[0049] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0050] As shown in Figure 1-20, an automatic material loading system for a vacuum freeze-drying equipment includes a first conveyor belt, a second conveyor belt, a material container 500, a material transport vehicle 100, and a track 400. The first conveyor belt and the second conveyor belt 300 are used to transport materials. The material container 500 is used to receive the materials transported by the first conveyor belt. The material transport vehicle 100 is used to transport the material container 500 containing materials. Specifically, the first conveyor belt 200 is used to transport the material container 500 containing materials to the material transport vehicle, and the second conveyor belt 300 is used to transport the material container 500 containing materials out of the material transport vehicle. The second conveyor belt 300 is located on one side of the first conveyor belt 200. The material transport vehicle 100 is a track 400 vehicle, and the track 400 controls the movement direction of the material transport vehicle 100.

[0051] The material conveyor 100 includes a loading platform 101, several partitions 102, and a hydraulic cylinder 105. The loading platform 101 is configured to have a platform for placing the material box 500. The loading platform 101 is placed on the track 400. The partitions 102 are provided on the loading platform 101. The bottom of the loading platform 101 is provided with a mounting block, and the hydraulic cylinder 105 is provided on the mounting block. After the material box 500 moves to the first partition 102, the hydraulic cylinder 105 pushes the first partition 102 to rise relative to the loading platform 101. The second partition 102 moves to below the first partition 102 to form a material cavity for placing the material box 500.

[0052] During the loading process, the conveyor 100 moves to one side of the first conveyor belt. The first conveyor belt transports the material-filled container 500 onto the conveyor 100. At this time, the conveyor 100 only has one partition 102. After the material container 500 is loaded onto the partition 102, the hydraulic cylinder 105 pushes the partition 102 on the loading platform 101 upwards. Another partition 102 moves from the other side of the conveyor 100 to the loading platform 101. The newly moved partition 102 on the loading platform 101 moves to below the partition 102 that was originally on the loading platform 101. The partition 102 on the loading platform 101 and the partition 102 originally on the loading platform 101 cooperate to form a loading cavity. The loading cavity is level with the first conveyor belt. The first conveyor belt continues to transport the new loading box 500 towards the conveyor 100. The new loading plate moves into the loading cavity. Then, the hydraulic cylinder 105 pushes all the partitions 102 on the loading platform 101 to rise again. A new partition 102 moves back onto the loading platform 101. This continues until the partitions 102 on the loading platform 101 reach the specified height. Then, the conveyor 100 drives the loading box 500 to move to the second conveyor belt.

[0053] By continuously placing the partition 102 onto the loading platform 101, the position of the loading chamber is always aligned with the first conveyor belt. No additional lifting or gripping devices are needed, making the entire system more compact and reducing the space occupied by the system, making it suitable for small-scale production. After the first conveyor belt delivers the loading box 500 to the break point, it directly transports the loading box 500 onto the loading platform 101 without any other unnecessary actions, improving the tray loading efficiency and meeting production needs.

[0054] The bottom of the partition 102 is provided with a slider 120, and the loading platform 101 is provided with a groove corresponding to the slider 120. The bottom of the partition 102 is provided with a second movable groove for the slider 120 to move. One end of the slider 120 is provided with a second return spring 1201. The bottom of the partition 102 is also provided with a first movable groove, which is located on one side of the second movable groove. A first limiting block 121 is provided in the first movable groove. The first limiting block 121 is connected to the first movable groove by a first connecting spring. The loading platform 101 is provided with a first limiting groove corresponding to the first limiting block 121. The side wall of the second movable groove is provided with a first movable cavity communicating with the first movable groove. The slider 120 is provided with a limiting plate 122. The first limiting block 121 is provided with a second limiting groove corresponding to the limiting plate 122. When the slider 120 is at one end of the second movable groove, the limiting plate 122 passes through the first movable groove.

