[0043] Reference Figure 1 and Figure 4 According to an embodiment of the present invention, a spring conveying device includes a compression mechanism 100, a conveying mechanism 200, and a limiting mechanism 300.

[0044] The compression mechanism 100 comprises a first conveying belt 110 and a second conveying belt 120 symmetrically arranged, the first conveying belt 110 and the second conveying belt 120 are arranged in a V shape and at least a part of the first conveying belt 110 and the second conveying belt 120 are arranged in a V shape, so that the gap between the first conveying belt 110 and the second conveying belt 120 forms a conveying channel with a wide end 130 and a narrow end 140 and is used for compressing the conveying spring a, that is, a funnel-shaped conveying channel, the spring a is conveyed from the wide end 130 of the conveying channel to the narrow end 140 to realize the compression conveying of the spring a, the conveying mechanism 200 is located above the compression mechanism 100 and can convey the spring a to the compression mechanism 100, the conveying mechanism 200 comprises a first closed annular conveying member 210, specifically, the first closed annular conveying member 210 can be a chain or a conveying belt, which is not limited here, a plurality of magnetic bases 220 for adsorbing and fixing the spring a are arranged on the first closed annular conveying member 210, the plurality of magnetic bases 220 are uniformly and spacedly arranged along the conveying path of the first closed annular conveying member 210, and the conveying path of the lower part of the first closed annular conveying member 210 can cover at least the conveying channel, the limiting mechanism 300 is located below the compression mechanism 100, and the limiting mechanism 300 is used in cooperation with the conveying mechanism 200 to limit the arching of the spring a during the compression conveying.

[0045] The spring a is limited by the limiting mechanism 300 during the compression conveying of the spring a, which is beneficial to prevent the spring a from arching during the compression conveying, thereby preventing the spring a from falling off during the compression conveying. Specifically, the spring a is conveyed to the compression mechanism 100 by the conveying mechanism 200 and enters the conveying channel to start compression conveying, at this time, the spring a does not separate from the magnetic base 220, that is, the spring a is always limited by the magnetic base 220 and the limiting mechanism 300 during the compression conveying, until the spring a is compressed, the magnetic base 220 and the limiting mechanism 300 are separated from the spring a after the compression, so as to facilitate the spring a after the compression to be loaded into the non-woven fabric bag.

[0046] Referring to Figure 1 , Figure 5 , Figure 6 , Figure 11 and Figure 12In some embodiments, the limiting mechanism 300 comprises a second ring-shaped conveying member 310 in the form of a closed loop. Specifically, the second ring-shaped conveying member 310 can be a chain or a conveying belt, which is not limited herein. The conveying speed of the second ring-shaped conveying member 310 is the same as that of the first ring-shaped conveying member 210. A plurality of limiting members 320 corresponding to the plurality of magnetic bases 220 are arranged on the second ring-shaped conveying member 310 along the conveying path thereof. The conveying path of the upper portion of the second ring-shaped conveying member 310 can cover the conveying channel described above, so that the stroke of the limiting member 320 can cover at least the stroke of the spring a during compression conveying. Thus, the limiting member 320 can cooperate with the corresponding magnetic base 220 and limit the spring a from arching in the vertical direction during compression conveying. Specifically, during compression conveying of the spring a, the spring a is clamped between the magnetic base 220 and the limiting member 320, so as to limit the spring a from arching in the vertical direction, thereby preventing the spring a from falling off during compression conveying.

[0047] Referring to Figures 5 to 10 In some embodiments, the limiting mechanism 300 further comprises a limiting baffle 330 vertically arranged at the middle portion of the limiting member 320. Specifically, the limiting baffle 330 is arranged at the middle portion. The limiting baffle 330 can limit the spring a from arching backward in the conveying direction during compression conveying. During compression conveying of the spring a, when the limiting member 320 is in abutment with the magnetic base 220, the limiting baffle 330 on the limiting member 320 can be inserted into the middle portion of the spring a fixedly adsorbed on the magnetic base 220. When the limiting member 320 advances forward along the conveying direction of the spring a, the limiting baffle 330 can apply a forward driving force to the spring a, thereby assisting the spring a to advance forward in the conveying direction and preventing the spring a from arching backward in the conveying direction, thereby preventing the spring a from falling off during compression conveying.

[0048] Referring to Figures 11 to 14 In some other embodiments, the limiting baffle 330 is vertically arranged at the middle portion of the magnetic base 220. Specifically, the limiting baffle 330 is arranged at the middle portion and is inserted into the middle portion of the spring a. During compression conveying of the spring a, when the magnetic base 220 advances forward along the conveying direction of the spring a, the limiting baffle 330 can apply a forward driving force to the spring a, thereby assisting the spring a to advance forward in the conveying direction and preventing the spring a from arching backward in the conveying direction, thereby preventing the spring a from falling off during compression conveying.

