Description

Technical Field

[0001] This utility model relates to the field of conveying equipment technology, specifically a circulating transfer device. Background Technology

[0002] Timber refers to wood or wood materials used for various purposes such as construction, furniture making, carving, and handicrafts. During the processing of timber, transfer equipment is needed to transport the timber to the corresponding processing equipment.

[0003] Utility model patent CN213140322U discloses a wood conveying device for automated production and processing of wooden doors. This device includes a base, a support column fixedly connected to the upper surface of the base, a transmission box fixedly connected to the upper surface of the support column, a slot on the upper surface of the transmission box, a conveyor belt inside the slot, a transmission shaft rotatably connected to one side of the inner wall of the conveyor belt, a drive shaft drivingly connected to the middle of one side of the transmission shaft, a drive plate drivingly connected to one side of the drive shaft, a cavity in the middle of the outer surface of the drive plate, and a belt drivingly connected inside the cavity. The upper surface of the transmission box has a slot, inside which a conveyor belt is installed. A conveyor shaft is rotatably connected to one side of the inner wall of the conveyor belt. A drive shaft is driven to the middle of one side of the conveyor shaft. This effectively protects the conveyor belt as it passes through the transmission box and provides the necessary power to the conveyor shaft through the drive shaft, ensuring the operation of the conveyor belt. At the same time, it prevents sawdust from entering the conveyor belt and causing the conveyor shaft to jam. A cavity is opened in the middle of the outer surface of the transmission plate. A belt is driven to the inside of the cavity. A rotating column is driven to the bottom of one side of the belt, which effectively increases the power of the drive shaft and speeds up the transmission of wood.

[0004] Although the wood conveying device for automated wooden door production facilitates wood transport, it suffers from several problems in practical use: The device uses a conveyor belt to transfer wood, but the wood is prone to shifting during transport on the belt. This can lead to difficulties in conveying the wood to the processing equipment or causing it to detach from the conveyor belt, thus affecting subsequent wood processing. Therefore, we propose a circulating conveying device. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] This embodiment provides a technical solution:

[0034] Please see Figures 1-6 As shown, a circulating transfer device includes a base 1. Two strip grooves 10 are opened on both sides of the top of the base 1. A conveying part 2 is installed on the top of the base 1. The conveying part 2 includes two symmetrical side plates 20. Two idlers 21 are rotatably installed at both ends between the two side plates 20. A conveyor belt 22 is sleeved on the outside between the two idlers 21. A first motor 23 for driving the idlers 21 to rotate is installed on the rear outer wall of the left side plate 20.

[0035] The base 1 is provided with a limiting part 3, which includes two parallel and rotatably mounted double-ended lead screws 37 below the base 1. Both ends of the two double-ended lead screws 37 are provided with threaded grooves, and the threads of the two threaded grooves are rotated in opposite directions. This design facilitates the synchronous relative movement of the connecting blocks 32 on both sides of the double-ended lead screws 37. The right ends of the two double-ended lead screws 37 are coaxially keyed to pulleys 38, and a belt 380 is sleeved between the two pulleys 38. A second motor 39 is installed below the base 1 to drive the rotation of the rear double-ended lead screw 37.

[0036] Each double-ended lead screw 37 has a connecting block 32 threadedly connected to its threaded grooves at both ends. The top of the connecting block 32 passes through the strip groove 10 and is slidably connected to the strip groove 10. A bracket 31 is fixed to the top of each connecting block 32. The brackets 31 on the same double-ended lead screw 37 are symmetrically arranged. A fixing strip 30 is fixed between the tops of the two adjacent brackets 31 on the left and the tops of the two adjacent brackets 31 on the right. A detachable connecting seat 33 is provided on the side of the two fixing strips 30 that is close to each other. A horizontal plate 34 is fixed on the side of the two connecting seats 33 that is close to each other. Multiple detachable ear plates 35 are provided on the side of the two horizontal plates 34 that are close to each other. Guide wheels 36 for preventing wood deviation are rotatably installed on both the upper and lower surfaces of the ear plate 35 away from the horizontal plate 34 on the same side. The guide wheels 36 are located above the conveyor belt 22. A connecting shaft 360 is coaxially fixed between the upper and lower guide wheels 36. The connecting shaft 360 passes through the ear plate 35 and is rotatably connected to the ear plate 35.

