Description

Technical Field

[0001] This invention relates to the field of liquor bottle cap processing technology, and in particular to an intelligent printing device for liquor bottle caps. Background Technology

[0002] Bottle caps are used in various industries. After many bottle caps are produced, their surfaces need to be printed with corresponding patterns, text, and colors to form the logo of the products they sell. As a result, automated printing equipment for printing patterns on bottle caps has appeared on the market.

[0003] A bottle cap printing machine with positioning function, such as "CN214873501U", includes a main body, a printing component, an electric telescopic rod, and a third spring. The printing component is located inside the main body, and the electric telescopic rod is fixed inside the main body. A second spring is located inside the main body, and a first moving rod is connected to the outside of the second spring. A second moving rod is connected to the outside of the first spring. A limit plate is provided on the outside of the placement box, and a third spring is connected to the outside of the telescopic block. This bottle cap printing machine with positioning function is equipped with a fixed plate and a fixed rod. The fixed plate can move the fixed rod to fix the bottle cap, facilitating printing. Multiple bottle caps can be fixed simultaneously, increasing work efficiency. Furthermore, fixing the bottle caps before printing prevents printing quality issues caused by failure to fix them properly.

[0004] However, in the existing technology, such as the bottle cap printing in the aforementioned patent, it is suitable for single-color printing, but not for multi-color printing of inks. In the existing technology, multi-color printing usually uses a conveyor belt to transport the bottle cap after printing one color to the next printing location for printing the next color, until all colors are printed. However, during the transfer of bottle caps in the middle, the bottle caps are prone to shifting on the conveyor belt, causing the position of the color to not match the previous color when registering, resulting in a blurry final pattern and affecting product quality. Summary of the Invention

[0005] In view of the aforementioned existing problems, the present invention is proposed.

[0006] The purpose of this invention is to solve the problem of bottle cap position easily shifting during transportation in the prior art when multi-color printing is carried out.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0008] On one hand, the present invention provides a smart printing device for liquor bottle caps, which includes a base, a rotating seat, and printing mechanisms. The rotating seat is intermittently rotated and disposed above the base. Multiple limiting grooves are provided at the edge of the rotating seat, and clamping mechanisms are provided in the limiting grooves. Multiple printing mechanisms are provided and are positioned corresponding to the positions above the clamping mechanisms. A discharge conveyor belt, a feeding conveyor belt, and a dust removal mechanism are provided at the edge of the base. The discharge conveyor belt, the feeding conveyor belt, the dust removal mechanism, and the multiple printing mechanisms are arranged in a ring at equal intervals at the edge of the base. Fixed rails are symmetrically provided on the rotating seats on both sides below the limiting grooves. Sliding plates are slidably disposed within the fixed rails and are driven to slide by magnetic plates. One end of the discharge conveyor belt is located directly below the limiting groove, and one end of the feeding conveyor belt is located directly above the limiting groove.

[0009] Furthermore, the printing mechanism includes a first support base, a first cylinder, and a printing head. The upper end of the first support base is connected to the printing head via the first cylinder. The printing head is located directly above the limiting groove. During printing, the printing head is extended to the printing position inside the bottle cap by driving the first cylinder to perform printing.

[0010] Furthermore, a second support seat is provided above the base, and a limiting frame is provided at the upper end of the second support seat. One end of the limiting frame is slidably disposed below the rotating seat. One end of the feeding conveyor belt extends into the interior of the limiting frame. A feeding space is left between the end face of the limiting frame and the end of the feeding conveyor belt facing the rotating seat. When feeding, the bottle caps on the feeding conveyor belt fall directly into the limiting groove, and the bottle caps can be clamped by the clamping mechanism. The limiting frame is set to limit the bottle caps during the falling process to prevent them from falling into the limiting groove inaccurately.

[0011] Furthermore, the dust removal mechanism includes a third support base, a dust cover, and a fan. The third support base is located above the base, and the upper end of the third support base is connected to the dust cover via a second cylinder. The fan is located on the upper end of the third support base, and the air inlet of the fan is connected to the inside of the dust cover via an air duct. Cleaning the inside of the bottle cap before printing ensures that the bottle cap is clean. By starting the fan, the dust inside the bottle cap can be sucked out.

