Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.

[0019] Please see Figure 1-7An embossing device according to an embodiment of the present invention includes a driving component, a first embossing roller 1, a second embossing roller 2, a first rotating gear 3, a second rotating gear 4, a first support component, a second support component, a first rotating shaft 5 rotatably connected to the first support component at its center, and a second rotating shaft 6 rotatably connected to the second support component at its center. The first rotating gear 3 includes a first base 31 sleeved on a first portion of the first rotating shaft 5 and a plurality of first teeth 32 circumferentially disposed on the side of the first base 31. The second rotating gear 4 includes a second base 41 sleeved on a first portion of the second rotating shaft 6 at its center, and a plurality of second teeth 42 and a plurality of third teeth 42 respectively circumferentially disposed on the side of the second base 41. The first rotating shaft 5 is fitted with a tooth 43, and the second part of the first rotating shaft 5 is fitted with a first impression roller 1. The second part of the second rotating shaft 6 is fitted with a second impression roller 2. The driving component is connected to one of the first rotating shaft 5 and the second rotating shaft 6 to drive one of the first rotating shaft 5 and the second rotating shaft 6 to rotate. Multiple second teeth 42 and multiple third teeth 43 are respectively arranged in a one-to-one correspondence with multiple first teeth 32, and multiple second teeth 42 and multiple third teeth 43 are arranged in a staggered manner. When the distance between the first base 31 and the second base 41 is within a preset range, multiple first teeth 32 respectively cooperate with multiple second teeth 42 and multiple third teeth 43, so that the first rotating gear 3 meshes with the second rotating gear 4.

[0020] Here, the first rotating shaft 5 is rotatably connected to the first support member, and the second rotating shaft 6 is rotatably connected to the second support member, so that the first support member supports the first rotating shaft 5 and the second support member supports the second rotating shaft 6. The first part of the first rotating shaft 5 is sleeved on the middle of the first base 31 and the second part is sleeved on the first impression roller 1. When the first rotating shaft 5 rotates, it can drive the first rotating gear 3 and the first impression roller 1 to rotate respectively. The first part of the second rotating shaft 6 is sleeved on the middle of the second base 41 and the second part is sleeved on the second impression roller 2. When the second rotating shaft 6 rotates, it can drive the second rotating gear 4 and the second impression roller 2 to rotate respectively. The driving component is connected to one of the first rotating shaft 5 and the second rotating shaft 6 to drive one of the first rotating shaft 5 and the second rotating shaft 6 to rotate. That is, when the driving component is connected to the first rotating shaft 5, the driving component drives the first rotating shaft 5 to rotate; when the driving component is connected to the second rotating shaft 6, the driving component drives the second rotating shaft 6 to rotate. When the driving component drives the first rotating shaft 5 to rotate, the first rotating shaft 5 can drive the first rotating gear 3 and the first impression roller 1 to rotate. The first rotating gear 3 can drive the second rotating gear 4 meshing with it to rotate. The second rotating gear 4 can drive the second rotating shaft 6 to rotate. The second rotating shaft 6 can drive the second impression roller 2 to rotate. When the driving component drives the second rotating shaft 6 to rotate, the second rotating shaft 6 can drive the second rotating gear 4 and the second impression roller 2 to rotate. The second rotating gear 4 can drive the first rotating gear 3 meshing with it to rotate. The first rotating gear 3 can drive the first rotating shaft 5 to rotate. The first rotating shaft 5 drives the first impression roller 1 to rotate. An impression gap is provided between the first impression roller 1 and the second impression roller 2 for the object to be printed to pass through. When the first impression roller 1 and the second impression roller 2 rotate and the object to be printed passes through the impression gap, the combined action of the first impression roller 1 and the second impression roller 2 imprints a pattern onto the object to be printed.

