Technical Field

[0001] The utility model relates to the technical field of tape processing, in particular to a tape rewinder for preventing deviation. Background Technique

[0002] A tape is composed of a base material and an adhesive. Two or more unconnected objects are connected together through adhesion, and an adhesive is coated on its surface.

[0003] A rewinder is used in tape production. The rewinder plays the role of rewinding and slitting, and can be used to slit wide tapes. When the existing rewinder passes the tape, the tape is prone to deviation when moving along the round roller, which affects the rewinding of the tape.

[0004] In view of this, we propose a tape rewinder for preventing deviation. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a tape rewinder for preventing deviation, so as to solve the technical problem that the tape is prone to deviation when moving along the round roller, which affects the rewinding of the tape.

[0006] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a tape rewinder for preventing deviation, including a rewinder body and also including anti-deviation wheels;

[0007] Two anti-deviation wheels are symmetrically arranged on both sides of the frame of the rewinder body;

[0008] Wherein, a connecting shaft is arranged on the outer side of the anti-deviation wheel, the connecting shaft penetrates through the frame of the rewinder body, and the connecting shaft is rotationally connected with the frame of the rewinder body through a bearing;

[0009] Wherein, the anti-deviation wheel is in a frustum shape, and the narrow ends of the two anti-deviation wheels face each other.

[0010] Preferably, a positioning structure is arranged on the top side of the frame of the rewinder body corresponding to the anti-deviation wheel;

[0011] The positioning structure includes a screw rod, a turning handle, a cross plate and a positioning block;

[0012] The inner end of the screw rod is rotationally connected with the top side of the frame of the rewinder body through a rotating shaft;

[0013] The turning handle is fixedly arranged at the outer end of the screw rod;

[0014] One end of the cross plate is threadedly sleeved on the screw rod;

[0015] The positioning block is fixedly arranged at the bottom side of the other end of the cross plate;

[0020] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0021] 1. By setting the anti-deviation wheel, the edge of the tape passes along the conical anti-deviation wheel. When the tape deviates, the edge of the tape will deviate at the conical surface of the anti-deviation wheel, and the resistance received is large, which hinders the deviation of the tape.

[0030] The present utility model will be further described below with reference to the drawings and embodiments:

[0031] Embodiment 1: An anti-offset tape rewinder, see Figures 1 to 4, including a rewinder body 1, and further including deviation prevention wheels 2;

[0032] The two deviation prevention wheels 2 are symmetrically arranged on both sides of the frame of the rewinder body 1; wherein, a connecting shaft 4 is provided on the outer side of the deviation prevention wheel 2, the connecting shaft 4 penetrates through the frame of the rewinder body 1, and the connecting shaft 4 is rotatably connected to the frame of the rewinder body 1 through a bearing; wherein, the deviation prevention wheel 2 is in a frustum shape, and the narrow ends of the two deviation prevention wheels 2 face each other.

[0033] By arranging the deviation prevention wheel 2 in the present utility model, the edge of the tape passes along the frustum-shaped deviation prevention wheel 2. When the tape deviates, the edge of the tape will deviate at the frustum surface of the deviation prevention wheel 2, and the resistance received is large, which hinders the deviation of the tape. This solves the problem that the tape is prone to deviation when moving along the round roller, affecting the rewinding of the tape.

[0034] Specifically, a positioning structure 3 is arranged on the top side of the frame of the rewinder body 1 corresponding to the deviation prevention wheel 2;

[0035] The positioning structure 3 includes a screw rod 301, a turning handle 304, a cross plate 302 and a positioning block 303;

[0036] The inner end of the screw rod 301 is rotatably connected to the top side of the frame of the rewinder body 1 through a rotating shaft; the turning handle 304 is fixedly arranged at the outer end of the screw rod 301; one end of the cross plate 302 is threadedly sleeved on the screw rod 301; the positioning block 303 is fixedly arranged at the bottom side of the other end of the cross plate 302; wherein, the bottom side of the positioning block 303 is set to be an arc surface, and the bottom side of the positioning block 303 is adapted to the inclined surface of the deviation prevention wheel 2.

[0037] By arranging the screw rod 301, the turning handle 304, the cross plate 302 and the positioning block 303 in the present utility model, when placing the passing tape, the positioning block 303 can be moved down to press the tape, and the collecting roller is rotated to make the tape taut, and the tape is not easily separated from the deviation prevention wheel 2.

[0038] Further, arc surfaces 3031 are arranged at both protruding ends of the bottom side of the positioning block 303, which will not scratch the tape.

[0039] Still further, a guide rod 305 is penetrated through one end of the cross plate 302, and the bottom end of the guide rod 305 is fixedly connected to the top side of the frame of the rewinder body 1.

[0040] By arranging the guide rod 305 in the present utility model, it has the advantages of guiding the moving cross plate 302 and making the cross plate 302 move stably.

[0041] It should be noted that the top end of the guide rod 305 is lower than the turning handle 304, which does not affect the rotation of the turning handle 304.

[0042] Working principle: When using the device of the present utility model, pull out the tape through the rollers on the rewinder body 1. The edge of the tape passes through and is pulled out for a certain distance along the conical deviation-preventing wheel 2. Rotate the turning handle 304, and the screw 301 rotates to drive the cross plate 302 to move downward along the guide rod 305 until the bottom side of the positioning block 303 presses the tape at the deviation-preventing wheel 2. Then wind the pulled-out tape around the collecting roller and rotate the collecting roller to tighten the tape. Rotate the turning handle 304 in the reverse direction, and the screw 301 rotates in the reverse direction to drive the cross plate 302 to move upward along the guide rod 305 until the bottom side of the positioning block 303 no longer presses the tape, and the tape is rewound under the rotation of the shaft of the rewinder body 1. The edge of the tape will move at the conical surface of the deviation-preventing wheel 2. When the tape deviates, the conical surface setting makes the resistance received by the tape large, hindering the tape from deviating.

[0043] The embodiments disclosed in the present utility model are preferred embodiments, but not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present utility model based on the above embodiments and make different extensions and changes. As long as they do not depart from the spirit of the present utility model, they are within the protection scope of the present utility model.
