Description

Technical Field

[0001] This utility model relates to the field of core production equipment technology, and in particular to a device for targeted application of absorbent core polymers. Background Technology

[0002] In the composite production of cores for disposable hygiene products such as baby diapers and adult diapers, polymers (superabsorbent polymer / SAP) are key raw materials, and their precise and uniform distribution directly affects the product's absorption rate and absorption capacity. Existing polymer application devices typically use a dispersion method to spray the polymer onto the composite core. However, this method often suffers from problems such as non-targeting, uneven application, material waste, and reduced production efficiency.

[0003] Based on the above, in the prior art, patent application number CN201910306466.7 discloses a mechanism for the targeted application of absorbent polymers to the core material of hygiene products. The mechanism includes a frame and a transfer roller. One side of the frame is fixedly connected to the back of the transfer roller. A groove is formed on the outer surface of the transfer roller, and a hopper is connected to the top of the transfer roller. The top of the hopper penetrates the frame and extends to the top of the frame. Six guide rollers are arranged inside the frame and around the outer ring of the transfer roller, connected by a conveyor belt. This mechanism performs targeted application of absorbent polymers on a core material compounding machine. The powder effectively controls the spreading area and surface area of ​​superabsorbent polymer (SAP) raw materials, reducing the amount of polymer used. Simultaneously, the mechanism employs fixed-length, fixed-position, and quantitative powder spreading, ensuring stable and continuous production of the core material in the subsequent bonding process and preventing leakage of the superabsorbent polymer raw materials. The superabsorbent polymer is transferred at a fixed point through grooves on the surface of the transfer roller, while the tarpaulin is conveyed by guide rollers and a conveyor belt. When the superabsorbent polymer and tarpaulin rotate around the transfer roller to the lower position, the superabsorbent polymer detaches from the grooves of the transfer roller using its own gravity and smoothly transfers to the surface of the tarpaulin, achieving the fixed-point powder spreading process.

[0004] However, although the device employs a fixed-length, fixed-position, and quantitative powder application technology to ensure stable and continuous production of the core material in the subsequent bonding process and to prevent leakage of the absorbent polymer raw material, some shortcomings still exist in practical applications. Specifically, when the absorbent polymer enters the groove on the surface of the transfer roller from the hopper, although it can fill the groove, the polymer particles often cannot be stably fixed in the groove during the rotation of the transfer roller, posing a risk of premature falling off. This results in differences in the amount of absorbent polymer applied at each fixed application point, thus affecting the uniform application of the polymer on the absorbent core. Utility Model Content

[0005] To address the technical deficiencies in the background art, this utility model proposes a targeted dispensing device for absorbent core polymers. To further solve the aforementioned technical problems and meet practical needs, the specific technical solution is as follows:

[0006] A device for targeted application of absorbent core polymers includes a storage hopper, an application assembly, and a fixing frame. The storage hopper is located on top of the application assembly and communicates with the interior of the application assembly. The fixing frame is connected to one side of the application assembly. The application assembly includes an application roller and an application seat. The application seat is located on one side of the application roller and fits against the circumferential surface of the application roller. An arc-shaped discharge channel is provided between the application seat and the circumferential surface of the application roller. A drive shaft is sleeved inside the application roller and is fixedly connected to the application roller. A fixing sleeve is sleeved on the outside of the end of the drive shaft away from the application roller and is rotatably connected to the application roller. A drive motor is connected to the end of the drive shaft away from the fixing sleeve. A plurality of axially extending application grooves are equidistantly arranged on the circumferential surface of the application roller, and the application grooves are rotationally symmetrically distributed on the circumferential surface of the application roller.

[0007] Furthermore, a connecting square tube and an mounting plate are provided below the storage hopper. The inlet end of the connecting square tube is connected to the outlet end of the storage hopper, and the outlet end of the connecting square tube is connected to the mounting plate. The mounting plate surrounds and is connected to the edge of the outlet end of the connecting square tube.

[0008] Furthermore, a feeding channel is provided through the top right side of the broadcasting seat, and the discharge end of the connecting square tube is installed at the corresponding position of the feeding channel and communicates with the feeding channel. The four corners of the mounting plate are provided with first fixing members, which longitudinally penetrate the mounting plate and the top of the broadcasting seat. The feeding channel is connected to the discharge channel.

