Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of corrugated paper cutting, and particularly relates to a device for cutting corrugated cardboard to a fixed length. Background Technique
[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper sandwich and one layer of cardboard. It has high mechanical strength and can withstand collisions and drops during handling. The actual performance of corrugated cardboard depends on three factors: the characteristics of the core paper and cardboard, and the structure of the carton itself; there are mainly two methods for corrugated paper cutting: cross-cutting and longitudinal cutting; Cross-cutting: Cross-cutting is to cut the corrugated paper by the way of a flick knife, like scissors; Longitudinal cutting: Longitudinal cutting is to use a very thin circular knife and cut the corrugated paper by the high-speed rotation of the knife; Both of these methods are applicable to corrugated paper with 3 layers, 5 layers or 7 layers.
[0003] In the prior art, the fixed-length cutting of corrugated paper is usually carried out by means such as precise control of the moving distance of the corrugated cardboard to cut the corrugated cardboard to a fixed length. However, in this way, there is only one cutting part, and only one section of corrugated cardboard can be cut each time. After cutting, the corrugated cardboard needs to be moved, and the corrugated cardboard cannot be cut into multiple sections of cardboard with a fixed length at the same time. Content of the Utility Model
[0004] Aiming at the problems raised in the above background technique, the purpose of the present utility model is to provide a device for cutting corrugated cardboard to a fixed length to solve the problems raised in the above background technique.
[0005] To achieve the above technical purpose, the technical solution adopted by the present utility model is as follows:
[0006] A device for cutting corrugated cardboard to a fixed length includes a workbench. Support frames are provided on both the front and rear sides of the workbench. A connecting rod is fixedly connected between the support frames. A plurality of translation rods are slidably connected between the two connecting rods. A cutting assembly is assembled and connected to the lower side of the translation rods. A first telescopic cylinder is assembled and connected between the rear support frame on one side of the output end of the workbench and the translation rod on one side of the output end. A second telescopic cylinder is assembled and connected between adjacent two translation rods. A positioning assembly for positioning the corrugated cardboard is provided between adjacent two translation rods.
[0007] Preferably, the number of the translation rods is two.
[0008] Preferably, the cutting assembly includes a third telescopic cylinder. An electric slide rail is assembled and connected between the third telescopic cylinder and the translation rod. A cutting machine is assembled and connected to the output shaft of the third telescopic cylinder.
[0009] Preferably, the positioning component includes a connecting frame, which includes three sliding bars slidably connected to the two translation bars and a connecting plate fixedly connected to the lower side of the middle of the sliding bars. A positioning plate is provided on the lower side of the connecting plate, and a fourth telescopic cylinder is assembled and connected between the positioning plate and the connecting plate.
[0010] Preferably, vertical sliding rods are fixedly connected to the upper sides of both ends of the connecting plate, and the sliding rods are slidably connected in through holes formed in the translation bars and the connecting plate.
[0011] Preferably, a positioning member is fixedly connected to the upper side of the output end of the workbench, and the positioning member is a positioning plate flush with the connecting frame.
[0012] Preferably, first limit blocks are provided at both ends of the sliding bar, and second limit blocks are provided on both sides of the sliding bar on the connecting plate.
[0013] The utility model has the following advantages compared with the prior art:
[0014] The utility model is ingeniously designed. By making the working lengths of the first telescopic cylinder and the second telescopic cylinder the same, the distance between the support frame and the translation bar is the same as the distance between the two translation bars. When one end of the corrugated cardboard is moved to a position flush with the support frame on the upper side of the workbench and the output end side, the two cutting machines can perform fixed-length cutting on the corrugated cardboard, cutting the corrugated cardboard into two pieces of the same length, thereby improving the cutting efficiency.
[0015] The utility model has strong adaptability. At the same time, when the lengths output by the output ends of the first telescopic cylinder and the second telescopic cylinder change, the cutting length of the corrugated cardboard also changes, so that corrugated cardboard of different lengths can be cut according to the usage requirements.
[0016] The utility model designs a positioning component between the two translation bars. The positioning component is fully utilized. The cutting machines work on both sides of the positioning component, and the positioning component will not affect the work of the cutting machines. At the same time, during the cutting work, the corrugated cardboard can also be positioned and will not be affected by the cutting work, so as to have a better cutting effect.

[0030] In order to enable those skilled in the art to better understand the present utility model, the technical solution of the present utility model will be further described below with reference to the drawings and embodiments.
