Description

Technical Field

[0001] This invention belongs to the field of bubble bag manufacturing technology, and specifically relates to a bubble bag manufacturing system. Background Technology

[0002] Bubble wrap is a widely used transparent flexible packaging material, extensively used for shock-absorbing and protective packaging of electronics, instruments, ceramics, handicrafts, home appliances, bicycles, kitchenware, furniture, hardware tools, glassware, and precision instruments. Its principle is to use a thin film to contain air, forming bubbles to prevent product impact and ensure protection when the product is subjected to vibration. It also provides thermal insulation, making it suitable for packaging or handling various products across different industries. Because the middle layer of the bubble wrap is filled with air, it is lightweight, elastic, sound-insulating, shock-absorbing, and abrasion-resistant.

[0003] However, existing bubble bag manufacturing equipment only focuses on production, and lacks various quality inspections during the production process. As a result, it is impossible to adjust the production module in a timely manner, resulting in a large number of unqualified bubble bags, which affects the quality of bubble bags and causes waste.

[0004] Therefore, further improvements will be made to address the aforementioned issues. Summary of the Invention

[0005] The main objective of this invention is to provide a bubble bag manufacturing system that links a blown film module, a heat-sealing and cutting module, a bubble size detection module, an independent bubble detection module, and a bubble film thickness detection module to perform quality inspection on the bubble bags during the production process to determine whether they meet the standards. Furthermore, the system can perform timely self-inspection and adjustment of the blown film module and the heat-sealing and cutting module to ensure the production of qualified bubble bags. It features advantages such as intelligence, structural stability, and high efficiency.

[0006] To achieve the above objectives, the present invention provides a bubble bag manufacturing system, comprising a blown film module, a heat-sealing and cutting module, a bubble size detection module, an independent bubble detection module, and a bubble film thickness detection module, wherein:

[0007] The blown film module heats the raw materials and forms a bubble film through a mold;

[0008] The heat-sealing and cutting module performs a first heat-sealing and cutting of the bubble wrap to form a plurality of bubble bag units; and the heat-sealing and cutting module performs a second heat-sealing and cutting of the bubble bag units to form bubble bags of a preset shape and size.

[0009] The bubble size detection module detects the number and size of bubbles in the bubble bag (uneven quantity and size can lead to unbalanced stress on the packaging, making it prone to damage during transportation). The bubble size detection module includes a first processor, a first image acquisition unit, and a first alarm unit. The first image acquisition unit acquires images of all bubbles in the bubble bag and transmits the acquired first image data to the first processor. The first processor first determines whether the number of bubbles is evenly distributed based on the first image data. If the distribution is even, the first processor issues a first qualified signal; otherwise, the first processor issues a quantity alarm signal, and the first alarm unit issues a first alarm upon receiving the quantity alarm signal. After the quantity detection, the first processor again determines whether the size of each bubble is within a preset range based on the first image data. If it is, the first processor issues a second qualified signal; otherwise, the first processor issues a size alarm signal, and the first alarm unit issues a second alarm upon receiving the size alarm signal.

[0010] The bubble independent detection module independently detects bubbles in the bubble bag (production errors can cause adjacent bubbles to merge together, meaning each bubble is not completely independent, thus affecting the cushioning performance of the bubble bag). The bubble independent detection module includes a second processor, a second image acquisition unit, and a second alarm unit. The second image acquisition unit acquires images of all bubbles in the bubble bag and transmits the acquired second image data to the second processor. The second processor determines whether each bubble is completely independent based on the second image data. If it is, the second processor issues a third qualified signal; otherwise, the second processor issues an independent alarm signal, and the second alarm unit issues a third alarm upon receiving the independent alarm signal.

