[0037] The utility model embodiment provides a package unpacking metering device, referring to Figures 1 to 4 The unpacking and metering device comprises an unpacking component 10, a feeding component 20, a dust collecting component 30 and a metering component 40;
[0038] The unpacking assembly 10 includes an unpacking chamber 11, a first discharge port 12 and an unpacking knife 13. The first discharge port 12 is arranged at the bottom of the unpacking chamber 11 and communicates with the unpacking chamber 11. The unpacking knife 13 is arranged in the unpacking chamber 11. The unpacking knife 13 is configured to unpack the ton bag in the unpacking chamber 11. The first discharge port 12 is configured to guide the powdery material dropped from the ton bag to be discharged out of the unpacking chamber 11 after the unpacking knife 13 unpacks the ton bag.
[0039] The loading assembly 20 is disposed on one side of the unpacking assembly 10, and the loading assembly 20 is configured to transport the ton bag containing the powdered material to the unpacking chamber 11;
[0040] The dust collecting assembly 30 includes a dust collecting chamber 31, a second discharge port 33 and a fan 32. The dust collecting chamber 31 is connected to one side of the unpacking chamber 11. The fan 32 is located above the dust collecting chamber 31 and is configured to collect the powdered materials rising from the unpacking chamber 11 and transport them to the dust collecting chamber 31. The second discharge port 33 is located at the bottom of the dust collecting chamber 31 and communicates with the dust collecting chamber 31, and is configured to guide the powdered materials in the dust collecting chamber 31 to be discharged out of the dust collecting chamber 31.
[0041] The metering assembly 40 includes a metering bin 41 and a metering device 44. The bottom of the unpacking chamber 11 is connected to the top of the metering bin 41, and the first discharge port 12 is connected to the metering bin 41; the bottom of the dust collecting chamber 31 is connected to the side of the unpacking chamber 11 or the top of the metering bin 41, and the second discharge port is correspondingly connected to the unpacking chamber 11 or the metering bin 41. The metering bin 41 is configured to accommodate the powdered material discharged from the unpacking chamber 11 and the dust collecting chamber 31, and the metering device 44 is configured to measure the powdered material in the metering bin 41. For details, see Figure 1 , Figure 2 In the unpacking metering device of the embodiment shown, the bottom of the dust collecting chamber 31 is connected to the side of the unpacking chamber 11, and the second discharge port 33 is connected to the unpacking chamber 11; Figure 3 , Figure 4 In the unpacking and metering device of the illustrated embodiment, the bottom of the dust collecting chamber 31 is connected to the top of the metering bin 41 , and the second discharge port 33 ′ is in communication with the metering bin 41 .
[0042] When the above unpacking and metering device is working, a ton bag containing powdered materials is placed on the loading assembly 20, and the loading assembly 20 transports the ton bag to the unpacking chamber 11 of the unpacking assembly 10, and the unpacking is carried out by the unpacking knife 13. The powdered materials in the unpacking chamber 11 can fall into the metering bin 41 by their own gravity; in addition, the fan 32 of the dust collecting assembly 30 is started during the unpacking process to collect the powdered materials that are lifted and scattered during the unpacking process and transport them to the dust collecting chamber 31; if the bottom of the dust collecting chamber 31 in the unpacking and metering device is connected to the side of the unpacking chamber 11, and the second unloading The opening 33 is connected to the unpacking chamber 11, and the powdered material collected in the dust collecting chamber 31 can pass through the unpacking chamber 11 and then be discharged into the metering bin 41 by its own gravity; if the bottom of the dust collecting chamber 31 in the unpacking metering device is connected to the top of the metering bin 41, and the second discharge opening 33' is connected to the metering bin 41, the powdered material collected in the dust collecting chamber 31 can be directly discharged into the metering bin by its own gravity, and the metering device 44 measures the powdered material in the metering bin 41. When the powdered material in the metering bin 41 reaches a predetermined amount, it is discharged to the rear-end section.
