Description

Technical Field

[0001] This utility model relates to the technical field of garbage bag cutting devices, specifically to a reciprocating cutter head assembly used in garbage bag cutting devices. Background Technology

[0002] Currently, garbage bags are widely used as containers for collecting garbage. Most garbage bags are made of materials such as polyethylene and polypropylene, which have the value of being recyclable and reusable. Therefore, including used garbage bags in the category of recyclables for special processing has become an important part of the garbage classification system.

[0003] Since garbage bags are mostly used to hold kitchen waste in daily life, after the garbage is emptied from the garbage bag, sewage and residue are easily left inside, which can easily breed bacteria and cause odor. Garbage bags usually need to be cleaned before recycling. However, due to the many folds and narrow corners inside the garbage bag, water stains, sticky liquids and small residues inside are difficult to remove quickly through conventional cleaning methods, which affects the recycling efficiency of garbage bags. To address the aforementioned issues, there is currently a device on the market specifically designed for cutting and cleaning garbage bags. Its working principle involves using a blade to cut open the garbage bag, allowing the garbage and residual liquid inside to flow out quickly, and then being flushed with water, greatly improving the cleaning and recycling efficiency of garbage bags.

[0004] For example, the inventor recently applied for authorization in a Chinese utility model patent—Garbage Bag Cutting Device (CN214824774U)—discloses a device with garbage bag cutting and cleaning functions. It includes a housing, a cutting component, and a transmission component. When in use, the second cutting component is driven to move away from the first cutting component to widen the bag inlet. After the garbage bag is put in, the second cutting component resets and moves towards the first cutting component, clamps the garbage bag, and pulls the garbage bag. The blades of the first and second cutting components cut the garbage bag, causing the garbage collected in the garbage bag to fall into the housing. With the help of water flow, the garbage bag is rinsed, which facilitates the recycling of the garbage bag.

[0005] However, in practical applications, it has been found that since garbage usually concentrates at the bottom of the garbage bag, and the blade cuts the garbage bag from top to bottom, the bottom of the garbage bag is prone to incomplete cutting. Furthermore, after cutting, the garbage bag has a vertical strip structure, which still holds the garbage and makes it difficult for it to fall out. In order to make the garbage fall out better, it is often necessary to manually shake the garbage bag, which is quite troublesome. Utility Model Content

[0006] To address the aforementioned technical problems, this utility model provides a reciprocating cutter head assembly for a garbage bag cutting device, which can achieve lateral cutting of the lower part of the garbage bag, allowing the garbage and sewage it contains to fall out more effectively.

[0007] This utility model discloses a reciprocating cutter head assembly for a garbage bag cutting device, comprising a horizontally placed guide rail, at least one sliding cutter holder slidably mounted on the guide rail, and a drive mechanism for driving the sliding cutter holder to reciprocate laterally along the guide rail. A blade is connected to one longitudinal end of the sliding cutter holder, located below the bag inlet of the garbage bag cutting device. When the garbage bag is placed downwards along the inlet, the blade contacts the lower part of the garbage bag. The thickness direction of the blade corresponds to the longitudinal direction, and the length direction corresponds to the transverse direction. The blade includes a cutting edge arranged in the transverse direction, and the cutting edge has multiple alternately distributed tooth tips and tooth grooves in the transverse direction. The blade can move laterally along the guide rail with the sliding cutter holder, and during this transverse movement, it can perform transverse cutting on the lower part of the garbage bag. The drive mechanism drives the blade to reciprocate laterally, improving the cutting efficiency of the garbage bag. After cutting, it does not need to return to the initial position.

[0008] Furthermore, there are at least two sliding blade holders that are slidably mounted on the guide rail. The two sliding blade holders are spaced apart, which can reduce the lateral displacement distance of the sliding blade holders and further improve the cutting efficiency.

[0009] Furthermore, an extension arm is provided at one longitudinal end of the sliding knife holder, and the blade is provided at the end of the extension arm, so that the sliding knife holder and the guide rail can be positioned far away from the bag inlet, avoiding sewage, water flow, etc. from affecting the sliding performance of the sliding knife holder and the guide rail (for example, causing corrosion at the sliding joint, or affecting the adhesion of lubricating oil on the guide rail).

[0010] Furthermore, the lower end of the blade is fixed to the extension arm, and the cutting edge is located at the upper end of the blade, allowing the blade to be inserted upward into the garbage bag.

[0011] Furthermore, each extension arm is equipped with at least two blades, which are distributed longitudinally at intervals to increase the lateral cutting range of the garbage bag and further improve the cutting effect.

[0012] Furthermore, it includes multiple horizontally placed support rods, which are arranged longitudinally at intervals and form gaps 50. At each gap 50, a blade is arranged that can move laterally. The cutting edge of the blade extends upward along the gap 50, and the height of the cutting edge is higher than that of the support rod. The support rods have a limiting effect on the lower part of the garbage bag, preventing the blade from being excessively inserted into the garbage bag and preventing the garbage contents from affecting the cutting work of the blade.

[0013] Furthermore, each blade is staggered in the longitudinal direction, which further increases the cutting range and avoids repeated cutting at the same position.

