Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, and in particular to an automatic positioning and feeding mechanism and a box-making machine. Background Technology

[0002] Packaging boxes, as the most common packaging method in daily life, are widely used in various fields, especially in the sales packaging sector, due to their multiple advantages such as convenient transportation, protection of goods, and promotion of sales. From food and daily necessities to electronic products and cosmetics, they are almost ubiquitous. This packaging method not only provides consumers with a convenient carrying and storage experience, but also provides businesses with a platform to showcase their products and enhance their brand image.

[0003] In practice, packaging boxes, especially for goods sold in sets, face considerable challenges. These sets often contain items of varying sizes and shapes; for example, a cosmetic set might include a tall, thin serum bottle, a flat powder compact, and lipstick tubes of different sizes. Because of these significant differences in size and shape, a series of problems arise when these items are required to be centered within the same box for aesthetic purposes. Specifically, due to the different sizes of the items, their heights from the bottom edge of the box also vary, making it difficult to securely place all items into the box at once during the packaging process. This not only increases the complexity and time-consuming nature of the packaging but also risks damaging the items due to handling errors, thus impacting the consumer's shopping experience. Utility Model Content

[0004] The main purpose of this utility model is to propose an automatic positioning and feeding mechanism and a boxing machine, which aims to solve the problem that it is difficult to reliably pack multiple items of different sizes and shapes into the same packaging box at one time.

[0005] To achieve the above objectives, this utility model proposes an automatic positioning and feeding mechanism, including a support frame, and further comprising:

[0006] The conveying unit includes multiple conveyor belts, with gaps between adjacent conveyor belts for placing items, and loading and unloading ports at both ends of the conveyor belts.

[0007] The positioning unit is located on the side of the support frame near the discharge port, and includes at least one movable positioning block that can move on the conveyor belt to position the items conveyed on the conveyor unit.

[0008] A limiting part, located above the conveying part, includes at least two limiting plates that can move closer to or further apart from each other, for limiting the items conveyed on the conveying part.

[0009] In some embodiments, the conveying unit further includes a first motor and a drive shaft. The first motor is connected to the drive shaft, and all conveyor belts are connected to the drive shaft. The first motor drives the drive shaft to rotate, and all conveyor belts move along with the drive shaft to convey items.

[0010] In some embodiments, the positioning unit further includes a second motor and a first lead screw connected to each other, a positioning block is disposed on the first lead screw, the second motor drives the first lead screw to rotate, and the positioning block moves on the conveyor belt along with the rotation of the first lead screw.

[0011] In some embodiments, a positioning block is provided in the gap between each pair of adjacent conveyor belts, and a positioning block and a second motor are provided on each first lead screw, with the first lead screw, positioning block and second motor being provided in a one-to-one correspondence.

[0012] In some embodiments, the positioning unit further includes a distance sensor, which is disposed at one end of the support frame near the discharge port and is used to detect the distance between the positioning block and the distance sensor.

[0013] In some embodiments, the limiting part includes a mounting frame disposed on a support frame, the mounting frame being located above the conveyor section, and at least one set of width adjustment components disposed on the mounting frame, each set of width adjustment components having two limiting plates, the limiting plates being disposed perpendicular to the movement direction of the conveyor belt, and the two limiting plates being disposed opposite the gap between two adjacent conveyor belts.

[0014] In some embodiments, each width adjustment assembly further includes two left and right rotating lead screws, each with a left-handed nut and a right-handed nut. Two limiting plates are respectively installed on the left-handed nut and the right-handed nut. The two left and right rotating lead screws are connected by a belt. One of the left and right rotating lead screws is connected to a third motor. The third motor drives the two left and right rotating lead screws to rotate simultaneously, and the two limiting plates move closer to or further away from each other.

[0015] In some embodiments, an electrical box is also provided on the support frame, located below the conveying section, and a power supply for supplying power is provided inside the electrical box.

[0016] In some embodiments, the electrical box is provided with multiple heat dissipation holes and multiple cooling fans for dissipating heat from the components inside the electrical box.

[0017] This utility model further proposes a box-making machine, which includes the above-mentioned automatic positioning and feeding mechanism.

[0018] This invention proposes an automatic positioning and feeding mechanism. The mechanism uses a conveyor to transport items from the loading port to the unloading port. To ensure the items are neatly arranged inside the packaging box, a positioning block 121 is provided on the conveying path of each item. The position of this positioning block 121 is flexibly adjustable. Its function is to block the items, ensuring that the distance between the heads of each item is exactly the same as the required head-to-head distance within the packaging box. This allows multiple items of different sizes and shapes to be loaded into designated positions within the packaging box at once, thereby improving packaging efficiency. Attached Figure Description

[0030] This application proposes an automatic positioning and feeding mechanism, including a support frame 100, and further comprising: [missing information - likely related to a component mounted on the support frame 100].

