[0002] A bottle making machine is a mechanical equipment used to manufacture glass bottles. The bottle making machine generally includes a feeder and multiple molding machines. The molten glass droplets are sent to the molding machines by the feeder. The molding machine is generally equipped with one or more sets of primary molds and molding molds corresponding to the primary molds. After the glass droplets form a primary embryo body in the primary mold, the primary embryo body is transferred to the molding mold for final molding.

[0003] In the whole bottle making process, the change of the temperature of the primary mold of the bottle making machine plays a decisive role in the quality of glass bottle molding. In the existing technology, the temperature of the primary mold is controlled by the plug-in plate installed on the nozzle seat on both sides of the mold. The operator manually adjusts the cooling air volume and controls the mold temperature based on intuition and experience, resulting in a large deviation between the actual temperature and the ideal molding temperature, and only low-grade products can be produced, which cannot meet the quality requirements of users for high-end glass bottles.

[0004] The Chinese utility model patent with application number 201621208602.7 and application date November 9, 2016, and patent name “Cooling temperature control system for primary mold of bottle making machine” discloses a technical solution, in which a thermocouple is installed in the primary mold to monitor the cooling temperature of the primary mold, and the control of the cooling gas delivery channel is achieved through the control unit, so as to ensure the constant temperature of the primary mold, thereby improving the product quality. However, in this technical solution, it is only mentioned that a thermocouple is set in the primary mold, but the specific technical solution for setting the thermocouple is not recorded. Therefore, designing a specific technical solution that can realize the setting of the thermocouple in the primary mold has become an urgent problem to be solved in this field. Utility Model Content

[0005] The technical problem to be solved by the utility model is: to overcome the deficiencies of the prior art and to provide a primary mold temperature measuring device for a bottle making machine, which is configured by arranging a thermocouple in a cavity between the primary mold clamp and the primary mold monomer, the thermocouple being in close contact with the primary mold monomer, thereby realizing monitoring of the temperature of the primary mold monomer, facilitating precise control of the temperature of the primary mold, and further improving product quality.

[0006] The technical solution adopted by the utility model to solve the technical problem is: the primary mold temperature measuring device for the bottle making machine includes a thermocouple installed at the primary mold of the bottle making machine, the primary mold includes two relative primary mold monomers, and is characterized in that: a primary mold clamp is fixed on the outside of each primary mold monomer, the thermocouple is installed in a cavity formed by the primary mold monomer and the primary mold clamp, the thermocouple probe at the end of the thermocouple is fitted with the primary mold monomer, and the thermocouple lead at the tail of the thermocouple is led out from the primary mold clamp.

[0007] Preferably, a mounting hole is provided in the primary mold clamp, a temperature measuring hole opposite to the mounting hole is provided in the primary mold unit, the thermocouple passes through the mounting hole, and the thermocouple probe enters the temperature measuring hole.

[0008] Preferably, the temperature measuring hole is a blind hole, and the thermocouple probe is closely attached to the end of the temperature measuring hole.

[0012] Preferably, a handle is provided at the end of the mounting hole in the primary mold clamp facing away from the primary mold unit, a slot is provided at the tail of the thermocouple, and a retaining ring is installed at the slot after the thermocouple lead wire is led out from the primary mold clamp.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In the initial mold temperature measuring device for the bottle making machine, a thermocouple is arranged in the cavity between the initial mold clamp and the initial mold monomer, and the thermocouple is close to the initial mold monomer, so that the temperature of the initial mold monomer is monitored, which is convenient for accurate control of the temperature of the initial mold and further improves the quality of the product.

[0016] In the initial mold temperature measuring device for the bottle making machine, under the premise that the initial mold clamp and the initial mold of the original bottle making machine remain unchanged, a set of special thermocouples with sheaths and a universal temperature control instrument are added to form a closed-loop automatic mold temperature control, which is conducive to improving the existing bottle making machine.

DETAILED DESCRIPTION

[0022] Figures 1 to 3 It is the best embodiment of the utility model, and the following Figures 1 to 3 The utility model is further described.

[0023] like Figure 1~2 As shown, a blank mold temperature measuring device for a bottle making machine (hereinafter referred to as a temperature measuring device) includes a temperature measuring mechanism 5 installed in a blank mold clamp 4 on the blank mold side of the bottle making machine. As in the prior art, a blank mold support 2 is provided on the blank mold side, and the blank mold clamp 4 is swingably provided on both sides of the blank mold support 2.

[0024] A primary mold monomer 6 is fixed to the inner side of the primary mold clamps 4 on both sides, and the primary mold monomers 6 on both sides are closed or separated under the action of the corresponding primary mold clamps 4. When the primary mold monomers 6 on both sides are closed, the material drops into the primary mold to form a primary mold body. When the primary mold monomers 6 on both sides are separated, the primary mold body can be transferred to the molding side. The technical solution adopted by the primary mold clamps 4 to drive the primary mold monomer 6 to move is common knowledge in the field and will not be repeated here.

