Description

Technical Field

[0002] Due to the wide variety of wine bottle caps, the changes in the structure of wine bottle caps are mainly for anti-counterfeiting and decorative purposes. Among them, anti-counterfeiting wine bottle caps are generally made of multiple parts, including an upper cover, a lower cover and a buckle top. During the separate production process, the outer surface needs to be sprayed with paint. In the spraying production process, the wine bottle caps are conveyed to the spraying room through the outflow line for spraying. Before and after spraying or during the transportation process, they are placed on a shelf, waiting for subsequent processes, or transported to other places. During spraying, the wine bottle caps need to be positioned by a fixture, and after positioning, they are sent to the spraying room for spraying, gold plating, drying and other processes before component assembly, thereby completing the processing of the wine bottle caps.

[0003] At present, general anti-counterfeit wine bottle caps are processed separately during the production process, that is, each assembly component of the wine bottle cap is produced separately, painted independently, and then the finished product is assembled. When spraying the wine bottle caps, different clamps are required when spraying the individual components. This leads to the need for more clamps, and the interoperability between different clamps is low, and the production cost is high. At the same time, after the separately produced wine bottle cap components are painted, there is a color difference between different components, which leads to insufficient aesthetics and affects the overall coordination.

[0030] The following is combined with Figure 1-7 , an embodiment of a clamping and conveying device for producing wine bottle caps by spraying paint of the present invention is further described in detail.

[0031] A clamping and conveying device for the production of wine bottle caps spray paint, such as Figure 1 and Figure 7 As shown, it includes an assembly line 1, a marble clamp 2 arranged on the assembly line 1, and a spinning mechanism 3 for driving the marble clamp 2 to rotate. The marble clamp 2 includes a clamping part 21 for clamping and fixing a wine bottle cap and a connecting part 22 for driving the clamping part 21 to rotate. The clamping part 21 is stacked with a chassis 211, a transition plate 212 connected to the chassis 211, a carrier basin 213 arranged on the transition plate 212, and a clamping plate 214 connected to the carrier basin 213 in sequence from bottom to top. The chassis 211, The transition plate 212, the carrier basin 213 and the clamping plate 214 are all annular structures with openings at both ends and a hollow inner cavity. A plurality of perforations 2141 are distributed circumferentially on the clamping plate 214. The plurality of perforations 2141 are connected to the inner cavity of the clamping plate 214, and an elastic locking assembly 4 is also connected between the perforations 2141 and the inner cavity; one end of the connecting portion 22 extends into the cavity of the clamping basin, and the other end is fixed on the assembly line 1, and the connecting portion 22 is rotatably connected to the spinning mechanism 3 to drive the marble clamp 2 to rotate together.

[0032] Specifically, when processing the wine bottle cap, it is desired to assemble the wine bottle cap components of various parts into a complete anti-counterfeit wine bottle cap, and then use the external material taking device to press the wine bottle cap down to the marble clamp 2 in sequence. During the pressing process, the upper cover body of the wine bottle cap will be attached to the outer side of the clamping plate 214, and its lower cover body will be limited under the action of the bottom plate 211, and ensure that its lower cover body is attached to the outer side of the transition plate 212 and the carrier basin 213. When fixing the wine bottle cap, the marble clamp 2 uses the elastic locking assembly 4 to lock the pressed wine bottle cap to avoid displacement during painting and affect the painting effect; then the elastic clamp is transported through the assembly line 1 to the painting station. During the painting process, the spin mechanism 3 drives the marble clamp 2 to rotate through the rotating belt 31, so that the paint can be evenly covered on the entire outer surface of the wine bottle cap, thereby effectively improving the painting effect of the wine bottle cap, and can also avoid the problem of color difference when a single bottle cap component is sprayed.

