Description

Technical Field

[0001] This utility model relates to the field of extruder technology, specifically to a raw material extruder for plastic granulation. Background Technology

[0002] With the booming development of the plastic products industry, the demand for plastic raw materials is increasing day by day. Plastic granulation is one of the important links in plastic processing. As a key piece of equipment for plastic granulation, the performance and structure of the raw material extruder have a crucial impact on production efficiency and product quality. Currently, existing raw material extruders for plastic granulation usually adopt an extrusion plate structure to perform material extrusion operations. The extrusion plate is one of the core components of the extruder. However, traditional extrusion plate structures are mostly designed in a relatively fixed form, which has certain limitations in practical applications.

[0003] In existing technologies, during the use of traditional raw material extruders, material tends to remain on the extrusion plate. Over time, these residues accumulate, negatively impacting the normal operation of the extruder and product quality. However, due to the relatively fixed structure of the extrusion plate, cleaning is often difficult and requires a significant amount of time and effort, which not only increases maintenance costs but also reduces the efficiency of the equipment.

[0004] Therefore, a new type of raw material extruder for plastic granulation is needed to solve the problem that the existing raw material extruders have a relatively fixed structure of the extrusion plate, which is inconvenient for operators to clean and thus affects their performance. Utility Model Content

[0005] The purpose of this invention is to provide a raw material extruder for plastic granulation to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a raw material extruder for plastic granulation, comprising an extruder body, a hot melt cylinder and an extrusion plate, wherein an installation groove is provided on the left side of the hot melt cylinder, a support frame is inserted into the inner wall of the installation groove, connecting plates are installed on the front and rear sides of the upper part of the support frame, and positioning grooves are provided on the front and rear sides of the top of the installation groove.

[0007] Preferably, a threaded rod is threadedly connected to the middle of the support frame, and a movable groove is provided on both the front and rear sides of the upper part of the support frame. A limiting plate is installed on the inner wall of the movable groove. An insert plate is installed on one side of the limiting plate and an elastic element is installed on the other side. A connecting rope is installed on the adjacent side of the limiting plate on both the front and rear sides. A slot is provided on both the front and rear sides of the upper part of the mounting groove.

[0008] Preferably, the adjacent sides of the elastic elements on both the front and rear sides are installed on the inner wall of the moving groove, the adjacent ends of the connecting ropes on both the front and rear sides are installed between the threaded rods, the opposite sides of the insert plates on both the front and rear sides pass through the support frame and are inserted into the inner wall of the slot, and the threaded rod passes through the top of the support frame.

[0009] Preferably, an auxiliary groove is provided on the lower inner side of the support frame, and sliding grooves are provided on both the front and rear sides of the auxiliary groove. A clamping plate is installed at the bottom end of the threaded rod, and sliders are installed on both the front and rear sides of the top of the clamping plate. Elastic inserts are installed on both the front and rear sides of the extrusion plate, and two insertion slots are provided at the lower part of the support frame.

[0010] Preferably, the elastic plug is inserted into the inner wall of the insertion groove, and the opposite sides of the sliders on both the front and rear sides are slidably connected to the inner wall of the groove.

[0011] Preferably, the clamping plate is slidably connected to the inner wall of the auxiliary groove, and the bottom of the clamping plate is in contact with the top of the extrusion plate.

[0012] Preferably, the connecting plate is inserted into the inner wall of the positioning groove, and the extrusion plate is inserted into the lower part of the support frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The plastic granulation raw material extruder proposed in this utility model, by rotating the threaded rod, causes the connecting ropes on both sides to wrap around the outside of the threaded rod and move upward as the threaded rod rotates. The connecting ropes pull the limiting plates on the front and rear sides to move towards each other. While extruding the elastic element, the insert plate is driven to disengage from the slot, and then the support frame can be taken out upward, which facilitates the operator to clean the extrusion plate and improves cleaning efficiency. When resetting, after the support frame is fitted with the mounting slot, the threaded rod is reversed, and the elastic force of the elastic element pushes the insert plate to maintain the insertion with the slot, thereby improving the maintenance efficiency of the operator and also improving the use effect of the raw material extruder.

