Description
Technical Field
[0001] This utility model relates to the technical field of paper tube processing equipment, and more specifically, to a four-column paper tube press. Background Technology
[0002] Paper tubes, as a type of packaging container with a certain strength and environmental friendliness, are widely used in various fields such as food, chemical industry, and pharmaceuticals, and have a wide range of applications. In the traditional paper tube processing and production process, the bottom of the paper tube needs to be sealed to form a sealed paper tube and maintain the firmness and stability of the bottom of the paper tube.
[0003] Currently, the bottom sealing process for paper tubes can be done either entirely manually, where the paper tube is placed in a specific fixture for manual processing, or by placing the paper tube in a single forming press for bottom pressing. However, both methods require repositioning the paper tube during the forming process, which reduces the accuracy of repeated pressing and results in poor bottom sealing quality for some paper tubes. Summary of the Invention
[0004] The purpose of this application is to provide a four-column paper tube press, which solves the technical problem of integral fixed bottom sealing of paper tubes of various specifications and maintains the quality of the bottom sealing.
[0005] To solve the above-mentioned technical problems, the solution adopted in this application is as follows: Four-column paper tube press, including base.
[0006] Preferably, the base is equipped with a turntable rotation mechanism, which includes a turntable that is rotatably mounted, and four columns are evenly mounted coaxially around the turntable.
[0007] Preferably, a placement platform is coaxially mounted on the top of each column, the platform surface is horizontal, and a lifting platform is provided on the body of each column.
[0008] Preferably, a paper tube is fitted onto the column, with the unfolded side of the paper tube abutting against the lifting platform and the folded side of the paper tube located on the placement platform.
[0009] Preferably, an inner bottom pressure plate and an outer bottom pressure plate are respectively provided directly above two non-adjacent columns. The inner bottom pressure plate and the outer bottom pressure plate are respectively connected to the drive rod of the hydraulic cylinder, and the displacement direction of the inner bottom pressure plate and the outer bottom pressure plate is consistent with the length direction of the column.
[0010] Preferably, the lower surface of the outer bottom pressure plate is a plane, and the area and projected position of the plane correspond to the surface of the placement platform below.
[0011] Preferably, the inner bottom pressure plate includes a flat pressure plate and a sloping rounded edge.
[0012] Preferably, the upper part of the flat pressing table is fixedly connected to the hydraulic cylinder drive rod, the lower surface of the flat pressing table is a plane, and the area and projected position of the plane correspond to the table surface of the placement platform below.
[0013] Preferably, the edge of the planar pressing platform is fixedly provided with a beveled edge, the inner ring side of which is set as a bevel, and the surface of the bevel faces the center of the placement platform surface that is inclined downwards.
[0014] Preferably, the height of the inclined side is lower than the lower surface of the flat pressing table.
[0015] Preferably, the lifting platform includes a base.
[0016] Preferably, the base is slidably sleeved on the column, and the upper surface of the base abuts against the side of the paper tube along its length.
[0017] Preferably, the column body is provided with external threads, and a threaded rotating cylinder is threadedly fitted on the column. The threaded rotating cylinder is located below the base and abuts against the lower surface of the base.
[0018] Preferably, the threaded drum is also provided with bolts threaded laterally.
[0019] Preferably, the bottom of the bolt passes through the interior of the threaded cylinder, and the bottom of the bolt abuts against the surface of the column.
[0020] Preferably, the placement table is threaded onto the top of the column.
[0021] Preferably, the inner bottom pressure plate and the outer bottom pressure plate are engaged with the drive rod of the hydraulic cylinder.
[0022] Preferably, the four columns are arranged in an adjacent order as the first workstation, the second workstation, the third workstation, and the fourth workstation.
[0023] Preferably, when processing paper tubes, the processing sequence is the first station, the second station, the third station, and the fourth station.
[0024] The technical solution of this application has at least the following advantages and beneficial effects: This utility model features four columns with convertible workstations. By using a paper tube placement platform and a liftable lifting platform on the columns, the paper tube is placed on the columns and rotated in one piece to complete the bottom sealing work, maintaining the bottom sealing quality during paper tube forming and sealing, and matching paper tubes of different lengths for rapid bottom sealing.
