Description

Technical Field

[0001] The utility model relates to the technical field of black pearl packaging, in particular to a hot plastic sealing device for black pearl packaging. Background Technique

[0002] Black pearl is a kind of food that is easy to get damp. If the packaging is not well sealed, it is easy to cause the food to get damp and deteriorate, affecting its taste and shelf life. Therefore, ensuring the tightness of the packaging bag is of great significance for maintaining the quality of black pearls and extending the shelf life.

[0003] At present, the surface of the common black pearl packaging hot plastic sealing device on the market is easy to warp or wrinkle before hot plastic sealing, resulting in the edges not being completely aligned during encapsulation, and causing the phenomenon of unsealing or leakage at the encapsulation edge. This is because the packaging bag is prone to deformation during transportation and positioning, and the existing encapsulation devices mostly rely on manual plastic sealing or simple mechanical flattening, which cannot effectively solve these problems.

[0004] Therefore, there is an urgent need for a hot plastic sealing device for black pearl packaging to solve the above-mentioned technical defects. Content of the Utility Model

[0005] The purpose of the utility model is to provide a hot plastic sealing device for black pearl packaging to solve the problems of a hot plastic sealing device for black pearl packaging mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A hot plastic sealing device for black pearl packaging, including a frame body and a fixed seat. The fixed seat is arranged below the frame body. The top end of the fixed seat is fixedly connected with a lifting cylinder. The output end of the lifting cylinder is fixed with a lifting rod. The bottom end of the lifting rod is fixedly connected with a steering motor. The bottom end of the steering motor is fixedly connected with a turntable. Each of the front and rear ends of the turntable is hinged with a set of movable arms. The other sides of the movable arms are respectively hinged with hinge seats. The hinge seats are fixedly connected with fixed arms. The bottom end of the fixed arm is fixedly connected with a push block.

[0007] Preferably, connecting rods are respectively fixedly connected to the outer sides of the fixed arms. Tracks are respectively opened on both sides of the top end of the frame body. The top ends of the connecting rods are equipped with balls. The balls are embedded in the tracks and form a rolling connection with the tracks.

[0008] Preferably, there are two sets of turntables and they are kept parallel. The cross-section of the turntable is diamond-shaped.

[0009] Preferably, the push block and the fixed arm are fixedly connected by bolts. The two push blocks form a symmetrical structure with respect to the center point of the lifting rod.

[0010] Preferably, a conveyor frame is provided below the frame body. A transmission motor is fixedly connected to the left side of the conveyor frame. A belt conveyor is assembled at the conveyor frame, and packaging bags are conveyed above the belt conveyor.

[0011] Preferably, a set of pressing cylinders are fixedly connected to both sides of the top end of the frame body. The output ends of the pressing cylinders are respectively provided with piston rods. The bottom ends of the piston rods are fixedly connected with heat insulation blocks. The bottom ends of the heat insulation blocks are fixedly connected with an upper frame. A lower frame is assembled at the bottom end of the upper frame. Heat melting rods are arranged at the edges of the heat insulation blocks and the lower frame.

[0012] Preferably, a plurality of springs are fixedly connected between the upper frame and the lower frame. The upper frame and the lower frame have the same size and corresponding positions in the vertical direction.

[0013] Preferably, a heating control device is fixedly connected to the middle position of the top end of the frame body. The heating control device is electrically connected to the upper frame.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: This black pearl packaging heat shrinkage sealing device not only realizes surface flattening before heat shrinkage sealing, achieving better flattening stability, but also avoids the impact on the belt conveyor caused by rapid impact and over-pressing.

[0015] (1) By providing a lifting cylinder, a lifting rod, a turntable, a steering motor, a movable arm, and a pushing block, the packaging bag above the belt conveyor is conveyed downward below the lower frame. When the packaging bag reaches below the lower frame, the lifting cylinder drives the lifting rod to descend, driving the pushing block to press down the packaging bag. At the same time, the steering motor is started, the turntable rotates clockwise in the horizontal direction, and the movable arm unfolds outward, thereby driving the two pushing blocks to contact the packaging bag and push it outward until the surface is smoothed. Then, the heat melting rod at the lower frame presses down the edge of the packaging bag to complete heat shrinkage sealing. By flattening the surface before heat shrinkage sealing, it is possible to avoid the situation where the edge cannot be aligned during heat shrinkage sealing due to surface warping or wrinkling, and avoid leakage of sealing.

[0016] (2) By providing a movable arm, a ball, a track, and a pushing block, when the two movable arms move outward, the ball at the top end of the connecting rod is embedded in the track, ensuring the smooth movement of the pushing block while converting the moving connection into a rolling connection, and having better flattening stability.

[0017] (3) By providing a heating control device, a heat melting rod, a lower frame, an upper frame, and a spring, the heating control device is electrically connected to the heat melting rod. By quickly heating the heat melting rod to the specified temperature, the high temperature required for heat shrinkage sealing can be provided. When the lower frame descends, the spring between the lower frame and the upper frame can play a buffering role, avoiding the impact on the belt conveyor caused by rapid impact and over-pressing.
