Description

Technical Field

[0001] This application relates to the field of paper-plastic product forming equipment technology, and in particular to a synchronous transfer device for pre-folded paper boxes and finished paper-plastic products, and an in-film labeling device. Background Technology

[0002] With the continuous development of the catering industry and the current environmental protection needs of society, green and environmentally friendly paper and plastic lunch boxes are being used by more and more restaurants.

[0003] In related technologies, the production equipment for paper-plastic lunch boxes generally includes a paper feeding and conveying device and a finished product ejection and unloading device. The paper feeding and conveying device feeds the folded paper into the injection molding machine. After the injection molding machine molds the paper, it opens the mold, and the finished product ejection and unloading device removes the finished product from the mold and unloads it. Thus, the production process of paper-plastic lunch boxes requires the use of these two devices in conjunction with multiple operating steps to achieve paper feeding and product unloading. The process is cumbersome, the devices occupy a large space, and the manufacturing cost of the production equipment is high.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0033] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0034] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0035] In the description of this application, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0036] In the embodiments of this application, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0037] In the embodiments of this application, the first direction corresponds to the X-axis (i.e., the left-right direction) of the spatial coordinate axis, the second direction corresponds to the Y-axis (i.e., the front-back direction) of the spatial coordinate axis, and the third direction corresponds to the Z-axis (i.e., the up-down direction) of the spatial coordinate axis.

[0038] In related technologies, the production equipment for paper-plastic lunch boxes generally includes a paper feeding and conveying device and a finished product ejection and unloading device. The paper feeding and conveying device feeds the folded paper into the injection molding machine. After the injection molding machine molds the paper, it opens the mold, and the finished product ejection and unloading device removes the finished product from the mold and discharges it. Thus, the production process of paper-plastic lunch boxes requires multiple steps using these two devices to achieve paper feeding and product unloading, which is cumbersome, requires a large amount of space, and results in high manufacturing costs. This synchronous transfer device can complete both operations in one go: feeding the folded paper into the injection molding machine and removing the finished product from the mold and unloading it. This reduces the number of devices in the equipment, simplifies the design, reduces the space occupied by the equipment, and lowers the manufacturing cost.

[0039] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 ,in, Figure 1 This is a structural diagram of the synchronization transfer device in the embodiments of this application; Figure 2 yes Figure 1 A structural diagram of the side-loading and transfer device of the synchronous transfer equipment in the middle;

[0040] Figure 3 yes Figure 1 A structural diagram of the flipping and paper feeding device in the synchronous transfer equipment; Figure 4 yes Figure 1 A partial structural diagram of the flipping and paper feeding device in the synchronous transfer equipment; Figure 5 yes Figure 1 Structural diagram of the tilting and unloading device in the synchronous transfer equipment; Figure 6This is a structural diagram of the in-film labeling device in the embodiments of this application; in a first aspect, this application provides a synchronous transfer device for pre-folded paper boxes and paper-plastic finished products, including an injection molding machine. The synchronous transfer device includes a flipping paper feeding device 100, a side-picking and transferring device 200, and a flipping unloading device 300, all arranged on the same side of the injection molding machine.

[0041] like Figures 1 to 6 As shown below, the specific structure of the synchronous transfer equipment for pre-folded cardboard boxes and paper-plastic finished products will be described in detail.

[0042] The flipping feeding device 100 is used to feed the pre-folded cardboard box into the first acquiring unit 210. The flipping unloading device 300 is used to acquire and unload the paper-plastic finished product from the second acquiring unit 220. The side-picking and transferring device 200 is used to transfer the pre-folded cardboard box into the molding die inside the injection molding machine through the first acquiring unit 210, and to remove the paper-plastic finished product from the molding die inside the injection molding machine through the second acquiring unit 220. The side-picking and transferring device 200 can move back and forth synchronously along the second direction and can transfer between the outside of the injection molding machine and the molding die inside the injection molding machine.

[0043] In the side-grabbing and transfer device 200, the first acquisition unit 210 is a transfer fixture, on which multiple storage positions and suction nozzles corresponding to the storage positions are arranged side by side for receiving and absorbing pre-folded cardboard boxes. The second acquisition unit 220 is also a transfer fixture, on which multiple suction nozzles are arranged side by side for absorbing the formed paper-plastic finished product.

