Description

Technical Field

[0001] This application relates to the technical field of thermos cup production and processing, and in particular to a CNC necking device for thermos cups. Background Technology

[0002] Currently, insulated cups are generally made of stainless steel with a vacuum layer to hold water. In the field of stainless steel insulated cup manufacturing, the mouth of the insulated cup is usually narrowed.

[0003] One related technology involves a vertical neck-reducing machine for insulated cups. It includes a base, a motor mounted on the base, a positioning block connected to the motor's drive shaft, a lifting and pressing block on the base, a slide table, and an X-axis and Z-axis feed servo system connected to the slide table. Rollers for necking the cup's opening are rotatably mounted on the slide table. When necking the insulated cup, since both ends are open, the bottom of the cup is first placed on the positioning block, which abuts against the inner wall of the cup. Then, the lifting and pressing block is inserted into the top of the cup. The motor is started, causing the positioning block and the cup on it to rotate. The X-axis and Z-axis feed servo system controls the slide table to slide on the base, moving the rollers closer to or further away from the cup. When the rollers abut against the outer wall of the cup, the cup deforms and necks.

[0004] Regarding the aforementioned technologies, manual operation is required when picking up and placing cups. When processing a large number of cups, manual labor is required, resulting in limited automation and low production efficiency, which needs to be improved. Summary of the Invention

[0005] The purpose of this application is to provide a CNC necking device for thermos cups, which has the advantages of reducing manual labor, increasing the degree of automation, and improving production efficiency.

[0006] The technical solution of the CNC neck-shrinking device for thermos cups provided in this application is as follows:

[0007] A CNC neck-reducing device for thermos cups includes a workbench and a work frame mounted on the workbench. Rollers for necking the cup opening are slidably mounted on the work frame. A positioning block is mounted on the workbench via a motor, and a compaction block is also mounted on the workbench with vertical movement. A support is mounted on one side of the workbench, and a storage platform is mounted at the top of the support. A material conveying assembly is positioned between the support and the workbench to transport the cup from the storage platform to the positioning block. A storage box is mounted on the storage platform, with an inlet at the top and a feeding port at the bottom. The storage platform has a discharge port. A guide plate is inclinedly arranged on the surface of the storage platform. A pair of limiting plates are arranged on the storage platform and the guide plate. The discharge port is located between the two limiting plates. A discharge port is opened on the surface of the storage platform and between the two limiting plates. A discharge cylinder is arranged below the storage platform and at the discharge port. The bottom end of the discharge cylinder is sealed. The top end of the discharge cylinder is connected to the discharge port. A discharge groove for the cup to pass through is opened on the side wall of the discharge cylinder. A pusher cylinder is arranged on the storage platform. The piston rod of the pusher cylinder is connected to a pusher plate, which is located between the two limiting plates.

[0008] By adopting the above technical solution, workers can pre-place batches of insulation board cups into the storage box through the inlet. The cups will be horizontal in the storage box. The batch of cups will accumulate in the storage box and fall onto the storage platform through the outlet. Since the outlet is located between two limiting plates, only one cup can fall between the limiting plates at a time. At the same time, the limiting plates limit the cup, keeping it between the two limiting plates on the storage platform. Then, the pusher cylinder works, and the piston rod of the pusher cylinder extends, causing the pusher plate to abut against the bottom of the cup on the storage platform, driving the cup to slide towards the guide plate. The top of the cup will abut against the guide plate, and at the same time, the limiting plates limit the cup, allowing the cup to tilt on the guide plate. Then push... The piston rod of the feeding cylinder retracts, causing the pusher plate to move away from the guide plate. At this time, under the action of gravity, the cups on the guide plate will slide into the discharge port and fall into the discharge cylinder. The discharge cylinder is set vertically, thus transporting the batch of horizontally stacked cups vertically into the discharge cylinder. Then, the feeding component takes the cups out of the discharge cylinder through the discharge chute and transports them to the positioning block. Finally, the cups are compacted on the positioning block by the compaction block and the opening of the cups is narrowed by rollers. The whole process only requires storing the cups to be processed in batches in the storage box, and then repeatedly feeding the cups by extending and retracting the pusher cylinder. There is no need for manual handling of cups, which reduces manual labor, improves the automation level of the equipment, and thus improves production efficiency.

