Description

Technical Field

[0001] The invention relates to the technical field of assembly lines, and more specifically, to an assembly line with adjustable length. Background Art

[0002] The assembly line, also known as the assembly line, is an industrial production method in which each production unit focuses on handling only a certain segment of the work to improve work efficiency and output. It generally consists of traction parts, load-bearing components, driving devices, tensioning devices, redirecting devices and supporting parts.

[0003] For example, Chinese patent 201821244122.5 discloses an assembly line structure, which includes: a processing table, two mutually parallel linear guides and two parallel assembly line guides; the two linear guides and two assembly line guides are both arranged on the upper surface of the processing table, and the two assembly line guides are both slidably connected to the two linear guides, and at least one can slide along the two linear guides; a screw rod for changing the distance between the two assembly line guides is arranged between the two assembly line guides. In specific practice, the inventors found the following defects: the length of the assembly line is fixed during use, and the required assembly line length will change due to equipment addition, logistics planning, etc. during the production process. At this time, only a new length of the assembly line can be replaced, which has great limitations. Summary of the invention

[0004] The technical problem to be solved by the embodiments of the present invention is that the length of the existing assembly line is fixed during use. When equipment is added or logistics is planned during the production process, the required length of the assembly line will change. At this time, the only option is to replace the assembly line with a new length, which has great limitations.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:

The lower end of the T-shaped support rod is provided with a second limit assembly, which can quickly and accurately adjust the length of the assembly line. The adjusted assembly line support is more stable, more applicable, and more convenient to use.

[0009] As an improvement of the present invention, the conveying assembly includes a bridge rod, a conveying roller, a conveyor belt and a rotating shaft. The bridge rod is symmetrically arranged front and back. The two adjacent bridge rods on the same side are rotatably connected by a rotating shaft. Conveying rollers are provided between the two corresponding rotating shafts in the longitudinal direction. The conveying rollers on the left and right sides are connected by conveyor belt transmission. The upper ends of the fixed brackets are fixedly connected to the corresponding bridge rods on the same side by angle locks, and the two rotating shafts at the center are respectively located in the corresponding strip openings in the middle of the sliding bracket.

[0010] As an improvement of the present invention, the outer side surface of the conveying roller is symmetrically provided with annular grooves front and back, and the inner side surface of the conveyor belt is symmetrically provided with convex strips matching the annular grooves to limit the conveyor belt.

[0011] As an improved method of the present invention, it also includes fixed blocks, which are respectively arranged on the bottom surfaces of the bridge rods at the left and right ends. A limiting roller is rotatably connected between the two corresponding front and rear fixed blocks, which can limit the bottom end of the conveyor belt.

[0012] As an improvement of the present invention, the limiting assembly includes a limiting bolt, a gear and a step groove. The step groove is symmetrically arranged at the upper end of the outer surface of the T-shaped support rod. The inside of the step groove is movably inserted with the limiting bolt. The ends of the limiting bolts are respectively threadedly connected to the screw holes set at the outer ends of the corresponding rotating shafts on the same side. The outer ends of the limiting bolts are rotatably connected with gears, and the inner walls of the step groove are evenly provided with tooth grooves matching the gears, so that the adjusted assembly line support is more stable.

[0013] As an improved embodiment of the present invention, the second limiting assembly includes a sliding frame plate, a stud, a limiting plate and a strip groove, the sliding frame plates are respectively slidably connected to the lower ends of the outer side surfaces of the T-shaped support rods on the same side, the interior of the sliding frame plates are longitudinally slidably connected to the limiting plates, and conical grooves matching the limiting plates are evenly spaced at the lower end edges of the relative inner side surfaces of the two T-shaped support rods. The middle parts of the limiting plates are rotatably connected with studs, the outer ends of the studs pass through the corresponding circular holes in the middle of the outer side surfaces of the sliding frame plates and are threadedly connected with nuts at the ends, the studs are located inside the strip grooves corresponding to the lower ends of the T-shaped support rods, and can limit the maximum adjustment position of the assembly line.

[0014] As an improvement of the present invention, the upper surface of the sliding frame plate is provided with a rubber pad to play a buffering role for the upper structure.

