Description

Technical Field

[0001] This utility model belongs to the technical field of bath towel embossing molds, and in particular relates to a bath towel embossing device with quick mold replacement. Background Technology

[0002] The main function of a bath towel is to clean the skin's surface of oil, sweat, and dead skin cells. Embossed bath towels refer to designs such as regular or irregular textures and raised patterns formed on the surface of the bath towel through mechanical pressing or textile processes. Dense or raised embossing can target and enhance cleaning, avoiding the "slippery" problem of ordinary flat bath towels. Currently, existing embossing devices typically use bolts to fasten the molds onto the processing table. When changing the molds, operators need to remove multiple bolts (usually 8 to 12) between the mold and the fixed mold base one by one. This is time-consuming and cumbersome, which seriously affects production efficiency. Frequent bolt removal can also lead to thread wear, increase the difficulty of calibration during mold installation, further reduce the mold change rate, and affect the company's production efficiency.

[0003] To address the aforementioned issues, this application proposes a quick-change mold embossing device for bath towels. Utility Model Content

[0004] The purpose of this invention is to provide a quick-change mold embossing device for bath towels, which solves the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a quick-change mold embossing device for bath towels, including a fixed mold base and a moving mold base, and two fixing plates fixedly mounted on the bottom surface of the fixed mold base. The fixed mold base is positioned above a processing table. The processing table has positioning slots that mate with the fixing plates. The fixing plates have two insertion holes. A plug block for insertion into the insertion holes is provided below the processing table. A buffer plate is positioned below the processing table. A spring is fixedly mounted at the bottom end of the buffer plate. The spring is used to prevent rigid collision between the fixed mold base and the processing table during installation.

[0006] Furthermore, a fixed shell is fixedly provided on the bottom surface of the processing table, and two movable seats are symmetrically provided inside the fixed shell. Smooth plates that penetrate the side wall of the fixed shell are fixedly provided on the mutually distant sides of the movable seats, and the smooth plates are respectively fixedly connected to the connecting seats. The connecting seats are fixedly connected to the insert block.

[0007] Furthermore, a rotating shaft is rotatably installed inside the fixed housing, and the outer wall of the rotating shaft is provided with two threaded sections. The two threaded sections have opposite thread directions and are respectively threadedly connected to the movable seats. A guide rod parallel to the rotating shaft is fixed inside the fixed housing, and the guide rod is slidably connected to the two movable seats.

[0008] Furthermore, a motor is installed on the outer wall of the fixed housing, and two meshing bevel gears are provided inside the fixed housing. One bevel gear is fixedly connected to the outer wall of the rotating shaft, and the other bevel gear is fixedly connected to the output shaft of the motor.

[0009] Furthermore, two symmetrically arranged L-shaped support frames are fixed on both sides of the bottom surface of the fixed shell, and the bottom end of the spring is fixedly connected to the L-shaped support frames.

[0010] Furthermore, the plug is wedge-shaped, and the socket matches the plug.

[0011] Furthermore, a smooth column is fixedly provided at the bottom end of the buffer plate, passing through the L-shaped support frame and slidably connected to the L-shaped support frame. The smooth column is set perpendicular to the horizontal plane, and a spring is wound around the smooth column. A limiting plate is provided below the L-shaped support frame and fixedly connected to the bottom end of the smooth column.

[0012] Furthermore, a rubber pad is fixed to the side of the buffer plate that contacts the fixing plate.

[0013] This utility model has the following beneficial effects: This utility model achieves horizontal limiting of the fixed mold base through the sliding fit between the fixed plate and the positioning through groove on the processing table, and then completes the locking through the insertion structure of the insert block and the insertion hole of the fixed plate. Only the extension and retraction of the insert block is needed to realize the quick installation or disassembly of the mold, which greatly shortens the mold change time of traditional bolt tightening or manual knocking. This invention provides elastic support during the installation of the fixed mold base through the cooperation of a buffer plate and a spring, creating a small gap between the bottom surface of the fixed mold base and the top surface of the processing table. This avoids equipment deformation or precision reduction caused by rigid collisions, effectively protects the structural integrity of the fixed mold base and the processing table, and extends the service life of the device.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] Please see Figure 1 - Figure 4 As shown, this utility model is a quick-change mold bath towel embossing device, including a fixed mold base 2 and a moving mold base 15, and two fixing plates 201 fixed on the bottom surface of the fixed mold base 2. The fixed mold base 2 is set above the processing table 1. The processing table 1 has a positioning through groove 101 that cooperates with the fixing plates 201. The fixing plates 201 have two insertion holes 2011. The processing table 1 has a plug 6 for insertion into the insertion holes 2011 below it. A buffer plate 13 is set below the processing table 1. A spring 14 is fixed at the bottom of the buffer plate 13. The spring 14 is used to prevent the fixed mold base 2 from rigidly colliding with the processing table 1 during installation. This embodiment provides a quick-change mold towel embossing device. During installation, the fixing plate 201 passes through the positioning slot 101. The positioning slot 101 cooperates with the fixing plate 201 to limit the position. Then, the insertion hole 2011 is located below the processing table 1. The mold is quickly installed by inserting the insertion block 6 into the insertion hole 2011. When installing the fixed mold base 2, the buffer plate 13 supports the fixing plate 201. The spring 14 will undergo elastic deformation and make the bottom surface of the fixed mold base 2 slightly higher than the top surface of the processing table 1. That is, when installing the fixed mold base 2, there is a gap between the fixed mold base 2 and the processing table 1, which can completely prevent the fixed mold base 2 from rigidly colliding with the processing table 1 during installation.

