A positioning device for embossing roller assembly

Abstract

This application discloses a positioning device for embossing roller assemblies, comprising a base frame, a front support, and a rear support. Both the front and rear supports are located on the top surface of the base frame. The top surfaces of both the front and rear supports are arc-shaped. The front support has mounting holes on its side. When assembling the embossing roller assembly, one end of the sleeve of the embossing roller assembly is fitted and fixed to the front support, and is limited by the mounting holes to prevent wobbling. The rear support has a fixing block on its side. When assembling the embossing roller assembly, the flange is secured by the fixing block. This ensures that one end of the flange of the embossing roller assembly is fitted and fixed to the rear support. During assembly and disassembly of the embossing roller assembly, the fixing block restricts the rotational freedom of the flange and provides a reverse torque during assembly. This embossing roller assembly positioning device can shorten operation time and reduce workload.

Description

Technical Field

[0001] This application relates to the field of packaging machine parts assembly technology, specifically to a positioning device for an embossing roller assembly. Background Technology

[0002] Existing packaging machines include an embossing roller assembly and a symmetrical roller assembly. The embossing roller assembly is mounted on a bracket by screws, and the symmetrical roller assembly is mounted on a guide shaft by screws. During operation, the guide shaft moves within the holes of the bracket under the action of a cylinder, causing the symmetrical rollers to contact the embossing rollers and maintain a certain pressure, rotating in opposite directions to complete the embossing of the inner lining paper.

[0003] The embossed patterns on the inner lining paper of different cigarette products vary, and the embossing roller assembly will wear out during use. When producing different embossed patterns for the inner lining paper or when the assembly wears out, the embossing roller assembly must be replaced. Replacing the embossing roller assembly requires removing the screws, taking the assembly out of its support, and disassembling it for replacement.

[0004] The structure of the embossing roller assembly is as shown in the attached instruction manual. Figure 1 As shown: The needle roller bearing is installed in the right cavity of the sleeve; the flange assembly is screwed into the left cavity of the sleeve and secured by a lock nut; the rolling bearing embedded in the inner hole of the flange assembly mates with the left cylindrical surface of the embossing roller, and the embossing roller forms a rotating connection structure with the sleeve through the aforementioned three bearings; the pressure cap is installed in the left hole of the flange assembly by four screws to axially position the rolling bearing embedded in the flange assembly; the round nut is threaded to the left side of the embossing roller to axially lock the embossing roller and the flange; by loosening the lock nut and rotating the flange, the axial position of the embossing roller can be adjusted. The limit screw is installed in the threaded hole of the sleeve, and its head is embedded in the annular groove on the embossing roller. This limits the range of axial adjustment of the embossing roller and prevents mechanical failure due to excessive axial adjustment. The marking disc is fixed to the embossing roller on the left side of the flange seat by the set screw. It serves to mark the starting position of the spare inner lining paper during operation. The one-way bearing in the sleeve assembly is connected to the embossing roller by a key and is axially positioned by an elastic retaining ring. The handle is fixedly connected to the sleeve assembly by three screws. Under the action of the one-way bearing, the embossing roller rotates when the handle is turned in the direction of the inner lining paper advance, and does not move when rotated in the opposite direction.

[0005] The structure of the sleeve can be found in the instruction manual. Figure 2 and attached Figure 3 It is fitted with the inner hole of the bracket through the first cylindrical surface and the second cylindrical surface, and is installed on the bracket by screws through the countersunk hole. The first end face is in close contact with the corresponding surface on the bracket; the countersunk hole on the other end face is used to install the limit screw.

[0006] The structure of the flange can be found in the attached instruction manual. Figure 4 and attached Figure 5 The inner hole of the conical surface is provided with a keyway, which is connected to the conical cylindrical surface of the right end of the embossing roller by a key, and is axially fastened by screws and washers through the boss end face 123. The rectangular slot on the circumference of the flange is connected to the rectangular protrusion on the main drive shaft, which acts as a jaw clutch to transmit the power of the main drive shaft to the embossing roller assembly to complete the embossing action of the inner lining paper. The flange is also provided with 3 threaded holes for disassembling the flange.

