Description

Technical Field

[0001] The utility model relates to the technical field of conveying equipment, in particular to a paper feeding conveying device of a boat-shaped paper box machine. Background Art

[0002] At present, in the process of boat-shaped paper box production, it is necessary to transport the cardboard stack (hereinafter referred to as: paper stack) formed by stacking multiple paperboards into the boat-shaped paper box forming equipment. The traditional paper stack loading method is to manually carry the paper stack to the paper inlet end of the boat-shaped paper box forming equipment, and then use a belt to transport each paperboard at the paper inlet end to produce and form each boat-shaped paper box. However, there are many problems in the manual loading of paper stacks into the boat-shaped paper box forming equipment, as follows: (1) The original paper loading method requires the operator to load paper and add paper stacks at the paper inlet end of the boat-shaped paper box forming equipment every few minutes, without any spare time to simultaneously handle the second device, which makes the operator very busy and needs to repeat the action of adding paper stacks, which is labor-intensive. (2) When the paper stack is loaded to the paper inlet of the boat-shaped paper box forming equipment, the paper stack is continuously conveyed and separated by the belt-driven friction of the bottom cardboard of the paper stack; because the paper stack is directly loaded onto the belt and the paper stack is put in vertically without tilting, in the process of separating and conveying the overlapping cardboards, the bottom surface of the cardboard and the top surface of the belt are in horizontal contact, which may easily lead to the contact surface not being tight enough, causing the cardboard to slip and unable to be separated for conveying or the conveying to be paused, resulting in inadequate conveying, resulting in inaccurate subsequent production and reduced product quality, and also resulting in a high molding waste rate. (3) When the paper stack is loaded to the paper inlet, some limiting plates are generally set to block the paper stack, so that only the bottom cardboard is separated and conveyed to the belt, so that the separated cardboard can be continuously conveyed on the belt; but because the cardboard is very thin and the height of the limiting plate used cannot be adjusted, when it is necessary to form cardboards of different thicknesses, it is easy to convey two overlapping cardboards together (that is, the two cardboards are not separated, and the overlapping is conveyed together into the forming process), which will cause the waste rate to increase.

[0003] Therefore, there are still many problems with the paper loading equipment of the boat-shaped paper box machine of the traditional technology, which need further improvement or modification. Summary of the invention

[0004] The utility model aims to overcome the disadvantages of the prior art and provides a paper feeding conveying device for a boat-shaped paper box machine. The paper feeding conveying device for the boat-shaped paper box machine directly discharges multiple paper stacks onto the upper paper conveying belt when the paper stacks are produced. By controlling the induction electric eye, when the paper stacks on the blanking assembly are empty to the sensing position of the induction electric eye, the paper receiving cylinder is controlled to move, and the L-shaped receiving paper board is extended to the discharge end of the upper paper conveying belt. The upper paper conveying belt runs to deliver the paper stacks to the L-shaped receiving paper board. When the paper receiving cylinder is recovered, the L-shaped receiving paper board automatically delivers the paper stacks into the paper discharge cavity formed by the inverted L-shaped supporting plate and the blanking positioning bracket. The downward tilting setting of the inverted L-shaped supporting plate makes the paper stack in a slightly downward tilting state. The paper board at the bottom of the paper stack is separated and pulled out by the running of the paper feeding belt, so as to complete the purpose of separating and conveying the paper pieces one by one. The paper feeding and conveying device can solve the paper feeding limitation of the traditional process. The original requirement that the operator add paper every three minutes is converted to automatic paper feeding, which eliminates the need for operators to manually feed paper. This improves production efficiency and product quality, and allows one operator to operate and oversee three production equipment at the same time, effectively allowing the operator to take time to oversee product quality.

[0006] The paper splicing assembly comprises a paper splicing cylinder, a protruding rod installed on the power output end of the paper splicing cylinder, and an L-shaped splicing paperboard fixedly connected to the protruding rod and capable of extending into the discharge end of the upper paper conveying belt assembly to form an active connection for receiving and supporting the paper stack.

