With the above settings, the automation of wrapping the article to be packed and folding and flattening the wrapping paper at both ends of the package is realized, reducing the processing difficulty and improving the production efficiency and work efficiency.

[0069] Embodiment 2

[0070] A packing device, as Figures 2 to 14 shown, includes a frame 104, a conveyor platform 105 installed on the frame 104, and a paper wrapping device 200 and a paper folding device 100 arranged in sequence along the conveying direction of the conveyor platform 105;

[0071] The paper wrapping device 200 is used to wrap the wrapping paper around the outer periphery of the article to be packed to form a semi-finished package;

[0072] The paper folding device 100 includes an upper folding mechanism for folding the wrapping paper at both ends of the semi-finished package downwards from top to bottom, a side folding mechanism for folding the wrapping paper at both ends of the semi-finished package inwards from both sides, and a lower folding mechanism for folding the wrapping paper at both ends of the semi-finished package upwards from bottom to top.

[0073] Specifically, the present invention has a novel structure and an ingenious design. When working, the object to be packaged is transported to the conveyor 105 on the external production line, and the object to be packaged is transported to the paper wrapping device 200 through the conveyor 105. The paper wrapping device 200 wraps the wrapping paper around the periphery of the object to be packaged to form a semi-finished package, and then continues to be transported to the paper folding device 100 through the conveyor 105. At this time, the periphery of the package is wrapped with wrapping paper, and the wrapping paper at both ends of the package is in an unfolded state. When the package is delivered to the folding station of the paper folding device 100, the paper folding device 100 is folded. 00's upper folding mechanism, side folding mechanism and lower folding mechanism, the upper folding mechanism pushes the wrapping paper at both ends of the package to fold from top to bottom, and then the side folding mechanism pushes the wrapping paper at both ends of the package to fold from both sides inward, and finally, the lower folding mechanism folds the wrapping paper at both ends of the package from bottom to top, so that the package is wrapped with wrapping paper and then the wrapping paper at both ends are folded and flattened, and then discharged to the next production line. Under the above settings, the automatic wrapping of the packaged items and the folding and flattening of the wrapping paper at both ends of the package are realized, which reduces the processing difficulty and improves production efficiency and work efficiency.

[0074] In this embodiment, the paper wrapping device 200 includes a paper pulling mechanism 201 and a paper wrapping mechanism 202;

[0075] The paper pulling mechanism 201 includes a paper pulling movable frame 203, a paper pulling drive assembly, and a paper clamping assembly 204 mounted on the paper pulling movable frame 203. The paper pulling drive assembly drives the paper pulling movable frame 203 to move forward and backward and up and down. A baffle is provided on the front side of the paper pulling movable frame 203 for supporting the items to be packaged, thereby ensuring stable transportation of the items to be packaged.

[0076] The paper wrapping mechanism 202 includes a paper wrapping support 205, a paper wrapping drive assembly, and a flattening assembly 206 mounted on the paper wrapping support 205. The paper wrapping drive assembly is used to drive the flattening assembly 206 of the paper wrapping support 205 to wrap the wrapping paper along the periphery of the packaged item.

[0077] Specifically, the paper pulling mechanism 201 clamps the front end of the wrapping paper through the paper clamping assembly 204. After the item to be packed is sent to the working station of the paper wrapping device 200, the paper pulling drive assembly drives the paper pulling moving frame 203 to move backward, driving the wrapping paper to move along the transmission direction of the conveyor table 105. Then, the paper pulling drive assembly drives the paper pulling moving frame 203 to move upward. Since the paper pulling moving frame 203 moves upward, a part of the wrapping paper is driven to move upward, and a part of the wrapping paper is located on the flattening assembly 206. And the item to be packed falls on the wrapping paper as the paper pulling moving frame 203 moves. At the same time, the paper wrapping drive assembly drives the paper wrapping support 205 to move along the outer periphery of the item to be packed, and the flattening assembly 206 is used to push the wrapping paper to wrap around the outer periphery of the item to be packed, facilitating the conveyance of the wrapped semi-finished product to the paper folding device 100. During the transmission process, the wrapping paper on the paper pulling moving frame 203 is pulled and falls above the wrapped semi-finished product as the wrapped semi-finished product moves. At this time, the paper folding device 100 folds and edges the wrapping paper at both ends of the wrapped semi-finished product.

