[0033] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0034] The terms “left,” “right,” “front,” “back,” “up,” and “down” mentioned in the following description are oriented in the viewing direction of the front view.

[0035] Example 1

[0036] In some embodiments, please refer to the appendix of the specification. Figure 1-5A material lifting mechanism includes a mounting assembly 1, a drive assembly 2 mounted on the upper right side of the mounting assembly 1, and lifting assemblies 3 mounted on both sides of the mounting assembly 1 for lifting material assembly assemblies 6. A detection and control assembly 5 is mounted on the inner side wall of the mounting assembly 1 to detect the use status and lifting height of the material assembly 6.

[0037] The lifting assembly 3 includes a sprocket assembly 31 , a transmission shaft 32 , a bearing 33 and a fixing block 34 .

[0038] A drive shaft 32 is rotatably mounted at the top of the mounting assembly 1, and is positioned horizontally. Two sets of bearings 33 are rotatably connected to each end of the drive shaft 32, and the bearings 33 are connected to the mounting assembly 1. Two sets of sprocket assemblies 31 are positioned at the left and right ends of the mounting assembly 1, respectively. The two sets of sprocket assemblies 31 are connected to the ends of the drive shaft 32, and the sprocket assemblies 31 are connected to the mounting assembly 1. The drive shaft 32 drives the two sets of sprocket assemblies 31 to operate synchronously.

[0039] There are two sets of fixed blocks 34, which are respectively installed on the sprocket assemblies 31 on both sides. The height of the two sets of fixed blocks 34 is consistent. The fixed blocks 34 and the corresponding sprocket assemblies 31 operate synchronously, and the two ends of the material to be lifted are respectively used to engage with the fixed blocks 34.

[0040] When the present invention is used, the driving assembly 2 is started to drive the transmission shaft 32 to run on the bearing 33 , the transmission shaft 32 drives the two sets of sprocket assemblies 31 to move synchronously, and the sprocket assemblies 31 drive the fixed block 34 to lift the material assembly assembly 6 .

[0041] When manually controlling the fixed block 34, if it reaches the area located above or below the detection and control assembly 5, the detection and control assembly 5 will control the drive assembly 2 to power off. This arrangement prevents the fixed block 34 from exceeding its travel range, protecting the material assembly assembly 6, enabling pre-loading of materials and improving loading efficiency. It also implements intelligent identification control, improving efficiency while further protecting the materials.

[0042] The mounting assembly 1 comprises a support base 11, a mounting frame 12, a mounting platform 13, and a connecting rod 14. The support base 11 and mounting frame 12 are arranged in two sets, symmetrically on both sides. The upper end surface of the support base 11 is fixedly connected to the lower end surface of each mounting frame 12, and the ends of the connecting rod 14 are fixedly connected to the inner upper ends of the mounting frames 12 on both sides. This arrangement allows the connecting rod 14 and the two mounting frames 12 to roughly form a portal frame in this embodiment. Two bearings 33 are fixedly mounted to the upper ends of the two mounting frames 12, respectively, and the drive shaft 32 is parallel to the connecting rod 14.

[0043] The mounting platform 13 is fixedly mounted on the right side wall of the right mounting frame 12 . The mounting frame 12 is connected to the sprocket assembly 31 . The auxiliary support assembly 4 and the detection and control assembly 5 are respectively arranged on the mounting frame 12 . The mounting platform 13 is connected to the drive assembly 2 .

[0044] The driving assembly 2 includes a reduction motor 21 and a pulley assembly 22. The reduction motor 21 is fixedly mounted on the upper end surface of the mounting platform 13. The output end of the reduction motor 21 is connected to the transmission shaft 32 through the pulley assembly 22. The pulley assembly 22 consists of two synchronous pulleys and a belt, both of which adopt existing mature technologies.

[0045] Each sprocket assembly 31 includes a chain 311 and two sprockets 312. The two sprockets 312 are spaced apart from each other along the height direction of the corresponding mounting frame 12. The upper sprocket 312 is fixedly connected to the transmission shaft 32, and the lower sprocket 312 is rotatably connected to the mounting frame 12. The upper sprocket 312 and the lower sprocket 312 are connected by the chain 311. That is, the chain 311 is sleeved on the two sprockets 312, and the chain 311 is slidably connected to the outer wall of the mounting frame 12.

[0046] Start the reduction motor 21, and the output end of the reduction motor 21 drives the transmission shaft 32 through the pulley assembly 22. The rotation of the transmission shaft 32 drives the sprocket 312 at the upper end to rotate. The sprocket 312 at the upper end cooperates with the sprocket 312 at the lower end through the chain 311. The operation of the chain 311 drives the fixed block 34 to rise and fall.