[0009] Furthermore, the discharge channel is provided with a spreading port below the spreading roller, and the discharge channel is provided with an inwardly extending inclined surface at the spreading port position. The height of the discharge channel where the inclined surface is located gradually decreases along the material movement direction and toward the spreading port.

[0010] Furthermore, the fixed sleeve has a fixed ring fixedly connected to the circumferential surface of the end near the drive motor. The fixed ring has a fixed hole axially extending through its side. The fixed holes are distributed rotationally symmetrically on the side of the fixed ring. A first bearing is installed inside the fixed sleeve at the corresponding position of the fixed ring. The first bearing supports and allows the drive shaft to rotate inside the fixed sleeve.

[0011] Furthermore, the end of the drive shaft away from the drive motor is axially disposed inside the spreading roller. An installation channel is axially provided inside the spreading roller. The shape and size of the installation channel match the end of the drive shaft away from the drive motor. Several second fixing members are provided on the side of the spreading roller away from the drive motor in a rotationally symmetrical manner. One end of the second fixing member axially penetrates the spreading roller and is fixedly placed inside the drive shaft. Second bearings are respectively sleeved on both ends of the spreading roller, and the second bearings are installed between the spreading seat and the spreading roller.

[0012] Furthermore, the fixing frame includes a horizontal plate, a vertical plate, and a reinforcing plate. The horizontal plate and the vertical plate are perpendicular to each other and their ends are connected to each other. The reinforcing plate is disposed on the intersecting vertical plane of the horizontal plate and the vertical plate and is connected to the horizontal plate and the vertical plate respectively. The horizontal plate is connected to the side of the spreading seat. The surface of the vertical plate has mounting holes symmetrically arranged on the upper and lower sides of the reinforcing plate.

[0013] The beneficial effects of this utility model are as follows:

[0014] This invention achieves continuous and uniform spreading of polymer materials through a spreading roller, a spreading seat, and an arc-shaped discharge channel. The spreading grooves on the spreading roller can store a certain amount of polymer. When the spreading roller rotates, the polymer in the grooves is spread out in a fixed-point and quantitative manner, while the polymer in the feeding channel is continuously and uniformly spread on the core surface, thereby enabling precise quantitative and positioning spreading of polymer on the core. The fixing frame can stably install the spreading seat in the required position. The connection structure formed by the horizontal plate, vertical plate, and reinforcing plate of the fixing frame can enhance the overall stability and load-bearing capacity of the fixing frame. The spreading grooves are rotationally symmetrically distributed on the circumferential surface of the spreading roller, and are matched with the rotation speed of the spreading roller to meet different spreading requirements.

[0021] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0022] like Figures 1 to 5 As shown, this utility model provides a technical solution: a device for targeted application of absorbent core polymer, comprising a storage hopper 1, an application assembly 2, and a fixing frame 3. The storage hopper 1 is disposed on top of the application assembly 2 and communicates with the interior of the application assembly 2. The fixing frame 3 is connected to one side of the application assembly 2. The application assembly 2 includes an application roller 22 and an application seat 21. The application seat 21 is disposed on one side of the application roller 22 and fits against the circumferential surface of the application roller 22. An arc-shaped space is provided between the application seat 21 and the circumferential surface of the application roller 22. The discharge channel 28 has a drive shaft 23 sleeved inside the spreading roller 22. The drive shaft 23 is fixedly connected to the spreading roller 22. A fixed sleeve 24 is sleeved on the outside of the end of the drive shaft 23 away from the spreading roller 22. The fixed sleeve 24 is rotatably connected to the spreading roller 22. A drive motor 26 is connected to the end of the drive shaft 23 away from the fixed sleeve 24. A plurality of spreading grooves 221 extending axially are equidistantly arranged on the circumferential surface of the spreading roller 22. The spreading grooves 221 are rotationally symmetrically distributed on the circumferential surface of the spreading roller 22.

[0023] Polymer material enters the spreading assembly 2 through the storage hopper 1. Part of it enters the spreading trough 221 directly, while the other part is continuously supplied through the feed channel 211 and the discharge channel 28. The rotation of the spreading roller 22 causes the polymer material in the spreading trough 221 to be spread out in a fixed-point, quantitative manner, forming the reinforcing layer 42. Meanwhile, the polymer material in the feed channel 211 is continuously and evenly spread onto the surface of the core 4, forming the basic spreading layer 41. This combination of continuous and fixed-point spreading ensures both the uniform distribution of the polymer material and the effect of fixed-point reinforcement. The spreading trough 221 has a short length. The height of the discharge channel 28 ensures full utilization of the polymer material during the spreading process. The rotation speed of the spreading roller 22 and the number and size of the spreading grooves 221 can be adjusted according to actual needs to further improve the spreading efficiency of the polymer material. The fixing sleeve 24 is used to fix the spreading roller 22 through the drive shaft 23, and the fixing frame 3 is used to fix the spreading seat 21, so that the spreading assembly 2 can be easily installed to adapt to different production needs. The fixed connection between the spreading roller 22 and the drive shaft 23 and the setting of the second fixing part 29 ensure the stability and reliability of the spreading process.

