[0003] During the loading process, since the material is easily adsorbed on the inner wall of the ton bag, if the material on the inner wall of the ton bag cannot be removed, a large amount of material will be discarded along with the waste ton bag, resulting in a large amount of material loss.

[0041] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0042] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0043] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0044] In order to solve the technical problem in the prior art that a lot of material remains on the inner wall of the ton bag 7, which easily causes a large amount of material loss, the present application provides a suction device, which can realize continuous shaking of the inner wall of the ton bag 7 through the vibration component 42 arranged on the bag-beating mechanism 4, and can shake the material adsorbed on the inner wall of the ton bag 7 to the bottom of the ton bag 7, so as to facilitate the suction mechanism 1 to suck the material, and can effectively reduce the material loss when loading through the ton bag 7 and the suction mechanism 1.

[0045] See also Figures 1 to 8 The embodiment of the present application provides a material suction device, including a material suction mechanism 1, a lifting mechanism 2, a mounting frame 3 and a bag-beating mechanism 4. The material suction mechanism 1 includes a connected suction gun assembly 11 and a lifting assembly 12. The height position of the suction gun assembly 11 can be adjusted by the lifting assembly 12, so that the suction gun assembly 11 can move inside the ton bag 7, so that the suction gun assembly 11 can effectively suck the material as the height position of the material changes; the lifting mechanism 2 includes a plurality of lifting assemblies 21 arranged in sequence along the circumference of the material suction mechanism 1, and the lifting assembly 21 is used to connect with the ton bag 7, and a plurality of connection points can be formed in the circumference of the ton bag 7 for adjusting the height position of the ton bag 7; the material suction mechanism 1 and the lifting mechanism 2 are arranged on the mounting frame 3, and the middle part of the mounting frame 3 has a storage space for accommodating the ton bag 7, which is convenient for lifting The lifting mechanism 2 lifts the edge or four sides of the ton bag 7 to facilitate the suction mechanism 1 to extend into the middle of the ton bag 7 to suck the material; the bag-beating mechanism 4 includes a swing arm assembly 41 and a vibration assembly 42, and multiple swing arm assemblies 41 are arranged in sequence along the circumference of the mounting frame 3. The free end of the swing arm assembly 41 is arranged toward the accommodating space, and the free end is provided with a vibration assembly 42. When the ton bag 7 needs to be beaten, it is only necessary to move the vibration assembly 42 to fit the outer surface of the ton bag 7 through the swing arm assembly 41, and the vibration of the vibration assembly 42 drives the ton bag 7 to shake continuously, so that the material adsorbed on the inner wall of the ton bag 7 is shaken off to the bottom of the ton bag 7, which is convenient for the suction mechanism 1 to absorb the material and reduce the material residue inside the ton bag 7. The material loss during feeding through the ton bag 7 and the suction mechanism 1 can be effectively reduced.

[0046] It should be noted that the number of lifting components 21 is two or more, and the lifting positions of each lifting component 21 can be the same or different. When the lifting positions of each lifting component 21 are different, the ton bag 7 is tilted, and the ton bag 7 is repeatedly tilted through multiple lifting components 21. Even if the ton bag 7 swings, the position of the material inside the ton bag 7 can be adjusted to avoid the situation of material bridging inside the ton bag 7. The material can be gathered to the middle of the ton bag 7, which is convenient for the suction mechanism 1 to suck it.

[0047] In a preferred embodiment of the present application, four lifting assemblies 21 are arranged at the four corners or four sides of the mounting frame 3 , and the four corners of the ton bag 7 are lifted by the four lifting assemblies 21 .

[0048] In some embodiments of the present application, in order to make the vibration component 42 fit on the outer surface of the ton bag 7, the ton bag 7 can produce continuous shaking, see Figure 2 and Figure 3 The vibration assembly 42 includes a high-frequency vibrator 421 and a vibration plate 422. When the high-frequency vibrator 421 is turned on, it can drive the vibration plate 422 to continuously vibrate at a high frequency. The vibration plate 422 is attached to the outer surface of the ton bag 7, and can drive the ton bag 7 to continuously vibrate at a high frequency, so that the materials on the inner wall of the ton bag 7 are shaken off. In order to enhance the adhesion effect between the vibration plate 422 and the outer surface of the ton bag 7, the vibration plate 422 is preferably an arc plate or a C-shaped plate, which can increase the contact area between the vibration plate 422 and the ton bag 7.

