Description

Technical Field

[0001] The present invention relates to the technical field of equipment for coal sample detection, and in particular to a coal sample packaging device. Background Art

[0002] Carbon and hydrogen are the main components of coal organic matter, and together with oxygen, they account for more than 95% of coal organic matter; and nitrogen is the only element in coal that exists completely in organic form. Therefore, understanding the carbon, hydrogen and nitrogen content in coal is of great significance for understanding the properties of coal, checking the test results of other indicators, and estimating indicators such as heat, materials, and pollutant emissions during the coal application process.

[0003] The methods for detecting carbon, hydrogen and nitrogen elements in coal in the prior art are based on a variety of detection instruments. These detection instruments can only automatically complete the detection process after the sample to be tested enters the detection instrument. Manual operations are still required for processes such as weighing the sample to be tested, preparing the sample with tin foil, and placing the sample to be tested in the designated position of the detection instrument.

[0004] The detection of carbon, hydrogen and nitrogen in coal requires the coal sample carrier of the carbon, hydrogen and nitrogen analyzer, that is, tin foil, to be compressed and exhausted. Coal sample packaging is mostly done manually, and in order not to affect the test results, it cannot be operated directly by hand. It is necessary to wear gloves or use simple tools to operate.

[0005] For the packaging of coal samples, firstly, a quantitative amount of coal samples is placed into a sample cup on a weighing device in a relatively closed space, and the coal samples are accurately weighed (the weight of coal samples is generally 60 mg ± 0.03 mg, or 80 mg ± 0.03 mg). Then, the sample cup containing the coal samples is taken out from the relatively closed space, and the sample cup is kneaded manually to form a ball. The purpose of repeated manual kneading is to completely expel the air in the sample cup to avoid the influence of the trapped gas on the test results. However, this method of packaging coal samples by manually kneading into a ball is very random, and it is easy for the coal samples to leak out due to loose sealing; and in order to make the sample cup seal tightly and remove the internal air through repeated kneading, it is easy for the sample cup to break during the kneading process, resulting in leakage of coal samples, which in turn leads to inaccurate results of coal sample element detection. Summary of the invention

[0006] The present invention provides a coal sample packaging device to solve the technical problems that the existing manual kneading and packaging of coal samples is highly random, the kneading and exhaust are not thorough, and the coal samples are easily leaked during the kneading process and the packaging is broken, resulting in the leakage of the coal samples.

The coal sample packaging equipment of the present invention links the sample cup manufacturing device, the material loading device, the sample cup sealing device and the sample packaging device 900 together through the side mold conveying mechanism 400 to form a coal sample packaging production line; in the coal sample packaging production line, the side mold conveying mechanism 400 carries the side wall mold 100, and the side wall mold 100 serves as both a molding mold for pressing and molding the sample cup and a transportation carrier for running the sample cup. At the cup making station, the sample cup manufacturing device presses the cup material on the side wall mold 100 to form a sample cup with an upper opening, and then transports it to the material loading station via the side mold conveying mechanism 400; at the material loading station, a quantitative coal sample is added into the sample cup from the upper opening of the sample cup by the material loading device, and transported to the sealing station via the side mold conveying mechanism 400; at the sealing station, the sample cup opening is sealed by the sample cup sealing device in a clamping manner, and the sealed sample cup is transferred to the packaging station for packaging via the sample packaging device 900, specifically, the sealed sample cup is squeezed into a ball by an up and down squeezing method in a pipeline and the internal gas is fully exhausted, and then the sample ball is output and collected for the convenience of sample ball detection. The material used for packaging can be tin foil of preset shape and size, or other metal foil commonly used for coal sample testing. No preliminary treatment of the metal foil is required, and a flat foil is sufficient. The entire packaging process is carried out in an orderly manner in a mechanized manner, wherein cup making, coal sample feeding, and sealing are all carried out on the side wall mold 100, and the sealed sample cup is pressed into a ball in a two-way pressing manner in the pipeline, which makes it less likely for the metal foil to break, the exhaust to be insufficient, or the coal sample to leak out, and finally a standard and unified coal sample ball sample is obtained. The coal sample packaging equipment also includes a control system, which is electrically connected to the side mold conveying mechanism 400, the sample cup manufacturing device, the material feeding device, the sample cup sealing device, and the sample packaging device 900, respectively, to achieve coordinated control.

