Description

TECHNICAL FIELD

[0001] The present application relates to a pressing device of a cutting bed, and belongs to the technical field of cutting beds. BACKGROUND

[0002] The cutting bed is a cutting device used in the textile and garment industry, the leather industry, the automobile seat industry, the furniture industry, etc. In actual production process, it is often necessary to cut multiple layers of materials (cloth or fabric) at the same time. When cutting multiple layers of materials at the same time, the multiple layers of cloth are generally placed in a stacked manner on a conveying belt for conveying, but the upper layer of material and the lower layer of material are prone to displacement during conveying, resulting in inconsistent cutting. In order to solve the above problem, the existing technology adopts the mode of uniformly distributing a plurality of air suction holes on the conveying belt to form an air suction effect inside, so as to adsorb the multiple layers of materials on the conveying belt through the air suction effect. However, this mode can only be applied to materials that are breathable, and the anti-displacement effect is not good for some dense or non-breathable materials. SUMMARY

DETAILED DESCRIPTION

[0068] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the cutting bed pressing device of the present application is specifically described below in combination with the embodiments and the drawings.

[0069] The present embodiment provides a cutting bed pressing device with better anti-displacement effect.

[0071] AsFigures 1 to 4 As shown, the pressing device 100 of the cutting bed in the embodiment is arranged on the cutting bed where the conveying line 6 is arranged, and in the embodiment, the conveying line 6 of the cutting bed is a conveying belt. The pressing device 100 of the cutting bed comprises a synchronous pressing assembly 1, a lifting driving assembly 4 and two machine bases 5. The two machine bases 5 are respectively arranged at the two ends of the synchronous pressing assembly 1, and are used to suspend and support the synchronous pressing assembly 1 and the lifting driving assembly 4. The synchronous pressing assembly 1 comprises a first pressing roller group 11 and a second pressing roller group 12, both of which are arranged above the conveying line 6 and the lower surfaces of both are at the same height. The area between the lower surfaces of the first pressing roller group 11 and the second pressing roller group 12 and the upper surface of the conveying line 6 constitutes a material passing channel 2. The first pressing roller group 11 and the second pressing roller group 12 are arranged in parallel and are spaced apart along the conveying direction of the conveying line 6, and the gap between them constitutes a tool passing space 3 which is configured to allow the cutting tool of the cutting bed to move. The lifting driving assembly 4 is used to drive the first pressing roller group 11 and the second pressing roller group 12 to synchronously lift relative to the conveying line 6 to adjust the height of the material passing channel 2. The first pressing roller group 11 at least comprises an outer first synchronous belt 111, and the second pressing roller group 12 at least comprises an outer second synchronous belt 121. The first synchronous belt 111 and the second synchronous belt 121 can perform annular motion along the length direction thereof, and together constitute a movable pressing part which can move synchronously with the conveying line 6, and the movable pressing part is used to press the material during the cutting process.

[0072] It can be understood that before cutting, the staff can adjust the height of the material passing channel 2 according to the thickness of the multi-layer material to be cut, so that the first pressing roller group 11 and the second pressing roller group 12 can realize the pressing of the multi-layer material when the multi-layer material enters the material passing channel 2. Specifically, the first pressing roller group 11 and the second pressing roller group 12 are driven by the lifting driving assembly 4 to be lifted synchronously relative to the conveying line 6, so that it can also be applicable to materials with different number of layers or different thickness of single layer, and at the same time, the downward pressing force of the first pressing roller group 11 and the second pressing roller group 12 on the material can be adjusted according to the actual cutting requirement. During the cutting process, the multi-layer material is placed on the conveying line 6 of the cutting bed, and the multi-layer material moves into the material passing channel 2 under the action of the conveying line 6. When the multi-layer material enters the material passing channel 2 and reaches the cutting position, i.e. there is multi-layer material on both sides of the tool path space 3, the cutting tool of the cutting bed can extend into the material passing channel 2 through the tool path space 3 to cut the multi-layer material. During cutting, the cutting tool moves transversely along the extension direction of the tool path space 3. When the multi-layer material is at this position in the material passing channel 2, the outer surfaces of the first synchronous belt 111 and the second synchronous belt 121 contact the uppermost layer of the material and apply a downward pressing force to it. Since the multi-layer material needs to move back and forth on the conveying line 6 during the cutting process to cooperate with the transverse movement of the cutting tool to cut the multi-layer material into a specified shape, the movable pressing part formed by the first synchronous belt 111 and the second synchronous belt 121 can move synchronously with the conveying line 6, which means that the movable pressing part can work with the conveying line 6 to realize the conveying of the multi-layer material. Therefore, the first synchronous belt 111 and the second synchronous belt 121 can press the multi-layer material while moving synchronously with the multi-layer material, so as to realize the pressing of the multi-layer material during movement to prevent displacement of the layers, and it can be applicable to various types of materials, not limited to air-permeable or air-impermeable materials. Therefore, compared with the prior art, it has better anti-displacement effect.

