[0001] The utility model relates to the technical field of sealing machines, in particular to a sealing machine which can simplify the structure and reduce the volume. Background Art

[0002] In daily life, we see many packaged products of materials or mechanical parts. After bagging, these products are sealed with a sealing machine to complete the packaging operation. Traditional sealing machines have different designs according to different usage requirements, such as the hand-pressure sealing machine disclosed in the patent application with publication number TWM324033 and publication number TWM459185 and the pedal sealing machine disclosed in the patent application with publication number TWM506779. However, the aforementioned patents all have the problems of complex structure and large size, and there is still room for improvement in structure. Utility Model Content

[0003] In view of this, the main purpose of the present invention is to provide a sealing machine which can simplify the structure and reduce the volume.

[0004] In order to achieve the above main purpose, the sealing machine provided by the utility model includes a left base, a right base, a heater, and a pressing plate. The left base and the right base are arranged in a left-right relative manner, the left base having a left pivot hole, and the right base having a right pivot hole; the heater is straddled between the left base and the right base and is fixedly mounted on the left base and the right base with its opposite ends respectively; the pressing plate is located above the heater and has a left pivot and a right pivot, the left pivot of the pressing plate is pivotally mounted on the left pivot hole of the left base, and the right pivot of the pressing plate is pivotally mounted on the right pivot hole of the right base, so that the pressing plate can pivot up and down between an open position and a pressing position relative to the heater, when the pressing plate is located at the open position, the pressing plate is inclined relative to the heater to form an opening therebetween, so that an object to be sealed can be placed between the pressing plate and the heater through the opening, and when the pressing plate is located at the pressing position, the pressing plate and the heater abut against each other to fix the object to be sealed, so that the object to be sealed can be heated by the heater to complete the sealing.

[0005] From the above, it can be seen that the sealing machine of the utility model utilizes the configuration of the left and right bases to provide a supporting effect for the heater, and the user only needs to apply force to press down the pressure plate to complete the sealing of the object to be sealed. In other words, the sealing machine of the utility model is lighter in structure than traditional hand-pressure sealing machines or foot-operated sealing machines, and is relatively simple and easy to operate, thereby achieving the effect of simplifying the structure and reducing the size.

[0006] Optionally, a magnet is provided on at least one of the bottom surfaces of the left base and the right base, and the sealing machine can be adsorbed to a metal object (such as a refrigerator door) through the magnet so that it can be removed and used at any time.

[0007] Optionally, the right side of the pressing plate has a groove, the groove is provided with a torsion spring, the torsion spring has two legs, one of which abuts against the pressing plate, and the other abuts against the right base. In this way, the torsion spring provides elastic force to keep the pressing plate in the open position.

[0008] Optionally, a micro switch is arranged in the left base, and a transmission member is sleeved on the left pivot of the pressure plate. When the pressure plate is located in the open position, the transmission member moves away from the micro switch, causing the heater to stop heating; when the pressure plate is located in the pressed position, the transmission member triggers the micro switch, causing the heater to start heating.

[0009] Optionally, when the pressing plate is located at the pressing position, the top surface of the pressing plate does not protrude from the top surfaces of the left and right bases, so that the overall structure appears more concise.

[0079] See also Figure 1The sealing machine 10 of the present invention includes a left base 20 , a right base 30 , a heater 40 , and a pressing plate 50 .

[0080] like Figure 2 As shown, the left base 20 has a left base 21 and a left upper cover 26. The front side of the left base 21 has two left buckle grooves 22, and the front side of the left upper cover 26 has two left buckle parts 27. The left upper cover 26 is snapped into the two left buckle grooves 22 of the left base 21 by the two left buckle parts 27, so that the left upper cover 26 is assembled to the left base 21. In addition, the left base 21 has a first accommodating space 23 sealed by the left upper cover 26, and a micro switch 70 is arranged in the first accommodating space 23. The left upper cover 26 has a left positioning groove 28 connected to the first accommodating space 23 and a left pivot hole 29 located behind the left positioning groove 28.

[0081] like Figure 3 As shown, the right base 30 has a right base 31 and a right upper cover 36. The front side of the right base 31 has two right buckle grooves 32, and the front side of the right upper cover 36 has two right buckle parts 37. The right upper cover 36 is snapped into the two right buckle grooves 32 of the right base 31 by the two right buckle parts 37, so that the right upper cover 36 is assembled to the right base 31. In addition, the right base 31 has a second accommodating space 33 sealed by the right upper cover 36, and a control unit 80 is arranged in the second accommodating space 33. The right upper cover 36 has a right positioning groove 38 connected to the second accommodating space 33 and a right pivot hole 39 located behind the right positioning groove 38.

