Description

Technical Field

[0001] This invention relates to the field of temperature control technology for cutting devices, and in particular to a temperature control method, system, and cutting device for pulse cutting devices. Background Technology

[0002] The manufacturing of plastic bottle caps requires cutting tamper-evident rings. For example, the authorized patent CN112591300B uses a rolling cut method, where a bottle cap of a specific diameter is rolled around on a special blade, and the blade cuts through the bottle cap to form a slit. To improve the efficiency of cutting the tamper-evident rings on plastic bottle caps, the ring cutter needs to be actively heated to a preset temperature (e.g., 120°C~150°C) to soften the plastic and reduce frictional heat. However, the ring cutter needs to maintain a stable temperature during the cutting process. The additional heat generated by the friction between the blade and the bottle cap during cutting (approximately increasing the temperature by 10°C~30°C) can cause the plastic to overheat and melt.

[0003] In existing technologies, the temperature is typically controlled by treating the entire bottle cap cutting time as a cycle. This control method is not suitable for situations where heat from the circumferential cutting tool can be transferred to subsequent workstations.

[0027] In order to make the application purposes, features and advantages of the present application more obvious and easy to understand, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings of the embodiments of the present application. Obviously, the embodiments described below are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] The present application provides a temperature control method for a pulse cutting device to solve the problem of low efficiency of the temperature control method of the cutting device in the prior art, which affects the ring cutting quality of the bottle cap.

[0029] Please refer to Figure 1 , Figure 1 The first flowchart of a temperature control method for a pulse cutting device provided by the embodiments of the present application.

[0030] S100, obtaining ring cutting data, constructing a temperature detection time interval based on the ring cutting data; obtaining ring cutting knife temperature data corresponding to each temperature detection time interval;

[0031] It should be noted that the ring cutting data includes the number of cutting edges of the ring cutting knife, and the rotating speed of the ring cutting bottle cap or the linear speed to be maintained. Based on the speed, the length of time that each bottle cap passes through the ring cutting knife can be calculated. The length of time that each cutting edge cuts the bottle cap can be obtained by dividing the length of time by the number of cutting edges of the ring cutting knife, that is, the corresponding temperature detection time interval can be generated. For example, according to the rotating speed of the ring cutting bottle cap, the ring cutting time of each bottle cap is 0.2s. In the case that the number of cutting edges of the ring cutting knife is 10, the length of time of 0.2s can be divided into 10 temperature detection intervals, and the temperature detection time interval is constructed every 0.02s.

[0032] The pulse cutting device first heats the ring cutting knife according to the preset fixed pulse parameters, and the temperature data detection scene is generally the case that the cutting device is just started. Then, the temperature data is obtained according to the temperature detection time interval. A group of temperature data should correspond to the complete process of cutting a bottle cap on the ring cutting knife. The temperature data under each temperature detection time interval reflects the temperature change of the corresponding cutting edge when cutting the bottle cap.

[0033] S200, identifying the temperature change feature in the ring cutting knife temperature data, substituting the temperature change feature into the preset temperature control model, and generating the temperature control parameters corresponding to each temperature detection time interval;

[0034] It should be noted that the pulse cutting device uses pulse signals to control the opening and closing of solid-state relays, changing the working state of the heating rod within the pulse cycle to control the blade temperature. The circumferential cutting operation will only be performed when the temperature of the circumferential cutting blade reaches the preset temperature. Therefore, the preset pulse signal corresponds to the circumferential cutting blade being at the preset cutting temperature. However, the pulse signal is maintained throughout the circumferential cutting operation in the aforementioned steps. Therefore, the difference between the actual temperature of the circumferential cutting blade and the preset cutting temperature in each temperature detection time interval is the temperature change characteristic. At this time, the temperature on the circumferential cutting blade will change due to two factors: one is the frictional heat generated when the circumferential cutting blade cuts the bottle cap, and the other is the heat transfer caused by the temperature difference between the circumferential cutting blade and the bottle cap. The temperature change characteristic reflects the actual situation of these two factors.

