Description

Technical Field

[0001] The utility model relates to the technical field of bag opening machines, and specifically provides a stable bag opening machine. Background Art

[0002] The bag opening machine can make the fabric into a bag opening. After the bag opening is prepared, a zipper or bag cloth can be sewn on the bag opening. When the zipper or bag cloth needs to be sewn, the bag opening is continuously pressed by the pressing frame unit, and then the pressing frame unit is moved to the upper side of the bag cloth or zipper through the movable platform seat, so that the bag opening corresponds to the position of the zipper or bag cloth. After the bag opening corresponds to the position of the zipper or bag cloth, the height of the movable platform seat is lowered, so that the pressing frame unit presses the zipper or bag cloth from the upper side, so that the relative position of the bag opening and the zipper or bag cloth is fixed, which is convenient for further sewing.

[0003] However, the width of the bag opening is very small, so when sewing the zipper or bag cloth, the position accuracy of the bag opening and the zipper or bag cloth is required to be high. The frame pressing unit is usually suspended on the upper side of the working platform of the bag opener. After long-term use, the mobile platform seat and the frame pressing unit are prone to tilting and other problems due to overloading, resulting in an angular offset of the frame pressing unit. The angular offset of the frame pressing unit will further cause the position of the bag opening fixed by the frame pressing unit to shift. The position offset of the bag opening will cause the sewing position with the zipper or bag cloth to shift, resulting in unqualified products. Therefore, the problem of overloading between the frame pressing unit and the mobile platform seat needs to be solved urgently. Utility Model Content

[0004] The utility model provides a stable bag opening machine, which is used to solve the problem of uneven load of a pressing frame unit when it is used for a long time.

[0005] The technical solution of the utility model is as follows:

[0006] A stable bag opening machine includes a frame, a mobile platform seat, a frame pressing unit and an x-axis module, wherein the frame is provided with a working platform, the x-axis module is provided on one side of the working platform, the mobile platform seat is provided on one side of the working platform, one side of the mobile platform seat is connected to the x-axis module by transmission, and the frame pressing unit is connected to the mobile platform seat. With the offset design, the weight of the frame pressing unit is more distributed to the mobile platform seat.

[0007] In the present solution, since the movable platform seat is arranged on one side of the working platform, the weight of the movable platform seat itself can be used to balance the off-load of the frame pressing unit, which is equivalent to the frame pressing unit and the movable platform seat being off-loaded to both sides of the x-axis module at the same time, with the off-load directions being opposite, thereby reducing the off-load of the frame pressing unit, thereby improving the stability of the movable platform seat and the frame pressing unit during movement, avoiding the deflection of the frame pressing unit, and improving the accuracy of the frame pressing unit.

[0008] The x-axis module is arranged on the side of the working platform, and one side of the moving platform seat is connected to the x-axis module.

[0033] In conjunction with the accompanying drawings, the technical solution of the present utility model is clearly and completely explained through the specific implementation methods of the embodiments of the present utility model.

[0034] Embodiment 1.

[0035] like Figure 1 As shown, the first embodiment provides a stable bag opening machine, including a frame, a mobile platform seat 1, a pressing frame unit 2 and an x-axis module 3. The frame is provided with a working platform 7, and the top surface of the working platform 7 is a plane, which can be used to lay cloth. The x-axis module 3 is arranged on the working platform 7, and the mobile platform seat 1 is connected to the x-axis module 3, so that the mobile platform seat 1 can move along the direction of the x-axis module 3. The pressing frame unit 2 is installed on the mobile platform seat 1, and the mobile platform seat 1 is used to support the pressing frame unit 2 and carry the pressing frame unit 2 to move relative to the working platform 7. The center of gravity of the pressing frame unit 2 and the mobile platform seat 1 are respectively located on both sides of the x-axis module 3, so that the eccentric load generated after the pressing frame unit 2 and the mobile platform seat 1 are connected can balance the eccentric load state of the pressing frame unit 2, so that the eccentric load of the pressing frame unit 2 is balanced, so that the pressing frame unit 2 will not have the problem of angle deviation under long-term working conditions.

