Description

Technical Field

[0001] This utility model belongs to the field of 3D printing equipment manufacturing technology, specifically relating to a powder bucket quick assembly component. Background Technology

[0002] In selective laser sintering (SLS) printing, when the powder used for printing becomes insufficient, new powder needs to be added to the powder mixing tank to thoroughly mix with the remaining old powder, ensuring continuous and stable printing. Currently, there are several common operating methods and related technologies for adding new powder to the powder tank, but these methods all have certain limitations.

[0003] One common operating method is for the operator to directly pour powder from another powder storage bottle into the powder mixing tank through the large opening to the small opening. Because the powder is not sealed during pouring, it easily becomes airborne, creating dust, polluting the environment, harming human health, and wasting resources. Another technical solution is to use a screw-on quick-release system to add powder. In practice, rotating the powder bottle punctures the thin film at the opening, releasing the powder. However, this screw-on quick-release method has low limiting sensitivity in practical applications, lacks clear guidance and positioning, and the rotation angle is difficult to control. It is easy to completely puncture the film at the powder bottle opening, causing the film to fall into the printing system and affecting the use of the printing equipment. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art, and to provide a quick assembly component for powder containers. The structure is ingenious and reasonable, with strong practicality. The entire operation is completely sealed, eliminating the risk of powder leakage and reducing environmental pollution. Moreover, the use of a screw-lock structure makes the positioning more accurate, which can realize the directional and angled rotation of the powder bottle. While the powder bottle is rotated into place and locked, the wall-breaking needle accurately punctures the membrane to release the powder, while avoiding excessive puncture and falling of the membrane, thus improving practicality and operability.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] The powder hopper quick assembly assembly includes a powder bottle, a powder hopper, and a screw-lock structure. The powder bottle is used to store powder, and a thin film is sealed at the discharge port of the powder bottle. The powder hopper is equipped with a discharge guide groove and a wall-breaking needle. The discharge guide groove is used to guide the powder bottle to be inserted vertically into the powder hopper, and the wall-breaking needle is used to puncture the thin film. The screw-lock structure is set between the powder bottle and the powder hopper to enable the powder bottle to rotate at a fixed angle within the discharge guide groove.

[0007] After the powder bottle is inserted into the discharge guide groove, the breaking needle punctures the membrane, and the powder bottle is rotated. The powder bottle rotates at an angle α and locks with the powder container. Simultaneously, the breaking needle rotates at an angle α along the edge of the membrane, releasing the powder. The overall structure is ingeniously and rationally designed, highly practical, and the entire operation is completely sealed, eliminating the risk of powder leakage and reducing environmental pollution. The use of a snap-lock structure ensures more accurate positioning, allowing for directional and angled rotation of the powder bottle. As the powder bottle rotates into position and locks, the breaking needle precisely punctures the membrane, releasing the powder, while avoiding excessive puncture and breakage of the membrane, thus improving practicality and operability.

[0008] Furthermore, the screw-lock structure includes a spiral guide groove, a spiral buckle, and a limiting buckle. The spiral guide groove is located on the outer wall of the material inlet, the spiral buckle is located on the inner wall of the material guide groove, and the limiting buckle is located at the end of the spiral guide groove. When locking the powder bottle, the spiral buckle rotates along the spiral guide groove. When the limiting buckle engages with the spiral buckle, the powder bottle is locked in place. The structure is cleverly and reasonably designed. The spiral guide groove provides a clear guiding path for the rotation of the powder bottle, ensuring that the powder bottle accurately reaches the designated position and avoiding locking failure or inaccurate positioning of the breaking needle due to positional errors. When the limiting buckle engages with the spiral buckle, a sound will be emitted to indicate that the rotation is in place. The engagement of the two can provide a stable locking force, ensuring that the powder bottle will not loosen or fall off in the locked state, ensuring stability and reliability during operation. This design also facilitates actual operation and improves work efficiency.

[0009] Furthermore, the spiral buckle is equipped with a groove. When the powder bottle is screwed into place, the limiting buckle engages in the groove. The groove provides a clear engagement position for the limiting buckle. When the powder bottle is locked in place, the limiting buckle is precisely embedded in the groove, forming a stable engagement and improving locking reliability. Moreover, when the limiting buckle is embedded in the groove, the operator can obtain clear feedback by touch, hearing a sound and feeling a change in resistance, quickly confirming whether the powder bottle has been rotated into place, reducing operational uncertainty and preventing the limiting buckle from being incompletely engaged or over-rotated. When disassembling, the operator only needs to apply reverse force to rotate the powder bottle, causing the limiting buckle to disengage from the groove, and then it can be completely disassembled.

