[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0020] The trimming and forming device of the present invention belongs to a part of the intelligent manufacturing equipment industry. It is a type of equipment used for grinding the rotating surface of a workpiece, and is used for trimming the port position annular surface and the inner wall of the side hole of the plastic trash can.

[0021] Example 1: Refer to the appendix of the instruction manual. Figures 1-3 , Figure 7 and Figure 11 This invention provides a plastic trash can trimming and forming device. The frame 1 consists of a concave ring platform and a foot column fixed to the bottom of the concave ring platform. The port trimming mechanism 3 includes a ring plate 31 movably sleeved inside the concave ring platform, two symmetrically arranged propulsion components 32 fixed to the top of the ring plate 31, a pressure block 34 fixed on the propulsion components 32 for feeding the trimming component 23, and trimming component 23 installed on each propulsion component 32. The thickness of the ring plate 31 is greater than the depth of the column cavity on the concave ring platform. The port trimming mechanism 3 is installed on the top of the frame 1. Furthermore, a rotary drive mechanism 4 is provided between the frame 1 and the port trimming mechanism 3 for rotating and polishing the trash can port by actuating the port trimming mechanism 3.

[0022] It should be noted that during the edge trimming process of the molded plastic trash can (hereinafter referred to as the target trash can) using this invention, the edges are trimmed as follows: Figure 12 The plastic trash can shown is mounted on the cylindrical cavity axis of the concave ring platform by a clamping fixture. Then, the trimming component 33 is pushed to the trimming area at the port of the target trash can by the pushing component 32 and trimmed against the surface to be trimmed at the port of the target trash can. During this process, the rotary drive mechanism 4 is used to drive the trimming component 33 to rotate along the circumferential side of the target trash can to complete the trimming of the rotating surface at the port of the target trash can.

[0023] Furthermore, such as Figure 7-Figure 8As shown, the propulsion component 32 includes a U-shaped frame 321 fixed to the top of the ring disk 31 and a cylinder 322 fixed to the middle of the outer side of the U-shaped frame 321. Side guide blocks 323 are fixedly provided on both sides of the inner cavity of the U-shaped frame 321, and the two side guide blocks 323 cooperate with the U-shaped frame 321 to form an I-shaped slide. The I-shaped frame 324 is slidably connected to the inside of the I-shaped slide inside the U-shaped frame 321. The telescopic end of the cylinder 322 is fixedly connected to the I-shaped frame 324. The I-shaped slide can be used to enhance the stability of the I-shaped frame 324 when sliding inside the U-shaped frame 321. A connecting rod 325 is fixedly connected to one side of the top of the I-shaped frame 324, and a pressure block 34 is fixedly sleeved on the outside of the connecting rod 325.

[0024] It should be noted that during the edge trimming process at the port of the target trash can, the cylinder 322 is used to push the I-beam frame 324 along the I-beam structure slide rail inside the U-shaped frame 321 toward the target trash can, so that the edge trimming component 33 moves to the processing area at the port.

[0025] Furthermore, such as Figures 7-10 As shown, the trimming assembly 2 33 includes a grinding block 331 fixedly connected to the end of the connecting rod 325. The side of the grinding block 331 facing the target trash can is curved to better fit the surface to be trimmed at the port of the target trash can, improving trimming quality. Four connecting rods 325 are connected to the grinding block 331, positioned at the four corners of the grinding block 331, enhancing the stability of the trimming assembly 2 33 installation. Straight guide grooves 332 are provided at the top center and bottom center of the grinding block 331, and both straight guide grooves 332 allow for sliding installation. The device is equipped with slides 333, and each slide 333 has a pressure seat 3311 integrally formed on one side. The pressure seat 3311 and the slide 333 are connected by a shaft 334 at the central axis position. A grinding roller 335 is fixedly sleeved on the outer side of one end of each shaft 334. The two grinding rollers 335 have an annular groove in the middle of their circumferential side, and both ends of the annular groove are rounded. This is used to directly form a rounded rotating surface at the corner of the trimmed surface during the trimming process, thereby improving the comfort of holding the device.

