Description

Technical Field

[0001] This invention relates to the field of conveying and packaging technology, and in particular to a conveying and packaging equipment for the production of breathable zinc oxide tape. Background Technology

[0002] Breathable zinc oxide tape is a medical tape made of cotton cloth coated with zinc oxide adhesive. It features good breathability, moderate adhesion, and low skin irritation, and is widely used in medical institutions for dressing fixation, catheter fixation, and surgical bandaging. During the production process, to facilitate subsequent transportation, storage, and use, the finished tape needs to be wound to a predetermined length around a paper or plastic core, forming a uniform roll. For transportation safety and moisture and dust protection, the wound tape rolls also require external packaging, typically using heat-shrink film or plastic bags.

[0003] However, current post-processing equipment for breathable zinc oxide tape has the following shortcomings: First, the processes are fragmented and the functional integration is low. Existing tape winding and packaging machines are independent devices. After the tape is wound, it needs to be manually transferred to the packaging station for sealing. The winding and packaging processes cannot be completed continuously on the same equipment. This fragmented equipment layout results in a large production line footprint and numerous process connections, severely impacting overall production efficiency. Second, automation is insufficient. Because winding and packaging require switching between different devices, operators need to repeatedly pick up and put down the tape rolls, increasing manual labor intensity and easily causing damage, dirt, or loosening and deformation of the tape rolls during transfer, affecting the quality and consistency of the finished product. Third, equipment adaptability is poor. Different specifications of breathable zinc oxide tape (such as different widths and lengths) require matching different core sizes and packaging methods. Existing independent equipment requires downtime for tooling changes when switching specifications, resulting in long adjustment cycles and making it difficult to meet the needs of flexible production with multiple specifications.

[0004] Therefore, how to develop an integrated equipment that combines tape winding, core assembly, and outer packaging functions and can adapt to multi-specification production is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The technical problem this invention aims to solve is that existing post-processing equipment for breathable zinc oxide tape has fragmented functions, requiring the winding and packaging processes to be completed independently on different equipment, resulting in low efficiency and low functional integration; there are many manual transfer steps, which can easily cause damage to the tape rolls; and the adjustment cycle for switching equipment specifications is long, making it difficult to meet the needs of flexible production with multiple specifications.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a material conveying and packaging equipment for producing breathable zinc oxide tape, including a side-mounted frame and a guide wheel group for inputting breathable zinc oxide tape. Several sets of first horizontal assembly frames and second horizontal assembly frames are installed on the outside of the side-mounted frame. Core cylinder feeding guide rails and adjustable inclined connecting guide rails are provided on the side-mounted frame between the first horizontal assembly frames and the second horizontal assembly frames. An electric control cutting component, an electric heating component and a packaging material conveying component are installed inside the first horizontal assembly frame. An electric control guide arm for controlling the translation of the core cylinder is movably installed inside the second horizontal assembly frame.

[0007] Furthermore, both the first and second horizontal assembly frames have several strip-shaped assembly openings. The electrically controlled cutting component and the electrically heated component are fixedly assembled with the first horizontal assembly frame by bolts passing through the strip-shaped assembly openings. Detachable electrically controlled translation devices are installed on the first horizontal assembly frame at the position corresponding to the packaging material conveying component and on the second horizontal assembly frame at the position corresponding to the electrically controlled guide arm.

[0008] Furthermore, the detachable electrically controlled translation device includes a horizontal guide rail fixed by screws, an electrically controlled lead screw mounted on the horizontal guide rail, and an internally threaded translation slider threaded onto the electrically controlled lead screw.

[0009] Furthermore, the electrically controlled cutting assembly includes a first fixed bracket bolted to the side wall of the first horizontal assembly frame, a horizontal cutting frame fixed to the top of the first fixed bracket, a fixed cutting blade fixed to the inner wall of one side of the horizontal cutting frame, and a sliding cutting blade slidably mounted on the inner wall of the other side of the horizontal cutting frame.

