[0056] The present invention is further described below in conjunction with the accompanying drawings. It should be noted that the directional words such as up, down, front, back, left, and right referred to in the present invention are all based on Figure 1 The orientation shown in the figure shall prevail.

[0057] like Figures 1 to 18The coin rolling and packaging machine shown comprises: a feeding mechanism 1, a stacking mechanism 2, a supporting fork mechanism 3, a coin supporting mechanism 4, a rubber roller mechanism 5, a paper rolling mechanism 6, a hook knife mechanism 7, a cam mechanism 8, an adjusting mechanism 9 and a feeding channel 10.

[0058] The feeding mechanism 1 is used to sequentially convey the coins to the stacking mechanism 2;

[0059] The stacking mechanism 2 is used for guiding and stacking coins;

[0060] The supporting fork mechanism 3 is used to support the stacked coins in the stacking mechanism 2 in sequence;

[0061] The cam mechanism 8 is used to drive the coin holding mechanism 4 and the hook knife mechanism 7 to work respectively.

[0062] The coin holding mechanism 4 is used to sequentially transfer the stacked coins held by the holding fork mechanism 3 and transport them to the rubber roller mechanism 5;

[0063] The rubber roller mechanism 5 is used to clamp the coin and drive it to rotate;

[0064] The paper rolling mechanism 6 is used to roll the coins;

[0065] The hook knife mechanism 7 is used to curl the paper at the upper and lower ends of the coin, thereby completing the fully automated rolling and packaging of the coin;

[0066] The unloading channel 10 is used to guide out the rolled coins.

[0067] The feeding mechanism 1 includes a hopper mechanism 11, a centrifugal disc 12, a centrifugal motor, a plum blossom disc 14, a feeding slide 15, a feeding motor 16 and a feeding synchronous belt 17.

[0068] The hopper mechanism 11 includes a lower hopper, a hopper motor and a lower feeding belt. The lower feeding belt is arranged at the bottom end of the lower hopper. The hopper motor drives the lower feeding belt to rotate. The feed port of the lower hopper faces upward, which is used to facilitate people to put coins from the feed port of the lower hopper. After the coins are put into the lower hopper, they fall on the lower feeding belt. The hopper motor drives the lower feeding belt to rotate, and the coins are transported to the discharge port of the lower hopper and fall onto the centrifugal disk 12.

[0069] The centrifugal motor drives the centrifugal disk 12 to rotate, and a rubber pad is fixed at the lower end of the plum blossom disk 14, which is against the upper end of the centrifugal disk 12. The thickness of the rubber pad is greater than the thickness of a coin and less than the thickness of two coins. When the centrifugal disk 12 rotates, the rubber pad is driven to rotate under the action of friction, and the rubber pad drives the plum blossom disk 14 to rotate; one end of the feeding slide 15 cooperates with the centrifugal disk 12, the feeding slide 15 is tangent to the rotation direction of the centrifugal disk 12, and one end of the feeding slide 15 points to the intersection between the centrifugal disk 12 and the plum blossom disk 14. When the centrifugal disk 12 rotates with the coin, the coin enters between the centrifugal disk 12 and the plum blossom disk 14 under the action of centrifugal force, and then is thrown into the feeding slide 15. Since the thickness of the rubber pad is greater than the thickness of a coin and less than the thickness of two coins, the coin entering between the centrifugal disk 12 and the plum blossom disk 14 can only be one coin, and the other coins stacked thereon are hit into the centrifugal disk 12 by the edge of the plum blossom disk 14.

[0070] The feeding synchronous belt 17 cooperates with the feeding chute 15, and the feeding motor 16 drives the feeding synchronous belt 17 to rotate. After the coins enter the feeding chute 15, they are attached between the feeding synchronous belt 17 and the feeding chute 15. The feeding synchronous belt 17 rotates to drive the coins to move to the stacking mechanism 2.

[0071] A waste hole is also opened in the middle of the feeding chute 15 , and a waste box 18 is arranged below the waste hole. When paper scraps or other abnormal coins pass through the feeding chute 15 , the paper scraps or other abnormal coins can fall from the waste hole into the waste box 18 .

[0072] The stacking mechanism 2 includes a first stacking bar 21, a second stacking bar 22, a third stacking bar 23, and a fourth stacking bar 24. The first stacking bar 21, the second stacking bar 22, the third stacking bar 23 and the fourth stacking bar 24 mutually surround a vertical stacking channel. The upper end of the stacking channel is located on one side of the feeding mechanism 1, and the feeding synchronous belt 17 drives the coins to slide into the stacking channel one by one and stack them up.

