Description

An automatic web guiding device for cardboard production Technical Field

[0001] This utility model belongs to the field of paperboard production technology, and in particular relates to an automatic correction device for paperboard production. Background Technology

[0002] During the production of cardboard, raw material boards need to be cut according to design requirements to obtain the required dimensions. When the cardboard is conveyed and cut on the assembly line, the cardboard may deflect on the conveyor belt. When the deflected cardboard is conveyed to the cutting part for cutting, it will cause the cut shape of the cardboard to be deviated. After the cardboard is conveyed to the cutting part, manually correcting it can result in hand injuries from the cutting part. In addition, manual correction is ineffective and cannot completely align the cardboard with the required cutting position.

[0003] To address these issues, we provide an automatic alignment device for cardboard production. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic alignment device for cardboard production. This device involves installing an edge-limiting component above the conveyor belt, with two side plates fixedly mounted on either side of the conveyor belt. Guide rods on one side of the two push plates in the edge-limiting component slide through the side plates. Moving one push plate pushes the cardboard on the conveyor belt against the surface of the other push plate, thus aligning the cardboard on the conveyor belt. By adjusting the distance between one push plate and the side plate and fixing the push plate, the cardboard, when passing the push plate on the conveyor belt, is pushed and pressed against the surface by the other push plate. This allows the edge-limiting component to adjust the distance between the push plate and the side plate according to different cardboard sizes, thereby enabling the alignment of cardboard of different sizes.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an automatic correction device for cardboard production, including a conveyor belt and a side-limiting component. The side-limiting component includes two side plates, two push plates, and two top-edge assemblies.

[0009] The present invention is further configured such that a push cylinder is installed on the side plate of the conveyor belt away from the adjusting screw. The push cylinder is installed on the side plate away from the adjusting screw, and the telescopic end of the push cylinder passes through the side plate. The telescopic end of the push cylinder is fixedly installed on the push plate near the push cylinder.

[0010] The present invention is further configured such that the top edge assembly includes a sliding sleeve, a top edge plate and a sliding buffer.

Detailed Implementation

[0025] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] Please refer to Figures 1 to 4. This utility model is an automatic deviation correction device for cardboard production, including a conveyor belt 1 and an edge limiting component 2. The edge limiting component 2 includes two side plates 201, two push plates 202, and two top edge assemblies 203. By installing the edge limiting component 2 above the conveyor belt 1, the two side plates 201 in the edge limiting component 2 are respectively fixedly installed on both sides above the conveyor belt 1. The guide rods 202a on one side of the two push plates 202 in the edge limiting component 2 slide through the two side plates 201 respectively, moving one side of the push plate. 202 pushes the cardboard on the conveyor belt 1 against the push plate 202 on the other side, thereby correcting and aligning the cardboard on the conveyor belt 1; by moving the distance between the push plate 202 and the side plate 201 and fixing the push plate 202, when the cardboard is conveyed on the conveyor belt 1, it is pushed and pressed against the plate by the push plate 202 on the other side, so that the edge limiting component 2 can adjust the distance between the push plate 202 and the side plate 201 according to the cardboard of different sizes, thereby correcting the cardboard of different sizes.

[0028] Specifically, the side plate 201 has an L-shaped plate structure. The lower horizontal plate surfaces of the two side plates 201 are fixedly installed on both sides of the upper end of the conveyor belt 1. A set of guide rods 202a are fixedly installed on the surface of the push plate 202. The guide rods 202a on the two push plates 202 face the two side plates 201 and slide through the two side plates 201. The two top edge components 203 are respectively installed at the lower ends of the two push plates 202.

[0029] Furthermore, an adjusting screw 201a is threaded through one of the side plates 201. The end of the adjusting screw 201a near the push plate 202 is rotatably mounted on the push plate 202 near the adjusting screw 201a. By rotating the adjusting screw 201a, the adjusting screw 201a moves spirally on the side plate 201, thereby driving the push plate 202 to move, achieving the technical effect of adjusting the distance between the push plate 202 and the side plate 201.