[0033] In this embodiment, if Figure 5As shown, the elastic locking assembly includes a reset spring 41, a marble 42, a locking rod 43 and a locking sleeve 44. The marble 42 is circumferentially distributed in the inner cavity of the clamping disk 214, and part of the sphere of the marble 42 protrudes from the through hole 2141. The marble 42 and the through hole 2141 are clearance-fitted, and another part of the sphere of the marble 42 is located in the inner cavity and abuts against the reset spring 41; the reset spring 41 is transversely sleeved on the outside of the locking rod 43, and one end of the reset spring 41 is fixed on the locking rod 43; one end of the locking rod 43 is fixedly connected to the locking sleeve 44, and the locking sleeve 44 is sleeved on one end extending from the connecting part 22.

[0034] Specifically, when the assembled wine bottle caps are sprayed with paint, the wine bottle caps to be sprayed with paint are inserted into the bottom plate 211 from the upper end of the clamping basin. During the sleeve connection process, the elastic locking component can perform elastic contraction, so that the marble clamp 2 can adapt to the bottle caps with diameters within a certain range, and can also enhance the clamping force of the marble 42 on the wine bottle caps after the return spring 41 rebounds, so as to prevent the wine bottle caps from being thrown out due to excessive rotation speed; the locking rod 43 and the marble 42 are both made of magnetic material, that is, one end of the locking rod 43 can be magnetically connected with the marble 42, and in a natural state, due to the action of the return spring 41, the marble 42 and the locking A certain distance is maintained between the rods 43 to avoid an attraction reaction; in addition, in the process of removing the wine bottle cap, the wine bottle cap mounted on the outside of the marble clamp 2 is sucked by an external material taking mechanism that is compatible with the wine bottle cap, and in the process of the wine bottle cap being separated from the marble clamp 2, the wine bottle cap is pressed downward again, so that the elastic locking assembly is subjected to pressure, the marble 42 moves inward, the elastic return spring 41 is compressed under the extrusion, the locking rod 43 contacts the marble 42 and is attracted to it under the action of magnetism, so that the marble 42 is separated from the wine bottle cap and contacts the restriction on the wine bottle cap, so that the wine bottle cap can be easily removed and the subsequent processing steps can be completed.

[0035] In this embodiment, if Figure 6 As shown, the connecting part 22 includes a rotating shaft 221, a threaded sleeve 222 and a threaded connecting rod 223. One end of the rotating shaft 221 passes through the chassis 211, the transition plate 212 and the carrier basin 213 and extends into the clamping plate 214. The other end is rotatably connected to the threaded sleeve 222. The threaded sleeve 222 is rotatably connected to the rotating shaft 221 and the threaded connection, and a bearing 225 is rotatably connected to the mounting seat 224; the threaded connecting rod 223 is a stepped shaft structure, and the bottom end of the threaded connecting rod 223 is set as a threaded joint 2231.

[0036] Specifically, the connecting part 22 is a medium connecting the clamping part 21 and the assembly line 1, wherein the rotating shaft 221 is used as a transmission part, and one end of the rotating shaft 221 is connected to the threaded sleeve 222. The other end extends into the clamping part 21, so that when the spinning mechanism 3 rotates, the rotational force is transmitted to the rotating shaft 221 through the threaded sleeve 222, and then the rotating shaft 221 drives the clamping part 21 to rotate; in addition, in order to clamp and fix the marble 42 on the assembly line 1, the threaded connecting rod is fixedly connected to the assembly line 1, so that the marble clamp 2 is transported to different stations under the transmission of the assembly line 1 to complete the processing.

[0037] In this embodiment, the threaded sleeve 222 is sleeved on the outer side of the bearing 225 mounting seat 224 , and the bearing 225 is sleeved on one end of the bearing 225 mounting seat 224 close to the rotating shaft 221 .

[0038] Specifically, the purpose of setting the threaded sleeve 222 is to better transmit the information. When the spinning mechanism 3 drives the marble clamp 2 to rotate, the threaded sleeve 222 is used as the transmission medium. The threaded structure can better increase the friction, making the transmission process more stable and smooth. At the same time, in order to drive the rotating shaft 221 to rotate, a bearing 225 is set at one end of the bearing 225 mounting seat 224, so that the rotating shaft 221 can synchronously follow the threaded sleeve 222 to rotate together, thereby driving the clamping part 21 to rotate, so as to facilitate the wine bottle cap to be evenly sprayed with paint.