[0047] The inner wall of the installation and fixing component 1 is installed with an auxiliary support component 4 for auxiliary support. There are four groups of auxiliary support components 4, two groups of auxiliary support components 4 are arranged up and down on one side of the installation and fixing component 1, and the other two groups of auxiliary support components 4 are symmetrically arranged on the other side of the installation and fixing component 1.

[0048] Specifically, two groups of auxiliary support components 4 are arranged vertically on the inner side wall of the left mounting frame 12 , and the other two groups of auxiliary support components 4 are symmetrically arranged on the inner side wall of the right mounting frame 12 .

[0049] When the detection and control assembly 5 at the lower end detects that the material in the material assembly assembly 6 has reached a certain standard, it will start the reduction motor 21 to drive the pulley assembly 22, which in turn drives the transmission shaft 32, which in turn drives the sprocket assembly 31, which in turn drives the fixed block 34, thereby delivering the material assembly 6 to the auxiliary support assembly 4 located above. When the detection and control assembly 5 at the upper end detects that the material has reached the specified position, it will turn off the reduction motor 21. At this time, the auxiliary support assembly 4 below can load a new material assembly 6.

[0050] Specifically, the auxiliary support assembly 4 includes a mounting plate 41, a connecting shaft 42, and an auxiliary clamping block 43. The mounting plate 41 is fixedly connected to the mounting frame 12, one end of the connecting shaft 42 is fixedly connected to the outer wall of the mounting plate 41, and the auxiliary clamping block 43 is rotatably connected to the connecting shaft 42. The front end of the auxiliary clamping block 43 and the fixed clamping block 34 are located on the same side of the mounting and fixing assembly 1. When the auxiliary clamping block 43 is in an initial state, the auxiliary clamping block 43 is in a horizontal state. When the auxiliary clamping block 43 is subjected to an upward force, the front end of the auxiliary clamping block 43 rotates upward.

[0051] The auxiliary support assembly 4 further includes a limit block 44, which is fixedly mounted on the outer wall of the mounting plate 41. The limit block 44 is disposed on the front side of the connecting shaft 42 and is located below the front end of the auxiliary clamping block 43. The limit block 44 abuts against the auxiliary clamping block 43.

[0052] The connecting shaft 42 and the limit block 44 are fixedly installed on the mounting plate 41, and the auxiliary block 43 can rotate on the connecting shaft 42. When the fixed block 34 drives the material assembly component 6 to rise, the auxiliary block 43 is subjected to an upward force, and the front end of the auxiliary block 43 is lifted to avoid. After the avoidance is completed, the auxiliary block 43 naturally falls back, and the limit block 44 provides limited support for the auxiliary block 43. At this time, the fixed block 34 can place the material assembly component 6 into the auxiliary block 43 for operation.

[0053] When passing through the auxiliary support assembly 4, the auxiliary support assembly 4 can avoid it. After the avoidance is completed, the fixed block 34 descends and the material assembly assembly 6 can be placed on the auxiliary support assembly 4 located below it;

[0054] Specifically, the detection control component 5 includes a limit switch 51 and a detection component 52. There are two limit switches 51, which are arranged up and down and fixedly installed on the left wall of the left mounting frame 12; there are two groups of detection components 52, which are arranged up and down and fixedly installed on the right wall of the left mounting frame 12.

[0055] The material assembly component 6 includes a mounting shaft 61 and a material roll 62 . The mounting shaft 61 is engaged with the fixed blocks 34 on both sides, and the material roll 62 is rotatably mounted on the mounting shaft 61 .

[0056] When the detection component 52 at the lower end detects that the material roll 62 has been used to a certain extent, the motor will be started to lift the mounting shaft 61 through the fixed block 34 to lift the material roll 62 to above the auxiliary block 43 at the upper end; after the upper end detection component 52 detects the material roll 62, it will descend and clamp the material roll 62 into the auxiliary block 43 at the upper end; the fixed block 34 at the lower end can be equipped with a new material assembly component 6. When the fixed block 34 is manually controlled by the limit switch 51, the detection components 52 at both ends can limit the stroke of the fixed block 34. When the stroke is exceeded, the detection component 52 will control the reduction motor 21 to cut off the power to prevent damage to the equipment. The detection component 52 contains a contact sensor and a laser sensor. The contact sensor can detect whether the fixed block 34 is in contact. When in contact, the reduction motor 21 will be controlled to cut off the power. The laser sensor can detect the use of the material roll 62.

[0057] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
