Description

Technical Field

[0001] This invention relates to the field of stationery, and more particularly to a film applicator with a roller-shaped applicator head. Background Technology

[0002] Correction tape, also known as tape or correction tape, is a common stationery item used to cover up mistakes and provide carbon copy correction. There are many types of products available on the market.

[0003] The basic structure of a film applicator is that a feeding assembly and a recycling assembly are pivotally mounted inside the main body. The gears of the drive components mesh with the supply gear of the feeding assembly and the recycling gear of the recycling assembly, thereby linking the feeding assembly and the recycling assembly together.

[0004] The film strip is wound around the feed assembly and the recovery assembly, and bypasses the coating head that extends out of the body.

[0005] In use, the feeding assembly, driving gear, and recycling assembly rotate synchronously. The film strip extends from the feeding assembly, passes around the tongue plate, and the white adhesive tape on the surface of the film strip outside the film applicator sticks to the paper. The remaining base tape of the film strip extends towards the recycling assembly and is wound onto the recycling assembly.

[0006] like Figure 1 One of the existing technologies shown is that the applicator head 5 extending from the body 100 is an integrated plastic component with a U-shaped cross-section, and a tongue plate 51 between the baffles 52 on the left and right sides. The disadvantages of this technical solution are: the film tape wraps around the plate-shaped tongue plate 51, making the application process unsmooth; the film tape tends to move left and right during application, and the white tape tends to draw a serpentine pattern on the paper, resulting in poor application effect.

[0007] like Figure 2 , Figure 3 The second prior art shown features a coating head 6 extending from the main body 100, which is a plastic assembly consisting of a left support 61 and a right support 62. A fixed roller 63 and a roller shaft 65 pivotally mounted on a support shaft 64 are installed between the left and right support members 61 and 62. While this technical solution provides relatively smooth coating, it still suffers from problems such as the film tape 4 easily shifting left and right during coating, the white tape easily drawing serpentine patterns on the paper, and poor coating results.

[0008] The above are all potential problems and issues that may arise during the use of the current product, and further improvements are needed. Summary of the Invention

[0009] The present invention provides a film applicator with a roller-shaped applicator head, which aims to overcome the shortcomings of the prior art, make the application smooth, and prevent the white tape from drawing a snake-like pattern on the paper, thereby improving the application effect.

[0010] The technical solution adopted by this invention to solve its technical problem is:

[0011] A film applicator with a roller in the applicator head, wherein a feeding assembly and a recovery assembly are pivotally mounted on the body.

[0012] Its features are:

[0013] The applicator head extending from the main body consists of a front support, a rear support, and a roller.

[0014] The rear support component is mounted on the main body.

[0015] The rear support body has baffles on both sides. The two baffles protrude above the rear support body to form an upper channel, and the two baffles protrude below the rear support body to form a lower channel.

[0016] The main body of the front support component is fixedly connected to the main body of the rear support component.

[0017] The front support member has branches extending forward from both sides of its main body.

[0018] The cylindrical roller is rotatably mounted between the two front support branches;

[0019] The film strip is wound onto the feeding assembly, extends beyond the front end of the body, enters the upper channel, then passes around the roller, enters the lower channel, and finally extends into the body and is wound onto the recycling assembly.

[0020] The front support branch is provided with roller mounting holes;

[0021] Two coaxial cylindrical protrusions extend from the two sides of the cylindrical roller shaft;

[0022] The two protrusions of the roller shaft are respectively inserted into the two roller shaft mounting holes.

[0023] The lower part of the front end of the baffle has a stepped notch;

[0024] The front support branch includes a front part of the front support branch, a middle part of the front support branch, and a rear part of the front support branch connected in sequence, and the distance between the two front parts of the front support branch is greater than the distance between the two rear parts of the front support branch.

[0025] The roller mounting hole is located at the front of the branch of the front support component;

[0026] The front portions of the two front support branches are respectively located in the stepped notch.

[0027] The upper and lower surfaces of the rear support component body are respectively provided with rear support cylinders, and the front support component body has two clamping plates, one upper and one lower, with clamping plate through holes and clamping plate through holes, forming a clamping groove between the two clamping plates.

