Description

Technical Field

[0001] The present invention relates to the technical field of automatic waste packing, and particularly to a method for realizing automatic packing of waste equipment.

Background Art

[0002] In the prior art's automatic waste packing method, during the heat sealing and hot cutting of garbage bags, overheating easily occurs, resulting in the garbage bags sticking to the heating components, causing the receiving section of the garbage bags that should fall off to not fall normally, and seriously affecting the subsequent heat sealing and hot cutting, resulting in abnormal subsequent heat sealing and hot cutting functions, and even damaging the equipment, requiring manual handling and cleaning; during the heat sealing and hot cutting process, due to the downward force generated by the garbage bags and the waste inside them under the action of gravity, and the garbage bags being in a molten state when heated, the downward force will cause the heated section of the garbage bags to be damaged, thus affecting the normal operation of heat sealing and hot cutting, resulting in major defects such as loose packing and liquid leakage, and affecting the user experience.

Summary of the Invention

[0003] In order to overcome the above problems, the present invention proposes a method for realizing automatic packing of waste equipment that can effectively solve the above problems.

[0004] A technical solution provided by the present invention to solve the above technical problems is: to provide a method for realizing automatic packing of waste equipment, including an automatic packing device, the automatic packing device includes a garbage bag assembly and an action unit device, and the garbage bag assembly is fixed to the automatic packing device in a detachable manner; the garbage bag assembly includes a garbage bag fixing device and a garbage bag, and the garbage bag fixing device is used to fix the garbage bag to the automatic packing device; waste enters the garbage bag from the waste inlet, and after the action unit device receives a packing instruction, it performs packing processing on the garbage bag; the action unit device includes a closing device, and the closing device includes a pressing component that can approach and separate, and the pressing component is used to close the mouth of the garbage bag, heat seal and cut it, and the pressing component includes a first pressing component and a second pressing component arranged opposite to each other; the action unit device further includes a clamping device, and the clamping device includes an upper clamping component and a lower clamping component; the upper clamping component includes a first clamping member and a second clamping member that can approach and separate; the lower clamping component includes a third clamping member and a fourth clamping member that can approach and separate; when the mouth of the garbage bag is closed and the first pressing component and the second pressing component approach each other, the first clamping member and the second clamping member also approach each other, and the third clamping member and the fourth clamping member also approach each other, and the approach of the two groups of clamping members is earlier than the approach of the first pressing component and the second pressing component. The core function of the first, second clamping members and the third, fourth clamping members is to have the function of clamping the garbage bag. Among them, the forms of the second and fourth clamping members can be independent components or other equivalent forms.

[0005] Preferably, the first clamping member includes a first elastic device, and the third clamping member includes a second elastic device; the clamping device further includes a clamping member guiding structure, and the first clamping member and the third clamping member can slide on their respective corresponding clamping member guiding structures. Preferably, the second clamping member and the fourth clamping member also include elastic devices and can also slide on their respective corresponding clamping member guiding structures.

[0006] Preferably, the first pressing assembly includes a first pressing base, a first heating assembly, and a second heating assembly; the second pressing assembly includes a second pressing base and a buffer device; the first heating assembly is connected to the first pressing base, and the first heating assembly includes a first electric heating wire and a first heat conducting diaphragm; the first electric heating wire is provided with two heating zones a and b parallel to the first direction in the first direction; the second heating assembly is fixed on the first pressing base, and the second heating assembly includes a second electric heating wire and a second heat conducting diaphragm; in the second direction, the second heating assembly is located in the middle of the heating zones a and b; in the third direction, when the two pressing assemblies approach and squeeze, the second heating assembly is higher than the heating zones a and b; in the third direction, the first heat conducting diaphragm is above the first electric heating wire, and the second heat conducting diaphragm is above the second electric heating wire; the buffer device is fixed to the second pressing base, and the buffer device includes a buffer sheet and a third heat conducting diaphragm; the buffer sheet is below the second pressing base in the third direction; the third heat conducting diaphragm is below the buffer sheet in the third direction.