[0007] In existing technology, when disassembling the embossing roller assembly, the assembly is first removed from the bracket; three screws are removed, and the handle is taken off; the elastic retaining ring is removed, and the sleeve assembly and key are removed; the set screw is loosened, and the marking plate is removed; four screws are removed, and the pressure cap is removed; the round nut is removed, the lock nut is loosened, and the flange assembly is rotated off; the screws and washers are removed, and spare screws are screwed into the threaded holes of the flange, using the end face of the sleeve to push the flange out and remove it; the key is removed, and the embossing roller is taken out of the sleeve. Assembly is the reverse of the above sequence, and will not be described in detail here.

[0008] However, in practice, the above disassembly and assembly must be performed on a bench vise. When loosening the round nuts, locking nuts, and screws, the outer cylindrical surface of the flange needs to be clamped above the bench vise for operation. The total weight of the component is 12 kg, requiring multiple people to complete the disassembly and assembly work, which is labor-intensive.

[0009] Meanwhile, because the outer cylindrical surface of the flange and the bench vise have a line contact of 8mm on each side, it is difficult to clamp them tightly. As a result, the torque between the outer cylindrical surface of the flange and the jaws of the bench vise is insufficient to loosen the corresponding fasteners, causing relative slippage and damage to the outer cylindrical surface of the flange.

[0010] In addition, the components are unstable after being clamped in the bench vise, and clamping failure is prone to occur during disassembly and assembly, which may lead to safety accidents.

[0011] Therefore, how to provide a positioning auxiliary device for stable positioning when disassembling and assembling embossing roller assemblies is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0012] The purpose of this application is to provide a positioning device for embossing roller assembly that can stably position the assembly during disassembly and assembly.

[0013] To achieve the above objectives, this application provides a embossing roller assembly positioning device for placing embossing roller assemblies, including: a base frame, a front support, and a rear support; both the front support and the rear support are disposed on the top surface of the base frame, and the top surfaces of both the front support and the rear support are configured as arc surfaces;

[0014] The side of the front support is provided with an assembly hole, which is used to limit the sleeve of the embossing roller assembly.

[0015] A fixing block is provided on the side of the rear support. The fixing block is used to snap and fix the flange of the embossing roller assembly to the top surface of the rear support.

[0016] In some embodiments, the top surface of the base frame is detachably fitted with a first mounting screw and a second mounting screw.

[0017] The first mounting screw is used to pass through the sleeve and connect to the mounting hole;

[0023] In some embodiments, the base frame further includes: an auxiliary support mechanism, which includes a snap-fit ​​assembly extending to both sides of the connecting plate and a support arm assembly rotatably connected to both ends of the top surface of the first strip plate;

[0024] The support arm assembly and the snap-fit ​​assembly located on the same side of the connecting plate can be snapped together.

[0025] In some embodiments, the snap-fit ​​assembly includes: a snap-fit ​​bracket mounted on the bottom surface of the base frame and snap-fits disposed on both sides of the snap-fit ​​bracket.

[0026] In some embodiments, the support arm assembly includes: a limiting block, a connecting rod, and an auxiliary adjustment support base;

[0027] The limiting block is installed on the top surface of the first strip plate, the first end of the connecting rod is hinged in the limiting block, and the auxiliary adjustment support is installed on the second end of the connecting rod. The connecting rod can rotate horizontally relative to the limiting block so that the auxiliary adjustment support is engaged in the corresponding buckle.

[0028] In some embodiments, both the adjusting support and the auxiliary adjusting support include a locking nut, an adjusting screw, and a support foot connected sequentially from top to bottom.

[0029] In some embodiments, a locking device is provided inside the limiting block to restrict the rotation of the connecting rod.

[0030] In some embodiments, the base frame has weight-reducing perforations.

[0031] Compared to the aforementioned background technology, this application includes a base frame, a front support, and a rear support; both the front and rear supports are located on the top surface of the base frame.

