Simultaneously, a spray mechanism is activated during this upward rotation, rinsing the contact surfaces between the upper ends of the two gates and the lower end of the label discharge tube. This prevents label residue from affecting the seal of the discharge port and effectively blocks heat loss from the high-temperature alkaline tank discharge port of the bottle washing machine, thereby reducing costs.

It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The same reference numerals used throughout the drawings indicate the same or similar parts.
[0019] It should be noted that, unless otherwise specified, when a feature is referred to as "fixed" or "connected" to another feature, it can be directly fixed or connected to the other feature, or indirectly fixed or connected to the other feature. Furthermore, the descriptions of "upper," "lower," "left," and "right" used in this utility model are only relative to the relative positional relationships of the various components of this utility model in the accompanying drawings.
[0020] Reference Figure 1 and Figure 2 A device for reducing heat dissipation from the label discharge port of a high-temperature alkaline tank in a bottle washing machine includes a first gate 5, a second gate 6, a drive mechanism 2, and a spraying mechanism. A label discharge cylinder 1 is installed outside the alkaline tank. The drive mechanism is located outside the label discharge cylinder 1. The drive mechanism 2 includes a drive component, a first pull rod 22, and a second pull rod 23. The drive component is fixed to the outer wall of the high-temperature alkaline tank of the bottle washing machine. The upper end of the first pull rod 22 is connected to the drive component, and the lower end is hinged to the first gate 5 with the hinge axis horizontally positioned. The upper end of the second pull rod 23 is connected to the drive component, and the lower end is hinged to the second gate 6 with the hinge axis horizontally positioned. The drive component is used to drive the first pull rod 22 and the second pull rod 23 to move synchronously upwards or downwards. The first gate 5 and the second gate 6 are installed at the label discharge port 11 of the high-temperature alkaline tank of the bottle washing machine to control the discharge of labels and to block heat.
[0021] The label discharge cylinder 1 of the bottle washing machine is vertically arranged and has a label discharge port 11 at the lower end. The ends of the first gate plate 5 and the second gate plate 6 that are far apart from each other are hinged to the label discharge cylinder of the bottle washing machine and the hinge shaft is set horizontally. The first gate plate 5 and the second gate plate 6 together block or open the label discharge port 11. The water outlet of the spraying mechanism is provided with a first water outlet and a second water outlet. The first water outlet sprays water toward the first gate plate 5 and the second water outlet sprays water toward the second gate plate 6. When the first gate plate 5 and the second gate plate 6 rotate upward to close the discharge port 11, they can jointly block the discharge port 11 at the lower end of the discharge cylinder. The length of the first gate plate 5 and the second gate plate 6 in the direction parallel to the hinge axis is greater than the length of the discharge port 11 in this direction. That is, the first gate plate 5 and the second gate plate 6 both protrude out of the discharge port 11 in the horizontal direction. The first gate plate 5 has a first end extending out of the discharge port 11 at the end near the first pull rod 22. The first pull rod 22 is hinged to the first end. This hinge node is located outside the discharge port 11 and on the side of the centerline of the first gate plate 5 near the second gate plate. The second gate plate 6 has a second end extending out of the discharge port 11 at the end near the second pull rod 23. The second pull rod 23 is hinged to the second end. This hinge node is located outside the discharge port 11 and on the side of the centerline of the second gate plate 6 near the first gate plate.
[0022] This solution includes a device for reducing heat loss from the label discharge port 11 of the high-temperature alkaline tank in the bottle washing machine. A first gate 5 and a second gate 6 are installed at the discharge port 11. The opening and closing of the first gate 5 and the second gate 6 releases the labels accumulated in the label discharge cylinder 1. When a certain amount of labels accumulates, the ends of the first gate 5 and the second gate 6 that are close to each other rotate downwards to open the discharge port 11 and discharge the labels. After the labels are discharged, the ends of the first gate 5 and the second gate 6 that are close to each other rotate upwards to close the discharge port 11. During the upward rotation of the two gates, a spray mechanism 7 is simultaneously activated, rinsing the contact surfaces between the upper ends of the two gates and the lower ends of the label discharge cylinder 1. This prevents label residue from affecting the seal of the first gate 5 and the second gate 6 on the discharge port 11, effectively preventing heat loss from the high-temperature alkaline tank discharge port 11 of the bottle washing machine, thereby reducing costs.
