Description

Technical Field

[0001] This utility model relates to the field of packing equipment, and more specifically, to a loading machine and a material packing system. Background Technology

[0002] Traditional material packing methods typically involve directly conveying the materials into the packaging box.

[0003] However, in the existing technology, there is a height difference between the discharge port of the conveyor and the bottom wall of the box, which causes the material to collide with the material inside the box during the process of entering the box, resulting in damage to the material. Utility Model Content

[0018] In an optional embodiment, the loading machine further includes a drive wheel, a driven wheel, and a third transmission belt; the third transmission belt is used to move the inner liner between the loading position and the unloading position.

[0019] The third transmission belt is installed on both the driving pulley and the driven pulley; both the driving pulley and the driven pulley are installed on the frame, and the third transmission belt is connected to the outer wall of the inner liner.

[0020] In an optional embodiment, the loading machine further includes a connector that is connected to the third drive belt and the outer wall of the inner liner.

[0022] Secondly, this utility model provides a material packing system, comprising:

[0023] The first conveying device, the second conveying device, and the aforementioned loading machine are configured such that the first conveying device is used to convey materials and the second conveying device is used to convey the box body; both the first conveying device and the second conveying device are mounted on the frame.

[0024] When the inner liner moves from the loading position to the unloading position, the first shielding component is used to close part of the first opening located below the first conveying device;

[0025] When the inner liner is in the feeding position, the material is moved into the inner liner by the first conveying device through the first opening; when the inner liner is in the unloading position, the material is moved into the box body through the second opening.

The second shielding assembly is connected to the inner liner and is used to close or open the second opening.

[0028] When the inner liner is in the loading position, material enters the inner liner through the first opening. As the inner liner moves downwards from the loading position to the unloading position, the first blocking component closes at least a portion of the first opening, meaning the open portion of the first opening gradually decreases. Material is continuously conveyed into the inner liner through the open portion of the first opening. When the inner liner is in the unloading position, the first conveying device stops transporting, and the blocking component opens the second opening, allowing the material inside the inner liner to be released into the box through the second opening. This achieves material separation and reduces the height difference between the material and the bottom of the box during the material packing process, thereby reducing the material damage rate.

The first conveying device is used to convey materials, and the second conveying device is used to convey the box body. Both the first and second conveying devices are mounted on a frame. When the inner liner moves from the loading position to the unloading position, a first blocking component is used to close a portion of the first opening located below the first conveying device. When the inner liner is in the loading position, materials move from the first conveying device into the inner liner through the first opening. When the inner liner is in the unloading position, materials move from the inner liner into the box body through the second opening. This material packing system includes all the beneficial effects of the aforementioned loading machine. Attached Figure Description

[0051] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the material packing system 400 provided in an embodiment of the present utility model.

[0052] The material packing system 400 includes a first conveying device 200, a second conveying device 300, and a loading machine 100. The first conveying device 200 is used to convey materials, and the second conveying device 300 is used to convey boxes. Both the first conveying device 200 and the second conveying device 300 are mounted on a frame 110. The first conveying device 200 transports materials to the loading machine 100, and the loading machine 100 then transports the materials to the boxes located on the second conveying device 300.

[0053] The following is a detailed description of the loading machine 100:

[0054] Please refer to Figures 1-4 , Figure 2 This is a structural schematic diagram of the loading machine 100 from a first-view perspective provided in an embodiment of the present utility model; Figure 3 This is a structural schematic diagram of the loading machine 100 provided in an embodiment of the present utility model from a second perspective. Figure 4A schematic diagram of the inner liner 120 provided in this embodiment of the utility model.

[0055] The loading machine 100 includes a frame 110, an inner liner 120, a first shielding assembly 130, and a second shielding assembly 140. The inner liner 120 is movably mounted on the frame 110 and has a loading position and a unloading position, with the loading position located above the unloading position. The inner liner 120 has a first opening 121 and a second opening 122. The first opening 121 is located on the side wall of the inner liner 120, while the second opening 122 is located on the bottom wall of the inner liner 120.

[0056] When the inner liner 120 is in the feeding position, the material enters the inner liner 120 through the first opening 121. At this time, the discharge port of the first conveying device 200 is flush with the bottom of the inner liner 120, thereby reducing the height difference between the material and the bottom of the inner liner 120, and thus reducing the damage rate of the material.

[0057] Understandably, as the inner liner 120 moves downward from the loading position to the unloading position, the first conveying device 200 moves upward relative to the first opening 121; the portion of the first opening 121 above the first conveying device 200 gradually decreases as the inner liner 120 moves downward. It should be noted that during the downward movement of the inner liner 120, material is continuously conveyed into the inner liner 120 through the portion of the first opening 121 above the first conveying device 200.

