TECHNICAL FIELD

[0001] The utility model belongs to food printing equipment technical field, concretely relates to a food printer ink cartridge ink jet mouth protection assembly. BACKGROUND

[0002] The ink cartridge ink jet mouth of the existing food printer does not have a protection assembly, which leads to the following problems: 1) after printing is completed and the ink cartridge returns to the initial position, the ink remaining in the ink jet mouth will block the ink jet mouth, resulting in failure to print normally next time; 2) the ink jet mouth is exposed, and the ink near the ink jet mouth is prone to dry out. SUMMARY

[0003] The utility model discloses a food printer ink cartridge ink jet mouth protection assembly, which solves the above technical problems.

[0004] To solve the above technical problems, the utility model adopts the following scheme:

[0005] The food printer ink cartridge ink jet mouth protection assembly includes a scraping plate for removing ink remaining in the ink jet mouth of the ink cartridge and a moisturizing assembly for keeping the ink jet mouth of the ink cartridge moist after printing is completed.

[0006] In the present application, the scraping plate and the moisturizing assembly are provided to remove the ink remaining in the ink jet mouth and keep the ink jet mouth moist, thereby preventing the ink from drying out and blocking the ink jet mouth.

[0007] Further optimization is that the scraping plate is arranged at the initial position of the ink cartridge, and the upper end of the scraping plate is flush with the ink jet mouth position of the ink cartridge.

[0008] After printing is completed, the ink cartridge returns to the initial position along the set route, the scraping plate removes the ink remaining in the ink jet mouth of the ink cartridge, and the ink is prevented from solidifying and blocking the ink jet mouth.

[0009] Further optimization is that the moisturizing assembly includes an assembly body, a rotating shaft is arranged in the middle of the assembly body, one end of the rotating shaft is a pressure receiving part, and the other end is a protection part; the pressure receiving part is provided with an inclined surface, and the height of the inclined surface is arranged from low to high along the direction in which the ink cartridge returns to the initial position.

[0010] When the ink cartridge does not return to the initial position, the lower end of the inclined surface of the pressure receiving part is lower than the height corresponding to the lower end of the trigger, and the upper end of the inclined surface is higher than the height corresponding to the lower end of the trigger, at this time, the protection part is lower than the height corresponding to the lower surface of the ink cartridge.

[0011] When the ink cartridge returns to the initial position, the assembly body rotates a certain angle around the rotating shaft, at this time, the lower end of the trigger abuts on the pressure receiving part, the protection part covers the ink jet mouth of the ink cartridge, and is tightly attached to the lower surface of the ink cartridge; the trigger is the lower end of the ink cartridge, or a connecting block in relative fixed position relationship with the ink cartridge.

[0012] When the printing is completed and the ink cartridge returns to the initial position along the set route, the trigger member contacts the lower end of the inclined surface, and as the ink cartridge continues to move to the initial position, the trigger member moves along the inclined surface and presses the pressure-bearing part, in the process, the assembly body rotates around the rotating shaft, and the protection part is upwardly tilted, when the ink cartridge returns to the initial position, the protection part is in close contact with the lower surface of the ink cartridge, covering the ink ejection port, so that the ink ejection port is kept wet, preventing the ink in the residual ink ejection channel from drying and clogging the ink ejection port, thereby affecting the subsequent normal printing.

[0013] Further optimization, the protection part is made of silica gel material, and the whole is an open cavity structure, the shape of the cavity edge is matched with the lower end surface of the ink cartridge; the protection part is detachably connected with the assembly body.

[0014] When the ink cartridge returns to the initial position, the edge of the protection part is in close contact with the edge of the lower surface of the ink cartridge, and the ink ejection port is in the cavity of the protection part, preventing the ink ejection port from being directly pressed by the protection part. The silica gel material has a certain elasticity, so that it can better fit the lower surface of the ink cartridge.

[0015] The protection part is detachably connected with the assembly body, which is convenient for replacing the corresponding protection part according to the specifications of the ink cartridge, easy to operate and has strong adaptability.

