Description

Technical Field

[0001] The utility model relates to a packaging mechanism, in particular to a material supporting and box expanding mechanism. Background Art

[0002] When packaging the products after production, the traditional method is generally to manually pack the products into boxes one by one. With the development of technology, some automatic boxing equipment has emerged at present. The manipulator can move the products from the transfer line into the box one by one to achieve automatic boxing. However, this boxing method requires the products to be transferred to a platform for sorting first, and then the sorted products are transferred to the packaging box, and a mechanism for expanding the packaging box is also required to ensure that the box opening is expanded outwards. Therefore, multiple mechanisms need to cooperate with each other to achieve product boxing, the overall design is relatively complex, and the production equipment cost is relatively high. Therefore, there is an urgent need for a mechanism with a more simplified structure to assist in boxing products. Content of the Utility Model

[0003] The purpose of the utility model is to provide a material supporting and box expanding mechanism to solve one or more technical problems existing in the prior art, and at least provide a beneficial choice or creation condition.

[0004] The solution of the utility model to solve its technical problems is as follows:

[0005] A material supporting and box expanding mechanism, comprising: a supporting device; a material supporting frame located above the supporting device, and a through hole penetrating in the up and down direction is formed inside the periphery of the material supporting frame; a material supporting component, including two symmetrically arranged material supporting plates on the top side of the material supporting frame, the two material supporting plates can rotate upwards to above the through hole to form a material supporting surface, and the two material supporting plates can rotate downwards and extend into the through hole.

[0006] This technical solution has at least the following beneficial effects: The packaging box is placed on the supporting device, and the opening of the packaging box is directly opposite to the through hole. The two material supporting plates in the material supporting component rotate upwards to above the through hole. At this time, the two material supporting plates can block the through hole, and the top surfaces of the two material supporting plates are located on a plane, jointly forming a material supporting surface for supporting products. After moving the products to be boxed to the material supporting surface, the two material supporting plates rotate downwards, opening the through hole, and the two material supporting plates can continue to rotate downwards and extend into the through hole to push the cover plate on the top side of the packaging box outwards. And the products originally located on the material supporting surface are moved downwards into the packaging box with the assistance of peripheral mechanisms. After boxing, the two material supporting plates rotate upwards to reset to prepare for the next boxing. In this way, the material supporting plates can be used to support the products, facilitating the transfer and sorting of the products, and can also be used to push the cover plate of the packaging box outwards to ensure that the products can smoothly enter the packaging box downwards, simplifying the overall structural design, being beneficial to reducing the equipment production cost, and improving the transfer efficiency of the sorted products, thereby improving the product boxing efficiency.

[0007] As a further improvement of the above technical solution, the blank holding component includes a first rotation driving member, an upper connecting seat and an upper rotating shaft. The left and right sides of the blank holding frame are respectively connected with the upper connecting seat and the first rotation driving member. The two upper rotating shafts are respectively rotatably connected to the two upper connecting seats along the axis in the front-rear direction. The two first rotation driving members are respectively drivingly connected to the two upper rotating shafts, and the two blank holding plates are respectively connected to the two upper rotating shafts. The two first rotation driving members are respectively located on the left and right sides of the blank holding frame, and drive the two blank holding plates to rotate respectively through the two upper rotating shafts. Since the upper rotating shaft is rotatably connected to the upper connecting seat, the height of the rotation axis of the blank holding plate can be lifted by using the upper connecting seat, so that when the two blank holding plates rotate downward, the cover plates on the left and right sides of the packing box are further pushed outwards. When it is necessary to transfer and arrange the products again, the two first rotations drive the two blank holding plates to rotate upward to above the hole respectively, so that the top sides of the two blank holding plates jointly form a blank holding surface.

