Description

Technical Field

[0001] This utility model relates to the field of screw feeder technology, and in particular to a quick-assembly and disassembly structure for a screw feeder cylinder. Background Technology

[0002] Screw feeders are a common type of industrial conveying equipment, widely used in industries such as chemical, food, pharmaceutical and building materials. They are mainly used to convey powdery, granular or small lump materials. The core structure includes a drive motor, a feeding cylinder and a spiral auger rod located inside the feeding cylinder. The material is pushed to move along the axial direction of the feeding cylinder by the rotation of the spiral auger rod, thereby realizing the feeding function.

[0003] In actual production processes, especially in the food and pharmaceutical industries, in order to prevent material residues from causing deterioration or cross-contamination, it is necessary to frequently and thoroughly clean and disinfect the inside of the feed cylinder and the spiral auger rod of the screw feeder. However, in order to ensure the sealing and stability of the screw feeder during operation, the end caps at both ends of the feed cylinder are fixed to the cylinder body with flanges and multiple bolts. At the same time, the feed cylinder and the frame are mostly fixed by bolts or welding.

[0004] This traditional connection method requires operators to use wrenches and other tools to remove a large number of bolts one by one during cleaning and maintenance. Not only is the disassembly and reassembly process tedious and time-consuming, significantly reducing the maintenance efficiency of the equipment, but frequent disassembly and reassembly can also lead to stripped or lost bolts, which in turn affects the tightness of the equipment connection and its service life, making it difficult to meet the needs of modern production for rapid cleaning and efficient maintenance of equipment.

[0005] Therefore, this utility model proposes a quick-assembly and disassembly structure for a screw feeder to address the shortcomings of the prior art. Utility Model Content

[0006] In the existing technology, the screw feeder cylinder end cover and cylinder body are generally connected to the frame by bolts, which leads to problems such as cumbersome and time-consuming disassembly and assembly process when frequent cleaning and maintenance are required, low maintenance efficiency, and easy loss or damage of parts. The present invention aims to provide a screw feeder cylinder quick disassembly and assembly structure with improved structure that can effectively solve the above problems.

[0007] This utility model provides a quick-assembly and disassembly material cylinder structure for a screw feeder, including: a support frame, and a feeding cylinder disposed on the top of the support frame. Both ends of the feeding cylinder are rotatably fitted with connecting discs. The inside of the feeding cylinder is provided with a spiral auger rod, and both ends of the spiral auger rod are rotatably connected to the two connecting discs respectively. It also includes a plug, a slot, a groove, a plug rod, a spring, and a reserved hole.

[0008] The feed cylinder has an insert block fixedly connected to its outer wall. The connecting plate has a slot on the side facing the feed cylinder. The insert block is inserted into the slot. The connecting plate has a sliding groove on its inner wall. An insert rod is slidably connected to the inner wall of the sliding groove. A spring is fixedly connected to one end of the insert rod. The end of the spring away from the insert rod abuts against the inner wall of the sliding groove. A reserved hole is opened in the middle of the insert block. The insert rod passes through the reserved hole under the elastic force of the spring and engages with the reserved hole to prevent the connecting plate from detaching from the feed cylinder.

[0009] Preferably, a lever is fixedly connected to the outer wall of the insertion rod. The lever penetrates and extends out of the outer surface of the connecting plate. By pushing the lever, the insertion rod slides in the groove and squeezes the spring, causing the insertion rod to disengage from the reserved hole.

[0010] Preferably, the top of the support frame is provided with a fixing mechanism, which includes a fixing seat fixedly connected to the top of the support frame and a vertical plate fixedly connected to the top of the fixing seat.

[0011] Preferably, a rotating ring is rotatably connected to the top of the upright plate located on the front side, a hook is fixedly connected to the rear side of the rotating ring, and a fastener is fixedly connected to the outer wall of the upright plate located on the rear side, with the hook engaging with the fastener.

[0012] Preferably, a limiting block is fixedly connected to the outer wall of the feeding cylinder. The limiting block engages with the rotating ring. The rotating ring presses the limiting block onto the fixed seat through the engagement of the hook and the buckle, thereby fixing the position of the feeding cylinder.