[0009] Optionally, the material handling assembly includes a guide rail, a lead screw rail, a connecting block, a lifting cylinder, a rotary cylinder, and a pneumatic gripper. The guide rail and the lead screw rail are fixedly installed between the support and the worktable. One end of the connecting block is slidably connected to the guide rail, and the other end of the connecting block is threadedly connected to the lead screw on the lead screw rail. The lifting cylinder is installed on the connecting block, and the rotary cylinder is connected to the piston rod of the lifting cylinder. The pneumatic gripper is installed on the rotating shaft of the rotary cylinder. A clamping groove is provided at the opening of the discharge chute for the pneumatic gripper to pass through.

[0010] By adopting the above technical solution, after the cup falls into the discharge cylinder, the screw slide rail operates, and the guide slide rail guides the connecting block, which can drive the connecting block to slide along the length of the guide slide rail. First, the connecting block is driven closer to the discharge cylinder, and then the pneumatic gripper on the connecting block is driven to fit over the discharge cylinder. Then, the pneumatic gripper operates, and the pneumatic gripper clamps the cup in the discharge cylinder through the clamping groove. The screw slide rail rotates in the opposite direction, driving the pneumatic gripper away from the discharge cylinder, thereby driving the cup to separate from the discharge cylinder through the discharge groove. The screw slide rail drives the pneumatic gripper closer to the worktable, and the rotating shaft of the rotary cylinder rotates 180 degrees, so that the pneumatic gripper faces the worktable. The screw slide rail drives the cup to move directly above the positioning block. At this time, the cup on the pneumatic gripper is aligned with the positioning block. Finally, the lifting cylinder retracts, so that the cup is fitted onto the positioning block, realizing the effect of transporting the cup in the discharge cylinder to the positioning block. The whole process has a high degree of automation, high control precision, and low cost.

[0011] Optionally, a pressure sensor is installed inside the discharge cylinder and on its bottom wall. The pressure sensor is connected to a processor. The lead screw slide rail, lifting cylinder, rotating cylinder, and pneumatic gripper are all interconnected with the processor. The processor is used to control the lead screw slide rail, lifting cylinder, rotating cylinder, and pneumatic gripper to work when the pressure sensor detects a pressure signal.

[0012] By adopting the above technical solution, when the cup slides from the guide plate into the discharge port and falls into the discharge cylinder, the bottom wall of the cup will abut against the pressure sensor on the bottom wall of the discharge cylinder. At this time, the pressure sensor detects the pressure signal and transmits it to the controller. The controller then controls the lead screw slide rail, lifting cylinder, rotating cylinder and pneumatic gripper to work. By setting the pressure sensor for detection, the accuracy of the equipment operation is improved.

[0013] Optionally, a set of take-up rods are provided at the bottom of the guide rail and the lead screw rail, and a take-up net is provided between the take-up rods. The bottom of the guide rail and the lead screw rail is provided with an installation groove for inserting the take-up rods and the take-up net, and the take-up rods can abut against the inner wall of the installation groove.

[0014] By adopting the above technical solution, after the work frame rollers have completed the cup-shaped necking operation, the screw guide rail drives the pneumatic gripper to approach the cup. The pneumatic gripper clamps the cup, and then the lifting cylinder extends, causing the cup to disengage from the positioning block. At this time, the screw guide rail then drives the pneumatic gripper away from the worktable, allowing the pneumatic gripper to slide above the collection net. The pneumatic gripper releases, and under the action of gravity, the processed cup falls into the collection net, thus collecting the processed cup. At the same time, the collection rod and the mounting groove can be used to detach and assemble the collection net from the guide rail and the screw guide rail, facilitating the recycling of the processed cup.

[0015] Optionally, a limiting ring is rotatably provided at the opening of the discharge trough, and a torsion spring is provided at the rotatable connection between the limiting ring and the discharge trough, the torsion spring driving the limiting ring to rotate towards the discharge cylinder.

[0016] By adopting the above technical solution, when the cup slides from the guide plate into the discharge port and falls into the discharge cylinder, the torsion spring drives the limiting ring to rotate towards the discharge cylinder. The limiting ring can limit the cup inside the discharge cylinder. When the pneumatic gripper holds the cup in the discharge cylinder and causes it to separate from the discharge cylinder, the limiting ring can rotate away from the discharge cylinder, effectively reducing the phenomenon of the cup separating from the discharge cylinder when it is inside the discharge cylinder.

[0017] Optionally, the top end of the discharge cylinder is provided with a mounting ring, and a mounting bolt that is threadedly connected to the bottom end of the storage platform is provided through the mounting ring.

[0018] By adopting the above technical solution, the mounting ring and the storage platform can be disassembled and reassembled using mounting bolts, which allows for the replacement of the material discharge cylinder with a material discharge cylinder of different diameters. This enables the processing of cups and cylinders of different diameters and improves the applicability of the equipment.

