Here, the conveying direction of the spring 300 in the spring bagging conveying device 100 is a direction from the rear to the front as shown in fig. 1, and a lateral direction orthogonal to the conveying direction of the spring 300 is a left-right direction as shown in fig. 1.

In the description of the present invention, it is to be understood that the terms "front", "back", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, which are merely for convenience of description of the present invention and simplification of description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

The spring transfer conveying device 200 comprises a third endless conveying belt 201, a plurality of conveying seats 202 for positioning the springs 300 are arranged on the outer peripheral surface of the third endless conveying belt 201, and the plurality of conveying seats 202 are uniformly arranged at intervals along the circumferential direction of the third endless conveying belt 201. It is understood that the present invention is not limited to the form of conveying belt, for example, the spring transfer conveying device 200 may also be a conveying chain or a conveying wheel, and those skilled in the art can determine the conveying belt according to the actual requirement. Here, it is understood that "annular", for example, racetrack-shaped. In the description of the present invention, "a plurality" means at least two, e.g., two, three, etc., unless specifically limited otherwise.

Specifically, the conveying bases 202 are provided with magnetic members, the magnetic members can attract springs, each conveying base 202 can attract one spring 300 transmitted by the spring coiling machine, and conveying is completed under the action of the annular conveying belt 201. The magnetic adsorption mode is adopted, the structure is simple, and the transfer from the spring coiling machine and the transfer from the spring transfer conveying device 200 to the spring bagging conveying device 100 are simple and convenient. Further, the top surface of the conveying seat 202 is a curved surface adapted to the outer contour of the spring 300 and concaved toward the third endless conveyor belt 201, in other words, the bottom surface of the conveying seat 202 is connected to the outer circumferential surface of the third endless conveyor belt 201, the top surface of the conveying seat 202 is designed to be a surface curved toward the bottom surface of the conveying seat 202, and the curved surface is adapted to the outer contour of the spring 300 so as to fix the spring 300 on the conveying seat 202.

The spring bagging conveyor 100 includes a first endless conveyor belt 1 and a second endless conveyor belt 2, for example, the first endless conveyor belt 1 and the second endless conveyor belt 2 are timing belts. First endless conveyor belt 1 sets up around first band pulley 3, and second endless conveyor belt 2 sets up around second band pulley 4, all does not set up the baffle in first endless conveyor belt 1 and the second endless conveyor belt 2, and first endless conveyor belt 1 sets up and form spring transfer passage 5 between the two with second endless conveyor belt 2 is relative on horizontal, and the width of spring transfer passage 5 reduces along spring 300's direction of delivery gradually. It is understood that the spring conveying channel 5 extends in the conveying direction of the springs 300, and the width of the spring conveying channel 5 is the width in the transverse direction orthogonal to the conveying direction of the springs 300, and the width of the spring conveying channel 5 in the transverse direction is the distance between the first endless conveyor belt 1 and the second endless conveyor belt 2 in the transverse direction, and the distance between the first endless conveyor belt 1 and the second endless conveyor belt 2 in the transverse direction gradually decreases in the conveying direction of the springs 300.

Here, neither the first endless conveyor belt 1 nor the second endless conveyor belt 2 is provided with a baffle, which means that the first endless conveyor belt 1 and the second endless conveyor belt 2 are not provided around the baffle, so that in the process of gradually compressing and conveying the spring, sliding friction between the first and second endless conveyor belts and the baffle does not occur to cause abrasion of the first endless conveyor belt 1 and the second endless conveyor belt 2 and the baffle. In addition, since no baffle is provided, the side of the first endless conveyor belt 1 and the second endless conveyor belt 2 that grips the spring can be deformed inward, thereby providing cushioning to the spring to allow the spring to be gradually compressed and conveyed to be axially expanded by a certain amount, whereby the spring is not easily arched. Therefore, in the present invention, the first endless conveyor belt 1 and the second endless conveyor belt 2 may also be referred to as "endless conveyor belts without baffles".

In other words, the endless conveyor belt is called a "baffled endless conveyor belt" as long as the conveyor belt is provided with components that generate sliding friction with the conveyor belt and prevent the springs from axially expanding and deforming during the gradual compression and conveyance of the springs. Of course, the baffle is to be understood broadly herein and may for example comprise an annular plate, or one or more straight sections of plate, which may also be part of the frame. For example, the conveyor belt disclosed in document CN103879604A is disposed around a baffle, i.e., a baffle is disposed in the conveyor belt, and the conveyor belt is a "baffled endless conveyor belt".

Further, the included angle between the first endless conveyor belt 1 and the second endless conveyor belt 2 is adjustable. It can be understood that the spring bagging conveying device can be suitable for springs of different types by adjusting the included angle, and the applicability of the spring bagging conveying device is improved.
