Description

Technical Field

[0001] The utility model relates to the technical field of packaging box processing, in particular to a humidifying device for a packaging paper shell production line. Background Art

[0002] In modern industrial production, various packaging technologies emerge in an endless stream. However, with the emergence of the express delivery industry, the application of cartons has been widely promoted, which has led to a sharp increase in the demand for paper shells. However, in the production of paper shells, temperature changes in different seasons affect the ratio and dryness of paper shells. In winter production, the base paper used is dry and the local humidity of the base paper is low. The rapid cutting, slotting and folding of the machine is prone to form depressions or protrusions in the local area, which makes the paper shell forming effect poor and is easily scrapped. A Chinese patent with announcement number CN201711468615.7 proposes a humidifying device for paperboard production, including a centrifugal pump, a water reservoir, a transmission roller and two spray devices, wherein the spray pipe is provided with a plurality of water spray outlets along the length direction, each of the water spray outlets is provided with an independent electric control valve, and a plurality of humidity sensors are provided, the humidity sensors correspond to the spray holes one by one, the spray device also includes a comparator, the input end of the comparator is electrically connected to the output end of each of the humidity sensors, and the output end of the comparator is electrically connected to the control end of all the electric control valves; the comparator generates a control signal corresponding to each water spray outlet according to the comparison result between the measured value of each humidity sensor and the preset comparison value, and sends it to the electric control valve corresponding to the water spray outlet.

[0003] The defect of the above scheme is that since the humidifying device is added during the gluing process of the paper shell to prevent bulging of the paper shell during gluing, the installation of the spray device is strictly fixed on the edge of the paper shell to be glued. In the actual production process of our company, we found that the paper shell after the cutting process is prone to cracking and damage during folding due to excessively dry weather. Therefore, it is necessary to humidify the paper shell output port after the folding process. At the same time, since our company produces different types of paper shells at the same time, the folding directions and positions of different paper shells are different. It is difficult to adapt to the humidification of multiple paper shells by only fixing the humidifying device in one position. Utility Model Content

[0004] The utility model provides a humidifying device for a packaging paper shell production line to solve the problem that the existing paper shell is easily damaged during folding due to excessive dry weather before folding.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is as follows: comprising a bracket located at the tail of the production line, a channel for outputting the packaging paper shell is provided at the tail of the production line, and a transmission line capable of horizontally transmitting the paper shell to be folded is provided behind the bracket;

[0006] The bracket is provided with an atomizing nozzle at the end close to the transmission line, and the bracket can make the atomizing nozzle rotate horizontally in an axial direction, and the atomizing nozzle is arranged to be inclined downward toward the surface of the transmission line;

[0007] An infrared sensor is provided in the channel. The infrared sensor and the atomizing nozzle are electrically connected to an external controller. The output end of the infrared sensor is connected to the input end of the controller, and the input end of the atomizing nozzle is connected to the output end of the controller. The controller is used to receive the signal sent by the infrared sensor to control the opening of the atomizing nozzle.

[0008] The principle of this scheme is: when the paper shell slides out of the channel, the infrared sensor detects a signal, the controller receives the infrared sensor signal and controls the atomizing nozzle to open, thereby spraying water mist toward the upper surface of the paperboard, and each paperboard surface is humidified.

[0009] The beneficial effect of this solution is that before folding, the existing paper shell is easily damaged due to overly dry weather. In this solution, the atomizing nozzle is set at the end of the production line, and the arrival of the paper shell is automatically detected by the infrared sensor. After each paper shell arrives on the transmission line, the atomizing nozzle is turned on to humidify the surface of the paper shell, thereby increasing the humidity of the paperboard.

[0010] Furthermore, the bracket includes a mounting plate, a motor, and a cross bar. The mounting plate is vertically fixed above the tail of the production line. The motor with a horizontal axis is fixed on the mounting plate. The output shaft of the motor is keyed to the cross bar. The atomizing nozzle is fixed on the end of the cross bar away from the tail of the production line. The angle between the atomizing nozzle and the ground can be freely adjusted by the motor.

[0011] Furthermore, a dust removal brush is provided at the top of the channel, and the distance between the lower end of the dust removal brush and the bottom wall of the channel is the thickness of the paper shell, so as to brush off the dust on the surface of the paper shell and prevent the dust from condensing on the surface of the paper shell after subsequent humidification and affecting the flatness of the paper shell.

[0012] Furthermore, the upper end of the dust removal brush is connected to a metal plate, the metal plate is connected to a copper wire, and the end of the copper wire extends out of the channel and connects to the ground, so that the static electricity generated by the friction between the dust removal brush and the surface of the cardboard is guided to the ground.

[0013] Furthermore, a temperature and humidity sensor is provided outside the production line, and the output end of the temperature and humidity sensor is connected to the input end of the controller, and the controller is also used to control the flow rate of the atomizing nozzle according to the temperature and humidity. The external environment is detected to strictly control the humidity of the cardboard.

