[0070] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0071] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the term "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or mutual communication; it can be a direct connection or an indirect connection through an intermediate medium; it can be internal communication between two elements or an interaction between two elements. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0072] The following describes in detail various embodiments of the present invention in conjunction with the accompanying drawings.

[0073] See Figure 1 and Figure 2 The embodiment of the present invention provides a carrying mechanism 100, including a fixing member 110, a mounting member 120, a rotating member 130, an elastic member 140, a carrying member 150 and a fastener 160. The carrying mechanism 100 is used to carry powder material, and after the powder material is printed into a product, the excess powder material on the carrier is removed through the vibration of the carrying member 150 and the gravity of the powder material itself.

[0074] See Figure 1 and Figure 2The fixing member 110 is used to connect to an external printing mechanism and is provided with a pressing surface 110a. The mounting member 120 is connected to the fixing member 110. The rotating member 130 is rotatably connected to the mounting member 120, and the rotation axis of the rotating member 130 is parallel to the pressing surface 110a. The elastic member 140 is connected to the fixing member 110 and is located on the same side of the fixing member 110 as the mounting member 120. The elastic direction of the elastic member 140 is inclined relative to the pressing surface 110a. The supporting member 150 can be movably mounted on the rotating member 130 and the mounting member 120. The supporting member 150 is used to support the powder material in the printing mechanism. The fastener 160 is detachably connected to the supporting member 150 and the rotating member 130 respectively. The supporting member 150 rotates relative to the fixing member 110 under the drive of the rotating member 130, so that the supporting member 150 is in contact with the pressing surface 110a, or the supporting member 150 is abutted against the mounting member 120. When the carrier 150 abuts against the mounting member 120 , the carrier 150 presses the elastic member 140 toward the fixing member 110 , and the rotation angle of the carrier 150 relative to the abutment against the mounting member 120 is greater than 90°.

[0075] In this embodiment, the fixing member 110 and the supporting member 150 are both substantially rectangular parallelepipeds, the pressing surface 110a is a planar structure, the elastic member 140 is a spring, and the rotation angle of the supporting member 150 relative to the supporting member 150 when it abuts the mounting member 120 ranges from 113° to 115°. Specifically, the rotation angle of the supporting member 150 relative to the supporting member 150 when it abuts the mounting member 120 can be 110°, 111°, 112°, 113°, 114°, or 115°.

[0076] It should be noted that when the supporting member 150 is against the mounting member 120, the inclination angle of the supporting member 150 relative to the pressing surface 110a and the inclination angle of the elastic force direction of the elastic member 140 relative to the pressing surface 110a can be equal or different, as long as the elastic member 140 can provide a stable elastic force to the supporting member 150.

[0077] See Figure 2 and Figure 3 In some embodiments, the fixing member 110 includes a fixing body 111 and a stopper 112. A pressing surface 110a is provided on the fixing body 111. The fixing body 111 further includes a supporting surface 111a. The supporting surface 111a is inclined relative to the pressing surface 110a. The elastic member 140 is provided on the supporting surface 111a. The stopper 112 includes a stopper portion 1121 and a locking portion 1122. The stopper portion 1121 is inserted into one end of the elastic member 140 close to the supporting surface 111a. One end of the locking portion 1122 passes through the stopper portion 1121 and is threadedly connected to the supporting surface 111a. The other end of the locking portion 1122 abuts against the stopper portion 1121.

[0078] In this embodiment, the stopper 1121 is generally annular and is embedded in and coaxially disposed with the elastic member 140. The locking portion 1122 is a locking bolt. The threaded section of the locking bolt passes through the stopper 1121 and is threadedly connected to the support surface 111a, with the head of the locking bolt abutting against the stopper 1121.

[0079] In some embodiments, the fixing body 111 is provided with an elastic groove 111b, the bottom wall of which forms a support surface 111a, and a portion of the elastic member 140 is accommodated in the elastic groove 111b. Therefore, the elastic groove 111b can limit the elastic member 140, facilitating the installation of the elastic member 140.

[0080] In this embodiment, the opening of the elastic groove 111b is inclined from the pressing surface 110a to the supporting surface 111a, which can prevent the elastic groove 111d from interfering with the elastic force of the elastic member 140 when the carrier 150 presses the elastic member 140.

[0081] See Figure 3 In some embodiments, the angle α between the support surface 111a and the pressing surface 110a satisfies the relationship: 10°≤α≤20°. For example, α can be 10°, 12°, 15°, 17°, or 20°. In this embodiment, α is 15°.

