Description

Technical Field

[0001] The present invention relates to the technical field of tobacco production equipment, in particular to a groove plate structure of a slitting hub wheel and the slitting hub wheel. Background Art

[0002] Filter rods are one of the important raw materials in the cigarette industry. During the production process of filter rods, it is usually necessary to cut the filter rods, cutting a double-length (or multiple-length) filter rod into two (or more) filter rods.

[0003] In the existing technology, a slitting hub wheel is usually used in conjunction with a cutter to achieve slitting of filter rods. The slitting hub wheel adsorbs double-length (or multiple-length) filter rods in the filter rod groove on the outer periphery of the slitting hub wheel through negative pressure adsorption. The slitting hub wheel rotates, thereby driving the double-length (or multiple-length) filter rods to the position of the cutter, and then the cutter cuts the double-length (or multiple-length) filter rods on the slitting drum wheel to form multiple relatively short filter rods.

[0004] However, in the prior art, filter rods have a variety of different diameter specifications, and a slitting hub wheel can only be adapted for use with filter rods of one diameter specification, resulting in the need to use different slitting equipment when producing filter rods of different diameter specifications.

[0005] In addition, in the prior art, there is also a structure that can replace the bearing shells on the periphery of the slitting hub wheel. The filter rod grooves for accommodating filter rods are provided on the bearing shells on the periphery of the slitting hub wheel, and the bearing shells are provided in a variety of specifications. The size of the filter rod grooves on the bearing shells of one specification is designed for filter rods of one diameter specification. When the production specification of the filter rods needs to be changed, the equipment is shut down and the bearing shells on the slitting hub wheel are replaced, so that the slitting hub wheel can be adapted to filter rods of another diameter specification for use. However, in the prior art, when replacing specification parts such as bearing shells, a large number of structural parts need to be disassembled, the replacement cycle is long, the equipment downtime is long, and the operator's skills are required to be high. Summary of the Invention

[0006] In view of the technical problems that arise in the prior art, when changing the production specifications of filter rods, the bearings need to be replaced, and the replacement cycle is long, resulting in a long equipment downtime, affecting production efficiency. In addition, the replacement of the bearings requires high skills from the operator, and the replacement is difficult. The present invention provides a slot plate structure for a slitting hub wheel, which is provided with a fixed part and a movable part. The outer periphery of the fixed part is provided with a plurality of first sheets, and the movable part is provided with a second sheet. The second sheet is inserted between the two first sheets, and the edge of the second sheet and the edge of the first sheet together form a filter rod slot, and the movable part has multiple installation positions in the circumferential direction. When producing filter rods of different diameters, it is only necessary to rotate and adjust the position of the movable part, so that the slot width of the filter rod slot can be adjusted accordingly to adapt to the production of filter rods of different diameters. During the conversion process, there is no need to disassemble a large number of structural parts, thereby reducing the long equipment downtime and improving production efficiency. The operation is simple, and the skill requirements for the operator are reduced.

[0043] The present invention provides a slot plate structure for a slitting hub wheel, comprising a slot plate and a filter rod slot and a cutting knife slot provided on the outer periphery of the slot plate; the slot plate comprises a fixed part and a movable part mounted on the fixed part; a plurality of first sheets are sequentially spaced apart on the outer periphery of the fixed part; a plurality of second sheets are provided on the movable part; a second sheet is provided between each two adjacent first sheets, and the second sheets are spaced apart from the first sheets to form the filter rod slot; the movable part has a plurality of mounting positions on the fixed part along the circumference of the slot plate. In the slot plate structure for the slitting hub wheel, the filter rod slot is formed by the first sheets and the second sheets being spaced apart from each other, and the movable part has a plurality of mounting positions on the fixed part along the circumference of the slot plate, so that the spacing between the first sheets and the second sheets can be adjusted by adjusting the mounting position of the movable part on the fixed part along the circumference, thereby adjusting the slot width of the filter rod slot. When changing the production specifications of the filter rod, it is only necessary to adjust the installation position of the movable part to adaptively adjust the filter rod slot to a suitable slot width to adapt to the production of filter rods with different diameters. During the conversion process, there is no need to disassemble a large number of structural parts, thereby reducing the equipment downtime and improving production efficiency. In addition, the operation is simple and the skill requirements for the operator are reduced.

