Technical Field
[0001] This utility model relates to the field of blood pressure monitor armband production technology, specifically a blood pressure monitor armband feeding and conveying device. Background Technology
[0002] A blood pressure monitor is a medical instrument used to detect human blood pressure. It mainly measures blood pressure by analyzing the sound or vibration changes when blood flow is restored after the blood pressure cuff is inflated and blocked. There are two types: mercury cuff and electronic cuff. The electronic cuff is more commonly used in households due to its portability. During the production process, a transmission device is needed to feed the blood pressure cuff.
[0003] According to Chinese Utility Model Patent Application No. CN202220365982.4, a material guiding device for cutting blood pressure monitor cuffs is proposed. The utility model describes that "this utility model has a limiting structure on the material guiding roller. By pulling the limiting rod, the limiting block connected to the bottom of the limiting rod moves away from the limiting hole on the material guiding roller until the limiting block disengages from the limiting hole. The limiting ring is rotated to make the position of the limiting block misalign with the position of the limiting hole. The limiting ring is slid to a suitable position, and the limiting ring is rotated to make the position of the limiting block correspond to the position of the limiting hole. Under the action of the spring, the limiting block slides along the limiting hole. At this time, the limiting block slides into the limiting hole, completing the adjustment of the upper limiting ring of the material guiding roller, and avoiding material deviation due to different sizes during the material guiding process, which would affect the subsequent cutting quality."
[0004] The feeding device for cutting blood pressure monitor cuffs has two limiting rings installed in the limiting holes of the feeding roller via a snap-fit assembly. The multiple limiting holes are evenly and equidistantly distributed, but there are gaps between adjacent limiting holes. This causes the adjustment process of the two limiting rings to be discontinuous, resulting in gaps between the opposite side of the two limiting rings and the two sides of the blood pressure monitor cuff. During the transmission process, the blood pressure monitor cuff is prone to deviation, affecting the transmission effect. Therefore, an improvement is needed. Thus, a blood pressure monitor cuff feeding and transmission device is proposed to solve the above problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a blood pressure monitor cuff feeding and conveying device, which has advantages such as easy continuous adjustment. It solves the problem that gaps exist between adjacent limiting holes, causing discontinuous adjustment of the two limiting rings. This results in gaps between the opposite side of the two limiting rings and the two sides of the blood pressure monitor cuff, making the blood pressure monitor cuff prone to shifting during transmission and affecting the transmission effect.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a blood pressure monitor cuff feeding and conveying device, including a base, a conveying mechanism connected to the top of the base, a horizontal plate fixedly installed inside the conveying mechanism, an adjusting mechanism connected to the top of the horizontal plate, and a limiting mechanism for limiting the conveying mechanism connected to the adjusting mechanism.
[0007] The adjustment mechanism includes a chamber body, which is fixedly connected to the top of the horizontal plate. A dual-axis motor is fixedly installed on the inner bottom wall of the chamber body. Threaded rods are fixedly installed on both output ends of the dual-axis motor. The sides of the two threaded rods away from the output ends of the dual-axis motor are rotatably connected to the inner side wall of the chamber body. The threads of the two threaded rods are in opposite directions. Threaded sleeves are threadedly installed on the outside of the two threaded rods. Moving rods that penetrate and extend above the chamber body are fixedly installed on the side walls of the two threaded sleeves. The limiting mechanism is connected to the moving rods.
[0008] Furthermore, the transmission mechanism includes two side plates, both of which are fixedly connected to the top of the base. A motor is fixedly installed on the side wall of one of the side plates. The output end of the motor passes through the side plate and is fixedly installed with a guide roller. The side of the guide roller away from the motor output end is rotatably connected to the side wall of the other side plate.
[0009] Furthermore, there are two horizontal plates, both of which are fixedly connected to the opposite side of the two side plates. The compartment body is fixedly connected to the top of the lower horizontal plate. The side wall of the moving rod passes through and extends to the top of the upper horizontal plate. The top of the upper horizontal plate is provided with a first moving hole that matches the moving rod.
[0010] Furthermore, the limiting mechanism includes a connecting block, which is inserted into the side wall of the moving rod. The side wall of the moving rod is threaded with a bolt that is threadedly connected to the connecting block. A connecting rod is fixedly installed on the side wall of the connecting block. A limiting plate is fixedly installed on the side wall of the connecting rod. The limiting plate has a groove inside that matches the guide roller.
[0011] Furthermore, the cross-section of the movable rod is L-shaped, and there are four movable rods in total. Two movable rods are grouped together, and two movable rods are symmetrically fixedly connected to both sides of the threaded sleeve. The side wall of the chamber body is provided with a second movable hole that matches the movable rod.
[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0013] This blood pressure monitor cuff feeding and conveying device consists of a base, a conveying mechanism, a horizontal plate, an adjusting mechanism, and a limiting mechanism. The operator first places the blood pressure monitor cuff material at the top center of the conveying mechanism. Then, the limiting mechanism is installed on the adjusting mechanism, which moves the limiting mechanism to a designated position. Finally, the conveying mechanism transports the blood pressure monitor cuff. The adjusting mechanism can continuously adjust the position of the limiting mechanism, which limits the cuff on both sides, reducing the gap between the limiting mechanism and the cuff. This prevents the cuff from shifting during transport, improving the conveying efficiency. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0020] Please see Figure 1-4 The blood pressure monitor arm cuff feeding and conveying device in this embodiment includes a base 1, a conveying mechanism 2 connected to the top of the base 1, a horizontal plate 3 fixedly installed inside the conveying mechanism 2, an adjusting mechanism 4 connected to the top of the horizontal plate 3, and a limiting mechanism 5 for limiting the conveying mechanism 2 connected to the adjusting mechanism 4.
