Description

Technical Field

[0001] The utility model relates to the technical field of CD burning printers, and particularly relates to a CD burning printer. Background Art

[0002] A CD burning printer is a device that integrates CD data storage and CD printing. Users can burn digital information onto a CD and directly print the required text, images, barcodes, or other identification information on the surface of the CD. This device is widely used in occasions that require a large amount of data replication and distribution, such as enterprise data backup, software distribution, multimedia content production, etc.

[0003] Currently, inkjet printing technology is commonly used for CD printing. This method can produce various patterns and texts on the surface of the CD. To ensure that the patterns can be clearly printed on the CD, a special matte coating is usually applied to the surface of the CD first. The surface of this coating has tiny uneven textures, which help control the flow of ink and prevent the ink from spreading on the surface of the CD, thus enabling the printing of patterns with clear edges and vivid colors.

[0004] The microstructure of the matte coating is crucial for printing quality because it provides the adhesion and diffusion control required by the ink. In contrast, the surface of an untreated CD is too smooth and lacks sufficient texture to fix the ink, resulting in the ink being prone to sliding or flowing on the surface, which will cause the printed patterns to appear blurred. Therefore, it is not feasible to directly perform inkjet printing on the original smooth surface of the CD, and the printing suitability must be improved by applying a matte layer first.

Detailed implementation mode

[0054] The concept, specific structure and technical effects of the present utility model will be clearly and completely described below in conjunction with the embodiments and the drawings, so as to fully understand the purpose, features and effects of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts shall fall within the scope of protection of the present utility model. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components alone, but refer to the more optimal connection structure that can be formed by adding or reducing connection accessories according to the specific implementation situation. Each technical feature in the creation of the present utility model can be combined interactively without conflicting with each other.

[0055] The special matte coating on the optical disc is mainly set to facilitate inkjet printing. Since the coating material contains organic solvents, when the optical disc is just out of the factory, the continuous volatilization of the organic solvents causes the optical disc to have a pungent smell, which is harmful to the health of users. If the setting of the matte coating can be omitted, the user experience of using the optical disc can be improved.

[0056] Refer to Figures 1 - 2 , an optical disc burning printer, including a housing 10, and inside the housing 10 are provided: an optical disc transmission channel 1, one end of the optical disc transmission channel 1 is provided with an optical disc storage bin 2 and a burning component 3, and the other end of the optical disc transmission channel 1 is provided with an optical disc outlet 4;

[0057] Above the optical disc transmission channel 1 and between the burning component 3 and the optical disc outlet 4, an optical disc thermal printer head 5 and a lifting component 6 for driving the optical disc thermal printer head 5 to lift are provided.

[0058] The optical disc in the optical disc storage bin flows out. After the burning component burns digital information onto the optical disc, the thermal printing head of the optical disc can directly print patterns and texts on the smooth surface of the optical disc without pre-coating a matte layer;

[0059] Through thermal printing, a clear coating can be printed on the smooth optical disc; and it is also not necessary to wait for the coating to dry before putting it into application, which is convenient and fast;

[0060] The function of this optical disc burner is not only limited to printing on smooth optical discs, and even matte coatings can be applied.

[0061] Referring to Figure 2 、 Figure 7 and Figure 8 Furthermore, the thermal printing head 5 of the optical disc includes a thermal film 51 arranged in the direction of the optical disc transmission channel 1, a first carbon ribbon roller 52 arranged at the front end of the thermal film 51, and a second carbon ribbon roller 53 arranged at the rear end of the thermal film 51.

[0062] When printing the optical disc through the optical disc transmission channel 1, if the supply path of the carbon ribbon deviates, it may cause undue distortion of the carbon ribbon at the thermal printing head 5 of the optical disc. The distortion of the carbon ribbon will not only reduce the quality of the printed image, but may also cause blurring or misalignment of the printed content, thereby affecting the final printing effect; by setting the first carbon ribbon roller 52 and the second carbon ribbon roller 53, the front end of the carbon ribbon is restricted between the front side of the thermal printing head 5 of the optical disc and the first carbon ribbon roller 52, and at the same time, the rear end of the carbon ribbon is restricted between the rear side of the thermal printing head 5 of the optical disc and the same carbon ribbon roller 52; thus ensuring that the carbon ribbon remains straight at the thermal printing head 5 of the optical disc, preventing it from being distorted or deformed, and thus ensuring the stability of the carbon ribbon during the printing process and the consistency of the printing quality.

