Description

Technical Field

[0001] This utility model belongs to the technical field of template machines, and relates to a truss template machine. Background Technology

[0002] A template sewing machine is a highly automated industrial sewing device that uses a pre-made rigid or flexible template to precisely guide the movement of the fabric (cloth, leather, etc.) within the sewing area. The operator simply places the fabric into the template and starts the machine; the machine then automatically completes complex sewing patterns, shapes, or stitches according to the path set by the template. This greatly ensures the consistency and precision of the sewing, making it particularly suitable for high-volume, repetitive sewing operations with strict stitch requirements, such as garment pockets, collars, automotive interiors, and bag components.

[0003] A strip sewing template machine is a specialized machine for sewing strips. Strips are typically composed of multiple layers of thick, high-strength material. Therefore, the strip sewing template machine is equipped with a powerful presser foot system, using a cup-shaped presser foot as an auxiliary presser foot to ensure that the thick material remains stable, does not slip, and does not stack during the sewing process. In use, the strip is drawn into the cup-shaped presser foot via a feeding mechanism. Due to the aforementioned characteristics of strips, the thread-cutting mechanism on traditional template machines is no longer suitable; most existing strip sewing template machines use manual strip cutting. Utility Model Content

[0004] This invention addresses the shortcomings of existing technologies by providing a truss template machine equipped with a specialized tape-cutting mechanism, which improves sewing efficiency and reduces labor intensity.

[0005] To solve the above-mentioned technical problems, the objective of this utility model is achieved through the following technical solution:

[0006] A truss formwork machine includes a machine head, which is equipped with a tape feeding mechanism, an auxiliary presser foot mechanism, and a tape cutting mechanism. The tape feeding mechanism pulls the truss into the cup-shaped presser foot of the auxiliary presser foot mechanism. The tape cutting mechanism includes a displacement cylinder, a tape cutting cylinder, and a tape cutting blade. The displacement cylinder is located on one side of the auxiliary presser foot mechanism and drives the tape cutting cylinder and the tape cutting blade to move between a standby position and a working position. When the tape cutting cylinder and the tape cutting blade move to the working position, the tape cutting blade is located directly below the cup-shaped presser foot and is driven by the tape cutting cylinder to cut the truss.

[0007] In the aforementioned type of truss formwork machine, the displacement cylinder is fixed to one side of the machine head via a shearing mounting plate. A shearing connecting plate is connected to the piston rod of the displacement cylinder, and the shearing cylinder is mounted on the shearing connecting plate. Preferably, the shearing mounting plate is perpendicular to the machine head, and the displacement cylinder is preferably a double-rod type cylinder. Preferably, the shearing connecting plate is an L-shaped plate that connects the displacement cylinder and the shearing cylinder respectively. The shearing cylinder is installed below the displacement cylinder, and their axes are perpendicular.

[0008] In the above-mentioned truss formwork machine, the shearing cylinder is mounted on the shearing connecting plate via a shearing base. The shearing base is fixed with a shearing fixed blade and hinged with a shearing moving blade driven by the shearing cylinder. The shearing fixed blade and the shearing moving blade together form the shearing blade.

[0009] In the above-mentioned truss formwork machine, the shearing mechanism is inclined, and the displacement cylinder drives the shearing blade to move obliquely downward and insert directly below the bowl-shaped presser foot; furthermore, the displacement cylinder, the shearing cylinder, and the shearing blade have the same inclination angle.

[0010] In the above-mentioned truss template machine, the auxiliary presser foot mechanism includes a belt feeding cylinder, a belt pressing cylinder, and a belt feeding head. The truss belt pulled by the belt feeding mechanism passes through the belt feeding head. The belt feeding cylinder drives the belt pressing cylinder and the belt feeding head to move towards the cup-shaped presser foot. The piston rod of the belt pressing cylinder presses down to press the truss belt entering the belt feeding head.

[0011] In the above-mentioned truss formwork machine, the belt-passing cylinder is mounted on the belt-passing cylinder mounting plate. The belt-passing cylinder mounting plate and the cup-shaped presser foot are fixed to the auxiliary presser foot rod through the auxiliary presser foot connecting plate. The piston rod of the belt-passing cylinder is connected to the belt-passing head mounting plate and drives it to slide relative to the belt-passing cylinder mounting plate. The belt-pressing cylinder and the belt-passing head are both fixedly connected to the belt-passing head mounting plate. Furthermore, the piston rod of the belt-passing cylinder is set upward, and the belt-passing head mounting plate is connected to the end of the piston rod and bent downward to install the belt-passing head.