[0007] Preferably, the first electric heating wire and the second electric heating wire respectively have independently controllable heating circuits; the first pressing assembly and the second pressing assembly include at least one temperature sensor. The preferred method is to each have an independent temperature sensor.

[0008] Preferably, the pressing assembly includes a first heat receiving section limiting structure, a second heat receiving section limiting structure, a third heat receiving section limiting structure, and a fourth heat receiving section limiting structure; when the first pressing assembly and the second pressing assembly approach, the first heat receiving section limiting structure, the second heat receiving section limiting structure, the third heat receiving section limiting structure, and the fourth heat receiving section limiting structure jointly limit the moving range of the heat receiving section of the garbage bag in the first direction, and this moving range is smaller than the length of the second electric heating wire in the first direction.

[0009] Preferably, the automatic bagging device includes an RFID reading function. The device body has an RFID reader circuit, and the garbage bag assembly used by the device also has an RFID tag, and the RFID tag can be used to store information about the garbage bag; the RFID tag is located at the lower end of the garbage bag fixing device in the second direction; the RFID reader circuit is located below the RFID tag in the second direction.

[0010] Preferably, the automatic packing device includes a negative pressure exhaust device and a device container. The negative pressure exhaust device is located on the outer peripheral side of the device container. When the negative pressure exhaust device operates, it sucks out the air in the device container, making the air pressure in the device container lower than the external air pressure. Thus, under the action of the pressure difference, the garbage bag is pressed downward by the air pressure in the second direction, so as to cover the device container completely, achieving the effect of automatic bag laying.

[0011] Preferably, the automatic packing device includes a hot cutting monitoring device for judging whether the cutting of the garbage bag is successful. The hot cutting monitoring device uses a contact switch, which includes a first contact point and a second contact point of the contact switch arranged oppositely. If the contact switch is turned on within a preset time after the hot cutting is completed, it indicates that the hot cutting is successful; otherwise, if the contact switch is not turned on, it indicates that the hot cutting fails.

[0012] Preferably, the automatic packing device includes a roller pulling-down structure for pulling down the garbage bag. The roller pulling-down structure includes a roller power transmission device and a roller assembly. The roller assembly includes a first roller assembly and a second roller assembly. The first roller assembly and the second roller assembly surround the outer peripheral side of the garbage bag and are relatively positioned. Preferably, they are placed at both ends of the pressing assembly in the first direction and are fixed on the action unit device at a position higher than the pressing assembly in the second direction. The first roller assembly includes at least a first roller and a second roller that can approach each other. The second roller assembly includes at least a third roller and a fourth roller that can approach each other.

[0013] Preferably, the automatic packing device includes a negative pressure structure, which is located between the pressing assembly and the roller pulling-down structure in the second direction. The negative pressure structure includes a negative pressure sealing assembly and a fan. The negative pressure sealing assembly includes at least two opening and closing flaps, which are respectively a first opening and closing flap and a second opening and closing flap. The first opening and closing flap and the second opening and closing flap are fixed on the closing device. In the third direction, the two opening and closing flaps can approach and separate from each other. When the two opening and closing flaps approach, the upper ends are closely attached to the lower end of the dirt storage cavity, thus jointly forming a sealed cavity with the garbage bag and the dirt storage cavity. When the fan sucks air, a negative pressure is formed in this cavity, thus achieving the bag laying effect of the dirt storage cavity.

[0014] The materials used for the first heat-conducting diaphragm, the second heat-conducting diaphragm, and the third heat-conducting diaphragm of the present invention have non-sticking properties, and preferably Teflon materials are used.