[0049] In order to adjust the position of the vibration assembly 42 relative to the big bag 7 through the swing arm assembly 41, in some embodiments of the present application, refer to Figure 2 and Figure 3 The swing arm assembly 41 includes a driving member 411 and a swing arm member, and the swing arm member is hinged on the mounting frame 3; the swing arm member includes a first swing arm 412 and a second swing arm 413 connected at an angle, the first swing arm 412 is connected to the driving member 411, and the second swing arm 413 is connected to the vibration assembly 42. When the driving member 411 drives the first swing arm 412 to move, the second swing arm 413 drives the vibration assembly 42 to move closer to or away from the ton bag 7.

[0050] In some embodiments of this application, please refer to Figure 3 The first swing arm 412 and the second swing arm 413 are connected to form an L-shaped structure. The right-angle portion of the L-shaped structure is hinged to the mounting frame 3. The driving member 411 is a driving cylinder or a driving oil cylinder. One end of the driving member 411 is hinged to the mounting frame 3, and the other end of the driving member 411 is hinged to the first swing arm 412. When the driving member 411 is extended or retracted, it can push the first swing arm 412 to rotate around the right-angle portion, so that the second swing arm 413 drives the vibration assembly 42 to rotate around the right-angle portion, so that the vibration assembly 42 is close to or away from the ton bag 7.

[0051] It should be noted that in the prior art, the driving component used to drive the connecting rod mechanism to beat the ton bag 7 needs to continuously reciprocate so that the connecting rod mechanism can beat the ton bag 7 at a certain frequency, while the driving member 411 in the present application only needs to move when adjusting the position of the vibration component 42 relative to the ton bag 7, and does not need to perform frequent reciprocating motions. While improving the shaking effect on the ton bag 7, the service life of the driving member 411 can be increased. When the vibration component 42 fails, the present application can still drive the vibration plate 422 to beat the ton bag 7 through the swing arm component 41, which is more practical.

[0052] In order to realize automatic bag breaking of the ton bag 7, in some embodiments of the present application, please refer to Figure 1 , Figure 4 and Figure 6 The suction device also includes a bag breaking mechanism 5, which is connected to the bottom of the suction mechanism 1. The bag breaking mechanism 5 has a channel for extending the suction gun assembly 11. Specifically, the channel is located in the middle of the bag breaking mechanism 5. Before breaking the bag, the position of the suction gun assembly 11 is lifted by the lifting assembly 12, so that the suction port 1112 of the suction gun assembly 11 is located above the bag breaking mechanism 5 or inside the bag breaking mechanism 5; the bag breaking mechanism 5 includes a bag breaking assembly 51 and a dust removal assembly 52 arranged in sequence from bottom to top. When the lifting assembly 21 lifts the ton bag 7 upward, the upper surface of the ton bag 7 first contacts the bag breaking assembly 51, and the bag breaking assembly 51 breaks the top of the ton bag 7 to form a suction gap at the top of the ton bag 7. During the bag breaking process, the dust and debris of the ton bag 7 in the bag breaking process are collected by the dust removal assembly 52 to prevent the debris of the ton bag 7 from being sucked into the suction gun assembly 11 during the suction process, thereby affecting the subsequent production process and production quality.

[0053] In some embodiments of this application, please refer to Figure 4 and Figure 6 The bag breaking assembly 51 includes a bag breaking knife 511 with a sharp portion, and a dust suction chamber is formed between the bag breaking knife 511 and the outer wall of the suction gun assembly 11. The dust suction chamber is connected to the dust removal assembly 52. ​​After the bag is broken, dust and debris can enter the dust removal assembly 52 through the dust suction chamber, which is convenient for collecting dust and debris.

[0054] It should be noted that the bag breaking knife 511 is a tubular structure, and the sharp part can be a circular arc blade or a triangular blade extending downward. When the lifting assembly 21 lifts the ton bag 7 upward, the ton bag 7 moves relative to the sharp part, which facilitates the insertion of the sharp part into the ton bag 7 and forms a material suction notch at the top of the ton bag 7.

