Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, in particular to a transport belt lifting mechanism. Background Art

[0002] In the aluminum profile processing industry, oxidation is an important surface treatment process.

The oxidation production line typically includes multiple steps such as degreasing, alkaline etching, neutralization, anodizing, coloring (or electrolytic coloring), and sealing.

[0003] Traditional material handling methods primarily involve manual handling and the use of simple lifting equipment. However, with the continuous advancement of industrial automation and the growing demand for production efficiency, these methods have gradually revealed some problems.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figures 1 to 7As shown, the utility model proposes a transport belt lifting mechanism, including a connecting rod 3, one end of the connecting rod 3 is installed with a first lifting mechanism 1, the other end of the connecting rod 3 is installed with a second lifting mechanism 2, the first lifting mechanism 1 includes a push-pull mechanism 12, one end of the push-pull mechanism 12 is hinged with a transmission arm 13, one end of the transmission arm 13 is clamped with a first rotating shaft 15, the first rotating shaft 15 is clamped with the connecting rod 3, the outer shell of the first rotating shaft 15 is provided with a first telescopic force arm 11, the first telescopic force arm 11 is clamped with the first rotating shaft 15 One end of the first telescopic arm 11 is hinged to the first support rod 14, and the second lifting mechanism 2 includes a second rotating shaft 23, which is clamped to the connecting rod 3. The second rotating shaft 23 is clamped to the second telescopic arm 21, and one end of the second telescopic arm 21 is hinged to the second support rod 22. The first support rod 14 and the first support rod 14 have a telescopic function. The specifications and structure of the second support rod 22 and the second telescopic arm 21 are the same as the specifications and structure of the first support rod 14 and the first telescopic arm 11. The first lifting mechanism 1 and the second lifting mechanism 2 can be connected to different conveyor belts respectively. Specifically, one end of the first support rod 14 and the second support rod 22 is hinged to the side wall of the conveyor belt. The push-pull mechanism 12 serves as the power source for the first lifting mechanism 1 and the second lifting mechanism 2. When the push-pull mechanism 12 moves, it pushes or pulls the transmission arm 13 hinged thereto, thereby driving the transmission arm 13 to rotate. When the transmission arm 13 rotates, it drives the first rotating shaft 15 to rotate. Further, the first rotating shaft 15 drives the first telescopic force arm 11 to rotate. When the first telescopic force arm 11 rotates, it drives the first support rod 14 to move upward. When the first support rod 14 moves upward, it drives the conveying belt connected to it to move upward. When the first rotating shaft 15 rotates, the rotation force is transmitted to the second rotating shaft 23 through the connecting rod 3. When the second rotating shaft 23 rotates, it drives the second telescopic force arm 21 to rotate. Further, the second telescopic force arm 21 drives one end of the second support rod 22 to move upward, thereby driving the conveying belt connected to the second support rod 22 to lift. By adjusting the length of the first telescopic force arm 11 and the first support rod 14 or the second telescopic force arm 21 and the second support rod 22, the height adjustment of different conveying belts can be achieved, thereby realizing that one conveying belt lifting mechanism can lift multiple conveyor belts to different heights at the same time, which is highly practical.

[0032] Furthermore, as a preferred embodiment of the present invention but not a limitation, both ends of the first rotating shaft 15 are equipped with a first matching portion 17, and both ends of the second rotating shaft 23 are equipped with a second matching portion 26 with the same specifications and structure as the first matching portion 17. The connecting rod 3 includes a sleeve 31, and the interior of the sleeve 31 is sleeved with a first sleeve rod 32 and a second sleeve rod 33. The first sleeve rod 32 and the second sleeve rod 33 are both slidably connected to the inner cavity of the sleeve 31, and one end of the first sleeve rod 32 and the second sleeve rod 33 are fixedly connected with a connecting portion 36. The first matching portion 17 and the second matching portion 26 are both engaged with the connecting portion 36. The inner cavity of the sleeve 31 is provided with at least one convex strip 35, and the first sleeve rod 32 and the second sleeve rod 33 are both provided with a groove 34 engaged with the convex strip 35. Sleeve 31, as the main component of connecting rod 3, provides a closed and stable environment to accommodate internal components. The first sleeve rod 32 and the second sleeve rod 33 are respectively connected to the first rotating shaft 15 and the second rotating shaft 23 and can slide within sleeve 31, which allows the relative position of the two lifting mechanisms to change, thereby supporting adjustments of different widths. Connecting portion 36 is located at one end of the first sleeve rod 32 and the second sleeve rod 33 and is used to fix the two sleeve rods to the first mating portion 17 and the second mating portion 26. The first mating portion 17 and the second mating portion 26 are installed at both ends of their respective rotating shafts. By engaging with the connecting portion 36, a stable connection between the rotating shaft and the sleeve rod is ensured. The combined use of the protrusion 35 and the groove 34 prevents unnecessary rotation and also enhances the rigidity and guidance of the entire connecting rod 3.