[0015] Compared with the prior art, the method for realizing automatic packaging of waste equipment of the present invention is that when the first and second pressing components are closed, the first clamping part and the second clamping part of the upper clamping component are close to and closed earlier than the first and second pressing components. When the spring is compressed to a predetermined position under the pressure of the transmission mechanism, the first and second pressing components are closed in place; the same is true for the lower clamping component; conversely, when the heating is completed, the first and second pressing components first move away from each other. At this time, the first and second clamping components still maintain the state of clamping the garbage bag under the action of the spring force. If the garbage bag is adhered to the heating component of the pressing component at this time, the clamping component will generate pulling force on the garbage bag, thereby separating the garbage bag from the heating component, which can effectively avoid the problem of adhesion of the garbage bag when it is hot. During heat sealing and hot cutting, the garbage bag and the waste inside it will pull the molten garbage bag under the action of gravity, causing damage to the heat-sealed and hot-cut parts of the garbage bag, thereby causing leakage and causing a poor user experience. The lower clamping component can hold the garbage bag stable, ensuring that the heat-sealing and hot-cutting links are not affected, thereby improving the stability and reliability of waste packaging and enhancing the user experience.

It should be understood that the specific implementation examples described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only relative positions on the specified view, rather than absolute positions.

[0028] In addition, in the present invention, descriptions such as "first" and "second" are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] Please refer to Figures 1 to 10 , for the method of automatically packing waste equipment in the present invention, it includes an automatic packing device, and the automatic packing device at least includes a body shell 1, a garbage bag assembly 2, and an action unit device 3. The garbage bag assembly 2 is fixed to the equipment body in a detachable manner, preferably fixed at the waste inlet 4 of the body shell 1.

[0030] The garbage bag assembly 2 at least includes a garbage bag fixing device 201 and a garbage bag 202, and the garbage bag fixing device 201 is used to fix the garbage bag 202 to the automatic packing device. Waste enters the garbage bag 202 from the waste inlet 4, and after the action unit device 3 receives a packing instruction, it performs packing processing actions such as closing the mouth, heat sealing, and hot cutting on the garbage bag 202, thereby achieving the effect of automatic packing.

[0031] The action unit device 3 at least includes a frame table 9, a mouth-closing device 10, and a power transmission device 5; the mouth-closing device 10 at least includes a pressing component that can approach and move away from each other, and preferably further includes a first mouth-closing plate 14, a second mouth-closing plate 15, a third mouth-closing plate, and a fourth mouth-closing plate that can approach and move away in the first direction 6. In the second direction 7, the first and second mouth-closing plates are above the pressing component, and the third and fourth mouth-closing plates are below the pressing component; the frame table 9 can be used to place the mouth-closing device 10 and the power transmission device 5.

[0032] The pressing assembly is used to close the mouth of the garbage bag 202, heat-seal it and cut it, and includes a first pressing assembly 12 and a second pressing assembly 13 which are arranged oppositely. The first pressing assembly 12 includes a first pressing base 16, a first heating assembly 17, and a second heating assembly 18; the second pressing assembly 13 includes a second pressing base 19 and a buffer device 20.

[0033] The first heating assembly 17 is connected to the first pressing base 16 and includes a first electric heating wire 1701 and a first heat-conducting diaphragm 1702; the first electric heating wire 1701 is provided with two a heating zones 1703 and b heating zones 1704 that are parallel or nearly parallel to the first direction 6 in the first direction 6.

[0034] The second heating assembly 18 is fixed on the first pressing base 16 and includes a second electric heating wire 1801 and a second heat-conducting diaphragm 1802; the second heat-conducting diaphragm 1802 can be an independent heat-conducting diaphragm or integrated with the first heat-conducting diaphragm 1702. The preferred way is independent heat-conducting diaphragms for each; in the second direction 7, the second heating assembly 18 is located in the middle of the a heating zone 1703 and the b heating zone 1704. In the third direction 8, when the two pressing assemblies approach and squeeze, the second heating assembly 18 is higher than the a heating zone 1703 and the b heating zone 1704. In the third direction 8, the first heat-conducting diaphragm 1702 is above the first electric heating wire 1701, and the second heat-conducting diaphragm 1802 is above the second electric heating wire 1801.

