Abstract
Description
Technical Field
[0001] This utility model relates to the field of hobbing cutter blade adjustment technology, specifically to a compression hobbing cutter blade adjustment mechanism and a compression hobbing cutter assembly. Background Technology
[0002] The extrusion cutter is an important component of the cigarette tipping paper cutting tool. It consists of a cutting wheel and multiple detachable blades evenly distributed along its circumference. This extrusion cutter can rotate in conjunction with the cutting wheel to continuously cut the tipping paper.
[0003] Because the cutting precision required for cork paper is high, all blade edges need to be aligned to the same circumferential surface when installing the blades. This adjustment is achieved by raising and lowering the blades radially along the roller. Specifically, the blade is placed in the groove of the roller, where an adjusting block is threaded into the center. This adjusting block supports the blade, and its height can be finely adjusted by rotating it, thus allowing for blade height adjustment.
[0004] However, when workers adjust the height, they need to insert the handle directly into the gap between adjacent blades to turn the adjusting block. During this process, workers are easily cut by the upward-facing blade edges. Therefore, to avoid worker injuries, it is necessary to propose a blade adjustment mechanism. Utility Model Content
[0005] The purpose of this invention is to provide a mechanism for adjusting the height of extrusion cutter blades, which can prevent workers from being cut.
[0006] To achieve the above objectives, this utility model provides a compression-type hob blade adjustment mechanism. This mechanism includes a main adjusting rod, a connecting cylinder, and multiple sets of insertion holes. The bottom end of the main adjusting rod is detachably connected to the top of the connecting cylinder, and the top end of the main adjusting rod has a handle. The bottom of the connecting cylinder has two centrally symmetrically distributed insertion posts, with a clearance space between the two insertion posts. The multiple sets of insertion holes correspond one-to-one with multiple adjusting blocks of the compression-type hob. Each set of insertion holes includes multiple pairs of insertion holes, which are disposed on corresponding adjusting blocks. Two insertion posts can be detachably inserted into one pair of insertion holes on the adjusting block. When an insertion post is inserted into one pair of insertion holes on the adjusting block, the blade corresponding to the adjusting block is located in the clearance space, and the insertion post and the connecting cylinder are spaced apart from the blade.
[0007] In some embodiments, the bottom end of the main adjusting rod has an anti-loosening structure, the top of the connecting cylinder is provided with a connecting block, the connecting block has a groove that can fit into the anti-loosening structure, the connecting block has a threaded through hole that connects the cavity of the connecting cylinder and the groove, the bottom of the anti-loosening structure is provided with a threaded blind hole that matches the threaded through hole, and the first bolt can pass through the threaded through hole and the threaded blind hole sequentially from the bottom end of the connecting cylinder to connect the connecting cylinder and the main adjusting rod.
[0008] In some embodiments, the anti-loosening structure is a cutting part located at the bottom end of the main adjusting rod. The cutting part has two symmetrically distributed arc surfaces and two symmetrically distributed planes, and the arc surfaces and planes are alternately distributed. The bottom of the cutting part is provided with a threaded blind hole. The two arc surfaces and two planes surround the threaded blind hole. The cutting part can be embedded in the groove and connected to the connecting cylinder by the first bolt. The arc surfaces and planes respectively fit against the side wall of the groove.
[0009] In some embodiments, an anti-slip washer is provided between the head of the first bolt and the connecting block.
[0010] In some embodiments, the insert includes a reinforcing section and a plug-in section, the top end of the reinforcing section being connected to the bottom of the connecting cylinder, the bottom end of the reinforcing section being connected to the plug-in section, and the plug-in section being detachably insertable into the socket.
[0011] In some embodiments, the reinforcing segment is a polygonal cylinder.
[0012] In some embodiments, the handle is a crossbar vertically connected to the main adjustment rod.
[0013] In some embodiments, the handheld part is provided with a first screw hole, the top end of the main adjusting rod is provided with a second screw hole and a through hole, the handheld part can be inserted vertically into the main adjusting rod through the through hole and the first screw hole and the second screw hole are aligned, and the second bolt is threadedly installed in the first screw hole and the second screw hole.
[0014] In some embodiments, the first screw hole is located at the middle of the handle in its length direction.
