Description

Technical Field

[0001] This utility model relates to the field of preheating equipment technology, specifically to adjustable raw material preheating equipment. Background Technology

[0002] The field of preheating equipment technology involves heating raw materials or supplies before processing to ensure they reach their optimal processing state in subsequent production processes. In PET preform production, uniform and controllable heating of the preforms ensures that they will not deform or crack during molding. Adjustable raw material preheating equipment allows for flexible adjustment of the equipment's height according to usage requirements, facilitating convenient feeding and unloading and improving production efficiency.

[0003] Chinese utility model patent CN220802751 U discloses a preheating mixing device, which includes "through the cooperation of a sealing device and a discharge control device, the sealing block can allow the opening on the surface of the discharge pipe to be exposed, so that the raw materials inside the mixing tank can be discharged through the discharge plate, and the operator can collect them. By controlling the discharge of raw materials, the device does not require the cooperation of other devices and structures, which reduces the workload of the operator and improves the practicality of the device. By controlling the sealing of the feed pipe, the probability of foreign matter entering the device and affecting the quality of the raw materials is reduced." However, in the above patent, the mixing tank is designed to be fixed, and when discharging, the material is discharged directly from the opening on the surface of the discharge pipe. At this time, it is difficult to adjust the height of the equipment according to the amount of material discharged so as to place a storage bin of corresponding capacity at the bottom of the mixing tank. This leads to additional downtime operations to replace the full storage bin, which is inconvenient to use, increases labor costs, and reduces operating efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable raw material preheating device to solve the problem mentioned in the background art of difficulty in adjusting the height of the device according to the amount of material discharged.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable raw material preheating device, including a base, wherein sliding grooves are provided at both ends of the upper surface of the base, and a material collection bin is slidably connected inside the sliding grooves.

[0006] A support frame is installed at one end of the top of the base, a servo motor is installed at the top of the support frame, a screw is driven at the bottom of the servo motor, a slider is threaded onto the surface of the screw, and a slide rod is slidably connected to one end of the slider.

[0007] A material barrel is welded to one side of the slider, and a slide block is welded to the side of the material barrel away from the slider. A slide frame is slidably connected to the surface of the slide block.

[0008] Several threaded holes are provided on one side of the slide.

[0009] A support frame is installed in the middle of one side of the sliding frame, and a pull rod is slidably connected inside the support frame. One end of the pull rod has a threaded groove.

[0010] A limit ring is installed on one end of the pull rod surface near the threaded groove, and a return spring is provided on one side of the limit ring.

[0011] The beneficial effects of this utility model are as follows: by starting the servo motor, the screw is driven to rotate, and then the power transmission of the screw thread is used to drive the material bucket to adjust its height in the vertical direction. The addition of the height adjustment design allows the operator to adjust the height of the equipment as needed so that storage bins of different capacities can be placed at the bottom of the mixing bucket. This avoids the extra operation of stopping the machine to replace the storage bins when they are full, improves the applicability and ease of operation of the equipment, avoids additional downtime, improves work efficiency, and reduces labor costs.

[0012] To allow the material to be processed to be injected into the hopper from the top, while simultaneously agitating and heating it, and to control the material to be discharged from the bottom of the hopper after processing:

[0013] The material is further configured such that: a lid is installed on the top of the material hopper, a feed hopper is installed at one end of the top of the lid, a geared motor is installed in the middle of the upper surface of the lid, a stirring rod is driven at the bottom of the geared motor, heating rods are provided at both ends of the stirring rod, a discharge hopper is installed at the bottom of the material hopper, and an electronic valve is installed at the bottom of one side of the discharge hopper.

[0014] By adopting the above technical solution, the material is gradually injected into the material barrel through the feeding hopper. Then, the external power supply is turned on, and the geared motor and heating rod are started at the same time to stir and heat the material. After the preheating operation is completed, the power supply can be turned on, the electronic valve can be started, and the material can be discharged from the bottom of the discharge hopper.

[0015] To allow the material bucket to be simultaneously moved by both the slider and the slide block, sliding along the surface of the slide rod, and thus adjusting its height in the vertical direction:

[0016] The slider is further configured such that it forms a transmission structure with a screw and a servo motor, and a groove is provided on one side of both the support frame and the slide frame. The two ends of the screw are rotatably installed on one end of the inner wall of the groove, and the two sides of the slide rod are installed on the other end of the inner wall of the groove.

[0017] By adopting the above technical solution, the servo motor is started to drive the screw to rotate inside the slide groove. Then, the screw is driven to lift or lower the slider vertically along the direction of the slide rod by using the screw thread to drive the material bucket to adjust its height in the vertical direction. At the same time, the slide block will slide and move inside the slide frame.

[0018] To enable the slide to engage with multiple threaded holes and lock the material bucket at a certain height:

[0019] The threaded holes are further configured such that they are evenly and equidistantly distributed on one side of the slide.

[0020] By adopting the above technical solution, the pull rod can be inserted into the threaded hole at any height position, thereby driving the slide to lock at multiple positions.

[0021] To ensure that the threaded groove at one end of the tie rod can be rotated and inserted into the threaded hole for a high degree of locking, and to withstand a certain amount of resistance to prevent it from falling out:

[0022] The design is further configured such that: a handle is installed on one side of the pull rod, and the pull rod forms a pull-out structure with the upright frame through the handle, and the limiting ring forms a buffer structure with the upright frame through a return spring.

[0023] By adopting the above technical solution, pulling the handle causes the pull rod to extend outward, while the return spring contracts and aligns one end of the pull rod's threaded groove with the threaded hole at the corresponding height. Then, the handle is released, and the elastic force is used to press against the opening of the threaded hole. Finally, by rotating the handle, the threaded end of the pull rod can be screwed into the threaded hole, thus locking the slide at the correct height.

[0024] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0043] The adjustable raw material preheating equipment operates as follows:

[0044] First, before preheating, pull the handle to extend the pull rod 14 outwards as needed, while the return spring 17 retracts. Then, start the servo motor 5 (model: 60E7) to rotate the screw 6 inside the slide groove 2. This, in turn, uses the threaded transmission force to lift the slider 7 vertically along the direction of the slide rod 8, thereby raising the height of the material bucket 9 vertically. Simultaneously, the slide block 10 slides and moves horizontally inside the slide frame 11. Similarly, the servo motor 5 can be reversed to lower the height of the material bucket 9 until the threaded hole 12 at the desired height is aligned with the pull rod 14. Then, release the handle and use the elastic force to press against the opening of the threaded hole 12. Simultaneously, rotate the handle to screw the threaded groove 15 end of the pull rod 14 into the thread. Inside hole 12, the height of slide 10 can be locked, thus completing the height adjustment. Then, the corresponding size of the collection bin 3 is slidably inserted into the slide groove 2. The operator can then gradually inject the material into the material bucket 9 through the feed hopper 19. After the injection is complete, the external power supply is turned on, and the geared motor 20 (model: BWFD150) and heating rod 22 (model: WB5041) are started to stir and preheat the material. After the preheating is completed, the power supply can be turned on again, and the electronic valve 24 (model: 4WE6H61) can be started to drive the material out from the bottom of the discharge hopper 23 and into the collection bin 3, thus completing the preheating operation. Finally, by pulling the handle on one side of the collection bin 3, the collection bin 3 and the preheated material can be slid out.
