Detailed description of the specific implementation

[0026] Now, the present utility model will be further described in detail with reference to the drawings.

[0027] Please refer to Figures 1-3 As shown, in this embodiment, a hose cutting device is provided, including a workbench 1, on which a clamping and pulling assembly, a bracket, and two first electric push rods 3 are arranged. The bracket is located between the clamping and pulling assembly and the first electric push rod 3;

[0028] The output shaft of the first electric push rod 3 is fixedly connected to a U-shaped frame, and a rotating cylinder 305 is rotatably fitted on the U-shaped frame;

[0029] A second electric push rod 5 is arranged on the bracket. The output shaft of the second electric push rod 5 is fixedly connected to a pressing plate 6. A cutting knife 7 is installed below the pressing plate 6. Two elastic pressing assemblies are arranged on the pressing plate 6. Both the bracket and the cutting knife 7 are located between the two elastic pressing assemblies. A ramp groove 101 corresponding to the clamping and pulling assembly and a cutting groove 102 corresponding to the cutting knife 7 are provided on the workbench 1. The ramp groove 101 penetrates one side of the workbench 1;

[0030] The bracket includes two support plates 4 installed on the upper surface of the workbench 1. A load-bearing plate 401 is installed on the upper sides of the two support plates 4. The second electric push rod 5 is installed on the upper surface of the load-bearing plate 401. The output shaft of the second electric push rod 5 vertically penetrates the load-bearing plate 401. The pressing plate 6, the cutting knife 7, and the elastic pressing assembly are all located below the load-bearing plate 401 and between the two support plates 4.

[0031] An application of one aspect of this embodiment is as follows: During use, pass the hose to be cut into sections through between the two rotating cylinders 305, and then place it below the elastic pressing assembly. At this time, start the first electric push rod 3 to extend and push the rotating cylinder 305 to displace, so that both rotating cylinders 305 are in contact with the hose. Then control the clamping and pulling assembly to extend to clamp the end of the hose. After being clamped and fixed, the clamping and pulling assembly contracts to pull the hose to displace. The displacement of the hose drives the two rotating cylinders 305 to rotate. When the hose is pulled to the required length, the first electric push rod 3 slightly extends, so that the two rotating cylinders 305 squeeze and clamp the hose. At this time, the second electric push rod 5 extends to push the pressing plate 6 downward. The downward movement of the pressing plate 6 pushes the elastic pressing assembly and the cutting knife 7 downward. During this process, the elastic pressing assembly first contacts the hose. The continuous downward movement of the pressing plate 6 causes the elastic pressing assembly to press the hose on the workbench 1 under the action of elastic force. Then the pressing plate 6 moves downward to cut the hose with the cutting knife 7. After the cutting is completed, the second electric push rod 5 drives the pressing plate 6 to reset. At this time, the clamping and pulling assembly contracts to pull the cut part of the hose to the ramp groove 101 and release it, so that it slides down from one side of the workbench 1 along the ramp groove 101, thereby completing a single hose cutting section. Similarly, referring to the above operations, the hose can be continuously cut into sections.

[0032] The U-shaped frame of this embodiment includes a vertical plate 301 fixedly connected to the output shaft of the first electric push rod 3. A horizontal plate 302 is installed on the upper side of the vertical plate 301. A central column 303 is installed on the lower side of the horizontal plate 302. Two bearings 304 are installed on the peripheral side of the central column 303. The two bearings 304 are respectively close to the upper and lower ends of the central column 303. The rotating cylinder 305 is installed on the peripheral sides of the two bearings 304. The rotating cylinder 305 is located between the two vertical plates 301. The friction between the rotating cylinder 305 and the central column 303 during rotation is reduced through the bearings 304.

[0033] The elastic pressing assembly of this embodiment includes two sliding rods 8 vertically penetrating the pressing plate 6. A stopper 802 is provided at the upper end of the sliding rod 8. A pressing strip 801 is installed at the lower ends of the two sliding rods 8. A spring 9 sleeved on the peripheral side of the sliding rod 8 is provided between the pressing strip 801 and the pressing plate 6. The probability of the sliding rod 8 detaching from the pressing plate 6 is reduced through the stopper 802, and at the same time, it is convenient for the pressing plate 6 to drive the elastic pressing assembly to move upward and reset when moving upward.

[0034] The clamping and pulling assembly of this embodiment includes a third electric push rod 10 installed on the upper surface of the workbench 1. A ramp groove 101 is located between the third electric push rod 10 and the adjacent pressure strip 801. A plate body 11 is fixedly connected to the output end of the third electric push rod 10. On the side of the plate body 11 away from the third electric push rod 10, there is a first sliding groove 1101, and two clamping plates 13 are slidably engaged therewith. A motor 12 is installed on one side of the plate body 11. The output shaft of the motor 12 is fixedly connected to a bidirectional lead screw 1201 that is rotatably engaged in the first sliding groove 1101. On one side of the clamping plate 13, there is a screw barrel 1301 that is threadedly engaged with the circumferential side of the bidirectional lead screw 1201. The screw barrel 1301 is slidably engaged in the first sliding groove 1101. By the operation of the motor 12 to drive the bidirectional lead screw 1201 to rotate, the two screw barrels 1301 are driven to approach or move away from each other, so as to realize the clamping and release of the end of the hose by the two clamping plates 13.

[0035] In this embodiment, two second sliding grooves 1102 are transversely provided on the plate body 11. The second sliding grooves 1102 penetrate the plate body 11. The first sliding groove 1101 is located between the two second sliding grooves 1102. Guide rods 1103 are installed between the two inner walls on both sides of the second sliding groove 1102. On one side of the clamping plate 13, there is a sleeve 1302 sleeved on the guide rod 1103. The sleeve 1302 is slidably engaged in the second sliding groove 1102. Through the cooperation of the guide rod 1103 and the sleeve 1302, the stability of the clamping plate 13 during sliding is improved, and the probability of the bidirectional lead screw 1201 rotating to drive the clamping plate 13 and the screw barrel 1301 to shake is reduced.

[0036] Four support legs 2 are installed under the workbench 1 of this embodiment. A base 201 is installed at the lower end of the support leg 2. An anti-slip pad 202 is installed at the lower end of the base 201.