[0078] In the paper pulling mechanism 201 of this embodiment, a paper receiving assembly is provided on the paper pulling moving frame 203.

A paper clamping torsion spring 213114 is provided between the paper clamping movable block 212 and the paper clamping shaft roller. A paper clamping wheel 214 is rotatably provided at one end of the paper clamping movable block 212. The paper clamping wheels 214 correspond to the paper receiving synchronous belts 210 one by one, and the paper clamping wheels 214 cooperate with the paper receiving synchronous belts 210 to clamp the wrapping paper. Specifically, when the paper receiving assembly works, under the action of the paper receiving drive member 207, the paper receiving synchronous belts 210 are driven to rotate, and in cooperation with the paper clamping wheels 214 of the paper clamping assembly 204, the paper receiving and pulling of the wrapping paper are realized. And the plurality of paper receiving synchronous belts 210 are arranged in a row, reducing the occurrence of wrinkles on the wrapping paper.

[0080] Further, paper pulling front and rear sliding seats 215 are provided on both sides of the paper pulling moving frame 203; the paper pulling front and rear sliding seats 215 are horizontally slidably connected to the inner wall of the frame 104.

[0081] The paper pulling drive assembly includes a front and rear paper pulling drive portion 216 for driving the front and rear paper pulling slides 215 to move forward and backward, and a lifting paper pulling drive portion for driving the paper pulling movable frame 203 to move up and down;

[0082] The lifting and pulling paper driving part includes a lifting and pulling paper driving component 217, a paper pulling active gear 218 and a paper pulling shaft 219. The paper pulling shaft 219 and the lifting and pulling paper driving component 217 are both installed on the front and rear paper pulling slides 215. The two ends of the paper pulling shaft 219 are rotatably provided with paper pulling driven gears 220135, and the two ends of one side of the paper pulling movable frame 203 are provided with paper pulling racks 221 that are engaged with the paper pulling driven gear 220135.

[0083] Specifically, under the above setting, the paper pulling movable frame 203 is driven to move forward and backward by driving the front and rear paper pulling slides 215 to move forward and backward; in the lifting and lowering paper pulling drive part, the up and down lifting and lowering movement of the paper pulling movable frame 203 is realized, and due to the cooperation between the paper pulling driven gear 220135 and the paper pulling rack 221, the movement accuracy is high, thereby improving the processing accuracy.

[0084] In this embodiment, the flattening assembly 206 includes a flattening spindle 222 mounted on the paper wrapping support 205 and a plurality of flattening rollers 223 rotatably disposed in a row on the flattening spindle 222 ;

[0085] The paper wrapping bracket 205 is provided with front and rear paper wrapping slides 224 on both sides; the front and rear paper wrapping slides 224 are horizontally slidably connected to the inner wall of the frame 104;

[0086] The paper wrapping drive assembly includes a front and rear paper wrapping drive portion 225 for driving the front and rear paper wrapping slides 224 to move forward and backward, and a lifting paper wrapping drive portion for driving the paper wrapping support 205 to move up and down;

[0087] The lifting and lowering paper wrapping drive part includes a lifting and lowering paper wrapping drive member 226, a paper wrapping driving gear 227 and a paper wrapping shaft 228. The paper wrapping shaft 228 and the lifting and lowering paper wrapping drive member 226 are both mounted on the front and rear paper wrapping slides 224. The two ends of the paper wrapping shaft 228 are rotatably provided with paper wrapping driven gears 229135. Both ends of one side of the paper wrapping bracket 205 are provided with paper wrapping racks 230 that are engaged and connected with the paper wrapping driven gears 229135. Under the above arrangement, the up and down lifting and lowering movements of the paper wrapping bracket 205 are realized, and the movement accuracy is improved due to the cooperation between the paper wrapping driven gear 229135 and the paper wrapping rack 230.

