Abstract
Description
Technical Field
[0001] The invention relates to a spring mattress production device, in particular to a spring conveying mechanism. Background Art
[0002] The node positions of springs produced by spring production machines are determined at the beginning, but the original conveying equipment will disrupt the node positions of springs when conveying springs to the threading machine. Therefore, we need to locate the nodes of the springs once before they can be put on the threading machine. This requires adding a set of spring node positioning equipment, so the equipment becomes very complicated, and the spring nodes also need time to complete the positioning, which slows down the processing time, so it is necessary to improve it. Summary of the invention
[0003] In view of the deficiencies in the prior art, the present invention provides a spring conveying mechanism, in which the node positions of the springs will not change during the process of being transported to the mesh threading machine.
[0004] The technical solution adopted by the present invention to solve the technical problem is: a spring conveying mechanism, including a bracket, a channel formed by two mutually parallel baffles is arranged on the bracket, one end of the channel is connected to the outlet of the spring production equipment, and the other end of the channel is connected to the feeding port of the threading machine, the two ends of the spring are clamped on the baffle, and also includes a toggle mechanism for toggling the spring, the toggle mechanism includes two mutually parallel connecting rods, the two connecting rods are fixed together, and a plurality of toggle rods are arranged on the connecting rod, the toggle rods are matched with the nodes on the spring, and the number of the toggle rods corresponds to the number of springs in the channel, and also includes a driving mechanism for driving the toggle mechanism to move forward along the channel direction and driving the toggle mechanism to move up and down. When in use, the driving mechanism first drives the connecting rod to move forward in the direction of the channel toward one end of the threading machine, and during the forward process, the toggle rod toggles the node on the spring, so that the spring also moves forward, and when the spring moves forward to a certain distance, the connecting rod drops, then retreats, reaches the rear of the previous spring, and then repeats, thus completing the conveying of the spring. During the conveying process, the spring node is moved by the lever, so the position of the spring node remains unchanged during the forward movement of the spring, which saves the process of re-positioning the spring node by the subsequent mesh threading machine, greatly simplifies the structure, and also improves the processing efficiency.
[0005] The cam is connected to the second end of the driving mechanism, and the cam is connected to the first end of the driving mechanism, and the cam has the other end connected to the sliding block, and the sliding block is provided with a sliding groove, and the sliding groove is slidably connected to the second rod, and the second rod is fixed to the bracket, and the rotating shaft is hinged to one end of the rotating rod, and the other end of the rotating rod is hinged to one end of the third rod, and the other end of the third rod is hinged to the sliding block, and the baffle is slidably connected to the fourth rod, and the fourth rod is arranged parallel to the channel, and the bottom of the first rod is against the baffle, and the other end of the rotating rod is connected to the baffle through the fifth rod. When in use, the rotating shaft drives the rotating rod to rotate, and during the advancement stroke, the rotating rod drives the third rod to swing, and the third rod drives the sliding block to slide upward on the second rod, and the sliding block moves synchronously with the first rod and the connecting rod, and the toggle rod on the connecting rod drives the spring to move along the channel. During the advancement stroke, the high point of the baffle is always in contact with the bottom of the first rod, ensuring that the toggle device is in a high position. After being pushed to the position, the slider now retreats, but the baffle retreats later than the slider. Therefore, the first rod will slide from the highest point of the baffle to prevent the lever from toggling the spring at the rear during the retreat process. During the retreat stroke, the rotating rod drives the third rod to swing, and the third rod drives the slider to slide downward on the second rod, and the lever on the connecting rod retreats to the next spring. At this time, the first rod gradually moves to the highest point of the baffle, and the lever can contact the spring again, and then it is the advancement stroke again, and so on.
[0006] In the above technical solution, preferably, the connecting rods are fixed via a connecting column, and the first rod is fixed to the connecting column.
[0007] In the above technical solution, preferably, there are two connecting columns.
[0008] In the above technical solution, preferably, the channel is arranged obliquely upward.
[0009] In the above technical solution, preferably, the top of the lever has an inclined surface which is inclined upward along the channel.
[0010] The beneficial effect of the present invention is that when in use, the driving mechanism first drives the connecting rod to move forward toward the channel and toward one end of the mesh threading machine. During the forward movement, the lever moves the node on the spring, allowing the spring to move forward. When the spring moves forward to a certain distance, the connecting rod drops, then retreats, reaches the rear of the previous spring, and then repeats, thus completing the conveying of the spring. During the conveying process, the spring node is moved by the lever, so the position of the spring node remains unchanged during the forward movement of the spring, thus eliminating the need for the subsequent mesh threading machine to reposition the position of the spring node, greatly simplifying the structure, and also improving the processing efficiency.