[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the side mold conveying mechanism 400 includes a transfer platform 401 for carrying the side wall mold 100 and carrying the side wall mold 100 for moving and conveying, a bearing positioning hole groove 403 opened on the transfer platform 401 for the side wall mold 100 to pass through and position the side wall mold 100, a stepping drive device 402 for driving the transfer platform 401 to move step by step, and a lifting drive device 404 for driving the transfer platform 401 to rise and fall to realize switching between a conveying mode and a station operation mode; a plurality of bearing positioning hole grooves 403 are arranged at equal intervals on the transfer platform 401 along the conveying direction, and the spacing between two adjacent bearing positioning hole grooves 403 matches the stepping distance of the stepping drive device 402; the distance between the cup making station, the material loading station and the sealing station is an integer multiple of the spacing between two adjacent bearing positioning hole grooves 403. More specifically, the side mold conveying mechanism 400 is driven by the lifting drive device 404 and lowered to the lowest conveying position for conveying, and the side wall mold 100 is conveyed to the cup making station in a step-by-step manner, and then driven by the lifting drive device 404 and lowered to the highest working position for cup making; after the cup making is completed, the lifting drive device 404 is driven and lowered to the lowest conveying position for conveying, and the side wall mold 100 is conveyed to the material loading station in a step-by-step manner, and then driven by the lifting drive device 404 and lowered to the highest working position for cup making. The side mold conveying mechanism 400 also includes a conveying lifting detection magnetic switch 405 for detecting whether the lifting drive device 404 is in motion and moves to the detection position, and the conveying lifting detection magnetic switch 405 is electrically connected to the control system. The transfer platform 401 adopts a ring structure, and the step-by-step rotation of the transfer platform 401 is to circulate between the cup making station, the material loading station (when there is a waste material adding station, it also includes the waste material adding station) and the sealing station, and can maintain continuous operation.Optionally, when the stepping drive device 402 is required to operate to step and rotate the side wall mold 100, the lifting drive device 404 drives the transfer platform 401 and the stepping drive device 402 to move downward to the lowest position to avoid the cup making station, the material loading station (when there is a waste material adding station, it also includes the waste material adding station), the sealing station and the packaging station, as well as the upper pressure mold group 300, the material conveying mechanism 500, the sealing mechanism 800, the sample packaging device 900 (when there is a waste material adding station) at the high position of each station. , and also includes a waste sample adding mechanism 1000), etc.; when the stepping drive device 402 needs to be stopped to perform at least one of the operations of cup making, coal sample loading (when there is a waste adding station, it also includes waste unloading), sealing, packaging, etc., the lifting drive device 404 drives the transfer platform 401 and the stepping drive device 402 to the highest position to approach the upper support 601, thereby facilitating at least one of the operations of cup making, coal sample loading (when there is a waste adding station, it also includes waste unloading), sealing, packaging, etc. Optionally, the side mold conveying mechanism 400 can also adopt a linear transmission, and pass through the cup making station, the material loading station (when there is a waste adding station, it also includes the waste adding station) and the sealing station in sequence. Optionally, the side mold conveying mechanism 400 can also adopt a linear transmission, and pass through the cup making station, the material loading station (when there is a waste adding station, it also includes the waste adding station) and the sealing station in sequence.

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, the side wall mold 100 includes a conical mold shell 101 having a variable diameter inner cavity that is larger at the top and smaller at the bottom, and a material receiving ring 102 that is located on the upper end surface of the conical mold shell 101 and extends radially outward. The conical mold shell 101 adopts a variable diameter inner cavity that is larger at the top and smaller at the bottom. The cup-making pressing force applied when the conical mold shell 101 is used to make a cup is adapted to the shape of the inner cavity and realizes the gradual deformation of the cup-making material, ensuring that the cup-making material is not easy to break during the cup-making process; and the sample cup in the conical mold shell 101 will produce a gradual compression force deformation when subjected to a downward pressure from top to bottom, and will easily break away from the conical mold shell 101 when subjected to a downward force from bottom to top. Optionally, the cone mold shell 101 is designed as a cone shape with a larger top and a smaller bottom, or the inner cavity of the cone mold shell 101 is designed as a cone inner cavity with a larger top and a smaller bottom; this is to facilitate the pressing of the material receiving ring 102 into the inner cavity of the cone mold shell 101, and to avoid sharp angle contact during the pressing process to avoid shear damage. Optionally, the corner of the upper opening of the cone mold shell 101 is set as an arc transition corner, so that when the cup material is pressed, it can not only guide the cup material during pressing, but also avoid stress concentration damage and shear damage to the cup material during pressing; at the same time, when sealing the sample cup and outputting the sealed sample cup, it is also convenient to pass through the upper opening and / or lower opening of the cone mold shell 101 to operate the sample cup. Optionally, the cone mold shell 101 is set as a cone inner cavity, so that the side wall of the molding cavity is also cone-shaped, and the sample cup formed by pressing is also a cone sample cup, which is convenient for the coal sample to enter the cup. At the same time, compared with the uneven side wall of the existing boat-shaped sample cup, the conical side wall with the same height is also convenient for sealing and packaging the coal sample. Optionally, the cone mold shell 101 adopts a cone inner cavity. Optionally, the cone angle of the inner cavity of the cone is 10° to 90°, which can facilitate cup making, achieve stable loading and transportation of the sample cup, facilitate the grabbing and transfer of the side wall mold 100, and facilitate the gradual compression and output of the sealed sample cup. When sealing, the deformation of the sample cup is moderate and the coal sample is not easy to leak out; too small a cone angle, the cone angle is less than 10°, causes the inner wall surface of the cone mold shell 101 to be almost vertical, which is not conducive to the pressing and molding of the sample cup, and is also not conducive to the stable loading of the sample cup; too large a cone angle, the cone angle is greater than 90°, makes the opening size of the sample cup too large, which is not conducive to sealing, and the coal sample is easy to leak out due to the excessive deformation of the sample cup when sealing.

