Technical Field

The invention relates to a handheld rapid heating film cutting bonder, in particular to a device which can instantly complete cutting and bonding by melting a film through heating.

Background

Fig. 1 shows a schematic diagram of a conventional electric heating pen 9.

The appearance of the pen generally includes a pen shaft 910 and a pen head 920. The tip 920 may be heated for bronzing or sealing.

However, the tip 920 of the conventional electric heating pen 9 has a square shape, so that the heating area is very large, a large crack may be formed, and a fine sealing line cannot be formed, so that a plastic bag cannot be sealed quickly; or, when sealing, the solid, liquid or gas contained in the plastic bag can escape due to larger cracks; or, the user must adjust the relative position between the plastic bag and the electric heating pen 9 to smoothly complete the sealing.

On the other hand, the conventional electric heating pen 9 has a switch 930 provided on the casing of the pen shaft 910, and it is inconvenient for a user to manually turn on the switch 930 before starting use and to manually turn off the switch 930 even after finishing use. In addition, the existing electric heating pen 9 is powered by an electric wire 940.

Therefore, it is desirable to provide a device that can instantly complete the cutting and bonding by melting the film by heating, so as to eliminate or alleviate the above-mentioned problems.

Fig. 2 shows an exploded view of the hand-held rapid thermal film cutting bonder 1 in accordance with one embodiment of the present invention.

The handheld rapid heating film cutting bonder 1 of the present invention mainly comprises a housing 100, a power supply module 200 and an electric heating base set 300.

The housing 100 is formed with an opening 110. Specifically, the housing 100 may include a lower shell 101, an upper shell 102, a front shell 103 and/or a front cover 104. Further, any combination of the lower case 101, the upper case 102, the front case 103, or the front cover 104 may be integrally formed; of course, they can be fastened together by screws, or embedded by inserts, or adhered by adhesives. In the embodiment of fig. 2, the lower case 101 is integrally formed with the front case 103. In addition, the upper case 102 serves as a battery cover, but is not limited thereto. The housing 100 may be made of plastic to reduce weight, but other materials, such as metal, may be used for rigidity or texture. The housing 100 may be manufactured by a 3D printing technique, in addition to a molding technique.

In addition, in some embodiments not shown in the drawings, the housing 100 may include a telescopic structure, and when the user dials the button, the heating wires 310 of the electric base set 300 may extend out of or retract into the opening 110 of the housing 100.

The power supply module 200 is disposed in the inner space of the housing 100. The power supply module 200 may be a disposable battery pack or a rechargeable battery pack. The battery can be mainly AA or AAA sized. Of course, an external power source may be used instead of the battery pack, and the power supply module 200 may be a linear power supply circuit, a switching power supply circuit, or a programmable power supply circuit and connected to the external power source in a wired or wireless manner. These circuits can be used for ac-dc conversion to provide the required current or voltage.

The electric heating socket set 300 receives power from the power supply module 200 and includes a heating wire 310. The heating wire 310 extends at least partially out of the opening 110 of the housing 100 to heat and melt a region of at least one film. The at least one film is, for example, a plastic film, a front and rear two-layer film or a multi-layer film when the plastic bag is folded. The thin film is a film that can be melted and cut by the heating wire 310 of the present invention.

With respect to the heating wire 310, the power is set to provide a heating temperature at which the area of the melted film is cooled to be bonded within 1 second ± 0.5 second, so as to rapidly complete the sealing, preventing the solid, liquid or gas stored in the film from being dissipated. The heating temperature can be 120-350 ℃, especially 120-150 ℃, so as to take account of the time required for melting and bonding.

In order to achieve the above heating temperature enough to rapidly complete the sealing, the power of the heating wire 310 is preferably 3W to 7W, more preferably 3W. In the present invention, the setting of the power is important because the heating wire 310 must be formed with a very small crack enough to be quickly bonded to complete the sealing. Moreover, the correct setting of power can save the warm-up time for the user to wait. For this, the voltage of the heating wire 310 may be set to be 2.4V to 6.0V, preferably 2.4V to 3.0V. The heating wire 310 may be a round wire or a flat wire. If the heating wire 310 is a round wire, the diameter of the round wire can be set to be 0.16mm to 0.36mm, preferably 0.23mm to 0.34 mm; if the heating wire 310 is a flat wire, the wire diameter thereof may be set to be 0.4mm to 1.4mm, preferably 0.6 mm. The length of the heating wire 310 is inversely proportional to the square of the wire diameter of the heating wire 310. Specifically, the length of the heating wire 310 may be set to 30mm ± 10 mm. It is clear that scaling the above numerical ranges equally based on physical principles falls within the equivalent scope of the invention.

It should be noted that since the heating wires 310 are configured to instantaneously heat the region of the film and cool and bond the region within 1 second ± 0.5 second, the user holding the handheld rapid-heating film cutting bonder 1 of the present invention can smoothly complete the sealing by cutting across the film (from one side of the film to the other side of the film). Because the heating wire 310 of the present invention has a very high heating efficiency, it is considered to lay a soft pad (or, for example, two sheets of a4 photocopy paper) under or behind the plastic film to be cut and bonded so as to protect other objects. Even when a user scratches a plastic bag with the hand-held rapid heating film cutting bonder 1 of the present invention, the solid, liquid or gas contained in the plastic bag does not escape, which is very convenient and efficient. These effects have been confirmed experimentally.