[0063] Referring to Figure 2 Specifically, a feeding roller 13 is rotatably arranged below the thermal printing head 5 of the optical disc; the thermal film 51 is arranged obliquely relative to the axis of the feeding roller 13. The contact area between the thermal film 51 and the optical disc is reduced, and the printing effect is optimized.

[0064] Referring to Figure 3 、 Figure 6 、 Figure 7 and Figure 8 Furthermore, a first support plate 71 and a second support plate 72 are arranged on both sides of the optical disc transmission channel 1;

[0065] The lifting component 6 includes a mounting plate 611, a top plate 612, a bottom plate 613, a slide rail 61, a lead screw 631, a first elastic member 632, a sliding pressure plate 633, and a lower fixing plate 643;

[0066] The mounting plate 611 is perpendicular to the optical disc transmission channel 1, with one side fixed to the first support plate 71 and the other side fixed to the second support plate 72.

[0067] The top plate 612 is fixed to the top of the mounting plate 611, and the bottom plate 613 is fixed to the bottom of the mounting plate 611.

[0068] The slide rail 61 is fixed to the mounting plate 611 and is arranged perpendicular to the optical disc transmission channel 1.

[0069] One end of the lead screw 631 is rotatably connected to the top plate 612, and the other end of the lead screw 631 is rotatably connected to the bottom plate 613, and the lead screw 631 is parallel to the slide rail 61.

[0070] Both the sliding pressure plate 633 and the lower fixing plate 643 are slidably arranged on the slide rail 61; the sliding pressure plate 633 can be in rolling connection with the lead screw 631; specifically, a lead screw nut can be arranged in the sliding pressure plate 633, and the lead screw nut is fixedly connected to the sliding pressure plate 633, so that when the lead screw 631 rotates, the sliding pressure plate 633 moves along the axial direction of the lead screw 631; alternatively, one end of the sliding pressure plate 633 is fixedly connected with a lead screw nut 634 with a certain length, and the height of the lead screw nut 634 is greater than the height after the first elastic member 632 is completely compressed, so as to ensure that after the first elastic member 632 is compressed, it does not reach its maximum compression stroke, and thus still has a certain elasticity.

[0071] The first elastic member 632 is sleeved on the lead screw 631, and one end of the first elastic member 632 abuts against the sliding pressure plate 633, and the other end abuts against the lower fixing plate 643.

[0072] The rotation of the lead screw 631 drives the sliding pressure plate 633 to press down the lower fixing plate 643, so that the optical disc thermal printing head 5 moves up and down relative to the optical disc transmission channel 1.

[0073] Among them, the function of the bottom plate 613 is on the one hand to fix the lead screw 631, and on the other hand to limit the lowest position of the up and down movement of the lower fixing plate 643 and the optical disc thermal printing head 5.

[0074] The function of the slide rail 61 is to enable the sliding pressure plate 633, the lower fixing plate 643 and the optical disc thermal printing head 5 to move up and down smoothly.

[0075] Refer to Figure 6, The sliding pressure plate 633 is located above the lower fixed plate 643. When the height of the optical disc thermal printing head 5 needs to be adjusted, by rotating the lead screw 631, the sliding pressure plate 633 can be driven to move horizontally along the slide rail 61. During this process, the sliding pressure plate 633 applies a downward force on the first elastic member 632, prompting the first elastic member 632 and the lower fixed plate 643 to move together in the direction of the optical disc transmission channel 1.

[0076] When the lower fixed plate 643 moves to contact the bottom plate 613, if the lead screw 631 continues to rotate, the sliding pressure plate 633 and the lower fixed plate 643 will jointly apply pressure to the first elastic member 632. At this time, the first elastic member 632 has a certain degree of elasticity and allows a certain degree of deformation.