[0023] Specifically, the lower end of the driving component is connected to a lifting rod, which drives the lifting rod to rise or fall. The upper end of the first pull rod 22 is hinged to the lower end of the lifting rod, and the upper end of the second pull rod 23 is hinged to the lower end of the lifting rod. The driving component is a cylinder 21, and the lifting rod is a piston rod 211. The two gates are driven by the cylinder 21. The lower end of the piston rod 211 of the cylinder 21 is bolted to the first pull rod 22 and the second pull rod 23. The threaded portion of the bolt forms a hinge axis. A single bolt passes horizontally and synchronously through the ends of the first pull rod, the second pull rod, and the piston rod, and is connected to the bolt by a nut. The lower ends of the first pull rod 22 and the second pull rod 23 can be fixed to the corresponding gates with bolts. The threaded portion of the bolt forms a hinge axis, ensuring smooth up-and-down rotation of each gate. The connection structure between the first gate 5, the second gate 6, and the driving mechanism 2 on the outside of the label cylinder 1 is as described above. Figure 1 As shown.
[0024] Specifically, the device in this solution for reducing heat dissipation from the high-temperature alkali tank discharge port of the bottle washing machine also includes a gate guide rail. The gate guide rail is installed on both sides of the discharge port 11. The first pull rod 22, the second pull rod 23, the first gate 5, and the second gate 6 are all located within the gate guide rail, which can restrict the relative movement of the two gates along their rotation axis, ensuring the vertical movement of the gates and preventing skewness and jamming. In addition, the base on the cylinder 21 is fixed to the outer wall of the alkali tank with high-strength bolts to ensure stability.
[0025] Specifically, the spraying mechanism 7 is provided with a water inlet, which is connected to a recycled water system. Using recycled water for spraying can reduce costs and is more environmentally friendly.
[0026] Specifically, the spraying mechanism 7 includes a first water path, a second water path, a first spray pipe 71, and a second spray pipe. The first spray pipe 71 is detachably installed at the end of the first gate 5 away from the second gate 6 and located above the first gate 5. The second spray pipe is detachably installed at the end of the second gate 6 away from the first gate 5 and located above the second gate 6. One end of the first spray pipe 71 is connected to the recycled water system through the first water path, and the other end is provided with a plurality of first spray nozzles to form the first water outlet. One end of the second spray pipe is connected to the recycled water system through the second water path, and the other end is provided with a plurality of second spray nozzles to form the second water outlet.
[0027] This design connects the piston rod 211 of cylinder 21 to the lower gate. When the piston pushes down, both gates open simultaneously, and after the label falls, the spray pipe is activated to clean the gates. When the piston lifts up, both gates lift and close the label discharge port 11. By adding a gate-type structure to the label discharge port 11 to form a valve, the gate can be opened periodically to discharge the washed label accumulated in the label discharge port 11, preventing the alkali tank from being directly exposed to the atmosphere and causing a large amount of heat to be dissipated.
[0028] Specifically, the spray direction 73 of the first spray nozzle is towards the contact surface between the first gate 5 and the discharge port 11, and the spray direction 73 of the second spray nozzle is towards the contact surface between the second gate 6 and the discharge port 11. Both the first and second water paths can be formed by equal pipes. The first spray pipe 71 and the second spray pipe are both connected to the water pipe through flanges and connected to an external high-pressure water source. The spray nozzles are fan-shaped nozzles to ensure a large washing coverage area.
