Description

Technical Field

[0001] This utility model relates to the field of carrier plate technology, specifically to a material carrier plate for the feed inlet of a paper box printing machine. Background Technology

[0002] A paper box printing machine is an industrial device used to print text, patterns, and other information onto the surface of a paper box. It is widely used in paper box packaging, trademark printing, and other fields. Its core processes include plate mounting, inking, printing, and paper feeding, and it supports various substrates such as paper and textiles.

[0003] To improve the processing efficiency of paper boxes, traditional paper box printing machines stack multiple cardboards on a pallet and use a forklift to transport the pallet to the feed inlet's conveyor frame. The conveyor frame lifts the pallet, allowing the top cardboard to overlap the underside of the feed inlet's conveyor wheels. The rotating conveyor wheels then move the cardboard onto the conveyor belt. As the cardboard is fed in, the conveyor frame gradually rises, maintaining the conveyor wheels overlapping the surface of the top cardboard, ensuring efficient cardboard transport.

[0004] Although the conveyor frame can rise to control the friction between the cardboard and the conveyor wheel, the cardboard is laid flat and stacked on the pallet. When the cardboard on the side where the conveyor wheel is in contact is warped, unevenly stacked, or has a smooth or uneven surface, the contact pressure distribution between the cardboard and the conveyor wheel is uneven. Traditional conveyor frames only provide vertical position adjustment and cannot form a continuous and stable squeezing force on the side where the conveyor wheel is in contact. As a result, uneven contact pressure can easily lead to insufficient friction of the conveyor wheel, causing slippage or interruption of feeding. Utility Model Content

[0005] The purpose of this utility model is to address the defects and shortcomings of the existing technology by providing a material carrier plate for the feed inlet of a paper box printing machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a material carrier plate for the feed inlet of a paper box printing machine, comprising a carrier plate body and a support plate body disposed on one side of the upper end of the carrier plate body for supporting one side of the paperboard when the paperboard is placed on the carrier plate body, thereby increasing the squeezing pressure on the side of the conveyor wheel. The support plate body is located at the corresponding position on the side of the conveyor wheel.

[0007] A further improvement is that a cavity is formed through the support plate to allow the support plate to undergo concave deformation, thereby reducing the deformation cavity between the support plate and the cardboard.

[0008] A further improvement is that the support plate is provided with several elastic groups located in the deformation cavity to generate elastic deformation when the support plate is compressed.

[0009] A further improvement is that the elastic group includes two arc-shaped elastic sheets symmetrically arranged in the deformation cavity of the support plate. The two arc-shaped elastic sheets are rubber sheets or silicone sheets. The lower ends of the two arc-shaped elastic sheets are fixedly connected to the lower inner wall of the support plate, and the lower ends of the two arc-shaped elastic sheets abut against the upper inner wall of the support plate.

[0010] A further improvement is that a support base plate is provided on the lower end surface of the support plate body, and the support base plate is bonded to the support plate body. The support base plate is a metal plate or a polyethylene plate.

[0011] A further improvement is that a disassembly mechanism is provided between the lower end of the support base plate and the bearing plate body. The disassembly mechanism includes a disassembly slot opened on one side of the upper end of the bearing plate body, a disassembly plate provided at the lower end of the support base plate and in clearance fit with the disassembly slot, and a fixing member provided between the disassembly plate and the bearing plate body for fixing or unfixing the disassembly plate in the disassembly slot.

[0012] A further improvement is that the fastener includes a threaded opening on the side end face of the support plate and connected to the disassembly slot, and a disassembly screw threaded to the side end face of the support plate and located in the threaded opening.

[0013] A further improvement is that the threaded opening is located at the middle position of the side end face of the bearing plate and the disassembly slot, and a top groove is provided at the middle position of the side end of the disassembly plate. The screw part of the disassembly screw is clearance-fitted with the top groove, and the top groove is a circular groove.

[0014] A further improvement is that the support plate is a PVC soft board, a polyethylene board, or a polycarbonate board.

[0015] A further improvement is that the upper side of the support plate is provided with a chamfered surface.