[0008] As a further improvement of the above technical solution, a pressing edge that bends downward is formed on one side of each of the two blank holding plates close to each other. When the blank holding plate rotates downward, the pressing edge can first contact the cover plate on the top side of the packing box, which is beneficial to further push outwards the cover plate on the top side of the packing box. And an angle is formed between the pressing edge and the blank holding plate, which can limit the side position of the cover plate of the packing box, preventing the situation that the cover plate is easily slipped downward relative to the cover plate of the packing box when the blank holding plate pushes the cover plate of the packing box outwards.

[0009] As a further improvement of the above technical solution, the blank holding frame assembly further includes a material pushing unit. The material pushing unit includes a second rotation driving member, a lower connecting seat, a lower rotating shaft and a box supporting block. The lower connecting seat and the second rotation driving member are respectively connected to the bottom side of the blank holding frame. The lower rotating shaft is rotatably connected to the lower connecting seat along the axis in the left-right direction. The second rotation driving member is drivingly connected to the lower rotating shaft. The box supporting block is connected to the lower rotating shaft. The material pushing units are symmetrically arranged on the front and rear sides of the blank holding frame. There are also box supporting blocks on the front and rear sides of the blank holding frame that can push outwards the cover plates on the front and rear sides of the packing box. Specifically, second rotation driving members for providing rotational driving force are respectively connected to the front and rear sides of the blank holding frame. When the packing box is placed below the hole, the two second rotation driving members respectively drive the box supporting blocks to push outwards the cover plates on the front and rear sides of the packing box through the two lower rotating shafts. When the product is packed and the packing box is removed, the two second rotation driving members drive the two cover plates to rotate inwards and reset, avoiding interference with the cover plates of the packing box. Similarly, the lower connecting seat can reduce the height of the rotation axis of the box supporting block, so that the box supporting block has a larger amplitude when rotating, thereby better pushing outwards the cover plates of the packing box.

[0010] As a further improvement of the above technical solution, the two box-supporting blocks are respectively connected with downwardly protruding paddles on one side facing each other. When the two box-supporting blocks rotate downward, the paddles first contact the cover plate of the packaging box, and the paddles can be used to further extend the rotating arm for prying the cover plate, which is conducive to further prying the cover plates on the front and rear sides of the packaging box outward.

[0011] As a further improvement of the above technical solution, a conveying surface extending in the front-to-back direction is formed on the supporting device. The packaging box is placed on the conveying surface and can be automatically conveyed to the bottom of the hole in the front-to-back direction. After the product is packed, it is moved out from under the hole, further improving the convenience of product packing.

[0012] As a further improvement of the above technical solution, the supporting device includes a base frame and a roller conveyor, the roller conveyor is arranged on the base frame, and the conveying surface is formed on the top side of the roller conveyor. A plurality of rotating rollers on the roller conveyor are used to form a conveying surface for conveying products, so as to realize the moving of packaging boxes into boxes and the moving of packaging boxes out of boxes for unloading.

[0013] As a further improvement of the above technical solution, the base frame is connected with an adjusting screw rod, and the roller conveyor is connected to the adjusting screw rod, and the adjusting screw rod can drive the roller conveyor to move up and down. When in use, according to the different heights of the packaging boxes to be transferred, the position of the roller conveyor can be adjusted up and down by adjusting the screw rod, so as to better meet the packing requirements of packaging boxes of different specifications and sizes, and improve the versatility of overall use.

[0014] As a further improvement of the above technical solution, the roller conveyor is provided with clamping plates at intervals along the left and right directions, and the two clamping plates are respectively located above the conveyor. When the packaging box reaches the position below the hole under the transfer of the roller conveyor, the two clamping plates can be respectively located at the left and right sides of the packaging box, which is conducive to limiting the position of the packaging box and ensuring the packaging of the product.

[0015] As a further improvement of the above technical solution, at least one of the clamping plates is connected with a telescopic driving member, and the telescopic driving member is drivingly connected with a push block, and the telescopic driving member can drive the push block to move in a direction close to or away from another clamping plate. Before loading the packaging box, the telescopic driving member drives the push block away from the other clamping plate. When the packaging box reaches the position below the hole under the transfer of the roller conveyor, the telescopic driving member can drive the push block to press the packaging box to the other clamping plate, so that the packaging box can be further limited in the left and right directions, and the position of the packaging box can be better limited.