[0058] When the inner liner 120 is in the unloading position, the first conveying device 200 stops transporting, and the first shielding assembly 130 closes the portion of the first opening 121 located below the first conveying device 200. A portion of the second shielding assembly 140 enters the box, contacting the bottom of the box. Subsequently, the second shielding assembly 140 opens the second opening 122, allowing the material inside the inner liner 120 to be released into the box through the second opening 122, thus achieving material separation. Furthermore, during the material loading process, the height difference between the material and the bottom of the box is reduced, thereby lowering the material damage rate.

[0059] It should be noted that the materials packed by the material packing system 400 can be fruits, vegetables, or other items that are easily damaged by collision. In this embodiment, the material packing system 400 is used to pack fruits.

[0060] Further, please refer to Figures 1-5 , Figure 5 for Figure 2A partial enlarged view at point A. The first shielding assembly 130 includes a first transmission belt 131, a counterweight roller 132, and a positioning shaft 133; the positioning shaft 133 is located on the side where the first opening 121 is located, and the positioning shaft 133 is connected to the frame 110. It should be noted that during the movement of the inner liner 120, the portion of the first opening 121 located below the first conveying device 200 is also located below the positioning shaft 133; the portion of the first opening 121 located above the first conveying device 200 is also located above the positioning shaft 133.

[0061] Understandably, as the inner liner 120 moves downward, the positioning shaft 133 moves upward relative to the first opening 121, and the portion of the first opening above the positioning shaft 133 gradually becomes smaller.

[0062] Furthermore, during the movement process, the fruit is continuously conveyed into the inner liner 120 through the first opening 121 located above the positioning shaft 133, thereby realizing the separation of the fruit into boxes.

[0063] Please refer to Figures 1-5 One end of the first drive belt 131 is connected to the bottom wall of the inner liner 120, allowing the inner liner 120 to drive the first drive belt 131 downward. Since the first drive belt 131 is wound around the positioning shaft 133, the positioning shaft 133 can act as a guide, so that during the movement of the inner liner 120, part of the first drive belt 131 can close the part of the first opening 121 located below the positioning shaft 133; thereby preventing the fruit from falling out of the part of the first opening 121 located below the positioning shaft 133 and reducing the damage rate of the fruit.

[0064] It should be noted that in this embodiment, the first transmission belt 131 is a belt, which is elastic, so that the fruit inside the inner liner 120 and the first transmission belt 131 make flexible contact, thereby reducing the damage rate of the fruit.

[0065] In this embodiment, the other end of the first transmission belt 131 is connected to the counterweight roller 132, and a portion of the first transmission belt 131 is wound around the counterweight roller 132; the counterweight roller 132 is movably connected to the frame 110; thereby extending the length of the first transmission belt 131 and preventing the first transmission belt 131 from failing to close the first opening 121 located below the positioning shaft 133 due to length limitations. Furthermore, the loading machine 100 uses a configuration roller to balance the weight at both ends of the first transmission belt 131, preventing weightlessness.

[0066] According to the above configuration, the first shielding component 130 is further provided with a first guide rail 134, which is connected to the frame 110 and movably connected to the counterweight roller 132. Specifically, during the movement of the inner liner 120, the counterweight roller rolls relative to the first guide rail 134, thereby releasing more of the first transmission belt 131 so that the first transmission belt 131 can close the portion of the first opening 121 located below the positioning shaft 133. After the first transmission belt 131 wound around the counterweight roller 132 is completely released, the inner liner 120 continues to move, driving the counterweight roller 132 to slide on the first guide rail 134, thereby increasing the length of the first transmission belt 131 that can be used to close the first opening 121. In this embodiment, the first guide rail 134 is inclined so that the counterweight roller 132 moves obliquely upward, thereby balancing the weight at both ends of the first transmission belt 131 and avoiding weightlessness.

[0067] Please refer to Figures 1-8 , Figure 6 A schematic diagram of the structure of the inner liner 120 and the first shielding component 130 when the inner liner 120 is in the feeding position according to an embodiment of the present utility model; Figure 7 This is a schematic diagram of the structure of the first shielding component 130 provided in an embodiment of the present utility model; Figure 8 This utility model provides a schematic diagram of the structure of the inner liner 120 and the first shielding component 130 when the inner liner 120 is in the unloading position.

[0068] Furthermore, the second shielding assembly 140 includes a second transmission belt 141, a rocker arm 142, and a rotating shaft 143; at least a portion of the second transmission belt 141 covers the outer wall of the inner liner 120; both ends of the second transmission belt 141 are respectively connected to both ends of the rocker arm 142; the rocker arm 142 and the outer wall of the inner liner 120 are movably connected. Understandably, the rocker arm 142 rotates to drive the second transmission belt 141 to slide on the outer surface of the inner liner 120, thereby closing or opening the second opening 122. Specifically, when the inner liner 120 is in the unloading position, the second transmission belt 141 contacts the bottom of the box, thereby opening the second opening 122, reducing the height difference between the fruit and the bottom of the box when packing fruit, thus reducing the fruit damage rate.

