Description

Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to a movable plastic particle drying bin. Background Art

[0002] In the injection molding process, preheating of raw material pellets is a key step. Through preheating, the raw material pellets can reach a suitable temperature before entering the injection molding machine, so that they can melt more quickly during formal processing. Doing so can not only improve the fluidity of the raw materials, but also reduce processing time and improve production efficiency.

[0003] However, in actual operation, the preheating process often faces some challenges. Different injection molding equipment may have different steps when loading and discharging raw materials, which makes it difficult to achieve fast loading or discharging of common raw materials. Therefore, a movable plastic granule drying bin is proposed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a movable plastic particle drying bin, which has the advantages of rapid transfer and switching of common materials between different models, saving switching time, reducing the time and labor cost waste of loading and unloading time during switching, and improving machine utilization efficiency, and solves the problem that different injection molding equipment may have different steps when performing raw material loading and discharging operations, which makes it difficult to achieve rapid loading or discharging of common raw materials during pretreatment.

[0005] To achieve the above object, the utility model provides the following technical solutions: a movable plastic particle drying bin, comprising a bottom plate, a drying barrel is fixedly installed on the rear end of the upper surface of the bottom plate, a control mechanism is fixedly installed on one side of the front end of the upper surface of the bottom plate, and also includes an air injection pipe;

[0006] The air injection pipe is movably inserted at the bottom of the drying barrel;

[0007] Wherein, the gas injection pipe is movably mounted on the upper surface of the base plate through a longitudinal electric telescopic rod;

[0008] Wherein, the longitudinal electric telescopic rod is slidably mounted on the bottom plate via the transverse electric telescopic rod;

[0009] The end of the air injection pipe away from the drying barrel is connected and installed with the exhaust end of the control mechanism through a connecting hose.

[0010] When using a movable plastic particle drying bin in the technical solution, by turning on the fan in the control mechanism and closing the end of the connecting hose away from the control mechanism through the control valve, negative pressure is formed in the drying barrel. After the negative pressure is formed in the drying barrel, the feed pipe is opened and the plastic particle raw material is sucked into the drying barrel by the negative pressure. At this time, the temperature controller and the fan can be turned on at the same time, and the connecting hose is connected to the air injection pipe, so that hot air is injected into the drying barrel through the air injection pipe. The plastic particles are evenly heated and dried in the drying barrel, and the formed hot air circulates in the drying barrel until the plastic particles reach the required degree of dryness. After the drying is completed, the temperature controller and the fan are stopped by the control mechanism, and the air release pipe is opened by the control valve, so as to gradually evacuate the residual hot air in the air injection pipe. The air injection pipe is pulled out and removed from the bottom of the drying barrel by the longitudinal electric telescopic rod and the transverse electric telescopic rod, so as to achieve separation from the drying barrel. At this time, the dried plastic particles are discharged from the bottom of the drying barrel and fall into the material guide trough, thereby completing the entire drying and discharging process.

[0011] Preferably, a reserved groove is provided in the middle front end of the upper surface of the base plate, a guide frame is fixedly installed on the lower surface of the base plate at the bottom of the reserved groove, the bottom end of the longitudinal electric telescopic rod is slidably installed on the inner side of the guide frame, a push-pull frame is fixedly installed on the front end of the upper surface of the base plate, and universal wheels are fixedly installed at the four corners of the lower surface of the base plate.

[0012] This design enables the longitudinal electric telescopic rod to slide stably in the guide frame, ensuring precise control and stability of the gas injection pipe when inserting and withdrawing it from the drying drum, which helps to improve the reliability and safety of operation.

[0013] Preferably, a cover body is threadedly mounted on the top of the drying barrel, and the bottom of the drying barrel is fixedly connected to the rear end of the upper surface of the base plate through a support frame.

[0014] This threaded connection ensures the sealing between the cover and the drying barrel. At the same time, the fixed connection between the support frame and the bottom plate provides a firm support for the drying barrel, ensuring stability during the drying process.

[0015] Preferably, holes are opened on both sides of the upper surface of the cover body and a feed pipe and an exhaust pipe are installed in connection therewith. A connecting pipe is movably mounted on the exhaust pipe. The end of the connecting pipe facing away from the exhaust pipe is connected to the air inlet end of the control mechanism. A filter pocket is fixedly installed on the inner side of the cover body below the exhaust pipe.

[0016] This design allows the raw materials to enter the drying barrel through the feed pipe and discharge the moisture and heat generated during drying through the exhaust pipe. The connection between the connecting pipe and the control mechanism ensures the recycling of the hot air, while the filter bag prevents the discharge of plastic particles during the drying process.

