Description

Technical Field

[0001] The invention relates to the technical field of belt conveyors, and in particular to a chemical barrel belt conveyor device for warehouse logistics. Background Art

[0002] Warehouse logistics is a key link in the modern logistics system, covering a series of processes such as storage, sorting, packaging, handling and distribution of goods. It aims to efficiently manage the entry and exit of goods and ensure the smooth operation of the supply chain. Chemical barrels in warehouse logistics are loaded with various chemicals, so special attention should be paid to safety and stability during handling and transportation. Therefore, a belt conveyor with stable transmission is used to avoid the risk of leakage caused by bumps and shaking of chemical barrels during transportation, thereby ensuring the safety of chemicals.

[0003] In the warehouse logistics system, when a new chemical product production line is introduced, if the position of the discharge port of the production line cannot be adapted to the existing belt conveyor, it is often necessary to adjust the length of the conveyor to achieve precise docking with the new production line, so as to smoothly receive and transport the newly produced chemical barrels; however, most of the existing belt conveyors are fixed in length and difficult to change flexibly according to actual needs. Even if some conveyors have a length adjustment function, the internal support structure cannot be adjusted synchronously, resulting in a lack of effective support for the adjusted length section. This is very likely to affect the stability and transportation safety of chemical barrels loaded with chemicals when transporting them, and it is difficult to meet the stringent requirements of chemical product warehousing logistics for the smooth and safe transportation of goods.

[0004] Therefore, it is necessary to provide a chemical barrel belt conveyor for warehouse logistics, aiming to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0018] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0019] See also Figures 1 to 10 As shown, the present invention provides an embodiment: A chemical barrel belt conveyor for warehouse logistics, comprising a bracket 1, a conveyor belt 2, an adjustment component 3 and an auxiliary component 4 are arranged inside the bracket 1, the adjustment component 3 comprises a support structure 31, an adjustment structure 32, a tensioning structure 33 and a guide structure 34, a sliding seat 35 is symmetrically slidably connected inside the bracket 1, and a baffle 5 is symmetrically fixedly connected to the top of the bracket 1; The supporting structure 31 comprises a support rod 1 311, a support rod 2 312, a mounting shaft 313, a support roller 316, a guide roller 317 and a push block 318. The support rod 1 311 and the support rod 2 312 are cross-distributed with the mounting shaft 313 as the center. The tops of the support rod 1 311 and the support rod 2 312 are both slidably connected with a movable seat 314, and the top of the movable seat 314 is rotatably connected with the support rod 3 315. The support roller 316 is rotatably connected to the top of the support rod 1 311, the top of the support rod 2 312 and the support rod 3 315 through a pin shaft, respectively, the guide roller 317 is rotatably connected to the bottom of the support rod 1 311 and the bottom of the support rod 2 312 through a pin shaft, and the push block 318 is rotatably connected to the bottom of the support rod 1 311 and the bottom of the support rod 2 312 through a pin shaft, and a transmission connection is formed between the conveyor belt 2 and the support roller 316 and the guide roller 317. The adjustment structure 32 includes a driving sleeve 321 rotatably connected to the bottom of the bracket 1, a bidirectional screw 324 is fixedly connected to the outer side of the driving sleeve 321, a push rod 323 is slidably connected to the inner wall of the bottom of the bracket 1, and the push rods 323 form a spiral pair transmission with the bidirectional screw 324 in a group of two, and the bottom of the push block 318 is symmetrically fixedly connected to the mounting frame 36, a support rod 322 is rotatably connected between the slide seat 35 and the mounting frame 36, and the push rod 323 is rotatably connected to the slide seat 35 through the support rod 322; The push rod 323 is slidably connected to the inner wall of the bottom of the bracket 1, and the driving sleeve 321 is slidably connected to the inside of the starting rod 325, and the top of the starting rod 325 is fixedly connected to a block 326, and one end of the starting rod 325 is fixedly connected to a handle 327; The tensioning structure 33 is symmetrically distributed on the outer side of the conveyor belt 2 to ensure that the conveyor belt 2 is always in a tensioned state; The guide structure 34 is located on the top of the conveyor belt 2, ensuring that the support roller 316 can only move in the horizontal direction.

