Description

Technical Field

[0001] This application relates to the field of tobacco sampling technology, and specifically to a sampling device for a finished tobacco processing cabinet. Background Technology

[0002] In response to situations such as machine shutdowns and material shortages in the tobacco processing workshop, large fluctuations in processing parameters and quality indicators, and batches of process tests, it is necessary to take samples of more than 300g of each batch of finished tobacco of that brand in the tobacco storage cabinet for manual sampling and evaluation. Only after the finished tobacco passes the evaluation can it be sent to the packaging workshop for use. If the evaluation determines that it is abnormal, the quality early warning control and corrective action control procedures should be initiated in a timely manner; if the evaluation determines that it is a non-conforming product, the non-conforming product control and disposal procedures should be initiated in a timely manner.

[0003] When taking tobacco from the finished tobacco storage cabinet, samples should be taken from at least three different locations, 10-15 cm below the surface, avoiding edges and corners. Currently, manual entry into the storage cabinet is mainly used for sampling. This sampling method involves stepping on the tobacco, damaging its appearance, and the sampling points are concentrated at the head of the storage cabinet, resulting in insufficient representativeness. Utility Model Content

[0004] This application provides a sampling device for finished tobacco storage cabinets, which aims to solve the problem of damage to tobacco shreds during manual sampling of tobacco shreds in tobacco storage cabinets.

[0005] In one embodiment, a finished silk cabinet sampling device is provided for mounting on a trolley body, comprising:

[0006] Telescopic cylinder, push-pull cylinder, connecting platform, movable base, tie rod, gripper and base connecting block;

[0007] The telescopic cylinder is installed on the reciprocating moving device on the top of the wire storage cabinet. A connecting platform is installed on the telescopic rod of the telescopic cylinder. The main body of the push-pull cylinder is installed on the connecting platform, and the telescopic rod of the push-pull cylinder passes through the connecting platform downwards.

[0008] The movable base is installed on the top of the telescopic rod of the push-pull cylinder. The gripper is hinged to the movable base through the base connecting block. There are three or more grippers hinged on the movable base. The upper end of the pull rod is rotatably connected to the outside of the connecting platform, and the lower end of the pull rod is rotatably connected to the middle of the gripper. The opening and closing of the gripper is achieved by the up and down movement of the movable base in conjunction with the pull rod.

[0009] In one design, hinge seats are installed on the outer side of the connecting platform, with the number of hinge seats corresponding one-to-one with the number of grippers; gripper connecting blocks are installed on the outer side of the upper part of the grippers; and the two ends of the pull rod are respectively hinged to the hinge seats and the gripper connecting blocks.

[0010] In one design, the connecting platform is a ring-shaped structure, and a bracket is installed inside the connecting platform for mounting push-pull cylinders.

[0011] In one design, solenoid valves are installed on the air pipes of the telescopic cylinder and the push-pull cylinder, respectively, and the solenoid valves control the opening and closing of the air path of the telescopic cylinder or the push-pull cylinder.

[0012] In one design, the lower end of the lever has a "U"-shaped bayonet with a through hole for easy hinge connection with the gripper.

[0013] The beneficial effects of this application are:

[0014] The opening and closing of the gripper is controlled by a push-pull cylinder, a movable base, and a pull rod. In conjunction with a telescopic cylinder, the gripper is sent into the tobacco pile in the tobacco storage cabinet. The gripper is then opened and closed again by the push-pull cylinder, the movable base, and the pull rod to grab sample tobacco. With the addition of a reciprocating moving device, multi-point tobacco sampling can be achieved, improving the representativeness of the samples, while avoiding quality inspectors from entering the tobacco storage cabinet to take samples and causing damage to the tobacco.

[0026] This application proposes improvements and innovations, and presents the following embodiments.

