DETAILED DESCRIPTION

[0032] The present invention will be further described below in conjunction with the accompanying drawings.

[0033] Embodiment 1:

[0034] In this embodiment, if Figure 1 The shown device is an automatic candle cotton swab forming device, which comprises a feeding mechanism 2, a core loading mechanism 3, a waxing mechanism 4 and a cooling mechanism 5; the feeding mechanism 2 is used to separate the bamboo core 6 from the material pile, and make the bamboo core 6 pass through the core loading mechanism 3, the waxing mechanism 4 and the cooling mechanism 5 in sequence; the core loading mechanism 3 is used to cover a flexible fabric core on one end of the bamboo core 6; the waxing mechanism 4 is used to cover the flexible fabric core of the bamboo core 6 with wax liquid to form an external dense layer; the cooling mechanism 5 is used to quickly cool the external dense layer on one end of the bamboo core 6. The bamboo core 6 is conveyed to the core loading mechanism 3 by the feeding mechanism 2, and the feeding mechanism 2 conveys the bamboo core 6 into the core loading mechanism 3 one by one at a time, and the core loading mechanism 3 covers the outer surface of one end of the bamboo core 6 with a layer of flexible fabric core; then the feeding mechanism 2 conveys the bamboo core 6 with the flexible fabric core to the waxing mechanism 4, and the bamboo core 6 wraps the surface of the flexible fabric core with a layer of wax liquid in the waxing mechanism 4, and the wax liquid can penetrate into the inside of the flexible fabric core; then the feeding mechanism 2 drives the bamboo core 6 with the outer dense layer into the cooling mechanism, and after the bamboo core 6 passes through the cooling mechanism, its outer dense layer is quickly cooled and shaped, and then the feeding mechanism 2 conveys the bamboo core 6 out of the cooling mechanism 5, and gathers the bamboo core 6 in the receiving device (not shown in the figure) at the outlet end of the cooling mechanism 5. Since the wax liquid has strong adhesion and fast cooling speed, the cooling method can be air cooling, natural cooling or temperature reduction cooling. The present invention can quickly attach the flexible fabric core and the outer dense layer to the bamboo core 6 and quickly cool and shape them, so the entire candle cotton swab production process takes less time and has higher production efficiency. At the same time, the present invention has a high degree of automation, reduces the manual workload in the candle cotton swab molding process, and saves more labor costs.

[0035] In this embodiment, the present invention further comprises a support mechanism 1 (such as Figures 1 to 7 As shown in FIG. 1 , the support mechanism 1 includes a base frame 11, a vertical support frame 12 and a top mounting frame 13 placed sequentially from bottom to top. The core loading mechanism 3, the waxing mechanism 4 and the cooling mechanism 5 are sequentially arranged along the length direction of the base frame 11, and the feeding mechanism 2 is arranged across one side of the core loading mechanism 3, the waxing mechanism 4 and the cooling mechanism 5.

[0036] In this embodiment, the cooling mechanism 5 is an air cooling mechanism, which includes a plurality of fans arranged along the length direction of the feeding mechanism 2. Specifically, the fans are installed on the top mounting frame 13 and are located directly above the outer dense layer of the bamboo core 6. Since the outer dense layer of the bamboo core 6 is wax liquid, the wax liquid can solidify quickly when it is cooled, and the wax liquid will penetrate into the interior of the flexible fabric core. The fan will not damage the outer dense layer when cooling by air, so that the outer dense layer can be quickly cooled and shaped.

[0037] In this embodiment, the material receiving device may be a frame-type container, and the material receiving device may be placed below the end of the transmission chain 25 at the cooling mechanism 5 .

[0038] Embodiment 2:

[0039] This embodiment provides an optional solution for the specific structure of the feeding mechanism based on the first embodiment.

[0040] In this embodiment, if Figures 1 to 6 As shown, the feeding mechanism 2 includes a silo 22, a loading gear 23, a transport gear 24 and a transmission chain 25; a material pile formed by a plurality of bamboo cores 6 placed horizontally and stacked is stacked in the silo 22; the loading gear 23 is arranged at the outlet end of the silo 22, and the height of the axis of the loading gear 23 is lower than the height of the outlet of the silo 22; the transport gear 24 is used to drive the transmission chain 25 to rotate, and the transport gear 24 and the loading gear 23 are arranged alternately; a plurality of limiting elements 251 are arranged on the conveying surface of the transmission chain 25, and a groove body that can only accommodate a single bamboo core 6 is formed between two adjacent limiting elements 251.

