Description

Technical Field

[0001] This utility model relates to the field of aluminum plating machine technology, specifically a safety protection mechanism for aluminum plating machines. Background Technology

[0002] An aluminum plating machine is a device for plating aluminum film. It uses a vacuum aluminum plating process to evaporate high-purity aluminum wire into a gaseous state at high temperature. When the plastic film passes through the vacuum evaporation chamber, the gaseous aluminum molecules precipitate onto the surface of the plastic film to form a bright metallic film.

[0003] Most existing aluminum coating machines, such as the one described in the Chinese patent publication CN203429241U entitled "A Vacuum Coating Machine with a Double-Table Evaporation Trolley", include a fixed track and a vacuum chamber set on the fixed track; a winding trolley is set on the right side of the vacuum chamber; the winding trolley is slidably set on the fixed track by the wheels at its bottom.

[0004] Because there is a significant gap between the trolley and the vacuum chamber after the trolley moves out, enough for pedestrians to pass through, some people may choose to walk through this gap to avoid detours. If the trolley happens to be returning at this time, it can easily lead to a safety accident. Current methods for preventing such accidents mostly rely on company safety training to enhance the safety awareness of workshop workers and aluminum plating machine operators, without installing safety protection mechanisms on the aluminum plating machine itself. Therefore, this approach is insufficient and urgently needs to be addressed. Utility Model Content

[0005] In order to avoid and overcome the technical problems existing in the prior art, this utility model provides a safety protection mechanism for an aluminum plating machine. In addition to the traditional safety training for personnel, a safety protection mechanism is also set on the aluminum plating machine to further prevent the occurrence of safety accidents.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A safety protection mechanism for an aluminum plating machine includes a vacuum chamber, a track fixed to one side of the vacuum chamber, and a trolley sliding on the track. An interval cavity is formed between the adjacent ends of the trolley and the track. Both ends of the interval cavity are provided with blocking components. The blocking components include two telescopic stops that are hinged to each other at their adjacent ends by a horizontal rotating shaft. The opposite ends of the two telescopic stops are respectively hinged to the vacuum chamber and the trolley by horizontal hinge seats. The two horizontal hinge seats are at the same height, and the axis of the horizontal rotating shaft and the hinge axis of the horizontal hinge seats are both perpendicular to the length direction of the track.

[0008] As a further embodiment of this utility model: the adjacent ends of the telescopic stop are bent downward in an arc shape, so that the horizontal pivot at the adjacent ends of the telescopic stop is located below the axis of the telescopic stop.

[0009] As a further embodiment of this utility model: the telescopic stop bar includes a sleeve rod and an inner rod that slides coaxially inside the sleeve rod, and the sleeve rod is provided with a spring that elastically drives the inner rod to slide inward to the inside of the sleeve rod.

[0010] As a further improvement of this utility model: a control console is provided on the side of the vacuum chamber, and two start buttons are provided on the control console to start the trolley, and the trolley is started when both start buttons are pressed at the same time.

[0011] As a further improvement of this utility model, the interval between the two start buttons is 25cm-30cm.

[0012] As a further improvement of this utility model: grating sensors with output terminals connected to the control console are installed at both ends of the spacer cavity, and a switching relay for disconnecting the control circuit is installed on the control console.

[0013] As a further improvement of this utility model, it also includes a relay reset button for controlling the restart of the switch relay, with the relay reset button and the control console respectively arranged at both ends of the partition cavity.

[0014] As a further improvement of this utility model, a buzzer with an input terminal connected to a control console is installed on the vacuum chamber.

[0015] As a further improvement of this utility model, the buzzer is configured as two sets, and is respectively arranged at both ends of the spacer cavity.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. Before the trolley departs, the two telescopic levers retract and form a V-shape. As the trolley slides outward, the two telescopic levers gradually rotate into a horizontal straight structure. Then, the two telescopic levers extend outward, forming a barrier structure at both ends of the partition cavity, effectively reducing safety hazards during trolley operation. When the trolley slides inward to return, the telescopic levers retract, and their adjacent hinged ends move downward under gravity, eventually returning to the initial V-shape as the trolley gradually returns to its original position. This barrier structure formed by the two telescopic levers is not only simple in structure but also automatically folds and retracts, preventing personnel from entering from both ends of the partition cavity without affecting the normal operation of the trolley.

