[0002] Gauze is a kind of cotton fabric with sparse warp and weft. It belongs to textile raw materials, cloth, and is characterized by sparseness and obvious grids. Degreased gauze is mainly used for medical gauze. Medical gauze is a wound dressing product, used to cover sores, wounds or other damaged medical materials. Medical gauze is the earliest and most widely used type of dressing. Its advantages are strong and rapid absorption of wound exudate and relatively simple production and processing.

[0003] Gauze needs to be folded, packaged and other steps during processing. With different medical needs, gauze packaging requires plastic packaging, and plastic packaging requires a blister packaging machine. The height of the existing blister packaging machine is fixed, and it is difficult to adjust the height of the blister packaging machine. The height of the operators operating the blister packaging machine is different, which causes inconvenience to operators who are too high or too short relative to the operating platform of the blister packaging machine, affecting the packaging of gauze. In addition, the existing blister packaging machine needs to add a supporting and fixing device during use to ensure the stability of the blister packaging machine. When the blister packaging machine needs to be transferred to other designated locations during actual use, it is necessary to carry or hoist the blister packaging machine onto a transfer device before transfer. This method not only increases the labor intensity of the operator, but also has low efficiency. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1-3 As shown, an embodiment of the utility model discloses a blister packaging machine, comprising a packaging machine body 1, a hollow mounting block 2 is arranged below the packaging machine body 1, and a lifting mechanism for lifting the packaging machine body 1 in the vertical direction is arranged in the mounting block 2; the lifting mechanism comprises a driving motor 20 and a bidirectional screw rod 21, one end of the bidirectional screw rod 21 is fixed to an inner side wall of the mounting block 2 through a bearing seat, and the other end of the bidirectional screw rod 21 passes through the other inner side wall of the mounting block 2 and extends to the outside of the mounting block 2 and is connected to the power output shaft of the driving motor 20; both ends of the bidirectional screw rod 21 are respectively provided with threaded sleeves 22 through threaded engagement, and the tops of the two threaded sleeves 22 are both hinged to one end of a first connecting rod 23, and the other end of the first connecting rod 23 passes through the top of the mounting block 2 and is hinged to the bottom of the packaging machine body 1; the bottoms of the threaded sleeves 22 are both hinged to one end of a second connecting rod 24, and the other end of the second connecting rod 24 is hinged to the inner bottom of the mounting block 2;

[0021] Through the above arrangement, the present embodiment can realize that by starting the driving motor, the power output shaft of the driving motor rotates forward or reversely to drive the bidirectional screw to rotate synchronously. The rotation of the bidirectional screw causes the two threaded sleeves to move toward each other or move away from each other on the bidirectional screw. When the two threaded sleeves move toward each other, the blister packaging machine body is driven to move vertically downward as a whole; when the two threaded sleeves move in the opposite directions away from each other, the blister packaging machine body is driven to move vertically upward; thereby, the height of the blister packaging machine is adjusted, so that the blister packaging machine of the present embodiment can be adapted for use by operators of different heights.

[0022] In this embodiment, two support plates 25 are symmetrically fixed on both sides of the lower side of the packaging machine body 1, the inner wall surface of the mounting block 2 is provided with a limiting slide groove 26 distributed along the longitudinal direction, and a limiting slider 250 slidably connected to the limiting slide groove 26 is fixed on the surface of the support plate 25.

[0023] Through the above arrangement, the limiting slider in this embodiment can be embedded in the limiting slide groove and can slide along the length direction of the limiting slide groove, thereby driving the support plate and the packaging machine body connected to the support plate to move up and down more smoothly.

[0024] In this embodiment, a notch 251 is formed on the bottom surface of the two support plates 25 , and the width of the notch 251 is greater than the diameter of the bidirectional screw rod 21 .

[0025] The embodiment can ensure that the two ends of the bidirectional screw rod pass through the two support plates respectively through the above arrangement, and can be embedded to avoid the bidirectional screw rod blocking the support plates and affecting the height adjustment of the blister packaging machine.

