Description
Technical Field
[0001] This utility model relates to the field of spring bed mesh production technology, and in particular to a spring screening and turning device. Background Technology
[0002] Spring mattresses are generally composed of numerous springs connected horizontally and vertically. The process of connecting these springs into a whole is crucial in the production of spring mattresses; this process is called spring stringing. Between the spring strings, the numerous springs need to be divided into multiple rows, and each spring needs to be screened out from the rest to facilitate feeding into the spring stringing equipment. Current equipment typically only includes a conveyor plate and spring baffles. The conveyor plate is mounted on a conveyor belt, and batches of springs are placed on the conveyor belt. The conveyor plate divides the springs into multiple rows, and then the spring baffles block the springs at the discharge end. When feeding is needed, the spring baffles actuate to release individual springs, and then rise again to block subsequent springs. The biggest problem with this structure is that the use of spring baffles makes it impossible to precisely control the stopping and discharge of springs. Furthermore, the rising and falling strokes of the spring baffles are long, resulting in long usage times, and it is impossible to perform efficient automatic screening of the springs after they have been sorted. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide a spring screening and turning device that can accurately control the discharge of the spring and has a high screening efficiency.
[0004] To solve the above-mentioned technical problems, this utility model provides a spring screening and flipping device, including a screening rotation drive, a screening rotation shaft that is pulverizedly connected to the screening rotation drive, and a plurality of screening clamping mechanisms disposed on the screening rotation shaft. The screening rotation drive can drive the screening rotation shaft to rotate, thereby causing the screening clamping mechanisms to swing.
[0005] The screening clamping mechanism includes a screening clamping drive, a screening clamping platform, and a screening clamping block. The screening clamping drive is connected to the screening clamping block in a transmission manner. The screening clamping drive can drive the screening clamping block to swing in a direction close to or away from the screening clamping platform. When the screening clamping block and the screening clamping platform are close to each other, they can clamp the spiral wire of the spring.
[0006] As an improvement to the above solution, the screening clamping mechanism further includes a first extending arm, one end of which is fixed to the screening rotating shaft and extends outward toward the periphery of the screening rotating shaft. The screening clamping platform is located at the other end of the first extending arm, and the end of the screening clamping block is provided with a pressing part, which can abut against the screening clamping platform.
[0007] As an improvement to the above solution, the screening clamping table has a first clamping surface in the middle and a second clamping surface in the pressing part. The first clamping surface and the second clamping surface can abut against each other. The first clamping surface has a screening first locking groove and the second clamping surface has a screening second locking groove. The screening second locking groove is located on the side of the pressing part near the screening clamping table. The positions of the screening first locking groove and the screening second locking groove are corresponding. When the screening first locking groove and the screening second locking groove are close to each other, they can clamp the spiral wire of the spring.
[0008] As an improvement to the above solution, the screening clamping mechanism further includes a second extension arm, one end of which is fixed to the screening rotating shaft and extends toward the periphery of the screening rotating shaft, and the fixed end of the screening clamping drive is fixed to the second extension arm.
[0009] As an improvement to the above solution, the first clamping surface is inclined, and the inclination direction of the first clamping surface is from the side near the first extended arm to the side near the second extended arm; the second clamping surface is inclined, and the inclination direction of the second screening groove is from the side near the first extended arm to the side near the second extended arm, and the second screening groove is through-hole, with the through-hole direction perpendicular to the feeding direction of the spring, so as to facilitate the engagement of the second screening groove with the spiral wire of the spring.
[0010] As an improvement to the above solution, the screening clamping mechanism further includes a swing arm, which includes a first connecting section and a second connecting section. The movable end of the screening clamping drive is hinged to the first connecting section. The second connecting section extends from the second extending arm toward the direction of the first extending arm. The second connecting section is connected to the screening clamping block. The side of the swing arm is hinged to the side of the second extending arm. The screening clamping drive can drive the swing arm to swing on the side of the first extending arm and the second extending arm, so that the screening clamping block moves closer to or away from the screening clamping table.
[0011] As an improvement to the above solution, the swing arm further includes a crankshaft section, the two ends of which are connected to the first connecting section and the second connecting section respectively, and the crankshaft section extends from the first connecting section and passes around the screening rotation shaft.
[0012] As an improvement to the above solution, the screening clamping mechanism further includes a limiting platform, which is fixed on the screening rotating shaft. The limiting platform is provided with a limiting protrusion that extends toward the side where the first extending arm is located. The swing arm is provided with a limiting groove, the width of which corresponds to the width of the limiting protrusion. The limiting protrusion can be inserted into the limiting groove, and when the swing arm swings, the limiting protrusion can limit the limiting groove.
