[0027] like Figures 5 to 7As shown, the water outlet cutting mechanism 2 includes a fixed plate 202, a guide column 203, a vertical cylinder 201 and a movable plate 204. The fixed plate 202 is located above the water outlet 103. The four corners of the fixed plate 202 are fixedly connected to the bottom plate 1 through the guide columns 203. The four guide columns 203 are respectively located on the outsides of the two slide rails 101. The cylinder barrel of the vertical cylinder 201 is fixed to the top of the fixed plate 202. The piston rod of the vertical cylinder 201 is connected to the top of the movable plate 204. The movable plate 204 is movably sleeved on the guide column 203.

[0028] In this embodiment, the water cutting mechanism 2 further includes a pressure plate 205, a guide rod 209, a guide sleeve 208, and a buffer spring 210. A passage is provided in the middle of the pressure plate 205 for the cutter 206 to pass through. Guide sleeves 208 are respectively provided at the four corners of the pressure plate 205. The guide rod 209 is movably inserted into the guide sleeve 208. The buffer spring 210 is sleeved on the guide rod 209. One end of the guide rod 209 is connected to the bottom surface of the movable plate 204, and the other end passes through the movable plate 204 from the guide sleeve 208 and is provided with a limiting structure 211.

After cutting off the water outlet 5, the movable plate 204 and the cutter 206 move upward. Under the action of the buffer spring 210, the pressure plate 205 will not move together, so that the blade 215 will not drive the product 4 to fall to the ground.

[0029] The cutter 206 includes a cutter seat 214, a holding piece 218 and a plurality of blades 215. One end of the cutter seat 214 is fixedly connected to the movable plate 204. The holding piece 218 is connected to the middle of the other end of the cutter seat 214 through a spring 219. The blades 215 are connected to the other end of the cutter seat 214 and are arranged around the holding piece 218. The blades 215 are fixed to the cutter seat 214 with screws. The number of blades 215 is determined according to the number of products 4. The two cutter seats 214 are fixed to the bottom surface of the fixed plate 202 with screws and move up and down with the fixed plate 202. A through hole is opened in the middle of the pressing plate 205. When the cutter 206 moves down, it passes through the through hole to cut off the water outlet 5. When cutting the water outlet, the holding piece 218 presses against the middle of the water outlet, and the cutter 206 cuts the water outlet from the pipe fitting from the edge of the water outlet.

[0030] Each group of clamping components 207 includes a clamping cylinder 216 and a nozzle clamp. The piston rod of the clamping cylinder 216 is connected to the nozzle clamp. The two clamping cylinders 216 are relatively arranged on both sides of the straight line where the two groups of cutters 206 are located and there is a gap. The control system is independently controlled and connected to the clamping cylinders 216. The design of the two groups of cutters 206 can cut multiple nozzles of the whole mold product 4 at the same time. There is a gap between the two groups of cutters 206. The two clamping components 207 are located on opposite sides of this gap. When the cutter 206 reaches the nozzle cutting position, the clamping cylinder 216 pushes the nozzle clamp to clamp the nozzle first. After cutting the nozzle, the fixed plate 202 moves upward, and the nozzle clamp moves upward with the nozzle; when the slide plate 102 returns to the starting position, the two clamping cylinders 216 retract, and the nozzle clamp is released, and the nozzle falls into the collection box from the nozzle blanking port 103.

[0031] like Figure 8 As shown, the stripping mechanism 3 includes a slide bar 301 arranged in parallel on one side of the slide rail 101, a linear slider 302 slidably connected to the slide bar 301, a railing 303 fixedly connected to the side of the linear slider 302, and a stripping cylinder (not shown in the figure) driving the linear slider 302 to slide back and forth on the slide bar 301, the piston rod of the stripping cylinder is fixedly connected to the linear slider 302, both ends of the slide bar 301 are fixed to the base plate 1 by support frames 304, the railing 303 is perpendicular to the slide rail 101 and is located above the slide rail 101, and the sliding stroke of the railing 303 is from directly above the water outlet 103 to directly above the product outlet 104. The guide rod in the stripping mechanism 3 ensures that the linear slider 302 will not tilt or deviate. The railing 303 is installed on the side of the fixed block and fixed with screws. When the product cuts off the water outlet and the pressure plate 205 rises, the linear slider 302 moves forward under the push of external force, and the railing 303 sweeps all the products 4 into the product drop port 104, and then loads them into the product collection box.

[0032] The bottom plate 1 is also provided with buffer positioning devices 112 at both ends of the slide rails 101 for preventing the slide plate 102 from overtravel; the bottom plate 1 is also provided with linear guide rods 109 parallel to the slide rails 101 on the outside of the two slide rails 101, and the slide plate 102 is also provided with a sliding block 110 on the side close to the linear guide rod 109, and the sliding block 110 is slidably connected to the linear guide rod 109. The bottom plate 1 in this embodiment is provided with a guide opening 111. In order to save space, the linear guide rod 109 is provided on one side of the bottom surface of the bottom plate 1. The sliding block 110 passes through the guide opening 111 and is connected to the slide plate 102. When the sliding block 110 moves along the linear guide rod 109, it also moves in the guide opening 111; the two buffer positioning devices 112 at both ends are respectively the starting position and the ending position of the slide plate 102 for reciprocating movement, to prevent the slide plate 102 from being damaged, and the whole mold product 4 is placed at the starting position, and the water cut is made at the ending position.

[0033] The entire working principle of this embodiment is as follows: when the slide plate 102 is located at the initial position, the whole mold product is placed on the slide plate 102, and then the control system controls the horizontal cylinder to push the slide plate 102 to move to the end position. When it reaches the end position, the slide plate 102 is located directly above the nozzle blanking port 103; the vertical cylinder 201 drives the movable plate 204 to move down along the guide column 203. After moving down to the right position, the clamping cylinder 216 is actuated to drive the nozzle clamp to clamp the nozzle, and then the movable plate 204 continues to move down to drive the cutter 206 to cut off the nozzle. After the nozzle is cut off, the vertical cylinder 201 drives the movable plate 204 to rise, and the pressure plate 205 also rises and lifts the nozzle at the same time; then the stripping cylinder in the stripping mechanism 3 is actuated The linear slider 302 moves along the slide bar 301, and the railing 303 on the slide bar 301 sweeps over the slide plate 102, and the product 4 is sent to the product drop port 104 and loaded into the product collection box; then the slide plate 102 returns to the initial position, the clamping assembly 207 releases the nozzle clamp, and the nozzle falls from the drop port into the nozzle collection box, and this cycle repeats; this embodiment realizes the automation of the entire nozzle cutting process from product feeding to nozzle cutting, and then to the dropping of product and nozzle waste after nozzle cutting, with a compact processing rhythm, so as to achieve the purpose of collecting products and nozzles separately, greatly improving production efficiency, saving manpower, and reducing labor intensity; and the entire equipment structure is simpler and the manufacturing cost is lower.
