Description

Technical Field

[0001] This utility model relates to the technical field of woven bag processing equipment, and specifically to an ultrasonic structure used for connecting inner and outer bags. Background Technology

[0002] Woven bags are plastic packaging products made using a weaving process. They can hold items and are used for packaging. With the development of technology, an inner bag is often added to the inside of the woven bag to protect items from damage during transportation. The connection between the inner bag and the outer woven bag (the outer bag) is achieved using ultrasonic bonding. The specific process involves first opening the opening of the outer bag (containing the inner bag), then placing the inner mold connected to an ultrasonic generator into the opening. Next, two outer molds are placed on the top and bottom sides of the outer bag, fitting snugly against the inner molds. The inner molds have protrusions on both sides, which act as connection points. When the ultrasonic generator operates and the inner mold vibrates, the inner bag in contact with the protrusions melts, thus connecting to the outer bag.

[0003] However, the material of the inner bag itself is relatively thin, and because the contact area is small (the contact surface is the raised end face), when it comes into contact with the raised part and melts, it creates a hole in the inner bag. The raised part will move with the vibration of the inner mold and cause the hole to enlarge, thus damaging the inner bag and making the connection between the inner and outer bags not firm. Summary of the Invention

[0004] The purpose of this invention is to provide an ultrasonic structure for connecting inner and outer bags. By setting the upper and lower sides of the inner mold end as planes, the inner bag is in contact with a plane, resulting in a large contact area. Therefore, even with vibration, the inner bag will not be damaged. At the same time, the protrusion is set on the outer mold, meaning the outer bag is in contact with the protrusion. Due to the material and thickness of the outer bag itself, and the fact that the outer mold does not vibrate, the protrusion has a relatively small impact on the outer bag, thus avoiding damage. Therefore, the above arrangement can prevent damage and ensure the stability of the connection, thereby solving the problem that protrusions on the inner mold would damage the inner bag and make the connection between the inner and outer bags not firm.

[0005] The purpose of this utility model is achieved as follows:

[0006] An ultrasonic structure for connecting inner and outer bags includes an outer mold and an inner mold, wherein the upper and lower sides of the end of the inner mold that contacts the inner bag are flat, and the outer mold includes a mounting base and a mounting plate disposed on the mounting base, wherein the mounting plate is located on the side closer to the inner mold.

[0007] The mounting plate is provided with several through holes, and a protrusion, an elastic element and a mounting element are arranged in sequence in the through holes. One end of the protrusion passes through the through hole and protrudes out. The protrusion is movable and adapts to the elastic element so that the position of the protrusion can be adaptively adjusted. The mounting element adapts to the inner wall of the through hole so as to prevent the protrusion and the elastic element from detaching from the through hole.

[0008] Preferably, the through hole includes a through section and an installation section, and the diameter of the installation section is larger than the diameter of the through section. The protrusion includes an installation block and a protrusion disposed on the installation block. The area of ​​the horizontal cross section of the protrusion is smaller than the area of ​​the horizontal cross section of the installation block. The protrusion passes through the through section and is exposed. The installation block, the elastic element, and the installation component are located inside the installation section, and the installation component is adapted to the inner wall of the installation section.

[0009] Preferably, the mounting component is threadedly connected to the inner wall of the through hole;

[0010] Alternatively, the mounting component and the inner wall of the through hole are interference fit.

[0011] Preferably, the mounting base is provided with limiting plates on both sides, and the mounting plate is located between the two limiting plates.

[0012] Preferably, a base plate is provided on one side of the outer mold, and the inner mold is connected to the ultrasonic generator and movably mounted on the base plate;

[0013] The ultrasonic generator is mounted on a movable plate, and a slider is mounted on the bottom of the movable plate and connected to a belt. The belt is connected to a drive source. A slide rail is mounted on the base plate, and the slider is located on the slide rail. The drive source drives the belt to move, thereby moving the movable plate and the slider along the slide rail.

