Description

Technical Field

[0001] The utility model belongs to the technical field of material sampling devices, in particular to an automatic material sampling device. Background Art

[0002] Sampling is a routine operation in the field of production and processing. For example, in the papermaking field, in order to ensure the quality of the paper produced, it is necessary to sample its raw materials to avoid the mixing of inferior materials in the materials, which will affect the quality of subsequent products.

[0003] At present, there are generally four sampling points for papermaking raw materials. After the materials are put into the material pit, they are transported to the belt conveyor by the chain plate. The chain plate and the belt conveyor are the first and second manual material collection points respectively. Then the belt conveyor is transported to the next belt conveyor until it reaches the drop point. The next belt conveyor and the drop point are the third and fourth manual material collection points.

[0004] The above-mentioned manual material collection points are all before and after the transfer point of the material transmission line, that is, after the material falls on the chain plate or belt, it is manually collected. The problem with collecting materials at the current manual material collection points is that: since the raw materials for papermaking include flaky materials such as bagasse, reeds, bark, wheat straw and bamboo, during processing, there will inevitably be impurities such as debris or dust in them. After each transfer and drop, due to vibration, fine impurities will be placed under the material. If manual collection only takes the upper layer of material, it will cause inaccurate sampling.

[0005] Moreover, manual sampling is not only labor-intensive but also involves human intervention in materials, which affects the reliability of sampling. Summary of the Invention

[0006] The purpose of the utility model is to provide an automatic material sampling device with scientific and reasonable structural design, reduced labor intensity, improved sampling efficiency, objectivity, strong reliability, high accuracy and easy implementation.

[0007] The utility model solves the technical problem by the following technical solutions:

DETAILED DESCRIPTION

[0026] The present invention will be further described in detail below through specific embodiments. The following embodiments are merely illustrative and non-restrictive, and should not be used to limit the scope of protection of the present invention.

[0027] The automatic material sampling device is installed at the transfer point of the material when in use. That is, in the process of falling from a higher place to a lower place, the falling material is sampled through the sampling container, and then poured into the packaging mechanism for packaging and packaging, and finally unloading.

[0028] Example 1,

[0029] The innovation of the automatic material sampling device lies in that it includes an installation base 6, a sampling mechanism 9 and a packaging mechanism. The packaging mechanism is installed on one side of the installation base, and a sampling mechanism with a drop point higher than the packaging mechanism is installed on the other side of the installation base; the sampling mechanism includes a six-axis robotic arm robot and a sampling container 1, and a sampling anti-smashing device 2 is driven and installed at the end of the robotic arm 3 of the six-axis robotic arm robot, and a sampling container is installed at the end of the sampling anti-smashing device.

[0030] In order to avoid the impact force of stones, sticks, chains, etc. in the incoming materials on the robotic arm and achieve the purpose of protecting the robotic arm, the utility model provides a sampling anti-smashing device between the robot and the sampling container, and the sampling anti-smashing device includes a sampling container mounting block 20, a flip block 21, a fixed block 22, a mounting frame 23, a sensor 24 and a spring 25. The fixed block is fixedly mounted at the end of the sampling robot through a flange 26, and the flange extends from the lower part of the fixed block. The flip block is hinged at the front end of the fixed block through a torsion spring, and the sampling container mounting block is fixed at the front end of the flip block. The sampling container connecting rod 19 is installed on the sampling container mounting block, and a sampling box is provided at the end of the connecting rod of the sampling container. A spring 25 is installed between the flip block and the protruding flange, and a mounting frame is installed above the flip block. The sensor arranged opposite to the fixed block is installed on the mounting frame.

[0031] During operation, when debris falls onto the sampling box or connecting rod of the sampling container, the sampling container will be flipped downward due to gravity. At this time, the sensor on the mounting frame will be driven to lift up. After the sensor senses the change in its relative position with the fixed block, it sends a signal to the control mechanism of the sampling device. The control mechanism stops the sampling device. After manual maintenance, that is, after removing the debris from the sampling container, the sampling container will return to its original position under the action of the spring and continue to work.

[0032] The packaging mechanism includes a guide channel 5 and a sealing machine 7. A vertical guide channel is installed on the side of the installation base. A receiving hopper 4 is provided at the upper end of the guide channel. A sealing machine is installed on the lower installation base of the guide channel.

[0033] The sealing machine is mainly composed of heating blocks arranged in a casing and driven by a motor to move relative to each other. The packaging bag passes between two heating blocks and is clamped by the two heating blocks to complete the sealing work.

[0034] During operation, the sampling container completes the material collection and sampling on the side of the blanking material, and then the six-axis robotic arm rotates 180° horizontally to the top of the receiving hopper, and drives the sampling container to rotate 180° vertically, so that the material falls from the sampling container into the receiving hopper, and the material falls along the guide channel into the packaging bag pre-placed at the bottom. Under the action of gravity, the packaging bag containing the material passes through the middle of the sealing machine and completes the sealing operation.

[0035] Example 2,

[0036] In order to facilitate monitoring the weight of the sampled material, the present invention further includes a weighing mechanism 8, which is mounted on the bottom of the packaging mechanism on the mounting base. The weighing mechanism comprises a weighing pan assembly 15 and a flip seat disposed at the bottom of the weighing pan assembly. The flip seat comprises a rotary cylinder 11, a seat frame 17, a coupling 12, a bearing seat 13, a connecting shaft 14, and a weighing pan bracket 16. The seat frame is fixed to the mounting base, and connecting shafts are mounted on the left and right walls of the seat frame via bearing seats. The weighing pan bracket is mounted on the two connecting shafts. One side of the connecting shaft is connected to the cylinder rod of the rotary cylinder via a coupling, and the weighing pan assembly is mounted on the weighing pan bracket. The weighing pan assembly is a structure in which a weighing sensor is disposed at the bottom of the weighing pan.

[0037] When the material dropped onto the weighing pan meets the preset weight requirement, the rotating cylinder drives the weighing pan bracket to flip over, completing the weighing and unloading of the material on the weighing pan.

[0038] Example 3,

[0039] In order to solve the problem that the sampling point is lower than the packaging discharge port and the distance between the two is far, the present invention also designs another form of sampling robot, which includes a robotic arm, a sampling anti-smashing device and a transfer and lifting mechanism 10. The sampling anti-smashing device is driven and installed at the end of the robotic arm, and a sampling container is installed at the end of the sampling anti-smashing device. The robotic arm is lifted and installed on the transfer and lifting mechanism; the transfer and lifting mechanism includes a rotating table 18 and a lifting truss. A rotating table is installed on the rotating table, and a lifting truss is installed on the rotating table. The robotic arm is lifted and installed on the rotating truss through the cooperation of a gear and a rack. During operation, the robotic arm is transported and lifted to the position of the receiving hopper through the cooperation of the rotating table and the lifting truss, and then the material is poured into the receiving hopper.

[0040] The utility model can replace manual sampling to achieve automatic sampling without human intervention. The sampling operation can be set at the transfer point of each material, which can not only ensure the completeness of sampling, but also eliminate the subjective uncertainty error of manual sampling, so as to achieve objective and fair sampling, and at the same time achieve the purpose of reducing costs and increasing efficiency for enterprises.

[0041] Although the embodiments and drawings of the present invention are disclosed for illustrative purposes, those skilled in the art will understand that various replacements, changes and modifications are possible without departing from the spirit and scope of the present invention and the appended claims. Therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