[0015] As an improvement of the present invention, support sleeves are symmetrically arranged at the lower ends of the relative inner sides of the fixed bracket, and an insertion rod is symmetrically arranged at the middle part of the sliding bracket, and the left and right ends of the insertion rod are respectively inserted into the corresponding support sleeves on the same side, so as to facilitate the limiting fixation of the support sleeve and the insertion rod.

[0016] As an improvement of the present invention, the inner end of the support sleeve is threadedly connected with a threaded sleeve, and the corresponding support sleeves are laterally provided with notches at equal angles relative to the inner edge surface. The inclined surface of the inner wall of the threaded sleeve is matched with the protrusion on the outer side surface of the support sleeve to facilitate leveling of the upper structure.

[0017] As an improvement of the present invention, the lower ends of the fixed bracket and the sliding bracket are symmetrically provided with adjustment screw holes, the insides of the adjustment screw holes are threadedly connected with foot pads, the upper ends of the foot pads are threadedly connected with adjustment nuts, and the adjustment nuts are respectively in contact with the bottom surfaces of the corresponding fixed bracket and sliding bracket.

[0018] Compared with the prior art, the embodiments of the present invention mainly have the following beneficial effects:

[0019] 1. When the length of the conveyor belt needs to be adjusted, move the two fixed brackets closer to each other, and at the same time, move the two bridge rods in the middle downward relative to the inner ends, and the rotating shaft at the center moves downward along the corresponding strip opening in the middle of the sliding bracket. At the same time, the conveyor roller at the center moves downward synchronously and presses the bottom end of the conveyor belt downward, so as to adjust the length of the conveyor belt. At the same time, the limiting rollers between the fixed blocks are in contact with the bottom surface of the conveyor belt, which can limit the left and right sides of the lower end of the conveyor belt, ensuring the normal transmission of the conveyor rollers and the conveyor belt at the left and right ends, and has stronger applicability.

[0020] 2. When adjusting the length of the conveyor belt, first turn the limit bolt to move the gear connected to the outer end of the limit bolt out of the step groove, and then adjust the length of the conveyor belt. At the same time, the bridge rods on the left and right sides are approached, and the limit bolts are driven to approach along the step groove through the corresponding rotating shaft. When the conveyor belt is adjusted to a suitable position, turn the limit bolt to tighten the limit bolt and the screw hole corresponding to the outer end of the rotating shaft, and at the same time press the gear into the inside of the step groove so that the gear engages with the tooth groove corresponding to the inner wall of the step groove, so that the limit bolt and the T-shaped support rod are relatively fixed, thereby supporting the bridge rods at both ends, making the adjusted conveyor belt more stable.

[0021] 3. When adjusting the length of the conveyor belt, first slide the sliding frame plate down a certain length along the T-shaped support rod. The strip groove will avoid the stud. Then turn the nut on the outer end of the stud to make the stud drive the limit plate inside the frame plate closer to the T-shaped support rod until the conical protrusion on the outer side of the limit plate is inserted into the corresponding conical groove on the inner side of the corresponding T-shaped support rod, thereby limiting the frame plate. When the frame plate is fixed, move the conveyor belt so that the middle bridge rod moves down relative to the inner end and contacts the rubber pad on the upper surface of the frame plate on the same side, thereby limiting the maximum adjustment position of the conveyor belt, facilitating the rapid and precise adjustment of the conveyor belt and making it more convenient to use.

DETAILED DESCRIPTION

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs; the terms used herein in the specification of the application are for the purpose of describing specific embodiments only and are not intended to limit the present invention. Reference to "embodiments" herein means that the specific features, structures, or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] Embodiment 1 of an adjustable length production line of the present invention

[0034] The invention discloses an adjustable-length production line comprising a conveying assembly 1 and a T-shaped support rod 2;

[0035] Conveying component 1: The lower surface of the conveying component 1 is symmetrically provided with a fixed bracket 3, and the middle part of the conveying component 1 is located inside the strip-shaped opening symmetrically provided in the middle part of the sliding bracket 4;

[0036] T-shaped support rod 2: symmetrically arranged at the lower end of the sliding bracket 4, the upper end of the T-shaped support rod 2 is symmetrically arranged with a limit assembly 21 installed in cooperation with the conveying assembly 1, and the lower end of the T-shaped support rod 2 is provided with a second limit assembly 22.

