[0037] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0038] Please refer to Figures 1 to 4 , a lottery automated packaging device, comprising a shaping and clamping component 2, a preheating component 3, a welding component and a conveyor belt 1 for transmitting a packaging film of a lottery roll;

[0039] The shaping clamping assembly 2, the preheating assembly 3 and the welding assembly are successively arranged above the conveying belt 1 along the conveying direction of the conveying belt 1. The shaping clamping assembly 2 is used to fit the two edges of the packaging film of the lottery roll to be packaged, and the preheating assembly 3 is used to preheat the two edges;

[0040] The welding assembly includes a heating assembly 4, a rotating assembly 5, a first heating plate 6 and a second heating plate 7;

[0041] The first heating plate 6 and the second heating plate 7 are arranged opposite to each other on the same horizontal plane, and a welding gap 8 is provided between the circumferential side wall of the first heating plate 6 and the circumferential side wall of the second heating plate 7 for two edges of the packaging film of the lottery roll to be packaged to pass through;

[0042] The rotating component 5 is used to drive the first heating disk 6 and the second heating disk 7 to rotate simultaneously. The tangent direction generated by the rotation of the first heating disk 6 and the second heating disk 7 at the edge of the welding gap 8 is the same as the conveying direction of the conveyor belt 1. The heating component 4 is connected to the first heating disk 6 and the second heating disk 7 respectively.

[0043] From the above description, it can be seen that the beneficial effect of the utility model is that: a shaping clamping component 2, a preheating component 3 and a welding component are sequentially arranged on the conveyor belt 1. Under the transmission of the conveyor belt 1, the two edges of the packaging film of the lottery roll to be packaged are first clamped and fitted by the shaping clamping component 2, and the edges of the packaging film of the lottery roll are pre-fitted and shaped to prepare for subsequent welding. Then, the preheating component 3 preheats the edges to prevent them from being directly heated at the welding component and causing some positions to be melted. Then, the first heating plate 6 and the second heating plate 7 are used to weld the two edges of the packaging film of the lottery roll. The rotation of the first heating plate 6 and the second heating plate 7 cooperates with the transmission of the packaging film of the lottery roll on the conveyor belt 1, and each position of the edge is tightly welded at the welding gap 8, which can avoid the occurrence of tearing the packaging film of the lottery roll and improve the packaging quality.

[0044] Furthermore, the rotating assembly 5 includes a driving motor, a first gear 51, a first connecting shaft 52, a second connecting shaft 53, a second gear 54 and a third gear 55;

[0045] The first gear 51 is coaxially rotatably connected to the first heating plate 6 via the first connecting shaft 52, the first gear 51 is meshedly connected to the second gear 54, the second gear 54 is laminatedly connected to the third gear 55, and the third gear 55 is coaxially rotatably connected to the second heating plate 7 via the second connecting shaft 53;

[0046] The third gear 55 is offset relative to the second gear 54 in a direction away from the first gear 51 to form the welding gap 8 between the first heating plate 6 and the second heating plate 7;

[0047] The driving motor is drivingly connected to the first gear 51 .

[0048] From the above description, it can be seen that the rotating component 5 is mainly composed of a driving motor, a first connecting shaft 52, a second connecting shaft 53, a first gear 51 and a second gear 54. Through the meshing of the first gear 51 and the second gear 54, the first heating plate 6 and the second heating plate 7 are simultaneously controlled by a driving motor to rotate; at the same time, the design of the meshing structure will make the welding gap 8 too small, and it is easy to tear the packaging film of the lottery roll during welding. Therefore, a third gear 55 is provided which is staggered and stacked with the second gear 54. The size of the welding gap 8 is controlled by the size of the position offset of the second gear 54, thereby ensuring that the packaging film of the lottery roll will not be torn and the packaging is completed.

[0049] Furthermore, packaging stripes 9 are provided on the circumferential side walls of the first heating plate 6 and the second heating plate 7 .

[0050] It can be seen from the above description that by providing the packaging stripes 9, indentations are produced on the two edges of the packaging film of the lottery roll, so that it is welded in a shape with indentations, thereby improving the sealing effect.

[0051] Furthermore, the shaping and clamping assembly 2 includes a first mounting seat 21, a first clamping wheel 22 and a second clamping wheel 23;

[0052] The first clamping wheel 22 and the second clamping wheel 23 are both rotatably disposed on the first mounting seat 21;

[0053] The packaging stripes 9 are provided on the circumferential side walls of the first clamping wheel 22 and the second clamping wheel 23, and a first gap 24 is provided between the circumferential side walls of the first clamping wheel 22 and the second clamping wheel 23 for the two edges of the packaging film of the lottery roll to be packaged to pass through;

[0054] The first gap 24 corresponds to the welding gap 8 .