[0021] Specifically, to achieve different imprinting effects on a substrate, different degrees of imprinting are required, necessitating adjustment of the distance between the first imprint roller 1 and the second imprint roller 2. Similarly, when imprinting patterns of varying thicknesses to different depths, the distance between the first imprint roller 1 and the second imprint roller 2 needs adjustment. Furthermore, when imprinting patterns onto different types of substrates of varying thicknesses, the distance between the first imprint roller 1 and the second imprint roller 2 also needs adjustment. When adjusting the distance between the first imprint roller 1 and the second imprint roller 2, the distance between the first rotating shaft 5 and the second rotating shaft 6 is adjusted, and correspondingly, the distance between the first substrate 31 and the second substrate 41 is adjusted. Therefore, when the distance between the first substrate 31 and the second substrate 41 is adjusted within a preset range, the distance between the first imprint roller 1 and the second imprint roller 2 can be adjusted accordingly. According to the adjustment, when the distance between the first substrate 31 and the second substrate 41 is within a preset range, multiple first teeth 32 are respectively matched with multiple second teeth 42 and multiple third teeth 43. The multiple first teeth 32 engage with the multiple second teeth 42 and the multiple third teeth 43, allowing the first rotating gear 3 to mesh with the second rotating gear 4. When one of the first rotating gear 3 or the second rotating gear 4 is driven by a driving component, it can drive the other of the first rotating gear 3 or the second rotating gear 4 to rotate. The first rotating gear 3 can drive the first rotating shaft 5 to rotate, and the second rotating gear 4 can drive the second rotating shaft 6 to rotate. The first rotating shaft 5 drives the first impression roller 1 to rotate, and the second rotating shaft 6 drives the second impression roller 2 to rotate. This ensures that the first impression roller 1 and the second impression roller 2 work together to imprint the material to be printed, forming a pattern of corresponding depth on the material. This application does not require replacing one of the first rotating gear 3 or the second rotating gear 4, or both of the first rotating gear 3 and the second rotating gear 4, making operation convenient and improving the efficiency of the imprinting process.

[0022] Specifically, the drive structure may include a drive motor, the output shaft of which is connected to one of the first rotating shaft 5 and the second rotating shaft 6.

[0023] Multiple second teeth 42 can be set in one-to-one correspondence with multiple third teeth 43, and the distance between the axis of any second tooth 42 and the axis of the third tooth 43 corresponding to that second tooth 42 is the same; multiple first teeth 32, multiple second teeth 42 and multiple third teeth 43 are all set at equal intervals.

[0024] Specifically, multiple first teeth 32, multiple second teeth 42, and multiple third teeth 43 are all equidistantly arranged, that is, multiple first teeth 32, multiple second teeth 42, and multiple third teeth 43 are equidistantly arranged. With multiple first teeth 32 equidistantly arranged, the distance between any two adjacent first teeth 32 is the same. With multiple second teeth 42 equidistantly arranged, the distance between any two adjacent second teeth 42 is the same. With multiple third teeth 43 equidistantly arranged, the distance between any two adjacent third teeth 43 is the same. Multiple first teeth 32 are evenly arranged on the side surface of the first substrate 31, multiple second teeth 42 are evenly arranged on the side surface of the second substrate 41, and multiple third teeth 43 are evenly arranged on the side surface of the second substrate 41. Each of the multiple second teeth 42 and multiple third teeth 43 corresponds one-to-one with a single first tooth 32, and the number of second teeth 42 and the number of third teeth 43 are the same as the number of first teeth 32. Multiple second teeth 42 and multiple third teeth 43 are arranged in a staggered manner, with each of the multiple second teeth 42 and multiple third teeth 43 corresponding to one another. The distance between the axis of any second tooth 42 and the axis of the third tooth 43 corresponding to that second tooth 42 is the same, so that the multiple first teeth 32 can better cooperate with the multiple second teeth 42 and multiple third teeth 43 respectively, ensuring that the first rotating gear 3 can mesh with the second rotating gear 4.

[0025] The length of the second tooth 42 and the length of its corresponding third tooth 43 can be equal to the length of the first tooth 32 corresponding to the second tooth 42.

