending and deformation of the spring is the research objective of the present invention. Summary of the Invention

[0005] Aiming at the deficiencies of the above technology, the present invention provides a compression and conveying device for bagged springs, which quickly compresses the springs sent by the spring conveying mechanism through opening and closing compression plates, avoiding bending and deformation of the springs. After compression is completed, it is continuously conveyed to the bagging mechanism through a conveying chain for bagging.

[0006] To solve the problems of the prior art, the technical solution adopted by the present invention is:

[0007] A compression and conveying device for bagged springs, characterized in that: it includes a conveying mechanism and a compression and conveying mechanism. The compression and conveying mechanism is arranged at the discharge end of the conveying mechanism to receive the springs conveyed by the conveying mechanism and compress them. The compression and conveying mechanism includes a compression plate installed on a slide rail, and two groups of oppositely arranged long conveying chains and short conveying chains. Chain guides are arranged on the outer sides of the long conveying chains and the short conveying chains. The compression plate is arranged at the feeding end of the short conveying chain and on the opposite side of the long conveying chain. One side of the compression plate is connected by a crank and connecting rod to a reduction motor that drives it to open and close. A compression and conveying chain is arranged around the outer side of the compression plate.

[0008] Further, the long conveying chain and the short conveying chain are respectively installed on the slide rail through a bottom plate, and a left - hand and right - hand threaded screw is used to adjust the distance between the long conveying chain and the short conveying chain. One end of the left - hand and right - hand threaded screw is provided with an adjusting handwheel.

[0009] Further, the reduction motor is installed on the slide rail where the compression plate is located through a motor base, and the motor base is connected to the bottom plate of the short conveying chain through a connecting plate.

[0010] Further, a spring - withdrawing plate is arranged above the long conveying chain and the short conveying chain, and the spring - withdrawing plate is located at one end of the compression plate away from the conveying mechanism.

[0011] Further, one end of the long conveying chain extends obliquely outward to the lower part of the discharge end of the conveying mechanism.

[0012] Further, the long conveying chain, the short conveying chain, and the compression and conveying chain are respectively driven by independent servo motors to operate.

[0013] Further, the conveying mechanism is set as a vertical "E" - shaped structure, and a cooling air duct is arranged at its bottom. One end of the cooling air duct is connected with a cooling fan.

[0014] The beneficial effects of the present invention are: 1. The springs conveyed by the spring conveying mechanism are quickly compressed by the opening and closing compression plate, avoiding the bending deformation of the springs and ensuring the product quality; 2. The distance between the long conveying chain and the short conveying chain is adjustable, capable of adapting to the compression and conveying of springs with different lengths; 3. The spring - withdrawing plate holds the spring to make it fall off from the magnetic - attachment plate, ensuring that the spring can be smoothly transferred from the conveying mechanism to the compression and conveying mechanism; 4. The conveying mechanism is set as a vertical "E" - shape, prolonging the conveying time of the spring on the conveying mechanism and enabling the spring to have sufficient time for heat dissipation; 5. The cooling fan is used to perform air - cooling heat dissipation on the springs on the conveying mechanism, improving the cooling speed and effect of the springs. Description of the Drawings

Detailed implementation manners

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the following Figure 1-8 makes a further analysis of the present invention in conjunction with the appended

[0025] Such as Figure 1-8As shown, a compression and conveying device for bagged springs is characterized in that it includes a conveying mechanism 10 and a compression and conveying mechanism 20, wherein the compression and conveying mechanism 20 is arranged at the discharge end of the conveying mechanism 10 to receive the springs conveyed by the conveying mechanism 10 and compress them; the compression and conveying mechanism 20 includes a compression plate 201 installed on a slide rail, and two sets of long conveying chains 202 and short conveying chains 203 arranged opposite to each other; chain guides 204 are arranged on the outer sides of the long conveying chains 202 and the short conveying chains 203; the compression plate 201 is arranged at the feeding end of the short conveying chain 203 and is located on the opposite side of the long conveying chain 202; one side of the compression plate 201 is connected to a reduction motor 206 for driving its opening and closing through a crank connecting rod 205; a compression and conveying chain 207 is arranged around the outer side of the compression plate 201.

[0026] In this embodiment, preferably, the long conveying chain 202 and the short conveying chain 203 are respectively installed on the slide rail through a base plate 208, and the distance between the long conveying chain 202 and the short conveying chain 203 is adjusted by a positive and negative thread screw 209, the positive end of the positive and negative thread screw 209 is connected to the base plate of the long conveying chain 202 through a nut seat, and the negative end of the positive and negative thread screw 209 is connected to the base plate of the short conveying chain 203 through a nut seat; one end of the positive and negative thread screw 209 is provided with an adjusting hand wheel 210, and the distance between the long conveying chain 202 and the short conveying chain 203 is adjusted by rotating the positive and negative thread screw 209 through the adjusting hand wheel 201.

[0027] In this embodiment, preferably, the reduction motor 206 is installed on the slide rail where the compression plate 201 is located through a motor seat 211, and the motor seat 211 is connected to the bottom plate of the short conveying chain 203 through a connecting plate 212. When the position of the short conveying chain 203 moves, the motor seat 211 will be driven to move synchronously through the connecting plate 212, so that the compression plate 201 and the short conveying chain 203 keep moving synchronously, ensuring that the starting position of the compression plate 201 is level with the short conveying chain 203.

[0028] In this embodiment, preferably, a spring release plate 213 is provided above the long conveying chain 202 and the short conveying chain 203. The spring release plate 213 is located at the end of the compression plate 201 away from the conveying mechanism 10. The spring is clamped by the spring release plate 213 to make it fall off the magnetic attachment plate, thereby ensuring that the spring can be smoothly transferred from the conveying mechanism 10 to the compression conveying mechanism 20.

[0029] In this embodiment, preferably, one end of the long conveying chain 202 extends outwardly at an angle to below the discharge end of the conveying mechanism 10 , so as to guide the spring of the conveying mechanism 10 to enter the compression conveying mechanism 20 in the center.

[0030] In this embodiment, preferably, the long conveying chain 202, the short conveying chain 203 and the compression conveying chain 207 are respectively driven by independent servo motors.

[0032] When the present invention is in use: manually adjust the distance between the long conveying chain 202 and the short conveying chain 203 according to the length of the spring to be compressed. After the spring comes out of the spring coiling machine, it is attracted by the magnetic - attachment plate of the conveying mechanism 10 and conveyed to the discharge end of the conveying mechanism 10. At this time, the compression plate 201 is in an open state driven by the reduction motor 206 (that is, the reduction motor 206 drives the compression plate 201 to move away from the side of the long conveying chain 202). When the spring enters the working position of the compression plate 201 (the position of the spring is sensed by an externally - provided proximity switch and the start - stop of the reduction motor 206 is controlled by a PLC control program), the reduction motor 206 drives the compression plate 201 to close (that is, the reduction motor 206 drives the compression plate 201 to move towards the long conveying chain 202 direction and stops at the position where the compression plate 201 is flush with the short conveying chain 203), and quickly compresses the spring. After the compression is completed, the spring is conveyed forward by the cooperation of the long conveying chain 202 and the compression conveying chain 207. After entering the short conveying chain 203, the spring is conveyed to the bagging mechanism by the cooperation of the short conveying chain 203 and the long conveying chain 202.
