Description

Technical Field

[0001] This utility model relates to the field of sanitary napkin production technology, specifically an adjustable-size sanitary napkin forming mold. Background Technology

[0002] A sanitary napkin forming mold is a specialized mold used in the manufacture of sanitary napkins. Its main function is to precisely shape and size the various layers of materials (such as the top layer, absorbent core, and bottom layer) during the sanitary napkin production process. Through processes such as pressing with the mold, the materials are tightly bonded together to form the final shape of the sanitary napkin. An adjustable-size sanitary napkin forming mold is required in the sanitary napkin production process.

[0003] Currently, most existing sanitary napkin forming molds cannot be changed or adjusted according to the required sanitary napkin size. They also lack protective measures for workers during production. Since different sanitary napkins come in different sizes, the inability to adjust the mold according to production needs limits the device to producing only one size, narrowing its applicability. Furthermore, without adequate protection for those around the device, workers risk being caught in the rotating mold, resulting in injury. This compromises the mold's safety. Additionally, the difficulty in adjusting the mold to a suitable height and securing the device in a proper position is problematic. Different environments and the production of different sanitary napkins may require different heights; the inability to adjust the mold to the appropriate position in different environments renders it unusable, further reducing its flexibility and applicability. Finally, the cumbersome installation process may require specialized personnel or a lengthy time, further diminishing its practicality. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable-size sanitary napkin forming mold to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable-size sanitary napkin forming mold, comprising a support plate and a fixed cylinder, wherein a mold body is movably connected to the outer wall of the fixed cylinder, and an adjustment and protection mechanism is provided at one end of the mold body, the adjustment and protection mechanism comprising an mounting plate, and an mounting plate fixedly connected to one end of the mold body, wherein a first threaded hole is provided on one side of the mounting plate and inside the fixed cylinder, a fixing bolt is threadedly connected to the inner wall of the first threaded hole, a threaded rod is fixedly connected to the top of the support plate, a fixed plate is slidably connected to the outer wall of the threaded rod, a nut is threadedly connected to the outer wall of the threaded rod, the bottom of the nut is in contact with the top of the fixed plate, and a protective cover is fixedly connected to one side of the fixed plate.

[0006] As a preferred technical solution, the number of threaded rods is two, and the two threaded rods are symmetrically arranged with the vertical center line of the support plate as the axis of symmetry.

[0007] As a preferred technical solution, motor brackets are fixedly connected to both sides of the support plate, a motor is fixedly connected to the inner side of the motor brackets, and the output shaft of the motor is fixedly connected to the motor shaft through a coupling.

[0008] As a preferred technical solution, the outer wall of the motor shaft is connected through to one end of the support plate, and a fixing cylinder is fixedly connected to the outer wall of the motor shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, by adjusting the setting of the protective mechanism, can achieve the functions of adjusting and replacing molds of different sizes according to needs and protecting personnel. During use, the appropriate size mold is replaced onto the fixed cylinder through the cooperation of the first threaded hole and the fixing bolt. The protective cover is fixed above the mold body through the cooperation of the threaded rod and the nut. This can avoid the situation where the device can only produce sanitary napkins of one size because it is impossible to adjust and replace different molds according to production needs, thus ensuring the flexibility of the mold and preventing personnel from being injured by their hands being caught under the rotating mold due to the lack of protection for those around them. This ensures the safety of the mold during use.

[0013] 2. This utility model, through the setting of the lifting and mounting mechanism, can facilitate the lifting and lowering of the mold to a suitable height and the fixing of the device in a suitable position. During use, the device is fixed in a suitable position by cooperating with the second threaded hole and bolt on the mounting plate. By activating the electric push rod, the mold body is lifted and lowered to a suitable height. This avoids the situation where the mold cannot be used normally in different environments due to the inability to lift and lower the mold to a suitable position according to the actual situation, thus ensuring the flexibility and applicability of the mold. It also avoids the situation where the installation and fixing process of the device is cumbersome, which may require professional personnel or a long time to install and fix the device, thus ensuring the convenience of fixing the mold.

Both sides of the support plate 1 are fixedly connected to motor brackets 4. The inner side of the motor brackets 4 is fixedly connected to a motor 5. The output shaft of the motor 5 is fixedly connected to a motor shaft 6 through a coupling. The outer wall of the motor shaft 6 is connected through to one end of the support plate 1. The outer wall of the motor shaft 6 is fixedly connected to the fixed cylinder 7. The bottom of the support plate 1 is provided with a lifting and mounting mechanism 3.

