Description

Technical Field

[0001] This utility model relates to the field of leak prevention technology for modified plastic granules, specifically to a leak prevention device for feeding modified plastic granules. Background Technology

[0002] In the field of modified plastic granule processing, the feeding process is a crucial step. Modified plastic granule processing machines are usually equipped with feed pipes for material conveying. However, in actual production, the feed pipe and the feeding machine are generally rigidly connected. Since the machine inevitably vibrates during operation, the rigid connection may become misaligned, potentially leading to plastic granule leakage. If a flexible connection is used, such as a clamp, the clamp may loosen due to machine vibration, causing the connection to detach, which could also result in plastic granule leakage. This leads to material waste, increased production costs, and may also affect the cleanliness of the production environment, while reducing production efficiency. Utility Model Content

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A leak-proof device for feeding modified plastic granules includes a modified plastic granule processing machine. A feed pipe is installed on the top of the modified plastic granule processing machine, and a first installation hose is sleeved on the outer ring of the feed pipe. A connecting pipe is fixedly installed at the top of the first installation hose. A receiving hopper is welded to the outer ring of the connecting pipe. A second installation hose is fixedly installed at the top of the connecting pipe. A hose clamp is provided on one side of the outer ring of both the first installation hose and the second installation hose.

[0006] The hose clamp consists of a hose clamp steel strip, a hose clamp head, and a screw. The hose clamp steel strip is attached to the outer ring of the first and second mounting hoses.

[0025] Example 1:

[0026] like Figures 1 to 3As shown, this embodiment provides a leak-proof device for feeding modified plastic granules, including a modified plastic granule processing machine 1. A feed pipe is installed on the top of the modified plastic granule processing machine 1. First, a first installation hose 2 is fitted onto the outer ring of the feed pipe of the modified plastic granule processing machine 1 to ensure a tight fit. Then, the bottom end of a connecting pipe 5 is fixedly installed to the top end of the first installation hose 2. The connection can be made by welding or other connection methods to ensure a stable connection. A receiving hopper 3 is welded to the outer ring of the connecting pipe 5. A second installation hose 4 is fixedly installed on the top end of the connecting pipe 5, also ensuring a tight connection. The second installation hose 4 is used for subsequent connection with a feeding device, such as a feeding auger. The size of the receiving hopper 3 can be designed according to actual needs, preferably to effectively receive the modified plastic granules that leak from the second installation hose 4.

[0027] At the connection points between the first installation hose 2 and the second installation hose 4 and adjacent components, hose clamps are used for tightening and sealing. The hose clamp consists of a hose clamp steel strip 6, a hose clamp head 9, and a screw 11. The hose clamp steel strip 6 is attached to the outer ring of the first installation hose 2 and the second installation hose 4. The screw 11 extends from the inside of the hose clamp head 9. A ratchet 12 is fixedly installed on the outer ring of the screw 11. An installation groove is provided on one side of the hose clamp head 9, and a pawl 10 is rotatably connected in the installation groove. By rotating the screw 11, the hose clamp steel strip 6 is tightened to prevent leakage. The screw 11 can be limited by the cooperation of the ratchet 12 and the pawl 10 to prevent the hose clamp from loosening due to machine vibration when the relevant machine is started, which would ultimately cause leakage of modified plastic granules at the connection point of the first installation hose 2 and the second installation hose 4 during feeding.

[0028] Preferably, in this embodiment, a feed hopper 8 is fixedly installed on the lower inner wall of the connecting pipe 5. The feed hopper 8 is funnel-shaped. This design allows the modified plastic particles to enter the first installation hose 2 smoothly. The outer ring of the connecting pipe 5 at the receiving hopper 3 is evenly provided with multiple feed holes 7, so that the modified plastic particles entering from the receiving hopper 3 can fall into the connecting pipe 5 through the feed holes 7. The connecting pipe 5 and the receiving hopper 3 are made of metal. The metal material has high strength and durability and can withstand the impact and friction of the modified plastic particles.