[0049] It should be noted that in some other embodiments, the limiting baffle can also be arranged on the side of the limiting piece or the magnetic base and used to block the side of the spring a. During the compression and conveying of the spring a, the limiting baffle blocking the side of the spring a can limit the spring a from arching backward in the conveying direction of the spring a, thereby facilitating the prevention of the spring a from falling off during the compression and conveying.

[0050] It should be noted that in some embodiments, the limiting piece 320 is a magnetic piece, so that the limiting piece 320 has the effect of adsorbing and fixing the spring a, thereby facilitating the further prevention of the spring a from arching during the compression and conveying, and thereby facilitating the further prevention of the spring a from falling off during the compression and conveying.

[0051] Referring to Figure 2 , Figure 13 and Figure 14 , in some embodiments, the magnetic base 220 is provided with a first limiting groove 221 for limiting. Specifically, the first limiting groove 221 is a V-shaped groove, and the first limiting groove 221 can limit the spring a from moving forward and backward relative to the magnetic base 220, thereby facilitating the prevention of the spring a from arching forward or backward during the compression and conveying, and thereby facilitating the prevention of the spring a from falling off during the compression and conveying. Figure 3 In some other embodiments, the first limiting groove is an arc-shaped groove. Of course, the first limiting groove can also have other shapes that can limit, which are not limited herein.

[0052] Referring to Figure 2 , Figure 11 and Figure 12 , in some embodiments, the limiting piece 320 is provided with a second limiting groove 321 for limiting. Specifically, the second limiting groove 321 is a V-shaped groove, and the second limiting groove 321 can limit the spring a from moving forward and backward relative to the limiting piece 320, thereby facilitating the prevention of the spring a from arching forward or backward during the compression and conveying, and thereby facilitating the prevention of the spring a from falling off during the compression and conveying. Figure 3In some other embodiments, the second limiting groove is an arc-shaped groove, and the second limiting groove can also be other shapes capable of limiting, which are not limited herein. When the magnetic base 220 is in abutment with the limiting piece 320, at least part of the upper portion of the spring a is embedded in the first limiting groove 221, and at least part of the lower portion of the spring a is embedded in the second limiting groove 321, that is, the minimum distance between the magnetic base 220 and the limiting piece 320 is less than the waist diameter of the spring a, so that the spring a clamped between the magnetic base 220 and the limiting piece 320 can be simultaneously limited in the up, down, front and back directions during the compression conveying process, thereby facilitating the prevention of the spring a from arching upward or downward in the vertical direction during the compression conveying process and facilitating the prevention of the spring a from arching forward or backward in the conveying direction during the compression conveying process. In addition, the minimum distance between the magnetic base 220 and the limiting piece 320 is slightly greater than the width of the first conveying belt 110 and the second conveying belt 120, so that the magnetic base 220 and the limiting piece 320 will not interfere with the first conveying belt 110 and the second conveying belt 120 during the compression conveying of the spring a.

[0053] Referring to Figure 15 In some other embodiments, the limiting mechanism 300 comprises an annular conveying belt 340, and the supporting area of the upper portion of the annular conveying belt 340 can cover at least the conveying channel, so that the supporting area of the upper portion of the annular conveying belt 340 can support at least the spring a located in the conveying channel for compression conveying, so that the annular conveying belt 340 can cooperate with the magnetic base 220 and at least limit the spring a from arching in the vertical direction during the compression conveying process. During the compression conveying of the spring a, the spring a is clamped between the magnetic base 220 and the supporting area of the upper portion of the annular conveying belt 340, so that the spring a can be limited from arching in the vertical direction, thereby facilitating the prevention of the spring a from falling off during the compression conveying process, and the structure is simple and easy to implement.

[0054] Referring to Figure 16 In some other embodiments, the limiting mechanism 300 comprises a supporting plate 350, and the supporting area of the supporting plate 350 can cover at least the conveying channel, so that the supporting area of the supporting plate 350 can support at least the spring a located in the conveying channel for compression conveying, so that the supporting plate 350 can cooperate with the magnetic base 220 and at least limit the spring a from arching in the vertical direction during the compression conveying process. During the compression conveying of the spring a, the spring a is clamped between the magnetic base 220 and the supporting area of the supporting plate 350, so that the spring a can be limited from arching in the vertical direction, thereby facilitating the prevention of the spring a from falling off during the compression conveying process, and the structure is simple and easy to implement.

[0055] It should be noted that in some other embodiments, the limiting mechanism 300 comprises a roller assembly (not shown in the figure), which comprises a plurality of rotatable rollers for supporting the spring a, and the supporting area of the upper part of the roller assembly can cover at least the conveying channel, so that the supporting area of the upper part of the roller assembly can support at least the spring a in the conveying channel for compression conveying, so that the roller assembly can cooperate with the magnetic base 220 and at least limit the spring a from arching in the vertical direction during compression conveying, and the spring a is clamped between the magnetic base 220 and the supporting area of the upper part of the roller assembly during compression conveying of the spring a, so as to limit the spring a from arching in the vertical direction, thereby facilitating the prevention of the spring a from falling off during compression conveying, and the structure is simple and easy to implement.
