The invention belongs to the field of carbon material product production equipment, and particularly relates to an isostatic pressing graphite small cylindrical carbon rod full-automatic production system which comprises an automatic weighing and feeding system which comprises a negative pressure temporary storage bin, a feeding machine, a rotary vibration screen, a measuring bin and an elephant trunk which are sequentially arranged from top to bottom, and the elephant trunk is fixed to a feeding trolley; the automatic forging and taking system comprises a die-casting die, a die-casting head, an ejection mechanism, a positioning sensor and a mechanical arm. During die-casting, the positioning sensor determines that the die-casting head corresponds to the feeding port of the die-casting die, after the die-casting head is started to conduct die-casting forming on carbon powder, the formed carbon rod is ejected out through the ejection mechanism, a material taking signal is sent to the mechanical arm, and the mechanical arm clamps the carbon rod through the clamp arranged at the end and transfers the carbon rod to the stacking position. The invention further provides a control method, the production system and the control method are easy to operate, safe and reliable, and obtained products are high in quality and precision.

The utility model discloses a carbon black muffle furnace with safety protection function, including muffle furnace body, the inside of muffle furnace body is provided with heating cavity, the lateral wall of heating cavity is provided with the chute, the inner wall sliding connection of chute has the movable block, one end fixed connection of movable block has the placing plate, and another end of movable block installs the mobile mechanism with placing plate cooperation. In the utility model, through setting the placing plate, chute and mobile mechanism, through the rotation handle, the movement of connecting block can be driven through screw rod, drives the unfolding or folding of scissor fork frame to move placing plate and movable block along the chute, can move out the inside of muffle furnace body outward, convenient to use, save time and effort, also can avoid the operator from inside and take the material, and the scalding accident occurs, and the operation is more safe, simultaneously, when along with the chute and move the crucible that is equipped with carbon black, can keep stable, guaranteeed the stability when the crucible moved out.

The invention relates to the technical field of plate shearing machines, in particular to a plate shearing machine safety protection device which comprises a plate shearing machine body, a protection mechanism is arranged on the outer wall of one side of the plate shearing machine body and comprises a U-shaped seat, the U-shaped seat is fixedly connected to the outer wall of the plate shearing machine body, and a guardrail is fixedly connected to the outer wall of the top of the U-shaped seat. The two ends of the guardrail are fixedly connected to the machine body, openings are formed in the outer walls of the two sides of the guardrail correspondingly, and a first protection assembly and a second protection assembly are arranged on the inner walls of the two openings correspondingly. The protection mechanism is arranged on the plate shearing machine body, and the U-shaped seat and the guardrail in the protection mechanism are matched, so that the blanking area of the plate shearing machine is conveniently protected and blocked, workers are prevented from taking materials in the blanking area when the plate shearing machine works, the safety performance of the plate shearing machine is improved, the safety accident rate of the plate shearing machine is reduced, and the safety of the plate shearing machine is improved. And the two protection assemblies are arranged on the guardrail, and the protection assemblies can be opened conveniently after the plate shearing machine completes discharging, so that workers enter the plate shearing machine to take materials.

The application provides a data paging query method and device, a database system, equipment and a medium. The data paging query method comprises the following steps: in response to a query request for a target data page from a client, obtaining vector data required to be included in the target data page from a data set cached by a server; the vector data included in the data set is vector data in a target query range obtained from a vector database by the server in response to a data query request from the client when the data query request is determined to be a paging query; and the vector data required to be included in the target data page is fed back to the client. The application can reduce the influence of the paging query scene on the performance of the vector database.

The invention discloses a question and answer retrieval method and device. The method comprises the steps that a question to be answered is received, a hotspot question and answer set at a target moment is obtained, question and answer combinations in the hotspot question and answer set are updated according to a preset updating frequency, and the preset updating frequency is dynamically changed based on the query per minute (QPM); under the condition that the question and answer combination matched with the to-be-answered question exists in the hotspot question and answer set, generating an answer of the to-be-answered question according to the matched question and answer combination; and under the condition that the question and answer combination matched with the to-be-answered question does not exist in the hotspot question and answer set, generating an answer to the to-be-answered question by adopting a preset language model or according to historical question and answer data. According to the method provided by the invention, the technical problem of relatively low retrieval efficiency caused by performing retrieval matching on a new problem and a full-amount historical problem in related technologies is at least solved.

The utility model discloses a kind of determination devices of total transmittance of transparent material, more specifically in the total transmittance determination technical field of transparent material, including determination support frame, the upper end of determination support frame is provided with transparent material transmittance determination processing device, the transparent material transmittance determination processing device includes: determination component and positioning test component, the positioning test component is arranged in the inside of determination support frame upper and lower two ends. The utility model through, when monitoring work is carried out to transparent material body, can be determined by the transmittance detection receiver and transparent material total transmittance tester body of upper and lower two ends setting, the device is completed transmittance determination work by setting positioning test component and determination component cooperation, realizes determination stable while, solves the problem of determination blanking, avoids the problem of taking material under the condition of direct light source measurement of staff, effectively enhances the practicability and use safety of entire device.

The embodiments of the present application provide a method, device, electronic device and storage medium for querying personnel information, and relate to the field of information query. The method comprises: receiving a first query request sent by a terminal, querying a knowledge graph according to a unique identifier of a person to be queried, determining an entity to be queried as a reference entity, and returning other entities directly associated with the reference entity as a first query result to the terminal, receiving a second query request sent by a terminal, and returning other entities directly associated with the entity to be queried using the knowledge graph according to the entity to be queried as a second query result to the terminal. The embodiments of the present application achieve fast and accurate retrieval of personnel information and other information associated with the person, reducing the time for retrieving information, avoiding more unnecessary retrieval processes, and saving resources at the same time.
