Description

Technical Field

[0001] The utility model relates to the technical field of diaper core production devices, in particular to a polymer blanking device for core production. Background Art

[0002] The general process of producing diaper cores is as follows: first, the wood pulp paper is crushed by a crusher, and then blown into the mixing chamber of the core forming device through high-speed airflow. At the same time, the polymer material is also added to the mixing chamber through the lower device, and mixed evenly under the action of the airflow or stirring device in the mixing chamber. Then, the core forming mechanism of the core forming device performs die wheel molding and non-woven fabric coating on the mixed material of the polymer material and wood pulp to obtain the core of the diaper.

[0003] The feeding method of the polymer material into the mixing chamber through an inclined pipe, and its dispersion state when entering the mixing chamber, have a more obvious impact on the uniform mixing of the polymer material and the wood pulp. In the existing wood pulp and polymer material mixing equipment, most of the equipment adopts an inclined pipe, and uses gravity to directly introduce the polymer material from the discharge bin into the mixing chamber of the mixing equipment. However, this feeding method often causes the polymer material to fall more concentratedly, and then unevenly distributed in the mixing chamber, thereby affecting its mixing effect with the wood pulp. Therefore, the dispersion state of the polymer material when entering the mixing chamber becomes a more critical factor affecting the mixing uniformity and the quality of the final product. In the existing technology, the mixing equipment described in some patents (such as CN201410105742.0, CN202321997698.X, etc.) also has the above-mentioned problem in its polymer material feeding method, resulting in uneven mixing of wood pulp and polymer materials.

[0004] In summary, in the production process of diaper cores, uniform mixing of polymer materials and wood pulp is a key step to ensure the quality of the final product. However, existing mixing equipment generally has problems in the feeding method, that is, the polymer material directly enters the mixing chamber through a single inclined pipe, resulting in its landing point in the mixing chamber being concentrated and unevenly distributed, which in turn affects the mixing effect with the wood pulp.

DETAILED DESCRIPTION

[0023] The following describes the implementation of the present invention in conjunction with the accompanying drawings and relevant embodiments. The implementation of the present invention is not limited to the following embodiments, and the present invention involves relevant necessary components in this technical field, which should be regarded as common knowledge in this technical field and can be known and mastered by technical personnel in this technical field.

[0024] like Figures 1 to 6As shown, the utility model provides a technical solution: a polymer feeding device for core production, comprising a feeding hopper 1, a feeding hopper 2, a feeding pipe 3, and a feeding pipe 4, the discharge end of the feeding hopper 2 2 is connected to the feed end of the feeding pipe 4, the feeding hopper 1 is arranged above the feeding hopper 2, the discharge end of the feeding hopper 1 is connected to the feed end of the feeding hopper 2, the feeding pipe 3 comprises a conveying pipe 31, a blowing pipe 32 and a connecting pipe 33, the blowing pipe 32 and the connecting pipe 33 are connected to the conveying pipe 31, the discharge end of the feeding pipe 3 is connected to the feed end of the feeding pipe 4, and a guide block 43 is fixedly installed in the discharge end of the feeding pipe 4.

[0025] The polymer feeding device of the present invention is mainly used in the core production process to transport the polymer material from the silo to the mixing chamber of the mixing device where it is mixed with wood pulp. In the polymer feeding device of the present invention, the polymer material enters the feeding hopper 1, is collected by the feeding hopper 2, and then a high-speed airflow is introduced through the blowing pipe 32 of the feeding pipe 3 to blow the material into the feeding pipe 2 41 and into the discharge flat pipe 42. In the discharge flat pipe 42, the material collides with the guide block 43, so that it is ejected in a dispersed splashing state, thereby entering the wood pulp mixing chamber. When the polymer material is in the mixing chamber of the mixing device, it can be evenly dispersed, thereby improving the mixing efficiency and product quality. The high-speed airflow introduced by the blowing pipe 32 sprays the polymer material into the mixing chamber in a dispersed splashing state, so that the polymer material can be more evenly dispersed in the wood pulp, thereby improving the mixing efficiency and mixing uniformity. The fixing plate 12 is used to fix the feed port of the V-shaped square tube 11 and the discharge port of the polymer material, and the mounting plate 5 is used to fix the conveying pipe 41 to the outer wall of the mixing chamber of the mixing device, so that the overall polymer feeding device is stably fixed.

