Description

Technical Field

[0001] This invention relates to the field of bottle cap marking printing apparatus and method. Background Technology

[0002] Regarding Figure 1 Printing character markings above the bottle cap with the curved groove shown presents the following technical challenges:

[0003] First, the rods, or carriers, used to support the bottle caps have difficulty correcting the angle difference between the marking area and the printing plate before printing, causing the actual printing area to deviate. Figure 1 The marked area.

[0004] Secondly, the solution of manually correcting the bottle cap's angle deviation is inaccurate and will disrupt the production rhythm of the entire production line in industrialized production, which is not worth the effort.

[0005] Therefore, based on the above explanation, it is necessary to introduce specialized printing equipment for bottle caps with an arc-shaped groove at the top. Summary of the Invention

[0006] The purpose of this invention is to provide a bottle cap marking printing device and printing method to solve the above-mentioned technical problems.

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

[0008] A bottle cap marking printing device includes a second drive member, a positioning sleeve, and a rotating sleeve that fits around the positioning sleeve and rotates in cooperation with the positioning sleeve.

[0009] The top opening of the positioning sleeve is the first extension of the positioning sleeve that extends upward to the non-driving part of the second driving member, and the junction of the first extension of the positioning sleeve and the positioning sleeve is the outwardly expanding second extension of the positioning sleeve.

[0010] The top and bottom openings of the sleeve are respectively the first extension and the second extension of the sleeve. The second extension of the sleeve is surrounded by a number of pressure rods. From top to bottom, the pressure rods are the first rod that elastically cooperates with the first extension of the sleeve, the curved part that is always located above the second extension of the sleeve, and the second rod that is restricted by the movement of the second extension of the sleeve and extends downward relative to the bottom of the second extension of the sleeve.

[0011] Several sliding grooves are arranged around the corner of the first extension and the second extension of the positioning sleeve, wherein each sliding groove is adapted to a slider, and the slider and the corresponding sliding groove have an elastic sliding fit.

[0012] In combination with the number of capping rods that fail to insert into the curved groove of the bottle cap, multiple wheel frames are set up, and multiple wheel frames are continuously fixedly connected with multiple sliders. Each wheel frame passes through the second extension of the positioning sleeve and extends downward to the curved part of the capping rod. In addition, the downward extension part of the slider is equipped with a rotating wheel that has a height difference with the curved part of the capping rod.

[0013] It also includes a motor that drives the rotating sleeve to rotate axially around the positioning sleeve. When the positioning sleeve is closed on the top of the bottle cap, the motor drives the rotating sleeve to rotate, causing all the capping rods that fail to insert into the curved groove of the bottle cap to lift up all the wheel frame and wheel assembly based on the rolling contact between the curved part of the capping rod and the rotating wheel, thereby adjusting the angle difference between the bottle cap marking area and the printing area.

[0014] Preferably, the motor is de-energized after all the wheel frames and wheels are lifted.

[0015] Preferably, it also includes a printing plate located inside the positioning sleeve and subjected to downward or upward pressure by the second driving member, wherein the bottom of the printing plate is provided with an engraving area, and the center line of the engraving area coincides with the center line of multiple wheel frames.

[0016] Preferably, the second driving member is powered on after the motor that drives the rotating sleeve to rotate is de-energized, and drives the printing plate to press down on the bottle cap marking area.

[0017] Preferably, a limiting rod is provided in the groove to guide the slider to slide up and down, and a second spring is looped around the limiting rod to pull the slider to slide down.

[0018] It also includes sensor plates corresponding to multiple wheel frames one by one. The sensor plates are inserted into the slide grooves and are located in the sliding path of the sensor plate slider. When all the capping rods that fail to insert into the cap arc groove lift up all the wheel frames and the wheel assembly, the slider contacts all the sensor plates, so that the second drive unit is energized.

[0019] Preferably, it also includes a frame positioning sleeve and a rotating sleeve housing, wherein the housing serves as a support for the second drive member, and the housing also has housing extensions on both sides for fixing the motor.

[0020] Preferably, the motor is equipped with a roller that has a frictional rolling contact with the outer surface of the second extension of the sleeve, so that when the motor is energized, the sleeve is driven to rotate axially around the positioning sleeve based on the roller.

[0021] Preferably, it also includes a first driving member for driving the positioning sleeve to press the bottle cap, and a sleeve that frames the outer shell and is fixedly connected to the outer shell. The sleeve is equipped with a partition, which is fixedly connected to the first driving member so that the outer shell moves synchronously when the first driving member presses down or pulls up the sleeve.

