Description

Technical Field

[0001] The present application relates to the technical field of plastic bag production equipment, and in particular to a plastic bag hot-pressing sealing device. Background Art

[0002] Plastic bags are bags made of plastic as the main raw material. They are indispensable items in people's daily lives and are often used to hold other items. As people pay more attention to the environment, environmentally friendly plastic bags have emerged. Environmentally friendly plastic bags are the abbreviation of various biodegradable plastic bags. Traditional degradable plastic bags are generally sealed by hot-pressing sealing.

[0003] Chinese patent "CN221189399U" discloses "a hot pressing sealing device for degradable plastic bags", which achieves heat dissipation of the hot pressing touch plate by arranging a heat dissipation sticker on the slide rail, thereby avoiding the problem of affecting the components in the equipment due to excessive temperature; however, further analysis shows that the touch plate is always in contact with the slide rail regardless of whether it is in the hot pressing process or in the non-working state, and the heat dissipation sticker is in a state of heat dissipation all the time. Although the cooling problem is solved, it is understandable that cooling can be omitted in the working state, and cooling in the non-working state can effectively save energy. Therefore, this method still has the problem of high energy consumption. Utility Model Content

[0004] The purpose of the present application is to provide a plastic bag hot-pressing sealing device to solve at least one of the above-mentioned technical problems.

[0005] In order to solve the above technical problems, the present application provides a plastic bag hot-pressing sealing device, comprising a workbench and a gantry, wherein the gantry is mounted on the workbench;

[0008] A sliding assembly and a linkage assembly, the heat dissipation assembly is connected to the sliding assembly, the sliding assembly is slidably arranged on the workbench, and the linkage assembly is connected to the lifting drive assembly and the sliding assembly;

[0009] Wherein, when the lifting drive component drives the hot pressing mechanism to lift in the vertical direction, it is suitable for driving the two heat dissipation components to move closer to or away from each other through the linkage component;

[0010] When the heat dissipation component is close to the heat pressing mechanism, it is suitable for dissipating heat for the heat pressing mechanism;

[0011] In the above implementation process, the staff places the plastic bag to be sealed under the hot pressing mechanism, or cooperates with some material feeding mechanisms to feed the plastic bag under the hot pressing mechanism, and then drives the hot pressing mechanism downward through the lifting drive assembly to act on the plastic bag to achieve sealing; in the process of the lifting drive assembly driving the hot pressing mechanism to press down, it also drives the sliding assembly to move through the linkage assembly, which can be further understood as making the two sets of relative sliding assemblies move away from each other, and the heat dissipation assembly is connected to the sliding assembly, so when the sliding assemblies move away from each other, the heat dissipation assemblies also move away from each other synchronously, and after the hot pressing sealing is completed, the lifting drive assembly drives The hot pressing mechanism rises and resets, and at this time the sliding components move in the opposite direction of the original moving away direction, that is, they move closer to each other and approach the hot pressing mechanism, and finally achieve heat dissipation of the hot pressing mechanism by approaching the hot pressing mechanism; this solution uses an movably arranged heat dissipation component to cooperate with a linkage component to switch different working states when the hot pressing mechanism is in a hot pressing state and a stationary state, so as to achieve no heat dissipation and cooling during the hot pressing process, and the heat dissipation components will only move closer to achieve cooling and heat dissipation after the hot pressing is completed. This not only can achieve targeted heat dissipation and avoid damage caused by overheating of the machine, but also effectively avoid excessive energy consumption, and effectively save energy to a certain extent.

[0012] Preferably, the hot pressing mechanism comprises a hot pressing touch plate and a heating component, wherein the heating component is used to heat the hot pressing touch plate, and the hot pressing touch plate is suitable for being used on a plastic bag;

[0013] In the above implementation process, the heating component can heat the heat-pressing touch plate to increase the temperature of the heating touch plate, which can eventually act on the plastic bag to achieve heat-pressing sealing.

