Description

Technical Field

[0001] This utility model belongs to the field of glass machinery technology, specifically relating to a multi-drop shearing system for a feeder. Background Technology

[0002] The feeding machine is one of the common pieces of equipment in the glass bottle making machinery field. The shearing system is the main component of the feeding machine. The shearing system is equipped with relatively moving scissor handles. At least one set of scissor blades are respectively arranged on the relatively moving scissor handles. When the two scissor handles move relative to each other, the relatively moving scissor blades cut the material into droplets of a predetermined size.

[0003] Taking a five-drop scissor handle assembly as an example, there are generally three types on the market: 1. A set of scissor blades with five cutting edges on the scissor handle; 2. Three sets of scissor blades on the scissor handle, one set with three cutting edges and the other two sets with one cutting edge; 3. Three sets of scissor blades on the scissor handle, one set with one cutting edge and the other two sets with two cutting edges. Meanwhile, currently available four-drop, five-drop, and six-drop material support assemblies generally only come with one material support plate. There are also two-drop, three-drop, and four-drop material support assemblies with two, three, or four material support blocks respectively. To allow for adjustments without stopping the machine, two or three material support arms are arranged parallel to the right scissor arm.

[0004] Therefore, single-blade shear blades cannot be adjusted for parallelism or blade height, resulting in a lack of flexibility in the use of a single pair of shear blades for adjusting parallelism and shearing tension. Furthermore, the current feeder shear system faces a contradictory problem: multi-blade shear blades offer a simple overall material support plate structure, but cannot achieve independent adjustment of individual material droplets; while single-blade shear blades, independent material support plates, or material support blocks offer good functionality, but are too heavy, and their high-speed operation can damage the drive system. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a simple multi-drop shearing system for a feeder, which can independently adjust the parallelism and shearing tension of each pair of shear blades.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a multi-drop cutting system for a feeder, comprising a left scissor handle and a right scissor handle arranged opposite to and spaced apart. Multiple left scissor handles and multiple right scissor handles are respectively provided on the left and right scissor handles, with the left and right scissor handles corresponding to each other. A single-bladed scissor blade is fixedly installed at the front end of each left and right scissor handle. The opposing scissor blades on the left and right scissor handles are staggered vertically. Each left scissor handle is rotatably mounted on the left scissor handle, with its rotation axis parallel to the length direction of the scissor handle. Each right scissor handle is rotatably mounted on the right scissor handle, with its rotation axis perpendicular to the rotation axis of the left scissor handle. A material support plate is provided below each right scissor handle, and each material support plate is adjustablely mounted on the right scissor handle in a direction close to or away from the scissor blade.

[0007] Preferably, a left pin is provided between the left scissor handle and each left scissor shank. The left pin is provided along the length of the scissor handle. There are corresponding mounting grooves on the left scissor handle and the left scissor shank. The left pin is installed in the mounting grooves on the left scissor handle and the left scissor shank. The left scissor shank is fixedly installed on the left scissor handle by two left fixing bolts, and the two left fixing bolts are respectively installed on both sides of the left pin.

[0008] Preferably, a right pin is provided between the right scissor handle and each right scissor shank. The right pin is provided along the length of the scissor shank. A mounting groove is provided on the right scissor handle and the right scissor shank. The right pin is installed in the mounting groove on the right scissor handle and the right scissor shank. The right scissor shank is fixedly installed on the right scissor handle by two right fixing bolts, and the two right fixing bolts are respectively installed on both sides of the right pin.

[0009] Preferably, all the mounting slots are arc-shaped slots, and when the left scissor handle is horizontally installed above the left scissor handle, there is a gap between the left scissor handle and the left scissor handle; when the right scissor handle is horizontally installed above the right scissor handle, there is a gap between the right scissor handle and the right scissor handle.

[0010] Preferably, the right pin is positioned along the centerline of the corresponding shear blade length direction.

[0011] Preferably, the material support plate is fixedly connected to one end of the adjusting shaft, the other end of the adjusting shaft is provided with an external thread, a handle is connected to the other end of the adjusting shaft, the handle is provided with an internal thread, the other end of the adjusting shaft is connected to the handle, and the external thread of the adjusting shaft and the internal thread of the handle are in the same direction. The handle is installed on the right scissor handle, and the material support plate is also connected to a guide assembly.

[0012] Preferably, a plurality of mounting holes are provided on the right scissor handle, and a bushing is installed in the mounting holes, with one end of the handle installed in the bushing.

[0013] Preferably, the guiding component is a guide shaft, which is set parallel to the adjusting shaft. One end of the guide shaft is fixedly connected to the material support plate, and the other end of the guide shaft is slidably connected to the right scissor handle.

[0014] Preferably, a spring is sleeved on the outside of the adjusting shaft, and the spring is disposed between the material support plate and the right scissor handle.