[0037] The length of the assembly line can be adjusted quickly and accurately, and the adjusted assembly line support is more stable, more applicable, and more convenient to use.

[0038] The conveying assembly 1 includes a bridge rod 101, a conveying roller 102, a conveyor belt 103 and a rotating shaft 104. The bridge rod 101 is symmetrically arranged front to back. The two adjacent bridge rods 101 on the same side are rotatably connected by the rotating shaft 104. A conveying roller 102 is arranged between the two corresponding rotating shafts 104 in the longitudinal direction. The conveying rollers 102 on the left and right sides are connected by transmission through the conveyor belt 103. The upper ends of the fixed brackets 3 are fixedly connected to the corresponding bridge rods 101 on the same side through angle locks. The two rotating shafts 104 at the center are respectively located in the corresponding strip openings in the middle of the sliding bracket 4. The outer side surfaces of the conveying rollers 102 are symmetrically arranged with annular grooves 11 front to back, and the inner side surfaces of the conveyor belt 103 are symmetrically arranged with convex strips matching the annular grooves 11. It also includes fixed blocks 7, which are respectively arranged on the bottom surfaces of the bridge rods 101 at the left and right ends. The two corresponding fixed blocks 7 front and back are rotatably connected with a limiting roller 8.

[0039] The bridge rods 101 at the left and right ends are fixed to the corresponding upper ends of the fixed brackets 3 by angle locks. When the length of the conveyor belt 103 needs to be adjusted, the two fixed brackets 3 are moved closer to each other, and the two bridge rods 101 in the middle are moved downward relative to the inner ends. The rotating shaft 104 at the center moves downward along the corresponding strip opening in the middle of the sliding bracket 4. At the same time, the conveying roller 102 at the center moves downward synchronously and presses the bottom end of the conveyor belt 103 downward, so as to adjust the length of the conveyor belt 103. At the same time, the limiting rollers 8 between the fixed blocks 7 are in contact with the bottom surface of the conveyor belt 103, which can limit the left and right sides of the lower end of the conveyor belt 103, ensuring the normal transmission of the conveying rollers 102 and the conveyor belt 103 at the left and right ends. When the conveyor belt 103 is transmitting, the convex strip on the inner side of the conveyor belt 103 is located inside the annular groove 11 corresponding to the outer side of the conveying roller 102, which can limit the conveyor belt 103.

[0040] The lower ends of the relative inner sides of the fixed bracket 3 are symmetrically provided with support sleeves 9, and the middle part of the sliding bracket 4 is symmetrically provided with insertion rods 10. The left and right ends of the insertion rods 10 are respectively inserted into the corresponding support sleeves 9 on the same side. The inner ends of the support sleeves 9 are threadedly connected with threaded sleeves 92. The corresponding support sleeves 9 are laterally provided with notches 91 at equal angles relative to the inner edges. The inclined surface of the inner wall of the threaded sleeves 92 is matched with the protrusion on the outer side of the support sleeve 9.

[0041] When the two fixed brackets 3 approach each other, the supporting sleeve 9 and the insertion rod 10 corresponding to the lower end of the sliding bracket 4 slide relative to each other, which guides the movement of the fixed bracket 3. When the fixed bracket 3 moves to a suitable position, the threaded sleeve 92 at the end of the supporting sleeve 9 is rotated, and the inclined surface of the inner wall of the threaded sleeve 92 contacts the protrusion at the end of the outer side surface of the supporting sleeve 9. Because the outer edge surface of the supporting sleeve 9 is evenly provided with notches 91, the rotation of the threaded sleeve 92 causes the outer edge surface of the supporting sleeve 9 to deform and squeeze toward the center, and the supporting sleeve 9 and the insertion rod 10 are fixed under the action of friction, which can limit the adjusted fixed bracket 3.

