Description

Technical Field

[0001] This utility model relates to the technical field of internal cleaning equipment, and in particular to a portable mold cleaner. Background Technology

[0002] Hot stamping, as a high-end printing and decoration technique, is widely used in the surface treatment of various packaging materials and printed materials, giving products a unique texture and visual effect. However, there are some technical challenges in the hot stamping process, one of which is the problem of cleaning the mold.

[0003] During hot stamping, as gold powder is transferred to the hot stamping board under high temperature and pressure, some powder inevitably spills and accumulates in the gaps of the hot stamping die. This not only affects the quality of the hot stamping but may also damage the die. Therefore, hot stamping dies need to be cleaned regularly to maintain their good condition.

[0004] Existing mold cleaning methods have some shortcomings. First, the cleaning process usually requires operators to stop the machine and clean the mold manually after it has been in use for a period of time. This step involves spraying the mold with a cleaning agent, and then the worker must wear clean gloves and carefully wipe the mold with a lint-free cloth. Because the hot stamping plate gets very hot during the hot stamping process, workers must also wear heat-resistant gloves to avoid burns, which increases the complexity and danger of the operation.

[0005] Furthermore, traditional cleaning methods are not only time-consuming, but also prone to inconsistent cleaning results due to variations in manual operation. The chemical cleaning agents used in the process may also pollute the environment and pose a threat to the health of operators. Therefore, existing hot stamping die cleaning methods suffer from low cleaning efficiency, high labor intensity, poor safety, and environmental pollution, thus requiring improvement.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The portable mold cleaner provided by this utility model is mainly used for cleaning hot stamping molds. It can automatically suck up the gold powder on the hot stamping mold through a dust suction device and a wiping device, and wipe it with a cleaning cloth with a cleaning agent to restore the hot stamping mold to cleanliness. Compared with the existing ones that require manual wiping, this cleaner is safer and more efficient. Moreover, this cleaner is portable and can be used anytime, anywhere, which is very convenient. It does not require changing the structure of the printing equipment and can also be used to clean multiple printing equipment, realizing multi-purpose use and reducing production costs.

[0026] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a portable mold cleaner, comprising an operating handle 1, an operating lever 2, and a cleaning box 3. The two ends of the operating lever 2 are connected to the operating handle 1 and the cleaning box 3, respectively. The cleaning box 3 contains a dust suction device 4, a wiping device 5, and a control device 6. The dust suction device 4 and the wiping device 5 are electrically connected to the control device 6. During cleaning, the dust suction device 4 removes dust and impurities from the mold, and then the wiping device 5 wipes the mold. The control device 6 controls the dust suction device 4 and the wiping device 5 to automatically clean the mold, eliminating the need for manual wiping, thus improving cleaning efficiency and production efficiency. It ensures cleaning quality and avoids the risk of burns from the mold during manual wiping, as well as the risk of re-contamination caused by dust and impurities introduced during manual wiping. Furthermore, the cleaning position is controlled by the operating handle 1 and the operating lever 2 during the cleaning process, allowing the operator to clean the mold without bending over, ensuring operational flexibility and stability, and making it extremely convenient to use.

[0027] The wiping device 5 includes a solvent box 51, an unwinding roller 52 for unwinding the cleaning cloth 56, a positioning roller 53 for positioning the wiping position, a winding roller 54 for winding the cleaning cloth 56, and an air supply assembly (not labeled in the figure). The solvent box 51 has a liquid outlet 511. The positioning roller 53 is located at the liquid outlet 511. The cleaning cloth 56 unwinding by the unwinding roller 52 is wound around the positioning roller 53 and wound up by the winding roller 54. The air supply assembly is connected to the solvent box 51 and blows air into the solvent box 51, causing the solvent to spray from the liquid outlet 511 onto the cleaning cloth 56 on the positioning roller 53, so that the cleaning cloth 56 wipes the mold during the winding process.

[0028] During operation, the air supply component is first activated, causing the solvent to be sprayed out and adhere to the cleaning cloth 56 passing through the positioning roller 53. Then, the take-up roller 54 winds up the cleaning cloth 56 to a preset length, positioning the solvent-laden portion of the cloth 56 at the wiping position. This allows the cleaning cloth 56 to contact the wiping area of ​​the mold, thus wiping the mold. This novel invention allows for solvent spraying and wiping during the continuous winding of the take-up roller 54, resulting in a high degree of automation. Alternatively, the take-up roller 54 can rotate a preset length, pause winding, and then wipe the mold before winding up the preset length again for the next wiping action, saving solvent or cleaning cloth. The wiping device 5 effectively cleans the mold surface, avoiding the problems of insufficient cleanliness and low efficiency that may result from manual wiping. Furthermore, the uniform distribution of the solvent and the continuous movement of the cleaning cloth 56 ensure consistent cleaning results and rapid drying of the mold.

