Description

Technical Field

[0001] The invention relates to the field of industrial production, in particular to a moisturizing system for a film blowing machine workshop. Background Art

[0002] A blown film machine melts polyethylene granules and other materials, blowing the molten material out of the die head to produce polyethylene film. The temperature of the molten material is generally around 180-190°C, and the extruded film bubble typically reaches a temperature of around 150°C. Research has shown that maintaining a high humidity during polyethylene film production can improve the film's performance. For example, the oxygen transmission rate of films produced at 50% humidity is over 60% lower than that of single-layer films made from thermoplastic, low-alcoholysis polyvinyl alcohol (PVA) of the same composition, produced by cast or blown film.

[0003] At present, in film blowing machine workshops, fans or other air circulation systems are often needed to cool down the extruded high-temperature film bubbles. At the same time, due to the high temperature of the film bubbles themselves, some of the moisture in the air will be taken away during the cooling process, causing the air humidity in the workshop to continue to decrease, which is not conducive to ensuring the performance of the produced film.

[0004] Therefore, there is an urgent need for a moisturizing system for film blowing machine workshops to keep the air humidity in the workshop within a reasonable range and ensure the excellent performance of the produced film. Summary of the Invention

DETAILED DESCRIPTION

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] One of the purposes of the present invention is to provide a moisturizing system for a film blowing machine workshop to solve the problem in existing film blowing machine workshops that the air humidity in the workshop continuously decreases due to the high bubble temperature, which is not conducive to ensuring the performance of the produced film.

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0034] Example 1

[0035] like Figure 1-Figure 3 As shown, this embodiment provides a film blowing machine workshop moisturizing system 100, which mainly includes a water source 1, an atomizer 2 and a nozzle 4. The atomizer 2 is connected to the water source 1 through an atomizing pipe 3, and the atomizer 2 is used to atomize the water from the water source 1; the nozzle 4 is connected to the atomizer 2 through a spray pipe 5 to spray the water mist atomized by the atomizer 2 into the film blowing machine workshop 7, thereby achieving the effect of moisturizing the workshop.

[0036] In this embodiment, the water source 1 can directly use a tap water source, such as a water pipe, and the atomizing pipe 3 can be directly connected to the faucet of the tap water pipe. In addition, the water source 1 can also be a water storage structure composed of a water tank and a water pump, wherein a sufficient amount of water is pre-stored in the water tank, the water pump is connected to the water tank, and the atomizer 2 is connected to the water pump via the atomizing pipe 3. When the water pump is turned on, the water in the water tank can be pumped into the atomizer 2 via the atomizing pipe 3. As a preferred embodiment, the water source 1 of this embodiment uses a tap water source located outside the film blowing machine workshop 7, the atomizer 2, the spray pipe 5 and the nozzle 4 are all located inside the film blowing machine workshop 7, and the atomizing pipe 3 passes through the side wall 71 of the film blowing machine workshop 7 and connects to the external water source 1.

[0037] Furthermore, in this embodiment, to ensure the quality of the produced film, the tap water needs to be purified. A water processor 6 can be provided on the atomization pipeline 3 to treat the tap water into pure water. The water processor 6 can be any existing purifier structure. The tap water is treated by the water processor 6 before being discharged into the atomizer 2.

[0038] In this embodiment, Figure 1-Figure 3As shown, the spray pipeline 5 includes a main spray line 51 and a branch spray line 52. The inlet of the main spray line 51 is connected to the atomizer 2. The main spray line 51 is connected to a plurality of branch spray lines 52 at intervals along its length. The main spray line 51 and the branch spray lines 52 are both arranged above the film blowing machine 8 in the film blowing machine workshop 7. A plurality of nozzles 4 are provided on any branch spray line 52. As a preferred solution, Figure 2 As shown, the atomizer 2 is located on the floor of the film blowing machine workshop 7 and is installed near the side wall 71 of the film blowing machine workshop 7. The spray main line 51 is an "L"-shaped main line. The short end of the "L"-shaped main line is connected to the atomizer 2. The long side of the "L"-shaped main line is located above the film blowing machine 8, and the length direction of the long side is arranged along the arrangement direction of the film blowing machines 8 in the film blowing machine workshop 7. Generally, 2 to 5 film blowing machines 8 are arranged at intervals in the film blowing machine workshop 7. The long side of the "L"-shaped main line can basically cover all film blowing machines 8. In actual operation, the long side of the "L"-shaped main line can be fixed to the ceiling of the film blowing machine workshop 7 using fixings such as pipe clamps.

[0039] In this embodiment, multiple groups of spray branch pairs are arranged at intervals along the length of the long side of the "L"-shaped main pipeline. The spray branch pairs are arranged one-to-one with the film blowing machines 8, that is, a group of spray branch pairs is arranged above each film blowing machine 8. Any group of spray branch pairs includes two spray branches arranged symmetrically on both sides of the long side pipeline. Figure 1 and Figure 2 As shown, three film blowing machines 8 are spaced apart in the film blowing workshop 7. Accordingly, three sets of spray branch pairs are spaced apart on the long side pipes. In practice, to ensure uniform humidity in the film blowing workshop 7, the long side pipes can be arranged at the center line of the ceiling of the film blowing workshop 7.

