Description

Technical Field

[0001] The invention relates to the technical field of Teflon conveyor belt packaging, in particular to a palletizing device for Teflon conveyor belt packaging. Background Art

[0002] With the increasing development of intelligent packaging equipment, the packaging efficiency and quality requirements of Teflon conveyor belts are constantly improving. However, the traditional Teflon conveyor belt palletizing method often relies on a lot of manual operations, which is not only inefficient, but also difficult to ensure the accuracy and stability of palletizing. The conveyor belt is prone to loosening during the stacking process, resulting in uneven stacking shapes, affecting subsequent handling and storage. At the same time, traditional palletizing devices usually require manual intervention when adjusting the stacking height, which is not only time-consuming and labor-intensive, but also prone to tilting or collapsing due to improper adjustment, increasing safety hazards.

[0003] With the continuous advancement of automation and intelligent technology, intelligent packaging equipment has been widely used in all walks of life. However, in the field of Teflon conveyor belt packaging, the existing palletizing devices still have some shortcomings. For example, in the process of conveyor belt folding and palletizing, traditional devices are difficult to achieve automatic and accurate folding, which makes the conveyor belt easy to loosen and stacked unevenly. In addition, during the palletizing process, the friction between the conveyor belt and the inner wall of the device can easily scratch the surface of the conveyor belt, affecting the appearance and quality of the product. Moreover, the pallet replacement process of the traditional palletizing device is cumbersome, requiring a lot of manpower and time. There are also many inconveniences when carrying a whole stack of products, which reduces logistics efficiency. Summary of the invention

[0004] The present invention relates to a palletizing device for Teflon conveyor belt packaging, which realizes automatic folding and palletizing of the conveyor belt through the linkage structure of the belt folding frame and the belt folding cylinder, greatly improving the accuracy and efficiency of palletizing. The vertical motion system of the lifting frame and the bracket ensures the stability of layer-by-layer stacking and avoids problems caused by improper manual adjustment. The side guard plate and its built-in anti-wear roller structure not only constrain the alignment of the conveyor belt edge, but also reduce friction damage and protect the conveyor belt surface. The quick-change pallet design on the bracket makes the installation and disassembly of the pallet more convenient, and combined with the design of the fork groove, it further improves the logistics efficiency.

[0005] The present invention provides a palletizing device for Teflon conveyor belt packaging, which specifically comprises: a palletizing frame; a movable base at the lower end of the palletizing frame which is convenient for transfer, and a control box is hung on the side wall of the palletizing frame; one side of the upper end of the palletizing frame is horizontally docked with a conveyor for conveying the Teflon conveyor belt to the palletizing frame; a lifting frame is vertically installed on the back of the palletizing frame, and a bracket is slidably installed on the lifting frame, and the bracket is horizontally located in the inner cavity of the palletizing frame for receiving the stacked Teflon conveyor belts; A horizontal installation belt folding frame is installed on the palletizing rack above the bracket along the conveying direction of the conveyor. At both ends of the belt folding frame, there are belt folding pressing blocks vertically and slidably inserted into the palletizing rack. The inner ends of the two belt folding pressing blocks are both bevel-cut structures inclined downward and inward. The belt folding pressing block closer to the conveyor end is at least the thickness of one Teflon conveyor belt higher than the belt folding pressing block at the other end. When the inner end of one belt folding pressing block on the belt folding frame is inside the palletizing rack, the inner end of the other belt folding pressing block is outside the inner cavity of the palletizing rack. A belt folding cylinder is hung at the bottom of the conveyor, and the end of the piston rod of the belt folding cylinder is fixedly connected to the belt folding frame. The piston rod drives the belt folding frame to reciprocate horizontally to fold and palletize the fed Teflon conveyor belt.

[0006] Optionally, universal wheels for easy movement are provided at the bottom of the moving base.

[0007] Optionally, at one end of the conveyor close to the palletizing rack, a conveying motor is provided to drive the conveying roller to rotate. The rotating shafts of the two conveying rollers of the conveyor pass through the other side and are fixedly connected with synchronous wheels. The synchronous wheels have the same diameter as the conveying rollers. A synchronous belt is rotatably connected between the two synchronous wheels. The length of the synchronous belt is consistent with the length of the material belt of the conveyor. The axle distance between the two roller shafts of the conveyor is consistent with the inner cavity width of the palletizing rack. Corresponding limit switches are respectively provided on the conveyor frame at both ends of the synchronous belt. A triggering protrusion is fixedly provided on the outer surface of the synchronous belt. When the triggering protrusion moves with the synchronous belt to the limit switch, it squeezes the limit switch to trigger, and the belt folding cylinder works. When the limit switch at the end far from the palletizing rack is triggered, the belt folding cylinder drives the belt folding frame to move towards the conveyor end. When the limit switch at the end close to the palletizing rack is triggered, the belt folding cylinder drives the belt folding frame to move towards the palletizing rack end.

