Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of material containers, and more particularly to a packaging device for solid materials. Background Art
[0002] Pharmaceutical and chemical production often uses a large number of solid materials, such as pharmaceutical raw materials. These solid materials are often packaged in large quantities. These large packages often need to be subpackaged for use in multiple batches. However, many solid materials are irritants, prone to static electricity, and generate dust. The subpackaging process can easily generate dust in the production area, causing pollution and significant health hazards to production personnel, posing a significant safety hazard. Therefore, large packages of solid materials are often subpackaged and handled in glove boxes to avoid these hazards and risks.
[0003] However, in the actual operation of packaging large packages of solid materials in a glove box, the solid materials before packaging are often very heavy, such as over 50 kg. To facilitate operation, the operating platform of the glove box is usually relatively high, usually over 1 meter. Therefore, it takes a lot of strength to load the solid materials into the glove box. Moreover, during the solid material's ascent and transfer, the body or clothing may come into contact with the solid material, which is unsafe. If the solid material packaging is scratched during this process, causing leakage, the consequences can be disastrous.
[0004] Therefore, the art still lacks a packaging device for solid materials that can overcome the above problems, so as to save time and effort in transporting heavier solid materials to be packaged upward to the operating space, and perform packaging operations in a manner that isolates operators from the solid materials, thereby improving operational safety.

[0082] After extensive and in-depth research and a large amount of screening, the inventors have developed for the first time a packaging device for solid materials. The packaging device of the utility model is particularly suitable for the loading process from bottom to top. Through the mutual cooperation between the receiving part, the conveying part and the actuating assembly, the solid material can be transported to the glove box in a time-saving and labor-saving manner, and the contact between the operator and the solid material is reduced, which has good safety. The utility model was completed on this basis.
[0083] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are intended only to illustrate the present invention and are not intended to limit the scope of the present invention. Furthermore, the accompanying drawings are schematic diagrams, and therefore the devices and apparatus of the present invention are not limited by the dimensions or proportions of the schematic diagrams.
[0084] It should be noted that in the claims and description of this patent, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "including a" does not exclude the presence of other identical elements in the process, method, article or device that includes the element.
[0085] Example 1
[0086] The solid material packaging device of this embodiment is as follows Figure 1As shown. The packaging device includes a box body 1, and the box body 1 can form a closed space (i.e., an operating space), in which solid materials placed therein can be operated. The box body 1 has a glass window 17, through which the situation in the closed space can be seen. In another preferred embodiment, the glass window 17 is connected to the box body 1 by sealing rings on all sides to increase the airtightness. In another preferred embodiment, the glass window 17 is openable and closable. Two operating gloves 18 are provided on the glass window 17, and the operator's hands can be inserted into the auxiliary operating gloves 18 to operate the items in the closed space. The two operating gloves 18 and the glass window 17 are also sealed by a sealing ring. An air supply duct (not shown) is provided on the side wall of the box body 1 (e.g., the side wall opposite the side wall where the glass window 17 is located), and a dust removal filter 11 is provided at the top of the box body 1. The air supply duct and dust removal filter 11 guide the airflow into the enclosed space and suck out the floating raw material powder in the enclosed space. On the one hand, this prevents the floating powder from blocking the operator's vision, and on the other hand, it prevents safety hazards such as explosions caused by excessive dust concentration in the enclosed space, and also ensures that the enclosed space is kept as clean as possible. The solid material powder sucked out through the air inlet and outlet ducts can be recycled and reused. The box body 1 is also equipped with a pressure gauge 12, which is used to detect the pressure value in the operating space. The pressure value in the operating space is maintained at atmospheric pressure by controlling the air volume of the air supply duct and the air volume of the dust removal filter 11. After the solid material is packaged, the dust removal filter 11 and the air supply duct continue to operate for a period of time to remove as much solid material dust as possible from the operating space. The door panel 14 is then opened to remove the packaged solid material. The box body 1 is also provided with a cleaning gun 13, which is in fluid communication with the operating space and is used to spray cleaning liquid to clean the operating space. The cleaning operation is usually performed while the subpackaging device is idle. The corresponding lower part of the box body 1 is provided with a drain port (not shown), and the waste liquid after flushing is discharged through the drain port. A waste bin (not shown) is also provided at the lower part of the box body 1. The waste bin can be used to accommodate unnecessary solid material packaging bags / boxes and other garbage to facilitate subsequent centralized processing, such as centralized destruction of packaging bags of corrosive or toxic raw materials. The bottom of the box body 1 is supported by a frame 10, so that the bottom surface of the box body 1 is 0.8-1.5m from the ground; preferably, 1.0-1.2m. Rollers 19 can be optionally provided at the bottom of the frame 10 to meet the needs of movement.
