[0002] A preform injection molding machine is a type of machinery specifically designed for producing plastic preforms. Preforms are a key intermediate product in the plastic bottle manufacturing process. After being processed and shaped by the injection molding machine, they undergo blow molding to become the final plastic bottle. The main function of the preform injection molding machine is to heat and plasticize the plastic raw material and inject it into the mold cavity under high pressure. After cooling and solidification, the preform is formed. When using a preform injection molding machine, a barrel structure is often used; however, existing injection molding machine barrel structures still present some problems in actual use. For example, application number CN201822275637.8 discloses a barrel structure for an injection molding machine, including an injection barrel, an injection nozzle, auxiliary stirring teeth, a heat insulation shell, a vacuum chamber, a heat insulation layer, a ceramic filler block, an electric heating wire, a pump connecting pipe, a feed pipe, a guide fixing block, a sleeve rod, an adjusting rod, a positioning arc plate, a locking screw, and a telescopic rod. It has the characteristics of facilitating the disassembly and installation of the screw without affecting the normal use of the injection molding machine. Existing injection molding machine barrel structures often directly convey the injection molding raw materials during use, which may cause blockage inside the barrel during the transmission process, thus affecting the working effect.

[0003] To address the aforementioned issues, a multi-stage temperature-controlled barrel structure for preform injection molding machines is proposed. Utility Model Content

[0008] Preferably, the baffle is slidably connected inside the hopper, and a transmission gear is fixedly connected to one side of the crushing roller.

[0009] The design of the above structure, through the sliding connection of the baffles, ensures that the baffles will not deviate from their movement trajectory during the movement process.

[0010] Preferably, the two sets of transmission gears are meshed with each other, a motor is fixedly connected inside the processing chamber, the motor has a heat dissipation vent for power supply heat dissipation, and a bevel gear is fixedly connected to the output end of the motor.

[0016] Preferably, the connecting block is fixedly connected to the screw conveyor rod, and an electric heating tube is fixedly connected inside the conveying pipe, with multiple sets of the electric heating tube provided.

[0017] The above-described structure, with the addition of an electric heating element, enables workers to easily control the temperature of the material conveying pipe.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This application achieves the function of pre-processing raw materials before feeding by setting up a motor, bevel gear, transmission gear and baffle, which improves the subsequent use effect and solves the problem that the existing injection molding machine barrel structure often directly feeds the injection molding raw materials, which may cause blockage inside the barrel during the transmission process, thus affecting the working effect. 2.

[0023] Combination Figures 1-4The barrel structure of the multi-stage temperature-controlled preform injection molding machine includes a processing chamber 1 and a temporary storage chamber 11 fixedly connected above the processing chamber 1. The top of the temporary storage chamber 11 is provided with a placement opening. The processing chamber 1 is provided with a processing mechanism, which performs the function of processing raw materials. The processing mechanism includes a crushing chamber 12 fixedly connected to the bottom of the temporary storage chamber 11. A storage chamber 111 is fixedly connected inside the temporary storage chamber 11. A crushing roller 121 is rotatably connected inside the crushing chamber 12, and two sets of crushing rollers 121 are provided.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] Example 1: To address the problem that existing injection molding machine barrel structures often directly convey injection molding materials, which can lead to internal blockages during transport and thus affect work efficiency, this embodiment discloses the following technical solution, specifically as follows: Figures 1-5As shown, an electric push rod 112 is fixedly connected to one side of the temporary storage chamber 11, and a baffle 113 is fixedly connected to the output end of the electric push rod 112. A hopper 114 is fixedly connected to the bottom of the receiving chamber 111, and the baffle 113 is slidably connected inside the hopper 114. A transmission gear 122 is fixedly connected to one side of the crushing roller 121, and two sets of transmission gears 122 are meshed with each other. A motor 13 is fixedly connected inside the processing chamber 1, and the motor 13 has a heat dissipation vent for heat dissipation. A bevel gear 131 is fixedly connected to the output end of the motor 13. Two sets of bevel gears 131 are provided, and a bevel gear 132 is meshed with one side of the bevel gear 131. One set of bevel gears 132 is fixedly connected to the transmission gear 122. A conveying pipe 14 is fixedly connected to one side of the processing chamber 1, and a screw conveyor 141 is fixedly connected to one side of the other set of bevel gears 132. When When using the device, the injection molding material can be placed inside the storage opening of the temporary storage chamber 11. After the material enters the storage chamber 111, the operator can activate the electric push rod 112. The electric push rod 112 drives the baffle 113 to move, which in turn moves the baffle 113 inside the feeding hopper 114. At this time, the material will enter the crushing chamber 12 through the feeding hopper 114. Then, the operator can activate the motor 13. The motor 13 drives the two sets of bevel gears 131 to rotate. The bevel gears 131 drive the bevel gears 132 to rotate, which in turn drives the transmission gears 122. The transmission gears 122 of one set drive the transmission gears 122 of the other set to rotate. The rotation of the two sets of transmission gears 122 causes the two sets of crushing rollers 121 to rotate, thereby crushing the material and preventing subsequent blockage. The other set of bevel gears 131 and bevel gears 132... With the help of the drive screw conveyor 141 to rotate, the screw conveyor 141 rotates inside the conveying pipe 14, thereby conveying the raw materials. This enables the pre-processing of the raw materials before conveying, improving the subsequent use effect.

[0026] Example 2: To address the problems of existing injection molding machine barrels having limited functionality, hindering temperature control, and making it difficult to improve plasticization uniformity when dealing with different plastics, thus affecting the machine's efficiency, this embodiment discloses the following technical solution, specifically as follows: Figure 6As shown, the screw conveyor 141 is rotatably connected to the inside of the conveying pipe 14. A connecting block 142 is fixedly connected inside the conveying pipe 14, and the connecting block 142 is fixedly connected to the screw conveyor 141. An electric heating tube 143 is fixedly connected inside the conveying pipe 14. Multiple sets of electric heating tubes 143 are provided. When in use, the operator can activate the electric heating tubes 143 located inside the conveying pipe 14. The multiple sets of electric heating tubes 143 can heat the inside of the conveying pipe 14. When the operator needs to control the temperature of the conveying pipe 14, the corresponding electric heating tube 143 can be activated, thereby achieving multi-stage temperature control of the conveying pipe 14. This is suitable for different plastic requirements and enables the operator to conveniently control the temperature of the conveying pipe 14, improving work efficiency.