[0042] like Figure 1 , Figure 3 , Figure 6 and Figure 7As shown, in this embodiment, the sample cup sealing device includes a sealing lifting mechanism 700 arranged at the sealing station for lifting the sample cup in the side wall mold 100 to a preset height, and a sealing mechanism 800 for sealing the sample cup lifted by the lifting mechanism; the sealing mechanism 800 and the sealing lifting mechanism 700 are arranged opposite to each other in upper and lower directions, and the side mold conveying mechanism 400 is located between the sealing mechanism 800 and the sealing lifting mechanism 700. The coal sample is quantitatively added into the sample cup and is located in the variable diameter inner cavity of the side wall mold 100, and the sample cup is supported by the variable cross-section inner wall of the side wall mold 100; the side wall mold 100 is transported to the sealing station by the side mold conveying mechanism 400, and the sealing lifting mechanism 700 extends vertically from below into the lower opening of the side wall mold 100 for lifting movement, so as to lift the sample cup in the side wall mold 100 at the sealing station to a predetermined height, and then the upper part of the sample cup is extended out of the upper opening of the side wall mold 100, and then the sealing mechanism 800 performs a clamp-type sealing action on the sample cup extending out of the upper opening of the side wall mold 100, thereby completing the sealing of the sample cup, and the sealed sample cup is released by the sealing mechanism 800 and descends along with the sealing lifting mechanism 700 and falls back into the variable diameter inner cavity of the side wall mold 100. The sealing process of the sample cup is carried out in sequence and in an orderly manner, that is, the conveying, lifting and sealing are carried out in an orderly manner, so that each sample cup is sealed with a unified standard, the sealing position and the sealing force are unified, so the product standard after sealing is unified, and it is not easy to have defective products, sample leakage, etc.; and each sample cup is sealed in sequence by mechanization and unified standards, the quality of the sealing can be guaranteed, the sealing position is not easy to leak the sample, and the sealing part of the sample cup is not easy to be damaged. Optionally, the control system is electrically connected to the side mold conveying mechanism 400, the sealing lifting mechanism 700, and the sealing mechanism 800 respectively, so as to realize the coordinated work control of the side mold conveying mechanism 400, the sealing lifting mechanism 700, and the sealing mechanism 800. Optionally, the sample cup sealing device includes a side wall mold 100, a side mold conveying mechanism 400, a sealing lifting mechanism 700 and a sealing mechanism 800. The side wall mold 100 can be flexibly selected according to the shape and style requirements of the sample cup; specifically, side wall molds 100 with different inner cavity sizes and different inner cavity shapes can be selected, and then sample cups of different shapes and sizes can be carried in the inner cavity of the side wall mold 100 to meet the needs of different sample packaging. For example, the inner cavity of the side wall mold 100 adopts a conical inner cavity, a polygonal conical inner cavity, a multi-step inner cavity, etc.

[0043] like Figure 1 , Figure 3 and Figure 6As shown, in this embodiment, the sealing mechanism 800 includes a sealing lifting cylinder 801, a sealing cylinder 802 arranged at the movable end of the sealing lifting cylinder 801, and a sealer 803 arranged at the movable end of the sealing cylinder 802. The sealing lifting cylinder 801 is used to realize the lifting and lowering control of the sealer 803. When the side mold conveying mechanism 400 is running and conveying the side wall mold 100 and the sample cup in the side wall mold 100, the sealing lifting cylinder 801 drives the sealer 803 to rise to avoid the operation of the side mold conveying mechanism 400; when the side mold conveying mechanism 400 conveys a group of side wall molds 100 and sample cups to stay at the sealing station, the sealing lifting cylinder 801 drives the sealer 803 to descend, so as to facilitate the sealing operation of the sample cup. When the sample cup needs to be sealed, the sealing cylinder 802 drives the sealer 803 to move to achieve the sealing of the sample cup. Optionally, the sealing lifting cylinder 801 can also replace other lifting mechanisms, such as existing lifting mechanisms such as a scissor lift, a lifting cylinder, and a lifting motor. Optionally, the sealing cylinder 802 can use existing claw devices such as parallel claws, swing claws, and rotating claws. Optionally, the sealing cylinder 802 can use a drive mechanism that can achieve parallel synchronous opening and closing, such as an existing drive or transmission method such as a synchronous belt mechanism and a synchronous gear mechanism.

[0044] like Figure 1 , Figure 3 and Figure 6As shown, in this embodiment, the sealer 803 includes two sealing units arranged in a relative manner, and the sealing unit includes a sealing base 8031 ​​fixed on the movable end of the sealing cylinder 802 and a sealing plate 8032 arranged on the sealing base 8031 ​​and arranged horizontally; the sealing plate 8032 has a V-shaped opening 8033, and the sealing plates 8032 of the two sealing units arranged in a relative manner are arranged in a vertically displaced manner, and the V-shaped openings 8033 of the sealing plates 8032 are arranged in a relative manner to enclose a rhombus-shaped cavity. The sealing plates 8032 of the sealing units arranged in a relative manner move relative to each other and are displaced and plugged in with each other to enclose a rhombus-shaped cavity, and then the sample cup extending upward is accommodated by the rhombus-shaped cavity. At this time, the sealing plates 8032 are further moved relative to each other in a relatively displaced plug-in manner, so that the rhombus-shaped cavity is gradually reduced and the protruding sample cup is gradually constrained, thereby achieving the sealing of the sample cup. Optionally, a protective layer is attached to the V-shaped opening 8033 to prevent stress concentration damage or shear force damage to the sample cup sealing position when the V-shaped opening 8033 moves relative to each other, so as to ensure the quality of the product sealing. Optionally, the protective layer on the V-shaped opening 8033 can be a rubber layer, a plastic layer, a fluff layer, etc. Optionally, the straight edge of the inner wall of the V-shaped opening 8033 can also be set as an arc edge, and the inner angle can also be set as an arc angle; so that the V-shaped opening 8033 that moves relative to each other encloses an elliptical cavity, a quasi-elliptical cavity, a circular cavity, and a quasi-circular cavity, so that the V-shaped opening 8033 avoids shear force damage to the sample cup sealing position when shrinking the hoop sample cup sealing position, so as to ensure the quality of the sealed product. Optionally, the inner wall corners of the V-shaped opening 8033 are all set as arc chamfers to avoid concentrated stress damage to the sample cup and ensure the quality of the sealed product.

