Description

Technical Field

[0001] This utility model relates to the field of pallet forming technology, and in particular to a paper pallet pressing and forming equipment. Background Technology

[0002] Paper pallets, also known as paper trays, are pallets made primarily of paper materials. They are made of high-strength corrugated cardboard or honeycomb cardboard. Corrugated cardboard is a sheet made by bonding facing paper and corrugated paper formed by corrugating rollers, giving it good cushioning properties. Honeycomb cardboard is made by bonding two facing sheets with a honeycomb paper core, and its internal honeycomb structure gives it excellent compression resistance and load-bearing capacity.

[0003] Paper pallet pressing and forming equipment is a machine specifically designed to process paper materials into pallet shapes. It mainly uses pressure to shape the paper raw materials. The equipment generally includes a pressure system that can provide sufficient pressure to tightly bond loose paper or cardboard. Using honeycomb cardboard as raw material, the equipment compresses the honeycomb cardboard and reinforces the edges through hot or cold pressing to form a complete pallet with sufficient strength. In the past, paper pallet pressing and forming equipment required manual sanding of rough edges after pressing the pallet. However, current paper pallet pressing and forming equipment can directly perform further sanding by machine after pressing, thus saving labor costs. However, the pressing mold of current paper pallet pressing and forming equipment is integrated with the machine, which makes it unable to meet the needs of pallets of different sizes and shapes, resulting in insufficient versatility. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a paper pallet pressing and forming device, which aims to improve the problem of insufficient versatility in the existing paper pallet pressing and forming device because the single mold of the existing paper pallet pressing and forming device cannot meet the pressing needs of pallets of different sizes and shapes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a paper pallet pressing and forming device, comprising a pressing table, a mold slidably connected to the middle of the pressing table, a rotating rod rotatably connected to the lower middle part of the mold, a rotating handle fixedly connected to the bottom of the rotating rod, and a power gear fixedly connected to the top of the rotating rod. Sliding grooves are provided on the front and rear ends of the inner sides of the pressing table and the mold. Racks are slidably connected to the inner sides of multiple sliding grooves. Auxiliary gears are rotatably connected to the left and right ends of the inner side of the pressing table. The adjacent sides of multiple racks are respectively meshed with the front and rear sides of the power gear and the auxiliary gear. A positioning and calibration mechanism is installed in the middle of the pressing table, which is used for positioning and calibrating the paperboard.

[0006] As a further description of the above technical solution:

[0007] The positioning and calibration mechanism includes fixed rods. The front ends of the two fixed rods are fixedly connected at equal distances to the rear side of the pressing table. The rear end of the right fixed rod is rotatably connected to a drive sprocket, and the rear end of the left fixed rod is rotatably connected to a driven sprocket. The drive sprocket is connected to the driven sprocket via a chain. A rocker arm is fixedly connected to the rear side of the drive sprocket, and clamps are fixedly connected to the left and right ends of the front side of the chain.

[0008] As a further description of the above technical solution:

[0009] The outer wall of the handle is fixedly connected with multiple anti-slip sleeves at equal intervals.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the rocker arm is fixedly connected with a rubber sleeve.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the rubber sleeve is provided with anti-slip texture.

[0014] As a further description of the above technical solution:

[0015] A shelf is fixedly connected to the lower end of the pressing table.

[0016] As a further description of the above technical solution:

[0017] X-shaped frames are fixedly connected to both the front and rear sides of the pressing table.

[0018] As a further description of the above technical solution:

[0019] Anti-slip pads are fixedly connected to the four corners of the bottom of the pressing table.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the rotating handle drives the rack to slide to both sides through the rotating rod and the power gear. When multiple racks slide to the corresponding positions, the mold can be removed. After the new mold is installed, the rotating handle is rotated in the opposite direction. With the assistance of the auxiliary gear, the rack returns to its original position to fix the mold. This achieves the effect of convenient mold replacement for the paper pallet pressing and forming equipment, thereby improving its versatility.

[0022] 2. In this utility model, the rocker arm drives two clamping plates to move in opposite directions through the active sprocket, chain and driven sprocket. As the two clamping plates move in opposite directions, the cardboard on the pressing table can be pushed above the mold, thereby realizing the positioning and calibration effect of the positioning and calibration mechanism on the cardboard.

[0030] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 2 and Figure 5This utility model provides an embodiment of a paper pallet pressing and forming device, including a pressing table 1, a mold 3 slidably connected to the middle of the pressing table 1, a rotating rod 4 rotatably connected to the lower middle of the mold 3, a rotating handle 5 fixedly connected to the bottom of the rotating rod 4, the rotating handle 5 driving the rotating rod 4 to rotate, a power gear 6 fixedly connected to the top of the rotating rod 4, the rotating rod 4 driving the power gear 6 to rotate, the pressing table 1 and the mold 3 are provided with sliding grooves 7 at the front and rear ends of the inner side, and racks 8 are slidably connected to the inner side of multiple sliding grooves 7, the sliding grooves 7 are used to install racks 8, the left and right ends of the inner side of the pressing table 1 are rotatably connected with auxiliary gears 9, the adjacent sides of multiple racks 8 are respectively meshed with the front and rear sides of the power gear 6 and the auxiliary gears 9, the auxiliary gears 9 are used to assist the power gear 6 in driving the racks 8 to slide, a positioning calibration mechanism 2 is installed in the middle of the pressing table 1, the positioning calibration mechanism 2 is used for positioning and calibration of the paperboard, and multiple anti-slip sleeves 10 are fixedly connected at equal intervals to the outer wall of the rotating handle 5, the anti-slip sleeves 10 are used for anti-slip;

