DETAILED DESCRIPTION

[0029] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0030] The present invention discloses a fully automatic bandage packaging machine, such as Figure 1 As shown, it includes a fixed seat 1, on the upper surface of which a lateral support frame 2 is fixedly installed, on which and along the bandage guiding direction, there are arranged in sequence an unwinding wheel 3 for unwinding the bandage, a deviation correction component 4 for correctly guiding the bandage, an ironing component 5 for hot pressing and ironing the bandage, a cutting component 6 for cutting the bandage, a packaging component 7 for packaging the cut bandage, and a blister component 8.

[0031] like Figure 1 As shown, after the bandage goes through the processes of unwinding, correcting deviation, ironing, cutting, packaging, and blister packaging in sequence, the full automation operation greatly improves the production efficiency, can process a large number of bandages in a short time, and reduce labor costs; and the precise coordination of various components can ensure the accuracy of bandage cutting and packaging, reducing human errors.

[0032] like Figure 1 As shown, a swing rod 9 and a first hydraulic rod 10 are provided on the lateral support frame 2, one end of the swing rod 9 is hingedly arranged with the lateral support frame 2, the output end of the first hydraulic rod 10 is hingedly arranged with the bottom of the swing rod 9, the unwinding wheel 3 is rotated on the other end of the swing rod 9, and the swing rod 9 is rotated with the lateral support frame 2 through the first hydraulic rod 10, thereby adjusting the angle of the unwinding wheel 3 on the swing rod 9. like Figure 1 As shown, the output end of the first hydraulic rod 10 is fixed at the bottom of the rocker arm 9. When the hydraulic rod is extended or retracted, the rocker arm 9 is pushed to rotate at the hinge point. By controlling the extension or retraction of the first hydraulic rod 10, the inclination angle of the rocker arm 9 can be changed within a certain range, thereby adjusting the position and angle of the unwinding wheel 3. The angle adjustment of the unwinding wheel 3 can help optimize the unwinding and guiding of the bandage, ensure the smoothness of the bandage during the unwinding process, reduce the risk of blockage and deviation of the rope, and thus improve production efficiency.

[0033] like Figure 1As shown, the deviation correction component 4 includes an inclined support frame 401 arranged on the upper surface of the fixed seat 1, the bottom of the inclined support frame 401 is fixedly connected to the upper surface of the fixed seat 1, and the top of the inclined support frame 401 is provided with an arc guide surface 402. The arc guide surface 402 formed on the top of the inclined support frame 401 enables the bandage to be well supported and guided when passing through; two limiting wheels 403 are provided on the inclined support frame 401, and the two limiting wheels 403 are respectively located on both sides of the arc guide surface 402 of the inclined support frame 401, and a space is formed between the two limiting wheels 403 and the arc guide surface 402. The guide portion 403 is formed into a guide portion for the bandage to pass through, and the guide portion provides a clear path to ensure that the bandage can move stably along the predetermined direction; when the bandage passes through, the existence of the limiting wheel 403 can limit the deviation of the bandage to ensure that it always remains on the ideal motion trajectory; the combination of the limiting wheel 403 and the arc guide surface 402 provides a strong guiding ability, so that the bandage is not easy to deviate during the transmission process, thereby ensuring the operation stability of the equipment; by optimizing the movement path of the bandage, the friction between the bandage and other components is reduced, thereby reducing the risk of wear and damage and extending the service life of the bandage and the equipment.

[0034] like Figure 1 As shown, the ironing assembly 5 includes a guide roller 501 and a heating roller 502 arranged on the lateral support frame 2, wherein two guide rollers 501 are arranged up and down, and the bandage after deviation correction passes through the two guide rollers 501, and the two guide rollers 501 are arranged up and down to form a clamping mechanism, which can guide the bandage to pass between the two rollers; through the design of the guide roller 501, the bandage always remains in a predetermined position when passing through, preventing it from shifting during the heating process, thereby ensuring the consistency of ironing; the heating roller 502 is a component used to apply heat to the bandage, and the roller 502 body is heated by electric heating so that its surface temperature reaches the standard of effective ironing; when the bandage moves between the guide rollers 501, it is close to the surface of the heating roller 502, and the heat transfer makes the fiber structure of the bandage relax, thereby achieving the effect of ironing; through the synergistic effect of the guide roller 501 and the heating roller 502, the wrinkles and unevenness of the bandage can be effectively reduced, ensuring its quality in subsequent processes.