[0015] Preferably, the material support plate is inclined on the side near the cutting edge, and the upper side of the material support plate is inclined toward the cutting edge.

By adjusting the right scissor handle, the right scissor blade blade can be adjusted left and right, that is, the parallelism of the opposite pair of scissor blade blades can be adjusted. Each material drop can be adjusted individually by the single-blade scissor blade. In addition, the material support plate below the right scissor handle of this utility model can also be adjusted independently to ensure that the final material drop is of better quality.

[0018] 2. This utility model uses the adjusting shaft thread to adjust the position of the material support plate.

Detailed Implementation

[0024] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0025] like Figures 1-2 As shown, this utility model discloses a multi-drop shearing system for a feeder, comprising a left scissor handle 1 and a right scissor handle 2 arranged opposite to each other and spaced apart. The two scissor handles move relative to each other. Multiple left scissor blades 3 and multiple right scissor blades 4 are respectively and correspondingly arranged on the left scissor handle 1 and the right scissor handles 2. The left scissor blades 3 and right scissor blades 4 are arranged side-by-side on the scissor handles. A single-blade scissor blade 11 is fixedly installed at the front end of each left scissor handle 3 and right scissor handle 4. The scissor blades 11 are fixedly installed at the front end of the scissor handle by two mounting bolts 7. A pair of opposite scissor blades 11 on the left scissor handle 1 and the right scissor handle 2 are staggered vertically. Each left scissor handle 3 is rotatably mounted on the left scissor handle 1. The rotation axis of the left scissor handle 3 is parallel to the length direction of the scissor handle. By adjusting the left scissor handle 3, the height of the front edge 17 of the left scissor blade 11 can be adjusted, that is, the shearing pressure can be adjusted. Each right scissor handle 4 is rotatably mounted on the right scissor handle 2. The rotation axis of the right scissor handle 4 is perpendicular to the rotation axis of the left scissor handle 3. By adjusting the right scissor handle 4, the edge 17 of the right scissor blade 11 can be adjusted left and right, that is, the parallelism of the edge 17 of the opposite pair of scissor blades 11 can be adjusted. A material support plate 12 is provided below each right scissor handle 4. Each material support plate 12 is rotatably mounted on the right scissor handle 2 in the direction of approaching or moving away from the scissor blade 11. The material support plate 12 can also be adjusted independently to ensure that a better quality droplet is ultimately provided.

[0026] In this embodiment, five scissor handles are provided on both the left scissor handle 1 and the right scissor handle 2. The scissor handles are installed on the upper side of the scissor handles. A left pin 9 is provided between the left scissor handle 1 and each left scissor handle 3. Each left scissor handle 3 is installed independently. The left pin 9 is set along the length direction of the scissor handle. A corresponding mounting groove is provided on the left scissor handle 1 and the left scissor handle 3. The mounting groove is an arc-shaped groove. The left pin 9 is installed in the mounting groove on the left scissor handle 1 and the left scissor handle 3. When the left scissor handle 3 is installed horizontally above the left scissor handle 1, there is a gap between the left scissor handle 3 and the left scissor handle 1. 3. The scissor blade 1 is fixedly mounted on the left scissor handle 1 by two left fixing bolts 5. The two left fixing bolts 5 are respectively installed on both sides of the left pin 9. When it is necessary to adjust the height of the scissor blade 11 at the front end of the left scissor handle 3, loosen the front left fixing bolt 5 and tighten the rear left fixing bolt 5. This will raise the front scissor blade 11 upward. Conversely, tighten the front left fixing bolt 5 and loosen the rear left fixing bolt 5. This will lower the front scissor blade 11 downward. Therefore, the gap between the scissor blade 11 on the left scissor handle 1 and the scissor blade 11 on the right scissor handle 2 will be adjusted, thus adjusting the shearing pressure. The left fixing bolt 5 can be installed from the top or the bottom. When installed from the bottom, it can pass through the left scissor handle 1 and be directly threaded onto the left scissor handle 3, or it can pass through the left scissor handle 1 and the left scissor handle 3 in sequence and then be fixed with a nut. In this embodiment, the left fixing bolt 5 passes through the left scissor handle 1 from the bottom and is then threaded onto the left scissor handle 3.

