[0024] The upper trough 4 and the lower trough 5 are provided with an inlet 6 for the material receiving box to enter on one side, and an outlet 7 for the material receiving box to exit on the other side. New blank material boxes enter the upper trough 4 and the lower trough 5 through the inlet 6 to replace the old material boxes that are already full, and the old material boxes are discharged to the collection box through the outlet 7.

[0025] A material box picking and placing mechanism is provided between the upper support base 1 and the lower support base 2, which is used to transport the receiving material box in the material box compartment to the upper trough 4 and the lower trough 5 through the inlet 6.

[0026] A top fixing block 9 is movably installed at the bottom of the lower trough 5. The top fixing block 9 is connected to a top fixing drive component 10 for driving the top fixing block 9 to reciprocate in the lower trough 5 toward the opening of the lower trough 5. The top fixing drive component 10 is connected to the top fixing block 9 and is used to drive the top fixing block 9 to reciprocate in the lower trough 5 toward the opening of the lower trough 5 to the following two states: State one is that the top fixing block 9 is hidden at the bottom of the lower trough 5, providing clearance for the material receiving box to move in the lower trough 5; State two is that the top fixing block 9 moves forward to abut against the material receiving box between the top fixing block 9 and the bottom of the upper trough 4, at which time the opening of the material receiving box is close to the through opening 8.

[0027] In this embodiment, when the material box needs to be replaced, the material box picking and placing mechanism carries the new material box (along...). Figure 4 As shown in direction B, the material enters the upper groove 4 and lower groove 5 parallel to the inlet 6. During the entry process, the top fixing block 9 is hidden at the bottom of the lower groove 5. Figure 2As shown, the bottom of the material box slides into the lower groove 5 close to the bottom of the groove 5; after reaching the preset position, the top fixing drive 10 drives the top fixing block 9 to move forward until the receiving material box 18 abuts against the top fixing block 9 and the bottom of the upper groove 4. Figure 3 As shown, at this time, the opening of the receiving box 18 is close to the opening 8, used to receive the material sheet conveyed by the feeding channel 3. The material sheet (along the...) Figure 3 As shown in direction A, the material enters the receiving box 18 through the feeding channel 3 and the opening 8. After the box is full, the feeding channel 3 stops feeding, and the above-mentioned box replacement action is repeated. During the box replacement process, the box picking and placing mechanism carries the new box to the preset position while extruding the old box through the outlet 7 and into the product collection box located at the outlet 7.

[0028] In a preferred embodiment of this utility model, the material box picking and placing mechanism includes a clamping member 11 for clamping the receiving material box. The clamping member 11 is slidably connected to a linear slide rail 12 located below it via a slider. The sliding direction of the slider is the same as the input direction of the receiving material box. In this embodiment, the clamping member 11 includes two grippers 15 arranged along the direction of the receiving material box. The grippers 15 have a groove 16 in the middle for placing the receiving material box, and the receiving material box can move along the length direction of the material box within the groove 16. A fixed seat 14 and a lifting cylinder 13 are provided on the lower side of the linear slide rail 12.

Figure 7 As shown, the lower part of the material box compartment 20 is provided with a side outlet 17, which corresponds to the inlet 6 on the same horizontal plane. The clamping member 11 parallelly removes the bottom receiving material box 18 and carries it into the upper groove 4 and lower groove 5 through the inlet 6. When it reaches the preset position, the top fixing block 9 performs the above-mentioned clamping action on the material box (during the clamping process, the material box slides in the groove 16). After clamping, the clamping member 11 moves down with the linear slide rail 12 under the action of the lifting cylinder 13 and returns to the material box compartment 20 to start the next round of action. The whole process realizes the automation of material box switching.