[0026] Furthermore, the trimming assembly 2 33 also includes a dovetail groove 2 337 penetrating the middle of the grinding block 331 and a shaft 2 336 rotatably mounted on one side of the two pressure seats 3311 via bearings. Each pressure seat 3311 has two shafts 2 336, symmetrically arranged about the vertical central axis of the pressure seat 3311. Dovetail blocks 2 338 are slidably connected to both ends inside the dovetail groove 2 337. A column base 339 is fixedly connected to one end of each of the two dovetail blocks 2 338 extending outside the dovetail groove 2 337. A shaft 3310 is rotatably mounted on the axis of each of the two column bases 339 via bearings. The pressure seat 3311 is composed of an integrally formed square column and a semi-elliptical column (see...). Figure 9 Both 339 pillars are located between the curved sides of the two semi-elliptical cylinders.

[0027] Furthermore, the trimming assembly 2 33 also includes a drive adjustment component, which includes a U-shaped frame 3312 fixed to one side of one of the pressure seats 3311 and guide wheels 3313 fixedly sleeved on the outside of each shaft 1 334, shaft 2 336 and shaft 3310. The multiple guide wheels 3313 are arranged vertically and coplanarly, and a transmission belt is wound around the multiple guide wheels 3313. The shaft 2 336 can be guided and limited by the guide wheels 3313 fixedly sleeved on its outside to ensure the stability of the wrap angle formed between the guide wheels 3313 on the two shafts 1 334 and the transmission belt. A motor 2 for driving the corresponding shaft 1 334 to rotate is fixedly installed on the inside of the U-shaped frame 3312. The drive adjustment component also includes a partition block 3314 fixed in the middle of the dovetail groove 337 and a cylinder 3315 fixed on the partition block 3314 extending to one end of the dovetail groove 337. Springs 3316 are fixedly connected to both sides of the partition block 3314 and the corresponding dovetail block 338. When the longitudinal distance between the two grinding rollers 335 is at its maximum but does not leave the area where the corresponding straight guide groove 332 is located, the two springs 3316 are always in a stretched state. In this way, it can be ensured that the two column seats 339 are always tightly locked between the two arc areas of the two semi-elliptical cylinders. The cylinder 3315 is a double extension cylinder.

[0028] It should be noted that before starting the trimming process, the two grinding rollers 335 are positioned at their furthest point in the longitudinal direction, and this state is considered the initial state. During the trimming process at the port of the target trash can, after the second pushing component 32 pushes the second trimming component 33 to the processing area at the port of the target trash can, and the two grinding rollers 335 are positioned on the upper and lower annular surfaces of the port, the third cylinder 3315 pulls the two pressure seats 3311, which are in the initial state, to move towards each other. During this process, as the two pressure seats 3311 gradually approach each other, the two column seats 339 move in opposite directions under the opposing pressure of the two semi-elliptical cylinders, further stretching the two springs 3316. Simultaneously, as the two pressure seats 3311 gradually approach each other, the two sliding seats 333 drive the corresponding two grinding rollers 335 to move synchronously towards each other. When the two grinding rollers 335 move towards each other and make interference contact with the surface to be trimmed at the target trash can port position, the second motor is started to drive the corresponding shaft 334 to rotate. Under the action of the transmission belt, the other shafts 334, 336, and 3310 also rotate with the corresponding guide wheel 3313. In this way, the two grinding rollers 335 can be driven to rotate simultaneously, thereby completing the synchronous trimming of the upper and lower annular surfaces at the target trash can port position. At the same time as trimming, the corners of the trimmed surface are rounded, so that the corners of the trimmed surface directly form a rounded rotating annular surface, improving the comfort when holding. In addition, while trimming the upper and lower annular surfaces at the target trash can port position, the circumferential side annular surface of the grinding block 331 that fits the surface of the target trash can port position is also used for trimming. Conversely, the trimming state can be released by pushing the two pressure seats 3311 to move in opposite directions through cylinder 3315, and the vertical restriction on the target trash can can be released by pushing the trimming component 2 33 to reset through the push component 2 32, making it convenient to replace the target trash can.