[0043] As described above, the unpacking metering device eliminates the settings of conventional conveying systems such as pipe chains, conveying screws, and negative pressure conveying between the unpacking component 10, the dust collecting component 30, and the metering component 40. By connecting the top of the metering bin 41 of the metering component 40 to the bottom of the unpacking chamber 11 in the unpacking component 10, and the first discharge port 12 of the unpacking chamber 11 is connected to the metering bin 41, the powder in the unpacking chamber 11 can fall directly into the metering bin 41 by its own gravity, thereby avoiding the problems of powder leakage, powder floating, and residual material caused by the conventional conveying system, and can simplify the structure, shorten the process flow, save conveying energy consumption, and reduce costs; in addition, by collecting the powdered materials rising in the unpacking chamber 11 during the unpacking process through the dust collecting chamber 31, it is possible to avoid the occurrence of undesirable situations such as dust pollution and large-area dust diffusion. Since the dust collecting chamber 31 is connected to one side of the unpacking chamber, the powdered material collected in the dust collecting chamber 31 can be discharged into the metering bin 41 through the unpacking chamber 11 or directly discharged into the metering bin 41. There is no need for a conveying system to transport the powdered material in the dust collecting chamber to the metering bin, which is beneficial to reducing the overall volume and cost of the unpacking metering device.
[0044] Specifically, the unpacking assembly 10 in the unpacking metering device is configured to unpack ton bags containing powdery materials, and the unpacking chamber 11 can construct an unpacking environment for the unpacking operation. In order to reduce powder leakage during the unpacking process, a relatively sealed unpacking environment can be constructed through the design of the unpacking chamber 11. For example, in some embodiments, the unpacking chamber 11 can be designed to have a first feed inlet, and a first door can be provided at the first feed inlet. When unpacking, the first door at the first feed inlet of the unpacking chamber 11 can be closed, so that the unpacking operation is carried out in a closed or nearly closed space to prevent the powdery materials from leaking out.
[0045] Among them, the first feed port can be arranged at the top or side of the unpacking chamber to facilitate feeding. The first bin door arranged at the first feed port can be an electric door, an induction door or an automatic reset door to improve the flexibility of the device. For example, the first bin door can be an electric door, which is opened during feeding and closed after feeding; or, the first bin door can be an induction door, which is configured to open when the ton bag is within the induction distance range of the induction door, and close when the ton bag is outside the induction distance range; or, the first bin door can be an automatic reset door, which can be configured to be opened by pushing or pulling, and automatically reset after the pushing or pulling is released, such as the ton bag can be controlled to push the automatic reset door to open during feeding, and after the ton bag enters the unpacking chamber, the pushing force on the automatic reset door is released, and the automatic reset door is reset and closed.
[0046] The bottom of the unpacking chamber 11 in the unpacking assembly 10 is connected to the top of the metering bin 41, and the first discharge port 12 is communicated with the metering bin 41. The metering bin 41 is specifically arranged below the unpacking chamber 11, which may be directly below or to the side, and ensures that the powder in the unpacking chamber 11 can fall into the metering bin 41 by its own gravity.
[0047] The unpacking knife 13 in the unpacking assembly 10 is generally arranged at the bottom of the unpacking chamber 11. Specifically, an unpacking knife with a sharp end facing upward can be used. During the unpacking process, the unpacking knife 13 pierces the bottom of the ton bag with the upward sharp end to achieve unpacking.
[0048] In some embodiments, the unpacking knife 13 may be a W-shaped knife, and the sharp end of the unpacking knife 13 is set upward. Specifically, the unpacking knife in the unpacking chamber 11 may be configured to include at least two W-shaped knives, the sharp end of each W-shaped knife is upward, the sides of each W-shaped knife are connected in sequence and the whole is bent to one side, forming an unclosed bending structure, which is used to tear at least two sides of the bottom of the ton bag. For example, the unpacking knife 13 may include a first W-shaped knife, a second W-shaped knife and a third W-shaped knife with sharp ends facing upward and sides connected in sequence, the first W-shaped knife and the third W-shaped knife are set perpendicular to the second W-shaped knife, and are located on the same side of the second W-shaped knife, so as to tear the bottom of the ton bag on three sides, thereby facilitating complete unpacking and complete material dropping, and improving the unpacking efficiency.