[0016] Further optimization, one end of the assembly body for connecting the protection part is provided with a recess, and the bottom of the protection part is provided with a connecting column; the protection part is inserted into the recess through the connecting column, so that it is connected with the assembly body;

[0017] A through hole is formed in the connecting column, the through hole communicates the cavity of the protection part with the recess, and a channel is formed in the assembly body to communicate the recess with the external atmosphere.

[0018] By inserting the connecting column into the recess, the protection part is stably connected with the assembly body, and by forming the through hole and the channel, it is prevented that after the protection part is closely fitted with the lower surface of the ink cartridge, negative pressure is generated in the cavity of the protection part, so that the protection part cannot normally separate from the ink cartridge when the ink cartridge leaves the initial position next time.

[0019] The channel has a small diameter and is curved, so that more air flow enters the cavity of the protection part, preventing the ink cartridge from drying.

[0020] Further optimization, the base is detachably connected on the printer support, and the ink scraping plate and the moisturizing assembly are detachably arranged on the base.

[0021] Further optimization, the base is provided with a limiting groove for embedding the moisturizing assembly, and a groove is formed in the side wall of the limiting groove for clamping the rotating shaft of the assembly body.

[0022] The limiting groove is arranged to prevent the displacement of the moisturizing assembly, so that the protection part cannot cover the ink jet port.

[0023] Further optimization, the elastic member is arranged between the assembly body and the upper bottom surface of the base, and the elastic member is located on the side close to the pressure receiving part; when the ink cartridge returns to the initial position, the elastic member is in a compressed state.

[0024] During the ink cartridge returning process, the trigger member extrudes the pressure receiving part, and the elastic member is compressed. When the ink cartridge leaves the initial position, the moisturizing assembly is reset under the restoring force of the elastic member, so that the pressure receiving part is upturned, that is, the upper end of the inclined surface of the pressure receiving part is higher than the trigger member, so that the trigger member can extrude the pressure receiving part next time the ink cartridge returns.

[0025] Further optimization, the base is provided with a hinge limiting plate, the limiting plate is provided with a clamping member at the end away from the hinge point, and the base is provided with a first protrusion at the corresponding position; the limiting plate and the outer side surface of the base form a slot for inserting the ink scraping plate; when the limiting plate rotates around the hinge point by a certain angle, the protrusion is connected with the clamping member, and the limiting plate is in a locked state. At this time, the inner side surface of the limiting plate and the outer side surface of the base clamp and lock the ink scraping plate, preventing it from loosening or even falling off.

[0026] The limiting plate is hinged to the base, which is convenient for loosening and locking, and is beneficial to replacing the ink scraping plate, and the operation is convenient.

[0027] Further optimization, the inner side surface of the limiting plate and the outer side surface of the base are respectively provided with a plurality of second protrusions, and when the limiting plate is in the locked state, the plurality of second protrusions divide the slot into a plurality of ink scraping plate insertion positions.

[0028] Because the positions of the ink jet ports of ink cartridges of different specifications are different, the ink scraping plate needs to be arranged at the corresponding position. Therefore, the adaptability is higher.

[0029] Compared with the prior art, the utility model has the following beneficial effects:

[0030] 1、In the application, the ink scraping plate and the moisturizing assembly are arranged to remove the residual ink from the ink jet port, and keep the ink jet port in a moisturizing state, preventing the ink from drying and clogging the ink jet port.

[0031] 2、The protection part is made of silica gel and has a certain elasticity, so that it can better fit the lower surface of the ink cartridge. The protection part and the assembly body are detachably connected, which is convenient for replacing the corresponding protection part according to the specifications of the ink cartridge, and the operation is convenient and the adaptability is high.

[0032] 3. By inserting the connecting column into the concave cavity, the protective part is stably connected to the component body. By opening through holes and channels, it is prevented that the protective part is tightly fitted with the lower surface of the ink cartridge, which will cause negative pressure to be generated in the cavity of the protective part, resulting in the protective part being unable to detach from the ink cartridge normally when the ink cartridge leaves its initial position next time.

