Description

Technical Field

[0001] The present invention relates to an online cooling device for packaging bag film and an installation method thereof, which can not only efficiently and high-quality perform online cooling of packaging bag film, but also is suitable for high-speed production and energy-saving production, and has convenient disassembly and assembly of the cooling bin and good applicability, and belongs to the field of packaging bag production line equipment manufacturing. Background Art

[0002] In the continuous production process of packaging bags, online heat sealing of packaging bag films is the existing mainstream processing method. In order to ensure the subsequent processing quality of the packaging bag films, it is necessary to promptly perform online cooling of the packaging bag films after online heat sealing, that is, to set a cooling station after the heat sealing station in the packaging bag production line.

[0003] There are two mainstream cooling devices currently installed in cooling stations: one is to use cold air blowing to cool the heat-sealed packaging bag film online, such as CN 210149700 U, named "a packaging sealing cooling device", including a frame with a slide bar, a first head and a second head slidably installed on the slide bar, and a driving device driving the first head and the second head to move; the first head includes: a first mounting portion is equipped with a first heating strip and a first seal; the second head includes: a telescopic mechanism and a second seal are installed on the second mounting portion, and the telescopic mechanism is equipped with a second heating strip; the second seal has an air inlet duct inside, and the upper surface of the second seal has multiple air outlet holes, and also includes: a cold air blower, and the air inlet duct is connected to the air outlet of the cold air blower. There are two slide bars, the two slide bars are arranged in parallel, and the two slide bars pass through the two ends of the first mounting portion and the second mounting portion. The driving device comprises: the two ends of the first rotating shaft are rotatably mounted on the two sliding rods, and the rotating shaft is equipped with a connecting rod mechanism; the connecting rod mechanism comprises: a sleeve mounted on the rotating shaft, and two middle rods are relatively mounted on the outer wall of the sleeve, and the two middle rods are rotatably mounted with a connecting rod through the second rotating shaft; it also comprises a transmission part, and the end of one connecting rod is rotatably mounted on the transmission part through the third rotating shaft; the end of the other connecting rod is rotatably mounted on the first mounting part through the fourth rotating shaft; a transmission rod is installed between the transmission part and the second mounting part. The driving device also comprises a driving rod, and the driving rod is rotatably mounted on the frame through a pin shaft, and the rod end of the driving rod is connected to the sleeve through a joint bearing. The first heating strip and the second heating strip are arranged oppositely; the first sealing strip and the second sealing strip are arranged oppositely. The telescopic mechanism is a telescopic cylinder. Its disadvantage is that: this device not only consumes a lot of energy, but also has a low effective utilization rate of cold air cooling, and at the same time, the device cannot cool the packaging bag film with guaranteed quality and quantity during high-speed production.

[0004] The other is to achieve cooling by contacting the cold press plate with the heat-sealed packaging bag film, such as CN 201597202U, named "A cooling device for the hot edge process of an outer packaging bag", which includes a frame, a horizontal support plate is provided in the middle of the frame, and a lifting cooling plate is provided above and below the support plate, and a circulating water channel is installed on the cooling plate. The upper and lower cooling plates are respectively connected to the cylinders installed on the upper and lower ends of the frame. The cross-section of the cooling plate is in the shape of a "convex" character, and the bottom surface of the cooling plate matches the surface of the support plate. The disadvantage is that this device not only has a low cooling efficiency, but also the cooling effect of the cooling plate will not be maintained after a period of cooling work (the cooling plate cools the packaging bag film by absorbing heat, and the temperature of the cooling plate itself will rise after a certain period of work, which will affect the quality of its subsequent cooling of the packaging bag film). Summary of the invention

[0005] Design purpose: In order to avoid the shortcomings of the background technology, an online cooling device for packaging bag film and its installation method are designed, which can not only perform online cooling of packaging bag film with high efficiency and quality, but also is suitable for high-speed production and energy-saving production, and the cooling bin is easy to disassemble and assemble, and has good applicability.

[0006] Design plan: To achieve the above design objectives.

