Paper blank feeding mechanism

Abstract

This utility model belongs to the field of material feeding technology, specifically relating to a paper mold blank feeding mechanism. The paper mold blank feeding mechanism of this utility model, through the setting of a transfer transmission mechanism including a drive disk, a drive rod, a flipping guide structure, and a flipping drive arm, utilizes a drive device to drive the drive disk to rotate continuously and stably in the same direction. Through the transmission cooperation between the drive rod and the flipping guide structure, the suction cup assembly achieves periodic and continuous back-and-forth flipping motion between the material stacking channel outlet and the target placement position. This efficiently and stably separates and transfers the paper mold blanks stacked in the inclined channel one by one to the target workstation. It not only significantly reduces the labor intensity of manual piece-by-piece feeding and improves feeding efficiency and automation level, but also, relying on the continuous feeding action achieved by the drive disk rotating in a single direction, has a compact structure and a stable and reliable motion trajectory, which helps ensure the positioning accuracy of the paper mold blanks during the transfer process and the continuity of the overall production rhythm.

Description

Technical Field

[0001] This utility model belongs to the field of material feeding technology, specifically relating to a paper mold blank feeding mechanism. Background Technology

[0002] Paper mold preforms are a three-dimensional papermaking technology. Using waste paper as raw material, it shapes paper products into specific forms using special molds on a molding machine. The production process includes pulping, adsorption molding, drying, and setting, and is environmentally friendly and recyclable. Because foam lunch boxes contain components harmful to the environment and human health, the lunch box market largely uses paper mold preforms for production. Existing paper mold preform laminating or labeling equipment relies on manual loading of stacked lunch boxes one by one, resulting in high labor intensity and low automation. Utility Model Content

[0003] The purpose of this invention is to overcome the problems of high labor intensity and low automation level in the existing paper mold blank feeding, which is done manually, and to provide an automated feeding mechanism for paper mold blanks.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The paper mold blank feeding mechanism includes: The material storage mechanism includes a material storage rack and a material stacking channel arranged at an angle on the material storage rack for stacking paper mold blanks. The lower end of the material stacking channel is provided with a discharge port, and the front side of the material storage rack is provided with a material transfer area.

[0005] A transfer mechanism is located within the material transfer area and on one side of the material stacking channel's outlet. It is used to place the paper mold blanks from the storage mechanism one by one into the target position. The transfer mechanism includes a suction cup assembly for adsorbing the paper mold blanks from the storage mechanism and a transfer transmission mechanism. The transfer transmission mechanism includes a drive disk, a drive rod, a flipping guide structure, and a flipping drive arm. Both ends of the suction cup assembly are rotatably connected to the flipping guide structure. One end of the flipping drive arm is rotatably connected to the material storage rack, and the other end is fixedly connected to the suction cup assembly. The drive disk is rotatably fixed and its outer side is connected to the flipping guide structure via the drive rod, so that when the drive disk rotates in the same direction, the suction cup assembly periodically flips back and forth between the outlet and the target placement position to place the paper mold blanks from the storage mechanism into the target position for transport.

[0006] A drive unit is used to drive the drive disk to rotate relative to each other.

[0007] Compared with existing technologies, the paper mold blank feeding mechanism of this utility model, through the setting of a transfer transmission mechanism including a drive disk, a drive rod, a flipping guide structure, and a flipping drive arm, and the use of a drive device to drive the drive disk to rotate continuously and stably in the same direction, and through the transmission cooperation of the drive rod and the flipping guide structure, enables the suction cup assembly to achieve periodic and continuous back-and-forth flipping motion between the material stacking channel outlet and the target placement position, thereby efficiently and stably separating and transferring the paper mold blanks stacked in the inclined channel one by one to the target workstation. This not only significantly reduces the labor intensity of manual piece-by-piece feeding and improves the feeding efficiency and automation level, but also relies on the continuous feeding action achieved by the drive disk rotating continuously in one direction. The structure is compact and the motion trajectory is stable and reliable, which helps to ensure the positioning accuracy of the paper mold blanks during the transfer process and the continuity of the overall production rhythm.

