Description

Technical Field

[0001] This invention relates to the field of nonwoven finger sleeve technology, and in particular to a finger sleeve production equipment. Background Technology

[0002] Finger cots are lightweight, disposable, highly absorbent, or clean and protective finger coverings, primarily made of PP / spunlace nonwoven fabric. They are widely used in pet cleaning, oral care, laboratory dust prevention, and everyday household chores. Nonwoven finger cots emphasize absorbency, softness, and biocompatibility, making them suitable for skin contact applications. Currently, the production equipment for nonwoven finger cots has a relatively simple structure and fragmented functions, especially with the die-cutting and packaging processes being performed separately. These two processes are independent and not smoothly integrated, resulting in low automation and limited production efficiency in nonwoven finger cot production lines. Furthermore, traditionally, after die-cutting, nonwoven finger cots are typically discharged directly, separating the nonwoven finger cots from waste fabric. During packaging, manual labor or separate sorting equipment is required to neatly arrange and count the nonwoven finger cots, leading to high costs in terms of time and labor. Summary of the Invention

[0003] The purpose of this invention is to provide a finger sleeve production equipment to solve the problems of low automation and limited production efficiency of existing non-woven finger sleeve production equipment, and the fact that non-woven finger sleeves and waste fabrics are separated after die-cutting and need to be sorted separately, resulting in high costs in terms of time and labor.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A finger sleeve manufacturing device, comprising: A feeding rack is used to load nonwoven fabric rolls and unwind the nonwoven fabric rolls; The die-cutting mechanism is divided into a heat-sealing working section and a ring-cutting working section along the forward direction of the nonwoven fabric. The heat-sealing working section heats and indents the unwound nonwoven fabric, and the ring-cutting working section cuts the nonwoven fabric based on the indentation trajectory to form an incompletely cut finger sleeve. A traction mechanism for pulling the die-cut nonwoven fabric; A finger sleeve separation mechanism, which separates the nonwoven fabric from the finger sleeve during traction; The material counting and storage mechanism continuously receives, counts, and temporarily stores the falling finger sleeves, and then distinguishes the finger sleeves after they have been counted to a certain number.

[0005] A further technical solution is as follows: the die-cutting mechanism includes a die-cutting frame, a heat-sealing cutter roller, a transducer, an upper circumferential cutting cutter roller, and a lower circumferential cutting roller. The heat-sealing cutter roller, the upper circumferential cutting cutter roller, and the lower circumferential cutting roller are all rotatably mounted on the die-cutting frame and driven by an external power source. The transducer is disposed on the die-cutting frame and electrically connected to an external functional device. A channel for the nonwoven fabric to pass through is formed between the heat-sealing cutter roller and the transducer and between the upper circumferential cutting cutter roller and the lower circumferential cutting roller.

[0006] A further technical solution is that the transducer is an electric heater or a high-frequency induction heater.

[0007] A further technical solution is that the belts of both the upper belt conveyor structure and the lower belt conveyor structure are multiple evenly distributed thin strip belts.

[0008] A further technical solution is as follows: the finger sleeve separation mechanism includes a crank-connecting rod-slider mechanism, a crossbar, and a pressing hand. The crank-connecting rod-slider mechanism is mounted on the frame and driven by an external power source. The crossbar is horizontally mounted on the slider of the crank-connecting rod-slider mechanism. The pressing hand is mounted on the crossbar, and the working end of the pressing hand is adapted to the traction mechanism and the material counting temporary storage mechanism.

[0009] A further technical solution is as follows: the material storage mechanism includes a micro-motion cylinder, a base, and a receiving trough. The cylinder and the base are both mounted on the frame. The receiving trough is slidably mounted on the base via a slide rail assembly. The power output end of the cylinder is connected to the receiving trough, and the stroke direction of the cylinder is consistent with the sliding direction of the receiving trough. The feeding end of the receiving trough is adapted to the working end of the finger sleeve separation mechanism.

[0010] A further technical solution is that a brush is provided on the feeding end of the receiving trough.

[0011] A further technical solution is that a counting sensor is provided near the working end of the finger sleeve separation mechanism, and the signal transmission end of the counting sensor is electrically connected to the control end of the finger sleeve production equipment.