[0033] 4. By providing an elastic member, when the ink cartridge is returned to its original position, the trigger member presses against the pressure-bearing portion, compressing the elastic member. When the ink cartridge leaves its initial position, the restoring force of the elastic member resets the moisturizing assembly, causing the pressure-bearing portion to tilt upward. That is, the upper end of the inclined surface of the pressure-bearing portion is higher than the trigger member, ensuring that the trigger member can press against the pressure-bearing portion when the ink cartridge is returned to its original position.

The base 3 is detachably connected to the printer bracket, and both the ink scraper and moisturizing assembly are detachably mounted on the base.

[0041] In this embodiment, the base 3 is connected to the printer bracket via a plug connector 34 and bolts 35 at its bottom. Figure 2 shown.

[0042] The ink scraping plate and the moisturizing assembly are arranged in the application to remove the residual ink from the ink ejection port and keep the ink ejection port moist to prevent the ink from drying and blocking the ink ejection port.

[0043] In the embodiment, the ink scraping plate 1 is arranged at the initial position of the ink cartridge, and the upper end of the ink scraping plate 1 is flush with the position of the ink ejection port of the ink cartridge.

[0044] After printing, the ink cartridge returns to the initial position along the set route, the ink scraping plate removes the residual ink from the ink ejection port of the ink cartridge, and prevents the ink from solidifying and blocking the ink ejection port.

[0045] In the embodiment, as shown in Figure 3 The moisturizing assembly 2 includes an assembly body 21, the middle of the assembly body 21 is provided with a rotating shaft 214, one end of the assembly body 21 is a pressure receiving part 211, and the other end is a protection part 212; wherein the pressure receiving part 211 is provided with an inclined surface 2111, and the inclined surface 2111 is arranged from low to high along the direction in which the ink cartridge returns to the initial position.

[0046] When the ink cartridge does not return to the initial position, the lower end of the inclined surface of the pressure receiving part is lower than the height corresponding to the lower end of the trigger, the upper end of the inclined surface is higher than the height corresponding to the lower end of the trigger, and at this time, the protection part is lower than the height corresponding to the lower surface of the ink cartridge; when the ink cartridge returns to the initial position, the assembly body rotates around the rotating shaft by a certain angle, at this time, the lower end of the trigger abuts against the pressure receiving part, and the protection part covers the ink ejection port of the ink cartridge and is tightly attached to the lower surface of the ink cartridge.

[0047] In the embodiment, the trigger is the lower end of the ink cartridge. In other embodiments, the trigger can be a connecting block in a relatively fixed position relationship with the ink cartridge.

[0048] When the ink cartridge returns to the initial position along the set route after printing, the trigger contacts the lower end of the inclined surface, and as the ink cartridge continues to move to the initial position, the trigger moves along the inclined surface and presses the pressure receiving part, in the process, the assembly body rotates around the rotating shaft, and the protection part is raised upward, when the ink cartridge returns to the initial position, the protection part is tightly attached to the lower surface of the ink cartridge and covers the ink ejection port, so that the ink ejection port is kept moist, and the residual ink in the ink ejection channel is prevented from drying and blocking the ink ejection port, thereby affecting the subsequent normal printing.

[0049] In the embodiment, as shown in Figure 5 The base 2 is provided with a limiting groove 32 for embedding the moisturizing assembly, and two groups of grooves 321 for clamping the rotating shaft of the assembly body are arranged on the side wall of the limiting groove 32. The assembly body corresponding to different ink cartridge specifications is different, and the position of the rotating shaft is different, therefore, a plurality of groups of grooves are arranged to satisfy the assembly body corresponding to different ink cartridges, and the adaptability is strong.

[0050] In this embodiment, the protective portion 212 is made of silicone material and has an open cavity structure as a whole. The shape of the cavity edge is adapted to the lower end surface of the ink cartridge; the protective portion is detachably connected to the component body.

