Description

Technical Field

[0001] This utility model relates to a horizontal soft aluminum packaging machine, and more particularly to a heat sealing mechanism for a horizontal packaging machine. Background Technology

[0002] Flexible aluminum packaging offers excellent barrier properties, effectively blocking oxygen, optical fibers, water stains, moisture, impurities, and oil. It also boasts good airtightness and puncture resistance, making it suitable for food and pharmaceutical packaging. During packaging, to improve efficiency, materials are automatically fed through a vibrating disc into the space between heated rollers to seal with the flexible aluminum film. However, the vibrating disc continues to vibrate during sealing, which can result in unsealed bags containing either no material or multiple items. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a horizontal packaging machine heat sealing mechanism that is simple in structure, reasonable in design, has high heat sealing efficiency, and high material sealing accuracy.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a heat sealing mechanism for a horizontal packaging machine, including a main frame, two material receiving rollers on both sides of the main frame, a hot-press support frame between the two sets of material receiving rollers, two hot-press rollers on the hot-press support frame, a material dropping track on the upper side between the two sets of hot-press rollers on the main frame, a material dropping channel for material to pass through the material dropping track, and a material control component at the outlet of the material dropping channel inside the hot-press support frame. The material control component includes a servo motor and a material control shaft, and the material control shaft is rotatably mounted inside the hot-press support frame and is connected to... A servo motor is rotatably connected. An eccentric wheel is provided on the material control shaft. A material control bearing seat is provided in the hot press support frame corresponding to the material dropping track. The material control bearing seat is provided with a feeding plate and a stopping plate on both sides of the material dropping track via a material control slide rod. The feeding plate and the stopping plate are respectively provided with a feeding column and a stopping column at each material dropping channel on the side facing the material dropping track. An eccentric track plate is provided on the feeding plate and sleeved on the outside of the eccentric wheel. A hopper communicating with the material dropping channel of the material dropping track is provided on the upper side of the main frame. Two sets of air cooling knives are symmetrically provided on the lower side of the two sets of hot press rollers. Using the above structure, the eccentric wheel is driven to rotate rapidly by the servo motor, so that the feeding plate and the feeding plate make uniform parallel reciprocating motion, and the material is quickly put into the hot press roller forming mold one by one. Then, the difference in height between the material feeding track and the hot press roller is used again to make the material accurately enter the hot press roller bubble, which improves the heat sealing efficiency and avoids the situation of multiple pieces of material in one bubble.

[0005] Preferably, the main frame is equipped with a drive assembly for driving the hot press rollers to rotate. The drive assembly includes a limiting plate mounted on the main frame, a linear slide rail on the limiting plate, and two sets of connecting plates slidably mounted on the linear slide rail. Each set of connecting plates is equipped with a reducer and a drive shaft for driving the hot press rollers to rotate. The two sets of reducers are connected by a spline sleeve assembly. The main frame also has a heat-sealing drive motor that is connected to one set of reducers. Using this structure, two hot press rollers are synchronously driven to rotate by a single heat-sealing drive motor, improving hot pressing efficiency while simplifying the overall structure.

A hot-press adjustment motor is mounted on the main frame, and the hot-press adjustment motor is drively connected to one of the axles on the hot-press support frame. With this structure, the sealing strength of the material is ensured by adjusting the gap between the two hot-press rollers through the hot-press bearing seats.

[0007] Preferably, the axle is equipped with a transmission worm gear, and the hot-press support frame is rotatably connected to the hot-press bearing seat via a transmission screw. The end of the adjustment screw is fitted with a transmission turbine gear connected to the transmission worm gear, and the outer end of the axle is equipped with a handwheel. With this structure, the transmission worm gear and transmission turbine gear have self-locking properties at a certain angle. Utilizing this characteristic, the outer packaging substrate is subjected to uniform force under the action of the adjustment screw.

[0008] Preferably, the main frame is equipped with a track moving seat, and a horizontally arranged moving groove is opened on the side wall of the track moving seat. The material dropping track is slidably disposed in the moving groove via a linear bearing. The outer side of the track moving seat is equipped with a track positioning plate and a tension knob for locking the material dropping track. On the side of the track moving seat opposite to the material dropping track, there is a dust suction hood that communicates with the inner cavity of the material dropping track. With the above structure, the material dropping track can be easily replaced according to production needs, and the dust suction hood can clean the dust in the material dropping track, preventing dust from clogging the material dropping channel.

[0009] Preferably, the feeding posts on the feeding plate are positioned corresponding to the center of the material feeding channel, and each material feeding channel has two stop posts, which are located on the upper side of the feeding posts and corresponding to the two sides of the material feeding channel. This structure allows for rapid and precise control of the material throughput while preventing damage to the material.
