Description

Technical Field

[0001] The present application relates to the technical field of paper container processing, and in particular to a paper sheet synchronous conveying roller pressing mechanism and paper container manufacturing equipment. Background Art

[0002] Paper tableware is becoming a fashion trend. Paper cups and paper containers are now widely used in catering. Various paper cups, containers, and paper forming and processing equipment are booming. Paper sheets, as raw materials before forming paper cups and paper containers, need to be milled, marked, glued, folded, rolled, and other processing procedures on paper edge trimming equipment. The rolling station is a very important station in paper processing. Existing paper processing equipment uses a rotating shaft roller method to transport and roll paper sheets at the paper rolling station. However, when the roller-type paper feeding device is used to transport paper sheets, the paper sheets often cannot pass through the rolling area when the paper sheets are too narrow, and scratches are prone to appear on the surface of the paper sheets when the roller conveying method is used. Summary of the invention

[0003] Based on this, it is necessary to provide a paper sheet synchronous conveying and rolling mechanism and paper container manufacturing equipment that can avoid damaging the paper sheet and improve the folding and rolling quality.

[0004] In order to solve the above technical problems, this application provides the following technical solutions:

[0005] A paper sheet synchronous conveying roller pressing mechanism, the paper sheet synchronous conveying roller pressing mechanism comprising:

[0006] The frame includes a pair of symmetrically arranged wall panels;

[0007] A conveying assembly, comprising a pair of conveying roller groups arranged between the two wall panels and in transmission connection, the conveying roller group comprising a driving shaft, a driven shaft and a conveying belt connected between the driving shaft and the driven shaft, the two conveying belts being used to clamp and drive the paper sheets to move;

[0008] A plurality of roller pressing assemblies are arranged close to the conveying assembly and are drivingly connected to the driving shaft. The plurality of roller pressing assemblies are arranged in sequence along the conveying path of the paper sheet and adjacent roller pressing assemblies are meshed and linked to synchronously press the edges of the paper sheet.

[0009] It can be understood that a conveying component is provided to convey paper sheets, and a roller pressing component is provided which is transmission-connected to the conveying component to roll the edge of the paper sheets during the conveyance of the paper sheets. The conveying component and the roller pressing component share a power source, and the transmission synchronization is good and more stable and reliable, thus avoiding the problem that the paper sheets cannot be conveyed. Several roller pressing components are provided on the conveying path of the paper sheets, and the several roller pressing components are meshedly connected with each other, thereby improving the synchronization between the several roller pressing components and thereby improving the rolling effect of the paper sheets.

[0010] In one embodiment, the rolling assembly includes an active rolling group and a driven rolling group which are arranged on the upper surface and the lower surface of the paper sheet and meshingly connected with each other, and the active rolling group is connected to the driving shaft through a pulley structure.

[0011] It can be understood that the active roller pressing group and the driven roller pressing group cooperate to roll the edge of the paper sheet, and the active roller pressing group is connected to the active shaft for transmission, which reduces the power source, reduces the cost, and improves the synchronization of conveying and rolling.

[0012] In one of the embodiments, the paper sheet synchronous conveying roller pressing mechanism further includes an end roller pressing group drivingly connected to the driven shaft.

[0013] It can be understood that, by cooperating with the end rolling group and the rolling assembly, the whole path rolling of the paper sheet during transportation is achieved.

[0014] In one embodiment, the end rolling group includes a pair of end rolling wheels, and the pair of end rolling wheels are respectively arranged on a pair of driven shafts.

[0015] It can be understood that by arranging the end rollers on the driven shaft, the need for additional drive components is avoided, and at the same time, the synchronization of a pair of end rollers is improved by driving the end rollers to rotate through the driven shaft.

[0016] In one of the embodiments, the paper sheet synchronous conveying roller pressing mechanism also includes an adjusting component, and the adjusting component includes a first adjusting member arranged on the frame, and the first adjusting member is pressed against the conveyor belt to adjust the clamping force of the two conveyor belts on the paper sheet.

[0017] It can be understood that an adjustment component is provided on the conveying roller group of the conveying component, and the two conveying belts clamping the paper sheets are pressed by the first adjustment and rolling connection, thereby avoiding the problem that the paper sheets cannot be conveyed.