[0028] The rear support body is inserted into the clamping groove, and the upper and lower rear support cylinders of the rear support body are respectively inserted into the upper and lower clamping through holes, so that the front support body is fixedly connected to the rear support body.

[0029] The protrusions extending from both sides of the rear end of the rear support body are engaged in the mounting holes inside the body, thus allowing the rear support body to be mounted on the body.

[0030] The advantages of this invention are:

[0031] Compared to the existing integrated plastic applicator heads, the roller of this invention acts as a bearing, ensuring smooth application without jamming. Compared to the existing plastic composite applicator heads, the left and right baffles of this invention limit the movement of the film strip, preventing it from slipping to the left or right and solving the problem of creating a serpentine pattern.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0043] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown:

[0044] Inside the main body 100, a feeding assembly and a recycling assembly are pivotally mounted. The drive gear meshes with the supply gear of the feeding assembly and the recycling gear of the recycling assembly, respectively. The film strip 4 is wound on the feeding assembly and the recycling assembly and passes around the coating head that extends out of the main body 100.

[0045] The applicator head consists of a front support 1, a rear support 2, and a roller 3.

[0046] The rear support member 2 has a rear support member cylinder 20 protruding from its upper and lower surfaces, and the rear end of the rear support member body 21 is a mounting shaft 22. The protrusions 23 extending from both sides of the mounting shaft 22 are engaged in the mounting holes in the body 100.

[0047] The rear support body 21 has baffles 24 on both sides. The portion of the two baffles 24 exposed above the rear support body 21 forms an upper channel 26, and the portion of the two baffles 24 exposed below the rear support body 21 forms a lower channel 27.

[0048] A stepped notch 25 is provided at the lower part of the front end of the baffle 24.

[0049] The front support member 1 has two clamping pieces 12, one above the other. The clamping pieces 12 have through holes 10, and a groove 13 is formed between the two clamping pieces 12.

[0050] The front support body 11 has two front support branches 14 extending forward from its front ends. The front support branch 14 includes a front part 15, a middle part 16, and a rear part 17 connected in sequence. The distance between the two front parts 15 is greater than the distance between the two rear parts 17.

[0051] The front part 15 of the front support branch is provided with roller mounting holes 18.

[0052] The two sides of the cylindrical roller 3 have protruding cylindrical protrusions 31. The roller 3 and the protrusions 31 are coaxial.

[0053] The two protrusions 31 of the roller shaft 3 are respectively inserted into the roller shaft mounting holes 18 of the front part 15 of the two front support members, and the roller shaft 3 is rotatably mounted between the front parts 15 of the two front support members.

[0054] The rear support body 21 is inserted into the clamping groove 13, and the upper and lower rear support cylinders 20 of the rear support body 21 are respectively inserted into the upper and lower clamping through holes 10, thereby fixing the front support 1 on the rear support 2.

[0055] At this time, the front parts 15 of the two front support branches are respectively located in the step notches 25 at the lower front end of the two baffles 24.

[0056] Finally, the protrusions 23 extending from both sides of the mounting shaft 22 of the rear support member 2 are engaged in the mounting holes inside the body 100.

[0057] The film strip 4 is wound on the feeding assembly, extends out of the front end of the body 100 and enters the upper channel 26, then passes around the roller 3 and enters the lower channel 27, and finally extends into the body 100 and is wound on the recycling assembly.

[0058] In this way, the film strip 4 wraps around the roller 3, and when in use, the roller 3 rolls, making the coating process smooth and less prone to jamming.

[0059] After the film strip 4 extends out of the main body 100, it passes through the upper channel 26 and the lower channel 27. When in use, the baffles 24 on both sides of the upper channel 26 and the lower channel 27 can limit the film strip 4, making it less likely to run to the left or right, thus solving the problem of drawing a snake shape.

[0060] The front portions 15 of the two front support branches used for mounting the support roller 3 are located in the stepped notches 25 at the front ends of the two baffles 24, respectively, so as not to affect the film strip 4 wound on the roller 3. Furthermore, this ensures that all portions of the film strip 4 except those wound on the roller 3 are located in the upper channel 26 and lower channel 27, preventing it from running left or right in a serpentine pattern.

[0061] The various embodiments described in this specification are presented in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. The description of the disclosed embodiments enables those skilled in the art to make or use the invention.
