Abstract
The novel automatic swing traction device is applied to a packaging bag bottom sealing machine, the outer diameter surface of an eccentric wheel is integrally formed with an outwards protruding traction weight, the bottom of a traction connecting block is integrally formed with a front pin stringing plate and a rear pin stringing plate, and the traction weight of the eccentric wheel is movably connected with the pin stringing plate of the traction connecting block through a pin shaft; the top of the traction connecting block is in fastening connection with the bottom shaft end of the vertical sliding shaft through a shaft sleeve; the front side surface of the vertical fixing plate is fastened with an upper linear bearing and a lower linear bearing through screws, and the upper linear bearing and the lower linear bearing are movably sleeved with the vertical sliding shaft at the same time; the eccentric wheel can drive the vertical sliding shaft to ascend/descend along the linear bearing through the traction connecting block. The eccentric wheel replaces the existing swing arm plate, so that the eccentric wheel can effectively avoid the problem of vibration of the whole machine.
Description
Technical Field
The utility model belongs to the field of bottom sealing machines, and relates to a novel automatic swing traction device applied to a packaging bag bottom sealing machine.
Background
The bottom sealing machine is also called a sealing and cutting machine, is mainly used for processing packaging bags, in particular to a vest type shopping bag for supermarkets, is mainly used for forming packaging bag bodies and sealing and cutting off bag bottoms, the name of the bottom sealing machine is also from the bottom sealing machine, at present, a swinging traction mechanism applied to the bottom sealing machine for packaging bags is mainly used for driving the bag body sealing mechanism to operate, the existing swinging traction mechanism adopts a swinging arm plate, and the swinging arm plate can vibrate due to large swinging inertia in the actual use process.
Disclosure of Invention
In order to solve the problems, the utility model provides a novel automatic swing traction device applied to a packaging bag bottom sealing machine, which is an important component part in the packaging bag bottom sealing machine, is matched with a bag body sealing mechanism for use, and can effectively avoid vibration of the whole machine during operation.
In order to achieve the above purpose, the utility model is realized by the following technical scheme: the novel automatic swing traction device applied to the packaging bag bottom sealing machine consists of an eccentric wheel, a traction connecting block, a vertical sliding shaft, a vertical fixing plate and a linear bearing, and is characterized in that,
an outward protruding traction weight is integrally formed on the outer diameter surface of the eccentric wheel, a first pin hole is drilled on the traction weight, a front pin stringing plate and a rear pin stringing plate are integrally formed at the bottom of the traction connecting block, a second pin hole is drilled on each pin stringing plate, and a gap between the front pin stringing plate and the rear pin stringing plate is used as a caulking groove;
the traction weight can be placed in the caulking groove upwards, the pin hole I and the pin hole II are aligned and then connected in series with a pin shaft, and the traction weight of the eccentric wheel is movably connected with a pin connecting plate of the traction connecting block through the pin shaft;
the top of the traction connecting block is in fastening connection with the bottom shaft end of the vertical sliding shaft through a shaft sleeve;
the vertical fixing plate is fastened on the frame through bolts, and an upper linear bearing and a lower linear bearing are fastened on the front side surface of the vertical fixing plate through screws and are symmetrically arranged;
the upper and lower linear bearings are movably sleeved with the vertical sliding shaft at the same time;
the eccentric wheel can drive the vertical sliding shaft to ascend/descend along the linear bearing through the traction connecting block.
The eccentric wheel is integrally formed with an eccentric shaft hole and an arc limiting hole through a casting process, the eccentric shaft hole of the eccentric wheel can be sleeved with the rotating shaft, and the rotating shaft realizes action through the driving mechanism.
The utility model has the beneficial effects that the eccentric wheel replaces the existing swing arm plate, so that the eccentric wheel can effectively avoid the problem of vibration of the whole machine.
The utility model is described in further detail below with reference to the accompanying drawings.
