Description

TECHNICAL FIELD

[0001] The utility model relates to additive manufacturing technology field, concretely is a kind of consumable disc spring rotary shaft. BACKGROUND

[0002] At present, in the automatic production equipment, the installation and use of consumable disc are very common. In the prior art, the consumable disc is usually fixed and installed by simple bearing structure, i.e. the consumable disc is fixed on the machine table by the center bearing, and the stable rotation of the consumable disc is realized by friction. At the same time, some improved consumable disc fixing devices adopt threaded fastening or buckle type structure to improve the installation stability of the consumable disc. In addition, some devices adopt fixed-size clamping mechanisms, but such structure can only be applied to consumable discs of specific specifications.

[0003] However, the consumable disc fixing structure in the prior art has many deficiencies: first, in the process of continuous feeding, the consumable disc can only rotate in one direction for feeding, and cannot be tightened in reverse. When the consumable disc vibrates or changes speed during rotation, it is easy to cause the consumable to relax, causing the consumable to wind or even break. Second, the traditional fixing method often needs to use tools for installation and disassembly, which is complicated and reduces production efficiency. Third, the existing fixing structure generally lacks universality and cannot adapt to consumable discs of different specifications, resulting in the need for enterprises to provide different fixing devices for consumable discs of different specifications, increasing equipment costs and storage space. In addition, the current mainstream method of installing the consumable disc is to install it directly on the center shaft. This installation method has many stability problems: on the one hand, the consumable disc and the center shaft only rely on simple cooperation to maintain coaxiality, which can easily cause eccentricity and shaking during long-term use, resulting in unstable rotation of the consumable disc. On the other hand, when the weight of the consumable disc is large or the rotation speed is high, the simple axial fixing structure is easy to loosen, which not only affects the normal supply of consumables, but also may cause safety hazards to the equipment. At the same time, some improved devices that use fixed-size clamping mechanisms, although they improve the stability of the consumable disc to some extent, lack the function of elastic adjustment and are easy to damage the consumable disc due to improper clamping force, and cannot meet the assembly requirements of consumable discs of different specifications. These problems not only reduce the efficiency of the equipment in actual production, but also increase the difficulty of equipment maintenance and consumable replacement.

[0004] Therefore, a new type of consumable disc spring rotary shaft is needed to solve the problems of insufficient tension control, inconvenient installation and disassembly, poor adaptability and short service life in the prior art. The device should have an intelligent tension adjustment function to automatically tighten the consumables through a reverse rotation mechanism. At the same time, an innovative elastic clamping structure needs to be designed to achieve quick installation and disassembly, and to adapt to consumable discs of different specifications, improving the universality and practicality of the equipment.

[0066] Please refer to Figures 1-5 The present application provides a technical scheme: a consumable disc spring rotary shaft, comprising:

[0067] The outer cylinder 1 is provided with a plurality of groups of connecting grooves 11 in a regular annular array on the surface thereof;

[0068] The first annular limiting piece 2 is fixedly connected to one side of the outer cylinder 1;

[0069] A plurality of groups of elastic clamping jaw mechanisms 3 are connected to the plurality of groups of connecting grooves 11, respectively.

[0070] Specifically, the diameter length of the first annular limiting piece 2 is greater than the inner diameter length of the consumable disc, so that the first annular limiting piece 2 plays a limiting role on the outer cylinder 1, avoiding the complete penetration of the outer cylinder 1 from the inner side of the consumable disc to cause disengagement.

[0071] Specifically, the connecting grooves 11 on the surface of the outer cylinder 1 provide a firm mounting basis for the elastic clamping jaw mechanism 3, ensuring the stability of clamping.

[0072] Referring to the drawings Figures 1-5 , the elastic clamping jaw mechanism 3 comprises:

[0073] A first elastic part 31 is fixedly connected in the connecting groove 11;

[0074] A second elastic part 32 is integrally connected with the first elastic part 31;

[0075] A third elastic part 33 is integrally connected with the second elastic part 32;

[0076] A consumable disc positioning block 34 is integrally connected at the intersection of the third elastic part 33 and the second elastic part 32;

[0077] An insertion part 35 is integrally connected on the side of the third elastic part 33 away from the consumable disc positioning block 34;

[0078] Among them,

[0079] When no external force is applied, the included angle between the first elastic part 31 and the second elastic part 32 is greater than the included angle between the second elastic part 32 and the third elastic part 33;

[0080] When external force is applied, the second elastic part 32 and the third elastic part 33 sequentially move towards the side of the connecting groove 11 through deformation.