[0014] Preferably, a base plate is provided on one side of the outer mold, and the inner mold is connected to the ultrasonic generator and movably mounted on the base plate;

[0015] The ultrasonic generator is mounted on a movable plate, and a slider is mounted on the bottom of the movable plate and connected to a belt. The belt is connected to a drive source. A slide rail is mounted on the base plate, and the slider is located on the slide rail. The drive source drives the belt to move, thereby moving the movable plate and the slider along the slide rail.

[0016] Preferably, it also includes a side plate, and a cam is connected to the bottom of the outer mold. Connectors are provided on both sides of the outer mold, and a slider three is provided on the side of the connector near the side plate. A slide rail three is provided on the side of the side plate near the connector, and the slider three is located on the slide rail three. The rotation of the cam drives the outer mold to move and drives the slider three to move along the slide rail three.

[0017] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0018] This invention sets the upper and lower sides of the inner mold end as flat surfaces, so that the inner bag is in contact with a flat surface, i.e., the contact area is large. Therefore, even if there is vibration, the inner bag will not be damaged. At the same time, the protrusion is set on the outer mold, i.e. the outer bag is in contact with the protrusion. Due to the material and thickness of the outer bag itself and the fact that the outer mold does not vibrate, the protrusion has a relatively small impact on the outer bag, thus avoiding damage to the outer bag. Therefore, the above settings can avoid damage and ensure the stability of the connection.

[0019] Meanwhile, the surface of the outer bag is not completely flat, but has certain fluctuations, and each outer bag is also processed with errors. Therefore, this utility model uses the setting of movable protrusions, so that the protrusions will adaptively adjust their position as they come into contact with the outer bag, thereby ensuring that the protrusions adhere to the outer bag without damaging it.

[0033] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0034] like Figures 1-7 As shown, the ultrasonic structure for connecting inner and outer bags includes an outer mold 1 and an inner mold 2. The upper and lower sides of the end of the inner mold 2 that contacts the inner bag are flat surfaces 21. The outer mold 1 includes a mounting base 11 and a mounting plate 12 disposed on the mounting base 11. The mounting plate 12 is located on the side closer to the inner mold 2.

[0035] Meanwhile, the mounting plate 12 is provided with a number of through holes 13, and a protrusion 14, an elastic element 15 and a mounting element 17 are arranged in sequence in the through holes 13. One end of the protrusion 14 passes through the through hole 13 and protrudes out. The protrusion 14 is movable and adapts to the elastic element 15 so that the position of the protrusion 14 can be adaptively adjusted. The mounting element 17 is adapted to the inner wall of the through hole 13 so as to prevent the protrusion 14 and the elastic element 15 from detaching from the through hole 13.

[0036] Therefore, in actual use, by setting the upper and lower sides of the inner mold 2 end as planes 21, the inner bag is in contact with a plane, that is, the contact area is large. Therefore, even if there is vibration, the inner bag will not be damaged. At the same time, the protrusion 14 is set on the outer mold 1, that is, the outer bag is in contact with the protrusion 14. Due to the material and thickness of the outer bag itself and the fact that the outer mold 1 does not vibrate, the protrusion 14 has a relatively small impact on the outer bag, thus avoiding damage to the outer bag. Therefore, the above settings can avoid damage and ensure the stability of the connection.

[0037] Meanwhile, the surface of the outer bag is not completely flat, but has certain fluctuations, and each outer bag is also processed with errors. Therefore, this utility model uses the movable protrusion 14 to make the protrusion 14 adaptively (i.e. automatically) adjust its position as it comes into contact with the outer bag, thereby ensuring that the protrusion 14 adheres to the outer bag without damaging it.

[0038] Furthermore, the specific structure of the through hole 13 and the protrusion 14 is as follows: First, the through hole 13 includes a through section 131 and a mounting section 132, and the diameter of the mounting section 132 is larger than the diameter of the through section 131. The protrusion 14 includes a mounting block 141 and a protrusion 142 disposed on the mounting block 141, and the area of ​​the horizontal cross section of the protrusion 142 is smaller than the area of ​​the horizontal cross section of the mounting block 141.