[0017] Preferably, a material guide trough is fixedly installed at the inner bottom of the support frame, and the front end of the material guide trough is fixedly connected to an end of the transverse electric telescopic rod away from the longitudinal electric telescopic rod.

[0018] The design of the material guide chute allows the dried plastic particles to be discharged smoothly from the drying barrel, while the connection with the horizontal electric telescopic rod improves the stability of the horizontal electric telescopic rod after installation.

[0019] Preferably, a control valve is fixedly installed at one end of the air injection pipe away from the drying barrel. The control valve adopts a three-way valve structure design. The end of the control valve away from the air injection pipe is connected to a connecting hose, and a venting pipe is connected to the control valve.

[0020] The design of the three-way valve structure enables the control valve to flexibly control the flow direction of hot air, and the vent pipe can be used to discharge excess hot air to ensure the normal operation of the system.

[0021] Preferably, the control mechanism comprises a temperature controller and a fan, the temperature controller is arranged at the air inlet end of the control mechanism, and the fan is arranged at the air outlet end of the control mechanism.

[0022] This design enables the control mechanism to accurately control the temperature and wind speed during the drying process, ensuring that the plastic particles achieve the ideal drying effect during the drying process. The coordinated work of the temperature controller and the fan improves the automation and efficiency of the entire drying process.

[0023] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0024] The utility model provides an air injection pipe, and the air injection pipe is movably installed above the bottom plate through a longitudinal electric telescopic rod and a transverse electric telescopic rod. This design allows the air injection pipe to flexibly approach or move away from the drying barrel. The end of the air injection pipe away from the drying barrel is connected and installed with the exhaust end of the control mechanism through a connecting hose. This design makes the drying process more automated through the control mechanism, reduces manual intervention, and improves the utilization efficiency of the machine. Universal wheels are fixedly installed at the four corners of the lower surface of the bottom plate, respectively, so that the entire drying bin can be easily moved to different injection molding equipment. This mobility design not only facilitates the transfer of equipment, but also makes the pretreatment of raw materials more convenient. Flexible and adaptable to different production needs, through the cooperation of the longitudinal electric telescopic rod and the transverse electric telescopic rod, the air injection pipe can be quickly pulled out from the bottom of the drying barrel to achieve rapid discharge. This design reduces the time of discharge operation and improves production efficiency. The design of the entire drying bin takes into account the operation requirements of different injection molding equipment. Through standardized interfaces and modular design, the equipment can adapt to a variety of machine models, solve the problem of inconsistent operating steps between different equipment, and achieve the rapid transfer and switching of common materials between different models, saving switching time, reducing the time and labor cost waste of loading and unloading time during switching, and improving the utilization efficiency of the machine.

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] Example

[0033] like Figures 1 to 5 As shown, an embodiment provided by the utility model: a movable plastic particle drying bin, comprising a bottom plate 1, a drying barrel 3 is fixedly installed on the rear end of the upper surface of the bottom plate 1, a control mechanism 10 is fixedly installed on one side of the front end of the upper surface of the bottom plate 1, and also includes an air injection pipe 2;

[0034] Specifically, by setting the injection pipe 2 and making the injection pipe 2 movably installed above the bottom plate 1 through the longitudinal electric telescopic rod 13 and the transverse electric telescopic rod 14, this design enables the injection pipe 2 to approach or move away from the drying barrel 3 flexibly. One end of the injection pipe 2 facing away from the drying barrel 3 is connected and installed with the exhaust end of the control mechanism 10 through a connecting hose 18. This design makes the drying process more automated through the control mechanism 10, reduces manual intervention, and improves the utilization efficiency of the machine. Universal wheels 11 are respectively fixedly installed at the four corners of the lower surface of the bottom plate 1, enabling the entire drying bin to be easily moved beside different injection molding devices. This mobility design not only facilitates the transfer of the equipment but also makes the pretreatment of raw materials more flexible to adapt to different production requirements. Through the cooperation of the longitudinal electric telescopic rod 13 and the transverse electric telescopic rod 14, the injection pipe 2 can be quickly withdrawn from the bottom of the drying barrel 3 to achieve rapid discharging. This design reduces the time of discharging operation and improves production efficiency. The design of the entire drying bin takes into account the operation requirements of different injection molding devices. Through standardized interfaces and modular design, the equipment can adapt to multiple models, solves the problem of inconsistent operation steps between different devices, achieves the rapid transfer, switching of common materials between different models, saves switching time, reduces the waste of labor costs for loading and unloading back and forth during switching, and improves the utilization efficiency of the machine.

