Description

Technical Field

[0001] This invention belongs to the field of automated processing equipment technology, and relates to an automated bottom sealing machine for honeycomb paper sleeves. Background Technology

[0002] With the continuous advancement of global industrialization, environmental pollution has become increasingly severe, and the research and application of environmentally friendly materials has become a core issue that urgently needs to be addressed. Honeycomb paper, a novel sandwich-type environmentally friendly material based on the natural honeycomb structure, uses adhesives to connect corrugated base paper into numerous hollow, three-dimensional regular hexagons. Due to its excellent cushioning and protective properties and biodegradability, it has been widely used in the packaging of fragile items (such as wine bottles).

[0003] In the processing of honeycomb paper sleeves, end sealing is one of the key steps. Unsealed paper sleeves have open ends, providing insufficient coverage for the contents, and their structural strength and protective performance are significantly inadequate, making it difficult to effectively protect the items inside. However, sealing one end of the paper sleeve significantly improves its overall structural stability and performance: the sealed sleeve forms a semi-enclosed protective cavity, which not only provides a tighter wrapping of the contents, effectively restricting displacement and movement within the cavity, but also enhances the fit and effectiveness of the protection.

[0004] However, traditional processing methods often rely on manual step-by-step operations or simple equipment to assist manual completion of the bottom sealing work, resulting in extremely low overall efficiency. Whether it is a segmented process of manual feeding, gluing, and bottom sealing, or a method of using simple equipment that requires manual material transfer, neither can achieve integrated processing of each step, making it difficult to meet the demands of large-scale, high-efficiency production.

[0025] This invention provides reference to [the relevant document]. Figures 1-6 In this embodiment of the invention, an automated bottom sealing machine for honeycomb paper sleeves includes: a mechanism frame 6 and a chain-structured circulating conveying mechanism 7 disposed on the mechanism frame 6; the circulating conveying mechanism 7 is provided with a plurality of multiple arrays of material support frames 71 arranged along its conveying direction, during processing, the paper sleeve is fed through the material support frames 71, and the end of the paper sleeve extends beyond the material support frames 71 for subsequent bottom sealing processing; A paper sleeve feeding mechanism 1 is provided at the feeding end of the circulating conveying mechanism 7. The paper sleeves are fed one by one into the material support frame 71 of the circulating conveying mechanism 7 through the paper sleeve feeding mechanism 1. A paper sleeve gluing mechanism 2 is provided on the side of both sides of the paper sleeve feeding mechanism 1. The paper sleeves are glued at the end of the paper sleeves before the paper sleeves are fed into the circulating conveying mechanism 7 by the paper sleeve feeding mechanism 1. The sides of the circulating conveying mechanism 7 are equipped with paper-top sealing mechanisms 4; during processing, the paper sleeve end is sealed by paper-top sealing mechanisms 4.

[0026] Furthermore, a heating mechanism 3 is provided between the paper sleeve gluing mechanism 2 and the paper top sealing mechanism 4, and between the paper top sealing mechanism 4 and the bottom sealing pressing mechanism 5. The heating mechanism 3 faces the end of the paper sleeve to be sealed. During processing, the glue is heated and activated by the heating mechanism 3, providing a processing basis for subsequent patch sealing and pressing.

[0027] Furthermore, the paper sleeve feeding mechanism 1 includes: a feeding conveyor belt 13 and a paper sleeve blocking unit 11 disposed at the discharge position of the feeding conveyor belt 13; During processing, the paper sleeve is fed through the feeding conveyor belt 13, which is located at the upper end of the feeding end of the circulating conveyor mechanism 7 to ensure that the paper sleeve can fall smoothly into the material support frame 71. The paper sleeve gluing mechanism 2 is located on the side of the discharge position of the feeding conveyor belt 13. During processing, the paper sleeve blocking unit 11 limits the falling of the paper sleeve. After the gluing work is completed, the limiting is released so that the paper sleeve is sent into the circulating conveyor mechanism 7 to continue the subsequent patch sealing and pressing processing. The paper sleeve blocking unit 11 includes a blocking plate 123 and a blocking lifting module 121 for driving the blocking plate 123 to move up and down. During processing, the blocking lifting module 121 drives the blocking plate 123 to descend to the discharge position of the feeding conveyor belt 13, thereby achieving the blocking effect. After the glue is applied, the blocking plate 123 is driven to retract, so that the paper sleeve can smoothly enter the circulating conveyor mechanism 7.

