[0021] The following will clearly and completely describe the technical solution of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of this application.

[0022] The embodiment of the present application discloses a weight detection and screening device for aseptic brick filling. Figure 1 and Figure 2 A weight detection and screening device for sterile brick filling includes a conveyor platform 1 and a conveyor belt 2. A detection mechanism is provided on the conveyor belt 2, and a pushing mechanism is provided on the conveyor platform 1. The pushing mechanism is controllably connected to the detection mechanism. Specifically, the detection mechanism is provided on the surface of the conveyor platform 1 and is used to detect the weight of the sterile bricks on the conveyor belt 2. The stacking platform 3 is provided on the side of the conveying platform 1 away from the pushing mechanism, and the stacking platform 3 is fixedly connected to the end of the stacking platform 3 away from the pushing mechanism with a vertically arranged material blocking plate 31. A blanking port 32 is provided through the stacking platform 3, and a flap 4 is hinged in the blanking port 32. A collecting box 5 is provided below the blanking port 32. The upper opening area of ​​the collecting box 5 is larger than the area of ​​the blanking port 32. A limiting mechanism for limiting the flipping of the flap 4 is provided on the stacking platform 3, and a control mechanism for releasing the flipping restriction of the flap 4 by the limiting mechanism and realizing intermittent forward and reverse flipping of the flap 4 is provided on the stacking platform 3. Specifically, after the restriction of the flap 4 is released, the flap 4 is controlled to rotate forward once to put the unqualified products on the flap 4 into one side of the collection box 5, and then reversed to put the unqualified products on the flap 4 into the other side of the collection box 5.

[0023] Specifically, refer to Figure 1 and Figure 2 The limiting mechanism includes a push rod 61 that horizontally passes through the baffle plate 31, and a linkage frame 62 is fixedly connected to the end of the push rod 61 away from the pushing mechanism. Two limiting rods 63 parallel to the push rod 61 are fixed to the linkage frame 62. The limiting rod 63 is located at the lower end surface of the flip plate 4 to limit the flipping of the flip plate 4, and the projection length of the push rod 61 on the flip plate 4 is greater than the projection length of the limiting rod 63 on the flip plate 4; an elastic member 64 is provided between the linkage frame 62 and the baffle plate 31. When the limiting rod 63 moves to a position away from the bottom of the flip plate 4, the elastic member 64 is in a deformed state, and the elastic member 64 is specifically a tension spring sleeved on the push rod 61, and one end of the elastic member 64 is fixed to the baffle plate 31 and the other end is fixed to the linkage frame 62. When the unqualified products on the flap 4 squeeze the push rod 61, the limit rod 63 moves away from the flap 4 and puts the elastic member 64 into a deformed state. After the unqualified products fall into the collection box 5, the linkage frame 62 is driven by the deformation force of the elastic member 64 to move the limit rod 63 to the lower end surface of the flap 4.

[0024] When the unqualified products on the stacking platform 3 are piled up to the set number, the unqualified products squeeze the push rod 61 to make the linkage frame 62 move in the direction away from the material blocking plate 31, and then the linkage frame 62 drives the limit rod 63 away from the lower end surface of the flip plate 4, and under the action of the control mechanism, the flip plate 4 first flips forward, and a set number of unqualified products can be put into one side of the inside of the collection box 5; when the unqualified products on the stacking platform 3 are piled up to the set number again, the flip plate 4 flips toward the other end under the action of the current controller to make the unqualified products fall into the other side of the collection box 5, effectively reducing the need for stacking of unqualified products in the collection box 5, reducing the space occupied by unqualified products in the collection box 5, and alleviating the workload of operators in subsequent processes.

[0025] Further, refer to Figure 1 and Figure 2 The control mechanism includes a control plate 611 fixed to the free end of the push rod 61 and an electromagnet 71 installed on the upper end surface of one of the limit rods 63. The control plate 611 is arranged vertically. A magnet 72 is provided at the position of the flip plate 4 corresponding to the electromagnet 71, and the electromagnet 71 is connected to a current controller. The current controller is configured to alternate the current passing through the electromagnet 71, so that the electromagnet 71 generates an attractive force and a repulsive force on the magnet 72, thereby effectively realizing the alternating flipping of the flip plate 4.

