Description

Technical Field

[0002] The pocket-sticking machine is mainly used to stick and sew pocket-shaped fabrics to jeans, shirts, etc. Its basic principle is to place a piece of pocket-shaped fabric on the pocket-shaped template (also called tongue plate), and use the matching die and folding knife to fold the two sides, front and two corners of the pocket-shaped fabric. During the folding process, the pocket-shaped template falls and fixes the folded pocket-shaped fabric on the work surface. Then, the folding knife is retracted and evacuated from the working area, the material receiving pressing plate moves to the top of the pocket-shaped template and presses down the folded pocket, and the pocket-shaped template performs a withdrawal action to complete the bag folding process.

[0003] In order to clamp and fix the bag-shaped fabric, an electromagnet (also called a backer) is generally set as a limiter in the die assembly. The electromagnet and the tongue plate attract each other to fix the bag-shaped fabric in the vertical direction. When the thickness of the bag-shaped fabric changes, it is usually compensated by adding a pad on the bottom side of the die. Not only is the operation cumbersome, but the pad also has the risk of warping or even falling off, and has poor adaptability to changes in fabric thickness. Utility Model Content

[0044] See also Figure 1 to Figure 4In one embodiment of the present application, an automatic adaptive adjustment mechanism for the thickness of fabric of a pocket patching machine is provided, which is used to adjust a limiter 100 that cooperates with a bag-shaped plate (not shown) in the pocket patching machine to clamp the bag-shaped fabric. The automatic adaptive adjustment mechanism includes:

[0045] A bottom plate 200, a bracket 201 is fixed on the top of the bottom plate 200;

[0046] The limiting member 100 is arranged below the bottom plate 200 in a liftable manner, and a column 101 extending upward and penetrating the bottom plate 200 is provided on the top of the limiting member 100;

[0047] The driving mechanism 300 is mounted on the bracket 201;

[0048] The transmission assembly 400 is connected between the driving mechanism 300 and the column 101 .

[0049] The automatic adaptive adjustment mechanism of the present application can achieve height adjustment of the stopper 100 through the driving mechanism 300 and the transmission assembly 400, change the relative position of the stopper 100, the bag-shaped plate and the die, and automatically adapt to the change in the thickness of the cloth. The stopper 100 itself can adopt existing technology, such as an electromagnet (also called a backer), which can attract and clamp the bag-shaped cloth with the bag-shaped plate.

[0050] In the specific implementation, referring to one embodiment, the driving mechanism 300 is a motor, and the transmission assembly 400 adopts a connecting rod 403 mechanism. The transmission assembly 400 can realize the reversal and optimized arrangement of the driving mechanism 300. For example, in the figure, the axial direction of the output shaft 401 of the motor is in the left and right direction of the bottom plate 200 (see Figure 2 The folding device is parallel to the front and rear directions, which is beneficial to control the overall volume of the folding device in the following. Figure 2 to Figure 4 , the transmission assembly 400 includes:

[0051] An output shaft 401 is connected to the main shaft of the motor;

[0052] A swing arm 402 is fixed to the output shaft 401;

[0053] The connecting rod 403 has two ends hinged between the swing arm 402 and the column 101 .

[0054] See also Figure 2The bracket 201 is provided with a transmission window 203 for avoiding the transmission assembly 400, the motor is installed on one side of the transmission window 203, and the transmission bracket is installed on the other side of the transmission window 203. The output shaft 401 extends from the motor and passes through the transmission window 203 to be assembled on the transmission bracket. The transmission bracket and the motor cooperate with each other to ensure that the output shaft 401 can withstand sufficient radial load. The transmission assembly 400 is set in the area where the transmission shaft and the transmission window 203 are aligned and penetrates the transmission window 203 to be linked with the column 101.

[0055] In the axial direction of the output shaft 401, the swing arm 402 clamps the two sides of the connecting rod 403 to achieve alignment. In the figure, the swing arm 402 and the connecting rod 403 constitute a set of swing arm mechanisms, and the axial length of the swing arm mechanism is changed by rotating the output shaft, so as to realize the lifting or lowering of the connecting seat 102, the column 101 and the limiter 100. The connecting rod 403 can directly drive the column 101, and it can also be seen from the figure that the columns 101 are arranged side by side. The two columns 101 are spaced apart in the axial direction of the output shaft 401. A connecting seat 102 is fixed between the tops of the two columns 101, and the connecting rod 403 is hinged to the connecting seat 102. In the figure, the two ends of the connecting seat 102 are fixedly connected to the two columns 101, and a hinged seat 103 is provided in the middle, and the connecting rod 403 is hinged to the hinged seat 103. The hinge of the hinge seat 103 can prevent the rotation of the connecting rod 403 from affecting the lifting and lowering of the column 101.

