DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. The components of the present application implemented as described and shown in the drawings here can be arranged and designed in various different configurations.

[0034] Example 1

[0035] refer to Figure 1-6 A cutlery packaging machine comprises a frame 1 and a feeding unit 2, a conveyor belt unit 3, a napkin wrapping unit 4, and a paper tape wrapping unit 5 installed on the frame 1; the feeding unit 2 is located on one side of the conveyor belt unit 3; the conveyor belt unit 3 is located above the napkin wrapping unit 4; the paper tape wrapping unit 5 is located below the napkin wrapping unit 4;

[0036] The unloading unit 2 places the cutlery on the napkin and conveys it to the conveyor belt unit 3. The napkin and the cutlery are conveyed to the napkin wrapping unit 4 through the conveyor belt unit 3. The napkin wrapping unit 4 wraps the napkin around the cutlery and conveys it to the paper tape wrapping unit 5. The paper tape wrapping unit 5 wraps the paper tape around the napkin.

[0037] In this embodiment, after the unloading unit 2 places the knife and fork on the napkin, it conveys the knife and fork and the napkin to the conveyor belt unit 3, and the conveyor belt unit 3 then conveys the knife and fork to the napkin wrapping unit 4 below for wrapping; after the napkin is wrapped around the knife and fork, it falls to the paper tape wrapping unit 5 below for paper tape wrapping.

[0038] By arranging the unloading unit 2, the conveyor belt unit 3, the napkin paper wrapping unit 4, and the paper tape wrapping unit 5, the overall volume of the cutlery packaging machine is reduced, making it easy to use in a western restaurant. By adopting an automated method to replace manual work for packaging cutlery, production efficiency is improved and the labor intensity of staff is reduced.

[0039] Preferably, the unloading unit 2 includes a paper feeding module 21, a first unloading module 22 for placing a knife on a napkin, a second unloading module 23 for placing a fork on a napkin, and a first conveyor belt 24; the paper feeding module 21, the first unloading module 22, and the second unloading module 23 are arranged in sequence above the first conveyor belt 24.

[0040] In this embodiment, the paper feeding module 21 cuts a bundle of napkins into napkins of the same size and conveys them forward through the first conveyor belt 24. When the napkins are conveyed to the first unloading module 22, the first unloading module 22 places the knife on the napkins; when the napkins are conveyed to the second unloading module 23, the second unloading module 23 places the fork on the napkin. After the knife and fork are on the napkins, the first conveyor belt 24 continues to convey the knife, fork and napkins forward.

[0041] The paper feeding module 21 includes a conveying roller and a cutting assembly. The whole bundle of napkins is installed on the conveying roller, and the napkins are cut by the cutting assembly. The cutting assembly can adopt a cutting structure similar to that in CN114933200A, or other mechanisms available on the market that can achieve napkin cutting can be selected.

[0042] The first material discharging module 22 and the second material discharging module 23 place the materials in the feeding trough, and push the cutlery through the motor so that the cutlery is placed on each napkin paper one by one. The feeding direction of the materials is from top to bottom, or the materials are discharged in an inclined downward direction.

[0043] Preferably, a rolling module 25 and a folding channel 26 are sequentially provided on the first conveyor belt 24; after the two sides of the napkin are indented by the rolling module 25 and then pass through the folding channel 26, the two sides of the napkin are folded inwardly of the napkin.

[0044] In this embodiment, the rolling module 25 is preferably placed between the paper feeding module 21 and the first material discharging module 22, and the folding channel 26 is arranged on the side of the second material discharging module 23 away from the first material discharging module 22. The paper feeding module 21 conveys the napkin through the rolling module 25, so that indentations are formed on both sides of the napkin, and then the first material discharging module 22 and the second material discharging module 23 discharge the napkin in sequence, and then after passing through the folding channel 26, the two sides of the napkin are gradually folded toward the knife and fork, so that the two sides of the napkin are attached to the knife and fork.

[0045] Preferably, the conveyor belt unit 3 includes a second conveyor belt 31 and a third conveyor belt 32 ; the second conveyor belt 31 and the third conveyor belt 32 are respectively located at two sides of the napkin wrapping unit 4 .

[0046] In this embodiment, the napkins and cutlery enter the second conveyor belt 31 through the first conveyor belt 24, and the second conveyor belt 31 continues to convey the napkins and cutlery, so that one end of the napkin is conveyed to the third conveyor belt 32, and the cutlery located in the middle of the napkin falls from the gap between the second conveyor belt 31 and the third conveyor belt 32 to the napkin wrapping unit 4. At this time, the cutlery is located on the napkin wrapping unit 4, and the two ends of the napkin are respectively on the first conveyor belt 24 and the second conveyor belt 31. In this way, when the napkin is subsequently wrapped, the napkin wrapping unit 4 drives the two sides of the napkin to rotate, so that the napkin is wrapped around the cutlery, avoiding the situation that the cutlery is located at one end of the napkin when it is conveyed by only one conveyor belt, and the cutlery is easily separated from the napkin during wrapping.