[0035] The buffer device 20 is fixed on the second pressing base 19 and includes a buffer sheet 2001 and a third heat-conducting diaphragm 2002; the buffer sheet 2001 is below the second pressing base 19 in the third direction 8 and needs to have the characteristic of flexibility. It can be made of a variety of different materials. The preferred way is to use a silicone material. The third heat-conducting diaphragm 2002 is below the buffer sheet 2001 in the third direction 8.

[0036] The materials used for the first heat-conducting diaphragm 1702, the second heat-conducting diaphragm 1802, and the third heat-conducting diaphragm 2002 have non-sticking properties. The preferred material is Teflon.

[0037] The third direction 8 is the direction perpendicular to the pressing surface of the pressing assembly, the first direction 6 is the direction parallel to the long side of the pressing assembly, and the second direction 7 is the direction perpendicular to both the first direction 6 and the third direction 8.

[0038] The motion unit device 3 further includes a clamping device 26. The clamping device 26 is fixed on the motion unit device 3 and includes an upper clamping assembly 2601 and a lower clamping assembly 2602.

[0039] The upper clamping assembly 2601 is located above the first heating assembly 17 in the second direction 7, and includes two first clamping members 2611 and second clamping members 2612 that can approach and separate from each other in the third direction 8. The first clamping member 2611 and the second clamping member 2612 are preferably mutually engageable;

[0040] The lower clamping assembly 2602 is located below the first heating assembly 17 in the second direction 7, and includes two third clamping members 2621 and fourth clamping members 2622 that can approach and separate from each other in the third direction 8. The third clamping member 2621 and the fourth clamping member 2622 are preferably mutually engageable;

[0041] The first clamping member 2611 and the third clamping member 2621 are on the same side as the first pressing assembly 12 in the third direction 8, and the second clamping member 2612 and the fourth clamping member 2622 are on the same side as the second pressing assembly 13.

[0042] When the garbage bag 202 is closed and the first pressing assembly 12 and the second pressing assembly 13 approach each other, the first clamping member 2611 and the second clamping member 2612 also approach each other and approach earlier than the first pressing assembly 12 and the second pressing assembly 13; similarly, the third clamping member 2621 and the fourth clamping member 2622 also approach each other and approach earlier than the first pressing assembly 12 and the second pressing assembly 13.

[0043] The core function of the upper clamping assembly 2601 and the lower clamping assembly 2602 is to have a clamping function. Therefore, the second clamping member 2612 and the fourth clamping member 2622 can be independent components, can form an integral body with other components, can be a plane, or other equivalent forms.

[0044] The first clamping member of the clamping device 26 includes a first elastic device 2701, and the first elastic device 2701 is preferably a spring; similarly, the third clamping member includes a second elastic device 2702, and the second elastic device 2702 is preferably a spring; the same applies to the second and fourth clamping members.

[0045] The clamping device 26 further includes a clamping member guiding structure 21. The clamping member guiding structure 21 can be a clamping member guiding rod and / or a clamping member guiding groove. The clamping member with an elastic device can slide on its corresponding clamping member guiding structure 21; the clamping member guiding structure 21 can be a separate component or can form an integral body with the clamping member with an elastic device, and is preferably formed as an integral body with the clamping member with an elastic device.

[0046] When the garbage bag 202 is closed at the mouth and the first pressing component 12 and the second pressing component 13 approach each other, the first clamping member 2611 pushes the garbage bag 202 towards the second clamping member 2612 and approaches first compared to the first pressing component 12 and the second pressing component 13. At this time, the garbage bag 202 is squeezed by the first clamping member 2611 and the second clamping member 2612, and the spring is compressed, forming a clamping effect on the garbage bag 202; conversely, when the first clamping member 2611 and the second clamping member 2612 move away, if the garbage bag 202 is adhered to the heating component at this time, the first clamping member 2611 and the second clamping member 2612 still maintain clamping and do not move under the action of the spring force, while the first pressing component 12 and the second pressing component 13 are separating at this time, that is, the adhered part of the garbage bag 202 is moving away from the clamped part, thereby generating a pulling force to separate the garbage bag 202 from the heating component.

