Description

Technical Field

[0001] The present invention relates to the technical field of feeding devices, and more particularly to a feeding device for the production and processing of packaging paper boxes. Background Art

[0002] The feeding device is an important equipment on the production line of packaging paper boxes. It is responsible for stably and efficiently transporting the raw materials of the packaging paper boxes to be processed to the next process. The common feeding device mainly consists of a transmission rack, a conveyor belt, a transmission group, a servo motor, conveying rollers, and a control system. The specific process of the feeding device for transporting the packaging boxes is as follows: Place the raw materials of the packaging paper boxes to be processed on the conveyor belt under the transmission rack. At the same time, the control system drives the servo motor to input a stable working current. Through the transmission of the transmission group, the conveying rollers are driven to rotate, thereby driving the conveyor belt to rotate synchronously, and then driving the packaging boxes on the surface of the conveyor belt into the next process;

[0003] In the actual operation process, we found the following problems with the feeding device: The adaptability of the feeding device is insufficient. The main reason for this problem is that although the feeding device is usually applicable to raw materials of packaging paper boxes of various specifications and sizes, in some extreme cases, such as particularly large paper boxes, it may not be able to adapt well, which may lead to problems such as poor transmission or jamming, and then reduce the overall production efficiency of the packaging paper boxes; At the same time, during the actual production process of the packaging paper boxes, quality inspection operations need to be carried out on the paper boxes. This process is mainly carried out manually. At the same time, during the quality inspection process, the conveying speed of the conveyor belt may be affected and reduced, so the overall production efficiency of the packaging paper boxes is reduced, and then the overall production cost is increased;

[0004] Therefore, now we urgently need a feeding device for the production and processing of packaging paper boxes to solve the above-mentioned existing technical problems. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a feeding device for the production and processing of packaging paper boxes to solve the problems existing in the above-mentioned background art.

[0006] The present invention provides the following technical solutions: A feeding device for the production and processing of packaging paper boxes, comprising:

[0007] A transmission rack, wherein a control system is arranged inside the transmission rack;

[0008] A power supply mechanism for providing the conveying power for feeding the packaging paper boxes, wherein it is installed on the side of the transmission rack;

[0009] Conveyor belt, used for transporting packaging cartons, where the number of conveyor belts is two groups. A weight sensor is set at the middle position of one group of conveyor belts. The weight sensor and the one group of conveyor belts do not interfere with each other. And on the premise of not affecting the normal operation of the one group of conveyor belts, the weight sensor detects the weight of the packaging cartons on this group of conveyor belts and generates weight data to be transmitted to the control system. An electric control lifting frame is set at the middle position of the other group of conveyor belts. The electric control lifting frame and the other group of conveyor belts do not interfere with each other. And on the premise of not affecting the normal operation of the other group of conveyor belts, the electric control lifting frame performs a position lifting operation on the packaging cartons on this conveyor belt. The conveying power generated by the power supply mechanism is transmitted to the two groups of conveyor belts to control the two groups of conveyor belts to synchronously convey the packaging cartons;

[0010] Auxiliary plates, used to assist the conveyor belt in transporting packaging cartons, where the number of auxiliary plates is two groups. The two groups of auxiliary plates are symmetrically distributed and installed on both sides of the top of the transmission frame with the central axis of the transmission frame as the symmetry line.

[0011] Furthermore, the number of the auxiliary plates is two groups. Electric control telescopic plates are installed on the adjacent sides of the two groups of auxiliary plates. The electric control telescopic plates input a stable working current to drive the distance between the two groups of auxiliary plates to change. On the inner surfaces of the two groups of electric control telescopic plates, placing grooves are opened along the main path direction of the material transmission of the two groups of conveyor belts.

[0012] Furthermore, an electric control lifting column is installed at the middle position of the bottom surface of the placing groove. A frame is installed on the upper surface of the electric control lifting column. The geometric midpoint of the frame and the geometric midpoint of the electric control lifting column are on the same straight line. And auxiliary wheels are sequentially and equidistantly movably sleeved on the inner side surfaces of the frame, which are used to assist the large packaging cartons to be conveyed under the action of the conveyor belt.