[0014] Furthermore, the drive mechanism includes a steel wire and a motor / pedal / rocker that are connected and driven to both ends of the steel wire. The sliding cutter holder is fixed between the two ends of the steel wire, for example, in the middle area of ​​the steel wire. The sliding cutter holder can be driven to move laterally by electricity, foot pedal or hand crank, which is convenient to use. Attached Figure Description

Detailed Implementation

[0016] An embodiment of this utility model for a reciprocating cutter head assembly in a garbage bag cutting device, such as... Figure 1-4 As shown, the device includes a horizontally placed guide rail 1, a sliding blade holder 2 slidably mounted on the guide rail 1, and a drive mechanism for driving the sliding blade holder 2 to reciprocate laterally along the guide rail 1. The guide rail 1 consists of two sets, with both ends fixed to the side plates 71 on both sides of the housing of the garbage bag cutting device. A blade 3 is connected to one end of the sliding blade holder 2 along its longitudinal direction. This blade 3 is located below the bag inlet of the garbage bag cutting device. When the garbage bag is placed downwards along the inlet, the blade 3 can contact the lower part of the garbage bag. The thickness direction of the blade 3 corresponds to the longitudinal direction, and the length direction of the blade 3 corresponds to the longitudinal direction. In the transverse direction, the blade 3 includes a cutting edge arranged in the transverse direction. The cutting edge has multiple teeth 31 and teeth 32 that are alternately distributed in the transverse direction. This structure of the cutting edge can improve the cutting effect on plastic bags. In particular, the teeth 31 can easily penetrate into the garbage bag. The blade 3 can move laterally along the guide rail 1 with the sliding blade holder 2. During the transverse movement, it can cut the lower part of the garbage bag laterally. The transverse reciprocating motion of the blade 3 driven by the drive mechanism can improve the cutting efficiency of the garbage bag. After the cutting is completed, it does not need to be reset to the initial position.

[0017] In this embodiment, two sliding blade holders 2 are slidably mounted on the guide rail 1, and the two sliding blade holders 2 are spaced apart, which can reduce the lateral displacement distance of the sliding blade holders 2 and further improve the cutting efficiency. In other embodiments, the number of sliding blade holders 2 may be one or more.

[0018] The sliding knife holder 2 has an extension arm 4 at one longitudinal end, and the blade 3 is located at the end of the extension arm 4, so that the sliding knife holder 2 and the guide rail 1 can be located at a position far away from the bag inlet, so as to avoid sewage, water flow, etc. affecting the sliding performance of the sliding knife holder and the guide rail 1 (for example, causing corrosion at the sliding joint, or affecting the adhesion of lubricating oil on the guide rail 1). In actual application, it is set at a relatively high position relative to the slope 72 below the bag inlet.

[0019] The lower end of the blade 3 is fixed to the extension arm 4, and the cutting edge is located at the upper end of the blade 3, so that the blade 3 can be inserted upward into the garbage bag.

[0020] Each extension arm 4 is provided with at least two blades 3, which are distributed longitudinally at intervals to increase the lateral cutting range of the garbage bag and further improve the cutting effect.

[0021] In addition, it includes multiple horizontally placed support rods 5. The two ends of these support rods 5 are also fixed to the side plates 71 on both sides of the housing of the garbage bag cutting device. These support rods 5 are arranged longitudinally at intervals and form gaps 50. At each gap 50, a blade 3 is arranged that can move laterally. The cutting edge of the blade 3 extends upward along the gap 50, and the height of the cutting edge is higher than that of the support rod 5. The support rod 5 has a limiting effect on the lower part of the garbage bag, preventing the blade 3 from being excessively inserted into the garbage bag and preventing the garbage contents from affecting the cutting work of the blade 3.

[0022] like Figure 2 As shown, each blade 3 is staggered in the longitudinal direction, which further improves the cutting range and cutting efficiency, and avoids the blade 3 repeatedly cutting the same position on the garbage bag.

[0023] In this embodiment, the driving mechanism includes a steel wire 6, with both ends of the steel wire 6 movably passing through guide holes in the side plates 71 on both sides of the housing of the garbage bag cutting device. The two ends of the steel wire 6 are fixed between the sliding blade holder 2. The steel wire 6 is clamped and fixed to the upper end of the sliding blade holder 2 by screws 21. The two ends of the steel wire 6 can be wound around a winding roller in different helical directions. The winding roller is controlled by a motor to rotate in both directions, realizing the reciprocating motion of the steel wire 6. Of course, the two ends of the steel wire 6 can also be connected to the swing end of a swing arm and tightened by a tension spring. When the motor drives the swing end of the swing arm to rotate, it can drive the steel wire 6 to reciprocate. In addition, the two ends of the aforementioned steel wire 6 can also be connected to a pedal (foot pedal operation) or a rocker arm (manual operation) through a winding roller, a swing arm or other structure, to achieve manual driving.

[0024] The above embodiments are merely one preferred embodiment of the present utility model. Ordinary changes and substitutions made by those skilled in the art within the scope of the present utility model's technical solution are all included within the protection scope of the present utility model.