[0020] In practical application, the embodiment of the present invention is as follows: Figure 3 , Figure 4 , Figure 5 and Fig.10 As shown, the handle 327 is rotated to drive the start rod 325 to move, so that the block 326 is engaged with the drive sleeve 321, and then the drive sleeve 321 is rotated, and the drive sleeve 321 drives the bidirectional screw rod 324 to rotate, and the push rod 323 that forms a spiral pair transmission with the bidirectional screw rod 324 slides on the inner wall of the bottom of the bracket 1, and pushes the slide seat 35 to slide in the bracket 1 through the support rod 322; like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, when the slide 35 moves, the mounting frame 36 moves accordingly to drive the push block 318. The push block 318 moves upward to push the bottom of the support rod 1 311 and the support rod 2 312, so that the support rod 1 311 and the support rod 2 312 rotate around the mounting shaft 313 to achieve the opening of the top and the bottom. In this process, the distance between the support roller 316 and the guide roller 317 changes. Under the restriction of the guide structure 34, the support roller 316 moves horizontally to open the conveyor belt 2. The tensioning structure 33 ensures that the conveyor belt 2 is always tensioned. At the same time, the distribution of the support roller 316 and the guide roller 317 in the support structure 31 changes to strengthen the support for the conveyor belt 2, realize the adjustment of the conveying length, and ensure the safe transportation of fully loaded chemical barrels.

[0021] like Figure 2 , Figure 4 and Fig. 9 As shown, the tensioning structure 33 includes a tensioning roller 331 and a mounting seat 332. The mounting seat 332 is fixedly connected to the outer side of the mounting shaft 313. The interior of the mounting seat 332 is slidably connected with a movable sleeve 333 and a mounting block 335. A spring 336 is fixedly connected between the movable sleeve 333 and the mounting block 335. The interior of the mounting seat 332 is rotatably connected with a one-way screw rod 334. A spiral pair transmission is formed between the movable sleeve 333 and the one-way screw rod 334. The tensioning roller 331 is rotatably connected to the mounting block 335 via a pin shaft.

[0022] When the embodiment of the present invention is actually applied, as the position of the mounting shaft 313 in the support structure 31 changes, the mounting seat 332 fixed on its outer side is driven to move. When the conveyor belt 2 becomes loose or the tension changes due to reasons such as adjustment of the conveying length, the one-way screw 334 can be rotated. Since the movable sleeve 333 and the one-way screw 334 form a spiral pair transmission, the movable sleeve 333 will slide along the axial direction of the screw in the mounting seat 332. During the sliding process, the movable sleeve 333 pushes the mounting block 335, so that the mounting block 335 drives the tensioning roller 331 away from the conveyor belt 2. The spring 336 plays a role of buffering and adaptive adjustment. When the conveyor belt 2 changes in tightness due to various factors, the spring 336 can automatically expand and contract, drive the tensioning roller 331 to adjust its position, and always maintain a moderate tension on the conveyor belt 2, so as to ensure the stable operation of the conveyor belt 2 and avoid slipping or loosening, thereby ensuring the safe and reliable transportation process of the fully loaded chemical barrels.

[0023] like Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the guide structure 34 includes a connecting plate 341 and a guide seat 342, the guide seat 342 is fixedly connected to the inner wall of the bracket 1, the support roller 316 is slidably connected to the guide seat 342 through an anti-bias structure 37, a slide plate 345 is symmetrically slidably connected between the mounting frames 36, the connecting plate 341 is fixedly connected to the slide plate 345, a guide block 1 343 and a guide block 2 344 are symmetrically fixedly connected between the connecting plates 341, and the push block 318 is slidably connected to the slide plate 345.