[0023] When the mold body 8 is needed to produce sanitary napkins, the forming mold first needs to be fixed in a suitable position using the lifting and mounting mechanism 3. Then, different mold bodies 8 need to be adjusted and replaced according to the required sanitary napkin size using the adjustment and protection mechanism 2. The height of the mold body 8 needs to be adjusted according to different situations using the lifting and mounting mechanism 3. Before the mold body 8 starts working, protection needs to be provided to those around it to prevent injury. This is done using the adjustment and protection mechanism 2. Then, the sanitary napkin forming process can begin. The motor 5 is started, causing the motor shaft 6 to rotate. The motor shaft 6 then rotates the fixed cylinder 7, which in turn rotates the mold body 8. The rotation of the conveyor belt and the mold body 8 on the production line shapes the sanitary napkin raw materials on the conveyor belt, thus completing the process.

[0024] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, an adjustment and protection mechanism 2 is provided at one end of the mold body 8. The adjustment and protection mechanism 2 includes a mounting plate 201. The mounting plate 201 is fixedly connected to one end of the mold body 8. A first threaded hole 202 is opened on one side of the mounting plate 201 and inside the fixed cylinder 7. A fixing bolt 203 is threadedly connected to the inner wall of the first threaded hole 202. A threaded rod 204 is fixedly connected to the top of the support plate 1. A fixing plate 205 is slidably connected to the outer wall of the threaded rod 204. A nut 206 is threadedly connected to the outer wall of the threaded rod 204. The bottom of the nut 206 fits against the top of the fixing plate 205. A protective cover 207 is fixedly connected to one side of the fixing plate 205. There are two threaded rods 204, and the two threaded rods 204 are symmetrically arranged about the vertical center line of the support plate 1.

[0025] Specifically: When it is necessary to adjust and replace different mold bodies 8 according to the required sanitary napkin size, the appropriate mold body 8 is inserted into the outside of the fixed cylinder 7. Then, the mounting plate 201 on the mold body 8 is passed through the motor shaft 6, and the inner side of the mounting plate 201 is tightly attached to one side of the fixed cylinder 7. Then, the first threaded hole 202 on the mounting plate 201 is aligned with the first threaded hole 202 in the fixed cylinder 7. Then, the fixing bolt 203 is rotated and inserted into the first threaded hole 202, thereby fixing the mounting plate 201 on the fixed cylinder 7, thus completing the replacement and adjustment work. Before the mold body 8 is put into operation, it is necessary to protect the surrounding people to prevent injury to the surrounding staff. At this time, the fixing plate 205 is inserted into the threaded rod 204 through the through hole on the fixing plate 205. Then, the nut 206 is rotated in the threaded rod 204 to fix the fixing plate 205, thereby fixing the protective cover 207. The protective cover 207 is used to protect the surrounding people, thus completing the protection work.

[0026] like Figure 1 and Figure 6 As shown, a lifting and mounting mechanism 3 is provided at the bottom of the support plate 1. The lifting and mounting mechanism 3 includes an electric push rod 301. The bottom of the support plate 1 is fixedly connected to the electric push rod 301. There are two electric push rods 301, and the two electric push rods 301 are symmetrically arranged about the vertical center line of the support plate 1. The bottom end of the electric push rod 301 is fixedly connected to a connecting plate 302. The inner wall of the connecting plate 302 is provided with a second threaded hole 303.

[0027] Specifically: When the mold body 8 is needed to produce sanitary napkins, the molding mold must first be fixed in a suitable position. At this time, the bottom of the connecting plate 302 is attached to a suitable position on the production line. Then, the second threaded hole 303 on the connecting plate 302 is aligned with the second threaded hole 303 opened at a specific position. Then, the bolt is rotated and inserted into the second threaded hole 303 to fix the device in a suitable position, thus completing the installation work. When it is necessary to adjust the height of the mold body 8 according to different scenarios, the electric push rod 301 is activated to extend the electric push rod 301. The electric push rod 301 drives the support plate 1 to rise and fall, and the support plate 1 drives the mold body 8 to rise and fall to a suitable height, thus completing the lifting work.

[0028] The working principle of this utility model is as follows: When the mold body 8 is needed to produce sanitary napkins, the molding mold first needs to be fixed in a suitable position. At this time, the bottom of the connecting plate 302 is pressed tightly against the suitable position on the production line. Then, the second threaded hole 303 on the connecting plate 302 is aligned with the second threaded hole 303 opened at a specific position. Then, the bolt is rotated and inserted into the second threaded hole 303, thereby fixing the device in a suitable position and completing the installation work. Then, different mold bodies 8 need to be adjusted and replaced according to the required sanitary napkin size.