[0047] The first heating wire 1701 and the second heating wire 1801 respectively have independently controllable heating circuits; the first pressing component 12 and the second pressing component 13 further include at least one temperature sensor. Preferably, the first heating component 17 and the second heating component 18 respectively include a first temperature sensor 1705 and a second temperature sensor 1804.

[0048] The first pressing component 12 and the second pressing component 13 respectively include a first heat-receiving section limiting structure 22, a second heat-receiving section limiting structure 23, a third heat-receiving section limiting structure 24, and a fourth heat-receiving section limiting structure 25. When the first pressing component 12 and the second pressing component 13 approach each other, the first heat-receiving section limiting structure 22, the second heat-receiving section limiting structure 23, the third heat-receiving section limiting structure 24, and the fourth heat-receiving section limiting structure 25 jointly limit the movement range of the heat-receiving section 2022 of the garbage bag 202 in the first direction 6, and this movement range is smaller than the length of the second heating wire 1801 in the first direction 6;

[0049] The preferred forms of the first heat-receiving section limiting structure 22, the second heat-receiving section limiting structure 23, the third heat-receiving section limiting structure 24, and the fourth heat-receiving section limiting structure 25 are hook-shaped structures.

[0050] When the garbage bag 202 is closed at the mouth, the heated parts of the garbage bag 202 are randomly gathered together, and the stacking layers are relatively random. Especially the edge parts in the first direction 6 are usually thinner, resulting in uneven thickness of the heat-receiving section 2022 of the garbage bag 202 after closing the mouth. Usually, the middle part is thick and the edge part is thin. However, the current heat-sealing and heat-cutting technology has requirements for the uniformity of the heated material, otherwise it is easy to cause poor consistency in heat-sealing and heat-cutting effects.

[0051] The design purposes of the first heating section limiting structure 22, the second heating section limiting structure 23, the third heating section limiting structure 24, and the fourth heating section limiting structure 25 are to improve and solve the above problems:

[0052] When the garbage bag 202 is closed, the first closing plate 14 and the second closing plate 15 move towards each other in the first direction 6 until a preset distance is reached. Here, the preset distance is less than the moving range of the heated section of the garbage bag in the first direction 6 by the first heating section limiting structure 22, the second heating section limiting structure 23, the third heating section limiting structure 24, and the fourth heating section limiting structure 25 described above; at this time, the first pressing assembly 12 and the second pressing assembly 13 also simultaneously approach and squeeze the garbage bag 202. Under the pressure of the first pressing assembly 12 and the second pressing assembly 13, the edge portions of the heated section of the garbage bag 202 spread to both sides in the first direction 6, while at this time, the first heating section limiting structure 22, the second heating section limiting structure 23, the third heating section limiting structure 24, and the fourth heating section limiting structure 25 limit the spread of the garbage bag 202, causing the edge portions of the heated section of the garbage bag to gather together, avoiding the edge portions from being too thin, and making the total thickness of the heated section of the garbage bag approximately consistent, providing a basic condition for heat sealing and hot cutting operations.

[0053] The automatic packaging device includes an RFID reading function. The device body has an RFID reader circuit 28, and the garbage bag assembly 2 used by the device also has an RFID tag 29. The RFID tag 29 can be used to store information such as the manufacturer information and garbage bag parameters of the garbage bag. The RFID tag 29 is located at the lower end of the garbage bag fixing device 201 in the second direction 7. The RFID reader circuit 28 is located below the RFID tag 29 in the second direction 7.

