Description

Technical Field

[0001] The utility model relates to the technical field of surgical gown processing equipment, in particular to an ultrasonic spot welding machine for producing surgical gowns. Background Art

[0002] Ultrasonic spot welding machines are widely used in the production of non-woven disposable protective products. When wearing surgical gowns, they are fastened with belts. During production, the lapels and belts of surgical gowns are fixed by ultrasonic spot welding machines. When fixing the lapels and belts of surgical gowns, the operator holds the belt and extends one end under the spot welding head of the spot welding machine. The belt overlaps the lapels, and the head of the spot welding machine descends to drive the spot welding head to squeeze the spot welding table, and the fixation is completed using the ultrasonic principle.

[0003] Before spot welding, the waistband of the surgical gown has been cut into fixed lengths. When spot welding, the closer the spot welding is to the end of the waistband, the less length the waistband wastes. When aligning the ends of the waistband, the closer the alignment is to the end, the more attention needs to be paid and the more troublesome the alignment is. It is difficult to choose between saving waistband materials, shortening waistband waste length and improving spot welding efficiency. In order to reduce the difficulty of spot welding of surgical gown production waistbands and improve spot welding efficiency, a specially designed ultrasonic spot welding machine with improved structure is designed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides an ultrasonic spot welding machine for producing surgical gowns, which is used to reduce the difficulty of spot welding of waistbands in the production of surgical gowns and improve the spot welding efficiency.

[0006] An ultrasonic spot welding machine for producing surgical gowns comprises an operating table, a machine head installed on the operating table, a spot welding head installed at the bottom of the machine head, and a spot welding table installed on the operating table opposite to the spot welding head, wherein a spot welding limit seat is installed on the operating table, a clearance groove corresponding to the spot welding table is arranged in the middle of the front of the spot welding limit seat, and both sides of the clearance groove at the bottom of the front of the spot welding limit seat are provided with horizontally penetrating limit grooves, a limit pin is fixed on one side of the spot welding limit seat on the operating table, the operating table is horizontally slidably connected to the limit movable seat through the limit pin, a handle is arranged on the side of the limit movable seat away from the spot welding limit seat, a fixed seat fixed on the operating table is arranged between the limit movable seat and the spot welding limit seat, and a reset tension spring is installed between the fixed seat and the limit movable seat.

[0007] Preferably, a guiding inclined surface is provided between the front side of the spot welding limiting seat and the limiting groove.

[0008] Preferably, there are two limit pins, and two horizontal limit chutes are arranged on the limit movable seat, and the limit chutes are slidably connected with the limit pins.

[0009] Preferably, the reset tension spring is located between the two limit chutes.

[0010] Preferably, the spot welding limit seat has a left-right symmetric structure, the horizontal widths of the two limit grooves are equal, and the horizontal width of the limit groove is equal to the length of the limit chute.

[0011] Preferably, the horizontal width of the limit chute is 5-20 mm.

[0012] Preferably, the limit movable seat and the handle are of an integral structure, and anti-slip ridges are arranged on both the upper and lower surfaces of the handle.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The utility model limits the front and rear positions of the belt through the setting of the spot welding limit seat, and limits the left and right positions of the belt through the limit movable seat. During use, the operator holds both ends of the belt with both hands. The right hand is close to the right side of the spot welding limit seat and inserts the belt from front to back into the limit groove of the spot welding limit seat. The left half of the belt is directly placed on the limit movable seat. The surgical gown is laid flat on the spot welding limit seat. The left hand simultaneously holds the belt and the handle of the limit movable seat and pulls it to the left. The right end of the belt moves from right to left and approaches the spot welding table. At this time, the spot welding head descends for welding. The right end of the belt is relatively close to the spot welding position, thereby reducing the waste of belt materials. With the help of the front-back and left-right position positioning of the spot welding limit seat and the limit movable seat, the position and distance are determined and do not need to be changed or adjusted, and the technical requirements for the operator are low, and the operation is simple and efficient, so as to achieve the purpose of reducing the difficulty of spot welding the belt for the production of surgical gowns and improving the spot welding efficiency.

Specific implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figure 1-6 shown, the present invention provides a technical solution: an ultrasonic spot welder for surgical gown production, including an operating table 1, a machine head 2 installed on the operating table 1, a spot welding head 3 installed at the bottom of the machine head 2, and a spot welding table 4 installed on the operating table 1 opposite to the spot welding head 3.