[0073] The fork support mechanism 3 includes a coin fork 31, a chain 32 and a fork support motor 33. The fork support motor 33 drives the chain 32 to rotate, and the chain 32 drives the coin fork 31 to circulate through the stacking channel. There are three coin forks 31, which are fixedly arranged on the chain 32 at equal intervals. When the chain 32 rotates, it drives the coin fork 31 to circulate through the stacking channel, thereby supporting the stacked coins in the stacking channel in turn.

[0074] The cam mechanism 8 includes a cam motor 81, a driving shaft, a first cam 82, a second cam 83, a third cam 84 and a fourth cam 85. The first cam 82, the second cam 83, the third cam 84 and the fourth cam 85 are all fixedly arranged on the driving shaft, and the cam motor 81 drives the driving shaft to rotate.

[0075] The coin holding mechanism 4 includes a coin holding rubber head 41, a support arm 42, a first linkage rod 43, a second linkage rod 44 and a swing guide rail 45. The swing guide rail 45 is vertically arranged, and its two ends are pivotally connected to the frame. The support arm 42 is slidably arranged on the swing guide rail 45. The coin holding rubber head 41 is fixedly arranged at one end of the support arm 42. The first cam 82 drives the support arm 42 to move vertically back and forth along the swing guide rail 45 through the first linkage rod 43. The second cam 83 drives the swing guide rail 45 to swing through the second linkage rod 44, thereby driving the support arm 42 to swing horizontally back and forth.

[0076] The supporting arm 42 drives the coin supporting rubber head 41 to extend into the lower end of the stacking channel and support the coins on the coin fork 31 . The coin fork 31 is driven by the chain 32 to leave the coin, completing the transfer of the coin from the coin fork 31 to the coin supporting rubber head 41 .

[0077] The rubber roller mechanism 5 includes a first rubber roller 51, a second rubber roller 52, a third rubber roller 53, a fourth rubber roller 54, a rubber roller linkage arm assembly 55, a rubber roller retracting and discharging motor 56, a rubber roller retracting and discharging cam 57 and a roller gear assembly 58. The first rubber roller 51, the second rubber roller 52, the third rubber roller 53 and the fourth rubber roller 54 mutually surround a wrapping channel, the upper end of the wrapping channel is located at the lower end of the stacking channel, the rubber roller retracting and discharging motor 56 drives the rubber roller retracting and discharging cam 57 to rotate, thereby driving the rubber roller linkage arm assembly 55 to simultaneously adjust the mutual opening or closing of the first rubber roller 51, the second rubber roller 52, the third rubber roller 53 and the fourth rubber roller 54.

[0078] The first cam 82 drives the supporting arm 42 to move downward through the first linkage rod 43, so that the coin supporting rubber head 41 supports the coin to the middle of the wrapping channel, and then the rubber roller retracting and discharging motor 56 drives the rubber roller retracting and releasing cam 57 to rotate, driving the rubber roller linkage arm assembly 55 to simultaneously adjust the first rubber roller 51, the second rubber roller 52, the third rubber roller 53 and the fourth rubber roller 54 to close together, so that the first rubber roller 51, the second rubber roller 52, the third rubber roller 53 and the fourth rubber roller 54 can clamp the coin on the coin supporting rubber head 41 at the same time.

[0079] The roller gear assembly 58 includes a roller gear motor 581, a roller gear 582, a first circular arc gear 583, a second circular arc gear 584, four groups of U-groove bearings 585, a slider 586, a first hinge block 587 and a second hinge block 588. The four groups of U-groove bearings 585 are arranged in a rectangular array to form a fixed slideway. The slider 586 is slidably disposed in the fixed slideway. The roller gear 582 is pivoted on the slider 586. The first circular arc gear 583 and the second circular arc gear 584 are respectively meshed with the roller gear 582. The first circular arc gear 583 is fixedly connected to the first rubber roller 51, and the second circular arc gear 584 is fixedly connected to the second rubber roller 52. The roller gear motor 581 drives the roller gear 582 to rotate. One end of the first hinge block 587 is hinged to the first rubber roller 51, and the other end is hinged to the slider 586. One end of the second hinge block 588 is hinged to the second rubber roller 52, and the other end is hinged to the slider 586.