In order to supply power to the power supply module 200 through the electric header assembly 300, the handheld rapid heating film cutting bonder 1 of the present invention may further include a first contact piece 210 and a second contact piece 220. In the embodiment of fig. 2, the first contact pad 210 is a dual contact pad connected to a first terminal 201 and a third terminal 203 of the power supply module 200. The two contacts of the dual-contact piece are electrically connected with each other, so that two batteries can be connected. The second contact pad 220 is a single contact pad, and is connected to a second end 202 and a fourth end 204 of the power supply module 200. The heating wire 310 of the electric socket set 300 is connected between the two connection points 221, 222 in the middle of the second connection point piece 220. Thus, a current loop can be formed. According to the principles of the present invention, a single contact piece and/or a double contact piece can be used to connect more cells in series or in parallel.

Next, the handheld rapid-heating film-cutting bonder 1 of the present invention may further include a switch spring 230 electrically connected between the power supply module 200 and the header assembly 300, and turning on or off power supply to the header assembly 300 according to pressure applied by the heating wire 310. Referring to fig. 2, when a user presses the handheld rapid-heating film-cutting bonder 1 of the present invention against a film (the film is usually placed on a table, etc.), the heating wire 310 is pressed to move toward the power supply module 200, thereby pressing the switch spring 230; then, the switch spring 230 makes the second contact piece 220 (especially the connection point 221) contact the second end 202 of the power supply module 200, so as to close the current loop and conduct the current loop. Therefore, the handheld rapid-heating film cutting bonder 1 of the present invention does not need to specially provide a switch on the housing 100, but directly uses the pressing action of the user as a switch, which is very convenient. However, to prevent the occurrence of the erroneous touch, the switch spring 230 may be set to have a trigger pressure value, and the power supply of the electric socket set 300 is turned on when the pressure through the heating wire 310 exceeds a pressure threshold value. Specifically, the trigger pressure value of the switch spring 230 may be 80cN ± 25 cN. cN refers to one hundredth of a newton (centinewton).

In addition, the handheld rapid thermal film cutting bonder 1 of the present invention may further include a protective cover 105 detachably sleeved on the front housing 103 and the front cover 104 to protect the heating wires 310 of the electric base assembly 300 from external physical damage or chemical erosion and prevent accidental contact.

Fig. 3 shows a perspective view and an open state view of the handheld rapid-heating film-cutting bonder 1 according to an embodiment of the present invention.

The handheld rapid-heating film-cutting bonder 1 of the present invention may be handheld or portable, and is preferably receivable in a pocket of clothes, as light as a lighter. Specifically, the maximum dimension in the longitudinal direction of the case 100 may be 80mm to 140mm, the maximum dimension in the width direction may be 40mm to 80mm, and the maximum dimension in the thickness direction may be 20mm to 40 mm.

In addition, as shown in fig. 3, a pivot may be provided between the upper case 102 and the front cover 104, so that the upper case 102 may be pivoted to be opened for battery replacement.

Fig. 4 shows an exploded view of a hand-held rapid-heating film-cutting bonder 1 'according to another embodiment of the present invention, and fig. 5 shows a perspective view and an open state view of the hand-held rapid-heating film-cutting bonder 1' according to another embodiment of the present invention.

As shown in fig. 4, in the present embodiment, the housing 100 'of the handheld rapid thermal film cutting bonder 1' includes a lower housing 101 ', an upper housing 102', a front housing 103 ', and a front cover 104'. Wherein, the lower shell 101 'and the upper shell 102' are embedded with each other through the insert and the embedding hole to form a rear shell module; the front housing 103 'and the front cover 104' are also embedded with each other by the insert and the embedding hole to form a front housing module. (wherein, the first contact piece, i.e. the double contact piece 210 in fig. 4 is slightly different in shape from the first contact piece, i.e. the double contact piece 210 in fig. 2, but has the same function.)

Next, referring mainly to fig. 5, a rear case module composed of a lower case 101 'and an upper case 102' and a front case module composed of a front case 103 'and a front cover 104' are fitted to each other with a concave portion and a convex portion. Therefore, the user can detach the front case module to replace the battery received in the rear case module. Moreover, the front shell module and the heating wires contained therein can be modularized, so that a user is allowed to replace the heating wires with different powers so as to adapt to films with different thicknesses or materials; when the heating wire is aged or broken, the old front housing module can be removed and replaced with a new one.

Fig. 6 is a schematic diagram illustrating a method of using a handheld rapid thermal film cutting bonder in accordance with an embodiment of the present invention.

The user operates the handheld rapid-heating film cutting bonder of the present invention, generally, the heating wire 310 is moved in a first direction to cross the film for cutting and bonding, in which case the action range of the heating wire 310 on the film is small; however, the heating wire 310 may be moved in the second direction to cross the film for cutting and bonding, in which case the heating wire 310 has a larger range of action on the plastic film, so that the heating wire can be moved in different directions for films with different thicknesses or materials. The first direction and the second direction are not parallel to each other, for example, perpendicular to each other, but not limited thereto.

The above-mentioned embodiments are intended to illustrate the objects, technical solutions and advantages of the present invention in further detail, and it should be understood that the above-mentioned embodiments are only exemplary embodiments of the present invention and are not intended to limit the present invention, and any modifications, equivalents, improvements and the like made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
