[0006] Preferably, the inner part of the outer frame fixing plate is provided with the inner frame left-right displacement fixing plate; the surface of the inner frame left-right displacement fixing plate is provided with a plurality of flange fixing plates at equal intervals; the surface of the flange fixing plate is fixedly installed with the ultrasonic welding system; and the side of the outer frame fixing plate is provided with the left-right movable adjusting cylinder.

[0007] Preferably, each adjustable positioning baffle is fixed by left and right two bending plates.

[0008] Compared with the prior art, the present application has the following beneficial effects:

[0009] Based on the diameter and height of the bagged spring strips, set the positions of the adjustable positioning baffle and ultrasonic welding system, as well as the position and height of the adjustable welding pins. Simultaneously, adjust and fix the position of the adjustable positioning baffle and the lateral displacement distance of the ultrasonic welding mechanism and welding pin fixing plate according to the diameter of the bagged spring strips. This device is a bed net formed by welding bagged spring strips row by row. Each row of bagged spring strips requires staggered welding; that is, the first and second rows of bagged spring strips are welded by the ultrasonic welding mechanism at the odd-numbered intervals of the 1st, 3rd, and 5th rows of bagged spring strips, and the second and third rows are welded by the ultrasonic welding mechanism at the even-numbered intervals of the 2nd, 4th, and 6th rows. At the intervals between the first, third, and fourth rows of bag spring strips, the third and fourth rows are welded to the odd-numbered intervals between the first, third, and fifth bag spring strips, and so on in a staggered welding cycle. After the first and second rows of bag spring strips are welded in their positions, the adjustable welding pin rises to the top and moves left and right by the originally set distance to the next row to be welded. At the same time, under the action of the ultrasonic fixing and motion mechanism, the ultrasonic welding system pushes back to its original position and also moves left and right by the originally set distance to the next row to be welded. The welded bag spring strip is then pushed forward to the welding position by the action of the adjustable positioning baffle (according to the bag spring). After determining the diameter of the spring strip, the adjustable positioning baffle retracts to its original position to equip the welding of the next row of bag spring strips. When the next bag spring strip is placed in the welding position, the adjustable welding pin passes through the unwelded gap holes of the first and second rows of bag spring strips (a hole will be formed at the unwelded gap of the 2nd, 4th, and 6th springs after welding the 1st, 3rd, and 5th gaps of the first and second rows of bag springs) to the base plate of the welding pin. The positioning baffle pushes the bag spring strip to be welded forward, and the adjustable welding pin clamps the two bag spring strips in position. Under the action of the ultrasonic fixing and motion mechanism, the ultrasonic welding system also moves forward. The ultrasonic mold passes through the middle of the positioning baffle and presses the non-woven fabric between the two pocket spring strips onto the side of the welding pin for ultrasonic welding. Each welding position is vertically fixed by two sets of high-frequency ultrasonic welding mechanisms. The bottom ultrasonic welding mechanism is fixed, while the top ultrasonic welding mechanism is height-adjustable and can be adjusted according to the height of the pocket spring strips. When welding shorter pocket spring strips, the top ultrasonic welding mechanism can be disassembled. This method replaces the traditional method of arranging and gluing several independent pocket spring strips together with hot melt adhesive to form a bed net. It is not only simple and convenient to operate, but also structurally strong and meets energy-saving and environmental protection requirements. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-6This invention provides an ultrasonic welding device for mattress pocket springs, comprising a device body 1. The device body 1 includes an ultrasonic fixing and moving mechanism 2, a pocket spring positioning baffle moving mechanism 3, an ultrasonic welding mechanism 4, a welding positioning pin baffle bracket 5, a welding pin base plate 6, pocket spring strips 8, a traction conveyor belt 7, and a welding pin upper bracket mechanism 9. The welding pin upper bracket mechanism 9 is located at the middle of the top of the welding positioning pin baffle bracket 5, the welding pin base plate 6 is located at the bottom of the welding positioning pin baffle bracket 5, a pocket spring strip 8 is located on one side of the top of the welding pin base plate 6, and the traction conveyor belt 7 is located on one side of the welding positioning pin baffle bracket 5. A bag spring placement platform is provided on the side of the insertion pin baffle bracket 5 away from the traction conveyor belt 7. A bag spring positioning baffle motion mechanism 3 is provided on the front of the bag spring placement platform. An ultrasonic welding mechanism 4 is provided in the inner cavity of the bag spring positioning baffle motion mechanism 3. An ultrasonic fixing and motion mechanism 2 is provided on the front of the bag spring positioning baffle motion mechanism 3. The bag spring positioning baffle motion mechanism 3 includes a bag spring positioning baffle bracket 31, a positioning baffle fixing plate 32 and an adjustable positioning baffle 33. The ultrasonic welding mechanism 4 includes an outer frame fixing plate 41, an inner frame left and right displacement fixing plate 42, a flange fixing plate 43, an ultrasonic welding system 44 and a left and right movable adjustment cylinder 45.