[0033] Furthermore, as a preferred embodiment of the present invention but not limiting, the push-pull mechanism 12 is a combination of one or more of a hydraulic cylinder, a pneumatic cylinder, and an electric push rod.

[0034] Furthermore, as a preferred embodiment of the present invention, but not limiting, the first mating portion 17 and the second mating portion 26 are slots, and the connecting portion 36 is a clamping block. Designing the connecting portion 36 as a clamping block and embedding it within the slot provides a more stable mechanical connection. The combined connection of the clamping block and the slot facilitates installation and removal, simplifying assembly and maintenance.

[0035] Optionally, in some embodiments, the first matching portion 17 and the second matching portion 26 are blocks, and the connecting portion 36 is a slot.

[0036] Furthermore, as a preferred embodiment of the present invention but not a limitation thereof, a first limiting pin 16 is sleeved within the side wall of the first mating portion 17, the first limiting pin 16 being threadedly connected to the first mating portion 17, and a second limiting pin 25 is sleeved within the side wall of the second mating portion 26, the second limiting pin 25 being threadedly connected to the second mating portion 26. By twisting the first limiting pin 16, one end of the first limiting pin 16 presses against the connecting portion 36 engaged in the first mating portion 17, thereby preventing the connecting portion 36 from easily moving out of the first mating portion 17. By twisting the second limiting pin 25, one end of the second limiting pin 25 presses against the connecting portion 36 engaged in the second mating portion 26, thereby preventing the connecting portion 36 from easily moving out of the second mating portion 26. This improves the stability of the connection between the connecting rod 3 and the first lifting mechanism 1 and the second lifting mechanism 2.

[0037] Furthermore, as a preferred embodiment of the present invention but not a limitation, the first telescopic arm 11 includes an upper arm 111 and a lower arm 115, the lower arm 115 is provided with a through slot 114, one end of the upper arm 111 is fixedly connected to a screw rod 117, one end of the screw rod 117 is arranged in the lower arm 115, the screw rod 117 is slidingly connected to the lower arm 115, a nut 113 is provided in the through slot 114, the nut 113 is sleeved on the outside of the screw rod 117, and the nut 113 is threadedly connected to the screw rod 117. When the length of the telescopic arm needs to be adjusted, the nut 113 is screwed. Since the nut 113 is limited in the through groove 114, the screw rod 117 will move as the nut 113 is screwed while the position of the nut 113 remains unchanged. As the screw rod 117 moves, the screw rod 117 will push or pull the upper arm 111, thereby extending or shortening the upper arm 111 relative to the lower arm 115.

[0038] Furthermore, as a preferred embodiment of the present invention but not limiting, at least one positioning slot 116 is defined at one end of the lower lever arm 115, and at least one positioning block 112 that matches the positioning slot 116 is fixedly connected to one end of the upper lever arm 111. When the upper lever arm 111 moves, the positioning block 112 slides within the positioning slot 116, thereby providing an additional guiding function, ensuring that the upper lever arm 111 moves smoothly along a predetermined path, improving the stability and reliability of the telescopic action, and providing additional mechanical support for the connection between the lower lever arm 115 and the upper lever arm 111.

[0039] Furthermore, as a preferred embodiment of the present invention but not a limitation, the second support rod 22 includes a rod body 221, a first hinge rod 222 is sleeved in one end of the rod body 221, a second hinge rod 224 is sleeved in one end of the rod body 221, and the first hinge rod 222 and the second hinge rod 224 are both threadedly connected to the rod body 221. A slot 223 is provided on the side wall of the rod body 221. When the length of the second support rod 22 needs to be adjusted, the extension length of the first hinge rod 222 and the second hinge rod 224 in the rod body 221 can be changed by rotating the rod body 221, thereby achieving the length adjustment of the support rod. The separate design of the rod body 221 and the first hinge rod 222 and the second hinge rod 224 means that even if one of the components is damaged, it can be replaced separately without replacing the entire support rod, thereby reducing maintenance costs.

