Description

Technical Field

[0001] The utility model relates to the technical field of medical nursing pads, in particular to a pulverizer for raw material pulp used in the production of medical nursing pads. Background Art

[0002] Nursing pads are not diapers. They are disposable sanitary products made of PE film, non-woven fabrics, fluff pulp, polymers and other materials. They are mainly used in hospital surgeries, gynecological examinations, maternal care, childcare, paralyzed patients with incontinence, and women's menstrual period. Nursing pads are called different names according to their uses. Nursing pads for infants and young children are called urine-isolating pads, nursing pads for maternal care are called postpartum pads, and nursing pads for women's menstrual period are called menstrual mattresses. The cotton core of the nursing pad is made of wood pulp, which needs to be crushed before it can be made into the cotton core. The existing technology has the following problems:

[0003] Chinese patent document CN218690158U discloses a pulverizer for medical nursing pad production raw material pulp, which relates to the technical field of medical nursing pad raw material pulp production. The pulverizer comprises a body, a servo motor is installed on the outside of the body, and a rotating rod is connected to the output end of the servo motor, a drum is installed on the outside of the rotating rod, and a connecting rod is provided inside the drum, a crushing knife is installed on the outside of the connecting rod, and an electric push rod is installed on one end of the connecting rod, and a drive motor is provided on the other end of the electric push rod, and a cover is installed on the outside of the electric push rod. In the utility model, a body, a rotating rod, a servo motor, a drum and a crushing knife are provided. By controlling the servo motor, the drum can be easily driven to rotate, so that the qualified raw materials crushed in the drum flow through the sieve holes of the drum to the discharge port, thereby preventing unqualified raw materials from mixing with qualified raw materials, shortening the raw material crushing time, and improving the crushing efficiency.

[0004] In the above-mentioned document, the connecting rod together with the crushing knives on both sides need to be extended into the drum under the drive of the electric push rod. Therefore, the end of the drum close to the cover is in an open state. This results in that when the cover is rotated to open after the crushing is completed, wood pulp will inevitably fall out. At the same time, some wood pulp debris will remain in the drum, which is inconvenient to clean and affects the next crushing work. At the same time, due to the deep depth of the drum, the crushing knife only relies on the forward and backward movement of the electric push rod for crushing. When a lot of wood pulp is stuffed into the drum, it cannot be crushed quickly and the crushing efficiency is still low. Utility Model Content

The rotation direction of the output shaft of the dual-axis motor 13 is consistent with that of the crushing motor 112. Under the meshing relationship between gear 131 and outer gear ring 121, the rotation direction of the screening drum 12 will be opposite to that of the crushing blades 114, so that the wood pulp in the inner cavity of the screening drum 12 can be crushed more thoroughly and evenly.

[0028] like Figure 5 As shown, a feed ring 17 is movably installed on the top of the crusher housing 1, and a feed funnel 172 is fixedly installed on the top of the feed ring 17. The inner cavity of the feed ring 17 is connected to the inner cavity of the fixed ring 11 from top to bottom. The outer wall of the feed ring 17 is fixedly installed with an outer gear ring 2 171. The upper output shaft of the dual-axis motor 13 passes through the top of the crusher housing 1 and is fixedly installed with a gear 2 132. The gear 2 132 is meshed with the outer gear ring 2 171.

Four groups of two scrambling rods 173 distributed vertically are fixedly installed on the inner ring annular array of the feed ring 17, and the scrambling rod 173 is located between two adjacent cross-shaped fixed rods 1122.

[0029] When in use, wood pulp is put into the feed ring 17 from the feed funnel 172, and the dual-axis motor 13 is started at the same time to drive the gear 2 132 to rotate. The engagement of the gear 2 132 and the outer gear ring 2 171 can drive the entire feed ring 17 to rotate on the top of the crusher case 1, and the staggered movement between the disrupting rod 173 on the inner ring of the feed ring 17 and the cross-shaped fixed rod 1122 on the outer wall of the top vertical rod 1121 of the crushing motor 112 is utilized to disrupt and separate the large pieces of wood pulp, and continue to fall downwards, saving the time for the next crushing step.

[0030] The following is a detailed description of the working principle of the pulp crusher used to produce the raw material of medical nursing pads.

[0031] like Figure 1-5As shown, when in use, wood pulp is put into the feed ring 17 from the feed hopper 172, and the dual-axis motor 13 is started to drive the gear 2 132 to rotate, and the engagement of the gear 2 132 with the outer gear ring 2 171 can drive the entire feed ring 17 to rotate on the top of the crusher box 1, and the interlaced movement between the disrupting rod 173 on the inner ring of the feed ring 17 and the cross-shaped fixing rod 1122 on the outer wall of the top vertical rod 1121 of the crushing motor 112 is used to disrupt and separate the large pieces of wood pulp, and continue to fall downward, and at the same time, the fixing rod 1122 is started. The crushing motor 112 at the left end of the rod 111 can quickly crush the small pieces of wood pulp that have fallen down by using the high-speed rotating rod 113 and the several crushing blades 114 on the outer wall. The output shaft rotation direction of the dual-axis motor 13 is consistent with that of the crushing motor 112. Under the meshing relationship between the gear 131 and the outer gear ring 121, the rotation direction of the screening drum 12 will be opposite to that of the crushing blades 114, so that the wood pulp in the inner cavity of the screening drum 12 can be crushed more thoroughly and evenly, and the wood pulp raw materials of qualified size can be crushed from the screening hole 12. 2 and the second screening hole 126 opened by the flip bottom plate 125 are discharged and discharged through the discharge funnel 16. The staff only needs to place the container for receiving qualified wood pulp raw materials at the bottom of the discharge funnel 16. When the collection is completed and the screening cylinder 12 needs to be cleaned, it is only necessary to take away the container for receiving qualified wood pulp fragments and place a new container at the bottom of the discharge funnel 16. Then, the servo motor 123 is controlled to start and drive the flip bottom plate 125 to rotate vertically from the bottom of the screening cylinder 12, and some remaining debris can directly fall into the discharge funnel 16. At the same time, when cleaning, the screening drum 12 still starts the dual-axis motor 13 to drive it to rotate at the bottom of the fixed ring 11, and starts the air pump 14 to input high-pressure gas into the inner cavity of the air box 15 through the air pipe 141, and sprays it to the rotating screening drum 12 through the air nozzle 151. Every time the screening hole 122 passes the air nozzle 151, the debris remaining in the screening hole 122 will be blown out and fall into the discharge funnel 16, thereby avoiding clogging of the screening hole 122 and affecting the next screening work, and conveniently and quickly cleaning the inner cavity of the screening drum 12.

[0032] While the present invention has been generally described above, it is readily apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are intended to be within the scope of protection of the present invention.