[0039] In this embodiment, if Figure 7 As shown, an end of the clamping disk 214 that is open to the outside is provided with an internal thread interface, and a cover plate 215 is threadedly connected to the internal thread interface.

[0040] Specifically, during the painting process, due to the presence of holes on the top of some wine bottle caps, the paint is easily splashed onto the clamping plate 214. In order to avoid this problem, a covering plate 215 is threadedly connected to the top of the clamping plate 214, so that the clamping basin is in a relatively sealed state, and the covering plate 215 can be opened during maintenance or other work to detect the situation inside the clamping cavity.

[0041] In this embodiment, the diameter of the bottom plate 211 is greater than the diameter of the transition plate 212, and a portion of the bottom plate 211 is wrapped around the outer surface of the transition plate 212 to form a limiting portion for limiting and fixing the wine bottle cap.

[0042] Specifically, the function of the chassis 211 is, on the one hand, to seal the bottom of the clamping part 21, and on the other hand, to limit the position of the wine bottle cap, so that when it is installed on the clamping part 21, the part of the chassis 211 protruding and wrapped in the transition plate 212 is in contact with the wine bottle cap, forming a limiting part for limiting the wine bottle cap. When the wine bottle cap is sleeved on the outside of the clamping part 21, its bottom is just in contact with the top of the chassis 211, which is convenient for the rapid positioning and installation of the wine bottle cap.

[0043] In this embodiment, grooves 2111 are symmetrically provided on the outer surfaces of the bottom plate 211 and the transition plate 212, and the depth of the grooves 2111 is 5-10 mm. The purpose of providing the grooves 2111 is to fit the outer structure of the bottle cap so that when it is installed on the marble clamp 2, it can perfectly fit the clamping part 21.

[0044] In this embodiment, a threaded hole 2112 is further provided on one side of the chassis 211 , a through hole 2211 is provided at a position of the rotating shaft 221 corresponding to the threaded hole 2112 , and the chassis 211 is fixed to the rotating shaft 221 by adjusting screws penetrating the threaded hole 2112 and the through hole 2211 .

[0045] Specifically, in order to better fix the clamping part 21 on the connecting part 22, a threaded hole 2112 is set on the chassis 211, and a through hole 2211 is opened at the corresponding position of the rotating shaft 221, and the adjusting screw is passed through the threaded hole 2112 and the through hole 2211, so that the chassis 211 can be stably connected to the rotating shaft 221, and the clamping part 21 is driven to rotate together when the rotating shaft 221 rotates.

[0046] In this embodiment, if Figure 4 As shown, the assembly line 1 is provided with a plurality of bases 11 for connecting the marble clamps 2. The plurality of bases 11 are fixedly connected to the assembly line 1, and the bases 11 are provided with connecting holes with internal threads. The marble clamps 2 are threadedly connected to the connecting holes through threaded joints 2231.

[0047] Specifically, Figure 2As shown, the assembly line 1 includes a chain and a driving motor for driving the chain to rotate. Through the operation of the conveyor chain of the assembly line 1, the product is moved to each production operation point to complete different production links. However, when the chain is in a cyclic operation, it will gradually relax and lengthen, thereby affecting the smooth progress of the conveying link, and even derailment, resulting in the inability to carry out normal production; for this reason, the present invention provides a tensioning adjustment mechanism on the chain, so that the chain can be automatically tensioned during use, thereby ensuring smooth production; wherein, the tensioning adjustment mechanism includes a box, a tension spring and a screw rod, one end of the tension spring is connected to the screw rod, and the tension spring is in a tensioned state, and the other end of the screw rod passes through the nut provided in the box and extends out of the box, which is used to adjust the tension of the tension spring; by providing the screw rod, the tension of the tension spring can be adjusted, thereby ensuring that the tension spring can always have the function of automatically tensioning the chain.

