Description

Technical Field

[0001] This application relates to the field of papermaking technology, specifically to a pulp board packaging paper insertion machine. Background Technology

[0002] In the pulp board production process, from cutting to packaging, the pulp board needs to go through the pulp board packaging paper feeding machine to place the pulp wrapping paper and package it.

[0003] During transportation, pulp sheets undergo multiple transfers via a conveyor chain. During this process, the bottom layer of pulp sheets often becomes damaged and stained, rendering them unusable as packaging paper. When there are few pulp sheets available, production staff must closely monitor the pulp board packaging paper feeding machine and manually stop and remove the last sheet. This manual monitoring is inefficient, and if staff are not timely in their monitoring, the last sheet may end up being placed into a pulp bale for packaging, requiring repackaging and rework, thus reducing production efficiency. Utility Model Content

[0004] In view of the above problems, this application provides a pulp board packaging paper insertion machine, which solves the problem that in the process of conveying pulp wrappers, the production personnel manually remove the last pulp wrapper, which wastes manpower and reduces production efficiency if the last pulp wrapper is not removed in time, requiring repackaging and rework.

[0005] To achieve the above objectives, the inventor provides a pulp board packaging paper insertion machine, comprising:

[0006] A pulp sheet conveyor chain, which is used to convey the pulp sheet produced by the cutting machine to the inlet of the insertion machine;

[0007] A pulp sheet lifting device is used to lift the pulp sheet placed in the machine inlet to a preset position;

[0008] The suction device is used to pick up the first sheet of sizing from the sizing lifting device;

[0009] A paper feeding device, which drives a suction device to deliver pulp wrappers to a paper receiving device;

[0010] A paper-feeding device that feeds pulp bag skin into the pulp bag;

[0011] A folding device for folding the outer skin of a sty;

[0012] The sensing device is used to sense whether there is a slurry sheath on the slurry sheath lifting device;

[0013] A control device, the control device being connected to the sensing device and the sending device;

[0014] An alarm device is connected to the control device.

[0015] In some embodiments, the sensing device is installed in the slurry lifting device.

[0016] In some embodiments, the sensing device is a photoelectric switch.

[0017] In some embodiments, the photoelectric switch is an infrared sensor E3ZG-D82.

[0018] In some embodiments, the control device includes a programmable logic controller (PLC).

[0019] In some embodiments, a height adjustment device is also included for attaching the slurry bag skin to the slurry bag.

[0020] In some embodiments, the device further includes a height adjustment mechanism, and the suction device includes a vacuum suction cup.

[0021] In some embodiments, the alarm device includes a voice announcer.

[0022] Unlike existing technologies, the above technical solution involves conveying the pulp wrappers produced by the cutting machine to a pulp wrapper lifting device at the entrance of the pulp board packaging paper placement machine via a pulp wrapper conveyor chain. The lifting device then raises the wrapper to a preset position, where a suction device picks up the top wrapper from the lifting device. The device then drives the suction device to deliver the wrapper to a receiving device. Once the receiving device is ready, the wrapper is fed into a pulp bale. A folding device folds the wrapper on the bale before it is sent out of the pulp board packaging paper placement machine. A sensing device detects the wrapper's movement. When the last sheet of pulp on the lifting device is removed, it sends a signal to the control device. The control device then activates the paper feeding device and triggers an alarm to remind production personnel to replace the pulp sheet. This eliminates the need for production staff to constantly monitor the pulp sheet lifting device, avoiding wasted manpower. Furthermore, once the last sheet of pulp is removed, the paper feeding device can be stopped immediately to prevent the last sheet from being fed onto the pulp bundle, thus avoiding reduced production efficiency due to subsequent repackaging and rework.

[0050] Existing pulp board packaging paper loading machines typically consist of a pulp bundle conveyor chain, a pulp bundle lifting device, a bundle suction device, a paper feeding device, a paper receiving device, a height adjustment device, and a folding device. Pulp bundles 210 produced by the cutting machine are conveyed to the inlet of the pulp board packaging paper loading machine via the conveyor chain. They are then lifted to their highest position by the pulp bundle lifting device, where the top pulp bundle 210 is sucked up by the bundle suction device. The paper feeding device then delivers two bundles (upper and lower) to the paper receiving device. After receiving, the chain conveyor feeds the pulp bale, and the height adjustment device presses down to ensure the pulp bundle 210 adheres tightly to the bale and does not shift. Finally, the folding device folds the bundle before sending it out of the loading machine. During the process of feeding the pulp sheet 210 from the pulp sheet lifting device into the paper feeding device, production personnel need to pay attention to the pulp sheet 210 on the pulp sheet lifting device. This process will result in a waste of manpower. At the same time, if the last pulp sheet 210 on the pulp sheet lifting device is not noticed in time and is sent into the pulp bag for packaging, it will cause repackaging and rework, reducing production efficiency.

