Description

Technical Field

[0001] The utility model relates to the technical field of heat shrink packaging in the glass industry.

[0002] Specifically, it relates to a novel pallet cutting device. Background Art

[0003] After the glass bottles are produced, they are stacked on pallets and packaged together with film. The packaging method is to wrap the pallet and the goods with heat shrink film as a whole. In the subsequent transportation, the pallet needs to be picked up by a forklift to achieve transfer. The heat shrink film wrapped around the pallet needs to be cut with a slit first, and a hole is formed during the subsequent heat shrinkage to facilitate transfer and transportation.

[0004] The existing pallet cuts are angle cuts. The blade rotates under the drive of the cylinder to achieve the cut. The blade hits the heat shrink film at a certain angle. However, this method has the following disadvantages: there are many working cylinders on site, and sometimes the air pressure is insufficient, and the cut may not be made. This results in subsequent manual cutting, which is not conducive to production. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies of the above-mentioned traditional technology and provide a novel pallet cutting device in view of the deficiencies of the prior art.

[0006] The purpose of the utility model is achieved through the following technical measures: a new type of pallet cutting device, characterized in that it includes a base plate, a first drive device is installed on the base plate, the first drive device drives a mounting plate that moves vertically close to or away from the pallet, a second drive device is installed on the mounting plate, and the second drive device drives a blade that can reciprocate horizontally along the pallet.

[0007] As an improvement of the above technical solution: the first driving device is a first cylinder, the second driving device is a second cylinder, and the movement directions of the first cylinder and the second cylinder are perpendicular to each other.

[0008] As an improvement of the above technical solution: a guide seat is arranged on the bottom plate, a guide shaft is arranged on the mounting plate, the guide shaft is located in the guide seat and can slide along the guide shaft, and the guide seat and the guide shaft are arranged in a one-to-one correspondence.

[0009] As an improvement of the above technical solution: the guide shaft and the guide seat are provided in multiple groups, and are respectively located on both sides of the first cylinder.

[0010] As an improvement of the above technical solution: telescopic rods are arranged on the mounting plate, and the telescopic rods are arranged in multiple groups, and the multiple groups of telescopic rods are located on both sides of the mounting plate.

[0011] As an improvement of the above technical solution: the telescopic rod includes a fixing seat fixed on the mounting plate and a guide rod passing through the fixing seat and being able to slide along the fixing seat.

[0012] As an improvement of the above technical solution: one end of the guide rod close to the fixed seat is connected to a limiting ring, so that one end of the guide rod is always located on the side of the fixed seat close to the first cylinder, and the other end of the guide rod is connected to a pressure block, which is located on the side close to the tray, and the part between the pressure block and the mounting plate is covered with a spring.

[0013] As an improvement to the above technical solution: the distance from the pressing block to the mounting plate is greater than the distance from the blade to the mounting plate.

[0014] Due to the adoption of the above technical scheme, compared with the prior art, the advantages of the utility model are: the blade is driven by the first cylinder to vertically penetrate the film. Compared with the angle penetration in the prior art, the stress at the penetration point is greater and it is easier to puncture, thus eliminating the situation in the prior art where the blade cannot be punctured. Moreover, according to customer requirements, second cylinders with different strokes corresponding to cuts of different lengths can be selected, and the position and length of the cut edge can be controlled and adjusted.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: As attached Figure 1-3As shown, a novel pallet cutting device comprises a bottom plate 1, on which a first driving device is installed, the first driving device drives a mounting plate 5 that moves vertically toward or away from the pallet, and a second driving device is installed on the mounting plate 5, the second driving device drives a blade 2 that can reciprocate along the horizontal direction of the pallet. The first driving device is a first cylinder 3, and the second driving device is a second cylinder 4. The first cylinder 3 is installed on the bottom plate 1, and the output end of the first cylinder 3 is fixedly connected to the mounting plate 5, and the mounting plate 5 moves vertically toward or away from the pallet under the drive of the first cylinder 3. The second cylinder 4 is fixedly connected to the mounting plate 5, and the output end of the second cylinder 4 is connected to the blade 2, and the blade 2 is arranged in a direction away from the first cylinder 3, that is, the blade 2 is arranged in the direction of the pallet, and the second cylinder 4 can drive the blade 2 to move in a direction perpendicular to the movement direction of the first cylinder 3. In this embodiment, the movement directions of the first cylinder 3 and the second cylinder 4 are both in the horizontal direction, and the movement directions of the first cylinder 3 and the second cylinder 4 are perpendicular to each other. When the first cylinder 3 drives the second cylinder 4 and the blade 2 to move toward the tray, the blade 2 moves perpendicular to the heat shrink film and pierces the heat shrink film. Then the second cylinder 4 drives the blade 2 to move linearly, and the blade 2 cuts a linear opening on the heat shrink film.