[0025] This invention, by setting an inner bottom pressure plate with a beveled edge, can address the issue of slight outward folding of some inner folded edges of paper tubes during the process of flattening and bonding the inner bottom plate and folded edges. The beveled edge guides the outward folded edge to the projection of the lower surface of the inner flat pressure plate, facilitating the flat pressure plate to press the folded edge of the paper tube flat and bond it to the inner bottom plate on the placement platform, thus maintaining the sealing effect of the paper tube.

[0033] Example Please refer to Figures 1-4 This utility model provides a four-column paper tube press, including a base 1, on which a turntable rotation mechanism 2 is installed. The turntable rotation mechanism 2 includes an indexing plate 21 and a turntable 22. The indexing plate 21 is fixedly installed at the center of the base 1. The turntable 22 is coaxially fixedly installed on the rotating end of the indexing plate 21. Four columns 3 are fixedly installed on the turntable 22. The four columns 3 are evenly distributed around the center of the turntable 22. Each column 3 is also coaxially mounted on the top of a placement platform 4. The surface of the placement platform 4 is kept horizontal. A lifting platform 5 is also provided on the column body of each column 3.
[0034] Preferably, when the paper tube is placed on the column 3 (at this time, both sides of the paper tube are open, and one side of the paper tube has been folded inward to form a shape), the placement platform 4 and the lifting platform 5 on the four columns 3 can support and form four working positions respectively. In each working position, the unfolded side of the paper tube abuts against the lifting platform 5, and the folded side of the paper tube is located on the placement platform 4, so that the folded side of the paper tube can be sealed.
[0035] Furthermore, since paper tubes of different lengths require bottom sealing in actual production, please refer to [the relevant documentation / reference] for details. Figure 2 In this embodiment, the lifting platform 5 can be vertically raised and lowered on the column 3 to adjust the distance between the lifting platform 5 and the placement platform 4, thereby matching the length of paper tubes of different specifications, so that the folded edge of each paper tube can be located on the table surface of the placement platform 4, and there will be no situation where the distance of one side of the paper tube exceeds or is insufficient.
[0036] The lifting platform 5 includes a base 51, a threaded drum 52, and bolts 53.
[0037] Specifically, the base 51 is slidably sleeved on the column 3. The column 3 has external threads on its body and a threaded rotating cylinder 52 is threadedly sleeved on the column 3. The threaded rotating cylinder 52 is located below the base 51 and abuts against the lower surface of the base 51, while the paper tube is placed on the base 51.
[0038] When the height of the base 51 needs to be adjusted according to the length of the paper tube, the threaded drum 52 is manually rotated to move the base 51 upward. A bolt 53 is also threaded horizontally through the threaded drum 52. After the base 51 is adjusted to the specified height, the bolt 53 is manually rotated so that the bottom of the bolt 53 passes through the threaded drum 52 and abuts against the surface of the column 3, increasing the frictional resistance and thus fixing the threaded drum 52 and the base 51, reducing the spontaneous twisting of the threaded drum 52 caused by the processing vibration of the working position.
[0039] Furthermore, a top support frame 6 is installed on the base 1, and a hydraulic mechanism 7 is installed on the top support frame 6. The hydraulic drive end of the hydraulic mechanism 7 is connected to a pressure plate, which is used to press down and seal the bottom of the paper tube placed on the placement table 4.
[0040] The top support frame 6 includes a support column 61 and a top frame 62, and the hydraulic mechanism 7 includes a cylinder 71 and a hydraulic station 72.
[0041] Specifically, the two ends of the support column 61 are fixedly connected to the base 1 and the top frame 62, respectively. Two hydraulic cylinders 71 are fixedly installed on the top frame 62. Each hydraulic cylinder 71 is connected to a hydraulic station 72. The hydraulic station 72 controls the oil pressure inside the hydraulic cylinder 71 to drive the drive rod of the hydraulic cylinder 71 to extend and retract. The hydraulic station 72 is placed on the ground.
[0042] The inner bottom pressure plate 8 and the outer bottom pressure plate 9 are coaxially fixed on the drive rods of the two hydraulic cylinders 71 respectively. The inner bottom pressure plate 8 and the outer bottom pressure plate 9 are aligned vertically with the two non-adjacent columns 3 on the turntable 22. When the paper tube is sealed, the pressure plates above the two columns 3 will press down to seal the inner bottom and the outer bottom of the paper tube on the placement platform 4 respectively, thereby achieving the sealing of the paper tube.
