Description

Technical Field

[0001] The utility model belongs to the technical field of bagged spring equipment, and in particular relates to a special welding device. Background Art

[0002] When the spring strip is produced, a plurality of springs are first loaded into a non-woven bag, and then the non-woven bag is sealed and welded, so that the springs in the bag are sealed in independent bag chambers to form a row of continuous bag spring strips.

[0003] However, currently, only a sealing knife with a single row of welding teeth is used to weld the cloth bags between adjacent springs, that is, a single row of welds is formed, which results in insufficient structural stability of the finished spring strip, and the spring strip is easily damaged by external forces and ruptured.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0014] The spring compression conveying mechanism adopts a V-shaped spring compression conveying mechanism; a V-shaped conveying belt is arranged on one side of the first welding mechanism.

[0015] The cloth folding mechanism comprises a cloth folding plate or a cloth folding rod.

[0016] The beneficial effects of the utility model are as follows:

[0023] The utility model is further described below in conjunction with specific implementation methods.

[0024] In the following description, all concepts related to directionality (or orientation) such as up, down, left, right, front and back are with reference to the position state of the figure being described, and are intended to facilitate public understanding. Therefore, they should not be understood as special limitations on the technical solution provided by the utility model.

[0025] like Figure 1-Figure 3 As shown, a special welding device includes a cloth folding mechanism 9, a spring compression conveying mechanism 1, a first welding mechanism 2 and a second welding mechanism 5; the cloth folding mechanism 9 is used to fold the cloth from the bottom to the top to form a structure of a cloth bag 3, and the cloth bag 3 is wrapped on the spring compression conveying mechanism 1; the spring compression conveying mechanism 1 is used to compress the spring 4 and convey the compressed spring 4 into the cloth bag 3; the first welding mechanism 2 is used to weld the cloth between two adjacent springs 4 in the cloth bag 3, and the first welding mechanism 2 is used to drive the spring bar 8 to move to the left; the second welding mechanism 5 is used to weld the opening of the cloth bag 3; the first welding mechanism 2 includes a first ultrasonic die head 21 and a first sealing knife 22 that are close to or far away from each other, and the welding teeth 6 in the first sealing knife 22 are in a parallel multi-row structure. Specifically, as Figure 4 As shown, the welding teeth 6 in the first sealing knife 22 are arranged in two parallel rows.

[0026] The second welding mechanism 5 includes a second ultrasonic die head 51 and a second sealing knife 52 that are close to or far away from each other, and the second ultrasonic die head 51 and the second sealing knife 52 are close to each other to weld the opening of the cloth bag 3. The welding teeth 6 of the second sealing knife 52 are in a single row structure. The second welding mechanism 5 is arranged above the spring compression conveying mechanism 1, and the second ultrasonic die head 51 and the second sealing knife 52 are close to or far away from each other in the horizontal direction (front and back direction). Both sides of the second welding mechanism 5 are provided with a cloth clamping roller assembly, and the cloth clamping roller assembly includes two cloth clamping rollers 10 arranged opposite to each other.

[0027] The first welding mechanism 2 is arranged at the front end of the spring 4 compression conveying mechanism 1, and the first ultrasonic die head 21 and the first sealing knife 22 are close to or away from each other in the vertical direction (up and down direction). The first welding mechanism 2 can translate or swing in the horizontal direction (left and right direction) to drive the spring bar 8 to move to the left. The spring compression conveying mechanism 1 adopts a V-shaped spring compression conveying mechanism; a V-shaped conveyor belt 11 is provided on one side (left side) of the first welding mechanism 2. The cloth folding mechanism 9 includes a cloth folding plate or a cloth folding rod (a cloth folding rod is used in the figure).

[0028] A special spring strip 8 is manufactured by a special welding device disclosed in the present application, comprising a spring 4 and a cloth for wrapping the spring 4, wherein the cloth wrapped with the spring 4 forms a cloth bag 3 structure, and the opening of the cloth bag 3 and the cloth between two adjacent springs 4 are welded by the first welding mechanism 2 and the second welding mechanism 5 mentioned above. The spring 4 is compressed and conveyed by a V-shaped spring compression conveying mechanism; the cloth is folded upward from the bottom by a cloth folding mechanism 9 to form a cloth bag 3 and wrapped on the V-shaped spring compression conveying mechanism. Finally, a double row of welds 7 are formed on the cloth between two adjacent springs 4 in the manufactured spring strip 8.

[0029] The present application welds the cloth bag 3 wrapped with the spring 4 by using the first welding mechanism 2 (vertical sealing mechanism) and the second welding mechanism 5 (horizontal sealing mechanism), wherein the welding teeth 6 in the first sealing knife 22 are arranged in multiple rows in parallel, that is, there are at least two rows of welds 7 formed on the cloth between two adjacent springs 4. At the same time, the second welding mechanism 5 is used to weld the opening of the cloth bag 3.
