Description

Technical Field

[0001] This utility model relates to the field of paper packaging box production, specifically to an edge trimming device for a paper packaging box production line. Background Technology

[0002] Paper packaging boxes are paper boxes used to package various goods. They are usually supported by corrugated cardboard or other types of cardboard. During the cardboard production process, the edges of the cardboard will have some extra corners. The edges of the cardboard that have not been trimmed may have sharp burrs, which need to be removed.

[0003] The publication number CN219988591U discloses a de-edge removal device for a paper packaging box production line, including a de-edge cutting table, a conveying structure and a de-edge cutting structure. An electric track is fixed in the center of the de-edge cutting table, and there are mounting frames and movable plates on both sides of the electric track.

[0004] The aforementioned edge trimming device increases the contact area between the bottom surface of the cardboard and the conveyor belt, thereby increasing the friction between the cardboard and the conveyor belt and limiting the movement of the cardboard. However, when producing packaging boxes of different sizes, the length of the edges and corners that need to be removed from the cardboard varies, making it inconvenient to adjust the length of the edge and corner cutting. The cardboard is also prone to shifting during cutting, making it inconvenient to press and transmit. Utility Model Content

[0005] The purpose of this utility model is to provide an edge trimming device for a paper packaging box production line to solve the technical problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An edge-trimming device for a paper packaging box production line includes two supports, a first conveyor belt installed between the two supports, an adjustment mechanism installed on the top of the two supports, and a transmission mechanism installed on the top of the first conveyor belt. The adjustment mechanism includes a fixed plate and a support plate. The support plate is fixedly installed on one side of one of the supports, and the fixed plate is fixedly installed on the top of the other support. A cutting machine is installed in the center of the top of the support plate. Positioning frames are fixedly installed at both ends of the top of the support plate. Two hydraulic cylinders are installed on the outer side of the fixed plate. The telescopic rods of the hydraulic cylinders are fixedly installed with the same baffle. Fixed frames are fixedly installed on the inner side of the baffle and the bottom of the two positioning frames. A second conveyor belt is installed at the bottom of the fixed frames.

[0008] Preferably, a cutting groove is provided between the middle of the support plate and the bracket, and the cutting blade of the cutting machine is located in the cutting groove.

[0009] Preferably, the baffle is located directly above the first conveyor belt, and there is a gap between the baffle and the first conveyor belt.

[0010] Preferably, the rollers at both ends of the second conveyor belt are connected to the fixed frame via bearings, and the second conveyor belt drives in the opposite direction to the first conveyor belt.

[0011] Preferably, the transmission mechanism includes a motor and two transmission rods. The motor is mounted on the outer side of the fixed plate near the front end. The two transmission rods are respectively movably mounted between the fixed plate and two positioning frames. Positioning shafts are installed on both ends of the transmission rods, located on one of the second conveyor belt rollers.

[0012] Preferably, the transmission rod has a rectangular cross-section and is fixedly connected to the output shaft of the motor.

[0013] Preferably, the transmission rod passes through the inside of the roller of the second conveyor belt and is movably connected, while the roller of the second conveyor belt located inside the baffle is located outside the transmission rod and is slidably disposed.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1) This edge trimming device, by setting an adjustment mechanism, allows the baffle to slide by extending and retracting the hydraulic cylinder telescopic rod, so that one end of the cardboard slides against the inner side of the baffle, which facilitates the adjustment of the length of the cardboard edge cutting, so that the length of each cardboard edge cut is equal. The cardboard is pressed and conveyed by two second conveyor belts to prevent it from shifting during cutting.

[0016] 2) This edge-removing device, by setting a transmission mechanism, drives two second conveyor belts to rotate, which can press the cardboard while conveying it synchronously. By sliding the rollers of the second conveyor belts, the second conveyor belts can be adjusted to any position for continuous transmission, so as to facilitate the adaptation and adjustment of the baffle.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1

[0023] Combination Figures 1-3 A paper packaging box production line edge trimming device includes two supports 1, a first conveyor belt 2 installed between the two supports 1, an adjustment mechanism 3 installed on the top of the two supports 1, and a transmission mechanism 4 installed on the top of the first conveyor belt 2.