[0012] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: This invention proposes a finger sleeve production device. During die-cutting, the heat-sealing unit heats and indents the unwound nonwoven fabric. Then, the ring-cutting unit cuts the nonwoven fabric based on the indentation trajectory to form an incompletely cut finger sleeve. This step serves two purposes: first, it heat-seales the double-layer nonwoven fabric to form the finger sleeve; second, it incompletely cuts the finger sleeve, ensuring synchronous material transport of the finger sleeve and nonwoven fabric. This avoids the added steps of separating the finger sleeve after die-cutting, simplifies the process, and facilitates the integrated transport of the finger sleeve and nonwoven fabric (waste material), saving equipment costs and offering high efficiency and convenience. Furthermore, during traction, a finger sleeve separation mechanism separates the finger sleeve from the nonwoven fabric. This, combined with a material counting and temporary storage mechanism, counts and distinguishes misaligned finger sleeves during packaging, preventing material retrieval errors during packaging and enabling continuous production without stopping the machine.

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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example

[0029] This implementation example Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a finger sleeve manufacturing device includes: Feeding rack 1 is used to load non-woven fabric rolls and unwind the non-woven fabric rolls; Die-cutting mechanism 2 is divided into a heat-sealing working section and a ring-cutting working section along the forward direction of the nonwoven fabric. The heat-sealing working section heats and crimps the unwound nonwoven fabric, and the ring-cutting working section cuts the nonwoven fabric based on the crimping trajectory to form an incompletely cut finger sleeve. Traction mechanism 3, traction mechanism 3 pulls the die-cut nonwoven fabric; Finger sleeve separation mechanism 4 separates the non-woven fabric from the finger sleeve during traction; The material counting and storage mechanism 5 continuously receives, counts, and temporarily stores the falling finger sleeves, and then distinguishes the finger sleeves after counting them according to a certain number.

[0030] The feeding rack 1 holds rolls of non-woven fabric (usually in pairs), and unwinds the rolls. During die-cutting, the heat-sealing section of the die-cutting mechanism 2 first heats and indents the unwound non-woven fabric. The heating method can be electric heating or ultrasonic welding to press the double-layer non-woven fabric together. Then, the circumferential cutting section cuts the non-woven fabric based on the indentation trajectory to form an incompletely cut finger sleeve. This die-cutting step serves two purposes: first, to heat-seal the double-layer non-woven fabric to form a finger sleeve; and second, to incompletely cut the finger sleeve, ensuring that the finger sleeve moves with the non-woven fabric. The synchronous conveying effect avoids the need for finger separation after die-cutting, which increases the workload and simplifies the process. It also facilitates the integrated conveying of finger sleeves and non-woven fabric (waste), saving equipment costs and being highly efficient and convenient. The traction mechanism 3 pulls the die-cut non-woven fabric and the finger sleeves that have not been separated. During traction, the finger sleeve separation mechanism 4 separates the finger sleeves from the non-woven fabric (waste). The non-woven fabric waste is rolled up separately, and the finger sleeves fall downward into the inlet of the counting and storage mechanism 5. The counting and storage mechanism 5 counts and distinguishes the finger sleeves during packaging, avoiding errors in material handling during packaging, and enabling production without stopping the machine.

[0031] It is worth noting that the heat-sealing section heats and indents (bonds) the unwound nonwoven fabric, which can play a pre-shaping effect (indentation cooling hardening) when forming finger sleeves on the nonwoven fabric, and can ensure that the area around the finger sleeve does not get fuzzy when the ring-cutting section performs pressure cutting based on the indentation trajectory.

[0032] All of the above-mentioned departments (work units) have shared or independent power sources. Example

[0033] Based on the above embodiments, this implementation is as follows: Figure 6 As shown, the die-cutting mechanism 2 includes a die-cutting frame 21, a heat-sealing cutter roller 22, a transducer 23, an upper circumferential cutting cutter roller 24, and a lower circumferential cutting cutter roller 25. The heat-sealing cutter roller 22, the upper circumferential cutting cutter roller 24, and the lower circumferential cutting cutter roller 25 are all rotatably mounted on the die-cutting frame 21 and driven by an external power source. The transducer 23 is mounted on the die-cutting frame 21 and is electrically connected to external functional equipment. A channel for the nonwoven fabric to pass through is formed between the heat-sealing cutter roller 22 and the transducer 23 and between the upper circumferential cutting cutter roller 24 and the lower circumferential cutting cutter roller 25.

[0034] The nonwoven fabric is first heated by transducer 23, or the transducer 23 heats the heat-sealing roller 22 to form a finger-shaped indentation on the nonwoven fabric. Then, the indentation is completed by the cooperation of the upper ring-cutting roller 24 and the lower ring-cutting roller 25 to obtain a finger sleeve that is not completely separated from the nonwoven fabric. This step is to ensure that the finger sleeve can move forward synchronously with the nonwoven fabric, which is convenient for conveying and subsequent boxing and packaging.

[0035] It is worth noting that transducer 23 can also be an ultrasonic wave generating component.

[0036] Preferably, the transducer 23 is an electric heater or a high-frequency induction heater.

