Specific embodiments
[0028] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0029] As Figure 1 and Figure 2 shown, a PU synthetic leather creasing machine includes: a machine body 1, an installation space is provided on the machine body 1, an inlet and an outlet are provided at the end of the installation space, and a roller 2 is arranged inside.
[0030] As Figure 3 shown, an installation groove 3 is provided inside the roller 2, the installation groove 3 is formed by being recessed inward from one end of the roller 2, and the cross section is an octagon, and an inner liner 4 is arranged therein in a matching manner. The octagon is formed by chamfering the four corners of a square.
[0031] As Figure 4 and Figure 5 shown, the cross section of the inner liner 4 is an octagon, which is adapted to the installation groove 3. A roller 5 is arranged on the outer wall of the inner liner 4. There are four groups of rollers 5, which are respectively arranged on four spaced-apart first outer sides of the inner liner 4, and the roller 5 abuts against the inner wall of the installation groove 3. Among them, the first outer side is the side formed after chamfering the four corners of the above-mentioned square. The number of each group of rollers 5 is several, and they are evenly distributed along the length direction of the inner liner 4.
[0032] Preferably, the bottom of the inner liner 4 is in a frustum structure, and its bottom end has the smallest size, so that the inner liner 4 can enter the installation groove 3.
[0033] As Figure 8 shown, the roller 5 is connected to the outer side of the inner liner 4 through a fourth elastic member 15, so that the inner liner 4 and the roller 2 are elastically fixedly connected, and when the inner liner 4 is located inside the roller 2, the fourth elastic member 4 is in a compressed state. In this embodiment, the fourth elastic member 15 is a spring.
[0034] Further, support blocks 16 are arranged on the outer side surface of the inner tank 4 on both sides of the rollers 5. The support blocks 16 are located on both sides of the rollers 5, which can protect the rollers 5 and also limit the rollers 5.
[0035] Meanwhile, a first limiting block 17 is arranged on the inner wall of the installation groove 3, and the first limiting block 17 is correspondingly clamped on both sides of the roller 5. When the inner tank 4 is located inside the drum 2, the upper part of the roller 5 is located between the two first limiting blocks 17 to limit and protect the roller 5.
[0036] As Figure 3 and Figure 6 shown, the drum 2 is provided with pressing plates 6 in the installation groove 3. There are four pressing plates 6, which are respectively arranged corresponding to the four second outer side surfaces of the inner tank 4 distributed at intervals. The second outer side surface is adjacent to the first outer side surface. The pressing plates 6 are connected to the drum 2 through first elastic members 7. Among them, the second outer side surface is the original four sides of the upper square. The first elastic member 7 is a spring. When the inner tank 4 is located inside the drum 2, the first elastic member 7 is compressed, and the pressing plates 6 are tightly connected to the outer side surface of the inner tank 4.
[0037] An inner pressure seat 8 is arranged inside the drum 2. The inner pressure seat 8 is arranged at the bottom of the installation groove 3 and is connected to the drum 2 through a second elastic member 9, and the inner pressure seat 8 can abut against the bottom of the inner tank 4. Specifically, the inner pressure seat 8 is in a frustum shape adapted to the bottom of the inner tank 4. When the bottom of the inner tank 4 abuts against the inner pressure seat 8, the inner pressure seat 8 is sleeved outside the bottom of the inner tank 4 to ensure the contact effect with the inner tank 4. Among them, the second elastic member 9 is preferably a spring, and the number is several.
[0038] As Figure 1 shown, the machine body 1 is provided with a warehouse door 10 corresponding to the inlet and outlet. One end of the warehouse door 10 is rotatably connected to the machine body 1, and the other end is detachably connected to the machine body 1. An outer pressure seat 11 is arranged on its side surface. The outer pressure seat 11 corresponds to the drum 2, and an outer abutment seat 12 is arranged on its side surface. The outer abutment seat 12 corresponds to the inner tank 4. When the warehouse door 10 is closed, the outer pressure seat 11 abuts against the end wall of the drum 2, and the outer abutment seat 12 abuts against the end wall of the inner tank 4.
[0039] As Figure 7 shown, the outer pressure seat 11 is connected to a rotating base 14 rotatably arranged on the side surface of the warehouse door 10 through a third elastic member 13, so that the outer pressure seat 11 and the outer abutment seat 12 can rotate with the drum 2. At the same time, when the warehouse door 10 is closed, the third elastic member 13 is compressed, and can cooperate with the second elastic member 9 to fix the inner tank 4. Preferably, the third elastic member 13 is a spring, and the number is several, which are evenly distributed on the side surface of the outer pressure seat 11.
[0040] Further, an inner warehouse door 19 is arranged at the top of the inner tank 4 for closing the inner tank 4.
[0041] The preferred specific embodiments of the present utility model have been described in detail above. It should be understood that those of ordinary skill in the art can make many modifications and variations based on the concept of the present utility model without creative efforts. Therefore, all technical solutions that can be obtained by those skilled in the art in the technical field based on the concept of the present utility model through logical analysis, reasoning, or limited experiments on the basis of the prior art shall fall within the protection scope determined by the claims.