[0024] Referring to Figure 1 and Figure 2 , a material supporting and box opening mechanism includes a supporting device, a material supporting frame 100 and a material supporting component. Among them, the material supporting frame 100 is located above the supporting device, and a hole penetrating in the up and down direction is formed inside the periphery of the material supporting frame 100. In actual application, the material supporting frame 100 and the supporting device can be fixed on the same machine frame, so as to facilitate the overall movement; the material supporting component includes two material supporting plates 210 symmetrically arranged on the top side of the material supporting frame 100 from left to right. The rotation axes of the two material supporting plates 210 both extend in the front and back direction. The two material supporting plates 210 can rotate upward to above the hole and form a material supporting surface. At this time, the side edges of the two material supporting plates 210 close to each other can be abutted to form a continuous material supporting surface, or a certain gap can be reserved between the two material supporting plates 210 to form a material supporting surface with a break in the middle, so as to reduce the interference when the two material supporting plates 210 move. The two material supporting plates 210 can rotate downward and extend into the hole.

[0025] As can be seen from the above, the packaging box is placed on the supporting device, and the opening of the packaging box is directly opposite to the hole. The two material supporting plates 210 in the material supporting component rotate upward to above the hole. At this time, the two material supporting plates 210 can block the hole, and the top surfaces of the two material supporting plates 210 are on the same plane, jointly forming a material supporting surface for supporting the product. After moving the product to be boxed to the material supporting surface, the two material supporting plates 210 rotate downward to open the hole, and the two material supporting plates 210 can continue to rotate downward and extend into the hole to push the cover plate on the top side of the packaging box outward. And the product originally located on the material supporting surface moves downward into the packaging box with the assistance of the peripheral mechanism. After the boxing is completed, the two material supporting plates 210 rotate upward to reset to prepare for the next boxing. In this way, the material supporting plates 210 can be used not only to support the product, facilitating the transfer and arrangement of the product, but also to push the cover plate of the packaging box outward to ensure that the product can smoothly enter the packaging box downward, simplifying the overall structural design, being beneficial to reducing the production cost of the equipment, and improving the transfer efficiency of the arranged product, thereby improving the product boxing efficiency.

[0026] The material supporting component is internally provided with a driving source configured to drive two material supporting plates 210 to rotate, so as to drive the two material supporting plates 210 to rotate up and down. It can be to use the same driving source to drive the two material supporting plates 210 to rotate in opposite directions, or to use two driving sources to drive the two material supporting plates 210 to rotate. Specifically, the material supporting component includes a first rotary driving member 220, an upper connecting seat 230 and an upper rotating shaft 240. The left and right sides of the material supporting frame 100 are respectively connected with the upper connecting seat 230 and the first rotary driving member 220. The two upper rotating shafts 240 are respectively rotatably connected to the two upper connecting seats 230 along the axis in the front-rear direction. The two first rotary driving members 220 are respectively drivingly connected to the two upper rotating shafts 240. The two material supporting plates 210 are respectively connected to the two upper rotating shafts 240. The first rotary driving member 220 is mainly used to provide a driving force for the rotation of the upper rotating shaft 240, and there are various structural forms, such as a rotary cylinder, a motor, etc. In practical applications, upper connecting seats 230 are respectively connected to the front and rear sides of the material supporting frame 100, and the two end portions of the upper rotating shaft 240 are respectively rotatably connected to the two upper connecting seats 230, so as to improve the rotation stability of the upper rotating shaft 240.