[0037] Furthermore, multiple slots 340 are provided on the side of each of the two horizontal plates 34 that are close to each other. Multiple connecting bolts 341 are threaded to the top of the two horizontal plates 34. The bottom thread of the connecting bolts 341 passes through the top of the horizontal plate 34 and is inserted into the corresponding slot 340. Each ear plate 35 is fixed with a plug block 350 that engages with the slot 340. The connecting bolts 341 pass through the corresponding plug block 350. This design not only enhances the reliability and stability of the connection between the horizontal plates 34 and the ear plates 35, but also facilitates the disassembly and assembly of the ear plates 35, thereby facilitating subsequent replacement of the guide wheels 36.

[0038] Furthermore, each side wall of the connecting seat 33 near the fixing strip 30 is provided with a fixing groove 330, which is inserted into the fixing strip 30. Both ends of the fixing strip 30 are threaded with limit bolts 300, and both ends of the connecting seat 33 are pressed together by the limit bolts 300. The two limit bolts 300 can press together both ends of the connecting seat 33, ensuring a tight connection between the connecting seat 33 and the fixing strip 30, preventing loosening, and also providing the advantage of easy assembly and disassembly.

[0039] In this embodiment, the bracket 31 and the connecting block 32 are fixedly connected by bolts, and the overall shape of the bracket 31 is a right-angled triangle. The triangular design increases the stability of the bracket 31 and enables it to withstand greater loads. The bolt fixing method is not only stable and reliable, but also has the advantage of being easy to assemble and disassemble.

[0040] In this embodiment, the guide wheel 36 and the connecting shaft 360 are integrally formed, and the diameter of the guide wheel 36 is larger than the diameter of the connecting shaft 360. The integrally formed guide wheel 36 and connecting shaft 360 have better connection strength, ensuring the connection stability between the guide wheel 36 and the connecting shaft 360, thereby ensuring the stable positioning of the wood by the guide wheel 36.

[0041] In this embodiment, two fixing plates 12 are fixed on the left and right sides of the bottom of the base 1, respectively. The double-ended lead screw 37 passes through the two fixing plates 12, and the double-ended lead screw 37 is rotatably connected to the fixing plates 12 through bearings. The fixing plates 12 provide stable support and support for the rotation of the double-ended lead screw 37, ensuring the stable use of the double-ended lead screw 37.

[0042] In this embodiment, a guide rod 11 is fixedly connected inside the strip groove 10. The guide rod 11 passes through the connecting block 32 and is slidably connected to the connecting block 32. The guide rod 11 guides the horizontal movement of the connecting block 32, thereby ensuring the stability and smoothness of the horizontal movement of the bracket 31.

[0043] In this embodiment, both the fixing groove 330 and the fixing strip 30 have trapezoidal cross-sectional shapes, and the length of the fixing groove 330 is less than the length of the fixing strip 30. This design facilitates a stable fit between the fixing groove 330 and the fixing strip 30, increasing the stability of the connection.

[0044] It should be added that the insert block 350 and the ear plate 35 in this embodiment are integrally formed structures. The integrally formed insert block 350 and ear plate 35 have better connection strength, ensuring the reliable connection between the insert block 350 and ear plate 35, making it less likely for the insert block 350 and ear plate 35 to break, thereby ensuring the stable use of multiple guide wheels 36.

[0045] It is worth noting that the first motor 23 and the second motor 39 involved in this embodiment are existing conventional technologies, and will not be described in detail here.

[0046] Before use, the user first turns on the power to the second motor 39. The second motor 39 starts working, and the output shaft of the second motor 39 rotates, driving the double-ended lead screw 37 on the rear side to rotate. Through the transmission of the pulley 38 and belt 380, the double-ended lead screw 37 on the front side also starts to rotate. As the two double-ended lead screws 37 rotate, the connecting blocks 32 on both sides of the same double-ended lead screw 37 move synchronously relative to each other. The two connecting blocks 32 simultaneously drive the brackets 31 on both sides to move synchronously relative to each other. The brackets 31 drive the fixing strip 30 to move. The fixing strip 30 drives the connecting seat 33 and the horizontal plate 34 to move horizontally. The horizontal plate 34 simultaneously drives multiple ear plates 35 to move. The ear plates 35 drive multiple guide wheels 36 to move horizontally. When the guide wheels 36 on both sides move to the appropriate position, the user turns off the power to the second motor 39.

[0047] Next, the user first turns on the power to the first motor 23. The first motor 23 starts to work. The output shaft of the first motor 23 rotates, which drives the rear idler roller 21 to rotate. The idler roller 21 drives the conveyor belt 22 to move. The conveyor belt 22 then drives the wood to move horizontally. The wood moves between multiple guide wheels 36 on both sides. As the conveyor belt 22 rotates, the wood can be transported to the subsequent processing equipment.