[0044] During operation, the flipping paper feeding device 100 feeds multiple pre-folded cardboard boxes into the first picking unit 210. The side-picking and transferring device 200 moves the first picking unit 210 and the second picking unit 220 along a second direction, causing them to enter the molding die inside the injection molding machine. At this time, the molding die is in the open state. Subsequently, the pre-folded cardboard boxes on the first picking unit 210 are placed in the cavity of the molding die, and the second picking unit 220 picks up the paper-plastic finished product from the molding die. Then, the first picking unit 210 and the second picking unit 220 leave the injection molding machine and return to their initial positions. The flipping unloading device 300 picks up the paper-plastic finished product from the second picking unit 220 and unloads it. In this way, the feeding and unloading processes of the pre-folded cardboard boxes and the paper-plastic finished products are simplified, and the feeding and unloading time of the pre-folded cardboard boxes and the paper-plastic finished products is saved.

[0045] In some examples, such as Figures 1 to 6As shown, the side-mounted transfer device 200 includes a first moving module 230, a first support part 240, and a transverse drive mechanism 250. The first moving module 230 is disposed on one side of the injection molding machine. The first moving module 230 drives the first support part 240 to reciprocate along a first direction. The transverse drive mechanism 250 is connected to the first support part 240. The first acquisition part 210 and the second acquisition part 220 are respectively connected to the transverse drive mechanism 250 so that the first acquisition part 210 and the second acquisition part 220 reciprocate along the first direction in opposite directions or in opposite directions.

[0046] The specific structure of the first moving module 230 is not limited in this embodiment. In this embodiment, the first moving module 230 can be a linear motor, a cylinder-slider drive mechanism, or a lead screw drive mechanism.

[0047] The transverse drive mechanism 250 is used to drive the first acquisition unit 210 and the second acquisition unit 220 to move back and forth in the first direction, and can adjust the distance between the first acquisition unit 210 and the second acquisition unit 220 so that the first acquisition unit 210 and the second acquisition unit 220 can use different forming molds. This further facilitates the first acquisition unit 210 to feed the pre-folded cardboard box into the forming mold, and facilitates the second acquisition unit 220 to take out the paper-plastic finished product from the forming mold.

[0048] During operation, the first moving module 230 is used to drive the first support part 240 and the transverse drive mechanism 250 to move back and forth along the first direction. This is to enable the first acquiring part 210 to move closer to or further away from the flipping paper feeding device 100, thereby facilitating the feeding of pre-folded paper boxes, and to enable the second acquiring part 220 to move closer to or further away from the flipping unloading device 300, thereby facilitating the unloading of paper-plastic finished products.

[0049] In some examples, such as Figures 1 to 6 As shown, the transverse drive mechanism 250 includes a drive motor 251, a first pulley transmission mechanism 252, a first belt pressure plate 253, and a second belt pressure plate 254. The drive motor 251 and the first pulley transmission mechanism 252 are both connected to the first support portion 240. The drive motor 251 is drive-connected to the first pulley transmission mechanism 252, and the first belt pressure plate 253 and the second belt pressure plate 254 are respectively connected to the first pulley transmission mechanism 252. The first acquisition portion 210 is connected to the first belt pressure plate 253, and the second acquisition portion 220 is connected to the second belt pressure plate 254. Thus, by driving the first pulley transmission mechanism 252 with the drive motor 251, the first belt pressure plate 253 and the second belt pressure plate 254 can move closer to or further away from each other, thereby causing the first acquisition portion 210 and the second acquisition portion 220 to move closer to or further away from each other.

[0050] In some examples, such as Figures 1 to 6As shown, the flipping and feeding device 100 includes a second moving module, a moving frame 110, a first lifting module 120, a first flipping module 130, and a first suction component 140. The second moving module is disposed on one side of the injection molding machine. The second moving module drives the moving frame 110 to reciprocate along a first direction. The first lifting module 120 is disposed on the moving frame 110, the first flipping module 130 is disposed on the first lifting module 120, and the first suction component 140 is disposed on the first flipping module 130. Thus, through the second moving module, the moving frame 110, and the first lifting module 120, the first flipping module 130, and the first suction component 140, which are directly or indirectly disposed on the moving frame 110, can be driven to reciprocate along the first direction, so that the first suction component 140 can approach the folding device 600 described below and take out the pre-folded paper box from the folding device 600.

[0051] The specific structure of the second moving module is not limited in this embodiment. In this embodiment, the second moving module can be a linear motor, a cylinder-slider drive mechanism, or a lead screw drive mechanism.

