Description

Technical Field

[0001] This utility model relates to a pulp pulverizer for nursing pad raw materials, specifically a pulp pulverizer for nursing pad raw materials, and belongs to the technical field of pulp pulverizing devices. Background Technology

[0002] The nursing pad raw material pulp pulverizer is a device specifically designed to pulverize the pulp raw materials required for nursing pad production. It uses high-speed rotating blades or grinding components to break down and grind lumpy and flaky pulp raw materials into uniform fibrous pulp that meets production requirements. This provides fine, well-dispersed raw materials for subsequent processing of the absorbent layer, surface layer, and other structures of the nursing pad, ensuring that the nursing pad possesses excellent absorbency, softness, and other properties. It is one of the key pieces of equipment for achieving refined raw material processing in the nursing pad production process.

[0003] The prior art patent application number (201820956147.1) entitled "A Pulp Crusher" includes a machine body comprising an inner body and an outer body connected to each other, which are detachably connected. The inner body is equipped with a stirring device, and the outer body is equipped with a drive device for driving the stirring device. The stirring device includes a rotating shaft and propeller blades connected to the rotating shaft. The inner body has spiral strips forming guide grooves, and the spiral strips have storage grooves. Magnets are also installed inside the spiral strips. This invention effectively removes iron impurities from the pulp by utilizing the rotation of the pulp and the use of magnets, thus effectively preventing damage to the machine in the next process caused by iron impurities.

[0004] Existing pulverizing mechanisms rely solely on a motor to drive a pulverizing shaft, which rotates in one direction. The blades on the shaft cut and pulverize the pulp raw material, resulting in a fixed trajectory within the pulverizing chamber. This makes it difficult to achieve uniform pulverization from all angles and directions. Furthermore, localized stress concentration can lead to over-pulverization of some materials while others remain in larger fiber form due to insufficient contact with the blades. Ultimately, the pulverizing effect is mediocre. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0005] The purpose of this invention is to provide a pulp pulverizer for nursing pads in order to solve the above-mentioned problems. This invention addresses the issues in the prior art, which not only makes it difficult to achieve uniform crushing from all directions and multiple angles, but also may cause some raw materials to be over-crushed due to localized stress concentration, while others may retain a larger fiber shape because they do not fully contact the blades.

[0006] This utility model is achieved through the following technical solution: a pulp pulverizer for nursing pad raw materials.

[0007] The device includes a crushing chamber, with a feed inlet fixedly connected to the top and a discharge valve fixedly connected to the bottom. A motor is fixedly connected to the top of the crushing chamber, and the bottom end of the motor's power output shaft passes through the crushing chamber and extends into its inner cavity. A mounting chamber is also fixedly connected to the bottom end of the motor's power output shaft, allowing the motor to directly drive the mounting chamber to rotate. This simplifies the power transmission structure and improves transmission efficiency. The feed inlet and discharge valve enable continuous feeding and discharging of raw materials, facilitating automated production. Simultaneously, the discharge valve controls the discharge speed, preventing the discharge of insufficiently crushed raw materials.

[0008] Preferably, the installation chamber has two transmission chambers inside, and the inner cavity of the installation chamber is rotatably connected to two gear driven rods. The design of the two transmission chambers and gear driven rods provides installation space and transmission foundation for dual-shaft crushing. Compared with the single-shaft structure, it can increase the contact opportunity between raw materials and crushing components and improve crushing efficiency. The rotatable connection of the gear driven rods ensures the flexibility and stability of transmission.

[0009] Preferably, one end of the gear driven rod passes through the mounting chamber and extends into the inner cavity of the transmission chamber, and a first drive gear is fixedly connected to the outer side of the gear driven rod. The setting of the first drive gear realizes the meshing transmission of the gear driven rod with other gears, ensuring that the power can be stably transmitted to the subsequent crushing components. The gear transmission method has the characteristics of precise transmission ratio and high efficiency, ensuring the stability of the crushing process.

[0010] Preferably, a driven gear is rotatably connected to the bottom of the inner cavity of the transmission chamber. The driven gear meshes with the first driving gear. The bottom end of the driven gear passes through the mounting chamber and extends to the bottom of the mounting chamber. The meshing of the driven gear with the first driving gear realizes the conversion and transmission of power direction, so that the rotational power of the mounting chamber can drive the driven gear to rotate. The driven gear extends to the bottom of the mounting chamber, providing structural support for connecting the crushing component and ensuring the effective execution of the crushing action.