[0077] When the lead screw 631 stops rotating and the height adjustment of the optical disc thermal printing head 5 is completed; when there is an optical disc passing through the optical disc transmission channel 1 and the optical disc moves below the optical disc thermal printing head 5, the optical disc will apply a downward force on the optical disc thermal printing head 5, and this force will be transmitted to the lower fixed plate 643. At this time, since the position of the sliding pressure plate 633 is fixed, the lower fixed plate 643 will apply an upward force on the first elastic member 632, squeezing the first elastic member 632. The action of this force enables the optical disc thermal printing head 5 to have a certain degree of floating property, thus avoiding direct rigid contact with the optical disc and reducing possible wear on the surface of the optical disc due to excessive pressure from the printing head.

[0078] Refer to Figure 3 and Figure 7 , Specifically, the lifting assembly 6 further includes a lead screw driving member 651 with a fixed end provided on the first support plate 71;

[0079] A worm gear transmission group 652 is provided between the lead screw driving member 651 and the lead screw 631. Worm gear transmission can provide high torque density, that is, provide a large torque output in a smaller space, which makes the structure of the optical disc burning printer more compact and reduces the volume of the optical disc burning printer.

[0080] Refer to Figure 7 , Specifically, the worm gear transmission group 652 includes a worm wheel 653 provided on the lead screw 631 and a worm 654 provided on the output end of the lead screw driving member 651.

[0081] More specifically, along the width direction of the optical disc transmission channel 1, the slide rail 61 is provided at the middle position of the optical disc transmission channel 1.

[0082] More specifically, the lifting assembly 6 further includes an upper fixing plate 641 disposed above the lower fixing plate 643, and a connecting member 642 disposed between the upper fixing plate 641 and the lower fixing plate 643 and fixedly connected to the upper fixing plate 641 and the lower fixing plate 643;

[0083] The upper fixing plate 641 is slidably disposed on the slide rail 61;

[0084] The sliding pressure plate 633 is disposed between the upper fixing plate 641 and the lower fixing plate 643.

[0085] More specifically, the lifting assembly 6 further includes a first guiding member 661 and a second guiding member 662;

[0086] The first guiding member 661 and the second guiding member 662 are respectively disposed on both sides of the slide rail 61, and one end of each of them is fixed to the upper fixing plate 641, and the other end is fixed to the lower fixing plate 643;

[0087] The sliding pressure plate 633 can slide on the first guiding member 661 and the second guiding member 662, assisting the sliding pressure plate 633 to be able to move smoothly along a predetermined path, reducing the vibration or deviation that may be caused by the skew or uneven force of the sliding pressure plate 633.

[0088] More specifically, along the length direction of the optical disc transmission channel 1, a carbon ribbon winding roller 81 is disposed on the front side of the optical disc thermal printer head 5, and a carbon ribbon unwinding roller 82 is disposed on the rear side;

[0089] Refer to Figure 3 , a winding driving member 811 for driving the carbon ribbon winding roller 81 to wind is disposed on the first support plate 71;

[0090] The fixed end of the winding driving member 811 is disposed on the side of the first support plate 71 facing the optical disc transmission channel 1, and the output end of the winding driving member 811 passes through the first support plate 71 and is connected with a driving wheel 812;

[0091] Refer to Figures 3 - 5 , the end of the carbon ribbon winding roller 81 passes through the first support plate 71, and a one-way driven wheel 813 is connected to the end of the carbon ribbon winding roller 81;

[0092] A transmission belt (not shown in the figure) is engaged with both the driving wheel 812 and the one-way driven wheel 813; the winding driving member 811 is disposed on one side of the optical disc transmission channel 1, which can reduce the floor area of the optical disc printer and reduce its volume.

[0093] More specifically, the carbon ribbon winding roller 81 includes a rotating shaft 815 passing through the first support plate 71 and an end shaft 816 coaxially arranged with the rotating shaft 815. The end shaft 816 is arranged on the side of the rotating shaft 815 away from the carbon ribbon winding roller 81 and is fixedly connected to the rotating shaft 815;

[0094] The diameter of the rotating shaft 815 is larger than the diameter of the end shaft 816;

[0095] The one-way driven wheel 813 is arranged on the end shaft 816. A damping member 817 and an inner member 820 are arranged between the rotating shaft 815 and the one-way driven wheel 813;