[0039] Therefore, in actual use, the protrusion 142 passes through the protrusion section 131 and is exposed, and the mounting block 141, the elastic element 15 and the mounting element 17 are located inside the mounting section 132, and the mounting element 17 is adapted to the inner wall of the mounting section 132.

[0040] Secondly, the connection between the mounting part 17 and the inner wall of the through hole 13 is varied. It can be a threaded connection, or the mounting part 17 and the inner wall of the through hole 13 can be an interference fit (an interference fit is to use the elasticity of the material to make the hole expand and deform to fit on the shaft. When the hole returns to its original state, it generates a clamping force on the shaft, so that the two parts are connected).

[0041] like Figures 1-7 As shown, the structure between the mounting base 11 and the mounting plate 12 is as follows: First, limit plates 18 are provided on both sides of the mounting base 11, and the mounting plate 12 is located between the two limit plates 18.

[0042] like Figures 1-7 As shown, the structure of the inner mold 2 is as follows: First, a base plate 3 is provided on one side of the outer mold 1, and the inner mold 2 is connected to the ultrasonic generator 4 and is movably mounted on the base plate 3.

[0043] The moving structure is as follows: First, the ultrasonic generator 4 is set on the moving plate 5, and the bottom of the moving plate 5 is provided with a slider 51 and connected to the belt 61. The belt 61 is connected to the drive source 6. The base plate 3 is provided with a slide rail 31, and the slider 51 is located on the slide rail 31.

[0044] Therefore, in actual use, the drive source 6 drives the belt 61 to move, thereby moving the moving plate 5 and the slider 51 along the slide rail 31. The drive source 6 is a motor, and the belt 61 has rollers built into both ends. One roller is connected to the drive source 6, and the other is rotatably mounted on the base plate 3 (the rotating structure can use a shaft hole fit). At the same time, the matching of the slider 51 and the slide rail 31 mainly serves to guide and limit movement.

[0045] like Figures 1-7 As shown, a spreading assembly is provided between the outer mold 1 and the inner mold 2. The spreading assembly includes a spreading member 71, a second drive source 72, a third drive source 73, a second slider 74, and a second slide rail 75. The second drive source 72 is connected to the spreading member 71 and is used to drive the spreading member 71 to rotate. The third drive source 73 is connected to the second slider 74 and is used to drive the second slider 74 to move along the second slide rail 75. The second drive source 72 is connected to the second slider 74 and moves with the second slider 74.

[0046] Therefore, in actual use, the expansion member 71 is movable and rotatable under the drive of drive source two 72 and drive source three 73. By rotating, the expansion member 71 can be rotated from the outside to the inside of the outer bag, and by moving, the expansion is achieved. Among them, drive source two 72 and drive source three 73 are both cylinders, and drive source two 72 is a rotary cylinder used to drive the rotation. The matching of slider two 74 and slide rail two 75 mainly serves as a guide and limiter.

[0047] like Figures 1-7 As shown, the structure of the outer mold 1 is as follows: First, it also includes a side plate 8, and the bottom of the outer mold 1 is connected to a cam 9. Connectors 19 are provided on both sides of the outer mold 1. A slider 191 is provided on the side of the connector 19 near the side plate 8. A slide rail 81 is provided on the side of the side plate 8 near the connector 19, and the slider 191 is located on the slide rail 81.

[0048] Therefore, in actual use, the rotation of cam 9 drives the outer mold 1 to move, which in turn drives slider 191 to move along slide rail 81. Cam 9 consists of two cams fitted with transmission components, which are connected by a connecting rod. The connecting rod is connected to the outer mold 1, so the rotation of cam 9 drives the transmission components, which in turn drives the connecting rod, thus moving the outer mold 1. Meanwhile, the matching of slider 191 and slide rail 81 mainly serves as a guide and limiter.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. However, this utility model is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model.