[0013] Furthermore, two groups of auxiliary brackets are installed on the side surface of one group of auxiliary plates. The two groups of auxiliary brackets are symmetrically installed on the side surface of this group of auxiliary plates with the central axis of one group of auxiliary plates as the symmetry line. The installation position of this group of auxiliary plates is far from the conveyor belt. Electric control hydraulic columns are installed on the top of the side surfaces of the two groups of auxiliary brackets close to the auxiliary plates. A limiting plate is installed at the output end of the electric control hydraulic column. Two air pumps are installed on the side surface of the limiting plate close to the auxiliary bracket position. The two air pumps are symmetrically installed on the side surface of the limiting plate with the central axis of the limiting plate as the symmetry line.

[0014] Furthermore, a plurality of air grooves are sequentially and equidistantly opened on the inner side surface of the limiting plate far from the auxiliary bracket position. Rubber rings are installed at the positions of each group of air grooves on this auxiliary bracket. Sliding grooves are opened at the positions of each group of air grooves on the limiting plate. Push plates are sleeved in the sliding grooves. Telescopic tubes are installed in the middle areas of each group of push plates close to the auxiliary bracket position.

[0015] Further, a porous air outlet pipe is installed at the output end of the air pump. The porous air outlet pipe has multiple groups of air outlet holes, and each group of air outlet holes is sequentially installed inside each group of air grooves and each group of telescopic pipes. A pressure sensor is installed in each group of air grooves to detect the air pressure data in each group of air grooves and transmit it to the control system.

[0016] Further, a servo motor is installed on the inner wall at the middle position of the limit plate. A transmission rod is installed at the output end of the servo motor. An electric control lifting plate is installed at the middle position of the transmission rod. A gripper plate is installed on the upper surface of the electric control lifting plate. A position adjustment mechanism is installed on the upper surface of the gripper plate. An auxiliary gripper is installed at the output end of the position adjustment mechanism.

[0017] Further, the control system includes a quality inspection unit and an adjustment unit. When the quality inspection unit simulates the analog weight data generated by the weight sensor when the packaging carton meets the production standard and integrates the data within the production standard range, the quality inspection unit compares the real-time weight data with the standard range. When the real-time weight data is not within this range, it is determined that the packaging carton does not meet the production standard;

[0018] The adjustment unit simulates the analog air pressure data generated by the pressure sensor when the packaging carton is being transported normally on the conveyor belt surface and integrates the analog air pressure data to form a threshold range. The adjustment unit compares the real-time pressure data with the threshold range. When the real-time pressure data is not within the threshold range, it is determined that the packaging carton being transported on the conveyor belt surface has a position deviation.

[0019] The technical effects and advantages of the present invention:

[0020] 1. When the control system of the present invention determines that the production specification of the packaging carton exceeds the transportation specification of the conveyor belt, a stable working current is input to the electric control lifting column and the electric control telescopic plate, and the distance between the two auxiliary plates is adjusted to be adapted to the production specification of the packaging carton. A stable working current is input to the electric control lifting column, which drives the auxiliary wheels to move out of the placement groove, facilitating the transportation of the packaging carton of this specification on the conveyor belt surface, and further improving the adaptability of the present application to the transportation of packaging cartons of different specifications.

[0021] 2. The control system of the present invention determines whether the packaging carton on the conveyor belt surface has a deviation by analyzing the change in the air pressure data. When the control system determines that the packaging carton has a deviation, a stable working current is input to the electro-hydraulic column to generate compressed air and input it into the corresponding telescopic pipe, controlling the telescopic pipe to stretch, thereby driving the corresponding push plate to squeeze against the packaging carton to adjust the transportation position of the packaging carton.

