[0007] In order to achieve the above-mentioned purpose, the utility model provides a kind of belt detection tension adjusting mechanism, including transmission set, fixed seat, the mechanism further includes: tension fine adjustment component;

[0008] The tension fine adjustment component includes: power roller, driven roller, tension spring and adjusting stud;Wherein,

[0009] The fixed seat is provided with a power roller horizontally and rotatably, and a rotating rod is provided horizontally and rotatably on the fixed seat beside the power roller, two assembly seats are fixedly arranged on the shaft of the rotating rod by quick release parts, two hinged plates are arranged spaced apart and hinged on the two assembly seats, and a driven roller capable of abutting on the power roller is arranged horizontally and rotatably between the two hinged plates, a through hole is vertically arranged in each assembly seat for the adjusting stud to pass through, the adjusting stud passes through the through hole and is screwed at the stud hole vertically arranged in the corresponding hinged plate, and a tension spring is sleeved on each adjusting stud between the hinged plate and the assembly seat, and the two ends of each tension spring abut on the hinged plate and the assembly seat respectively.

[0010] Preferably, the quick release part includes a bolt.

[0011] An avoiding hole is horizontally arranged in each assembly seat for the rotating rod to pass through, and a cutout is horizontally arranged in the end of each assembly seat away from the driven roller and communicated with the avoiding hole, a through hole is arranged in the top of the assembly seat and communicated with the cutout and for the bolt to pass through, a bolt hole is arranged in the cutout directly below the through hole and threaded with the bolt, and the bolt passes through the through hole and is screwed in the bolt hole, so that the assembly seat tightly holds the rotating rod.

[0012] Preferably, the width of the cutout is smaller than the diameter of the rotating rod.

[0013] Preferably, a manipulating rod is fixedly arranged on the rotating rod away from the fixed seat.

[0014] Preferably, the power roller and the driven roller are polyurethane rollers.

[0015] Preferably, the transmission group comprises a first transmission group, a second transmission group and a third transmission group, and the fabric belt sequentially passes through the first transmission group, the second transmission group and the third transmission group and then leaves the winding after passing through the tension fine adjustment assembly, wherein,

[0016] The first transmission group comprises a plurality of first transmission rollers which are spaced apart and horizontally rotatable arranged on the fixed seat, and the heights of adjacent two first transmission rollers are different, and the second transmission group and the third transmission group are spaced apart and respectively arranged below the first transmission group, and the second transmission group and the third transmission group each comprise at least one second rotation roller and a third transmission roller which are horizontally and rotatably arranged on the fixed seat.

[0017] According to the above technical scheme, the fabric belt detection tension adjustment mechanism provided by the utility model has the following beneficial effects in use:

[0018] (1) The fixed seat is horizontally fixed with a power motor, and the power motor is coaxially connected with the end of the power roller through a shaft coupling, and the power roller is driven to rotate by starting the power motor. The fabric belt passes through the transmission group, the visual detection device and the tension fine adjustment assembly in sequence through the existing disclosed unwinding device (the existing disclosed tape feeder), and is wound by the existing disclosed winding device (or is stored by the existing disclosed storage device). In use, the tension of the fabric belt is preliminarily adjusted by adjusting the rotating speed of the transmission group and the power roller, and when different widths or different types or different widths of fabric belts are detected, the tension of the fabric belt can also be fine adjusted only by the tension fine adjustment assembly, so as to avoid that the fabric belt is too loose during detection.

[0019] (2) Specifically, the fine adjustment mode is that since the two adjusting studs pass through the through holes formed in the top of the two assembly seats and are screwed in the stud holes in the two hinge plates, the depth of the adjusting stud in the stud hole in the hinge plate can be changed by rotating the adjusting stud, so as to adjust the tension of the tension spring sleeved on the shaft body, adjust the tension of the driven roller on the fabric belt, and thus adjust the tension of the fabric belt.

[0020] When the fabric belt is tensioned, the adjusting stud can be rotated to continue to penetrate into the stud hole of the hinge plate, so that the tension spring sleeved thereon is continuously compressed to increase the tension of the tension spring, and at the same time, the gap between the driven roller and the power roller is increased to avoid the fabric belt between them from being excessively tensioned and broken.

[0021] Conversely, when the belt is loosened, the adjusting stud is rotated reversely to move its bottom away from the threaded hole of the hinged plate to reduce the tension of the tension spring, while the driven roller approaches the driving roller to make the gap between them smaller or even the driven roller abuts against the driving roller, so that the belt passing between them is in tension.

