Description

Technical Field

[0001] The present invention relates to the technical field of 3D printing, and in particular to a 3D printing ink cartridge. Background Art

[0002] At present, if a 3D printer wants to print products of different colors or products with multiple colors interlaced and overlapped within the same product, it is necessary to prepare various colors of wire consumables. When printing, the wires of different colors are replaced as needed to produce colorful products that meet the needs. This processing form that uses the inherent color of the consumables to select raw materials is not only cumbersome to replace the wires and has low work efficiency, but also has limited application due to the small variety of consumable colors. In addition, in the actual production process, due to color issues, the amount of goods that need to be reserved is relatively large. For example, if a company has 500 rolls of each color in stock, if 7 colors are needed, 3,500 rolls will be needed, resulting in an exponential increase in the number of stocks, which can easily lead to problems of material accumulation or shortage at the stocking place.

[0003] To this end, China Patent Announcement No. CN105109047B discloses a 3D printing ink cartridge, including an ink cartridge body and a side cover, the cavity of the ink cartridge body is used to accommodate dye powder and porous material, and wire holes are opened at corresponding positions of the top plate and the bottom plate of the ink cartridge body. The porous material is wrapped around the wire hole so that the porous material wraps the wire passing through the inner cavity of the ink cartridge when it forms contact, and the ink cartridge cavity outside the porous material is used to accommodate dye powder. This patent can solve the problem of product color restrictions and large stock quantity due to the color type restrictions of printing consumables. However, the above scheme has the following problems: 1. In the above scheme, dye powder is placed in the porous material, and then the primary color wire passes through the porous material, and the primary color wire is rubbed with the porous material, so as to dye the outer surface of the primary color wire, but the dye powder is only applied to the outer surface of the primary color wire, which is easy to fall off during the transmission process, and the dyeing effect is not good. 2. The above scheme is to place dye powder in a porous material, then pass the primary color wire through the porous material, and rub the primary color wire with the porous material, so as to dye the outer surface of the primary color wire. In this way, different sections of the primary color material are dyed with different colors. It is necessary to clean the dye powder in the porous material and then mix the dye powder of the required color. Since the pore size of the porous material is relatively small, it is easy for the dye to remain and color mixing is easy to occur. Summary of the invention

[0004] The present invention aims to provide a 3D printing ink cartridge, which can perform perforation dyeing on primary color wires to prevent the dye powder from separating from the primary color wires and improve the dyeing effect; at the same time, an independent inkjet structure is adopted so that the inkjet will not cause color mixing.

[0005] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a 3D printing ink cartridge, comprising an ink cartridge body, both sides of the ink cartridge body are provided with coaxial wire holes in the horizontal direction, the side wall of the ink cartridge body is provided with a guide plate, the guide plate and the wire hole are in the same horizontal plane, a guide frame is horizontally arranged in the ink cartridge body for point contact with the primary color wire, a punching mechanism for drilling blind holes for the primary color wire is vertically arranged on the guide plate, a linkage mechanism and a nozzle are arranged on the upper end surface of the ink cartridge body, the cross-sectional shape of the linkage mechanism is circular, the linkage mechanism includes an active cavity and a fixed cavity from top to bottom, the active cavity and the fixed cavity are connected by a support plate, a feeding mechanism is arranged in the fixed cavity, the feeding mechanism is connected to the nozzle, a plurality of partitions are vertically arranged in the active cavity, the active cavity is divided into a plurality of control cavities for controlling different dye powders by the partition, first limit blocks are connected to both sides of the lower end of the partition, a first gap is arranged between the first limit block and the support plate, and a slide plate is arranged in each control cavity in the horizontal direction, The slide plate slides up and down along the side wall of the control chamber, and the slide plate is located above the first limit block. The slide plate divides the control chamber into an upper chamber and a lower chamber. A first push rod is vertically arranged in the upper chamber, and the upper end of the first push rod extends out of the upper chamber. A fixed sleeve is sleeved on the upper end of the first push rod, and the first push rod is slidably connected to the fixed sleeve. The upper end surface of the fixed sleeve is connected to a rod cap, and the lower end of the first push rod is fixedly connected to a wedge-shaped spring block, and the lower end of the wedge-shaped spring block is fixedly connected to the upper end surface of the slide plate. A locking mechanism is arranged in the upper chamber; the lower chamber is filled with liquid, and the lower end surface of the slide plate is connected to the upper end surface of the support plate through a first spring, and the lower end of the slide plate is vertically connected to a first protrusion, and the lower end of the first protrusion extends into the first spring, and the upper end surface of the support plate is vertically connected to a trigger switch for controlling the feeding mechanism, and the upper end of the trigger switch extends into the first spring, and a second gap is arranged between the first protrusion and the trigger switch.

