Description

Technical Field

[0001] The utility model relates to the technical field of food production, in particular to a bag - feeding bagging and sealing device. Background Art

[0002] As a new type of candy product, bursting - bead candy has been favored by consumers in recent years due to its unique shape, rich taste and interestingness. With the continuous expansion of market demand, the production process and packaging technology of bursting - bead candy are also constantly developing and progressing.

[0003] Traditional packaging forms of bursting - bead candy mainly use cans, bottles, etc., which have problems such as high cost and inconvenient carrying. Bag - feeding packaging, due to its advantages of low cost, good portability and easy storage, has gradually become a new trend in bursting - bead candy packaging.

[0004] When the existing bag - feeding bagging and sealing device is applied to the box - type sealing of bursting - bead candy, it is difficult to ensure that the sealing pressure of each packaging bag is uniform, and problems such as loose sealing and air leakage are likely to occur, affecting product quality and shelf life. Most of the existing devices lack a real - time detection function for sealing quality, and cannot detect and reject products with poor sealing in time, posing quality hazards.

[0005] Therefore, there is an urgent need for a bag - feeding bagging and sealing device with a real - time detection function to overcome the defects of the existing technology. Summary of the Utility Model

[0006] To overcome the problems in the related art, the purpose of the utility model is to provide a bag - feeding bagging and sealing device to solve the problem of inability to detect poor sealing in time in the existing technology.

[0007] A bag - feeding bagging and sealing device includes:

[0008] A first sealing component for sealing the packaging bag. A sealing detection component is arranged behind the first sealing component. The sealing detection component includes a pressure detection device for detecting the pressure at the sealing position of the packaging bag.

[0009] In some embodiments, a second sealing component is further arranged behind the pressure detection device. The second sealing component is used for re - sealing the packaging bag with poor sealing.

[0010] When the pressure monitoring device detects poor sealing of the packaging bag, the second sealing component can perform re - sealing treatment on the packaging bag with poor sealing, which can effectively improve the sealing quality of the bag - feeding bagging and sealing device, and at the same time reduce product loss caused by abnormal packaging.

[0011] In some embodiments, it further includes a bag clamping assembly. The bag clamping assembly enables the bag after sealing to pass through the pressure detection device. The pressure detection device includes an auxiliary wheel, a pressure detection roller, and a pressure sensing assembly. The auxiliary wheel and the pressure detection roller are oppositely arranged and closely attached to each other. The pressure detection roller is connected to the pressure sensing assembly. The bag clamping assembly enables the packaging bag to pass between the two pressure detection rollers.

[0012] The auxiliary wheel and the pressure detection roller form a pair of closely attached roller pairs, which can clamp the sealing part of the packaging bag. Through the connection between the pressure detection roller and the pressure sensing assembly, the pressure signal is transmitted to the pressure sensing assembly to realize the detection of the sealing pressure of the packaging bag.

[0013] In some embodiments, a transmission rod is further provided between the pressure detection roller and the pressure sensing assembly. One end of the transmission rod is rotatably connected to the pressure detection roller, and the other end is connected to the pressure sensing assembly.

[0014] In some embodiments, a vibration amplification assembly is further provided between the pressure sensing assembly and the transmission rod. The vibration amplification assembly is used to amplify the vibration of the pressure detection roller.

[0015] The function of the vibration amplification assembly is to amplify the weak pressure signal, which is convenient for the pressure sensing assembly to sense and process. By amplifying the pressure signal, the perception ability of the device to subtle pressure changes can be improved, and it is easier to identify the situation of poor sealing, further improving the detection accuracy.

[0016] In some embodiments, the vibration amplification assembly includes an amplification lever. One end of the amplification lever is fixedly connected to the transmission rod, and the other end is connected to the pressure sensing assembly. A fulcrum is provided on the side of the amplification lever close to the transmission rod.

[0017] Using the amplification lever to amplify the pressure signal can ensure the amplification effect. At the same time, since the signal is amplified by a mechanical structure, it can have good signal amplification stability and reliability.

[0018] In some embodiments, the pressure sensing assembly includes an electromagnetic coil and a movable rod. The movable rod is arranged inside the electromagnetic coil, and the movable rod is connected to the amplification end of the amplification lever.

[0019] Under the action of pressure, the movable rod moves inside the electromagnetic coil, generating a current associated with the movement intensity and outputting the pressure change in the form of an electrical signal, which is convenient for realizing automation.

[0020] In some embodiments, a guide plate is further provided in front of the pressure detection device. The guide plate gradually converges in the direction close to the roller.

[0021] The function of the guiding plate is to guide the packaging bag smoothly into the space between the two pressure detection rollers and ensure its correct position. The gradually converging design can effectively prevent the packaging bag from getting stuck or damaged, ensuring the accuracy of pressure detection.

[0022] In some embodiments, the pressure detection device further includes a signal processing module, which is electrically connected to the pressure sensing component. The signal processing module is used to receive the pressure signal sent by the pressure sensing component and determine whether the seal is qualified according to a preset pressure threshold.

