Abstract
Description
A floating buffer type high-speed inkjet printer Technical Field
[0001] The embodiments disclosed herein relate to the field of inkjet printer technology, and more specifically, to a floating buffer type high-speed inkjet printer. Background Technology
[0002] A coding machine is a software-controlled device that marks products or packaging in a non-contact manner. It can be used to print characters (such as production date, shelf life, batch number, etc.), icons, specifications, barcodes, and anti-counterfeiting labels on the product surface.
[0003] In existing technologies, floating buffer high-speed inkjet printers are devices that improve the quality and stability of high-speed inkjet printing through a floating buffer mechanism. This mechanism uses a buffer device to create a floating connection between the printhead and the fixed frame. When the printhead encounters vibration, impact, or uneven product surfaces during high-speed printing, the floating buffer absorbs and buffers these external forces, reducing the impact on the printhead and maintaining relative stability between the printhead and the product surface, thus ensuring the accuracy and clarity of the printing. However, this type of floating buffer high-speed inkjet printer often experiences over-buffering during printing, leading to significant displacement of the printhead and affecting the accuracy and stability of the printing. Summary of the Invention
[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a floating buffer type high-speed inkjet printer to solve the technical problem that excessive buffering often occurs during the inkjet printing process in the prior art, resulting in large displacement of the printhead during the inkjet printing process, which affects the accuracy and stability of the inkjet printing.
[0005] According to one aspect, at least one embodiment of this disclosure provides a floating buffer type high-speed inkjet printer, including an inkjet printer body, the inkjet printer body being provided with an inkjet nozzle, and further comprising:
[0006] A fixing plate is elastically connected to one end of the inkjet printer body by four telescopic springs.
[0007] A telescopic limiting member is disposed inside the telescopic spring to support the fixed plate and limit the telescopic spring. When the telescopic spring retracts, it causes the fixed plate to move toward the telescopic limiting member.
[0008] A buffer assembly is disposed within the telescopic limiting member to reduce the displacement speed of the fixed plate and limit the position of the fixed plate.
[0009] Preferably, the telescopic limiting member includes:
[0010] A sleeve, one end of which is fixedly connected to one end of the inkjet printer body, and a telescopic spring is sleeved on the outside of the sleeve;
[0011] A connecting rod, one end of which is fixedly connected to one end of the fixed plate, and the connecting rod is slidably engaged with the sleeve.
[0012] Preferably, the buffer component includes:
[0013] Two horizontal plates are symmetrically arranged at both ends of the connecting rod;
[0014] A rubber pad is fitted on the horizontal plate, and a sliding groove that matches the rubber pad is provided on the inner side wall of the sleeve, which increases the friction between the connecting rod and the sleeve during movement.
[0015] A limiting member is disposed on the connecting rod and is used to limit the movement of the connecting rod.
[0016] Furthermore, the limiting member includes:
[0017] A limiting spring is provided, and a cavity is provided on the connecting rod. One end of the limiting spring is fixedly connected to the inner bottom wall of the cavity.
[0018] A limiting plate, one end of which is fixedly connected to the other end of the limiting spring;
[0019] A limiting hemisphere is provided, one end of which is fixedly connected to the other end of the limiting plate. The inner sidewall of the sleeve is provided with a plurality of limiting holes that cooperate with the limiting hemisphere. The limiting hemisphere compresses the limiting spring and transfers it into the cavity, so as to facilitate the movement of the connecting rod in the sleeve.
[0020] In order to allow for coding after buffering, a coding groove is provided on the fixed plate, and the cross-sectional area of the coding groove is larger than the cross-sectional area of the coding nozzle.
[0021] To increase the friction between the fixing plate and the item to be printed and to provide a buffering effect, four buffer pads are provided on the other end of the fixing plate, and the buffer pads correspond to the telescopic springs.
[0022] To prevent the limiting spring from moving out of the cavity and causing damage to the connecting rod during movement, the cross-sectional area of the limiting plate is larger than the cross-sectional area of the cavity and the bottom of the limiting hemisphere.