[0014] Furthermore, the atomizing nozzle and the bracket form a group of humidifying units, and a plurality of groups of humidifying units are arranged at intervals along the width of the transmission line, so as to ensure that the entire width of the transmission line can be covered with water mist, and adapt to paper shells of different specifications.

[0017] The figure marks in the drawings of the specification include: production line 1, transmission line 2, paper shell 3, channel 4, mounting plate 5, motor 6, cross bar 7, through hole 8, atomizing nozzle 9, infrared sensor 10, dust removal brush 11.

[0018] The embodiment is basically as shown in the attached Figure 1 As shown:

[0019] The humidifying device of the packaging paper shell 3 production line 1 includes a bracket located at the rear of the production line 1, and a transmission line 2 that can horizontally transmit the paper shell 3 to be folded is arranged behind the bracket.

[0020] A channel 4 for outputting the packaging paper shell 3 is provided at the tail of the production line 1, and a bracket is located above the channel 4. The bracket includes a vertically arranged mounting plate 5, and a motor 6 with a horizontal axis is fixedly installed on the side wall of the mounting plate 5. The output shaft of the motor 6 is key-connected with a crossbar 7, and a through hole 8 is provided on the crossbar 7 for the output shaft of the motor 6 to pass through. A key slot is provided in the through hole 8, and the crossbar 7 can be key-connected to the output shaft of the motor 6 through the key slot. The adjustment range of the motor 6 is 180°. The angle between the crossbar 7 and the ground can be adjusted by the motor 6.

[0021] A mist nozzle 9 is fixedly mounted on one end of the crossbar 7 away from the motor 6. The mist nozzle 9 is connected to an external water source and an air source through its own interface. The mist nozzle 9 in this embodiment adopts an A-100 air mist nozzle 9, and highly atomized water mist can be sprayed outward through the air mist nozzle 9. The mist nozzle 9 has the function of adjusting the size of the airflow and the size of the flow.

[0022] An infrared sensor 10 is arranged at one end of the channel 4 close to the atomizing nozzle 9, and the probe direction of the infrared sensor 10 is perpendicular to the channel 4 and downward. A dust removal brush 11 is also arranged at one end of the channel 4 close to the atomizing nozzle 9. The distance between the lower end of the dust removal brush 11 and the bottom surface of the channel 4 is the width of the cardboard. The dust removal brush 11 is made of soft brush material. The upper end of the dust removal brush 11 is connected to a metal sheet, and a copper wire is connected to the metal sheet. The other end of the copper wire extends to the ground outside the channel 4. The dust removal brush 11 is grounded through the copper wire, and the static electricity generated by the friction between the dust removal brush 11 and the packaging paper shell 3 is connected to the ground for release.

[0023] Furthermore, in order to accurately control the humidity of the paperboard surface, a temperature and humidity sensor is provided outside the production line 1, and the temperature and humidity sensor is used to obtain the temperature and humidity in the production environment.

[0024] The temperature and humidity sensor, infrared sensor 10, atomizing nozzle 9, and motor 6 are electrically connected to the controller of the peripheral device. When the infrared sensor 10 detects that a cardboard is being transmitted from the channel 4, it sends a signal to the controller, and the controller controls the atomizing nozzle 9 to start, so that the front of the cardboard in the transmission direction can be humidified, and the humidity of the cardboard surface increases under the action of water mist. The controller is also used to adjust the flow rate of the atomizing nozzle 9 according to the temperature and humidity.

[0025] In this embodiment, the mounting plate 5, the motor 6, the cross bar 7, and the atomizing nozzle 9 form a group of humidifying units, and several groups of humidifying units are arranged at intervals along the width of the transmission line 2 to ensure that the water mist range of the atomizing nozzle 9 can cover the entire width of the transmission line 2.

[0026] In order to increase the atomization range of the atomizing nozzle 9, the angle of the atomizing nozzle 9 is adjusted to an acute angle between the atomizing nozzle 9 and the ground.

[0027] The specific implementation process is as follows:

[0028] The cut cardboard is transmitted to the tail of channel 4 of production line 1. When the surface of the cardboard contacts the dust removal brush 11, the dust removal brush 11 cleans the debris on the surface of the cardboard. The static electricity generated by the friction between the dust removal brush 11 and the cardboard is transmitted to the ground through the copper wire. At the same time, when the infrared sensor detects the arrival of the cardboard, it sends a signal to the controller. The controller controls the atomizing nozzle 9 to turn on. The atomizing nozzle 9 sprays water mist obliquely downward. When the cardboard is transmitted from the transmission line 2, the surface contacts the water mist, thereby humidifying the surface of the dry paper shell 3.

[0029] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