[0014] Preferably, the heat dissipation assembly comprises a heat dissipation plate formed with a U-shaped groove, and the thermal pressure contact plate is suitable for extending into the U-shaped groove of the heat dissipation plate;

[0015] In the above implementation process, the side of the thermal pressure touch plate can extend into the U-shaped groove of the heat sink, and the heat of the thermal pressure touch plate can be transferred to the heat sink to reduce the temperature of the thermal pressure touch plate itself, thereby achieving heat dissipation and cooling.

[0016] Preferably, a plurality of heat dissipation fins are provided on the outer wall of the heat dissipation plate;

[0017] In the above implementation process, the present solution further arranges a plurality of heat dissipation fins on the outer wall of the heat dissipation plate, which can effectively increase the heat dissipation area and thus improve the heat dissipation efficiency.

[0018] Preferably, the sliding assembly includes a sliding rail and a sliding block slidably disposed on the sliding rail.

[0019] Preferably, the lifting drive assembly includes a lifting drive member and a drive rod connected to the lifting drive member.

[0020] Preferably, the linkage assembly comprises a guide plate connected to the driving rod, and a guide groove is provided on the guide plate;

[0021] A limit block adapted to the guide groove is provided on the sliding block, and the limit block is suitable for extending into the guide groove;

[0022] When the lifting driving member drives the thermal pressure contact plate to lift, it is suitable for driving the sliding block to approach or move away from the thermal pressure contact plate through the guide plate;

[0023] In the above implementation process, when the lifting drive member drives the driving rod to descend, it will drive the thermal pressure touch plate to descend, and also drive the guide plate to descend. The limit block on the sliding block slides with the guide groove in the guide plate, so it will drive the limit block to move along the guide groove, and finally drive the sliding block to move horizontally, so as to realize the heat dissipation components moving away from each other; otherwise, they will move closer to each other.

[0024] Preferably, the linkage assembly comprises a wedge block connected to the drive rod and a guide block connected to the sliding block;

[0025] Also includes an elastic member suitable for driving the sliding block to reset to be close to the thermal pressure touch plate;

[0027] When the lifting driving member drives the thermal pressure contact plate to lift, it is suitable for driving the sliding block away from the thermal pressure contact plate through the wedge block;

[0028] In the above implementation process, the present scheme provides another implementation method of the linkage component. When the lifting drive member drives the driving rod to move downward, it drives the thermal pressure touch plate to move downward, and also drives the wedge block to move downward synchronously. When the wedge block moves downward, it will prompt the guide block to move away from the thermal pressure touch plate to drive the sliding block to move along the side away from the thermal pressure touch plate, and finally make the heat dissipation component move away from the thermal pressure touch plate. In this process, it also prompts the elastic member to store elastic potential energy. When the lifting drive drives the driving rod to rise, under the slope cooperation of the wedge block and the guide block and the elastic force of the elastic member, the sliding blocks move closer to each other, and finally the heat dissipation component can be close to the thermal pressure touch plate to dissipate heat from the thermal pressure touch plate.

[0029] Compared with the prior art, the beneficial effect of the present application is that: the present solution switches between different working states when the hot pressing mechanism is in the hot pressing state and the static state through the movable heat dissipation component cooperating with the linkage component, so as to achieve no heat dissipation and cooling during the hot pressing process, and the heat dissipation components will only be brought together to achieve cooling and heat dissipation after the hot pressing is completed. In this way, not only can the heat dissipation be achieved in a targeted manner to avoid damage caused by overheating of the machine, but also the excessive energy consumption can be effectively avoided, and energy can be effectively saved to a certain extent.

[0040] Example

[0041] Plastic bags are bags made of plastic as the main raw material. They are indispensable items in people's daily lives and are often used to hold other items. As people pay more attention to the environment, environmentally friendly plastic bags have been born. Environmentally friendly plastic bags are the abbreviation of various types of biodegradable plastic bags. Traditional degradable plastic bags are generally sealed by hot pressing sealing. Chinese patent "CN221189399U" discloses "a hot pressing sealing device for degradable plastic bags", which achieves heat dissipation of the hot pressing touch plate by setting a heat dissipation sticker on the slide rail, thereby avoiding the problem of affecting the components in the equipment due to excessive temperature; however, further analysis shows that the touch plate is always in contact with the slide rail whether in the hot pressing process or in the non-working state, and the heat dissipation sticker is in a state of heat dissipation all the time. Although the cooling problem is solved, it is understandable that cooling can be omitted in the working state, and cooling in the non-working state can effectively save energy. Therefore, this method still has the problem of relatively high energy consumption; in order to solve the above technical problems, this embodiment provides the following technical solutions:

