Description

Technical Field

[0001] This utility model belongs to the field of printing waste recycling technology, specifically relating to a roll-type material collection device. Background Technology

[0002] Electroplated aluminum foil is a hot stamping material made by coating a thin film substrate and then vacuum-depositing a layer of metal foil. When using electroplated aluminum foil to stamp large-area patterns, the waste foil produced after use has significant static electricity. This waste accumulates at the waste stretching roller of existing hot stamping equipment, hindering the movement of the foil and easily getting caught in the equipment, making normal production difficult. Current technologies primarily involve either letting the waste foil hang naturally into a collection box after the waste collection roller is pulled out, or using a simple collection device. However, the method of letting the waste foil hang naturally into the collection box after the waste collection roller is pulled out is prone to causing the waste foil to get caught in the equipment, resulting in machine downtime, especially when the electroplated aluminum foil has high static electricity and a long step distance. Once a certain amount of waste accumulates, it needs to be manually collected and placed into waste bags, increasing the workload of operators. When using simple collecting devices for waste foil recycling, most of these devices are complex, bulky, difficult to maintain, and inconvenient to move. Furthermore, when the accompanying hot stamping equipment is under maintenance or no longer needed, it is difficult to modify the collecting device for use with other equipment. Therefore, it is necessary to provide a roll-type collecting device suitable for collecting electroplated aluminum foil waste. Utility Model Content

The tension shaft assembly includes a linear guide rail, a tension shaft connected to the linear guide rail for reciprocating motion, an upper action sensor for stopping the take-up roller drive, and a lower action sensor for starting the take-up roller drive. The vertical height of the sliding roller is higher than the take-up roller and not lower than the upper action sensor. The vertical height of the upper action sensor is lower than the upper end of the linear guide rail and higher than the lower action sensor. The vertical height of the lower action sensor is higher than the lower end of the linear guide rail. The tension shaft descends along the linear guide rail under the action of gravity.

Detailed Implementation

[0017] See also Figure 1-4 This embodiment provides a roll-type collecting device for collecting electroplated aluminum foil waste, including a frame 2 and four collecting mechanisms disposed on the frame 2, all of which have the same structure.

[0018] In this embodiment, the receiving mechanism includes a receiving roller drive and a receiving roller 4, an auxiliary shaft 5, a sliding roller 6, a guide shaft assembly 7, and a tension shaft assembly 9 arranged at intervals along the horizontal direction. The tension shaft assembly 9 includes a linear guide rail 95, a tension shaft 93, an upper motion sensor 821 for stopping the receiving roller drive, and a lower motion sensor 822 for starting the receiving roller drive. The vertical height of the sliding roller 6 is higher than that of the receiving roller 4 and not lower than that of the upper motion sensor 821. The auxiliary shaft 5 is located horizontally between the receiving roller 4 and the sliding roller 6, and the vertical height of the auxiliary shaft 5 is between the receiving roller 4 and the sliding roller 6. The vertical height of the upper motion sensor 821 is lower than that of the upper end of the linear guide rail 95 and higher than that of the lower motion sensor 822. The vertical height of the lower motion sensor 822 is higher than that of the lower end of the linear guide rail 95.

[0019] Specifically, the frame 2 can be divided into a receiving side and a drive side according to the installed parts. The receiving roller 4 includes a drive shaft 43 and an air expansion sleeve 41 fixedly connected to the outside of the drive shaft. The air expansion sleeve 41 is provided with air injection holes 42. The outer enclosed housing of the drive shaft 43 passes through the frame 2 and is connected to the receiving side and drive side of the frame 2 respectively through bearings. Bearings are installed at both ends inside the enclosed housing. The transmission shaft flange 45, which connects to the bearing housing, is fixed to the frame 2 with screws. An air-expansion sleeve 41 is installed on the shaft body of the transmission shaft 43 on the receiving side. A transmission pulley 44 is mounted at the tail of the transmission shaft 43, and the transmission pulley 44 is connected to the drive pulley 113 via a transmission belt 115. The servo motor 114 is fixed to the motor bracket 112 with screws. The motor bracket 112 is fixed to the motor support plate 10 with screws. The motor support plate 10 is fixed to the frame 2 with countersunk hexagonal screws 14. A L-shaped bracket 15 is installed below the motor support plate 10, and the L-shaped bracket 15 is fixed to the frame 2 and the motor support plate 10 with screws. The two sides of the motor support plate 10 are connected to the frame 2 with countersunk screws 14 to ensure the strength of the motor support plate 10. Motor movement screws 111 are installed on the side of the motor bracket 112.

[0020] The upper guide shaft 71, lower guide shaft 72, and auxiliary shaft 5 are respectively adapted to mounting slots 711, 721, and 51 on the frame 2. The sliding roller 6 has a shaft in the middle, with both ends mounted on the frame 2 via bearings. Snap rings are installed on both sides of the shaft to fix the bearing positions. Bearings are installed on both sides of the sliding roller 6, and snap rings are used to lock them on the outside. The bearings reduce the force on the collected material during the collection process, making it less prone to breakage and achieving stable operation. The shaft of the sliding roller 6 on the drive side of the frame 2 has a sliding roller flange 61 connected to the bearing seat, which is fixed to the frame 2 with screws. One end of the auxiliary shaft 5 and guide shaft assembly 7 is directly installed in the perforated slot of the frame 2. A guide shaft assembly 7 is provided on the frame 2 corresponding to any receiving mechanism, used to guide different electroplated aluminum foil waste strips to different receiving mechanisms.