[0088] Specifically, the arrangement of the flattening pressing wheel 223 avoids abrasion of the wrapping paper, and ensures that the flattening assembly 206 can reliably and stably flatten the wrapping paper and wrap it around the periphery of the item to be packaged.

[0089] In this embodiment, after the wrapping paper device 200 wraps the wrapping paper around the outer periphery of the packed item to form a semi-finished package, the conveyor table 105 conveys the semi-finished package to the paper folding device 100 for folding the wrapping paper of the semi-finished package, and folding the wrapping paper at both ends of the semi-finished package;

[0090] Specifically, the packing device further includes a lifting table 106, a lower folding mechanism installed on the frame 104, an upper folding mechanism installed at the bottom of the lifting table 106, a side folding mechanism installed at the bottom of the lifting table 106, and a lifting drive mechanism 107 installed on the frame 104.

[0094] The lower folding mechanism includes two lower folding components 103 arranged opposite to each other, and the two lower folding components 103 are respectively located on both sides of the conveyor table 105;

[0095] When the paper folding device 100 works, the semi-finished package is sent from the conveyor table 105, the outer periphery of the package is wrapped with wrapping paper, and the wrapping paper at both ends of the package is in an unhemmed state. When the package is sent to the hemming station of the paper folding device 100, the upper folding mechanism pushes the wrapping paper at both ends of the package to be pressed and folded from top to bottom, then the side folding mechanism pushes the wrapping paper at both ends of the package to be pressed and folded from both sides to the inside, and finally, the lower folding mechanism presses the wrapping paper at both ends of the package from bottom to top to fold and flatten the wrapping paper at both ends of the package, and then discharges it to the next production line. With the above settings, the automation of folding and flattening the wrapping paper at both ends of the package is realized, the processing difficulty is reduced, and the production efficiency and work efficiency are improved; further, the lifting drive mechanism 107 drives the lifting table 106 to move up and down, which is convenient to drive the upper folding mechanism and the side folding mechanism to move up and down, realize the avoidance of the package, and facilitate the package to be transmitted into the station and discharged from the station on the conveyor table 105.

An upper folding pressing plate 115 is disposed at the front end of the upper folding swing seat 113. A driving wheel 116 for slidably abutting against the package is rotatably disposed at the rear end of the upper folding swing seat 113.

[0097] Specifically, the working principle of the upper folding assembly 101 is as follows: When the package reaches the hemming station, the lifting drive mechanism 107 drives the lifting table 106 to move downward, causing the upper folding assembly 101 to move downward. When the upper folding assembly 101 moves downward until the driving wheel 116 abuts against the upper surface wrapping paper of the package, the upper folding swing seat 113 slides until the upper folding pressing plate 115 presses the wrapping paper at both ends of the package from top to bottom. When the lifting table 106 rises, the driving wheel 116 gradually disengages from the package. Under the action of the torsion spring 114, the upper folding pressing plate 115 is driven to open and disengage from both ends of the package.

The external threads of the two second transmission screws 129 are in opposite directions. The two second transmission screws 129 are respectively threadedly connected to the two side-folding bases 126.

[0101] Specifically, under the above setting, the second drive motor 128 drives one of the second transmission screws 129 to rotate, which can drive the side folding bases 126 of the same side folding assembly 102 to move closer to or away from each other, thereby conveniently driving the side folding pressure plate 127 to push and flatten the packaging paper from both sides of the package; wherein, the upper folding swing seat 113 is rotatably set at the bottom of the movable base part 122, and the output ends of the front and rear driving parts 120 are connected to the movable base part 122. Under this setting, the upper folding assembly 101 can achieve a giving way effect, facilitate the operation of the side folding assembly 102, and the structure is reliable.