[0023] After receiving the pressure signal sent by the pressure sensing component, the signal processing module compares it with the pre-set pressure threshold. If the pressure value is within the threshold range, it is determined that the seal is qualified; if the pressure value exceeds the threshold range, it is determined that the seal is unqualified. This automatic judgment method avoids the subjectivity and errors of manual judgment, improving the detection efficiency and accuracy.

[0024] In some embodiments, the signal processing module is electrically connected to a control unit, and the control unit is used to control the second sealing component to re-seal the packages determined to have poor seals.

[0025] The signal processing module transmits the seal quality detection result to the control unit, and the control unit controls the second sealing component to re-seal the packages with poor seals. This automatic control method eliminates the need for manual intervention, improves the automation level and production efficiency of the equipment, reduces labor costs, and ensures product consistency.

[0026] The beneficial effects of the present utility model are as follows:

[0027] The present utility model provides a bag - feeding bag - filling and sealing device, which includes a first sealing component and a pressure detection device. The surface of the seal of the package with a poor seal is uneven and the pressure fluctuates greatly. By detecting the pressure at the seal of the packaging bag after sealing through the pressure detection device, and by detecting the pressure value at the seal, it is judged whether the seal is good, and defective packages are detected in real - time, which is convenient for removing or re - sealing defective packages during subsequent processing, ensuring the seal quality of the package and effectively improving the detection efficiency of defective packages.

[0039] Embodiment 1

[0040] As Figures 1-4 shown, this embodiment provides a bag-feeding bagging and sealing device, and the bag-feeding bagging and sealing device includes

[0041] a first sealing component 100 for sealing a packaging bag, a sealing detection component 200 is provided behind the first sealing component 100, and the sealing detection component 200 includes a pressure detection device 210 for detecting the pressure at the sealing position of the packaging bag.

[0042] Specifically, a second sealing component 300 is further provided behind the pressure detection device 210, and the second sealing component 300 is used for re-sealing the packaging bag with poor sealing.

[0043] More specifically, both the first sealing assembly 100 and the second sealing assembly 300 can adopt a variety of heat sealing methods. For example, heat press sealing, where a heated pressing plate is used to press and seal the packaging bag; ultrasonic sealing, where heat generated by high-frequency vibration is used to weld the packaging bag; pulse sealing, where heat generated by pulsed current released in a short time is used to weld the packaging bag.

[0044] More specifically, the first sealing assembly 100 and the second sealing assembly 300 can adopt different heat sealing methods, or the same heat sealing method.

[0045] In this embodiment, the first sealing assembly 100 and the second sealing assembly 300 adopt a common heat sealing mechanism, and the openings of the packaging bag are fused together by heating to achieve the sealing function.

[0046] Specifically, it further includes a bag clamping assembly 400. The bag clamping assembly 400 enables the bag after sealing to pass through the pressure detection device 210. The pressure detection device 210 includes an auxiliary wheel 211, a pressure detection roller 212, and a pressure sensing component 213. The auxiliary wheel 211 and the pressure detection roller 212 are arranged opposite to each other and are in close contact. The pressure detection roller 212 is connected to the pressure sensing component 213. The bag clamping assembly 400 enables the packaging bag to pass between the two pressure detection rollers 212.

[0047] More specifically, the material of the auxiliary wheel 211 can be selected from wear-resistant and low-friction coefficient materials, such as nylon, polytetrafluoroethylene, etc.

[0048] Specifically, a transmission rod 214 is further provided between the pressure detection roller 212 and the pressure sensing component 213. One end of the transmission rod 214 is rotatably connected to the pressure detection roller 212, and the other end is connected to the pressure sensing component 213.

[0049] More specifically, the surface of the pressure detection roller 212 can be coated to improve the wear resistance of the pressure detection roller 212, reduce the surface friction of the pressure detection roller 212, and prevent the pressure detection roller 212 from damaging the packaging bag.

[0050] After the bag clamping assembly 400 clamps the packaging bag and passes it through the first sealing assembly 100 for initial sealing, it is conveyed to the pressure detection device 210. The auxiliary wheel 211 and the pressure detection roller 212 clamp the sealed part of the packaging bag. If the sealed part is flat, the pressure detection roller 212 remains stable; if there are unevennesses in the sealed part, the pressure detection roller 212 will vibrate accordingly with the uneven changes. The vibration of the pressure detection roller 212 is transmitted to the pressure sensing component 213 through the transmission rod 214, and the pressure sensing component 213 converts the mechanical vibration into an electrical signal for output.

[0051] Embodiment 2

The sealing detection component 200 includes a pressure detection device 210, and the pressure detection device 210 is used to detect the pressure at the sealed part of the packaging bag.

[0054] Specifically, a second sealing component 300 is further provided behind the pressure detection device 210, and the second sealing component 300 is used to re - seal the packaging bag with poor sealing.

[0055] In this embodiment, the first sealing component 100 and the second sealing component 300 adopt ultrasonic sealing, and the opening of the packaging bag is fused together by ultrasonic waves to achieve the sealing function.