[0045] like Figure 1 , Figure 3 and Figure 6As shown, in this embodiment, a plurality of sealing plates 8032 are arranged on each sealing base 8031, and the plurality of sealing plates 8032 are arranged at intervals in the vertical direction, and the interval distance is greater than or equal to the thickness of the sealing plate 8032. The plurality of sealing plates 8032 are relatively moved to hold the sealing position of the sample cup, so that the ring line compaction seal is changed into an annular surface seal, the seal is tight, and the problem of coal sample leakage is not easy to occur. Optionally, the shapes of the plurality of sealing plates 8032 can be consistent or different. Optionally, the outer side walls of the plurality of sealing plates 8032 are provided with avoidance grooves for forming avoidance space for surrounding components. Optionally, guide grooves, guide strips or guide rails for guiding each other's movement are also provided between the relatively arranged sealing plates 8032 to ensure the consistency of the direction of relative movement and not easy to deflect. Optionally, a limit member is provided between the relatively arranged sealing plates 8032 to prevent them from being completely separated from each other, so that the relatively arranged sealing plates 8032 are always in a partially overlapping state, and the relative closing action of the V-shaped opening 8033 and the mutual opening action of the V-shaped openings 8033 are realized in the partially overlapping state, thereby avoiding relative deviation caused by the complete separation of the sealing plates 8032 and abutment obstruction to the mutual movement.

[0046] like Figure 1 , Figure 3 and Figure 6 As shown, in this embodiment, the size of the V-shaped openings 8033 of the multiple sealing plates 8032 on the sealing base 8031 ​​gradually increases from top to bottom. The radial size of the clamping constraint space enclosed by the V-shaped openings 8033 of the relatively arranged sealing plates 8032 also increases from top to bottom. Since the sample cup is placed in the side wall mold 100 with its upper opening, and a coal sample is added to the sample cup, when the sample cup is pushed upward to the outside of the upper opening of the side wall mold 100 by the sealing lifting mechanism 700, the coal sample may exist in the protruding part of the sample cup. The structural layout in which the size of the V-shaped opening 8033 gradually increases from top to bottom, and the radial size of the clamp constraint cavity generated by the V-shaped opening 8033 also gradually increases from top to bottom, so that the sealing position of the sample cup constrained by the clamp forms a water drop shape (or a cone shape), which can effectively avoid direct rigid extrusion of the coal sample at the sealing position, and can also prevent the coal sample from being squeezed out of the cup mouth of the sample cup during the sealing process, and at the same time can achieve the purpose of tight sealing, thereby ensuring the quality of the product after sealing.

[0047] like Figure 1 , Figure 3 and Figure 7As shown, in this embodiment, the side wall mold 100 includes a cone mold shell 101 having a cone inner cavity that is larger at the top and smaller at the bottom; the lower opening of the cone inner cavity of the cone mold shell 101 is arranged downward, so as to be docked with the sealing lifting mechanism 700, thereby lifting the sample cup in the side wall mold 100; the upper opening of the cone inner cavity of the cone mold shell 101 is arranged upward, and the sealing mechanism 800 is suspended above the cone mold shell 101. Optionally, the lower opening size of the cone mold shell 101 is larger than the radial size of the upper end of the sealing lifting rod 703 of the sealing lifting mechanism 700, so that there is a working gap between the two, so as to prevent the sealing lifting rod 703 from abutting or accidentally hitting the side wall mold 100 during the lifting process. The lower opening of the cone inner cavity of the cone mold shell 101 is arranged downward to facilitate the sealing lifting rod 703 to lift and pass through. The sealing lifting rod 703 moves upward and pushes the sample cup in the cone inner cavity of the cone mold shell 101 to rise.

[0048] like Figure 1 , Figure 3 and Figure 7 As shown, in this embodiment, the sealing lifting mechanism 700 includes a sealing lifting fixed support 701, a sealing lifting cylinder 702 fixedly arranged on the sealing lifting fixed support 701 and arranged vertically, and a sealing lifting rod 703 arranged on the movable end of the sealing lifting cylinder 702 and arranged vertically, the upper end of the sealing lifting rod 703 is arranged toward the sealing mechanism 800, and the radial dimension of the upper end of the sealing lifting rod 703 matches the radial dimension of the lower opening of the conical inner cavity of the side wall mold 100. When the side wall mold 100 carries the sample cup containing the coal sample and is transported to the sealing station via the side mold conveying mechanism 400, the sealing lifting cylinder 702 drives the sealing lifting rod 703 to rise to a predetermined stroke, so as to eject the sample cup from the side wall mold 100 to a predetermined height, so as to facilitate the sealing mechanism 800 to perform a clamp-type sealing on the sample cup. Optionally, the predetermined height is less than or equal to 1 / 3 to 3 / 5 of the vertical height of the sample cup; if the sample cup is lifted too high and higher than 3 / 5 of the sample cup height, it is easily affected by external force and easily tipped over, which not only easily leads to sealing failure, but also easily pollutes the sealing area, resulting in the need to stop the machine for cleaning; if the sample cup is lifted too low and lower than 1 / 3 of the sample cup height, the height of the extended area of ​​the sample cup is too small, and it is difficult for the sealing mechanism 800 to seal the sample cup, and it may even contact the side wall mold 100 and hinder the sealing. Optionally, the upper end radial dimension of the sealing lifting rod 703 is smaller than the radial dimension of the lower opening of the cone inner cavity of the side wall mold 100, so that when the sealing lifting rod 703 contacts the bottom of the sample cup, it can be smoothly ejected from the upper opening of the side wall mold 100. Optionally, the sealing lifting cylinder 702 can be replaced by an existing commonly used linear drive device, such as a rodless cylinder, a linear cylinder, a linear gas rod, a linear oil cylinder, a linear motor, a linear servo, etc.