[0047] The first conveyor belt 24 , the second conveyor belt 31 , and the third conveyor belt 32 are all commercially available conveyor belts.

[0048] Preferably, the napkin wrapping unit 4 includes a rotating block 41, symmetrically arranged support blocks 42, a first driving module 43 for driving the rotating block 41 to rotate, and a second driving module 44 for driving the symmetrically arranged support blocks 42 to move closer to or away from each other; the rotating block 41 and the support block 42 are both provided with an opening 45; the support block 42 is located inside the rotating block 41; the rotating block 41 is used to drive the napkin to rotate so that the napkin wraps the knife and fork.

[0049] In this embodiment, the specific working process of the napkin wrapping unit 4 is as follows: the knife and fork are subjected to the action of gravity, and the napkin is pressed through the rotating block 41 and the opening 45 of the supporting block 42 in turn, and is placed on the supporting block 42. The first driving module 43 drives the rotating block 41 to rotate, driving the two ends of the napkin to be wrapped around the supporting block 42, and the second driving module 44 drives the supporting blocks 42 to move away from each other, so that the napkin wraps the knife and fork and makes the knife and fork fall onto the paper tape wrapping unit 5. In this way, the napkin can wrap the knife and fork, and the napkin is not easy to spread out when being transported downward.

[0050] Preferably, the napkin wrapping unit 4 further comprises a sensor; the sensor is used to detect whether there are knives and forks on the supporting block 42 .

[0051] In this embodiment, by setting a sensor to detect whether there are knives and forks on the support block 42 to determine whether to drive the rotating block 41 to rotate, the wrapping operation can be better started when the knives and forks enter the support block 42. This avoids the situation where the knives and forks do not enter the support block 42 or only partially enter the support block 42 due to errors in the previous process, while the rotating block 41 continues to rotate according to the original beat, thereby damaging the equipment.

[0052] Preferably, the paper tape wrapping unit 5 includes a flip wheel 51, a third driving module 52 for driving the flip wheel 51 to rotate, and a guide plate 53; the guide plate 53 is located on the side of the flip wheel 51 away from the unloading unit 2; the guide plate 53 is rotatably connected to the frame 1; the guide plate 53 is provided with a first rebound member; the flip wheel 51 is rotatably connected to the frame 1; the flip wheel 51 is provided with a plurality of grooves 511 for placing knives and forks; symmetrically arranged wrapping plates 54 are provided on both sides of the flip wheel 51; the positions of the wrapping plates 54 correspond to those of the grooves 511.

[0053] In this embodiment, the guide plate 53 and the wrapping plate 54 form a paper tape conveying passage, and the wrapping plate 54 and the groove 511 are located in the same plane.

[0054] The specific working process of the paper tape wrapping unit 5 is as follows: the napkin wrapping unit 4 transports the knife and fork wrapped with the napkin paper to the groove 511 on the flip wheel 51. At the same time, the knife and fork are pressed on the wrapping plate 54 on which the paper tape is transported. The third driving module 52 drives the flip wheel 51 to rotate, driving the knife and fork to move to the guide plate 53. As the wrapping plate 54 rotates, the paper tape is wound around the napkin paper. The flip wheel 51 continues to rotate, thereby pressing the knife and fork wrapped with the paper tape and napkin paper to move downward. The guide plate 53 is subjected to pressure and moves downward with the knife and fork. When the knife and fork leave the guide plate 53, the guide plate 53 returns to its original position through the action of the first rebound member.

[0055] The paper tape can be wound on the napkin by the support of the guide plate 53, and the guide plate 53 can rotate. After the paper tape is wound, the guide plate 53 can move with the cutlery to avoid affecting the operation of the cutlery. In this way, the structure of the paper tape roll is greatly simplified, and the miniaturization of the device is achieved.

[0056] Preferably, the paper tape wrapping unit 5 also includes a paper tape conveying module 55 and a sealing module 56 for conveying the paper tape to the paper tape wrapping unit 5 through the guide plate 53; the sealing module 56 includes a heating welding head 561, a wrapping auxiliary plate 562, and a driving component 563 for driving the heating welding head 561 to approach or move away from the wrapping auxiliary plate 562; the wrapping auxiliary plate 562 is rotatably connected to the frame 1 and is located below the guide plate 53; the wrapping auxiliary plate 562 is provided with a second rebound member; the heating welding head 561 is slidably connected to the frame 1; the heating welding head 561 is used to heat and seal the rolled paper tape.

[0057] In this embodiment, the paper tape conveying module 55 cuts a bundle of paper tape into pieces of paper tape of the same size, and then conveys the paper tape to the guide plate 53 and the wrapping plate 54. The cutlery wrapped with napkins is placed on the flip wheel 51. After the webbing wrapping is completed, the cutlery presses the guide plate 53 and rotates, then separates from the guide plate 53 and contacts the wrapping auxiliary plate 562. The sealing module 56 approaches the paper tape and heats and seals it. The flip wheel 51 continues to drive the cutlery to rotate, so that the cutlery separates from the wrapping auxiliary plate 562 and is conveyed to the next position. The wrapping auxiliary plate 562 is acted upon by the second rebound member. After the cutlery separates from the wrapping auxiliary plate 562, the wrapping auxiliary plate 562 returns to its initial position.