[0007] 1. A first packaging bag film through hole is opened on the front side of the cooling bin, a second packaging bag film through hole is opened on the back side of the cooling bin, and the first packaging bag film through hole and the second packaging bag film through hole are connected to each other; a plurality of supporting roller assemblies are arranged in the bin body of the cooling bin, and the plurality of supporting roller assemblies are located between the first packaging bag film through hole and the second packaging bag film through hole, the bottom surface of the first packaging bag film through hole is lower than the uppermost end of the supporting roller surface in the supporting roller assembly, and the bottom surface of the first packaging bag film through hole is flush with the bottom surface of the second packaging bag film through hole, which is one of the technical features of the present invention. The purpose of such design is: first, when in use, the cooling bin is installed on the cooling station in the packaging bag film production line, and the continuous packaging bag film moves to the cooling station after passing through the previous hot pressing process, and the moving packaging bag film enters the cooling bin through the first packaging bag film through hole, and then flows to the next process after passing through the bin body cavity of the cooling bin and the second packaging bag film through hole in sequence. Since the cold air in the cooling bin exchanges heat with the heat-sealed packaging bag film, the heat-sealed packaging bag film is cooled online uninterruptedly, which not only improves the cooling efficiency of the packaging bag film, but also ensures the cooling quality of the packaging bag film; second, a plurality of supporting roller assemblies are provided in the bin body of the cooling bin and the plurality of supporting roller assemblies are located between the first packaging bag film through hole and the second packaging bag film through hole, so that the plurality of supporting roller assemblies support the moving packaging bag film, thereby avoiding sagging of the packaging bag film (caused by its own weight and gravity) and cold The blowing of cold air in the cooling bin causes the packaging bag film to be scratched against the hole walls of the first packaging bag film through hole and the hole walls of the second packaging bag film through hole; thirdly, the setting of the cooling bin allows the production rate of the packaging bag film to be adjusted within a certain range according to the order quantity, that is, when the order quantity is small, we can reduce the walking speed of the packaging bag film, which can extend the time for the packaging bag film to pass through the cooling bin, that is, extend the cooling time of the packaging bag film. Due to the extension of the cooling time, the set temperature of the cooling bin can be adjusted accordingly, thereby achieving energy-saving production. When the order quantity is large, we can increase the walking speed of the packaging bag film. At this time, since the time for the packaging bag film to pass through the cooling bin is shortened, it is necessary to adjust the cold air output of the cold air blower to ensure that the cooling bin can be relatively stably maintained at a lower temperature setting value, so as to ensure that the cooling bin can cool the heat-sealed packaging bag film online and continuously with quality and quantity during high-speed production.

[0008] 2. The support roller assembly is composed of two bearing seats, two bearings, a support roller and a roller sleeve. A bearing is installed in each of the bearing mounting holes of the two bearing seats. The support roller is installed between the two bearing seats by plugging and matching the through hole of one bearing with one end and the through hole of another bearing with the other end. The roller body of the support roller is provided with a roller sleeve and the roller sleeve is a silicone sleeve, which is the second technical feature of the present invention. The purpose of this design is: first, the support roller assembly is a driven assembly, so that the energy consumption can be reduced while ensuring that the support roller can rotate flexibly; second, because the roller sleeve is a silicone sleeve, the support roller can take away the heat on the packaging bag film during the contact with the traveling packaging bag film, thereby accelerating the cooling of the packaging bag film; third, the silicone sleeve is soft in texture, and the silicone sleeve will not scratch the packaging bag film during the contact between the two, especially in high-speed production.

[0009] 3. A first temperature sensor is provided on one side wall of the cooling bin, and a second temperature sensor is provided on the other side wall. The first temperature sensor and the second temperature sensor are respectively located in the middle of their respective walls, which is the third technical feature of the present invention. The purpose of such a design is that the controller determines the current temperature in the cooling bin based on the last real-time data of the first temperature sensor and the second temperature sensor, and performs compensation control based on the difference between the current temperature and the set temperature. When the controller determines that the current temperature value is less than the set temperature value, the controller will control the cold air fan to reduce the output of cold air to reduce energy consumption. When the controller determines that the current temperature value is greater than the set temperature value, the controller will control the cold air fan to increase the output of cold air, ensuring that the cooling bin can effectively cool the heat-sealed packaging bag film with guaranteed quality and quantity, that is, energy-saving production is carried out under the premise of ensuring production quality.

[0010] 4. The design of providing a camera and a lighting lamp on the inner top surface of the cooling bin is the fourth technical feature of the present invention. The purpose of this design is that the camera and the lighting lamp are provided on the inner top surface of the cooling bin so that the staff can observe the working conditions inside the cooling bin in real time.

