In this embodiment, the axis of the second synchronous belt wheel is parallel to the sliding direction of the first horizontal slide table. A second synchronous belt 3203 is provided between the two second synchronous belt wheels 3202. The moving direction of the second synchronous belt 3203 is parallel to the sliding direction of the material supporting slider, that is, the connection line of the two second synchronous belt wheels is perpendicular to the horizontal plane.

The connecting portion includes a fixed clamp block and a moving clamp block, which are used to clamp the second synchronous belt, thereby realizing the fixed connection with the second synchronous belt.

[0040] In order to enable the material supporting rod to quickly disengage from the rubber band, in this embodiment, a push rod cylinder 3207 is provided inside the material supporting slider. The push rod cylinder is horizontally arranged, and its output end faces the rubber band feeding station. The output end of the push rod cylinder is connected to the material supporting rod 3208 and is used to drive the material supporting rod 3208 to move axially. The length direction of the material supporting cylinder is parallel to the sliding direction of the first support plate. At the same time, the sliding direction of the material supporting rod 3208 is parallel to the sliding direction of the first support plate 3102. After the binding is completed, through the quick action of the push rod cylinder, the quick movement of the material supporting rod can be realized, that is, the material supporting rod can be quickly removed from the rubber band, avoiding the situation that the material tray shakes due to friction with the material tray caused by too slow speed, thereby improving the reliability and stability of the overall movement. In order to facilitate the picking of the rubber band of the rubber band feeding mechanism, in this embodiment, a connecting block 32071 is fixedly connected to the output end of the push rod cylinder 3207. The connecting block 32071 is a strip-shaped structure, which is horizontally arranged and the end faces inward (towards the material supporting area).

[0041] To facilitate the installation of the push rod cylinder, a push rod cylinder seat 32011 is provided inside the third mounting seat. The push rod cylinder seat 32011 is L-shaped, and the push rod cylinder is fixed on the push rod cylinder seat 32011. Its output shaft passes through the push rod cylinder seat 32011 and is connected to the connecting block 32071.

[0042] The carrier table 33 is arranged on the movement path of the material supporting area, that is, the rubber band in the material supporting area can be buckled onto the stacked trays on the carrier table, thereby realizing packaging. The carrier table 33 includes a horizontally arranged carrier table body and a fifth driving motor 331 for driving the carrier table body to rotate horizontally. It is used to drive the carrier table body to rotate 90 degrees. In this embodiment, the carrier table body is rectangular, and its length and width dimensions are smaller than the length and width dimensions of the tray. When the trays are stacked on the carrier table body, the edges of the trays are located outside the carrier table, and the exposed part is used for tying the rubber band. Therefore, the rubber band will not interfere with the carrier table.

[0043] The working principle of the rubber band tying mechanism for tray packaging in this application is briefly described below;

[0044] S1. Stack the trays on the carrier table body. After the detection sensor detects the trays, a material tying signal is triggered;

[0045] S2. The first support plate 3102 moves towards the rubber band feeding station. During the movement, the two third mounting seats approach each other. At the same time, the upper material supporting slider and the lower material supporting slider approach each other, that is, the four material supporting rods approach each other, so that the distance between each two is smaller than the size of the rubber band on the rubber band rack 29, and then the material supporting rods can enter the rubber band;

[0046] S3. When the material supporting rods enter the specified rubber band, the two third mounting seats move away from each other. At the same time, the upper material supporting slider and the lower material supporting slider move away from each other, that is, the four material supporting rods move away from each other, stretching the rubber band so that its size is larger than the size of the rubber band rack, and then separating from the rubber band rack;

[0047] S4. The first support plate 3102 moves in the reverse direction, moving towards the carrier table until the trays on the carrier table are located inside the stretched rubber band;

[0048] S5. The two third mounting seats approach each other. At the same time, the upper material supporting slider and the lower material supporting slider approach each other, that is, the four material supporting rods approach each other, so that the distance between the upper and lower is smaller than the thickness of the stacked trays, and the distance between the left and right tends to be the thickness of the trays, and then the rubber band is buckled to the outside of the trays. At this time, the push rod cylinder acts to pull out the material supporting rods inside the rubber band, realizing the separation from the rubber band;

[0049] S6. The material supporting rods are reset to perform the rubber band tying process for the next rubber band.

[0050] The rubber band tying mechanism for tray packing of the present utility model adopts a slide table structure, which is compact in structure, has a long stroke, can move between different workstations, is convenient for material taking and tying, has high moving efficiency and good stability; the synchronous belt is used to drive two mounting seats, which can realize the synchronous approach or separation of the two mounting seats, has good symmetry, realizes the symmetric stretching of the rubber band, avoids uneven stretching resulting in tray offset, improves the tying accuracy, and has good tying stability and high reliability; the material supporting slider is driven by a synchronous belt and a cylinder, which can effectively monitor and control the tension of the rubber band. At the same time, it can reduce its overall height and improve the compactness of the overall structure; a push rod cylinder is set, which can increase the extraction speed of the material supporting rod, realize the rapid separation from the rubber band, and avoid the tray shaking or offset caused by friction; the rubber band tying mechanism for tray packing of the present utility model is compact in structure, can realize the automatic material taking and tying of the rubber band, has high tying efficiency and good effect, and is suitable for batch packing of trays.

[0051] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