[0049] The loading assembly 20 is configured to transport the ton bag containing powdery materials to the unpacking chamber 11. In some embodiments, the loading assembly 20 includes a vertical guide rail 21, a transverse guide rail 22, and a carrier 23. One end of the transverse guide rail 22 is connected to the top of the vertical guide rail 21, and the other end extends to one side of the unpacking chamber 11. The carrier 23 slides along the vertical guide rail 21 and the transverse guide rail 22 to the unpacking chamber 11 in sequence, that is, the carrier 23 is configured to carry the ton bag and transport it from the vertical guide rail 21 and the transverse guide rail 22 to the unpacking chamber 11 in sequence. When in use, the carrier 23 is placed on the end of the vertical guide rail 21 away from the transverse guide rail 22, and the ton bag containing powdery materials is placed on the carrier 23. The carrier 23 carries the ton bag and transports it from the vertical guide rail 21 and the transverse guide rail 22 to the unpacking chamber 11 in sequence, thereby achieving loading. The carrying device 23 cooperates with the vertical guide rail 21 and the transverse guide rail 22. The carrying device 23 carries and transports ton bags along the guide rails. Compared with loading methods such as cranes and hoists, it is more stable and reliable and can reduce the risk of falling.
[0050] In addition, in some embodiments, the carrier 23 is further configured to extract the ton bag and drive the ton bag to move into the unpacking chamber 11, and drive the ton bag to descend in the unpacking chamber 11 so that the ton bag abuts against the unpacking knife 13, so as to realize the feeding and unpacking of the unpacking chamber in the unpacking assembly 10. In addition, the carrier 23 can be designed to be further configured to return the unpacked empty bag along the original feeding path to the feeding starting end.
[0051] When the unpacking component 10 is unpacking, most of the powdered materials are unloaded through the first unloading port 12 under their own gravity, but some powdered materials will rise, float and be in a suspended state. Through the setting of the dust collecting component 30, the powdered materials that rise in the unpacking chamber 11 when the unpacking component 10 is unpacking can be collected.
[0052] The dust collecting chamber 31 in the dust collecting assembly 30 is connected to one side of the unpacking chamber 11. Specifically, the unpacking chamber 11 and the dust collecting chamber 31 can be designed to be spaced apart, or the dust collecting chamber 31 can be designed to be close to one side of the unpacking chamber 11. In some embodiments, the dust collecting chamber 31 can be arranged on the side of the unpacking chamber 11 that is away from the transverse guide rail 22. The unpacking chamber 11 has a dust discharge port, and the dust collecting chamber 31 has a second feed port. The dust discharge port of the unpacking chamber 11 is connected to the second feed port of the dust collecting chamber 31. In order to facilitate the collection of powdered materials that rise when the unpacking chamber 11 is unpacked and avoid the interference of unpacking and falling materials, the dust discharge port of the unpacking chamber 11 can be arranged at the middle and upper end of the unpacking chamber 11.
[0053] The bottom of the dust collecting chamber 31 is connected to the side of the unpacking chamber 11 or the top of the metering bin 41 , and the second discharge port is communicated with the unpacking chamber 11 or the metering bin 41 .
[0054] Specifically, refer to Figure 1 and Figure 2 In some embodiments, the dust collecting chamber 31 can be designed to be connected to the side of the unpacking chamber 11, the second discharge port 33 of the dust collecting chamber 31 is in communication with the unpacking chamber 11, the unpacking chamber 11 is also configured to accommodate the powdered materials discharged from the second discharge port 33, and the metering bin 41 is configured to receive the powdered materials discharged from the first discharge port 12, that is, the powdered materials collected by the dust collecting chamber 31 are discharged from the second discharge port 33 into the unpacking chamber 11, and the powdered materials discharged from the first discharge port 12 enter the metering bin 41. Through the above structural arrangement, the powdered materials collected by the dust collecting chamber 31 can be discharged from the second discharge port 33 into the unpacking chamber 11 by its own gravity, and the powdered materials in the unpacking chamber 11 (including the unpacking materials of the unpacking chamber 11 and the powdered materials discharged from the dust collecting chamber 31) are discharged from the first discharge port 12 of the unpacking chamber 11 into the metering bin 41 by its own gravity.