[0052] In the flipping paper feeding device 100, the first suction assembly 140 includes a first flipping shaft 141, a first flipping seat 142, a first driving cylinder 143, and a first suction part 144. The two ends of the first flipping shaft 141 are rotatably connected to the first lifting seat 125 and the second lifting seat 126 respectively. The first flipping seat 142 is sleeved on the first flipping shaft 141 and is fixed to the first flipping shaft 141. The first driving cylinder 143 is disposed on the first flipping seat 142, and the first suction part 144 is connected to the cylinder shaft of the first driving cylinder 143.

[0053] Furthermore, the first guide portion 132 is sleeved on the first flip shaft 141, so that the first guide portion 132 is fixed to the first flip shaft 141. In this way, with the cooperation of the first guide portion 132 and the first guide plate 131, the first flip shaft 141 can rotate, so that the first flip seat 142 can switch between horizontal and vertical directions.

[0054] For example, when the first flipping seat 142 is arranged horizontally, the first suction part 144 is also arranged horizontally. The first drive cylinder 143 drives the first suction part 144 to move toward the folding device 600 described below. The first suction part 144 sucks out the pre-folded cardboard box from the folding device 600. Then, the first drive cylinder 143 drives the first suction part 144 to move away from the folding device 600 described below. The above process completes the pre-folded cardboard box picking.

[0055] For example, when the first flipping seat 142 is vertically positioned, the first suction part 144 is also vertically positioned. The first drive cylinder 143 drives the first suction part 144 to move towards the first acquisition part 210 and places the pre-folded cardboard box onto the first acquisition part 210. Then, the first drive cylinder 143 drives the first suction part 144 to move away from the first acquisition part 210, thus completing the process of placing the pre-folded cardboard box into the first acquisition part 210.

[0056] In some examples, such as Figures 1 to 6 As shown, the first lifting module 120 includes a first lifting motor 121, a first shaft 122, a second pulley transmission mechanism 123, a third pulley transmission mechanism 124, a first lifting seat 125, and a second lifting seat 126. The first lifting motor 121 is mounted on the movable frame 110 and is connected to the first shaft 122. Both ends of the first shaft 122 are rotatably connected laterally to the movable frame 110. The first lifting seat 125 and the second lifting seat 126 are slidably connected to both ends of the movable frame 110, respectively. One end of the first shaft 122 is connected to the first lifting seat 125 through the second pulley transmission mechanism 123, and the other end of the first shaft 122 is connected to the second lifting seat 126 through the third pulley transmission mechanism 124. The first suction assembly 140 is connected to the first lifting seat 125 and the second lifting seat 126, respectively. Thus, the first lifting motor 121 drives the first shaft 122 to rotate, and the first shaft 122 simultaneously drives the second pulley transmission mechanism 123 and the third pulley transmission mechanism 124 to work, so that the first lifting seat 125 and the second lifting seat 126 move back and forth synchronously along the third direction.

[0057] In some examples, such as Figures 1 to 6 As shown, the first flipping module 130 includes a first guide plate 131 and a first guide portion 132. The first guide plate 131 is disposed on the movable frame 110. The first guide portion 132 is provided with a first guide groove. The first guide groove includes a first vertical segment, a first curved segment, and a first horizontal segment that are connected and arranged sequentially along a third direction. The length of the first vertical segment is greater than the length of the first horizontal segment. One end of the first guide portion 132 is fixed to the first suction assembly 140, and the other end of the first guide portion 132 is slidably connected to the first guide groove. Thus, through the sliding cooperation between the first guide plate 131 and the first guide portion 132, the first flipping shaft 141 is rotated, thereby allowing the first flipping seat 142 to switch between vertical and horizontal orientations.

[0058] In some examples, such as Figures 1 to 6As shown, the flipping and unloading device 300 includes an unloading component 310, a fixed frame 320, a second lifting module 330, a second flipping module 340, and a second suction component 350. The unloading component 310 is located on one side of the injection molding machine, the fixed frame 320 is located on the unloading component 310, the second lifting module 330 is located on the fixed frame 320, the second flipping module 340 is located on the second lifting module 330, and the second suction component 350 is located on the second flipping module 340.

[0059] The second lifting module 330 in the flipping feeding device 300 and the first lifting module 120 in the flipping paper feeding device 100 have the same specific structure and operating principle, and will not be described in detail here.

[0060] The second flipping module 340 in the flipping feeding device 300 and the first flipping module 130 in the flipping paper feeding device 100 have the same specific structure and operating principle, and will not be described in detail here.

