Description

Technical Field

[0001] This utility model relates to the field of condiment packaging technology, specifically a sealing device for bagging condiments. Background Technology

[0002] Sealing devices for seasoning bags are key equipment in the food packaging industry. They are mainly used to seal bags filled with powdered seasonings (such as salt, sugar, chicken essence, pepper, etc.). Seasoning sealing devices typically consist of a conveying system, sealing actuator, heat sealing module, pressing module, control system, and auxiliary components. Seasoning sealing devices are widely used in food processing plants, catering supply chains, and the retail industry.

[0003] For example, Chinese patent CN212149504U, entitled "A Sealing Device for Packaging Seasonings," includes a device installed above a conveying mechanism, with fixing clamps installed on both sides of the conveying mechanism and moving together with it; it includes a base, a fixing seat, a connecting rod, a bracket, a heating device, a sealing strip, a servo motor, a slide rail, a crank, a connecting rod, and a slider; the front of the base has two rows of vertical through holes, and the side of the base has a vertical through groove; the fixing seat is installed on the base, and the fixing seat has threaded mounting holes that mate with the through holes; the connecting rod is installed on the right side of the fixing seat, and the bracket is fixedly connected to the right side of the connecting rod; the heating device is installed on the bracket.

[0004] While the existing technologies can achieve packaging bag sealing, in practical use, on the one hand, it is difficult to quickly position the packaging bags. Usually, the operators place the packaging bags directly on the conveyor belt, making it difficult for the packaging bags to be placed in the right position, thus affecting the sealing efficiency of the packaging bags. On the other hand, the sealing effect of the bag body is not good enough. The bag body is usually sealed by pressing two heating strips against each other, which results in the lower heating strip being too low, causing the bag opening to face downwards, and the seasonings to move to the sealing position, thus reducing the sealing performance of the bag body. Therefore, it does not meet the current requirements. To address this, we propose a sealing device for seasoning bagging. Utility Model Content

[0005] The purpose of this invention is to provide a sealing device for packaging condiments, in order to solve the problems mentioned in the background art, such as the difficulty in quickly positioning the packaging bag and the insufficient sealing effect of the bag.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sealing device for bagging condiments, comprising an operating table, with frames fixedly installed at the four corners of the lower end of the operating table, and fixed seats fixedly installed at the upper ends of both sides of the front end of the operating table. A first hydraulic telescopic device is fixedly installed at one end of the fixed seat, the telescopic end of the first hydraulic telescopic device passing through the fixed seat and extending to the other end of the fixed seat. A movable plate is fixedly installed at one end of the telescopic end of the first hydraulic telescopic device, and an installation cavity is provided inside the movable plate. The installation cavity has an open structure, and a plurality of installation rods are fixedly installed inside the installation cavity. The installation rods are evenly distributed, and pulleys are provided outside the installation rods. The pulleys are rotatably connected to the installation rods, and one end of the pulleys is located outside the movable plate.

[0007] Preferably, the operating table has a telescopic cavity at its rear end, with an open structure at the top. An L-shaped fixing frame is fixedly installed at the upper end of the operating table at the rear end of the telescopic cavity opening. Heating strips are installed inside the telescopic cavity and below the horizontal plate of the L-shaped fixing frame. The heating strips inside the telescopic cavity slide in conjunction with the telescopic cavity.

[0008] Preferably, a third hydraulic telescopic device is fixedly installed at the rear ends of both sides of the lower end of the operating table, and the telescopic end of the third hydraulic telescopic device extends into the telescopic cavity and is fixedly connected to the heating strip.

[0009] Preferably, a conveying cavity is provided at the center of the operating table. The conveying cavity has an open structure. Several rotating rods are provided inside the conveying cavity. The front and rear ends of the rotating rods are rotatably connected to the conveying cavity, and the rotating rods are equidistantly distributed. A belt roller is fixedly provided outside the rotating rods, and a conveyor belt is sleeved on the outside of the belt roller.

[0010] Preferably, drive motors are fixedly installed on both sides of the outer front end of the operating table, and the output shaft of the drive motor extends into the interior of the conveying cavity and is fixedly connected to the rotating rod.

[0011] Preferably, a second hydraulic telescopic device is fixedly installed on both sides of the upper end of the L-shaped fixing frame horizontal plate, and the telescopic end of the second hydraulic telescopic device extends to the lower part of the L-shaped fixing frame horizontal plate and is fixedly connected to the heating strip.

[0012] Preferably, the vertical plate of the L-shaped fixing frame has two through holes inside, and the through holes correspond to the positions of the heating strips.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model can position the bag body through the first hydraulic telescopic device and the moving plate. Before the packaging bag sealing operation, the position of the moving plate is adjusted according to the packaging bag. At this time, the first hydraulic telescopic device is turned on, so that the telescopic end of the first hydraulic telescopic device extends. The extension of the telescopic end of the first hydraulic telescopic device drives the moving plate to move until the moving plate is moved to the appropriate position. When the packaging bag is placed, the front end of the packaging bag contacts the pulley on the moving plate, and the opening of the packaging bag is located between the heating strips. At the same time, under the action of the conveyor belt, the packaging bag slides over the pulley, thereby improving the efficiency of packaging bag placement.

[0015] (2) This utility model can adjust the position of the heating strip through the telescopic cavity and the third hydraulic telescopic device. Before the packaging bag sealing operation, the position of the heating strip is adjusted according to the opening position of the packaging bag. At this time, the third hydraulic telescopic device is turned on, so that the telescopic end of the third hydraulic telescopic device extends and retracts. The extension and retraction of the telescopic end of the third hydraulic telescopic device drives the heating strip to move until the heating strip is adjusted to a suitable position. At this time, the heating strip is located below the opening position of the packaging bag and does not contact the packaging bag. Then the subsequent conveyor belt operation is carried out to avoid the opening side of the packaging bag tilting downward during sealing, thereby improving the quality of packaging bag sealing.

[0016] (3) This utility model can seal multiple packaging bags by means of a conveyor belt and a drive motor. When sealing the packaging bags, the moving plate and the heating strip on the third hydraulic telescopic device have been adjusted to the appropriate position. At this time, the drive motor is turned on, so that the output shaft of the drive motor drives the rotating rods on both sides of the conveying chamber to rotate. The rotating rods drive the belt rollers to rotate. At this time, the conveyor belt outside the belt rollers moves under the action of the belt rollers. Then, the operator intermittently places the packaging bags containing seasonings on the conveyor belt, keeping the opening of the packaging bags in an inclined upward state. Under the action of the conveyor belt, the packaging bags are moved between the heating strips until the appropriate number of packaging bags are placed and the subsequent sealing operation is carried out, thereby improving the efficiency of packaging sealing.