[0023] Preferably, the connecting rod has a movable groove that matches the movement trajectory of the limiting plate.
[0024] To prevent the telescopic spring from shifting, the axes of the telescopic spring and the sleeve are aligned, and the inner diameter of the telescopic spring's internal space is larger than the cross-sectional area of the sleeve.
[0025] In order to keep the fixing plate parallel to the end face of the inkjet printer body, all four sleeves are perpendicular to the fixing plate.
[0026] The beneficial effects of the embodiments disclosed herein are as follows:
[0027] In this disclosure, when the product to be printed vibrates during displacement, it will impact the fixing plate. This impact causes the telescopic spring to contract, the connecting rod to move towards the sleeve, and the movement of the connecting rod drives the limiting hemisphere to move. The limiting hemisphere compresses the limiting spring, causing the limiting spring to contract and move the limiting plate and the limiting hemisphere into the cavity. Once the limiting hemisphere is fully inside the cavity, the connecting rod can continue to move, passing through multiple limiting holes sequentially according to the displacement distance of the fixing plate. During this movement, the sleeve guides the telescopic spring, preventing it from shifting. This avoids excessive spring contraction and buffering. When one end of the fixing plate contacts one end of the four sleeves, the sleeves fix and limit the fixing plate, making it difficult for it to move further. At this point, the fixing plate is in close and stable contact with the product to be printed, allowing for stable printing. Attached Figure Description

[0037] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.
[0038] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0039] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.
[0040] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.
[0042] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0043] As shown in Figures 1 to 7, a floating buffer type high-speed inkjet printer is shown in one embodiment of the present disclosure. It includes an inkjet printer body 1, an inkjet printer nozzle 2 is provided on the inkjet printer body 1, and an inkjet printer groove 15 is provided on the fixed plate 3 in order to perform inkjet printing after buffering. The cross-sectional area of the inkjet printer groove 15 is larger than the cross-sectional area of the inkjet printer nozzle 2. It also includes a fixed plate 3, a telescopic limiting member and a buffer assembly.
[0044] The fixed plate 3 is elastically connected to one end of the inkjet printer body 1 by four telescopic springs 4. In order to increase the friction between the fixed plate 3 and the item to be printed and to play a buffering role, four buffer pads 16 are provided on the other end of the fixed plate 3. The buffer pads 16 correspond to the telescopic springs 4 and are close to the four corners of the fixed plate 3.
[0045] The telescopic limiting component is located inside the telescopic spring 4 to support the fixed plate 3 and limit the telescopic spring 4. When the telescopic spring 4 retracts, it drives the fixed plate 3 to move toward the telescopic limiting component. The telescopic limiting component includes a sleeve 5 and a connecting rod 6. One end of the sleeve 5 is fixedly connected to one end of the inkjet printer body 1. The telescopic spring 4 is sleeved on the outside of the sleeve 5. One end of the connecting rod 6 is fixedly connected to one end of the fixed plate 3. The connecting rod 6 and the sleeve 5 are in sliding fit. In order to prevent the telescopic spring 4 from shifting, the axes of the telescopic spring 4 and the sleeve 5 are coincident, and the inner diameter of the internal space of the telescopic spring 4 is larger than the cross-sectional area of the sleeve 5. In order to keep the fixed plate 3 parallel to the end face of the inkjet printer body 1, all four sleeves 5 are perpendicular to the fixed plate 3. When the fixed plate 3 is impacted or collided, multiple telescopic springs 4 retract, and the connecting rod 6 slides close to the sleeve 5. The sleeve 5 plays a guiding role for the telescopic spring 4, which can keep the telescopic spring 4 perpendicular to the fixed plate 3 and prevent it from shifting.