[0027] The two first rotary driving members 220 are respectively located on the left and right sides of the material supporting frame 100, and drive the two material supporting plates 210 to rotate respectively through the two upper rotating shafts 240. Since the upper rotating shaft 240 is rotatably connected to the upper connecting seat 230, the upper connecting seat 230 can be used to raise the height of the rotation axis of the material supporting plate 210, so that the two material supporting plates 210 further push the cover plates on the left and right sides of the packaging box outwards when rotating downwards. When it is necessary to further transfer and arrange the products, the two first rotaries drive the two material supporting plates 210 to rotate upwards to above the hole, so that the top sides of the two material supporting plates 210 jointly form a material supporting surface.

[0028] In order to improve the effect of pushing the cover plate of the packaging box outwards to the left and right sides, in this embodiment, the sides of the two material supporting plates 210 close to each other are both formed with a pressing edge 211 that bends downwards. When the material supporting plate 210 rotates downwards, the pressing edge 211 can first contact the cover plate on the top side of the packaging box, which is beneficial to further push the cover plate on the top side of the packaging box outwards, and a certain angle is formed between the pressing edge 211 and the material supporting plate 210, which can limit the side position of the cover plate of the packaging box and prevent the situation that the cover plate is prone to slipping downwards relative to the cover plate of the packaging box when the material supporting plate 210 pushes the cover plate of the packaging box outwards.

[0029] The top side of some packaging boxes has only two cover plates. In this case, the two cover plates can be opened outward by relying on the two supporting plates 210 respectively. The top side of some packaging boxes has four cover plates. In addition to using two material-dipping plates to dig out the two cover plates, two more material-digging plates are required to dig out the other two cover plates. Specifically, the support frame 100 assembly also includes a material-digging unit, which includes a second rotating drive member 250, a lower connecting seat 260, a lower rotating shaft 270 and a box-supporting block 280. The lower connecting seat 260 and the The second rotating drive member 250 is respectively connected to the bottom side of the supporting rack 100, and the lower rotating shaft 270 is rotatably connected to the lower connecting seat 260 along the axis in the left and right directions. The second rotating drive member 250 is drivingly connected to the lower rotating shaft 270, and the box support block 280 is connected to the lower rotating shaft 270. The material shifting unit is symmetrically arranged on the front and rear sides of the supporting rack 100. The second rotating drive member 250 is mainly used to provide a rotational driving force, and its structural forms include various forms, such as a rotating cylinder or a motor. The front and rear sides of the support rack 100 are also provided with box-supporting blocks 280 that can prop the cover plates on the front and rear sides of the packaging box outward. Specifically, the front and rear sides of the support rack 100 are respectively connected with second rotating drive components 250 for providing rotational driving force. When the packaging box is placed under the hole, the two second rotating drive components 250 respectively drive the box-supporting blocks 280 through the two lower rotating shafts 270 to prop the cover plates on the front and rear sides of the packaging box outward. When the products are packed and removed from the packaging box, the two second rotating drive components 250 drive the two cover plates to rotate inward and reset to avoid interference with the cover plates of the packaging box. Similarly, the lower connecting seat 260 can reduce the height of the rotation axis of the box-supporting block 280, so that the box-supporting block 280 can rotate with a larger amplitude, thereby better propping the cover plates of the packaging box outward.

[0030] Furthermore, the two box-supporting blocks 280 are connected to the opposite sides thereof with downwardly protruding paddles 281. When the two box-supporting blocks 280 rotate downward, the paddles 281 first contact the cover plate of the packaging box, and the paddles 281 can be used to further extend the rotating arm for prying the cover plate, which is conducive to further opening the cover plates on the front and rear sides of the packaging box.

[0031] The supporting device may only provide a fixed supporting surface, or may directly load and unload the packaging box. Specifically, the supporting device is formed with a conveying surface extending in the front-to-back direction. The packaging box is placed on the conveying surface and can be automatically conveyed to the bottom of the hole in the front-to-back direction. After the product is packed, it is moved out from under the hole, further improving the convenience of product packing.