[0044] Please refer to Figures 1 to 3 In one embodiment, a slotted plate structure 100 for a slitting hub wheel is provided. The width of the filter rod slots provided therein can be adaptively adjusted, thereby accommodating filter rods of varying diameters. The slotted plate structure 100 for a slitting hub wheel is primarily designed to address the prior art problem of requiring the disassembly and assembly of numerous components when changing production specifications, resulting in long replacement cycles and prolonged equipment downtime, thus impacting production efficiency.

[0045] The slotted plate structure 100 of the slitting hub wheel comprises a slotted plate 10, a filter rod slot 20, and a cutter slot 30 defined on the outer periphery of the slotted plate 10. The slotted plate 10 comprises a fixed member 11 and a movable member 12 mounted on the fixed member 11. Multiple first plates 111 are sequentially spaced apart on the outer periphery of the fixed member 11, and multiple second plates 121 are mounted on the movable member 12. A second plate 121 is positioned between every two adjacent first plates 111. Specifically, a second plate 121 is inserted into the area between two adjacent first plates 111, and a second plate 121 is inserted into the area between every two adjacent first plates 111. Thus, along the circumference of the slotted plate 10, the plates are arranged in the following order: first plate 111, second plate 121, first plate 111, second plate 121, and so on. The second plates 121 are spaced apart from the first plates 111 to form the filter rod slot 30. That is to say, the filter rod slot 30 is opened between the first sheet 111 and the second sheet 121, and the circumferential edge of the second sheet 121 and the circumferential edge of the first sheet 111 constitute a part of the filter rod slot 30, so that by adjusting the spacing distance between the second sheet 121 and the first sheet 111, the slot width of the filter rod slot 30 can be adjusted accordingly.

[0046] Along the circumference of the slot plate 10, the movable part 12 has a plurality of mounting positions on the fixed part 11. That is to say, there is not only one mounting position between the movable part 12 and the fixed part 11, but a plurality of mounting positions along the circumference. The relative position of the movable part 12 and the fixed part 11 can be adjusted by rotating the movable part 12 relative to the fixed part 11, and after the relative position is adjusted, the movable part 12 can still be installed and fixed on the fixed part 11. Since the second sheet 121 is provided on the movable part 12, after adjusting the position of the movable part 12, the spacing distance between the second sheet 121 and the first sheet 111 can be adjusted synchronously, thereby correspondingly adjusting the slot width of the filter rod slot 30, so that the slot plate structure 100 of the slitting hub wheel can be adapted to the production of filter rods of different diameters.

[0047] It is understandable that filter rods currently have many different specifications. For commonly produced filter rods, there are currently roughly 19 types of rod material numbers. The specific parameters are shown in Table 1 below.

[0048] Table 1 Filter rod cutting parameters

[0049]

[0050] Currently, conventional filter rods have four diameter specifications. In the existing technology, each diameter specification of filter rods usually has a corresponding specification of bearing. When producing filter rods with different diameter specifications, it is necessary to replace the bearing on the periphery of the slitting hub wheel. The bearing corresponding to the required filter rod diameter must be installed on the periphery of the slitting hub wheel to achieve the slitting production of filter rods. However, when replacing the bearing and other specifications, a large number of structural parts need to be disassembled, the replacement cycle is long, the equipment downtime is long, and the operator's skills are required to be high.

[0051] In the slot plate structure 100 of the slitting hub wheel provided in this embodiment, the filter rod slot 20 is formed by the second sheet 121 on the movable part 12 and the first sheet 111 on the fixed part 11. When the production specifications need to be changed, it is only necessary to adjust the installation position of the movable part 12 on the fixed part 11 to adjust the slot width of the filter rod slot 20 to the required width, so that filter rods of different diameters can be adapted for production. For example, when it is necessary to change the production of filter rods with large diameters, the second sheet 121 can be adjusted away from the first sheet 111, so that the slot width of the filter rod slot 20 can be increased to adapt to the production of filter rods with large diameters; and when it is necessary to change the production of filter rods with small diameters, the second sheet 121 can be adjusted toward the first sheet 111, so that the slot width of the filter rod slot 20 can be reduced to adapt to the production of filter rods with small diameters. When changing the production specifications, the slot plate structure 100 of the slitting hub wheel does not require overall replacement of components, nor does it require disassembly of a large number of structural parts. It only requires rotating and adjusting the position of the movable part 12, so that the slot width of the filter rod slot 20 can be adjusted accordingly to adapt to the production of filter rods of different diameters. This can reduce equipment downtime, improve production efficiency, and is simple to operate, reducing the skill requirements for operators.