[0029] Specifically, the device for reducing heat dissipation from the high-temperature alkali tank discharge port of the bottle washing machine in this solution also includes a mounting bracket for fixing the first spray pipe 71 and the second spray pipe. A water pipe can be used to pass through the side wall of the discharge cylinder and connect to the spray pipe 71. The mounting bracket is installed on the side wall inside the discharge cylinder 1, and the two spray pipes are fixed on the mounting bracket. The mounting bracket can be equipped with clamps for fixing the spray pipes. The first spray pipe 71 and the second spray pipe are detachably connected to the lower end of the discharge cylinder 1 through clamps, which facilitates disassembly and cleaning. The mounting bracket for the spray pipes is welded to the side wall inside the discharge cylinder 1 to ensure that the spray pipes are stable and do not shake. The length direction of the spray pipes can be parallel to the hinge axis of the gate, and the two spray pipes are located above the ends of the two gates that are far apart from each other.
[0030] Specifically, the device for reducing heat dissipation from the high-temperature alkali tank drain outlet of the bottle washing machine in this solution also includes a PLC controller. The PLC controller is installed inside the bottle washing machine's electrical cabinet and can use a conventional chip. A first solenoid valve 72 is installed on the first spray pipe 71, located between the first outlet and the first water path; a second solenoid valve is installed on the second spray pipe, located between the second outlet and the second water path; during the upward rotation and closing of the first gate 5 and the second gate 6, the PLC controller controls the first solenoid valve 72 and the second solenoid valve to open.
[0031] Specifically, the device for reducing heat dissipation at the high-temperature alkali tank discharge port of the bottle washing machine in this solution also includes a first switch 3, a second switch 4, and a sensor switch. The sensor switch is installed inside the discharge cylinder 1. The sensor switch is used to detect the amount of label paper accumulation and control the cylinder 21 to start, thereby opening the first gate 5 and the second gate 6. The first switch 3 and the second switch 4 are installed at intervals from top to bottom on the outside of the cylinder 21. Both the first switch 3 and the second switch 4 are magnetic switches. The first switch 3 is used to detect the height of the label paper stacking inside the discharge cylinder 1. When the stack reaches the position of the first switch 3, the gate opens to discharge the label paper. When the label paper is discharged to the position of the second switch 4, the spray is started to spray.
[0032] Specifically, one end of the first gate plate 5 and the second gate plate 6 are connected to the label discharge cylinder 1 of the bottle washing machine via a gate plate guide rail. That is, a first pull rod 22 and a second pull rod 23 are respectively installed on one end of the first gate plate 5 and the second gate plate 6. The upper ends of the first pull rod 22 and the second pull rod 23 pass through the gate plate guide rail and are connected to the piston rod 211, while the cylinder 21 is installed on the outside of the label discharge cylinder 1. The gate plate guide rail includes a first connecting plate and a second connecting plate arranged symmetrically. The upper ends of the first connecting plate and the second connecting plate are connected to the outside of the label discharge cylinder 1. The first connecting plate and the second connecting plate are arranged symmetrically in a figure-eight shape or are both vertical and parallel to each other. There is a vertical gap between the upper ends of the first connecting plate and the outer wall of the label discharge cylinder. The piston rod 211, the first pull rod 22, and the second pull rod 23 can pass through the gap between the first connecting plate and the outer wall of the label discharge cylinder.
[0033] The first connecting plate and the labeling cylinder 1 can be connected by at least two spaced connecting blocks. The two ends of the connecting blocks in the horizontal direction are connected to the outer sides of the first connecting plate and the labeling cylinder 1, respectively. The piston rod 211, the first pull rod 22, and the second pull rod 23 can pass through the gap between the two connecting blocks. The connection method between the connecting blocks and the outer sides of the first connecting plate and the labeling cylinder 1 can be welding or other fixed connection methods, or a common detachable fixed connection method can be selected. The connection method between the second connecting plate and the labeling cylinder 1 can refer to the connection method between the first connecting plate and the labeling cylinder 1. The first gate plate 5 and the second gate plate 6 are both located between the first and second connecting plates. The first and second connecting plates can restrict the relative movement of the two gate plates along their rotation axes, ensuring vertical movement of the gate plates and preventing skew and jamming. In addition, the base on the cylinder 21 is fixed to the outer wall of the alkali tank with high-strength bolts to ensure stability.