[0082] like Figure 2 and Figure 3As shown, the heater 40 has a support base 41, a heating wire base 42 and a heating wire 43. The support base 41 is a long strip structure made of aluminum extrusion, and the left end of the support base 41 has two left through holes 412, and two fixing screws S1 pass through the two left through holes 412 of the support base 41 and are locked to the two first left spiral tube parts 24 of the left base 21, so that the left end of the support base 41 is clamped to the left positioning groove 28 of the left upper cover 26 and fixed to the left base 21; similarly, the right end of the support base 41 has two right through holes 414, and two fixing screws S1 pass through the two right through holes 414 of the support base 41 and are locked to the two first right spiral tube parts 34 of the right base 31, so that the right end of the support base 41 is clamped to the right positioning groove 38 of the right upper cover 36 and fixed to the right base 31. In addition, the support base 41 has an embedding groove 416 extending along its length direction, and the heating wire seat 42 is embedded in the embedding groove 416 of the support base 41 in a tight fit manner and is flush with the two ends of the embedding groove 416. The heating wire seat 42 has a wire groove 422 extending along its length direction, and the heating wire 43 is arranged in the wire groove 422, and the left and right ends of the heating wire 43 both protrude outside the wire groove 422. The two ends of the heating wire 43 are clamped to the two gaskets 44 by two clamping screws S2, and the two clamping screws S2 are simultaneously inserted into the two copper pillars 45 and respectively locked to a second left spiral tube part 25 of the left base 21 and a second right spiral tube part 35 of the right base 31, so that the heating wire 43 can be stably maintained in the wire groove 422.

[0083] The pressing plate 50 is a plate-shaped structure made of aluminum extrusion. The pressing plate 50 is located above the heater 40. A pressing strip 54 is provided on the bottom surface of the pressing plate 50. A left pivot 51 and a right pivot 52 are respectively extended outward from the left and right sides of the pressing plate 50. The left pivot 51 of the pressing plate 50 is pivoted to the left pivot hole 29 of the left base 20, and the right pivot 52 of the pressing plate 50 is pivoted to the right pivot hole 39 of the right base 30, so that the pressing plate 50 can pivot up and down between an open position P1 and a pressing position P2 relative to the heater 40. When the pressing plate 50 is in the position as shown in FIG. Figure 1 In the open position P1 shown in FIG. 1 , the pressing plate 50 is inclined relative to the heater 40 to form an opening 12 therebetween. The object to be sealed (not shown) is placed between the pressing plate 50 and the heater 40 through the opening 12. Figure 6 In the downward pressing position P2 shown in FIG. 1 , the pressing plate 50 is in contact with the heating wire seat 42 of the heater 40 through the pressing strip 54, so that the sealed object is sealed under the heating effect of the heating wire 43. At this time, the top surface of the pressing plate 50 does not protrude from the top surface of the left and right upper covers 36, 46, making the overall structure more concise. In addition, a transmission member 55 is sleeved on the left pivot 51 of the pressing plate 50. When the pressing plate 50 is in the position shown in FIG. 1 , the pressing plate 50 is in the position shown in FIG. Figure 6 When the pressing plate 50 is in the downward pressing position P2, the transmission member 55 triggers a trigger member 72 of the micro switch 70 with a transmission part 552, so that the heating wire 43 starts to heat. Figure 4 In the open position P1 shown, the transmission part 552 of the transmission member 55 is away from the micro switch 70, so that the heating wire 43 stops heating. The temperature of the heating wire 43 is controlled by the control unit 80. Since how to adjust the temperature of the heating wire 43 is not the focus of this case, it will not be described in detail here.

[0084] Another example Figure 3 As shown, the right side of the pressure plate 50 has a groove 53, and a torsion spring 60 is arranged in the groove 53. The torsion spring 60 has a short leg 62 and a long leg 64. The short leg 62 abuts against the pressure plate 50. When a force is applied to press the pressure plate 50 downward, Figure 8 When the pressing plate 50 is in the downward pressing position P2 shown in FIG. 1 , the pressing plate 50 presses against the short leg 62 of the torsion spring 60, so that the torsion spring 60 accumulates elastic restoring force. When the external force on the pressing plate 50 is released, the elastic restoring force released by the torsion spring 60 will stretch the pressing plate 50 open until the long leg 64 of the torsion spring 60 abuts against a stopper 312 of the right base 31, and the pressing plate 50 is kept in the position shown in FIG. Figure 1 The open position P1 is shown.

[0085] It is necessary to add that, Fig. 9 As shown, a magnet 14 is disposed on the bottom surface of the left base 31 and the bottom surface of the right base 41. The magnet 14 can be used to adsorb the sealing machine 10 to a metal object (such as a refrigerator door) so that it can be removed and used at any time, thereby increasing the convenience of use.

[0086] As can be seen from the above, the sealing machine 10 of the present invention utilizes the configuration of the left and right bases 20, 30 to provide a support effect for the heater 40. The user only needs to apply force to press down the pressure plate 50 to complete the sealing of the object to be sealed. Compared with the traditional hand-pressure sealing machine or foot-operated sealing machine, the sealing machine 10 of the present invention is lighter in structure and relatively simple and easy to operate, thereby achieving the effect of simplifying the structure and reducing the size.