[0022] (3) Since the tension of the tension spring can be adjusted by rotating the adjusting stud, during long-term use, the adjusting stud can be rotated to continue to extend into the threaded hole of the hinged plate, so that the tension spring thereon continues to be compressed to ensure its initial elasticity, thereby avoiding the fatigue of the tension spring affecting its elasticity after long-term use, improving the use effect of the entire tension adjusting mechanism, and the adjustment process is relatively simple and convenient to use.

[0023] In summary, the tension of the belt is preliminarily adjusted by adjusting the rotating speeds of the transmission rollers of the transmission group and the driving roller of the tension fine adjustment mechanism, and the belt is fine-adjusted again by the tension fine adjustment mechanism, so that the belt always maintains a certain tension, thereby improving the use effect of the entire tension adjusting mechanism, and the adjustment process is relatively simple and convenient to use.

DETAILED DESCRIPTION

[0032] The specific embodiments of the utility model are described in detail below in combination with the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0033] As Figures 1-4 indicated, the utility model provides a kind of braid detection tension adjusting mechanism, including transmission group, fixed seat 1, the mechanism further includes: tension fine adjustment assembly 5;

[0034] The tension fine adjustment assembly 5 includes: power roller 501, driven roller 502, tension spring 503 and adjusting stud 504;Wherein,

[0035] The fixed seat 1 is horizontally and rotatably provided with power roller 501, the fixed seat 1 is horizontally and rotatably provided with rotating rod 13 on the side of power roller 501, and two assembly seats 14 are fixedly arranged on the shaft by quick release member, two hinged plates 12 are hingedly arranged on two assembly seats 14, and driven roller 502 that can be abutted on power roller 501 is rotatably arranged between the two, the top of each assembly seat 14 is vertically provided with the through hole for adjusting stud 504, adjusting stud 504 passes through the through hole and is screwed in the stud hole 7 vertically passing through in the corresponding hinged plate 12, and tension spring 503 is sleeved on each adjusting stud 504 between hinged plate 12 and assembly seat 14, and the two ends of each tension spring 503 are respectively abutted on hinged plate 12 and assembly seat 14.

[0036] In the above scheme, the fixed seat 1 is horizontally fixed with power motor, and the power motor is coaxially connected with the end of power roller 501 through shaft coupling, and the power roller 501 is driven to rotate by starting power motor. Figure 1As shown, the fabric belt is sequentially passed through the transmission group, the visual detection device and the tension fine adjustment assembly 5 by the existing disclosed unwinding device (the existing disclosed fabric belt machine), and then is wound by the existing disclosed winding device (or is stored by the existing disclosed storage device). In use, the tension of the fabric belt is preliminarily adjusted by adjusting the rotating speed of the transmission group and the power roller 501. When different widths or different types or different widths of fabric belts are detected, the tension of the fabric belt can also be fine adjusted only by the tension fine adjustment assembly 5 to avoid that the fabric belt is too loose during the detection process.

[0037] Specific fine adjustment mode: since the two adjusting studs 504 respectively pass through the through holes opened at the top of the two assembly seats 14 and are screwed into the stud holes 7 on the two hinged plates 12, the adjusting studs 504 can be rotated to change the depth of the adjusting studs 504 into the stud holes 7 on the hinged plates 12 to adjust the tensioning degree of the tensioning springs 503 sleeved on the shaft bodies of the adjusting studs 504, thereby adjusting the tensioning degree of the driven rollers 502 on the fabric belt, and adjusting the tension of the fabric belt.

[0038] When the fabric belt is tensioned, the adjusting studs 504 can be rotated to continue to penetrate into the stud holes 7 of the hinged plates 12, so that the tensioning springs 503 sleeved thereon are continuously compressed to increase the tensioning degree of the tensioning springs 503, and at the same time, the gap between the driven rollers 502 and the power roller 501 is increased to avoid the fabric belt passing therebetween from being excessively tensioned and broken.

[0039] Conversely, when the fabric belt is loose, the adjusting studs 504 are reversely rotated to move the bottoms thereof away from the stud holes 7 of the hinged plates 12 to reduce the tensioning degree of the tensioning springs 503, and at the same time, the driven rollers 502 approach the power roller 501 to reduce the gap therebetween or even abut against the power roller 501 to make the fabric belt passing therebetween in a tensioned state.

[0040] Since the tensioning degree of the tensioning springs 503 can be adjusted by rotating the adjusting studs 504, during long-term use, the adjusting studs 504 can be rotated to continue to penetrate into the stud holes 7 of the hinged plates 12 to continuously compress the tensioning springs 503 thereon to ensure the initial elasticity thereof, thereby avoiding that the tensioning springs 503 are fatigued to affect the elasticity thereof after long-term use, improving the use effect of the entire tension adjustment mechanism, and the adjustment process is relatively simple and convenient to use.