[0040] Example 1:

[0041] A transport belt lifting mechanism includes a connecting rod 3, one end of which is mounted a first lifting mechanism 1, and the other end of which is mounted a second lifting mechanism 2. The first lifting mechanism 1 includes a push-pull mechanism 12, which is a hydraulic cylinder. One end of the push-pull mechanism 12 is hinged with a transmission arm 13, and one end of the transmission arm 13 is clamped with a first rotating shaft 15. The first rotating shaft 15 is clamped with the connecting rod 3, and the outer shell of the first rotating shaft 15 is provided with a first telescopic force arm 11. The first telescopic force arm 11 is connected to the first rotating shaft 15. The first telescopic arm 11 is connected at one end to a first support rod 14, and the second lifting mechanism 2 includes a second rotating shaft 23, which is connected to the connecting rod 3. The second rotating shaft 23 is connected to the second telescopic arm 21, and one end of the second telescopic arm 21 is hinged to the second support rod 22. The first support rod 14 and the first support rod 14 have a telescopic function. The specifications and structure of the second support rod 22 and the second telescopic arm 21 are the same as those of the first support rod 14 and the first telescopic arm 11. The first lifting mechanism 1 and the second lifting mechanism 2 can be connected to different conveyor belts respectively. Specifically, one end of the first support rod 14 and the second support rod 22 is hinged to the side wall of the conveyor belt. The push-pull mechanism 12 serves as the power source for the first lifting mechanism 1 and the second lifting mechanism 2. When the push-pull mechanism 12 moves, it pushes or pulls the transmission arm 13 hinged thereto, thereby driving the transmission arm 13 to rotate. When the transmission arm 13 rotates, it drives the first rotating shaft 15 to rotate. Further, the first rotating shaft 15 drives the first telescopic force arm 11 to rotate. When the first telescopic force arm 11 rotates, it drives the first support rod 14 to move upward. When the first support rod 14 moves upward, it drives the conveying belt connected to it to move upward. When the first rotating shaft 15 rotates, the rotation force is transmitted to the second rotating shaft 23 through the connecting rod 3. When the second rotating shaft 23 rotates, it drives the second telescopic force arm 21 to rotate. Further, the second telescopic force arm 21 drives one end of the second support rod 22 to move upward, thereby driving the conveying belt connected to the second support rod 22 to lift. By adjusting the length of the first telescopic force arm 11 and the first support rod 14 or the second telescopic force arm 21 and the second support rod 22, the height adjustment of different conveying belts can be achieved, thereby realizing that one conveying belt lifting mechanism can lift multiple conveyor belts to different heights at the same time, which is highly practical.

[0042] Both ends of the first rotating shaft 15 are equipped with a first matching portion 17, and both ends of the second rotating shaft 23 are equipped with a second matching portion 26 with the same specifications and structure as the first matching portion 17. The connecting rod 3 includes a sleeve 31, and the interior of the sleeve 31 is sleeved with a first sleeve rod 32 and a second sleeve rod 33. The first sleeve rod 32 and the second sleeve rod 33 are both slidably connected to the inner cavity of the sleeve 31, and one end of the first sleeve rod 32 and the second sleeve rod 33 are fixedly connected with a connecting portion 36. The first matching portion 17 and the second matching portion 26 are both engaged with the connecting portion 36. The inner cavity of the sleeve 31 is provided with at least one convex strip 35, and the first sleeve rod 32 and the second sleeve rod 33 are both provided with a groove 34 engaged with the convex strip 35. The sleeve 31, as the main component of the connecting rod 3, provides a closed and stable environment to house the internal components. The first and second sleeve rods 32 and 33 are connected to the first and second rotating shafts 15 and 23, respectively, and can slide within the sleeve 31. This allows the relative position of the two lifting mechanisms to be adjusted, thereby supporting different width adjustments. Connecting portions 36 are located at one end of the first and second sleeve rods 32 and 33 and are used to secure the two sleeve rods to the first and second mating portions 17 and 26. The first and second mating portions 17 and 26 are mounted on either end of their respective rotating shafts. By engaging with the connecting portions 36, they ensure a secure connection between the rotating shaft and the sleeve rods. The combined use of the ridges 35 and grooves 34 prevents unwanted rotation while also enhancing the rigidity and guidance of the entire connecting rod 3. The first and second mating portions 17 and 26 are grooves, and the connecting portion 36 is a block. Designing the connecting portion 36 as a block and embedding it into the grooves provides a more stable mechanical connection. The combined connection mode of the clamping block and the trough body is easy to install and disassemble, thereby simplifying the assembly and maintenance process.

[0043] A first limiting pin 16 is sleeved within the side wall of the first mating portion 17 and is threadedly connected to the first mating portion 17. A second limiting pin 25 is sleeved within the side wall of the second mating portion 26 and is threadedly connected to the second mating portion 26. By twisting the first limiting pin 16, one end of the first limiting pin 16 presses against the connecting portion 36 engaged in the first mating portion 17, thereby preventing the connecting portion 36 from easily moving out of the first mating portion 17. By twisting the second limiting pin 25, one end of the second limiting pin 25 presses against the connecting portion 36 engaged in the second mating portion 26, thereby preventing the connecting portion 36 from easily moving out of the second mating portion 26. This improves the stability of the connection between the connecting rod 3 and the first lifting mechanism 1 and the second lifting mechanism 2.