[0011] The bubble film thickness detection module detects the thickness of the bubbles in the bubble bag (both excessively thick and thin bubbles can affect the bubble bag's pressure resistance and cushioning). The bubble film thickness detection module includes a third processor, a thickness detection sensor, and a third alarm unit. The thickness detection sensor collects the film thickness of all bubbles in the bubble bag and transmits the collected thickness data to the third processor. The third processor uses the thickness data to determine whether the thickness of each bubble is within a preset range. If it is, the third processor issues a fourth qualified signal; otherwise, the third processor issues a thickness alarm signal, and the third alarm unit issues a fourth alarm after receiving an independent alarm signal.

[0012] As a further preferred technical solution to the above technical solution, the feedback implementation of the bubble size detection module is as follows:

[0013] After receiving a quantity alarm signal or a size alarm signal, the heat-sealing and cutting module performs a first self-check on its own heat-sealing and cutting structure to determine whether the heat-sealing and cutting structure is working normally in terms of the number or size of bubbles. If it is normal, it will check again after a preset period to see if it receives a quantity alarm signal or a size alarm signal. Otherwise, it will directly generate a first self-check fault signal to the background management module (to remotely alarm and notify staff to carry out maintenance).

[0014] As a further preferred technical solution to the above technical solution, the feedback of the bubble independent detection module is specifically implemented as follows:

[0015] After receiving an independent alarm signal, the heat-sealing and cutting module performs a second self-check on its own heat-sealing and cutting structure to determine whether the heat-sealing and cutting structure is working properly in the independent operation of the bubble. If it is normal, it will check again after a preset period to see if an independent alarm signal has been received. Otherwise, it will directly generate a second self-check fault signal to the background management module (to remotely alarm and notify staff to carry out maintenance).

[0016] As a further preferred embodiment of the above technical solution, the feedback of the bubble film thickness detection module is specifically implemented as follows:

[0017] After receiving the thickness alarm signal, the blown film module performs a third self-check on its own blown film structure to determine whether the blown film structure is working properly in the bubble blowing process. If it is working properly, it checks again after a preset period to see if it receives the thickness alarm signal. Otherwise, it directly generates a third self-check fault signal to the background management module (to remotely alarm and notify staff to carry out maintenance).

[0018] As a further preferred embodiment of the above technical solution, the bubble bag manufacturing system also includes a hot-press strength detection module, wherein:

[0019] The heat seal strength detection module detects the heat seal strength of the bubbles in the bubble bag to determine whether the strength of the heat seal of each bubble meets the threshold. If it does, a fifth qualified signal is generated; otherwise, a strength alarm signal is generated and sent to the heat sealing and cutting module.

[0020] After receiving a secure alarm signal, the heat-sealing cutting module performs a fourth self-check on its heat-sealing cutting structure to determine whether the heat-sealing cutting structure is working properly in the bubble heat-sealing process (e.g., heat-sealing temperature and heat-sealing head pressure). If it is normal, it checks again after a preset period to see if a secure alarm signal has been received. Otherwise, it directly generates a fourth self-check fault signal to the background management module (to remotely alarm and notify staff to perform maintenance). Attached Figure Description

[0025] This invention discloses a bubble bag manufacturing system, comprising a blown film module, a heat-sealing and cutting module, a bubble size detection module, an independent bubble detection module, and a bubble film thickness detection module, wherein:

[0026] The blown film module heats the raw materials and forms a bubble film through a mold;

[0027] The heat-sealing and cutting module performs a first heat-sealing and cutting of the bubble wrap to form a plurality of bubble bag units; and the heat-sealing and cutting module performs a second heat-sealing and cutting of the bubble bag units to form bubble bags of a preset shape and size.

[0028] The bubble size detection module detects the number and size of bubbles in the bubble bag (uneven quantity and size can lead to unbalanced stress on the packaging, making it prone to damage during transportation). The bubble size detection module includes a first processor, a first image acquisition unit, and a first alarm unit. The first image acquisition unit acquires images of all bubbles in the bubble bag and transmits the acquired first image data to the first processor. The first processor first determines whether the number of bubbles is evenly distributed based on the first image data. If the distribution is even, the first processor issues a first qualified signal; otherwise, the first processor issues a quantity alarm signal, and the first alarm unit issues a first alarm upon receiving the quantity alarm signal. After the quantity detection, the first processor again determines whether the size of each bubble is within a preset range based on the first image data. If it is, the first processor issues a second qualified signal; otherwise, the first processor issues a size alarm signal, and the first alarm unit issues a second alarm upon receiving the size alarm signal.

