Description

Technical Field

[0001] This application relates to the technical field of cardboard production equipment, and particularly to a board conveying mechanism. Background Art

[0002] During the production process of cardboard, pallets are required to carry stacked cardboard. After pushing the cardboard on the pallets to the paper laminating machine, the pallets are conveyed to the discharging end of the paper laminating machine through a pallet conveying line to receive the processed cardboard. The pallet conveying line is generally conveyed through guide rollers. In related technologies, there is a risk of slipping between the guide rollers and the pallets when conveying the pallets through the guide rollers, resulting in the deviation of the pallet posture. In order to ensure the accurate position of the pallet to ensure that the cardboard of the paper laminating machine can be better conveyed to the pallet, therefore, a pushing plate mechanism needs to be configured to stably convey the pallet on the guide roller to the next station. The existing pushing plate mechanism in the prior art includes a push claw for pushing the pallet, and at least two driving parts are required. One driving part drives the push claw to move along the conveying direction to push the pallet on the guide roller, and the other driving part drives the push claw to leave above the guide roller to avoid the subsequent entering pallets. The structure is relatively complex and the production cost is relatively high. Summary of the Utility Model

[0031] Referring to Figure 1 、 Figure 2 and Figure 4 According to the embodiment of the present application, the board feeding mechanism includes: a conveying module 100 and a pushing board module 200.

[0032] The conveying module 100 includes two and is used to convey the pallet along the front.

[0033] The push plate module 200 is located between two conveying modules 100; the push plate module 200 includes a push plate driving assembly 210, a base 220, and a swing block 230. The push plate driving assembly 210 is drivingly connected to the base 220 and is used to move the base 220 in the front-rear direction. The swing block 230 is rotatably arranged on the base 220. The upper end of the swing block 230 is higher than the conveying surface of the conveying module 100, and a counterweight portion 231 is arranged at the lower end of the swing block 230; a limiting portion 221 is arranged in front of the swing block 230 on the base 220, and the limiting portion 221 is located on the rotation path of the counterweight portion 231.

[0034] It can be understood that the left and right ends of the pallet are supported by the conveying module 100 and conveyed by the conveying module 100, while the middle part of the pallet corresponds to the push plate module 200. Specifically, the rear end of the plate conveying mechanism is docked with the first conveying line, and the front end of the plate conveying mechanism is docked with the second conveying line. Among them, the second conveying line can be docked with the blanking end of the paper pasting machine. In the initial state, the base 220 is located at the rear end of the plate conveying mechanism. Since the counterweight portion 231 is arranged at the lower end of the swing block 230, the weight of the lower end of the swing block 230 is much greater than that of the upper end of the swing block 230. Thus, the swing block 230 remains in a vertical state under the action of the gravity of the counterweight portion 231 at its lower end. When the first conveying line conveys the pallet into the plate conveying mechanism, the left and right ends of the pallet are supported by the conveying module 100, and the middle part of the pallet pushes the swing block 230. Since the swing block 230 is rotatably connected to the base 220, the swing block 230 can rotate relative to the base 220, causing the upper end of the swing block 230 to lower to allow the pallet to pass above the swing block 230 until the pallet completely passes above the swing block 230. The swing block 230 re-remains in a vertical state under the action of the gravity of the counterweight portion 231. At this time, the pallet is located in front of the swing block 230. Subsequently, the push plate driving assembly 210 drives the base 220 to move forward to drive the swing block 230 to push the rear end of the pallet. Since the limiting portion 221 is arranged in front of the swing block 230 and the limiting portion 221 is located on the rotation path of the counterweight portion 231, thus, after the swing block 230 contacts the rear end of the pallet, after the swing block 230 swings a certain angle, the counterweight will abut against the limiting portion 221, thereby restricting the swing of the swing block 230. Therefore, when the push plate driving assembly 210 drives the base 220 to continue moving forward, the upper end of the swing block 230 will push the pallet forward for conveying until the swing block 230 moves to the front end of the plate conveying mechanism to convey the pallet onto the second conveying line.

[0035] It can be understood that the push plate module 200 cooperates with the conveying module 100 to realize the stable conveying of the pallet, so as to ensure the posture of the pallet during the conveying process, avoid the deviation of the pallet during the conveying process, so as to ensure that the pallet can better receive the cardboard from the paper pasting machine, and can reduce the risk of collision between the pallet and other structures caused by the deviation of the pallet.