[0008] Optionally, a lead screw is vertically and rotatably installed in the middle of the lifting frame. The middle of the rear end of the bracket is vertically and rotatably connected to the lead screw. A lifting motor is installed at the lower end of the lifting frame to drive the lead screw to rotate. Guide rods are respectively provided at the left and right ends of the lifting frame. The guide rods are vertically and slidably connected to the bracket.

[0009] Optionally, telescopic rods are vertically and symmetrically provided at the four corners of the bracket. The upper ends of the telescopic rods are fixedly connected to the tray. Springs are provided on the telescopic rods. The upper end of the tray is an L-shaped groove surface structure. Two card slots are longitudinally and symmetrically opened in the groove surface of the tray. Fork slots for easy forklift handling are provided outside the card slots. The backrest at the rear end of the groove surface of the tray is made of magnet. A pallet is provided above the tray. A card rail for being inserted into the card slot is provided at the bottom of the pallet. The pallet is made of iron material that can be adsorbed by the magnet. The stacked Teflon conveyor belts are stacked on the pallet. The pallet can be pulled out from the tray for transfer and stacking.

[0010] Optionally, the outer end of the tape folding pressing block is a T-shaped structure that stops outside the palletizing rack. Lifting touch switches are provided on the outer side walls of the palletizing rack above the two tape folding pressing blocks. When the tape folding pressing block is inserted into the palletizing rack, it squeezes the lifting touch switch. The lifting touch switch is electrically connected to the lifting motor, and when the lifting motor works, it drives the bracket to move down by a distance equal to the thickness of the Teflon conveyor belt.

[0011] Optionally, side guards are also clamped on the tape folding frames on both sides of the tape folding pressing block. The inner sides of the side guards are flush with the inner cavity edges of the palletizing rack. When the Teflon conveyor belt enters, the edge of the Teflon conveyor belt is always tangent to the inner side wall of the side guard. Anti-abrasion rollers with uniform intervals are vertically and rotatably installed in the inner side wall of the side guard to contact the Teflon conveyor belt. When the tape folding frame moves, the side guard follows to smooth the edge of the Teflon conveyor belt.

[0012] Optionally, when the Teflon conveyor belt falls from the conveyor onto the pallet of the palletizing rack and the end of the Teflon conveyor belt slides along the surface of the pallet to the inner side wall of the palletizing rack far from the conveyor, the trigger protrusion on the synchronous belt also contacts the limit switch near one end of the palletizing rack at this time. The tape folding cylinder drives the tape folding frame to move towards one side of the palletizing rack, and the tape folding pressing block near the conveyor moves inwards into the palletizing rack to press and guide the Teflon conveyor belt to bend. At the same time, the lifting touch switch is triggered, and the bracket moves down by one unit. When the synchronous belt reaches the other side, the trigger protrusion on the synchronous belt also contacts the limit switch far from one end of the palletizing rack at the same time. The tape folding cylinder drives the tape folding frame to move towards the conveyor side, and the Teflon conveyor belt is pressed and bent back again. At the same time, the lifting touch switch is triggered, and the bracket moves down by one unit.

[0013] The present invention provides a palletizing device for packaging a Teflon conveyor belt, which has the following beneficial effects: First of all, through the linkage structure of the tape folding frame and the tape folding cylinder, the device realizes the automatic folding and palletizing of the Teflon conveyor belt. The two ends of the tape folding frame are provided with tape folding pressing blocks with bevel cutting structures, and the height difference design ensures that each bending action can effectively press the conveyor belt to form a tight Z-shaped palletizing path. This structure not only reduces manual intervention but also greatly improves the accuracy and efficiency of palletizing, solving the technical problems of easy loosening of the conveyor belt and uneven stacking in traditional palletizing methods.