[0081] Specifically, the elastic clamping jaw mechanism 3 is made of plastic material and has a certain deformability. When the outer cylinder 1 is inserted into the inside of the consumable disc, first, the insertion part 35 on the elastic clamping jaw mechanism 3 faces forward, playing a guiding role and facilitating insertion into the inside of the consumable disc. With the continued insertion of the outer cylinder 1, the inner wall of the center hole of the consumable disc will exert radial pressure on the elastic clamping jaw mechanism 3. At this time, the third elastic part 33 and the second elastic part 32 in the elastic clamping jaw mechanism 3 will sequentially deform and move towards the side of the connecting groove 11. When the center hole of the consumable disc is completely matched with the elastic clamping jaw mechanism 3, the consumable disc positioning block 34 will form stable supporting contact with the outer disc surface of the consumable disc, providing radial positioning for the consumable disc. At this time, the elastic clamping jaw mechanism 3 is in a compressed state, and the restoring force generated by its elastic deformation forms a stable clamping force with the inner wall of the center hole of the consumable disc, ensuring that the consumable disc rotates coaxially with the outer cylinder 1. When disassembling, the outer cylinder 1 only needs to be pulled out of the center hole of the consumable disc, and the elastic clamping jaw mechanism 3 will automatically return to the original state, the whole process is simple and fast, and does not require any tool assistance.

[0082] Referring to the drawings Figure 17 , the elastic clamping jaw mechanism 3 comprises:

[0083] Specifically, the guiding effect of the insertion part 35 and the progressive deformation characteristics of the elastic jaw mechanism 3 make the installation process smoother, and the setting of the consumable disc positioning block 34 ensures the accurate positioning of the consumable disc.

[0084] Specifically, the present application realizes the rapid installation and disassembly of the consumable disc by setting the elastic jaw mechanism 3. The elastic jaw mechanism 3 adopts an innovative multi-section elastic structure design, which allows the jaw to produce a preset deformation according to external force, thereby self-adapting to consumable discs of different specifications, ensuring uniform distribution of clamping force, sufficient clamping strength, and avoiding damage to the consumable disc.

[0085] Specifically, the elastic jaw mechanism 3 of the present application realizes multi-point uniform clamping of the consumable disc through a regular ring array arrangement, which not only improves the stability of the installation, but also facilitates the quick insertion and extraction of the jaw through the design of the insertion part 35, greatly improving the operational convenience of the device. Embodiment 2

[0086] The same parts as described in Embodiment 1 are not repeated here.

[0087] Please refer to Figures 6-11 The utility model provides a technical scheme: a consumable disc spring rotary shaft, comprising:

[0088] The outer cylinder 1 has a regular ring array of connection grooves 11 on its surface;

[0089] A plurality of elastic jaw mechanisms 3 are connected to the plurality of connection grooves 11, respectively;

[0090] The inner cylinder 4 is movably connected to the inner side of the outer cylinder 1, and one end of the inner cylinder 4 is fixedly connected to an end shaft 41, and the other end of the inner cylinder 4 is fixedly connected to two groups of lock blocks 42;

[0091] The rotary mechanism 5 is connected to the outer cylinder 1 and the end shaft 41;

[0092] The second ring-shaped limiting piece 6 is connected to the side of the outer cylinder 1 away from the end shaft 41.

[0093] Specifically, the end of the inner cylinder 4 close to the end shaft 41 is a closed structure, and the end of the inner cylinder 4 close to the lock block 42 is an open structure suitable for installation.

[0094] Referring to the drawings attached Figures 6-9 The elastic jaw mechanism 3 comprises:

[0095] The first elastic part 31 is fixedly connected in the connection groove 11;

[0096] The second elastic part 32 is integrally connected with the first elastic part 31.