[0010] Furthermore, the electric heating assembly includes a second fixed bracket bolted to the side wall of the first horizontal assembly frame, an arc-shaped cover fixed to the end of the second fixed bracket, an electric heating element installed on the arc-shaped surface inside the arc-shaped cover, and an electrically controlled air pump fixed to the second fixed bracket.

[0011] Furthermore, the packaging material conveying assembly includes a lateral assembly frame mounted on an internally threaded translation slider, an electrically controlled assembly rotating shaft movably mounted inside the lateral assembly frame, an arc-shaped guide cover hinged to the lateral assembly frame, and an electrically controlled adjusting strut.

[0012] Furthermore, the electrically controlled guide arm includes a lateral mounting frame mounted on an internally threaded translation slider, an electrically controlled adjustment disc movably mounted inside the lateral mounting frame, and a magnetically controlled locking arm fixed at the lateral center position of the electrically controlled adjustment disc.

[0013] Furthermore, a detachable top guide cover is installed at the end of the arc-shaped guide cover, and an electric heating component is installed on the arc-shaped guide cover.

[0014] The beneficial effects of this invention are: (1) By setting up a first horizontal assembly frame and a second horizontal assembly frame, the present invention integrates the electric control cutting component, the electric heating component, the packaging material conveying component and the electric control guide arm on the same lateral mounting frame, realizing the integrated operation of tape conveying, core feeding, cutting, heating and packaging, thereby improving the functional integration and production efficiency.

[0015] (2) The present invention enables the packaging material conveying component and the electric control guide arm to be moved and adjusted along the horizontal guide rail by a detachable electric control translation device. Combined with the adjustable inclined connecting guide rail, it can flexibly adapt to different specifications of tape rolls and core sizes, reducing the adjustment time when switching specifications.

[0016] (3) The present invention realizes automatic clamping and guiding conveying of the core tube through the structural design of the electronically controlled adjustment plate and the magnetically controlled locking arm. Combined with the guiding structure of the arc-shaped guide cover and the top guide cover, the packaging material can be accurately wrapped on the outside of the tape roll, improving the packaging quality and consistency.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0025] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] like Figure 1-5As shown, a material conveying and packaging device for producing breathable zinc oxide tape according to the present invention includes a lateral mounting frame 100, on the outside of which are several sets of first horizontal assembly frames 110 and second horizontal assembly frames 120. The first horizontal assembly frames 110 and second horizontal assembly frames 120 are arranged in pairs, with an installation gap between them. A core cylinder feeding guide rail 200 and an adjustable inclined connecting guide rail 210 are provided on the lateral mounting frame 100 between the first horizontal assembly frames 110 and the second horizontal assembly frames 120. The core cylinder feeding guide rail 200 is used to convey the core cylinder to be assembled to the working position, and the adjustable inclined connecting guide rail 210 is used to guide the wound tape roll along an inclined direction. An electronically controlled lever 710 is installed at its connecting end for switching the core cylinder in different positions. An electrically controlled cutting assembly 300, an electrically heated assembly 400, and a packaging material conveying assembly 500 are installed inside the first horizontal assembly frame 110. An electrically controlled guide arm 600 for controlling the translation of the core cylinder is movably installed inside the second horizontal assembly frame 120. A guide wheel assembly 640 is installed at the feed end of the lateral mounting frame 100 to smoothly feed the breathable zinc oxide tape into the equipment.