[0027] A right pin 10 is provided between the right scissor handle 2 and each right scissor handle 4. Each right scissor handle 4 is also installed independently. The right pin 10 is set along the length of the scissor handle and is perpendicular to the left pin 9. Corresponding mounting grooves are provided on the right scissor handle 2 and the right scissor handle 4. The right pin 10 is installed in the mounting grooves on the right scissor handle 2 and the right scissor handle 4. When the right scissor handle 4 is horizontally installed above the right scissor handle 2, there is a gap between the right scissor handle 4 and the right scissor handle 2, allowing for adjustment. The right scissor handle 4 is secured by two right fixing bolts 6. The right scissor handle 2 is fixedly mounted on the right scissor handle 2, and the two right fixing bolts 6 are respectively installed on both sides of the right pin 10. When it is necessary to adjust the level of the scissor blade 11 at the front end of the right scissor handle 4, loosen one side of the right fixing bolt 6 and tighten the other side of the right fixing bolt 6. This will cause the scissor blade 11 on one side to lift up and tilt. Conversely, tighten one side of the right fixing bolt 6 and loosen the other side of the right fixing bolt 6. This will cause the scissor blade 11 on the other side to lift up and tilt. Therefore, the parallelism between the scissor blade 11 on the left scissor handle 1 and the scissor blade 11 on the right scissor handle 2 will be adjusted. In this embodiment, the right fixing bolt 6 is installed from the top, passes through the right scissor handle 2 and the right scissor handle 4 in sequence, and is fixed by a nut.

[0028] The right pin 10 is set along the centerline of the length direction of its corresponding scissor blade 11. At the same time, due to the reduction of the gap between the scissor blades 11, each scissor blade 11 is set adjacent to each other in sequence. The width of the right scissor handle 4 is limited, but a right fixing bolt 6 needs to be set on each side of the right pin 10. Therefore, the two right fixing bolts 6 cannot be set side by side. The two fixing bolts 6 are set staggered. A clearance opening is set on one side of the right scissor handle 4, and a mounting part is set on the other side of its row. One right fixing bolt 6 is installed next to the clearance opening, and the other right fixing bolt 6 is installed in the mounting part. The mounting part of the previous right scissor handle 4 is intermittently locked in the clearance opening of the adjacent right scissor handle 4.

[0029] like Figures 3-4 As shown, in this embodiment, the scissor blade 11 on the right scissor handle 2 is set higher than the scissor blade 11 on the left scissor handle 2. The material support plate 12 is installed on the lower side of the right scissor blade 11. The material support plate 12 is fixedly connected to one end of the adjusting shaft 13. The other end of the adjusting shaft 13 is provided with an external thread. A handle 16 is connected to the other end of the adjusting shaft 13. The handle 16 is provided with an internal thread. The other end of the adjusting shaft 13 is connected to the handle 16, and the external thread of the adjusting shaft 13 and the internal thread of the handle 16 are in the same direction. Several mounting holes are opened on the right scissor handle 2. A bushing 8 is installed in the mounting holes. One end of the handle 16 is installed in the bushing 8. The handle 16 passes through the bushing 8 and is installed on the right scissor handle 2. The material support plate 12 is also connected to a guide assembly. Rotating the handle 16 causes the adjusting shaft 13 to move along the length direction, thereby adjusting the position of the material support plate 12 at one end of the adjusting shaft 13.

[0030] In this embodiment, the guiding component is a guide shaft 14, which is parallel to the adjusting shaft 13. One end of the guide shaft 14 is fixedly connected to the material support plate 12, and the other end slides through the bushing 8. Springs 15 are sleeved on the outside of both the adjusting shaft 13 and the guide shaft 14, and are positioned between the material support plate 12 and the right scissor handle 2. In this embodiment, the material support plate 12 is fixedly connected to the connecting plate 18, and both the adjusting shaft 13 and the guide shaft 14 are connected to the connecting plate 18. The springs 15 press against one side of the connecting plate 18. Furthermore, in this embodiment, the material support plate 12 is inclined on the side closest to the cutting edge 17, and the upper side of the material support plate 12 is inclined at a certain angle towards the cutting edge 17. This angle can be adjusted in advance to reduce the contact area with the material droplet while ensuring that the material droplet falls vertically. The material support plate 12 can also be made into an arc shape to better fit the material droplet.

[0031] In use, the left and right scissor blades 11 move relative to each other, cutting material droplets. When adjusting the cutting pressure, the height of the scissor blade 11 at the front end of the left scissor handle 3 is adjusted by loosening or tightening the left fixing bolt 5, which raises or lowers the front scissor blade 11. The gap between the scissor blade 11 on the left scissor handle 1 and the scissor blade 11 on the right scissor handle 2 is adjusted. When adjusting the level of the scissor blade 11 at the front end of the right scissor handle 4, the right fixing bolt 6 is loosened or tightened, which raises or lowers one scissor blade 11 or the other scissor blade 11. The parallelism between the scissor blade 11 on the left scissor handle 1 and the scissor blade 11 on the right scissor handle 2 is adjusted. At the same time, each handle 16 can be rotated to adjust each material support plate 12 individually, ensuring that a better quality material droplet is provided. The lightweight adjustment mechanism greatly reduces the weight, has a simple structure, and extends the service life. In addition, it also extends the service life of the drive mechanism.

[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its scope of protection shall still fall within the protection scope of this utility model.