[0024] As a technical explanation, such as Figure 5 As shown, the spreading effect that the polymer fixed-point spreading device of this utility model can achieve is as follows: a uniform polymer layer is continuously applied to the surface of the core 4 to form a basic spreading layer 41, and then a polymer layer is applied at fixed points and in fixed quantities at intervals on the surface of the basic spreading layer 41 to form a reinforcing layer 42 with intervals on the surface of the basic spreading layer 41.

[0025] As one of the preferred embodiments of this utility model, such as Figures 1 to 3 As shown, a connecting square tube 13 and an mounting plate 11 are provided below the storage hopper 1. The inlet end of the connecting square tube 13 is connected to the outlet end of the storage hopper 1, and the outlet end of the connecting square tube 13 is connected to the mounting plate 11. The mounting plate 11 surrounds and connects to the edge of the outlet end of the connecting square tube 13.

[0026] The storage hopper 1, serving as a storage and supply component for polymer materials, is designed to be located at the top of the spreading assembly 2 and maintain communication with the interior of the spreading assembly 2. This ensures that the polymer materials can smoothly enter the spreading assembly 2 for subsequent spreading operations. The inlet end of the connecting square tube 13 is connected to the outlet end of the storage hopper 1, and the outlet end of the connecting square tube 13 is connected to the mounting plate 11. The main function of the mounting plate 11 is to enclose and connect to the edge of the outlet end of the connecting square tube 13, allowing the storage hopper 1 to be mounted on the spreading base 21 via the mounting plate 11 and the first fixing member 12. At the material channel 211 location, a feeding channel 211 is provided through the top right side of the spreading base 21. The feeding channel 211 corresponds to and is connected to the discharge end of the connecting square tube 13. The polymer material can then enter the feeding channel 211 of the spreading base 21 from the storage hopper 1 through the connecting square tube 13, preparing for subsequent spreading operations. At the same time, to ensure a stable connection between the mounting plate 11 and the spreading base 21, a first fixing member 12 is used to longitudinally penetrate the top of the mounting plate 11 and the spreading base 21, fixing the mounting plate 11 to the top of the spreading base 21.

[0027] As one of the preferred embodiments of this utility model, such as Figures 1 to 3 As shown, a feeding channel 211 is provided through the top right side of the broadcasting base 21. The discharge end of the connecting square tube 13 is installed at the corresponding position of the feeding channel 211 and communicates with the feeding channel 211. The mounting plate 11 has first fixing members 12 at its four corners. The first fixing members 12 penetrate the mounting plate 11 and the top of the broadcasting base 21 longitudinally. The feeding channel 211 is connected to the discharge channel 28.

[0028] The first fixing member 12 connects the connecting square tube 13 and the mounting plate 11 to install the storage hopper 1 on the top right side of the spreading base 21. During installation, ensure that the discharge end of the connecting square tube 13 is accurately aligned with and installed at the feed channel 211 on the top of the spreading base 21, and that the two are connected. Next, the first fixing member 12 is used to secure the mounting plate 11 and the spreading base 21. Specifically, the first fixing member 12 is a cylindrical head hexagon socket screw. Threaded holes are provided at the four corners of the top of the spreading base 21 and the mounting plate 11. These threaded holes should match the external threads of the first fixing member 12. During installation, the first fixing member 12 is inserted through the pre-drilled threaded hole in the mounting plate 11 until it completely passes through the mounting plate 11 and extends into the corresponding threaded hole on the top of the spreading base 21. Then, the first fixing member 12 is tightened using a hexagon wrench or similar tool to securely connect the mounting plate 11 and the spreading base 21.

