Description

Technical Field

[0001] The utility model belongs to the technical field of plastic pallet production equipment, in particular to a hot melt weld cleaning mechanism for plastic pallet production. Background Art

[0002] Hot melt welding is a method of welding by heating the plastic to a molten state and then pressing it together. During the welding process, a heating plate is placed between the two plastic pallets to be welded. Due to the high temperature of the heating plate, the plastic on the contact surface begins to melt gradually, forming a thin molten layer. When the heating time is over, the two partially melted plastic pallet workpieces are quickly put together. The molten plastics penetrate and fuse with each other under the action of pressure to form a solid weld, which then gradually cools and solidifies, eventually firmly connecting the entire plastic pallet together.

[0003] However, due to the characteristics of hot melt welding, after welding is completed, the weld will often bulge slightly due to the accumulation of molten plastic, making the weld surface uneven. This uneven weld not only affects the aesthetics of the plastic pallet, but more importantly, it may also cause stress concentration during use, reducing the pallet's load-bearing capacity and service life.

[0004] Because some plastic pallets are designed with load-bearing capacity and stability requirements in mind, their volume is often set to be relatively large. This not only increases the practicality of the pallet, but also brings certain cleaning challenges. In daily weld cleaning operations, workers can more easily clean the welds on the outer edge of the pallet. These areas are relatively open and convenient for the use of various cleaning tools. When it comes to the key supporting pillars in the center of the pallet, they are located deep in the center of the pallet structure and are often blocked or surrounded by other structural components, making it difficult for workers to directly reach them. In addition, due to the small space, traditional cleaning methods and tools are often not applicable here, making the cleaning of the welds extremely difficult. Therefore, it needs to be improved and optimized. Utility Model Content

[0005] In order to solve the problems raised in the above-mentioned background technology, the utility model provides a hot-melt weld cleaning mechanism for plastic pallet production, which solves the problem that traditional cleaning methods are difficult to reach and effectively clean the welds at the central support pillars of the plastic pallet, because their location is deep and obscured, and the space is small, making cleaning difficult.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a hot-melt weld cleaning mechanism for plastic pallet production, comprising an operating table, wherein fixing mechanisms are respectively provided on both sides of the top of the operating table, wherein the fixing mechanisms include two fixed blocks fixedly mounted on the top of the operating table, and two bidirectional screw rods are rotatably mounted on the sides of the two fixed blocks close to each other, and two moving blocks one and two moving blocks two are threadedly sleeved on the outer wall of the bidirectional screw rod, and two connecting rods two are respectively hingedly mounted on the outer walls of the two moving blocks two, and the other ends of the two connecting rods two are respectively fixedly mounted with mounting blocks, and a cutter and a heating block are respectively fixedly mounted on the outer walls of the two mounting blocks, and the cutter and the heating block are fixedly connected.

[0007] Preferably, two connecting rods 1 are hingedly mounted on the outer walls of the two moving blocks 1 respectively, and a clamping block is hingedly mounted on the outer wall of one side of the two connecting rods 1.

[0008] Preferably, rectangular grooves are respectively opened on the outer walls of the two connecting rods 1, and the two connecting rods 2 respectively pass through the adjacent rectangular grooves and are slidably connected thereto.

[0009] Preferably, a protrusion is fixedly mounted on the bottom of each of the four movable blocks 1, and the four protrusions are respectively adapted to the top of the operating table and are slidably connected to the top of the operating table.

[0010] Preferably, two sliding grooves are respectively provided on the top and bottom of the clamping block, and T-shaped columns are fixedly installed on the top and bottom of the two connecting rods 2, and the four T-shaped columns are slidably connected to the adjacent sliding grooves.

[0011] Preferably, a round rod is fixedly mounted on one side of the two connecting rods that are close to each other, and a cylinder is slidably mounted on the outer walls of the two round rods.

[0012] Preferably, a spacer block is fixedly installed in the middle of the cylinder, and both sides of the spacer block are elastically connected to the adjacent round rods through springs.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The utility model adopts the threaded drive of the bidirectional screw, the hinged connection of the connecting rod, the spatial staggered and cross-design, so that the cutter can penetrate deep into the center of the pallet and clean the weld closely, solving the problem that the traditional method is difficult to reach. This device not only achieves efficient and accurate cleaning of the central support hot-melt weld while clamping the plastic pallet, but also further improves the cleaning accuracy and efficiency by heating and softening the weld material, thereby significantly improving the cleaning efficiency.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 5 As shown, the utility model provides a hot melt weld cleaning mechanism for plastic pallet production, including an operating table 1, and fixing mechanisms are respectively provided on both sides of the top of the operating table 1, and the fixing mechanisms include two fixed blocks 2 fixedly installed on the top of the operating table 1, and a bidirectional screw rod 3 is rotatably installed on the side of the two fixed blocks 2 close to each other, and two moving blocks 1 4 and two moving blocks 2 7 are threadedly sleeved on the outer wall of the bidirectional screw rod 3, and two connecting rods 2 8 are respectively hingedly installed on the outer walls of the two moving blocks 2 7, and the other ends of the two connecting rods 2 8 are respectively fixedly installed with mounting blocks 9, and a cutter 10 and a heating block 11 are respectively fixedly installed on the outer walls of the two mounting blocks 9, and the cutter 10 and the heating block 11 are fixedly connected.