[0031] The conveying unit 110 includes multiple conveyor belts 111, with gaps for placing items provided between two adjacent conveyor belts 111, and loading ports 112 and unloading ports 113 respectively provided at both ends of the conveyor belts 111.

[0032] The positioning part 120 is located on the side of the support frame 100 near the discharge port 113, and includes at least one movable positioning block 121. The positioning block 121 can move on the conveyor belt 111 and is used to position the items conveyed on the conveying part 110.

[0033] The limiting part 130 is located above the conveying part 110 and includes at least two limiting plates 131. These two limiting plates 131 can move closer to or further away from each other to limit the items conveyed on the conveying part 110.

[0034] Please see Figures 1 to 5The automatic positioning and feeding mechanism proposed in this application includes a support frame 100 for load-bearing, and a conveying part 110, a positioning part 120 and a limiting part 130 disposed on the support frame 100. The conveying part 110 is used to convey items, the positioning part 120 is used to adjust the position of the conveyed items, and the limiting part 130 is used to prevent items from accidentally falling out of the conveying path during transportation.

[0035] The conveying unit 110 mainly consists of multiple conveyor belts 111, with gaps for placing items between every two adjacent conveyor belts 111. This design is not only flexible, but the number of conveyor belts 111 can be increased or decreased according to actual needs without fixed limitations. When packaging items such as cosmetics, they can be placed in these gaps, effectively preventing the items from tipping over during transport. For ease of understanding, taking cosmetics as an example, one side of a cosmetic product is usually printed with a design, while the other side has product information printed on it. During the packaging process, it is generally required that the side with the design on the cosmetic product face upwards after being placed in the packaging box to ensure overall aesthetics. When packaging cosmetics, they can be placed in these gaps. Especially for items with curved surfaces, such as lipsticks or serum bottles, they can fit well into the gaps. When the conveyor belts 111 on both sides of the gap move synchronously, they will move the cosmetics on the gap together, so that the printed side of the cosmetics always faces up during transportation, which facilitates the subsequent boxing work.

[0036] Specifically, the two ends of these conveyor belts 111 are a loading port 112 and a discharging port 113, respectively. A positioning part 120 is provided on the side of the support frame 100 near the discharging port 113. The positioning part 120 includes multiple positioning blocks 121, and a movable positioning block 121 is provided in the gap between each conveyor belt 111. By adjusting the position of the positioning block 121 in the gap, the distance between the heads of each item can be adjusted. To make it easier to understand, let's take cosmetics as an example again. A set of cosmetics usually contains multiple cosmetics of different sizes, which need to be neatly placed in the same packaging box during packaging. In order to ensure the overall aesthetics, these cosmetics need to be placed in the center of the packaging box. However, because the sizes of each cosmetic are different, their heights from the bottom edge of the packaging box are also different. This difference brings inconvenience to the packaging work, making it difficult to place all cosmetics securely and centrally into the packaging box at once. However, by adjusting the position of the positioning block 121 in the gap, this application can block the cosmetic head that is conveyed to the feeding port 113, thereby ensuring that the distance between each cosmetic head is consistent with the head distance that they need to maintain in the packaging box, so as to facilitate the subsequent boxing work.

[0037] Here, multiple limiting plates 131 are installed above the conveyor section 110. Each pair of limiting plates 131 forms a group, and a corresponding group of limiting plates 131 is installed above each gap used for placing items. The two limiting plates 131 in the same group are positioned on either side of the corresponding gap, and can move closer or further apart. During conveying, the limiting plates 131 block the items on both sides of the gap, further reducing the risk of items accidentally slipping out of the conveying path, in conjunction with the item's engagement with the gap. More importantly, the operator can easily adjust the distance between the two limiting plates 131 according to the size of the item, ensuring that the two limiting plates 131 can limit items of different sizes. This design not only improves the stability of the conveying process but also enhances the overall applicability and flexibility.

[0038] In general, taking cosmetics as an example, multiple cosmetics of different sizes are placed in different slots at the feeding port 112. The number of slots corresponds to the number of individual cosmetics, and the number of positioning blocks 121 corresponds to the number of slots. When the cosmetics are transported to the unloading port 113 via the conveyor belt 111, the cooperation between the slots and the limiting plate 131 ensures that the printed side remains facing upwards. By adjusting the position of the positioning blocks 121, the distance between the heads of each cosmetic can be ensured to match the required head-to-head distance within the packaging box. Above the unloading port 113, a robotic arm can be installed to pick up these arranged cosmetics at once for packaging, allowing multiple cosmetics of different sizes and shapes to be packed into designated positions within the packaging box in one go, saving packaging time and improving packaging efficiency.