[0019] Optionally, the storage bin includes a box body, a curved pipe, and a vertical pipe. The box body is fixedly mounted on the storage platform, the curved pipe is disposed inside the box body, the inlet is disposed on the box body and communicates with one end of the curved pipe, the other end of the curved pipe is communicated with the vertical pipe, and the outlet is disposed at the end of the vertical pipe away from the curved pipe.

[0020] By adopting the above technical solution, more cups can be stored in the curved tube. After the cups are put into the feed inlet, they can slide in the curved tube. The curved tube can reduce the sliding speed of the cups, buffer them, and reduce the damage caused by collisions between the cups. Finally, the cups enter the vertical tube through the curved tube. The entire storage box can not only store a large number of cups to be processed, but also protect the cups. At the same time, the storage box occupies little space, effectively utilizing the factory space.

[0021] Optionally, a photoelectric counter is provided on the inner wall of the curved pipe, and the photoelectric counter is used to calculate the number of cups entering the curved pipe.

[0022] By adopting the above technical solution, after the cup is placed into the curved tube through the feed port, when the cup passes through the photoelectric counter, the photoelectric counter can sense the signal and calculate the number of cups entering the curved tube through the processor, which makes it convenient to count the number of processed cups.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. By setting up a support frame, storage platform, storage box, inlet, outlet, guide plate, limit plate, drop outlet, drop cylinder, discharge trough, pusher cylinder and pusher plate, batches of insulation board cups are put into the storage box from the inlet. The pusher cylinder drives the cups on the guide plate to slide into the drop outlet and fall into the drop cylinder. The whole process only requires storing the cups to be processed in batches in the storage box, and then feeding the cups repeatedly by extending and retracting the pusher cylinder. There is no need for manual handling of cups, which reduces manual labor, improves the automation level of the equipment, and thus improves production efficiency.

[0025] 2. By setting up guide rails, lead screw rails, connecting blocks, lifting cylinders, rotating cylinders, and pneumatic grippers, when the cup falls into the discharge cylinder, the lead screw rail drives the pneumatic grippers on the connecting block to fit over the discharge cylinder. The rotating shaft of the rotating cylinder rotates 180 degrees, and the lead screw rail moves the cup to directly above the positioning block, so that the cup is fitted onto the positioning block, thus achieving the effect of transporting the cup from the discharge cylinder to the positioning block. The whole process has a high degree of automation, high control precision, and low cost.

[0026] 3. By setting up a box body, a curved pipe, and a vertical pipe, more cups can be stored in the curved pipe. After the cups are put into the feed inlet, they can slide in the curved pipe. The curved pipe can reduce the sliding speed of the cups and buffer them, reducing the damage caused by collisions between cups. Finally, the cups enter the vertical pipe through the curved pipe. The entire storage box can not only store a large number of cups to be processed, but also protect the cups. At the same time, the storage box occupies little space, making effective use of factory space. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.

[0032] A CNC neck-shrinking device for thermos cups, as described in the following example. Figure 1 The system includes a workbench 1 and a work frame 11 mounted on the workbench 1. Rollers 111 are slidably mounted on the work frame 11 for narrowing the mouth of the cup. A positioning block 12 is mounted on the workbench 1 via a motor, with its top end angled. A compaction block 13 is also mounted on the workbench 1 via a hydraulic cylinder. When the cup is placed on the positioning block 12, the compaction block 13 descends and inserts into the top of the cup to compact it. Then, the positioning block 12 rotates, and the rollers 111 approach and abut against the cup to narrow its mouth.

[0033] Reference Figure 1 and Figure 2A support 2 is provided on one side of the workbench 1, and a storage platform 21 is fixedly provided on the top of the support 2. The storage platform 21 is horizontally arranged, and a material conveying component 3 is provided between the support 2 and the workbench 1. A storage box 4 is provided on the storage platform 21. The top of the storage box 4 has a feed inlet 411, and the bottom of the storage box 4 has a discharge outlet 412. The storage box 4 includes a box body 41, a curved pipe 42, and a vertical pipe 43. The box body 41 is fixedly provided on the storage platform 21. The curved pipe 42 is located inside the box body 41. The feed inlet 411 is located on the box body 41 and is connected to one end of the curved pipe 42. The other end of the curved pipe 42 is connected to the vertical pipe 43. The vertical pipe 43 is arranged in a vertical direction, and the discharge outlet 412 is located at the end of the vertical pipe 43 away from the curved pipe 42. By horizontally placing the cup into the feed inlet 411, the cup is inserted into the curved pipe 42 through the feed inlet 411. The cup can slide within the curved pipe 42, which reduces the sliding speed of the cup and buffers it, reducing the possibility of damage caused by collisions between cups. Finally, the cup enters the vertical pipe 43 through the curved pipe 42. The entire storage box 4 can not only store a large number of cups to be processed, but also protect the cups. At the same time, the storage box 4 occupies little space, effectively utilizing the factory space.