[0029] Furthermore, such as Figure 7 As shown, the rotary drive mechanism 4 includes a gear ring 42 fixedly sleeved on the top of the outer side of the ring disk 31 and a motor 3 fixedly installed on the bottom of the concave ring platform. The output shaft end of the motor 3 is fixedly connected to a gear 41 that meshes with the gear ring 42.

[0030] It should be noted that during the process of driving the two grinding rollers 335 to rotate and simultaneously trim the upper and lower annular surfaces at the port of the target garbage can, the motor 3 also drives the gear 41 to rotate, and the rotating gear 41 drives the meshing gear ring 42 to rotate, and the rotating gear ring 42 drives the ring disk 31 to rotate, thereby enabling the two trimming components 33 to perform rotary trimming on the surface of the target garbage can to be trimmed, thus improving the trimming efficiency.

[0031] Example 2: Refer to the appendix of the instruction manual. Figures 1-4 and Figure 11 This embodiment is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the top of the frame 1 is also provided with a side hole trimming mechanism 2. The side hole trimming mechanism 2 includes a support tray 21 fixed at the center of the inner cavity of the concave ring platform, a plurality of (eight in this invention are used as an example) push components 22 fixed at the top edge of the support tray 21 in a ring array, and trimming components 23 installed on each push component 22. The positioning countersunk holes 5 for pre-positioning the plastic trash can are opened on the top of the support tray 21. It is proposed to set the number of positioning countersunk holes 5 to better align the trimming components 23 with the side hole of the target trash can after clamping and positioning. The support tray 21 is rotatably mounted on the inner side of the ring plate 31 through a bearing. The rotary drive mechanism 4 can also perform longitudinal grinding on the side hole of the trash can while the port trimming mechanism 3 rotates and grinds the trash can port.

[0032] It should be noted that, in the process of trimming the side hole of the target trash can using the present invention, after the target trash can is placed on the top of the support tray 21 and pre-limited by the positioning countersunk hole 5, the trimming component 23 is pushed towards the target trash can by the pushing component 22 and enters the corresponding side hole, and then the trimming component 23 is started to perform the trimming process.

[0033] Furthermore, such as Figures 4-5 As shown, the propulsion assembly 22 includes a dovetail groove 221 formed on the circumferential side of the support tray 21 and an L-shaped frame 225 fixed to the top of the support tray 21 at the port of the dovetail groove 221 by locking bolts. The lower surface of the horizontal section of the L-shaped frame 225 moves in contact with the upper surface of the ring disk 31. In order to reduce the frictional resistance when the two slide relative to each other, rolling balls can be fixedly embedded on the lower surface of the horizontal section of each L-shaped frame 225 to convert static friction into rolling friction. This not only reduces frictional resistance but also reduces the noise generated when the two slide relative to each other. A dovetail block 222 is slidably connected inside the dovetail groove 221.

[0034] Furthermore, the propulsion assembly 22 also includes a cylinder 226 fixedly installed on the top of the L-shaped frame 225 and a vertical frame 223 fixedly installed on the top of the dovetail block 222. The telescopic end of the cylinder 226 is fixedly connected to the vertical frame 223. A clamping block 224 is fixedly connected to the bottom of one side of the vertical frame 223. The side of the clamping block 224 facing the target trash can is set as an arc surface that fits against the outer surface of the target trash can to better clamp the target trash can. A horizontal plate 227 is fixedly provided on the other side of the vertical frame 223, and an inclined support 228 is fixedly connected between the horizontal plate 227 and the vertical frame 223 to improve the torsional resistance of the vertical frame 223.