[0055] The partition 102 is pushed onto the loading platform 101 by a horizontal push. After the hydraulic cylinder 105 pushes the partition 102 on the loading platform 101 to rise, the new partition 102 moves onto the loading platform 101. The slider 120 moves in the slide groove. After the slider 120 moves to one end of the slide groove, the partition 102 continues to move relative to the loading platform 101. The slider 120 moves in the second movable groove. The limiting plate 122 moves relative to the first limiting block 121. The limiting plate 122 moves out of the second limiting groove and is located at one end of the first movable cavity. The first connecting spring pushes the first limiting block 121 to move downward. When the first limiting block 121 moves to the top of the first limiting groove, the first limiting block 121 is directly inserted into the first limiting groove. The cooperation of the first limiting block 121 and the slider 120 fixes the partition 102, preventing the partition 102 from moving relative to the loading platform 101 when the loading box 500 moves onto the partition 102.

[0056] The bottom of the partition 102 has a groove, and a second push plate 106 is installed in the groove. The second push plate 106 is connected to the groove by a third connecting spring 1061. The first limiting block 121 is connected to the second push plate 106 by a connecting rod 1062. The partition 102 has a first slot, and the second push plate 106 has a second slot corresponding to the first slot. One end of the second slot has a ninth movable slot, and a fourth connecting spring 1071 is installed in the ninth movable slot. One end of the fourth connecting spring 1071 has a movable plate 107, and the movable plate 107 has a through hole corresponding to the piston rod of the hydraulic cylinder 105. The side wall of the through hole has a... The piston rod of cylinder 105 has a corresponding third slot; the piston rod of hydraulic cylinder 105 is provided with a tenth movable slot and an eleventh movable slot. The tenth movable slot is provided with a first electromagnet, a fifth connecting spring 1231 and a support block 123. The support block 123 is connected to the tenth movable slot through the fifth connecting spring 1231 and is made of ferromagnetic material. The eleventh movable slot is located below the tenth movable slot. The eleventh movable slot is provided with a second electromagnet, a sixth connecting spring 1241 and a third push block 124. The third push block 124 is connected to the eleventh movable slot through the sixth connecting spring 1241 and is made of magnet.

[0057] By utilizing the first and second slots, the movement of the other partition 102 is prevented from being obstructed when the hydraulic cylinder 105 raises the partition 102 on the loading platform 101. When the partition 102 moves onto the loading platform 101, one end of the movable plate 107 abuts against the piston rod of the hydraulic cylinder 105, and the movable plate 107 moves into the ninth movable slot to ensure the normal movement of the partition 102. After the first limiting block 121 on the newly moved partition 102 on the loading platform 101 is inserted into the first limiting slot on the loading platform 101, the hydraulic cylinder 105 drives the piston rod to move back. After the movable plate 107 loses its thrust, it extends out from the ninth movable slot, and the through hole moves above the piston rod of the hydraulic cylinder 105.

[0058] When the material conveyor 100 is at one end of the first material conveyor belt 200, the first electromagnet and the second electromagnet are continuously de-energized, the support block 123 is extended from the tenth movable groove, and the third push block 124 is in the eleventh movable groove. When the hydraulic cylinder 105 drives the piston rod to move upward, the support block 123 abuts against the bottom of the movable plate 107. The support block 123 first pushes the second push plate 106 relative to the partition plate 102 to move towards the top of the groove. The second push plate 106 drives the first limiting block 121 to move into the first movable groove together. The first limiting block 121 moves out of the first limiting groove and enters the first movable groove. After the second push plate 106 moves to the top of the groove, it drives the partition plate 102 to move together. After the partition plate 102 rises from the loading platform 101, the second reset spring 1201 pushes the slider 120 to move in the second movable groove. When the limiting plate 122 moves with the slider 120, it is reinserted into the second limiting groove to fix the first limiting block 121.