[0027] Both the first horizontal assembly frame 110 and the second horizontal assembly frame 120 have several strip-shaped assembly openings 130, which are elongated through holes used for installing and adjusting the positions of various functional components. The electrically controlled cutting component 300 and the electrically heated component 400 are fixedly assembled to the first horizontal assembly frame 110 by bolts passing through the strip-shaped assembly openings 130. By adjusting the fixing position of the bolts in the strip-shaped assembly openings 130, the positions of the cutting component and the heating component along the length of the assembly frame can be adjusted. Detachable electrically controlled translation devices 650 are installed on the first horizontal assembly frame 110 at the position corresponding to the packaging material conveying component 500 and on the second horizontal assembly frame 120 at the position corresponding to the electrically controlled guide arm 600, enabling the packaging material conveying component 500 and the electrically controlled guide arm 600 to translate along the assembly frame.

[0028] The detachable electrically controlled translation device 650 includes a horizontal guide rail 220 fixed to a first horizontal assembly frame 110 or a second horizontal assembly frame 120 by screws, an electrically controlled lead screw 230 mounted on the horizontal guide rail 220, and an internally threaded translation slider 240 threaded onto the electrically controlled lead screw 230. The electrically controlled lead screw 230 is driven to rotate by an external servo motor, which drives the internally threaded translation slider 240 to perform linear reciprocating motion along the horizontal guide rail 220, thereby controlling the translation of the functional components mounted on the internally threaded translation slider 240.

[0029] The electrically controlled cutting assembly 300 includes a first fixed bracket 310 bolted to the side wall of the first horizontal mounting frame 110, a horizontal cutting frame 320 fixed to the top of the first fixed bracket 310, a fixed cutting blade 330 fixed to the inner wall of one side of the horizontal cutting frame 320, and a sliding cutting blade 340 slidably mounted on the inner wall of the other side of the horizontal cutting frame 320. When the tape roll is conveyed to the cutting position, the sliding cutting blade 340 is horizontally displaced under the action of an external drive mechanism, moving towards the fixed cutting blade 330, and the two work together to cut the tape. By adjusting the stroke of the sliding cutting blade 340, tape rolls of different widths can be accommodated.

[0030] The electric heating assembly 400 includes a second fixing bracket 410 bolted to the side wall of the first horizontal assembly frame 110, an arc-shaped cover 420 fixed to the end of the second fixing bracket 410, an electric heating element 430 mounted on the inner arc-shaped surface of the arc-shaped cover 420, and an electrically controlled air pump 440 fixed to the second fixing bracket 410. The shape of the arc-shaped cover 420 matches the outer contour of the tape roll. The electric heating element 430 is used to heat and shrink the packaging material wrapped around the outside of the tape roll, making it tightly adhere to the surface of the tape roll. The electrically controlled air pump 440 blows hot air into the heating area, accelerating the shrinkage process of the packaging material and improving packaging efficiency.

[0031] The packaging material conveying assembly 500 includes a lateral assembly frame 510 mounted on an internally threaded translation slider 240, an electrically controlled assembly rotating shaft 520 movably mounted inside the lateral assembly frame 510, an arc-shaped guide cover 530 hinged to the lateral assembly frame 510, and an electrically controlled adjusting strut 540. Packaging material (such as heat-shrink film rolls) is mounted on the electrically controlled assembly rotating shaft 520 and is driven to rotate and release. The arc-shaped guide cover 530 unfolds or retracts under the control of the electrically controlled adjusting strut 540, guiding the packaging material to the outer surface of the tape roll. A top guide cover 550 is mounted at the end of the arc-shaped guide cover 530 to further guide the packaging material to spread along the axial direction of the tape roll. The top guide cover 550 can be manually replaced with the corresponding size to achieve a suitable fit for different tape specifications. The packaging material conveying assembly 500 has a built-in cutting blade for automatic cutting after the packaging film is wound. An electric heating component 400 is installed on the arc-shaped material guide cover 530, which allows the packaging material to be preheated simultaneously during the material guiding process, which helps with subsequent shrink wrapping.