[0061] In addition, the second suction assembly 350 includes a second flip shaft, a second flip seat, a second drive cylinder and a second suction part. The two ends of the second flip shaft are rotatably connected to the second lifting module 330, the second flip seat is sleeved on the second flip shaft and fixed to the second flip shaft, the second drive cylinder is located on the second flip seat, and the second suction part is connected to the cylinder shaft of the second drive cylinder.

[0062] Furthermore, the second flip module 340 is connected to the second flip shaft. With the cooperation of the second flip module 340, the second flip shaft can rotate, allowing the second flip seat to switch between horizontal and vertical directions.

[0063] For example, when the second flipping seat is vertically positioned, the second suction part is also vertically positioned. The second drive cylinder drives the second suction part to move toward the second acquisition part 220 and removes the paper-plastic finished product from the second acquisition part 220. Then, the second drive cylinder drives the second suction part to move away from the second acquisition part 220, and the above process completes the material removal of the paper-plastic finished product.

[0064] For example, when the second flipping seat is arranged horizontally, the second suction part is also arranged horizontally, and the second drive cylinder can drive the second suction part to move closer to or away from the feeding assembly 310. When the second suction part moves closer to the feeding assembly 310, the feeding assembly 310 will pick up the paper-plastic finished product on the second suction part and feed it into the feeding channel.

[0065] In some examples, such as Figures 1 to 6 As shown, the unloading assembly 310 includes a third moving module, a support frame 311, and a flipping unit 312. The third moving module is located on one side of the injection molding machine, the support frame 311 is located on the third moving module, and the flipping unit 312 includes multiple units arranged in parallel on the support frame 311.

[0066] The specific structure of the third moving module is not limited in this embodiment. In this embodiment, the third moving module can be a linear motor, a cylinder-slider drive mechanism, or a lead screw drive mechanism.

[0067] In addition, the flipping unit 312 includes a flipping motor 3121, a rotating shaft 3122, and an adsorption element 3123 arranged in parallel on the rotating shaft 3122. The flipping motor 3121 is mounted on the support frame 311, and the rotating shaft 3122 is rotatably connected to the support frame 311. The flipping motor 3121 is connected to the rotating shaft 3122. During operation, the flipping motor 3121 can rotate the rotating shaft 3122, causing the adsorption element 3123 to flip 180°. This facilitates the removal of the paper-plastic finished product from the second suction section, and then the product is flipped and discharged into the discharge channel, thus achieving automated discharge that is convenient and fast.

[0068] A second aspect of this application provides an in-film labeling device, including a paper separating device 400, a transplanting robot 500, a folding and pressing device 600, and a synchronous transfer device;

[0069] Paper separating device 400 is used to separate multiple individual sheets of paper; transfer robot is used to transfer multiple individual sheets of paper to folding device 600; folding device 600 is used to pre-fold the paper; synchronous transfer device is used to remove the pre-folded paper from folding device 600.

[0070] The paper separating device 400 includes a fourth moving device, a transfer seat, a paper stacking frame, and a paper feeding assembly. The fourth moving device is arranged along a first direction, the transfer seat is connected to the fourth moving device, the paper stacking frame is connected above the fourth moving device, and the paper feeding assembly is located directly below the paper stacking frame. The fourth moving device can drive the transfer seat to move along the first direction, allowing the transfer seat to move below the paper stacking frame or move out from below the paper stacking frame. The paper feeding assembly is used to pick up paper from the paper stacking frame and move it onto the transfer seat.

[0071] Specifically, the paper feeding assembly includes a paper feeding cylinder and a paper feeding nozzle, with the paper feeding cylinder connected to the paper feeding nozzle.

[0072] For example, the transfer seat moves to below the paper stacking frame, the paper drop cylinder drives the paper drop nozzle through the transfer seat and to the paper stacking frame. The paper drop nozzle picks up the bottom layer of paper in the paper stacking frame, and then the paper drop cylinder drives the paper drop nozzle to move down, so that the paper moves onto the transfer seat.

[0073] The folding device 600 includes a folding fixture, a transfer robot picks up the paper and transfers it onto the folding fixture, and then pre-folds the paper into a box.

[0074] In some examples, such as Figures 1 to 6As shown, the transfer robot includes a three-axis robot and a suction fixture. The three-axis robot is located between the paper separating device and the folding device 600, and the suction fixture is connected to the three-axis robot.

[0075] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described.