[0069] It should be noted that in this embodiment, the second transmission belt 141 is a belt with a certain degree of elasticity to achieve flexible contact between the fruit and the belt, thereby reducing the damage rate of the fruit.

[0070] In this embodiment, the end of the rocker arm 142 rotates clockwise, allowing the second transmission belt 141 to slide to the bottom wall of the inner liner 120, thereby closing the second opening 122. The end of the rocker arm 142 rotates counterclockwise, allowing the second transmission belt 141 to slide away from the bottom wall of the inner liner 120, thereby opening the second opening 122. In other embodiments, the rotation direction of the rocker arm 142 can be changed; for example, when the rocker arm 142 rotates counterclockwise, the second transmission belt 141 closes the second opening 122.

[0071] According to the above structural configuration, in this embodiment, the rotating shaft 143 is located between the two ends of the rocker arm 142, and the end of the rocker arm 142 rotates around the rotating shaft 143; the rotating shaft 143 is movably connected to the rocker arm 142, and the rotating shaft 143 is connected to the outer wall of the inner liner 120. Understandably, the rocker arm 142 drives the second transmission belt 141 to rotate around the rotating shaft 143, so that the second transmission belt 141 can close or open the second opening 122. Specifically, in this embodiment, the rotating shaft 143 is connected to the middle of the rocker arm 142, so that the displacement distances of the two ends of the rocker arm 142 are the same, so that during the rotation of the rocker arm 142, it will not be affected by the frame 110 located on both sides of the inner liner 120. Furthermore, the second transmission belt 141 can close the second opening 122, preventing the fruit from falling through the second opening 122 when there is a large height difference between the fruit and the box, thus reducing the fruit damage rate.

[0072] Further, please refer to Figures 1-8 The second shielding assembly 140 also includes a guide shaft 144, which is disposed on the outer wall of the inner liner 120. The second transmission belt 141 is wound around the guide shaft 144. In this embodiment, two mounting seats 145 are provided, and the two ends of the guide shaft 144 are rotatably connected to the two mounting seats 145 respectively. The mounting seats 145 are disposed on the outer wall of the inner liner 120. The second transmission belt 141 moves along the outer wall of the inner liner 120 during rotation using the guide shaft 144, thereby closing or opening the second opening 122. Thus, by providing the guide shaft 144, the contact surface between the second transmission belt 141 and other structures is reduced, thereby reducing the wear of the second transmission belt 141 and increasing its service life.

[0073] Based on the above, in this embodiment, the second shielding assembly 140 further includes a cylinder 146, which drives the end of the rocker arm 142 to rotate around the rotating shaft 143. Both ends of the cylinder 146 are movably connected to the rocker arm 142 and the outer wall of the inner liner 120, respectively. The loading machine 100, through the extension and retraction of the cylinder 146, drives the rocker arm 142 to rotate, thereby moving the second transmission belt 141 to close or open the second opening 122, preventing fruit from falling through the second opening 122 when there is a significant height difference between the fruit and the box, thus reducing the fruit damage rate.

[0074] Further, please refer to Figures 1-10 , Figure 9 A schematic diagram of the structure of the inner liner 120 and the lifting assembly 150 provided in this embodiment of the utility model; Figure 10 A schematic diagram of the lifting assembly 150 provided in this embodiment of the present utility model.

[0075] The loading machine 100 also includes a lifting assembly 150, which includes a driving wheel 151, a driven wheel 152, and a third transmission belt 153. The third transmission belt 153 is used to drive the inner liner 120 to move between the loading position and the unloading position. The third transmission belt 153 is disposed between the driving wheel 151 and the driven wheel 152. Both the driving wheel 151 and the driven wheel 152 are disposed on the frame 110, and the inner liner 120 is located between the driving wheel 151 and the driven wheel 152. The third transmission belt 153 is connected to the outer wall of the inner liner 120. Specifically, the driving wheel 151 rotates, driving the third wheel to move, thereby driving the inner liner 120 to move vertically, that is, between the loading position and the unloading position. In this embodiment, the third transmission belt 153 is a rack and pinion, and both the driving wheel 151 and the driven wheel 152 are gears, which has a simple structure and low cost.

[0076] In this embodiment, the lifting assembly 150 further includes a first motor 155 and a connecting member 154. The first motor 155 drives the drive wheel 151 to rotate. The loading machine 100 uses the first motor 155 to drive the drive wheel 151 to rotate, thereby moving the inner liner 120 vertically to automate the device and save manpower. The connecting member 154 is connected to the third transmission belt 153 and the outer wall of the inner liner 120. The loading machine 100 uses the connecting member 154 to improve the stability of the connection between the inner liner 120 and the third transmission belt 153.