[0058] Preferably, it also includes a finished product discharge plate 6 and an auxiliary plate 7 both installed on the frame 1; the finished product discharge plate 6 is located below the paper tape wrapping unit 5; the auxiliary plate 7 is located on the side of the paper tape wrapping unit 5 close to the sealing module 56; a discharge port 61 is formed between the finished product discharge plate 6 and the auxiliary plate 7.

[0059] In this embodiment, the turning wheel 51 drives the cutlery to pass through the auxiliary plate 7 and then enter the finished product discharge plate 6 from the discharge port 61. The auxiliary plate 7 is in an arc shape. The auxiliary plate 7 is used to prevent the cutlery from being separated from the groove 511 when the turning wheel 51 rotates until the cutlery enters the discharge port 61.

[0060] Example 2

[0061] A method for packaging cutlery comprises the following steps:

[0062] Step 1: The unloading unit 2 conveys the napkin through the rolling module 25, places the knife and fork in the middle of a napkin, and then folds the two sides of the napkin inward through the folding channel 26, and then conveys it to the conveyor belt unit;

[0063] Step 1 is specifically as follows: the paper feeding module 21 gradually conveys the cut napkins onto the first conveyor belt 24. The first conveyor belt 24 first drives the napkins through the rolling module 25 to press the two sides of the napkins into indentations, and then drives the middle of the napkins to move to the first unloading module 22 and the second unloading module 23. After the first unloading module 22 and the second unloading module 23 drop the knife and fork to the middle of the napkins, the first conveyor belt 24 continues to drive the napkins and the knife and fork through the paper folding channel, and the two sides of the napkins are gradually folded toward the knife and fork, and then the first conveyor belt 24 conveys the napkins and the knife and fork to the conveyor belt unit 3. Since the indentations are pressed by the rolling module 25, the two sides of the napkins are not easy to warp after being folded, although they are not fixed.

[0064] Step 2: The conveyor belt unit 3 conveys the cutlery and the napkin to the napkin wrapping unit 4; when the sensor senses that the cutlery enters the support block 42, the rotating block 41 rotates to wrap the napkin around the cutlery, and at the same time, the paper tape conveying module 55 conveys the paper tape to the guide plate 53 and the wrapping plate 54;

[0065] Step 2 is specifically as follows: the second conveyor belt 31 conveys the napkin toward the third conveyor belt 32. Since the knife and fork are in the middle of the napkin, after the front end of the napkin enters the third conveyor belt 32, the knife and fork just leave the second conveyor belt 31, and enter the support block 42 from the gap between the second conveyor belt 31 and the third conveyor belt 32. The rotating block 41 rotates, thereby driving the napkins on the second conveyor belt 31 and the third conveyor belt 32 to be rolled onto the support block 42. The symmetrically arranged support blocks 42 move away from each other, so that the napkin is wrapped around the knife and fork and falls onto the flip wheel 51.

[0066] Step 3: The napkin wrapped with the cutlery enters the flip wheel 51 and contacts the wrapping plate 54 and the guide plate 53. When the flip wheel 51 rotates, the wrapping plate 54 drives the paper tape to wrap around the napkin. As the flip wheel 51 rotates, the cutlery wrapped with the paper tape gradually separates from the guide plate 53, and the sealing module 56 heat-seals the paper tape. After the heat sealing is completed, the flip wheel 51 transports the cutlery to the discharge port 61.

[0067] Step 3 is specifically as follows: the paper tape is transported to the guide plate 53 and the wrapping plate 54; the cutlery is placed on the groove 511 and the wrapping plate 54 and pressed on the paper tape, the flip wheel 51 rotates to place the cutlery on the guide plate 53, the flip wheel 51 rotates to drive the wrapping plate 54 to wrap the paper tape around the napkin, the flip wheel 51 continues to rotate, pressing the cutlery and the guide plate 53 to move downward, so that the cutlery gradually separates from the guide plate 53 and contacts with the wrapping auxiliary plate 562, the sealing module 56 heats and seals the paper tape, the flip wheel 51 continues to rotate, so that the cutlery gradually separates from the wrapping auxiliary plate 562, and the cutlery gradually enters the discharge port 61 along the auxiliary plate 7, and is then transported to the finished product area.

[0068] By placing the knife and fork in the middle of the napkin, firstly making indentations on both sides of the napkin, folding both sides of the napkin towards the knife and fork before rolling and wrapping, the knife and fork are not easy to be separated from the napkin after the napkin wraps the knife and fork. Then, by rotating the turning wheel 51, the paper tape is rolled, sealed, and the finished product is conveyed, which shortens the conveying distance, has a compact structure, and has high production efficiency, and is suitable for use in spaces such as restaurants.

[0069] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