[0026] As one of the preferred embodiments of the present invention, Figures 1 to 3 As shown, the lower hopper 1 includes a V-shaped square tube 11 and a fixing plate 12 connected to two feed ports at the top position of the V-shaped square tube 11 respectively, and a number of evenly distributed fixing holes 13 are arranged at the edge position of the fixing plate 12, and a discharge port is provided at the bottom of the V-shaped square tube 11; the lower hopper 2 includes an upper connecting part 21 and a lower connecting part 22, the bottom end of the upper connecting part 21 is connected to the top end of the lower connecting part 22, the upper connecting part 21 is connected to the discharge port at the bottom of the V-shaped square tube 11, and the bottom end of the lower connecting part 22 is connected to the connecting pipe 33, the upper connecting part 21 is an inverted prism with the interior penetrating up and down, and the lower connecting part 22 is a hollow tube.

[0027] In the structure of the lower hopper 1, the polymer material enters from the two feed ports of the V-shaped square tube 11 and slides down and gathers at the bottom discharge port of the V-shaped square tube 11. The two feed ports of the V-shaped square tube 11 can improve the discharge efficiency of the polymer material, thereby providing a stable supply of raw materials for the subsequent mixing process. The fixing plate 12 is connected to the top position of the V-shaped square tube 11, and fixing holes 13 are set through its four corners. The operator can use bolts or other fasteners to install the lower hopper 1 on the discharge port of the polymer material silo through the fixing holes 13.

[0028] In the structure of the lower hopper 2, the lower hopper 2 is a connecting piece used for transition between the lower hopper 1 and the lower feeding pipe 3. The upper connecting part 21 is connected to the discharge port at the bottom of the V-shaped square tube 11, and is in the shape of an inverted prism with the upper and lower parts penetrating internally. It can further collect the polymer material flowing out of the lower hopper 1 and guide it to flow smoothly to the lower connecting part 22. The lower connecting part 22 is in the shape of a hollow tube, and its bottom end is connected to the connecting pipe 33, so that the polymer material can smoothly transition from the upper connecting part 21 to the lower connecting part 22, and finally enter the connecting pipe 33, preparing for the subsequent blowing and dispersion process.

[0029] As one of the preferred embodiments of the present invention, Figure 1 and Figure 4 As shown, the blowing pipe 32 and the connecting pipe 33 are inclined in the same direction on the conveying pipe 31, and the installation positions of the blowing pipe 32 and the connecting pipe 33 on the surface of the conveying pipe 31 are located on the same straight line along the axial direction; a block 34 that does not completely close the port is provided at the port position of the conveying pipe 31 away from one end of the connecting pipe 33, and the block 34 is installed at the port position of the conveying pipe 31 away from one end of the connecting pipe 33 to form an air inlet 35.

[0030] The discharge pipe 1 3 draws the polymer material out of the discharge hopper 2 2 through the coordinated action of the conveying pipe 1 31 , the blowing pipe 32 and the connecting pipe 33 inside it, and blows the polymer material into the conveying pipe 2 41 through the high-speed airflow introduced by the blowing pipe 32, and finally sprays it out in a dispersed splashing state, providing favorable conditions for the subsequent mixing process.

[0031] The inclined lower end of the blowing pipe 32 is inserted as a whole into the conveying channel inside the conveying pipe 31, and a narrow gap is formed between it and the inner wall of the conveying pipe 31 below it. When the high-speed blower is connected to the blowing pipe 32 through the air supply pipe, a high-speed airflow is introduced through the blowing pipe 32, and the connecting pipe 33 connects the lower hopper 22 and the conveying pipe 31, so that the polymer material can enter the conveying pipe 31 from the lower hopper 22. During the conveying process, in order to avoid the formation of low air pressure in the conveying pipe 31, thereby affecting the conveying effect of the polymer material, a block 34 that does not completely close the port is provided at the port position of the conveying pipe 31 away from one end of the connecting pipe 33. An air inlet 35 is formed between the block 34 and the inner wall of the conveying pipe 31, allowing air to enter the interior of the conveying pipe 31, thereby maintaining the air pressure in the conveying pipe 31 stable.