[0051] When the ink cartridge returns to its initial position, the edge of the protective part aligns with the edge of the ink cartridge's bottom surface, and the ink jet nozzle is located within the protective part's cavity, preventing the nozzle from being directly squeezed by the protective part. The silicone material has a certain degree of elasticity, allowing it to better fit the bottom surface of the ink cartridge.

[0052] The protective part is detachably connected to the component body, so that the corresponding protective part can be replaced according to the specifications of the ink cartridge, and the operation is convenient and the adaptability is strong.

[0053] In this implementation, if Figure 3 、 4 As shown, a cavity 2121 is provided at one end of the component body 21 for connecting the protective part, and a connecting column 2131 is provided at the bottom of the protective part 212; the protective part is inserted into the cavity through the connecting column to connect it to the component body; a through hole is provided in the connecting column, which connects the cavity of the protective part with the cavity, and a channel 2122 is provided on the component body to connect the cavity with the external atmosphere.

[0054] By inserting the connecting column into the concave cavity, the protective part is stably connected to the component body. By providing through holes and channels, it is prevented that the protective part is tightly fitted to the lower surface of the ink cartridge, which would cause negative pressure to be generated in the cavity of the protective part, resulting in the protective part being unable to detach normally from the ink cartridge when the ink cartridge leaves its initial position next time it is printed.

[0055] The aperture of the channel is small and the channel is curved, which reduces the flow of air into the cavity of the protective part, thereby preventing the inkjet cartridge from drying out.

[0056] The limiting groove is provided to prevent the moisturizing component from shifting, so that the protective part cannot cover the inkjet port.

[0057] In this embodiment, an elastic member is provided between the component body 21 and the upper bottom surface of the base, and the elastic member is located on the side close to the pressure-bearing portion; when the ink cartridge returns to the initial position, the elastic member is in a compressed state.

[0058] In this embodiment, the elastic member is a spring, and limit posts 33 are respectively provided at corresponding positions on the bottom surface of the component body and the bottom surface of the base 3. The upper and lower ends of the spring are respectively sleeved on the corresponding limit posts to prevent the spring from being out of position.

[0059] During the ink cartridge's return, the trigger member presses against the pressure-bearing portion, compressing the elastic member. When the ink cartridge leaves its initial position, the restoring force of the elastic member resets the moisturizing assembly, causing the pressure-bearing portion to tilt upward. This means the upper end of the inclined surface of the pressure-bearing portion is higher than the trigger member, ensuring that the trigger member can press against the pressure-bearing portion the next time the ink cartridge is returned to its original position.

[0060] In the embodiment, the base 3 is provided with a hinge limiting plate 31, and a bayonet 312 is arranged at the end of the limiting plate 31 away from the hinge point, and a first protrusion 311 is arranged at the corresponding position of the base.

[0061] The inner side of the limiting plate and the outer side of the base form a clamping groove for the ink scraping plate.

[0062] When the limiting plate rotates around the hinge point by a certain angle, the first protrusion is connected with the bayonet, and the limiting plate is in the locked state. At this time, the inner side of the limiting plate and the outer side of the base clamp and lock the ink scraping plate, preventing it from loosening or even falling off.

[0063] The limiting plate is hinged to the base, which is convenient for loosening and locking, and is beneficial to replace the ink scraping plate and is convenient to operate.

[0064] In the embodiment, as shown in the figure, Figure 5 The inner side of the limiting plate 31 and the outer side of the base 3 are respectively provided with a plurality of second protrusions 313, and when the limiting plate is in the locked state, the plurality of second protrusions divide the clamping groove into a plurality of ink scraping plate insertion positions.

[0065] Because the positions of the ink ejection ports of ink cartridges of different specifications are different, the ink scraping plate needs to be arranged at the corresponding position. Therefore, such arrangement is more adaptable.

[0066] Based on the above ideal embodiment of the present application, through the above description, relevant personnel can make various changes and modifications without deviating from the technical idea of the present application. The technical scope of the present application is not limited to the contents of the specification, and the technical scope must be determined according to the scope of the claims.