[0035] like Figure 1As shown, the cutting assembly 6 includes a mounting side frame 601, on which a movably arranged tensioning shaft 602, a positioning shaft 603 and a cutting shaft 604 are provided. The bandage is stretched straight at the tensioning shaft 602, and the setting of the tensioning shaft 602 applies tension to the bandage to ensure that it remains straight during the unwinding process to prevent wrinkles or loosening; this provides a stable working condition for subsequent cutting; during the continuous unwinding process, the setting of the positioning shaft 603 ensures that the bandage is in a correct and fixed position during cutting, thereby avoiding cutting errors caused by the movement of the bandage; this mechanism ensures the consistency of the size of each cut; the positioning effect is achieved at the positioning shaft 603, and a slidable The invention relates to a movable cutter head, wherein the driving end of the cutter head is connected to a driving component, and the slidable design of the cutter head allows it to adjust its position as needed during the cutting process to adapt to bandages of different sizes; the cutter head realizes the cutting action through the connected driving component, and when receiving a control signal, the driving component enables the cutter head to cut the bandage according to a preset trajectory; the driving component provides power to the cutter head, so that the cutting process can be automated; by controlling the driving component, the cutting timing and thickness can be accurately adjusted to ensure that the bandage is cut to the required accurate size; the above scheme adopts an automated cutting process to reduce the need for manual operation and improve the production speed; combined with the design of the adjustable cutter head, it can quickly respond to different bandage specifications and improve the flexibility and efficiency of production.

[0036] like Figure 1 and Figure 2 As shown, the packaging assembly 7 includes a cross bar 701 fixed on the mounting side frame 601, the cross bar 701 is located directly below the cutter head, and a negative pressure port 702 for generating negative pressure is provided on the cross bar 701. The negative pressure generated in the negative pressure port 702 allows the cut bandage to be quickly guided to the position of the cross bar 701. When the bandage is cut by the cutting device, it will fall in the air due to the action of the cutter head; the presence of the negative pressure port 702 will form an attraction at the position of the cross bar 701, which will quickly attract and guide the fallen bandage to the position of the cross bar 701.

[0037] like Figure 2As shown, a longitudinal guide block 703 is provided at the bottom of the cross bar 701, and an arc surface 704 is provided on the upper surface of the longitudinal guide block 703. The arc surface 704 provides a smooth transition surface, so that the object can pass through the guide block more smoothly and reduce friction and jamming; and the upper surface of the cross bar 701 is tangent to the top of the arc surface 704 of the longitudinal guide block 703, and limiting baffles 705 are provided on both sides of the longitudinal guide block 703. A guide channel is formed between the two limiting baffles 705 and the arc surface 704 on the longitudinal guide block 703. The setting of the guide channel can limit the movement direction of the bandage and ensure that the bandage moves along a predetermined trajectory; when the bandage or other materials pass through the guide channel, the existence of the limiting baffle 705 can further enhance the stability of the material during the guiding process, while avoiding deviations caused by swinging or improper movement.

[0038] like Figure 1 , Figure 2 and Figure 3 As shown, the blister assembly 8 includes a base plate 801, a lower bracket 802, an upper bracket and a hot pressing piece 803, an upper plastic patch 804 is arranged in the upper bracket, a lower plastic patch 805 is arranged on the lower bracket 802, a negative pressure groove 806 for generating negative pressure is arranged inside the base plate 801, and the lower plastic patch 805 is located directly above the negative pressure groove 806. Through the negative pressure in the negative pressure groove 806, the lower plastic patch 805 is deformed downward and adheres to the inner surface of the negative pressure groove 806 to form a packaging groove 807, and the cut bandage is guided to the inside of the packaging groove 807 through the guide channel, and moves downward through the hot pressing piece 803, and hot presses the upper plastic patch 804, so that the upper plastic patch 804 and the lower plastic patch 805 form a whole at the position of the packaging groove 807.

[0039] like Figure 1 , Figure 2 and Figure 3As shown, inside the bottom plate 801 of the plastic suction component 8, there is a negative pressure groove 806. Through the generation of negative pressure, the lower plastic patch 805 is attracted by the negative pressure below, causing it to deform downward. When the lower plastic patch 805 deforms downward and closely adheres to the inner surface of the negative pressure groove 806, a preliminary packaging groove 807 is formed. This packaging groove 807 is used to hold the bandage to be loaded. The cut bandage is accurately introduced into the formed packaging groove 807 through the guiding channel. The design of the guiding channel ensures the precise positioning of the material and avoids deviation during the transfer process. When the hot pressing part 803 moves downward, the temperature of the upper plastic patch 804 is increased by heating, promoting its adhesion to the lower plastic patch 805. During the hot pressing process, the upper plastic patch 804 and the lower plastic patch 805 form a sealed whole at the position of the packaging groove 807, completing the encapsulation of the bandage. The combination of negative pressure and hot pressing can achieve fast and accurate encapsulation, improve production efficiency, and is suitable for large-scale automated production.