[0011] 5. The upper end surface of the panel in the base frame is horizontally provided with two grooves and a mold lifter is installed in each of the two grooves. The upper end surface of the panel in the base frame is horizontally provided with a strip bolt through hole and the strip bolt through hole passes through the upper and lower end surfaces of the panel. The strip bolt through hole is located between the two grooves and the strip bolt through hole and the groove are arranged in parallel. After the cooling bin is moved to the specified position of the upper end surface of the base frame by the mold lifter, two fixing blocks are used to fix the cooling bin to the upper end of the base frame. The lower end surface of the fixing block is provided with a threaded hole and a bolt is screwed into the threaded hole. This is the fifth technical feature of the present invention. The purpose of such design is: during installation, a row of rollers on the mold lifter are lifted upward so that the upper ends of the rollers are higher than the upper end surface of the base frame; then the cooling bin is moved to the upper end of the base frame from one side of the base frame and the cooling bin is moved to the specified position of the upper end surface of the base frame through a row of rollers, and then the row of rollers on the mold lifter are dropped back downward, and at this time the bottom surface of the cooling bin is in contact with the upper end surface of the base frame; then two fixing blocks are placed on both sides of the cooling bin, and then the two fixing blocks are fixed to the base frame by a bolt respectively; then one end of the pipe is fixedly connected to the air outlet of the air cooler, and the other end is fixedly connected to the air inlet of the cooling bin; when disassembly is required, the two bolts are unscrewed and the two fixing blocks are removed, and then the row of rollers on the mold lifter are lifted upward so that the cooling bin is lifted up, and then the cooling bin is moved out of the base frame along the rollers, so as to realize quick and labor-saving disassembly and assembly of the cooling bin.

[0012] 6. The outer wall surfaces on both sides of the cooling bin are respectively provided with a convex strip in the longitudinal direction, a slot is provided on one side of the fixing block and the slot passes through the upper and lower end surfaces of the fixing block, and the fixing block is fixed to the chassis by bolts after the two slots are matched with the corresponding convex strips. This design is the sixth technical feature of the present invention. The purpose of this design is that the outer wall surfaces on both sides of the cooling bin are respectively provided with a convex strip in the longitudinal direction, a slot is provided on one side of the fixing block and the slot passes through the upper and lower end surfaces of the fixing block, and the fixing block is fixed to the chassis by bolts after the two slots are matched with the corresponding convex strips. In this way, the fixing block can limit the cooling bin in the horizontal plane in all directions, including front, back, left and right.

[0013] 7. The design of an exhaust fan at the air outlet of the cooling bin is the seventh technical feature of the present invention. The purpose of this design is that when the order volume is large, the production can be increased by increasing the speed of the packaging bag film. Since the speed is increased, the time for the packaging bag film to pass through the cooling bin is shortened. At this time, the through hole adjusts the cold air output of the air cooler, and at the same time, by turning on the exhaust fan (the use of the exhaust fan can make the hot air in the cooling bin be extracted in time), it is ensured that the cooling bin can be relatively stably maintained at a lower temperature setting value, and the temperature in the cooling bin can be quickly adjusted to ensure that the cooling bin can always cool the heat-sealed packaging bag film online and uninterruptedly in high-speed production with guaranteed quality and quantity.

[0014] 8. The cooling bin includes an inner shell and an outer shell, and a plurality of fixed-distance connecting columns are provided between the outer wall surface of the inner shell and the inner wall surface of the outer shell, and the gap between the outer wall surface of the inner shell and the inner wall surface of the outer shell is filled with thermal insulation material, which is the eighth technical feature of the present invention. The purpose of such design is: first, a thermal insulation layer is provided between the inner shell and the outer shell, which can greatly reduce the heat exchange between the cold air in the cooling bin and the outside through the bin shell, thereby reducing the energy consumption of the cooling bin; second, a plurality of fixed-distance connecting columns are provided between the outer wall surface of the inner shell and the inner wall surface of the outer shell, and the fixed-distance connecting columns not only play a role in connecting and supporting the inner shell and the outer shell, but also can ensure that the thickness of the thermal insulation layer is consistent everywhere, thereby improving the thermal insulation effect of the thermal insulation layer.

[0015] 9. A brush assembly is respectively provided on the front and back of the cooling bin, wherein one brush assembly is located at the through hole of the first packaging bag film and the other brush assembly is located at the through hole of the second packaging bag film. This design is the ninth technical feature of the present invention.

[0031] A first temperature sensor 5 is provided on one side wall of the cooling bin 3, and a second temperature sensor 6 is provided on the other side wall. The first temperature sensor 5 and the second temperature sensor 6 are respectively located in the middle of their respective walls. A controller is also included. The signal output end of the first temperature sensor 5 and the signal output end of the second temperature sensor 6 are respectively connected to the signal input end of the controller through a data line. The controller can control the start and stop of the exhaust fan 11 and the size of the air volume. The exhaust fan 11 is an adjustable air volume fan. The adjustable air volume fan is a prior art, so it will not be described here. An inspection door is provided on the upper end face of the cooling bin 3. A camera 7 and a lighting lamp 8 are provided on the inner top face of the cooling bin 3. The setting of the camera 7 enables the staff to observe the working conditions inside the cooling bin 3 in real time.