[0029] The positioning roller 53 is located at the liquid outlet 511 and can also contact the liquid outlet 511. The liquid outlet 511 needs to be opened when the air supply component blows air to prevent the solvent from flowing to places other than the cleaning cloth 56 during spraying, such as the ground or printing equipment, and to prevent the solvent in the solvent box 51 from directly contacting the cleaning cloth 56. It also ensures that there will be no dripping or leakage at the liquid outlet 511 after the cleaner is turned off (e.g., dripping or leakage will occur due to improper placement, tipping or impact of the cleaner).

[0030] The cleaning cloth 56 is a dust-free cloth, which has the advantages of high water absorption, softness, and excellent dust removal effect. It will not damage the mold surface during the wiping process, and will not leave particles or liquids. It has strong cleaning ability.

[0031] Please continue to refer to Section 1 through... Figure 3 The dust collection device 4 includes a dustbin 41 and a roller brush 42. The roller brush 42 is located on one side of the dustbin 41, which has a suction port 411. The dustbin 41 is connected to an air supply component. While the roller brush 42 cleans the mold, the air supply component supplies air, creating a negative pressure at the suction port 411 of the dustbin 41 to suck up dust and clean the mold surface. During use, the operator starts the dust collection device 4, and the roller brush 42 begins to rotate, contacting the mold surface for cleaning. Simultaneously, the air supply component inflates, creating a negative pressure at the suction port 411 of the dustbin 41, sucking in and effectively collecting dust, thus avoiding secondary dust pollution.

[0032] The waste bin 41 is a key component of the vacuuming device 4, comprising an air duct 412 and a bin body 413. The air duct 412 is located at the top of the waste bin 41, with an air intake 414 between the air duct 412 and the bin body 413. A dust suction port 411 is located at the bottom of one end of the bin body 413. One end of the air duct 412 has an air outlet 415, and the other end has an air inlet 416 connected to the air supply assembly. The dust suction port 411 and the air inlet 416 are diagonally positioned. According to Bernoulli's principle, in fluids (including liquids and gases), pressure is lower where the flow velocity is higher, and higher where the flow velocity is lower. When airflow passes through the air duct 412 at the top, the pressure inside the waste bin 41 decreases, creating a suction force that draws in dust (such as...). Figure 3 (As shown). Furthermore, setting the suction port 411 and the air inlet 416 diagonally helps optimize the airflow path and improve suction efficiency.

[0033] An oblique shielding part 417 is provided at the air intake 414. The oblique shielding part 417 can prevent dust from directly entering the air passage 412 and protect the air passage 412 and the dust collection system from running smoothly.

[0034] Please refer to the following: Figure 4 The control device 6 includes a motor 61, a gearbox 62, a take-up gear 63 disposed on one side of the take-up roller 54, a garbage cleaning gear 64 disposed on one side of the roller brush 42, and a control component 65 disposed on the operating lever 2. The take-up gear 63 can be connected to the gear on the take-up roller 54 via a synchronous belt or chain, so that the take-up roller 54 rotates synchronously when the motor 61 drives the take-up gear 63 to rotate. The synchronous garbage cleaning gear 64 can also be connected to the roller brush 42 via a synchronous belt or chain, so that the roller brush 42 rotates synchronously when the motor drives the garbage cleaning gear 64 to rotate.

[0035] The winding gear 63 and the waste cleaning gear 64 are spaced apart. The gearbox 62 is connected to the motor 61. The control component 65 can be a control key, located on the operating handle 1 and electrically connected to the motor 61 to control the forward and reverse rotation of the motor 61. The motor 61 controls the gearbox 62 to mesh with the winding gear 63 or the waste cleaning gear 64, causing the winding roller 54 to rotate and wind up, or causing the roller brush 42 to rotate. During use, the operator selects the sweeping or wiping function according to the cleaning needs, achieving precise control of the cleaning process. Specifically, the operator operates the control component 65 to engage the gearbox 62 with the waste cleaning gear 64, causing the roller brush 42 to rotate, thus achieving the effect of cleaning the mold surface. At the same time, the air supply component blows air into the air inlet 416, causing the dust suction port 411 to suck up dust. When the operator operates the control unit 65 to engage the gearbox 62 with the winding gear 63, the winding roller 54 starts to wind up, allowing the cleaning cloth 56 to contact the mold and be wound up. Before winding up, the air supply component blows air into the solvent box 51, causing the liquid outlet 511 to spray solvent onto the cleaning cloth 56. Then, the cloth is wound up so that the area sprayed with solvent is in the wiping position, achieving the wiping effect.

[0036] The transmission 62 includes a first transmission gear 621, a second transmission gear 622, and a main shaft 623. The first transmission gear 621 and the second transmission gear 622 are spaced apart on the main shaft 623. The winding gear 63 and the waste cleaning gear 64 are respectively disposed between the first transmission gear 621 and the second transmission gear 622, or the first transmission gear 621 and the second transmission gear 622 are disposed between the winding gear 63 and the waste cleaning gear 64.

