[0002] A plastic lunch box is a disposable container for holding food. With the rapid development of the takeout industry, its usage has also increased dramatically. In the process of packaging the plastic lunch box after processing, in order to increase the convenience and neatness of subsequent stacking and placement, a guide device is required to guide the finished lunch box during transportation by a conveyor belt, so as to avoid displacement, offset and tilt. However, when the existing guide device is in use, its guide plate and the fixed mounting plate are mostly fixedly connected. Therefore, when in use, the guide gap between the two guide plates cannot be adjusted according to the model of the lunch box, and the overall applicability is poor. In addition, since most lunch boxes are trapezoidal structures that are wide at the top and narrow at the bottom, when in use, the existing guide device can only guide the lower end or the upper end of the lunch box alone, and cannot guide the lower end and the upper end of the lunch box at the same time, resulting in poor overall guiding effect in actual use. Therefore, in order to solve the above problems, it is necessary to develop a guide device for stacking and packaging plastic lunch boxes that is convenient to adjust, has good use effect and strong applicability.

[0018] When the utility model is used, first, the two guide members 0 are fixedly installed to the two sides of the conveyor in a symmetrical shape by using the fixed connection between the fixing bolts 11 in the two guide members 0 and the conveyor mounting frame, and then, the guide gap a formed by the cooperation of the guide plates 3 in the two guide members 0 is adjusted according to the width of the upper end of the lunch box to be guided. The specific adjustment operation is as follows: by controlling the unfolding length of the electric push rod a5, the thrust of the electric push rod a5 on the guide plate 3 inward when the electric push rod a5 is unfolded can drive the guide plate 3 to move horizontally, and then through the guide plate 3 By means of the lateral movement, the size of the guide gap a formed by the cooperation of the guide plates 3 in the two guide members 0 can be adjusted. With this structure, the utility model can be adapted to the guide use of different types of lunch boxes through adjustment, thereby increasing its applicability. After the guide gap a is adjusted, the electric push rod b63 can be controlled to contract, and the pulling force of the electric push rod b63 on the middle connecting plate 62 when the electric push rod b63 contracts can be used to drive the middle connecting plate 62 to move horizontally, thereby driving the cross bar 61 and the guide block 6 to move horizontally through the movement of the middle connecting plate 62. The guide block 6 is moved horizontally, and then the guide wheel 65 in the inner side groove 64 is driven to move by the movement of the guide block 6, so as to adjust the guide gap b formed by the cooperation of the guide wheels 65 in the two guide members 0, so that the guide gap b matches the width of the lower end of the lunch box to be guided; after completing the above operation, the lunch box can be transported by the conveyor belt in the conveyor, and in the process of moving the lunch box, the two expansion plates 4 are used to cooperate with the auxiliary guiding effect of the lunch box, so that the lunch box can smoothly enter the guide gap a formed by the two guide plates 3. At this time, Since most existing lunch boxes are trapezoidal structures that are wide at the top and narrow at the bottom, the guide gap a formed by the cooperation of the two guide plates 3 can guide the upper end of the lunch box, and the guide gap b formed by the cooperation of the two guide wheels 65 can guide the lower end of the lunch box. With this structure, the guiding effect of the lunch box can be improved through the cooperation of the guide gap a and the guide gap b, so that the position of the lunch box can be more accurate after the guidance is completed, and the operability of subsequent stacking of lunch boxes is increased; in general, the utility model has the advantages of convenient adjustment operation, good use effect and strong applicability.