[0023] By rotating the bidirectional screw rod 3, the threaded connection between the bidirectional screw rod 3 and the movable block 2 7 drives the two movable blocks 2 7 to move closer to each other, thereby driving the two connecting rods 2 8 and the cutter 10 to move together. The cutter 10 enters the plastic tray and fits against the outer wall of the middle support column. At the same time, the heating block 11 starts to heat the cutter 10. The heating block 11 ensures that the cutter 10 reaches a suitable working temperature through precise temperature control. This heating process not only improves the cutting efficiency of the cutter 10, but also helps to soften the weld material, so that the cutter 10 can clean the weld more smoothly.

[0024] like Figure 3 As shown, two connecting rods 5 are hingedly mounted on the outer walls of the two moving blocks 4, and a clamping block 6 is hingedly mounted on the outer wall of one side of the two connecting rods 5.

[0025] By rotating the bidirectional screw rod 3, the bidirectional screw rod 3 is threadedly connected to the moving block 1 4, so that the two moving blocks 1 4 move closer to each other, thereby driving the two connecting rods 1 5 to move together, and the two connecting rods 1 5 together drive the clamping blocks 6 to move, and the two clamping blocks 6 move closer to each other, thereby stably clamping the plastic pallet.

[0026] like Figure 2 As shown, rectangular grooves 501 are respectively opened on the outer walls of the two connecting rods 5, and the two connecting rods 2 8 respectively pass through the adjacent rectangular grooves 501 and are slidably connected thereto. The bottoms of the four moving blocks 1 4 are respectively fixedly installed with protrusions 401, and the four protrusions 401 are respectively adapted to the top of the operating table 1 and are slidably connected to the top of the operating table 1.

[0027] By cleverly passing the connecting rod 2 8 through the rectangular groove 501, the principle of spatial stagger and intersection is utilized to ensure that the connecting rod 1 5 and the connecting rod 2 8 can move smoothly without interfering with each other; the four protrusions 401 are respectively adapted to the top of the operating table 1, thereby effectively limiting the movement of the protrusions 401, thereby improving the stability of the device.

[0028] like Figure 4 As shown, two slide grooves 601 are respectively provided on the top and bottom of the clamping block 6 , and T-shaped columns 801 are respectively fixedly installed on the top and bottom of the two connecting rods 8 , and the four T-shaped columns 801 are slidably connected to the adjacent slide grooves 601 .

[0029] The four T-shaped columns 801 are slidably connected to the adjacent sliding grooves 601 , so that the connecting rod 2 8 can slide along the sliding grooves 601 on the clamping block 6 through the T-shaped columns 801 thereon.

[0030] like Figures 4 and 5As shown, a round rod 12 is fixedly installed on the side where the two connecting rods 8 are close to each other, and a cylinder 13 is slidably installed on the outer wall of the two round rods 12. A spacer block 14 is fixedly installed in the middle of the cylinder 13, and the two sides of the spacer block 14 are elastically connected to the close round rod 12 through springs 15.

[0031] Through the sliding installation of the cylinder 13 on the round rod 12 and the elastic connection of the spring 15, the round rod 12 can be adaptively adjusted to a certain extent according to the surface of the weld, ensuring that the cutter 10 can closely fit the weld to clean it.

[0032] The working principle and use process of this utility model:

[0033] The operator places the plastic pallet with the weld to be cleaned on the operating table 1, ensures that the position of the pallet is appropriate, rotates the bidirectional screw 3, and uses its threaded connection with the moving block 1 4 to drive the two moving blocks 1 4 to move closer to each other. The moving block 1 4 is connected to the connecting rod 1 5 through a hinge, which drives the two clamping blocks 6 to move. The two clamping blocks 6 move closer to each other until they stably clamp the plastic pallet to ensure that the pallet does not move or shake during the cleaning process. At the same time, the rotation of the bidirectional screw 3 also drives the movement of the moving block 2 7, but due to the staggered and cross design of the connecting rod 1 5 and the connecting rod 2 8 in space, which is achieved through the rectangular slot 501, they do not interfere with each other, and the moving block 2 7 is hinged. The connected connecting rod 2 8 drives the mounting block 9 and the cutter 10 and heating block 11 thereon to move. The cutter 10 gradually enters the interior of the plastic pallet and fits against the outer wall of the middle support column. The heating block 11 begins to preheat the cutter 10 to ensure that the cutter reaches a suitable working temperature. The cutter 10 uses its high temperature and sharp blade to smoothly cut and clean the excess material at the weld. The continuous heating of the heating block 11 helps to soften the weld material, allowing the cutter to complete the cleaning task more easily. After cleaning is completed, the bidirectional screw 3 is rotated in the opposite direction to make the moving block 1 4 and the moving block 2 7 drive the clamping block 6 and the cutter 10 back to their initial positions respectively, and the cleaned plastic pallet is taken out.
