Description

Technical Field

[0001] This utility model belongs to the technical field of cup liner processing equipment, specifically relating to a cup liner water expansion molding device. Background Technology

[0002] In the production chain of insulated containers such as thermos cups and flasks, the molding and processing of the cup liner is a core link, and its processing efficiency and quality directly determine the market competitiveness of the end product. Currently, the industry generally uses the water-expansion molding process to shape the cup liner. This process has become the mainstream technical solution for metal cup liner processing due to its advantages of good uniformity of cup liner wall thickness and high product consistency after molding.

[0003] However, existing cup liner forming equipment still faces a critical pain point in practical applications: with the upgrading of manufacturing automation, the industry is gradually introducing robotic arms as feeding and unloading components to address the low efficiency and high risk of traditional manual feeding and unloading, attempting to improve production efficiency through automation. Currently, the cost of industrial robotic arms suitable for cup liner forming is generally high. For small and medium-sized cup liner manufacturers, the high equipment purchase cost will significantly increase their financial pressure, causing most companies to hesitate and still be forced to continue using manual operation. The current industry situation shows that most small and medium-sized cup liner manufacturers have not yet achieved automated feeding and unloading due to the high cost of robotic arms, and the risks of manual operation still exist.

[0004] In summary, existing cup liner forming equipment that automates material feeding and unloading via robotic arms suffers from high procurement costs and struggles to meet the economic and practical needs of enterprises of varying sizes. Therefore, developing a new, low-cost cup liner forming device that does not rely on robotic arms is crucial for overcoming industry cost bottlenecks and driving automation upgrades across the entire sector. This is of great significance for lowering the automation threshold for small and medium-sized manufacturing enterprises and improving the economic efficiency of cup liner production.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0028] like Figures 1 to 6 The cup liner water expansion molding device shown includes a molding machine 1, an integrated feeding and unloading assembly 2, a enclosure 3 and a control box 4;

[0029] The molding machine 1 includes a worktable 101, a support frame 102, and a hydraulic assembly 103. The top of the worktable 101 is equipped with a positioning mold 104 and a drainage groove 105. The positioning mold 104 is used to hold the cup liner to be processed, and the drainage groove 105 surrounds the positioning mold 104 with an inclined bottom. The support frame 102 is mounted on the top of the worktable 101, and a sliding guide rail is provided below the frame beam. A reinforcing rib is provided in the middle of the beam. The hydraulic assembly 103 includes a high-pressure water expansion cylinder, a forming head, and a seal. The hydraulic assembly 103 is mounted on the sliding guide rail of the support frame 102 via a slider. The forming head is connected to the piston rod of the high-pressure water expansion cylinder, and the seal is used to prevent high-pressure water leakage.

[0030] The integrated feeding and picking assembly 2 is installed on one side of the workbench 101, including a vertical lifting device 201, a parallel moving device 202, a clamping frame 203, clamping arms 204, a servo motor 205, and a linkage shaft 206. The vertical lifting device 201 is connected to the parallel moving device 202 and is used to drive the parallel moving device 202 and the clamping frame 203 to move vertically; the parallel moving device 202 is connected to the clamping frame 203 and is used to drive the clamping frame 203 to move laterally; the front of the clamping frame 203 is provided with a sliding groove, and the two clamping arms 204 slide with the clamping frame 203 through the sliding groove; the servo motor 205 is installed on the back of the clamping frame 203, and the linkage shaft 206 is installed on the front of the clamping frame 203 through bearings. The output end of the servo motor 205 is connected to the linkage shaft 206 for transmission, and the two ends of the linkage shaft 206 are respectively engaged with the two clamping arms 204.

[0031] The enclosure 3 is set around the workbench 101. The bottom of the enclosure 3 is provided with a drain outlet, which is connected to a recovery pipe 301. The end of the recovery pipe 301 is connected to a filter 302. The filter 302 has a filter layer and an adsorption layer inside. The filter 302 is connected to a cooling water tank.

[0032] The control box 4 is installed on one side of the molding machine 1. It contains a PLC controller, a touch screen, a hydraulic power unit and electrical components. The control box 4 is connected to the hydraulic component 103 and the integrated feeding and picking component 2 through wiring.

[0033] The working process of this embodiment is as follows:

[0034] The operator sets parameters and starts the equipment through the touch screen of the control box 4. The integrated feeding and picking component 2 starts to work: the vertical lifting device 201 controls the parallel moving device 202 and the clamping frame 203 to descend vertically to the height of the tube blank; the parallel moving device 202 controls the clamping frame 203 to move laterally to the tube blank storage rack, the servo motor 205 drives the linkage shaft 206 to rotate, and the linkage shaft 206 pulls the two clamping arms 204 to move towards the center on the sliding groove of the clamping frame 203 to complete the clamping of the tube blank.

[0035] Subsequently, the vertical lifting device 201 drives the clamping frame 203 and the tube blank to rise vertically, and the parallel moving device 202 drives the whole to move laterally to above the positioning mold 104 of the worktable 101; the vertical lifting device 201 controls the clamping frame 203 to descend, the servo motor 205 rotates in the opposite direction, the linkage shaft 206 pushes open the two clamping arms 204, and the tube blank falls into the positioning mold 104, and the positioning mold 104 positions the tube blank.

[0036] After the tube blank is positioned, the controller controls the hydraulic assembly 103 to descend along the sliding guide rail, and the forming head extends into the tube blank. The hydraulic power unit injects high-pressure water into the forming head, and the forming head expands to push the tube blank to fit against the inner wall of the mold, maintaining the set pressure for a period of time to complete the forming; then the hydraulic power unit releases pressure, the forming head contracts, and the hydraulic assembly 103 rises to reset.

[0037] After the hydraulic component 103 is reset, the integrated feeding and picking component 2 operates again: the parallel moving device 202 and the vertical lifting device 201 work together to move the clamping frame 203 to the forming cup liner, the servo motor 205 drives the linkage shaft 206 to rotate, and the clamping arm 204 moves in opposite directions to clamp the cup liner; the vertical lifting device 201 rises and the parallel moving device 202 moves laterally to transfer the cup liner to the finished product storage area; the servo motor 205 rotates in the opposite direction, the clamping arm 204 is released, and the cup liner is placed in place.

[0038] During processing, used and overflowing water flows into the bottom of the enclosure 3 through the drainage channel 105, and then enters the filter 302 through the recovery pipe 301. After filtration and adsorption, it is recycled, reducing water waste and wastewater discharge, and lowering energy consumption and material costs. The equipment repeats the above process to achieve continuous processing. If different sizes of cup liners need to be processed, the vertical lifting device 201 stroke and the clamping arm 204 movement distance can be adjusted through the control box 4 to adapt them. This device meets the requirements of modern sustainable production, helps enterprises achieve green production, and enhances their long-term competitiveness.