[0032] Specifically, rotating the handle 5 drives the rotating rod 4 to rotate. When the rotating rod 4 rotates, the power gear 6 fixed on it will also rotate. When the power gear 6 rotates, it will drive the two racks 8 installed in the slide groove 7 of the mold 3 to slide to both sides through meshing. As these two racks 8 slide, they will push the other two racks 8 completely into the slide groove 7 opened in the pressing table 1. When all the racks 8 have slid to the corresponding positions, the mold 3 can be removed from the pressing table 1. After the new mold 3 is installed, the handle 5 is rotated in the opposite direction, and the power gear 6 drives the racks 8 on both sides to slide again. At this time, with the assistance of the two auxiliary gears 9, all the racks 8 return to their original positions, thus fixing the mold 3 in the pressing table 1. The anti-slip sleeve 10 fixed outside the handle 5 can improve its anti-slip performance.

[0033] Reference Figure 3 and Figure 4 The positioning and calibration mechanism 2 includes fixed rods 201. The front ends of two fixed rods 201 are equidistantly fixed to the rear side of the pressing table 1. The rear end of the right fixed rod 201 is rotatably connected to a drive sprocket 202, and the rear end of the left fixed rod 201 is rotatably connected to a driven sprocket 203. The fixed rods 201 are used to fix the drive sprocket 202 and the driven sprocket 203. The drive sprocket 202 is connected to the driven sprocket 203 via a chain 204. The drive sprocket 202 drives the driven sprocket 203 via the chain 204. The driven sprocket 203 rotates, and a rocker arm 205 is fixedly connected to the rear side of the driving sprocket 202. The rocker arm 205 drives the driving sprocket 202 to rotate. The left and right ends of the front side of the chain 204 are fixedly connected to clamps 206. The chain 204 drives the two clamps 206 to move in opposite directions. A rubber sleeve 11 is fixedly connected to the outer wall of the rocker arm 205. The rubber sleeve 11 is used to improve the grip of the rocker arm 205. The outer wall of the rubber sleeve 11 is provided with anti-slip texture 12, which improves the anti-slip performance of the rubber sleeve 11.

[0034] Specifically, shaking the rocker arm 205 causes the drive sprocket 202, which is fixed to the back of the pressing table 1 via the fixing rod 201, to start rotating. When the drive sprocket 202 rotates, it drives the driven sprocket 203, which is also fixed to the other side of the pressing table 1 via the chain 204 and via another fixing rod 201, to rotate synchronously. As the chain 204 rotates outside the drive sprocket 202 and the driven sprocket 203, the two clamps 206 fixed in front also move in opposite directions. As the two clamps 206 move in opposite directions, the cardboard on the pressing table 1 can be pushed above the mold 3. The rubber sleeve 11 fixed outside the rocker arm 205 can improve its anti-slip properties for easy gripping, while the anti-slip texture 12 on the rubber sleeve 11 can improve the friction of the rubber sleeve 11.

[0035] Reference Figure 1 A shelf 13 is fixedly connected to the lower end of the pressing table 1. The shelf 13 is used to place items. X-shaped frames 14 are fixedly connected to the front and rear sides of the pressing table 1. The X-shaped frames 14 are used to improve stability. Anti-slip pads 15 are fixedly connected to the four corners of the bottom of the pressing table 1. The anti-slip pads 15 provide anti-slip effect for the equipment.

[0036] Specifically, the shelf 13 fixed under the pressing table 1 can hold cardboard and other materials, while the X-shaped frame 14 can improve the overall stability of the paper pallet pressing and forming equipment, and the anti-slip pad 15 fixed under the paper pallet pressing and forming equipment can play a role in preventing slipping and protecting the equipment.

[0037] Working principle: When pressing different styles of paper pallets using the paper pallet pressing and forming equipment, firstly, the rotating handle 5 is rotated to drive the rotating rod 4 to rotate. When the rotating rod 4 rotates, the power gear 6 fixed on it will also rotate. When the power gear 6 rotates, it will drive the two racks 8 installed in the slide groove 7 of the mold 3 to slide to both sides through meshing. As these two racks 8 slide, they will push the other two racks 8 completely into the slide groove 7 opened in the pressing table 1. When all the racks 8 have slid to the corresponding positions, the mold 3 can be removed from the pressing table 1. Then, after the new mold 3 is installed, the rotating handle 5 is rotated in the opposite direction, and the power gear 6 drives the racks 8 on both sides to slide again. At this time, with the assistance of the two auxiliary gears 9, all the racks 8 return to their original positions, thus fixing the mold 3 in the pressing table 1. This achieves the effect of convenient mold replacement of the paper pallet pressing and forming equipment, thereby improving its versatility.

[0038] After the cardboard is placed on the pressing table 1, the rocker arm 205 is cranked, which causes the drive sprocket 202, which is fixed to the back of the pressing table 1 by the fixing rod 201, to start rotating. When the drive sprocket 202 rotates, it drives the driven sprocket 203, which is also fixed to the other side of the back of the pressing table 1 by the chain 204, to rotate synchronously. As the chain 204 rotates outside the drive sprocket 202 and the driven sprocket 203, the two clamping plates 206 fixed in front will also move in opposite directions. As the two clamping plates 206 move in opposite directions, the cardboard on the pressing table 1 can be pushed above the mold 3, thus realizing the positioning and calibration effect of the positioning and calibration mechanism 2 on the cardboard.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
