Description

Strong pincer type sealing machine

Technical Field

The utility model relates to a pliers and plastic packaging capper, especially hand vice formula capper.

Background

The hand-nipper type sealing machine comprises an upper handle, a lower handle, an upper pressure plate, a lower pressure plate and a heating device. When the bag sealing device works, the upper handle and the lower handle are continuously held by hand, so that the upper pressure plate and the lower pressure plate are closed to pressurize and seal the bag opening. Compare desk-top and foot-operated capper, the pincers formula capper uses more nimble convenience, but this kind of pincers formula capper exists obviously not enough: the sealing process needs to be performed with great effort, the handle needs to be continuously compressed with effort, the frequent sealing is easy to fatigue, and the sealing effect is different due to different hand gripping strengths. Although a normally closed pliers sealing machine can solve the problem of continuous force application, the sealing machine also needs to clamp once and loosen once and hold twice, is inconvenient to control by using a microswitch and has a complex structure.

When the bag mouth is plugged into the jaw of the existing sealing machines, the distance between a sealing line and the bag mouth is irregular due to poor holding of the depth position of the plugged jaw.

Disclosure of Invention

The utility model aims at providing a simple structure, laborsaving just need not continuously hold tightly hard to seal the unanimous pliers formula capper of specification parallel and level.

In order to achieve the above object, the utility model discloses in adopt locking pliers to replace hand vice, utility model relates to a pincers type capper energetically solves above-mentioned problem, and the locking pliers has utilized secondary lever principle, and is more laborsaving, moreover, can provide lasting sealing pressure for the heat-seal device after the locking, can adjust adjusting screw pole and respond to different thickness plastic bags or provide different snap-in forces. The utility model discloses energetically clamp type capper mainly includes locking pliers pincers body and electric heat closing device, and electric heat closing device is including installing upper and lower holding down plate etc. at the tooth portion of keeping silent.

Preferably, after the sealing process is finished, the quick-release handle needs to be manually pushed to open the jaw after the heat dissipation and cooling are carried out for a certain time, which is troublesome. Therefore, a magnetic repulsion device similar to the magnetic lock can be arranged on the handle of the large pliers near the connection of the movable handle and the labor-saving connecting rod, the thermistor is utilized to trigger the magnetic repulsion device to destroy the locking balance state of the large pliers sealing machine when the sealing temperature drops to a certain temperature, the large pliers sealing machine is loosened, and the upper pressing plate and the lower pressing plate are opened to prepare for the next sealing.

Preferably, because the opening range of the jaw is small, the plastic bag is soft, and the bag opening is not easy to be plugged into the jaw during sealing, the guide-in piece can be arranged on the outer side of the jaw pressing plate to enlarge the jaw, so that the bag opening is convenient to be plugged.

Preferably, the pocket mouth is plugged in a shallow depth and is not easy to master, so that the blocking sheets can be arranged on the inner side of the jaw lower pressing plate, and one end of each blocking sheet is arranged. When the bag opening is plugged into the jaw, the blocking piece can block the bag opening. Although the locking pliers hold the handle to block the mouth of the bag, it is farther apart and does not remain flush. The blocking piece is closer to the electric heating wire, so that the position of the bag opening sealing line is close to the edge of the bag opening and is flush and consistent after sealing each time.

Compared with the prior art, the utility model beneficial effect who has: simple structure can save the cost, and convenient operation is more laborsaving, seals the effect parallel and level unanimously.

The quick-release type thermal insulation clamp comprises a quick-release handle 1, a movable handle 2, a movable clamp head 3, a labor-saving connecting rod 4, a fixed handle 5, a fixed clamp head 6, an upper pressing plate 7, a lower pressing plate (heating plate assembly) 8, an I-shaped silica gel filler strip 9, a thermal insulation bakelite insulating plate 10, a heating wire 11, a guide piece 12, a blocking piece 13, a high-strength spring 14 and an adjusting screw rod 15

Detailed Description

In this embodiment, the upper and lower pressing plates are respectively installed on the fixed jaw and the movable jaw of the locking pliers, as shown in fig. 1 and 2. The tong head is designed into a T shape, two corners extend out of two ends of the transverse head of the T shape, and the tong head is connected and fixed with the pressing plate through bolts. Fig. 3 is a partial enlargement of the pliers head and the press plate, and the T-shaped head has holes at its longer corners for fastening with the holes at the top (bottom) of the press plate. In fig. 1, 2 and 4, the handles of the large power tongs are not shown with an insulating plastic sleeve, and the insulating plastic sleeve is used.

The power circuit of the sealing machine electric heating part is mature and universal regardless of direct heat or instantaneous heat, and detailed description is omitted here. In this embodiment, the lower pressing plate is a heating plate assembly electrically connected to the power supply. The lower pressing plate is paved with a heat insulation bakelite insulating backing plate, the bakelite plate is provided with a heating strip of an electric heating wire, and the heating strip is covered with a layer of insulating high-temperature-resistant cloth. The lower pressure plate or the clamp body can be provided with a micro switch, a thermistor, a working indicator light and other elements. The upper pressing plate is a pressing strip of an I-shaped silica gel pad, and for the double-sided heat sealing machine, the upper pressing plate is also designed into a heating plate.

Because the opening range of the jaw is limited, the plastic packaging bag is made of flexible materials, and the bag opening is not easy to be plugged into the jaw, so that the guide piece is added on the lower pressing plate.

In addition, to prevent the pocket of the tuck-in jaw from being too deep or too shallow, a stop is added on the other side of the lower platen to block the tucked-in pocket, as shown in FIG. 3.

The utility model discloses use the flow: the utility model discloses when sealing the plastic bag, adjust the corresponding temperature of time temperature appearance (regulation time of generating heat) control, open switch, put the plastic bag sack and fill in on the guide between top board and the holding down plate, it stops the piece until touch until inwards pushing, then the pressfitting seals pincers, top board and holding down plate can sticis together, start micro-gap switch, give control scheme board signal starting transformer by micro-gap switch and give the heating wire power supply and generate heat, time relay control heating time reaches and stops the transformer power supply by the circuit board after the setting value, the completion seals the plastic bag. At the moment, the quick-release handle can be manually pulled to open the jaw, if the magnetic repulsion device is installed, the jaw can be automatically flicked after the sealing temperature is reduced to a certain temperature or a certain time, and the microswitch is reset.

Although the embodiments of the present invention have been shown, it will be apparent to those skilled in the art that changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