[0019] In use, first, the positions of the adjustable positioning baffle 33 and the ultrasonic welding system 44, as well as the position and height of the adjustable welding pin 91, are set according to the diameter and height of the bag spring strip 8. At the same time, the distance between the left and right displacements of the adjustable positioning baffle 33, the ultrasonic welding mechanism 4, and the welding pin fixing plate 92 should be adjusted and fixed according to the diameter of the bag spring strip 8. The device is a bed core formed by welding bag spring strips 8 row by row. Each row of bag spring strips 8 needs to be welded in a staggered manner. That is, the first and second rows of bag spring strips are welded by the ultrasonic welding mechanism 4 at the odd-numbered intervals of the 1st, 3rd, and 5th bag spring strips 8. The second and third rows of bag spring strips 8 are welded by the ultrasonic welding mechanism 4 at the even-numbered intervals of the 2nd, 4th, and 6th bag spring strips 8. The third and fourth rows of bag spring strips 8 are welded again at the odd-numbered intervals of the 1st, 3rd, and 5th bag spring strips 8. This staggered welding is repeated in a cyclical manner.

[0020] The welding pin support mechanism 9 includes adjustable welding pins 91, welding pin fixing plate 92, a row of welding pins left and right displacement mechanism 93, and welding pin support 94. Both ends of the top of the welding pin support 94 are provided with the row of welding pins left and right displacement mechanism 93, and the bottom of the welding pin support 94 is provided with the welding pin fixing plate 92. Several adjustable welding pins 91 are provided at the bottom of the welding pin fixing plate 92.

[0021] In use, it is used to fix the adjustable welding pin 91, so that the adjustable welding pin 91 can be raised and lowered as a whole, and the welding pin fixing plate 92 can be moved left and right.

[0022] Both ends of the positioning baffle fixing plate 32 are fixedly connected to the bag spring positioning baffle bracket 31, and several adjustable positioning baffles 33 are equidistantly arranged on the front of the positioning baffle fixing plate 32.

[0023] In use, push the row of bag spring strips 8 placed in front of the adjustable positioning baffle 33 forward horizontally to the welding position and clamp the two rows of bag spring strips 8 non-woven fabrics together with the adjustable welding pins 91. After welding, push the bag spring strips 8 at the welding position forward.

[0024] The inner frame fixing plate 42, which can move left and right, is provided inside the outer frame fixing plate 41. Several flange fixing plates 43 are equidistantly arranged on the surface of the inner frame fixing plate 42. An ultrasonic welding system 44 is fixedly installed on the surface of the flange fixing plate 43. A left and right movable adjusting cylinder 45 is provided on the side of the outer frame fixing plate 41.

[0025] In use, the ultrasonic welding mechanism 4, under the action of the ultrasonic fixing and moving mechanism 2, pushes each ultrasonic welding system 44 from the middle of each adjustable positioning baffle 33 and presses the two rows of bagged spring strips 8 vertically and horizontally against the side of the adjustable welding pin 91 for ultrasonic welding.

[0026] The ultrasonic welding system 44 passes through the inner cavity of the adjustable positioning baffle 33.

[0027] When in use, it acts as a barrier during ultrasonic welding, preventing the ultrasonic welding system 44 from tearing the protective cloth during welding.

[0028] Each adjustable positioning baffle 33 is fixed by two curved plates on the left and right sides.

[0029] In practical use, firstly, based on the diameter and height of the bag spring strip 8, set the positions of the adjustable positioning baffle 33 and the ultrasonic welding system 44, as well as the position and height of the adjustable welding pin 91. Simultaneously, adjust and fix the lateral displacement spacing of the adjustable positioning baffle 33, the ultrasonic welding mechanism 4, and the welding pin fixing plate 92 according to the diameter of the bag spring strip 8. This device is a bed core formed by welding bag spring strips 8 row by row. Each row of bag spring strips 8 needs to be staggered during welding; that is, the first and second rows of bag spring strips 8 are welded by the ultrasonic welding mechanism 4 at the odd-numbered intervals of the 1st, 3rd, and 5th bag spring strips 8, and the second and third rows are welded by staggered welding. The bag spring strips 8 are welded to the even-numbered intervals of the 2nd, 4th, and 6th rows of bag spring strips 8 by the ultrasonic welding mechanism 4. The third and fourth rows of bag spring strips 8 are then welded to the odd-numbered intervals of the 1st, 3rd, and 5th rows of bag spring strips 8, and so on in a staggered cyclic welding manner. After each row of ultrasonic welding is completed, a through hole is created at the interval of the unwelded bag spring strips 8. The through hole formed between the four circular bag springs is used to insert the adjustable welding pin 91 when welding from the second row onwards. When the next row of bag spring strips 8 is pushed in horizontally and vertically by the adjustable positioning baffle 33, the bag spring positioning baffle movement mechanism 3 will push it horizontally forward.

[0030] The adjustable welding pin 91 tightens the two rows of pocket spring strips 8 that need to be welded; under the action of the ultrasonic fixing and moving mechanism 2, each ultrasonic welding system 44 is pushed from the middle of each adjustable positioning baffle 33 and presses the two rows of pocket spring strips 8 vertically and horizontally on the side of the adjustable welding pin 91 for ultrasonic welding. This replaces the traditional method of arranging and gluing several independent pocket spring strips 8 into a bed net by hot melt adhesive. It is not only simple and convenient to operate, but also has a strong structure and meets the requirements of energy saving and environmental protection.

[0031] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