[0012] In the above-mentioned truss formwork machine, the belt-passing cylinder, the belt-passing head mounting plate, and the belt-passing head are all inclined. The belt-passing cylinder drives the belt-passing head to move obliquely downward and insert into the bowl-shaped pressure foot. Furthermore, the belt-passing cylinder, the belt-passing head mounting plate, and the belt-passing head have the same inclination angle.

[0013] In the above-mentioned type of truss template machine, the pressing cylinder is arranged vertically, and an arc-shaped support plate corresponding to the pressing cylinder is provided at the inlet of the belt head. The piston rod of the pressing cylinder cooperates with the arc-shaped support plate to form a pressing structure. Furthermore, the arc-shaped support plate is bent downward, and a nut or pressure plate that cooperates with the arc-shaped support plate is mounted on the piston rod of the pressing cylinder.

[0014] In the above-mentioned truss formwork machine, a rotating head is provided on the machine head, and the auxiliary presser foot mechanism and the strip cutting mechanism are both provided on the rotating head and rotate synchronously therewith.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] 1. This utility model provides a strip template machine. Taking into account the characteristics of strips and auxiliary presser feet, a strip cutting mechanism consisting of a displacement cylinder, a strip cutting cylinder, and a strip cutting blade is configured on the machine head. By configuring a strip cutting mechanism separately on the machine head, the space limitation requirements of conventional thread cutting mechanisms can be overcome, and a strip cutting mechanism with greater shearing force can be used to cut the strip. The displacement cylinder can drive the strip cutting mechanism to switch between the standby position and the displacement position, so that it will not interfere with the sewing work when in standby mode.

[0017] 2. This utility model further provides an auxiliary presser foot mechanism, which uses a belt feeder head driven by a belt feeder cylinder to accurately feed the belt pulled by the belt feeder mechanism into the cup-shaped presser foot. Combined with the belt pressing structure driven by the belt pressing cylinder, the belt feed can be made more stable, thereby improving the sewing quality.

[0018] 3. The auxiliary presser foot mechanism and tape cutting mechanism of this utility model can be configured on a template machine with a rotating head to improve the efficiency and accuracy of complex sewing tasks. Attached Figure Description

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-4 :

[0025] A truss formwork machine includes a machine head 1, wherein the machine head 1 is provided with:

[0026] The belt feeding mechanism 2 pulls the belt into the bowl-shaped pressure foot 31 of the auxiliary pressure foot mechanism 3. In this embodiment, the belt feeding mechanism 2 adopts a conventional mechanism in the art, such as a belt feeding mechanism 2 composed of a feeding tray, a feeding machine and a wire cylinder.

[0027] The auxiliary presser foot mechanism 3, in conjunction with the belt feeding mechanism 2, guides the belt into the cup-shaped presser foot 31. The cup-shaped presser foot 31, together with the middle presser foot, forms a pressing structure. Specifically, the auxiliary presser foot mechanism 3 includes a belt-passing cylinder 32, a belt-pressing cylinder 33, and a belt-passing head 34. The belt pulled by the belt feeding mechanism 2 passes through the belt-passing head 34. The belt-passing cylinder 32 drives the belt-pressing cylinder 33 and the belt-passing head 34 to move towards the cup-shaped presser foot 31. The piston rod of the belt-pressing cylinder 33 presses down to press the belt entering the belt-passing head 34.

[0028] Comparison Appendix Figure 1 and attached Figure 2 Initially, the belt feeder 34 is located outside the cup-shaped presser foot 31, and the piston rod of the pressing cylinder 33 is in a retracted state. In use, the belt pulled by the feeding mechanism 2 is inserted through the upper opening of the belt feeder 34 and exited through the lower opening. Then, the belt feeder cylinder 32 is activated, driving the pressing cylinder 33 and the belt feeder 34 to move towards the cup-shaped presser foot 31 until the lower opening of the belt feeder 34 carries the belt into the interior of the cup-shaped presser foot 31. Then, the pressing cylinder 33 is activated, extending its piston rod until it contacts and presses the belt. In this invention, "pressing" refers to the piston rod of the pressing cylinder 33 applying pressure, creating a dynamic constraint between the belt and the belt feeder 34.