[0073] In addition, to realize the pressing effect, it is necessary to ensure that the height of the material passing channel 2 is less than the thickness of the multi-layer material in a free state. When the head end of the multi-layer material just enters the area below the first synchronous belt 111 or the second synchronous belt 121 in the material passing channel 2, due to the arc structure at both ends of the first synchronous belt 111 and the second synchronous belt 121, the multi-layer material will have a gradual pressing process when it enters, thereby reducing the risk of displacement of the uppermost layer of the material.

[0074] Figure 5 It is an internal structure diagram of the synchronous pressing assembly in the embodiment of the application.

[0075] As Figure 5As shown, the first compression roller set 11 further comprises three first synchronous shafts 112 and three first synchronous rollers 113. Two of the first synchronous shafts 112 are arranged in parallel to the conveying direction of the conveying line 6, and the third first synchronous shaft 112 is raised vertically relative to the other two first synchronous shafts 112, and all of them are arranged on the inner side of the first synchronous belt 111. The raised first synchronous shaft 112 is arranged on the radially outer side of the first synchronous shaft 112 that is relatively far away from the second compression roller set 12 and is parallel to it, and is located above the inclined side of the first synchronous shaft 112 that is relatively far away from the other first synchronous shaft 112. The three first synchronous rollers 113 are respectively fixedly sleeved on the three first synchronous shafts 112 and are in meshing connection with the first synchronous belt 111. The first synchronous belt 111 is taut on the three first synchronous rollers 113, and the first synchronous shaft 112 drives the first synchronous belt 111 to move through the first synchronous rollers 113.

[0076] It can be understood that the first synchronous shaft 112 can drive the corresponding first synchronous roller 113 to rotate when rotating, thereby driving the first synchronous belt 111 to move, and further realizing the synchronous movement of the first synchronous belt 111 and the conveying line 6. When the multi-layer material is fed from the side of the first compression roller set 11, since one of the first synchronous shafts 112 is raised vertically relative to the other two first synchronous shafts 112 by a certain distance, after the first synchronous belt 111 is taut on the three first synchronous rollers 113, an inclined surface is formed below the raised first synchronous shaft 112, so that the material passing channel 2 has a tendency to gradually narrow relative to the feeding direction of the multi-layer material, thereby ensuring that the multi-layer material has a relatively long process of gradual compression when entering the material passing channel 2, and thus the risk of displacement of the uppermost layer of material can be further reduced.

[0077] In other alternative embodiments, the first compression roller set 11 can only comprise two first synchronous shafts 112 and two first synchronous rollers 113, i.e. without the raised first synchronous shaft 112, the first synchronous belt 111 is taut on the two first synchronous rollers 113, and the first synchronous shaft 112 drives the first synchronous belt 111 to move through the first synchronous rollers 113. In this way, the multi-layer material is guided into the material passing channel 2 through the circular arc structure formed after the first synchronous belt 111 is taut on the two first synchronous rollers 113, so that the multi-layer material has a process of gradual compression, thereby reducing the risk of displacement of the uppermost layer of material.

[0078] As Figure 5As shown, the second pressing roller group 12 also includes two second synchronous shafts 122 and two second synchronous rollers 123. The two second synchronous shafts 122 are spaced apart along the conveying direction parallel to the conveyor line 6, and are both located inside the second synchronous belt 121. The two second synchronous rollers 123 are respectively fixedly sleeved on the two second synchronous shafts 122 and meshed with the second synchronous belt 121. The second synchronous belt 121 is taut on the two second synchronous rollers 123, and the second synchronous shafts 122 drive the second synchronous belt 121 to move through the second synchronous rollers 123.