[0028] In order to ensure that the paper sleeve can stably enter the material holder 71 when it is dropped from the feeding conveyor belt 13, the paper sleeve blocking unit 11 is also provided with a guide plate 122. The guide plate 122 and the feeding conveyor belt 13 cooperate to form a guide gap, thereby realizing the limiting work of the paper sleeve discharge direction and improving the stability of the dropping.

[0029] Furthermore, in order to make the gluing process of the paper sleeve gluing mechanism 2 more uniform, the paper sleeve feeding mechanism 1 also includes: a set of gluing and material transfer mechanism 11 set at the upper end of the feeding conveyor belt 13. The gluing and transfer mechanism 11 includes: a transfer lifting module 111 and a transfer frame 114 mounted on the transfer lifting module 111; the transfer frame 114 is provided with a rotating shaft 115 and a drive motor 113 for driving the rotating shaft 115 to rotate; during processing, the transfer lifting module 111 drives the rotating shaft 115 to descend, so that the rotating shaft 115 contacts the paper sleeve in the gluing position, and the rotation of the rotating shaft 115 drives the paper sleeve to rotate synchronously, so that the paper sleeve gluing mechanism 2 can achieve uniform gluing along the circumference of the paper sleeve end, ensuring complete coating of the glue layer, uniform bonding area, and improving the bonding firmness of subsequent patch sealing.

[0030] The rotating shaft 115 is located at the lower end of the transfer frame 114 to facilitate contact with the paper sleeve. The drive motor 113 is located at the upper end of the transfer frame 114. The transfer frame 114 also has a drive shaft 112 that drives the output shaft of the drive motor 113. Power is transmitted between the drive shaft 112 and the rotating shaft 115 via belt drive. To ensure that the rotating shaft 115 can make smooth contact with the paper sleeve, multiple sets of thin conveyor belts are used for transmission between the drive shaft 112 and the rotating shaft 115. At the same time, the rotating shaft 115 has a transmission groove 116 for the conveyor belt to be embedded, which ensures reliable transmission between the drive shaft 112 and the rotating shaft 115 while avoiding direct contact between the conveyor belt and the paper sleeve, thus preventing wear on the paper sleeve.

[0031] Preferably, the feeding conveyor belt 13 is provided with at least two sets of parallel alternating baffle units 14. Each alternating baffle unit 14 includes an alternating baffle plate 141 and a baffle cylinder 142 for driving the alternating baffle plate 141 to lift and lower. During the feeding process of the feeding conveyor belt 13, each set of alternating baffle units 14 will perform alternating baffle work to ensure that only one set of paper sleeves is processed in each processing position of the gluing and transferring mechanism 11, so as to improve the stability of processing.

[0032] Furthermore, the paper feeding and sealing mechanism 4 includes a paper feeding unit 44 and a sealing unit 41. During processing, the paper feeding unit 44 feeds out the patch, and the sealing unit 41 picks up the material and performs the patch bonding work. The paper feeding unit 44 includes a feeding roller 441, a receiving roller 442, and a paper punching mechanism 443 disposed between the feeding roller 441 and the receiving roller 442. During processing, the feeding roller 441 outputs the material strip, which passes through the paper punching mechanism 443. The paper punching mechanism 443 then punches the patches on the material strip into shape and sends them out to the discharge position. Meanwhile, the receiving roller 442 simultaneously collects waste material, thus realizing continuous feeding and delivery of the patches. The bottom sealing unit 41 includes: a patch moving module 414 extending in the direction of the circulating conveying mechanism 7, a patch lifting module 411 mounted on the patch moving module 414, and a patch flipping module 412 mounted on the patch lifting module 411. The patch flipping module 412 is equipped with a pick-up nozzle 415 for picking up and bonding materials. During processing, the patch moving module 414 and the patch lifting module 411 work together to drive the pick-up nozzle 415 to pick up the patch in the paper feeding unit 44. Then, the patch flipping module 412 drives the pick-up nozzle 415 to flip, so that the patch and the end of the paper sleeve are accurately aligned and bonded, completing the bottom sealing bonding process. Furthermore, in order to improve the processing stability during the bottom sealing process, the upper end of the bottom sealing position of the circulating conveying mechanism 7 is provided with a clamping pneumatic claw 42 for clamping the end of the paper sleeve.