[0010] Furthermore, the spiral guide groove includes a spiral guide section and a vertical guide section. The spiral guide section is set along the outer wall of the discharge port. Both the end and the beginning of the spiral guide section are closed structures, and a limiting buckle is provided at the end. The vertical guide section is located on the side of the beginning of the spiral guide section. One end of the vertical guide section is connected to the spiral guide section, and the other end is an open structure. The structure is compact and reasonable. When the powder bottle is vertically inserted into the discharge guide groove, the spiral buckle passes through the corresponding vertical guide section and enters the spiral guide section. The vertical guide section cooperates with the spiral buckle to achieve precise insertion and positioning of the powder bottle in the discharge guide groove. The spiral buckle enters the spiral guide section and rotates from the beginning to the end, engaging with the limiting buckle at the end to ensure that the powder bottle is locked in place and securely locked. The spiral guide groove with closed structures at both ends is designed with a specific path for the powder bottle to rotate, realizing the directional and angled rotation of the powder bottle. When locking, the powder bottle can only rotate from the beginning to the end, and when disassembling, the powder bottle can only rotate from the end to the beginning. The angle and direction are limited.

[0011] Furthermore, a raised ring is provided on the top surface of the powder hopper, which is located on the outside of the inlet of the material guide groove. A contact ring groove is formed between the raised ring and the powder hopper. A positioning insert ring is provided on the powder bottle. When the powder bottle is installed into the powder hopper, the positioning insert ring is matched and engaged in the contact ring groove. The positioning insert ring and the contact ring groove cooperate to provide initial guidance for the insertion of the powder bottle, making it easier for the operator to insert the powder bottle into the material guide groove. It can also improve the assembly stability between the powder bottle and the powder hopper and effectively prevent the powder bottle from shaking or falling off during operation.

[0012] Furthermore, the positioning ring is provided with a sealing groove, and a sealing gasket is provided in the sealing groove. When the powder bottle is installed into the powder bucket, the sealing gasket abuts against the end face of the contact ring groove, forming an additional sealing layer. Based on the snap-fit ​​connection between the powder bottle and the powder bucket, the sealing performance at the connection between the two is further enhanced, effectively preventing powder leakage and protecting the operating environment.

[0013] Furthermore, a positioning rod is provided at the outlet of the material guide channel. The end of the positioning rod is fixedly connected to the inner side wall of the material guide channel. The wall-breaking needle is located on the positioning rod near the powder bottle. Preferably, a wall-breaking needle is provided at both ends of the positioning rod on the side relatively close to the powder bottle. The positioning rod provides a stable support structure for the wall-breaking needle, ensuring that the wall-breaking needle can maintain an accurate position and direction when piercing the film, thereby improving the piercing efficiency.

[0014] Furthermore, an arc-shaped reinforcing part is provided between the positioning rod and the inner wall of the material dropping guide groove. The arc-shaped reinforcing part and the positioning rod are integrally formed. The arc-shaped reinforcing part can enhance the connection strength between the positioning rod and the material dropping guide groove, improve the load-bearing capacity of the positioning rod, and the integral design of the arc-shaped reinforcing part and the positioning rod facilitates actual processing and forming, and can further enhance the overall structural stability.

[0015] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0016] This utility model features a clever and reasonable structural design with high practicality. The entire operation is completely enclosed, eliminating the risk of powder leakage and reducing environmental pollution. The use of a screw-lock structure ensures more accurate positioning, allowing for directional and angled rotation of the powder bottle. As the powder bottle rotates and locks in place, the breaking needle precisely punctures the membrane, releasing the powder while preventing excessive puncture and drop of the membrane, thus improving practicality and operability. In actual operation, the powder bottle is vertically inserted into the discharge guide groove. The spiral buckle enters the corresponding spiral guide section from the vertical inlet section. Rotating from the beginning to the end of the spiral guide section, a sound will be heard and resistance will be felt. At this point, the spiral buckle engages with the limiting buckle, locking the powder bottle in place. The membrane attached to the powder bottle's discharge port is also precisely punctured by the breaking needle, preventing the membrane from falling off. The powder can then fall out. After the powder has completely fallen, the powder bottle is rotated in the opposite direction, causing the spiral buckle to disengage from the limiting buckle. Rotating from the end to the beginning of the spiral guide section, the powder bottle is then lifted vertically, completing the disassembly operation. Attached Figure Description