[0008] Furthermore, the flipping guide structure includes a synchronizing rod and two sets of linkage frames. One linkage frame includes a first swing arm and a second swing arm connected at their ends and forming a certain angle. The other linkage frame includes a third swing arm. The suction cup assembly is rotatably connected to the outer ends of the second and third swing arms, respectively. The rotation center of the linkage frame is rotatably connected to the material storage rack. The rotation centers of the two linkage frames are synchronously linked by the synchronizing rod to achieve synchronous rotation of the two linkage frames. The end of the drive rod is rotatably connected to the outer end of the first swing arm. When the linkage frame drives the suction cup assembly to swing relative to each other, the flipping drive arm links the relative rotation of the suction cup assembly, so that the suction cup assembly picks up the paper mold blank at the discharge port and rotates to the lower side to release the paper mold blank to the target position. With this configuration, including the synchronizing rod and two sets of linkage frames... The flipping guide structure includes a linkage frame consisting of a first and a second swing arm at an angle, and a third swing arm. The suction cup assembly is rotatably connected to the outer ends of the second and third swing arms on both sides, respectively. The two linkage frames rotate synchronously through a synchronizing rod, and the drive rod is rotatably connected to the outer end of the first swing arm. This structure ensures the symmetry and stability of the linkage movement on both sides when the drive disc drives the linkage frame to swing through the drive rod. At the same time, the flipping drive arm pulls the suction cup assembly to rotate relative to each other during the swinging process, so that the suction cup assembly can smoothly flip to the target position and accurately release after picking up the paper mold blank at the discharge port. This not only enhances the coordination and reliability of the transfer process, but also effectively avoids the paper mold blank from shifting or falling off during the transfer, further improving the feeding accuracy and the continuity of equipment operation.

[0009] Furthermore, at least two material stacking channels are arranged in parallel, and the upper opening of the material stacking channel forms a material inlet; by arranging at least two material stacking channels in parallel, the synchronous storage and alternating feeding of various paper mold blanks are realized, which significantly improves the material supply efficiency and overall production efficiency of the equipment.

[0010] Furthermore, the suction cup assembly includes a rotating rod and several suction cup components arranged along the length of the rotating rod; at least three material stacking channels are arranged in parallel, and the number of suction cup components is set accordingly; by setting up at least three material stacking channels in parallel and correspondingly configuring suction cup assemblies, efficient synchronous feeding and parallel operation of multiple material channels are realized, which greatly improves the loading capacity and production cycle of the equipment.

[0011] Furthermore, the discharge port is provided with limiting baffles on at least two sides to prevent the paper mold blank from falling off; by setting up limiting baffles on at least two sides of the discharge port, the paper mold blank is effectively prevented from accidentally slipping or misaligning during the separation process or in the material stacking channel, thus ensuring the reliability and continuity of the feeding process.

[0012] Furthermore, the driving device includes a drive motor, a belt drive mechanism, and a drive shaft, wherein the drive motor is connected to the drive shaft via the belt drive mechanism. Attached Figure Description

[0018] See Figures 1 to 3The paper mold blank feeding mechanism of this utility model includes: The material storage mechanism 1 includes a material storage rack 11 and a material stacking channel 12 arranged on the material storage rack 11 for stacking paper mold blanks and arranged at an incline. The lower end of the material stacking channel 12 is provided with a discharge port 13, and the front side of the material storage rack 11 is provided with a material transfer area 14.