[0027] In some implementations, please refer to Figures 1 to 2 A finished yarn cabinet sampling device is provided, which is installed on a reciprocating moving device on the top of the yarn storage cabinet, comprising:

[0028] Telescopic cylinder 1, push-pull cylinder 2, connecting platform 3, movable base 4, pull rod 5, gripper 6, bracket 7, hinge seat 8, base connecting block 9 and gripper connecting block 10;

[0029] Telescopic cylinder 1 is bolted to the reciprocating moving device on the top of the wire storage cabinet, and the reciprocating moving device drives telescopic cylinder 1 to move inside the wire storage cabinet.

[0030] A screw is welded to the telescopic rod of the telescopic cylinder 1, and the telescopic cylinder 1 is connected to the nut welded to the connecting platform 3 through the screw. The connecting platform 3 is a ring-shaped structure, and a bracket 7 is installed inside the connecting platform 3. The main body of the push-pull cylinder 2 is installed on the bracket 7, and the telescopic rod of the push-pull cylinder 2 passes through the bracket 7 downward.

[0031] The movable base 4 is detachably mounted on the top of the telescopic rod of the push-pull cylinder 2. The grippers 6 are hinged to the movable base 4 via the base connecting block 9. Three grippers 6 are mounted on the movable base 4. Three hinge seats 8 are mounted on the outer side of the connecting platform 3. The upper end of the pull rod 5 is rotatably connected to the hinge seats 8 on the outer side of the connecting platform 3. The lower end of the pull rod 5 has a "U"-shaped bayonet with a through hole. A gripper connecting block 10 is mounted on the outer side of the middle part of the gripper 6. The lower end of the pull rod 5 is rotatably connected to the gripper connecting block 10 in the middle part of the gripper 6 via the "U"-shaped bayonet. In use, the grippers 6 open and close by moving the movable base 4 up and down in conjunction with the pull rod 5.

[0032] Two-position five-way solenoid valves are installed on the air pipes of telescopic cylinder 1 and push-pull cylinder 2 respectively. The extension and retraction of telescopic cylinder 1 or push-pull cylinder 2 are achieved by switching the airflow direction through the two-position five-way solenoid valves.

[0033] When sampling is required, the reciprocating moving device on the top of the wire storage cabinet moves the finished wire cabinet sampling device above the sampling position. The solenoid valve of the push-pull cylinder 2 retracts the compressed gas, the telescopic rod of the push-pull cylinder 2 retracts, the movable base 4 rises, the gripper 6 closes, and the solenoid valve of the push-pull cylinder 2 cuts off the compressed gas.

[0034] When the working end of the solenoid valve of the telescopic cylinder 1 is connected to the compressed gas, the telescopic cylinder 1 extends and pushes the gripper 6 into the tobacco pile. Then, the working end of the solenoid valve of the push-pull cylinder 2 is connected to the compressed gas, the telescopic rod of the push-pull cylinder 2 is pushed out, the movable base 4 is lowered, and the gripper 6 is opened. The solenoid valve of the push-pull cylinder 2 cuts off the compressed gas. At the same time, the telescopic cylinder 1 continues to push the gripper 6 down a certain distance.

[0035] When the solenoid valve of the push-pull cylinder 2 returns to the retracting end, it connects to the compressed gas. The push-pull cylinder 2 retracts, causing the gripper 6 to close and grasp the sampled tobacco. Then, the solenoid valve of the push-pull cylinder 2 cuts off the compressed gas.

[0036] When the return end of the telescopic cylinder 1 is connected to compressed gas, the telescopic rod of the telescopic cylinder 1 retracts, pulling the gripper 6 and the sampled tobacco shreds to rise as a whole, exiting the tobacco shred pile in the tobacco storage cabinet. Then, the solenoid valve of the telescopic cylinder 1 cuts off the compressed gas, controls the reciprocating moving device to move the finished tobacco shred cabinet sampling device to the sampling window, and opens the gripper 6.

[0037] The above are merely optional embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of this utility model.