[0079] Understandably, when the second synchronous shaft 122 rotates, it can drive the corresponding second synchronous roller 123 to rotate, thereby driving the second synchronous belt 121 to move, and thus realizing the synchronous movement of the second synchronous belt 121 and the conveyor line 6.

[0080] In this embodiment, the diameter of all first synchronous shafts 112 is the same as the diameter of all second synchronous shafts 122, the diameter of all first synchronous rollers 113 is the same as the diameter of all second synchronous rollers 123, and the axes of the first synchronous shafts 112 and the second synchronous shafts 122, which are spaced apart along the conveying direction parallel to the conveying line 6, are located on the same horizontal plane. The thickness of the first synchronous belt 111 and the second synchronous belt 121 is the same, so as to ensure that the lower surfaces of the first pressing roller group 11 and the second pressing roller group 12 are at the same height.

[0081] In this embodiment, the first synchronous belt 111 and the second synchronous belt 121 each include a plurality of synchronous belt units, which are arranged sequentially along the axial direction of the first synchronous shaft 112 or the second synchronous shaft 122; the first synchronous roller 113 and the second synchronous roller 123 each include a plurality of synchronous roller units, which correspond one-to-one with the synchronous belt units.

[0082] like Figure 5 As shown, both the first pressure roller group 11 and the second pressure roller group 12 further include two crossbeams 13, which are disposed in the area between two first synchronous shafts 112 or second synchronous shafts 122 that are spaced apart along the conveying direction parallel to the conveying line 6. The two crossbeams 13 are used to rotatably support the corresponding first synchronous shaft 112 or second synchronous shaft 122, forming multi-point support in the axial direction of the first synchronous shaft 112 or second synchronous shaft 122. A plurality of retaining bodies 14 are disposed in the area between the two crossbeams 13 within the first pressure roller group 11 and the second pressure roller group 12, and these retaining bodies 14 are spaced apart along the extending direction of the crossbeams 13. Each retaining body 14 has a first retaining end and a second retaining end disposed opposite to each other. The first retaining end can abut against one end of one crossbeam 13 facing the retaining body 14, and the second retaining end can abut against one end of the other crossbeam 13 facing the retaining body 14.

[0083] It can be understood that, since the first synchronous belt 111 is taut on the plurality of first synchronous rollers 113, and the second synchronous belt 121 is taut on the plurality of first synchronous rollers 113, in use, the first synchronous belt 111 and the second synchronous belt 121 always respectively exert an inward reaction force on the first synchronous shaft 112 and the second synchronous shaft 122, so that the first synchronous shaft 112 and the second synchronous shaft 122 have a tendency to bend and deform inwardly, and once bending occurs, the corresponding synchronous belt is in a slack state, and the synchronous belt in the slack state is difficult to achieve the compression effect on the multi-layer material, and the arrangement of the plurality of retaining bodies 14 can prevent the first synchronous shaft 112 and the second synchronous shaft 122 from bending and deforming inwardly, specifically through the abutting cooperation between the first retaining end of the retaining body 14 and one of the beam members 13 and the abutting cooperation between the second retaining end of the retaining body 14 and the other beam member 13, so as to be transversely supported between the two beam members 13, and since the two beam members 13 form multi-point support in the axial direction of the corresponding synchronous shaft, the first synchronous shaft 112 and the second synchronous shaft 122 are indirectly radially supported inwardly, so as to resist the reaction force of the synchronous belt on the synchronous shaft, thereby effectively preventing the first synchronous shaft 112 and the second synchronous shaft 122 from bending and deforming inwardly, thereby ensuring that the first synchronous belt 111 and the second synchronous belt 121 are always in a taut state during use, and further ensuring the compression effect of the first synchronous belt 111 and the second synchronous belt 121 on the multi-layer material.

[0084] In the embodiment, each beam member 13 has a plurality of support seats 131, which form multi-point support in the axial direction of the corresponding synchronous shaft, and the plurality of support seats 131 are arranged at intervals along the extension direction of the beam member 13, and the first synchronous shaft 112 and the second synchronous shaft 122 are respectively rotatably supported on the plurality of support seats 131 on the corresponding beam member 13.

[0085] In the embodiment, the two beam members 13 in the first compression roller group 11 are profiled members, which can be aluminum profiles, and the two beam members 13 in the second compression roller group 12 are plate members, which can be metal plate members, and are in the shape of L. In addition, the distance between the two beam members 13 in the first compression roller group 11 is greater than the distance between the two beam members 13 in the second compression roller group 12.

