Description

Technical Field

[0001] The invention relates to a garbage can, in particular to a classified fully automatic bagging garbage can. Background Art

[0002] Trash cans are an essential sanitation equipment and household item for every household, and are closely related to a family's living environment. With the improvement of people's living standards and the enhancement of their awareness of sanitation and environmental protection, people's requirements for the sanitation environment of themselves and their families are constantly increasing, but trash cans, as essential household items, have never been improved. For example, there are a series of problems such as inconvenient bag removal, difficulty in bagging, dirty hands when packing garbage bags, etc.

[0003] In addition, the garbage problem is becoming increasingly prominent in today's society. Studies have shown that the best way to solve the garbage problem is to timely classify the garbage generated in the consumption process and recycle it for reuse. Residential garbage cans focus on the principle of simplicity and practicality, and mostly use a single cylindrical structure, which cannot achieve garbage recycling. Summary of the invention

[0004] The purpose of the present invention is to provide a classified fully automatic bagging trash can.

[0005] The object of the present invention is achieved through the following technical scheme: a classified fully automatic bagging trash can, which includes a barrel body, two bag discharging devices arranged on the left and right sides of the upper part of the barrel body, and a bottom sealing and trimming device, a side sealing device, and a bag dividing device arranged on the lower side of the bag discharging device; the bag discharging device includes a garbage bag roller extending forward and backward, and the garbage bag roller is made of a single-layer film; a bag feeding device is provided between the bag discharging devices to bond the single-layer films on both sides to form a double-layer film and convey it downward; the bottom sealing and trimming device includes two transverse pressing blocks arranged on the left and right sides of the double-layer film and a driving mechanism A for driving the two transverse pressing blocks to open and close each other; the pressing surfaces of the transverse pressing blocks are provided with upper heat sealing devices for sealing the bottom edge of the upper bag body at intervals from top to bottom The side edge sealing device is arranged at the lower side of the bottom sealing and trimming device, and the side edge sealing device includes two groups of outer longitudinal pressing components arranged at intervals in front and behind, and a driving mechanism B for driving the outer longitudinal pressing components to open and close; each outer longitudinal pressing component includes two outer longitudinal pressing blocks arranged on the left and right sides of the double-layer film, and the pressing surfaces of the outer longitudinal pressing blocks are provided with side heat sealing strips for sealing the two sides of the bag body; the bag dividing device includes several groups of inner longitudinal pressing components arranged between the outer longitudinal pressing components, and each inner longitudinal pressing component includes two inner longitudinal pressing blocks arranged on the left and right sides of the double-layer film, and the pressing surfaces of the inner longitudinal pressing blocks are provided with two inner heat sealing strips at intervals from front to back.

[0006] Compared with the prior art, the advantages of the present invention are:

[0007] 1. The present invention arranges two bag discharging devices on the left and right sides of the upper part of the barrel body. The bag discharging device is a garbage bag roller made of a single-layer film. The single-layer film on both sides is bonded and conveyed to the bottom sealing and trimming device and the side sealing device through the bag feeding device, and is heat-sealed to form a garbage bag with an open upper end. Since the left and right sides of the garbage bag are fixed by the bag discharging device, the upper end will naturally open to form a garbage throwing opening, and there is no need to specially arrange a bag opening opening device. In addition, the garbage bag roller is simple to manufacture and is convenient for users to replace.

[0008] 2. Several groups of inner longitudinal pressing components are arranged between the two outer longitudinal pressing components, and each inner longitudinal pressing component includes two inner longitudinal pressing blocks arranged on the left and right sides of the double-layer film. Two inner heat sealing strips are arranged at intervals from front to back on the pressing surfaces of the inner longitudinal pressing blocks, and a longitudinal hot-breaking strip or a longitudinal point hot-breaking strip is also arranged between the two inner heat sealing strips. The inner longitudinal pressing components can divide the bag body into several independent small bags. The small bags are used to hold different types of garbage. When the small bags are filled and sealed, different types of garbage are packaged independently, which makes it convenient for people to classify the small bags and put them into the classified garbage bins in the community to achieve secondary classification.

[0009] 3. The pressing surface of the transverse pressing block is provided with an upper heat sealing strip, a hot-breaking strip and a lower heat sealing strip at intervals from top to bottom. When the two transverse pressing blocks are pressed against each other, the bottom of the upper bag body can be sealed, the lower bag body filled with garbage can be sealed, and the lower bag body can be hot-broken and separated.

[0010] 4. The driving mechanisms of the bag feeding device, the bottom sealing and trimming device and the side sealing device not only realize synchronous driving to ensure the conveying and pressing effects, but also effectively avoid the space below the garbage throwing port, so that the garbage bags have a larger accommodating space.

DETAILED DESCRIPTION

[0019] The present invention is described in detail below with reference to the accompanying drawings and embodiments:

[0020] like Figures 1 to 7 Shown is a schematic diagram of an embodiment of a classification-type fully automatic bagging trash can provided by the present invention.

