The winding drum 20 is driven to rotate by the winding motor 22 to wind the base paper 10 wound around the winding drum 20.

[0035] Specifically, after the sponge raw material conveyed by the conveying device 3 peels off the sponge 23 and the base paper 10, and the sponge 23 and the base paper 10 are separated, the adhesive side of the sponge 23 faces upward. The sponge 23 continues to move towards the knife seat device 5. The base paper 10 bypasses the bottom of the paper peeling rod 18 to the rear side of the conveying device 3, and after bypassing the turning rod 19, it is wound around the winding drum 20. The unwound base paper 10 is wound by the rotation of the winding drum 20. Moreover, in order to adjust the base paper 10 to maintain a tensioned state during the winding process of the paper receiving device 4, a tensioning shaft is provided on the base 1. Tensioning wheels 24 are fixed on both sides of the tensioning shaft. The top of the tensioning wheels 24 contacts the lower surface of the base paper 10. An upward tension is provided to the base paper 10 through the tensioning wheels 24 to tension the base paper 10.

[0036] The knife seat device 5 includes a fixed knife seat 25 and a sliding knife seat 26. The fixed knife seat 25 is fixed on the base 1. The sliding knife seat 26 is slidably connected to the fixed knife seat 25. Specifically, the fixed knife seat 25 is fixed on the base 1 through a knife seat bracket 27. A chute is provided on the knife seat bracket 27. The sliding knife seat 26 is slidably arranged in the chute and can reciprocate back and forth along the chute. Blades 28 are fixed on the opposite side walls of the fixed knife seat 25 and the sliding knife seat 26. By the forward and backward sliding of the sliding knife seat 26, the sponge 23 with the wire harness pasted is cut by the blades 28 on the sliding knife seat 26 and the fixed knife seat 25.

[0037] A reciprocating drive device is fixed to the rear end of the sliding tool block 26. The reciprocating drive device includes a reciprocating motor 29, a driving bevel gear 30, a drive shaft 31, and a driving rack 32. The reciprocating motor 29 is fixed to the base 1. A driving bevel gear 30 is fixed to the output shaft of the reciprocating motor 29. The drive shaft 31 is rotatably arranged on the base 1. A driven bevel gear 33 and a transmission gear 34 are provided on the drive shaft 31. The driving bevel gear 30 on the reciprocating motor 29 is meshed and connected with the driven bevel gear 33 on the drive shaft 31. The transmission gear 34 on the drive shaft 31 is meshed and connected with the driving rack 32. By the forward or reverse rotation of the reciprocating motor 29, the driving rack 32 can be driven to move back and forth, so as to drive the sliding tool block 26 to approach or move away from the fixed tool block 25 through the driving rack 32, thereby enabling the blades 28 on the sliding tool block 26 and the fixed tool block 25 to complete the cutting action.

[0038] The control of the sliding tool block 26 of the present utility model is realized by the reciprocating motor 29. The reciprocating motor 29 adopts a stepping motor, specifically an 86BYGH250AL14J stepping motor. The power is transmitted by the rack connecting gear from the stepping motor to control the reciprocating movement of the sliding tool block 26. Specifically, the reciprocating motor 29 is controlled by an HJ-35K programmable stepping servo controller and is connected to the reciprocating motor 29 through a DM542 driver.

[0039] Compared with the existing sponge pasting equipment that adopts a gas-electric hybrid power mode, the traditional mode requires the setting of an air storage tank. The device of the present utility model is purely electric and does not require gas, making it convenient to use with less limitation. The wire harness sponge pasting device of the present utility model can be applicable to sponges of different widths and lengths. Sponges of different widths need to be equipped with corresponding blades 28. Currently, the sponge with the largest applicable width is 210 mm.

[0040] Specifically, when cutting the sponge 23 and the wire harness, the conveying device 3 moves a fixed distance in the direction of the tool block device 5 at a cycle. This distance is determined according to the width of the sponge for pasting the wire harness as required. When the conveying device 3 moves forward a certain distance of the sponge in one action, the operator horizontally places the wire harness and pastes it on the sponge, and holds both ends of the wire harness and presses it downward against the wire harness and the sponge. At the same time, the sliding tool block 26 moves forward, and the sliding tool block 26 and the fixed tool block 25 cooperate to cut the sponge with the wire harness pasted on this section, completing the operation of pasting the wire harness on the sponge.

[0041] When the present utility model works:

[0042] The sponge raw material is conveyed by the conveying device 3 in the width required for each conveyance. At the same time, the sponge and the base paper 10 are separated by the paper peeling rod 18 of the paper receiving device 4. The adhesive side of the sponge faces upward. After the sponge is conveyed out, the wire harness to which the sponge needs to be pasted is placed on the sponge, and then placed in the knife groove between the sliding action and the fixed tool holder 25. Press the switch to move the sliding tool holder 26 of the device 5 to cut the sponge. After the sliding tool holder 26 returns to its original position, take out the wire harness. At this time, the sponge has been completely pasted on the wire harness. The whole process takes about 2 seconds.

[0043] The wire harness sponge pasting device of the utility model can directly use the rolled sponge raw material. The sponge raw material can be directly used on the machine. The sponge is cut by the serrated blade 28. The raw material of the sponge roll 9 does not need secondary processing such as die cutting, saving one process and greatly saving the raw material cost and management cost.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