[0024] See Figure 2 Furthermore, the adjusting mechanism 3 includes a fixed plate 5 and a support plate 6. The support plate 6 is fixedly installed on one side of one of the brackets 1, and the fixed plate 5 is fixedly installed on the top of the other bracket 1. A cutting machine 7 is installed in the center of the top of the support plate 6. Positioning frames 8 are fixedly installed at both ends of the top of the support plate 6. Two hydraulic cylinders 9 are installed on the outside of the fixed plate 5. The same baffle 10 is fixedly installed at the end of the telescopic rod of the hydraulic cylinder 9. Fixed frames 11 are fixedly installed on the inside of the baffle 10 and at the bottom of the two positioning frames 8. A second conveyor belt 12 is installed at the bottom of the fixed frame 11.

[0025] A cutting groove is provided between the middle of the support plate 6 and the bracket 1. The cutting blade of the cutting machine 7 is located in the cutting groove. The excess corners of the paper packaging box are cut off by the cutting blade of the cutting machine 7.

[0026] The baffle 10 is located directly above the first conveyor belt 2. There is a gap between the baffle 10 and the first conveyor belt 2. The gap reduces the friction between the first conveyor belt 2 and the baffle 10. The baffle 10 is used to position the cutting length of the cardboard.

[0027] The rollers at both ends of the second conveyor belt 12 are connected to the fixed frame 11 by bearings. The second conveyor belt 12 has the opposite transmission direction to the first conveyor belt 2. The cardboard is pressed and conveyed by the second conveyor belt 12 to avoid deviation when cutting the corners.

[0028] Specifically, the hydraulic cylinder 9 drives the baffle 10 to slide laterally, so as to adjust the length of the cardboard corner cutting. The cardboard is attached to the baffle 10, and the second conveyor belt 12 presses the cardboard and conveys it backward. The cutting blade of the cutting machine 7 cuts off the corner of the cardboard.

[0029] Example 2

[0030] See Figure 3 Furthermore, based on Embodiment 1, the transmission mechanism 4 includes a motor 13 and two transmission rods 14. The motor 13 is installed on the outer side of the fixed plate 5 near the front end. The two transmission rods 14 are respectively movably installed between the fixed plate 5 and the two positioning frames 8. Positioning shafts 15 are installed on both ends of the transmission rods 14 and located at one of the second conveyor belt 12 rollers.

[0031] The cross-section of the transmission rod 14 is rectangular. The transmission rod 14 is fixedly connected to the output shaft of the motor 13. The transmission rod 14 rotates through the motor 13 and drives the two second conveyor belts 12 to rotate simultaneously.

[0032] The transmission rod 14 passes through the inside of the roller of the second conveyor belt 12 and is movably connected. The roller of the second conveyor belt 12 located inside the baffle 10 is located outside the transmission rod 14 and is slidably arranged. By sliding the roller of the second conveyor belt 12, the corresponding second conveyor belt 12 can be adjusted to any position for transmission.

[0033] Specifically, during the sliding process of the baffle 10, the roller of the second conveyor belt 12 inside the baffle 10 slides outside the transmission rod 14. The transmission rod 14 is rotated by the motor 13, which in turn drives the two second conveyor belts 12 to rotate simultaneously, so as to facilitate the adaptation, adjustment and transmission of the baffle 10 and the second conveyor belt 12.

[0034] In actual operation, the cardboard used for paper packaging box production is placed on the first conveyor belt 2 in sequence, and the excess edges and corners of the cardboard are cut off by the cutting blade of the cutting machine 7.

[0035] During positioning, two hydraulic cylinders 9 are activated simultaneously, causing the extension rods of the hydraulic cylinders 9 to slide the baffle 10 laterally, thereby adjusting the length of the cardboard to be cut. The cardboard is driven on the first conveyor belt 2 and slides on one side of the baffle 10. The cardboard is pressed and driven by the two second conveyor belts 12 to prevent it from shifting during cutting.

[0036] When the pressing transmission is performed, the motor 13 is started and the transmission rod 14 drives the two second conveyor belts 12 to rotate simultaneously, so that the transmission speed of the outer surface of the two second conveyor belts 12 is consistent with the transmission speed of the first conveyor belt 2. During the adjustment of the baffle 10, the roller of the second conveyor belt 12 inside the baffle 10 slides outside the transmission rod 14, and the second conveyor belt 12 is continuously driven by the transmission rod 14.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
