Description

Technical Field

[0001] This utility model relates to the field of crease-making equipment technology, specifically to a crease-making equipment structure for precise adjustment of crease depth. Background Technology

[0002] Crease equipment is commonly used for processing cardboard boxes or corrugated cardboard products. The crease line assembly is fixed to the bottom of the front pressure plate and forms a vertical cross layout with the paper feeding track to ensure that the cardboard completes the transverse crease operation during the transmission process. By applying pressure, the cardboard fiber structure undergoes plastic deformation to form a preset crease line, providing precise folding guidance for subsequent box forming. The crease-forming equipment uses a crease-forming wheel to apply downward pressure to the surface of the cardboard, forming creases on the cardboard surface. During this process, if the downward pressure is too great and the crease is too deep, it can easily damage the cardboard or corrugated cardboard, causing the crease to burst. Therefore, a crease device with a precise crease depth adjustment structure is needed to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a crease depth adjustment structure for a crease device, so as to solve the problem mentioned in the background art that the crease device is not convenient for restricting the position of the crease wheel.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a crease depth precision adjustment structure for a crease device, comprising a mounting base, a guide tube, and a sleeve. The bottom end of the mounting base is fixed with the guide tube, and the outer side of the guide tube is fitted with the sleeve. An electric push rod is installed inside the guide tube, and the bottom end of the electric push rod is fixedly connected to the bottom end inside the sleeve. A limit adjustment assembly is provided on the outer wall of the sleeve. The limit adjustment assembly includes a guide groove, a limit bolt, a connecting hole, a scale groove, a limit ring, a locking hole, and a locking bolt. A guide groove is provided on the left side surface of the sleeve, and a limit bolt is inserted inside the guide groove. A connecting hole is provided at the bottom end of the left side surface of the guide tube, and the right side of the limit bolt extends into the connecting hole. Scale grooves are provided at both ends of the guide groove. A limit ring is provided at the top end of the outer side of the sleeve, and a locking hole is provided on the right side of the limit ring. A locking bolt is threaded into the locking hole.

[0005] As a further technical solution of this utility model, the surface of the limiting bolt is provided with external threads, and the interior of the connecting hole is provided with internal threads.

[0006] As a further technical solution of this utility model, a plurality of scale grooves are provided at both ends of the guide groove, and the plurality of scale grooves are distributed at equal intervals.

[0007] As a further technical solution of this utility model, a wheel frame is installed at the bottom end of the sleeve, and an indentation wheel is movably installed inside the wheel frame.

[0008] As a further technical solution of this utility model, a cleaning platform is provided at the top of the inside of the wheel frame, a cleaning cotton is fixed at the bottom of the cleaning platform, and fixing bolts are installed at both ends of the bottom of the cleaning platform.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a limiting ring, the limiting ring is sleeved on the outside of the sleeve and can move up and down along the outside of the sleeve to adjust the height position of the limiting ring. After adjustment, the locking bolt is tightened to fix the position. When the electric push rod pushes the sleeve down along the guide tube, the limiting ring moves down synchronously and contacts the protruding limiting bolt, which can limit the downward movement of the sleeve. By controlling the height position of the limiting ring on the outside of the sleeve, the downward movement position of the sleeve and the lower indentation wheel is indirectly limited, thus realizing the limiting control function of the downward movement depth of the indentation wheel of the crease device. The device is equipped with a cleaning cotton pad and a cleaning table. The cleaning cotton pad is installed at the top of the inner side of the wheel frame by a fixing bolt. When the crease wheel rotates, it comes into contact with the cleaning cotton pad. The cleaning cotton pad helps to clean the crease wheel, thus realizing the cleaning function of the crease wheel of the crease device. By setting a limiting wheel, a pressure rod, and a bottom limiting wheel, which are elastically connected with the assistance of a spring, the limiting wheel is located at the front and rear ends of the wheel frame. The limiting wheel is located below the creasing wheel. When it moves down, it moves one step ahead of the creasing wheel and contacts the surface of the cardboard. The limiting wheel and the spring work together to press on the surface of the cardboard, which can help limit the position of the cardboard and realize the auxiliary limiting function when the creasing device is used.

[0015] 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.