[0049] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, in this embodiment, the sample packaging device 900 includes a packaging transfer mechanism 901 arranged at the side of the sample cup sealing device for receiving the sealed sample cup after sealing and transferring the sealed sample cup to the packaging station by rotating to the sealing station, a sealing cup ejecting mechanism 902 arranged above the sample cup sealing device for passing through the sample cup sealing device and extending from the upper opening of the side wall mold 100 to eject the sealed sample cup from the lower opening of the side wall mold 100 to the packaging transfer mechanism 901 suspended below the side wall mold 100, a sample ball forming pressure rod mechanism 903 arranged above the packaging station for applying an extrusion force from above to squeeze the sealed sample cup into a ball, a sample ball forming pushing mechanism 904 arranged below the packaging station for applying an extrusion force from below to squeeze the sealed sample cup into a ball, and a sample receiving mechanism 905 arranged at the packaging station for receiving the sample ball squeezed into a ball and outputting the sample ball for collection. After the sample cup is sealed at the sealing station, it falls back into the side wall mold 100. The packaging transfer mechanism 901 rotates from the packaging station to the sealing station and hovers below the side wall mold 100 at the sealing station. The sealing cup ejection mechanism 902 extends from the upper opening of the side wall mold 100 and abuts against the sealed sample cup, and then ejects the sealed sample cup in the side wall mold 100 from the lower opening of the side wall mold 100, so that the sealed sample cup falls into the packaging transfer mechanism 901 hovering below, and then The sealed sample cup is transferred to the packaging station by the packaging transfer mechanism 901; the sample ball forming pressure rod mechanism 903 cooperates with the sample ball forming pushing mechanism 904 to press the sealed sample cup on the packaging transfer mechanism 901 that stays at the packaging station up and down, so that the sealed sample cup is pressed into a sample ball, and then the sample ball forming pushing mechanism 904 withdraws downward, and the sample ball forming pressure rod mechanism 903 continues to press downward to send the sample ball into the sample receiving mechanism 905 for collection. Since the sample cup is placed in the side wall mold 100, the sample cup is added, the sample cup is sealed, and the sealed sample cup is output, the sample cup and the side wall mold 100 need to be able to separate freely, and the side wall mold 100 and the side mold conveying mechanism 400 need to be able to separate freely. The side wall mold 100 supports the sample cup by the inner wall, and the side mold conveying mechanism 400 is supported on the outer wall of the side wall mold 100. During these actions, the side wall mold 100 will be subjected to force and deviate from the position on the side mold conveying mechanism 400. Therefore, the sealing lifting mechanism 700 is used. A lifting sample cup is adopted which cooperates with the lower opening gap of the side wall mold 100, and a sealing cup ejection mechanism 902 is used to apply downward force from the top of the side wall mold 100 to eject the sealing sample cup downward from the side wall mold 100, thereby forming an up-and-down force, so that the side wall mold 100 is stably located on the side mold conveying mechanism 400, and the position of the side wall mold 100 on the side mold conveying mechanism 400 is corrected in time through the up-and-down action, ensuring that subsequent processes or circulation processes can be carried out continuously, thereby ensuring the stability and efficiency of the processing production line.Optionally, the outer wall surface of the side wall mold 100 and the side mold conveying mechanism 400 are matched with a conical surface to facilitate the correction of the relative position between the side wall mold 100 and the side mold conveying mechanism 400 while the sealing cup ejection mechanism 902 applies force downward to eject the sealed sample cup, that is, to align the side wall mold 100 coaxially with the bearing positioning hole groove 403. Since the sealing mechanism 800 adopts a clamping method for sealing, and the sample cup that the clamping method seals is tinfoil (metal foil), the sealing position of the sample cup is only temporarily sealed, and is not completely closed and cannot be exhausted. When the sealed sample cup is exhausted under force, the exhaust process is in a state where the seal of the sealed sample cup is facing upward, and the gas will be discharged from the loose position of the sealing position without causing the sealed sample cup to rupture. At the same time, the extrusion force exerted on the sealed sample cup during compression and exhaust must be a force applied slowly after abutting against the sealed sample cup, and stamping cannot be used for exhaust. In addition, for the process of pressing the sealed sample cup into a ball, the deformable nature of tinfoil (metal foil) is fully utilized. When it is completely pressed into a ball, it will be completely and fully sealed and wrapped around the coal sample, so that the protected ball sample will not leak coal samples. That is, the sealing cup pushing rod 9022, the forming pushing rod 9032, and the forming top pushing rod 9042 all slowly approach the sealing sample cup and gradually apply pushing force, and all adopt surface contact with the sealing sample cup, preferably adopt concave arc surface contact.

[0050] like Figure 1 and Figure 3 As shown, in this embodiment, the sealing cup ejection mechanism 902 includes a sealing cup pushing cylinder 9021 arranged vertically at the sealing station with the power output end at the bottom, and a sealing cup pushing rod 9022 arranged at the power output end of the sealing cup pushing cylinder 9021. Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the packaging transfer mechanism 901 includes a rotary drive device 9011, a swing arm 9012 arranged at the power output end of the rotary drive device 9011, and a forming sleeve 9013 arranged on the swing arm 9012, the forming sleeve 9013 includes a conical forming cylinder with a radial dimension of larger upper part and smaller lower part at the upper part, and an extrusion conveying cylinder with equal diameters at the lower part; the sealing cup pushing rod 9022, the side wall mold 100 at the sealing station, and the forming sleeve 9013 rotated to the sealing station are arranged in sequence from top to bottom and coaxially. In the process of transferring the sample cup from the sealing station to the packaging station after sealing, the side mold conveying mechanism 400 rises at the sealing station to facilitate the sealing operation; after sealing, the sealed sample cup falls back into the side wall mold 100, the sealing mechanism 800 and the sealing lifting mechanism 700 are reset to make way for the sealing station, and the rotary drive device 9011 drives the swing arm 9012 to drive the forming sleeve 9013 to rotate from the packaging station to the sealing station, specifically, the forming sleeve 9013 is suspended below the side wall mold 100, and then the sealing cup push cylinder 9013 is pressed. 021 drives the sealing cup pushing rod 9022 downward to press against the sealing sample cup and push the sealing sample cup out from the lower opening of the side wall mold 100 and then drop it into the forming sleeve 9013. The forming sleeve 9013 receives the sealing sample cup in the tapered forming cylinder with a wide mouth at the top. Finally, the swing arm 9012 is driven by the rotary drive device 9011 to drive the forming sleeve 9013 to rotate to the packaging station for packaging the sealed sample cup; at this time, the side mold conveying mechanism 400 continues to operate after descending to package the next group of sample cups. Optionally, the sealing cup pushing rod 9022 and the forming sleeve 9013 hovering below the sealing station are arranged opposite to each other. Optionally, the end of the sealing cup pushing rod 9022 is set to a concave surface, so that the sealing sample cup slides into the concave surface and is pushed out from the lower opening of the side wall mold 100 by the sealing cup pushing rod 9022, so as to avoid an eccentric force on the sealing sample cup, which may squeeze the side wall mold 100 and cause it to break or move the side wall mold 100. Optionally, a flexible cushion layer is attached to the end of the sealing cup pushing rod 9022 to avoid a rigid force on the sealing sample cup. Optionally, the rotary drive device 9011 uses a rotary cylinder.