[0007] The blanking assembly comprises an inverted L-shaped supporting plate which is arranged in the opposite direction to the L-shaped receiving paper board and is used for supporting blanking, a blanking positioning bracket which is arranged on the same side as the receiving paper cylinder and faces the open end of the inverted L-shaped supporting plate, and an induction electric eye installed on the blanking positioning bracket for sensing that when the paper stack is empty to a preset value, it drives the receiving paper cylinder to perform a paper receiving action; a cardboard exposing notch for exposing part of the bottom surface of the paper stack is formed between the inverted L-shaped supporting plate and the blanking positioning bracket, and a paper feeding belt is located directly below the cardboard exposing notch, and a gap formed between the top surface of the paper feeding belt and the bottom surface of the blanking positioning bracket is greater than the thickness of one cardboard and less than the thickness of two cardboards.

[0008] Furthermore, the blanking positioning bracket includes a fixed positioning frame, a movable positioning frame that is movably mounted with the bottom of the fixed positioning frame and can adjust the upper and lower heights, and a fine-tuning knob that passes through the fixed positioning frame and is movably mounted with the movable positioning frame and can adjust the height of the movable positioning frame.

[0009] Furthermore, the paper feeding conveying belt assembly includes a motor, a driving wheel connected to the motor, a passive wheel, and a paper feeding conveying belt installed between the driving wheel and the passive wheel for conveying paper stacks.

[0010] Furthermore, the upper paper conveying belt assembly also includes a paper receiving guide support block installed close to the upper paper discharge end and correspondingly connected to the paper receiving end of the L-shaped paper receiving paper board. The top surface of the paper receiving guide support block is an arc-shaped surface facing downward in the direction of the L-shaped paper receiving paper board.

[0011] Furthermore, the bottom supporting surface of the inverted L-shaped supporting plate is an inclined surface that gradually tilts downward in the direction of the blanking positioning bracket.

[0012] Furthermore, the length of the L-shaped paper connecting plate and the length of the reverse L-shaped supporting plate are both shorter than the length of the paper stack.

[0013] Furthermore, the distance between the inverted L-shaped supporting plate and the blanking positioning bracket is equal to the length of the paper stack.

[0014] Furthermore, the side surface of the movable positioning frame facing the inverted L-shaped supporting plate is an arc-shaped surface.

[0015] Furthermore, the paper upper conveyor frame is also provided with a baffle plate located at the outer periphery of one side of the paper upper conveyor belt for positioning and preventing the paper stack from accidentally falling.

[0016] In summary, the paper feeding conveying device of the boat-shaped paper box machine of the utility model directly discharges multiple paper stacks onto the upper paper conveying belt when the paper stack is produced. By using the control of the induction electric eye, when the paper stack on the blanking component is empty and reaches the sensing position of the induction electric eye, the paper receiving cylinder is controlled to move, and the L-shaped receiving paper board is extended to the discharge end of the upper paper conveying belt. The upper paper conveying belt runs to send the paper stack to the L-shaped receiving paper board. When the paper receiving cylinder is recovered, the L-shaped receiving paper board automatically puts the paper stack into the paper discharge cavity formed by the inverted L-shaped supporting plate and the blanking positioning bracket. The downward tilting setting of the inverted L-shaped supporting plate makes the paper stack in a slightly downward tilting state.

[0022] Example 1

[0023] The paper feeding and conveying device of a boat-shaped paper box machine described in the first embodiment is as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, it includes an upper paper conveyor frame 1, an upper paper conveyor belt assembly 2 installed on the upper paper conveyor frame for conveying a paper stack 22, a paper receiving assembly 3 connected and installed corresponding to the discharge end of the upper paper conveyor belt assembly and supporting the paper stack, a blanking assembly 4 located below the paper receiving assembly and used for blanking the paper stack, and a paper feeding belt 5 located below the paper discharge port of the blanking assembly and conveying the bottom paperboard of the paper stack. The paper feeding conveying device is basically composed of four major parts, namely, a paper feeding conveying belt assembly, a paper receiving assembly, a blanking assembly and a paper feeding belt. The paper feeding frame serves as a supporting frame for the entire paper feeding conveying device; the paper feeding belt assembly is used to convey a paper stack formed by stacking a number of paperboards; the paper receiving assembly is used to receive and support the entire paper stack outputted from the paper feeding belt assembly and transfer it to the blanking assembly; the blanking assembly is used to receive the entire paper stack dropped by the paper receiving assembly and fix the paper output position of the entire paper stack; the paper feeding belt sequentially separates and outputs the bottommost paperboard of the paper stack in the blanking assembly, so that pieces of paperboard are separated and transported to the forming process in sequence.