[0087] A material inlet (obstructed by a door panel 14 in the figure) is provided on the side wall of the box body 1 (different from the side wall where the glass window 17 is located). The material inlet is controlled to be closed or to form a passage by controlling the opening and closing of the door panel 14. In this embodiment, the door panel 14 is connected to the door cylinder 15, and the vertical movement of the door panel 14 is controlled by the extension and contraction of the door cylinder 15, thereby controlling the positional relationship of the door panel 14 relative to the material inlet, thereby realizing the opening and closing control of the material inlet. A pair of guide rails 16 are provided on the side wall, and the two ends of the door panel 14 are confined in the pair of guide rails 16, thereby limiting the door panel 14 to slide only along the guide rails 16. In another preferred embodiment, a sealing gasket is provided on the door panel 14 to improve the airtightness of the enclosed space when the door panel 14 is closed. Of course, the door panel 14 may also be in a hinged form and / or a snap-fit mode, etc., for example, similar to a door or window that is hinged and fixed on one side, such as a door or window that is snap-fitted by rotating a handle, etc., as long as the opening and closing of the material inlet can be controlled by the door panel 14, and the material inlet has an inlet area that allows solid material to enter in the passage state.
[0088] The loading device includes a receiving member 2, a conveying member and an actuating assembly. The actuating assembly includes a pivot connecting member 6 and an actuating cylinder 5. The pivot connecting member 6 includes a pair of first ears 7 arranged on the same side of the frame 10 as the door panel 14, and the middle parts of the pair of first ears 7 are each provided with a first through hole, and a pair of second ears 8 arranged on a side frame 3 of the conveying member, and the middle parts of the pair of second ears 8 are each provided with a second through hole. The first through hole and the second through hole are connected by a pivot 9, so that the conveying member can rotate around the pivot 9. There are two actuating cylinders 5, one end of the pair of actuating cylinders 5 is fixedly connected to the middle section or the near section of the frame 3 of the conveying member (for example, the two side frames 3 perpendicular to the side where the second ears 8 are located), and the other end is fixed to the lower part of the frame 10 for supporting the box body 1. The actuating cylinder 5 can provide an upward and outward thrust to push the far end of the conveying member to rotate upward. The conveying member includes four frames 3 and a plurality of rollers 4 fixed on the frames 3, and the axial direction of the rollers 4 is the same as the axial direction of the pivot 9. The rollers 4 are rotatable, and solid materials can be placed on the plurality of rollers 4 and moved by the rotation of the rollers 4. The other side of the conveying member opposite to the second ear 8 is fixedly connected to the receiving member 2. Preferably, the receiving member 2 is perpendicular to the plane where the conveying member is located. It should be noted that the connection relationship between the conveying member and the frame 10 is not limited to the above description, and it can be other connection relationships other than the above connection relationship, as long as the far end of the conveying member can be rotated by at least 90 degrees. For example, the pair of first ears 7 are respectively provided with grooves, and the proximal end of the conveying member is provided with a rotating shaft, and the two ends of the rotating shaft are respectively accommodated in the pair of grooves, and the rotating shaft can rotate in the groove, and so on.
[0089] During use, in the initial state, the conveyor member is positioned perpendicular or nearly perpendicular to the ground (this configuration minimizes the footprint of the loading device when not in use), and the receiving member 2 extends from the side of the conveyor member opposite the second ear portion 8, away from the glove box body 1. This is the loading state, and solid materials can be placed on the receiving member 2. In another preferred embodiment, a pair of baffles are provided between the receiving member 2 and the conveyor member. These baffles, the receiving member 2, and the conveyor member define an enclosure for containing solid materials, preventing the solid materials from moving outside the enclosure. In the subsequent motion state, the actuating cylinder 5 pushes the conveyor member to rotate upward about the pivot 9. Under the shielding of the receiving member 2, the solid materials move upward along the distal end of the conveyor member (the end distal from the box body 1). When the conveyor member's plane is parallel to the ground or the distal end of the conveyor member is higher than the proximal end of the conveyor member, the solid materials are moved toward the box body 1 to the vicinity of the door panel 14 by the rotation of the roller 4. Simultaneously, the door panel 14 opens, allowing the solid materials to enter the enclosed space, and the door panel 14 closes. After use, the actuating cylinder 5 of the loading device is withdrawn and the conveying member is rotated downward to return to the initial position.