[0018] 2. Because the horizontal pivot is located axially below the telescopic stop bar, the telescopic stop bar can fold downwards more stably, preventing the telescopic stop bar from failing to fold due to a dead point in rotation.

[0019] 3. A spring is provided to assist in the retraction of the telescopic stop bar, which ensures that the inner rod is always subjected to an elastic force that slides into the inner cavity of the sleeve rod. This allows the telescopic stop bar to retract automatically without relying on the push force of the trolley, ensuring that the telescopic stop bar retracts stably and without jamming.

[0020] Furthermore, due to the spring force, when the trolley is returning, the telescopic lever will remain horizontal under the action of the spring force until it is fully retracted. Only then will the telescopic lever fold downwards. This makes the retraction and folding of the two telescopic levers a continuous and progressive working state. Compared to the retraction of the telescopic lever during the folding process, no additional shear force will be generated on the telescopic lever during the retraction process, further preventing jamming during the retraction of the telescopic lever.

[0021] Meanwhile, the continuous and progressive working state of the telescopic barrier's retraction and folding also allows the telescopic barrier to remain in a horizontal state for a longer period of time during the trolley's return process, resulting in a better enclosure effect.

[0022] 4. Two start buttons are provided. Compared with a single start button, the trolley can only be started by pressing both start buttons at the same time, which avoids accidental activation of the trolley and the occurrence of safety accidents.

[0023] 5. A light grating sensor is installed to detect whether a person or foreign object is passing through the partition cavity. When a person climbs over the telescopic barrier to enter the partition cavity, a signal is sent to the control console, which controls the switch relay to disconnect. At this time, the trolley stops running, further improving the safety of the device.

[0024] 6. By placing the relay reset button and control console at both ends of the compartment, staff are required to inspect both ends of the compartment in case of a potential safety accident and eliminate the hazard before restarting the switch relay, thus enhancing the staff's safety awareness.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] For ease of understanding, the specific structure and working method of this utility model are further described below with reference to the accompanying drawings:

[0031] The specific structure of this utility model is as follows: Figure 1-3 As shown, its main structure includes a vacuum chamber 10, a track 51 fixed to one side of the vacuum chamber 10, and a trolley 50 sliding on the track 51. A partition cavity is formed between the adjacent ends of the vacuum chamber 10 and the trolley 50. Both ends of this partition cavity are equipped with blocking elements to prevent personnel from entering the partition cavity from either end. Specifically, the blocking elements include two telescopic rods 60 whose adjacent ends are hinged to each other via a horizontal pivot. The opposite ends of the two telescopic rods 60 are hinged to the vacuum chamber 10 and the trolley 50 respectively via horizontal hinge seats. The two horizontal hinge seats are at the same height, and the axis of the horizontal pivot and the hinge axis of the horizontal hinge seats are both perpendicular to the length direction of the track 51. Before the trolley 50 departs, the two telescopic baffles 60 retract and form a V-shape. As the trolley 50 slides outward, the two telescopic baffles 60 gradually rotate into a horizontal straight structure. Then, the two telescopic baffles 60 extend outward, forming a barrier structure at both ends of the partition cavity, effectively reducing safety hazards during the operation of the trolley 50. When the trolley 50 slides back inward, the telescopic baffles 60 retract, and their adjacent hinged ends move downward under gravity, eventually forming the initial V-shape as the trolley 50 gradually returns to its original position. This barrier structure formed by the two telescopic baffles 60 is not only simple in structure but also automatically folds and retracts, preventing personnel from entering from both ends of the partition cavity without affecting the normal operation of the trolley 50.

[0032] Furthermore, such as Figure 2As shown, the adjacent ends of the telescopic stop bar 60 are bent downwards in an arc shape, so that the horizontal pivot at the adjacent ends of the telescopic stop bar 60 is located below the axis of the telescopic stop bar 60. This allows the telescopic stop bar 60 to fold downwards more stably during retraction because the horizontal pivot is located below the axis of the telescopic stop bar 60, preventing the telescopic stop bar 60 from failing to fold due to a dead point in rotation.