[0041] Specifically, the feeding mechanism 2 also includes a mounting groove 21, and the rotating shaft of the feeding gear 23 is installed across the mounting groove 21, and at least one end of the rotating shaft of the feeding gear 23 passes through the side wall of the mounting groove 21 and is connected to the driving motor, so that the feeding gear 23 is driven to rotate by the driving motor. At the same time, multiple groups of feeding gears 23 can be set according to actual conditions. Each group of feeding gears 23 includes at least two identical gears arranged coaxially, and the two identical gears are arranged on one side of the mounting groove 21, so that the two gears of the feeding gear 23 simultaneously hold up the end of the bamboo core 6 that does not need to be waxed, and the two force points hold up the bamboo core 6, which can effectively prevent the bamboo core 6 from tilting or falling during feeding.

[0042] In this embodiment, the installation groove 21 is arranged at one end of the basic frame 11, the transport gear 24 and the conveyor chain 25 are located on one side of the width direction of the basic frame 11, and a group of transport gears 24 are also arranged at the end of the basic frame 11 away from the installation groove 21. The transmission chain 25 is connected to the transport wheels 24 at both ends of the basic frame 11, thereby realizing the transportation of the bamboo core 6 from the silo 22 to the end where the cooling mechanism 5 is located.

[0043] In this embodiment, two parallel transmission chains 25 are arranged on the basic frame 11. The two transmission chains 25 jointly support one end of the bamboo core 6 and drive one end of the bamboo core 6 to move, so that the other end of the bamboo core 6 passes through the core-applying mechanism 3, the wax-applying mechanism 4 and the cooling mechanism 5 in sequence.

[0044] In this embodiment, the silo 22 is arranged at the top of one end of the installation groove 21, and the bottom plate of the silo 22 is arc-shaped, and the bamboo core 6 is stacked in the silo 22 along the width direction of the installation groove 21. The bamboo core 6 is automatically accumulated to the low point of the silo 22 under the action of gravity. The height of the axis of the feeding gear 23 is lower than the height of the outlet of the silo 22 (such as Figure 3 As shown in the figure, when the feeding gear 23 rotates, the part of the tooth profile of the feeding gear 23 located in the silo 22 will lift upward and drive the bamboo core 6 to leave the silo 22.

[0045] In this embodiment, if Figure 2 As shown, there are two groups of feeding gears 23, the two groups of feeding gears 23 are staggered and the tooth profiles partially overlap, and the transport gear 24 is staggered and the tooth profiles partially overlap with the nearest feeding gear 23. When feeding, the feeding gear 23 at the end of the silo 22 rotates counterclockwise, so that the bamboo core 6 in the silo 22 is lifted by the tooth groove of the feeding gear 23, and when it rotates to the part overlapping with the other group of feeding gears 23, the other feeding gear 23 transfers the bamboo core 5 to the transmission chain 25 on the transport gear 24, so that the bamboo core 6 enters the groove formed between two adjacent limiting elements 251 on the transmission chain 25.

[0046] In this embodiment, the space of the tooth groove of the feeding gear 23 and the groove formed by two adjacent limiting elements 251 on the transmission chain 25 can only accommodate a single bamboo core 6 (such as Figure 6 As shown). This can effectively prevent a plurality of bamboo cores 6 from being transported at a time, thereby preventing a single bamboo core 6 from entering the core-loading mechanism 3 and the waxing mechanism 4, and can effectively ensure that the flexible fabric layer on the bamboo core 6 and the outer dense layer are completely and evenly covered.

[0047] In this embodiment, in order to prevent the bamboo core 6 from being stuck and breaking when two adjacent groups of feeding gears 23 transfer the bamboo core 6, the edges of the teeth of the feeding gear 23 and the limiting element 251 of the transmission chain 25 that contact the bamboo core 6 should be chamfered.

[0048] In this embodiment, if Figures 4 to 6 As shown, a friction transmission rod 26 is arranged parallel to the transmission surface of the transmission chain 25, and a flexible contact layer 261 is arranged at the bottom of the friction transmission rod 26. The flexible contact layer 261 is used to contact and drive the bamboo core 6 to rotate.

[0049] Specifically, the friction transmission rod 26 is installed under the top-level mounting frame 13, and the distance between the flexible contact layer 261 and the transmission chain 25 is smaller than the diameter of a single bamboo core 6, so that the bamboo core 6 will be in close contact with the flexible contact layer 261 after entering under the friction transmission rod 26, thereby generating friction. As the transmission chain 25 continues to drive the bamboo core 6 for linear transmission, the friction of the flexible contact layer 261 causes the bamboo core 6 to roll on the transmission chain 25, so that the other end of the bamboo core 6 can be covered more evenly with the flexible fabric layer in the core-applying mechanism 3, and the bamboo core 6 can be more evenly coated with the wax liquid in the dense layer inside and outside the waxing mechanism 4, and at the same time, the bamboo core 6 can be cooled more evenly in the cooling mechanism 5 and the cooling speed is faster.