Detailed implementation manners

[0029] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the drawings in the present invention. In addition, the forms of each structure described in the following embodiments are merely examples, and a feeding device for producing and processing packaging paper boxes according to the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0030] Referring to Figures 1 to 2 as shown, the present invention provides a feeding device for producing and processing packaging paper boxes, including a transmission rack 1, wherein a control system is arranged inside the transmission rack 1;

[0031] a power supply mechanism 2 for providing the conveying power for feeding the packaging paper boxes, wherein the transmission rack 1 is installed on the side of the transmission rack 1;

[0032] The conveyor belt 3 is used to transport packaging cartons. There are two sets of conveyor belts 3. A weight sensor 5 is arranged at the middle position of one set of conveyor belts 3. The weight sensor 5 does not interfere with the one set of conveyor belts 3. And on the premise of not affecting the normal operation of the one set of conveyor belts 3, the weight sensor 5 detects the weight of the packaging cartons on this set of conveyor belts 3 and generates weight data to be transmitted to the control system. An electric control lifting frame 4 is arranged at the middle position of the other set of conveyor belts 3. The electric control lifting frame 4 does not interfere with the other set of conveyor belts 3. And on the premise of not affecting the normal operation of the other set of conveyor belts 3, the electric control lifting frame 4 performs a position lifting operation on the packaging cartons on this conveyor belt 3. The conveying power generated by the power supply mechanism 2 is transmitted to the two sets of conveyor belts 3 to control the two sets of conveyor belts 3 to synchronously convey the packaging cartons;

[0033] The auxiliary plates 6 are used to assist the conveyor belt 3 in transporting the packaging cartons. There are two sets of auxiliary plates 6. The two sets of auxiliary plates 6 are symmetrically distributed and installed on both sides of the top of the transmission rack 1 with the central axis of the transmission rack 1 as the symmetry line.

[0034] In the embodiment of the present application, the geometric midpoint of the two sets of conveyor belts 3 is on the same straight line to ensure the stable conveyance of the packaging cartons.

[0035] The specific working process of this part of the embodiment of the application is as follows: The packaging cartons are transported to the surface of one set of conveyor belts 3. The power supply mechanism 2 inputs a stable working current to drive the two sets of conveyor belts 3 to synchronously convey the packaging cartons. During the conveyance of the packaging cartons, the weight sensor 5 detects the weight of the packaging cartons. The weight sensor 5 generates corresponding weight data and transmits it to the control system. The control system analyzes the weight data to judge whether the production instruction of the packaging cartons meets the standard. When it is judged that the packaging cartons do not meet the production standard, when the packaging cartons move to the upper surface position of the electric control lifting frame 4, the electric control lifting frame 4 inputs a stable working current to drive the packaging cartons out of the surface of the conveyor belt 3 for convenient further processing.

[0036] Refer to Figures 1 to 4 As shown in the figure, the present invention provides a feeding device for the production and processing of packaging cartons. There are two sets of auxiliary plates 6. Electric control telescopic plates 601 are installed on the adjacent sides of the two sets of auxiliary plates 6. The electric control telescopic plates 601 input a stable working current to drive the distance between the two sets of auxiliary plates 6 to change. On the inner surfaces of the two sets of electric control telescopic plates 601, placing grooves are opened along the main path direction of the material conveyance of the two sets of conveyor belts 3;

[0037] An electric control lifting column 602 is installed at the middle position of the bottom surface of the placement groove. A frame 603 is installed on the upper surface of the electric control lifting column 602. The geometric center line point of the frame 603 and the geometric center line point of the electric control lifting column 602 are on the same straight line. And auxiliary wheels 604 are sequentially and equidistantly movably sleeved on the inner side surface of the frame 603, which are used to assist the large packaging cartons to be conveyed under the action of the conveyor belt 3.

[0038] In the embodiment of the present application, the specific working process of this part of the embodiment is as follows: When the control system determines that the production specification of the packaging carton exceeds the transportation specification of the conveyor belt 3, a stable working current is input to the electric control lifting column 602 and the electric control telescopic plate 601, and the distance between the two groups of auxiliary plates 6 is adjusted to be adapted to the production specification of the packaging carton. A stable working current is input to the electric control lifting column 602, which drives the auxiliary wheels 604 to move out of the placement groove, facilitating the transportation of the packaging cartons of this specification on the surface of the conveyor belt 3, further improving the adaptability of the present application to the transportation of different specifications of packaging cartons.

