[0033] 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.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0035] Please see Figure 1-5 As shown, this utility model is a screw cap tightening force adjuster, comprising:

[0036] A base plate 100, a rotating ring 110 is rotatably connected to one side surface of the base plate 100, and a rotating column 120 is rotatably connected inside the rotating ring 110;

[0037] The counting mechanism includes a short plate 210, a first square hole 220, a first inclined column 230, a guide rod 240, a first spring 250, a baffle 260, and a pressure sensor 270.

[0038] A short plate 210 is fixedly connected to the side wall of the rotating column 120. A first square hole 220 is opened inside the side wall of the rotating ring 110. A first inclined column 230 is slidably connected inside the first square hole 220. A guide rod 240 is fixedly connected to the bottom of the first inclined column 230. A baffle 260 is fixedly connected to the middle of the first square hole 220. The two ends of the first spring 250 are respectively fixedly connected to the bottom of the first inclined column 230 and the top of the first spring 250. A pressure sensor 270 is fixedly connected to the bottom of the pressure sensor 270. The number of sensing cycles of the pressure sensor 270 is set according to the number of thread turns at the bottle mouth of different bottles. When the rotating column 120 rotates, it drives the short plate 210 to rotate. After each rotation, the short plate 210 contacts the inclined surface of the first inclined column 230 and is pressed into the first square hole 220 through the inclined surface of the first inclined column 230, thus compressing the first spring 250. The first inclined column 230 drives the guide rod 240 to slide downward. When the first inclined column 230 is completely slid into the first square hole 220, the bottom of the guide rod 240 contacts the pressure sensor 270. At this time, the pressure sensor 270 senses once. The number of rotations of the rotating column 120 is counted by the number of senses. The model of the pressure sensor 270 can be PSK1.

[0039] The blocking assembly includes a second square hole 281, a second inclined column 282, a telescopic column 283, and a second spring 284.

[0040] The second square hole 281 is opened inside the side wall of the rotating ring 110. The second inclined column 282 is slidably connected inside the second square hole 281. The telescopic column 283 and the second spring 284 are respectively fixedly connected to the bottom of the second square hole 281 and the bottom of the second inclined column 282. The second spring 284 rebounds and drives the second inclined column 282 to slide out of the second square hole 281, and then pulls up the telescopic column 283. After the second inclined column 282 slides out of the second square hole 281, it blocks the short plate 210 to prevent the rotating column 120 from rotating more than the predetermined number of turns.

[0041] The blocking assembly also includes a gate 285, a second motor 286, a gear 287, a rack 288, and an inner groove 289;

[0042] The inner groove 289 is opened on the top side wall of the second square hole 281. The stop gate 285 is slidably connected in the inner groove 289. The second motor 286 is fixedly connected to the bottom side wall of the stop gate 285. The gear 287 is fixedly connected to the power output end of the second motor 286. The rack 288 is fixedly connected to the bottom of the inner groove 289. The gear 287 and the rack 288 mesh. When the second motor 286 is started, the second motor 286 drives the gear 287 to rotate, so that the gear 287 rolls on the rack 288, thereby driving the stop gate 285 to slide open and close.

[0043] A first motor 130 is fixedly connected to the other side surface of the base plate 100. The power output end of the first motor 130 is fixedly connected to the rotating column 120. A fixed circular plate 140 is fixedly connected to the end of the rotating column 120. When the number of sensing times reaches a predetermined number, the pressure sensor 270 controls the first motor 130 to stop rotating through the signal line and controls the second motor 286 to start in time through the signal line to avoid the bottle cap being rotated too tightly or too loosely, which would affect its use.

[0044] A triangular plate 291 is fixedly connected to the side wall of the rotating ring 110. A graduation scale 292 is fixedly set on one side surface of the base plate 100. Threaded holes 293 are opened on the surface of the base plate 100. There are multiple threaded holes 293. A screw 294 passes through the triangular plate 291. The screw 294 is threaded into the corresponding threaded hole 293. When the number of rotations to be set is not an integer, the rotating ring 110 can be rotated to a predetermined decimal number of rotations. Then, the screw 294 is passed through the triangular plate 291 and screwed into the corresponding threaded hole 293 to fix the rotating ring 110. Then, the number of times the pressure sensor 270 senses is set to an integer. This allows for more precise control of the tightening degree.