[0090] Example 2
[0091] The solid material packaging device of this embodiment is as follows Figure 2 The glove box of this embodiment is similar to that of embodiment 1, except that the loading device is different.
[0092] In this embodiment, the loading device still includes a receiving member 2, a conveying member and an actuating assembly.
[0093] The conveying member in this embodiment includes a first conveying member 20 and a second conveying member 21, wherein the structures of the first conveying member 20 and the second conveying member 21 are similar to those of the conveying member in Example 1, both being in the form of four frames 3 and a plurality of rollers 4. In the initial state, the first conveying member 20 is no longer perpendicular to the ground, but is inclined at a certain angle (for example, 30-60 degrees) to the ground; the second conveying member 21 is arranged horizontally or tilted downward, and the proximal side of the second conveying member 21 is fixed at a position near the bottom of the material inlet. In another preferred embodiment, the distal end of the second conveying member 21 can be supported by a support rod to increase its stability and load-bearing capacity. The length of the second conveying member 21 is approximately 25%-50% of the length of the first conveying member 20; preferably, 30%-40%; more preferably, 33%-36%.
[0094] The structure of the receiving member 2 in this embodiment is similar to that in Example 1. The receiving member 2 in this embodiment is disposed at the distal end of the first conveying member 20. Since the first conveying member 20 in this embodiment is not disposed vertically as in Example 1, the angle between the receiving member 2 and the first conveying member 20 in this embodiment can be greater than 90 degrees, for example, within the range of 80-120 degrees.
[0095] The first ear portion 7 of the pivot connection member 6 is arranged on the framework 10, and the second ear portion 8 is arranged on the middle section or near section of the frame 3 (for example, the two side frames 3 vertical to the roller 4) of the first conveying member 20. The first ear portion 7 and the second ear portion 8 are still connected into one by the pivot 9. The first conveying member 20 can rotate around the pivot 9. The number of the actuating cylinder 5 is one or two. One end of the actuating cylinder 5 is fixedly connected with the proximal frame 3 of the first conveying member 20, and the other end is fixed on the lower surface of the box body 1 or on the top of the framework 10 that is used to support the box body 1. The actuating cylinder 5 can provide downward (and inward) thrust, and the proximal end of the first conveying member 20 is pressed downward, and the distal end of the corresponding first conveying member 20 is tilted upward, and as a fulcrum, forms a structure similar to a seesaw by the pivot 9.
[0096] In the case where the angle of inclination between the conveying member and the bottom surface is small and the conveying member is long, an extension frame (not shown) may also be included. The extension frame is a portion extending from the main body of the frame 10 supporting the box body 1, which is used to support the first conveying member 20. Rollers can also be set at the bottom of the extension frame as needed. The height of the extension frame is 40%-70% of the height of the main body of the frame 10 supporting the box body 1; preferably, 40%-65%; more preferably, 45%-50%. When the extension frame is set, the first ear 7 of the pivot connecting member 6 is set on the extension frame (for example, on the free end of the extension frame) instead of on the main body of the frame 10, and the second ear 8 is set in the middle section or near section of the frame 3 of the first conveying member 20 (for example, the two side frames 3 perpendicular to the roller 4). The first ear 7 and the second ear 8 are still connected into one piece by the pivot 9. The first conveying member 20 can rotate around the pivot 9.
[0097] During use, in the initial state, the distal end of the first conveying member 20 touches the ground, and the receiving member 2, the first conveying member 20, and the optional baffle form an enclosure space for holding solid materials. This is the state to be loaded, and the solid materials can be placed in the enclosure space. In the subsequent motion state, the actuating cylinder 5 pushes the proximal end of the first conveying member 20 downward, and the solid materials move upward with the distal end of the first conveying member 20. When the actuating cylinder 5 reaches the end of its stroke or approaches the end of its stroke, the distal end of the first conveying member 20 rises to a height similar to or exceeding the height of the distal end of the second conveying member 21, and the distal ends of the first conveying member 20 and the second conveying member 21 are against or very close to each other. The solid materials move from the distal end of the first conveying member 20 to or slide onto the second conveying member 21 as the roller 4 rolls, and are moved toward the box body 1 to the vicinity of the door panel 14 by the rotation of the roller 4 of the second conveying member 21. At the same time, the door panel 14 is opened, and the solid materials enter the enclosed space, and the door panel 14 is closed. After use, the actuating cylinder 5 of the loading device is withdrawn, and the first conveying member 20 is rotated back to the initial position.