[0021] A classification type fully automatic bagging trash can, comprising a trash can body 1, two bag discharging devices 2 arranged at the left and right sides of the upper part of the trash can body 1, and a bottom sealing and trimming device 3, a side sealing device 4, and a bag separating device 6 arranged at the lower side of the bag discharging device 2;

[0022] The bag discharging device 2 comprises a garbage bag roller 2-1 extending forward and backward, and the garbage bag roller 2-1 is made of a single-layer film; a bag conveying device 5 is provided between the bag discharging devices 2 to bond the single-layer films on both sides to form a double-layer film and convey the double-layer film downward;

[0023] The bottom sealing and trimming device 3 comprises two transverse pressing blocks 3-1 respectively arranged on the left and right sides of the double-layer film and a driving mechanism A for driving the two transverse pressing blocks 3-1 to open and close each other;

[0024] The pressing surface of the transverse pressing block 3-1 is provided with an upper heat sealing strip 3-2 for sealing the bottom edge of the upper bag body, a hot breaking strip 3-3 for separating the upper and lower bag bodies, and a lower heat sealing strip 3-4 for sealing the lower bag body from top to bottom.

[0025] The side edge sealing device 4 is arranged at the lower side of the bottom edge sealing device 3, and the side edge sealing device 4 includes two groups of outer longitudinal pressing components arranged at intervals in front and back, and a driving mechanism B for driving the outer longitudinal pressing components to open and close;

[0026] Each outer longitudinal pressing assembly includes two outer longitudinal pressing blocks 4-1 arranged on the left and right sides of the double-layer film, and the pressing surface of the outer longitudinal pressing block 4-1 is provided with a side heat sealing strip 4-2 for sealing the two sides of the bag body;

[0027] The bag dividing device 6 includes several groups of inner longitudinal pressing components arranged between the outer longitudinal pressing components, each inner longitudinal pressing component includes two inner longitudinal pressing blocks 6-1 arranged on the left and right sides of the double-layer film, and the pressing surface of the inner longitudinal pressing block 6-1 is provided with two inner heat sealing strips 6-2 spaced from front to back.

[0028] A longitudinal hot-breaking strip 6-3 or a longitudinal hot-point strip is also provided between the two inner heat-sealing strips 6-2.

[0029] The longitudinal cutting strip 6-3 can be used to directly form the bag body into two small bags separated from each other.

[0030] The use of longitudinal point ironing strips can form a point break line between the two small bags. When the garbage is thrown, the two small bags are still connected together, with high strength and stability. After the garbage is taken out, the point break line can be manually torn open to achieve separation.

[0031] A connecting piece 6-4 is provided between the inner longitudinal pressing block 6-1 and the outer longitudinal pressing block 4-1 on the same side, and the two corresponding inner longitudinal pressing blocks 6-1 are driven by the connecting piece 6-4 to perform opening and closing movements.

[0032] There are two connecting pieces 6-4 between the inner longitudinal pressing block 6-1 and the outer longitudinal pressing block 4-1, which are spaced apart from each other.

[0033] The connecting member 6 - 4 is an arc-shaped curved rod, and the curvature of the arc-shaped curved rod is arranged toward the outside.

[0034] The arc-shaped curved rod arrangement provides the entire trash can with a larger space for throwing out trash.

[0035] The inner longitudinal pressing components are provided in a group and are located in the middle of the two outer longitudinal pressing components.

[0036] like Figure 2-3 As shown, the bag discharging device 2 also includes a bag storage box 2-2 for accommodating the garbage bag roller 2-1 and a guide plate 2-3 arranged on the outlet side of the bag storage box 2-2 and extending toward the middle; a bag delivery channel for allowing a single-layer film to pass through is reserved between the two guide plates 2-3, and the bag delivery device 5 is arranged at the lower side of the bag delivery channel.

[0037] The inner side of each guide plate 2-3 is provided with a plurality of notches, and the notches on the guide plates 2-3 on both sides are correspondingly arranged to form a garbage throwing opening 2-6, and the garbage throwing opening 2-6 is correspondingly arranged with the upper opening of the lower separate bag body, see Figure 7 .

[0038] A vertical guide portion 2-7 is provided on the inner edge of the garbage throwing opening 2-6.

[0039] The bag discharging device 2 also includes a cover plate 2-4 matched with the guide plate 2-3. A pair of sliding rollers 2-5 cooperating with each other are respectively arranged on the cover plate 2-4 and the guide plate 2-3. The single-layer film is located between the cover plate 2-4 and the guide plate 2-3.

[0040] The guide plate 2-3 is arranged obliquely downward.

[0041] The upper side of the bag storage box 2-2 is open, and the cover plate 2-4 is hinged to the outer upper edge of the bag storage box 2-2.

[0042] The bag feeding device 5 is arranged on the upper side of the bottom sealing and trimming device 3. The bag feeding device 5 includes two bag feeding roller groups arranged at a front-to-back interval. Each bag feeding roller group includes an active roller 5-1 and a driven roller 5-2 for clamping the side edges of two single-layer films and conveying them downward.