[0011] Preferably, a crushing roller is fixedly connected to the bottom end of the driven gear, and a crushing plate is fixedly connected to the outer side of the crushing roller. The crushing plates are evenly distributed. When the crushing roller rotates with the driven gear, the evenly distributed crushing plates on the outer side can strike and cut the raw material at multiple angles and high frequencies, thereby improving the uniformity of crushing. The design of multiple crushing plates increases the contact area with the raw material, speeds up the crushing speed, and avoids local accumulation of raw material.

[0012] Preferably, a mounting frame is fixedly connected to the inner cavity of the crushing chamber, and a fixing rod is fixedly connected to the top of the mounting frame. The top end of the fixing rod passes through the mounting chamber and extends into the inner cavity of the mounting chamber. The mounting frame and the fixing rod form a stable fixed structure, providing fixed support for the second drive gear and ensuring that it remains stationary when the mounting chamber rotates, thereby realizing relative movement and meshing transmission with the gear driven rod and ensuring the power source for dual-shaft crushing.

[0013] Preferably, a second drive gear is fixedly connected to the top of the fixed rod. The second drive gear meshes with the driven gear rod. The meshing of the second drive gear with the driven gear rod utilizes the rotation of the mounting chamber to drive the driven gear rod to rotate, so that the crushing roller has both revolution and rotation motion states at the same time, which greatly improves the crushing force and uniformity of the raw materials and solves the problem of poor crushing effect of single-axis unidirectional rotation.

[0014] Preferably, the inner wall of the crushing chamber is fixedly connected with crushing teeth, which are evenly distributed. Connecting rods are fixedly connected to both sides of the installation chamber, and a cleaning scraper is fixedly connected to one end of each connecting rod. The cleaning scraper is in contact with the crushing chamber, and a through groove is formed on one side of the cleaning scraper, arranged sequentially from top to bottom. The through groove is located outside the crushing teeth. The crushing teeth on the inner wall of the crushing chamber cooperate with the rotating crushing plate to form a shearing action, further refining the raw materials. The cleaning scraper can promptly remove raw materials adhering to the inner wall of the crushing chamber, preventing accumulation and agglomeration that affects the crushing effect. The through groove design does not affect the normal operation of the crushing teeth, but ensures the smooth passage of the scraper, guaranteeing the cleaning effect without interfering with the crushing process.

[0015] This utility model provides a pulp pulverizer for nursing pad raw materials, which has the following beneficial effects: 1. This nursing pad raw material pulp pulverizer, through a multi-shaft pulverizing mechanism, allows the raw material to be cut and impacted in multiple directions and angles, greatly improving the uniformity of pulverization and avoiding the phenomenon of insufficient or excessive pulverization in some areas that occurs during single-shaft pulverization. At the same time, it increases the contact frequency between the raw material and the pulverizing components, improves pulverization efficiency, and provides higher quality pulp raw materials for subsequent nursing pad production.

[0016] 2. This nursing pad raw material pulp pulverizer, through its internal wall cleaning mechanism, can promptly remove raw material residues adhering to the inner wall of the pulverizing chamber, preventing raw material accumulation and clumping that affects the pulverizing effect, avoiding resource waste, reducing wear and tear on the equipment caused by raw material residue, extending the equipment's service life, and ensuring the continuity and stability of the pulverizing process.

Detailed Implementation

[0018] This utility model embodiment provides a pulp pulverizer for nursing pad raw materials.

[0019] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The device includes a crushing chamber 1, with a feed inlet 101 fixedly connected to the top of the crushing chamber 1, a discharge valve 102 fixedly connected to the bottom of the crushing chamber 1, a motor 2 fixedly connected to the top of the crushing chamber 1, the bottom end of the power output shaft of the motor 2 passing through the crushing chamber 1 and extending into the inner cavity of the crushing chamber 1, and an installation chamber 201 fixedly connected to the bottom end of the power output shaft of the motor 2.

[0020] Please refer to it again. Figure 1 , Figure 2 and Figure 3The installation chamber 201 has two transmission chambers 202 inside. Two gear driven rods 3 are rotatably connected to the inner cavity of the installation chamber 201. One end of each gear driven rod 3 passes through the installation chamber 201 and extends into the inner cavity of the transmission chamber 202. A first drive gear 301 is fixedly connected to the outer side of each gear driven rod 3. A driven gear 4 is rotatably connected to the bottom of the inner cavity of the transmission chamber 202. The driven gear 4 meshes with the first drive gear 301, and the bottom end of the driven gear 4 passes through the installation chamber 201 and extends into the inner cavity of the transmission chamber 202. At the bottom of the crushing chamber 1, a crushing roller 401 is fixedly connected to the bottom end of the driven gear 4. A crushing plate 402 is fixedly connected to the outer side of the crushing roller 401, and the crushing plates 402 are evenly distributed. A mounting frame 5 is fixedly connected to the inner cavity of the crushing chamber 1. A fixing rod 501 is fixedly connected to the top of the mounting frame 5. The top end of the fixing rod 501 passes through the mounting chamber 201 and extends into the inner cavity of the mounting chamber 201. A second drive gear 502 is fixedly connected to the top end of the fixing rod 501. The second drive gear 502 meshes with the gear driven rod 3.