[0024] The paper splicing assembly includes a paper splicing cylinder 6, a protruding rod 7 installed on the power output end of the paper splicing cylinder, and an L-shaped splicing paperboard 8 fixedly connected to the protruding rod and can be extended to form a movable connection with the discharge end of the upper paper conveying belt assembly to receive the supporting paper stack. When paper splicing is required, the paper splicing cylinder drives the protruding rod and the L-shaped splicing paperboard to extend horizontally, and then the plane end of the L-shaped splicing paperboard is horizontally attached to the discharge end of the upper paper conveying belt assembly and forms a movable splicing state with the discharge end; in this way, when the paper stack is output from the discharge end of the upper paper conveying belt assembly, it can smoothly enter the position of the L-shaped splicing paperboard to complete the paper splicing process; finally, the paper splicing cylinder drives the protruding rod and the L-shaped splicing paperboard to reciprocate and pull back to reset to the position directly above the blanking assembly.

[0025] The blanking assembly comprises an inverted L-shaped supporting plate 20 which is arranged in the opposite direction to the L-shaped receiving paperboard and is used for supporting blanking, a blanking positioning bracket 9 which is arranged on the same side as the receiving paper cylinder and faces the open end of the inverted L-shaped supporting plate, and an induction electric eye 10 which is installed on the blanking positioning bracket and is used to sense that the paper stack is empty when the paper output reaches a preset value and drives the receiving paper cylinder to perform a paper receiving action; a cardboard exposing notch 21 which exposes part of the bottom surface of the paper stack is formed between the inverted L-shaped supporting plate and the blanking positioning bracket, and a paper feeding belt is located directly below the cardboard exposing notch, and a gap formed between the top surface of the paper feeding belt and the bottom surface of the blanking positioning bracket is greater than the thickness of one cardboard and less than the thickness of two cardboards. When the paper stack is transported to the top of the blanking component by the L-shaped receiving board, the paper stack will slide into the blanking space formed by the inverted L-shaped supporting plate and the blanking positioning bracket due to gravity, and the paper stack will be shaped and limited in the blanking space, ensuring that the entire paper stack will basically not produce a large degree of deformation or displacement, etc., ensuring the smooth progress of the subsequent paperboard separation and sending to the forming process; when the paper stack falls into the blanking space, part of the paperboard on the bottom of the paper stack will be exposed from the notch of the paperboard, and the bottom surface of the blanking positioning bracket is slightly higher than the position of the notch of the paperboard, so that when part of the paperboard on the bottom When the paper is exposed and pressed tightly on the paper feeding belt, the feeding belt is started, and the feeding belt can be formed to separate the cardboard from the paper pile and transport it to the forming process. The paper pile will sink due to gravity, so that new cardboard on the bottom can be continuously separated to form a continuous cardboard loading production line output; when the paper pile sinks to the position of the induction electric eye in the blanking space (at this time, the remaining amount of the paper pile reaches the set value), the induction electric eye sends a signal to the paper feeding conveying belt assembly and the paper receiving assembly, starting the steps of paper stack transportation-paper receiving-dropping into the blanking space, thereby achieving automated continuous production.

[0026] In the present embodiment 1, the blanking positioning bracket member includes a fixed positioning frame 11, a movable positioning frame 12 which is movably mounted with the bottom of the fixed positioning frame and can adjust the upper and lower heights, and a fine-tuning knob 13 which passes through the fixed positioning frame and is movably mounted with the movable positioning frame and can adjust the height of the movable positioning frame. After a batch of paper stack products is produced, if it is necessary to produce paper stack products of different thicknesses but other dimensions are the same, the height of the movable positioning frame can be adjusted by the fine-tuning knob, so that the gap distance between the bottom of the movable positioning frame and the exposed notch of the paperboard can be adjusted to meet the purpose of separating and outputting paperboards of different thicknesses, and the adjustment is convenient and flexible.

[0027] In the present embodiment 1, the paper conveying belt assembly comprises a motor 14, a driving wheel 15 connected to the motor, a passive wheel 16, and a paper conveying belt 17 installed between the driving wheel and the passive wheel for conveying the paper stack. When the paper conveying belt assembly conveys the paper stack, the driving wheel is driven to rotate by the motor, and the passive wheel is driven to rotate synchronously with the paper conveying belt. The rotation of the paper conveying belt can drive the paper stack to be conveyed to the paper receiving position.