[0021] Specifically, the staff first places the blood pressure monitor cuff material at the top center of the transmission mechanism 2, then installs the limiting mechanism 5 on the adjusting mechanism 4, and then uses the adjusting mechanism 4 to move the limiting mechanism 5 to the designated position. Finally, the transmission mechanism 2 is used to transmit the blood pressure monitor cuff. The adjusting mechanism 4 can continuously adjust the position of the limiting mechanism 5. The limiting mechanism 5 limits both sides of the blood pressure monitor cuff, reducing the gap between the limiting mechanism 5 and the blood pressure monitor cuff. During the transmission process, the blood pressure monitor cuff is less likely to deviate, thus improving the transmission effect.
[0022] In this embodiment, the transmission mechanism 2 includes two side plates 21, both of which have rectangular bottoms and arc-shaped tops. There are two horizontal plates 3, which are fixedly connected to opposite sides of the two side plates 21. Both side plates 21 are fixedly connected to the top of the base 1. A motor 22 is fixedly installed on the side wall of one of the side plates 21. The output end of the motor 22 passes through the side plate 21 and is fixedly installed with a guide roller 23. The side of the guide roller 23 away from the output end of the motor 22 is rotatably connected to the side wall of the other side plate 21 through a first bearing.
[0023] Specifically, by turning on the motor 22, the motor 22 drives the guide roller 23 to rotate, and the guide roller 23 drives the blood pressure monitor cuff material to be transported, thereby feeding the blood pressure monitor cuff material.
[0024] In this embodiment, the adjustment mechanism 4 includes a chamber 41, which is fixedly connected to the top center of the lower horizontal plate 3. A dual-axis motor 42 is fixedly installed at the center of the inner bottom wall of the chamber 41. Threaded rods 43 are fixedly installed at both output ends of the dual-axis motor 42. The side of each threaded rod 43 away from the output end of the dual-axis motor 42 is rotatably connected to the inner side wall of the chamber 41 through a second bearing. The threads of the two threaded rods 43 are opposite in direction and equal in length. Threaded sleeves 44 are symmetrically threaded on the outside of each threaded rod 43. Two movable rods 45, penetrating the chamber 41 and extending to the top of the upper horizontal plate 3, are symmetrically fixedly installed on the side walls of each of the two threaded sleeves 44. The cross-section of each of the four movable rods 45 is L-shaped. A first movable hole matching the movable rods 45 is opened at the top of the upper horizontal plate 3, and a second movable hole matching the movable rods 45 is opened on the side wall of the chamber 41.
[0025] Specifically, by activating the dual-axis motor 42, the dual-axis motor 42 drives the two threaded rods 43 to rotate, and the two threaded rods 43 drive the two threaded sleeves 44 and the four moving rods 45 to move relative to each other or in opposite directions.
[0026] In this embodiment, the limiting mechanism 5 includes four connecting blocks 51, which are respectively inserted into the side walls of four moving rods 45. Each of the four moving rods 45 has a bolt 52 threadedly connected to the connecting block 51 on its side wall. The interior of each of the four moving rods 45 and the four moving rods 45 are provided with threaded grooves that are threadedly connected to the bolts 52. Each of the four connecting blocks 51 has a connecting rod 53 fixedly installed on its side wall. Each of the four connecting rods 53 has a limiting plate 54 fixedly installed on its side wall. Each of the four limiting plates 54 has a groove that matches the guide roller 23. The four grooves form two limiting grooves. The distance between the two limiting grooves and the guide roller 23 is less than 2mm.
[0027] Specifically, first, four limiting plates 54 are placed on the outside of the guide roller 23. Then, the four limiting plates 54 are moved horizontally so that the four connecting blocks 51 are inserted into the side walls of the four moving rods 45. Then, four bolts 52 are screwed into the inside of the four moving rods 45 and the four connecting blocks 51 for fixation, so that the four limiting plates 54 limit the two sides of the guide roller 23. The gap between the four limiting plates 54 and the two sides of the guide roller 23 is less than 2mm.
[0028] The working principle of the above embodiments is as follows:
[0029] The operator first places the blood pressure monitor cuff material at the top center of the guide roller 23. Then, two limiting plates 54 are placed on the outside of the guide roller 23 and moved horizontally so that two connecting blocks 51 are inserted into the side walls of two moving rods 45. Next, two bolts 52 are screwed into the two moving rods 45 and the two connecting blocks 51 for fixation. Then, the dual-axis motor 42 is turned on, which drives two threaded rods 43 to rotate. The two threaded rods 43 drive two threaded sleeves 44, four moving rods 45, four connecting blocks 51, four bolts 52, four connecting rods 53 and four limiting plates 54 to move relative to the designated position. Finally, the motor 22 is turned on, which drives the guide roller 23 to rotate. The guide roller 23 carries the blood pressure monitor cuff material for transmission. The four limiting plates 54 limit the guide roller 23. By continuously adjusting the position of the four limiting plates 54, the gap between the four limiting plates 54 and the blood pressure monitor cuff is reduced, making it less likely for the blood pressure monitor cuff to shift during transmission and improving the transmission efficiency.
