DETAILED DESCRIPTION

[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 pocket spring sewing device includes a spring strip pulling mechanism 1, a first sewing mechanism 2, a second sewing mechanism 3 and a third sewing mechanism 4. The spring strip pulling mechanism 1 is used to drive the spring strip 5 to move horizontally (left and right); the first sewing mechanism 2 and the second sewing mechanism 3 move along the vertical (up and down) direction to sew the vertical sewing line 7; the first sewing mechanism 2 and the second sewing mechanism 3 cooperate with the spring strip pulling mechanism 1 to sew the transverse sewing line 6; the third sewing mechanism 4 is fixedly set at the cloth bag opening 142, and cooperates with the spring strip pulling mechanism 1 to sew the transverse sewing line 6 to sew the cloth bag opening 142 closed. A trimming assembly 9 is provided on one side of the third sewing mechanism 4.

[0026] The vertical movement directions of the first sewing mechanism 2 and the second sewing mechanism 3 are the same or opposite. The first sewing mechanism 2, the second sewing mechanism 3 and the third sewing mechanism 4 are used to sew the first sewing line 16, the second sewing line 17 and the third sewing line 18 respectively, and the first sewing line 16, the second sewing line 17 and the third sewing line 18 are all continuous structures (such as Figure 2 , Figure 4 and Figure 5 As shown, the first sewing line 16 and the second sewing line 17 both include a continuous transverse sewing line 6 and a vertical sewing line 7, and the third sewing line 18 is a continuous transverse sewing line 6; however, Figure 1 The first sewing line 16 and the second sewing line 17 are intermittent transverse sewing lines 6 and vertical sewing lines 7, and the third sewing line 18 is a continuous transverse sewing line 6).

[0027] The pocket spring sewing device includes a plurality of upper pressing plates 10 and lower pressing plates 11 arranged opposite to each other, and the upper pressing plates 10 and the lower pressing plates 11 are arranged in cooperation to compress the springs 12. The pocket spring sewing device also includes a spring push rod 13, which is used to push down the springs 12 and extend the vertically compressed springs 12 laterally to fill the cloth bags 14 to form spring strips 5.

[0028] The cloth bag 14 includes a cloth bag folding portion 141, and a fourth sewing mechanism is provided at the cloth bag folding portion 141. The first sewing mechanism 2, the second sewing mechanism 3 and the third sewing mechanism 4 are provided with a pressing piece 15, and the pressing piece 15 is used to limit the jumping of the cloth bag 14 when the first sewing mechanism 2, the second sewing mechanism 3 and the third sewing mechanism 4 sew the thread.

[0029] Here’s how it works:

[0030] First, a single layer of cloth is folded into two layers of cloth to form a cloth bag 14 structure, one side of the folded cloth is a cloth bag folding portion 141, and the other side is a cloth bag opening 142. Then, the compressed spring 12 is conveyed into the cloth bag 14 from the cloth bag opening 142, maintained in a compressed state by the upper pressing plate 10 and the lower pressing plate 11, and sewn by multiple sewing machines.

[0031] The first sewing mechanism 2 and the second sewing mechanism 3 move in the vertical direction to sew the vertical sewing line 7, and at the same time, cooperate with the spring strip pulling mechanism 1 to sew the horizontal sewing line 6. The movement directions of the first sewing mechanism 2 and the second sewing mechanism 3 can be the same or opposite, and are used to sew the cloth bag 14 and the cloth bag opening 142 between the springs 12, and the cloth bag folding part 141 can also be provided with a fourth sewing mechanism for sewing, that is, the fourth sewing mechanism is fixedly provided at the cloth bag folding part 141, so as to obtain the fourth sewing line 19 (such as Figure 5 As shown), the fourth sewing line 19 is the transverse sewing line 6.

[0032] The third sewing mechanism 4 is fixedly arranged at the cloth bag opening 142, and cooperates with the spring strip pulling mechanism 1 to sew the third sewing line 8 (transverse sewing line 6) at the cloth bag opening 142, and then through the trimming assembly 9 arranged on one side of the third sewing mechanism 4, the third sewing mechanism 4 can neatly cut off the excess cloth bag 14 edge material while sewing the third sewing line 8, so that the obtained spring strip 5 is more beautiful.

[0033] The above content is a further detailed description of the technical solution provided in combination with the preferred implementation methods of this patent. It cannot be determined that the specific implementation of the utility model is limited to the above descriptions. For ordinary technicians in the technical field to which this patent belongs, without departing from the concept of this patent, they can also make several simple deductions or substitutions, which should be deemed to fall within the scope of protection of this patent.
