Description

Technical Field

[0001] This utility model relates to the field of plastic steel profile production technology, specifically a novel feeding structure for an extruder used in plastic steel profile production. Background Technology

[0002] Plastic steel profiles, also known as PVC profiles, are primarily composed of PVC. They are a widely used new type of building material. Due to their excellent physical properties such as rigidity, elasticity, corrosion resistance, and aging resistance, they are commonly used in residential construction for sliding and casement doors and windows, railings, pipes, and ceiling materials. Through new processing techniques, they are also widely used in automotive engine protection panels. They are lightweight, have good toughness, and possess excellent rigidity; sometimes they are also called alloy plastic steel. The machines used to produce plastic steel profiles are called extruders. In the PVC processing, powdered PVC raw materials are fed into the equipment, mixed with other materials, melted at high temperatures, and then extruded through molds to form the corresponding PVC products.

[0003] The existing technical solution has at least the following drawbacks: Currently, PVC raw materials are typically stored in woven bags, which require tearing and emptying the bags after feeding. This method significantly impacts feeding efficiency, consequently affecting the extruder's working efficiency, and urgently needs improvement. Therefore, we propose a novel feeding structure for extruders used in the production of PVC profiles. Utility Model Content

[0004] The purpose of this utility model is to provide a new feeding structure for an extruder used in the production of plastic steel profiles, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel feeding structure for an extruder used in the production of plastic steel profiles, comprising an extruder body, a feeding channel at the upper end of the extruder body, a conveyor belt above the feeding channel, support frames fixedly installed on both sides of the extruder body, multiple support rods welded to both sides of the feeding channel, a through groove at the upper end of the support frame, a support mesh plate detachably installed in the middle of the feeding channel, a hinge seat below the support mesh plate, the hinge seat being fixedly connected to the inner wall of the feeding channel, a blade holder rotatably installed on one side of the hinge seat, a strip groove in the middle of the support mesh plate, a hydraulic cylinder fixedly installed on the other side of the feeding channel, and a vibration motor detachably installed on one side of the feeding channel.

[0006] By adopting the above technical solution, the hydraulic cylinder can drive the push rod to move to the left, which in turn pushes the cutter holder and rotates it to the left. This allows the cutter holder to squeeze and cut the woven bags that fall into the feeding channel, facilitating the discharge of the PVC raw materials stored inside. This eliminates the hassle of workers climbing to the feeding port to manually cut and dump the bags. Furthermore, the vibration motor, in conjunction with the support rod, can drive the feeding channel to vibrate slightly, causing the woven bags on the support mesh plate to vibrate and discharge. At the same time, the support mesh plate intercepts the cut woven bags, discharging the PVC raw materials stored inside into the extruder body. The remaining woven bags in the feeding channel can then be periodically cleaned out, thereby improving the feeding efficiency of the extruder.

[0007] Optionally, the size of the tool holder is adapted to the size of the slot, and the tool holder is movably connected to the slot.

[0008] By adopting the above technical solution, the design of the slot facilitates the rotation of the tool holder within the slot.

[0009] Optionally, a return spring is sleeved on the outer side of the support rod, and the other end of the return spring is fixedly connected to the outer wall of the feeding channel.

[0010] By adopting the above technical solution and setting the reset spring, the resonance effect of the feeding channel is improved, thereby ensuring the vibration discharge of PVC raw materials in the woven bag.

[0011] Optionally, the size of the support rod is adapted to the size of the through groove, and the support rod is movably connected to the through groove.

[0012] By adopting the above technical solution, the stability of the feeding channel is ensured through the cooperation of the support rod and the through groove.

[0013] Optionally, a push rod is installed at the output end of the hydraulic cylinder, and one end of the push rod passes through the other side of the feeding channel and is located below the tool holder.

[0014] By adopting the above technical solution and setting up the push rod, the tool holder can be pushed and rotated.

[0015] Optionally, the lower end of the feeding channel is connected to the upper end of the extruder body.