[0052] Preferably, in one embodiment, the first sheets 111 on the outer circumference of the fixing member 11 are evenly spaced apart. That is, on the fixing member 11, the spacing between each two adjacent first sheets 111 is equal, so that the first sheets 111 arranged on the fixing member 11 are evenly spaced apart as a whole. The movable member 12 includes a mounting portion 122 and a second sheet 121. The mounting portion 122 is mounted on the fixing member 11, and the second sheet 121 is arranged on the mounting portion 122. Along the circumference of the slot plate 10, the second sheets 121 on the mounting portion 122 are evenly spaced apart. Similarly, on the mounting portion 122, the spacing between each two adjacent second sheets 121 is also equal. By arranging each of the first sheets 111 and each of the second sheets 121 at even intervals, a plurality of filter rod slots 20 with the same slot width are formed on the slot plate 10, and after rotating and adjusting the mounting position of the movable part 12, the slot width of each of the filter rod slots 20 also changes synchronously. In this way, a plurality of filter rod slots 20 can be used on the slot plate 10 each time processing is performed, thereby improving processing efficiency.

[0053] It is understandable that the two sides of a second sheet 121 will respectively form two filter rod slots 20 with two adjacent first sheets 111. When the second sheet 121 is not located in the exact center between the two first sheets 111, the slot widths of the filter rod slots 20 on both sides will be different. Therefore, during actual processing, only the filter rod slots 20 on one side will be used. In other words, in this case, the number of filter rod slots 20 on the slot plate structure 100 of the slitting hub wheel that can accommodate filter rods is only half of the actual number of slots. Of course, when the second sheet 121 is located in the exact center between the two first sheets 111, the slot widths of the filter rod slots 20 on both sides will be the same. Therefore, during actual processing, both filter rod slots 20 on both sides can be used.

[0054] The slotted plate structure 100 of the slitting hub wheel adopts a nested structure, with the filter rod slot 20 for accommodating filter rods positioned between the fixed member 11 and the movable member 12. By rotating the movable member 12, filter rods of various diameters can be clamped. Specifically, the slots of the fixed member 11 and the movable member 12 are cut based on the minimum filter rod diameter required for production. For example, the slots of the fixed member 11 and the movable member 12 are cut based on the minimum filter rod diameter of 5.4 mm, which is the common filter rod specification.

[0055] Preferably, in one embodiment, a plurality of the cutting grooves 30 are provided along the circumference of the slot plate 10, and the cutting grooves 30 are spaced apart from each other, and each filter rod slot 20 is provided with a cutting groove 30. The cutting groove 30 is mainly used to avoid the cutter. When the cutter cuts the filter rod, the cutter can extend into the cutting groove 30 to ensure that the cutter cuts the filter rod. It is understandable that the cutting grooves 30 in the prior art are usually distributed in an annular shape on the bearing. In this embodiment, the cutting grooves 30 are not an integral annular structure, but are distributed in sequence at intervals along the circumference of the slot plate 10, and each filter rod slot 20 has a cutting groove 30. It can be understood that, since in this embodiment, the cutting grooves 30 are not distributed in a ring shape, in order to avoid the cutter cutting other parts of the groove plate 10, intermittent processing can be adopted during processing. When one of the filter rod grooves 20 drives the filter rod to the cutting station, the slitting hub wheel stops rotating, and the cutter then extends into the filter rod groove 20 to cut the filter rod. After the cutting is completed, the cutter is retracted, and the slitting hub wheel rotates again to drive the next filter rod groove 20 to the cutting station.

[0056] It should be noted that the lengths required for slitting filter rods of various specifications are not the same. Therefore, the axial positions of the cutting grooves opened on the bearings of various specifications in the prior art will also be different. Since the slot plate structure 100 of the slitting hub wheel needs to be adapted to filter rods of various specifications for use, it is necessary to concentrate multiple cutting grooves at different positions on the slot plate 10. At this time, there will be some problems. For example, the axial spacing between some adjacent cutting grooves is too small, making it difficult to ensure processing accuracy. At the same time, the cutting grooves of filter rods of different specifications may overlap, resulting in the cutting grooves being too wide, which in turn causes the rod material to bend and deform during the cutting process. By arranging multiple cutting grooves 30 spaced apart from each other along the circumferential direction, the arrangement of the cutting grooves 30 can be facilitated, and the cutting grooves 30 at different positions can be opened on different filter rod slots 20, so that filter rods of different specifications can be better adapted for use.