[0012] Furthermore, a fixed frame is provided at the center of the upper part of the base, and a rotating shaft is rotatably provided inside the fixed frame. The rotating seat is rotatably arranged above the fixed frame and linked with the rotating shaft. The upper end of the rotating shaft extends to the upper end of the rotating seat and is provided with lamp tubes. Multiple lamp tubes are provided. The fixed frame is used to stably support the rotating seat. The lamp tubes continuously irradiate the bottle cap, which can accelerate the hardening of the ink after printing.

[0013] Furthermore, a side groove is provided on one side of the fixing frame, a first gear is rotatably provided on the top of the base, and an end gear is provided at the lower end of the rotating shaft. The side wall of the first gear extends into the side groove and meshes with the end gear. A motor is provided on the base, and a second gear is linked to the output end of the motor. The first gear and the second gear are linked together. By driving the motor to drive the second gear to rotate, the first gear and the rotating shaft are driven to rotate, thereby realizing the rotation of the rotating seat.

[0014] Furthermore, a fixing plate is provided between the two fixed rail end faces. The fixing plate is assembled and connected to the sliding plate by a first spring. The magnetic plate is set with a right-angle structure. One end of the magnetic plate is assembled and connected to the outside of the fixing frame, and the other end is assembled and connected to the bottom of the fixing plate. The sliding plate is a magnetic structure that repels the magnetic plate. The magnetic plate is located at the unloading conveyor belt position. When the rotating seat rotates to the unloading position, the sliding plate below the limiting groove at this position gradually approaches the magnetic plate. Since the magnetic plate and the sliding plate repel each other, when it is located at the unloading conveyor belt position, the sliding plate slides open in the fixed rail and opens the clamping mechanism at the same time. The bottle cap loses its limit and can be unloaded.

[0015] Furthermore, the clamping mechanism includes a fixed box and a limiting shaft. The fixed box has two symmetrically arranged rotating seats on both sides of the limiting groove. Multiple assembly slots are evenly opened in the fixed box. Multiple limiting shafts are provided and slidably arranged in the corresponding assembly slots. The assembly slots are connected to the limiting shafts by a second spring. When the bottle cap is placed between the two fixed boxes, the limiting shafts move towards the bottle cap under the pushing action of the second spring. The limiting shafts that contact the bottle cap abut against the corresponding parts of the bottle cap. The close cooperation of the limiting shafts can achieve stable clamping of the bottle cap.

[0016] Furthermore, a magnetic block is provided at the end of the limiting shaft facing the assembly groove. The assembly groove is located inside a fixed box at one end, which is equipped with a magnetic plate that is attracted to the magnetic block. The magnetic plate is electrically connected to an external power source. Before clamping the bottle cap, the magnetic plate is energized to generate magnetism, attracting the magnetic block and moving all the limiting shafts into the assembly groove. After the bottle cap is placed between the two fixed boxes, the power to the magnetic plate is turned off, and the second spring pushes the limiting shaft to move outward, thus achieving stable clamping of the bottle cap.

[0017] Furthermore, an anti-slip layer is provided on the outer side of the limiting shaft, and a buffer pad is provided on the end face of the limiting shaft. The anti-slip layer can increase the friction between the limiting shaft and the bottle cap, and the buffer pad can reduce the squeezing force between the end face of the limiting shaft and the bottle cap, thus avoiding scratches on the surface of the bottle cap.

[0018] The beneficial effects of this invention are:

