DETAILED DESCRIPTION

[0028] The present invention provides Figures 1 to 11 The illustrated device for uniformly coating glue and rotating includes an operating table 1, a stand 2 fixedly mounted on the top of the operating table 1, the stand 2 being in an inverted L-shape, a gluing head 3 mounted on the lower surface of the top of the stand 2, a glue box, a delivery pump and other structures (not shown in the figure) being provided inside the operating table 1, and glue being delivered to the gluing head 3 by a delivery pipe; when coating the glue, the sphere 28 is fixed at a position below the gluing head 3, and glue is applied from top to bottom toward the sphere 28 through the gluing head 3, and the glue drips onto the top of the sphere 28 and flows around along the outer wall of the sphere 28, and the amount of glue is appropriate.

[0029] At the same time, a recovery bucket can be provided on the operating table 1 . The recovery bucket is located below the sphere 28 to recover the dripping glue and can be adjusted according to specific usage conditions.

[0030] In order to improve the stability of the glue, the ball 28 is fixed and evenly coated with glue, and the ball 28 is a Christmas ball with a mouth structure (refer to Figure 11 ), a horizontally distributed outer sleeve 5 is provided between the operating table 1 and the glue head 3, and a core rod 4 slides inside the outer sleeve 5. A through groove 27 for the core rod 4 to slide is provided on the stand 2, and the core rod 4 can also rotate inside the through groove 27. Balls are provided inside the through groove 27 to reduce friction.

[0031] A first fixed ring 16 is rotatably connected to the outer wall of the outer sleeve 5, and a connecting frame 17 is fixedly connected to the top of the first fixed ring 16. The connecting frame 17 is fixedly connected to the stand 2. The first fixed ring 16 and the connecting frame 17 are arranged so that the outer sleeve 5 can only rotate but cannot move up and down or left and right.

[0032] During use, a ball bearing or the like may be provided between the first fixed ring 16 and the outer sleeve 5 to ensure smooth rotation.

[0033] A slide groove 6 is provided on the outer wall of the core rod 4, and a slider 7 is provided inside the slide groove 6 for sliding. The slider 7 is fixedly connected to the inner wall of the outer sleeve 5, and a ball bearing can be provided between the slide groove 6 and the slider 7 to ensure smooth sliding.

[0034] The sliding groove 6 and the sliding block 7 are provided so that the core rod 4 and the outer sleeve 5 can rotate synchronously without affecting the sliding of the core rod 4 on the outer sleeve 5.

[0035] A centering sleeve 8 is fixed to the outside of the outer sleeve 5. The centering sleeve 8 can be made of, but is not limited to, hard rubber. The centering sleeve 8 is located at the end of the outer sleeve 5 away from the through groove 27. The centering sleeve 8 is close to the first fixed ring 16. The centering sleeve 8 is hollow and conical, and the outer diameter of the end away from the through groove 27 is small. The outer diameter is smaller than the inner diameter of the mouth of the sphere 28, and the outer diameter of the end of the centering sleeve 8 close to the through groove 27 is larger than the inner diameter of the mouth of the sphere 28. When the centering sleeve 8 is inserted into the mouth of the sphere 28, the opening of the mouth of the sphere 28 will abut against the middle position of the centering sleeve 8 (refer to Figure 6), at this time, the mouth of the sphere 28 is concentrically distributed with the centering sleeve 8, realizing automatic centering and facilitating subsequent uniform glue coating.

[0036] An elastic sleeve 9 is fixed to the end of the outer sleeve 5 close to the centering sleeve 8. The elastic sleeve 9 can be made of but not limited to rubber material. A cone head 10 is integrally formed at the end of the core rod 4 away from the through groove 27. The elastic sleeve 9 and the cone head 10 are both used to extend into the interior of the sphere 28, and the outer diameter of the cone head 10 close to the end of the core rod 4 is small, and the outer diameter at this point is smaller than the inner diameter of the elastic sleeve 9 away from the end of the outer sleeve 5 in the natural state (unsqueezed), which facilitates the cone head 10 to extend into the interior of the elastic sleeve 9, causing the elastic sleeve 9 to expand.

