Description

TECHNICAL FIELD

[0001] The application relates to the sewing equipment technical field, in particular to a lower mold plate suction device of a bag pasting machine and the bag pasting machine. BACKGROUND

[0002] In the working process of the bag pasting machine, a bag-shaped material is laid on the lower mold plate, and then the edge folding mechanism cooperates with the lower mold plate to fold the edges of the bag-shaped material.

A magnetic suction assembly that can suction the lower mold plate is arranged below the table plate to maintain the positions of the cloth and the lower mold plate.

[0003] When the pocket shape is wide at the bottom and narrow at the top, the lower mold plate is blocked at the edge folding position of the bag-shaped material and cannot be pulled out from the pocket opening after the edge folding is completed due to the small opening at the top. In order to solve the technical problem, some lower mold plates adopt an adjustable or split structure, but the matching effect with the magnetic suction assembly below the table plate is poor, and the split feature of the lower mold plate cannot be considered. Moreover, the magnetic suction assembly may interfere with the air suction box below the table plate for suctioning the cloth, increasing the design and installation difficulty and affecting the suction positioning effect of the lower mold plate and the cloth.

Detailed Implementation

[0037] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0038] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component present. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application's specification are for illustrative purposes only and do not represent the only possible implementation.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0040] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature and the second feature are in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level (or in a usage state, or from a certain viewpoint in the drawing) than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level (or in a usage state, or from a certain viewpoint in the drawing) than the second feature.

[0041] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. The term "and / or" as used in this application includes any and all combinations of one or more of the associated listed items.

[0042] See Figures 1-3 One embodiment of this application provides a bag-applying machine, including a lower mold mechanism and a lower mold suction device that cooperate with each other. The lower mold mechanism includes a base 100, which can move vertically and / or horizontally. A lower mold 200 and a drive mechanism 300 for driving the lower mold 200 are mounted on the base 100. The lower mold 200 has a split structure, including multiple unit plates, each of which is movably fitted relative to the base 100. Specifically, the multiple unit plates include a middle plate 201 and left plates 202 and right plates 203 arranged on both sides of the middle plate 201. Here, "left" and "right" are only for ease of description and are relative concepts; either side can be the left side, and the other side the right side. The relative movement of the multiple unit plates can change the overall width of the lower mold 200 to facilitate the removal of the bag opening portion of the bag material.

[0043] In the working state, the front edges of the middle plate 201, left plate 202 and right plate 203 of the lower template 200 are connected to form a continuous extended outer contour, which corresponds to the narrowing of the bag-shaped material 400. There is a large gap between the left plate 202 and the right plate 203 to provide narrowing space. The front of the middle plate 201 is T-shaped, and the horizontal part of the T-shape is connected to the front of the left plate 202 and the right plate 203. The left plate 202 and the right plate 203 are respectively provided with avoidance areas on the opposite sides. In the narrowing state, the horizontal part of the T-shape moves relative to the left plate 202 and the right plate 203 and is located in the avoidance area, allowing the left plate 202 and the right plate 203 to move towards each other, so that the lower template 200 narrows as a whole to detach from the bag-shaped material 400.

[0044] For better compatibility with the split-type lower template 200, please refer to... Figures 4-10 One embodiment of this application discloses a lower template suction device for a bag-applying machine, including a platform 500 and a suction component 600 installed below the platform 500. A portion of the platform 500 is a suction area and has suction holes 501. The lower template 200 is movably disposed above the platform 500. The suction component 600 includes a suction box 610 for vacuum suction of fabric and a magnetic suction component for suction of the lower template 200 by electromagnetic force.

[0045] The suction box 610 is fixedly installed below the platform 500. The interior of the suction box 610 communicates with the adsorption holes 501. The suction box 610 can be an independent box or the platform 500 can serve as its top wall. In one embodiment, the side of the suction box 610 opposite to the platform 500 is a bottom plate 611. The bottom plate 611 is equipped with a connector 620 that communicates with the interior of the suction box 610 and is used to connect to an external negative pressure device. The connector 620 can be a pipe connector or other type that is easy to assemble. The negative pressure formed inside the suction box 610 can adsorb and fix the fabric to the top surface of the platform 500 in the suction area where the adsorption holes 501 are opened.