[0077] Further, please refer to Figures 1-11 , Figure 11 for Figure 2 A partial enlarged view at point B. The loading machine 100 also includes a sliding assembly 160, which includes a second guide rail 161 and a slider 162. The second guide rail 161 is located between the driving wheel 151 and the driven wheel 152, and is mounted on the frame 110. The second guide rail 161 and the slider 162 are slidably connected, and the slider 162 is connected to the side wall of the inner liner 120. Thus, the second guide rail 161 and the slider 162 assist the inner liner 120 in moving vertically, preventing the inner liner 120 from shifting and improving structural stability.

[0078] In this embodiment, please refer to Figures 1-3The loading machine 100 also includes a first sensor 170, a second sensor 180, and a third sensor 190. The first sensor 170 and the second sensor 180 are located on the side of the inner liner 120 and connected to the frame 110, used to detect the position of the inner liner 120. Specifically, the first sensor 170 is located above the second sensor 180. When the first sensor 170 detects that the inner liner 120 is in the loading position, the first conveying device 200 begins to convey fruit into the inner liner 120. At this time, the second opening 122 is located above the positioning shaft 133, the first transmission belt 131 opens the first opening 121, and the second transmission belt 141 closes the second opening 122. When the second sensor 180 detects that the inner liner 120 is in the unloading position, the first conveyor 200 stops conveying, the second drive belt 141 contacts the bottom of the box, and the second drive belt 141 moves to open the second opening 122, releasing the fruit into the box, thus completing the sorting of the fruit. This reduces the height difference between the fruit and the bottom of the box during packing, thereby reducing the fruit damage rate. Thus, by detecting the position of the inner liner 120 through the first sensor 170 and the second sensor 180 and transmitting the detected signals to the control terminal, the control terminal can precisely control the movement of the first conveyor 200, the second conveyor 300, the second shielding assembly 140, and the lifting assembly 150, thereby reducing the height difference between the fruit and the bottom of the box during packing, and thus reducing the fruit damage rate.

[0079] The third sensor 190 is located at the top of the inner liner 120 to detect the height of the fruit inside the inner liner 120 and transmits the detected signal to the control terminal to control the lifting speed of the lifting assembly 150. This ensures that the upper surface formed by the stacked fruit in the inner liner 120 is always flush with the delivery port of the first conveying device 200, avoiding a height difference between the delivery port and the fruit in the inner liner 120, thereby reducing the fruit damage rate.

[0080] Further, please refer to Figures 1-13 , Figure 12 A schematic diagram of the structure of the first conveying device 200 provided in this embodiment of the utility model; Figure 13 This is a schematic diagram of the structure of the second conveying device 300 provided in an embodiment of the present utility model.

[0081] In this embodiment, the first conveying device 200 includes a second motor 210, a fruit and vegetable conveyor belt 220, and a guide plate 230. The second motor 210 drives the fruit and vegetable conveyor belt to move, thereby conveying fruit. The guide plate 230 is located at the delivery port of the first conveying device 200, and is used to allow the fruit on the fruit and vegetable conveyor belt 220 to smoothly enter the inner liner 120. The second conveying device 300 includes a third motor 310, a box conveyor belt 320, and a baffle 330. The third motor 310 drives the box conveyor belt 320 to move the box. The baffle 330 is located above the box conveyor belt 320. When the box is directly facing the second opening 122, the baffle 330 restricts the movement of the box, allowing the fruit in the inner liner 120 to be placed inside the box.

[0082] In summary, when the inner liner 120 is in the loading position, the fruit enters the inner liner 120 through the first opening 121. At this time, the discharge port of the first conveying device 200 is flush with the bottom of the inner liner 120, thereby reducing the height difference between the fruit and the bottom of the inner liner 120 and thus reducing the fruit damage rate. As the inner liner 120 moves downwards from the loading position to the unloading position, the first conveying device 200 moves upwards relative to the first opening 121; the portion of the first opening 121 above the first conveying device 200 gradually decreases as the inner liner 120 moves downwards. Furthermore, the fruit is continuously conveyed into the inner liner 120 through the portion of the first opening 121 above the first conveying device 200. When the inner liner 120 is in the unloading position, the first conveying device 200 stops transporting, and the first blocking component 130 closes the portion of the first opening 121 below the first conveying device 200. Part of the second shielding component 140 enters the interior of the box, and the second shielding component 140 contacts the bottom of the box. Then, the second shielding component 140 opens the second opening 122, and the fruit located in the inner liner 120 is released into the box through the second opening 122, thereby realizing the separation of the fruit into boxes. In addition, during the fruit packing process, the height difference between the fruit and the bottom of the box is reduced, thereby reducing the damage rate of the fruit.

[0083] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