[0028] In this embodiment 1, the upper paper conveying belt assembly also includes a paper receiving guide support block 18 installed close to the upper paper discharge end and correspondingly connected to the paper receiving end of the L-shaped receiving paper board. The top surface of the paper receiving guide support block is an arc-shaped surface facing the L-shaped receiving paper board and gradually downward. The paper receiving guide support block is used to connect the paper receiving end of the L-shaped receiving paper board and the upper paper discharge end. When the upper paper conveyor belt conveys the paper stack to the upper paper discharge end, the paper stack is output through the plane support of the paper receiving guide support block and slides onto the L-shaped receiving paper board; at this time, the bottom surface of the paper stack is jointly supported by the paper receiving guide support block and the L-shaped receiving paper board, and the length of the paper stack supported by the L-shaped receiving paper board is less than the length of the paper stack; when the L-shaped receiving paper board is pulled back to its original position, the L-shaped receiving paper board and the paper stack gradually separate from the upper paper discharge end. During the separation process, the tail of the paper stack slides down along the arc surface of the paper receiving guide support block due to gravity and finally causes the entire paper stack to separate from the L-shaped receiving paper board and slide into the blanking space, completing the blanking process.

[0029] In the first embodiment, the bottom supporting surface of the inverted L-shaped supporting plate is an inclined surface that gradually tilts downward in the direction of the blanking positioning bracket. When the paper stack is placed in the blanking space and supported by the bottom of the inverted L-shaped supporting plate, the bottom supporting surface of the inverted L-shaped supporting plate is appropriately set to a slightly downwardly inclined surface, so that the paper stack can be slightly inclined to the exposed notch of the cardboard and tilted to expose, so that the exposed cardboard is pressed more tightly against the paper feeding belt. The contact and friction between the two are enhanced, so that the paper feeding belt can carry out the cardboard more stably and effectively.

[0030] In this embodiment 1, the length of the L-shaped paper connecting plate and the length of the reverse L-shaped supporting plate are both smaller than the length of the paper stack.

[0031] In this embodiment 1, the distance between the inverted L-shaped supporting plate and the blanking positioning bracket is equal to the length of the paper stack.

[0032] In this embodiment 1, the side surface of the movable positioning frame facing the inverted L-shaped supporting plate is an arc-shaped surface.

[0033] In this embodiment 1, the upper paper conveyor frame is also provided with a baffle 19 located at the outer position of one side of the upper paper conveyor belt for positioning and preventing the paper stack from accidentally falling. The baffle can realize the role of accidentally falling and positioning the paper stack from the upper paper conveyor belt.

[0034] The paper feeding conveying device of the boat-shaped paper box machine directly discharges multiple paper stacks onto the upper paper conveying belt when the paper stacks are produced. By using the control of the induction electric eye, when the paper stacks on the blanking component are empty and reach the sensing position of the induction electric eye, the paper receiving cylinder is controlled to move, and the L-shaped receiving paper board is extended to the discharge end of the upper paper conveying belt. The upper paper conveying belt runs to deliver the paper stacks to the L-shaped receiving paper board. When the paper receiving cylinder is recovered, the L-shaped receiving paper board automatically drops the paper stack into the paper discharge cavity formed by the inverted L-shaped supporting plate and the blanking positioning bracket. The downward tilting setting of the inverted L-shaped supporting plate makes the paper stack in a slightly downward tilting state. The paper board at the bottom of the paper stack is separated and pulled out by the running of the paper feeding belt, so as to complete the purpose of separating and conveying the paper pieces one by one. The paper feeding and conveying device can solve the paper feeding limitation of the traditional process. The original requirement that the operator add paper every three minutes is converted to automatic paper feeding, which eliminates the need for operators to manually feed paper. This improves production efficiency and product quality, and allows one operator to operate and oversee three production equipment at the same time, effectively allowing the operator to take time to oversee product quality.

[0035] The above is only a preferred embodiment of the utility model, and does not limit the structure of the utility model in any form. Any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the utility model still falls within the scope of the technical solution of the utility model.
