Description
Technical Field
[0001] This utility model belongs to the technical field of paper box processing equipment, specifically, it relates to a paper box and cardboard frame folding machine. Background Technology
[0002] In the paper box production process, the folding of the paperboard frame is an important processing step, and the quality of the folding directly affects the forming effect and overall quality of the paper box.
[0003] Currently, most common cardboard box and board frame folding machines on the market are designed for cardboard box and board frames of specific sizes. The position and size of their folding mechanism are relatively fixed. When processing cardboard box and board frames of different sizes, operators often need to change the corresponding molds or make complex adjustments to the equipment. This is not only cumbersome and time-consuming, reducing production efficiency, but also prone to causing a decrease in equipment precision due to frequent mold changes or equipment adjustments, affecting the stability of folding quality. In addition, molds of different sizes need to be made and stored separately, increasing production and storage costs, which is not conducive to the company's large-scale production and economic benefits.
[0004] In view of this, this utility model is proposed. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a paper box and cardboard frame folding machine, which solves the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:
[0007] A cardboard box folding machine includes: a base box, the surface of which has a folding groove, a worktable slidably connected within the folding groove, and a conveying assembly connected to the side of the base box on the folding groove; a bracket connected to the side of the base box, with the lateral end of the bracket positioned above the worktable, a moving block connected to the lateral end of the bracket via a longitudinal drive assembly, a folding pressing block connected to the bottom of the moving block via a lifting assembly, a connecting plate connected to the surface of the moving block, and the bottom end of the connecting plate connected to the front end of the worktable via bolts.
[0008] Optionally, the conveying assembly comprises multiple conveying roller assemblies, and the conveying rollers are connected to an external drive mechanism.
[0009] Optionally, the longitudinal drive assembly includes a first groove formed on the lateral end surface of the bracket, the movable block is sleeved on the lateral end of the bracket, and a first slider corresponding to the first groove is connected in the middle of the movable block.
[0010] Optionally, the longitudinal drive assembly further includes a guide rod and a lead screw connected to the inner wall of the first slide groove. There are two guide rods, located on the left and right sides of the lead screw respectively. Both the lead screw and the guide rod pass through the first slider. The lead screw is threadedly connected to the first slider. The rear end of the lead screw passes through the lateral end of the bracket and is connected to the motor. The motor is fixedly connected to the bracket.
[0011] Optionally, the lifting assembly includes a connecting column connected to the bottom end of the moving block, a fixing plate connected to the bottom end of the connecting column, a folding cylinder connected to the surface of the fixing plate, and the output end of the folding cylinder passing through the fixing plate and connected to the folding pressure block.
[0012] Optionally, the workbench surface is provided with a pressing block groove corresponding to the folding pressing block.
[0013] Optionally, the worktable is connected to the left and right sides with second sliders, and the inner walls of the left and right sides of the folding groove are provided with second sliding grooves corresponding to the second sliders.
[0014] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:
[0015] 1. By setting up a linkage structure of "moving block, connecting plate and worktable" + longitudinal drive component structure of "double guide rod, lead screw and servo motor", the position of the folding mechanism can be infinitely adjusted. It can adapt to the processing of cardboard frames of different sizes without changing the mold, avoiding the cumbersome operation of mold changing in traditional equipment, reducing manpower input and downtime, and improving production efficiency.
[0016] 2. By setting up a lifting component, the pressure and stroke of the folding block can be automatically adapted and adjusted. There is no need to adjust the block structure for different sizes of frames, which further reduces the equipment adjustment process, shortens the production preparation time, and ensures the pressure is adapted when folding different sizes of frames, avoiding quality problems caused by improper pressure, and improving processing stability and product qualification rate.
[0017] 3. By setting up structures such as a second slider and a second slide, the damage to the worktable positioning reference is avoided when traditional equipment frequently changes molds or makes adjustments, reducing equipment accuracy loss, extending equipment service life, and reducing equipment maintenance costs. At the same time, it ensures the consistency of folding accuracy of frames of different sizes during long-term processing, providing stable equipment support for large-scale production of enterprises.

Detailed Implementation
[0029] The present invention will now be described in further detail with reference to the accompanying drawings.
