Description

Technical Field

[0001] The utility model relates to the technical field of automated production diversion transmission, in particular to a silkworm cocoon dropping device. Background Art

[0002] The cocoon power device and the transport device are part of the cocoon cutting machine. The cocoon cutting machine generally also includes a clamping device, a cutting device and a separation device. During the working process of the cocoon cutting machine, the cocoon power device and the transport device work closely together to provide necessary material support for the subsequent cutting work. The transport device is located behind the power device, and its main function is to divide the cocoons in the feed box into single or multiple cocoons, and carry out subsequent cutting work in batches. During the operation of the transport device, it uses different transportation methods to sequentially transport the separated cocoons to the workbench of the cutting device.

[0003] The cocoon transport device needs to be finely adjusted and controlled so that the cocoons can be transported back one by one without stacking for cutting (cutting part of the cocoon shell to separate the cicada pupae inside). This requires the cocoons to fall into the transport device one by one and intermittently, thereby realizing the automatic reciprocating transport of the cocoons.

[0004] This case was created to solve the above problems. Utility Model Content

[0014] (III) Beneficial effects

[0015] After adopting the above technical solution, the utility model has the following advantages compared with the prior art:

[0016] 1. The present invention discloses a silk cocoon diversion and dropping device, which utilizes a conveyor belt diversion design to realize automatic diversion of silk cocoons. The silk cocoons are orderly divided into four channels through the diversion channel, and the silk cocoons can be dropped into the transport device one by one and intermittently, so that the silk cocoons can be automatically transported backwards one by one for cutting operations without stacking, which greatly improves the overall degree of automation. That is, the present solution is not a simple diversion, but can still automatically drop materials one by one and regularly after diversion.

[0017] 2. The cocoon diversion and dropping device of the present invention can realize continuous and efficient cocoon diversion and can process a large number of cocoons. This automated diversion process can save human resources and reduce the impact of human factors on product quality. Compared with traditional manual sorting, the cocoon diversion slide device has a faster processing speed and can improve production efficiency.

[0018] 3. The present invention provides a cocoon diversion and dropping device, in which cocoons of the same size are dropped in an orderly manner on a track. The orderly dropping can effectively reduce the degree of disorder of the cocoons on the production line, and can better control the landing position and method of the cocoons, so as to perform screening, sorting or further clamping, cutting and other processing according to their landing position or other characteristics.

[0019] 4. The present invention provides a cocoon diversion and dropping device, which can realize automatic control and management. The sensor monitors the position and state of the cocoons in real time, and the control system performs precise regulation based on the sensor feedback, so that the cocoons fall in an orderly manner, and the rotation of the conveyor belt is stopped when the cocoons are piled up. This device not only improves production efficiency and reduces manual intervention, but also ensures the quality of the cocoons and the stability of the products. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The utility model is further described in detail below through the drawings and embodiments.

[0029] like Figure 1-3 As shown: a cocoon dropping device, including a frame 1 and an acrylic tube 5. In order to understand the device more intuitively, an acrylic tube 5 is not placed with an acrylic tube support block 6. The acrylic tube 5 is installed on the right side of the frame 1, and each acrylic tube 5 is fixed by two acrylic tube support blocks 6. The acrylic support blocks 6 are fixed to the frame 1 by screws, and the acrylic support blocks 6 can adjust the tightness of the acrylic tube 5.

[0030] The frame 1 is equipped with a conveyor diversion mechanism, which includes a conveyor belt 2, a DC motor 13, and a diversion channel 4. The conveyor belt 2 is installed on the frame 1 through a conveyor belt support seat 3. There are 6 conveyor belt support seats 3, and the conveyor belt 2 is fixed to the frame 1 by screws. The DC motor 13 is installed on the left side of the conveyor belt 2, and the connection between the DC motor 13 and the conveyor belt 2 is installed in the housing to prevent dust from affecting the transmission effect.

[0031] The shunt channel 4 is installed on the right side of the frame 1. There are four shunt channels 4 (adapted to the subsequent cocoon clamping structure). A gap is left between the shunt channel 4 and the conveyor belt 2 to prevent the shunt channel 4 from rubbing the conveyor belt 2 and affecting the service life of the conveyor belt 2. The frame 1 is equipped with a cocoon drop detection sensor 7 and a cocoon full warehouse detection sensor 14, and a cocoon blocking mechanism is installed in the frame 1.

[0032] like Figure 4 and Figure 5 As shown, in the initial state, cylinder 2 9 extends and cylinder 1 8 retracts. The acrylic tube 5 has two holes in its wall, which are used to block the extension and retraction of the slide bar 10 and the slide bar 2 11. When all four cocoon drop detection sensors 7 detect that there are cocoons 16 in the acrylic tube 5, a high level is output to the PLC control system, and cylinder 1 8 and cylinder 2 9 act simultaneously. When cylinder 1 8 retracts, cylinder 2 9 extends. At this time, the bottom cocoon 16 falls, and the blocking slide bar 10 blocks the upper cocoon 16 to prevent it from falling. After the cocoon 16 falls, it is in Figure 5 The cocoon drop detection sensor 7 detects that there is no cocoon 16 in the acrylic tube 5, the cylinder 1 8 retracts, the cylinder 2 9 extends (that is, the blocking slide bar 2 11 extends), and the upper cocoon 16 falls to Figure 4 state, and then repeat this step to achieve the orderly falling of the cocoons 16 one by one.

[0033] When any one of the cocoon full warehouse detection sensors 14 detects the signal of the cocoons 16 for three seconds, it means that the cocoons 16 in the acrylic tube 5 are full, and the PLC control system controls the DC motor 13 to stop, thereby stopping the conveyor belt 2. After the cocoons 16 in the acrylic tube 5 fall off and the cocoon full warehouse detection sensor 14 can no longer detect the signal of the cocoons 16, the conveyor belt 2 continues to run, which can effectively prevent the accumulation of cocoons 16 and improve work efficiency.

[0034] like Figure 6 As shown, the cylinder 1 8 and the cylinder 2 9 are respectively mounted on the cylinder support seat 12. At the same time, the blocking slide bar 10 and the blocking slide bar 2 11 are fixedly connected to the cylinder 1 8 and the cylinder 2 9 by screws. The coordinated action between the two cylinders can be realized, so that the cylinder can achieve a larger stroke and operating range, and the flexibility and control accuracy of the system are improved.

[0035] like Figure 7As shown, the frame 1 is provided with four sensor openings for placing detection sensors 7 for detecting cocoons 16 when cocoons fall. The four cocoon falling detection sensors 7 are fixed on a sensor support block. The sensor support block 15 is provided with threaded holes for fixing on the frame 1. The four cocoon full warehouse detection sensors 14 are directly fixed on top of the frame 1.

[0036] The above-mentioned embodiments are for inspiration. Through the above-mentioned description, relevant staff can make various changes and modifications without departing from the scope of the invention. The technical scope of this new type of use is not limited to the content in the specification, and its protection scope must be determined according to the scope of the claims.
