For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0031] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] Referring to Figure 1 As shown, in some embodiments of the present utility model, a grasping and feeding device 3 is provided, including: a guide rail 31, a sliding and vibrating assembly 32, and a jaw assembly 33; one end of the sliding and vibrating assembly 32 is in driving connection with the guide rail 31; one end of the jaw assembly 33 is fixedly connected to the sliding and vibrating assembly 32, and a jaw member 331 adapted to grasp a material package is provided at the other end of the jaw assembly 33; the sliding and vibrating assembly 32 has a vibrating state of reciprocating motion in the vertical direction and a conveying state of sliding motion along the length direction of the guide rail 31; in the conveying state, the sliding and vibrating assembly 32 drives the jaw assembly 33 to slide to the blanking position, and in the vibrating state, the sliding and vibrating assembly 32 drives the jaw assembly 33 to reciprocate in the vertical direction to shake off the materials in the material package.

[0033] Specifically, the jaw assembly 33 is connected to the guide rail 31 through the sliding and vibrating assembly 32. The sliding and vibrating assembly 32 is slidably disposed on the guide rail 31. The jaw assembly 33 is provided with a jaw member 331 adapted to grasp a material package. The jaw member 331 clamps the material package. In the conveying state, the sliding and vibrating assembly 32 drives the jaw assembly 33 to slide to the blanking position. After the blanking is completed, the sliding and vibrating assembly 32 drives the jaw assembly 33 to reciprocate in the vertical direction to shake off the materials in the material package, so as to completely unload the materials in the material package. The grasping and feeding device 3 realizes the transportation and shaking of the material package, thereby improving the unloading efficiency and ensuring complete unloading.

[0034] It can be understood that in the conveying state and the vibrating state, the jaw member 331 always remains in a clamped state to be adapted to grasp and fix the material package, so as to avoid the material package falling off during the vibration process and affecting the blanking. A synchronous belt and a moving drag chain are provided on the guide rail 31 to drive the sliding of the sliding and vibrating assembly 32. The length direction of the guide rail 31 is consistent with the conveying direction of the material package.

[0035] In some embodiments of the present utility model, the sliding vibration assembly 32 includes: a first mounting plate 321, a second mounting plate 322, an elastic member 323, and a first driving member 324; the first mounting plate 321 is slidably connected to the guide rail 31, the second mounting plate 322 and the first mounting plate 321 are connected by the elastic member 323, the output end of the first driving member 324 is drivingly connected to the second mounting plate 322, and the first driving member 324 and the elastic member 323 drive the second mounting plate 322 to reciprocate in the vertical direction.

[0036] Specifically, the first mounting plate 321 is slidably connected to the guide rail 31, the second mounting plate 322 is connected to the first mounting plate 321 by the elastic member 323, the first driving member 324 is a hydraulic driving device. When grasping the material package, the first driving member 324 drives the second mounting plate 322 to move away from the first mounting plate 321, and the elastic member 323 is stretched under the action of the tensile force. Subsequently, the first mounting plate 321 slides along the length direction of the guide rail 31, thereby driving the material package to move to the discharging position. During the discharging process, the first driving member 324 and the elastic member 323 interact to drive the second mounting plate to reciprocate vertically, so as to shake the material package, facilitate the shaking off of the materials in the material package, improve the discharging efficiency, and ensure complete discharging at the same time.

[0037] It can be understood that the first driving member 324 provides an instantaneous force to the second mounting plate 322. Subsequently, under the action of the elastic force of the elastic member 323 and the gravity of the material package, the second mounting plate 322 reciprocates in the vertical direction. The instantaneous force refers to the force acting on an object instantaneously, that is, the force acting on an object within a very short time.

[0038] In some embodiments of the present utility model, the jaw assembly 33 includes a fixed frame 333 fixedly connected to the second mounting plate 322, and a second driving member 332 provided on the fixed frame 333. The jaw member 331 is provided on the fixed frame 333 and is drivingly connected to the output end of the second driving member 332. The second driving member 332 drives the jaw member 331 to clamp or release.

[0039] Specifically, the second driving member 332 and the jaw member 331 are mounted on the fixed frame 333, and the second driving member 332 drives the jaw member 331 to clamp or release. A visual detection module and a positioning detection module are provided on the fixed frame 333. When the positioning detection module detects that the grasping and feeding device 3 reaches the specified material taking position, the visual detection module detects the position of the material package and feeds back the position of the material package to the controller. The controller controls the second driving member 332 to drive the jaws to grasp the material.

[0040] Refer to Figure 2 and Figure 3As shown in the figure, the present utility model also provides an unpacking device, which includes: a frame 1, a feeding device 2, a discharging device 4, a grasping and feeding device 3, and a cutting device 5; the feeding device 2 is arranged at one end of the frame 1 to be suitable for conveying material packages; the discharging device 4 is arranged at the other end of the frame 1 to be suitable for collecting the materials in the material packages; the grasping and feeding device 3 is arranged inside the frame 1 and is located between the feeding device 2 and the discharging device 4, and the grasping and feeding device 3 is suitable for grasping the material packages from the feeding device 2 and conveying them above the discharging device 4; the cutting device 5 is arranged inside the frame 1 and is located above the discharging device 4, and the cutting device 5 includes a rotary cutter 51, and the rotary cutter 51 is suitable for cutting open the material packages so that the materials fall into the discharging device 4.

