Description

Technical Field

[0001] This utility model belongs to the field of plastic flower processing technology and relates to an automatic coloring device for plastic flowers. Background Technology

[0002] Plastic flowers are artificial flowers made primarily of plastic. Due to their vibrant colors, diverse shapes, and long shelf life, they are widely used in home decoration and commercial spaces. In the production of plastic flowers, coloring is necessary to enhance their realism and aesthetic appeal.

[0003] Patent document CN110743746A discloses an automatic coloring device for plastic flowers, including a base, a storage cylinder, a conveying pump, and an atomizing spray disc. Two sets of drive rollers are symmetrically installed on both sides of the top of the base, and a conveyor belt connects the two sets of drive rollers. Employing a fully automatic coloring and drying structure, it can automate the powder coating and drying process of plastic flowers, reducing the workload of operators and improving the efficiency and quality of the coloring process. Furthermore, the internal rotary conveyor structure can drive the plastic flowers to rotate at a uniform speed while conveying them, facilitating even coloring and drying, thus improving the quality of the coloring and drying process. However, this device has the following drawback: after the dried plastic flowers slide out from the right side of the machine cover under the conveyor belt, manual removal of the colored and dried plastic flowers is required. This is not conducive to saving manpower or improving coloring efficiency.

[0004] To address the aforementioned problems, this utility model proposes an automatic coloring device for plastic flowers. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model proposes an automatic coloring device for plastic flowers.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automatic coloring device for plastic flowers, comprising a base, a spraying assembly, and a clamping assembly; the spraying assembly is disposed above the base, a conveyor belt is disposed on the base, support seats are fixedly and rotatably mounted on the conveyor belt along the conveying direction, mounting blocks are rotatably mounted on the support seats, toothed rings are rotatably mounted on the mounting blocks, a first toothed bar that cooperates with the toothed ring is disposed on the upper side of the base, a second toothed bar that cooperates with the toothed ring is disposed on the lower side of the base, a clamping assembly for clamping and fixing the plastic flower is disposed on the mounting block, and two wedge-shaped blocks that drive the clamping assembly to move closer to the plastic flower are fixedly connected to the inner ring of the toothed ring, the two wedge-shaped blocks being symmetrically arranged.

[0007] Furthermore, a limiting groove is provided on the mounting block, and a limiting slider is slidably disposed in the limiting groove, the limiting slider being fixedly connected to the toothed ring.

[0008] Furthermore, the mounting block is provided with a limiting component for limiting the limiting slider, and the limiting slider is provided with a positioning groove that cooperates with the limiting component.

[0009] Furthermore, the limiting component includes a second spring and a positioning rod. A groove is provided on the mounting block, and the lower end of the positioning rod is slidably disposed in the groove. The second spring is fixedly connected between the positioning rod and the bottom wall of the groove, and the upper end of the positioning rod is arc-shaped.

[0010] Furthermore, the clamping assembly includes two symmetrically arranged support blocks, which are elastically slidably connected to the mounting block.

[0011] Furthermore, a clamping block is connected to the side of the support block near the axis of the mounting block.

[0012] Furthermore, the mounting block has a mounting groove, a guide rod is fixedly installed in the mounting groove, the lower end of the support block is slidably sleeved on the guide rod, and a first spring is provided between the support block and the mounting block, the first spring being sleeved on the guide rod.

[0013] Furthermore, the clamping assembly includes two symmetrically arranged elastic blocks, which are fixed to the mounting block.

[0014] Furthermore, a clamping block is connected to the side of the elastic block near the axis of the mounting block.

[0015] Furthermore, a collection box is provided on the lower side of the base at a position corresponding to the second toothed rod.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The engagement of the toothed ring and the first toothed rod allows the toothed ring to rotate relative to the mounting block, which in turn causes the wedge-shaped block to press against the clamping assembly, thus clamping and fixing the plastic flower. Then, under the action of the first toothed rod, the toothed ring, mounting block, and plastic flower rotate synchronously, which helps to ensure more uniform coloring and drying of the plastic flower, improving both the coloring and drying quality.