[0039] In some embodiments, the conveying unit 110 further includes a first motor 114 and a drive shaft 115. The first motor 114 is connected to the drive shaft 115, and all conveyor belts 111 are connected to the drive shaft 115. The first motor 114 drives the drive shaft 115 to rotate, and all conveyor belts 111 move along with the drive shaft 115 to convey items.

[0040] like Figure 2As shown, in this embodiment, the conveying unit 110 further includes a first motor 114 and a drive shaft 115 connected to each other. The drive shaft 115 and the first motor 114 are arranged on the side of the support frame 100 near the discharge port 113. One end of each conveyor belt 111 is sleeved on the drive shaft 115. A driven shaft is arranged on the side of the support frame 100 near the loading port 112, and the other end of each conveyor belt 111 is sleeved on the driven shaft. When the first motor 114 drives the drive shaft 115 to rotate, all conveyor belts 111 will start moving synchronously with the help of the coordinated action of the drive shaft 115 and the driven shaft. This arrangement ensures that items in the gap between adjacent conveyor belts 111 can be stably transported by the conveyor belts 111 moving at the same speed on both sides, thus ensuring the stability of the transportation process.

[0041] In some embodiments, the positioning part 120 further includes a second motor and a first lead screw 122 connected to each other, and a positioning block 121 is disposed on the first lead screw 122. The second motor drives the first lead screw 122 to rotate, and the positioning block 121 moves on the conveyor belt 111 as the first lead screw 122 rotates.

[0042] In some embodiments, a positioning block 121 is provided in the gap between each pair of adjacent conveyor belts 111, and a positioning block 121 and a second motor are provided on each first lead screw 122, with the first lead screw 122, positioning block 121 and second motor being provided in a one-to-one correspondence.

[0043] like Figure 3 As shown, in this embodiment, a positioning block 121 is provided in the gap between each pair of adjacent conveyor belts 111. Each positioning block 121 is connected to a first lead screw 122, and the number of positioning blocks 121 and first lead screws 122 is the same. Each first lead screw 122 is equipped with a second motor, and the number of first lead screws 122 and second motors is the same. This one-to-one correspondence allows the position of each positioning block 121 to be adjusted, enabling each positioning block 121 to move to a designated position as needed. Specifically, one end of the positioning block 121 is connected to the first lead screw 122, and the other end of the positioning block 121 passes through the gap between the two adjacent conveyor belts 111 to reach above the conveyor belts 111. When the second motor drives the first lead screw 122 to rotate, the first lead screw 122 drives the positioning block 121 to move in the gap along the setting direction of the conveyor belts 111, thereby achieving the effect of positioning items in the gap.

[0044] In some embodiments, the positioning part 120 further includes a distance sensor, which is disposed at one end of the support frame 100 near the discharge port 113, for detecting the distance between the positioning block 121 and the distance sensor.

[0045] In this embodiment, a distance sensor is provided at one end of the support frame 100 near the unloading port 113. This distance sensor is fixedly mounted on the support frame 100 and serves as the coordinate origin for recording the movement of the positioning block 121. In actual use, when multiple products of different sizes need to be packed into a packaging box, the distance between the head of each product and the bottom edge of the packaging box is first measured. The measured value is then used as the movement distance between the positioning block 121 and the distance sensor. The second motor controls the corresponding positioning block 121 to move this distance, and this operation is repeated to ensure that each positioning block 121 moves to the designated position. The setting of the distance sensor improves the positioning accuracy and operational reliability. Next, these precisely positioned positioning blocks 121 block the items conveyed from the loading port 112 to the unloading port 113, ensuring that the distance between the heads of each item conveyed to the unloading port 113 is exactly the same as the head distance they need to maintain in the packaging box, thus ensuring the smooth progress of subsequent boxing operations.

[0046] In some embodiments, the limiting part 130 includes a mounting frame 132 disposed on the support frame 100. The mounting frame 132 is located above the conveying part 110. At least one set of width adjustment components is disposed on the mounting frame 132. Each set of width adjustment components has two limiting plates 131. The limiting plates 131 are disposed perpendicular to the movement direction of the conveyor belt 111, and the two limiting plates 131 are disposed facing the gap between two adjacent conveyor belts 111.