[0039] Referring to Figures 1 to 5 As shown in the figure, the present invention provides a feeding device for the production and processing of packaging cartons. Two groups of auxiliary brackets 704 are installed on the side surface of a group of auxiliary plates 6. The two groups of auxiliary brackets 704 are symmetrically installed on the side surface of this group of auxiliary plates 6 with the central axis of a group of auxiliary plates 6 as the symmetry line. The installation position of this group of auxiliary plates 6 is far from the conveyor belt 3. Electric control hydraulic columns 705 are installed at the top of the side surfaces of the two groups of auxiliary brackets 704 close to the auxiliary plates 6. A limiting plate 7 is installed at the output end of the electric control hydraulic column 705. Two groups of air pumps 703 are installed on the side surface of the limiting plate 7 close to the auxiliary bracket 704. The two groups of air pumps 703 are symmetrically installed on the side surface of the limiting plate 7 with the central axis of the limiting plate 7 as the symmetry line;

[0040] A plurality of groups of air grooves are sequentially and equidistantly opened on the inner side surface of the limiting plate 7 far from the auxiliary bracket 704. Rubber rings 701 are installed at the positions of each group of air grooves of the auxiliary bracket 704. Sliding grooves are opened at the positions of each group of air grooves of the limiting plate 7. Push plates 702 are sleeved in each of the sliding grooves. A telescopic tube 706 is installed in the middle area of each push plate 702 close to the auxiliary bracket 704;

[0041] The output end of the air pump 703 is installed with a porous air outlet pipe 707. The porous air outlet pipe 707 has a plurality of air outlet holes, and each group of air outlet holes is sequentially installed inside each group of air grooves and each group of telescopic tubes 706. Pressure sensors are installed in each group of air grooves, which are used to detect the air pressure data in each group of air grooves and transmit it to the control system.

[0042] In the embodiment of the present application, solenoid valves are installed in the plurality of air outlet holes of the porous air outlet pipe 707 to control the flow direction of the gas.

[0043] The specific working process of the embodiment of this application is as follows: When the packaging carton is being transported, the electric control hydraulic column 705 inputs a stable working current to drive the limit plate 7 to move to a distance suitable for the packaging carton. At the same time, the air pump 703 inputs a stable working current to generate compressed air and transport it into each group of air grooves. When the conveyor belt 3 is transporting the packaging carton, if the packaging carton transported on the surface of the conveyor belt 3 is displaced, the packaging carton contacts the surface of one side of the rubber ring 701, and the rubber ring 701 deforms. Therefore, the air pressure data in the air groove changes correspondingly. The control system judges whether the packaging carton on the surface of the conveyor belt 3 is displaced by the change of the air pressure data. When the control system judges that the packaging carton is displaced, the electric control hydraulic column 705 inputs a stable working current to generate compressed air and input it into the corresponding telescopic tube 706, controlling the telescopic tube 706 to stretch, so as to drive the corresponding push plate 702 to squeeze the packaging carton, so as to adjust the transportation position of the packaging carton.

[0044] Referring to Figures 1 to 6 As shown, the present invention provides a feeding device for the production and processing of packaging cartons. A servo motor 801 is installed on the inner wall at the middle position of the limit plate 7. The output end of the servo motor 801 is installed with a transmission rod 802. An electric control lifting plate 8 is installed at the middle position of the transmission rod 802. A gripping plate 803 is installed on the upper surface of the electric control lifting plate 8. A position adjusting mechanism 805 is installed on the upper surface of the gripping plate 803. The output end of the position adjusting mechanism 805 is installed with an auxiliary gripper 804.