[0096] The inner member 820 is fixedly connected to the rotating shaft 815, and the damping member 817 is arranged between the inner member 820 and the one-way driven wheel 813;

[0097] A pre-tightening nut 818 is arranged at one end of the end shaft 816 away from the rotating shaft 815, and an external thread threadedly engaged with the pre-tightening nut 818 is arranged on the end shaft 816;

[0098] A second elastic member 819 is sleeved on the end shaft 816, and the second elastic member 819 is located between the pre-tightening nut 818 and the one-way driven wheel 813;

[0099] Rotating the pre-tightening nut 818 to compress / relax the second elastic member 819 can drive the one-way driven wheel 813 to move towards the inner member 820 / move away from the inner member 820, compress / relax the damping member 817, thereby adjusting the friction force between the damping member 817 and the inner member 820 and the one-way driven wheel 813.

[0100] Specifically, the outer circle of the end shaft 816 is D-shaped, and the inner circle of the inner member 820 is a D-shaped hole matching the end shaft 816. Therefore, the inner member 820 will not slide relative to the end shaft 816, and the rotation of the inner member 820 can drive the end shaft 816 and the rotating shaft 815 to rotate synchronously;

[0101] More specifically, the inner member 820 is a metal part.

[0102] Specifically, a one-way bearing is arranged inside the one-way driven wheel 813, and the one-way driven wheel 813 can only rotate in one direction relative to the rotating shaft 815. Therefore, the winding driving member 811 can drive the carbon ribbon winding roller 81 to rotate in one direction towards the direction of tightening the carbon ribbon by relying on the friction force of the damping member 817. When the winding driving member 811 stops rotating, the carbon ribbon winding roller 81 will not loosen the carbon ribbon.

[0103] The working principle of the structure of this embodiment is as follows:

[0104] When the pre-tightening nut 818 is rotated to squeeze (relax) the second elastic member 819, under the action of the elastic force of the second elastic member 819, the one-way driven wheel 813 moves toward (away from) the rotating shaft 815, thereby controlling the degree of fitting between the damping member 817 and the inner member 820 and the one-way driven wheel 813, and controlling the magnitude of the frictional force between the damping member 817 and the inner member 820 and the one-way driven wheel 813. Two kinds of motion conditions will occur in this process:

[0105] First: When the frictional force F1 generated by the damping member 817 on the inner member 820 and the one-way driven wheel 813 is greater than or equal to the frictional force F2 between the transmission belt and the one-way driven wheel 813, the winding driving member 71 drives the transmission belt to rotate, and the damping member 817, the inner member 820, and the one-way driven wheel 813 rotate synchronously, driving the carbon ribbon winding roller 81 to rotate synchronously;

[0106] Second: When the frictional force F1 generated by the damping member 817 on the inner member 820 and the one-way driven wheel 813 is less than the frictional force F2 between the transmission belt and the one-way driven wheel 813, the winding driving member 71 drives the transmission belt to rotate, and the one-way driven wheel 813 slips relative to the damping member 817 and the connecting shaft 612. The one-way driven wheel 813, the winding driving member 71, and the transmission belt can rotate normally, while the carbon ribbon winding roller 81 remains in a relatively stationary state; this helps to maintain the tension of the carbon ribbon, and when the carbon ribbon is almost used up, it can prevent the carbon ribbon winding roller 81 from breaking the carbon ribbon.

[0107] This design causes relative sliding between the inner member 820, the damping member 817, and the one-way driven wheel 813. The one-way driven wheel 813 always rotates with the driving wheel 812, and the carbon ribbon winding roller 81 always rotates with the inner member 820. In this way, even if the driving wheel 812 continues to rotate, the carbon ribbon winding roller 81 can remain stable and maintain an appropriate tension of the carbon ribbon. Especially when the carbon ribbon is nearly used up, this mechanism can prevent the carbon ribbon winding roller 81 from breaking the carbon ribbon due to excessive pulling, ensuring the continuity of the printing process and the integrity of the carbon ribbon.

[0108] Specifically, the second elastic member 819 is a spring, and the damping member 817 is a wool felt.

[0109] The above is a specific description of the preferred embodiment of the present invention, but the present invention is not limited to the described embodiment.