[0055] From the above description, it can be seen that the shaping clamping assembly 2 relies on the first clamping wheel 22 and the second clamping wheel 23 to complete the clamping action. The rotation of the first clamping wheel 22 and the second clamping wheel 23 cooperates with the transmission of the packaging film of the lottery roll itself on the conveyor belt 1, which can produce the effect of gradually bringing the two edges of the packaging film of the lottery roll together and completing the clamping action at the narrowest point of the first gap 24. At this time, an indentation left by the packaging stripe 9 is generated at the edge. After passing through the first gap 24, even if the edge of the packaging film of the lottery roll bounces open due to its own flexibility, it can still maintain the shape of being about to fit each other to a certain extent, so as to facilitate subsequent preheating and welding.

[0056] Further, the preheating assembly 3 includes a second mounting seat 31, a first heating plate 32 and a second heating plate 33;

[0057] The first heating plate 32 and the second heating plate 33 are disposed opposite to each other on the second mounting seat 31 , and a second gap 34 is defined between the first heating plate 32 and the second heating plate 33 for two edges of the packaging film of the lottery roll to be packaged to pass through.

[0058] From the above description, it can be seen that the preheating component 3 is used to preheat the edge of the packaging film of the lottery roll. Its heating temperature is lower than the temperature of the welding component, so that the edge of the packaging film of the lottery roll is slightly softened to avoid it being directly heated by the high temperature of the welding component.

[0059] Further, the heating component 4 includes a power supply, an electromagnet 41 and a solenoid valve;

[0060] The power supply is connected to the electromagnet 41 through the solenoid valve, and the electromagnet 41 is connected to the first heating plate 6 and the second heating plate 7 respectively.

[0061] It can be seen from the above description that the first heating plate 6 and the second heating plate 7 are both heated by electromagnetic disks, which have high heating efficiency and are easy to control.

[0062] Furthermore, the welding assembly also includes a third mounting seat 10 and a position adjustment assembly 11;

[0063] The first heating plate 6 and / or the second heating plate 7 are arranged on the third mounting seat 10 through the position adjustment component 11, and the position adjustment component 11 is used to make the first heating plate 6 and the second heating plate 7 approach or move away from each other.

[0064] From the above description, it can be known that the position adjustment component 11 is provided to fine-tune the position of the first heating plate 6 and / or the second heating plate 7, so as to control the size of the welding gap 8 to meet the actual packaging requirements.

[0065] Furthermore, a feed sensing device is provided on the conveyor belt 1.

[0066] As can be seen from the above description, the feed sensing device can sense the packaging film of the lottery roll entering the conveyor belt 1, thereby controlling the transmission process of the packaging film of the lottery roll to ensure that the packaging film of the lottery roll is packaged one by one in sequence.

[0067] Embodiment 1:

In addition, packaging stripes 9 are provided on the circumferential side walls of the first heating plate 6 and the circumferential side walls of the second heating plate 7 .

[0069] In this embodiment, the automated packaging equipment mainly includes three processes, and the packaging films of the lottery rolls are transmitted one by one through the conveyor belt 1 and the feed sensing device, so that they pass through the above three processes in sequence, as follows:

[0070] 1. Shaping

[0071] The two edges of the packaging film of the lottery roll are separated at the beginning, which is not convenient for some preheating operations. Therefore, the two edges of the packaging film of the lottery roll are first clamped by the shaping clamping component 2, so that the two edges are first close to each other and fit together. After shaping and clamping, the two edges of the packaging film of the lottery roll can be approximately regarded as two parallel lines that are very close to each other;

[0072] 2. Preheating

[0073] Since the edge of the packaging film of the lottery roll is easy to melt itself when it is directly exposed to the welding temperature, a preheating component 3 is provided; the preheating component 3 includes a second mounting seat 31, a first heating plate 32 and a second heating plate 33; the first heating plate 32 and the second heating plate 33 are relatively arranged on the second mounting seat 31, and a second gap 34 is provided between the first heating plate 32 and the second heating plate 33 for the two edges of the packaging film of the lottery roll to be packaged to pass through.

[0074] When passing through the second gap 34, two edges of the packaging film of the lottery roll contact the first heating plate 32 and the second heating plate 33 respectively, so as to be preheated and slightly softened.

[0075] 3. Welding

[0076] Under the action of the conveyor belt 1, the two edges of the packaging film of the preheated lottery roll will enter the welding assembly and fit each other at the welding gap 8, and at the same time, they will be welded by the high temperature of the first heating plate 6 and the second heating plate 7; the welding gap 8 is the position where the circumferential side wall of the first heating plate 6 and the circumferential side wall of the second heating plate 7 are closest to each other;

[0077] During the welding process, the first heating plate 6 and the second heating plate 7 rotate continuously, and the tangent direction generated by the rotation of the first heating plate 6 and the second heating plate 7 at the edge of the welding gap 8 is the same as the conveying direction of the conveyor belt 1, that is, the edge of the first heating plate 6 close to the welding gap 8 and the edge of the second heating plate 7 close to the welding gap 8 both rotate along the conveying direction of the conveyor belt 1, thereby cooperating with the movement of the packaging film of the lottery roll to complete the welding of various positions of its two edges.