[0056] Specifically, it further includes a bag - clamping component 400. The bag - clamping component 400 enables the sealed bag to pass through the pressure detection device 210. The pressure detection device 210 includes an auxiliary wheel 211, a pressure detection roller 212, and a pressure - sensing component 213. The auxiliary wheel 211 and the pressure detection roller 212 are arranged opposite to each other and are in close contact. The pressure detection roller 212 is connected to the pressure - sensing component 213, and the bag - clamping component 400 enables the packaging bag to pass between the two pressure detection rollers 212.

[0057] Specifically, a transmission rod 214 is further provided between the pressure detection roller 212 and the pressure - sensing component 213. One end of the transmission rod 214 is rotatably connected to the pressure detection roller 212, and the other end is connected to the pressure - sensing component 213.

[0058] More specifically, a vibration amplification component 220 is further provided between the pressure - sensing component 213 and the transmission rod 214, and the vibration amplification component 220 is used to amplify the vibration of the pressure detection roller 212.

[0059] More specifically, the vibration amplification component 220 can adopt various structures, which can be mechanical methods or electrical signal amplification methods.

[0060] More specifically, the structure of the transmission rod 214 can be designed according to actual needs. For example, it can adopt forms such as a straight rod or a bent rod to adapt to different spatial layouts. In this embodiment, the transmission rod 214 is of a straight - rod structure.

[0061] More specifically, the vibration amplification component 220 includes an amplification lever 221. One end of the amplification lever 221 is fixedly connected to the transmission rod 214, and the other end is connected to the pressure sensing component 213. A fulcrum is provided on the side of the amplification lever 221 close to the transmission rod 214.

[0062] Using the amplification lever 221 to amplify the pressure signal can ensure the amplification effect. At the same time, since the signal is amplified by a mechanical structure, it can have good signal amplification stability and reliability.

[0063] More specifically, the amplification multiple of the amplification lever 221 can be changed by adjusting the length ratio of the lever arms.

[0064] More specifically, the pressure sensing component 213 includes an electromagnetic coil 2131 and a movable rod 2132. The movable rod 2132 is arranged inside the electromagnetic coil 2131, and the movable rod 2132 is connected to the amplification end of the amplification lever 221.

[0065] Under the action of pressure, the movable rod 2132 moves inside the electromagnetic coil 2131, generating a current associated with the movement intensity and outputting the pressure change in the form of an electrical signal, which is convenient for realizing automation.

[0066] More specifically, in addition to the electromagnetic pressure sensing component 213, other types of sensors can also be used, such as piezoresistive sensors, which use the characteristic that the resistance value of a piezoresistor changes with pressure to measure pressure; capacitive sensors, which use the characteristic that the capacitance value changes with pressure to measure pressure.

[0067] More specifically, a guide plate is provided in front of the pressure detection device 210, and the guide plate gradually converges in the direction close to the roller.

[0068] More specifically, the guide plate is composed of two stainless steel plates arranged oppositely.

[0069] More specifically, the pressure detection device 210 further includes a signal processing module. The signal processing module is electrically connected to the pressure sensing component 213. The signal processing module is used to receive the pressure signal sent by the pressure sensing component 213 and judge whether the sealing is qualified according to a preset pressure threshold.

[0070] More specifically, the signal processing module can be implemented by using controller devices such as a single-chip microcomputer or a PLC, and the pressure threshold and judgment logic are set through programming.

[0071] More specifically, the signal processing module is electrically connected to the control unit, and the control unit is used to control the second sealing component 300 to reseal the packages determined to have poor sealing.

[0072] In this embodiment, the bag clamping assembly 400 clamps the packaging bag, which is ultrasonically sealed by the first sealing assembly 100, and then passes through the pressure detection device 210. The pressure detection roller 212 and the auxiliary roller 211 squeeze the sealed part of the packaging bag to detect the sealing pressure. If there are unevenness at the sealed part, the pressure detection roller 212 will generate vibrations, which are transmitted to the vibration amplification assembly 220 via the transmission rod 214. After amplifying the vibration signal, the vibration amplification assembly 220 transmits it to the pressure sensing assembly 213. The pressure sensing assembly 213 converts the mechanical vibration signal into an electrical signal and transmits it to the signal processing module. The signal processing module compares the pressure signal with a preset threshold value to determine whether the sealing is qualified. If it is determined that the sealing is qualified, the packaging bag is normally output; if it is determined that the sealing is unqualified, the control unit controls the second sealing assembly 300 to reseal the packaging bag.

[0073] The bag - feeding bag - filling and sealing equipment provided in this embodiment realizes real - time monitoring and automatic resealing of the packaging bag sealing quality by introducing the pressure detection device 210 and the second sealing assembly 300. During operation, the pressure detection device 210 can accurately measure the pressure change at the sealed part of the packaging bag and transmit the signal to the signal processing module for analysis and judgment. If an abnormal sealing pressure is detected, indicating that the sealing quality does not meet the standard, the signal processing module will transmit the information to the control unit, and the control unit drives the second sealing assembly 300 to automatically reseal the packaging bag. Thus, while ensuring the product sealing quality, it also avoids manual intervention and resource waste, effectively improving production efficiency and reducing production costs.