[0036] It can be understood that the swing block 230 is rotatably arranged on the base 220 and, by cooperating with the counterweight portion 231, can avoid the pallet and achieve automatic reset. When the push plate driving assembly 210 drives the base 220 to move forward, the swing block 230 can cooperate with the limiting portion 221 to limit the swing of the swing block 230, so as to ensure that the swing block 230 can push the pallet. Thus, the present application only needs to set a push plate driving assembly 210 to drive the swing block 230 to move back and forth. The avoidance and abutment of the pallet are achieved through the counterweight portion 231 and the limiting portion 221. The structure is simple, the use of driving parts is saved, and the production cost is reduced.

[0037] Refer to Figure 4 , according to some embodiments of the present application, the base 220 is provided with a guiding surface 2231, which slopes downward in the direction from front to back, and the swing block 230 is arranged at the front end of the base 220.

[0038] It can be understood that the lower end of the pallet is provided with a mating surface that slidably cooperates with the guiding surface 2231. Through the sliding cooperation of the guiding surface 2231 and the mating surface, a guiding effect can be achieved on the pallet when the pallet passes above the base 220, so that the position of the pallet is accurate after entering the plate conveying mechanism.

[0039] Specifically, the base 220 can correspond to the through groove at the bottom of the pallet, and the side surface of the base 220 cooperates with the through groove to guide the pallet.

[0040] Refer to Figure 4 , according to some embodiments of the present application, a weight reduction groove 232 is provided at the upper end of the swing block 230.

[0041] It can be understood that by providing the weight reduction groove 232 at the upper end of the swing block 230, the weight of the upper end of the swing block 230 can be further reduced, and the production cost of the swing block 230 can be saved.

[0042] Refer to Figure 4 , according to some embodiments of the present application, the length of the upper end of the swing block 230 is greater than the length of the lower end of the swing block 230.

[0043] It can be understood that the upper end of the swing block 230 is set to be longer to ensure that the upper end of the swing block 230 has sufficient contact area with the pallet, so as to improve the stability of the push plate. Moreover, the lower end of the swing block 230 is set to be shorter to reduce the occupied space of the counterweight portion 231.

[0044] Refer to Figure 4, according to some embodiments of the present application, the base 220 includes a bottom plate 222, a rotating member 224, and two connecting plates 223. The two connecting plates 223 are spaced apart and disposed at the upper end of the bottom plate 222. The bottom plate 222 is provided with an avoidance groove 2221 corresponding to the space between the two connecting plates 223. Both ends of the rotating member 224 are fixedly connected to the connecting plates 223. The swing block 230 is rotatably disposed on the rotating member 224 and is correspondingly located between the two connecting plates 223. The lower end of the swing block 230 passes through the avoidance groove 2221.

[0045] It can be understood that the swing block 230 can swing relative to the rotating member 224 within the two connecting plates 223 and the avoidance groove 2221. It should be understood that by spacing the two connecting plates 223 apart, providing the avoidance groove 2221 on the bottom plate 222, and allowing the lower end of the swing block 230 to pass through the avoidance groove 2221, the swing block 230 located in the middle of the connecting plates 223 has sufficient rotation space. Thus, the swing block 230 can be set to be longer without affecting the rotation range of the swing block 230, ensuring the contact area between the swing block 230 and the pallet.

[0046] Specifically, the above-mentioned guiding surface 2231 is formed on the connecting plate 223.

[0047] Refer to Figure 2 and Figure 4 , according to some embodiments of the present application, the push plate module 200 further includes a support plate 240. The push plate driving assembly 210 is drivingly connected to the support plate 240. There are multiple base 220s, and the swing blocks 230 correspond to the base 220s one by one. The multiple base 220s are disposed on the support plate 240 and are distributed in the left - right direction.

[0048] It can be understood that by connecting the multiple base 220s through the support plate 240, the push plate driving assembly 210 can push the base 220 to drive the multiple base 220s and the swing blocks 230 to move.

[0049] Specifically, in this embodiment, both the base 220 and the swing block 230 include two. In other embodiments, the base 220 and the swing block 230 can also include more than two, which is not limited herein.