[0026] It is further explained that a movable support seat 3 is arranged below the mounting block 2, and the mounting block 2 is fixedly arranged on the top of the movable support seat 3; two fixed blocks 30 are arranged inside the movable support seat 3, and a dual-axis motor 31 is fixedly installed on the top of the fixed block 30, and a screw rod 32 rotatably connected to the inner walls on both sides of the movable support seat 3 is fixedly installed on the output shaft of the dual-axis motor 31, and two movable blocks 33 are threadedly connected to the outer side of the screw rod 32, and a spring 34 is fixedly installed on the inner bottom wall of the movable support seat 3, and a mounting plate 35 is fixedly installed on the top of the spring 34, and a connecting rod 36 hinged to the movable block 33 is hinged on the top of the mounting plate 35, and a universal wheel 37 is installed on the bottom of the mounting plate 35.

[0027] The above arrangement of this embodiment can realize that by starting the double-axis motor, the double-axis motor drives the screw rod to rotate, and the rotation of the screw rod causes the movable block outside the screw rod to move toward each other and squeeze the connecting rod. After the connecting rod is squeezed, it drives the universal wheel at the bottom of the mounting plate to slowly extend to the bottom of the mobile support seat, and separates the mobile support seat from the ground. At this time, the mounting block above the mobile support seat and the packaging machine body on the top of the mounting block are supported by the universal wheel. Due to the provision of the universal wheel, the mobile support seat can be pushed at this time, so as to realize the movement of the blister packaging machine body to the desired position and realize the transportation of the blister packaging machine. After the blister packaging machine is transferred to the designated position, the dual-axis motor is started again to drive the dual-axis motor to reverse the screw rod. The reverse rotation of the screw rod causes the movable block outside the screw rod to move backward and pull the connecting rod upward. After the connecting rod is pulled upward, it drives the universal wheel at the bottom of the mounting plate to move upward and retract to the inside of the mobile support seat, so that the bottom of the mobile support seat contacts the ground. At this time, the mounting block above the mobile support seat and the packaging machine body on the top of the mounting block are supported by the mobile support seat. Since the bottom of the mobile support seat contacts the ground, the contact area between the device as a whole and the ground is increased, so that the whole formed by the blister packaging machine and the mounting block can be stably supported. Therefore, the mobile support seat provided in this embodiment can realize the dual purpose of supporting and transporting the blister packaging machine.

[0028] In this embodiment, two opposite thread grooves are formed on the outer side of the screw rod 32 , and thread holes corresponding to the opposite thread grooves are formed inside the movable block 33 .

[0029] The above arrangement of this embodiment can facilitate the movable block to move toward or away from the screw rod through the opposite thread grooves and thread holes.

[0030] In this embodiment, a first sliding groove is provided on the inner wall of the movable support seat 3 and the opposite side of the fixed block 30 , and the mounting plate 35 is slidably connected with the movable support seat 3 and the fixed block 30 through the first sliding groove.

[0031] The above arrangement in this embodiment can facilitate the stable up and down movement of the mounting plate inside the movable support seat through the first sliding groove.

[0032] In this embodiment, a through slot is provided at the bottom of the movable support seat 3 , and the position of the through slot corresponds to the position of the universal wheel 37 .

[0033] The above arrangement of this embodiment can facilitate the universal wheel to extend to the bottom of the movable support seat through the through slot, thereby facilitating the movement of the blister machine on the top of the movable support seat.

[0034] Finally, it should be noted that the above only describes in detail the specific embodiments of the utility model. However, the utility model is not limited to the specific embodiments described above. Equivalent modifications and substitutions made by technicians in this field to the utility model are also within the scope of the utility model. Therefore, equal changes and modifications made without departing from the spirit and scope of the utility model are all included in the scope of the utility model.