[0017] After the plastic flower is colored and dried, the toothed ring moves to the underside of the conveyor belt and meshes with the second toothed bar. The rotation of the toothed ring relative to the mounting block causes the wedge block to release its pressure on the clamping component, which then releases its grip on the plastic flower, allowing the plastic flower to fall automatically into the collection box. This eliminates the need for manual removal of the plastic flower, saving manpower and improving the automation level and efficiency of plastic flower coloring. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: As Figures 1-10 As shown, the technical solution adopted by this utility model is as follows: an automatic coloring device for plastic flowers, including a base 1, a spraying component 11 and a clamping component.

[0022] A conveyor belt 3 is installed on the base 1, which is used to move the plastic flower 5. Specifically, rotating rollers are rotatably installed at both ends of the base 1, and the conveyor belt 3 is wound between the two rotating rollers. A motor 10 is installed at one end of the base 1, and the motor 10 is driven by the corresponding rotating roller. When the motor 10 starts, the corresponding rotating roller rotates, thereby driving the conveyor belt 3 to move between the two rotating rollers.

[0023] A protective shell 8 is installed on the upper side of the base 1. A spraying assembly 11 and a drying assembly 12 are housed inside the protective shell 8. The protective shell 8 is located on the right side of the base 1. Figure 2 As shown, the drying assembly 12 is located to the left of the spraying assembly 11. As the conveyor belt 3 moves, the plastic flower 5 on the conveyor belt 3 passes through the spraying assembly 11, where the spraying assembly 11 sprays and colors the plastic flower 5. Afterward, as the plastic flower 5 passes through the drying assembly 12, the drying assembly 12 dries the colored plastic flower 5.

[0024] A paint tank 7 is installed on the protective shell 8. The paint tank 7 contains paint and is connected to the spraying assembly 11. The paint in the paint tank 7 is sprayed out by the spraying assembly 11 to color the plastic flower 5.

[0025] A fan 9 is installed on the protective shell 8, and the fan 9 is connected to the spraying assembly 11. Under the action of the fan 9, the drying assembly 12 blows air onto the plastic flower 5 to dry the plastic flower 5.

[0026] Both the spraying component 11 and the air drying component 12 are existing technologies and will not be described in detail here.

[0027] Multiple support seats 15 are fixedly installed at intervals along the conveying direction of the conveyor belt 3, and a mounting block 13 is rotatably mounted on each support seat 15. There is a certain rotational damping between the support seat 15 and the mounting block 13. A toothed ring 4 is rotatably mounted on the mounting block 13. The mounting block 13 and the toothed ring 4 are coaxially arranged.

[0028] Two limiting grooves 23 are symmetrically provided on the mounting block 13. The limiting grooves 23 are arc-shaped and coaxial with the mounting block 13. A limiting slider 22 is provided in the limiting groove 23 for limiting sliding. The limiting slider 22 is fixedly connected to the toothed ring 4.

[0029] The mounting block 13 is equipped with a limiting component 19 for limiting the slider 22. The slider 22 has a positioning groove that mates with the limiting component 19. Specifically, the limiting component 19 includes a second spring and a positioning rod. The mounting block 13 has a groove, and the positioning rod is slidably disposed in the groove. The second spring is fixedly connected between the positioning rod and the bottom wall of the groove. The upper end of the positioning rod is arc-shaped. The upper end of the positioning rod mates with the positioning groove. When the slider 22 moves to one end of the limiting groove 23, under the action of the second spring, the positioning rod extends into the positioning groove, thereby limiting the slider 22.

[0030] like Figure 6 As shown, the inner ring of the toothed ring 4 is fixedly connected to two wedge blocks 16, which are symmetrically arranged.