Detailed Implementation

[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] Reference manual attached Figure 6 and attached Figure 7 , Figure 6 This is an assembly diagram of the embossing roller assembly and the embossing roller assembly positioning device provided in the embodiments of this application. Figure 7 for Figure 6A schematic diagram of the assembly from another perspective shows an embossing roller assembly positioning device for placing the embossing roller assembly 1, including: a base frame 2, a front support 3, and a rear support 4; both the front support 3 and the rear support 4 are located on the top surface of the base frame 2. The top surfaces of both the front support 3 and the rear support 4 are arc-shaped. The side of the front support 3 has an assembly hole. When assembling the embossing roller assembly 1, the countersunk hole 111 of the sleeve 11 is aligned with the assembly hole, and then the two are positioned using mounting parts. The radius of the arc surface of the front support 3 is consistent with the radius of the first cylindrical surface 112 where the sleeve 11 is located, ensuring that one end of the embossing roller assembly 1 with the sleeve 11 is fitted and fixed to the front support 3, and is positioned by the assembly hole to prevent wobbling.

[0049] The rear support 4 is fitted with a fixing block 41 on its side. When assembling the embossing roller assembly 1, the rectangular slot 121 of the flange 12 is rotated to correspond with the fixing block 41, and the flange 12 is snapped and fixed by the fixing block 41. The radius of the arc surface of the rear support 4 is consistent with the radius of the second cylindrical surface 113 where the flange 12 is located, ensuring that the end of the embossing roller assembly 1 with the flange 12 is fitted and fixed on the rear support 4. When disassembling and assembling the embossing roller assembly 1, the fixing block 41 can restrict the degree of freedom of rotation of the flange 12 and provide a reverse torque during assembly.

[0050] The embossing roller assembly positioning device of this application can shorten the operation time and reduce the workload; at the same time, it will not cause equipment damage when disassembling the embossing roller assembly 1.

[0051] Further, refer to the attached instruction manual. Figure 8 , Figure 8 The schematic diagram of the embossing roller assembly positioning device provided in this application embodiment includes: a first mounting screw 21 and a second mounting screw 22 are detachably provided on the top surface of the base frame 2; the first mounting screw 21 is used to pass through the countersunk hole 111 of the sleeve 11 into the mounting hole to achieve connection limiting; the second mounting screw 22 is used to pass through the threaded hole 122 to disassemble the flange 12. This ensures that the positioning device itself carries a set of spare screws as disassembly and positioning parts, assisting in the integration of positioning and disassembly functions.

[0052] Further, refer to the attached instruction manual. Figure 9 , Figure 9The exploded view of the embossing roller assembly positioning device provided in the embodiment of this application includes: the base frame 2 is configured as an I-shaped base frame, the I-shaped base frame includes: a connecting plate 23, the two ends of the connecting plate 23 are respectively connected to a first strip plate 24 and a second strip plate 25, and the first strip plate 24 and the second strip plate 25 are arranged parallel to each other; a first groove is opened on the top surface of the first strip plate 24, the front support 3 is installed in the first groove by a positioning pin that cooperates with the threaded hole in the first groove through screws, the top surface of the second strip plate 25 is opened with a second groove, and the rear support 4 is installed in the second groove by a positioning pin that cooperates with the threaded hole in the second groove through screws.

[0053] Furthermore, at least two adjusting support seats 5 are provided on the side of the first strip plate 24 away from the second strip plate 25; at least two adjusting support seats 5 are provided on the side of the second strip plate 25 away from the first strip plate 24; at least four adjusting support seats 5 form a stable support below the base frame 2.

[0054] Further, refer to the attached instruction manual. Figure 10 and attached Figure 11 , Figure 10 This is an assembly diagram of the embossing roller assembly positioning device provided in the embodiments of this application. Figure 11 This is a schematic diagram of the embossing roller assembly positioning device provided in this application embodiment with the support arm retracted. The base frame 2 further includes an auxiliary support mechanism, which includes a snap-fit ​​assembly and a support arm assembly. The snap-fit ​​assembly extends to both sides of the connecting plate 23, and the support arm assembly is rotatably connected to both ends of the top surface of the first strip plate 24. The support arm assembly and the snap-fit ​​assembly located on the same side of the connecting plate 23 can be correspondingly snapped together.