[0016] After adopting the above technical solution, the beneficial effects of this utility model are as follows: when the cardboard is stacked and laid on the support plate, the support plate will support the cardboard located on the side of the conveyor wheel, so that the cardboard in this part is slightly arched, which increases the friction between the cardboard in this part and the conveyor wheel. A continuous and stable extrusion pressure can be formed on the side of the conveyor wheel, and it is not easy for the conveyor wheel to have insufficient friction due to uneven contact pressure, which may cause slippage or interruption of feeding.

[0017] Further benefits: When cardboard is stacked on the support plate, the support plate is squeezed by the stacked cardboard and deformed through the deformation cavity, which can prevent the support plate from making rigid contact with the cardboard and affecting the surface of the cardboard.

[0018] Further effects: By setting two arc-shaped elastic plates, when the support plate is deformed into a depression, it can generate elastic deformation and provide a reaction force in the direction of the cardboard. This not only improves the elastic contact between the support plate and the cardboard, but also allows the two arc-shaped elastic plates to gradually release elastic potential energy to push the support plate back to its original position as the cardboard gradually shrinks. This continuously and automatically applies elastic force upward, ensuring that the edge of the cardboard is always stably lifted.

[0019] Further benefits: The support base plate enhances the support for the two arc-shaped elastic plates and the lower end of the support plate. When the support plate is subjected to long-term pressure and undergoes indentation deformation, the disassembly bolts can be loosened to remove the abutment against the side end face of the disassembly plate. Then, the support plate or support base plate can be pulled along the direction of the disassembly slot to remove the disassembly plate from the disassembly slot. The new support plate can be inserted by aligning it with the position of the disassembly slot through the disassembly plate. When the abutment groove corresponds to the position of the threaded hole, the disassembly bolts can be screwed into the threaded hole, so that the bolt head abuts against the disassembly plate in the abutment groove. The abutment groove further enhances the restriction of the sliding of the disassembly plate within the disassembly slot.

[0020] Further benefits: Replacing the support plate can prevent excessive deformation of the support plate, which would affect the lifting effect on the cardboard.

[0021] Further benefits: The chamfered surface prevents the sharp corners of the support plate from scratching or damaging the surface of the cardboard when the cardboard is stacked and pressed onto the support plate, and can reduce damage to the cardboard when pressure is applied.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0026] See Figures 1 to 4 As shown, the technical solution adopted in this specific embodiment is: a material carrier plate for the feed port of a paper box printing machine, including a carrier plate body 1, and a support plate body 2 disposed on one side of the upper end of the carrier plate body 1 for supporting one side of the paperboard when the paperboard is placed on the carrier plate body 1, so as to increase the squeezing force on the side of the conveyor wheel. The support plate body 2 is located at the corresponding position on the side of the conveyor wheel.

[0027] The support plate 2 has a through cavity 3 for generating a concave deformation to reduce the rigid contact between the support plate 2 and the cardboard.

[0028] The support plate 2 is provided with several elastic groups located in the deformation cavity 3 for generating elastic deformation when the support plate 2 is compressed.

[0029] The elastic assembly includes two arc-shaped elastic sheets 4 symmetrically arranged within the deformation cavity 3 of the support plate 2. The two arc-shaped elastic sheets 4 are made of rubber or silicone. The lower ends of the two arc-shaped elastic sheets 4 are fixedly connected to the lower inner wall of the support plate 2, and abut against the upper inner wall of the support plate 2. A deformation space is formed between the two arc-shaped elastic sheets 4. When the support plate 2 is compressed, the two arc-shaped elastic sheets 4 elastically deform towards the deformation space. When the support plate 2 loses pressure, the arc-shaped elastic sheets 4 return to their original deformation state to support the support plate 2.

[0030] The lower end face of the support plate 2 is provided with a support base plate 5, which is bonded to the support plate 2. The support base plate 5 is a metal plate or a polyethylene plate.

[0031] When the support base plate 5 is set, the lower ends of the two arc-shaped elastic plates 4 are fixedly connected to the upper end face of the support base plate 5. When the support base plate 5 is not set, the deformation cavity 3 is set on the support plate body 2, so that the middle part of the support plate body 2 is hollow.