[0032] The upper end surface of the panel in the base frame 2 is provided with two grooves 21 in the horizontal direction, and a mold lifter 22 is installed in each of the two grooves 21. The upper end surface of the panel in the base frame 2 is provided with a strip bolt through hole 23 in the horizontal direction, and the strip bolt through hole 23 passes through the upper and lower end surfaces of the panel.

The lower end surface of the fixing block 9 is provided with a threaded hole 91, and a bolt 10 is screwed into the threaded hole 91. A convex strip 35 is longitudinally provided on the outer wall surfaces of both sides of the cooling bin 3, and a slot 92 is provided on one side of the fixing block 9, and the slot 92 passes through the upper and lower end surfaces of the fixing block. After the two slots 92 are matched with the corresponding convex strip 35, the fixing block 9 is fixed to the base frame 2 by bolts 10.

[0033] The exhaust fan 11 is provided at the air outlet 32 ​​of the cooling bin 3, and the exhaust fan 11 can be turned on, off and the output air volume can be adjusted as needed. The cooling bin 3 includes an inner shell 36 and an outer shell 37, and a plurality of fixed-distance connecting columns are provided between the outer wall surface of the inner shell 36 and the inner wall surface of the outer shell 37, and the gap between the outer wall surface of the inner shell 36 and the inner wall surface of the outer shell 37 is filled with a heat-insulating material, and the heat-insulating material is a heat-insulating cotton.

[0034] When in use, the cooling bin 3 is installed on the cooling station in the packaging bag film production line. The continuous packaging bag film (the packaging bag film is continuous during the bag making process, and the packaging bag is cut at the end station of the production line) moves to the cooling station after passing through the previous hot pressing process. The moving packaging bag film enters the cooling bin 3 through the first packaging bag film through hole 33, and then flows to the next process after passing through the bin body cavity of the cooling bin 3 and the second packaging bag film through hole 34 in turn; the controller determines the current temperature in the cooling bin 3 according to the real-time data of the first temperature sensor 5 and the second temperature sensor 6, and performs compensation control according to the difference between the current temperature and the set temperature. The controller can use the average value of the current measured value of the first temperature sensor 5 and the current measured value of the second temperature sensor 6 as the current temperature value of the current cooling bin 3; when the controller determines that the current temperature value is less than the set temperature value (that is, the temperature in the cooling bin 3 is lower than the set temperature), the controller will control the air cooler 1 to reduce the output of the cold air to achieve the purpose of reducing energy consumption. When the controller determines that the current temperature value is greater than the set temperature value (that is, the cooling When the temperature in the cooling bin 3 is higher than the set temperature), the controller will control the cooling fan 1 to increase the output of cold air to ensure that the cooling bin 3 can effectively cool the heat-sealed packaging bag film with guaranteed quality and quantity; in addition, the setting of the cooling bin 3 allows the production rate of the packaging bag film to be adjusted within a certain range according to the order quantity, that is, when the order quantity is small, we can reduce the walking speed of the packaging bag film, which can extend the time for the packaging bag film to pass through the cooling bin 3, that is, extend the cooling time of the packaging bag film. Due to the extension of the cooling time, the set temperature of the cooling bin 3 can be adjusted accordingly, thereby achieving energy-saving production. When the order quantity is large, we can increase the walking speed of the packaging bag film. At this time, since the time for the packaging bag film to pass through the cooling bin 3 is shortened, it is necessary to adjust the cold air output of the cooling fan 1. At the same time, the controller also controls the exhaust fan 11 to work to ensure that the hot air in the cooling bin 3 is extracted in time, and to ensure that the cooling bin can be relatively stably maintained at a lower temperature setting value, so as to ensure that the cooling bin 3 can cool the heat-sealed packaging bag film online and uninterruptedly with guaranteed quality and quantity during high-speed production.

At this time, the soft brush head of the brush plate 121 is in contact with the packaging bag film passing through the cooling station. Since the screw through hole 124 is a strip through hole, that is, the height of the brush plate 121 is adjustable, the brush plate 121 can better contact and remove dust from packaging bag films of different thicknesses, thereby improving the applicability of the device. At the same time, the shielding of the brush plate 121 can further reduce the overflow of cold air from the first packaging bag film through hole 33 and the second packaging bag film through hole 34.