Optionally, the rod end of the forming push rod 9042 is arranged as a concave spherical surface. The sample receiving mechanism 905 includes a sample receiving guide groove 9051 arranged at the packaging station and a sample receiving bucket 9052 at the output end of the sample receiving guide groove 9051. The forming pushing rod 9032, the forming sleeve 9013 rotated to the packaging station, and the forming pushing rod 9042 are arranged in sequence from top to bottom and coaxially, the inlet of the sample receiving guide groove 9051 is arranged toward the packaging station, the fixed end of the forming pushing cylinder 9041 is penetrated through the sample receiving guide groove 9051, the power output end of the forming pushing cylinder 9041 and the forming pushing rod 9042 are at the inlet position of the sample receiving guide groove 9051 and move up and down at the inlet position, the outlet of the sample receiving guide groove 9051 is inclined radially outward and arranged toward the sample receiving bucket 9052. Optionally, the molding push cylinder 9041 drives the molding push rod 9042 upward and extends from the lower opening of the molding sleeve 9013, and the molding push cylinder 9031 drives the molding push rod 9032 downward to press against the sealed sample cup and press downward, and the molding push rod 9042 cooperates with the molding push rod 9032 to press upward and downward, so that the sealed sample cup is pressed into a ball. Specifically, the molding push cylinder 9041 drives the molding push rod 9042 upward and extends from the lower opening of the extrusion conveying cylinder, and the molding push cylinder 9031 drives the molding push rod 9032 downward and gradually presses the sealed sample cup from the conical molding cylinder to the extrusion conveying cylinder, and the molding push rod 9042 cooperates with the molding push rod 9032 to press upward and downward in the extrusion conveying cylinder, so that the sealed sample cup is pressed into a ball. After the sample ball is formed in the extrusion conveying cylinder, the forming push cylinder 9041 drives the forming push rod 9042 to reset downward and stay in the feeding port of the sample receiving guide groove 9051, and the forming push cylinder 9031 drives the forming push rod 9032 to continue to move downward until the sample ball is pushed out from the lower opening of the extrusion conveying cylinder and falls into the sample receiving guide groove 9051, and is guided to the sample receiving bucket 9052 through the sample receiving guide groove 9051 and collected. The rod end of the forming push rod 9032 is arranged as a concave spherical surface, and / or the rod end of the forming push rod 9042 is arranged as a concave spherical surface, so that it gradually changes into a spherical or quasi-spherical shape when pressing the sealed sample cup, so as to facilitate subsequent detection. Optionally, the rod end of the forming push rod 9032 and / or the rod end of the forming push rod 9042 is set to other concave surfaces, such as a concave cone cavity, a concave frustum cavity, a concave cylindrical cavity, a concave polygonal column cavity, a concave hemispherical cavity, etc.Optionally, a pressure regulating mechanism is provided on the forming push cylinder 9031 and / or the forming push cylinder 9041, and the pressure regulating mechanism is used to adjust the tightness of the sample ball by adjusting the ventilation pressure of the cylinder. Optionally, the packaging tightness of the corresponding waste is obtained by utilizing the packaging process of the waste at the packaging station, and then the required ball forming pressure is obtained, and the ventilation pressure of the cylinder of the sample ball forming pressure rod mechanism 903 and / or the sample ball forming push mechanism 904 is adjusted by the pressure regulating mechanism, and then the required sample ball is obtained.