[0029] The connection between the feeding channel 211 and the discharging channel 28 is the movement path of the polymer material from the storage hopper 1 to the spreading roller 22 and finally spread onto the surface of the core 4. Specifically, the polymer material first enters the connecting square tube 13 through the storage hopper 1, and then enters the feeding channel 211 of the spreading seat 21 through the discharge end of the connecting square tube 13. In the feeding channel 211, the polymer material is guided to the discharging channel 28, and is evenly spread onto the surface of the core 4 as the spreading roller 22 rotates and through the discharge port 281 of the discharging channel 28.

[0030] As one of the preferred embodiments of this utility model, such as Figure 3 As shown, the discharge channel 28 is provided with a spreading port 27 below the spreading roller 22. The discharge channel 28 is provided with an inwardly extending inclined surface 281 at the position of the spreading port 27. The height of the discharge channel 28 where the inclined surface 281 is located gradually decreases along the material movement direction and toward the spreading port 27.

[0031] The polymer material is discharged from the spreading port 27 of the discharge channel 28. Since the spreading port 27 extends inward to the inclined surface 281, the height of the discharge channel 28 at the inclined surface changes, that is, the height gradually decreases along the material movement direction and toward the spreading port 27, so that the height of the spreading port 27 is less than the height of the discharge channel 28. When the polymer material passes through the spreading port 27, it is subjected to a certain amount of compression and concentration, which makes the spread polymer material more dense and uniform, thus helping to form a continuous and uniform base spreading layer 41 on the surface of the core 4.

[0032] In the polymer targeted spreading device of this utility model, the feeding channel 211 is connected to the discharging channel 28. The discharging channel 28 is located between the spreading roller 22 and the spreading seat 21. The polymer enters the feeding channel 211 of the spreading seat 21 through the connecting square tube 13 of the storage hopper 1. A portion of the polymer directly enters the spreading groove 221 of the spreading roller 22. After the spreading groove 221 is filled, a portion of the polymer enters through the feeding channel 211 and fills the discharging channel 28, thus opening the spreading groove 221 in the feeding channel 211. Finally, the core 4 is filled with polymer. The polymer is spread out from the discharge channel 28 and the spreading groove 221 through the rotation of the spreading roller 22 on the spreading seat 21. The polymer in the discharge channel 28 is continuously and evenly spread on the surface of the core 4, thereby forming a basic spreading layer 41 on the surface of the core 4. The polymer in the spreading groove 221 is spread at intervals and at fixed points and in a fixed quantity on the surface of the polymer in the basic spreading layer 41, thereby forming a reinforcing layer 42, so that the polymer is spread quantitatively and in a fixed position on the core 4.

[0033] As one of the preferred embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 4As shown, the end of the drive shaft 23 away from the drive motor 26 is axially disposed inside the spreading roller 22. An installation channel 222 is axially provided inside the spreading roller 22. The shape and size of the installation channel 222 match the end of the drive shaft 23 away from the drive motor 26. Several second fixing members 29 are provided on the side of the spreading roller 22 away from the drive motor 26 in a rotationally symmetrical manner. One end of the second fixing member 29 axially passes through the spreading roller 22 and is fixedly placed inside the drive shaft 23. Second bearings 223 are respectively sleeved on both ends of the spreading roller 22, and the second bearings 223 are installed between the spreading seat 21 and the spreading roller 22.

[0034] The power output shaft of the drive motor 26 is directly connected to one end of the drive shaft 23. When the drive motor 26 starts, the power generated by the drive motor 26 is transmitted to the drive shaft 23 through the power output shaft. After receiving the rotational power from the drive motor 26, the drive shaft 23 starts to rotate. Since the drive shaft 23 is fixedly connected to the spreading roller 22, the spreading roller 22 will also rotate with the drive shaft 23. Several spreading grooves 221 are equidistantly arranged on the circumferential surface of the spreading roller 22. During the rotation, they will pass through the spreading opening 27 in sequence, thereby spreading the polymer material in the groove. Second bearings 223 are installed at both ends of the spreading roller 22. The inner ring of the second bearing 223 is in close contact with the spreading roller 22, and the outer ring is in close contact with the spreading seat 21, thereby firmly installing the spreading roller 22 on the inner side of the spreading seat 21. The second bearing 223 can reduce the friction between the spreading roller 22 and the spreading seat 21 when the spreading roller 22 rotates.