[0082] Therefore, by properly setting the angle between the support surface 111a and the pressing surface 110a, the installed elastic member 140 can provide a stable elastic force. Specifically, if α is less than 10°, the requirement for the elastic member 140 to be tilted relative to the pressing surface 110a cannot be met. If α is greater than 20°, the tilt angle of the support surface 111a is too large compared to when α is less than 20°, which is not conducive to the elastic member 140 generating a stable elastic force on the carrier 150.

[0083] See Figure 2 and Figure 3 In some embodiments, there are two elastic members 140 , which are spaced apart, and the mounting member 120 is disposed between the two elastic members 140 . Therefore, the two elastic members 140 spaced apart are conducive to providing a stable elastic force for the supporting member 150 .

[0084] In this embodiment, there are two elastic grooves 111 d and two stoppers 112 , and the two elastic grooves 111 d , the two stoppers 112 and the two elastic members 140 correspond to each other one by one.

[0085] See Figure 2In some embodiments, the mounting member 120 includes two mounting bodies 121. The two mounting bodies 121 are spaced apart from and connected to the fixing member 110. One end of the rotating member 130 is movably inserted into one of the mounting bodies 121, and the other end of the rotating member 130 is movably inserted into the other mounting body 121. The fastener 160 is detachably connected to the rotating member 130 located between the two mounting bodies 121.

[0086] In this embodiment, each mounting body 121 is detachably connected to the fixing body 111 , and the two mounting bodies 121 are disposed between the two elastic grooves 111 d .

[0087] See Figure 2 and Figure 4 In some embodiments, a first movable groove 150a, a second movable groove 150b, and a third movable groove 150c are defined at one end of the carrier 150. The first movable groove 150a is configured to be sleeved onto the rotating member 130. The second movable groove 150b communicates with the first movable groove 150a and is configured to be sleeved onto the mounting member 120. The third movable groove 150c is located on a side of the second movable groove 150b facing away from the first movable groove 150a and is configured to be sleeved onto the elastic member 140. The angle between the two groove walls of the second movable groove 150b facing the mounting member 120 is obtuse, thereby providing support for the mounting member 120.

[0088] Therefore, through the above arrangement, collision of external components with the rotating member 130 , the mounting member 120 and the elastic member 140 can be avoided, which is beneficial to improving the service life of the supporting mechanism 100 .

[0089] In this embodiment, the first movable groove 150a is a linear groove, and there are two second movable grooves 150b and two third movable grooves 150c. The two second movable grooves 150b are located at both ends of the first movable groove 150a and correspond one-to-one with the two mounting bodies 121. The first movable groove 150a and the two second movable grooves 150b are located between the two third movable grooves 150c. The two third movable grooves 150c correspond one-to-one with the two elastic members 140. The two groove walls of each second movable groove 150b facing the mounting member 120 are used to abut the corresponding mounting body 121.

[0090] See Figure 2 and Figure 4In some embodiments, the supporting mechanism 100 further includes a linkage member 170, a toggle member 180, a clamping member 190, and a reset member 191. The linkage member 170 is rotatably connected to one end of the supporting member 150 away from the first movable groove 150a. The toggle member 180 is fixedly sleeved on the linkage member 170 and is used to drive the linkage member 170 to rotate. The clamping member 190 is fixedly sleeved on the linkage member 170 and is driven by the linkage member 170 to rotate. The clamping member 190 is used to clamp the end of the fixing member 110 away from the mounting member 120 when the supporting member 150 is in contact with the pressing surface 110a. One end of the reset member 191 is connected to the clamping member 190, and the other end of the reset member 191 is connected to the supporting member 150.

[0091] It should be noted that when the clamping member 190 is clamped on the fixing member 110, the state of the supporting mechanism 100 is as follows: Figure 5 As shown, the reset member 191 is in a natural state. When it is necessary to separate the supporting member 150 and the fixing member 110, force is applied to the toggle member 180. The toggle member 180 drives the holding member 190 to rotate in a direction away from the fixing member 110 through the linkage member 170. At this time, the holding member 190 stretches the reset member 191. When the supporting member 150 is pressed against the mounting member 120, the force applied to the toggle member 180 is canceled, and the holding member 190 is reset under the elastic tension of the reset member 191.