[0080] When the rubber roller linkage arm assembly 55 adjusts the distances among the first rubber roller 51, the second rubber roller 52, the third rubber roller 53 and the fourth rubber roller 54, the first rubber roller 51 and the second rubber roller 52 move, and at the same time, also drive the first hinge block 587 and the second hinge block 588 to move, and then drive the slider 586 to slide along the U-groove bearing 585, thereby ensuring that the first circular arc gear 583, the second circular arc gear 584 and the roller gear 582 move synchronously so that they will not be disengaged. On the other hand, when the first circular arc gear 583 and the second circular arc gear 584 are meshed with the roller gear 582, when the teeth on the first circular arc gear 583 or the second circular arc gear 584 contact the roller on the roller gear 582, the roller on the roller gear 582 will roll, and the two are in rolling friction. Compared with traditional sliding friction, the present invention reduces wear and noise.

[0081] The roller gear motor 581 drives the roller gear 582 to rotate, and at the same time drives the first circular arc gear 583 and the second circular arc gear 584 to rotate, thereby driving the first rubber roller 51 and the second rubber roller 52 to rotate simultaneously.

[0082] The adjusting mechanism 9 comprises an adjusting motor 91, an adjusting rod 92, a first adjusting cam 93, a second adjusting cam 94 and a stacking linkage arm assembly 95. The first adjusting cam 93 and the second adjusting cam 94 are both fixedly arranged on the adjusting rod 92. The adjusting motor 91 drives the adjusting rod 92 to rotate. The first adjusting cam 93 drives the stacking linkage arm assembly 95 to simultaneously adjust the opening or closing of the first stacking bar 21, the second stacking bar 22, the third stacking bar 23 and the fourth stacking bar 24. In the present embodiment, the stacking linkage arm assembly 95 is provided with two groups, and the first adjusting cam 93 is also correspondingly provided with two groups. Each group of the first adjusting cams 93 is correspondingly matched with one group of the stacking linkage arms. Such a design can ensure that the first stacking bar 21, the second stacking bar 22, the third stacking bar 23 and the fourth stacking bar 24 can still remain parallel to each other when moving relative to each other, thereby maintaining smooth opening and closing.

[0083] The second adjusting cam 94 drives the rubber roller retracting and discharging motor 56 to swing, thereby driving the rubber roller linkage arm assembly 55 to simultaneously adjust the mutual opening or closing of the first rubber roller 51, the second rubber roller 52, the third rubber roller 53 and the fourth rubber roller 54. In the present embodiment, the rubber roller linkage arm assembly 55 is provided with two groups, and the second adjusting cam 94 is also correspondingly provided with two groups. Each group of second adjusting cams 94 is correspondingly matched with one group of rubber roller linkage arms. Such a design can ensure that the first rubber roller 51, the second rubber roller 52, the third rubber roller 53 and the fourth rubber roller 54 can still remain parallel to each other when moving relative to each other, thereby maintaining smooth opening and closing.

[0084] The loading slide 15 consists of two parallel tracks, which are fixedly connected to the first stacking bar 21 and the second stacking bar 22 respectively. When the first stacking bar 21 and the third stacking bar 23 are opened or closed, the two tracks are also driven to open and close at the same time to achieve synchronous adjustment.

[0085] When the adjusting motor 91 drives the adjusting rod 92 to rotate, the first adjusting cam 93 drives the stacking linkage arm assembly 95 to adjust the distances between the first stacking bar 21, the second stacking bar 22, the third stacking bar 23 and the fourth stacking bar 24 at the same time; at the same time, the first stacking bar 21 and the third stacking bar 23 also drive the two runways to move respectively to adjust the distance between the two runways; at the same time, the second adjusting cam 94 drives the rubber roller retracting and discharging motor 56 to swing, thereby driving the rubber roller linkage arm assembly 55 to adjust the distances between the first rubber roller 51, the second rubber roller 52, the third rubber roller 53 and the fourth rubber roller 54 at the same time; then, the rubber roller retracting and discharging motor 56 drives the rubber roller retracting and releasing cam 57 to rotate, once again driving the rubber roller linkage arm assembly 55 to adjust the distances between the first rubber roller 51, the second rubber roller 52, the third rubber roller 53 and the fourth rubber roller 54 at the same time, so that they clamp or release the coins.