[0031] As Figures 1-4 shown, a fixed-length corrugated cardboard cutting device includes a workbench 1. Support frames 2 are provided on both the front and rear sides of the workbench 1. Connecting rods 21 are fixedly connected between the support frames 2 on the same side. A plurality of translation rods 3 are slidably connected to the two connecting rods 21. A cutting assembly 4 is assembled and connected to the lower side of the translation rod 3. A first telescopic cylinder 51 is assembled and connected between the rear support frame 2 on one side of the output end of the workbench 1 and the translation rod 3 on one side of the output end. A second telescopic cylinder 52 is assembled and connected between two adjacent translation rods 3. A positioning assembly 6 for positioning the corrugated cardboard is provided between two adjacent translation rods 3.
[0032] Adopting the technical solution of this embodiment, the corrugated board is conveyed from the input side of the workbench to the workbench 1. The corrugated board moves to the position flush with the ears of the support frame and stops moving. The translation rod 3 is used to drive the cutting assembly 4 to move. When the first telescopic cylinder 51 and the second telescopic cylinder 52 work, the translation rod 3 slides along the direction of the connecting rod 21. The working lengths of the first telescopic cylinder 51 and the second telescopic cylinder 52 are controlled by a program, and at the same time, they are of the same size and model, so that the cutting lengths of the cutting assembly 4 for the corrugated board are the same. The first telescopic cylinder 51 controls the distance between the translation rod 3 adjacent to the support frame 2 and the support frame 2. At the same time, the translation rod 3 drives the adjacent translation rod 3 to move, thereby driving the cutting assembly 4 to move. When the working lengths of the first telescopic cylinder 51 and the second telescopic cylinder 52 are the same, the working lengths of the first telescopic cylinder 51 and the second telescopic cylinder 52 are realized through the cooperation of a displacement sensor and a program control, which has been mature in the prior art, so no detailed explanation will be given here. Thus, the distance between the support frame 2 and the adjacent translation rod 3 is equal to the distance between the two adjacent translation rods 3, and the cutting lengths of the cutting assembly for the corrugated board are the same. The positioning assembly 6 is used to position the corrugated board to prevent the corrugated board from moving during the cutting of the corrugated board.
[0033] Refer to Figure 1 : The number of translation rods 3 is two.
[0034] Refer to Figure 1 : The cutting assembly 4 includes a third telescopic cylinder 41. An electric slide rail 42 is assembled and connected between the third telescopic cylinder 41 and the translation rod 3. The output shaft of the third telescopic cylinder 41 is assembled and connected with a cutting machine 43.
[0035] In this embodiment, the third telescopic cylinder 41 is used to control the descent of the cutting machine 43, so that the cutting machine 43 can contact the corrugated board and cut the corrugated board.
[0036] Refer to Figure 1 and 3 : The positioning assembly 6 includes a connecting frame 61. The connecting frame 61 includes three sliding strips 611 slidably connected to the two translation rods 3 and a connecting plate 612 fixedly connected to the lower side of the middle part of the sliding strips 611. A positioning plate 62 is provided on the lower side of the connecting plate 612. A fourth telescopic cylinder 63 is assembled and connected between the positioning plate 62 and the connecting plate 612.
[0037] In this embodiment, the connecting frame 61 is used to connect to the positioning plate 62. At the same time, when the distance between the two translation rods 3 changes, the sliding strips 611 can slide in the through holes opened in the translation rods 3. The connecting plate 612 fixes the three sliding strips 611 to make the three sliding strips 611 move simultaneously. The fourth telescopic cylinder 63 controls the descent of the positioning plate 62 to position the corrugated board with the positioning plate 62.
[0038] Refer to Figure 3On the upper sides of both ends of the connecting plate 612, there are vertically fixed sliding rods 64, and the sliding rods 64 are slidably connected in the through holes formed in the translation rod 3 and the connecting plate 612.
[0039] In this embodiment, when the positioning plate 62 moves upward, the sliding rod 64 moves within the through holes formed in the translation rod 3 and the connecting plate 612.
[0040] Refer to Figure 2 On the upper side of the output end of the workbench 1, there is a fixedly connected positioning member 7, and the positioning member 7 is a positioning plate flush with the connecting frame 61.
[0041] In this embodiment, the positioning member 7 positions the initial position of the corrugated cardboard, and the conveying component on the input side of the workbench moves the initial position of the corrugated cardboard to the position of the positioning member 7.
[0042] Refer to Figure 1 and 3 At both ends of the sliding strip 611, there are first limit blocks 613, and on both sides of the connecting plate 612, there are second limit blocks 614 for the sliding strip 611.
[0043] In this embodiment, the first limit block 613 is used to prevent the sliding strip 61 from sliding out of the translation rod 3, and the second limit block 614 is used to prevent the positioning plate 62 from sliding to a position where it contacts the cutting machine 43.
[0044] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in this field. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.
[0045] The above embodiments only exemplarily illustrate the principles and effects of the present utility model, rather than limiting the present utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