[0045] Working principle: The number of sensing cycles of the pressure sensor 270 is set according to the number of thread turns at the bottle mouth of different bottles. When the rotating column 120 rotates, it drives the short plate 210 to rotate. Each rotation contacts the inclined surface of the first inclined column 230 and squeezes the first inclined column 230 into the first square hole 220, compressing the first spring 250. The first inclined column 230 drives the guide rod 240 to slide downward. When the first inclined column 230 has completely slid into the first square hole 220, the bottom of the guide rod 240 contacts the pressure sensor 270. At this time, the pressure sensor 270 senses once. The number of sensing cycles counts the number of rotations of the rotating column 120. When the number of sensing cycles reaches a predetermined number, the pressure sensor 270 controls the first motor 130 to stop rotating via a signal line and controls the second motor 286 to start in time via a signal line. The second motor 286 drives the gear 287 to rotate, causing the gear 287 to roll on the rack 288, thereby causing the stop door 285 to slide open. This causes the second spring 284 to rebound, causing the second inclined column 282 to slide out of the second square hole 281 and then pull up the telescopic column 283. After the second inclined column 282 slides out of the second square hole 281, it blocks the short plate 210, preventing the rotating column 120 from rotating more than the predetermined number of turns due to inertia. When the number of rotations to be set is not an integer, the rotating ring 110 can be rotated to the predetermined decimal number of turns first. Then, the screw 294 is passed through the triangular plate 291 and screwed into the corresponding threaded hole 293 to fix the rotating ring 110. Then, the pressure sensor 270 is set to sense an integer number of times. This prevents the bottle cap from being rotated too tightly or too loosely, which would affect its use. The tightness of the bottle cap can be flexibly adjusted by counting the number of rotations.

[0048] The surface of the fixed base plate 310 is slidably connected to the arc-shaped clamping plate 320. There are multiple arc-shaped clamping plates 320. The rotating plate 330 is rotatably connected to the bottom of the fixed base plate 310. The bottom of the arc-shaped clamping plate 320 is slidably connected to the surface of the rotating plate 330. The cross plate 340 is fixedly connected to the bottom of the fixed base plate 310. The third motor 350 is fixedly connected to the middle of the cross plate 340. The rotating plate 330 is fixedly connected to the power output end of the third motor 350. When the third motor 350 is started, the third motor 350 drives the rotating plate 330 to rotate. The rotating plate 330 drives the bottom of the arc-shaped clamping plate 320 to slide on the rotating plate 330 and slide towards the center on the surface of the fixed base plate 310, so that the fixed base plate 310 clamps the bottle cap.

[0049] The surface of the fixed base plate 310 is provided with a sliding groove 311, and there are multiple sliding grooves 311. The bottom of the arc-shaped clamping plate 320 is fixedly connected to a sliding column 321, which is slidably connected in the sliding groove 311. The bottom of the fixed base plate 310 is fixedly connected to a fixed column 312, which is fixedly connected to the surface of the fixed circular plate 140. The sliding column 321 at the bottom of the arc-shaped clamping plate 320 slides in the sliding groove 311, so that the arc-shaped clamping plate 320 slides towards the center of the fixed base plate 310 to clamp the bottle cap.

[0050] A protruding post 322 is fixedly connected to the bottom surface of the sliding post 321. An arc-shaped groove 331 is opened on the surface of the rotating plate 330. The protruding post 322 is slidably connected in the arc-shaped groove 331. The rotation of the rotating plate 330 drives the protruding post 322 to slide in the arc-shaped groove 331, so that the protruding post 322 drives the sliding post 321 to slide.

[0051] Working principle: Start the third motor 350, which drives the rotating plate 330 to rotate. The rotation of the rotating plate 330 causes the protruding post 322 to slide in the arc groove 331, so that the protruding post 322 drives the sliding post 321 to slide in the sliding groove 311. This causes the arc clamping plate 320 to slide towards the center of the fixed base plate 310 to clamp the bottle cap. The first motor 130 drives the rotating post 120 to rotate, which drives the fixed circular plate 140 to rotate. The fixed circular plate 140 drives the fixing mechanism 300 to rotate and tighten the bottle cap. It can tighten bottle caps of different sizes.