[0037] Specifically, before fixing the sphere 28 , the cone head 10 and the elastic sleeve 9 are in a staggered state, and the end of the elastic sleeve 9 away from the outer sleeve 5 is in a contracted state. Both the cone head 10 and the elastic sleeve 9 can extend into the interior of the sphere 28 from the mouth of the sphere 28 .

[0038] The operator holds the sphere 28, aligns its mouth with the position of the cone head 10, and moves the sphere 28 toward the centering sleeve 8. The cone head 10 and the elastic sleeve 9 both extend into the interior of the sphere 28, and the opening of the mouth of the sphere 28 abuts against the middle position of the centering sleeve 8. The core rod 4 is pulled away from the sphere 28, and the cone head 10 moves synchronously. The cone head 10 extends into the interior of the elastic sleeve 9, causing the elastic sleeve 9 to expand until the core rod 4 cannot move. The centering sleeve 8, the elastic sleeve 9, and the cone head 10 cooperate to achieve the positioning of the sphere 28.

[0039] By arranging structures such as the centering sleeve 8, the elastic sleeve 9, and the cone head 10, the positioning of the sphere 28 is achieved, and automatic centering is performed at the same time to ensure the stability of the glue coating.

[0040] During actual use, the operator can debug the moving distance of the core rod 4 in advance. For example, the positioning of the sphere 28 can be completed by moving 2 cm. The core rod 4 stops moving after moving 2 cm to avoid excessive squeezing of the sphere 28. The moving distance can be adjusted according to the size of the sphere 28 and other factors.

[0041] In order to realize the movement of the core rod 4 and the rotation of the core rod 4 and the outer sleeve 5, a support plate 25 is rotatably connected to the core rod 4, and the core rod 4 can rotate on the support plate 25. At the same time, the support plate 25 and the core rod 4 can move synchronously along the axial direction of the core rod 4; an electric push rod 26 is fixedly connected to the stand 2, and the support plate 25 is fixedly connected to the telescopic end of the electric push rod 26.

[0042] Specifically, the telescopic end of the electric push rod 26 is controlled to be retracted, and the core rod 4 is driven to move away from the sphere 28 through the support plate 25. The cone head 10 extends into the interior of the elastic sleeve 9, causing the elastic sleeve 9 to expand. The centering sleeve 8, the elastic sleeve 9, and the cone head 10 cooperate to achieve the positioning of the sphere 28.

[0043] The telescopic end of the electric push rod 26 is extended to drive the core rod 4 to move toward the sphere 28 through the support plate 25. The cone head 10 is extracted from the inside of the elastic sleeve 9, causing the elastic sleeve 9 to shrink and release the positioning of the sphere 28. At this time, the sphere 28 can be removed.

[0044] The support plate 25 is fixedly connected to a motor 22, a driving shaft of the motor 22 is fixedly connected to a first gear 23, and a core rod 4 is fixedly connected to a second gear 24, and the first gear 23 is meshed with the second gear 24; the motor 22 drives the first gear 23 to rotate, and since the first gear 23 is meshed with the second gear 24, the second gear 24 drives the core rod 4 to rotate, and with the cooperation of the slide groove 6 and the slider 7, the core rod 4 and the outer sleeve 5 rotate synchronously.

[0045] After the ball 28 is positioned, the motor 22 is activated to rotate the ball 28 .

[0046] The motor 22, the electric push rod 26 and other structures are all connected to the power supply of the factory.

