[0036] Please refer to Figures 1-9 , a double-station corrugated board production folding device is shown, which comprises a frame 1, two folding assemblies 2 and a moving assembly 3 are arranged on the frame 1.

[0037] The two folding assemblies 2 are symmetrically arranged on the frame 1, and one of the folding assemblies 2 is connected with the moving assembly 3, and the moving assembly 3 can control the folding assembly 2 connected therewith to move on the frame 1.

[0038] The moving assembly 3 comprises a secondary sprocket shaft 301, a primary sprocket shaft 302 and a crank 303. The secondary sprocket shaft 301 is provided with two secondary sprockets 304 respectively arranged on the two side edges of the frame 1. Each secondary sprocket 304 is connected to the corresponding secondary sprocket shaft 301 through a bearing. The primary sprocket shaft 302 is provided with two primary sprockets 305 fixedly connected to the primary sprocket shaft 302. The primary sprocket shaft 302 is connected to the two side edges of the frame 1 through a bearing. The primary sprockets 305 are connected to the corresponding secondary sprockets 304 through a chain 306. The chain 306 is connected to the folding assembly 2 away from the crank 303. One end of the crank 303 is fixedly connected to one end of the primary sprocket shaft 302. The chain 306 is provided with a connecting steel plate 307 fixedly connected to the lower end surface of the chain 306.

[0039] When the operator rotates the crank 303, the crank 303 drives the primary sprocket shaft 302 to rotate around its axis. Since the primary sprockets 305 are fixedly connected to the primary sprocket shaft 302, the primary sprockets 305 rotate synchronously with the primary sprocket shaft 302. The rotation of the primary sprockets 305 is transmitted to the secondary sprockets 304 through the chain 306, so that the secondary sprockets 304 rotate around the secondary sprocket shaft 301. Since the connecting steel plate 307 on the chain 306 is fixedly connected to the folding assembly 2 away from the crank 303, the connecting steel plate 307 drives the folding assembly 2 to move on the frame 1 along a predetermined direction under the transmission of the chain 306, so as to adjust the distance between the two folding assemblies 2 to adapt to corrugated boards of different sizes.

[0040] The folding assembly 2 comprises a folding bottom frame one 201, a folding bottom frame two 202, an intermediate plate 203, a cylinder connecting seat 204, a driving cylinder 205, a connecting piece 206, a connecting rod 207 and a connecting angle iron 208. The connecting angle iron 208 is provided with two connecting angle irons respectively fixedly arranged on the lower end surfaces of the folding bottom frame one 201 and the folding bottom frame two 202. The adjacent two side edges of the folding bottom frame one 201 and the folding bottom frame two 202 are connected to the two sides of the intermediate plate 203 through hinges. The cylinder connecting seat 204 is fixedly arranged on the middle part of the intermediate plate 203 and connected to the bottom of the driving cylinder 205. The connecting piece 206 is fixedly connected to the telescopic rod of the driving cylinder 205. The connecting rod 207 is provided with two connecting rods. One end of one connecting rod 207 is connected to one side of the connecting piece 206 through a rod end joint bearing, and the other end is connected to the connecting angle iron 208 arranged on the lower end surface of the folding bottom frame one 201 through a rod end joint bearing. One end of the other connecting rod 207 is connected to the other side of the connecting piece 206 through a rod end joint bearing, and the other end is connected to the connecting angle iron 208 on the folding bottom frame two 202 through a rod end joint bearing.

[0041] When the driving cylinder 205 receives the working instruction, the telescopic rod starts telescopic movement. The telescopic movement of the telescopic rod drives the connecting piece 206 to move linearly along the telescopic direction. Since the two ends of the connecting rod 207 are connected with the connecting piece 206 and the connecting angle iron 208 through the rod end joint bearing respectively, the movement of the connecting piece 206 drives the connecting angle iron 208 to be pushed or pulled through the connecting rod 207. The connecting angle iron 208 is fixed on the lower end surface of the folding bottom frame one 201 and the folding bottom frame two 202 respectively, and the folding bottom frame one 201 and the folding bottom frame two 202 are connected with the middle plate 203 through the hinge. Thus, under the action of the connecting rod 207, the folding bottom frame one 201 and the folding bottom frame two 202 rotate relative to the middle plate 203 around the hinge, so as to realize the folding action of the corrugated board placed on the folding bottom frame one 201 and the folding bottom frame two 202.

[0042] The folding bottom frame one 201 and the folding bottom frame two 202 have the same structure, both of which are hollow inside. The upper end surface of the folding bottom frame one 201 and the folding bottom frame two 202 is provided with the suction hole 209, and the lower end surface of the folding bottom frame one 201 and the folding bottom frame two 202 is provided with the connecting pipe 210. The suction hole 209 penetrates the upper end surface of the folding bottom frame one 201 and the folding bottom frame two 202. One end of the connecting pipe 210 on the folding bottom frame one 201 is connected with the internal cavity, and the other end is connected with the external air extractor. One end of the connecting pipe 210 on the folding bottom frame two 202 is connected with the internal cavity, and the other end is connected with the external air extractor.