[0057] Preferably, in one embodiment, a plurality of the cutting grooves 30 are distributed at each of the filter rod slots 20, and the cutting grooves 30 are spaced apart from each other along the axial direction of the slot plate 10. That is to say, in this embodiment, there are a plurality of the cutting grooves 30 at one of the filter rod slots 20, and the plurality of the cutting grooves 30 distributed on this filter rod slot 20 are spaced apart from each other along the axial direction. Through this structure, one of the filter rod slots 20 can be adapted to use with filter rods of various specifications, thereby further improving processing efficiency. It should be noted that when the axial spacing between the cutting grooves 30 to be opened is too close, in order to avoid the spacing between the two being too small or overlapping, one of the cutting grooves 30 can be opened at another of the filter rod slots 20 to avoid affecting the processing of the rod material.

[0058] Preferably, in one embodiment, the cutting groove 30 includes a first groove body 31 and a second groove body 32 adapted to the first groove body 31. The first groove body 31 is formed on the circumferential edge of the first sheet 111 and the outer periphery of the fixing member 11, and the second groove body 32 is formed on the circumferential edge of the second sheet 121. In other words, in this embodiment, a complete cutting groove 30 is composed of the first sheet 111, the second sheet 121, and the groove bodies on the fixing member 11, thereby better adapting to filter rods of different specifications for use.

[0059] Preferably, in one embodiment, the first trough 31 is formed on both sides of the circumferential edge of the first sheet 111, and the second trough 32 is formed on both sides of the circumferential edge of the second sheet 121. In other words, in this embodiment, the first trough 31 is formed on both sides of the first sheet 111, thereby forming the cutting groove 30 on both sides. Similarly, the second trough 32 is formed on both sides of the second sheet 121, thereby forming the cutting groove 30 on both sides.

[0060] Preferably, in one embodiment, a plurality (at least two) of the filter rod slots 20 sequentially distributed along the circumference of the slot plate 10 form a filter rod slot group 200, and the positions of the cutting grooves 30 distributed on each filter rod slot 20 in each filter rod slot group 200 are different. In other words, a plurality of adjacent filter rod slots 20 can be grouped together, and the positions of the cutting grooves 30 provided on each filter rod slot 20 in this filter rod slot group 200 are different, so that different filter rod slots 20 in the filter rod slot group 200 can be adapted to filter rods of different specifications for cutting and use.

[0061] Please refer to Figure 4 , for example, in Figure 4In the embodiment shown, each of the four adjacent filter rod slots 20 can be grouped into a filter rod slot group 200. For ease of description, the four filter rod slots 20 in a filter rod slot group 200 are sequentially divided into work station numbers: 1, 2, 3, and 4. The positions of the cutting grooves 30 specifically distributed on the filter rod slots 20 corresponding to each work station number are different, so that the filter rod slots 20 of each work station number can be used for the production of filter rods of at least one specification. The different positions of the cutting grooves 30 distributed on each filter rod slot 20 in each filter rod slot group 200 means that the cutting grooves 30 distributed on each filter rod slot 20 are completely different or partially different. In other words, the distribution of the cutting grooves 30 in each filter rod slot 20 in a filter rod slot group 200 will not be completely consistent.

[0062] Please refer to Figure 4 and Figure 5 . Preferably, in one embodiment, along the circumference of the slot plate 10, the filter rod slot groups 200 are sequentially distributed in a plurality of groups, and in each group of the filter rod slot groups 200, there is a filter rod slot 20 on which the cutting groove 30 distributed is completely matched. Wherein, in each group of the filter rod slot groups 200, there is a filter rod slot 20 on which the cutting groove 30 distributed is completely matched, which means that the axial distribution positions of the cutting grooves 30 on these filter rod slots 20 are completely matched. For example, Figure 4 In the illustrated embodiment, the cutting grooves 30 distributed on the filter rod slot 20 at station number 1 completely match, the cutting grooves 30 distributed on the filter rod slot 20 at station number 2 completely match, the cutting grooves 30 distributed on the filter rod slot 20 at station number 3 completely match, and the cutting grooves 30 distributed on the filter rod slot 20 at station number 4 completely match. In other words, every four stations constitute a cycle, corresponding to four groups of rods in sequence.