[0037] The die-cutting blade of the ring-cutting upper roller 24 can be set with intermittently distributed small notches, which can form a dotted line-like cut to ensure that the finger sleeve is not completely cut off and can move forward with the nonwoven fabric.

[0038] The shape of the annular cutter on the ring-cutting upper cutter roller 24 is the same as the shape of the annular pressing cutter on the heat-sealing cutter roller 22, or it can be slightly larger, so that some indentation can be retained after pressing and cutting to prevent the finger sleeve from getting fuzzy. Example

[0039] Based on the above embodiments, this implementation is as follows: Figure 3 , Figure 4 and Figure 5 As shown, the belts of the upper belt conveyor structure 31 and the lower belt conveyor structure 32 are both multiple evenly distributed thin strip belts.

[0040] Both the upper belt conveyor structure 31 and the lower belt conveyor structure 32 are traditional belt conveyor mechanisms. The lower belt of the upper belt conveyor structure 31 and the upper belt of the lower belt conveyor structure 32 clamp and convey the non-woven fabric.

[0041] At the tail ends of the upper belt conveyor structure 31 and the lower belt conveyor structure 32, the non-woven fabric waste after separating the eye patches can be discharged upwards for easy collection. It should be noted that this location can also provide traction for the forward movement of the non-woven fabric.

[0042] Preferably, both the upper belt conveyor structure 31 and the lower belt conveyor structure 32 consist of multiple evenly distributed thin strip belts. The thin strip belts are spaced apart to facilitate the separation of the nonwoven fabric and the finger sleeve by the finger sleeve separation mechanism 4.

[0043] Preferably, the finger sleeve separation mechanism 4 includes a crank-connecting rod-slider mechanism 41, a crossbar 42, and a pressing hand 43. The crank-connecting rod-slider mechanism 41 is mounted on the frame and driven by an external power source. The crossbar 42 is horizontally mounted on the slider of the crank-connecting rod-slider mechanism 41. The pressing hand 43 is mounted on the crossbar 42, and the working end of the pressing hand 43 is adapted to the traction mechanism 3 and the material counting temporary storage mechanism 5.

[0044] The crank-connecting rod-slider mechanism 41 is a conventional motor-driven motion mechanism. The slider can move vertically back and forth, thereby causing the crossbar 42 and the pressing hand 43 to move up and down back and forth. The pressing hand 43 is adapted to the row of finger sleeves and the material storage mechanism 5, separating the finger sleeves from the non-woven fabric and pressing them into the feed port of the material storage mechanism 5.

[0045] A sensor 7 (mainly used for counting) is installed near the connecting rod of the crank-connecting rod-slider mechanism 41. This sensor, in coordination with the built-in program of the PLC controller, primarily refers to the coordinated operation between the sleeve separation mechanism 4 and the material counting and storage mechanism 5. Example

[0046] Based on the above embodiments, this implementation is as follows: Figure 7 , Figure 8 and Figure 9 As shown, the material storage mechanism 5 includes a micro-motion cylinder 51, a base 52, and a receiving groove 53. Both the cylinder 51 and the base 52 are mounted on the frame. The receiving groove 53 is slidably mounted on the base 2 via a slide rail assembly. The power output end of the cylinder 51 is connected to the receiving groove 53, and the stroke direction of the cylinder 51 is consistent with the sliding direction of the receiving groove 53. The feeding end of the receiving groove 53 is adapted to the working end of the finger sleeve separation mechanism 4.

[0047] Working in conjunction with the counting sensor 7, once the counting sensor 7 detects the working frequency of the finger sleeve separation mechanism 4 to obtain the number of finger sleeves, the cylinder 51 extends or retracts, causing the receiving groove 53 to slide briefly on the base 52. At this time, the finger sleeves that re-enter the receiving groove 53 facilitate partial misalignment with the finger sleeves in front of them. This prevents incorrect material handling during packaging and ensures that the number of finger sleeves in each package is accurate. Moreover, the material counting and temporary storage mechanism 5 does not interfere with other working mechanisms when performing misalignment differentiation, eliminating the need for machine downtime and enabling highly efficient production.

[0048] Preferably, a brush 6 is provided on the feed end of the receiving trough 53.

[0049] The brush 6 prevents the finger sleeve from being lifted up when the pressure hand 43 of the finger sleeve separation mechanism 4 rises and resets, thus affecting the collection of the finger sleeve.

[0050] Preferably, a counting sensor 7 is provided near the working end of the finger sleeve separation mechanism 4, and the signal transmission end of the counting sensor is electrically connected to the control end of the finger sleeve production equipment.

[0051] 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.