[0015] Another aspect of this utility model provides a compression hobbing cutter assembly, which includes a hobbing cutter body and a compression hobbing cutter blade adjustment mechanism as described in the above embodiment. When the insert of the compression hobbing cutter blade adjustment mechanism is inserted into any pair of holes of one of the adjustment blocks of the hobbing cutter body, the compression hobbing cutter blade adjustment mechanism can adjust the height of the blade corresponding to the adjustment block by rotation. When the insert is pulled out of the hole, the hobbing cutter body can operate independently.
[0016] The above-mentioned technical solution of this utility model has the following beneficial effects:
[0017] Each blade has an adjusting block underneath to support its height. This adjusting block has multiple pairs of insertion holes, each pair being centrally symmetrically distributed with the same center of symmetry. The adjusting block is threaded to the hobbing wheel and its top surface can be rotated to adjust the height of the hobbing wheel, thus adjusting the blade's cutting edge height. In any rotational position, at least one pair of insertion holes is located on both sides of the corresponding blade, and two posts can be detachably inserted into the pair of insertion holes on both sides of the blade. When adjusting the blade height, the two posts of the compression-type hobbing blade adjusting mechanism are inserted into the two insertion holes on both sides of the blade. The worker can hold the handle and rotate the posts clockwise or counterclockwise to raise or lower the adjusting block, thereby adjusting the blade height. This invention's compression-type hobbing blade adjusting mechanism, by connecting the posts to the main adjusting rod, allows the worker's arms and body to stay away from the blade when rotating the adjusting block, effectively preventing the worker from being cut by the blade.

[0024] 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.

[0026] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the utility model described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0027] like Figure 1 As shown, this utility model provides a compression-type hob blade adjustment mechanism, which includes a main adjusting rod 1, a connecting cylinder 2, and multiple sets of insertion holes. The bottom end of the main adjusting rod 1 can be detachably connected to the top of the connecting cylinder 2, and the top end of the main adjusting rod 1 is provided with a hand-held part. The bottom of the connecting cylinder 2 is provided with two centrally symmetrically distributed insertion posts 3, and a clearance space is formed between the two insertion posts 3. The multiple sets of insertion holes correspond one-to-one with multiple adjusting blocks 8 of the compression-type hob. The insertion hole sets include multiple pairs of insertion holes 9, which are set on the corresponding adjusting blocks 8. The two insertion posts 3 can be detachably inserted into one pair of insertion holes 9 on the adjusting block 8. When the insertion post 3 is inserted into one pair of insertion holes 9 on the adjusting block 8, the blade corresponding to the adjusting block 8 is located in the clearance space, and the insertion post 3 and the connecting cylinder 2 are spaced apart from the blade.
[0028] Specifically, each blade has an adjusting block 8 underneath to support its height. This adjusting block 8 has multiple pairs of insertion holes 9, each pair of holes 9 being centrally symmetrically distributed with the same center of symmetry. The adjusting block 8 is threadedly connected to the hobbing wheel and its top surface can be rotated to adjust the height of the hobbing wheel, thereby adjusting the blade's cutting edge height. Furthermore, in any rotational position, at least one pair of insertion holes 9 is located on both sides of the corresponding blade, and two insertion posts 3 can be detachably inserted into the pair of insertion holes 9 on both sides of the blade. When adjusting the blade height, the two insertion posts 3 of the compression-type hobbing blade adjusting mechanism are inserted into the two insertion holes 9 on both sides of the blade. The worker can hold the handle and rotate the insertion posts 3 clockwise or counterclockwise to raise or lower the adjusting block 8, thus adjusting the blade height. The extrusion-type roller cutter blade adjustment mechanism of this utility model connects the insert 3 to the main adjustment rod 1, so that when the worker rotates the adjustment block 8, his arm and body can be kept away from the blade, thereby effectively preventing the worker from being cut by the blade.
[0029] like Figure 2 and Figure 3As shown, in some embodiments of this utility model, the bottom end of the main adjusting rod 1 has an anti-loosening structure, the top of the connecting cylinder 2 is provided with a connecting block 4, the connecting block 4 has a groove 43 that can fit into the anti-loosening structure, the connecting block 4 has a threaded through hole that connects the cavity of the connecting cylinder 2 and the groove 43, the bottom of the anti-loosening structure is provided with a threaded blind hole 11 that matches the threaded through hole, and the first bolt 41 can pass through the threaded through hole and the threaded blind hole 11 sequentially from the bottom end of the connecting cylinder 2 so as to connect the connecting cylinder 2 and the main adjusting rod 1.