[0016] Please see Figure 1-4 This utility model provides an embodiment of a crease depth precision adjustment structure for a crease device, comprising a mounting base 1, a guide tube 2, and a sleeve 3. The bottom end of the mounting base 1 is fixed with the guide tube 2, and the sleeve 3 is sleeved on the outside of the guide tube 2. An electric push rod 4 is installed inside the guide tube 2, and the bottom end of the electric push rod 4 is fixedly connected to the bottom end inside the sleeve 3. A wheel frame 5 is installed at the bottom end of the sleeve 3, and an indentation wheel 6 is movably installed inside the wheel frame 5. A limit adjustment assembly is provided on the outer wall of the sleeve 3, and the limit adjustment assembly includes a guide groove 7, a limit bolt 8, a connecting hole 9, a scale groove 10, a limit ring 11, a locking hole 12, and a locking mechanism. A guide groove 7 is provided on the left side surface of the sleeve 3, and a limiting bolt 8 is inserted inside the guide groove 7. A connecting hole 9 is provided at the bottom end of the left side surface of the guide tube 2. The right side of the limiting bolt 8 extends into the interior of the connecting hole 9. The surface of the limiting bolt 8 is provided with external threads, and the interior of the connecting hole 9 is provided with internal threads. Both ends of the guide groove 7 are provided with scale grooves 10. Several scale grooves 10 are provided at both ends of the guide groove 7, and the several scale grooves 10 are distributed at equal intervals. A limiting ring 11 is provided at the top of the outer side of the sleeve 3. A locking hole 12 is provided on the right side of the limiting ring 11, and a locking bolt 13 is connected to the internal thread of the locking hole 12. Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, during use, the limiting ring 11 can move up and down along the outside of the sleeve 3. With the assistance of the scale groove 10, the distance between the limiting ring 11 and the limiting bolt 8 can be adjusted. This distance is the length that the indentation wheel 6 can move down. By adjusting the height of the limiting ring 11, the degree of downward movement of the indentation wheel 6 can be indirectly adjusted. A cleaning platform 14 is provided at the top inside the wheel frame 5. A cleaning cotton 15 is fixed at the bottom of the cleaning platform 14. Fixing bolts 16 are installed at both ends of the bottom of the cleaning platform 14. Specifically, such as Figure 1 and Figure 4 As shown, when in use, the creasing wheel 6 rolls on the surface of the cardboard. When performing the crease operation, the rolling creasing wheel 6 continuously contacts the cleaning cotton 15 at the top of the inner side of the wheel frame 5. With the help of the cleaning cotton 15, the creasing wheel 6 can be cleaned. Both ends of the wheel frame 5 are equipped with side platforms 17. The side platform 17 has a sliding groove 18 inside. A pressure rod 19 is movably installed inside the sliding groove 18. A spring 20 is installed at the top of the outer side of the pressure rod 19. A top platform 21 is fixed at the top of the pressure rod 19. A limit wheel 22 is movably installed at the bottom of the pressure rod 19. Specifically, such as Figure 1 and Figure 4 As shown, when the indentation wheel 6 moves down, the limiting wheels 22 on both sides press against the surface of the cardboard first. The limiting wheels 22 cooperate with the spring 20 to elastically press against the surface of the cardboard, which can help limit the cardboard.

[0017] Working principle: During use, the cardboard moves along the underside of the creasing roller 6 with the assistance of the conveying equipment. Activating the electric push rod 4 drives the sleeve 3 to move downwards along the guide tube 2, causing the creasing roller 6 on the bottom side to press against the surface of the cardboard. During the cardboard's movement, the creasing roller 6 rolls on the cardboard surface, forming creases to assist in subsequent processing. The pressure rod 19 and the bottom limiting roller 22 are elastically connected with the assistance of the spring 20, located at the front and rear ends of the wheel frame 5. The limiting roller 22 is located below the creasing roller 6; when moving downwards, it contacts the cardboard surface one step ahead of the creasing roller 6. The limiting roller 22, in conjunction with the spring 20, presses against the cardboard surface, assisting in the paper's alignment. The board position is limited to help increase the stability of the crease. The crease roller 6 rolls on the surface of the cardboard. During the crease operation, the rolling crease roller 6 continuously contacts the cleaning cotton 15 at the top of the inner side of the roller frame 5. The cleaning cotton 15 can help clean the crease roller 6. The distance between the limiting ring 11 and the limiting bolt 8 is the length that the crease roller 6 can move down. The limiting ring 11 can move up and down along the outside of the sleeve 3. With the assistance of the scale groove 10, the distance between the limiting ring 11 and the limiting bolt 8 can be adjusted. By adjusting the height of the limiting ring 11, the downward movement of the crease roller 6 is limited to avoid the crease being too deep and affecting the crease quality.
