[0031] The following combines Figures 1-6 to describe the present utility model in detail

[0032] An automatic tape rewinding device includes a frame 10. One end of the frame 10 is provided with an unwinding shaft 101, and a tape roll 1011 is movably sleeved on the unwinding shaft 101. The other end of the frame 10 is provided with a first motor 201 and a winding roller 102 connected to the output end of the first motor 201. A winding shell for bonding one end of the tape of the tape roll 1011 is sleeved on the winding roller 102

[0033] The frame 10 is provided with a second motor 202. The output end of the second motor 202 is connected with a cutting member 1031. An elastic member 1032 is arranged on one side of the cutting member 1031. The elastic member 1032 is connected with a pressing member 1033. The cutting member 1031 and the pressing member 1033 are located on the tape winding path, and in the natural state, the bottom of the pressing member 1033 is closer to the tape on the winding path than the bottom of the cutting member 1031

[0034] The frame 10 is provided with a guide shaft 30 that can abut against the tape; one end of the unwinding shaft 101 is provided with a detachable limiting portion for restricting the movement of the tape roll 1011 in the axial direction of the unwinding shaft 101.

[0035] Specifically, the cutting member 1031 is driven by the second motor 202 to slide downward. During the downward sliding process of the cutting member 1031, the pressing member 1033 will be driven to slide downward, and before the cutting member 1031 contacts the tape, the pressing member 1033 has already abutted against the tape, playing a role in fixing the tape; when the cutting member 1031 continues to slide downward, the pressing member 1033 moves upward under the action of the elastic member 1032, and the cutting member 1031 can cut the tape. After cutting, the cutting member 1031 and the pressing member 1033 slide upward to return to the original position under the action of the second motor 202, and the elastic member 1032 also returns to its original state. The cutting member 1031 can be set closer to the winding roller 102, or the pressing member 1033 can be set closer to the winding roller 102. The positions of the two can be swapped as long as it is ensured that the pressing member 1033 contacts the tape first during the downward movement; the distance between the cutting member 1031 and the pressing member 1033 can also be appropriately increased, and the pressing member 1033 can be arranged at a position directly above the winding roller 102. In this way, not only can it play a pressing role during cutting, but also a flattening role during the tail-end winding after cutting, making the winding effect better.

[0036] In this embodiment, the bottom of the cutting member 1031 is provided with sawteeth or a sharp edge, and the bottom of the pressing member 1033 is provided with a protective sleeve; further, the protective sleeve is made of silicone material, and other materials that prevent scratching and damage in the prior art can also be used.

[0037] In this embodiment, the frame 10 is provided with a display 40, and the display 40 is electrically connected to the first motor 201 and the second motor 202. The setting of the display 40 facilitates real-time viewing of the rotation speed of the current winding roller 102 and the downward speed of the cutting member 1031, and is convenient for timely adjustment.

[0038] In this embodiment, a dust-proof plate 50 is provided at the top of the frame 10, and the dust-proof plate 50 is used to prevent dust from falling into the tape winding path.

[0039] In this embodiment, a dust removal device is provided between the material feeding shaft 101 and the material collecting roller 102. The dust removal device at least includes a first dust removal device, and the first dust removal device includes a third motor 203 and an electrostatic dust removal roller 105 connected to the output end of the third motor 203. The electrostatic dust removal roller 105 adsorbs the dust and micro foreign matters on the surface of the tape, which can effectively avoid the problem that the lint and dust remaining on the tape surface cause the adhesive to be not firm during pasting, improve the cleanliness of the tape rewinding, and thus improve the effect of the tape rewinding. Specifically, the electrostatic dust removal roller 105 is arranged above the position between the material feeding shaft 101 and the material collecting roller 102, and there are two electrostatic dust removal rollers 105, and the tape passes through the gap between the two electrostatic dust removal rollers 105. Correspondingly, there are also two third motors 203, which are electrically connected to the second control unit 2021. The electrostatic dust removal roller 105 belongs to the prior art and will not be described in detail here.

[0040] In this embodiment, the dust removal device further includes a second dust removal device, and the second dust removal device is located between the material feeding shaft 101 and the first dust removal device.

[0041] In this embodiment, the second dust removal device includes a fourth motor 204 and a dust removal drum 1061 connected to the output end of the fourth motor 204. The second dust removal device further includes a dust suction box 1062 located below the dust removal drum 1061. The dust suction box 1062 is provided with an opening facing the dust removal drum 1061. A dust suction part 1063 is provided at the bottom of the dust suction box 1062, and an adsorption net 1064 is further provided in the dust suction box 1062 above the dust suction part 1063.