[0025] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] Example 1: Please refer to Figures 1-8 This utility model provides a technical solution: a raw material extruder for plastic granulation, including an extruder body 1, a hot melt cylinder 2, and an extrusion plate 4. An installation groove 7 is provided on the left side of the hot melt cylinder 2. A support frame 3 is inserted into the inner wall of the installation groove 7. Connecting plates 6 are installed on the front and rear sides of the upper part of the support frame 3. Positioning grooves 9 are provided on the front and rear sides of the top of the installation groove 7. The connecting plates 6 are inserted into the inner wall of the positioning grooves 9, thereby facilitating the installation of the support frame 3. The extrusion plate 4 is inserted into the lower part of the support frame 3, thereby facilitating the removal of the support frame 3 and cleaning of the extrusion plate 4, thereby improving the cleaning efficiency of the operator.

[0027] First, pull the support frame 3 upwards and slide it along the inner wall of the mounting groove 7, thereby causing the connecting plate 6 to disengage from the positioning groove 9, making it easier for the operator to clean the extrusion plate 4. After cleaning, reset the support frame 3 and insert it into the inner wall of the mounting groove 7, while simultaneously causing the connecting plate 6 to insert into the inner wall of the positioning groove 9, so as to lock the support frame 3 and the hot melt cylinder 2 together, and facilitate subsequent cleaning and use, thereby improving the performance of the extruder body 1. Example 2: Based on Example 1, in order to lock the support frame 3 and the hot melt cylinder 2 together, a threaded rod 15 is threadedly connected to the middle of the support frame 3. The upper front and rear sides of the support frame 3 are provided with moving grooves 14. The inner wall of the moving groove 14 is installed with a limiting plate 13. A plate 5 is installed on one side of the limiting plate 13, and an elastic element 16 is installed on the other side. Connecting ropes 17 are installed on the adjacent sides of the limiting plates 13 on both the front and rear sides. The upper front and rear sides of the mounting groove 7 are provided with locking grooves 8. The adjacent sides of the elastic elements 16 on both the front and rear sides are installed on the inner wall of the moving groove 14. The elastic force of the elastic element 16 is used to reset the limit plates 13 on both sides, while pushing the insert plate 5 into the inner wall of the slot 8 so as to fit the support frame 3 with the hot melt cylinder 2. The near ends of the connecting ropes 17 on the front and rear sides are installed between the threaded rods 15. The opposite sides of the insert plates 5 on the front and rear sides pass through the support frame 3 and are inserted into the inner wall of the slot 8. The threaded rod 15 passes through the top of the support frame 3. By rotating the threaded rod 15, the connecting ropes 17 on both sides are wound around its outer side and pulled upward, thereby causing the two insert plates 5 to disengage from the slot 8 so as to pull the support frame 3 upward.

[0028] First, rotate the threaded rod 15, causing the connecting ropes 17 on both sides to wrap around its outer side and move upward with the threaded rod 15. This pulls the limiting plate 13 to slide on the inner wall of the moving groove 14, and at the same time, causes one side of the insert plate 5 to disengage from the slot 8, while squeezing the elastic element 16. Then, pull the threaded rod 15 upward to drive the support frame 3 to slide upward along the inner wall of the mounting groove 7, thereby causing the connecting plate 6 to disengage from the positioning groove 9. This makes it easier for the operator to clean the extrusion plate 4. After cleaning, reset the support frame 3 and insert it into the inner wall of the mounting groove 7. At the same time, reverse the threaded rod 15, thereby using the elastic force of the elastic element 16 to push the limiting plate 13 to reset and pull the connecting rope 17 to reset. This causes the insert plate 5 to insert into the inner wall of the slot 8, so as to lock the support frame 3 and the hot melt cylinder 2 together.