[0055] When the embossing roller assembly 1 is not installed, the support arm assembly is snapped into the buckle assembly and is in a retracted state. After the embossing roller assembly 1 is installed, the torsional force generated during disassembly of the embossing roller assembly 1 will cause the base frame 2 to be unstable. At this time, it is necessary to unfold the support arm assemblies on both sides as additional support points to provide support force and ensure the stability of the equipment.

[0056] It is foreseeable that the support arm assembly can also be set in other positions on the base frame 2, as long as its supporting effect is guaranteed. The aforementioned buckle assembly can be adaptively adjusted according to the installation position of the support arm assembly. However, based on the force principle analysis when disassembling and assembling the embossing roller assembly 1, the supporting effect installed on the surface of the first strip plate 24 is good, so it is selected in this embodiment.

[0057] The aforementioned latching assembly includes a latching bracket 61 mounted on the bottom surface of the base frame 2 and latches 62 disposed on both sides of the latching bracket 61.

[0058] Furthermore, the aforementioned support arm assembly includes: a limiting block 71, a connecting rod 72, and an auxiliary adjustment support seat 73. The limiting blocks 71 are respectively installed at both ends of the top surface of the first strip plate 24. Both limiting blocks 71 have slots. The first end of the connecting rod 72 is hinged within the slot of the limiting block 71. A vertically arranged pin 74 passes through the limiting block 71 and the first end of the connecting rod 72, achieving a rotatable connection. The top of the limiting block 71 is assembled using a handle screw 75. The auxiliary adjustment support seat 73 is installed at the second end of the connecting rod 72. After rotation, the corresponding auxiliary adjustment support seat 73 can be engaged in the buckle 62.

[0059] In one embodiment of this application: a spacer is provided between the base frame 2 and the support arm assembly, and the connecting rod 72 rotates in a direction parallel to the base frame 2 with the pin 74 as the rotation axis to realize the movement of the auxiliary adjustment support 73.

[0060] It is foreseeable that the hinge structure between the connecting rod 72 and the limiting block 71 can be set with reference to existing technology, and will not be elaborated here.

[0061] Furthermore, both the aforementioned adjusting support 5 and auxiliary adjusting support 73 include, from top to bottom, a locking nut 51, an adjusting screw 52, ​​and a support foot 53 connected sequentially. Height adjustment is achieved by twisting the adjusting screw 52. Conventional connecting components such as washers and elastic retaining rings are sandwiched between the structures. It is foreseeable that the structure of the support is not limited to the above, and its installation method can refer to existing technologies, which will not be elaborated upon here.

[0062] Furthermore, a locking device is provided inside the aforementioned limiting block 71. The locking device includes, but is not limited to, locking by means of a pin shaft, which will not be elaborated here.

[0063] Furthermore, the aforementioned base frame 2 is provided with weight-reducing perforated holes to facilitate the movement and handling of the entire equipment.

[0064] Taking the disassembly of the embossing roller assembly 1 as an example, the application of this invention is illustrated as follows: The embossing roller assembly 1 is installed on this positioning device. During installation, ensure that the rectangular slot 121 on the flange 12 is engaged with the fixing block 41, the inner arc surface of the front support 3 is in contact with the first cylindrical surface 112 of the sleeve 11, the inner arc surface of the rear support 4 is in contact with the second cylindrical surface 113 of the sleeve 11, and the first end face of the sleeve 11 is in contact with the end face of the front support 3. The embossing roller assembly 1 is then fixed to this device using two first mounting screws 21. Then, the embossing roller assembly 1 is disassembled in sequence. When disassembling the flange 12, it can be pushed out in the opposite direction using three second mounting screws 22.

[0065] The device of this invention eliminates the need for a bench vise during the disassembly and assembly of the embossing roller assembly 1, solving the positioning difficulties in this process and allowing for operation by a single person. It also eliminates the problem of damage to the outer cylindrical surface of the flange caused by bench vise clamping and avoids safety issues caused by bench vise clamping failure. This device is easy to move and use.

[0066] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0067] The positioning of the embossing roller assembly provided in this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