[0036] The x-axis module 3 is arranged on the side of the working platform 7, and the side of the mobile platform seat 1 is connected to the x-axis module 3. It is equivalent to that the side of the mobile platform seat 1 is indirectly connected to the side of the working platform 7. The side connection method can make the height of the mobile platform seat 1 more flexibly set relative to the height of the working platform 7. In other words, the height of the mobile platform seat 1 can be lower, so as to facilitate the installation of other structures of the bag opening machine. For example, if structures such as sewing machine heads and cutting machine heads need to be installed on the top of the frame, the lower the height of the mobile platform seat 1 is, the more likely it is that the mobile platform seat 1 will block other structures. At the same time, the side of the mobile platform seat 1 is indirectly connected to the side of the working platform 7, so that the top surface of the mobile platform seat 1 can be flush with the top surface of the working platform 7. When the pressing frame unit 2 is connected to the mobile platform seat 1, the bottom surface of the pressing frame unit 2 can be flush with the top surface of the working platform 7, which is convenient for the installation and setting of the pressing frame unit 2.

[0037] The frame includes a support leg 5 and a column 4, the bottom end of the column 4 is connected to the support leg 5, and the working platform 7 is connected to the column 4. The working platform 7 includes four sides, which are divided into two long sides and two end sides according to different lengths. The x-axis module 3 is connected to a long side, and the x-axis module 3 can drive the mobile platform seat 1 to move along the length direction of the long side. The short side of the working platform 7 is connected to the column 4. The two sides of the working platform 7 are respectively connected to two columns 4, and the working platform 7 is fixed by the support of the columns 4 on both sides.

[0038] One end of the short side of the working platform 7 is connected to the column 4. Of the two long sides, the x-axis module 3 is located on the side close to the column 4. Since the x-axis module 3 is connected to the mobile platform seat 1, under the action of the gravity of the mobile platform seat 1, the total center of gravity of the working platform 7, the mobile platform seat 1 and the pressing frame unit 2 can be maintained between the two columns 4, avoiding the shift of the center of gravity of the working platform 7. The setting method of installing the working platform 7 with a forward offset can avoid the mobile platform seat 1 causing the front and rear dimensions of the entire bag opener to be too large. Therefore, the position of the working platform 7 is offset to the front side, and after the mobile platform seat 1 is installed, it will not cause the center of gravity of the entire bag opener to shift backward.

[0039] The x-axis module 3 includes a servo motor, a screw nut, a guide rail and a slider. The screw is rotatably connected to the side of the working platform 7. The guide rail is fixed to the side of the working platform 7 by a fastener. The nut is in driving cooperation with the screw. The nut is connected to the mobile platform seat 1. The slider is slidingly cooperated with the guide rail. The slider is fixedly connected to the mobile platform seat 1. The servo motor is in driving connection with the screw. The servo motor provides power for the rotation of the screw. The screw nut is used to convert the power into the moving power of the mobile platform seat 1. The guide rail is used to constrain the moving direction of the mobile platform seat 1. The direction of the guide rail is set along the length direction of the working platform 7, so that the mobile platform seat 1 can move horizontally along the length direction of the working platform 7.

[0040] The column 4 is provided with a mounting hole 6, and the servo motor is arranged in the mounting hole 6. The mounting hole 6 is used to accommodate the servo motor, so the servo motor is not on the side of the working platform 7, and thus will not hinder the movement of the mobile platform seat 1, ensuring that the mobile platform seat 1 can move to both ends of the working platform 7, so that the pressing frame unit 2 can move to both ends of the top surface of the working platform 7, so that the top surface of the working platform 7 is fully utilized.

[0041] The mobile platform seat 1 includes a first connecting plate, a second connecting plate, a third connecting plate, a z-axis module and a y-axis module. The first connecting plate is connected to the x-axis module 3, and the first connecting plate is vertically arranged. The first connecting plate is provided with a z-axis module, and the second connecting plate is connected to the z-axis module. Under the action of the z-axis module, the second connecting plate can be lifted up and down. The second connecting plate is provided with a y-axis module, and the third connecting plate is connected to the y-axis module. The second connecting plate is an L-shaped plate, including a vertical part and a horizontal part. The vertical part of the second connecting plate is connected to the z-axis module, the horizontal part of the second connecting plate is provided with a y-axis module, the third connecting plate is connected to the y-axis module, and the third connecting plate is horizontally arranged. The third connecting plate is fixedly connected to the pressing frame unit 2.

[0042] The first connecting plate, the second connecting plate and the third connecting plate may be replaced by a frame formed by profiles.

[0043] The z-axis module shown may include a lead screw nut, a guide rail and a slider, and the y-axis module shown may also include a lead screw nut, a guide rail and a slider. The lead screw and the guide rail of the z-axis module are arranged vertically, while the lead screw and the guide rail of the y-axis module are arranged horizontally, and the lead screw and the guide rail of the y-axis module are perpendicular to the lead screw and the guide rail of the x-axis module 3.