[0030] Example 1
[0031] Please see Figure 1-6As shown, this embodiment provides a cardboard box folding machine, including: a base box 1, a folding groove 6 on the surface of the base box 1, a worktable 7 slidably connected in the folding groove 6, and a conveying component connected to the side of the base box 1 located in the folding groove 6; a support 3 connected to the side of the base box 1, with the horizontal end of the support 3 located above the worktable 7, a moving block 4 connected to the horizontal end of the support 3 via a longitudinal drive component, a folding pressing block 14 connected to the bottom of the moving block 4 via a lifting component, a connecting plate 5 connected to the surface of the moving block 4, and the bottom of the connecting plate 5 connected to the front end of the worktable 7 via bolts.
[0032] The base box 1 serves as the equipment base, and the folding groove 6 on its surface provides a sliding track for the worktable 7, ensuring that the worktable 7 maintains a linear motion trajectory during adjustment, laying the foundation for folding accuracy. The worktable 7 is embedded into the folding groove 6 via a sliding connection, and can move horizontally along the groove according to the length of the cardboard frame, directly carrying the cardboard to be processed and completing the positioning in conjunction with the folding action. The conveying component is located on the side of the folding groove 6, responsible for automatically conveying the cardboard to be processed to the designated position on the worktable 7, and outputting the finished product after folding, reducing manual loading and unloading intervention. The horizontal end of the bracket 3 spans above the worktable 7, and its surface... The longitudinal drive component can drive the moving block 4 to precisely move along the length of the cardboard, realizing stepless adjustment of the folding position. The bottom of the moving block 4 is connected to the folding pressure block 14 through a lifting component such as a cylinder or electric push rod. The lifting component is responsible for controlling the downward pressure and stroke of the pressure block to adapt to the folding requirements of cardboard of different thicknesses. The longitudinal displacement of the moving block 4 can synchronously drive the pressure block to adjust its position to match the folding reference of different sized frames. When the longitudinal drive component drives the moving block 4 to move, the worktable 7 will slide synchronously to ensure that the relative position of the pressure block and the worktable 7 always corresponds accurately, avoiding positioning deviation during the adjustment process.
[0033] Example 2
[0034] Please see Figure 1-6 As shown, in this embodiment, the conveying assembly consists of multiple conveying roller 2 assemblies, and the conveying roller 2 is connected to an external drive mechanism.
[0035] The conveying assembly adopts a combination structure of "multiple conveying rollers 2 + external drive mechanism". Each conveying roller 2 assembly is independently and orderly arranged on the side of the folding groove 6 of the bottom box 1. The external drive mechanism (such as the geared motor 9 and chain transmission system) is connected to each conveying roller 2 through gears or belts, which can synchronously drive all conveying rollers 2 to rotate at a uniform speed. During operation, the cardboard to be processed is placed on the surface of the conveying roller 2 and is smoothly conveyed to the designated position on the worktable 7 with the help of the friction of the conveying roller 2. After the folding is completed, the conveying roller 2 rotates in the opposite direction to convey the finished cardboard from the worktable 7 to the next process, forming a continuous process of "feeding-processing-discharging".
[0036] Example 3
[0037] Please see Figure 1-6 As shown, in this embodiment, the longitudinal drive assembly includes a first groove 8 formed on the lateral end surface of the bracket 3, a moving block 4 sleeved on the lateral end of the bracket 3, and a first slider 10 corresponding to the first groove 8 connected in the middle of the moving block 4. The longitudinal drive assembly also includes a guide rod 18 and a lead screw 19 connected to the inner wall of the first groove 8. There are two guide rods 18, located on the left and right sides of the lead screw 19, respectively. Both the lead screw 19 and the guide rod 18 pass through the first slider 10. The lead screw 19 is threadedly connected to the first slider 10. The rear end of the lead screw 19 passes through the lateral end of the bracket 3 and is connected to the motor 9. The motor 9 is fixedly connected to the bracket 3. The lifting assembly includes a connecting column 11 connected to the bottom end of the moving block 4. A fixing plate 12 is connected to the bottom end of the connecting column 11. A folding cylinder 13 is connected to the surface of the fixing plate 12. The output end of the folding cylinder 13 passes through the fixing plate 12 and is connected to the folding pressure block 14.