[0054] When the garbage bag assembly 2 is placed at the corresponding position of the device, the RFID reader circuit 28 can read the information of the RFID tag 29; the RFID reading function is preferably implemented using NFC reading and writing technology.

[0055] The automatic packaging device includes a negative pressure air extraction device 30 and a device container. The negative pressure air extraction device 30 is located on the outer peripheral side of the device container. When the negative pressure air extraction device 30 operates, it extracts the air in the device container, making the air pressure in the device container lower than the external air pressure. Thus, under the action of the pressure difference, the garbage bag 202 is pressed downward by the air pressure in the second direction 7, so as to cover the device container, achieving the effect of automatic bag laying.

[0056] The automatic packaging equipment includes a heat-cutting monitoring device 31, which is used to determine whether the garbage bag 202 is cut successfully; the heat-cutting monitoring device 31 can be implemented by a contact switch, an infrared radiating tube, ultrasonic monitoring, a camera, etc. The preferred method is to use a contact switch, and the contact switch includes a first contact point 3101 and a second contact point 3102 of the contact switch that are relatively set; when the contact switch is turned on within a preset time after the thermal cutting is completed, it indicates that the thermal cutting is successful; conversely, if the contact switch is not turned on, it indicates that the thermal cutting has failed.

[0057] Before the hot cutting of the garbage bag 202 is completed, the two contacts of the hot cutting monitoring device 31 are separated by the garbage bag 202 and cannot be connected; when the hot cutting of the garbage bag 202 is completed, the clamping mechanism is released and then closed, and two situations occur at this time: Situation 1, the garbage bag and the waste inside fall under the action of gravity, and after the clamping mechanism is closed, the two contacts of the hot cutting monitoring device 31 are connected, indicating that the hot cutting is successful; Situation 2, the garbage bag and the waste inside do not fall, and after the clamping mechanism is closed, the two contacts are still not connected, indicating that the hot cutting fails.

[0058] When eager failure occurs, if the system is unaware and continues to run new packaging work, it will cause packaging failure or leakage after packaging without the user knowing, resulting in a very bad user experience.

[0059] The automatic packaging equipment includes a roller pull-down structure 40 for pulling down the garbage bag 202; the roller pull-down structure 40 includes a roller power transmission device 34 and a roller assembly; the roller assembly includes a first roller assembly 35 and a second roller assembly 36, the first roller assembly 35 and the second roller assembly 36 surround the outer peripheral side of the garbage bag 202 and are positioned opposite to each other, preferably placed at both ends of the pressing assembly in the first direction 6, slightly above the pressing assembly in the second direction 7, and fixed on the action unit device 3; the first roller assembly 35 includes at least a first roller 3501 and a second roller 3502 that can approach each other. Similarly, the second roller assembly 36 includes at least a third roller 3601 and a fourth roller 3602 that can approach each other.

[0060] The first roller 3501 and the second roller 3502 may be rollers meshing with each other, or rollers with surfaces coated with plastic, and the method of coating the surfaces with plastic is preferred.

[0061] The third roller 3601 and the fourth roller 3602 can be rollers meshing with each other, or rollers with surfaces coated with plastic, and the rollers with surfaces coated with plastic are preferred.

[0062] The automatic packing device includes a negative pressure structure. The negative pressure structure is located between the pressing component 12 and the roller pulling-down structure 40 in the second direction 7, and includes a negative pressure sealing component 32 and a fan 33. The negative pressure sealing component 32 includes at least two opening and closing flaps, which are respectively a first opening and closing flap 3201 and a second opening and closing flap 3202. The first opening and closing flap 3201 and the second opening and closing flap 3202 are fixed on the closing device 10. In the third direction 8, the two opening and closing flaps can approach and move away from each other, and their approaching and moving away actions are synchronized with the approaching and moving away actions of the two pressing components. When the two opening and closing flaps approach, the upper ends closely fit the lower end 38 of the dirt receiving cavity 37, so as to jointly form a relatively sealed cavity with the garbage bag 202 and the dirt receiving cavity 37. When the fan 33 sucks air, a negative pressure is formed in this cavity, thereby realizing the bag laying effect of the dirt receiving cavity.