[0022] Preferably, a plurality of first springs corresponding one-to-one with the pressure cap rod are arranged around the bottom of the first extension of the screw sleeve, wherein one end of the pressure cap rod is fixedly connected to the first extension of the screw sleeve, and the other end of the pressure cap rod is fixedly connected to the first rod in the pressure cap rod.

[0023] A printing method for a bottle cap label printing device, comprising the following printing steps:

[0024] 1) The bottle cap is conveyed by a conveyor mechanism with a support rod to the bottle cap marking printing device directly below. The first drive unit drives the outer shell to move downward. The positioning sleeve that is connected to the outer shell approaches and contacts the bottle cap. In this way, part of the capping rod enters the arc-shaped groove on the top of the bottle cap, and the remaining capping rod pushes against the top of the bottle cap. With the top of the bottle cap as a solid base, it moves upward relative to the second extension of the screw sleeve.

[0025] 2) By combining all the capping rods that are not inserted into the curved groove of the bottle cap, we can determine whether they lift all the pre-set wheel frames to determine the angle difference between the bottle cap marking area and the engraving area. That is, if any wheel frame is not lifted, the bottle cap marking area and the engraving area are misaligned. Conversely, when all the wheel frames are lifted, the bottle cap marking area and the engraving area are aligned and coincident.

[0026] 3) Based on the settings, the motor drives the rotating sleeve to rotate. Based on the rolling contact between the curved part of the capping rod and the rotating wheel, it lifts up the assembly of all the wheel frames and rotating wheels, adjusts the angle difference between the bottle cap marking area and the printing area. After the angle difference is corrected, the second driving component drives the printing plate to move downward to engrave the bottle cap marking area.

[0027] The beneficial effects of this invention are:

[0028] This invention determines the angle difference between the bottle cap marking area and the engraving area by whether the capping rod that is not inserted into the curved groove of the bottle cap lifts all the pre-set wheel frames. Accordingly, if any wheel frame is not lifted, the bottle cap marking area and the engraving area are misaligned. Conversely, when all the wheel frames are lifted, the bottle cap marking area and the engraving area are aligned and coincident. Attached Figure Description

[0040] To make the technical means, creative features, achieved objectives, and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this invention and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention.

[0041] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0042] Example 1

[0043] This embodiment presents a bottle cap marking printing device; please refer to [link / reference]. Figures 1-10 The bottle cap marking printing device includes a second driving member 4, a positioning sleeve 23 fixedly connected to the non-driving part of the second driving member 4, and a ring-shaped positioning sleeve 23 and a rotating sleeve 25 rotatably engaged with the positioning sleeve 23.

[0044] For further explanation, please refer to Figures 7-9 The top opening of the positioning sleeve 23 is the first extension 10 of the positioning sleeve that extends upward to the non-driving part of the second driving member 4. In addition, the junction of the first extension 10 of the positioning sleeve and the positioning sleeve 23 is the outwardly expanding second extension 14 of the positioning sleeve.

[0045] Please continue reading. Figures 7-9 Regarding the swivel sleeve 25, its top opening is an outwardly expanding first extension 24 of the swivel sleeve, and its bottom opening is an outwardly expanding second extension 17 of the swivel sleeve. It should be noted that the outward expansion radius of the second extension 14 of the positioning sleeve is greater than the outward expansion radius of the first extension 24 of the swivel sleeve.

[0046] Please see Figures 5-8 The outer peripheral wall of the second extension of the sleeve 17 is surrounded by a plurality of pressure rods 16 (the outer peripheral wall of the second extension of the sleeve 17 is provided with a plurality of rod grooves 26 for limiting the movement of the pressure rods 16). The pressure rods 16 are, from top to bottom, a first rod that elastically engages with the first extension of the sleeve 24, a curved portion that is always located above the second extension of the sleeve 17, and a second rod that is restricted by the movement of the second extension of the sleeve 17 and extends downward relative to the bottom of the second extension of the sleeve 17.

[0047] Please see Figures 5-7 A plurality of sliding grooves 13 are arranged around the corner of the first extension 10 and the second extension 14 of the positioning sleeve. Each sliding groove 13 is fitted with a slider 12, and the slider 12 has an elastic sliding fit with the corresponding sliding groove 13.

[0048] It is important to note that in this embodiment, multiple wheel frames 11 need to be set up according to the number of capping rods 16 that fail to be inserted into the curved groove of the bottle cap.

[0049] To further explain, when all the capping rods 16 move into contact with the top of the bottle cap as the positioning sleeve 23 abuts against it, there are two states:

[0050] ① Part of the capping rod 16 enters the arc-shaped groove on the top of the bottle cap (the depth of the arc-shaped groove is greater than the amount by which the capping rod 16 extends downward relative to the second extension 17 of the screw sleeve), and this part of the capping rod 16 does not move.

