Abstract

An electric twist tie machine comprises a machine frame (1), a push rod (3) and a push rod drive mechanism comprising a push rod power portion (8) and a drive portion. The drive portion comprises a connection rod (4), a sliding piece, a sliding track (5), and a gear (7). The connection rod (4) is connected between the push rod (3) and the gear (7), and connected to the machine frame (1) via the sliding piece. The sliding piece is rotatably connected to a connection point between the connection rod (4) and the push rod (3). The machine frame comprises the sliding track (5) arranged horizontally for the sliding piece to slide thereon. The sliding track (5) and the push rod (3) are arranged on a same horizontal line. The gear (7) comprises a reinforcement bar (6) connecting from a rotation center of the gear (7) to a connection point connecting to the connection rod (4). The rotation center of the gear (7), the push rod (3), and the sliding track (5) are located on a same horizontal line. The electric twist tie machine is simple in structure, has small energy loss from the power portion to the push rod, and slightly reduces a power requirement of a motor, thereby saving power.

Description

Electric tie machine

Technical field

The invention relates to a packaging bag tying device, in particular to an electric tying machine.

Background technique

With the increasing popularity of various disposable bags, the tie machine is now widely used. The tying pinning machine is one of the tying machines. The tying pin is popular in the retail industry because of its difficult opening and environmental protection characteristics, and thus the zippering machine has become a lot of The most widely used type of tie machine. At present, the vast majority of the tying machines visible on the market are manual, and the main components of the manual tying machine are a bracket, a push rod and a crank rod, wherein the bracket is provided with a nail opening, and the nail opening is used for A tying nail is installed for tying the packaging bag; the push rod is used to push the tying nail and the zipper is made, and the crank lever is used as an operating handle of the tying machine, and is connected with the push rod drive. In use, the operator is required to carry a bag and the other hand pulls the crank lever to drive the pusher to move and complete the tie.

Patent No. CN201420322001.3 discloses an electric tying machine comprising a frame, a push rod and a push rod driving mechanism, the push rod driving mechanism comprising a power part and a transmission part, the power part comprising a motor and a transmission part The utility model comprises a crank, an intermediate connecting rod, an output connecting rod and an auxiliary connecting rod, wherein one end of the intermediate connecting rod is connected with the crank, the other end is respectively connected with the corresponding end of the output connecting rod and the auxiliary connecting rod, and the output connecting rod is connected with the push rod, and the auxiliary connecting is connected The rod is connected with the frame, and the output link and the auxiliary link are distributed in a V shape; the transmission part further comprises a reduction gear, the crank is assembled on the reduction gear, and the reduction gear meshes with the output gear provided on the motor. A disadvantage of one of the electric wire ties in this patent is that the transmission portion between the power portion and the push rod is too cumbersome and the energy loss during the period is large.

Summary of the invention

The technical problem to be solved by the present invention is to provide an electric wire lashing machine with large thrust, simple structure and energy saving.

In order to solve the above technical problem, the technical solution of the present invention is: an electric tying machine, which is innovative in that it comprises a frame, a push rod and a push rod driving mechanism, and the push rod driving mechanism includes a push rod power portion and a transmission In part, the transmission portion includes a connecting rod, a slider, a chute and a gear, the connecting rod is connected between the push rod and the gear, and is connected to the frame through a slider; the slider is rotatably connected to the connecting rod At the junction with the push rod, the frame has a horizontal chute for sliding the slider, the chute being on the same horizontal line as the push rod.

Further, the gear has a reinforcing strip from the center of rotation to the joint of the connecting rod.

Further, the center of rotation of the gear, the push rod and the chute are at the same horizontal line.

The advantages of the invention are:

(1) The transmission portion of the electric tying machine of the present invention has only four components, and has a simple structure, and the energy loss from the power portion to the push rod is small, and the power of the motor can be slightly reduced, thereby saving energy.

(2) Since the force is relatively small, the connecting rod is directly connected to the gear. Since the gear needs to drive the connecting rod to move, the presence of the reinforcing strip increases the strength of the gear.

(3) At the moment when the aluminum nails are nailed, the push rods, the connecting rods, the chutes and the reinforcing strips on the gears are on the same horizontal line, which can provide sufficient nailing force and sufficient mechanical strength.

detailed description

As shown in FIG. 1 , the present invention discloses an electric tying machine including a frame 1, a push rod 3 and a push rod driving mechanism. The frame 1 is a well-known part, and will not be described again. The push rod driving mechanism includes a push rod. The power portion 8 and the transmission portion, the power portion 8 is a prior art, and will not be described again; the transmission portion includes a connecting rod 4, a slider, a chute 5, and a gear 7, and the connecting rod 4 is connected between the push rod 3 and the gear 7. Connected to the frame 1 through a slider; the slider is rotatably connected at a joint of the connecting rod 4 and the push rod 3, and the frame 1 has a horizontal sliding slot 5 for sliding the slider, the sliding slot 5 and the push rod 3 is on the same horizontal line; the gear 7 has a reinforcing strip 6 from the center of rotation to the joint of the connecting rod 4; the center of rotation of the gear, the push rod 3 and the sliding slot 5 are at the same horizontal line, and when the aluminum nail is nailed, the push rod 3. The reinforcing bars 6 on the connecting rod 4 and the gear 7 are in the same horizontal line, which ensures the mechanical strength and strength of the transmission part.

The power part controls the breaking of the power part 8 through the control button 2. When starting, the power is first transmitted to the gear 7, and the gear 7 is rotated under the power driving, and the connecting rod 4 connected to the gear 7 is rotated together, and the connecting rod 4 passes. The slider sliding in the chute 5 converts the circular motion on the gear 7 into a linear motion, thereby pushing the push rod 3 to close; since the gear 7 is always performing a circumferential motion, the push rod is also reciprocating, aluminum The nail can be nailed and loosened.

The basic principles and main features of the present invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited by the foregoing embodiments, and that the present invention is only described in the foregoing description and the description of the present invention, without departing from the spirit and scope of the invention.