[0047] To improve the stability of the positioning of the sphere 28 and prevent glue from flowing to the mouth of the sphere 28, a cap 11 is fixed to the outer sleeve 5. The cap 11 surrounds the outer side of the centering sleeve 8 and rotates synchronously with the outer sleeve 5. After the centering sleeve 8, the elastic sleeve 9, and the cone head 10 cooperate to position the sphere 28, the mouth of the sphere 28 is inserted into the interior of the cap 11, and the outer wall of the mouth is attached to the inner wall of the cap 11. The end of the cap 11 away from the first fixed ring 16 is attached to the curved outer wall of the sphere 28, thereby improving the stability of the positioning of the sphere 28 and ensuring the stability of the glue application.

[0048] At the same time, since the mouth of the sphere 28 needs to be docked with a metal cap or the like later, if glue remains at the mouth of the sphere 28 and dries into a block, it will affect the stability of the subsequent docking. The surrounding cap 11 surrounds and protects the outside of the mouth of the sphere 28 to prevent glue from dripping onto the mouth of the sphere 28, thereby avoiding affecting the subsequent use of the sphere 28.

[0049] And the operator can clean the outside of the cap 11 regularly.

[0050] By providing the surrounding cap 11 , the stability of the positioning of the sphere 28 is improved, and at the same time, glue is prevented from dripping onto the mouth of the sphere 28 , thereby protecting the sphere 28 .

[0051] Considering that after the glue drops on the top of the sphere 28, it is difficult to achieve uniform glue coating by simply rotating the sphere 28, in order to improve the glue coating efficiency without affecting the positioning of the sphere 28, an arc box 12 is provided below the sphere 28. The upper surface of the arc box 12 is a concave surface, which adapts to the shape of the sphere 28; and because the sphere 28 is an arc shape, if it is always kept in a horizontal state (the top is concave), it will affect the positioning of the sphere 28, thereby affecting the glue coating operation. In order to achieve the adjustment of the position of the arc box 12, the arc box 12 and the core rod 4 can be linked.

[0052] The bottom end of the first fixed ring 16 is fixedly connected to an ear block 18, and a first rocker arm 19 is rotatably provided at the bottom end of the ear block 18, and the middle section of the first rocker arm 19 is docked with the bottom end of the ear block 18, one end of the first rocker arm 19 is fixedly connected to the outer wall of the arc box 12, and the other end of the first rocker arm 19 extends to the top of the outer sleeve 5 and is rotatably connected to the second rocker arm 21; a second fixed ring 20 is rotatably provided on the core rod 4, and the end of the second rocker arm 21 away from the first rocker arm 19 is hinged to the second fixed ring 20.

[0053] When the core rod 4 drives the cone head 10 to move along the axis of the outer sleeve 5 and away from the sphere 28, the first swing rod 19 will be pulled through the second swing rod 21, and the end of the first swing rod 19 close to the second swing rod 21 will swing downward, while the other end of the first swing rod 19 can drive the arc box 12 to swing upward; when the core rod 4 drives the cone head 10 to move along the axis of the outer sleeve 5 and toward the sphere 28, the first swing rod 19 will be lifted through the second fixed ring 20 and the second swing rod 21, and the end of the first swing rod 19 close to the second swing rod 21 will swing upward, while the other end of the first swing rod 19 can drive the arc box 12 to swing downward.

[0054] The arc box 12 has an arc strip 13 on its arc surface for uniformly coating the glue.

[0055] When the arc box 12 and the arc bar 13 swing to the bottom position of the sphere 28, there is a glue gap between the arc bar 13 and the outer wall of the sphere 28. The glue gap is small, such as 0.1mm, and will not directly fit on the outer wall of the sphere 28. It can be adjusted according to specific usage.

[0056] In the initial state (the Christmas ball is not positioned), the cone head 10 and the elastic sleeve 9 are in a staggered state, the elastic sleeve 9 is in a retracted state away from the outer sleeve 5, and the cone head 10 and the elastic sleeve 9 can be extended into the interior of the sphere 28 from the mouth of the sphere 28, while the arc box 12 is tilted downward (refer to Figure 11 ).

