Description

Sealing packaging machine for food container

Technical Field

The invention relates to a sealing and packaging machine for a food container,

in particular to a method for sealing and packaging an inlet of a food container filled with contents by using a film,

the container can be more accurately placed in a prescribed position,

it is also possible to make the heater unit for sealing the container uniformly move up and down all the time,

thus, the food container sealing and packaging machine can stably seal and package food containers without malfunction or defects.

Background

In general, when natural foods such as vegetables and fruits and foods cooked in the cooking industry such as restaurants are stored or distributed, in order to maintain freshness, temperature, cleanliness and the like of the foods,

a sealing packaging step of filling a plastic food container with food and sealing an entrance of the container with a film is required.

For this reason, sealing and packaging machines for food containers have been developed for use in which the container inlet is sealed with a film,

however, since the heater unit for sealing the film in the conventional food container sealing and packaging machine simply performs the sealing operation by the up-and-down movement of the cylinder or the cam,

therefore, a phenomenon may occur in which the heater unit is not properly maintained in a horizontal state and is brought into contact with the entrance of the container in a state of being inclined to a certain side, thereby causing a problem in that the entire entrance of the food container is not uniformly sealed and a part of the non-adhered portion is generated.

Further, in the conventional sealing and packaging machine for food containers, since a tray for inserting a container containing food into the sealing and packaging machine is inserted while being shaken from side to side, the food container cannot be accurately set to a predetermined position for sealing, and thus there is a problem that the sealing work is performed in a state of being set to one side.

In addition, although the present applicant has developed Korean registered patent No. 10-1812108, "sealing and packaging machine for containers", which solves most of the above problems,

but since the elevation plate for driving the heater unit to move up and down is operated by means of the roller bearing installed at the center portion and the eccentric cam in contact therewith,

therefore, when the ball bearing and the eccentric cam are not properly mounted to the center of the lifting plate or the lifting rod connected to the lifting plate and the insertion hole for inserting the lifting rod are worn during use or the tolerance between the lifting rod and the insertion hole is accumulated beyond the allowable range due to repeated use, the problem that the lifting plate cannot be smoothly operated and is not stopped occurs may occur.

In addition, since the motor for driving the elevating plate is mounted on the elevating plate and moves up and down simultaneously with the elevating plate,

therefore, at the time of initial driving of the motor, a load caused by the rotational force of the motor is superimposed on the above-mentioned wear and accumulated amount of the allowable tolerance and further aggravates the problem that the lifter plate cannot operate smoothly.

Content of patent

The present invention has been made to solve the above-mentioned problems occurring in the conventional food container sealing and packaging machine,

the purpose is to ensure that the heater unit for sealing the film can uniformly perform the sealing operation on the whole container inlet in a state of not deviating to one side by accurately maintaining the horizontal state and uniformly moving up and down.

Another object of the present invention is to accurately set a food container to a predetermined position where sealing is performed by stably inserting a tray for inserting the container containing food into a sealing and packaging machine in a state free from left and right shaking, thereby ensuring that sealing operation can be accurately performed.

Still another object of the present invention is to prevent malfunction due to wear or tolerance of a heater unit driving support shaft and a bearing housing and to ensure smooth operation thereof by allowing the heater unit driving support shaft of a heater unit driving part for driving a heater unit to move up and down and a heater unit driving part support plate connected thereto to move up and down in a more stable supported state.

Still another object of the present invention is to prevent a problem that a heater unit cannot be smoothly operated due to a load applied to a heater unit driving support shaft of the heater unit and a bearing housing into which the heater unit driving support shaft is inserted, which is caused by an initial rotational force of a motor.

The invention is characterized in that: the heater unit for sealing the film is driven by the 4 heater unit driving support shafts installed on the periphery to be in a horizontal state and uniformly moves up and down under the drive of the eccentric cam of the heater unit driving part, thereby preventing the bad phenomenon caused by the unbalance of the heater unit,

the tray for putting the container with food into the packaging machine is engaged with the guide device ┥ by means of the guide rail shaped like Contraband and is stably moved back and forth without shaking left and right, so that the food container can be more accurately set to a predetermined position for sealing and the sealing operation can be more accurately performed,

the heater unit driving support shaft of the heater unit driving part for driving the heater unit to move up and down and the heater unit driving part support plate connected with the heater unit driving part support shaft perform up and down movements in a state of being stably supported by the 2 roller bearings installed at the left and right side end parts and the 2 eccentric cams in contact therewith, thereby avoiding erroneous movements due to wear or tolerance of the heater unit driving support shaft and the bearing housing and ensuring smooth movements thereof,

the heater unit driving support shaft for driving the heater unit driving part and the motor for the heater unit driving part support plate to move up and down are fixedly installed on the bottom frame, so that the load caused by the initial rotating force of the motor is prevented from being directly transmitted to the heater unit driving support shaft and the bearing seat, and the heater unit driving part can be ensured to move smoothly.

The sealing and packaging machine for food containers to which the present invention is applied,

the heater unit for sealing the thin film is driven by 4 heater units installed on the periphery to form a horizontal state and uniformly move up and down, thereby preventing the bad phenomenon caused by the unbalance of the heater unit,

the tray for allowing the container containing food to enter the packaging machine can stably move back and forth without shaking left and right, thereby accurately sealing the food container at a predetermined position,

the heater unit driving support shaft of the heater unit driving part for driving the heater unit to move up and down and the heater unit driving part support plate connected with the heater unit driving part are stably supported to move up and down, thereby avoiding the error action caused by the abrasion or tolerance of the heater unit driving support shaft and the bearing seat and ensuring the smooth action,

by preventing the load caused by the initial rotating force of the motor for driving the heater unit driving support shaft of the heater unit driving part and the heater unit driving part support plate to move up and down from being directly transmitted to the heater unit driving support shaft and the bearing seat, the heater unit driving part can be ensured to move more smoothly.