[0018] In one embodiment, the first adjusting member includes a roller rollingly connected to the conveyor belt and a power member connected to the roller, and the power member is used to drive the roller to move in a direction of tightening or loosening the two conveyor belts.

[0019] It can be understood that by driving the roller and the conveyor belt to roll in connection with each other through the power member, it is convenient to adjust the clamping force of the two conveyor belts on paper sheets of different thicknesses.

[0020] In one embodiment, the first adjusting member includes a mounting bracket connected between the power member and the roller, and the roller is elastically connected to the mounting bracket.

[0021] It can be understood that the installation bracket is driven by the power member to drive the roller to move to compress the conveyor belt. The roller is elastically connected to the installation bracket, so that the roller and the conveyor belt are elastically supported to prevent the roller from applying excessive force to the conveyor belt and affecting the transportation of paper sheets.

[0022] In one embodiment, the mounting bracket includes a mounting plate connected to the power member and a pendulum block mounted on the mounting plate and used to arrange the roller, the pendulum block includes a connecting end rotatably connected to the mounting plate and a movable end swinging relative to the connecting end, the movable end is elastically connected to the mounting plate and is configured to swing in a vertical plane.

[0023] It can be understood that such a configuration facilitates the rolling connection between the roller and the conveyor belt to compress the two conveyor belts, and at the same time makes the roller and the conveyor belt elastically connected to avoid excessive clamping force on the paper pieces, which is beneficial for the roller to give way to the paper pieces to a certain extent during transportation, avoiding the roller from getting stuck in the conveyor belt and causing the paper pieces to be unable to be transported.

[0024] In one embodiment, the swing block includes two movable ends extending from the connecting end to the distal end at an acute angle, a stop block is arranged between the two movable ends, and the movable end of the two movable ends closer to the conveyor belt side is elastically connected to the stop block.

[0025] It can be understood that by arranging two movable ends distributed on both sides of the stop block to limit the swing stroke of the two movable ends, the elastic stroke of the roller after the power component drives the roller to press the conveyor belt is limited, thereby preventing the roller from giving way too much and causing the transmission belt to have too little clamping force on the paper. At the same time, it can also prevent the power component from driving the roller to release the conveyor belt, and the roller's own gravity from falling too much, thereby rendering the elastic connection between the movable end and the stop block ineffective.

[0026] This application also provides the following technical solutions:

[0027] A paper container manufacturing device comprises the paper sheet synchronous conveying roller pressing mechanism as described above.

[0028] It can be understood that such a configuration can effectively avoid damage to the paper sheet, improve the clamping force of the conveyor belt on the paper sheet, and avoid the problem of the paper sheet being unable to be conveyed.

[0029] Compared with the prior art, the synchronous paper conveying and rolling mechanism conveys paper sheets by setting a conveying component, and sets a rolling component transmission-connected to the conveying component to roll the edge of the paper sheet during the paper sheet conveying process. The conveying component and the rolling component share a power source, and the transmission synchronization is good and more stable and reliable, thus avoiding the problem of paper sheets being unable to be conveyed. Several rolling components are set on the conveying path of the paper sheets, and the several rolling components are meshed and connected, thus improving the synchronization between the several rolling components, thereby improving the rolling effect of the paper sheets.

[0030] The present application also provides a paper container manufacturing device, which can effectively avoid damage to the paper skin by setting the above-mentioned paper sheet synchronous conveying roller mechanism, improve the clamping force of the conveyor belt on the paper sheet, and avoid the problem of paper sheets being unable to be conveyed.

[0046] See also Figures 1 to 3 The present application provides a paper sheet synchronous conveying and rolling mechanism 100, which is used to roll the folded edge portion coated with glue on the edge of the paper sheet 200 during the production process of the paper container so that the folded edge portion can be firmly bonded.

[0047] Specifically, the synchronous paper sheet conveying and rolling mechanism includes a frame, a conveying component 120, a rolling component 130 and an adjusting component 140. The conveying component 120, the rolling component 130 and the adjusting component 140 are all arranged on the frame, and the conveying component 120 and the rolling component 130 are transmission connected. The conveying component 120 is used to convey the paper sheet 200, the rolling component 130 is used to roll the edge of the paper sheet 200 while the conveying component 120 is conveying the paper sheet 200, and the adjusting component 140 is used to adjust the clamping force of the conveying component 120 on the paper sheet 200 to improve the conveying effect of the paper sheet 200 and avoid damaging the paper sheet 200. It can also be used to adjust the spacing between the conveying component 120 and the rolling component 130 to accommodate paper sheets 200 of different sizes.