[0006] The principle of this scheme is: in actual application, first open the punching mechanism, place the primary color wire in the guide plate, push the primary color wire toward the direction of the ink cartridge body through the feeding mechanism of the 3D printer, push the primary color wire to the printing mechanism, and the printing mechanism punches blind holes on the upper end surface of the primary color wire. After printing is completed, manually press the rod cap of the dye powder of the required color downward by hand, and the fixed sleeve fixedly connected under the rod cap pushes the push rod to move downward, and the push rod pushes the wedge-shaped block to compress and deform. The wedge-shaped block will push the slide plate to move downward along the inner wall of the active cavity, so that the space of the lower cavity becomes smaller, and the liquid in the lower cavity will flow along the first gap to other connected active cavities, so that the liquid in other active cavities increases, and the slide plates in other active cavities move upward under the action of the liquid. At this time, the first spring is compressed and deformed, and the distance of the first gap becomes smaller, until the lower end of the first protrusion abuts against the upper end of the trigger switch, and then the push rod is locked by the locking mechanism in the upper cavity, so that the position of the slide plate is fixed. In this way, the feeding mechanism controlled by the trigger switch is turned on, and the feeding mechanism supplies the corresponding color of dye powder to the nozzle connected thereto, and the dye powder of the required color is sprayed in the blind hole of the primary color wire. After the primary color wire of the color is sprayed, the rod cap is pressed downward by hand, and the fixed sleeve fixedly connected to the rod cap moves downward, and the fixed sleeve pushes the push rod to move downward, and the push rod pushes the wedge-shaped block to continue to be squeezed and deformed, and then the rod cap is manually released, and the wedge-shaped block rebounds upward, generating a certain torque, so that the push rod deflects a certain angle relative to the fixed sleeve, so that the push rod moves upward after being unlocked. At this time, the push rod drives the slide plate to move upward, the first spring returns to its original position, the first protrusion separates from the trigger switch, and the feeding mechanism stops working. At the same time, the space in the lower cavity becomes larger. Since the active cavity is connected to other active cavities, the liquid flows back to the lower cavity of the active cavity through the first gap, and the slide plates in other active cavities return to their original positions.

[0007] Beneficial effects:

[0008] 1. In the present invention, a blind hole is punched on the upper surface of the primary color wire by a punching mechanism, and then the required dye powder is sprayed on the primary color wire by a nozzle, wherein a part of the dye powder will enter the blind hole, and the other part of the dye powder will stick to the surface of the primary color wire, and then it will be transmitted to the melting section of the 3D printer, and the dye powder and the primary color wire will be melted into a liquid state, so that the primary color wire is dyed into the required color. By punching blind holes on the primary color wire, more dye powder can be applied to the primary color wire to prevent the dye powder from falling off during the transmission process, thereby improving the dyeing effect.

[0009] 2. In the present invention, a guide plate is horizontally arranged on the side wall of the ink cartridge body close to the feeding direction, so that when the primary color wire is punched, the guide plate can provide a certain support to the primary color wire to prevent the primary color wire from deforming during the punching process. At the same time, a guide frame is horizontally arranged in the ink cartridge body to contact the primary color wire at a point, so that when the primary color wire is sprayed with dye powder, most of the dye powder will be sprayed in the blind hole and on the surface of the primary color wire, but a part of the dye powder will flow along the guide frame to the bottom of the ink cartridge body, and no dye powder will remain on the guide frame, so that it will not affect the primary color wire sprayed with dye powder later, and avoid color mixing.

[0010] 3. In the present invention, different colors are placed in different feeding mechanisms, and then the rod cap of the required color in the linkage mechanism is pressed, so that the liquid in the active cavity flows to other active cavities, so that the first protrusion is abutted against the trigger switch, thereby spraying the dye powder of this color on the primary color wire, and the feeding mechanisms of other colors will not be turned on, so that the feeding mechanisms work independently of each other, and the inkjet pipeline of each color is independent, and there will be no color mixing.