[0035] It should be noted that during the trimming process of the inner wall of the side hole of the target trash can, after the target trash can is placed, the trimming component 2 33 is first pushed to the port position of the target trash can using the pushing component 2 32, and the upper and lower annular surfaces of the port position of the target trash can are engaged by the two grinding rollers 335. Then, the vertical frame 223 is pushed along the direction of the dovetail groove 221 towards the target trash can by the cylinder 1 226, so that the clamping block 224 set on one side of the vertical frame 223 presses against the outer wall of the target trash can. In this way, the trimming component 2 33 and the clamping block 224 can be used together to clamp and position the target trash can. At this time, the trimming part on the trimming component 23 is inserted into the corresponding side hole.

[0036] Furthermore, such as Figure 4 and Figure 6 As shown, the trimming assembly 23 includes a cross groove 231 opened at the upper end of the vertical frame 223. A cross block 232 is slidably connected inside the cross groove 231. A U-shaped frame 233 is fixedly provided on one side of the cross block 232. A grinding column 234 is rotatably installed at the center of the cross block 232 through a bearing. A motor for driving the grinding column 234 to rotate is fixedly installed inside the U-shaped frame 233.

[0037] Furthermore, the trimming assembly 23 also includes two guide rods 236 fixed inside the cross groove 231 and a horizontal shaft 235 fixed in the middle of the outer side of the U-shaped frame 233. The pressing block 34 has an irregularly shaped slot on the side facing the direction of rotation of the trimming assembly 33. The horizontal shaft 235 in the initial state is located inside the corresponding irregularly shaped slot. As the pressing block 34 rotates along the circumference of the target trash can with the trimming assembly 33, it pushes the horizontal shaft 235 along the inner side of the irregularly shaped slot. The irregular arc surface moves, and the two guide rods 236 move through the corresponding ends of the cross block 232. The outer sides of the two guide rods 236 are movably sleeved with springs 237 located below the cross block 232. When the cross block 232 is at the highest point inside the cross groove 231, the springs 237 are still in a compressed state. The outer side of the horizontal shaft 235 has a vertical through hole. The top of the horizontal plate 227 is fixed with a vertical shaft 238 at the position corresponding to the through hole. The top of the vertical shaft 238 is movably inserted into the through hole.

[0038] It should be noted that during the trimming process of the inner wall of the side hole of the target trash can, after the trimming component 2 33 and the clamping block 224 are used to clamp and position the target trash can, the motor 1 is started. The high-speed rotation of the grinding column 234 is used to trim the inner wall of the corresponding side hole. In addition, during the process of driving the grinding column 234 to rotate and trim the inner wall of the corresponding side hole, the pressure block 34, which rotates with the pushing component 2 32, will intermittently squeeze the horizontal shaft 235 at the corresponding position. The specific squeezing process is as follows: As the pressure block 34 rotates synchronously with the second propulsion component 32, the horizontal shaft 235 gradually enters the upper end of the irregular groove on the pressure block 34 at that position and contacts the inner arc surface of the irregular groove (see...). Figure 2-Figure 3 Then, as the pressure block 34 continues to rotate, it gradually squeezes the corresponding horizontal shaft 235 and pushes it downward along the vertical shaft 238. At the same time, the downward horizontal shaft 235 drives the cross block 232 downward and the high-speed rotating grinding column 234 downward, achieving comprehensive trimming of the inner wall of the side hole. During the process of pushing the horizontal shaft 235 downward, the downward cross block 232 continues to squeeze the spring 237 downward along the direction of the guide rod 236, allowing the spring 237 to fully store force. After the pressure block 34 releases the pressure on the corresponding horizontal shaft 235, the cross block 232 will instantly return to its initial position. In this way, while trimming the ring surface at the target trash can port, comprehensive trimming of the inside of the side hole of the can body can also be achieved, greatly improving trimming efficiency.

[0039] In the above technical solution, the three motors mentioned all use servo drivers of model JSDL2-10A1; the cylinders 226 and 322 mentioned both use single-acting cylinders of model DSA25N200; and the cylinder 3315 mentioned uses a double-extend rod type ESFD standard cylinder.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
