Description

Technical Field

[0001] The utility model relates to the field of suction and conveying mechanisms, in particular to a prefabricated bag suction and conveying mechanism. Background Technique

[0002] For the traditional separation and conveying of prefabricated bags, after a stack of prefabricated bags is laid flat, they are then separated one by one through a paging mechanism and conveyed to a designated position, and then transferred to the next process by a clamping jaw. In this conveying and feeding process, it is necessary for workers to smooth the prefabricated bags. The paging mechanism is prone to separating multiple sheets, with low speed and slow efficiency, especially when the thickness of the whole bag is uneven.

[0003] For example, the Chinese patent with the publication number CN218086290U discloses a bag supply and bag opening mechanism, which relates to the field of automation equipment. The key points of its technical solution are: including a material taking device and a bag opening device. The material taking device includes a feeding base fixed on the frame, a vertical rod fixed on the feeding base, a bag supply carrier longitudinally slidably connected to the vertical rod, a first linear module fixed on the feeding base for driving the longitudinal lifting of the bag supply carrier, and a YZ-axis linear module arranged on the frame and capable of shuttling between the bag supply carrier and the bag opening device. The output end of the YZ-axis linear module is fixedly connected with a bag taking suction cup, and a bag taking suction nozzle is arranged on the bag taking suction cup. The bag opening device includes a support mold and an opening suction nozzle arranged on the frame, and the frame is also provided with a second linear module for driving the support mold to extend into or withdraw from the packaging bag along the opening direction of the packaging bag. The utility model realizes the automatic bag taking and bag opening of the packaging bag, reduces the input of manual labor, and is beneficial to improving work efficiency.

[0004] To sum up, there are many drawbacks in the existing suction and conveying of prefabricated bags, which are summarized as follows:

[0005] ① The paging device for clamping and transferring prefabricated bags by the clamping jaw has high requirements for the flatness of the bag body. If the worker does not smooth the prefabricated bag, when the thickness of the whole bag is uneven, it may occur that multiple sheets are separated.

[0006] ② And the traditional paging mechanism has low speed and slow efficiency. Content of the Utility Model

[0007] In view of the deficiencies of the prior art, the utility model provides a prefabricated bag suction and conveying mechanism to solve the above problems.

[0008] To achieve the above purposes, the utility model is realized through the following technical solutions.

[0009] A prefabricated bag suction and conveying mechanism includes a displacement suction device, a conveying device, and a main body frame. The displacement suction device is connected to the main body frame, and the conveying device is connected to the main body frame. The displacement suction device includes a suction arm and a displacement transmission component. The displacement transmission component is used to control the up and down movement of the suction arm. The bottom of the suction arm is provided with suction ports in an array. The conveying device includes a conveying drive component and a negative pressure conveyor belt. The conveying drive component is used to drive the negative pressure conveyor belt. The negative pressure conveyor belt is internally provided with a negative pressure suction device. Since the adsorption is carried out in a single-sheet cycle, the prefabricated bags can be added in stacks in the early stage. Without manual intervention, single prefabricated bags can be stably conveyed to the next process, and the requirement for the flatness of the bag body is relatively low. Even if the prefabricated bags are not smoothed by hand or the thickness of the whole bag is uneven, the action of the suction arm pressing down and adsorbing can also adsorb them. Compared with the traditional page separation mechanism, it has a faster speed and higher efficiency.

[0010] Preferably, the displacement transmission component includes a lead screw transmission part and a guide rail slider part. The lead screw transmission part is fixed in the middle of the main body frame. The movable flange arranged on the lead screw transmission part is connected to the suction arm.

[0014] Preferably, an air nozzle is arranged on the suction arm, and negative pressure air supply is provided to the suction arm through the air nozzle.

[0016] Compared with the prior art, the present invention discloses a prefabricated bag suction and conveying mechanism, including a displacement suction device, a conveying device, and a main body frame. The three are combined and used to play a role. Since the adsorption is carried out in a single-sheet cycle, the prefabricated bags can be added in stacks in the early stage. Without manual intervention, single prefabricated bags can be stably conveyed to the next process, and the requirement for the flatness of the bag body is relatively low.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] A prefabricated bag suction and transmission mechanism includes a displacement suction device 1, a transmission device 2, and a main body frame 3. The displacement suction device 1 is connected to the main body frame 3, the transmission device 2 is connected to the main body frame 3. The displacement suction device 1 includes a suction arm 11 and a displacement transmission component 12. The displacement transmission component 12 is used to control the up and down movement of the suction arm 11. The bottom of the suction arm 11 is provided with a suction port 111 in an array. The transmission device 2 includes a transmission drive component 21 and a negative pressure conveyor belt 22. The transmission drive component 21 is used to drive the negative pressure conveyor belt 22. The negative pressure conveyor belt 22 is internally provided with a negative pressure suction device 23. The displacement transmission component 12 includes a lead screw transmission member 121 and a guide rail slider member 122. The lead screw transmission member 121 is fixed in the middle of the main body frame 3. The movable flange provided on the lead screw transmission member 121 is connected to the suction arm 11. The guide rail slider member 122 is fixed on both sides of the main body frame 3. The slider provided on the guide rail slider member 122 is connected to the suction arm 11. The transmission drive component 21 is arranged on the main body frame 3. The transmission drive component 21 is relatively common in the prior art, with a separate motor design or a combination of various conduction drives. Therefore, there are no special requirements for the structure, as long as it can meet the requirement of driving the negative pressure conveyor belt 22 to work. The negative pressure conveyor belt 22 is provided with a plurality of negative pressure adsorption grooves 221. The suction position of the negative pressure suction device 23 is aligned with the negative pressure adsorption grooves 221. The suction arm 11 is provided with a nozzle 112. The main body frame 3 is also provided with a guiding structure 31 corresponding to the negative pressure conveyor belt 22.

[0025] Working mode: Manually place the whole stack of prefabricated bags on the prefabricated bag storage conveyor belt. When the suction position detects the presence of bags, the prefabricated bag suction and transfer mechanism starts to work. The suction arm 11 is displaced by the lead screw drive 121, and its movement trajectory is restricted by the guide rail slider 122. When reaching the surface of the prefabricated bag, the suction port 111 under the suction arm 11 performs suction. Then, the motor of the lead screw drive 121 reaches the set torque and reversely lifts. During this process, the suction port 111 of the suction arm 11 always maintains negative pressure to suck up the prefabricated bag. When the suction arm 11 reaches the highest position and corresponds to the bottom of the negative pressure conveyor belt 22, the prefabricated bag is transferred to the negative pressure conveyor belt 22. The suction force of the negative pressure suction device 23 is transmitted to the prefabricated bag through the negative pressure suction groove 221, and then conveyed to the next process through the negative pressure conveyor belt 22. The guiding structure 31 can finely adjust and correct the conveying position of the prefabricated bag.