Detailed Implementation

[0026] like Figures 1 to 7 As shown, this utility model's quick assembly assembly for a powder container includes a powder bottle 1, a powder container 2, and a screw-lock structure. The powder bottle 1 is used to store powder, and a thin film is sealed at the discharge port 18 of the powder bottle 1. The powder container 2 is provided with a discharge guide groove 3 and a wall-breaking needle 4. The discharge guide groove 3 guides the powder bottle 1 to be vertically inserted into the powder container 2, and the wall-breaking needle 4 punctures the thin film. The screw-lock structure is located between the powder bottle and the powder container to enable the powder bottle 1 to rotate at a fixed angle within the discharge guide groove 3. After the powder bottle 1 is vertically inserted into the discharge guide groove 3, the wall-breaking needle 4 punctures the thin film, and the powder bottle 1 is rotated. The powder bottle 1 rotates at an angle α and locks with the powder container 2. At the same time, the wall-breaking needle 4 rotates synchronously at an angle α along the edge of the thin film, releasing the powder. The overall structural design of this application is ingenious and reasonable, with strong practicality. The entire operation is completely sealed, eliminating the risk of powder leakage and reducing environmental pollution. The use of a screw-lock structure makes the positioning more accurate, allowing the powder bottle 1 to rotate in a directional and angled manner. While the powder bottle 1 is rotated into place and locked, the wall-breaking needle 4 precisely punctures the membrane to release the powder, while avoiding excessive puncture and falling of the membrane, thus improving practicality and operability.

[0027] A raised ring 5 is provided on the top surface of the powder bucket 2. The raised ring 5 is located on the outside of the inlet of the discharge guide groove 3, and a contact ring groove 6 is formed between the raised ring 5 and the powder bucket 2. A positioning insert ring 7 is provided on the powder bottle 1. When the powder bottle 1 is installed into the powder bucket 2, the positioning insert ring 7 is matched and snapped into the contact ring groove 6. The positioning insert ring 7 and the contact ring groove 6 cooperate to provide initial guidance for the insertion of the powder bottle 1, making it easier for the operator to insert the powder bottle 1 into the discharge guide groove 3. It can also improve the assembly stability between the powder bottle 1 and the powder bucket 2, effectively preventing the powder bottle 1 from shaking or falling off during operation. A sealing groove 8 is provided on the positioning insert ring 7, and a sealing gasket 9 is provided in the sealing groove 8. When the powder bottle 1 is installed into the powder bucket 2, the sealing gasket 9 abuts against the end face of the contact ring groove 6, forming an additional sealing layer. On the basis of the snapping of the powder bottle 1 and the powder bucket 2, the sealing performance at the connection between the two is further enhanced, effectively preventing powder leakage and protecting the operating environment.

[0028] A positioning rod 10 is provided at the outlet of the material guide groove 3. The end of the positioning rod 10 is fixedly connected to the inner wall of the material guide groove 3. A wall-breaking needle 4 is provided on the positioning rod 10 on the side relatively close to the powder bottle 1. Preferably, a wall-breaking needle 4 is provided at both ends of the positioning rod 10 on the side relatively close to the powder bottle 1. The positioning rod 10 provides a stable support structure for the wall-breaking needle 4, ensuring that the wall-breaking needle 4 can maintain an accurate position and direction when piercing the film, thereby improving the piercing efficiency. An arc-shaped reinforcing part 11 is provided between the positioning rod 10 and the inner wall of the material guide groove 3. The arc-shaped reinforcing part 11 and the positioning rod 10 are integrally formed. The arc-shaped reinforcing part 11 can enhance the connection strength between the positioning rod 10 and the material guide groove 3, improve the load-bearing capacity of the positioning rod 10, and the integral design of the arc-shaped reinforcing part 11 and the positioning rod 10 facilitates actual processing and molding, and can further enhance the overall structural stability.

[0029] The screw-lock structure includes a spiral guide groove 12, a spiral buckle 13, and a limiting buckle 14. The spiral guide groove 12 is located on the outer wall of the discharge port 18, the spiral buckle 13 is located on the inner wall of the discharge guide groove 13, and the limiting buckle 14 is located at the end of the spiral guide groove 12. When locking the powder bottle 1, the spiral buckle 13 rotates along the spiral guide groove 12. When the limiting buckle 14 engages with the spiral buckle 13, the powder bottle 1 is locked in place. The structure is cleverly and reasonably designed. The spiral guide groove 12 provides a clear guide path for the rotation of the powder bottle 1, ensuring that the powder bottle 1 accurately reaches the designated position and avoiding locking failure or inaccurate positioning of the wall-breaking needle 4 due to positional errors. When the limiting buckle 14 engages with the spiral buckle 13, a sound will be emitted to indicate that the rotation is in place. The engagement of the two can provide a stable locking force, ensuring that the powder bottle 1 will not loosen or fall off in the locked state, ensuring stability and reliability during operation. This design also facilitates actual operation and improves work efficiency. The screw-locking structure of this application preferably has two sets. The cross-sections of the two spiral guide grooves 12 are centrally symmetrically arranged along the center of the discharge port 18, and the cross-sections of the two spiral buckles 12 are centrally symmetrically arranged along the center of the discharge guide groove 3. Corresponding to the two sets of screw-locking mechanisms in this application, two wall-breaking needles 4 are also preferably provided. The two wall-breaking needles 4 are located at both ends of the positioning rod 10 and are centrally symmetrically arranged along the center of the discharge guide groove 3. With the screw-locking structure and the two sets of wall-breaking needles 4, the directional rotation angle α of the powder bottle 1 is limited to greater than 60° and less than 180°. That is, each wall-breaking needle 4 rotates synchronously by an angle α along the edge of the film. The angle size is cleverly and reasonably designed. By reasonably controlling the size of the rotation angle α, while ensuring the stability and reliability of locking, the wall-breaking needle 4 only makes a controllable opening at the edge of the film, avoiding excessive puncture and material loss of the film, realizing the gradual release of powder, and ensuring the stability and controllability of powder release. In actual design applications, the number of screw-on structures and the number of wall-breaking needles 4 can be adjusted according to requirements, and the value of the rotation angle α can be adjusted according to the design quantity, so that while the powder bottle 1 is tightened, the film will not be excessively punctured and powder will fall off, and the powder can be released gradually.