[0032] The supporting device can adopt a belt conveyor, a chain conveyor, etc. to form the above-mentioned conveying surface. In order to facilitate the expansion of the external structure on the conveying surface, multiple rotating rollers can be used to form the conveying surface. Specifically, the supporting device includes a chassis and a roller conveyor 310. The roller conveyor 310 is arranged on the chassis, and the conveying surface is formed on the top side of the roller conveyor 310. A plurality of rollers are arranged at intervals in the front-rear direction in the roller conveyor 310, and the plurality of rollers are driven to rotate synchronously by a transmission chain, thereby forming a conveying surface with a plurality of gaps. In this way, a lower conveying surface for conveying the packing boxes is formed by the plurality of rotating rollers on the roller conveyor 310, realizing the transfer of the packing boxes into the packing and the removal and blanking after packing.

[0033] During actual packing, according to different packaging requirements, the required packing boxes will also be different. In order to better adapt to packing boxes of different specifications and sizes, in this embodiment, an adjusting screw rod 320 is connected to the chassis, and the roller conveyor 310 is connected to the adjusting screw rod 320. The adjusting screw rod 320 can drive the roller conveyor 310 to move up and down. When in use, according to the different height dimensions of the packing boxes to be transferred, the position of the roller conveyor 310 can be adjusted up and down by the adjusting screw rod 320, so as to better meet the packing requirements for packing boxes of different specifications and sizes and improve the versatility of the overall use.

[0034] The adjusting screw rod 320 can be an electric screw rod or a manual screw rod. The number of adjusting screw rods 320 can be set to only one, but in this case, the load on the adjusting screw rod 320 is relatively large, and it is difficult to drive the roller conveyor 310 to adjust the height smoothly. Therefore, the number of adjusting screw rods 320 can be multiple, such as two. The two adjusting screw rods 320 are respectively arranged on the left and right sides of the roller conveyor 310, and the two adjusting screw rods 320 drive the roller conveyor 310 to move up and down on the left and right sides of the roller conveyor 310 respectively, so as to greatly improve the stability of the adjustment. In order to make the two adjusting screw rods 320 move synchronously, transmission wheels can be respectively connected to the rotating pairs of the two adjusting screw rods 320, and the two transmission wheels are connected by a synchronous belt transmission, so that the two adjusting screw rods 320 move synchronously.

[0035] In order to ensure that the packing box can be accurately transferred to the place, in this embodiment, the roller conveyor 310 is provided with clamping plates 330 at intervals in the left-right direction. The two clamping plates 330 are respectively located above the conveyor. In practical applications, one clamping plate 330 can be installed on the fixed structure on one side of the roller conveyor 310. A support rod can be connected to the fixed structure in the middle of the roller conveyor 310. The support rod passes upward through the space between two spaced rollers, and then the other clamping plate 330 can be connected to the support rod. When the packing box reaches the position below the hole under the transfer of the roller conveyor 310, the two clamping plates 330 can be respectively located on the left and right sides of the packing box, which is beneficial to limit the position of the packing box and ensure the realization of product packing.

[0036] Further, at least one of the clamping plates 330 is connected with a telescopic driving member 340. The telescopic driving member 340 is drivingly connected with a push block 341. The telescopic driving member 340 can drive the push block 341 to move in a direction close to or away from the other clamping plate 330. The telescopic driving member 340 is mainly used to provide a driving force in a straight line direction, and there are various structural forms, such as cylinders, electric lead screws or hydraulic cylinders, etc. Before loading the packing box, the telescopic driving member 340 drives the push block 341 to move away from the other clamping plate 330. When the packing box reaches the position below the hole under the transfer of the roller conveyor 310, the telescopic driving member 340 can drive the push block 341 to press the packing box against the other clamping plate 330. In this way, the packing box can be further limited in the left-right direction, and the position of the packing box can be better limited.

[0037] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention. These equivalent variations or substitutions are all included within the scope defined by the claims of this application.