[0055] In some embodiments of this application, please refer to Figure 6 The dust removal assembly 52 includes a dust cover 521 disposed around the outer periphery of the suction gun assembly 11, the dust cover 521 is connected to the dust suction chamber, and a connecting portion 522 for connecting to a fan is provided on the dust cover 521. The fan generates negative pressure inside the dust cover 521 and the dust suction chamber, and dust and debris are collected and transferred by negative pressure adsorption. Specifically, the connecting portion 522 is a connecting pipe that can be connected to the negative pressure pipeline of the fan.

[0056] In some embodiments of this application, please refer to Figure 6 The bag breaking assembly 51 also includes a clamp 512, which is clamped on the outside of the bag breaking knife 511 and the dust cover 521 to achieve a detachable connection between the bag breaking knife 511 and the dust cover 521. When the bag breaking knife 511 is damaged, the bag breaking knife 511 can be replaced, which is beneficial to reducing the maintenance cost of the suction device.

[0057] In order to prevent the suction gun assembly 11 from being blocked during the suction process, in some embodiments of the present application, please refer to Figure 4 and Figure 5 The suction gun assembly 11 includes a suction pipe 111 and an air supply pipe 112. The suction pipe 111 is coaxially arranged inside the air supply pipe 112. The suction pipe 111 has an air supply hole 1111 for communicating with the air supply pipe 112. During the suction process, the suction pipe 111 can be air-supplemented through the air supply pipe 112 and the air supply hole 1111 to avoid blockage inside the suction pipe 111.

[0058] It should be noted that the air supply pipe 112 can be connected to the air supply fan alone, or can share a fan with the dust removal component 52. In some embodiments of the present application, please refer to Figure 7 A plurality of connecting holes 1121 are provided on the upper side wall of the air supply pipe 112, so that the air supply pipe 112 is connected to the dust removal hood 521. Air can be supplied through a fan connected to the dust removal hood 521, which can reduce the number of fans in the suction device and simplify the fan control system in the suction device.

[0059] In order to prevent the suction port 1112 of the suction pipe 111 from being blocked when sucking materials, in some embodiments of the present application, refer to Figure 5 The suction pipe 111 has a trumpet-shaped suction port 1112, and the side wall of the suction port 1112 has a hollow structure to prevent the suction port 1112 from being blocked. Specifically, the suction port 1112 is a frame structure formed by connecting multiple round steels, so that materials can enter the suction pipe 111 from multiple openings.

[0060] In order to achieve precise adjustment of the height position of the suction gun assembly 11, in some embodiments of the present application, please refer to Figure 4 and Figure 6 The lifting assembly 12 includes a mounting plate 121 and a plurality of screw modules 122. The suction gun assembly 11 is arranged on the mounting plate 121. The plurality of screw modules 122 are evenly distributed along the circumference of the suction gun assembly 11. The mounting plate 121 is connected to the slides of the plurality of screw modules 122. The slides of the plurality of screw modules 122 are driven to move in the vertical direction by a plurality of servo motors, thereby realizing precise adjustment of the height position of the suction gun assembly 11.

[0061] Specifically, the mounting plate 121 is horizontally arranged, the suction gun assembly 11 is arranged through the middle of the mounting plate 121, the axis of the suction gun assembly 11 is vertically arranged to the mounting plate 121, and the suction gun assembly 11 is fixedly connected to the mounting plate 121 through a flange plate. When the mounting plate 121 is raised and lowered under the drive of multiple screw modules 122, the height position of the suction gun assembly 11 changes.

[0062] In some embodiments of the present application, the lifting assembly 12 also includes a fixing frame 123 for being fixedly connected to the mounting frame 3, a plurality of screw modules 122 are arranged on the fixing frame 123, the bag breaking mechanism 5 is fixedly arranged at the bottom of the fixing frame 123, and the suction gun assembly 11 can slide relative to the fixing frame 123, so that the suction gun assembly 11 can retract or extend out of the middle channel of the bag breaking mechanism 5.