[0052] like Figure 1 , Figure 8 and Fig. 9As shown, in this embodiment, the coal sample packing equipment also includes a waste sample adding mechanism 1000 that can be rotatably arranged to detect whether the packing process is running normally through waste samples. A waste sample adding station is also arranged between the cup making station and the material loading station, on the material loading station, or between the material loading station and the sealing station; a waste material standby station is also arranged on the side of the waste sample adding station; the waste sample adding mechanism 1000 rotates to the waste sample adding station to add a certain amount of waste material to the sample cup in the waste sample adding station to realize the detection of the packing process, or the waste sample adding mechanism 1000 rotates to the waste material standby station to facilitate the normal operation of the coal sample packing process. The side mold conveying mechanism 400 is used to carry the side wall mold 100, and the side wall mold 100 is sent to the cup making station, the waste material adding station (or the material loading station), and the sealing station one by one in a step-by-step manner through the side mold conveying mechanism 400. More specifically, when the sample packaging test is performed, the material loading station stops working, the side wall mold 100 carrying the empty sample cup is transported to the waste material adding station through the side mold conveying mechanism 400, and the waste sample adding mechanism 1000 is moved from the waste material standby station to the waste material adding station, and after a certain amount of waste is added to the empty sample cup by the waste sample adding mechanism 1000, the waste sample adding mechanism 1000 is reset to the waste material standby station, and then the sample cup is transported to the sealing station by the side mold conveying mechanism 400, and the sample cup is sealed by the sample cup sealing device, and then the sample cup is passed through the packaging device. 900 transfers the sealed sample cup to the packaging station for packaging and output, and collects the ball sample; after the sample packing test confirms that the ball sample is qualified, the waste material adding station stops working and is changed to the material loading station. The side wall mold 100 carrying the empty sample cup is transported to the material loading station through the side mold conveying mechanism 400 for coal sample loading, and then the sample cup is transported to the sealing station through the side mold conveying mechanism 400, and the sample cup is sealed by the sample cup sealing device, and then the sealed sample cup is transferred to the packaging station through the sample packing device 900 for packaging and output, and the ball sample is collected. The control system is electrically connected to the waste sample adding mechanism 1000 and performs coordinated control to realize the orderly operation control of each process and the switching control between the packing test and the sample packing. Coal sampling inspection requires that the weight of coal samples be accurate to 60 mg ± 0.03 mg or 80 mg ± 0.03 mg, and the acquisition of these coal samples requires complicated preliminary procedures. Therefore, each scrapping of coal samples will waste a lot of time and cost. The sample packaging inspection can be carried out by using waste samples to check whether the packaging process is operating normally, so that the entire packaging machine can be debugged into normal operating state during the waste material inspection packaging process, and then determine whether to proceed with the formal coal sample packaging, thereby avoiding the loss of time in the early processing of coal samples, equipment operation loss, coal sample consumption loss, etc. caused by direct coal sample packaging.

[0053] like Figure 1 , Figure 8 and Fig. 9As shown, in this embodiment, the waste sample adding mechanism 1000 includes a waste material adding angle cylinder 1001 for driving in the horizontal direction, a waste material adding support plate 1002 arranged at the power output end of the waste material adding angle cylinder 1001 for rotating and switching between the waste material adding station and the waste material waiting station, a waste material unloading mechanism 1003 arranged on the waste material adding support plate 1002 and rotating and switching between the waste material adding station and the waste material waiting station with the waste material adding support plate 1002, and a waste material inflow pipe 1004 arranged on the waste material unloading mechanism 1003 for replenishing waste. An optical slot sensor 1005 is provided on the waste material adding support plate 1002, and the optical slot sensor 1005 is electrically connected to the control system. The waste material adding angle cylinder 1001 cooperates with the optical slot sensor 1005, and controls the waste material unloading mechanism 1003 to rotate and switch between the waste material adding station and the waste material waiting station through the control system. Optionally, a material unloading opening at the waste adding station is provided on the upper support 601 of the combined support 600, and the material unloading opening is arranged opposite to the side wall mold 100 at the waste adding station. Optionally, a waste collection box is provided at the waste standby station for collecting waste dropped by the waste unloading mechanism 1003 when the waste standby station is in a stopped state. More specifically, when testing the sample package, first ensure that there is enough waste in the waste diversion feeding pipe 1004 (it is sufficient to visually see the waste, or it can be determined whether there is enough waste through common material level sensors, video monitors, etc.). If the waste is missing, it is necessary to add waste to the waste diversion feeding pipe 1004, the material loading station stops working, and the side wall mold 100 carrying the empty sample cup is transported to the waste adding station. The waste adding corner cylinder 1001 drives the waste sample adding support plate 1002 and drives the waste material unloading mechanism 1003 to rotate from the waste standby station to the waste adding station, and then the waste material unloading mechanism 1003 operates to quantitatively unload the waste into the sample cup. Optionally, the waste material unloading mechanism 1003 adopts rotary unloading, and the scraper and mesh can be used to achieve quantitative unloading; or the spiral shaft can be used to rotate and push quantitative unloading.

