DETAILED DESCRIPTION

[0029] The utility model will be further explained in combination with specific implementation.

[0030] In the following description, the concepts of up, down, left, right, front and back (or called directional) are all in the position state of the figure being described, and the purpose is to facilitate the public to understand, so it cannot be understood as a special limitation on the technical solutions provided by the utility model.

[0031] As shown in Figures 1-12 , a spring strip conveying device includes a winding wheel assembly 1, a tensioning wheel assembly, a conveying assembly 3 and a workbench 4, the winding wheel assembly cooperates with the conveying assembly 3 to convey the spring strip 5 from the upstream of the winding wheel assembly to the workbench 4; the tensioning wheel assembly is arranged on one side of the workbench 4 and is used to avoid mutual entanglement of the spring strips 5 during the conveying process.

[0032] One side of the conveying assembly 3 is provided with a guide wheel row 6, the guide wheel row 6 includes horizontal row rollers 64, oppositely arranged first wheel row pieces 61 and second wheel row pieces 62, and a plurality of vertical row rollers 63 are arranged on the first wheel row pieces 61 and the second wheel row pieces 62. Among them, the first wheel row pieces 61 and the second wheel row pieces 62 can be close to or away from each other to adapt to different specifications of the spring strips 5.

[0033] The tensioning wheel assembly includes at least one tensioning wheel 2, and a single tensioning wheel 2 can be fixed on the same fixed plate as the guide wheel row 6 (as shown in Figure 7 ), or can be separately arranged and can be adjusted forward and backward (as shown in Figure 8 ). The tensioning wheel assembly can also include two tensioning wheels 2, and the two tensioning wheels 2 are arranged left and right (as shown in Figure 9 ) or front and back (as shown in Figure 10 ).

[0034] The conveying assembly 3 includes a push wheel 311, a vertical guide wheel 312 and a horizontal guide wheel 313 (as shown in Figure 11). Alternatively, the conveying assembly 3 comprises two sets of feeding members 31 arranged oppositely, each set of feeding members 31 comprising a pushing wheel 311 and a guide wheel, the guide wheel comprising a vertical guide wheel 312 and a horizontal guide wheel 313. The two sets of feeding members 41 can be moved closer to or away from each other to adapt to different specifications of the spring strip 5 (for example Figure 12 ). Embodiment 1

[0035] According to the specification of the spring strip 5, the distance between the vertical row of rollers 63 on the first row member 61 and the vertical row of rollers 63 on the second row member 62 of the guide wheel row 6, and the distance between the two sets of feeding members 311 are adjusted.

[0036] The spring strip 5 is then conveyed from the upstream of the winding wheel assembly 1 (usually a spring machine) to the workbench 4 by the cooperation of the winding wheel assembly 1 and the conveying assembly 3. When the spring strip 5 is conveyed from the winding wheel assembly 1 to the conveying assembly 3, the spring strip 5 is prone to folding and mixing together, which will affect the transmission of the conveying assembly 3. Therefore, the guide wheel row 6 and a fixedly arranged tensioning wheel 2 (the tensioning wheel 2 can be a non-powered roller or a powered roller) are arranged, and the tensioning wheel 2 and the guide wheel row 6 are arranged on the same work plane (the same fixed plate) (as shown in Figure 7 ).

[0037] Specifically, the spring strip 5 is first conveyed to the guide wheel row 6 by the winding wheel assembly 1, and then conveyed to the tensioning wheel 2 by the guide wheel row 6. After the position of the spring strip 5 is adjusted by the tensioning wheel 2, the spring strip 5 is conveyed between the two sets of feeding members 31 of the conveying assembly 3. The conveying assembly 3 can reciprocate horizontally (left and right movement) on the workbench 4 to convey the spring strip 5 to the workbench 4, and then the upper and lower sealing knife assemblies 7 arranged on the upper and lower sides of the workbench 4 are used to move up and down to weld with the ultrasonic die 8. The two rows of spring strips 5 connected on the workbench 4 are welded, and it should be noted that the welding mode of the two sets of sealing knife assemblies 7 and the ultrasonic die 8 is alternating welding, that is, the two sets of sealing knife assemblies 7 are arranged alternately and welded with the ultrasonic die 8.

[0038] After each welding is completed, the welded spring strip 5 is moved a distance to the rear end of the workbench 4 by the push rod 9 (the push rod 9 can move forward and backward, left and right, and up and down, so it will not interfere with the ultrasonic welding process), so that the conveying assembly 3 can stably convey the spring strip 5 to the workbench 4. Embodiment 2

[0039] The other structures are the same as those of embodiment 1, wherein the tensioning wheel 2 used is movable and adjustable in relative position, and the tensioning wheel 2 and the guide wheel row 6 are arranged on two work planes (two fixed plates respectively) (as shown in Figure 8As shown in FIG. 1, the tensioning wheel 2 moves in the left-right direction of the fixed plate to adjust the relative position of the spring strip 5. Embodiment 3

[0040] The other structures are the same as those in Embodiment 1, wherein two tensioning wheels 2 are adopted, and the two tensioning wheels 2 can be arranged together with the guide wheel row 6 on one fixed plate or arranged separately with the guide wheel row 6 on different fixed plates. Figure 11 And Figure 12 The two tensioning wheel assemblies disclosed in the above two embodiments are arranged together with the guide wheel row 6 on one fixed plate. Figure 11 The two tensioning wheels 2 in Embodiment 1 are arranged left and right, Figure 12 The two tensioning wheels 2 in Embodiment 2 are arranged front and back, and the spring strip 5 is conveyed between the two tensioning wheels 2 and then conveyed to the conveying assembly 3 after the relative position is adjusted. In addition, the distance between the two tensioning wheels 2 can also be adjusted according to the specifications of the spring strip 5.

[0041] The above is a further detailed description of the technical solutions provided in combination with the preferred embodiments of the present patent, and the specific implementation of the present patent should not be limited to the above description. For ordinary skilled persons in the technical field to which the present patent belongs, a number of simple deductions or replacements can be made without departing from the concept of the present patent, and all of them should be regarded as falling within the protection scope of the present patent.
