Description

Technical Field

[0001] This utility model relates to the technical field of tape sealing devices, specifically a hand-held box sealer. Background Technology

[0002] Carton sealers are a convenient tool we frequently use in our daily work and life when packing and sealing boxes. They can reinforce and seal the surface of already placed boxes with tape, greatly improving our work efficiency. However, in practice, problems such as misplacement or omissions often occur, requiring the unpacking of already packed boxes. Furthermore, due to tape quality and improper handling by workers, tape may stick or break during the packaging process. To solve this problem, carton sealers with utility knife sheaths (CN218909340U) have appeared on the market. However, because the utility knife is long, it can easily cause accidental injury during operation and tends to stick to the tape, increasing time costs. In addition, after completing the packing and sealing work, we need to mark the boxes and record the information in the work log, requiring markers and ballpoint pens. However, the latest carton sealer products on the market only have pen holder grooves for both types of pens (CN220430686U), which is inconvenient for pen storage and replacement. In addition, traditional hand-held carton sealers lack a handle and are made of a single injection-molded structure. When the operation time is long, sweat will accumulate on the hand grip, affecting the sealing efficiency. Summary of the Invention

[0003] To solve the following problem:

[0004] 1. Solve the problem of reopening sealed boxes, while avoiding accidental injury to the human body caused by the cutting blade of the box sealer and the problem of adhesion to the tape;

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Example: Figure 1-6 As shown, this utility model provides a handheld box sealer, including a knife barrel 1, an anti-slip rubber sheet 2, a pen holder 3, and a box sealer body 4.

[0042] In this embodiment, by pressing the push button body 12, the spring body 15 on the spring pin 14 is deformed, which applies pressure to the slide bar table 17, so that the slide bar table 17 is in close contact with the slide bar groove 21 on the inner wall of the blade barrel 1, thereby driving the box-opening blade 18 to be in close contact with the blade groove 22.

[0043] Furthermore, while pressing the push button body 12, a pushing force is applied, allowing it to slide left and right within the push button groove 23. When it slides to the top left or right, the first limiting piece 13 will engage with the notch 20 on the inner wall, fixing the position of the slide bar 17, and thus fixing the position of the box-opening blade 18, realizing the functions of extending and retracting the blade, avoiding the shaking of the box-opening blade 18 during use, and improving the stability of repeated box-opening operations.

[0044] In this embodiment, the box-opening blade 18 is a stainless steel blade with a surface coating of polytetrafluoroethylene (Teflon), which reduces the probability of it sticking to the tape 43. The width of the box-opening blade 18 does not exceed 1 cm, and the longest distance extending beyond the blade edge 19 does not exceed 2 cm, to avoid accidental hand injury due to an excessively long or wide blade and to improve the safety of the box-opening operation.

[0045] In this embodiment, the grip area is covered with a layer of non-slip raised rubber sheet 2, which increases the friction between the hand and the handle, and solves the problem of poor grip caused by sweaty palms during long operation time, thus improving the interactive operation.

[0046] In this embodiment, the connecting strip 31 and the fixing disc 33 are an integral structure. The fixing disc 33 is fitted onto the fixing post 35 on the torsion cylinder cover 34, and the first bolt 32 is rotated and fixed on the fixing post 35 to prevent the fixing disc 33 from falling off.

[0047] Furthermore, the other end of the connecting strip 31 extends into the inner wall of the pen holder 3 until the second limiting piece 37 at the end is fixed to the nut 36 and fits tightly with the groove on the outer wall of the pen holder 3, thereby fixing the connecting strip 31 and ensuring that the twist cap 34 will not be lost.

[0048] In this embodiment, the pen holder 3 is opened and closed by rotating and twisting the cap 34. Several markers, ballpoint pens and pen refills can be stored in the pen holder 3, which enables timely marking and recording after the sealing and unsealing process, and facilitates replacement without loss.

[0049] In this embodiment, the base plate 48 is fixed to the sealing device platform 41 by the second bolt 482, and the side cover plate 45 is fixed to the two internally threaded third positioning posts 481 on the base plate 48 by the screw 44. At the same time, the two pressure rollers 47 are fitted on the corresponding third positioning posts 481 to apply pressure to the tape 43, reducing the situation of poor adhesion caused by the shaking of the tape 43. The surface of the outer pressure roller 471 near the cutting blade 49 is serrated to increase the contact friction with the tape 43 and reduce slippage.

[0050] In this embodiment, the knife barrel 1 and the pen barrel 3 are not connected to each other and are integral with the sealing device platform 41.

[0051] In this embodiment, the actuating rod 421 in the clamping mechanism 42 is embedded in the first positioning post 411 on the sealing device platform 41, and the two ends of the roller 422 are respectively embedded in the second positioning post 412 and the positioning groove 413 on the sealing device platform 41. Two clamping springs 423 are fitted onto the roller 422, with one end contacting the flat contact surface on the actuating rod 421 and the other end contacting the inner wall of the sealing device platform 41.

[0052] In this embodiment, when the lever 421 is moved, the tape 43 is put into the lever. The compression spring 423 will apply pressure to the lever 421, causing it to apply pressure to the tape 43 inward to the pressure roller 472, thereby fixing the position of the tape 43.

[0053] Furthermore, pull the tape head on the tape 43 so that it passes through the guide roller 46 and the outer pressure roller 471 and comes into close contact with the cutting blade 49, while adhering to the box body that needs to be sealed. At this point, the box can be sealed. By holding the anti-slip embossed rubber sheet 2, downward pressure is applied to the sealing machine platform 41. At this point, simply tilt the cutting blade 49 slightly backward, and the tape 43 will be cut, completing the sealing operation.

[0054] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0055] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