[0024] When the embodiment of the present invention is actually used, the guide seat 342 fixed on the inner wall of the bracket 1 is slidably connected to the support roller 316 through the anti-bias structure 37, strictly limiting the moving direction of the support roller 316 so that it can only move in the horizontal direction. When the push block 318 moves driven by the mounting frame 36, the push block 318 slides in the slide plate 345, thereby pushing the slide plate 345 to slide symmetrically between the mounting frames 36, and the connecting plate 341 fixedly connected to the slide plate 345 moves synchronously. The guide block 1 343 and the guide block 2 344 symmetrically fixed between the connecting plates 341 assist the entire structure to move smoothly in the horizontal direction, prevent offset or jamming when adjusting the support structure 31, and work together with the tensioning structure 33 to jointly ensure the stability and safety of the conveyor belt 2 during the adjustment of the conveying length, laying a solid foundation for the safe transportation of chemical barrels.

[0025] like Figure 4 , Figure 5 and Figure 8 As shown, the anti-bias structure 37 includes a connecting seat 371 and a connecting block 372. The connecting seat 371 is rotatably connected to the support rod 315 through a pin shaft and the connecting seat 371. The connecting block 372 is rotatably connected to the support rod 1 311 and the support rod 2 312 through a pin shaft respectively. A telescopic rod 373 is fixedly connected between the connecting block 372 and the connecting seat 371.

[0026] In actual application of the embodiment of the present invention, when support rod 1 311 and support rod 2 312 rotate around the installation axis 313, the connecting block 372 moves accordingly, and the telescopic rod 373 adaptively retracts and contracts, guiding support rod 3 315 and support roller 316 to move smoothly through the connecting seat 371 to prevent them from being skewed during the adjustment process.

[0027] like Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, the auxiliary component 4 includes a fixed seat 41 symmetrically fixedly connected to the outside of the bracket 1, and the outside of the fixed seat 41 is symmetrically fixedly connected to a limit seat 42, and the inside of the limit seat 42 is rotatably connected to a variable pitch screw 43, and the pitch of the variable pitch screw 43 at one end away from the fixed seat 41 is set to twice that of the other end. The inside of the limit seat 42 is also slidably connected to two sliders 44, and a spiral pair transmission is formed between the sliders 44 and the variable pitch screw 43. The sliders 44 are fixedly connected to the mounting shaft 313, and the inside of the fixed seat 41 is rotatably connected to a connecting shaft 46, and a transmission shaft 45 is rotatably connected between the two fixed seats 41, and a worm 47 is fixedly connected to the outside of the transmission shaft 45, and a worm wheel 48 is fixedly connected to the outside of the connecting shaft 46, and the worm 47 and the worm wheel 48 are meshed with each other.

[0028] When the embodiment of the present invention is used in practice, the transmission shaft 45 is rotated, and the worm 47 fixedly connected to its outer side rotates accordingly, and the worm wheel 48 meshing with the worm 47 drives the connecting shaft 46 to rotate, thereby causing the variable pitch screw 43 to rotate in the limit seat 42. Since the pitch of one end of the variable pitch screw 43 is twice that of the other end, the two sliders 44 forming a spiral pair transmission with the variable pitch screw 43 will slide in the limit seat 42 at different rates according to the pitch difference. The slider 44 is fixedly connected to the mounting shaft 313, so that the mounting shaft 313 can accurately adjust the spacing according to the rotation of the variable pitch screw 43 and the displacement of the slider 44, and ensure the synchronous change of the distance between each mounting shaft 313, so that the distribution of the support structure 31 in the conveyor belt 2 is more uniform and reasonable, and the support effect on the conveyor belt 2 is further enhanced, thereby improving the accuracy and stability of the conveying length adjustment, and comprehensively guaranteeing the safe and efficient transportation of fully loaded chemical barrels.
