A high-speed detection electric eye is arranged at the end of the second belt conveyor 14, which is used to detect the timing of the materials entering the material collection device 2.

[0030] In this embodiment, the transmission speed of the second belt conveyor 14 is 20%-30% faster than that of the first belt conveyor 13 according to the length of the materials. In other embodiments, other ratios, such as 30%-40%, etc., can also be used.

[0031] The material collection device 2 realizes the accurate collection of the materials through the chain 150 transmission and the push rod structure. Specifically, it comprises:

[0032] 1. The support table 100: as shown in the figure, a plurality of straight sliding rails 160 and a base plate 110 in the form of an L-shaped plate structure are arranged in parallel on the upper surface of the support table 100. The base plate 110 is slidably connected to the two straight sliding rails 160 by a sliding block. The support table 100 further comprises a first driving device. The first driving device comprises a ball screw 190 and a first motor 400. The ball screw 190 is arranged on the upper surface of the support table 100 and connected to the base plate 110.

[0034] It should be noted that the left and right directions in the following are based on the direction of the material moving on the second belt conveyor 14. The left direction is the left side of the moving direction of the second belt conveyor 14, and the right direction is the right side of the moving direction of the second belt conveyor 14.

[0035] In this embodiment, two adjacent first push rods 151 form a material grid. When the high-speed detection electric eye detects that the material is injected into an empty material grid, a signal is emitted to control the chain 150 to continue moving. At this time, the material collecting device 2 is actuated, that is, the material grid on one side of the material inlet moves left as a whole to leave a grid, facilitating the injection of the next material into the next material grid.

[0036] In this embodiment, a stop block 161 is provided at both ends of the two straight sliding rails 160 to prevent the base plate 110 from derailing.

[0037] In this embodiment, a proximity switch 162 is installed on the side of the sliding rail to limit the movement of the ball screw 190 within the allowable range of travel, preventing the base plate 110 from moving too far and causing device failure.

[0038] Preferably, the proximity switch 162 is linked with an emergency stop circuit, which controls the power supply to be turned off when the device fails, such as the base plate 110 derailing, etc., enhancing the safety of the embodiment.

[0039] In this embodiment, a second baffle 152 is provided above the material inlet to prevent the material from jumping out of the action range of the first push rod 151, causing material waste.

[0040] In the embodiment, a plurality of push rod groups are arranged on the chain 150, and the first push rod 151 is arranged on the push rod group. The push rod group is composed of two push rod units, i.e., the first push rod unit 200 and the second push rod unit 300. The first push rod unit 200 and the second push rod unit 300 are each composed of two first push rods 151 and an intermediate connecting portion. The first push rod unit 200 and the second push rod unit 300 are assembled on the chain 150 in a cross manner. Meanwhile, the intervals of the first push rods 151 are equal. The first push rod unit 200 is provided with a protrusion 210 on each connecting portion, which is used to eliminate the activity between the chains 150 and ensure that the intervals of the first push rods 151 are equal after the assembly of each first push rod 151 is completed, so as to stabilize the feeding and discharging.

[0041] In the embodiment, the linear slide rail 160 is two. In other embodiments, according to the length of the base plate 110, the linear slide rail 160 can be of other numbers, such as 3, 4, etc.

[0042] In the embodiment, the U-shaped tray 170 is fixed by the support frame 180 fixed on the base plate 110. In other embodiments, other fixing methods can also be used. For example, the U-shaped tray 170 is slidably connected with the linear slide rail 160 through the combination of the pulley and the support rod, and slides together with the base plate 110.

[0043] In the embodiment, the support table 100 is provided below with a support structure 600 in the shape of a cuboid frame, and the lower end of the support structure 600 is provided with guide wheels near the four corners, respectively. A retractable fixed base is arranged beside each guide wheel.