[0038] The first groove 8 on the lateral end surface of the bracket 3 provides a motion track for the movable block 4. The movable block 4 is fitted onto the lateral end of the bracket 3, and the first slider 10 connected in the middle is precisely matched with the first groove 8 to ensure that the movable block 4 slides linearly along the lateral end of the bracket 3 and avoids deviation. The two guide rods 18 connected to the inner wall of the first groove 8 are located on the left and right sides of the lead screw 19, respectively, and both pass through the first slider 10, playing a bidirectional guiding role to prevent the movable block 4 from shaking or tilting during the sliding process. The lead screw 19 is threadedly connected to the first slider 10. When the motor 9 (such as the servo motor 9) drives the lead screw 19 to rotate, the first slider 10 is driven along the axis of the lead screw 19 through the threaded transmission. The moving block 4 moves synchronously, and the motor 9 is fixedly connected to the bracket 3 to ensure the stability of the lead screw 19 when rotating and to avoid the transmission accuracy being affected by the vibration of the motor 9. The connecting column 11 connected to the bottom of the moving block 4 is used to fix the fixed plate 12. The folding cylinder 13 installed on the surface of the fixed plate 12 provides power for the lifting action. The output end of the folding cylinder 13 passes through the fixed plate 12 and is rigidly connected to the folding pressure block 14. When the folding cylinder 13 is ventilated, the output end extends or retracts, which can drive the folding pressure block 14 to move up and down. When it extends, the folding pressure block 14 presses down to complete the folding of the cardboard. When it retracts, the folding pressure block 14 resets, which facilitates the conveying of the next cardboard by the worktable 7.
[0039] The surface of the workbench 7 is provided with a pressing block groove 15 corresponding to the folding pressing block 14. The left and right sides of the workbench 7 are connected with second sliders 17. The inner walls of the left and right sides of the folding groove 6 are provided with second sliding grooves 16 corresponding to the second sliders 17.
[0040] The pressure groove 15 on the surface of the workbench 7 corresponds perfectly to the size and shape of the folding pressure block 14. When the folding pressure block 14 is pressed down, it will be precisely embedded in the pressure groove 15. This not only avoids the folding pressure block 14 directly contacting the surface of the workbench 7 and causing wear, but also allows for secondary positioning of the cardboard folding position through the edge of the pressure groove 15, ensuring accurate folding angle. The second sliders 17 on the left and right sides of the workbench 7 form a sliding fit with the second sliding grooves 16 on the left and right inner walls of the folding groove 6, making the workbench 7 slide more smoothly along the folding groove 6 without jamming or deviation. At the same time, it disperses the force on the workbench 7 and extends the service life of the equipment.
[0041] Working principle:
[0042] After the conveying stage is started, the conveying roller 2 connected to the external drive mechanism rotates at a constant speed. The operator places the cardboard to be processed on the surface of the conveying roller 2. The cardboard moves along the preset trajectory by friction until it is accurately conveyed to the designated processing area of the workbench 7 and aligned with the positioning reference. Then the conveying roller 2 stops, and the automatic feeding is completed.
[0043] If the length of the cardboard changes and the folding position needs to be adjusted, start the motor 9 on the bracket 3. The motor 9 drives the lead screw 19 to rotate. Since the lead screw 19 is threadedly connected to the first slider 10 of the moving block 4, and the slider is sleeved on the two guide rods 18 (to restrict rotation), the rotation of the lead screw 19 is converted into the linear motion of the slider along the axial direction, which drives the moving block 4 to slide along the first slide groove 8 of the bracket 3. Since the moving block 4 is connected to the worktable 7 through the connecting plate 5, the worktable 7 slides along the folding groove 6 of the bottom box 1 with the moving block 4 (the second sliders 17 on both sides are matched with the second slide groove 16 of the folding groove 6 to ensure stability) until the pressing groove 15 corresponds to the folding position of the cardboard. The motor 9 stops, and the position adjustment is completed.
[0044] During the folding stage, the folding cylinder 13 is activated, and its output end extends downward, driving the folding pressure block 14 to move downward. After contacting the cardboard, it continues to apply pressure, pressing the folded part of the cardboard into the pressure block groove 15 of the worktable 7. The pressure block groove 15 is adapted to the folding requirements. Under the action of pressure, the cardboard is precisely folded along the edge of the groove to form a qualified angle.
[0045] After the folding is completed, the output end of the folding cylinder 13 retracts upward, the folding pressure block 14 resets and detaches from the cardboard, and then the conveying roller 2 rotates in the opposite direction, using friction to drive the finished cardboard from the workbench 7 to the external discharge area to complete the discharge. The equipment then returns to its initial state and enters the next processing cycle, continuously achieving efficient and precise folding of the cardboard frame.