[0033] Furthermore, to improve the stability of the bottom sealing process, a patch gluing mechanism 43 is also provided at the lower end of the bottom sealing processing position of the circulating conveying mechanism 7. The glue nozzle of the patch gluing mechanism 43 faces the bottom sealing unit 41. Before the bottom sealing unit 41 performs the bottom sealing process, the bottom sealing unit 41 will pre-drive the patch into the processing position of the patch gluing mechanism 43 for patch gluing. In order to make the patch gluing process more uniform, the patch flipping module 412 is provided with a rotary motor 413 for driving the material suction nozzle 415 to rotate. When the patch is gluing, the rotary motor 413 drives the patch to rotate, so that the patch gluing mechanism 43 can achieve uniform gluing along the circumference of the patch, ensuring complete glue coating and uniform bonding area, and improving the bonding firmness of subsequent patch bottom sealing.

[0034] Furthermore, the paper-punching mechanism 443 includes: a paper-punching punch 448, a punch outer mold 445, a paper-punching die 446, and a paper-punching cylinder 444; wherein, the paper-punching cylinder 444 is connected to the paper-punching punch 448 for transmission; the punch outer mold 445 is sleeved on the paper-punching punch 448 and is used to guide the processing stroke of the paper-punching punch 448; and the paper-punching die 446 is located at the upper end of the paper-punching punch 448, and the paper-punching die 446 is formed with... The material feeding channel 449 is used for feeding the material strip, and the upper end face of the paper punching die 446 is formed with a material taking port 447 that is perpendicular to the material feeding channel 449. During processing, the material strip is conveyed to the position along the material feeding channel 449, and the paper punching cylinder 444 drives the paper punching punch 448 to work upward, punching the material in the corresponding area of ​​the material strip into a patch. The patch after being punched is exposed through the material taking port 447 for subsequent material taking suction nozzle 415 to take the material.

[0035] Furthermore, a bottom sealing pressing mechanism 5 is also provided at the rear processing position of the paper bottom sealing mechanism 4. During processing, the bottom sealing pressing mechanism 5 presses and shapes the end of the paper sleeve that has been sealed with the patch, so that the patch and the end of the paper sleeve can be reliably attached, ensuring that the bottom sealing structure is stable and firm. The bottom sealing and pressing mechanism 5 includes two sets of clamping units 51 and pressing units 52. The two sets of clamping units 51 are located at the upper and lower ends of the pressing processing position in the circulating conveying mechanism 7, respectively. Each set includes a clamping lifting module 511 that moves in the center direction and a clamping seat 512 installed on the clamping lifting module 511. During processing, the two sets of clamping lifting modules 511 drive the corresponding clamping seats 512 to move towards each other, positioning and clamping the paper sleeve.

[0036] The pressing unit 52 includes: a pressing moving module 521 that moves toward the circulating conveying mechanism 7, a pressing slide 522 mounted on the pressing moving module 521, and a pressing plate 523 elastically mounted on the pressing slide 522. During processing, the pressing moving module 521 drives the pressing plate 523 to move to the patching position, and the pressing plate 523 presses the patch tightly and adheres it to the end of the paper sleeve. The elastic mounting structure enables flexible pressing, avoids excessive pressing force that could damage the paper sleeve, and ensures uniform pressing and firm adhesion, thereby improving the sealing quality and finished product yield.