[0046] The magnetic attraction components may include multiple sets, for example, at least three sets, and are arranged below the platform 500. The embodiments below use three sets as an example, but the number is not strictly limited. Each set of magnetic attraction components includes a magnetic component for attracting the lower template 200, such as an electromagnet. The electromagnet is easy to control by an electrical signal. The magnetic component in at least one set of magnetic attraction components is located inside the suction box 610, which can reduce interference between multiple sets and between the sets and the suction box 610, and can also take into account the attraction effect on the fabric and the lower template 200.

[0047] Furthermore, the magnetic components in each set of magnetic assemblies can reciprocate and rise and fall during operation, changing the distance from the platform 500. This facilitates coordination with other magnetic devices above the lower template 200, allowing them to alternately attract the lower template 200 and change its positioning method.

[0048] Figures 7-10 As can be seen, the suction box 610 includes two spaced-apart boxes. The two suction boxes can be equipped with a base plate 611 separately or share a base plate 611. In this embodiment, the base plate 611 is shared to further simplify the structure and facilitate assembly. The part of the base plate 611 between the two suction boxes is an extension that can be used to install other components.

[0049] Each set of magnetic assemblies includes a magnetic component and a cylinder for driving the corresponding magnetic component to rise and fall. Of course, the magnetic component can also be driven to rise and fall in other ways. The three sets of magnetic assemblies are the first magnetic assembly 630, the second magnetic assembly 640, and the third magnetic assembly 650.

[0050] The first magnetic attraction component 630 is installed in one of the suction boxes, specifically including a first cylinder 631 fixed to the base plate 611 and located outside the suction box 610. The piston rod of the first cylinder 631 extends upward into the suction box 610, and a first electromagnet 632 is installed at the end of the piston rod. Based on this, the first electromagnet 632 can be raised and lowered under the drive of the first cylinder 631 to provide the expected attraction effect to the lower template 200.

[0051] The second magnetic suction assembly 640 is located between the two suction boxes and includes a second cylinder 641 fixed to the extension. The piston rod of the second cylinder 641 extends further upward and is connected to a second electromagnet 642 at its end. The second magnetic suction assembly 640 is entirely located outside the suction box.

[0052] The third magnetic suction component 650 is installed in another suction box. Its specific structure is similar to that of the first magnetic suction component 630. It includes a third cylinder 651 fixed to the base plate 611. The piston rod of the third cylinder 651 extends into the corresponding suction box and is equipped with a third electromagnet 652.

[0053] Based on the structural characteristics of the lower template 200 described above, the first electromagnet 632, the second electromagnet 642, and the third electromagnet 652 are magnetically attracted to the corresponding unit plate in the lower template 200.

[0054] See Figure 9 In one embodiment, the relative position of the piston rod of the second cylinder 641 and the connected second electromagnet 642 is adjustable. For example, the two are connected by an adjusting member 643, specifically by a plug-in or threaded connection, to change the distance between the second electromagnet 642 and the platform 500 at its extreme position. Of course, the other two sets of magnetic attraction components can also adopt a similar adjustable method, so that each electromagnet contacts the bottom surface of the platform 500 when it rises to its extreme position, so as to give full play to the magnetic attraction effect.

[0055] In different magnetic assemblies, the lifting and lowering of electromagnets can be controlled individually or moved synchronously using a unified control method. Considering the characteristics of the usage scenario, the second electromagnet 642, which is located in the center, is slightly larger in size, while the first electromagnet 632 and the third electromagnet 652, which are located on both sides, have slightly smaller diameters. For example, the outer contours of the first electromagnet 632 and the third electromagnet 652 are circular with a diameter of 20mm to 60mm, and the center distance between the first electromagnet 632 and the third electromagnet 652 is 80mm to 150mm.

[0056] When the lower template suction device of this application is working, the lower template 200 descends and stops descending when it is about to contact the top surface of the platform 500. At this time, the electromagnets in each set of magnetic suction components rise rapidly to attract and fix the corresponding unit plate to the top surface of the platform 500, ensuring the folding quality of the pocket.

[0057] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0058] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