[0014] Secondly, the vertical movement system of the lifting frame and the bracket, through the transmission of the lead screw and the lifting motor, realizes the precise downward movement of the bracket. Whenever the tape folding pressing block is inserted into the palletizing rack to trigger the lifting touch switch, the bracket automatically moves down by a distance equal to the thickness of the conveyor belt, ensuring the stability of layer-by-layer stacking. This automatic adjustment mechanism not only simplifies the operation process but also avoids the problems of palletizing inclination or collapse caused by improper manual adjustment.

[0015] In addition, the side guard plate and its built-in anti-wear roller structure play a dual role of constraining the alignment of the conveyor belt edge and reducing frictional damage during the movement of the belt folding frame. The rolling contact between the anti-wear roller and the conveyor belt not only protects the surface of the conveyor belt from scratches but also ensures the smooth movement of the conveyor belt during the palletizing process, solving the technical problems of easy wear and uneven edges of the conveyor belt in traditional palletizing devices.

[0016] Finally, the quick-change pallet design on the bracket realizes the quick installation and disassembly of the pallet through the combination of magnet adsorption and the mortise and tenon structure of the clamping rail. With the design of the fork groove, the handling of the whole stack of products is more convenient and efficient, further improving the logistics efficiency and solving the problems of cumbersome pallet replacement and inconvenient handling in traditional palletizing devices.

All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0022] Embodiment 1: Please refer to Figures 1 to 9 : The present invention provides a palletizing device for packaging Teflon conveyor belts, comprising: a palletizing rack 2; a mobile base 1 facilitating transfer at the lower end of the palletizing rack 2, and a control box 9 is hung on the side wall of the palletizing rack 2; on one side at the upper end of the palletizing rack 2, a conveyor 3 is horizontally butted for sending the Teflon conveyor belt 8 into the palletizing rack 2; a lifting frame 4 is vertically installed on the back of the palletizing rack 2, and a bracket 5 is slidably installed on the lifting frame 4. The bracket 5 is horizontally located in the inner cavity of the palletizing rack 2 for receiving and stacking the Teflon conveyor belts 8; A belt folding frame 6 is horizontally installed on the palletizing rack 2 above the bracket 5 along the conveying direction of the conveyor 3. At both ends of the belt folding frame 6, belt folding press blocks 601 are vertically and slidably inserted into the palletizing rack 2. The inner ends of the two belt folding press blocks 601 are both inclined downward and inward in a beveled structure. The belt folding press block 601 near the conveyor 3 is higher than the other belt folding press block 601 by at least the thickness of one Teflon conveyor belt 8. When the inner end of one belt folding press block 601 on the belt folding frame 6 is inside the palletizing rack 2, the inner end of the other belt folding press block 601 is outside the inner cavity of the palletizing rack 2. A belt folding cylinder 7 is hung at the bottom of the conveyor 3, and the end of the piston rod of the belt folding cylinder 7 is fixedly connected to the belt folding frame 6. The piston rod drives the belt folding frame 6 to reciprocate horizontally to fold and stack the fed Teflon conveyor belts 8.

[0023] Among them, the bottom of the mobile base 1 is provided with universal wheels for easy movement.

[0024] Among them, at one end of the conveyor 3 close to the palletizing rack 2, a conveyor motor 301 is provided to drive the rotation of the conveyor rollers. The rotating shafts of the two conveyor rollers of the conveyor 3 pass through the other side and are fixedly connected with synchronous wheels 302. The synchronous wheels 302 have the same diameter as the conveyor rollers. A synchronous belt 303 is rotatably connected between the two synchronous wheels 302. The length of the synchronous belt 303 is consistent with the length of the material belt of the conveyor 3. The axial distance between the two roller shafts of the conveyor 3 is consistent with the inner cavity width of the palletizing rack 2. Corresponding limit switches 304 are respectively provided on the frame of the conveyor 3 at both ends of the synchronous belt 303. A trigger protrusion 3031 is fixedly provided on the outer surface of the synchronous belt 303. When the trigger protrusion 3031 moves with the synchronous belt 303 to the limit switch 304 and presses the limit switch 304 to trigger, the folding belt cylinder 7 works. When the limit switch 304 at the end far from the palletizing rack 2 is triggered, the folding belt cylinder 7 drives the folding belt frame 6 to move towards one end of the conveyor 3. When the limit switch 304 at the end close to the palletizing rack 2 is triggered, the folding belt cylinder 7 drives the folding belt frame 6 to move towards one end of the palletizing rack 2.