[0013] Preferably, a motor is fixedly connected to the top of the support frame, and a coupling is slidably connected to the output end of the motor. The end of the coupling away from the motor is slidably connected to one end of the spiral auger rod. The coupling is used to realize the power transmission and axial separation between the motor and the spiral auger rod.

[0014] Preferably, there are two insert blocks, which are symmetrically fixed on the left and right sides of the outer wall of the feed cylinder, and two connecting discs are correspondingly set, located on the left and right sides of the feed cylinder.

[0015] Preferably, the insert block, the slot, the slide groove, the insert rod, the spring, the paddle, and the reserved hole together constitute the quick replacement mechanism of the quick disassembly and assembly cylinder structure of the screw feeder, and the fixed base, the upright plate, the rotating ring, the hook, and the latch together constitute the fixing mechanism of the quick disassembly and assembly cylinder structure of the screw feeder.

[0016] This utility model has the following beneficial effects: 1. This utility model solves the problem that the disassembly of the end cover of the feed cylinder of the existing screw feeder requires tools and is cumbersome by setting a quick replacement mechanism between the feed cylinder and the connecting plate. It utilizes the interlocking cooperation between the insert block and the slot, combined with the self-locking function of the insert rod under the action of spring force and the unlocking function driven by the paddle, thus achieving the effect of quick disassembly and assembly of the connecting plate by hand and improving the efficiency of equipment cleaning and maintenance.

[0017] 2. This utility model solves the problems of simple material cylinder fixing methods and inconvenient disassembly in the prior art by setting a fixing mechanism between the support frame and the feeding cylinder, and by using the locking structure of the rotating ring, the hook and the latch, and the engagement of the rotating ring and the limiting block. It achieves the effect of quickly and firmly locking the material cylinder on the frame, and at the same time, it can be quickly unlocked when needed to facilitate the removal of the entire material cylinder for deep cleaning.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0022] Example: Please refer to Figures 1 to 8 This utility model provides a quick-disassembly and assembly structure for a screw feeder, which aims to solve the problem that the screw feeder in the prior art is mostly connected to the frame and end cap with bolts, which makes disassembly and cleaning cumbersome and time-consuming.

[0023] Please refer to Figure 1 , Figure 2 and Figure 3 A quick-assembly and disassembly cylinder structure for a screw feeder includes a support frame 1 and a feeding cylinder 4 disposed on top of the support frame 1. The support frame 1 serves as the mounting base for the entire feeder device to provide stable support. The feeding cylinder 4 is used to contain the material to be conveyed and to provide installation space for internal components. A screw auger 6 is disposed inside the feeding cylinder 4. The screw auger 6 is used to push the material for conveying when rotating. Connecting discs 5 are rotatably fitted at both ends of the feeding cylinder 4. The two connecting discs 5 are respectively sealed at the openings on the left and right sides of the feeding cylinder 4. The left and right ends of the screw auger 6 are rotatably connected to the two connecting discs 5, which provide support and positioning for the screw auger 6. A motor 7 is fixedly connected to the top of the support frame 1. The motor 7 serves as a power source to drive the screw auger 6 to rotate. A coupling 8 is slidably connected to the output end of the motor 7. The end of the coupling 8 away from the motor 7 is slidably connected to the left end of the screw auger 6. The coupling 8 is used to realize the power transmission between the motor 7 and the screw auger 6 and axial separation during disassembly.

