Description

Technical Field

[0001] This utility model relates to the field of sewing machine feeding devices, and in particular to a tape cutting and supplying device. Background Technology

[0002] In the sewing process of advertising fabric, adhesive strips need to be sewn to the advertising fabric as a whole so that they can be inserted into the slots of the advertising sign for installation. Traditionally, this involves manually pulling the adhesive strip from the feed hopper to the presser foot of the sewing machine and then manually cutting it after it reaches the preset length. After cutting, subsequent adhesive strips must be manually pulled back to the sewing machine, which is not only cumbersome and inefficient, but also prone to accidents and positioning deviations, affecting cutting accuracy and sewing continuity.

A cutting mechanism for cutting adhesive strips; including a cutting blade capable of performing the cutting action and a cutting actuator capable of driving the cutting blade to move toward the adhesive strip; and A supply unit for feeding the cut end of the adhesive strip into the presser foot of a sewing machine, including a clamping mechanism and a supply mechanism; The clamping mechanism includes a pair of clamping plates, with a channel between the pair of clamping plates for the adhesive strip to enter, and the pair of clamping plates can perform clamping actions under the drive of the clamping plate driver. The supply mechanism includes a connecting plate connected to the clamping mechanism. The connecting plate is connected to a supply driver, which can drive the connecting plate to move the clamping mechanism along the length of the clamped section of the adhesive strip.

[0005] Preferably, the clamp is configured as an L-shaped structure, having a connecting section and a clamping section perpendicular to the connecting section for clamping the adhesive strip; at least one connecting section of the clamp is fixed to the clamp driver.

[0006] Preferably, at least one of the clamps is configured as part of the connecting plate.

[0007] Preferably, a guide mechanism is provided for the cutting mechanism, the guide mechanism having a first guide portion and a second guide portion; both the first guide portion and the second guide portion allow the adhesive strip to pass through, and the gap between the first guide portion and the second guide portion allows the cutting mechanism to enter and exit.

Detailed Implementation

[0013] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., 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 between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0014] The present invention will be further described in detail below with reference to specific embodiments: like Figure 1 As shown, a tape cutting and supply device is used to supply tape 100 of a preset length to a sewing machine 200. In its application scenario, the tape 100 is sewn together with the advertising cloth in the sewing machine 200, so that the advertising cloth can be snapped into the slot in the billboard by the tape 100, thereby realizing the installation of the advertising cloth.

[0015] The adhesive strip 100 cutting and supply device includes a hopper 1 for storing and winding the adhesive strip 100. At the beginning of the adhesive strip 100 sewing operation, the adhesive strip 100 wound in the hopper 1 is pulled out by the worker from one end of the hopper 1 to the presser foot of the sewing machine 200. The sewing machine 200 can sew the adhesive strip 100 that has entered its presser foot and simultaneously pull the adhesive strip 100 to move. A cutting mechanism 3 is provided adjacent to the sewing machine 200. When the length of the adhesive strip 100 sewn meets the preset value, the cutting mechanism 3 is used to cut the adhesive strip 100.

[0016] To ensure that the adhesive strip 100 behind the cut can be re-sewed by the sewing machine 200, this application is equipped with a supply unit 2 in conjunction with the cutting mechanism 3.

[0017] Combination Figure 1 and Figure 2As shown, the supply unit 2 is located on the opposite side of the cutting end from the sewing machine 200, and includes a clamping mechanism 21 and a supply mechanism 22. The clamping mechanism 21 includes a pair of clamping plates 211, forming a channel between the plates for the adhesive strip 100 to enter. At least one of the clamping plates 211 can perform a clamping action under the action of a clamping plate driver 212, thereby clamping the adhesive strip 100 located in the channel. The clamped portion of the adhesive strip 100 is defined as the clamped segment 2112. The supply mechanism 22 includes a connecting plate 221 connected to the clamping mechanism 21. The other end of the connecting plate 221 is connected to the supply driver 222, which can drive the connecting plate 221 to move the clamping mechanism 21 along the length direction of the clamped segment 2112 of the adhesive strip 100. In this way, the clamping plate 211 holds the adhesive strip 100 and feeds the first end of the adhesive strip 100 into the presser foot of the sewing machine 200, so that the sewing work of the adhesive strip 100 can continue.

[0018] Specifically, such as Figure 3 As shown, any clamping plate 211 is configured with an L-shaped structure, having a connecting section 2111 and a clamping section 2112 perpendicular to the connecting section 2111 for clamping the adhesive strip 100. Preferably, the clamping section 2112 extends in one direction, which can achieve a better clamping effect on the adhesive strip 100. In this embodiment, one clamping plate 211 is fixedly installed, and the other clamping plate 211 is connected to the actuating end of the clamping plate driver 212 through the connecting section 2111. The clamping plate driver 212 is a cylinder.

[0019] Furthermore, in this embodiment, the fixed clamping plate 211 is constructed as part of the connecting plate 221, that is, it is formed by bending the top end of the connecting plate 221 in the horizontal direction.

[0020] like Figure 2 As shown, a guide mechanism 4 is provided corresponding to the cutting mechanism 3. The guide mechanism 4 is used to support the adhesive strip 100 when the clamping mechanism 21 is not in contact with the adhesive strip 100, and to provide positioning for the adhesive strip 100 to facilitate the cutting action of the cutting mechanism 3. The guide mechanism 4 includes a first guide portion 41 and a second guide portion 42. Both the first guide portion 41 and the second guide portion 42 can be passed through by the adhesive strip 100. The gap between the first guide portion 41 and the second guide portion 42 allows the cutting mechanism 3 to enter and exit to cut the adhesive strip 100. This arrangement ensures that the cut end of the adhesive strip 100 is located between the first guide portion 41 and the second guide portion 42. After the adhesive strip 100 is cut, the adhesive strip 100 connected to the hopper 1 can be mounted on the first guide portion 41 to prevent it from drooping, so that the subsequent clamping mechanism 21 can clamp and transport this part of the adhesive strip 100. The first guide section 41 and the second guide section 42 are both provided with rectangular guide grooves. The second guide section 42 is constructed as a flared structure to facilitate the supply mechanism 22 to insert the rubber strip 100 through it.

[0021] In addition, such as Figure 4 As shown, a tensioning mechanism 5 is provided between the discharge end of the hopper 1 and the supply unit 2 to tension the adhesive strip 100 output from the hopper 1. The tensioning mechanism 5 includes two fixed pulleys 51 and a movable pulley 52 disposed between the two fixed pulleys 51. In this embodiment, a slide rail 53 is provided in conjunction with the movable pulley 52. ​​The slide rail 53 is vertically disposed between the two fixed pulleys 51, and the movable pulley 52 is slidably disposed on the slide rail 53. The adhesive strip 100 passes through the tensioning mechanism 5 in a U-shaped trajectory, and the fixed pulleys 51 are placed between the U-shaped trajectories, enabling them to tension the adhesive strip 100 by their own weight.

[0022] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