[0086] The paper winding mechanism 6 includes a reel 61, a paper pulling motor 62, a paper pulling roller group 63, a cutting knife 64, a paper feeding motor 65, a paper feeding roller group 66 and a paper guide paper. The paper pulling motor 62 drives the paper pulling roller group 63 to rotate, and the paper feeding motor 65 drives the paper feeding roller group 66 to rotate. The reel 61, the paper pulling roller group 63, the cutting knife 64 and the paper feeding roller group 66 are arranged in sequence on one side of the rubber roller mechanism 5. One end of the cutting knife 64 is V-shaped, and the edge of the V-shape is covered with serrations, which is conducive to cutting the paper roll. The paper guide paper is arranged between the paper pulling roller group 63 and the paper feeding roller group 66, and is used to guide the paper roll sent by the paper pulling roller group 63 to between the paper feeding roller group 66.

[0087] One end of the paper roll is pulled out from the reel 61, then passes through the paper pulling roller group 63 and the paper feeding roller group 66 in sequence, and finally extends between the second rubber roller 52 and the third rubber roller 53, while making the paper roll between the paper pulling roller group 63 and the paper feeding roller group 66 abut against the V-shaped tip of the cutting knife 64; when the paper pulling roller group 63 clamps the paper roll and stops rotating, the paper feeding roller group 66 continues to drive the paper roll forward, so that the paper roll can be cut by the cutting knife 64, and then the paper feeding roller group 66 continues to rotate to feed the cut paper roll between the second rubber roller 52 and the third rubber roller 53 for wrapping coins.

[0088] When the roller gear motor 581 drives the roller gear 582 to rotate, it also drives the first arc gear 583 and the second arc gear 584 to rotate, thereby driving the first rubber roller 51 and the second rubber roller 52 to rotate simultaneously, thereby driving the coin stack clamped between the first rubber roller 51, the second rubber roller 52, the third rubber roller 53 and the fourth rubber roller 54 to rotate, and cooperates with the roll of paper coming in from between the second rubber roller 52 and the third rubber roller 53, so that the paper roll is wrapped around the side of the coin stack.

[0089] The hook knife mechanism 7 includes an upper hook knife 71 , a lower hook knife 72 , an opening and closing gear assembly 73 , a third linkage rod 74 , a fourth linkage rod 75 and an opening and closing gear adjustment mechanism 76 .

The sliding sleeve 732 is sleeved on the support rod 731, and the opening and closing gear 733 is pivotally connected to the sliding sleeve 732. The upper rack 734 and the lower rack 736 are symmetrically arranged and both mesh with the opening and closing gear 733. The first spring 735 is used to pull the upper rack 734 that has moved upward back to its original position, and the second spring 737 is used to pull the lower rack 736 that has moved downward back to its original position.

[0091] One end of the upper hook knife 71 is fixedly connected to the upper rack 734, and the lower hook knife 72 is fixedly connected to the lower rack 736. The third cam 84 drives the lower rack 736 to move vertically back and forth through the third linkage rod 74. When the lower rack 736 moves downward, it drives the opening and closing gear 733 to rotate, and then drives the upper rack 734 to move upward synchronously, thereby realizing the synchronous reverse movement of the upper rack 734 and the lower rack 736, thereby ensuring that the opening and closing gear 733 is always in the middle position between the upper hook knife 71 and the lower hook knife 72.

[0092] The fourth cam 85 drives the opening and closing gear assembly 73 to deflect through the fourth linkage rod 75, thereby simultaneously driving the upper hook knife 71 and the lower hook knife 72 to swing back and forth horizontally.

[0093] After the coin is wrapped with the rolling paper, the swing arm is swung aside, the upper hook knife 71 and the lower hook knife 72 are separated from each other, and then the hooking end of the upper hook knife 71 and the hooking end of the lower hook knife 72 are simultaneously swung into the wrapping channel. At this time, the upper hook knife 71 and the lower hook knife 72 are respectively located at the upper and lower ends of the coin, and then the upper hook knife 71 and the lower hook knife 72 are closed together and fit with the two ends of the coin, and the roller gear motor 581 drives the roller gear 582 to rotate, thereby driving the coin to rotate, and at the same time, the rolling paper at the two ends of the coin is curled by the upper hook knife 71 and the lower hook knife 72 respectively.