[0051] Please see Figure 1-3 To avoid wasting manpower and reducing production efficiency due to repackaging and rework, this embodiment provides a pulp board packaging paper insertion machine, including:

[0052] The pulp coating conveyor chain 110110 is used to convey the pulp coating 210 produced by the cutting machine to the inlet of the insertion machine;

[0053] The pulp sheath lifting device 120 is used to lift the pulp sheath 210 placed in the machine inlet to a preset position;

[0054] The suction device 130 is used to suck up the first sheet of sizing skin 210 on the sizing skin lifting device 120;

[0055] Paper feeding device 140, which is used to drive the suction device 130 to send the pulp wrapper 210 to the paper receiving device 150;

[0056] Paper receiving device 150, which feeds pulp bag skin 210 into pulp bag;

[0057] Folding device 160, the folding device 160 being used to fold the sizing skin 210;

[0058] The sensing device 170 is used to sense whether there is a sludge 210 on the sludge lifting device 120;

[0059] Control device 180, the control device 180 being connected to the sensing device 170 and the sending device;

[0060] An alarm device 190 is connected to the control device 180.

[0061] After the cutting machine produces pulp wrappers 210, the pulp wrapper conveyor chain 110 transports the pulp wrapper 210 to the pulp wrapper lifting device 120 at the entrance of the pulp board packaging paper loading machine. The pulp wrapper lifting device 120 then rises to a preset position, and the suction device 130 picks up the top pulp wrapper 210 from the lifting device 120. The drive device then moves the suction device 130 to the receiving device, where the pulp wrapper 210 is fed into the pulp bale. The folding device 160 folds the pulp wrapper 210 on the pulp bale before sending it out of the pulp board packaging paper loading machine. The sensing device 170 senses the pulp wrapper 210 on the pulp wrapper lifting device 120. When the last sheet of pulp wrapper 210 on the pulp wrapper lifting device 120 is detected to be removed, a signal is output to the control device 180. The control device 180 then enables the paper feeding device 140 to operate and issues an alarm via the alarm device 190 to remind production personnel to replace the pulp wrapper 210. This eliminates the need for production personnel to constantly monitor the pulp wrapper 210 on the pulp wrapper lifting device 120, thus avoiding wasted manpower. Furthermore, once the last sheet of pulp wrapper 210 is removed from the pulp wrapper lifting device 120, the paper feeding device 140 can be stopped immediately to prevent the last sheet of pulp wrapper 210 from being fed onto the pulp bundle, thus avoiding subsequent repackaging and rework, and consequently preventing the reduction in production efficiency caused by subsequent repackaging and rework.

[0062] In some embodiments, the sensing device 170 is mounted on the slurry lifting device 120.

[0063] A sensing device 170 is installed on the pulp sheet lifting device 120 to sense whether there is pulp sheet 210 on the pulp sheet lifting device 120. When there is pulp sheet 210 on the pulp sheet lifting device 120, a normally closed signal is output. When the last pulp sheet 210 on the pulp sheet lifting device 120 is removed, a normally open signal is output. In other embodiments, the sensing device 170 can also be set at a preset position on the lifting path of the pulp sheet lifting device 120 of the pulp board packaging paper feeding machine. When the pulp sheet lifting device 120 is raised to a preset height, it senses the pulp sheet 210 on the pulp sheet lifting device 120.