[0025] Among them, a lead screw 402 is vertically and rotatably installed in the middle of the lifting frame 4. The middle of the rear end of the bracket 5 is vertically and rotatably connected to the lead screw 402. A lifting motor 401 is installed at the lower end of the lifting frame 4 to drive the rotation of the lead screw 402. Guide rods 403 are respectively provided at the left and right ends of the lifting frame 4. The guide rods 403 are vertically and slidably connected to the bracket 5.

[0026] Among them, telescopic rods 501 are vertically and symmetrically arranged at the four corners of the bracket 5. The upper ends of the telescopic rods 501 are fixedly connected to the tray 503. Springs 502 are provided on the telescopic rods 501. The upper end of the tray 503 is of an L-shaped groove surface structure. Two card slots 5031 are longitudinally and symmetrically opened in the groove surface of the tray 503. Fork slots 5032 for easy forklift handling are provided outside the card slots 5031. The backrest at the rear end of the groove surface of the tray 503 is made of a magnet. A tray 504 is provided above the tray 503. A card rail 5041 for being inserted into the card slot 5031 is provided at the bottom of the tray 504. The tray 504 is made of an iron material that can be adsorbed by the magnet. Stacks of Teflon conveyor belts 8 are stacked on the tray 504. The tray 504 can be pulled out from the tray 503 for transfer and stacking.

[0027] Among them, the outer end of the folding belt pressing block 601 is in a T-shaped structure and stops outside the palletizing rack 2. Lifting touch switches 603 are provided on the outer side walls of the palletizing rack 2 above the two folding belt pressing blocks 601. When the folding belt pressing block 601 is inserted into the palletizing rack 2, it presses the lifting touch switch 603. The lifting touch switch 603 is electrically connected to the lifting motor 401. The lifting motor 401 works to drive the bracket 5 to move down by a distance equal to the thickness of one Teflon conveyor belt 8.

[0028] When the Teflon conveyor belt 8 falls onto the pallet 504 of the palletizing rack 2 from the conveyor 3, when the end of the Teflon conveyor belt 8 slides along the surface of the pallet 504 to the inner side wall of the palletizing rack 2 away from the conveyor 3, the triggering protrusion 3031 on the synchronous belt 303 also contacts the limit switch 304 near one end of the palletizing rack 2 at this time. The belt folding cylinder 7 drives the belt folding frame 6 to move towards the palletizing rack 2 side, and the belt folding pressing block 601 near the conveyor 3 moves inwards into the palletizing rack 2 to press and guide the Teflon conveyor belt 8 to bend. At the same time, the lifting touch switch 603 is triggered, and the bracket 5 moves down one unit. When the synchronous belt 303 reaches the other side, the triggering protrusion 3031 on the synchronous belt 303 also contacts the limit switch 304 away from one end of the palletizing rack 2 at the same time. The belt folding cylinder 7 drives the belt folding frame 6 to move towards the conveyor 3 side, and the Teflon conveyor belt 8 is pressed and bent back again. At the same time, the lifting touch switch 603 is triggered, and the bracket 5 moves down one unit.

[0029] Embodiment 2, on the basis of Embodiment 1, side guard plates 602 are also clamped on the belt folding frames 6 on both sides of the belt folding pressing block 601. The inner sides of the side guard plates 602 are flush with the inner cavity edge of the palletizing rack 2. When the Teflon conveyor belt 8 enters, the edge of the Teflon conveyor belt 8 is always tangent to the inner side wall of the side guard plate 602. Anti-abrasion rollers 6021 with uniform intervals are vertically rotatably installed in the inner side wall of the side guard plate 602 to contact the Teflon conveyor belt 8. When the belt folding frame 6 moves, the side guard plate 602 moves along to smooth the edge of the Teflon conveyor belt 8.

[0030] The following is a detailed explanation and description of the above parts: The conveyor 3 is horizontally docked with the upper end of the palletizing rack 2. Its conveyor motor 301 drives the synchronous pulley 302 to drive the synchronous belt 303 to circulate. The triggering protrusion 3031 on the belt surface cooperates with the limit switches 304 at both ends to form a linkage control with the belt folding cylinder 7: when the conveyor 3 conveys the Teflon conveyor belt 8 to the position of the palletizing rack 2, the triggering protrusion 3031 activates the limit switch 304 near the palletizing rack 2 end, and the belt folding cylinder 7 pushes the belt folding frame 6 towards the palletizing rack 2 direction, so that the belt folding pressing block 601 near the conveyor 3 end moves inwards to press and bend the Teflon conveyor belt 8; when the Teflon conveyor belt 8 runs to the other end, the limit switch 304 at the far end is triggered, and the cylinder pulls the belt folding frame 6 to reset to complete a folding and stacking operation.