[0057] The operator holds the sphere 28, aligns its mouth with the position of the cone head 10, and moves the sphere 28 toward the centering sleeve 8. The cone head 10 and the elastic sleeve 9 are both extended into the interior of the sphere 28, and the opening of the mouth of the sphere 28 abuts against the middle position of the centering sleeve 8. During this process, the arc box 12 and the sphere 28 are staggered and do not affect the movement of the sphere 28.

[0058] The telescopic end of the electric push rod 26 is controlled to be retracted, and the core rod 4 is driven to move away from the sphere 28 through the support plate 25. The cone head 10 moves synchronously and extends into the interior of the elastic sleeve 9, causing the elastic sleeve 9 to expand. The centering sleeve 8, the elastic sleeve 9, and the cone head 10 cooperate to achieve the positioning of the sphere 28.

[0059] At the same time, the core rod 4 pulls the first rocker arm 19 through the second rocker arm 21, and the end of the first rocker arm 19 close to the second rocker arm 21 swings downward, while the other end of the first rocker arm 19 can drive the arc box 12 to swing upward, so that the arc box 12 and the arc bar 13 swing to the bottom position of the sphere 28, and there is a glue coating gap between the arc bar 13 and the outer wall of the sphere 28.

[0060] The positioning of the sphere 28 and the swinging of the arc box 12 are completed synchronously.

[0061] Next, glue is applied to the sphere 28 from top to bottom by the glue applying head 3 . The glue drips onto the top of the sphere 28 and flows around along the outer wall of the sphere 28 .

[0062] Start the motor 22, and the motor 22 drives the first gear 23 to rotate. Since the first gear 23 is meshed with the second gear 24, the second gear 24 drives the core rod 4 to rotate. With the cooperation of the slide groove 6 and the slider 7, the core rod 4 and the outer sleeve 5 rotate synchronously, and the sphere 28 rotates. During this process, the arc strip 13 pushes and scrapes the glue, so that the glue is evenly applied on the outer wall of the sphere 28, and the excess glue is pushed and scraped by the arc strip 13 and collected on the arc surface of the arc box 12.

[0063] The gluing head 3 can also apply glue multiple times, which can be adjusted according to specific usage conditions.

[0064] After applying the glue, the operator can perform operations such as pasting colored paper.

[0065] When the ball 28 needs to be removed, the telescopic end of the electric push rod 26 is controlled to extend, and the core rod 4 is driven to move toward the ball 28 through the support plate 25. The cone head 10 is withdrawn from the inside of the elastic sleeve 9, causing the elastic sleeve 9 to contract and release the positioning of the ball 28; at the same time, the core rod 4 lifts the first swing rod 19 through the second fixed ring 20 and the second swing rod 21. The end of the first swing rod 19 close to the second swing rod 21 swings upward, and the other end of the first swing rod 19 can drive the arc box 12 to swing downward, so that the arc box 12 and the ball 28 are staggered (refer to Figure 11 ), does not affect the operator to remove the ball 28.

[0066] The present invention realizes uniform rotational gluing by providing structures such as a cone head 10, an elastic sleeve 9, and an arc box 12. At the same time, the structural characteristics of the sphere 28 are utilized for rapid positioning. The positioning of the sphere 28 is linked to the position of the arc box 12, which does not affect the loading and unloading of the sphere 28, thereby improving the utilization efficiency of the uniform gluing rotation device.

[0067] By setting up the first swing rod 19, the second swing rod 21 and other structures, the core rod 4 is used to drive the cone head 10 to move and position the ball 28 as power, so as to realize the up and down swing of the arc box 12 without the need for additional power equipment, thereby reducing energy consumption.

[0068] In order to collect the glue after scraping, a through hole 14 is opened on the arc surface of the arc box 12, and the through hole 14 is located in the middle of the arc surface of the arc box 12 (refer to Figure 8 、 Figure 9 ), there are multiple through holes 14, the multiple through holes 14 are evenly distributed, and the arc bars 13 are distributed corresponding to the through holes 14, and the arc bars 13 divide the through holes 14 into two parts.

