Description

Technical Field

[0001] The utility model relates to the technical field of melt-blown spinning, in particular to a double-row hot-melt adhesive film melt-blown spinning plate. Background Art

[0002] Hot melt adhesive film is a thin film adhesive material formed by fully extending hot melt adhesive. It is widely used in bonding common materials such as fabrics, paper, polymer materials and metals. The hot melt adhesive film meltblown spinning plate is a key component for producing low melting point polyurethane hot melt adhesive webs. The function of the meltblown spinning plate is to transform the viscous polymer melt or solution into a thin stream with a specific cross-section through micropores, and solidify it through a coagulation medium such as air or a coagulation bath to form filaments.

[0003] The meltblown spinning plate is affected by temperature during spinning, and its viscosity is very sensitive to temperature changes. The processing environment is demanding. During the meltblown spinning process, the plate is prone to sticking, so the meltblown spinning plate needs to be cleaned to avoid affecting the discharging of the meltblown spinning plate. At the same time, since the discharging plate in the meltblown spinning plate is generally fixed with multiple bolts or welding, the disassembly is cumbersome. When the plate sticks during the meltblown spinning process, it is inconvenient to disassemble and clean the spinneret, resulting in low spinning efficiency of the device, which is not conducive to meltblown spinning. Therefore, in order to solve the above problems, we need to design a double-row hot melt adhesive film meltblown spinning plate. Utility Model Content

[0025] The spinning mechanism 100 includes a box body 101, a feed port 102 is arranged on the top of the box body 101, a discharge pipe 103 is fixedly connected to the bottom of the box body 101, a spinneret 104 is arranged at the bottom of the discharge pipe 103, a motor assembly 110 is arranged in the inner cavity of the box body 101, a stirring assembly 120 is arranged on the motor assembly 110, a filter assembly 130 is arranged in the discharge pipe 103, a vibration assembly 140 is arranged on the filter assembly 130, and a fixing assembly 150 is arranged on the outer side of the discharge pipe 103.

[0026] Specifically, the motor assembly 110 works so that the stirring assembly 120 stirs the raw materials in the inner cavity of the box body 101 to mix them evenly, and at the same time conducts heat to avoid cooling of part of the raw materials, which is inconvenient for melt-blowing spinning; through the filtering assembly 130, part of the cooled raw materials can be filtered to the top of the filtering assembly 130, and the heat is made uniform through the stirring assembly 120. Furthermore, through the vibration assembly 140, the filtering assembly 130 is vibrated to facilitate filtering and discharging of the material; through the fixing assembly 150, the spinneret 104 can be disassembled to facilitate cleaning of the spinneret 104 to avoid spinning sticking to the plate and affecting the operation of the device.

[0027] See also Figure 1-Figure 3 The motor assembly 110 includes a motor 110a, a rotating shaft 110b, a bottom plate 110c and a side plate 110d. The rotating shaft 110b is fixedly connected to the bottom of the motor 110a. The motor 110a is fixedly connected to the top of the box 101. The bottom plate 110c is fixedly connected to the rotating shaft 110b. The side plates 110d are fixedly connected to both sides of the top of the bottom plate 110c. The stirring assembly 120 includes a heat-conducting rotating plate 120a and a heat-conducting stirring rod 120b. The heat-conducting rotating plate 120a is fixedly connected to the rotating shaft 110b. The heat-conducting stirring rod 120b is fixedly connected to the heat-conducting rotating plate 120a.

[0028] Specifically, by operating the motor 110a, the rotating shaft 110b drives the heat-conducting rotating plate 120a to rotate, which can cause the heat-conducting stirring rod 120b to rotate, thereby facilitating the mixing of the raw materials. At the same time, the heat is conducted through the heat-conducting rotating plate 120a to avoid cooling of the raw materials and inconvenience in melt-blowing; further, through the bottom plate 110c and the side plate 110d, part of the raw materials can be prevented from sticking to the side wall or bottom of the inner cavity of the box body 101, causing waste of raw materials.

[0029] See also Figure 2-Figure 5 The filter assembly 130 includes a filter plate 130a, a housing 130b, a first spring 130c and a protective plate 130d. A fixed groove 103b is provided in the inner cavity of the discharge pipe 103, an inner groove 130e is provided in the inner cavity of the housing 130b, one end of the first spring 130c is fixedly connected to the bottom of the filter plate 130a, the other end of the first spring 130c is fixedly connected to the bottom of the inner groove 130e, and the protective plate 130d is fixedly connected to the bottom of the filter plate 130a.

The boss 140a is fixedly connected to the filter plate 130a, and the fixed rod 140b is fixedly connected to the boss 140a.

[0030] Specifically, part of the cooled raw material can be filtered to the top of the filter plate 130a through the filter plate 130a to avoid affecting the spinning of the spinneret 104; further, when the rotating shaft 110b rotates, the fixed rod 140b can be moved downward through the inclined groove 140d, thereby driving the first spring 130c to be compressed, and then the filter plate 130a can be vibrated to facilitate faster filtering.

[0031] See also Figure 1-Figure 3 and Figure 5 The fixing assembly 150 includes a pull rod 150a, a second spring 150b, a movable plate 150c and a fixed column 150d. A through slot 103a is provided on the discharge pipe 103. One end of the pull rod 150a is fixedly connected to one side of the movable plate 150c. One end of the fixed column 150d is fixedly connected to the other side of the movable plate 150c. One end of the second spring 150b is fixedly connected to the inner wall of the through slot 103a. The other end of the second spring 150b is fixedly connected to one side of the movable plate 150c. A fixed plate 104a is fixedly connected to the top of the spinneret 104.

[0032] Specifically, when the ejected spun yarn sticks to the spinneret 104 and is inconvenient to clean, the pull rod 150a is pulled to move the movable plate 150c and drive the fixed column 150d to move and separate from the fixed plate 104a, thereby facilitating the disassembly of the spinneret 104 and cleaning it, thereby avoiding the spun yarn sticking to the plate and affecting the operation of the device.
