Description

Technical Field

[0001] This application relates to the field of vacuum feeder technology, specifically a separate vacuum feeder. Background Technology

[0002] A vacuum conveyor is a dust-free, closed-loop pipeline conveying device that uses vacuum suction to transport granular and powdery materials. It utilizes the pressure difference between the vacuum and the ambient space to create gas flow within the pipeline, which in turn moves the powdery materials, thus completing the conveying of the powder. This method can eliminate dust pollution, improve the working environment, and reduce environmental and personnel contamination of materials, thereby increasing cleanliness. As a result, it is widely used in the conveying of powders and granules.

[0003] A separate vacuum feeder, application number CN202021122619.7, includes a housing, a vacuum pump fixedly connected to the top of the housing, a filter element fixedly connected to the inner wall of the housing near the vacuum pump, a compressed air backflushing device provided between the filter element and the vacuum pump, a protective net fixedly connected to the inner wall of the housing at the bottom of the filter element, a discharge pipe fixedly connected to the bottom of the housing, and a flexible hose fixedly connected to the center part of one side of the housing.

[0004] However, most vacuum feeders currently on the market are still integrated units. But integration has certain drawbacks. During the production process, different batches of materials may differ. If the hopper and the feeding shell are not detachable, it is not easy to clean the inside when changing the type of material. This can lead to old material remaining in corners and gaps being mixed with new material, causing cross-contamination and affecting product quality. The aforementioned separate vacuum feeder has the above-mentioned shortcomings. It is not convenient to detach and assemble the feeding hopper and the feeding shell, which makes cleaning the inside of the feeding hopper and the feeding shell somewhat cumbersome.

[0005] Therefore, it is necessary to provide a separate vacuum feeder to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Utility Model Content

[0007] Based on the aforementioned problems in the existing technology, the problem to be solved by this application is to provide a separable vacuum feeder, which solves the problem that the integrated vacuum feeder is inconvenient to disassemble and separate.

[0008] The technical solution adopted by this application to solve its technical problem is: a separate vacuum feeder, including a vacuum feeder body, a snap-fit ​​assembly provided on the vacuum feeder body, a feeding control box connected to the surface of the vacuum feeder body, a feeding pipe connected to the surface of the feeding control box, a feeding gun connected to one end of the feeding pipe, a feeding hopper snap-fitted to the top of the vacuum feeder body, a fixing ring connected to the surface of the feeding hopper, and three receiving grooves opened on the surface of the fixing ring; The surface of the snap-fit ​​assembly is connected to the inner side of the vacuum feeder body to connect and install the vacuum feeder body with the feed hopper.

[0009] Furthermore, the snap-fit ​​assembly includes three limiting rods, three connecting discs, three limiting slots, and four fixing blocks. The three limiting rods are slidably disposed on the inner side of the top of the vacuum feeder body. One end of each of the three limiting rods is connected to a limiting block. The three connecting discs are respectively disposed on the other end of the three limiting rods. A retraction spring is sleeved on the outer side of each of the three limiting rods. The three limiting slots are opened on the inner side of the vacuum feeder body. The four fixing blocks are disposed on the surface of the fixing ring. Fastening bolts are threadedly connected to the inner side of each of the four fixing blocks.

[0010] Furthermore, the cross-section of each of the limiting blocks, the cross-section of each of the limiting slots, and the cross-section of each receiving slot are all rectangular, and the surfaces of the three limiting blocks are slidably connected to the inner sides of the three limiting slots respectively.

[0011] Furthermore, the surfaces of the three limiting blocks are respectively engaged with the inner sides of the three receiving slots.

[0012] Furthermore, both ends of each of the contraction springs are connected to the surface of each of the connecting discs and the surface of the vacuum feeder body, respectively.

[0013] Furthermore, the surfaces of the four fastening bolts are all threadedly connected to the inner top of the vacuum feeder body.

[0014] Furthermore, the bottom end of the fixing ring is attached to the top end of the vacuum feeder body.