[0019] The transfer mechanism 2 is located within the material transfer area 14 and on one side of the discharge port 13 of the material stacking channel 12. It is used to place the paper mold blanks on the storage mechanism 1 one by one into the target position. The transfer mechanism 2 includes a suction cup assembly 29 for adsorbing the paper mold blanks on the storage mechanism 1 and a transfer transmission mechanism. The transfer transmission mechanism includes a drive disk 21, a drive rod 22, a flipping guide structure, and a flipping drive arm 24. The two ends of the suction cup assembly 29 are rotatably connected to the flipping guide structure. One end of the flipping drive arm 24 is rotatably connected to the material storage rack 11, and the other end of the flipping drive arm 24 is fixedly connected to the suction cup assembly 29. The drive disk 21 can be rotatably fixed and its outer side is connected to the flipping guide structure through the drive rod 22. When the drive disk 21 rotates in the same direction, the suction cup assembly 29 can perform periodic back-and-forth flipping work between the discharge port 13 and the target placement position to place the paper mold blanks on the storage mechanism 1 into the target position for transportation.

[0020] The drive device 3 is used to drive the drive disk 21 to rotate relative to each other.

[0021] Compared with the prior art, the paper mold blank feeding mechanism of this utility model, by setting up a transfer transmission mechanism including a drive disk 21, a drive rod 22, a flipping guide structure, and a flipping drive arm 24, and using a drive device 3 to drive the drive disk 21 to rotate continuously and stably in the same direction, and through the transmission cooperation between the drive rod 22 and the flipping guide structure, the suction cup assembly 29 realizes a periodic and continuous back-and-forth flipping motion between the material stacking channel 12 outlet 13 and the target placement position, thereby efficiently and stably separating and transferring the paper mold blanks stacked in the inclined channel one by one to the target work position. This not only significantly reduces the labor intensity of manual piece-by-piece feeding and improves the feeding efficiency and automation level, but also relies on the continuous feeding action achieved by the drive disk 21 rotating continuously in one direction. The structure is compact and the motion trajectory is stable and reliable, which helps to ensure the positioning accuracy of the paper mold blanks during the transfer process and the continuity of the overall production rhythm.

[0022] See Figures 1 to 3In one embodiment, the flipping guide structure includes a synchronizing rod 25 and two sets of linkage frames 26. One linkage frame 26 includes two first swing arms 261 and second swing arms 262 connected at their ends and forming a certain angle. The other linkage frame 26 includes a third swing arm 263. The suction cup assembly 29 is rotatably connected to the outer ends of the second swing arms 262 and the third swing arms 263 on both sides, respectively. The rotation center of the linkage frame 26 is rotatably connected to the material storage rack 11. The rotation centers of the two linkage frames 26 are synchronously linked by the synchronizing rod 25 to achieve synchronous rotation of the two linkage frames 26. The end of the drive rod 22 is rotatably connected to the outer end of the first swing arm 261. When the linkage frame 26 drives the suction cup assembly 29 to swing relative to each other, the flipping drive arm 24 links the suction cup assembly 29 to rotate relative to each other, so that the suction cup assembly 29 picks up the paper mold blank at the discharge port 13 and rotates to the lower side to release the paper mold blank to the target position. With this configuration, by including the synchronizing rod 25 and The flipping guide structure of the two sets of linkage frames 26 includes one linkage frame 26 consisting of a first swing arm 261 and a second swing arm 262 at an angle, and the other linkage frame 26 consisting of a third swing arm 263. The suction cup assembly 29 is rotatably connected to the outer ends of the second swing arm 262 and the third swing arm 263 on both sides respectively. The two linkage frames 26 rotate synchronously through the synchronizing rod 25, and the driving rod 22 is rotatably connected to the outer end of the first swing arm 261. This structure allows the driving disc 21 to drive the linkage frame 26 to swing through the driving rod 22, while relying on the synchronizing rod 25 to ensure the symmetry and stability of the linkage movement on both sides. At the same time, the flipping driving arm 24 pulls the suction cup assembly 29 to rotate relative to each other during the swinging process, thereby enabling the suction cup assembly 29 to smoothly flip to the target position and accurately release after picking up the paper mold blank at the discharge port 13. This not only enhances the coordination and reliability of the transfer process, but also effectively avoids the paper mold blank from shifting or falling off during the transfer, further improving the feeding accuracy and the continuity of equipment operation.