[0029] Furthermore, refer to the appendix Figure 4 The specific installation structure of the auxiliary presser foot mechanism 3 is as follows: the belt feed cylinder 32 is mounted on the belt feed cylinder mounting plate 35, the belt feed cylinder mounting plate 35 and the cup-shaped presser foot 31 are fixed on the auxiliary presser foot rod through the auxiliary presser foot connecting plate 36, the piston rod of the belt feed cylinder 32 is connected to the belt feed head mounting plate 37 and drives it to slide relative to the belt feed cylinder mounting plate 35, the belt pressing cylinder 33 and the belt feed head 34 are both fixedly connected to the belt feed head mounting plate 37, further, the piston rod of the belt feed cylinder 32 is set upward, the belt feed head mounting plate 37 is connected to the end of the piston rod and bent downward to install the belt feed head 34.

[0030] In this embodiment, the tape feeder 34 enters the bowl-shaped presser foot 31 by oblique insertion. Specifically, the tape feeder cylinder 32, the tape feeder mounting plate 37, and the tape feeder 34 are all inclined. The tape feeder cylinder 32 drives the tape feeder 34 to move obliquely downward and insert into the bowl-shaped presser foot 31. Furthermore, the tape feeder cylinder 32, the tape feeder mounting plate 37, and the tape feeder 34 have the same inclination angle.

[0031] Preferably, the pressing cylinder 33 is arranged vertically, and an arc-shaped support plate 38 corresponding to the pressing cylinder 33 is provided at the inlet of the belt feeder 34. The piston rod of the pressing cylinder 33 cooperates with the arc-shaped support plate 38 to form a pressing structure. Furthermore, the arc-shaped support plate 38 is bent downward, and a nut or pressure plate that cooperates with the arc-shaped support plate 38 is mounted on the piston rod of the pressing cylinder 33. By setting the arc-shaped support plate 38, interference and friction when the belt enters can be avoided, and the pressing cylinder 33 can better compress the belt.

[0032] The tape cutting mechanism 4 includes a displacement cylinder 41, a tape cutting cylinder 42, and a tape cutting blade 43. The displacement cylinder 41 is located on one side of the auxiliary presser foot mechanism 3 and drives the tape cutting cylinder 42 and the tape cutting blade 43 to move between the standby position and the working position. When the tape cutting cylinder 42 and the tape cutting blade 43 move to the working position, the tape cutting blade 43 is located directly below the cup-shaped presser foot 31 and is driven by the tape cutting cylinder 42 to cut the stringer tape.

When strip cutting is required, the presser foot is lifted, and the displacement cylinder 41 drives the cutting cylinder 42 and the cutting blade 43 to move into the working position. At this time, the cutting blade 43 is located directly below the cup-shaped presser foot 31, and the fixed cutting blade 47 and the moving cutting blade 48 are located on both sides of the strip. The cutting cylinder 42 drives the moving cutting blade 48 to rotate, completing the strip cutting.

Figure 3 The specific installation structure of the tape cutting mechanism 4 is as follows: the displacement cylinder 41 is fixed to one side of the machine head 1 by the tape cutting mounting plate 44, the piston rod of the displacement cylinder 41 is connected to the tape cutting connecting plate 45, and the tape cutting cylinder 42 is installed on the tape cutting connecting plate 45; preferably, the tape cutting mounting plate 44 is set perpendicular to the machine head 1, and the displacement cylinder 41 is preferably a double-rod type cylinder; preferably, the tape cutting connecting plate 45 is an L-shaped plate and connects the displacement cylinder 41 and the tape cutting cylinder 42 respectively, and the tape cutting cylinder 42 is installed lower than the displacement cylinder 41 and the axes of the two are perpendicular.

[0035] The aforementioned tape-cutting cylinder 42 is mounted on the tape-cutting connecting plate 45 via a tape-cutting base 46. A tape-cutting fixed blade 47 is fixed on the tape-cutting base 46, and a tape-cutting moving blade 48 driven by the tape-cutting cylinder 42 is hinged thereon.

The piston rod of the tape-cutting cylinder 42 is connected to the end of the tape-cutting force through a connecting rod or other structure, and drives it to rotate around the hinge point.

[0036] In this embodiment, the tape cutting mechanism 4 enters below the bowl-shaped presser foot 31 by oblique insertion. Specifically, the tape cutting mechanism 4 is set at an angle, and the displacement cylinder 41 drives the tape cutting blade 43 to move obliquely downward and insert it directly below the bowl-shaped presser foot 31. Furthermore, the displacement cylinder 41, the tape cutting cylinder 42, and the tape cutting blade 43 have the same tilt angle.

[0037] This embodiment can be used in conjunction with a rotary template machine: the machine head 1 is equipped with a rotary head, and the auxiliary presser foot mechanism 3 and the tape cutting mechanism 4 are both mounted on the rotary head and rotate synchronously with it.