[0042] The lower ends of the fixed bracket 3 and the sliding bracket 4 are symmetrically provided with adjustment screw holes 5, the insides of the adjustment screw holes 5 are threadedly connected with foot pads 6, and the upper ends of the foot pads 6 are threadedly connected with adjustment nuts 61, which are in contact with the corresponding bottom surfaces of the fixed bracket 3 and the sliding bracket 4 respectively.

[0043] Turn the adjusting nut 61 on the upper end of the foot 6 to a suitable position, and then turn the foot 6 to adjust the length of the foot 6 exposed from the lower end of the fixed bracket 3 and the sliding bracket 4 until the adjusting nut 61 contacts the corresponding bottom end of the fixed bracket 3 and the sliding bracket 4, so as to facilitate leveling of the upper structure.

[0044] Embodiment 2 of a pipeline with adjustable length according to the present invention

[0045] In an adjustable-length production line of the present invention: a limiting assembly 21 includes a limiting bolt 211, a gear 212 and a step groove 213, the step groove 213 is symmetrically arranged at the upper end of the outer surface of the T-shaped support rod 2, the inner part of the step groove 213 is movably inserted with the limiting bolt 211, the end of the limiting bolt 211 is threadedly connected to the screw hole arranged at the outer end of the corresponding rotating shaft 104 on the same side, the outer end of the limiting bolt 211 is rotatably connected with the gear 212, and the inner wall of the step groove 213 is evenly provided with tooth grooves matching the gear 212.

[0046] When adjusting the length of the conveyor belt 103, first rotate the limit bolt 211 to make the gear 212 connected to the outer end of the limit bolt 211 move out of the step groove 213, and then adjust the length of the conveyor belt 103. At the same time, the bridge rods 101 on the left and right sides approach each other, and the limit bolt 211 is driven to approach each other along the step groove 213 through the corresponding rotating shaft 104. When the conveyor belt 103 is adjusted to a suitable position, rotate the limit bolt 211 to tighten the limit bolt 211 and the screw hole corresponding to the outer end of the rotating shaft 104, and at the same time press the gear 212 into the interior of the step groove 213, so that the gear 212 is engaged with the tooth groove corresponding to the inner wall of the step groove 213, so that the limit bolt 211 and the T-shaped support rod 2 are relatively fixed, thereby supporting the bridge rods 101 at the left and right ends, so that the adjusted conveyor belt 103 is more stable.

[0047] Embodiment 3 of a pipeline with adjustable length according to the present invention

[0048] In an adjustable-length production line of the present invention: the second limiting component 22 includes a sliding frame plate 221, a stud 222, a limiting plate 223 and a strip groove 224, the sliding frame plates 221 are respectively slidably connected to the lower ends of the outer side surfaces of the T-shaped support rods 2 on the same side, the interior of the sliding frame plates 221 are longitudinally slidably connected to the limiting plates 223, and conical grooves matching the limiting plates 223 are evenly spaced at the lower end edges of the relative inner side surfaces of the two T-shaped support rods 2, the middle parts of the limiting plates 223 are rotatably connected with the studs 222, the outer ends of the studs 222 pass through the corresponding circular holes in the middle of the outer side surfaces of the sliding frame plates 221 and are threadedly connected with nuts at the ends, and the upper surfaces of the sliding frame plates 221 are provided with rubber pads 12.

[0049] When adjusting the length of the conveyor belt 103, first slide the sliding frame plate 221 down a certain length along the T-shaped support rod 2, and the strip groove 224 will avoid the stud 222. Then turn the nut on the outer end of the stud 222 to make the stud 222 drive the limit plate 223 inside the frame plate 221 closer to the T-shaped support rod 2 until the conical protrusion on the outer side of the limit plate 223 is inserted into the corresponding conical groove on the inner side of the corresponding T-shaped support rod 2, thereby limiting the frame plate 221. When the frame plate 221 is fixed, the conveyor belt 103 is moved so that the middle bridge rod 101 moves downward relative to the inner end and contacts the rubber pad 12 on the upper surface of the frame plate 221 on the same side, thereby limiting the maximum adjustment position of the conveyor belt 103, facilitating the rapid and accurate adjustment of the conveyor belt 103, and making it more convenient to use.