[0035] The second fixing member 29 is used to fix the end of the drive shaft 23 away from the drive motor 26 inside the spreading roller 22. The second fixing member 29 is a cylindrical head hexagon socket screw. When fixing the end of the drive shaft 23 away from the drive motor 26 inside the spreading roller 22, the end of the drive shaft 23 away from the drive motor 26 is axially inserted into the mounting channel 222 of the spreading roller 22 until the end face of the end of the drive shaft 23 away from the drive motor 26 contacts the inner side wall of the spreading roller 22 on the side away from the drive motor 26. After the drive shaft 23 is correctly inserted into the spreading roller 22... Using a cylindrical head hexagon socket screw as the second fixing member 29, one end of which is axially passed through the side wall of the spreading roller 22 and screwed into the pre-set threaded hole inside the drive shaft 23. Since the second fixing member 29 is rotationally symmetrically distributed, multiple screws are needed to ensure a firm connection between the drive shaft 23 and the spreading roller 22. Then, the second fixing member 29 is tightened with tools such as an Allen wrench to ensure the reliability and stability of the connection, thereby completing the installation and fixing of the end of the drive shaft 23 away from the drive motor 26 inside the spreading roller 22.

[0036] As one of the preferred embodiments of this utility model, such as Figure 1 and Figure 2As shown, the fixed sleeve 24 has a fixed ring 241 fixedly connected to the circumferential surface of one end near the drive motor 26. The fixed ring 241 has a fixed hole 242 axially penetrating through its side. The fixed holes 242 are distributed rotationally symmetrically on the side of the fixed ring 241. A first bearing 25 is installed inside the fixed sleeve 24 at the corresponding position of the fixed ring 241. The first bearing 25 supports and allows the drive shaft 23 to rotate inside the fixed sleeve 24.

[0037] The function of the fixed sleeve 24 is to fix the spreading roller 22 to the frame via the drive shaft 23, so as to achieve stable rotation of the spreading roller 22. The fixed sleeve 24 wraps around the drive shaft 23 and is supported by the first bearing 25. The first bearing 25 can reduce friction and allow the drive shaft 23 to rotate smoothly within the fixed sleeve 24. A fixing ring 241 is provided at one end of the fixed sleeve 24 near the drive motor 26. A fixing hole 242 is axially provided on the side of the fixing ring 241. The fixing holes 242 are rotationally symmetrically distributed on the side of the fixing ring 241. These fixing holes 242 are used to fix the fixed sleeve 24 (and the spreading roller 22 connected by the drive shaft 23) to the frame with bolts or other fasteners. When the fixed sleeve 24 is fixed to the frame via the fixing ring 241 and the fixing holes 242, the drive shaft 23 and the spreading roller 22 are firmly supported in the predetermined position, thereby ensuring that the spreading roller 22 can rotate stably with the drive shaft 23.

[0038] As one of the preferred embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the fixing frame 3 includes a horizontal plate 31, a vertical plate 32, and a reinforcing plate 33. The horizontal plate 31 and the vertical plate 32 are perpendicular to each other and their ends are connected to each other. The reinforcing plate 33 is disposed on the intersecting vertical plane of the horizontal plate 31 and the vertical plate 32 and is connected to the horizontal plate 31 and the vertical plate 32 respectively. The horizontal plate 31 is connected to the side of the spreading seat 21. The surface of the vertical plate 32 has mounting holes 34 symmetrically arranged on the upper and lower sides of the reinforcing plate 33.

[0039] The function of the fixing frame 3 is to stably fix the spreading seat 21 on the machine frame to ensure that the spreading roller 22 can rotate in coordination with the spreading seat 21 to achieve the spreading of polymer materials. The fixing frame 3 is composed of a horizontal plate 31, a vertical plate 32 and a reinforcing plate 33. The horizontal plate 31 and the vertical plate 32 are perpendicular to each other and connected at one end to form a stable frame. The reinforcing plate 33 is set on the intersecting vertical surface of the horizontal plate 31 and the vertical plate 32 and is connected to the horizontal plate 31 and the vertical plate 32 respectively, which further enhances the overall rigidity and stability of the fixed frame 3. On the surface of the vertical plate 32, the upper and lower sides of the reinforcing plate 33 are symmetrically provided with mounting holes 34. These mounting holes 34 are used to fix the fixed frame 3 (and the spreading seat 21 connected thereto) to the frame by bolts or other fasteners. The horizontal plate 31 is connected to the side of the spreading seat 21, so that the spreading seat 21 can be firmly fixed on the fixed frame 3, thereby ensuring the relative position stability between the spreading seat 21 and the spreading roller 22, thus realizing the cooperative rotation between the spreading seat 21 and the spreading roller 22.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
