Description

Technical Field

[0001] This utility model relates to the field of shearing blade disassembly and assembly technology, and specifically to a shearing roller blade disassembly and assembly tool. Background Technology

[0002] The shearing roller is one of the core components of the cutting system in tobacco cigarette manufacturing production lines (such as the PROTOS M8 cigarette machine, ZJ112 cigarette machine, and ZJ116 cigarette machine), and it can meet the cutting requirements of tipping paper during cigarette production. Figure 3 As shown, the shearing cutter includes a cylindrical cutter holder and multiple blades. The cylindrical cutter holder can rotate around its axis. All blades are mounted on the cutter holder along its circumference at a preset helix angle. The cutting edge of each blade is inclined away from the cutter holder, and a mounting part is provided on the side of the blade opposite to the cutting edge for connection with the cutter holder. During the rotation of the cutter holder, all blades can sequentially engage with the cutter holder to perform shearing.

[0003] Because blades become dull over time, shearing cutters require periodic disassembly and blade replacement during production. However, during disassembly and assembly, the blades face outwards, making workers susceptible to cuts from the blades, especially on the palms and the area between the thumb and forefinger.

[0004] Therefore, it is necessary to provide a blade removal and installation tool that can prevent workers' hands from being injured. Utility Model Content

[0005] The purpose of this invention is to provide a tool for disassembling and assembling shearing roller blades that can prevent workers' hands from being injured.

[0006] To achieve the above objectives, this utility model provides a shearing reciprocating tool for cutting blades. The tool includes a main frame, a drive mechanism, and a clamping mechanism. The clamping mechanism includes a first clamping plate and a second clamping plate that are parallel to each other. The first and second clamping plates are slidably mounted parallel to each other within the main frame. Each clamping plate has a first clamping portion and a second clamping portion, both located outside the main frame. The drive mechanism can drive the first and second clamping plates to move closer or further apart, so that the first and second clamping portions clamp or release the cutting edge of the blade.

[0007] In some embodiments, the first clamping part and the second clamping part respectively have a protruding block and a clamping groove, the shape of the clamping groove is adapted to the shape of the blade part, and the protruding block can clamp the blade part in the clamping groove.

[0008] In some embodiments, the pressing surface of the protruding block for pressing against the blade portion has a flexible pad layer.

[0009] In some embodiments, the drive mechanism includes a separation mechanism and a clamping mechanism. The separation mechanism enables the first clamping plate and the second clamping plate to move in opposite directions so that the clamping mechanism releases the blade. The clamping mechanism enables the first clamping plate and the second clamping plate to move towards each other so that the protrusion clamps the blade portion in the clamping groove.

[0010] In some embodiments, the separation mechanism includes two springs, which are respectively disposed on both sides of the clamping mechanism along its length. The two ends of the springs are respectively connected to the first clamping plate and the second clamping plate. When the first clamping plate and the second clamping plate move toward each other under the drive of the clamping mechanism until the protrusion clamps the blade portion into the clamping groove, the spring is compressed and embedded in the first clamping plate or the second clamping plate.

[0011] In some embodiments, the clamping mechanism includes a first pressure plate and a second pressure plate. The first pressure plate slides through the main frame and is connected to the first clamping plate. The second pressure plate slides through the main frame and is connected to the second clamping plate. The first pressure plate and the second pressure plate can drive the first clamping plate and the second clamping plate to move toward each other so that the protruding block clamps the blade portion in the clamping groove.

[0012] In some embodiments, the two plates in the length direction of the main frame are respectively provided with slide grooves extending along their width direction. The two slide grooves are arranged in parallel. The two ends of the first clamping plate in the length direction are respectively slidably connected to their corresponding slide grooves by sliders. The two ends of the second clamping plate in the length direction are respectively slidably connected to their corresponding slide grooves by sliders.

[0013] In some embodiments, both plates in the width direction of the main frame are provided with dust removal holes corresponding to the slide groove.

[0014] In some embodiments, a calibration surface is formed on one side of the main frame facing the first clamping portion and the second clamping portion. The calibration surface is used to fit against the first surface of the connecting portion of the hob holder. When the calibration surface fits against the first surface of the connecting portion of the hob holder, the side of the blade can fit against the mounting surface of the hob holder, and the mounting portion of the blade is located at the mounting position of the hob holder.

[0015] In some embodiments, the main frame is a rectangular frame.