[0026] Specifically, when the unqualified products push the control plate 611 to drive the push rod 61 to move toward the side away from the conveyor platform 1, the electromagnet 71 first generates suction on the limit rod 63 provided at this time, so that the flip plate 4 has a tilted posture to one side; when the unqualified products on the flip plate 4 reach the set number, that is, when the control plate 611 moves to between the flip plate 4 and the material baffle plate 31, the flip plate 4 can be flipped in the direction of its tilted posture to make the unqualified products on the flip plate 4 fall off, at this time the control plate 611 always contacts the side of the flip plate 4 close to the material baffle plate 31; when the flip plate 4 is reset to horizontal, the deformation force of the elastic member 64 pushes the push rod 61 and the control plate 611 to reset, at this time the current controller changes the direction of the current passed into the electromagnet 71, so that the flip plate 4 has a tilted posture to the other side, and this cycle can realize that the unqualified products on the flip plate 4 slide alternately to the two sides of the collection box 5, so as to reduce the probability of unqualified products piling up on one side and affecting subsequent processing.

[0027] And, refer to Figure 1 and Figure 2The flap 4 is fixedly connected to a shaft 41 that is rotatably mounted on the stacking platform 3. Below the stacking platform 3, guide plates 1 51 and 2 52 are symmetrically fixed to the shaft 41. Both guide plates 1 51 and 2 52 are tilted, with the side near the center of the flap 4 being higher. When the flap 4 flips toward guide plate 1 51, unqualified products fall through guide plate 1 51 into one end of the collection box 5. When the flap 4 flips toward guide plate 2 52, unqualified products fall through guide plate 2 52 into the other end of the collection box 5. Furthermore, a torsion spring 42 is provided at the hinged connection between the flap 4 and the dropout opening 32. When the flap 4 flips, the torsion spring 42 is deformed. After unqualified products fall into the collection box 5, the torsion spring 42 returns to its original position under the force of the torsion spring 42, causing the flap 4 to close the dropout opening 32, thus enabling the flap 4 to automatically reset after flipping.

[0028] Further, refer to Figure 1 and Figure 2 The pushing mechanism includes a first cylinder 81 fixed to one side of the conveyor platform 1 and arranged along the width direction of the conveyor belt 2. A push plate 82 is fixed to the piston rod of the first cylinder 81. Partitions 83 are provided on both sides of the push plate 82 in the height direction facing the detection mechanism, and the partitions 83 are fixed to the push plates 82 in an outward-facing "X" structure. The provision of the partitions 83 prevents the pushing mechanism from pushing unqualified products away from the pushing mechanism when pushing them. Baffles 33 are provided on both sides of the stacking platform 3 and the conveyor platform 1 at right angles, and the inner spacing of the baffles 33 on both sides of the stacking platform 3 is greater than the outer spacing of the pushing mechanism. This arrangement effectively enables the pushing mechanism to smoothly push unqualified products to the stacking platform 3, preventing unqualified products from tipping over or falling.

[0029] And, refer to Figure 1 and Figure 3 A support plate 92 is provided at the lower end of the collection box 5, and a cylinder 2 is vertically fixed to the middle of the lower end surface of the support plate 92. When a certain number of unqualified products are piled up in the collection box 5, the support plate 92 moves along the vertical direction of the cylinder 2, so that the collection box 5 is away from the stacking platform 3, so that when the next batch of unqualified products falls from the drop port 32, they can accurately fall into the empty part of the collection box 5, thereby realizing the automatic stacking and packing of unqualified products, improving the problem of disorderly stacking taking up a large space and requiring manual secondary sorting during the collection process of defective products, which consumes manpower.

[0030] The implementation principle of the weight detection and screening device for aseptic brick filling in the embodiment of the present application is as follows:

[0031] When the detection mechanism detects unqualified products, it controls the pushing mechanism to start and push the unqualified products to the stacking table 3. When the unqualified products on the stacking table 3 are accumulated to a set number, the unqualified products squeeze the control plate 611 and the push rod 61 to make the limit rod 63 away from the lower end face of the flap 4. Under the action of the current controller, the flap 4 flips toward one end so that the unqualified products fall into one side of the collection box 5; when the unqualified products on the stacking table 3 are accumulated to a set number again, the flap 4 flips toward the other end under the action of the current controller so that the unqualified products fall into the other side of the collection box 5. Then, under the action of cylinder 2, the support plate 92 drives the collection box 5 to move downward, which effectively reduces the unnecessary stacking of unqualified products in the collection box 5, reduces the space occupied by unqualified products in the collection box 5, and reduces the workload of operators in subsequent processes.