[0035] Within each temperature detection time interval, the change in cutting temperature can be considered to conform to a preset temperature model, which is as follows:

[0036]

[0037] in, Temperature after cutting by the blade This refers to the temperature of the blade before cutting. Frictional heat To transfer heat, The specific heat of the blade is considered. Since the circumferential cutting blade is a single unit, typically made of metal, when one blade edge heats up during cutting, the entire blade can be considered to be at the same temperature. Therefore, when the thermocouple on the circumferential cutting blade detects the actual blade temperature during cutting at a particular edge, the overall temperature of the blade is consistent. The starting temperature for the next cutting edge should then be the actual blade temperature of the previous edge, i.e., the temperature detected after cutting by the previous edge. The temperature of the blade before the next cutting edge. In the calculation of the first cutting edge of the circumferential cutter, the temperature model should use the preset cutting temperature corresponding to the preset pulse signal as the temperature of the blade before cutting. In cutting PP / PE plastic bottle caps with low thermal conductivity, heat easily accumulates at the cut, with frictional heat being the dominant factor. Therefore, the accumulated frictional heat at each cut can be utilized to reduce the energy consumption of the cutting device. Furthermore, by reducing the duty cycle of the pulse signal, the pre-cutting temperature of the blade corresponding to each temperature detection time interval can be lowered, thus stabilizing the cutting temperature of each blade. This can be achieved based on a temperature model. The corresponding duty cycle adjustment parameters are set in part, and the heat reduction caused by reducing the duty cycle in each temperature detection time interval should be proportional to... The increased heat is consistent, generating corresponding temperature control parameters. In this embodiment, the blade heating is controlled by the pulse signal of the solid-state relay. Therefore, the temperature control parameter corresponds to the duty cycle. Due to the heat accumulation on the ring cutting blade, the duty cycle of the temperature control parameter corresponding to each temperature detection time interval decreases sequentially in time.

[0038] S300 sends temperature control parameters to the relay according to the temperature detection time interval.

[0039] It should be noted that the relay of the pulse cutting device in this embodiment is a solid-state relay. This type of relay is suitable for executing high-frequency pulse signals. In the aforementioned step S100, the data of the bottle cap passing through the cutting device is detected. In this step S300, the data is for the next bottle cap entering the cutting device. Based on the same circumferential cutting data, the corresponding temperature control parameters can be sent to the relay according to the corresponding cutting time period when the next bottle cap is cut. This allows the temperature of each cutting edge to utilize the frictional heat of the previous cutting edge, avoiding plastic melting and sticking due to excessive temperature. When the cutting edge temperature is stable, the hot melt cutting quality of the plastic bottle cap is optimal. While sending the temperature control parameters to the relay according to the temperature detection time interval, the thermocouple also detects the temperature of the circumferential cutting blade and substitutes it into the temperature control model in the aforementioned step S200 to correct the temperature control parameters again, forming a temperature control cycle, which further ensures the stability of the circumferential cutting blade temperature.

[0040] In this embodiment, the temperature detection time interval is set by acquiring the time period corresponding to each blade in the cutting device, and the corresponding temperature data is detected according to the time interval. The temperature control parameters are generated based on the accumulated heat of each blade reflected by the temperature change characteristics in the temperature data, and then sent to the relay according to the corresponding time interval to control the temperature of the next bottle cap cutting. This ensures that during the bottle cap ring cutting process, the temperature of the ring cutting blade can be guaranteed by maintaining the balance between the frictional heat rise and the heating rod temperature control cooling, avoiding high temperature cutting that causes plastic to melt and stick, affecting the ring cutting quality, and making full use of the cutting frictional heat to reduce the energy consumption of the ring cutting blade heating.

[0041] The above is a detailed description of the first embodiment of a temperature control method for a pulse cutting device provided in this application. The following is a detailed description of the second embodiment of a temperature control method for a pulse cutting device provided in this application.

[0042] In this embodiment, a temperature control method for a pulse cutting device is further provided. In the aforementioned step S200, the step of substituting the temperature change characteristics into a preset temperature control model to generate temperature control parameters corresponding to each temperature detection time interval specifically involves:

[0043] The temperature change characteristics are divided into input characteristics and output characteristics and substituted into the preset temperature control model. The preset temperature control model adopts a recurrent neural network model to learn the influence characteristics of each blade temperature on frictional heat and temperature difference heat dissipation, obtain the optimal temperature control heat difference of each blade, and generate the temperature control parameters corresponding to each temperature detection time interval.