[0064] In some embodiments, the sensing device 170 is a photoelectric switch. By using a photoelectric switch as the sensing device 170, installed at the bottom of the pulp sheet lifting device 120, it detects the last pulp sheet 210 on the pulp sheet lifting device 120. The photoelectric switch is in the default activated state when the pulp sheet 210 is in position. If the pulp sheet 210 on the pulp sheet lifting device 120 is less than 3mm, the photoelectric switch cannot be activated, indicating that only one pulp sheet 210 remains on the pulp sheet lifting device 120. Preferably, the photoelectric switch is an infrared sensor E3ZG-D82. The infrared sensor E3ZG-D82 is a photoelectric switch with strong anti-interference capability and stable performance, which can accurately sense the pulp sheet 210 on the pulp sheet lifting device 120. When the photoelectric switch detects a pulp sheet 210 on the pulp sheet lifting device 120, it outputs an action signal (closed point) to the control device 180. After the pulp sheet 210 is grasped by the suction device 130, it can be normally conveyed in the pulp board packaging paper feeding machine. When the last sheet of pulp 210 is picked up on the pulp liner lifting device 120, the photoelectric switch outputs a normally open signal to the control device 180. After the last sheet of pulp 210 is clamped by the paper feed roller of the paper feeding device 140, the conveying action will not be completed. The control device 180 will then trigger an alarm via the alarm device 190, reminding the process personnel to replace the pulp liner 210. In other embodiments, the sensing device 170 can also use other inductive switches, such as magnetic switches, capacitive proximity switches, inductive proximity switches, or pressure sensors.

[0065] In some embodiments, the control device 180 includes a programmable logic controller (PLC). A PLC is a digital electronic system specifically designed for industrial applications. It employs a programmable memory that stores instructions for performing logical operations, sequential control, timing, counting, and arithmetic operations, controlling various types of machinery or production processes through digital or analog inputs and outputs. In other embodiments, the control device 180 may also employ other controllers, such as microcontrollers or computers.

[0066] Please see Figure 1 In some embodiments, a height adjustment device 1100 is also included, which is used to attach the pulp bag skin 210 to the pulp bag. In order to ensure that the pulp bag skin 210 is attached to the pulp bag when folding, the height adjustment device 1100 is pressed down after the pulp bag skin 210 is fed into the pulp bag to ensure that the pulp bag skin 210 is attached to the pulp bag and does not shift, and then folded by the folding device 160.

[0067] In some embodiments, the device further includes a height adjustment device 1100, and the suction device 130 includes a vacuum suction cup. The suction device 130 mainly relies on the vacuum suction cup to grip the pulp coating 210, which can avoid damage to the pulp coating 210 during the gripping process.

[0068] In some embodiments, the alarm device 190 includes a voice announcer. The alarm device 190 uses a voice announcer to remind process personnel to replace the last sheet of sizing sheath 210 after it has been removed from the sizing sheath lifting device 120. In other instances, the alarm device 190 may also employ an audible and visual alarm, a touchscreen, etc.

[0069] In some embodiments, a pulp board packaging paper feeding machine has a sensing device 170 installed below the pulp sheet 210 storage area of ​​the pulp sheet lifting device 120. When the last pulp sheet 210 is picked up, the sensing device 170 transmits a signal to the PLC, automatically stopping the replenishment action of the pulp sheet conveyor chain 110110 in the program, and alarming on the touch screen to remind the process personnel to handle the last pulp sheet 210. The sensing device 170 consists of two types: a photoelectric switch and a magnetic switch. The photoelectric switch is used to detect the last pulp sheet 210. This switch is installed at the bottom and is activated by default when the pulp sheet 210 is in place. If the pulp sheet is less than 3mm thick, the photoelectric switch cannot be activated, indicating that the last pulp sheet 210 has been picked up.

[0070] Specifically, an infrared sensor (Omron E3ZG-D82) is added to the lower part of the pulp wrapper 210 storage area of ​​the pulp wrapper lifting device 120 to detect whether there is pulp wrapper 210 on the pulp wrapper lifting device 120. The pulp wrapper lifting device 120 is a component of the loading machine, and its function is to raise the pulp wrapper 210 to its highest position and then suck up the pulp wrapper 210 and send it to the paper receiving device 150.

[0071] Principle: When the infrared sensor detects a sheet of pulp 210 above, the sensor outputs an action signal (closed point), and the sheet of pulp 210 is picked up and can be normally conveyed to the feeding machine. When the last sheet of pulp 210 is picked up, the sensor outputs a normally open signal. The sheet of pulp 210 will be clamped by the paper feed roller and will not complete the conveying action, and an alarm will be triggered to remind the process personnel to replace the sheet of pulp 210.

[0072] Simultaneously, an alarm is added for the last sheet of slurry sheath 210. When the slurry sheath 210 elevator is at its highest point, the system senses that the last sheet of slurry sheath 210 has been picked up and outputs an alarm signal to remind the operator to replace the slurry sheath 210.

[0073] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