[0094] The opening and closing gear adjustment mechanism 76 includes a paper roll clamping plate 761, a width lifting arm 762 and a lifting platform 763. The paper roll clamping plate 761 is linked to one end of the width lifting arm 762, and the other end of the width lifting arm 762 is directly and movably contacted on the frame. The lifting platform 763 is hinged at the middle position of the width lifting arm 762. The cutting knife 64 and the opening and closing gear assembly 73 are both linked to the lifting platform 763. When the paper roll clamping plate 761 rises to a certain height, the rising height of the lifting platform 763 is equal to half of the rising height of the paper roll clamping plate 761; the cardboard clamping plate directly blocks the upper end of the paper tube. When replacing paper tubes of different heights, the displacement distance of the lifting platform 763 is half of the displacement distance of the cardboard clamping plate. This design ensures that the center point position of the V-shape of the cutting knife 64, the position of the opening and closing gear 733, and the middle position of the paper tube are always maintained on the same horizontal plane.

[0095] Working principle: 1. Coins are put into the feeding port of the lower hopper and fall on the feeding belt. The hopper motor drives the feeding belt to rotate, and the coins are transported to the discharging port of the lower hopper and fall on the centrifugal disc 12. When the centrifugal disc 12 rotates with the coins, the coins enter between the centrifugal disc 12 and the plum blossom disc 14 under the action of centrifugal force, and then are thrown into the feeding chute 15. After the coins enter the feeding chute 15, they are attached between the feeding synchronous belt 17 and the feeding chute 15. The feeding synchronous belt 17 rotates to drive the coins to move into the stacking channel;

[0096] 2. The coin fork 31 holds the stacked coins in the stacking channel, and the supporting arm 42 drives the coin supporting rubber head 41 to extend into the lower end of the stacking channel and hold the coins on the coin fork 31. The coin fork 31 is driven by the chain 32 to leave the coins, completing the transfer of the coins from the coin fork 31 to the coin supporting rubber head 41. The coin supporting rubber head 41 holds the coins to the middle of the wrapping channel;

[0097] 3. The rubber roller retracting and discharging motor 56 drives the rubber roller retracting and releasing cam 57 to rotate, driving the rubber roller linkage arm assembly 55 to simultaneously adjust the first rubber roller 51, the second rubber roller 52, the third rubber roller 53 and the fourth rubber roller 54 to close together, so that the first rubber roller 51, the second rubber roller 52, the third rubber roller 53 and the fourth rubber roller 54 simultaneously clamp the coin on the coin holding rubber head 41;

[0098] 4. When the paper pulling roller group 63 clamps the paper roll and stops rotating, the paper feeding roller group 66 continues to drive the paper roll forward, so that the paper roll can be cut from the cutting knife 64, and then the paper feeding roller group 66 continues to rotate to feed the cut paper roll between the second rubber roller 52 and the third rubber roller 53. When the roller gear motor 581 drives the roller gear 582 to rotate, it also drives the first arc gear 583 and the second arc gear 584 to rotate, thereby driving the first rubber roller 51 and the second rubber roller 52 to rotate simultaneously, thereby driving the coin pile clamped between the first rubber roller 51, the second rubber roller 52, the third rubber roller 53 and the fourth rubber roller 54 to rotate, and cooperates with the paper roll coming from between the second rubber roller 52 and the third rubber roller 53, so that the paper roll is wrapped on the side of the coin pile;

[0099] 5. After the coin is wrapped with the rolling paper, the swing arm is swung aside, the upper hook knife 71 and the lower hook knife 72 are separated from each other, and then the hooking end of the upper hook knife 71 and the hooking end of the lower hook knife 72 are simultaneously swung into the wrapping channel. At this time, the upper hook knife 71 and the lower hook knife 72 are respectively located at the upper and lower ends of the coin, and then the upper hook knife 71 and the lower hook knife 72 are closed together and fit with the two ends of the coin, and the roller gear motor 581 drives the roller gear 582 to rotate, thereby driving the coin to rotate, and at the same time, the upper hook knife 71 and the lower hook knife 72 are used to curl the rolling paper at the two ends of the coin, and the coin is wrapped;

[0100] 6. The first rubber roller 51 , the second rubber roller 52 , the third rubber roller 53 and the fourth rubber roller 54 are opened simultaneously to release the wrapped coins, so that the coins fall into the discharge channel 10 and are guided out through the discharge channel 10 .

[0101] The above does not limit the technical scope of the present invention in any way. Any modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