[0034] Reference Figure 2 A photoelectric counter 8 is installed on the inner wall of the curved tube 42. After the cup is put into the curved tube 42 through the feed port 411, the photoelectric counter 8 can sense the signal and calculate the number of cups entering the curved tube 42 through the processor, so as to facilitate the counting of the number of processed cups.

[0035] Reference Figures 1 to 3A guide plate 211 is fixedly installed at one end of the storage platform 21 facing the workbench 1. The guide plate 211 is inclined. A pair of limiting plates 212 are fixedly installed on both the storage platform 21 and the guide plate 211. The discharge port 412 is located between the two limiting plates 212. A discharge port 22 is provided on the surface of the storage platform 21 between the two limiting plates 212. The discharge port 22 is square. A discharge cylinder 5 is provided below the storage platform 21 and at the discharge port 22. The discharge cylinder 5 is arranged vertically. The bottom end of the discharge cylinder 5 is sealed. The top end of the discharge cylinder 5 is connected to the discharge port 22. A discharge groove 51 for the cup to pass through is provided on the side wall of the discharge cylinder 5. A pusher cylinder 6 is fixedly installed on the storage platform 21 by bolts. The piston rod of the pusher cylinder 6 is connected to a pusher plate 61. The pusher plate 61 is located between two limit plates 212, and the length direction of the pusher plate 61 is set along the length direction of the limit plate 212. Under the influence of gravity, the cups inside the storage bin 4 fall from the storage bin 4 through the discharge port 412 onto the storage platform 21. The limiting plate 212 restricts only one cup to contact the surface of the storage platform 21. The piston rod of the pushing cylinder 6 extends, causing the pushing plate 61 to abut against the bottom of the cup on the storage platform 21, driving the cup to slide on the storage platform 21 towards the guiding plate 211. The top of the cup can abut against the guiding plate 211, and at the same time, the limiting plate 212 limits the cup, allowing the cup to tilt on the guiding plate 211. Then, the piston rod of the pushing cylinder 6 retracts, causing the pushing plate 61 to move away from the guiding plate 211. At this time, under the influence of gravity, the cup on the guiding plate 211 slides into the discharge port 22 and falls into the discharge cylinder 5. In this way, the piston rod of the pushing cylinder 6 repeatedly extends and retracts, thereby vertically transporting a batch of horizontally stacked cups into the discharge cylinder 5.

[0036] Reference Figure 1 and Figure 3The material handling assembly 3 includes a guide rail 31, a lead screw rail 32, a connecting block 33, a lifting cylinder 34, a rotary cylinder 35, and a pneumatic gripper 36. The guide rail 31 and the lead screw rail 32 are fixedly mounted between the support 2 and the worktable 1, and are parallel to each other. One end of the connecting block 33 is slidably connected to the guide rail 31, and the other end of the connecting block 33 is threadedly connected to the lead screw on the lead screw rail 32. The lifting cylinder 34 is fixedly mounted on the connecting block 33, and the rotary cylinder 35 is connected to the piston rod of the lifting cylinder 34. The pneumatic gripper 36 is fixedly mounted on the rotating shaft of the rotary cylinder 35, and a clamping groove 511 is provided at the opening of the discharge chute 51 for the pneumatic gripper 36 to pass through. When the cup falls into the discharge cylinder 5, the lead screw slide rail 32 operates, and the guide slide rail 31 guides the connecting block 33, causing the connecting block 33 to slide along the length of the guide slide rail 31. First, the connecting block 33 is driven to approach the discharge cylinder 5, causing the pneumatic gripper 36 on the connecting block 33 to be sleeved on the outside of the discharge cylinder 5. Then, the pneumatic gripper 36 operates, and the pneumatic gripper 36 clamps the cup in the discharge cylinder 5 through the clamping groove 511. After clamping, the lead screw slide rail 32 rotates in the opposite direction, causing the pneumatic gripper 36 to move away from the discharge cylinder 5, thereby causing the cup to separate from the discharge cylinder 5 through the discharge groove 51. The lead screw slide rail 32 then drives the connecting block 33 to slide so that the pneumatic gripper 36 approaches the worktable 1. At the same time, the rotating shaft of the rotary cylinder 35 rotates 180 degrees so that the pneumatic gripper 36 faces the worktable 1. The lead screw slide rail 32 drives the cup to move directly above the positioning block 12. At this time, the cup on the pneumatic gripper 36 is aligned with the positioning block 12. Finally, the lifting cylinder 34 retracts so that the cup is sleeved on the positioning block 12, thus realizing the function of transporting the cup in the discharge cylinder 5 to the positioning block 12.