[0015] The beneficial effects of this application are: the separate vacuum feeder provided by this application, 1. The sliding limit lever facilitates the separation of the limit block from the receiving groove, making it easy to separate the feeding hopper from the vacuum feeding machine body for hopper replacement. The elastic contraction of the compression spring facilitates the engagement of the limit block with the receiving groove, making it easy to align the new feeding hopper with the installation position of the vacuum feeding machine body. This eliminates the need for operators to painstakingly match the subsequent threaded installation position, thus improving the efficiency of installation and disassembly. 2. By screwing the four fastening bolts into the four fixing blocks and the vacuum feeder body respectively, the installation and separation of the feeding hopper and the vacuum feeder body can be completed simply and quickly. Separating the feeding hopper from the vacuum feeder body helps to avoid material residue and cross-contamination, ensuring that the product quality meets the standard quality and hygiene specifications. In addition, the split structure facilitates quick disassembly of the vacuum feeder body and the feeding hopper when internal components malfunction, allowing maintenance personnel to more accurately determine the cause of the malfunction and improve maintenance efficiency.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0020] like Figure 1-4 As shown, this application provides a separate vacuum feeder, including a vacuum feeder body 1, a snap-fit ​​assembly 2 on the vacuum feeder body 1, a feeding control box 3 connected to the surface of the vacuum feeder body 1, a feeding pipe 4 connected to the surface of the feeding control box 3, a feeding gun 5 connected to one end of the feeding pipe 4 to facilitate material extraction for feeding, a feeding hopper 6 snap-fitted to the top of the vacuum feeder body 1, a fixing ring 7 connected to the surface of the feeding hopper 6, and three receiving grooves 8 opened on the surface of the fixing ring 7 to facilitate subsequent positioning and fixing; The surface of the snap-fit ​​assembly 2 is connected to the inside of the vacuum feeder body 1 for docking and installing the vacuum feeder body 1 with the feed hopper 6.

[0021] The locking assembly 2 includes three limiting rods 21, three connecting discs 23, three limiting slots 25, and four fixing blocks 26. The three limiting rods 21 are all slidably disposed on the inner side of the top of the vacuum feeder body 1. One end of each of the three limiting rods 21 is connected to a limiting block 22 for easy positioning and locking. The three connecting discs 23 are respectively disposed on the other end of the three limiting rods 21 for easy gripping. The outer side of each of the three limiting rods 21 is fitted with a retraction spring 24. The three limiting slots 25 are all opened on the inner side of the vacuum feeder body 1. The four fixing blocks 26 are all disposed on the surface of the fixing ring 7. The inner side of each of the four fixing blocks 26 is threaded with a fastening bolt 27 for easy threaded fixing.

[0022] Furthermore, the cross-section of each limiting block 22, the cross-section of each limiting slot 25, and the cross-section of each receiving slot 8 are all rectangular. The surfaces of the three limiting blocks 22 are slidably connected to the inner sides of the three limiting slots 25, so that the vacuum feeder body 1 and the feed hopper 6 can be connected and installed by engaging the limiting blocks 22 and the limiting slots 25.

[0023] The surfaces of the three limiting blocks 22 engage with the inner sides of the three receiving slots 8 respectively, which facilitates improved docking performance.

[0024] Both ends of each retraction spring 24 are connected to the surface of each connecting disc 23 and the surface of the vacuum feeder body 1, respectively, so as to facilitate the engagement of the drive limit block 22 with the corresponding receiving groove 8.

[0025] The surfaces of the four fastening bolts 27 are all threaded to the inner top of the vacuum feeder body 1, which facilitates the tightening of the vacuum feeder body 1 and the feed hopper 6.

[0026] The bottom end of the fixing ring 7 fits into the top end of the vacuum feeder body 1, which facilitates the fixing ring 7 to support the feed hopper 6, thereby helping to improve the stability of the feed hopper 6 and the vacuum feeder body 1 during installation.

[0027] Working principle: First, the operator pulls the limiting rod 21, which is slidably connected to the inside of the vacuum feeder body 1, outward, causing the three limiting blocks 22 to slide back into the limiting slots 25. Then, the feeding hopper 6 is placed from top to bottom into the top of the vacuum feeder body 1 until the bottom end of the fixing ring 7 on the feeding hopper 6 is in contact with the top of the vacuum feeder body 1. At this point, it should be noted that since the receiving slot 8 and the limiting rod 21 are both located in a visible position, the receiving slot 8 and the limiting rod 21 can be accurately and quickly connected. With the positions corresponding, the fixing ring 7 and the feeding hopper 6 are placed on the top of the vacuum feeding machine body 1. After the feeding hopper 6 is aligned with the vacuum feeding machine body 1, the three limiting rods 21 are released. At this time, under the contraction action of the three retraction springs 24, the limiting rods 21 and the limiting blocks 22 are reset and retracted into the inside of the limiting slots 25, and the three limiting blocks 22 are engaged with the inner side of the three receiving slots 8. The engagement of the three limiting blocks 22 with the three receiving slots 8 facilitates subsequent threaded fixing. After quickly positioning the feeding hopper 6 and the vacuum feeding machine body 1, the operator screws the four fastening bolts 27 into the four fixing blocks 26 and the vacuum feeding machine body 1 respectively, thus completing the installation and separation of the feeding hopper 6 and the vacuum feeding machine body 1 simply and quickly. Separating the feeding hopper 6 and the vacuum feeding machine body 1 helps to avoid material residue and cross-contamination, ensuring that the product quality meets the standard quality and hygiene specifications. In addition, the split structure facilitates quick disassembly of the vacuum feeding machine body 1 and the feeding hopper 6 when internal components malfunction, allowing maintenance personnel to more accurately determine the cause of the malfunction and improve maintenance efficiency.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