[0029] A V-shaped spring piece 13 is fixedly installed on one side of the mounting groove of the hose clamp head 9. The other side of the V-shaped spring piece 13 is connected to one side wall of the pawl 10. The V-shaped spring piece 13 provides elastic force to the pawl 10, so that the pawl 10 can fit tightly against the ratchet 12 and ensure the tightening effect of the hose clamp.

[0030] Example 2:

[0031] Please see Figure 1 , Figure 2 and Figure 3In this embodiment, during the assembly process, the first installation hose 2 is first fitted onto the outer ring of the top feed pipe of the modified plastic pellet processing machine 1. The connection method between the connecting pipe 5 and the first installation hose 2 and the second installation hose 4 is the same as in embodiment one, so that the connection is firm. In the use of hose clamps, the hose clamp composed of hose clamp steel band 6, hose clamp head 9 and screw 11 is used to tighten the hose. With the cooperation of pawl 10 and ratchet 12, the hose clamp steel band 6 fits more tightly with the hose. Even if the machine vibrates, the occurrence of the hose clamp steel band 6 loosening is greatly reduced.

[0032] The feed hopper 8 on the lower inner wall of the connecting pipe 5 also adopts a funnel-shaped design to facilitate the entry of modified plastic granules into the first installation hose 2, thereby further improving the feeding efficiency of modified plastic granules. The number and size of the feed holes 7 at the receiving hopper 3 of the connecting pipe 5 can be adjusted according to the actual situation. For example, increasing the number of feed holes 7 can allow the modified plastic granules to enter the connecting pipe 5 more smoothly, and the diameter of the feed holes 7 can be enlarged to make it easier to feed the plastic granules.

[0033] In this embodiment, the connecting pipe 5 and the receiving hopper 3 are made of high-strength plastic. High-strength plastic has the advantages of being lightweight and corrosion-resistant, while also meeting the strength requirements of the device. The elasticity of the V-shaped spring 13 can be adjusted as needed, making the fit between the pawl 10 and the ratchet 12 tighter and improving the fastening reliability of the hose clamp.

[0034] Example 3:

[0035] Please see Figure 1 , Figure 2 and Figure 3 In this embodiment, during assembly, a first mounting hose 2 and a second mounting hose 4 of appropriate specifications are selected according to the size of the feed pipe of the processing machine, and are fitted onto the outer ring of the feed pipe. The connection between the connecting pipe 5 and the hose remains firm and reliable.

[0036] The installation and use of the hose clamp are similar to the previous two embodiments, but some optimizations can be made to the design of the hose clamp. For example, a rubber pad can be added to the inside of the hose clamp steel band 6 to improve the sealing between the hose clamp and the hose.

[0037] The feed hopper 8 on the lower inner wall of the connecting pipe 5 can be designed into a special shape, such as an oval or square flared mouth, according to the characteristics of the modified plastic particles and the feeding requirements, so as to better guide the modified plastic particles into the connecting pipe 5. The feed hole 7 of the connecting pipe 5 located at the receiving hopper 3 can adopt different shapes and arrangements, such as increasing the number of feed holes 7 or enlarging the diameter of the feed holes 7, so as to improve the feeding efficiency.

[0038] The connecting pipe 5 and the receiving hopper 3 can be made of a combination of metal and high-strength plastic. For example, the connecting pipe 5 can be made of metal to ensure strength, and the receiving hopper 3 can be made of high-strength plastic to reduce weight.

[0039] Working principle and usage process of this utility model:

[0040] When using this leak-proof device for feeding modified plastic granules, a hose clamp is first used to secure and seal the connection between the first and second installation hoses 2 and adjacent components. By rotating the screw 11, the steel band 6 of the hose clamp is tightened to prevent leakage. The screw 11 is limited by the ratchet 12 and the pawl 10 to prevent the hose clamp from loosening due to machine vibration during machine startup, which could lead to leakage of modified plastic granules at the connection between the first and second installation hoses 2 and 4 during feeding. By connecting the first and second installation hoses 2 and 4 to adjacent components and fixing them with a hose clamp, a flexible connection is achieved at the connection point. This avoids the misalignment caused by vibration during machine startup of traditional rigid connections, which could lead to leakage of modified plastic granules and thus avoid resource waste.

[0041] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