[0048] Please refer to Figure 4 and Figure 6The frame includes two symmetrically arranged wall panels 110, and the conveying assembly 120 includes two groups of conveying roller groups arranged between the two wall panels 110 and connected in transmission. The conveying roller group includes a driving shaft 122, a driven shaft 124, and a conveying belt 126 connected between the driving shaft 122 and the driven shaft 124. The two conveying belts 126 are used to clamp and drive the paper sheet 200 to move. The conveying roller group includes an upper conveying roller group and a lower conveying roller group stacked and arranged in a vertical direction, and the two driving shafts 122 of the upper conveying roller group and the lower conveying roller group are meshed and connected. The two ends of the driving shaft 122 and the driven shaft 124 are respectively connected to the two wall panels 110 for rotation. The driving shaft 122 of the lower conveying roller group is provided with a transmission gear 1222, and the transmission gear 1222 is externally connected to a driving member to serve as a power source of the paper synchronous conveying roller pressing mechanism. The conveyor belt 126 is connected by a pulley 128 disposed between the driving shaft 122 and the driven shaft 124. The conveyor belt 126 includes an upper conveyor belt 126 and a lower conveyor belt 126. The upper conveyor belt 126 and the lower conveyor belt 126 clamp the paper piece 200 and drive it to move. A support plate 114 is also arranged between the two wall panels 110. The support plate 114 is located in the middle of the lower conveyor belt 126, and a support groove 1142 is provided on its upper surface. The lower conveyor belt 126 is located in the support groove 1142 and its upper surface is flush with the upper surface of the support plate 114. Such an arrangement can keep the lower conveyor belt 126 horizontal, and prevent the lower conveyor belt 126 from falling and causing the paper piece 200 to bend. Of course, in other embodiments, the upper surface of the lower conveyor belt 126 can also be slightly higher than the upper surface of the support plate 114, so as to reduce the friction between the paper piece 200 and the support plate 114.

[0049] A plurality of roller pressing assemblies 130 are arranged near the conveying assembly 120 and are in transmission connection with the conveying roller group. The plurality of roller pressing assemblies 130 are sequentially arranged along the conveying path of the paper sheet 200 and the adjacent roller pressing assemblies 130 are meshed and linked to synchronously press the edge of the paper sheet 200. In the present embodiment, three groups of roller pressing assemblies 130 are provided and are arranged through one of the wall panels 110 to press one side of the paper sheet 200. Of course, according to actual needs, six groups of roller pressing assemblies 130 can also be provided, and the six groups of roller pressing assemblies 130 are evenly distributed on the two wall panels 110 to facilitate simultaneous pressing of both sides of the paper sheet 200, or other numbers of roller pressing assemblies 130, the specific number of which can be set according to needs and is not specifically limited here.

[0050] Please refer to Figure 5The roller pressing assembly 130 includes an active roller pressing group and a driven roller pressing group which are arranged on the upper surface and the lower surface of the paper sheet 200 and meshedly connected. The active roller pressing group is connected to the driving shaft 122 through a pulley structure. The active roller pressing group is driven to rotate by the driving shaft 122, and then the active roller pressing group drives the driven roller pressing group through meshing connection, so as to realize synchronous rolling of the upper and lower surfaces while conveying the paper sheet 200, improve the synchronization of conveying and rolling, and avoid tearing of the paper sheet 200.

[0051] The structures of the active roller pressing group and the driven roller pressing group are the same. The driven roller pressing group is arranged directly above the active roller pressing group. The structures of the active roller pressing group and the driven roller pressing group on the side close to the conveyor belt 126 are the same, and both include a roller pressing fixed cylinder 134 passing through the wall panel 110, a roller pressing wheel shaft 131 rotatably connected to the roller pressing fixed cylinder 134, and a roller pressing wheel 136 and a roller pressing gear 137 arranged on the side close to the conveyor belt 126 of the wall panel 110. Among them, a rolling space is formed between the two roller pressing wheels 136, which is used to roll the paper sheet 200 passing through the rolling space. The active roller pressing gear 1372 of the active roller pressing group is meshedly connected with the driven roller pressing gear 1374 of the driven roller pressing group, so that the driven roller pressing group can be driven to rotate by the active roller pressing group, so as to reduce the power source and improve the synchronization between the active roller pressing group and the driven roller pressing group.