[0063] The second pressing component 13 further includes a third heating wire 39. The third heating wire 39 has two c heating zones 3901 and d heating zones 3902 parallel or nearly parallel to the first direction 6 in the first direction 6. When the first pressing component 12 and the second pressing component 13 approach each other, the c and d heating zones correspond to the a and b heating zones; thus, the garbage bag is heated simultaneously from both sides of the heated section of the garbage bag, shortening the time of hot melt sealing and heating the garbage bag more evenly.

[0064] The third heating wire 39 can have an independent heating control circuit or share the heating control circuit with the first heating wire 1701. The preferred method is to share the heating control circuit with the first heating wire 1701.

[0065] The second heating component 18 further includes a hot cutting base 1803 for fixing the third heating wire 39, which needs to be made of a high-temperature resistant material. The preferred method is to use a ceramic material. The hot cutting base 1803 is located between the second heating wire 1801 and the first pressing base 16 in the third direction 8, and is located between the a heating zone 1703 and the b heating zone 1704 in the second direction 7. A linear groove 1806 is provided on the hot cutting base 1803, and the second heating wire 1801 is located in the linear groove 1806.

[0066] Compared with the prior art, the method for automatically packing waste by the present invention has the following beneficial effects:

[0067] 1. When the first and second pressing components are closing, the first clamping member and the second clamping member of the upper clamping component approach and close earlier than the first and second pressing components close. Under the pressure of the transmission mechanism, when the compression spring reaches a predetermined position, the first and second pressing components close in place; the same applies to the lower clamping component.

[0068] On the contrary, when the heating is completed, the first and second pressing components will first move away from each other. At this time, the first and second clamping components will still maintain the state of clamping the garbage bag under the action of the spring force. If the garbage bag is adhered to the heating component of the pressing component at this time, the clamping component will generate pulling force on the garbage bag, thereby separating the garbage bag from the heating component, which can effectively avoid the adhesion problem of the garbage bag during hot cutting. During heat sealing and hot cutting, the lower clamping component can clamp the garbage bag to keep it stable, ensuring that the heat sealing and hot cutting links are not affected, thereby improving the stability and reliability of waste packaging and enhancing the user experience.

[0069] 2. Heating both sides simultaneously improves the heating speed, shortens the user's waiting time, makes the heating more uniform, and achieves better heat sealing effects. The first and second heating wires are independently controlled, which can more accurately control the heating curves of heat sealing and hot cutting, and achieve more ideal heat sealing and hot cutting effects.

[0070] 3. Through the limiting structure of the heated section, when the first and second pressing components are brought close to squeeze the garbage bag, the edge parts of the garbage bag will be stacked under the action of the limiting structure, avoiding too few stacking layers at the edge parts (the middle part is stacked relatively evenly overall), so that the overall stacking number of the garbage bag is relatively even, making the heat sealing and hot cutting processes easier to control.

[0071] 4. Heat sealing and hot cutting have relatively high requirements on the material of garbage bags. By adding RFID reading and writing functions to the equipment, users can avoid changing materials at will and avoid equipment failures caused by material mismatch.

[0072] 5. The contact heat-cut monitoring device can effectively determine whether the garbage bag is heat-cut successfully, avoiding malfunction or equipment damage caused by the user continuing to use it without knowing it when the heat-cut fails.

[0073] 6. The heat cutting base prevents the heat of the hot-cut heating wire from being transferred to the heat sealing circuit, which is conducive to precise temperature control.

[0074] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any modifications, equivalent substitutions and improvements made within the concept of the present invention should be included in the patent protection scope of the present invention.
