[0002] When injection molded products are produced, the injection molding machine needs to melt the injection molding materials under high temperature and high pressure conditions and inject them into the mold. Since it takes a certain amount of time to heat and melt the injection molding materials, in order to improve the processing efficiency of the injection molding machine and ensure the production progress, the injection molding materials are usually preheated before being added to the injection molding machine. At present, the preheating of injection molding materials is mainly completed by an external oven or an on-board feeding container. The heat energy used in both comes from the conversion of electrical energy, which not only increases the additional power loss, but also increases the cost of preheating treatment. Among them, the amount of injection molding materials heated by the on-board feeding container at a time is very limited, which is not only inefficient, but also further increases the consumption of electrical energy. Therefore, there is an urgent need for a pretreatment system that can complete the preheating treatment of injection molding materials and reduce energy consumption and processing costs.

DETAILED DESCRIPTION

[0031] The technical solution of the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments, so that the advantages and features of the utility model can be more easily understood by those skilled in the art. Obviously, the embodiments described in this application are only part of the embodiments of the application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application.

[0032] See also Figure 1 An injection molding machine cooling water waste heat circulation system is shown, including an injection molding machine cooling device and an injection molding raw material pretreatment device. Among them, the injection molding machine cooling device includes an injection molding machine cooling tube group, and the injection molding machine cooling tube group is arranged in the cooling area of ​​the injection molding machine and is used to cool the cooling area. By cooling the injection molding machine through the injection molding machine cooling tube group, it is possible to prevent the injection molding machine from overheating and ensure that the injection molding machine can work normally. The injection molding machine cooling tube group can also cool the injection molded product to help the product cool and form. The injection molding raw material pretreatment device includes a hopper 1 and a heat exchange component 2. The hopper 1 has a storage cavity 10 for storing injection molding raw materials, and the heat exchange component 2 is configured to feed heat exchange gas into the storage cavity 10. The heat exchange gas can heat the injection molding raw materials in the storage chamber 10, which can not only dry the injection molding raw materials and eliminate moisture in the injection molding raw materials, but also preheat the injection molding raw materials before entering the injection molding machine, thereby saving part of the electric energy required for the injection molding machine to heat and melt the injection molding raw materials, thereby achieving energy-saving effect.

[0033] The cooling pipe group of the injection molding machine has a first pipe opening and a second pipe opening. The cooling water flows through the cooling area through the first pipe opening and is discharged from the second pipe opening. When the cooling water flows through the cooling area, the heat of the injection molding machine or the product will be transferred to the cooling water, and as the cooling water circulates away, the heat will also be taken away, thereby achieving a cooling effect. After this process, the temperature of the cooling water will rise, usually reaching 60-70℃, and there is considerable heat energy that can be utilized.

[0034] The heat exchange component 2 includes a water circulator 21 and a circulation fan 22. The water circulator 21 is arranged on the air supply path of the circulation fan 22. The water circulator 21 is used to provide heat, and it can transfer heat energy to the surrounding air and increase the temperature of the surrounding air. The circulation fan 22 can send the heated air into the storage chamber 10, and the gas sent in is the heat exchange gas. The water circulator 21 has a water inlet and a water outlet, and a circulation pipe 211 connected between the water inlet and the water outlet, wherein the water inlet is connected to the second pipe mouth, so that the cooling water heated by the cooling treatment of the injection molding machine cooling tube group can be transferred to the injection molding machine raw material pretreatment device to provide heat energy, thereby effectively utilizing the heat energy of the cooling water, that is, the waste heat of the injection molding machine and the injection molding machine cooling tube group, realizing the recycling of energy, not only saving energy, but also saving costs.

[0035] Take a certain injection molding factory as an example to calculate the thermal energy. The factory has 20 injection molding machines: the cooling water temperature difference is measured to be about 30°C. The preheating treatment device of each injection molding machine in the factory consumes 57.4kWh of electricity when working for 24 hours. The total energy consumption of the preheating treatment device in the injection molding factory working for 24 hours is 1148kWh.