[0043] Furthermore, in order to complete the sealing of the paper tube, this embodiment is provided with an inner bottom pressure plate 8 and an outer bottom pressure plate 9, which respectively press the inner bottom plate and the outer bottom plate of the paper tube. When pressing the inner bottom plate, the folded edge of the paper tube and the inner bottom plate are initially pressed flat and attached together. However, during this pressing process, the inner folded edge of the paper tube sleeved on the column 3 may be slightly turned outward due to the operator's handling operation. As a result, it is easy to be pressed outward by the inner bottom pressure plate 8 when flattening, thus failing to attach to the inner bottom plate and affecting the sealing effect of the paper tube.
[0044] To solve the above problems, please refer to Figure 3 The inner bottom pressure plate 8 includes a flat pressure table 81 and an inclined table. The flat pressure table 81 is fixedly connected to the drive rod of the hydraulic cylinder 71. The lower surface of the flat pressure table 81 is flat, and its area and projection position correspond to the table surface of the placement platform 4 below, so that the flat pressure table 81 perfectly matches one side of the paper tube after pressing down. A circular edge 82 of the inclined table is fixedly provided on the edge of the flat pressure table 81. The inner ring side of the circular edge 82 of the inclined table is set as an inclined edge. The surface of the inclined edge faces the center of the table surface of the placement platform 4 below, and the height of the inclined edge is lower than the lower surface of the flat pressure table 81. When the inner bottom pressure plate 8 presses down close to the placement platform 4, the surface of the inclined edge will contact the outward folded edge on the paper tube. Through the guidance of the inclined edge, the folded edge is guided to the projection of the lower surface of the inner flat pressure table 81, so that the flat pressure table 81 can press down the folded edge of the paper tube and flatten and fit it with the inner bottom plate on the placement platform 4.
[0045] For preferred options, please refer to [the provided text]. Figure 4 The four workstations on turntable 22 work together to complete the sealing of the paper tube, and the work of each workstation is different. The four workstations are set as the first workstation, the second workstation, the third workstation, and the fourth workstation in adjacent order. On the column 3 of the first workstation, the worker first places the cardboard (inner bottom plate) on the plane of the placement table 4 (the shape of the cardboard is consistent with the inner diameter cross-section of the paper tube), and then puts the paper tube on the column 3 so that the folded edge is close to the upper surface of the cardboard on the placement table 4. At this time, the turntable 22 rotates a quarter turn, and the column 3 of the first workstation rotates to the second workstation.
[0046] Preferably, on the column 3 located in the second station, the hydraulic cylinder 71 drives the inner bottom pressure plate 8 to press down, initially pressing the folded edge of the paper tube together with the cardboard on the placement table 4. The flat surface of the flat pressure table 81 maintains the initial flattening of the bottom of the paper tube. At this time, the turntable 22 rotates another quarter turn, and the column 3 of the second station rotates to the third station.
[0047] Preferably, on the column 3 located at the third station, the worker applies a layer of adhesive to the lower surface of another identical cardboard (outer bottom plate), and then places it on the flattened paper tube fold and inner bottom plate to adhere it, while maintaining the coaxial alignment of the cardboard and the paper tube. At this time, the turntable 22 rotates another quarter turn, and the column 3 of the third station rotates to the fourth station.
[0048] Preferably, on the column 3 at the fourth work station, the hydraulic cylinder 71 drives the outer bottom pressure plate 9 to press down. The lower surface of the outer bottom pressure plate 9 is flat, which can press the glued cardboard tightly onto the folded edge and inner bottom plate of the paper tube, squeeze out the air in the bonding surface, and push the glue in the bonding surface evenly to maintain the bonding effect. Then, after pressing down for a specified time, it separates from the paper tube, providing time for the glue on the cardboard to solidify, so that the paper tube can complete the bottom sealing work. At this time, the turntable 22 rotates another quarter turn, and the bottom-sealed paper tube on the column 3 at the fourth work station rotates to the first work station. The workers here take off the processed paper tube and put in the unsealed paper tube again, repeating the above work steps.
[0049] It is worth noting that in some embodiments, the placement platform 4 is threaded onto the top of the column 3, and the inner bottom pressure plate 8 and the outer bottom pressure plate 9 are both snapped onto the drive rod of the hydraulic cylinder 71, so that they can be disassembled and replaced with placement platforms 4 and pressure plates of different diameters, which is convenient for matching the bottom pressing work of paper tubes of different diameters.

Those skilled in the art will fully understand how to implement the technical solution of this utility model based on the above description.