[0040] As Figure 4 shown, specifically, the hot pressing part 803 includes a base 80301. On the base 80301, there are support columns 80302. On the support columns 80302, there is a second hydraulic rod 80303. The bottom output end of the second hydraulic rod 80303 is connected to a hot pressing plate 80304. On the lower surface of the hot pressing plate 80304, there is a heating wire 80305 in a shape of a double square frame. The inner circle size of the heating wire 80305 in the shape of a double square frame is larger than the outer circle size of the negative pressure groove 806. The hot pressing part 803 is mainly composed of a base 80301, support columns 80302, a second hydraulic rod 80303, and a hot pressing plate 80304. The support columns 80302 provide precise vertical movement through a hydraulic system, thereby controlling the movement of the hot pressing plate 80304. The heating wire 80305 in the shape of a double square frame arranged on the lower surface of the hot pressing plate 80304 is used to provide sufficient heat so that the upper plastic patch 804 can be fully softened during the hot pressing process. The design of the heating wire 80305 in the shape of a double square frame makes the heat energy evenly distributed, ensuring that the hot pressing plate 80304 can provide a consistent temperature throughout the heating process. The inner circle size is larger than the outer circle size of the negative pressure groove 806, which means that the hot pressing plate 80304 will cover the entire inner area of the negative pressure groove 806 during the hot pressing process, ensuring that the upper and lower plastic patches 805 can be fully heated during the bonding process.

[0041] As Figure 4As shown, when the second hydraulic rod 80303 pushes the hot pressing plate 80304 to move downward, the heated hot pressing plate 80304 contacts the lower plastic patch 805, applies pressure and transfers heat to the material; at this time, the upper plastic patch 804 is forced to press down and melt, gradually fitting together to form a seal; through the combination of hot pressing and negative pressure, the upper plastic patch 804 and the lower plastic patch 805 are tightly bonded to form a complete packaging structure; the design of the U-shaped heating wire 80305 makes the heat distribution more uniform, which can effectively avoid local overheating or overcooling, thereby improving the stability of the entire hot pressing process and product quality; precise control of the hot pressing process can speed up the packaging process, especially in automated production lines, which can significantly improve production efficiency and meet the needs of large-scale production.

[0042] like Figure 4 As shown, a pressure plate 80306 is provided on the lower surface of the hot pressing plate 80304, and the pressure plate 80306 is located on the inner side of the U-shaped heating wire 80305. The outer circle size of the pressure plate 80306 is smaller than the inner circle size of the packaging groove 807. When the hot pressing plate 80304 moves downward, the pressure plate 80306 will squeeze the bandage in the packaging groove 807. The concentrated pressure applied by the pressure plate 80306 makes it easier for the bandage to be accurately folded and compressed during the hot pressing process.

[0043] like Figure 3 As shown, the lower bracket 802 is a concave structure, and two lower brackets 802 are provided, and the two lower brackets 802 are fixedly connected by a connecting rod 808. The two lower brackets 802 are provided to ensure the stability of the lower plastic patch 805 during the hot pressing process.

[0044] like Figure 3 As shown, guide wheels 809 are provided inside the lower bracket 802, and three guide wheels 809 are provided. The guide wheels 809 are used to continuously guide the lower plastic patch 805 to ensure the continuity of the bandage packaging.

[0045] like Figure 3 As shown, a third hydraulic rod 8010 is provided on the upper surface of the fixing seat 1, and the output end of the third hydraulic rod 8010 is fixedly connected to the connecting rod 808. Through the third hydraulic rod 8010, the lower bracket 802 on the connecting rod 808 is longitudinally displaced, and after the hot pressing is completed, the packaging groove 807 on the lower plastic patch 805 is separated from the negative pressure groove 806.

[0046] like Figure 2As shown, a negative pressure pump 11 is fixedly installed on the upper surface of the fixing seat 1, and the negative pressure pump 11 is provided with two output ends. The two output ends of the negative pressure pump 11 are respectively connected to a first connector 12 and a second connector 13, the first connector 12 is located inside the negative pressure port 702, and the second connector 13 is located inside the negative pressure groove 806; and are used to generate negative pressure inside the negative pressure port 702 and the negative pressure groove 806.

[0047] Working principle: The rolled bandage is first installed on the unwinding wheel 3. After the unwinding wheel 3 is used, the bandage goes through various steps of unwinding, deviation correction, ironing, cutting, packaging and blister processing in sequence.

[0048] Specifically, after the bandage is cut, the blade causes it to break away from its original position and fall in the air. At this time, the design of the negative pressure port 702 generates an attractive force at the position of the crossbar 701, which quickly attracts and guides the falling bandage to the position of the crossbar 701. At the same time, by setting a guide channel, the movement direction of the bandage is restricted, thereby ensuring that it smoothly enters the plastic patch packaging slot 807 below.

[0049] Next, the heat pressing assembly is activated to move the upper plastic patch 804 downward, forcing it to contact and melt with the lower plastic patch 805, gradually forming a tightly fitting sealing structure. Through the synergistic effect of heat pressing and negative pressure, the upper and lower plastic patches 805 are firmly bonded, thereby forming a complete packaging structure outside the bandage.

[0050] Finally, the third hydraulic rod 8010 is activated to separate the componentized packaging structure from the negative pressure tank 806, and the continuity and stability of the bandage packaging are ensured by the guidance of the guide wheel 809.

[0051] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
