Description

Technical Field

[0001] This utility model relates to the field of paper limiting technology for printers, specifically to a paper limiting device for an anti-paper jam thermal transfer printer. Background Technology

[0002] Thermal transfer printing equipment is a type of printer specifically designed to print images or text onto special surfaces. Its principle is to use thermal transfer technology, which transfers the ink in the ribbon onto the target surface by controlling the temperature of the hot head. Currently, label printers are the most widely used type of printer on the market, and they generally use a carrier rack to store the adhesive film rolls.

[0003] Existing technologies can only limit the paper roll from the side, but the top is usually open, which can easily cause paper jams when the pulling force is large. Therefore, a paper limiting device for an anti-jamming thermal transfer printer is proposed to limit the self-adhesive paper roll and avoid paper jams when the pulling force is large. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a paper limiting device for an anti-jamming thermal transfer printer, which facilitates the limiting of self-adhesive paper rolls and avoids problems such as paper jams when the pulling force is large.

[0005] The technical solution adopted by this utility model to solve its technical problem is a paper limiting device for an anti-paper jam thermal transfer printer, including a printer body, a carrier frame, a lifting notch, a slide rail B and a support roller frame. A stretcher is installed on one bottom side of the carrier frame by bolts, and a concave limiting frame is provided on one outer side of the stretcher.

[0006] A lifting frame is provided on one side of the slide rail B, and the bottom of the lifting frame is located between the support roller frame and connected to the limit roller via a rotating shaft.

[0007] By adopting the above technical solution, the stretcher is fixed and the slide rail B is retracted using the support frame.

[0008] The self-adhesive paper roll is carried on a stretcher, and the concave limiting frame is pushed to limit it from the side with the cooperation of slide rail A. Then the positioning bolt is rotated to contact the bottom of the stretcher so that the concave limiting frame is positioned.

[0009] The slide rail B, in conjunction with the lifting frame, ensures smooth lifting and lowering, keeping the corresponding bottom limit roller in constant contact with the adhesive paper. The lifting frame passes through the lifting notch at the top of the concave limit frame.

[0010] The limiting roller is supported by the support roller frame at the bottom of the lifting frame. The limiting roller limits the top of the self-adhesive paper roll and rolls in conjunction with the paper output. The anti-slip pad around the limiting roller is made of rubber to increase the friction between it and the self-adhesive paper to achieve an anti-slip effect.

[0011] Specifically, the carrier is located inside one side of the printer body, and the top of the concave limiting frame has a lifting notch.

[0012] By adopting the above technical solution, the stretcher is fixed and the slide rail B is retracted using the support frame.

[0013] Specifically, both sides of the stretcher are provided with slide rails A through reserved grooves, and the concave limiting frame is slidably connected to the slide rails A through an inner wall slider.

[0014] By adopting the above technical solution, the slide rail B is used in conjunction with the lifting frame to achieve smooth lifting and lowering.

[0015] Specifically, a positioning bolt is inserted through a pre-reserved threaded hole on the bottom surface of the concave limiting frame corresponding to the position of the stretcher, and the top of the positioning bolt contacts the bottom of the stretcher.

[0016] By adopting the above technical solution, the rotating positioning bolt contacts the bottom of the stretcher, thereby positioning the concave limiting frame.

[0017] Specifically, the inner wall of the support frame is provided with a slide rail B through a reserved groove corresponding to the top of the stretcher, and the lifting frame is slidably connected to the slide rail B through a slider on one side.

[0018] By adopting the above technical solution, the slide rail B, in conjunction with the lifting frame, can be used to smoothly raise and lower the device so that the corresponding limit roller at the bottom is always in contact with the self-adhesive paper.

[0019] Specifically, the support roller frames are all bolted to both sides of the bottom of the lifting frame, and anti-slip pads made of rubber are attached to the outer periphery of the limiting rollers.

[0020] By adopting the above technical solution, the limiting roller is supported by the support roller frame at the bottom of the lifting frame.

[0021] The beneficial effects of this utility model are:

[0022] (1) The paper limiting device of the anti-paper jam thermal transfer printer described in this utility model uses the slide rail B in conjunction with the lifting frame to smoothly lift and lower the paper so that the corresponding limiting roller at the bottom is always in contact with the self-adhesive paper, and the lifting frame passes through the lifting notch at the top of the concave limiting frame.