[0035] Further, a reserved groove 16 is opened at the front end of the middle part of the upper surface of the bottom plate 1. A guiding frame 15 is fixedly installed on the lower surface of the bottom plate 1 at the bottom of the reserved groove 16. The bottom end of the longitudinal electric telescopic rod 13 is slidably installed inside the guiding frame 15. A push-pull frame 12 is fixedly installed at the front end of the upper surface of the bottom plate 1. Universal wheels 11 are respectively fixedly installed at the four corners of the lower surface of the bottom plate 1.

[0036] This design enables the longitudinal electric telescopic rod 13 to stably slide inside the guiding frame 15, ensuring the precise control and stability of the injection pipe 2 when inserting into and withdrawing from the drying barrel 3, which helps to improve the reliability and safety of the operation.

[0037] Further, a cover body 4 is installed on the top of the drying barrel 3 by threading. The bottom of the drying barrel 3 is fixedly connected to the rear end of the upper surface of the bottom plate 1 through a support frame 8.

[0038] This threaded connection method ensures the sealing between the cover body 4 and the drying barrel 3. At the same time, the fixed connection between the support frame 8 and the bottom plate 1 provides a stable support for the drying barrel 3, ensuring stability during the drying process.

[0039] Further, feeding pipes 5 and exhaust pipes 6 are respectively opened and connected and installed on both sides of the upper surface of the cover body 4. A connecting pipe 7 is movably sleeved on the exhaust pipe 6. One end of the connecting pipe 7 facing away from the exhaust pipe 6 is connected and installed with the intake end of the control mechanism 10. A filter pocket 17 is fixedly installed inside the cover body 4 below the exhaust pipe 6.

[0040] This design allows the raw materials to enter the drying barrel 3 through the feed pipe 5, and discharge the moisture and hot air generated during drying through the exhaust pipe 6. The connection of the connecting pipe 7 to the control mechanism 10 ensures the recyclability of the hot air, while the filter pocket 17 prevents the plastic particles from discharging during the drying process.

[0041] Furthermore, a material guiding groove 9 is fixedly installed at the inner bottom of the support frame 8, and the front end of the material guiding groove 9 is fixedly connected to the end of the transverse electric telescopic rod 14 away from the longitudinal electric telescopic rod 13.

[0042] The design of the material guiding groove 9 enables the dried plastic particles to smoothly discharge from the drying barrel 3, and the connection with the transverse electric telescopic rod 14 improves the stability of the transverse electric telescopic rod 14 after installation.

[0043] Furthermore, a control valve 20 is fixedly installed at the end of the gas injection pipe 2 away from the drying barrel 3. The control valve 20 adopts a three-way valve structure design. The end of the control valve 20 away from the gas injection pipe 2 is connected and installed with a connecting hose 18, and an air release pipe 19 is connected and installed on the control valve 20.

[0044] The design of the three-way valve structure enables the control valve 20 to flexibly control the flow direction of the hot air, and the air release pipe 19 can be used to discharge the excess hot air to ensure the normal operation of the system.

[0045] Furthermore, the control mechanism 10 includes a temperature controller and a blower. The temperature controller is arranged at the air inlet end of the control mechanism 10, and the blower is arranged at the air outlet end of the control mechanism 10.

[0046] This design enables the control mechanism 10 to accurately control the temperature and wind speed during the drying process, ensuring that the plastic particles achieve an ideal drying effect during the drying process. The coordinated work of the temperature controller and the blower improves the automation degree and efficiency of the entire drying process.

[0047] When the utility model is in use, the fan in the control mechanism 10 is turned on, and the end of the connecting hose 18 away from the control mechanism 10 is closed through the control valve 20, so as to form a negative pressure in the drying barrel 3. After the negative pressure is formed in the drying barrel 3, the feed pipe 5 is opened, and plastic particle raw materials are sucked into the drying barrel 3 by using the negative pressure. At this time, the temperature controller and the fan can be turned on simultaneously, and the connecting hose 18 is connected to the injection pipe 2, so as to inject hot air into the drying barrel 3 through the injection pipe 2. The plastic particles are evenly heated and dried in the drying barrel 3, and the formed hot air circulates in the drying barrel 3 until the plastic particles reach the required drying degree. After the drying is completed, the temperature controller and the fan are stopped through the control mechanism 10, and the air release pipe 19 is opened through the control valve 20, so as to gradually empty the residual hot air in the injection pipe 2. The injection pipe 2 is pulled out from the bottom of the drying barrel 3 and moved away by using the longitudinal electric telescopic rod 13 and the transverse electric telescopic rod 14, so as to realize the separation from the drying barrel 3. At this time, the dried plastic particles are discharged from the bottom of the drying barrel 3 and fall into the material guiding groove 9, thus completing the whole drying and discharging process.