[0014] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments:
[0015] See also Figures 1 to 2 The spring conveying mechanism comprises a bracket 1, on which a channel 2 formed by two baffles 21 parallel to each other is arranged, and the channel is arranged obliquely upward.
[0016] One end of the channel 2 is connected to the outlet of a spring production device (not shown in the figure), and the other end of the channel is connected to the feeding port of a mesh threading machine (not shown in the figure).
[0017] The two ends of the spring 3 are clamped on the baffle 21. The device also includes a toggle mechanism 4 for toggle the spring 3, the toggle mechanism 4 includes two parallel connecting rods 41, the two connecting rods 41 are fixed together by two connecting columns 42, a plurality of toggle rods 42 are arranged on the connecting rod 41, and the top of the toggle rod 42 has an inclined surface 421 inclined upward along the channel 2. The toggle rod 42 cooperates with the node 31 on the spring 3, and the number of the toggle rods 42 corresponds to the number of the springs 3 in the channel, and also includes a driving mechanism 5 for driving the toggle mechanism 4 to move forward along the channel 2 and driving the toggle mechanism 4 to move up and down.
[0018] When in use, the driving mechanism first drives the connecting rod to move forward toward the channel and toward one end of the threading machine. During the forward movement, the lever moves the node on the spring, allowing the spring to move forward. When the spring moves forward to a certain distance, the connecting rod drops and then retreats to the rear of the previous spring, and then repeats, thus completing the spring conveying. During the conveying process, the spring node is moved by the lever, so the position of the spring node remains unchanged during the forward movement of the spring, which saves the subsequent threading machine from repositioning the spring node position, greatly simplifies the structure, and also improves the processing efficiency.
[0019] See also Figure 3The driving mechanism 5 includes a rotating shaft 51, a first rod 52 and a convex plate 57, one end of the first rod 52 is connected to the toggle mechanism 4, the other end of the first rod 52 is connected to the slider 53, the slider 53 is provided with a slide groove, the slide groove is slidably connected to the second rod 54, the second rod 54 is fixed on the bracket 1, the second rod 54 and the channel 2 are arranged parallel to each other, the rotating shaft 51 is hinged to one end of the rotating rod 55, the other end of the rotating rod 55 is hinged to one end of the third rod 56, the other end of the third rod 56 is hinged to the slider 53, the convex plate 57 is slidably connected to the fourth rod 58, the fourth rod 58 is arranged parallel to the channel 2, the bottom of the first rod 52 abuts against the convex plate 57, and the other end of the rotating rod 55 is connected to the convex plate 57 through the fifth rod 59.
[0020] This driving mechanism includes two sets of hinged four-bar mechanisms, one set is a first hinged four-bar mechanism consisting of a rotating rod 55, a third rod 56, a slider 53 and a second rod 54, and the other set is a second hinged four-bar mechanism consisting of a rotating rod 55, a fifth rod 59, a convex plate 57 and a fourth rod 58. The reciprocation of the slider 53 driven by the first hinged four-bar mechanism is one angle ahead of the reciprocation of the convex plate 57 driven by the second hinged four-bar mechanism.
[0021] When in use, the rotating shaft drives the rotating rod to rotate. During the advancement stroke, the rotating rod drives the third rod to swing, and the third rod drives the slider to slide upward on the second rod. The slider moves synchronously with the first rod and the connecting rod, and the lever on the connecting rod drives the spring to move along the channel. During the advancement stroke, the first rod gradually moves along the inclined surface on the convex plate to the high point of the convex plate, ensuring that the toggle device is in a high position and can contact the node on the spring. After being pushed to the position, the slider now retreats, but the convex plate retreats later than the slider, so the first rod will slide from the convex plate along the inclined surface on the convex plate from the highest point to prevent the lever from toggling the rear spring during the retreat process. During the retreat stroke, the rotating rod drives the third rod to swing, and the third rod drives the slider to slide downward on the second rod, and the lever on the connecting rod retreats to the next spring. At this time, the convex plate is still in the retreat stroke, and the first rod gradually moves along the inclined surface to the highest point of the baffle, and the lever can contact the spring again, and then it is the advancement stroke again, and so on.