[0055] Among them, the lower end side wall of the dust collecting chamber 31 can be designed as a material guiding structure inclined toward the unpacking chamber 11, so that the material in the dust collecting chamber 31 falls into the unpacking chamber 11 by gravity; and / or, the bottom of the unpacking chamber 11 can be designed as a funnel structure to facilitate the unloading of materials from the unpacking chamber 11.
[0056] In addition, in order to ensure that the powdered materials collected in the dust collecting chamber 31 can fall smoothly into the unpacking chamber 11, and reduce the confusion between the feed port and the discharge port when the fan 32 collects the powdered materials rising in the unpacking chamber 11, thereby affecting the unloading of the dust collecting chamber 31, the connection position of the second discharge port 33 of the dust collecting chamber 31 and the unpacking chamber 11 can be designed to be located at the lower part of the unpacking chamber 11 near the first discharge port 12, and lower than the setting position of the feed port of the dust collecting chamber 31.
[0057] See also Figure 3 and Figure 4 , Figure 3 and Figure 4 The schematic diagram and partial schematic diagram of the structure of another embodiment of the unpacking metering device of the utility model are respectively shown. Figure 1 , Figure 2 The main difference between the unpacking and metering devices shown is the connection relationship between the unpacking chamber 11, the dust collecting chamber 31 and the metering bin 41, and the corresponding unloading method of the dust collecting chamber 31. In this embodiment, the bottom of the unpacking chamber 11 is connected to the top of the metering bin 41, and the first discharge port 12 is connected to the metering bin 41; and the bottom of the dust collecting chamber 31 is connected to the top of the metering bin 41, and the second discharge port 33' is connected to the metering bin 41. The metering bin 41 is configured to receive the powdered material discharged from the first discharge port 12 and the powdered material discharged from the second discharge port 33', that is, the powdered material collected by the dust collecting chamber 31 is discharged from the second discharge port 33' into the metering bin 41, and the powdered material discharged from the first discharge port 12 enters the metering bin 41. Through this structural setting, the powdered material in the unpacking chamber 11 and the powdered material in the dust collecting chamber 31 can be directly discharged from the first discharge port 12 and the second discharge port 33' into the metering bin 41 respectively by their own gravity. The metering bin 41 may be specifically disposed below the dust collecting chamber 31 , which may be directly below or to the side below, and ensures that the powdered material in the dust collecting chamber 31 can directly fall into the metering bin 41 by its own gravity.
[0058] The metering device 44 is configured to meter the powdered material in the metering bin 41. Specifically, the powdered material unpacked by the unpacking component 10 falls directly into the metering bin 41 of the metering component 40 under the action of its own gravity, and the powdered material collected by the dust collecting chamber 31 passes through the unpacking chamber 11 or is directly discharged into the metering bin 41 under the action of its own gravity. The metering device 44 in the metering component 40 can meter the powdered material falling into the metering bin 41 without manual metering operation, thereby improving processing efficiency and saving labor costs; at the same time, the powdered material collected by the dust collecting component 30 falls directly or indirectly into the metering bin 41 under its own gravity, which will not cause the loss of powdered material and avoid waste of resources.
[0059] The metering device 44 can be a weight metering device or a volume metering device. For example, in some embodiments, the metering device 44 is a weight weighing device, which is configured to weigh and measure the powdered material in the metering bin 41. In some embodiments, the metering device 44 can be a volume metering device, which is configured to measure the volume of the powdered material in the metering bin 41.