[0031] The mounting block 13 is equipped with a clamping assembly for holding and fixing the plastic flower 5. The clamping assembly is located on the inner ring of the toothed ring 4. The clamping assembly includes two support blocks 18, which are symmetrically arranged about the axis of the toothed ring 4. The support blocks 18 are elastically slidably connected to the mounting block 13. Specifically, the mounting block 13 has a mounting groove, and a guide rod 20 is fixedly installed in the mounting groove. The lower end of the support block 18 is slidably sleeved on the guide rod 20. A first spring 21 is fixedly connected to the support block 18. The end of the first spring 21 away from the support block 18 is fixedly connected to the mounting block 13, and the first spring 21 is sleeved on the guide rod 20.

[0032] Each support block 18 is fixedly connected to a clamping block 17 on the side closest to the axis of the toothed ring 4.

[0033] Place the plastic flower 5 between the two clamping blocks 17, causing the toothed ring 4 to rotate relative to the mounting block 13. The limiting slider 22 slides within the limiting groove 23. The toothed ring 4 drives the wedge block 16 to rotate. The thicker end of the wedge block 16 gradually approaches the support block 18. The wedge block 16 presses against the support block 18, causing the support block 18 to gradually overcome the elastic force of the first spring 21 and move towards the plastic flower 5, thereby clamping and fixing the plastic flower 5.

[0034] A first toothed rod 6, which meshes with the toothed ring 4, is fixedly installed on the upper side of the base 1 along the conveying direction of the conveyor belt 3. As the conveyor belt 3 moves, when the toothed ring 4 meshes with the first toothed rod 6, the first toothed rod 6 drives the toothed ring 4 to rotate. Due to the certain rotational damping between the support base 15 and the mounting block 13, initially, the first toothed rod 6 drives the toothed ring 4 to rotate relative to the mounting block 13, and the limiting slider 22 slides along the limiting groove 23, causing the wedge block 16 to press against the clamping assembly, thereby clamping and fixing the plastic flower 5. When the limiting slider 22 moves to the end of the limiting groove 23, since the limiting slider 22 can no longer slide along the limiting groove 23, the toothed ring 4 drives the mounting block 13 to rotate through the limiting slider 22, and the toothed ring 4, the mounting block 13, and the plastic flower 5 rotate synchronously. When the plastic flower 5 passes through the spraying assembly 11, it is beneficial to spray and color the plastic flower 5 evenly.

[0035] like Figure 3 As shown, a second toothed rod 14 that engages with the toothed ring 4 is fixedly installed on the lower side of the base 1, and a collection box 2 is provided at the corresponding position below the base 1 and the second toothed rod 14. When the toothed ring 4 meshes with the second toothed rod 14, the second toothed rod 14 drives the toothed ring 4 to rotate, causing the wedge block 16 to gradually release its pressure on the clamping assembly, causing the clamping assembly to release its grip on the plastic flower 5, and then causing the plastic flower 5 to fall and fall into the collection box 2.

[0036] Working principle: Initially, the limiting slider 22 is located at the first end of the limiting groove 23, and the wedge block 16 does not contact the support block 18. Under the action of the first spring 21, the support block 18 is on the side of the guide rod 20 away from the axis of the toothed ring 4.

[0037] In use, start the motor 10, causing the upper side of the conveyor belt 3 to move from right to left and the lower side of the conveyor belt 3 to move from left to right. At the right end of the base 1, insert the flower stem of the plastic flower 5 between the two clamping blocks 17. When the toothed ring 4 meshes with the first toothed bar 6, due to the certain rotational damping between the support base 15 and the mounting block 13, the mounting block 13 remains stationary relative to the support base 15, while the toothed ring 4 rotates relative to the mounting block 13, and the limiting slider 22 slides towards the second end of the limiting groove 23. The toothed ring 4 drives the wedge block 16 to move, causing the thicker end of the wedge block 16 to gradually approach the support block 18. The wedge block 16 presses against the support block 18, causing the support block 18 and the clamping blocks 17 to gradually move closer to the flower stem of the plastic flower 5. When the limiting slider 22 moves to the second end of the limiting groove 23, the two clamping blocks 17 clamp and fix the flower stem of the plastic flower 5. At this time, the positioning rod and the positioning groove on the limiting slider 22 are opposite each other. Under the action of the second spring, the positioning rod moves upward and inserts into the positioning groove to limit the limiting slider 22.