[0054] like Figure 1 , Figure 8 and Fig. 9As shown, in this embodiment, the waste sample adding support plate 1002 is Z-shaped, the power output end of the waste sample adding corner cylinder 1001 is fixedly connected to the upper horizontal plate of the waste sample adding support plate 1002, and the waste material unloading mechanism 1003 is fixed to the lower horizontal plate of the waste sample adding support plate 1002; the Z-shaped waste sample adding support plate 1002 is adopted to facilitate the structural layout of the waste sample adding mechanism 1000 on the upper bracket 601 of the combined bracket 600, so that the waste sample adding mechanism 1000 can be reasonably arranged above the plate surface of the upper bracket 601, thereby avoiding interference with other structures of the sample packaging machine between the upper bracket 601 and the lower bracket 602. Specifically, the waste material adding angle cylinder 1001 is arranged on the upper bracket 601 and the power output end is arranged upward and fixed to the upper horizontal plate of the waste sample adding support plate 1002. The web of the waste sample adding support plate 1002 is bent downward and fixed to the waste material unloading mechanism 1003 through the lower horizontal plate, so that the waste material unloading mechanism 1003 is suspended above the plate surface of the upper bracket 601, thereby realizing the rotation and switching of the waste material unloading mechanism 1003 between the waste material adding station and the waste material standby station; more specifically, realizing the rotation and switching of the waste material unloading mechanism 1003 between the unloading opening and the waste collection box. Optionally, the caliber of the unloading port of the waste material unloading mechanism 1003 is smaller than the caliber of the unloading opening and smaller than the caliber of the sample cup, so as to ensure that the waste material unloading mechanism 1003 can accurately fall into the sample cup. Optionally, the unloading method of the unloading port is similar to the unloading method of an hourglass. The waste material unloading mechanism 1003 includes a waste material loading head 10031, a mesh plate 10032, a scraper 10033, a reducing shaft 10034, a coupling 10035 and a rotating motor 10036 which are arranged in sequence from bottom to top; the rotating motor 10036 is fixed to the lower horizontal plate of the waste material adding support plate 1002 through a waste material fixing shaft seat 10037, the power output end of the rotating motor 10036 is connected to the first end of the coupling 10035, the second end of the coupling 10035 is connected to the first end of the reducing shaft 10034, and the second end of the reducing shaft 10034 is connected to the first end of the reducing shaft 10034. The two ends are connected to the scraper 10033, and the scraper 10033 is in contact with or has a clearance fit with the mesh plate 10032. The mesh plate 10032, the scraper 10033, the reducing shaft 10034, and the coupling 10035 are all in the inner cavity of the waste fixed shaft seat 10037. The output end of the waste diversion pipe 1004 is connected from the side of the waste fixed shaft seat 10037 to the inner cavity of the waste fixed shaft seat 10037. The waste adding head 10031 is fixedly connected to the lower surface of the lower horizontal plate of the waste sample adding support plate 1002 and is connected to the material output end of the mesh plate 10032.The power output end of the rotating motor 10036 is connected to the reducing shaft 10034 through the coupling 10035, and the reducing shaft 10034 is connected to the scraper 10033 to scrape the waste on the mesh plate 10032, so that the waste is discharged through the mesh holes of the mesh plate 10032 to the waste loading head 10031, and then discharged into the sample cup. On the one hand, the coupling 10035 is used to protect against overload during the driving process (for example, overload is likely to occur when the rotation of the scraper 10033 is blocked); on the other hand, since the amount of material required for the sample cup packaging is very small, the reducing shaft 10034 is used to reduce the size of the output shaft and then reduce the size of the scraper 10033 and the size of the mesh plate 10032, thereby reducing the amount of waste discharged. The waste is added into the waste inlet pipe 1004 and guided into the inner cavity of the waste fixed shaft seat 10037, and the rotating motor 10036 drives the reducing shaft 10034 through the coupling 10035 to drive the scraper 10033 to rotate, so that the scraper 10033 rotates on the surface of the mesh plate 10032, which can not only drive the waste on the surface of the mesh plate 10032 to flow and gradually pass through the mesh plate 10032, but also play a mobile grinding role on the waste on the surface of the mesh plate 10032. Optionally, the aperture of the mesh plate 10032 is 0.05mm~0.5mm, and the size of the aperture is selected according to the particle size of the coal sample and the particle size of the waste, and it is required to gradually and slowly discharge the material when rotating the scraper 10033, and gradually stop discharging the material when the scraper 10033 stops rotating. Optionally, the mesh of the mesh plate 10032 is a cylindrical hole. Optionally, the inner cavity of the waste adding head 10031 is a conical cavity that is larger at the top and smaller at the bottom. The discharge port of the waste adding head 10031 is a conical port and the diameter of the discharge port is greater than or equal to the mesh aperture of the mesh plate 10032, thereby forming an hourglass mouth, so that the waste falling into the inner cavity of the waste adding head 10031 gradually flows into the sample cup. Optionally, the volume of the inner cavity of the waste loading head 10031 matches the amount of waste material that leaks quantitatively into the sample cup. The scraper 10033 is rotated to make the waste material fall and fill the waste loading head 10031, and then the discharge port of the waste loading head 10031 is opened to make the waste material fall. At this time, the discharge port of the waste loading head 10031 does not need to control the aperture, and only needs to be less than or equal to 1 / 2 of the aperture of the sample cup opening and remain coaxial with the sample cup, thereby ensuring that the falling waste material can completely enter the sample cup and is not easily scattered around; and because the sample cup is made of metal foil such as tin foil, and the bottom of the side wall mold 100 is open, the bottom of the sample cup has a certain elastic buffering effect, so that when the waste material falls to the bottom of the sample cup, it is subjected to the elastic buffering effect and is not easily ejected.

[0055] like Figure 1 and Fig.10As shown, in this embodiment, the sample cup manufacturing device includes a bottom support mold group 200 for moving to the lower opening portion of the side wall mold 100 at the cup making station to form the lower bottom wall of the sample cup, and an upper pressing mold group 300 for pressing down into the molding cavity formed by the side wall mold 100 and the bottom support mold group 200 to press and form the sample cup.

The area where the side wall mold 100, the bottom support mold group 200 and the upper pressing mold group 300 cooperate to press the sample cup is the cup making station. Each side wall mold 100 is sequentially transported to the cup making station by the side mold conveying mechanism 400, and at the same time, the material conveying mechanism 500 synchronously delivers the finished cup material to the cup making station in sequence; when the side wall mold 100 is transported to the cup making station, the corresponding finished cup material is also transported to the cup making station and placed on the side wall mold 100, and then the bottom support mold group 200 rises and stays at the lower opening of the side wall mold 100 The upper pressing mold 300 presses down to press the cup material on the side wall mold 100 into the molding cavity to press the sample cup. Finally, the upper pressing mold 300 and the bottom supporting mold 200 are respectively moved away from the side wall mold 100 so that the pressed sample cup stays in the side wall mold 100 and moves downstream with the side mold conveying mechanism 400, and the next side wall mold 100 stays in the cup making station to press and form the sample cup, and the cycle is carried out in sequence. The mold combination can be changed at any time as needed to form sample cups of different shapes and sizes to meet the needs of different sample packaging and increase the application range of the sample cup; the cup material and the side wall mold 100 match and orderly enter the cup making station in sequence, and then press and form the sample cup in sequence.