[0043] Before the folding operation, the air extractor is started. When the air extractor works, the air enters the internal cavity of the folding bottom frame one 201 and the folding bottom frame two 202 from the connecting pipe 210, and then is discharged through the suction hole 209, so as to form negative pressure at the suction hole 209. When the corrugated board is placed on the folding bottom frame one 201 and the folding bottom frame two 202, the negative pressure tightly adsorbs the corrugated board on the upper end surface of the folding bottom frame, so as to ensure that the corrugated board does not displace during the folding process, and ensure the accuracy and stability of the folding.

[0044] The folding bottom frame two 202 close to the handle 303 is fixedly connected with the upper end surface of the rack 1, as a fixed station. The lower end surface of the folding bottom frame two 202 away from the handle 303 is fixedly connected with the upper end surface of the connecting steel plate 307, as a movable station, which can be adjusted in position through the moving assembly 3.

[0045] Further, the upper end surface of the folding bottom frame one 201 is provided with a plurality of suction holes 209, and the suction holes 209 are uniformly arranged on the folding bottom frame one 201, so as to ensure that the suction force on the corrugated board is uniformly distributed, and better fix the paper board.

[0046] Further, the upper end face of the folded bottom frame two 202 is provided with a plurality of adsorption holes 209, and the adsorption holes 209 are uniformly arranged on the folded bottom frame two 202. Similarly, the fixing effect on the corrugated board is improved.

[0047] Further, the cylinder body of the driving cylinder 205 is further provided with a reinforcing block 211, and the connecting piece 206 is further provided with a guide rod 212, one end of the guide rod 212 is fixedly connected with the connecting piece 206, and the rod body of the guide rod 212 is connected with the reinforcing block 211 through a sliding sleeve.

[0048] When the telescopic rod of the driving cylinder 205 drives the connecting piece 206 to move, the guide rod 212 moves with the connecting piece 206. Since the rod body of the guide rod 212 is connected with the reinforcing block 211 through the sliding sleeve, the sliding sleeve can slide along the rod body of the guide rod 212, and the reinforcing block 211 is fixed on the cylinder body of the driving cylinder 205. Thus, the cooperation of the guide rod 212 and the reinforcing block 211 can limit the movement direction of the connecting piece 206, so that it can only move in the predetermined straight line direction, thereby enhancing the stability of the driving cylinder 205, ensuring the stability of the movement of the connecting piece 206, reducing the failure rate of the equipment during operation, and prolonging the service life of the equipment.

[0049] Working principle:

[0050] I. Two workstations simultaneously fold two corrugated boards

[0051] The worker places the corrugated board to be folded on the two folding assemblies 2, starts the air extractor, air enters the internal cavity of the folding bottom frame from the connecting pipe 210, and is discharged from the adsorption holes 209, forming negative pressure at the adsorption holes 209, and then tightly adsorbing the corrugated board on the upper end face of the folding bottom frame, preventing displacement of the paperboard during folding.

[0052] The driving cylinders 205 of the two folding assemblies 2 are started at the same time. The telescopic rod of the driving cylinder 205 starts to telescope, and the telescopic rod drives the connecting piece 206 to move linearly along its telescopic direction. Since the two ends of the connecting rod 207 are connected with the connecting piece 206 and the connecting angle iron 208 through the rod end joint bearing respectively, the movement of the connecting piece 206 will push or pull the connecting angle iron 208 through the connecting rod 207. The connecting angle iron 208 is fixed on the lower end face of the folding bottom frame one 201 and the folding bottom frame two 202 respectively, and the folding bottom frame one 201 and the folding bottom frame two 202 are connected with the middle plate 203 through a hinge. Thus, under the action of the connecting rod 207, the folding bottom frame one 201 and the folding bottom frame two 202 of the two folding assemblies 2 will rotate relative to the middle plate 203 around the hinge, and fold the respective corrugated board according to the predetermined folding angle and mode, realizing the simultaneous folding of two corrugated boards, and greatly improving the production efficiency.

[0053] After folding, turn off the drive cylinder 205 and the exhaust fan. The negative pressure at the suction hole 209 disappears, and the operator can easily remove the two folded corrugated cardboard pieces from the folding bottom frame, then prepare for the next round of folding.

[0054] 2. Two workstations work together to fold the same corrugated cardboard.

[0055] Preparation stage

[0056] Adjust the spacing between the two folding components 2 by turning the crank 303 so that they can better fold the cardboard.

[0057] Place one end of the corrugated cardboard on one of the folding components 2 and the other end on the other folding component 2. Turn on the exhaust fan so that both ends of the corrugated cardboard are attracted to the two folding components 2.

[0058] Simultaneously, the drive cylinders 205 of the two folding components 2 are activated, and the drive cylinders 205 drive the connecting piece 206 to move, so that the folding bottom frame 1 201 and the folding bottom frame 202 are folded through the connecting rod 207.

[0059] After completing all folding operations, turn off the drive cylinder 205 and the exhaust fan, remove the folded corrugated cardboard, and prepare for the next work cycle.

[0060] This dual-station design allows for the simultaneous and efficient folding of two corrugated cardboards, improving production efficiency. Furthermore, the flexible coordination between the two stations can meet the folding requirements of complex folding processes and high-precision corrugated cardboard, greatly enhancing the equipment's practicality and adaptability, and enabling it to better handle diverse corrugated cardboard production tasks.
