Description

Technical Field

[0001] The utility model relates to the technical field of PE packaging bag processing, and more specifically, to a cooling device for a blow molding machine used for PE packaging bag processing. Background Art

[0002] Blow molding machine is a kind of equipment used to make plastic products. It heats the molten plastic particles to the melting temperature, injects them into the mold, and blows the plastic into shape by air pressure to make various plastic products.

[0003] In order to make plastic products have better dimensional stability and surface quality, it is usually necessary to cool them to control the cooling speed and solidification process of the plastic. The current cooling device, for example, application number: CN202123114222.0, a blow molding machine molding cooling device, includes a base, a drive block and a diversion pipe, a water tank and a cooling box are respectively installed on the top of the base, a water inlet is opened at the top of the water tank, a stirring mechanism is installed inside the water tank, one side of the water tank is connected to a water pipe, a water pump is installed on the water pipe, and the end of the water pipe away from the water tank is connected to a hose, a feed inlet is opened on one side of the cooling box, a horizontal drive mechanism is provided inside the cooling box, an angle adjustment mechanism is provided at the bottom end of the drive block, and a plurality of nozzles are installed at the bottom end of the diversion pipe.

[0004] The device uses a horizontal drive mechanism and an angle adjustment mechanism to cool the product over a large area. However, the newly formed plastic products are usually at a high temperature and have poor stability, and need to be cooled for shaping. Although the flushing of water flow can effectively cool down, too strong water flow will also damage the structure of the plastic product, causing it to deform, affecting the production quality. In addition, the plastic products manufactured by the blow molding machine are usually hollow. The operation of the nozzle will cause the water source to spray into the interior of the plastic product. At this time, it needs to be cleaned and dried before it can be collected. In addition, the water flow on the surface will also be stained, making collection more difficult. Therefore, it needs to be improved and optimized. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] like Figures 1 to 7 As shown, the utility model provides a cooling device for a blow molding machine for processing PE packaging bags, comprising a support platform 1, an injection molding machine 2 is fixedly installed on the top of the support platform 1, a blow molding device 3 is fixedly installed on the top of the support platform 1, and a moving rod 4 is fixedly installed on the bottom of the support platform 1;

[0033] The plastic film mechanism is movably mounted on the top of the support platform 1 and movably sleeved with the moving rod 4;

[0034] The heat dissipation mechanism is fixedly installed on the top of the plastic film mechanism;

[0035] The ventilation mechanism is fixedly installed inside the plastic film mechanism and is interconnected with the heat dissipation mechanism;

[0036] The driving mechanism is fixedly mounted on the back of the heat dissipation mechanism, and one end of the driving mechanism is meshed with the ventilation mechanism;

[0037] Among them, the driving mechanism includes a shell 15 fixedly installed on the back of the heat dissipation mechanism, a motor 16 is fixedly installed inside the shell 15, the output shaft of the motor 16 is fixedly connected to the driving block 17, one end of the driving block 17 is movably installed inside the transmission rod 19, the transmission rod 19 is movably installed inside the fixed block 18, there are two groups of fixed blocks 18, both of which are fixedly installed inside the shell 15, and the transmission rod 19 and one end of the ventilation mechanism are meshed with each other.

[0038] When blow molding is required, the staff first ensures that there is enough coolant stored in the cooling box 7 and that the water valve of the water pipe 25 operates normally to circulate the coolant. Then, the PE material is filled into the injection molding machine 2 and the front mold 5 and the rear mold 6 are closed. At this time, the injection molding machine 2 injects the melted material into the front mold 5 and the rear mold 6. Then, the staff moves the front mold 5 and the rear mold 6 to the bottom of the blow molding machine 3 to start the blow molding machine 3. Then, the staff can start the motor 10 and the motor 2 16. The operation of the motor 10 is started. The fan blades 12 are driven to rotate. The fan blades 12 filter the outside air through the filter plate 9, and then blow it into the interior of the cooling box 7 through the guide hole 14 to cool the coolant inside. Then, the operation of the motor 16 drives the driving block 17 to rotate. The rotation of the driving block 17 drives the transmission rod 19 to move. At this time, the transmission rod 19 is restricted by the two groups of fixed blocks 18, so that it moves left and right, and the transmission rod 19 and the gear 20 are engaged with each other, causing the guide hole 14 to start swinging left and right, which assists in cooling the coolant inside the cooling box 7, thereby improving the cooling efficiency.

[0039] Through the cooperation of the front mold 5 and the rear mold 6, the PE material is plasticized, and then the plastic product and the mold are cooled through the circulation cooperation of the guide hole 14 and the water pipe 25. At the same time, the operation of the motor 10 and the motor 2 16 drives the guide hole 14 to perform ventilation and heat dissipation operations. Compared with the traditional device, the device completes the cyclic cooling through the cooperation of the plastic film mechanism and the water pipe 25, and then cools the coolant inside the cooling box 7 through the driving and ventilation mechanism, so that the plastic product can complete the heat dissipation without contacting with the direct current water, avoiding the cleaning of the mold after the heat dissipation is completed, and can also avoid the deformation of the mold caused by the water flow, ensuring the production quality while improving the cooling efficiency.

[0040] Among them, a fixing groove 21 is fixedly installed at one end of the plastic film mechanism;

[0041] An extrusion mechanism, movably mounted inside the fixing groove 21;

[0042] The extrusion mechanism includes a baffle 22 movably mounted inside the fixed groove 21 , the baffle 22 and the ejector pin 23 are fixedly connected, and one end of the ejector pin 23 is movably mounted inside the front mold 5 , and the front mold 5 and the fixed groove 21 are fixedly connected.