[0060] Reference Figure 1 and Figure 3 In some embodiments, the metering assembly 40 further includes a guide rod 42 and a motor 43. The guide rod 42 is at least partially inserted into the metering bin 41. The motor 43 is installed in the metering bin 41 and is in transmission connection with the guide rod 42 to drive the guide rod 42 to rotate. During use, when the powdered material in the metering bin 41 accumulates to a certain amount and is unloaded, the motor 43 can be started to drive the guide rod 42 to rotate, so as to stir the material in the metering bin 41, provide the flow power of the powdered fluid, and prevent the packaged fluid in the metering bin 41 from bridging and hardening, so as to achieve efficient unloading. In addition, since the conventional unloading methods such as air hammers and air shocks are used, serious noise will be generated, which will seriously affect the work of the operators, reduce the work efficiency of the operators, and increase the labor cost. By using the motor 43 and the guide rod 42 to assist unloading, excessive use of air hammers and air shocks can be avoided, energy consumption can be reduced, and a good working environment can be provided for production.
[0061] In some embodiments, the guide rod 42 is a spiral rod, and the guide rod 42 is hollow. Because the powder material generally has a small particle size and a large bulk density, the use of a hollow spiral guide rod can reduce the movement resistance of the guide process, reduce the burden of the motor 43, prevent excessive load, and improve the reliability of the device, which is more advantageous than using a blade-type guide rod.
[0062] The motor 43 can be installed above the top of the metering bin 41, and the guide rod 42 extends downward from the top of the metering bin 41 into the metering bin 41, and the top of the guide rod 42 is connected to the motor 43. Through the above design, the motor 43 can drive the guide rod 42 to rotate along the unloading direction of the metering bin 41, which can improve the unloading efficiency.
[0063] In some embodiments, a gap can be controlled between the bottom end of the guide rod 42 and the bottom of the metering bin 41; and / or, the length of the guide rod 42 passing through the metering bin 41 is greater than half the height of the metering bin 41 and less than the height of the metering bin 41, so as to ensure that the guide rod 42 can be fully inserted into the powdered material accumulated in the metering bin 41, thereby achieving effective material guiding and reducing the burden on the motor 43.
[0064] In order to improve the flexibility of the device, in some embodiments, the metering component 40 also includes a third discharge port and a second bin door. The third discharge port is arranged at the bottom of the metering bin 41 and is connected to the metering bin 41, and is configured to guide the powdered material in the metering bin 41 to be discharged out of the metering bin 41; the second bin door is arranged at the third discharge port and is configured to open or close the third discharge port.
[0065] In some embodiments, the unpacking metering device may be designed to further include a controller, which is at least used to control the bin door to open or close the third discharge port according to feedback information from the metering device 44 .
[0066] In addition, the controller can also be configured to control the loading component 20, the unpacking component 10 and the dust collection component 30, and control and adjust the set operating parameters of the unpacking metering device. The controller acts as a central control system to control each component, realize the mutual connection between the components, and issue an alarm warning when the equipment is in a bad state or fails, and automatically stop running. If the rear-end operating component is in a bad state after the loading component 20 is loaded, the controller can control the loading component 20 to stop running, wait for the rear-end operating component to stabilize, and the operating component sends a command to the controller to confirm whether the equipment can operate normally, reduce the safety risks brought by the equipment, and prevent workers from operating improperly, which has a certain degree of fool-proofing. In this way, the degree of automation and safety factor of the device can be improved, and the maintenance cost of the equipment can be reduced.
[0067] In some embodiments, the unpacking metering device may further include an activation device 50, which has a feed port, and the feed port is connected to the third discharge port of the metering bin 41. Specifically, the activation device 50 may be an activation hopper, the bottom of which is funnel-shaped, which can guide the discharge of the material to improve the discharge efficiency and prevent the powder from bridging, agglomeration, and compaction.
[0068] In addition, based on the position difference of the component structure in the unpacking metering, an additional mounting bracket can be configured to install and fix the unpacking metering device.
