Description

Technical Field

[0001] This utility model relates to the field of weighing and packaging machines, and specifically to an adjustment mechanism for weighing and packaging machines. Background Technology

[0002] Weighing and packaging machines are key equipment used for quantitative packaging of materials in modern industrial production, and are widely used in many fields such as food, chemical industry, building materials, and grain.

[0003] The weighing and packaging machine mainly consists of three parts working together: packaging equipment, weighing equipment, and material conveying system. The material conveying system undertakes the important task of transporting the materials to be packaged to the designated location. As the key structure of the system, the hopper can stably receive the conveyed materials and accurately put them into the packaging bag, providing a foundation for subsequent accurate weighing.

[0004] However, most weighing and packaging machines currently on the market still have certain limitations in their hoppers. These hoppers mostly use a direct discharge method with a fixed discharge angle, which means they can only feed materials to weighing devices in fixed positions. In actual production, if it is necessary to adjust the position of the weighing device to adapt to different sizes of packaging bags or production processes, the fixed-angle hopper cannot be flexibly adapted, requiring complex adjustments or modifications to the equipment. This results in poor overall flexibility, increased operational difficulty, and reduced production efficiency, making it difficult to meet diverse production needs. Therefore, it is necessary to invent an adjusting mechanism for weighing and packaging machines to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide an adjustment mechanism for a weighing and packaging machine. By setting a sleeve in conjunction with a guide pipe, the material discharged from the hopper can be guided. At the same time, the guide pipe can be rotated horizontally by a rotating ring in conjunction with a connecting plate. This allows for feeding of materials to weighing equipment at different positions. The pitch angle of the guide pipe can be adjusted by the connecting plate to adjust the distance between the guide pipe and the packaging bag. Thus, the material discharge position can be flexibly adjusted according to different specifications of packaging bags or different positions of weighing equipment, solving the problem that it is difficult to adjust the material discharge position according to different specifications of packaging bags or production processes due to the fixed discharge angle of the hopper.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjusting mechanism for a weighing and packaging machine, comprising: A sleeve, wherein a threaded groove is formed on the inner wall of the sleeve, and a rotating ring is rotatably connected to the outer wall of the sleeve; A connecting plate, one end of which is hinged to the inner wall of the rotating ring, and the other end of which is fixedly connected to a guide pipe; The positioning mechanism includes a guide rod, which is fixedly connected to the upper surface of the rotating ring. A spring is sleeved on the outer wall of the guide rod, and a retaining ring is slidably connected to the outer wall of the guide rod. A positioning pin is fixedly connected to the upper surface of the retaining ring, and a retaining plate is fixedly connected to the lower surface of the retaining ring. A chuck is fixedly connected to the outer wall of the sleeve, and a through hole is opened on the inner wall of the chuck. A groove is opened on the inner wall of the connecting plate.

[0007] Preferably, one end of the spring is fixedly connected to the upper surface of the swivel ring, and the other end of the spring is fixedly connected to the lower surface of the retaining ring.

[0008] Preferably, the positioning pin is inserted into the inner wall of the through hole, and the card plate is inserted into the inner wall of the card slot.

[0009] Preferably, the top of the connecting plate has an arc-shaped structure, and at least three sets of slots are equidistantly provided along the arc surface.

[0010] Preferably, at least three sets of through holes are arranged in a circular array with the central axis of the chuck as the center.

[0011] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention utilizes a rotating ring and a connecting plate to drive the guide tube to rotate horizontally, thereby adjusting the feeding position of the guide tube. This allows for feeding to weighing equipment at different locations. The rotation of the connecting plate adjusts the pitch angle of the guide tube, controlling the distance between the guide tube and the packaging bag, thus accommodating packaging bags of different heights. A positioning mechanism further secures the adjusted guide tube. This allows for flexible adjustment of the feeding position according to different packaging bag sizes or weighing equipment locations, greatly improving the flexibility of material weighing and packaging.

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0016] This utility model provides, for example Figure 1 - Figure 4 An adjusting mechanism for a weighing and packaging machine is shown, including a sleeve 1, a connecting plate 2 and a positioning mechanism 3; The inner wall of the sleeve 1 is provided with a threaded groove 4. An external thread matching the threaded groove 4 is provided on the outer wall of the hopper discharge port of the weighing and packaging machine. The sleeve 1 is fixed to the hopper discharge port by the cooperation of the threaded groove 4 and the external thread. The outer wall of the sleeve 1 is rotatably connected with a rotating ring 5. The rotation of the rotating ring 5, in conjunction with the connecting plate 2, can drive the guide pipe 6 to rotate horizontally, thereby adjusting the discharge position of the guide pipe 6. One end of the connecting plate 2 is hinged to the inner wall of the rotating ring 5, and the other end of the connecting plate 2 is fixedly connected to the guide tube 6. The guide tube 6 can be rotated by the connecting plate 2, and the pitch angle of the guide tube 6 can be adjusted to accommodate packaging bags of different heights. The positioning mechanism 3 includes a guide rod 31, which is fixedly connected to the upper surface of the rotating ring 5. The guide rod 31 can limit the rotation of the rotating ring 5, preventing it from continuing to rotate on the outer wall of the sleeve 1. A spring 32 is sleeved on the outer wall of the guide rod 31, and a retaining ring 33 is slidably connected to the outer wall of the guide rod 31. A positioning pin 34 is fixedly connected to the upper surface of the retaining ring 33, which limits the retaining ring 33 and thus limits the guide rod 31. A retaining plate 35 is fixedly connected to the lower surface of the retaining ring 33. A chuck 36 is fixedly connected to the outer wall of the sleeve 1. A through hole 37 is opened on the inner wall of the chuck 36. At least three sets of through holes 37 are opened in a circular array with the central axis of the chuck 36 as the center. The rotating ring 5 can be fixed in multiple different positions by cooperating with the positioning pin 34 through multiple through holes 37. A slot 38 is opened on the inner wall of the connecting plate 2. The top of the connecting plate 2 is an arc-shaped structure. At least three sets of slots 38 are opened at equal intervals along the arc surface. The connecting plate 2 can be fixed at multiple different angles by cooperating with the multiple sets of slots 38 and the chuck 35.