[0036] The specifications of the circulating water pump in the plant show that the flow rate is 12.5m 3 / h; also calculated in 24 hours, the total mass of cooling water can be obtained. Knowing the specific heat capacity of water and the measured temperature difference, the thermal energy of water can be obtained according to the formula:

[0037] Q=cmΔT

[0038] Where Q is the thermal energy of circulating water; c is the specific heat capacity of water; m is the total mass of circulating water when the pump works for 24 hours; ΔT is the temperature difference of circulating water.

[0039] After calculation, the heat energy of cooling water is 3.78×10 10 J, the converted energy consumption of the preheating treatment device is 4.13×10 9 J, it can be seen that the heat energy provided by the circulating water is sufficient to meet the needs of heat treatment.

[0040] In this embodiment, see Figures 2 to 6As shown, the injection molding raw material pretreatment device also includes a mounting seat 3, the mounting seat 3 has a mounting cavity 30, an air supply port 311 and an air outlet 321, the air supply port 311 is arranged on the side of the mounting seat 3 and communicates with the mounting cavity 30, and the air outlet 321 is arranged on the end of the mounting seat 3. The accumulator 1 is arranged in the mounting cavity 30 and is located between the air supply port 311 and the air outlet 321, the heat exchange component 2 is installed on the mounting seat 3, and heat exchange gas is fed into the mounting cavity 30 through the air supply port 311. When performing the pretreatment operation, the heat exchange component 2 transports the heat exchange gas into the mounting cavity 30 through the air supply port 311, and the heat exchange gas can fill the storage cavity 10 of the accumulator 1, so that the injection molding raw material and the heat exchange gas fed are fully mixed and achieve sufficient heat exchange, and the gas after the heat exchange can be discharged from the air outlet 321. Setting the air outlet 321 at the end is conducive to the heat exchange gas filling the entire installation cavity 30. Preferably, the size of the air outlet 321 is smaller than the size of the air supply port 311, so that the heat exchange gas can better fill the entire installation cavity 30 and can more fully exchange heat energy.

[0041] See also Figures 3 to 6 As shown, the circumferential side wall of the accumulator 1 is densely covered with through holes 11 penetrating in the thickness direction, and all the through holes 11 are interconnected with the storage cavity 10, so that the heat exchange gas fed into the installation cavity 30 can enter the storage cavity 10 from the through holes 11. Specifically, the aperture of the through hole 11 is smaller than the size of the injection molding raw material, thereby preventing the injection molding raw material from entering the installation cavity 30 through the through hole 11. By increasing the number of through holes 11 and arranging the through holes 11 closely, it is convenient for the heat exchange gas to enter the storage cavity 10, thereby improving the heat exchange efficiency.

[0042] See also Figure 3 , Figure 6 As shown, in this embodiment, the accumulator 1 is conical, and the accumulator 1 has a first end 1a and a second end 1b which are arranged at two different ends in the length direction of the accumulator 1. In the direction perpendicular to the length extension of the accumulator 1, the cross-sectional size of the first end 1a is larger than the cross-sectional size of the second end 1b, wherein the first end 1a and the second end 1b are respectively fixed on the mounting seat 3, and the first end 1a is arranged closer to the air outlet 321 than the second end 1b. Specifically, in this embodiment, the accumulator 1 is arranged in a cone shape with a wide top and a narrow bottom, and the air outlet 321 is located at the upper end of the mounting seat 3. Such an arrangement not only facilitates the injection molding raw materials to be added into the storage cavity 10 from the top, but also facilitates the injection molding raw materials to be discharged from the bottom. At the same time, such an arrangement increases the stacking height of the injection molding raw materials, thereby increasing the area of ​​direct contact with the heat exchange gas blown directly from the side. In this embodiment, the air outlet 321 and the first end 1a are located on the same side, which increases the contact probability and contact time between the heat exchange gas and the injection molding material located at the first end 1a, thereby ensuring that the injection molding material and the heat exchange gas can perform sufficient heat exchange.