[0052] The pulley structure includes a roller pulley 132 which is arranged on the roller wheel shaft 131 of the active roller group and is located on the side of the wall panel 110 away from the conveyor belt 126, a synchronous pulley 1224 arranged on the active shaft 122, and a synchronous belt 133 connected to the roller pulley 132 and the synchronous pulley 1224. The transmission ratio between the roller pulley 132, the synchronous pulley 1224 and the two roller gears 137 is 1:1, so that the transmission component 120 and the roller component 130 rotate synchronously.

[0053] In this embodiment, three groups of roller pressing assemblies 130 are arranged in sequence along the conveying direction of the paper sheet 200 and the adjacent roller pressing gears 137 are meshed and connected. The adjacent roller pressing gears 137 here refer to two adjacent roller pressing gears 137 in the conveying direction and the roller pressing gears 137 on the active roller pressing group and the driven roller pressing group located on the upper and lower sides of the paper sheet 200. The synchronous belt 133 on the roller pressing wheel shaft 131 is sequentially connected to the driving shaft 122 in transmission, so as to perform multiple rolling on the edge of the paper sheet 200 to improve the rolling effect. A tensioning wheel 135 is arranged between two adjacent roller pressing assemblies 130. The tensioning wheel 135 is rollingly connected to the synchronous belt 133 and is used to tension the synchronous belt 133 to improve the transmission efficiency.

[0054] Please refer to Figure 4 and Figure 6In this embodiment, the synchronous conveying and rolling mechanism of the paper sheet 200 further includes an end rolling group that is transmission-connected to the driven shaft 124. The end rolling group is disposed between the two driven shafts 124 and is transmission-connected to the driven shaft 124. The paper sheet 200 is rolled under the drive of the driven shaft 124 to ensure that the paper sheet 200 is rolled from the beginning of rolling until it is conveyed out of the conveying assembly 120, so as to improve the rolling effect of the paper sheet.

[0055] The end rolling group includes a pair of end rolling wheels 138, and the pair of end rolling wheels 138 are respectively arranged on a pair of driven shafts 124. The end rolling wheels 138 are fixedly sleeved on the driven shafts 124, and driven by the driven shafts 124 to synchronously rotate a pair of paper sheets 200 for rolling, avoiding the need for additional drive components, and at the same time, the driven shafts drive the end rolling wheels to rotate to improve the synchronization of the pair of end rolling wheels.

[0056] The adjustment assembly 140 includes a first adjustment member 142 and a second adjustment member 144 arranged on the frame. The first adjustment member 142 is rollingly connected to the conveyor belt 126 to adjust the clamping force of the two conveyor belts 126 on the paper sheet 200. The second adjustment member 144 is connected to the driven shaft 124 to adjust the distance between the driven shaft 124 and the driving shaft 122.

[0057] Please refer to Figure 7 In this embodiment, the first adjusting member 142 includes a roller 1422 rollingly connected to the conveyor belt 126 and a power member 1421 driving the roller 1422 to move in the direction of pressing the two conveyor belts 126. The roller 1422 includes a roller 1422 shaft and three bearings arranged on the rolling shaft. The power member 1421 is a cylinder. The outer ring of the bearing abuts against the upper conveyor belt 126 and can rotate under the drive of the upper conveyor belt 126. The cylinder drives the roller 1422 to move to adjust the pressure applied by the outer ring of the bearing to the upper conveyor belt 126, so as to adjust the clamping force of the upper conveyor belt 126 and the lower conveyor belt 126 on the paper sheet 200.

[0058] The frame also includes a connecting plate 112 connected between the two wall panels 110 and located above the conveying assembly 120, a first adjusting member 142 is disposed on the connecting plate 112, and a roller 1422 is disposed on the inner side of the conveyor belt 126. The connecting plate 112 is disposed correspondingly to the support plate 114, so that the roller 1422 is located directly above the support plate 114, and the roller 1422 is disposed on the inner side of the upper conveyor belt 126. The roller 1422 is driven by a cylinder to press the upper conveyor belt 126 down onto the lower conveyor belt 126, which not only ensures that the conveyor belt 126 is level, but also improves the clamping force of the conveyor belt 126 on the paper sheet 200.