[0011] 4. In the present invention, the first push rod is slidably connected to the fixed sleeve, and a wedge-shaped block is provided at the lower end of the first push rod. When the first push rod is pressed downward, the wedge-shaped block is compressed and deformed, and the first push rod is locked by the locking mechanism. When it is necessary to unlock it, since the wedge-shaped block still has some deformation margin, the first push rod is pressed downward continuously, and the wedge-shaped block is compressed and deformed to the limit value of its compression deformation, and then the pressing force on the first push rod is removed, and the wedge-shaped block will have an upward rebound force, and since the upper surface of the wedge-shaped block is inclined, the wedge-shaped block will push the first push rod fixedly connected thereto to have a certain torsional force, thereby unlocking the first push rod. Through such a structural setting, it is more convenient to switch between the locking and unlocking states of the first push rod, thereby automatically controlling the opening and closing of the feeding mechanism.

[0012] Preferably, the feeding mechanism includes an air pump, a storage box and a discharge box, the air pump is fixedly connected in the fixed cavity, the storage box and the discharge box are both fixedly connected to the bottom of the fixed cavity, the air pump is connected to the upper end surface of the discharge box through a first air pipe, the bottom of the storage box is connected to the discharge box through a first pipe, a push plate is slidably connected along the side wall of the discharge box, the upper end surface of the push plate is connected to the upper end surface of the discharge box through a third spring, the upper end surface of the push plate is vertically connected to a pull rod, the lower end of the discharge box is connected to the second pipe and the discharge pipe in sequence, the discharge pipe is inclined, a baffle is vertically slidably connected to the discharge pipe, and the lower end of the baffle is connected to the end of the pull rod.

[0013] The dye powder in the storage box flows into the discharge box along the first pipe under the action of its own gravity. When the first protrusion contacts the trigger switch, the air pump is turned on, and the rotor in the air pump rotates forward, sucking the outside air into the upper part of the discharge box through the first air pipe. As the gas increases, the gas pushes the push plate downward, the third spring is stretched and deformed, and the push plate pushes the dye powder in the discharge box downward. The dye powder enters the discharge pipe along the second pipe. As the push plate moves downward, the pull rod fixedly connected to the push plate also moves downward, so that the pull rod pulls the baffle downward, the discharge pipe opens, and the dye powder enters the nozzle along the discharge pipe, thereby spraying on the blind hole and surface of the primary color wire. When the spraying process is completed, the first protrusion is separated from the trigger switch, and the air pump stops working, so that the third spring returns to its original position, the third spring drives the push plate to return to its original position, the push plate drives the pull rod to move upward, and the pull rod drives the baffle to move upward, so that the discharge pipe is blocked, and the dye powder in the storage box replenishes the discharge box under the action of its own gravity. Through such a feeding mechanism, the dye powder can be pushed and replenished in time, making the dye sprayed on the primary color wire more uniform.

[0014] Preferably, the locking mechanism includes a second spring, which is horizontally fixedly connected to both sides of the upper cavity, and a ball is fixedly connected to one end of the second spring close to the first push rod, and second protrusions are horizontally fixedly connected to both sides of the upper cavity, and the free ends of the second protrusions extend into the second springs, and grooves that can cooperate with the ball are provided on both sides of the first push rod. When people press the rod cap downward by hand, the first push rod moves downward and squeezes the wedge-shaped elastic block to compress and deform, and the second spring pushes the ball to embed into the groove. At this time, the first protrusion abuts against the trigger switch, thereby locking the first push rod. By setting up the locking mechanism, the first push rod can be locked while controlling the opening of the feeding mechanism to prevent the first push rod from moving upward, and the locking is relatively timely.

[0015] Preferably, a fixing plate is provided in the ink cartridge body, the fixing plate is located below the nozzle, the fixing plate is tilted downward, an opening is provided on one side of the ink cartridge body located at the lower end of the fixing plate, and an open collection box is fixedly connected to the opening. In this way, when the primary color wire is sprayed with dye, excess dye powder will fall onto the fixing plate, and under the action of its own gravity, the dye powder will fall into the collection box, or people can open the ink cartridge body regularly and sweep the dye powder on the fixing plate into the collection box, so as to facilitate the collection and cleaning of the above dye powder.

[0016] Preferably, the cross-section of the guide plate is U-shaped, and a plurality of chip removal holes are provided at the bottom of the guide plate, so as to guide the primary color wires to a certain extent, and at the same time, the waste chips after punching can be discharged along the chip removal holes, so as to avoid the waste chips affecting the transmission of the subsequent primary color wires.

[0017] Preferably, the plurality of nozzles are connected to each other via a connecting plate, and the connecting plate is in an arc shape, so that the nozzles can be reinforced and the stability of the structure can be increased. BRIEF DESCRIPTION OF THE DRAWINGS