[0024] Please refer to Figure 5 and Figure 6The quick-change mechanism 2 includes two insert blocks 201 fixedly connected to the left and right sides of the outer wall of the feed cylinder 4, which are symmetrically distributed. A slot 202 is provided on the side of the connecting plate 5 facing the feed cylinder 4. The shape of the slot 202 is adapted to the insert block 201. In the assembled state, the insert block 201 is inserted into the slot 202. A groove 203 is provided on the inner wall of the connecting plate 5. An insert rod 204 is slidably connected to the inner wall of the groove 203. The insert rod 204 can slide radially back and forth within the groove 203. A spring 205 is fixedly connected to one end of the insert rod 204, and the end of the spring 205 away from the insert rod 204 abuts against and is fixed thereon. The insert block 201, connected to the inner wall of the slide 203, has a pre-drilled hole 207 in the middle. The insert rod 204 passes through the pre-drilled hole 207 under the elastic force of the spring 205 and engages with the pre-drilled hole 207. This matching structure of the insert rod 204 and the pre-drilled hole 207 ensures that the connecting plate 5 will not easily detach from the feeding cylinder 4 after installation. At the same time, a lever 206 is fixedly connected to the outer wall of the insert rod 204. The lever 206 penetrates and extends out of the outer surface of the connecting plate 5. By manually pushing the lever 206, the insert rod 204 can slide in the slide 203 and squeeze the spring 205, thereby causing the insert rod 204 to disengage from the pre-drilled hole 207 to achieve unlocking.

[0025] As a preferred embodiment, in order to achieve quick fixing and disassembly between the feed cylinder 4 and the support frame 1, a quick-disassembly and assembly structure for a screw feeder also includes a fixing mechanism 3. Please refer to... Figure 4 and Figure 7 The fixing mechanism 3 includes two fixing seats 302 fixedly connected to the top of the support frame 1, arranged in a front-to-back configuration. A vertical plate 303 is fixedly connected to the top of each fixing seat 302. A rotating ring 304 is rotatably connected to the top of the front vertical plate 303, allowing it to rotate in a vertical plane. A hook 305 is fixedly connected to the rear side of the rotating ring 304, and a latch 306 is fixedly connected to the outer wall of the rear vertical plate 303. The hook 305 can engage with the latch 306. (See also...) Figure 8 A limiting block 301 is fixedly connected to the outer wall of the feeding cylinder 4. The shape of the limiting block 301 matches the rotating ring 304. In the fixed state, the limiting block 301 and the rotating ring 304 engage. The rotating ring 304 presses the limiting block 301 onto the fixed seat 302 through the engagement of the hook 305 and the latch 306, thereby limiting the axial and radial displacement of the feeding cylinder 4 on the fixed seat 302. This clamp-type fixing method greatly improves the stability of the feeding cylinder 4 and the convenience of disassembly and assembly.

[0026] Working principle: When feeding is required, the motor 7 starts and drives the coupling 8 to rotate. The coupling 8 drives the spiral auger rod 6 to rotate inside the feeding cylinder 4 to transport materials. When disassembly and cleaning are required, the operator first rotates the rotating ring 304 to separate the hook 305 on the rotating ring 304 from the buckle 306 on the upright plate 303. Then, the rotating ring 304 is flipped upward to separate from the limiting block 301 on the feeding cylinder 4, releasing the locking mechanism 3 from the feeding cylinder 4. Next, the operator presses the paddle 206 in the middle of the connecting plate 5. The paddle 206 drives the insertion rod 204 to slide in the slide groove 203 and compress the spring 205, so that the insertion rod 204 exits from the reserved hole 207 on the insertion block 201. At this time, the quick-change mechanism 2 is in the unlocked state, and the operator can remove the connecting plate 5 from the feeding cylinder 4. Since the motor 7 and the spiral auger rod 6 are slidably connected by the coupling 8, the operator can directly remove the feeding cylinder 4 together with the spiral auger rod 6 from the support frame 1, or pull the spiral auger rod 6 out of the feeding cylinder 4 for cleaning. The installation process is the reverse of the above steps. First, retract the insert rod 204 by using the lever 206, align the slot 202 of the connecting plate 5 with the insert block 201 of the feeding cylinder 4 and insert it. Release the lever 206 and it will automatically lock under the action of the spring 205. Then, place the feeding cylinder 4 on the fixed seat 302, use the rotating ring 304 to hold the limit block 301 and lock it with the hook 305. The whole process does not require the use of screwdrivers or other tools, which greatly improves work efficiency.