[0043] In this embodiment, the mounting base 3 includes a shell 31 and a cover 32. An opening 31a is provided at one end of the shell 31. The cover 32 can be cooperatively covered on one end of the shell 31 and covers the opening 31a. The air supply port 311 is provided on the side of the shell 31, and the air outlet 321 is provided on the cover 32. The hopper 1 is fixedly installed in the shell 31, and the first end 1a is adapted to the opening 31a. Specifically, see Figure 6 As shown, the opening 31a is arranged at the upper part of the housing 31, and the cover 32 can be arranged on the upper part of the housing 31. When loading materials into the storage cavity 10, the cover 32 needs to be removed from the upper part of the housing 31 first, and then the injection molding raw materials are added into the storage cavity 10. In this embodiment, the cover 32 is a prism shape with a size gradually decreasing from bottom to top, and the air outlet 321 is arranged at the upper part of the cover 32, so that the gas discharge is guided, so that the gas is convenient to be discharged outside the installation cavity 30.

[0044] In this embodiment, a shielding member (not shown in the figure) is provided above the cover body 32. The shielding member is located on the air outlet path and covers the entire air outlet 321. The shielding member is provided with air outlet holes for gas to pass through. At the same time, the shielding member can prevent the injection molding material from flying out of the air outlet 321. The shielding member can be fixedly connected to the cover body 32. In some embodiments, the shielding member can also be detachably connected to the cover body 32. When performing the pre-treatment operation, the shielding member and the cover body 32 are fixed to each other.

[0045] In this embodiment, the mounting seat 3 includes a plurality of mounting plates 312 sequentially connected along the circumferential direction, and the accumulator 1 has a plurality of baffles 12 sequentially connected along the circumferential direction, the number of baffles 12 and the mounting plates 312 are consistent and one-to-one corresponding, each mounting plate 312 is provided with an air supply port 311, the air supply port 311 penetrates the mounting plate 312 along the thickness direction, and each air supply port 311 corresponds to a baffle 12. Specifically, see Figure 6 As shown, in this embodiment, the mounting seat 3 is provided with four mounting plates 312, which are connected in sequence along the circumference to form the side of the shell 31. The storage container 1 is in the shape of a quadrangular pyramid, and has four baffles 12 connected in sequence along the circumference, and the four baffles 12 correspond to the four mounting plates 312. Such a configuration increases the area in which the injection molding raw material in the storage cavity 10 is in direct contact with the heat exchange gas.

[0046] In this embodiment, see Figure 3 , Figure 4 As shown, the baffle 12 is connected to the mounting plate 312 at the first end 1a, and the baffle 12 and the mounting plate 312 are arranged at an angle, and the angle formed between the two is an acute angle. In this way, the heat exchange gas needs to pass through the first end 1a of the accumulator 1 when flowing to the air outlet 321, thereby improving the utilization rate of the heat exchange gas.

[0047] In this embodiment, a group of heat exchange components 2 are installed at each air outlet 311, wherein the heat exchange components 2 are fixed on the mounting plate 312 and located outside the mounting seat 3. Such a configuration increases the flow rate of the heat exchange gas sent into the mounting cavity 30 and improves the efficiency of heat exchange. Figure 7 As shown, in this embodiment, four groups of heat exchange components 2 are provided.

[0048] In this embodiment, the water circulator 21 is provided with a housing 212, the circulation pipe 211 is arranged in the housing 212, and the circulation fan 22 is fixedly arranged on a side of the housing 212 away from the mounting seat 3. Along the extension direction of the air outlet path of the circulation fan 22, the housing 212 is provided with a perforation, which is connected to the air outlet 311, so that the heat exchange gas can enter the mounting cavity 30.

[0049] See also Figure 8 As shown, in this embodiment, the circulation pipe 211 is bent in the housing 212, and multiple circulation pipes 211 are arranged at intervals in the up-down direction, and multiple groups of circulation pipes 211 are arranged along the extension direction of the air outlet path of the circulation fan 22, so as to provide sufficient heat energy. In this embodiment, the circulation pipe 211 is a finned tube, so that heat exchange between the cooling water in the circulation pipe 211 and the external air is facilitated.