[0059] In this embodiment, the first adjustment member 142 includes a mounting bracket connected between the power member 1421 and the roller 1422 and located above the transmission assembly 120, and the roller 1422 is elastically connected to the mounting bracket. The mounting bracket includes a mounting plate 1423 connected to the power member 1421 and a swing block 1424 mounted on the mounting plate 1423 and used to arrange the roller 1422. The swing block 1424 includes a connection end rotatably connected to the mounting plate 1423 and a movable end swinging relative to the connection end, and the movable end is elastically connected to the mounting plate 1423 and is configured to swing in a vertical plane. Since the first adjusting member 142 is arranged above the conveyor belt 126, the power member 1421 drives the roller 1422 to move in the vertical direction to tighten or loosen the conveyor belt. Therefore, by arranging a swing block 1424 whose movable end is elastically connected to the mounting plate 1423 in the vertical direction and whose movable end can swing in the vertical plane relative to the connecting end, after the power member 1421 drives the roller 1422 into place, the roller 1422 has an elastic movable amount in the vertical direction to avoid the rigid abutment between the roller 1422 and the conveyor belt 126. During the paper conveying process, the roller 1422 can make way to facilitate the paper conveying.

[0060] In the present embodiment, the pendulum block 1424 includes two movable ends extending at an acute angle from the connecting end to the distal end, a stop block 1425 is arranged between the two movable ends, and the movable end of the two movable ends close to the conveyor belt 126 is elastically connected to the stop block 1425. Specifically, the pendulum block 1424 is a V-shaped pendulum block 1424, and the V-shaped pendulum block 1424 includes a fixed portion rotatably connected to the mounting plate 1423 and two movable portions extending outward at an acute angle from the fixed portion, and the mounting plate 1423 is provided with a stop block 1425, and the two movable portions are respectively located on the upper and lower sides of the stop block 1425, wherein the movable portion located on the lower side is rotatably connected to the roller 1422, and is connected to the stop block 1425 by a spring 1426. With such arrangement, the movable portion located on the upper side can prevent the roller 1422 from being too low and thus affecting the conveyance of the paper sheet 200 . Meanwhile, the spring 1426 can ensure the elastic connection between the roller 1422 and the upper conveyor belt 126 , thereby improving the applicability of the conveyor belt 126 .

[0061] Please refer to Figures 1 to 3 In this embodiment, the second adjusting member 144 includes a mounting block 1242 sleeved on the driven shaft 124 and an adjusting bolt connected between the mounting block 1242 and the wall panel 110. The wall panel 110 is provided with a movable groove along the conveying direction of the paper sheet 200, the mounting block 1242 is located in the movable groove, the adjusting bolt is threadedly connected to the wall panel 110 and arranged in the conveying direction of the paper sheet 200 to be fixedly connected to the mounting block 1242, so as to adjust the distance between the driven shaft 124 and the driving shaft 122 to tighten the conveyor belt 126.

[0062] In this embodiment, the adjustment assembly 140 further includes a third adjustment member 146, which is arranged along the conveying direction of the vertical conveyor belt 126 and connected between the mounting block 1242 and the wall panel 110. The third adjustment member 146 has the same structure as the second adjustment member 144, except that the third adjustment member 146 is fixedly connected to the mounting block 1242 along the conveying direction of the vertical paper sheet 200 and is vertically adjustable and mounted on the wall panel 110 through an adjustment bolt to adjust the distance between the two driven shafts 124.

[0063] The adjustment assembly 140 further includes a fourth adjustment member 148, which is connected to the driven roller pressing group and drives the driven roller pressing group to approach or move away from the active roller pressing group. An adjustment slot is provided on the wall panel 110 in the vertical direction, and the roller pressing fixed cylinder 134 of the driven roller pressing group is arranged in the adjustment slot. The fourth adjustment member 148 is an adjustment cylinder, which is connected to the roller pressing fixed cylinder 134. The roller pressing wheel shaft 131 is driven to move by driving the roller pressing fixed cylinder 134 to move so as to adjust the distance between the two roller pressing wheels 136 to adapt to the rolling of paper sheets 200 of different sizes.