[0069] When the excess glue is pushed and scraped by the arc strip 13 and collected on the arc surface of the arc box 12, the glue will enter the interior of the arc box 12 through the through hole 14, achieving the effect of pushing and collecting, preventing the glue from sliding off at will, and facilitating subsequent recycling.

[0070] At the same time, the arc strip 13 divides the through hole 14 into two parts. No matter whether the sphere 28 rotates forward or reverse, the glue can enter the interior of the arc box 12 through the through hole 14, thereby ensuring collection efficiency.

[0071] In addition, the inner cavity of the arc box 12 has a certain depth, so that the glue will not flow out from any through hole 14 even after the arc box 12 is swung downward.

[0072] The bottom of the arc box 12 is provided with a taking slot, a cover plate, etc. (not shown in the figure). The operator can remove the cover plate and use the taking slot to quickly recycle the collected glue.

[0073] A protrusion 15 is integrally formed on the outer wall of the cap 11. There are multiple protrusions 15, which are evenly distributed around the outer wall of the cap 11. The protrusions 15 abut against the arc strip 13, and the protrusions 15 are small, which will only cause the arc strip 13 to swing slightly, and will not affect the uniform application of glue.

[0074] The connection position between the arc bar 13 and the arc box 12 is located at the arc surface of the arc box 12 away from the first rocker arm 19, so that when the arc bar 13 is squeezed near one end of the first rocker arm 19, it can swing slightly. The arc bar 13 can be made of but not limited to rubber material, has a certain deformation ability, and will not cause wear on the sphere 28.

[0075] Specifically, the cap 11 and the outer sleeve 5 rotate synchronously, and the multiple protrusions 15 abut against the arc strip 13 in turn, causing the arc strip 13 to swing slightly, accelerating the glue scraped from the arc strip 13 to enter the interior of the arc box 12 through the through hole 14.

[0076] Working principle: The operator holds the sphere 28, aligns its mouth with the position of the cone head 10, and moves the sphere 28 toward the centering sleeve 8. The cone head 10 and the elastic sleeve 9 are both extended into the interior of the sphere 28, and the opening of the mouth of the sphere 28 abuts against the middle position of the centering sleeve 8. During this process, the arc box 12 and the sphere 28 are staggered and do not affect the movement of the sphere 28.

[0077] The telescopic end of the electric push rod 26 is controlled to be retracted, and the core rod 4 is driven to move away from the sphere 28 through the support plate 25. The cone head 10 moves synchronously, and the cone head 10 extends into the interior of the elastic sleeve 9, causing the elastic sleeve 9 to expand. The centering sleeve 8, the elastic sleeve 9, and the cone head 10 cooperate to achieve the positioning of the sphere 28; at the same time, the core rod 4 pulls the first swing rod 19 through the second swing rod 21, and the end of the first swing rod 19 close to the second swing rod 21 swings downward, and the other end of the first swing rod 19 can drive the arc box 12 to swing upward, so that the arc box 12 and the arc bar 13 swing to the bottom position of the sphere 28, and there is a glue gap between the arc bar 13 and the outer wall of the sphere 28.

[0078] The glue is applied to the sphere 28 from top to bottom through the glue applying head 3. After the glue drops on the top of the sphere 28, it flows around along the outer wall of the sphere 28. The motor 22 is started to make the core rod 4 and the outer sleeve 5 rotate synchronously, and the sphere 28 rotates. During this process, the arc strip 13 pushes and scrapes the glue, so that the glue is evenly spread on the outer wall of the sphere 28, and the excess glue is pushed and scraped by the arc strip 13 and collected on the curved surface of the arc box 12, and enters the interior of the arc box 12 through the through hole 14, achieving the effect of pushing, scraping and collecting.