[0097] The third elastic part 33 is integrally connected with the second elastic part 32.

[0098] The consumable disc positioning block 34 is integrally connected at the joint of the third elastic part 33 and the second elastic part 32.

[0099] The insertion part 35 is integrally connected to the side of the third elastic part 33 away from the consumable disc positioning block 34.

[0100] Wherein,

[0101] When no external force is applied, the included angle between the first elastic part 31 and the second elastic part 32 is greater than the included angle between the second elastic part 32 and the third elastic part 33.

[0102] When an external force is applied, the second elastic part 32 and the third elastic part 33 move towards the side of the connecting groove 11 in sequence through deformation.

[0103] The accompanying drawings are referred to in the description of the specification. Figure 7 Figures 11-14 The rotating mechanism 5 comprises:

[0104] The first auxiliary ring 51 is fixed to the outer surface of the outer cylinder 1.

[0105] The second auxiliary ring 52 is fixed to the side of the first auxiliary ring 51 close to the end shaft 41.

[0106] The spring 53 is fixed at one end to the end shaft 41 and at the other end to the second auxiliary ring 52.

[0107] The end cover 54 is connected to the second auxiliary ring 52, and the spring 53 is connected to the inner side of the end cover 54.

[0108] Specifically, the end cover 54 has a protective effect on the spring 53, and the structural design of the rotating mechanism 5 enables the spring 53 to store elastic potential energy when the consumable disc rotates forward and release energy to drive the consumable disc to rotate reversely at the appropriate time, thereby realizing the automatic tightening function of the consumables. The cooperative design of the first auxiliary ring 51 and the second auxiliary ring 52 ensures that the working state of the spring 53 is always within the optimal range, not only improving the stability of the rotating process, but also significantly prolonging the service life of the spring, providing reliable guarantee for the long-term stable operation of the device.

[0109] ​​​​​​​​​​​​​​​​​​​​​​​​​​​​Specifically, the outer cylinder 1, the elastic clamping jaw mechanism 3, the first auxiliary ring 51 and the second auxiliary ring 52 are fixedly connected, and the inner cylinder 4 and the end shaft 41 are fixedly connected. Since the end shaft 41 and the second auxiliary ring 52 are connected through the spring 53, the outer cylinder 1 and the inner cylinder 4 are elastically connected through the spring 53. In normal use, when the elastic clamping jaw mechanism 3 is inserted into the inside of the consumable disc, the elastic clamping jaw mechanism 3 forms a stable connection with the consumable disc, and the outer cylinder 1, the elastic clamping jaw mechanism 3 and the consumable disc rotate synchronously. The inner cylinder 4 can be fixedly installed on the fixed shaft of the printer supply device. When the consumable disc rotates to drive the outer cylinder 1 to rotate, the inner cylinder 4 remains fixed, the spring 53 is gradually twisted, and the elastic potential energy is stored. When the consumable disc rotates by a certain angle, the elastic potential energy stored in the spring 53 drives the inner cylinder 4 to rotate reversely, thereby driving the consumable disc to rotate reversely by a proper angle, realizing the tightening of the consumable, and effectively solving the problems of slack and winding of the consumable in the prior art, and significantly improving the reliability and working efficiency of the equipment. Through the elastic connection relationship between the inner cylinder 4 and the outer cylinder 1, automatic tension control of the consumable is realized, which provides reliable guarantee for continuous and stable operation of the equipment.

[0110] Specifically, the application adopts an innovative rotary mechanism 5 design, which ingeniously solves the problems of slack and winding of the consumable. When the consumable disc rotates by a certain angle, the elastic potential energy stored in the spring 53 drives the consumable disc to reversely rotate by a proper angle, thereby realizing the automatic tightening of the consumable. This design of forward and reverse rotation cooperation can always keep the consumable in a proper tension state, effectively preventing the slack and winding of the consumable.