[0026] Specifically, the axis of the first tooth 32 is parallel to the axis of the first base 31, and the axes of the second tooth 42 and the third tooth 43 are both parallel to the axis of the second base 41. The axis of the second base 41 is parallel to the axis of the first base 31. Therefore, the axes of the first tooth 32, the second tooth 42, and the third tooth 43 are arranged in parallel. The sum of the length of the second tooth 42 and the length of its corresponding third tooth 43 is equal to the length of the first tooth 32 corresponding to the second tooth 42. Thus, the second tooth 42, the third tooth 43 corresponding to the second tooth 42, and the first tooth 32 corresponding to the second tooth 42 can better mesh, allowing the first rotating gear 3 to better mesh with the second rotating gear 4, thereby improving the stability of the connection between the first rotating gear 3 and the second rotating gear 4.

[0027] The length of the second tooth 42 can be equal to the length of its corresponding third tooth 43.

[0028] Specifically, the length of the second tooth 42 can be equal to the length of the corresponding third tooth 43, so that the second tooth 42, the third tooth 43 corresponding to the second tooth 42 and the first tooth 32 corresponding to the second tooth 42 can better cooperate, so that the first rotating gear 3 can better mesh with the second rotating gear 4, thereby improving the stability of the connection between the first rotating gear 3 and the second rotating gear 4.

[0029] The axis of the first rotating shaft 5 and the axis of the first substrate 31 can coincide with the axis of the first impression roller 1. The axis of the second rotating shaft 6, the axis of the second substrate 41, and the axis of the second impression roller 2 coincide. The axis of the second substrate 41 is parallel to the axis of the first substrate 31. The axis of the first tooth 32 is parallel to the axis of the first substrate 31. The axes of the second tooth 42 and the third tooth 43 are both parallel to the axis of the second substrate 41.

[0030] Specifically, the axis of the second substrate 41 is parallel to the axis of the first substrate 31, the axis of the second impression roller 2 is parallel to the axis of the first impression roller 1, and the axis of the second rotating shaft 6 is parallel to the axis of the first rotating shaft 5. The axes of the second tooth 42 and the third tooth 43 are both parallel to the axis of the first tooth 32.

[0031] As one of the imprinting devices in this embodiment, it may also include a position adjustment member connected to the first support member; the position adjustment member is used to drive the first support member to move a preset distance toward or away from the second support member to adjust the distance between the first imprinting roller 1 and the second imprinting roller 2, and the first rotating gear 3 engages with the second rotating gear 4 when the first support member has completed its movement.

[0032] Specifically, the position adjustment component is connected to the first support component. The position adjustment component moves the first support component a preset distance closer to or further away from the second support component, which in turn moves the first substrate 31 closer to or further away from the second substrate 41, and the first impression roller 1 closer to or further away from the second impression roller 2, thereby adjusting the distance between the first impression roller 1 and the second impression roller 2. The position adjustment component moving the first support component a preset distance closer to or further away from the second support component also moves the first substrate 31 a corresponding distance closer to or further away from the second substrate 41, thus adjusting the distance between the first substrate 31 and the second substrate 41 within a preset range. After the first support component is adjusted, the first rotating gear 3 meshes with the second rotating gear 4.

[0033] The first support member may include a slide rail 92, a slider 93 slidably connected to the slide rail 92 at its bottom, and a first mounting block 91 connected to the top of the slider 93.

The first part of the second rotating shaft 6 is rotatably connected to the second mounting block 94, the second part is fitted onto the second impression roller 2, and the third part is fitted onto the second base 41. The position adjustment member is connected to the first mounting block 91 to drive the first mounting block 91 to move along the direction of approaching or moving away from the corresponding second mounting block 94 to adjust the distance between the first impression roller 1 and the second impression roller 2. The first rotating gear 3 meshes with the second rotating gear 4 when the first mounting block 91 has finished moving.

The first part of the first rotating shaft 5 is sleeved on the inner ring of the first bearing, thereby realizing the rotatable connection of the first rotating shaft 5 to the first mounting block 91. The second support member also includes a second fixing hole through the second mounting block 94 and a second bearing installed at the second fixing hole. The first part of the second rotating shaft 6 is sleeved on the inner ring of the second bearing, thereby realizing the rotatable connection of the first part of the second rotating shaft 6 to the second mounting block 94.

[0036] The position adjustment component may include a cylinder 71 and a connecting plate 72, one end of the connecting plate 72 being connected to the first mounting block 91, and the output end of the cylinder 71 being connected to the other end of the connecting plate 72.