[0021] The multi-axis crushing mechanism uses motor 2 as its power source. Motor 2 drives the mounting chamber 201 to rotate, and simultaneously, the second drive gear 502, fixed by the fixing rod 501, meshes with the driven gear 3. When the mounting chamber 201 rotates with the output shaft of motor 2, the driven gear 3 rotates under the action of the second drive gear 502, which in turn drives the driven gear 4 to rotate synchronously through the first drive gear 301. The crushing roller 401 connected to the bottom of the driven gear 4 therefore has two motion states simultaneously: it revolves with the mounting chamber 201 while also rotating around its own axis. This composite motion enables the crushing plates 402, which are evenly distributed on the outer side of the crushing roller 401, to strike and cut the pulp raw material entering the crushing chamber 1 from multiple angles and directions, while simultaneously forming a shearing engagement with the crushing teeth 6 fixed on the inner wall of the crushing chamber 1, ultimately achieving efficient and uniform crushing of the raw material.

[0022] Example 2, please refer to again. Figure 1 , Figure 2 and Figure 4 The inner wall of the crushing chamber 1 is fixedly connected with crushing teeth 6, and the crushing teeth 6 are evenly distributed. Both sides of the installation chamber 201 are fixedly connected with connecting rods 7. One end of the connecting rod 7 is fixedly connected with a cleaning scraper 701. The cleaning scraper 701 is in contact with the crushing chamber 1. A through groove 702 is opened on one side of the cleaning scraper 701, and the through grooves 702 are arranged from top to bottom. The through grooves 702 are located on the outside of the crushing teeth 6.

[0023] The inner wall cleaning mechanism is linked to the installation chamber 201. The cleaning scrapers 701, fixed on both sides of the installation chamber 201 by connecting rods 7, rotate synchronously with the installation chamber 201. The cleaning scrapers 701 fit tightly against the inner wall of the crushing chamber 1, and can scrape off the raw material residue adhering to the chamber wall during rotation, preventing accumulation and agglomeration. Since a through groove 702 corresponding to the position of the crushing teeth 6 is opened on one side of the cleaning scraper 701, the through groove 702 will pass through the outside of the crushing teeth 6 when the scraper rotates. This avoids interference between the scraper and the crushing teeth 6, and does not affect the normal crushing function of the crushing teeth 6. Thus, the inner wall of the crushing chamber 1 is kept clean without interrupting the crushing operation, ensuring a stable and efficient crushing process.

[0024] Working Principle: The multi-axis crushing mechanism uses motor 2 as its power source. Motor 2 drives the mounting chamber 201 to rotate, and simultaneously, the second drive gear 502, fixed by the fixing rod 501, meshes with the driven gear 3. When the mounting chamber 201 rotates with the output shaft of motor 2, the driven gear 3 rotates under the action of the second drive gear 502, which in turn drives the driven gear 4 to rotate synchronously through the first drive gear 301. The crushing roller 401 connected to the bottom of the driven gear 4 therefore has two motion states: it revolves with the mounting chamber 201 while also rotating around its own axis. This compound motion enables the crushing plates 402, which are evenly distributed on the outer side of the crushing roller 401, to strike and cut the pulp raw material entering the crushing chamber 1 from multiple angles and directions. At the same time, it forms a shearing engagement with the crushing teeth 6 fixed on the inner wall of the crushing chamber 1, ultimately achieving efficient and uniform crushing of the raw material. The inner wall cleaning mechanism is linked with the mounting chamber 201, and the cleaning scrapers 701, fixed on both sides of the mounting chamber 201 by the connecting rod 7, rotate synchronously with the mounting chamber 201. The cleaning scraper 701 fits tightly against the inner wall of the crushing chamber 1, scraping away raw material residue adhering to the chamber wall during rotation to prevent accumulation and clumping. Since a through groove 702 corresponding to the position of the crushing teeth 6 is provided on one side of the cleaning scraper 701, the through groove 702 passes through the outside of the crushing teeth 6 when the scraper rotates. This avoids interference between the scraper and the crushing teeth 6 without affecting their normal crushing function, thus maintaining the cleanliness of the inner wall of the crushing chamber 1 without interrupting the crushing operation, ensuring a stable and efficient crushing process.
