Abstract
Description
Technical Field
[0001] The utility model relates to paper processing equipment, in particular to a paper towel machine. Background Art
[0002] The working surface of the paper guide roller of the existing paper towel machine can meet the functional requirements of paper stacking when cutting the two ends of small paper products without trimming the products. However, according to market demand, different products require small paper products of different lengths, so the base paper needs to be trimmed when the paper is transferred by the paper towel machine. The paper guide roller of the existing paper towel machine guides the base paper, and trimming knives are installed on both sides of the paper guide roller to cut the base paper. However, when the paper width is less than the length of the bottom roller, the length of the working surface of the paper guide roller is greater than the width of the base paper, and problems such as paper jams and paper dragging will occur during the cutting process, causing the equipment to fail to operate normally. However, if the length of the paper guide roller is shortened, base paper with a larger width cannot be guided out. Therefore, the existing paper towel machine cannot adapt to the trimming requirements of various base paper widths. Utility Model Content
[0003] Purpose of the utility model: The purpose of the utility model is to provide a paper towel machine that is suitable for trimming the base paper of various widths.
[0004] Technical solution: The utility model provides a paper towel machine, comprising a frame and a paper feed roller and a trimming knife installed on the frame; movable rollers for extending the paper feed roller are provided at both ends of the paper feed roller, the movable rollers are slidably installed at both ends of the paper feed roller, and positioning bolts are provided on the movable rollers; axially symmetrical mounting shafts are installed on both sides of the frame, and the trimming knife is slidably installed on the mounting shafts, and a nut for fixing the trimming knife is also provided on the mounting shaft.
[0005] Furthermore, the movable roller is composed of two semicircular rings, and the semicircular rings are provided with screw holes that cooperate with positioning bolts.
[0006] Furthermore, a rotating shaft is transversely mounted on the frame, the paper guiding roller is fixedly mounted on the rotating shaft, and the movable roller is detachably mounted on the rotating shaft via positioning screws.
[0007] Furthermore, the trimming knife is tangent to the roller surfaces of the paper feeding roller and the movable roller at the same time.
[0008] Furthermore, a collection pipe for collecting waste paper is arranged below the trimming knife, and a funnel-shaped collection port is installed above the collection pipe.
[0009] Furthermore, a locking sleeve is provided between the collecting pipe and the collecting port.
[0010] Furthermore, a fixing frame is fixedly connected to the frame, and the fixing frame is fixedly connected to the locking sleeve.
[0011] Furthermore, the movable roller and the paper feeding roller have the same diameter.
[0012] Beneficial effects: Compared with the prior art, the utility model has the following advantages: the position of the movable roller can be adjusted and matched with the paper feed roller to adapt to base paper of different widths, and no jamming occurs during trimming, thereby improving the efficiency of trimming. BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a schematic diagram of the overall structure of the utility model. DETAILED DESCRIPTION
[0014] The technical solution of the utility model is further described below in conjunction with the accompanying drawings.
[0015] like Figure 1 As shown, the paper towel machine of the utility model comprises a frame 1, a paper feed roller 2, a movable roller 3 and a trimming knife 4, a rotating shaft 5 is horizontally installed on the frame 1, and both ends of the rotating shaft 5 are rotatably connected to the frame 1 through bearings; the paper feed roller 2 is sleeved in the middle of the rotating shaft 5 and is fixedly connected to the rotating shaft 5; the movable rollers 3 are symmetrically installed at both ends of the paper feed roller 2; the movable roller 3 consists of two semicircular rings, screw holes are provided on the semicircular rings, and are fixedly installed on the rotating shaft 5 with fixing devices such as screws or bolts, and the diameter of the movable roller 3 is consistent with that of the paper feed roller 2.
[0016] The frame 1 is also symmetrically provided with mounting shafts 6 on both sides, and the mounting shafts 6 are perpendicular to the sides of the frame 1, and the mounting shafts 6 are provided with threads, and a through hole is provided in the middle of the trimming knife 4 to match the mounting shaft 6, and fixing nuts for fixing the position of the trimming knife 4 are provided at the front and rear of the trimming knife 4. When the trimming knife 4 is moved to a suitable position, the fixing nut is screwed in from the end of the mounting shaft 6 to fix the position of the trimming knife 4. The trimming knife 4 is tangent to the movable roller 3 and the paper feed roller 2 at the same time. A waste collection pipe 7 is provided below each trimming knife 4, and a funnel-shaped collection port 8 is installed above the collection pipe 7. The collection pipe 7 and the collection port 8 are fixedly connected by a locking sleeve 9, and the locking sleeve 9 is fixedly installed on the fixing frame 10, and the fixing frame 10 is fixedly installed on the frame 1, and the end of the collection pipe 7 is connected to the waste paper recycling box.
[0017] In the present application, the length of the paper feed roller 2 is 1145 mm, and the length of the movable roller 3 is 10-150 mm. In the present application, a 25 mm movable roller 3 is selected. The maximum distance from the contact to the separation of the movable roller 3 with the paper feed roller 2 is 10 mm. When the output paper length is required to be less than or equal to 1145 mm, the paper feed roller 2 is directly used to guide the base paper.
[0018] When it is necessary to export base paper exceeding 1145 mm, the movable rollers 3 on both sides can be slid toward the middle to splice the two movable rollers 3 and the paper feeding roller 2 together, so that the running range of the base paper can be expanded to 1145 mm + 150 mm * 2 = 1445 mm base paper.
[0019] When base paper larger than 1165 mm comes over and output paper of 1145 mm is needed, the trimming knife 4 is moved along the mounting shaft 6 until it is tangent to the end face of the paper feed roller 2, and then fixed on the mounting shaft 6 by bolts. The opening diameter of the funnel-shaped collecting port 8 is larger than 10 mm. When the base paper moves forward through the paper feed roller 2, the trimming knife 4 trims and cuts both sides of the base paper, and the waste paper enters the collecting tube 7 through the collecting port 8 to obtain output paper of 1145 mm length.
[0020] When 1155mm output paper is required, measure the distance, determine that the appropriate length is left, fix the position of the trimming knife 4, and then cut; in this process, both movable rollers 3 can be moved, or only one of the movable rollers 3 can be moved, and it is only necessary to reserve a length of 1155mm. For example, select an movable roller 3 with a length of 10mm, move the right movable roller 3 to fit the paper feed roller 2, and then fix the movable roller 3. At this time, the right trimming knife 4 is fixedly installed on the outside of the right movable roller 3, and the left trimming knife 4 is installed on the outside of the paper feed roller 2. If longer output paper is required, the movable roller 3 of appropriate length can be selected as needed, and the positions of the movable roller 3 and the trimming knife 4 can be adjusted to reserve the required length of the output paper for cutting.