[0044] It should be noted that the neural network model in this embodiment can be an RNN recurrent neural network model or an LSTM time-recurrent neural network model. The characteristic of this model is that it iterates through the node parameters, meaning that the starting temperature for the next cut of the ring cutter should be the actual blade temperature of the previous cut. Both the RNN and LSTM models have output and input layers, corresponding to the heating from frictional heat and the dissipation from thermal difference heat transfer. Since the ring cutter softens the plastic bottle cap after heating, the higher the ring cutter temperature within the temperature range, the better the softening effect, resulting in less frictional heat generated during cutting. Because the bottle cap itself has low heat transfer efficiency due to plastic, it can be considered that there is no heat transfer during the short ring cutting time. Therefore, the initial temperature of the bottle cap corresponding to different cuts is consistent, and the ring cutter temperature... The higher the temperature, the greater the temperature difference between the cut and the bottle cap, and the more heat is transferred. Therefore, the entire heat transfer process is in dynamic equilibrium. The recurrent neural network model needs to learn the heat changes at different ring-cutting blade temperatures through the temperature control parameters corresponding to each temperature detection time interval, further improving the accuracy of subsequent temperature control parameters and obtaining the optimal temperature control heat difference for each blade. That is, in this embodiment, the reduced duty cycle is not directly associated with the heat difference, but the influence of the blade temperature on the actual frictional heat and heat transfer after the duty cycle change is also considered, which improves the control accuracy of the temperature control parameters. Furthermore, starting from the second cut in the ring-cutting process, in addition to the heat generated by the ring-cutting blade cutting into the plastic bottle cap, there is also the frictional heat generated by the previous blade retracting from the bottle cap. Input nodes can be further set in the recurrent neural network model for learning.

[0045] Furthermore, in the aforementioned step S300, before sending the temperature control parameters to the relay according to the temperature detection time interval, the following steps are also included:

[0046] The bottle cap entry time interval is calculated based on the ring cutting data. After the temperature detection time length following the last segment of temperature control parameters sent for the previous bottle cap cutting, a preset temperature control parameter is sent to the relay, and this temperature control parameter corresponds to the bottle cap entry time interval.

[0047] It should be noted that the circumferential cutting data also includes the distance between the two bottle cap positions entering the cutting device. The bottle cap entry time interval can be calculated based on data such as rotation speed. This time interval corresponds to the time difference of the temperature control parameters between the two bottle caps, that is, the length of time between the end of the pulse signal for executing the temperature control parameters when the last blade of the bottle cap is cut and the start of the temperature control parameters when the first blade of the next bottle cap is cut. The temperature control module controls the timing of the pulse signal transmission. Therefore, there is a bottle cap entry time interval between the pulse signal transmission time corresponding to the last blade cut and the pulse signal transmission time of the first blade cut of the next bottle cap, during which no frictional heat is generated. At this time, the temperature can be controlled according to the pulse signal of the preset temperature control parameters to keep the temperature of the circumferential cutting blade stable even when there is no cutting operation.

[0048] The above is a detailed description of a temperature control method for a pulse cutting device according to the first aspect of this application. The following is a detailed description of an embodiment of a temperature control system for a pulse cutting device according to the second aspect of this application.

[0049] Please see Figure 2 , Figure 2 This is a structural diagram of a temperature control system for a pulse cutting device. This embodiment provides a temperature control system for a pulse cutting device, including:

[0050] Temperature data acquisition module 10 is used to acquire circumferential cutting data, construct temperature detection time intervals based on circumferential cutting data, and acquire circumferential cutting blade temperature data corresponding to each temperature detection time interval.

[0051] The temperature control parameter generation module 20 is used to identify the temperature change characteristics in the ring cutting knife temperature data, substitute the temperature change characteristics into the preset temperature control model, and generate the temperature control parameters corresponding to each temperature detection time interval.

[0052] Temperature control module 30 is used to send temperature control parameters to the relay according to the temperature detection time interval.

[0053] Furthermore, in the temperature control parameter generation module 20, the temperature change characteristics are substituted into a preset temperature control model to generate temperature control parameters corresponding to each temperature detection time interval, specifically:

[0054] The temperature change characteristics are divided into input characteristics and output characteristics and substituted into the preset temperature control model. The preset temperature control model adopts a recurrent neural network model to learn the influence characteristics of each cutting edge temperature on frictional heat and temperature difference heat dissipation, obtain the optimal temperature control heat difference of each cutting edge, and generate the temperature control parameters corresponding to each temperature detection time interval.

[0055] Furthermore, before sending temperature control parameters to the relay according to the temperature detection time interval, the temperature control module 30 also includes:

[0056] The bottle cap entry time interval is calculated based on the ring cutting data. After the temperature detection time length following the last segment of temperature control parameters sent for the previous bottle cap cutting, a preset temperature control parameter is sent to the relay, and this temperature control parameter corresponds to the bottle cap entry time interval.