[0050] Refer to Figure 2 and Figure 4 , according to some embodiments of the present application, the side of the conveying module 100 facing the push plate module 200 is provided with a guide rail 140. The guide rail 140 is provided with a chute 141. The left and right sides of the support plate 240 are provided with rollers 241 and bearings 242. The rollers 241 are slidably disposed in the chute 141, and the bearings 242 are slidably engaged with the end face of the guide rail 140.

[0051] It can be understood that the guide rail 140 is arranged in the front - rear direction. By the sliding fit of the rollers 241 on the support plate 240 with the chute 141 and the sliding fit of the rotating shaft with the end face of the guide rail 140, the moving stability of the support plate 240 is improved.

[0052] Referring to Figures 1 to 3 , according to some embodiments of the present application, the push - plate driving assembly 210 includes a motor 211, a belt 212, at least two transmission rods 213, and at least two transmission wheels 214. The two ends of the transmission rod 213 are rotatably connected to the sides of the two conveying modules 100. The two transmission rods 213 are distributed in the front - rear direction. At least one transmission wheel 214 is fixedly connected to each transmission rod 213. The belt 212 is wound around the transmission wheels 214 on the two transmission rods 213. The motor 211 is drivingly connected to the transmission rod 213, and the base 220 is rotatably and fixedly connected to the belt 212.

[0053] It can be understood that the motor 211 drives the transmission rod 213 to rotate. The transmission rod 213 drives the transmission wheel 214 above it to rotate. The transmission wheel 214 drives the belt 212 to rotate and drives the other transmission rod 213 to rotate. Since the base 220 is fixedly connected to the support plate 240, when the belt 212 rotates, it can drive the base 220 to move forward. When the motor 211 adjusts the rotation direction, the belt 212 can drive the base 220 to move backward so that the base 220 returns to the rear end of the board - conveying mechanism.

[0054] Specifically, the bottom plate 222 is fixedly connected to the belt 212 through the support plate 240.

[0055] Referring to Figure 1 and Figure 3 , according to some embodiments of the present application, the conveying module 100 includes a conveying driving assembly 110, a conveying frame 120, and a plurality of guide rollers 130. The guide rollers 130 are rotatably arranged on the conveying frame 120. The conveying driving assembly 110 is drivingly connected to the guide rollers 130. The push - plate module 200 is located between the conveying frames 120 of the two conveying modules 100.

[0056] It can be understood that the guide rollers 130 are distributed in the front - rear direction on the conveying frame 120. The guide rollers 130 are used to support the left and right ends of the pallet. The conveying driving assembly 110 drives the guide rollers 130 to rotate self - rotatably so that the guide rollers 130 have a driving force to drive the pallet to move forward, thereby cooperating with the push - plate module 200 that pushes the middle of the pallet to be able to stably push the pallet and keep the pallet balanced.

[0057] Specifically, the above - mentioned guide rail 140 is arranged on one side of the conveying frame 120 facing the push - plate module 200.

[0058] Referring to Figure 1, according to some embodiments of the present application, the conveying module 100 further includes a transition plate 150, and the transition plate 150 is disposed at the front end of the conveying rack 120.

[0059] It can be understood that, in order to ensure that the pallet can be stably conveyed to the second conveying line, a transition plate 150 is provided at the front end of the conveying rack 120. Thus, when the pallet is conveyed to the front end of the plate conveying mechanism and is about to enter the second conveying line, the front parts of the left and right ends of the pallet are supported by the transition plate 150, and the rear parts are continuously conveyed by the guide rollers 130. Moreover, the guide rollers 130 cooperate with the push plate module 200 to continue to push the pallet forward into the second conveying line. The front parts of the left and right ends of the pallet will enter the second conveying line and be conveyed by the second conveying line, while the rear parts are supported by the transition plate 150. At the same time, the swing block 230 continues to push the pallet to make the pallet completely enter the second conveying line. Therefore, by providing the transition plate 150, the pallet can enter the second conveying line through the transition plate 150, avoiding the pallet from slipping and shifting due to the inconsistent conveying speeds of the guide rollers 130 and the second conveying line, so as to ensure the stable conveying of the pallet and the correct posture of the pallet when it is conveyed to the second conveying line.

[0060] The embodiments of the present application have been described in detail above with reference to the accompanying drawings. However, the present application is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