[0016] By adopting the above technical solution and setting up the feeding channel, it is convenient to store woven bags.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] This technical solution, through the design of the extruder body, conveyor belt, feeding channel, support mesh plate, hydraulic cylinder, push rod, and vibration motor, allows the hydraulic cylinder to drive the push rod to move to the left, which in turn pushes the cutter holder, causing it to rotate to the left. This allows the cutter holder to squeeze and puncture the woven bags falling into the feeding channel, facilitating the discharge of the PVC raw materials stored inside. This eliminates the need for workers to climb to the feeding port to manually puncture and dump the bags. Furthermore, the vibration motor, in conjunction with the support rod, causes the feeding channel to vibrate slightly, causing the woven bags on the support mesh plate to vibrate and discharge. Simultaneously, the support mesh plate intercepts the punctured woven bags, discharging the PVC raw materials inside into the extruder body. The remaining woven bags in the feeding channel are periodically cleaned out, thus improving the feeding efficiency of the extruder. Attached Figure Description

[0024] Please see Figure 1-3This utility model provides a technical solution: a novel feeding structure for an extruder used in the production of plastic steel profiles, comprising an extruder body 1, a feeding channel 12 at the upper end of the extruder body 1, a conveyor belt 11 above the feeding channel 12, support frames 13 fixedly installed on both sides of the extruder body 1, multiple support rods 3 welded to both sides of the feeding channel 12, a through groove 4 opened at the upper end of the support frame 13, a support mesh plate 2 detachably installed in the middle of the feeding channel 12, a hinge seat 21 below the support mesh plate 2, the hinge seat 21 being fixedly connected to the inner wall of the feeding channel 12, a blade holder 22 rotatably installed on one side of the hinge seat 21, and a strip groove 23 opened in the middle of the support mesh plate 2. A hydraulic cylinder 24 is fixedly installed on the other side of the feeding channel 12. A vibration motor 6 is detachably installed on one side of the feeding channel 12. The size of the support rod 3 is adapted to the size of the through groove 4, and the support rod 3 is movably connected to the through groove 4. The stability of the feeding channel 12 is ensured by the cooperation between the support rod 3 and the through groove 4. A push rod 25 is installed at the output end of the hydraulic cylinder 24. One end of the push rod 25 passes through the other side of the feeding channel 12 and is set below the knife holder 22. The knife holder 22 can be pushed and rotated by the push rod 25. The lower end of the feeding channel 12 is connected to the upper end of the extruder body 1. The feeding channel 12 facilitates the storage of woven bags.

[0025] The dimensions of the tool holder 22 are matched with the dimensions of the strip groove 23, and the tool holder 22 and the strip groove 23 are movably connected. The setting of the strip groove 23 facilitates the rotation of the tool holder 22 within the strip groove 23.

[0026] A return spring 5 is sleeved on the outer side of the support rod 3. The other end of the return spring 5 is fixedly connected to the outer wall of the feeding channel 12. By setting the return spring 5, the resonance effect of the feeding channel 12 is improved, thereby ensuring the vibration discharge of PVC raw materials in the woven bag.

[0027] During feeding, the woven bags containing PVC raw materials are conveyed to the top of the feeding channel 12 via the conveyor belt 11. After the woven bags fall into the feeding channel 12, the hydraulic cylinder 24 is opened. The hydraulic cylinder 24 drives the push rod 25 to move to the left, and the push rod 25 pushes the cutter holder 22, which in turn rotates to the left. This causes the cutter holder 22 to squeeze and cut the woven bags that have fallen into the feeding channel 12, thus facilitating the discharge of the PVC raw materials stored in the woven bags. This eliminates the trouble of workers climbing to the feeding port to manually cut and dump the woven bags. Then, the vibration motor 6 is turned on. The vibration motor 6, together with the support rod 3, drives the feeding channel 12 to vibrate slightly, which causes the woven bags on the support mesh plate 2 to vibrate and discharge. At the same time, the support mesh plate 2 intercepts the cut woven bags and discharges the PVC raw materials stored in the woven bags into the extruder body 1. The woven bags remaining in the feeding channel 12 are then cleaned out periodically, thereby improving the feeding efficiency of the extruder.