[0086] In the embodiment, one beam member 13 in the first compression roller group 11 is used to support one of the first synchronous shafts 112, and the other beam member 13 is used to simultaneously support the other first synchronous shaft 112 and the raised first synchronous shaft 112; and the two beam members 13 in the second compression roller group 12 are used to respectively support the two second synchronous shafts 122.

[0087] Figure 6 is a schematic view of a three-dimensional structure of the holding body in an embodiment of the present application.

[0088] As shown in Figure 6 , the holding body 14 comprises two abutting blocks 141, two locking blocks 142 and a first threaded fastener (not shown in the figure). The two abutting blocks 141 are symmetrically arranged along the gap direction between the two beam members 13, and the outer ends of the two abutting blocks 141 away from each other constitute a first holding end and a second holding end. The two locking blocks 142 are arranged in a manner of abutting between the two abutting blocks 141, and are symmetrically arranged along the height direction of the abutting blocks 141. Part or all of the first threaded fastener passes through the two locking blocks 142, which is used to unlock or lock the two abutting blocks 141. In this embodiment, the first threaded fastener is a screw. Each of the abutting blocks 141 and the locking blocks 142 has two inclined surface parts, and the two inclined surface parts on the same locking block 142 are in contact with the two inclined surface parts on the same side of the two abutting blocks 141, respectively. When the two locking blocks 142 are close to each other along the height direction of the abutting blocks 141 under the action of the first threaded fastener, the two abutting blocks 141 are away from each other along the gap direction between the two beam members 13.

[0089] It can be understood that the two abutting blocks 141 are in abutment with the two beam members 13, respectively, under the ejection action of the two locking blocks 142, so that when the first threaded fastener locks the two locking blocks 142, the holding member supports the two beam members 13 through the two abutting blocks 141, respectively, to prevent the synchronous shaft on the beam member 13 from bending inward. In addition, when the first threaded fastener is tightened, the two locking blocks 142 are close to each other along the height direction of the abutting blocks 141 under the action of the first threaded fastener, so that the two abutting blocks 141 are away from each other along the gap direction between the two beam members 13. When the first threaded fastener is loosened, the two abutting blocks 141 no longer move relative to each other. When the first threaded fastener is loosened to a certain extent, the two abutting blocks 141 can move freely. Therefore, the position of the two abutting blocks 141 relative to the two beam members 13 can be adjusted by tightening the first threaded fastener, and the position of the abutting block 141 can be quickly adjusted, so that after the positions of the two beam members 13 are fixed, the positions of the two abutting blocks 141 can be adjusted according to the actual gap between the two beam members 13, so as to ensure that the outer ends of the two abutting blocks 141 can abut against the side surfaces of the beam members 13 after the abutting body is installed, and the tightness of the abutting block 141 and the beam member 13 can also be adjusted according to actual needs, so as to realize the adjustment of the supporting force. The tighter the abutting block 141 and the beam member 13 are, the greater the supporting force is, and the better the supporting effect is.

[0090] As shown in Figure 5As shown, the synchronous pressing assembly 1 further comprises two roller frames 15, which are respectively arranged at two ends of the first pressing roller group 11 and the second pressing roller group 12, and are used for fixedly supporting the first pressing roller group 11 and the second pressing roller group 12. The two ends of the two cross beam members 13 in the first pressing roller group 11 and the second pressing roller group 12 are respectively fixedly supported by the two roller frames 15. It can be understood that the two ends of all the cross beam members 13 can be fixedly supported by the two roller frames 15, and since each cross beam member 13 is respectively rotatably supported by the corresponding first synchronous shaft 112 or the second synchronous shaft 122, the stable support of all the first synchronous shafts 112 and the second synchronous shafts 122 can be realized, so that the first synchronous shafts 112 and the second synchronous shafts 122 can stably rotate, thereby driving the first synchronous belt 111 and the second synchronous belt 121 to stably move.

[0091] Figure 7 is a schematic view of a three-dimensional structure of a split roller frame in an embodiment of the present application.