[0044] The first telescopic arm 11 includes an upper arm 111 and a lower arm 115. The lower arm 115 is provided with a through slot 114. One end of the upper arm 111 is fixedly connected to a screw rod 117. One end of the screw rod 117 is disposed in the lower arm 115. The screw rod 117 is slidably connected to the lower arm 115. A nut 113 is disposed in the through slot 114. The nut 113 is sleeved on the screw rod 117 and is threadedly connected to the screw rod 117. When the length of the telescopic arm needs to be adjusted, the nut 113 is turned. Since the nut 113 is limited in the through slot 114, the screw rod 117 moves as the nut 113 is turned while the nut 113 remains in position. As the screw rod 117 moves, the screw rod 117 pushes or pulls the upper arm 111, thereby extending or shortening the upper arm 111 relative to the lower arm 115.

[0045] At least one positioning slot 116 is defined at one end of the lower arm 115, and at least one positioning block 112 is fixedly connected to one end of the upper arm 111, matching the positioning slot 116. When the upper arm 111 moves, the positioning block 112 slides within the positioning slot 116, thereby providing additional guidance, ensuring that the upper arm 111 moves smoothly along a predetermined path, improving the stability and reliability of the telescopic movement, and providing additional mechanical support for the connection between the lower arm 115 and the upper arm 111.

[0046] The second support rod 22 includes a rod body 221, one end of which is provided with a first hinge rod 222, and one end of which is provided with a second hinge rod 224. The first hinge rod 222 and the second hinge rod 224 are both threadedly connected to the rod body 221. A slot 223 is provided on the side wall of the rod body 221. When the length of the second support rod 22 needs to be adjusted, the extension length of the first hinge rod 222 and the second hinge rod 224 in the rod body 221 can be changed by rotating the rod body 221, thereby adjusting the length of the support rod. The separate design of the rod body 221 and the first hinge rod 222 and the second hinge rod 224 allows for individual replacements even if one of the components is damaged, without the need to replace the entire support rod, thereby reducing maintenance costs.

[0047] The implementation method of the second embodiment is as follows:

[0048] The difference between Example 2 and Example 1 is that the first lifting mechanism 1 can be simultaneously connected to two second lifting mechanisms 2 through the connecting rod 3. Specifically, the two connecting rods 3 are connected to both sides of the first lifting mechanism 1 through the first matching portion 17 and the connecting portion 36, and then the second lifting mechanisms 2 are connected at one end of the two connecting rods 3 through the second matching portion 26 and the connecting portion 36. In this way, one first lifting mechanism 1 drives the two second lifting mechanisms 2 to work synchronously, providing greater flexibility and higher work efficiency for practical applications.

[0049] Through the above-mentioned connection method, a new second lifting mechanism 2 can be connected to one side of the second lifting mechanism 2, thereby further improving work efficiency.

[0050] Specifically, the working principle of the present invention is as follows:

[0051] When in use, the first lifting mechanism 1 and the second lifting mechanism 2 can be connected to different transport belts respectively. The push-pull mechanism 12 is activated, generating linear push-pull, and further push-pull force acts on the transmission arm 13, causing it to rotate around the hinge point. The rotation of the transmission arm 13 drives the first rotating shaft 15 to rotate, and the rotation of the first rotating shaft 15 is transmitted to the first telescopic force arm 11 through a snap-on connection, causing the first telescopic force arm 11 to rotate accordingly. The rotation of the first telescopic force arm 11 further drives the first support rod 14 to move upward, thereby lifting the transport belt connected to it. At the same time, the rotational force is transmitted to the second rotating shaft 23 through the sleeve 31, the first set of rods 32 and the second set of rods 33 in the connecting rod 3. The rotation of the second rotating shaft 23 also drives the second telescopic force arm 21 to rotate, and then drives the second support rod 22 to move upward, lifting another transport belt.

[0052] If the height of the conveyor belt needs to be adjusted, this can be achieved by adjusting the length of the first telescopic arm 11 and the second telescopic arm 21. Specifically, by turning the nut 113, the screw rod 117 moves, thereby changing the position of the upper arm 111 relative to the lower arm 115. The support rod can change the extension length of the first hinge rod 222 and the second hinge rod 224 within the rod body 221 by rotating the rod body 221, thereby achieving length adjustment.

[0053] The transport belt lifting mechanism can effectively control two different transport belts at the same time, and can adjust their respective heights according to actual needs, thereby improving the flexibility and practicality of operation.

[0054] In summary, the utility model solves the problem that the traditional conveyor belt lifting mechanism cannot lift multiple conveyor belts to different heights at the same time.

[0055] It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms, which are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, the "first" information may also be referred to as the "second" information, and similarly, the "second" information may also be referred to as the "first" information. In addition, the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside", etc., which indicate orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as limiting the present invention.

[0056] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