[0017] like Figure 1 - Figure 2As shown, one end of the spring 32 is fixedly connected to the upper surface of the rotating ring 5, and the other end of the spring 32 is fixedly connected to the lower surface of the retaining ring 33. The elasticity of the spring 32 can drive the retaining ring 33 to slide and reset on the outer wall of the guide rod 31.

[0018] like Figure 4 As shown, the positioning pin 34 is inserted into the inner wall of the through hole 37. The positioning pin 34 is driven into the interior of the through hole 37 by the retaining ring 33. The retaining ring 33 can be limited by the chuck 36 in conjunction with the through hole 37 and the positioning pin 34. The retaining plate 35 is inserted into the inner wall of the retaining groove 38. The retaining ring 33 drives the retaining plate 35 into the interior of the retaining groove 38. The retaining plate 35 can be limited by the retaining groove 38.

[0019] The working principle of this practical machine is as follows: First, an external thread matching the threaded groove 4 is opened on the outer wall of the hopper discharge port of the weighing and packaging machine. Then, the sleeve 1 is fixed to the hopper discharge port by using the threaded groove 4 and the external thread. When the material is conveyed into the hopper, the material inside the hopper will fall down into the sleeve 1. At this time, the material inside the sleeve 1 will slide down through the guide pipe 6, thus conveying the material to the packaging bag on the weighing equipment.

[0020] When it is necessary to adjust the feeding position of the guide tube 6, press down on the retaining ring 33 so that it slides down on the outer wall of the guide rod 31 and compresses the spring 32. At this time, the retaining ring 33 will drive the positioning pin 34 to be pulled out from the inside of the through hole 37. After the positioning pin 34 is disengaged from the inside of the through hole 37, the limit on the retaining ring 33 can be released. At this time, the retaining ring 33 can be rotated so that the retaining ring 33 pushes the guide rod 31. At this time, the guide rod 31 will drive the rotating ring 5 to rotate horizontally on the outer wall of the sleeve 1. At the same time, the rotating ring 5 will drive the connecting plate 2 to move synchronously. At this time, the connecting plate 2 will drive the guide tube 6 to rotate horizontally. In this way, the feeding position of the guide tube 6 can be adjusted, and thus the weighing equipment at different positions can be fed. After adjustment, align the positioning pin 34 with the through hole 37, and then release the retaining ring 33. At this time, the previously compressed spring 32 will push the retaining ring 33 to slide upward and reset on the outer wall of the guide rod 31. At the same time, the retaining ring 33 will drive the positioning pin 34 to insert into the inside of the through hole 37. At this time, the retaining ring 33 can be limited by the chuck 36 in conjunction with the through hole 37 and the positioning pin 34. At the same time, the rotating ring 5 can be limited by the guide rod 31, so that the rotating ring 5 cannot continue to rotate on the outer wall of the sleeve 1. In this way, the position of the adjusted guide tube 6 can be fixed.

[0021] When it is necessary to adjust the feeding angle of the guide tube 6, push the retaining ring 33 upward so that it slides upward on the outer wall of the guide rod 31 and stretches the spring 32 until the retaining ring 33 drives the retaining plate 35 to be pulled out from the inside of the retaining groove 38. At this time, the retaining plate 35 will release the limit on the connecting plate 2. Then rotate the connecting plate 2 to adjust the pitch angle of the guide tube 6. By adjusting the pitch angle of the guide tube 6, the distance between it and the packaging bag can be controlled, so as to adapt to packaging bags of different heights. After the pitch angle of the guide tube 6 is adjusted, align the clamping plate 35 with the clamping groove 38, and then release the clamping ring 33. At this time, the previously stretched spring 32 will pull the clamping ring 33, causing the clamping ring 33 to slide downward on the outer wall of the guide rod 31. At this time, the clamping ring 33 will drive the clamping plate 35 to be inserted into the inside of the clamping groove 38 again. At this time, the clamping plate 35 and the clamping groove 38 can be used to limit the connection plate 2, thus limiting the guide tube 6 after the angle is adjusted.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