[0033] Based on the above, such as Figure 2 As shown, the telescopic stop lever 60 includes a sleeve lever 61 and an inner rod 62 that slides coaxially inside the sleeve lever 61. A spring 63 is provided on the sleeve lever 61 to elastically drive the inner rod 62 to slide inwards towards the inside of the sleeve lever 61. In actual implementation, the spring 63 can be a tension spring located at the bottom end of the inner cavity of the sleeve lever 61, with its two ends connected to the bottom of the sleeve lever 61 and the bottom of the inner rod 62, respectively. Alternatively, the spring 63 can be a compression spring sleeved on the inner rod 62. Specifically, there is a gap between the inner cavity of the sleeve lever 61 and the outer wall of the inner rod 62; the end of the sleeve lever 61 and the inner rod 62 form a sliding fit; and a stop block is fixed to the end of the inner rod 62 located within the inner cavity of the sleeve lever 61. The compression spring is sleeved on the rod body of the inner rod 62 located within the inner cavity of the sleeve lever 61. The arrangement of the springs 63 ensures that the inner rod 62 is always subjected to an elastic force that slides into the inner cavity of the sleeve rod 61. This allows the telescopic stop rod 60 to retract automatically without relying on the pushing force of the trolley 50, ensuring that the telescopic stop rod 60 retracts stably and without jamming. Furthermore, due to the elastic force of the springs 63, when the trolley 50 is returning, the telescopic stop rod 60 will remain horizontal under the action of the springs 63 until it is fully retracted, at which point it will fold downwards. This makes the retraction and folding of the two telescopic stop rods 60 a continuous and progressive process. Compared to the retraction during the folding process, this retraction process does not generate additional shear force on the telescopic stop rod 60, further preventing jamming during retraction. Simultaneously, the continuous and progressive retraction and folding of the telescopic stop rod 60 also allows it to maintain a horizontal state for a longer period during the trolley 50's return process, resulting in a better containment effect.

[0034] Based on the above, such as Figure 1 As shown, a control console 20 is provided on the side of the vacuum chamber 10. The control console 20 has two start buttons 21 for starting the trolley 50, and the trolley 50 is started by pressing both start buttons 21 simultaneously. Compared with a single start button 21, the method of starting the trolley 50 by pressing both start buttons 21 simultaneously avoids the accidental activation of the trolley 50 by pressing the start button 21, which could lead to a safety accident.

[0035] Furthermore, the distance between the two start buttons 21 is 25cm-30cm, so that the start buttons 21 must be pressed with both hands, further preventing the two start buttons 21 from being accidentally pressed at the same time.

[0036] Based on the above, such as Figure 1 and Figure 3 As shown, grating sensors 40 with output terminals connected to the control console 20 are installed at both ends of the partition cavity. A switch relay for disconnecting the control circuit is installed on the control console 20. The grating sensors 40 are used to detect whether a person or foreign object passes through the partition cavity. When a person climbs over the telescopic barrier 60 to enter the partition cavity, a signal is sent to the control console 20, which then controls the switch relay to disconnect. At this time, the trolley 50 stops running, further improving the safety of the device.

[0037] Furthermore, it also includes a relay reset button 70 for restarting the control switch relay. The relay reset button 70 and the control console 20 are respectively arranged at both ends of the compartment, so that the operator of the control console 20 must cross to the other end of the compartment to trigger the relay reset button 70. By using the layout of the relay reset button 70 and the control console 20 at both ends of the compartment, the operator is prompted to inspect both ends of the compartment in the event of a potential safety accident, and only restart the switch relay after eliminating the potential hazard, thus helping to enhance the operator's safety awareness.

[0038] Furthermore, such as Figure 1 As shown, a buzzer 30 with an input terminal connected to the control console 20 is installed on the vacuum chamber 10. After receiving information from the grating sensor 40 that someone has entered the partition chamber, the control console 20 controls the buzzer 30 to sound an alarm, which is used to alert staff and personnel entering the partition chamber.

[0039] Furthermore, such as Figure 3 As shown, the buzzers 30 are set in two groups and are respectively arranged at both ends of the partition cavity to ensure that the personnel at both ends of the partition cavity can hear the alarm of the buzzers 30.

[0040] Of course, those skilled in the art will recognize that this invention is not limited to the details of the exemplary embodiments described above, but also includes the same or similar structures that can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