[0051] ②The remaining capping rod 16 presses against the top of the bottle cap, thereby moving upward relative to the second extension 17 of the screw sleeve, with the top of the bottle cap as a solid base.

[0052] Based on the above explanation, the core of this embodiment is as follows:

[0053] ①Perception Figure 1 ② Correction of the angle difference between the marked area and the engraved area; Figure 1The angle difference between the marked area and the engraved area shown.

[0054] In order to achieve the above core objective, the multiple wheel frames 11 are continuously and fixedly connected with multiple sliders 12. To further explain, each wheel frame 11 passes through the second extension 14 of the positioning sleeve and extends downward to the curved part of the pressure cover rod 16. In addition, the downward extended part of the slider 12 is equipped with a rotating wheel 21 that has a height difference with the curved part of the pressure cover rod 16.

[0055] Please see Figure 4 The bottle cap marking printing device also includes a motor 5 that drives the rotating sleeve 25 to rotate axially around the positioning sleeve 23. When the positioning sleeve 23 is closed on the top of the bottle cap, the motor 5 first needs to determine the angle difference between the bottle cap marking area and the engraving area by combining whether all the capping rods 16 that are not inserted into the bottle cap arc groove have lifted all the pre-set wheel frames 11. That is, if any wheel frame 11 is not lifted, then the bottle cap marking area is deviated from the engraving area. Conversely, when all the wheel frames 11 are lifted, then the bottle cap marking area and the engraving area are aligned and coincident.

[0056] Based on the above settings, the motor 5 drives the sleeve 25 to rotate. Based on the rolling contact between the curved part of the capping rod 16 and the rotating wheel 21, the assembly of all the wheel frames 11 and the rotating wheel 21 is lifted up, and the angle difference between the bottle cap marking area and the printing area is adjusted.

[0057] To further explain, the motor 5 is de-energized after all the wheel frames 11 and the rotating wheels 21 are lifted. Additionally, in this embodiment, a printing plate 22 located within the positioning sleeve 23 is pressed down or pulled up by the second driving member 4. The bottom of the printing plate 22 has an engraving area, the center line of which coincides with the center line of the multiple wheel frames 11. Thus, the second driving member 4 is energized after the motor 5 driving the rotating sleeve 25 is de-energized, thereby combining... Figure 7 The push rod 9 shown drives the printing plate 22 to press down onto the bottle cap marking area.

[0058] For details, please refer to Figures 6-9 A limiting rod 20 is provided in the slide groove 13 to guide the slider 12 to slide up and down. A second spring 19 is looped around the limiting rod 20 to pull the slider 12 to slide down. There are also sensing plates 18 corresponding to multiple wheel frames 11. The sensing plates 18 are inserted into the slide groove 13 and are located in the sliding path of the slider 12. Accordingly, when all the capping rods 16 that fail to insert into the cap arc groove lift up the combination of all wheel frames 11 and rotating wheels 21, the slider 12 contacts all the sensing plates 18, so that the second driving member 4 is energized.

[0059] The following points also need to be explained in this embodiment:

[0060] ①Please refer to Figures 2-4 The bottle cap marking printing device also includes a frame positioning sleeve 23 and a housing 6 for a rotating sleeve 25. The housing 6 serves as a support for the second driving member 4. Additionally, the housing 6 has housing extensions 7 on both sides for fixing the motor 5. The motor 5 is equipped with rollers 8, which have a frictional rolling contact with the outer surface of the second extension 17 of the rotating sleeve. This allows the motor 5 to drive the rotating sleeve 25 to rotate axially around the positioning sleeve 23 based on the rollers 8 after being energized.

[0061] ②The bottle cap marking printing device also includes a first driving member 1 for driving the positioning sleeve 23 to press the bottle cap, and a sleeve 2 that frames the outer shell 6 and is fixedly connected to the outer shell 6. The sleeve 2 is equipped with a partition 3, which is fixedly connected to the first driving member 1 and is used to make the outer shell 6 move synchronously when the first driving member 1 presses down or pulls up the sleeve 2.

[0062] ③A plurality of first springs 15 corresponding one-to-one with the pressure cap rod 16 are arranged around the bottom of the first extension 24 of the screw sleeve. One end of the pressure cap rod 16 is fixedly connected to the first extension 24 of the screw sleeve, and the other end of the pressure cap rod 16 is fixedly connected to the first rod in the pressure cap rod 16.

[0063] In this invention, unless otherwise explicitly 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. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0064] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