[0038] Subsequently, as the conveyor belt 3 moves, the toothed ring 4, driven by the limit slider 22 against the second end of the limit groove 23, causes the mounting block 13 to rotate, making the mounting block 13, toothed ring 4, and plastic flower 5 rotate synchronously. When the plastic flower 5 passes the spraying assembly 11, the spraying assembly 11 sprays and colors the plastic flower 5. Due to the rotation of the plastic flower 5, it is beneficial to evenly color the plastic flower 5.

[0039] When the painted plastic flower 5 passes through the drying assembly 12, the drying assembly 12 dries the plastic flower 5. The rotation of the plastic flower 5 facilitates rapid and even drying.

[0040] After being dried, the plastic flower 5 moves with the conveyor belt 3, causing the toothed ring 4 to disengage from the first toothed bar 6. It then moves to the underside of the conveyor belt 3 and then to the right. Once the toothed ring 4 disengages from the first toothed bar 6, the limiting component 19 prevents the limiting slider 22 from moving unexpectedly, thus preventing the toothed ring 4 from rotating unexpectedly. The clamping component maintains a secure grip on the plastic flower 5, preventing it from falling.

[0041] As the plastic flower 5 moves to the right under the conveyor belt 3, when the toothed ring 4 engages with the second toothed rod 14, the toothed ring 4 rotates relative to the mounting block 13. The limiting slider 22 slides towards the first end of the limiting groove 23, causing the thicker end of the wedge block 16 to gradually move away from the support block 18, thereby gradually releasing the pressure on the support block 18. Under the action of the first spring 21, the support block 18 gradually moves away from the plastic flower 5, thereby gradually releasing the clamping force on the plastic flower 5. After losing the clamping force, the plastic flower 5 falls downward into the collection box 2 under its own gravity.

[0042] Example 2: This example describes the parts that are different from those in Example 1, while the rest are the same as in Example 1.

[0043] like Figure 11 As shown, the clamping assembly includes two elastic blocks 24, which are symmetrically arranged. The lower end of each elastic block 24 is fixedly connected to the mounting block 13. The upper end of each elastic block 24 extends into the toothed ring 4. A clamping block 17 is fixedly connected to the side of each elastic block 24 near the axis of the toothed ring 4.

[0044] When the toothed ring 4 meshes with the first toothed rod 6, the toothed ring 4 rotates relative to the mounting block 13, and the limiting slider 22 slides towards the second end of the limiting groove 23. The toothed ring 4 drives the wedge block 16 to rotate, and the thicker end of the wedge block 16 gradually approaches the elastic block 24. The wedge block 16 gradually squeezes the elastic block 24, and the elastic block 24 produces elastic deformation, causing the clamping block 17 to move closer to the flower stem of the plastic flower 5. When the limiting slider 22 moves to the second end of the limiting groove 23, the two clamping blocks 17 clamp and fix the plastic flower 5.

[0045] When the toothed ring 4 engages with the second toothed rod 14, the toothed ring 4 rotates relative to the mounting block 13. As the limiting slider 22 slides towards the first end of the limiting groove 23, the thicker end of the wedge block 16 gradually moves away from the elastic block 24. The elastic block 24 recovers its deformation under its own elasticity, causing the clamping block 17 to move away from the stem of the plastic flower 5, thereby releasing the clamping and fixing of the plastic flower 5. After losing the clamping and fixing of the clamping block 17, the plastic flower 5 falls downward into the collection box 2.

[0046] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