[0042] For details, see Figure 1-4 , this embodiment provides a plastic bag hot-pressing sealing device, including a workbench 10, a gantry 11, a lifting drive assembly, a hot-pressing mechanism, a heat dissipation assembly, a sliding assembly and a linkage assembly;

[0043] Specifically, the gantry 11 is arranged on the workbench 10;

[0044] Specifically, the lifting drive assembly is arranged on the gantry 11, and its driving end is connected to the hot pressing mechanism, and the lifting drive assembly is used to drive the hot pressing mechanism to lift;

[0045] Specifically, two groups of heat dissipation components are provided and are respectively arranged on two opposite sides of the heat pressing mechanism;

[0046] Specifically, the heat dissipation assembly is connected to the sliding assembly, and it can be understood that the sliding assembly is also provided with two groups;

[0047] Further, the sliding assembly is slidably disposed on the workbench 10, and the linkage assembly connects the lifting drive assembly and the sliding assembly;

[0048] When the lifting drive assembly drives the hot pressing mechanism to lift in the vertical direction, it is suitable for driving the two heat dissipation assemblies to move closer to or away from each other through the linkage assembly;

[0049] Specifically, the heat dissipation component is suitable for dissipating heat to the heat pressing mechanism when it is close to the heat pressing mechanism;

[0050] In the above scheme, the staff places the plastic bag to be sealed under the hot pressing mechanism, or cooperates with some material feeding mechanisms to feed the plastic bag under the hot pressing mechanism, and then drives the hot pressing mechanism downward through the lifting drive component to act on the plastic bag to achieve sealing; in the process of the lifting drive component driving the hot pressing mechanism to press down, it also drives the sliding component to move through the linkage component, which can be further understood as making the two sets of relative sliding components move away from each other, and the heat dissipation component is connected to the sliding component, so when the sliding components move away from each other, the heat dissipation components also move away from each other synchronously, and after completing the hot pressing sealing, the lifting drive component drives the hot pressing mechanism to move downward. The mechanism rises and resets, and at this time the sliding components move in the opposite direction of the original moving away direction, that is, they move closer to each other and closer to the hot pressing mechanism, and finally achieve heat dissipation of the hot pressing mechanism by approaching the hot pressing mechanism; this solution uses an movably arranged heat dissipation component to cooperate with a linkage component to switch different working states when the hot pressing mechanism is in a hot pressing state and a stationary state, so as to achieve no heat dissipation and cooling during the hot pressing process, and the heat dissipation components will only move closer to achieve cooling and heat dissipation after the hot pressing is completed. This not only can achieve targeted heat dissipation and avoid damage caused by overheating of the machine, but also effectively avoid excessive energy consumption, and effectively save energy to a certain extent.

[0051] Specifically, the hot pressing mechanism includes a hot pressing touch plate 40 and a heating component (not shown in the figure), the heating component is used to heat the hot pressing touch plate 40, and the hot pressing touch plate 40 is suitable for being used on the plastic bag;

[0052] In the above solution, the heating component can heat the heat-pressing touch plate 40 to increase the temperature of the heating touch plate, which can eventually act on the plastic bag to achieve heat-pressing sealing.

[0053] It should be noted that the heating component cooperates with the thermal pressure touch plate 40 to achieve heating of the thermal pressure touch plate 40, which is a relatively mature technology in the prior art. Therefore, the specific structure and working principle of the heating component are not further described in this solution.

[0054] Specifically, the heat dissipation assembly includes a heat dissipation plate 52 formed with a U-shaped groove, and the thermal pressure contact plate 40 is suitable for extending into the U-shaped groove of the heat dissipation plate 52;

[0055] In the above solution, the side of the thermal pressure touch plate 40 can extend into the U-shaped groove of the heat dissipation plate 52, and the heat of the thermal pressure touch plate 40 can be transferred to the heat dissipation plate 52 to reduce the temperature of the thermal pressure touch plate 40 itself, thereby achieving heat dissipation and cooling.