[0050] In this embodiment, the end of the friction transmission rod 26 should be provided with a guiding structure, such as a rounded corner or a wedge-shaped surface, so that the bamboo core 6 can normally enter under the flexible contact layer 261 .

[0051] In this embodiment, the flexible contact layer 261 is made of a material such as silicone or rubber that is softer and more wear-resistant than the bamboo core 6, so that the flexible contact layer 261 can press against the bamboo core 6 by generating elastic deformation, while not hindering the bamboo core 6 from rolling in the groove formed between two adjacent limiting elements 251.

[0052] Embodiment three:

[0053] This embodiment provides an optional solution for the specific structure of the core loading mechanism based on any of the above embodiments.

[0054] In this embodiment, if Figure 4 and Figure 5 As shown, the upper core mechanism 3 includes a fabric crushing element and a negative pressure traction chamber 34, the fabric crushing element is installed directly above the negative pressure traction chamber 34, a first mesh plate 321 is provided at the bottom of the fabric crushing element, and a second mesh plate 341 is provided at the top of the negative pressure traction chamber 34; the fabric crushing element is used to crush the fabric into flocs, and the negative pressure traction chamber 34 is used to form negative pressure and pull the flocculent fabric through the first mesh plate 321 and the second mesh plate 341 into the negative pressure traction chamber 34; the end of the bamboo core 6 away from the transmission chain 25 passes through the gap between the first mesh plate 321 and the second mesh plate 341 and is wrapped with flocculent fabric.

[0055] In this embodiment, the flexible fabric core coated on the surface of the bamboo core 6 is made of cotton. Correspondingly, the fabric crushing element is a cotton crusher, which should at least include a feed port 31, a crushing chamber 32 and a crushing tool 33. The crushing chamber 32 is arranged at one end of the top surface of the base frame 11 close to the mounting groove 21, and the crushing chamber 32 is located on one side of the transmission chain 25. A funnel-shaped feed port 31 is arranged on the top of the crushing chamber 32, and a fabric ball composed of cotton is put into the crushing chamber 32 from the feed port 31. A crushing tool 33 is arranged inside the crushing chamber 32, and the crushing tool 33 crushes the ball-shaped cotton into fine flocs, so that the cotton can pass through the mesh holes on the first mesh plate 321 and the second mesh plate 341.

[0056] It should be noted that cotton crushers and other fabric crushing mechanisms are commercially available products, and their specific structures, working principles, etc. are not described here (the structures of crushing cutters, etc. can be referred to in the invention patent with publication number CN 111545309 A).

[0057] In this embodiment, an air outlet pipe 342 is provided at the bottom of the negative pressure traction chamber 34, and a negative pressure fan (not shown in the figure) is provided at the other end of the air outlet pipe 342. The air pressure fan continuously discharges the air in the negative pressure traction chamber 34 through the air outlet pipe 342, so that the air flow rate in the negative pressure traction chamber 34 is greater than that in the crushing chamber 32, and the air pressure in the negative pressure traction chamber 34 is lower than the air pressure in the crushing chamber 32, so that the flocculent fabric in the crushing chamber 32 is pulled through the first mesh plate 321 and the second mesh plate 341. When one end of the bamboo core 6 passes between the first mesh plate 321 and the second mesh plate 341, the flocculent fabric covers and adheres to the bamboo core 6, and because the bamboo core 6 keeps rotating when moving, the flexible fabric layer can be covered more evenly in the circumference of the bamboo core 6.

[0058] At the same time, in order to ensure that the fabric can be attached to the bamboo core 6, in this embodiment, a wetting mechanism is provided between the feeding mechanism 2 and the core-loading mechanism 3.

[0059] like Figure 4 and Figure 5As shown, the wetting mechanism includes a water inlet pipe 14 and a wet wipe 15 arranged on the top mounting frame 13, and both are located above the transmission chain 25; the top of the wet wipe 15 is fixed, and its bottom end contacts the end of the bamboo core 6 away from the transmission chain 25. When the transmission chain 25 drives the bamboo core 6 to move, the end of the bamboo core 6 away from the transmission chain 25 contacts the wet wipe 15, thereby wetting one end of the bamboo core 6, so that the flocculent fabric in the upper core mechanism 3 can be better attached to the bamboo core 6 when it contacts the bamboo core 6; the water inlet pipe 14 is connected to the external water, and the water replenishment is controlled by the electromagnetic valve. At the same time, since the amount of water required to moisten the bamboo core 6 is not large, the wet wipe 15 can be continuously replenished with water by using a quantitative dripping method. In addition, when one end of the bamboo core 6 enters between the friction transmission rod 26 and the transmission chain 25, the other end of the bamboo core 6 will contact the wet wipe 15.

[0060] Embodiment 4:

[0061] This embodiment provides an optional solution for the specific structure of the waxing mechanism based on any of the above embodiments.

