Description

Technical Field

[0001] This utility model relates to the field of curtain fabric production technology, and more specifically to a rapid cutting device for a curtain fabric winding machine. Background Technology

[0002] In the production process of tire cord fabric, once a roll of fabric is wound up, it must be cut and the roll replaced within a very short time to begin the winding of the next roll. This process currently relies heavily on operators using manual scissors.

[0003] Because the fabric has extremely high strength and toughness, manual cutting requires a great deal of physical strength and is slow. On a high-speed production line, this short cutting window of a few tens of seconds is crucial. If the operator's cutting speed lags behind, the amount of fabric on the fabric rack will be too low. The fabric will sag and fold rapidly due to loss of tension. Once folding occurs, it will require machine shutdown at best, and at worst, the entire roll of fabric will be scrapped, causing production interruption and economic losses.

[0004] In addition, the uneven cuts made by manual cutting make it difficult to stick the fabric ends firmly with tape later, and they are prone to loosening in the initial stage of winding, which can also cause winding failure and further increase the operational risks of the production line. Summary of the Invention

[0005] To address the technical problems existing in the cutting of curtain fabric in the prior art, this utility model proposes a rapid cutting device for a curtain fabric winding machine, comprising: The feeding table is used to support the curtain fabric. The idler roller is located on one side of the feeding table. When the curtain fabric moves to the surface of the idler roller, it can be fixed to the surface of the idler roller by the user using adhesive tape. A support rail is provided between the feeding table and the idler roller; An electric cutting component is connected to the support rail and can move along the length direction of the support rail, which is perpendicular to the feeding direction of the curtain fabric. The electric cutting component is configured to start cutting the curtain fabric when moving in a first direction along the length of the support track, and to stop cutting the curtain fabric after a preset delay time.

[0006] Preferably, the upper surface of the supporting track is a supporting surface, and a groove is provided on the supporting surface. The groove includes a first groove and a second groove, the depth of the second groove is greater than the depth of the first groove, and the width of the second groove is greater than the width of the first groove.

[0007] Preferably, the electric cutting component is mounted on a mobile trolley, which can move within the groove of the supporting track.

Embodiments of various aspects of the present invention will now be described by way of example and with reference to the accompanying drawings, wherein: Figure 1 This is a schematic diagram of the structure of the rapid cutting device for a curtain fabric winding machine shown in this utility model; Figure 2 This is a schematic diagram of the structure of the electric cutting component and the mobile trolley shown in this utility model; Figure 3 This is a top view of the rapid cutting device for a curtain fabric winding machine shown in this utility model. Detailed Implementation

[0015] To better understand the technical content of this utility model, specific embodiments are provided below in conjunction with the accompanying drawings.

[0016] like Figure 1 As shown, this utility model proposes a rapid cutting device for a curtain fabric winding machine, including a feeding table 10, a roller 20, a support track 30, and an electric cutting component 40. The feeding table 10 is used to support the curtain fabric, and the roller 20 is arranged on one side of the feeding table 10.

[0017] The cord fabric is continuously fed from the feeder 10 toward the idler roller 20 and is continuously wound up on the other side of the idler roller 20. Whenever a roll needs to be changed, the cord fabric needs to be cut. Since the time window for changing rolls is very short, it must be cut quickly.

[0018] Specifically, when the curtain fabric moves and reaches the roll-changing condition, the curtain fabric here is attached to the surface of the idler roller 20 by the user with tape. In the prior art, it is usually cut manually by employees with scissors, but the speed cannot meet the requirements.

[0019] The support rail 30 is set between the feeding table 10 and the roller 20. The electric cutting component 40 is connected to the support rail 30 and can move along the length direction of the support rail 30. The length direction of the support rail 30 is perpendicular to the feeding direction of the curtain fabric.

[0020] The electric cutting component 40 is configured to start cutting the curtain fabric when moving in a first direction along the length of the support track 30, and to stop cutting the curtain fabric after a preset delay time.

[0021] Thus, combined Figure 1 and Figure 3 As shown, after the curtain fabric is fixed in place by tape at the position of the roller 20, the worker manually pushes the electric cutting component 40 to move in the first direction. The electric cutting component 40 quickly cuts the curtain fabric along the length of the support track 30. This process takes about 2 to 3 seconds. The cutting stops when the electric cutting component 40 has completely cut the curtain fabric.

[0022] In optional embodiments, such as Figure 1 As shown, the upper surface of the support track 30 is a support surface, and a groove is provided on the support surface. The groove includes a first groove 301 and a second groove 302. The depth of the second groove 302 is greater than the depth of the first groove 301, and the width of the second groove 302 is greater than the width of the first groove 301.

[0023] In this way, the curtain fabric can remain flat on the upper surface of the support track 30, which is conducive to the electric cutting component 40 completing a flat cut.

[0024] In an optional embodiment, combined with Figure 1 andFigure 2 As shown, the electric cutting component 40 is mounted on a mobile trolley 42, which can move within the groove of the supporting track 30.

[0025] Specifically, the mobile trolley 42 is equipped with multiple pulleys 421, which are connected to the inner wall of the second trough 302.

[0026] Thus, with the pulley 421 in place, the sliding resistance of the trolley 42 in the chute is small, and the user can push the trolley 42 to move at a faster speed, which is the basis for achieving rapid cutting. At the same time, due to the small resistance, the user can directly push the trolley to move a distance greater than the width of the curtain fabric in one go, so as to achieve one-time cutting.

[0027] Furthermore, a spring 32 is provided at one end of the mobile trolley 42, and a fixed seat 31 is provided at one end of the supporting track 30. The second end of the spring 32 is connected to the fixed seat 31. When the mobile trolley 42 moves along the first direction of the length of the supporting track 30, the spring 32 is stretched, so that the mobile trolley 42 has a tendency to return to its original position.

[0028] Thus, when the user pushes the moving trolley 42 to move, after the moving trolley 42 reaches the other end of the curtain fabric, it can still be pulled back to the origin by the spring 32. It should be understood that during the return process, the electric cutting component 40 does not rotate to avoid causing secondary damage to the cut curtain fabric. The non-rotation during the return can be achieved by delaying the closing.

[0029] In an optional embodiment, the electric cutting component 40 includes an electric drive structure 401 and a blade 402, the electric drive structure 401 being used to drive the blade 402 to rotate, the blade 402 extending into the first groove 301.

[0030] Specifically, the electric cutting component 40 is provided with a trigger handle 41. When the electric cutting component 40 is in the reset position and the trigger handle 41 is pressed, the electric drive structure 401 can drive the blade 402 to rotate and stop driving after a preset time.

[0031] Thus, when the user pushes the mobile trolley 42, the trigger handle 41 is pressed simultaneously. The pressure sensor on the trigger handle 41 detects the pressure signal, the electric drive structure 401 is activated, and it is simultaneously deactivated after a delay of 2 to 3 seconds. During these 2 to 3 seconds, the mobile trolley 42 is in the process of moving in the first direction, which is the process of cutting the curtain fabric. When returning, the electric drive structure 401 is deactivated.

[0032] The mobile cart 42 was pushed forward by the staff to cut the curtain fabric.

[0033] In the above embodiment, a connector 422 is provided above the mobile trolley 42. The connector 422 is connected to the electric cutting component 40, and the electric cutting component 40 is located on the side of the connector 422 facing the first direction.

[0034] This makes the structure of the mobile trolley 42 and the electric cutting component 40 compact, which is beneficial for the operator to control the mobile trolley to move back and forth on the surface of the supporting track 30.

[0035] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