[0030] Furthermore, a screw handle 201a-1 is fixedly provided at the end of the adjusting screw 201a away from the push plate 202, and an adapter 201a-2 is threadedly connected to the end of the adjusting screw 201a near the push plate 202. An adapter post 201a-3 is fixedly provided at the end of the adapter 201a-2 away from the adjusting screw 201a. The adapter post 201a-3 penetrates the surface of the push plate 202 near the adjusting screw 201a, and an adapter cover 201a-4 is threadedly connected to the outer side of a section of the adapter post 201a-3 penetrating the surface of the push plate 202.

[0031] Furthermore, a push cylinder 201b is installed on the side plate 201 of the conveyor belt 1 away from the adjusting screw 201a. The push cylinder 201b is installed on the side plate 201 away from the adjusting screw 201a. The telescopic end of the push cylinder 201b passes through the side plate 201. The telescopic end of the push cylinder 201b is fixedly installed on the push plate 202 near the push cylinder 201b. The push cylinder 201b pushes the push plate 202 to move, pushing the cardboard on the conveyor belt 1 against the push plate 202 on the other side, thereby straightening and correcting the cardboard on the conveyor belt 1.

[0032] The operation process in this embodiment is as follows:

[0033] Rotate the handle 201a-1 to make the adjusting screw 201a spirally push on the side plate 201, and drive the push plate 202 to move so that the distance between the two push plates 202 is consistent with the size of the cardboard on the conveyor belt 1. The adjusting screw 201a is used to fix the initial position of one push plate 202. The push cylinder 201b pushes the other push plate 202 to push the cardboard on the conveyor belt 1 onto the fixed push plate 202. The push cylinder 201b is used to dynamically adjust the position of the other push plate 202 to achieve automatic correction, thereby straightening and correcting the cardboard.

[0034] Example 2

[0035] Please refer to Figures 1 to 5. Based on Embodiment 1, the top edge assembly 203 includes a sliding sleeve 203a, a top edge plate 203b, and a sliding buffer 203c. By sliding the sliding buffer 203c inside the sliding sleeve 203a, when the push plate 202 moves, the sliding buffer 203c rolls and rubs against the upper surface of the conveyor belt 1, reducing the friction force, so that the movement of the push plate 202 is not affected by the operation of the conveyor belt 1.

[0036] Specifically, the sliding sleeve 203a has an opening facing downwards and its upper end face is fixedly connected to the lower end face of the push plate 202. The sliding buffer 203c is vertically slidably sleeved inside the sliding sleeve 203a. A notch is opened on the side of the sliding sleeve 203a near the opposite push plate 202. A connecting key is fixed on one side of the top plate 203b. The connecting key on the side of the top plate 203b passes through the notch on the sliding sleeve 203a and is fixedly connected to the sliding buffer 203c.

[0037] Furthermore, the sliding buffer 203c includes a ball seat 203c-1, a set of balls 203c-2, and a ball cover 203c-3. The ball seat 203c-1 is vertically slidably fitted inside the sliding sleeve 203a. The balls 203c-2 are made of wear-resistant material and are lubricated to reduce friction with the conveyor belt. A set of hemispherical ball grooves are opened on the lower end plate of the ball seat 203c-1, and each ball 203c-2 is rolled and installed in the ball grooves. A through hole is opened on the plate of the ball cover 203c-3. The ball cover 203c-3 covers the lower end of the ball seat 203c-1, and the balls 203c-2 pass through the through hole. The balls 203c-2 roll in contact with the upper surface of the conveyor belt 1. When the conveyor belt 1 is running, the balls 203c-2 roll on the conveyor belt 1, thereby reducing the friction between the push plate 202 and the conveyor belt 1.

[0038] Furthermore, a set of compression springs 203c-4 is fixedly connected to the upper end of the ball bearing seat 203c-1. The upper end of the compression springs 203c-4 is fixedly connected to the top surface of the sliding sleeve 203a. The compression springs 203c-4 push the entire sliding buffer 203c downwards onto the conveyor belt 1.

[0039] The operation process in this embodiment is as follows:

[0040] When the conveyor belt 1 is running, the cardboard passes between the two push plates 202. The push cylinder 201b repeatedly pushes the push plate 202 to move. In the top edge assembly 203 at the lower end of the push plate 202, the top edge plate 203b contacts the side of the cardboard and flattens the cardboard with the top edge plate 203b at the lower end of the push plate 202 on the other side, thereby straightening and correcting the cardboard.