[0032] As one of the preferred embodiments of the present invention, Figure 1 、 Figure 5 、 Figure 6 As shown, the discharge pipe 4 includes a conveying pipe 41 and a discharge flat pipe 42. The discharge flat pipe 42 is provided with a round end and a flat end. The round end of the discharge flat pipe 42 is connected to the discharge end of the conveying pipe 41, and the feed end of the conveying pipe 41 is connected to the discharge end of the conveying pipe 1 31; the guide block 43 is arranged in the flat end of the discharge flat pipe 42, and a fixing part 44 is provided longitudinally through the flat end of the discharge flat pipe 42. The guide block 43 is fixedly installed in the flat end of the discharge flat pipe 42 through the fixing part 44.

[0033] The discharge flat tube 42 is the terminal part of the discharge pipe 4, and its round end is connected to the discharge end of the conveying pipe 41 to ensure that the polymer material can smoothly enter the discharge flat tube 42 from the conveying pipe 41. The flat end is the outlet of the polymer material. The flat shape of the flat end helps the polymer material to form a dispersed splashing state during injection. The guide block 43 is arranged in the flat end of the discharge flat tube 42. Its function is to change the flow direction of the polymer material and make it collide with the inner wall of the discharge flat tube 42 and the guide block 43 itself, which helps the polymer material to form a more dispersed splashing state during injection, thereby ensuring that the polymer material can be evenly dispersed when entering the mixing chamber of the mixing device for mixing wood pulp. The fixing part 44 longitudinally passes through the flat end of the discharge flat tube 42 and is used to fix the guide block 43 in the discharge flat tube 42.

[0034] It should be noted that the shape of the guide block 43 is set to be triangular, and its installation method is: the bottom surface of the guide block 43 is placed on the flat end of the discharge flat tube 42, and the top angle opposite to the bottom surface of the guide block 43 faces the round end of the discharge flat tube 42. The fixing part 44 is made of bolts and nuts, and the bolts are passed through the flat end of the discharge flat tube 42 and the reserved holes on the guide block 43, and then tightened with nuts to achieve fixation.

[0035] As one of the preferred embodiments of the present invention, Figure 1 As shown, the outer portion of the second delivery pipe 41 is movably connected to a mounting plate 5, and a plurality of evenly distributed mounting holes 51 are provided through the edge of the mounting plate 5, and a sliding channel 52 matching the diameter of the second delivery pipe 41 is provided at the center of the mounting plate 5.

[0036] The mounting plate 5 is movably sleeved on the conveying pipe 2 41 so that the mounting plate 5 can be moved or adjusted along the axial direction of the conveying pipe 2 41. The edge of the mounting plate 5 is penetrated by evenly distributed mounting holes 51 along the thickness direction. The mounting holes 51 are used to fix the mounting plate 5 and the conveying pipe 2 41 connected thereto and the entire unloading device on the outer wall of the mixing chamber of the mixing device, thereby facilitating the discharge flat tube 42 to extend into the mixing chamber of the mixing device. Specifically, the conveying pipe 2 41 is fixed to the mixing chamber of the mixing device by connecting the mounting hole 51 of the mounting plate 5 to the fixing parts (such as bolts, nuts, etc.) on the outer wall of the mixing chamber of the mixing device.

[0037] The polymer feeding device of the present invention is mainly used in the core production process to transport the polymer material from the silo to the mixing chamber of the mixing device where it is mixed with wood pulp. Its working principle is as follows: the polymer material first enters through the two feed ports at the top of the V-shaped square tube 11 of the lower hopper 1, and the polymer material slides down under the action of gravity and gathers at the bottom discharge port of the V-shaped square tube 11. The polymer material gathered at the bottom of the V-shaped square tube 11 enters the lower hopper 2 through the discharge port, and enters the connecting pipe 33 through the lower connecting part 22 of the lower hopper 2, and then continues to flow to the conveying pipe 1 31. The blowing pipe 32 is connected to the conveying pipe 31. The passage is used to connect a high-speed fan. The high-speed airflow generated by the high-speed fan is introduced into the conveying pipe 31 through the blowing pipe 32, forming a powerful blowing force. Under the action of the blowing force, the polymer material in the conveying pipe 31 is blown into the conveying pipe 41 and continues to flow to the discharge flat pipe 42. When passing through the discharge flat pipe 42, the polymer material collides violently with the guide block 43, so that the polymer material is ejected in a relatively dispersed splashing state at the discharge end of the discharge flat pipe 42, thereby dispersing the splashed polymer material into the mixing chamber of the mixing device, and can be more evenly dispersed in the wood pulp, thereby improving the mixing efficiency and mixing uniformity.

[0038] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