[0037] Optionally, the motor can be a DC motor, which has good starting torque and speed regulation performance, and the speed and torque can be adjusted by changing the supply voltage or using a motor controller. The transmission can be a gear transmission, which can convert the high-speed, low-torque output of the motor into a low-speed, high-torque output, suitable for applications requiring high torque output.

[0038] like Figure 4 As shown, the winding gear 63 is positioned higher than the garbage cleaning gear 64. The motor has two gears. When the winding gear 63 and the garbage cleaning gear 64 are positioned between the first transmission gear 621 and the second transmission gear 622, when the motor is operating in the first gear, the first transmission gear 621 engages with the winding gear 63 when the main shaft 623 moves downward, and winding can begin. When the motor is operating in the second gear, the second transmission gear 622 engages with the garbage cleaning gear 64 when the main shaft 623 moves upward, and the roller brush can rotate to perform cleaning.

[0039] Similarly, when the first transmission gear 621 and the second transmission gear 622 are positioned between the take-up gear 63 and the waste cleaning gear 64, the second transmission gear 622 meshes with the waste cleaning gear 64 when the main shaft 623 moves downward, and the first transmission gear 621 meshes with the take-up gear 63 when the motor gear is switched to move the main shaft 623 upward. Both of these structures can achieve the engagement of the transmission 62 with the take-up gear 63 and the waste cleaning gear 64 respectively; either structure can be selected, and there is no limitation here.

[0040] Of course, in other embodiments, two motors can be used to control the rotation state of the winding gear 63 and the garbage cleaning gear 64 respectively, and control the winding of the cleaning cloth and the rotation of the roller brush for cleaning. This utility model does not limit this.

[0041] like Figure 1 As shown, the air supply assembly includes an air supply pipe 55 and a valve 57 for controlling the on / off state of the air pipe. The operating lever 2 has a through hole (not labeled in the figure) through which the air supply pipe 55 passes. One end of the air supply pipe 55 is connected to the waste bin 41 and the solvent box 51 respectively. Specifically, one end of the air supply pipe 55 is provided with a T-connector, which is connected to one end of the air supply pipe 55, the waste bin 41 and the solvent box 51 respectively. The other end of the air supply pipe 55 is connected to the air supply device of the printing equipment (not shown in the figure). The valve 57 is provided on the operating handle 1, which makes it convenient for the operator to control the on / off state of the valve 57 with one hand. At the same time, the operator can also operate the control component 65 to open and close and move the cleaner with one hand.

[0042] In this embodiment, the air supply pipe 55 connects to the air supply device on the printing equipment, avoiding the need for an additional air pump, which would increase the equipment cost of the automatic cleaner. Furthermore, it makes the automatic cleaner's structure simpler and more portable. Of course, adding an air pump to supply air to the vacuuming device 4 and the wiping device 5 should also be within the scope of this invention, and is not limited here.

[0043] When mold cleaning is required, the operator connects the other end of the air supply pipe 55 to the air supply device of the printing equipment, and then activates the dust suction device 4 via the control device 6 to suck up the dust on the mold surface. At this time, the air supply component works to create negative pressure at the suction port 411 to suck up dust, while solvent is sprayed from the liquid outlet 511 onto the cleaning cloth 56. Subsequently, the motor reverses, causing the winding gear 63 to rotate so that the cleaning cloth sprayed with solvent comes into contact with the mold, wiping the mold during the cleaning process. During this process, the air supply component is not working. This continuous cleaning process can be completed without manual intervention, which significantly improves cleaning efficiency and ensures cleaning quality, while also avoiding the risks of burns and scratches that may occur during manual wiping.

[0044] During the cleaning process, the operator can easily control the cleaning position using handle 1 and lever 2, greatly improving operational flexibility and stability. The automated cleaning process significantly reduces the operator's workload. This not only improves work comfort but also enhances operational safety.

[0045] In summary, the portable mold cleaner provided by this utility model includes an operating handle, an operating rod, and a cleaning box. The two ends of the operating rod are connected to the operating handle and the cleaning box, respectively. The cleaning box contains a vacuuming device, a wiping device, and a control device. Both the vacuuming and wiping devices are electrically connected to the control device. The vacuuming device removes dust and impurities from the mold, and the wiping device then wipes the mold. The control device automatically cleans the mold using the vacuuming and wiping devices, eliminating the need for manual wiping. This significantly improves cleaning efficiency and ensures cleaning quality, while also avoiding the risks of burns and scratches that may occur during manual wiping. Furthermore, the operator can easily control the cleaning position during the wiping process using the operating handle and operating rod, ensuring operational flexibility and stability. It is extremely easy to use, reducing the operator's workload and improving work comfort and safety.