[0013] As an improvement to the above solution, the spring screening and turning device further includes a support frame, which is fixed to the first extended arm. The support frame has a support plate in the middle, which is located on the side of the screening clamping table and the screening clamping block. When the screening clamping block and the screening clamping table approach each other to clamp the spiral wire of the spring, the side of the spring can abut against the support plate.
[0014] As an improvement to the above solution, the movable end of the screening rotation drive is coaxially connected to the screening rotation shaft, and the number of screening clamping mechanisms is multiple and evenly distributed along the screening rotation shaft, with the extension directions of the swing arms of adjacent screening clamping mechanisms staggered from each other.

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.
[0022] See Figure 1 and Figure 2 This utility model discloses a spring screening and flipping device, including a screening rotation drive 1, a screening rotation shaft 2 driven by the screening rotation drive 1, and a plurality of screening clamping mechanisms 4 disposed on the screening rotation shaft 2. The screening rotation drive 1 is driven by the screening rotation shaft 2, and the screening clamping mechanisms 4 are disposed on the screening rotation shaft 2. The screening rotation drive 1 can drive the screening rotation shaft 2 to rotate. When the screening rotation shaft 2 rotates, it can drive the screening clamping mechanisms 4 to swing. After rotating to one angle, it can clamp the spring 5. After clamping, it can rotate to another angle and place the spring 5 to the next station for discharge.
[0023] To achieve clamping, the screening clamping mechanism 4 includes a screening clamping drive 41, a screening clamping platform 42, and a screening clamping block 43. The screening clamping drive 41 is connected to the screening clamping block 43. The screening clamping drive 41 can drive the screening clamping block 43 to swing towards or away from the screening clamping platform 42. When the screening clamping block 43 is close to the screening clamping platform 42, the screening clamping block 43 and the screening clamping platform 42 can clamp the spring 5. Then, the screening rotating shaft 2 rotates, causing the screening clamping block 43 and the screening clamping platform 42 to swing to another angle. After that, the screening clamping block 43 is driven away from the screening clamping platform 42, releasing the spring 5 and placing the spring 5 in the next working position.
[0024] The beneficial effects of this utility model embodiment are as follows:
[0025] This utility model embodiment of the spring screening and turning device includes a screening rotation drive 1, a screening rotation shaft 2, and multiple screening clamping mechanisms 4. The screening rotation drive 1 can drive the screening rotation shaft 2 to rotate, thereby causing the screening clamping mechanisms 4 to swing. The spring screening and turning device is located on the side of the spring 5 discharge port. The screening clamping mechanism 4 includes a screening clamping drive 41, a screening clamping platform 42, and a screening clamping block 43. When the spring 5 needs to be discharged, the screening clamping drive 41 can drive the screening clamping block 43 to swing towards or away from the screening clamping platform 42. When the screening clamping block 43 and the screening clamping platform 42 are close to each other, they can clamp the spiral wire of the spring 5. Through clamping, the discharge of the spring 5 can be precisely controlled without a long waiting time. With the cooperation of multiple screening clamping mechanisms 4, multiple rows of springs 5 can be screened, so the screening efficiency is high.
[0026] Specifically, see Figure 2 The screening and clamping mechanism 4 further includes a first extending arm 45. One end of the first extending arm 45 is fixed to the screening rotating shaft 2 and extends outward toward the periphery of the screening rotating shaft 2. The other end of the first extending arm 45 is provided with a screening clamping platform 42. The screening clamping platform 42 is fixedly installed and can provide a fixed platform for gripping the spring 5. The screening clamping block 43 is a movable part that can cooperate with the screening clamping platform 42 to clamp the spring 5. The end of the screening clamping block 43 is provided with a pressing part 44, which can abut against the screening clamping platform 42 to clamp the spiral wire of the spring 5. In order to clamp the wire of the spring 5, the screening clamping platform 42 is provided with a first clamping surface 421 in the middle, and the pressing part 44 is provided with a second clamping surface 441. The first clamping surface 421 and the second clamping surface 441 can abut against each other to clamp the spiral wire of the spring 5. Specifically, the first clamping surface 421 is provided with a first screening groove 422, which is recessed inward. The second clamping surface 441 is provided with a second screening groove 442, which is located on the side of the pressing part 44 near the screening clamping table 42. The second screening groove 442 is recessed inward. The positions of the first screening groove 422 and the second screening groove 442 are corresponding. When the first screening groove 422 and the second screening groove 442 are close to each other, they form a receiving space. The wire of the spring 5 can be placed in this receiving space, so that the spiral wire of the spring 5 can be clamped.