[0032] A disassembly mechanism is provided between the lower end of the supporting base plate 5 and the bearing plate 1. The disassembly mechanism includes a disassembly slot 6 opened on one side of the upper end of the bearing plate 1, a disassembly plate 7 disposed at the lower end of the supporting base plate 5 and in clearance fit with the disassembly slot 6, and a fixing member disposed between the disassembly plate 7 and the bearing plate 1 for fixing or unfixing the disassembly plate 7 in the disassembly slot 6. As shown in the figure, the disassembly slot 6 is opened along the width direction on the bearing plate 1, and the disassembly plate 7 is also arranged along the direction of the disassembly slot 6. The disassembly slot 6 is opened at the width position of the bearing plate 1, and the opening direction of the threaded hole 8 is perpendicular to the disassembly slot 6.

[0033] The fastener includes a threaded opening 8 formed on the side end face of the support plate 1 and communicating with the disassembly slot 6, and a disassembly screw 9 threadedly connected to the side end face of the support plate 1 within the threaded opening 8. The head of the disassembly screw 9 is either an external hexagonal head or an internal hexagonal head.

[0034] The threaded opening 8 is located at the middle of the side end face of the bearing plate 1 and the disassembly slot 6. The middle of the side end of the disassembly plate 7 is provided with a top groove 10. The screw part of the disassembly screw 9 is clearance-fitted with the top groove 10. The top groove 10 is a circular groove.

[0035] The supporting plate 2 is made of PVC flexible sheet, polyethylene sheet, or polycarbonate sheet. PVC flexible sheet is made by adding plasticizers and stabilizers, and has excellent flexibility and bending resistance, capable of withstanding repeated bending without easily breaking. Polyethylene sheet has good toughness and is not easily broken during cold bending, but its bending performance needs to be adjusted according to the specific formula and process. Polycarbonate sheet can be processed by cutting, drilling, hot bending, etc., and is commonly used in the construction and industrial fields for skylights, sound insulation panels, etc., and can withstand a certain degree of bending.

[0036] The upper side of the support plate 2 is provided with a chamfered surface 11.

[0037] The working principle of this utility model is as follows: When the cardboard is stacked and laid on the support plate 1, the support plate 2 supports the cardboard located on the side of the conveyor wheel, so that the cardboard in this part is slightly arched, which increases the friction between the cardboard in this part and the conveyor wheel. This can form a continuous and stable extrusion force on the side of the conveyor wheel, and it is not easy for the conveyor wheel to have insufficient friction due to uneven contact pressure, which could lead to slippage or interruption of feeding. When the cardboard is stacked on the support plate 1, the support plate 2 is squeezed by the stacked cardboard and deformed through the deformation cavity 3, which can prevent the support plate 2 from making hard contact with the cardboard and affecting the surface of the cardboard. By setting two arc-shaped elastic pieces 4, when the support plate 2 is deformed into a concave shape, it can generate elastic deformation and provide a reaction force in the direction of the cardboard. This not only improves the elastic contact between the support plate 2 and the cardboard, but also allows the two arc-shaped elastic pieces 4 to gradually release elastic potential energy to push the support plate 2 back to its original position as the cardboard gradually shrinks. This continuously and automatically applies an upward elastic force to ensure that the edge of the cardboard is always stably lifted. The support base plate 5 can improve the support for the two arc-shaped elastic plates 4 and the lower end of the support plate 2. When the support plate 2 is subjected to pressure for a long time and causes a dent deformation, the disassembly bolt is turned to remove the abutment on the side end face of the disassembly plate 7. Then, the support plate 2 or the support base plate 5 is pulled along the setting direction of the disassembly slot 6 so that the disassembly plate 7 is taken out from the disassembly slot 6. The new support plate 2 is inserted through the disassembly plate 7 to the position of the disassembly slot 6. When the abutment slot 10 corresponds to the position of the threaded hole, the disassembly bolt is screwed into the threaded hole 8 so that the screw part of the disassembly bolt abuts against the disassembly plate 7 and is located in the abutment slot 10. The setting of the abutment slot 10 can further improve the sliding restriction of the disassembly plate 7 in the disassembly slot 6. Replacing the support plate 2 can prevent excessive deformation of the support plate 2 from affecting the lifting effect on the cardboard. The chamfered surface 11 can prevent the sharp corners of the support plate 2 from scratching or damaging the surface of the cardboard when the cardboard is stacked and pressed on the support plate 2, and can reduce damage to the cardboard under the pressure of compression.