[0092] In this embodiment, the linkage member 170 includes two linkage bodies 171, two reset members 191, and two clamping members 190. Each linkage body 171 is rotatably connected to the end of the carrier 150 away from the first movable groove 150a. The two linkage bodies 171 are spaced apart. The end of each linkage body 171 closest to the other linkage body 171 is inserted into the toggle member 180, and the end of each linkage body 171 away from the other linkage body 171 is inserted into a clamping member 190. The two clamping members 190 are located at both ends of the toggle member 180, and each clamping member 190 corresponds to a reset member 191. The reset member 191 and the carrier 150, as well as the reset member 191 and the clamping member 190, can be connected by rivets.

[0093] See Figure 4In some embodiments, the end of the carrier 150 away from the first movable groove 150a defines a first receiving groove 150d and a second receiving groove 150e. The linkage member 170 movably passes through the sidewalls of the first receiving groove 150d and the second receiving groove 150e. The toggle member 180 is accommodated in the first receiving groove 150d, and the retaining member 190 is accommodated in the second receiving groove 150e. The end of the fixing member 110 away from the mounting member 120 defines a first limiting groove 110b corresponding to the first receiving groove 150d and a second limiting groove 110c corresponding to the second receiving groove 150e. The first limiting groove 110b is used to accommodate the toggle member 180 and the linkage member 170 when the carrier 150 is in contact with the pressing surface 110a. The second limiting groove 110c is used to accommodate the retaining member 190 when the carrier 150 is in contact with the pressing surface 110a.

[0094] In this embodiment, the first receiving groove 150d and the first limiting groove 110b are both strip grooves, and there are two second receiving grooves 150e and two second limiting grooves 110c. The two second receiving grooves 150e are located at both ends of the first receiving groove 150d, and the two second limiting grooves 110c are located at both ends of the first limiting groove 110b.

[0095] In the above-mentioned carrying mechanism 100, when removing excess powder material from the carrying member 150, the carrying member 150 is driven to rotate relative to the fixed member 110 under the guidance of the rotating member 130 until the carrying member 150 abuts against the mounting member 120. At this time, the carrying member 150 presses the elastic member 140 to the fixed member 110, and the rotation angle of the carrying member 150 relative to the time when the carrying member 150 abuts against the mounting member 120 is greater than 90°. The elastic force generated by the elastic member 140 on the carrying member 150 drives the carrying member 150 to shake, causing the excess powder material on the carrying member 150 to vibrate and separate from the carrying member 150 under the action of its own gravity. The labor intensity is low, thereby improving the efficiency of removing the powder material.

[0096] See Figure 6 The present invention also provides a printing device 1000, comprising a printing mechanism 200 and the carrier mechanism 100 of the above embodiment. The printing mechanism 200 comprises a workbench 210, a powder supply assembly 220, and a printing assembly 230. The fixing member 110 is connected to the workbench 210. The powder supply assembly 220 is used to provide powder material to the carrier 150 when the carrier 150 is attached to the pressing surface 110a. The printing assembly 230 is used to print a product on the powder material on the carrier 150. The printing assembly 230 may be a laser printer.

[0097] The working process of the above-mentioned printing device 1000 is roughly as follows:

[0098] First, assemble the carrier 150 and the fixing member 110 so that the clamping member 190 is clamped on the fixing member 110, so that the carrier mechanism 100 is formed as follows: Figure 5 The status shown;

[0099] Secondly, the carrying mechanism 100 is placed on the workbench 210 and is moved to a predetermined position by the workbench 210 ;

[0100] Then, the powder supply assembly 220 supplies powder material to the carrier 150 , and the printing assembly 230 prints the powder material on the carrier 150 , and this step is repeated until a product is printed.

[0101] Finally, the supporting mechanism 100 and the product are removed, and force is applied to the toggle member 180. The toggle member 180 drives the clamping member 190 to rotate in a direction away from the fixed member 110 through the linkage member 170, so that the supporting member 150 rotates relative to the fixed member 110 under the drive of the rotating member 130 until the supporting member 150 abuts against the mounting member 120 and presses the elastic member 140. The elastic force generated by the elastic member 140 on the supporting member 150 drives the supporting member 150 to shake, causing the excess powder on the supporting member 150 to vibrate and separate from the supporting member 150 under the action of its own gravity.

[0102] In the above-mentioned printing device 1000, the elastic force generated by the elastic member 140 on the supporting member 150 drives the supporting member 150 to shake, so that the excess powder material on the supporting member 150 vibrates and separates from the supporting member 150 under the action of its own gravity. The labor intensity is low, thereby improving the efficiency of removing powder material in the printing device 1000.