[0056] It is further understandable that the heat sink 52 is made of a heat-conducting metal material.

[0057] Furthermore, a plurality of heat dissipation fins are provided on the outer wall of the heat dissipation plate 52;

[0058] In the above solution, this solution further provides a plurality of heat dissipation fins on the outer wall of the heat dissipation plate 52, which can effectively increase the heat dissipation area and thus improve the heat dissipation efficiency.

[0059] For details, see Figure 1-2 The sliding assembly includes a sliding rail 12 and a sliding block 51 slidably disposed on the sliding rail 12 .

[0060] Specifically, the lifting drive assembly includes a lifting drive member 21 and a drive rod 22 connected to the lifting drive member 21 .

[0061] In one embodiment, the lifting drive member 21 may be a lifting drive cylinder or a lifting drive motor.

[0062] For details, see Figure 2 In one embodiment, the linkage assembly includes a guide plate 30 connected to the driving rod 22, and a guide groove 31 is provided on the guide plate 30;

[0063] Furthermore, a limit block 53 adapted to the guide groove 31 is provided on the sliding block 51, and the limit block 53 is suitable for extending into the guide groove 31;

[0064] When the lifting driving member 21 drives the thermal pressure contact plate 40 to lift, it is suitable for driving the sliding block 51 to approach or move away from the thermal pressure contact plate 40 through the guide plate 30;

[0065] In the above scheme, when the lifting drive member 21 drives the driving rod 22 to descend, it will drive the thermal pressure touch plate 40 to descend, and also drive the guide plate 30 to descend. The limit block 53 on the sliding block 51 slides with the guide groove 31 in the guide plate 30, so it will drive the limit block 53 to move along the guide groove 31, and finally drive the sliding block 51 to move horizontally, so as to realize the heat dissipation components moving away from each other; otherwise, they will move closer to each other.

[0066] In another embodiment, see Figure 4, the linkage assembly includes a wedge block 61 connected to the driving rod 22 and a guide block 62 connected to the sliding block 51;

[0067] Furthermore, it also includes an elastic member 54 adapted to drive the sliding block 51 to reset to be close to the thermal pressure contact plate 40;

[0068] Specifically, a guide slope is formed on the guide block 62 to match the slope of the wedge block 61;

[0069] When the lifting driving member 21 drives the thermal pressure contact plate 40 to lift, it is suitable for driving the sliding block 51 away from the thermal pressure contact plate 40 through the wedge block 61;

[0070] In the above scheme, this scheme provides another implementation method of the linkage component. When the lifting drive member 21 drives the driving rod 22 to move downward, it drives the thermal pressure touch plate 40 to move downward, and also drives the wedge block 61 to move downward synchronously. When the wedge block 61 moves downward, it will prompt the guide block 62 to move away from the thermal pressure touch plate 40 to drive the sliding block 51 to move along the side away from the thermal pressure touch plate 40, and finally make the heat dissipation component away from the thermal pressure touch plate 40. In this process, it also prompts the elastic member 54 to store elastic potential energy. When the lifting drive drives the driving rod 22 to rise, under the slope cooperation of the wedge block 61 and the guide block 62 and the elastic force of the elastic member 54, the sliding blocks 51 move closer to each other, and finally the heat dissipation component can be close to the thermal pressure touch plate 40 to dissipate heat from the thermal pressure touch plate 40.

[0071] In one embodiment, the elastic member 54 may be a spring.

[0072] For details, see Figure 3 In one embodiment, it also includes a guide rail 13 arranged on the gantry 11, and the guide rail 13 can be slidably matched with the guide plate 30 or the driving rod 22, thereby making the overall lifting action more stable.

[0073] Specifically, in one embodiment, a pad 41 is provided on the workbench 10, and the pad 41 is provided below the hot pressing mechanism for supporting the plastic bag. The pad 41 can make the hot pressing surface smoother, and can be replaced after a period of use to ensure its long-term smoothness. Compared with the method of hot pressing directly on the workbench 10, it is more conducive to later maintenance.

[0074] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application are within the scope of the technical solution of the present application.