[0030] The spiral buckle 13 is provided with a groove 15. When the powder bottle 1 is screwed into place, the limiting buckle 14 is engaged in the groove 15. The groove 15 provides a clear engagement position for the limiting buckle 14. When the powder bottle 1 is locked in place, the limiting buckle 14 is precisely embedded in the groove 15, forming a stable engagement and improving the locking reliability. When the limiting buckle 14 is embedded in the groove 15, the operator can get clear feedback by hand, hear a sound and feel a change in resistance, and quickly confirm whether the powder bottle 1 has been rotated into place, reducing operational uncertainty and preventing the limiting buckle 14 from being not fully engaged or over-rotated. When disassembling, the operator only needs to apply reverse force to rotate the powder bottle 1 to make the limiting buckle 14 disengage from the groove 15, and then it can be completely disassembled.

[0031] The spiral guide groove 12 includes a spiral guide section 16 and a vertical guide section 17. The spiral guide section 16 is arranged along the outer wall of the discharge port 18. Both the terminating end and the starting end of the spiral guide section 16 are closed structures, and a limiting buckle 14 is provided at the terminating end. The vertical guide section 17 is located on the side of the starting end of the spiral guide section 16. One end of the vertical guide section 17 is connected to the spiral guide section 16, and the other end of the vertical guide section 17 is an open structure. The structure is compact and reasonable. When the discharge port 18 of the powder bottle 1 is vertically inserted into the discharge guide groove 3, the spiral buckle 13 passes through the corresponding vertical guide section 17 and enters the spiral guide groove. Within section 16, vertical guide section 17, in conjunction with spiral buckle 13, enables precise insertion and positioning of powder bottle 1 within material guide groove 3. Spiral buckle 13 enters spiral guide section 16 and rotates from the starting end to the ending end, engaging with limit buckle 14 at the ending end to ensure that powder bottle 1 is locked in place and securely locked. The spiral guide groove 12, with its closed structure at both ends, is designed with a specific path for powder bottle 1 to rotate, enabling directional and angled rotation of powder bottle 1. When locking, powder bottle 1 can only rotate from the starting end to the ending end, while when disassembling, powder bottle 1 can only rotate from the ending end to the starting end, with both angle and direction limited.

[0032] This utility model features a clever and reasonable structural design with strong practicality. The entire operation is completely enclosed, eliminating the risk of powder leakage and reducing environmental pollution. Furthermore, the use of a screw-lock structure ensures more accurate positioning, allowing the powder bottle 1 to rotate at a fixed angle. As the powder bottle 1 rotates into position and locks, the breaking needle 4 precisely punctures the membrane, releasing the powder while avoiding excessive puncture and fall of the membrane, thus improving practicality and operability. In actual operation, the powder bottle 1 is vertically inserted into the discharge guide groove 3. The spiral buckle 13 enters the corresponding spiral guide section 16 from the vertical inlet section 17. Then, it is rotated from the starting end to the ending end of the spiral guide section 16. A sound will be heard and resistance will be felt. At this time, the spiral buckle is engaged with the limit buckle 14, and the powder bottle 1 is rotated and locked in place. The film attached to the discharge port 18 of the powder bottle 1 is also precisely pierced by the wall-breaking needle 4. At this time, the film will not fall off, and the powder can also fall off. After the powder has completely fallen off, the powder bottle 1 is rotated in the opposite direction to disengage the spiral buckle from the limit buckle 14. Then, it is rotated from the ending end to the starting end of the spiral guide section 16 and the powder bottle 1 is lifted vertically to complete the disassembly operation.