[0019] In this invention, during the printing operation on bottle caps, the bottle caps are placed on a feeding conveyor belt beforehand. The conveyor belt guides a bottle cap into a limiting groove, where it rests on a sliding plate. Its sides are clamped and limited by a clamping mechanism. When the rotating seat rotates to the dust removal mechanism, the dust cover on the dust removal mechanism moves down and covers the bottle cap opening. A fan sucks out the dust from inside the bottle cap, ensuring its cleanliness. The rotating seat continues to rotate, moving to a printing mechanism where the printing head performs the initial printing on the inside of the bottle cap. Irradiation by a lamp accelerates the hardening of the ink. The device then rotates again to the next printing head. The printing process continues until all colors are printed. The rotating seat continues to rotate and moves to the unloading conveyor belt position. Due to the repulsion between the sliding plate and the magnetic plate, the sliding plate can be pushed away from the magnetic plate. At this time, the sliding plate slides in the fixed rail until it removes the limiting groove and opens the clamping mechanism. The bottle cap in the limiting groove falls onto the unloading conveyor belt, and the printed product is transferred away by the unloading conveyor belt. When the bottle cap is clamped by the clamping mechanism, it is always in a stable state. Even when the rotating seat rotates to adjust the position, the bottle cap will not shift in angle or position, so that the positioning point for each printing is in the same place, ensuring printing quality.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, as used herein, "an embodiment" or "embodiment" refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0035] Please see Figures 1-9This invention provides a technical solution: a smart printing device for liquor bottle caps, including a base 1, a rotating seat 2, and printing mechanisms. The rotating seat 2 is intermittently rotated and positioned above the base 1. Multiple limiting grooves 3 are provided at the edge of the rotating seat 2, and clamping mechanisms are provided in the limiting grooves 3. Multiple printing mechanisms are provided and are positioned corresponding to the positions above the clamping mechanisms. The edge of the base 1 is provided with an unloading conveyor belt 411, a feeding conveyor belt 412, and a dust removal mechanism 413. The unloading conveyor belt 411, the feeding conveyor belt 412, the dust removal mechanism 413, and the multiple printing mechanisms are arranged in a ring at equal intervals at the edge of the base 1. Fixed rails 511 are symmetrically provided on the rotating seats 2 on both sides below the limiting grooves 3. Slide plates 512 are slidably provided in the fixed rails 511. The slide plates 512 are driven to slide by magnetic plates 513. One end of the unloading conveyor belt 411 is located directly below the limiting grooves 3, and one end of the feeding conveyor belt 412 is located directly above the limiting grooves 3.

[0036] like Figures 1-9 As shown, the printing mechanism includes a first support base 611, a first cylinder 612, and a printing head 613. The upper end of the first support base 611 is connected to the printing head 613 via the first cylinder 612. The printing head 613 is located directly above the limiting groove 3. During the printing operation, the printing head 613 is extended to the printing position inside the bottle cap by driving the first cylinder 612 to perform printing.

[0037] like Figures 1-9 As shown, a second support base 4121 is provided above the base 1, and a limiting frame 4122 is provided at the upper end of the second support base 4121. One end of the limiting frame 4122 is slidably disposed above the rotating seat 2. One end of the feeding conveyor belt 412 extends into the limiting frame 4122. There is a feeding space between the end face of the limiting frame 4122 and the end of the feeding conveyor belt 412 facing the rotating seat 2. When feeding, the bottle caps on the feeding conveyor belt 412 fall directly to the top of the limiting groove 3. The bottle caps can be clamped by the clamping mechanism. The limiting frame 4122 is set to limit the bottle caps during the falling process to prevent them from falling into the limiting groove 3 inaccurately.

[0038] like Figures 1-9 As shown, the dust removal mechanism 413 includes a third support base 4131, a dust cover 4132, and a fan 4133. The third support base 4131 is located above the base 1. The upper end of the third support base 4131 is connected to the dust cover 4132 via a second cylinder 4134. The fan 4133 is located on the upper end of the third support base 4131. The air inlet of the fan 4133 is connected to the inside of the dust cover 4132 via an air duct 4135. The dust removal mechanism 4133 cleans the inside of the bottle cap before printing, ensuring that the bottle cap is clean. The dust inside the bottle cap can be sucked out by starting the fan 4133.

[0039] like Figures 1-9As shown, a fixed frame 711 is provided at the center of the upper part of the base 1. A rotating shaft 712 is rotatably provided inside the fixed frame 711. The rotating seat 2 is rotatably positioned above the fixed frame 711 and linked with the rotating shaft 712. The upper end of the rotating shaft 712 extends to the upper end of the rotating seat 2 and is provided with lamp tubes 713. Multiple lamp tubes 713 are provided. The fixed frame 711 is used to stably support the rotating seat 2. The lamp tubes 713 continuously irradiate the bottle cap, which can accelerate the hardening of the ink after printing.

[0040] like Figures 1-9 As shown, a side groove 721 is provided on one side of the fixed frame 711, a first gear 723 is rotatably provided on the top of the base 1, and an end gear 722 is provided at the lower end of the rotating shaft 712. The side wall of the first gear 723 extends into the side groove 721 and meshes with the end gear 722. A motor 724 is provided on the base 1, and a second gear 725 is linked to the output end of the motor 724. The first gear 723 and the second gear 725 are linked. By driving the motor 724 to drive the second gear 725 to rotate, the first gear 723 and the rotating shaft 712 will be driven to rotate, thereby realizing the rotation of the rotating seat 2.