[0063] Specifically, in one embodiment, the 32 filter rod slots 20 on the slot plate 10 are divided into four workstations, with each four workstations forming a cycle, corresponding to four groups of rods in sequence. By designing the distribution of the cutting grooves 30 based on workstations and work areas, it is possible to avoid situations where the spacing between the cutting grooves 30 is too small or they overlap, thereby better ensuring the filter rod cutting effect. More preferably, to ensure the cutting effect, the axial distance between two adjacent cutting grooves 30 is greater than 2 mm.

[0064] More specifically, in order to further improve production efficiency and increase the number of filter rod slots 20 that can be used in each production, the filter rod slots 20 of each workstation number can be adapted to the production of multiple rod material numbers. Figure 5 As shown, Figure 5The numbers on the left side of the filter rod slots represent the rod material numbers in Table 1 above, so as to achieve the optimal distribution of the filter rod slots 20 and the cutter slots 30. In the axial direction, the filter rod slots 20 can be divided into multiple areas, for example Figure 5 Areas A, B and C are shown to better meet the needs of slitting filter rods of different specifications.

[0065] Preferably, in one embodiment, a threaded hole 112 is provided on the end face of the fixing member 11, and the mounting portion 122 is connected to the threaded hole 112 by a bolt. A mounting groove 1221 is provided on the mounting portion 122 corresponding to the threaded hole 112, and the mounting groove 1221 extends along the circumference of the slot plate 10. That is to say, in this embodiment, the movable member 12 is detachably connected to the fixing member 11 by bolts, and the mounting groove 1221 provided on the movable member 12 is a circular arc groove, and this circular arc groove extends along the circumference, so that after loosening the bolt, the position of the movable member 12 can be rotated along the circumference, and after the rotation is completed, there is still an area on the mounting groove 1221 corresponding to the threaded hole 112, so that the position of the movable member 12 can continue to be fixed by tightening the bolt, thereby completing the adjustment of the mounting position of the movable member 12 and realizing the adjustment of the slot width of the filter rod slot 20. Of course, in other embodiments, any other desired structure may be used to achieve multiple mounting positions for the connection and fixation between the movable member 12 and the fixed member 11. In this embodiment, the circumferentially extending mounting groove 1221 is used to facilitate the operator to manipulate and adjust the movable member 12.

[0066] Please refer to Figure 1 and 6 At the same time, in one embodiment, a slitting hub wheel 1000 is also provided, which includes a hub wheel shaft 300, a hub wheel body 400, and a slot plate structure 100 of the slitting hub wheel. The hub wheel body 400 is disposed on the hub wheel shaft 300, and the fixing member 11 is disposed on the outer periphery of the hub wheel body 400. The slitting drum wheel 1000 can be specifically installed on the back plate 2000 of the filter rod slitting device.

[0067] Preferably, in one embodiment, the slitting hub wheel 1000 operates intermittently. Specifically, the intermittent operation of the slitting hub wheel 1000 can be achieved by using an intermittent drive mechanism or a corresponding connection structure. For example, the hub wheel shaft 300 can be driven by an intermittently operating motor; or the hub wheel shaft 300 can be connected to the motor via a dial 301, wherein the pin of the dial 301 is inserted into the sheave 302, and the sheave 302 is connected to the hub wheel shaft 300. The motor provides power to the dial 301 to rotate it at a constant speed, and the dial 301 causes the sheave 302 to perform intermittent motion.

[0068] Specifically, in one embodiment, the hub axle 300 and the sheave 302 are circumferentially fixed by a flat key 303 , the right end of the hub axle 300 is threaded, and the hub axle 300 is axially fixed by a shoulder and a hexagonal locking nut 600 .

[0069] Specifically, in one embodiment, the hub wheel body 400 is connected to the hub wheel axle 300 via a hub wheel core 401. Specifically, the hub wheel core 401 is connected to the hub wheel axle 300 via a connecting flange 402, and the hub wheel body 400 is connected to the hub wheel core 401 via long bolts.