[0021] In this embodiment, two second cylinders 4 are provided, and two corresponding blades 2 are also provided. Each group can be one blade 2 or two, which is determined according to the actual situation and no specific requirements are made. The second cylinder 4 adopts a three-axis cylinder, which drives a group of blades 2 respectively. Compared with the cylinder diameter in the prior art, the air source pressure requirement is not high. And the vertical penetration of the heat shrink film is compared with the angle penetration in the prior art, the stress at the penetration point is greater, and it is easier to puncture, which eliminates the situation that the prior art cannot puncture. And according to customer requirements, the second cylinder 4 with different strokes can be selected to correspond to different lengths of cuts. The position and length of the cut edge are controllable and adjustable.

[0022] like Figure 1-2 As shown, a guide seat 6 is provided on the bottom plate 1, and a guide shaft 7 is provided on the mounting plate 5. The guide shaft 7 is located in the guide seat 6 and can slide along the guide shaft 7. The guide seats 6 and the guide shafts 7 are arranged one by one. In this embodiment, two groups are provided, which are respectively located on both sides of the first cylinder 3. The movement of the mounting plate 5 can be guided.

[0023] like Figure 1-3As shown, a telescopic rod 8 is provided on the mounting plate 5. In this embodiment, two groups of telescopic rods 8 are provided, and the two groups of telescopic rods 8 are located on both sides of the mounting plate 5. The telescopic rod 8 includes a fixed seat 9 fixed on the mounting plate 5 and a guide rod 10 passing through the fixed seat 9 and sliding along the fixed seat 9. The end of the guide rod 10 close to the fixed seat 9 is connected to a limiting ring 11, so that one end of the guide rod 10 is always located on the side of the fixed seat 9 close to the first cylinder 3. The other end of the guide rod 10 is connected to a pressing block 12, and the pressing block 12 is located on the side close to the tray. The part between the pressing block 12 and the mounting plate 5 is covered with a spring 13. In this embodiment, the distance from the pressing block 12 to the mounting plate 5 is greater than the distance from the blade 2 to the mounting plate 5. When the first cylinder 3 drives the mounting plate 5 to move toward the tray, the telescopic rod 8 first contacts the tray, and then the mounting plate 5 continues to move toward the tray. At this time, the spring 13 is compressed, and the pressing block 12 squeezes the diaphragm until the blade 2 penetrates the diaphragm. The stroke of the first cylinder 3 ends, and the telescopic rod 8 can prevent the diaphragm from moving during the piercing process of the blade 2. During the retreat process, the pressing block 12 is constantly pressed on the diaphragm by the action of the spring 13 to fix the diaphragm. The blade 2 leaves the diaphragm first, and the telescopic rod 8 leaves the tray only after the blade 2 completely exits the diaphragm, to prevent the diaphragm from not being detached during the knife withdrawal process.

[0024] Therefore, the blade 2 will not get stuck in the diaphragm and cannot be withdrawn, because the puncture and withdrawal are horizontal, and there are telescopic rods 8 on both sides to hold the diaphragm and prevent it from moving with the blade 2.