[0020] The bottom surface of the processing table 1 is fixedly provided with a fixed shell 3, and two movable seats 4 are symmetrically arranged inside the fixed shell 3. The sides of the movable seats 4 that are far apart from each other are fixedly provided with smooth plates 401 that penetrate the side wall of the fixed shell 3. The smooth plates 401 are respectively fixedly connected to the connecting seats 5. The connecting seats 5 are fixedly connected to the insert block 6. When the movable seats 4 move relative to each other, the smooth plates 401 drive the connecting seats 5 to move relative to each other, thereby realizing the insertion or separation of the insert block 6 and the insertion hole 2011, that is, realizing the quick locking or unlocking of the fixed mold base 2.

[0021] The fixed housing 3 has a rotating shaft 7 rotatably installed inside it, and the outer wall of the rotating shaft 7 has two threaded sections 701. The two threaded sections 701 have opposite thread directions and are respectively threaded to the movable seats 4. The fixed housing 3 has a guide rod 8 that is parallel to the rotating shaft 7 and is slidably connected to the two movable seats 4. The rotating shaft 7 rotates and the threaded sections 701 engage with the movable seats 4 to make the two movable seats 4 move synchronously in opposite directions. The guide rod 8 ensures that the movable seats 4 move only in the horizontal direction and avoids them from deviating.

[0022] The fixed housing 3 is equipped with a motor 10 on its outer wall and two meshing bevel gears 9 inside the fixed housing 3. One bevel gear 9 is fixedly connected to the outer wall of the rotating shaft 7 and the other bevel gear 9 is fixedly connected to the output shaft of the motor 10. The motor 10 drives the bevel gear 9 to rotate, thereby driving the rotating shaft 7 to rotate, so as to realize the synchronous reverse movement of the two moving seats 4.

[0023] Two symmetrically arranged L-shaped support frames 11 are fixed on both sides of the bottom surface of the fixed shell 3. The bottom end of the spring 14 is fixedly connected to the L-shaped support frame 11, and the L-shaped support frame 11 provides stable support for the spring 14.

[0024] The insert 6 is wedge-shaped, and the insertion hole 2011 matches the insert 6. The top surface of the insert 6 is provided with an inclined guide surface. When the fixed mold base 2 is installed, there is a gap between it and the processing table 1. The cross-section of the insertion hole 2011 is also wedge-shaped and has an inclined surface. The height of the insertion end of the wedge-shaped insert 6 is less than the height of the opening surface of the insertion hole 2011, so that the insert 6 can still be inserted into the insertion hole 2011 when there is a gap between the processing table 1 and the fixed mold base 2. Then, it continues to be inserted so that the insert 6 and the insertion hole 2011 are completely matched, thus locking the fixed mold base 2.

[0025] The buffer plate 13 has a smooth column 12 fixed at its bottom end, which passes through the L-shaped support frame 11 and is slidably connected to the L-shaped support frame 11. The smooth column 12 is set perpendicular to the horizontal plane, and the spring 14 is wrapped around the smooth column 12. A limiting plate 1201 fixed to the bottom end of the smooth column 12 is provided below the L-shaped support frame 11. The smooth column 12 guides the movement of the buffer plate 13 and prevents the buffer plate 13 from shifting.

[0026] Among them, a rubber pad 1301 is fixed on the side of the buffer plate 13 that contacts the fixed plate 201. The rubber pad 1301 further absorbs the collision energy and protects the surface of the fixed plate 201.

[0027] It is understood that this utility model can quickly unlock and lock the fixed mold base 2, enabling the quick replacement of the fixed mold base 2. Secondly, it provides a buffer for the fixed mold base 2 during installation to prevent the fixed mold base 2 from being damaged by rigid collision with the processing table 1.

[0028] A specific application of the operation process of this embodiment is as follows: In the initial state, the processing table 1 and the fixed mold base 2 are locked. When the fixed mold base 2 needs to be replaced, the motor 10 is started so that it drives the rotating shaft 7 to rotate through the bevel gear 9, which further brings the two moving seats 4 closer to each other. Thus, the smooth plate 401 and the connecting seat 5 drive the insert block 6 to separate from the insertion hole 2011. After the insert block 6 separates from the insertion hole 2011, the fixed mold base 2 is unlocked. The spring 14 drives the buffer plate 13 to push the fixed mold base 2 upward so that a gap is created between the fixed mold base 2 and the processing table 1, making it easier to remove the fixed mold base 2. When installing the new fixed mold base 2, the fixed plate 201 is inserted into the positioning through slot 101 and placed on the buffer plate 13. The buffer plate 13 causes the spring 14 to undergo elastic deformation to avoid rigid collision between the fixed plate 201 and the buffer plate 13. The spring 14 also supports the buffer plate 13 and the fixed plate 201 and creates a gap between the bottom surface of the fixed mold base 2 and the top surface of the processing table 1 to avoid rigid collision between the processing table 1 and the fixed mold base 2. Then, the drive motor 10 drives the rotating shaft 7 to rotate through the bevel gear 9, further moving the two moving seats 4 away from each other. Thus, the smooth plate 401 and the connecting seat 5 drive the insert block 6 to be inserted into the insertion hole 2011, completing the locking of the fixed mold base 2.