[0037] Reference Figure 3 A pressure sensor 9 is installed inside the discharge cylinder 5 and located on its bottom wall. The pressure sensor 9 is connected to a processor. The lead screw slide rail 32, lifting cylinder 34, rotating cylinder 35, and pneumatic gripper 36 are all connected to the processor. When the cup slides from the guide plate 211 into the discharge port 22 and falls into the discharge cylinder 5, the bottom wall of the cup will abut against the pressure sensor 9 on the bottom wall of the discharge cylinder 5. At this time, the pressure sensor 9 detects the pressure signal and transmits it to the controller. The controller then controls the lead screw slide rail 32, lifting cylinder 34, rotating cylinder 35, and pneumatic gripper 36 to work. By setting the pressure sensor 9, it is possible to accurately determine whether the cup has fallen into the discharge cylinder 5, thereby improving the accuracy of the equipment.

[0038] Reference Figure 3A limiting ring 52 is rotatably provided at the opening of the discharge trough 51. The length direction of the limiting ring 52 is set along the circumference of the discharge cylinder 5. A torsion spring is provided at the rotatable connection between the limiting ring 52 and the discharge trough 51. The torsion spring drives the limiting ring 52 to rotate towards the discharge cylinder 5. When the cup slides from the guide plate 211 into the discharge port 22 and falls into the discharge cylinder 5, the limiting ring 52 can limit the cup to stay in the discharge cylinder 5. When the pneumatic gripper 36 clamps the cup in the discharge cylinder 5 and drives it to separate from the discharge cylinder 5, the limiting ring 52 can rotate away from the discharge cylinder 5, effectively reducing the phenomenon of the cup separating from the discharge cylinder 5 when it is in the discharge cylinder 5.

[0039] Reference Figure 3 The top of the discharge cylinder 5 is provided with an installation ring 53, and an installation bolt 531 is threaded through the installation ring 53 and connected to the bottom of the storage platform 21. The installation ring 53 and the storage platform 21 can be disassembled by using the installation bolt 531, so as to realize the disassembly of the discharge cylinder 5 and the storage platform 21 to replace the discharge cylinder 5 with different diameter sizes. This can meet the processing needs of cups with different diameter sizes and improve the applicability of the equipment.

[0040] The implementation principle of this application embodiment is as follows:

[0041] Workers can pre-place a batch of insulated cups into the storage box 4 through the feed inlet 411. The cups will be in a horizontal position in the storage box 4. The batch of cups will accumulate in the curved pipe 42 and fall into the storage platform 21 one by one through the discharge port 412. The limiting plate 212 limits the cups, so that the cups are located between the two limiting plates 212 on the storage platform 21. When processing is required, the pusher cylinder 6 operates, and the piston rod of the pusher cylinder 6 extends, causing the pusher plate 61 to abut against the bottom end of the cup on the storage platform 21. This drives the cup to slide towards the guide plate 211, and the top of the cup will abut against the guide plate 211. At the same time, the limiting plate 212 limits the cup, allowing it to tilt on the guide plate 211. Then, the piston rod of the pusher cylinder 6 retracts, causing the pusher plate 61 to move away from the guide plate 211. At this time, under the action of gravity, the cup on the guide plate 211 will slide into the discharge port 22 and fall into the discharge cylinder 5. The discharge cylinder 5 is vertically set, thus vertically transporting a batch of horizontally stacked cups into the discharge cylinder 5. Then, the lead screw slide rail 32 operates, driving... The pneumatic gripper 36 clamps the cup in the discharge cylinder 5 through the clamping groove 511 and disengages the cup from the discharge cylinder 5 through the discharge groove 51. The lead screw slide rail 32 then drives the pneumatic gripper 36 to approach the worktable 1, and the rotating shaft of the rotary cylinder 35 rotates 180 degrees, so that the pneumatic gripper 36 faces the worktable 1. The lead screw slide rail 32 drives the cup to move directly above the positioning block 12. At this time, the cup on the pneumatic gripper 36 is aligned with the positioning block 12. Finally, the lifting cylinder 34 retracts, so that the cup is placed on the positioning block 12, realizing the effect of transporting the cup in the discharge cylinder 5 to the positioning block 12. The whole process has a high degree of automation, high control precision, and low cost.