[0056] In the guide of column 101, see Figure 3 , the bottom plate 200 is provided with a guide hole, a guide sleeve 202 is fixed at the guide hole, and the column 101 slides through the guide sleeve 202. In the figure, an annular seat 104 is fixed at the bottom end of the column 101, and the stopper 100 is annular and the top surface is fitted and fixed with the annular seat 104; the connection position between the column 101 and the annular seat 104 is at two opposite sides of the annular seat 104 in the radial direction. In terms of overall size, the length of the connection seat 102, the diameter of the annular seat 104 and the diameter of the stopper 100 match each other.

[0057] In the stroke control of the limiter 100, the position of the limiter 100 itself can be directly detected, or it can be referred to one of the embodiments of the present application, in which a synchronizer 404 is fixed on the output shaft 401, and a sensor 405 for detecting the position of the synchronizer 404 is installed on the bracket 201. There is a corresponding relationship between the relative position of the limiter 100 and the column 101 and the rotation angle of the output shaft 401. The relative position of the limiter 100 can be detected by the synchronizer 404 and the sensor 405, and a compact layout can be achieved under the premise of ensuring the function. The synchronizer 404 is fixed on the output shaft 401 and rotates with the output shaft 401. The synchronizer 404 is arranged on the side of the transmission assembly 400 close to the motor to reduce the detection deviation caused by the torsion of the output shaft 401. The synchronizer 404 is a non-circular structure and has a triggering portion that convexes in the radial direction. The sensor 405 is arranged in the radial direction of the output shaft 401. In the axial direction of the output shaft 401, the sensor 405 and the synchronizer 404 are arranged in a staggered manner. When the output shaft 401 rotates to a preset angle, the triggering portion of the corresponding synchronizer 404 approaches and triggers the sensor 405 to achieve detection. As for each sensor itself, common types of the prior art can be used, such as travel switches, photoelectric sensors, Hall sensors, etc.

[0058] For the overall layout, see Figure 1 In the illustrated embodiment, the bracket 201 is mounted on the base plate 200 via a support column, and a plurality of support columns are provided and arranged parallel to the column 101. A containing space is formed between the bracket 201 and the base plate 200, and the column 101 and the connecting seat 102 are located in the containing space. Furthermore, a central area 105 is provided between the two columns 101, and the connecting seat 102 is a bent structure and avoids the central area 105. The connecting seat 102 is C-shaped in overall shape, and the two ends of the C-shaped opening are connected to the column 101, and the central area 105 is avoided in the C-shaped opening. The hinge seat 103 is arranged at the bottom of the C-shape. The connecting seat 102 is a plate as a whole and is arranged parallel to the base plate 200. The avoidance setting of the central area 105 can better realize the configuration of other components, such as the driving structure or transmission structure of the die assembly 500 described below.

[0059] Based on the above description, see Figure 5 , Figure 6 In one embodiment of the present application, a folding device of a pocket pasting machine is provided, including the automatic adaptive adjustment mechanism of the present application, a die assembly 500 installed on a bottom plate 200, and a bag-shaped plate cooperating with a limiting member 100.

[0060] Further, the bottom plate 200 has a central area 105, the die assembly 500 is a plurality of sets and is arranged around the central area 105, the stopper 100 is located below the central area 105 of the bottom plate 200, and the column 101 avoids the central area 105. The die assembly 500 includes a corresponding drive structure and a transmission structure, wherein the drive structure is disposed on the bracket 201, and at least a portion of the transmission structure is disposed in the central area.

[0061] Each of the concave mold assemblies 500 is provided with a unit wall 510 with adjustable position, and all the unit walls 510 together form a scalable concave mold. In this embodiment, the concave mold adopts a split structure, and the positions of the unit walls 510 can be adjusted relative to the bottom plate 200 as needed to adapt to the thickness change of the bag-shaped cloth. For example, when the thickness of the bag-shaped cloth increases, the unit walls 510 need to be relatively far away, that is, the size of the concave mold is slightly enlarged as a whole, and the unit walls 510 are locked in position after the adjustment is completed. Each unit wall 510 can be adjusted independently, and can also be adjusted in conjunction with each other.

[0062] Based on the above, one embodiment of the present application provides a pocket sticking machine, which has a folding device of the pocket sticking machine in the present application.

[0063] When the pocket sticking machine of the present application is working, if the thickness of the bag-shaped cloth changes, the driving mechanism 300 can be used to implement the action, and the swing arm 402 and the connecting rod 403 can be driven to rotate through the output shaft 401, and the above rotation is converted into the movement of the connecting seat 102 in the height direction through the hinge seat 103, and the connecting seat 102 drives the column 101 and the limiter 100 fixed to the column 101 to move, so as to adjust the limiter 100 to a suitable height. Of course, as far as the electric control method itself is concerned, conventional technology can be used, such as calculating the number of motor rotations or angles according to the change in spacing, and other structures of the pocket sticking machine can be implemented in combination with existing technologies.

[0064] The technical features of the above-mentioned embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. When the technical features in different embodiments are embodied in the same figure, it can be regarded that the figure also discloses the combination examples of the various embodiments involved.

[0065] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the scope of patent protection of the present application shall be subject to the attached claims.