[0042] Specifically, the dust removal drum 1061 abuts against the tape. The fourth motor 204 is electrically connected to the fourth control unit 2041. The fourth motor 204 drives the dust removal drum 1061 to roll. During the rolling process, the dust removal drum 1061 wipes away the dust on the tape. At the same time, the fifth control unit (not shown in the figure) controls the operation of the dust suction part 1063. The dust suction part 1063 generates suction, so as to suck the dust generated by the dust removal drum 1061 wiping the tape surface. The dust will enter the dust suction box 1062 and be adsorbed by the adsorption net 1064 to complete the treatment of the dust on the tape surface. Specifically, the dust suction part 1063 is an air extraction fan blade. The second dust removal device belongs to the prior art, and its principle and process refer to the prior art.

[0043] The simultaneous setting of the first dust removal device and the second dust removal device plays a role of double dust removal and better dust removal effect. The first dust removal device and the second dust removal device can be interchanged, can be changed to other common dust removal devices in the prior art, or can be changed to two identical devices.

[0044] In this embodiment, the adsorption net 1064 is slidably connected to the inner wall of the dust suction box 1062, and a notch 1065 for pulling out the adsorption net 1064 is provided on the outer side wall of the dust suction box 1062. Specifically, the adsorption net 1064 is provided with a pull ring located outside the dust suction box 1062, which is convenient for pulling out the adsorption net 1064 from the front of the dust suction box 1062.

[0045] In this embodiment, a receiving cavity 1066 that is located above the adsorption net 1064 and adapted to the shape of the dust removal roller 1061 is provided in the dust suction box 1062. The setting of the receiving cavity 1066 facilitates the dust removal roller 1061 to be closer to the adsorption net 1064 and the dust suction part 1063, achieving a better effect of sucking dust.

[0046] In this embodiment, the feeding shaft 101 includes a first cylinder and a second cylinder whose radial dimension is smaller than that of the first cylinder. The limiting part includes a limiting plate 104. The limiting plate 104 is sleeved on the second cylinder, and one side of the limiting plate 104 abuts against the first cylinder. The limiting part further includes a locking member threadedly connected to the second cylinder, and the other side of the limiting plate 104 abuts against the locking member (not shown in the figure). Specifically, the part of the feeding shaft 101 close to the frame 10 is the first cylinder, the part of the feeding shaft 101 far from the frame 10 is the second cylinder, and the first cylinder and the second cylinder are coaxially arranged.

[0047] In this embodiment, the take-up roller 102 rotates counterclockwise driven by the first motor 201. Therefore, when pulling one end of the tape, the tape roll 1011 on the feeding shaft 101 is also rotated counterclockwise. After one end of the tape roll 1011 is pulled, it will sequentially pass through the guide shaft 30, the second dust removal device, the first dust removal device, and finally be wound into the take-up shell on the take-up roller 102; the guide shaft 30 guides the movement of the tape; the first motor 201 is electrically connected to the first control part 2011 provided on the frame 10, the second motor 202 is electrically connected to the second control part 2021 provided on the frame 10, the third motor 203 is electrically connected to the third control part 2031 provided on the frame 10, and the fourth motor 204 is electrically connected to the fourth control part 2041 provided on the frame 10.

[0048] In order to prevent the tape from adhering to the dust removal device or the guide shaft 30 during the winding process, some measures will be taken during the production process, such as using isolation materials, coatings, or applying anti-sticking agents on the guide shaft 30, etc. Specific reference can be made to the existing technologies in this field.

[0049] The working principle of an automatic tape winding device proposed by the present utility model is as follows:

[0050] In use, the tape roll 1011 is movably sleeved on the unwinding shaft 101. A winding shell is sleeved on the winding roller 102 and the winding shell is detachably and fixedly connected to the winding roller 102. The limiting plate 104 is sleeved on the second cylinder, one side of the limiting plate 104 abuts against the first cylinder, and then a nut is arranged at the position on the other side of the limiting plate 104 as a locking member, and the nut is threadedly connected to the second cylinder. Start pulling one end of the tape on the tape roll 1011, and make it pass through the guide shaft 30, the second dust removal device, the first dust removal device in sequence and then adhere to the winding shell. Start the first motor 201 through the first control unit 2011 to drive the winding roller 102 to rotate. The winding roller 102 is fixed to the winding shell, so the winding shell rotates together with the winding roller 102. During the winding process, the second dust removal device and the first dust removal device perform dust removal and cleaning on the surface of the tape. After the winding is completed, drive the cutting member 1031 to slide down for cutting through the second motor 202. After the cutting is completed, remove the winding shell from the winding roller 102.

[0051] The above embodiments are only used to illustrate the technical concept and features of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it, and cannot be used to limit the protection scope of the present invention.