[0016] The above-mentioned technical solution of this utility model has the following effects: When assembling or disassembling the blade, the worker places the cutting edge between the first and second clamping parts. The drive mechanism then moves the first and second clamping parts in opposite directions, clamping them onto both sides of the blade. At this point, the cutting edge is fixed between the clamping parts and is not exposed. Therefore, the worker does not directly contact the cutting edge when removing or installing the blade from or onto the cutter holder, effectively reducing the risk of hand injury. After assembly or disassembly, the worker can release the blade by moving the first and second clamping parts in opposite directions using the drive mechanism. Attached Figure Description

[0019] The specific embodiments of this utility model are described in detail below. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0020] In this utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the orientation in the assembled and used state. "Inner" and "outer" refer to the inner and outer sides relative to the outline of each component itself.

[0021] like Figure 1 and Figure 2As shown, this utility model provides a shearing reciprocating tool for cutting blades. The shearing reciprocating tool includes a main frame 1, a drive mechanism 2, and a clamping mechanism 3. The clamping mechanism 3 includes a first clamping plate 31 and a second clamping plate 32 that are parallel to each other. The first clamping plate 31 and the second clamping plate 32 are slidably installed in parallel in the main frame 1. The first clamping plate 31 and the second clamping plate 32 respectively have a first clamping part 311 and a second clamping part 321, and both the first clamping part 311 and the second clamping part 321 are located outside the main frame 1. The drive mechanism 2 can drive the first clamping plate 31 and the second clamping plate 32 to move closer or further away from each other, so that the first clamping part 311 and the second clamping part 321 clamp or release the cutting edge of the blade 4.

[0022] Specifically, when disassembling and assembling the blade 4, the worker can place the cutting edge of the blade 4 between the first clamping part 311 and the second clamping part 321. Then, the drive mechanism 2 causes the first clamping part 311 and the second clamping part 321 to move in opposite directions, clamping the blade 4 on both sides respectively. At this time, the cutting edge of the blade 4 is fixed between the first clamping part 311 and the second clamping part 321 and is in a non-exposed state. Therefore, when the worker removes the blade 4 from the cutter holder 5 or installs the blade 4 onto the cutter holder 5, the cutting edge will not come into direct contact, effectively reducing the risk of hand injury. After the worker has finished disassembling and assembling, the drive mechanism 2 can be used to move the first clamping part 311 and the second clamping part 321 in opposite directions, thereby releasing the blade 4.

[0023] In some embodiments, the main frame 1 is a rectangular tube shape, which includes four side plates, including two parallel and oppositely arranged first side plates. The first clamping plate 31 and the second clamping plate 32 are respectively slidably connected to the inner walls of the two first side plates, and the first clamping plate 31 and the second clamping plate 32 can slide parallel to each other or away from each other.

[0024] In some embodiments of the present invention, the first clamping part 311 and the second clamping part 321 respectively have a protruding block 312 and a clamping groove 322. The shape of the clamping groove 322 is adapted to the shape of the blade part, and the protruding block 312 can clamp the blade part in the clamping groove 322.

[0025] Specifically, when the clamping mechanism 3 clamps the cutting edge, the cutting edge is embedded in the clamping groove 322, and its side facing away from the clamping groove 322 is pressed against by the protruding block 312. The clamping method using the protruding block 312 and the clamping groove 322 effectively improves the stability of the blade 4 clamping and prevents the blade 4 from slipping out during clamping. Furthermore, the clamping groove 322 acts as a limit, defining the area of ​​the clamped blade 4.

[0026] In some embodiments of this utility model, the pressing surface of the protruding block 312 for pressing the blade portion has a flexible pad to effectively protect the blade 4.

[0027] In some embodiments of this utility model, the driving mechanism 2 includes a separation mechanism and a clamping mechanism. The separation mechanism enables the first clamping plate 31 and the second clamping plate 32 to move in opposite directions so that the clamping mechanism 3 releases the blade 4. The clamping mechanism enables the first clamping plate 31 and the second clamping plate 32 to move towards each other so that the protruding block 312 clamps the blade portion in the clamping groove 322.

[0028] In some embodiments of this utility model, the separation mechanism includes two springs 21, which are respectively disposed on both sides of the clamping mechanism 3 along its length. The two ends of the springs 21 are respectively connected to the first clamping plate 31 and the second clamping plate 32. When the first clamping plate 31 and the second clamping plate 32 move toward each other under the drive of the clamping mechanism until the protruding block 312 clamps the blade portion in the clamping groove 322, the springs 21 are compressed and embedded in the first clamping plate 31 or the second clamping plate 32.