[0047] In some embodiments, each width adjustment assembly further includes two left-hand and right-hand screws 133, each of which is provided with a left-hand nut and a right-hand nut. Two limiting plates 131 are respectively installed on the left-hand nut and the right-hand nut. The two left-hand and right-hand screws 133 are connected by a belt. One of the left-hand and right-hand screws 133 is connected to a third motor 134. The third motor 134 drives the two left-hand and right-hand screws 133 to rotate simultaneously, and the two limiting plates 131 move closer to or further away from each other accordingly.

[0048] like Figure 4As shown, in this embodiment, the limiting part 130 includes a mounting frame 132 and a width adjustment assembly. The mounting frame 132 is disposed above the conveying part 110, and the width adjustment assembly is mounted on the mounting frame 132. Each set of width adjustment assemblies has two limiting plates 131, two left-hand and right-hand screws 133, and a third motor 134. Specifically, each left-hand and right-hand screw 133 is provided with a left-hand nut and a right-hand nut. Since each left-hand and right-hand screw 133 is provided with two sets of threads with opposite rotation directions, these two sets of threads are used to connect the left-hand nut and the right-hand nut respectively. When the left-hand and right-hand screws 133 rotate, the left-hand nut and the right-hand nut move along different threads, thereby moving closer to each other or separating from each other. The two left-hand and right-hand screws 133 are connected together by a belt, and one of the left-hand and right-hand screws 133 is connected to a third motor 134. Each width adjustment assembly has two limiting plates 131. One limiting plate 131 is connected to two left-handed nuts, and the other limiting plate 131 is connected to two right-handed nuts. The limiting plates 131 are set perpendicular to the movement direction of the conveyor belt 111. When the third motor 134 drives one of the connected left-handed and right-handed lead screws 133 to rotate, the other left-handed and right-handed lead screw 133 will rotate together under the cooperative action of the belt, causing the two limiting plates 131 to move closer or further apart. The number of width adjustment assemblies can be increased or decreased according to actual needs. Specifically, a width adjustment assembly is set above each gap used for placing items. By adjusting the distance between the two limiting plates 131, items of different sizes are limited to ensure that the items do not shift during transportation.

[0049] In other embodiments, such as Figure 5 As shown, a transparent cover plate 135 is installed on the top of the mounting frame 132, and protective covers 136 are installed on both sides of the mounting frame 132. The transparent cover plate 135 protects the items during transport from external dust and other impurities; its transparency allows operators to clearly observe the real-time status of the items during transport, facilitating monitoring and management. The protective covers 136 effectively isolate potential interference from external factors to the third motor 134, ensuring the stability and reliability of motor operation. The protective covers 136 also prevent accidental contact with the operating third motor 134, reducing the safety risks caused by accidental contact and ensuring operator safety.

[0050] In some embodiments, an electrical box 140 is also provided on the support frame 100. The electrical box 140 is located below the conveying section 110, and a power supply for power supply is provided inside the electrical box 140.

[0051] In some embodiments, the electrical box 140 is provided with a plurality of heat dissipation holes 141 and a plurality of cooling fans 142 for dissipating heat from the components inside the electrical box 140.

[0052] like Figure 1 As shown, in this embodiment, an electrical box 140 is also provided below the conveying section 110. The electrical box 140 is fixedly mounted on the support frame 100, and the interior of the electrical box 140 is used to house power supply components. Multiple heat dissipation holes 141 are also provided through the outer shell of the electrical box 140 for heat dissipation of the interior of the electrical box 140. Multiple cooling fans 142 are also installed on the electrical box 140 to enhance air convection and thus improve heat dissipation efficiency.

[0053] This utility model further proposes a box-making machine, which includes the above-mentioned automatic positioning and feeding mechanism. The specific structure of the automatic feeding mechanism is as described in the above embodiments. Since the box-making machine adopts all the technical solutions of all the above embodiments, it has at least all the technical effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0054] In summary, this utility model proposes an automatic positioning and feeding mechanism. The conveyor unit 110 transports items from the feeding port 112 to the unloading port 113. To ensure the items are aesthetically arranged within the packaging box, when the items are transported to the unloading port 113 by the conveyor belt 111, the printed side is kept facing upwards by the cooperation of the gap and the limiting plate 131. Furthermore, a positioning block 121 is provided on the conveying path of each item. The position of this positioning block 121 is flexibly adjustable and its function is to block the items, ensuring that the distance between the heads of each item is exactly the same as the required head-to-head distance within the packaging box. This allows multiple items of different sizes and shapes to be loaded into designated positions within the packaging box at once, thereby improving packaging efficiency.