[0025] The temperature measuring mechanism 5 is arranged between each primary mold unit 6 and the corresponding primary mold clamp 4, and a connector 3 corresponding to each temperature measuring mechanism 5 is arranged on the primary mold bracket 2, and a temperature controller 1 corresponding to each temperature measuring mechanism 5 is also arranged on the back side of the primary mold bracket 2, and the signal output end of each temperature measuring mechanism 5 is connected to the corresponding temperature controller 1 through the corresponding connector 3. The signal output end of the temperature controller 1 is connected to the PLC of the bottle making machine, and the PLC judges the temperature data collected by the temperature measuring mechanism 5. If the preset temperature value is less than the current temperature data of the primary mold unit 6, the controller controls the electrical valve box and the air door solenoid valve to extend the air supply time; when the preset temperature value is greater than the current temperature data of the primary mold unit 6, the air door solenoid valve shortens the air supply time.

[0026] Combination Figure 3 A through-mounting hole 14 is provided in the primary mold clamp 4, and a temperature measuring hole 9 corresponding to the mounting hole 14 is provided on the outer wall of the primary mold monomer 6. The temperature measuring hole 9 is a blind hole. After the primary mold clamp 4 is fixed to the primary mold monomer 6, the mounting hole 14 and the temperature measuring hole 9 are coaxial inside and outside. The thermocouple is placed in the primary mold clamp 4, and the thermocouple probe 10 at the end of the thermocouple enters the temperature measuring hole 9. The thermocouple lead 7 at the end of the thermocouple is led out from the outer surface of the mounting hole 14 and connected to the above-mentioned connector through a wire.

[0027] A retaining ring 11 is coaxially sleeved on the outer ring of the end of the thermocouple, and a guide sleeve 12 is installed on the inner wall of the mounting hole 14. The guide sleeve 12 is located at the end of the mounting hole 14 facing the primary mold monomer 6. The retaining ring 11 is connected to the thermocouple on the inner side thereof and passes through the guide sleeve 12, and the retaining ring 11 is fixed to the guide sleeve 12.

[0028] An annular boss is formed inwardly at the port of the guide sleeve 12 facing the primary mold monomer 6, and the retaining ring 11 is installed on the inner side of the annular boss at the end of the guide sleeve 12. After the retaining ring 11 and the guide sleeve 12 are fixedly installed, an annular interlayer is formed between the guide sleeve 12 and the retaining ring 11. A spring 13 is also provided in the primary mold clamp 4. The spring 13 is sleeved on the outside of the thermocouple. One end of the spring 13 is located at the end of the mounting hole 14, and the other end enters the interlayer between the guide sleeve 12 and the retaining ring 11, and uses its own thrust to keep the thermocouple moving toward the primary mold monomer 6, so that the thermocouple probe 10 is close to the end of the temperature measuring hole 9.

[0029] A handle 8 is also provided at the port of the primary mold clamp 4 on the side facing away from the primary mold monomer 6, and an annular groove is provided at the tail end of the thermocouple. The thermocouple and the thermocouple lead 7 at its tail are led out from the mounting hole 14 and pass through the handle 8. A retaining ring 15 is installed in the groove at the tail of the thermocouple. By providing the retaining ring 15, the thermocouple is prevented from being ejected from the mounting hole 14 under the action of the spring 13.

[0030] The specific working process and working principle are as follows:

[0031] The primary mold monomers 6 on both sides are closed or separated under the action of the corresponding primary mold clamps 4. When the primary mold monomers 6 on both sides are closed, the material drops into the primary mold to form a primary embryo body. When the primary mold monomers 6 on both sides are separated, the primary embryo body can be transferred to the molding side.

[0032] During the operation of the primary mold, the thermocouples installed in the primary mold monomers 6 on both sides respectively monitor the temperature in the primary mold monomers 6 on both sides in real time, and send the monitored temperature values ​​to the corresponding temperature controller 1 through wires and connectors. The temperature controller 1 further sends the monitored temperature data to the PLC of the bottle making machine. The PLC judges the temperature data collected by the temperature measuring mechanism 5. If the preset temperature value is less than the current temperature data of the primary mold monomer 6, the controller controls the electrical valve box and the air door solenoid valve to extend the air supply time; when the preset temperature value is greater than the current temperature data of the primary mold monomer 6, the air door solenoid valve shortens the air supply time, thereby realizing the monitoring of the temperature of the primary mold.

[0033] When the thermocouple needs to be replaced, after separating the primary mold unit 6 from the primary mold clamp 4, first remove the retaining ring 15, and then push the thermocouple to the side of the primary mold unit 6 under the action of the spring 13, remove the retaining ring 11 and the thermocouple from the guide sleeve 12, and separate the retaining ring 11 from the thermocouple, install the newly replaced thermocouple and retaining ring 11, and then re-install them into the guide sleeve 12, and then send the guide sleeve 12 and the retaining ring 11 and the thermocouple inside it into the mounting hole 14 again to complete the replacement of the thermocouple.

[0034] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