[0063] In order to drive each mechanism to act according to the remaining material in the ton bag 7 during the material suction process, in some embodiments of the present application, please refer to Figure 1 and Figure 8 The suction device also includes a weighing mechanism 6 and a controller, and the weighing mechanism 6, the suction mechanism 1, the lifting mechanism 2 and the bag-beating mechanism 4 are all connected to the controller. When the weighing mechanism 6 detects that the weight of the material inside the ton bag 7 is small, the controller can send a command to the lifting mechanism 2 to lift the ton bag 7 or swing the ton bag 7 (swinging the ton bag 7 is achieved by lifting the ton bag 7 to different heights through each lifting component 21), so that the suction pipe 111 can absorb the material inside the ton bag 7; the controller can also send a command to the suction mechanism 1 to make the suction gun component 11 further descend under the action of the lifting component 12 to absorb the material inside the ton bag 7; the controller can also send a command to the bag-beating mechanism 4, so that the bag-beating mechanism 4 beats the ton bag 7 or drives the ton bag 7 to vibrate at high frequency through the vibration component 42, so that the material gathers to the middle of the ton bag 7, which is convenient for the suction gun component 11 to absorb.

[0064] In some embodiments of the present application, the weighing mechanism 6 includes a plurality of weighing sensors sequentially arranged along the circumference of the mounting frame 3 , which can achieve accurate weighing of the ton bag 7 .

[0065] After the suction is completed, in order to realize automatic bag throwing, in some embodiments of the present application, please refer to Figure 1 The lifting mechanism 2 further includes a plurality of automatic unhooking components 22, the lifting component 21 is connected to the automatic unhooking component 22, and the automatic unhooking component 22 includes a hook for hanging the ton bag 7. After the suction is completed, the hook is separated from the handle of the ton bag 7 by the automatic unhooking component 22, so that the bag is automatically thrown, which can reduce the labor intensity of the operator.

[0066] In some embodiments of the present application, the automatic unhooking assembly 22 further includes a driving cylinder connected to the hook, and the driving cylinder can rotate the hook, thereby causing the handle strap of the ton bag 7 to be unhooked from the hook.

[0067] In some embodiments of this application, please refer to Figures 1 to 8 The method of using the suction device of the present application is as follows:

[0068] Step 1: Move the ton bag 7 to the accommodation space of the mounting rack 3 by a transfer device such as an AGV trolley or a forklift;

[0069] Step 2: The operator connects the handle strap of the ton bag 7 to the hook in the automatic unhooking assembly 22;

[0070] Step 3: After the operator moves to the safe area, the dust removal component 52 is turned on, and the ton bag 7 is lifted at a uniform speed through multiple lifting components 21. The detection value of the weighing mechanism 6 gradually increases to a fixed value, which is the initial weight of the ton bag 7 and the material. The lifting component 21 continues to lift until the bag-breaking knife 511 is inserted into the ton bag 7, forming a suction gap at the top of the ton bag 7, and the dust on the top of the ton bag 7 and the debris of the ton bag 7 are collected by the dust removal component 52;

[0071] Step 4: The lifting component 21 lowers the ton bag 7 for a distance so that the ton bag 7 is below the bag breaking component 51, and the detection value of the weighing mechanism 6 is the initial weight of the ton bag 7 and the material; the suction gun component 11 is lowered by the lifting component 12, so that the suction pipe 111 enters the ton bag 7 from the suction gap, and the material inside the ton bag 7 is sucked through the suction pipe 111. During the suction process, the suction gun component 11 can be gradually lowered by the lifting component 12 so that the suction port 1112 is always in contact with the material; multiple lifting components 21 continuously adjust the height position of the ton bag 7 to shake the ton bag 7 to avoid the situation where material bridges appear inside the ton bag 7;

[0072] Step 5: When the value detected by the weighing mechanism 6 is 5% of the initial weight of the ton bag 7 and the material, the vibration assembly 42 is moved to contact the outer surface of the ton bag 7 through the swing arm assembly 41 in the bag-beating mechanism 4, and the ton bag 7 is driven to vibrate at high frequency by the high-frequency vibrator 421 in the vibration assembly 42, so that the material on the inner wall of the ton bag 7 is shaken off, and the material is vibrated to the middle of the ton bag 7, that is, the central area of ​​the suction pipe 111, so that the suction pipe 111 completes the absorption of the remaining material;

[0073] Step six: When the weighing mechanism 6 detects the weight of the ton bag 7, the suction gun assembly 11 is retracted through the lifting assembly 12, and the automatic unhooking assembly 22 removes the handle strap of the ton bag 7 from the hook. The ton bag 7 falls to the ground due to its own gravity and can be recovered manually.

[0074] The suction device provided in the present application can improve the degree of automation during material feeding, reduce the labor intensity of operators, simplify the feeding process of the ton bag 7, help reduce the material residue inside the ton bag 7, and help reduce dust leakage during the feeding process.