[0092] As shown in Figure 7 , one of the roller frames 15 is a split structure, and the roller frame 15 comprises a first frame body 151, a second frame body 152 and a connecting body 153. The first frame body 151 is used for fixedly supporting the same side ends of the two cross beam members 13 in the first pressing roller group 11. The second frame body 152 is used for fixedly supporting the same side ends of the two cross beam members 13 in the second pressing roller group 12. The connecting body 153 is arranged between the first frame body 151 and the second frame body 152, and is used for detachably connecting the first frame body 151 and the second frame body 152 together.

[0093] It can be understood that, since the first synchronous shaft 112 and the second synchronous shaft 122 are arranged at the inner side of the first synchronous belt 111 and the second synchronous belt 121 respectively, so that when the first synchronous shaft 112 and the second synchronous shaft 122 are installed, they need to pass through the first synchronous belt 111 and the second synchronous belt 121 respectively, and correspondingly, the two beam members 13 in the first pressing roller set 11 and the second pressing roller set 12 also need to pass through the first synchronous belt 111 and the second synchronous belt 121 respectively, so that when installed, the first synchronous shaft 112 and the second synchronous shaft 122 can be installed on the corresponding beam member 13 first, and then one end of each beam member 13 is fixedly connected with the other roller frame 15, after the first synchronous belt 111 and the second synchronous belt 121 are installed, the first frame body 151 is fixedly connected with the other end of the two beam members 13 in the first pressing roller set 11, and the second frame body 152 is fixedly connected with the other end of the two beam members 13 in the second pressing roller set 12, and finally the first frame body 151 and the second frame body 152 are connected together through the connecting body 153, compared with two roller frames 15 which are integral type, this kind of way is more convenient when installed, at the same time, the first synchronous shaft 112 and the second synchronous shaft 122 can be quickly installed, and the first synchronous shaft 112 and the second synchronous shaft 122 after installation are independent of each other, when a single synchronous shaft needs to be disassembled, only the frame body corresponding to the synchronous shaft needs to be separated first, and then the corresponding synchronous shaft is pulled out from one side of the frame body, without the need to disassemble the other frame body, which is convenient for subsequent maintenance.

[0094] In the embodiment, one of the roller frames 15 is of an integral structure, and the other roller frame 15 is of a split structure. In other alternative embodiments, both of the roller frames 15 can be of a split structure or an integral structure.

[0095] Figure 8 is a schematic view of the three-dimensional structure of the connecting body in the embodiment of the application.

[0096] As Figure 8As shown, the connector 153 comprises two connecting blocks 153a, an upper clamping block 153b, a lower clamping block 153c and a second threaded fastener (not shown in the figure). The two connecting blocks 153a are respectively fixed at the inner ends of the first frame body 151 and the second frame body 152 which are close to each other. The upper clamping block 153b is arranged above the two connecting blocks 153a in a manner of close contact and is respectively matched with the two connecting blocks 153a through inclined surfaces. The lower clamping block 153c is arranged below the two connecting blocks 153a in a manner of close contact and is respectively matched with the two connecting blocks 153a through inclined surfaces. Part or all of the second threaded fastener passes through the upper clamping block 153b and the lower clamping block 153c, and is used to unlock or lock the two connecting blocks 153a. In the embodiment, the second threaded fastener is a screw. When the upper clamping block 153b and the lower clamping block 153c are close to each other under the action of the second threaded fastener, the two connecting blocks 153a are locked between the upper clamping block 153b and the lower clamping block 153c.

[0097] Understandably, when the second threaded fastener is screwed, the upper clamping block 153b and the lower clamping block 153c are close to each other under the action of the second threaded fastener, and the two connecting blocks 153a are locked between the upper clamping block 153b and the lower clamping block 153c under the action of the inclined surface matching, so that the first frame body 151 and the second frame body 152 can be connected together, and quick installation can be realized with good connection stability. When the second threaded fastener is loosened, the upper clamping block 153b and the lower clamping block 153c no longer move relative to each other. When the second threaded fastener is loosened to a certain extent, the two connecting blocks 153a can be freely moved, and at this time, the first frame body 151 and the second frame body 152 can be separated.

Understandably, the adjustment of the distance between the two cross beam members 13 in the first compression roller group 11 can be realized by adjusting the position of the cross beam member 13 during installation, so as to adjust the distance between the two first synchronous shafts 112 on the two cross beam members 13, so as to eliminate the installation error and make the installed first synchronous belt 111 keep tight.