[0029] Specifically, the two springs 21 have a natural state that separates the first clamping plate 31 and the second clamping plate 32. When the clamping mechanism drives the first clamping plate 31 and the second clamping plate 32 to move towards each other, the springs 21 are continuously compressed. When the first clamping plate 31 and the second clamping plate 32 clamp the blade 4, the springs 21 are compressed into the first clamping plate 31 or the second clamping plate 32; that is, the first clamping plate 31 or the second clamping plate 32 is provided with slots for hiding the springs 21. When the clamping mechanism stops working, the springs 21 in the compressed state are no longer subjected to compressive force, thereby returning to their natural state and separating the first clamping plate 31 and the second clamping plate 32.

[0030] In some embodiments of this utility model, the clamping mechanism includes a first pressure plate 22 and a second pressure plate. The first pressure plate 22 is slidably inserted through the main frame 1 and connected to the first clamping plate 31. The second pressure plate is slidably inserted through the main frame 1 and connected to the second clamping plate 32. The first pressure plate 22 and the second pressure plate can drive the first clamping plate 31 and the second clamping plate 32 to move towards each other, so that the protruding block 312 clamps the blade portion in the clamping groove 322.

[0031] Specifically, the first pressure plate 22 is connected to the first clamping plate 31 via a sliding rod, and the second pressure plate is connected to the second clamping plate 32 via a sliding rod. The main frame 1 has two openings at corresponding positions, and the two sliding rods pass through these openings and can slide within them. When the worker pushes the first pressure plate 22 and the second pressure plate towards the inside of the main frame 1, the first clamping plate 31 and the second clamping plate 32 move towards each other to clamp the blade 4. When the worker pulls the first pressure plate 22 and the second pressure plate towards the outside of the main frame 1, the distance between the first clamping plate 31 and the second clamping plate 32 gradually increases, thereby releasing the blade 4.

[0032] In some embodiments of this utility model, the two plates of the main frame 1 along the length direction are respectively provided with slide grooves 11 extending along their width direction. The two slide grooves 11 are arranged in parallel. The two ends of the first clamping plate 31 along the length direction are respectively slidably connected to their corresponding slide grooves 11 by sliders 33. The two ends of the second clamping plate 32 along the length direction are respectively slidably connected to their corresponding slide grooves 11 by sliders 33.

[0033] Specifically, the first clamping plate 31 and the second clamping plate 32 are slidably connected to the slide grooves 11 on both sides of their length direction via the slider 33, and the two slide grooves 11 are arranged in parallel so that the first clamping plate 31 and the second clamping plate 32 can move in parallel.

[0034] In some embodiments of this utility model, both plates of the main frame 1 in the width direction are provided with dust removal holes 12 corresponding to the slide groove 11. When tobacco scraps or dust accumulate in the slide groove 11, workers can insert cleaning tools into the slide groove 11 through the dust removal holes 12 for cleaning.

[0035] like Figure 4 As shown, in some embodiments of this utility model, a calibration surface 13 is formed on the side of the main frame 1 facing the first clamping part 311 and the second clamping part 321. The calibration surface 13 is used to fit against the first surface 53 of the connecting part 51 of the hob holder 5. When the calibration surface 13 fits against the first surface 53 of the connecting part 51 of the hob holder 5, the side of the blade 4 can fit against the mounting surface 52 of the hob holder 5, and the mounting part 41 of the blade 4 is located at the mounting position of the hob holder 5.

[0036] Specifically, the main frame 1 is a rectangular tube shape, including four side plates, including two parallel and opposite first side plates, and second and third side plates alternately connected to them. The second and third side plates are also parallel and opposite to each other, together forming a rectangular tube. The first clamping plate 31 and the second clamping plate 32 are slidably connected to the inner walls of the two first side plates, and the first clamping plate 31 and the second clamping plate 32 can slide parallel to each other or away from each other. The plane formed by the width surfaces of the four side plates corresponding to the exposed side of the clamping mechanism 3 is the calibration surface 13. When the calibration surface 13 is in contact with the first surface 53 of the connecting part 51 of the cutter holder 5, the inclination angle of the blade 4 meets its installation angle requirements, and the mounting part 41 of the blade 4 corresponds to the installation position of the cutter holder 5.

[0037] In some embodiments, the openings on the side of the four side plates facing away from the clamping mechanism 3 are provided with protective plates to enhance the protection of the shearing roller blade removal and installation tool.

[0038] In some embodiments, the main frame 1 is a rectangular frame.

[0039] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0040] It should also be noted that the various specific technical features described in the above embodiments can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0041] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