[0044] In the embodiment, the tensioning device includes a tensioning slide rail 113, which is fixedly arranged below the second driven sprocket 140 on the upper surface of the base plate and connected with a driven sprocket plate. The second driven sprocket 140 is installed on the driven sprocket plate, and the driven sprocket plate can slide on the tensioning slide rail 113. The tensioning cylinder 111 drives the second driven sprocket 140 to the right end away from the tensioning cylinder 111 on the tensioning slide rail 113 through the jacking rod 112, so that the chain 150 remains in a tensioned state when the base plate 110 moves left and right, thereby avoiding chain disengagement.

[0045] The material pushing device 3 is used to push a specified number of materials out of the material collecting device 2 to the discharging conveyor 4. The specific structure includes a multi-claw push plate 31 and an inclined slide plate 32. The multi-claw push plate 31 is arranged at the end of the material collecting device 2 and is driven by a cylinder, which can simultaneously push a plurality of materials out of the material collecting device 2 to the inclined slide plate 32. The inclined slide plate 32 is inclined downward from the material collecting device 2 to the discharging conveyor 4.

[0046] In the embodiment, the multi-claw push plate 31 is a four-claw push plate, which can simultaneously push four materials out of the inclined slide plate 32. In other embodiments, push plates with other numbers of claws can also be used.

[0047] The discharge conveyor 4 connects the material pushing-out device 3 and the block packaging machine, and completes the final packaging and conveying of the material. The specific structure includes a discharge conveying belt 41 and a plurality of second push rods. The second push rods are equidistantly arranged on the surface of the discharge conveying belt 41, and the distance between the second push rods matches the packaging pitch, so that the material can be effectively prevented from falling off.

[0048] In the embodiment, a fixed support frame matching the shapes of the disc feeder 10, the second belt conveyor 14 and the discharge conveying belt 41 is arranged below the disc feeder 10.

[0049] In the embodiment, the material collection and conveying device is used to arrange the material, so that the subsequent block packaging machine can continue to package. The whole collection process includes a feeding stage, a material collection stage and a material pushing-out stage. The specific description is as follows.

[0050] 1. The feeding stage: the material is arranged into a single column on the disc feeder 10 by centrifugal force, and then the material is adjusted in distance by the speed difference of the first belt conveyor 13 and the second belt conveyor 14, and then the high-speed detection eye triggers the feeding signal.

[0051] 2. The material collection stage: the material enters the U-shaped tray 170, the chain 150 drives the push rod to move the material, and rotates clockwise along the running direction of the material on the second belt conveyor 14. When the discharge port needs to push out the material, the base plate 110 moves to the left, so as to offset the rotation amount of the chain 150, ensure that the material grid of the discharge port is stationary, and make the multi-claw push plate 31 smoothly push out the material; after the material is pushed out, the base plate 110 moves to the right to reset, so that the first push rod 151 on the left side with the material moves to the discharge port, and then the material continues to be pushed out. During this period, the material continues to enter the U-shaped tray 170 and is pushed by the first push rod 151, so as to realize the continuous operation of feeding and discharging.

[0052] 3. The material pushing-out stage: the multi-claw push plate 31 pushes a plurality of materials to the inclined slide plate 32, and then the materials are sent to the subsequent block packaging machine through the discharge conveying belt 41 to complete the final packaging.

[0053] In the embodiment, the first motor 400 driving the ball screw 190 needs to be accurately controlled by a program, so as to ensure that the horizontal movement amount of the base plate 110 can meet the continuous operation of feeding and discharging. For example, a plurality of servo motors can be used for linkage control. In addition, in other embodiments, other control methods can also be used.

[0054] In the embodiment, the feeding conveyor 1, the material collection device 2, the material pushing-out device 3 and the discharge conveyor 4 are connected to each other through quick-release bolts. In addition, in other embodiments, other standardized interfaces can also be used for connection.

[0055] In summary, the present embodiment realizes efficient collection and packaging of materials through automation design, reduces manual intervention, improves productivity by more than 3 times of the traditional way, and reduces safety hazards. The modular structure facilitates maintenance, and the chain 150 tensioning and limiting design ensures long-term stable operation of the equipment.