[0111] Referring to the drawings attached to the specification Figures 11-12 The outer surface of the second auxiliary ring 52 is provided with two groups of first arc-shaped grooves 521, the middle part of the outer surface of the second auxiliary ring 52 is provided with two groups of second arc-shaped grooves 522, the second arc-shaped grooves 522 are provided with a clamping groove 523 at one end away from the first arc-shaped grooves 521, the two groups of second arc-shaped grooves 522 are respectively connected with the two groups of first arc-shaped grooves 521, the end cover 54 is provided with two groups of inner grooves 541, the inner grooves 541 are integrally connected with elastic blocks 542 on the inner wall, the elastic blocks 542 are integrally connected with protruding blocks 543, the protruding blocks 543 are connected in the first arc-shaped grooves 521 and the second arc-shaped grooves 522 by rotation in turn, and then the protruding blocks 543 are connected in the clamping grooves 523 by rotation.

[0112] Specifically, the outer diameter length of the second auxiliary ring 52 is adapted to the inner diameter length of the end cover 54, and the elastic blocks 542 are made of plastic material with deformation ability.

[0113] Referring to the drawings attached to the specification Figure 18 It is a schematic view of the embodiment inserted into the consumable disc.

[0114] Specifically, in use, the end cover 54 is first connected to the outer side of the second auxiliary ring 52, so that the two sets of protrusions 543 are respectively connected in the two sets of first arc-shaped grooves 521, and then the two sets of protrusions 543 are rotated into the two sets of second arc-shaped grooves 522 by rotating the end cover 54. Since the protrusions 543 are located on the inner side of the end cover 54 without external force, the elastic blocks 542 are always in an outwardly deformed state when the protrusions 543 are in contact with the inner walls of the first arc-shaped grooves 521 and the second arc-shaped grooves 522. When the end cover 54 continues to rotate, the two sets of protrusions 543 move to the positions of the two sets of clamping grooves 523, and under the action of the elastic blocks 542, the protrusions 543 are automatically reset to the initial position of the end cover 54, that is, the protrusions 543 are clamped into the clamping grooves 523, forming a stable locking state. This locking mechanism has good self-locking function, because the protrusions 543 need to overcome the elastic force of the elastic blocks 542 to separate from the clamping grooves 523, thereby ensuring that the end cover 54 will not rotate and fall accidentally during normal operation.

[0115] Specifically, when the end cover 54 needs to be disassembled, a sufficient torsional force must be applied to make the protrusions 543 overcome the elastic deformation force of the elastic blocks 542 and separate from the clamping grooves 523. This design not only ensures the stability of the end cover 54 during normal operation, but also ensures that the end cover 54 can only be disassembled when a sufficient artificial torsional force is applied, effectively preventing accidental loosening of the end cover 54.

[0116] Referring to the drawings attached to the specification Figure 6 The inner wall of the second annular limiting piece 6 is spaced apart to provide two sets of insertion grooves 61, the lock blocks 42 are adapted in shape to the insertion grooves 61, and the second annular limiting piece 6 is fixedly connected to two sets of arc-shaped slopes 62 away from the outer cylinder body 1.

[0117] Specifically, through the cooperation of the insertion grooves 61 and the lock blocks 42, the second annular limiting piece 6 can pass through the two sets of lock blocks 42, so that the second annular limiting piece 6 is abutted against the end faces of the outer cylinder body 1 and the inner cylinder body 4, and the second annular limiting piece 6 can have the same effect as the first annular limiting piece 2, having a limiting effect when the outer cylinder body 1 is inserted into the consumable wire disc.

[0118] Referring to the drawings attached to the specification Figures 15-16 The heights of the arc-shaped slopes 62 increase in turn, the lock blocks 42 pass through the insertion grooves 61, and then the lock blocks 42 are abutted against the sides of the arc-shaped slopes 62 away from the second annular limiting piece 6 by rotating.

[0119] Specifically, the lower side of the arc-shaped slope 62, that is, the starting point, is connected with the slot 61, so that the lock block 42 is initially separated from the arc-shaped slope 62 after passing through the slot 61, and then gradually contacts with the two groups of arc-shaped slopes 62 by rotating the second annular limiting sheet 6, until the lock block 42 and the arc-shaped slope 62 form a stable abutment. This progressive locking mode not only is simple to operate, but also provides reliable self-locking function, ensuring the stability and safety of the consumable disc during high-speed operation, and providing a strong guarantee for the safe operation of the equipment.

[0120] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