[0046] The buffer assembly is located within the telescopic limiting member to slow down the displacement speed of the fixed plate 3 and limit its movement. The buffer assembly includes two horizontal plates 7, a rubber pad 8, and a limiting member. The two horizontal plates 7 are symmetrically arranged at both ends of the connecting rod 6. The rubber pad 8 is fitted onto each horizontal plate 7. A groove 9, which mates with the rubber pad 8, is provided on the inner wall of the sleeve 5. This increases the friction between the connecting rod 6 and the sleeve 5 during movement. When the connecting rod 6 moves, the frictional resistance generated between the rubber pad 8 and the groove 9 can buffer the spring's contraction. A limiting element is installed on the connecting rod 6 to limit its movement. This limiting element includes a limiting spring 10, a limiting plate 12, and a limiting hemisphere 13. A cavity 11 is formed in the connecting rod 6. One end of the limiting spring 10 is fixedly connected to the inner bottom wall of the cavity 11, and one end of the limiting plate 12 is fixedly connected to the other end of the limiting spring 10. To prevent the limiting spring 10 from moving out of the cavity 11 and breaking during the movement of the connecting rod 6, the cross-sectional area of the limiting plate 12 is larger than the cross-sectional area of the bottom of the cavity 11 and the limiting hemisphere 13. A cavity 11 is formed inside the connecting rod 6. The sleeve 5 has a movable groove 17 that matches the movement trajectory of the limiting plate 12. One end of the limiting hemisphere 13 is fixedly connected to the other end of the limiting plate 12. Multiple limiting holes 14 that match the limiting hemisphere 13 are provided on the inner wall of the sleeve 5. The limiting hemisphere 13 compresses the limiting spring 10 and transfers it into the cavity 11. The surface of the limiting hemisphere 13 is smooth, facilitating the movement of the connecting rod 6 within the sleeve 5. The movement of the fixed plate 3 causes the connecting rod 6 to move, and the telescopic spring 4 retracts. The movement of the connecting rod 6 causes the limiting hemisphere 13 to move, and the limiting hemisphere 13 compresses... When the limiting spring 10 is compressed, it contracts, causing the limiting plate 12 and the limiting hemisphere 13 to move into the cavity 11. Once the limiting hemisphere 13 is fully inside the cavity 11, the connecting rod 6 can continue to move and pass through multiple limiting holes 14 in sequence according to the displacement distance of the fixing plate 3. When one end of the fixing plate 3 contacts one end of the four sleeves 5, the sleeves 5 fix and limit the fixing plate 3, making it difficult for the fixing plate 3 to continue moving. At this time, the fixing plate 3 is in close and stable contact with the product to be printed, and printing can be performed.
[0047] Working principle: When it is time to print on the product, the user holds the floating buffer high-speed inkjet printer, aligns the printing slot 15 with the printing area, and moves it towards the product, bringing the fixing plate 3 into contact with the product. The user holds the inkjet printer body 1 and generates a pushing force, causing the buffer pad 16 to contact the product first. When the product shakes or vibrates during the displacement, it will impact the fixing plate 3. At this time, the telescopic spring 4 retracts, and the connecting rod 6 moves towards the sleeve 5. The movement of the connecting rod 6 drives the limiting hemisphere 13 to move, which in turn compresses the limiting spring 10. The limiting spring 10 retracts, causing the limiting plate 12 and the limiting... The limiting hemisphere 13 moves into the cavity 11. Once the limiting hemisphere 13 is fully inside the cavity 11, the connecting rod 6 can continue to move and pass through multiple limiting holes 14 in sequence according to the displacement distance of the fixing plate 3. During the movement, the sleeve 5 guides the telescopic spring 4 to prevent the telescopic spring 4 from deviating. This avoids excessive spring contraction and excessive buffering. When one end of the fixing plate 3 contacts one end of the four sleeves 5, the sleeves 5 fix and limit the fixing plate 3, making it difficult for the fixing plate 3 to continue moving. At this time, the fixing plate 3 is in close and stable contact with the product to be printed, and printing can be performed.
[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