[0041] like Figures 1-9 As shown, a fixing plate 731 is provided between the end faces of the two fixed rails 511. The fixing plate 731 is assembled and connected to the slide plate 512 through the first spring 732. The magnetic plate 513 is set with a right angle structure. One end of the magnetic plate 513 is assembled and connected to the outside of the fixing frame 711, and the other end is assembled and connected to the bottom of the fixing plate 731. The slide plate 512 is a magnetic structure that repels the magnetic plate 513. The magnetic plate 513 is located at the unloading conveyor belt 411. When the rotating seat 2 rotates to the unloading position, the slide plate 512 below the limiting groove 3 at this position gradually approaches the magnetic plate 513. Since the magnetic plate 513 and the slide plate 512 repel each other, when it is located at the unloading conveyor belt 411, the slide plate 512 slides open in the fixed rail 511, and at the same time opens the clamping mechanism. The bottle cap loses its limit and can be unloaded.

[0042] like Figures 1-9 As shown, the clamping mechanism includes a fixed box 811 and a limiting shaft 812. The fixed box 811 has two rotating seats 2 symmetrically arranged on both sides of the limiting groove 3. Multiple assembly slots 813 are evenly opened in the fixed box 811. Multiple limiting shafts 812 are provided and slidably arranged in the corresponding assembly slots 813. The assembly slots 813 are connected to the limiting shafts 812 by a second spring 814. When the bottle cap is placed between the two fixed boxes 811, the limiting shafts 812 move towards the bottle cap under the pushing action of the second spring 814. The limiting shafts 812 that contact the bottle cap abut against the corresponding part of the bottle cap. The close cooperation of the limiting shafts 812 can achieve stable clamping of the bottle cap.

[0043] like Figures 1-9As shown, a magnetic block 821 is provided at the end of the limiting shaft 812 facing the assembly groove 813. The assembly groove 813 is located inside the fixing box 811 at one end, which is equipped with a magnetic plate 822 that is attracted to the magnetic block 821. The magnetic plate 822 is electrically connected to an external power source. Before clamping the bottle cap, the magnetic plate 822 is energized to generate magnetism, attracting the magnetic block 821 and attracting all the limiting shafts 812 to move into the assembly groove 813. After the bottle cap is placed between the two fixing boxes 811, the magnetic plate 822 is de-energized, and the second spring 814 pushes the limiting shaft 812 to move outward, which can achieve stable clamping of the bottle cap.

[0044] like Figures 1-9 As shown, the outer side of the limiting shaft 812 is provided with an anti-slip layer 831, and the end face of the limiting shaft 812 is provided with a buffer pad 832. By setting the anti-slip layer 831, the friction between the limiting shaft 812 and the bottle cap can be increased. The setting of the buffer pad 832 can reduce the squeezing force between the end face of the limiting shaft 812 and the bottle cap, and avoid scratching the surface of the bottle cap.

[0045] Working principle: When printing on bottle caps, the bottle caps are placed on the feeding conveyor belt 412 in advance. The feeding conveyor belt 412 guides a bottle cap into a limiting groove 3. The bottle cap falls onto the sliding plate 512, and its side is clamped and limited by the clamping mechanism. When the rotating seat 2 rotates to the position of the dust removal mechanism 413, the dust cover 4132 on the dust removal mechanism 413 moves down and covers the bottle cap opening. The fan 4133 sucks out the dust inside the bottle cap, ensuring that the inside of the bottle cap is clean. The rotating seat 2 continues to rotate and moves to a printing mechanism. The printing head 613 on the printing mechanism performs the initial printing on the inside of the bottle cap. The ink hardening is accelerated by the illumination of the lamp tube 713. Then it rotates again to the next printing head 613. Below, printing continues until all colors are printed. The rotating seat 2 continues to rotate and moves to the position of the unloading conveyor belt 411. Since the sliding plate 512 and the magnetic plate 513 repel each other, the sliding plate 512 can be pushed away from the magnetic plate 513. At this time, the sliding plate 512 slides in the fixed rail 511 until the sliding plate 512 removes the limiting groove 3 and opens the clamping mechanism. The bottle cap in the limiting groove 3 falls onto the unloading conveyor belt 411. The printed product can be transferred away by the unloading conveyor belt 411. When the bottle cap is clamped by the clamping mechanism, it is always in a stable state. Even when the rotating seat 2 rotates to adjust the position, the bottle cap will not shift in angle or position, so that the positioning point of each printing is in the same place, ensuring the printing quality.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention 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 the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