[0029] The bubble independent detection module independently detects bubbles in the bubble bag (production errors can cause adjacent bubbles to merge together, meaning each bubble is not completely independent, thus affecting the cushioning performance of the bubble bag). The bubble independent detection module includes a second processor, a second image acquisition unit, and a second alarm unit. The second image acquisition unit acquires images of all bubbles in the bubble bag and transmits the acquired second image data to the second processor. The second processor determines whether each bubble is completely independent based on the second image data. If it is, the second processor issues a third qualified signal; otherwise, the second processor issues an independent alarm signal, and the second alarm unit issues a third alarm upon receiving the independent alarm signal.

[0030] The bubble film thickness detection module detects the thickness of the bubbles in the bubble bag (both excessively thick and thin bubbles can affect the bubble bag's pressure resistance and cushioning). The bubble film thickness detection module includes a third processor, a thickness detection sensor, and a third alarm unit. The thickness detection sensor collects the film thickness of all bubbles in the bubble bag and transmits the collected thickness data to the third processor. The third processor uses the thickness data to determine whether the thickness of each bubble is within a preset range. If it is, the third processor issues a fourth qualified signal; otherwise, the third processor issues a thickness alarm signal, and the third alarm unit issues a fourth alarm after receiving an independent alarm signal.

[0031] Specifically, the feedback from the bubble size detection module is implemented as follows:

[0032] After receiving a quantity alarm signal or a size alarm signal, the heat-sealing and cutting module performs a first self-check on its own heat-sealing and cutting structure to determine whether the heat-sealing and cutting structure is working normally in terms of the number or size of bubbles. If it is normal, it will check again after a preset period to see if it receives a quantity alarm signal or a size alarm signal. Otherwise, it will directly generate a first self-check fault signal to the background management module (to remotely alarm and notify staff to carry out maintenance).

[0033] More specifically, the feedback implementation for the independent bubble detection module is as follows:

[0034] After receiving an independent alarm signal, the heat-sealing and cutting module performs a second self-check on its own heat-sealing and cutting structure to determine whether the heat-sealing and cutting structure is working properly in the independent operation of the bubble. If it is normal, it will check again after a preset period to see if an independent alarm signal has been received. Otherwise, it will directly generate a second self-check fault signal to the background management module (to remotely alarm and notify staff to carry out maintenance).

[0035] Furthermore, the feedback from the bubble film thickness detection module is specifically implemented as follows:

[0036] After receiving the thickness alarm signal, the blown film module performs a third self-check on its own blown film structure to determine whether the blown film structure is working properly in the bubble blowing process. If it is working properly, it checks again after a preset period to see if it receives the thickness alarm signal. Otherwise, it directly generates a third self-check fault signal to the background management module (to remotely alarm and notify staff to carry out maintenance).

[0037] Furthermore, the bubble wrap manufacturing system also includes a hot-press strength testing module, in which:

[0038] The heat seal strength detection module detects the heat seal strength of the bubbles in the bubble bag to determine whether the strength of the heat seal of each bubble meets the threshold. If it does, a fifth qualified signal is generated; otherwise, a strength alarm signal is generated and sent to the heat sealing and cutting module.

[0039] After receiving a secure alarm signal, the heat-sealing cutting module performs a fourth self-check on its heat-sealing cutting structure to determine whether the heat-sealing cutting structure is working properly in the bubble heat-sealing process (e.g., heat-sealing temperature and heat-sealing head pressure). If it is normal, it checks again after a preset period to see if a secure alarm signal has been received. Otherwise, it directly generates a fourth self-check fault signal to the background management module (to remotely alarm and notify staff to perform maintenance).