[0034] In another embodiment, the first gate 5 includes a first plate, a second plate, and a third plate connected in a U-shape in sequence. The second gate 6 has the same structure as the first gate 5 and is symmetrically arranged. The first pull rod 22 and the second pull rod 23 are respectively hinged to the two first plates. The outer sides of the two first plates are provided with hinged connecting shafts. The ends of the first pull rod 22 and the second pull rod 23 are respectively rotatably fitted onto the two hinged connecting shafts. In actual application, the connection structure between the two third plates and the label cylinder 1 can adopt the same or similar connection structure as the first plates. The third plates and the label cylinder 1 may not be provided with connecting components such as pull rods. The ends of the two second plates that are far apart from each other are respectively hinged to the label cylinder 1. The hinged connection structure can adopt a conventional hinged structure. The width of the second plate is greater than the width of the label opening. When the two gates are rotated upward, the two second plates can block the label opening. The first plate and the third plate are respectively located on both sides of the label opening 11 or the label cylinder 1. The spraying mechanism 7 sprays water onto the two second plates, and water flows out from the end of the two second plates that are close to each other. The arrangement of the first plate and the third plate can also prevent water from flowing out from both sides of the second plates.
[0035] Specifically, the device for reducing heat dissipation at the high-temperature alkali tank discharge port of the bottle washing machine in this solution also includes an emergency switch. The gate can be manually operated to open and close in case of automatic system failure. The emergency switch is connected to an appropriate location outside the equipment, such as on the equipment support column. The emergency switch is used to open the first gate 5 and the second gate 6. That is, in case of emergency, the knob on the emergency switch can be manually opened to open the two gates under the discharge cylinder 1 for discharge. The relevant circuit connection method of the emergency switch can be implemented by conventional circuit connection method.
[0036] This device, used to reduce heat dissipation from the high-temperature alkali tank discharge port of a bottle washing machine, operates as follows: During use, when the sensor detects that the label storage cylinder has reached a set amount of label paper, it sends a signal to the PLC controller. The PLC controller then controls the solenoid valve to vent, causing cylinder 21 to push down and two gates to rotate downwards, opening the discharge port 11. The set amount can be 60% of the capacity of the discharge cylinder 1. After the label paper is discharged, the PLC controller controls cylinder 21 to lift the two gates, which then rotate upwards synchronously to close the discharge port 11. A delay of 5-10 seconds can be allowed after the label paper is discharged before the cylinder 21 is lifted again. During the upward rotation of the gates to close, the spray mechanism 7 is triggered to spray water. Specifically, the PLC controller controls the solenoid valves on each spray pipe to open, allowing high-pressure water from the spray nozzles to flush the gate contact surfaces, preventing label paper residue from affecting the seal. The spray duration can be set to 3-5 seconds to ensure thorough rinsing without excessive water waste. The inlet of the spray mechanism 7 can be connected to the overflow water from the bottle washing machine, and the overflow water from the bottle washing machine can be used as spray water.
[0037] This solution employs a gate-type structure forming a valve at the discharge port 11, combined with a spray mechanism 7, to achieve both discharge and sealing functions. Based on PLC intelligent control, it integrates automatic discharge, spray rinsing, and heat sealing. The inductive switch and time-delay control methods optimize discharge efficiency and reduce manual intervention. By periodically closing the gate, heat loss from the high-temperature alkali tank is reduced, lowering energy consumption and achieving energy-saving effects.
[0038] Other aspects of the device for reducing heat dissipation from the high-temperature alkali tank drain outlet of a bottle washing machine described in this utility model are found in the prior art and will not be repeated here.
[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