[0043] When the cooling operation is completed, the staff opens the front mold 5 and the rear mold 6. If the plastic product is adhered to the front mold 5, the baffle 22 can be pressed down to allow the baffle 22 to enter the interior of the fixing groove 21. At this time, the spring 24 is compressed, and the ejector pin 23 is squeezed into the interior of the front mold 5 by the baffle 22, forcing the plastic product to separate from the front mold 5. When the product is separated, the staff releases the baffle 22. At this time, the characteristics of the baffle 22 itself cause the baffle 22 and the ejector pin 23 to reset, completing the extrusion operation of the product.

[0044] Through the extrusion of the baffle 22, the ejector pin 23 is extended into the interior of the front mold 5 to complete the demoulding operation, and then the elastic potential energy of the spring 24 is used to reset the ejector pin 23 after the demoulding is completed. Compared with the traditional device, the device makes it easier to take out and collect the plastic products inside the front mold 5 through the operation of the extrusion mechanism, thereby improving the work efficiency of the staff and reducing the workload.

[0045] The film molding mechanism includes a cooling box 7 movably mounted on the outer wall of the moving rod 4 , the cooling box 7 is fixedly connected to the rear mold 6 , the rear mold 6 is movably connected to the front mold 5 , and the cooling box 7 is fixedly connected to the outer shell 15 .

[0046] PE material is filled into the interior of the injection molding machine 2, and the front mold 5 and the rear mold 6 are closed. At this time, the injection molding machine 2 injects the melted material into the interior of the front mold 5 and the rear mold 6, and then the staff moves the front mold 5 and the rear mold 6 to the bottom of the blow molder 3, so that the blow molder 3 starts the blow molding operation.

[0047] Among them, the heat dissipation mechanism includes a heat dissipation box 8 fixedly installed on the top of the cooling box 7, a filter plate 9 is fixedly installed on the top of the heat dissipation box 8, a fixed platform 11 is fixedly installed below the filter plate 9, one end of the fixed platform 11 is fixedly connected to a motor 10, and a fan blade 12 is rotatably installed on the other end of the fixed platform 11, and the output shaft of the motor 10 passes through the fixed platform 11 and is fixedly connected to the fan blade 12.

[0048] The staff can start the motor 10 , and the operation of the motor 10 drives the fan blades 12 to rotate. The fan blades 12 filter the external air through the filter plate 9 and then blow it into the interior of the cooling box 7 through the guide hole 14 .

[0049] Among them, the ventilation mechanism includes a vent hole 13 fixedly installed inside the cooling box 7, and a guide hole 14 is rotatably installed inside the vent hole 13. One end of the guide hole 14 passes through the inside of the shell 15 and is fixedly connected to the gear 20. The gear 20 and the transmission rod 19 are meshed with each other.

[0050] Since the transmission rod 19 and the gear 20 are meshed with each other, when the motor 2 16 is started, the guide hole 14 starts to swing left and right, which assists in cooling the coolant inside the cooling box 7, thereby improving the cooling efficiency.

[0051] Water pipes 25 are fixedly installed on both sides of the cooling box 7 , there are two groups of water pipes 25 , and the cooling box 7 and the rear mold 6 are connected to each other through the water pipes 25 .

[0052] The water pipe 25 connects the cooling box 7 and the rear mold 6 to each other for circulating water cooling.

[0053] A spring 24 is fixedly disposed on the inner side of the baffle plate 22 , and the baffle plate 22 and the outer wall of the front mold 5 are elastically connected via the spring 24 .

[0054] When the product is released, the staff releases the baffle 22, at which time the baffle 22 and the ejector pin 23 are reset due to the characteristics of the baffle 22, thus completing the extrusion operation of the product.

[0055] The working principle and use process of this utility model:

[0056] When blow molding is required, the staff first ensures that there is enough coolant stored in the cooling box 7 and that the water valve of the water pipe 25 operates normally to circulate the coolant. Then, the PE material is filled into the injection molding machine 2 and the front mold 5 and the rear mold 6 are closed. At this time, the injection molding machine 2 injects the melted material into the front mold 5 and the rear mold 6. Then, the staff moves the front mold 5 and the rear mold 6 to the bottom of the blow molding machine 3 to start the blow molding machine 3. Then, the staff can start the motor 10 and the motor 2 16. The operation of the motor 10 is started. The fan blades 12 are driven to rotate. The fan blades 12 filter the outside air through the filter plate 9, and then blow it into the interior of the cooling box 7 through the guide hole 14 to cool the coolant inside. Then, the operation of the motor 16 drives the driving block 17 to rotate. The rotation of the driving block 17 drives the transmission rod 19 to move. At this time, the transmission rod 19 is restricted by the two groups of fixed blocks 18, so that it moves left and right, and the transmission rod 19 and the gear 20 are engaged with each other, causing the guide hole 14 to start swinging left and right, which assists in cooling the coolant inside the cooling box 7, thereby improving the cooling efficiency.

[0057] When the cooling operation is completed, the staff opens the front mold 5 and the rear mold 6. If the plastic product is adhered to the front mold 5, the baffle 22 can be pressed down to allow the baffle 22 to enter the interior of the fixing groove 21. At this time, the spring 24 is compressed, and the ejector pin 23 is squeezed into the interior of the front mold 5 by the baffle 22, forcing the plastic product to separate from the front mold 5. When the product is separated, the staff releases the baffle 22. At this time, the characteristics of the baffle 22 itself cause the baffle 22 and the ejector pin 23 to reset, completing the extrusion operation of the product.