[0027] The screening clamping mechanism 4 further includes a second extending arm 46, one end of which is fixed to the screening rotating shaft 2 and extends outward toward the periphery of the screening rotating shaft 2. The fixed end of the screening clamping drive 41 is fixed to the second extending arm 46, providing a fixed space for the screening clamping drive 41. The screening clamping drive 41 is preferably a linear cylinder.
[0028] See Figure 3 The first clamping surface 421 is inclined, with the inclination direction from the side near the first extending arm 45 towards the side near the second extending arm 46. The second clamping surface 441 is also inclined, and the inclination direction of the second screening groove 442 is from the side near the first extending arm 45 towards the side near the second extending arm 46. The second screening groove 442 is through-hole, with its through-hole direction perpendicular to the feeding direction of the spring 5, so that the second screening groove 442 can engage with the spiral thread of the spring 5. The inclined first screening groove 422 and the second screening groove 442 can make the spring 5 tend to leave the conveyor belt when the second screening groove 442 engages with the spiral thread of the spring 5, thereby facilitating the rapid departure of the spring 5 from the discharge end of the conveyor belt and improving the success rate of screening out a single spring 5.
[0029] To drive the screening clamping block 43, the screening clamping mechanism 4 further includes a swing arm 47. The swing arm 47 includes a first connecting section 471 and a second connecting section 472. The movable end of the screening clamping drive member 41 is hinged to the first connecting section 471. The second connecting section 472 extends from the second extending arm 46 toward the first extending arm 45 and is connected to the screening clamping block 43. The side of the swing arm 47 is hinged to the side of the second extending arm 46. Thus, when the screening clamping drive member 41 extends or retracts, the movable end of the screening clamping drive member 41 can drive the swing arm 47 to swing around the hinge point between the swing arm 47 and the second extending arm 46, while the swing arm 47 swings between the sides of the first extending arm 45 and the second extending arm 46.
[0030] The swing arm 47 further includes a crankshaft section 473, the two ends of which are connected to the first connecting section 471 and the second connecting section 472, respectively. The crankshaft section 473 extends from the first connecting section 471 and bypasses the screening rotating shaft 2. Because the crankshaft section 473 bypasses the screening rotating shaft 2, the swing of the swing arm 47 will not interfere with the screening rotating shaft 2, and the screening clamping block 43 has sufficient space to approach or move away from the screening clamping table 42, enabling it to generate clamping force or release the spring 5.
[0031] See Figure 4 The screening clamping mechanism 4 further includes a limiting platform 48, which is fixed on the screening rotating shaft 2 and can rotate with the screening rotating shaft 2. The limiting platform 48 is fixedly set relative to the swing arm 47, and the limiting platform 48 is provided with a limiting protrusion 481. The limiting protrusion 481 extends toward the side where the first extending arm 45 is located. The swing arm 47 is provided with a limiting groove 474, the width of which corresponds to the width of the limiting protrusion 481. When the swing arm 47 swings, the limiting protrusion 481 can be inserted into the limiting groove 474. At this time, the limiting protrusion 481 can limit the limiting groove 474, thereby limiting the swing direction of the swing arm 47 and ensuring stable swing.
[0032] In addition, see Figure 2 The spring screening and turning device further includes a support frame 3, which is fixed to the first extended arm 45. A support plate 31 is provided in the middle of the support frame 3, located on the side of the screening clamping table 42 and the screening clamping block 43. When the screening clamping block 43 and the screening clamping table 42 approach each other to clamp the spiral wire of the spring 5, the side of the spring 5 can abut against the support plate 31. After clamping the spring 5, the screening rotation drive 1 drives the screening rotation shaft 2 to rotate downwards by a certain angle. At this time, the support plate 31 is located below the spring 5, providing support for the spring 5. Combined with the screening clamping mechanism 4, it can stably clamp the spring 5 and prevent it from falling.
[0033] See Figure 1 The screening rotary drive 1 is preferably a rotary motor. The movable end of the screening rotary drive 1 is coaxially connected to the screening rotary shaft 2. Multiple screening clamping mechanisms 4 are evenly distributed along the screening rotary shaft 2. The number of screening clamping mechanisms 4 corresponds to the number of rows of springs 5. Each screening clamping mechanism 4 can screen each row of springs 5 individually. Referring to the figure, the extension directions of the swing arms 47 of adjacent screening clamping mechanisms 4 are staggered. This allows the second, fourth, and subsequent screening clamping mechanisms 4 to place the previously clamped spring 5 into the next station while the first, third, ..., screening clamping mechanism 4 is clamping the spring 5. Spring clamping and spring placement can be performed simultaneously, eliminating the need for subsequent equipment to wait for all springs 5 to be clamped before starting its operation, thus improving overall cycle efficiency.
[0034] The above are preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