[0040] In this embodiment, a valve 9 is provided at one end of any spray branch 52 close to the long side pipeline. The valve 9 is preferably an electrically controlled intercepting valve for controlling the connection and disconnection between the spray branch 52 and the long side pipeline.

[0041] In this embodiment, a negative pressure fan 10 is installed on each long side pipe between any two adjacent pairs of spray branches. The negative pressure fan 10 is installed inside the long side pipe and is a waterproof fan. It is used to suck in the water mist that enters the long side pipe, facilitating its better discharge. At the same time, since the water mist easily condenses on the inner wall of the long side pipe after entering, the condensed water can be dispersed again when passing through the negative pressure fan 10, which helps to improve the atomization effect of the humidification system.

[0042] In this embodiment, it also includes a control system 11, a humidity sensor 12 and a signal sensor 13. The humidity sensor 12 is arranged on the periphery of the film blowing machine 8 and is used to detect the air humidity around the film blowing machine 8. The signal sensor 13 is arranged on the spray branch 52. The signal sensor 13 is communicatively connected to the valve 9; the humidity sensor 12, the signal sensor 13, the atomizer 2 and the negative pressure fan 10 are all communicatively connected to the control system 11.

[0043] In this embodiment, the nozzle 4 includes a conical shell 41, the large end of the conical shell 41 is closed, and the small end is provided with a threaded head 42 for connecting to the spray pipe 5; a plurality of mist outlets 43 are provided on the side wall and the end plate of the large end of the conical shell 41. The water mist can be sprayed out through the multi-directional mist outlets 43 in the nozzle 4 at the same time, which is conducive to uniform humidification. At the same time, a threaded head 42 is provided on the top (small end) of the conical shell 41, and a threaded hole matching the threaded head 42 is provided on the spray branch 52. The conical shell 41 can be screwed onto the spray branch 52 through the threaded head 42, and a through hole is provided in the threaded head 42 to connect the spray branch 52 and the conical shell 41. The above-mentioned threaded connection method is adopted between the nozzle 4 and the spray branch 52, which can facilitate the disassembly and assembly between the nozzle 4 and the spray branch 52. When a nozzle 4 is blocked or a section of the spray branch 52 fails, the nozzle 4 can be replaced in time, or the nozzle 4 can be removed to repair the corresponding spray branch 52.

[0044] The following takes the example of three film blowing machines 8 arranged at intervals in a film blowing machine workshop 7 to specifically illustrate the operating principle of the film blowing machine workshop moisturizing system 100.

[0045] A water treatment unit 6 is installed on the spray pipe 5 outside the film blowing machine workshop 7. The water treatment unit 6 processes tap water into pure water and then discharges it into the atomizer 2. The atomizer 2 atomizes the pure water. The atomized water mist flows along the main spray pipe 51 to each spray branch 52. The spray branch 52 is equipped with multiple nozzles 4, and water mist is sprayed through the nozzles 4 to humidify the film blowing machine workshop 7. At the same time, a valve 9 and a signal sensor 13 are installed on each spray branch 52. The signal sensor 13 is preferably wirelessly connected to the control system 11. Because the three film blowing machines 8 in the film blowing machine workshop 7 may adopt an intermittent operation mode, due to machine maintenance or other reasons, only one or two film blowing machines 8 may be in operation. Therefore, according to the operating status of the three film blowing machines 8, the control system 11 can send a command to the signal sensor 13 to close the valve 9 on the spray branch 52 corresponding to the non-operating film blowing machine. In this way, water mist is sprayed only from the nozzles 4 on the other spray branches 52, thereby achieving energy saving. At the same time, the control system 11 can also control whether the negative pressure fan 10 is operating based on the position of the active film blowing machine. For example, when the film blowing machines 8 in the last two rows are not operating and only the film blowing machine 8 near the atomizer 2 is operating, all negative pressure fans 10 and the valves 9 on the last two groups (rows) of spray branches 52 can be closed. In this solution, one or more humidity sensors 12 are preferably installed at the top and bottom of each film blowing machine 8 to transmit the humidity around the film blowing machine 8 to the control system 11 in real time. The operator can adjust the atomization gear of the atomizer 2 in real time based on the detected humidity, appropriately increasing or decreasing the spray output. Under normal circumstances, the humidity around the film blowing machine 8 is maintained at 50%-80%.

[0046] In actual operation, the number of spray branch pairs on the long side pipeline can be increased according to the increase in the number of film blowing machines 8, so that the humidification system covers all film blowing machines 8 in the workshop.

[0047] It should be noted that it is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.