[0041] Specifically, after the material packages enter the frame 1, they are transported by the feeding device 2, the grasping and feeding device 3 clamps the material packages, and transports them above the discharging device 4. The rotary cutter 51 of the cutting device 5 cuts open the material packages so that the materials fall into the discharging device 4. During the discharging process, the sliding vibration assembly 32 of the grasping and feeding device 3 drives the jaw assembly 33 to reciprocate vertically to shake off the materials in the material packages, thereby ensuring that the materials are completely unloaded from the material packages and improving the discharging efficiency.

[0042] It can be understood that the frame 1 is integrally formed, reducing the problems of loosening and dropping caused by bolt connection and reducing the maintenance frequency of the equipment; the flip operation windows provided on both sides of the frame 1 facilitate the installation, maintenance and repair of the equipment, and at the same time, the abnormal conditions during the operation of the equipment can be clearly monitored. An overhead human-machine interface operation display screen is provided outside the frame 1 to increase the operability of the equipment and monitor the remote transmission of the operation process throughout the whole process.

[0043] Refer to Figure 4 As shown in the figure, in some embodiments of the present utility model, the feeding device 2 includes a roller track 21 arranged inside the frame 1 and a pressing component 22 arranged above the roller track 21. The pressing component 22 is fixedly arranged on the roller track 21, and the material packages move along the conveying direction of the roller track 21 and are pressed and regularized by the pressing component 22.

[0044] Specifically, the rollers of the roller track 21 are in the shape of squares to perform the bag jolting treatment on the material packages. The pressing component 22 slides along with the materials on the roller track 21, and the pressing component 22 presses the material packages on the roller track 21 to prevent the material packages from falling off the roller track 21 and affecting the feeding efficiency. In addition, the method of upper pressing and lower jolting is adopted to shape the material packages, which is convenient for subsequent grasping and discharging.

[0045] It can be understood that a guiding flared opening is provided at the inlet of the roller track 21 to enable the material packages to smoothly enter the roller track 21 and prevent the material packages from shifting and affecting the feeding efficiency.

[0046] Refer to Figure 5As shown, in some embodiments of the present utility model, a first purging device 8 is provided at the feeding end of the feeding device 2. The first purging device 8 is arranged on the frame 1, and the material package enters the roller path 21 after passing through the first purging device 8. The first purging device 8 is adapted to remove the waste on the surface of the material package.

[0047] The material pressing assembly 22 includes a second purging device 222 and a material pressing roller 221 which are arranged at intervals along the length direction of the roller path 21. The material pressing roller 221 has a cylindrical structure and is adapted to roll on the upper surface of the material package. The second purging device 222 is adapted to blow off and remove the waste on the surface of the material package.

[0048] Specifically, there is dust and waste on the surface of the material package. To ensure the production quality, it is necessary to remove the dust and waste on the surface of the material package. A first purging device 8 is provided at the feeding end of the feeding device 2. The first purging device 8 includes an upper purging part and a lower purging part which are respectively arranged on the upper and lower sides of the roller path 21. The first purging device 8 blows off the dust and waste on the upper and lower surfaces of the material package to ensure the subsequent production quality.

[0049] It can be understood that during the conveying process of the material package on the roller path 21, during the upper pressing of the material pressing assembly 22 and the lower jolting of the roller path 21, some materials are likely to be exposed from the gaps of the material package to form waste. To avoid the influence of this part of the waste on the subsequent production, a second purging device 222 is provided on the material pressing assembly 22. When the material pressing assembly 22 rolls on the upper surface of the material package, the second purging device 222 is adapted to blow off the waste on the surface of the material package to ensure the subsequent production quality.

[0051] Specifically, a negative pressure is formed in the inner cavity of the frame 1. A dust removal cover 71 is provided on the top of the frame 1. The top of the dust removal cover 71 is connected to the dust collection pipe 72. The dust removal cover 71 is covered on the top of the frame 1 and is communicated with the inner cavity of the frame 1, so as to collect the dust and waste in the inner cavity of the frame 1, effectively avoiding the waste from entering the feeding device 4 and affecting the subsequent production quality, and at the same time avoiding the dust pollution of the environment and affecting the physical health of the staff.

[0052] In some embodiments of the present utility model, the feeding device 4 includes a collecting hopper and a vibrator. The collecting hopper is arranged at the bottom of the frame 1 and is located below the cutting device 5. The vibrator is arranged on the side wall of the collecting hopper. The vibrator is adapted to knock on the collecting hopper to disperse the materials.

[0053] Specifically, the aggregate hopper is arranged at the bottom of the frame 1 for collecting materials. A vibrator is provided on the side wall of the aggregate hopper. Through the knocking of the vibrator, it is possible to prevent the materials from forming lumps in the aggregate hopper, which may affect the collection of materials.

The output end of the fourth driving member 63 is in transmission connection with the spiral member 62 to drive the spiral member 62 to rotate. The waste hopper 61 is communicated with the waste box 64. The grasping and feeding device 3 slides to the upper part of the waste collection device 6 to be suitable for throwing the waste bag packaging into the waste hopper 61. The spiral member 62 rotates to convey the waste bag packaging spirally into the waste box 64.

[0057] Specifically, after the feeding is completed, the grasping and feeding device 3 transports the waste bag packaging to the upper part of the waste collection device 6. The second driving member 332 drives the jaw member 331 to loosen, so as to throw the waste bag packaging into the waste hopper 61 of the waste collection device 6. The fourth driving member 63 drives the spiral member 62 to rotate to stir the waste bag packaging spirally and convey it into the waste box 64. After being stirred by the spiral member 62, the waste bag packaging is twisted into a ball to reduce the occupied floor area, thereby increasing the accommodation rate of the waste box 64. The waste bag packaging can be recycled to reduce the cost.