[0032] The electrically controlled guide arm 600 includes a lateral mounting frame 610 mounted on an internally threaded translation slider 240, an electrically controlled adjusting plate 620 movably mounted inside the lateral mounting frame 610, and a magnetically controlled locking arm 630 fixed at the lateral center position of the electrically controlled adjusting plate 620. The electrically controlled adjusting plate 620 includes a circular adjusting plate 621 controlled by a centrally mounted motor 623, and a strip-shaped telescopic opening 622 is provided on the side wall of the circular adjusting plate 621. The magnetically controlled locking arm 630 includes a fixed locking arm 631 fixed to the side wall of the circular adjusting plate 621, a sliding adjusting block 632 slidably mounted inside the strip-shaped telescopic opening 622, a movable locking arm 633 fixed to the side wall of the sliding adjusting block 632, an electromagnet 634 mounted on the inner wall of the strip-shaped telescopic opening 622, and an iron spring 635 controlled by the electromagnet 634. A pressure sensor 636 is installed on the inner side of the fixed locking arm 631 to detect the clamping force in real time when clamping the core, ensuring reliable locking. When the electromagnet 634 is energized, the iron spring 635 is compressed and pulled by the magnetic force, causing the sliding adjusting block 632 to slide along the strip-shaped telescopic opening 622. The movable locking arm 633 moves closer to the fixed locking arm 631, clamping the inner wall of the core located between the two. When the electromagnet 634 is de-energized, the iron spring 635 returns to its original position, and the movable locking arm 633 releases the core. The circular adjusting disc 621 is driven to rotate by the central motor 623, which can adjust the angle and direction of clamping the core. Combined with the translational movement of the detachable electrically controlled translation device 650, precise delivery and positioning of the core cylinder can be achieved.

[0033] The complete workflow of the material conveying and packaging equipment of the present invention is as follows: First, the breathable zinc oxide tape is guided downward from the upper guide wheel assembly 640. At this time, the optical recognition probe 700 installed on the outer wall of the core cylinder feeding guide rail 200 detects in real time whether the tape has reached the designated position. When the optical recognition probe 700 recognizes the tape signal, the control system sends a control command to the electric control screw 230 on the second horizontal assembly frame 120, driving the internal thread translation slider 240 to move the electric control guide arm 600 towards the lower end of the core cylinder feeding guide rail 200 towards the discharge port. The core cylinder feeding guide rail 200 conveys the core to the discharge port position, and the magnetic locking arm 630 at the front end of the electric control guide arm 600 is inserted into the core at the discharge port. Subsequently, the electromagnet 634 is energized and activated. The iron spring 635 contracts under electromagnetic force, causing the sliding adjusting block 632 to slide downwards along the strip-shaped telescopic opening 622. This causes the movable locking arm 633 to descend, cooperating with the fixed locking arm 631 to clamp the inner wall of the cylinder. The pressure sensor 636 on the inner side of the fixed locking arm 631 detects the clamping force signal in real time and feeds it back to the control system. When the clamping force reaches the threshold set by the control system, the locking is confirmed to be complete, ensuring that the cylinder will not loosen or shift during subsequent high-speed conveying.

[0034] After locking is confirmed, the lead screw 230 rotates in the reverse direction under the command of the control system, driving the internal thread translation slider 240 to move the electrically controlled guide arm 600 and the clamped core forward, moving the core directly below the unloading position of the breathable zinc oxide tape. The guide wheel assembly 640, driven by the servo motor, begins to release the tape downwards. Simultaneously, the central motor 623 starts, driving the circular adjusting disc 621 to rotate, thereby causing the clamped core to rotate synchronously, completing the tape winding operation. The control system monitors the length of tape released by the guide wheel assembly 640 in real time through an encoder and automatically calculates the current winding diameter of the tape roll on the outside of the core based on the number of rotations of the circular adjusting disc 621. When the winding diameter reaches the preset specification value in the control system, the control system sends a stop command, the guide wheel assembly 640 stops releasing material, and the central motor 623 stops rotating. After the tape is wrapped, the sliding cutting blade 340 moves horizontally within the horizontal cutting frame 320 under the control of the drive mechanism, sliding towards the fixed cutting blade 330. The two work together to neatly cut the tape at the set position. The stroke of the sliding cutting blade 340 can be preset and adjusted in the control system according to the tape width.