[0041] In summary, the tension of the belt is preliminarily adjusted by adjusting the rotating speeds of the transmission rollers of the transmission set and the power roller 501 of the tension fine adjustment mechanism 5, and the belt is fine-adjusted again by the tension fine adjustment mechanism 5, so that the belt always maintains a certain tension, thereby improving the use effect of the whole tension adjustment mechanism, and the adjustment process is relatively simple and convenient to use.

[0042] In a preferred embodiment of the utility model, the quick release part comprises a bolt 6, wherein,

[0043] Each assembly seat 14 is horizontally provided with an avoiding hole 8 through which the rotating rod 13 passes, and the end of each assembly seat 14 away from the driven roller 502 is horizontally provided with a cutout 9 in communication with the avoiding hole 8, the top of the assembly seat 14 is provided with a through hole 10 in communication with the cutout 9 and through which the bolt 6 passes, the cutout 9 directly below the through hole 10 is further provided with a bolt hole 11 in threaded connection with the bolt 6, and the bolt 6 passes through the through hole 10 and is screwed in the bolt hole 11, so that the assembly seat 14 is tightly held on the rotating rod 13.

[0044] In the above scheme, as shown in Figure 2 and 3 when in use, the two assembly seats 14 are clamped on the rotating rod 13 respectively, and the two bolts 6 pass through the through holes 10 on the two assembly seats 14 respectively, pass through the respective cutouts 9 and are screwed in the bolt holes 11, so that the assembly seats 14 are tightly held on the rotating rod 13, thereby quickly completing the assembly work and facilitating disassembly, so as to be convenient for replacement and maintenance in the later period.

[0045] In a preferred embodiment of the utility model, the width of the cutout 9 is smaller than the diameter of the rotating rod 13.

[0046] In the above scheme, the cutout 9 is prevented from being too large to greatly reduce the strength of the assembly seat 14.

[0047] In a preferred embodiment of the utility model, the rotating rod 13 away from the fixed seat 1 is fixedly provided with a control rod 15.

[0048] In the above scheme, the rotating rod 13 is conveniently rotated through the control rod 15, so that the rotating rod 13 can drive the driven roller 502 to abut against the power roller 501 or away from the power roller 501 in the process of rotation.

[0049] In a preferred embodiment of the utility model, the power roller 501 and the driven roller 502 are polyurethane rollers.

[0050] In the above scheme, the polyurethane glue roller is adopted, which has high strength and wear resistance, thereby prolonging the service life.

[0051] In a preferred embodiment of the utility model, the transmission group includes: a first transmission group 2, a second transmission group 3 and a third transmission group 4, the braid passes through the first transmission group 2, the second transmission group 3 and the third transmission group 4 in turn and then leaves the winding after passing through the tension fine adjustment assembly 5, wherein,

[0052] The first transmission group 2 includes: a plurality of first transmission rollers which are spaced apart and horizontally rotatable arranged on the fixed seat 1, and the heights of the two adjacent first transmission rollers are different, the second transmission group 3 and the third transmission group 4 are spaced apart and located below the first transmission group 2 respectively, and the second transmission group 3 and the third transmission group 4 each include: at least one second rotating roller and third transmission roller which are horizontally and rotatably arranged on the fixed seat 1.

[0053] In the above scheme, one of the first transmission rollers 2 of the first transmission group 2 is connected together with a first transmission motor which is horizontally fixed on the fixed seat 1 through a shaft coupling, and the first transmission motor drives the first transmission roller 2 connected thereto to rotate, and the second rotating roller and the third transmission roller are coaxially connected together with a second transmission motor and a third transmission motor which are horizontally fixed on the fixed seat 1 through shaft couplings respectively, and the first transmission motor, the second transmission motor and the third transmission motor correspondingly drive the transmission rollers of the first transmission group 2, the second transmission group 3 and the third transmission group 4 to rotate respectively.

[0054] Since different types of braids need to be adapted to different tensions, and the same type of braid also needs to be adapted to different tensions due to the width and elasticity difference, and the adjustment of the tension is related to the rotating speed of each transmission motor, therefore, the tension of the above braid can be preliminarily adjusted by adjusting the speed of the first transmission motor, the second motor, the third transmission motor and the power motor. When detecting the above different types and different widths of braids, the tension fine adjustment mechanism 5 can also be used for fine adjustment, thereby improving the use effect of the tension mechanism.

[0055] In summary, the braid detection tension adjustment mechanism provided by the utility model overcomes the problem that the spring of the tension adjustment mechanism in the prior art is fatigued after long-term use, the elasticity of the spring is insufficient, and the use effect of the tension adjustment mechanism is poor.