[0030] Specifically, the main adjusting rod 1 and the connecting cylinder 2 are connected by a threaded connection, which enhances the replaceability of the connecting cylinder 2, allowing for quick replacement and cost savings when the insert 3 is damaged. The bottom end of the main adjusting rod 1 has an anti-loosening structure for engaging with the groove 43. When the main adjusting rod 1 rotates, the mechanical interlock between the anti-loosening structure and the groove 43 prevents the first bolt 41 from rotating, thus avoiding accidental loosening of the first bolt 41. The installation process of the main adjusting rod 1 and the connecting cylinder 2 is as follows: First, the anti-loosening structure at the bottom end of the main adjusting rod 1 is embedded into the groove 43. Then, the first bolt 41 is inserted upwards into the cavity of the connecting cylinder 2 from the opening at the bottom end, and the first bolt 41 is screwed into the threaded through hole on the connecting block 4. The first bolt 41 is further rotated to make it threadedly connected with the threaded blind hole 11 of the anti-loosening structure until the head of the first bolt 41 presses against the bottom surface of the connecting block 4 facing the connecting cylinder 2. Finally, the main adjusting rod 1, the connecting block 4, and the connecting cylinder 2 are securely locked together by the first bolt 41.
[0031] like Figure 4 As shown, in some embodiments of this utility model, the anti-loosening structure is a cutting part 7 located at the bottom end of the main adjusting rod 1. The cutting part 7 has two symmetrically distributed arc surfaces and two symmetrically distributed planes, and the arc surfaces and planes are alternately connected. The bottom of the cutting part 7 is provided with a threaded blind hole 11. The two arc surfaces and two planes surround the threaded blind hole 11. The cutting part 7 can be embedded in the groove 43 and connected to the connecting cylinder 2 by the first bolt 41. The arc surfaces and planes are respectively in contact with the side wall of the groove 43.
[0032] Specifically, the two symmetrically distributed arc surfaces and two symmetrically distributed blocking surfaces of the cutting part 7 are alternately connected to form a fitting structure. This fitting structure allows the cutting part 7 to be tightly embedded in the groove 43, thereby enhancing the connection stability between the main adjusting rod 1 and the connecting cylinder 2.
[0033] In some embodiments of this utility model, an anti-slip washer 42 is provided between the head of the first bolt 41 and the connecting block 4 to make the connection between the main adjusting rod 1 and the connecting cylinder 2 more secure.
[0034] In some embodiments of this utility model, the insert 3 includes a reinforcing section 31 and a plug-in section 32. The top end of the reinforcing section 31 is connected to the bottom of the connecting cylinder 2, and the bottom end of the reinforcing section 31 is connected to the plug-in section 32. The plug-in section 32 can be detachably inserted into the socket 9.
[0035] Specifically, the reinforcing section 31 can increase the overall stress strength of the insert post 3 and improve the durability of the extrusion-type hob blade adjustment mechanism.
[0036] In some embodiments of this utility model, in order to improve the torsional resistance of the insert 3, the reinforcing section 31 is a polygonal column.
[0037] In some embodiments of this utility model, to facilitate workers to grasp and rotate, the hand-held part is a horizontal bar 5 vertically connected to the main adjusting rod 1.
[0038] like Figure 4 As shown, in some embodiments of this utility model, the handheld part is provided with a first screw hole, the top end of the main adjusting rod 1 has a second screw hole and a through hole 12, the handheld part can be vertically inserted into the main adjusting rod 1 through the through hole 12 and the first screw hole and the second screw hole are aligned, and the second bolt 6 is threadedly installed in the first screw hole and the second screw hole.
[0039] In some embodiments of this utility model, the first screw hole is located at the middle of the hand-held part in its length direction.
[0040] In another aspect, this utility model provides a compression hobbing cutter assembly, which includes a hobbing cutter body and a compression hobbing cutter blade adjustment mechanism as described in the above embodiment. When the insert 3 of the compression hobbing cutter blade adjustment mechanism is inserted into any pair of insertion holes 9 of one of the adjustment blocks of the hobbing cutter body, the compression hobbing cutter blade adjustment mechanism can adjust the height of the blade corresponding to the adjustment block by rotation. When the insert 3 is pulled out of the insertion hole 9, the hobbing cutter body can operate independently.
[0041] 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.
[0042] 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.
[0043] 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.
