Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Example 1:

[0027] This embodiment provides a garment thread trimming device, specifically as follows: Figure 1 , Figure 3 , Figure 4 , Figure 5As shown, a garment thread cutting device includes a thread cutting section and an exhaust section. The exhaust section includes a negative pressure fan and an air pipe 103. The negative pressure fan is connected to the thread cutting section through the air pipe 103. The thread cutting section includes a housing 105 and a cutting unit, a combing unit, and a handle 104 mounted on the housing 105. The cutting unit includes a fixed trimming scissors 113, a movable trimming scissors 119, and a cutting drive group. The cutting drive group drives the movable trimming scissors 119 to reciprocate linearly and cooperate with the fixed trimming scissors 113 to cut the thread ends. The combing unit includes a combing roller 111, a brush 112, and a combing drive group. The combing drive group drives the combing roller 111 to rotate, and the brush 112 lifts the thread ends that are attached to the surface of the garment.

[0028] When trimming loose threads on the surface of clothing, a negative pressure fan is activated. The worker holds handle 104 and places the bottom of outer casing 105 against the garment. At this time, air at the thread cutting section is drawn to the negative pressure fan through air pipe 103, which helps the thread stand up under negative pressure and prevents the thread from sticking to the surface of the garment and not being cut. Then, the cutting drive group and the combing drive group are activated. The drive frame 118 moves back and forth against the movable trimming scissors 119 to generate cutting force. When the combing roller 111 drives the brush 112 to rotate, the brush 112 also combs up the loose threads sticking to the surface of the garment. Especially for some long threads, which are more flexible and relatively heavy, it is difficult for negative pressure to pick them up. Therefore, the combing unit is needed to assist in combing the threads and ensure that the root of the thread can be cut by the drive frame 118 and the movable trimming scissors 119. This solves the problem of some long threads being difficult to cut and greatly improves the trimming quality.

[0029] Example 2:

[0030] This embodiment further extends the above embodiment, specifically as follows: Figures 3-5 As shown, the shearing drive assembly includes a trimming motor 110, a crank 117, and a drive frame 118. The trimming motor 110 and the fixed trimmer 113 are fixedly connected to the housing 105. The crank 117 is installed at the output end of the trimming motor 110. The drive frame 118 is slidably connected to the fixed trimmer 113. The drive frame 118 is detachably connected to the movable trimmer 119. The crank 117 cooperates with the drive frame 118.

[0031] When the trimming motor 110 is started, the trimming motor 110 drives the crank 117 to rotate, and the crank 117 drives the drive frame 118 to move back and forth. At this time, the drive frame 118 drives the movable trimming shears 119 to move synchronously. If the movable trimming shears 119 is damaged, it can be disassembled and replaced.

[0032] The combing drive assembly includes a combing motor 114 and a belt 115. The combing motor 114 is fixedly connected to the housing 105, and the combing motor 114 and the combing roller 111 are connected by the belt 115.

[0033] Both the carding roller 111 and the carding motor 114 are equipped with pulleys, and a belt 115 is fitted onto the pulleys. When the carding motor 114 starts, the belt 115 drives the carding roller 111 to rotate. Figure 3 For example, at this time, the combing roller 111 rotates counterclockwise.

[0034] Furthermore, multiple sets of brushes 112 are detachably inserted into the combing roller 111 in a circumferential array. If the thread ends are tangled on the brushes 112 and inconvenient to clean, a single brush 112 can be disassembled without disassembling the outer casing 105, the thread ends can be cleaned, and then the brushes can be reassembled, which facilitates daily maintenance.

[0035] Furthermore, the outer casing 105 is provided with auxiliary teeth 116, which cooperate with the brush 112. By setting the auxiliary teeth 116 to comb the brush 112, the tangled threads on the brush 112 can be separated and then sucked away by negative pressure, reducing the frequency of daily maintenance.

[0036] Furthermore, a partition 109 is provided on the outer casing 105 to separate the shearing unit from the combing unit. Separating them by the partition 109 prevents thread ends from drifting to the shearing unit and affecting its operation, thus improving stability.

[0037] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0038] Example 3:

[0039] This embodiment further extends the above embodiment, specifically as follows: Figure 2 , Figure 6 As shown, the exhaust unit also includes a pipe management unit, which includes a storage box 101, a rotating shaft 102, a storage tray 106, and a torsion spring 107. The rotating shaft 102 is fixedly connected to the storage box 101, and the storage tray 106 is rotatably connected to the rotating shaft 102. A torsion spring 107 is provided at the connection between the two. The air pipe 103 is wound around the storage tray 106. The storage box 101 is installed on a high wall or related equipment. When trimming is needed, the worker holds the handle 104, overcomes the elastic force of the torsion spring 107, and pulls the storage tray 106 to rotate. At this time, the air pipe 103 is released, and the trimming operation can be carried out normally. When the worker releases the handle 104, the outer shell 105 returns to its original position under the elastic force of the torsion spring 107. At this time, the air pipe 103 is wound around the storage tray 106 again, preventing the outer shell 105 from occupying the work surface space and facilitating storage.

[0040] Furthermore, a spiral reinforcing steel wire 120 is provided on the air pipe 103, and a power cord 108 is installed inside the air pipe 103. The power cord 108 is used to supply power to the wire end cutting part.

[0041] The strength of the air tube 103 is enhanced by reinforcing steel wire 120 to prevent it from being flattened during winding, which would affect the air extraction effect; the power cord 108 is threaded inside the air tube 103 so that the power cord 108 is not exposed, thus preventing winding.

[0042] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0043] 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. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
