Cartridge of packing machine

Abstract

The invention discloses a cartridge of a packing machine. The cartridge comprises a function point detecting mechanism, an inlet and outlet belt guide slot, a belt in-place detecting mechanism, a hot knife mechanism, an inlet and outlet belt motor, a fastening device, a belt, an inlet and outlet belt drive mechanism, a rack and a main shaft, wherein a plurality of cams are arranged on the main shaft; the function point detecting mechanism, the inlet and outlet belt guide slot, the belt in-place detecting mechanism, the hot knife mechanism, the fastening device and the inlet and outlet belt drive mechanism are connected on the rack; and the inlet and outlet belt motor is in transmission connection to the inlet and outlet belt drive mechanism through the belt. The cartridge is simple in structure, is relatively low in cost, and is simple and convenient to mount; the function point detecting mechanism only needs to check relative positions of a detecting plate and a proximity switch at a zero position, so that the checking is simple; and the inlet and outlet belt guide slot can be realized by a single hinge with a slot while the packing belt is not scrapped and galled. With the in-place detecting mechanism, time that the packing belt is in place is not required to be set, and the quality problems such as poor ironing and splicing effect of the packing belt or packing without belt due to the fact the belt is not in place, and the like are avoided.

Description

technical field [0001] The invention relates to a packing machine, in particular to a packing machine core. Background technique [0002] The structure of the baler movement on the market is complex, the cost is high, and the installation is very inconvenient. Moreover, the function point detection mechanism for the baler movement is difficult to adjust, and personnel with certain professional qualities are required; the in-out belt guide for the baler movement The belt groove generally adopts the blade opening and closing method. The bottom of the belt guide mechanism is connected to the cam of the main shaft. When the cam turns to a certain point, it will drive the parts in the belt guide mechanism to push the blades away. Returning to the initial position, the structure is complex, which is not conducive to debugging, and the blades in the process of feeding the belt are in a fixed state during use.

[0002] The structure of the baler movement on the market is complex, the cost is high, and the installation is very inconvenient. Moreover, the function point detection mechanism for the baler movement is difficult to adjust, and personnel with certain professional qualities are required; the in-out belt guide for the baler movement The belt groove generally adopts the blade opening and closing method. The bottom of the belt guide mechanism is connected to the cam of the main shaft. When the cam turns to a certain point, it will drive the parts in the belt guide mechanism to push the blades away. Returning to the initial position, the structure is complex, which is not conducive to debugging, and the blades in the process of feeding the belt are in a fixed state during use. Once the belt is pulled away, it is easy to scratch and pull the packaging belt; the core of the packaging machine does not have a belt position detection mechanism. It is necessary to set the time for the strapping belt to be in place, so that the feeding motor runs for the set time. If the quality of the strapping belt is unstable or other external factors may cause the feeding time to be completed, but the strapping has not been delivered to the designated position.

The connection position of the two ends of the packing tape is not well welded, and it is more likely that the front top knife cannot hold down the tape head. After the tape unwinding action is executed, the packing tape is all drawn back to the storage box, and the tape needs to be threaded again.

At the same time, the hot knife mechanism of the baler is generally a swing type and a straight-in type. The straight-line entry structure is too complicated, and the cost is relatively high. Generally, it is not used much. Although the swing type has a simple structure, it will cause damage to the hot knife, and the hot knife The contact surface with the packaging belt is small, which may easily cause the defect that only part of the packaging belt is scalded; the parts for adjusting the tightening force of the tightening device have high processing requirements, the adjustment curve is not linear, fine-tuning is not possible, and the structure is complex, which requires high requirements for the operator.