[0050] In some embodiments, each group of heat exchange components 2 is provided with a separate water outlet, and the water outlets of all heat exchange components 2 converge together after extending a certain distance. In another embodiment, the circulation pipes 211 of all heat exchange components 2 are interconnected and share one water outlet.

[0051] In this embodiment, the other end of the housing 31 is provided with a connecting port 313 and a valve (not shown in the figure) for closing and opening the connecting port 313, and the second end 1b of the accumulator 1 is installed in the connecting port 313. When feeding into the storage chamber 10, the valve is closed to prevent the injection molding material from leaking out from the connecting port 313. In the process of pre-treating the injection molding material, the valve is still closed, and while preventing the injection molding material from leaking out, it can also prevent the heat exchange gas from being discharged from the connecting port 313, so that during the pre-treatment, the heat exchange gas fed in from the air supply port 311 can only be discharged from the air outlet 321. After the pre-treatment is completed, the valve can be opened and the injection molding material that has undergone the pre-treatment can be transferred to the injection molding machine for processing. In this embodiment, the pre-treatment system also includes a feeding device, which is connected between the accumulator 1 and the injection molding machine, and is used to transfer the injection molding material in the accumulator 1 to the processing area of ​​the injection molding machine.

[0052] In this embodiment, the cooling device of the injection molding machine further includes a cooling tower, and the pretreatment system further includes a pipeline assembly and a temperature detector. The cooling tower is configured to cool water, wherein the cooling tower is connected to the first pipe opening. The pipeline assembly includes a first pipeline connecting the water outlet and the cooling tower, and a second pipeline connecting the water outlet and the first pipe opening, a first switch provided on the first pipeline and used to control the on-off of the first pipeline, a second switch provided on the second pipeline and used to control the on-off of the second pipeline, and a control element for switching the working state of the first switch and the second switch. The temperature detector is provided at the water outlet and used to detect the temperature of the water flowing out of the water outlet, and the temperature detector is communicatively connected to the control element.

[0053] After the cooling water transfers heat to the air through the water circulator 21, its temperature will decrease. When it is discharged from the water outlet, its temperature is first measured by the temperature detector. When its temperature does not exceed the preset value, the temperature detector sends a signal to the control element, and the control element controls the second switch to open. At this time, the second pipeline is connected, and the water can flow into the first pipe mouth through the second pipeline, that is, enter the injection molding machine cooling pipe group again and cool the injection molding machine. In this way, the first cycle is formed and the cooling water is recycled. When the temperature detector detects that the temperature of the water flowing out of the water outlet exceeds the preset value, the temperature detector sends another signal to the control element. After receiving the signal, the control element controls the first switch to open. At this time, the first pipeline is connected, and the outflowing water flows along the first pipeline into the cooling tower for cooling and cooling, and then flows into the first pipe mouth, thus forming the second cycle.

[0054] By setting up two pipelines and using a temperature detector and a control element connected by communication to divert the water flowing out of the outlet, it is not necessary to pass all the water flowing out of the outlet into the cooling tower for cooling, and the cooling tower does not need to be in working condition all the time, thereby saving the electricity of the cooling tower.

[0055] In summary, the injection molding raw material pretreatment device of the present embodiment is provided with a water circulator 21. By passing hot water into the water circulator 21, the hot water exchanges heat with the air around the water circulator 21. Under the action of the circulating fan 22, the heated air forms hot air and is blown into the storage chamber 10. The hot air exchanges heat with the injection molding raw material in the storage chamber 10, thereby achieving the effect of preheating the injection molding raw material. In this way, no additional electric energy is required when preheating the injection molding raw material. At the same time, in the cooling water waste heat circulation system of the injection molding machine of the present embodiment, the cooling water heated by the cooling treatment can flow into the water circulator 21, and the cooling water provides heat energy for the injection molding raw material pretreatment device, which not only saves energy and reduces costs, but also the heat exchange component 2 realizes the utilization of the heat energy carried by the cooling water, and uses the heat energy to preheat the injection molding raw material, realizing the recycling of energy, improving the utilization rate of energy, and more in line with environmental protection requirements.

[0056] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