[0031] The lifting frame 4 forms a transmission system with the lifting motor 401 through the lead screw 402, and the guide rod 403 ensures the vertical movement guidance of the bracket 5. The four-corner telescopic rods 501 of the bracket 5 support the tray 503. Its L-shaped groove surface is configured with a magnet back to form a magnetic adsorption with the iron pallet 504, and together with the mortise and tenon structure of the card rail 5041 and the card slot 5031, the pallet 504 can be quickly replaced. The specially designed fork groove 5032 is convenient for the forklift to carry the whole stack of products.

[0032] When the folding belt pressing block 601 is inserted into the palletizing rack 2, its T-shaped outer end triggers the lifting touch switch 603, driving the bracket 5 to move precisely downward by the thickness of one conveyor belt, forming layer-by-layer stacking.

[0033] The side guard plate 602 of the folding belt rack 6 is internally provided with anti-wear rollers 6021, which not only constrain the edges of the conveyor belt to align during the movement of the folding belt rack 6 but also reduce frictional damage through rolling contact. The two folding belt pressing blocks 601 are designed with a bevel-cut structure to form a height difference to ensure that each folding action effectively presses the Teflon conveyor belt 8. Their alternating insertion rhythm into the palletizing rack 2 is perfectly coordinated with the movement of the Teflon conveyor belt 8 and the descending timing of the bracket 5, realizing a continuous Z-shaped palletizing path.

[0034] Working principle: When using this palletizing device for Teflon conveyor belts for packaging, first ensure that the mobile base 1 is stably placed in the working area, and its bottom universal wheels can be fixed through the braking device after initial positioning. Start the electrical system in the control box 9 to make the conveyor 3 start working. The conveyor motor 301 drives the synchronous pulley 302 to drive the synchronous belt 303 to circulate.

[0035] The operator places the Teflon conveyor belt 8 to be palletized at the feeding end of the conveyor 3, and the conveyor belt moves towards the palletizing rack 2 driven by the synchronous belt 303. When the end of the conveyor belt reaches the position of the palletizing rack 2, the trigger protrusion 3031 on the synchronous belt 303 will activate the limit switch 304 near the palletizing rack 2 end. At this time, the folding belt cylinder 7 starts, pushing the folding belt rack 6 towards the palletizing rack 2. The folding belt pressing block 601 near the conveyor 3 end moves inwards, and its bevel-cut structure presses the Teflon conveyor belt 8 to bend, making it fall into the pallet 504 on the bracket 5.

[0036] While the folding belt rack 6 is moving, the T-shaped outer end of the folding belt pressing block 601 triggers the lifting touch switch 603, and the lifting motor 401 works, driving the bracket 5 to move vertically downward by a distance equal to the thickness of one Teflon conveyor belt 8 through the lead screw 402, ensuring that subsequent conveyor belts can be stacked layer by layer. The guide rod 403 ensures the vertical guidance of the bracket 5 during the lifting process, maintaining the stability of palletizing.

[0037] When the Teflon conveyor belt 8 completes one fold on the pallet 504, the synchronous belt 303 continues to operate, driving the conveyor belt to move to the other side. When the trigger protrusion 3031 reaches the limit switch 304 at the end far from the palletizing rack 2, the folding belt cylinder 7 pulls the folding belt rack 6 back to its original position. At this time, the other folding belt pressing block 601 moves inwards, pressing the Teflon conveyor belt 8 to bend back again, forming a Z-shaped palletizing path. At the same time, the lifting touch switch 603 is triggered again, and the bracket 5 continues to move downward by one unit.

[0038] During the whole palletizing process, the anti-wear roller 6021 built into the side guard plate 602 is always in contact with the edge of the Teflon conveyor belt 8, which not only constrains the alignment of the conveyor belt edge, but also reduces friction damage. When the palletizing reaches a predetermined height or quantity, the operator can stop the conveyor 3, pull the support plate 504 out of the pallet 503, and use the fork slot 5032 to move the entire stack of products to the designated location by a forklift. Subsequently, a new support plate 504 is inserted into the card slot 5031, fixed by magnet adsorption, and the next round of palletizing can begin.