[0048] It is worth mentioning that in order to ensure that the marble clamp 2 can be stably transmitted through the assembly line 1, a base 11 is set at the bottom end of the elastic clamp, and the base 11 is equidistantly fixed on the chain of the assembly line 1. The threaded joint 2231 at the bottom end of the elastic clamp is threadedly connected to the threaded connection hole 111 on the base 11, so that the marble clamp 2 can be replaced according to the type of bottle cap. The marble clamp 2 that is compatible with it can improve the applicability of the assembly line 1.

[0049] In this embodiment, if Figure 3 , 4 As shown, the spinning mechanism 3 includes a rotating belt 31, a reduction motor 32, a transmission wheel assembly 33 and a plurality of tension wheels 34. The belt surface of the rotating belt 31 abuts against the side surface of the threaded sleeve 222, and the rotating belt 31 is sleeved on the outer surfaces of the transmission wheel assembly 33 and the tension wheel 34; the reduction motor 32 is transmission-connected to the transmission wheel assembly 33.

[0050] Specifically, the transmission wheel assembly 33 includes a driving wheel and a driven wheel, and the tensioning wheel 34 is arranged between the driving wheel and the driven wheel, and at least two tensioning wheels 34 move the rotating belt 31 in the direction away from the axial line connecting the driving wheel and the driven wheel. For example, the tensioning wheel 34 close to the side of the assembly line 1 is arranged at a position away from the axial line connecting the driving wheel and the driven wheel. Therefore, the rotating belt 31 can be closer to the threaded sleeve 222 of the marble clamp 2, thereby increasing the friction between the two, better driving the rotating shaft 221 to rotate, and preventing the driving wheel and the driven wheel from contacting the marble clamp 2.

[0051] In order to make the belt surface of the rotating belt 31 vertical, the axes of the driving wheel, the driven wheel and the tensioning wheel 34 in the present invention are vertically arranged, and the rotating belt 31 is sleeved on the driving wheel, the driven wheel and the tensioning wheel 34. Although it will be tensioned during use, the rotating belt 31 will still slide down under the action of gravity. In this regard, in a preferred embodiment, the outer peripheral sides of the driving wheel, the driven wheel and the tensioning wheel 34 are provided with an upper edge and a lower edge, and an annular groove for accommodating the rotating belt 31 is formed between the upper edge and the lower edge. The groove pitch of the annular groove is equal to or slightly larger than the bandwidth of the rotating belt 31, and the groove depth is smaller than the thickness of the rotating belt 31. Therefore, when the rotating belt 31 is sleeved on the outside of the driving wheel, the driven wheel and the tensioning wheel 34, the upper edge and the lower edge will not slip off the wheel due to the action of the upper edge and the lower edge. Moreover, since the groove depth of the annular groove is smaller than the thickness of the rotating belt 31, when the rotating belt 31 is in close contact with the marble clamp 2, the upper edge and the lower edge will not contact the marble clamp 2.

[0052] Working principle of the present invention:

[0053] Before spraying paint on the anti-counterfeit wine bottle cap, the different parts of the cover body are first assembled into a completed wine bottle cap, and then a single wine bottle cap is pressed onto the marble clamp 2 at a time through the unloading device. During the pressing process, the upper cover body of the wine bottle cap will fit the outer surface of the clamping plate 214, and its lower cover body is limited under the action of the bottom plate 211, and ensures that its lower cover body fits the outer side surface of the transition plate 212 and the carrier basin 213. When fixing the wine bottle cap, the marble clamp 2 uses the elastic locking component 4 to lock the pressed wine bottle cap to avoid displacement during painting and affecting the painting effect; then the elastic clamp is transported through the assembly line 1 to the painting station. During the painting process, the spin mechanism 3 drives the marble clamp 2 to rotate through the rotating belt 31, so that the paint can be evenly covered on the entire outer surface of the wine bottle cap, thereby effectively improving the painting effect of the wine bottle cap and avoiding the problem of color difference when a single bottle cap component is sprayed.

[0054] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