[0021] In this embodiment, the frame 2 has a slide rail groove 96, and the linear guide rail 95 is a vertically arranged linear slide rod, ensuring that the tensioning shaft 93 can descend along the linear guide rail 95 under the action of gravity. The linear guide rail 95 is installed in the middle of the slide rail groove 96 and is fixed to the frame 2 at the top and bottom by screws. The linear guide rail 95 has limit blocks 911 and limit blocks 912 at the top and bottom, respectively, which are fixed to the frame 2 by screws. The deceleration spring 92 is sleeved on the outside of the linear guide rail 95, and the slider 94 is installed on the linear guide rail 95. One side of the tensioning shaft 93 is fixed to the slider 94. The frame 2 has an action switch groove 81, and the upper action sensor 821 and the lower action sensor 822 are fixed by a fixing block 83. The deceleration spring 92 is nested above the linear guide rail 95. The deceleration spring 92 is located above the tensioning shaft 93 and is compressed by the tensioning shaft 93. The deceleration spring 92 is sized to match the linear guide rail 95 and the slide rail groove 96. The deceleration spring 92 is slightly larger than the linear guide rail 95 and slightly smaller than the slide rail groove 96, ensuring that the deceleration spring 92 remains above the linear guide rail 95 without slipping down, and is easy to disassemble and replace. In this embodiment, both the upper action sensor 821 and the lower action sensor 822 are photoelectric sensors. In other embodiments, the upper action sensor 821 and the lower action sensor 822 can also be proximity switches.

[0022] In this embodiment, the roll-type take-up device also includes a control box 13, a low-voltage electrical box 12, and a human-machine interface touch screen 3 located on the frame 2. The control box 13 is equipped with a programmable controller, a servo driver 131, and a cable tray 132. The controller is communicatively connected to the human-machine interface touch screen 3, the servo driver 131, the upper motion sensor 821, and the lower motion sensor 822. The human-machine interface touch screen 3 on the top of the frame 2 is connected to the servo driver and the programmable controller inside the control box 13 via a connecting cable passing through the cable tray 132, thereby controlling the servo motor 114. The bottom of the frame 2 is equipped with four casters 1, which are universal casters with brakes.

[0023] The working principle of the roll-type material receiving device in this embodiment is as follows: First, according to Figure 4The preparatory work for the material winding mode shown is as follows: the electroplated aluminum foil waste strip is sequentially wound around the guide shaft assembly 7, tension shaft 93, sliding roller 6, auxiliary shaft 5, and take-up roller 4, with the tension shaft 93 initially held in the middle position of the linear guide rail 95. When the hot stamping equipment releases the electroplated aluminum foil waste strip, the tension shaft 93 descends under gravity, along with the slider 94, along the linear guide rail 95 to below the lower motion sensor 822. The lower motion sensor 822 generates a signal and transmits it to the servo driver 131, which activates the servo motor 114. The servo motor 114 drives the drive pulley 113 to rotate, which in turn drives the drive shaft 43, which is equipped with the drive pulley 44, to rotate via the transmission belt 115. Consequently, the take-up roller 4 winds up the electroplated aluminum foil waste strip. When the released electroplated aluminum foil waste strip is almost finished rewinding, the electroplated aluminum foil waste strip is stretched, causing the tension shaft 93 to drive the slider 94 to rise together. When the slider 94 rises to the position of the upper motion sensor 821, it generates a signal and transmits it to the servo driver 131. The servo motor 114 stops running, and the slider 94 contacts the deceleration spring 92 due to inertia. The spring is compressed, and the slider 94 decelerates to zero and begins to fall. When the hot stamping equipment continues to release the electroplated aluminum foil waste strip, the slider 94 falls again under the action of gravity until it passes the lower motion sensor 822. The servo motor 114 starts to drive the take-up roller 4 to rewind. The tension shaft 93 continues to move up and down according to the release of the electroplated aluminum foil waste strip by the hot stamping equipment. During the operation, the waste is always kept taut, and the material is neatly collected.

[0024] This embodiment of the roll-type take-up device can be equipped with several independent take-up mechanisms, solving the problem of collecting different types of waste foil at different speeds. Using this device for waste collection can avoid abnormal equipment downtime caused by poor collection of electroplated aluminum waste foil. It adopts multi-axis independent control, allowing the selection of one or more axes according to the specific production conditions of the hot stamping machine to meet actual work requirements. The tension shaft uses a slider and linear guide design, with a spring added to the upper limit stroke of the linear guide for smoother up-and-down movement. A slider that can move up and down along the linear guide is provided. During the winding process, the material drives the slider on one side of the tension shaft to move up and down, triggering a photoelectric sensor to control the servo motor. The servo system operates stably, and the overall device has few mechanical components, making it less prone to failure. Bearings are present on both sides of the sliding roller and the tension shaft, adapting to the winding of finer materials with low resistance and reduced breakage. Meanwhile, the enclosed outer shell of the drive shaft passes through the panels on both sides of the frame, and bearings are installed at both ends inside the enclosed shell, which can effectively support the material on the air shaft, reduce wear between structural components, and extend the service life of the equipment; brakeable universal wheels make it easy to move; it adopts an adjustable speed servo motor and touch screen operation to improve equipment stability and operational safety.