[0023] (2) The paper limiting device of the anti-paper jam thermal transfer printer described in this utility model is provided by the support roller frame supporting the limiting roller at the bottom of the lifting frame. The limiting roller limits the top of the self-adhesive paper roll and rolls in coordination when the paper is output. The anti-slip pad around the limiting roller is made of rubber material to increase the friction between it and the self-adhesive paper to achieve the anti-slip effect. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] To avoid problems such as paper jams when subjected to strong pulling force, such as Figure 1-3 As shown, the paper limiting device of the anti-paper jam thermal transfer printer of this utility model includes a printer body 1, a carrier frame 2, a lifting notch 7, a slide rail B8 and a support roller frame 11. A stretcher 3 is installed on one bottom side of the carrier frame 2 by bolts, and a concave limiting frame 5 is provided on one side of the periphery of the stretcher 3.

[0031] A lifting frame 9 is provided on one side of the slide rail B8, and the bottom of the lifting frame 9 is located between the support roller frame 11 and connected to the limiting roller 10 through a rotating shaft.

[0032] When in use, the stretcher 3 and the retraction slide rail B8 are supported and fixed by the support frame 2;

[0033] The stretcher 3 carries the roll of self-adhesive paper, and with the cooperation of the slide rail A4, the concave limiting frame 5 is pushed to limit it from the side. Then, the positioning bolt 6 is rotated to contact the bottom of the stretcher 3 so that the concave limiting frame 5 is positioned.

[0034] The slide rail B8, in conjunction with the lifting frame 9, smoothly raises and lowers the paper so that the corresponding bottom limiting roller 10 is always in contact with the self-adhesive paper, and the lifting notch 7 at the top of the concave limiting frame 5 allows the lifting frame 9 to pass through and lift.

[0035] The support roller frame 11 supports the limiting roller 10 at the bottom of the lifting frame 9. The limiting roller 10 limits the top of the self-adhesive paper roll and rolls it in conjunction with the paper output. The anti-slip pad 12 on the periphery of the limiting roller 10 is made of rubber to increase the friction between it and the self-adhesive paper to achieve an anti-slip effect.

[0036] To avoid problems such as paper jams when the pulling force is large, for example, such as Figure 1 , Figure 2 As shown, the present invention also includes the carrier 2 disposed inside one side of the printer body 1, and the top of the concave limiting frame 5 having a lifting notch 7.

[0037] When in use, the carrier 2 is fixed by the printer body 1 (Panyue Materials Technology (Suzhou) Co., Ltd.; Item No.: FT3406).

[0038] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes that both sides of the stretcher 3 are provided with slide rails A4 through reserved grooves, and the concave limiting frame 5 is slidably connected to the slide rails A4 through an inner wall slider.

[0039] During use, the slide rail B8 works in conjunction with the lifting frame 9 to raise and lower the object smoothly.

[0040] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes a positioning bolt 6 passing through a pre-reserved threaded hole on the bottom surface of the concave limiting frame 5 corresponding to the position of the stretcher 3, and the top end of the positioning bolt 6 is in contact with the bottom of the stretcher 3.

[0041] When in use, the rotating positioning bolt 6 contacts the bottom of the stretcher 3, thereby positioning the concave limiting frame 5.

[0042] For example, such as Figure 1 As shown, the present invention also includes a slide rail B8 provided on the inner wall of the support frame 2 corresponding to the top of the stretcher 3 through a reserved groove, and the lifting frame 9 is slidably connected to the slide rail B8 through a slider on one side.

[0043] During use, the slide rail B8, in conjunction with the lifting frame 9, smoothly raises and lowers the device so that the corresponding bottom limit roller 10 is always in contact with the self-adhesive paper.

[0044] For example, such as Figure 1 , Figure 3As shown, the present invention also includes that the support roller frame 11 is bolted to both sides of the bottom of the lifting frame 9, and the periphery of the limiting roller 10 is provided with an anti-slip pad 12, which is made of rubber material.

[0045] When in use, the limiting roller 10 is supported by the support roller frame 11 and is located at the bottom of the lifting frame 9.

[0046] In use, this utility model uses the support frame 2 to support and fix the stretcher 3 and the retraction slide rail B8.

[0047] The stretcher 3 carries the roll of self-adhesive paper, and with the cooperation of the slide rail A4, the concave limiting frame 5 is pushed to limit it from the side. Then, the positioning bolt 6 is rotated to contact the bottom of the stretcher 3 so that the concave limiting frame 5 is positioned.

[0048] The slide rail B8, in conjunction with the lifting frame 9, smoothly raises and lowers the paper so that the corresponding bottom limiting roller 10 is always in contact with the self-adhesive paper, and the lifting notch 7 at the top of the concave limiting frame 5 allows the lifting frame 9 to pass through and lift.

[0049] The support roller frame 11 supports the limiting roller 10 at the bottom of the lifting frame 9. The limiting roller 10 limits the top of the self-adhesive paper roll and rolls it in conjunction with the paper output. The anti-slip pad 12 on the periphery of the limiting roller 10 is made of rubber to increase the friction between it and the self-adhesive paper to achieve an anti-slip effect.