[0070] Preferably, in one embodiment, a groove 113 is provided on the inner periphery of the fixing member 11, and a protrusion matching the groove 113 is provided on the outer periphery of the hub wheel body 400, and the fixing member 11 is circumferentially fixed to the hub wheel body 400 through the interlocking structure between the groove 11 and the protrusion.

[0071] Preferably, in one embodiment, a double-row angular contact ball bearing 304 and a first deep groove ball bearing 305 are installed on the hub axle 300, so as to reduce friction during rotation and improve rotation accuracy.

[0072] Specifically, in one embodiment, a bearing compression sleeve 306 and a bearing cover 307 are provided on one side of the double-row angular contact ball bearing 304, and a bearing outer ring bushing 308 and a bearing bushing 309 are provided on the other side of the double-row angular contact ball bearing 304. The double-row angular contact ball bearing 304 is axially fixed by the bearing compression sleeve 306, the bearing cover 307, the bearing outer ring bushing 308, and the bearing bushing 309. Specifically, in one embodiment, a retaining washer 310 is also provided to prevent axial sliding of the double-row angular contact ball bearing 304. Specifically, both sides of the first deep groove ball bearing 305 are axially fixed by the bearing outer ring bushing 308, the bearing bushing 309, and the shaft shoulder.

[0073] Preferably, in one embodiment, a hub wheel core shaft 311 is provided between the hub wheel core 401 and the hub wheel axle 300, and a second deep groove ball bearing 312 is provided between the hub wheel core 401 and the hub wheel core shaft 311. Specifically, in one embodiment, both sides of the second deep groove ball bearing 312 are axially fixed by elastic circlips 313 and shaft shoulders.

[0074] Preferably, in one embodiment, a sealing ring 313 is provided between the end surface of the hub wheel core 401 and the hub wheel spindle 311. Specifically, in one embodiment, the hub wheel spindle 311 and the sealing ring 313 are fixed to the back plate 2000 by bolts.

[0075] Preferably, in one embodiment, a slitting cover plate 500 is further provided on the outside of the slot plate 10. The slitting cover plate 500 may be provided with a corresponding avoidance structure corresponding to the position of the cutting knife slot 30 to avoid the cutting knife. The slitting cover plate 500 primarily functions to compress the filter rod until it is slightly deformed, preventing the filter rod from rotating in the filter rod slot 20 and causing poor slitting performance.

[0076] The slitting cover plate 500 is disposed at the slitting station of the slitting hub wheel 1000 and is spaced apart from the slitting hub wheel 1000. Specifically, when the filter rod slot 20 rotates to the slitting station, the distance between the inner surface of the slitting cover plate 500 and the bottom of the filter rod slot 20 is smaller than the diameter of the filter rod, so that the inner surface of the slitting cover plate 500 can squeeze the filter rod accordingly, thereby pressing the filter rod tightly into the filter rod slot 20, thereby preventing the filter rod from rotating in the filter rod slot 20 when the cutter cuts the filter rod.

[0077] Specifically, the slitting cover plate 500 can be installed on the back plate 2000. It is only necessary that a part of the structure on the slitting cover plate 500 is located at the slitting position of the slitting hub wheel 1000 and is spaced from the slitting hub wheel 1000, so that the filter rod located at the slitting position of the slitting hub wheel 1000 can be pressed by the corresponding structure on the slitting cover plate 500.

[0078] It should be noted that, considering that the diameters of the filter rods of various specifications to be cut are different, and the positions of the cutting grooves 30 distributed on the filter rod slots 20 at each station are different, the cutting cover plate 500 is a standard part, and different specifications can be designed according to the specifications of the filter rods to be generated. For example, as in the above embodiment, the filter rod slots 20 of four different stations have different positions of the cutting grooves 30, so four sets of cutting cover plates 500 of different specifications can be made accordingly; and the 5.4mm and 6.3mm filter rods share the same thickness cover plate, and the 7.1mm and 7.4mm filter rods share another thickness cover plate, so the cutting cover plates 500 have 4*2 sets of different specifications, and one cutting hub wheel 1000 can be adapted to 8 sets of cutting cover plates 500 of different specifications.

[0079] The above description is only an embodiment of the present invention. It should be pointed out that those skilled in the art can make improvements without departing from the creative concept of the present invention, but these improvements all fall within the scope of protection of the present invention.