[0029] Example 3: Based on Example 2, to facilitate the replacement of the extrusion plate 4, an auxiliary groove 18 is provided on the lower inner side of the support frame 3. Sliding grooves 12 are provided on both the front and rear sides of the auxiliary groove 18. A clamping plate 19 is installed at the bottom end of the threaded rod 15. Slider blocks 11 are installed on both the front and rear sides of the top of the clamping plate 19. Elastic inserts 10 are installed on both the front and rear sides of the extrusion plate 4. Two insertion slots 20 are provided at the lower part of the support frame 3. The elastic inserts 10 are inserted into the inner wall of the insertion slots 20, thereby pushing the extrusion plate 4 to the right and causing the elastic inserts 10 to disengage from the inner wall of the insertion slots 20, so as to... The extrusion plate 4 is removed. Since the elastic insert 10 is elastic, it increases the stability of the connection between the extrusion plate 4 and the support frame 3. The opposite sides of the front and rear sliders 11 are slidably connected to the inner wall of the slide groove 12. Thus, while rotating the threaded rod 15, the clamping plate 19 is driven to disengage from the top of the extrusion plate 4 so that it can be taken out. The clamping plate 19 is slidably connected to the inner wall of the auxiliary groove 18, and the bottom of the clamping plate 19 is in contact with the top of the extrusion plate 4. Thus, the clamping plate 19 is used to push the extrusion plate 4 downward, thereby making the connection between the extrusion plate 4 and the support frame 3 more stable and facilitating subsequent disassembly.

[0030] When it is necessary to replace the extrusion plate 4, rotate the threaded rod 15 to drive the front and rear side insert plates 5 to disengage from the slot 8, while simultaneously driving the clamping plate 19 to slide upward along the inner wall of the auxiliary groove 18, and driving the two sliders 11 to slide upward along the inner wall of the slide groove 12. At this time, the restriction on the extrusion plate 4 is released, and then the support frame 3 is taken out upward. The extrusion plate 4 can then be pushed to the right to drive the elastic inserts 10 on both sides to slide to the right along the inner wall of the insertion groove 20 and disengage from the support frame 3. At this time, the extrusion plate 4 can be replaced. After completion, the replaced extrusion plate 4 is inserted between the inner wall of the insertion groove 20 and the support frame 3 using the elastic inserts 10. At the same time, the support frame 3 is reset downward, and the threaded rod 15 is reversed, so that the clamping plate 19 continues to push the top of the extrusion plate 4 downward to increase the stability of the extrusion plate 4 installation and facilitate subsequent disassembly and replacement.

[0031] In actual use, first rotate the threaded rod 15, which drives the connecting ropes 17 on both sides to wrap around its outer side and move upward with the threaded rod 15. This pulls the limiting plate 13 to slide on the inner wall of the moving groove 14, and drives one side of the insert plate 5 to disengage from the slot 8. At the same time, it pushes the elastic element 16, and then pulls the threaded rod 15 upward to drive the support frame 3 to slide upward along the inner wall of the mounting groove 7. This drives the connecting plate 6 to disengage from the positioning groove 9, which makes it easier for the operator to clean the extrusion plate 4. After cleaning, the support frame 3 is reset and inserted into the inner wall of the mounting groove 7. At the same time, the threaded rod 15 is reversed, so that the elastic force of the elastic element 16 pushes the limiting plate 13 to reset and pulls the connecting rope 17 to reset. This drives the insert plate 5 to insert into the inner wall of the slot 8 to lock the support frame 3 and the hot melt cylinder 2 together, which facilitates subsequent cleaning and use, thereby improving the performance of the extruder body 1.

[0032] When it is necessary to replace the extrusion plate 4, rotate the threaded rod 15 to drive the front and rear side insert plates 5 to disengage from the slot 8, while simultaneously driving the clamping plate 19 to slide upward along the inner wall of the auxiliary groove 18, and driving the two sliders 11 to slide upward along the inner wall of the slide groove 12. At this time, the restriction on the extrusion plate 4 is released, and then the support frame 3 is taken out upward. The extrusion plate 4 can then be pushed to the right to drive the elastic inserts 10 on both sides to slide to the right along the inner wall of the insertion groove 20 and disengage from the support frame 3. At this time, the extrusion plate 4 can be replaced. After completion, the replaced extrusion plate 4 is inserted between the inner wall of the insertion groove 20 and the support frame 3 using the elastic inserts 10. At the same time, the support frame 3 is reset downward, and the threaded rod 15 is reversed, so that the clamping plate 19 continues to push the top of the extrusion plate 4 downward to increase the stability of the extrusion plate 4 installation and facilitate subsequent disassembly and replacement.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