[0045] In the embodiment of this application, the specific working process of this part of the embodiment is as follows: When the control system judges that the packaging carton does not meet the production standard, the electric control lifting plate 8, the electric control lifting plate 8 and the position adjusting mechanism 805 input a stable working current to drive the gripping plate 803 to move near the packaging carton. At the same time, the position adjusting mechanism 805 controls the two groups of auxiliary grippers 804 to grip the packaging carton. At the same time, the servo motor 801 inputs a reverse current to facilitate the packaging carton to move out of the transportation range of the conveyor belt 3, so as to collect and process the unqualified packaging cartons.

[0046] Referring to Figures 1 to 6 As shown, the control system includes a quality inspection unit and an adjustment unit. When the quality inspection unit simulates the analog weight data generated by the weight sensor 5 when the packaging carton meets the production standard and integrates the data production standard range, the quality inspection unit compares the real-time weight data with the standard range. When the real-time weight data is not within this range, it is judged that the packaging carton does not meet the production standard;

[0047] When the adjustment unit simulates the normal transportation of the packaging carton on the surface of the conveyor belt 3, it generates simulated air pressure data produced by the pressure sensor, and integrates the simulated air pressure data to form a threshold range. The adjustment unit compares the real-time pressure data with the threshold range. When the real-time pressure data is not within the threshold range, it is determined that the packaging carton transported on the surface of the conveyor belt 3 has a position offset situation.

[0048] The specific working process of this application is as follows:

[0049] Step 1: The packaging carton is transported to the surface of a group of conveyor belts 3, and the power supply mechanism 2 inputs a stable working current to drive the two groups of conveyor belts 3 to synchronously transport the packaging carton. During the transportation of the packaging carton, the weight sensor 5 detects the weight of the packaging carton, generates corresponding weight data and transmits it to the control system. The control system analyzes the weight data to determine whether the production instruction of the packaging carton meets the standard. When it is determined that the packaging carton does not meet the production standard, when the packaging carton moves to the upper surface position of the electric control lifting frame 4, the electric control lifting frame 4 inputs a stable working current to drive the packaging carton out of the surface of the conveyor belt 3, facilitating its next processing;

[0050] When the control system determines that the packaging carton does not meet the production standard, the electric control lifting plate 8, the electric control lifting plate 8, and the position adjustment mechanism 805 input a stable working current to drive the gripper plate 803 to move near the packaging carton. At the same time, the position adjustment mechanism 805 controls the two groups of auxiliary grippers 804 to grab the packaging carton. At the same time, the servo motor 801 inputs a reverse current to facilitate the packaging carton to move out of the conveying range of the conveyor belt 3, so as to collect and process the unqualified packaging cartons;

[0051] Step 2: When the packaging carton is in the conveying operation, the electric control hydraulic column 705 inputs a stable working current to drive the limiting plate 7 to move to a distance suitable for the packaging carton. At the same time, the air pump 703 inputs a stable working current to generate compressed air and transport it into each air groove. When the conveyor belt 3 transports the packaging carton, if the packaging carton transported on the surface of the conveyor belt 3 has a position offset situation, the packaging carton contacts the surface of one side of the rubber ring 701, and the rubber ring 701 deforms. Therefore, the air pressure data in the air groove changes correspondingly. The control system judges whether the packaging carton on the surface of the conveyor belt 3 has an offset situation through the change of the air pressure data. When the control system judges that the packaging carton has an offset situation, the electric control hydraulic column 705 inputs a stable working current to generate compressed air and input it into the corresponding telescopic tube 706, controlling the telescopic tube 706 to stretch, so as to drive the corresponding push plate 702 to squeeze the packaging carton, so as to adjust the transportation position of the packaging carton;

[0052] Step 3: When the control system determines that the production specification of the packaging carton exceeds the transportation specification of the conveyor belt 3, the electric control lifting column 602 and the electric control telescopic plate 601 input a stable working current, control the distance between the two groups of auxiliary plates 6 to be adjusted to match the production specification of the packaging carton, and the electric control lifting column 602 inputs a stable working current to drive the auxiliary wheel 604 out of the placement groove, facilitating the transportation of the packaging carton of this specification on the surface of the conveyor belt 3.