[0100] In the embodiment, the ends of the two beam members 13 in the first compression roller set 11 are connected to the roller frames 15 by screws, and the sides of the two roller frames 15 are respectively provided with two groups of first waist-shaped holes 154 corresponding to the two ends of one of the beam members 13, the first waist-shaped holes 154 extend along the conveying direction parallel to the conveying line 6, each group includes two first waist-shaped holes 154, and the two first waist-shaped holes 154 in the same group are arranged at intervals along the conveying direction parallel to the conveying line 6, and the screws at the two ends of the beam member 13 pass through the corresponding first waist-shaped holes 154. Specifically, one group of first waist-shaped holes 154 is arranged on the side of the first frame body 151, and the other group of first waist-shaped holes 154 is arranged on the side of the other integral roller frame 15.

[0101] As shown in Figure 9 and Figure 10 , the same side ends of the two beam members 13 in the second compression roller set 12 are movably fixedly connected to one of the roller frames 15, so that the ends of the two beam members 13 can be adjusted in position along the conveying direction parallel to the conveying line 6. Understandably, the inclination of the two beam members 13 in the second compression roller set 12 can be adjusted by adjusting the position of one of the ends of the beam members 13 during installation, so as to adjust the inclination of the second synchronous shafts 122 on the two beam members 13, so as to eliminate installation errors and keep the two second synchronous shafts 122 parallel, so that the installed second synchronous belt 121 is kept taut.

[0102] In the embodiment, the ends of the two beam members 13 in the second compression roller set 12 are connected to the roller frames 15 by screws, and the side of one of the roller frames 15 is provided with two second waist-shaped holes 155 corresponding to the same side ends of the two beam members 13, the second waist-shaped holes 155 extend along the conveying direction parallel to the conveying line 6, and the two second waist-shaped holes 155 are arranged at intervals along the conveying direction parallel to the conveying line 6, and the screws at the same side ends of the two beam members 13 pass through the corresponding second waist-shaped holes 155. Specifically, the two second waist-shaped holes 155 are arranged on the side of the second frame body 152.

[0103] As shown in Figure 9 , the synchronous compression assembly 1 further comprises a driving component 16 arranged on one of the roller frames 15 for driving one of the first synchronous shafts 112 and one of the second synchronous shafts 122 to rotate.

[0104] The drive unit 16 includes a drive motor 161, a synchronous belt drive assembly 162, and a tension pulley 163. The drive motor 161 is fixedly mounted on one of the roller frames 15. The output shaft of the drive motor 161 is poweredly connected to the synchronous belt drive assembly 162. One end of a first synchronous shaft 112 extends into the roller frame 15 and is poweredly connected to the synchronous belt drive assembly 162, and one end of a second synchronous shaft 122 extends into the roller frame 15 and is poweredly connected to the synchronous belt drive assembly 162. Understandably, when the drive motor 161 starts, it drives the first synchronous shaft 112 and the second synchronous shaft 122 to rotate via the synchronous belt drive assembly 162, thereby correspondingly driving the first synchronous belt 111 and the second synchronous belt 121 to move.

[0105] In this embodiment, the drive motor 161 is linked with the motor of the conveyor line 6, and both output the same speed and direction during operation.

[0106] The tensioning pulley 163 is used to keep the synchronous belt in the synchronous belt drive assembly 162 taut. The tensioning pulley 163 is movably mounted on the roller frame 15 through the cooperation of a slotted hole and a screw.

The synchronous belt drive group 162 is poweredly connected to a first synchronous shaft 112 and a second synchronous shaft 122 that are relatively close to each other.

[0109] like Figure 2 and Figure 11 As shown, there are two lifting drive components 4, each mounted on a separate base 5. Each includes a linear actuator 41, a lifting seat 42, and a connecting plate 43.

The lifting seat 42 is fixedly mounted at the output end of the linear actuator 41. The lifting seat 42 is fixedly connected to the corresponding roller frame 15 via the connecting plate 43. Understandably, when the linear actuator 41 operates, it drives the lifting seat 42 to move up and down, thereby driving the first pressing roller group 11 and the second pressing roller group 12 to move synchronously relative to the conveyor line 6. In this embodiment, the linear actuator 41 is a lead screw slide, and the lifting seat 42 is fixedly mounted on the slide within the lead screw slide. In other alternative embodiments, the linear actuator 41 can also be a hydraulic cylinder, an electric push rod, or other driving elements; no limitation is made here.