[0059] The new partition 102 moves onto the loading platform 101, forming a new loading cavity. When the conveyor 100 is at one end of the second conveyor belt 300, after the loading box 500 on the partition 102, which is level with the second conveyor belt 300, moves off the partition 102, both the first and second electromagnets are energized. The first electromagnet attracts the support block 123 into the tenth movable slot, and the second electromagnet pushes the third push block 124 to move out of the eleventh movable slot. The hydraulic cylinder 105 drives the piston rod to extend upward, and the top of the piston rod of the hydraulic cylinder 105 directly enters the through hole on the bottom partition 102. After passing through, the first electromagnet is de-energized, and the support block 123 extends out from the tenth movable slot. The hydraulic cylinder 105 drives the piston rod to continue moving upward. The support block 123 abuts against the bottom surface of the movable plate 107 on the second partition 102 from the bottom up, pushing the partition 102 to move upward. At this time, the third push block 124 abuts against the movable plate 107 on the bottom partition 102. When the second push plate 106 moves, it drives the first limit block 121 to move together. The bottom partition 102 does not rise from the loading platform 101. At this time, the bottom partition 102 can be directly pulled out from the loading platform 101.

[0060] After the bottom partition 102 is removed from the loading platform 101, the hydraulic cylinder 105 drives the piston rod to move downward. The lifted partition 102 moves downward along with the piston rod, so that the partition 102 containing the material box 500 moves again to one end of the second conveyor belt 300. Without the need for additional lifting devices and gripper devices, all the material boxes 500 on the conveyor trolley 100 can be transported to the second conveyor belt 300, meeting the production needs of small-site factories.

[0061] The partition 102 is provided with a baffle 1021, the top of the baffle 1021 is provided with a first protrusion 1022, the first protrusion 1022 is provided with a third movable groove, the baffle 1021 is provided with a fourth movable groove, the third movable groove is provided with a second limiting block 109, the second limiting block 109 is connected to the third movable groove by a seventh connecting spring 1091, and the second limiting block 109 is provided with an inclined surface; the fourth movable groove is provided with a first push block 108, the first push block 108 is connected to the fourth movable groove by an eighth connecting spring 1081;

[0062] The material container 500 has a fourth slot on its side wall, a fifth movable slot at the bottom of the fourth slot, a movable rod 501 inside the fifth movable slot, a first support spring 5011 at the bottom of the movable rod 501, and a first push plate 5012 at the top of the movable rod 501. When the material container 500 moves to the partition 102, the fourth slot is below the third movable slot. The baffle 1021 has a seventh movable slot, a third push plate 111 inside the seventh movable slot, and the third push plate 111 is above the first push plate 5012.

The second push rod 113 passes through the transmission cavity. A first transmission rod 1082 and a transmission wheel 112 connected to the first push block 108 are provided in the transmission cavity. The transmission wheel 112 is used to drive the first transmission rod 1082 and the second push rod 113.

[0064] The second movable cavity is also provided with a fourth movable cavity at one end. The fourth movable cavity is located on one side of the third movable cavity. The first push rod 114 is provided with a third transmission rod 1141 at one end. The third transmission rod 1141 passes through the fourth movable cavity. The partition plate 102 is provided with a connecting cavity that connects the fourth movable cavity and the seventh movable groove.

The connecting cavity is provided with a transmission roller 118 for driving the second transmission rod 1111 and the third transmission rod 1141.

[0065] The bottom of the third movable cavity is provided with an eighth movable groove and a twelfth movable groove. The eighth movable groove is provided with a third limiting block 115, and the twelfth movable groove is provided with a second push block 116. The eighth movable groove and the twelfth movable groove are connected. The third limiting block 115 and the second push block 116 are connected by a connecting plate 117. The bottom of the connecting plate 117 is provided with a second support spring 1171. The third limiting block 115 and the second push block 116 are respectively provided with a first inclined surface and a second inclined surface. The first inclined surface and the second inclined surface are inclined in opposite directions. The second push rod 113 is provided with a second protrusion 1132.

[0066] When the material container 500 moves onto the partition 102, the first push plate 5012 abuts against the inclined surface of the second limiting block 109, pushing the second limiting block 109 into the third movable groove. When the material container 500 abuts against the side wall of the baffle 1021, the second limiting block 109 extends out of the third movable groove again, abutting against the first push plate 5012 to fix the material container 500.