[0043] The driving roller 5 - 1 and the driven roller 5 - 2 are rubber rollers.

[0044] The bag feeding roller group clamps the two sides of the single-layer film respectively and draws it out from the garbage bag roller 2-1. The single-layer films on both sides are attached to each other after passing through the bag feeding roller group, and are vertically fed into the bottom sealing and trimming device 3 under the action of gravity.

[0045] Preferably, the bag feeding roller group should be located below the middle of the two bag discharging devices 2, so that a bucket-shaped throwing opening is formed at the upper end of the garbage bag, and it is also convenient for the single-layer film to be more smoothly pulled out from the garbage bag roller 2-1.

[0046] The bag feeding device 5 also includes a control component for controlling the active roller 5-1 and the driven roller 5-2 to separate from each other or to roll oppositely.

[0047] When replacing the garbage bag roller 2-1, it is only necessary to lift up the cover plate 2-4, put the garbage bag roller 2-1 into the upper opening of the bag storage box 2-2, and pull the single-layer film on the garbage bag roller 2-1 along the guide plate 2-3 to the bag feeding device 5, clamp the single-layer films on both sides by controlling the opening and closing of the operating assembly, and finally cover the cover plate 2-4.

[0048] A start switch can be set on the cover plate 2-4. When the cover plate 2-4 is closed, the program automatically controls the operation of each driving mechanism.

[0051] The operating assembly includes an articulated shaft 5-6 parallel to the rotating shaft of the driven roller 5-2, a lever 5-7 for driving the articulated shaft 5-6 to rotate, and a return spring for pressing the driven roller 5-2 against the active roller 5-1. The driven roller 5-2 is movably connected to the articulated shaft 5-6.

[0052] like Figure 5 As shown, the driving mechanism A includes motors A3-5, two groups of linkage components A spaced apart from each other, a reversing component and a guide component A;

[0053] The linkage assembly A includes a synchronization shaft A3-6 extending forward and backward, two gears A3-7 disposed at the front and rear sides of the synchronization shaft A3-6, and a rack A3-8 fixed on the lateral pressing block 3-1 on the same side and cooperating with the gear A3-7;

[0054] The reversing assembly includes a main reversing gear 3-9, a slave reversing gear 3-10 meshing with the main reversing gear 3-9, and a pulley assembly A3-11 connected between the left synchronizing shaft A3-6 and the main reversing gear 3-9; the slave reversing gear 3-10 is coaxially linked with the right synchronizing shaft A3-6;

[0055] The guide assembly A includes a guide rail A3-12 extending left and right and two sliders A3-13 arranged on the lateral pressing blocks 3-1 on opposite sides;

[0056] The motor A3-5 drives the left synchronization shaft A3-6 to rotate.

[0057] The reversing assembly arranged on the driving mechanism A enables the lateral pressing blocks 3-1 on the left and right sides to perform synchronous opening and closing movements with the double-layer film as the center.

[0058] like Figure 6 As shown, the driving mechanism B includes a motor B4-3, a synchronous shaft B4-4 extending forward and backward and driven to rotate by the motor B4-3, two linkage components B arranged at the front and rear sides of the synchronous shaft B4-4, and a guide component B;

[0059] The linkage assembly B includes a gear B4-5, two racks B4-6 disposed on the upper and lower sides of the gear B4-5 and respectively meshing with the gear B4-5, and a pulley assembly B4-7 connected between the synchronization shaft B4-4 and the gear B4-5, and the two racks B4-6 are respectively fixed on the outer longitudinal pressing blocks 4-1 on the opposite sides;

[0060] The guide assembly B includes a guide rail B4-8 extending left and right and two sliders B4-9 arranged on the outer longitudinal pressing blocks 4-1 on the opposite sides.

[0061] To determine whether the garbage bag is full, a weight sensor or an infrared sensor that senses the height of the garbage can be used, and a manual switch can be set.

[0062] The barrel body 1 is also provided with a barrel cover 1-1, and the barrel cover 1-1 is provided with an infrared sensing door corresponding to the garbage throwing opening 2-6.

[0063] In order to facilitate taking out the packaged garbage, an opening can be provided at the lower part of the garbage can, and a base matching with the lower opening can be provided.

[0064] The working process of the present invention is as follows:

[0065] 1. Remove the barrel cover 1-1, open the cover plate 2-4, and put the garbage bag roll 2-1 into the bag storage boxes 2-2 on both sides respectively;

[0066] 2. Pull the single-layer film on the garbage bag roller 2-1 along the guide plate 2-3 to the bag feeding device 5, clamp the single-layer film on both sides by controlling the opening and closing of the operating components, and cover the cover plate 2-4 and the barrel cover 1-1;

[0067] 3. Motor C5-3 drives the bag feeding rollers on both sides to rotate synchronously, the two single-layer films are clamped together, and transported downward to the bottom sealing and trimming device 3, and the bag feeding rollers stop transporting;