[0062] In this embodiment, if Figures 1 to 11 As shown, the waxing mechanism 4 includes a wax liquid supporting plate 41 and a pressure plate 42; a wax inlet pipe 411 and a wax accumulation groove 413 are provided on the top surface of the wax liquid supporting plate 41, and the wax inlet pipe 411 is used to input wax liquid into the wax accumulation groove 413; the pressure plate 42 is movably installed above the wax accumulation groove 413, and the pressure plate 42 is used to press down one end of the bamboo core 6 so that the flexible fabric core of the bamboo core 6 enters the wax accumulation groove 413 and is wrapped with wax liquid.

[0063] Specifically, the wax inlet pipe 411 is arranged on a side of the wax liquid support plate 41 close to the upper core mechanism 3, and a plurality of wax outlets 412 are provided on the wax inlet pipe 411, and the plurality of wax outlets 412 are evenly arranged in the length direction of the wax accumulation tank 413. The inlet end of the wax inlet pipe 411 is connected to a liquid pump (not shown in the figure), and the liquid pump is used to transport liquid wax to the wax accumulation tank 413.

[0064] In this embodiment, the wax liquid support plate 41 is also connected to a wax drain pipe 43, which is used to collect the wax liquid flowing out of the wax liquid support plate 41 and discharge it. The wax drain pipe 43 is a semicircular tube, and its top surface is flush with the bottom surface of the wax accumulation groove 413, so that the wax liquid in the wax accumulation groove 413 can flow normally into the wax drain pipe 43, so that the wax liquid can be collected by the wax drain pipe 43 and guided to the liquid pump for recycling.

[0065] In other embodiments, the wax drain pipe 43 can be a complete round tube with a notch on one side close to the wax accumulation groove 413 so that the inside of the wax drain pipe 43 is connected to the wax accumulation groove 413. Compared with a semi-circular tube, a round tube can avoid the problem of excessive wax liquid overflow.

[0066] In this embodiment, if Figures 8 to 11As shown, the plate body of the pressure plate 42 is arc-shaped, and a mounting shaft 421 is provided on one side of the pressure plate 42 close to the upper core mechanism 3, and both ends of the mounting shaft 421 are rotatably mounted in the mounting arm 422. The top end of the mounting arm 422 is mounted on the top mounting frame 13, and the bottom end of the mounting arm 422 is hingedly connected to the mounting shaft 421, so that the pressure plate 42 can rotate around the mounting shaft 421.

[0067] At the same time, the protruding portion of the bottom surface of the pressure plate 42 sinks into the wax accumulation groove 413, so that the bottom of the pressure plate 42 is also stained with wax liquid. When the end of the bamboo core 6 with the flexible fabric core is transmitted to the position of the pressure plate 42 by the transmission chain 25, the bamboo core 6 is slightly deformed and bent at the end away from the transmission chain 25 under the action of the gravity of the pressure plate 42 and the guiding action of the arc-shaped bottom surface, so that the flexible fabric core of the bamboo core 6 can be immersed in the wax liquid in the wax accumulation groove 413, and the bamboo core 6 will rotate under the simultaneous action of the friction transmission rod 26 and the transmission chain 25, so that the surface of the flexible fabric core on the bamboo core 6 can be fully in contact with the wax liquid, so that the waxing is more uniform; and because the mounting shaft 421 of the pressure plate 42 can rotate, the pressure plate 42 can rotate around the mounting shaft 421 when the bamboo core 6 passes its bottom end, thereby preventing the bamboo core 6 from breaking.

[0068] In this embodiment, a first heating element 414 is provided on the bottom surface of the wax liquid support plate 41; a second heating element 423 is provided on the pressure plate 42. The first heating element 414 keeps the wax liquid in the wax accumulation groove 413 always in liquid state by heating and does not solidify. At the same time, the pressure plate 42 is provided with a second heating element 423. The second heating element 423 can prevent the wax liquid from solidifying and adhering to the pressure plate 42.

[0069] In this embodiment, the first heating element 414 and the second heating element 423 are both metal blocks with mounting holes. The mounting holes of the metal blocks are used to install electric heating tubes. The metal blocks are welded to the bottom of the wax liquid support plate 41 and the top of the pressure plate 42.

[0070] Since the bamboo core 6 is usually a long bamboo product, in order to prevent the bamboo core 6 from being broken due to the inability to support the pressure plate 42 when passing through the wax accumulation groove 413, the size and material of the pressure plate 42 and the second heating element 423 should be appropriately selected; at the same time, a bearing can also be provided at the connection between the mounting shaft 421 and the mounting arm 422, so that the rotation of the pressure plate 42 is more sensitive.

[0071] It should be noted that, in the present invention, the material of the bamboo core 6 is not limited to bamboo products, and other conventional replacements should also be within the protection scope of the present invention.