[0035] After the tape is cut, the core with the tape roll continues to move forward with the electrically controlled guide arm 600. First, it passes through the area of ​​the electric heating component 400 installed on the first horizontal assembly frame 110. The electrically controlled air pump 440 starts blowing air, and the airflow is heated by the electric heating element 430 inside the arc-shaped cover 420 to form hot air at a controllable temperature. This preheats the surface of the tape roll, raising its temperature to a set value, preparing for the subsequent heating and lamination of the packaging film. After preheating, the tape roll continues to move forward with the electrically controlled guide arm 600 to the packaging material conveying component 500. The electrically controlled assembly rotating shaft 520 starts rotating under the command of the control system, evenly releasing the transparent packaging film from the roll. The electrically controlled adjusting strut 540 extends and retracts according to a preset program, controlling the arc-shaped guide cover 530 to unfold to a set angle, accurately guiding the transparent packaging film to the outer surface of the tape roll. The top guide cover 550 at the end of the arc-shaped guide cover 530 ensures the packaging film is evenly spread and covers the outer perimeter of the tape roll along its axial direction. The top guide cover 550 can be manually replaced with the appropriate size beforehand to achieve a proper fit for different tape specifications. After the packaging film has been wound around the tape roll 1 to 2 times, the cutting blade inside the packaging material conveying assembly 500 is controlled to neatly cut the packaging film. Subsequently, the tape roll, wrapped with packaging film but not yet fully sealed, moves backward again with the electrically controlled guide arm 600 back to the area of ​​the electrically heated assembly 400. The electrically controlled air pump 440 and the electrically heated plate 430 work together to blow high-temperature hot air onto the surface of the tape roll, using the hot air sealing principle to quickly and tightly seal the transparent heat-sealing film onto the surface of the tape roll, completing the packaging seal. After all packaging processes are completed, the control system sends a power-off command to the electromagnet 634. The iron spring 635 resets and drives the movable locking arm 633 to rise and loosen the inner wall of the core. At the same time, the electric control screw 230 performs a rapid forward and reverse switching under the command of the control system, causing the internal thread translation slider 240 to generate a rapid reciprocating linear motion. The inertial force generated by the acceleration smoothly throws the finished tape roll off the magnetic locking arm 630, completing the single operation of wrapping, packaging and detaching the finished tape.

[0036] The equipment is equipped with multiple sets of staggered first horizontal assembly frames 110 and second horizontal assembly frames 120. Each assembly frame is independently configured with an electrically controlled guide arm 600 and its corresponding electrically controlled cutting component 300, electrically heated component 400, and packaging material conveying component 500. This allows the equipment to simultaneously and in parallel perform conveying and packaging operations on multiple tape rolls, with each station coordinated by the control system to prevent interference. An electrically controlled lever 710 is installed at the connecting end of the adjustable inclined connecting guide rail 210 to guide the cores at different positions. When the monitoring module of the control system detects that the core quantity in the core loading guide rail 200 of a certain station is lower than a set threshold, the electrically controlled lever 710 is activated, guiding excess cores from the storage bin or other stations along the adjustable inclined connecting guide rail 210 to the shortage position. This achieves automatic balancing adjustment of cores between stations, preventing situations where one position has excessive core accumulation while another position has insufficient cores. A pressure sensor is installed at the bottom of the core feeding guide rail 200 to monitor the stacking weight and quantity of cores inside the guide rail in real time. The control system automatically judges the supply and demand of cores at each station based on the feedback signal from the pressure sensor and executes core replenishment and distribution instructions, making the equipment more automated, enabling it to operate continuously and stably for a long time, and significantly improving overall production efficiency.
